Filed:

Feb 27, 2019

Appl. No.:

16/287869

Inventors:

- Golden CO, US
Carl Nelson - Golden CO, US

International Classification:

F16F 3/12
F16F 1/04
A43B 21/30

Abstract:

A shock absorbing device having at least one nautilus spring disposed between two members is described. When the members move toward each other, the one or more nautilus coil springs are canted and compressed. The shock absorbing device takes advantage of the unique force-displacement curve of canted springs and reduces bounce back.

F16F 1/04

Abstract:

A latching connector having a pin, a housing, and a canted coil spring is disclosed. The housing has an opening that slidably receives the pin. The housing and the pin each have a groove that is sized and dimensioned to receive a portion of the canted coil spring. The pin groove and housing groove have a curved surface with a radius that is equal to or larger than the major axis of the canted coil spring. The canted coil spring has an outer diameter that is equal to or larger than the diameter of the housing groove. Together, the pin, housing, and canted coil spring provide a latching connector with a reliable and consistent connect force and disconnect force. The latching connector provides improved electrical conductivity from the pin to the housing by providing multiple contact points with the canted coil spring.
