Abstract

A manually operated cart that is specifically designed for loading, hauling and unloading long and heavy objects such as pipe, wood poles and heavy construction members without requiring the user to manually lift the objects for either loading or unloading and a method for loading, transporting and unloading a wheeled manual cart of this nature. For loading a long and heavy object, the cart manipulation handle is positioned in a lateral handle receptacle and is used by a worker to roll the cart over to an inverted position on top of the long and heavy object to be lifted and transported and after being bound to the object, is rolled back to its wheel supported position with the object so attached. After the cart and object have been manually moved by manual pushing or pulling, the worker will unload the cart by returning the cart manipulation handle to the lateral handle receptacle and by using the handle as a fulcrum to rotate the cart back to its inverted position and thus returning the object to the ground or floor. In this position the cart/object binding is released to allow the cart to be removed from the object. During cart rotation, rounded sections of an object support cradle of the cart will serve as fulcrum points for control of cart and object rotation by the laterally connected handle.

Claims16

Dependent claims

A method for manually loading, transporting and unloading objects, comprising:

(a) providing a wheeled cart having a wheel supported position for transporting objects, having an object support framework, having a removable elongate handle, a first handle receptacle for receiving said removable elongate handle for pushing and pulling movement of said wheeled cart and a second handle receptacle being oriented in transverse relation with said first handle receptacle and further having retainer means for retaining said object to said wheeled cart;
(b) inverting said wheeled cart over said heavy object;
(c) with said retainer means, securing said wheeled cart and said object assembly;
(d) locating an end portion of said elongate handle within said second handle receptacle
(e) with said elongate handle as a lever laterally rotating said wheeled cart and said wheeled cart and said object in assembly therewith from said inverted position of said wheeled cart to said wheel supported position thereof
(f) positioning said end portion of said elongate handle within said first handle receptacle;
(g) using said elongate handle moving said wheeled cart and said object retained in assembly therewith to a described location;
(h) locating said end portion of said handle within said second handle receptacle;
(i) using said elongate handle as a lever, rotating said wheeled cart and said object to the inverted position of said wheeled cart;
and
(j) releasing said retainer means to thus release said object from assembly with said wheeled cart.

8 more elements

A manually operated wheeled cart for loading, transporting and unloading objects, comprising:

(a) a cart framework;
(b) at least one wheel axle being fixed to said cart framework;
(c) at least one pair of wheel assemblies being rotatably connected to said wheel axle and providing for wheel supported movement of said wheeled cart on a surface;
(d) means for supporting an object on said wheeled cart
(e) means for retaining an object in assembly with said wheeled cart
(f) a first handle receptacle being fixed to said cart framework and being oriented for handle operated pushing and pulling movement of said wheeled cart on a surface
(g) a second handle receptacle being fixed to said cart framework and being oriented generally parallel to said wheel axle and in transverse relation with said first handle receptacle;
and
(h) an elongate handle being selectively positionable within said first handle receptacle for pushing and pulling movement of said wheeled cart on a surface and being selectively positionable within said second handle receptacle for lateral rotation of said wheeled cart from a wheeled supported position to an inverted position, while using said handle as a lever.
