Abstract
Abstract A structure for supporting a reclining and lying means comprises a lath grating (14) formed from a plurality of transverse laths (13) which is arranged on a support structure (10,20) having at least two longitudinally oriented, spaced longitudinal beams (spring bodies) (12, 12'; 22, 22') acting resiliently at right angles to their loading and which are assembled into a structural unit with approximately regularly arranged spring elements (13) and lath grating (14) operatively connected by a cover which holds the components together.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
A structure for supporting a reclining human body comprising a plurality of elongated, substantially parallel, spaced apart longitudinally extending spring beam members placeable on a rigid support surface, each of said spring beam members being yieldable and elastic in a direction substantially perpendicular to their longitudinal dimension; a plurality of transverse lath members for receiving the reclining body, each of said lath members resting on and being supported at the ends of said lath members by said spring beam members without the lath members and spring beam members being fixedly attached therebetween, said lath members being movable vertically without significant flexing in response to the weight of said body as said spring beam members yield elastically; and a flexible support sheet extending generally between opposite ends of said lath members and engaging said spring beam members and holding said spring and lath members together in a resiliently responsive, stable assembly, said support sheet having means for removably attaching said sheet to said opposite ends of said lath members.
Claim 2
Dependent Claim
168 words
A structure for supporting a reclining human body comprising a plurality of elongated, substantially parallel, spaced apart longitudinally extending spring beam members placeable on a rigid support surface, each of said spring beam members being yieldable and elastic in a direction substantially perpendicular to their longitudinal dimension; a plurality of transverse lath members for receiving the reclining body, each of said lath members resting on and being supported at the ends of said lath members by said spring beam members without the lath members and spring beam members being fixedly attached therebetween, said lath members being movable vertically without significant flexing in response to the weight of said body as said spring beam members yield elastically; and a flexible support sheet extending generally between opposite ends of said lath members and engaging said spring beam members and holding said spring and lath members together in a resiliently responsive, stable assembly, said support sheet having means for removably attaching said sheet to said opposite ends of said lath members.
Claim 3
Dependent Claim
39 words
A structure according to claim 1 wherein said means for removably attaching said sheet to said opposite ends of said lath members includes pockets formed along opposite edges of said sheet to receive the ends of said lath members.
Claim 4
Dependent Claim
39 words
A structure according to claim 2 wherein said support sheet passes from the pockets at one ends of said lath members underneath and against said spring beam members to the pockets at the other ends of said lath members.
Claim 5
Dependent Claim
31 words
A structure according to claim 3 and further comprising a second flexible sheet extending across upper surfaces of said lath members, said second sheet being detachably connected to said support sheet.
Claim 6
Dependent Claim
32 words
A structure according to claim 4 and further comprising means defining flexible tubes for receiving said spring beam members, said means defining said tubes being substantially permanently attached to said support sheet.
Claim 7
Dependent Claim
49 words
A structure according to claim 5 wherein each of said spring beam members is divided along its length into a plurality of end-to-end zones each having a selected support hardness different from the other zones, the zone at a head-supporting portion of the structure having the stiffest support hardness.
Claim 8
Dependent Claim
29 words
A structure according to claim 6 wherein each of said spring beam members is made from elastic foam and has a cross-section in the shape of a regular polygon.
Claim 9
Dependent Claim
28 words
A structure according to claim 6 wherein each of said spring beam members is made from elastic foam and has a cross-section in the shape of a rectangle.
Claim 10
Dependent Claim
28 words
A structure according to claim 6 wherein each of said spring beam members is made from elastic foam and has a cross-section in the shape of a circle.
Claim 11
Dependent Claim
30 words
A structure according to claim 6 wherein each of said spring beam members is made from elastic foam and has a cross-section in the shape of a hollow tubular member.
Claim 12
Dependent Claim
23 words
A structure according to claim 1 and including loops means for interconnecting said ends of said lath members and said spring beam members.
Claim 13
Dependent Claim
13 words
A structure according to claim 1 wherein said spring beam members are inflatable.
