The disclosure relates to a direct swing leaf actuator, i.e. an actuator designed to be connected via its driven shaft directly, i.e. without an intermediate connection of a linkage, to a swivel axis of a swing leaf in a swiveling manner thereto. Such actuators are generally sunken in a floor or inserted into a ceiling or a lintel and are capable of opening and/or closing the connected swing leaf. Known examples of such an actuator are floor door actuators and floor door drives. Door leaves and window leaves are for example considered as swing leaves.
A disadvantage of such actuators is that they have to be aligned such that the rotational axis of their respective driven shaft must be virtually identical to the swivel axis of the swing leaf to be actuated and after assembling the swing leaf, it must securely enter into rotational engagement with the driven shaft of the actuator. The smallest deviations can mean that the driven shaft can tilt when the swing leaf is actuated with its drive element to be rotated. Additionally, unevenness of the floor can mean that the cement box receiving the floor leaf actuator is not mounted at the required depth and/or inclination in the floor. This can mean that the driven shaft is spaced apart from the swing leaf such that the actuator is incapable of swiveling the swing leaf. Floor door actuators are for example built into a cement box formed into the floor. The recess in the floor to receive the cement box must be made before the actuator and the swing leaf are assembled and namely precisely in each case. This requires very precise planning and design of the floor work to receive the cement box.
For example, DE 39 23 639 A1 discloses a direct swing leaf actuator, i.e. an actuator designed to be connected via its driven shaft directly, i.e. without an intermediate connection of a linkage, to a swivel axis of a swing leaf in a swiveling manner thereto. Such actuators are generally sunken in a floor or inserted into a ceiling and are capable of opening and/or closing the connected swing leaf. Disadvantageously, the entire actuator unit must be moved when the driven shaft is finely adjusted and it cannot be replaced, without disassembling the door leaf.
EP 2 754 827 A2 discloses a direct swing leaf actuator for actuating a swing leaf of a leaf system, comprising a receiving box for arrangement in or on a stationary part of the leaf system or of a building comprising the leaf system, and comprising a driven shaft, which interacts with an actuator unit, wherein a swing leaf can be placed on the driven shaft in a torque-transferring manner, and wherein a device is present for adjusting the spatial position of the driven shaft relative to the receiving box. After placing a swing leaf on the driven shaft, the bearing of the driven shaft can no longer be changed in the vertical position and in the planar side position, which can make the assembly and the fine adjustment of the direct swing leaf actuator complex.
The present disclosure therefore makes it possible to simplify the assembly and fine adjustment of the swing leaf relative to the idle part, for example of a door system with a direct swing leaf actuator.
This is achieved by proceeding from a direct swing leaf actuator according to the preamble of the claims in conjunction with the characterizing features.
Advantageous further developments of the disclosure are indicated in the dependent claims.
The disclosure includes the technical teaching that a direct swing leaf actuator for actuating a swing leaf, i.e. for example of a swing leaf of a door system, has a receiving box for arrangement in or on a stationary part of the leaf system or of a building comprising the leaf system, for example the wall, the ceiling or in particular the floor. Furthermore, the direct swing leaf actuator has a driven shaft, which interacts with an actuator unit of the direct swing leaf actuator. The actuator unit corresponds in function to a classic direct swing leaf actuator, only without housing or receiving box. In this case, a swing leaf is designed so that it can be placed on the driven shaft in a torque-transmitting manner. Additionally, a device is present for adjusting the spatial position of the driven shaft relative to the receiving box.
According to the disclosure, this device has an adjusting frame with a height-adjusting unit, which is designed as a receiving module and is therefore separable. The adjusting frame is arranged separably in the receiving box and in particular individually next to or following an actuator unit, wherein the latter, as well as the receiving module, is also replaceable and for example forms only one closer with a spring force storage means or is designed as a complete motor-driven door actuator.
The driven shaft is received by means of the height-adjusting unit on the adjusting frame so as to be movable towards and away from the swing leaf along its rotational axis such that the driven shaft and therefore also the swing leaf can be height-adjusted, while the swing leaf is already assembled. This makes it possible to adjust the driven shaft after inserting the direct swing leaf actuator for example in a floor such that, in the case of the assembled swing leaf, it securely enters into rotational engagement therewith, which simplifies the assembly. Additionally, the assembly of the swing leaf actuator according to the disclosure can take place less precisely than in the state of the art since the adjusting frame according to the disclosure can itself be adjusted and therefore finely adjusted even with a swing leaf assembled on the driven shaft.
Moreover, the arrangement without actuator unit can be pre-assembled. Irrespective of this, a very small rear axle dimension of preferably 38 mm to 48 mm can be implemented, which simplifies the assembly further.
The actuator unit is preferably arranged substantially or completely outside of the adjusting frame and structurally separated or structurally separable therefrom. Therefore, the adjusting frame and the actuator unit form separate modules and can thus be assembled in the receiving box independently of one another. This allows a conventional direct swing leaf actuator to also be used as the actuator unit and the drive can be replaced in the case of an already assembled swing leaf. Thus, for example a spring force storage means can even subsequently be replaced with a motor-driven swivel drive.
Alternatively or additionally, a gear wheel or a chain wheel can be arranged on the driven shaft which interacts with the actuator unit. That is to say that the actuator unit, which generates the force to swivel the swing leaf, can be arranged spatially separated from the driven shaft. This makes it possible to be able to adjust the driven shaft not only in or along its rotational axis, but also in a planar plane transversely to its rotational axis in order to compensate for assembly inaccuracies in relation to the swing leaf. The swing leaf drive can thereby be received displaceably in the receiving box such that it can follow a displacement of the adjusting frame or the swing leaf drive can also, if required, be subsequently adjusted after adjusting the adjusting frame.
A gear wheel is preferably provided and, according to a further configuration of the disclosure, encloses the driven shaft and is operatively connected to the driven shaft by means of a longitudinal toothing in a torque-transmitting manner such that the driven shaft is displaceable along its shaft axis or along its rotational axis, while the gear wheel remains in its vertical position. Therefore, a secure operative connection between driven shaft and actuator unit is ensured which increases the operational safety and makes the adjustability constructively simple.
In the case of each embodiment of the aforementioned actuators, the height-adjusting unit can have an adjusting element, in particular an adjusting screw, which is arranged in or on the adjusting frame such that, in the case of a swing leaf placed on the driven shaft, the adjusting screw is not hidden thereby and can be actuated by a person. This makes it possible to easily adjust the vertical position of the driven shaft and therefore of the assembled swing leaf.
The adjusting element, in particular the adjusting screw, can preferably be actuated from an upper side of the direct swing leaf actuator, from which the driven shaft also protrudes. The upper side is in this respect the side, which faces the swing leaf and which is arranged pointing upwards from the receiving box in the case of a design of the direct swing leaf actuator as a floor door actuator. This makes it possible to adjust the vertical position for example by means of a screwdriver.
Moreover, the height-adjusting unit can have a swing arm.
The swing arm is preferably rotatably received on a first end side in a pivot point on the adjusting frame and articulated on a second end side in an articulation point so as to be adjustable in the vertical direction by the adjusting element, in particular the adjusting screw. The swing-arm solution enables a simple construction whilst maintaining the necessary stability in order to introduce the force of the actuator unit into the swing leaf in an operationally safe manner. The driven shaft is thereby mounted on or in the swing arm of the height-adjusting unit, in particular in a region between the pivot point and the articulation point so as to absorb vertical forces and/or rotatably in a shaft axis of the driven shaft.
It can be provided that a bearing cup is received on the swing arm in which the driven shaft is mounted with a rear shaft end. This shaft end is opposite the shaft end on which the swing leaf can be placed. This creates a constructively simple arrangement and the driven shaft can remain vertical in spite of adjusting the inclination of the swing arm and can shift up and down in or on the adjusting frame depending on the adjustment.
Preferably on the bottom, i.e. on the side facing away from the swing leaf, is arranged a support sleeve in the adjusting frame, into which the bearing cup partially protrudes in order to maintain the vertical of the driven shaft. The adjusting frame thus forms the supports for the driven shaft which benefits the stability.
Preferably, at the top of the adjusting frame, a radial bearing is introduced in which the driven shaft is at least indirectly received. Therefore, the driven shaft is rotatably received on the adjusting frame. This also allows the forces to be passed from the adjusting frame to the receiving box; and the actuator unit, i.e. the drive or the spring force storage means itself, remains free of forces, which act on the driven shaft.
Alternatively or additionally, the adjusting frame is fastened, in particular screwed, on the receiving box by means of fastening elements, in particular screw elements. To this end, the adjusting frame has openings which are larger than a shaft of the fastening elements, in particular screw elements, in order to change a planar position of the adjusting frame in the plane of the bottom of the receiving box. Thus, only the adjusting frame is constructively adapted for adjusting; the receiving box can be designed conventionally and the actuator unit, i.e. the drive or the spring force storage means, does not have to be adjusted or at best tracked.
According to a further embodiment, the adjusting frame has eccentric elements. The eccentric elements form at least indirectly an operative connection between the adjusting frame and the receiving box in order to change a planar position of the adjusting frame in the plane of the bottom of the receiving box when the eccentric elements are actuated. Eccentric elements have the advantage that fastening elements, such as screws, do not have to be loosened beforehand for the adjustment; it is sufficient to simply rotate the respective eccentric element.
The adjusting frame preferably has a box shape with edge lengths, which deviate from one another by a maximum of 70%, preferably a maximum of 50% and particularly preferably a maximum of 30%. These are particularly well-suited measurements for example for use in floors.
Alternatively or additionally, the actuator unit, i.e. the drive or the spring force storage means, can be fastened in the receiving box by means of a receiving element. The arrangement of the receiving element in the receiving box is thereby designed to be movable such that the actuator unit can be fastened so as to be variably movable towards and away from the driven shaft along a longitudinal direction. This enables the actuator unit to also be adjusted in the receiving box, without having to design the actuator unit a particular way, precisely when the adjusting frame is displaced with the driven shaft in its planar plane. This increases the versatility in regards to the actuator units that can be used, for example in the form of a classic floor door actuator.
Further measures that improve the disclosure will be outlined in greater detail below together with the description of a preferred exemplary embodiment of the disclosure on the basis of the figures. They show:
The floor door actuator 100 comprises a transparently illustrated receiving box 10 in the form of a cement box designed in a substantially known manner. The receiving box 10 comprises in the interior a receiving element 28 which is designed as a holding profile only for the actuator unit 12. The receiving box 10 is sealed on its upper side facing the swing leaf by a cover preferably comprising two cover parts 35a, 35b. The receiving element 28 receives the actuator unit 12 in the form of a conventionally designed floor door closer in a stationary manner and so as to be individually replaceable. The receiving element 28 comprises elongated holes 28a, via which the actuator unit 12 is longitudinally displaceable with the receiving element 28 in the longitudinal direction of the receiving box 10 and can be fixed in the respective assembly position in the receiving box 10 via screw elements 26.
A height-adjusting unit 15 is connected to the left, rear end of the actuator unit 12 shown and is also received in the receiving box 10. A driven shaft 11 in the height-adjusting unit 15 protrudes from the cover 35a, 35b and is designed to be connected in a rotationally-operative manner to a swing leaf in its swivel axis. The configuration of the driven shaft 11 in this region preferably corresponds to the configuration of a driven shaft of a conventional floor door actuator or floor door drive and is therefore not described further.
The actuator unit 12 preferably also has a driven shaft 12a, which is also fully received in the receiving box 10. The driven shafts 11, 12a are connected to one another in a rotationally-operative manner. In the example shown, this operative connection is implemented by a gear wheel 12b being arranged in a torque-proof manner on the driven shaft 12a, said gear wheel 12b meshing with a gear wheel 16, which is arranged in a torque-proof manner on the driven shaft 11. Therefore, it is possible for the actuator unit 12 to swivel the indicated swing leaf via the height-adjusting unit 15. Additionally, the step-up or step-down gear ratio can be changed by different gear wheel pairs between the output shaft, the drive unit and the rotational axis of the door leaf. This enables, for example in the case of existing drive units with cam technology, an increase of the door opening angle and/or generally flexible, needs-based drive assembly, even as part of a retrofit.
The height-adjusting unit 15 and the actuator unit 12 are arranged independently of one another in the receiving box 10 and the connection between these two structural units is preferably limited to the operative connection between the two gear wheels 12b and 16. Of course, the height-adjusting unit 15 and the actuator unit 12 can, however, also be connected to one another in other ways.
In the cover part 35b, a through-opening 35c is designed, whose function will be explained further below.
The through-opening 35c not designated here is sealed by means of a covering 36, for example made of rubber, preferably in a moisture- and dust-proof manner. When the covering 36 is removed, an adjusting screw 17 of the height-adjusting unit 15, which will be explained further below, is accessible from above.
The vertical direction Z thereby designates the direction along a longitudinal extension or rotational or shaft axis 11a of the driven shaft 11 towards or away from the swing leaf not illustrated. The reference numeral 18 designates the upper side of the adjusting device 13 facing the swing leaf. The driven shaft 11 is freely rotatably received by means of a radial bearing 25 in a wall 14a of the adjusting frame 14 facing the swing leaf and in a support sleeve 24, which is designed on a wall 14b of the adjusting frame 14 facing away from the swing leaf and protrudes in a direction of the swing leaf from the wall 14b.
In the walls 14a, 14b, openings 27 are present, which align with one another in pairs in the Z direction and enable a lateral displacement of the adjusting device 13, explained further below, i.e. transversely to the Z direction.
The adjusting screw 17 is guided through a through-opening 14c of the wall 14a or can be operated through it using a tool and the adjusting screw 17 is supported on the lower wall 14b in a rotatably mounted manner. The adjusting screw 17 is provided at least in a region between the wall 14a and a receiving portion 33 with an external thread. The receiving portion 33 is attached to the lower wall 14b on the inside of the adjusting frame 14. The adjusting screw 17 is received stationarily in the receiving portion 33 in the Z direction and freely rotatably along its longitudinal extension such that its rotational axis extends in the Z direction.
The adjusting screw 17 has on its end facing the through-opening 35c (see
The external thread of the adjusting screw 17 is screwed into a corresponding internal thread of a screw-in element 31 and/or a sleeve 32 attached thereto or formed thereon. Owing to the stationary reception in the receiving portion 33, it is possible to displace the adjusting arrangement of screw-in element 31 and sleeve 32 in the vertical direction Z by rotating the adjusting screw 17. This changes the distance of the adjusting arrangement 31, 32 from the wall 14a or 14b.
When further considering
As shown in detail in
The driven shaft 11 has roughly centrally a longitudinal toothing 23 extending in the Z direction, which is engaged with a corresponding inner toothing 39 of the gear wheel 16 in a torque-transmitting manner and displaceably in the Z direction.
The driver 30 can be designed in one piece with the driven shaft 11 or, as shown here, positively engage into a corresponding upper receiving portion of the driven shaft 11. The driver 30 has on its upper end facing away from the driven shaft 11 an engagement section designed in a known manner for the swing leaf to be placed thereon.
The gear wheel 16 has on its end facing the adjusting frame 14 a bearing section 34, which is inserted into the radial bearing 25, via which the gear wheel 16 is freely rotatably mounted in the adjusting frame 14.
If the adjusting screw 17 is turned for example clockwise, owing to the engagement of the external thread of the adjusting screw 17 with the sleeve 32 or with the screw-in element 31, the latter is moved in the Z direction towards the upper wall 14a. Owing to the stationary mounting of the swing arm 19 on the right end, the middle pins 38 and the bearing cup 22 supported by them are therefore also moved in the same direction as the screw-in element 32. Owing to the bearing ball 29, the driven shaft 11 and the driver 30 are therefore also moved in this direction.
Advantageously, the openings 27 are, in at least one of the two horizontal directions, i.e. in the X direction (=longitudinal direction) and/or Y direction (=transverse direction—see
This makes it possible to displace the adjusting frame in the X direction and/or Y direction and therefore to also align the driven shaft 11 in the plane transverse to the Z direction and namely preferably in the range of 10 mm.
In
As a result, three-dimensional adjustability of the driven shaft 11 in relation to the receiving box 10 is created in the maximum case.
The design of the disclosure is not restricted to the preferred exemplary embodiment indicated above. In fact, a number of variants is conceivable which make use of the illustrated solution even with fundamentally different designs. All features and/or advantages emerging from the claims, the description or the drawings, including constructive details or spatial arrangements, may be essential to the disclosure even in the most varied combinations. The floor door actuator 100 can be designed as a floor door drive, which can thus move the connected swing leaf in both swivel directions (open and closed). Alternatively or additionally, the swing leaf can be formed by means of a window or door leaf. Alternatively or additionally, instead of being accommodated in the floor, accommodation in the ceiling is in turn also provided. In this case, a mount must be provided between the driven shaft 11 and the bearing cup 22 which prevents movement of the driven shaft 11 in the Z direction in relation to the bearing cup 22. Instead of being accommodated in the ceiling, assembly on a frame, which freely rotatably receives the swing leaf, can also be provided. The function of the receiving box 10 would then be assumed by a housing attached to the frame, which receives the swing leaf actuator 12 and the adjusting device 13. Instead of the gear wheels 12a, 16, any other type of gear, such as for example a chain drive, can be used.
In summary, the floor door actuator 100 according to the disclosure enables small dimensions with very good adjustability even with an assembled swing leaf and good ability to replace the drive. Door closers or -drives already present can be integrated. Double-leaf door systems with small door leaf widths are possible. The thus formed swing leaf actuator is very low-maintenance. An in particular mechanical closing sequence control can be readily implemented.
