BOLT SEAL
A sealing device is provided that includes a bolt having a shaft, a tapered end and a circumferential groove; a lock body having an open end leading into a bore; an overmold substantially surrounding the lock body and including an aperture aligned with the open end of the lock body; a lock ring located in the bore of the lock body; and a washer having a hole aligned with the aperture in the overmold and the opening in the lock body and located between the overmold and the lock ring, the lock ring including a plurality of spokes extending inwardly from an outer ring portion. Some of the spokes can include an inner flange extending generally perpendicular to the spoke, and the inner flanges form a non-continuous inner ring portion.
1 . A sealing device including:
a bolt having a shaft, a tapered end and a circumferential groove;
a lock body having an open end leading into a bore;
an overmold substantially surrounding said lock body and including an aperture aligned with said open end of said lock body;
a lock ring located in said bore of said lock body; and
a washer having a hole aligned with said aperture in said overmold and said opening in said lock body and located between said overmold and said lock ring.
2 . The sealing device as set forth in claim 1 , wherein said lock ring includes a plurality of spokes extending inwardly from an outer ring portion.
3 . The sealing device as set forth in claim 2 , wherein at least some of said spokes include an inner flange extending generally perpendicular to said spokes.
4 . The sealing device as set forth in claim 3 , wherein said inner flanges form a non-continuous inner ring portion.
5 . The sealing device as set forth in claim 1 , wherein said lock body has a generally cylindrical configuration including a closed end opposite said open end.
6 . The sealing device as set forth in claim 5 , wherein said lock body includes a plurality of axially extending ridges projecting from an inner surface of said bore.
7 . The sealing device as set forth in claim 6 , wherein said lock body includes radially extending ridges on an inner surface of said closed end.
8 . The sealing device as set forth in claim 7 , wherein at least some of said axially extending ridges and some of said radially extending ridges intersect at a bottom of said bore.
9 . The sealing device as set forth in claim 7 , wherein said lock body includes a central hub-like ridge from which said radially extending ridges project.
10 . The sealing device as set forth in claim 9 , wherein said hub-like ridge includes a central opening.
11 . The sealing device as set forth in claim 6 , including a counterbore above said axially extending ridges.
12 . The sealing device as set forth in claim 7 , wherein there are twice as many axially extending ridges as radially extending ridges.
13 . The sealing device as set forth in claim 1 , wherein said overmold has a hollow interior and partially closed ends.
14 . The sealing device as set forth in claim 13 , wherein one of said partially enclosed ends of said overmold has a central opening and a plurality of external cavities surrounding said central opening.
15 . The sealing device as set forth in claim 14 , wherein said other end of said overmold has a tapered central hole extending into said central bore.
16 . The sealing device as set forth in claim 1 , wherein said lock body includes scallops in a side wall surrounding said open end.
17 . The sealing device as set forth in claim 11 , wherein said lock body includes an annular lip extending around said counterbore.
18 . The sealing device as set forth in claim 17 , wherein said lock ring is located at the top of said axially extending ridges, and said washer is located over said lock ring in said counterbore.
