Problems solved by technology

This problem is exacerbated by coils having a centrally tapered helical pattern, where the central region of the coil body has a small diameter that tapers relative to the ends of the coil, making the coil axially unstable under full compression for packaging processing , causing the coil to rotate or shift under the pressure of the package out of axial alignment

Embodiment Construction

[0014] Referring to the drawings, there is shown a tall profile innerspring coil generally indicated at 10 having an overall ultimate end-to-end length or height dimension generally in the range of six and three-quarters to seven and one-half inches (or approximately 170 -190mm range). The coil 10 is formed from helical form wire (eg, 12-16 gauge) as a helix 13 with adjacent end helices 16 at opposite ends of the coil body. In this particular embodiment, there are three helices or turns forming the coil body, including intermediate helices 14 a and 14 b , and central helix 12 . Another embodiment of the coil of the present invention may be constructed in a different configuration, eg a different number of helices or turns, and a different shape of the coil ends, as described further below. In the particular embodiment of a five-turn helical coil, the central helix 12 has the smallest diameter, and the diameters of adjacent intermediate helices 14a and 14b become larger by a d...

Abstract

A high profile coil having an overall height in the range of six and three quarters to seven and one half inches retains axial alignment under compression. High-profile innersprings constructed from these high-profile coils can be packaged with other high-profile innersprings in packaging machines without slipping or sideways deflection. Axial compression of the coils avoids contact of adjacent coils in the innerspring under various loads.

Description

technical field [0001] The present invention relates generally to coil, spring and innerspring assemblies for reflexive support such as seat cushions and mattresses, and more particularly to coil and innerspring patterns that can be compressed during packaging for shipping and handling . Background technique [0002] Innerspring assemblies used as kickbacks and support cores to support devices such as seat cushions and mattresses are typically made from multiple coils, or springs, connected in various arrangements. In wire innersprings, the coils are usually helical, and the ends are usually stamped and formed to provide a foot or support surface for interfacing with covering padding and trim. The innerspring coils are typically connected together in a matrix or array by braiding adjacent turns with cross-helical wires that extend the width or length of the innerspring. The height (also referred to as "length") of the coils, measured end-to-end, represents the height of th...
