Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for connecting extruded sections in a crosswise state, which are used for door frames and other frameworks of storage furniture.

Storage furniture has double doors on the front, but the framework of these doors is made of extruded aluminum sections combined into a rectangular shape.
Both profiles form a corner at the joining position.

First, we will outline the conventional corner joint structure and clarify its problems.

The conventional general corner joining device 10 has a first
As shown in FIGS. 3 to 3, a notch 12 is formed at the end of the hollow profile 11, and the other profile 13 is abutted to this part, and two inserts formed on the sides of the profile 11 are formed. The two sections 11 and 13 are connected by inserting a mounting screw 16 through the holes 14 and 15 and screwing the threaded portion into the tapping hole 17 of the other section 13. A plastic cover 18 is fitted onto the end face of the section 13, and a plastic cap 19 is fitted into the insertion hole 14.

When the above-mentioned combined shapes 11 and 13 are used as a stile assembly for a single door, etc., the horizontal shape 1
When a load is applied to 3, as shown in FIGS. 2 and 3, the abutting part of the section 11, especially the upper mounting screw 16, deforms into an arc shape, causing the horizontal section 13 to tilt. Become. For this reason, a reinforcing plate or the like is required at the mounting screw 16 portion, that is, on the back side of the mounting surface. In addition, since the end face of the profile 11, the insertion hole 14, etc. are exposed to the outside, a cover 1 is used to hide it.
8 and cap 19 are required.

An object of the present invention is to provide a joining device for shapes that is robust and can be joined without exposing the end faces of the shapes to the outside.

Based on the above-mentioned object, the present invention is a combination of two sections each having an end wall and a facing wall each having a rectangular cross section, and connecting the ends of the sections to form a corner section. The apparatus is such that, with the end facing walls of both sections facing each other, the facing wall of one section covers the open end portion of the other section, and the facing wall of the other section covering the open end portion of one of the sections, interposing a spacing wall between the facing walls, and connecting the sections to each other; A second facing wall is provided which is continuous and flush with the timber facing wall.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

Shapes 21 and 22 forming the corner portion of the present invention
As shown in FIGS. 4 to 7, the shapes 21 and 22 are extrusion-molded with the same cross-sectional shape.
is provided with prospective walls 23, 24, first facing walls 25, 28, and second facing walls 26, 27, respectively, and a first spacing wall 39, 40 is provided at the center of the lower surface of the prospective walls 23, 24 in the prospective direction. Reinforcement plates 35, 3 provided with second spacing walls 37, 38 which are vertically installed and face the spacing walls 39, 40 at a certain distance.
6 are provided protruding from the inner surfaces of the first facing walls 25, 26, and the first spacing walls 39, 40 and the second
The spacing walls 37, 38 are the two facing walls 25, 28,
26 and 27, and the sides A and B facing the respective second facing walls 26 and 27 are facing walls 2.
3 and 24, it is located exactly in the center with respect to the expected direction.

The second facing wall 2 of both sections 21 and 22 like this
6, 27, shape fitting parts 29, 3 are formed by notches.
0, and in the facing walls 23, 24 which are in a protruding state due to the above-mentioned notch, the part closer to the second facing wall than the spacing retaining walls 39, 40 is provided with the end face covering part of the profile. Let's say d.

Then, the ends of both the sections 21 and 22 are brought into a perpendicular state at the section fitting portions 29 and 30, and the respective first interval retaining walls 39 and 40 and the second interval retaining wall 3
7 and 38 are brought into contact with each other in a facing manner, and each end face is brought into contact with the end face covering parts C and D of the other, and then the screw inserted through the first facing wall 28 of the shape member 22 is inserted into the shape member. 21 first and second spacing walls 39,
By screwing into 37, both sections 21 and 22 are connected together.

In addition, when making the notch in the profile 22, the end face of the profile wall 23 of the profile 21 can be covered with the protruding end portion 24 of the profile wall 23. The ends of the first facing wall 28 and the first and second spacing walls 40, 38 are cut by an amount corresponding to the wall thickness.

Also, the first facing wall 28 has mounting screws 33 and 34.
Screw insertion holes 45, 46 with a diameter slightly larger than the head of the
are provided, and the first and second spacing walls 3
Mounting screws 33 and 34 corresponding to 8 and 40
Mounting holes 47 and 48 are drilled through which only the threaded portions of the screws can pass. In addition, the first and second spacing walls 3 of the profile 21
7 and 39 have screw holes 49 and 50 formed at positions corresponding to the mounting holes 47 and 48, respectively.

Next, FIGS. 8 to 10 show other embodiments of the present invention. One of the sections 21 has the same cross-sectional shape as that of the above embodiment, but the other section 22a
has a cross-sectional shape in which a spacing retaining wall 40 with a narrow width is connected to the first facing wall 28 by an auxiliary plate 51. Correspondingly, two screw insertion holes 45, 46 and attachment holes 47, 48 are formed in the common spacing wall 40.

Further, in the present invention, a shape member having a cross-sectional shape as shown in FIGS. 11 and 12 can be used.

The profile 22b shown in FIG.
4, facing wall 26, spacing wall 40 and auxiliary board 5
1, and the spacing wall 40 is located at the center of the facing wall 24 in the viewing direction.

If this profile 22b is used, the part that is cut out when connecting it to another profile is a part of the short support wall 28a hanging from the tip of the prospective wall 24, resulting in material loss. In addition to being small, the rigidity of the shape member 22b is strong due to the presence of the hollow portion, and the strength of the corner portion after connection is also sufficient.

The profile 22c shown in FIG.
The spacing retaining wall 4 is connected via an auxiliary plate 51 protruding from
0, and approximately T on the spacing wall 40.
It is made up of a series of letter-shaped protruding walls 28b, and the spacing wall 40 is of course located at the center of the prospecting wall 24 in the perspective direction. When using such a shape member 22c, the end portions of the projecting wall 28b and the short support wall 28a vertically disposed at the tip of the prospective wall 24 are cut off.

The other profile connected to these profiles 22b, 22c can be the same as the previously described profiles 22, 22a.

In each of the above-mentioned embodiments, the two sections form a right-angled corner, but the intersection angle can be set arbitrarily. Correspondingly, the cutting angles of the profile fitting portions 29 and 30 will change.

As described above, in the present invention, the cut end surfaces of both sections can be cut off by a simple process of leaving the facing wall and expected wall on one side of the end of the section and cutting off the facing wall on the other side. It can be covered with the side profile, so
The holes unique to the end faces of the profile are not exposed to the outside, and there is no need for conventional caps for covering the end faces, and the associated complicated installation work can be omitted, reducing costs. The reduction can be measured. In addition, due to the presence of the facing wall on one side of both sections, a continuous facing face with a beautiful appearance and the same plane is formed. Furthermore, it has the effect of being able to obtain a robust joint structure through the synergistic effect of the interposition of the spacing wall between the facing walls of the two sections facing each other and the intersecting fitting of the end faces. It is something.
