Abstract

Adjustable and/or dual-suspension boot levers for hardshell boots, having upper parts and lower parts that rotate relative to one another, are disclosed. Adjustable boot levers disclosed herein are adjustable along a continuum or at one of a plurality of preset positions on a lever to provide a forward-lean angle customizable to a user's preferences. Dual-suspension boot levers provide fore-aft dampening and are also customizable by selection of appropriate elastic materials and properties for use in the forward-lean and backward-lean suspension devices. In some embodiments, adjustability and dual-suspension are combined in a boot lever design.

Claims (17)

1. A boot comprising:

a lower part for receiving at least a portion of a user's foot;

an upper part for receiving at least a portion of the user's leg, wherein the upper part and the lower part are connected to one another by at least two pivot points; and

a device that is adjustable between an open position that does not restrict rotation of the upper and lower parts and a closed position that restricts rotation of the upper and lower parts, the device comprising:

a rod in slidable engagement with a housing, each of the rod and the housing connectable to a different one of the upper part and the lower part of the boot, the housing including a first compressible material surrounding the rod and an adjustable plate for applying a compressive force against the first compressible material; and

a second compressible material surrounding the rod,

wherein axial movement of the housing relative to the rod exerts opposite forces on the first and second compressive materials.

2. The boot of claim 1 , wherein the second compressible material is disposed outside the housing.

3. The boot of claim 1 , wherein the second compressible material is disposed inside the housing and is separated from the first compressible material by the plate.

4. The boot of claim 1 , wherein the rod is threaded.

5. The boot of claim 1 , further comprising a connector head that is translatable along a length of the rod.

6. The boot of claim 5 , wherein the connector head is configured to mate with an interface on the lower part of the boot.

7. The boot of claim 1 , wherein the first compressible material and/or the second compressible material is/are selected from the group consisting of a spring, a bumper of elastic material, an air shock, a hydraulic shock, or combinations thereof.

8. The boot of claim 1 , wherein the housing comprises one or more openings for receiving a cable.

9. The boot of claim 1 , further comprising a bracket hingedly mounted to the housing.

10. The boot of claim 9 , wherein the bracket is mounted on the upper part of the boot.

11. The boot of claim 9 , wherein the bracket comprises a slot for receiving an end of the connector rod.
