Der Halter 5 wird von einer kappenförmigen Abdeckung 6 aufgenommen, die an beiden Seiten jeweils mit einem entsprechenden Schraubenloch 7 für eine Senkkopfschraube zum Befestigen an der Klappe, dem Deckels od.dgl. unter Aufnahme des Halters 5 versehen ist.The radius actuator 4 is pivotable on an axis Flap, cover or the like (shown in dashed lines) using screws in the Distance R from the axis of the flap, the cover or the like. attached and has an elongated holder 5 in the plane of the key 3 for the key 3. The holder 5 is covered by a cap-shaped cover 6 added, each on both sides with a corresponding Screw hole 7 for a countersunk screw for fastening to the flap, the lid or the like. is provided with the holder 5.

Der Schlüssel 3 besitzt einen mittleren Schlitz 8 zum Umgreifen einer in dem Schlitz 2 des Sicherheitsschalters 1 befindlichen Zwischenwandung 9 und weist ferner Keilflächen 10 tragende Fortsätze 11 an der dem Halter 5 abgewandten Seite benachbart zum Schlitz 8 auf. The key 3 has a central slot 8 for reaching around an intermediate wall located in the slot 2 of the safety switch 1 9 and furthermore has extensions 11 carrying wedge surfaces 10 the side facing away from the holder 5 adjacent to the slot 8.

Der Halter 5 besitzt an seinen beiden in der Ebene des Schlüssels 3 gegenüberliegenden Enden Wellenstummel 12. Ferner ist eine Bodenplatte 13 für den Halter 5 vorgesehen, die endseitig Lager 14 für die Wellenstummel 12 aufweist (sh. insbesondere Fig. 6), so daß der Halter 5 gegenüber der Bodenplatte 13 drehbar angeordnet ist.The holder 5 has two in the plane of the key 3 opposite ends stub shaft 12. Furthermore, a base plate 13 provided for the holder 5, the end bearing 14 for the Has stub shaft 12 (see in particular Fig. 6), so that the holder 5th is rotatably arranged with respect to the base plate 13.

Die Lager 14 sind im dargestellten Ausführungsbeispiel auf die Wellenstummel 12, diese über mehr als 200° umgreifend, aufschnappbar ausgebildet, sie können aber auch aus miteinander verbindbaren Hälften bestehen, wobei jeweils eine Hälfte einstückig mit der Bodenplatte 13 ausgebildet ist, während die andere Hälfte unabhängig oder in der Abdekkung 6 ausgebildet ist.The bearings 14 are in the illustrated embodiment on the Wave stub 12, which grips over more than 200 °, can be snapped on trained, but they can also be made of interconnectable halves consist, one half each in one piece with the base plate 13 is formed while the other half is independent or in the cover 6 is formed.

Der zwischen den Wellenstummeln 12 befindliche Mittelteil des Halters 5 besitzt eine durchgehende radiale Ausnehmung 15, die an der der Bodenplatte 13 abgewandten Seite in einem axialen Schlitz 16 mündet. Quer zur Ausnehmung 15 ist im Halter 5 eine Bohrung angeordnet, die eine Schwenkachse 17 aufnimmt, um die der Schlüssel 3 in seiner Ebene drehbar ist. Der Schlüssel 3 besitzt hierzu einen mittleren Fortsatz 18, der an der den Fortsätzen 11 gegenüberliegenden Seite angeordnet ist. Die Schwenkachse 17 wird gegen Herausfallen durch die Abdeckung 6 gesichert.The middle part of the shaft stub 12 Holder 5 has a continuous radial recess 15 which on the the side facing away from the base plate 13 opens into an axial slot 16. Transverse to the recess 15, a hole is arranged in the holder 5, the one Includes pivot axis 17 about which the key 3 is rotatable in its plane is. For this purpose, the key 3 has a central extension 18, which the side opposite the extensions 11 is arranged. The The pivot axis 17 is secured against falling out by the cover 6.

An einer Seite der Ausnehmung 15 ist im Bereich des Schlitzes 16 zwischen dessen Grund und der benachbarten Unterkante des Schlüssels 3 eine Druckfeder 19 (Schraubenfeder) eingespannt, um den Schlüssel 3 in eine in seiner Ebene verschwenkte Position vorzuspannen. Die Druckfeder 19 wird zweckmäßigerweise mit einem Ende auf einen Zapfen 20 am Grund des Schlitzes 16 geklemmt.On one side of the recess 15 is in the area of the slot 16 between the bottom and the adjacent lower edge of the key 3 a compression spring 19 (coil spring) clamped to the key 3 in to bias a position pivoted in its plane. The compression spring 19 is expediently with one end on a pin 20 at the bottom of the slot 16 clamped.

Auf der gegenüberliegenden Seite der Ausnehmung 15 ist eine Bohrung 21 für eine Stellschraube 22 (Senkkopfschraube) angeordnet, wobei der Kopf der Stellschraube 22 als Anschlag für die benachbarte Unterkante des Schlüssels 3 dient. Die Stellschraube 22 ist selbsthemmend angebracht.On the opposite side of the recess 15 is one Bore 21 arranged for a set screw 22 (countersunk screw), the head of the set screw 22 as a stop for the adjacent lower edge the key 3 is used. The set screw 22 is self-locking appropriate.

Zweckmäßigerweise ist die Bohrung 21 anfänglich im Schnitt mehreckig, beispielsweise sechseckig, und ohne Gewinde. Die Stellschraube 22 schneidet sich beim späteren Eindrehen selbsthemmend ein.Appropriately, the bore 21 is initially in section polygonal, for example hexagonal, and without thread. The set screw 22 cuts itself self-locking when screwing in later.

Die Stellschraube 22 ist mit einem Innensechskant 23 versehen und derart gegenüber dem Schlitz 16, dessen Breite geringfügig größer als die Stärke des Schlüssels 3 ist, versetzt angeordnet, daß die Stellschraube 22 mittels eines Steckschlüssels verstellbar ist, ohne daß der Schlüssel 3 hierbei stört.The set screw 22 is provided with a hexagon socket 23 and so opposite the slot 16, the width of which is slightly larger as the strength of the key 3 is offset that the set screw 22 is adjustable by means of a socket wrench without the Key 3 interferes with this.

Auf diese Weise läßt sich der Schwenkwinkel des Schlüssels 3 gegenüber dem Halter 5 in der Schwenkebene des Schwenkkreises des Radiusbetätigers 4 (Schlüsselebene) zwischen einer Einführstellung (Fig. 1) und einer Schalterbetätigungsstellung und damit zwischen 0° und einem Maximalwinkel einstellen, wobei durch Drehen des Halters 5 um 180° ein entsprechender Schwenkwinkel in entgegengesetzter Richtung erreicht wird.In this way, the pivot angle of the key 3rd opposite the holder 5 in the swivel plane of the swivel circle of the radius actuator 4 (key level) between an insertion position (Fig. 1) and a switch actuation position and thus between 0 ° and one Set the maximum angle, turning the holder 5 by 180 ° corresponding swivel angle reached in the opposite direction becomes.

Zwischen der Bodenplatte 13 und dem mittleren Bereich des Halters 5 ist eine Druckfeder 24 (Schraubenfeder) eingespannt, die sich im dargestellten Ausführungsbeispiel in eine seitliche, bodenseitige, mit einem Zapfen 25 versehene Ausnehmung 26 des Halters 5 erstreckt und diesen in eine gegenüber dem Boden gekippte Position vorspannt (Fig. 5), in der der Schlüssel 3 aus seiner Ebene und damit senkrecht aus der Ebene des Schwenkkreises des Radiusbetätigers 4 heraus verschwenkt oder gekippt ist (vgl. auch Fig. 2). Um ein Verschwenken bei geringer Bauhöhe zu erzielen, ist der Halter 5 an seiner Unterseite zweckmäßigerweise mit einer Abschrägung 27 versehen.Between the base plate 13 and the central area of the holder 5 is a compression spring 24 (coil spring) clamped in illustrated embodiment in a side, bottom, with a recess 25 provided in the pin 5 of the holder 5 and this biased into a position tilted relative to the ground (Fig. 5), in the key 3 out of its plane and thus perpendicularly out of the plane the swivel circle of the radius actuator 4 is pivoted or tilted out is (see also Fig. 2). To swivel with a low overall height To achieve, the holder 5 is conveniently on its underside bevelled 27.

Ein am Halter 5 befindlicher Vorsprung 28 dient zur Begrenzung des maximalen Kippwinkels, ein Vorsprung 29 des Halters 5 begrenzt den Kippwinkel in der Nullage (Fig. 7).A projection 28 located on the holder 5 serves for limitation of the maximum tilt angle, a projection 29 of the holder 5 limits the Tilt angle in the zero position (Fig. 7).

Die Einstellung des gewünschten Kippwinkels des Schlüssels 3 senkrecht zur Schlüsselebene bzw. senkrecht zur Ebene des Schwenkreises des Radiusbetätigers 4 entsprechend der Einführstellung (Fig. 2) erfolgt über eine mit einem Innensechskant 30 versehene Stellschraube 31, die von einer Bohrung 32 selbsthemmend aufgenommen wird, die sich auf der der Druckfeder 24 abgewandten Seite des Halters 5 befindet. Die Stellschraube 31 ist somit mittels eines Steckschlüssels verstellbar, ohne daß dies durch den Schlüssel 3 behindert wird.The setting of the desired tilt angle of the key 3 perpendicular to the key plane or perpendicular to the swivel rice plane of the radius actuator 4 according to the insertion position (Fig. 2) via a set screw 31 provided with a hexagon socket 30, the is received by a bore 32 self-locking, which is on the the compression spring 24 facing away from the holder 5. The set screw 31 is thus adjustable by means of a socket wrench that this is hindered by the key 3.

Die Bohrung 32 kann wie die Bohrung 21 ausgebildet sein. Die Bohrungen 21 und 32 sind etwa diagonal gegenüberliegend zum Fortsatz 18 des Schlüssels 3 im Mittelteil des Halters 5 angebracht, während die Druckfedern 19, 24 sich benachbart zueinander auf einer Seite des Fortsatzes 18 befinden.The bore 32 can be designed like the bore 21. The Bores 21 and 32 are approximately diagonally opposite to extension 18 of the key 3 attached in the middle part of the holder 5, while the Compression springs 19, 24 are adjacent to one another on one side of the extension 18 are located.

Die Vorsprünge 28 und 29 wirken zusammen mit Ausnehmungen 33 der Abdeckung 6, die diagonal gegenüberliegend angebracht. Durch Drehen des Halters 5 mit dem Schlüssel 3 um 180° ergibt sich die Kippmöglichkeit in entgegengesetzter Richtung.The projections 28 and 29 act together with recesses 33 the cover 6, which is attached diagonally opposite. Go berserk the holder 5 with the key 3 by 180 ° results in the possibility of tipping in the opposite direction.

Der Halter 5 kann anstelle der der Wellenstummel 12 auch entsprechende Ausnehmungen oder Schnapplager zur Aufnahme von Achsstummeln aufweisen, die mit der Abdeckung 6 oder der Bodenplatte 13 verbunden sind, um den Halter 5 kippbar gegenüber der Klappe, dem Deckel od.dgl. anzuordnen.The holder 5 can instead of the stub shaft 12 also corresponding Recesses or snap-in bearings to accommodate stub axles have connected to the cover 6 or the bottom plate 13 are to the holder 5 tiltable relative to the flap, the lid or the like. to arrange.

Die Bodenplatte 13 kann auch durch die Klappe, den Deckel od.dgl. ersetzt sein.The bottom plate 13 can also through the flap, the lid or the like. to be replaced.
