Definitions

  • the present invention relates to a radius actuator for safety switches, consisting of a holder and an actuating bracket that is movably held therein between an oblique approach position and a switch actuating position.
  • Safety switches are used for forcibly switching off the power supply, for example on machines with a protective cover on housing doors, room doors or the like.
  • Safety switches of this type usually have a plurality of approach openings oriented in different directions through which, for the purpose of switching, an actuator can move which, for example, moves together with a door, a flap or the like.
  • the radius actuator is attached to the flap, door, cover or the like at a predetermined distance from the folding or rotating axis of this part.
  • Radius actuators of the generic type are used when, in relation to the safety switch, the actuator on the door, flap or cover only on one small swivel radius can be arranged. Care must be taken that the radius actuator is in an inclined position (approach position) in the start-up phase to the safety switch, so that it can easily enter the safety switch or its start-up opening with a small swivel radius, but it can, for example, operate as the switch is actuated of a switching wheel of such a safety switch can assume a switch actuation position which is essentially perpendicular to the element to be actuated. The spring force ensures that the actuating bracket of the radius actuator returns to the starting position after leaving the safety switch.
  • the present invention has for its object to improve a radius actuator of the generic type with simple means to the effect that its actuating bracket can be preset in an inclined starting position according to all conceivable applications.
  • the actuating bracket is attached to one end of a supporting part, the other end of which projects into the holder, that the actuating bracket can be pivoted about a pivot axis relative to the supporting part and can be fixed in any possible pivoting position relative to the supporting part, that the supporting part with its end protruding into the holder attached to a base plate and pivotable relative to this base plate about a second pivot axis and can be fixed in any possible pivot position relative to the base plate, the second pivot axis being offset by 90 degrees from the support part and actuating bracket and that Base plate within the holder against the action of a spring supported in the holder in the direction of the longitudinal axis of the support member is displaceable and tiltable within limits with respect to this longitudinal axis.
  • a radius actuator designed in this way can be preset in accordance with any conceivable application in such a way that its actuating bracket has the desired or required oblique approach position.
  • the radius actuator for safety switch shown in the drawings consists essentially of a housing-like holder 1 and an actuating bracket 2 mounted therein against spring force between an oblique starting position and a switch actuating position, the actuating bracket 2 being fastened to a supporting part 3, the other end of which is attached to the support element 3 Holder 1 protrudes.
  • the support part 3 is formed in the connection area to the operating bracket 2 in the manner of a fork head 4, this fork head 4 having a receiving slot 5 for the operating bracket 2.
  • a bore 6 runs transversely to this slot 5 and is assigned a corresponding through bore 7 in the actuating bracket 2.
  • a pin 8 is guided through the bore 6 and the receiving bore 7, about which the actuating bracket 2 can be pivoted relative to the supporting part 3.
  • a clamping screw 9 is passed through the fork head 4 and passes through the actuating bracket 2 in the region of an arcuate elongated hole 10.
  • the fork head 4 can be clamped together perpendicular to the slot 5 and thus the actuating bracket 2 can be clamped and fixed in the fork head 4.
  • the actuating bracket 2 can be pivoted about the pin 8 forming a pivot axis within limits relative to the longitudinal axis of the support part 3 and can be fixed in any possible pivot position relative to the support part.
  • the end of the support part 3 protruding into the housing-like holder 1 is fixed to a base plate 11 and can be pivoted about a second pivot axis 12 relative to this base plate 11 and can be fixed in any possible pivot position relative to the base plate 11.
  • the pivot axis 12 corresponds to the longitudinal axis of a screw 13 which passes through the base plate 11 and a bore 14 of the support member 3.
  • the base plate 11 has a central cutout 15 into which the end of the support part 3, which is on the holder side and provided with the bore 14, projects. Within this recess 15, the holder end of the support member 3 can be clamped in any possible pivot position.
  • the second pivot axis 12 is offset by 90 degrees to the pivot axis between the supporting part 3 on the one hand and the actuating bracket 2 on the other.
  • the base plate 11 is acted upon by a spring 16 within the holder 1 in the direction of the longitudinal axis of the support part 3. Furthermore, the base plate 11 is axially displaceable within the holder 1 in a recess 17 designed in accordance with the square outline of the base plate 1, but is not rotatable.
  • the base plate 11 is dimensioned so that there is the possibility of tilting the base plate 11 within this recess 17 with respect to the longitudinal axis of the support part 3.
  • the spring 16 is supported on the one hand on the base plate 11 and on the other hand on a disk 18 closing the holder 1.
  • the supporting part 3 can be fastened to the base plate 11 perpendicular to the latter.
  • the actuating bracket 2 is fastened to the supporting part 3 in a relative pivoting position, as shown in FIG. 6.
  • Figures 4 and 6 each show the so-called approach position, i. H. the position in which the entire radius actuator is outside of a safety switch.
  • the actuating bracket 2 Corresponding to the respective inclined position of the actuating bracket 2, it can be moved into a safety switch and is then ultimately moved from the starting position shown in the drawings into a switch actuation position, a switch actuation position being shown in FIG. 3.
  • the base plate 11 is tilted within the holder 1, the starting position shown in FIG. 4 being brought back again by the spring 16 when the radius actuator is separated from a safety switch, in that this spring 16 brings the base plate 11 back into place moved back to their basic position.
