Ambulatory care chair

A chair comprising

• a base frame,
• an intermediate frame coupled to the base frame for pivoting movement about a horizontal transverse axis thereon,
• an articulated patient support including longitudinally spaced back, seat, and leg sections supported with respect to the intermediate frame for movement relative to one another and relative to the intermediate frame,
• a control plate rotatably coupled to the intermediate frame for rotation about the horizontal transverse axis and coupled to the back, seat, and leg sections so that rotation of the control plate relative to the intermediate frame moves the back, seat, and leg sections relative to the intermediate frame.

A chair comprising

• an intermediate frame coupled to the base frame for pivoting movement relative to the base frame about a horizontal transverse axis thereon,
• an articulated patient support coupled to the intermediate frame, the patient support including back, seat, and leg sections, and
• a control assembly coupling each of the back, seat, and leg sections to the intermediate frame, the control assembly being movable to establish the position of the back, seat, and leg sections relative to the intermediate frame, the control assembly including a plurality of links, at least one of the links being coupled to the intermediate frame to pivot about the horizontal transverse axis relative to the intermediate frame and relative to the base frame.

A chair for supporting a patient above a floor, the chair comprising

• a base frame,
• an intermediate frame coupled to the base frame for pivoting movement relative to the base frame about a generally horizontal transverse axis,
• an articulated patient support mounted to the intermediate frame, the patient support including longitudinally spaced back and seat sections mounted to the intermediate frame for movement relative to one another and relative to the intermediate frame, the back and seat sections being movable relative to the base frame about the horizontal transverse axis,
• a control assembly pivotably coupling the articulated patient support to the intermediate frame, the control assembly including a control plate coupled to the intermediate frame for rotation about the transverse horizontal axis and coupled to each of the back and seat sections so that the orientation of any one of the back section, the seat section, and the control plate relative to the intermediate frame establishes the orientation relative to the intermediate frame of the other of the back section, the seat section, and the control plate,
• a locking mechanism coupling the control plate to the intermediate frame, the locking mechanism being lockable to block rotation of the control plate relative to the intermediate frame thereby blocking movement of the back and seat sections relative to the intermediate frame, and the locking mechanism being releasable to allow rotation of the control plate relative to the intermediate frame thereby allowing movement of the back and seat sections relative to the intermediate frame, and
• a shaft fixed to the control plate and coupled to the intermediate frame for rotation, relative to the intermediate frame about the horizontal transverse axis and a tab fixed to the shaft and extending radially outwardly from the horizontal transverse axis, the locking mechanism being connected to the tab and being coupled to the control plate through the tab and the shaft.

A chair for supporting a patient above a floor, the chair comprising

• a base frame including a lower frame, a staging frame, and drive means for raising and lowering the staging frame relative to the lower frame,
• an intermediate frame coupled to the staging frame for pivoting movement relative to the staging frame about a generally horizontal transverse axis,
• an articulated patient support mounted to the intermediate frame, the patient support including longitudinally spaced back and seat sections mounted to the intermediate frame for movement relative to one another and relative to the intermediate frame, the back and seat sections being movable relative to the base frame about the horizontal transverse axis, and
• a releasable lock coupling the intermediate frame to the staging frame to block pivoting movement of the intermediate frame about the horizontal transverse axis relative to the staging frame.

A chair for supporting a patient above a floor, the chair comprising

• a base frame,
• an intermediate frame coupled to the base frame for pivoting movement relative to the base frame about a generally horizontal transverse axis,
• an articulated patient support mounted to the intermediate frame, the patient support including longitudinally spaced back and seat sections mounted to the intermediate frame for movement relative to one another and relative to the intermediate frame, the back and seat sections being movable relative to the base frame about the horizontal transverse axis,
• casters mounted to the base frame and engaging the floor and a wheel mounted to the base frame for vertical movement relative to the base frame between a brake-steer position engaging the floor and a neutral position spaced apart from the floor,
• means for braking the casters to block the rotation of the casters relative to the base frame when the braking means is braked and allowing rotation of the casters relative to the base frame when the braking means is released, and
• a brake-steer pedal pivotably coupled to the base frame for movement between a braking position and a steering position, the brake-steer pedal being coupled to the braking means to brake the braking means when the brake-steer pedal is in the braking position and to release the braking means when the brake-steer pedal is in the steering position, the brake-steer pedal also being coupled to the wheel to control the vertical movement of the wheel relative to the base frame.

A chair for supporting a patient above a floor, the chair comprising

• a base frame,
• an intermediate frame coupled to the base frame for pivoting movement relative to the base frame about a generally horizontal transverse axis, and
• an articulated patient support mounted to the intermediate frame, the patient support including longitudinally spaced back and seat sections mounted to the intermediate frame for movement relative to one another and relative to the intermediate frame, the back and seat sections being movable relative to the base frame about the horizontal transverse axis, the back section being movable to a generally horizontal table position,
• casters mounted to the base frame and engaging the floor,
• means for braking the casters to block rotation of the casters relative to the base frame when the braking means is braked and for allowing rotation of the casters relative to the base frame when the braking means is released,
• a pedal wing pivotably coupled to the base frame for movement relative to the base frame between a downward braking position and an upward steering position and coupled to the braking means so that the braking means is braked when the pedal wing is in the braking position and braking means is released when the pedal wing is in the steering position, the pedal wing extending rearwardly and outwardly from the base frame so that the pedal wing is accessible when the back section is in the table position, and
• a shaft fixed to the pedal wing and rotatably coupled to the base frame so that the shaft pivotably couples the pedal wing to the base frame, the shaft defining a pivot axis and being formed to include a steering portion extending upwardly form the pivot axis when the pedal wing is in the braking position so that applying a contact force to the steering portion pivots the pedal wing to the steering position, the steering portion being positioned to lie beneath the back section when the back section is in the table position to minimize access to the steering portion when the back section is in the table position.

A chair comprising

• a base frame,
• an intermediate frame coupled to the base frame for pivoting movement about a horizontal transverse axis thereon,
• a patient support including a plurality of sections, and
• a control assembly coupling the plurality of sections to the intermediate frame, the control assembly being movable to change the position of the plurality of sections relative to the intermediate frame, the control assembly including at least one link that is coupled to the intermediate frame to pivot about the horizontal transverse axis relative to the intermediate frame.
