Abstract
Abstract A dolly characterized by a fully maneuverable, substantially planar structure and body having no handles or lateral protuberances to interfere with passage through doorways, the body having a non-marring, substantially planar upper surface and a short protrusion that is substantially normal to the upper surface for receiving the edge of an article to be tilted thereonto. The body, or a portion thereof, is tiltable to enable engaging the vertical protrusion beneath one edge of the article to be moved. The dolly is lightweight and readily carried by a single mover. Also disclosed is a preferred method of forming the non-marring surface of the body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
342 words
A dolly for moving articles with unsupported panels intermediate their corners, comprising: a. a low profile substantially planar structure; b. a plurality of at least three wheels connected with said dolly so as to form a stable dolly, at least one of said wheels being universally swivelable for full and easy manuverability of said dolly: said wheels carrying said low profile structure such that its height above the plane of the bottom of the wheels is less than its lateral and longitudinal dimensions; c. a body comprising a plurality of portions carried by said structure and defining a non-marring, substantially planar upper surface, at least one of said portions being a fixed portion that is fixedly attached to said structure and at least one other of said portions being a pivotal portion carrying a load bearing ledge at one edge thereof; said pivotal portion being mounted on said structure at the side thereof adjacent said one edge for pivotal movement about a pivot axis that is disposed exteriorly of a straight line between adjacent wheels and that has a moment arm with respect thereto such that said dolly will tilt upwardly to meet an article to be moved as it is upended thereon: said load bearing ledge being disposed exteriorly of said straight line connecting the two wheels on both sides thereof such that said short protrusion means can engage said edge of said article without said wheels encountering said article; said pivotal portion carrying said load bearing ledge being pivotal for being tilted to emplace said load bearing ledge beneath an end of and engaging an edge of said article to be moved, for preventing said dolly from rolling from beneath said article and to receive said article when it is upended onto said dolly, such that said article can be upended and loaded onto said dolly by a single mover and fully manuvered by said single mover for passage through doorways and the like without requiring any supplemental holding device and without requiring assistance from an additional worker or mover.

A dolly for moving articles with unsupported panels intermediate their corners, comprising: a. a low profile substantially planar structure; b. a plurality of at least three wheels connected with said dolly so as to form a stable dolly, at least one of said wheels being universally swivelable for full and easy manuverability of said dolly: said wheels carrying said low profile structure such that its height above the plane of the bottom of the wheels is less than its lateral and longitudinal dimensions; c. a body comprising a plurality of portions carried by said structure and defining a non-marring, substantially planar upper surface, at least one of said portions being a fixed portion that is fixedly attached to said structure and at least one other of said portions being a pivotal portion carrying a load bearing ledge at one edge thereof; said pivotal portion being mounted on said structure at the side thereof adjacent said one edge for pivotal movement about a pivot axis that is disposed exteriorly of a straight line between adjacent wheels and that has a moment arm with respect thereto such that said dolly will tilt upwardly to meet an article to be moved as it is upended thereon: said load bearing ledge being disposed exteriorly of said straight line connecting the two wheels on both sides thereof such that said short protrusion means can engage said edge of said article without said wheels encountering said article; said pivotal portion carrying said load bearing ledge being pivotal for being tilted to emplace said load bearing ledge beneath an end of and engaging an edge of said article to be moved, for preventing said dolly from rolling from beneath said article and to receive said article when it is upended onto said dolly, such that said article can be upended and loaded onto said dolly by a single mover and fully manuvered by said single mover for passage through doorways and the like without requiring any supplemental holding device and without requiring assistance from an additional worker or mover.
Claim 3
Dependent Claim
14 words
The dolly of claim 1 wherein there are a plurality of said fixed portions.
Claim 4
Dependent Claim
26 words
The dolly of claim 1 wherein said body comprises three portions, two end portions that are fixedly attached to said structure and an intermediate pivotal portion.
Claim 5
Dependent Claim
23 words
The dolly of claim 1 wherein four wheels are connected with said structure and at least two of said wheels are universally swivelable.

Claim 7
Dependent Claim
268 words
A dolly for moving articles with unsupported panels intermediate their corners, comprising: a. a low profile substantially flat framework structure that is lightweight, and is thin relative to its lateral and longitudinal dimensions; b. a plurality of at least three wheels that are pivotally connected with said structure, each of said wheels being universally swivelable to attain any azimuth in response to a force imparted to said structure; said wheels carrying said structure with a low profile such that its height above the plane of the bottom of the wheels is less than its lateral and longitudinal dimensions; and c. a body comprising a pair of fixed end portions and at least one pivotal portion intermediate said end portions; said body being carried by said structure and defining a non-marring, substantially planar upper surface, said pivotal portion of said body having a load bearing ledge at one edge that is substantially normal to its planar upper surface for engaging an edge of an article to be moved and preventing said dolly from rolling from beneath said article; said pivotal portion of said body being mounted on said structure for pivotal movement about a pivot axis that is disposed exteriorly of a straight line between adjacent wheels and having a moment arm with respect thereto such that said dolly will tilt upwardly to meet said article as it is upended thereon; said load bearing ledge being disposed exteriorly of said straight line between said two wheels on both sides thereof such that said short protrusion means can engage said edge of said article without said wheels encountering said article.
