Abstract

PROBLEM TO BE SOLVED: To lock a bar to prevent play in the axial direction. SOLUTION: In a bar support structure in which a mounting seat 2 is fixed on a wall face 7, a socket 3 is fitted in the bar 1, and inner periphery of the socket 3 is screw-fitted in outer periphery of the mounting seat 2 to support the bar 1, a screw is screwed in a position deviated from the center of an end face of the bar 1 to provide a projection 9, a groove 10 going toward the direction of center from the outer periphery is formed on the mounting seat 2, the projection 9 is engaged in this groove 10, and a protrusion amount of the projection 9 is adjusted in accordance with screwing-in of the screw so that the projection 9 abuts on an innermost part of the groove 10 at all times.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a structure for supporting a bar such as a handrail on a wall surface.

[0002]

2. Description of the Related Art For example, when a handrail is attached, as shown in FIG. 6, a bar 1 is supported on a wall 7 beside a window 6, so that as shown in FIG. 8, the socket 3 is fitted to the bar 1, and the female screw 5 on the inner periphery of the socket 3 is screwed to the male screw 4 on the outer periphery of the mounting seat 2 to be tightened.

[0003]

However, in the above-described support structure, when the bar is gripped, the bar may rotate, and the user may feel uneasy when leaning out of the window.

[0004] Further, since the bar is usually cut somewhat short, it may rattle in the axial direction, and it is desired to improve the stability when gripping the bar.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a rod for supporting a rod by fixing the mounting seat to a wall surface, fitting the socket to a bar, and screwing the inner periphery of the socket to the outer periphery of the mounting seat. In the support structure of the material, a screw or the like is screwed at a position shifted from the center of the end surface of the bar to form a projection, a groove is formed in the mounting seat from the outer periphery toward the center, and the protrusion is engaged with this groove, The axial movement of the bar is restricted by preventing the bar from rotating and adjusting the amount of protrusion of the protrusion so that the protrusion is always in contact with the depth of the groove.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, the same reference numerals are used for portions corresponding to the respective portions of the above-described conventional embodiment.

A first embodiment of the present invention is shown in FIGS. In this embodiment, a wooden bar 1 is used, and FIG.
As shown in FIG. 2, a screw is screwed into the bar 1 at a position deviated from the center of the end face thereof, and the projection of the screw 9
Is provided. The mounting seat 2 is formed with a groove 10 extending from the outer periphery toward the center, and the groove 10 has an abutment wall 11 at the back.

Then, the mounting seat 2 is fixed to the wall surface 7 with screws 8 with the groove 10 facing upward, and the socket 3 is fitted to the bar 1,
When the projection 9 is inserted into the groove 10 and engaged with it, and as shown in FIG. 3, the female screw 5 on the inner periphery of the socket 3 is screwed into the male screw 4 on the outer periphery of the mounting seat 2 and tightened. Stopped and supported.

At this time, the protrusion amount of the protrusion 9 is adjusted according to the screwing of the screw so that the protrusion 9
, The axial movement of the bar 1 is restricted and rattling is prevented.

Furthermore, when the center of the mounting seat 2 and the center of the socket 3 are aligned when the projection 9 reaches the lower end of the groove 10, when the socket 3 is screwed into the mounting seat 2,
There is no need to hold the bar 1 by hand.

Although the same effect as described above can be obtained by eliminating the abutting wall 11 and making the projection 9 directly contact the wall 7, the abutting wall 11 is provided as in this example. Thereby, the wall surface 7 can be protected from scratches caused by the contact of the projection 9.

Next, a second embodiment of the present invention is shown in FIG. In this embodiment, a pipe made of metal or plastic is used as the rod 1, and a wooden or plastic stopper 12 is packed in an end opening of the rod 1.
Is provided with a projection 9 into which a screw is screwed.

In the third embodiment shown in FIG. 5, a metal pipe is used as the rod 1, and an L-shaped fitting 13 is fixed to the inner surface of the end of the rod 1 by welding. This bracket 1
3 is provided with a projection 9 by screwing a screw.

Thus, even if the bar 1 is a pipe,
By using the stopper 12 and the metal fitting 13, the rod 1 can be prevented from rotating with the above-described structure, and the backlash in the axial direction can be prevented.

[0015]

As described above, in the bar supporting structure according to the present invention, the engagement between the groove of the mounting seat and the projection of the bar is performed.
The bar is prevented from rotating, the protrusion is adjusted, and the protrusion is always in contact with the back of the groove to regulate the axial movement of the bar, so the bar is firmly fixed to the wall can do.
