Description

[Detailed Description of the Invention] The present invention relates to a metal fitting that firmly and adjustablely joins two orthogonal shapes.

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

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

A large number of engagement holes 1a and 2a, for example, elongated engagement holes 1a and 2a as shown in the figure, are bored in the flat sides of both the shapes 1 and 2 at regular intervals in the longitudinal direction of the shapes. ,
A plurality of grooves 1b and 2b are formed on the hole edge in the longitudinal direction of the hole 2a at a regular pitch.

With the two molded materials 1 and 2 formed in this way, one end of the other molded material 2 is brought into contact with the side surface of one of the molded materials 1, and the two molded materials are fixed to the abutting part via a joining metal fitting. The metal fittings are held together by two metal fitting pieces 3 and 4, respectively, and the tongue pieces are locked in the cut grooves to firmly unite them.

That is, as shown in FIG. 3, one metal 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 shape material 1.
The engaging pieces 3a are arranged in a row so as to be in contact with the outer surface of the shape material 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 profile 2. 3a, and is formed by bending at a substantially right angle in the same direction as the engaging piece 3a, and the shape material 1 is held and supported between the inner surface of the engaging piece 3a and one side edge 3d of the engaging piece 3be3c. The main body of the metal fitting piece between the upper and lower engaging pieces 3b and 3c is provided with a screw hole 3e with an internal thread, and the other metal fitting piece 4 is shown in FIG. One end of the band-shaped plate is bent and formed as shown in FIG. Forming an insertion clamping piece 4a for clamping,
An inner piece 4c is formed by bending one end of this insertion clamping piece 4a at a substantially right angle so as to follow the inner groove end surface 1e of the mold material 1, and one end of this inner piece 4c is bent parallel to the insertion clamping piece 4a. One end of the outer cover piece 4d is further bent to form an outer piece 4e facing the inner piece, and one end of this outer cover piece 4e is further bent parallel to the outer cover piece to form an engaging piece 4f. At the same time, the U-shaped end portion IA of the profile 1 is inserted into the groove 4h formed by the inner piece, the outer covering piece, and the outer piece.

In addition, tongue pieces 4b are vertically opposed to each other at both upper and lower ends of the insertion clamping piece 4a, and bent in the opposite direction to the inner piece, outer cover piece, and outer piece to form a shape, and on the outer edge of the engaging piece 4f. tongue piece 41
is provided in the same manner, and this tongue piece 4b is placed in the cut groove 1b formed on the edge of any one engagement hole of the profile 1, and the tongue piece 4
1 are fitted into the notches i2b of the engagement holes of the mold material 2, respectively.

Therefore, the pitch between the upper and lower tongue pieces 4b, 4b is the cutout i1b, lb of the engagement hole 1a provided adjacently in the longitudinal direction of the mold material 1.
The tongue piece is shaped to match the pitch of the grooves, and the tongue piece is fitted into one of the grooves provided in the same engagement hole to firmly support it, and the pitch of the grooves can be adjusted.

In addition, a screw hole 4g is drilled in the engaging piece 4f so that when the two metal fitting pieces 3 and 4 are stacked, the screw holes 4g and 3e overlap each other, and the screw 5 is screwed into this, as shown in FIG. The shapes 1 and 2 are clamped and joined between the metal fitting pieces 3 and 4.

According to the present invention, the joining between the two orthogonal shapes is achieved by holding the two shapes together using a metal fitting piece 3 that runs along the outer surface of both shapes and a metal piece 4 that runs along the inside surface of both shapes. The tongues 4b and 41 of the metal fitting piece 4 are selectively fitted into the grooves provided on the edges of the engagement holes drilled in both molds by tightening the two molds. It has the advantage that the connection between the parts can be made firmly, and it can be done with a single screw, so the work is simple.
