A turntable for vertical support of substantially horizontal loaded surfaces, which has an upper and a lower half, between that it includes a vertical rotatable guiding element. A braking element (6) is located within the guiding element (3), which limits the vertical downward movement of the horizontal surface to a given speed, and the guiding element (3) includes a threaded part (4) that changes the vertical downward movement to rotating motion. The upper half (1) during its downward movement is connected to the lower half (2) by a mechanical coupling for rotation transfer by engagement into the threaded part (4). The braking element (6) is allowing backward movement of the upper half (1) relatively to the lower half (2) substantially without braking after expiry of the loading. The upper half (2) during its upward movement is connected to the lower half (2) without mechanical coupling for rotation transfer.
A turntable for vertical support of substantially horizontal loaded surfaces, which has an upper and a lower half, between that it includes a vertically directed rotatable guiding element characterised in that within the guiding element a braking element is located, which limits the vertical downward movement of the horizontal surface to a given speed, and the guiding element includes a threaded part that changes the vertical downward movement to rotating motion, where the upper half during its downward movement is connected to the lower half by a mechanical coupling for rotation transfer by engagement into the threaded part, and the braking element after expiry of the loaded condition is allowing backward movement of the upper half relatively to the lower half substantially without braking, and where the upper half during its upward movement is connected to the lower half without mechanical coupling for rotation transfer.
