Definitions

  • the invention relates to a locking arrangement for two switching devices, which are coupled via a locking body in such a way that when a switching device is actuated, the other switching device acting in the opposite sense on the locking body is locked in its actuating movement, the essentially heart-shaped locking body with the tip of the heart in a guide housing which can be fastened separately from the switching devices is guided, the heart wings being operatively connected to the actuating means of the switching devices via plunger and adjusting means.
  • the guide housing is firmly screwed to the mounting plate via a U-bracket.
  • the switching devices here contactors, are provided with two-armed levers which are pivotally connected to the actuating means of the contactor between a support point on the contactor housing and the connection with the plungers guided in the guide housing. Adjustment screws are provided on the ends of the levers connected to the tappets, which can be secured with locknuts.
  • the heart-shaped locking body is suspended from a spring in the guide housing. Due to the spring here, however, a certain amount of play cannot be switched off, so that relatively large distances for the plunger have to be accepted, which is achieved by the elaborately arranged levers.
  • the invention is therefore based on the object of providing an arrangement of the type mentioned above which can be used in a versatile manner with a simple structure without lever transmission and simple adjustment possibility.
  • the adjusting means consist of collar screws screwed into slides guided in the guide housing, which are rigidly connected to the tappets via their collar in the direction of movement and that the heart wings are essentially rigidly connected to the tappets via drivers in the direction of movement .
  • a simple connection of the slide to the actuating means can be achieved if the slides are positively coupled via approaches which engage in the actuating means of the switching devices.
  • feet which are adjustable in length are arranged on the guide housing, it being possible for the feet to be easily attached if they can be pivoted into a toothing of the guide housing prior to attachment to the mounting plate and the feet are fitted with a C- gripping part of trapezoidal form of the two-part guide housing, it is possible to dispense with connecting means of the housing parts.
  • the height adjustment in relation to different contactors can be achieved here in a simple manner in that the feet on the bottom of the C-shaped part and the trapezoidal projections on the surface facing away from the housing are provided with locking teeth.
  • a simple coupling between the plunger and locking body, which is effective in both directions of movement, can be achieved if the drivers are H-shaped and are inserted transversely to the direction of movement into adapted recesses in the plunger and locking body.
  • the locking arrangement 1 is fastened on the mounting plate 2 between two contactors 3 and 4.
  • feet 5 are used, which - as shown in FIG. 3 - can be pivoted into a toothing 6 before assembly.
  • the setting position is indicated by dashed lines in FIG.
  • the length of the feet 5 determines the point of engagement of the extension 9, which engage in the actuator (not shown in more detail) for the contactors 3, 4.
  • the feet can also be formed with a C-shaped part 30, as shown in FIG. 19.
  • This C-shaped part can connect trapezoidal projections 31 of the two guide housing parts 8a and 8b to one another, as shown in FIG.
  • the projections 31 can here be formed on the side facing away from the guide housing with a toothing as a toothed strip, which cooperate with further catches provided on the bottom of the C-shaped part 30.
  • the heart-shaped locking body 10 is guided with the heart tip 11 on the locking curve 12 in the guide housing 8. Furthermore, the slide 13 and the plunger 14 are slidably mounted in the guide housing. The slides 13 engage with the lugs 9 through guide slots 15 in the two halves of the guide housing 8. A lateral projection 16 on the slide 13 serves for connection to the respective plunger 14.
  • the collar screw 17 is used for this purpose. The collar 18 is inserted into a laterally open recess 19 of the plunger 14 after it is self-tapping Screw was screwed into the hole 20 in the formation 16.
  • an H-shaped driver 22 is provided, which is inserted with one of the H-arms 23 into a hammer head-shaped recess 24 in the plunger 14 transversely to the direction of actuation.
  • the other H-arms 23 are inserted into a corresponding recess 25 in the heart wings 26 and in such a way that the web 27 of the heart shape can be passed through the slot 28 in the heart wing 26.
  • the connection is made in such a way that the plunger 14 slide on the curved surface 29 when the locking body moves and this more or less in both directions of movement of the plunger 14. This positive connection of the slide 13, plunger 14 and locking body 10 pulls the locking body back into the central position without the need for an additional spring.
  • the locking body 11 is also removed from the locking curve 12, ie the heads of the collar screws come out through the actuation holes 21 of the guide housing.
  • the length of the collar screws 17 is now chosen such that after screwing in the collar screws in the direction of the mounting surface of the locking arrangement until the surface of the head is flush with the surface of the guide housing, the cancelled correct position of the heart-shaped locking body 10 to the locking curve 12 is present, as can be seen for example from FIG.
