Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a support structure for axially supporting a door panel made of a plastic hollow body.

[Prior Art] Conventionally, door panels made of hard plastic hollow bodies have been widely used in lockers and other furniture, fixtures, buildings, etc. The shaft support structure has brackets on the upper and lower parts of the back wall of the door panel. The shaft supporting members such as the above are brought into contact with each other and fixed by bolts or the like.

[Problems to be Solved by the Invention] By the way, in a door panel, a load due to its weight is applied to a shaft supporting portion, but like a conventional shaft supporting structure,
In the structure where the shaft support member is in contact with the back wall surface and is simply fixed with bolts, etc., the load concentrates only on the fixed parts such as bolts and is easily damaged, and the strength of the shaft support structure is low and the durability is poor. there were.

The present invention has been made in view of the above-mentioned drawbacks of the conventional ones.
A concave portion having two curved surfaces is formed on a part of a wall surface forming the hollow body, and engaging portions of a shaft supporting member having a shape corresponding to those surfaces are formed, and the shaft is provided between the engaging portions. By engaging the support member and fixing it to at least one of the two curved surfaces with bolts or the like, the load due to the weight of the door panel is dispersed so that it is not concentrated on a part of the shaft support member, and thus the load is excessive. It is an object of the present invention to provide a support structure for a door panel that can improve durability by eliminating partial damage and the like due to excessive concentration.

[Means for Solving the Problems] The present invention has the following constitutions as technical means for achieving the object.

That is, the structure is such that in a shaft support structure for a door panel made of a hollow plastic body, a concave portion having two vertical bending surfaces is formed on a part of a wall surface forming the hollow body, and the two bending surfaces of the concave portion are formed. Each has an engaging portion of a shaft supporting member having a shape corresponding to that surface, and the shaft supporting member is engaged between the engaging portions and is fixed to at least one of the two bent surfaces with a bolt or the like. This is a support structure for a door panel characterized by the above.

[Operation] In the support structure for a door panel according to the present invention, a concave portion having two vertical bending surfaces is formed in a part of a wall surface forming a hollow body, and the shaft support member engaged with the concave portion causes the concave portion to be formed. The load due to the weight of the door panel is received.
For this reason, the load due to the weight of the door panel is not concentrated on a part of the shaft support member but is widely dispersed and received, avoiding excessive concentration of the load and preventing damage to the shaft support portion. Further, the strength of the shaft supporting portion is improved.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 is a locker, and a door panel 2 is attached to the locker 1 so as to be openable and closable. 3 is the handle.

As shown in FIGS. 2 to 4, the door panel 2 of the locker 1 is made of a hollow plastic body formed by blow molding a hard thermoplastic such as styrene-modified polyphenylene oxide. The front surface of the back wall 4 is recessed so as to be framed on the back side, and the upper and lower parts of the back wall 4 are partially bent in the vertical direction.
A concave portion 7 having 6 is formed, locking portions 10 and 11 are formed on the upper edge 8 and the lower edge 9 of the two curved surfaces 5 and 6, and an insert is formed on one surface 5 of the two curved surfaces. Nut 12 is inserted. Reference numeral 13 is a shaft support member.
A surface 13 has a surface 14 that contacts one surface 5 of the two bent surfaces and a surface 15 that corresponds to the other surface 6 of the two bent surfaces, and that contacts the surface of the back wall 4 below the surface 6. The shaft support member 13 has a bent shape and has a bolt insertion hole 17 on the surface 14 and another surface 15 has an insertion hole 20 for the shaft pin 19 of the shaft member 18. The shaft member 18 is fixed to the body side of the rocker 1. The shaft support member 13 has its surfaces 14 and 15 bent to form two surfaces 5 and 6.
To the corresponding engaging portions 10 and 11, and the surface 14 is fixed by fastening the bolt 21 to the insert nut 12. 22 is the front wall of the door panel 2.

According to the support structure of the door panel 2 configured as described above, the shaft support member 13 is locked to the locking portions 10 and 11 of the recessed portion 7 so as to be orthogonal to the load direction and is fixed by the bolt 21. Since the load due to the weight of the door panel 2 is received by the entire shaft support member 13, the load is not excessively concentrated on a part of the shaft support member 13, and the load is distributed. Therefore, there is no possibility of damaging the shaft supporting portion, and the strength thereof is significantly increased.

[Advantages of the Invention] The present invention, in a shaft support structure for a door panel made of a hollow plastic body, forms a concave portion having two vertical bending surfaces in a part of a wall surface forming the hollow body, and the concave portion of the concave portion is formed. Engaging portions of the shaft support member having a shape corresponding to the surface are formed on the two bent surfaces, and the shaft support member is engaged between the engaging portions, and at least one of the two bent surfaces is bolted. The load due to the weight of the door panel is distributed so that it is not concentrated on a part of the shaft support member, so partial damage due to excessive concentration of load is eliminated and durability is improved. There is an effect that can be achieved.
