The present invention relates to an improved pin device which comprises a pinning means (hereinafter referred to as A means) and a fastening means (hereinafter referred to as B means). The present invention provides a fastener that does not loosen easily and slip off like an ordinary pin and can function both as a pin and a clip.
A mounting device representing a combination paper clip and a pointed mounting member therefor, designed to be appended to a bulletin board or other mounting surface. This novel mounting device is of elongate configuration and involves a resilient wire having a plurality of bends therein, with selected ones of the bends defining a pair of elongate, coplanar loops. A first of the loops is slightly larger than the second of the loops, with the side portions of the second loop residing essentially within the confines of the side portions of the first loop. An article-receiving location is defined between the loops, adjacent one end of the device. The article-receiving location is adapted for receiving a relatively flat item inserted between the loops, with the inherent resilience of the wire tending to hold the flat item in a secure manner. One of the side portions of the first loop serves as the mounting means for a pressure-applying member located at an essentially opposite end of the mounting device from the article-receiving location. A pointed mounting member is operatively associated with the pressure-applying member and disposed at essentially a right angle thereto. The pointed mounting member is of a length to extend beyond the plane of the loops and by virtue of its position, when pressure is applied to the pressure-applying member, the pointed mounting member is caused to penetrate the mounting surface and be retained therein.
6641105 - Hanger - Owned by 3M Innovative Properties Company (St. Paul, MN)
A hanger comprising a base having a supported surface adapted to be positioned along a generally vertical surface, and an elongate peg having one end mounted on the base with a portion of the peg projecting from an outer surface of the base opposite its supported surface generally at a right angle with respect to the supported surface of the base. The peg has an axially extending surface portion adapted to be positioned uppermost when the supported surface of the base is positioned along a generally vertical surface, which axially extending surface portion restricts free movement axially of the peg of sheets of paper around and hanging on the peg. That axially extending surface portion can be defined by a layer of adhesive on the peg or by closely spaced sharp edges on the peg. Such sharp edges could be on screw threads around the peg, ridges extending transversely across the peg, serrations formed on the peg, or by abrasive granules adhered along the peg.
