Abstract
A foundation for a bed system can include an actuator, a deck mechanism operably related to the actuator so as to be actuated between raised and lowered positions in response to actuation by the actuator, and a controller operably connected to the actuator and configured to drive the actuator to actuate the deck mechanism between a lower position and an upper position. The deck mechanism can be configured to move to a service position that is further than the upper position. The deck mechanism can expose and permit access to a serviceable component when the deck mechanism is in the service position. A method of using a foundation having a service position is also described.
Claims15
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 wherein the thigh panel is pivotably connected to the frame such that the thigh panel and the foot panel are manually moveable from a first thigh-panel position where the thigh bottom surface of the thigh panel is in contact with the first and second thigh rollers and a second thigh-panel position where the thigh bottom surface of the thigh panel is spaced apart from the first and second thigh rollers;
- 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.
