DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin-coated handrail made of an extruded aluminum alloy material coated with a synthetic resin and a method of applying the same.

[0002]

2. Description of the Related Art Aluminum handrails are durable, lightweight, easy to handle, and excellent in appearance and strength.
Currently heavily used. However, since it is a metal with low specific heat and high thermal conductivity, it is extremely heated by the midsummer sun, and there is a danger of burns by touching it.On the contrary, in a cold region, there is a danger that it will be extremely cooled in midwinter and suffer from frostbite. There was a problem.

[0003] The appearance is good compared to the case of iron which is easily rusted because the luster of the alumite is maintained. However, since the color is limited by the alumite technology, a particularly colorful color may be adopted. could not. Therefore,
The present inventors have tried to solve such a problem by resin coating.

Conventionally, in order to apply a resin coating to a long member, a shrink means for inserting a heat-shrinkable resin tube and shrinking by heating is used. However, if there is no problem if it is used in a simple cylindrical shape like a clothesline,
It is difficult to apply to objects that are connected to other members for assembly, such as handrails.

In general, when assembling a handrail, it is not possible to drill through holes or operation holes for screws such as screws or bolts from the appearance of the handrail, so that a handrail mounting base is provided at the upper end of the handrail support. The handrail is attached so that the eyeboard is screwed in advance, and is attached to the eyeboard.

[0006] Since the handrail is attached to the eye panel and assembled as described above, the cross-sectional shape is usually an inverted channel shape, and the above-mentioned shrink means is used to maintain this shape. Can not. In addition, since the pair of left and right eyepieces and handrails are formed with a pair of right and left locking claws or engaging claws in a non-return relationship, the shrinking means cannot be taken to prevent the loss of the locking relationship.

[0007]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention not only makes it possible to easily perform resin coating, but also does not hinder the connection with the eyeboard.
An object of the present invention is to provide a resin-coated handrail whose resin coating is stabilized by the bonding and a method of applying the same.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is based on an extruded aluminum alloy profile having an inverted channel shape and having pockets and engaging claws formed inside the opening on both sides. Extruded synthetic resin material that has a handrail material and a bent piece folded at both ends inside the opening edge of the handrail material, and provided with bulges at the ends of both bent pieces to fit into pockets of the handrail material. A resin covering material, and a perforated plate having hanging ribs on both sides for holding down a refraction piece of the resin covering material, and a hooking claw projecting on an upper surface of which a hook for engaging a handrail material is hooked in a non-return relationship. A resin-coated handrail is provided.

According to the above configuration, in the combination of the handrail material and the resin coating material, the combination is temporarily stopped by fitting the bulging portions at both ends of the resin coating material into the pockets of the handrail material. , The combination is fixed in the connection with the eyeboard,
It becomes a stable state where the resin coating material is never peeled off. Regarding the assembling procedure, it is desirable to use the following construction method.

That is, according to the method for applying a resin-coated handrail of the present invention, a resin coating material made of an extruded synthetic material is rolled around the periphery of an inverted channel handrail made of an extruded aluminum material, and both ends thereof are joined. Fold it inside of the handrail material and temporarily fix it.At the site, install a balustrade on the upper end of the handrail post, then attach the balustrade to the balustrade and join it, and at the same time, coat the resin at both ends of the balustrade An object of the present invention is to provide a method of applying a resin-coated handrail, which comprises holding down both ends of a material so as not to come off.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a resin coating material 3
Unless the material of the synthetic resin is not inconvenient for coating,
There is no particular limitation as to heat shrinkability. Also,
By adding pigments, for example, red, yellow, green,
Colors can be freely selected, such as blue.

The attachment of the eye plate 2 to the handrail support 10 is not particularly limited, and it is desirable to attach the eye panel 2 in advance as in the embodiment, but it is also possible to attach it later using a connecting bracket. Then, the handrail material 1, the eye panel 2, and the resin coating material 3 can be integrally assembled and then attached to the handrail support 10.

[0013]

As described above, according to the present invention, since the combination of the handrail material and the resin coating material is only temporarily fixed, the resin coating can be easily performed. Not only does the resin coating material not hinder the connection with the eye panel, but on the contrary, the combination determines the combination of the handrail material and the resin coating material. There is. In addition, there is an advantage that when the resin coating material is deteriorated due to mere assembling, it can be replaced.

In the resin-coated handrail, the danger of burns due to the heating of the sun and frostbite due to the cold can be prevented by the resin-coated material, and the color can be freely selected. Also,
In the method of applying the resin-coated handrail, it is possible to assemble in a simple manner.
