Abstract
A lamp assembly is disclosed which includes a base, a lamp arm mounting adapter on the base for pivotally mounting a lamp arm thereto, with the lamp arm itself having a first pair of hollow support tubes mounted on the adapter for pivotal movement on a vertical axis in a generally horizontal plane and having a arm support pivotally mounted on their opposite ends for pivotal movement on a vertical axis on a horizontal plane. A second pair of arms having inner and outer ends are pivotally mounted on their inner ends to the arm support for pivotal movement about a horizontal axis in a vertical plane. A counterbalance spring is connected between the arm support and the second pair of arms and a lamp head is pivotally connected on the outer end of the second pair of arms for pivotal movement at least about a horizontal axis in a vertical plane.
Claims16
A mounting assembly for a lamp comprising a hollow elongated post having open ends and at least two internal channels adjacent each other in generally parallel relation, said at least two internal channels having open end portions and being adapted to receive mounting screws therein;
- a mounting block received in one end of said hollow elongated post and having first and second mounting sections, said first mounting section having a pair of throughbores formed therein for receiving mounting screws therethrough which are adapted to be received respectively in said at least two internal channels;
- said hollow elongated post having an open face adjacent said one end thereof and said second mounting section having a front face located in said open face of the hollow elongated post and a pivot boss formed thereon on said front face including a pivot opening formed therein for receiving a pivot mounting shaft of a lamp arm assembly.
A lamp assembly comprising a base, a lamp arm mounting adapter mounted on said base including a pivot boss formed thereon;
- a first pair of hollow support arms having inner and outer ends with said inner ends being pivotally mounted on the pivot boss of said mounting adapter for pivotal movement on a vertical axis and in a generally horizontal plane;
- an arm support pivotally mounted on the outer ends of said first pair of hollow support arms for pivotal movement on a vertical axis in a generally horizontal plane;
- a second pair of arms having inner and outer ends with the inner ends thereof pivotally mounted on said arm support for pivotal movement about a horizontal axis in a vertical plane;
- counter balance spring means connected between said arm support and said second pair of arms, and a lamp head pivotally connected to said outer ends of second pair of arms for pivotal movement at least about a horizontal axis in a vertical plane;
- said lamp head including a support neck pivotally connected to said outer ends of the second pair of arms and adapted to support a light bulb therein, a support ring rotatably mounted on said support neck on an axis which is located generally perpendicularly to an axis of pivotal connection of the support neck to the second pair of arms, a reflector mounted on said support ring, and a shade mounted on said support ring above said reflector.
A lamp assembly comprising a base, a lamp arm mounting adapter mounted on said base including a pivot boss formed thereon;
- a first pair of hollow support arms having inner and outer ends with said inner ends being pivotally mounted on the pivot boss of said mounting adapter for pivotal movement on a vertical axis and in a generally horizontal plane;
- an arm support pivotally mounted on the outer ends of said first pair of hollow support arms for pivotal movement on a vertical axis in a generally horizontal plane;
- and second pair of arms having inner and outer ends with the inner ends thereof pivotally mounted on said arm support for pivotal movement about a horizontal axis in a vertical plane;
- counter balance spring means connected between said arm support and said second pair of arms, and a lamp head having a support neck pivotally connected to said outer ends of second pair of arms for pivotal movement at least about a horizontal axis in a vertical plane;
- said first pair of hollow support arms and said second pair of arms being formed of electrically conducted materials and said arm support and support neck being formed of non-conductive materials.
