Title:
INNERSPRING COILS AND INNERSPRINGS WITH NON-HELICAL SEGMENTS
Document Type and Number:
Japanese Patent JP2015051285
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that there is conventionally a substantial amount of wire material and structure on the bottom side of an innerspring which is excessive and not required for adequate or optimal performance of the single support surface.SOLUTION: Innerspring coils for innersprings for mattresses and other reflexive support structures, have generally helical coil bodies 72 and at least one non-helical segment or step 78 which extends between one or both of axial ends 74, 76 of the coil body and one or both of the coil ends. The step or steps are linear or nonlinear, and parallel to or angularly disposed with respect to a longitudinal axis of the coil body. When located proximate to the coil end 74, the step extends out of the plane in which the coil end lies. One or more steps may alternatively be formed intermediate to helical turns of the helical coil body.
