Description

There are z. B. from the DE 37 42 213 A1 Manual door drives are known, which have a drive unit with a power transmission device and are designed for mounting on doors with swing door. Depending on local conditions and application, the drive unit is mounted on the wing side or on the frame side. The power transmission device is supported on the opposite side, ie on the frame side or wing side. The drive unit comprises in this known manual door drive a closing spring unit and a hydraulic damping device. The closing spring unit and the hydraulic damping device are accommodated in a housing in which the output shaft is also mounted, to which the power transmission device is connected. This can be carried out in practice as a scissor linkage or Gleitarm slide rail device.

An electromechanical door drive, which is comparably formed from a drive unit and a corresponding power transmission device is z. B. from the EP 1 505 239 B1 known. The drive unit comprises an electric motor whose output shaft is connected to the power transmission device, which may be formed in the same manner as in the above-mentioned manual door closer as a scissor linkage or Gleitarm slide rail device. The electromechanical drive is mounted in a comparable manner on a door with swing door leaf, as described above for the manual door closer.

An essential function of the manual and electromechanical door drives is that at the end of the closing process, the door must safely enter the lock position by overcoming the lock catch. In the known manual door closers with hydraulic damping this is usually a so-called. Hydraulic end shock provided, which consists in that the hydraulic damping in the final phase during the closing process has a bypass. In practice, this often causes the door to slam shut with a loud bang when the door locks. If the end stop is set weaker, it may happen that the spring force of the closing spring at the end of the closing process is insufficient to close the door, d. H. It may happen that the door does not get into the closed position, the latch is not suppressed and the door leaves only ajar against the frame before reaching the closed position.

In the known electromotive door drives the motor opening and / or closing operation is controlled by an electrical control device. However, for the drive to function reliably and safely, constant maintenance and control adjustments are required. A failure of electrical components usually leads to the complete stoppage of the drive, so that said maintenance and inspection measures are permanently required. Furthermore, the electric drive basically requires a power connection. In practice, therefore, manual door operators are often preferred.

Furthermore, door pullers and door dampers are also known which are used on doors in buildings and can only be coupled with the door during the closing and opening process in the vicinity of the closing end position and thus act on the door only in this partial area of the closing and opening operation. These drive devices likewise have a drive unit to be mounted on the frame side or wing side with a power transmission device which, however, has a linkage which can be engaged and disengaged automatically. In the EP 2 468 998 A1 Such a drive is described with automatically engageable and disengageable linkage. Similar to a manual hydraulic door closer, the drive unit has a spring accumulator with hydraulic damping device, which cooperates with a driven-side sliding arm which automatically engages or disengages in a slide rail during the closing and opening operation.

The US 2,190,653 describes a conventional scissor linkage hydraulic door closer in combination with a door puller that automatically engages and disengages in a pivot bearing during the closing and opening operation as described.

In the in the 1.1 to 1.7 shown first embodiment is a door drive 10 mounted on a door. The door has a door leaf F, which is mounted about a vertical axis of rotation in door hinges B pivotally mounted in a stationary door frame R.

The door drive 10 is made up of a main drive 1 and an auxiliary drive 2 together.

The main drive 1 is designed in this specific case as a door closer, as Gleitarmtürschließer. It comprises a door closer unit with a door closer housing 1g which is mounted on the door leaf F. In the door closer housing 1g is a Türschließermechanik with closing spring and a damping device, preferably designed as a hydraulic piston-cylinder device. This door closer device in the door closer housing 1g forms the drive unit of the main drive. The output of this drive unit forms a rotatably mounted in the door closer housing door closer shaft 1w , Such as In 1.2 can be seen, is at the door closer shaft 1w connected a power transmitting linkage, as a sliding arm 1ka and slide rail 1ks is trained. Such as In 1.3 can be seen, is the sliding arm 1ka with a slider arranged at its free end 1kag in the slide rail 1ks guided. The slide rail 1ks is mounted on the fixed door frame R. The sliding arm 1ka with the slide rail 1ks forms the power transmission device of the main drive 1 ,

How best in the 1.1a . 1.1b and 1.1c can be seen, is the auxiliary drive 2 including its coupling device 20k at the front of the slide rail 1ks of the main drive 1 assembled. The auxiliary drive 2 acts in the illustrated embodiment via the coupling device 20k with the sliding arm 1ka of the main drive 1 together, as described in more detail below. As 1.1a shows are all the frame-side components of the main drive 1 and the auxiliary drive 2 including the coupling device 20k covered by a common filler panel. In the 1.1b and 1.1c this cover is removed. In 1.1c is also the case 2gg away. The housing 2gg forms the bearing housing of the drive unit 2g of the auxiliary drive 2 and additionally the bearing and guide housing of the coupling device 20k ,

The auxiliary drive 2 has a drive unit 2g on, in the illustrated embodiment as a gas spring 2GD with a piston rod 2gks is trained. The piston rod 2gks forms the output of the drive unit 2g of the auxiliary drive 2 , Between this output of the auxiliary drive 2 and the sliding arm 1ka the main drive is the said coupling device 20k connected. It engages the drive unit during the closing process and during the opening process 2g of the auxiliary drive 2 and the sliding arm 1ka of the main drive 1 automatically off and on, when the door reaches a predetermined opening angle, so that during the closing operation and the opening operation in a door angle range between the closed position and a predetermined opening angle, in the illustrated embodiment between the closed position and 10 ° door opening angle, the auxiliary drive is engaged. As long as the auxiliary drive 2 is engaged, it supports the main drive 1 by placing the sliding arm 1ka of the main drive additionally drives, ie in addition to the drive mechanism of the drive unit 1g of the main drive 1 , In concrete case, the auxiliary drive 2 designed as a closer actuator. The drive unit 2g comprises a gas spring as energy storage, which is charged during the opening process and discharged during the closing process. In addition to the energy storage, a damping device is included, with which the opening and closing speed can be influenced, preferably variably adjusted. The energy storage is during the opening process, in the phase of the opening movement in which the auxiliary drive 2 is engaged, charged and discharged during the closing process in the phase in which the auxiliary drive is engaged. In disengaged position, the energy storage is locked, ie it is neither charged nor discharged, it remains in the state of charge.

How best in the 1.3.1 to 1.3.5 , the 1.4.1 to 1.4.5 , the 1.5.1 to 1.5.5 , the 1.6.1 to 1.6.5 as well as the 1.7.1 to 1.7.5 can be seen, comprises the coupling device 20k a driven by the piston rod coupling body 20kk with slot slot and a clutch lever 20ke in one in the housing 2gg fixed pivot bearing is pivotally mounted and a guide pin 20kks having in the slotted slot of the coupling body 20kk is guided. The coupling body 20kk is resistant to movement with the output end of the piston rod 2gks connected and is in the housing 2gg slot-out. In this specific case, this is a guide slot in the housing 2gg in which one in the coupling body 20kk solid pen is guided.

In addition, in the housing 2gg another guide rail device 20kf arranged on the coupling body 20kk is longitudinally guided (sh. 1.2 ). When moving the piston rod 2gks becomes the coupling body 20kk in the case 2gg guided in this way. This is the over the scenery pin 20kks in the link slot of the coupling body 20kk guided clutch lever 20ke forcibly moved. The clutch lever 20ke is designed as a coupling claw and has at its free end a catching recess, with which he with one on the sliding arm 1ka arranged driver 1km interacts. In the engaged position is the driver 1km engaged in the catch recess of the clutch lever 20ke , In the disengaged position is the driver 1km out of engagement. In the 1.5 to 1.7 is shown as the clutch lever 20ke during the closing process near the closed position of the door with the driver 1km engages. The clutch lever 20ke is due to progressive movement of the coupling body 20kk driven by the output side piston rod 2gks , so swung forcibly controlled. About the engagement of the clutch lever 20ke with the driver 1km acts the auxiliary drive 2 on the sliding arm 1ka of the main drive 1 and thus supports the main drive 1 in the engaged phase of the closing operation under the action of the unloading gas spring 2GD , In the engaged phase of the opening process, the gas spring 2GD charged.

In the second embodiment, shown in the 2.1 to 2.3 , It is a modified embodiment compared to the embodiment of 1.1 to 1.7 , The modification consists only in that the coupling device 20k with the clutch lever 20ke directly with the glider 1kag of the sliding arm 1ka of the main drive 1 interacts and not directly with the sliding arm 1ka , Immediately means, however, in each case with the interposition of the slider 1kag or on the sliding arm 1ka fixed carrier 1km , The driver 1km is in the case of the embodiment of 2.1 to 2.3 in or on the slider 1kag arranged and the clutch lever 20ke interacts with this. In the engaged position is the driver 1km in engagement with the catch recess of the clutch lever 20ke and in the disengaged position he is out of this engagement. The operation is otherwise the same as in the embodiment of 1.1 to 1.7 ,

For the tape opposite side assembly arise with the embodiment of 1.1 to 1.7 however, advantages compared to the embodiment of 2.1 to 2.3 , The reason for this is as follows: As is known, running in the band-side mounting the slider 1kag in the slide rail 1ks at a small door opening angle with a reversal of direction, while on the other hand, the direction of rotation of the sliding arm 1ka remains in the same direction over the entire closing process as well as over the entire opening process, ie no reversal of the direction of rotation of the sliding takes place. The execution of 1.1 to 1.7 in which the coupling device is not on the slider 2kag but on the sliding arm 2ka engages, is therefore used in the Gegenbandmontage same as in the band-side normal assembly, and without a device modification must be made.

In the third embodiment, shown in the 3.1 to 3.4 , It is a modified version compared to the 2.1 to 2.2 , The modification consists in that the coupling device 20k designed differently. In the embodiment of the 3.1 to 3.3 has the coupling device 20k a clutch lever 20ke , which is also formed claw-like with Fangausnehmung and on the piston rod 20gks of the auxiliary drive 2 is articulated. In addition, the clutch lever 20ke however, in its middle section the same as in the embodiment of 2.1 to 2.3 in one with the housing 2gg of the drive unit 2g of the auxiliary drive 2 and with the slide rail 2ks of the main drive 1 fixed pivot bearing 20kea pivotally mounted and acts with its free end with Fangausnehmung in principle in the same way with a driver 1km together, in the skimmer 1kag of the main drive 1 is arranged, as in the embodiment of the 2.1 to 2.3 is explained. The housing 2gg takes the drive unit 2g of the auxiliary drive 2 including the piston rod 2gks and the coupling device 20k on. In the embodiment of the 3.1 to 3.4 is the driver 1km as a driving stick 1km formed in the slider 1kag in the horizontal plane of movement of the sliding arm 2ka however transversely to the direction of movement of the slider 1kag is arranged.

To control the clutch lever 2KE is in place of the coupling body 20kk however, in the execution of 3.1 to 3.4 a control lever 20ks intended. The control lever 20ks is formed in the illustrated case as a two-armed lever whose two lever arms form an apex angle of about 90 °. The control lever 20ks is in its apex area in one in the slide rail 1ks and / or in the housing 2gg rotatably mounted fixed pivot bearing. The one lever arm acts with its end with a control cam on the facing edge of the clutch lever 20ke together. The other lever arm of the control lever 20ks acts with its free end with a stop edge on the slider 1kag together, by the free end of this lever arm during the closing operation in a predetermined small door opening angle in abutment with the on the slider 1kag trained stop edge comes. At the same time comes the clutch lever 20ke with its catch recess in engagement with the driver 1km , Due to the drive connection with the piston rod 2gks of the auxiliary drive 2 is the at the stop edge of the slider 1kag in attack standing control lever 20ks in the Representation in the figures turned counterclockwise. The clutch lever 20ke associated lever arm is with its free end with the control cam of the clutch lever 20ke in stop and rotates the clutch lever during its rotation 20ke forcibly counterclockwise. The one with the clutch lever 20ke about the driver 1km engaged gliders 1kag of the sliding arm 1ka of the main drive 1 is taken along in the closing direction.

3.1 shows the situation during the closing process before the clutch engagement takes place, ie at a correspondingly large door opening angle.

The 3.2 shows the engagement as soon as the door leaf F reaches the predetermined small door opening angle.

The 3.3 shows the beginning of the rotational movement of the two levers, ie the rotational movement of the control lever 20ks through the stop position with the slider 1kag and the entrainment of the clutch lever 20ke by the action of the clutch lever 20ke through the control lever 20ks by turning the control cam of the clutch lever 20ke associated lever arm of the control lever 20ks the control cam acts and the clutch lever 20ke turns counterclockwise.

In 3.4 the closed position is shown. Both levers 20ks and 20ke are rotated in their final position counterclockwise. The control lever 20ks is still at the stop edge of the slider and the clutch lever 20ke is still in engagement with the driver 1km of the slider 1kag ,

The embodiment in the 4.1 to 4.5 (in the following briefly 4 called) is a modification of the embodiment of 1.1 to 1.7 (in the following briefly 1 called). The embodiment of 4 differs from the embodiment of 1 , As far as the design of the components and their assignment is concerned, let us start by focusing primarily on the 4.4 and 4.5 directed. In the embodiment in 4 is in contrast to the embodiments of the figures described above, the gas spring 2GD not pivotable on the slide rail 1ks of the main drive, but in one on the slide rail 1ks arranged fixed camp. Ie. the gas spring 2GD is with its housing firmly on the slide rail 1ks stored. The piston rods 2gks is in one with the slide rail 1ks fixed guide housing 20kh linear in the extension direction of the slide rail 1ks slidably guided. Between the free end of the piston rod 2gks and the clutch lever 20ke is a connecting link 20vl switched when the extension and retraction of the piston rod 2gks the pivoting movement of the clutch lever 20ke controls. The connecting link 20vl is this with its one end to the end of the piston rod 2gks and with its other end with the clutch lever 20ke each connected via a jointed bearing.

The clutch lever 20ke is in one with the slide rail 1ks stored in fixed bearing and is in the embodiment in 4 through the from the piston rod 2gks controlled connecting link 20vl controlled. The guide of the connecting link 20vl is formed such that the pivot, with which the connecting link 20vl with the end of the piston rod 2gks is connected, in a guide slot 20khs in the guide housing 20kh is guided. In the illustrated embodiment in 4 is the guide slot 20khs linear in the extension direction of the guide housing 20kh , ie also parallel to the extension direction of the slide rail 1ks , educated.

The determination of the angular position of the clutch lever 20ke in his from the driver 1km disengaged position, ie when the clutch lever 20ke in the door opening angle range greater from about 15 ° of the arranged on the slide arm driver 1km is disengaged takes place in the embodiment in 4 by a locking arm 20aa , Reference is made to the following 4.1 . 4.1a and 4.2 . 4.2a and 4.3 . 4.3a , The locking arm 20aa is on the guide housing 20kh pivotally mounted and is in the disengaged position of the clutch lever 20ke in its locked position (see 4.5 as well as the 4.1 . 4.1a and 4.2 . 4.2a ). In the locking position is the locking lever 20aa in alignment with the longitudinal extent of the guide housing 20kh and the guide slot 20khs , The locking arm 20aa is in this position with its free end in engagement with the free end of the piston rod 20gks that is, with the arranged at the free end of the piston rod guide pin, in the guide slot 20khs in the case 20kh is guided. In this locking position of the Arretierarms 20aa is the Arretierarm 20aa also aligned with the movement and power transmission direction of the piston rod 20gks , So that in this position a dead center position is obtained, in which the piston rod 2gks over the locking arm 20aa the clutch lever 20ke holds in its disengaged angular position in abutment and thus a dead center position is realized.

The dead center position is automatically canceled when the door reaches the specified door opening angle in the closing direction when closing, in the case shown this is a door opening angle of approx. 15 ° (see 4.2 and 4.2a ). In this door opening angle comes the locking arm 20aa in abutment with a control pin 1kaa on the sliding arm 1ka of the main drive 1 is arranged and will on further closing by the control pin 1kaa taken along, ie in the illustration in 4 turned counterclockwise. The locking position of the Arretierarms 20aa is thus repealed, ie the free end of Arretierarms 20aa comes out of engagement of the guide pin at the free end of the piston rod 20gks , At the free end of the Arretierarms 20aa a locking recess is formed in the in the locking position at the free end of the piston rod 20gks arranged guide pin engages. The piston rod 20gks becomes during the locking arm 20aa pressed out of engagement is first retracted a piece. Once the engagement of the Arretierarms 20aa but is canceled, there is an extension of the piston rod 2gks under the effect of the gas spring 2GD , In this extension of the piston rod is the connecting link 20vl emotional. The at the end of the connecting link 20vl arranged guide pin runs in the guide slot 20khs , The connecting link leads with his on the clutch lever 20ke hinged end pivotal movement from the guide housing 20kh out and thereby pivots the clutch lever 20ke in this door opening area due to the geometric arrangement in engagement with the driver 1km arrives. The clutch lever 20ke is the same as in the embodiments of 1 to 3 designed as a coupling claw with Fangausnehmung. The pivoting movement of the clutch lever 20ke driven by the gas spring 2GD acts on the driver 20km such that the further closing operation in the sense of a closing delay and simultaneous closing of the door under the action of the gas spring 2GD as an auxiliary drive. 4.3 shows the closed position of the door. The locking lever 20aa is swung out, ie not in the locked position. The locking lever 20aa is under the action of the sliding arm 1ka arranged tax pencil 1kaa held in this swung position.

During the opening process, a reverse action of the gas spring takes place as an auxiliary drive in comparison to the closing process. The gas spring is used during the opening process, as long as the clutch lever 20ke with the driver 20km engaged, loaded. It is done by an opening loss. The locking arm 20aa is by a return spring in its aligned alignment with the guide housing 20kh reset while the door is opened. The clutch lever 20ke is under the action of the driver 1km during the opening process, as long as he is with the driver 1km is coupled, swung back. The connecting link 20vl is doing while retracting the piston rod 2gks back into the guide housing 20kh into it swung. As soon as the predetermined door opening angle is reached, when the door is opened further, the clutch lever is disengaged 20ke from the driver 1km , The locking arm 20aa passes under the action of its return spring with its free end in abutment on a guide housing 20kh trained stop 20kha and finally in abutment with the guide pin at the free end of the piston rod 20gks , so that the dead center is set again (see 4.1 . 4.1a and 4.2 . 4.2a ).

There are modifications of the embodiments shown in the figures possible, in which the catching recess, which in the embodiments shown in the figures in the coupling element 20ke is formed, in modified embodiments, based on the embodiments of 1 and 4 based, the catching recess on the sliding arm 1ka is formed and modified versions, based on the versions of 2 and 3 based, the catching recess on the slider 1kag is trained. The respective associated coupling element 20ke has in these modifications on a driver which cooperates with the catching recess in a corresponding manner as in the embodiments of the figures.
