DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel which can be used as a top panel such as a desk or table, a partition panel, and the like.

[0002]

2. Description of the Related Art Conventionally, as a configuration of a panel having a flat shape having a curved portion in a part applied to a top plate such as a desk or a table, a panel formed entirely of one sheet material,
There are a type having a flash structure in which face materials are attached to both upper and lower surfaces of a core material, and a type formed by joining an auxiliary top plate having a curved portion to a rectangular panel main body.

[0003]

However, since a panel formed entirely of a single plate is formed by directly shaving a panel from a muk plate or the like with a router or the like, the structure is simple, but the material cost is high. Moreover, there is a disadvantage that the completed panel is very heavy. On the other hand, the thing of the flash structure combines wooden perch square wood etc. so as to include the outer shape of the panel, making a joist to reinforce the peripheral part of the panel,
A light-weight core material such as a paper core is disposed in a gap inside the joist material to form a core material, and a surface material and a back surface material are stuck on both upper and lower surfaces of the core material, and then a predetermined panel shape is formed. The joist and the front and back materials are cut by a router or the like. For this reason, the panel can be lightened as much as the paper core can be used.However, it is necessary to accurately assemble the joist along the outer shape of the panel. There is a drawback in that the more complicated the shape of the panel, the more troublesome and costly it is to manufacture, for example, it is necessary to include the portion.

[0004] When an auxiliary top plate having a curved portion is joined to a rectangular panel main body, the joint between the panel main body and the auxiliary top plate is particularly vulnerable to an overload, and the effective top plate strength is obtained. Is difficult to secure.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a structure in which a reinforcing material having a shape substantially corresponding to a plane shape including a bending portion is sandwiched between the bending portions on both upper and lower surfaces thereof. A pair of steel plates each having a bent portion formed in a direction approaching to each other is provided along substantially the entire periphery including the periphery thereof, thereby providing a high-strength panel with a simple configuration.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, a panel according to the present invention has a planar shape partially having a curved portion, and a reinforcing member having a shape substantially corresponding to the planar shape including the curved portion; A pair of steel plates which are provided on both upper and lower surfaces so as to sandwich the reinforcing material and form bent portions in directions approaching each other over substantially the entire periphery including the curved portion. It becomes.

[0007] According to this structure, it is possible to cut the reinforcing material such as paper core and the like, and to attach and join the steel sheet subjected to the edge processing such as the bending process on both upper and lower surfaces. Compared with the case of using, a high-grade material is not required, and processing effort such as shaving of a Muku material is not required, and it is possible to easily cope with a light and various panel shape. Also, compared to a case where an auxiliary top plate having a curved portion is joined to a rectangular panel body,
Since the whole is united and the bent portion is formed on substantially the entire periphery of the edge, there is little bending that is strong against bending load and overload, and effective top plate strength can be secured.

Further, as a preferable mounting structure of the edge member, a structure in which the edge member is sandwiched between bent portions of upper and lower steel plates can be cited. With this configuration, since the steel plate also serves as the means for attaching the edge member, compared to a structure in which a groove is formed in the panel body and the edge member is driven in or a structure in which the edge member is fastened to the panel body using screws, No special fastening means is required, and the edge member can be attached at the same time when the panel body is made, so that the number of manufacturing steps can be greatly reduced.

Further, as a specific mounting structure of the edge member in this case, there is a structure in which grooves are provided on upper and lower surfaces on the base end side of the edge member, and a bent portion of a steel plate is engaged with these grooves. In order to easily adapt the edge member corresponding to the curved portion to various panel shapes and to provide an extremely good attachment state, the edge member corresponding to the curved portion should be soft. It is desirable to use one made of resin.

In order to further improve the appearance of the panel, it is desirable to attach a decorative plate on the upper surface of the upper steel plate.
