Description

Die Erfindung richtet sich auf einen Türaußengriff der im Oberbegriff des Anspruches 1 angegebenen Art. Zwecks eines höheren Bedienungskomforts sind am Türaußengriff Entriegelungssensoren und Verriegelungssensoren zum Verriegeln und Entriegeln eines Schlosses vorgesehen.The invention is directed to an outside door handle specified in the preamble of claim 1 Art. For the purpose of a higher ease of operation unlocking sensors and locking sensors for locking and unlocking a lock are provided on the outside door handle.

Einen Türaußengriff dieser Art ist in der US 2001/0004233 A1 gezeigt. Dort werden zwei auf die Bewegung der Handhabe ansprechende Sensoren verwendet, die aus zwei berührungslos über ein Magnetfeld miteinander kommunizierenden Sensorteilen bestehen. Ein zusammengehöriges Paar von Sensorteilen besteht aus einem Permanentmagneten einerseits und einem Reedkontakt andererseits. Sowohl alle Reedkontakte als auch einige zu ihrer Steuerung und Signalauswertung dienende elektronische Bauteile sind in der schwenkbeweglichen Handhabe integriert. Von einem Steuergerät im Fahrzeug kommende elektrische Leitungen sind durch eine Öffnung im Träger hindurch bis zur Handhabe geführt und verlaufen in der Handhabe bis zu den Reedkontakten und elektronischen Bauteilen. Damit die elektrischen Leitungen die Schwenkbewegung der Handhabe nicht beeinträchtigen, verlaufen sie im Bereich des Schwenklagers zwischen der Handhabe und dem Träger.An outside door handle of this kind is in the US 2001/0004233 A1 shown. There, two responsive to the movement of the handle sensors are used, which consist of two non-contact via a magnetic field communicating sensor parts. An associated pair of sensor parts consists of a permanent magnet on the one hand and a reed contact on the other hand. Both all reed contacts as well as some electronic components used for their control and signal evaluation are integrated in the pivoting handle. From a control unit in the vehicle coming electrical lines are passed through an opening in the carrier through to the handle and extend in the handle up to the reed contacts and electronic components. So that the electrical lines do not affect the pivoting movement of the handle, they run in the region of the pivot bearing between the handle and the carrier.

Bei Türaußengriffen ist es üblich, den Träger auf der Innenseite der Türaußenhaut zu befestigen und die Handhabe dann nachträglich, von der Außenseite der Tür aus, durch Durchbrüche in der Türaußenverkleidung hindurch im Träger zu montieren. Bei dieser Montage entsteht das Drehlager zwischen der Handhabe und dem Träger. Wie die DE 100 62 042 A1 und die DE 196 33 894 A1 zeigen, sind in diesem Fall elektrische Kupplungsteile in der Leitung erforderlich, die bei der Montage und Demontage der Handhabe miteinander gekuppelt bzw. entkuppelt werden müssen. Das ist platzaufwendig, störanfällig, umständlich erfordert beim Kuppeln und Entkuppeln viel Zeit und Aufmerksamkeit.For outside door handles, it is customary to attach the carrier on the inside of the door outer skin and then subsequently to mount the handle, from the outside of the door, through openings in the door outer panel in the carrier. During this assembly, the pivot bearing between the handle and the carrier is created. As the DE 100 62 042 A1 and the DE 196 33 894 A1 show, in this case, electrical coupling parts in the line are required, which must be coupled or uncoupled during assembly and disassembly of the handle. This is space consuming, prone to failure, cumbersome requires when coupling and uncoupling much time and attention.

Diese Nachteile ergeben sich auch aus dem ersten und dritten Ausführungsbeispiel der US 6,459,373 B1 , wo stets elektrische Leitungen an der schwenkbeweglichen Handhabe erforderlich sind, die zu zwei dort angeordneten Reedkontakten führten. Ein Permanentmagnet, der das Magnetfeld erzeugt, ist beim ersten. Ausführungsbeispiel ebenfalls in der Handhabe integriert, während abschirmende Flügel in einem daneben angeordneten Körper angeordnet sind, der im Bereich des üblichen Schließzylinders positioniert ist. Im dirtten Ausführungsbeispiel sind im Bereich des Schließzylinders zwei Reedkontakte angeordnet, weshalb im Bereich des Schließzylinders elektrische Leitungen verlegt werden müssen, die seinen Ein- und Ausbau erschweren. Eine eigenständige, lösbare Gehäuseeinheit mit dort befindlichen Sensorelementen fehlt. Deshalb ist daraus auch nicht entnehmbar, eine Gehäuseeinheit wahlweise am Träger anzubringen oder davon zu lösen.These disadvantages are also apparent from the first and third embodiment of the US Pat. No. 6,459,373 B1 where electrical lines are always required on the pivoting handle, which led to two reed contacts arranged there. A permanent magnet that generates the magnetic field is at the first. Embodiment also integrated in the handle, while shielding wings are arranged in a body arranged next to it, which is positioned in the region of the conventional lock cylinder. In the third embodiment, two reed contacts are arranged in the region of the lock cylinder, for which reason electrical lines must be laid in the area of the lock cylinder, which makes its installation and removal more difficult. An independent, detachable housing unit with sensor elements located there is missing. Therefore, it can not be deduced from this, either to attach a housing unit on the carrier or to solve it.

Aus der DE 101 53 143 C1 ist es bekannt, bei einem Griff mit einer klappbeweglichen Handhabe eine lösbare Gehäuseeinheit vorzusehen, in welche die kompletten Sensoren angeordnet sind. Alle Sensoren für die Verriegelung befinden sich in einem Hauptgehäuse. Ein davon unabhängiger Sensor für die Entriegelung befindet sich am Stirnende eines abragenden Fingers. Die dortige klappbewegliche Handhabe besitzt keinen Ausleger, der am freien Ende der schwenkbaren Handhabe sitzt und auf ein Schloss wirkt.From the DE 101 53 143 C1 It is known to provide for a handle with a hinged handle a detachable housing unit, in which the complete sensors are arranged. All sensors for the lock are located in a main housing. An independent sensor for unlocking is located at the front end of a protruding finger. The local folding movable handle has no arm, which sits at the free end of the pivoting handle and acts on a lock.

Die US 6,218,933 B1 zeigt einen zweiteilige Sensor, der nur im Träger angeordnet ist. Der eine Teil des Sensors besteht aus einem Infrarotsender und der andere Teil aus einem Infrarotempfänger im Träger, die mit einem Reflektor an der gegenüberliegenden Innenfläche der Handhabe ausgerichtet sind. Wenn ein Objekt in den freien Raum zwischen den ruhenden Sensor und den Handgriff gelangt, wird der Strahlengang zwischen den beiden Sensorteilen unterbrochen, was zur Entriegelung eines Schlosses durch eine Elektronik genutzt wird. Ein Sensor zur Überwachung der Bewegung der Handhabe ist nicht vorgesehen.The US 6,218,933 B1 shows a two-part sensor, which is arranged only in the carrier. One part of the sensor consists of an infrared transmitter and the other part of an infrared receiver in the carrier, which are aligned with a reflector on the opposite inner surface of the handle. When an object enters the free space between the resting sensor and the Hand grip, the beam path between the two sensor parts is interrupted, which is used for unlocking a lock by an electronic system. A sensor for monitoring the movement of the handle is not provided.

Die FR 2 820 448 A1 verwendet zur Entriegelung des Schlosses einen elektrischen Druckschalter, dessen Betätigungsglied von der verschwenkten Handhabe mechanisch aus einer Einschaltstellung in eine Ausschaltstellung umgesteuert wird. Zur Umsteuerung des Betätigungsglieds besitzt die Handhabe eine Aussparung. Eine berührungslose Kommunikation über ein Magnetfeld erfolgt hier nicht. Über ein Magnetfeld miteinander kommunizierende Sensorteile, die berührungslos aufeinander wirken, sind nicht vorgesehen.The FR 2 820 448 A1 used to unlock the lock, an electrical pressure switch whose actuator is reversed by the pivoted handle mechanically from a closed position into an open position. For reversing the actuator, the handle has a recess. Non-contact communication via a magnetic field does not take place here. About a magnetic field communicating with each other sensor parts that interact with each other without contact, are not provided.

Aus der DE 101 53 142 C1 ist ein Türaußengriff anderer Art bekannt, wo zwei kapazitive Sensoren zum Verriegeln und Entriegeln des Schlosses komplett in einem Gehäuse angeordnet sind, das bedarfsweise an der Vorderseite des Trägers angeordnet wird. Die kapazitiven Elektroden im montierten Gehäuse wirken mit der menschlichen Hand zusammen, wenn sich diese der Handhabe nähert. Wegen des großen Abstandes zwischen der Hand an der Handhabe und der Elektrode im Gehäuse muss dieser kapazitive Sensor sehr empfindlich gebaut werden. Weil dieser bekannte Türgriff bereits auf geringe Kapazitiätsänderungen anspricht, ist er störanfällig gegenüber Umwelteinflüssen, wie Schnee oder Regen, der auf die Handhabe trifft. Dies führt zu Entriegelungen und Versiegelungen des Schlosses, die unerwünscht sind und böse Folgen haben können.From the DE 101 53 142 C1 For example, an outside door handle of another type is known, where two capacitive sensors for locking and unlocking the lock are completely arranged in a housing, which is arranged on the front of the carrier as required. The capacitive electrodes in the assembled housing interact with the human hand as it approaches the handle. Because of the large distance between the hand on the handle and the electrode in the housing, this capacitive sensor must be made very sensitive. Because this well-known door handle already responds to small changes in capacity, it is susceptible to environmental influences, such as snow or rain, which hits the handle. This leads to unlocking and sealing of the lock, which are undesirable and can have nasty consequences.

Der Erfindung liegt die Aufgabe zugrunde, den im Oberbegriff des Anspruches 1 genannten Türaußengriff zu vereinfachen und zu verbessern. Dies wird erfindungsgemäß durch die im Anspruch 1 genannten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The invention has for its object to simplify the above-mentioned in the preamble of claim 1 outside door handle and improve. This is inventively achieved by the measures mentioned in claim 1, which has the following special significance.

Es wird eine besondere Gehäuseeinheit verwendet, die aus einem Hauptgehäuse und aus einem davon abragenden Gehäusefinger besteht. Das Hauptgehäuse dient zur Befestigung der ganzen Gehäuseeinheit am Träger und nimmt die zugehörigen elektronischen Bauteile für den Sensor auf. Die beiden Sensorteile sind von einander getrennt angeordnet und zwar der Permanentmagnet nur in dem Ausleger der Handhabe, die frei von jeglichen elektronischen Bauteilen oder elektrischen Leitungen ist. Der andere Sensorteil, nämlich das Hallelement oder der Reedkontakt, ist dagegen nur im Gehäusefinger der Gehäuseeinheit integriert und kommt neben den Ausleger, deshalb gehen die elektrischen Leitungen nur vom Hauptgehäuse dieser Gehäuseeinheit aus, was in den Ein- und Ausbau weder der Handhabe noch des Schließzylinders beeinträchtigt. Die Handhabe beinhaltet also keine elektronischen Bauteile und keine elektrischen Kontakte. Um eine universelle Verwendbarkeit des erfindungsgemäßen Türaußengriffs zu gewährleisten, ist in dem Ausleger der Handhabe lediglich der preiswerte Permanentmagnet integriert, der ein magnetisches Feld erzeugt.A special housing unit is used, which consists of a main housing and a housing finger protruding therefrom. The main body serves to attach the entire housing unit to the carrier and receives the associated electronic components for the sensor. The two sensor parts are arranged separately from each other and that is the permanent magnet only in the arm of the handle, which is free of any electronic components or electrical wiring. The other sensor part, namely the Hall element or the reed contact, however, is integrated only in the housing finger of the housing unit and comes next to the boom, so go the electrical lines only from the main body of this housing unit, resulting in the installation and removal of neither the handle nor the lock cylinder impaired. The handle thus contains no electronic components and no electrical contacts. In order to ensure a universal usability of the outside door handle according to the invention, only the inexpensive permanent magnet is integrated in the arm of the handle, which generates a magnetic field.

Eine erste Verwendungsmöglichkeit der Erfindung besteht darin, dass der Türaußengriff mit seiner vorerwähnten Handhabe nur auf mechanische Weise zusammenwirkt. Es liegt dann eine "Standardausführung" des Türaußengriffs vor, wo weder ein Sensor noch elektronische Bauteile benötigt werden.A first use of the invention is that the outside door handle cooperates with his aforementioned handle only in a mechanical manner. There is then a "standard version" of the outside door handle, where neither a sensor nor electronic components are needed.

Der Türaußengriff mit dieser Handhabe kann aber, in einer zweiten Verwendungsmöglichkeit, zugleich für eine elektrische Umsteuerung des Schlosses genutzt werden, die man als "Komfortausführung" bezeichnen kann. In diesem Fall wird die vorgenannte Gehäuseeinheit an dem Träger des Türaußengriffs befestigt, in dessen Gehäusefinger das Hallelement oder der Reedkontakt mit zugehöriger Sensorelektronik integriert sind. Erst von dieser ruhenden Gehäuseeinheit gehen elektrische Leitungen aus, die über Leitungen zum Steuergerät führen. Das im Gehäuse ortsfeste Hallelement bzw. der dortige Reedkontakt sensieren eine Bewegung der Handhabe durch Veränderung des Magnetfelds aufgrund des im Ausleger integrierten Permanentmagneten. Die Gehäuseeinheit wird am Träger angebracht, wenn es auf die erwähnte "Komfortausbildung" des Türaußengriffs ankommt. Bei einer "Standardausführung" genügt es, diese Gehäuseeinheit vom Träger zu lösen.The outside door handle with this handle can, however, be used in a second possible use, at the same time for an electrical reversal of the castle, which can be described as a "comfort version". In this case, the aforementioned housing unit is fastened to the support of the outside door handle, in the housing finger of which the Hall element or the reed contact with associated sensor electronics are integrated. Only from this dormant housing unit go out electrical lines that lead via lines to the controller. The stationary Hall element in the housing or the local reed contact senses a movement of the handle by changing the magnetic field due to the integrated permanent magnet in the boom. The housing unit is attached to the carrier when referring to the mentioned "comfort training" of the outside door handle arrives. In a "standard version" it is sufficient to solve this housing unit from the carrier.

Weitere Maßnahmen und Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen, der nachfolgenden Beschreibung und der Zeichnung. In der Zeichnung ist
ein Ausführungsbeispiel der Erfindung schematisch dargestellt.Further measures and advantages of the invention will become apparent from the other dependent claims, the following description and the drawings. In the drawing is
an embodiment of the invention shown schematically.

Im Türinneren 11 ist auf der Rückseite 12 einer Türaußenhaut 13 ein Träger 10 befestigt. Auf der Vorderseite 14 der Türaußenhaut 13 befindet sich eine Handhabe 20, die als Ziehgriff-Handhabe ausgebildet ist, welcher mit seinem einen Ende 21 bei 15 am Träger 10 schwenkbar gelagert ist, während am anderen Ende 22 ein Ausleger. 23 sitzt. Der Ausleger 23 ist hakenförmig ausgebildet und wirkt mit einem Arbeitsglied 16 zusammen, das zu einem nicht näher gezeigten Schloss in der Tür führt.In the interior of the door 11, a carrier 10 is attached to the back 12 of a door outer skin 13. On the front side 14 of the door outer skin 13 is a handle 20 which is designed as a pull handle handle, which is pivotally mounted with its one end 21 at 15 on the carrier 10, while at the other end 22 a boom. 23 is sitting. The boom 23 is hook-shaped and cooperates with a working member 16 which leads to a lock not shown in detail in the door.

Das Schloss ist zwischen einer Verriegelungsposition, wo die Handhabe für das Öffnen der Tür unwirksam ist, in eine entriegelte Position überführbar, wo die Handhabe 20 bei Betätigung im Sinne des Pfeils 24 für das Schloss wirksam ist und es öffnet. Die Betätigungslage der Handhabe ist in der Zeichnung strichpunktiert veranschaulicht und mit 20' bezeichnet. Dabei gelangt das Arbeitsglied in seine mit 16' bezeichnete, strichpunktiert angedeutete Arbeitsstellung.The lock is transferable between a locking position where the handle for opening the door is ineffective, in an unlocked position, where the handle 20 when operated in the direction of the arrow 24 for the lock is effective and it opens. The operating position of the handle is illustrated in phantom in the drawing and designated 20 '. In this case, the working member enters his designated 16 ', dash-dotted lines indicated working position.

Neben der Handhabe 20 sitzt an der Vorderseite der Türaußenhaut 13 eine mit dem Außenprofil der Handhabe 20 konforme Abdeckung 25, wo zweckmäßigerweise eine Befestigung mit dem Träger 10 besteht. An dieser Stelle sitzt im vorliegenden Fall auch noch ein Schließzylinder-Turm 17 im Träger, dessen Ausgangsende 18 mit dem Schloss zusammenwirkt. Der Schließzylinder-Turm 17 ist an seinem vorderen Stirnende 19 im Bereich der Abdeckung 25 mittels eines nicht näher gezeigten Schlüssels zugänglich. Dieser Schließzylinder-Turm 17 wird normalerweise nur im Notfall benutzt, wenn die Elektronik im Fahrzeug versagt. Daher kann der Schließzylinder 17 in manchen Anwendungsfällen ganz fehlen oder durch eine Turm-Attrappe ersetzt sein.In addition to the handle 20 sits on the front of the outer door skin 13 with the outer profile of the handle 20 compliant cover 25, where expediently a Attachment with the carrier 10 is. At this point, sitting in the present case, a lock cylinder tower 17 in the carrier whose output end 18 cooperates with the lock. The lock cylinder tower 17 is accessible at its front end 19 in the region of the cover 25 by means of a key not shown in detail. This lock cylinder tower 17 is normally used only in an emergency when the electronics in the vehicle fails. Therefore, the lock cylinder 17 may be completely absent or replaced by a tower dummy in some applications.

Auf der Rückseite 26 vom Träger 10 ist eine besondere Gehäuseeinheit 30 angebracht, die in ein Hauptgehäuse 31 und einen davon abragenden Gehäusefinger 32 gegliedert ist. Am freien Fingerende 33 befindet sich die Wirkfläche 27 eines Näherungs- oder Berührungssensors, dessen elektronische Bauteile, wie bei 28 strichpunktiert angedeutet, im Inneren des Hauptgehäuses 31 integriert sind. Dieser Sensor 27 wirkt im vorliegenden Fall kapazitiv und dient zum Verriegeln des Schlosses, weshalb er nachfolgend kurz "Verriegelungssensor" bezeichnet werden soll. Ein solcher Verriegelungssensor könnte auch aus einem Berührungsschalter oder einem Druckschalter gebildet sein. Wenn sich eine Person mit ihrer Hand der Wirkfläche 27 nähert, spricht der Sensor an. Die Sensorelektronik bewirkt aber nur dann eine Verriegelung des Schlosses, wenn diese Person im Besitz einer Zugangsberechtigung ist, z.B. einer codierten Karte, wie sie bei einem sogenannten "Keyless-Go"-System verwendet wird. Das Fingerende 33 wird möglichst nah an die Abdeckung 25 herangeführt. Dafür besitzen sowohl der Träger 10 als auch die Türaußenhaut 13 in diesem Bereich einen Durchbruch 29. Diesen Durchbruch 29 durchgreift aber auch der Ausleger 23 der Zieh-Handhabe 20.On the back 26 of the carrier 10, a special housing unit 30 is mounted, which is divided into a main housing 31 and a projecting housing finger 32 thereof. At the free end of the finger 33 is the active surface 27 of a proximity or touch sensor whose electronic components, as indicated by dash-dotted lines at 28, are integrated in the interior of the main housing 31. In the present case, this sensor 27 acts capacitively and serves to lock the lock, which is why it should be referred to below as "locking sensor". Such a locking sensor could also be formed from a touch switch or a pressure switch. When a person approaches the active surface 27 with their hand, the sensor responds. However, the sensor electronics only lock the lock if that person is in possession of an access authorization, e.g. a coded card, as used in a so-called "keyless-go" system. The finger end 33 is brought as close as possible to the cover 25. For this, both the carrier 10 and the outer door skin 13 in this area have a breakthrough 29. This breakthrough 29 passes through but also the boom 23 of the pull handle 20th

Der Türaußengriff besitzt aber auch noch einen summativ mit 37 gekennzeichneten Entriegelungssensor, dessen Sensorelektronik 38, wie gestrichelt in der Zeichnung dargestellt, ebenfalls im Hauptgehäuse 31 integriert ist. Der Entriegelungssensor 37 spricht hier auf eine Bewegung 24 der Handhabe an und soll deswegen nachfolgend "Bewegungssensor" genannt werden. Der Bewegungssensor 37 ist zweiteilig ausgebildet und besteht aus einem ruhenden Teil 34, der in den Gehäusefinger 33 integriert ist und nachfolgend kurz "Stationärteil" bezeichnet werden soll. Dem Stationärteil 34 zugeordnet ist ein beweglicher Teil 35, welcher "Bewegungsteil" genannt werden soll. Der Bewegungsteil 35 ist in den Ausleger 23 integriert. Der Gehäusefinger 32 und der Ausleger 23 verlaufen wenigstens bereichsweise parallel nebeneinander und der Stationärteil 34 sowie Bewegungsteil 35 sind in den einander zugekehrten Flächen 39, 36 dieser Bauteile 32, 23 angeordnet.But the outside door handle also has a summation with 37 marked unlocking sensor whose sensor electronics 38, as shown in dashed lines in the drawing, also in the main housing 31 is integrated. The unlocking sensor 37 responds here to a movement 24 of the handle and should therefore be referred to below as "motion sensor". The motion sensor 37 is formed in two parts and consists of a stationary part 34 which is integrated in the housing finger 33 and will be hereinafter referred to as "stationary part". the Stationary part 34 is associated with a movable part 35, which should be called "moving part". The moving part 35 is integrated in the boom 23. The housing finger 32 and the boom 23 extend at least partially parallel to each other and the stationary part 34 and moving part 35 are arranged in the mutually facing surfaces 39, 36 of these components 32, 23.

Im vorliegenden Fall besteht der Stationärteil 34 aus einem Hallelement, während der Bewegungsteil 35 von einem Permanentmagneten gebildet ist. Bei der Bewegung 24 der Handhabe 20 in die Betätigungslage 20' bewegt sich der Permanentmagnet 35 an dem stationären Hallelement 34 vorbei und bewirkt aufgrund des Halleffekts dort ein Signal, welches von der Sensorelektronik 38 ermittelt und über eine elektrische Steckverbindung 40 und ein Kabel 41 einem elektronischen Steuergerät im Fahrzeug zugeführt wird. Von dort aus kommt dann ein Steuerimpuls, welcher das Schloss in dieser Tür und, bei einer Zentralverriegelung im Fahrzeug, auch alle übrigen Türen und Klappen entriegelt.In the present case, the stationary part 34 consists of a Hall element, while the moving part 35 is formed by a permanent magnet. During the movement 24 of the handle 20 into the actuation position 20 ', the permanent magnet 35 moves past the stationary Hall element 34 and due to the Hall effect causes a signal there, which is detected by the sensor electronics 38 and via an electrical connector 40 and a cable 41 an electronic Control unit is supplied in the vehicle. From there comes then a control pulse, which unlocks the lock in this door and, in a central locking in the vehicle, all other doors and flaps.

Es versteht sich, dass der Bewegungssensor auch in anderer Weise ausgebildet sein kann, z.B. in Form von Reed-Kontakten. Eine andere Möglichkeit wäre als Stationärteil 34 einen elektrischen Schalter mit einem beweglichen Schaltglied zu verwenden, dem, als Bewegungsteil 35, z.B. ein ortsfester Schaltnocken am Ausleger 23 zugeordnet ist, welcher bei der Bewegung 24 das Schaltglied betätigt.It is understood that the motion sensor can also be designed in other ways, e.g. in the form of reed contacts. Another possibility would be to use as stationary part 34 an electric switch with a movable switching element, which, as a moving part 35, e.g. a stationary switching cam is assigned to the boom 23, which actuates the switching element during movement 24.

Um gute Gleiteigenschaften im Bereich des Durchbruchs 29 vom Träger 10 zur Führung des Auslegers 23 zu erhalten, empfiehlt es sich, jene Umfangsbereiche des Auslegers, welche mit den in der Zeichnung mit 43 gekennzeichneten Führungsfläche in Berührung kommen, mit einem nicht näher gezeigten Gleitschuh zu umkleidet, der z.B. einen U-Querschnitt aufweist. Dieser Gleitschuh besitzt Gleitflächenteile, die bei der Betätigung 24 der Handhabe 20 an den Führungsflächen 43 im Träger 10 entlang gleiten. Solche Gleitflächenteile können auch die weitere Funktion übernehmen, zur Sicherung des Bewegungsteils 35 vom Bewegungssensor 37 zu dienen.In order to obtain good sliding properties in the region of the opening 29 from the carrier 10 for guiding the jib 23, it is recommended that those peripheral regions of the jib, which come into contact with the guide surface identified in the drawing by 43, be clad with a sliding shoe not shown in detail , which, for example, has a U-shaped cross section. This shoe has sliding surface parts which slide on the guide surfaces 43 in the carrier 10 during actuation 24 of the handle 20. Such Gleitflächenteile can also take over the additional function of serving to secure the moving part 35 of the motion sensor 37.

Dazu ist der Ausleger 23 mit einer hinterschnittenen Quernut 42 versehen. Die Quernut 42 hat im vorliegenden Fall ein Trapezprofil, in welches der Permanentmagnet 35 durch eine der beiden seitlichen Nutöffnungen in den Ausleger 23 eingeschoben wird. Wenn der Gleitschuh auf dem Ausleger 23 sitzt, dann verschließ er die beidendigen Nutöffnungen der Quernut 42. So wird die Position der Permanentmagnet 35 in der Quernut 42 gesichert.For this purpose, the boom 23 is provided with an undercut transverse groove 42. The transverse groove 42 has in the present case a trapezoidal profile, in which the permanent magnet 35 is inserted through one of the two lateral groove openings in the boom 23. If the shoe sits on the boom 23, then it closes the both-end groove openings of the transverse groove 42. Thus, the position of the permanent magnet 35 is secured in the transverse groove 42.
