Description

The present invention relates to a closing sequence control for a two-leaf, a fixed wing and a power wing door having their leaves by a respective on the hinge opposite side of the door on the fixed leaf and the active leaf mounted overhead door closer are movable, each overhead door closer having a closer shaft, with the one End of a pivot arm is connected, which is guided longitudinally displaceably with its other end via a slider in a frame-fixed guide rail, and the active leaf associated slider is connected to a mounted in the guide rail clamping rod, which is acted upon by a clamping element, which in the closed position of Inactive leaf held by a triggering element in a release position and in an opening movement of the passive leaf of the triggering element can be converted into a blocking position.

Such closing sequence arrangements are known in principle. They ensure that the inactive leaf is closed in front of the active leaf, thus ensuring complete, tight closing of the door. The correct closing sequence can be achieved, for example, by a push-rod clamping determination. The active leaf is freely movable when the inactive leaf is closed. However, if both door leaves are opened, the active leaf is kept open via the closing sequence control until the inactive leaf is completely closed.

This known closing sequence control has proven itself wherever there is a band-side mounting of the door closer, in which the door hinges are arranged on the same door side, as well as the door closer, the guide rail and the closing sequence control.

However, if the door hinges are on the opposite side of the door closer, the guide rail and the closing sequence control in double-leaf doors, due to the geometric conditions, the sliders on the pivot arms of the door closer at an opening movement of the door initially move slightly in the lock direction and only then in the direction the hinge side of the door leaves. This could lead to jamming of the known closing sequence control, so that the desired operation is not always reliably achieved.

It is therefore an object of the present invention to design a closing sequence control of the type mentioned above in such a way that the door hinges of the door leaves can be arranged on the side facing away from the door closers, the guide rail and the closing sequence control, wherein without electrical, hydraulic or pneumatic control a secure closing sequence control can be guaranteed.

This object is achieved by a closing sequence control for a two-leaf, a fixed wing and a power wing door, the door leaves of each one on the hinge opposite side of the door on the inactive leaf and the active leaf mounted overhead door closer are movable, each overhead door closer having a closer shaft, with the one End of a pivot arm is connected, which is guided longitudinally displaceably with its other end via a slider in a frame-fixed guide rail, and the active leaf associated slider with a mounted in the guide rail Clamping rod is connected, which is acted upon by a clamping element which is held in the closed position of the inactive leaf by a triggering element in a release position and in an opening movement of the inactive leaf from the trigger element into a blocking position, according to the invention achieved in that the triggering element with a two-armed lever is in operative connection, which is acted upon by the closer shaft of the attached to the fixed leaf overhead door closer so that the triggering element transfers the blocking element in its release position.

Instead of being acted upon by the closer shaft, it is also possible to act on the end of the pivot arm connected to the closer shaft.

As a result of this configuration, a closing sequence control can be provided by simple means, in which a slight movement of the slider in the lock direction is insignificant, so that the desired operation can be reliably guaranteed.

The dependent claims have advantageous developments of the invention to the content.

According to an advantageous development of the two-armed lever is held on a bearing block, which is arranged on the guide rail.

The bracket is advantageously formed as a U-shaped angle, the open side facing the overhead door closer.

The two-armed lever is according to a preferred embodiment on the end face of the one leg of the U-shaped angle pivotally stored. In the other leg of the U-shaped angle, a bearing bore is advantageously arranged, in which the trigger element is guided displaceably.

The triggering element has, according to a preferred development, a substantially right-angled arm, which is arranged between the legs of the U-shaped bearing block and projects beyond this.

The arm is advantageously acted upon at its protruding end of the two-armed lever.

According to an advantageous embodiment of the arm is provided at its over the legs of the U-shaped bearing block projecting end with a pin-shaped approach.

The two arms of the two-armed lever are advantageously arranged at an angle to each other, preferably at an angle between about 90 ° to 180 °.

The one arm of the two-armed lever is according to a preferred embodiment of the pin-shaped projection, while the other arms of the two-armed lever is acted upon by the closer shaft.

In the following description and in the figures, the door, the door closer and the closing sequence control is explained and illustrated only in the context of interest here. In particular, arranged in the guide rail elements of the closing sequence control are not treated here, but assumed to be known.

FIG. 1 shows a two-leaf, a passive leaf 1 and a leaf 2 having door. In the upper region of the inactive leaf 1 and the active leaf 2, a top door closer 3 and a closing sequence control 4 are each arranged on the hinge opposite side.

Each overhead door closer 4 has a closer shaft 5, which is connected to one end of a pivot arm 6, which is guided with its other end via a slider in a frame-fixed guide rail 7 longitudinally displaceable. The sliding leaf 2 associated slider is connected to a mounted in the guide rail 7 clamping rod, which is acted upon by a clamping element. The clamping element is held in the closed position of the inactive leaf 1 by a triggering element 8 in a release position and can in an opening movement of the inactive leaf 1 of the trigger element 8 in a Locking position can be transferred, in which the active leaf 2 is fixed.

The triggering element 8 is formed in the present as a rod and extends between the two guide rails 7. The triggering element 8 is mounted in the region of the inactive leaf 1 in a bearing block 9, which is arranged on the vane-side guide rail 7.

The bearing block 9 is formed as a U-shaped angle, the open side of the overhead door closer 3 faces. In the one leg of the U-shaped angle, a bearing bore 10 is arranged, in which the trigger element 8 is guided displaceably. On the front side of the other leg of the U-shaped angle, a two-armed lever 11 is pivotally mounted, which is in operative connection with the trigger element 8.

The triggering element 8 has a substantially perpendicular projecting arm 12 which is disposed between the legs of the U-shaped bearing block 9 and projects beyond this. At the over the legs of the U-shaped bearing block 9 projecting end of the arm 12 is provided with a pin-shaped projection 13 which rests against the two-armed lever 11.

The two arms of the two-armed lever 11 are arranged at an angle to each other and include, for example, an angle between 90 ° and 180 °.

The arrangement is such that one arm of the two-armed lever 11 rests against the pin-shaped projection 13 and the other arm can be acted upon by the closer shaft 5 of the standing-leaf-side overhead door closer 3.

• Bei geschlossenem Standflügel 1 kann der Gangflügel 2 frei geöffnet und geschlossen werden. In diesem Zustand liegt der zweiarmige Hebel 11 an der Schließerwelle 5 bzw. an dem mit der Schließerwelle 5 verbundene Ende des Schwenkarms 6 an. Sobald aber der Standflügel 1 geöffnet wird, entfernt sich der zweiarmige Hebel 11 von der Schließerwelle 5,
• wodurch die Schließfolgeregelung aktiviert und der Gangflügel 2 in einer geöffneten Stellung gehalten wird. In geöffnetem Zustand des Standflügels 1 besteht somit kein Kontakt zwischen dem zweiarmigen Hebel 11 und der zugehörigen Schließerwelle 5. Erst wenn der Standflügel 1 in seine vollständig geschlossene Endlage kommt, gelangt der zweiarmige Hebel 11 wieder in Kontakt mit der Schließerwelle 5 bzw. mit dem mit der Schließerwelle 5 verbundene Ende des Schwenkarms 6. Dadurch wird der zweiarmige Hebel 11 in Richtung auf den stiftförmigen Ansatz 13 verschwenkt, und der Ansatz 13, der Arm 12 und das Auslöseelement 8 werden nach links (in den Figuren) verschoben. Dadurch wird der Gangflügel 2 wieder freigegeben und kann nun von dem Obentürschließer 3 geschlossen werden.

The closing sequence control works as follows:

• When the inactive leaf 1 is closed, the active leaf 2 can be freely opened and closed. In this state, the two-armed lever 11 abuts on the closer shaft 5 and on the end of the swing arm 6 connected to the closer shaft 5. But as soon as the inactive leaf 1 is opened, the two-armed lever 11 moves away from the closer shaft 5,
• whereby the closing sequence control is activated and the active leaf 2 is held in an open position. In the open state of the inactive leaf 1, there is thus no contact between the two-armed lever 11 and the associated closer shaft 5. Only when the inactive leaf 1 comes into its completely closed end position, the two-armed lever 11 again comes into contact with the closer shaft 5 or with the Thus, the two-armed lever 11 is pivoted in the direction of the pin-shaped projection 13, and the projection 13, the arm 12 and the trigger element 8 are moved to the left (in the figures). As a result, the active leaf 2 is released again and can now be closed by the overhead door closer 3.

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.
