  • a base;

    a set of parallel wheels;

    a brake arm that is hinged to the base and pivots between a) an engaged position in which part of the brake arm acts to retard rotation of one of the parallel wheels and b) a disengaged position in which the brake arm is disengaged from the wheel;

    a spring that biases the brake arm to the disengaged position;

    an operator-engagable lever that pivots between a) a locked position in which a part of the lever presses the brake arm into the engaged position and b) an unlocked position in which the part of the lever that presses the brake arm into the engaged position is in a different position, enabling the spring to move the brake arm into the disengaged position.
