Abstract (en)
[origin: EP2752136A1] [Problem to be solved] In the conventional motor-driven bed, the degree of freedom of design including the location where the crank handle is installed is low, and the object of the present invention is to increase the degree of freedom. [Solution] The present invention is a motor-driven bed, in which the bed bottom is vertically moved and pivotally moved by using an actuator (9) having a rotation-linear motion converting mechanism, characterized in that the rotation side of the rotation-linear motion converting mechanism of the actuator comprises a DC motor and a speed reducing mechanism, and that the power is supplied to the DC motor selectively by either a controller (18) connected with the commercial power supply or a manual power generator (1) driven by a crank handle (7). The manual power generator is configured to ensure that a DC motor capable of acting reversely and a speed increasing mechanism are respectively housed in a device body (5), and that a crank handle connected with the input shaft of the speed increasing mechanism and a power supply cable (8) are provided outside the device body, and the speed increasing mechanism is configured as a worm gear mechanism provided with a worm wheel on the crank handle side and a worm as a multiple-threaded screw on the DC motor side, in order to greatly decrease the size and weight.
