Adjustable Foundation with Service Position

An adjustable mattress foundation comprising:

• a set of legs;
• a frame coupled to and supported by the set of legs;
• a head panel hingedly coupled to and supported by the frame, the head panel comprising a first head edge and a second head edge opposite the first head edge, the head panel comprising a head bottom surface facing toward the frame and a head top surface facing away from the frame;
• a thigh panel hingedly coupled to and supported by the frame, the thigh panel comprising a first thigh edge and a second thigh edge opposite the first thigh edge, the thigh panel comprising a thigh bottom surface facing toward the frame and a thigh top surface facing away from the frame;
• a foot panel hingedly coupled to and at least partially supported by the thigh panel, the foot panel comprising a first foot edge and a second foot edge opposite the first foot edge, the foot panel comprising a foot bottom surface facing toward the frame and a foot top surface facing away from the frame;
• first and second linkage arms each having a first end pivotably connected to the frame and a second end pivotably connected to the foot bottom surface of the foot panel;
• a foot and thigh actuation assembly comprising:
• a horizontal shaft;
• a first thigh lever arm extending from the horizontal shaft and comprising a first thigh roller configured to abut a first portion of the thigh panel;
• a second thigh lever arm extending from the horizontal shaft and comprising a second thigh roller configured to abut a second portion of the thigh panel;
• third and fourth lever arms extending from the horizontal shaft that are shorter than the first and second thigh lever arms;
• and
• a thigh actuator with a first end coupled to the frame and a second end coupled to distal ends of both of the third and fourth lever arms, the thigh actuator configured to push both of the third and fourth lever arms to move both of the first and second thigh lever arms to raise and lower both of the thigh panel and the foot panel by rolling the first and second thigh rollers against the thigh panel;
• and
• a head actuation assembly comprising:
• a first head lever arm comprising a first head roller configured to abut a first portion of the head panel;
• a second head lever arm comprising a second head roller configured to abut a second portion of the head panel;
• and
• a head actuator coupled between the frame and the first and second head lever arms, the head actuator configured to move both of the first and second head lever arms to raise and lower the head panel by rolling the first and second head rollers against the head panel.

An adjustable mattress foundation comprising:

• a foundation frame;
• a set of deck panels configured to support a mattress, the set of deck panels comprising:
• a first deck panel configured to be raised and lowered relative to the foundation frame;
• a second deck panel, the second deck panel rigidly connected to the foundation frame proximal the first deck panel;
• and
• a third deck panel configured to be raised and lowered relative to the foundation frame, the third deck panel comprising an edge that is positioned nearest an end of the foundation frame, the second deck panel positioned between the first deck panel and the second deck panel;
• an actuation system configured to raise and lower the first deck panel and the third deck panel between an upper position and a lower position;
• and
• a linkage arm pivotably connected to a bottom surface of the third deck panel, the linkage arm comprising a first end, a second end, a first arm portion proximate the first end, and a second arm portion proximate the second end, and a bend portion between the first arm portion and the second arm portion, the linkage arm extending from the first end toward the second end such that the second end is closer to the end of the foundation frame than is the first end, the second end of the linkage arm pivotably connected to the third deck panel, the linkage arm configured to move the third deck panel to a service position that is raised further than the upper position in response to a user manually moving the third deck panel to the service position.
