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
