Definitions
- the present invention relates to a door system, an elevator with the door system and a method for operating the elevator.
- a car In an elevator, a car is typically moved vertically in a shaft between different floors or levels within a building. On the floors, passengers can enter and exit the car, or other loads to be transported can be loaded into or unloaded from the car.
- shaft doors are arranged on the floor and the car has a car door.
- the car door comprises at least one car door leaf and the shaft door comprises at least one shaft door leaf.
- the car door and the shaft door together form an openable and closable passage from the car to the floor or vice versa.
- the car door has a car door lock that locks one or more car door leaves during travel.
- the shaft door also has a shaft door lock that keeps one or more shaft door leaves locked at least when the car is not present.
- the car door also has a drive that is designed to open and close the car door leaves. Typically, this movement of the car door leaves is transferred to the shaft door leaves to be opened on the floor being approached by means of a door coupling. For this purpose, a first part of the door coupling on the car door works together with a second part of the door coupling on the shaft door.
- the US5485896A shows a simple embodiment of a door clutch. However, this embodiment requires a separate drive for the door coupling. This makes this solution complex to produce.
- a door system solves the problem.
- the door system has at least one shaft door, a car door, a car door drive and a door coupling for coupling the car door to the shaft door.
- the car door and the shaft door can be moved between an open position and a closed position.
- the car door has an electrically activated car door lock, by means of which the car door can be locked and unlocked in the closed position.
- the shaft door has a separate electrically activated shaft door lock, by means of which the shaft door can be locked and unlocked in the closed position.
- the car door drive comprises a motor and a propellant. The car door can be moved from the closed position to an open position and back by means of the propellant.
- the door coupling has a first part, which is arranged on the car door, and has a second part, which is arranged on the shaft door.
- the second part of the door coupling has at least a first vertically aligned guide web protruding from the shaft door and a second vertically aligned guide web protruding from the shaft door.
- the first and second guide webs are arranged at a guide web distance from each other.
- the first part of the door coupling has a contact body, wherein the contact body has a length dimension along a length direction that is greater than the guide web distance.
- the contact body has a width dimension along a width direction that is smaller than the guide web distance.
- the contact body is arranged rotatably on the car door between the first guide web and the second guide web.
- a lever is connected to the drive means and the lever is connected to the contact body in a rotationally fixed manner, so that the contact body can be rotated by means of a movement of the drive means from a decoupled position in which the contact body is arranged with play between the first and second guide webs due to the width dimension, into a coupling position in which the contact body touches the first and second guide webs.
- an elevator solves the problem.
- the elevator comprises a door system according to the first aspect of the invention, a device for position measurement, a cabin and a control device.
- the device for position measurement detects a position of the cabin.
- the control device evaluates the position and controls the opening and closing of the door system.
- a method for operating an elevator according to the second aspect of the invention solves the problem.
- the method includes the steps:
- the car door and the shaft door can work together to allow access from any floor of the elevator into the car.
- the shaft door also closes the shaft when necessary and can thus prevent people from falling into the shaft.
- the car door also closes the car when necessary and can thus prevent people in the car from touching the passing surfaces of the shaft during the ride.
- the cabin door and the shaft door can be designed in different ways.
- the car door and the shaft door can include, for example, a roller door, a folding door, a car door leaf or a shaft door leaf. These configurations can be opened in particular vertically or horizontally.
- the cabin door and the shaft door are preferably movable together between the open position and the closed position.
- the cabin opens the doors normally on one floor, they open together.
- the door system has the advantage that the door system can be manufactured very cost-effectively.
- the door coupling is used exclusively to connect the door Movement of the shaft door to the cabin door. As a result, it can be designed to be very simple since, for example, it does not mechanically activate a locking mechanism.
- a car is preferably moved vertically along the travel path.
- the car door is opened by the car door drive using the propellant.
- the fact that the car is at the height of a floor and optionally that the car has essentially stopped can be determined by the position measuring device.
- the position measuring device determines the position and optionally the speed of the car along the travel path.
- the position measuring device passes position measurement data on to a control unit of the elevator.
- the control unit can be at least partially built into the position measuring device.
- the control unit can control the door drive and thus the opening and closing of the car door and the shaft door.
- the control unit can take into account the position measured by the position measuring device.
- the length direction is the straight connection between two points of the contact body, which have a maximum distance from one another, preferably in a projection onto the plane of the shaft door or the cabin door.
- the width direction is parallel to the distance between two planes between which the contact body rests, so that the contact body is touched by both planes.
- the two planes are also perpendicular to the car door or the shaft door and aligned vertically, i.e. perpendicular to the direction of the door movement, especially when the contact body is in the decoupled position.
- the contact body touches the first and second guide bars in the coupling position because the longitudinal dimension along the length direction is longer than the guide bar distance between the first guide bar and the second guide bar. Therefore, the contact body contacts the first and second guide webs when the contact body rotates.
- the first part of the door coupling is arranged on the cabin door.
- the first part of the door coupling has the contact body.
- the length direction of the contact body is sufficient during travel along the direction of travel, i.e. vertically.
- the width direction is preferably perpendicular to the longitudinal direction and is therefore aligned horizontally in this orientation.
- the contact body is spaced so far from the car door, and the first and second guide webs protrude so far from the shaft door, that the contact body is, at least partially, attached between the first guide web and the second guide web.
- the contact body is spaced from the shaft door, and the guide webs are spaced from the car door.
- the contact body can pass through the second part of the door coupling, in particular the first guide bar and the second guide bar, without contact.
- the contact body is preferably arranged centrally between the first guide bar and the second guide bar. This means that neither noise nor impacts are generated during the cabin's travel when the first part of the door coupling passes through a second part of the door coupling, which is preferably attached to each shaft door.
- the first guide web is arranged parallel to the second guide web.
- the contact body is made from an elastomer.
- Elastomer can be understood to mean, in particular, vulcanizates of natural or synthetic rubber. This has the primary advantage that coupling occurs very quietly.
- the first step of opening the car door involves coupling the car door and the landing door.
- the contact body is rotated by an angle of rotation.
- the length direction of the contact body is twisted and the contact body touches the first and second guide webs with one contact point.
- This rotation is caused by the lever, which is connected to the contact body in a rotation-proof manner.
- the contact body and the lever are designed as a unit and are in particular rotatably mounted on a surface of the cabin door. Storage can, for example, be done via a Bearing pin can be realized, which is attached to the cabin door directly or to a base attached to the cabin door.
- One end of the lever is connected to the contact body, and the other end of the lever is preferably connected in an articulated manner to the propellant of the cabin door drive.
- the door drive motor shifts the propellant a first distance.
- the propellant is displaced so far that the lever is rotated by the coupling angle, and thus the contact body is also rotated by the coupling angle. Since the contact body is firmly connected to the lever, the contact body and the lever each rotate through the same common coupling angle.
- the lever preferably extends at a lead angle from the vertical. If the contact body is coupled, the lever preferably extends substantially vertically.
- the car door and the shaft door are coupled as soon as the contact body touches the first guide bar and the second guide bar.
- the propellant is characterized in that at least parts of the propellant move linearly along the door opening direction, and that by means of the indirect coupling of the propellant via the contact body and the lever to the cabin door, the cabin door is moved by the propellant.
- the propellant can be designed, for example, as a spindle drive, rack drive, scissor linkage, hydraulic cylinder or pneumatic cylinder.
- the drive means is designed as a drive means rotating around a first roller and a second roller, and preferably the first roller is driven by the door drive.
- the first roller is preferably arranged on the door drive.
- the second role is arranged opposite the first role on the door fighter.
- the propellant that runs over the roller can be a chain, a rope, a belt or a toothed belt.
- the length direction of the contact body is rotated from the vertical direction by a coupling angle between 10° and 80° in the coupled state. More preferably, the coupling angle is between 15° and 40°. Even more preferably, the coupling angle is 30°. This has the advantage that the first distance that the propellant travels for coupling is short.
- the contact body touches the first guide web at a first contact point and the second guide web at a second contact point.
- the two contact points prevent the contact body from twisting further. This results in the advantageous effect that when the door is subsequently opened, a force applied by a door closing device increases or at least maintains a contact force at the contact points, between the contact body and the guide webs.
- a force applied by a door closing device increases or at least maintains a contact force at the contact points, between the contact body and the guide webs.
- the coupling angle can be the same as the lead angle.
- the lever is essentially vertical in the coupled position.
- the coupling angle can be between 70° and 110° or preferably 90°.
- the contact body or the lever has a stop that prevents further rotation after the coupling angle is reached.
- the lead angle is preferably 45°. This causes the lever to move 90° between the coupled position, which deviates by 45° from a vertical direction, and the uncoupled position, which also deviates by 45° from a vertical direction.
- the coupled and uncoupled positions are therefore symmetrical to one another with respect to the vertical direction.
- the high friction of the elastomers keeps the contact body in the position rotated by 90°.
- the elastomers generate high friction forces because the contact body is clamped between the first guide web and the second guide web.
- the length dimension is only slightly, preferably between one per mille and 5% larger than the guide bar spacing.
- the shaft door lock can be opened. It is now advantageous that the car door lock and the shaft door lock can be activated electrically.
- the power to unlock the electrically activated cabin door lock can be provided directly in the cabin by a control unit.
- a control unit on the floor or in the machine room can provide the power to activate the shaft door lock.
- Both locks preferably have a monitoring device which monitors the position of the locks.
- the shaft door lock and the car door lock can be constructed in essentially the same way.
- the electrical activation of the locks is based on the principle that a control device generates signals that cause the shaft door lock or the car door lock to open or close.
- the unlocking preferably takes place directly via the power supply of a lifting magnet, which means that a lifting magnet is preferably energized by the control device, which then opens the lock.
- the power can be generated directly in or on the control device.
- the control device can send a command to an activation component via a bus system, whereupon the activation component switches on the power, which then activates the lifting magnet.
- the signal line to the shaft door lock and the signal line to the car door lock can be connected directly via a cable.
- a bus system can be used, which then sends additional status data from the shaft door lock or the car door lock back to the elevator control unit.
- Status data includes, for example, the state of the car door lock or the shaft door lock, data on the duration of the door movements or the power consumption of the drive.
- the lifting magnet is supplied with electricity, so that the lock opens when a bolt is removed from engagement with a bolt stop.
- the bolt falls back into engagement with the bolt stop, for example by a spring or a weight pre-tensioning the bolt towards the position in engagement with the bolt stop.
- the bolt can be designed in such a way that the lock can be locked when the power supply is switched off by the bolt being able to be moved over the bolt stop using a one-sided chamfer. It can therefore function like a snap lock.
- the door operator can move the propellant a second distance toward the opening direction.
- the door drive moves the car door together with the shaft door into the open position.
- the activation of the car door locking and the landing door locking can be ended. This can save energy.
- the method further comprises the step of closing the car door and the shaft door.
- the car door lock and the shaft door lock can preferably remain deactivated if the respective latches are bevelled.
- the method further comprises the steps:
- the door drive moves the propellant a third distance and closes the doors with this movement.
- the movement is preferably controlled in such a way that When the closed position is reached, the speed of movement is very low or the door drive preferably stops briefly. This prevents the doors from hitting each other and the doors close quietly.
- the locking can remain deactivated when closing.
- the cabin lock and the shaft lock can, for example, have a snap mechanism, as is preferably implemented by a chamfered bolt.
- the cabin lock and the shaft lock are preferably activated when closing in order to reduce the noise when locking and to prevent snapping noises, for example.
- the snap mechanism could otherwise cause a snap noise when passing the locking stop, for example.
- the propellant is moved a fourth distance by the door drive and the cabin door is decoupled from the shaft door. The cabin can now be moved safely along the travel path again.
- the bolt stop can be designed as a nose of the cabin door or as a recess in the cabin door.
- the bolt is preferably pretensioned by a spring in such a way that the bolt potentially engages with the bolt stop when the car door lock or shaft door lock is not activated.
- the car door has at least a first car door leaf and the shaft door has at least a first shaft door leaf.
- the first car door leaf and/or the first shaft door leaf are a fixed door leaf.
- a door leaf is flat and rectangular and is displaceable transversely to the direction of passage through the door.
- the first and second guide webs can be attached to the shaft door leaf.
- the storage or the base used to support the contact body can be arranged on the cabin door leaf.
- the car door has a second car door leaf
- the shaft door has a second shaft door leaf
- a first door coupling couples the first car door leaf to the first shaft door leaf
- a second door coupling couples the second car door leaf to the second shaft door leaf.
- the first car door leaf and the second car door leaf can be moved telescopically.
- the first car door leaf moves faster, in particular twice as fast, as the second car door leaf. It is advantageous here that the door coupling and the car door lock are attached to the first door leaf, which moves faster.
- the coupled first shaft door leaf preferably moves twice as fast as the second shaft door leaf.
- the movement of the second shaft door leaf is brought about by a mechanism that transfers the movement of the first shaft door leaf to the second shaft door leaf, reduced by 50%.
- a second door coupling can couple the second car door leaf to the second landing door leaf.
- This is particularly advantageous for centrally opening doors. With centrally opening doors, the door leaves open away from each other in opposite directions. This means that the two shaft doors do not have to be coupled to one another, but can be moved independently of one another. This saves additional mechanics for each shaft door, such as circumferential ropes, which would cause this coupling.
- the car has a second door coupling for a second car door leaf and a second shaft door leaf.
- the use of the two shaft door leaves is preferably analogous to the use of the two car door leaves.
- the contact body, the first guide web and the second guide web are arranged above the car door and/or above the shaft door.
- the door coupling is above an infinitely extended horizontal plane, which rests tangentially on an upper end of the shaft door and / or the cabin door and in particular an upper end of the first shaft door leaf and / or the first cabin door leaf. Since the door coupling is arranged above the car door panel or the shaft door panel, at least parts of the door coupling can be arranged vertically above the door and less space is required between the car door and the shaft door. As a result, the shaft door panel and the car door panel can be arranged very close to one another because, for example, the lever or a support structure for the guide webs can be arranged outside the gap that lies between the car door and the shaft door. The shaft door and the cabin door are therefore arranged very close to one another and there is therefore more space left to make the interior of the cabin larger.
- the door system has a prestressing device which applies a prestressing force to the contact body in the direction of the decoupled orientation.
- the preload force can be designed in such a way that, for example, a torsion spring is connected to the contact body, the unstressed position of which is aligned so that the contact body is aligned along the direction of travel.
- a tension spring can be connected to the contact body in such a way that the shortest length is achieved when the contact body is aligned along the direction of travel.
- Another alternative embodiment consists in arranging a stop between the cabin door and the contact body. The lever is preloaded by a spring so that it is pressed against the stop. If the lever rests against the stop, the contact body is aligned along the direction of travel.
- the pre-tensioning device is designed as an elastomer torsion spring.
- elastomer torsion springs are sold, for example, by the company Rosta as Rosta elements. They act simultaneously as a bearing element and as a return spring.
- the first guide web and the second guide web have a common guide web base.
- the common guide web base can be a separate element such as a guide web support.
- the guide web support determines the guide spacing. It preferably also has holes and/or threads to attach the guide webs to the guide web support and the guide web support to the shaft door.
- the common guide web base can be designed in that the first guide web, the common guide web base and the second guide web together form a body. Preferably, they form a U-profile, wherein the common guide web base comprises the middle part of the U-profile.
- the U-profile can be constructed in such a way that the guide distance is fixed and therefore in particular cannot be changed.
- the guide web base can be used to attach the U-profile to the shaft door, for example with screws.
- the guide web base can also have anchor holes that allow the U-profile to be easily arranged and aligned in the correct position. In other words, so that the contact body is in the middle between the first guide web and the second guide web, and that the guide webs are aligned along the travel path.
- the connector closes the rotating propellant to form a closed circle and allows the length of the propellant to be adjusted to the distance between the rollers.
- the connector preferably has a pin or a hole, which can be used to achieve an articulated connection to the lever.
- Door closing device on the shaft door, whereby the force of the door closing device is greater than the tensile force that the propellant causes on the lever to move the contact body into the coupling position.
- Door closing weights or door closing springs can be used as door closing devices.
- Fig. 1 a cabin door 21,
- Fig. 2 a shaft door 22 matching the car door 21, Fig. 3 a horizontal section through the door coupling Fig. 4 a view of the door coupling in coupled position Fig. 5 a view of the door coupling in coupled position Fig. 6 an elevator 100
- the propellant 14 is guided over the two rollers 5, which are arranged at essentially opposite ends of the door fighter 2a.
- a connector 15 connects the ends of the propellant 14 to one another and also establishes a connection between the propellant 14 and the lever 18.
- the lever 18 is connected to the contact body 13 in a rotationally fixed manner. So they form a unit.
- the unit consisting of lever 18 and contact body 13 is mounted on a bearing 51 which is located on base 17.
- the base 17 is designed in such a way that the base 17 and the lever 18 rest essentially vertically above and above the first cabin door leaf 21a. So that essentially only the contact body 13 protrudes beyond a projection of the first car door leaf 21a in order to be able to couple with the opposite first shaft door or the first and second guide webs attached to it.
- the first cabin door leaf 21a has a latch stop 34.
- the latch 33 of the car door lock 31 engages in the latch stop 34 when the car door lock 31 is not activated. This makes the cabin door 21 and in particular that first cabin door leaf 21a locked.
- the car door lock 31 is activated by activating the car door lock actuator 32.
- the actuator 32 can have a lifting magnet, which is energized for activation, and the lifting magnet then uses a magnetic force to lift the bolt 33 out of engagement with the bolt stop 34.
- the weight of the bolt or the force of a spring can serve as a counterforce.
- Fig. 2 shows the shaft door 22 which would be arranged together with the car door 21 of Fig. 1 in a door system 1.
- the door system 1 comprises the combination of the car door 21 as shown in Fig. 1 and the matching shaft door 22 as shown in Fig. 2.
- the components of the door system 1 shown in Fig. 2 are essentially reversed to the representation of similar components of the car door 21 in Fig. 1, because the shaft door shows a view from the opposite direction.
- the shaft door 22 also opens telescopically.
- the first shaft door leaf 22a and the second shaft door leaf 22b are guided along the shaft door threshold 3b and the shaft door fighter 2b.
- the shaft door lock 41 is also constructed analogously to the cabin door lock.
- a shaft door latch 43 is in engagement with a shaft latch stop 44 when not activated.
- the actuator 42 of the shaft door lock can be energized in order to lift the latch 43 out of engagement with the latch stop 44.
- a first guide web 11 and a second guide web 12 are attached to the first shaft door leaf 22a.
- the two guide webs 11, 12 are arranged so that the contact body 13 is placed between the first guide web 11 and the second guide web 12.
- the contact body 13 is shown in dashed lines because it is attached to the cabin door 21 and would therefore not actually be visible when looking at the shaft door 22. It is therefore shown where the contact body 13 would be located if the cabin 7 were located on the same floor.
- the guide webs 11, 12 are attached independently of one another to the first shaft door leaf 22a.
- some of the guide webs 11, 12 are attached vertically over the first shaft door leaf 22a. Only so much of the guide webs 11, 12 protrudes beyond the first shaft door leaf 22a that a coupling with the opposite contact body 13 is possible.
- Fig. 3 shows the horizontal section through a non-activated door coupling.
- the contact body 13 is at a distance from the guide webs 11 and 12.
- the cabin can therefore drive past the floor without touching the guide bars 11 or 12.
- the guide webs 11 and 12 show a preferred embodiment.
- the first guide bar 11 is connected to the second guide bar 12 via a guide bar base 50.
- the guide bar base 50 of the two guide bars 11, 12 is attached directly to the front of the shaft door 22.
- the guide bar base 50 would be attached on top of the shaft door 22 and only the guide bars 11 and 12 would protrude into the gap between the shaft door 22 and the car door 21.
- the situation is similar with the bearing 51 of the contact body 13.
- the bearing 51 of the contact body 13 is attached directly to the front of the cabin door 21.
- the bearing 51 would be mounted on top of the cabin door 21 and only the contact body 13 would protrude into the gap between the shaft door 22 and the cabin door 21.
- the contact body has a length dimension L along a length direction and a width dimension B along a width direction.
- the guide webs 11 and 12 are arranged parallel to each other at a guide web distance D.
- the propellant 14 is shifted to the left by the door drive.
- the contact body touches the guide webs 11 and 12 with two contact points 16.
- a first contact point 16 touches the first guide web 11 and a second contact point touches the second guide web 12.
- the contact body 13 is now rotated by a coupling angle ⁇ .
- the coupling angle ⁇ is preferably the same size as the lead angle a.
- the lever in Fig. 5 is oriented vertically.
- the car door lock 31 and the shaft door lock 41 can be unlocked.
- the propellant 14 is moved further to the left.
- the force at the contact point 16 between the contact body 13 and the first guide web 11 increases and the car door 21 and the shaft door 22 open together.
- the cabin door 21 and the shaft door 22 are closed in the reverse order. It is advantageous to select the course of movement of the propellant 14 so that the propellant stops briefly at the position shown in FIG. 5. The car door 21 and the shaft door 22 therefore also stop in the position in which they can be locked. This means the closing process is quiet.
- Fig. 6 shows a side view of the elevator 100.
- the cabin 7 has a cabin door 21, which is opposite a shaft door 22.
- a control device 6 receives signals from a position measuring device 60, which determines the position along a positioning belt 61 arranged in the shaft.
- the control device 6 controls the door drive 4 and the cabin door lock and the shaft door lock.
- the signal to the shaft door lock can be sent via another control device in the machine room. to the shaft door, or for example via radio directly to the shaft door.
- the control unit 6, which is preferably arranged on the cabin can for example also forward the signals from the position measuring device 60 to a main control unit, for example in a machine room, or receive and execute commands from the main control device to open or close the door.
