Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a handrail joint used when connecting or fixing handrails, and particularly to a handrail joint useful for a handrail having a resin coating material.

2. Description of the Related Art The applicant previously proposed a structure for firmly fixing a resin-coated handrail (see Japanese Patent Laid-Open No. 62-101751). This is the fifth
As shown in the figure, a protrusion 20 is provided in the center of the handrail receiving portion 2 having a curved surface that matches the outer peripheral portion of the resin coating material 11, and the protrusion 20 is formed on the metal of the handrail 1. The core material 10 is brought into contact with the core material 10.

[Problems to be solved by the device]

The handrail joint in the above-mentioned conventional example has the effect of preventing wobbling by bringing the protrusion 20 projecting from the handrail receiving portion 2 into contact with the metal core material 10, and also the protrusion
By pressing 20 into the small hole 12 formed in the resin coating material 11 of the handrail 1, it is possible to improve the waterproof performance by using the resin coating material 11 contacting the protrusions 20 as a sealing material. However, when the diameter of the protrusion 20 is larger than the diameter of the small hole 12, as shown in FIG. 5 (b), the covering material 11 spread over the protrusion 20 is provided. However, there is a problem that the waterproof performance is not perfect or the appearance is poor due to a gap formed between the receiving portion 2 and the handrail 1 in contact with each other. The present invention has been made to solve such a problem, and an object of the present invention is to provide a handrail joint that is securely and closely fixed to the handrail 1.

[Means for Solving the Problems]

According to the present invention, the object is to provide a hollow pipe-shaped handrail 1 in which an outer surface of a metal core material 10 is coated with a resin coating material 11 as shown in FIGS. 1 and 2 corresponding to an embodiment. It has a handrail receiving portion 2 which is formed in a curved surface that matches the outer peripheral portion of the handrail, and has a protruding portion 20 protruding from the center portion to the surface of the metal core material 10 of the handrail 1. A handrail joint fixed to the handrail 1 by a fastening rod 3 reaching the hollow portion of the handrail 1 is characterized in that a concave groove 4 is formed around the projection 20 in the handrail receiving portion 2. It is achieved by

[Action]

Based on the above configuration, the handrail joint of the present invention is provided with a resin-coated handrail 1
In the state of being fixed to, the covering material 11 spread by the protrusion 20 is accommodated in the concave groove 4 around the protrusion 20.

【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2 show a handrail joint A configured as a bracket used when the handrail with wall 1 is installed along a wall surface, 5 is a wall surface, and 50 is embedded in the wall surface 5. Shows an anchor bolt. A support member 6 having a fixed seat 60 formed on the upper surface is fixed to the anchor bolt 50, and provides a receiving surface for the handrail joint A. The handrail joint A in this embodiment is formed in a hollow shape by projecting an outward flange 7 having an outer peripheral dimension substantially equal to the outer peripheral dimension of the fixed seat 60 of the support member 6 at the lower end portion. The loosely fitted nut member 8 is screwed onto the support member 6 so as to be fixed to the wall surface 5.
At the upper end of the handrail joint A, a handrail receiving portion 2 having a curved surface matching the outer peripheral portion of the handrail 1 is formed, and at the center of the handrail receiving portion 2, the covering material 11 of the handrail 1 is formed. A tapered projection 20 having a diameter slightly larger than the size of the formed small hole 12 and having a projection size substantially equal to the thickness of the covering material 11 is provided so as to project, and a groove 4 is formed all around the circumference. Has been done. The fastening rod 3 according to this embodiment is composed of a hollow connecting rod 31 which is formed with a slit 30 at its tip and which can be expanded outward, and a pin 33 which is inserted into a communication hole of the connecting rod 31. After inserting the connecting rod 31 into the insertion hole 21 formed at the center of the protrusion 20 of the handrail joint A, the pin 33 is inserted into the communicating hole of the connecting rod 31 to expand the tip of the connecting rod 31 outward. The handrail 1 and the handrail joint A are connected and fixed by tightening the nut 34 to prevent the handrail 1 from coming off. Therefore, according to this embodiment, when the handrail joint A is fixed to the handrail 1, the covering material 11 spread by the protrusion 20 is accommodated in the recessed groove 4 formed around the protrusion 20. A gap is prevented from being generated between the handrail receiving portion 2 and the handrail 1. When the handrail joint A of the present invention is used when the handrail 1 is installed in a bathroom as shown in FIG. 3, the handrail joint A is connected to the handrail 1 as shown in FIG. If the grease-like compound 9 is applied to the groove 4 at this time, the groove 4 functions as a pool of the compound 9,
Not only can the sealing performance be maintained for a long period of time and the corrosion of the steel pipe of the handrail 1 or the handrail joint can be prevented, but the amount of the compound 9 applied can be adjusted to prevent it from squeezing out. You can get the appearance. Although the present invention has been described above by taking the case where it is used as a bracket of the handrail 1 as an example, the present invention is not limited to such a case, and as shown in FIG.
Of course, it is used as an original handrail joint in the case of connecting in a character shape. In this case, the shape of the handrail joint A opposite to the handrail receiving portion 2 may be appropriately changed. The configuration of No. 3 can be appropriately changed in consideration of its use and required strength.

[Effect of device]

As explained above, according to the handrail joint of the present invention,
It is possible to reliably prevent the protrusion of the covering material due to the press-fitting of the protrusion into the covering material, and to obtain a good appearance and a reliable sealing performance.
