DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular, to FIG. 1 thereof, the preferred embodiment of the new and improved scooter embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described.

More specifically, it will be noted in the various Figures that the scooter 10 includes a contoured frame 12. The frame further includes two rigid and spaced rods 14. Each rod has a front end 16, a rear end 18, a first intermediate rod portion or location 20 defined between the front end and the rear end, and a second intermediate rod portion or location 22 defined between the first intermediate location and the rear end. The front ends of the rods, rear ends of the rods, first intermediate locations of the rods, and second intermediate locations of the rods are planarly offset and aligned with each other. The rods extend downwardly and outwardly in a triangular fashion from the front ends to the first intermediate locations to define a front frame support member 24. The rods then extend horizontally from the intermediate locations to the second intermediate locations. Finally, the rods then extend upwardly and inwardly from the second intermediate locations to the rear ends in a triangular fashion to define a back fork 26 having two spaced prongs 28.

In the preferred embodiment, the back fork extends upward from the second intermediate locations 60 degrees from the horizontal.

A plurality of spaced links 30 are perpendicularly coupled between the rods from the first to the second intermediate locations to define a rear frame support member 32. A rigid plate 34 is coupled to the rear frame support member to define a platform 36 where a user can stand. A portion of the plate near the front frame support member 24 is curved upwardly to help shield a user's feet and legs from road debris. The construction of the frame inherently creates a low center of gravity for the scooter, making it easier to maneuver and control. The frame is reinforced at the curved areas near the intermediate locations to support the weight of an adult.

The scooter includes another pair of rigid and spaced yoke support rods 40. Each rod yoke support has a first end 42 and a second end 44. The first ends of the rods and second ends of the yoke support rods are planarly offset and aligned with each other. The first ends of the yoke support rods are coupled to the front frame support member 24 and extend upwardly and inwardly in a triangular fashion to define a yoke support 46. In the preferred embodiment, the yoke support extends upwardly 30 degrees from the horizontal.

The scooter includes a rigid yoke 50 having an upper end 52 and a lower end 54. The upper end is connected to the front frame support member 24. The lower end is connected to the second ends of the yoke support 46.

The scooter includes a front fork 60. The front fork includes a stem 62 with two spaced prongs 64 extending downwardly therefrom. The front fork is oriented downward at an angle of 30 degrees from the vertical in the preferred embodiment. The stem is disposed within the yoke 50. Both the front fork 60 and back fork 26 are similar to the forks used on conventional bicycles.

The scooter includes a steering column 70 having a upper end 72 and a lower end 74. The lower end is coupled to the stem 62 of the front fork within the yoke 50. Handlebars 80 are coupled to the upper end 72 of the steering column so that the front fork 60 can be directionally pivoted by the operator in relation to the frame 12. The handlebars are similar to those used on conventional bicycles.

A front wheel 90 is mounted between the prongs 64 of the front fork 60 for rotation. The ratio of the vehicle length to wheel diameter is between about 2:1 to 3:1. A back wheel 92 is mounted between the prongs 28 of the back fork 26 for rotation. The ratio of the vehicle length to wheel diameter is between about 2:1 to 3:1. In the preferred embodiment, the wheels used are standard spoked 26-inch bicycle wheels, ensuring ease of replacement thereof since these standard wheels are readily available at most bicycle repair shops. Fenders can be coupled to the frame and placed over the wheels to shield a user from road debris.

A handbrake 100 is coupled to the handlebars 80 and the front fork 60 for applying a braking force to the front wheel 90. The handbrake is similar to those used on conventional bicycles. In the preferred embodiment, the handbrake is a standard bicycle handbrake, ensuring ease of replacement thereof since this handbrake is readily available at most bicycle repair shops. A second handbrake can also be used to apply a braking force to the back wheel.

The scooter is designed to accommodate anyone who is four feet tall or taller, and weighs from about forty five to well over two hundred pounds. The overall length of the scooter in the preferred embodiment is about seventy inches.

A second embodiment of the present invention is shown in FIGS. 5 and 6. The platform 36 of the scooter has a hole 110 disposed thereon. A kickstand 112 is pivotally coupled to the platform with a portion thereof extending through the hole. A user can depress the kickstand from the platform to raise the kickstand and use the scooter.

A third embodiment of the present invention is shown in FIGS. 7 and 8. The platform 36 of the scooter has a hole 112 disposed thereon. A footbrake 116 is pivotally coupled to the platform with a portion thereof extending through the hole. A user can depress the footbrake from the platform to decrease the speed of the scooter.

In a fourth embodiment of the present invention, both the kickstand 112 and footbrake 116 can be coupled to the frame or platform for use with the scooter.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
