Description

The present invention relates to a drive device for transferring a door leaf into an open position and / or a closed position and a system for carrying out a corresponding transfer of a door leaf.

It is generally known that doors should be moved in a door frame between an open position and a closed position. This is necessary to obstruct a passage within a door frame in the closed position or to release it in the open position for a passage. It is also known to provide the transfer of a door leaf in the open position and / or in the closed position with a support or with a corresponding drive device. Two solutions are basically known. On the one hand, there are so-called passive door closer systems, which have a drive means with a passively provided driving force. These are often spring systems, which provide the driving force for transferring the door leaf in the closed position as a spring force available. These systems are relatively inexpensive systems, which, however, have the disadvantage that only very limited subsequent or targeted influencing of the driving force for a facilitated or assisted opening against this driving force is possible.

Further, it is known to provide active drive devices which are mounted in known solutions on the door frame. Here, active drive motors are used, which can provide the transfer of the door leaf both in the closed position, as well as in the open position. By using active and in particular electromotive drive devices, these are not only particularly large-volume components, but also particularly expensive solutions. Thus, a user for a drive of a door has previously limited to the purely passive systems with a cost-effective but correspondingly less comfortable embodiment on the one hand and the expensive but more comfortable, bulky solutions on the other.

It is an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is the object of the present invention to provide the previously known passive door openers with improved comfort in a cost-effective and simple manner.

The above object is achieved by a drive device with the features of claim 1 and a system having the features of claim 10. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that are described in connection with the drive device according to the invention apply, of course, also in connection with the system according to the invention and in each case vice versa, so that respect. The disclosure of the individual aspects of the invention is always reciprocal reference or can be.

According to the invention, a drive device is provided for transferring a door leaf into an open position and / or a closed position. For this purpose, the drive device has at least one drive means for acting on the door leaf with a drive force. With the help of a mounting interface, the drive device can be attached to the door leaf. In addition, a lever kinematics is provided with at least one lever element for supporting the driving force on the door frame. In this case, the drive means on a power receiver for receiving energy and for performing at least one energy-consuming action. The lever kinematics is also connected to transmit power to the drive means and is equipped with a Zargenschnittstelle for a force-transmitting connection with a Zargenelement a guide device of a door frame. In addition, the lever kinematics is equipped with a connection means for the transmission of electrical energy from a tergarner side power source to the energy receiver. A frame element and the frame interface may be a solution as a scissor linkage and / or a solution as a slide rail linkage.

A drive device according to the invention is based in particular on the known passive solutions. This means that it is in the drive means in particular a passive drive means, which has the necessary driving force z. B. with the help of a spring device passive and thus not changeable available. Of course, however, other drive means, in particular small and compact active drive means may be used in the form of small and compact electric motors as drive means for the drive device. However, the basic idea of the present invention is based on the known passive To provide drive means with an additional comfort function, which can be provided by the energy receiver in the inventive solution. It should be noted that even with a purely passive drive means, the bias of a spring element can be adjustable in order to provide a fundamental adaptation to the size and weight of the door can.

Thus, it is possible that in a drive device according to the invention this builds in a compact and cost-effective design on the known solutions for the purely passive systems of the drive devices. At the same time, however, it becomes possible to arrange an energy receiver on the door side of the door leaf and thus make it available as part of the drive means, which is independent of otherwise necessary structures in the wall area next to the passage or on the door frame. To ensure this, this energy receiver must be supplied with the appropriate energy from an energy source on the supply side. Such an energy source can, for. B. be a corresponding power connector or a battery device. While in the previously known solutions for the transfer of electrical energy on a door a free-running cable was used, which was guided substantially free from a fixed point on the door frame to a fixed point on the door, now in the inventive manner, the connecting means as part the lever kinematics trained. As a result, the connection means and thus the transmission of the electrical energy is substantially free of inspection and thus substantially protected against mechanical damage.

Thus can be supplied by the electrification of the door now the energy receiver with the desired electrical energy to the door cost, simple and mechanically protected manner.

As will be explained later, the energy receiver is used in particular to act on the drive means. However, in principle, other technical implementations are conceivable in which the energy receiver provides other or additional functionalities for the door leaf.

The possibility of an energy receiver on the door, it is now possible additional comfort features, especially those which require an electrical power supply, even in the previously known passive applications of the drive device available. In particular, these are comfort functions which have an active influence on an otherwise passively provided drive means. This will be explained in more detail later, in particular with reference to an opening force which can be provided by the energy receiver against the driving force of the drive means available.

It may be advantageous if, in a drive device according to the invention, the energy receiver generates an opening force, wherein the opening force at least partially counteracts the drive force of the drive means. This includes both direct and indirect counteraction. The opening force is transferred by the drive means via the lever kinematics to the corresponding frame interface, so that the door is pressed in the direction of the closed position and / or in the direction of the open position or is pulled. This means that now can be counteracted with the help of the opening force in the opposite direction of this driving force. The actual force which arrives at the door or is perceived by the user of the door is therefore the resultant force which results from the addition between the opening force on the one hand and the driving force on the other hand. It should be noted that the opening force and the driving force does not necessarily have to act in the exact opposite directions. Rather, it is also conceivable that an angle which is not equal to 180 ° is present between driving force and opening force, so that the resulting force can be determined via a force balance of the corresponding force vectors. By correlating a Gegengegenens between the opening force and the driving force now an otherwise purely passive and unchangeable drive means with a correspondingly defined passive and unchangeable driving force in the perception for the door or for the user of such a door leaf can be changed. Thus, by varying the opening force by means of a corresponding control of the energy receiver, the resulting force on the door leaf itself can now be changed and adapted to a corresponding usage situation.

It may be advantageous if, in a drive device according to the invention, the energy receiver has at least one assistance mode, an automatic mode, a braking mode and / or a rest mode. Of course, only individual suggestions are to be understood among the individual modes, so that a multiplicity of further different modes, in particular also a variable variation in a preferably continuous manner between the individual operating modes is conceivable. The following briefly explains the cases presented here for the individual modes of the energy receiver. there For example, it is a so-called support mode. While in the known passive solutions the door had to be opened against the driving force, this could mean that especially weak or otherwise disadvantaged persons could not complete the opening process of the door, not completely or only with great effort. Now it is possible that the door opening request is recognized on the door, z. B. by an appropriate opening sensors, and then with the help of the energy receiver, the opening force so supporting the driving force counteracts that the closing force to be overcome, which is provided by the driving force, significantly reduced or even canceled altogether. In other words, by counteracting the energy receiver with the opening force, a passive door closer is reduced in effect or even eliminated entirely in terms of driving force. By significantly reducing or even eliminating a door leaf in this way, the corresponding user of the door leaf in the support mode of the energy receiver can open the door more easily or even substantially completely without any counterforce. An automatic mode is to be understood that the opening force is even greater than the driving force. Thus, when detecting an opening request on the door not only the driving force is reduced, but rather actively moves the door in the open position. This goes beyond the mere support of the otherwise carried out by the user of the door leaf door even out. For the purposes of the present invention, a quiescent mode is quasi an energy receiver which is switched off and which has no or only a slight influence on the driving force with the aid of its opening force. A braking mode is to be understood as meaning that a door leaf passively through the Driving force to be closed again. In order to make this closing process more comfortable and, in particular, slower, such a braking mode can reduce the driving force in the direction of the closed position, so that this closing movement is carried out more slowly or even later after a defined hold-open time.

In order to provide the above individual modes, it may be advantageous if in a drive device according to the invention in the assist mode, the opening force of the driving force between 10% of 100%, in the braking mode when transferring the door leaf in the closed position between 10% to 90% and in Sleep mode does not counteract. In the automatic mode, the opening force is preferably greater than the driving force. By means of this force correlation between opening force on the one hand and driving force on the other hand, a possibility can be provided for correspondingly to be able to provide the different operating modes explained in the preceding paragraph. It is still irrelevant in a first step in which way the energy receiver is actually formed. So are the later explained embodiments, z. B. in the form of a hydraulic drive, in the form of a pneumatic drive or in the form of an electric motor drive just as conceivable, as well as other combinations or different technical implementation forms.

It is also advantageous if, in a drive device according to the invention, the energy receiver has a control device for regulating and / or controlling the drive means. Such a control device thus eliminates an otherwise necessary external monitoring or external control. Rather, without an additional control unit or control unit within the overall system the drive device itself, the monitoring and control of the individual operating modes are performed. For example, it is conceivable that the door opening angle is monitored by means of a sensor system. As soon as the user of a door leaf begins to move this door open, this is detected as a desired opening from a defined minimum door opening angle. This can be z. B. a door opening angle of 2 °, to be about 5 °. Subsequently, the drive means is acted upon by the control device with the corresponding opening force or offset the opening force of the energy receiver in the defined manner for the selected operating mode of the driving force in a counteracting state.

It is also advantageous if, in a drive device according to the invention, the attachment interface can be brought into operative connection with a fastening receptacle on the door leaf, the attachment receptacle corresponding in particular to a standard door. Thus, it is possible to equip existing operating situations of purely passive drive devices with the functionality of the invention. The use of standard interfaces, which can be formed between mounting interface and mounting receptacle, it further allows that can be used in existing project planning but also in new project planning on known dimensions. This not only makes it possible to provide a retrofit functionality in existing situations, but also to be able to take account of the new and inventive comfort functions of an advantageous drive device in future plans.

Moreover, it is advantageous if in a drive device according to the invention, the connecting means is at least partially configured as a flat cable and / or ribbon cable, in particular as a flexible circuit board and / or the connecting means is at least partially configured as a round cable. These are of course only individual alternatives, which combined
or alternatively can be provided. The use of flat cables or flat cable or flexible printed circuit boards has the advantage that particularly in the area of the connection interfaces to the drive means or to the frame interface, a corresponding rotation compensation can be made particularly easy, inexpensive and easy. The use of known round cables leads to a particularly simple and inexpensive embodiment of a drive device according to the invention.

A further advantage may be that, in a drive device according to the invention, the lever kinematics at least in some sections have a bent course, in particular that the cranked course extends in the region of a closing section between the lever kinematics and the drive and / or in the region of the connection section between the lever kinematics and the frame element , Such a cranked course makes it possible to provide a particularly flat design, in particular in the vertical orientation in the mounting situation. At the same time it is possible in this way in the transitional sections, in which a rotational compensation at the transition of the connecting means must be made to provide a corresponding space available to provide this rotation compensation for appropriate structural measures can. In addition, a mechanical stabilization is achieved by the cranked course, in particular in the force-introducing or kraftabstützenden sections of the lever kinematics.

The Figures 1 and 2 show basically how a door 2 with a drive device 1 can be operated. The two positions, namely the open position I according to FIG. 1 and the closed position II according to FIG. 2 to distinguish. If a user wants to move a door 2 into the open position I, he exerts a corresponding pressure on the door 2 in FIG. 1 down from. This causes the door 2 moves into the position as they FIG. 2 shows. In this case, a drive means 3 is biased by the mechanical positive gear of the lever kinematics 5, so that a driving force AF builds up which z. B. can be provided by a spring device of the drive means 3 available. In order to provide the necessary length compensation for the lever kinematics 5 and the individual lever elements 5.1, a frame interface 8 with a frame element 8.1 by a guide device 8.2 is provided on the door frame 6. In the position as they open position I in FIG. 2 is shown, a spring device has now been charged accordingly within the drive means 3, so that now a driving force AF acts on the door 2 in the closed position II with a corresponding force. In order to ensure that the further movement is possible in a comfortable and, above all, facilitated manner, an opening force OF of the drive force AF can be counteracted with the aid of an energy receiver 7.1 of the drive means 3. The individual operating modes are described below with reference to the FIGS. 3 to 6 explained in more detail. In order to supply the energy receiver 7.1 with appropriate electrical energy, runs through the linkage kinematics 5, a connecting means 7, which supplies the electrical energy from a turzargenseitigen energy source 7.2.

The FIGS. 3 to 6 show different operating modes. Reference is made to the correlation of the opening force OF and the driving force AF and the resulting force RF. Further, in the four diagrams on the X-axis, the movement between the closing position II and the open position I and on the Y-axis, the associated force is displayed.

FIG. 3 shows a possibility of a so-called support mode. In this assist mode, there is a correlation between a drive force AF configured as a spring characteristic and a continuously applied opening force OF. This can be z. B. by means of an electric motor, a pneumatic drive and / or a hydraulic drive. As soon as the door leaf 2 is actuated and is to be moved into the open position I, the opening force OF of the driving force AF now opposes. Due to the fact that this counteracting takes place, the resulting force RF is reduced so that, as it were, the user-perceivable spring characteristic shifts downwards, thus making it easier and more comfortable to open the door leaf 2.
FIG. 4 shows another solution of a support mode. Here, the opening force OF is not performed or provided in a continuous manner but also in the form of a linearly increasing characteristic system. This results over the entire or substantially entire opening process from the closed position II to the open position I, a constant resulting force RF, which further increases the comfort in the implementation of this opening process.

FIG. 5 shows that by a corresponding increase in the opening force OF starting from the FIG. 3 the comfort can be further increased or even a large part of the opening movement essentially resistance-free opening movement for the door 2 is possible.

FIG. 6 shows an automatic mode in which the opening force OF is always greater than the driving force AF. This will be in the FIG. 6 generates a negative resultant force RF, so that not only a force-free opening of the door leaf 2 is possible, but rather the door 2 is actively moved by the negative resultant force RF in the open position I.

The FIG. 7 shows a system 100 according to the invention, which is attached to a door frame 6 and a door 2. About the lever kinematics 5, only the driving force AF of the drive means 3 of the drive device 1 can be supported in turn on the frame interface 8.

The drive device 10 is here equipped with the mounting interface 4, which is fastened to a particular designed as a standard interface mounting receptacle 4.1 of the door leaf 2. The attachment can be carried out in particular in a reversible manner by means of a screw.

FIG. 8 shows a way as with the aid of a cranked connection portion 12 with increased mechanical stability, an advantageous space can be created in order to provide in particular the already explained several times rotation compensation in the connection to the drive means 3 and the frame interface 8.

The above explanation of the embodiments describes the present invention solely by way of example. Of course, individual features of the embodiments, if technically feasible, can be combined freely with one another, without departing from the scope of the present invention.
