Claims20
An elevator door subsystem comprising:
- a hanger mount having a first side, a second side, and an opening between the first side and second side, the first side having at least a portion configured for arrangement in an opening of an elevator door hanger, and the second side having at least a bearing surface;
- a leveling cam configured for sliding contact with the bearing surface and having a first surface, a second surface, an opening between the first surface and the second surface, and a third surface for contacting the bearing surface;
- an engaging member configured for placement in the opening of the hanger mount and the opening of the leveling cam;
- and
- a roller assembly for receiving the engaging member, such that when the roller assembly is positioned on one side of the elevator door hanger, the hanger mount is positioned within the opening of the elevator door hanger, and the leveling cam is positioned on another side of the elevator door hanger, the engaging member is receivable by the roller assembly after the engaging member is passed through the opening in the leveling cam, the opening in the hanger mount, and the opening in the door hanger.
A method for replacing parts of an elevator door assembly comprising:
- removing rollers from an elevator door hanger of the door assembly;
- installing a hanger mount in an opening of the elevator door hanger, the hanger mount having a first side, a second side, and an opening between the first side and second side, the first side having at least a portion configured for arrangement in the opening of the elevator door hanger, and the second side having at least a bearing surface;
- positioning a roller assembly on one side of the elevator door hanger, the roller assembly being configured to receive an engaging member;
- positioning a leveling cam on another side of the elevator door hanger, the leveling cam configured for sliding contact with the bearing surface and having a first surface, a second surface, an opening between the first surface and the second surface, and a third surface for contacting the bearing surface;
- and
- inserting the engaging member through opening of the hanger mount and the opening of the leveling cam, and securing the engaging member within the roller assembly.
A kit for replacing parts of an elevator door assembly comprising:
- a hanger mount having a first side, a second side, and an opening between the first side and second side, the first side having at least a portion configured for arrangement in an opening of an elevator door hanger, and the second side having at least a bearing surface;
- a leveling cam configured for sliding contact with the bearing surface and having a first surface, a second surface, an opening between the first surface and the second surface, and a third surface for contacting the bearing surface;
- an engaging member configured for placement in the opening of the hanger mount and the opening of the leveling cam;
- and
- a roller assembly for receiving the engaging member, such that when the roller assembly is positioned on one side of the elevator door hanger, the hanger mount is positioned within the opening of the elevator door hanger, and the leveling cam is positioned on another side of the elevator door hanger, the engaging member is receivable by the roller assembly after the engaging member is passed through the opening in the leveling cam, the opening in the hanger mount, and the opening in the door hanger.
