Description

34823/2 nanrco πκηο ^yn 'njian τρηη Variable picture device SUMIDA SHIKO 00., LTD. 0/ 33103 This invention related to a variable picture device.

A typical variable picture device which is frequently encountered is a perspective view device in which two different pictures are drawn on a single pleated or crude surface so that viewers can see one of two different pictures depending on the angle from which the device is looked at. However, in this type of device the angle of the device or the viewing position of viewer must be changed for the viewer to see the different pictures.

Another variable picture device, which is frequently used in advertising displays, includes a number of rotatable segments or plates. In this device it is necessary to rotate the plates through 180° to change the picture. However, these devices are often extremely large and are therefore not often used for purposes other than advertising displays.

It is an aim of the present invention to provide a variable picture device by which one of two different pictures, photographs, designs or letters, herein referred to as "pictures", may be seen in a single plane in response to a simple manipulation.

According to the present invention we provide a variable picture device comprising a fixed display assembly constituted of first and second longitudinally extending plates, each plate being unitary and formed with longitudinally spaced substantially like-shaped slits defining substantially like-shapes tongued segments, displaced out of the plane of said plates, said first and forming a f rst display, said first and second plates being interlocked in overlying relation wit individual segments of the first plate superposing predetermined corresponding segments of the second plate, and a movable display assembly constituted of a plate carrying a second display, said latter plate having a plurality of transverse sections being in a longitudinal array and sized and shaped to interleave said segments of said first and second plates of said fixed display assembly, and manually operated means for moving said movable display assembly relative to said fixed display assembly whereby said movable display assembly may be displaced to overlie the segments of said first assembly so that the display thereon may be viewed.

According to another feature of the invention, the first and second plates are of substantially the same dimension with the slits of said first plate, prior to assembly with said second; plate, being longitudinally offset with respect to the slits of the second plate, said first and second plates carrying identical fixed displays which overlie one another in said fixed display assembly.

According to a further feature, the slits in each of the first and second plates are substantially U-shapes thereby forming substantially U-shapes cut-out segments, the U-shapes segments of the first plate passing through openings formed by corresponding slits in the second plate to provide said superposed segments.

According to a still further feature, the overlying frame sections of the movable display assembly are connected at one end thereof to a cover plate having a fixed section and a section movable relative thereto between first and second positions, said fixed display assembly being carried by the fixed section of the cover plate, said movable display assembly being adhered to the movable section for movement thereby when manually moved between first and second positions.

A preferred and illustrative embodiment of the invention will now be particularly described with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of a variable picture device in accordance with the present invention, a portion of which is broken away to show the construction of picture elements; Fig. 2 is a plan view of an upper member of a fixed display assembly; Fig. 3 is a plan view similar to Fig. 2 showing a lower member of the fixed display assembly; Fig. 4 is a section of an assembly of upper and lower members as shown in Figs. 2 and 3; Fig. 5 is a section of a movable display assembly; Fig. 6 is a partially sectioned view of the fixed display assembly and the movable display assembly; Fig. 7 is a further perspective view of a variable picture device in accordance with the present invention.

Referring to the drawings, wherein like parts are indicated by like reference numerals, a variable picture or display device comprises a fixed display assembly 10 having a picture or display thereon, a movable display assembly 12 having , thereon a different picture or display from the fixed display assembly 10, and a supporting plat As best shown in Figs. 2 and 3, the fixed display assembly 10 comprises an outer longitudinally-extending <· picture plate 16 and an inner longitudinally-extending picture plate 18. Both outer and inner picture plates have a number of longitudinally spaced substantially U-shaped slits 20 defining substantially U-shapes segments 22 and 24, displaced out of the plane of the plates.

The outer and inner picture plates 16 and 18 have a similar picture display thereon forming a first display. They are interlocked in overlying relation by superimposing segments 22 on segments 24» with the segments 22 on plate 16 passing through slits 20 in plate 18. The plates are slightly offset as shown in Fig. 4 so that the picture can still be viewed in its normal form.

The thus formed fixed display assembly is fixed at its periphery to the supporting plate 14.

The fixed display assembly 10 is covered by a transparent sheet 28, which may be "cellophane" (R.T.M. ), vinyl or thelike which has a surrounding hard frame 30 of cardboard to enhance the appearance of the device. The sheet 28 and frame 30 are spaced from the supporting plate 14 by an interlayer of suitable thickness 26 , which facilitates smooth sliding operation of the movable display assembly 12.

Referring now to Fig. 5, the movable display assembly 12 comprises a number of segments in the form of transverse frame sections or strips 32 which are fixed at one end to a sliding plate 34 and extend outwardly therefore. The strips 32 each have thereon a portion of a picture and, when being fixed to plate 34, are superimposed to form a of the sliding plate 34 is bent outwardly to form a U-shaped channel 36 which is fixed to supporting plate 14· on both 'sides of line 38, where plate 14 is bent.

The strips 32 are sized and shaped to interleave segments 22, 24, and are slidably interposed between the superimposed segments 22 and 24 as best shown in Fig. 6. The picture on the fixed display assembly and that on the movable display assembly can thus be displayed alternately by simple manipulation of the sliding plate 34.

When as shown in Fig. 1, the sliding plate 34 has been pulled in the direction shown by an; arrow through a distance "1", the strips 32 are completely hidden by the overlapping segments 22 and 24, and thus complete picture on the fixed display assembly is shown. On the other hand, as shown in Fig. 7, when the plate 14 is half closed the plate 34 is moved a distance "l" in a direction away from the position shown in Fig. 1. The strips 32 now cover segments 22 and 24 andthus screen the stationary picture. The complete picture on the movable display is now displayed.

A number of the variable picture devices according to the invention may be bound to form a book, especially a book for a child.

Moreover, they can be used for educational, artistic and playing purposes.
