Abstract
A casing for use in the manufacture of a resilient joint, the casing having an outer surface and an inner surface, the inner surface defining an internal cavity, wherein the casing has at least one frangible wall section which is adapted to fracture upon the application of a compressive force to the outer surface of the casing such that after such fracture the volume of the internal cavity of the casing is reduced.
Claims24
A method of manufacturing a resilient joint including:
- providing a casing having an outer surface and an inner surface, the inner surface defining an internal cavity, wherein the casing has at least one frangible wall section which is adapted to fracture upon the application of a compressive force to the outer surface of the casing such that after such fracture the volume of the internal cavity of the casing is capable of being reduced;
- locating a connecting member in the internal cavity of the casing;
- introducing an elastomeric material into the internal cavity between the connecting member and inner surface of the casing;
- compressing the casing to cause said at least one frangible wall section to fracture and thereby reduce
- the volume of the internal cavity of the casing in at least that portion filled with elastomeric material.
A method of manufacturing a resilient joint including:
- providing a casing having an outer surface and an inner surface and a first end and a second end, the inner surface defining an internal passage extending from the first end to the second end, three slots equally spaced about the casing in the outer surface and extending from the first end to the second end, each slot having a base and a frangible wall section, each frangible wall section extending from the inner surface of the casing to the base of the respective slot wherein the frangible wall sections are adapted to fracture upon the application of a compressive force to the outer surface of the casing such that after such fracture the casing comprises three segments and the volume of the internal passage is capable of being reduced;
- locating a connecting member in the internal passage of the casing;
- introducing an elastomeric material into the internal passage between the connecting member and the inner surface of the casing;
- and
- compressing the casing to cause the three frangible wall sections to fracture and thereby reduce
- the volume of the internal passage of the casing in at least that portion filled with elastomeric material.
An intermediate article for use in manufacturing a resilient joint including;
- a casing having an inner surface defining an internal space, an outer surface, first and second ends, and at least one slot in the outer surface extending from the first end to the second end, said at least one slot having a base and a frangible wall section extending from the base of the at least one slot to the inner surface;
- a connecting member located at least partially within the internal space of the casing and spaced from the inner surface of the casing, and
- elastomeric material located within the internal space which is located between and bonded to the connecting member and inner surface of the casing, so that the internal space is occupied by the connecting member and the elastomeric material;
- wherein the frangible wall section is breakable upon the application of a compressive force to the casing to reduce the volume of the internal space.
