A portable energy-saving and environment-friendly electric vehicle is light in weight, small in volume, convenient in electricity charging, and disassemble to be collected into a backpack for portability. The backpack is further furnished with a crank-handle generator to fulfill manpower electricity generation and working out simultaneously. This energy-saving and environment-friendly electric vehicle is mainly consisted of two adjustable skateboards and a support rod for adjusting speed and connecting a battery set. The battery set can be conveniently replaced roadside or domestically. In a situation of power out, manpower can be used to charge the battery set. Thus, the situation of power out to shut down the electric vehicle can be met. In addition, the battery set associated with the generator is reliable for charging mobile phones and computers.

The present invention concerns the field of garments, namely the shoes sector, especially relating to children, although it is likewise applicable to young people and adults. The object of the present invention is an outer sole (1), on which are inserted two structures, a first one enabling one user to slide when he is contacting the ground, moving as if he were on skates, and a second one enabling the user to move in a conventional way. The first structure, which enables a movement in a rolling mode, consists in a frame (2) containing a wheel (3) and, on one end, presents a front locking member (4) and, on another end, a locking member (5) for disengagement of the frame (2) by pressing downwards.

A system for securing a snowboard binding to a snowboard may be an intermediary between the snowboard binding and the snowboard. In some embodiments, the system includes an expandable snowshoe attachment device. The system for securing a snowboard binding to a snowboard may include an upper piece and one or more lower pieces. The upper piece may be configured to attach to a lower surface of a baseplate of a snowboard binding. The one or more lower pieces may be rails. The rails may be fastened to a snowboard. The upper piece may include one or more extensions. The one or more extensions may deploy to increase a bottom surface area of the upper piece. Increasing the bottom surface area of the upper piece may increase the flotation of the upper piece on surfaces such as snow.

Systems and methods for fixing a binding board to skis that are removably connected together to form of a splitboard are described herein. In some cases, the described systems use a sliding and removable setting of bearing pins in eyes that are formed on adjacent areas of the board and a clamp that is fixed to the skis. The essence of the invention is a fixation of lateral parts of the eyes by stoppers which partially overreach into cross sections of the eyes. A diameter of the bearing pins basically corresponds with a diameter of the eyes. The bearing pins are equipped with circular recesses for engaging with the stoppers and also with end parts that each have a truncated conical tip.

A system and method for providing a ski-snowboard device capable of skinning in an uphill ski mode and skiing in a downhill snowboard mode. The system may include two skis with inner and outer edges having substantially convex side cuts, and an insert that fits into the space between the inner edge side cuts of each of the two skis. The convex side cuts of the inner edges of the skis may have a groove formed in each, and a mating tongue on each side of the insert can fit into the grooves in a downhill snowboard mode. The tongue-and-groove connection may improve the torsional stiffness of the board, and the convex side cuts may allow a user to better grip when skiing and eliminate the step of switching the skis when used as sides of the snowboard.

A modular skateboard assembly for facilitating a user to employ a pair of skateboards in the convention of a skateboard or roller skates includes a pair of skateboards which each includes a pair of rollers that roll along a support surface. Each of the skateboards is attachable together such that the pair of skateboards extends along a common axis thereby facilitating the pair of skateboards to be employed in the common convention of skateboards. Furthermore, each of the skateboards is detachable from each other thereby facilitating the pair of skateboards to be employed in the common convention of roller skates. Each of the skateboards includes a pair of foot restraints to restrain a respective one of a user's feet.

A portable energy-saving and environment-friendly electric vehicle is light in weight, small in volume, convenient in electricity charging, and can be disassembled for portability in a backpack. The backpack is further furnished with a crank-handle generator to enable manpower electricity generation and working out simultaneously. This energy-saving and environment-friendly electric vehicle is mainly comprised of two adjustable skateboards and a support rod for adjusting speed and connecting a battery set. The battery set can be conveniently replaced roadside or at other locations. In a situation of power loss, manpower can be used to charge the battery set. Thus, the situation of power loss fully disabling the electric vehicle can be met. In addition, the battery set associated with the generator is reliable for charging mobile phones and computers.

Detachable propelling apparatus to be fastened to a snowboard in order to propel it uphill. Said apparatus is equipped with foldable or removable tracks, being these tracks powered by either an engine, or a motor or a turbine. The apparatus is integral with an apt adjustable attachment plate, that is directly fastenable to the feet rests (boots attachments) holes of the snowboard. The invention is completed by a rucksack for transporting tracks and batteries, with an opportune frame for protecting the back of the wearer in case of fall and a remote control, in case equipped with movement sensors. The invention is a solution for the technical problem of powering a snowboard limiting the impact of such fixture on the snowboard itself.

The splitboard fastening system is for use with a splitboard having first and second splitboard skis. The splitboard fastening system includes an adjustable crossbar attachment, configured to be coupled to the first splitboard ski, and including a crossbar having an engagement interface that is adjustable relative to a center seam of the splitboard. A rotatable lever attachment is configured to be coupled to the second splitboard ski, and includes a post, defining an axis of rotation, and coupled to a lever. Wherein, in a locked configuration, the post exerts a lateral force against the engagement interface of the crossbar based upon rotation of the lever.
