Abstract
A nestable cart, of the type guided by a walking attendant, for conveying a material such as luggage. The cart has a frame and is supported by two rear wheels and a front rotatable caster. A brake is contained within each rear wheel. The brake is automatically engaged when the cart is left unattended. Movement of the handle disengages each brake. A cable connected between the handle and brake linkage disengages the brake shoe, allowing each wheel to freely rotate.
