  • Patent number: 10610431
    Abstract: A movement system for use with an overhead patient lift system includes a motor. A drum is operatively coupled to the motor. The drum is configured to be selectively driven by the motor to rotate in one of a clockwise direction and a counter-clockwise direction. A lifting strap is coupled to the drum. The lifting strap is extendable and retractable with respect to a carriage of the overhead patient lifting system as the drum rotates. A manual release operatively coupled to the drum is actuatable to selectively disengage the drum from the motor to allow the lifting strap to be manually extended. Also disclosed is an overhead patient lift system including the movement system and a method for manually extending a lifting strap of an overhead patient lift system.

  • Publication number: 20190314235
    Abstract: A lift unit docking system includes a docking rail, a docking rail adapter, and a locking mechanism. The docking rail is configured to provide ingress and egress of a lift unit to and from an overhead rail, and includes a body defining a channel and an adapter receiving opening within the body. The docking rail adapter is repositionable relative to the adapter receiving opening of the docking rail and is configured to transport the lift unit into and out of the channel of the docking rail. The locking mechanism is repositionable between a locked position and an unlocked position, wherein the locking mechanism extends into the channel to block movement of a mounted lift unit toward the adapter receiving opening of the docking rail when in the locked position.

  • Publication number: 20190175427
    Abstract: A patient assisting system includes a frame having a sling assembly attachment point and a lifting arm which is movable relative to the frame and which includes a receptacle. When the sling assembly is attached to the attachment point and extends through the receptacle, a portion of the sling travels through the receptacle as the lifting arm moves relative to the frame. Another embodiment includes exactly one four bar linkage comprised of a frame having an attachment point for a sling assembly, a lifting arm having a receptacle, a lower cross arm and an upper cross arm. The lifting arm is adapted to be movable between a person-seated position and a person-standing position. The receptacle is located along the lifting arm so that motion of the lifting arm causes the receptacle to move along a curved path having a concave side which is person-facing.
