Sept. 7, 1965 w. EDWARDS' REMOVABLE WINDOW GUARD Filed June 10, 1963 Flag INVENTOR WALLACE EDWARDS BY WWW ATTORNEYS.
United States Patent 3,204,981 REMOVABLE WINDOW GUARD Wallace Edwards, Ottawa, Ontario, Canada, assignor to The Waltham Holdings Limited, Ottawa, Ontario, Canada Filed June 10, 1963, Ser. No. 286,663 4 Claims. (Cl. 280-150) This invention relates to a window guard and more particularly a removable window guard for use in the window of a vehicle such as an automobile.
Guards and screens which are inserta'ble in the windows of automobiles are known. However, many of such devices impede or prevent the closing of the window after they have been inserted. Those devices which do not impede movement of the window pane depend for insertion on either movable o-r flexible fastening appurtenances which make the device easily removable and consequently ill-suited as a guard means.
The present invention overcomes these disadvantages by providing a device which, while being capable of positioning in the window in a simple manner, requires a degree of force to remove it. The degree of force will be of an order beyond the capability of a child to exert.
In its broadest aspect the invention consists of a window guard for removable positioning in a window frame and having a window panel slidable in a channel in the frame. The guard comprises a laterally rigid body portion resiliently depressable in a vertical direction on the application of external force, angled means integral with the lower edge of the body portion and adapted to engage the channel and rest on the frame, at least one projection integral with the upper edge of the body portion and adapted to seat in the channel, both the angled means and the projection being assoicated with the body portion in a manner permitting free slidable movement of the window panel when the guard is positioned in the frame. In a preferred embodiment of the invention the angled means may be L-shaped (which may be padded in its horizontal portion), the projections may be Z shaped lugs, and the body portion may comprise an elongated element to form upper and lower horizontal portions and indented side portions.
The invention will now be described with reference to the accompanying drawings which illustrate an example embodiment. In the drawings:
FIGURE 1 is a perspective view of the window guard positioned in a window frame;
FIGURE 2 is a cross-section taken along the line 22 of FIGURE 1; and
FIGURE 3 is a perspective view of the guard itself.
The guard comprises a main body portion 1 which in the illustrated embodiment is an elongated element of spring steel or other slightly elastic but form-retaining material which is bent into a configuration substantially blocking the window opening when the device is positioned in the window frame. The configuration has an upper horizontal section, or edge portion, 2, a lower horizontal section, or edge portion, 3, and two side sections 4 which are bent to form inwardly projecting U-shaped indentations 5, sections 4 and 5 forming resilient obstruction means.
The upper horizontal section 2 of the body portion 1 carries a pair of projections in the form of lugs 6 which are Z-shaped to provide an upper horizontal flange 7, an
3,204,981 Patented Sept. 7, 1965 upright flange 8, and a lower horizontal flange 9 fixed for instance by welding, to the horizontal section 2 of the body portion.
The lower horizontal section 3 of the body portion 1 carries angle means in the form of an L-shaped bracket 10 having a horizontal flange 11 and a thin vertical flange 12. The horizontal flange 11 preferably carries a lining 13 of cushioning material such as foam rubber and may be curved downwardly at its free edge 14.
The guard is inserted in a window frame 15 as shown in FIGURES 1 and 2. To insert the guard, flange 12 of bracket 10 is slipped into channel 21 of frame 15, between the inner portion 16 of frame 15 and glass window panel 17. With flange 11 resting on the upper edge of frame portion 16, the downward force is applied to the upper part of body portion 1 as indicated by arrow 18, for instance by gripping the indentations 5 and pulling downwardly. Being thus depressed, the guard is moved in the direction of arrow 19 as shown in FIGURE 2 so that lugs 6 pass beneath the inner part of upper portion 20 of frame 15. On release of the downward pressure the upper flanges 7 of lugs 6 slip into channel 21 of the window frame. In this position the guard is secured in the frame against lateral movement unless a considerable degree of downward force is applied to body portion 1 as explained above. The amount of downward force required to depress body portion 1 can be predetermined by .a suitable selection of material use-d in fabricating it. It will also be seen from FIGURE 2 that window panel 17 can be freely raised or lowered to a fully closed or opened position.
What I claim as my invention is:
1. A window guard for removable positioning in a window frame having .a window panel slidable in a channel in said frame, said guard comprising a body portion having a first edge portion, a second edge portion and a resilient obstruction means between and secured to said end portions, said obstruction means adapted to bias one end portion from the other; angled means integral with said first edge portion of said body portion and adapted to engage said channel and rest on said frame; at least one projection integral with the said second edge portion of said body portion and adapted to seat in said channel, said angled means and said projection being associated with said body portion in a manner permitting free slidable movement of said window panel when the guard is positioned in said frame.
2. A window guard as claimed in claim .1, said body portion being laterally rigid in said window frame, and depressible in a vertical direction upon the application of external force.
3. A window guard as claimed in claim 1 wherein the body portion comprises an elongated element bent to form the edge portions and indented obstruction means.
4. A window guard for removable positioning in a vehicle wind-ow frame having a glass panel slidable in a channel in said frame, said guard comprising a laterally rigid body portion resiliently depressable in a vertical direction upon the application of external force, said body portion being an elongated element bent to form upper and lower horizontal sections and indented side sections, an L-shaped bracket integral with the lower edge of said body portion and adapted to engage said channel and rest on said frame, at least one Z-shaped lug integral with the upper edge of said body portion and adapted to seat in 3 said channel, said bracket and said lugs being associated with said body portion in a manner permitting free slidable movement of said window panel when the guard is positioned in said frame.
