  • Publication number: 20110197405
    Abstract: A clip may include a main body and a pin member. In the clip, an engagement condition of the anchor to an attaching hole formed in a plate member can be maintained by inserting an elastic shank portion of the pin member into the anchor of the main body. The elastic shank portion inserted into the anchor is received by a stopper of the anchor, so that the pin member can be locked in a temporary insertion position. An interfering portion of the elastic shank portion is exposed to an exterior portion the anchor. When the anchor is inserted into the attaching hole, the interfering portion of the elastic shank portion interferes with a periphery of the attaching hole, so that a condition in which the pin member is locked in the temporary insertion position can be released.

  • Publication number: 20110167590
    Abstract: For receiving and stopping movement of a movable member approaching to a fixed member in order to absorb impacts, a cushion clip includes a clip body capable of being mounted by inserting into a mounting hole formed in one of the fixed member and the movable member, and a cushion body capable of absorbing impacts by resilient deformation. The clip body made of rigid resin material and the cushion body made of soft resin material are integrally joined to each other at a mutual joint portion by a two-material molding process. At the mutual joint portion, the clip body includes a base portion entering into inside of the cushion body, and a concave-convex configuration, such as ribs, is provided to the base portion for increasing a contact area with the cushion body.

  • Publication number: 20110072624
    Abstract: A clip may include an anchor portion having a plurality of flexible strips and at least one support strip. Each of the flexible strips is integrally connected to the at least one support strip only via a connecting portion corresponding to a distal end portion of the anchor portion and a connecting portion corresponding to a proximal end portion of the anchor portion. When the anchor portion is pushed into an insertion hole formed in a subject member, the anchor portion is inserted into the insertion hole while each of the flexible strips are flexed toward a longitudinal axis of the anchor portion. Each of the flexible strips is formed such that the difference between a second moment of area of the anchor distal end side connecting portion and a second moment of area of the anchor proximal end side connecting portion is 0-15%.
