Abstract
A braking apparatus for a hand truck that keeps the hand truck stable while lifting or dropping a load from the hand truck. The braking apparatus includes a lever and clamps for pivotally mounting the lever to an axle of the hand truck, and a recoiling mechanism that allows the lever to switch between a deployed position and a non-interfering position. The operator can press the lever against the floor to prevent the rolling of the hand truck while loading.
Claims9
A braking apparatus for a hand truck, the braking apparatus comprises:
- a lever of an elongated and planar profile, the lever has a proximal end and a distal end;
- the proximal end configured to be pivotally coupled to an axle of the hand truck;
- and
- a recoiling member that extends between the lever and a frame of the hand truck, wherein the recoiling member is configured to pivot the lever from a deployed position to an upright non-interfering position, wherein the lever has a pair of rows of apertures running parallel to each other, each row having a plurality of apertures,
- wherein the proximal end is pivotally coupled to the axle using a pair of zip ties, wherein the lever comprises two pair of elongated V-shape holes for the pair of zip ties to pass through, wherein each pair of the elongated V-shape holes comprises two V-shaped elongated slots that are spaced apart from each other and run parallel.
