Cayton, Los Angeles, Calif assignor to Louverdrape, Inc., a corporation of Qalii'ornia Filed Mar. 12, 1962, Ser. No. 178528 tllaims. (El. 74-91) This invention relates to an improved vertical blind and specifically to a non-traversing blind.
It is an object of this invention to provide a blind of rugged and durable construction which may be readily mounted in or removed from an opening such as a window or the like.
Still a further object of this invention is to provide a blind which is readily and easily assembled with a resultant savings in labor and cost.
Still a further object of this invention is to provide a novel means for supporting the louvers.
Still a further object ofthis invention is to provide a blind having novel means for rotating the louvers.
Other objects and advantages will be readily apparent from the following description.
In the drawings:

FIGURE 9 is a fragmentary perspective of the rack driving means.
FIGURE 10 is a fragmentary perspective of the underside of FIGURE 9.
FIGURE 11 is a perspective of the locking element.
FIGURE 12 is a perspective of the pinion.
FIGURE 13 is a perspective of the clip.
At the upper and lower edges of an opening, a channel 26 is positioned. Between these channels a series of louvers 22 are rotatably mounted, such louvers being preferably of cloth although any suitable material may be used. Since the two channels are identical, only the upper'will be described in detail.
Said channel is essentially U-shaped in cross section with the open ends bent inwardly facing one another as at 24, and a pair of opposed inwardly facing ribs 26 are spaced above the closed face of the channel 28. This closed face 23 has a series of holes 30 along the length thereof. A gear element 32 has a cylindrical protuberance 34 formed thereon which projects through a hole 3%. Immediately above protuberance 34 on gear element 32, is formed pinion gear teeth 36 for a purpose hereinafter to be described.
A clip 33 projects through gear element 32 and is held by a spring 40 with the extremity of said clip below face 28 supporting one end of a louver 22.
The upper edge of gear element 32 has opposed fiat sides 42 which when properly positioned permit element 32 to pass between ribs 26. The gear is then rotated slightly until same is confined by ribs 26 in the lower part of the channel. A rack 44 has an L-shape with one leg 46 extending between a rib 26 and face 28 of the channel and the other leg 48 having gear teeth 51? meshis a view taken along line 3-3 of FIG- ing with the gear teeth 36 on the gear elements 32 so that longitudinal movement of the rack rotates the gear elements and hence the louvers.
To move the rack a driving block 52 is provided having opposed grooves 54 therein receiving ribs 26. Several gear teeth-56 are provided to engage teeth 50 on rack 44. Block 52 has an internally threaded bore58 by which same is mounted upon a threaded shaft 6%. Near the outer extremity of shaft 6% a flange 62 is formed which abuts against end cap 64 secured in channel 20 by pins 66 which project through the channel walls and a lock tab 63 formed on the cap. Mounted on shaft 60 within cap 6-.- are a pair of pulley halves 70 and 72 secured by pin 74 to the shaft and receiving a beaded chain 76 therebetween. The beaded chain engages lugs 78 in the pulley halves so that pulling on the chain rotates the shaft 69 to drive rack 46 and hence rotate the louvers.
The upper channel 20 may be secured by any suitable means such as flanged sleeves Si and screws 32 into the upper edge of the window. It is desirable to have the lower channel readily removable to facilitate cleaning. To facilitate this a locking member 84 i utilized rotatably secured by a suitable screw projecting through hole 86 and into the lower sill. The member 84 has a cylindrical body 88 carrying a pair of opposed locking tabs 9% and a tabbed handle $2. The channel 20 is lowered over one or more locking members which are then rotated so that tabs 9t; overlie inwardly bent ends 24 securing the channel in place.
In operation the gear elements 32 are meshed with rack 44 with protuberances 3:4 in holes 30 and clip 38 projecting therethrough supporting louvers 22 which are aligned with one another and which are then rotated from overlapping positions as viewed in FIGURE 1, to a fully open position wherein same are substantially parallel by pulling on chain 76 which as seen in FIGURE 1 simultaneously drives the upper and lower ends of the louvers.
W'hile what hereinbefore has been described as the preferred embodiment of this invention, it is readily apparent that alterations and modifications may be resorted to without departing from the scope of this invention and such alterations and modifications are intended to be included within the scope of the appended claims.
I claim:
