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. For example, as shown in FIG. 7, the assist grip 9 includes a long grip body 91, a hinge 92, a clip 93, and a cap 94. As shown in FIG. 8, 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. 7, the tip of the clip 93 is inserted into the 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.

  Therefore, Patent Documents 1 and 2 disclose techniques that do 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 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 it is an object to provide an assist grip excellent in assembly workability when a shaft provided on a hinge is fitted into a bearing hole provided in a grip body. And

  The present invention has a longitudinal shape, a concave body formed at both ends, and a grip body having a pair of bearing holes formed at opposing portions of a peripheral wall of the concave portion, and is accommodated in the concave portion and has a clip holding hole. A hinge having a frame portion and a pair of arm portions having shafts extending from a pair of extending base portions spaced apart from each other at a predetermined interval and pivotally supported in the pair of bearing holes; In an assist grip having a clip in which a tip end portion is protruded into the clip holding hole and a base end portion is held by the frame portion, the frame portion is divided between the pair of extended base portions. (Claim 1).

  According to the above configuration, the frame portion of the hinge is divided between the extended base portions from which the arm portions extend. For this reason, a pair of arm part is hold | maintained by the divided | segmented frame part, and it will be in the state from which the stick was lost between a pair of arm part. Therefore, the frame portion can be bent in a direction approaching between the extended base portions by a slight load. Therefore, when the shaft provided on the arm part is fitted into the bearing hole of the grip body, the arm part not only bends in the proximity direction by applying a slight load in the direction in which the arm parts approach each other. The frame portion also bends in the direction in which the extended base portions are close to each other. Therefore, it becomes easy to fit the shaft into the bearing hole, and the workability when the hinge is assembled to the grip body is improved.

  The hinge extends in parallel with the peripheral wall between the extended bases of the frame part, divides the clip holding hole into two, and is fixed at both ends to the frame part and inserted into the clip. It is preferable to have a contact rib, and the corresponding contact rib is divided at an intermediate portion between both ends fixed to the frame portion.

  According to the above configuration, when the clip is press-fitted into the mounting hole formed in the mounting member with the abutment rib inserted into the clip, the clip is pushed back at the periphery of the mounting hole and comes out of the hinge. Is suppressed. This abutment rib is divided at an intermediate portion between both ends fixed to the frame portion. For this reason, the contact rib does not hinder the bending of the frame portion. Therefore, when a load is applied to the arm portion, the entire frame portion can be easily bent.

  It is preferable that a retaining member is provided between the pair of arm portions to prevent the pair of arm portions from bending in a direction approaching each other.

  According to the above configuration, the retaining member that suppresses the pair of arm portions from being bent in the direction in which the pair of arm portions approach each other is provided between the pair of arm portions. For this reason, it can suppress effectively that the axis | shaft provided in the arm part slips out from a bearing hole.

  In the assist grip according to the present invention, the frame portion provided on the hinge is divided between the extended base portions from which the arm portions extend. For this reason, there is no hard stick between the arm portions, and the load required to bend between the extended base portions of the frame portion is reduced. Therefore, it is excellent in assembling workability when the shaft provided in the hinge is fitted into the bearing hole provided in the grip body.

  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 FIGS. 2 and 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 peripheral wall 22b between the extended base portions 22e is divided in the vertical direction at the center portion, and is constituted by two divided portions 22f and 22g. A slit 22h having a predetermined width is interposed between the two divided portions 22f and 22g. The width of the slit 22h is such a size that the divided portions 22f and 22g do not interfere with each other when the arm portions 23 are brought close to each other so that the arm portion 23 is accommodated in the concave portion 11.

  The pair of arm portions 23 is extended from the extending base portion 22e in a direction away from the peripheral wall 22b. 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, and a shaft 23c projects from the back surface 23b.

Therefore, it becomes easy to fit the shaft 23c into the bearing hole 12, and workability when the hinge 2 is assembled to the grip body 1 is improved.

  Further, the hinge 2 has a contact rib 24 fixed to the inner peripheral surface of the frame portion 22 so as to cross the clip holding hole 21. The contact rib 24 is also divided at the center. For this reason, the contact rib 24 does not hinder the bending of the frame portion 22. Therefore, when a load is applied to the arm portion 23, the entire frame portion 22 can be easily bent.

  A core member 61 around which the damper 5 or the spring 6 is wound is interposed between the pair of arm portions 23. For this reason, it is suppressed that a pair of arm part 23 bends in the direction which adjoins mutually. Therefore, it is possible to effectively suppress the shaft 23 c provided on the arm portion 23 from coming out of the bearing hole 12.

  In the present embodiment, a core member 61 around which the damper 5 or the spring 6 is wound is provided between the pair of arm portions of the hinge 2 as a retaining member. If it is a member which suppresses peeling, it will not specifically limit.

  In the present embodiment, not only the clip 3 but also the leg portion 4b of the cap 4 is inserted into the clip holding hole 21 of the hinge 2, but the assist grip is assembled to the vehicle body side panel without using the cap 4. In the clip holding hole 21, only the clip 3 is inserted.
