  • Lift system with a stowable support assembly
    Patent number: 11717457
    Abstract: A lift system includes a hoist module, a support assembly which is movable relative to the hoist module, and a control system. The control system is adapted to enable a user to a) issue an operational command which causes the support assembly to move to an operational destination, and b) issue a stowage command which causes the support assembly to move to a stowage destination. The control system is also adapted to A) disregard the stowage command provided at least one condition is satisfied and/or B) encumber issuance of the stowage command Equivalently, the control system adaptation is to A1) disregard the stowage command provided at least one stowage contraindication condition is satisfied or A2) not disregard the stowage command provided at least one stowage noncontraindication condition is satisfied and/or B) encumber issuance of the stowage command.

  • Switch assemblies, rail-mounted lift systems, and rail-mounted lift units having emergency stop devices
    Patent number: 11679962
    Abstract: A switch assembly for a lift unit includes a switch, an emergency stop device, and a reset actuator. The switch is arranged to move between a closed position, wherein the switch electrically couples a lift motor of the lift unit to an energy source, and an open position, wherein the switch electrically decouples the lift motor from the energy source. The emergency stop device is coupled to the switch and arranged to move the switch from the closed position to the open position. The reset actuator is coupled to the switch and arranged to move the switch from the open position to the closed position, wherein the reset actuator is controllable to move the switch from the open position to the closed position.

  • Overhead lift systems and methods
    Patent number: 11672716
    Abstract: An overhead lift system may include a motor and a lift strap connected to the motor. The motor raises and lowers the lift strap. A hand controller may be communicatively connected to the motor. The hand controller includes a force sensor associated with the body of the hand controller such that force applied to the body is detected with the force sensor. An orientation sensor may also be arranged within the body and determines an orientation of the hand controller. A control unit may be communicatively connected with the motor, the force sensor, and the orientation sensor. The control unit detects a force applied to the hand controller with the force sensor, determines a direction of motion of the hand controller with the orientation sensor, and provides a signal to the motor to raise or lower the lift strap based on the force and orientation of the hand controller.

  • DETERMINING LIFTING EVENTS USING SENSORS FOR PERSON LIFTING APPARATUSES
    Publication number: 20200085657
    Abstract: A method of determining a lifting event of a person lifting apparatus is provided. The method includes receiving one or more of (i) current load information from a current measuring device that is indicative of current drawn by an actuator operatively connected to a lifting strap of the person lifting apparatus; (ii) strap position information from a position sensor that is indicative of a paid out length of the lifting strap of the person lifting apparatus; and (iii) weight information from a weight sensor that is indicative of a load supported by the lifting strap of the person lifting apparatus. A computing device comprising a processor using logic is used to identify at least one of a raising event, a repositioning event and a lowering event based on the one or more of the current load information, strap position information and weight information.
