Abstract
Abstract An improved lamp shade having a plurality of glass panels each having a plurality of side edges which are angularly inclined to one another to form corners therebetween, including a panel support structure consisting of a corner collar extending about the corners of each panel and connector means for interconnecting the collars to secure panels with respect to one another. The connector means consists of an elongated body disposed within a narrow passage between adjacent panels. The connector means has hook-shaped portions at either end thereof connected to adjacent corner collars of adjacent panels to connect the panels together. The elongated body of the connector means has abutting surfaces disposed at opposite sides thereof extending longitudinally thereof in a face-to-face abutting relationship with each of the adjacent side edges of the glass panels to maintain the side edges of the panels in a spaced parallel relationship. The abutting surfaces of the elongated body having a sufficient longitudinal extent to distribute loads applied thereto along a substantial length of the side edges of the glass panels thereby to prevent damage to the panels during shipping and handling.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
197 words
In a lamp shade which includes a plurality of glass panels, each having a plurality of side edges which are angularly inclined to one another to form corners therebetween, the side edges of at least two of said panels being juxtaposed and forming a narrow passage therebetween, and a panel support structure which includes a corner collar extending about each corner at each of said adjacent sides, the improvement of connector means for interconnecting said collars to secure said panels with respect to one another comprising, an elongated body disposed within said narrow passage and having means at either end thereof connected to adjacent corner collars of adjacent panels to connect said panels together, said elongated body having abutting surfaces disposed at opposite sides thereof and extending longitudinally thereof in a face-to-face abutting relationship with each of said adjacent edges of said glass panels to maintain said side edges of said panels in a spaced parallel relationship, said abutting surfaces of said elongated body having a sufficient longitudinal extent to distribute loads applied thereto along a substantial length of said side edges of said glass panels thereby to prevent damage to the panels during shipping and handling.
Claim 2
Dependent Claim
197 words
In a lamp shade which includes a plurality of glass panels, each having a plurality of side edges which are angularly inclined to one another to form corners therebetween, the side edges of at least two of said panels being juxtaposed and forming a narrow passage therebetween, and a panel support structure which includes a corner collar extending about each corner at each of said adjacent sides, the improvement of connector means for interconnecting said collars to secure said panels with respect to one another comprising, an elongated body disposed within said narrow passage and having means at either end thereof connected to adjacent corner collars of adjacent panels to connect said panels together, said elongated body having abutting surfaces disposed at opposite sides thereof and extending longitudinally thereof in a face-to-face abutting relationship with each of said adjacent edges of said glass panels to maintain said side edges of said panels in a spaced parallel relationship, said abutting surfaces of said elongated body having a sufficient longitudinal extent to distribute loads applied thereto along a substantial length of said side edges of said glass panels thereby to prevent damage to the panels during shipping and handling.
Claim 3
Dependent Claim
25 words
A lamp shade as claimed in claim 1 wherein said connector means consists of a wire member folded upon itself to form said abutting surfaces.
Claim 4
Dependent Claim
69 words
A lamp shade as claimed in claim 1 wherein said connector means consists of a wire member folded upon itself at either end thereof to form hook-shaped end portions for connecting the corner collars as aforesaid, each of said hook-shaped portions having an arm thereof extending longitudinally thereof to form said abutting surfaces whereby said panels are held in a spaced relationship at opposite ends of said connector means.
Claim 5
Dependent Claim
108 words
A lamp consisting of a lamp shade as claimed in claim 1 wherein one of said panels is a centrally located horizontally extending flat panel having an upper surface and a lower surface, a passage opening through said centrally located panel, and substantially rigid upper and lower flat annular reinforcing rings bonded in a face-to-face relationship with respect to the upper and lower surfaces of said central panel respectively and arranged to extend radially outwardly from said central passage to a diameter which is at least twice the diameter of the central passage, and lamp fixture means mounted in said central passage and supported by said reinforcing rings.
Claim 6
Dependent Claim
63 words
A lamp shade as claimed in claim 1 wherein at least the juxtaposed side edges of said glass panels are chamferred to avoid presentation of a sharp edge to the abutting surfaces of said elongated body and to diffuse light passing therethrough whereby in use the panel gives the impression of being made from thinner glass than it is in fact made from.
Claim 7
Dependent Claim
18 words
A lamp shade as claimed in claim 1 wherein said juxtaposed panels are made from transparent plate glass.
Claim 8
Dependent Claim
18 words
A lamp shade as claimed in claim 1 wherein said juxtaposed panels are made from smoked plate glass.
