Cam lever clamp for sanitary fittings

1. A cam-type sanitary clamp for releasably coupling two sanitary fittings, comprising:

an upper clamp ring component having a slotted opening;

a lower clamp ring component attached to the upper clamp ring component at a hinged joint and rotatable thereabout such that the upper clamp ring and lower clamp ring are configurable to surround flanged ends of a sanitary fitting;

a shaft component having a distal end pivotally connected to the lower clamp ring component at a first pivot component, a mid-section which is receivable into the slotted opening in the upper clamp ring component, and a proximal end extending above the slotted opening when the mid-section is inserted within the slotted opening, the shaft component including threading substantially along the length of the shaft component;

a second pivot component in rotatable connection to the threading on the proximal end of the shaft component, the proximal end of the shaft component extending completely through the second pivot component, wherein the second pivot component is adjustable substantially along the length of the shaft component; and

a cam-type lever component pivotally connected to the second pivot component and comprising at least one protrusion configured to be compressed against at least one ledge formed by the slotted opening of the upper clamp ring section when the cam-type lever component is manually rotated about the second pivot component to a closed position to secure the clamp around a sanitary fitting.

2. The clamp of claim 1 , wherein the shaft component is a threaded bolt, and the second pivot component has a threaded cylindrical opening that is threaded onto the shaft component.

3. The clamp of claim 1 , wherein each of the at least one protrusion has at least one rounded surface.

4. The clamp of claim 1 , wherein the second pivot component is substantially cylindrical.

5. The clamp of claim 1 , wherein the clamp further includes a gasket configured to be placed between two sanitary fittings before coupling, thereby creating a fluid tight seal upon the clamp being closed about the sanitary fitting.

6. A clamping means for releasably coupling two sanitary fittings, comprising:

a hinge means for attaching a lower clamp ring component to an upper clamp ring component, thereby allowing the upper clamp ring component and the lower clamp ring component to rotate about the hinge means to surround the flanged ends of sanitary fittings;

a first pivot means for pivotally connecting a distal end of a shaft component to the lower clamp ring component, wherein the shaft component comprises a mid-section which is receivable into a slotted opening in the upper clamp ring component and a proximal end extending above the slotted opening when the mid-section is inserted in the slotted opening;

a connection means for connecting a pivot component to the proximal end of the shaft component; and

a second pivot means for pivotally connecting a cam-type lever means to the pivot component, the shaft component extending completely through the second pivot means, wherein the second pivot means is adjustable substantially along the length of the shaft component; and

a cam-type lever means for selectively moved from an open position to a closed position, the lever means including at least one protrusion configured to be compressed against at least one ledge formed by the slotted opening of the upper clamp ring section when the cam-type lever component is moved to a closed position.

7. The clamping means of claim 6 , wherein the shaft component is a threaded bolt, and the second pivot means has a threaded cylindrical opening and is threaded onto the shaft component.

8. A cam-type sanitary clamp for releasably coupling a tri-clover fitting, comprising:

an upper clamp ring component including a front and back surface thereof;

a lower clamp ring component attached to the upper clamp ring component at a hinged joint, thereby allowing the upper clamp ring component and the lower clamp ring component to rotate about the hinged joint and to surround the flanged ends of a tri-clover fitting;

a shaft component having a distal end pivotally connected to the lower clamp ring component at a first pivot component, a mid-section which is receivable into a slotted opening in the upper clamp ring component, and a proximal end extending above the slotted opening when the mid-section is inserted in the slotted opening, the shaft component including threading substantially along the length of the shaft component;

a cylindrical second pivot component having a threaded cylindrical opening by which the second pivot component is threaded onto the proximal end of the shaft component such that the proximal end of the shaft component extends completely through the cylindrical second pivot component, wherein the cylindrical second pivot component is adjustable substantially along the length of the shaft component;

a set screw configured to set the position of the second pivot component on the shaft component;

a cam-type lever component pivotally connected to the second pivot component and comprising a plurality of protrusions each configured to be compressed against at least one ledge formed by the slotted opening of the upper clamp ring section when the cam-type lever component is manually hinged from an open position to a closed position to hold the clamp about a tri-clover fitting in a fluid tight relationship.
