Abstract
Abstract The lamp shade comprises a cover fabricated from a generally rectangular sheet of flexible material to which composite tape units are attached adjacent the upper and lower edges thereof. Each tape unit includes a first pile-type fastener tape having its back side secured to the sheet adjacent the top edge thereof, a fabric tape attached to the first pile-type fastener tape and a second pile-type fastener tape attached to the fabric tape along the edge thereof opposite the edge to which the first pile-type fastener tape is attached so that the fabric tape can be looped or folded about a conventional lamp shade ring and the second pile-tape fastener tape then releasably engaged with the first pile-type fastener tape to maintain the sheet of flexible material in a generally cylindrical configuration. Adjacent the end edges of the sheet are additional Velcro tapes which are releasably engageable in order to retain the end edges in an overlapped relationship, thereby further assisting in maintaining the generally cylindrical configuration of the lamp shade.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
98 words
An assemblable and disassemblable lamp shade comprising a sheet of flexible material having at least one edge, a first pile-type fastener tape having its back side secured to one side of said sheet adjacent said one edge thereof, a second pile-type fastener tape releasably engageable with said first pile-type fastener tape, and foldable means connected to and extending between adjacent edges of said pile-type fastener tapes, whereby said foldable means can be looped inwardly about a conventional lamp shade ring and said second pile-type fastener tape releasably engaged at said one side with said first pile-type fastener tape.
Claim 2
Dependent Claim
98 words
An assemblable and disassemblable lamp shade comprising a sheet of flexible material having at least one edge, a first pile-type fastener tape having its back side secured to one side of said sheet adjacent said one edge thereof, a second pile-type fastener tape releasably engageable with said first pile-type fastener tape, and foldable means connected to and extending between adjacent edges of said pile-type fastener tapes, whereby said foldable means can be looped inwardly about a conventional lamp shade ring and said second pile-type fastener tape releasably engaged at said one side with said first pile-type fastener tape.
Claim 3
Dependent Claim
17 words
The lamp shade of claim 1 in which said foldable means includes a strip of fabric tape.
Claim 4
Dependent Claim
22 words
The lamp shade of claim 2 in which said pile-type fastener tapes are stitched to opposite marginal portions of said fabric tape.
Claim 5
Dependent Claim
40 words
The lamp shade of claim 3 in which the back side of said first pile-type fastener tape is adhesively secured to said one side of said sheet which one side is to constitute the inner surface of said lamp shade.
Claim 6
Dependent Claim
69 words
The lamp shade of claim 4 in which said sheet has second and third edges extending generally perpendicularly to said one edge, a third pile-type fastener tape having its back side adhesively secured to said inner surface of said sheet adjacent said second edge and a fourth pile-type fastener tape having its back side adhesively secured to the outer or other surface of said sheet adjacent said third edge.
Claim 7
Dependent Claim
149 words
An assemblable and disassemblable lamp shade comprising a generally rectangular panel of flexible material having generally parallel upper and lower edges and generally parallel opposite end edges, a first pile-type fastener tape having its reverse side thereof secured to one side of said panel adjacent its said upper edge, a fabric tape secured along the edge of said pile-type fastener tape adjacent the edge thereof nearer the upper edge of said panel, and a second pile-type fastener tape secured along the edge of said fabric tape remote from the edge thereof that is secured to said first pile-type fastener tape, whereby said fabric tape can be looped about a circular lamp shade ring and said second pile-type fastener tape releasably engaged at said one side with said first pile-type fastener tape to maintain said rectangular panel in a generally cylindrical configuration corresponding to the circular shape of said ring.
Claim 8
Dependent Claim
149 words
An assemblable and disassemblable lamp shade comprising a generally rectangular panel of flexible material having generally parallel upper and lower edges and generally parallel opposite end edges, a first pile-type fastener tape having its reverse side thereof secured to one side of said panel adjacent its said upper edge, a fabric tape secured along the edge of said pile-type fastener tape adjacent the edge thereof nearer the upper edge of said panel, and a second pile-type fastener tape secured along the edge of said fabric tape remote from the edge thereof that is secured to said first pile-type fastener tape, whereby said fabric tape can be looped about a circular lamp shade ring and said second pile-type fastener tape releasably engaged at said one side with said first pile-type fastener tape to maintain said rectangular panel in a generally cylindrical configuration corresponding to the circular shape of said ring.
Claim 9
Dependent Claim
