TECHNICAL FIELD OF THE INVENTION
The present invention relates to handrails installed in corridors, stairs, and the like.
[0002]
[Prior art]
Conventionally, handrails installed in corridors, stairs, etc., are formed by inserting a cylindrical connecting member equal to the inner shape of the cross section of the handrail material at the abutting end of two handrail materials, and having an annular shape equal to the cross-sectional outer shape of the handrail material. In a state where the cover is fitted, it is placed on the handrail receiving fitting, and a male screw is fastened and fixed to a screw hole formed in the connecting member from below the handrail receiving fitting.
[0003]
However, in such a conventional handrail, since the connecting member is formed in a tubular shape equal to the inner shape of the handrail material, when the connecting member is inserted into the butted ends of the two handrail materials, is it installed exactly in the middle? It is difficult to check whether the holes are unevenly distributed on one side, and it takes time and effort to align the screw holes formed in the connecting member with the through holes at the butted ends of the handrail material and the through holes of the handrail receiving bracket. There is a disadvantage that it is inferior.
Also, since the cover fitted to the outside of the butted end of the two handrails is annular, the handrail must be inserted through the handrail before attaching it to the handrail receiving bracket, and When screwing the butting end and the handrail receiving fitting, it is troublesome to perform positioning so as to just straddle the butting end, resulting in poor workability.
[0004]
[Problems to be solved by the invention]
The present invention solves the above problems and provides a handrail excellent in workability.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the handrail of the present invention has a connecting member inserted inside a butt end of two handrails placed on a handrail receiving bracket, and the connecting member has a groove-shaped or plate-shaped main body, A female screw formed by welding a nut to both ends thereof, and an adjusting hook formed by being cut and raised substantially at the center of the main body, and a male screw is tightened to the female screw of the connection member from below the handrail bracket. The butt ends of the two handrails are fixed, a cover is provided on the butt ends, and the cover is formed of a band-shaped body bent along the outer periphery of the butt ends of the two handrails. A supporting portion and a handrail receiving portion for supporting the handrail material. The supporting portion and the handrail receiving portion are rotatably connected by bolts, and both ends of the cover are locked to the handrail receiving portions via the bolts. what is A.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the figure, 1 is a handrail material, 2 is a connecting member, 3 is a cover, and 4 is a handrail receiving bracket.
[0009]
The handrail material 1 is a long body such as a circle, an ellipse, a square, and a sector in section, and is made of a metal such as stainless steel, aluminum, or brass, or a synthetic resin such as polyethylene, polypropylene, ABS resin, or polyvinyl chloride. A coated steel pipe, FRP pipe, wood or the like is used. In the case of a synthetic resin-coated steel pipe, wood powder or the like may be mixed into the synthetic resin layer to give a wood-like texture, or irregularities may be formed to make it easier to grasp.
[0010]
Further, the handrail material 1 is installed with two pieces facing each other in a butt shape, and a through hole for a screw is formed near the end.
[0011]
The connecting member 2 is inserted inside the butted ends of the two handrails 1 and 1 and connects and integrates both handrail ends. The connecting member 2 includes a main body 21 and a female screw 22, and the main body 21 has a groove. Mold or plate steel is used. At least one female screw 22 is provided at each end of the main body 21, and a nut is welded to the main body 21. An adjusting hook 23 is formed at substantially the center of the main body 21 so that the main body 21 can be hooked and slid with a tip of a driver or the like.
[0012]
The cover 3 is provided outside the abutting end of the two handrails 1 and 1 and is usually formed of a belt-like body bent along the outer periphery of the handrail, and is made of a flexible material such as rubber or synthetic resin. Besides being made from a certain material, it may be made of metal such as stainless steel, aluminum, brass and the like.
The cover 3 is bent into an inverted U shape, fitted into the outer periphery of the handrail member from above, and has both ends reaching the handrail receiving bracket 4.
[0013]
The handrail receiving bracket 4 is installed on a wall surface of a building, a side surface of a column, or the like, and supports the handrail material 1. The handrail bracket 4 includes a support portion 41 along the wall surface, the side surface, and the like, and a handrail receiving portion 42 supporting the handrail material 1. Become.
[0014]
The support portion 41 and the handrail receiving portion 42 are separately manufactured by cast iron, aluminum die casting, or the like, and are rotatably connected by bolts 43 so as to be suitable for installation on a stair or the like with a gradient. Has been done. Note that both ends of the cover 3 are locked via bolts 43.
[0015]
【The invention's effect】
As described in detail above, in the handrail of the present invention, a connection member having a female screw is inserted inside the abutting end of two handrails placed on the handrail receiving metal fitting, and the female screw of the connecting member is inserted from below the handrail receiving metal fitting. Since the male screw is tightened to fix the butted end of the two handrails, the connecting member can be seen from the gap between the two handrails, the female screw of the connecting member, the through hole at the end of the handrail, and the handrail receiving bracket. Alignment with the through hole is easy, and the workability of assembly is good.
[0016]
In addition, since the cover is provided at the butted end of the two handrails after the two handrails are fixed to the handrail receiving bracket, the cover can be accurately set at the butted end of the two handrails, and it is possible to precisely install the cover. And can be finished.
[0017]
Further, since the cover is formed of a belt-like body bent along the outer peripheries of the two handrails, there is no gap between the cover and the outer peripheries of the handrails, so that the appearance is good.
[0018]
Furthermore, since the adjusting hook portion substantially centrally of the connecting member is formed, insert a screwdriver or the like connecting member inserted in the abutting ends of the two handrail material from the gap of the two handrail material, for the adjustment it is possible to slide the connecting member hooked on the hook portion, it is easy positioning of the connecting member.
