Abstract

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies ( 145 ), with each spring assembly including at least one spring ( 134 ) and a spring cap ( 144, 150, 161, 164, 171, 184, 194, 204 ). Each spring cap has at least one first attachment fitting ( 168, 178, 174, 186, 196 ) and at least one second attachment fitting ( 169, 180, 176, 187 ) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

24 . The mattress of claim 21 with the spring of each spring assembly removable from the spring cap.

25 . The mattress of claim 21 wherein the at least one first attachment fitting comprises a side post ( 178 ) on the spring cap and the at least one second attachment fitting comprises a side socket ( 180 ) on the spring cap opposite from the side post.

26 . The mattress of claim 21 wherein the at least one first attachment fitting comprises a side tab ( 168 ) on the spring cap and the at least one second attachment fitting comprises a side slot ( 169 ) on the spring cap opposite from the side tab.

27 . The mattress of claim 21 wherein the at least one first attachment fitting comprises a hook ( 174 ) on the spring cap and the at least one second attachment fitting comprises a notch ( 176 ).

28 . The mattress of claim 21 wherein the at least one first attachment fitting comprises a pin ( 186 , 196 ) on the spring cap and the at least one second attachment fitting comprises a pin hole ( 187 , 199 ) aligned on a chord of the spring cap opposite from the side tab.

29 . The mattress of claim 28 with the pin hole ( 199 ) in a boss ( 197 ), further including a tab ( 198 ) pivotally attached to the boss ( 197 ), with the tab having a latch hook ( 202 ) engageable onto a lip ( 203 ) on the boss.

30 . The mattress of claim 21 wherein the at least one first attachment fitting comprises a pin ( 186 , 196 ) on the spring cap and the at least one second attachment fitting comprises a pin hole ( 187 , 199 ) in a split boss ( 206 ), with a release tab ( 205 ) joined to one side of the split boss.

31 . The mattress of claim 21 further including a plurality of bosses ( 220 ) on a bottom side of the top pad, and with the top end of each spring around one of the plurality of bosses.

32 . The mattress of claim 31 wherein each of the bosses is D-shaped, and each spring has a top segment ( 159 ) parallel to a straight surface of the D-shaped boss.

33 . The mattress of claims 31 further including a plurality of recesses ( 222 ) in the bottom side of the top pad, and with the top end of each spring projecting into one of the plurality of recesses.

34 . The mattress of claims 21 with each spring assembly separable into a spring and a spring cap, and with the springs stackable within each other in a spring column ( 232 ), and with the spring caps stackable on top each other into a spring cap column( 234 ), and with the spring column inside of the spring cap column.

35 . A mattress comprising:
a flat webbing ( 154 , 156 ); a plurality of spring caps ( 150 , 161 ) attachable to the flat webbing; a plurality of springs ( 134 ) with each spring attachable to a spring cap; and a top pad on top of a top end of substantially each spring.

36 - 37 . (canceled)

38 . The mattress of claim 35 with each spring cap comprising a rigid plastic or metal element having a flat elongated base ( 152 ) attached to the flat webbing and first and second raised arc sections ( 151 ) at opposite ends of the flat base, with the arc sections having a groove ( 153 or 157 ) for engaging onto a bottom coil ( 160 ) of one of the plurality of springs to attach that spring to the spring cap.

39 .
