Embodiments of moving wheel platforms that minimizes wheel interactions with noncontinuous and uneven surfaces are described herein. Further, embodiments of moving wheel platforms with rotation-inhibiting structure are described herein. Implementing rotation-inhibiting structures onto or into the moving wheel platforms aids with eliminating wheel bite. Other embodiments can be described and claimed.

The present invention relates to sports equipment, namely, to roller skates design enabling an athlete to achieve high speed of movement with better comfort and improved motion control, in particular, in case of movement on a lower quality road surfaces. Roller skates consist of two skatesright and left ones, each comprising a spatial rectangular frame with its upper surface adapted to be attached to a frame of the corresponding shoe, either left or right one, and its lower side having two pairs of rollers pivotally attached thereto such that the rollers may rotate being in contact with the roadway and the rollers' axes are parallel to the frame plane, and according to the invention each pair of front and rear rollers of each skate is pivotally attached to the corresponding Z-shaped wheel arm, either front or rear one, which has its central section pivotally attached to the corresponding smaller side of the spatial rectangular frame, and the distance between the axes of the inner rollers of a skate is greater than the distance between the axes of the external rollers. The present invention is aimed to provide such roller skates, which would be more reliable and safe due to increased stability of the skates during movement, also in case of lower quality road surface and during cornering. This objective is achieved by way of creating conditions for uniform distribution of the load arising from the weight of the athlete during movement among all four rollers of each skate, even when moving on a lower quality road surface.

The present invention provides a motorized skate having a balance control system adapted to maintain fore-and-aft balance of a platform of the skate about a wheel arrangement. The wheel arrangement defines a pivot point for the platform. A motor arrangement is adapted to drive the wheel arrangement so as to allow for the balance control system to maintain fore-and-aft balancing of the platform about the wheel arrangement.

Disclosed is a bionic electric power-driven shoe, comprising a shoe sole (1), wherein a plurality of rotating wheels (2) are arranged below the shoe sole (1); an electric motor (3) is further provided at a lower part of the shoe sole (1); an output end of the electric motor (3) is connected to a transmission device in driving connection with the rotating wheels (2); and the shoe sole (1) comprises a heel part (11) and a sole part (12), the heel part (11) and the sole part (12) being in rotational connection.

This invention relates to an improved wheel arrangement of an inline skate for improving turning capability. In this wheel arrangement, the front wheel and rear wheel and any middle wheels are disposed along a straight line that makes an acute angle with the rolling direction and with the wheels being arranged such that they are part of a substantially inverted V-shape seen in front or rear plan view. Subject of the invention are a frame, a wheel assembly, combinations of left and right frames and wheel assemblies, inline skates, a method for retrofitting a prior art frame and a replacement mount for use in such a method.

Disclosed is a folding car for children. The folding car comprises a rear frame, rear frame is connected with a seat; a front frame connected to the rear frame in a back-and-forth movable manner; a front lateral rod, a front portion of which is rotatably connected with the front frame; a rear lateral rod rotatably connected to the front lateral rod and the rear frame; a pedal rod rotatably connected to the front frame; and a connecting rod connected with the rear frame in a back-and-forth movable manner, and a front portion of the connecting rod being connected with the pedal rods in a slidable and rotatable manner. The folding car for children realizes the folding of a seat-type scooter for children, has a simple and new overall structure, is convenient to fold and has a small volume after being folded.

A transformable skate is provided, including: a shoe body; a frame, connected to the shoe body; at least one first fork support, connected to the frame on which at least one first wheel is mounted; and an adjustable assembly, including a base and at least two second fork supports on which at least two second wheels are respectively mounted, the base being adjustably positioned to and blocked by the frame and the at least two second fork supports being each adjustably positioned to and blocked by the base so that the at least two second fork supports are constructed and arranged to position the at least two second wheels in an inline arrangement or in a parallel arrangement.
