Latest Patents
Kopman's most notable patent is for a parking brake for hand trucks. This invention features lever-mounted brake pads that are applicable to two non-swiveling wheels at the rear of a hand truck. The brake pads are normally spaced away from the wheel treads by return springs. A foot pedal located at the front of the truck operates between two positions: a 'brake off' position and a 'brake on' position. The design includes cranks connected to the pedal, with links and cables associated with them and the brake pad levers. This allows the pedal to either apply both brakes simultaneously in one position or release them in the other. The return springs maintain tautness in the cables when the brakes are off. An over-center arrangement on the cranks and links, along with a strategically positioned stop in the 'brake on' position, self-energizes to keep the brakes engaged until intentionally released. This innovative design enhances the safety and functionality of hand trucks.
