Abstract
A door seal for an elevator car includes a first tube and a second tube made of an elastically deformable sealing material; the door seal adapted to be mounted on a car wall and/or car door of the elevator car such that the first and second tubes, when the door closes a door opening in the car wall, lie opposite one another within a door gap in a bridging direction and run at least partially around the door opening. The first tube has a pressure connection and can be deformed, by applying fluid pressure, between an initial shape and a final shape that is enlarged in the bridging direction compared to the initial shape. The second tube has at least one pressure equalization opening that enables pressure equalization between an interior and an environment of the second tube when the second tube is compressed.
Claims17
A door seal for an elevator car, the elevator car having a car wall with a door opening formed therein and a door for closing the door opening, wherein when the door closes the door opening the door is separated from the car wall by a door gap, the door seal comprising:
- a first tube made of an elastically deformable sealing material forming an enclosed profile;
- wherein the first tube has a pressure connection for applying a fluid pressure to an interior of the first tube to deform the first tube by changing the fluid pressure, the first tube being deformable between an initial shape and a final shape enlarged in a bridging direction compared to the initial shape, the bridging direction extending horizontally across the door gap;
- a second tube made of an elastically deformable sealing material forming an enclosed profile separate from the enclosed profile of the first tube;
- wherein the door seal is adapted to be mounted on the car wall and/or on the door such that, when the door closes the door opening, the first tube lies opposite the second tube within the door gap in the bridging direction and the first tube and the second tube run at least partially around the door opening;
- and
- wherein the second tube has at least one pressure equalization opening formed therein enabling pressure equalization between an interior of the second tube and an environment of the second tube when the second tube is compressed.
A door seal for an elevator car, the elevator car having a car wall with a door opening formed therein and a door for closing the door opening, wherein when the door closes the door opening the door is separated from the car wall by a door gap, the door seal comprising:
- a first tube made of an elastically deformable sealing material;
- wherein the first tube has a pressure connection for applying a fluid pressure to an interior of the first tube to deform the first tube by changing the fluid pressure, the first tube being deformable between an initial shape and a final shape enlarged in a bridging direction compared to the initial shape, the bridging direction extending horizontally across the door gap;
- a second tube made of an elastically deformable sealing material;
- wherein the door seal is adapted to be mounted on the car wall and/or on the door such that, when the door closes the door opening, the first tube lies opposite the second tube within the door gap in the bridging direction and the first tube and the second tube run at least partially around the door opening;
- and
- wherein the second tube has a plurality of pressure equalization openings formed therein enabling pressure equalization between an interior of the second tube and an environment of the second tube when the second tube is compressed, the pressure equalization openings being distributed in a longitudinal direction of the second tube.
A door seal for an elevator car, the elevator car having a car wall with a door opening formed therein and a door for closing the door opening, wherein when the door closes the door opening the door is separated from the car wall by a door gap, the door seal comprising:
- a first tube made of an elastically deformable sealing material surrounding a first interior;
- wherein the first tube has a pressure connection for applying a fluid pressure to the first interior of the first tube to deform the first tube by changing the fluid pressure, the first tube being deformable between an initial shape and a final shape enlarged in a bridging direction compared to the initial shape, the bridging direction extending horizontally across the door gap;
- a second tube made of an elastically deformable sealing material surrounding a second interior isolated from the first interior preventing fluid communication between the first interior and the second interior;
- wherein the door seal is adapted to be mounted on the car wall and/or on the door such that, when the door closes the door opening, the first tube lies opposite the second tube within the door gap in the bridging direction and the first tube and the second tube run at least partially around the door opening;
- and
- wherein the second tube has at least one pressure equalization opening to an environment of the second tube formed therein enabling pressure equalization between the second interior of the second tube and the environment of the second tube when the second tube is compressed.
