SUMMARY OF THE INVENTION According to the present invention, there is provided a folding apparatus for holding a flat photograph in a state of being convexly curved forward, and for flattening back and forth when not in use. A stereoscopic photo stand, in which a pair of side plates are provided on the left and right sides of the photo, and between the left and right side plates, upper and lower frame plates along the front of the photo, and shorter than the frame plate, on the back side of the photo. A back plate to be arranged is erected and both ends are flexibly connected to each other, and the left and right side plates are bent at a predetermined opening angle with respect to the back plate. When the bending is restored, the upper and lower frame plates and the photograph are flattened on the back plate side to be foldable, and the side plates are held at a predetermined opening angle between the left and right side plates. Characterized by the provision of a detachable locking holding means It is achieved by providing a folding stereoscopic picture frame. In this case, in order to make the upper and lower frame plates and the back plate come into contact with the front and back sides of the photograph in a folded state to form a flat plate, the sum of the distances between the connection portions of the frame plate and the back plate on the left and right side plates is required. It is sufficient that the lateral dimension of the back plate is shorter than the circumferential dimension of the frame plate by an amount corresponding to.

In particular, it is preferable to provide a mirror surface on the inner surface of each of the left and right side plates. Thereby, the left and right peripheral portions of the photograph displayed through the window holes between the upper and lower frame plates are reflected on the mirror surfaces of the left and right side plates, so that the photograph can be viewed as a photograph having a sense of spreading to the left and right.

In addition to the above, each of the left and right side plates is provided with a leg protruding rearward, and a stay plate serving as the locking and holding means for holding a space between the left and right leg portions is raised and lowered on the back plate. It is good to provide freely. As a result, since the left and right legs support the photo stand in a predetermined upright state, there is no need to provide a separate support leg, and it is possible to suppress an increase in the number of constituent members, and it is not necessary to perform an up and down operation of the support leg. Therefore, the folding and assembling operations can be simplified. In addition, a stay plate is inserted between the left and right leg parts urged by the elastic force due to the flat upper and lower frame plates and the photo that curves forward in a convex shape to regulate the movement of the left and right side plates. ,
The left and right side plates are stably held in an assembled state forming a predetermined opening angle.

Further, the left and right side plates are formed at left and right ends of a plate member having a predetermined shape, and the upper and lower frame plates are formed at upper and lower ends of the pattern, respectively, and a left and right cut is formed at a portion between the upper and lower frame plates. Into the upper and lower three back plates, the portion between the middle and lower two back plates is separated to the left and right to form a pair of the left and right legs, between the upper and middle two back plates The portion may be cut and raised rearward to form the stay plate. Thus, a photo stand can be manufactured only by making predetermined cuts and folds in a single sheet of board or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below based on embodiments shown in the accompanying drawings.

FIG. 1 to FIG. 4 show a first embodiment of a folding stereoscopic picture frame constructed according to the present invention. The photo stand 1 has side plates 2 and 3 arranged in a pair on the left and right at a predetermined opening angle, and is laterally erected in a state in which the left and right side plates 2 and 3 are curved forward and convex so as to be connected to each other. The upper and lower frame plates 4,5, and three upper, middle, and lower back plates 6,7,8, which are provided between the left and right side plates 2,3 behind the upper and lower frame plates 4,5, Photo Panel A
Is accommodated in a state of being curved in a convex shape forward along the upper and lower frame plates 4 and 5, and viewed from the window hole 9 defined by the left and right side plates 2 and 3 and the upper and lower frame plates 4 and 5. Is available.

The outer side edges of the upper and lower frame plates 4 and 5 are formed straight and continuous with the upper and lower edges of the left and right side plates 2 and 3 in a front view. The inner side edge is formed in an arc (see FIG. 3). On the inner surfaces of the left and right side plates 2 and 3, a pair of arcuate mirror surfaces 10 having arcs on the outside are formed symmetrically. Also, left and right side plates 2
3 is provided with a pair of left and right edge plates 11 and 12 that extend outward in parallel with the back plates 6, 7 and 8. The left and right edge plates 11 and 12 are formed in an arc shape having an arc on the outside, and their bases are left and right side plates 2 and 3 respectively.
Are foldably connected to the

The upper and lower frame plates 4, 5 and the upper, middle, and lower back plates 6, 7, 8 are provided at right and left sides of the left and right side plates 2 at predetermined intervals.
3 and the frame plate 4 in the side plates 2 and 3.
The distance in the front-rear direction of each connecting portion of the back plates 6, 7, and 8 substantially matches the value obtained by subtracting the width of the back plates 6, 7, 8 from the circumferential size of the frame plates 4, 5. It is set as follows.
The upper and lower frame plates 4 and 5 and the upper, middle and lower back plates 6 and 7
The left and right ends of 8 are connected to the left and right side plates 2 and 3 so as to be freely bent.

As shown in FIG. 2, the left and right side plates 2 and 3 are provided with legs 13 for holding the photo stand 1 in an upright state when placed on a desk or the like in a manner projecting rearward. The photo frame 1 is held in a state in which the photo frame 1 is tilted backward at a predetermined angle. At the upper edge of the middle back plate 7, a stay plate 14 projects downward and rearward, and the left and right side plates 2.
3 is provided so as to be fitted between the legs 13. The base of the stay plate 14 is connected to the middle back plate 7 so as to be freely bent.

The lateral dimensions of the upper and lower frame plates 4 and 5 are substantially equal to the lateral dimensions of the photographic panel A to be accommodated, and the left and right end faces of the photographic panel A are abutted by the left and right side plates 2.3. On the other hand, the front of the upper and lower ends of the photo panel A is
The photographic panel A is curved in a convex shape in close contact with the back surface of the upper and lower frame plates 4 and 5 and the left and right side plates 2 and 3 with the elasticity of the curved and deformed photographic panel A itself. The photographic panel A is held by the photographic frame 1 by pressing. Therefore, the photographic panel A can be easily replaced by inserting and removing the photographic panel A between the frame plates 4 and 5 and the back plates 6, 7 and 8 from above or below.

In the photo stand 1 thus constructed,
When viewed from the front side, it can be viewed as a three-dimensional photograph having a depth that cannot be obtained in a flat-plate-like photograph due to the perspective difference caused by the convex curved surface of the photographic panel A. The left and right peripheral portions of the photo panel A are mirror surfaces 1 of the side plates 2.3.
Since the image is projected at 0, it can be viewed as a photograph having a feeling of spreading to the left and right. In particular, the photographic panel A itself displayed through the window hole 9 between the upper and lower frame plates 4 and 5 and the reflected images reflected on the left and right peripheral portions and projected on the left and right mirror portions 10 are united to form the whole. , A rounded image is displayed in the vertical and horizontal directions. In addition, the left and right edge plates 11 and 12 serve as frames to create a sense of thickness in the photo frame 1, and furthermore, since the photo panel A is disposed deeper than that, a sense of depth is generated and the three-dimensional effect is enhanced.

To fold the photo stand 1,
It is sufficient that the left and right side plates 2 and 3 are opened outward after the upper and lower plates 4 are pivoted upward to be separated from the legs 13 of the left and right side plates 2 and 3. Then, the back plate 6, 7.8, the holding plate 14, which has entered between the upper and middle back plates 6, 7, and the leg portion 13 of the side plate 2, 3, enter between the upper and lower frame plates 4, 5. Thus, the entire photo stand 1 is folded into a flat plate shape. At this time, if the elasticity of the curved frame plates 4 and 5 and the photographic panel A is relatively large, it is only necessary to remove the stay plate 14 from between the two leg portions 13 of the left and right side plates 2 and 3. 5 and the photographic panel A are resiliently restored, and the photographic frame 1 is automatically flattened accordingly, and the folding operation is simplified. In this folding operation, the photo panel A housed inside is flattened as the side plates 2 and 3 are opened, and does not hinder the folding operation, so that the photo panel A can be folded with the photo panel A housed therein. Storage and transportation during use can be performed with the photographic panel A housed.

On the other hand, in order to return from such a flat folded state to the assembled state shown in FIG. 1, while turning the left and right side plates 2 and 3 inward, the retaining plate 14 is raised to raise the left and right side plates 2.・ It is sufficient to fit between both legs 13 of 3. At this time, the left and right side plates 2 and 3 are urged to open outward by the resilience of the flat upper and lower frame plates 4 and 5 and the photographic panel A by bending. Leg 13
The left and right side plates 2 and 3 are provided by the retaining plate 14 inserted between them.
Is regulated, and is stably held in the assembled state.

Incidentally, the present photo stand 1 can be formed from one sheet of paper obtained by cutting thick paper. FIG.
Shows an example of the pattern of the photo stand developed.
Mirror surfaces 10 are formed on the left and right side plates 2 and 3 by attaching a reflection sheet or the like. Thus, the connection state is already folded, and when each connecting portion is bent in a predetermined direction along a broken line shown by a broken line in the figure, an assembly state shown in FIG. 1 is obtained. In this case, there is no portion that needs to be adhered except for the formation of the mirror surface portion 10. Note that another thick paper may be attached to the leg portions 13 of the side plates 2 and 3 to increase rigidity.

In this embodiment, the photographic panel A is held by the photo stand 1 by the elasticity of the photographic panel A itself that has been curved and deformed. However, the photographic panel A is thin and easily bent, and cannot be mounted properly. In the case, the upper and lower frame plates 4
It is preferable that a projection is provided on the back surface of 5 to lock the upper and lower edges of the photographic panel A so as to prevent the photographic panel A from being displaced or falling off. Further, a flexible transparent plate such as a plastic sheet may be provided in the window 9 between the upper and lower frame plates 4 and 5. At this time, by using a flat plate having high elasticity as the transparent plate, an elastic force due to the elastic deformation of the transparent plate is added, and the assembled state of the photo stand 1 is firmly maintained.
