ABSTRACT:
A lamp swivel composed of two main coaxial members, which are at least partially rotatable relative to each other. An inner pin extends from one member to a circular inner groove in the other member, the groove being coaxial with the members. However, the other member, usually composed of a metal such as brass, copper or aluminum which may be anodized, is coined so as to prevent egress of the pin from the groove. Thus the two members are semi-permanently attached to each other and can rotate, by less than 360 degrees, relative to each other. The invention is especially applicable to provide an articulated lamp mounting for a swing arm lamp or the like, the lamp swivel being a swivel connector or coupling means which provides an articulated mounting attachment for the lamp.
