Abstract
1,135,717. Apparatus for operation of up- and-over doors. K. HERMANN. 20 March, 1967 [21 March, 1966; 10 Feb., 1967], No. 12979/67. Heading E2M. An apparatus (as illustrated with reference to up-and-over doors) for continuously balancing energies between an energy-consuming device which performs a pivotal lifting movement and in doing so requires a progressively increasing supply of energy, and an energy storage device which comprises a pre-stressed spring (or springs) and which supplies a progressively diminishing amount of energy, the apparatus comprising energy transmission means disposed between the consuming device and the storage device, is characterized in that the energy transmission means comprises a slide 15 having a cam surface 14 disposed at an inclination to the movement direction of the slide and an energy transmission lever 8 which is acted on by the spring 1 and which by one of its ends engages the said’ cam surface in such away that, if the slide is allowed to move in one direction, the spring is progressively relaxed and, if the slide is urged in the other direction, the spring is progressively stressed, the lever ratio of the transmission lever and the disposition of the cam being such that energy requirement by the consuming device and energy supply from the storage device are balanced throughout the entire lifting movement of the consuming device.
