Abstract: An example target pin is disclosed having a body for a removable shaft. The body has a base and a support structure configured to retain the removable shaft substantially perpendicular to the base when the removable shaft is assembled in the support structure of the body. The removable shaft is assembled in the body and is then ready for use by press it through a target into a target backing to hold the target securely in place on the target backing during archery or other target shooting.

Abstract: A fastening device designed to be suitably used with needle detectors. The fastening device does not trigger alarms from needle detectors. A fastening device comprises a frame having a plurality of metallic strips coupled contiguously to form an enclosure. The plurality of metallic strips are selected from a group of metallic materials having different ferromagnetic responses and at least two of said selected metallic strips have different ferromagnetic responses. Thereby when said fastening device is attached to a garment and said garment is passed through a needle detector, said fastening device does not trigger a false alarm from said needle detector. A tongue is further attached to the metallic strip.

Abstract: In accordance with at least one exemplary embodiment, a pushpin retaining device is disclosed. An exemplary pushpin retaining device can include a resilient, elongated pin that can have a first end portion for puncturing and a second end portion. A grip foot can be operatively associated with the second end portion of the pin. Alternatively, a cut edge can be on the second end portion of the pin. A method of retaining objects without object puncture can include providing a pushpin retaining device. The method can also include puncturing a support surface with an end of the pin of the pushpin device and pressing a portion of an object against the support surface with the grip foot or cut edge, respectively.

Abstract: A self-fastening and replaceable fastener for attaching a button to at least one layer of fabric. The fastener includes a coil. The button has at least one sew throughbore. The coil is helically-shaped so as to form a thread pattern for treatably puncturing through at least one of the at least one layer of fabric. The coil has a head and a tip that passes through an associated sew throughbore in the button and treatably punctures through the at least one layer of fabric, until such time as the head of the coil, which is widened, seats on the button.
