Dump cart bolt system
A dumping cart is disclosed. The cart allows for complete dumping while maintaining four wheels on the ground and can rotate the rear set of wheels to allow the bed of the cart to be completely turned over for emptying. Also disclosed is a method of attaching an article retaining bed to a cart.
1 . A system for attaching an article retaining bed to a chassis comprising:
an article retaining bed comprising a bolt receiver, the bolt receiver comprising:
a receiver head comprising:
a receiver head width;
a receiver head length, the receiver head length being substantially equal to the receiver head width;
a receiver head depth; and
a receiver 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 head width, the bolt head width being less than the receiver head width;
a head length, the bolt head length being substantially equal to the bolt head width and 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;
wherein the bolt head width is substantially equal to the bolt head length; and
a bolt shank comprising:
a bolt shank diameter; and a bolt shank depth; and
a nut configured to screw onto the bolt shank.
2 . The system for attaching an article retaining bed to a chassis of claim 1 wherein the head bearing surface rests against the receiver bearing surface.
3 . The system for attaching an article retaining bed to a chassis of claim 2 wherein the bolt head cannot rotate.
4 . The system for attaching an article retaining bed to a chassis of claim 3 wherein the receiver shaft comprises at least one nub.
5 . The system for attaching an article retaining bed to a chassis of claim 4 wherein the nub is formed as part of the retaining bed.
6 . The system for attaching an article retaining bed to a chassis of claim 5 wherein the nub prevents the bolt from dislodging from the bolt receiver by gravity.
7 . The system for attaching an article retaining bed to a chassis of claim 6 wherein the nub is located adjacent to the receiver bearing surface.
8 . The system for attaching an article retaining bed to a chassis of claim 6 wherein the nub is located distal to the receiver bearing surface.
9 . The system for attaching an article retaining bed to a chassis of claim 8 wherein the receiver shaft comprises two nubs.
10 . The system for attaching an article retaining bed to a chassis of claim 8 wherein the receiver shaft comprises three nubs.
11 . The system for attaching an article retaining bed to a chassis of claim 1 wherein the nut is a nylon insert lock nut.
12 . A method for attaching an article retaining bed to a chassis:
inserting a bolt through an article retaining bed bolt receiver and the chassis, the bolt receiver comprising:
a receiver head comprising:
a receiver head width;
a receiver head length, the receiver head length being equal to the receiver head width;
a receiver head depth; and
a receiver bearing surface;
a receiver shaft comprising a receiver shaft diameter and a receiver shaft depth; and
at least one 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 equal to the bolt head width and 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;
wherein the bolt head width is substantially equal to the bolt head length; 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 at least a force of gravity; and
securing the chassis to the article retaining bed by screwing a nut to the bolt shank.
13 . The method of attaching an article retaining bed to a chassis of claim 12 wherein the nut is a nylon insert lock nut.
14 . The method of attaching an article retaining bed to a chassis of claim 12 wherein the bolt receiver comprises two nubs.
15 . The method of attaching an article retaining bed to a chassis of claim 12 wherein the bolt receiver comprises three nubs.
16 . The method of attaching an article retaining bed to a chassis of claim 15 wherein one of the nubs is formed as part of the retaining bed.
17 . The method of attaching an article retaining bed to a chassis of claim 12 wherein the nub prevents the bolt from dislodging from the bolt receiver by gravity.
18 . The method of attaching an article retaining bed to a chassis of claim 17 wherein the nub is located distal to the receiver bearing surface.
19 . The method of attaching an article retaining bed to a chassis of claim 17 wherein the nub is located adjacent to the receiver bearing surface.
20 . The method of attaching an article retaining bed to a chassis of claim 17 comprising a nub located distal to the receiver bearing surface and a nub located adjacent to the receiver bearing surface.
