Description

The present invention relates to a closing sequence control for a door having a fixed leaf and a moving leaf.

Closing sequence controls serve to keep the active leaf open in the case of a two-leaf door, as long as the fixed leaf is also open.

The operation of aisle and passive leaf is usually done via a door operator whose power is transmitted via a linkage or a lever on a slider. This slider is again guided in a slide rail. Door operators are in particular door closers, door drives or power door closers to understand. For example, to set the door in its open position, located in the slide locking arrangements for locking and releasing the movement of the slider. In previously known arrangements, the slider is for example a latching connection in the locking arrangement. The release of this latching connection is effected for example by an electromagnetic actuation. All of these holding or locking arrangements include a holding mechanism, which is characterized in that it requires a transmission, because the required holding forces in the available space can not be applied directly via a spring, an electromagnet or the like. These transmissions in turn are costly constructions, which also require a lot of space to achieve the necessary translation. A disadvantage of the previously known arrangements is the complex and expensive construction and the low power / energy density related to the required installation space. However, the current design of door actuators requires very narrow and small slide rails. Furthermore, the corresponding locking arrangement should be accommodated in the slide virtually invisible. Thus, less and less space for the holding or locking mechanism of the slider is available.

It is an object of the present invention to provide a closing sequence control, which allows for cost-effective production and assembly in the smallest space blocking and releasing a slider in a slide rail.

4 a circuit diagram for the closing sequence control according to the invention, wherein the inactive leaf and active leaf are closed.

1 shows a door with a passive leaf 1 and a moving wing 2 in a closed position (top) and an open position (bottom). The passive wing 1 is about a linkage 1.1 with a passive leaf slider 1.2 connected in a slide rail 3 is linearly guided. In the same way is the active leaf 2 over a linkage 2.1 with a moving leaf slider 2.2 connected, which is also in the slide rail 3 is linearly guided. When opening active leaf 2 and peacock 1 move the passive leaf slider 1.2 and the active leaf slider 2.2 away from each other while they are closing the passive leaf 1 and active wings 2 move towards each other as indicated by the respective arrows in 1 shown.

In such a door, it is necessary that when opening first the active leaf 2 and then the inactive leaf 1 swinging open and that when closing first the inactive leaf 1 and then the active leaf 2 is closed. To realize this, a closing sequence control is used, which is initially related to 2 will be explained in detail. Subsequently, the in the 2 to 4 illustrated different states of the two-leaf door explained in more detail. It was in the 2 to 4 the slide rail 3 , in which passive leaf slider 1.2 and active leaf slider 2.2 can move linearly, omitted for reasons of clarity.

According to 2 has the closing sequence control on the inactive side a first fixed-wing cylinder 1.3 and a second inactive cylinder 1.4 on. The first still-wing cylinder 1.3 can by the linear movement of the passive leaf slider 1.2 in the slide rail 3 be actuated while the second inactive cylinder 1.4 the passive leaf slider 1.2 blocked in a first position and released in a second position. For this purpose, the second inactive cylinder 1.4 a movable locking pin on the piston rod of the second inactive cylinder 1.4 can be formed.

In the first position of the second inactive cylinder 1.4 this blocking pin blocks the passive leaf slider 1.2 and lies on a discharge slope of the passive leaf slider 1.2 at. This outlet slope is designed so that by an externally applied force on the passive leaf slider 1.2 , in the release direction, the blocking pin is pressed over the outlet slope in its second position. Thus, by applying a force on the locked passive leaf 1 the passive leaf slider 1.2 over the outlet slope of the actuating pin and thus the second in-flight cylinder 1.4 in its second, the passive leaf slider 1.2 move releasing position.

Between the first inactive cylinder 1.3 and the second inactive cylinder 1.4 is a still-wing fluid line 1.5 intended. This is so to the first inactive cylinder 1.3 and the second inactive cylinder 1.4 connected that upon actuation of the first inactive cylinder 1.3 the second inactive cylinder 1.4 is moved to the first position. This is due to the linear movement of the passive leaf slider 1.2 , which is the first still-wing cylinder 1.3 operated, automatically the second inactive cylinder 1.4 pressed and thus in its first, the passive leaf slider 1.2 Move blocking position.

Furthermore, in the first passive leaf fluid line 1.5 a passive leaf switching element 1.6 optionally, a free fluid flow between the first inactive cylinder 1.3 and the second inactive cylinder 1.4 locks or releases.

The passive leaf switching element 1.6 is designed as a 2/2-way valve and has an electromagnet 1.7 and a valve spring 1.8 on. The valve spring 1.8 is arranged so that the 2/2-way valve is moved by the spring force in that switching position in which a free fluid flow only between the second inactive cylinder 1.4 and the first in-wing cylinder 1.3 , but not vice versa is possible. The electromagnet 1.7 is designed so that it is in the energized state, the 2/2-way valve against the spring force of the valve spring 1.8 holds in a position in which the fluid flow from the second inactive cylinder 1.4 to the first inactive cylinder 1.3 is blocked by the lock function. As a rule, the electromagnet 1.7 be energized, leaving the second inactive cylinder 1.4 is active and the passive leaf slider 1.2 blocked. This condition is in 2 shown.

From the first passive-wing fluid line 1.5 branches - preferably in the region between the first inactive cylinder 1.3 and the passive leaf switching element 1.6 - A second passive leaf fluid line 1.9 starting in a peacock store 1.10 empties. In the second passive leaf fluid line 1.9 is between the branch and the pod memory 1.10 a check valve 4 arranged in the direction of the pinnacle store 1.10 locks. Furthermore, it is parallel to the check valve 4 a pressure relief valve 5 in the second passive leaf fluid line 1.9 arranged.

A similar embodiment, as described above in connection with the inactive side, is also present on the active leaf side.

There, the closing sequence control has a first moving wing cylinder 2.3 and a second active leaf cylinder 2.4 on. The first scroll wing cylinder 2.3 can by the linear movement of the moving leaf slider 2.2 in the slide rail 3 be actuated while the second active leaf cylinder 2.4 the moving leaf slider 2.2 blocked in a first position and released in a second position. For this purpose, the second scroll wing cylinder 2.4 a movable locking pin on the piston rod of the second moving wing cylinder 2.4 can be formed.

In the first position of the second active leaf cylinder 2 .4 this locking pin blocks the active leaf slider 2.2 and lies on an outlet slope of the moving leaf slider 2.2 at. This outlet slope is designed in exactly the same way as the outlet slope on the passive leaf slider 1.2 ,

Between the first scroll-cylinder 2.3 and the second scroll cylinder 2.4 is a walking wing fluid line 2.5 intended. This is so to the first moving wing cylinder 2.3 and the second active leaf cylinder 2.4 connected that upon actuation of the first active leaf cylinder 2.3 the second active leaf cylinder 2.4 is moved to the first position. This is due to the linear movement of the moving leaf slider 2.2 , which is the first active leaf cylinder 2.1 actuated, automatically the second active leaf cylinder 2.4 operated and thus in its first, the active leaf slider 2.2 Move blocking position.

Furthermore, in the first active leaf fluid line 2.5 a moving leaf switching element 2.6 optionally, a free fluid flow between the first scroll cylinder 2.3 and the second scroll cylinder 2.4 locks or releases.

The moving leaf switching element 2.6 , the longitudinally displaceable in the slide rail 3 is mounted, is designed as a 2/2-way valve and has an actuating element 2.7 and a valve spring 2.8 on. The valve spring 1.8 is arranged so that is moved by the spring force, the 2/2-way valve in that switching position in which a free fluid flow only between the first scroll wing cylinder 2.3 and the second scroll cylinder 2.4 but not the other way around.

The first scroll wing cylinder 2.3 is via a second active leaf fluid line 2.9 with a scroll wing memory 2.10 connected. In the second active leaf fluid line 2.9 is a check valve 4 arranged in the direction of the aisle store 2.10 locks. Furthermore, it is parallel to the check valve 4 a pressure relief valve 5 in the second active leaf fluid line 2.9 arranged.

check valve 4 and pressure relief valve 5 work in the same way as described above.

In 2 is shown a condition in which passive wing 1 and active wings 2 are open. The passive leaf slider 1.2 and the active leaf slider 2.2 each act on the first inactive cylinder 1.3 and the first active leaf cylinder 2.3 so that the second inactive cylinder 1.4 and the second scroll wing cylinder 2.4 the passive leaf slider 1.2 or the active leaf slider 2.2 lock. The electromagnet 1.7 is energized and holds the passive leaf switching element 1.6 in a position in which only a fluid flow from the first inactive cylinder 1.3 to the second inactive cylinder 1.4 but not the other way around.

In 3 is shown a state in which the inactive leaf 1 is already closed and now the aisle wing 2 to be closed.

To the passive wing 1 close, the electromagnet 1.7 de-energized switched. Due to the valve spring 1.8 passes the passive leaf switching element 1.6 in a position in which a fluid flow from the second inactive cylinder 1.4 to the first inactive cylinder 1.3 is possible. Will the passive wing 1 now moves, moves simultaneously the passive leaf slider 1.2 to the left in 3 and presses the piston rod into the second passive-leaf cylinder via the outlet bevel 1.4 in from which the fluid due to the position of the passive leaf switching element 1.6 can drain away.

If the passive wing 2 is completely closed - this is in 3 shown - presses the passive leaf slider 1.2 on the actuator 1.7 the active leaf switching element 1.6 and converts this to a position in which a fluid flow from the second scroll wing cylinder 2.4 to the first active leaf cylinder 2.3 is possible. The moving leaf slider 2.2 is anxious to turn right in 3 to wander and presses the piston rod in the second leaf-cylinder 2.4 in from which the fluid due to the position of the active leaf switching element 2.6 can drain away. Now the walking-wing slider becomes 2.2 released and the active leaf 2 can close. This condition is in 4 shown.

Other than described and illustrated, the still-wing memory can 1.10 and the scroll wing memory 2.10 Also be designed as a common memory, with both the first stationary wing fluid line 1.5 as with the second active leaf cylinder 2.3 connected is. In addition, the memory can be completely dispensed with when cylinders are used with volume compensation.

The foregoing description of 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.
