ATTORNEYS BACKGROUND OF THE INVENTION It is likely that in the event of serious accident involving the overturning of railroad trains, buses, and other like vehicles carrying passengers a number of windows of such vehicles will become shattered. In order to evacuate passengers from the interior of such damaged vehicles, it is often necessary to remove passengers through windows which contain fragments of glass within the frame or sash which of course is extremely hazardous. It is the purpose of the present application to construct a novel window frame or sash which in the event of the breakage of the glass pane readily permits piece-wise removal of the frame and broken glass fragments.
SUMMARY OF THE INVENTION In accordance with the present invention, there is provided a window frame or sash comprising a plurality of side pieces each being channeled to receive the edge portion of a window pane. Each side piece is equipped with a strip of hook and/or loop fastener material along its outside facing edge, the adjacent structure of the vehicle or bus being equipped with mating hook and/or loop fastener means. Each side piece is clipped to an adjacent piece at adjoining ends and is quickly disconne'ctable therefrom so that in the event of window pane breakage, each side piece can be stripped individually from the adjacent mounting structure.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view showing the pull-out window frame of the invention;
FIG. 2 is a fragmentary section taken in the direction of the arrow 2-2 of FIG. 1;
FIG. 3 is a fragmentary side elevation of a typical corner part of the window frame of FIG. 1;
FIG. 4 is a section taken in the direction of arrows 44 of FIG. 3;
FIG. 5 shows an alternate form of side piece for holding a window pane; and
FIG. 6 illustrates the separation which occurs between the side piece of the invention and the adjacent structure.
DESCRIPTION OF THE PREFERRED EMBOIDMENT Referring now to the drawing and initially to FIG. 1 thereof, a pull-out window frame 10 constructed according to the invention has been illustrated. The frame 10 consists of four side pieces 11 of extruded aluminumi Each side piece defines a channel I2. In theembodiment of FIG. I, the channel 12 receives a rubber liner 13 having a groove therein for the reception of an edge portion of a window pane 14.
The adjacent structure 15 which may be of a vehicle or building is provided with an L-shaped recess as shown. Within the recess and along the surface toward the exterior of the vehicle or building is secured a strip 16 of loop fastener material. Each sidepiece 11 has attached to its outward facing side a mating strip of hook fastener 17 which when the side piece 11 is pressedinto the recess within structure 15, will cause the side piece 11 to be securely held in place with respect tosuch adjacent structure.
The comers of each side piece 11 are mitered in the usual fashion and are held together by means of a spring clip 18 which is received within slots 19 in the exterior of each side piece 11 at their comers. Each side piece 11 has attached thereto a handle 20.
Aswill be seen with particular reference to FIGS. 1 and 6, in the event a window pane becomes shattered, each side piece I I can be readily pulled from its fastening within the adjacent structure 15 by first removing the clips 18 and by exerting an outward pulling force upon each handle 20. During this process as shown in FIG. 6 it is preferred to peel the side pieces 11 top to bottom or side to side, that is to say to progressively separate the hook and loop fastener elements 16 and 17. During such removal, it may be desirable to use a knife edge 21 to assist in separating the hooks and loops of the fastener elements 16 and 17.
FIG. 5 shows an alternate form of side piece 22 which is integrally molded of a suitable material such as rubber or other plastic material. The side pieces 22 directly receive a pane 23 within a peripheral groove provided for that purpose. Packing 24 helps cushion the edges of the window pane. A seal 25 prevents the passage of moisture between the side pieces 22 and the ad- 25 jacent structure 15'. Hook and loop fastener elements I6 and 17' are attached to the side pieces 22 and to the adjacent structure 15' in the same manner as has been described with respect to the embodiment of FIG. 1.
In accordance with the foregoing, the pull-out frame of the invention permits quick and easy piece-wise removal of the window pane in case of emergency where it is necessary to clear the window frame opening of broken glass. The window frame of the invention therefore should contribute to the safety of vehicles such as buses and trains and may also have application in the construction of buildings where it is desirable to be able to replace broken windows in a quick manner.
It will be understood that the above description has related to particular embodiments of the invention and is therefore merely representative. In order to appreciate fully the scope of the invention, reference should be made to the appended claims.
What is claimed is:
1. In a window sash wherein the edges of said sash are received within an L-shaped recess defined in an adjacent structure to present a flush surface with respect to said structure, the improvement wherein said sash is constructed and is secured within said recess for ready piecewise removal from said recess in the event that there is breakage of the window pane contained by said sash, said improvement comprising said sash consisting of separate side pieces removably connected to each other at adjacent ends to form a frame, a channel defined in each side piece for reception of a window pane, first hook and-loop fastener means connected to said structure along a sash facing surface of said recess, second mating hook and loop fastener means connected to at least one of said side pieces along a surface thereof facing said sash facing surface for securing each of said side pieces within said recess in flush mounted relation with respect to said structure, quick disconnect means for removably connecting said adjacent ends of said side pieces together, said quick disconnect means being accessible and removable solely from the outside of said sash while said sash lies within said L-shaped recess; and a handle connected to each side piece upon cess.
3. The frame according to claim 1 wherein said quick disconnect means is a spring clip and adjacent ends of said side pieces define apertures to receive said clip.
4. The frame according to claim 1 wherein said side pieces connect to form a rectangle.
5. The frame according to claim 4 wherein said side piece receives a plastic member defining a channel for receiving an edge portion of said window pane.
