Adjustable bed with side rail

An adjustable bed, said bed comprising:

• a base frame defining a head end and a foot end;
• a mattress frame including a head section and a lower section pivoted to said head section;
• mounting means on the base frame for mounting the mattress frame to said base frame and permitting the head section to tilt with respect to said base frame and said lower section;
• and
• positioner means interconnecting said head section and said lower section for positioning and locking the angular relationship of said sections, said positioner means including:
• a first link having an end fixed to said head section and a free end, a bracket fixed to said lower section, an elongated rod having a free end and another end pivoted to said bracket, and lock means pivoted to said free end of said first link for locking said rod free end with respect to said first link and, hence, said head section with respect to said lower section, said lock means including actuator means for permitting actuation of said lock means in two alternative modes, and wherein said lock means comprises:
• a positioner housing defining a pair of generally opposed apertures;
• an actuator pin and cable with first and second ends extending through said housing apertures;
• a pair of lock plates disposed within said housing, each plate defining a lock aperture through which said elongated rod extends;
• spring means within said housing for urging an edge of each of said lock apertures into engagement with said elongated rod;
• and
• a cam on said cable intermediate said ends and engaging said lock plates for moving the lock aperture edges out of engagement with said elongated rod so that a free end of said elongated rod may move with respect to said housing.

An occupant operated linear positioner for use in an adjustable bed, said positioner means comprising:

• a positioner housing defining a pair of generally opposed apertures;
• an actuator pin and cable, said pin extending through one of said positioner housing apertures and said cable extending through the other of said apertures;
• a pair of lock plates disposed within said housing, each plate defining a lock aperture through which a positioner rod extends;
• spring means within said housing for urging the edge of each of said lock apertures into engagement with said rod;
• a cam operatively connected to said cable and engaging said lock plates for moving the lock aperture edges out of engagement with said rod so that said rod may move with respect to said housing;
• first actuator means connected to said cable for pulling said cable and rotating said cam to release said rod;
• and
• second actuator means on said housing and engaging said pin for pushing said pin into said housing and rotating said cam to release said rod.
