ABSTRACT:
A desk set with integrally formed swivel clamping means which can be injection-molded without use of a cam-action mold. The swivel clamping means comprises four semicylindrical clamping members (28) inclined toward each other to form a socket for a ball (26) attached to an accessory support stem (24) for holding a pen (30), a clock (32), or the like. To increase friction between the ball (26) and the socket, the socket clamping members (28) each include an inwardly pointing lip (46) and the surface of the ball (26) is covered with alternating slots (38,42) and ridges (40,44).
