ABSTRACT:
A type of wheel with a brake device is devised which consists of 2 corresponding housings. A curved trough is facilitated between the inner and outer edges of one of the 2 housings; the curve trough containing a shaft. One end of the shaft touches the inner side of the curved trough whereas the other end touches the inner side of the other housing. The two lateral sides of a secure mount fit over the two lateral sides of the wheel; a wheel axle is inserted through the mount and the housings to form the wheel. A joining device is facilitated at the outer end of the axle which functions to connect the device to other objects such as vehicles, chairs, toddler chairs, etc. A convex shape locking device that fits perfectly in the inner sides of the 2 housings is facilitated in the inner side of the mount so that when the wheel is spinning rapidly, the shaft between the 2 housings swings outward and locks onto the convex device due to centrifugal force which serves to restrict the motion of the wheel and achieves a brake function.
