Smith, 1422 E. 22nd Ave., Denver, Colo. 80205 Filed Feb. 16, 1965, Ser. No. 432,986 Claims. (Cl. 160-420) This invention relates to a novel window shade adapted to be detachably mounted in a window opening and which includes ornamental designs or scenes of varying colors capable of being selectively moved into exposed positions to be viewed.

Another object of the invention is to provide ornamental window shade having illuminating means disposed bet-ween changeable transparent or translucent ornamental portions of the shade which are adapted to be viewed from opposite sides of the window.

A further object of the invention is to provide an ornamental window shade having novel means for detachably mounting it in a window opening.

Another object of the invention is to provide a window shade having manually actuated means for selectively varying the oranmental portions of the shade which are visible from opposite sides of the window.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a presently preferred embodiment thereof, and wherein:

FIGURE 1 is an elevational view, partly in section, showing the ornamental window shade in an applied position in a window opening;

FIGURE 2 is an enlarged edge elevational view thereof, looking from right to left of FIGURE 1, and taken substantially along the line 22 of FIGURE 4;

FIGURE 3 is an enlarged vertical sectional view taken substantially along a plane as indicated by the line 33 of FIGURE 1;

FIGURE 4 is an enlarged horizontal sectional view, taken substantially along a plane as indicated by the line 4-4 of FIGURE 1;

FIGURE 5 is an enlarged fragmentary horizontal sectional view, taken along the line 55 of FIGURE 1;

FIGURE 6 is a similar view taken substantially along the line 6-6 of FIGURE 1;

FIGURE 7 is a diagrammatic view illustrating the electric circuit of the window shade;

FIGURE 8 is an enlarged fragmentary view in elevation illustrating a part of the inner side of the window shade, and

FIGURE 9 is a horizontal sectional view, on an enlarged scale, taken substantially along the line 9-9 of FIGURE 8.

Referring more specifically to the drawings, the ornamental window shade in its entirety and comprising the invention is designated generally 10, and includes the rectangular frame, designated generally 11, composed of

sides

12 and 13, a top bar 14 and a bottom bar 15. A transparent or translucent panel 16 covers the inner side of the frame 11 and a panel 17, which is also transparent or translucent, covers the outer side of said frame. The

panels

16 and 17 are secured to the edges of the frame parts 12 15, preferably by fastenings 18.

Four

rollers

19, 20, 2'1 and 22 extend across the frame 11 and are journaled in the

sides

12 and 13. Said rollers have complementary ends which are provided with circumferential grooves 23, and said ends are journaled in four openings 24 of the side 12. Screws 25 are threaded downwardly into the side 12 from its upper edge through threaded bores 26. The screws 25 have restricted lower ends 27 which extend into the grooves 23 of the two

top rollers

19 and 21, to retain said rollers against movement crosswise of the frame 1 1 while permitting said rollers to rotate in the openings 24. Screws 28, corresponding to the screws 25, extend threadedly into the frame side 12 from its inner and outer edges, with the inner ends of said screws 28 engaging the grooves 23 of the

bottom rollers

20 and 22, for attaching said bottom rollers to the frame side 12 in the same manner that the

rollers

19 and 2 1 are connected to said frame side, as previously described. The rollers 19-22 have opposite ends 29 which extend through and are journaled in openings 30 of the side 13.

A curtain 31 has one end fastened to and wound on the top roller 19 and has its opposite end fastened to and wound on or adapted to be wound on the bottom roller 20. A curtain 32 has one end attached to the top roller 21 and its other end attached to the bottom roller 22 and wound or adapted to be wound on said rollers. The

curtains

31 and 32 are formed of transparent or translucent materials. Ends 29 'of the rollers 19 22 extend outwardly from the side 13 and are each provided with a series of circumferential-1y spaced outwardly projecting pins 33 which combine with peripheral portions of the rollers 29, from which said pins project, to form a sprocket wheel 34 at the righthand end of each roller, as viewed in FIGURE 1. An endless tape 35 is trained around the sprocket wheels 34 of

rollers

19 and 26 and has spaced openings 36 to engage the pins 33 thereof. An endless tape or belt 37, having spaced openings 38, is trained around the sprocket wheels 34 of the

rollers

21 and 22 and also around idler rollers 39, and the openings 38 thereof engage the pins 33 of said sprocket wheels 34. As best seen in FIGURE 1, the sprocket wheels 34 of the

rollers

21 and 22 are spaced a greater distance from the side 13 than the sprocket wheels 34 of the

rollers

19 and 20, so that the belt or tape 37 is spaced outwardly from the belt or tape 35 and with a part of the belt or tape 37 in side-byside relation to said tape 35 in passing around the idler rollers 39 which are disposed in longitudinally spaced relation to one another between the

rollers

19 and 20, as seen in FIGURE 2, so that said part of the belt or tape 37 can be readily grasped for actuating

rollers

21 and 22.

As best seen in FIGURE 6, each roller 39 is in the form of a sleeve 40 which is journaled on a stub shaft 4 1 which extends outwardly from the side 13. The stub shaft 41 has a head 42 at its outer end which engages in an internally enlarged outer end portion 43 of the sleeve 40. A restricted threaded stem 44 extends from the inner end of the stub shaft 41 through the side 13 and is engaged by nut 45 which secures the stem in said side.

A lamp socket 46 is supported by and depends from the top bar 14 between the

rollers

19 and 21, and a light bulb 47 is mounted in and depends from the socket 46 and is disposed between the parts of the

curtains

31 and 32 which extend between the rollers thereof.

Nuts 48 are secured in openings 49 of the side 12 and are disposed adjacent the upper and lower ends of said side and near its outer edge, to which the panel 17 is secured. Bolts 50 extend threadedly through the nuts 48. Each bolt 50 has a transverse opening 51 near its outer end to receive any long slender instrument, not shown, by which the bolt can be turned in its nut 48, for a purpose which will hereinafter be described.

FIGURE 7 diagrammatically illustrates the electric circuit of the bulb or light source 47, including the wiring 52 which is adapted to be connected to any conventional domestic electrical outlet, not shown, and in which is interposed a conventional electrical switch 53 which is preferably mounted in the frame side 12.

As best seen-in FIGURE 8, the inner panel 16 has a 'ectangular opening 54 which is normally covered by a lap 55 formed of the same material as said panel and which is stitched, as seen at 56, to the outer side of the panel 16, above the opening 54 thereof. The inner curtain 51 is provided in a part thereof with a longitudinally ex- :ending slit 57 which may be closed by lacing 58, if lesired. The belt 35 may be manually engaged and moved to revolve the rollers 19 and simultaneously in :he same direction for moving the curtain 31 therebetween for positioning the slit 57 behind the opening 54. The lap 55 may then be rolled upwardly or otherwise raised after Which the lacing 58, if utilized, may be removed to afford access to the light bulb 47 through the opening 54 and slit 57, for removing and replacing the light bulb, if necessary.

As seen in FIGURE 1, the curtain 31 preferably contains various designs or ornamentations, as indicated at 59, and different portions of the curtain may be of various colors. The curtain 32 also contains designs or ornamentations and includes portions of difierent colors. For example, the

curtains

31 and 32 may include scenes representative of different seasons of the year or which are appropriate to various holidays.

The shade 10, as shown in FIGURES 1 to 4, is disposed in a window opening 60 formed in a Wall 61. The outer part of the frame 11 is disposed in the inner part of the opening 60 and inwardly with respect to the window pane or sash, not shown, of the window. The outer portion of the frame side 13 abuts one vertical side 62 of the opening 60 and the bolts 50 are adjusted, as heretofore described, in the nuts 48, to be advanced outwardly to abut the opposite vertical side 63 of said opening 60, for detachably clamping the outer portion of the frame in the inner part of the opening 60. Thus, the sprocket wheels 34 will all be spaced from the inner side of the wall 61, as seen in FIGURES 2 and 4, to permit manual movement of the

belts

35 and 37 for revolving the rollers 1942 to effect adjustment of the

curtains

31 and 32, so that different scenes, colors or ornamentations will be visible through said curtains and through the

panels

16 and 17 when the bulb 47 is energized. It will be readily apparent that what is exposed on the curtain 31, between the

rollers

19 and 20, will be visible through the panel 16 from the interior of the enclosure of which the wall 61 forms a part, while what is exposed on the curtain 32, between the

rollers

21 and 22,-will be visible through the panel 17 from the exterior of the enclosure of which said wall forms a part.

Various modifications and changes are contemplated and may be resorted to, without departing from the func- 4. tion or scope of the invention as hereinafter defined by the appended claims.
