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 is
A Kasagi main body 1 formed of an elastic soft vinyl chloride resin with an oval cross-sectional shape, and this Kasagi main body 1
It is composed of two rod-shaped metal core members 2 provided inside along the longitudinal direction, and the surface of each metal core member 2 has a large number of protrusions 4a provided along the longitudinal direction. The bonding surface 3 is made up of an uneven surface 4 formed by. In the handrail cap H of this first embodiment, the metal core material 2 is provided integrally with the cap body 1 when the cap body 1 is extruded, and the groove-like shape between each protrusion 4a of the metal core material 2 is Kasagi body 1 in the part
The resin forming the material enters the bonding surface 3 and the two are integrally bonded together at the bonding surface 3.

In the handrail cap H in this first embodiment, each metal core material 2 is formed of a solid rod-shaped body made of aluminum hard wire with a circular cross section of 5 mmφ with a protrusion provided on the periphery, and even if two pieces are used, Although each metal core material 2 is located on the neutral axis of bending in the direction and can be easily bent by hand bending, in the longitudinal direction, each metal core material 2 is located on the neutral axis of bending. The connecting surface 3 formed on the surface of the cap 2, that is, the uneven surface 4 composed of the protrusions 4a, is in close contact with the main body 1 of the cap, and the contact area between the two is significantly large, so that when bending The frictional resistance caused by the misalignment between the Kasagi main body 1 and the metal core material 2 is significantly increased, and the strength and rigidity of the Kasagi main body 1 is improved to such an extent that it cannot be bent by hand. Even when a load is applied in the circumferential direction to the handrail, the protrusions 4a constituting the uneven surface 4 prevent relative displacement between the cap body 1 made of an elastic material and the metal core material 2. Kasagi H does not twist.

Therefore, as shown in FIGS. 2 and 3, the handrail cap H of this first embodiment is attached to the bracket 5, for example, as shown in FIGS.
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. As a result, this handrail cap H exhibits extremely high strength and rigidity in the vertical direction, and the adjacent brackets 5
Even when the middle position of the handrail cap H between the handrails is grasped and force is applied in the circumferential direction, not only does it not produce any creaking noise, but the handrail cap H also exhibits high rigidity against twisting.

In addition, in the handrail Kasagi H of this first embodiment,
Since the bonding surface 3 provided on the surface of the metal core material 2 is an uneven surface 4 composed of protrusions 4a along the longitudinal direction, it can overcome the frictional resistance between the metal core material 2 and the Kasagi main body 1. This handrail cap H can be bent in the vertical direction by using a machine or tool that exerts the force of 1. This allows it to be used as a handrail cap for stair handrails that require vertical bending.

Moreover, FIGS. 4 to 9 show modifications of the first embodiment, and the handrail cap H shown in FIG. It has an uneven surface 4 consisting of a large number of grooves 4b formed along the length of the handrail, and compared to the handrail cap H shown in FIG. The friction resistance against shear caused by the pores becomes even higher, and the strength and rigidity in the vertical direction are correspondingly higher.Also, the diameter of the metal core material 2 is reduced by the concave grooves 4b against bending in the horizontal direction. It is easier to bend because it is smaller. Further, FIG. 5 shows that the bonding surface 3 provided on the surface of the metal core material 2 is an uneven surface 4 consisting of a spiral groove 4c carved in a spiral shape, and this metal core material 2 is used. When a handrail cap is manufactured, the handrail cap exhibits high strength and rigidity in the vertical direction, and at the same time, when a load is applied to the cap body 1 in the circumferential direction, the spiral groove 4c is connected to the cap body 1 and the metal. This can effectively prevent relative displacement between the core material 2 and the core material 2. Moreover, FIG. 6 shows a case where the metal core material 2 is formed by winding a metal wire material 4d in a spiral shape around the outer periphery of the core material body 2a, and the uneven surface 4 is formed by this wire material 4d. This handrail cap H has metal core material 2 shown in Fig. 5.
It achieves almost the same effect as a handrail hat made using the same method. Furthermore, the metal core material 2 shown in FIG. 7 has an uneven surface 4 which becomes a bonding surface 3 on its surface by twisting two core material members 2b together. The metal core material 2 shown is a plate-shaped metal core material 2 that is twisted to form an uneven surface 4 that becomes a bonding surface 3 on its surface, and the metal core material 2 shown in FIG. 2 is
A metal mesh material 4e is wound and fixed on the surface to form an uneven surface 4 which becomes a bonding surface 3.

Next, in FIG. 10, a handrail cap H according to a second embodiment of the present invention is shown. This handrail cap H is almost the same as the handrail cap H of the first embodiment, except that a rough surface 9 is formed as a bonding surface 3 on the surface of each metal core material 2. Also in the handrail Kasagi H of the embodiment, as in the case of the first embodiment above,
Kasagi main body 1 made of elastic material and metal core material 2
The handrail kasagi H is not twisted even if a load is applied to the kasagi body 1 in the circumferential direction. It is.

Moreover, FIGS. 11 to 13 show modified examples of the metal core material 2 in the handrail cap H of the second embodiment, and like the metal core material 2 shown in FIG. Rather than directly forming the rough surface 9,
The metal core material 2 shown in FIG. 11 is made by integrally wrapping a band-shaped body 10a having a rough surface 9 on at least the surface side around the outer periphery of the core material body 2a, and the metal core material 2 shown in FIG. A cylindrical body 10b having a rough surface 9 at least on the surface side is attached to the outer periphery of the core body 2a, and the metal core 2 shown in FIG. A sheathing body 10c having a C-shaped cross section and a rough surface 9 on the surface side is wound around the belt-like body 10a, the cylindrical body 10b, and the sheathing body 10c are made of metal, and the core material is welded by spot welding or the like. It is fixed to the main body 2a and forms a metal core material 2.

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 perfectly 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 described above, the present invention provides a handrail kasagi in which the kasagi body is formed 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 arranged inside the kasagi body. Since we have provided a bonding surface on the surface of the core material that is integrally bonded to the Kasagi main body,
The bond between the main body of the kasagi and the metal core material is improved, thereby improving the strength and rigidity of the handrail kasagi. We aim to save materials and reduce weight, and also prevent the creaking noise caused by relative misalignment between the cap body and the metal core material, and the twisting of the handrail cap wood that occurs at this time. It can be prevented.
