FIELD: personal and household items. ^ SUBSTANCE: ascensional bed contains a frame with a mattress and a mechanism of moving the frame, guiding member and counterweight. Mechanism of movement is made with the capability of reciprocative transportation and contains flexible connections, connecting the frame with the counterweight. Guiding members interact with the flexible connections. Flexible connections joined in one closed flexible connection, containing three pairs of vertical parts, located on the path of motion of the three angles of the frame, and two pairs of horizontal parts, parallel adjacent sides of the frame and placed on one level. Frame is rigidly fixed on the corners with the vertical parts of the flexible connection. Guiding members contain three pairs of cable sheaves with a horizontal axis of rotation, located under three corners of the frame, and one cable sheave with a vertical axis of rotation. Counterweight is rigidly fixed on two adjacent vertical parts of the flexible connection with the capability of movement in the direction opposite to the direction of movement of the frame. ^ EFFECT: increase in free room space after moving the frame to the non-operative position and ease of exploitation. ^ 2 cl, 8 dwg |
