LOCK FOR NOTEBOOK COMPUTER OR OTHER PERSONAL ELECTRONIC
DEVICE
FIELD OF THE INVENTION
The present invention relates to security locks for
laptop and/or notebook computers and other hand-held
electronic devices, such as cell phones, personal digital
assistants, personal music players (i.e. iPod ) and the
like.
BACKGROUND OF THE INVENTION
Notebook computer or other personal electronic devices
are increasingly used by students at educational
institutions. They are also used by workers at job sites.
Notebook computers are often referred to as laptop computers,
meaning a portable, foldable computer which can be used while
positioned upon the user's lap. In some instances, "laptop
computer" refers to the term used in the trade for an older
version of a larger portable computer. However, with
increasing streamlining and downsizing of portable computers,
compact, smaller versions are referred to as "notebook
computers", but the terms are generally interchangeable.
In order to safeguard the personal electronic device,
such as a notebook computer, it must be shut down, closed and
transported by the user.
However, it is often advantageous for the user of a
notebook computer to take a break and leave the computer open
and operable at a work station or library study carrel, with
other papers and books left at their current open position.
This leaves the personal electrkonic device, such as a
notebook computer vulnerable to theft.
Moreover, in,the commercial retail environment, it is
advantageous to display consumer electronic devices, such as
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487

notebook computers, cell phones or personal digital
assistants in a secure but visually accessible display.
OBJECTS OF THE INVENTION
It is therefore an object of the present invention to
provide a security lock for a personal electronic device,
such as a notebook computer in an open position.
It is also an object of the present invention to provide
a commercial retail display which allows visual access to
notebook computers, cell phones and personal digital
assistants while safeguarding these devices from shoplifting
theft.
Other objects which become apparent from the following
description of the present invention.
SUMMARY OF THE INVENTION
In keeping with these objects and others which may
become apparent, the present invention is a desk surface
locking base which holds a notebook and/or laptop computer,
or a personal electronic device such as cell phones, personal
digital assistants, personal music players (i.e. iPod ) in a
secure but open position. When locked in place, the notebook
computer or other personal electronic device is secure from
being taken away from the surface to which it is locked.
Furthermo"re, taking advantage of software and/or
software/biometric security systems, the computer or other
personal electronic device will also be unusable by
unauthorized individuals when its owner is away from the area
for a break, telephone call, or other short-term pursuits.
With a few keystrokes, the owner of the computer or other
personal electronic device can resume activity in exactly the
same place as when activity had been suspended. This is
especially useful for leaving an active computer or other
personal electronic device on a study desk or library carrel.

-__ ---- ~he notebook computer or other
personal electronic device lock includes a locking base
having a receptacle for receiving a distal end of a pivotable
locking member pivotably attached at a proximal end thereof
to the locking base. The locking member locks the computer
screen between it and the locking base. The locking base is
fastenable to a notebook computer work surface, such as a
desk top or other table surface, in the vicinity of the
notebook computer. A pin lock secures the locking bar across
the display screen portion of the notebook computer or other
personal electronic device and into a hole in the locking
base, thereby securing the notebook computer or other
personal electronic device in a locked position within the
components of the notebook computer or other personal
electronic device lock.
In another embodiment, the locking base is screwed or
otherwise fastened to the work surface in a permanent
fashion. A locking collar is then removed from the base and
then-placed over-the liquid-crystal display (LCD) screen of
the open notebook computer or other personal electronic
device within the framework of the locking base. A lock,
such as a padlock, is then uaed to lock together the locking
collar and the locking base, thereby making it impossible to
remove the notebook computer or other personal electronic
device from the work surface.
In this embodiment, the notebook computer or other
personal electronic device locking assembly includes a
locking base for being secured to a working surface, wherein
the locking base has a rear wall to receive a keyboard
portion of the notebook computer or other personal electronic
device with a screen portion of the notebook computer or
other personal electronic device in the open position resting
parallel to the rear wall. The rear wall has a rearwardly

e-x~e-i1uing .Locxzng r1.ange along a top edge of the rear wall. A
locking frame includes a second rear wall having side walls
and a locking bar joining the side walls, wherein the locking
frame is adapted to slide over the screen portion of the
notebook computer or other personal electronic device in the
open position, with the second rear wall between the screen
portion and the first rear wall and the locking bar extends
across a front surface of the screen portion.
This second rear wall has a rearwardly extending locking
flange along a top edge of the second rear wall on top of,
and flush against, the locking flange of the first rear wall.
The side walls of the locking base have tabs bent toward the
computer or other personal electronic device, with the
locking bar falling behind the bent tabs, when the locking
frame is deployed on the notebook computer or other personal
electronic device, thereby preventing removal of the notebook
computer,or other personal electronic device from the locking
base. Additionally, locking holes in both flanges are aligned
with each other to receive a padlock to lock the locking
frame to the locking base.
Fasteners are employed to attach the locking base to the
working surface, so that the fasteners are kept under the
keyboard portion of the computer or other personal electronic
device.
The lower edges of the rear walls are raised a
sufficient distance to allow access to connectors on a rear
surface of the keyboard portion of the computer or other
personal electronic device.
Preferably, an optional cage is attached to a rear of
the first rear wall to house an auxiliary battery, charger or
battery eliminator.
In an alternate embodiment, an elongated framework of
the locking base is used that supports the LCD screen of the
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
notebook computer at the proper viewing angle, just as in the
preferred embodiment. In this case, however, the locking
device is a transparent screen cover, such as of LEXAN
polycarbonate, which is placed over the screen and then
5 locked to the locking base with a lock, such as a padlock.
This panel is also a screen protector. This is a desirable
feature for a demo station at a retail outlet, to display and
demonstrate a notebook computer or advertise another product.
Using an auxiliary locking flange, this embodiment is also
compatible with the locking collar of the preferred
embodiment. This use mode does not obscure viewing of the
LCD screen directly, when viewing the display screen through
the transparent polycarbonate sheet. Similar smaller locking
bases with polycarbonate or other strong locking panels can
be used to display and demonstrate consumer devices, such as
personal digital assistants (PDA's), scientific calculators,
and cell phones, on store shelves.
This embodiment may also have an optional accessory cage
made of heavy wire mesh or perforated metal, which can be
attached to the back portion of the locking base. This
securely contains a battery charger/eliminator for the
notebook computer.
In this embodiment with a transparent screen cover, the
notebook computer or other personal electronic device locking
assembly includes a locking base secured to a working
surface, with the locking base having a pair of side walls
and a rear wall to receive a keyboard portion of the notebook
computer or other personal electronic device, wherein a
screen portion of the notebook computer or other personal
electronic device is oriented in the open position, resting
adjacent to the rear wall. This rear wall has a rearwardly
extending locking flange along a top edge thereof.

'The trarisparent'""1'ocking frame has a surface adapted to
rest adjacent to, or against, a front surface of the screen.
A top wall is adapted to rest against a top surface of the
screen portion of the computer or other personal electronic
device, with a rear wall extending down from the top wall,
adjacent to a rear surface of the screen portion of the
notebook computer or other personal electronic device. A
rearwardly extends flange from a bottom edge of the rear
wall, with the rearwardly extending flange positioned
adjacent to the rearwardly extending locking flange of the
locking base.
In this embodiment, locking holes in both flanges are
aligned with each other to receive a padlock, to lock the
transparent locking frame to the locking base.
In this embodiment, an optional shelf or shelves may be
provided to display handheld electronic accessories, such as
cell phones, PDA's, calculators, video game controls, etc.,
for retail viewing purposes through the transparent screen
-- - -
cover.
in yet another embodiment, the pivoting locking rod,
locking collar or transparent polycarbonate locking panel is
replaced by a telescoping rod, a vinyl covered steel cable,
or a flexible tubing covered chain. Like the pivoting rod
version, this embodiment therefore eliminates the removable
portion of the locking base system (such as the locking
collar or transparent polycarbonate panel), and instead uses
a locking device that is permanently attached to one side of
the locking base itself. This locking device is also locked
with a padlock by first passing the distal end of the locking
member through a hole in the opposite side panel member of
the locking base thereby preventing removal of the notebook
computer or other personal electronic device.

In this embodiment, the notebook computer or other
personal electronic device locking assembly includes a
locking base secured to a working surface, with the locking
base having a pair of side walls and a rear wall to receive a
keyboard portion of the notebook computer or other personal
electronic device. A screen portion of the notebook computer
or other personal electronic device is held in the open
position, resting against and/or parallel to the rear wall,
with the side walls extending past a front surface of the
screen portion. A telescoping locking bar or flexible locking
cable is hinged at one end to one of the side walls, in front
of the screen portion. An opposite end of this telescopic or
flexible locking bar or cable has a plug with an opening
therethrough. An opening in the other of the side walls is
configured to align with the opening in the plug, when the
locking bar is rotated across a front surface of the screen
portion, with the plug positioned adjacent the other of the
side walls to accommodate a padlock, to lock the notebook
computer or other personal electronic device into the locking
base. ,
In a further embodiment the computer lock or electronic
device lock is attached to a horizontal desk or work surface
via a locking base which is separate from the computer lock
itself. The computer lock is then slipped into the locking
base from the side and both the computer and locking base are
then secured to the work surface. In this manner, no holes
are drilled into the work surface, and the locking base is
removable yet secure. The locking base'is secured to the work
surface by a clamp which goes over the front edge and engages
the bottom surface via a screw with a pointed end which is
tightened so as to indent the underside and thereby attach.
The screw itself can have a security head such as an allen
socket with a concentric protruding rod which prevents the
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
8
use ot a simpie alien wrench. A specialty security allen
wrench with a hole to accommodate the protruding rod is
required for the initial attachment as well as subsequent
removal. A side bracket attached to the clamp also
accommodates a mailbox type key lock which can be used to
deny access to the attachment screw head for an extra measure
of security. If the key lock is used, an ordina'ry non-
security screw can be used since the lock tang itself will
adequately secure the screw. The computer lock used with this
embodiment has a horizontal frame member with two vertical
side brackets at each end attached to base plates which can
be screwed to a work surface as in the previous embodiments
or used with the locking base.
A bar which is captively attached to one bracket secures
the bottom of the notebook computer display when the other
end is passed through a hole in the distal bracket and a key
lock is then slipped over the bar end which has a groove
compatible with the lock.
_
In an alternate embodiment wherein a clamp wraps around
a work surface to lock the notebook computer or other
personal electronic device in place, the clamp itself may be
the locking base itself, connected to the personal electronic
device by a cable or other locking connection.
In another embodiment, the above noted computer lock or
electronic device lock is attached to directly to a
horizontal desk or work surface by fasteners.
Yet another embodiment of a computer lock, the lock has
a continuously width adjustable feature to accommodate
computers with a variety of display width sizes. It includes
a left portion with vertical bracket, base attachment plate,
horizontal member, and captive lock bar. A right portion has
a vertical bracket, base plate and hollow horizontal member
sized to receive the left horizontal member in a telescoping

-Lasnion. =.rne locxing bar is fabricated of a left portion
which is a threaded tubing member having coarse threads. The
right portion of the locking bar is a solid member with
mating external threads on its long end. This computer lock
is used with the locking base of the previous embodiment to
take advantage of its telescoping feature. (It can also be
screwed down to a work surface directly, but the adjustable
feature would be defeated unless screws are moved to other
adjustment holes.)
To use the computer lock, the user places a notebook
computer within the side brackets, and then pushes the sides
in adjacent to the computer display. Then the user screws the
distal end of the locking bar in or out to facilitate the end
fitting through the lock holes on the right bracket. When
locked with a key lock, the bar will secure the computer and
prevent the spreading of the side brackets.
In a related embodiment, the width adjustable feature is
discrete instead of continuous. Although any suitable width
adjustment mechanism can be used, a suggested type uses a peg
which fits into a hole in the larger of the two telescoping
members. The inner telescoping member has a series of holes
which define the width steps when in registration with the
single hole of the larger/outer telescoping member. The peg
locks the outer hole to one of the inner holes.
In another embodiment, the locking base described above
is integrated with a computer lock or electronic device lock
in a single unit. Thus the computer or other personal
electronic device lock is now directly attached to the work
surface via a clamp that goes over an edge of a work table
and locks into the bottom surface of the work table.
In yet a related embodiment, the integrated locking
base/computer or other personal electronic device lock has
two pivots from the clamp end to the computer or other
CA 02566151 2006-11-08
WO 2005/111764 10 PCT/US2005/016487
personal electr'orriic device lock so that much positional
freedom is afforded the locked computer or other personal
electronic device over the work surface. For example, this
pivoting embodiment can be used on corners of work tables.
In a preferred embodiment for consumer use, a low
profile locking base with a narrow footprint is used. Due to
its smaller dimensions, less material is required. Since it
can be stamped and formed from a single rectangular sheet
with little waste, the process for manufacture is very
efficient. Heavy gage aluminum sheet or stainless steel sheet
can be used. It is therefore lighter and more economical.
In one application this locking base is permanently
screwed down to the work surface, and the user would have his
or her own pin lock, to secure the locking bar across the
display portion and into the base back, thereby securing the
notebook computer or other personal electronic device.
However, the preferred mode of use for this embodiment
is to combine the locking base with a cable and clamp as a
portable kit which fits into a convenient tubular carrying
case. The clamp is attached to the work surface or to a table
leg or any convenient non-movable structure in the vicinity.
This clamping of the clamp to a work surface is
accomplished by tightening a clamp screw against the work
surface, such as a table top or desk top. The clamp screw
extends from a clearance hole in a container, such as a short
tube, with a large axial hole at the distal end that
accommodates the screw head. An appropriate tool compatible
with the type of screw head used is entered from the distal
hole to tighten or loosen the clamp while also capturing the
short tube; this can be an allen wrench, a screwdriver, or a
hex head driver as appropriate. ,
The cable has a small end ferrule with a transverse hole
on one end and a ferrule with a larger end attached to the
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
11
cd.sstal ena ot tne cable. A transverse hole in the lower
portion of the short tube accepts the ferrule and cable, but
is sized to prevent access to the larger end of the distal
ferrule.
In use, the clamp is attached to the structure, such as
a desk top, as described; then the cable is threaded through
the transverse hole in the short tube. The end of locking bar
is passed through the cable ferrule with the transverse hole
prior to locking it to the locking base. In this manner,
although the computer or other personal electronic device can
be moved around on the work surface, it is secured by the
cable.
It is noted that the cable being threaded through the
transverse hole in the container, such as the short tube,
denies access to the clamp screw head. The cable must be
removed before the clamp can be loosened from underneath of
the desk top or other work surface.
In an alternate embodiment of the clamp screw
subassembly of this preferred embodiment, no tool is required
to tighten or loosen the clamp. For example, a hollow knob
with a captive locking member, such as a clamp screw,
emerging from a clearance hole in an end cap, is used.
The clamp screw has a tall head and can be a hex, square
or other geometric configuration. A recess with a
configuration matching the screw head is formed into the
inside surface of the end cap such that a slight pull on the
knob against the captive screw,head (i.e.- away from the
clamp) will seat the head into the recess with a slight turn.
Thus the end cap is a socket wrench used to either tighten or
loosen the clamp.
A strategically placed offset transverse hole is
prevented from accepting the cable by the screw head if the
screw head is seated in the wrench recess.
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
12
By pusning up on tne end of the knob (toward the clamp),
clearance for the cable to enter through the transverse hole
adjacent to the screw and between the head and end cap is
formed. Thus, the screw head is spaced apart from the end cap
socket wrench recess as long as the cable is present. If the
knob is turned while the cable is installed, it will just
turn freely with no ability to loosen the clamp even if force
away from the clamp is used. The cable must be removed before
the clamp can be loosened.
In a further embodiment of this invention, a notebook
computer or other personal electronic device is provided with
a security hole through the hinge area between the display
and the base, through the edge of the display, or diagonally
through a corner of the base. A protruding spike or rod, with
a head on one end and a transverse hole near the distal end,
is used to secure the computer or other personal electronic
device. The spike or rod is inserted through the security
hole, and a ferrule on the end of a secure cable is then
inserted through the transverse hole of the spike or rod, and
is locked by a pin lock compatible with the groove feature at
its distal end.
In a variation of this embodiment, the spike or rod is
replaced by a captive security rod with a transverse hole. In
one design, this security rod is stored in a one end of the
hinge in a direction co-linear with the hinge.
In an alternate design, the security rod can rise
vertically from the computer base or base of the personal
electronic device. A small knob is attached to grasp the rod
which may be stored .in the recess by a quarter-turn feature
or by a magnetic force.
An alternate type of spike locking feature does not
depend on the use of a secure cable; a longer separate spike
is used. it is designed to penetrate through a hole in a
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
13
convenient location in the computer base or personal
electronic device base from the top, through the base
thickness, and further through a pre-drilled hole in the
table or desk top. This long spike has a transverse hole
which emerges beneath the table top. A pin with a groove near
its distal end is then inserted through the transverse hole
of the long spike and locked by a pin lock.
In a further alternate embodiment, the protruding rod
may take the form of a thin rigid or flexible strip. The
strip may be inserted within a thin, longitudinally extending
hole, such as a slot, within the body of the personal
electronic device, such as a notebook computer.
On the other hand, if the notebook computer has a hinge
between the display screen and the main body of the personal
electronic device, such as in a hinged notebook computer,
cellphone or personal digital assistant (PDA), then, if the
strip is flexible, it can be inserted within the hinge gap
between the display screen and main body of the device, such
as a keyboard portion of a notebook computer.
The thin, flexible or rigid long rectangular strip
includes a wedge stop at a proximal end and a distal end
being thin enough to weave within the slot of a personal
electronic device, or through the hinge gap of a hinged
instrument such as the gap between display and keyboard of a
notebook computer. If the rectangular strip is flexible,
preferably, the thickness of this strip is between 0.004
inches and 0.064 inches. The composition of the flexible
strip is flexible reinforced plastic or metal such as heat
treated steel shim stock. Springy stainless steel shim type
stock is also a useful material as well a variety of other
steel alloys.
After the distal end of the locking strip is passed
through the slot in the personal electronic device, or
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
14
alternatively through the hinge gap in the device being
secured, it is clamped by a strip-holding locking clamp,
which itself is attached to the work surface, or is otherwise
secured to it as by a secure cable. The strip-holding clamp
may have locking jaws with serrations which aggressively grip
the distal end of the locking strip when a key lock is closed
by a matching key. The lock is similar to a mailbox lock with
a tang that engages a lock recess in the lower base section
of the locking clamp thereby overcoming a spring force which
keeps the jaws apart slightly when not locked. The key is
also used to unlock the two mating jaws to release the
locking strip and thereby unsecure the device. In a library
environment, both the key for a particular clamp as well as a
locking strip can be borrowed from a librarian to secure the
device in a locked state.
In an alternate embodiment of the locking clamp, the
distal end of the locking strip is inserted in the clamp end
through a slot formed by two upright members and a robust
leaf spring attached to a pivoted handle. The handle is
pressed down toward its distal end (thereby offering much~
mechanical advantage for the operation) bending the leaf
spring thereby clamping the distal end of the locking strip
in a slight recess with transverse serrations in the clamp
base. The shackle of an ordinary,key or combination padlock
is then passed through loops attached to the clamp base as
well as a loop at the distal end of the handle (in
registration) and locked. By locking the handle in a down
position, the device is kept secure by frictional forces
opposing pull-out arising from the normal spring force. In
this manner, any person with an appropriate padlock and a
locking strip can lock his own device to a work surface using
any available clamp. The need to receive from and return to a
librarian a specific key is eliminated.

WO 2005/111764 15 PCT/US2005/016487
In an a.lternaze eiLu..,uaiment of the locking strip itself,
whether it be flexible or rigid, a large hole is provided
near the distal (free) end of the strip. This permits a
variety of methods of locking the strip to the work surface
in lieu of a clamp. In one method, a round stud with a
transverse hole near its distal end is attached to the work
surface in a perpendicular orientation (sticking up). The
locking strip is inserted through the hinge gap in the device
to be locked and then the hole in the locking strip is passed
over the stud; the shackle of an ordinary key or combination
padlock is then passed through the transverse hole in the
stud thereby locking the strip to the work surface. In a
second method, a secure cable with a stud at its end is
provided. The cable stud is passed through the hole in the
locking strip, and then a cable lock that fits the stud is
locked onto it thereby locking the strip to the secure cable.
In a third method, a free cable with a stop member
permanently attached at one end is passed through the hole in
the locking strip. The cable is then looped or otherwise
secured to (or adjacent to) the work surface.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 shows locking base 1 for a notebook computer
lock, which is secured to a working surface by fastener
holes, such as screw through holes 4 in base mounting pads 3.
A back surface 10 is tilted at angle "X" to provide a good
viewing angle of the computer screen. Side panel members 6
with bent tabs 7 provide a space for sliding locking collar
2. Locking flange 8 with a locking hole, such as padlock
hole 9, is used to secure locking collar 2 with flange 14 via
hole 15, which is in positional registration with hole 9 when
mated. Width "W" is wider than the widest notebook computer

of other personal electronic device to be accommodated by
this locking base system. Locking bar 12, attached to the
distal ends of sides 13, actually secures the notebook
computer or other personal electronic device. This is the
preferred embodiment. The display screen portion rests within
space 16 between sides 13. In use, the keyboard portion of a
notebook computer or other personal electronic device would
deny access to the fasteners, such as retaining screws, in
holes 4.
Side panel members 6 may have one or more ports 6a to
accommodate computer cables therethrough.
Figures 2, 2A, 2B and 2C show how locking collar 2 is
placed over notebook computer screen 19 and then upon flange
14, and is locked to lower flange 8 via a lock, such as
padlock 20. Keyboard 18 fits between sides 6. Space 5 is
created by a raised back panel 10 so as to permit access to a
variety of connectors at the back of computer keyboard
portion 18. Figure 2 also shows an optional compartment 42
for a power source accessory 43, such as an auxiliary battery
charger or battery eliminator, wherein compartment 42 extends
between power flange 8 and further lower flange 8A.
Figure 2D shows the notebook computer being used by a
person at a work station;
In an alternate embodiment shown in Figure 3, upright
portion 25 supports the entire height of screen 19 above
raised back panel 10 mounted upon base pads 3. This can also
be shown in Figure 4. Figure 3B shows another example of a
lock 20a, which can be used in lieu of padlock 20.
Figure 3A shows a further alternate embodiment where
shelves 36 and 36a are depicted supporting electronic
handheld devices such as folding cell phone 37a, upright cell
phone 37b, marine VHF radio 37c, personal digital assistant
37d, calculator 37e and video game pad controller 37f.

A transparerit parn.el, such as LEXANO polycarbonate panel
30, shown in Figure 5, is used as a locking frame, by sliding
it over screen 19 within the four tabs shown in Figure 3 at
the distal corners of upright 25.
Panel 30, shown in Figures 4-7, has a top portion 32 and
a locking flange 33 with padlock hole 35. In use, this hole
is in positional registration with that of upper locking
flange 27 shown in Figure 4. A padlock 20 or other small
lock 20a can be used to secure the two members together.
Front face 31 of transparent panel 30 protects the surface of
computer screen 19. This can be used to advantage in a
retail demo environment. Alternately, the locking collar of
Figure 1 can be used with base of Figure 3 by locking into
lower locking tab 26; this would offer a better unencumbered
view of screen 19.
Figure 8 shows the addition of an optional battery pack
housing cage 42 feature to the locking apparatus of the
embodiment shown in Figure 1, although it can be used with
any of the embodiments herein;
The optional power source component 42 of Figures 2 and
8 can be added to any of the embodiments of this invention,
including those shown in Figures 3-51. It is preferably a
cage made of heavy duty wire screen or perforated metal that
is attached (as by welding or rivets) to a rear panel, such
as panel 41 in Figure 8. This provides a secure compartment
42 for a power source accessory 43, such as an auxiliary
battery, charger, or battery eliminator.
Compartment 42 is also shown in the side view of Figure
9.
In a further alternate embodiment, shown in Figure 10, a
locking base using a telescoping rod 54 is shown. In this
embodiment, there is no member such as locking collar 2 or
transparent panel 30 that can be readily removed from the
locking base when a computer or other personal electronic
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
23
device is not secured to the base. This should reduce the
incidence of vandalism or theft of the removable item which
would render the base unusable. In Figure 10, one end of bar
54 is attached to the left side panel member 51 of base 50
via a pivotable fastener, such as ball joint 53. After the
notebook computer or other personal electronic device is
inserted between sides 51 and 52, bar 54 is swung over the
lower (hinge) portion of the notebook computer's screen, such
as a liquid crystal display (LCD) screen and is elongated so
as to insert lock plug 55 through locking hole 56 in right
side 52. A lock (not shown), such as padlock 20, is then
inserted through the hole in plug 55 thus locking computer to
bas e .
Alternate locking members include locking members such
as vinyl clad steel cable 60 shown in Figure 11, and the
flexible tubing clad chain 65 shown in Figure 12. These two
devices do not require a ball joint attachment to left flange
51. Cable 60 can be simply inserted through a hole in flange
51 and then retaining washer 61 can be permanently attached
as by spot welding. Lock plug 55, used as for telescoping
rod, is attached to the distal end of cable 60. Chain 65 can
be attached to flange 51 in a similar fashion by attaching
washer 66 to its proximal end after threading through a hole.
The distal end of chain 65 has an elongated link 67 with stop
washer attached. The padlock is engaged through this link
after it emerges through hole 56 in side 52.
Figure 13 shows an alternate embodiment using a separate
locking base 81 used with a notebook computer or other
personal electronic device lock 80 which slides in from the
left so that one or more base pads 87 are retained by one or
more brackets 82 on base 81. Figures 13 and 14 also show a
clamp 86 which secures the lock in place by clamping the lock
over a working surface, such as a table top 85.

-'A "better view ot this is the side edge view of Figure
14. Clamp 86 slips over the edge of work surface 85. Locking
bar 84 is captive in left bracket of computer or other
personal electronic device lock 80, but it can swing out to
permit access of computer or other personal electronic device
display. The distal end 88 is grooved to accommodate a key
lock to secure the computer or other personal electronic
device as well as lock 80'to base 81. The long neck portion
of base 81 from clamp 86 to brackets 82 positions the
computer or other personal electronic device at a convenient
distance from the front edge of table working surface 85. The
detail of clamp 86 in Figure 13A shows how screw 92 with
optional security head 91 is screwed into the bottom surface
of table working surface 85 via pointed end 93.
Figure 13B shows how tang 97 prevents screw 91 from
being loosened when lock 95 is locked via key 96. Lock 95 can
be easily removed from hole 94 in lock bracket 90. When tang
97 is turned to position 98, screw head 91 is not obstructed
so that it can be removed or tightened.
Figure 15 is a top plan view showing details of notebook
computer or other personal electronic device lock 80 locked
to base 81 with a computer or other personal electronic
device display shown in dashed lines in position 117 and
keyboard shown in dashed lines in position 118. Power supply
box 100 can pivot open in the direction of arrow 101 on shaft
102 with a retaining cap; it is locked via tang 112. Notebook
computer or other personal electronic device lock 80 is slid
into a captive position within brackets 82 retaining the
edges of base plates 87 in the direction of arrow 104. The
left end of swinging locking bar 84 (which can swing out in
the direction of arrow 103) is retained via retaining cap 105
within slotted hole 115 and an oversize hole on front of the
left bracket. Key lock 110 grasps rod end 88 of swinging
CA 02566151 2006-11-08
WO 2005/111764 25 PCT/US2005/016487
locking bar 84, whfch maintains the security of the
assemblage via bracket tang 114, which is part of locking
base 81. Key 111 can be used to remove the lock body from the
end of swinging locking bar 84.
While Figure 13-15 shows a separate over the table
locking base 81 used with a notebook computer or other
personal electronic device lock 80 which slides in from the
left so that base pads 87 are retained by brackets 82 on base
81 of notebook computer or other personal electronic device
lock 80, it is contemplated that a further alternate
embodiment includes attaching notebook computer or other
personal electronic device lock 80 directly to a work surface
85, such as a study desk, by providing fastener receptacles
within base pads 87, wherein fasteners, such as screws or
bolts fasten base 81 directly to an upper side of the work
surface 85, without the use of over the table base 81.
Figure 16 shows another embodiment of a notebook
computer or other personal electronic device lock 130 with a
telescoping width adjusting feature to accommodate computer
or other personal electronic devices of varying widths more
securely. Base pads 136 are compatible with the use of
locking base 81 of the previous embodiment to retain this
continuous adjustment feature. Locking bar portions 137 and
138 are adjustable in size.
For example, as in Figure 17, incrementally spaced
detents or pins and holes may be used to facilitate width
adjustment.
Alternatively, as in Figure 16, locking bar 137 may be
hollow and threaded with a coarse thread; it is captive
within left bracket 134 and slotted back hole 133. Right
section of locking bar 138 is screwed into portion 137 and
can be quickly length adjusted by twisting it clockwise or
counter-clockwise. Horizontal section 131 fits into section
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487

-132 in a telescopirng fashion. After the notebook or laptop
computer or other personal electronic device display is
placed between the spread-apart brackets, the brackets are
pushed against its sides and swinging locking bar portions
137 and 138 are adjusted accordingly to fit into holes in
right bracket 135 for locking.
Figure 17 shows a different width adjustable computer or
other personal electronic device lock 170 with a discrete
locking mechanism including pivoted flange 178 with peg 176
at its distal end. Flange 178 is pivoted on pivot 182, such
as a rivet, attached to outer telescoping member 132 of
notebook computer or other personal electronic device lock
170. When swung in the direction of arrow 179, flange 178
will force peg 176 through hole 175 in telescoping section
132 and further into one of the holes 180 in inner
telescoping member 171 when in positional registration.
Flange 178 is locked in position when hole 185 is in
positional registration with hole 184 and locking bar 173 end
139 is passed through both. The swinging locking bar includes
hollow side section 172 and inner, preferably solid, side
section 173, which is telescopic within outer hollow side
section 172.
Figure 18 shows another embodiment 150 of this invention
wherein the locking base has been integrated with the
notebook computer or other personal electronic device lock.
Clamp 153 locks onto work surface 85 as described in a
previous embodiment with a separate locking base 81 (see
Figures 13-14). Upright brackets 151 and 152 with bar 83
between capture the notebook computer or other personal
electronic device display which is then locked via swinging
locking bar 84 and a key lock (not shown).
A related embodiment in Figure 19 shows integrated
base/computer or other personal electronic device lock 160
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487

"which has one o"'f "mof'''"pivot points 164 and 166 (on base part
167). Link 165 now pivots in relation to clamp section 163
such that the notebook computer or other personal electronic
device lock 160 can be more conveniently positioned on work
surface 85.
In Figure 19, for example, clamp 163 is placed on the
edge to the side of computer or other personal electronic
device lock base 167 instead of directly in front of it as
would be necessary in the embodiment of Figure 18.
The preferred low profile locking base embodiment of
this invention for consumer use is detailed in Figures 20-27.
Figure 20 shows a low profile locking base 200 with
narrow base 202 and low rise back 201. It is screwed to work
surface 285 via fasteners, such as screws 203. Locking bar
284 with optional rubber or elastomer grommets 205 and
machined end 288 is used to lock the display of a notebook or
laptop computer or other personal electronic device (not
shown) to locking base 200. End 288 is passed through hole
204 and locked with pin lock 110. Key 111 is used to unlock
and remove the computer or other personal electronic device.
The preferred simpler method of use of a locking base is
not to screw it down as shown in Figure 20 but instead to
create a portable locking kit by adding a clamp 211 and cable
210 as shown in Figure 21.
Due to the low profile design with a narrow base, all
components of the portable kit conveniently fit into a
tubular carrying case (not shown).
Figure 21 also shows Clamp 211 having a fastener, such
as a screw subassembly, including screw 212 and short
container, such as a cylinder 216, with transverse cable
attachment hole 213. At the first end of cable 210 is a
ferrule 215 with a transverse hole. This fits through hole
213. The cable is threaded through hole 213 after clamp 211
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
28
is securea using tne appropriate tool to tighten screw 212.
The distal end of cable 210 has ferrule 214 with enlarged end
which does not fit through hole 213.
Figure 22 shows the arrangement more clearly. It is
noted that cylinder 216 has distal hole 220 which
accommodates the screw head and also has a screw clearance
hole 221 on its top surface. After cable 210 is threaded
through hole 213, a tool cannot reach screw head 222 to
loosen clamp 211 since access is denied through distal hole
220. After cable 210 is .installed through cylinder 216, the
end 288 of locking bar 284 is passed through the transverse
hole iri ferrule 215 prior to locking bar 284 to base 200.
In an alternate embodiment of the clamp screw
subassembly no tool is required to tighten or loosen clamp
211. For example, an exploded view of subassembly 230 is
shown in Figure 23 with end cap 231 pushed down over clamp
screw 233 and press fit into the end of knob 235. Optional
pins 238 can be driven radially to insure positive
attachment. Cap 231 has screw clearance hole 232 at its
center. Screw 233 becomes captive as a subassembly with tall
head 234 within knob 235 once cap 231 is attached. Offset
transverse hole 237 in knob 235 goes through both walls and
is sized for cable attachment.
Figure 24 shows the underside of cap 231 revealing
hexagonal recess 240 sized to engage bolt head 234.
Figure 25 is a top view of subassembly 230. In the side
crossection of Figure 26, bolt head 234 is seated in recess
240 of cap 231. This is prior to the insertion of cable 210
through holes 237. Clamp 211 can be tightened in this
depicted configuration by turning knob 235 since recess 240
acts as a socket wrench to bolt 233. It is noted also that
the size of head 234 interferes with the placement of hole

"2~"7"the'reby preventing insertion of cable 210 while head 234
is seated in recess 240.
If knob 235 is pushed up as shown in Figure 27, cable
210 can now be easily inserted through holes 237 adjacent to
screw 233 and spacing head 234 away from recess 240. In this
configuration with cable 210 installed through knob 235, if
turned, knob 235 will spin freely regardless of the up or
down forces exerted. Clamp 211 can only be removed after
cable 210 is removed and head 234 is re-seated in recess 240.
In lieu of a non-standard screw 233 with tall head 234, a
standard hex screw can be used with a nut screwed up against
the head and adhesively bonded as a unit. A washer between
the nut and the screw head would only enhance the operation
creating a more positive barrier with cable 210.
In an alternate protruding member locking embodiment of
this invention, spikes, security rods or strips are used to
secure a personal electronic device, such as a notebook
computer, cellphone, personal digital assistant (PDA) or
electronic music player (i.e. iPod ).
For example, in Figure 28, a notebook computer or other
personal electronic device with base 275 and display 276 is
shown. One of the three through-holes is required for this
embodiment. Hole 278 is at the hinge line, while hole 279 is
through the display housing; hole 277 is diagonally through
one of the front or rear corners of the base.
Figure 29 shows locking rod or spike 285 which is
inserted in any of the three hole locations discussed.
Ferrule 286 with a groove near its distal end is then
inserted through the transverse hole of spike 285 and locked
with pin lock 110. Ferrule 286 is securely attached to cable
210 which had been passed through knob 235 after clamp 211
had been tightened at the edge of a table or desk top. In
CA 02566151 2006-11-08
WO 2005/111764 PCT/US2005/016487
niariner'~" t5e"rt"i1lustrated notebook computer or other
personal electronic device is secured via a secure cable.
In a variation of this embodiment, the separate spike
285 is replaced by a captive security rod 291 as shown in
5 Figure 30. Note that rod 291 may be attached either to one
end of the hinge or alternatively to the top surface of the
base of computer or other personal electronic device 290 at
any convenient location where space permits. Rods 291 are
stored in a recessed position with only a small knob
10 protruding so that they may be easily grasped to unlock into
the extended position to expose a transverse hole. Ferrule
286 and lock 110 are then used in the same manner as with the
separate spike 285.
In another spike variation shown in Figure 31, long
15 spike 296 is used to secure computer or other personal
electronic device 294 which has a hole 295 through its base.
Hole 295 is placed over pre-existing hole 298 through table
top 293; then spike 296 is inserted such that transverse hole
297 is accessible beneath table top 293. Then transverse pin
20 299 with a groove adjacent its distal end is inserted through
hole 297 and locked with pin lock 110. Thus this variation
locks a notebook computer or other personal electronic device
using a spike without the aid of a cable.
In another embodiment shown in Figure 32 with a flexible
25 locking strip 301, a detail of notebook computer 304 with
display 305 and keyboard portion 306 is shown adjacent to
clamp 302. Flexible locking strip 301 is shown prior to
insertion through the hinge gap between display 305 and
keyboard 306 (not shown) and further between bottom jaw 314
30 and top movable jaw 312 of clamp 302.
In lieu of being inserted within a hinge gap, flexible
locking strip 301 may be inserted within a thin,

for rod 285 of Figure 29.
Figures 33, 36 and 37 show other features of clamp 302
with movable top 311 and stationary base 313. Locking strip
301 is clearly shown in top view and side view in Figures 34
and 35 respectively. Wedge stop 325 is shown at one the
proximal end with narrow rectangular strip 326 at the distal
end. Wedge stop 325 is preferably plastic which is bonded to
strip 326 as by overmolding. It is noted that base portion
313 of clamp 302 is typically screwed to work surface 303 via
screws 322, however, alternatively security cable 320 with
secured distal end (not shown) can be used.
Gripping means, such as serrations 337 in Figure 36,
form lower static jaw 314 of Figures 32 and 33; they engage
strip 301. Hole 336 is used for optional cable 320. Holes
322a accommodate fasteners 322, such as screws. Rectangular
holes 335 accept tabs 339 of upper movable jaw 311 to form a
hinge. The vertical wall 313a of base 313 can be
alternatively joined to movable section 311 via ordinary
hinges.
As in Figures 38 and 39, spring 319 tends to keep jaws
312 and 314 slightly apart unless lock 317 is locked via key
318. In that case if key 318 is rotated while moving member
311 is pressed down, lock tang 331 will engage lock recess
316 at the distal end of spring 319; recess 316 is attached
to base 313. This action will lock locking strip 301 between
jaws 312 and 314. Note that lock 317 is attached to hinged
part 311 via a fastener, such as lock nut 330.
Figures 40-43 show notebook computer 304, cellular phone
346, PDA 347 and personal DVD player 348 each with hinge gap
345. In addition, the entry path of locking strip 301 is
shown by arrows in Figure 40.

Figure 40 a'so s ows a further alternate embodiment
whereby the housing of notebook computer 304 contains a slot
326 for insertion of a flexible or rigid locking strip 328
therethrough.
Figures 44-47 relate to an alternate embodiment of clamp
355 which incorporates a leaf spring 358 to impart locking
force to locking strip 301 when shackle 366 of padlock 365 is
passed through lock loops 362 and handle loop 376 (as in Fig.
46). In this embodiment, shallow recess 359 with transverse
serrations aggressively grasps strip end 326 under bending
force of spring 358, which itself can have optional
transverse serrations on its contact surface.
When handle 357 is free to swing up, strip end 326 can
be easily passed between brackets 371 which are spaced apart
a distance "W" (as in Figure 45) to accommodate the width of
strip end 326. Base 356 is secured to work surface 303 via
fasteners, such as screws 369, which are passed through
countersink holes 367 (as in Figure 45). Leaf spring 358 is
swaged or brazed at region 363 within slot 373 of handle 357.
Hole 375 in loop 376 accommodates shackle 366. It is noted
that spring 358 has to be bent somewhat for handle 357 to be
in registration with the holes in padlock brackets 362. This
bending also permits clamp 355 to accommodate strip ends 326
of varying thicknesses. Also, with respect to the geometry of
spring 358 in Figure 44, if a pulling force is placed on
locking strip 301, frictional forces will tend to rotate the
free end of spring 358 in a counter-clockwise direction
thereby increasing clamping force on strip end 326; this
further counteracts the pull-out force. Since spring 358 is
wider than handle 357 (as in Figure 47), centering washers
377 are used on either side of it to increase the combined
width to X which is just slightly smaller than W. Rivet 360

in oracxets stDl acts as an axle for handle 357; hole 372 is a
clearance fit for rivet 360.
Figure 48 illustrates alternate embodiment locking strip
390 with locking wedge 391, strip 393 and end hole 392.
Locking strip 390 may be rigid or flexible.
Dashed lines 305 of Figure 48 show the position of a
computer display if this is being secured. Added hole 392
permits at least three non-clamp locking methods to be used.
These are illustrated in Figures 49-51; for clarity, no item
is shown being locked in these Figures 49-51.
It is understood that instead of being inserted through
a hinge gap, locking strip 390 may be first passed through a
thin, longitudinally extending slot in the housing of the
personal electronic device, such as a notebook computer,
instead of a round hole provided for a rod285 or 296, as is
shown in Figures 29-31. In this case, the thinness of the
slot 327 for 'strip 328 minimizes any intrusion into the
interior of the walls of the personal electronic device, such
as a notebook computer 305 and the like, with its intricate
wiring located in a tight space within the walls of the
notebook computer 305, or other personal electronic device.
The strip 390 may be a rigid rectangle or other
geometric shape. Additionally strip 390 may be flexible. If
flexible, strip 390 may pass through a slot in the housing of
the personal electronic device, or if the device is hinged,
through a hinge gap between the display of the device and the
main body of the device being secured.
In Figure 49, stud 395 is attached to and protrudes from
work surface 303. Hole 392 is simply passed over the distal
end of stud 395 and then the shackle of padlock 397 is passed
through the transverse hole in stud 395 to lock strip 390.
In Figure 50, secure cable 400 with collar 402 and a
rigid stud at its distal end is used to secure strip 390.

A.tter tne rlgia stuca. is passed through hole 392, cable lock
401-is snapped over the end of the stud thereby securing
strip 390.
In Figure 51, free cable 405 with lock member 406
permanently attached is passed through hole 392. Since member
406 is a bulge larger than the diameter of hole 392, locking
strip 390 will be secured when the distal end of cable 405 is
looped or otherwise secured to work surface 303 or to some
point adjacent to it.
In the foregoing description, certain terms and visual
depictions are used to illustrate the preferred embodiment.
However, no unnecessary limitations are to be construed by
the terms used or illustrations depicted, beyond what is
shown in the prior art, since the terms and illustrations are
exemplary only, and are not meant to limit the scope of the
present invention.
It is further known that other modifications may be made
to the present invention, without departing the scope of the
invention.
