A holder for light-transmissive pictures in which light-transmissive pictures are arranged between a first curved foil of elastic light-transmissive material, and a second foil of elastic transparent or translucent material which is sprung into the curvature of the first foil. Bent-together ends of the first foil and the second foil have overlapping cutouts through which means for connecting the two ends may be inserted.
1. Holder for light-transmissive pictures, comprising: a first curved foil of elastic light-transmissive material; a second foil of elastic optical material sprung into the curvature of said first foil and abutting said first foil, the light-transmissive pictures being arranged between the first foil and the second foil; said first foil having bent-together ends; said second foil having bent-together ends overlapping the bent-together ends of said first foil; the bent-together ends of said first foil and of said second foil having overlying cutouts through which means for connecting said two ends are insertable.
The invention relates to a holder for light-transmissive pictures, consisting of a first curved foil of elastic light-transmissive or transparent material and a second foil of elastic light-transmissive or transparent material which is sprung into the arcuate curvature and abuts the first foil, the translucent pictures being arranged between the first foil and the second foil.
The purpose of the present invention is to provide a holder of the type mentioned in the beginning for transparent pictures, in which no separate operating step is required for connecting the bent-together opposite sides of the elastic pane.
FIGS. 1-7 illustrate the invention by way of example with respect to exemplary embodiments, but without being limited to these embodiments.
As shown in FIGS. 1-3, the cylindrical holder 18 consists of a bent first foil 9, the facing ends 7 and 8 of which overlap one another. A second foil having overlapping ends 20 and 21 is sprung into the first foil 9 having overlapping ends 7 and 8. The overlapping ends 20 and 21 of the second foil are located in the region over the overlapping ends 7 and 8 of the first foil 9. The holder 18 is provided in the region of the overlapping ends 7 and 8 of the first foil 9 respectively 20 and 21 of the second foil 19, preferably midway over the center of gravity of the holder 18, with cutouts 10 for the lamp socket 1. The lamp socket 1 is bipar tight. It consists of a cable part 2 which is placed onto the picture holder 18 at the exterior and the bulb part 4 which is located inside the holder 18. The lamp socket 1 as such and the cable part 2 as well as the bulb part 4 are produced in known per se manner and are not described because they do not belong to the invention. The cable part 2 is connected with the connecting cable 3 which carries the plug 24 at the end remote from the cable part 2. In a known manner the light bulb 25 is inserted into the bulb part 4. Cable part 2 and bulb part 4 of the lamp socket 1 are connected with one another, e.g. screwed together, in known manner. As a rule, only a screw thread for the base of the bulb 25 is provided in the bulb part 4, whereas the contacts are in the cable part 2. The juxtaposed ends of the cable part 2 and the bulb part 4 are each provided with a circumferential flange 5 respectively 6. The holder is bent from the first foil 9 and the second foil 19 in such a manner that the cutouts 10 and the overlapping ends 7 and 8 respectively 20 and 21 are in registry. Advantageously, the ends of the holder 18 which are remote from each other have rings 23 placed on them. These rings 23 are preferably of a U-shaped profile into the facing open sides of which the ends of the picture holder 18 are pushed and if desired clamped. The rings 23 are preferably produced of an elastic, e.g. metallic material. It has been found advantageous to make the rings 23 of synthetic plastic, particularly coated synthetic plastic. If the holder 18 of the first foil 9 and the second foil 19 has been bent and once the rings 23 have been put in place so that the holder 18 can no longer spring apart, then the usual lamp socket 1 is placed into the shade. In a conventional lamp socket 1, the cable part 2 and the bulb part 4 are already assembled by the manufacturer. The cable part 2 has a fixed flange 5, whereas the bulb part 2 has an external screw thread onto which a flange 6 is threaded. To assemble the holder 18 the flange 6 is unscrewed from the bulb part 4, the lamp socket 1 with the bulb part 4 is pushed from the exterior through the cutouts 10 in the first foil 9 and the second foil 19 until the flange 5 exteriorly abuts the first foil, and from the interior the flange 6 is then threaded onto the bulb part 4 until this flange 6 abuts the inside of the second foil 19. Thereupon the bulb 25 is screwed in. The edges of the cutouts 10, the cross-section of which corresponds to the end of the bulb part 4 which faces the cable part 2, are then clamped between the flanges 5 and 6. It can be advantageous to construct the cutouts 10 in the inner second foil 19 as cutouts 22 the cross-section of which corresponds to the outer diameter of the flange 6. The circumferential flange 6 then lies on the inner side of the one overlapping part 8 of the first foil 9 (FIG. 4). This embodiment has the advantage that, if desired after removal of the rings 23 and advantageously after the removal of the bulb 25, the inner second foil 19 can be squeezed together so that a gap develops between the inner second foil 19 and the outer first foil 9 and the pictures can be exchanged without having to unscrew the flange 6. In such an embodiment the overlapping ends of the two foils 9 and 19 may not be pushed into one another. The one end 8 of the first foil must abut the other end 7 and the one end 21 of the inner second foil 19 the other end 20. The first foil 9 and the second foil 19 are advantageously of an elastic material, preferably synthetic plastic. The outer first foil 9 should be of transparent material and the inner second foil 19 of translucent material.
From German Gebrauchsmuster No. 76 40 586 a holder for translucent pictures is known which is bent from two transparent or translucent foils. The holder may be bent to the form of a cylindrical lamp shade. The facing ends of the foils are connected with one another. Between the two foils translucent pictures may be placed permanently but are yet exchangeable.
