A base member of a push pin is formed by casting or molding, and a pin is inserted pointed end first into a hole in the base member and forced through the base member until the end opposite thereof lies below the surface of the base member. The material of the base member is then flowed over the end of the pin, by mechanical or heat techniques, to form a substantially complete layer over the end of the pin within the base member. The pins preferably extend at an acute angle to a flat surface of the base member. The push pin may have pins extending from opposite surfaces thereof, a loop shaped projection adapted to be affixed to a wire, or a hinge separating the base member into a hook portion and a portion carrying one or more pins. The push pin may have a contoured base member to facilitate the affixing of a picture wire to a hook formed on the base member. In another embodiment the push pin has a projection on the side thereof through which the pin extends, the projection having a rounded contour adjacent the pin, a radially outer surface, and an intermediate axially extending section between the rounded surface and the radially outer portion. The push pin may be formed with a pivoted lever, to serve as a wire clamp. For picture hanging purposes, the push pin may include a pair of pins extending from opposite sides of an elongated member and through projections, the elongated member having a saw tooth edge, with the planes of the saw tooth edge and the side of the elongated member adjacent thereto extending at an angle corresponding to portions of a nail extending at an angle in the wall, in order to facilitate the hanging of a picture on the wall.
A push pin picture mount adapted to be mounted by means of pins to the back of a picture and to engage a wall fastening device for holding the picture to a wall, said picture mount comprising an elongated support member having first and second opposite sides joined by first and second opposite edges, a projection on each end of said member extending from said first side, a pin having a first end embedded in said member at each end and a sharpened and extending from the respective projection in a direction away from said first side, whereby said sharpened ends may be inserted in a picture with said projections holding said member spaced from the frame of said picture, the ends of said projections away from said member defining a first plane, the portion of said first side adjacent said first edge lying in a second plane at an acute angle to said first plane, with the distance between said first and second planes increasing away from said first edge, said first edge having a sawtooth shape, with transverse lines across said first edge being at a determined acute angle with respect to said first plane.
