Abstract
A dolly includes a first skate, a second skate, and a rod connected to the skates. The first skate is connected to a plurality of wheels and has a receiving region. The second skate is connected to a plurality of wheels and has a receiving region. The second skate includes an outer lateral surface having an aperture. The rod is connected to the first skate and the second skate via the respective receiving regions of the respective skates. The rod is configured to extend through the aperture such that a portion of the rod extends outwardly from the outer lateral surface of the second skate.
Claims22
A dolly configured to travel over an object, comprising:
- a first skate connected to a plurality of wheels, and including an underside, a leading edge, a trailing edge, and a deflecting region between the leading edge and the plurality of wheels;
- a second skate connected to a plurality of wheels, and including an underside, a leading edge, a trailing edge, and a deflecting region between the leading edge and the plurality of wheels;
- and
- at least one rod connected to the first skate and the second skate to couple the first skate with the second skate,
- wherein, the deflecting region of the first skate is configured to deflect the first skate upwardly over the object as the dolly travels forwardly and as the deflecting region is pushed against the object, such that a portion of the plurality of wheels connected to the first skate are moved upwardly,
- wherein, the deflecting region of the second skate is configured to deflect the second skate upwardly over the object as the dolly travels forwardly and as the deflecting region is pushed against the object, such that a portion of the plurality of wheels connected to the second skate are moved upwardly, and
- wherein the deflecting region of the first skate comprises a straightly-sloped profile, and wherein the deflecting region of the second skate comprises a straightly-sloped profile.
