  • Publication number: 20180344553
    Abstract: A linkage assembly that connects a sling bar to a person lift apparatus includes a link body that connects to the person lift apparatus. The link body has a keyed slot extending therethrough. The keyed slot has a region of reduced dimension. An interlocking member connects to the sling bar. The interlocking member has an interlocking portion that is sized to be slidably received in the keyed slot. The interlocking portion has a region of reduced dimension such that, in an interlocked orientation, the region of reduced dimension of the interlocking portion is offset from the region of reduced dimension of the keyed slot thereby inhibiting removal of the interlocking member from the keyed slot and, in a release orientation, the region of reduced dimension of the interlocking portion is aligned with the region of reduced dimension of the keyed slot thereby allowing removal of the interlocking member from the keyed slot to disconnect the sling bar from the person lift apparatus.

  • Publication number: 20180318161
    Abstract: A motive system for a patient lifting assembly, a patient lifting assembly and a method of operating a patient lifting assembly. The motive system includes an electric motor, numerous sensors and an adaptive control unit cooperative with one another so that a memory and processor that are part of the control unit that can respectively store and execute a computer readable and executable instruction set. By comparing collected data from the sensors during operation of the motor to corresponding reference values associated with one or more motor operational parameters—such as accumulated motor wear over time or differences in operating temperature of the motor—the system can selectively adjust the maximum amount of current available for use by the motor. In this way, changes in motor efficiencies that arise with these parametric changes can be taken into consideration when determining an upper limit on how much electrical current may be delivered to the motor for a given load.

  • Patent number: 9693922
    Abstract: Disclosed is a patient lift system having a sling bar with an inductively charged integrated scale. The lift system comprises a lift apparatus, a lift strap connected at a first end to the lift apparatus, a sling bar connected to a second free hanging end of the lift strap, the sling bar having a scale with a tension load cell integrally disposed therein for measuring forces applied thereto and a power source electrically connected to the scale to provide power to the scale and load cell. An accelerometer is disposed within the sling bar to determine a tilt angle of a lift axis of the load cell relative to a vertical direction of gravitational force. Programming stored in a processor of the integrated scale calculates an accurate weight of an active load suspended from the sling bar, based on the determined tilt angle and the measured force on the load cell.
