摘要： A transfer chair has a chair frame, a seat, wheels, and a lift arm which has an articulated path between home and target positions. The lift arm is articulated such that a lifting bridle attached to a distal end of the lift arm is maintained in a constant angular orientation with respect to the chair frame during movement. The lift arm is constructed using four links which are pivotally connected end-to-end and which can be folded to a stowed position within the chair frame. An actuation mechanism uses a lead-screw actuator coupled to one of the links which lifts the remaining links by rotation about its pivotal attachment to the chair frame, and similarly uses another lead-screw actuator coupled to the next link. The actuation mechanism can be operated by an on-board motion control computer for controlling the trajectory and velocity of the arm. A docking station integrated with the frame mates with a docking feature on the target object and stabilizes the chair while transferring the user. The transfer chair may be constructed using modular components that allow the unit to be assembled or reconfigured into one of a number of different product designs. Four such modules may include a front module which houses the front pivoted casters or wheels and foot rests, a center module which provides the lifting/transfer/elevate functions, a propulsion module having the rear wheels, variable speed/reversible gear drive motors, batteries, and a chair control computer, and a rear module which contains the seat back cushion and support, and any push handles and controls for operation by an caregiver.
摘要翻译：转椅具有椅架，座椅，轮子和升降臂，其具有在家庭和目标位置之间的铰接路径。提升臂被铰接，使得附接到提升臂的远端的提升带在运动期间相对于椅子框架保持恒定的角度定向。提升臂使用四个连杆构成，四个连杆可以端对端地枢转地连接，并可以折叠到椅子框架内的收起位置。致动机构使用联接到其中一个链节的导螺杆致动器，其中的一个链节通过围绕其枢转附件转动到椅子框架而旋转其余的连杆，并且类似地使用与下一个链节相连接的另一导螺杆致动器。致动机构可以由板上运动控制计算机操作，用于控制臂的轨迹和速度。与框架集成的对接站与目标对象上的对接功能相配合，并在传送用户时稳定椅子。转移椅可以使用模块化部件来构造，其允许将该单元组装或重新配置成多种不同的产品设计之一。四个这样的模块可以包括前部模块，其容纳前部枢转的脚轮或车轮和脚踏板，提供提升/传递/提升功能的中心模块，具有后轮的推进模块，可变速/可逆齿轮驱动电动机，电池以及椅子控制计算机，以及包含座椅靠背垫和支撑件的后部模块，以及由护理者操作的任何推动手柄和控制装置。
