This invention relates to a connecting device for backbones, etc.

(Prior Art) Conventionally, when attaching a lattice a to a stile b or a lattice frame, as shown in FIG. As shown in Figure 11, a hole e is formed on the side of the grid a.
The method used was to open the stile b and insert a screw f through a protrusion connected to the stile b to connect the stile b. However, these methods not only require a lot of effort to tighten screws, making the assembly process inefficient, but also increase costs in the former case due to the provision of tapping holes, and in the latter case, it is necessary to process the frame and stile in addition to the lattice. There were problems such as having to do this.

As an alternative prior art means,
Publication No. 145943 describes a structure in which the mounting holes of the middle crosspiece and the upper and lower frame crosspieces are connected by fitting the protrusions formed at both ends of the central rib of the middle crosspiece connector, respectively. Publication No. 123483 discloses that a locking plate is protruded from a hole in a first crosspiece, a locking body is fixed to the end, and the locking body and the first crosspiece are inserted into the insertion part of the second crosspiece, and A device in which a locking plate provided on the body is locked inside the insertion portion is described.

However, in the former of the above prior art means, the brim of the inner crosspiece connector is exposed at the connecting portion between the inner crosspiece and the upper and lower frame crosspieces, and is visible from the outside and spoils the aesthetic appearance. In addition, in the latter case, the locking body and the first crosspiece are inserted into the insertion section of the second crosspiece, and the locking plate is locked inside the projected surface of the insertion section. There is a drawback that the locking body and the first crosspiece inserted into the locking plate are only prevented from being pulled out by the locking plate, and may fall in the opposite direction, causing rattling in the longitudinal direction.

(Problems to be solved by the invention) Therefore, this invention solves the problems of the above-mentioned known technology,
This was designed to solve this problem, and there is no need to perform any special processing on the lattice or frame to be connected, and it can be assembled quickly and reliably by simply fitting and locking the connectors, and the connection can be made quickly and securely. To obtain a robust and inexpensive connecting device that does not cause misalignment or play in surfaces.

(Means for Solving the Problem) As a means for achieving this, this invention includes a fitting part fitted into the right-angled cut end of one member, and a protrusion directly on the surface of the fitting part facing the other member. Protruding,
A part of the protrusion protrudes from the outer circumferential surface of the fitting part to form a connecting tool with the back surface of the base as a locking part, and one member connects this with a pair of opposing walls forming the outer circumferential surface. The Mitsuke wall has three walls, and a fitting storage space is provided inside the outer surface, and a fitting degree suppressing means is provided on the end surface inside the outer surface of the three walls, and the other member is viewed in the longitudinal direction. A locking hole is bored in the surface, and the fitting part of the connecting tool is fitted into the fitting part storage space of one member, and the locking part is locked to the fitting degree suppressing means, and the protruding part of the connecting tool is fitted into the fitting part storage space of one member. It is inserted into the locking hole of the other member and connected with the right-angled cut surface of one member in close contact with the projected surface of the other member.
