6 Claims.

This invention relates to window glass guides of the variety having a channelshape adapted to be applied to a vehicle body or the like around the outline of a window opening therein7 to support and cushien the edges of a glass window pane, one object of the invention being to provide such a guide having a more simple, practical and efficient type of construction.

Another object is to provide a window guide of the above character having a strong construction adapted to rmly support the window pane, but capable of being readily bent and curved to conform to a curved outline of the window opening, without otherwise substantially distorting its shape or deranging its several parts.

A further object is to provide a guide having the above advantages in a construction capable of being readily and economically manufactured, assembled and installed in place in the window opening.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features beingl pointed out in the claims at the end of the specification.

In the drawings:

Fig. 1 is a side view of a window guide embodying the present invention and showing the same partly curved to t the outline of a curved window opening.

Fig. 2 is an enlarged, perspective view of the same with parts broken away to more fully illustrate the construction;

Fig. 3 is an enlarged, transverse, sectional view of the same, and

Fig. 4 is an enlarged, perspective view similar to Fig. 2, but showing a modified construction.

The preferred embodiment of the invention, herein disclosed by way of illustration, comprises a supporting core or frame comprising transversely extending elements such as wire strands and bent into channel shape, the inside of the channel being lined with fabric thickened to provide cushioning surfaces. The exterior of the frame is also preferably covered with fabric and the transverse elements or wire strands ending in the outer edges of the arms of the channel are provided with means for continuously and smoothly supporting the covering fabric, while allowing relative movement of the parts, when curved to follow the window outline, without substantial puckering or derangement of the fabric or other parts.

Referring more particularly to thev drawings, the supporting core or framen indicated generally at IIJ, comprises, preferably, a continuous length of wire I l extending at spaced intervals transversely of the frame, as at I 2, to support the bottom of the channel. From such transverse portion l2, the wire is bent substantially at a right angle so as to extend upwardly as at I3 to support the side of the channel and is then bent as at I4 along the outer edge of the side wall or arm of the channel. This longitudinally extending portion It'. may be of more or less length, as desired, the wire being then reversely bent, as at i5, to extend down the side of the channel and across its bottom, as at I6, to the opposite side where the above described shape is repeated, thus providing a light, flexible frame having a desired stiffness controlled by the selection of wire stock of suitable size and composition to suit particular installations, as well understood in the art.

The frame so formed is preferably lined with a fabric strip Il, having portions i8 and i9 thickened or padded to cushion the side walls and bottom, respectively, of the channel, for contact with the glass surfaces. This cushioning is preferably accomplished by weaving the fabric to provide such cushioningportions with a relatively long resilient pile, such as disclosed in my Letters Patent No. 1,847,700, to firmly hold the glass against rattling and allow it to slide for opening the window with a minimum of friction. The fabric Strip I1, outwardly of such cushioning portions, has its edges turned outwardly over the edges of the channel arms and downwardly against their outer sides, to form portions 2i! for attaching the fabric to the frame, as hereafter described.

It is preferred also to cover the outside of the frame with a strip 2|, of cambric, cotton cloth or other suitable fabric, which covers the bottom of the channel and extends up the outer surfaces of its side walls into overlapping relation with the edges of the strip I1, as shown. The fabric strip l1, or at least the inner side thereof next the frame, and the fabric strip 2i are treated with a permanently tacky, water-resistant adhesive substance, such as an adhesive compound having a latex or other natural or synthetic rubber base, of known and commercially available varieties, the particular composition of which forms no part of the present invention. Such adhesive treatment of the fabric surfaces causes them to adhere to opposite sides of the frame and to each other between the wire strands and also secures the attaching portions 20 of the fabric ll to the edges of the outer fabric strip 2 i. By this means the inner and outer fabric coverings are securely attached to each other and enclose and protect the frame against inadvertent derangement of its strands.

The transverse strands of the frame, however, provide only an intermittent support, along the outer edges of its side arms, for the outer portions of the fabric strip Il, and means are provided along such edges to bridge the spaces between the strands and afford a continuous and smooth support for the fabric. Such means comprises for each edge of the channel a substantially U-shaped shield strip 22, of metal or other relatively stiff material, laid to embrace and enclose the ends of the transverse strands and bridge the gaps therebetween, the outer portions 20 of the fabric strip Il being secured over and smoothly supported by such shield strips, as shown. The arms of each strip 22 are long enough to engage the yportions I3 and I5 of the frame to hold the strip on the edge portions I 4 to which they are further secured by the covering fabric.

In the bending and curving of the guide to conform to the curved outlines of a window opening and its glass, the free edges of the side arms of the channel-shaped guide tend to be contracted, as at 23 (Fig. 1), while the bottom portion of the channel tends to be extended or stretched, as at 24. In such bending, the portions IG of the transverse strands of the frame lying in the bottom of the channel tend to be separated, while the portions lli of the strands lying in the outer edges of the channel arms tend to be moved somewhat nearer` to one another. The fabric materials forming the covering strips I1 and 2| have a sufficient amount of elasticity or stretch to allow such separating movements of the strands in the bottom of the channel and the fabric covering the free edges of the channel is capable of being suiilciently condensed to avoid puckering and allow it to remain in straight and smooth condition, but the shield strips 22, being of relatively rigid supporting material, are subjected to a longitudinally compressive force which tends to cause them to buckle laterally out of proper shape. In order to accommodate this force and avoid such lateral buckling, I have devised a construction which allows the shield strips 22 to slide and extend themselves longitudinally of the channel edges, such means comprising a correspondingly free arrangement of the strips in 'the assembly and the interposition of a non-adhesive substance between the strips and the overlying adhesive fabric strip Il. By such means the shield strips 22 are left free to slide in the fabric covering, while the ends of the frame strands I4 are free to slide within the shield strips.

Such non-adhesive substance for the shield strips 22 is preferably provided in the form of a covering strip 25, of a non-adhesive sheet material, such as cellophane or other known and commercially available thin flexible sheet material having a cellulose base, as commonly employed, for example, for packaging purposes. Strip 25 corresponds in shape to the shield strip 22 and covers its outer surface so as to prevent it from direct contact with the adhesive surface of the fabric, thus leaving the shield strip free to slide in the fabric and on the ends of the transverse wire strands of the frame.

The above described construction of the wire frame may be varied, of course, as illustrated by the embodiment shown in Fig. 4 of the drawings, wherev the strands 2t are not parts of a continuous wire but are formed with a separate length of wire for each strand, the side arms being secured together by interwoven strands 2l, of Wire or textile material, to space and rmly support the strands in place. The ends of these strands at each outer edge of the channel are supported and covered, as in the above described construction, by a shield strip 28, of metal or other suitable material, to provide continuous and smooth support for the fabric, but the nonadhesive susbtance interposed between the shield strip and the adhesive fabric may take the form of a layer 29 of wax or non-plastic material applied as a coating adhering to the outer surface of the shield.

It is evident from the above description that the invention provides a cushioning guide or channel having a core or frame of simple and inexpensive construction completely enclosed and protected by a fabric covering, with means on the frame for continuously and smoothly supporting the fabric along the outer edges of the channel and not only along the straight portions of the channel but along its bent or curved edges as well. Such construction affords a light, inexpensive and strong guide channel adapted to be easily bent to the curvature of the window outline and installed in the rabbet or groove usually provided for its reception, so as to insure a smoothly continuous cushioning guide or runway for the glass pane.

It will thus be seen that the invention accomplishes its objects and while it has been herein disclosed by reference to the details of preferred embodiments, it is to be understood that such disclosure is intended in an illustrative, rather vthan a limiting sense, as it is contemplated that various modifications in the construction and arrangement of the parts will readily occur to those skilled in the art, within the spirit of the invention and the scope of the appended claims.
