Therefore, the cross section of the frame is formed in a substantially triangular shape. Such a frame is easily deformed against external pressure because the inner and outer surfaces are inclined. Therefore, this picture frame has a problem in protecting pictures and the like. In addition, there is a problem that the periphery of the painting becomes unsightly.

JP 2007-097855 A

  An object of the present invention is to provide a simple picture frame that protects a picture and the like from external pressure and that can be seen on the entire surface of the picture and the like.

  The frame of the present invention is composed of a sheet material having a single tension property composed of a polygonal base portion and a frame piece for forming a frame portion of the frame extending on each side of each. The frame piece is bent inward to form a right-angled triangle having a hollow cross section and an oblique side facing outward, and the inside of the frame portion serves as a storage portion.

  The frame piece is composed of three surfaces of a first surface portion, a second surface portion, and a third surface portion in order toward the outside, and the tip of the third surface portion is in contact with the bent portion of the base portion and the first surface portion. Is preferred.

  The sheet material is preferably paper.

  The base is preferably open at the center.

  It is preferable that an end of the frame piece is extended with a connecting piece that adheres to the inner surface of the frame piece adjacent thereto.

  The frame of the present invention is composed of a sheet material having a single tension property composed of a polygonal base portion and a frame piece for forming a frame portion of the frame extending on each side of each. The frame piece is bent inward to form a right triangle whose cross section is hollow and whose hypotenuse faces outward, and the inside of the frame portion is used as a storage portion. In other words, the frame portion has a structure in which the inner and bottom surfaces forming the L shape support the outer inclined surface. Therefore, the frame portion can be prevented from being deformed with respect to the external pressure. Therefore, this picture frame can protect the picture even if there is an external pressure on the frame portion of the storage portion.

  Moreover, since the frame is formed hollow, it has elasticity. Therefore, since the outer periphery of the painting stored in the storage portion can be crimped to the frame, it is prevented from falling. Accordingly, the painting is prevented from falling without covering the periphery, so that the entire surface of the painting can be appreciated.

  Further, the frame piece is composed of a first surface portion, a second surface portion, and a third surface portion in order toward the outside, and the tip of the third surface portion is in contact with the bent portion of the base portion and the first surface portion. The third surface portion is prevented from moving outward. Therefore, the frame portion can surely prevent the deformation with respect to the external pressure.

  Further, when the sheet material is paper, an inexpensive frame can be provided.

Further, when the center of the base portion is open, since the periphery is formed with a flange, the frame can be used as a frame with a frame covering the periphery of the painting if the front and back are reversed. In this way, the frame can be used in two forms.
The picture itself can be hung on a wall or the like, and the picture frame can be attached to the picture.

Further, when a connecting piece that adheres to an adjacent frame piece is extended at an end of the frame piece, the adjacent frame piece is bonded to the adjacent frame piece. Can be coupled and the coupled state can be reinforced. Therefore, the strength of the frame portion is further increased, so that it is possible to prevent the shape of the frame portion more reliably.
The frame of the present invention is mainly used to decorate a picture with a base such as a wooden frame or a photograph frequently seen.

It is a top view of the expansion | deployment state of the sheet | seat material before the assembly which shows one Embodiment of the frame of this invention. FIG. 2 is a perspective view of a frame formed by bending the sheet material of FIG. 1. FIG. 3 is a horizontal cross-sectional view (or vertical cross-sectional view) of a part of the frame of FIG. 4a is a perspective view of the frame of FIG. 2 with the frame reversed, and FIG. 4b is a lateral end view of FIG. 4a.

  The frame 1 (see FIG. 2) of the present invention is formed by bending a flat sheet material shown in FIG. The sheet material is made of a thin paper having a tenacity, but may be made of polypropylene or another synthetic resin in addition to the paper. Both are inexpensive and easy to carry because they are lightweight.

  As shown in FIG. 1, the sheet material is extended to the rectangular base portion 2, the frame pieces 3 extending on the respective sides around the rectangular base portion 2, and the lower portions of both ends of the upper and lower frame pieces 3. It consists of a connecting piece 4.

  The base 2 has a large opening at the center and a pedestal 5 on which a picture or the like is placed. Each frame piece 3 is composed of three surfaces of a first surface portion 6, a second surface portion 7, and a third surface portion 8 in order toward the outside, and the boundary of each surface is parallel to the edge of the base portion 2 on the back surface side. A running streak-like groove 9 is provided, and a similar groove 9 is also provided between the base 2 and the frame piece 3 (see FIG. 3). Instead of the groove 9, an intermittent hole such as a perforation line may be formed. Further, it may be a simple crease line.

  Each frame piece 3 shown in FIG. 1 is configured such that each first surface portion 6 is bent inward to be in an upright state, and ends of adjacent first surface portions 6 are brought into contact with each other so that one first surface portion 6 is bonded to the inner surface of the other first surface portion 6 and then the second surface portion 7 and the third surface portion 8 are bent inward to form a right-angled triangular frame portion 10 having a hollow cross section. And the third surface 8 is provided on the periphery of the base 2 (see FIG. 3). At this time, the tip of the third surface portion 8 is brought into contact with the bent portion 11 of the base 5 and the first surface portion 6 as shown in FIG.

  As shown in FIGS. 2 and 3, the storage portion 12 of the frame 1 formed in this way is formed by a rectangular frame-shaped base 5 and a frame portion 10 provided on the periphery thereof. The inner side of the frame portion 10 has a second surface portion 7 extending perpendicularly toward the base portion 2 and is formed into an L-shaped surface together with the bottom-side third surface portion 8 (hereinafter referred to as an L-shaped surface). The surface portion 6 is formed in an inclined state. As described above, since the tip of the third surface is in contact with the bent portion 11, the L-shaped surface itself has a corresponding strength. Therefore, deformation is prevented. Thus, since the outer inclined surface is supported by the inner L-shaped surface, as shown by the arrow in FIG. 3, the deformation of the shape is prevented even if an impact from the outside is received.

  Further, as shown in FIG. 2, the corner portions of the frame portion 10 have a strength higher than that of the intermediate portion of the frame portion 10 because the frame portions are in contact with each other at a right angle. Therefore, since the intermediate part of the frame part 10 is reinforced by both end parts, twisting and deformation are prevented.

  Further, since the base 2 has a large opening at the center, the strength is weaker than that of the base 2 which is not open, but is reinforced because the frame portion 10 surrounds the periphery. Therefore, the bottom part of the storage part 12 is prevented from being twisted and deformed. Moreover, the shape of the base 5 is also maintained. Therefore, the frame 1 maintains a stable shape without twisting or deformation even in a three-dimensional frame state after assembling as well as a sheet state before assembling. Moreover, the storage state of the picture in the storage part is stable.

  Moreover, since the inside of the accommodating part 12 is formed of the hollow frame part, as shown in FIG. 3, there is flexibility. Therefore, the painting A can be stored in close contact with the peripheral wall of the storage unit 12. Further, it can be integrated with the frame 1. That is, it is possible to attach the frame 1 to the picture A. Therefore, when the picture is moved or transferred, the picture A is dropped from the picture frame 1 because the picture A or the like can be directly supported or held from the opening of the base 2 instead of having the picture frame A. Can be prevented.

  Furthermore, since the painting A accommodated in the accommodating portion 12 is surrounded by a flexible frame portion 10, the frame portion 10 prevents direct hit. On the other hand, since the shape of the frame part 10 is stabilized when the picture A is accommodated, the picture A is more reliably protected.

  In the frame 1 of this embodiment, since the surface side of the storage portion 12 is fully open, the entire surface of the painting can be seen. It is also possible to store the painting in a state protruding from the storage port. Also, as shown in FIGS. 4a and 4b, by turning the frame 1 of FIG. 2 upside down, the pedestal 5 around the storage unit 12 can be used as a frame with a frame, instead of the frame. Is possible. In this way, this frame can be used in various ways while taking into account the design of paintings and the environment for decoration. The two-dot chain line in FIG.
