Partition elements according to the prior art.

In the FIG. 1 the process flow of closing an element of a partition according to an embodiment of the invention is shown. After in a first step S1, the element 1 has been started, wherein a drive motor of the element 1, which the element 1 z. B. moves from its parking position to its end position, is supplied with energy, it is checked in a second step S2, whether the element 1 is already in the final position. If this is not the case, the second step S2 is further executed in a "monitoring loop". If the element 1 is in the end position, in a third step S3, the supply voltage of the drive motor of the element 1 is switched to a compression motor, which extends the at least one end profile 5 of the element 1, preferably provided with sealing strips, ie, for example, against the ceiling and soil. In a fourth step S4 it is checked whether the at least one end profile 5 has reached its end position. If this is not the case, the fourth step S4 is executed again in a "monitoring loop". If this is at least one end profile 5 in the end position, the closing of the element 1 ends in a fifth step S5.

Is the monitoring of the end position of the element 1 normally, d. H. without the inventive additional compression of the end profiles, z. B. via a monitoring of the power consumption of the drive motor of the element 1, it needs for the inventive closing of the element 1, d. H. with the pressing of the at least one end profile 5, only a suitable switching of the supply voltage from the drive motor to the injection motor, z. Example, by means of a mechanical end position detector, after which the "normal" control now monitored in step S4 the injection engine and switched off by blocking the motor, increasing power consumption, since then the end position of at least one end profile 5 is reached. This presupposes that either the drive motor of the element 1 and the injection motor in blocking use approximately the same amount of power or the control device is adapted to the power requirements of the injection engine. Of course, the switching can also be achieved differently than by means of a mechanical limit switch for the element 1.

For the above procedure only a power supply with a control or power unit is necessary. The drive motor and the injection motor are thus fed via the same pantographs.

The FIG. 2 shows the procedure of opening an element 1 of a partition wall according to the first preferred embodiment. After, in a sixth step S6, the opening of the element 1 by supplying supply voltage, which has been previously reversed, to the element 1 which is applied to the injection motor is started, it is checked in a seventh step S7 whether the at least one End profile 5 is located in a retracted end position. If this is not the case, then the seventh step S7 is repeated in a "monitoring loop". If this is the case, then in an eighth step S8 the injection motor is switched off and the supply voltage is switched to the drive motor of the element 1 in a ninth step S9. The eighth step S8 and the ninth step S9 can also be summarized. In a tenth step S10 it is checked whether the element 1 of the partition is still running or is already in a parking position. If element 1 still travels, the tenth step S10 is repeated in a "monitoring loop". Does the element 1 no longer, ie the element 1 is in a parking position, for. B. driven to a stop, the drive motor of the element 1 is turned off in an eleventh step S11, before the opening of the partition wall element is terminated in a twelfth step S12.

The FIGS. 3a-3d show a switching device according to the invention, which operates according to an embodiment of the invention according to the invention, ie that according to the in the FIGS. 1 and 2 shown flowcharts. The switching device according to the invention is connected between a first voltage supply terminal 6 of the element 1 and a respective first terminal of the first motor M1 and the second motor M2. The respective second terminals of the first motor M1 and the second motor M2 are connected together and connected to a second voltage supply terminal 7 of the element 1. As previously mentioned, the voltage supply terminals of the element 1 may also be internal voltage terminals of the element 1, e.g. B. if in the element 1, a control device is arranged. In this case, these are the terminals that supply the supply voltage of the first motor M1, that is, the driving motor of the element 1. The switching device is constructed such that a switchable terminal 8 of a change-over switch ES2 is connected to the first power supply terminal 6 is connected, whose first fixed terminal is connected to the first terminal of the drive motor M1 is connected and the second fixed terminal 10 via a diode D1 to the first terminal of the second motor M2, that is, the Verpressmotors is connected. Here, the anode of the diode D1 is connected to the second fixed terminal 10 of the switch ES2 and the cathode of the diode D1 is connected to the first terminal of the injection motor M2. Next, the switching device has a double switch ES1 whose first switching path 11 is connected in parallel to the diode D1 and the second switching path 12 is connected in series with a diode D2 in parallel to the switchable terminal 8 and the first fixed terminal 9 of the switch ES2. Here, the anode of the diode D2 is connected via the second switching path of the double switch ES1 to the first fixed terminal 9 of the switch ES2 and the cathode of the diode D2 connected to the switchable terminal 8 of the switch ES2. Alternatively, the diode D2 can of course also be switched in the same polarity between the second switching path 12 of the double switch ES1 and the first fixed connection 9 of the change-over switch ES2.

The FIG. 3a shows a state of the switch ES2 and the double switch ES1, in which the element 1 is in a parking position, ie in a state as before the in the FIG. 1 shown first step S1 consists. In this state, the switchable terminal 8 of the switch ES2 is connected to the first fixed terminal 9 of the switch ES2, the first switching path 11 of the double switch ES2 open and the second switching path 12 of the double switch ES1 closed. If the element 1 is started, ie in the FIG. 1 1, a voltage is applied to the voltage supply terminals, the first voltage supply terminal 6 receives the positive voltage and the second voltage supply terminal 7 is grounded. In these potential conditions, the diode D2 locks and the drive motor S1 is connected via the switch ES2 between the voltage applied to the second voltage supply terminal 7 ground and the voltage applied to the first voltage supply terminal 6 positive potential, whereby this rotates in a first direction, the element 1 in a closed position the partition moves.

When the end position is reached, the changeover switch ES2 is switched so that the switchable connection 8 is connected to the second fixed connection 10, as shown in FIG FIG. 3b is shown. The potential distribution at the voltage supply terminals remains the same. As a result, the drive motor M1 is no longer at the positive potential, ie it is switched off, and the injection motor M2 is connected via the forward biased diode D1 between the positive potential and ground. As a result, the injection motor M2 rotates in a first direction, so that the at least one end profile 5 is extended and thus the element 1, z. B. against the floor and ceiling, is pressed. As soon as the at least one end profile 5 is no longer in its retracted end position, ie shortly after the start of the injection motor M2, the two switching paths of the double switch ES1 are switched over, ie the first switching path 11 is closed and the second switching path 12 is opened. Once the at least one end profile 5 is extended, that is, the element of the partition is pressed, the voltage supply terminals are no longer supplied with voltage, whereby the injection motor M2 is turned off. This interruption of the supply voltage via a controller, not shown, which is conventionally used as a direct control for the drive motor M1, in which the drive motor M1 directly between the first power supply terminal 6 and the second power supply terminal 7 of the element 1 would be switched. Now that is in the FIG. 1 reached fifth step S5.

The Figure 3c shows the previously described state of the switch ES2 and the double switch ES1 in the in the FIG. 1 shown fifth step S5 or in the in the FIG. 2 shown sixth step S6, ie in a state in which the element 1 of the partition is in the end position and the at least one end profile 5 is pressed. If the element 1 to be opened, ie the in the FIG. 2 6, a positive potential is applied to the first voltage supply terminal ground and to the second voltage supply terminal 7. As a result, the injection motor 2 is between the positive potential and ground, wherein the connection to ground via the switch ES2 and the first switching path 11 of the double switch ES1 takes place. As to that in the FIG. 3b shown reversing the Verpressmotors M2 has taken place, the Verpressmotor M2 now rotates in a second direction, which is opposite to the first direction, whereby the at least one end profile 5 is retracted. Once the at least one retracted end profile 5 is in an end position, the switching paths of the double switch ES1 are switched, ie, the first switching path 11 is opened and the second switching path 12 is closed, as in the 3d figure is shown. As a result, the injection motor M2 is switched off, since the diode D1 lying parallel to the first switching path 11 of the double switch ES1 blocks at this potential distribution. Further, the drive motor M1 is thereby turned on, since the diode D2 is at this potential distribution in the forward direction. The drive motor M1 is in terms of in the FIG. 3a reversed state shown, whereby it runs in a direction opposite to the first direction of rotation second direction of rotation and thus the element 1 of the partition from the end position in a Park position moves when it reaches the switch ES2 switched and then, for. B. due to the increased power consumption of the drive motor M2, which is switched off at the voltage supply terminals supply voltage. Now that is in the FIG. 2 achieved twelfth step S12 and the switch and the double switch of the switching device are again in the in the FIG. 3a shown state.

By appropriate control, a partition wall element 1 can also be in an end position before it approaches another partition wall element 1 or another stop, d. H. the change-over switch ES2 can be switched differently. Also, the at least one end profile 5 need not necessarily or exclusively press against the floor and ceiling, of course, a pressing in the horizontal direction is possible.

The FIG. 4 shows a method for controlling a partition wall element 1 according to a second preferred embodiment of the invention. In a thirteenth step S13, the partition wall element 1 is started by applying a supply voltage. In a fourteenth step S14 it is checked whether the end profile 5, which is provided in all embodiments of the invention, preferably with a sealing lip, in an open end position, that is completely retracted. If this is not the case, ie, the partition wall element 1 is pressed, then in a fifteenth step S15, the end profile 5 is retracted, ie the compression canceled, so z. B. ascended a sealing strip, after which again the fourteenth step S14 is executed, in which it is checked whether the end profile 5 is fully retracted, ie no more compression exists, so z. B. a sealing strip is completely open. If this is the case, then in a sixteenth step S16 of the injection engine M2 is stopped and it is checked in a seventeenth step S17, whether the partition wall element 1 is to drive up or drive, that is, for example, to be brought into the parking position or the end position. If the element 1 is to drive up, ie to be brought into the parking position, for example, the drive motor M1 of the element 1 is energized in an eighteenth step S18 by the switching device so that the element 1 moves in the upward direction, ie in the direction of the parking position. In a subsequent nineteenth step S19 it is checked whether the partition wall element 1 is in the desired position, for. B. in the park position, ie in the end position "open". If this is not the case, step S18 is again executed. If this is the case, then in a twentieth step S20 the drive motor M1 is switched off. However, the partition element should not be ascended, but z. B. are moved from the parking position to an end position, a twenty-first step S21 is performed after the seventeenth step S17, in which the partition wall element 1 is lowered by a corresponding drive in the direction to. After the twenty-first step S21, it is checked in a twenty-second step S22 whether the partition wall element 1 is in an end position, ie, for example, in an end position "closed". If this is not the case, then the twenty-first step S21 is executed again, that is, the partition wall element 1 continues to move in the direction to. If this is the case, the twentieth step S20 is performed and the drive motor shuts off.

After the drive motor M1 has been switched off in the twentieth step S20, the injection motor M2 is controlled by the switching device according to the invention in a twenty-third step S23 so that the at least one end profile 5 approaches, ie the partition wall element 1 is compressed. In a subsequent twenty-fourth step S24, it is checked whether the at least one end profile 5 is complete is extended. If this is not the case, step S23 is again carried out. If this is the case, then in a subsequent step S25 the injection motor M2 is switched off, after which the method is ended with a twenty-sixth step S26.

In contrast to the first preferred embodiment of the invention, the partition wall element 1 according to the second preferred embodiment of the invention is thus always pressed in the standing state, d. H. also z. B. in the parking position.

The foregoing description of the embodiments according to the present invention is for illustrative purposes only, and not for the purpose of limiting the invention. Various changes and modifications are possible within the scope of the invention without departing from the scope of the invention and its equivalents.
