CABINET HAVING A LOCK ASSEMBLY
BACKGROUND OF THE INVENTION
The ~present invention relates generally to cabinets and more particularly to
lockable
cabinets.
Devices for dispensing articles are well known and widely used in commerce.
Such
devices are commonly used to dispense tickets, such as lottery tickets, and/or
cards, such as phone
cards.
In U.S. Patent No. 5,753,897 to K.J. Kasper, there is disclosed an apparatus
for dispensing
articles such as tickets and cards which includes a cabinet and a plurality of
article dispensing
assemblies inside the cabinet. Each article dispensing assembly includes a
base and a frame for
enclosing the articles to be dispensed in a stack. The bases are mounted on a
pair of vertical
support plates. A gate is disposed behind each frame for receiving articles
from its associated
frame and allowing only one article at a time to pass through. A toothed blade
is disposed
underneath each frame and a motor driven rack and pinion is coupled to the
toothed blade for
bringing the toothed blade into engagement with the lowermost article in the
stack, moving said
toothed blade so that the lowermost article is transported from the stack into
the gate, bringing the
1
CA 02330399 2001-01-09
toothed blade out of engagement with the article and then moving the toothed
blade back to engage
the next article in the stack. In one embodiment of the invention each frame
is hingedly mounted
on its base. In another embodiment of the invention each frame is hingedly and
lockably mounted
on its base and in still another embodiment of the invention, which is
intended especially for use
with cards which include an integrated circuit chip onto which information can
be written into and
read off of, each article dispensing assembly includes a read/write head
assembly underneath its
frame for reading information off of the chip on the card at the bottom of the
stack and/or writing
information onto the chip on the card at the bottom of the stack.
Devices for dispensing articles of the type described above are often housed
within a
security cabinet to prevent theft and/or tampering of the articles to be
dispensed thereby.
Security cabinets used to house article dispensing devices are commonly
equipped with a
lock assembly for locking the door of the cabinet in a closed position,
thereby precluding the
cabinet from being opened by unauthorized personnel, which is highly
desirable. Typically, the
lock assembly requires a unique key to be used to unlock the security cabinet.
One type of lock assembly which is well known and widely used in the art
utilizes a double
lock type arrangement. Specifically, the lock assembly comprises a key
operated plug which is
removably mounted in a shell. The lock assembly also comprises an attachment
device, such as
a bolt or screw, which is positioned behind and spaced apart from the shell,
the attachment device
being mounted on some type of plate. In the operation of such a lock assembly,
the plug is first
removed using a unique security key. After the plug has been removed, a
screwdriver or wrench
is then inserted through the bore in the shell and is used to unscrew the
attachment device. Once
the attachment device has been unscrewed, the door can be opened.

CA 02330399 2001-01-09
Lock assemblies of the type described above are well known in the art and are
widely used
in high security applications. In particular, lock assemblies of the type
described above are
commonly used in vending machines, currency changers, automatic bank tellers
or any other
similar application where it is desirable to lock the access door of a
cabinet, box or other similar
device.
Although well known and widely used in commerce, lock assemblies of the type
described
above suffer a couple notable drawbacks.
As a first drawback, lock assemblies of the type described above are time
consuming and
labor intensive to use. Specifically, it has been found that the secondary
unlocking process in
which a screwdriver or wrench is inserted through the bore in the shell and is
used to unscrew the
attachment device is tnne consuming and difficult to perform.
As a second drawback, lock assemblies of the type described above are
relatively insecure.
Specifically, it has been found that the secondary unlocking process in which
the attachment device
unscrewed can be accomplished using any conventional screwdriver or wrench. As
a
consequence, once the plug has been removed from the shell, any unauthorized
person can use a
screwdriver or wrench to access the items contained within the cabinet.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the drawings, and first to Fig. 1, there is shown a lock
assembly
constructed according to the teachings of the present invention, the lock
assembly being
represented generally by reference numeral 11.
Lock assembly 11 includes a lock 13, a key 15 and a tool 17.
Lock 13, which is also shown in section view in assembled form in Fig. 1(a),
includes a
shell 19, a nut 21, a key operated plug 23 and a cam module 25. Cam module 25
is also shown
in exploded perspective view in Fig. 1(b).
Key 15 is used as a primary locking device to rotate plug 23 in shell 19
between a locked
position in which plug 23 cannot be removed from shell 19 and an unlocked
position in which plug
23 can be removed from shell 19. Tool 17 is used as a secondary locking device
to rotate cam
module 25 relative to shell 19 for a purpose to be subsequently explained.
Shell 19 is a generally cylindrical member having a front end 27, an
externally threaded
main body portion 28, a rear end 29 which includes a lateral slot 30, a
central bore 31 extending
from front end 27 to rear end 29 and an internal groove 32 on central bore 31
at rear end 29.
Nut 21 is sized to screw onto main body portion 28 of shell 19 and is used to
secure shell
19 to the wall of a cabinet on which it is to be mounted, as will hereinafter
be explained.
Plug 23 is a generally cylindrically shaped member having a generally
rectangular shaped
front end 33 which includes a pair of ridges 34 and 35, a rear end 36, a main
body portion 37, and
a keyway 38, keyway 38 extending from one end of plug 23 to the other. Plug 23
is sized and
shaped so that it can be axially aligned and rotatably and removably disposed
in bore 31 of shell
19. Front end 33 of plug 23 is sized so that it can extend up into lateral
slot 30 in shell 19.
9
CA 02330399 2001-01-09
Plug 23 is disposed into shell 19 in the following manner. First, key 15 is
inserted into keyway 38. Then, plug 23 is pushed into bore 31 in shell 19
until surface
36-1 of rear end 36 abuts against surface 27-1 on front end 27 of shell 19.
When so
positioned, front end 33 will be disposed in slot 30 of shell 19 and ridge 35
will be
aligned with internal groove 32. Plug 19 can then be rotated 90 degrees using
key 15
until ridge 35 is disposed within groove 32, thereby locking plug 23 inside
shell 19. Key
15 can then be removed with plug 23 lockably disposed within shell 19. In
order to
unlock and remove plug 23 from shell 19, the procedure is reversed. It should
be noted
that key 15 cannot be withdrawn from plug 23 unless plug 23 is locked in shell
19.
Plug 23 and key 15 may be a plug, key combination such as shown in U.S. Patent
No.
4,635,455.
Cam module 25 includes a cam module base 39, a cam module bracket 41, a cam
module:
cover plate 43, a pair of pins 45 and 47, a pair of springs 49 and 51, a pair
of bolts 53. and 55, a
bearing 57 and a washer 59.
Bracket 41 has a main body portion 41-1 and a pair of feet 42.
Tool 17 has a front end 60 having a pair of ridges 60-1 and 60-2, a main body
portion 60-3
and a handle 60-4 which includes a body 60-5 and a bar 60-6.
Cam module base 39 is rotatably and slidably mounted on front end 30 of shell
19 and
includes a lateral slot 61. Pins 45 and 47 are fixedly mounted on cam module
cover plate 43
which is fixedly attached to cam module base 39 by bolts 53 and 55. Bracket 41
is seated on pins
45 and 47 and is slidably movable in slot 61. Springs 49 and 51 on pins 45 and
47 urge bracket
41 backward so that feet 42 project out of slot 61 beyond surface 62 on module
39, as shown in
Fig. 1. A stop 63 on base 39 limits slidable movement of base 39 on front end
29 of shell 19.
CA 02330399 2001-01-09
As long as feet 42 of bracket 41 extend out of slot 61 beyond surface 62 of
base 39, cam module
25 cannot be rotated relative to she1119. However, tool 17 is sized so that
when it is inserted into
and through shell 19 it will hit up against bracket 41 and, then, when tool 17
is pushed in further
it will push bracket 41 back against the action of springs 49 and 51 so that
feet 42 do not project
up outside slot 61 beyond surface 62. When bracket 41 is so positioned, cam
module. 25 can be
easily rotated relative to shell 19 by simply turni.ng tool 17.
As can be seen in Fig. 5(a), the front end 60 of tool 17 is longer than the
front end 33 of
plug 23, while the front body portion 60-3 of tool 17 is identical to main
body portion 37 of plug
23. Consequently, when plug 23 is inserted in shell 19, front end 33 will not
hit up against
bracket 41 thus tool 17 is the only way bracket 41 can be pushed back so that
cam module can be
rotated.
Referring now to Figs. 2 and 3, there is shown a first embodiment of a cabinet
constructed
according to the teachings of the present invention, the cabinet being
represented generally by
reference numeral 69. As can be appreciated, cabinet 69 is designed to enable
objects, such as
a card dispensing apparatus, to be lockably disposed therewithin for security
purposes.
Cabinet 69 is a generally hollowed out, rectangular member constructed of a
rigid and
durable material, such as steel. Cabinet 69 comprises a top panel 70, a pair
of side panels 71 and
72 , a rear panel'73, an interior base pane174 and a door 75. Top pane170,
side panels 71 and
72, rear pane173, interior base panel 74 and door 75 together defme an
interior cavity 76 which
is sized and shaped to house the desired object. A horizontal platform 77 is
shown mounted onto
side panels 71 and 72 in interior cavity 76. However, it is to be understood
that platform 77 is
11
CA 02330399 2001-01-09
not essential to the construction of cabinet 69 and as a consequence could be
removed therefrom
without departing from the spirit of the present invention.
Door 75 is a generally rectangular member and comprises an interior surface 75-
1, an
exterior surface 75-2, a first side edge 75-3 which is generally L-shaped in
configuration and a
second side edge 75-4 which is generally U-shaped in configuration. First side
edge 75-3 of door
75 is pivotally mounted onto side panel 72 by a hinge assembly 78. As will be
described further
in detail below, door 75 is capable of rotation between a closed position, as
shown in Fig. 2, and
an open position, as shown in Fig. 3. In addition, as will be described
further in detail below,
door 75 is capable of being locked in its closed position using lock assembly
11.
Referring now to Figs. 13-15, hinge assembly 78 comprises an elongated butt
hinge 79 and
an elongated bracket 80.
Butt hinge 79 is preferably constructed of a rigid and durable material and
comprises a first
leaf 79-1 and a second leaf 79-2. First and second leaves 79-1 and 79-2 are
generally rectangular
in shape and are capable of independent rotation about an elongated pivot bar
79-3.
Bracket 80 is preferably a hat section bracket constructed of a rigid and
durable material.
Specifically, bracket 80 preferably comprises a base 80-1 which is generally
rectangular. Bracket
80 also comprises first and second legs 80-2 and 80-3 which extend
orthogonally out from opposite
ends of base 80-1. Bracket 80 further comprises first and second flanges 80-4
and 80-5 which
extend orthogonally out from first and second legs 80-2 and 80-3,
respectively, in opposite
directions away from one another.
First flange 80-4 of bracket 80 is fixedly mounted onto an interior surface 72-
1 of side
panel 72 by any suitable means, such as by an adhesive or through welding.
Additionally, second
12
CA 02330399 2001-01-09
flange 80-5 of bracket 80 is fixedly mounted onto first leaf 79-1 of butt
hinge 79 by any suitable
means, such as by an adhesive or through welding. Furthermore, second leaf 79-
2 of butt hinge
79 is fixedly mounted onto interior surface 75-1 of door 75 at first side edge
75-3 by any suitable
means, such as by an adhesive or through welding.
As such, door 75 is capable of rotation between its open position and its
closed position
in the following manner. With first leaf 79-1 of butt hinge 79 fixedly mounted
onto second flange
80-5 of bracket 80, second leaf 79-2 can be rotated about elongated pivot bar
79-3 until it is
substantially coplanar with first leaf 79-1. Positioning second leaf 79-2 at
approximately 180
degrees relative first leaf 79-1, in turn, disposes door 75 in its closed
position, as shown in Figs.
2, 13 and 14.
Rotation of door 75 in a clockwise direction, in turn, causes second leaf 79-2
to rotate in
a clockwise direction relative elongated pivot bar 79-3. Door 75 is capable of
clockwise rotation
for approximately 90 degrees until first side edge 75-3 of door 75 abuts
against second leg 80-3
of bracket 80, door 75 being considered in its open position with first side
edge 75-3 in abutment
against second leg 80-3, as shown in Fig. 15.
As a principal feature of the present invention, it should be noted that hinge
assembly 78
acts as a hidden hinge because it is disposed entirely within interior cavity
76 of cabinet 69. Due
to the hidden colistruction of hinge assembly 78, with door 751ocked in its
closed position, hinge
assembly 78 is inaccessible. Because hinge assembly 78 is inaccessible with
door 751ocked in its
closed position, hinge assembly 78 is incapable of being tampered or
manipulated, thereby
rendering cabinet 69 tamper proof, which is highly desirable.
13
CA 02330399 2001-01-09
Door 75 comprises a plurality of spaced apart latches 81. Each latch 81
comprises a hook
81-1 and a mounting plate 81-2, hook 81-1 being fixedly mounted onto its
associated mounting
plate 81-2 such as through welding. Hooks 81-1 are disposed to extend out
through slots 81-3
formed in second side edge 75-4 of door 75. Mounting plates 81-2 are fixedly
secured onto
interior 75-1 of second side edge 75-4 of door 75 by bolts 82.
As shown in Fig. 3, side panel 71 of cabinet 69 comprises an inwardly
protruding flange
71-1 having a plurality of spaced apart slots 71-2. As will be described
further in detail below,
each slot 71-2 is positioned to enable an associated hook 81-1 to project
therethrough when door
75 is in its closed position.
A first bracket 85 is fixedly mounted at one end 87 to cam module 25 by bolt
55 which
extends through bearing 57 which is seated in a hole 86 in bracket 85. The
other end 89 of
bracket 85 is pivotally attached by a bolt 90 to a leg 91 of a second bracket
93. Main body portion
95 of bracket 93 is fixedly attached by bolts 97 and 99 to a slidably mounted
elongated slide plate
101 having slots 102. Slide plate 101 is capable of being displaced between an
upward position,
in which door 75 is unlocked, and a downward position, in which door 75 is
locked. Specifically,
when door 75 is closed and unlocked, hooks 81-1 of latches 81 extend through
slots 71-2 in flange
71-1 and through slots 102 in slide plate 101, as shown in Fig. 11. When door
75 is closed and
locked, slide plate 101 is displaced downward so that hooks 81-1 of latches 81
are aligned against
slide plate 101 rather than slots 102, as shown in Fig. 11, hooks 81-1
abutting against slide plate
101 to prevent door 75 from being opened.
Shel119, as can be seen for example in Fig. 4, is fixedly disposed through a
hole provided
in side panel 71 and held securely in place by nut 21. Cam module 25 is
rotationally mounted on
14
CA 02330399 2001-01-09
a bracket 83 which, in turn, is fixedly secured to side panel 71 by any
suitable means, such as
welding. Bracket 83 is preferably a hat shaped bracket comprising a pair of
outer flanges 83-1
which are mounted onto side panel 71 and a center portion 83-2 rides in a
groove 25-1 formed in
cam module 25 so that bracket 83 does not interfere with rotational movement
of cam module 25
relative to shell 19 when tool 17 is turned.
When too117 is initially inserted through shell 19 and into cam module 25 but
not turned
and door 75 is closed, cam module 25, bracket 85 and slide plate 101 will be
as shown in Figs.
9 and 11, with slide plate 101 in a lowered position so as to prevent door 75
from opening.
However, when tool 17 is rotated 180 degrees, tool 17, in turn, rotates cam
module 25 180
degrees about its axis. Rotation of cam module 25 180 degrees moves bracket 85
upward which,
in turn, displaces slide plate 101 to a raised position so that latches 81 are
aligned with slots 102,
thereby enabling door 75 to be opened.
It should be noted that cabinet 69 is highly effective in providing a secure
means for
housing a device. However, it has been found that the ease in placing such a
device within cabinet
69 can be difficult at times because door 75 can be opened only approximately
90 degrees.
Accordingly, referring now to Figs. 16-19, there is shown a second embodiment
of a
cabinet constructed according to the teachings of the present invention, the
cabinet being
represented generally by reference numeral 111. As can be appreciated, cabinet
111 is similarly
designed to enable objects, such as a card dispensing apparatus, to be
lockably disposed
therewithin for security purposes.
Cabinet 111 differs from cabinet 69 only in that cabinet 111 comprises a hinge
assembly
113 for pivotally mounting first side edge 75-3 of door 75 onto side pane172
which differs slightly
CA 02330399 2001-01-09
in construction from hinge assembly 78. As well be described further in detail
below,
hinge assembly 113 enables door 75 to be opened approximately 180 degrees,
which
is highly desirable in certain applications.
Referring now to Figs. 17-19, hinge assembly 113 comprises elongated butt
hinge 79 and
an elongated bracket 115. As can be appreciated, hinge assembly 113 differs
from hinge assembly
78 only in that elongated bracket 115 differs in construction from elongated
bracket 80.
Specifically, bracket 115 is preferably constructed of a rigid and durable
material. Bracket
115 comprises a base 115-1 which is generally rectangular. Bracket 115 also
comprises first and
second legs 115-2 and 115-3 which extend orthogonally out from opposite ends
of base 115-1.
Bracket 115 further comprises first flange 115-4 which extends orthogonally
out from first leg
115-2 in the direction away from second leg 115-3. In addition, bracket 115
comprises a second
flange 115-5 which extends orthogonally out from second leg 115-3 in the
direction towards first
leg 115-2.
First flange 115-4 of bracket 115 is fixedly mounted onto an interior surface
72-1 of side
pane172 by any suitable means, such as by an adhesive or through welding.
Additionally, second
flange 115-5 of bracket 115 is fixedly mounted onto first leaf 79-1 of butt
hinge 79 by any suitable
means, such as by an adhesive or through welding. Furthermore, second leaf 79-
2 of butt hinge
79 is fixedly mounted onto interior surface 75-1 of door 75 at first side edge
75-3 by any suitable
means, such as by an adhesive or through welding.
As a principal feature of the present invention, it should be noted that due
to the
lengthening of base 115-1 and the inward extension of second flange 115-2,
door 75 is
capable of being opened approximately 180 degrees. Specifically, door 75 is
capable
of rotation between a closed position
16
