Abstract

A lamp frame assembly comprising a base having a sleeve for connecting a supporting frame through a coupling device, and a lamp holder connected to said supporting frame by a connecting frame assembly which is connected between said lamp holder and said supporting frame by two locking devices through which the angular position of the connecting frame assembly relative to the lamp holder and the supporting frame can be adjusted by a hand lever. By changing the sleeve on the base, the lamp frame assembly can be set up into a desk lamp or floor lamp. The base can be a wall fixture which incorporates the supporting frame, the connecting frame assembly and the lamp holder into a wall lamp.

Claims

1. A lamp frame assembly comprising:

a supporting frame having two opposite, eyes lugs at one end, and a plurality of hinge barrels aligned at an opposite end;

a connecting frame assembly having two opposite pairs of unitary screw rods respectively bent inwards at right angles at two opposite ends;

a lamp holder connected to said connecting frame at one end, said lamp holder having two stub tubes bilaterally extending outwards at one end and longitudinally aligned with each other, said two stub tubes each having a round hole for inserting either pair of the unitary screw rods of said connecting frame;

two locking devices for securing said lamp holder and said supporting frame to said connecting frame assembly at two opposite ends, each of which comprising a lock barrel set inside an insulator sleeve, said lock barrel having two rectangular holes at two opposite ends with two nuts set therein respectively for fastening either pair of the unitary screw rods of said connecting frame assembly;

a base comprising a body having a sleeve; and

a coupling device for connecting said supporting frame to the sleeve of said base, said coupling device comprising a movable member and a fixed member, said movable member having two opposite, eyed lugs at the top with two nuts respectively set therein for connecting to said hinge barrels by a screw rod, a vertical rod at the bottom inserted in a round hole on said fixed member and secured therein by a screw, and a cylindrical chamber around the vertical rod thereof for inserting said fixed member, said fixed member having a vertical rod at the bottom secured in the sleeve on said base by a lock screw.

2. The lamp frame assembly of claim 1, wherein said base comprises a body having an elongated sleeve vertically disposed at the center for connecting said coupling device permitting said lamp holder, said connecting frame assembly and said supporting frame to be incorporated thereto into a floor lamp, said body having an annular groove at the center defining therein a unitary stub screw rod for connecting said elongated sleeve through screw joint.

3. The lamp frame assembly of claim 1, wherein said base is a wall fixture for fastening said coupling device on a wall permitting said lamp holder, said connecting frame assembly and said supporting frame to be incorporated thereto into a wall lamp.
