DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Conventionally, wheelbarrow assemblies are retailed assembled, which may require preassembly by the manufacturer, or the retailer. Assembled wheelbarrow assemblies require significant retail space in order to house and display the wheelbarrow assemblies to consumers at the retail location. The prior art has also provided wheelbarrow assemblies that are packaged and shipped in multiple boxes. Multiple boxes create additional cost and inconvenience to the customer. Reducing the packaging size allows manufacturers to streamline direct to consumer shipping capabilities. In order to fit all the wheelbarrow assembly components in one box, while minimizing an overall size of the box, a multi-piece handle assembly is offered.

FIGS. 1-3 illustrate a wheelbarrow assembly 30 according to an embodiment. As depicted, the wheelbarrow assembly 30 is a single-wheeled manually operated and driven vehicle with a tray 32 for carrying and transporting loads. The wheelbarrow assembly 30 is employed for gardening, construction, yardwork, home improvement projects, and the like.

The wheelbarrow assembly 30 is provided with a tray 32, a pair of handle assemblies 34, and a wheel 36. A pair of upright support brackets 38, a pair of angled brackets 40, and a pair of legs 42 connect to the tray 32. The pair of handle assemblies 34 are mounted to the angled brackets 40 that are connected to the tray 32. An end bracket 41 is connected to the pair of handle assemblies 34. A pair of bushings 44 are mounted to the pair of handle assemblies 34 and the wheel 36 is mounted to an axle 45 in the bushings 44. The wheel 36 connects to the tray 32 for rotation relative to the tray 32 and is used for transportation of the tray 32 upon an underlying support surface, such as the ground or a floor. The upright support brackets 38 are positioned on either side of the wheel 36. Additionally, the pair of legs 42 is provided with a cross-member 46.

Referring to FIG. 3, the pair of handle assemblies 34 is illustrated disassembled demonstrating that the pair of handle assemblies 34 are each provided with a first unitarily formed handle portion 48 and a second handle portion 50, each of which are tubular and made from steel, or any suitable material, such as wood, fiberglass, or the like.

FIG. 4 illustrates the first handle portion 48 in greater detail. The first handle portion 48 has a distal end 52, an intermediate region 54, and a proximal end 56. The proximal end 56 is provided with a cross-section that is reduced relative to a cross-section of the intermediate region 54. The proximal end 56 is also provided with a collar 58 (FIGS. 8 and 9) that minimizes contact between the intermediate region 54 of the first handle portion 48 and the second handle portion 50.

With continued reference to FIG. 4, the proximal end 56 of the first handle portion 48 is swaged to reduce the cross-section. The swaged portion 60 is provided with an overall perimeter sized to fit within a cross-section of the second handle portion 50. The swaged portion 60 is provided with at least one aperture 64 sized to receive a fastener 66 and align with an aperture of the second handle portion 50.

An end view of the swaged portion 60 is shown in FIG. 5 illustrating that the proximal end portion 56 is not uniform with the rest of the first handle portion 48. Instead, the swaged portion 60 is provided with four corners 61 that are offset within the four corners of the intermediate region 54. In order to reduce the overall profile, four recessed side walls 62 are provided within the overall perimeter of the four corners 61, with angled portions 63 connecting the corners 61 and the sidewalls 62. Referring again to FIG. 4, the first handle portion 48 includes a transitional region 65 between the intermediate region 54 and the proximal end 56. The transitional region 65 is tapered from the larger perimeter of the intermediate region 54 to the reduced cross-section of the swaged proximal end 56.

The second handle portion 50, illustrated in FIG. 6, is provided with a distal end 70 and a proximal end 72. The proximal end 72 is provided with a square cross-section, illustrated in FIG. 7, that is sized to receive the swaged portion 60 of the first handle portion 48 in order to assemble the second handle portion 50 to the first handle portion 48. The proximal end 72 of the second handle portion 50 is provided with at least one aperture 68. The aperture 68 aligns with the aperture 64 of the first handle portion 48. Additionally, a grip region 73 is provided to the distal end 70 of the second handle portion 50.

FIGS. 8-10 illustrate the collar 58 of the first handle portion 48 in more detail. The collar 58 is slid onto the proximal end 56 of the first handle portion 48 adjacent to the intermediate region 54. The collar 58 may be attached by an adhesive. The collar 58 is provided with an angled through aperture 76 with four internal corners 78. The angled through aperture 76 is sized to receive the swaged cross-section 60 of the proximal end 56 of the first handle portion 48. The interior of the collar 58 is provided with a ridged lining 80 sized to match the shape of the recessed side walls 62 of the swaged portion 60 of the first handle portion 48. The angled through aperture 76 may align with the tapered transitional region 65 of the first handle portion 48.

The collar 58 of FIGS. 8-10 includes four sides to surround the proximal end 56 of the first handle portion 48. Referring now to FIG. 11, an alternate collar 74 is illustrated with three sides and an angled through slot 75, with two corners 77, and three projections 79 to engage the offset sidewalls 62 of the proximal end 56 of the first handle portion 48.

FIGS. 12 and 13 illustrate a grip 81 that is attached by an adhesive to the grip region 73 of the distal end 70 of the second handle portion 50. The grip 81 has a first, open end 82 and a second, closed end 84. The second end 84 has a smaller cross-section than the first end 82. The first end 82 is provided with a square cross-section which allows the grip 81 to fit over a square cross-section of the second handle portion 50.

FIG. 14 is an axial end view of the grip region 73 of the second handle portion 50. The grip region 73 is also swaged to reduce the cross-section, and to form a round overall profile for receipt in the closed end 84 of the grip 81. The cross-section is reduced by overlapping surfaces 86 that are oriented within the round perimeter.

FIGS. 15-18 illustrate the pair of handle assemblies 34 partially packaged. The pair of handle assemblies 34 may be packaged in one box. Each combination of the first handle portion 48 and the second handle portion 50 may be connected by a banding material 88. The first handle portion 48 and the second handle portion 50 are placed together so that the swaged portion 60 of the first handle portion 48 is located opposite to the grip region 73 of the second handle portion 50. In other words, the swaged recessed portion 60 of the first handle portion 48 is located next to the square cross-section of the second handle portion 50. This also indicates that an end portion 68 of the distal end 52 of the first handle portion 48 is located next to the end portion of the grip 81 of the second handle portion 50, as shown in greater detail in FIG. 18. Additionally, when the first handle portion 48 and the second handle portion 50 are assembled, the assembled handle pieces do not exceed thirty-two inches in overall length to minimize an overall length of the packaging.

By packaging the pair of handle assemblies 34 with the first handle portion 48 and the second handle portion 50 aligned lengthwise, the wheelbarrow assembly 30 is sufficiently compact to be packaged into a single box. A first box 92 is illustrated in phantom in FIGS. 19-22 to house the disassembled wheelbarrow assembly 30. The first box 92 is sized to receive the wheelbarrow tray 32 and has an approximate length of forty centimeters and an approximate width of twenty-seven centimeters, according to an example. The wheelbarrow tray 32 is sized to receive a second box 94, which is provided with a hardware kit and additional assembly pieces including the brackets 38, 40, 41, the pair of legs 42, the cross-member 46, the wheel 36, the axle 45, fasteners and the like. The pair of handle assemblies 34 are placed lengthwise in a third box 96, which allows them to be situated next to the wheelbarrow tray 32 inside the first box 92, while contained and separated from the tray 32 and the second box 94.

FIGS. 23-26 illustrate the third box 96, which holds the pair of handle assemblies 34. The distal end 52 of the first handle portion 48 is placed on top of the proximal end 72 of the second handle portion 50. Additionally, the handle assemblies 34 are stacked on top of one another. This compactness reduces the width of the third box 96 so that the third box 96 can fit within the remaining space of the first box 92. FIG. 26 shows the handle assemblies 34 stacked on top of one another from the side of the third box 96. An extended region of the third box 96 includes a tapered region 98 (FIGS. 19, 22 and 26). As illustrated in FIG. 22, the tapered region 98 assists in aligning the third box 96 within the first box 92 along a tapered side of the tray 32.

FIG. 27 illustrates the packaging of the wheelbarrow assembly 30 according to another embodiment. The wheelbarrow tray 32 is housed within a first box 100. The second box 94 is placed within the tray 32. The handle assemblies 34 are each oriented at an opposed later side of the tray 32 within the first box 100.

While various embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
