Description

[0001] The invention relates to a drive system comprising a main unit and an auxiliary drive device for the auxiliary drive of a building closure element that can be driven by the main drive unit. Furthermore, the invention relates to the use of an auxiliary drive device for the auxiliary drive of a building closure element that can be driven by a main drive unit.

[0002] EP 2 725 177 A1 discloses a main drive unit for driving a sectional door. The main drive unit comprises an electric motor as the motor drive device and a traction mechanism in the form of a V-belt, which connects a driven rotary member of the electric motor to a drive rotary member of a gearbox of the sectional door in the form of a rotating shaft of a weight compensation system. In the event of a power failure or other malfunction, an operator can pivot the electric motor using a clutch to release the tension of the V-belt and thus decouple the rotating shaft of the weight compensation system from the electric motor. The user can then open and close the sectional door, which is balanced by the weight compensation system, by manually pushing it open and closed.

[0003] Auxiliary drive devices for door drives, for example in the form of emergency hand chain drives, are known from the general state of the art. These auxiliary drive devices serve to ensure that a door, such as a garage door, that can be operated by a door drive can be opened and / or closed even in the event of a malfunction, such as a power failure. In particular, EP 1 028 223 A2 discloses such an auxiliary drive device with the features of the preamble of claim 1.

[0004] The object of the invention is to provide a drive system with an improved auxiliary drive device and a use of an improved auxiliary drive device in a drive system, wherein the auxiliary drive device, in particular in terms of gear technology, is constructed in a particularly simple, space-saving and reliable manner and can be operated in a particularly simple and reliable manner for the auxiliary driving of a building closure element that can be driven by a main drive unit in the event of a malfunction, such as a power failure.

[0005] This object is achieved by a drive system and by a use having the features of independent patent claims 1 and 14. Advantageous embodiments are the subject of the subclaims. To achieve this object, the invention provides a drive system with a main drive unit and an auxiliary drive device for the auxiliary drive of a building closure element that can be driven by the main drive unit. The auxiliary drive device is arranged on a B-side of the main drive unit. "B-side" refers in particular to a B-shield or a B-bearing shield of the main drive unit. Furthermore, the invention provides a use of an auxiliary drive device for the auxiliary drive of a building closure element that can be driven by the main drive unit.The auxiliary drive device can be configured to move the building closure element from a closed position into an at least partially, i.e., fully or partially, open position, or from the at least partially open position into a closed position. "Drive" refers in particular to actuating and / or moving and / or opening and / or closing the building closure element. The building closure element can be, for example, a door, in particular a garage door, particularly preferably a sectional door or a roller shutter door. The main drive unit is preferably designed as a motor, in particular as a 400 / 230 V AC three-phase / alternating current motor. For example, the main drive unit can be the WA500 drive or a drive from the 400 / 500 series from Hörmann KG. The auxiliary drive device has a motor drive device.The drive device is preferably designed as an electric machine, particularly preferably as a DC motor, in particular a low-voltage DC motor, more particularly a 24 V DC DC motor. The auxiliary drive device is particularly preferably designed as a power-operated and / or battery-buffered auxiliary drive device with a (e.g. 24 V DC) DC motor for motor-driven driving of a building closure element or building closure. The drive device is preferably designed as an independent DC motor. According to the invention, the auxiliary drive device, more specifically the drive device, is supplied with power, in particular temporarily, by a battery or an accumulator. The drive device of the auxiliary drive device can be activated or switched on, for example, by a control system, for example in the event of a fault, such as a power failure, or by an AC72 fresh air control system from Hörmann KG.Particularly preferably, the auxiliary drive device, in particular the drive means, can be operated with the AC72, which can in particular draw power independently from a battery system.

[0006] The auxiliary drive device further comprises a first transmission device and a second transmission device, wherein the first transmission device comprises a drive rotary member and an output rotary member. The first transmission device can also be referred to as the first gear stage or 1-stage of a two-stage transmission of the auxiliary drive device. The first transmission device further comprises a traction means which couples the drive rotary member and the output rotary member. In other words, the drive rotary member and the output rotary member can be connected via the traction means. In particular, the traction means wraps around or encloses the drive rotary member and the output rotary member. The traction means is designed in particular as a chain, preferably as an endless chain. Furthermore, the drive device is configured to drive the drive rotary member of the first transmission device."Driving" refers, in particular, to rotating, actuating, or moving the drive rotary member. Actuating the drive device causes the drive rotary member to rotate in a circumferential direction. For example, the drive rotary member is arranged or fastened to a shaft of the drive device, in particular by positive locking. If the shaft of the drive device rotates, the drive rotary member arranged thereon also rotates, in particular automatically. The drive rotary member can be designed, for example, as a pinion or drive pinion. The traction means is configured to transmit movement from the drive rotary member to the output rotary member. In other words, the traction means can be used to transmit movement and / or force and / or torque between the mutually spaced rotary members—the drive rotary member and the output rotary member.In particular, if the drive rotary member is rotated or driven by the drive device, the driven rotary member is rotated or set in motion by the traction means, which is moved or set in motion by a movement of the drive rotary member, or a torque is exerted or transmitted to the driven rotary member, or the driven rotary member is rotated about a rotational axis. The driven rotary member is preferably designed as a sprocket. In particular, the teeth of the drive rotary member and the driven rotary member engage with the traction means. Particularly preferably, the first transmission device forms a chain transmission.

[0007] Furthermore, the output rotary member is pivotable, designed for coupling to a rotary member of the second gear device for auxiliary driving of the building closure element. In particular, the output rotary member can be pivoted or displaced. In other words, the output rotary member can perform a pivoting movement. In other words, the output rotary member can be displaced or moved back and forth from one position to at least one further position. In particular, the output rotary member is mounted such that the output rotary member, in particular in its entirety, can be pivoted or moved from one position to a further position different from the first position. In particular, the output rotary member can be pivoted in a rotational plane of the output rotary member or a plane extending perpendicular to a rotational axis of the output rotary member.In particular, the output rotary member can move along an arcuate path of motion during pivoting. Particularly preferably, the output rotary member is designed as a pivoting sprocket. This results in the advantage that the auxiliary drive device, in particular the transmission, is particularly reliable and space-saving.

[0008] Advantageously, the second transmission device comprises a first rotary member, wherein the output rotary member of the first transmission device is configured to transmit a torque or a movement to the first rotary member of the second transmission device. In particular, the second transmission device is connected downstream of the first transmission device. Preferably, the transmission of the auxiliary drive device, which comprises the first transmission device and the second transmission device, is designed as a 2-stage transmission. The second transmission device can also be referred to as the second gear stage or 2-stage of the two-stage transmission of the auxiliary drive device. Preferably, the output rotary member is coupled or connected to the first rotary member, in particular connected in a form-fitting or non-positive manner. Preferably, the output rotary member is arranged at an end region or an end of the first rotary member.The first rotary member is preferably designed as a gear. If, in particular, the output rotary member is rotated, driven, or moved, preferably by the drive rotary member, the first rotary member is rotated or set in motion, or a torque is transmitted to the rotary member, or the first rotary member is rotated about a rotational axis. Thus, if, in particular, the output rotary member rotates, the first rotary member is preferably also rotated. Particularly preferably, an axis of rotation of the output rotary member coincides with an axis of rotation of the first rotary member. This offers the advantage that the gear stages can be coupled to one another particularly easily and reliably.

[0009] An advantageous development provides that the first rotary member of the second transmission device is pivotally mounted, in particular together with the output rotary member. In other words, the output rotary member and the first rotary member can be pivoted or displaced. In other words, the output rotary member and the first rotary member, in particular together, can perform a pivoting movement. In other words, the output rotary member and the first rotary member can be displaced or moved back and forth from one position to at least one further position. In particular, the output rotary member and the first rotary member are mounted such that the output rotary member and the first rotary member can be pivoted or moved from one position to a further position different from the first position.In particular, the output rotary member and the first rotary member can be pivoted in a rotational plane of the output rotary member and the first rotary member or a plane extending perpendicular to a rotational axis of the output rotary member and the first rotary member. In other words, the output rotary member and the first rotary member can be pivoted or moved about a common pivot point or pivot axis. In particular, when pivoting the output rotary member and the first rotary member, the output rotary member and the first rotary member move along the same arcuate trajectory.

[0010] Preferably, the second transmission device comprises a second rotary member, wherein the output rotary member and / or the first rotary member are pivotally mounted relative to the second rotary member, wherein in a rest position, the output rotary member and / or the first rotary member and the second rotary member are decoupled. "Rest position" means, in particular, that the first transmission device and / or the second transmission device are not actuated, i.e., are at rest.

[0011] The second rotary member is particularly preferably designed as an internal gear or a ring gear. Furthermore, the second rotary member preferably comprises teeth which in particular have a triangular cross-section and are arranged at equal distances from one another over a circumference. In particular, the first rotary member and the second rotary member are designed as a gear pair. The gear pair preferably forms the second stage of the transmission. The second rotary member preferably surrounds or encloses the first rotary member. In other words, the first rotary member is arranged radially inward of the second rotary member. In particular, the first rotary member is arranged in a space of the second rotary member surrounded by internal teeth. The first rotary member preferably has external teeth and the second rotary member preferably has internal teeth. The first rotary member and the second rotary member are preferably annular.The second rotary member can have an annular region surrounding the first rotary member, which is provided with a toothed region on its outer circumference. Furthermore, an inner diameter of the annular region of the second rotary member is larger than an outer diameter, in particular of the toothed region, of the first rotary member. The second rotary member has the annular region, which is provided, for example, with internal teeth and surrounds the first rotary member or at least its toothed region. The second rotary member could, for example, be designed entirely as a ring, but a pot shape or the like would also be possible. The first rotary member can be annular or tubular. Preferably, a length of the first rotary member, which extends along the axis of rotation of the first rotary member, can be designed to be larger than a diameter of the first rotary member.

[0012] Advantageously, the first rotary member is pivotally mounted relative to the second rotary member, wherein the first rotary member is pivotable from a rest position parallel to a plane of rotation such that a toothed region of the first rotary member is at least partially, i.e. completely or partially, engaged with a toothed region of the second rotary member. In other words, from the rest position, the first rotary member can be pivoted or moved towards a toothed region of the second rotary member such that the teeth of the toothed regions, in particular the teeth of the external toothing of the first rotary member and the teeth of the internal toothing of the second rotary member, mesh with one another. In other words, from a rest position, the first rotary member and the second rotary member mesh with one another with at least one rotational movement in their respective planes of rotation. The teeth of the rotary members preferably mesh with one another in a form-fitting manner.The output rotary member can be coupled or is coupled to the second rotary member, in particular via the first rotary member, particularly during the pivoting movement of the output rotary member and / or the first rotary member. In particular, the first rotary member forms an intermediate member between the output rotary member and the second rotary member. This allows the first and second rotary members to be coupled to one another particularly easily and reliably. The coupling of the rotary members or the engagement of the first rotary member and the second rotary member forms, in particular, a transmission gear.

[0013] The first rotary member can be coupled to the second rotary member, in particular for auxiliary driving.

[0014] Preferably, the first rotary member and the second rotary member are decoupled from each other in the rest position. In particular, in the rest position, the teeth of the external toothing of the first rotary member cannot engage with the internal toothing of the second rotary member. In other words, the teeth of the two rotary members cannot be brought into engagement with each other in the rest position. In other words, the teeth of the two rotary members of the second gear device cannot touch each other in the rest position.

[0015] An exemplary embodiment is described below: The first rotary member and the second rotary member are preferably designed as the drive member and output rotary member of a transmission gear. The two rotary members - first rotary member and second rotary member - are movable relative to one another in their respective radial directions, or at least one of the rotary members is mounted so as to be movable relative to the other rotary member. In the rest position or a rest position, the first rotary member and the second rotary member are decoupled from one another. By means of relative movement towards one another in the rotational plane of at least one of the rotary members, the circumferentially extending toothing regions of the two rotary members are brought into engagement, thus coupling the two rotary members to one another. This eliminates the need for a separate coupling device. The engagement or toothing regions extend essentially circumferentially, meaning that inclined toothing regions are also possible.

[0016] A further exemplary embodiment is described below: If the drive rotary member is actuated and a force is thus exerted on the traction mechanism, the output rotary member initially resists the rotary movement. The tensile force on the traction mechanism then causes a pivoting moment, which causes the output rotary member to pivot. If the output rotary member is pivoted, the first rotary member connected or coupled to the output rotary member pivots, in particular automatically. A toothing region, in particular an internal toothing, of the second rotary member and the circumferential region of the first rotary member having an external toothing, and thus the teeth of the first rotary member and the second rotary member, are brought into engagement by the pivoting movement.Upon further actuation or application of force to the traction means, a defined frictional force or frictional resistance is then overcome and the output rotary member and / or the first rotary member begin to rotate together with the second rotary member engaged therein.

[0017] The auxiliary drive device preferably comprises a housing configured to support or accommodate the output rotary member. The housing serving to support the output rotary member is pivotably mounted. In particular, the housing is pivoted together with the output rotary member. The housing and / or the output rotary member is rotatably or pivotably mounted about a pivot axis extending at a distance from a rotational axis of the drive rotary member. Preferably, the housing or a receiving space surrounding the output rotary member is adapted to a shape of the output rotary member.

[0018] A further exemplary embodiment is described below: When a tensile force is exerted on the traction means, in particular by the drive device, the output rotary member initially resists rotation due to frictional resistance. The output rotary member is designed such that pulling or actuating the traction means initiates the pivoting movement of the housing and / or the output rotary member until the first rotary member, which is coupled to the output rotary member, engages with the second rotary member. Actuating the traction means leads, in particular, to a pivoting moment for pivoting the housing and / or the output rotary member and / or the first rotary member.Since the housing and / or the driven rotary member cannot pivot any further when the first rotary member and the second rotary member are fully engaged, any further tension exerted on the traction mechanism is converted into an auxiliary drive rotary movement via the engagement of the traction mechanism with the driven rotary member. Since the first rotary member is engaged with the second rotary member in this position, its rotary movement is transmitted via the second rotary member to a main drive train of the main drive unit, thus providing auxiliary power to a building closure element.

[0019] An advantageous development provides that, to decouple the first rotary member and the second rotary member, the housing and / or the output rotary member is preferably preloaded in its rest position or idle position. At least one spring device can be provided for preloading. For example, the housing and / or the output rotary member and / or the first rotary member, in particular this unit, is preferably reset via compression springs, which in particular preload the unit, which is preferably formed from the housing and / or the output rotary member and / or the first rotary member, in its rest position. This allows the auxiliary drive device to be operated particularly easily and reliably.

[0020] Advantageously, the housing comprises two openings, with the traction mechanism being guided into the receiving device through one opening and out of the receiving device through the other opening. The openings are preferably channel-shaped. This provides the advantage that the traction mechanism is guided into the receiving device particularly easily and reliably.

[0021] An advantageous development provides that the first transmission device further comprises two deflecting rotary members, wherein the driving rotary member is coupled to the driven rotary member by means of the traction means via the two deflecting rotary members, which are configured to deflect the traction means. Preferably, the deflecting rotary members are each designed as a deflecting chain wheel. Particularly preferably, the two deflecting rotary members are designed identically or analogously. Preferably, the two deflecting rotary members are arranged between the driven rotary member and the driving rotary member. Particularly preferably, the deflecting rotary members are positioned or arranged such that they ensure that the traction means is guided into the housing or the receiving device and / or out of the housing or the receiving device. In particular, the deflecting rotary members are each assigned to an opening in the housing.Preferably, the respective deflecting rotary members are arranged above the respective opening in a vertical direction of the auxiliary drive device, which extends in particular perpendicular to a direction of rotation of the rotary members. In a respective rotational plane of the deflecting rotary members, the deflecting rotary members are arranged at a predetermined distance from one another.

[0022] Advantageously, the first transmission device is designed as a chain drive. In particular, the first stage of the two-stage transmission can be designed as a chain drive. Preferably, the drive rotary member forms a pinion or drive pinion of the chain drive. The "pinion" refers in particular to the smaller diameter of the two sprockets—drive rotary member and driven rotary member—in a chain transmission.

[0023] The auxiliary drive device preferably further comprises an auxiliary drive housing configured to accommodate the drive device, the first transmission device, and at least the first rotary member of the second transmission device. In other words, the auxiliary drive device can comprise a housing on which the drive device, the first transmission device, and at least the first rotary member are mounted. Particularly preferably, the DC motor, the chain drive, and the gear are mounted on the housing of the auxiliary drive device. This provides the advantage that the auxiliary drive device has a particularly stable construction.

[0024] A further advantageous embodiment provides that the auxiliary drive device comprises a switching device that can be switched by the pivoting movement of the housing and / or the output rotary member and / or the first rotary member for deactivating or maintaining the main drive unit in operation when the housing and / or the output rotary member and / or the first rotary member is deflected or pivoted from its rest position. The main drive unit is preferably designed as a motor, in particular as a 400 / 230 V AC three-phase / alternating current motor.

[0025] The auxiliary drive device or the auxiliary drive housing is preferably attached to the main drive unit with at least two fastening elements, which are particularly designed as screws. Particularly preferably, the housing of the auxiliary drive device, on which the DC motor, the chain drive, and the gear are mounted, is attached to the B-side of the drive motor by means of two screws. The auxiliary drive housing allows the auxiliary drive device to be attached to the main drive unit particularly easily and reliably.

[0026] Advantageously, the second rotary member is coupled to a shaft of the main drive unit, wherein the second rotary member is configured to transmit torque to the shaft. Particularly preferably, a torque from the auxiliary drive device is transmitted to the motor shaft of the drive motor via the internal gear, which is attached to the motor shaft. In particular, the second rotary member is assigned to a main drive train and / or connected thereto for common rotation. A subsequent worm gear transmission can result in a high overall transmission ratio, which enables low torques on the auxiliary drive device.

[0027] The advantages and preferred embodiments described for the auxiliary drive device of the drive system according to the invention also apply to the use of the auxiliary drive device according to the invention.

[0028] An exemplary embodiment is explained in more detail below with reference to the attached drawings. They show: Fig. 1 is a schematic representation of the auxiliary drive device in a side view; and Fig. 2 is a schematic representation of a main drive unit with the auxiliary drive device arranged on a B-shield in a plan view.

[0029] The embodiment explained below is a preferred embodiment of the invention. Fig. 1 shows a schematic representation of an auxiliary drive device 10 for the auxiliary driving of a building closure element that can be driven by means of a main drive unit 12. Fig. 2 shows a schematic representation of the main drive unit 12 with the auxiliary drive device 10 arranged thereon in a plan view. In connection with Fig. 1 and Fig. 2A structure of the auxiliary drive device 10, an arrangement of the auxiliary drive device 10 on the main drive unit 12 and a functioning of the auxiliary drive device 10 will be explained in more detail.

[0030] The main drive unit 12 is designed to drive a building closure element, such as a garage door, in particular a sectional door. The main drive unit 12 is designed as a drive motor. The main drive unit 12 is preferably designed as a 400 / 230 V AC three-phase / alternating current motor.

[0031] If, for example, a malfunction occurs, such as a power failure, the auxiliary drive device 10 is configured to drive the door, for example the garage door. The auxiliary drive device 10 is configured to move a building closure element from a closed position to an open position or to open it at least partially, i.e. completely or partially. In the open position, a passageway or entrance or exit of a building, for example a garage, is cleared. Furthermore, the auxiliary drive device 10 is configured to move the building closure element from an open position or at least partially open position to a closed position. In the closed position, the building closure element closes the passageway.

[0032] For this purpose, the auxiliary drive device 10 comprises a motor drive unit 14. The drive unit 14 is designed as a low-voltage direct current motor (e.g., 24 V DC). Furthermore, the auxiliary drive device 10 comprises a first transmission unit 16. The first transmission unit 16 forms a first stage or a single stage, in particular, of a two-stage transmission of the auxiliary drive device 10.

[0033] The first transmission device 16 comprises a drive rotary member 18. The drive rotary member 18 is designed as a drive pinion. Furthermore, the first transmission device 16 comprises an output rotary member 20. The output rotary member 20 is designed as a sprocket, in particular as a pivoting sprocket. A rotational axis D1 of the drive rotary member 18 or a center point of the drive rotary member 18 and a rotational axis D2 of the output rotary member 20 or a center point of the output rotary member 20 are arranged, in particular in a rest position, on a center line M which extends in a vertical direction of the auxiliary drive device 10, centrally through the auxiliary drive device 10. The vertical direction extends, in particular, perpendicular to a rotational axis and / or parallel to a rotational plane of the rotary members.

[0034] Furthermore, the first transmission device 16 comprises two deflecting rotary members, i.e., a first deflecting rotary member 22 and a second deflecting rotary member 24. The deflecting rotary members 22, 24 are arranged at a predetermined distance from one another. In particular, the deflecting rotary members 22, 24 are arranged next to one another parallel to a rotation plane of the two deflecting rotary members 22, 24. In particular, the deflecting rotary members 22, 24 are arranged at a predetermined distance from one another perpendicular to a rotation axis of the deflecting rotary members 22, 24—rotation axis D3 or center point of the first deflecting rotary member 22 and rotation axis D4 or center point of the second deflecting rotary member 24. The deflecting rotary members 22, 24 are each arranged to one side of the center line M.The first deflecting rotary member 22 is arranged at the same distance from the center line M as the second deflecting rotary member 24. Furthermore, the first deflecting rotary member 22 and the second deflecting rotary member 24 are designed identically or analogously to one another. The deflecting rotary members 22, 24 are arranged between the driving rotary member 18 and the driven rotary member 20, in particular in a vertical direction of the auxiliary drive device 10, which extends perpendicular to the axis of rotation of the rotary members. Perpendicular to the vertical direction of the auxiliary drive device 10 or the center line, the axis of rotation D1 of the driving rotary member 18 and the axis of rotation D2 of the driven rotary member 20 are arranged between the deflecting rotary members 22, 24, in particular on the center line M. The deflecting rotary members 22, 24—first deflecting rotary member 22 and second deflecting rotary member 24—are each designed as a deflecting sprocket.

[0035] The drive rotary member 18 and the output rotary member 20 and the deflecting rotary members 22, 24 are connected to one another via a traction mechanism 26. The drive rotary member 18, the first deflecting rotary member 22, the output rotary member 20, and the second deflecting rotary member 24 are arranged successively in a circumferential direction, in particular clockwise, and / or are coupled to the traction mechanism 26. The traction mechanism 26 is designed as a chain, in particular as a roller chain, particularly preferably as an endless chain. The traction mechanism 26 is thus placed around the drive rotary member 18, the first deflecting rotary member 22, the output rotary member 20, and the second deflecting rotary member 24. The teeth of the drive rotary member 18, the first deflecting rotary member 22, the output rotary member 20 and the second deflecting rotary member 24 engage with the traction means 26 and / or are coordinated with the traction means 26.

[0036] The drive device 14 is designed to drive, rotate, or move the drive rotary member 18. The drive rotary member 18 is coupled or connected to the drive device 14. In particular, the drive rotary member 18 is arranged on or at a shaft 28 of the drive device 14. If the shaft 28 of the drive device 14 rotates, the drive rotary member 18 also rotates, in particular automatically. In particular, torque or movement is transmitted from the drive device 14 to the drive rotary member 18. The traction means 26 is designed to transmit movement or torque to the output rotary member 20. If the drive rotary member 18 is rotated, the output rotary member 20 is set in motion, i.e. rotated.

[0037] The first transmission device 16 is designed as a chain drive or chain transmission. The drive rotary member 18 forms the drive gear, and the output rotary member 20 forms the output gear of the chain transmission. The chain transmission can also be referred to as a traction mechanism transmission or a positive-locking transmission. The traction mechanism 26, in particular the roller chain, is guided via the drive rotary member 18 and / or the deflecting rotary members 22, 24 and the output rotary member 20 and engages positively with the respective profile of the respective rotary member—drive rotary member 18, output rotary member 20, first deflecting rotary member 22, and second deflecting rotary member 24.

For example, the drive device is arranged on the receiving device 30 by means of four fastening elements B, in particular at one end region.

[0039] The auxiliary drive device 10 further comprises a housing 32, which is configured to receive or support the output rotary member 20. In other words, the output rotary member 20 is arranged in the housing 32. The housing 32, which serves to support the output rotary member 20, is pivotally mounted. In particular, the housing 32 is pivoted together with the output rotary member 20. The housing 32 and / or the output rotary member 20 is rotatably or pivotably mounted about a pivot axis D6 extending at a distance from the rotational axis D1 of the drive rotary member 18. Preferably, the housing 32 or a receiving space comprising the output rotary member 20 is adapted to a shape of the output rotary member 20. The housing 32 can be pivotally mounted by means of a suspension 38, for example by means of a pivot pin. In particular, the housing 32 is suspended.

[0040] The housing 32 further comprises two openings, i.e., a first opening 34 and a second opening 36. The openings 34, 36 are preferably identical. Furthermore, the openings 34, 36 are channel-shaped. The openings 34, 36 are designed to guide the traction means 26 into and / or out of the housing 32. In particular, the openings 34, 36 preferably form channel-shaped guides of the housing 32, via which the traction means 26 is guided into and / or out of the housing 32. The first opening 34 and the second opening 36 are arranged at a predetermined distance from one another in the circumferential direction. The openings 34, 36 are arranged on both sides of the center line M. If, in particular, a center line of the respective opening is extended to the center line M, the openings 34, 36 are arranged, in particular, in a V-shape or in a V-formation.The deflecting rotary members 22, 24 are positioned or arranged such that they ensure that the traction means 26 is guided into and / or out of the housing 32. In particular, the deflecting rotary members 22, 24 are each assigned to an opening 34, 36 of the housing 32. The first deflecting rotary member 22 is assigned to the first opening 34, and the second deflecting rotary member 24 is assigned to the second opening 36. The respective deflecting rotary members 22, 24 are preferably arranged above the respective opening 34, 36 in a vertical direction of the auxiliary drive device 10, which extends in particular perpendicular to a direction of rotation of the rotary members.

[0041] The output rotary member 20 is, in particular, annular in shape overall. The output rotary member 20 has external gearing 40. The drive rotary member 18 and the two deflecting rotary members 22, 24 are also annular and have external gearing.

[0042] Furthermore, the auxiliary drive device 10 comprises a second transmission device 42. The second transmission device 42 forms, in particular, a second stage of the, in particular, 2-stage transmission of the auxiliary drive device 10. The second transmission device 42 comprises a first rotary member 44 and a second rotary member 46. The first rotary member 44 is designed as a gear. The first rotary member 44 has external teeth.

The output rotary member 20 is, in particular in diameter, larger than the first rotary member 44. The output rotary member 20, in particular a radius or diameter of the output rotary member 20, is larger than the first rotary member 44, in particular a radius or diameter of the first rotary member 44. The output rotary member 20 comprises the first rotary member 44 in at least one area or section of the first rotary member 44. In particular, the output rotary member 20, as in particular Fig. 2can be seen, is arranged at an end region E of the first rotary member 44. The output rotary member 20 rests against a circumferential surface or lateral surface or outer surface of the first rotary member 44. For example, the output rotary member 20 can be arranged on a hub of the first rotary member 44. An axis of rotation D5 or central axis of the first rotary member 44 coincides with the axis of rotation D2 of the output rotary member 20. The axis of rotation D5 is offset or arranged at a predetermined distance from the axis of rotation 60 of the main drive unit 12.

[0043] The output rotary member 20 and the first rotary member 44 are pivotally mounted together. Therefore, if the housing 32 and / or the output rotary member 20 are pivoted, the first rotary member 44 pivots along with them.

[0044] The second transmission device 42 further comprises the second rotary member 46. The second rotary member 46 is designed as a gear. Furthermore, the second rotary member 46 is designed as an internal gear or ring gear. In particular, the second rotary member 46 has internal teeth. The first rotary member 44 and the second rotary member 46 together form, in particular, a gear pair. The second rotary member 46 is, in particular, annular in design, in particular overall. A toothing 50, in particular an internal toothing, is formed on an inner wall 48 of the second rotary member 46. The first rotary member 44 is arranged in a space 52 surrounded by the second rotary member 46 and its toothing 50. The teeth of the toothing 50 of the second rotary member 46 are distributed over the circumference or arranged at equal distances from one another in a circumferential direction of the second rotary member 46. The teeth of the toothing 50 are triangular in cross-section.

[0045] The second rotary member 46 is arranged at an end region or end of the first rotary member 44 opposite the end region E. Preferably, the first rotary member 44 can have a toothing or the toothing region in a main extension direction or a direction of the rotational axis D5 of the first rotary member 44 over its entire length or only in the end region opposite the end region E, i.e., in particular, not over its entire length.

[0046] The toothing 50 of the second rotary member 46 has spaced-apart teeth with a triangular cross-section that are regularly distributed around the circumference. The teeth extend at least partially, i.e., completely or partially, in the axial direction over the entire toothing region forming the toothing 50. The first rotary member 44 has external toothing. The external toothing of the first rotary member 44 is designed to correspond, in particular, to the toothing 50 of the second rotary member 46. The external toothing of the first rotary member 44 extends at least partially, i.e., completely or partially, in the axial direction over the entire external toothing region. The external toothing region of the first rotary member 44 can have axially extending rib-like teeth, in particular with a triangular cross-section, and spacings therebetween. Furthermore, the second rotary member 46 is designed to be larger, in particular in diameter, than the first rotary member 44.

[0047] Fig. 2 shows a drive system 54 for driving a building closure element (not shown in the figures). The drive system 54 comprises the auxiliary drive device 10 and the main drive unit 12. The auxiliary drive device 10 is arranged or attached to the main drive unit 12. The auxiliary drive device 10 comprises an auxiliary drive housing 56. The auxiliary drive housing 56, on which the drive device 14, the first transmission device 16, and / or the first rotary member 42 or the second rotary member 44 are mounted, is fastened to a B-side 58 of the main drive unit 12 by means of fastening elements, for example, by means of two screws. The term "B-side" refers in particular to the B-shield or the B-end shield of the main drive unit 12.

[0048] The second rotary member 46 of the second transmission device 42 is connected or coupled to a shaft of the main drive unit 12. In other words, the second rotary member 44 is attached to the shaft of the main drive unit 12. In particular, the second rotary member 46 can be connected for joint rotation with the shaft connected to a main drive train of the main drive unit 12.

[0049] The function of the auxiliary drive device 10 will be discussed in more detail below. In the rest position, the drive rotary member 18 is not moved by the drive device 14, i.e., the drive rotary member 18 does not rotate. In the rest position, no movement is transmitted to the output rotary member 20. In the rest position, none of the rotary members move.

[0050] If the drive device 14 is actuated, the drive device 14 actuates, moves, or rotates the drive rotary member 18. The auxiliary drive device and / or the drive device can be controlled or operated, for example, by a controller, in particular an air supply controller. This actuates the traction means 26. If the traction means 26 is actuated by the drive device 14 or a force is exerted on the traction means, the output rotary member 20 initially resists the rotational movement due to a frictional force exerted on the output rotary member 20. The tensile force on the traction means 26 then initially causes a pivoting moment that causes the output rotary member 20 and / or the housing 32 to pivot. As a result of the pivoting of the output rotary member 20, the first rotary member 44 is pivoted simultaneously.The toothed area 50 of the second rotary member and the toothed area of ​​the first rotary member 44, and thus the teeth of the first rotary member 44 and the second rotary member 46, are brought into engagement by the pivoting movement. By further actuating the traction means 26, the frictional force, in particular a defined or predetermined one, is then overcome, and the tapping rotary member 20 and the first rotary member begin to rotate together with the second rotary member 46 engaged therein.

[0051] By pivoting the output rotary member 20 and the first rotary member 44 coupled thereto, the first rotary member 44 and the second rotary member 46 can be brought into engagement. The tooth flanks of the teeth of the first rotary member 44 and the second rotary member 46 are inclined such that, when engaged, they are configured to correspond to one another in a tangential contact area. Bidirectional pivoting is possible.

[0052] Since the first rotary member 44 is engaged with the second rotary member 46 in this position, particularly outside the rest position or inoperative position, its rotational movement is transmitted via the second rotary member 46 to the main drive train or the shaft of the main drive unit 12, thus auxiliary driving a building closure or building closure element. Thus, by a simple actuation, namely by actuating the traction means 26, particularly with the aid of the drive device 14, the auxiliary drive device 10 can be simultaneously engaged and rotated without any further steps.

[0053] Overall, a cost-effective and space-saving solution for industrial door drives with 400 / 230 V AC three-phase / alternating current motors is proposed, which can be operated with the AC72. In particular, a power-operated and / or battery-buffered auxiliary drive device with a 24 V DC motor for driving a building closure is described. "Battery-buffered" specifically means that power can be drawn from a battery or accumulator, especially independently.

[0054] For this purpose, an auxiliary drive with a 24 V DC motor is mounted on the 400 / 500 series drive motor in place of an emergency hand chain device. The auxiliary drive is preferably a separate unit consisting of a 24 V DC motor and a 2-stage gearbox. The 1st stage is a chain drive and the 2nd stage is a gear pair. The housing of the auxiliary drive, on which the DC motor, the chain drive and the gear, in particular the first rotating link, are mounted, is fastened to the B-side of the drive motor by means of two screws. The torque of the auxiliary drive is transmitted to the motor shaft of the drive motor via the internal gear, which is fastened in particular to the motor shaft. A subsequent worm gear transmission results in a high overall transmission ratio that enables low torques at the auxiliary drive.

[0055] The auxiliary drive device can be mounted at a location on an emergency hand chain device on the B-side of the drive motor, i.e., the main drive unit, for example, the 400 / 500 Series from Hörmann KG. Furthermore, the auxiliary drive device can be operated with a control unit, in particular an AC72 air supply control unit. The goal of a control unit or air supply control unit can be to draw power independently of an intact battery system. To this end, the control unit monitors the power quality in the supply network, particularly at predetermined intervals. If a fault is detected by a control unit, for example, the drives can be temporarily powered by a battery and / or accumulator. List of reference symbols:
