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.

The invention concerns a device for controlling a monoski (1), in particular for snow, by means of the combined simple rotation and simple tilting of a single control member such as a handlebar, simultaneously by lateral inclination and by longitudinal twisting. It therefore combines the necessary mechanical functions of a pair of conventional fixtures with the ease of use of a bicycle, and does not require a specific monoski. It makes it possible to move freely on the snow, controlling with both feet held but not locked, or indeed to use one foot to help push on flat terrain and provide stability. The lever arm provided by the control member is considerably superior to that of a pair of conventional fixtures, greatly improving ease of use and the maximum capacities of the device. Finally, it can be quickly folded for ease of handling and storage.

A skate with a stowable and/or removable roller, blade, ski, or track assembly. A skate has: a shoe; a guiding part mounted to the shoe; a roller, blade, ski, or track assembly mounted to move along the guiding part between a deployed position and a stowed position adjacent a calf or ankle part of the shoe; and a handle connected to move the roller, blade, ski, or track assembly between the deployed position and the stowed position. Related methods include moving the roller, blade, ski, or track assembly between the positions, and locking or unlocking the assembly in either position, for example using a handle.

In an aspect, an electrical vehicle for traveling in a forward direction has two wheels on opposing side of a platform without a steering column. A motor and a battery are adapted to drive one wheel and controlled via a fold-out foot control. The steering wheel is controlled via a fold-out foot control. Both the driving wheel and the steering can also be controlled remotely by radio, smartphone app or the like. The two fold-out foot controls are integrated into the general shape of the platform when not in use. The vehicle is equipped with lateral balancing means and connected to a network, which enables it to be driven autonomously.

This invention is directed toward a portable and easy to set up retractable cord system with means to allow athletes to move along specified routes and to form space indicators that show zone areas.

The present invention provides an apparatus for adapting a standard skateboard to add a functional scooter-style handlebar. Through the utilization of the components described herein, a user may convert any standard skateboard to a rolling-board device having a functional handlebar that is capable of receiving rotational force from the user to impact directional motion of the moving rolling-board device. In other words, a skateboard may be converted to a scooter in a manner that is simple and reversible. A preferred embodiment of the apparatus includes: a handlebar for stabilizing a user's balance and for receiving directional input from the user; a spindle for attaching to the truck of the skateboard; and a trunnion having a protruding neck forming a slot for receiving the spindle. An alternative embodiment may additional include a deck stiffener and/or a base plate, both of which may be utilized to reinforce the deck of the skateboard.

A high performance, yet low cost, modular barrier system enables demountable outdoor rinkstypically for ice hockey, or ice skating, or street hockeythat are robust and convenient to install. A rink includes multiple panels, each having a factory-attached link. These panels are linearly disposed, adjacent to one another, to form a piecewise continuous boundary wall enclosing a desired area. Attaching one link to the next, typically via insertion of a thumbscrew, connects the panels into a robust assembly. Both straight and curved panels are provided, thereby enabling a rink with round corners. Each panel includes a shell molded from plastic resin, and has a hollow interior which can be filled with water (or other ballast).

A quick-release truck system includes a deck plate, a truck plate, and a locking mechanism for releasably locking the truck plate to the deck plate. The deck plate mounts to an underside of a deck of a rideable vehicle, and the truck plate mounts to, or is integrated into, an upper surface of a truck baseplate. The deck plate and the truck plate slidingly engage one another using vertically-staggered complementary coupling means. The coupling means may further be horizontally-staggered to create a tiered configuration. The coupling means include a combination of rails and grooves. Once fully engaged, the truck plate releasably locks to the deck plate. The deck plate and the truck plate may include cut-outs for weight reduction.

A foot-deck-based vehicle, a front wheel support, and at least one accessory therefor are provided. The foot-deck-based vehicle has a foot-deck with a front end, a rear end, and at least one rear wheel proximal to the rear end. The foot-deck-based vehicle has a front wheel support comprising a pair of wheel interfaces, each of which is couplable to a front wheel, a main body extending between the wheel interfaces and coupled to the foot-deck, and at least one recess in the main body. At least one accessory is snugly securable within the at least one recess of the front wheel support to modify a resistance of the main body to bending under a bending load applied to the front wheel support through the foot-deck when the foot-deck supports a person.

A retaining wall system for elevating a retaining wall panel of a portable ice skating rink. The retaining wall system includes a first support member and a second support member spaced apart from the first support member. The retaining wall system includes a flexible sheet extending between the first support member and the second support member. The retaining wall system includes a water impermeable liner supported by the flexible sheet. A support member for elevating a retaining wall panel of a portable ice skating rink. The support member includes a base arrangement configured to engage a mounting surface and a height elevating section extending from the base arrangement. The height elevating section having a first receiving area configured to receive a wall panel. A surface extends between the base arrangement and the height elevating section. The surface has a plurality of mounting areas configured to receive a lateral brace member.
