Abstract
A spring wire core for use in bedding mattresses and/or upholstered furniture cushions and the like comprised of a pair of half units. Each half unit includes a surface portion and a plurality of springs projecting in one direction from the surface portion. Connecting elements are provided to enable a pair of half units, one inverted relative to the other, to be connected together forming a wire core with two spaced surface portions. Preferably, the spring portions are configured to enable a plurality of the half units to be nestably stacked one upon another to enable efficient shipping of the half units without compression of the spring portions.
Claims23
A spring wire core comprising:
- a first half unit including means forming a first surface portion and means forming a plurality of spring portions projecting from one side of said first surface portion;
- a second half unit including means forming a second surface portion and means forming a plurality of spring portions projecting from one side of said second surface portion;
- and
- means for joining said first and second half units together with said second half unit being inverted relative to said first half unit and with said spring portions of one half unit projecting toward the surface portion of the other half unit thereby forming said wire core with spaced first and second surface portions.
A vertical stack of spring wire core half units, each half unit having means forming a surface portion, means forming spring portions projecting from one side of said surface portion and connector means for connecting two of said half units together with one of said half units inverted relative to the other of said two half units, said spring portions tapering away from said surface portions and being open at said surface portions whereby the spring portions of one half unit can be nested into the spring portions of the half unit therebelow in said stack of half units.
A spring wire core comprising:
- a first half unit including a plurality of first spring elements having top portions generally lying in a first plane and spring portions extending away from said first plane in one direction, and first lacing wires in said first plane connected to said top portions of said first spring elements to join said first lacing wires and said first spring elements together, said first lacing wires and said top portions forming a first surface portion for said wire core;
- a second half unit including a plurality of second spring elements having top portions generally lying in a second plane and spring portions extending away from said second plane in one direction, and second lacing wires in said second plane connected to said top portions of said second spring elements to join said second lacing wires and said second spring elements together, said second lacing wires and said top portions forming a second surface portion for said wire core;
- and
- means for joining said first and second half units together with said second half unit being inverted relative to said first half unit and with said spring portions of each half unit projecting toward the surface portion of the other half unit thereby forming said wire core with space first and second surface portions and said spring portions therebetween.
A spring wire core for use in furniture having spaced top and bottom surface portions, said spring wire core comprising:
- a first half unit having means forming a surface portion and means forming a plurality of spring elements having spring portions extending in one direction from said surface portion, said spring elements having spring portions which taper away from said surface portion and which are open at said surface portion whereby a plurality of said half units can be nestably stacked with the spring portions of one half unit being inserted into the spring portions of the half unit therebelow;
- a second half unit identical to said first half unit;
- means for joining said first and second half units together with said second half unit being inverted relative to said first half unit with the spring portions of one half unit extending toward the surface portion of the other half unit thereby forming said wire core with spaced top and bottom surface portions.
