That is, the term door is used in the The present application also understood a gate, a window and / or another closure device with movably mounted wing. But door opener does not mean that an aggregate must be provided to drive the opening movement of the door; However, such an aggregate may be provided as an additional device.

The term wing or door is understood in the present application, a rotary wing and / or a sliding sash consisting of one or more such wings. It may also be a non-negotiable, comparable closure device in the construction or furniture sector, such. also a smoke damper.

The term lock latch in the present application is understood to mean the latch cooperating with the door latch. It can be rigidly mounted or spring-mounted. It does not have to - but can - be arranged in conjunction with a lock.

As far as the state of the art is concerned:

By way of example, the DE 42 29 239 C1 called. This document describes a door opener of the type mentioned. The locking device is formed in this door opener as an electromechanical device consisting of a lever device and an electromagnet. The lever mechanism composed of a one-armed lever and a two-armed lever engages in this known door opener directly on the door opener trap constructed as a pivoting latch. The lever device is locked via the electromagnet in the case of energization, so that the door opener latch is thus present in energized electromagnet in its blocking position and is released when energized electromagnet. This known door opener thus operates according to the so-called closed-circuit principle; in contrast to the likewise known working current principle, in which the release position at energized electromagnet and the blocking position is present at non-energized electromagnet.

An appropriately designed door opener is also in the DE 103 47 528 B3 described. In this door opener the release of the door opener latch may be hydraulically controlled.

The from the DE 42 29 239 C1 Known door opener that works according to the quiescent current principle is a so-called escape door opener, ie it is designed for use in escape doors.

This stop assembly is designed so that a wedge-like displacement effect is on the stop by the locking lever and thus safely comes with its power off the locking lever from its stop position, even if pressure is exerted on the door.

From the DE 10 2004 037 827 A1 an electric door opener is known in which the trained as a pivotal latch door latch is adjustable in stages. This stage adjustment is realized according to this document, that the door latch is composed of a base body and a, the case locking edge having blocking body. The main body and the locking body are coupled to one another via a complementary interlocking locking toothing and fixable on each other via a screw. about this toothing is the adjustment stepwise depending on the tooth spacing possible. The adjustable locking body is referred to in practice Aufschraubstück. The adjustment must be made manually.

From the EP 0 841 447 A1 a door opener is known whose door opener latch is infinitely adjustable by the door opener latch is composed of a base body and an infinitely adjustable via an Exentereinrichtung locking block. Again, the adjustment is done manually.

FIG. 1 shows a schematic view of a door opener with hydraulic detection of the locking member 2 via an electrically actuated hydraulic valve 5. The door opener latch 1 is designed as a pivoting latch. The locking member 2 is formed as a hydraulic piston 2k of the hydraulic circuit of the locking device. The hydraulic piston 2k is guided as a working piston in a hydraulic cylinder 2z and forms a piston-cylinder device 20 of the hydraulic circuit of the locking device. In the hydraulic circuit, except for the piston-cylinder device 20 with the hydraulic piston formed as a locking member 2, a surge tank 3z provided with a return spring 3f. This acted upon by the spring 3f piston-cylinder unit forms a hydraulic return device 30 of the locking member. The hydraulic piston-cylinder unit 20 and the surge tank 3z, that is, the hydraulic return device 30, are - as in FIG. 1 recognizable - connected via hydraulic channels, wherein in the one hydraulic channel, a check valve 4 and in the other hydraulic channel, the valve 5 is arranged, which is electrically controllable to turn on and off the determination of the piston 2.

This door opener can work according to the quiescent current principle. In this case, the valve 5 is connected electrically zuhaltend. That is, as long as the valve is energized, the valve is closed and thus locks the locking element 2 in its blocking position. When the power is turned off, the valve opens.

As a variant, it is possible to operate the door opener also in the working current principle. For this purpose, the valve 5 must be switched electrically open, that is, as long as the valve 5 is not energized, it is closed by locking the locking element 2. When the valve 5 is energized, it opens with the release of the locking element. 2

In addition, in a hydraulic connection channel also a pressure relief valve may be arranged, which ensures that when a Overload on the door, the hydraulic lock is released by the pressure relief valve opens. The pressure relief valve may preferably be variably adjustable to a predetermined overload.

In the embodiment in FIG. 1 is for the control of the locking member 2, a hydraulic circuit is used, ie the working medium of the circuit is hydraulic oil. Instead of hydraulic oil can also be a comparable liquid or a gaseous working medium, eg. As air, are used.

The door opener is preferably mounted on the stationary frame of a door. In the closed position of the door, the door latch latch 1 engages behind a latch arranged on the door latch or the like. The latch is in FIG. 1 not shown. The latch may be formed conventionally, ie as a resilient latch with an inlet slope over which the latch when closing the door by the door latch 1 is suppressed and finally engages behind in the closed position and is in abutment with her. In the stop position, the latch with its vertical stop surface is in the stop with the door opener trap 1 in the blocking position.

In an alternative reverse mounting the door opener can be mounted door leaf fixed and cooperate with the door latch with a latch arranged on the stationary frame latch or the like accordingly.

The functioning of the door opener in FIG. 1 is as follows:

In the closed position of the door, the door opener latch 1 engages behind the latch. As long as the valve 5 is closed, the locking member 2, that is, the working piston 2 k, against movement in FIG. 1 hydraulically blocked to the right and thus simultaneously also the door opener latch found, ie it is in its so-called. Locking position. She is detected and thus blocked, so she is in the portrayal in FIG. 1 can not turn clockwise. It thus holds the lock catch, not shown, in the stop position. The door can not be opened as long as this blockage by the door opener trap 1 exists.

Only when the valve 5 is opened by electrical actuation, the locking position of the door opener latch 1 is released, ie it comes in the release position. This means that it is released, allowing it to pivot about its pivot axis 1s FIG. 1 can turn clockwise. When the door is opened, the door-opener catch is turned out of position via the latch of the door. During this rotation of the door opener latch 1, the locking member 2, ie the working piston 2k of the hydraulic piston-cylinder device 20 in FIG. 1 moved to the right. The hydraulic medium is thereby moved in the hydraulic circuit so that it flows through the hydraulic line of the open valve 5 and flows into the compensating cylinder 3z, which is acted upon by the return spring 3f hydraulic piston-cylinder device 30. The spring piston 3k is therefore acted upon by compression of the return spring 3f and in FIG. 1 moved to the left.

As soon as the door opener latch 1 comes out of engagement with the latch during the opening process, the return flow of the hydraulic medium takes place under the action of the return spring 3f. The oil reflux can, as long as the valve 5 is opened, flow back through the flow channel of the valve 5. However, when the valve 5 is already closed, the oil return flow through the check valve 4. It opens automatically when pressurized in the return direction, so that the oil return flow can take place through the line of the check valve 4. Under the action of the oil reflux, the working piston 2k of the hydraulic piston-cylinder device 20 is returned to its closed position.

In embodiments in which the door opener latch 1 does not have a separate return device, as shown in FIG FIG. 1 the case remains, the locking member 2, that is, the working piston 2k, during its entire movement during opening and closing in each case permanently in abutment with the door latch 1. When the valve is closed, the blocking of the door latch 1 is against movement in the release direction. In the closed position of the door while the hydraulically blocked locking member 2 is in contact with the door latch 1, which in turn is engaged behind by the latch of the closed door and is in abutment with this.

FIG. 2 shows one opposite FIG. 1 modified version. The modification is that a restoring device 33 is provided, which does not like the rest in FIG. 1 provided hydraulic return device 30 via the hydraulic circuit and the locking element 2 acts on the door latch 1, but acts directly on the door opener trap independently. The restoring device 33 may be a helical compression spring which is supported with its one end on the door opener housing 6 and with its other end on the door opener latch 1.

FIG. 3 shows one opposite FIG. 1 modified embodiment, in which the modification consists in that between the hydraulically actuated locking member 2 and the door latch latch 1, a one-armed lever 2w is connected. In this one-armed lever 2 w is a so-called change, which acts as a transmission between the locking element 2 and the door latch 1.

FIG. 4 shows a comparison with the embodiment in FIG. 3 modified version, wherein the modification consists in that between the hydraulically actuated locking member 2 and the one-armed lever 2w a one-armed latching lever 2s is arranged, which cooperates with the hydraulically actuated locking member 2. The locking lever 2s can be locked and unlocked via the hydraulically actuated blocking element 2.

In the FIGS. 3 and 4 a reset device is not shown. However, the provided restoring device can interact directly with the door opener latch 1, z. B. as in FIG. 2 be performed as a restoring device 33, or acting on the case via the hydraulic locking element 2, z. B. as in FIG. 1 be designed as a hydraulic return device 30.

FIG. 5 shows one opposite the execution in FIG. 2 modified embodiment. The modification is that the hydraulically actuated locking member 2 each of the door latch 1 in the closing direction automatically is tracked and in the tracked position, when the door latch 1 in the closed position of the door is engaged with the lock latch, via the hydraulic valve 5 is detected. This means that the door latch 1 in this embodiment has an automatic self-adjustment. The conventional adjustment of the door latch, in which the adjustment of the door latch on the structural situation of the door during assembly or maintenance of the door opener as a manual adjustment by an adjustment - a so-called. Aufschraubstück - is set manually on the main body of the door latch is no longer necessary with this new system. The reason for this is because the door opener latch 1 is automatically automatically adjustable in the optimum position to lock latch and the determination of the locking member 2 in any arbitrarily tracked position is possible and takes place automatically.

The tracking movement of the door latch 1 occurs in the execution in FIG. 5 is driven by turning the pivotal latch 1 about its pivot axis 1s via the return device 33. In addition, however, the hydraulic locking element 2 can cause not only the tracking of the locking element 2, but also the provision of the door latch 1 under hydraulic loading.

In FIG. 5 In addition, an intermediate stop 11 is provided, which cooperates with the lock latch 1. This intermediate stop 11 may be formed as a memory device that holds the door latch 1 after opening the door in an intermediate position and when closing the door, preferably triggered by the latch, is released, then the automatic adjustment and adjustment of the latch 1, as above described to enable. The return device 33, like the Rückkstelleinrichtung 33 in FIG. 2 be designed as a preloaded mechanical spring device which is acted upon opening the door and then automatically resets the door latch 1 when closing the door. The bias of the return device 33 ensures that it spends the door opener latch 1 in the closed position of the door each up to the stop position to the latch. Additionally or alternatively the restoring device 33 but also have a motor drive with external energy, z. B. an electric motor unit.

FIG. 6 shows a relation to the embodiment in FIG. 5 modified embodiment. The modification consists in that the door opener latch 1 is formed here as a pivoting latch with a pivotable base body 1a and a linearly movable latch body 1b. The pivotable base body 1a cooperates with the hydraulically actuated blocking element 2. The linearly movable case body 1b is acted upon by an actuator 2l to bring the linearly movable door halyard body 1l into engagement with the latch and lock there. The actuating device 21 is connected to the hydraulic circuit of the locking element 2 and is also released via the hydraulic valve 5. This actuator 2l may be connected to a memory device 2m. The actuator 2l may be formed as an automatic spring device or as a power-operated engine unit.

The Figures 7.1 and 7.2 show a relation to the embodiment in FIG. 5 modified embodiment. The modification consists in that the door opener latch 1 is designed here as a positively driven latch via a guide cam 1f.

In this embodiment, a holding device 12 is additionally provided, which locks the door latch 1 after opening the door in the open position, as shown in Figure 7.2 is shown. This lock is then released when closing the door. For this purpose, the holding device 12 on a trigger element 12a, which is confirmed by the latch when closing the door.

The Figures 8.1 and 8.2 show a relation to the embodiment in the Figures 7.1 and 7.2 modified embodiment. The modification is that here the door opener latch 1 is designed as a linearly displaceable latch and the door opener housing 6 a lock latch guide 6a for the latch 90th is provided. When you open the door, the door latch 1 is under the action of the latch 90 up in the in Figure 8.2 shown position. The lock latch guide 6a causes the lock latch 90 finally disengages when the door is opened.

The door opener latch 1 is in the in Figure 8.2 shown position on the holding device 12 and remains in this position as long as the door is open. When the door is closed, the trigger element 12a of the holding device 12 is then actuated via the latch 90 in the sense of a release of the holding device. The door opener trap 1 then moves under the action of the hydraulically actuated locking element 2 down in the in Figure 8.1 illustrated blocking position. When the door is closed, the lock catch 90 engages under the locking edge of the door latch 1 in the optimal engagement due to the made by the locking element 2 continuous tracking and detection.

The Figures 9.1 and 9.2 show a relation to the embodiment in the Figures 8.1 and 8.2 modified embodiment. The modification consists in that here no lock latch guide 6a is provided, but a lock latch actuator 19, which pushes back the latch 90 via a preferably hydraulically actuated plunger during the opening process. The lock latch actuator 19 may be connected to the hydraulic device of the locking device. But it can also be used as a separate motor device, eg. B. be designed as an electric motor.

In the figures 10ff a concrete structural design of an embodiment of a door opener according to the invention is shown in various sectional views. The overall arrangement with the circuit of the components of the door opener is best seen in the schematic diagrams 16a, 16b and 16c.

The door opener, as shown in the sectional views in Figures 10ff, a housing 6, in which the components of the door opener are mounted. The components are components that are used in conjunction with the Embodiments of FIGS. 1 to 9 already described above, namely a door opener latch 1 and a hydraulic locking device with hydraulic circuit, in which, as best seen in the diagrams 16a, 16b and 16c, a locking member 2 with hydraulic piston 2k, a hydraulically acting return device 30, an electrically operable check valve 5 and a check valve are connected.

In the circuit diagrams 16a, 16b and 16c, the components of the door opener are shown. Recognizable is the following:
The piston 2k of the hydraulic piston-cylinder device 20 forms in the illustrated embodiment, the locking member 2, which interacts directly with the door latch 1.

The hydraulic spring storage device 30 consists of a hydraulic compensating cylinder 3z in which a spring piston 3k acted upon by a helical compression spring 3f is guided as a compensating piston. The helical spring 3f forms the return spring, which ensures that the working piston 2k forming the locking member 2 is automatically returned to its blocking position after the door has been opened.

The check valve 4 consists of a 4k acted upon by a helical compression spring 4r locking ball. The check valve 4 is connected between the hydraulic spring storage device 30 and the hydraulic piston-cylinder device 20. The check valve 4 can only be flowed through in one direction, in the FIGS. 16a to 16c from right to left, and thus ensures that the hydraulic fluid in the hydraulic circuit from the piston-cylinder device 20 to the hydraulic spring-loaded device 30 can flow only via the valve 5 and do not reach the hydraulic spring accumulator 30 while bypassing this valve 5 can.

The door opener latch 1 is formed in the illustrated case as a pivotal latch pivotable about its pivot axis 1s. It has a so-called. Aufschraubstück 1j. The Aufschraubstück 1j has in cross-section L-shaped configuration and is on the Basic body of the door opener latch 1 in different position via ribs by means not shown screws lockable, ie adjustable to adjust the door latch 1 to the structural conditions. The adjustment in the adjustment is carried out so that the door opener latch 1 with its Aufschraubstück 1j in the closed position of the door engages behind the latch of the door while rests against the lock latch vibration. In the illustrated case, the door opener latch 1 cooperates with a return spring 33, which is supported directly at its one end to the door latch latch and is supported with its other end in the door opener housing 6. About this return spring 33 ensures that the door opener latch 1 is reset in each case after opening the door back to its closed position in which it is behind with the door closed by the latch case with this in the attack.

In the illustrated case, the check valve 5 has a valve tappet 5v, which is arranged in a cylindrical magnet coil 5s and is rigidly connected to the end face of a plate-shaped magnet armature 5a. The valve lifter 5v is supported on a return spring 5r. The magnetic coil 5s is connected via a switch 57 to a voltage source 58. The valve lifter 5v connected to the armature 5a is drawn into the solenoid coil 5s when the switch 57 is closed. In this case, the return spring 5r is compressed. The valve stem 5v, with its rear end section facing away from the magnet armature 5a, passes through the hydraulic connecting line 56 and has there two through-holes arranged axially one behind the other and perpendicular to the longitudinal axis and crossed by 90 °. A front through-hole 5dv faces the armature 5a, and a rear through-hole 5dh faces the rear end portion. The axial distance between the two through holes corresponds to the working stroke of the valve stem 5v.

In the in Fig. 16a to 16c illustrated case, the check valve 5 is connected as a load current valve, ie the door latch 1 is released when the switch 57 is closed.

When the switch 57 is open, as in Fig. 16a shown, the door opener latch 1 is locked. Although the rear through-hole 5dh is in the plane of the connecting pipe 16, it can not connect the two portions of the connecting pipe 16 adjacent to the valve lifter 5v because its longitudinal axis is not aligned with the longitudinal axis of the connecting pipe 16, as later described in connection with FIG the FIGS. 14a and 15a described in more detail.

When the switch 57 is closed, as in Fig. 16b shown, the valve stem 5v is drawn into the solenoid coil 5s. The front through-hole 5dv engages with the connecting pipe 16 and connects the two portions of the connecting pipe 16 ending on the surface of the valve lifter 5v to each other as described later in connection with FIGS Figures 14b and 15b described in more detail. The check valve 5 is open.

As can be seen in the circuit diagrams 16a, 16b and 16c, when the released door opener latch 1 is pivoted by the latch of the door, the working piston 2k is depressed and the balancing piston 3k is pressurized because of the opened check valve 5. The compensating piston 3k is moved back and compresses the restoring spring 3f acting on the balance piston 3k. Further, acting on the door opener latch 1 return spring 33 is compressed. The return spring 33 which acts on the door opener latch 1 immediately returns the door opener latch 1 to the blocking position as soon as the latch bolt is out of engagement with the door opener latch.

Will now, as in Fig. 16c shown, the switch 57 opened again and thus the check valve 5 is closed, presses the balance piston 3k acting return spring 3f the balance piston 2k in its initial position. As a result of the pressure rise in the connecting line 16 between the balance piston 3k and the check valve 4 now opens the check valve 4, whereby in the connecting line 16 between the check valve 4 and the piston 2k, the pressure rises and the working piston 2k is brought into its initial position. The check valve 4 prevents the acting on the working piston 2 k hydraulic pressure is reduced again. The locking device 2 is locked again.

It can also be provided to dispense with the return spring 33 acting on the door opener latch 1 and to dimension the return spring 3f acting on the compensating piston 3k in such a way that the door latch latch 1 is reset by the power piston 2k.

In the following, the concrete structural design of the embodiment will be explained with reference to the perspective sectional views of Figures 10ff. All components described above are arranged in the substantially cuboid housing 6. For better orientation, an x-y-z coordinate system is drawn in each case.

The hydraulic channels 16 are formed as housing bores of the solid body of the housing 6. Likewise, as housing bores, the receiving spaces of the components are formed in the housing angeodneten components of the door opener. The arrangement of the components is, as the perspective sectional views show complex nested in the smallest space to obtain the most compact design of the door opener. Fig. 10 shows the door opener in a half-section along the xz plane, the section being laid so that the structure of the check valve 5, the working piston 2k and the balance piston 3k of the hydraulic spring device 30 can be seen in a sectional view. According to the in FIG. 10 selected representation form the sides of the housing 6, from which the door opener latch 1 protrudes, the upper end face and the back of the housing. According to this assignment, the check valve 5 and the compensating cylinder 3z are arranged in the lower portion of the housing 11, wherein the longitudinal axes of the two components are arranged parallel to the upper or lower end face of the housing 6.

The working piston 2k is arranged below the door opener latch 1 and engages centrally on the door opener latch 1 (see Fig. 10 ).

The check valve 5 is rotationally symmetrical. The rotationally symmetrical valve body 5k has a cylindrical receiving space for the valve tappet 5v, which is supported on the return spring 5r with its end face facing away from the magnet armature 5a. The return spring 5r is designed as a helical compression spring. Furthermore, the valve body 5k has on its outside a cylindrical receiving space for the magnetic coil 5s. The outer end face of the rigidly connected to the valve stem 5v magnet armature 5a is aligned with the lateral end face of the housing 6. The inner annular end face is at rest, ie in the blocking position of the check valve 5, spaced from the annular end face of the valve body 5k, so that, as As described above, the front through hole 5dv of the valve lifter 5v is not engaged with the connection pipe 16.

The outer end surface of the armature 5a is, as in FIG. 10 recognizable, provided with an arrow-like changeover switch recess 5u, which allows the valve stem 5v by hand by turning about its longitudinal axis from quiescent operation to working flow operation and vice versa is adjusted. Two markings on the housing 6 indicate the rotational position of the valve stem 5v. By turning the valve stem 13v by 90 °, the check valve 5 can be offset from the working current operation in the quiescent current operation. In quiescent operation, the door opener latch 1 is locked when the switch 57 (see Fig. 16a to 16c ) is closed, and released when the switch 57 is open or the power supply is interrupted. It is possible in this way, for example, escape doors to unlock in case of emergency.

Fig. 11 shows a section in the xy plane, now with the back of the door opener facing up. To recognize are now numerous sections of the connecting line 16, which are preferably formed as passage or blind holes, which pass through the surface of the housing 6. The connecting lines 16 are at the pass-through areas with the surface of the Enclosed housing with pressed balls. The check valve 5 is in Fig. 11 not shown in full detail.

The Fig. 13a and 13b show a section in a yz plane, which is defined by the applied to the check valve 5 sections of the connecting line 16. As in Fig. 13a and 13b 1, the valve body 5k has aligned through holes which, when the shut-off valve is open, are aligned with the front through-hole 5dv in the valve tappet 5v and which correspond further to the sections adjoining the check valve 5 (FIG. Fig. 13b). Fig. 13a shows the blocking state of the check valve 5, in which the rear through hole 5dh is in the cutting plane. As already noted above, the show Figures 13a and 13b the check valve 5 in working flow operation.

The Fig. 14a to 15b now clarify the switching of the check valve 5 from the working current operation ( Figs. 14a and 14b ) in the quiescent current operation ( Figs. 15a and 15b ).

In working current operation, the front through-hole 5dv establishes the connection between the sections of the connecting line 16 resting against the check valve 5 as soon as the in Fig. 14a to 15b not shown magnetic coil (see Fig. 16a to 16c ) is flowed through ( Fig. 14b ).

Now, the valve stem 5v is rotated by 90 °, as in Figs. 15a and 15b illustrated, the check valve 5 is in quiescent operation. Now the rear through-hole 5dh establishes the connection between the sections of the connection line 16 resting against the check valve 5, as soon as the magnetic coil is not current-carrying ( Fig. 15a ). If the solenoid is current-flowed, the check valve 5 is locked.
