Adjustable furniture
The invention provides an adjustable bed comprising a frame ( 20 ) and at least one adjustable body support section including at least an adjustable backrest support section ( 12 ) pivotally mounted for angular adjustment with respect to the frame. The frame comprises at least two hinged sections ( 20 a, 20 b ) including a head end sub-assembly configured as an upper body supporting section on which the backrest support section is mounted, and a separate toe end sub-assembly configured as a lower body supporting section hinged with respect to the upper body supporting section. Actuator means ( 40 ) is disposed within at least the upper body section for angular adjustment of the adjustable body support section. The head end sub-assembly and the toe end sub-assembly are capable of being folded together to reduce the length dimension of the bed for transportation and/or storage purposes and subsequently unfolded to provide a full length adjustable bed.
1. An adjustable bed, comprising:
a frame;
a pair of frame sections including a first head end sub-assembly frame section configured as an upper body supporting section upon which an adjustable backrest support panel and a non-adjustable intermediate body support panel are mounted upon upper surface portions of said first head end sub-assembly frame section, and a second toe end sub-assembly frame section configured as a lower body supporting section upon which a lower body support panel is mounted upon an upper surface portion of said second toe end sub-assembly frame section;
a hinge mechanism having a first hinge plate fixedly secured to said non-adjustable intermediate body support panel of said first head end sub-assembly frame section and a second hinge plate fixedly secured to said lower body support panel of said second toe end sub-assembly frame section such that said first head end sub-assembly frame section and said second toe end sub-assembly frame section are hingedly connected directly to each other around a single hinge axis whereby said first head end sub-assembly frame section and said second toe end sub-assembly frame section are capable of being folded toward each other so as to attain a folded state, with said upper surface portion of said first head end sub-assembly frame section and said upper surface portion of said second toe end sub-assembly frame section being disposed in a face-to-face oppositely disposed relationship with respect to each other so as to minimize the length dimension of said bed, or the width dimension or profile of said bed as considered when said bed is disposed in said folded state, for transportation and/or storage purposes, and subsequently capable of being unfolded away from each other so as to again provide a full length adjustable bed;
said adjustable backrest support section, disposed upon said first upper head end sub-assembly frame section, is pivotally mounted upon said first head end sub-assembly frame section for angular movement with respect to said first head end sub-assembly frame section;
an actuator is operatively connected to said adjustable backrest support section so as to pivotally adjust said adjustable backrest support section to various different angular positions with respect to said first head end sub-assembly frame section;
wherein said first head end sub-assembly frame section and said second toe end sub-assembly frame section are disposed within a horizontal plane when said first head end sub-assembly frame section and said second toe end sub-assembly frame section are unfolded away from each other so as to again provide a full length adjustable bed; and
said first head end sub-assembly frame section comprises a frame segment which is inclined downwardly, relative to said horizontal plane within which said first head end sub-assembly frame section and said second toe end sub-assembly frame section are disposed when said first head end sub-assembly frame section and said second toe end sub-assembly frame section are unfolded away from each other so as to again provide a full length adjustable bed, and to which one end of said actuator is attached such that said actuator is always disposed beneath said adjustable backrest support section so as to therefore be capable of applying an upwardly inclined force in order to move said adjustable backrest support section between fully lowered and fully raised positions.
2. An adjustable bed as claimed in claim 1 wherein said non-adjustable intermediate body support panel serves to provide at least part of a fixed seat section of the bed.
3. An adjustable bed as claimed in claim 2 wherein said lower body support panel of said second toe end sub-assembly frame section is non-adjustable.
