Definitions
- the present invention relates to a radius actuator for safety switches, consisting of a holder and one against spring force between one inclined approach position and a switch actuation position movable therein held operating bracket, the operating bracket on its inside of the holder lying end carries a ball.
- Safety switches are used in general to switch off the Power supply when, for example, a protective cover from a device or is removed from a machine, cabinet doors, room doors or the like be opened.
- Such safety switches usually have several, in different Direction-oriented approach openings, through the actuation bracket for the purpose of switching can kick, for example, together with a door, one Flap or the like moves.
- the radius actuator is on the flap, Door, cover or the like in a predetermined position from the flap or Axis of rotation of this part attached.
- Radius actuators of this type are used if insofar as the safety switch of the actuators on the door, flap or cover only open a small swivel radius can be arranged.
- the design is to make so that the radius actuator in the start-up phase to Safety switch is in an inclined position (approach position) so that it is at small swivel radius easily into the safety switch or its Approach opening can occur, but it continues in the course of Switch actuation for the actuation of, for example, a ratchet wheel
- a safety switch essentially to be operated Element can assume vertical switch actuation position.
- the spring force ensures that the actuating bracket of the radius actuator after Leaving the safety switch returns to the approach position.
- the present invention has for its object a radius actuator to create the generic type, the total of proportionately there are few individual parts and its operating bracket with respect to its Basic position relative to the holder is easily adjustable and fixable.
- the radius actuator according to the present invention consists of an extreme small number of individual parts and is still all described above Requirements for such a radius actuator.
- the basic setting of the operating bracket is after a slight loosening of the screws connecting the halves of the clamping part made what by leading into the hollow chamber of the holder Mounting bores is possible with a completely assembled radius actuator. After the desired basic setting is found, the two Screws tightened so that the operating bracket with his Shaft, the ball provided at the end of the shaft and the clamping part forms a structural unit within certain limits with respect to the longitudinal axis of the shaft can be pivoted.
- a particularly advantageous embodiment of the radius actuator exists in that the holder in the passage area of the shaft with two intersecting guide slots for the shaft of the operating bracket is.
- the radius actuator designated by reference number 1 essentially consists of a holder 2 and one movable therein against spring force Operating bracket 3.
- the actuating bracket 3 is equipped with a shaft 4 which extends into a hollow chamber 5 of the holder 2 protrudes and carries a ball 6 at its end there.
- the ball 6 is fixed within a pipe clamp-like clamping part 7 clamped.
- the pipe clamp-like clamping part 7 consists of two by screws 8 interconnected halves 7a and 7b, which is particularly shown in FIG. 3 shows particularly clearly.
- the end face 9 of the clamping part 7 facing away from the actuating bracket 3 is by a spring 10 located within the hollow chamber 5 of the holder 2 acted on, the other end of the hollow chamber 5 of the Holder 2 supporting cover 11 supports.
- the holder 2 is in the passage area of the shaft 4 with two intersecting guide slots 12 and 13 for the Leadership 4 equipped.
- Figure 3 illustrates that the holder 2 with two mounting holes 14th is equipped, each open into the hollow chamber 5 of the holder 2 and lie in alignment with the screws 8 of the clamping part 7.
- the hollow chamber 5 is advantageously approximately square in its outline trained, the same applies to the outer contour of the clamping part 7, so that a Rotation of the clamping part 7 within the hollow chamber 5 is excluded.
