Title: Making curved glass fragment-type lamp shades - by soldering together double triangular shaped sections with blunt end forming polygon-shaped centre
Inventor: KNOP KARL-HEINZ
IPC: F21V1/20
Filed: 1992-06-11
Granted: 1993-11-04
Abstract: Prodn. of a curved body made out of glass fragments, esp. for producing glass lamp shades, consists of cutting out glass sections (1) using flat patterns having a symmetrical triangular shape (2) about a central axis (3). The corner having the acute angle (4) is cut perpendicular to the axis (3) to form a blunt end. An uneven number of sections is placed together so that the cut sides (5) form a polygon and the bevelled edges of the sections have a reducing distance (9) between themselves towards the centre (6). The sides of the sections are stuck together by a copper strip before the polygon edges are soldered together with copper wire.
