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.
Claims13
A lamp swivel mountable between a lamp base and a lamp body, said lamp body having an associated light-generating means, so that said lamp body together with its associated light-generating means may be swivelably pivoted and rotated on linear support means and about an axis, said axis being the principal axis of the lamp swivel, which comprises.
- (a) a first member, said first member having a first central axis, a body disposed along said first central axis, and a dependent cylindrical extension, said extension being coaxial with said first central axis, said first central axis lying along said principal axis, said first member body being provided with means to receive one end of said linear support means, said linear support means extending from said one end to an other end connection to said lamp body,
- (b) pin means, said pin means extending laterally outwards from the outer surface of said extension, and
- (c) a second member, said second member having a second central axis and a body disposed along said second central axis, one end of said second member body having a cylindrical recess, said body recess being coaxial with said second central axis and having a diameter slightly greater than the diameter of said extension of said first member, so that said extension is contiguously insertable into said recess, the lateral surface of said recess having a slot and a circular groove, said surface slot extending from one end of said second member body to said circular groove in the surface of said recess, said groove being coaxial with said second central axis, so that when said extension is inserted into said recess, at least a portion of said first central axis is coaxial with said second central axis, said pin means being then receivable through said slot and into said groove, whereby said first member is detachably attached to said second member, and said first member is at least partially rotatable about said first central axis, while said second member either remains stationary or concomitantly rotates about said second central axis, said second central axis lying along said principal axis, said second member body being detachably attachable to means extending to said lamp base.
