Patent number: 11390491Abstract: A device for unlocking a landing door includes a door leaf that can be moved between an open position and a closed position, a bar arranged on the door leaf to lock the door leaf in the closed position, and an energy accumulator coupled to the door leaf to provide the energy for moving the door leaf into the closed position in the event that the energy supply needed to drive the door leaf fails. The energy accumulator is coupled to the door leaf by an elastic element such that through a displacement of the energy accumulator when the door leaf is in the closed position, the bar is moved to an unlocked position.Type: GrantFiled: December 1, 2017Date of Patent: July 19, 2022Assignee: INVENTIO AGInventor: Jules Christen

Patent number: 5957242Abstract: A machine frame with two side members at its ends comprises support arms, which are pivotably mounted in semi-circular cut-out bearing supports. The bearing supports may be arranged on differently high pedestals, which may result in different inclined positions for the machine frame with respect to a machine room floor. The inclined position may provide for a variable looping angle .beta. at the drive pulley and variable cable spacing between the cage cables and the counterweight cables. Furthermore, the deflecting roller may be mounted in laterally displaceable bearing plates. The deflecting roller may be inserted above or below a pair of side members. The position of the deflecting roller with respect to the side members may also have an effect on the looping angle .beta. and the cable spacing. The combination of these adjustment possibilities enables the substantially universally adaptability of the machine frame to different elevator systems and applications.Type: GrantFiled: September 13, 1996Date of Patent: September 28, 1999Assignee: Inventio AGInventors: Christian Suter, Jules Christen
