[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a structure for fixing ashtrays, soap holders, accessory stands, towel hangers, and other accessory devices (hereinafter simply referred to as "devices") to walls of buildings, etc.

[Prior art]

FIG. 3 is a side sectional view showing a situation in which a ceramic fixture 2 (also a table for small items) is fixed to the wall 1, and FIG. ) is a side cross-sectional view showing a situation in which it is fixed to a wall surface 1. As shown in FIG. 3, in order to fix the ceramic fixture 2 to the wall surface 1, the L
A connecting member 3 having a letter shape is fixed, an instrument 2 is fitted into the connecting member 3 from the front side thereof, and a screw 4 is screwed into the instrument 2 from the lower surface side to connect the two. The instrument 2 has a hollow interior and is open at its back surface. Therefore, the connecting member 3 is housed within the cavity of the instrument 2 and is not visible from the outside. On the other hand, as shown in FIG. 4, in order to fix the metal fixture 5 to the wall surface 1, a connecting member 6 shaped like an upright plate was used. That is, the connecting member 6
is formed such that the distance between its upper and lower surfaces becomes smaller as it approaches the wall surface 1. Therefore, when the instrument 5 is fitted into the front side of the connecting member 6, the upper inclined surface 6a of the connecting member 6 is engaged with the inclined surface provided inside the back surface of the instrument 5, and the instrument 5 is attached to the wall surface 1. You will be drawn to. Also, in this state, the instrument 5
When the fixing screw 7 is screwed into the lower surface of the
Since a reaction force is produced on the instrument 5 by pushing up the lower inclined surface 6b in the vertical direction, the instrument 5 is drawn toward the wall surface 1, and the above-mentioned action is further enhanced.

[Problem to be Solved by the Invention] In the ceramic device 2 (see FIG. 3), there is usually some shrinkage error in its external dimensions. This shrinkage error is caused by the connection member 3 and the instrument 2.
When connecting the two, this appears as misalignment between the through hole for the screw 4 and the female screw hole. Therefore,
As shown in FIG. 3, when fixing the connecting member 3 to the wall surface 1, it was often necessary to provide a plate-shaped spacer 8. If the thickness of the spacer 8 is inappropriate or if the spacer 8 is not provided properly, the instrument 2 will not be able to be firmly fixed. Furthermore, the work of intervening Space-8 was extremely troublesome. On the other hand, in the case of the metal instrument 5 (see Fig. 4), although the connection with the connecting member 6 is strong, the fixing screw 7 protrudes from the lower surface of the instrument.
It was inferior in appearance. Furthermore, during cleaning, a rag could get caught on the protruding part of the fixing screw 7, causing breakage or injury. The present invention was developed in view of the above-mentioned circumstances, and is a novel fixing structure (hereinafter referred to as " Structure of the case
The purpose is to provide

[Means to solve the problem]

The gist of the proposed structure is that a structure for fixing an accessory device to a wall surface includes a connecting member fixed to the wall surface, and the accessory device having a storage recess for the connecting member on the back side; The connecting member has a hook portion extending from one end of the fixed piece portion fixed to the wall surface, and a connecting piece portion facing the fixed piece portion extending from the hook portion,
Further, a boss portion is formed by bending from the free end of the connecting piece, a lowering bolt eccentric from the connecting piece is screwed into the boss portion, and the inner surface of the housing recess for the accessory device is screwed into the boss portion. A hook portion that engages with the hook portion of the connecting member is formed in the portion, and a tool insertion hole having a smaller diameter than the tool engaging portion is formed in the inner surface portion corresponding to the tool engaging portion formed in the lowering bolt. It is located at the point where it is drilled.

[Effect]

A reduction bolt is previously screwed into the boss portion of the connecting member that is already fixed to the wall surface. It is preferable that the lowering bolt be fully screwed so that the tool engaging portion approaches the boss portion of the connecting member. An instrument is fitted into the connecting member in this state from the front side, and the hooks are engaged with each other. Next, a tool such as a screwdriver is inserted through the tool insertion hole drilled in the instrument, and the lowering bolt screwed into the boss portion of the connecting member is turned back. Therefore, the reduction bolt is
Strongly press the inner surface of the storage recess in the instrument (the periphery of the opening of the tool insertion hole) toward the outside. This pressing force strengthens the state of engagement between the hook portion of the connecting member and the hook portion of the instrument, as described above, so that the instrument is firmly fixed to the wall surface. Even if the reduction bolt is turned too much and the pressing force suddenly increases, since the reduction bolt is eccentric to the connecting piece, a bending moment will be generated on the free end side of the connecting piece, causing the connecting piece to flex. This prevents the device from rising rapidly and prevents damage or deformation of the device.

【Example】

The present invention will be described below based on drawings showing embodiments thereof. FIG. 1 is a side sectional view showing the proposed structure. The proposed structure is characterized by the connection structure between the instrument 18 and the connecting member 16. The connecting member 16 is formed by bending a metal plate. That is, the connecting member 16 connects the wall surface 1
A hook portion 16a that slopes diagonally upward toward the front extends from the upper end of the fixed piece portion 16c that is fixed by an anchor material 13 such as a nail or bolt, and a connecting piece that faces the fixed piece portion 16c. Part 16d
extends from the hook portion 16a. Further, in the connecting member 16, a boss portion 16b is formed by bending from the free lower end of the connecting piece portion 16d. The boss portion 16
In b, a female threaded portion 16e is formed by burring (a process in which a burr is intentionally left around the hole by press molding and a female screw is carved into the inner surface of the burr). The boss portion 16b of the connecting member 16 has the connecting piece portion 1
A lowering bolt 10 eccentrically E than 6d is screwed. The lowering bolt 10 is configured such that a tool engaging portion 10a such as a driver groove faces downward.
The reduction bolt 10 is arranged so that its line of action approaches the portion where the hook portions 15b and 16a engage with each other. Therefore, the connecting member 16 and the instrument 1
5, the force transmission efficiency is improved, and this joining operation also improves the connection member 1 to the wall surface 1.
There is no fear that the fixed state of No. 6 will be threatened. The device 15 is made of ceramic or resin, and has a storage recess 19 in which the connection member 16 can be stored on the back side thereof. The storage recess 1
9 is formed with a short hanging wall along the back side of the instrument 15, which hanging wall forms a hook portion 15b that engages with the hook portion 16a of the connecting member 16. Further, a tool insertion hole 15a is bored in the lower inner surface 19a of the storage recess 19 at a position corresponding to the tool engagement portion 10a of the lowering bolt 10 screwed into the connecting member 16. . The tool insertion hole 15a has a hole diameter smaller than the diameter of the head 10b of the reduction bolt 10. In this embodiment, since the instrument 15 is a holder for roll paper or the like, as shown in a perspective view in FIG. 2, in the connecting member 16, hook portions 16a, 16
a and boss portions 16b, 16b are provided. In addition, the device 15 has storage recesses 19 formed on the back surfaces of the left and right boulder portions 18, 18 (see FIG. 1) that sandwich and hold the roll paper. The reduction bolt 10 uses a round screw, and due to the pressing force of the reduction bolt 10, the tool 15
If there is a risk of damage (if made of ceramic or resin) or deformation (if made of metal), make the reduction bolt 10 made of resin, or insert a flanged bushing into the tool insertion hole 15a of the device 15. All you have to do is take measures such as keeping it in place. In the proposed structure constructed in this way, first, the connecting member 16 is fixed to the wall surface 1 with the anchor material 13. At this time, it is preferable that the lowering bolt 10 screwed into the boss portion 16b of the connecting member 16 be fully screwed in so that the head portion 10b comes into contact with the back surface of the boss portion 16b. Next, the instrument 15 is fitted into the connecting member 16 and the lowering bolt 10 from the front side thereof. When the instrument 15 is slightly pulled down along the front of the wall surface 1, the hook portion 16a of the connecting member 16 and the instrument 15
Since the hook portion 15b is engaged, the instrument 15 is held against the wall surface 1. And equipment 1
A tool such as a screwdriver (not shown) is inserted into the tool insertion hole 15a formed in the lower surface of the connecting member 5, and the lowering bolt 10 screwed into the connecting member 16 is turned back. The head 10b of the lowering bolt 10 will eventually reach the lower inner surface 19a of the storage recess 19 in the instrument 15.
(the opening periphery of the tool insertion hole 15a) and further presses the instrument 15 downward. Therefore, the instrument 15 is pressed downward along the front of the wall surface 1, and the state of engagement by the hook portions 15b and 16a is strengthened. Even if the lowering bolt 10 is turned too much and the pressing force is about to rise rapidly, since the lowering bolt 10 is eccentric with respect to the connecting piece 16d, a bending moment is generated at the free lower end of the connecting piece 16d, causing the connecting piece to Since the portion 16d is bent, it is prevented from rising rapidly, and the instrument 15 is not damaged or deformed.

[Effect of the idea]

As detailed above, the present invention has the following practical effects. Since the connecting member and the instrument are not connected by inserting screws or the like between them, even if there is a shrinkage error in the external dimensions of the ceramic instrument, there will be no adverse effects due to misalignment. Therefore, there is no need for spacers, etc., which were required in the past. There are no screws protruding from the bottom of the device, so there is no chance of it breaking or causing injury if a rag gets caught on it. The reduction bolt that connects the connecting member and the instrument is
Since the bolt is screwed onto the connecting member in advance, there is no risk of the lowering bolt falling during the joining operation. Even if the pressing force is to suddenly increase due to excessive rotation of the reduction bolt, a suitable degree of deflection occurs in the connecting piece, preventing the sudden increase. Therefore,
It will not cause damage or deformation to the equipment.
