Abstract: An adjustable helmet having first and second shells and a single actuator comprising at least one tooth, the single actuator being moveable between: a first locked position, wherein the at least one tooth retains the first and second shells and the first and second shells define a first hollow space; a released position, wherein the at least one tooth no longer retains the first and second shells such that one of the first and second shells is moveable relative to the other of the first and second shells; and a second locked position, wherein the at least one tooth retains the first and second shells and the first and second shells define a second hollow space, the second hollow space being different than the first hollow space.

Abstract: A length-adjustable snowshoe includes a frame and a carrier fixed to the frame. A connecting member mounted to the frame includes two receiving holes. A pivotal portion is formed on a top side of the connecting member. A compartment extends from the pivotal portion through one of the receiving holes. An extension member includes legs slideably received in the receiving holes and is slideable between first and second positions. A sliding member is mounted on the extension member to move therewith. A positioning member is received in the compartment and pivotable between a stop position and a releasing position. The positioning member in the stop position retains the extension member in any location including and intermediate the first and second positions. The extension member can slide between the first and second positions when the positioning member is in the releasing position.

Abstract: A shoe with a height-adjustable heel including a heel having a first heel member fixedly attached to the sole and a second heel member telescopically disposed within the first heel member which is operated by a hydraulic pump disposed in the first heel member and a pump lever, pivotally disposed on a rear wall of the first heel member, by which the hydraulic pump is activated to extend and retract the second heel member to respectively lengthen and shorten the heel and which also includes a twist-lock valve mechanism in a heel tip that controls the passage of air into the hydraulic pump.
