Patent number: 11548759Abstract: A system and method for determining an elevator car position uses position markers situated in the elevator shaft and each assigned a discrete car position, first and second detection devices on the elevator car detecting first and second position markers respectively, and an evaluation unit that determines first and second discrete car positions based on the detected first and second position markers respectively. A single interpolation device of the position determining system determines first and second interpolated car positions. The evaluation unit determines first and second car positions based on the first and second discrete car positions and the first and second interpolated car positions respectively. The interpolation device generates an interpolation parameter that characterizes a position of the first detection device relative to the first position marker and determines the first and second interpolated car positions on the basis of the interpolation parameter.Type: GrantFiled: June 26, 2018Date of Patent: January 10, 2023Assignee: INVENTIO AGInventors: David Michel, Eric Birrer, Martin Pfister

Patent number: 9688515Abstract: An elevator car door interlock including a locking assembly, cable assembly, switch assembly, and top mounting assembly. The elevator car door interlock works in combination with flags installed in an elevator's hoistway. A flag is installed in the areas where it is permitted to open the elevator doors. The locking assembly includes an arm that engages the flag. The flag then prevents the arm from reaching its maximum tilt and keeps it in the substantially vertical position. This causes the hook in the locking assembly to remain in the lowered position. The hook in this position allows the cable to freely travel when the elevator doors are attempted to be open. If the elevator is in a locking zone, then there is no flag present and as the door is attempted to be open, a weighted member attached to the bottom of the cable will begin to rise.Type: GrantFiled: June 11, 2014Date of Patent: June 27, 2017Inventors: Ricardo Macareño, Nelson Alonso
