FIELD OF THE INVENTION




The present invention relates generally to a light vehicle for amusement and exercise, and more particularly to a light vehicle for gliding on snow or ice.




BACKGROUND OF THE INVENTION




The scooter is a popular light vehicle for riding on the ground for the purpose of amusement and exercise. In light of the unique characteristics of the scooter, the scooter may be modified in a manner that it can be used for gliding on snow or ice for the purpose of amusement and exercise. Such a modified scooter as described above is called “snowscooter”.




BRIEF SUMMARY OF THE INVENTION




The primary objective of the present invention is to provide a light vehicle which is designed for gliding on snow or ice for the purpose of amusement and exercise.




In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a light vehicle comprising a footboard with a runner at each longitudinal end thereof, a raised handlebar for steering, and a braking device.




The features and the advantages of the light vehicle of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




As shown in

FIGS. 1-6

, a light vehicle “A” embodied in the present invention is intended for gliding on snow or ice for the purpose of amusement and exercise and is formed of a footboard


10


, a raised handlebar


11


for steering, a rear runner


20


, a front runner


21


and a braking device


30


.




The handlebar


11


is fastened pivotally with the front end of the footboard


10


. The front runner


21


is fastened with the bottom end of the handlebar


11


. The rear runner


20


is fastened with the underside of the rear end of the footboard


10


in conjunction with the braking device


30


.




The rear runner


20


and the front runner


21


are basically similar in construction and are arcuate in the longitudinal section. The rear runner


20


and the front runner


21


are provided in the center of the underside with a guiding projection


22


, in two opposite fringes with a steering projection


23


and a braking tip


25


extending from the steering projection


23


, and a snow guiding recess


24


located between the guiding projection


22


and the steering projection


23


. The guiding projections


22


of the rear runner


20


and the front runner


21


serve to guide the gliding direction of the light vehicle “A” of the present invention. The steering projections


23


of the 'rear runner


20


and the front runner


21


are used at such time when the light vehicle “A” is tilted to make a turn or negotiate a curve, as illustrated in

FIGS. 8 and 9

. The braking tips


25


of the rear runner


20


and the front runner


21


serve to reduce the speed of the light vehicle of the present invention by making contact with the snow or ice at the time when the light vehicle “A” in motion is making a turn or negotiating a curve.




The guiding projections


22


of the rear runner


20


and the front runner


21


are provided with two guiding edges


223


opposite to each other, and a guiding recess


221


located between the two guiding edges


223


. The guiding edges


223


are capable of cutting into the ice surface to guide the gliding direction of the light vehicle “A” of the present invention.




As shown in

FIG. 3

, when the light vehicle “A” of the present invention is gliding on the snow, the guiding projection


22


sinks deeper into the snow while the two steering projections


23


work to guide the gliding direction of the light vehicle “A” of the present invention.




The braking device


30


comprises a trigger plate


31


, a guide tube


32


located between the rear end of the footboard


10


and the rear runner


20


for receiving a link rod


33


which is provided at the bottom end with a brake shoe


34


fastened therewith, and at the top end with a stop piece


36


. A spring


35


is fitted over the top end of the link rod


33


such that one end of the spring


35


is stopped by the stop piece


36


which is in contact with the underside of the trigger plate


31


, and that other end of the spring


35


is stopped by the top end of the guide tube


32


. The guide tube


32


is fastened to the rear end of the footboard


10


. The rear runner


20


is provided with a through hole


41


corresponding in location to the brake shoe


34


. When the trigger plate


31


is exerted on by an external force, the brake shoe


34


is forced to make contact with the snow or ice via the through hole


41


of the rear runner


20


, thereby resulting in a braking effect on the light vehicle “A” in motion. It must be noted here that the trigger plate


31


is fastened at one end with the footboard


10


such that the trigger plate


31


is forced by the recovery force of the spring


35


to return to its original position at the time when the trigger plate


31


is relieved of the external force exerting thereon.




As shown in

FIG. 6

, the braking device


30


of the present invention comprises two brake shoes


34


to enhance the braking effect of the braking device


30


. These two brake shoes


34


are fastened to the free ends of two arms


40


which are extended from the link rod


33


.




As illustrated in

FIG. 7

, the light vehicle “A” of the present invention is moved by a rider on snow or ice. It is moved by a series of pushes made by one foot of the rider against the snow or ice.




The present invention described above is to be regarded in all respects as being illustrative and nonrestrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scopes of the following claims.
