Document Type and Number:
WIPO Patent Application WO/2013/055057
Kind Code:
A3
Abstract:
The present invention relates to an electrical foldable bed. According to an embodiment of the present invention, the electrical foldable bed includes: a support frame; a main frame connected to the support frame so that the main frame is supported at a predetermined height from the ground; a backrest part disposed on an upper portion of the main frame and having one end slidably disposed on the main frame; a center support disposed on the upper portion of the main frame to be varied in length by an external force and having one end rotatably coupled to an end of the backrest; a first driving module contracted in one direction and having one end rotatably coupled to the support frame or the main frame; a rotational member rotatably coupled to the main frame and being rotatably coupled to the other end of the first driving module at a position in which the rotational member is spaced a predetermined distance from a rotational shaft coupled to the main frame; and a first connection module connected to the rotational member, slidably coupled to the backrest, and rotatably coupled to the center support, the first connection module rotating the rotational member when the first driving module is contracted so that an end of the backrest is tilted upward and, simultaneously, the center support is moved in a sliding manner.
