Abstract

A quick-release device for clamping a quick-change plate of an optical device in a guide on a baseplate, the quick-change plate and the guide comprising complementarily formed guide surfaces, the guide comprising first and second mounting elements adjustable relative to each other, and a device for fixing the quick-change plate in place designed for adjusting the distance of the mounting elements to each other, characterized in that the device for fixing the quick-change plate in place comprises a lever engaging with a earn in a slotted link disposed in the first mounting element, such that a motion of the lever adjusts the first mounting element relative to the second mounting element.

Claims

1. Quick change plate-quick clamping apparatus comprising:

a guide on a base plate for clamping a quick change plate of an optical device into the guide, wherein the quick change plate and the guide have complementarily formed guide surfaces, the guide has first and second retaining elements, which can be adjusted relative to each other, and

an apparatus is provided for fixing the quick change plate, which is formed to adjust the distance of the retaining elements with respect to each other, wherein the apparatus for fixing the quick change plate includes a lever which engages with a cam in a slotted link which is disposed in the first retaining element in such a way that a movement of the lever adjusts the first retaining element relative to the second retaining element,

wherein, in a first position, the lever fixes the optical device, in a second position, the lever releases the optical device for displacement in the guide, and, in a third position, the lever releases the optical device for removal, and the slotted link is provided with an aperture at one end in order to receive the cam in the fixing position.

2. Quick clamping apparatus as claimed in claim 1, wherein the second retaining element is formed by the guide and its guide surface which rise on one side of the base plate.

3. Quick clamping apparatus as claimed in claim 1, wherein the second retaining element has an undercut.

4. Quick clamping apparatus as claimed in claim 1, wherein the second retaining element is formed in a stationary manner.

5. Quick clamping apparatus as claimed in claim 1, wherein the first retaining element includes a block which can move in the adjustment direction and which is formed with a guide surface on one long side.

6. Quick clamping apparatus as claimed in claim 1, wherein the first retaining element has an undercut.

7. Quick clamping apparatus as claimed in claim 1, wherein the second retaining element forms, together with the first retaining element, a dove-tailed guide surface.

8. Quick clamping apparatus as claimed in claim 5, wherein the block is spring-biased in the adjustment movement.

9. Quick clamping apparatus as claimed in claim 5, wherein the block is moveably received in a guide.

10. Quick clamping apparatus as claimed in claim 9, wherein the guide of the movable block is formed by a cover, lateral protrusions and an indentation in the base plate.

11. Quick clamping apparatus as claimed in claim 10, wherein the cover is flexible.

12. Quick clamping apparatus as claimed in claim 1, wherein the lever is a two-armed angle lever,

13. Quick clamping apparatus as claimed in claim 1, wherein the cam is produced from an elastic material.

14. Quick clamping apparatus as claimed in claim 1, wherein the slotted link is provided with an aperture disposed approximately centrally in the longitudinal direction, in order to receive the cam in the displacement position.

15. Quick clamping apparatus as claimed in claims 1 including a quick change plate for an optical device, characterised in wherein the base plate of the quick clamping apparatus is provided with knobs at each end of the guide.

16. Quick clamping apparatus as claimed in claim 1, wherein the second retaining element is formed by the guide and its guide surface which rise on one side of the base plate, and wherein the second retaining element has an undercut.

17. Quick clamping apparatus as claimed in claim 16, wherein the second retaining element is formed in a stationary manner.

18. Quick clamping apparatus as claimed in claim 16, wherein the first retaining element includes a block which can move in the adjustment direction and which is formed with a guide surface on one long side, and wherein the first retaining element has an undercut.

19. Quick clamping apparatus as claimed in claim 1, wherein the first retaining element includes a block which can move in the adjustment direction and which is formed with a guide surface on one long side, and wherein the first retaining element has an undercut.

20. Quick clamping apparatus as claimed in claim 19, wherein the block is spring-biased in the adjustment movement, and wherein the block is moveably received in a guide.

21. Quick clamping apparatus as claimed in claim 20, wherein the guide of the movable block is formed by a cover, lateral protrusions and an indentation in the base plate.
