Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel device used for a room partition, a wall, and the like. More specifically, the present invention relates to a panel device used to improve the tensile strength by preventing concentration of stress and to bend at a joint. The present invention relates to a panel device capable of improving strength against directional forces, reducing the number of parts and mounting steps as much as possible to reduce costs, and increasing the engaging force simultaneously with assembly.

[0002]

2. Description of the Related Art Conventionally, partitioning of a room and construction of a wall are described in Japanese Utility Model Application No. 62-157770 (Japanese Utility Model Application Laid-Open No. 1-6).
No. 2413) is provided with a metal hook-shaped engagement connecting body as disclosed in the microfilm on one of the corresponding surface portions, and a slit-shaped engaging connection hole for connecting and engaging with this is provided on the other corresponding surface portion. The panel members are joined and connected by the connection between the engagement connection body and the locking connection hole.

However, this connection structure has the following problems. (1) As is apparent from FIG. 2 disclosed in the microfilm, the connection between the engagement connecting body and the locking connection hole is made by hooking the hook of the engagement connecting body to the thick portion of the locking connection hole. It has a structure to stop. For this reason, when a force acts in a direction in which the engaging connection body and the locking connection hole are separated from each other, that is, in a pulling direction, a stress is applied to the contact portion of the plate portion of the hole edge of the locking connection hole where the hook is hooked. And the tensile strength depends on the strength of that part.

[0004] Therefore, the edge of the locking connection hole is easily damaged unless it is made of a material having strength such as metal or the like. Therefore, the entire member in which the locking connection hole is formed is made of metal or the like. Or a metal member having a hole edge formed on the panel or the like. In the former case, the materials to be used are limited, and in the latter case, the cost is increased, such as an increase in the number of components and an increase in the number of mounting steps.

(2) The locking connection hole has a slit shape and the engagement connection body has a plate shape, and the locking connection hole and the engagement connection body are connected at a right angle to each other. Therefore, the force that bends in the direction perpendicular to the plate surface direction of the slit-shaped locking connection hole and the engagement connection body, that is, the force in the bending direction applied to the panel joint is only as strong as the plate thickness. Vulnerable.

Another conventional example is disclosed in Japanese Utility Model Application No. 52-224.
No. 48 (Japanese Utility Model Application Laid-Open No. 53-118307), a projection composed of a spherical head and a projection base formed smaller in diameter than that disclosed in the microfilm of No. 48-118307 is provided on one of the corresponding surface portions. The panel member is joined by providing a fitting portion protection plate having a fitting portion that is engaged with the fitting portion on the other corresponding surface portion, fitting the spherical head into the fitting portion, and hooking the locking portion with the locking portion of the fitting portion protection plate. Some are linked.

However, this connection structure has the following problems. (1) As is clear from the diagram disclosed in the microfilm, the connection between the projection and the locking portion has a structure in which the projection base of the spherical head is hooked to the back surface of the fitting portion protection plate. .
For this reason, when a force acts in the direction in which the projection body and the insertion part protection plate are separated, that is, in the pulling direction, stress concentrates on the abutting portion of the insertion part protection plate where the spherical head comes into contact, and the tensile strength of the insertion part protection plate is reduced. It depends on the strength of the board.

[0008] Accordingly, unless the fitting portion protection plate is made of a material having strength such as metal, it is easily broken, and therefore the entire member on which the locking portion is formed has a strength such as metal. It is necessary to make it from a material having it or to attach a metal fitting portion protection plate having a locking portion to a panel or the like. In the former case, the materials to be used are limited, and in the latter case, the cost is increased, such as an increase in the number of components and an increase in the number of mounting steps.

(2) The projection is composed of a spherical head and a projection base having a smaller diameter than the spherical head, and the projection base is connected in a state where the projection intersects the fitting portion protection plate at a right angle. doing. Therefore, the bending force applied to the panel joint is only weakened by the strength of the projection base formed with the small thickness and the diameter of the fitting portion protection plate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a panel device in which the tensile strength is improved by preventing the concentration of stress, and the strength against bending force applied to the joint is improved. It is another object of the present invention to provide a panel device in which the number of parts and the mounting process are reduced as much as possible to reduce the cost. Still another object of the present invention is to provide a panel device capable of increasing the engagement force simultaneously with the assembling.

A step 75 is formed at a boundary where the diameters are different. A wood screw 76 is inserted through the through hole 74. The screw portion 76 b protrudes from the base end surface 73 b, and the head portion 76 a is hooked at the step portion 75. The engaging projection according to this embodiment can be fixed to an appropriate place with a wood screw, so that it is effective when the mounting position of the shelf board is determined at the assembly site.

[0027]

The present invention has the above-mentioned structure and has the following effects. (1) The engagement protrusion is provided with a small-diameter portion provided at the base located on the joint surface side, a large-diameter portion provided at the front end and having a larger diameter than the base, and a small-diameter portion and a large-diameter portion. And a peripheral surface that is linearly inclined. In addition, the engagement recess is
The joining surface side is formed with a small diameter and the back wall side is formed with a large diameter, and between the joining surface side and the back wall side includes an engagement surface that is in close contact with the peripheral surface of the engagement protrusion. Then, the engagement protrusion is fitted into the engagement recess, so that the two are connected and engaged. For this reason, when a force in the direction in which the engagement protrusion and the engagement recess separate, that is, a pulling direction acts, the tensile force applied to the peripheral surface of the engagement protrusion is dispersed to the engagement surface of the engagement recess, and the stress is partially reduced. Concentration can be prevented. Therefore, the engagement concave portion can be made of a material such as wood, and the necessity of attaching a metal fitting portion protection plate to a panel or the like can be omitted. Further, the strength against the bending force applied to the joint is also improved.

(2) Since the engagement recess can be formed directly on the tree,
Costs can be reduced by minimizing the number of parts and the mounting process. (3) Since the engaging projection and the engaging recess have a dovetail structure, they are formed so that the joining force is increased simultaneously with the assembling, so that the joint does not rattle even if the dimensional accuracy is low. Can be. Further, when the panel member and the connecting column are moved away from each other, the engaging force increases, so that play and loosening of the engaging portion can be prevented, and the entire assembly can be firmly assembled.
