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.
Claims13
An open coil spring assembly, comprising:
- a plurality of rows of open coil springs arranged to form a matrix of the open coil springs, 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 upper end convolution having a first flattened portion adjacent to the plurality of helical convolutions and located on a first side of the open coil spring, a second flattened portion adjacent to a terminal end of the open coil spring and located on a second side of the open coil spring opposite the first side, and a third flattened portion positioned between the first flattened portion and the second flattened portion and located on a third side of the open coil spring different from the first side and the second side;
- and
- a plurality of clips each connecting one or more of said open coil springs, each of said clips having a hollow area to receive one or more of the three flattened portions of said adjacent open coil springs and each of said clips attached to one or more of the three flattened portions of said upper end convolutions of said open coil springs;
- wherein for each of said plurality of rows of open coil springs, each open coil spring is connected to a first adjacent open coil spring with one of said plurality of clips attaching said first flattened portion of said open coil spring to said first flattened portion of said first adjacent open coil spring, and each open coil spring is connected to a second adjacent open coil spring with another one of said plurality of clips attaching said second flattened portion of said open coil spring to said second flattened portion of said second adjacent open coil spring;
- and
- wherein for each of said plurality of rows of open coil springs, each open coil spring of said row is connected to a third adjacent open coil spring in an adjacent row of open coil springs with another one of the plurality of clips attaching said third flattened portion of said open coil spring to said third flattened portion of the third adjacent open coil spring, such that said row of open coil springs is alternatingly connected to adjacent rows on either side of said row.
