Abstract

Hand lever, preferably produced from plastics material, for operating a valve, preferably a butterfly valve or a ball valve, including a lever and a locking plate, wherein the lever comprises a locking element and a lever upper part, wherein a fastening element for fastening on a valve and for connection to the locking plate is arranged on the lever upper part and the locking plate comprises a receiving opening for receiving the fastening element, characterized in that the receiving opening is realized in an oval manner and the fastening element comprises a round cross-sectional area or the fastening element comprises an oval cross-sectional area and the receiving opening is realized in a round manner, wherein the oval and round contour of the receiving opening preferably comprises at least one recess or slot.

First claim

What is claimed is:

1. A hand lever produced from plastics material for operating a valve including a lever and a locking plate, the lever comprising:
a locking element and a lever upper part,
wherein a fastening element for fastening on a valve and for connection to the locking plate is arranged on the lever upper part and the locking plate comprises a receiving opening for receiving the fastening element,
wherein one of the receiving opening and the fastening element is oval without a straight edge, and a different one of the receiving opening and the fastening element includes a round cross-sectional area,
wherein the receiving opening includes at least one recess or slot, and
wherein the hand lever is connected to the locking plate by way of cooperation between the fastening element and the receiving opening with the fastening element seated within the receiving opening.

2. The hand lever according to claim 1 , wherein at least two cams are arranged on the fastening element and they are arranged offset to one another.

3. The hand lever according to claim 2 , wherein the cams are situated opposite one another.

4. The hand lever according to claim 2 , wherein the at least two cams are offset to one another by 45°-180°.

5. The hand lever according to claim 1 , wherein the oval contour of the receiving opening is formed by two circular contours which are arranged eccentrically to one another.

6. The hand lever according to claim 5 , wherein the two circular contours comprise the same radius.

7. The hand lever according to claim 1 , wherein the oval contour is realized as an elongated hole.

8. The hand lever according to claim 1 , wherein the locking plate comprises at least one stop in the region of the receiving opening for limiting the rotation of the lever.

9. The hand lever according to claim 8 , wherein the locking plate comprises at least two stops in the region of the receiving opening for limiting the rotation of the lever, the one stop limits the fully open state of the valve and the other the completely closed state of the valve.

10. The hand lever according to claim 1 , wherein the locking plate comprises a gearing on the outer circumference.

11. The hand lever according to claim 10 , wherein the gearing is arranged over a region of a circular segment of the outer circumference.

12. The hand lever according to claim 1 , wherein at least one cam for latching with the locking plate is arranged on the fastening element.

13. A valve operating assembly for operating a valve, the valve operating assembly comprising:
a locking plate configured to be screw-connected to the valve;
a hand lever configured to cooperate with the locking plate, the hand lever made of plastic and including:
a lower locking element;
an upper part coupled to the lower locking element;
a fastening element included with the upper part, the fastening element configured for connection to the locking plate;

wherein the locking plate includes a receiving opening configured to receive the fastening element of the hand lever;
wherein one of the receiving opening and the fastening element is oval without a straight edge, and another one of the receiving opening and the fastening element includes a round cross-sectional area;
wherein the receiving opening includes at least one recess or slot; and
wherein the hand lever is connected to the locking plate by way of cooperation between the fastening element and the receiving opening with the fastening element seated within the receiving opening.

14. A valve operating assembly for operating a valve, the valve operating assembly comprising:
a locking plate configured to be screw-connected to the valve;
a hand lever configured to cooperate with the locking plate, the hand lever made of plastic and including:
a lower locking element;
an upper part coupled to the lower locking element;
a fastening element included with the upper part, the fastening element configured for connection to the locking plate;

wherein the locking plate includes a receiving opening configured to receive the fastening element of the hand lever;
wherein the hand lever is connected to the locking plate by way of cooperation between the fastening element and the receiving opening with the fastening element seated within the receiving opening;
wherein one of the receiving opening and the fastening element is oval without a straight edge, and another one of the receiving opening and the fastening element includes a round cross-sectional area; and
wherein the locking plate defines a first stop and a second stop at the receiving opening for limiting rotation of the hand lever, the first stop limits rotation to a completely open state and the second stop limits rotation to a completely closed state.
