Abstract
A self-loading dolly apparatus. Each of a pair of support bars has a saddle bracket and an inside wheel assembly rigidly affixed with the support bar and offset from the vertical axis. A lift bar is secured to the saddle brackets, then raised so that an outside pair of wheel assemblies can be positioned adjacent the respective saddle bracket. The outside wheel assemblies are secured when the lift bar is raised, whereupon the inside wheel assemblies and the saddle brackets realign with the vertical axis and the support bars are angled upward.
Claims20
A dolly apparatus, comprising:
- a pair of coupling brackets disposed in a spaced apart parallel arrangement in a horizontal plane;
- a lift bar removably coupled to each of the pair of coupling brackets;
- a pair of support bars each having an inside end and an outside end, each support bar rigidly coupled at its outside end to a respective one of the pair of coupling brackets at a first acute angle relative to the lift bar such that the support bars are angled inward toward each other;
- a first pair of wheel assemblies, each of the first pair of wheel assemblies coupled to the inside end of a respective one of the pair of support bars at a second acute angle such that the wheel assemblies are offset from a vertical axis;
- and
- a second pair of wheel assemblies, each of the second pair of wheel assemblies is removably coupled to a respective one of the pair of coupling brackets after the lift bar is raised in order to position each of the second pair of wheel assemblies adjacent the respective coupling bracket, then the lift bar is lowered and the second pair of wheel assemblies secured to respective brackets;
- wherein positioning and securing the second pair of wheel assemblies causes the first pair of wheel assemblies to level out and align with the vertical axis and the first pair of support bars to angle upward at the second acute angle.

A dolly apparatus, comprising:
- first and second support bars, each support bar having a distal end and a proximal end, each support bar having an upward angled portion at its distal end;
- first and second wheel assemblies, each of the first and second wheel assemblies having a top plate rigidly affixed to the angled portion of a respective one of the first and second support bars such that the top plate is disposed at a first angle upward relative to the support bars;
- first and second saddle brackets disposed in a spaced apart parallel arrangement, each of the saddle brackets coupled to the proximal end of a respective one of the first and second support bars such that the saddle bracket is offset from a vertical axis at the first angle;
- third and fourth wheel assemblies each removably coupled to a respective one of the first and second saddle brackets;
- and
- a lift bar removably coupled to the first and second saddle brackets;
- wherein the lift bar is raised to place the third and fourth wheel assemblies adjacent respective saddle brackets, then lowered to secure the third and fourth wheel assemblies to the saddle brackets, which causes the first and second wheel assemblies to level out and align with the vertical axis and the first pair of support bars to angle upward at the first angle.

A dolly apparatus, comprising:
- a pair of support bars each having an inside end and an outside end,
- a pair of saddle brackets disposed in a spaced apart parallel arrangement, each support bar rigidly coupled at its outside end to a respective one of the saddle brackets such that the saddle bracket is offset from a vertical axis by a first angle;
- a first pair of wheel assemblies, each of the first pair of wheel assemblies coupled to the inside end of a respective one of the pair of support bars such that the wheel assemblies are offset from the vertical axis by the first angle;
- a lift bar removably coupled to the saddle brackets;
- a second pair of wheel assemblies, each of the second pair of wheel assemblies is positioned adjacent a respective one of the saddle brackets after raising the lift bar, then secured to the saddle bracket when the lift bar is lowered, wherein the first pair of wheel assemblies and the pair of saddle brackets align with the vertical axis and the outside ends of respective ones of the pair of support bars are angled upward at the first angle.
