Die Erfindung betrifft einen elektrischen Schalter nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an electrical switch according to the preamble of patent claim 1.
Derartige Schalter werden vor allem bei Elektrohandwerkzeugen, die ein Elektrowerkzeug- Gehäuse sowie einen von einer Spannungsquelle versorgten, im Elektrowerkzeug-Gehäuse befindlichen Elektromotor aufweisen, als Netzschalter zum Ein- und/oder Ausschalten des Elektromotors eingesetzt. Bei diesen Elektrowerkzeugen kann es sich um Bohrmaschinen, Schrauber, Winkelschleifer, Sägen, Hobel, Schleifer, Schwingschleifer, Kreissägen o. dgl. handeln. Zur Erzielung eines Dauerbetriebs im eingeschalteten Zustand kann der Schalter in der Art eines sogenannten Lock-ON arretierbar ausgestaltet sein. Andererseits kann es zur Verringerung der Unfallgefahr auch gewünscht sein, daß der Schalter in der Art eines sogenannten Lock-OFF mit einer Einschaltsperre ausgerüstet ist.Such switches are mainly used in electric hand tools, which have a power tool and a housing supplied by a power source located in the power tool housing electric motor, used as a power switch for switching on and / or off the electric motor. These power tools may be drills, screwdrivers, angle grinders, saws, planers, grinders, orbital sanders, circular saws, or the like. To achieve a continuous operation in the on state, the switch can be designed lockable in the manner of a so-called lock-ON. On the other hand, it may also be desired to reduce the risk of accidents that the switch in the manner of a so-called lock-OFF is equipped with a switch-lock.
Aus der DE 24 10 871 Al ist ein elektrischer Schalter mit einem Schalter-Gehäuse bekannt, in dem sich ein zwischen einem Ausschalt- sowie einem Einschalt-Zustand umschaltbares Kontaktsystem befindet. Am Schalter-Gehäuse ist ein Betätigungsorgan bewegbar gelagert, das als manuelle Handhabe zum Umschalten des Kontaktsystems dient. Der Schalter besitzt weiterhin ein in etwa quer zum Betätigungsorgan manuell zwischen einer Ausgangs- und einer Betätigungsstellung bewegbares Riegelelement. Mittels des Riegelelements ist das Betätigungsorgan im Ausschaltzustand des Kontaktsystems in der Art eines Lock-OFF blockierbar und/oder im Einschalt-Zustand in der Art eines Lock-ON festhaltbar. Das Riegelelement ist aufwendig ausgestaltet und nicht für alle Betätigungsorgane von elektrischen Schaltern geeignet. Der Erfindung liegt die Aufgabe zugrunde, eine einfach ausgestaltete Realisierung der Lock- ON- und/oder Lock-OFF-Funktion für einen elektrischen Schalter, vor allem zur Verwendung in Elektrowerkzeugen, anzugeben. Insbesondere soll das Riegelelement in einfacher Art und Weise zur Verwendung bei Betätigungorganen für einen sogenannten „Overhanging Trigger Switch" geeignet sein.From DE 24 10 871 Al an electrical switch with a switch housing is known in which there is a switchable between a switch-off and a switch-on contact system. On the switch housing, an actuating member is movably mounted, which serves as a manual handle for switching the contact system. The switch further has a movable approximately transversely to the actuator manually between an initial and an actuated position locking element. By means of the locking element, the actuating member in the off state of the contact system in the manner of a lock-OFF can be blocked and / or fixed in the power-on state in the manner of a lock-ON. The locking element is elaborately designed and not suitable for all actuators of electrical switches. The invention has for its object to provide a simply designed realization of the lock-ON and / or lock-OFF function for an electrical switch, especially for use in power tools specify. In particular, the locking element should be suitable in a simple manner for use in actuators for a so-called "Overhanging Trigger Switch".
Diese Aufgabe wird bei einem gattungsgemäßen elektrischen Schalter durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved in a generic electrical switch by the characterizing features of claim 1.
Beim erfindungsgemäßen Schalter steht ein Stößel mit dem Betätigungsorgan sowie dem Kontaktsystem zum Umschalten des Kontaktsystems in Wirkverbindung. Im Gegensatz zum bekannten Schalter wirkt hier das Riegelement zum Festhalten und/oder Blockieren des Betätigungsorgans mit dem in Wirkverbindung zum Kontaktsystem stehenden Stößel zusammen. Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.When the switch according to the invention is a plunger with the actuator and the contact system for switching the contact system in operative connection. In contrast to the known switch acts here, the locking element for holding and / or blocking the actuator together with the standing in operative connection to the contact system plunger. Further embodiments of the invention are the subject of the dependent claims.
In bekannter Art kann der Schalter ein Schalter-Gehäuse aufweisen, das unter anderem zur Aufnahme des Kontaktsystems dient. Das Betätigungsorgan kann bewegbar am Schalter- Gehäuse gelagert sein. Der zum Umschalten des Kontaktsystems dienende Stößel ist beweglich ins Schalter-Gehäuse führend gelagert, wozu sich eine mit einer Dichtung versehene Öffnung am Schalter-Gehäuse befindet.In a known manner, the switch may comprise a switch housing which serves inter alia for receiving the contact system. The actuator may be movably mounted on the switch housing. The serving for switching the contact system plunger is movably mounted in the switch housing leading, for which there is a provided with a seal opening on the switch housing.
Bei einer bevorzugten Ausgestaltung handelt es sich beim elektrischen Schalter um einen sogenannten Overhanging Trigger Switch. Bei diesem Schalter ist das Betätigungsorgan um ein Drehlager verschwenkbar am Schalter-Gehäuse angeordnet. Der Stößel ist am Betätigungsorgan mittels eines in einen Durchbruch am Betätigungsorgan eingreifenden Zapfens angelenkt. Der Durchbruch für den Zapfen besitzt einen Abstand zum Drehlager in der Art eines Exzenters, derart daß die Verschwenkbewegung des Betätigungsorgans im wesentlichen in eine lineare Schiebebewegung des Stößels umgewandelt wird.In a preferred embodiment, the electrical switch is a so-called Overhanging Trigger Switch. In this switch, the actuator is pivotally mounted about a pivot bearing on the switch housing. The plunger is hinged to the actuator by means of an engaging in a breakthrough on the actuator pin. The opening for the pin has a distance from the pivot bearing in the manner of an eccentric, such that the pivoting movement of the actuating member is substantially converted into a linear sliding movement of the plunger.
Um eine ergonomisch gute Bedienung für den Benutzer zu gestatten, kann das Riegelelement verschiebbar im Elektrowerkzeug-Gehäuse gelagert sein. Es bietet sich dann aus Gründen der Vielseitigkeit an, das Riegelelement für den Lock-OFF und den Lock-ON auswechselbar im Elektrowerkzeug-Gehäuse anzuordnen. Zweckmäßigerweise ist das Riegelelement mittels einer elastischen Kraft, die beispielsweise durch eine Feder erzeugt werden kann, aus der Betätigungsstellung in die Ausgangsstellung rückstellbar.In order to allow an ergonomically good operation for the user, the locking element can be slidably mounted in the power tool housing. It is then available for reasons of versatility, to arrange the locking element for the Lock-OFF and the Lock-ON interchangeable in the power tool housing. Appropriately, the locking element by means of an elastic force which can be generated for example by a spring, from the operating position in the initial position recoverable.
In einer einfachen sowie kostengünstigen Ausgestaltung befindet sich ein Ansatz in der Art einer Verlängerung dem Schalter-Gehäuse abgewandt am Stößel, so daß der Zapfen im wesentlichen am Übergang zwischen dem Stößel und dem Ansatz angeordnet ist. Zweckmäßigerweise wirkt eine Rippe am Ansatz mit einer dazu korrespondierenden Aufnahme am Riegelelement für den Lock-ON zusammen. Um eine variable Bedienung des Lock-ON zu gestatten, bietet es sich weiter an, die Aufnahme zweiseitig benachbart zu einem Durchlaß im Riegelelement, der für das Durchgreifen des Ansatzes bei Bewegung des Betätigungsorgans dient, anzuordnen. Mittels einer solchen Ausbildung ist dann vorteilhafterweise die Bewegung des Riegelements sowohl nach links als auch nach rechts für den Lock-ON ermöglicht.In a simple and inexpensive embodiment, an approach in the manner of an extension of the switch housing facing away from the plunger, so that the pin is arranged substantially at the transition between the plunger and the approach. Conveniently, a rib on the neck cooperates with a corresponding receptacle on the locking element for the lock-ON. In order to allow a variable operation of the Lock-ON, it is also advisable to arrange the recording on two sides adjacent to a passage in the locking element, which serves for the passage of the approach upon movement of the actuating member. By means of such training is then advantageously the movement of the locking element allows both to the left and to the right for the lock-ON.
Eine ebenfalls einfache sowie kostengünstige Ausgestaltung des Lock-OFF besteht darin, daß eine Sperrfläche am Ansatz mit einer dazu korrespondierenden Gegenfläche am Riegelelement für den Lock-OFF zusammenwirkt. Zweckmäßigerweise befindet sich ein Durchlaß am Riegelement für die Freigabe des Ansatzes. Um eine variable Bedienung des Lock-OFF zu gestatten, bietet es sich auch hier weiter an, daß jeweils ein Durchlaß beidseitig zur Gegenfläche angeordnet ist. Vorteilhafterweise ist somit wiederum die Bewegung des Riegelements sowohl nach links als auch nach rechts für den Lock-OFF ermöglicht. Bevorzugterweise befindet sich die Rippe an der der Sperrfläche gegenüberliegenden Seite des Ansatzes.A likewise simple and cost-effective embodiment of the lock-OFF is that a locking surface on the approach cooperates with a corresponding mating surface on the locking element for the lock-OFF. Appropriately, there is a passage on the bolt element for the release of the approach. In order to allow a variable operation of the lock-off, it also makes sense here that each one passage is arranged on both sides of the counter surface. Advantageously, in turn, the movement of the locking element is thus possible both to the left and to the right for the lock-OFF. Preferably, the rib is located on the opposite side of the locking surface of the approach.
In einer einfach herzustellenden Ausgestaltung ist der Ansatz in etwa T-förmig ausgebildet. Zweckmäßigerweise ist dann die Sperrfläche an der Oberseite des Querbalkens des Ts befindlich. Die Rippe hingegen befindet sich an der Unterseite des Querbalkens des T's, und zwar indem die Rippe den vertikalen Balken des T's bildet. Zusammenfassend läßt sich für eine besonders bevorzugte Ausgestaltung des Riegelelements das Folgende sagen. Das Einschalten des Schalters wird mit einem Schieber blockiert (Lock-OFF). Durch Betätigung des Schiebers wird das Einschalten freigegeben. Beim Auschalten bewegt sich der Schieber durch Federkraft wieder in seine Sperrtage. Die Ein-Position des Schalters kann durch Betätigung des Schiebers und mittels einer Sperrkontur gehalten werden (Lock-ON). Durch Betätigung des Schalters bewegt sich der Schieber durch Federkraft wieder in die Ausgangspostion und die Sperre wird gelöst. Dann kann der Schalter in die Aus-Position bewegt werden.In an easily manufactured embodiment, the approach is approximately T-shaped. Appropriately, then the blocking surface is located at the top of the crossbar of Ts. The rib, on the other hand, is at the bottom of the crossbeam of the T, in that the rib forms the vertical bar of the T's. In summary, the following can be said for a particularly preferred embodiment of the locking element. Switching on the switch is blocked with a slider (Lock-OFF). Actuation of the slide enables the switching on. When switching off the slider moves by spring force back to its blocking days. The on position of the switch can be held by operating the slider and by means of a locking contour (Lock-ON). By actuating the switch, the slider moves by spring force back into the Ausgangspostion and the lock is released. Then the switch can be moved to the off position.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das Riegelelement einfach und ergonomisch für den Benutzer zu bedienen ist. Außerdem ist das Riegelelement leichtgängig, so daß ein Verhaken und/oder Verklemmen desselben ausgeschlossen ist. Insbesondere bei der Rückstellung des Betätigungsorgans bedeutet ein derartiges Verklemmen und/oder Verhaken eine erhebliche Unfallgefahr für den Benutzer des Elektrowerkzeugs. Handelt es sich um eine Einschaltsperre (Lock-OFF), so ist in einem derartigen Fall das Elektrowerkzeug ungesichert einschaltbar. Bei einer Arretierung (Lock- ON) hingegen ist dann das Elektrowerkzeug nicht mehr abschaltbar. Es ist unmittelbar ersichtlich, daß mit Hilfe der Erfindung die Betriebssicherheit des Elektrowerkzeugs wesentlich gesteigert wird.The advantages achieved by the invention are in particular that the locking element is easy and ergonomic for the user to use. In addition, the locking element is smooth, so that a snagging and / or jamming of the same is excluded. In particular, in the provision of the actuator means such jamming and / or hooking a significant risk of accidents for the user of the power tool. If it is a lock-off, then in such a case, the power tool is switched on unsecured. With a lock (Lock-ON), however, then the power tool can not be switched off. It is immediately apparent that with the help of the invention, the reliability of the power tool is significantly increased.
Weiter ist derselbe Schalter sowohl für die Verwendung mit Arretierung als auch mit Einschaltsperre geeignet. Durch einfachen Wechsel des Schiebers kann von der Funktion Lock-ON auf die Funktion Lock-OFF umgestellt werden, wobei jedoch der Schalter an sich sowie auch die Griffschalen des Elektrowerkzeugs dieselben bleiben. Damit wird die Lagerhaltung für den Schalter erheblich vereinfacht und der elektrische Schalter kann auch noch nachträglich wunschgemäß umgerüstet werden. Insgesamt werden so die Kosten für den elektrischen Schalter verringert.Furthermore, the same switch is suitable both for use with locking and with lock-on. By simply changing the slider, the Lock-ON function can be switched to the Lock-OFF function, but the switch itself as well as the handles of the power tool remain the same. Thus, the storage of the switch is considerably simplified and the electrical switch can also be retrofitted as desired later. Overall, this reduces the cost of the electrical switch.

Das Riegelelement 8 wirkt zum Festhalten bzw. Blockieren des Kontaktsystems mit dem Stößel 7 zusammen. Das Riegelelement 8 ist auswechselbar für den Lock-OFF und/oder den Lock-ON im Elektrowerkzeug-Gehäuse 2 angeordnet. Weiter ist das Riegelelement 8 mittels einer elastischen Kraft, die durch eine Feder 13 erzeugt wird, aus der Betätigungsstellung in die Ausgangsstellung rückstellbar.As further apparent from Fig. 3, a displaceably mounted locking element 8 is arranged in the power tool housing 2 of the power tool 1, which is approximately transversely to the actuating member 5 manually between an initial and an actuating position is movable. The locking element 8 is used so that the actuator 5 in the off state in the manner of a lock-off and / or in the power-on state in the manner of a lock-on for the contact system 20 can be blocked or retained. The locking element 8 cooperates with the plunger 7 for holding or blocking the contact system. The locking element 8 is arranged interchangeable for the lock-OFF and / or the lock-ON in the power tool housing 2. Next, the locking element 8 by means of an elastic force which is generated by a spring 13, from the operating position in the starting position recoverable.
Das Betätigungsorgan 5 ist bewegbar am Schalter-Gehäuse 6 gelagert. Hierfür ist das Betätigungsorgan 5 um ein Drehlager 12 verschwenkbar am Schalter-Gehäuse 6 angeordnet. Der zum Umschalten des Kontaktsystems 20 dienende Stößel 7 ist an einer mit einer Dichtung versehenen Öffnung 9 beweglich ins Schalter-Gehäuse 6 führend gelagert. Weiter ist der Stößel 7 am Betätigungsorgan 5 mittels eines in einen Durchbruch 10 am Betätigungsorgan 5 eingreifenden Zapfens 11 angelenkt. Wie man sieht, ist der Durchbruch 10 für den Zapfen 11 beabstandet zum Drehlager 12 in der Art eines Exzenters, derart daß die Verschwenkbewegung des Betätigungsorgans 5 in wesentlichen in eine lineare Schiebebewegung des Stößels 7 umgewandelt wird.The actuator 5 is movably mounted on the switch housing 6. For this purpose, the actuating member 5 is pivotally mounted about a pivot bearing 12 on the switch housing 6. The serving for switching the contact system 20 ram 7 is movably mounted on a provided with a seal opening 9 leading into the switch housing 6. Next, the plunger 7 is articulated on the actuating member 5 by means of a pin 10 engaging in an opening 10 on the actuating member 5. As you can see, the opening 10 for the pin 11 is spaced from the pivot bearing 12 in the manner of an eccentric, so that the pivoting movement of the actuator 5 is substantially converted into a linear sliding movement of the plunger 7.
Am Stößel 7 befindet sich ein Ansatz 14 in der Art einer Verlängerung, die dem Schalter- Gehäuse 6 abgewandt ist. Der Zapfen 11 ist im wesentlichen in der Nähe des Übergangs zwischen dem Stößel 7 und dem Ansatz 14 angeordnet. Eine Rippe 15 am Ansatz 14 wirkt mit einer dazu korrespondierende Aufnahme 16 am Riegel element 8 für den Lock-ON zusammen. Die Aufnahme 16, 16' ist zweiseitig benachbart zu einem Durchlaß 17 im Riegelelement 8 angeordnet, wobei der Durchlaß 17 für das Durchgreifen des Ansatzes 14 bei Bewegung des Betätigungsorgans 5 dient. Damit ist die Bewegung des Riegelelements 8 für den Lock-ON sowohl nach links und/oder nach rechts ermöglicht. Dieser Bewegungsablauf für den Lock-ON ist schematisch in Fig. 4 näher gezeigt.At the plunger 7 is a projection 14 in the manner of an extension, which faces away from the switch housing 6. The pin 11 is disposed substantially in the vicinity of the transition between the plunger 7 and the projection 14. A rib 15 at the base 14 cooperates with a corresponding receptacle 16 on the bolt element 8 for the lock-ON together. The receptacle 16, 16 'is arranged on two sides adjacent to a passage 17 in the locking element 8, wherein the passage 17 is used for the passage of the projection 14 during movement of the actuating member 5. Thus, the movement of the locking element 8 for the lock-ON is possible both to the left and / or to the right. This sequence of movements for the Lock-ON is shown schematically in Fig. 4 in more detail.
Für den Lock-OFF, der gemäß einem weiteren Ausführungsbeispiel in Fig. 5 zu sehen ist, wirkt eine Sperrfläche 18 am Ansatz 14 mit einer dazu korrespondierenden Gegenfläche 19 am Riegelelement 8 zusammen. Am Riegelement 8 befindet sich ein Durchlaß 17', 17" für die Freigabe des Ansatzes 14. Bevorzugterweise ist je ein Durchlaß 17', 17" beidseitig zur Gegenfläche 19 angeordnet, so daß wiederum die Bewegung des Riegelelements 8 nach links und/oder rechts ermöglicht ist. Der Bewegungsablauf für den Lock-OFF ist schematisch in Fig. 6 näher zu sehen.For Lock-OFF, which can be seen according to a further embodiment in Fig. 5, a blocking surface 18 on the lug 14 cooperates with a corresponding mating surface 19 on the locking element 8. On the bolt element 8 is a passage 17 ', 17 "for Preferably, a passage 17 ', 17 "is preferably arranged on both sides of the mating surface 19, so that in turn the movement of the locking element 8 to the left and / or right is made possible .. The sequence of movements for the lock-OFF is shown schematically in FIG 6 to see more detail.
Wie durch Vergleich von Fig. 4 und Fig. 6 zu erkennen ist, befindet sich die Rippe 15 an der der Sperrfläche 18 gegenüberliegenden Seite des Ansatzes 14. Der Ansatz 14 ist in etwa T- förmig ausgestaltet. Dabei ist die Sperrfläche 18 an der Oberseite des Querbalkens des T's befindlich. Desweiteren ist die Rippe 15 an der Unterseite des Querbalkens des T's befindlich, und zwar bildet die Rippe 15 den vertikalen Balken des T's. Somit kann, falls gewünscht, der Lock-ON sowie der Lock-OFF auch kombiniert für den Schalter 4 im Elektrowerkzeug 1 angeordnet sein.As can be seen by comparing FIGS. 4 and 6, the rib 15 is located on the opposite side of the locking surface 18 of the projection 14. The projection 14 is configured in an approximately T-shaped. In this case, the blocking surface 18 is located at the top of the crossbar of the T's. Furthermore, the rib 15 is located at the bottom of the crossbar of the T's, namely the rib 15 forms the vertical bar of the T's. Thus, if desired, the lock-ON and the lock-OFF can also be arranged in combination for the switch 4 in the power tool 1.
