Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly structure of a handrail, a fence, a lattice or the like made of an aluminum material.

[0002]

2. Description of the Related Art As an assembling structure of a joining member of a horizontal member and a vertical member such as a handrail and a fence made of aluminum, an actual construction is adopted.
There are technologies such as No. 6-70033, No. 56-71850 and No. 162520. These techniques will be described with reference to FIGS.

In the drawing, 1 horizontal member 2 is a vertical member having a quadrangular cross section, and a hole 3 having a size such that an end portion of the vertical member 2 is fitted to a joint portion of the horizontal member 1 with the vertical member 2. Is open. Therefore, a locking tongue piece 4 is formed to face the end of the vertical member 2,
In order to form each locking tongue piece 4, an abutment surface 5 is formed at a position where the opposite piece at a position 90 degrees adjacent to the locking tongue piece 4 is cut off.

The size of the hole 3 of the horizontal member 1 is such that the locking tongue piece 4 of the vertical member 2 just fits and the contact surface 5 contacts the periphery of the hole 3. According to the above-mentioned structure, the locking tongue piece 4 of the vertical member 2 fitted in the hole 3 of the horizontal member 1 is bent 90 degrees along the horizontal member 1 so that the horizontal member 1 is bent. 4 and the contact surface 5 that is in contact with the cross member 1 on the opposite side with the cross member 1 sandwiched between them, and a fixed state is obtained to be integrated.

[0005]

According to the conventional assembly structure of the joint portion as described above, an integrated structure of a horizontal member and a vertical member can be obtained without requiring welding work or screwing. The locking tongue, which is the tightening part, and the contact surface are 9
There is a problem that the fixed state is weak and a stable joint state cannot be obtained because the 0 degree position is not the same place and the fixing place is two places facing each other. There is a problem of being unstable.

[0006]

SUMMARY OF THE INVENTION Therefore, according to the present invention, an engaging hole is provided in a transverse member, an engaging tongue piece is formed in a protruding manner in the engaging hole, and the engaging tongue piece is extended to an end of a vertical member. Formed as a contact surface between the bases of the locking tongues, and the locking tongue of the vertical member is fitted to a portion of the locking hole of the horizontal member where there is no locking tongue and the contact surface is a horizontal member. Abutting against the surface, bend the locking tongue of the vertical member along the horizontal member, and further bend the locking tongue of the horizontal member along the vertical member so that the horizontal and vertical members It is characterized in that the materials are sandwiched and joined together.

According to the above construction, the vertical members are sandwiched by the locking tongues formed in the locking holes of the horizontal members, the horizontal members are sandwiched by the vertical locking member tongues, and both locking tongues are Since they are sandwiched from opposite directions, a strong and stable joined state can be obtained.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same parts as those in the above-mentioned conventional technique will be described using the same reference numerals. FIG.
2 is a cross-sectional view showing a bonded state, FIG. 2 is a plan view of a main part of a horizontal member, and in the drawing, 1 is a horizontal member and 2 is a vertical member having a rectangular cross section. Locking tongues 4 are formed at the ends of the vertical members 2 so as to face each other, and in order to form the locking tongues 4, the locking tongues 4 are cut off at the opposite sides 90 degrees adjacent to each other. A contact surface 5 is formed at the location.

A locking hole 6 having a size for receiving the locking tongue 4 of the vertical member 2 is provided at a portion where the horizontal member 1 is joined to the vertical member 2, and the locking hole 6 has two opposing sides. Form the locking tongue 7. This locking hole 6 will be further described. The locking tongue piece 4 of the vertical member 2
And a vertical member 2 having an abutment surface 5 sandwiched between the locking tongues 4 thereof.
The engaging holes 6 are formed in such a size that the engaging tongues 4 facing each other can be just inserted. That is, when both of the locking tongues 4 of the vertical member 2 that are opposed to each other are inserted into the locking holes 6, the contact surface 5 contacts the periphery of the locking holes 6 and stops, and only the locking tongues 4 are locked. 6, the locking tongue 7 of the locking hole 6 is located at a position 90 degrees adjacent to both the locking tongues 4, that is, at the side where the contact surface 5 contacts.

The base of the locking tongue 7 of the locking hole 6 preferably coincides with the inner end of the contact surface 5 of the vertical member 2, and in this case, the width of the locking tongue 4 is The width of the vertical member 2 is just enough to fit into the locking hole 6, and the width of the vertical member 2 is reduced. When the position of the inner end of the contact surface 5 deviates from the above position, the inner end of the contact surface 5 is located outside the periphery of the locking hole 6 when the locking tongue 7 described later is bent. It is not preferable because it creates a gap in the locking hole 6, and it is better to position it so as to enter the inside of the locking hole 6.

In this way, the locking tongues 5 of the vertical members 2 are fitted into the locking holes 6 of the horizontal members 1, the locking tongues 4 are bent along the horizontal members 1, and the locking tongues of the horizontal members 1 are further bent. Each piece 7 is a vertical member 2
By bending along the inner surface of the locking member 5, the locking tongue 4 clamps the cross member 1 together with the contact of the contact surface 5 to the vicinity of the locking hole 6, and then the locking tongue 4 is positioned 90 degrees next to it. 7, the vertical member 2 is sandwiched from the opposite side, whereby the joined state of the horizontal member 1 and the vertical member 2 can be obtained.

In the above description, the vertical member 2 has a quadrangular cross-sectional shape, but the vertical member 2 may have any cross-sectional shape, such as a circle or the like as shown in the explanatory view of FIG. The shape may be an ellipse or a polygonal shape (not shown). In any shape, a protruding contact surface 5 that abuts a part of the periphery of the locking hole 6 of the cross member 1 The locking tongues 4 facing each other are formed, and the locking tongues 4 are the cross members 1.
It suffices that the contact surface 5 comes into contact with a part of the periphery of the locking hole 6 after entering the locking hole 6 and the locking tongue 7 provided in the locking hole 6 is bent into the vertical member.

[0013]

According to the present invention described in detail above, an engaging hole is provided in a transverse member, and an engaging tongue piece is formed to project in the engaging hole, and the engaging tongue piece is extended to an end portion of a vertical member. The base of the locking tongue is used as an abutting surface, and the locking tongue of the vertical member is fitted to a portion of the locking hole of the horizontal member where the locking tongue does not exist and the contact surface is made horizontal. Abutting against the material surface, the vertical tongues are bent along the horizontal members, and the horizontal tongues are bent along the vertical members so that the horizontal tongues Since the vertical members are sandwiched and joined to each other, the horizontal members and the vertical members are sandwiched by the locking tongues. There is an effect that an extremely strong and stable joined state can be obtained only by the step of bending.
