Description
SPECIFICATION
A window guard
This invention relates to a window guard.
According to the present invention there is provided a window guard comprising a generally rectangular assembly of pivotally interconnected rods, first means for fixing one side of the assembly to one side of a window frame, and second means for releasably locking the opposite side of the assembly relative to the opposite side of the window frame, the assembly being collapsible in the direction substantially normal to the said opposite sides thereof.
Preferably, the first means comprises an elongate side member which extends along the said one side of the assembly and means for securing the side member to the said one side of the window frame, and the second means comprises an elongate locking member which extends along the said opposite side of the assembly and a latch carried by the locking member for locking engagement with a cooperating element attached directly or indirectly to the said opposite side of the window frame, at least selected ones of the ends of the rods at either side of the assembly being pivotally connected to the associated elongate side or locking member with sufficient freedom of movement longitudinally thereof to permit movement of the assembly between expanded and collapsed conditions.
The cooperating element may be fixed directly to the opposite side of the window frame. However, for wide windows it is preferred that the window guard further includes a second generally rectangular assembly of pivotally interconnected rods with means for fixing one side of the second assembly to the said opposite side of the window frame and having a further elongate member extending along the opposite side of the second assembly, the assembly being collapsible in the direction substantially normal to the said opposite sides thereof whereby the first and second assemblies
may be drawn together substantially into abutment
in the manner of a pair of curtains, and wherein the further elongate member constitutes the
cooperating element adapted for locking
engagement by the latch to the locking member of the first assembly, the window guard further
including locating means for defining the abutting
positions of the locking member of the first
assembly and the cooperating element of the
second assembly relative to the window frame.

Referring now to Figures 1 to 8 of the drawings, wherein similar numerals have been used to indicate like parts, there is shown therein a window guard generally indicated at 1. The window guard 1 comprises a generally rectangular collapsible assembly 2 consisting of a plurality of criss-crossing rods 3a-3j and 4a-4j pivotally interconnected in conventional manner at overlapping locations 5.
The collapsible assembly 2 is such that in its collapsed condition the rods 3a-3j and 4a4j reside in side-by-side relation, whereas in an expanded condition of the collapsible assembly 2 (not shown) the rods 3a-3j and 4a-4j define a plurality of quadrangles 6. The direction of expansion and collapse is substantially normal to the opposite sides 7 and 14 of the assembly, i.e.
horizontally as seen in Figures 1 and 8.
The collapsible assembly 2 is attached along one side7 to a substantially 'U' shaped side member 8 which embraces the ends of the rods at the side 7.
The side member 8 includes a pair of spaced apart legs 9 joined by a bridging portion or base 10. The base 10 has two pairs of brackets 11, each one of each pair having an aperture 11a for receiving screws (not shown) to fix the side member 8 to one side 12 of a window frame 13. The other side 14 of the collapsible frame 2 is similarly attached to a substantially 'U' shaped locking member 15. The side 14 of the collapsible frame 2 is fixed to the locking member 15 at a pair of end fixing points 16, and a central fixing point 17 intermediate the end fixing points 16. For the purpose of clarity the construction of only one of the end fixing points 16 and the central fixing point 17 will be described.
Furthermore, it will be understood that the side member 8 is attached to the side 7 of the collapsible frame 2 in a similar manner to that of the locking member 15 to the side 14.
The ends 18, 19 of the criss-crossing rods 3i and 4i respectively, overlap at the centre fixing point 17 (Figure 5) between the legs 20, 21 of the locking member 15. The ends 18, 19 are pivotally secured together and to the member 15 in conventional manner by means of a bolt 22 which projects through the legs 20, 21 of the locking member 15. A bushing 23 is mounted on the bolt 22 between the leg 21 and the rod 4i, and serves to hold the ends 18,
19 of the rods 3i and 4i in side-by-side relation.
The ends 24, 25 of the criss-crossing rods 3h and 4j respectively, overlap at the end fixing point 16 (Figure 6) between the legs 20, 21 of the locking member 15. The ends 24, 25 of the rods 3h and 4j are secured together in a similar manner as the ends 18, 19 of the rods 3jand 4j, by means of a bolt also enumerated 22. However, the legs 20,21 of the locking member 15 include an elongate slot 26, disposed in the region of the end fixing point 16, which allows the bolt 22 a certain amount of movement longitudinally of the member 15 which is necessary to permit the collapsible assembly 2 to be collapsed and expanded.
The base 27 of the locking member 15 includes a pair of spaced apart outwardly projecting lugs 28.
Furthermore, the locking member 15 includes a conventional manually operated latch 29 (Figure 7) to be described below, by which the locking member 15 may be locked to a cooperating side element 30 which is fixed to the side 31 of the window frame 13. The latch 29 is pivotally mounted on the bolt 22 at the central fixing point 17. The latch 29 includes a latch member32 pivotally mounted on the bolt 22 between the legs 20,21 of the member 15 and which has fixed thereto in conventional manner a pair of rods 33,34 which extend in opposite directions but parallel to the locking member 15.
The side element 30 includes a base 37 and a pair of legs 38 each of which has a pair of brackets 39. Each bracket 39 has an aperture 40 for receiving a screw (not shown) by which the side element 30 is secured to the side 31 of the window frame 13. The base 37 of the side element 30 and the base 27 of the locking member 15 have similar coincidental apertures 41, 42 respectively. Thus, as shown in Figure 7, when the locking member 15 is moved to the right hand side so that its base 27 contacts the base 37 of the side element 30, the apertures 41, 42 coincide so that the latch member 32 can be moved from the retracted position shown in solid lines in Figure 7 to the extended position shown in dotted outline, in which a lip 43 on the latch member 32 serves to hold the locking member 15 and the side element 30 together.Furthermore, each of the outwardly projecting lugs 28 on the base 27 of the locking member 15 engage in respective apertures 44 in the base 37 of the side element 30. Also, when the latch member 32 is pivotted from the position shown in
Figure 7 to the position shown in dotted outline, the rods 33,34 move upwards and downwards respectively so that the ends (not shown) of the rods 33,34 engage with brackets (not shown) in the top and bottom surfaces 35,36 respectively of the window frame 13. The latch member 32 has a handle (not shown) which projects through the leg 21 so that the latch member 32 is readily operated.
In use, the window guard 1 may be located as shown in Figure 8, so that the collapsible assembly 2 extends across the window on the inside of the window frame 13 of for example a home. When the locking member 15 is engaged with and locked to the cooperating side element 30 as hereinbefore described, the window is secured against burglars.
In particular, the handle for operating the latch member 29 and operating the rods 33,34 may include a suitable key lock, so that even if the window is broken it would be extremely difficult for a person to tamper with the lock by putting a hand through the spaces between the rods of the
collapsible assembly 2. When the home is occupied the locking member 15 may be released from the side element 30 and the collapsible assembly 2 may be compressed between the side element 8 and the
locking member 15 to permit the windows to be
opened. In this condition the rods 3a-3jand 4a-4j of the collapsible assembly 2 reside in side-by-side
relationship.
In another embodiment of the invention a side
element 30 as hereinbefore described may be
located centrally in a window frame so that a pair of
window guards, as hereinbefore described, secured
one at each side of the window frame, may be both
locked to the centrally mounted "side element". In this case however it is necessary that the centrally
mounted "side element" is suitably adapted to
enable the locking member of each of the window
guards to be locked to the centrally mounted "side element". Furthermore, it is necessary to mount a
pair of brackets (not shown) to both the top and
bottom surface of the window frame, so that the operating rods of the latch of each re.spective
locking member can be secured at the middle of the window frame.This embodiment of the invention will be particularly advantageous where it is desired to secure a particularly wide window.
The embodiment shown in Figure 9 differs from that shown previously primarily in that the side member 8 is not screwed to the window frame by external brackets 11 (Figure 2a), but instead is screwed to the window frame from inside. For this purpose apertures are provided in the base 10 of the member 8; however, these screw holes are not seen in Figure 9 as they are obscured by rollers 50 carried on the bolts 22. The arrangement is such that when the assembly is moved into its expanded condition the inward longitudinal movement of the bolts 22 in the slots 26 causes the rollers 50 to cover the screws so that they are substantially inaccessible and cannot be removed, thereby providing an additional safety factor against unauthorised entry.However, when the assembly is collapsed the outward movement of the rollers 50 relative to the member 8 exposes the screw holes which permits initial assembly of the guard and, if desired, removal.
It will also be seen that the side element 30 has been removed and replaced by simple plates 51, 52 and 53 screwed directly to the window frame.
Nevertheless, these cooperate with the latch 29 and lugs 28 in precisely the same way as the element 30.
It will be noted that in this embodiment the lockable handle 54 with keyhole 55 is shown.
Finally, a roller (not shown) is provided inside the locking member 15 at the base thereof at the position indicated by arrow 56, which roller supports the member 15 during expansion and compression of the assembly 2 to prevent damage to the window frame.
Referring now to Figures 10 and 11, an embodiment is shown which uses two assemblies 2 and 2'. The right hand assembly 2 is identical to that shown in Figure 9. The left hand assembly 2' is substantially a mirror image of the assembly 2, being affixed to the opposite side of the window frame by a member 8 in the same way as previously described, the only difference being that the locking member 15 is replaced by an elongate U-shaped member 60. This latter member 60 is attached to the right hand side of the assembly 2' in the same way as described for either of members 8 and 15 of the assembly 2, but is formed with apertures 41 and 44 in the same way as the side element 30 (Figures 1 to 8) or the plates 51 to 53 (Figure 9). Thus the locking member 15 can be locked to this member 60 in just the same way as previously described for the member 30.
The arrangement therefore permits the two assemblies 2 and 2', fixed at their distant ends to opposite sides of the window frame, to be drawn together in the manner of a pair of curtains, and locked together in the middle with the members 15 and 60 in abutment. In order to define the "closed" position of the assemblies, a pair of locating members 61 are screwed to the top and bottom of the window frame. These members 61 are divided by a transverse partition 62 into two opposite compartments 63 and 64 which receive the ends of the members 15 and 60 respectively when the members 15 and 60 are brought into abutment. It will be appreciated that without these locating members 61 the assemblies would have no clearly defined locking position and would tend to flop about.
