Abstract

PROBLEM TO BE SOLVED: To enable easy execution of fixing work from one side even in a place where an obstacle is present on the other side, by a simple structure. SOLUTION: A handrail fitting implement 1 has a structure wherein an arm part 4 is provided obliquely from one side of a pedestal 2 and a support part 3 is provided at the fore end thereof. In the pedestal 2, two slant fitting holes 5 are provided in one side part wherein the arm part 4 is provided, while a vertical fitting hole 6 is provided in the other side part. The pedestal 2 is provided with marks 9 indicating the center in the opposite ends in the longitudinal direction. The fitting holes 5 and the fitting hole 6 are so provided that all extensions of the axes thereof to the surface side exist in bias to one side of the support part 3, while the points where the extensions of the axes to the rear side intersect a fitting surface K exist on the opposite sides of the center line C of the rear of the pedestal which is parallel to the lengthwise direction of fitting of a handrail material. The support part 3 is provided with holes 7 for fixing the handrail material T and with marks 8 indicating the center in the opposite ends in the lengthwise direction in the same way as the pedestal 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail mounting device for mounting a handrail to a mounting surface such as an upper surface or a wall surface of a stair railing wall, which can be easily and firmly fixed to the mounting surface. This is an improvement.

[0002]

2. Description of the Related Art Conventionally, as in the invention of Japanese Patent Application Laid-Open No. 7-197619, an arm is erected at the center of a pedestal, a receiving portion is provided at an upper end thereof, and a mounting hole is provided in the pedestal. The mounting hole is such that an extension of its axis is present on both sides of the receiving portion.

[0003]

In the above conventional example, the screws inserted into the mounting holes must be tightened from both sides of the receiving portion. For example, the mounting location is the upper surface of the handrail wall and the rear side is the wall. If there is an obstacle on one side, such as when it is turned off, only one of the mounting holes can be fixed, even if it can be done, it requires a special tool, making it difficult to work, and obstacles (walls etc.) ).

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a handrail mounting tool having a pedestal fixed to a mounting surface and a receiving portion for mounting a handrail material.
A plurality of mounting holes through which screws are inserted are provided, at least some of the mounting holes are inclined with respect to the axis, and the extension of the axis of all the mounting holes to the surface side is biased toward one side of the receiving portion,
The point where the extension line of the axis of the mounting hole to the back surface side intersects the mounting surface exists on both sides of the center line on the back surface of the pedestal, which is parallel to the mounting longitudinal direction of the handrail material.

[0005]

According to the present invention, the work of tightening and loosening the screw can be all performed from one side of the receiving portion, and after fixing, the screw is parallel to the longitudinal direction of the mounting of the handrail material. It protrudes on both sides of the center line on the back of the pedestal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A handrail attachment 1 is provided with an arm 4 at an angle from one side of a pedestal 2 (an angle formed with the pedestal 2 is an acute angle), and a receiving portion 3 having an arc-shaped cross section at its tip. The pedestal 2 is provided on one side where the arm 4 is provided with two mounting holes 5.5 whose axes are inclined in the same direction as the arm 4, and the pedestal 2 is provided on the other side.
Is provided with a vertical mounting hole 6. Further, the pedestal 2 is provided with marks 9 indicating the center at both ends in the longitudinal direction (the direction in which the handrail material T described later extends). In the mounting holes 5, 5 and the mounting holes 6, the extension lines extending to the front surface side of the axis are all present on one side of the receiving portion 3, and the extension lines extending to the back surface side of the axis are the mounting surface K. 11 are the center lines C (marks 9 and 9) on the back of the pedestal, which are parallel to the longitudinal direction of the handrail material.
9). The receiving portion 3 is provided with holes 7.7 for fixing the handrail material T, and similarly to the pedestal 2, marks 8.8 indicating the center are provided at both ends in the longitudinal direction.

[0007] To attach the handrail material T to the handrail material T
.. Are attached by inserting screws from the holes 7 at intervals, and this handrail mounting tool 1... 1 is attached to the mounting surface K such as the upper surface of the handrail wall. Screw 1 from mounting hole 6
0 ... 10 are inserted and fixed. At this time, in order to install the handrail straight, the marks 8.8 are aligned with the straight line drawn on the handrail material T, and the marks 9.9 are aligned with the straight line drawn on the mounting surface K such as the upper surface of the handrail wall.

As shown in FIG. 3, even when the mounting surface K is the upper surface of the handrail wall and the back side is a wall, an ordinary driver D is inserted from one side opposite to the wall into the mounting holes 5.5 and 5. 6
10 can be engaged and tightened. Then, after tightening and fixing, the screws 10... 10 protrude from the rear surfaces of the mounting holes 5 and 6 and both sides of the center line C on the rear surface of the pedestal, which is parallel to the mounting longitudinal direction of the handrail material T. Are screwed into the mounting surface K, and there is no deviation in how the screws 10... 10 work.

[0009]

As described above, according to the present invention, even with a simple structure, even if there is an obstacle on one side, the fixing operation can be easily performed from the other side without damaging the obstacle, and Has an effect that a firm fixing state can be obtained without bias in the effect of the screw.
