A modular field that includes a plurality of coplanar wall segments connected together by a plurality of stanchions and a plurality of corner stanchions to connect together wall segments oriented perpendicular to each other. The size of the modular field may be varied by the number and/or size of wall segments. Lights may be connected to the corner stanchions. One or more doors to allow ingress into the modular field may be connected to adjacent wall segments by the stanchions. Goals may be connected to wall segments at opposite sides of the modular field by the stanchions. The stanchions may include a base plate, a main support pole connected to the base plate, a channel receptacle connected to the base plate, a rear plate connected to the main support pole, a frame connected to the rear plate, a front plate, and a clamp connected to the main support pole.

A motorized personal transportation article is described which transports a person by wearing a pair of power-assisted motorized shoes, wherein the shoes provide an increase in a user's walking speed in a forward walking action through supplementary motion of moving or propelling means based on an intended walking speed of the user, such that when a user's intended walking speed changes or when a user intends to substantially decelerate or immobilize, the speed of the supplementary motion can be adjusted before the step is completed. The sole of each of the shoes houses at least one plate coupled to moving or propelling means such as conveyor assemblies, and the moving or propelling means are designed to neutralize forces acting to disrupt the operation of the moving or propelling means during a forward walking action or the balance and comfort of the user.

A sports ball rebound and boundary system including at least one portable post portion, configured to in use stand upright unsupported, and a barrier portion. The post portion and the barrier portion are configured for mutual releasable connection so that at least part of the barrier portion is extendible from the post portion to form a substantially vertically aligned planar barrier extending upwards from substantially ground level. The barrier portion is further configured to in use remain under sufficient tension to cause a ball or similar to rebound when striking the barrier.

In a preferred embodiment a wheeled platform apparatus and method for use in rolling on a surface are provided. The apparatus includes a platform having a top surface, a bottom surface, a front portion, a center portion, a rear portion, and a first wheel and a second wheel that interface with or are positioned below the bottom surface of the platform to facilitate rolling movement of the platform. The apparatus may further include an attachment device interfacing with the top surface and the footwear, as well as a footrest to support the forefoot of another foot, or footwear.

The present invention discloses an automatic telescopic pole, which comprises a first pole section having an upper end and a lower end; a second pole section telescopically disposed inside the first pole section; a handle disposed on the upper end of the first pole section; an elastic member disposed between the second pole section and the first pole section; a clasp-type telescopic locking device disposed between the second pole section and the first pole section; a driving rod having an upper end and a lower end, and disposed in the clasp-type telescopic locking device along a longitudinal direction of the first pole section; wherein, a button mechanism having a button is disposed on the handle; and, a lock catch is slideably disposed on the handle and in front of the button mechanism.

A new wall rack includes first and second mountable brackets, each including a plurality of spaced arms extending outwardly from the bracket for supporting items thereon. One or more arms of each bracket include a pivotable extension deployable to support wider items and storable when not needed.

A collapsible mobile stage may be folded into a configuration and the shape of a trailer that may be hauled by a truck. The collapsible mobile stage includes an elevated framework supported by telescoping columns. The elevated framework may be used to support lighting, audio and visual systems. The mobile stage also provides seating for an audience on either side of a central stage supported by a platform. The platform includes a central segment between two opposing lateral segments. The lateral segments may be folded up to form the sides of a trailer while the central segment forms the bottom of the trailer. Audience seating sections may be folded over the platform segments to create the roof of the trailer. Audience seating as well as the elevated framework may be stored within the trailer or within a secondary trailer.

An apparatus comprising a platform; a plurality of trucks coupled to the platform; and a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation, wherein the roller assembly is configured for an elastic biasing, wherein the roller assembly is driven by a motor.

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 skateboard that can be converted between a scooter and a skateboard has a bracket that is pivotably mounted on the footboard and can be pivoted between a first scooter position and a second skateboard position. The bracket is longer than the footboard by an amount, so that, in the skateboard position, the bracket forms a clearance between itself and the end of the footboard that is sufficiently large as to enable the skateboard to be gripped through said clearance and carried.
