Abstract

PURPOSE: To fix a handrail easily onto a wall surface. CONSTITUTION: Handrail fixing structure consists of a handrail 1, in which both ends of a gripping pipe 2 are bent at right angles and a mounting pipe 3 is formed, a collar 6, in which a mounting hole is formed at the front end of the mounting pipe 3, and a cover 4, in which a female screw 5 is shaped to an inner circumferential surface in the mounting pipe 3. The handrail fixing structure is further composed of a fixing plate 8, in which a projecting section 11 is formed to one surface, mounting holes 9, 10 for fitting onto a wall surface (a) are formed to the projecting section 11 and the thickness of a peripheral section 22 is made approximately the same as the height of a bulging section, and a freely moving plate 14, in which a male screw 15 is shaped to an outer circumference and a window hole 16, into which the projecting section 11 is fitted movably, is formed at a center while a tapped hole is formed on the outside of the window hole 16. The projecting section 11 is fitted movably into the window hole 16 of the freely moving plate 14, the fixing plate 8 is fastened onto the wall surface by passing screws 16, 18 into the mounting holes, and the screw passed into the mounting hole of the collar 6 is screwed into the tapped hole of the freely moving plate 14, thus fixing a handrail onto the wall surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a handrail on a wall surface.

[0002]

2. Description of the Related Art Conventionally, when a mounting portion of a handrail is covered with a cover, a mounting plate having a male screw formed on the outer periphery thereof is fixed to a wall surface as disclosed in JP-A-63-168141. The cover is attached to the mounting plate by screwing to fix it, but it is difficult to mount the handrail unless the intervals between the mounting plates on both sides exactly match the length of the handrail. There is a drawback that it takes a long time to position.

[0003]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to easily attach a handrail whose mounting portion is covered with a cover to a wall surface.

[0004]

As a means for solving the above problems, the present invention provides a handrail in which both ends of a gripping pipe are bent at a right angle to form a mounting pipe, and a handrail fixed to the tip of the mounting pipe and symmetrical. A collar having a bulged portion formed at a position and a mounting hole formed in each bulged portion, a cover loosely fitted to the mounting pipe and having an internal thread formed on an inner peripheral surface, and a protrusion formed on one surface. Has a notch portion into which the bulging portion of the collar is fitted, and the thickness of the peripheral portion is equal to the height of the bulging portion. A fixing plate that is slightly larger than this, a male screw is formed on the outer periphery, a window hole is formed in the center where the protrusion is loosely fitted, a screw hole is formed outside the window hole, and the thickness is the protrusion. A floating plate that is smaller than the height of the portion, and the protrusion is loosely inserted into the window hole of the floating plate. Then, the fixing plate is fixed to the wall surface by passing the screw through the mounting hole, and the screw passed through the mounting hole of the collar is screwed into the screw hole of the floating plate to fix the handrail to the wall surface. At the same time, the female screw of the cover is screwed onto the male screw of the floating plate to move the floating plate,
The fixing plate and the flange are covered with the cover.

[0005]

According to the present invention having the above-mentioned structure, the window hole of the floating plate is loosely fitted in the projection of the fixed plate, and the thickness of the floating plate is smaller than the height of the projection of the fixed plate. The floating plate floats when the plate is fixed to the wall surface. Therefore, even if there is some error in the fixing position of the fixing plate, the flange of the mounting pipe can be attached to the floating plate, and at that time the fixing plate is tightened with the floating plate and the flange, so the handrail is firmly fixed to the wall surface. In addition, the cover can be aligned with the floating plate and screwed, and the handrail whose mounting portion is covered with the cover can be easily mounted on the wall surface.

Further, the bulging portion of the brim is fitted into the notch of the fixing plate, and the thickness of the peripheral portion of the fixing plate is the same as or slightly larger than the height of the bulging portion, so that the bulging portion contacts the floating plate or Since the handrails are close to each other, the handrail does not tilt when tightening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a handrail in which both ends of a gripping tube 2 are bent at a right angle to form a mounting tube 3, and the mounting tube 3 is provided with a cover 4 having a female screw 5 formed on the inner periphery of the lower end thereof. It is loosely fitted, and a collar 6 is fixed to the lower end of the mounting tube 3, and bulging portions 21 are formed at symmetrical positions on both sides thereof, and a mounting hole 7 is formed in the bulging portion 21.

Reference numeral 8 denotes a downwardly projecting portion 11 formed at the center of the peripheral edge portions 22 on both sides, and two mounting holes 9 with a seat and a mounting hole 10 without a seat are formed, and a collar is provided between the peripheral edge portions 22 on both sides. 6 is a fixing plate in which a cutout portion 20 into which the bulging portion 21 of 6 is fitted is formed, and the thickness of the peripheral edge portion 22 is the same as or slightly larger than the height of the bulging portion 21 of the collar 6.

Reference numeral 14 is a floating plate having a male screw 15 formed on the outer periphery thereof, an oval window hole 16 larger than the protrusion 11 formed in the center thereof, and screw holes 17 formed on both sides thereof. The thickness is smaller than the height of the protrusion 11.

Next, the assembling order of this embodiment will be described. First, the projection 11 of the fixed plate 8 is connected to the window hole 16 of the floating plate 14.
As shown in FIG. 1, when the screw 18 is inserted into the mounting hole 9 of the fixing plate 8 and screwed into the wall surface a, the fixing plate 8 is fixed to the wall surface a and the floating plate 14 is fixed to the wall surface a. It is movably supported between the peripheral portions 22 of the plate 8.

When the implant bolt 16 is implanted on the wall surface a, the bolt 16 is passed through the mounting hole 10 of the fixing plate 8 and fixed by the nut 23.

Next, the collar 6 is applied to the peripheral edge portion 22 of the fixed plate 8, and the screw 19 passed through the mounting hole 7 is screwed into the screw hole 1 of the floating plate 14.
Screw in 7. At this time, as shown in FIG.
Since the window hole 16 of No. 4 is loosely fitted in the protrusion 11 of the fixed plate 8 and the floating plate 14 is free to move freely with respect to the fixed plate 8, there is some error in the mounting position of the fixed plate 8. Even
The mounting hole 7 of the collar 6 can be aligned with the screw hole 17 of the floating plate 14, and when the screw 19 is tightened, the thickness of the peripheral edge portion 22 of the fixing plate 8 is the same as or slightly larger than the height of the protruding portion 21, As shown in FIG. 1, the peripheral edge portion 22 of the fixing plate 8 is the collar 6
The handrail 1 is sandwiched between the movable plate 14 and the floating plate 14.
Is fixed to the wall surface a.

Then, the female screw 5 of the cover 4 is attached to the floating plate 14.
As shown in FIGS. 1 and 2, when the male screw 15 of FIG.
The collar 6, the fixed plate 8 and the floating plate 14 are covered with the cover 4 to improve the appearance.

As described above, the peripheral edge portion 22 of the fixed plate 8 is
Since the thickness of the handrail is the same as or slightly larger than the height of the protrusion 21, when the screw 19 is tightened from one side, the handrail 1
There is no risk of tilting.
