Abstract
Abstract A kit constituted by a set of modules which may be compactly packaged and shipped in flat form, and which may be readily assembled to create a table lamp having a box-like shade whose corners are supported on straight legs. The kit includes a set of four modules, each composed of a translucent panel, one edge of which is joined to a post whose length is greater than the length of the panel, the post having a longitudinal groove therein adapted to receive the free edge of the panel of an adjoining module whereby when assembled, the four modules define a box-like shade supported on corner posts. To complete the assembly, four legs are provided, each of which is adapted to slide over a post and to engage a longitudinal bead formed on the adjoining panel adjacent the free edge thereof, whereby each leg serves to lock the associated module post to the adjoining panel.

Claim 1
Independent Claim
193 words
A kit for producing a table lamp having an open-ended, boxlike shade supported at its corners on legs, said kit comprising: A. a set of four identical modules, each including a panel, one edge of which is joined to a post whose length is greater than that of the panel to define a flag-like structure, said post having a longitudinal groove therein substantially co-extensive with the edge of the panel and at right angles thereto, said groove accommodating the free edge of the panel of an adjoining module whereby the four modules may be interconnected to define said box-like shade, each panel having a longitudinal bead adjacent the free edge thereof, B. a set of four identical legs, each of which is telescopable on a respective one of said posts, each leg being provided with a flange adapted to engage the bead on the panel whose free edge is received in the groove on the associated post to thereby latch said free edge thereto, and C. a bracket to support a lamp socket within said box-like shade, said modules being formed from translucent plastic material and said panel being integral with said post.
Claim 2
Dependent Claim
