Description

Coupling structure for sectional furniture}

The present invention relates to a wooden furniture fitting, and more particularly, to a wooden furniture fitting which is capable of firmly holding a mounting state of a mounting member mounted on any one of a plurality of panels when a plurality of mutually orthogonal panels are assembled to each other, So that the panels can increase the orthogonal coupling force.

Generally, a panel used for wooden furniture is made of panels (MDF, PB or the like) formed by cutting a wood or compressing pulverized wood powder. In order to assemble wooden furniture made of such a panel, One member from the outside of the object to be assembled is screwed into the inner member.

However, when assembling a normal wooden furniture, since one member penetrates through the outside of the object to be assembled with the inner member, the screw is exposed to the outside of the furniture to be assembled, and thus the merchantability is deteriorated.

In addition, when a panel using wood powder or the like is used, since a large number of voids are generated between the panels, it is difficult to assemble the panel by joining the panel using screws or the like, which makes it difficult to assemble the panels. It is pointed out that the broken end is broken, and furthermore, a hole that can not be recovered is formed at the once assembled position, and it is practically impossible to reassemble after separation.

Accordingly, there has been a demand for a connecting member for an inner panel assembly that can be firmly assembled without exposing a fastening means such as a screw from the outside of a furniture assembly panel. In order to meet such a demand, An auxiliary means such as a panel coupling ring has been proposed. Such a panel coupling ring is disclosed in Japanese Patent Application Laid-Open No. 10-0358949 (published on Nov. 11, 2002) and Patent Publication No. 10-0368760 (published on Jan. 24, 2003) .

However, in the above-described prior arts, when the mounting member is mounted and fixed to the mounting groove of the panel, the fixing state of the mounting member may not be firm. Therefore, when the mounting pin is fixed to the fitting groove of the mounting member, When a plurality of panels are orthogonally coupled by inserting them into another panel, there is a structural problem in that sufficient adhesion is not established between the two members to be assembled so that the mounted members are shaken, thereby weakening the bonding force of the panels orthogonally coupled to each other there was.
