  • Patent number: 10406044
    Abstract: A person support apparatus includes a base, wheels, a drive system, a support surface, a lift system, and a control. The control controls the drive system in response to forward/reverse forces applied thereto, and also controls the lift system in response to upward or downward forces applied thereto. In some embodiments, a controller compares a magnitude of the forward/reverse force to a magnitude of the upward/downward force and commands the drive system to drive the wheels if the magnitude of the forward/reverse force exceeds the magnitude of the upward/downward force. The control may include a user-engageable portion that is constructed to not move with respect to a force sensor when forward or reverse forces are applied to the user-engageable portion. The controller controls the drive system in response to the forward or reverse forces applied to the user-engageable portion.

  • Publication number: 20190192364
    Abstract: A patient transport apparatus comprises a base, a patient support deck, a wheel assembly, and a braking system. The wheel assembly includes a wheel and a braking mechanism. The braking system includes a linkage assembly, a manual actuator, and an electrical braking assembly. The linkage assembly is arranged to place the braking mechanism in a braked state and a released state. The manual actuator moves the linkage assembly manually to place the braking mechanism in the braked state and the released state. The electrical braking assembly includes a driving assembly that moves to a first position and to a second positing that causes the linkage assembly to place the braking mechanism in the braked state and the released state, and to a home position that allows the linkage assembly to move relative to the driving assembly to enable the braking mechanism to be manually actuated with the manual actuator.

  • Publication number: 20150157520
    Abstract: A patient support comprising a first structure, a second structure adapted to support the weight of a patient and spaced from the first structure, at least one force sensor mounted to the first structure, and a mounting structure mounting the second structure relative to the sensor, which is adapted to transfer normal forces to the sensor but absorb lateral and/or vibration forces so as not to transfer those forces to the sensor.

  • Patent number: 5636394
    Abstract: A hospital bed including a base adapted to roll over the floor, a litter disposed on the base upon which the patient rests, a lift assembly designed to selectively position the litter a selected vertical distance above the base and at least one stabilizer unit between the litter and the base. Each stabilizer unit includes a pair of rack-and-pinion assemblies that extend between the base and the litter. The pinions of the rack-and-pinion assembly are connected together to rotate in unison. Owing to the interconnection of the pinions, the rack-and-pinion assemblies are prevented from moving vertically in directions opposite to each other. This lock-out of the rack-and-pinion movement prevents the litter from moving side-to-side. The stabilizer unit thus prevents the undesirable side-to-side rocking movement of the litter.

  • Patent number: 5343581
    Abstract: A drive mechanism for a hospital bed effects relative vertical movement of a base and a patient litter. The drive mechanism includes spaced, telescoping threaded screw assemblies, which are driven by a single electric motor through a train of gears having helical teeth oriented to offset inherent frictional forces of the screw assemblies. A support for the motor and a component of the drive train are made of electrically nonconductive materials to electrically isolate the motor, and are arranged to damp vibrations produced by the motor. Two coiled electrical cords extend between the base and patient litter, and are each received in a recess in the patient litter when the patient litter is adjacent the base. A sensor arrangement provides an electrical signal indicative of the relative vertical positions of the patient litter and base, and a manual drive arrangement is provided to permit the gear train to be manually driven.

  • Patent number: 5329657
    Abstract: A hospital bed includes an articulatable patient support with a fowler portion movable between horizontal and inclined positions relative to a frame of the bed. A reversible electric drive motor is supported on the frame of the bed and, through a reduction gearing arrangement and a releasible coupling mechanism, can rotatably drive a threaded shaft. A nut engages and is held against rotation with the shaft, and a linkage arrangement couples the nut to the fowler portion to effect reciprocal movement of the fowler portion in response to reciprocal movement of the nut along the shaft. A manual release is provided on the fowler portion and, when actuated, disengages the releasible coupling mechanism so that the threaded shaft is free to rotate independently of the motor and gearing arrangement.

  • Patent number: 5172442
    Abstract: A hospital bed includes a base supported by casters, and a lift arrangement vertically movably supports a patient support section on the base. The lift arrangement includes a threaded first member secured to and projecting downwardly from the patient support section, a rotatably supported tubular second member having an internal thread which engages the threaded first member and having an external thread, and a further member which is supported on the base and has a thread engaging the external thread on the tubular second member. In one embodiment, the further member is a nut fixedly supported on the base, and a drive member rotatably supported on the base has an opening through which the second member extends and has a key portion which slidably engages an axially extending slot provided in the second member.
