Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose intermediate holding structure used for installing a brake hose in a tire house. INDUSTRIAL APPLICABILITY The present invention is particularly useful when wiring a harness in parallel with a hose.

[0002]

2. Description of the Related Art When a brake hose or the like is mounted on a vehicle body, it is necessary not only to mount both end portions but also to hold an intermediate portion of the brake hose on the vehicle body in order to prevent interference with other parts such as tires. Therefore, various intermediate holders are used to hold the intermediate portion of the hose and allow it to be attached to other parts.

For example, as shown in FIG. 7, a metal intermediate holder comprising a plate-shaped flange portion 100 having a bolt hole 101 and a sleeve 102 extending from the flange portion 100 is known. In this intermediate holder, the sleeve 102 is clamped at the position of a nipple (not shown) inserted in the hose 300, and the hose 300 is clamped and fixed by the sleeve 102 and the nipple. Then, the bolt 200 is inserted into the bolt hole 101, and is used by being fixed with the nut 201 via the bolt hole 301 of the bracket 300 protruding from the vehicle body.

As a vehicle speed sensor for detecting the vehicle speed of an automobile, a sensor for detecting the number of rotations of wheels is effective, and an ABS speed sensor is generally used. This A
The BS speed sensor is fixed near the wheels, and the harness extending from the ABS speed sensor extends from the tire housing into the engine compartment along the brake hose.

Furthermore, in recent years, a harness such as a pad wear sensor for detecting the amount of wear of the brake pad has been arranged near the brake hose. The harness is separately routed from the brake hose in order to prevent interference with the brake hose, and is held by a bracket or the like protruding from the vehicle body by using an intermediate holding tool like the brake hose.

[0006]

However, in the conventional intermediate holding structure, the number of parts such as bolts, nipples, and intermediate holding tools is large, and the number of assembling steps is also large. In addition, the weight is increased accordingly, and it is desired to reduce the weight. If the brake hose and the harness are separately routed, a large number of brackets and intermediate holding tools are required, which is not preferable in terms of the routing space and the number of parts, and the workability in the assembling process is further reduced.

The present invention has been made in view of the above circumstances, and it is possible to hold an intermediate member with a small number of parts and to hold an intermediate member such as a harness together with the hose while preventing interference with the hose. To aim.

[0008]

The hose intermediate holding structure of the present invention for solving the above problems has a hose holding portion and a harness holding portion, and the inner diameter of the hose holding portion can be reduced as well as the outer diameter reduced by elastic deformation. A flexible elastic ring and a bracket with a bracket hole, the harness is inserted into the harness holding part, the middle part of the hose is inserted into the hose holding part, and the elastic ring is held in the bracket hole with the outer diameter reduced. The elastic ring is fixed to the bracket while being elastically contacted with the bracket and the hose.

[0009]

In the hose intermediate holding structure of the present invention, the harness is inserted into the harness holding portion of the elastic ring, the hose is inserted into the hose holding portion, and the middle portion of the hose is arranged in the hose holding portion. At this time, since the force of reducing the diameter is not applied to the elastic ring, the inner diameter of the hose holder can be made larger than the outer diameter of the hose, and the hose holder can be easily inserted into the hose holder.

By press-fitting the elastic ring into the bracket hole, the outer diameter of the elastic ring is regulated by the diameter of the bracket hole, so that the elastic ring is reduced in diameter. Since the inner diameter of the hose holding portion is reduced along with the outer diameter reduction, a part of the elastic ring forming the reduced diameter hose holding portion elastically contacts the middle portion of the hose inserted in the hose holding portion, The hose is held and fixed in the hose holder.

Further, since the hose holding portion and the harness holding portion are separately provided on the elastic ring, it is possible to hold the intermediate portion of the harness together with the hose while preventing the interference with the hose.

EXAMPLES The present invention will be specifically described below with reference to examples. (Embodiment 1) FIG. 3 shows a front view of an elastic ring used in this embodiment, and FIGS. 1 and 2 show a hose intermediate holding structure of this embodiment using this elastic ring.

The elastic ring 1 is made of polypropylene and has a substantially cylindrical ring portion 10 that defines the outer shape and a plate shape bent into a substantially U shape, and both ends are integrated with the inner peripheral surface of the ring portion 10 and are in the center. The part protrudes toward the inner diameter side of the ring part 3
It is composed of two bulging portions 11, 12, 13 and a positioning protrusion 14 protruding from the outer peripheral surface of the ring portion 10.

The ring portion 10 has a substantially cylindrical shape, and a first claw portion 15 and a second claw portion 16 which overlap each other and extend in the circumferential direction are formed on a part of the side peripheral surface. The ring portion 10 is separated by the first claw portion 15 and the second claw portion 16, and the diameter of the ring portion 10 can be changed by the overlapping distance. In addition, the side peripheral surface of the ring portion 10 has a cross-sectional mountain shape in which the central portion is high and decreases toward both end surfaces,
A ring groove 17 is formed in the central portion so as to go around the side circumferential surface once.

At the center of the ring portion 10, a hose holding portion 18 is formed in a portion surrounded by the three bulging portions 11, 12, 13. In addition, the first claw portion 15 and the second claw portion 16
Is formed at a position where the bulges 11, 12, and 13 do not exist. Therefore, when the overlapping distance between the first claw portion 15 and the second claw portion 16 becomes long and the diameter of the ring portion 10 is reduced, the hose holding portion 1 surrounded by the bulging portions 11, 12, 13 is formed.
The diameter of 8 is also reduced. In addition, the first claw portion 15 and the second claw portion 16
When the overlapping distance with and the diameter of the ring portion 10 is enlarged, the hose holding portion 1 surrounded by the bulging portions 11, 12, 13 is formed.
The diameter of 8 is also enlarged. Then, three ring-shaped spaces surrounded by the inner peripheral surface of the ring portion 10 and the bulging portion 12, the first claw portion 15, the second claw portion 16, and the one portion surrounded by the bulging portions 11 and 13. Four harness holding portions 19 are formed in one space.

In the elastic ring 1 constructed as described above, the hose 2 is first inserted into the hose holding portion 18. The force of the diameter reduction does not act at the time of this insertion, and the overlapping distance between the first claw portion 15 and the second claw portion 16 is designed to be short in that state. Therefore, the outer diameter of the ring portion 10 is large, and the diameter of the hose holding portion 18 is designed to be larger than the outer diameter of the hose 2, so that the hose 2 can be easily inserted.

Next, the harness 3 is inserted into the harness holding portion 19 surrounded by the first and second claw portions 15, the second claw portion 16 and the bulging portions 11 and 13. The harness 3 can be easily inserted into the harness holding portion 19 from between the first claw portion 15 and the second claw portion 16. The elastic ring 1 through which the hose 2 and the harness 3 are inserted is fitted into the bracket hole 40 of the bracket 4 extending from the vehicle body, and the peripheral edge of the bracket hole 40 is fixed to the bracket 4 by engaging with the ring groove 17. . At this time, the positioning protrusion 14 engages with the notch of the bracket 4 not shown, so that the elastic ring 1 is positioned in the circumferential direction.

When the elastic ring 1 is fitted into the bracket hole 40, a reducing force acts on the ring portion 10 and elastically deforms so that the overlapping distance between the first claw portion 15 and the second claw portion 16 becomes long. To do. As a result, the diameter of the ring portion 10 is reduced, and the bulging portions 11, 12, and 13 are further bulged toward the inner diameter side by the force and are elastically contacted with the hose 2, so that the hose 2 is strongly clamped in the hose holding portion 18. Is fixed. Further, the elastic ring 1 is elastically contacted with the bracket hole 40 by the elastic reaction force due to the diameter reduction and fixed to the bracket 4.

That is, according to this hose intermediate holding structure, the hose 2 and the harness 3 can be intermediately held only by the elastic ring 1, and the number of parts can be remarkably reduced as compared with the conventional case. Further, since the elastic ring 1 is made of resin, it contributes to weight reduction. (Embodiment 2) FIG. 4 shows an elastic ring 5 used in the second embodiment.
The front view of is shown with the hose 2 and the harness 3 held intermediately.

The elastic ring 5 has a shape in which four harness holding portions 50 having a C-shaped cross section are connected to each other by a bridge portion 51 in a ring shape, and the four harness holding portions 50 center the hose holding portion 52. Are formed. Further, the bridge portion 51 is composed of three pieces, and the bridge portion 51 is not formed at one location between the harness holding portions 50, but serves as the separation portion 53. In this elastic ring 5, since the diameter of the hose holding portion 52 is also reduced by elastically deforming the separation portion 53 so as to narrow the gap, the separation portion 53 is fitted to the bracket 4 as in the first embodiment. The space between the two is narrowed and the hose 2 can be held. In addition, the harness holding portion 50 has notches 54, respectively.
Therefore, it is easy to insert the harness 2 as in the first embodiment. (Embodiment 3) FIGS. 5 and 6 show a hose intermediate holding structure according to a third embodiment. In this embodiment, the hose 2 and the harness 3 are integrally held by the protector 6, and the elastic ring 7
It is held together with the protector 6.

The elastic ring 7 has the same structure as the elastic ring 1 of the first embodiment except that the elastic ring 7 has four bulges.
The protector 6 is held between the individual bulges 70 together with the hose 2 and the harness 3. The protector 6 is formed of resin in a spiral shape as a whole, and has a cross-sectionally irregular shape having a hose holding portion 60 and a harness holding portion 61. Then, with the hose 2 inserted through the hose holder 60 and the harness 3 inserted through the harness holder 61, the hose holder 60 is held in the center of the four bulging portions 70, and the harness holder 61 is It is held between the pair of bulging portions 70.

In the hose intermediate holding structure of this embodiment, the four bulging portions 70 hold the hose holding portion 60 by the reduced diameter of the elastic ring 7 by fitting the hose holding portion 60 into the bracket hole 40 of the bracket 4. The diameter of the holding portion 60 is reduced and the hose 2
The hose 2, the protector 6 and the harness 3 are intermediately held by sandwiching the. Since the protector 6 is deformable except for the intermediate holding portion, the hose 2 and the harness 3 can be integrally displaced, and the mutual interference is effectively prevented.

[0023]

According to the hose intermediate holding structure of the present invention, the hose can be held intermediately by simply fitting the elastic ring into the bracket hole of the bracket and reducing the diameter thereof. Can be significantly reduced, and cost and weight can be reduced.

Since the harness can be held intermediately at the same time in a state where interference with the hose is prevented, an intermediate holding tool for the harness and a bracket are not required, and the number of parts can be further reduced. Further, the hose and the harness can be easily routed in parallel, and the routing space can be reduced.
