Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a handrail provided on the wall surface of a bathroom, a washroom, a toilet for the physically disabled, etc., for example.

[Conventional technology]

Handrails installed in bathrooms and the like are most commonly constructed by connecting a plurality of pipes, mainly made of stainless steel, and fixing the combined pipes to a wall using a bracket.

In addition, as a connection structure for a pipe, for example, a socket for fitting an end of the pipe is used, a screw inserted in the radial direction is screwed into the socket, and the screw is pressed against the circumferential surface of the pipe to fix it. In addition, connection using a socket with a thread cut on the end of the pipe and a female thread provided on the inner periphery, or a connection using a nipple or the like is also possible.

[Problem that the invention attempts to solve]

Incidentally, a bracket for fixing a handrail to a wall often has a fixing structure in which a flange is provided at the base end and screws are screwed into the wall. In order to hide the flanges and screws, it is common practice to integrate the cover with the bracket.

Since this cover is disposed so as to surround the bracket, one condition is that it be annular. Depending on the installation location, it may be necessary to fix the bracket to the wall and then attach it to the cover, so a structure in which the cover can be opened by cutting a slit is used. As described above, in the case where the slit is provided, the cover must be made of an elastic material and fixed to the wall so as to surround the bracket.

However, since the slit portion is first opened and the cover is attached to the bracket, the cover is easily opened due to elastic strain. Therefore, in order to restrain the entire cover and prevent it from opening, it is necessary to secure the cover itself with screws or rely on some other fixing structure. However, fixing the cover with screws contradicts the original purpose of providing the cover. Further, even if other fixing structures are adopted, a design is required that does not complicate attachment and detachment of the cover.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a structure for attaching a cover to a handrail, which does not cause the slit portion of the cover to widen or rise from the wall surface.

[Means for solving problems]

In order to achieve the above object, the present invention provides a handrail in which a flange is connected to a bracket or a pipe itself and is fixed to a wall surface via the flange. a receiving seat made of synthetic resin, which is detachable from the receiving seat, and an annular cover made of synthetic resin that is incorporated around the bracket or tube to hide the receiving seat and the flange; A slit is cut in the cover in the radial direction, a pair of protrusions are formed at positions sandwiching the slit, and the receiving seat is further provided with a restraining hole into which the protrusion fits.

〔Example〕

Hereinafter, the features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

FIG. 1 is a partially cutaway plan view of a handrail showing an embodiment of the present invention.

The handrail is constructed mainly of two straight pipes 1, a pair of curved pipes 2 connected to the ends of these pipes, and a bracket 3 disposed at a portion connecting the straight pipes 1.

A bolt shaft 3a is protruded from both sides at the tip of the bracket 3, and the bolt shaft 3a is screwed into a bush 1a provided at the end of the straight pipe 1, thereby connecting the straight pipes 1 through the bracket 3. . Further, a bushing 1b is provided at the other end of the straight pipe 1, and a female thread 2a is formed on the bent pipe 2, and a bolt 1c is screwed into the bushing 1b and the female thread 2a to connect the straight pipe 1 and the bent pipe. Connect pipe 2.

A metal flange 4 is fixed to the end face of the bracket 3 facing the wall surface A with screws 4a, and this flange 4 is fixed to the wall surface A with fixing screws 4b to support the central portion of the handrail. The flange 4 is housed in a receiving seat 5 which is fixed integrally with the flange 4 to the wall surface A by fixing screws 4b, and a cover 6 is detachably attached to the receiving seat 5.

FIG. 2a is a plan view of the receiving seat 5, and FIGS. 2b and 2c are longitudinal cross-sectional views taken in the direction of the - line arrow and the -line arrow direction in the same figure a.

The receiving seat 5 is formed into an annular body made of synthetic resin, and has a rim 5a standing upright on its edge over the entire circumference, and has a screw hole 5 inside thereof into which a fixing screw 4b is inserted.
b is opened in an oval shape. Furthermore, engaging claws 7 for elastically engaging the cover 6 are provided at two locations on the edge higher than the rim 5a, and a restraining hole 8 is formed at one location to prevent the cover 6 from spreading. .
An engaging portion having the same shape as the engaging claw 7 is formed on the outer peripheral surface of the cylindrical portion 9 having the restraining hole 8 . That is, the shape of the outer circumferential surface of the engaging claw 7 and the cylindrical portion 9 is a tapered surface 1 whose outer diameter increases from the upper end toward the lower end.
0, and an engaging surface 11 whose outer diameter decreases from the terminal end of this tapered surface 10 is formed.

FIG. 3a is a bottom view of the cover 6, and FIG. 3b is a bottom view of the cover 6.
FIG. 3 is a longitudinal cross-sectional view taken along the - line arrow in FIG.

The cover 6 has an opening 6a through which the bracket 3 is inserted.
It is an annular body provided with a slit 12 from the opening 6a to the outer peripheral end. By providing such an opening 6a and slit 12, the cover 6 can have the slit 12 wide open, and can also be attached to the bracket 3 fixed to the wall surface A. Further, at two locations sandwiching the slit 12, protrusions 13 are provided to fit into the restraining hole 8 of the receiving seat 5. Further, a locking surface 15 that engages with the engaging surface 11 of the cover 6 and a tapered surface 16 for facilitating installation are formed on the inner periphery of the rim 14 provided around the entire edge. There is.

Note that FIG. 5 shows a perspective view of the cover 6 and the receiving seat 5. Similarly, the bent pipe 2 is fixed to the wall surface A by the flange 4, the receiving seat 5, and the cover 6.
Its mounting structure is almost the same as that of the bracket 3.

In the above configuration, the handrail that integrates the straight pipe 1 and the curved pipe 2 is fixed to the wall surface A by the flange 4 and fixing screws 4b. Note that the cover 6 placed on the bent pipe 2 can escape to the straight pipe 1 side when it is fixed to the wall A with the fixing screws 4b on the flange 4, so it can be installed while being assembled around the bent pipe 2 in advance. is possible. Therefore, as the cover 6, a normal type without the slit 12 can be used as is.

Once the handrail has been fixed, twist the cover 6 in the axial direction to widen the gap between the slits 12, insert the bracket 3 through the widened slit 12, and move the cover 6 around the bracket 3. Incorporate into.

Next, the cover 6 is fitted into the receiving seat 5 while aligning the protrusion 13 of the cover 6 with the restraining hole 8 of the receiving seat 5. In this fitting, first, the tapered surface 16 of the cover 6 is connected to the tapered surface 10 of the engaging claw 7.
At this time, due to the elastic deformation of the rim 14 of the cover 6 expanding and the diameter of the engaging claw 7 contracting,
The cover 6 can be integrated with the receiving seat 5. Then, as shown in FIG. 4, the locking surface 15 of the cover 6 engages with the engaging claw 7 and the engaging surface 11 of the cylinder part 9,
is restrained by the catch seat 5. At the same time, the protrusion 13 of the cover 6 fits into the restraint hole 8 to prevent the slit 12 from widening.

As described above, even if construction cannot be performed without providing the slit 12, the cover 6 is restrained in its axial direction by the engaging surface 11 and the locking surface 15,
Can be fixed around 3 brackets. Furthermore, since the protrusion 13 is restrained within the restraint hole 8, the cover 6 is prevented from expanding in the circumferential direction across the slit 12. Therefore, even if the cover 6 is provided with the slits 12, the appearance can be improved without increasing the gap between the slits 12 after construction.

[Effect of idea]

As explained above, in the handrail of the present invention, a cover is provided with a protrusion at a position sandwiching the slit, and a restraining hole is provided in which the protrusion fits into a receiving seat of a flange fixed to the wall surface side. The cover is restrained in the axial direction by the engagement surface between the cover and the peripheral surface of the receiving seat. Therefore, since the protrusion is held in the restraining hole, the circumferential direction of the cover is restrained, and the cover can be used without increasing the gap between the slits after construction. In addition, the cover and the receiving seat can be connected using elastic deformation of the synthetic resin without using mechanical means such as screws, and construction can be easily performed.
