First Reference- Pedal Braking
Patent number: 4037852 was filed on March 17, 1976 and issued on July 26, 1977. It is for a braking mechanism for a skateboard that consists of a pedal placed on the top of the skateboard that activates the brakes when stepped on by the user. The pedal is attached to a lever that is attached to the braking element on the underside of the skateboard. When pressed, the pedal pushes the rod, which pushes the braking element onto the rear wheels of the skateboard, causing the skateboard to stop. The more pressure the rider applies to the pedal, the more force applied to the brakes. The pedal is held in the depressed position by a spring, so after pressure is done being applied to the pedal, it returns to the depressed position.
Another configuration causes the braking to be caused by pressure on the interior vertical surfaces of the rear wheels instead of directly on top of the wheels. When the pedal is pressed, two pins come into contact with the vertical surfaces to cause braking.
According to the inventors, there were no prior inventions for braking mechanisms for skateboards at the time they filed their patent application. They also claimed that there was a need for a skateboard braking mechanism due to injuries riders received from not being able to stop their skateboards, especially on hills.
In the case analyses, this reference will be referred to as the pedal braking invention.
Second Reference- Braking/Steering
Patent number: 4094524 was filed on October 18, 1976 and issued on June 13, 1978. It is for a braking and steering system that consists of a u-shaped bar with brake shoes on the ends that are activated by pressure on an arm located above the board. The arm’s location above the board and slightly to the side allows it to be easily accessed by the rider’s foot. When pressed, the arm presses down the u-shaped bar, which presses the brake shoes onto the rear wheels of the skateboard, causing the skateboard to slow down. A leaf spring on the u-bar causes the brake shoes to move away from the wheels when pressure is not placed on the arm. The braking and steering system can be attached to the skateboard simply by placing the u-bar between the truck and the board and attaching it using the same fasteners for the truck.
The brake shoes do not necessarily have to engage both of the rear wheels. In order to steer by braking only one wheel, the rider simply needs to lean to the side of the wheel they want to stop while pressing the arm. For example, to stop only the left rear wheel, the rider needs to lean slightly to the left and press the arm more outwards than down. To stop only the right rear wheel, the rider needs to lean to the right and press on the arm. This ability to brake only one wheel allows for easier turns and steering.
The inventor expresses a need for a braking system on skateboards in order to reduce injuries and the wear and tear on shoes that is commonly found among skateboarders.
In the case analyses, this reference will be referred to as the braking/steering invention.
