Abstract
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.
Claims19
A free-heel ski binding, comprising:
- a doubly open-ended cylinder, having a first end and a second end;
- a piston, having a head and a shaft;
- at least one spring device received within the cylinder and configured to be compressed by the piston head;
- a cylinder nut or cap configured to attach to a portion of the first end of the doubly open-ended 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;
- wherein the portion of the first end of the doubly open-ended cylinder comprises either female threading along a portion of the interior of the cylinder configured to attach to a portion of male threading on a cassette nut or male threading along a portion of the exterior of the cylinder configured to attach to a portion of female threading on a cassette cap.
A free-heel ski binding, comprising:
- a doubly open-ended cylinder;
- a piston, having a head portion and a shaft portion;
- at least one spring device received within the cylinder and configured to be compressed by the piston head;
- a cylinder nut or cap configured to attach to a portion of an end of the doubly open-ended 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;
- wherein the portion of the end of the doubly open-ended cylinder comprises either female threading along a portion of the interior of the cylinder configured to attach to a portion of male threading on a cassette nut or male threading along a portion of the exterior of the cylinder configured to attach to a portion of female threading on a cassette cap.
A free-heel ski binding, comprising:
- a doubly open-ended cassette cylinder;
- a piston, having a head and a shaft;
- at least one spring device received within the cassette cylinder and configured to be compressed by the piston head;
- a cassette cylinder nut or cap configured to attach to a portion of an end of the doubly open-ended cassette cylinder, to adjust a compression applied to the at least one spring device, to enable an adaptable binding stiffness and responsiveness, and to modify a range of motion of the binding, an amount of binding free-heel extension by adjusting a starting length of the spring, a distance that the piston head is capable of traveling during spring compression, and a total amount of compression that the piston head can apply to the at least one spring device;
- wherein the portion of the end of the doubly open-ended cylinder comprises either female threading along a portion of the interior of the cylinder configured to attach to a portion of male threading on a cassette nut or male threading along a portion of the exterior of the cylinder configured to attach to a portion of female threading on a cassette cap.
