[Technical issues]

The technical problem of the present invention is to attach the interior bar to the mounting wall from inside the room without exposing the screws inside the room.

[Means for achieving technical challenges]

The technical means taken to achieve the above technical problem includes an interior bar and a wall mounting body, and the wall mounting body is attached to a wall mounting flange having a recess in the center and a wall mounting flange having a recess in the center. It consists of a mounting screw whose head is fitted and whose screw shaft protrudes from its flange, and a cushion material which accommodates the wall mounting flange in a fitted manner and has a locking protrusion integrally molded on the outer circumferential surface. , Screw the threaded portion of the mounting screw into the screw hole drilled in the end of the interior bar, and attach and fix the wall mounting flange to the mounting wall, and loosely fit on the interior bar and be locked to the inner circumferential surface. The engaged protrusion of the flange cap having a protrusion is removably engaged with the engagement protrusion of the cushion material.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

In the figure, A indicates the sidemost end of the prefabricated interior bar, that is, the interior bar corresponding to an architectural wall or other mounting wall C, and this interior bar A is attached to the mounting wall C via a mounting device.

This interior bar A is integrally molded from thermoplastic resin such as ABS or nylon, and has a recess A ₂ at one end, that is, a portion corresponding to the mounting wall C, and a screw hole A communicating with the recess A ₂ . ₁ is opened, and the connection part of the adjacent interior bar A' is formed at the other end.

This interior bar A is attached to a mounting wall C by a wall mounting body B and a flange cap D.

The wall mounting body B includes a wall mounting flange b 1 having a recess b ₁ -1 in the center and screw holes b _{1 -2} formed at intervals around the recess b 1 _-1 , and the recess b ₁ −
The head b ₂ -1 is accommodated in the fitted state in the screw shaft part b ₂ -
2 to its concave part b ₁ -1 Mounting screw that protrudes from the bottom
b ₂ and a cushion material b ₃ which has a locking protrusion b ₃ -1 integrally formed on the outer circumferential surface in which the wall mounting flange b ₁ is fitted.

The cushion member b ₃ is integrally molded from an elastic material, has a saucer shape with a depth sufficient to fit the wall mounting flange b ₁ , and has a portion facing the recess b ₁ -1. At the same time, a cylindrical portion b _{3 -2 that fits into the screw hole b 1} -2 is integrally formed in a protruding portion at a portion facing the screw hole b _{1 -2} , and a locking protrusion b ₃ is formed on the outer peripheral surface. -1 is integrally provided.

The flange cap D is loosely fitted onto the interior bar A, and has a locking protrusion _d1 on its inner peripheral surface that elastically engages with the locking protrusion _b3-1 .

To explain the case of installing the interior bar A on the mounting wall C using such a mounting device step by step, the cushion material b is inserted so that the cylindrical portion _b3-2 enters the screw hole _b1-2 . Fit the wall mounting flange b ₁ into the wall mounting flange b ₁ and attach _{the cushion material b 3 to} the wall mounting flange b 1. In this state, the head of mounting screw _B2
b ₂ -1 is fitted into the recess b ₁ -1 and the screw shaft portion is inserted.
b ₂ -2 screw hole drilled in interior bar A ₁
Attach wall mount B to interior bar A by screwing it together. Thereafter, the interior bar A is fixed to the mounting wall C by fixing the screws 1 inserted through the screw holes b ₁ -2 of the wall mounting body B flange b ₁ to the mounting wall C. Finally, the locking protrusion _d1 on the inner peripheral surface is engaged with the locking protrusion _b3-1 , and the screw 1 is covered with the flange cap D.

In addition, the connection part has a screw shaft e ₁ at both ends as shown in Figure 1.
A housing space 200 large enough to accommodate one half of the connecting fitting E protruding from the housing space 200;
It consists of a screw hole 201 opened in communication with the
With one half of the connecting fitting E housed in the housing space 200, one screw shaft _e1 is screwed into the screw hole 201 to connect it to the adjacent interior bar A'.
This adjacent interior bar A' covers the outer periphery of the metal tube _A1 with a plastic sheathing material _A2 , and connects a bushing _A3 having a screw hole 201 at the end with a connecting fitting E between the end face of the plastic sheathing material _A2 . The accommodation space 200 that accommodates the other half is fitted and fixed slightly inward so as to hold the accommodation space 200.
0 accommodates the other half of the connection fitting E and screw hole 2
By screwing the other screw shaft _e1 into the mounting wall C, the interior bar A fixed to the mounting wall C is connected to the mounting wall C.

[Function and effect of the idea]

As described above, the present invention includes an interior bar and a wall mounting body, and the wall mounting body is connected to a wall mounting flange having a recessed portion in the center, and a screw shaft having a head fitted into the recessed portion. The threaded shaft portion of the mounting screw is composed of a mounting screw having a portion protruding from its flange, and a cushion material that accommodates the wall mounting flange in a fitted manner and has a locking protrusion integrally molded on the outer circumferential surface. is screwed into the screw hole drilled at the end of the interior bar, and the wall mounting flange is attached and fixed to the mounting wall, and the flange cap is loosely fitted to the interior bar and has a locking protrusion on the inner peripheral surface. Since the locked protrusion is removably engaged with the locking protrusion of the cushion material, the following effects can be achieved. The wall mounting flange is fitted into the cushion material so that the cylindrical portion enters the screw hole, and the cushion material is attached to the wall mounting flange. In this state, the head of the mounting screw is fitted into the recess, and the screw shaft portion is screwed into the screw hole formed in the interior bar to attach the wall mounting body to the interior bar. Thereafter, the interior bar is fixed to the mounting wall by fixing to the mounting wall the screws that pass through the screw holes of the wall mounting flange. Finally, the locking protrusion on the inner peripheral surface is engaged with the locking protrusion to cover the screw with the flange cap.

Therefore, the interior bar can be attached to the mounting wall from inside the room without exposing the screws inside the room.
It can be expected to simplify installation work and improve interior aesthetics. Moreover, the wall mounting flange that is screwed to the mounting wall is attached to the mounting wall through the cushion material, so even if a tightening force is applied to the flange when screwing, it is buffered by the cushion material. Therefore, not only will the mounting wall surface (tiles, etc.) not be damaged, the flange cap will not come loose, and it is extremely easy to install and remove.

Thus, the intended purpose can be achieved.
