    • A bed structure includes a frame 28, a deck framework 50 moveably connected to the frame, a panel 72 moveably connected to the deck framework, and a motion converter 100. The motion converter translates the panel relative to the deck framework in response to either or both of a) relative translation between the deck framework and the frame, and b) relative rotation of the deck framework and the frame. In one detailed embodiment the motion converter includes a rack 102 secured to the frame, a primary gear 124 meshing with the rack, a panel drive sprocket 170 rotatably mounted on the deck framework coaxially with the primary gear, an idler sprocket 192 rotatably mounted on the deck framework remote from the panel drive sprocket, a slider connected to the panel, and a chain 220 engaged with the panel drive sprocket and the idler and connected to the slider.
    • 床结构包括框架28,可移动地连接到框架的甲板框架50,可移动地连接到甲板框架的面板72和运动转换器100.运动转换器响应于任何一个或多个运动转换器 a)甲板框架和框架之间的相对平移,以及b)甲板框架和框架的相对旋转。 在一个详细的实施例中,运动转换器包括固定到框架的齿条102,与齿条啮合的主齿轮124,与主齿轮同轴地可旋转地安装在甲板架上的面板驱动链轮170,可旋转地安装在 远离面板驱动链轮的平台框架,连接到面板的滑块和与面板驱动链轮和惰轮接合并连接到滑块的链220。
