ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to lamps and more specifically to an adjustable lamp which has a light bulb that may be moved to different heights and to different orientations without the need for tools or the untightening of a fastener.
2. Discussion of the Prior Art
There are numerous prior art lamps which allow the light bulb to be raised and lowered and rotated about a stationary post. However, these prior art lamps require the use of a tool or the unscrewing of a fastener to allow the light bulb to be moved.
Accordingly, there is a clearly felt need in the art for an adjustable lamp with a light bulb that may be adjusted for height and orientated without the need for tools or the untightening of a fastener.
SUMMARY OF THE INVENTION
The present invention provides a lamp which has a light bulb that may be adjusted to different heights and orientations without the use of tools or the unthreading of a fastener. According to the present invention, an adjustable lamp includes a base, a pole, a cantilever member, a light bulb assembly, and a lamp shade. The pole is attached to the base. A pole opening is formed through substantially a first end of the cantilever member which is sized to slidably receive the pole. An assembly opening is preferably formed at a second end of the cantilever member for attachment of the light bulb assembly to the cantilever member. The light bulb assembly preferably includes a light bulb socket, a light bulb, a spacer, and an electrical cord. The bottom of the light bulb socket is inserted through the spacer. A bottom of the light bulb socket is inserted through the assembly opening and fastened to the cantilever member. The light bulb is screwed into the light bulb socket. A lamp shade is attached to the light bulb or lamp socket, or adjustable lamp. The position of the light bulb is adjusted by lifting up the cantilever member, sliding the cantilever member to a desired position, and finally lowering thereof.
Accordingly, it is an object of the present invention to provide an adjustable lamp which has a light bulb that may be positioned at different heights or orientations without using tools or the untightening of a fastener.
These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.
