A waveform reinforced skateboard deck with an intermediate body extending between a nose end and an opposing tail end, the deck further including an outermost top rider bearing surface and an outermost bottom truck mounting surface with at least a portion of at least one of the surfaces having a plurality of spaced apart elongated waveforms defining peaks and troughs projecting along a substantially sinuous path between the nose and tail ends.

A multi-degree of freedom ice skate post that connects an ice skate blade to the sole of an ice-skating boot generally comprises a plurality of adjustable elements that include a pronate/supinate platform, a bi-directional module and a side/side module. In some configurations, the pronate/supinate platform is configured to move the ice skate blade in a pronate and supinate direction. In some configurations the pronate supinate platform is connected with the bi-directional module providing movement of the ice skate blade in the fore and aft position. In some configurations the side/side module is connected with the bi-directional module providing movement in a side by side direction. Additional configurations can include vertical adjustments as well.

A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.

A base for roller skates includes a skeleton and a reinforcing shell. The skeleton is made of a first material through one-time processing and is formed with a plurality of hollow areas. The reinforcing shell includes a plurality of inlaid structures respectively embedded in the hollow areas is directly disposed on the skeleton by injection molding with a second material. The second material is different from the first material. Two roller frame mounting hole sets on the base for roller skates are directly formed by the skeleton, and a brake block mounting hole and a treading platform on the base for roller skates are formed by the reinforcing shell. The base for roller skates is not made of single metal material like prior arts, making it capable of reducing fracture due to the hard and brittle characteristics of the material used in prior art.

An ice skate comprising a blade holder having U-shaped inner and outer members that are spaced apart to define a hollow space therebetween. The U-shaped outer member has an elongated blade-supporting base and front and rear pillars that are spaced apart in a longitudinal direction of the blade holder. At least part of the elongated blade-supporting base, front pillar and rear pillar is made of a composite material such as a fiber-matrix composite material. The ice skate also has a blade comprising a runner and a body made of composite material with a matrix and a plurality of fibers embedded in the matrix.

Fender assemblies are disclosed, each including a rectangular frame defining a central aperture. The perimeter of the central aperture may have a rounded-rectangle shape. A fender arch in the form of an arcuate sheet, e.g., of carbon fiber (CF), terminates on either end at respective first and second flanges extending outward to form a planar base. The arcuate sheet extends through the central aperture to reach above a top side of the frame and the flanges abut a bottom side of the frame. A mud guard is coupled to the rectangular frame through the first flange of the arcuate sheet, such that the mud guard extends from the first flange away from the second side of the frame. The frame and mud guard may be made of plastic, and may be configured to absorb assembly forces to avoid damaging the CF fender arch.

The application relates to a pedal mechanism and a housing of a balancing vehicle. The pedal mechanism comprises a pedal body, and an internal framework is arranged inside the pedal body. A lower side of the pedal body is also formed with an induction probe for inducting a control system inside a balancing vehicle. A housing of the balancing vehicle comprises a pair of symmetrically arranged and relatively rotatable inner housings, the inner housings are connected with the upper housing, and the pedal mechanism installed at upper housing. The pedal body and the induction probe are integrally molded, which has the advantages of less multiple assembly processes, shorter processing time, higher precision, and not easy to fall off which strengthens the stability of the structure.

A system, method, and apparatus for replicating the experience of snow skiing on dry land using a roller land ski with an ability to move and stop consistent with mechanics of an actual snow ski. Each land ski includes a rigid platform with a binding for engagement with a specialized boot, a pair of biased omnidirectional casters supporting said rigid platform, but mounted to a top surface of said platform, and a pair of trucks with a plurality of wheels along its curved axles. A pair of specialized boots constructed out of flexible lightweight material with a stiff support structure to fortify a user's foot and ankle from the forces created by the land ski are included in this system. The method includes calibration and selection of materials for both the board and boot in order to achieve the desired experience.

According to some embodiments, a manually-powered movable device comprises at least one wheel configured to move when a user operates the device, an electrical energy generating assembly, wherein the electrical energy generating assembly comprises a magnet assembly and a coil assembly, wherein the magnet assembly is configured to move when the at least one wheel is moved, wherein the coil assembly is configured to remain stationary relative to a frame of the device when the at least one wheel is moved, and wherein relative movement between the magnet assembly and the coil assembly generates electrical energy, at least one wire assembly coupled to the electrical energy generating assembly, and at least one output device coupled to the at least one wire assembly and configured to contribute to creation of a desired effect.
