Mounting apparatus for wall beds

A wall bed type assembly adapted to be mounted in a cavity and pivoted at one end between a closed vertical position and an open horizontal position, said assembly including

• a bed base for holding a mattress,
• a mounting element within the cavity, and
• a counter-balancing spring assembly connected between the bed base and mounting element,
• said counter balancing spring assembly including
• first, second, third and fourth link members, each having first and second opposed ends,
• said first link member having its first end pivotably connected to the first end of the second link member, with the second end of the second link member being pivotably connected to the mounting element,
• said third link member having its first end pivotably connected to the first link member at a point intermediate the first and second ends of the first link member and its second end pivotably connected to the first end of the fourth link member,
• said fourth link member having its end pivotably connected to the second link member at a point intermediate the first and second end of the second link member, and
• extension spring means having one end connected to the first end of the fourth link member and another end connected to the mounting element near the second end of the second link member.

A wall bed type assembly adapted to be mounted within a cavity and pivoted at one end to move between a closed vertical position and an open horizontal position, said assembly including

• a headboard having two sections,
• a bed base for holding a mattress,
• a mounting element within the cavity, and
• a counter-balancing spring assembly connected between the bed base and the mounting element, said counter-balancing spring assembly having extension spring means connected to a linkage assembly that enables the spring means to act on the bed base to provide a counter-balancing force as the bed is being opened and closed, but effectively neutralizes the counter-balancing force when the bed is open,
• linkage means connecting the mattress support at said one end to the mounting element, said linkage means including a plurality of arm members which move the wall bed from the wall to position said one end beyond the cavity and elevate the bed base to a predetermined height above the floor which generally is equal to the head of a conventional bed, and
• means for folding one of the headboard sections so that it lies on the sleeping surface of the mattress upon moving the wall bed to the closed position and for unfolding said one section to position said one section either at a right angle with respect to the sleeping surface of the mattress or tilted rearwardly with respect to said sleeping surface,
• said means for folding and unfolding the headboard having a rigid arm which is attached and detached to change its effective length to thereby control the angular relationship of said one section to the sleeping surface.
