Abstract
Abstract A knock-down kit for forming a lamp shade, a waste-basket and other similar types of articles. The knock-down kit includes as its principal elements a side wall member and a pair of hoop members which are formed with a U-shaped channel for receiving therein the upper and lower edges, respectively, of the side wall member. The hoop members include locking means within the Ushaped channel which, when the upper and lower edges of the side wall member are inserted within the U-shaped channel, lockingly affix the hoop members to the side wall member. In the case of a lamp shade, the kit further includes a spider member having spider arms, the ends of which are secured to the hoop member affixed to the upper edge of the side wall member, to complete the construction of the lamp shade. In the case of a wastebasket or the like, one of the hoop members is provided with a center wall which, when the hoop member is affixed to the lower edge of the side wall member, provides a closed bottom on the side wall member, hence forming a wastebasket.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
A knock-down kit for forming a lamp shade comprising, in combination: a tubular shade member having upper and lower edges; and a pair of substantially rigid hoop members having at least an outer wall, a concentric inner wall and a top section interconnecting them to form a generally U-shaped channel for receiving therein respective ones of the upper and lower edges of said shade member, and a plurality of spaced-apart barb-like locking means provided on at least one of said outer and inner walls and extending into said channel; said hoop members being affixable to said shade member by inserting the upper and lower edges thereof into the U-shaped channel of the respective ones of said hoop members, said U-shaped channel and said barb-like locking means being proportioned such that said barb-like locking means automatically lockingly engage with said shade member to secure said hoop member to said shade member.
Claim 2
Dependent Claim
150 words
A knock-down kit for forming a lamp shade comprising, in combination: a tubular shade member having upper and lower edges; and a pair of substantially rigid hoop members having at least an outer wall, a concentric inner wall and a top section interconnecting them to form a generally U-shaped channel for receiving therein respective ones of the upper and lower edges of said shade member, and a plurality of spaced-apart barb-like locking means provided on at least one of said outer and inner walls and extending into said channel; said hoop members being affixable to said shade member by inserting the upper and lower edges thereof into the U-shaped channel of the respective ones of said hoop members, said U-shaped channel and said barb-like locking means being proportioned such that said barb-like locking means automatically lockingly engage with said shade member to secure said hoop member to said shade member.
Claim 3
Dependent Claim
46 words
The knock-down kit of claim 1, wherein said shade member has a plurality of spaced-apart openings about its periphery adjacent the upper and lower edges thereof, said locking means being formed to lockingly engage within said openings to secure said hoop members to said shade member.
Claim 4
Dependent Claim
47 words
