Abstract

A suction-cup device has a cup-shaped support body having a cup opening and a hole. A suction diaphragm is positioned in the cup opening of the cup-shaped support body. A rod extends through the hole and is connected to the suction diaphragm. A clamp has first and second arms pivotally connected together at an articulation pin, the first and second arms each having a clamping jaw at one end and an actuating section at another end. The clamping jaws are biased toward each other. The clamp has a clamping member pivotally connected to the rod by a pivot pin which extends in a direction transverse to a direction of the articulation pin. The clamping member operatively contacts the cup-shaped support body and moves the rod and actuates the suction diaphragm when the clamping member is pivoted to a suction position. The clamping member moves the rod and releases the suction diaphragm when the clamping member is pivoted to a release suction position.

Claims

1. A suction-cup device, comprising:

a cup-shaped support body having a cup opening and a hole;

a suction diaphragm positioned in the cup opening;

a rod extending through the hole and connected to the suction diaphragm; and

a clamp having first and second arms pivotally connected together at an articulation pin, the first and second arms each having a clamping jaw at one end and an actuating section at another end, the clamping jaws being biased toward each other, the clamp having a clamping member pivotally connected to the rod by a pivot pin which extends in a direction transverse to a direction of the articulation pin, the clamping member having a suction position and a release suction position pivoted about the pivot pin.

2. The suction-cup device of claim 1, wherein the clamping member operatively contacts the cup-shaped support body, the clamping member moving the rod and actuating the suction diaphragm when the clamping member is pivoted to the suction position, the clamping member moving the rod and releasing the suction diaphragm when the clamping member is pivoted to the release suction position.

3. The suction-cup device of claim 2, wherein the clamping member is positioned between a vertex of the clamp at the clamping jaws and the articulation pin.

4. The suction-cup device of claim 2, wherein a reference plane defined by the clamping jaws when abutting each other and the articulation pin is substantially parallel to a fastening plane defined by a peripheral edge of the cup-shaped support body.

5. The suction-cup device of claim 2, wherein the clamping member has a fork-shaped mounting portion, the rod pivotally mounted to the fork-shaped mounting portion such that the clamping member can be placed in the release suction position in opposite pivoting positions.

6. The suction-cup device of claim 1, wherein the clamp has a spring biasing the clamping jaws toward each other, the actuating sections of the first and second arms being movable toward each other against a biasing force of the spring to spread the clamping jaws apart from each other.

7. The suction-cup device of claim 1, wherein the clamping member is an extension of the clamp and has a clamping surface and a side surface positioned substantially perpendicularly or trapezoidally in relation to each other.

8. The suction-cup device of claim 7, wherein the extension has a pair of side surfaces positioned trapezoidally in relation to the clamping surface.

9. The suction-cup device of claim 7, wherein the clamping member is positioned between a vertex of the clamp at the clamping jaws and the articulation pin.

10. The suction-cup device of claim 7, wherein a reference plane defined by the clamping jaws when abutting each other and the articulation pin is substantially parallel to a fastening plane defined by a peripheral edge of the cup-shaped support body.

11. The suction-cup device of claim 7, wherein the clamping member has a fork-shaped mounting portion, the rod pivotally mounted to the fork-shaped mounting portion such that the clamping member can be placed in the release suction position in opposite pivoting positions.

12. The suction-cup device of claim 1, wherein the clamping member is positioned between a vertex of the clamp at the clamping jaws and the articulation pin.

13. The suction-cup device of claim 12, wherein a reference plane defined by the clamping jaws when abutting each other and the articulation pin is substantially parallel to a fastening plane defined by a peripheral edge of the cup-shaped support body.

14. The suction-cup device of claim 12, wherein the clamping member has a fork-shaped mounting portion, the rod pivotally mounted to the fork-shaped mounting portion such that the clamping member can be placed in the release suction position in opposite pivoting positions.

15. The suction-cup device of claim 1, wherein a reference plane defined by the clamping jaws when abutting each other and the articulation pin is substantially parallel to a fastening plane defined by a peripheral edge of the cup-shaped support body.

16. The suction-cup device of claim 15, wherein the clamping member has a fork-shaped mounting portion, the rod pivotally mounted to the fork-shaped mounting portion such that the clamping member can be placed in the release suction position in opposite pivoting positions.

17. The suction-cup device of claim 1, wherein the clamping member has a fork-shaped mounting portion, the rod pivotally mounted to the fork-shaped mounting portion such that the clamping member can be placed in the release suction position in opposite pivoting positions.
