SUN SCREEN.

Application filed April 28, 1925.

Z 0 all whom. it may concern: 9

Be it known that TOMOSUKE OI-IARA, a subject of the Empire of Japan, residing at No. 25 Komagomehayashi-Gho, I-Iongo-Ku, Tokyo, Japan, has invented certain new and useful Improvements in Sun Screens, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention has relation to sun screens and especially to screens which while affording adequate protection against the sun, are so fashioned and constructed as to permit of easy and convenient extension and contraction in folding and which when extended will permit a free circulation into and through the room for which the screen is used.

According to my invention the screen comprises a series of horizontal bars or slats to the outside of which are attached by suitable connecting devices, metallic strips bent to form angular projections arranged at equal distances apart in zig-Zag relation.

These horizontal bars or strips are connected together by two series of cloth strips; one being attached to the faces of the angular bends, and the other to the connecting devices, to provide devious air spaces for ventilating purposes.

The strips of cloth form supporting connections between the horizontal members of the screen, and provide for the convenient extension and folding up of the same.

My invention consists of the novel construction and combination of parts hereinafter more particularly described and claimed.

In the accompanying drawings, Fig. 1 is a rear view in elevation of a sun-screen constructed as an example of my invention.

Fig. 2 is a sectional view on the line-.1-2 of Fig. 1.

Fig. 3 is an enlarged view in section of a connector of the angular bends and h0rizontal bars constituting the frame work of the screen.

Fig. 4: is a sectional view of a modification of the screen.

Fig. 5 is a top View of the screen.

Fig. 6 is a front elevation of the same.

Figs. 7 8, 9 and 10 are detail views.

As illustrated in the drawings, the screen embodying my improvements comprises a series of horizontal bars or slats, B, to the outer surfaces of which are attached the Serial No. 26,477.

bends C, which consists of short strips of metal bent to angular shape and arranged in zig-zag series, the outer angles projecting forward.

The bends C and the bars B are connected together by the connectors M, which are of rectangular oblong shape, forming boxes or troughs, and are preferably made of metal.

The cavities or spaces between the sides of the box-like connectors M are designed and adapted to receive and embrace the transverse bars B, and the ends of the bends C. The bars B rest against the inner walls of the connectors M, while the adjacent ends of two of the bends C he one outside the other, against the bars B, and between the latter and the slotted cross piece M of the connector M.

One end of each of the bends C is bent outwardly, to form a lug m, which is inserted in the slot of the cross piece M and interlocked therewith.

The connectors M are fastened to the bars B, and the ends of the bends lying between the bars and the cross pieces M of the connectors are held firmly in place by frictional contact.

The advantage of separate angular bends C, and connectors M is that the screen may be readily adjusted or fitted to window openings of Various widths without the necessity of cutting of the bends. This adjustment is effected by contracting the bends or angular strips C so as to make their angles more or less acute and by locating the connectors M in the proper positions to receive the ends of the bends C. When the bars are of proper length to lit the window opening to which the screen is to be applied, the bends C may be contracted or expanded according to the length of the bars B.

Strips of cloth D, are attached to the outer portions of the bends 0 connecting the latter in vertical series. The edges of the strips D terminate a short distance from the inner angles of the bends, leaving narraw spaces between the edges of the adjacent strips, for the circulation of air. Other strips of cloth A are attached to the inner sides of the connectors M and form a series of strips alternating in position with the strips D and facing the spaces between the strips D. The relative position of the strips A and D provides for the circuitous or indirect passage of the air through the screen.

The framework E is preferably made of wood and is of rectangular shape. The vertical, opposite faced parts are grooved at F on their inner sides to provide for the slid ing of the outer ends of the zig-zag member placed parallel. Near both ends of the lowest flat bar B there is provided two rings K. K. to which one cord I is connected and this cord is passed over pulleys J. J each of which is fixed at the top part of the frame work corresponding to the position of the rings at both sides. The free ends of the cords are tied together with such a length of cords as to permit of the pulling up or down of the fiat bars B through equal distances of both ends of the bars. The shade when in a lowered and expanded position may be raised by pulling the free ends of the cords I. This will directly elevate the lowermost bar B of the screen and bring it in contact with the next bar B so that the latter will be raised until the third bar B is reached and so on until the screen is raised as far as desired. \Vhen so raised it may be held in place by attaching the cords to any suitable stationary holding de vice. The screen is lowered by relaxing the cords I when the bars will descend and the screen open or expand by gravity.

Fig. 4 shows a modified type of the sunscreen above described. In this type, the longitudinal frame work K is not grooved and the flat bars of the screen are pulled up or down along two vertical rods pro vided one at each end side, and situated inside a space enclosed by the bar B, and an angle piece bent into 2 or any other convenient form. The upper and lower ends of these rods are seamed to the vertical frames E. E.

It is clear from the above description that the sun-screen of the present invention will afford full protection from the sun, and, at the same time, cause the air blowing against the surface of the screen to pass through the openings between the cloth strips of the screen, so that a perfect and comfortable ventilation of air into the rooms can be obtained, and while there is no danger that the screen will be flapped by the wind. Since when the wind blows hard it collides with the surface of the screen and passes into the openings, deflecting it from a direct course and thus regulating its strength to a proper degree.

While the foregoing description applies specially to a vertically arranged and adjustable screen, my improvements are not limited to such arrangement as it is obvious that my invention is applicable to laterally or horizontally disposed screens.

I claim:

1. A sun screen comprising a series of horizontal bars having angular strips or bends attached to their outer surfaces and arranged in zig-zag order, and provided with strips of cloth connecting said angular strips in vertical series and other strips of fabric connecting the bars or slats in vertical series, the strips of each series being spaced apart and the spaces between the strips of one series alternating with the spaces of the other series.

2. A sun screen, according to claim 1, in which the angular strips are adjustable in length to suit window openings of different widths.

3. A sun screen comprising a series of horizontal bars spaced apart, vertically; a series of vertical strips of cloth attached to the front of said bars and spaced apart laterally, another series of strips of cloth at;

tached to the back of said bars and spaced apart laterally, the spaces between the cloth strips of one series alternating with those of the other series.

4. In a sun screen comprising a series of horizontal bars or slats provided with angular strips arranged in zig-zag order, connectors, consisting of recessed blocks adapted to embrace the bars and angular strips and to be interlocked with the latter.

In testimony whereof I afiix my signature.

TOMOSUKE OHARA.
