Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to handrail supports installed on balconies, stair landings, etc., and is particularly applicable to handrails on both sides of the support that are not aligned in a straight line or at right angles. This invention relates to a strut structure that allows the strut installed at a curved part to correspond to the bending angle of a handrail.

[Conventional technology] For building balconies, stairs, stair landings, etc.
For safety, columns 2 are erected along the edge of the floor 1 and handrails 3 are erected, as shown in the elevation view in Figure 6a and the plan view in Figure 6b. Due to the design of objects, handrails are not necessarily in a straight line, and in many cases the direction of bending is not at right angles. Conventionally, in such a handrail body, ordinary posts 2 are erected in each direction on both sides of the bending point of the handrail 3, and only the cap 3A is extended to the bending part, and connected with a miter or the like. I was letting it happen.

In addition, for commonly adopted angles such as 120° and 135°, or for a large number of angles,
As shown in FIG. 7, a strut 2A dedicated to the bending portion is manufactured and prepared. The present applicant's earlier idea (Jetko Kosho 61-
No. 41893, the title of the invention is ``Handrail Corner Connection Member''), which can be referred to.

[Problems to be solved by the invention] Generally, metal handrails are manufactured as handrail assemblies and installed according to local conditions. Therefore,
In the example shown in Fig. 6, two posts are erected at the bending part of the handrail, and after the handrail is constructed, the ends of the caps are connected in accordance with the bending angle, but in this handrail,
Two struts are required for each bending point, which not only increases material costs but also adds weight to the design, which is not desirable. In addition, in the example shown in Fig. 7, a special member selected at a specific angle is
It is necessary to keep large quantities of various types in stock,
Generally speaking, it is difficult to handle this with off-the-shelf products because management becomes complicated. With such conventional technology, actual measurements at the site, adjustment of the product to the local situation, reprocessing, rework, etc., involved a great deal of effort and difficulty, and required skill and time.

[Means for solving the problems] Therefore, in view of the above-mentioned current situation, the present invention
It was developed to solve various problems, and the purpose is to propose a support that can be conveniently used for handrails that can be installed at any angle. It is divided into two parts in horizontal cross section, and one edge is pivoted to make the angle variable, while the other edge forms an overlapping part that slides depending on the bending angle, creating a variable side surface. This is a summary of what was done. The present invention provides a column that is erected at a corner position that is not a right angle, and has a handrail installed on the opposite side. The flange is pivoted along one vertical edge, and the edge of the flange that is not pivoted has an arc-shaped overlapping part centered on the pivot, and the outer surface of one overlapping part is connected to the other. It is characterized in that the width of this surface is variable by slidingly contacting the inner surface of the overlapping portion, and the angle of the side surface to which the handrail is joined is variable.

[Example] The angle-variable handrail support column of the present invention will be described in detail based on drawings showing examples. FIG. 1 is an elevational view of the bent portion of the handrail, FIG. 2 is a horizontal cross-sectional view of the same, and FIGS. 3 to 5 are horizontal cross-sectional views and detailed views of essential parts of the pillar of the embodiment. Reference numbers in FIGS. 6 and 7 are the same for the corresponding parts. In FIGS. 1 and 2, a Kasagi 3A is installed on the support 2 erected from the structure on the floor 1,
A handrail 5 is allocated between the lower rail 4 and the handrail assembly 6
has been configured. The variable angle strut of the present invention used in the bend of the handrail 3 is designated by the reference numeral 20.
This strut 20 consists of two halves 21 and 22 that are vertically divided, and each half 21 and 22 includes a symmetrical main body 23 having a roughly U-shape, a flange 24 on one side, and a flange 24 on the other side. A flange 25 and overlapping portions 31 and 3 extending from the flange 25 to the opposite side.
It consists of 2. The flange 24 of each half body part 21, 22 is formed with a winding part 26, 27 at the tip, and a pivot 30 is inserted into the flange 24 of both half body parts 21, 22.
It is centrally connected. The edge of the other flange 25 is
As the pivot 30 pivots, it becomes an opening, but overlapping portions 31 and 32 extend from the tips of the flanges 25 of both halves, and the overlapping portion 31 on one half 21 side
is bent so as to face the inner surface of the flange 25 of the other half 22. Other polymerized part 3
2 is bent and engaged separately from the flange 25 so as to be located further inside the overlapping portion 31, and both the overlapping portions 31 and 32 are connected to the aforementioned pivot 3.
In accordance with the rotation of the flange 25 when the two halves 21 and 22 pivot about 0,
The horizontal cross section is formed into an arc shape so that the inner surface of the overlapping portion 32 and the outer surface of the overlapping portion 32 are in sliding contact with each other. In a preferred embodiment of the present invention, as shown in FIG.
Furthermore, a locking notch 34 formed in the vertical direction is provided on the inner surface of the distal end of the overlapping portion 31 and preferably extends from the flange of the half portion 22 as shown in FIG. There is also a notch 3 on the inner surface of the tip of 25.
4 is provided protrudingly so that the sliding contact position is fixed.

In the above embodiment, the bending angle of the handrail 3 is 120~
165° is suitable, but FIG. 5 shows an example of correspondence with handrails having other angles. The strut 20a in Figure A is for angles of 90 to 120 degrees, and the strut 20b in Figure B is for angles of 165 degrees or more in cross section. To deal with such a case, the only way to deal with this is to change the configuration of the overlapping part. In the latter case, the overlapping portion 32 is rather unnecessary, and the overlapping portion 31 directly comes into sliding contact with the inner surface of the flange 25. The example shown in figure c shows an applied version of the example in figure b,
In this support column 20c, the overlapping portion does not extend from the flange 25, but is formed to have an arcuate cross section so that the overlapping portions 31 and 32 directly overlap with each other.

[Function] The function of the angle-variable handrail post of the present invention will be explained based on the construction process of the handrail assembly 6. The handrail assembly 6 can be manufactured by prefabricating the entire assembly and attaching it to the floor 1 using supports 20.The support posts 20 are first erected, and the handrails 3, lower rails 4, and balusters 5 on both sides are assembled in advance. After that, the method of constructing the pillar 20 between the pillar 20 and the adjacent pillar 2, the erection of the pillar 20 is preceded, the handrail 3 and the lower crosspiece 4 are constructed between the pillar 20 and the adjacent pillar 2, and then the handrail is installed in sequence. The order of how to assemble the child 5 is not limited. In the case of the third method, a pillar 20 with a corresponding angle range is selected and erected in advance, and both halves 21 and 22 are rotated around a pivot 30 to adjust the bending angle of the handrail 3. match. Within the openings of the flanges 25 of both half parts 21 and 22, the overlapping parts 31 and 32 slide and are adjusted to a predetermined bending angle, and the handrail 3 and the lower crosspiece 4 are supported by using joints (not shown). 20
to be joined to. This connection is carried out as usual in the main body 23.
All you have to do is touch it at right angles and fix it. The embedding and fixing of the support column 20 below the floor surface should be done with particular precision. Note that it is optional to use a separate curved plate to fill the difference in level that occurs at the ends of the overlapping parts 31 and 32. When the bending angle of the handrail 3 is closer to a right angle or closer to a straight line, the fifth

Use c.

[Effect of the invention] The variable-angle handrail support of the present invention is installed at a corner position that is not a right angle, and the support has a roughly U-shaped cross section in which a handrail is constructed on the opposite side. A symmetrical half body with , the outer surface of one overlapping part is in sliding contact with the inner surface of the other overlapping part, and the angle of the side surface to which the handrail is joined is variable, so one support is installed at the bent part of the handrail. This eliminates the need to install two supports, and also eliminates the need to keep a large number of special supports manufactured at specific angles in stock. In the strut of the present invention, one strut is divided into two halves, one side edge is pivotally connected, and various configurations can be adopted to form an overlapping part on the other side edge. Even in the overlapping part, a particularly large amount of material is not used, and the angle change due to the overlapping part is only caused by sliding by rotating around the axis, so the variable range of the angle of the Kasagi is The handrail assembly can be joined to accommodate any bending angle within the handle. Moreover, according to the pillar of the present invention, there is no need for precise measurements of the site or adjustment between the product and the site conditions, making it possible to reduce labor both in terms of production and construction. In addition, the formation of the polymerization part, which is a feature of the present invention,
Since it is manufactured as a molded material according to a small number of standards, this does not affect the overall construction cost, and there is no need for special precision in the precision of the product. In short, it can be said that the present invention, which solves the various problems of the struts at the bending portion, has a truly beneficial practical effect.
