Abstract: A system, comprising a panel comprising a tetrahedral-octahedral honeycomb lattice, a skin layer formed on a first side of the lattice, having an aperture formed therein configured to receive a fastener, and a fastening assembly comprising a fastener configured to be mounted to the panel when the panel is fixed to an adjacent component, and a hardening material. Corresponding systems and methods also are disclosed.

Abstract: A bike trainer operable by a user for stationary riding when a conventional bicycle is coupled thereto. The bike trainer may be used by removing the rear wheel of the bicycle and selectively coupling the rear dropouts of the bicycle to an axle of the bike trainer. The bike trainer is operative to simulate the “feel” of riding a moving bicycle by providing resistance and inertia similar to that of a bicycle when used normally. To provide these features, the bike trainer includes a fan/flywheel as well as a freewheel mechanism. The bike trainer also includes features that permit simple coupling and decoupling to the bicycle using a “quick release skewer,” which allows users to easily use the bike trainer without required a substantial amount of time. The bike trainer also includes a base configured to support a user of the bike trainer in a fashion such that the user is sturdily supported during use.

Abstract: An exercise device including at least one positionable component configured to be positioned by a user. The exercise device includes a frame to which a collar is mounted. The positionable component includes a member that is slidably received within the collar and may be positioned by sliding the member to a selected position. A locking assembly is coupled to the collar and is operable to lock the member in a selected position within the collar, to release the member from the locked position, and when released, to allow the member to slide within the collar. The locking assembly includes a cam pivotably mounted to the collar and a cam follower assembly selectively biased by the cam against a portion of the member disposed inside the collar. The locking assembly also includes a pair of engagement members disposed inside the collar opposite the cam against which the cam biases the member.
