Abstract
Abstract A structure of a foot propelled scooter is described. Because foot propelled scooter is put into motion by using foot oscillation, thus creating an effect of exercise and frolic to the rider. The foot propelled scooter has a steering handle which is operatively coupled to a set of front wheels, the steering handle is rotatable in a steering column, a retractable bar is pivotally attached to the steering column, an adjustable rear bar is adjustably and pivotally attached to the retractable bar, a foot frame having a set of wheels disposed underneath is pivotally mounted on each end part of the adjustable rear bar. A foot brake controllable by a foot is mounted on retractable bar. The rider swings both feet alternately in a forward and a backward direction to make a pushing contact to put the scooter into forward motion.

Claim 7
Dependent Claim
54 words
The foot propelled scooter according to claim 1 , wherein the retractable bar comprises a foot brake, the foot brake comprises a plunger, a shaft extending downwardly from the plunger passing through a resilient element and an aperture of the retractable bar, and the lower end surface of the shaft comprises a brake pad.
Claim 8
Dependent Claim
76 words
The foot propelled scooter according to claim 1 , wherein the retraction plates comprises a pivotal aperture and a retraction slit, the retractable bar is pivotally attached to the retraction plates by inserting a fastener through the pivotal aperture and through an aperture in the frontal end bar of the retractable bar and securing the fastener, and secure the position of the retractable bar by securing a fastener on the retractable bar against the retraction slit.
Claim 9
Dependent Claim
110 words
The foot propelled scooter according to claim 7 , wherein when the foot propelled scooter is not in operation, the fastener on the retractable bar against the retraction slit can be loosened and the retractable bar together with the adjustable rear bar can be pushed against the steering handle, the retractable bar together with the adjustable rear bar rotates along the pivotal aperture axis and at the same time the faster on the retractable bar against the retraction slit moves upward along the retraction slit, the faster on the retractable bar against the retraction slit can be secured to secure the retractable bar onto the side of the steering handle.
Claim 10
Dependent Claim
