  • Patent number: 11965536
    Abstract: A clip for attaching an attaching article to an object member may include an engagement claw configured to engage an attaching hole formed in the object member. The clip may also include a slide body configured to retainably hold the engagement claw on the attaching article and configured to slide the engagement claw with respect to the attaching article so as to project and retract the engagement claw. The clip may also include an elastic body configured to apply a restoring force to the engagement claw when the engagement claw slides from a projected state to a retracted state with respect to the attaching article, so as to provide a biasing force to return the engagement claw toward the projected state.

  • Patent number: 11912482
    Abstract: A clip comprising a connecting base including a bolt introduction hole that is configured such that a bolt member formed on an object member is introduced thereinto. The connecting base includes flexible engagement strips formed on an inner surface thereof and having pressing blocks. The pressing blocks respectively include engagement claws formed on proximal end portions of inner surfaces thereof. The engagement claws engage the predetermined portions of thread groove of the bolt member, so that the connecting base is connected to the object member. In a connected condition of the connecting base, when the engagement claws are disengaged from the predetermined portions of the thread groove due to an extraction force, edge portions formed on distal end portions of the inner surfaces of the pressing blocks engage different portions of the thread groove of the bolt member.

  • Patent number: 11359655
    Abstract: A clip may include an attachment base, and an anchor including a pillar formed on the attachment base and a pair of engagement legs formed on the pillar. When the anchor is inserted into an attaching hole formed on an object member, the anchor is held in the attaching hole, so that the clip is attached to the panel. The clip further includes a rotation preventive mechanism that is configured to prevent the pillar from rotating relative to the attaching hole in a condition in which the anchor is held in the attaching hole. The rotation preventive mechanism includes a pair of projections formed on one end portion of the pillar, and at least one projection formed on another end portion of the pillar. The pair of projections formed on one end portion of the pillar respectively have through bores formed thereon.
