Dolly assembly
View Patent ↗A dolly assembly includes a dolly having an upper surface and a lower surface, and an aperture passing into at least the lower surface, and a ramp having an extension that extends beyond an edge of the ramp, the extension having at least one upward-facing ramp nub that, when positioned in the aperture, the ramp and the dolly are locked together as a unit.
1. A dolly assembly, comprising:
a dolly having an upper surface and a lower surface, and an aperture passing into at least the lower surface; and
a ramp having an extension that extends beyond an edge of the ramp, the extension having at least one upward-facing ramp nub that, when positioned in the aperture, the ramp and the dolly are locked together as a first unit.
2. The dolly assembly of claim 1 , wherein the aperture passes through both the lower surface and the upper surface of the dolly.
3. The dolly assembly of claim 2 , further comprising a rung passing through the aperture and positioned below the upper surface, the rung configured to receive a harness for attaching an object to the upper surface of the dolly.
4. The dolly assembly of claim 3 , wherein the at least one upward-facing ramp nub includes two upward-facing ramp nubs that are positioned laterally with respect to one another, each of the two upward-facing ramp nubs extending to either side of the rung.
5. The dolly assembly of claim 1 , the ramp further comprising an upper angled surface that extends from approximately a lower location corresponding approximately with a base surface on which the ramp is positioned, to an upper location corresponding approximately with the upper surface of the dolly.
6. The dolly assembly of claim 1 , the dolly further comprising at least one depression in the upper surface that receives a wheel to be positioned on the upper surface.
7. The dolly assembly of claim 1 , further comprising a skid-converter that includes at least one upward-facing skid-converter nub that, when the dolly is positioned on the skid converter, the at least one upward-facing skid-converter nub is positioned in the aperture and the dolly rests upon one or more upper surfaces of the skid-converter.
8. The dolly assembly of claim 7 , wherein the at least one upward-facing skid-converter nub includes two upward skid-converter nubs, each of the two upward-facing skid-converter nubs extending into the aperture.
9. The dolly assembly of claim 7 , wherein the at least one upward-facing skid-converter nub includes a skid-converter pin hole passing therethrough, and the dolly includes a dolly pin hole proximate the aperture, such that when the dolly is positioned on the skid-converter the skid-converter pin hole and the dolly pin hole are aligned with one another, and when a pin is passed into the aligned holes, the skid-converter and the dolly are locked together as a second unit.
10. The dolly assembly of claim 1 , wherein the dolly includes a plurality of castors for rolling the dolly on a base surface.
11. A method of fabricating a dolly assembly, comprising:
providing a dolly having an upper surface and a lower surface, and an aperture passing through at least the lower surface;
providing a ramp for the dolly, the ramp having an extension that extends beyond an edge of the ramp and at least one upward-facing ramp nub; and
locking the ramp to the dolly as a first unit by positioning the at least one nub in the aperture.
12. The method of claim 11 , wherein providing the dolly comprises the aperture passing through both the lower surface and the upper surface of the dolly.
13. The method of claim 12 , further comprising passing a rung through the aperture that is positioned below the upper surface, the rung configured to receive a harness for attaching an object to the upper surface of the dolly.
14. The method of claim 13 , wherein providing the ramp includes providing the at least one upward-facing ramp nub to include two upward-facing ramp nubs that are positioned laterally with respect to one another, each of the two upward-facing ramp nubs extending to either side of the rung.
15. The method of claim 11 , wherein providing the ramp further comprises providing an upper angled surface that extends from approximately a lower location corresponding approximately with a base surface on which the ramp is positioned, to an upper location corresponding approximately with the upper surface of the dolly.
16. The method of claim 11 , further comprising providing at least one depression in the upper surface of the dolly that receives a wheel to be positioned on the upper surface.
17. The method of claim 11 , further comprising:
providing a skid-converter having at least one upward-facing skid-converter nub
positioning the on the skid converter such that the at least one upward-facing skid-converter nub is positioned in the aperture and the dolly rests upon one or more upper surfaces of the skid-converter.
18. The method of claim 17 , wherein providing the ramp includes providing the at least one upward-facing skid-converter nub to include two upward skid-converter nubs, each of the two upward-facing skid-converter nubs extending into the aperture.
19. The method of claim 17 , further comprising:
providing the skid-converter includes providing the at least one upward-facing skid-converter nub having a skid-converter pin hole passing therethrough;
providing the dolly includes providing a dolly pin hole proximate the aperture, such that when the dolly is positioned on the skid-converter the skid-converter pin hole and the dolly pin hole are aligned with one another; and
passing a pin into the aligned holes, locking the skid-converter and the dolly together as a second unit.
20. The method of claim 11 , wherein providing the dolly includes providing a plurality of castors for rolling the dolly on a base surface.
