Abstract: A fastener including a body and a locking pin is disclosed. The fastener body includes an apertured base and conjoined flexible arms extending from the base and defining a passage therebetween. The locking pin is arranged for movement relative to the fastener body along a predetermined path of travel and within the aperture and the passage defined by the flexible arms. The locking pin has a predriven position and an extended driven position. A resilient lock is provided in conjunction with the fastener body and resiliently extends into the predetermined path of travel of the pin, when said locking or drive pin is in the predriven position, thereby inhibiting movement of said locking pin toward said driven position. The lock remains in position to inhibit inadvertent linear shifting of the driving pin until the flexible arms are inserted through an opening in an article with which the fastener is arranged in operable association.

Abstract: The present invention is a wall anchor having a novel finger configuration. This wall anchor has a head and barrel portion with a bore extending therethrough and laterally expandable fingers in general alignment with the bore. Instead of a straight channel, a channel having curved portions separates the fingers. The curved portions of the channel define ramp surfaces that at least partially extend into the path of a securing member created by the bore. Thus, when a securing member, such as a bolt, pin, screw, nail or similar object is inserted into the bore to secure the wall anchor to the wall, the securing member contacts the two ramp surfaces, separating the fingers. As the fingers separate, a portion of the fingers near the ramp surfaces deform such that the ramp surfaces rest on an outer portion of the securing member, thus providing a securing force for connecting the wall anchor to the wall and relieving stress on the area at which the fingers are connected to the barrel.

Abstract: The fastener includes a pin and a body. The pin includes longitudinal grooves which communicate with partially threaded grooves which traverse the circumference of the shank by an integer multiple of 180°. Retention fingers engage the longitudinal grooves in the pre-installed configuration and allow straight-line insertion of the pin into the body. The retention fingers are then urged outwardly by the walls of the partially threaded grooves and then snap engage into subsequent portions of the partially threaded grooves thereby preventing straight-line removal of the pin. The pin, however, can be subsequently removed by threaded rotating the pin until the retention fingers engage the longitudinal grooves. Thereafter, the pin can be manually removed by a straight-line motion.

Abstract: A clip is formed of a male and a female members, and can take a temporarily fastened state by inserting an inserting shaft of the male member into an inner side of leg pieces of the female member and a finally fastened state by further inserting the inserting shaft. In the finally fastened state, the leg pieces are widely opened and fixed to the inserting shaft. The clip includes engaging projections, as a correcting device, disposed between the adjacent leg pieces facing each other and allowing the widely opened leg pieces to move inwardly when the male member is moved to the temporally fastened state. Thus, the clip can be easily fastened and removed.
