Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mounting structure for a decorative washer to be attached to the end of a handrail on a balcony, etc., and in particular to a mounting structure for a decorative washer for a handrail that is easy to install and has a good appearance. It's about structure.

Conventional Technology Generally, when installing a handrail with both ends fixed to a wall such as a balcony, decorative washers are used to maintain the beautiful appearance of the area where the end of the handrail meets the wall. Conventionally, in order to attach this decorative washer, the decorative washer was fixed to the mounting base using a fastener such as a screw.

Problems to be Solved by the Invention However, when attaching the decorative washer using fasteners such as screws as described above, not only does the process of attaching the fasteners become complicated, but
There was a problem in that the head of the fastener was exposed on the outer surface of the decorative washer, spoiling its aesthetic appearance. Particularly when handrails are installed outdoors or near water, there is a problem in that rust forms on the heads of the fasteners and the appearance deteriorates over time, and these problems have been solved. A mounting structure for decorative washers was desired.

Means for Solving the Problems The present invention has been made based on the above-mentioned needs, and the present invention solves the above-mentioned problems by fixing the above-mentioned problems to the outer circumference of a retaining ring that is resiliently pressed against the handrail. To provide a mounting structure for a decorative washer for a handrail, which is characterized in that a pressure contact piece that projects radially is formed, and the external decorative washer is attached to the handrail by pressing the pressure contact piece of the retaining ring against the inner wall surface of the decorative washer. This is what we are trying to solve.

action The above measures work as follows.

As shown in FIG. 1, the retaining ring 1 is elastically pressed onto the handrail 2 and mounted at an appropriate position on the handrail 2. A pressure contact piece 3 is provided protruding from the outer periphery of the retaining ring 1, and is adapted to press against the inner wall surface of a decorative washer 4 fitted onto the handrail 2 in advance. Therefore, by sliding the decorative washer 4 in the direction A in FIG. 1, the pressure contact piece 3 of the retaining ring 1 is elastically bent and connected to the decorative washer 4, so that the decorative washer 4 is placed in a predetermined position. It can be installed without using fasteners such as screws.

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

FIG. 1 is a perspective explanatory view showing the main parts of the mounting structure of a decorative washer for a handrail according to the present invention. 6.

The fixed washer 5 has a support part 5a and a flange part 5b, and the anchor bolt 7 is used as shown in FIG. 2, or the flange part 5b is welded to the reinforcement 8 of the wall surface 6 as shown in FIG. It is fixed to the wall surface 6 by such methods. This fixing washer 5 is for fixing the end of the handrail 2 to the wall surface 6, and is made of a covering material 2b made of synthetic resin on the outer surface of a core material 2a made of a steel pipe with a circular cross section.
The main slide 2 is formed by removing the covering material 2b from the end thereof, and is fixed to the fixing washer 5 by welding.

In addition, in FIG. 3, numeral 9 indicates mortar applied to the wall surface.

The decorative washer 4 attached to the end of the handrail 2 is
A thin plate material such as stainless steel material is drawn to form a circular shape when viewed from the front, and an inward rib is provided on the flat part 4a and is provided around the entire inner circumference to prevent damage to the covering material 2b of the handrail 2. The handrail 2 is inserted through a hole 4c having a protruding hole 4b.

The retaining ring 1 for fixing the decorative washer 4 is
It is made of a highly elastic material and is
As shown in the figure, a plurality of pressure contact pieces 3 are protruded radially outward from the outer periphery of a base 1b which is circular in front view and has a hole 1a formed in the center, and the inner periphery of the hole 1a. It is attached to the handrail 2 by a pressing piece 10 formed on the part. That is, the pressing piece 1 of the retaining ring 1
By making the inscribed circle of the end edge of 0 slightly smaller in diameter than the outer circumferential circle of the handrail 2, the pressing piece 10 is elastic as shown by the chain line in FIG. 4 when the retaining ring 1 is inserted into the handrail 2. Due to this restoring force, the pressing piece 10 presses the outer circumference of the handrail 2, and as a result, the retaining ring 1 is fixed to the handrail 2.

On the other hand, the pressing piece 3 of the retaining ring 1 has approximately the same slope as the inclined surface 4d of the decorative washer 4, and its tip edge is a circle with a diameter slightly larger than the inner diameter of the rising portion 4e of the decorative washer 4. It is formed to be located on the circumference. Therefore, after attaching this retaining ring 1 near the end of the handrail 2, the decorative washer 4 inserted into the handrail 2 in advance is slid (direction A in FIG. 1).
Then, the pressure contact piece 3 of the retaining ring 1 is elastically bent,
It is housed in the decorative washer 4, and due to this restoring force, the tip edge of the pressing piece 3 presses against the inner wall surface of the rising portion 4e of the decorative washer 4 (Fig. 4), and the decorative washer 4 is firmly fixed in a predetermined position. That will happen.

At this time, as shown in FIG.
By making the circumferential dimensions of the inscribed circles of the end edges of 0, 10, ... the same, the pressing piece 10 also plays the role of positioning the decorative washer 4, and prevents looseness after the decorative washer 4 is installed. It can be prevented.
Further, as shown in FIG. 4, by forming an arcuate bent portion 10a at the tip of the pressing piece 10, it is possible to prevent the covering material 2b of the cap 2 from being damaged. Furthermore, as shown in FIG.
3... are connected by the inclined surface 1c, the rigidity of the retaining ring 1 as a whole increases, and the fixing force of the decorative washer 4 can be increased.

FIG. 5 is a perspective explanatory view showing the case where the mounting structure of the handrail decorative washer according to the present invention is used for a handrail of a toilet for the handicapped, and the outer surface is covered with a synthetic resin covering material 2b to improve safety. A decorative washer 4 is attached to the abutment area between the handrail 2 and the wall surface 6 to improve the feel to the touch, and is attached with the above-described structure.

In the above embodiments, the handrail 2 in which the outer surface of the core material 2a is coated with the covering material 2b has been described, but the present invention is not limited to this, and the handrail 2 may be made of steel, aluminum, or the like. , furthermore,
The cross-sectional shape of the handrail 2 is not limited to a circular shape, and various cross-sectional shapes such as a semicylindrical shape can be used.

Effects of the Invention As explained above, in the present invention, the decorative washer is attached by pressing the pressure contact piece of the retaining ring that is resiliently pressed onto the handrail against the inner wall surface of the decorative washer. A decorative washer can be easily and firmly attached without using a child or the like. Furthermore, since the decorative washer can be attached to any position on the handrail, its range of use can be expanded regardless of the construction state of the wall surface. In addition, since the head of the fastener is not exposed to the outside, it is not unsightly, and there is no deterioration in appearance due to corrosion of the head, so it maintains its beauty for a long time, especially when used outdoors or in a toilet. be able to.
