DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fixing structure for fixing a handrail to a wall surface.

[0002]

2. Description of the Related Art Conventionally, to fix a handrail to a wall surface, as disclosed in JP-A-63-168141,
A disk with an external thread formed on the outer circumference is fixed to the wall with bolts,
A cap having an internal thread formed on an inner periphery is fitted to a mounting portion of a handrail, and the cap is screwed to a disk.

[0003] However, in such a method, it is necessary to fix bolts for fixing the disk to the wall surface at an accurate interval according to the length of the handrail, and the mounting operation is difficult.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily attach a handrail to a wall surface even if there is a slight error in the installation interval of a resin plug for screwing a bolt or a screw. It is to be.

[0005]

Means for Solving the Problems, Functions and Effects As means for solving the above-mentioned problems, the invention of claim 1 is an invention for attaching a handrail to a handrail made of a pipe material having attachment portions bent at both ends of a gripping portion. At one end of the mounting plate, an elongated mounting plate is fixed at one end in the longitudinal direction, and at the other end of the mounting plate, an elongated hole is formed in the mounting plate in the longitudinal direction, and a bolt is passed through the elongated hole. Alternatively, since the mounting plate is fixed to the wall surface with screws, the handrail can be easily fixed to the wall surface even if there is some error in the mounting interval of the bolt or the resin plug.

According to a second aspect of the present invention, in the first aspect of the present invention, the mounting plate is fixed to an end of the mounting portion by welding so that a length direction of the mounting plate extends in a direction in which the grip portion extends. .

According to a third aspect of the present invention, in the first aspect, a fixing plate is fixed to an end of the mounting portion, a screw hole is formed in the fixing plate, and the mounting plate is formed in the mounting plate. The screw passed through the screw hole is screwed into the screw hole and fixed to the mounting part, so not only the error in the long hole direction but also the error in the circumferential direction around the through hole is absorbed by loosening and rotating the screw can do.

[0010] According to a fourth aspect of the present invention, in the third aspect of the present invention, the periphery of the through hole of the mounting plate is recessed so that the head of the screw sinks, so that the mounting plate is brought into close contact with the wall surface. Thus, the handrail can be stably fixed to the wall surface.

The invention according to claim 5 is based on claim 1, claim 2,
According to the third or fourth aspect of the present invention, since the mounting plate is covered with the cap, the appearance is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

In the drawing, reference numeral 1 denotes a handrail made of a pipe material in which a mounting portion 3 is bent at both ends of a straight grip portion 2, and a fixing plate 4 is welded at a position slightly entering from the end of the mounting portion 3. And a screw hole 5 is formed at the center.

Reference numeral 6 denotes an elliptical mounting plate, which is stamped on one side to the upper surface side to form a through hole 7 and a conical concave portion 8, and the other side has an elongated hole 9 elongated toward the through hole 7. Are formed.

Reference numeral 10 denotes a countersunk screw, 11 denotes a cap made of synthetic resin, and 13 denotes a packing made of a soft synthetic resin sheet.

In order to attach the handrail 1 to the wall surface a, the cap 11 is lifted up to the vicinity of the grip portion 2 and the countersunk screw 10 passed through the through hole 7 is screwed into the screw hole 5 of the fixing plate 4 to attach the handrail 1 to the mounting plate. 6 is fixed to the handrail 2. At this time, the head of the countersunk screw 10 fits into the recess 8 so as not to protrude from the lower surface of the mounting plate 6.

Next, a packing 13 is applied to the lower surface of the mounting plate 6, a bolt 15 passing through the elongated hole 9 is inserted into the mounting hole b penetrating the wall surface a, and the bolt is fastened and fixed with a nut 14, so that the cap 11 is fixed. The claw 12 formed on the inner periphery is hooked on the mounting plate 6 and fitted tightly.

When the wall a is made of concrete, bolts may be implanted in advance.

In this embodiment, since the elongated hole 9 is elongated in the direction of the through hole 7, the screw 10 can be loosened and turned to fix the mounting hole b in any direction. .

Further, in the present embodiment, since the packing 13 is interposed between the mounting plate 6 and the wall surface a, it is possible to prevent water from entering even in a portion where water is applied, such as a bath wall.

The mounting plate 6 may be fixed in any direction as shown by a chain line in FIG.

Next, another embodiment of the present invention will be described with reference to FIGS.

Referring to FIG. 1, reference numeral 1 denotes a handrail made of a pipe material having an attachment portion 3 bent at an end of a grip portion 2 and has a long hole 9 formed at one end in a length direction thereof. The mounting portion 3 is fixed to the other end of the mounting plate 6 by welding 20 with its length direction facing the extension direction of the grip portion 2.

Reference numeral 21 denotes a synthetic resin cap comprising a main body 22 having an opening 24 narrower than the outer diameter of the handrail 1 and a small piece 23 for closing the opening 24.
Is pressed against the handrail 1 from the radial direction and is fitted to the handrail 1 by elastic deformation, and the small pieces 23 are hooked at both ends thereof.
26 formed between projecting pieces provided on both sides of the opening 24
It is integrated with the main body 22 by fitting, and the mounting plate 6 is applied to the wall surface a with the packing 13 slightly smaller than this,
A female screw is cut on the inner periphery of the screw 30 that has been
Screwed into the resin plug 31 fitted in the
When the cap 21 is pressed against the mounting plate 6 after being fixed to the mounting plate 6, the cap 21 expands and contracts due to elastic deformation, so that the mounting plate 6 is sandwiched between the projections 27 and 28.
1 is fixed to the mounting plate 6.

At this time, the connection between the main body 22 of the cap 21 and the small piece 23 is hidden under the grip 2 of the handrail 1, so that the appearance is not impaired.
