Abstract

A rolling platform designed to attach and detach to a juvenile stroller that allows a second small child to ride along in a standing position. The platform is attachable and detachable to the rear axle or frame, or any stroller part thereof deemed suitable for the purpose of attaching and subsequently towing the rolling platform in a safe and solid fashion. The platform has one set of two polyurethane wheels in axial alignment fixed to the underside of the rear of the platform with a bolt and rubber coupling assembly located at the front of the topside of the platform designed to attach to the rear axle or frame of the stroller.

Description

JUVENILE STROLLER ROLLING PLATFORM
This invention provides an improvement and adaptation of a ride-along rolling platform commonly called a skateboard for the purpose of attaching and detaching from a juvenile stroller.
BACKGROUND OF THE INVENTION
Skateboards have been a popular juvenile (and most recently adult) piece of sporting equipment for the past twenty years. Traditionally made from sandwiched laminated layers of thin wood stock (commonly called plywood) or moulded plastic with dual wheel bolt assemblies affixed to the underside, skateboards provide simple self propelled transportation. Although traditional skateboards are designed to allow freestanding, self propelled transportation, this invention illustrates an improvement to the traditional device that allows a small child to experience the skill and balance of skateboarding while being pulled behind a common juvenile stroller powered by and under the direct guidance and supervision of an adult.

SLtMMARY OF THE IIWENTION
Skateboards and similar devices are considered self propelled, self-directed.
Consisting broadly of a laminate wood or plastic deck with two pairs of wheels arranged in axial alignment mounted on a bearing and axle system. This invention allows a small child to experience the balance and skill of the correct and safe use of a skatel~rd while being safely pulled by a juvenile stroller under the guidance and operation of an adult. This invention mimics in style, build, and construction that of a common skateboard but allows for a different application of that previous invention by way of its distinct mounting application and system.
This mounting system allows for easy attaching and detaching of the juvenile stroller rolling platform by hand and without the use of tools by a supervising adult. The distinct mounting system, coupled with the evolved design of the rolling platform based on the common skateboard, allows for the safe experience of balance and motion by a child while an adult provides the propulsion by pushing the reauisite juvenile stroller in a safe and orderly manner.
In the drawings, which form a part of this specification, Fig. 1 is a side elevational view, with all specification in view, illustrating the distinct design and systems that form the patent of this invention.

DETAILED DESCRIPTION OF THE INVENTION
This rolling platform allows a small child to ride along the rear of a juvenile stroller while an adult pushes the juvenile stroller.
The platform itself is comprised of a section of laminate plywood consisting of S to 7 layers measuring to a total thickness not less than lcm but not more than l.9cm. The platform measures 33cm at its widest point, and 1 lcm at its narrowest. The topside is affixed with a material consisting of an adhesive an one side (which adheres to the surface of the platform) with a firmly placed mixture of silica and sand (commonly coloured black) affixed to the topside allowing the rider firm grip and traction the top of the rolling platform with the soles of their shoes.
At the top and front of the invention is a bolt and rubber coupling assembly system that allows the rolling platfonm to be quickly and easily attached or detached to the rear axle or frame of the juvenile stroller without the use of tools. The bolt and rubber coupling assembly (herein referred to as the mounting bracket or mounting system) is connected to the top and front of the invention by a 90degree metal angle plate and a nut and bolt system that fastens through the thickness of the platform. Extended from and attached to the metal angle plate by a nut and bolt system is a rubber coupling that acts as a strong but flexible and constant extension for the mounting bracket. The rubber coupling is finished with a second 90degree metal angle plate attached by a nut and bolt system. This final angle plate is affixed to a suitable and firm portion of the juvenile stroller frame or axle by a nut and bolt system fastened through a flat plate. A
knob, or thumbscrew comprised of 3 wings and made from hardened resin is used as the bolt thereby allowing the installing person to apply suitable torque to the tightening of the bolt.
On the underside of the rolling platform are two polyurethane wheels in axial alignment.
The wheels are held in place with a bolt and nut system and rotate on a system of dual ABEC 1 or ABEC 3 encased bearings. The axial alignment is constructed of aluminium and is held in place with four bolts placed through the topside and held by four corresponding nuts on the undercarnage of the alignment system. The axial system is further constructed of a bolt and bushing system that allows for small amounts of flex across the lateral axis of the rolling platform thereby affording consistent traction and suspension to the rolling platform whilst it is in motion and under load.

Claims

1. In a rolling platform resembling a common skateboard that allows for the attachment and detachment to a suitable portion of a juvenile stroller.

A shortened and distinct rolling platform supported by two polyurethane wheels arranged in axial alignment.

A forward and top-mounted metal plate and rubber coupling mounting system that allows the rolling platform to be attached to a juvenile stroller so that the rolling platform may be towed and thereby propelled by the pushing of said juvenile stroller.

A thumbscrew, or resin knob and nut system that allows for the simple and easy attachment and detachment of the rolling platform to a suitable member of a juvenile stroller without the use of tools.

2. The combination defined in claim 1 with the rolling support of two polyurethane wheels arranged in axial alignment mounted with a bearing and axle system, supported by a polyurethane bushing to allow for suspension and traction. The axle system is constructed of aluminium and fixed to the platform by means of four nuts and bolts, which fasten through the thickness of the platform.

3. The combination defined in claim 1 with a forward and top mounted 90degree angled metal plate affixed to the rolling platform by way of a nut and bolt assembly.

4. The combination defined in claim 3 with a rubber coupling that allows for constant, safe and flexible extension attached by a nut and bolt assembly.

5. The combination defined in claim 4 attached with an 90degree angle metal plate by a nut and bolt assembly, which in turn may be attached and detached to a suitable portion of the axle or frame of a juvenile stroller and held firmly in place by means of a resin or plastic thumbscrew or similar knob and nut.
