Abstract

Door stop closer (1) for closing a building door (104), comprising: a carrier (2), a gripping element (3), the gripping element (3) being movably arranged on the carrier (2), and one on the carrier (2) arranged, controllable drive unit (5), designed to move the gripping element (3) in order to grip and release a counter-element (107) to close the building door (104).

Description

The invention relates to a device for closing a building door - hereinafter referred to as a door stop closer. Furthermore, the invention shows a building door system, comprising the door stop closer and a method for operating the building door system.

Door closers that are connected to the building door via levers are already known. Using the door closer, the building door can be moved over the entire opening angle - however, the closing torque of the door closer is not always sufficient to press the building door into the lock, especially against the resistance of a door seal. This requires a so-called end stop of the door closer, which uses the kinetic energy of the building door to close the building door into the end position. The disadvantage is that the end stop is set to a fixed value and does not always close reliably under changing environmental conditions, e.g. changes in temperature or wind load. In addition, the end stop in door closers is always associated with undesirable noise.

It is the object of the present invention to provide a device for closing a building door, which enables comfortable and safe operation of a building door. Furthermore, it is the object of the present invention to provide a corresponding building door system and a method for operating the building door system.

The problem is solved by features of the independent claims. The dependent claims relate to preferred developments of the invention.

The invention shows a device for closing a building door - referred to as a door stop closer. The building door is designed in particular to be accessible by people. The door stop closer can be part of a building door system. The building door and/or the building door system is/are designed in particular to be arranged in or on a building.

In particular, the door stop closer, in contrast to conventional door closers, does not permanently form a connection between the building door and the door frame, but only creates a connection between the building door and the door frame from a certain, relatively small door gap in order to close the building door in the end stop.

The door stop closer preferably has a carrier, in particular designed as a housing. This carrier is designed in particular to be installed in the door frame or in the counter box of an inactive leaf. A counter element is located on the door to be closed, especially the door leaf or door leaf. Alternatively, the carrier and thus the door stop closer can also be arranged on the door and the counter element on the door frame.

The door stop closer is preferably designed to be arranged on the door frame side and the counter element is arranged on the door side. “Door frame side” preferably also includes the arrangement on the inactive leaf of a two-leaf building door system. However, it is also provided that the door stop closer is designed to be arranged on the door side, i.e. on the door leaf, and the counter element is arranged on the door frame side.

The carrier preferably contains a gripping element which is movably arranged on the carrier. In particular, the gripping element is movable between a first position and a second position. The door can be closed in particular by moving between the two positions.

In a preferred embodiment, the gripping element is retracted into the carrier in the first position and extended out of the carrier in the second position and/or in a position gripping the counter element

In the retracted position, the gripping element does not have to be completely in the carrier of the door stop closer. Preferably, however, it is provided that the gripping element does not protrude from the carrier of the door stop closer in the retracted position or only protrudes insignificantly, so that the gripping element does not protrude into the door passage on the main closing edge in a disruptive manner. This prevents, for example, people from getting caught on the gripping element when walking through the building door.

A controllable drive unit is preferably arranged on the carrier. The drive unit is designed to move the gripping element in order to grip and release a counter-element for closing, in particular closing, the building door. By the gripping element gripping the counter element, the building door with the drive unit can be moved into the closed position and/or locked in the closed position. By releasing the counter element, the connection between the door stop closer and the counter element can be separated, so that the building door can be moved manually by a user, using a conventional door closer or a door drive.

In the door stop closer according to the invention, it is preferably provided that the gripping element is designed so that it grips the counter element in order to Close the building door, especially close it. This is particularly advantageous for completely closing the building door in a comfortable and safe manner. For example, a relatively weak conventional door closer can be used because the door closer does not have to close the building door in the end position; this can be taken over by the door stop closer according to the invention.

The "grabbing" of the counter element by the counter element describes in particular that the gripping element can be placed on the counter element, i.e. in particular comes into contact in order to press the counter element in the closing direction of the building door, whereby the building door can be closed.

While the building door is open, the gripping element is preferably in the first position. Accordingly, the drive unit is preferably designed to extend the gripping element from this position and to move it back towards the first position or to move it further towards the first position in order to close the building door.

The gripping element is preferably rotatably mounted in the carrier and rotatable by the drive unit. The gripping element is particularly preferably rotatable about a pivot axis. The pivot axis is preferably vertical or horizontal when the door stop closer is installed in the usual position.

The gripping element is preferably designed as a rotatable eccentric. In particular, the eccentric comprises an eccentric arch wall with a concave inside that is eccentric to the pivot axis of the gripping element. The concave inside is designed to grip the counter element. In particular, the counter element can rest on this inside and slide or roll on the inside when the building door is closed. Since the eccentric arch wall is eccentric to the pivot axis, the building door is closed.

Instead of using the inside of the eccentric arch wall, a cam can also be used. The cam represents an eccentric, on the outside of which the counter element rests and slides or rolls when the building door is closed.

Furthermore, the gripping element can preferably be designed as a rotatable lever. The lever can have a contact surface against which the counter element rests and can slide or roll in the direction of the pivot axis when the building door is closed.

In an alternative preferred embodiment, it is provided that the gripping element is arranged on the carrier in a linearly movable manner and can be moved linearly by the drive unit.

In particular, the gripping element is designed as a linearly movable wedge. The inclined surface of the wedge can rest on the counter element and the counter element can slide or roll on the inclined surface when the wedge is moved linearly to close the building door.

Furthermore, the gripping element can be designed as a linearly movable closing element. The closing element can grip the counter element and release it again. By moving the closing element linearly, the counter element can be pulled and the building door can thus be closed.

Furthermore, it is preferably provided that the gripping element is designed as a linearly movable or rotatable striking plate. The door stop closer must be positioned on the door frame side. The movable striking plate is movably mounted in particular on or in the carrier.

The strike plate, like a usual strike plate, has at least one strike plate recess. A door-side latch, in particular a lock latch, or a door-side latch, in particular a lock latch, can dip into the striking plate recess when the building door is closed. Preferably, the striking plate has two of the striking plate recesses one above the other, so that the latch and bolt can be immersed at the same time.

If the gripping element is designed as a strike plate, the counter element is preferably a door-side latch, in particular a lock latch, or a door-side latch, in particular a lock latch.

With the rotatable striking plate, the pivot axis is preferably vertical. Particularly preferably, the pivot axis does not intersect the at least one striking plate recess; In particular, the pivot axis is located behind the striking plate recess, so that when the striking plate is rotated, the recess can be moved into the door gap.

In the case of the linearly movable striking plate, the striking plate is preferably movable in the horizontal direction, in particular tangentially to the rotational movement of the building door.

The drive unit of the door stop closer preferably comprises an actuator. The actuator is preferably a rotating electric motor in which a rotor can be rotated relative to the stator. The gripping element can be moved via this rotatable rotor, if necessary with a corresponding translation and/or transmission means. As an alternative to the rotating electric motor, the actuator can also be designed, for example, as an electric linear motor in order to move the gripping element.

It is preferably provided that the gripping element can be moved in one direction by means of the actuator and can be moved in the opposite direction by means of the actuator; or that the gripping element can be moved in one direction by means of the actuator and can be moved in the opposite direction by means of an energy storage device, for example a spring.

The door stop closer preferably includes a door position sensor. This is arranged in particular on the carrier. The door position sensor is designed and arranged to detect a door position of the building door. For example, the door position sensor can be a magnetic sensor that can detect the metal building door as soon as the building door is close enough to the door position sensor. Particularly preferably, there is a sensor counterpart inside the building door, for example a permanent magnet, which can be detected by the door position sensor.

The drive unit is preferably designed to move the gripping element depending on the detected door position. The door position sensor detects, for example, that the building door is already closed to such an extent that there is a door gap of less than or equal to 10 mm, particularly preferably less than or equal to 8 mm, or that a door opening angle is less than or equal to 20°, preferably less than or equal to 10°, is present. With such a small door gap, it is relatively unlikely that fingers will get trapped and accordingly the drive unit can move the gripping element to close the building door.

The door stop closer is preferably also designed as a door lock. The gripping element can be moved between a releasing position for releasing the counter element element and the blocking position for locking the counter element element. The releasing position can correspond to the first position. The blocking position may correspond to the second position.

The door stop closer preferably also fulfills the function of a conventional door opener; especially if the door-side latch is used as a counter element. The gripping element of the door stop closer according to the invention fulfills the function of a conventional swivel latch of a conventional door opener. With the gripping element in the blocking position, the door-side latch can be blocked so that the building door is locked. If the gripping element moves into the releasing position, the door-side latch is released. This also releases the building door and can be opened.

Preferably, the drive unit is designed to leave the gripping element to block the lock latch after it has moved the gripping element to close the building door. In particular, the drive unit leaves the gripping element in the blocking position until the building door is requested to be opened. For this purpose, in particular a control device, for example a remote station, is used, which will be described in detail later.

If it is necessary to open the building door, the gripping element must be released. For this purpose, it is particularly preferably provided that the drive unit is designed to move the gripping element, in particular by means of the actuator; especially in the releasing position. This means that the counter element is no longer blocked and the building door can be opened. Alternatively, it is also provided that the gripping element within the door stop closer is only released, whereupon the gripping element can be pressed by the counter element and at least partially moved in the direction of the releasing position. This also makes it possible to unlock the building door.

As already described, the gripping element is preferably designed to grip a counter-element designed as a door-side latch, in particular a lock latch. Such a door-side latch can be engaged in particular against a spring force and has an inclined surface that abuts, for example, on a strike plate, whereby the latch can be engaged.

The gripping element preferably has a blocking surface. When gripping the counter element - in particular designed as a door-side latch - this blocking surface faces the counter element and thus presses on the counter element to close the building door. When the building door is closed and locked, the blocking surface lies opposite the counter element - in particular designed as a door-side latch - so that the counter element can strike the blocking surface. It is preferably provided that a recess is formed in the blocking surface. This recess is dimensioned and positioned so that the counter element - in particular designed as a door-side latch - can partially immerse itself in this recess when the building door is closed.

Furthermore, it is preferably provided that the gripping element has a convex surface. In particular, the gripping element has the blocking surface on one side and the convex surface on an opposite side. If, for example in the event of a malfunction, the gripping element is extended when the building door is open, the building door can still be closed because the counter element - designed as a door-side latch - hits the gripping element with its inclined surface and engages on the door side. In order to promote this process, the convex surface can be provided on the gripping element.

The door stop closer preferably comprises a connection for a control device, in particular a remote station, which will be described in more detail in the context of the building door system according to the invention.

The door stop closer preferably comprises a two-pole connection as a connection for the control device for connecting power supply conductors to provide a supply voltage for the drive unit. In particular, there are exactly two power supply conductors.

The individual power supply conductor can be a wire, a strand, a core or another conductor. The two-pole connection is located in particular on the carrier of the door stop closer.

The two-pole connection preferably has two terminals for connecting the two power supply conductors. The two terminals can be designed in any way; For example, with one screw each for the non-positive and current-conducting connection of the power supply conductors to a conductor track in the connection.

The door stop closer preferably includes a data unit. The data unit is preferably located on the carrier of the door stop closer. The data unit can also be referred to as a computing unit. The data unit is designed to send an output signal, in particular via at least one of the power supply conductors, and/or designed to receive an input signal sent, in particular via at least one of the power supply conductors.

The door stop closer can be operated with a two-wire cable, i.e. the two power supply conductors. Due to the data unit, not only is the power supply possible via these two power supply conductors, but data can also be exchanged via them.

In particular, it is provided that the one described two-pole connection is the only connection for conductors, i.e. the only connection for current-carrying conductors and the only connection for data-carrying conductors, on the door stop closer. In particular, no further connections are provided on the door stop closer in order to connect other conductors, in particular cables, to the door stop closer.

Preferably, the data unit is designed to modulate the output signal onto the supply voltage and/or is designed to tap the input signal modulated onto the supply voltage. By using the modulated signal on the supply voltage, the at least one power supply conductor can be used in a simple manner to transmit the data to the data unit of the door stop closer or from this data unit to the control device.

The door stop closer preferably comprises at least one sensor unit, for example the door position sensor described above. This sensor unit is designed to detect at least one variable on the door stop closer and to generate the output signal based on the detected variable. This output signal can then be sent by the data unit via the power supply conductor, in particular modulated onto the supply voltage. However, it is also possible to use the recorded variables, for example from the door position sensor, only within the door stop closer, for example to extend the gripping element based on the door position.

The quantity detected by the sensor unit can also be referred to as a state or a value.

Furthermore, it is provided to combine the sensor unit or part of the sensor unit in an assembly with the data unit or part of the data unit.

In particular, several of the sensor units can also be used in the door stop closer.

The door stop closer preferably comprises at least one sensor unit which is designed to detect a preload acting on the gripping element. This sensor unit can also be referred to as a preload sensor unit.

Additionally or alternatively, the door stop closer comprises at least one sensor unit which is designed to detect the counter element projecting towards the door stop closer. This makes it possible to detect whether the building door is closed.

The door stop closer can comprise at least one sensor unit which is designed to detect a position of a movable component of the door stop closer. This movable component of the door stop closer is in particular the gripping element. By detecting a movable component of the door stop closer, in particular the gripping element, it can be detected whether the building door is also locked. If the counter element is located on the door stop closer and at the same time the gripping element is correctly positioned, the building door is not only closed, but also locked.

Furthermore, it is preferably provided that the data unit is designed to control the drive unit based on the input signal. For example, the input signal can contain the information that the building door needs to be unlocked. In response to such an input signal, the Data unit causes the drive unit to be energized in order to unlock the door stop closer.

Furthermore, it is preferably provided that the door stop closer comprises at least one output unit. The output unit is designed to output a message on the door stop closer. The output unit preferably comprises at least one lighting unit, in particular LED. The output unit, in particular the lighting unit, is preferably located on the carrier or on the gripping element.

The output unit is in particular designed to output the message based on the input signal and/or based on at least one detected variable of the at least one sensor unit.

Additionally or alternatively, a corresponding message can also be issued outside the door stop closer, which is described in connection with the building door system.

The invention further includes a building door system. Part of this building door system is the door hinge closer, as described above. The advantageous configurations described in the context of the door hinge closer and the subclaims of the door hinge closer find correspondingly advantageous application in the context of the building door system.

Furthermore, the building door system includes the counter-element that can be grasped by the gripping element, in particular as a door-side latch or as an element fixedly arranged on the door, for example a pin-shaped element.

In particular, the door system includes a lock and the door-side latch is a latch of the lock. The lock is then located on or in the door, especially in the form of a mortise lock. The lock latch protrudes from the lock. The lock latch can be pulled in, for example, using a door handle and/or a cylinder lock. In particular, the lock is designed in such a way that the lock latch can be pushed into the lock against a spring.

The building door system preferably includes the control device described. The control device can also be referred to as a remote station. The control device is connected to the door stop closer, preferably via the power supply conductor. Preferably, the control device can send the input signal to the door stop closer and/or receive the output signal from the door stop closer. Accordingly, the control device is preferably designed: to receive the output signal sent, in particular via at least one of the power supply conductors, and/or to transmit the input signal, in particular via at least one of the power supply conductors.

The control device can be located anywhere, for example near the door frame or far from the building door inside an apartment or at a building control center.

The control device can be an independent computing unit; but can also be divided into several computing units. Furthermore, the control device can be at least partially implemented in a cloud. The control device can also be designed as a relatively simple counterpart, which is primarily used to power the door stop closer to release the building door.

As described, the control device is designed in particular to send information to the door stop closer and/or to receive information from the door stop closer. Between the door stop closer and the control unit, communication takes place in particular via the two power supply conductors and thus only via two wires. Therefore, the control device is designed in particular to modulate the input signal onto the supply voltage, so that the input signal can be sent from the control device to the door stop closer. Additionally or alternatively, the control device is designed in particular to tap the output signal modulated onto the supply voltage, i.e. the signal sent by the door stop closer.

Furthermore, the control device is preferably designed to generate an information signal based on the output signal, i.e. based on the signal received from the door stop closer. The information signal can have the same content as the output signal or can only be based on the output signal. Furthermore, the control device is preferably designed to output the output signal. This output of the output signal can take place as a radio signal or can be provided at a control device connection, in particular a potential-free connection of the control device.

Furthermore, the control device is preferably designed to receive a control signal in any way, for example via radio or wired. The control device can implement this control signal accordingly and send it as an input signal to the door stop closer via the two power supply conductors. For example, a control signal - for example to open the door - can be sent to the control device using a smartphone app or a building control unit. This converts the control signal into the input signal for the door stop closer.

Furthermore, it is provided that the building door system preferably includes a higher-level output unit that is not in the door stop closer located. This higher-level output unit can be designed to output a message. The message is output in particular based on the information signal. The higher-level output unit can, for example, have a lighting unit and/or an acoustic output device (e.g. loudspeaker) and/or a corresponding display for outputting the message.

The higher-level output unit can be combined in a unit with the control device. Alternatively, it is also possible for the higher-level output unit to be located anywhere and to be connected to the control device in terms of information technology.

The invention further includes a method for operating a building door system. In particular, this concerns the building door system described above. The method involves using a door stop closer. In particular, this is the door stop closer described above. The advantageous embodiments and associated subclaims described in the context of the building door system and/or the door stop closer are particularly preferably used in an advantageous manner within the framework of the method.

Furthermore, a control device, in particular the control device described above, is preferably used in the method. The control device is preferably connected to the door stop closer via the power supply conductor.

The method further provides that the gripping element of the door stop closer is moved, in particular extended, and thereby grips the counter element, in particular the door-side latch, to close the building door. “Gripping” is at least to be understood as meaning that the gripping element comes into contact with the counter-element in order to press on the counter-element.

It is preferably provided that, as part of the method, the gripping element is left in a blocking position for blocking the counter-element and thus for locking the building door. In particular, the gripping element is left in this blocking position for several minutes, hours or days.

Particularly preferably, the gripping element is left in the blocking position for locking the building door until the door stop closer is activated by an external control device to release the counter element and thus to release the building door. In the simplest case, the drive unit is energized via the control device, for example designed as a counterpart, in order to move the gripping element in the direction of the releasing position. However, it is also possible for the control device to send a corresponding command to electronics, for example the data unit, in the door stop closer and, in response, the door stop closer energizes the drive unit to move the gripping element or otherwise releases the gripping element.

Furthermore, as part of the method, it is preferably provided that a door position of the building door is detected and the gripping element is moved to grip the counter element depending on this door position. In particular, the gripping element moves to grip the counter element when a door gap on the main closing edge is less than or equal to 10 mm, preferably less than or equal to 8 mm; or in particular if a door opening angle is less than or equal to 20°, preferably less than or equal to 10°.

As part of the method, an output signal, in particular the output signal described above, is preferably received, in particular sent via at least one of the power supply conductors, and/or sending an input signal, in particular the previously described input signal, preferably via at least one of the power supply conductors.

Method steps of the method according to the invention according to all exemplary embodiments.

Fig. 1 , 5 and 8th show a building door system 100 according to the invention for different exemplary embodiments. This building door system 100 includes a building door 104, designed as a revolving door. Furthermore, the building door system 100 includes a door frame 105 with a door stop closer 1 arranged therein.

On the door frame 105 there is a purely optional door actuator 108, designed as a door closer, which is connected to a slide rail 110 via a lever 109. The slide rail 110 is located on the building door 104. This allows the door operator 108 to close the building door 104 after the building door 104 is manually opened.

Furthermore show Fig. 1 , 5 and 8th purely schematically a control device 101, for example designed as a counterpart. The control device 101 is connected to the door stop closer 1 for data and/or energy transmission. In particular, it is provided that the control device 101 is connected to the door stop closer 1 via two power supply conductors 102. The data transmission is preferably carried out using modulated signals on the power supply.

The control device 101 may include a control device connection 103 for outputting and/or receiving data. Additionally or alternatively, the control device 101 can also output and/or receive data wirelessly.

There is a lock 106 in the building door 104, designed as a mortise lock. This lock 106 has a door-side latch (lock latch). In the first two exemplary embodiments ( Fig. 1 to 7 ), the door-side latch forms a counter element 107. In the third exemplary embodiment ( Fig. 8 to 14 ), an independent counter element 107 is firmly arranged on the building door 104.

For the first exemplary embodiment, the Fig. 2 to 4 the schematic structure of the door stop closer 1 and its interaction with the counter element 107:

The door stop closer 1 includes a carrier 2 which is used to fasten the door stop closer 1 in the door frame 105. In the carrier 2 there is a gripping element 3, which is rotatably mounted in the carrier 2 about a pivot axis 4.

Furthermore, there is a drive unit 5 with an actuator 6 in the carrier 2. This drive unit 5 with actuator 6 is shown purely schematically. By means of the drive unit 5 and the actuator 6, the gripping element 3 can be rotated about the pivot axis 4, so that the gripping element 3 can be retracted into a first, retracted position and can be extended into a second, extended position.

Fig. 2 shows the gripping element 3 in the retracted position. The gripping element 3 is located almost completely in the carrier 2. In particular, it can be seen that in this position the gripping element 3 no longer protrudes into the gap on the main closing edge.

Fig. 3 shows a state while the gripping element 3 is being extended by the drive unit 5 - i.e. is currently moving into the extended position.

Fig. 4 shows the extended position of the gripping element 3 and the closed state of the building door 104. It can be seen that in this state the building door 104 is locked in that the counter element 107 is blocked by the gripping element 3.

The gripping element 3 has a blocking surface 7. The counter element 107 strikes this blocking surface 7 when the building door 104 is locked (see Fig. Fig. 4 ) at. Opposite, the gripping element 3 has a convex surface 9. A recess 8 in a semicircular shape is provided in the blocking surface 7. How Fig. 3 clarified, the counter element 107 can dip into this recess 8, while the counter element 107 is gripped by the gripping element 3 and the building door 104 is closed.

In the second exemplary embodiment according to Figures 5 to 7 is the gripping element 3 as a linearly movable ( Fig. 6 ) or rotating ( Fig. 7 ) striking plate is formed. The door stop closer 1 is arranged on the door frame side. The movable striking plate is movably mounted in particular in the carrier 2.

The gripping element 3 - designed as a striking plate - has, like a usual striking plate, at least one striking plate recess 11. The counter element 107 - designed as a door-side latch - can dip into the striking plate recess 11 when the building door 104 is closed.

In the case of the linearly movable gripping element 3 - designed as a striking plate - according to Fig. 6 the striking plate can be moved in the horizontal direction. The drive unit 5 with the actuator 6 is located on the carrier 2. By means of the drive unit 5 and the actuator 6, the gripping element 3 can carry out a linear movement 12, so that the gripping element 3 can be moved between the first and second positions.

In the rotatable gripping element 3 - designed as a striking plate - according to Fig. 7 the pivot axis 4 is vertical. The drive unit 5 with the actuator 6 is located on the carrier 2. By means of the drive unit 5 and the actuator 6, the gripping element 3 can be rotated about the pivot axis 4, so that the gripping element 3 can be moved between the first and second positions.

In the third exemplary embodiment according to Figures 8 to 14 the counter element 107 is arranged outside the lock 106 on the building door 104. According to Fig. 8 Counter element 107 and door stop closer 1 are located on the main closing edge. Additionally or alternatively, counter element 107 and door stop closer 1 can also be arranged on the upper secondary closing edge 112 or on the lower secondary closing edge, not shown.
