Abstract
Abstract:
A novel window security bar arrangement is described which is tamper-proof while also being easily openable by means of a lock in an emergency. It includes a plurality of tubular members telescopically associated to form a telescopic tubular assembly with a pair of outer ends.
One of said assembly outer ends is connected to a hinge plate of a first hinge assembly including a pair of hinge plates, the other of said plates having holes for receiving screws to mount the plate to a first side of a window frame. A second hinge assembly includes a pair of hinge plates and one of this second pair includes a projecting bracket adapted for locking connection to the other of said telescopic tubular assembly outer ends, while the other of said second pair of hinge plates has holes for receiving screws to mount the plate to a second side of a window frame. The hinge assemblies are arranged such that when the bracket is connected to the telescopic tubular assembly, the screw holes in one hinge plate of each pair are covered by the other hinge plate of each pair so that the mounting screws cannot be removed.

Description
Window security bar arrangement This invention relates to window security bar arrange-ments, particularly for basement windows.
Window security bar arrangements have been known since ancient times and were commonly used before there were organized police forces. With increasing break ins and violence today, they are again becoming an essential part of the house. They are particularly important on basement windows.
There are many prior patents to window security bar arrangements and one example that can be mentioned is McCormack, Canadian Patent 138,190 issued January 30, 1912. That patents shows a telescopic bar with pivotal end mountings.
One of the problems with security bars for basement windows is that what is effective for keeping people out of a house is also effective in keeping them in the house in an emergency situation such as a fire. Accordingly, it is essential that security bars be capable of being extrem-ely secure from the outside while being easily openable from the inside in an emergency. It is the object of the present invention to provide a security bar arrangement which meets the above requirements.
Thus, the security bar arrangement of the present invention is designed to be tamper-proof while also being easily openable by means of a lock in an emergency. It includes a plurality of tubular members telescopically associated to form a telescopic tubular assembly with a pair of outer endsO One of said assembly outer ends is ,~j3, ,'~: `'`~ ' connected to a hinge plate of a first hinge assembly including a pair of hinge plates, the other of said plates having holes for receiving screws to mount the plate to a first side of a window frame. A second hinge assembly includes a pair of hinge plates and one of this second pair includes a projecting bracket adapted for locking connection to the other of said telescopic tubular assembly outer ends, while the other of said second pair of hinge plates has holes for receiving screws to mount the plate to a second side of a window frame. The hinge assemblies are arranged such that when the bracket is connected to the telescopic tubular assembly, the screw holes in one hinge plate of each pair are covered by the other hinge plate of each pair so that the mounting screws cannot be removed.
A preferred embodiment of the invention is illustrated by the attached drawings in which:
Figure 1 i8 a side elevation of an installed security bar arrangement according to the invention;
Figure 2 is an isometric view of one hinge assembly;
and Figure 3 is an isometric view of the other hinge assembly.
As will be seen from the above drawings, the security bar arrangement includes a central metal tubular member 10 with a pair of inner slidable bars 11 and 12 telescoping out of the ends of tubular member 10. This tubular member 10 may conveniently include an interior central stop or abutment 31. This tubular member 10 may also have fixed thereto a variety of decorative metal strips, such as the 5C rolls 29.
As seen in Figure 3, the bar 11 is fixed at one end to a hinge assembly 13. This hinge assembly includes a pair of hinge plates 15 and 16 connected by a fixed pivot pin 35 19. The plate 16 has holes 17 for receiving mounting screws 30 while hinge plate 15 is connected to one end of .;
bar 11, e.g. by a weld connection 18. This hinge assembly 13 with the bar 11 connected thereto is mounted to one side of a window frame by means of the screws 30.
A second hinge assembly 14 is mounted to the opposite side of the frame. ThiS assembly, as shown in Figure 2, includes a pair of hinge plates 20 and 22 connected by a fixed pivot pin 25. The plate 20 has holes 21 for receiv-ing screws 30 and on the face of plate 22 is mounted a pro-jecting socket or bracket 23 with holes 24 in the project-ing portions. This socket may be a U-shaped bracket as shown, or it may be in the form of a tubular socket into which bar 12 slides.
The telescopic slide bar 12 has a hole 32 extending therethrough and this hole is arranged to align with the holes 24 of socket 23. A pin 26 then passes through these holes to fix the assembly together. The lower end of pin 26 has a transverse hole 28 to receive a padlock 27.
Alternatively, the bolt of a lock may pass directly through the holes 24 and 32, without the use of a separate pin.
There are several advantages to this system. Firstly, it is easily installable by a homeowner simply by using a screwdriver and some wood screws. It is installed in the same manner as any regular pair of hinges. This can con-veniently be done when the hinges are in the positions shown in Figures 2 and 3.
Then, when the assembly is placed in the lock position as shown in Figure 1, the wood screws are fully protected against tampering because plate 22 is flush against plate 20, thereby totally covering the heads of the screws in plate 20 and plate 15 is flush against plate 16, thereby covering the heads of the wood screws in plate 16.
Moreover, with the arrangement of end hinge assemblies and the lock 27, the security bar arrangement can easily be opened in an emergency. Thus, a key for the lock is kept in the basement of the house near the window where there is easy access to it from the inside but it cannot be reached from the outside.
It will be further understood that within the concept of the present invention, the locking arrangement of the end of sliding bar 12 to the hinge plate 22 can take any convenient form. Thus, there are many possibilities in terms of locking bolts, locking latches, etc., with either combination or key openings within the concept of this invention.
