发明名称 Gooseneck lamp and magnifier with improved clamp assembly
摘要 A gooseneck lamp assembly for clamping to a table includes a base member with a clamp portion at one end and a mounting portion for the gooseneck elements at the other end and a pivotable floating clamp with a vertically extending leg portion slidably seated in a slot in the clamp portion of the base member and a clamping leg portion extending forwardly therefrom beneath the clamp portion of the base member. The shank of a clamping bolt extends through the clamp portion of the base member and the clamping leg portion of the clamp, and a knob is threadably engaged on the portion of the shank extending above the base member so that rotation of the knob will effect pivoting of the free end of the clamping portion towards and away from the base member. A coil spring is provided about the shank of the clamping bolt between the clamp portion and the clamping leg portion to bias the free end of the clamping leg portion away from the clamp portion and thereby facilitate moving the clamping elements over the edge of the table. Bearing means is desirably provided between the knob and the base member to minimize friction, and a friction element is provided on the lower surface of the base member to minimize slipping on the associated table and to prevent marring of its surface.
