CLIP-TYPE SHIELD Filed A ril 27, 1965 I N VEN TOR. RUPERT L. EVANS ATI'ORNEY.

United States Patent 3,345,779 CLIP-TYPE SHIELD Rupert L. Evans, Hollywood, Fla., assignor to Crossly Window Corp., Dade, Fla. Filed Apr. 27, 1965, Ser. No. 451,156 6 Claims. (Cl. 49-501) ABSTRACT OF THE DISCLOSURE An integral, clip-type shield for use over the end of a stile which has a U-shaped slot for reciprooably receiving a monorail of a header, in which the shield includes a plate-like body having tine-carrying, displaceable tabs for grippingly engaging the stile on opposite sides of the U-sh-aped slot thereof and enclosing said slot for cushioning the monorail during relative movement between the stile and header.

This invention relates to a clip-type shield, and, more particularly, to a clip-type shield receivable as a liner for a U-shaped slot in the end of a sliding panel stile to guide the panel for sliding movement relative to a track depending from a header.

As is perhaps well known, sliding panels are quite often provided with a U-shaped slot in the ends of the stiles of the panel to receive a guide track of a header which moves relative to the slot walls on sliding movement of the panel. In the past, it has been found desirable to provide a nylon liner for the slot which is secured to the stile by means of screws passed thorugh flanges on either side of the liner. This invention provides a clip-type guide shield for the end slots of such stiles which includes integral fastening means whereby auxiliary fasteners are not required to secure it to the stile.

It is, therefore, an object of this invention to provide a clip-type shield or guide of tough, resilient, synthetic elastic material to line the U-shaped slot of the stile of a panel to receive a guide track or'rnonorail therein and for sliding movement relative thereto, said shield including integral gripping means to secure it in position.

Itis another object of this invention to provide a shield of the type described hereinafter which is relatively simple in construction, is inexpensive to manufacture, and is otherwise well adapted for the purposes for which it is intended.

In accordance with these and other objects which will become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings in which:

FIG. 1 is an exploded partial perspective view of the header of a frame and the stile of a sliding panel and illustrating the instant shield in perspective relation to the header andstile;

FIG. 2 is a second perspective view of the guide; and

FIG. 3 is a side elevation view of the shield installed on the stile in FIG. 1.

Referring more particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout the different views, and referring particularly to FIG. 1, the numeral 11 generally designates the clip-type shield which is tough, durable, elastic, synthetic material, such as nylon, which, by reason of its structure, as is set forth more fully hereinafter, is resilient and adapted to cling in place on a sliding panel in the position shown in FIG. 3.

Referring to FIG. 1, the numeral 12 generally designates a channel-form header of a closed frame, such as that commonly installed in building openings, to accommodate sliding movement of a panel protectively nestled between the flanges 18 and 20 and guided in sliding movement by a monorail 22 depending from the web 16. The numeral 14 generally designates the stile of the panel which is ordinarily of an extruded length of metallic material having a stile side 25 with a U-shaped slot 24, having a floor 26 and

vertical side walls

28 and 30, to receive the monorail or guide track 22 therein. On either side of the floor of the

slot screw holes

32 and 34 are provided to accommodate passage of headed screws for engagement with elements carried in the panel but which form no part of the instant invention and are, therefore, not shown. Above the holes two

recesses

36 and 38 are ordinarily provided to receive screws to hold a shield in place, and the edges of which recesses, it will be seen, are utilized to co-operate with

tines

70 and 72 of the instant clip-type shield 11 to securely connect it in the slot 24 of the stile.

Referring in detail to the clip-type shield 11, seen in FIGS. 1 and 2 in perspective, it comprises a relatively thin plate body 40 or flange to overlay the interior surface of the stile side 25 and a first and a

second tinecarrying tab

50 and 52 held in spaced apart and confronting relation with respect to the plate as flanges of the U-shaped slot liner. The side walls of the liner 54 and 56 are sutficiently thick to cushion the stile relative to the web 22 and are sized so as to completely and snugly overlay the floor and side walls of the slot 24. The upper surface of the shield is flat to ride smoothly under a header web when installed and the walls of the mouth of the slot are thickened to normally constrict the mouth to define wiper edges 58 and 60 of web-gripping cushion surfaces 66 and 68. The lips of the

mouth

62 and 64 are beveled inwardly to the cushion surfaces of maximum constriction 66 and 68; it is noted that the said confronting cushion surfaces of the constricted month are generally vertical between the lips and at the entrance to the main width of the slot. As can be seen in FIG. 2, the

tines

70 and 72 respectively confront recesses 46 and 48 in the plate portion of the body, the said tabs being congruent with respect to the recesses but with the tines opposing a portion only of the recesses which is outwardly of the slot walls. As can be seen in FIGS. 1 and 2, each of the tines is arrow-shaped to define a barb edge for a purpose which will become apparent in the next paragraph.

In assembly, the guide shield is positioned in the symmetrical relation shown in FIG. 1 above the stile slot 24 with the U-shaped liner of the shield being pressed depthwise into the slot with the plate overriding the inner stile surface until the arrowed edges or slanted surfaces of the tines ride onto the outer surface of the stile side.

Continued downward pressure on the shield expands the distal edges of the tabs away from the plate body a slight distance about the hinge lines, i.e., the lines of connection with the U-shaped liner, which also draws the mouth to a slightly constricted portion, by reason of the fact that the distance between the opposing faces of the tabs and the plate is the same as that of the thickness of the stile and the constriction of the mouth takes advantage of the increase of the distance between the tabs and the plate resulting from the movement of the distal edge of the tabs with respect to the aforesaid hinge lines. As continued pressure is applied to press the shield downwardly into the slot, the tines snap into the

recesses

36 and 38 of the stile as the barb edges clear to relax the tabs with respect to the hinge line, and, substantially simultaneously, the mouth relaxes to the open position as the pressure causing the outer edges of the tabs to expand and the edges of the tines is relieved and, therefore, the tine edges move into tight abutting engagement with the side walls of the recesses of the stile. Thus, the shield is securely fastened in the stile without requiring additional fastening means with the liner or spacer portions protectively lining the slot and the cushion surfaces being adapted to snugly wipe and grip the web when the panel is assembled thereto, the said beveled edges guiding the distal end of the mono-rail into the slot 49. Further, by reason of the fact that in the preferred construction the tabs as seen in elevation are at least congruent to the recesses 46 and 48 of the plate portion of the body and the tines are in abutting engagement with the outer edge of the stile recesses, the tabs protectively overlay the recesses of the stile face to protect it from the elements. In the preferred embodiment, the inherent resiliency of the plastic material, which is prefera'bly nylon, and which holds the tines into tight engagement in the stile recesses and, also, the Ushaped liner in expanded relation into abutting engagement with the sides of the slot, may be supplemented by slightly bending the distal edges of the tabs toward the plate body and by forming the liner walls with an angle of divergence slightly larger than the included angle of the slot, when the shield is molded. Further, the apron or skirt of the plate in which the

holes

42 and 44 are provided is of such a length that the

screw holes

32 and 34 of the stile are in alignment when the clip-type shield is in place. Thus, it is seen that by reason of the structure aforesaid, the shield is adapted to be quickly and securely snapped in position on a stile and without the use of tools whereby it can then be moved as a unit to a site for panel assembly without the requirement of additional fastening means to accompany the stile and shield.

While the instant invention has been shown and described herein in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is therefore not to be limited to the details disclosed herein, but is to be accorded the full scope of the claims so as to embrace any and all equivalent apparatus and articles.
