ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a folding structure for a skate board scooter that allows the skate board scooter to be folded when not in use.
2. Description of the Related Art
Skate board scooters have recently become popular. A problem for users and manufacturers is the storage and transport of the bulky volume of the skate board scooter when not in use. The present invention is intended to provide a folding structure for a skate board scooter to solve this problem.
SUMMARY OF THE INVENTION
A skate board scooter in accordance with the present invention comprises:
a base having a front end;
a head tube;
a handlebar stem extended through the head tube;
a connecting member extended from the head tube and having a lower end, the lower end of the connecting member including a pivotal hole, a guide hole, and an adjusting hole;
a first mounting wall and a second mounting wall mounted on the first end of the base, the first mounting wall and the second mounting wall being spaced to allow the lower end of the connecting member to pivot therebetween, the first mounting wall and the second mounting wall including aligned arcuate guide holes and aligned pivotal holes, the first mounting wall including a first positioning hole and a second positioning hole, the second mounting wall including a third positioning hole aligned with the first positioning hole, a fourth positioning hole aligned with the second positioning hole, and a connecting slot that communicates the third positioning hole with the fourth positioning hole;
a pivotal pin extended through the aligned pivotal holes of the first mounting wall and the second mounting wall and the pivotal hole of the connecting member;
a quick release rod extended through the aligned arcuate guide holes of the first mounting wall and the second mounting wall and the adjusting hole of the connecting member;
a quick release lever engaged with an end of the quick release rod;
a positioning rod including a first end and a second end, the positioning rod being extended through the guide hole of the connecting member with the first end of the positioning rod releasably engaged in one of the first positioning hole and the second positioning hole and with the second end of the positioning rod releasably engaged in one of the third positioning hole and the fourth positioning hole;
whereby the handlebar stem is in an operative position when the first end of the positioning rod is engaged in the first positioning hole and the second end of the positioning rod is engaged in the third positioning hole, and the handlebar stem is in a storage position when the first end of the positioning rod is engaged in the second positioning hole and the second end of the positioning rod is engaged in the fourth positioning hole.
The second end of the positioning rod is enlarged to be grasped by a user. The first end of the positioning rod is disengaged from an associated one of the first positioning hole and the second positioning hole and moved into the guide hole of the connecting member to allow pivotal movement of the connecting member when the enlarged second end of the positioning rod is pulled out of the second mounting wall. A spring is provided for biasing the first end of the positioning rod into the associated one of the first positioning hole and the second positioning hole. The enlarged second end of the positioning rod includes a reduced section that is removably engaged in an associated one of the third positioning hole and the fourth positioning hole.
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.
