ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a foldable skate board scooter.
2. Description of the Related Art
A typical skate board scooter includes a board with front and rear wheels attached to an underside thereof and a steering column mounted to the front wheel for steering. The skate board scooter is foldable to provide convenient carriage and storage. Yet, the structure is too complicated and the handles on the steering column cannot be retained in place reliably.
The present invention is intended to provide a foldable skate board scooter to solve this problem.
SUMMARY OF THE INVENTION
A foldable skate board assembly in accordance with the present invention comprises:
a board having a front wheel and a rear wheel attached thereto,
two mounting seats mounted on the board and each including a first notch and a second notch,
a steering column including a lower end attached to the front wheel to move therewith and an upper end, the steering column including an inclined extension pivotally connected between the mounting seats by a pivotal pin,
two handles attached to the upper end of the steering column,
a slider slidably mounted to the inclined extension of the steering column,
a positioning member mounted to the slider to move therewith, and
an elastic element attached between the pivotal pin and the slider,
whereby the slider is slidable between a first position in which the positioning member is engaged in the first notches of the mounting seats, thereby retaining the steering column in an operative status and a second position in which the engaging member is engaged in the second notches of the mounting seats, thereby retaining the steering column in a folded status.
The inclined extension of the steering column has an inclined upper surface. The inclined upper surface has two guide slots and the slider includes two lugs slidably extended through the guide slots, the lugs having aligned holes through which the positioning member extends. The inclined extension includes two lateral sides each having a slot through which the positioning member extends. The slider further includes a pull-tab for manual operation.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
