Application March 19, 1942, Serial No. 435,372

Claims. (Cl. i60-178) This invention relates to improvements in Venetian blinds. l

One object of my invention is to provide a Venetian blind element which when in vertical position, or when the Venetian blind is closed.'

will permit the rays of sunlight to be refracted therethru into a room.

Another object of my invention is to provide a Venetian blind element which will prevent the heat of the sun's rays from penetrating into a room and cause the said heat rays to'be reiiected away from the respective Venetian blind element.

Another object of my invention is to provide a Venetian blind element of a curved nature which has a light receiving surface and a light distributing surface.

Other objects resident in my invention may become apparent by reference to the accompanying drawing, and the ensuing description, wherein like numerals represent like parts, and in which:

Fig. 1 represents an enlarged longitudinal -cross-'sectional view of a conventional Venetian blind structure particularly pointing out the element comprising my invention.

Fig. 2 is a fragmentary isometric view of my invention.

Fig. 3 is a fragmentary and enlarged longitudinal cross-sectional view showing the important features and structural novelty responsible for eiiectively permitting the rays of sunshine to be admitted into a room and eliminating the glare ad heat thereof.

Referring, more particularly, to Figure 1, the elements 4 and 5 are the conventional textile ribbon element supports for suporting theVenetian blind element. The element I is the lateral support, and the elements l, 5, and 'I are adapted to confine the Venetian blind elements in their proper position. No claim is made with respect to this structure. The conventional guide rope 6 is also utilized, and suitable openings are provided in the` Venetian blind element in accordance with standard practice. The Venetian any substance which will provide opacity to the portion ofthe Venetian blind so covered. The concave portion I8 and the convex portion II are left uncovered and highly polished. The Venetian blind elements are, preferably, made of lucite or a similar product which has a high index of refraction and will permit light to be refracted therethru without undue distortion.

The Venetian blind when closed will cause the element i5 to be in the position shown by the full lines in Figure 1, and may be opened to any position within the range of rotation of the said elements as shown in dotted position or to any degree or range that the pull cord will permit setting the elements in open position.

When in closed position, the rays of sunlight will strike the upper concave surface I8 thus tending to concentrate the rays of light i8 and causing them to pass thru the curved body 8 and ultimately to be refracted and diused as at il by virtue of the convex portion i9. The opaque portions I3 and I4 will prevent the light from escaping thru the body 8, and cause the same to be disseminated thru the convex portion i9, the surfaces i3 and I4 may be either completely opaque or translucent which ever may be deemed more desirable.

The rays ii when emanating from the convex surfaces i9 will ultimately merge and furnish an even curtain of light of uniform intensity. The heat from the suns rays will strike the surface I8 and will be reflected therefrom, inasmuch as these surfaces are highly polished, and inasmuch as the heat is not refracted thru bodies, but because of the thinness of the section 8 very little conductivity of heat will be brought into the room, and hence by convection the amount of heat will be but negligible.

Altho, I have indicated suggestively that lucite is used as a material, preferably for the construction of the blind elements, any other suitable refractive material may be utilized. The elements may be acclimated to any standard or any Venetian blind t'ype of structure, the main objects not being interfered with, and the result being attainable by virtue of the particular structure embodied in the Venetian blind element IS comprising my invention.

Inasmuch as the invention is depicted in a preferred form, it is understood, and I, hereby, reserve any and all modifications coming within the scope and spirit of my invention as well as within the purview of the foregoing description; my invention tc be limited only by the subioined claims.

Having thus revealed my invention what I claim as new and desire to'secure by Letters Patent is.:

1. A Venetian blind element comprising, a body portion, one of the parallel edges thruout its length being provided with concave means. the remaining edge being provided with convex means.

2. A Venetian blind element comprising, a curved body portion, one of the parallel edges thruout its length being provided with concave means, the remaining edge being provided with convex means.

3. In combination, suitable Venetian blind element cradling means, and a series of blind elements each comprising, a body portion, one of the parallel edges thruout its length being provided with concave means, the remaining edge being provided with convex means.

yfi. In combination, suitable Venetian blind element cradling means, and a sexies of blind elementa each comprising, a curved body portion, one o! the parallel edges thruout its length beingY provided with concave means, the remaining edge being provided with convex means.

5. A Venetian blind element comprising, a body portion, one of the parallel edges thruout its length being provided with concave means, the remaining edge being provided with convex means, and opaque means associated with the inner and outer surfaces of the said body portion.
