Abstract

The invention relates to an actuator element for setting the position of a target mark of a sighting telescope having a front module and a rear module, and the front module and rear module are connected to one another by means of a coupling mechanism, which coupling mechanism can be manually actuated in order to separate the front module from the rear module.

First claim

The invention claimed is:

1. An actuator element for setting the position of a target mark of a sighting telescope having a front module and a rear module, wherein the front module and rear module are connected to one another by a coupling mechanism, which coupling mechanism can be manually actuated in order to separate the front module from the rear module, wherein a locking hub is rotatably mounted in the rear module and the rear module comprises a lock housing, a positioning ring and a threaded ring forming a bearing for the locking hub, wherein the front module comprises an intermediate housing and a setting knob mounted on the intermediate housing, the setting knob being rotatable relative to the intermediate housing, wherein when the front module is in a state attached to the rear module the intermediate housing constitutes a stationary housing part, in that the intermediate housing is in a rotation preventing engagement with the positioning ring.

2. The actuator element according to claim 1 , wherein in order to indicate a pre-definable position of the target mark, the front module comprises a scale and the rear module comprises a zero index.

3. The actuator element according to claim 1 , wherein the front module comprises a carrier sleeve and the scale is applied to the carrier sleeve.

4. The actuator element according to claim 3 , wherein at least one index element for indicating a pre-definable position of the target mark is secured to the carrier sleeve so as to be prevented from rotating relative to it.

5. The actuator element according to claim 3 , wherein the rear module comprises a lock housing, a spindle mounted in the lock housing so as to be rotatable about an axis of rotation and a locking hub rotatable about the axis of rotation for moving the spindle.

6. The actuator element according to claim 5 , wherein the carrier sleeve is coupled in rotation with the locking hub.

7. The actuator element according to claim 5 , wherein the coupling mechanism constitutes a part of a locking mechanism and the locking mechanism comprises a tensioning system with pre-tensioned springs.

8. The actuator element according to claim 7 , wherein the locking mechanism comprises a control element which is actively connected to the tensioning system, and when the control element is operated, the connection between the front module and rear module can be released.

9. The actuator element according to claim 8 , wherein the control element of the locking mechanism is provided in the form of a push-button.

10. The actuator element according to claim 7 , wherein the tensioning system of the locking mechanism comprises sleeves which are disposed coaxially with the axis of rotation and which are able to slide one inside the other.

11. The actuator element according to claim 9 , wherein the locking mechanism comprises a carrier sleeve and a locking sleeve which is able to slide in the carrier sleeve, and at least one radially extending tunnel is provided in a bottom end region of the locking sleeve, and at least one retaining ball is disposed in the tunnel and the at least one retaining ball is able to move to and fro in the radial direction.

12. The actuator element according to claim 11 , wherein the locking sleeve has at least one axially extending slot and the carrier sleeve has at least one pin engaging with the slot.

13. The actuator element according to claim 11 , wherein the locking hub comprises a top tube portion having a circumferentially extending groove in an internal face.

14. The actuator element according to claim 13 , wherein the coupling mechanism comprises at least the locking sleeve with the retaining balls and the top tube portion of the locking hub with the groove.

15. The actuator element according to claim 13 , wherein when the front module and rear module are in the connected state, the bottom end region of the locking sleeve is accommodated in the top tube portion of the locking hub, and the at least one retaining ball is lodged in the groove of the locking hub.

16. The actuator element according to claim 13 , wherein the locking mechanism comprises an outer clamping sleeve and a first outer compression spring and the first outer compression spring is disposed and held clamped between the carrier sleeve and the outer clamping sleeve.

17. The actuator element according to claim 16 , wherein the locking mechanism comprises an inner clamping sleeve and a second inner compression spring and the second inner compression spring is disposed and held clamped between the locking sleeve and the inner clamping sleeve.

18. The actuator element according to claim 17 , wherein when the front module and rear module are in the connected state, a bottom end region of the inner clamping sleeve lies against the at least one retaining ball and holds it lodged in the circumferentially extending groove of the locking hub.

19. The actuator element according to claim 17 , wherein the inner clamping sleeve has a circumferentially extending groove in an external face and in an intermediate position when separating the front module and rear module, the at least one retaining ball is at least partially accommodated in the circumferentially extending groove of the inner clamping sleeve.

20. The actuator element according to claim 17 , wherein when the front module and rear module are in a separated state, the at least one retaining ball is retained in its radial position in the tunnel by means of a narrowed region in the outer end region of the tunnel.

21. The actuator element according to claim 11 , wherein the carrier sleeve has an outwardly projecting top disk portion at a top end region which is connected to the carrier sleeve, and the disk portion is screwed into the carrier sleeve by means of a thread.

22. The actuator element according to claim 17 , wherein a threaded ring is secured in the top end region of the carrier sleeve, by means of which the inner clamping sleeve is held clamped with the second inner compression spring.

23. The actuator element according to claim 17 , wherein the push-button is connected to the inner clamping sleeve via an interconnected compression spring.

24. The actuator element according to claim 23 , wherein the push-button comprises an axle pin which is provided with a slot and catch lugs, and the catch lugs are latched onto an inwardly extending projection of the inner locking sleeve.

25. The Actuator element according to claim 23 , wherein the push-button is held fixed in a maximum raised position by means of the compression spring disposed between the inner clamping sleeve and the push-button.
