Abstract
The present invention pertains to a spring or alternative elastic, resilient, compressible media cassette for a touring-style ski binding, such as used in alpine touring or telemark skiing. The touring ski binding slip differential cassette provides the skier with variety of tuning options to manually adjust binding size, stiffness, and range of motion. Manual adjustment of binding size, stiffness, and range of motion enhances the touring ski binding ease of use, adjustability, and overall capabilities, further progressing the touring ski binding. In addition, the slip differential cassette provides the touring skier with cassette presets that match each skier to a predetermined binding size, stiffness, and range of motion based on skier weight and ability.
Claims25
A slip differential cassette, configured to connect to a free-heel ski binding, comprising:
- a cassette cylinder, having a first end and a second end;
- a piston, including a piston head, which rests at the first end of the cassette cylinder, and a piston shaft;
- at least one spring device received within a cassette chamber, between the piston head and the second end;
- and
- a slip differential bolt having a central conduit, through which the piston shaft passes, wherein the slip differential bolt is equipped with threading configured to thread into the second end of the cassette cylinder, to adjust a compression applied to the at least one spring device, enabling a modifiable binding stiffness and responsiveness, and to modify a binding range of motion and an amount of binding free-heel extension by adjusting a distance that the piston head is capable of traveling towards the second end.
A slip differential cassette configured to connect to a free-heel ski binding, comprising:
- a cassette cylinder;
- a piston, having a piston head and a piston shaft;
- at least one spring device received within the cassette cylinder and configured to be compressed by the piston head;
- a slip differential bolt having a central conduit, through which the piston shaft passes, wherein the slip differential bolt is equipped with threading configured to thread into an end of the cassette cylinder, wherein the slip differential bolt is configured to enable an adaptable binding stiffness and responsiveness and to modify a range of binding motion and an amount of binding free-heel extension by adjusting a length of the spring, a distance that the piston head is capable of traveling during spring compression, and the total amount of compression that the piston head can apply to the at least one spring device.
A slip differential cassette configured to connect to a free-heel ski binding, comprising:
- a cassette cylinder;
- a piston, having a piston head and a piston shaft;
- at least one spring device received within the cassette cylinder and configured to be compressed by the piston head;
- a cassette cap equipped with threading configured to thread onto one end of the cassette cylinder, wherein the cassette cap is configured to enable an adaptable binding stiffness and responsiveness and to modify a range of binding motion and an amount of binding free-heel extension by adjusting a length of the spring, a distance that the piston head is capable of traveling during spring compression, and the total amount of compression that the piston head can apply to the at least one spring device.
