Abstract
A conveyance device including a frame and at least one wheel coupled to the frame. The device further includes a storage compartment coupled to the frame, where the storage compartment has a pair of opposed side walls configured such that at least a portion of at least one side wall has an upper edge that is less than 49 inches above a bottom of the wheel to enable manual loading of the storage compartment. The conveyance device further includes a conveyor positioned in the storage compartment, wherein the conveyor is positioned to convey items in the storage compartment at least partially upwardly and out of the storage compartment.
Claims20
A conveyance device comprising:
- a frame;
- at least one wheel coupled to the frame;
- a storage compartment coupled to the frame, wherein the at least one wheel is positioned directly below the storage compartment, wherein the storage compartment has a pair of opposed side walls configured such that at least a portion of at least one side wall has an upper edge that is less than 41 inches above a bottom of the at least one wheel to enable manual loading of the storage compartment;
- and
- a conveyor positioned in the storage compartment, wherein the conveyor is positioned to convey items in the storage compartment at least partially upwardly and out of the storage compartment, wherein the storage compartment defines a storage compartment cavity configured to receive the items therein, wherein at least a portion of the storage compartment cavity is positioned vertically below an axle of the at least one wheel when the storage compartment is not in a tipped position wherein the storage compartment is at least partially spaced away from the frame, and wherein the conveyor is generally straight and forms an angle of between about 10 degrees and about 50 degrees relative to a horizontal reference line.

A conveyance device comprising:
- a frame;
- at least one wheel coupled to the frame;
- a storage compartment coupled to the frame, wherein the at least one wheel is positioned directly below the storage compartment, wherein the storage compartment has a pair of opposed side walls configured such that at least a portion of at least one side wall has an upper edge that is less than 41 inches above a bottom of the at least one wheel to enable manual loading of the storage compartment;
- and
- a conveyor positioned in the storage compartment, wherein the conveyor is positioned to convey items in the storage compartment at least partially upwardly and out of the storage compartment, wherein the conveyor is arranged at an angle relative to the upper edge of the at least one side wall, wherein the storage compartment defines a storage compartment cavity configured to receive the items therein, wherein at least a portion of the storage compartment cavity is positioned vertically below an axle of the at least one wheel when the storage compartment is not in a tipped position wherein the storage compartment is at least partially spaced away from the frame, wherein the conveyance device is configured to be primarily conveyed in a forward direction, and wherein the conveyor is positioned and configured to convey items in the storage compartment upwardly and rearwardly, opposite to the forward direction, out of the storage compartment.
2 more elements
A conveyance device comprising:
- a frame;
- at least one wheel coupled to the frame;
- a motor coupled to the frame and operatively coupled to the at least one wheel;
- a storage compartment coupled to the frame;
- a belt or chain conveyor positioned in the storage compartment, wherein the conveyor is positioned to convey items in the storage compartment at least partially upwardly and out of the storage compartment when the storage compartment is in an operating position wherein the storage compartment is positioned adjacent to the frame along a front-to-rear direction of the storage compartment;
- a steering device that is manually operable by an operator to guide movement of the conveyance device;
- and
- an operator-supporting surface coupled to the frame and configured to support an operator thereon in a position in which an average adult-sized operator can access and operate the steering device, wherein the operator-supporting surface is positioned entirely in front of the conveyor, with respect to a direction of movement of the conveyance device and below a center of gravity of the conveyance device when the storage compartment is in the operating position, and wherein the storage compartment defines a storage compartment cavity configured to receive the items therein, and at least a portion of the storage compartment cavity is positioned vertically below an axle of the at least one wheel.
5 more elements
A conveyance device comprising:
- a frame;
- at least one wheel coupled to the frame;
- a storage compartment coupled to the frame, wherein the at least one wheel is positioned directly below the storage compartment, wherein the storage compartment has a pair of opposed side walls configured such that at least a portion of at least one side wall is sufficiently low to enable an average-sized adult person, directly standing on an elevation equal to that of a bottom of the at least one wheel, to manually load items over the at least one side wall and drop the loaded items into the storage compartment;
- and
- a belt or chain conveyor positioned in the storage compartment, wherein the conveyor is positioned to convey items in the storage compartment at least partially upwardly and out of the storage compartment when the storage compartment is not in a tipped position wherein the storage compartment is at least partially spaced away from the frame, and wherein the storage compartment defines a storage compartment cavity configured to receive the items therein, and at least a portion of the storage compartment cavity is positioned vertically below an axle of the at least one wheel when the storage compartment is not in the tipped position.
