Abstract
A length of canted coil spring is disclosed which is suitable for forming a stable, when unsupported, circular axially loadable spring. The length of spring includes a plurality of elliptical coils canted along a coil centerline with the coil centerline following a helical path about a helix centerline. The length of canted coil springs is approximately equal to a distance, or pitch, along the helix centerline necessary for one complete revolution of the helical path thereabout.

A length of canted coil spring suitable for forming a stable, when unsupported, circular axially loadable garter-type spring, said length of canted coil spring comprising:
- a plurality of elliptical coils canted along a coil centerline, said coil centerline following a helical path about a helix centerline when the length of canted coil spring is in an unrestrained, non-circular form, said length of canted coil spring being approximately equal to a pitch along the helix centerline necessary for one complete revolution of the helical path thereabout.
A length of canted coil spring suitable for forming a stable, when unsupported, circular axially loadable garter-type spring, said canted coil spring comprising:
- a plurality of elliptical coils canted along a coil centerline, said coil centerline following a helical path about a helix centerline when the length of canted coil spring is in an unrestrained, non-circular form, and means, defining a length of said canted coil spring, for enabling the length of said canted coil spring to be formed into a circular axial garter-type spring having a major axis of the elliptical coils being approximately in the plane of the circular axially loadable spring.
A length of canted coil spring suitable for forming a stable, when unsupported circular axially loadable garter-type spring, said length of canted coil spring comprising:
- a plurality of elliptical coils canted along a coil centerline, said coil centerline following a helical path about a helix centerline when the length of canted coil spring is in an unrestrained, non-circular form;
- means defining a coil height, measured along a minor axis of each elliptical coils, and a coil wire thickness, for causing the stable circular axially loadable garter-type spring to assume a selected turn angle when the length of canted coil springs is joined to form the circular axially loadable garter-type spring;
- and
- said length of canted coil spring being approximately equal to a pitch along the helix centerline necessary for one complete revolution of the helical path thereabout.
A length of canted coil spring suitable for forming a plurality of stable, when unsupported, circular axially loadable garter-type springs, said length of canted coil spring comprising:
- a plurality of elliptical coils canted along a coil centerline, said coil centerline following a helical path about a helix centerline, when the length of canted coil spring is in an unrestrained, non-circular form, said length of canted coil spring being approximately equal to a multiple of a distance along the helix centerline necessary for one complete revolution of the helical path thereabout.
