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 prior art arrangements is the complex and costly construction and related to the required space low power / energy density. 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.

FIG. 1 shows a door with a passive leaf 1 and a moving leaf 2 in a closed position (above) and an open position (below). The inactive leaf 1 is connected via a linkage 1.1 with a passive leaf slider 1.2, which is linearly guided in a slide rail 3. In the same way, the active leaf 2 is connected via a linkage 2.1 with a moving leaf slider 2.2, which is also guided linearly in the slide rail 3. When opening the active leaf 2 and fixed leaf 1, the passive leaf slide 1.2 and the active leaf slide 2.2 move away from each other while they move towards each other when closing the passive leaf 1 and the leaf 2, as indicated by the respective arrows in FIG. 1 shown.

In such a door, it is necessary that when opening first the active leaf 2 and then the inactive leaf 1 swings 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 FIG. 2 will be explained in detail. Subsequently, the in the FIGS. 2 to 4 illustrated different states of the two-leaf door explained in more detail. It was in the FIGS. 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 the sake of clarity.

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

In the first position of the second inactive cylinder 1.4, this blocking pin blocks the inactive leaf slider 1.2 and abuts against an outflow slope of the passive leaf slider 1.2. This outlet slope is formed so that is pressed by an externally applied force on the passive leaf slider 1.2, in the release direction, the blocking pin on the outlet slope in its second position. Thus, by applying a force on the blocked fixed leaf 1, the passive leaf slider 1.2 on the outlet slope of the actuating pin and thus the second inactive cylinder -1.4 process in its second, the passive leaf slider 1.2 releasing position.

Between the first inactive cylinder 1.3 and the second inactive cylinder 1.4, a still-wing fluid line 1.5 is provided. The latter is connected to the first inactive cylinder 1.3 and the second inactive cylinder 1.4 in such a way that, when the first inactive cylinder 1.3 is actuated, the second inactive cylinder 1.4 is moved into the first position. As a result, by the linear movement of the fixed leaf slider 1.2, which actuates the first inactive cylinder 1.3, automatically actuated the second inactive cylinder 1.4 and thus moved into its first, the passive leaf slider 1.2 blocking position.

Furthermore, in the first still-wing fluid line 1.5 a passive leaf switching element 1.6 is arranged, which optionally has 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. 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 inactive cylinder 1.3, but not vice versa possible. The electromagnet 1.7 is designed such that, in the energized state, it holds the 2/2-way valve counter to the spring force of the valve spring 1.8 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 blocking function , As a rule, the electromagnet 1.7 will be energized, so that the second inactive cylinder 1.4 is active and blocks the passive leaf slider 1.2. This condition is in FIG. 2 shown.

From the first passive-edge fluid line 1.5 branches off - preferably in the region between the first inactive cylinder 1.3 and the passive leaf switching element 1.6 - from a second passive-fluid conduit 1.9, which opens into a passive-store 1.10. In the second passive leaf fluid line 1.9, a check valve 4 is arranged between the branch and the passive leaf store 1.10, which blocks in the direction of the passive leaf store 1.10. Furthermore, parallel to the check valve 4, a pressure relief valve 5 is arranged in the second passive leaf fluid line 1.9.

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 active leaf cylinder 2.3 and a second active leaf cylinder 2.4. The first active leaf cylinder 2.3 can be actuated by the linear movement of the active leaf slider 2.2 in the slide rail 3, while the second active leaf cylinder 2.4 blocks the active leaf slide 2.2 in a first position and releases it in a second position. For this purpose, the second moving-wing cylinder 2.4 has a movable blocking pin, which may be formed by the piston rod of the second moving-wing cylinder 2.4.

In the first position of the second active leaf cylinder 2.4, this blocking pin blocks the active leaf sliding piece 2.2 and in doing so bears against an outlet slope of the active leaf sliding piece 2.2. This discharge chute is designed in the same way as the chute on the passive leaf slide 1.2.

Between the first moving-wing cylinder 2.3 and the second moving-wing cylinder 2.4, a moving-wing fluid line 2.5 is provided. This is connected to the first active leaf cylinder 2.3 and the second active leaf cylinder 2.4 such that upon actuation of the first active leaf cylinder 2.3, the second leaf active cylinder 2.4 is moved to the first position. As a result, the second active leaf cylinder 2.4 is automatically actuated by the linear movement of the moving leaf slider 2.2, which actuates the first active leaf cylinder 2.1, and thus moved into its first, the active leaf slider 2.2 blocking position.

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

The active leaf switching element 2.6, which is mounted longitudinally displaceable in the slide rail 3, is designed as a 2/2-way valve and has an actuating element 2.7 and a valve spring 2.8. 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 first active leaf cylinder 2.3 and the second active leaf cylinder 2.4, but not vice versa possible.

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

Check valve 4 and pressure relief valve 5 work in the same manner as already described above.

In FIG. 2 is shown a state in which passive leaf 1 and active leaf 2 are open. The passive leaf slide 1.2 and the active leaf slide 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 inactive cylinder 2.4, the passive leaf slider 1.2 or the Gate 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 one Fluid flow from the first inactive cylinder 1.3 to the second passive-wing cylinder 1.4, but not vice versa is possible.

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

To close the inactive leaf 1, the electromagnet 1.7 is de-energized. As a result of the valve spring 1.8, the inactive leaf switching element 1.6 reaches a position in which a fluid flow from the second inactive cylinder 1.4 to the first inactive cylinder 1.3 is possible. If the inactive leaf 1 is now moved, at the same time the passive leaf slide 1.2 moves to the left in FIG FIG. 3 and presses on the outlet slope of the piston rod in the second inactive cylinder 1.4 into which the fluid can flow due to the position of the passive leaf switching element 1.6.

When the inactive leaf 2 is completely closed - this is in FIG. 3 shown - pushes the passive leaf slider 1.2 on the actuator 1.7 of the active leaf switching element 1.6 and converts this into a position in which a fluid flow from the second leaf valve cylinder 2.4 to the first leaf active cylinder 2.3 is possible. The active leaf slider 2.2 strives to move right in FIG. 3 to wander and presses the piston rod into the second active leaf cylinder 2.4, from which the fluid can flow due to the position of the active leaf switching element 2.6. Now, the active leaf slider 2.2 is released and the active leaf 2 can close. This condition is in FIG. 4 shown.

Other than described and illustrated, the still-leaf memory 1.10 and the scroll-memory 2.10 may also be formed as a common memory, which is connected to both the first stationary-wing fluid line 1.5 and the second active-wing cylinder 2.3. 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.
