Abstract

1394575 Spring upholstery CROSBY SPRING INTERIORS Ltd 4 April 1973 [5 April 1972] 15769/72 Heading A4M A spring unit is formed from a single, elongate, serpentine spring 10, 12 by deforming the spring and constraining it to define an overall shape in the form of a substantially rectangular prism having upper and lower, spaced planar portions linked together by resilient cross members. The spring may be deformed to define a succession of triangular sections by connecting alternate straight portions 10 of the spring to the sixth next portion 10 by means of a helical wire 14. Several spring units may be secured together to and within a frame.
