Abstract:
The invention is directed to novel wheels useful for various products including strollers, vehicles for children, carts, luggage trollies and bags, tricycles, bicycles and toys, and methods of production. The novel wheel comprising a flexible annular segment manufactured by a blow molding process, said segment having at least one layer made of a thermoplastic elastomer; and a wheel hub configured to support the flexible annular segment from each of its sides and to create a cylinder for insertion of an axle therethrough so as to allow connection of the wheel to other components of a product. In one alternative implementation of the invention, the flexible annular segment manufactured is manufactured by extrusion molding process. The invention is further directed to methods for manufacturing the novel wheel.
Abstract:
This presently disclosed subject matter is directed to a bi-directional toy configured to be used as a trampoline and further to be used, upon turning said bi-directional toy upside down, in at least one of the following functions: a playpen-like device, a water pool, and a sphere pool. The toy comprises at least a frame with a plurality of legs configured to elevate the trampoline from a base surface; a bounce mat configured to allow usage of the toy as a trampoline; and the encircling member configured to be attached to the legs for creating a delimited area for use in at least one of the functions.
Abstract:
A tricycle with foldable double wheel assembly comprises: a frame, a single-wheel assembly and a double-wheel assembly respectively disposed at front end and rear end of the frame, and a handlebar assembly matching with the single-wheel assembly to control steering, the double-wheel assembly comprising a supporting beam and two wheels disposed on the supporting beam, wherein the supporting beam comprises two branches of same structures, the two wheels being respectively disposed on the two branches, the supporting beam having a first stable state where the two branches are open, and a second stable state where the two branches are put together side by side. The supporting beam in the double-wheel assembly of the present utility model is foldable so that it is not necessary to occupy a relatively large space to carry/store the tricycle and the usage convenience of the tricycle is thus improved.

Abstract:
The present invention discloses a tricycle having two riding modes, the tricycle comprising: a frame, a single-wheel assembly and a first handlebar mounting base that are disposed at one longitudinal end of the frame, a double-wheel assembly and a second handlebar mounting base that are disposed at the other longitudinal end of the frame, a transmission mechanism disposed between the second handlebar mounting base and the first handlebar mounting base, and a handlebar assembly selectively disposed on the first handlebar mounting base or the second handlebar mounting base, the single-wheel assembly comprising a steering wheel and a first pedal for driving the steering wheel to roll, the double-wheel assembly comprising two wheels widthwise spaced apart and a second pedal for driving the two wheels to roll. The tricycle has a first riding mode with single front wheel and double rear wheels and a second riding mode with double front wheels and single rear wheel. The tricycle of the present invention may easily switch between two riding modes and may increase the fun of riding.
