摘要： This invention discloses an electrically driven elevation bed apparatus which moves up and down while keeping its horizontal posture, in order to make effective use of indoor space. The elevation bed of this invention includes improved driving systems and safety devices for the driving systems. The driving systems includes a driving device including a spring to store biasing force on a supporting shaft thereof for the ascending of the bed frame. Also included is the use of steel belts as cord bodies to hand the bed frame to make the driving device compact and to eliminate troubles encountered with wireropes. The third aspect of the present invention also relates to an improvement of the driving systems. This aspect enables the bed frame to be positioned in inclined postures by introducing clutch means in the driving device to raise one side of the bed only. To the elevation bed, various safety devices are provided for movement of the furniture. They are a detecting device to detect the loss of tension or breakage of cord bodies, a disengagement preventing device to secure the engagement of the bed frame and guide rails, a protecting device using a guard net to prevent the user from falling from the bed and cushioning device to improve the starting motion of the bed frame by eliminating shock and by enabling the driving device to be more effective and safer in its operation. The present invention includes systems which can be combined and the various safety devices are available to be adopted correspondingly and combined freely.

摘要： This invention discloses an elevation bed apparatus which moves up and down while keeping its horizontal posture, in order to improve an effective use of an indoor space. The elevation bed of this invention includes an elevation device and a safety device, and the elevation device includes a winding mechanism and a wire driving system of a wire wound on the winding mechanism. A bed main body moves up and down along a guide rail when the wire is wound and rewound. When the elevation bed is of an electric type, the safety device checks the operation or cuts off the power source to stop the elevating motion of the bed main body. This safety device includes all, or the combination, of a safety device consisting of an elevation management mechanism of the elevation bed disposed on the handrail of the bed main body and the upper surface of the peripheral frame of the bed main body, a slack sensor disposed in a winding path of the wire driving system in order to sense the slack of the wire and to cut off the power source, a descension limit sensor disposed on the lower surface of the bed main body and an ascension limit sensor disposed on the surface of the ceiling above the place of disposition of the bed, and an emergency stop safety means. The present invention includes systems which can correspond to the electric and manual elevation beds, respectively, and modified modes of various safety devices, and can be combined freely.
