Spring Containing (e.g., Coil Type) Patents (Class 5/655.7)
  • Patent number: 9392877
    Abstract: A mattress includes a spring extending between first and second points to provide a first spring rate in a first direction. A polymer fiber structure is provided between the first and second points and adjoins the spring. The polymer fiber structure includes fibers interlinked with one another to provide the second spring rate in the first direction. An example method of manufacturing a mattress is provided that includes arranging springs to provide a mattress innerspring. A polymer fiber structure is introduced in a first state to the innerspring to provide an assembly. The assembly is further processed and the polymer fiber structure is simultaneously altered from the first state to a second state.

  • Patent number: 8590079
    Abstract: The cushion according to the invention is made up of several layers of pneumatic elements (3) which each form a matrix (2). These pneumatic elements (3) each have a multiplicity of holes (5a) into which elastic spring elements, for example foam cylinders (1), are inserted. The pneumatic elements (3) are all substantially congruent, such that the holes (5a) of superposed pneumatic elements (3) are in each case located at the same places. An individual pneumatic element (3) is produced from two superposed sheets of an elastic plastic. The two sheets are welded sealingly to each other at the edges of the cushion and at the edges of the holes (5a). The holes (5a) are cut out after the welding. Each pneumatic element (3) has at least one connection for compressed gas. While supporting a patient, the pneumatic elements (3) are alternately supplied with compressed gas and then relaxed again.

    Abstract: Disclosed herein is a bedding or seating product (10) having a spring core (12) comprising coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one arcuate leg (76) longer than the other (78), the legs (76, 78) being joined by a connector (80) having an arcuate bump (81) therein. The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to be wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.

    Abstract: A method of making low density spring interior assemblies having rectangular arrays of spring positions, some of which are occupied by individual coil springs and some of which are empty, is provided. Preferably, the array is formed of rows of alternating springs and empty positions laced to similar rows offset from each other in a staggered arrangement so that spaces and springs alternate both transversely and longitudinally. Preferably the springs are unknotted. The assemblies are automatically formed on a system that includes at least one coil former, at least one conveyor, a transfer station or mechanism and a spring interior assembly machine. A coil former forms and loads springs individually onto a conveyor. The transfer station transfers rows of coils to the assembly machine, which laces rows of coils together in the array.
