Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a handrail cover member attached to a handrail constructed along a staircase, a slope, a promenade, etc., which makes it easy to attach the handrail cover member to the handrail core material, and is easy to grip and not slip The present invention relates to a handrail cover member that provides a handrail.
[0002]
[Prior art]
Conventionally, as shown in JP-A-10-212808, JP-A-10-110512, and JP-A-8-326257, a handrail provided with a cover member on a handrail core is known. According to these handrails, a handrail cover member made of synthetic resin is provided on the entire outer periphery of the handrail core material, so that it is not cold when grasped compared to a bare handrail, and it fits comfortably in the hand. Is obtained, and the anti-slip effect is exhibited.
[0003]
Further, some handrail core members have the cross-sectional shape shown in FIG. 6A. However, such a handrail core member T has an opening formed in the lower surface with a groove portion M for inserting a mounting bracket. The tubular cover member surrounding the entire outer surface of the core member cannot be covered.
Therefore, as shown in FIG. 6B, there is one in which the end portion C1 of the cover member C is locked and attached to the edge of the groove portion M for inserting the mounting bracket, but the fitting feeling when grasped is improved. Therefore, when the cover member is formed of a soft synthetic resin, the locking force of the end portion C1 of the cover member C that engages with the edge of the groove portion M for inserting the mounting bracket is weak, and the cover member C is firmly attached to the handrail core material. The cover member C cannot be fixed to T, and the cover member C may be rotated during use or the cover member C may drop off.
[0004]
Furthermore, the soft synthetic resin has a large frictional resistance between the cover member and the handrail core material, and it is difficult to maintain the shape of the cover member itself, so the handrail core material is slid and inserted from the end of the cover member. It was not possible to adopt the mounting method.
Therefore, most of the conventional cover members are made of hard synthetic resin with low frictional resistance, and there is no choice but to sacrifice to some extent the fit that fits the hand when gripped and the anti-slip effect. It was a thing.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a handrail cover member that can be easily attached to a handrail, has a good fit when gripped, and can exhibit an anti-slip effect.
[0006]
[Means for Solving the Problems]
As a result of intensive studies in view of such circumstances, the inventors of the present invention are resin handrail cover members that cover the periphery of the handrail core material, and the handrail cover member has an olefin-based thermoplastic on the outer surface . elastomeric Tona Ri and forming a slip layer having a plurality of ridges on the outer surface lower, by forming the shape retaining layer made of a polypropylene resin on the inner surface, is obtained by achieving the intended purpose.
[0007]
[Action]
According to this invention, the cover member for the handrail has a two-layer structure of the anti-slip layer made of the olefin-based thermoplastic elastomer on the outer surface and the shape retention layer made of the polypropylene resin on the inner surface. Has a good fit when gripped, and has a plurality of ridges formed on the lower part of the outer surface , and therefore has an anti-slip effect.
Also, since the inner surface that comes into contact with the handrail is made of polypropylene resin , the friction resistance against the handrail core material is small, and the handrail core material can be slid and inserted from the end of the handrail cover member. The mounting operation of the member can be easily performed, and the locking force between the handrail core member and the cover member for the handrail can be increased, so that the cover member can be prevented from rotating or falling off.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the invention will be described based on examples.
1 to 5 show an embodiment of the handrail cover member of the present invention. In the figure, 1 represents a handrail, and the handrail 1 is attached to the upper end of a column 2 erected at a construction site. The handrail 1 is formed of a handrail core member 11 and a handrail cover member 12, and a mounting bracket 21 provided at the upper end of the column 2 is inserted into a mounting bracket insertion groove 111 formed on the lower surface of the handrail core member 11. The handrail core 11 is attached to the upper end of the column 2.
[0009]
The handrail cover member 12 is mounted around the handrail core member 11 and is formed of a synthetic resin material. The outer surface of the handrail cover member 12 has a two-layer structure of an anti-slip layer 121 made of a soft synthetic resin and an inner surface of a shape retaining layer 122 made of a hard synthetic resin. In the cross-sectional view of the handrail cover member 12 of FIG. 1, the portion outside the broken line is the anti-slip layer 121, and the inside portion is the shape retaining layer 122.
[0010]
The soft synthetic resin anti-slip layer 121 is formed of an olefinic thermoplastic elastomer such as ethylene propylene rubber, and the hard synthetic resin shape retaining layer 122 is formed of a polypropylene resin . Hand sliding cover member 12 is produced by two-layer extrusion molding method, the outer slip layer 121 and the inner shape holding layer 122 are integrally formed, it is not be peeled off.
[0011]
A locking edge 123 is formed on the lower edge of the handrail cover member 12, and the locking edge 123 is locked to the opening edge of the mounting bracket insertion groove 111 formed on the lower surface of the handrail core 11. A key-shaped engaging portion 124 is formed at an intermediate position on the inner surface, and an engaged portion 112 is formed on the outer surface of the handrail core 11 corresponding to the position of the engaging portion 124. The joining portion 124 engages with the engaged portion 112.
A plurality of protrusions 125 are formed in parallel at the lower portion of the outer surface of the handrail cover member 12 to enhance the anti-slip effect when the handrail 1 is gripped.
[0012]
According to the handrail cover member 12 of the present invention having the above-described configuration, the outer surface is formed of an olefin-based thermoplastic elastomer, so that the fit when gripped is good, and a plurality of protrusions are formed at the lower portion of the outer surface. Since the strip is formed, the anti-slip effect can be exhibited.
Further, since the inner surface is formed of polypropylene resin and the shape of the handrail cover member 12 is maintained, the handrail core member 11 can be slid and inserted from the end of the handrail cover member 12. The handrail cover member 12 can be easily attached. Furthermore, the handrail cover member 12 itself is not easily deformed, the locking force with the handrail core 11 can be increased, and the handrail cover member 12 can be prevented from rotating or falling off.
[0013]
【The invention's effect】
According to the cover member for the present invention handrail, the slip layer having a plurality of protrusions on and outside surface bottom Ri Tona olefinic thermoplastic elastomer to the outer surface is provided, the shape-retaining layer made of a polypropylene resin on the inner surface Since it is provided, it has the effect of preventing slipping, has a great effect in practice, such as facilitating the mounting operation to the handrail core material and increasing the locking force with the handrail core material.
