Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to construction materials used for frames of fences, handrails, bay windows, etc., gate posts forming the mouth shape of gates, vertical bars, diagonal posts, etc. of gate bodies in telescoping door devices. Regarding frame materials.

The ends of a pair of opposing frame elements, or the ends of a pair of frame elements and another frame element disposed between them, are connected through a corner joint member different from the frame elements. Architectural frame materials that are formed by connecting two parts have the disadvantage of being expensive due to the large number of parts.

Instead of such a construction frame material, in order to avoid using a corner joint member, for example, a right-angled V-shaped groove is notched in the planned corner part, and the planned corner part is bent so that this V-shaped groove disappears. Architectural frame materials having corner portions are known. However, in the case of this frame material, the outer surface of the corner portion is, for example, substantially right-angled and cannot be rounded.

For this reason, when used for the frame of a fence or the crosspiece of a telescopic door device, etc., the angular appearance is bad, and if the frame material has been previously subjected to surface treatment such as painting, the corner There are defects such as cracks and whitening in the surface treatment layer.

On the other hand, the present applicant has proposed an architectural frame material whose corner portions can be relatively thickly rounded. This frame material is shown in FIGS. 1 and 2. In the figure, 1 is the frame main body having notch grooves 2t at the planned corners, 3 is a bending part, 4 is a main part 4b having an arc-shaped bending regulating surface 4a, an insertion part 4c and an elastically deformable engagement part. This is a bending regulating body made of a molded product with a protrusion of 4d. After inserting the insertion part 4c into the inner space 1a of the frame main body 1, the corner part of this frame material is bent by bending the frame main body 1 in the direction of arrow 5 in FIG. It is formed by aligning the regulating surface 4a and elastically deforming the engaging portion 4d to pass it between the engaging flanges lb and Jb of the frame main body 1 and engaging with the inner surfaces of these flanges Ib and 1b. be done. Although the corner portions of such construction frame materials are formed with relatively large roundness on the outer surface, there is a problem that cost reduction cannot be achieved due to the necessity of bending regulating bodies.

The present invention was proposed based on the above circumstances, and
The purpose of this is to create a portion of the frame material that corresponds to the bending regulator, so that it looks good and prevents cracks and whitening from occurring at the corners even when surface treatment has been applied. To provide a frame material for construction, which has a simple structure and can significantly reduce costs.

The present invention will be described below with reference to an embodiment shown in FIGS. 3 to 7.

FIG. 3 shows a telescoping door device, which includes a gate post 11, a telescopic gate body 12, and a plurality of connectors 13, 13 such as hinges supporting one end of this body 12 to the gate post 11. It is formed by The gate main body 12 includes, for example, end vertical bars 14, 14, a plurality of vertical bars 15 as building frame materials according to this embodiment arranged between these, and these end vertical bars 14. and the vertical bars 15, and the vertical bars 15...
・Multiple oblique pillars 16 that connect each other so that they can approach and separate from each other.
It is formed from... In addition, Fig. 3 shows the diagonal pillars 16...mutual pivots, B represents the diagonal pillars 16...movable pivots that connect each other and slide up and down along each vertical axis)5J4, 15; C5σ is the diagonal column and each vertical beam 14.1
This is a fixed axis that connects the 5.

The vertical bars 15 are made of synthetic resin or metal such as aluminum alloy, stainless steel, steel plate, etc. In this embodiment, they are made of extruded aluminum alloy and have the cross-sectional structure shown in FIG. This shows the case where the ), and are formed as shown in FIGS. 4 to 7 VC, respectively. That is, the vertical beam 15 has a pair of opposing parts 5a h
J 5 a, and a part 15b that integrally connects the upper ends of these parts 15m and 15m, forming an L-shaped frame shape,
Its corner portions F, F have relatively large roundness on the outer surface. In the case of this embodiment, the frame shape of the vertical beam 15 is configured so that its shape is maintained by the above-mentioned fixed pivot C which is horizontally suspended at the end opposite to the portion 15b. and,
The corner part F is a notch 17 in advance at the planned corner part of the vertical beam 15.
It is provided by forming a notch 17 and bending the intended corner portion so that the notch 17 disappears. Needless to say, the planned corner portion is set between the portions 5-15a and 15b. The notch 17 is continuous with a curved portion 18 that is thinner than the other portions 15m and 15b connected to the planned corner portion, and from both ends of the curved portion 18, and faces the inner surface of the curved curved portion 18. At the same time, a pair of roundness regulating surfaces 19.19 are formed in a substantially arc shape that gradually separate from the curved portion 18, and each of the pair of roundness regulating surfaces is continuous from the tip thereof, and a predetermined opening angle θ is provided between them. It is formed by being separated by a pair of bending regulating surfaces 20°20.

In this embodiment, since the vertical bar 15 has a structure in which L-shaped flanges E and E are integrally provided at both ends of the web D, in order to make the bending portion 18 easier to bend, The case where the bending portion 18 is formed only by the web D is shown. but,
However, in the present invention, the seventh run E that defines the width of the vertical beam I5 is cut halfway, and the curved portion 18 is formed by the ledger portion consisting of the remaining cross fD and a part of the flange E. Good too. Further, in this embodiment, the opening angle θ is set to 90° so that the first law angle of the corner portion F is 90°, but in the present invention, the opening angle θ can be set arbitrarily. Of course, it can be set to Moreover, even when obtaining the same opening angle θ, the pair of protrusions facing each other formed by the roundness regulating surface 19 and the bending regulating surface 20 are not provided symmetrically as in this embodiment. There is no problem even if it is provided asymmetrically. Moreover, in this embodiment, the roundness regulating surface 19 is formed as an arcuate surface.
In the present invention, the roundness regulating surface 19 may be formed by a single slope, a continuous surface of a plurality of slopes slightly different in direction, a continuous surface of a slope and an arc surface, etc. Needless to say, it is included in the concept of an approximately arc shape. By bending the planned corner portion, each of the bending regulating surfaces 20 and 20 comes into contact with each other, and each of the roundness regulating surfaces 19 and 19 comes into contact with the inner surface of the curved portion 18,
A corner portion F is formed. Therefore, the bent portion 18 is bent along the pair of continuous bending regulating surfaces 20.20, and forms a relatively large roundness on the outer surface of the corner portion F.

Note that 21 in FIGS. 4 and 6 is a small gap formed at the corner F, and in this embodiment, in order to extend the life of the cutter used to form the notch 17, This was formed as a result of increasing the thickness of the . Further, reference numeral 22.22 in FIG. 5 is a hole for attaching the fixed pivot C.

In addition, although the above embodiment shows a case where rounded corners are provided at two locations on the upper part of the building frame side, the same corner sections may be provided at two locations at the lower part. The same corner portion may be provided at each location. Furthermore, it can be implemented even when there is only one corner portion. In addition, in carrying out the present invention, unless it is contrary to the spirit of the invention, 91 curved parts, roundness regulating surfaces,
The specific structure, shape, position, etc. of the bending regulating surface, notch, etc., the size of the opening angle, other materials, etc. are not limited to the one embodiment described above, and can be configured and implemented in various ways. Of course.

The present invention described above has the gist of the configuration described in the claims above. That is, in the present invention, a notch defined by a thin curved portion, a pair of roundness regulating surfaces, and a pair of bending regulating surfaces is formed by bending a pre-provided corner portion, thereby adjusting each bending regulation. This is an architectural frame material having a corner portion formed by bringing the surfaces into contact with each other and by bringing each roundness regulating surface into contact with the inner surface of the curved portion. Therefore, since the outer surface of the corner portion is rounded, it is possible to provide an architectural frame material with a good appearance due to this roundness.

Then, when forming the corner part, a pair of roundness regulating surfaces are
This prevents excessive force from being applied to the curved parts due to bending.
Even if the curved portion has been previously surface-treated with a paint film, resin coating, etc., it is possible to prevent cracks and whitening from occurring in the surface treatment layer of the curved portion as the curved portion is bent.

Furthermore, since the part for regulating the roundness of the curved part is formed from a part of the architectural frame material, a bending regulating body is not required compared to the above-mentioned architectural frame material proposed by the applicant. I don't.

Therefore, the structure is extremely simple, and the cost can be reduced by reducing the number of parts and the time and effort required to form the corner portions.
