Disclosed is a multi-functional bed structure which includes a main operational control unit and a bed portion. The main operational control unit includes an elevating mechanism which can be controlled to cause the bed portion to move up and down or forward and backward reciprocatingly in different selected manners. The bed portion may be a roller type or a non-roller type. A roller type bed portion includes a chassis structure below a mattress-supporting bed frame provided with roller rails. A lifting mechanism is mounted on the chassis structure to lift or lower the bed frame by engaging rollers connected to a top of the lifting mechanism with the roller rails on the bed frame. A raising mechanism is mounted below the bed frame to raise different parts of the mattress as needed by the user. The elevating, the lifting, and the raising mechanisms all can be operated in three different control manners, namely, manual, displacement range, and random controls, so that the bed portion may be shifted rhythmically.

[ What is claimed is:] [1.] A multifunction bed structure comprising:a main operation control unit including a bed head housing, a base, two upstanding side frames, a space defined by said bed head housing, said base, and said side frames, and an elevating mechanism;said elevating mechanism including a controller disposed in said bed head housing, a motor, a gearbox, and a transmission shaft, an electromagnetic brake disposed in said base, two elevating heads separately disposed inside said two upstanding side frames and two driving mechanisms for moving the two elevating heads relative to the two upstanding side frames;said motor being controlled by said controller to operate at different speed, displacement, and reverse pause time; said different speed, displacement, and reverse pause time of said motor being grouped into a plurality of different combinations, such that a user may cause said motor to operate via said controller in a manner selected from one or more groups of said combinations of different motor speed, displacement and reverse pause time; said manner of operation of said motor including an irregular operation in which more than one group of motor speed, displacement and reverse pause time combination is randomly selected to automatically repeat, a regular operation in which one group of motor speed, displacement and reverse pause time combination is selected to automatically repeat, and a manual operation in which said motor operates and stops at any time and in any group of speed, displacement and reverse pause time combination decided through manual control by a user; said transmission shaft being rotated by said motor via said gearbox to thereby drives said two driving mechanisms in said two upstanding side frames to move up and down, so that said two elevating heads connected to said two driving mechanisms are moved up and down in said two upstanding side frames; anda bed portion being connected at a head end to said main operational control unit via said two elevating heads, wherein said bed is a non-roller type,said non-roller type bed portion including a mattress divided into a movable back rest part, a fixed hip rest part, a movable thigh rest part, and a movable leg rest part, a bed frame supporting said mattress, a folding leg frame connected provided below said bed frame near the head end of said bed portion, a fixed leg frame connected to a rear end of said bed portion, and a mattress raising mechanism provided below said mattress and said bed frame to raise or lower a head end of said back rest part so that said back rest part is adjustably inclined at an angle relative to said bed frame, said raising mechanism also permitting a joint between said thigh rest part and said leg rest part to arch; both said folding and said fixed leg frames having casters mounted to a bottom end thereof, said bed portion with said folding leg frame in a folded position being allowed to slide forward or backward while said elevating heads are driven by said motor to move downward or upward,whereby when said elevating heads are driven by said motor to move up and down within a set displacement range, said bed frame and said mattress are brought by said elevating heads to move up and down and to move forward and backward in a regular or irregular manner, and when said raising mechanism and said lifting mechanism are driven by said controller to respectively raise said bed mattress parts and to lift said bed frame in different manners selected by a user, said bed mattress parts may be laid horizontally or inclinedly to meet actual need of the user.
