Abstract
A method of securely attaching a plate to a malleable metal rod includes forming an integral, generally annular projection on one end of the rod. An opening through the plate is configured to receive the annual projection on the rod. The annual projection is inserted through the opening in the plate and is permanently deformed radially outwardly to overlie and contact the plate at a plurality of spaced locations. The deformations in the annular projection securely attach the plate to the rod.
Claims18
A method of securely attaching a plate to a malleable metal rod, comprising the following steps:
- forming an integral, generally annular projection on one end of said rod;
- forming an opening through said plate configured to receive said annual projection on said rod;
- inserting said annual projection of said rod through said opening in said plate;
- and
- permanently deforming said annular projection on said rod radially outwardly to overlie and contact said plate at a plurality of spaced locations, permanently attaching said plate to said rod.
A rod and plate assembly comprising:
- a rod including a head portion and an integral, generally annular projection having side walls surrounding a recess extending from said head portion;
- a plate defining an opening therethrough configured to receive said side walls of said annular projection, said annular projection extending through said plate opening;
- and
- said annular projection deformed radially outwardly overlying and contacting said plate at a plurality of spaced locations permanently attaching said plate to said rod.
A die member used to secure a plate defining an aperture to a malleable member received by the aperture and being capable of being deformed outwardly fixedly attaching the plate to the member, said die member comprising:
- a head portion;
- a connecting portion integral with said head portion and attachable to a die press;
- and
- wherein said head portion includes a die surface forming a plurality of spaced ribs extending radially outwardly from an axis of said head portion positioned to deform the malleable member radially outwardly to overly and contact the plate.
