DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for mounting, for example, a leg on a table top, and a top plate, a shelf plate, and a ground plate on a furniture side plate.

[0002]

2. Description of the Related Art Conventionally, as a mounting device of this type, for example, a configuration described in Japanese Patent Application Laid-Open No. 7-155225 has been known.

In the mounting device described in Japanese Patent Application Laid-Open No. Hei 7-155225, a bolt having a tapered engagement surface on a head portion is projected from a joint surface of a leg of a table as a mounting body.
A mounting hole for inserting the head of the bolt is formed in the joint surface of the table top plate, which is the mounting object, and a tapered engaging surface is engaged with one side of the opening edge of the mounting hole facing the opening. While forming an engaging surface, a screw hole and a stopper fitting mounting portion having a tapered surface expanded downward on its peripheral surface are provided on the other side, and a bolt insertion hole communicating with the screw hole in the stopper fitting mounting portion is provided. A stopper having a contact surface that contacts the tapered surface is provided, and a fixing bolt that is screwed from a bolt insertion hole of the stopper to a screw hole is provided.

Then, the fixing bolt is screwed into the screw hole from the bolt insertion hole of the stopper fitting and tightened, so that the contact surface of the stopper comes into contact with the tapered surface of the stopper mounting portion, and the taper is stopped by this tapered surface. While the metal fitting is being moved laterally, the metal fitting is fitted to the metal fitting mounting part, and the bolt is pushed by the metal fitting, and the tapered engagement surface of the bolt head extends along the engaged surface. The bolt is pulled up on the engaged surface while being moved, and the joint surface of the leg provided with the bolt is joined to the joint surface of the top plate, and the leg is attached to the top plate.

However, in the mounting device described in Japanese Patent Application Laid-Open No. Hei 7-155225, the bolt protruding from the leg is laterally moved by tightening the retaining bracket to the retaining bracket mounting portion with the fixing bolt. There is a possibility that the leg may be attached to a position shifted from an appropriate position on the top plate due to the amount of fastening of the fixing bolt to be fastened to the retaining fitting attaching portion.

That is, in recent years, there has been a demand for mounting the leg in such a manner that the outer peripheral surface of the leg coincides with the peripheral edge of the top plate. However, in a configuration in which a bolt protruding from the leg is laterally moved,
The outer peripheral surface of the leg is displaced inward from the periphery of the top plate,
The peripheral edge of the top plate and the outer peripheral surface of the leg are likely to be displaced such that the outer peripheral surface of the leg protrudes outward from the peripheral edge of the top plate and is displaced.

For this reason, especially when the outer diameter of the leg is large, the outer peripheral surface of the leg is likely to protrude toward the operation side of the fixing bolt. There is a case where it is difficult to rotate the fixing bolt by contacting the surface.

Further, since the number of components required for attaching the legs to the top plate is large, the configuration becomes complicated, and it is not easy to improve the manufacturability.

Therefore, conventionally, for example, Japanese Patent Application Laid-Open No. 10-179
The configuration described in Japanese Patent Publication No. 297 is known.

The mounting device described in Japanese Patent Application Laid-Open No. H10-179297 is provided with a gear interlocking mechanism in which a plurality of gears are sequentially rotatably meshed with each other.
It is embedded in the joint surface on the lower surface of the tabletop. The gear at the input end of the gear interlocking mechanism is formed with an insertion portion as a tightening operation portion into which the tip of a hexagon wrench can be inserted. A nut portion having a thread groove is formed on the inner peripheral portion. Further, a bolt that is screwed into a nut portion of the gear interlocking mechanism is protruded from a joint surface of the leg of the table.

When the legs are mounted on the table top using this mounting device, first, the nut of the gear interlocking mechanism mounted on the table and the bolts of the legs are screwed together. After the positioning, the tip of the hexagon wrench is inserted into the insertion portion of the gear on the input end side, which is the tightening operation portion.

Next, the gears on the input end side are rotated by the hexagonal wrench to sequentially rotate the respective gears. Then
When the gear located on the output end side rotates, the nut and the bolt of this gear are screwed together. further. By rotating the gear on the input end side, the nut is fastened to the bolt, and the top plate and the leg are joined at each joint surface.

[0013]

However, in the mounting device described in Japanese Patent Application Laid-Open No. H10-179297, when the legs are mounted on the top plate of the table, the rotation of the gear on the output end side of the gear interlocking mechanism is required. Accordingly, there is a possibility that the entire leg rotates around the bolt. For this reason, when attaching the leg to the top plate, it is necessary to hold down the leg, and the work of attaching the leg to the top plate is not easy, and there is a problem in usability.

Further, since each gear constituting the gear interlocking mechanism has a different shape, when forming the gear interlocking mechanism, it is necessary to form each gear, so that the productivity is not very good. Have a problem.
