Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to handrail caps used for various handrails such as stair handrails, balcony handrails, rooftop handrails, window handrails, and wall handrails attached to the walls of corridors in hospitals, etc., and particularly, The present invention relates to a handrail hat whose main body is made of an elastic material such as a soft synthetic resin, a semi-hard synthetic resin, or a synthetic rubber, and a metal core material is provided inside the hat main body along its longitudinal direction.

The present inventors previously developed a cap body made of a bendable elastic material such as a soft synthetic resin, a semi-hard synthetic resin, or a synthetic rubber. It is bendable and consists of a metal core material that resists the elasticity of the Kasagi body and maintains its bent state after being bent.It is manufactured in a long length at the time of manufacture, and the length of the handrail mounting base is adjusted during installation. We proposed a handrail cap that can be cut to fit and bent to match the curved shape of the handrail mounting base.

This invention relates to the improvement of the handrail cap according to the above proposal, and by improving the bonding between the cap body made of an elastic material and the metal core material,
We aimed to improve the strength and rigidity of the handrail kasagi, and also tried to save and reduce the weight of the metal material used as the metal core material by the amount commensurate with this improvement in strength and rigidity. To provide a handrail cap that can prevent squeaks caused by relative misalignment of the handrail and twisting of the handrail cap that occurs at this time.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In FIG. 1, a handrail cap H according to a first embodiment of the present invention is shown.

This handrail kasagi H consists of a kasagi main body 1 made of elastic soft vinyl chloride resin and having an oval cross-sectional shape, and two rod-shaped metal cores provided inside the kasagi main body 1 along its longitudinal direction. 2, and an intervening member 3 is fixed to the surface of each metal core material 2, as shown in FIG.

This intervening member 3 is fixed to the surface of the metal core material 2 in a layered manner to suppress slippage between the metal core material 2 and the cap body 1, and in this embodiment, the outer circumference of the intervening member 3 is A band-shaped body made of a non-metallic material such as synthetic resin, which has a rough surface to increase the friction between it and the Kasagi main body 1, is integrally wrapped around the surface of the metal core material 2 using an adhesive or the like. It is attached and formed.

In the handrail cap H in this first embodiment, each metal core member 2 is formed of a solid aluminum bar with a circular cross section of 5 mmφ, and even if two are used, each metal core member 2 is Although the material 2 is located on the neutral axis of bending and can be easily bent by hand, in the longitudinal direction, the outer periphery of the strip that is the intervening member 3 has a rough surface. As a result, the contact area between the two becomes significantly large, and the frictional resistance due to shearing between the Kasagi main body 1 and the metal core material 2 during bending becomes significantly large.
Its strength and rigidity have been improved to the extent that it cannot be bent by hand, and the Kasagi main body 1
Even when a load is applied in the circumferential direction to the handrail body H, relative displacement between the cap body 1 and the metal core material 2 is prevented, and twisting does not occur in the handrail body H.

Therefore, the handrail cap H of this first embodiment is attached to the bracket 5 as shown in FIGS. 3 and 4, for example.
Using fixing means such as screws 6, the handrail mounting base 8, which is the wall surface of the corridor 7 of a hospital, etc., is cut to match its length and then bent laterally to match its curved shape. By doing this, this handrail cap H exhibits extremely high strength and rigidity in the vertical direction, and by grasping the middle position of the handrail cap H between the mutually adjacent brackets 5 and applying force in the circumferential direction. Not only does it not generate squeaks, but it also exhibits high rigidity against twisting of the handrail cap H.

In addition, in the handrail Kasagi H of this first embodiment,
Since the metal core material 2 and the Kasagi body 1 are in contact with each other via the rough surface of the intervening member 3, a force sufficient to overcome the frictional resistance between the metal core material 2 and the Kasagi body 1 is exerted. If you use machines and tools, you can make this handrail Kasagi H.
It can be bent vertically, so it can also be used as a handrail cap for stair handrails that require vertical bending.

5 to 7 show modified examples of the intervening member 3 in the handrail cap H of the first embodiment, and the intervening member 3 in FIG. 5 is a cylinder having a rough surface at least on the surface side. The intervening member 3 in FIG. 6 is a covering with a C-shaped cross section with a rough surface at least, and the intervening member 3 in FIG. 7 is cloth. There is.

In this case, the intervening member 3 shown in FIGS. 5 and 6 is made of a non-metallic material such as synthetic resin, and is fixed to the metal core material 2 with a suitable adhesive or the like.

Next, in FIG. 8, a handrail cap H according to a second embodiment of the present invention is shown.

This handrail cap H is also the handrail cap H of the first embodiment.
However, the intervening member 3 in this embodiment is made of a material that completely prevents slipping between the metal core material 2 and the cap body 1.

That is, the intervening member 3 in this embodiment is
The intervening member 3 is an adhesive layer applied to the surface of the Kasagi body 1, and the Kasagi body 1 and the metal core material 2 are integrally bonded to each other.

Furthermore, in the handrail cap H of the third embodiment shown in FIG.
It is made of foamed synthetic resin or hard synthetic resin that can be bonded well with other materials.

Note that the intervening member 3 used in this embodiment may be provided in advance on the outer periphery of the metal core material 2, or may be formed on the outer periphery of the metal core material 2 when extruding the Kasagi main body 1. You can do it like this.

In each of the above embodiments, the handrail cap H in which the cross-sectional shape of the cap body 1 is oval and uses two metal core materials 2 has been described, but the present invention is not necessarily limited to this. Regarding the cross-sectional shape of the Kasagi main body 1 and the number of metal core members 2 used, for example, a handrail with a perfect circular cross-section and one metal core member 2 in the center as shown in FIG. The present invention can also be applied to Kasagi H, and any cross-sectional shape or number of pieces used can be adopted.

As is clear from the above description, according to the handrail cap according to the present invention, soft synthetic resin, semi-hard resin,
A Kasagi body made of elastic material such as synthetic rubber,
In this handrail kasagi, which has a metal core provided inside the kasagi main body along its longitudinal direction, the surface of the metal core has a space between the metal core and the kasagi main body. By interposing a layered intervening member that suppresses or prevents slipping, the bond between the cap body and the metal core material is improved, thereby improving the strength and rigidity of the handrail cap. This improvement in strength and rigidity is commensurate with the reduction of the metal material used as the metal core material and weight reduction, and furthermore, by creating a relative misalignment between the Kasagi body and the metal core material. It is possible to prevent the creaking noise that occurs and the twisting of the handrail hat wood that occurs at this time.
