Description

[Detailed Description of the Invention] The present invention relates to an improvement of a shape connecting device used for joining corner portions of aluminum alloy extruded shapes.

A die-cast product generally formed into a block shape as a conventional shape connecting device used to connect the corners of extruded aluminum alloy shapes.
Synthetic resin molded products are available.

However, even if die-cast products and resin molded products are painted in a color similar to that of the aluminum molding material, which is the main component, there will be significant differences in material feel, color tone, gloss, etc., resulting in an unnatural appearance even after assembly. Not only does it look inferior and reduce the product value, but there are certain restrictions on reducing the wall thickness due to strength and molding reasons, which limits the degree of freedom in design. Compared to aluminum shapes, which are the main components, these products and painted products have drawbacks such as being inferior in various aspects such as strength and durability, and being susceptible to deterioration over time.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and is provided with a corner joint member 1 which is inserted and fixed into the abutting corner portions of the main members 2, 2 made of extruded aluminum alloy members, respectively. A cover body 5 made of the same material and subjected to the same surface treatment as the main members 2, 2 is integrally fixed to the outer corner of the joint member 1, so that when the main members 2, 2 are butt-connected, The entire corner joint member 1 is covered by the main members 2, 2 and the cover body 5, and the outer corner of the abutting corner of the main members 2, 2 is covered by the cover body 5. The gist of this is that

To explain the configuration of the present invention with reference to an embodiment shown in the drawings, 1 is a corner joint member;
This joint member 1 has insertion portions 1 inserted into hollow portions 3 of the main members 2, 2, respectively, at the butt corner portions of the main members 2, 2 made of extruded aluminum alloy members.
a, 1b are inserted, and the main members 2,
It connects and fixes two comrades. In the illustrated example, the joint member 1 is made of an extruded aluminum alloy material, but it is not limited to the extruded aluminum material, but may be made of other materials. Reference numeral 5 denotes a cover body made of the same material as the main members 2, 2, and subjected to the same surface treatment.This cover body 5 has projecting portions 5a on both sides.
It consists of a generally umbrella-shaped head 5' provided with a diameter 5a and a leg 5'' having a Y-shaped cross section, and the leg 5'' is inserted into the grooves 6, 6 provided in the joint member 1 and crimped, etc. The cover body 5 is integrally fixed to a predetermined position of the joint member 1.

In the above-described embodiment, the cover body 5 is formed separately from the joint member 1, but the cover body 5 and the joint member 1 may be formed integrally in advance.

In the figure, 7 is a tapping hole, and 8 is a screw hole.

In the above configuration, to connect the main members 2, 2, insert the insertion parts 1a, 1b of the joint member 1 into the hollow parts 3 of the main members 2, 2, respectively, and the main members 2, 2 can be connected as shown in FIG. The members 2, 2 are positioned such that their outer end surfaces 2' are in contact with the back surfaces of the projecting portions 5a, 5a provided on the head 5' of the cover body 5. Then, insert screws 4, 4,... into screw hole 8 and tapping hole 7.
It is screwed into and fixed in place.

As described above, the present invention provides a corner joint member 1 that is inserted and fixed into the abutting corner portions of the main members 2 and 2 made of extruded aluminum alloy members, respectively, and the outer corner portion of the corner joint member 1 is A cover body 5 made of the same material and subjected to the same surface treatment as the main members 2, 2 is integrally fixed to the main members 2, 2, and when the main members 2, 2 are butt-connected, the entire corner joint member 1 is fixed to the main members 2, 2. 2 and the cover body 5, and the outer corner portions of the abutting corners of the main members 2, 2 are covered by the cover body 5. Therefore, the main member is made of an extruded aluminum alloy material. The outer corner of the abutting corner part is covered and protected by the cover body, and the entire corner joint member is covered by the main member and the cover body without being exposed to the outside. is integrally inserted and fixed into the hollow part of the main part, which not only further increases the connection strength of the main part, but also prevents defects such as slight machining misalignment at the corner joint of the shape material, which is the most important point in terms of design. Even if there is a problem, it can be covered with the cover body after assembly, and the corner joint member can be completely hidden inside the main member and the cover body, and the cover body exposed on the outside can be hidden inside the main member. Since it is made of the same material and has the same surface treatment as the extruded aluminum alloy mold material of This makes it possible to prevent discomfort from occurring due to changes over time, and to improve workability and assemblability. In particular, this invention is suitable for use with die-cast products and synthetic resin molded products as corner joint members. It is extremely useful as an equal-shaped material connection device that can completely eliminate the discomfort between the main component made of extruded aluminum alloy material and the corner joint component, while increasing the connection strength even when using aluminum alloy extruded material. It has many practical effects.

[Brief explanation of drawings]

FIG. 1 is an overall perspective view of the present invention, and FIG. 2 is a sectional view of the corner joint after connecting the main members. In the figure, 1 is a corner joint member, 2 and 2 are main members, and 5 is a cover body.
