WINDOW OR DOOR LOCK SYSTEM
FIELD OF THE INVENTION
The present invention relates to a window or door
assembly which includes a lock system for locking the
window or door of the assembly.
BACKGROUND OF THE INVENTION
Over the last few years significant developments
have been made with respect to the window and door
industry. Many of the new windows and doors include the
most up to date hardware for opening and closing the
window or door and for locking the window or door. The
locking hardware is particularly important due to a
number of increasing incidents of break-ins and
burglaries. Often time's more than one lock on a window
or door is desired to ensure the integrity of the window
or door. When more than one lock is used on a window or
door it becomes difficult to determine where the hardware
for operating the lock is to be appropriately located on
the window or door assembly. Furthermore, when numerous
locks are used traditional thinking results in a window
or door having a separate lock control for each lock.
This not only adds to the cost of the assembly but in
addition creates a very cluttered appearance. In
addition, in order to operate the locking system one must
remember to perform separate locking actions at each of
the lock regions.
SUMMARY OF THE PRESENT INVENTION
A window or door lock system of the present
invention comprises a frame mounted to a building and
including first and second side jambs. A frame closure

CA 02490658 2004-12-22
- 2 -
member i.e., a window or a door has a first side edge
which is pivotally mounted to the first side jamb of the
frame for opening and closing the closure member relative
to the frame. The closure member has a second side edge
which locates adjacent the second side jamb of the frame
when the closure member is closed.
The second side edge of the closure member
includes a first lock part. The second side jamb of the
frame includes a channel extending lengthwise of the
frame. The channel has a channel mouth along its length
facing interiorly of the frame. The channel also has
undercut channel regions to each side of the channel
mouth.
A slide bar is slideably fitted in the channel and
a second lock part is secured to the slide bar. The
second lock part protrudes through the mouth of the
channel.
When the closure member is closed with the frame
the slide bar slides the second lock part into and out of
locking engagement with the first lock part on the second
side edge of the closure member to either lock the
closure member with or to release the closure member from
the frame.
Using a construction as described immediately
above, more than one lock part may be provided on the
closure member and more than lock part may be provided on
the side bar. Regardless of the number of lock parts on
each of these components, a single sliding motion of the
slide bar allows the lock parts on the slide bar to slide
into and out of locking engagement with corresponding
lock parts on the closure member. As such, nothing more
than a single control for operating all of the locks is

required with the window or door lock system of the
present invention.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
EMBODIMENTS OF THE PRESENT INVENTION IN WHICH:
Figure 1 shows a window assembly generally
indicated at 1. This window assembly comprises a frame
generally indicated at 3 and a sash generally indicated
at 5. Frame 3 mounts in a building wall opening with the
sash in turn being mounted to the frame.
The key to the present invention relates to the
inclusion of a lock system within window assembly 3.
This lock system is to be described later in detail.
However, before going into the specifics of the lock
system it is to be understood that this same lock system
is equally as well used in a door assembly comprising a
door mounting frame and a door mounted to that frame.
Returning to Figure 1 of the drawings, frame 3
comprises a header 7 a sill 9 and first and second side
jambs 11 and 11 respectively.
All of the above describes frame pieces are
preferably made from a vinyl extrusion. Each of the
pieces is preferably cut from a common length of
extrusion and then cut to desired sizes to make the
header jambs and sill of the frame.
Turning to Figure 2 of the drawings, a key
component of the vinyl extrusion of side jamb 13 is a
channel forming piece generally indicated at 15. This
channel forming piece includes an internal hollow 17 with
a channel mouth 19 opening interiorly of the window
frame. Channel mouth 19 extends the full height of
channel piece 15.

CA 02490658 2004-12-22
- 5 -
Provided to opposite sides of channel piece 15 are
a pair of mouth bordering legs 21. These legs define
undercut regions 23 along the length of the opening 17
within channel piece 15.
Window sash 5 includes a first sash jamb 55 and a
second sash jamb 57. Sash jamb 55 is pivotally mounted
to frame jamb 11 for opening and closing the sash
relative to the frame.
Sash jamb 57 when the window is closed fits inside
of frame jamb 13. As best seen in Figure 5 of the
drawings channel forming piece 15 has a front face 17.
Face 17 provides a stop for the sash jamb 5 when the
window is closed.
Before the window is assembled to its Figures 1
configuration e.g., before the Figure 7 is fitted to the
frame a slide bar generally indicated at 31 is located
within channel 17. The actual bar portion of slide bar
31 is wider than the channel mouth 19 such that the
opposite edges 34 of bar 33 locate within the undercut
regions 23 of the channel opening. This prevents the bar
from pulling outwardly through the mouth of the channel.
Fitted to bar portion 33 are a plurality of studs
generally indicated at 37. These studs include a
cylindrical body portion 43 having a head 39 which fits
into any one of the circular openings 35 provided along
the length of bar portion 33. A larger collar 47 fits
over the cylindrical body portion 43 of each of the
studs. Collar 41 abuts with the flat side face of bar
portion 33.
The heads of the studs 37 may either be simply
held by a friction fit within the opening bar portion 33

CA 02490658 2004-12-22

or they may be additionally secured in place by some type
of bonding agent between the stud and the bar portion.
The studs at their spaced apart locations along
bar portion 33 are centered on the bar portion. The main
body portion 43 of each of the studs projects through the
channel mouth 19 interiorly of the window frame. The
collar portion 41 in each of the studs as well seen in
Figure 5 of the drawings is trapped against lateral
movement out of the channel opening by means of the
return legs 21 defining the undercut regions 23 in the
channel opening.
As it will be appreciated from the description
above control bar 31 with the studs mounted thereon is
slideable vertically of the frame jamb but cannot be
pulled out of the frame jamb once the frame has been
fully assembled.
It is be further noted from the description above
that because the channel mouth is open over the complete
length of the channel the control bar with its studs is
easily located within the frame jamb by simply sliding it
down into the frame jamb before the header has been put
into position. Once the header has been assembled with
the rest of the frame, it is not only the bar portion 33
but in addition the studs on the bar portion due to the
provision of their collars 41 which are trapped in the
channel cannot be pulled out of the channel.
Returning to Figure 1 it will be seen that sash
jamb 57 at the free or moveable edge of the sash is
provided on its interior surface with a plurality of lock
parts 59. Each one of these lock parts as better seen in
Figure 6 of the drawings includes a downwardly outwardly
free ended leg 61. Leg 61 when the sash is closed within

the frame locates to the inside of channel piece 15
sitting over the mouth of the channel.
Provided on frame jamb 13 is a lock control handle
generally indicated at 75. Frame jamb 13 includes an
inner return part generally indicated at 14 having a flat
face region 16. Face region 16 locates to the interior
of the building. A handle mount 77 secures to the face
16 of frame return 14. Pivotally mounted at 81 to mount
77 is a handle piece 79. Handle piece 79 is pivotally
secured at 85 to a lock connecting piece 83. The lock
connecting piece where pivotally secured to handle member
79 fits through a precut slot (not shown) in the frame
return 14. This allows the handle with its lock
connecting piece to attach by connector 87 to the bar
portion 33 of the slide bar. In the preferred embodiment
connector 87 comprises a cylindrical attachment that
press fits into one of the circular openings in bar 33.
Figure 6 of the drawings shows the handle member
79 of the control handle pushed upwardly. As a result of
its pivotal connection to mount 77 and the pivotal
connection with bar connecting member 83 the bar is
pulled downwardly in the Figure 6 position. The sash is
then closed with the window frame such that the arm 61 of
lock part 59 on sash jamb 57 locates above body portion
43 of stud 37 secured to the slide bar. Figure 6 shows
the sash moving to this position and the lower most lock
part on the sash. As will be readily understood the same
movement occurs at the two lock parts of the sash above
the one shown in Figure 6 of the drawings.
Once the lock parts 59 on the sash is located over
the channel mouth of the frame jamb handle member 79 of
control handle 75 is pushed downwardly to the Figure 7
position of the drawings. This pushes up on connector

~ ,. . , 1
CA 02490658 2004-12-22
piece 83 which forces the slide bar to slide upwardly
within the frame channel. Each of the three studs
mounted to the slide bar then slides up beneath the free
leg 61 of each of the lock parts 59 on the sash. The
sash is now fully locked with the frame.
As will be further understood from the description
above more studs may be provided on the slide bar and
more lock parts may be provided on the sash in
appropriately located positions for further enhancing the
locking action of the frame on the sash. In the
alternative, as few as a single stud and lock part may be
used to lock the sash closed with the frame.
In the embodiment as described when using two or
more different lock points between the sash and the frame
only a single control handle is needed to operate all of
those different lock points. Furthermore, if additional
lock points are needed as may be the case for a door
assembly where the height of the door is substantially
greater than the height of a window, the only thing that
needs to be added is additional studs and additional door
edge lock parts. The slide bar with the spaced holes
along the length thereof is already setup to receive
these additional studs. To further ease the assembly the
frame for receiving the slide bar includes its own slide
bar receiving pocket in the way of the elongated channel
extruded in the construction of the frame.
Although various preferred embodiments of the
present invention have been described in detail, it will
be appreciated by those skilled in the art that
variations may be made without departing from the spirit
of the invention or the scope of the appended claims.
