DETAILED DESCRIPTION OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new hand truck device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 6, the hand truck assembly 10 generally comprises a hand truck 12 that has a pair of members 14, a pair of wheels 16 rotatably disposed on the members 14 and a nose plate 18 extending forwardly from the pair of members 14. The nose plate 18 can be positioned beneath an object 20 to transport the object 20 and each of the members 14 has a plurality of engagement points 22 that are distributed along the members 14. Each of the members 14 has a bottom end 24, a top end 26 and an outer surface 28 extending between the top end 26 and the bottom end 24, and the outer surface 28 has a front side 30 and a back side 32. Each of the members 14 has a plurality of openings 34 each extending through the front side 30 of the outer surface 28. The openings 34 are spaced apart from each other and are distributed from a point located adjacent to the bottom end 24 toward the top end 26 such that the plurality of openings 34 defines the plurality of engagement points 22. Furthermore, each of the openings 34 has a bounding edge 36 and the bounding edge 36 of each of the openings 34 has a plurality of intersecting sides 38 such that each of the openings 34 has a rectangular shape.

Each of the members 14 has a curve 40 that is positioned adjacent to the top end 26 such that the top end 26 is directed rearwardly thereby defining a handle 42 for gripping to manipulate the hand truck 12. The nose plate 18 has a rear edge 44 and the rear edge 44 is attached to the front side 30 of the outer surface 28 of each of the members 14 at a point located adjacent to the bottom end 24 of the members 14. Moreover, the nose plate 18 lies on a plane that is perpendicularly oriented with an axis extending between the bottom end 24 and the top end 26 of the members 14.

An axle 46 is provided that has a primary end 48 and a secondary end 50, and the axle 46 is elongated between the primary end 48 and the secondary end 50. The axle 46 has a plurality of brackets 52 each angling away from the axle 46; respective ones of the brackets 52 angles upwardly from the axle 46 and respective ones of the brackets 52 angles downwardly from the axle 46. Each of the brackets 52 has a distal end 54 with respect to the axle 46 and the distal end 54 of each of the brackets 52 is attached to the back side 32 of the outer surface 28 of a respective one of the members 14 such that the axle 46 is perpendicularly oriented with the pair of members 14. The axle 46 is located at a point is positioned proximate the bottom end 24 of the members 14, and a hub 56 of each of the wheels 16 is rotatably disposed on a respective one of the primary end 48 and the secondary end 50 of the axle 46.

A shelf unit 58 is provided and the shelf unit 58 is slidably attached to the members 14. The shelf unit 58 releasably engages respective ones of the engagement points 22 on the members 14 for retaining the shelf unit 58 at a selected point along the members 14. In this way the shelf unit 58 to engage an object that has an elevated lift point 60 to facilitate the hand truck 12 to transport the object that has the elevated lift point 60. The object with the elevated lift point 60 may be a stack of chairs, for example, or any other object that has a lift point that is spaced upwardly from a support surface upon which the object is positioned.

The shelf unit 58 comprises a pair of collars 62 that is each of the collars 62 is slidably positioned around a respective one of the members 14. Each of the collars 62 has an outer wall 64 and each of the collars 62 has a pivot point 66 that is integrated into the outer wall 64. The pivot point 66 on the outer wall 64 of each of the collars 62 is directed away from the front side 30 of the outer surface 28 of the respective member. The shelf unit 58 includes a shelf 68 has a back edge 70 and a bottom surface 72 and the back edge 70 pivotally engages the pivot point 66 on the outer wall 64 of each of the collars 62. The shelf 68 is positionable in a deployed position having the shelf 68 extending forwardly from the pair of collars 62 and the shelf 68 is positionable in a stored position having the shelf 68 extending upwardly from the collars 62.

The shelf unit 58 includes a pair of braces 74 is provided and each of the braces 74 has a coupled end 76 and a free end 78. The coupled end 76 of each of the braces 74 is pivotally coupled to the bottom surface 72 of the shelf 68 and each the braces 74 is aligned with a respective one of the collars 62. The free end 78 of each of the braces 74 extends into a respective one of the openings 34 in the outer surface 28 of a respective one of the members 14 for retaining the shelf 68 at a desired height on the members 14. The free end 78 of the braces 74 abuts a lowermost one 80 of the intersecting sides 38 of the bounding edge 36 of the respective opening for retaining the shelf 68 in the deployed position. In this way the shelf 68 can support the weight of the object with the elevated lift point 60. As is most clearly shown in FIGS. 3 and 4, each of the braces 74 includes a foot 82 that extends rearwardly from the free end 78 and which extends into the respective opening 34.

In use, the shelf 68 is positioned in the stored position to facilitate the hand truck 12 to be employed in the conventional manner having the nose plate 18 carrying an object 20. The shelf 68 is positioned in the deployed position and the collars 62 are positioned at a desired location on the members 14 to position the shelf 68 at the appropriate height to engage the object with the elevated lift point 60. Additionally, the braces 74 are engaged into the respective openings 34 to retain the shelf 68 at the appropriate height. In this way the shelf 68 can be employed to lift and subsequently transport the object with the elevated lift point 60 that the nose plate 18 would not be capable of lifting.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
