Abstract
Present embodiments provide various open coil spring assemblies which perform like an encased spring assembly. The embodiments have elastic lacings or connections which connect springs to springs or springs to lacings. Various spring embodiments are provided as well as various arrangements for the elastic lacings. All of these features improve compliance and stability while reducing motion transfer.
Claims11
An open coil spring assembly, comprising:
- a plurality open coil springs including an upper end convolution, a lower end convolution, and a plurality of helical convolutions that extend between the upper end convolution and the lower end convolution, each of the open coil springs including (a) an upper spring portion that includes the upper end convolution and that is conical and (b) a lower spring portion that is cylindrical;
- and
- upper lacings extending between the plurality of rows,
- wherein the plurality of open coil springs are arranged in a matrix with a plurality of rows of open coils springs such that for each of the open coil springs, the upper end convolution of the open coil spring and the upper end convolution of an adjacent open coil spring are spaced apart, and
- wherein for each of the open coil springs, at least one upper lacing connects the upper end convolution of the open coil spring to the upper end convolution of an open coil spring of an adjacent row.
