| The skateboard is a generally plastic, rectangularly shaped with rounded corners strip with wheels attached to the underside that a person stands upon and can move from place to place. A person can also perform tricks while riding a skateboard such as spinning the board in the middle of riding. This particular patent is for a skateboard with a built in braking mechanism. Previous skateboards either had no braking mechanisms, so a person would have to jump off a moving skateboard if they lost control, or inefficient braking mechanisms such as a block attached to the bottom end of the back or a pedal that activated wheel brakes. This patent's braking mechanism allows the user to simply shift their weight toward the back of the skateboard while riding in order to brake. When the weight is shifted, the rear wheels engage the brake shoes, which slow down the wheels. This patent was issued on Nov. 18, 1980.
