Abstract

A lampshade structure is fabricated from a collapsible, semi-flexible sheet material onto which pre-fastened magnetic strips are attached. One or more collapsible spring steel strip hoop(s) is magnetically adhered to the magnetic strips to thereby create a semi-rigid tubular structure. As part of a kit in the collapsed configuration, each spring steel strip hoop is folded upon itself and the flexible sheet material with a pre-fastened magnetic strip is rolled into a small diameter. In the expanded configuration, the spring steel strip hoop(s) is unfolded and expanded, whereupon the sheet material with pre-fastened magnetic strip is wrapped around the circumference of the spring steel strip hoop(s) relying solely on magnetic attraction as a fastening system in creating a semi-rigid hollow structure. This resultant collapsed assembly is 1/9th the volume of the fully expanded structure, thereby saving considerable shipping costs, both in the labor required for packaging materials and actual transportation costs. Furthermore, insofar as the components of the lamps shade are pliable, the risk of deformation of the packaged lampshade is greatly diminished even if the container is damaged in the shipping process. As well a container 1/9 the volume of a full size container has proportionately greater strength and is less apt to suffer shipping damage.

Claims

1. A lampshade that comprises:

a support hoop; and

a lamp cover made of a flexible material that forms a continuous, open-ended configuration having an edge that is secured to the support hoop by magnetic means.

2. The lampshade of claim 1 wherein the lamp cover is made of a single sheet of relatively rigid material having two longitudinally-extending sides that are secured to each other and the lamp cover is self-supporting when its upper edge which defines a periphery that is secured to the support hoop.

3. The lampshade of claim 1 wherein the lamp cover has a substantially continuous circular shaped cross section.

4. The lampshade of claim 1 wherein the edge of the lamp cover has a strip of magnetic material attached thereto.

5. A lampshade of claim 1 comprising:

an upper support hoop; and

a lower support hoop, wherein the lamp cover has upper and lower edges, wherein the upper edge is secured to the upper support hoop by magnetic means and the lower edge is secured to the lower support hoop by magnetic means.

6. The lampshade of claim 5 wherein the lamp cover is made of a single sheet of relatively rigid material having two longitudinally-extending sides that are secured to each other and the lamp cover is self-supporting when its upper edge which defines an upper periphery is secured to the upper support hoop and its lower edge which defines a lower periphery is secured to the lower support hoop.

7. The lampshade of claim 5 further comprising a mounting hub that is connected to the upper support hoop by a series of spokes in radiating fashion.

8. The lampshade of claim 5 further comprising a diffuser that is secured to the lower support hoop.

9. The lampshade of claim 8 wherein the diffuser has an annular contour outer perimeter and has an aperture that defines an inner perimeter, wherein the outer perimeter is secured to the lower support hoop.

10. The lampshade of claim 5 wherein the upper and lower edges of the lamp cover each has a strip of magnetic material attached thereto.

11. The lampshade of claim 5 wherein no longitudinally extending support member connecting the upper and lower support hoops is required to maintain the lamp covers as self-supporting.

12. A lampshade that comprises:

an upper support hoop;

a lower support hoop;

a lamp cover formed of flexible material and having a tubular-shaped structure with upper and lower perimeters, wherein the upper perimeter is secured to the upper support hoop by first magnetic means and the lower perimeter is secured to the lower support hoop by second magnetic means, wherein the lamp cover is self-supporting; and

a mounting hub connected to the upper support hoop by a plurality of support members.

13. The lampshade of claim 12 further comprising a diffuser that is secured to the lower support hoop.

14. The lampshade of claim 12 wherein the diffuser has an annular contour outer perimeter and has an aperture that defines an inner perimeter, wherein the outer perimeter is secured to lower support hoop.

15. A kit for forming a collapsible lampshade that comprises:

a lamp cover formed of a sufficiently rigid material that is stable on a longitudinal axis and has an expanded configuration in the form of a continuous, open-ended structure having an edge; and

a support hoop that is formed of a collapsible metal strip wherein the support hoop is dimensioned to be secured to the edge of the lamp cover by magnetic means.

16. The kit of claim 15 wherein the collapsible metal strip that forms the support loop has a collapsed configuration wherein the metal strip is folded upon itself with a diameter that is approximately half that of the metal strip in its expanded configuration.

17. The kit of claim 15 wherein the lamp covers is made from plastic or paper.

18. The kit of claim 15 wherein the edge of the lamp cover has a strip of magnetic material attached thereto.

19. The kit of claim 15 wherein the lamp cover define upper and lower edges and the kit comprises:

an upper support hoop that is formed of a collapsible metal strip wherein the upper support hoop is dimensioned to be secured to the upper edge of the lamp cover by first magnetic means;

a lower support that is formed of a metal strip wherein the lower support hoop is dimensioned to be secured to the lower edge of the lamp cover by second magnetic means; and

a mounting hub that is configured to be connected to the upper support hoop by a series of spokes

20. The kit of claim 19 further comprising a diffuser that is secured to the lower support hoop.

21. The kit of claim 20 wherein the diffuser has an annular contour outer perimeter and has an aperture that defines an inner perimeter, wherein the outer perimeter is secured to lower support hoop.

22. The kit of claim 19 wherein the upper and lower edges of the lamp cover each has a strip of magnetic material attached thereto.
