Abstract

Abstract An article of furniture adapted to be used selectively as a chair or as a recliner, and which is particularly suitable for use by arthritics or others who because of infirmity have difficulty in becoming seated in or arising from an article of furniture such as a chair or a recliner. The chair-recliner includes a supporting framework and a chair-recliner body mounted on the framework. The chair-recliner body comprises a deformable resilient member which extends for the length of the chair-recliner body, the resilient member being connected to its opposite longitudinal ends to the framework. The length of the resilient member exceeds the distance between the locations at which the ends thereof are connected to the framework, whereby the resilient member assumes a normally vertically extending arch-like arcuate shape when the chair-recliner body and the resilient member which forms a part thereof are in an "at rest" predeformation position. The arch-like arcuate predeformation shape of the chair-recliner body facilitates the movement of an infirm person into seated or reclining position. The chair-recliner body and the resilient member are deformable by the body weight of a user from the arch-like arcuate predeformation shape selectively into a chair shape or into a recliner shape in accordance with the positioning of the user's body weight on the chair-recliner body. The movement of the chair-recliner body into deformed position corresponding to the seated or to the reclining position of the chair-recliner stores energy in the deformable resilient member of the chair-recliner body, which aids the user in arising from the chair-recliner when desired. A suitable latching means is provided to retain the deformable body of the chair-recliner in its deformed position, such as the seated or reclining position, to prevent unintentional reversion of the chair-recliner body to its predeformation position. The latching means is released when the user desires to arise from the chair-recliner.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 189 words
An article of furniture adapted to be used selectively as a chair or as a recliner, comprising a vertically inclined supporting framework including a normally lower end and a normally upper end, leg means carried by said framework for supporting said framework in vertically inclined position, a chair-recliner body mounted on said framework, said body comprising a deformable resilient member, means connecting the respective opposite longitudinal ends of said deformable resilient member to said framework at locations respectively contiguous said normally lower end and contiguous said normally upper end of said framework, the length of said resilient member exceeding the distance between said locations at which said ends of said resilient member are connected to said framework, whereby said body and said resilient member assume a normally vertically extending arch-like arcuate shape when said body and said resilient member are in an "at rest" predeformation position, said body and said resilient member being deformable by the weight of a user from said arch-like arcuate shape selectively into a chair shape or into a recliner shape in accordance with the positioning of the user's body weight on said chair-recliner body.
Claim 2
Dependent Claim 189 words
An article of furniture adapted to be used selectively as a chair or as a recliner, comprising a vertically inclined supporting framework including a normally lower end and a normally upper end, leg means carried by said framework for supporting said framework in vertically inclined position, a chair-recliner body mounted on said framework, said body comprising a deformable resilient member, means connecting the respective opposite longitudinal ends of said deformable resilient member to said framework at locations respectively contiguous said normally lower end and contiguous said normally upper end of said framework, the length of said resilient member exceeding the distance between said locations at which said ends of said resilient member are connected to said framework, whereby said body and said resilient member assume a normally vertically extending arch-like arcuate shape when said body and said resilient member are in an "at rest" predeformation position, said body and said resilient member being deformable by the weight of a user from said arch-like arcuate shape selectively into a chair shape or into a recliner shape in accordance with the positioning of the user's body weight on said chair-recliner body.
Claim 3
Dependent Claim 18 words
An article of furniture as defined in claim 1 in which said resilient member is a spring assembly.
Claim 4
Dependent Claim 90 words
An article of furniture as defined in claim 2 in which said spring assembly comprises a plurality of individual springs, said individual springs respectively extending in a direction lengthwise of the respective springs from contiguous the normally upper end of said framework to contiguous the normally lower end of said framework, means interconnecting said plurality of individual springs in assembled relation to each other, and means anchoring said spring assembly to said framework contiguous said normally upper end of said framework and contiguous said normally lower end of said framework.
Claim 5
Dependent Claim 23 words
An article of furniture as defined in claim 3 in which said plurality of individual springs are of the serpentine or zig-zag type.
Claim 6
Dependent Claim 21 words
An article of furniture as defined in claim 3 in which said plurality of individual springs are rods of spring steel.
Claim 7
Dependent Claim 21 words
An article of furniture as defined in claim 1 in which said resilient member comprises a sheet of acrylic plastic material.
Claim 8
Dependent Claim 33 words
An article of furniture as defined in claim 1 in which an end of said resilient member is adjustably connected to said framework whereby to permit varying the tension on said resilient member.
Claim 9
Dependent Claim 72 words
An article of furniture as defined in claim 1, including latching means comprising cooperating elements mounted on said framework and on said chair-recliner body, said cooperating elements being engageable with each other when said chair-recliner body is in a deformed position corresponding either to the seated or to the reclining position of said chair-recliner body, whereby to retain said chair-recliner body in said deformed position against unintentional reversion to said predeformation position.
