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.
Claims8
An open coil spring assembly, comprising:
- a plurality of rows of open coil springs arranged in a matrix, each of the 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;
- a first set of upper lacings extending between the plurality of rows, each of the upper lacings in the first set extending in a first direction;
- and
- a second set of upper lacings extending between the plurality of rows, each of the upper lacings in the second set extending in a second direction different than the first direction;
- wherein for each of the open coil springs, at least one of the first set of upper lacings connects the open coil spring to an open coil spring of an adjacent row, and at least one of the second set of upper lacings connects the open coil spring to an open coil spring of an adjacent row.

An open coil spring assembly, comprising:
- a plurality of open coil springs arranged in a plurality of rows and a plurality of columns perpendicular to the rows, each of the 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, the plurality of open coil springs;
- a first set of upper lacings extending between the plurality of rows and the plurality of columns, each of the upper lacings in the first set extending in a first direction;
- and
- a second set of upper lacings extending between the plurality of rows and the plurality of columns, each of the upper lacings in the second set extending in a second direction different than the first direction;
- wherein the first set of upper lacings and the second set of upper lacings are connected to form a net;
- and
- wherein for each of the open coil springs, at least one of the first set of upper lacings connects the open coil spring to an open coil spring of an adjacent row and an adjacent column, and at least one of the second set of upper lacings connects the open coil spring to an open coil spring of an adjacent row and an adjacent column.
