Wire grid and wire spring module for use with a furniture spring assembly

A furniture spring assembly including:

• a bottom frame;
• a wire grid disposed above said bottom frame and comprising a plurality of elongate, generally coplanar straight tension wires arranged in generally perpendicular crossing relation to one another, said tension wires comprising a first sub-plurality of spring placement wires extending in generally spaced parallel relation to one another and a second sub-plurality of spring seating wires extending in generally parallel relation to one another and in generally perpendicular relation to said spring placement wires;
• and
• a plurality of wire spring modules extending between and connecting said wire grid and said bottom frame, at least one of said wire spring modules comprising,
• (i) a top for connecting said wire spring module to said wire grid, said top including a first end segment extending generally parallel to and in abutment with one of said spring placement wires, a second end segment generally coplanar with said first end segment and extending generally parallel to and in abutment with another one of said spring placement wires, and a connecting segment generally coplanar with and extending between said first and said second end segments, and
• (ii) a pair of legs each formed in a resilient spring configuration, each said leg extending from an end of a respective said end segment to said bottom frame.

A furniture spring assembly including:

• a bottom frame;
• a wire grid for mounting an array of multiple spring modules to the wire grid, the wire grid horizontally disposed a predetermined distance above the bottom frame and comprising a plurality of elongate wires arranged in generally perpendicular crossing relation to one another, the wires comprising a first sub-plurality of spring placement wires extending in generally spaced parallel relation to one another and a second sub-plurality of spring seating wires extending in generally parallel relation to one another and in generally perpendicular relation to the spring placement wires, the spring seating wires being arranged in a plurality of seating wire pairs with the spring seating wires of each seating wire pair disposed at a first predetermined spacing from one another and with each seating wire pair disposed at a second predetermined spacing from each seating wire pair adjacent thereto;
• and
• a plurality of wire spring modules extending between the wire grid and the bottom frame, each wire spring module comprising a top and a pair of legs, the top including first and second generally coplanar attachment segments for connecting the wire spring module to the wire grid, each of the legs being formed in a resilient spring configuration and extending in spaced relation from opposite ends of the top for connecting each end of the top with the bottom frame;
• wherein elongate wires of the wire grid are generally coplanar, straight tension wires and wherein the first and second generally coplanar attachment segments further comprise a notch and wherein each wire spring module connects to the wire grid in a generally rectangular module aperture defined by the spring seating wires of one seating wire pair and by two spring placement wires crossing the one seating wire pair, the top of the wire spring module being mounted within the module aperture so that the first attachment segment engages an inner side of the other spring seating wire, the first attachment segment abuts one of the two spring placement wires, the second attachment segment engages an outer side of the other spring seating wire, the notch of the second attachment segment engages an inner side of the one spring seating wire, and the second attachment segment abuts the other of the two spring placement wires.
