Adjustable articulated bed

A power drive module for an adjustable articulated bed that may be assembled and disassembled and nested in a bed frame for adjusting an articulated mattress which includes back, center, thigh and lower leg sections, comprising:

• a pair of central support sections having apertures therein whose periphery is provided with an alignment flat;
• a lateral support member having a flatted surface which aligns and joins said central support sections to form the sides of said power module;
• said central support sections having hanging means for supporting said power drive module upon said frame;
• back supporting means pivotally attached to one end of said central support sections for supporting said back section of said articulated mattress;
• said central support sections supporting said center section of said articulated mattress;
• thigh supporting means pivotally attached to the other end of said central support sections for supporting said thigh section of said articulated mattress;
• lower leg supporting means pivotally attached to the end of said thigh supporting means opposite the end thereof attached to said central support sections for supporting said lower leg portion of said articulated mattress;
• connecting means having apertures therein whose peripheries are provided with an alignment flats aligned by and mounted on said lateral support member;
• and
• motor means pivotally mounted upon said aligned connecting means between said central support sections for raising and lowering said back supporting means and said thigh supporting means wherein the raising of said thigh supporting means raises said lower leg supporting means, for adjusting said articulated mattress independent of said frame.

A power drive module for use in an articulated adjustable bed that may be assembled and disassembled and mounted within a bed frame for support of an articulated mattress having back, center and leg sections, comprising:

• a pair of central support sections forming the side support for said power drive module to support said center section of said mattress having apertures therein whose periphery has an alignment flat;
• a lateral support member having at least one alignment flat connecting said central support sections and forming the cross support for said power drive module;
• back support means pivotally mounted to one end of each of said central support sections to support said back section of said mattress;
• leg support means pivotally mounted to the other end of each of said central support sections to support said leg section of said mattress;
• said pivotally mounted back and leg support means mounted at more than one pivot point to said pair of central support section to strengthen said power drive module;
• connecting means having apertures therein with alignment flats for aligned mounting upon said later support member;
• drive motor means pivotally connected to said connecting means for driving said back and leg support means;
• and
• said pivotally mounted back and leg support means free of any mounting upon said bed frame whereby any bed frame may be used to create an adjustable bed.

An adjustable articulated bed comprising:

• a frame;
• an articulated mattress;
• a separate power drive module removably nested within said frame to support said articulated mattress;
• a pair of central support sections forming the side supports of said power drive module each having an aperture therein whose periphery is provided with an alignment flat;
• a lateral support member having a flatted cross section passing through said apertures in said central sections for joining said central sections in parallel alignment with said flats;
• a skirt enclosing said frame;
• and
• stand off means mounted between said frame and said skirt constructed from an absorbent material to mechanically isolate said skirt from said frame thereby reducing noise and vibration as said articulated bed is adjusted.
