Abstract
Spring plate furniture wherein a planar spring is capable of resiliently supporting loads and/or resiliently being manipulated into a furniture form, the planar spring cut or molded so that usually continuous serpentine members extend between support points at which the cross-section or width of the serpentine members increases when the spring plate is to be subjected to loads and restrained from rotation.
Claims17
In a planar, spring-type load support panel, for use in furniture or the like, the combination comprising:
- a) the panel extending longitudinally and laterally, and having peripheral edges,
- b) the panel having panel support regions longitudinally inwardly of said longitudinally spaced edges,
- c) and the panel having a load support region longitudinally intermediate to said panel support regions,
- d) said intermediate load support region defining multiple slits extending in generally parallel relation,
- e) said intermediate region defining serpentine load supporting, flat spring structure,
- f) said slits extending generally laterally,
- g) the longitudinal spacing between successive laterally extending slits increasing toward said panel support regions.
In a planar, spring-type, load support panel, for use as in furniture or the like, the combination comprising:
- a) the panel extending longitudinally and laterally, and having bounding structure with peripheral edges,
- b) there being longitudinally extending, laterally spaced, narrow slots A and C through the panel, the slots extending in generally parallel relation, the slots A and C spaced from said peripheral edges,
- c) there also being laterally extending, relatively longitudinally spaced narrow slits D and E through the panel, the slits extending in generally parallel relation,
- d) certain D slits intersecting the A slot and extending toward the C slot, and certain E slits intersecting the C slot and extending toward the A slot,
- e) said A and C slots and D and E slits bounded by said bounding structure,
- f) the longitudinal spacing between successive laterally extending slits increasing toward panel opposite ends which are longitudinally spaced.
In a uniformly thick planar, load support panel, for use as in furniture or the like, the combination comprising:
- a) the panel extending lengthwise and widthwise, and having peripheral edges,
- b) the panel having an outer support region inwardly of at least one of said lengthwise edges,
- c) and the panel having an intermediate region bounded by said edges,
- d) said intermediate region defining multiple slits extending in generally parallel relation, widthwise of the panel, alternate slits starting from each side edge and terminating short of the other side edge,
- e) said intermediate region defining serpentine load supporting, flat spring structure,
- f) the spacing between successive slits, lengthwise of the panel, increasing toward said outer support region.
A uniformly thick panel extending longitudinally and laterally with a surface adapted to become resilient either to support applied loads or to deform or both, such adaptation consisting of laterally oriented and extending slits extending from alternate longitudinal edges terminating short of opposite edges, wherein longitudinal spacing of successive slits decreases away from longitudinally spaced panel support regions.
