Description

[Detailed Description of the Invention] This invention relates to a connection structure for shapes that can be used as vertical members for partitions in buildings, vertical members for windows, and the like.

As is well known, there are various structures of building materials, such as a material with a pocket portion on one side for fitting a panel such as glass, and a material with the pocket portions on two sides.

However, a profile having a pocket cannot be used for a profile that does not require a pocket.

Furthermore, a profile having pockets on two or three sides cannot be used for a profile requiring pockets on only one side.

Therefore, in the present invention, the unnecessary pocket portions of the first mold material having two or more pocket portions are connected so as to be closed by the second mold material. The purpose of the present invention is to provide a connection structure for shapes that prevents the shapes from coming off or loosening easily.

The present invention will be described above with reference to the illustrated embodiment. The first mold member 1 is an extrusion molded material made of aluminum or other metal, and a pocket portion 3 opening on the surface is formed along the longitudinal direction on one side 2.

The pocket portion 3 is located in the hollow interior of the first mold member 1, has a U-shaped cross section, and forms side-stopping cavities 4, 4 laterally from the pocket portion 3 on the left and right sides of the opening end.

Each fastening cavity 4 has an opening base end 5 that is narrower than the inner width due to protrusions 6, 6 which are provided oppositely.

The second mold material 7 that connects the pocket portion 3 of the first mold material 1 so as to close it has a long flat plate shape. Extend along the direction.

Each locking part 8 has a base end 9 extending from the surface of the second mold member 7, a flat part 10 that faces sideways from the tip of the base end 9, and a flat part 10 that slopes toward each other from the front end of the flat part 10. Slope part 1
1, and has U-shaped groove portions 12 on the left and right sides that are surrounded by the side edge back surface of the second mold member 7, the outer surface of the base end portion 9, and the flat portion 10 and open outward.

The above-mentioned second mold material 7 is extruded from metal such as aluminum in the same manner as the first mold material 1, and claw portions 13 are formed at appropriate intervals on each of the locking portions 8 after molding.

The claw portion 13 is formed by cutting and raising a portion of the flat portion 10 and a portion of the inclined portion 11 excluding the tip, and protrudes outward, and can be formed in a post-processing process such as by pressing to provide elasticity. However, it may be provided on both locking portions or only on one of the locking portions.

The base end portions 9, 9 interval 1 of the left and right locking portions 8, 8 described above is as follows:
It is shorter than the opening width of the pocket portion 3 of the first mold member 1 described above.

However, the distance 1' between the tips of the flat parts 10 and 10 of the left and right locking parts 8, 8 is longer than the width of the opening.

To connect the pocket portion 3 of the first mold material 1 so as to close it with the second mold material 7, the second mold material 7 is applied to the opening of the pocket portion 3, and both locking portions 8 are attached to the left and right side edges of the pocket portion. ,8
, and tap or strongly press the second mold member 7 from the surface to fit the left and right side edges 3 ′, 3 ′ of the pocket portion 3 into each groove portion 12 and align the flat portion 10 of each locking portion 8 with the inclined surface portion 10 . A part of the portion 11 is fitted into the fixing hollow portion 4 to be connected.

However, after fitting one side edge 3' of the pocket part 3 into the groove part 12 of one of the locking parts 8, the second mold member 7 is struck or strongly pressed, and the pocket part 3 is fitted into the groove part 12 of the other locking part 8. The connection may be made by fitting the other side edge 3' of the two sides.

In any of the above cases, when fitting, the claw part 13 and the locking part 8
slides on the side edges 3' due to elasticity, and after fitting, each side edge 3' of the pocket part 3 is firmly fitted into the groove part 12 of each locking part 8, and each flat part 10 slides on the inside of the side edge 3'. to lock.

Further, since each claw portion 13 comes into contact with the opening base end portion 5 of the fastening cavity 4, the connection between the first mold member 1 and the second mold member 7 is strengthened, and loosening and rattling is prevented.

Therefore, the opening end of the pocket portion of the first mold member 1 is connected to the second mold member 7.
This will cause a strong blockage.

In the embodiment described above, the pocket portion 3 is provided on one surface of the first mold material 1, and the pocket portion 3 is connected to the second mold material 7 so as to be closed.

In the embodiment shown in FIG. 3, pocket parts 3 are provided on two opposing sides of the first mold material 1, and one pocket part 3 is connected to the second mold material 7 so as to be closed by the other pocket part 3. The figure shows the case where panel a is fitted to.

It should be noted that the symbols not explained in FIG. 3 have the same structure as the same symbols in the embodiment described above, so the explanation will be omitted.

In this way, according to the present invention, the pocket portion of the first profile member is
Since the connection can be made extremely easily using the molding material, even if the first molding material has the same configuration, it can be used in a wide range of applications and has high versatility.

In addition, the claw part of the locking part provided on the second mold material not only fits into the fastening cavity at the opening end of the pocket to prevent the second mold material from loosening or coming off, but also prevents the second mold material from loosening or coming off. Even if the widths are slightly different, the second mold member can be connected to reliably close the open end of the pocket portion.

Therefore, even if the opening ends of the pockets formed on the surface of the first mold material are slightly different, the second mold material can be reliably connected without coming off or loosening.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, in which Fig. 1 is a cross-sectional view of the first mold material and the second mold material in a separated state, Fig. 2 is a perspective view of the second mold material, and Fig. 3 is a two-sided view.
