Clamping device
A clamp assembly includes a first clamp half-piece and a second clamp half-piece. In one example, the clamp half-pieces are identically shaped. In one example, each of the clamp half-pieces has at least one integral pin and at least one aperture. The first and second clamp half-pieces are pivotally connected to each other via a first snap-fit interface in which the integral pin of the first clamp half-piece snap-fits into the at least one aperture of the second clamp half-piece. The clamp assembly can also include a link arm connected to the first clamp half-piece via a second snap-fit interface. A lever arm can also be included that is pivotally connected to the link arm via a third snap-fit interface. The clamp assembly does not require separate link pins or other parts and only includes four components: the clamp half-pieces, the link arm, and the lever arm.
1. A clamp assembly comprising:
a) a first clamp half-piece having a generally semi-circular body that extends along a curved path between first and second ends; and
b) a second clamp half-piece having a generally semi-circular body that extends along a curved path between first and second ends;
c) wherein the first clamp half-piece is pivotally connected to the second clamp half-piece with a pin structure received into a tapered slot structure extending into an aperture, wherein the pin structure is received through the tapered slot structure and into the aperture such that the pin structure and aperture are coaxially aligned along a common axis.
2. The clamp assembly of claim 1 , wherein the pin structure includes at least one pin integrally formed on each of the first and second clamp half-pieces and the aperture includes at least one aperture integrally formed on each of the first and second clamp half-pieces.
3. The clamp assembly of claim 1 , further comprising:
a) a link arm pivotally connected to the first clamp half-piece; and
b) a lever arm pivotally connected to the link arm, the lever arm being configured to retain the first and second clamp half-pieces in a closed position.
4. The clamp assembly of claim 3 , wherein the first and second clamp half-pieces include outer surfaces that curve in convex curvatures along major dimensions and also curve in convex curvatures along minor dimensions, and wherein the lever arm has a bottom surface that includes concave curvatures to cooperate with the convex curvatures of the first and second clamp half-pieces.
5. The clamp assembly of claim 1 , wherein the first and second clamp half-pieces are identically shaped.
6. A clamp assembly comprising:
a) a first clamp half-piece having a generally semi-circular body that extends along a curved path between first and second ends; and
b) a second clamp half-piece having a generally semi-circular body that extends along a curved path between first and second ends, the second clamp half-piece being pivotally connected to the first clamp half-piece via a first snap-fit connection, wherein the first snap-fit connection includes at least one pin integrally formed on each of the first and second clamp half-pieces and at least one aperture integrally formed on each of the first and second clamp half-pieces.
7. The clamp assembly of claim 6 , further including:
a) a closure assembly joining the second ends of the first and second clamp half-pieces together, the closure assembly being mounted to one of the first and second clamp half-pieces via a second snap-fit connection, wherein each of the first and second clamp half-pieces are configured to provide the second snap-fit connection such that the closure assembly can be selectively mounted on either of the first and second clamp half-pieces.
8. The clamp assembly of claim 6 , further comprising:
a) a link arm pivotally connected to the first clamp half-piece; and
b) a lever arm pivotally connected to the link arm, the lever arm being configured to retain the first and second clamp half-pieces in a closed position.
9. The clamp assembly of claim 8 , wherein the first and second clamp half-pieces include outer surfaces that curve in convex curvatures along major dimensions and also curve in convex curvatures along minor dimensions, and wherein the lever arm has a bottom surface that includes concave curvatures to cooperate with the convex curvatures of the first and second clamp half-pieces.
10. A clamp assembly comprising:
a) a first clamp half-piece having a generally semi-circular body that extends along a curved path between first and second ends; and
b) a second clamp half-piece having a generally semi-circular body that extends along a curved path between first and second ends, the second clamp half-piece being connected to the first clamp half-piece;
c) wherein the first and second clamp half-pieces each include an outer surface having a curved transverse cross-sectional shape.
11. The clamp assembly of claim 10 , wherein the first and second clamp half-pieces are connected together with a snap-fit type connection.
12. The clamp assembly of claim 10 , further comprising:
a) a closure assembly joining the second ends of the first and second clamp half-pieces together.
13. The clamp assembly of claim 12 , wherein the closure assembly is rotatably mounted to one of the first and second clamp half-pieces via a snap-fit type connection.
14. The clamp assembly of claim 12 , wherein the closure assembly includes a lever arm having a bottom surface that includes concave curvatures to cooperate with convex curvatures of the first and second clamp half-pieces.
15. The clamp assembly of claim 11 , wherein the snap-fit type connection includes a pin structure and a tapered slot structure extending into an aperture, wherein the pin structure is received through the tapered slot structure and into the aperture such that the pin structure and aperture are coaxially aligned along a common axis.
16. The clamp assembly of claim 11 , wherein the snap-fit type connection includes at least one pin integrally formed on each of the first and second clamp half-pieces and at least one aperture integrally formed on each of the first and second clamp half-pieces.
17. The clamp assembly of claim 12 , wherein the first and second clamp half-pieces and the closure assembly are formed from the same material.
