Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plate provided on the back side of a frame.

[0002]

[Prior art]

 A normal frame is one in which the frame part of the frame is attached to the periphery of the back plate.This back plate is designed so that the frame part of the frame that forms a certain shape does not deform its shape. It is provided to prevent wrinkles from appearing in the paintings or photographs in the interior, and it is required to have appropriate strength for that purpose. Since it is required to be lightweight because it does not become a problem, traditional wooden boards have been used exclusively for conventional back plates.

[0003]

[Problems to be solved by the device]

 However, in the case of a back plate made of wooden plate material as described above, if the thickness is reduced by focusing on weight reduction, it is possible to maintain the strength that does not deform the frame part of the frame. However, a certain amount of wall thickness is indispensable in order to retain the appropriate strength, and in order to retain that strength, the minimum weight must be accepted, and therefore, in a large frame. It had to be heavy.

Further, in recent years, felling of natural trees has become an international environmental problem, and under such circumstances, it has been eagerly desired to change the wooden products from the conventional ones to other materials. Was there. In view of the above points, the present invention aims to reduce the total weight of the frame and to help protect natural wood by making it possible to form the back plate of the frame with paper. It is a thing.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a first reinforced paper material in which thin-walled paper materials are curved at equal intervals and alternately in a direction parallel to a predetermined first direction, A second reinforced paper material formed by curving thin paper materials at equal intervals and alternating directions at positions parallel to the second direction orthogonal to the first direction; When the second reinforcing paper material is pasted, a flat plate-shaped intermediate paper material that assists the adhesion between the two and the surface of the first reinforcing paper material that is not the side to be adhered to the intermediate paper material. Of the second reinforcing paper material and the back surface material of the second reinforcing paper material that does not adhere to the intermediate paper material.

[0006]

[Action]

 With the above-mentioned structure, the first reinforced paper material and the second reinforced paper material are attached between the front surface paper material and the intermediate paper material or between the back surface paper material and the intermediate paper material. Since the first and second reinforced paper materials are curved along a certain direction, the first reinforced paper material has the maximum rigidity against bending in the second direction. The second reinforced paper material has the maximum rigidity against bending in the first direction, and can have sufficient strength as the back plate of the frame.

Further, the entire back plate is composed of a first reinforced paper material, a second reinforced paper material, an intermediate paper material, a front surface paper material and a back surface paper material, all of which are paper materials. Therefore, the amount is extremely light, and by using recycled paper, it is possible to manufacture without using natural wood.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. The present invention relates to a back plate 1 provided on the back side of a frame A as shown in FIGS. 1 and 2, and includes two reinforcing paper materials 2, 3, an intermediate paper material 4, a surface paper material 5 and The back side is made of paper material 6.

Therefore, as shown in FIGS. 2 and 3, the first reinforced paper material 2 is curved at positions 7, 8, ... 9, 10 parallel to the first direction a. The curving direction alternates up and down. The second reinforced paper material 3 is curved at positions 11, 12, ... 13, 14 that are orthogonal to the first direction a and are parallel to the second direction b. It alternates up and down. An intermediate paper material 4 is provided between the first reinforced paper material 2 and the second reinforced paper material 3, and the first reinforced paper material 2 is attached to the upper side surface 15 of the intermediate paper material 4. By attaching the second reinforced paper material 3 to the lower side surface 16, the surface area of the first reinforced paper material 2 and the second reinforced paper material 3 that can be attached can be increased. Therefore, the two reinforcing paper materials 2 and 3 can be firmly attached to each other. A front surface paper material 5 is attached to the upper side of the first reinforcing paper material 2 to form the surface of the back plate 1, and a back surface paper material 6 is provided to the lower side of the second reinforcing paper material 3. Are attached to form the back surface of the back plate 1.

The first reinforced paper material 2 has a position 17 parallel to the second direction b due to the presence of curved portions at positions 7, 8, ..., 9 parallel to the first direction a. Has the maximum rigidity against bending, while the second reinforced paper material 3 has curved portions at positions 11, 12, ... 13, 14 parallel to the second direction b. By virtue of the existence of, the maximum rigidity is obtained for bending at the position 18 parallel to the first direction a. Therefore, even when bending is performed at the position 19 parallel to the direction c having an angle with respect to the first direction a, the force to bend is in the first direction a and the second direction b. Since it is disassembled and supported by the curved portions of the first reinforced paper material 2 and the second reinforced paper material 3, it has sufficient rigidity.

As the front surface paper material 5 and the back surface paper material 6, flat sheets are used, but this requires the back plate 1 to be flat as a basis for keeping a painting or the like in a flat state. That it is not enough to attach both the reinforcing paper materials 2 and 3 to the intermediate paper material 4 and that the concentrated load acts on a part of the reinforcing paper materials 2 and 3. It is provided because the load can be dispersed at times.

As shown in FIG. 4, two intermediate paper materials 20 and 21 are provided, and the surface paper material 5 is attached to the upper side of the first reinforcing paper material 2 and the intermediate paper material 20 is attached to the lower side. And a second plate member 23 formed by sticking the intermediate paper member 21 on the upper side of the second reinforced paper member 3 and the back surface paper member 6 on the lower side thereof. A back plate similar to that described above can also be obtained by bonding the intermediate paper material 20 of the first plate material 22 and the intermediate paper material 21 of the second plate material.

[0013]

【effect】

 As described above, the present invention has the first reinforced paper material having the curved portion parallel to the first direction and the second reinforced paper material having the curved portion parallel to the second direction, Moreover, since the first direction and the second direction are orthogonal to each other, the back plate of the frame can have the necessary strength.

Moreover, the back plate is made of the first reinforced paper material, the second reinforced paper material, the intermediate paper material, the front surface paper material, and the back surface paper material, and since it is made of all paper materials, it is extremely lightweight, Furthermore, by using recycled paper, not only is it very cheap, but it can be manufactured without using natural wood. Also, when you want to write a simple item such as the date and place where the photo was taken on the back plate, such as when using a frame on a table to decorate the photo, the back plate is made of paper material. Therefore, it can be written in pencil and can be easily rewritten when exchanging photographs.

A frame for hanging on a wall may be left on the wall for many years, and the back plate may be heavily soiled with dust or the like, and such soiling may not be easily removed. Since the back plate according to the present invention can be manufactured at a very low cost, it is possible to periodically replace only the back plate by preparing several kinds having different sizes.
