Collapsible wheelbarrow and associated method
View Patent ↗An improved wheelbarrow includes a pair of legs that are each configured as four-bar linkages and are collapsible. The wheelbarrow includes a frame assembly, a wheel, a tray, and a pair of handles. The frame assembly can be assembled by the manufacturer. The wheelbarrow can then be assembled by the retailer or the consumer by simply attaching the wheel, the tray, and the handles to the frame assembly.
1. A kit from which a wheelbarrow can be assembled, the kit comprising:
a frame subassembly including a frame, an axle apparatus, at least a first leg, and at least a first tray brace connected together as an assembled unit, the at least a first tray brace being pivotably mounted to the frame subassembly;
a wheel mountable to the frame subassembly;
a tray mountable to the frame subassembly;
at least a first handle mountable to the frame subassembly;
the tray is mountable to the frame and to the at least first tray brace;
the at least first tray brace is pivotably mountable to the axle apparatus;
the axle apparatus includes (i) a pair of end members each having a hub portion, a planar flange mounting portion connectable to the frame and a protruding portion; (ii) a pair of spacers each including a central bore; and (iii) an axle; and
a pair of tray braces, each tray brace including a mounting hole disposed on one end thereof, the braces each being interposable between the spacer and the planar flange mounting portion, the protruding portion extendable through the mounting hole and into the control bore, with the axle extendable through each pair of the hub portions, the mounting holes and the central bores.
2. The kit of claim 1 , wherein
each tray brace is fixedly mountable to the tray.
3. A method of assembling a wheelbarrow from a kit, the kit having a frame subassembly, a tray, a wheel, and a handle, the frame subassembly having a frame, an axle apparatus, and at least a first leg, connected together as an assembled unit, the axle apparatus having (i) a pair of end members each having a hub portion, a planar flange mounting portion connectable to the frame and a protruding portion; (ii) a pair of spacers each including a central bore; and (iii) an axle, the method comprising:
mounting the tray to the frame subassembly;
mounting the wheel to the frame subassembly;
mounting the handle to the frame subassembly;
providing at least a first tray brace, the at least a first tray brace including a mounting hole disposed on one end thereof, the brace each being interposable between the spacer and the planar flange mounting portion, the protruding portion extendable through the mounting hole and into the control bore, with the axle extendable through each pair of the hub portions, the mounting hole and the central bores, the first tray brace being pivotably mounted to the frame subassembly;
pivoting the at least first tray brace into alignment with the tray; and
affixing the at least first tray brace to the tray.
4. The method as set forth in claim 3 , in which the step of mounting a wheel to the frame subassembly includes the steps of aligning the wheel with an axle bracket and receiving an axle through the wheel and through the axle bracket.
5. The method as set forth in claim 4 , in which the step of mounting a wheel to the frame subassembly further includes the step of removing an axle from the axle bracket.
