1. A cart comprising:
a. a base section formed in a single piece of material including a bottom horizontal section having a left side and a right side, the bottom horizontal section respectively extending on the left side to a left arcuate section which extends to an elevated left horizontal section, and extending on the right side to a right arcuate section which extends to an elevated right horizontal section; b. a first lower handle section which is formed in one piece as an elongated U-shaped member having a horizontal section which extends from its left side to a lower vertical left leg member and which extends from its right side to a lower vertical right leg member, the lower vertical left leg member ending at a distal end and the vertical left leg member has two transverse openings extending through it, a first left transverse opening adjacent its horizontal section and a second left transverse opening adjacent its distal end, and the lower vertical right leg member ending at a distal end and the vertical right leg member has two transverse openings extending through it, a first right transverse opening adjacent its horizontal section and a second right transverse opening adjacent its distal end, a protective sheath surrounding a portion of the horizontal section; c. a second upper handle section which is formed in one piece as an elongated U-shaped member having an upper generally U-shaped member which is covered by a grip covering member which grip covering member has a left distal end and a right distal end, the upper U-shaped member extends to an upper vertical left leg member and to an upper vertical right leg member, a crossbar extends across an interior of the upper handle section and is affixed to upper vertical left leg member and upper vertical right leg member at a location adjacent the right distal end and the left distal end of the grip covering distal ends and extends transverse to the upper vertical left and right leg members, the upper vertical left leg member has a distal end, a section of the upper vertical left leg member adjacent its distal end is bent at an angle relative to the upper vertical left leg member, a transverse opening extends across upper vertical leg section adjacent its distal end, the upper vertical right leg member has a distal end, a section of the upper vertical right leg member adjacent its distal end is bent at an angle relative to upper vertical right leg member, a transverse opening extends across upper vertical leg section adjacent its distal end; d. a toe plate which has a honeycomb pattern with a multiplicity of openings separated by horizontal solid sections and vertical solid sections, the toe plate rests on and is affixed to the elevated horizontal sections of the base member so that the toe plate is elevated above the horizontal base member, the toe plate rotatably retained to the elevated horizontal sections of the base member; e. a left bumper wheel with a rubber tire having a diameter of approximately four inches and an oppositely disposed right bumper wheel with a rubber tire having a diameter of approximately four inches, a horizontal mounting bar retaining rotational affixation members to rotatably retain the toe plate, the horizontal mounting bar extending through aligned openings in the lower vertical left leg member and lower vertical right leg member, the horizontal mounting bar further rotatably supporting the left bumper wheel and the right bumper wheel in a manner where one-half the diameter of the left bumper wheel is aligned with the toe plate and one-half the diameter of the right bumper wheel is aligned with the toe plate; f. the upper handle section is rotatably connected to the lower handle section by a left rotatable affixation member extending through aligned transverse openings in the lower left vertical leg member and the bent section of the upper left vertical leg member and by a right rotatable affixation member extending through aligned transverse openings in the lower right vertical leg member and the bent section of the upper right vertical leg member, in an erect condition, the rotation of the upper handle section relative to the lower handle section is rotated so that the upper handle section is adjacent and above the lower handle section and in a folded condition, the rotation of the upper handle section relative to the lower handle section is in an opposite direction so that the upper handle section is within the lower handle section and the gripping member of the upper handle section rests against an interior wall of the toe plate section; g. the toe plate rests on the elevated left and right horizontal sections of the base member when the cart is in the erect condition and the toe plate is rotatably connected to the lower handle section and is rotated to lie against the lower handle section when the cart is in the folded condition; and h. a locking tab is rotatably connected to the cross-bar in the upper handle section, the locking tab has a locking member at one end which grips a transverse member of the toe plate so that when the cart is in the folded condition, the locking tab serves to securely lock the cart in a folded condition for safe storage. |
