Description

η einen Hebelarm eines Doppelhebels 9, der in lern an der Unterseite des Abdeckrahmens 1 beitigten abgewinkelten Blechstreifen 10 gelagert ist. e Lagerung ist zapfenlos so ausgebildet, daß der )ppelhebel an der Lagerstelle gegenüberliegende nschnitte aufweist und damit im Blechstreifen 10 einer entsprechend bemessenen Aussparung auftiommen ist. Zum Einbringen des Doppelhebels 9 die Aussparung im Blechstreifen oberhalb der ',entliehen Lagerstelle entsprechend erweitert ausbildet. η a lever arm of a double lever 9, which participated in learning on the underside of the cover frame 1 angled sheet metal strip 10 is mounted. e storage is designed without a pin so that the ) has opposite sections at the bearing point and thus in the sheet metal strip 10 a correspondingly dimensioned recess is available. For inserting the double lever 9 the recess in the sheet metal strip above the 'borrowed storage location is expanded accordingly.

An dem dem Stößel 7 abgewandten zweiten ;belarm des Doppelhebels 9 greift eine als Zugier ausgebildete Feder 11 an, deren anderes Ende ι unteren Ende des Blechstreifens 10 befestigt ist. enn durch öffnen des Gehäusedeckels 3 der 5ßel 7 angehoben und schließlich sein Ende von m zugeordneten ersten Hebelarm abgehoben wird, nn der freie zweite Hebelarm kraftschlüssig auf eine Schalttaste eines Schaltorgans 12 einwirken, das dann in Ausschaltstellung gebracht wird (gestrichelt dargestellt). Um zu erreichen, daß der freie zweite Hebelarm bei seiner Schwenkbewegung die Schalttaste funktionssicher betätigt, ist dieser Hebelarm zweckmäßig in einer gabelförmigen Führung 14 geführt. Das Schaltorgan 12 ist als Momentschalter ausgebildet und einstellbar, gesondert an einer Halterung 13 befestigt, die ihrerseits an dem Abdeckrahmen 1 befestigt ist.On the second lever arm of the double lever 9 facing away from the plunger 7, a puller engages formed spring 11, the other end ι lower end of the sheet metal strip 10 is attached. hen by opening the housing cover 3 of the 5ßel 7 is raised and finally its end of m associated first lever arm is lifted, nn the free second lever arm non-positively a switch button of a switching element 12 act, which is then brought into the switch-off position (dashed line shown). In order to ensure that the free second lever arm hits the switch button during its pivoting movement When actuated in a functionally reliable manner, this lever arm is expediently guided in a fork-shaped guide 14. The switching element 12 is designed as a momentary switch and is adjustable, separately on a holder 13, which in turn is attached to the cover frame 1.

Durch den zwischen Stößel 7 und Schaltorgan 12 in Wirkverbindung angeordneten Doppelhebel 9 ist es möglich, das Schaltorgan 12 außerhalb des Wirkbereiches des Deckelscharniers anzuordnen, wodurch sich eine größere Konstruktionsfreiheit ergibt. Hemmungen der Stößelbewegung, etwa durch Verschmutzung, können sich auf den Schaltvorgang nicht auswirken, da der Stößel zwangläufig mit dem Gehäusedeckel bewegt wird.The double lever 9, which is arranged in operative connection between the plunger 7 and switching element 12, is it is possible to arrange the switching element 12 outside the effective area of the lid hinge, whereby there is a greater freedom of design. Inhibition of the slide movement, e.g. due to contamination, cannot affect the switching process, as the plunger inevitably connects to the housing cover is moved.

Finally, by the German utility patent claim: pattern 18 44 315 a safety device

known on spin dryers, also on

Safety device for electrically operated housing cover a cam is attached, which

bene washing, rinsing and spinning devices with 5 actuated a switching pin, which is straight and straight

one sealed by hinges on the device housing through the cover frame into the interior of the housing

steered housing cover, which is guided with a switch and when moving the cover against

member is connected, which acts through the cover a motor switch. So that this well-known

frame of the device sealed against water in the device not actuated with the lid open

the inside of the housing is guided and can be io when moving, is an additional locking cam

of the cover a switching element is required for the drive. It also has the same disadvantages

The device's motor is actuated, as indicated by the device according to DT-Gbm 17 90426

records that the switching element is a straight line.

The invention is based on the object of creating an elongated hole running transversely to the ram axis, in which the 'points and which in a recess (6) of the one switching means, which are arranged in guides and the hinge parts (2) attached to the cover, which therefore protrude more when dirty, with the elongated hole having to be reckoned with friction ,
Axis (4) arranged pin (5) penetrated 20 This is achieved according to the invention in that is, and that the plunger (7) when closing the switching element is a linearly guided plunger housing cover (3) against the force of a with a head, the a spring (11) transversely to the plunger axis against a lever arm of a double-running elongated hole and which is displaceable into a lever (9), the other recess of the one of the flock lever arm attached to the cover for actuating the switching element (12) protrudes 25 kidney parts , whereby the elongated hole is used by one. . is penetrated on this hinge part parallel to the axis of rotation arranged pin, and

"that the plunger when closing the housing cover

can be displaced against the force of a spring against a lever arm of a double lever, the other of which Lever arm for actuating the switching element

The invention relates to a safety device.

For electrically operated washing, rinsing and spinning, there is one of the devices with a housing cover linked to a counter housing by hinges on the device, which is connected to the housing cover with the housing cover in both directions by being connected to a switching element, which is provided by the housing cover with the pin, which is sealed against water with the cover frame of the device in the provided on the plunger, a movement is guided across the inside of the housing and when moving to the plunger longitudinal axis permitting head in the form of the cover a switching element for the drive motor coherent connection stands. The device thus created is actuated. 40 fene articulated connection, which in addition to the movement from the German utility model in the axial direction of the plunger also a transverse to it 17 90 426, a safety device for this movement of the type arranged on the cover is known, in which the switching element allows against a pin without opening the form fit The guided tappet presses which, in the opposite direction, acts in both directions of adjustment of the tappet, safely acted upon by a spring, the simple longitudinally displaceable position being struck. This tappet can only be maintained in a weighting and sealing,
direction of movement of the housing cover inevitably The invention will be activated in the following on the basis of one, so that when the tappet guide is soiled in the drawing, such frictional forces can occur that explained in more detail
the plunger return is not guaranteed and 50 In the drawing, the cover frame 1 denotes the machine with the lid open, a washing machine on which can be used. Hinge parts 2, a housing cover 3 is arranged, furthermore, from the German patent specification with which the tub of washing 8 53145, not shown, a safety device is known when the machine is closed. The hinges have a cam attached to the cover of a washer-dryer 55 next to a rotary axis 4, which is subdivided, and which, when the cover is moved, additional, parallel, outside of the rotary axis movement, a switching element for the motor circuit or pin 5 on, which penetrates a recess 6 of an electromagnetically ventilated braking device of the hinge part 2. Actuated on this Zapdirekt, which in the device housing near the fen 5, a plunger 7 is articulated, the head of which is arranged on a lid hinge. The disadvantage here is that the slot serving for receiving the pin on the one hand has the switching element in the active area of the. This elongated hole enables a form-fit cam to be arranged on the housing cover and, in spite of the cover pivoting movement, a slot-shaped breakthrough must be seen on the cover for the pivotable cam in the guided movement of the plunger in the coaxial housing cover, despite the pivoting movement of the cover, whereby water to the switching element 65 frame 1 and in this itself. The round can reach and under certain circumstances an inadmissible switching on of the switching element is possible by means of a separate tool that is watertight through sealing washers 8. of the vat and acts with its free end
