Definitions
- the present invention relates to a door system for an elevator car.
- the invention relates to an elevator system which includes at least one elevator car equipped with such a door system, and to a method for evacuating an elevator car equipped with such a door system.
- US 9,284,159 B2 shows an example of a separate side emergency opening that can be closed via a pivoting door.
- a first aspect of the invention relates to a door system for an elevator car, which can be moved between several floors in an elevator shaft and at least has a cabin opening.
- the door system comprises at least one door leaf for closing at least a partial area of the car opening and a storage device which is designed to move the door leaf on the elevator car in the direction of a displacement axis between an opening position in which the door leaf exposes the partial area and a closed position in which the Door leaf closes the partial area, to be displaceable and additionally rotatable about an axis of rotation, so that the door leaf, when it is moved into the closed position and / or into an intermediate position between the opening and the closing position, can be rotated into an emergency opening position in which the The car opening is released to such an extent that the elevator car can be evacuated via the car opening.
- the carrier passing through the elevator shaft has stopped.
- This can be, for example, a retaining clip for the guide rail.
- a second aspect of the invention relates to an elevator system.
- the elevator system includes an elevator shaft and at least one elevator car, which can be moved between several floors in the elevator shaft and has at least one car opening.
- the elevator car includes at least one door system, as described above and below, wherein the door leaf is mounted via the storage device on the elevator car in the direction of the displacement axis between the opening and the closing position and is additionally rotatable about the axis of rotation.
- the car opening can be a main opening of the elevator car, via which passengers can enter the elevator car from a floor and/or leave it to a floor during normal operation of the elevator system.
- the car opening can, for example, be opposite a door opening in a side wall of the elevator shaft if the elevator car regularly stops on a floor.
- the elevator car can also have a plurality of car openings, for example opposite one another, whereby each car opening can be combined with a door system, as described above and below.
- the axis of rotation can, for example, be orthogonal to the displacement axis.
- the axis of rotation can be a vertical axis in the operational state of the elevator car.
- the axis of rotation can, for example, be displaceable together with the door leaf in the direction of the displacement axis (see also below).
- the axis of rotation can intersect the displacement axis or be offset laterally, for example horizontally, from the displacement axis.
- the alignment of the axis of rotation relative to the displacement axis can be constant when the door leaf is displaced between the opening and closing positions. However, it is also conceivable to change the lateral offset of the axis of rotation to the axis of displacement depending on the displacement path of the door leaf.
- the folding and/or the sliding part can be made in one or more parts, for example in the form of an elongated profile or a strip.
- the sliding part can, for example, be designed as a guide shoe for guidance in a corresponding guide rail, which can be arranged above and/or below the cabin opening.
- the folding part can be locked to the sliding part via at least one locking bolt, the locking bolt in the locked state partially engaging in the folding part and partially in the sliding part and in the unlocked state not engaging in the folding part, not in the sliding part or neither in the folding part nor in the sliding part.
- the locking bolt can engage in a corresponding locking receptacle on the folding and/or sliding part, for example in the form of a locking opening. Accordingly, the folding part can be unlocked by moving the locking bolt out of the locking receptacle. Locking and/or unlocking can be done manually and/or automatically.
- the locking bolt can engage in a second end of the folding part in the locked state.
- the folding part can, for example, extend over the entire or a large part of the width of the door leaf, whereby “width” can be understood as an extension of the door leaf in the horizontal direction when the elevator car is in an operational state.
- the storage and locking bolts - viewed in the horizontal direction or in the direction of the width of the door leaf - can be arranged at opposite ends of the door leaf.
- the locking bolt can therefore only be moved from the locking to the unlocking position by overcoming the restoring force. This prevents the folding part from being unlocked unintentionally, for example due to mechanical shocks.
- the restoring force also causes the locking bolt to move back into the locking position when released, which simplifies locking.
- the locking bolt can be connectable to an elongated traction means and can be displaced or displaced from the locking to the unlocking position by pulling on the traction means connected to the locking bolt.
- the traction means can be a flexible, sufficiently tensile means such as a rope or wire.
- the traction means can be accessible from inside and/or outside the elevator car.
- the traction means can be suitably protected against unauthorized access during normal operation of the elevator system.
- Such a locking or actuation mechanism is particularly low-maintenance and takes up little space.
- the storage device can further comprise a further folding part and a further sliding part.
- the further sliding part can be slidably storable on the elevator car in the direction of the displacement axis between the opening and closing positions, wherein the further folding part can be rotatable about the axis of rotation on the further sliding part, so that the further folding part can be displaced together with the further sliding part.
- the door leaf can be fastened at its first end to the folding part and at its second end to the further folding part, so that the door leaf can be rotated together with the folding part and the further folding part.
- the sliding part as an upper sliding part, can close an upper edge region of the door opening in the emergency opening position, and / or the further sliding part can, as a lower sliding part, close a lower edge region of the door opening in the emergency opening position.
- the door system can further comprise at least one further door leaf for closing a further partial area of the cabin opening.
- the storage device can also be designed to displace the further door leaf on the elevator car in the direction of the displacement axis between an opening position in which the further door leaf exposes the further partial area and a closed position in which the further door leaf closes the further partial area and/or or to rotatably mount another axis of rotation parallel to the axis of rotation.
- the door leaves can be, for example, a left and a right door leaf, whereby the car opening can be closed when the elevator car is in an operational state by moving the door leaves towards one another in opposite directions, or can be released by moving the door leaves in opposite directions be moved away from each other. It is also possible for both door leaves to be displaceable in the same direction from the same side of the cabin opening and/or towards the same side of the cabin opening. This embodiment makes it possible, for example, for more than one door leaf to be turned into the emergency opening position. This reduces the risk that the cabin opening cannot be opened wide enough in the event of an evacuation.
- the door leaves can, for example, be rotatable independently of one another about their axes of rotation.
- the door leaf can first be unlocked by unlocking the folding part and then rotated into the emergency opening position.
- the fact that the door leaf must first be unlocked prevents the door leaf from being accidentally opened during normal operation of the elevator system.
- the door leaf can be pivoted into the elevator car when turning into the emergency opening position. This means that the door leaf can largely protrude into the elevator car in the emergency opening position. This can be an advantage in narrow elevator shafts. Additionally or alternatively, the door leaf can be expanded by one vertical axis can be rotated as the axis of rotation. Accordingly, the door leaf or the door leaves can be mounted so as to be displaceable in the direction of a horizontal axis as the displacement axis.
- only one individual door leaf can be turned into the emergency opening position.
- only the front door leaf can preferably be rotated into the emergency opening position. This is quite enough to evacuate passengers from the cabin.
