A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

An adjustable ski binding adapter apparatus that adapt a snowboard boot for use with alpine ski bindings. The ski binding adapter apparatus includes a back support pivotally coupled to a sole plate, where the back support pivots to aid in stepping into the ski binding adapter apparatus. The sole plate is adjustable for length. Adjustable strap assemblies are coupled to the sole plate and the back support and snugly encircle and restrain the boot in the ski binding adapter apparatus. The back support and the sole plate are configured to conform to ski boot standards and attach to a conventional ski binding.

An apparatus that secures a skateboard platform to a snow ski with a base that has a sliding member and stationary member. An adjustment mechanism urges the sliding member to move toward or away from the stationary member. A stabilizer is movable toward and way from the sliding member via a guide path in the base. The stabilizer has two components that move one inside the other to lengthen or shorten a distance between their respective ends. The sliding member has a protruding portion that fits into a front snow ski binding. The stationary member snaps into the rear snow ski binding. The front binding is sandwiched between the stabilizer and the sliding member.

The invention relates to an device for attaching a ski to a bicycle trailer, which device is characterised by: a ski-side connector piece, in the form of a ski boot sole, comprising a front and a rear insertion part for insertion into the front and rear jaws of a standard safety binding for alpine skis; means for attaching the device to the bicycle trailer; and a leg section that fixedly connects the connection piece to the attachment means.

A functional shoe includes a sole, a functional part to provide a specific function to the functional shoe, a fixing part provided to fix the functional part; and a coupling part provided to be coupled to the fixing part, and directly or indirectly coupled to the sole, at an opposite side to a side coupled to the fixing part. The fixing part includes a fixing body provided to be coupled to the functional part, and a leg member formed to extend from the fixing body in a reference direction which is a direction facing the sole from the fixing body. The coupling part includes an insertion slot provided inside the coupling part to be open in a direction opposite to the reference direction such that the leg member is inserted into the insertion slot.

A ski seat assembly is provided that includes a support structure, a seat coupled to the support structure, and an adjustable binding insert mechanism coupled to the support structure. The adjustable binding insert mechanism including a toe piece, a heel piece, and an adjustable connector connecting the toe piece to the heel piece, wherein the adjustable connector is adjustable to adjust a length of the adjustable binding insert mechanism to fit into a binding on a ski.

A ski seat assembly is provided that includes a support structure, a seat coupled to the support structure, and an adjustable binding insert mechanism coupled to the support structure. The adjustable binding insert mechanism including a toe piece, a heel piece, and an adjustable connector connecting the toe piece to the heel piece, wherein the adjustable connector is adjustable to adjust a length of the adjustable binding insert mechanism to fit into a binding on a ski.

A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

A locomotion apparatus that has a base that secures a skateboard platform to a snow ski as a combination. The base is secured into position by bindings of a ski. A brake mechanism is provided that has a brake seat, a lever arm and a spring arm that cooperate with each other to enable the brake mechanism to move between a deployed brake position, at which the combination brakes to prevent its locomotion, and a non-deployed brake position, at which the locomotion is enabled.

A functional shoe includes a sole, a functional part to provide a specific function to the functional shoe, a fixing part provided to fix the functional part; and a coupling part provided to be coupled to the fixing part, and directly or indirectly coupled to the sole, at an opposite side to a side coupled to the fixing part. The fixing part includes a fixing body provided to be coupled to the functional part, and a leg member formed to extend from the fixing body in a reference direction which is a direction facing the sole from the fixing body. The coupling part includes an insertion slot provided inside the coupling part to be open in a direction opposite to the reference direction such that the leg member is inserted into the insertion slot.
