BEST MODE FOR CARRYING OUT THE INVENTION The structure of the present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings.

FIGS. 1 to 3 show a first embodiment of a stereoscopic photo frame constructed according to the present invention. This photo frame has a front plate 1 curved forward in an arc shape, a back plate 2 curved symmetrically in a backward direction in a bow shape, and upper and lower edges of the front plate 1 and the back plate 2 respectively. The upper surface plate 3 and the lower surface plate 4 that communicate with each other, the left and right outer side plates 5 and 6 extending rearward from the left and right edges of the front plate 1, and the back plate so that these outer side plates 5 and 6 are superposed from the inside. The left and right inner side surface plates 7 and 8 extend forward from the left and right edges of 2. The front plate 1 is provided with a rectangular window hole 9 so that the photographic panel A housed inside can be viewed from here.

The outer side plates 5 and 6 and the inner side plates 7.8 are
Both are formed in a substantially spindle shape, and are curved inward in a bow shape along the left and right edges of the front plate 1 and the back plate 2 which are concavely formed in a complementary manner. These outer side plates 5
The bases of 6 and the inner side plates 7 and 8 are foldably connected to the front plate 1 and the back plate 2, respectively, and by opening these to the outside, the front plate 1 and the back plate 2 are respectively flat-plate shaped. It is supposed to become. On the other hand, the front plate 1, the rear plate 2, the upper plate 3, and the lower plate 4
Since and are connected so that they can be bent, the photo stand can be folded flat as a whole.

From such a folded state, the outer side plates 5 and 6
When the inner side plates 7 and 8 are respectively bent inward, the front plate 1 and the rear plate 2 are curved in an arc shape and are held in the assembled state. For this reason, a locking means for holding the assembled state is unnecessary.

As shown in FIG. 2, the back plate 2 has vertical slits 1 into which the left and right ends of the photographic panel A are fitted.
A pair of 0 and 11 are opened on the left and right. Both slits 10
A rectangular hole 12 is provided between the holes 11. Below that, there is provided a support portion 13 for supporting the main body of the photo stand when it is placed on a desk or the like.

The supporting portion 13 is composed of a supporting plate 14 extending rearward from a connecting portion between the back plate 2 and the lower plate 4, and a pair of small pieces 15 projecting upward from both left and right ends of the supporting plate 14. ing. The edge of the small piece 15 that contacts the back plate 2 is
The photo stand body is formed obliquely so as to be held in a slightly tilted state. Further, the base portion of the support plate 14 with respect to the back plate 2 is further provided with a small piece 15
The base portions of the support portions 13 are foldably connected to each other, and the support portion 13 as a whole has a flat plate shape in a state of being overlapped with the back plate 2.

The vertical dimensions of the left and right slits 10 and 11 are formed to be substantially the same as the vertical dimension of the photographic panel A to be housed in the assembled state where the back plate 2 is curved in an arc shape. The inner portions of the ends of the photographic panel A, into which the left and right ends are fitted in the slits 10 and 11, are engaged with the upper and lower corners 16 inside the slits 10 and 11.
On the other hand, at the center of the opening edge on the outside of the slits 10 and 11 with which the outside portion of the end of the photographic panel A abuts, the back plate 2 is curved in an arc shape, and therefore, is located rearward of the corner portion 16. positioned. Therefore, the photographic panel A is supported by the slits 10 and 11 while being curved in a convex shape.

As described above, the photographic panel A has the slit 1
It is held in a convexly curved state by being supported by a total of six support points, three on each of the left and right sides of the upper and lower corners 16 of 0 · 11 and the center of the outer opening edge of the slits 10 · 11. However, when it is assembled from the folded state, it may come into contact with the back plate 2 and be curved in a bow shape rearward. In this case, by pressing the back surface of the photographic panel A from the hole 12, it can be deformed into a predetermined convex shape that is curved forward in a convex shape.

In this way, the photo panel A is attached to the photo frame.
1 is viewed from the front side through the window hole 9 as shown in FIG. 1, and is viewed as a three-dimensional photograph with a depth that cannot be obtained from a flat-shaped photograph due to the perspective difference generated from the curved surface. can do. When not in use, the left and right outer side plates 5 and 6 and the inner side plates 7 and 8 as described above.
By sequentially opening the photo panels to the outside, the photo frame as a whole can be folded flat while the photo panel A is accommodated.

If the photographic panel A has a sufficient resilience, the photographic panel A is pressed into contact with the supporting points of the slits 10 and 11 to be firmly bonded and held. Although it is not necessary to support the lower end side of the photographic panel A, when the elastic force is insufficient, the slits 10 and 11 are formed so as to contact the lower surface plate 4, and the lower end of the convexly curved photographic panel A is the lower surface plate. It may be configured to abut the inner surface of No. 4.

In the present embodiment, the upper plate 3 and the lower plate 4 are provided so that the upper and lower edges of the front plate 1 and the rear plate 2 are connected to each other. It is also possible to directly connect the upper and lower edges of the front plate 1 and the rear plate 2 without providing them and to have a spindle-shaped cross section with sharp upper and lower ends. In this case, if necessary to support the lower end side of the photographic panel A, a shelf-shaped plate member may be extended inside from the front plate 1 or the rear plate 2.

Further, in this embodiment, the front plate 1
Also, the left and right edges of the back plate 2 are both recessed in a bow shape, and the left and right outer side plates 5 and 6 and the inner side plate 7
Although 8 is connected, for example, the outer side plates 5 and 6 may be eliminated and the left and right edges of the front plate 1 may be formed straight. Even in this case, if the front plate 1 is formed of a flat plate material having elasticity, the front ends of the left and right inner side plates 7 and 8 and the back surface of the front plate 1 are elastic by bending the front plate 1 in an arc shape. Since both of them spontaneously come into pressure contact with each other to firmly bond the two, the entire photo frame is firmly held in the assembled state without providing any locking means.

4 and 5 show a second embodiment of a stereoscopic photo stand constructed according to the present invention. This photo frame is composed of a flat plate-shaped front plate 22 in which a rectangular window hole 21 is opened and a rear plate 23 which is curved backward in a bow shape.

Similar to the back plate 2 shown in the above-described first embodiment, the back plate 23 has a pair of vertical slits 24 and 25 into which the left and right ends of the photographic panel A are fitted. The photographic panel A is held in a convexly curved state here (see FIG. 2). A rectangular hole 26 is formed between the left and right slits 24 and 25.

In this photo stand, the back plate 23 is made of a flexible plate material and, for example, the back plate 2 is used.
If the upper end of 3 is foldably connected to the upper end of the front plate 22 and the lower end of the back plate 23 is detachably connected to the lower end of the front plate 22, it can be made foldable.

Further, the mirror-finished plate, which has been mirror-finished by attaching a reflection sheet to the inside, is provided with a photographic panel A at the front end from the left and right opening edges of the window hole 21 on the back surface of the front plate 22.
A pair may be extended obliquely rearward so as to abut. In this way, when the left and right peripheral portions of the photographic panel A are projected on the left and right mirror surface plates when viewed from the front side through the window hole 21, a sense of expanse in the left and right is obtained, and a stereoscopic effect is emphasized. be able to. Further, if the bases of the left and right mirror surface plates are foldably connected to the back surface of the front plate 22, there will be no hindrance to folding when the photo stand is configured to be foldable as described above. can do.

In each of the above embodiments, the photographic panel A is sandwiched between two transparent sheets having a predetermined elastic force, and then the slits 10 and 11 or the slits 24 are formed.
-It may be inserted into 25. By doing so, it becomes possible to preferably hold various types of photographs of different sizes and materials.

EXAMPLE The three-dimensional photo stand shown as the above-described first embodiment can be formed from one sheet of paper made by cutting thick paper. FIG. 6 is an expanded view of an example of the paper pattern of this photo frame. First, each connecting portion of the lower surface plate 4, the front surface plate 1, the upper surface plate 3, the rear surface plate 2 and the sticking portion 31 is bent along a broken line shown by a broken line in the drawing to form a tubular shape of the lower surface plate 4. The adhesive portion 31 is adhered to the inner surface. With this, the folded state is obtained, and then the inner side plates 7 and 8 and the outer side plates 5 and 6 are sequentially bent inward along the fold line to obtain the assembled state shown in FIG. Support portion 13 extending from the bottom plate 4
Also, by folding along the fold line, a predetermined assembled state is achieved.

[0024]

As described above, according to the present invention, a photograph can be retained in a convex shape with an extremely simple structure in which a pair of slits are provided on the left and right sides of a back plate curved in an arc shape. In addition, it is easy to manufacture and can be mass-produced at low cost, which is extremely effective in reducing the manufacturing cost of the three-dimensional photo stand. In addition, since the structure can be easily folded and the internal photograph does not hinder the folding, the photograph can be folded while being stored. Therefore, handling at the time of packaging, transportation, storage, etc. becomes easy and convenience can be improved.

In particular, if a spindle-shaped side plate is provided in order to keep the back plate curved in an arc shape, the structure is simple, and the photograph is assembled into a convex shape and a flat shape. It is easy to change the form between the folded state and
Moreover, the assembled state can be firmly and stably maintained. Moreover, since the side plate serves as a lid that closes the opening at the side of the tubular body including the front plate and the back plate, there is an advantage that the appearance of the photo stand is improved.
