Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a hanger used for, for example, a towel rack installed on the wall of a washroom.

[Conventional technology]

BACKGROUND ART Conventionally, hangers such as towel racks have been used that include a support fitting for fixing to a wall surface and a hanging bar connected to the support fitting and arranged in a substantially horizontal position. The most common structure for fixing the supporting metal to the wall is to provide the supporting metal with a flange with a screw hole, and to fix the supporting metal by screwing a screw that passes through the screw hole into the wall.

On the other hand, when fixing this support bracket with screws, in addition to the disadvantage of the appearance of the screw heads being exposed, if the screws are not screwed in enough or become loose, it is difficult to pull the towel. It is often hung.
In response to this problem, a structure in which the supporting metal fittings are covered with a cover has recently been adopted.

This is equipped with a fixing member that is fixed to the wall surface with screws, and a cylindrical cover that is screwed onto the outer periphery of this fixing member, so that the cover covers the fixing member and the screws. ing.

[Problem that the invention attempts to solve]

By the way, the design condition is that the outer shape of the fixing member is cylindrical in order to connect the cover with a screw. Therefore, in order to enable the fixing member to be fixed to a wall surface with screws, it must be shaped like a cylinder with a bottom having a screw hole at one end.

In the case of such a shape of the fixing member, the fixing member is attached to the wall surface by first fixing the fixing member to the wall surface with screws, and then screwing the cover into the fixing member. However, when screwing the cover in, if the rotation axis of the cover coincides with the rotation center of the screw, co-circulation will occur. In other words, when the cover is tightened to a certain degree, the screw connection force between the cover and the fixing member increases, so if the center of rotation of the cover and the screw supporting the fixing member are coaxial, it will not be possible to fix the cover when installing it. The member is rotated with this cover.

Therefore, it becomes difficult to remove the cover.
Further, if the fixing member has directionality, there is a problem that it cannot be installed in a normal position.

Therefore, the purpose of the present invention is to prevent co-circulation when screwing a cover into a fixing member that is attached to a wall surface using screws, and to enable the support bracket to be fixed in the correct position and posture with respect to the wall surface. .

[Means for solving problems]

In order to achieve the above objectives, the hanger of the present invention includes a bottomed cylindrical fixing member that is fixed to a wall surface with screws, and a female thread that is screwed into a male thread carved on the outer periphery of the fixing member. on the inner periphery and is integrated with the fixing member by restraining the proximal end of the main frame of the hanger to the fixing member, and the screw hole through which the screw is inserted is aligned with the axis of the fixing member. It is characterized in that it is opened at the bottom of the fixing member eccentrically from the center.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 is a partially cutaway plan view of a hanger showing an embodiment of the present invention.

The hanger is composed of a substantially U-shaped main frame 1 and a plurality of hanging bars 2 fixed to the main frame 1, and two base ends of the main frame 1 are fixed to a wall surface A.

FIG. 2 is an enlarged sectional view showing the fixing structure between the main frame 1 and the wall surface A, and FIG. 3 is an exploded perspective view showing the main parts.

A bottomed cylindrical fixing member 4 is fixed to the wall surface A by screws 3, and the fixing member 4 covers the fixing member 4 and at the same time restrains and holds the base end of the main frame 1 on the fixing member 4 side. Cover 5 is screwed in.

The fixing member 4 has a cylindrical shape with a bottom as described above,
A male screw 6 is carved on the peripheral surface of one end, and a hollow portion 7 into which the base end of the main frame 1 is inserted is provided.
is formed. Further, a screw hole 9 into which the screw 3 is inserted is provided in the bottom portion 8 on the side where the male screw 6 is formed. As shown in FIG. 4, this screw hole 9 is provided at a position eccentric to the axis of the fixing member 4, and the position of the screw hole 9 does not coincide with the center of the male screw 6.

The cover 5 is a substantially hollow cylindrical body made of a thin material, and has a male screw 6 of the fixing member 4 on the inner periphery of one end.
A female thread 10 is formed to be screwed into the. Further, an annular collar portion 11 is provided at the other end to cover the end surface of the fixing member 4.

Furthermore, a concave groove 12 is formed on the circumferential surface of the base end of the main frame 1.
A fixing ring 13 is fitted into this groove 12. As shown in FIG.
The main frame 1 is connected to the fixing member 4 by being restrained by the flange 11 of the cover. In addition, hanging bar 2
is the mounting hole 14 opened on the opposite surface of the main frame 1.
is inserted, and its both ends are held and fixed by buffer bodies 15 provided within the main frame 1. This buffer 15 is made of an elastic body such as rubber, and is made of an elastic material such as rubber.
Both ends are elastically restrained and fixed, and rattling and noise are prevented from occurring.

In the hanger having the above components, after the fixing member 4 is fixed to the wall surface A with the screws 3, the main frame 1 and the cover 5 are connected to the fixing member 4. In this case, the main frame 1 is inserted into the cover 5 so that the ring 13 is located on the inner surface of the flange 11, and in this state, the female screw 10 of the cover 5 is screwed into the male screw 6 of the fixing member 4.

When integrating this cover 5, the male screw 6
The screw connection force generated by the female screw 10 attempts to rotate the fixing member 4 fixed to the wall surface A by the screw 3. However, since the screw hole 9 is eccentric with respect to the axis of the fixing member 4, it is also in an eccentric relationship with the male thread 6 on the circumferential surface, and the rotational force when screwing the cover 5 rotates the fixing point of the fixing member 4. It is not possible to generate the acting force that causes That is, even if the cover 5 is rotated, the screws 3 are fixed to the wall surface at a position away from the center of rotation of the fixing member 4, so the screws 3 are fixed in the circumferential direction around the axis of the fixing member 4. It only receives the power of. As a result, the rotational force around the core of the screw 3 does not act, and even if the cover 5 is firmly fastened, the fixing member 4 does not rotate together and remains at a predetermined position.

Therefore, since the fixing member 4 is held in a fixed position by the screws 3, it can be attached without digging into the wall surface A or rotating, resulting in insufficient connection of the cover 5. Moreover, even if the outer shape of the fixing member 4 has directionality,
Since the posture can always be maintained fixed to the wall surface A, the hanger can be reliably attached to a predetermined position.

[Effect of idea]

As explained above, in the hanger of the present invention, the screw holes of the fixing member attached to the wall surface with screws are arranged eccentrically, and the rotational force of the cover screwed onto the circumferential surface of the fixing member is applied to the center of the fixing member. I try not to burden those around me. Therefore, the cover can be attached without the fixing members rotating together, which simplifies the construction work. Furthermore, since the fixing member does not dig into the wall or change its posture, it is possible to adjust the level with the wall surface as set, making it possible to install the hanger accurately.
