Abstract

An adjustable lamp shade includes at least one (1) section that has an array of horizontal louvers located on a side thereof. Each respective array of louvers is controlled by an actuating mechanism.

Claims (44)

1. A lamp with an adjustable lamp shade comprising:

a shade assembly, comprising:

at least one louver assembly, each located on an individual side of said shade assembly and each comprising:

a frame;

a plurality of slats, each horizontally attached between opposing sides of said frame; and

an actuating mechanism in rotatable communication with said plurality of slats; and

at least one shade panel, each located on remaining sides of said shade assembly;

a base;

a harp, attached to an upper part of said base, said harp supporting said shade assembly thereon; and

an illuminating device, attached to said base and capable of being in electrical communication with a power source;

wherein said plurality of slats are capable of freely rotating respective to said frame;

wherein rotation of said actuating mechanism in a first direction opens said plurality of slats; and

wherein rotation of said actuating mechanism in a second direction closes said plurality of slats slats

wherein said actuating mechanism further comprises an upper shaft located at an upper end of said frame, capable of freely rotating relative to said frame; a drive axle located at a bottom end of said frame, disposed parallel with said upper shaft, and having a first end capable of rotating freely within said frame; at least one coupling element attached to each of said plurality of slats, each coupling element having a first distal end attached to said upper shaft and a second distal end attached to and in mechanical communication with said drive axle; and an adjustment knob located adjacent a bottom of said frame and in mechanical communication with a second end of said drive axle; and

wherein said plurality of slats are disposed between said upper shaft and said drive axle.

2. The lamp of claim 1 , further comprising idler pulleys attaching said first distal end of each said coupling element to said upper shaft and said second distal end of each coupling element to said drive axle.

3. The lamp of claim 2 , further comprising a ninety degree bevel gear assembly, having a first end in mechanical communication with said adjustment knob and a second end in mechanical communication with said drive axle.

4. The lamp of claim 2 , wherein each coupling element is a braided ladder cord.

5. The lamp of claim 2 , wherein distal ends of each of said plurality of slats are held within said frame.

6. The lamp of claim 2 , wherein said frame is generally pyramidal in shape.

7. The lamp of claim 6 , further comprising two louver assemblies located directly opposite each other.

8. The lamp of claim 2 , wherein said frame is generally cuboid in shape.

9. The lamp of claim 8 , further comprising two louver assemblies located directly opposite each other.

10. An adjustable lamp shade, comprising:

a shade assembly, comprising:

at least one louver assembly, each located on an individual side of said shade assembly and each comprising:

a frame;

a plurality of slats, each horizontally attached between opposing sides of said frame; and

an actuating mechanism in rotatable communication with said plurality of slats; and

at least one shade panel, each located on remaining sides of said shade assembly;

wherein said lamp shade is configured to be installed on a lamp having a base and an illuminating device capable of being in electrical communication with a power source;

wherein said plurality of slats are capable of freely rotating respective to said frame;

wherein rotation of said actuating mechanism in a first direction opens said plurality of slats; and,

wherein rotation of said actuating mechanism in a second direction closes said plurality of slats

wherein said actuating mechanism further comprises an upper shaft located at an upper end of said frame, capable of freely rotating relative to said frame; a drive axle located at a bottom end of said frame, disposed parallel with said upper shaft, and having a first end capable of rotating freely within said frame; at least one coupling element attached to each of said plurality of slats, each coupling element having a first distal end attached to said upper shaft and a second distal end attached to and in mechanical communication with said drive axle; and an adjustment knob located adjacent a bottom of said frame and in mechanical communication with a second end of said drive axle; and,

wherein said plurality of slats are disposed between said upper shaft and said drive axle.

11. The lamp shade of claim 10 , further comprising idler pulleys attaching said first distal end of each said coupling element to said upper shaft and said second distal end of each coupling element to said drive axle.

12. The lamp shade of claim 11 , further comprising a ninety degree bevel gear assembly, having a first end in mechanical communication with said adjustment knob and a second end in mechanical communication with said drive axle.

13. The lamp shade of claim 11 , wherein each coupling element is a braided ladder cord.

14. The lamp shade of claim 11 , wherein distal ends of each of said plurality of slats are held within said frame.

15. The lamp shade of claim 11 , wherein said frame is generally pyramidal in shape.

16. The lamp shade of claim 15 , further comprising two louver assemblies located directly opposite each other.

17. The lamp shade of claim 11 , wherein said frame is generally cuboid in shape.

18. The lamp shade of claim 17 , further comprising two louver assemblies located directly opposite each other.
