Abstract

A lamp shade which can be collapsed to reduce its size for shipping, display and storage, having an upper ring, a lower rings, and a cover. The cover of the lampshade is relatively stiff, particularly when formed into a taught cone or cylinder. It is self supporting when assembled, but the cover may still be collapsed when disassembled for shipment or storage. In one embodiment, the rings are placed into corresponding upper and lower edges of the cover and held in place by press-fitting a plurality of fitting nubs protruding from the perimeter of the rings into sockets attached along the insides of the edges. In another embodiment, the rings are held in place by press-fitting the band of the rings between jaws of a plurality of clips placed around the edges. In a third embodiment, the rings are held in place by a combination of the above two methods.

Claims

1. A collapsible lampshade, comprising:

an upper ring;

a lower ring;

each of said upper and lower rings comprising a circular band, deformed with planar indentations at a plurality of locations and fixing nubs permanently attached to said rings within said indentations;

a cover having an upper and a lower edge wherein;

said edges have respective inside surfaces;

wherein said cover has an interior area between said upper and lower inside surfaces; and

wherein said cover has at least one longitudinal seam between said edges engaging two ends of at least one cover section;

a plurality of ring holders associated with said respective inside surfaces, creating respective upper and lower ring holders, and including sockets having socket holes oriented toward said interior area of said cover; and

a mounting spider having a mounting hub and a plurality of legs permanently attachable to one of said upper and lower rings;

wherein, to assemble said collapsible lampshade said upper and lower rings are placed along said inside surfaces of said respective upper and lower edges and are fixed thereto by engaging said respective upper and lower ring holders with said upper and lower rings, wherein;

said engaging said respective upper and lower ring holders with said upper and lower rings comprises placing said fixing nubs into said respective socket holes when said upper and lower rings are placed against said respective upper and lower edges.

2. The collapsible lampshade of claim 1, wherein:

said upper and lower edges are of a diametric size, relative to said corresponding upper and lower rings, so as to create tension within said edges when said rings are placed along said inside surfaces, and wherein said tension holds said upper and lower rings in position within said corresponding upper and lower ring holders.

3. The collapsible lampshade of claim 1, wherein said collapsible lampshade forms its intended shape when said rings are placed along said inside surfaces.

4. The collapsible lampshade of claim 1, wherein said collapsible lampshade collapses when said upper and lower rings are removed from along said inside surfaces of said upper and lower edges of said cover.

5. The collapsible lampshade of claim 1, wherein said cover is made of relatively stiff material and that said lampshade is self-supporting when said upper and lower rings are placed along said inside surfaces of said upper and lower edges with said upper and lower rings engaged with said corresponding upper and lower ring holders.

6. The collapsible lampshade of claim 1 wherein:

said legs of said mounting spider may project away from said mounting hub in one of an upward or downward conical arrangement with said mounting hub defining a vertex of said arrangement; and

said mounting hub is located within said interior area of said cover with said spider permanently affixed to either one of said upper or lower rings and said lampshade is assembled.

7. The collapsible lampshade of claim 1 wherein:

said upper and lower rings comprise circular bands having a diameter;

said ring holders comprise clips having upper and lower jaws spaced apart at a distance of said diameter and oriented toward said interior area of said cover; and

said engaging said respective upper and lower ring holders with said upper and lower rings comprises placing said bands in between said respective jaws when said upper and lower rings are placed against said respective upper and lower edges.

8. The collapsible lampshade of claim 1 wherein said engaging two ends of at least one cover section of a longitudinal seam comprises an overlap of said two ends with said overlap being permanently engaged by gluing.

9. The collapsible lampshade of claim 1 wherein said engaging two ends of at least one cover section of a longitudinal seam comprises interweaving two sides of an alternating, opposing-flap interlocking system.

10. The collapsible lampshade of claim 1 wherein said lower ring comprises at least two radially curved sections with mating ends held together by a connection device.

11. The collapsible lampshade of claim 10 wherein said connection device comprises a connection tube having an inner diameter which, when placed over said mating ends, securely surrounds said ends, holding said ends together.

12. A collapsible lampshade, comprising:

an upper ring;

a lower ring;

a cover having an upper and a lower edge wherein;

said edges have respective inside surfaces;

wherein said cover has an interior area between said upper and lower inside surfaces; and

wherein said cover has at least one longitudinal seam between said edges engaging two ends of at least one cover section;

a plurality of ring holders associated with said respective inside surfaces, creating respective upper and lower ring holders, and

a mounting spider having a mounting hub and a plurality of legs permanently attachable to one of said upper and lower rings;

wherein, to assemble said collapsible lampshade said upper and lower rings are placed along said inside surfaces of said respective upper and lower edges and are fixed thereto by engaging said respective upper and lower ring holders with said upper and lower rings, wherein;

each of said upper and lower rings comprise a circular band, deformed with planar indentations at a plurality of locations and having a diameter;

fixing nubs are permanently attached to said rings within said indentations;

said ring holders comprise sockets having socket holes oriented toward said interior area of said cover and clips having upper and lower jaws spaced apart at a distance of said diameter and oriented toward said interior area of said cover; and
