BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube mounting device used for fixing a pipe of an automobile or the like.

[0002]

2. Description of the Related Art In order to fix a pipe of an automobile to a vehicle body, a tube-shaped main body portion wound in a cylindrical shape so as to hold an outer periphery of a tube to be fixed is provided at both ends of the main body portion. A tube mounting device having a clamp comprising a mounting piece portion fixed to a supporting portion in a superposed state at the time of mounting is used.

One example will be described with reference to FIG. 5. In order to fix a tube T, a clamp 12 is used. The clamp 12 is integrally formed with a tubular main body portion 12a and one end of the main body portion 12a. Continuous strip-shaped mounting piece 12
b and a band-shaped mounting piece 12c integrally connected to the other end of the band-shaped main body 12a. Both mounting pieces 12b, 1
2c are superimposed on each other when fixed. on the other hand,
A spool 13 made of an elastic material such as rubber is provided,
The spool 13 has a cylindrical portion 13a through which the tube T is inserted.
And the flanges 13b at both ends thereof. The spool 13 is provided with a slit 14 in the longitudinal direction.

In order to fix the tube T, a flat open spool 13 is wound around the tube T,
The flat main body 12a of the clamp 12 is wound around the spool 13, the mounting pieces 12b and 12c are overlapped as shown in FIG. The protruding piece 16 is bent with respect to the outer surface of the mounting piece portion 12b, the two mounting piece portions 12b and 12c are integrated, and a mounting bolt (not shown) is screwed into the support member 17 of the vehicle body through the hole 15. When installation is complete, the flange 1
3b is in contact with both side edges of the band-shaped main portion 12a,
The axial movement of the spool 13 with respect to the clamp 12 is prevented.

A tube mounting device having the same principle as described above is described in, for example, Japanese Utility Model Laid-Open No. 62-110680.

[0006]

In the conventional tube mounting apparatus described above, it is necessary to form a spool by using a mold. In addition, it is necessary to prepare a spool of a different size according to the diameter of the tube T.
There is a problem that the mounting is not completed unless two steps of a step of fitting the spool 13 into the spool 13 and a step of holding the spool 13 with the clamp 12 are performed. Furthermore, spool 1
3 cannot be temporarily assembled with the clamp 12 in advance.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to eliminate the need to mold an elastic material interposed between a clamp and a tube, and to provide an elastic material. It is not necessary to prepare variously according to the diameter of the tube, and an object of the present invention is to provide a tube mounting apparatus capable of completing the mounting operation in one step by temporarily assembling a clamp and an elastic material.

[0008]

According to the present invention, in order to achieve the above-mentioned object, a belt-shaped main body which is wound in a cylindrical shape from an open state so as to hold an outer periphery of a tube to be fixed,
In a tube mounting device having a clamp which is integrally provided at both ends of the main body portion and is fixed to the support portion in a state of being overlapped with each other at the time of mounting, a longitudinal direction is provided at a central portion of the band-shaped main body portion of the clamp. To form a long hole,
On the other hand, an inner peripheral surface of the band-shaped main portion is formed in a state where a strip of an elastic material formed in a central portion along the longitudinal direction is inserted into the elongated hole from the inside of the cylindrical band-shaped main portion. Into the strip so that the tube is held inside the strip.

[0009]

[Function] A ridge of an elastic material strip is inserted from the inside of the clamp into the elongated hole of the band-shaped main portion of the clamp in an open state such as a plane, and temporarily assembled, and the tube is inserted through the strip while caulking the clamp to form a tube. Hug. When both mounting pieces of the clamp are overlapped and the mounting piece is attached to the support part,
The tube is fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a clamp 2 used in the present invention.
The unfolded shape of the clamp 2 in the planar bear before mounting is as shown in FIG. 2, and the clamp comprises a band-shaped main body 2a, a band-shaped mounting piece 2b integrally connected to one end of the main body 2a, and a main body. An annular mounting piece portion 2c is formed integrally with the other end of 2a. A long hole 6 is formed in the central portion of the main withstand portion 2a in the longitudinal direction, and a guide protruding piece 7 is formed on a side edge of the main body 2a near the mounting piece 2b.
A protruding piece 8 is also formed at the center of the end of the mounting piece 2c.
Further, mounting holes 5, 5 of the same size are provided in both mounting pieces 2b, 2c.
Is provided.

In the clamp 2 as described above, in the mounted state, as shown in FIG. 1, the band-shaped main portion 2a is bent into a cylindrical shape, the two mounting pieces 2b, 2c are overlapped, and the mounting hole 5 is formed. , 5 are matched. Also, the guide projections 7, 7
Are bent in a parallel state, and the protruding piece 8 is bent so as to stand up.

FIG. 3 shows the elastic material interposed between the tube to be mounted and the clamp 2. The elastic member is made of a strip 9 of rubber or the like, and a ridge 9b is formed in the center of one surface of the band-shaped main body 9a along the longitudinal direction.
The width and height of the ridge 9b are set to appropriate values so as to fit into the elongated holes 6 of the clamp. In order to prevent escape from the elongated hole 6 of the ridge 9b, it is preferable to enlarge the leading edge of the ridge as shown in the figure.

In order to fix the tube T using the clamp 2 and the strip 9 described above, one side (the inner surface of the cylinder) of the clamp 2 which is open in a plane or the like is appropriately fixed. The ridge 9b of the strip 9 cut to an appropriate length is fitted into the elongated hole 6, and the strip 9 is brought into close contact with the one surface of the clamp. Thereby, the strip 9 is easily temporarily assembled to the clamp 2.

As shown in FIG. 4, the strip 9 and the clamp 2 temporarily assembled as described above are wound so as to hold the tube T, and the mounting pieces 2b and 2c are overlapped to form the mounting holes 5 and 5. Then, the protruding piece 8 is bent upward. Before the main body 2a of the clamp 2 is crimped into a cylindrical shape and brought into the state shown in FIG. 4, the guide projections 7, 7 are bent in a parallel state as shown in FIG. It serves as a caulking guide. When the clamp 2 is crimped into a cylindrical shape, the strip 9 also becomes cylindrical accordingly and holds the tube T. Then, the bolt 2 (not shown) is screwed into the supporting portion through the mounting holes 5, 5, whereby the clamp 2 is tightened, and the strip 9 elastically grips and fixes the tube T. The strip 9 made of an elastic material hits and protects the outer peripheral surface of the tube T whose surface is treated (for example, resin-coated). Further, since the ridges 9b are fitted into the long holes 6, the strip 9 does not shift with respect to the clamp in the longitudinal direction of the tube T.

[0016]

According to the tube mounting apparatus of the present invention, the strip of elastic material does not need to be formed by a mold, and can be manufactured by extrusion, so that it is inexpensive and independent of the tube diameter. The same material can always be used, and it may be used by cutting it into an appropriate length according to the diameter of the tube. In addition, it is only necessary to temporarily assemble the strip into the clamp with a simple operation of inserting a ridge into the elongated hole in a state where the clamp is flat or the like, and then attach the tube to the clamp. The installation of the tube is completed in the process. Therefore, the mounting operation can be performed more quickly and easily than in the conventional case.
