Definitions
- the present invention relates to a radius actuator for safety switches, consisting of a holder and a spring force between a oblique starting position and a switch operating position movable therein held operating bracket, wherein the operating bracket at its inside the holder lying end carries a ball.
- Safety switches are generally used for the forced shutdown of Power supply, for example, when a protective cover of 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 Directions oriented approach openings, by the purpose of switching an operating handle can occur, for example, together with a door, a Flap or the like moves.
- the radius actuator is at the flap, Door, cover or the like in a predetermined state of the flap or Fastened axis of rotation of this part.
- Such radius actuators are then used, if so far in relation to the safety switch of the actuator on the door, flap or lid only on a small swivel radius can be arranged.
- the design is to make it so that the radius actuator in the starting phase for Safety switch has a sloping position (starting position), so that he at Small swivel radius easily in the safety switch or its Anfahrö réelle may occur, but he in the further course of Switch operation for the operation of a ratchet wheel, for example
- Such safety switch a substantially to be operated Element vertical switch actuation position can take.
- the spring force ensures that the actuating bow of the radius actuator after Leaving the safety switch again assumes the starting position.
- the present invention is based on the object, a radius actuator of the generic type to create the total of relatively consists of few items and whose operating handle with respect to his Basic position relative to the holder easily adjustable and fixable.
- the actuating bracket a protruding into the holder and at its local end bearing the ball Shank has that the ball in one of two by screws with each other connected halves existing, clamp-like clamping part firmly is clamped, which lies in a hollow chamber of the holder and on his the actuator facing away from an end on the other hand on the holder supported spring is applied and that the holder with two in the Hollow opening and aligned with the screws of the clamping part Mounting holes is provided.
- the radius actuator according to the present invention consists of an extremely small number of items and is still all initially described Requirements for such a radius actuator fair.
- the basic setting of the actuating yoke is after a slight release of the the halves of the clamping part interconnecting screws made, which by leading into the hollow chamber of the holder Mounting holes in completely assembled radius actuator is possible. After the desired basic setting is found, the two become Tightened screws so that now the operating handle with his Shank, which provided at the end of the shaft ball and the clamping part forms a structural unit, which within certain limits with respect to the shaft longitudinal axis can be pivoted.
- a particularly advantageous embodiment of the radius actuator exists in that the holder in the passage region of the shaft with two itself provided crossing guide slots for the shaft of the actuating bracket is.
- Reference numeral 1 designated radius actuator consists essentially of a holder 2 and a spring force held therein movable Operating handle 3.
- the actuating bow 3 is equipped with a shaft 4, which into a hollow chamber 5 of the holder 2 projects and carries at its local end a ball 6.
- the ball 6 is fixed within a clamp-like clamping part 7 clamped.
- the clamp-like clamping part 7 consists of two screws 8 halves 7a and 7b connected to one another, which is particularly shown in FIG. 3 shows very clearly.
- the actuating bracket 3 facing away from the end face 9 of the clamping member 7 is by a spring 10 located inside the hollow chamber 5 of the holder 2 acted upon, with its other end to a hollow chamber 5 of the Holder 2 occlusive lid 11 is supported.
- the holder 2 is in the passage region 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 opening into the hollow chamber 5 of the holder 2 and lie in alignment with the screws 8 of the clamping part 7.
- a mechanic can by the Mounting holes 14, the screw of the two halves 7a and 7b of the Slightly loosen clamping part 7 and in this position the basic position of the Actuator bracket 3 relative to the holder 2 corresponding to the two Adjust the axial directions of the guide slots 12 and 13. Is the desired Basic setting reached, the two screws 8 are tightened, so that now the clamping member 7 with the ball 6, the shaft 4 and the Operating handle 3 forms a rigid unit. This entire unit can then from the preset starting position of the actuating bracket 3, as in 4, until they are pivoted into a switch actuation position, as drawn in Figure 5. If the radius actuator then again moved out of the operating opening of a safety switch, takes the Operating handle 3 again his Anfahr too according to Figure 4 a.
- the hollow chamber 5 is approximately square in plan formed, the same applies to the outer contour of the clamping member 7, so that a Rotation of the clamping part 7 is excluded within the hollow chamber 5.
