摘要：
A table assembly for a patient transfer device has upper and lower tables surrounded by belts which counter-rotate as the table assembly moves between a patient and a supporting surface such as a bed. The table assembly includes integrated means for laterally retracting side plates of the upper table while adjusting incident angles of the side plates and vertically separating the upper table from the lower table. Guide slots in end plates fixed to a slide assembly retain positioning posts attached to ends of the side plates. The slots are inclined upwardly toward a centerline of the table assembly at different angles. A crank moves the side plates using a rotating disk attached to a central frame of the upper table and linkage arms with one end pivotally attached to a peripheral region of the disk and another end pivotally attached to one of the positioning posts. In an alternative embodiment the upper table side plates are differentially extended at the ends, and valve control for pneumatic tubing is integrated with retraction of the side plates. During patient delivery only the delivery side plate is raised, to avoid catching linens in the nip formed between upper and lower belts. The slide assembly supporting the table assembly includes a fixed plate, an intermediate plate, and a full-motion plate which extend by means of rack-and-pinion drives. Each plate is symmetrical, and pinions are symmetrically located on opposite sides of the fixed or intermediate plate to allow hyperextension to either the left or right. Improved steerage for the device is provided by two centerline wheels which counter-rotate from a straight position to a turning position and further to a lateral position wherein the wheels are orthogonal to the longitudinal centerline of the device.病患轉送裝置用平台組合具有上及下平台,該上及下平台被皮帶所圍繞,當平台組合移動於一病患與如病床的支撐表面之間時,該皮帶反向旋轉。平台組合包含整合手段,用於側向縮回上平台之側板而調整側板之進入角,且垂直地將上平台從下平台分離。固定到滑動組合的端板中之導槽扣住固定到側板端部的定位柱。導槽以不同角度朝向平台組合之中心線向上傾斜。一曲柄係使用一固定到上平台之中心骨架的轉盤及連桿臂來移動側板,連桿臂之一端樞轉地固定到轉盤
