Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the structure of frame materials used for vertical bars, diagonal bars, etc. in gates, fences, etc.

(Prior art) As a conventional frame material of this kind, for example,
There is one shown in Publication No. 83588. The frame material of this known example is bent by forming a notch defined by a substantially arc-shaped roundness regulating surface and a straight bending regulating surface at the planned corner portion.

(Problems to be Solved by the Invention) However, in the frame material of the above-mentioned known example, it is necessary to form the notch in a substantially arc shape, which makes machining difficult. Furthermore, since the end surfaces of the notches are simply brought into contact with each other, there is a problem in that the strength of the frame material is low.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned points, and is designed so that a part or all of the lip portions of a profile having an opening formed by a pair of opposing lip portions remain. A corner member is formed by processing a notch to form a curved part, and after bending the curved part inside the curved part to a desired angle, the corner member consists of a base part that comes into contact with the end surface of the notch and a mounting part having an engagement groove. is press-fitted into the opening of the curved portion or the lip portion near the curved portion, thereby fitting the curved portion or the lip portion or both into the engagement groove. It is something to do.

(Function) In the present invention, the mounting portion of the corner member is press-fitted into the opening of the mold material, and the curved portion of the mold material, the lip portion near the curved portion, or both are engaged with the engagement groove. The strength of the material is extremely high, and
It has the effect that it is only necessary to process the notch into a straight line.

(Example) The embodiments shown in the drawings will be described below.

In the embodiment shown in the drawings, the present invention is applied to a vertically elongated and approximately square-shaped vertical frame member 1 forming a telescoping gate X shown in FIG.
An example is shown below.

Aluminum mold material 2 forming vertical frame material 1
is a pair of L-shaped lip portions 21, 21 facing each other.
The lip portion 21,
21 has an opening 22 in the longitudinal direction. As will be described later, the corner members 3 are press-fitted and fixed at two desired locations on the profile 2 to form the vertical frame 1 having a horizontal portion 2a and a pair of left and right vertical portions 2b, 2b. Since the corner portions 1a and 1a have the same structure, only one will be described representatively.

In the first embodiment shown in FIGS. 1 to 6, a notch 4 of an appropriate width is formed at a desired position of the mold material 2 so that a portion of the lip portions 21, 21 remains, and the curved portion 5 is , 5 are bent into a circular arc shape with the bent portions 5, 5 inside to form a horizontal portion 2a and a vertical portion 2b.
It is as if the angle is a right angle. On the other hand, the corner member 3 can be integrally molded from synthetic resin, and comes into contact with the end faces 41, 41 of the notch 4 (i.e., the end faces of the horizontal part 2a and the vertical part 2b), respectively, and has a rounded outer shape. The curved base 31, the above-mentioned curved portions 5, 5 and the lip portions 21a, 21a, 2 near the curved portions 5, 5 in the horizontal portion 2a and vertical portion 2b.
1a and 21a, and a fitting portion 32 that fits closely into the corner end portions of the horizontal portion 2a and the vertical portion 2b.
b, 32b. Although the fitting portions 32b, 32b are not necessarily necessary, their presence increases the contact area between the shape material 2 and the corner member 3, and has the effect that a more robust vertical frame material 1 can be obtained. Further, the tip of the mounting portion 32 of this corner member 3 is formed into a tapered shape so that it is guided into the opening 23 when press-fitting.

Attachment portion 3 of corner member 3 formed in this way
2 is the curved portions 5, 5 of the mold material 2 and the lip portions 21 near the curved portions 5, 5 in the horizontal portion 2a and vertical portion 2b.
a, 21a, 21a, 21a, the opening 22 expands slightly due to the elastic deformation of the mold material 2, and the curved portions 5, 5 and the lip portions 21a, 21
a, 21a, 21a are fitted into the engagement groove 32a, and the assembly is completed.

In the connection between the shape material 2 and the corner member 3 in the present invention, it is only the engagement groove 32a of the corner member 3 and the curved portions 5, 5 of the shape material or the lip near the curved portions 5, 5 that engage with each other. Parts 21a, 21
Although only a, 21a, and 21a may be used, in this embodiment, both are engaged with each other to make it more robust.

In the second embodiment shown in FIGS. 7 to 9, a pair of L-shaped lip portions 2 facing each other are provided as in the first embodiment.
1, 21 is used, and the curved portions 5, 5 are formed by cutting a notch 4 deep enough to leave all the lip portions 21, 21 remaining. Therefore, the engagement groove 3 of the corner member 3
2a is different from the first embodiment, as shown in FIG. have the same width. Others are first
Since this is the same as the embodiment, the explanation will be omitted.

In addition, in the first and second embodiments, a molded material having an L-shaped lip portion and having a generally square cross section was used, but it is possible to use a molding material having a roughly square cross section instead of this. Needless to say. That is, the shape material is not limited to the present embodiment as long as it has a lip portion and thus an opening.

Further, although the corner member in this embodiment has an arc-shaped outer shape, it is also possible to have an angular shape or an appropriately decorated one.

Further, in this embodiment, the corner portions were formed so that the horizontal portion and the vertical portion formed an angle of about 90°, but it goes without saying that the opening angle can be freely set in the present invention.

Further, in the above embodiment, the corner portions were provided at two locations on the top of the frame material, but the corner portions may be provided at two locations at the bottom or at two locations each on the top and bottom. Furthermore, when implementing the present invention, the specific shape, structure, or material of each member can be changed in various ways, such as the fact that the present invention can be implemented even when there is only one corner portion, as long as it does not contradict the gist of the invention. Of course.

(Effects of the invention) The present invention is as described above, and has a structure in which the curved part or the lip part near the curved part, or both, are engaged with the engagement groove of the corner member by utilizing the elasticity of the shaped material. The effect is that a frame material with extremely high strength can be obtained by a very simple operation.

In addition, the notch for forming the curved portion may be processed into a straight line, and there is an effect that workability is improved.

Furthermore, since the outer shape of the corner member can be changed as appropriate, it also has the effect of contributing to an improvement in appearance by using one with a desired decoration.
