Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube holder for holding a tube such as a fuel tube of an automobile.

[0002]

2. Description of the Related Art Conventionally, a fuel tube of an automobile has been attached to an underbody of the automobile via a resin holder. The conventional holder 30 is as shown in FIG. 4 and includes a main body 31 and a cover 32. Both are molded mainly of a hard resin material, but in order to prevent the pressure fluctuation generated in the tube from being transmitted to the body side, a portion for holding the tube, that is, an opposing surface of the main body 31 and the cover 32. Only the inner peripheral surface of the holding groove 33 formed in the above is formed of a soft resin material.

The cover 32 is connected to one end of the main body 31 via a hinge 34 and can be opened and closed with respect to the main body 31. On the other hand, a lock claw 35 is formed on the free end side of the cover 32 so that when the cover 32 is closed, the lock claw 35 can be elastically engaged with a hooking edge 36 formed on the facing portion of the main body 31. It has become.

[0004]

However, the above-mentioned conventional holder has the following problems.

When closing the cover 32, the hinge 3
4 may cause cracks. As described above, since the hinge portion 34 is formed of a hard resin material,
The hinge portion 34 needs to be formed as thin as possible so that a good hinge function can be obtained. Therefore, the formed meat is hard to turn around in the thin portion, and the thickness quality of this portion is likely to vary. Since the hinge portion 34 is a portion to which a tensile load is applied at the time of the closing operation, if there is a variation in the molding, a crack is easily generated.

The locking operation of the cover 32 varies. Since the hinge portion 34 also varies in its length (the length connecting the cover portion 32 and the main body portion 31), the rotation locus of the cover portion 32 also varies. Therefore, a problem has been pointed out that the engaging operation between the lock claw 35 and the hooking edge 36 when the cover 32 is closed is not stably performed.

There is a great difficulty in manufacturing a mold for molding the holder 30. As described above, if the thin hinge portion 34 is to be formed, a delicate dimensional accuracy is required for the hinge portion forming portion on the mold side. Therefore, mold processing requires a lot of labor and cost.

The present invention has been devised in view of the conventional problems described above, and an object of the present invention is to provide a tube holder capable of solving the above problems. .

[0009]

According to a first aspect of the present invention, there is provided a main body provided with a holding groove for pushing a tube in a longitudinal direction and accommodating the main body therein. A cover that is openably and closably attached to the body via a hinge portion, and that holds the tube housed in the holding groove by being locked to the main body by locking means. Wherein the hinge is formed of a soft resin material.

According to a second aspect of the present invention, in the first aspect, the cover is formed integrally with the hinge at least on a mounting surface side.

[0011]

According to the first aspect of the present invention, since the hinge portion is formed of a soft resin material, the hinge function is exhibited even when the hinge portion is formed thicker than when the hinge portion is formed of a hard resin material. be able to. Therefore, when a locking operation is performed on the cover portion, even if a pulling load acts on the hinge portion, it can reliably resist this.

According to the second aspect of the present invention, when the tube holder is mounted, the mounting surface formed of the soft resin material faces the surface on the fixing member side. When mounted in close contact, vibration can be absorbed by the cushion function of the mounting surface.

[0013]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. However, also in this embodiment, a description will be given by taking a holder for holding a fuel tube for an automobile as an example.

FIG. 1 shows the entire holding tool H in the present embodiment. The holding tool H in the present embodiment is integrally formed of a main body 1 and a cover 2. And
As described in order, these are hard resin materials (for example,
There is a part formed of a soft resin material (a thermoplastic elastomer material) and a part formed of polypropylene or polyethylene, etc., and they are integrated by insert molding.

The main body 1 has a substrate 3 made of a hard resin material, and a stud mounting portion 4 is formed continuously at one end thereof. The stud mounting portion 4 is a portion to be engaged with a stud bolt 5 erected on the body panel B by welding, and is formed in a rectangular parallelepiped shape in the drawing. A through hole 6 into which the stud bolt 5 can be loosely inserted is formed in the center portion in a vertical direction. Further, a pair of locking claws 7 are provided inside the through hole 6 so as to face each other, and can be elastically engaged with the threads of the stud bolt 5. However, FIG. 3 shows a case where the fixing to the body panel B side is performed only by the engagement between the locking claw 7 and the stud bolt 5, but the stud bolt 5 is further protruded from the through hole 6 and the nut is used. The fastening to the body panel B side may be performed more securely by tightening.

Further, a hook claw 8 protrudes in the form of a hook from the outer surface of the stud mounting portion 4 so that the cover portion 2 can be hooked here and held in a closed state.

A tube holding portion 9 made of a soft resin material is laminated on the substrate 3 described above. The tube holding portion 9 is laminated on the substrate 3 by insert molding. However, since both are made of different materials, they have poor adhesion.
Therefore, in this embodiment, mechanical bonding is also achieved. That is, as shown in FIG. 2 or FIG.
Bridge-shaped connecting pieces 10 are formed at a plurality of locations on the substrate 3, and in each connecting piece 10, the molded meat (soft resin) on the tube holding section 9 side can be turned from the front side to the back side. , And the substrate 3.

On the upper surface of the tube holding portion 9, a plurality of holding grooves 11 having a substantially U-shaped cross section are provided in parallel. Each holding groove 11 can hold the corresponding tube 12 over a predetermined length range along the longitudinal direction, but each holding groove 11 has a corresponding tube diameter so as to wrap the corresponding tube 12 with elastic force. The groove width is set slightly narrower than that. In the illustrated embodiment, a plurality of groove widths of the holding groove 11 are set so as to hold the tubes 12 having a plurality of diameters. All of them open upward, but the depth of these grooves is such that the corresponding tube 12 is completely buried or
2 is set so that the outer peripheral surface slightly protrudes from the surface of the tube holding portion 9.

The cover 2 is integrally connected to one end of the tube holding portion 9 (the end opposite to the stud mounting portion 4) via a hinge portion 13. As shown in FIG. 2, the hinge portion 13 is slightly thinner than a continuous portion from the tube holding portion 9 side, but is sufficiently thicker than the hinge portion 13 formed of a conventional hard resin material. Meat setting. The cover 2 extends straight with almost the same width as the tube holder 9, and the surface facing the tube holder 9 is in close contact with the upper surface of the tube holder 9 when the cover 2 is closed. A holding surface 14 for holding the tube 12 housed in each holding groove 11, and the opposite surface is a body panel B
The mounting surface 19 is in contact with the mounting surface 19. As described above, since the small-diameter tube 12 is accommodated in the holding groove 11 in a state of being buried in the holding groove 11, the pressing projection 1 is provided on the pressing surface 14 at a position corresponding to the small-diameter tube 12.
5 are arranged in two places as shown in the figure.
A relief recess 16 is formed in a portion corresponding to 2.

The cover 2 is formed to have a length that can cover the upper surface of the stud mounting portion 4 when the closing operation is performed, and this portion covers the entire upper surface of the stud mounting portion 4. It is formed so as to be widened. Further, a through hole 17 is formed in the widened portion so as to be able to communicate with the through hole 6 and to allow the stud bolt 5 to be loosely inserted when the cover 2 is closed. Further, the distal end portion of the cover portion 2 is bent at a substantially right angle in accordance with the outer shape of the stud mounting portion 4, and a locking hole 18 for locking the hook claw 8 is opened here. However, the natural length of the cover portion 2 is set so that the locking hole 18 cannot be locked to the hook claw 8 unless the cover portion 2 is pulled and elongated.

Next, the operation and effect of this embodiment configured as described above will be specifically described. First, the tubes 12 corresponding to the respective holding grooves 11 are pushed in along the longitudinal direction with the cover 2 opened. At this time, each tube 1
2 is loosely held by the elastic force of the holding groove 11,
It is not easily displaced or dropped in the axial direction. Next, the cover part 2 is rotated around the hinge part 13 while being pulled to cover the tube holding part 9 and the stud mounting part 4, and the hook claw 8 is locked in the locking hole 18. In this way, the pressing surface 14 of the cover part 2 is
In order to hold each tube 12 in close contact with the opposite surface of
Each tube 12 is held. At this time, even in the small-diameter tube 12 (the two tubes on the left side in FIG. 3), the projection 15 presses the outer peripheral surface of the tube 12, so that the small-diameter tube 12 does not rattle inside. In addition, since each tube 12 is surrounded by the soft resin from almost the entire circumference, the pulsation in the tube 12 is absorbed by these and is not transmitted to the body panel B side.

When the holders H are attached to the tubes 12 as described above, the cover 2 faces the body panel B, and the shaft ends of the stud bolts 5 are inserted through the through holes 17. When the cover 2 is inserted until it comes into close contact with the body panel B, the final locking position of the locking claw 7 and the stud bolt 5 is determined, and the entire holding tool H is prevented from coming off.

Now, the effects of the present embodiment will be enumerated as follows. First, since the hinge portion 13 is formed of a soft resin material, the thickness can be secured as compared with the related art, so that a situation that causes a crack can be avoided. Also, because it is thicker than before,
Since the dimensional accuracy of the mold is reduced, the labor required for manufacturing the mold can be reduced, and the manufacturing cost can be reduced. Furthermore, since the hinge portion 13 is formed of a soft resin material, the closing operation of the cover portion 2 can be performed while pulling and extending the hinge portion 13. Therefore, hook claw 8
Even if the positional relationship between the locking hole 18 and the locking hole 18 is displaced during molding, this can be absorbed.

Further, in this embodiment, the hinge 13
The cover H is made of a soft resin material, and this side is brought into close contact with the body panel B.
It can also exert a cushioning function against impact force when hit by a stepping stone or the like. In addition, compared to the conventional two-layered structure obtained by converting the cover portion 2 into a soft resin, the cover portion 2 as a whole becomes thinner, and the height of the entire holder H can be reduced. It can also be expected that manufacturing costs will be reduced due to material reduction.

The present invention can be variously modified.
The following modifications are also included in the technical scope of the present invention.

The hinge portion 13 needs to be formed at least from a soft resin, but the cover portion 2 does not necessarily need to be formed from a soft resin material.

In such a case, a structure in which a metal or hard resin material is inserted into the cover portion 2 as a core material may be considered.

Various types of locking structures for the stud bolt 5 are conceivable, and therefore, the stud mounting portion 4 is not limited to those of the present embodiment.
