Abstract
A push pin is provided for securing pieces of paper, photographs, postcards, posters and similar items to a support surface without puncturing or otherwise damaging the item. The push pin includes a body portion and a pin. In a preferred embodiment, the body portion defines a raised circumferential portion to facilitate insertion and withdrawal of the push pin. In one embodiment, the push pin includes a linear spring extending from the body portion to a distal end. Advantageously, the distal end of the linear spring at least partially contacts the item and urges the item towards the support surface. In an alternate embodiment, the body portion defines a groove defining an elongate member extending from the body portion to a distal end. Advantageously, the distal end of the elongate member at least partially contacts the item and urges the item towards the support surface without piercing or otherwise damaging the item. In still another embodiment, the body portion defines a recessed surface for at least partially contacting the item and urging the item towards the support surface such that the item is secured between the said recessed surface and the support surface.
