The grip bar 2 and the bracket 3 of the handrail body 1
Are integrally formed, and a mounting device for the wall surface W is built in so as not to be exposed to the outside. Therefore, there is a connecting portion between the gripping bar portion and the bracket portion, which are separate bodies, and a mounting device that is exposed. Therefore, it is possible to prevent the handrail components from being deteriorated due to flooding. Also, since there is no connecting device between the gripping bar portion 2 and the bracket portion 3 and no mounting device to the exposed building wall surface, the user does not come into contact with gaps between parts or mounting brackets, and only a smooth surface. The feeling of use is improved because the user grips. Furthermore, the appearance of the entire handrail is elegant with little mechanical resistance. In particular, since the building handrail shown in FIG. 1 has the bracket portions 3 and 3 formed at both ends of the gripping bar portion 2, the handrail main body 1 is manufactured integrally as a whole.
It is possible to obtain a mechanically durable building handrail having good waterproofness and low cost.

2 to 5, the work of attaching the handrail is performed in a state in which the space 12 for operating the anchor is exposed, that is, in a state in which the cap 4 is removed. In addition, sanitary fixtures such as bathtubs, toiletries, and toilet bowls may be deteriorated or damaged due to the effects of moisture, heat, etc., or the mechanical effects of direct contact with the user, and there is often an opportunity to repair or replace new sanitary fixtures. However, handrails installed in close proximity to sanitary fixtures may hinder the repair and replacement of new sanitary fittings, and in some cases it may be necessary to remove the handrails for work. The operation of the means for attaching to the wall surface W must be performed with 4 removed. According to the present invention, when the cap 4 is covered, it is possible to maintain a sufficient internal watertightness and at the same time prevent the cap from being accidentally dropped off, and to remove the cap 4 intentionally, remove the cap 4 by a simple operation. The main feature of the engagement structure of the cap 4 is that it is possible to do this.

That is, in the convex concave portion 7 of the handrail main body 1,
A top support recessed groove 13 is formed at the top end, a pair of shoulder support recessed recesses 14 and 14 are formed on both sides of the shoulder, and a pair of end support recesses are formed on both sides of the mounting plate 5 which is the end. Recesses 15, 15 are formed, and at the outer end of the mounting plate portion 5, a substantially vertical cut end surface 16 is formed in the mounting plate portion 4, while the cap 4 is engaged with the top support groove 13. A top claw 17 protrudes from the inner surface of the top end so that the shoulder support recesses 14 and 14 can be formed.
A pair of sagittal claw pieces 18, 18 tapering in the apical direction are formed on the inner surfaces on both sides of the shoulder portion so as to be able to be locked. Pieces 19, 19 are formed. The top claw 17, the sagittal claw 18, and the end claw 19 of the cap 4 are locked in the top support recess 13, the shoulder support recess 14, and the end support recess 15 of the handrail main body 1, respectively. When the cap 4 is fitted into the convex concave portion 7 of the handrail main body 1, the outer surface of the cap 4 matches the outer surface of the handrail main body 1, reveals a smooth surface, and a central portion on the end side of the cap 4. Numeral 20 keeps a non-contact space with respect to the outer surface of the cut end face 16, and a peripheral edge 21 of the cut end face 16 is covered in a contactable proximity state.

When the cap 4 is fitted and covered on the handrail body 1 after the handrail body 1 is attached to the wall surface W, the end edge of the cap 4 is aligned with the edge of the mounting plate portion 5, and the cap 4 is directly held by the handrail. When the cap 4 is pushed in the direction of the main body 1, the elasticity of the cap 4 causes the top claw piece 17, the sagittal claw piece 18 and the terminal claw piece 19 of the cap 4 to move into the top support groove 13, the shoulder support concave groove of the handrail body 1. The cap 4 is engaged with the handrail main body 1 in a single operation by being locked in the recess 14 and the terminal side support concave recess 15. Since the cap 4 is in close contact with the convex concave portion 7 of the handrail main body 1 in a state of being fitted and covered, the cap 4 is deformed by an external load on the vicinity of the sagittal claw pieces 18, 18 and the cap 4 is locked. It does not come off and is not flooded inside, and the mounting device including the anchor screw 12 existing inside is not deteriorated. Also, since the surface of the cap 4 forms the same plane as the surface of the handrail main body 1, the user grips the smooth handrail surface in which the grip bar 2 and the bracket 3 are integrated without being aware of the presence of the cap. can do. Unless the cap 4 fitted and covered is intentionally removed, the fitted state of the cap 4 to the handrail main body 1 is maintained by using its elasticity, so that the cap 4 does not fall off carelessly. In addition, if the locking protruding piece 22 is provided on the inner surface of the cap 4 to be in contact with the edge of the gap 6 for operating the anchor, the fitting position can be more reliably held when the cap 4 is fitted.

When the fitted cap 4 is intentionally removed, the end-side central portion 20 of the cap 4 is pressed against the elasticity. Then, since the center portion 20 of the terminal end is kept in a non-contact state with the cut end face 16 of the mounting plate 5, the cut end face 1
6 and at the same time, the periphery thereof contacts the peripheral edge 21 of the cut end face 16, so that both ends on the end side of the cap 4 are opened outward by leverage, so that the respective end side support recesses 15, 15 are formed. The pair of trailing-side claw pieces 19 that are engaged with the cap 4 are respectively pulled out outwardly to release the locked state, and the top portion of the cap 4 moves in the top direction, so that the cap 4 is locked in the top support groove 13. The upper claw piece 17 is pulled out upward, and a pair of sagittal claw pieces 18, 18 locked in the shoulder support recesses 14, 14 are drawn upward along the sagittal shape and locked. Release the state. The cap 4 is detached from the handrail main body 1 by releasing the locked state of the terminal-side claw piece 19, the top claw piece 17 and the sagittal claw piece 18. Thus, the removal of the cap 4 is completed by a single operation, and the handrail mounting device including the internal anchor screw 12 can be exposed.
Note that the top support concave groove 13 in the handrail main body 1 and the top claw piece 17 in the cap 4 may be omitted in some cases. As in this embodiment, the top support concave groove 13 and the top claw piece 17 are formed. Top claw piece 17 in concave groove 13
Is locked, the locked state can be further ensured.

FIG. 6 shows another embodiment according to the present invention. In this embodiment, a handrail is provided in an L-shape in parallel with the wall surface W, and a corner bracket 23 is fixed to a corner of the handrail, and the grip brackets of the handrail main bodies 1 and 1 are respectively attached to the corner bracket 23. One end of each of the parts 2 and 2 is attached. At each end of the handrail, that is, at each other end of the grip bar 2, the grip bar 2 and the bracket 3 are integrally formed, and the caps 4, 4 are fitted as in the above-described embodiment. It has a configuration and has the same operation and effect. The handrail main body 1 in which the bracket portion 3 is integrally formed only at one end of the gripping bar portion 2 is effective when an L-shaped handrail is formed.

[0015]

The present invention has the following effects. A. If the cap is fitted and covered mainly on the handrail after mounting on the wall, align the terminal edge of the cap with the edge of the mounting plate,
When the cap is directly pushed into the handrail main body side, the elasticity of the cap causes the sagittal claw piece and the terminal side claw piece of the cap to be locked in the handrail main body shoulder support concave part and the terminal side support concave part,
In a single operation, the cap is fitted and covered around the handrail. Since the cap is tightly fitted to the convex concave portion mainly composed of the handrail in a state of being fitted and covered, the inside does not flood, and the mounting device including the anchor present therein does not deteriorate. In addition, since the surface of the cap forms the same plane as the surface of the handrail main body, the user can grip the smooth handrail surface in which the gripping bar portion and the bracket portion are integrated without being aware of the presence of the cap. . The cap fitted and covered is maintained in a state of being fitted to the main handrail by utilizing its elasticity unless the capping cover is intentionally removed, so that the cap is not accidentally dropped.

B. When the fitted cap is intentionally removed, the central portion on the end side of the cap is pressed against the elasticity. Then, since the central portion on the end side keeps the non-contact state with the cut end face of the mounting plate portion, it moves to the cut end face side, and at the same time, its periphery contacts the peripheral edge of the cut end face, so that the lever acts. As a result, a pair of terminal side claw pieces locked in each terminal side support concave recess is pulled out outward by opening both sides of the cap terminal side outward, and the locked state is released, and the cap is closed. Since the top part moves in the top direction, a pair of sagittal claw pieces locked in each shoulder support cave pull out the shoulder support cave upward along the sagittal shape and the locked state To release. The cap is released from the main handrail by releasing the locked state of the terminal-side claw piece and the sagittal claw piece. In this manner, the removal of the cap is completed by a single operation, and the handrail mounting device including the internal anchoring tool can be exposed.

C. The handrail-based gripping bar and the bracket are formed integrally, and the mounting device to the building wall is built in so as not to be exposed to the outside. Since there is no connecting portion or mounting device to be exposed, it is possible to prevent the handrail components from being deteriorated due to water intrusion. In addition, since there is no connecting device between the gripping bar portion and the bracket portion or a mounting device for an exposed building wall surface, the user grips only a smooth surface without contacting a gap between parts or a mounting bracket. Therefore, the usability is improved. Furthermore, the appearance of the entire handrail is elegant with little mechanical resistance. D. A top support concave groove is formed at the top end of the convex concave fitting portion, a top claw piece is formed on the inner surface of the corresponding cap top end, and when the top claw piece is locked in the top support groove, the locking state is further ensured. can do. E. FIG. Since the handrail main body is integrally formed of a synthetic resin reinforced by mixing inorganic fibers, it is possible to easily manufacture a product having a sufficient proof stress. F. When the brackets are formed at both ends of the gripping bar, the entire handrail body including both the brackets is integrally manufactured, so that the handrail for a building that has good waterproofness and is mechanically strong is provided. Can be obtained at low cost. G. FIG. When the bracket portion is integrally formed at one end of the gripping bar portion, it is effective when forming an L-shaped handrail.
