Abstract

A joint assembly includes a clamp member and a spacer plate. The clamp member includes a first jaw surface and a second jaw surface that define a gap therebetween. The spacer plate is connected to the clamp member such that the spacer plate is disposed within the gap between the first jaw surface and the second jaw surface. The spacer plate includes a body and a seal member. The body includes a perimeter. The seal member is connected to the body such that it is disposed adjacent the perimeter of the body. The seal member extends over a segment of the perimeter of the body. The seal member is in sealing engagement with the first jaw surface and the second jaw surface.

First claim

What is claimed is:

1. A spacer plate comprising:
a body, the body including a perimeter and a spline, the spline projecting from the perimeter of the body, the body being made from a body material;
a seal member, the seal member including a pair of terminal portions, the seal member connected to the body such that the spline is embedded within the seal member, the seal member disposed adjacent the perimeter of the body, the seal member partially extending over a segment of the perimeter of the body such that the pair of terminal portions are in non-contacting relationship with each other, the seal member being made from a seal member material, the body material being harder than the seal member material;
wherein the perimeter of the body includes a first end, a second end, a first sidewall and a second sidewall the first end and the second end in spaced longitudinal relationship to each other along a longitudinal axis defined by the body, the first sidewall and the second sidewall in spaced lateral relationship to each other along a transverse axis perpendicular to the longitudinal axis, the first sidewall and the second sidewall both extending longitudinally between the first end and the second end;
wherein the spline projects from the first end, the second end, and one of the first sidewall and the second sidewall; and
wherein the segment of the perimeter over which the seal member extends includes the first end, the second end, and only said one of the first sidewall and the second sidewall, such that the other of the first sidewall and the second sidewall is free of any seal member material.

2. The spacer plate according to claim 1 , wherein the seal member includes an exterior seal member surface having a first sealing face surface and a second sealing face surface, the exterior seal member surface defining a recessed cutout extending between the first sealing face surface and the second sealing face surface.

3. The spacer plate according to claim 2 , wherein the seal member projects outwardly from the perimeter such that the recessed cutout is outwardly displaced from the perimeter of the body.

4. The spacer plate according to claim 1 , wherein the seal member includes an exterior seal member surface having a first sealing face surface and a second sealing face surface, the exterior seal member surface defining a recessed cutout extending between the first sealing face surface and the second sealing face surface of the exterior seal member surface, the recessed cutout disposed along one of the first end and the second end of the perimeter, the seal member projecting outwardly from the perimeter such that the recessed cutout is outwardly displaced from said one of the first end and the second end of the perimeter of the body.

5. The spacer plate according to claim 4 , wherein the recessed cutout comprises a first recessed cutout, and wherein the exterior seal member surface defines a second recessed cutout extending between the first sealing face surface and the second sealing face surface, the first recessed cutout and the second recessed cutout disposed respectively along the first end and the second end of the perimeter, the seal member projecting outwardly from the perimeter such that the first recessed cutout is outwardly displaced from the first end of the perimeter of the body and the second recessed cutout is outwardly displaced from the second end of the perimeter of the body, and wherein the segment of the perimeter over which the seal member extends is larger than the spline such that the pair of terminal portions of the seal member is respectively connected to the first end and the second end of the perimeter of the body without the spline being interposed therebetween.

6. The spacer plate according to claim 1 , wherein the body includes a first face and a second face, the second face in opposing relationship to the first face, and wherein the seal member includes a first bead and a second bead, the first bead and the second bead respectively projecting from the first face and the second face of the body.

7. The spacer plate according to claim 6 , wherein the first face and the second face of the body are substantially planar, the first bead and the second bead respectively projecting from the first face and the second face of the body along a normal axis, the normal axis being perpendicular to the first face and the second face.

8. The spacer plate according to claim 7 , wherein the first bead has a triangular cross-sectional shape, the first bead including a pair of converging bevel surfaces.

9. The spacer plate according to claim 8 , wherein the pair of converging bevel surfaces defines, respectively, a first bevel angle and a second bevel angle with respect to the first face.

10. The spacer plate according to claim 9 , wherein the first bevel angle and the second bevel angle are substantially equal to each other.

11. The spacer plate according to claim 9 , wherein the first bevel angle and the second bevel angle are both in a range between twenty-five degrees and sixty-five degrees.

12. The spacer plate according to claim 11 , wherein the first bevel angle and the second bevel angle are substantially equal to each other.

13. A joint assembly comprising:
a clamp member, the clamp member including a first jaw surface and a second jaw surface, the first jaw surface and the second jaw surface defining a gap therebetween;
a spacer plate, the spacer plate connected to the clamp member such that the spacer plate is disposed within the gap between the first jaw surface and the second jaw surface, the spacer plate including:
a body, the body including a perimeter and a spline, the spline projecting from the perimeter of the body, the body being made from a body material, and
a seal member, the seal member including a pair of terminal portions, the seal member connected to the body such that the spline is embedded within the seal member, the seal member disposed adjacent the perimeter of the body, the seal member extending over a segment of the perimeter of the body such that the pair of terminal portions are in non-contacting relationship with each other, the seal member being made from a seal member material, the body material being harder than the seal member material, and the seal member in sealing engagement with the first jaw surface and the second jaw surface,
wherein the perimeter of the body includes a first end, a second end, a first sidewall and a second sidewall the first end and the second end in spaced longitudinal relationship to each other along a longitudinal axis defined by the body, the first sidewall and the second sidewall in spaced lateral relationship to each other along a transverse axis perpendicular to the longitudinal axis, the first sidewall and the second sidewall both extending longitudinally between the first end and the second end,
wherein the spline projects from the first end, the second end, and one of the first sidewall and the second sidewall, and
wherein the segment of the perimeter over which the seal member extends includes the first end, the second end, and only said one of the first sidewall and the second sidewall, such that the other of the first sidewall and the second sidewall is free of any seal member material.

14. The joint assembly according to claim 13 , wherein the clamp member includes an inner cylindrical wall defining a bore extending therethrough, the gap in communication with the bore and extending radially outwardly therefrom, the joint assembly further comprising:
a pin, the pin disposed within the bore of the clamp member and in retentive engagement with the inner cylin
