Definitions
- the invention relates to a switch lock for opening and closing contacts of a switching device that a Angle lever for actuating a lock mechanism, a ratchet lever and has an intermediate lever on which the angle lever is latched in the ON position, in which the The intermediate lever is latched by the one provided for release Pawl lever exists.
- a generic switch lock is known. This is an example explained with reference to FIGS 6 and 7.
- FIG 6 shows the switch lock in the ON position, in which the long arm of the intermediate lever latched to a ratchet lever and the latching of the angle lever on the short arm of the Intermediate lever exists.
- the intermediate lever is the angle lever in the triggered Position transferred according to FIG 7.
- the angle lever grips the end of the short arm Intermediate lever and holds it against the one acting on it Return spring force in the position shown.
- the intermediate lever is released and swings in turn back to its starting position.
- DE 38 29 366 A1 there is an electrical switch with a Locking arrangement described.
- the switch points an electronic trigger circuit and also contains a reset spring in cooperation with a shift lock spring, to manually reset the switch an automatic trigger function.
- the Reset spring allows the locking arrangement of the Switch is reset manually at a minimum Path length of the switch operating handle.
- the invention has for its object a switch lock of the type mentioned above with regard to its triggering and Reset from the tripped state to the ON state to improve.
- angle lever has a protrusion that when triggered via a nose formed on the ratchet lever moved its open position. That way it can be dependent the position of the ratchet lever from the position of the bell crank to be influenced. This enables the intermediate lever during a reset to keep rotatable in the desired manner without he latched on the latch lever.
- Switch lock 1 shows a switch lock 1 of a switching device with a Bearing plate 2, an angle lever 3, an intermediate lever 4 and a ratchet lever 5, each on the bearing plate 2 are rotatably mounted.
- Switch lock 1 is located here in the ON position, in which the lower end of FIG Angle lever 3 latched on the short arm of the intermediate lever 4 is.
- With 6, the coupling point of the angle lever 3 with the Lever or lock mechanism not shown here.
- By attacking at the coupling point 6, by the Arrow 7 designated spring force is the rotation of the Angle lever 3 in the OFF position.
- In the ON position according to 1 is the intermediate lever loaded by a return spring 8 4 via the pawl lever 5 at the latching point 17 latched.
- Pawl lever 5 On the one shown here in the closed position Pawl lever 5 is a nose 9 formed on the trigger of the ratchet lever 5, a projection 10 of the angle lever 3 attacks and in this way the pawl lever 5 in his open position moves.
- the latch of the angle lever 3 takes place at the end of a ramp provided on the intermediate lever 4 11.
- FIG. 2 shows a schematic diagram of the lever mechanism with the three bearing points 12, 13 and 15 for the mentioned levers 3, 4 and 5.
- a compression spring 14 holds the latch lever 5 in its closed position according to FIG. 2.
- the angle lever 3 is already on the ramp 11 of the Intermediate lever 4, which is already a small Angle in relation to its starting position over the latching point 17 is turned out. At the same time, the angle lever holds 3 with its projection 10 the pawl lever 5 still in its open position.
