ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is related to a steering mechanism of handle-controlled skate board. When the handle-controlled skate board is laterally tilted, the wheel assembly is horizontally steered in a laterally tilting direction.
FIG. 11
shows an existent handle-controlled skate board
7
including a skate board
71
, two wheels
72
respectively mounted at front and rear ends of the skate board
71
and an upright handle
73
mounted on front end of the skate board
71
. A user can stand on the skate board
71
to ride the handle-controlled skate board
7
. Such handle-controlled skate board
7
has some shortcomings as follows:
First, in order to enable a user to easily stand on the skate board and conveniently carry the handle-controlled skate board
7
, the wheels
72
are designed with very small dimension. However, the front wheel
72
is directly controlled by the handle
73
to steer the handle-controlled skate board
7
. The user can hardly stably control the front wheel and there is potential danger when riding.
Furthermore, when steering the handle-controlled skate board
7
, in order to avoid excessively large turning angle, the user's body can hardly coordinately steer the handle-controlled skate board
7
. Therefore, the existent handle-controlled skate board
7
can only run straightly and it is impossible for a user to perform figure skate with such handle-controlled skate board
7
.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a steering mechanism of handle-controlled skate board, in which at least one wheel assembly can be steered according to the tilting angle and direction of the skate board. Also, the handle-controlled skate board is able to bear greater load and a user can perform figure skate with the handle-controlled skate board.
The present invention can be best understood through the following description and accompanying drawings wherein:
