Abstract:
An elevator car has an access opening, a car door for closing the access opening, which door has at least one door panel that can be displaced parallel to the access opening, a thrust crank drive for displacing the at least one door panel between an open position and a closed position, an electric motor for driving the thrust crank drive, and a control device for actuating the electric motor. The control device actuates the electric motor so that a displacement velocity of the at least one door panel is substantially constant over the entire displacement path between the open position and the closed position of the door panel.
Abstract:
A coupling system of an elevator car door drive includes a traction device, at least one coupling unit coupled to the traction device, and an adapter element which has a first interlocking adjustment structure which, together with interlocking elements of the traction device, forms a first interlocking unit that secures a relative position of the adapter element with respect to the traction device, which relative position can be adjusted in defined interlocking adjustment positions. The coupling unit has a second interlocking unit which secures a relative position of the adapter element with respect to the coupling unit, which relative position can be adjusted in defined interlocking adjustment positions, wherein, in the second interlocking unit, the distance between directly adjacent interlocking adjustment positions is smaller than the distance between directly adjacent interlocking adjustment positions of the first interlocking unit.
Abstract:
A method of modernizing an elevator door system of an elevator installation wherein a door drive together with a car door/shaft door coupling, which is mounted at a car door in a door opening region thereof, and a shaft door lock, which is mounted at a shaft door in a door opening region of the same, are replaced. A new door drive and a new car door/shaft door coupling are arranged at the car, wherein the fastening points of the new coupling are arranged in the region above the door opening and a new shaft door lock is arranged at the original shaft door in correspondence with the arrangement of the new car door/shaft door coupling above the door opening of the shaft door.
Abstract:
A method of modernizing the car door system of a elevator car, which originally comprises at least one car door leaf, a door drive with a crank gear and a drive linkage displacing the car door leaf and a car door/shaft door coupling actuated by the drive linkage, with the following method steps: demounting the door drive together with the crank gear and the drive linkage, mounting a door drive with a linearly moved drive means and coupling of the drive means with the car door leaf of the original car door system, and mounting an actuating device for actuating the car door/shaft door coupling.
Abstract:
An elevator shaft door having a door panel composed of a front wall and rear wall, which walls are connected together by a thermally releasable material, wherein at least a part of the closing edge of the respective door panels consists of a profile member that is formed by the back wall or thermally non-detachably fastened to the back wall. In the case of a fire, the back wall separates from the front wall through release of the thermally releasable material, wherein the front wall curves by heat effect while the back wall with the closing edge retains the original shape.

Abstract:
An elevator installation includes an elevator cage, which is movable in an elevator shaft, with a cage door suspension for a cage door, wherein the cage door suspension is movably arranged at the elevator cage by means of at least one movable mount. During operation of the elevator installation, a self-centering aligning movement of the cage door suspension from a skewed setting of the elevator cage, in correspondence with a skew setting axis, to an approximately vertical and centered setting of the cage door suspension in correspondence with a vertical, can be performed.

Abstract:
An elevator installation has an elevator hoistway with at least one hoistway door. The hoistway door has at least one horizontally movable hoistway-door panel and a door-closing device with an energy store to cause a closing movement of the hoistway-door panel, the energy store being arranged in a space between the opened hoistway-door panel and the hoistway wall on the hoistway-door side.
Abstract:
An elevator car for an elevator system includes a car door, a car door mechanism, at least one car door panel, a door drive motor, and a drive control device for the door drive motor. The car door mechanism thereby supports the car door panel. The drive control device includes an operator module having an operator panel, wherein the operator module is disposed on the elevator car so that the operator panel can be operated from the roof of the elevator car and through an opened shaft door from a building floor.
