Description

Schubstangenverschluß für eine an einem Schaltschrank-Korpus angelenkte SchranktürePush rod lock for a cabinet door hinged to a control cabinet body
Die Erfindung betrifft einen Schubstangenverschluß für eine an einem Schalt- schrank-Korpus angelenkte Schranktüre mit einer Verriegelungsmechanik, die ein in Drehrichtung versetzbares Betätigungsglied aufweist, welches mit einer Schubeinheit gekoppelt ist, wobei die Schubeinheit ein quer zur Schubrichtung von der Rotationsachse des Betätigungsgliedes beabstandetes Stellglied aufweist, welches mittels des Betätigungsgliedes antreibbar ist.The invention relates to a push rod lock for a cabinet door articulated on a control cabinet body with a locking mechanism which has an actuating element which can be displaced in the direction of rotation and which is coupled to a pushing unit, the pushing unit having an actuator which is spaced transversely to the pushing direction from the axis of rotation of the actuating element , which can be driven by the actuator.
Ein solcher Schubstangenverschluß ist aus der DE 90 10 1 75 U1 bekannt. Hierbei ist auf der Innenseite einer Schranktür eine Verriegeiungsmechanik in Form eines Getriebegehäuses aufgesetzt. In dem Getriebegehäuse ist ein Ritzel drehbar untergebracht, das mit einer Handhabe verdreht werden kann, in dem Ge- triebegehäuse ist auch die Schubeinheit geführt. Sie wird von zwei Zahnstangen gebildet, die sich mit ihren Zahnungen diametral gegenüberstehen und beide mit dem Ritzel kämmen. An die Zahnstangen sind für die Verriegelung der Schranktür dienende Schubstangen angekoppelt. Bei einer Drehung der an der Vorderseite der Schranktür angeordneten Handhabe werden die Zahnstangen gegenläufig verschoben. Eine Drehung im Uhrzeigersinn veranlaßt die Öffnung, gegen den Uhrzeigersinn wird Schließung der Schranktür bewirkt. Bei einem Wechsel der Anschlagart der Schranktür wird diese um 180° gedreht. Damit wird aber auch der Drehsinn der Handhabe gewechselt (Drehung im Uhrzeigersinn bewirkt nun die Schließung). Dies ist aber aus Gründen des Bedienkomforts unerwünscht.Such a push rod lock is known from DE 90 10 1 75 U1. In this case, a locking mechanism in the form of a gear housing is placed on the inside of a cabinet door. A pinion is rotatably accommodated in the gear housing, which can be turned with a handle, in which gear drive housing is also guided the thrust unit. It is formed by two racks, which are diametrically opposed with their teeth and both mesh with the pinion. Push rods serving to lock the cabinet door are coupled to the racks. When the handle on the front of the cabinet door is rotated, the racks are moved in opposite directions. A clockwise rotation causes the opening, counterclockwise the cabinet door is closed. When changing the way the cabinet door is hinged, it is turned by 180 °. This also changes the direction of rotation of the handle (clockwise rotation now causes the closure). However, this is undesirable for ease of use.
Zur Umgehung dieses Nachteils ist es in der EP 0 261 266 B1 vorgeschlagen, beim Wechsel der Anschlagart sowohl die Handhabe als auch die Verriegelungsmechanik umzubauen. Mit diesem Umbau kann dann der Drehsinn beibehalten werden. Jedoch ist für eine solche Maßnahme ein großer Aufwand notwendig. Darüberhinaus ist es aufgrund von Platzverhältnissen häufig gefordert, zur Verriegelung die Handhabe wahlweise im oder gegen den Uhrzeigersinn, bei vorgegebener Anschlagart der Schranktür drehen zu können. Hierzu ist jedoch die Verwendung zweier unterschiedlicher Verschlüsse vorgesehen.To avoid this disadvantage, it is proposed in EP 0 261 266 B1 to convert both the handle and the locking mechanism when changing the stop type. With this modification, the direction of rotation can then be maintained. However, a great deal of effort is required for such a measure. In addition, due to space constraints, it is often required to be able to turn the handle either clockwise or counterclockwise for locking purposes, with the cabinet door being locked in place. However, the use of two different closures is intended for this purpose.
Es ist Aufgabe der Erfindung, einen Schubstaπgenverschluß der eingangs erwähnten Art zu schaffen, der für unterschiedliche Anforderungen verwendbar ist und einen hohen Bedienkomfort aufweist.It is an object of the invention to provide a push rod lock of the type mentioned at the outset, which can be used for different requirements and is very easy to use.
Diese Aufgabe der Erfindung wird dadurch gelöst, daß das Stellglied dem Betätigungsglied in verschiedenen Montagepositionen zuordenbar ist, wobei in den gewechselten Montagepositionen die Schubrichtung der Schubeinheit bei- behalten, jedoch die Drehrichtung des Betätigungsgliedes gewechselt ist, und/oder wobei in den gewechselten Montagepositionen die Schubrichtung der Schubeinheit gewechselt, jedoch die Drehrichtung des Betätigungsgliedes beibehalten ist.This object of the invention is achieved in that the actuator can be assigned to the actuating element in different assembly positions, the pushing direction of the push unit being in the changed assembly positions. retained, however, the direction of rotation of the actuator is changed, and / or wherein in the changed mounting positions, the direction of thrust of the thrust unit is changed, but the direction of rotation of the actuator is maintained.
Erfindungsgemäß wird mit dem Schubstangenverschluß ein Beschlag zur Verfügung gestellt, der infolge einfacher Umbaumaßnahmen eine Variabilität der Schließstellungen ermöglicht. Abhängig von der Zuordnung des Stellgliedes zu dem Betätigungsglied können die Schubrichtung der Schubeinheit und der Drehsinn des Betätigungsgiiedes unabhängig voneinander eingestellt werden.According to the invention, a fitting is made available with the push rod lock, which allows a variability of the closed positions due to simple conversion measures. Depending on the assignment of the actuator to the actuator, the direction of thrust of the thrust unit and the direction of rotation of the actuator can be adjusted independently.
Eine platzsparende Bauweise ist dann möglich, wenn vorgesehen ist, daß die Schubeinheit plattenartig ausgebildet ist und flach vorderseitig auf der Schranktüre aufgebracht ist. Insbesondere wird die Rückseite der Schranktüre von Bauteilen des Schubstangenverschlusses freigehalten, wodurch beengten Platzverhältnissen insbesondere im Randbereich der Schranktüre Rechnung getragen werden kann.A space-saving design is possible if it is provided that the pusher unit is plate-like and is mounted flat on the front of the cabinet door. In particular, the rear of the cabinet door is kept free of components of the push rod lock, as a result of which limited space, particularly in the edge region of the cabinet door, can be taken into account.
Eine mögliche Erfindungsvariante ist dadurch gekennzeichnet, daß das Betätigungsglied als Ritzel ausgebildet ist, dessen Zähne mit dem als Zahnung ausgebildeten Stellglied zusammenarbeiten.A possible variant of the invention is characterized in that the actuating member is designed as a pinion, the teeth of which cooperate with the actuator designed as toothing.
Dabei kann es insbesondere vorgesehen sein, daß das zahnstangenförmige Stellglied in Schubrichtung gesehen wahlweise links- oder rechtsseitig mit dem Ritzel in Eingriff bringbar ist.In particular, it can be provided that the rack-shaped actuator can be brought into engagement with the pinion on the left or right side, as seen in the direction of thrust.
Denkbar ist es auch, daß der den Vorschub bewirkende Teil des zahnstangen- förmigen Stellgliedes quer zur Schubrichtung gesehen wahlweise links- oder rechtsseitig des Ritzels angeordnet ist. Mit diesen einfachen Maßnahmen läßt sich der Drehsinn des Betätigungsgliedes bzw. die Schubrichtung der Schubeinheit einstellen.It is also conceivable that the part of the rack-shaped actuator which causes the feed, as seen transversely to the direction of thrust, can optionally be left or right is arranged on the right side of the pinion. With these simple measures, the direction of rotation of the actuator or the direction of thrust of the thrust unit can be adjusted.
Nach einer bevorzugten Ausgestaltung der Erfindung ist es vorgesehen, daß die Schubeinheit mit einer Ausbrechung versehen ist, in der das Betätigungsglied untergebracht ist, daß die Schubeinheit an eine Schubstange der Verriegelungsmechanik angekoppelt ist und daß die Befestigungsstellen, an denen die Schubeinheit mit der Schubstange verbunden ist und der Drehpunkt des Befestigungsgliedes auf einer in Schubrichtung verlaufenden Linie angeordnet sind. Infolge dieser Symmetrieausbildung kann die Schubeiπheit dem Betätigungsglied in verschiedenen Montagepositionen zugeordnet werden.According to a preferred embodiment of the invention, it is provided that the push unit is provided with a cutout in which the actuator is housed, that the push unit is coupled to a push rod of the locking mechanism and that the fastening points at which the push unit is connected to the push rod and the pivot point of the fastener are arranged on a line extending in the direction of thrust. As a result of this formation of symmetry, the pushing unit can be assigned to the actuating element in various assembly positions.
Ein einfacher Aufbau läßt sich mit wenigen Teilen dann verwirklichen, wenn vorgesehen ist, daß die Schubeinheit mit einem Gehäuse in Schubrichtung verstellbar gehalten ist, daß das Gehäuse einen Rotationskörper drehbar lagert, und daß das Betätigungsglied unverdrehbar an dem Rotationskörper gehalten ist.A simple construction can be realized with a few parts if it is provided that the thrust unit is held adjustable with a housing in the thrust direction, that the housing rotatably supports a rotating body, and that the actuating member is held non-rotatably on the rotating body.
Dabei ist es denkbar, daß das Gehäuse die Schubeinheit, den Rotationskörper und das Betätigungsglied zu einer vormontierten Baueinheit zusammengeschlossen sind, die an der Schranktür befestigbar ist, und daß die Schubeinheit über Koppelelemente an die Schubstange der Verriegelungsmechaπik anbringbar ist.It is conceivable that the housing, the thrust unit, the rotary body and the actuator are combined to form a preassembled unit that can be attached to the cabinet door, and that the thrust unit can be attached to the push rod of the locking mechanism via coupling elements.
Bevorzugt ist die Schubeinheit an der Vorderseite und die Schubstange auf der Rückseite der Schranktür angeordnet. Durch einen Durchbruch der Schranktür hindurch steht die Schubeinheit mit der Schubstange dann in Wirkverbindung. Die Erfindung wird im folgenden anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:The push unit is preferably arranged on the front and the push rod on the back of the cabinet door. Through an opening in the cabinet door, the push unit is then operatively connected to the push rod. The invention is explained in more detail below with reference to exemplary embodiments shown in the drawings. Show it:

Die Schranktüre 60 weist ein ebenes Türblatt 61 auf, das an seinem Rand mit Abkantungen 62 versehen ist. Im Abkantungsbereich läßt sich innen an der Schranktüre eine Schubstange 63 anbringen. Die Schubstange ist als Winkelblech ausgebildet und liegt an dem Türblatt 61 und der Abkantung 62 an.In Fig. 1, a push rod lock according to the invention is shown in more detail. This push rod lock can be attached to a cabinet door 60 at the front. The cabinet door 60 has a flat door leaf 61 which is provided with bevels 62 on its edge. A push rod 63 can be attached to the inside of the cabinet door in the bent area. The push rod is designed as an angled plate and lies against the door leaf 61 and the bevel 62.
Der Schubstangenverschluß weist ein Gehäuse 10 auf, das mit einer Aufnahme 13 versehen ist. Die Aufnahme 13 ist als rechteckförmige Aussparung in dem dem Türblatt 61 zugekehrten Bereich des Gehäuses eingearbeitet. Von der Vorderseite des Gehäuses 10 her erhält man zu der Aufnahme 1 3 Zugang durch eine Lagerung 1 1 , die als Bohrung ausgeführt ist. Die Bohrungsachse steht dabei senkrecht zu dem Türblatt 61 . In der Lagerung 1 1 kann ein Rotationskörper 30 gelagert werden. Hierzu besitzt der Rotationskörper 30 einen zylindrischen Lagerzapfen 31 . An den Lagerzapfen 31 ist ein Steckansatz 32 angebunden. Der Steckansatz 32 weist zwei diametral gegenüberliegende Ausnehmungen 33 auf. An diesen kann ein Betätigungsglied 40 mittels Ansätzen 41 festgelegt werden. Das Betätigungsglied 40 ist vorliegend als Ritzel ausgebildet. Es weist eine zentrische Steckaufnahme auf, mittels derer es auf dem Steckansatz 32 aufgeschoben werden kann. Um das Ritzel zu sichern, ist eine Gewindeaufnahme 34 stirnseitig in den Steckansatz 32 eingearbeitet.The push rod lock has a housing 10 which is provided with a receptacle 13. The receptacle 13 is incorporated as a rectangular recess in the area of the housing facing the door leaf 61. From the front of the housing 10, one receives access to the receptacle 1 3 through a bearing 1 1 which is designed as a bore. The bore axis is perpendicular to the door leaf 61. In the storage 1 1, a rotary body 30 can be stored. For this purpose, the rotating body 30 has a cylindrical bearing journal 31. A plug-in projection 32 is connected to the bearing journal 31. The plug-in projection 32 has two diametrically opposite recesses 33. An actuator 40 can be attached to this by means of lugs 41. In the present case, the actuator 40 is designed as a pinion. It has a central plug-in receptacle, by means of which it can be pushed onto the plug-in attachment 32. In order to secure the pinion, a thread receptacle 34 is incorporated into the front end of the plug-in attachment 32.
In die Aufnahme 1 3 des Gehäuses 10 kann eine Schubeinheit 20 eingelegt werden. Die Schubeinheit 20 ist plattenförmig ausgebildet. Bezüglich ihrer Breite ist sie auf die Breite der Aufnahme 13 angepaßt ausgebildet. Die in vertikaler Richtung verlaufende Länge der Schubeinheit 20 ist jedoch geringer gewählt als die Länge der Aufnahme 13. Damit kann die Schubeinheit 20 linear in dem Gehäuse 10 verschoben werden. An der Schubeinheit 20 sind Koppelelemente 22 festgemacht. Die Koppelelemente 22 sind als Gewindebuchsen ausgebildet, die vorderseitig über die Schubeinheit 20 vorstehen. Die Schubeinheit 20 ist mittig mit einer Ausbrechung 21 versehen. Diese Ausbrechung 21 wird an einer Seite von einem Stellglied 23 begrenzt. Das Stellglied 23 ist als Zahnstange einstückig an die Schubeinheit 20 angeformt. Bei eingesetzter Schubeinheit 20 kämmt die Zahnung des Stellgliedes 23 mit der Zahnung des Betätigungsgliedes 40. Zur Fixierung der Schubeinheit 20, des Rotationskörpers 30 und des Betätigungsgliedes 40 ist eine Halterung 50 verwendet. Die Halterung 50 besitzt eine Grundplatte 51 von der krallenartig vier Rastansätze 53 in Richtung auf das Gehäuse 10 hin abgebogen sind. Mit den Rastaπsätzen 53 kann die Halterung 50 an Rastaufπahmen 1 2 des Gehäuses 10 verrastet werden. Damit bildet das Gehäuse 10, die Schubeinheit 20, der Rotationskörper 30, das Betätigungsglied 40 und die Halterung 50 eine Baueinheit, die vormontiert ist. Die Halterung 50 ist mit einer Lagerhülse 54 versehen. Diese Lagerhülse nimmt den Steckansatz 32 des Rotationskörpers 30 endseitig auf. Mit der Lagerhülse 54 und der Lagerung 1 1 wird eine beidseitige Lagerung des Rotationskörpers 30 erreicht.A thrust unit 20 can be inserted into the receptacle 1 3 of the housing 10. The push unit 20 is plate-shaped. With regard to its width, it is adapted to the width of the receptacle 13. The length of the pusher unit 20 running in the vertical direction is, however, chosen to be less than the length of the receptacle 13. The pusher unit 20 can thus be displaced linearly in the housing 10. Coupling elements 22 are attached to the thrust unit 20. The coupling elements 22 are designed as threaded bushings which protrude from the front over the thrust unit 20. The thrust unit 20 is provided with a cutout 21 in the center. This breakout 21 is limited on one side by an actuator 23. The actuator 23 is integrally formed as a rack on the thrust unit 20. When the pusher unit 20 is inserted, the teeth of the actuator 23 mesh with the teeth of the actuator 40. A bracket 50 is used to fix the pusher unit 20, the rotating body 30 and the actuator 40. The holder 50 has a base plate 51 from which four claw-like projections 53 are bent in the direction of the housing 10. With the Rastaπsätze 53, the bracket 50 can be locked on Rastaufπahmen 1 2 of the housing 10. The housing 10, the thrust unit 20, the rotary body 30, the actuating member 40 and the holder 50 thus form a structural unit which is preassembled. The holder 50 is provided with a bearing sleeve 54. This bearing sleeve takes the plug approach 32 of the rotary body 30 on the end. With the bearing sleeve 54 and the bearing 1 1, a double-sided mounting of the rotary body 30 is achieved.
Zur Befestigung des Gehäuses 10 an der Schranktüre ist das Türblatt 61 mit Bohrungen 64 versehen. Die Bohrungen 64 fluchten mit Gewindeaufnahmen 14 des Gehäuses 10. Die Bohrung 64 ist als Senklochbohrung ausgebildet, so daß eine entsprechende Schraube 66 bündig zur Oberfläche des Türblattes 61 aufgenommen werden kann. Die Schubstange 63 ist mit einer entsprechenden Durchbrechung versehen, so daß die Schraube 66 in die Bohrung 64 eingeführt und in das Gewinde 14 eingeschraubt werden kann. Dadurch, daß die Schraube 66 versenkt gegenüber der Oberfläche des Türblattes 61 aufgenommen ist, kann die Schubstange 63 ungehindert auf dem Türblatt 61 verschoben werden. Zur Ankopplung der Schubstange 63 an die Schubeinheit 20 sind Bohrungen 65 in die Schubstange 63 eingearbeitet. Diese Bohrungen fluchten mit den Koppelelementen 22, die mit entsprechenden Gewinden ausgebildet sind. Über die Bohrungen 65 kann die Schubeinheit 20 mittels Schrauben 67 mit der Schubstange 63 verschraubt werden.To attach the housing 10 to the cabinet door, the door leaf 61 is provided with holes 64. The holes 64 are aligned with threaded receptacles 14 of the housing 10. The hole 64 is designed as a countersunk hole so that a corresponding screw 66 can be received flush with the surface of the door leaf 61. The push rod 63 is provided with a corresponding opening so that the screw 66 can be inserted into the bore 64 and screwed into the thread 14. Characterized in that the screw 66 is sunk in relation to the surface of the door leaf 61, the push rod 63 can be moved freely on the door leaf 61. To couple the push rod 63 to the push unit 20, holes 65 are machined in the push rod 63. These holes are aligned with the coupling elements 22, which are formed with corresponding threads. The thrust unit 20 can be screwed to the push rod 63 via the holes 65 by means of screws 67.
Der Rotationskörper 30 ist von der Vorderseite des Gehäuses 10 her zugänglich. Er dient zur Aufnahme eines Schlüssels oder eines Griffes. Infolge einer Verdrehung dieses Schlüssels oder des Griffes wird der Rotationskörper 30 gedreht. Mit dem Rotationskörper 30 dreht sich auch das Betätigungsglied 40. Das Betätigungsglied 40 verschiebt die Schubstange 20 infolge des Eingriffes in das Stellglied 23. Dadurch, daß die Schubeinheit 20 über die Koppel- eiemente 22 an die Schubstange 63 angeschlossen ist, wird über die Verstellung des Steilgliedes 23 auch eine Verschiebung der Schubstange 63 in vertikaler Richtung bewirkt. In den Fig. 2A bis 2D sind unterschiedliche Montagepositionen dargestellt, in denen das Betätigungsglied 40 dem Stellglied 23 zugeordnet ist. In diesen Zeichnungen ist schematisch eine Innenansicht auf die Schranktür 60 dargestellt, wobei der Schubstangenverschluß stark vergrößert gezeigt ist. Rechts an der Schranktüre sind Scharniere 68 angeordnet, mit denen eine Anscharnierung an einen Schaltschrank-Korpus oder dergleichen erfolgen kann.The rotary body 30 is accessible from the front of the housing 10. It is used to hold a key or a handle. As a result of a rotation of this key or of the handle, the rotating body 30 is rotated. The actuator 40 also rotates with the rotating body 30. The actuator 40 displaces the push rod 20 as a result of the engagement in the actuator 23 Steep member 23 also causes a displacement of the push rod 63 in the vertical direction. 2A to 2D different mounting positions are shown in which the actuator 40 is assigned to the actuator 23. In these drawings, an interior view of the cabinet door 60 is shown schematically, the push rod lock being shown greatly enlarged. Hinges 68 are arranged on the right of the cabinet door, with which hinges can be attached to a cabinet body or the like.
In der Fig. 2A befindet sich das Stellglied 23 quer zur Schließrichtung (Schubrichtung der Schubeinheit 20) links von dem Betätigungsglied 40. Der den Vorschub bewirkende Teil des zahnstangenförmigen Stellgliedes ist in Schubrichtung gesehen rechts von dem Betätigungsglied 40 angeordnet. Mit dieser Konstellation wird bei einer Drehung des Rotationskörpers 30 und damit des Betätigungsgliedes 40 entgegen dem Uhrzeigersinn eine Verschiebung der Schubeinheit 20 vertikal nach unten bewirkt. Wenn nun der Drehsinn des Betätigungsgliedes 40 geändert werden soll, dann muß lediglich die Schubeinheit 20 so gedreht werden, daß das Stellglied 23 quer zur Schubrichtung der Schubeinheit 20 gesehen rechts von dem Betätigungsglied 40 angeordnet ist. Diese Montageposition ist in der Fig. 2B dargestellt. Bei einer solchen Konstellation wird bei einer Drehung des Betätigungsgliedes 40 im Uhrzeigersinn die Schließrichtung nach unten beibehalten.2A, the actuator 23 is located transversely to the closing direction (direction of thrust of the thrust unit 20) to the left of the actuator 40. The part of the rack-shaped actuator causing the feed is arranged to the right of the actuator 40 as seen in the direction of thrust. With this constellation, when the rotary body 30 and thus the actuating member 40 rotate counterclockwise, the thrust unit 20 is displaced vertically downward. If the direction of rotation of the actuator 40 is now to be changed, then only the thrust unit 20 must be rotated so that the actuator 23 is arranged transversely to the direction of thrust of the thrust unit 20 to the right of the actuator 40. This mounting position is shown in Fig. 2B. In such a constellation, the closing direction is maintained downward when the actuator 40 is rotated clockwise.
Die Fig. 2C und 2D zeigen Montagepositionen, bei denen die Schließrichtung nach oben gerichtet ist. Hierbei ist der den Vorschub bewirkende Teil des zahnstangenförmigen Stellgliedes in Schubrichtung gesehen links von dem Betätigungsglied 40 angeordnet. Quer zur Schubrichtung gesehen ist das Stellglied 23 ebenfalls links von dem Betätigungsglied 40 montiert. Bei dieser Montage- Position wird bei einer Drehung des Betätigungsgliedes 40 im Uhrzeigersinn die Schließrichtung nach oben bewirkt. Bei der um 180° getauschten Stellung der Schubeinheit 20 kann die Drehrichtung des Betätigungsgliedes umgekehrt werden (siehe Fig. 2D) . 2C and 2D show mounting positions in which the closing direction is directed upwards. Here, the part of the rack-shaped actuator which causes the feed is arranged to the left of the actuating member 40, as seen in the direction of thrust. Seen transversely to the direction of thrust, the actuator 23 is also mounted to the left of the actuator 40. With this assembly Position is effected when the actuator 40 is rotated clockwise the closing direction upwards. With the thrust unit 20 in the position swapped by 180 °, the direction of rotation of the actuator can be reversed (see FIG. 2D).
