Abstract

Abstract A lamp shade structure is provided with a wire frame having a polystyrene wrap chemically welded thereon with an obverse surface comprising contact adhesive covered by discrete panels of peel-away protective paper. Corresponding discrete panels of decorative material, such as needlework decorated fabric, are substituted for the peel-away paper panels and the seams between adjacent panels masked by coterminously glued material strips such as grosgrain ribbon coated with clear drying adhesive. Top and bottom peripheral bands are folded over the end frames and form top and bottom borders on the obverse face of the decorated panels to hide the ends of the coterminous seam covering strips and provide a finished lamp structure.

Claim 3
Dependent Claim 22 words
The invention defined in claim 1, wherein said sheet of flexible base material is adhered on its interior surface to said struts.
Claim 4
Dependent Claim 22 words
The invention defined in claim 1, wherein said single lapped side seam is substantially coincident and coterminous with one of said struts.
Claim 5
Dependent Claim 39 words
The invention defined in claim 1, wherein said sheet of flexible base material is adhered on its interior surface to said struts; and wherein said single lapped side seam is substantially coincident and coterminous with one of said struts.
Claim 6
Dependent Claim 13 words
The invention defined in claim 1, wherein said flexible base material is polystyrene.
Claim 7
Dependent Claim 133 words
A blank for constructing decorated lamp shades comprising: a frame having a top peripheral band, a bottom peripheral band and vertically oriented strut members extending between said bands in a predetermined lamp shade configuration; a sheet of flexible base material wrapped coterminously about said frame and having a single lapped side seam therein; said base material having substantially is entire obverse face coated with a contact adhesive layer to provide a self-adhering side seam; said vertically oriented strut members defining a plurality of discrete obverse surface panels therebetween; a like plurality of conformally shaped discrete applied panels of peelable protective material adhered to said surface panels by said contact adhesive; said peelable panels being selectively removable to expose a discrete obverse panel of contact adhesive for receiving conformally shaped panels of decorative material.
Claim 8
Dependent Claim 133 words
A blank for constructing decorated lamp shades comprising: a frame having a top peripheral band, a bottom peripheral band and vertically oriented strut members extending between said bands in a predetermined lamp shade configuration; a sheet of flexible base material wrapped coterminously about said frame and having a single lapped side seam therein; said base material having substantially is entire obverse face coated with a contact adhesive layer to provide a self-adhering side seam; said vertically oriented strut members defining a plurality of discrete obverse surface panels therebetween; a like plurality of conformally shaped discrete applied panels of peelable protective material adhered to said surface panels by said contact adhesive; said peelable panels being selectively removable to expose a discrete obverse panel of contact adhesive for receiving conformally shaped panels of decorative material.
Claim 9
Dependent Claim 22 words
The invention defined in claim 6, wherein said sheet of flexible base material is adhered on its interior surface to said struts.
Claim 10
Dependent Claim 22 words
The invention defined in claim 6, wherein said single lapped side seam is substantially coincident and coterminous with one of said struts.
Claim 11
Dependent Claim 39 words

Claim 13
Independent Claim 281 words
The method of constructing a lamp shade from a plurality of discrete decorative surface panels overlying a sheet material substrate on a wire shade frame comprising: covering a wire lamp shade frame having a top and bottom band and connecting struts therebetween with a single sheet of flexible base material juxtaposed with said struts and coated on its obverse face with contact adhesive; overlapping said sheet on itself along one of said struts to form a self-adherent lapped side seam; applying adhesive means to the inner surface of said sheet coterminously with said struts to adhere said sheet thereto; trimming said sheet to conform to the top and bottom configurations of said frame; said obverse surface of said sheet being covered with a peelable protective layer in discrete removable sections; removing said peelable layer one discrete section at a time to selectively expose said contact adhesive; applying conformally shaped discrete sections of decorative material to said exposed contact adhesive section by section until the entire obverse surface has been covered thereby with seams extending between adjacent discrete sections; providing ribbon material the length of said seams; applying adhesive to said ribbon material; covering said seams by overlying said seams with said ribbon material and adhering said ribbon material to said adjacent decorative sections; providing strip material of sufficient length to peripherally border the top and bottom of said shade; applying adhesive to said strip material; and adhering said strip material to the top and bottom edges of the obverse surface of the shade and folding said strip material inward to cover said top and bottom bands to mask the latter and the exposed ends of any ribbon material adjacent said bands.
Claim 14
Independent Claim 281 words
The method of constructing a lamp shade from a plurality of discrete decorative surface panels overlying a sheet material substrate on a wire shade frame comprising: covering a wire lamp shade frame having a top and bottom band and connecting struts therebetween with a single sheet of flexible base material juxtaposed with said struts and coated on its obverse face with contact adhesive; overlapping said sheet on itself along one of said struts to form a self-adherent lapped side seam; applying adhesive means to the inner surface of said sheet coterminously with said struts to adhere said sheet thereto; trimming said sheet to conform to the top and bottom configurations of said frame; said obverse surface of said sheet being covered with a peelable protective layer in discrete removable sections; removing said peelable layer one discrete section at a time to selectively expose said contact adhesive; applying conformally shaped discrete sections of decorative material to said exposed contact adhesive section by section until the entire obverse surface has been covered thereby with seams extending between adjacent discrete sections; providing ribbon material the length of said seams; applying adhesive to said ribbon material; covering said seams by overlying said seams with said ribbon material and adhering said ribbon material to said adjacent decorative sections; providing strip material of sufficient length to peripherally border the top and bottom of said shade; applying adhesive to said strip material; and adhering said strip material to the top and bottom edges of the obverse surface of the shade and folding said strip material inward to cover said top and bottom bands to mask the latter and the exposed ends of any ribbon material adjacent said bands.
