Description

  The present invention relates to an assist grip that is assembled to a vehicle body side panel or the like.

  An assist grip is provided on the ceiling of the vehicle compartment side. As shown in FIG. 10, for example, the assist grip 9 includes a long grip body 91, a hinge 92, a clip 93, and a cap 94. As shown in FIG. 11, the grip body 91 has a recess 91a provided at both ends thereof, and a pair of bearing holes 91b formed in mutually opposing portions of the peripheral wall of the recess 91a. The hinge 92 is housed in the recess 91a, and has a frame portion 92b having a clip holding hole 92a, and an arm portion 92d extending from a pair of extending base portions 92c at a predetermined interval in the frame portion 92b. The arm portion 92d has a shaft 92e pivotally supported by a pair of bearing holes 91b provided in the grip body 91. The clip 93 is inserted with the tip end portion 93a protruding into the clip holding hole 92a, and the base end portion 93b is held by the frame portion 92b.

  The clip 93 is inserted into the clip holding hole 92 a of the hinge 92, and the shaft 92 e of the hinge 92 is fitted into the bearing hole 91 b of the grip body 91, whereby the hinge 92 and the clip 93 are assembled to the grip body 91. Thereafter, as shown in FIG. 10, the tip of the clip 93 is inserted into a mounting hole 97a formed in the vehicle body side panel 97, and the cap 94 is press-fitted into the clip 93 from the clip holding hole 92a. Thereby, the assist grip 9 is attached to the vehicle body.

  However, the arm 92d of the hinge 92 is deflected by applying a load in a direction close to each other, so that the shaft 92e formed on the arm 92d slides on the inner wall of the recess 91a of the grip body 91. The shaft 92e is fitted into a bearing hole 91b formed in the inner wall of the recess 91a. Since the arm portion 92d is fixed to the frame portion 92b, the pair of arm portions 92d is equivalent to the interposition of a stick and maintains a predetermined interval. For this reason, the frame portion 92b does not bend, and the outer width of the arm portion 92d is narrowed only by bending of the tip portion of the arm portion 92d. Therefore, if the arm portion 92d is bent to the extent that it can be fitted into the bearing hole 91b, it is necessary to apply a great load to the arm portion 92d, and the assembling workability is poor.

  In view of this, Patent Documents 1 and 2 disclose a technique that does not require an excessive load when the arm portion is fitted into the bearing hole. FIG. 6 of Patent Document 1 shows an angle for guiding the hinge (14) to the bearing hole (20) facing the bearing hole (20) facing the bearing hole (20) facing the clip holding hole (18). It is disclosed to form a grooved lead-in or track (22) with a bevel.

Further, FIG. 4 of Patent Document 2 discloses that the arm portion (36) is directly injection-molded in the bearing hole (38). That is, a grip body is inserted into a mold, and a hinge having an arm portion is injection-molded. Thus, the arm portion (36) is accommodated in the bearing hole (38) without play and the arm portion (36) is accommodated without being detached from the bearing hole (38).
Japanese Patent Laying-Open No. 2005-138823 (FIG. 6, paragraph number “0008”) Japanese Patent Laying-Open No. 2005-35538 (FIG. 4, paragraph number “0011”)

  However, in patent document 1, there exists a possibility that an arm part may come out from a bearing hole (20) along a lead-in or a track | truck (22). Moreover, in patent document 2, when the shape of a hinge is complicated, a grip main body may be inserted and a hinge may not be injection-molded.

  The present invention has been made in view of such circumstances, and is excellent in assembling workability when the shaft provided in the hinge is fitted into the bearing hole provided in the grip body, and the shaft comes out of the bearing hole. It is an object of the present invention to provide an assist grip that can prevent the above-described problem.

The present invention is a grip body having a longitudinal shape, a recess formed at both ends, and a pair of bearing holes formed in mutually facing portions of the peripheral wall of the recess;
A frame portion housed in the recess and having a clip holding hole, a pair of arm portions extending from a pair of extending base portions spaced apart from each other at a predetermined interval in the frame portion, and a pair of arm portions. A hinge having a shaft pivotally supported by the pair of bearing holes;
In an assist grip having a clip in which a tip end portion is inserted into the clip holding hole and a base end portion is held by the frame portion,
The pair of arms are disposed in the recess,
One of the pair of shafts is a fixed shaft provided integrally with the arm portion, and the fixed shaft is fitted to one of the pair of bearing holes from the inner peripheral wall side of the recess,
The other of the pair of shafts is a shaft member separate from the arm portion, and the shaft member is inserted into an insertion hole formed in the arm portion, and one end side of the shaft member is A retaining member that is fitted to the other of the pair of bearing holes from the inner peripheral wall side of the recess, and the other end is interposed between the one arm portion provided with the fixed shaft. They are in contact with each other (claim 1).

  According to the present invention, one of the pair of shafts is a fixed shaft provided integrally with the arm portion, and the other of the pair of shafts is a shaft member separate from the arm portion. For this reason, when assembling the hinge to the grip body, after the fixed shaft provided integrally with one arm portion is fitted into one bearing hole of the grip body, the insertion hole of the other arm portion is inserted into the other arm portion. Place on the axis of the bearing hole. Thereafter, the shaft member is inserted into the insertion hole and the other bearing hole. For this reason, when assembling the hinge to the grip body, there is no press-fitting work, and the assembling workability is excellent.

  One end side of the shaft member is fitted into the other bearing hole, and the other end side is in contact with a retaining member interposed between one arm portion provided with the fixed shaft. For this reason, the shaft member does not fall out of the insertion hole. Further, the retaining member suppresses the pair of arm portions from being bent in a direction approaching each other. Therefore, the fixed shaft and the shaft member provided in the pair of arm portions are also prevented from coming out of the pair of bearing holes, respectively.

  Embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is an exploded perspective view of an assist grip according to the present embodiment. The upper side of each member shown in FIG. 1 is called “upper” and the lower side is called “lower”. As shown in FIG. 1, the assist grip 10 has a grip body 1, a hinge 2, a clip 3, and a cap 4.

  FIG. 3 is a perspective view of the hinge as viewed from below. As shown in FIG. 3, the hinge 2 has a frame portion 22 that surrounds a rectangular clip holding hole 21 into which the clip 3 is inserted. The upper end (lower side in FIG. 3) of the rectangular frame portion 22 is a portion covered with the cap 4, and has a shape along the inner peripheral surface of the cap 4. That is, among the four peripheral walls 22a, 22b, 22c, 22d facing the four directions of the frame portion 22, the three peripheral walls 22a, 22b, 22c have the same vertical width, and the other one peripheral wall 22d has three. The width in the vertical direction is narrower than the two peripheral walls 22a, 22b, 22c. Both ends of the peripheral wall 22b of the frame portion 22 are extended base portions 22e from which a pair of arm portions 23 are extended.

  The pair of arm portions 23 is extended from the extending base portion 22e in a direction away from the peripheral wall 22b. Between the pair of arm portions 23, an outer wall 20 that houses a damper 5 and a spring 6 described later is provided. The pair of arm portions 23 has a facing surface 23a facing each other and a back surface 23b opposite to the facing surface 23a. A fixed shaft 23c projects from one back surface 23b of the pair of arm portions 23. An insertion hole 23e is formed in the other arm part 23, and the shaft member 8 separate from the arm part 23 is inserted into the insertion hole 23e.
