- the blocking device acts on a movable component of the drive device of the active leaf by having a brake drum coupled to the movable component via a freewheel bearing.
- the brake drum is encompassed by a one-piece brake pad, which is spring-loaded against the brake drum. The pivoting of a spreading element releases the brake pad from the brake drum.
- a generic device is from the DE 10 2009 004 506 A1 known.
- the invention has for its object to provide a device for controlling the closing sequence of a two-leaf revolving door system, the blocking device is compact and easy to adjust in their braking force.
- the blocking device has two brake shoes, which are supported by at least one between the two brake shoes Tension spring against each other are applied to the brake drum.
- the tension spring is supported at one end on one brake shoe and at the other end on a clamping screw screwed into an internal thread of the other brake shoe.
- the tension spring is designed as a helical compression spring.
- the bias of the tension spring is in the simplest way, namely adjustable by turning the clamping screw.
- At least one expansion bolt operatively connected to the mechanical transmission element is arranged between the front ends of the brake shoes, wherein the expansion bolt is arranged on a shaft parallel to its axis of rotation.
- two expansion bolts are provided, wherein the expansion bolts are arranged parallel and spaced from each other and the shank of the clamping screw engages between the expansion bolts, which has a space-saving effect.
- the shank of the clamping screw can have a taper, at least in the region that extends through between the expanding pin, which makes it possible to pivot the shaft carrying the expanding pin.
- the Fig. 1 shows a two-leaf revolving door system 1 with a sweeping walking leaf 2 and a under regardden stationary leaf 3, which are mounted on hinge-like fittings 4 about a respective vertical axis of rotation rotatably mounted on a stationary door frame 5.
- the active leaf 2 and the fixed leaf 3 are each operatively connected to a drive device 6, 7 designed as a revolving door drive, which are mounted in the upper horizontal region of the door frame 5.
- the housings 8, 9 of the drive means 6, 7 are each designed as output shaft 10, 11 formed with vertical axes of rotation output members, wherein the ends of the output shafts 10, 11 protrude from the housings 8, 9 respectively.
- the active leaf 2 and the inactive leaf 3 facing the end of the output shafts 10, 11 each formed as a sliding arm 12, 13 power transmission elements are rotatably mounted.

- the control device may comprise a memory device in which the parameters required for operating the drive devices 6, 7 can be stored non-volatilely.
- a device for regulating the closing sequence has the effect that, when the inactive leaf 3 is not in its closed position, the active leaf 2 can not be moved in the closing direction but remains in the at least partially open position until the inactive leaf 3 has reached its closed position.
- a blocking device 24 is provided, whose arrangement in the drive device 6 of the active leaf 2 in the Fig. 2 is shown.
- the drive means 6 to an electric drive motor 16 the motor shaft 7 on the left side in the drawing with a gear 18 cooperates, which, for example, as shown here, may be formed as a worm-spur gear.
- the transmission 18 interacts with the output shaft 10 of the drive device 6 mounted in a bearing 19 so that a rotational movement of the motor shaft 7 causes a rotational movement of the output shaft 10 that is reduced by the transmission 18.
- a force transmission element 20 cooperates, which engages in a cylinder 22 and is connected there to a spring plate 21.
- a closing spring 23 is supported and thus acts on the force transmission element 20. This causes that at a actuated by the drive motor 16 rotational movement of the output shaft 10 of the drive device 2 in the opening direction, the closing spring 23 is biased. When the energization of the drive motor 16 is terminated, the closing spring 23 then relaxes again and causes via the power transmission element 20 and the gear 18, a rotational movement of the output shaft 10 of the drive device 2 in the closing direction.
- a blocking device 24 is provided on the front side of the drive motor 16 which cooperates with the motor shaft 17 of the drive motor 16.
- the blocking device 24, which is shown in detail in the following figures, has a pivotable one-armed lever 26, which is connected in a coupling point 27 with a transmission element 28.
- the transmission element 28, shown only in sections here, which may be designed as a thrust member, for example as a push rod or Bowden cable, is, like the blocking device 24, a component of the device for controlling the closing sequence and extends to the inactive leaf 3, in particular to one with the inactive leaf 3 motion-coupled component of the drive device 7 of the passive leaf 3.
- the blocking device 24 In the illustrated position of the lever 26, the blocking device 24 in its the movement of the motor shaft 17 blocking state. Reaching the closed position of the inactive leaf 3 leads to a displacement of the transmission element 28 and thus to a pivoting of the lever 26, whereby the blocking device 24 releases the movement of the motor shaft 17 and the active leaf 2 can then be closed by relaxing the closing spring 23.
- Fig. 3 shows a perspective view of the blocking device 24, wherein the drive motor 16, for the sake of clarity here, except the motor shaft 17, not shown.
- a connecting flange 25, which carries a housing 29 of the blocking device 24, serves to connect the blocking device 24 to the drive motor 16.
- the housing 29 has a bearing flange 30, in which the lever 26 is rotatably mounted. Further, the housing 29 laterally recesses 31, which allow access to a not visible in this view clamping screw 45 with a tool.
- the front side, the housing 29 is closed by means of a lid 32 which is screwed to the housing 29.
- a freewheel bearing 34 is arranged, on which a brake drum 35 is mounted.
- the freewheel bearing 34 causes a rotation of the brake drum 35 relative to the shaft end 33 in one direction possible, but locked in the other direction.
- the brake drum 35 is laterally encompassed by two sickle-shaped brake shoes 36, 37, which are mounted in the drawing below by means of bearings 38, 39 pivotally mounted in the housing of the blocking device 24.
- the bearings 38, 39 facing away from the end edges of the brake shoes 36, 37 are spaced above in the drawing, with an expansion bolt 40 engages in this distance, wherein the diameter of the expansion pin 40 is slightly smaller than the distance end edges of the brake shoes 36, 37th This will determined by the degree of wear of the not yet visible in this view brake pads 42, 43 of the brake shoes 36, 37, which abut both shown position of the expansion pin 40 to the brake drum 35.
- the expansion pin 40 is coupled to the lever 26 and arranged parallel to the axis of rotation of the lever 26. A second, on the other side of the axis of rotation the lever 26 mirror-symmetrically arranged expansion bolt 41 is not visible in this view.
- the clamping screw 45 has at both ends, ie both at its screw head 46 and on its threaded shaft 49, a molding for engagement of an adjusting tool, in this embodiment, a slot for engagement of a suitable screwdriver, so that the clamping screw 45 is actuated from both sides to adjust the bias of the tension spring 47.
- the view of this figure also shows that the lever 26 is rotatably connected in the region of its axis of rotation with a shaft 44 which is rotatably mounted in a complementary bush of the bearing flange 30 of the housing 29. In the shaft 44 covering the end of the lever 26, two openings can be seen, within which the upper ends of the two expansion bolts 40, 41 are visible.

- Fig. 9a In the first operating state according to Fig. 9a are the brake pads 42, 43 of the brake shoes 36, 37, as in the previous Fig. 2 to 8 was shown, in its blocking position, that is adjacent to the brake drum 35.
- the two expansion bolts 40, 41 are located in the space between the end edges of the brake shoes 36, 37 without touching them.
- the freewheel bearing 34 of the brake drum 35 causes the motor shaft 17 can indeed rotate in the opening direction of the connected to the drive device 6 active leaf 2, a rotation in the closing direction, however, is locked.
- the lower in the drawing 40 expansion pin is displaced to the left and has the left in the drawing brake shoe 36 correspondingly moved to the left, as with the straight, to the left arrow shown. Since the clamping screw 45 engages with its threaded shaft 49 unchanged in the right brake shoe 47, the tension spring 47 is compressed according to the increase in distance of the end edges of the brake shoes 36, 37. In this operating state, the brake pads 42, 43 of the brake shoes 36, 37 are no longer in contact with the brake drum 35, so that unimpeded rotation of the motor shaft 17 in both directions is possible.

In den Gehäusen 8, 9 der Antriebseinrichtungen 6, 7 sind jeweils als Abtriebswelle 10, 11 mit vertikalen Drehachsen ausgebildete Abtriebsglieder gelagert, wobei die Enden der Abtriebswellen 10, 11 aus den Gehäusen 8, 9 jeweils herausragen. An dem unteren, d.h. dem Gangflügel 2 bzw. dem Standflügel 3 zugewandten Ende der Abtriebswellen 10, 11 sind jeweils als Gleitarm 12, 13 ausgebildete Kraftübertragungselemente drehfest montiert. Das andere Ende des Gleitarms 12, 13 ist jeweils mittels eines Gleiters in jeweils einer im Bereich der oberen horizontalen Kante des Gangflügels 2 bzw. des Standflügels 3 montierten Gleitschiene 14, 15 linear verschiebbar geführt. Eine Drehbewegung der Abtriebswelle 10, 11 der Antriebseinrichtung 6, 7 bewirkt, dass der Gleitarm 12, 13 verschwenkt wird und über den in der Gleitschiene 14, 15 geführten Gleiter den Gangflügel 2 bzw. den Standflügel 3 bewegt.In the
Die Antriebseinrichtungen 6, 7 weisen jeweils eine hier nicht dargestellte Steuerungseinrichtung auf, welche den Bewegungsablauf der Antriebseinrichtungen 6, 7 steuert, z.B. abhängig von Sensorsignalen und/oder manuellen Schalthandlungen.

Prinzipiell ist eine Feststellung der Abtriebswelle 10 der Antriebseinrichtung 6 bei zumindest teilweise geöffneter Position des angeschlossenen Flügels allein durch den Antriebsmotor 16 möglich, indem der Antriebsmotor 16 nach Erreichen dieser Position der Abtriebswelle 10 dauerbestromt bleibt und somit eine die Kraft der Schließerfeder 23 kompensierende Gegenkraft erzeugt. Hierdurch würden jedoch ein hoher Stromverbrauch und gegebenenfalls auch eine störende Geräuschemission durch den stillstehend dauerbestromten Antriebsmotor 16 anfallen.In principle, a determination of the
Um diesen Nachteil zu vermeiden, ist stirnseitig an den Antriebsmotor 16 anschlieĂźend eine Blockiereinrichtung 24 vorgesehen, welche mit der Motorwelle 17 des Antriebsmotors 16 zusammenwirkt. Die Blockiereinrichtung 24, welche in den nachfolgenden Abbildungen noch detailliert dargestellt wird, weist einen schwenkbaren einarmigen Hebel 26 auf, welcher in einem Ankopplungspunkt 27 mit einem Ăśbertragungselement 28 verbunden ist. Das hier nur abschnittsweise dargestellte Ăśbertragungselement 28, welches als Schubglied, beispielsweise als Schubstange oder Bowdenzug ausgebildet sein kann, ist, wie auch die Blockiereinrichtung 24, ein Bestandteil der Vorrichtung zur Regelung der SchlieĂźfolge und erstreckt sich zum StandflĂĽgel 3, insbesondere zu einem mit dem StandflĂĽgel 3 bewegungsgekoppelten Bauteil der Antriebseinrichtung 7 des StandflĂĽgels 3.
