Description

[0001] The present invention relates to a device for opening and / or closing a leaf of a revolving door, comprising a drive unit with a first communication element, at least one first sensor device arranged on one side of the leaf, and a second control unit associated with the first sensor device, comprising a second communication element configured to transmit sensor signals to the first communication element. The invention further relates to a method for opening and / or closing a leaf of a revolving door.

[0002] Various methods for securing revolving doors are known in the art. Conventional solutions, for example, use optical sensors mounted on the door leaf. These moving sensors offer the advantage that the monitoring field is always within the danger zone and the sensor is not obstructed by the door leaf. However, wiring these sensors requires complex installations, especially for fire doors, where drilling through the door is often not possible. The high energy consumption of the sensors also poses a challenge for battery operation, necessitating the use of cable transitions between the sensor and the drive mechanism.

[0003] Existing energy transfer solutions include contact-based methods, such as wipers that establish a conductive connection, and contactless methods, such as inductive charging, which converts electromagnetic radiation into electrical energy. Despite these approaches, the challenge remains to ensure efficient and reliable energy and signal transmission without compromising the structural integrity of the door.

[0004] The object of the present invention is therefore to further develop a device of the aforementioned type in such a way that simple assembly and safe operation are made possible. In particular, the device should overcome the aforementioned disadvantages.

[0005] This problem is solved by a device having the features specified in claim 1. Advantageous embodiments are defined in the dependent claims.

[0006] The device according to the invention for opening and / or closing a leaf of a revolving door has the following features: a drive unit comprising a first control unit with a first communication element, at least a first sensor unit arranged on one side of the leaf, and a second control unit associated with the first sensor unit with a second communication element configured to transmit sensor signals to the first communication element.Furthermore, an energy transmission unit is provided that is fixed to the drive unit, as well as an energy conversion element and an energy storage element, which are assigned to the first sensor device, wherein in at least one predetermined position of the wing the energy conversion element cooperates with the energy transmission unit to transfer energy and charge the energy storage element, and wherein the first and the second communication element are configured to transmit the sensor signal wirelessly.

[0007] The solution according to claim 1 offers numerous advantages.

[0008] Wireless transmission of sensor signals eliminates the need for wiring between the sensor and the drive unit, simplifying installation and reducing the effort and costs associated with cabling and maintenance. No cable penetrations are required in the door leaf, thus preserving the structural integrity of the door, especially in the case of fire doors. This is particularly important because drilling into fire doors is often prohibited. Installation time is also reduced thanks to wireless communication and the stationary power transmission unit, as fewer mechanical and electrical connections are required.

[0009] The flexibility in component placement is increased because the stationary power transmission unit and wireless communication allow components to be positioned independently of cable routing. Furthermore, the reliability of the device is enhanced by avoiding cable breaks or contact problems that can occur with conventional wired systems. Finally, the solution enables an aesthetically pleasing arrangement of the sensor system, as there are no visible cables or wires, which is particularly advantageous for doors in design-critical environments.

[0010] The task is thus completely solved.

[0011] In a preferred further development, the energy storage element includes a rechargeable battery or a capacitor.

[0012] The advantage of this measure is to enable a durable and reusable energy source that ensures the operation of the sensor device even with frequent use.

[0013] In a preferred training program, energy transfer occurs wirelessly.

[0014] This measure has the advantage of avoiding the need for physical connections, which simplifies installation and reduces mechanical wear.

[0015] In a preferred further development, energy transfer occurs inductively, capacitively, thermally, kinetically, acoustically or optically.

[0016] This measure offers flexibility in the choice of energy transmission technology to utilize the best method for different applications and environments.

[0017] In a preferred further development, the energy transfer is inductive and the energy transfer unit and the energy conversion element each have a coil.

[0018] The advantage of this method is that inductive energy transfer enables efficient and contactless energy transmission, thus minimizing wear and maintenance. Furthermore, this type of energy transfer is a structurally simple and cost-effective solution.

[0019] In a preferred method of further development, energy transfer occurs via contact, with the contact being made in a predetermined position. Of course, energy transfer using contacts and cables is also conceivable.

[0020] This measure ensures reliable and interference-resistant energy transmission in specific positions of the door using simple technical means.

[0021] In a preferred further development, the energy conversion element, the energy storage element and the second control unit are housed separately from the sensor device in a separate enclosure, and an electrical connection to the sensor device is provided to transmit energy and sensor signals.

[0022] This measure has the advantage that a modular design makes it easier to maintain and replace individual components without having to replace the entire sensor system.

[0023] In a preferred further development, the energy conversion element, the energy storage element and the second control unit are included in one housing of the sensor device.

[0024] This measure results in a compact design that reduces space requirements and simplifies integration into existing door systems.

[0025] In a preferred further development, a second sensor device, a third control unit with a third communication element, a second energy conversion element and a second energy storage element are provided on the other side of the wing, and the energy transfer unit is configured to cooperate with the second energy conversion element of the second sensor device and to charge the second energy storage element in a predetermined position of the wing.

[0026] This measure leads to improved safety features by monitoring and powering both sides of the door leaf via two sensor devices.

[0027] In a preferred further development, the energy storage element is designed to store the energy for at least one, preferably two or more opening and / or closing cycles.

[0028] This measure ensures that the sensor system operates reliably even with repeated opening and closing of the door. Overall, this increases the robustness of the operation.

[0029] In a preferred further development, the energy transfer unit is provided in a frame of the revolving door, with the energy transfer taking place in the closed position of the wing.

[0030] This measure allows for an optimal placement of the energy transfer unit from a design perspective, ensuring efficient charging in the door's rest position.

[0031] In a preferred further education system, the first and second communication elements each have a sending and receiving element.

[0032] This measure enables bidirectional communication for more precise control and monitoring of the sensor system.

[0033] In a preferred further development, each transmitting and receiving element has an antenna for transmitting and receiving radio signals.

[0034] This measure improves the range and reliability of wireless communication between the sensor and the drive unit.

[0035] The object of the present invention is also achieved by a method for operating a sensor device on a leaf of a revolving door with the features of claim 14. The method comprises, in particular, the following steps: transferring energy from a stationary energy transfer unit to an energy conversion element provided on the leaf when the leaf is in a predefined position; charging an energy storage element provided on the leaf with the transferred energy; supplying a sensor device provided on the leaf with energy from the energy storage element while the leaf is moving in order to operate the sensor device; and wirelessly transmitting sensor signals generated by the sensor device to a stationary communication element.

[0036] In a preferred further development, energy is transmitted wirelessly. A further preferred configuration is the predefined position, which is the closed position of the wing.

[0037] The method according to the invention has the same advantages that have been explained in connection with the device according to the invention, so that a repetition at this point can be omitted.

[0038] The object of the present invention is also achieved by an assembly comprising a control unit configured to be connectable to a control unit of a drive device, so that control signals can be transmitted to the control unit; a communication element configured to receive sensor signals from a sensor device, preferably wirelessly; and an energy transmission unit configured to receive electrical energy, preferably from a power supply unit, and to transmit energy, preferably wirelessly, to a further assembly.

[0039] The object of the present invention is also achieved by an assembly comprising a control unit designed to be connectable to a sensor device so that sensor signals can be received from the sensor device and electrical energy can be supplied to the sensor device; a communication element designed to send sensor signals from the sensor device, preferably wirelessly; an energy conversion element designed to receive energy, preferably wirelessly transmitted; and an energy storage element designed to store the energy provided by the energy conversion element and preferably supply it to the control unit at a time delay.

[0040] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0041] Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings. These show: Figure 1: A schematic representation of a revolving door system; Figure 2: A schematic block diagram of the first assembly; Figure 3: A schematic block diagram of the second assembly; Figure 4: A schematic side view of the revolving door system. Figure 1 Figure 5 shows a schematic side view of the revolving door system of Figure 1 with alternatively arranged first and second assemblies; and Figure 6 a schematic block diagram of the method according to the invention.

[0042] The following describes, in the form of an exemplary embodiment, a device, for example, a motor-driven revolving door operator for a revolving door. Such a revolving door operator essentially consists of several components that work together to ensure the smooth and automatic movement of one door leaf (hereinafter referred to as "leaf") of a revolving door. The main components include an electric motor, a control unit, power transmission elements, and a sensor system with at least one safety sensor.

[0043] The drive is provided by an electric motor, which supplies the necessary energy to set the revolving door leaf in motion. The electric motor is housed in a casing, which is typically mounted above the door leaf on the door frame, the door head, or the wall. The control unit processes signals from various sensors and control devices and relays commands to the electric motor. The control unit regulates, for example, the speed, the opening and closing cycles, and the safety functions of the revolving door.

[0044] The power transmission elements comprise mechanical components such as gears, joints, and arms that transfer the rotary motion of the electric motor to the door leaf of the revolving door. These elements ensure that the motor's power is transferred to the door leaf evenly and efficiently.

[0045] The intended sensor device, comprising at least one sensor, such as a presence sensor, is typically installed on at least one side of the door leaf to ensure that the door leaf only moves when it is safe to do so, i.e., when no person or obstacle is within the leaf's range of motion. Such sensors include presence sensors, safety sensors, backup sensors, or, more generally, sensors that detect people or obstacles near the door leaf, particularly within its range of motion, and can trigger a stop or reversal of the motor.

[0046] During operation, the drive receives a signal from a manual control unit (for example, a button or a remote control). The control unit processes this signal and activates the electric motor, which sets the door leaf in motion via the power transmission elements. During movement, the sensor system continuously monitors the area around the door leaf to ensure that no people or obstacles are in its path. Once the door leaf has reached the desired position (fully open or closed), the motor stops or reverses automatically.

[0047] In Figure 1 A schematic representation of such a device 10 for a door leaf 24 of a revolving door 20 is shown. The door leaf 24 is held pivotally or rotatably on a door frame 22 of the revolving door 20 by means of door hinges 25.

[0048] The device 10 has a housing 16 which contains a control unit 17 and a drive unit 12 required for the drive, with components such as an electric motor, torque transmission elements and a Figure 1 visible output shaft 19. Outside the housing 16, an arm 18 is provided as one of the force transmission elements, which is coupled on one side to the output shaft 19 and on the other side to a slide rail 26, which is attached to the door leaf 24 and serves to open and / or close the door leaf 24 via the drive.

[0049] In the present embodiment, the housing 16 is attached to the door frame 22 or a door lintel 28, so that the housing 16 is fixed in position relative to the door leaf 24.

[0050] Below the guide rail 26, a sensor device 30 is provided on the door leaf 24. This sensor device has a housing 32 in or on which at least one sensor 34, or in the present embodiment three sensors 34, are provided. The three sensors 34 are evenly distributed in order to monitor as much of the area directly in front of the door leaf 24 as possible via their individual monitoring areas 36.

[0051] The sensors 32 are basically designed to detect people and / or obstacles in the area in front of the door leaf 24. The term "in front" is to be understood relative to the direction of movement of the door leaf 24.

[0052] Different types of sensors can be used, such as optical sensors, acoustic sensors, time of flight sensors, LiDAR sensors, triangulation sensors, ultrasonic sensors or the like.

[0053] In Figure 1A first assembly 40 is shown schematically, which is fixedly mounted on the frame 12 and associated with the housing 16, and can be electrically connected to the control unit 17, for example. Furthermore, a second assembly 50 is shown schematically, which is fixedly mounted on the door leaf 24 and associated with the sensor device 30, and can be electrically connected to it, for example.

[0054] It should be noted at this point that both assemblies 40, 50 in Figure 1The components are shown as separate assemblies, but this is only one of several possible arrangements. Of course, assembly 40, or individual elements thereof, could be housed in the casing 16, or assembly 50, or individual elements thereof, could be housed in the casing 32 of the sensor device. For example, it would be conceivable to house individual elements of assembly 40 in a door frame and individual elements of assembly 50 in the door leaf. Alternatively, individual elements of assembly 40 could be mounted on a wall or ceiling in the area of ​​the revolving door 20. It would also be conceivable to design the control unit 40 of the first assembly and the control unit 17 as a single unit.

[0055] In Figure 2The assembly 40 is represented in the form of a block diagram showing its elements. The assembly 40 comprises a first control unit 41, which is connected to the control unit 17 in the housing 16 in order to transmit energy and data signals or sensor signals. Furthermore, the assembly 40 includes a power transmission unit 44 and a first communication element 42.

[0056] In Figure 3 The second functional assembly 50 is shown in the form of a block diagram with its elements. Assembly 50 comprises a second control unit 51, which is connected to a corresponding control unit (not shown) of the sensor device 30 in order to transmit energy and data signals or sensor signals. Assembly 50 also includes a second communication element 52, an energy conversion element 54, and an energy storage element 56.

[0057] The energy transfer unit 44 of the first assembly serves to transfer electrical energy, which is received by the energy conversion element 54 of the second assembly and fed into the energy storage element 56. The energy storage element 56 then serves to supply the elements in the second assembly 50, as well as the elements provided in the sensor device 30, with electrical energy for their operation. In other words, there is no permanent wired power supply between the housing 16 and the sensor device 30.

[0058] The transfer of electrical energy from the energy transfer unit 44 to the energy conversion element 54 is temporary. In particular, the transfer does not occur during an opening and closing cycle of the door leaf 24. In the present embodiment, the transfer of electrical energy takes place in the closed position of the door leaf 24.

[0059] The transmission of electrical energy in the closed position of the door leaf 24 can be either contact-based or contactless. Contactless energy transmission, for example inductive energy transmission, is preferred. For this purpose, one or more coils are provided in the energy transmission unit 44 and the energy conversion element 54, wherein the coil of the energy transmission unit 44 generates an electromagnetic field that is received by the coil in the energy conversion element 54 and converted into electrical energy.

[0060] Of course, other types of contactless energy transfer are also conceivable. Energy transfer could be capacitive, thermal, kinetic, acoustic, or optical.

[0061] If contact-based energy transfer is used instead of the preferred contactless energy transfer, the energy transfer unit 44 has, for example, two or more contact pins or contact wipers which interact with correspondingly provided contact surfaces on the energy conversion element 54 when the door leaf is closed.

[0062] The energy storage element 56 is designed to store at least the amount of energy required to operate the sensor device 30 for one opening and / or closing cycle of the door leaf 24. Preferably, however, the energy storage element 56 is designed to store more energy, so that operation of the sensor device 30 is possible for two or more opening and / or closing cycles.

[0063] The energy storage element 56 is preferably a rechargeable battery, such as a NiCd, NiMH, Li-ion, LiPo, LiFePO4, zinc-air, or Ni-Zn battery, or a capacitor. Of course, other energy storage elements for storing electrical energy are also conceivable. In this context, it should also be noted that the energy conversion element 54 includes all the necessary components (e.g., charging electronics) required to transfer the received electrical energy to the energy storage element 56.

[0064] In addition to the transmission of electrical energy from the control unit 17 in the stationary housing 16 of the device 10, the operation of the device 10 also requires that the sensor signals generated by the sensors 34 of the sensor device 30 be transmitted to the control unit 17 for controlling the drive device 12. This transmission of the sensor signals is wireless, so that no fixed wiring between the sensor device 30 and the stationary housing 16 is required.

[0065] To ensure wireless transmission of the sensor signals, two communication elements 42 and 52 are provided. The second communication element 52 receives the signals from the sensor device 30 via the second control unit 51 and generates a signal from them that is transmitted wirelessly to the first communication element 42. The first communication element 42 receives the sensor signals and delivers them via the first control unit 41 to the control unit 17 in the housing 16. Depending on the sensor signal received, the drive, and thus the movement of the door leaf 24, can be stopped or reversed if a person or obstacle is detected in the door leaf's range of motion.

[0066] Wireless transmission can occur in various ways, such as optical, acoustic, or radio-based. However, a radio-based transmission technology with low energy consumption is preferred.

[0067] As previously explained, the elements of the two assemblies 40 and 50 can be housed in the housing 16 and the housing 32 of the sensor device 30, respectively. Figure 4 For example, a side view schematically shows that the first assembly 40 is provided in the housing 16, while the second assembly 50 is attached to the door leaf above the sensor device 30 or its housing 32.

[0068] Alternatively, it would also be conceivable to do as in Figure 5 shown, the first assembly 40, or at least only the energy transmission unit 44, is to be placed in the door frame 22 and the second assembly 50, or at least only the energy conversion element 54, is to be provided within the door leaf 24 in the area of ​​the energy transmission unit 44.

[0069] Of course, it would also be conceivable to mount the energy transmission unit 44 on the wall or ceiling near the revolving door 20, while the second assembly 50 is attached to the door leaf 24. It goes without saying that in such a case, the energy transmission unit 44 must be capable of transmitting electrical energy over a greater distance.

[0070] The first assembly 40 is connected to the control unit 17 in the housing 16 of the device 10. Electrical power is transmitted from the control unit 17 to the first assembly 40, and sensor signals are transmitted from the first assembly 40 to the control unit 17 via this connection. Alternatively, the electrical supply for the first assembly 40 could be provided independently of the control unit 17 in the housing 16 via a separate power supply unit. In this case, only one electrical connection for transmitting the sensor signals between the first assembly 40 and the control unit 17 would be required.

[0071] Both the first module 40 and the second module 50 can be provided as separate units in a housing, allowing them to be retrofitted to a revolving door 20. Only the wiring between the first module 40 and the control unit 17, and between the second module 50 and the sensor unit 30, needs to be provided in this case.

[0072] While a second sensor unit is typically provided on the hinge side of the door leaf, an additional first assembly and a further second assembly can also be provided on this side. The energy for operating the second sensor unit would then be supplied via the further second assembly, with the corresponding energy storage element supplied via the further first assembly and its integrated energy transfer unit. Alternatively, wiring between the second assembly and the further second assembly could be routed through the door leaf, resulting in wired energy transfer. It would also be possible to receive the sensor signals from the further second assembly via the first assembly, thus eliminating the need for a further second assembly on the hinge side.Of course, other combinations or constellations of first and second assemblies on the hinge side and the opposite hinge side of the door leaf or the revolving door 20 are also conceivable.

[0073] In Figure 6 A method for opening and / or closing a door leaf is now shown as a block diagram. In a first step 70, energy is transferred from the energy transfer unit 44 to the energy conversion element 54, which is provided on the leaf, when the leaf is in a predefined position, e.g., the closed position. The energy transfer can be contact-based or contactless. Preferably, the transfer is contactless, e.g., inductive.

[0074] In the next step 72, the energy storage element 56, which is provided on the door leaf, is charged with the transferred energy. Subsequently, when the door leaf is moved via the drive unit 12, in step 76 the sensor unit 30 is supplied with energy from the energy storage element 56 in order to operate the sensor unit 30.

[0075] In the next step 78, the sensor signals generated by the sensor device 30 are wirelessly transmitted to the first communication element 42 in order to control the drive device 12 depending on the sensor signals.

[0076] In summary, it is evident that the described device according to the invention provides a solution that is easy to install, since no drilling is required for wiring between the sensor device 30 and the control unit 17.
