A flat board as a base plate of a binding for splitboards with holders for the bindings' fixation on skis that are joined together to form a snowboard that has a circular slit (or opening) formed in a central part of the board. The circular slit is equipped with a perimeter recess for removable fixation of a contact ring which is, on its inner perimeter, equipped with two pairs of opposed dents (or indentations) that are designed for connection with a holder. The contact ring is also modified between the dents (or indentations) for insertion of end pins of a locking eccentric. The locking eccentric is formed by an axial shaft with end pins protruding from end hubs formed at both ends of the axial shaft.

A splitboard boot binding system with single multi-angle climbing wire. The pivotable climbing wire is configured for use with any compatible ski tour interface, and folds away under the boot binding baseplate when the bindings are transferred to a ride mode interface. In ski tour mode, the baseplate pivots on a toe axis and is supported by the climbing wire when the heel is raised. Advantageously, the climbing wire is very lightweight and seats interchangeably in a plurality of detent positions on a compatible heelblock. There are no interferences with conjoint use of a slide-in crampon seated between the heelblock and the toe pivot or with use in systems having a heel locker. Surprisingly, in some combinations the climbing wire may also be used to retain the slider track in ride mode. The combinations and sub-combinations require no tools for adjustment or operation and operate cooperatively.

A detachable modular electric skateboard which comprises a board body, wheel frames arranged at the bottom of the board body and provided with wheels driven by external force to travel together with the board body and the wheel frames, a traveling suspension part detachably installed at the end of the board body, and a power supply control part arranged at the bottom of the board body and provided with a detachably-installed battery assembly, and further discloses a remote control device for controlling the electric skateboard. Through the detachable traveling suspension part and the power supply control part, the advantages of existing electric skateboards and ordinary skateboards are integrated, a user can achieve the function switching according to requirements, and the detachable modular electric skateboard can replace daily vehicles driven by manpower and perfectly shows the recreational significance of ordinary skateboards serving as sports equipment.

Fixation of a binding board to skis demountable connected into a form of a splitboard uses a sliding demountable setting of bearing pins in eyes formed on adjacent areas of the board and a clamp fixed to the skis. The essence of the invention is a fixation of the lateral parts of the eyes by stoppers which partially overreach into the cross sections of the eyes. The diameter of the bearing pins basically corresponds with the diameters of the eyes. The bearing pins are equipped with circular recesses for engaging of the stoppers and also with end parts formed as from above one-sidedly reduced conical tips.

A wheeled system for engagement with a surfboard is provided. Wheeled trucks are configured for removable engagement with a lower surface of a surfboard using mounting plates or recessed connections. The removable engagement of the trucks allow a rider to ride on support surfaces such as the sidewalk, and to remove the trucks to employ the surfboard in the water. The removable trucks may be retrofitted to existing surfboards with an elastic or mechanical engagement, or may be provided in combination with a surfboard.

A binding system includes a base portion shaped to receive a boot. The base portion has first and second opposite facing surfaces. The binding system also includes a first interface having first and second surfaces. The first interface includes two separable interface portions, with each of the two interface portions having first and second opposite facing surfaces and including at least one coupling element disposed over at least the second surface of the interface portion. The at least one coupling element includes a body segment proximate to the second surface of the interface portion and a blocking head segment distal to the second surface of the interface portion. The body segment has a first width with respect to a longitudinal axis of the body segment and the blocking head section having a second, greater width than the first width.

The present invention contemplates a binding system for a snowboards and the like. The system includes a soft-soled boot having a hardened exterior shell consisting of a toe portion and a heel portion, which are linked by at least one sidewall portion. The toe and heel portions include two toe and two heel pegs respectively. The boot includes an instep portion having instep cables for adjusting the boot to the wearer and the cables are adjusted by grommets and tightened in position by at least one resting bar. The binding has a base plate for connecting to the snowboard. The base plate further supports a pair of toe hooks adapted to engage the toe pegs and a pair of heel peg levers adapted to releasably engage the heel pegs of the boot. A grappling hook and ratchet mechanism grabs the resting bar on the boot.

A mechanism is described for facilitating a smart hybrid selfie cane. An apparatus of embodiments, as described herein, includes a hybrid selfie cane to serve as at least one of a selfie stick and a cane, wherein the hybrid selfie cane includes the selfie stick coupled to the cane.

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.
