Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal fitting that securely and adjustably joins two orthogonal members.

The present invention will be explained below based on the illustrated embodiments.

In the figure, 1 is one member to be joined in the orthogonal direction, and 2 is the other member, both of which are made of metal or synthetic resin and have a C-shaped cross section. The length is predetermined.

Both members 1 and 2 have a large number of engagement holes 1a and 2a formed at regular intervals in the longitudinal direction of the members, for example, elongated engagement holes 1a and 2a as shown in the figure. Each side engagement hole 1a has a cut groove 1 on its longitudinal hole edge.
A plurality of b are formed at a fixed pitch.

One end of the other member 2 is brought into contact with the side surface of one member 1, and fixed to the abutting portion of both members via a joining metal fitting. The parts are held together to form a single piece.

That is, as shown in FIG. 3, one metal fitting piece 3 of the joining metal fitting is made of a single band-shaped plate and one end thereof is bent at a substantially right angle to form the member 1.
The engaging pieces 3a are arranged in a row so as to be in contact with the outer surface of the member 2, and the engaging pieces 3b and 30 are vertically opposed to each other on the upper and lower edges of the other end edge, and the engaging pieces 3a are arranged so as to hold the member 2. The member 1 is bent at a substantially right angle in the same direction as the engaging piece 3a, and the member 1 is held and supported between the inner surface of the engaging piece 3a and one side edge 3d of the engaging pieces 3b and 3c. Forming and upper and lower engaging pieces 3
The body of the metal fitting piece between bt3c has a female thread.

The other metal fitting piece 4 is formed by bending a band-shaped plate as shown in FIG. inner groove 1c
An insertion clamping piece 4a that is inserted into the interior and cooperates with the opposing metal fitting piece 3 to clamp the flat side surface portion 1d of the member 1.
An inner piece 4c is formed by bending one end of the insertion and clamping piece 4a at a substantially right angle so as to extend along the inner groove end surface 1e of the member 1, and one end of this inner piece 4c is bent parallel to the insertion and clamping piece 4a. The outer cover piece 4d is bent to form an outer cover piece 4d, and one end of this outer cover piece is further bent to form an outer piece 4e facing the inner piece.
Further bend one end of e so that it is parallel to the outer covering piece, and form the engaging piece 4f.
The U-shaped end 1A of the member 1 is inserted into the groove 4h formed in the inner piece, the outer covering piece, and the outer piece.

In addition, tongue pieces 4b are formed at both upper and lower ends of the insertion clamping piece 4a by vertically opposing each other and are bent in the opposite direction to the inner piece, the outer covering piece, and the outer piece. It is made to fit into the cut groove 1b formed on the edge of the matching hole.

Therefore, the pitch between the upper and lower tongue pieces 4b, 4b is shaped to match the pitch of the cut grooves 1b, 1b of the engagement holes provided adjacent to each other in the longitudinal direction of the member 1, so that The tongue piece is fitted into one of the provided grooves to provide firm support and is adjustable by the pitch of the grooves.

In addition, a screw hole 4g is bored in the engaging piece 4f, and both metal fitting pieces 3 and 4
When overlapping the screw holes 4g and 3e, screw the screw 5 into the screw holes 4g and 3e, and as shown in FIG. It is something to do.

According to the present invention, the joining between the two orthogonal members is achieved by holding the two members together with a metal fitting piece 3 that runs along the outer surfaces of both members and a metal fitting piece that runs along the inner surfaces of both members. The two members are engaged by tightening, and the tongue piece of the metal fitting piece is reselectively fitted into the cut groove provided on the edge of the engagement hole drilled in one member, so that the joint between the two members can be firmly established. Moreover, it has the advantage of being easy to work with since it can be done with a single screw.

Claims (1)

[Scope of utility model registration request] The end of one member is brought into contact with the side surface of the other member, and a metal fitting piece that is brought into contact with and held by the outer surface of the member at the joint of both members and a metal fitting piece that is inserted inside this member are connected with one screw. A joining fitting between members that is screwed together so that both members are held between the two fitting pieces.
