Abstract

A clip includes a grommet having a projecting portion and a plurality of leg portions extending from the projecting portion, and a shaft member including a head portion, and a shaft portion extending from the head portion, and inserted into an inside of the leg portions to laterally expand the leg portions. The clip is switchable between a lock position to expand the leg portions laterally, and an unlock position where the shaft member is further pushed to return the leg portions to an original condition. Each leg portion includes a leg-side convex portion, a convex-portion wall face, and a guide portion. The shaft portion includes a shaft-side convex portion engaging the leg-side convex portion, a concave portion provided between the shaft-side convex portion and the head portion, and engaging the leg-side convex portion to return the leg portion to the original condition, an abutment portion, and a release portion.

First claim

What is claimed is:

1. A clip comprising:
a grommet having a projecting portion, and a plurality of leg portions diametrically expandably extending from the projecting portion; and
a shaft member including a head portion, and a shaft portion extending from the head portion, and being configured to be inserted into an inside of the leg portions from a through hole provided in the projecting portion so as to expand a diameter of the leg portions,
wherein the clip is configured to be switchable between a lock position where the shaft member is pushed into the grommet for a predetermined amount to expand the diameter of the leg portions, and an unlock position where the shaft member is further pushed in so as to return the leg portions to an original condition,
each leg portion includes a leg-side convex portion provided on an inner side of the plurality of leg portions; a convex-portion wall face extending from a leg-portion tip side to the leg-side convex portion; and a guide portion situated adjacent to the leg-side convex portion perpendicular to a longitudinal direction of the leg portion and extending to the leg-portion tip side, the guide portion having an extending tip inclined to the inside of the leg portion for easily inserting into an attachment hole for insertion of the leg portion, and
the shaft portion includes a shaft-side convex portion engaging the leg-side convex portion to expand the diameter of the leg portion; a concave portion provided between the shaft-side convex portion and the head portion, the concave portion, when engaging the leg-side convex portion, returning the leg portion to the original condition from expansion thereof; an abutment portion provided between the shaft-side convex portion and the concave portion for the convex-portion wall face; and a release portion for the guide portion, situated adjacent the shaft-side convex portion perpendicular to a longitudinal direction of the shaft portion.

2. A clip according to claim 1 , wherein the grommet includes the projecting portion for abutting against a periphery of a first attachment hole bored in an attaching member; and the plurality of leg portions diametrically expandably extending from the projecting portion, and inserted into the first attachment hole and a second attachment hole bored in an attached member attaching or connecting the attaching member, and
the shaft member includes the head portion; and the shaft portion extending from the head portion, and inserted into the inside of the leg portions from the through hole provided in the projecting portion to expand the diameter of the leg portions so as to be pushed against a hole wall side of the second attachment hole.

3. A clip according to claim 1 , wherein the attachment hole is a circular hole, and the leg portions are formed by two facing each other.

4. A clip according to claim 3 , wherein each leg portion is provided such that the leg-side convex portion and the guide portion are respectively provided right-and-left alternately, and the shaft portion alternately provides release portions corresponding to guide portions on a different side, and a depth of the release portion reaches an approximately intermediate position of a thickness of the shaft portion.

5. A clip according to claim 1 , wherein the concave portion is formed in the through hole.

6. A clip according to claim 1 , wherein the shaft member includes a protruding portion extended in an axial direction of the shaft portion to restrict a relative rotation of the grommet.

7. A clip comprising:
a grommet having a projecting portion, and a plurality of leg portions diametrically expandably extending from the projecting portion; and
a shaft member including a head portion, and a shaft portion extending from the head portion, and being configured to be inserted into an inside of the leg portions from a through hole provided in the projecting portion so as to expand a diameter of the leg portions,
wherein the clip is configured to be switchable between a lock position where the shaft member is pushed into the grommet for a predetermined amount to expand the diameter of the leg portions, and an unlock position where the shaft member is further pushed in so as to return the leg portions to an original condition,
each leg portion includes a leg-side convex portion provided on an inner side of the plurality of leg portions; a convex-portion wall face extending from a leg-portion tip side to the leg-side convex portion; and a guide portion situated adjacent to the leg-side convex portion and extending to the leg-portion tip side, the guide portion having an extending tip inclined to the inside of the leg portion for easily inserting into an attachment hole for insertion of the leg portion,
the shaft portion includes a shaft-side convex portion engaging the leg-side convex portion to expand the diameter of the leg portion; a concave portion provided between the shaft-side convex portion and the head portion, the concave portion, when engaging the leg-side convex portion, returning the leg portion to the original condition from expansion thereof; an abutment portion provided between the shaft-side convex portion and the concave portion for the convex-portion wall face; and a release portion for the guide portion, and
the shaft member includes an elastic piece provided in the shaft portion, and having a fitting state of fitting into an edge portion of the through hole on a projecting portion side in an engagement state between the leg-side convex portion and the shaft-side convex portion, and when the shaft member is pushed into the grommet further, the shaft member is adapted to pass the through hole accompanied by an elastic deformation to release the fitting of the fitting state.
