The upper strip may have any of several forms and may include two channels, one for the hoop and one for a shadesupporting cross piece.

Claims

1. A kit for forming a lampshade comprising a hoop, a piece of flexible covering material, a resilient preformed flexible strip which is substantially as long as the circumference of said hoop, said strip having a constant cross section, a first portion of said strip being attached to one edge of said material and a second portion of said strip being shaped to provide a channel having a mouth of lesser width than the thickness of said hoop whereby said hoop may be sprung into said channel so that said strip and said covering material may be attached resiliently to said hoop to form a lampshade.

2. A kit as claimed in claim 1 wherein a second hoop and a second resilient preformed flexible strip is provided attached to said material, said second strip being substantially as long as said second hoop and having a portion shaped to provide a second channel having a mouth of lesser width than the thickness of said second hoop into which second channel said second hoop may be sprung.

3. A kit as claimed in claim 1 in which there is a crossmember for attachment of the shade to a light fitting and engagement means for attaching said crossmember to said strip.

4. A lampshade comprising a hoop, a resilient preformed flexible strip having a constant cross section, a first portion and a second portion of said strip, a frustoconical lampshade cover attached to said strip, said first portion of said strip being attached to one edge of said frustoconical cover, and said second portion forming a channel having a mouth of lesser width than the thickness of said hoop into which said hoop is sprung.

5. A lampshade as claimed in claim 4 having a second hoop, a second strip of resilient preformed flexible material having a first portion and a second portion, said first portion of said second strip being attached to the other edge of said frustoconical cover, and said second portion of said second strip forming a channel having a mouth of lesser width than the thickness of said second hoop, into which said second hoop is sprung.

6. A lampshade as claimed in claim 4 comprising a crossmember having means for attachment to a light fitting, said first strip having a cross section having a third portion shaped to receive the ends of said crossmember, said crossmember extending across said first hoop and having its ends engaged with said third portion.
