A foam product includes a foam core, a soft skin covering the foam core, and a base structure on which the foam core is disposed. The foam core of expanded beads has an outer surface on which some outermost beads of the expanded beads are exposed and bulging outward with different heights to form a bubbly texture. The foam skin has an inner surface attached to the outer surface of the foam core, and has at its inner surface a plurality of concave cavities each matedly surrounding a respective one of the bulging, outermost beads on the outer surface of the foam core.

The present disclosure relates to a binding equipment for binding a hard-shell boot comprising a profiled bottom surface to a ski, the ski comprising a bottom surface to be directed towards a gliding element and a top surface to be directed towards the boot, wherein the binding equipment is configured to adapt the top surface of the ski to the profiled bottom surface of the boot.

A trailer system for transporting multiple adult passengers and/or supplies over harsh terrain (e.g., snow, ice, wetland, etc.) when towed behind a vehicle. The trailer system includes a cabin, first and second skis, and first and second suspension assemblies. The suspension assemblies connect the skis, respectively, with the cabin. The suspension assemblies incorporate multiple pivot points that effectively isolate the skis from cabin, and promote true tracking of the trailer system relative to the towing vehicle. In some embodiments, the cabin has a highly buoyant construction, allowing the trailer system to float in water.

There is provided a snowboard attachment to a standard snowboard for riding under powder snow conditions. The snowboard attachment comprises a nose part, an elongate passage and a body part. The nose part is operable to attach to the standard snowboard for providing lift and float while riding on powder snow. The elongate passage has walls extending between an opening in a top surface of the snowboard attachment and an opening in a bottom surface of the snowboard attachment, and is orientated transverse to the longitudinal axis of the snowboard attachment. The walls of the elongate passage are configured to surround the standard snowboard. The body part is attached in operation to the nose part, and has clamp through openings. The clamp through openings are arranged to receive bolts of a binding clamp of the standard snowboard, such that the clamp through openings lie in operation between the binding clamp and the standard snowboard.

A modular, multi-part roller skate is provided. The multi-part roller skate includes a roller skate body, a front wheel assembly, a rear wheel assembly, a support surface for supporting a footwear of a user, and at least one securing element for securing the footwear to the support surface. The multi-part roller skate is configurable as a modular roller skate with a removable pair of rear wheels, an interchangeable modular roller skate and ice skate, and an interchangeable modular roller skate and cross-country ski/snowshoe. In some embodiments, the multi-part roller skate can also be configured as a length-adjustable skate with a length adjustable skate body that includes separate front and rear foot support structures.

The invention is directed to a graspable human propulsion device which contains a ducted fan assembly on the aft portion of a longitudinal structure which the user grasps onto, which acts to propel the user along the longitudinal direction of the device while the user is mounted on a human transportation apparatus, such as a skateboard. The user can orient the device so that the ducted fan assembly leads ahead or trails behind the user, according to user preference. In one embodiment, the user controls the direction and amount of thrust by use of a spring twist throttle mechanism. In another embodiment, the user controls the direction and amount of thrust by use of a trigger and switch mechanism. The fore latch and the aft latch allow the user to clamp the device onto a skateboard deck for ease in transporting while on foot.

The hybrid snowshoe-ski comprises a rigid frame, a decking attached to the frame and a binding attached to one of the decking and the frame. The decking comprises undulations that each extend between first and second sides of the snowshoe-ski.

A snowshoe-ski kit comprising a hybrid snowshoe-ski comprising a main body defining a bottom surface operative for moving over snow and having a snowshoe-ski traction coefficient, and a top surface opposite the bottom surface. The hybrid snowshoe-ski further comprises a binding attached to the main body for attachment to a person's foot atop the top surface. The kit also comprises a first removable and reversible sheet-like skin having opposite first and second surfaces each defining respective first and second skin traction coefficients that differ from each other and that differ from the snowshoe-ski bottom surface traction coefficient. The first skin is removably attachable to the snowshoe-ski main body with either one of the first and second surfaces bearing against the bottom surface and the other one of the first and second surfaces being exposed, for allowing the snowshoe-ski to be operatively used either alone or with the first skin installed with either one of the first and second skin surfaces exposed.

Some aspects include a ski binding system using controllable electromagnets, alone or in combination with permanent magnets, as means of attaching or releasing a ski boot to a ski during use. Some aspects include a ski binding system using a controllable solenoid. In some aspects, microprocessor-based control releases binding electronically based on input from sensors located in binding, ski and/or boot, as well as in other equipment or clothing connected to them or to skier, or binding releases when a mechanical threshold is overcome. In some aspects, sensor data are recorded for analysis of system performance and for adjustment and improvement of system parameters based on data analytics.
