DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail for preventing a part of the outer periphery of a hollow member made of metal or synthetic resin which is mounted on a stairway, a corridor or other places for construction from using, in order to prevent slippage during use. The present invention relates to a handrail in which an uneven portion is formed in a part in the longitudinal direction, and a uniform coating layer is applied on the entire outer periphery of the handrail.

[0002]

2. Description of the Related Art In general, handrails used for this type of architectural stairs, corridors, and the like are made of wood made in a circular shape in the longitudinal direction, directly using metal pipes, or synthesized on the outer periphery of metal pipes. At present, it is common practice to use a resin-fitted material by handrail.

[0003] Among the above-mentioned prior arts, the use of wood in the former is problematic in that the strength is generally weak, the production is extremely troublesome, and mold and the like are easily generated. There is. In the latter case, the metal pipe or the outer periphery coated with a synthetic resin has a problem in that it is very slippery and dangerous, and there is a problem that an injury, a cut or the like occurs when hit. The present invention has been made in view of such conventional problems, and a main object of the present invention is to provide a handrail body having a hollow member made of synthetic resin or metal, the outer periphery of which is attached to the hollow member. A corrugated shape is formed by a thick protrusion and a thin protrusion made of synthetic resin in a part of the longitudinal direction. A coating layer is applied to the entire outer periphery of the hollow member, the thick protrusion, and the thin protrusion to form a projecting step and a concave step alternately. In addition, a flat portion for a cutting portion which is partially discontinuous between the protruding step portions and the concave step portions is formed. Another object of the present invention is to provide a non-slip handrail in which a metal tube is inserted into a hollow member to secure strength.

[0004]

According to the present invention, in order to achieve the above object, a handrail main body is formed inside with a longitudinal hollow member made of synthetic resin or metal, and the hollow member has a hollow member. A thick projection and a thin projection made of synthetic resin are formed in a wavy shape in the longitudinal direction of a part of the outer periphery. By coating a coating layer on the entire outer periphery of the hollow member and the thick and thin projecting portions, projecting steps and concave steps are alternately formed. In addition, a discontinuous flat portion for cutting is formed at an alternate part of the above-mentioned protruding step portion and concave step portion. Further, a reinforcing metal pipe is inserted into the hollow member.

[0005]

The present invention has the above-mentioned structure, and its production and use will be described. The hollow member (2) is passed through the inside of the die from the horizontal direction, and the die of the die from the first extruder is used. By the lifting and lowering action of the mold of the lifting rod of the variable driving device from below, the thick protrusions (3) and the thin protrusions (4) are alternately formed in a wave shape on a part of the hollow member (2) in the longitudinal direction. The hollow member (2), the thick protrusion (3), and the entire outer periphery of the thin protrusion (4) are formed continuously with a synthetic resin from a mold die from a second extruder. A handrail is formed by applying a coating layer (5) so as to be uniform.
Further, the cutting is facilitated by the flat portion (8) formed discontinuously. Further, a metal tube (9) is inserted into the hollow member (2) for reinforcement to strengthen it.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a handrail body according to an embodiment of the present invention; FIG.
The hollow member (2) has a thick protrusion (3) which is formed into a corrugated shape with a constituent material of synthetic resin on a part of the outer periphery in the longitudinal direction.
And the thin protrusions (4) are formed alternately and continuously.
Next, the exposed portion of the hollow member (2) and the thick protrusion (3)
And with a synthetic resin same effect quality throughout the outer periphery of the thin projecting portion (4), Yotsute uniform film layer (5) to be deposited thick-
A projecting step (6) and a concave step (7) are formed in the longitudinal direction on the corrugated portion above the thin projecting section (3) and the thin projecting section (4) .

Further, what is shown in FIG. 5 described in claim 2 is such that the projecting step (6) and the concave step (7) provided in the longitudinal direction of the handrail body (1) are alternately continued. An example in which a flat portion (8) which is convenient for cutting, for example, is formed at a predetermined position in the middle of the cutting is shown. A metal tube (9) is inserted into the hollow member (2) of the handrail body (1) for reinforcement as shown in FIG.

In the embodiment shown in FIG. 6, the handrail is an elliptical handrail (10), and the hollow member is an elliptical member (12).
A thick protrusion (13) and a thin protrusion are formed on a part of the outer periphery in the longitudinal direction, and a coating layer (14) is applied to the entire outer periphery. In the embodiment shown in FIG. 7, the hollow member (2) inside is a hollow rectangular member (15).
Thick protrusions (16) and thin protrusions are alternately formed on one side in the longitudinal direction of the outer periphery, and a coating layer (17) is applied to the entire outer periphery. In addition, as a constituent material of the synthetic resin of the present invention, materials such as an olefin-based synthetic resin, a vinyl chloride resin, a polystyrene-based synthetic resin, and a nylon-based synthetic resin are used.

[0009]

According to the present invention, unlike a conventional one in which a synthetic resin is applied to the outer periphery of a wood or metal pipe or a metal pipe, a handrail does not slip and a grip portion can be securely formed. It has good stability and good feeling, and has a very good effect on aesthetics. It has a remarkably novel shape and sufficient toughness as compared with conventional wood and the like. Since the thick protrusions and the thin protrusions made of synthetic resin are alternately formed at predetermined intervals in a wavy shape in a longitudinal direction of a part of the outer periphery of the hollow member inside the handrail main body, uneven sliding is performed. There is an effect that the stopper can be easily formed. Furthermore,
For the hollow member and the thick protrusion and the thin protrusion, a uniform coating layer is applied to the entire outer periphery thereof to form the projecting step and the concave step alternately, thereby preventing the protrusion from slipping. The step portion and the concave step portion become a double layer and have an effect of being remarkably toughened and being surely and beautifully finished. In addition, by forming a discontinuous flat portion on the wavy part of the projecting step and the concave step formed on the handrail body, the cutting position with respect to the dimensions can be cut accurately and in a good shape. is there. Further, the metal tube inserted into the hollow member of the handrail main body has an effect that the entire handrail main body is significantly toughened and can be used safely.
