Definitions

  • the invention relates to an actuator for electrical command and signaling devices, in particular emergency stop switches, with a locking device for the operating position, wherein a slide is arranged displaceably in the device housing by means of a push button, furthermore in a transverse breakthrough of the slide under the Locking elements standing under pressure of a spring are provided which cooperate with two locking points incorporated into the housing inner wall at a distance from one another in the direction of displacement.
  • an actuator of the aforementioned type for a push button switch is known from DE-A-32 07 725.
  • the slide has an opening in the form of a transverse bore in which there are two locking balls, which are pressed apart diametrically by a locking spring in the locking recesses provided on the housing.
  • compression springs are inserted in such a way that they always try to move the slide together with the push button from the first locking position to the second locking position in accordance with the operating position.
  • the device is expressly designed in such a way that it should be tamper-proof while avoiding turning the pushbutton, in that the switching operation is only triggered by depressing the pushbutton, after which the switching operation should then be completely uninfluenced from the outside.
  • a locking device for circuit breakers is known from DE-A-31 13 034, which prevents the circuit breaker from being unintentionally switched on again and shows whether the circuit breaker has triggered itself or has been actuated via the emergency stop button.
  • a special construction of a locking slide is provided transversely to the direction of movement of the drive plunger. The locking slide prevents the circuit breaker from being switched on again. To switch it on again, it is necessary to move a drive button to the starting position.
  • the invention has for its object to provide an actuator that only triggers a deliberately strong pressure on the push button and moving the push button over a relatively large distance, which also locks the operating position and makes it visible to the outside, and in which this Returning to the rest position is only possible by an operation that is not immediately obvious.
  • the object is achieved in that the slide is surrounded by a displaceable sleeve which has two mutually opposite transverse bores through which the locking elements designed as hollow pins can pass through, that the breakthrough of the slide is widened in the direction of displacement that between the head of the Slider and the end face of the housing an outer compression spring and the head of Schinbers and the sleeve an inner compression spring are arranged that the second locking points are designed according to the operating position such that unlocking takes place only by turning the push button about its longitudinal axis, and that an actuating body which is displaceable in the displacement direction is connected to the end of the sleeve which is remote from the push button.
  • the actuating attachment explained below is mounted in the exemplary embodiment shown in FIGS. 1 and 2 on a mounting plate 1 which has a hole 2 through which the lower part of the actuating attachment, which is shown in the drawing, can be inserted, namely a threaded attachment 5 and a cylindrical attachment 8, which rests with its outer flange on the outside of the mounting plate 1.
  • the attachment is optionally carried out with the interposition of a washer 3 by means of a nut 4 which is screwed onto the threaded attachment 5.
  • the flange of the cylindrical extension 8 is covered by a collar 6 of the threaded extension 5.
  • the housing base 7 of the housing 9 bears against this collar.
  • the lower part of the housing 9 in the drawing is covered by a cylindrical jacket 73 which merges downwards into a part 74 which is square or round in plan view.
  • the flange of the cylindrical extension 8 and the collar 6 are correspondingly square or adjusted round.
  • a circumferential groove 10 is provided on the circumference, in which an annular bead 11 at the lower edge of a flexible sealing hood 12 is clamped.
  • the other upper edge 13 of the sealing hood 12 is fastened in an annular groove 14 of an inner cylindrical projection 15 of a push button 16, so that the flexible sealing hood, for example made of rubber, closes off all the moving parts of the actuating attachment explained below in a dust-proof manner to the outside.
  • a cavity 23 is received; Part of the sealing hood 12 is provided, in particular for the operating position of the actuator, as can be seen from Fig. 2.
  • a display plate 20 preferably a red plate of an emergency stop switch, is provided, which is provided with locking projections 21 and 22, which in turn engage in recesses 18 and 19. The display plate 20 can thus also be replaced.
  • the push button 16 has a central bore 24, through which a screw 25 is passed and screwed into a threaded bore 28 in the head 27 of a slide 26, so that the push button 16 is firmly connected to the slide 26 and at the same time the upper edge 13 of the sealing hood is tightly clamped, between the cylindrical extension 15 of the push button and the upper shoulder 29 of the head 27 of the slide 26.
  • the slide 26 is surrounded by a displaceable, cylindrical sleeve 36 on the outer circumference, essentially on the lower half of the slide, as can be seen from FIGS. 1 and 2.
  • An external compression spring 31 is inserted between the head 27 of the slide 26, more precisely between a guide recess on the edge of the shoulder 29, and the end face 33 of the housing 9.
  • Another inner compression spring 32 is located between the shoulder 29 of the head 27 of the slide 26 on the one hand and the upper end face of the sleeve 36 in the drawing, an annular recess 35 being provided in this end face of the sleeve 36 for better holding of the lower end of the inner compression spring 32 is incorporated.
  • the guide edge 34 of the housing 9, which protrudes somewhat above the upper end face 33, is used for better guidance of the lower end of the outer compression spring 31.
  • the ends of the compression springs 31 and 32 which are supported on the head 27 of the slide 26 are separated from one another by an annular extension 30, which likewise contributes to an improvement in the mounting of the compression springs.
  • the sleeve 36 has two mutually opposite transverse bores 37 and 38, through which a hollow pin 39 and 40 can reach. As will be explained in more detail below, these hollow pins serve as locking elements.
  • the hollow pins 39, 40 are hemispherically rounded at their outer ends. You will be using a print spring 4l constantly pressed outwards or spread apart, the compression spring engages with its ends as shown in the hollow pins.
  • the hollow pins 39 and 40 are dimensioned so long that they partially engage with their inner ends in an opening 42 of the slide 26 as shown. But they may only be dimensioned so long that they do not meet each other with their inner end faces in the pressed-in state against the force of the compression spring 4 1 .
  • the opening 42 of the slide 26 is widened in the direction of displacement, that is to say upwards in the positions according to FIGS. 1 and 2, while the width of the opening is dimensioned perpendicular to the image planes of FIGS. 1 and 2 such that the hollow pins 39 and 40 are freely movable.
  • the essentially cylindrical slide 26 On a part of its circumference, the essentially cylindrical slide 26 has flattened guide surfaces 43 and 44 which run perpendicular to the image planes of FIGS. 1 and 2.
  • the inner surfaces 45 and 46 of the sleeve 36 are correspondingly flat, so that these surfaces slide on each other, but above all provide a rotation lock between the slide 26 and sleeve 36, so that only a sliding movement in the direction of displacement between the slide and sleeve is not possible but a mutual shift in a direction of rotation about the longitudinal axis.
  • an actuating body 58 is held, which has an outer projecting guide edge 59 for the lower end of the sleeve 36 on its upper end face.
  • the actuating body 58 has strips 60 and 61 leading downwards in FIGS. 1 and 2, the ends of which have outer thickenings 62 and 63. The stroke of the actuating body 58 is thereby limited and by stops 64 and 65 on the inner wall of the threaded attachment 5.
  • the second locking points 52 and 53 are designed according to the operating position according to FIG. 2 in such a way that they can only be unlocked by rotating the push button 16 about its longitudinal axis.
  • An exemplary embodiment of this is shown in detail in FIGS. 3 to 9.
  • the second locking points 52, 53 in the cross section according to FIGS. 5 and 7 have crescent-shaped recesses 67 and 68 widened in the circumferential direction, so that the hollow pins 39 and 40 when the push button 16 is turned from the second locking points to the adjacent part of the cylindrical housing inner wall be pushed back into the sleeve 36 and the slider 26.
  • the crescent-shaped recesses 67 and 68 are expediently provided on the side of the grooves 52 and 53 so that the pushbutton 16 can be turned clockwise in the operating position according to FIG. 2 if the locking is to be released.
  • a further groove 69 which extends in the direction of displacement is provided in the inner wall of the housing 9 and which is at an angle of approximately 90 ° to the grooves 50, 51 and 52, 53 is offset.
  • the groove is provided with an extension 70 trapezoidal, the transition from the extension 70 to the groove 69 being formed by an inclined surface 71 is.
  • a pin 72 is attached to the outside of the sleeve 36, which engages in the groove 69 or extension 70.
  • the operation of the actuator described above is essentially as follows. 1 is in the rest position, the thickenings 62, 63 of the strips 60, 61 abut against the stop projections 64 and 65, so that the uppermost position of the moving parts is thus limited despite a certain preload of the compression springs 31 and 32.
  • the hollow pins 39 and 40 are seated in the first latching position at the lower end of the grooves 50 and 51. If the push button 16 is now pressed down slightly from the position shown in FIG. 1, the compression springs 31 and 32 are more or less compressed and the slider 26 moves down accordingly.
  • the hollow pins 39, 40 are not necessarily taken along with the compression spring 41, so that the hollow pins 39, 40 and the sleeve 36 initially remain unchanged in the initial position. If the push button 16 is released after tapping or after a slight shift, it returns to the original position without triggering or any switching operation taking place.
  • the stroke of the sleeve 36 and the actuating body 58 is limited by the stop projections 64 and 65, ie the shoulder surface 66 of the actuating body 58 then lies against these stop projections 64, 65 in accordance with the position according to FIG. 2.
  • the hollow pins 39, 40 can spread again by the action of the compression spring 41, so that they are in the second locking position at the upper end of the grooves 52, 53 according to FIG. 2.
  • a return of the moving parts and the push button 16, which in this position indicates that the switching process has taken place, can be done neither by pressing again or by pulling back the push button, since the hollow pins on the described lower surfaces of the projections 64 and perpendicular to the direction of displacement 65 concerns.
  • the ring extension 30 explained above not only has the task of separating the ends of the compression springs 31 and 32 from one another or intervening between them, but rather this ring extension has the following essential meaning. If it should happen that one or the other compression spring 31 or 32 jams, decreases in the spring force or even breaks, the actuating attachment according to the invention is not ineffective, rather the ring extension 30 then comes to the effect that it meets with its front free end when pressing the push button on the upper end face of the sleeve 36 in the drawing and forcibly drives it down, so that the switch-off in any case, for example, with an emergency stop switch he follows.
