2. Description of the Related Art Generally, a pipe such as a towel bar or a grip bar is formed by bending both ends of the pipe in the same direction so as to be substantially orthogonal to the pipe. The bending of the end of this pipe is performed by a press machine, after bending one end, the end of the other pipe is bent and both ends of the bent pipe are parallel in the same direction. Is formed. However, since the pipes are bent one by one, parallelism is often not achieved. In addition, the pipe has a polishing process, and during this polishing process, heat is applied to the pipe to cause a springback phenomenon, which opens to the outside, and this is also one of the reasons why parallelism cannot be obtained.

Conventional pipes such as towel bars and grip bars take dimensional errors into consideration, but in reality, dimensional errors only take into account dimensional errors that occur on the same plane. There are some mounting brackets that can be moved back and forth on the same plane.

[Problems to be Solved by the Invention]

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the invention according to claim 1. Reference numeral 1 is a pipe such as a towel bar or a grip bar, 1a is an end portion bent in the same direction as the pipe 1 so as to be substantially orthogonal, and 1a.
Reference characters b denote screws formed on the inner peripheral surface of the pipe 1 on the end side. Reference numeral 2 is a pipe fitting such as a towel bar or a grip bar that is connected to the screws 1b formed on the inner peripheral surfaces of both ends 1a and 1a of the pipe 1. Pipe fittings 2 are roughly classified,
The pad plate member 3, the top member 4, and the connecting ring 5 are components. That is, the backing plate member 3 is a backing plate member fixed with the bolts 7 while being in contact with the mounting surface 6 such as a wall. The backing plate member 3 has a through hole 3a formed in the center thereof.

The top member 4 is formed into a bowl-shaped curved surface (a large diameter on the upper side and a small diameter on the lower side) 4a on the outer peripheral surface, and the curved surface 4a.
The rod-shaped base portion 4b connected to the lower side is fitted into the through hole 3a of the pad plate member 3. Further, a bolt insertion hole 4c for fixing to the mounting surface 6 is formed at the center of the top member 4. A pin 8 protruding to the outside is formed at an appropriate position on the curved surface 4a of the top member 4.

The connecting ring 5 has the pipe 1 on the outer peripheral surface thereof.
Screws 5a that engage with the screws 1b on the inner peripheral surfaces of both end portions 1a, 1a are engraved. Further, the connection ring 5 has a flange 5b formed toward the lower inner side of the inner peripheral surface thereof. The collar 5b is loosely fitted to the outside of the outer peripheral surface which is the bowl-shaped curved surface 4a of the top member 4, and the collar 5b is prevented from coming off from the top member 4.
Is formed to be smaller than the diameter of the upper portion of the outer peripheral surface of the top member 4. Then, the connecting ring 5 is movable in all directions within the range regulated by the upper portion of the outer peripheral surface of the top member 4, and the collar 5b is provided.
A free-fitting groove 5c which is rotated by being restricted by the pin 8 is formed in the. Therefore, not only the connecting ring 5 can be moved in the front, rear, left and right directions in a plane, but also the connecting ring 5 can be three-dimensionally tilted or three-dimensionally rotated. Even if a three-dimensional error occurs in both ends 1a, 1a of 1, the three-dimensional error can be sufficiently absorbed and the device can be easily attached to a wall surface or the like.

3 and 4 show an embodiment of the invention according to claim 2. In the invention according to claim 2, the connection ring 5 of the wall-side fittings connected to the pipe-side fittings of the invention according to claim 1 can be three-dimensionally tilted or three-dimensionally rotated. In addition to this, the pipe connecting fitting 11 that is screwed into the connecting ring 5 to be connected can also be three-dimensionally tilted or three-dimensionally rotated. Therefore, since the basic structure of the pipe fitting 2 is the same as that of the embodiment of the invention according to claim 1, the description of each member will be omitted. The only difference is that a rising flange 3b is formed on the outer peripheral edge of the pad plate member 3, and a screw 3c that is screwed with the bracket 10 on the pipe 1 side is engraved on the outer peripheral surface of the rising flange 3b.

Further, the pipe side fittings 9 such as a towel bar and a grip bar according to the present invention have the pipe 1 such as a towel bar and a grip bar in the same direction so that both ends 1a and 1a of the pipe 1 are substantially orthogonal to the pipe 1. The mounting substrate 12 is fixed to each of both ends of the pipe 1 which is bent into the above. Mounting board 1 of this example
Reference numeral 2 is inserted into the tip of the bent pipe 1, and a screw fixing hole 12a is formed in the inserted side surface to fix the screw (not shown) from the outside of the pipe 1. And the mounting substrate 12
A pipe-side top member 13 having an outer peripheral surface formed in a bowl-shaped curved surface 13a is attached to the central portion of the. A screw 13c is engraved on the outer peripheral surface of a rod-shaped portion 13b that is connected to the outer peripheral surface base of the pipe-side top member 13.

The rod portion 13b is inserted into a through hole 12b formed in the central portion of the mounting board 12, and a screw 13c penetrating the through hole 12b is fixed by tightening a nut 14 from the back surface of the mounting board 12.

The inner diameter of the collar 11b is the top member 13 on the pipe side.
The inner diameter of the collar 11b is formed smaller than the diameter of the upper portion of the outer peripheral surface of the pipe-side top member 13 so that the collar 11b does not slip out of the pipe-side top member 13. Thus, the pipe-side connecting fitting 11 is movable in all directions within the range regulated by the upper portion of the outer peripheral surface of the pipe-side top member 13.

[0014]

As can be seen from the above description, the present invention eliminates these three-dimensional errors even if both ends of the pipe have three-dimensional errors that occur during the bending and polishing steps by the press machine. It is possible to provide a pipe fitting such as a towel bar or a grip bar that can be sufficiently absorbed and easily mounted on a wall surface or the like. Since the connecting ring of the wall-side mounting bracket is loosely fitted so that the outer peripheral surface does not come out of the top member formed on the bowl-shaped curved surface, the movement of the connection ring is restricted by the bowl-shaped curved surface The original movement is possible, and the loose fitting groove formed in the connection ring and the pin partially inserted in the loose fitting groove allow the movement in the turning direction to be rotatable while being restricted by the pin. It is possible to effectively absorb an error such as a bending process which occurs at both ends of the and to securely attach it.

Particularly, not only the wall-side fitting of the pipe fitting but also the pipe-side fitting of the pipe fitting is restricted to the bowl-shaped curved surface of the outer peripheral surface of the pipe-side top member, and the bowl-shaped curved surface thereof. By loosely fitting it so that it does not come out of it, three-dimensional movement is possible, both sides are three-dimensionally moved, and errors such as bending at both ends of the pipe are also dealt with. Therefore, the ease of mounting is further increased.
