Description

The invention relates to a securing and / or actuating device for a door, a window or the like.

Recently, doors, especially front doors, are being increasingly equipped with electromechanical actuators for the closing elements in connection with modern access control systems, such as those with biometric proof of identity. All drives have in common that a relatively large mechanical force must be generated in order to move a closing element quickly from one layer to another position. The force required for this purpose acts either linearly or in the form of a torque. In a linear movement, for example, a push rod is moved, which in turn actuates one or more closing traps. By applying a torque, for example, a pawl is actuated or rotatably mounted traps are retracted and extended. These known drives operate with one or more electric motors and usually complex gears, which realize the power transmission from the electric motor to the closing element. Such motor driven systems are constructed comparatively expensive.

An object of the present invention is to provide a simply constructed securing and / or actuating device.

This object is achieved by a securing and / or actuating device according to claim 1. Thereafter, a drive is used with a transmission element. The transmission element comprises a torsion element. In this case, a linear or rotary movement of the transmission element is based at least partially on a shortening of the torsion element. The shortening of the torsion element is caused by a twisting of the torsion element. The twisting of the torsion element is due to a transmission of the rotational movement of the shaft to the torsion element. Advantageous embodiments of the invention are specified in the subclaims.

A basic idea of the invention is the use of a drive with a torsion element. The invention takes advantage of the fact that a torsion leads to a shortening of the torsion element. By simply twisting the torsion element, this shortens by the distance required for operating a fuse and / or actuator. The proposed solution can thus be realized in a simple and robust manner, a typical movement for triggering a fuse and / or actuator. The typical motion is characterized by being fast, preferably in a time of one second, to cover a short distance, typically about 20 millimeters, and a relatively large force, typically about 50 to 200 Newton, when moving. is transmitted to the fuse and / or actuator. In summary, with the invention in a particularly simple manner a component can be moved in a short time with great force. In this context, it is also advantageous that the drive according to the invention can be designed so that any fluctuating mechanical resistances, as they can occur in an actuator, for example, by a warped door or a security device, for example, by a not-serviced lock or closing fitting reliably be overcome. Compared with other solutions, the invention is also characterized by the fact that no sophisticated and expensive transmission is needed. As a result, the space required is small and there are new installation and thus also possible applications.

A typical application of the present invention is the operation of a multi-point lock in a house entrance or exterior door, in particular in a lock in which a plurality of latch bolts lock the closed door next to a central lock and unlocked by means of an electric motor drive to open. In such a locking solution finds a self-locking, d. H. an automatic triggering of the additional locks instead. To open the motor drive transferred at a corresponding control signal, the locks from the locking position to the unlocked position. In other words, it unlocks by pulling back the latch bolts. This is usually done by means of a push rod which is moved by a drive according to the invention. In this case, a linear movement of the push rod takes place. With the aid of the present invention, a pressure force can be exerted on the securing and / or actuating element. With appropriate design, for example, a deflection, a tensile force can be exercised for differently constructed multiple locks. When using two electric motors and two torsion elements, both a compressive force and a tensile force can be provided if required.

Due to its design, the twist drive can only provide power in one direction. Nevertheless, the invention is not only suitable for linear movements of safety and / or actuators, but also for rotational movements. So it is possible, for example by deflecting the train, a rotation of the fuse and / or To reach actuator. The transmission element can then be designed to execute a rotational movement.

The present invention is particularly suitable for security devices for doors, windows or the like. Locking devices are understood to mean in particular locking systems (locks). This includes in particular engine locks, so locks in which the opening and closing is motorized, so that a fully motorized locking takes place, but also automatic locks with motor opening, so locks in which the closing is done automatically, the opening, however, driven by a motor. Particularly advantageous is the application of the invention in locks with multiple locking.

However, the present invention is not only suitable for security devices, but also for actuator for doors, windows or the like. Actuators are understood to mean in particular devices for opening and closing windows and doors, u. a. Door closers, and devices for tilting, lifting, sliding, folding, turning and swinging of windows and doors, in particular with the aid of fittings (fittings). This includes u. a. Turning, tilting and turning / tilting fittings, in particular window fittings, but also sliding fittings for moving windows vertically or horizontally into an open position.

In this case, a safety and / or actuating element is understood to be the element that performs the actual function of the safety and / or actuating device, in particular a closing element or a fitting. Hereinafter, the terms fuse element, actuator, closing element (closing fitting) and fitting partially synonymous used. Simplified could also be generally spoken of an actuator, as far as an element is understood with which not only an opening or closing a door, a window or the like is possible, but with which a lock can be operated.

The present invention is particularly advantageous for use in regularly operated and / or to be closed objects, especially in doors and windows in buildings, where the space available for the drive space is narrow, but (almost) arbitrarily long. Due to the torsion element involved in the inventive solution, which is usually an elongated structural element, the solution according to the invention is suitable with its arranged in a narrow, elongated housing drive especially for installation situations with one in a spatial direction, in the However, two other spatial directions limited space. In the preferred field of use for securing and / or operating doors, windows or the like, the assembly is preferably carried out in the interior of the door leaf, in particular under the fitting on the lock side of the door or in the interior of the window frame. However, an assembly of the drive and the fitting in or on the window sash or in or on the door frame is also possible. The place of assembly, ie door leaf or door frame or window sash or window frame, is usually made of solid wood, plastic or metal profiles.

The torsion element may, for example, be a fundamentally rigid, self-supporting element, such as a rod, a beam or the like. However, the use of a flexible, non-rigid element, in particular one or more fibers, has proved to be advantageous for transmitting the rotational movement of the shaft to the torsion element. It is particularly advantageous in this case if the torsion element comprises a multicore cord, a rope bundle, a number of bands or the like and the shortening of the torsion element is caused by a twisting of these components, ie a twisting together or a helical winding around one another. With the aid of such a twisting drive, a particularly efficient and, in addition, particularly elastic power transmission can be realized. In contrast to conventional solutions with gear drives, which are relatively inelastic, peak loads can be minimized with the twist drive according to the invention. The twisting drive is very elastic, especially at the beginning of the movement. The engine can start almost free. At the end of the movement, when the torsion element is twisted, there is still some residual elasticity. Load peaks can therefore be reduced, whereby the motors used are less stressed and increases their life.

Locking and / or operating devices for doors and windows are subject to particularly great price pressure. Therefore, the conventional gear used there are not only expensive, inelastic and require a lot of space, but also loud because of the use of inexpensive gear transmission. With the present drive, however, a comparatively quiet and therefore inconspicuous actuation of the fitting can take place. The particularly low volume makes the use of the invention particularly in the operation of windows, for example in an automatic opening and closing of windows, interesting.

For twisting a comparatively low torque is required. In other words, due to the principle of operation with small electric motors of low power and with low torques on the motor shaft comparatively high tensile forces can be generated. Therefore, the power consumption of the participating electric motors is low and with the help of a suitable buffer device, the power supply of the drive can be ensured even with a voltage drop for a long time.

As torsion elements are preferably fibers. A fiber is understood to be a thin and flexible structure in relation to the length. The fibers are preferably made of suitable plastic materials, such as polymers such as polyamide or polyethylene, known under the trade name Dyneema ^® . Other suitable materials include steel and carbon fibers.

For twisting fibers are particularly suitable with a small diameter and long length. The longer the fiber is and the smaller the diameter of the fiber, the less torque the electric motor used needs. Depending on the desired elasticity, the fibers may also be braided.

If the torsion element is arranged at least partially in a casing, it is not only protected against mechanical and other disturbing influences that impair the function under certain circumstances. The torsion element can, assuming sufficient flexibility, are also not rectilinear, so that even in shorter installation spaces, the desired length of the torsion element can be accommodated.

Various embodiments of the drive are possible. Thus, the drive may comprise more than one electric motor and / or several drives are provided. Further embodiments of the invention result, for example, in that the safety and / or actuating device according to the invention can have a plurality of motor-driven securing and / or actuating elements, wherein each safety and / or actuating element can be assigned one or more drives. It is also possible that a single drive several fuse and / or actuating elements simultaneously or sequentially drives. Further embodiments of the invention result from the fact that the transmission element may comprise more than one torsion element. In this case, for example, the shaft of an electric motor is operatively connected to at least two torsion elements such that the at least two torsion elements are simultaneously rotated. Alternatively, the drive comprises two electric motors whose shafts are each operatively connected to a torsion element such that the torsion elements are not simultaneously rotated. Further embodiments of the invention are obtained when two or more torsion elements are in operative connection with exactly one securing and / or actuating element. Further embodiments result from the fact that the torsion element itself is the transmission element. Then, the torsion element connects the electric motor, more precisely the rotatable shaft of the electric motor with the securing and / or actuating element. Or the torsion element is only a part of the transmission element and cooperates with other parts of the transmission element, for example a push rod, a plunger, a roller or the like.

Of particular advantage is also a variant of a safety and / or actuating device, in which a motor control of the electric motor is designed such that the movement of the transmission element by the electric motor, in particular the manner of movement of the transmission element, from a previous movement of the fuse - And / or actuating element, in particular on the manner of movement of the securing and / or actuating element, is dependent. For example, the time course and the size of the torque transmitted to the transmission element can be made dependent on whether and how the safety and / or actuating element is previously moved manually. As a result, a kind of servo drive for motor support of backup and / or actuators can be realized in a particularly simple manner.

It is clear to the person skilled in the art how the described embodiments can be combined with one another in order to use the invention for a variety of applications. The skilled person is also clear that beyond the described embodiments, there are other embodiments that take up the basic idea of the present invention and how they can be implemented in a concrete constructive solution.

All figures show the invention not to scale, while only schematically and only with their essential components. The same reference numerals correspond to elements of the same or comparable function.

Below is a locking system 1 described with a multi-point lock. In 1A is merely exemplified a multiple locking system with a known and widely used fitting, in which the present invention can be used.

The locking system 1 includes, as in 1A pictured, a central castle 2 and two self-locking additional locks 3 , The central castle 2 has a latch 4 and a central latch 5 on. The locking elements 6 the additional locks 3 are designed as a latch bolt and move independently from an unlocked position into a locking position when the door leaf 7 gets into the closed position. The additional locks 3 and the central latch 5 are by a continuous movable push rod 8th operable, with moving the push rod 8th in the direction of actuation 9 and thus the unlocking of the additional locks 3 with the help of an electromechanical drive 10 he follows. The drive 10 is with the central castle 2 over the push rod 8th and an electrical connection line 11 connected.

In 1B shown is a modified embodiment, in which no continuous push rod 8th is used. Instead, for each additional lock 3 a separate electromechanical drive 10 intended. Another electromechanical drive (not shown) for the central lock 2 may also be provided. Advantageously, in this case, all drives or their controls are electrically connected instead of mechanically.

The basic principles of the present invention will be described with reference to the in 2 Illustrated embodiment illustrated and are correspondingly applicable to the illustrated in the other figures embodiments.

At the drives 10 are twist drives. Every drive 10 is in a housing 14 accommodated, which consists for example of extruded aluminum profile with a plastic cover. The drive housing 14 are inside the door leaf 7 attached and from the fitting side 15 of the door leaf 7 out with fixing screws 16 fixed.

The in the drive housing 14 placed twist drive 10 comprises as essential parts an electric motor 17 and one on a circuit board 18 arranged electronic engine control 19 as well as the electric motor 17 with the locking element 6 connecting transmission element 13 , wherein the transmission element 13 a push rod 8th and a multicore cord 20 as a torsion element. Every vein of the cord 20 includes a number of suitable fibers. At the free end of the push rod 8th is a pestle 21 or the like, for actuating the locking element 6 the additional locking 3 serves. The one end of the string 20 is with the wave 24 of the electric motor 17 connected. In the simplest case, the twine to be twisted becomes 20 on the side of the electric motor 17 axially mounted and on the side of the push rod 8th linearly guided. One in the drive housing 14 firmly anchored thrust bearing 25 relieves the electric motor 17 or the engine mount of the train of twisted cord 20 ,

The string 10 For example, has a length of 200 mm and includes several wires. In one example, three wires each with a diameter of 0.12 mm are used. With a conventional, inexpensive 12 V electric motor with a torque of 5 mNm, for example, in one embodiment of the invention, a force of about 90 N can be transmitted in about 1 second, the shortening of the cord 20 and thus the path traveled 12 the push rod 8th about 15 mm.

Once an opening pulse is present, which can be issued for example via a button, an access control system or the like, and the engine control 19 receives a corresponding opening command drives the electric motor 17 the motor shaft 24 on and the string 20 is twisted, which shortens it. This will cause a rigid, perpendicular to the push rod 8th arranged connecting element 26 with the free end of the string 20 connected push rod 8th parallel to the string 20 is arranged, taken and in the direction of actuation 9 emotional. By extending the push rod 8th in the direction of actuation 9 become the closing traps 6 retracted so that the door leaf 7 can be opened.

The push rod 8th is in the drive housing 14 stored several times. These are two plain bearings 27 provided in which the non-round cross-section having push rod 8th is guided linearly. The Number of bearings can vary depending on the version. Instead of the two plain bearings 27 can the push rod 8th for example, be stored in a long sliding channel.

Has the push rod 8th reaches its end position, an engine brake provided for this purpose is activated in a further embodiment of the invention. The engine brake blocks the shaft 24 of the electric motor 17 , As an engine brake, for example, is used in the vicinity of the thrust bearing 25 positioned, actuated by means of an electromagnet blocking element 29 , The blocking element 29 is designed such that, with a corresponding control of the electromagnet by the motor control 10 , mechanically the rotation of the motor shaft 24 blocked when the push rod 8th extended and the electric motor 17 is de-energized. The blocking element 29 In the simplest case, it can be the moving armature of the electromagnet. By blocking the shaft 24 is in the extended position of the push rod 8th , ie with retracted closing traps 6 and thus unlocked door, prevents the twisted cord 20 independently untwisted and the wave 24 of the in this state advantageously electroless electric motor 17 drives. Alternatively to the use of a blocking element 29 the use of a known motor brake or a corresponding control of the electric motor 17 even through the engine control 19 , When the traps 6 to be extended again, the blocking device or the engine brake is released. One against the direction of actuation of the push rod 8th acting tension spring 28 with one end to the push rod 8th , at the other end to the drive housing 14 attacks, serves as a return spring. This pulls the push rod 8th back to their starting position. At the same time the electric motor 17 from the engine control 19 controlled in such a way that it rotates in the opposite direction and the fibers of the cord 20 can unravel cleanly. The retraction of the push rod 8th in the starting position can be slower than the procedure of the push rod 8th in the direction of actuation 9 , It goes without saying that the fibers of the cord 20 at least slightly tense during the entire time such that they can not behave uncontrollably at any time.

In one embodiment of the invention is one with the engine control 19 connected position sensor 30 positioned so that it is the zero position (initial position) of the push rod 8th or the zero position of the untwisted cord 20 detected. This is the position sensor 30 designed as a simple microswitch. Alternatively, a light barrier can serve as a position sensor. It is particularly advantageous if the position sensor 30 beyond that is capable of that of the push rod 8th to cover the distance traveled. The of the position sensor 30 The data obtained are from the engine control 19 processed. In a further embodiment, with the aid of the position sensor 30 the trajectory be taught during commissioning or at a later date. If the trajectory is known, the electric motor 17 be controlled in a manner adapted to the movement path.

If no linear movement, but a partial rotation of the fitting desired, as is the case for example in rotary latches, door handles or window handles, in another embodiment of the invention, the power transmission to the fitting by means of a transmission element 13 take place, a rotatably mounted roller 34 includes. The through the torsion element 20 provided traction is then about this role 34 redirected, as in 3 shown. Particularly advantageous is a variant in which, depending on the required or desired torque, the radius of this role 34 is changeable. Thus, if necessary and / or desired, different ratios can be selected.

If, during a movement of the fitting, large forces are required in both directions of movement, two twisting drives can be used 10 be used, which apply tensile forces in different directions. In the in 3 example shown are two Verdrillantriebe 10 on both sides of the central in the drive housing 14 placed role 34 arranged. The strings 20 are each about pulleys 35 to the outer circumference of the roll 34 guided and fastened there. The pulleys 35 make sure in particular that the cord 20 the motor shaft 24 not loaded diagonally.

Depending on which of the two electric motors 17 is driven, performs the role 34 due to the pull of the respective twisted string 20 a partial rotation in one or the other direction of rotation 36 , With the help of one with the engine controls 19 the two electric motors 17 connected angle sensor 37 In one embodiment of the invention, the angle of rotation of the roll 34 detected. The data of the angle sensor 37 be from the engine controls 19 processed. At the angle sensor 37 it may be, for example, an optical or a potentiometric sensor. For very simple drives, the use of a sensor is omitted, provided that the engine controls 19 are interconnected and the corresponding motor currents are evaluated.

In the locking element 6 In the case shown here, this is a rotatable blocking trap. The transmission element 13 includes next to the twisted strings 20 the role 34 , The crescent-shaped locking element 6 is rigid with the role 34 connected and is pivoted with this.

The role 34 can be tilted differently than shown, also by 90 degrees, so that the axis 33 the role 34 parallel to the waves 24 the electric motors 17 runs. A deflection of the tension of the cords 20 would then be done via other pulleys.

Such a drive 10 can also be advantageously used for the rotation of a door leaf or a window sash. Instead of a locking element 6 Then a turning or tilting device is provided, which by a on the roller 34 attached or with the roller 34 cooperating construction element is actuated.

In 4 Finally, another embodiment of the invention is illustrated. It is, as in 2 to a drive 10 for a linear movement.

On the circuit board 18 is a connector 40 for connecting the drive 10 to the connection line 11 intended.

A blocking device 41 serves for mechanical blocking of the push rod 8th and provides an alternative to a motor brake or to the blocking element 29 which is actuated by an electromagnet. The blocking device 41 but can also be used as a supplement to the engine brake or the blocking element 29 be used. The mechanical locking of the push rod 8th or generally the transmission element 13 or part of it is particularly advantageous if it is unfavorable, the string 20 to keep under tension, for example, because fibers are used that tire under certain conditions. Will the push rod 8th with the help of the blocking device 41 blocked, the fibers can through some controlled revolutions of the electric motor 17 to be relaxed. This possibility of relaxing the torsion element 20 when using the engine brake or the blocking element 29 is not given draws the blocking device 41 especially out.

In addition, optional is a facility 42 provided for buffering the supply energy, for example by means of electrolytic capacitors or batteries. The buffering is advantageously designed so that even at a power failure at least once controlled retraction of the push rod 8th ensures, so that the locking element 6 extend and the door can be safely closed. This is especially important for fire doors.

In a further embodiment of the invention, as in 4 shown next to the thrust bearing 25 at least one transmission element 43 for connection of the torsion element 20 to the wave 24 of the electric motor 17 available. In the transmission element 43 it may be one or more gears, a timing belt or the like. The resulting miniature gear is preferably designed such that it is the electric motor 17 or the engine mount from the train of twisted cord 20 relieved. Because with the help of the transmission element 43 Driven and driven speed and / or input and output torque can be varied, a reduction can be selected, the optimum adjustment of the drive power of the electric motor 17 to the parameters of a practical torsion element 20 , For example, to the diameter of the cord or the fibers allows.

In a further embodiment (not shown) are more with the push rod 8th connected cords 20 arranged in parallel and via coupled gears or another suitable coupling element of a single electric motor 17 driven.

In a further embodiment (not shown), the fibers of the cord 20 completely arranged in a sheath. The twisting of the fibers then takes place inside the casing. In the twisted state, the fibers are supported on the inner wall of the casing. The sheath is preferably a flexible, tubular sheath made of a suitable material, for example a plastic material. The cord inlaid with the cord 20 is preferably spirally wound and the resulting disc-shaped torsion element is between electric motor 17 and connecting element 26 placed, wherein at least the ends of the sheath in the drive housing 14 are fixed to a secure connection of the cord 20 to the wave 24 on the one hand and the connecting element 26 on the other hand. If necessary, the sheathing can be found in other places in the drive housing 14 be fixed so that uncontrolled movements of the sheathed cord 20 while twisting to avoid. In the in 3 In the embodiment shown, the disc-shaped torsion element can save space parallel to the roller 34 be arranged. In a further advantageous embodiment of the invention, the sheathed cord 20 not wrapped, but led once or several times around the corner. In this way, for example, the length of the string 20 in the in 2 shown variant are simply tripled by that of the electric motor 17 outgoing cord 20 just before the connecting element 26 in the direction of the electric motor 17 diverted, again until just before the wave 24 led, again deflected and finally again to the connection element 26 guided and attached to this.

In a further embodiment variant (not shown), the torsion element 20 supplemented by an additionally arranged in the drive train elastic construction element. By means of this additional construction element, the elasticity of the system can be increased in a controlled manner, namely by a suitable choice of the properties of the construction element. Preferably, the additional construction element is directly on the torsion element 20 attached. It has proven particularly advantageous if the additional construction element between the torsion element 20 and the connecting element 26 is arranged. The additional construction element is in the simplest case, a short, powerful coil spring.

In a further embodiment (not shown) is the linear or rotary movement of the transmission element 13 not completely, but only proportionally to a shortening of the torsion element 20 due. Another movement component of the transmission element 13 in this case is due to an additional drive. For example, after an initial movement of the transmission element 13 by the drive according to the invention 10 another, the opening or closing operation, etc. final movement of the transmission element 13 for safety reasons, only with the help of an additional drive, which must be controlled via a special safety release. Likewise, it may be in the drive according to the invention 10 is about this additional drive, if previously the transmission element 13 already moved with the help of a first drive.

So far, locking systems or actuating devices provided with motor drives have been described which are distinguished by the manner of the drive, namely by the use of the torsion drive according to the invention 10 distinguished. Hereinafter, another application of the present invention will be described, in which the movement of a originally manually operable securing and / or actuating element with a drive according to the invention 10 is supported in the manner of a servo drive. In other words, the force applied by a person to move a securing and / or actuating element by the drive according to the invention 10 strengthened.

At the actuator 1 For example, it is a hand-held handle for opening a window. The axis 44 the rotary handle is the performing actuator, which of the drive 10 is driven. For this purpose, the axis 44 via a torque sensor 45 with the role 34 connected, see 3 , The torque sensor 45 detects the torque produced by the person on the rotary handle or the torque difference between the rotary handle and the roller 34 and sends a corresponding signal to the engine control 19 further. The engine control 19 is designed such that it the electric motor 17 of the drive 10 such that the torque difference is minimized. With such a torque control, a servo drive is realized. As a result, the person operating the rotary handle prescribes the value with which the electric motor operates 17 with the help of the role 34 the axis 44 and thus moves the rotary handle. The force required to operate the twist grip is greatly reduced. In this way can be with simple means and with respect to the previously described embodiment of the drive according to the invention 10 very little extra effort in the form of the torque sensor and a corresponding modification of the engine electronics 19 provide a motor assisted safety and / or actuation device. This embodiment of the invention is particularly advantageously applicable to handicapped-accessible and age-appropriate fittings, for example for terrace or balcony doors.

Of course, the use as a servo drive is not limited to the generation of rotational movements. Even with linear movements of the drive 10 support the operation of the fitting in the manner of a servo. For example, in the in the 2 and 4 illustrated embodiments of the invention, a force sensor 46 in or on the pestle 21 be provided, which is a torque sensor 45 corresponding function perceives and the difference between the train or pressure on the push rod 8th on the one hand and on the push rod 8th on the other hand determine and a corresponding signal to the engine control 19 to transfer. As a force sensor 46 For example, an elastic element with strain gauges can be used.

This type of application of the present invention is not limited to actuators for opening, closing, tilting, turning, etc. of doors and windows or the like. A use in safety devices is possible, for example, when locking doors. Servo and backup function can advantageously be combined with each other such that the supporting servo function is only effective when a release is made, for example by a button, an access control system or the like.
