Title:
ELECTRIC BED
Document Type and Number:
WIPO Patent Application WO/2013/051332
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to increase freedom of design because conventional electric beds had little freedom of design including the installation position of the crank handle. [Solution] In this bed which uses an actuator (9) having a rotational motion-to-linear motion conversion mechanism to raise a floor section and perform an undulating action, the rotating side of the rotational motion-to-linear motion conversion mechanism of the actuator is configured by a DC motor and a deceleration mechanism, and the bed has a configuration whereby power to the DC motor is selectively supplied by a controller (18) connected to a commercial power supply and a manual generator (1) driven by a crank handle (7). The manual generator houses the DC motor capable of reverse operation and an acceleration mechanism in a container (5), and has a configuration whereby a power supply cable (8) and the crank handle connected to the input shaft of the acceleration mechanism are provided on the outside of the container. The acceleration mechanism has greatly reduced size and weight, as a result of being configured from a worm gear mechanism using the crank handle side as a worm wheel and the DC motor side as a multiple-thread screw worm.
