Abstract: One embodiment provides a mounting structure including a hook member to be mounted on a mount member, and a mounting member. A base part of the hook member protrudes from the front side of the mount member. In the mounted state, a locking part of the hook member locks with a back rim of a mounting hole. An operation part of the mounting member is operated during the mounting on the mount member. An engaging part of the mounting member can engage with the locking part at the back side of the mount member. The mounted state is achieved by sliding, via an operation applied to the operation part, the mounting member substantially parallel to a front surface or a back surface of the mounting hole, such that the engaging part engages with the locking part.

Abstract: A two piece retainer assembly is used for positive retention of an associated vehicular floor mat to the vehicle's floor surface. The retainer assembly works in conjunction with a hook-like fastener permanently mounted to the vehicle's floor surface. The two piece retainer assembly comprises (a) an annular collar for positioning in a hole in the floor mat from an underside, and (b) a locking cover coupler for positioning in the hole of the floor mat from an upper side. The annular collar and locking cover coupler are forced together to trap the floor mat. The annular collar has a vertical upwardly extending wall forming an opening and a horizontally radially extending flange connected to the vertical wall. The locking cover coupler has a base plate with a vertical downwardly extending wall forming an opening and dimensioned to receive the vertical upwardly extending wall of the annular collar in frictional engagement. At least two vertically extending latching tabs extend from the base plate.

Abstract: A snap fastener having a detachment directionality. The fastener includes a portion for minimizing the gap between the male and female snaps (1, 4). The portion is, for example, a small protrusion (17) established on the side of the neck (13) opposite the engagement edge (16),or a protrusion (47) established on the side of the female snap.
