Description

[Detailed Description of the Invention] <Industrial Application Field of the Present Invention> The present invention relates to a holder integrally formed of plastic for holding a rod-shaped object and fastening it to a mounting hole.

<Prior Art> (Fig. 9) Various rod-shaped objects are wired inside automobiles, such as rods used in automobile door locking mechanisms and torsion bars used in trunk lid opening mechanisms. In order to prevent vibrations during running, the intermediate portions of these rod-like objects are fitted and held with plastic holders.

FIG. 9 shows a conventional holder for holding two rod-like objects (for example, two torsion bars) for this purpose.

That is, in FIG. 9, the holder 1 is integrally molded of plastic, and a locking part 3 is provided protrudingly on one side of the base 2, and holding arms 4, 5, and 3 are provided on the opposite side.
6 is provided protrudingly. Between the holding arms 4 and 5 and between the holding arms 5 and 6, circular holding grooves 7 and 8 which are open at the top (in FIG. 9) are formed, respectively. The holding arms 4 and 6 can be elastically deformed laterally with appropriate elasticity.

A plurality of beads 7a, 8a are provided on the inner walls of the holding grooves 7, 8 to protrude in the axial direction of the holding grooves 7, 8.

Therefore, after the locking part 3 is locked in the mounting hole (not shown), the rod-shaped objects A, A are pushed in perpendicularly to the axial direction from the distal ends of the holding arms 4, 5 and 5, 6. Then, the beads 7a, 8a come into contact with the rod-shaped objects A, A, and the holding arms 4, 6 are slightly pushed outward, and the elastic return force causes the rod-shaped objects A, A,
A is now held between them.

In this way, the rod-shaped object A is held in a state in which it contacts the beads 7a, 8a and pushes the distal ends of the holding arms 4, 6 outward against their elasticity. Even if there is a slight difference in the outer diameter, it will not wobble and will be held with strong holding force.

<Problems to be Solved by the Present Invention> However, in the conventional holder 1 having such a structure, (a) as described above, it is difficult to absorb the variation in the outer diameter of the rod-shaped object A to be fitted and to prevent wobbling; In order to prevent this from occurring, the holding arms 4 and 6 must be hard enough to be easily bent. However, if the rod-shaped object A is made to bend easily, if it is subjected to severe vibration, or if it is subjected to force in a torsion or bending direction as in the case of the torsion bar for opening the trunk lid, the tip of the holding arm will It becomes easy to fall off.

On the other hand, if the hardness is increased to make it difficult to detach, it will not be able to bend sufficiently, and therefore it will not be able to sufficiently absorb variations in the outer diameter of the rod-shaped object A, resulting in wobbling.

(b) When the rod-like object A is parallel to the axial direction of the holding grooves 7 and 8, the rod-like object A is in line contact with the beads 7a and 8a over the entire length in the axial direction. When holding two rod-like objects A, A that are not parallel to each other, the rod-like objects A, A are not parallel to the axial direction of the holding grooves 7, 8, so that a line is formed over the entire length of the beads 7a, 8a. Since they are not in contact and are in contact only at the ends in the axial direction, the holding force is weak and they tend to come off from between the tips of the holding arms 4, 5, and 6.

<Means for solving the above-mentioned problems> In order to solve the above-mentioned problems, the rod-shaped object holder of the present invention includes: a base; and a projection provided on one side of the base for locking into a mounting hole. a locking part; a plurality of holding arms protruding from the opposite surface of the base and forming a groove inside; a plurality of holding arms provided along the circumferential direction on an inner wall of the groove;
an annular pedestal projecting circumferentially into the groove; and a cylinder protruding from the pedestal in a substantially axial direction of the groove, for fitting and holding a rod-shaped object that is inserted from the distal end side of the holding arm. It is characterized by having a shaped part.

<Function> As described above, in the rod-shaped object holder of the present invention, the locking part is locked in the mounting hole, the rod-shaped object is inserted into the holding arm almost perpendicularly to the length direction, and the rod-shaped object is removed from the base part. It fits into a cylindrical part that protrudes in the axial direction.

Variations in the outer diameter of the rod-shaped object are absorbed by the elasticity of the holding arm and the elasticity of the cylindrical section. Furthermore, even if the rod-shaped object is not parallel to the axial direction of the groove in the arm section, the cylindrical section deforms to follow the axial displacement of the rod-shaped object, so surface contact is maintained.

<Embodiment of the present invention> (Figs. 1 to 5) Hereinafter, an embodiment of the present invention will be described based on the drawings.

1 to 5 show an embodiment of the present invention.

In these figures, reference numeral 10 denotes the rod-shaped object holder of this embodiment, which is integrally molded from plastic.

A locking portion 12 is provided in a protruding manner on one side of the base portion 11 .

The locking portion 12 consists of a rectangular base portion 12a and locking pieces 12b and 12c that protrude from its lower surface (as shown in FIG. 1) and intersect in a cross shape.

The base part 12a has a rectangular mounting hole P1 (the fourth
It is set to have a rectangular shape smaller than the rectangular mounting hole P1 so that it can be inserted into the mounting hole P1 with some play.

The locking pieces 12b and 12c have tapered portions 12b' and 12c' on the base portion 12a side and the tip side, respectively, so that the center bulges outward. The central bulging portions 12b'', 12c'' are bulged in the center in a chevron shape, and the length of the locking pieces 12b, 12c in the horizontal direction (in FIG. 2) is longer than the length of the diagonal line of the rectangular mounting hole P1. It is set to a slightly smaller length.

On the opposite side of the base 11, holding arms 13, 14,
15 is provided protrudingly. Arc-shaped grooves 16 and 17 are formed between the holding arms 13 and 14 and between the holding arms 14 and 15, respectively, and are open at the top.

At the axial centers of the grooves 16 and 17, annular pedestals 18 and 19 of a predetermined width are provided along the circumferential direction, respectively.
is installed protrudingly.

Thin cylindrical portions 20 and 21 protrude in the axial direction from both sides of the annular platform portions 18 and 19 in the axial direction. The cylindrical parts 20 and 21 have a radius that gradually decreases, and have a plurality of axial cuts 22 and 21, respectively.
It has 23.

<Operation of the above embodiment> Next, the operation of the above embodiment will be explained.

First, as shown in FIG. 4A, after aligning the cross-shaped locking pieces 12b and 12c of the holder 10 in the diagonal direction of the rectangular mounting hole P1 of the plate P and inserting them into the mounting hole P1, 4 As shown in Figure B, the holder 10
Rotate approximately 45 degrees. As a result, the locking piece 12
The bulges 12b'' and 12c'' of bulges 12b and 12c are engaged with the sides of the mounting hole P1, and the rectangular base portion 12a is connected to the mounting hole P1.
It is inserted with some play inside.

For this reason, the holder 20 is attached to the plate P with the rectangular platform 1.
The corner 12' of the plate 2a is rotatably locked within the range restricted by the side of the rectangular mounting hole P1 of the plate P.

The next rod-shaped object A is held by the opposing holding arms 13 and 14.
When pressed from the opening at the tip in the direction of the groove 16,
The arm portion 13 is bent outward by the rod-like object A, the opening widens, and the rod-like object A enters the groove portion 16. Since the cylindrical portions 20, 20 within the groove portion 16 have a radius that gradually decreases toward both sides in the axial direction,
The rod-shaped object A comes into contact with both ends 20a, 20a of the cylindrical parts 20, 20. Therefore, when the rod-shaped object A is further pushed in, the cylindrical parts 20, 20 have both ends 20a, 20a
The rod-shaped object A is expanded from the side by the cuts 22, 22 against its elasticity, and this elastic return force causes the rod-shaped object A to
is tightly wrapped in the cylindrical parts 20, 20 and fitted as shown in FIG.

The rod-shaped object A is fitted into the other cylindrical portions 21, 21 in the same manner.

In this way, the rod-shaped objects A, A are held by the elasticity of the cylindrical parts 20, 21, and the holding arm parts 13,
It is also held by the elasticity of 14 and 15. Therefore, even if there is variation in the outer diameter of the rod-shaped object A,
Since it is absorbed by the two-stage elasticity of the cylindrical parts 20, 21 and the holding arms 13, 14, 15, it is held without wobbling.

If the cylindrical parts 20 and 21 are made thin to increase the deflection, and the holding arms 13, 14 and 15 are made thick and the flexure is set to be small, the wobbling of the rod-shaped object A within the cylindrical parts 20 and 21 can be reduced. retaining arm 1
The two requirements of preventing the distal ends of Nos. 3, 14, and 15 from falling out from the openings can be simultaneously achieved.

Further, the cylindrical portions 20 and 21 are the annular base portions 18 and 19.
Since it protrudes from both sides in the axial direction, even if the held rod-shaped object A deviates from the axial direction, it will deform accordingly (and even with this deformation, the elastic force surrounding the rod-shaped object A is weak). ), so stick-shaped object A
Since the state of surface contact with the rod-shaped object A is maintained and the holding force to the rod-shaped object A is sufficiently maintained, it will not fall off.

<Other embodiments of the present invention (Figs. 6 to 8) Figs. 6 to 8 show other embodiments of the present invention.

This embodiment is of a lock type, and a thin bendable hinge part 30 extends from the tip of the holding arm part 13.
A lid portion 31 extends through the.

A vertical plate portion 32 is provided protruding from the tip of the lid portion 31 . A lock claw portion 32a is provided protruding from one end side of one side of the vertical plate portion 32, and a lock claw portion 32b is provided protruding from the other end side of the opposite surface.

Further, on the outer side of the holding arm 15, a substantially L-shaped engagement arm 33 is provided to protrude from the base 11.

Engagement parts 15a and 33a for locking the lock claw parts 32a and 32b are provided at one end and the other end of the opposing sides of the distal end of the holding arm part 15 and the distal end of the engagement arm part 33, respectively. It is installed protrudingly. The upper surfaces of the engaging portions 15a, 33a are provided with tapered portions 15a', 33a' through which the lock claw portions 32a, 32b are guided.

Also, on both sides of the tip 14a of the central holding arm 14, retainers 14b and 14c are provided to protrude diagonally.

Further, in the center of the lid part 31, there is provided a bent part 31a which is bent into a concave shape so as to fit the tip part 14a in the locked state.

In this embodiment, similarly, the locking portion 12 is connected to the mounting hole P.
1, and rod-shaped objects A and A are attached to the cylindrical parts 20 and 21.
However, in order to completely prevent the rod-shaped object A from falling off, as shown in FIG. , 32b are press-fitted between the engaging arm portion 33 and the holding arm portion 15 to form the engaging portions 15a, 32b.
33a to lock it.

Although the embodiments of the present invention have been described above, the present invention is not limited to these, and it goes without saying that various modifications can be made in the configuration of each part. For example, the cylindrical parts 20 and 21 can be Although the case in which the side radius gradually decreases is illustrated, it is not necessary to gradually decrease it in this way, and the notches 22 and 23 do not need to be provided, and the cylindrical portions 20 and 21 may be polygonal instead of circular. good. Further, the locking portion 12 may also have any other shape such as an anchor shape, an umbrella shape, etc., instead of the shape of the above embodiment.

<Effects of the present invention> As explained above, in the rod-shaped object holder of the present invention, a cylindrical part is provided in the groove between the plurality of holding arms,
Since the rod-shaped object is fitted in this cylindrical part, (a) Even if there is variation in the outer diameter of the rod-shaped object, the variation can be absorbed in two stages by the elasticity of the holding arm and the elasticity of the cylindrical part. , can be held without wobbling. Moreover, since the rod-shaped object is held with two-stage elasticity, the overall elasticity can be increased, and therefore the rod-shaped object can be prevented from falling off due to external force or vibration.

(b) Furthermore, since the cylindrical portion protrudes from the annular base portion in the axial direction, even if the rod-shaped object to be held deviates from the axial direction, it will deform following the iron. Therefore, since surface contact with the rod-shaped object is maintained, there is no reduction in holding force due to deviation in the axial direction of the rod-shaped object as in the past, preventing it from falling off and strongly holding it even if it shifts from the axial direction. be able to.
