The invention relates to a device for hospital beds or the like which have a bottom frame adjustable to different positions in relation to a main frame, said device being designed to indicate when the bottom frame has reached its horizontal position. The device comprises means which are arranged on two elements which are movable relative to each other during pivoting of the bottom frame. When said elements reach their relative position corresponding to the horizontal position, and there has been a sudden change in the force or resistance needed for the relative displacement, said means indicate that the horizontal position has been reached. <IMAGE> |
