Claims21
A system for attaching a plastic wheelbarrow tub to a wheelbarrow frame comprising:
- a wheelbarrow tub comprising a bolt receiver, the bolt receiver comprising:
- a receiver head comprising:
- a receiver head width;
- a receiver head length;
- a receiver head depth;
- and
- a receiver bearing surface;
- and
- a receiver shaft comprising a receiver shaft diameter and a receiver shaft depth;
- a wheelbarrow frame;
- a bolt comprising:
- a bolt head comprising:
- a head surface;
- a head width, the bolt head width being less than the receiver head width;
- a head length, the bolt head length being less than the receiver head length;
- a head depth, the bolt head depth being less than the receiver head depth;
- and
- a head bearing surface;
- and
- a bolt shank comprising:
- a bolt shank diameter;
- and a bolt shank depth;
- and
- a nut configured to screw onto the bolt shank.
A method for attaching a plastic wheelbarrow tub to a wheelbarrow frame comprising:
- inserting a bolt through a plastic wheelbarrow tub bolt receiver and the frame, the bolt receiver comprising:
- a receiver head comprising:
- a receiver head width;
- a receiver head length;
- a receiver head depth;
- and
- a receiver bearing surface;
- a receiver shaft comprising a receiver shaft diameter and a receiver shaft depth;
- and
- a nub;
- the bolt comprising:
- a bolt head comprising:
- a head surface;
- a head width, the bolt head width being less than the receiver head width;
- a head length, the bolt head length being less than the receiver head length;
- a head depth, the bolt head depth being less than the receiver head depth;
- and
- a head bearing surface;
- and
- a bolt shank comprising:
- a bolt shank diameter;
- and
- a bolt shank depth;
- wherein the head bearing surface rests against the receiver bearing surface;
- wherein the bolt head cannot rotate more than 90 degrees;
- wherein the nub prevents the bolt from dislodging from the bolt receiver by gravity;
- and
- securing the plastic wheelbarrow tub to a wheelbarrow frame by screwing a nut to the bolt shank.
A system for attaching a wheelbarrow tub to a wheelbarrow chassis comprising:
- a wheelbarrow tub comprising a bolt receiver, the bolt receiver comprising:
- a receiver head comprising a polygonal head shape;
- a receiver head depth;
- a receiver head bearing surface;
- and
- a receiver shaft comprising a receiver shaft diameter and a receiver shaft depth;
- a chassis;
- a bolt comprising:
- a bolt head comprising:
- a head surface;
- a polygonal shape the same as the bolt receiver head polygonal shape;
- a head depth, the bolt head depth being less than the receiver head depth;
- and
- a head bearing surface wherein when the bolt head bearing surface is in contact with the bolt receiver head bearing surface the bolt head cannot rotate;
- and
- a bolt shank comprising:
- a bolt shank diameter;
- and a bolt shank depth;
- and
- a nut configured to screw onto the bolt shank.
A system for attaching a plastic wheelbarrow tub to a wheelbarrow frame comprising:
- a wheelbarrow tub comprising a bolt receiver bore having a bolt receiver wall defining a bolt receiver bore diameter;
- a wheelbarrow frame;
- a bolt comprising a bolt shank;
- and
- a nut configured to screw onto the bolt shank;
- wherein the bolt receiver bore comprises a nub that extends from the bolt receiver wall into the bolt receiver bore to provide resistance to the bolt shank sliding therein.
