SLIDER FOR INSTALLATION OF' CURTAINS Filed Sept. 19, 1957 2 aa 2O F"\ 3e 977% MAM ATTORNEYS.

United States atent O SLIDER FOR INSTALLATION OF CURTAINS William C. Wootton, Fremont, Calif. Application September 19, 1957, Serial No. 684,939

' z claims. (Ci. 1li-9s) This invention relates to installations on the wallsv of buildings and vehicles of decorative or utilitarian iexible panels such as curtains, the walls usually having windows, which installations are of the type wherein opposite edges of the panels are engaged with guideways which hold the panels extended but permit them to be moved in whole or in part in a plane parallel to the wall. The object is to provide an improved mounting element or slider for jo'ining the panel edges and the guideways by use of which the desired elective installation in spite or" structural incongruities between the panel and the guideways is realized in a superior manner, as will appear as the description proceeds.

The invention will be well understood by reference to the following'description of an illustrative embodiment thereof shown in the accompanying drawings wherein:

Fig. 1 is an elevation of the interior of the wall of the body of a passenger carrying airplane exemplifying the invention. The tgure is schematic and not realistic as to proportions;

Fig. 2 is a vertical section through a panel and its supports;

Fig. 3 is an elevation of one of the slider elements;

Fig. 4 isa top plan view thereof;

Fig. 5 is a section on the line 5-5 of Fig. 3;

Fig. 6 is a side view of the slider as seen from the right of Fig. 3, with part broken away; and

Fig. 7 is a section on the line 7-7 of Fig. 6, but showing the shank extended to the position shown in dotted lines in Fig. 3.

Referring now to Fig. 1 of the drawings, I have there shown schematically, as viewed from the interior, the wall of an airplane which wall is pierced by a series of windows 10. Above and below the series of windows are top and bottom guideways 12a and 12b respectively, between which are extended curtain panels 14. Herein a pair of curtains isprovided for each window similar to so-called sash curtains, but secured at their top and bottom margins to the guideways. 'Ihey may-either be extended over the windows or drawn to one side to any desired degree, and are illustrated in the drawing as being shirred centrally and secured by tiebacks 16.

Referring now to Fig. 2, each of the guideways may be formed by a suitable metallic molding having spaced anges 18 with inturned margins 20 and 22 in the same plane. The edge of the inturned part 20 constitutes a rail or track on which the sliders to be secured run while the opposing part 22 is in elect a guard rail to hold them in position.

The sliders as seen in Figs. 3 through 7 include a cylindrical neck portion 24, for riding on rail 20, an inner head 26 and an outer body portion 28. The head 26 which may be substantially conical as shown is received in the space between the flanges 18 and is of a diameter greater than the space between the inturned edges 20 and 22, so that the slider is supported on track 20. The head maybe entered into the space between the flanges and behind the parts 20 and 22, either from the end of the ICC y guideway or through a gateway formed at a suitable point in portions 20 and 22 in well known manner. The slider cannot be released by direct outward pull and the cooperation of the head 26 with the guard rail 22, and of the body 28 with the outer face of rail 20, prevents it from tipping to' any considerable angle in a plane transverse to the wall.

In accordance with the invention a resiliently extensible connection is provided between a group. of sliders and the adjacent panel edge along opposite sides of the panel for reasons hereinafter referred to. The drawings illustrate a preferred form of device for effecting such connection. The body extends laterally, viewing Fig. 4, of the neck portion 24 and is provided with a central chamber 30 (see Fig. 7) in which is resiliently suspended a shank 32 the projecting end of which is anchored to the curtain edge. Herein the body is of generally oblong cross section and pierced with an oblo'ng slot 34 opening through the ends thereof as seen in Figs. 4 and 5. Along the longerY walls of the slot are recesses 36 which do not extend through that end of the body which is the lower end viewing Figs. 3 and 5, so that shoulders 38 are provided at the front and rear of the slot 34. The shank 32 is a generally similar oblong member fitting freely within the slot 34. An opening through the upper end of the shank (see Fig. 7) defines upper and lower cross parts 40 and 42 respectively between which is received the helical compression spring 44, one end of which will be supported by lthe shoulders 38 at one end of the chamber, the other end of which bears against the cross bar 40. From the cross bars 40 and 42 integral to'ngues 46 and 47 may extend which enter the ends of the spring and serve to position it. The ends of these may closely oppose one another, as seen in Fig. 7.

- Normally the spring retracts the shank portion 32 within the body to the position shown in full lines in Fig. 3, with its distal end projecting. This distal end is secured to the edge of the curtain but under strain it may be drawn outward from the body to the dotted line position of Fig. 3 and in full lines in Fig. 7.

The distal end of the shank is herein shown as provided with a snap-fastener socket 48 secured by aV washer 49 adapted to cooperate with a stud member 50 secured to the edge of the curtain. The so'cket 48 is larger in cross section than the slot 34 and prevents withdrawal of the shank 32 from the body from the upper end in Fig. 3.

It is convenient to assemble the spring 44 with the shank 32 in the manner shown, insert the shank into the body from above and then apply the socket 48 to the distal end of the shank. The tongue47 may easily be bent to one side to permit the spring to be engaged thereover.

The slider comprising the parts 24, 26 and 28 and likewise the shank 32 may be, and preferably are, molded from nylon or similar form-retaining but resiliently ilexible material. j p

'I'he resilient connection of the curtain to the sliders facilitates mounting of the curtains and moving them to their desired positions along the guideways. As portions of the curtains are shifted, perhaps by a force applied to a vertical edge, the strains are equalized and the movement facilitated. Violent jerks or pulls occurring during the use of the curtains are cushioned and no breaking or tearing will result. If the guideways are not strictly parallel to the line of fastener studs, either because of so'me constructional feature of the installation, as for instance to adapt it to a wall havingra slightly curved boundary, or because of inaccuracies in the installation of the guideways or of the studs 50, the extensibility of the connecting means compensates. Shrinking or stretching of the 3 fabric in use or as a result of washing or cleaning is also compensated for.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire thel present embodimentto be considered in all respects as illustrative and not restrictive, as is in fact clear in several matters fro'm the description itself. Reference is to be had to the appended claims to indicate those principles of the invention exemplied by the particular embodiment described and which I desire to secure by Letters Patent:

1. A slider for connecting the edge of a curtain to a guideway comprising an outer or female element and an inner or male element, each a unitary molded unit, the relatively remote ends of said elements having means for connecting one to the guideway and the other to the curtain, the outer element having a vertical slot therethrough of generally oblong cross-section and having recesses in its wider side Walls. above its lower end to provide seats for the lower end of a helical spring, the sides of which are received in the recesses, the inner element comprising a shank of oblo'ng cross-section to lit the slot, the shank being cut away to define upper and lower crossbars,

the inner element being movable upwardly to project the shank beyond the upper end of the outer element to expose laterally a considerable portion of the distance between said crossbars for the lateral introduction of the helical spring between them, the cross bars having projecting tongues to enter the ends of the spring.

2. A slider as set forth in claim 1 wherein the tongue on the lower crossbar is resiliently llexible laterally from the plane of the shank and its upper end normally lies closely adjacent to and in alignment with the tongue on the upper crossbar. Y
