Application August 27,

7 Claims.

My invention relates to shades for windows and the like and has for its object the provision of a shade composed of a preselected number of sections independently and removably secured in place so as to permit the respective shade sections to tilt about horizontally disposed axes; the mounting of the respective sections involving means whereby said tilting action is not only made possible but the respective shade sections made to tilt in unison about the horizontally disand a maximum spaced relation between the shade sections maintained, while also permitting vertical movement of all the sections toward the top or toward the lower part of the window frame.

The invention involves spective shade sections,

made of rigid material, may be independently removed and replaced without in any way dismounting or interfering with the shade mounting mechanism or elements.

The invention, its purposes and advantages will all be readily comprehended from the detailed description of the accompanying drawings, wherein:

the window frame of one of the perspective view of the clip a window opening 1937, Serial No. 161,290 (Cl. 156'l7) My invention contemplates the provision of suitable housings or channels adapted to be secured to the sides of the window-frame on the room side of the window-sash and to extend throughout the heighth of the window. In order 5 to enable easy application to window-frames the housings in the particular exemplification of the invention are shown consisting of metallic strips 2|, 2| of angle formation in cross section, see Flgure'5, with attaching flanges or lobes whereby 10 the respective strips may be secured to the windew-frame as indicated at 22 in Figure 5. These strips are secured to the window frame to provide a vertical slotway 23, at each side of the window, extending substantially throughout the 15 heighth of the window-frame for the purpose of receiving one of the reduced ends of the trunnion members 24 shown in detail inFigure 11. The body portions of the trunnion members 24 the trunnions and the cross-bars to rotate together; the inner end of the trunnion member "being secured in the opening 26 of the crossebar 25. This operative relation between cross-bars 30 and trunnions may be accomplished either by threading the reduced ends of the trunnions and providing the cross-bars with tapped openings, or thereduce'd ends of the trunnions may be forced into openings in the cross-bars.

The outer reduced end of each trunnion member 24, namely the end which extends through the slotway 23, is intended to operatively fit into an aperture 21 formed in the side of a clip-holding element 28, shown in detail in Figure 8; the 0 relation between the trunnions and the clip holding elements 28 also being such that the trunnions and clip-holding elements will oscillate or rotate together.

It will be understood that a similar clip element 28 is secured to each trunnion and therefore a clip element 28 will be arranged in each channel at opposite sides of the window-opening.

The clip holding elements 28 are slotted at 29 These clip elements preferably each consist of I sheet metal folded upon itself lengthwise to proenable the trunnions pletely slide onto or telescope with the holding element 28, the rear or closed longitudinal side of the clip 38, at one end, is slotted at 34 a distance commensurate with the non-slit portionor solid end 35 of the clip-holding element 28. The forward or open ends of the jaws of clip 38 are also preferably formed to provide a socket or longitudinal channel 38 intended to receive the rolled or beaded portion'3l of the shade strip 38, see Figure 7.

The shade strip 38 may be made of'opaque shade cloth or any suitable fabric, and in order to obtain a suitable bead to ensure proper'gripping on the part of the clips 38, the immediate ends of the strips of shade material may be provided with thin metallic U-shape binding strip 38, see Figure '7. After the ends of the strips of shade cloth have been provided with the binding strip 39, the ends with the binding strips are rolled upon themselves, as shown in Figure '7, to provide'the beaded portion 38; the insertion being made from one end of the clip to allow the shade strip 38 to extend through the open jaws of the clip member 38, as shown in Figure 5.

After each end of the shade strip 38 has been beaded as heretofore described and the head inserted into a clip 30, the clips are then inserted onto the prongs 33 of the holding members at opposite sides of the window openingrthe insertion of the clips being made with the slot 34 of each clip disposed toward the clip-holding element 28. The shade-strips, which initially are of length approximating the distance between the clip-holding elements 28 at opposite sides of the window opening, will be firmly and at the same time removably held in place; or sections being so held that they may be separately removed and replaced.

In order to maintain the shade-strips taut and also to frictionally hold each clip-holding element in its adjusted positions, the trunnions 24 located within the housings or channels, formed by angle strips 2|, 2| at opposite sides of the window, are provided with suitable tension producing elements which may be in the nature of the coil springs 40 arranged around the trunnions 24, as shown in Figure 5; or any other suitable method may be employed for placing the clip holding members under tension and provide holding relation with the inside of the strips 2| of the housings. To

reduced ends of the trunnion members 24 are shown provided with washers 4|, the one bearing against the cross-bar 25 and the other bearing against the innersides of the supporting frame members 2|, 2| which constitute the housing or channel. It is apparent that the springs at opposite ends of each shade-strip or section tend to pull the holding members 28 toward opposite sides of the window-frame and hence will maintain the shade-strips taut and will also frictionally hold the members 28 with the shade-strips or sections in their adjusted positions. I

The cross-bars 25, at their ends, are shown provided with

suitable openings

42, 42 intended to receive

pins

43, 43 to which suitable chains 44 are attached; the chain-links being such that free rotative movement between the pins and the strips or sections to be t 31 which is then inserted endwisely into the groove 38 of each clip the shade-strips to be easily rotated,-the

chains is possible. The chains 44 may be con tinuous from top-to bottom with correspondingly spaced links thereof secured to the pins 43 of the respective cross-bars or arms so that the respective cross-arms and associated elements, together with the shade-strips, may be equally spaced apart vertically commensurate with the width of the shade strips 38 so as to permit the shadetilted into substantially slight lapping relation with desired to make a complete vertical position and each other when it is closure of the shade.

One of the shade-sections, preferably the bottom section 45, is made of rigid material such as wood. This section or heavy slat 45 is also removably held at its ends by clip members 48, one at each end. These members 48 each have a projection or joural 41 (which may be similar to journal or trunnion members 24) which extends through the'slotqway 23 into the housing, with the inner end'provided with an enlargement or washer 4 like in the previously described trunnions and a washer 4| adjacent the housing forming strips 2|, 2|, posed about the trunnion or journal 41 and between the washers 4| 4|, so as to induce frictional the bottom section or with a coil spring 48 dis-.

their respective members 28 with attached shadestrips 38 to be likewise rotated or tilted.

The operation of the sectional shade is entirely accomplished through manipulation of the bottom rail or master strip 45; the tilted position of the respective sections bein maintained by the pressure of the springs as heretofore described.

When it is desired to raise the shade, the operator grasps the bottom rail and turns it into horizontal position which likewise positions the v upper shade-sections and the cross arms. The bottom rail is then forced upwardly causing its trunnions to slide upwardly in the slotways 23 of the housings, causing the succeeding shadestrips or sections to pile up on the bottom rail or master strip 45. The various shade-strips or sections are all returned to their normal positions and spacing by pulling the master strip or bottom rail downwardly until the slack in the chains or flexible element is taken up.
