Description

The present invention relates to a linkage system of a drive device of a two-wing swing door, a drive device of a two-wing swing door and a method for mounting a corresponding linkage system.

It is known that double-wing swing doors can have drive devices. These are usually provided with drives, which are able to provide, in particular electric motor, an opening and closing of the respective door leaf. In two-wing swing doors is to distinguish between the so-called passive wing and the so-called active leaf. These are two different door leaves, which overlap each other in the closed state at least partially over a fold. Accordingly, closing the double-wing swing door of this embodiment, the closing order is crucial to prevent jamming of the two leaves against each other. It is also known that such hinged doors are designed as fire doors, so that the closing movement can take place without electromotive assistance via a mechanical closing device under a prestressed closing spring. To ensure that the described closing sequence control is complied with, a braking device is provided for this purpose in known drive devices, such as the documents DE 10 2009 004 506 A1 or DE 10 2009 004 498 A1 describe. The operation for the closing sequence control is achieved by activating the braking device. So will when sharing the mechanical closing force exerted this first on the inactive leaf, and braked during this movement over the braking device in activated training form of the active leaf or held still. A linkage system detects when the inactive leaf has reached its closing position or has almost reached it. Only at this time, the brake device is released, so that the mechanical closing force can now perform the closing of the active leaf.

Disadvantage of known drive devices is that the necessary linkage system is relatively complicated. In particular, the necessary return device for the linkage system, which is able to retract the corresponding rod, which may be a control rod, back to the starting position, is designed relatively complex. Particularly disadvantageous is the space required for this return device. However, a waiver of the return device is not possible, since otherwise no return movement of a trained as expanding mandrel rod end of the linkage system from the engagement in the braking device would be possible. Thus, a closing of the brake after completion of the door movement would no longer be possible or only with great effort.

It is an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide in a cost effective and simple manner, the production and / or assembly of the return device or the linkage system preferably with low error rate.

The above object is achieved by a linkage system with the features of claim 1, a drive device with the features of claim 10 and a method having the features of claim 11, 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 linkage system according to the invention, of course, also in connection with the drive device according to the invention and the method according to the invention and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or can be.

An inventive linkage system in a drive device of a two-wing swing door is equipped with a reset device. This return device has a first stop and a second stop, between which a spring device extends. In this case, the first stop on a mounting portion for attachment to the drive device against a translational movement. The second stop has a power transmission section for power transmission for translational movement of a rod of the linkage system. In this case, the spring device acts on the rod via the force transmission section in a first direction with a force. An inventive linkage system is characterized in that the rod extends at least in sections through the spring device, the first stop and the second stop.

An inventive linkage system is used in the drive device for the activation and for the provision of the brake device of the associated drive of the drive device for the active leaf. This can be done in the manner already described, the control of the closing sequence between the inactive leaf and the active leaf. For the provision of the linkage system, in particular designed as a rule rods Rods with an expanding mandrel at the end, which can engage in corresponding brake shoes of the braking device of the drive device, the return device is provided. Thus, the movement is made available in the deactivating position for the braking device by corresponding carriage movements of the respective drive of the drive device. The return movement is not possible, however, since in the opposite direction of movement decoupling takes place between the respective carriage of the drive of the drive device and the rod or the rods of the linkage system. Accordingly, a separate return device is necessary for the return movement, for the extraction of the expanding mandrel and thus the activation of the braking device, as explained in detail in the documents described in the introduction.

A spring device according to the present invention extends between the two stops and preferably biases them against each other in this way. In this case, the spring device can have any spring-elastic training. For example, elastomeric materials are conceivable to form the spring device. However, in particular spring variants in the form of steel spring elements are preferred. This may be, for example, a coil spring or a leg spring.

The spring device is biased between the two stops so that a force is transmitted to the rod in a first direction via the power transmission section. This first direction corresponds to the return direction of the corresponding rod and thus the movement of the rod out of the brake device. In other words, when releasing the brake device and thus when pushing the rod end in the form of an expanding mandrel for releasing the Brake shoes of the braking device forced a movement against the spring force of the spring device. The spring is accordingly compressed and the spring force increases. Missing now the associated holding force in this position, for example, by a then no longer contacting carriage of a corresponding drive of the drive device, namely because the inactive leaf is opened, for example, the now further biased spring force of the spring device, the return movement of the rod and thus a withdrawal of the Rod end, which may be formed as expanding mandrel, force. The return movement is achieved by a reduction of the biasing force in the spring device.

A significant advantage of the present invention is the significant reduction of the necessary installation space. By combining the volume between the spring device, first stop, second stop and the rod of the linkage system, a reduction in space requirements is achieved. This can also be a partial reduction take place, so that the manufacturing effort in terms of time and cost can be improved.

Also of advantage in a linkage system according to the invention is the simplified assembly. Thus, the rod also serves as a guide for the spring device, so incorrect assembly can be excluded with a higher probability. Also, the power transmission is particularly easy in this way possible because in particular Kippmomentübertragungen between the spring device and the rod are reduced or even completely avoided. The assembly is thus less error prone and beyond the setting of the desired biasing force of the spring improved.

In the context of the present invention, a fastening section is to be understood as any form of fastening which prevents a translational movement of the first stop relative to the drive device. For example, a clamping or frictional connection may be provided. Also, active fasteners using fasteners, such as screws or punch rivets, are conceivable in the present invention case.

The linkage system may include one or more rods. In particular, it is preferable if separate rods, ie a first rod, which can also be referred to as a walking-wing rod, and a second rod, which can also be referred to as a stationary-blade rod, are provided for easier assembly. These separate rods are connected to each other via a coupling device which transmits the translation movement in both directions between the rods.

The two stops are in the inventive manner against the biasing force of the spring relative to each other movable. Since the first stop is arranged fastened to the drive device via the attachment section, the second stop can accordingly move relative to this stop and thus relative to the drive device by increasing the pretensioning force of the spring device. The individual components, in particular the two stops, are preferably made of a plastic, for example of thermoplastic material. A particularly preferred method of manufacture is an injection molding process for the two components of the stops.

It may be advantageous if, in a linkage system according to the invention, the spring device has a spring element in the form of a spiral spring wherein the rod extends parallel in the interior of the spring coils of the spring element. For a cost-effective and particularly simple embodiment of the spring device is given. In particular, the rod thus extends substantially completely through the spring element in the form of the spiral spring, so that the advantage achieved with respect to the required space can be maximized. In addition, coil springs are particularly simple and inexpensive components, which accordingly can achieve a cost reduction of the entire boom system. Also, the assembly is improved because a stabilizing effect against unwanted buckling of the coil spring during assembly is generated by the extension of the rod by the coil spring. Of course, however, fundamentally other spring element shapes, for example elastomer springs or leg springs, are also conceivable.

It is also advantageous if in a linkage system according to the invention according to the preceding paragraph, the rod axis of the rod and the spring axis of the spring element are arranged parallel to each other with an assembly distance to each other. This mounting distance is greater than zero and smaller than the diameter of the spring element. This makes possible an offset which, as it were, shifts the rod within the spring element into a region laterally or above the spring axis. This makes it possible to gain space especially at a mounting of the linkage system and the entire drive device on top of the swing door. In particular, in the case of installation situations that are as flat as possible, assembly advantages can be achieved here.

It is also advantageous if, in a linkage system according to the invention, the first stop and / or the second stop walls have, which surround the spring device. These walls are preferably formed such that a substantially closed housing is formed to einzhausen the spring device. This ensures a protection against unwanted influence from the outside. In particular, the ingress of contaminants is reduced in this way or even completely prevented. In the formation of the walls are in particular plastic components, which are preferably formed integrally or even monolithically with the respective stop. In addition, the walls form stops to the outside, so that buckling of the spring element is prevented during operation. The walls thus provide a possible maximum range of motion for the spring device.

It is also advantageous if, in a linkage system according to the invention, the first stop and the second stop have guide means for guiding a movement of the first stop relative to the second stop while changing the spring force in the spring device. As has already been explained, during movement of the linkage system, in particular of the rods of the linkage system, relative movement of the two stops relative to one another takes place while changing the spring force in the spring device. This relative movement is preferably performed and thus predetermined in a defined manner. For example, the second stop may comprise guide pins as guide means, which engage in corresponding guide grooves or guide slots of the first stop. In order for a defined movement is specified and in particular a tilting of the two stops with respect to each other with respect to the necessary freedom of movement avoided. Of course, other embodiments of the guide means are conceivable.

Further, it is advantageous if in a linkage system according to the invention, the first stop and the second stop each have a stop portion which limit the movement of the two stops relative to each other in at least one direction. A stop section is to be understood as an end stop, which sets an end point for the relative movement of the stops relative to one another, at least in the direction of deactivation of the braking device. This ensures that the spring device is not completely discharged and the stopper, so to speak, releases from the spring device. This should be avoided in order to actually ensure the desired return movement. This stopping effect also serves to set and maintain a desired biasing force in the spring device within the assembly. In this case, the individual stop sections can be made adjustable with respect to each other with regard to their geometric correlation in order to increase the preload force by reducing the maximum distance between the two stops. For mounting the linkage system according to the invention is placed after placing the spring device on the second stop this together with the second stop in the first stop, and thereby preferably tilted. After a tilting back, the respective stop section serves to prevent the second stop from being pressed out based on the spring force of the spring device.

It is also advantageous if, in a linkage system according to the invention, the first stop and / or the second stop have at least one holding section for holding the spring device, in particular in a form-locking manner. Thus, such a holding portion may be formed, for example, as a spring mandrel. The holding portion has, for example, a projection with a chamfer in order to facilitate threading the spring device, in particular in the form of a spiral spring. Also, depending on the length of the holding portion, a lateral breakout or clipping of a spring element designed as a spiral spring is avoided with a higher probability.

It may also be advantageous if in a linkage system according to the invention, the second stop is designed for a tilting mounting on the first stop under bias of the spring device. Since the spring device extends between the two stops, a movement of the second stop in the direction of the first stop is possible only by increasing the biasing force of the spring device by a tilted insertion of the second stop. After inserting and increasing the biasing force of the second stop is brought back into its vertical position, so preferably prevent the stop sections already described now complete squeezing of the second stop by the spring device. This movement is preferably carried out with an explicit assembly tool, which preferably has a mounting projection, which can engage the second stop. For example, the second stop has an associated opening for the rod, wherein the assembly tool, which is also the subject of the present invention, can engage via a mounting projection with the same or similar geometric extension cross-section.

It is also advantageous if, in a linkage system according to the invention, the second stop has a form-fitting section for an at least partially positive contacting of the rod and / or a coupling device of adjacent rods in order to avoid tilting of the rod to the return device. This is in particular a radial positive connection in order to produce the anti-tilt device. Avoiding tilting is in the Understand technical meaning, so that of course technically permissible tolerances for slight variations in the angle of attack of the rods can be admitted to the respective stop. For example, the form-fitting section may be formed as a cylindrical or round recess in order to provide the corresponding radial form-locking device. Also, the positive connection portion and / or the respective coupling device may be provided with a filling bevel or a bevel in order to facilitate the assembly on.

Likewise provided by the present invention is a drive device of a two-wing swing door with a first drive for driving a passive leaf and a second drive for driving a leaf. Each drive has a mechanical closing device for closing the swing door. The closing device of the second mechanical drive has a brake device for braking the active leaf to achieve a closing sequence of the swing door. A drive device according to the invention is characterized in that the braking device is controlled via a linkage system according to the invention. Accordingly, a drive device according to the invention brings the same advantages as have been explained in detail with respect to a linkage system according to the invention.

• Anordnen einer Stange mit einer Erstreckung zumindest abschnittsweise durch die Federvorrichtung, den ersten Anschlag und den zweiten Anschlag.

A further subject of the present invention is a method for assembling a linkage system according to the invention, comprising the following steps:

• Providing the first stop and the second stop,
• Arranging the spring device on the second stop,
• Moving the second stop with the spring device in a position relative to the first stop for forming a bias voltage of the spring device,

Further advantages, features and details of the invention will become apparent from the following description in which embodiments of the invention are described in detail with reference to drawings.

The Fig. 1a to 1c show a possibility of a double-winged swing door 200 with a closing sequence control. Thus, this swing door has a fixed leaf 210 and a moving wing 220. These two are each provided with a fold, so that a defined closing sequence for a complete closing of the swing door 200 is necessary. Accordingly, as in the movement of Fig. 1 a to 1 c is shown, first the stationary leaf 210 and then the active leaf 220 are moved to the closed position.

In order to be able to ensure the preceding closing sequence, a drive device 100 is preferably according to FIG Fig. 2 intended. It is provided with two drives 110 and 120, which each act on the inactive leaf 210 and the active leaf 220. In order to ensure that even under a power failure, a mechanical and thus power-free closing of the two wings 210 and 220 is possible, a mechanical locking device 112 and 122 is provided in each case. These will be at Opening the swing door 200 biased and can perform a closing of the swing door 200 under release of the biasing force of the respective spring element even in case of power failure. In addition, the second drive 120 has a braking device 124, as for example in Fig. 3 is shown in more detail. About brake shoes, which are biased from both sides via spring elements, a braking effect is exerted on the drive 120. This braking effect can be canceled if a rod end in the form of an expanding mandrel is pressed into a expanding mandrel receptacle 126 by a linkage system 110. This occurs when the swing door 200 during a closing operation in the position of Fig. 1b and thus now in the closing sequence and the active leaf 220 can perform the closing movement.

For the provision of the linkage system 100, that is for the withdrawal of an expanding mandrel as a rod end of the rod 14 except the Spreizdornaufnahme 126, a return device 20 is provided.

One possible reset device is in Fig. 4 shown. It shows that when inserting the rods 12 and 14 into a corresponding Spreizdornaufnahme 126 on the brake device 124 (in Fig. 4 Thus, a movement from right to left) while holding the first stop 30, a relative movement of the second stop 40 takes place under compression of the spring device 50. Now, if the corresponding holding force is removed or removed, then by relieving and reducing the biasing force of the spring device 50, the second stop 40 is again to the right in the position according to Fig. 4 moves and thus the linkage system 10 and thus the rods 12 and 14 are also moved to the right to activate the brake device 124 again.

The embodiment of the Fig. 4 is substantially closed, so that both the first stop 30, and the second stop 40 walls 34 and 44 have to provide a substantially closed housing for the spring device 50 is available. It can also be clearly seen here that the spring device 50 is designed as a spring element 52 in the form of a spiral spring which has a spring axis FA. The rod axis SA of the rods 12 and 14 is arranged offset parallel to a mounting distance M, wherein the rod 12 extends completely through the return device 20 and thus the stops 30 and 40 and the spring device 50. Already in Fig. 4 the particularly compact design is recognizable.

It can also be seen that both stops 30 and 40 each have a holding section 39 and 49 in order to achieve holding of the spring device 50. In this case, the two holding portions 39 and 49 extend between the spring coils 54 and thus facilitate a tilt-safe arrangement.

Next is the Fig. 4 it can be seen that a translational fastening situation, for example to a housing of the drive device 100, is possible via a fastening section 32, here the outer side of the first stop 30. The second stop 40 has a power transmission section 42, which here allows a power transmission in an indirect manner via a coupling device 16 on the rods 12 and 14. In addition, a positive connection section 41 is provided, which forces a positive connection in the radial direction and thus avoids tilting of the rods 12 and 14 relative to the return device 20.

Fig. 5 shows a further embodiment of a return device 20 according to the present invention. Again, there is a coupling device 16, so that the not shown extension of the rods 12 and 14 can also be done by both stops 30 and 40 and a spring device 50, also not shown. The 6 and 7 For better clarity, different cross-sections of this embodiment of the restoring device 20 are shown. In this embodiment, it is advantageous that guide means 46 and 36 are additionally provided. Thus, 30 guide grooves are provided as guide means 36 for guiding guide pins as a guide means 46 of the second stop 40 in the first stop. The assembly can preferably take place in a tilted manner, so that after insertion of an erection of the second stop 40 to a mounting situation according to the Fig. 5 to 7 leads.

The Fig. 5 to 7 In addition, the provision of stop sections 38 and 48 can be seen. These secure the second stopper 40 against being pushed out by the spring device 50. Thus, an end position of the maximum distance positioning of the two stops 30 and 40 relative to each other is possible.

The 8 and 9 show an alternative embodiment of the return device 20. This differs in particular by larger openings in the walls 34 of the first stop 30. Also here a reduction in the dimension of the construction for the desired stop sections 38 and 48 has been achieved. In addition to a reduction in the cost of materials and a weight reduction was achieved.

The above explanation of the embodiments describes the present invention solely by way of example. Of course, individual features of the embodiments, if technically useful, freely combined with each other, without departing from the scope of the present invention.
