Description

  The present invention relates to an assist grip that is attached to a ceiling surface or the like in an automobile interior, and more particularly to an assist grip that can be easily fitted and assembled with a hinge portion in a grip body.

  An assist grip is attached to the ceiling surface in the automobile room so that the passenger can support the body in the room. As this type of assist grip, there is a structure in which recesses are formed on both sides of the grip body, a hinge part is rotatably mounted in the recess, and the grip body is rotatably mounted via the hinge part. It is installed in various automobiles.

  When an assist grip having a hinge portion is normally attached to the recess of the grip body, a metal shaft is drilled from the outside of the grip body into the side wall of the recess with the hinge portion being disposed at a fixed position in the recess. While being press-fitted into the provided shaft hole, the hinge portion is inserted into the concave portion by being inserted into the bearing portion of the hinge portion. For this reason, separate parts such as a metal shaft are required, the assembly work when press-fitting the metal shaft is complicated, and the end of the metal shaft is exposed outside the assist grip, which deteriorates the appearance of the assist grip. was there.

Therefore, conventionally, in Patent Document 1 below, an assist grip has been proposed in which a hinge portion is fitted into a recess on both sides of a grip body so as to be rotatably mounted.
JP 2005-138823 A

  The assist grip has support pieces projecting on both sides of the hinge body, bosses projecting on both ends of the support piece, a shaft hole is provided in the recess of the grip body, and the shaft hole is provided. A groove is formed on the inner wall surface, and the hinge is pivoted in the recess of the grip body by bending the support piece and pushing the boss into the shaft hole while sliding in the groove. To do.

  However, this conventional assist grip has a structure in which the bosses on both sides are pushed into the respective shaft holes in the recesses of the grip body while simply bending the support pieces projecting from the hinge body, so that the hinge body has a large amount. There was a problem in assembly workability because it was necessary to apply a load. In addition, as a measure to improve the assembly workability, it was considered to shorten the length of the boss part. However, if the length of the boss part is shortened, the lapping margin between the boss part and the shaft hole becomes insufficient, and the assist There is a possibility that the strength required when using the grip is insufficient.

  The present invention has been made in view of the above points, and the hinge portion can be easily assembled in the concave portion of the grip body without using a metal shaft, and the strength necessary for use can be reliably maintained. It is an object to provide an assist grip that can be used.

In order to achieve the above object, the assist grip according to claim 1 of the present invention is provided with hinge recesses on both sides of the base portion of the grip body, and a pair of hinge portions are rotatably fitted in the hinge recesses. In assist grip,
Boss holes are formed in the side walls on both sides of the recess for the hinge, an outer support piece projects from the lower part of the hinge body of the hinge part, and an inner support piece projects from the inside of the lower part of the hinge body. The support piece is formed to be thicker than the outer support piece, and an inner boss that can be fitted into the boss hole protrudes from the inner support piece, and the boss hole is formed outside the outer support piece. An outer boss that can be fitted into the inner support piece, a notch groove is provided in the upper portion of the base portion of the inner support piece, a notch portion is provided in a lower end portion of the outer boss, and the inner boss and outer boss of the hinge portion are When the hinge recess is fitted into the boss hole, the edge of the hinge recess enters the notch groove, and the inner boss and the outer boss are in contact with the edge of the hinge recess while the notch of the outer boss slides on the edge of the hinge recess. It is characterized by being fitted into the boss hole.

  According to the present invention, when the hinge portion is rotatably fitted in the hinge recess, the outer boss is placed outside the hinge recess while the inner boss is placed in the inside boss hole. , The edge of the hinge recess enters the notch groove, the notch of the outer boss slides into contact with the edge of the hinge recess, and the outer support piece with a smaller thickness is bent while the outer boss is in the boss hole. The hinge portion can be rotatably mounted in the hinge recess with a relatively simple operation. In addition, when using the assist grip, the load when the user pulls the grip is mainly applied to the inner boss and the inner support piece in the pair of hinges. The projecting inner boss can reliably support the load, and the outer boss is notched at the lower end of the tip, and the upper part of the outer boss is inserted into the boss hole with a sufficient wrap amount. Since the load is supported by the upper portion of the outer boss having no portion, the load on the grip body during use can be reliably held between the inner boss and the outer boss of the hinge portion.

  According to a second aspect of the present invention, in the assist grip according to the first aspect of the present invention, in the state where the outer boss of the outer support piece and the inner boss of the inner support piece are fitted into the boss hole of the hinge recess, A support member is inserted between the lower inner support piece and the outer support piece to support both support pieces from the inside.

  The support member can be an axial support member that supports the torsion coil spring and is inserted between the inner support piece and the outer support piece to support the torsion coil spring. The grip body is biased to the non-use position with respect to the hinge portion. Moreover, an oil damper can be used as a support member as in the fourth aspect, and the oil damper acts to decelerate the rotation speed when the assist grip is rotated with respect to the hinge portion.

  According to the invention of claim 2, when the load of the grip body is applied to the inner boss, the outer boss, the inner support piece and the outer support piece in use, the inner support piece and the outer support piece are each easily bent inward. Inward bending is prevented by the support member, maintaining a good fit between the inner boss of the hinge part, the outer boss of the hinge part and the boss hole of the recessed part for the hinge, ensuring the load applied to the grip body during use Can be held in.

  According to the assist grip having the above configuration, since the metal shaft is not inserted into the base of the grip body from the outside, the appearance of the grip body is not deteriorated, and the hinge portion can be easily assembled in the hinge recess of the grip body. In use, the load applied to the grip body can be reliably held via the inner boss, outer boss, inner support piece, and outer support piece of the pair of hinge portions.
