An elevator of the present invention includes a guide member spaced apart from a structure and formed in a vertical direction with respect to the ground, a first elevating member coupled to the guide member to be moveable in a longitudinal direction of the guide member, a second elevating member coupled to the guide member to be moveable in the longitudinal direction of the guide member, detachably coupled to a lower side of the first elevating member, and lifted and lowered together with the first elevating member, and at least one connecting unit which connects the first elevating member and the second elevating member.

An elevator car roof includes two toe boards for mounting the elevator car roof at a mounting position to uprights of an elevator car. Each of the toe boards has projecting brackets for holding the elevator car roof at the uprights in the mounting position. Each of the uprights includes a slot for receiving one of the projecting brackets when the elevator car roof is held in the mounting position by the uprights. The projecting brackets and the slots can be formed to prevent a wrong orientation of the elevator car roof relative to the uprights.

An anti-falling device for a door of an elevator of the present invention includes: a door hanger; and a first roller and a second roller both provided on the door hanger and arranged to face a lower end surface of the door rail. The first roller is made of a metal is and arranged at a position downwardly away from the lower end surface of the door rail. The second roller is configured to be in elastic contact with the door rail, and is arranged to be held in contact with the lower end surface or arranged at a position closer to the lower end surface than the first roller.

A support member of a braking device includes a body configured to couple to the braking device. The body has a first portion including a first inclined body surface and a second inclined body surface. The first portion is receivable within an opening having a first inclined opening surface and second inclined opening surface. The first inclined body surface is complementary to the first inclined opening surface and the first portion of the body is movable within the opening.

This invention is directed to a self-propelled elevator system having multiple motors or one motor, and methods for synchronizing said multiple motors. This invention is also directed to an elevator brake system to be used in said self-propelled elevator system or other types of elevators to increase their level of safety.

Elevator systems are described. The elevator systems include an elevator car movable along guide rails within an elevator shaft. The elevator car has a car frame with a platform, a ceiling, and car structural members. A distance between the platform and the ceiling is defined as a car height H.sub.C. An overspeed safety system is provided and includes first and second safety brakes and first and second electromechanical actuators positioned within the car structural members within the car height H.sub.C. The safety brakes are operable to engage with the guide rails to stop movement of the elevator car.

An elevator system including an elevator car frame including an interior side, a service panel operably coupled to the interior side of the elevator car frame, the service panel including a panel interior side and a panel exterior side, and configured to operate between an open and closed position, an elevator car operably coupled to the elevator car frame, the elevator car including an interior cavity, wherein the panel exterior side is disposed within the interior cavity when the service panel is in an open position.

An exemplary elevator system includes an elevator car having an integrated cabin and car frame structure including a platform thickness between a floor surface in the cabin and a lowermost surface on a support beam used for supporting the car beneath the floor surface. A sheave assembly is supported beneath the floor surface. The sheave assembly includes a plurality of sheaves and a plurality of subframe beams. The sheaves and subframe beams fit within the platform thickness such that the subframe beams and the sheaves are no lower than the lowermost surface on the support beam. A plurality of isolation members are between the sheave assembly and the elevator car for isolating an interior of the cabin from vibrations associated with movement of the sheaves.

A support unit for the fastening of a diverting roller to a support structure can be used for supporting a car in an elevator installation. The support unit has two yoke beams and a bearing for the diverting roller. The yoke beams are arranged parallel to one another for fastening to the support structure. On the support unit there are at least two restraint devices that are fastened to the yoke beams and which project into the intermediate space between the yoke beams such that, in the event of failure of the bearing, the restraint devices form a stop to prevent the diverting roller from moving in a support direction under the action of the support force. The support unit is stable, is of simple construction and is of space-saving design.

A floor for use with a glass elevator is provided. The floor includes an upper major surface, a lower major surface opposing the upper major surface, a first side edge, a second side edge, the first and second side edges extending from the upper major surface to the lower major surface. The floor includes one or more front edges and one or more rear edges. The one or more front edges and one or more rear edges extend from the upper major surface to the lower major surface. The floor is formed from a unitary, continuous, solid plate material.
