  • the term "dolly” is a small wheeled trolley for carrying a load, the trolley usually being non motorized.
  • dollies are widely used in places ranging from the home to factories to do it yourself construction material outlets. In the latter instance, the material transported by the dolly would include goods such as lumber, panels, doors, beams, etc.
  • dollies in large box construction retail outlets generally range from a simple flat floor to those having dividers to receive different materials. Generally, they operate on four wheels and are of a substantial size.
  • a wheel assembly comprising a frame, the frame having wheel mounting means thereon, a wheel mounted on the wheel mounting means, and a first member extending diagonally upwardly and outwardly from a bottom portion of the frame when the wheel is in a vertical position.
  • a dolly comprising first and second wheel assemblies, each wheel assembly comprising, a frame, the frame having wheel mounting means thereon, a wheel mounted on the wheel mounting means, and a member extending diagonally upwardly and outwardly from a bottom portion of the frame when the wheel is in a vertical position, each of the members being pivotably connected together.
  • a wheel assembly of the present invention is preferably utilized in pairs to form a dolly like structure wherein the wheel assemblies are pivotably connected together.
  • the wheel assemblies may be used individually as will be shown in the illustrated embodiments of the invention.
  • the wheel assembly may be formed of any suitable material and the material chosen will reflect what the final characteristics of the wheel assembly are. Thus, for some loads, a metallic material may be appropriate while for lighter loads, one may utilize various plastic materials.
  • the wheel is characterized by preferably having at least a portion thereof formed in an arcuate configuration. This provides a better running surface when the wheel essentially runs on its side.
  • each wheel assembly utilizes a member which extends diagonally upwardly from a lower portion of the frame when the wheel is oriented in a vertical direction.
  • This member is utilized to grip the cargo being carried as will be discussed in greater detail hereinbelow.
  • a single member may, in some embodiments, be utilized particularly when the member is sized to be sufficiently large.
  • wheel assemblies When the wheel assemblies are used to form a dolly, they are pivotably connected together such that they may securely and rapidly retain a load mounted thereon.
  • the wheel assemblies may be utilized in a variety of manners for transporting different types of loads.
  • two wheel assemblies are utilized although more could be employed depending upon the nature of the load - i.e. the weight and length thereof.
  • Figure 1 is an end view of an assembled dolly according to a first aspect of the present invention
  • Figure 2 is a perspective view of an assembled dolly showing a portion of a handle connected thereto;
  • Figure 3 is a perspective view of a wheel assembly forming a portion of the dolly
  • Figure 4 is a further perspective view of a wheel assembly
  • Figure 5 is a end elevational view of wheel assembly
  • Figure 6 is a perspective of an assembled dolly having a handle portion in place for carrying the same;
  • Figure 7 is an end view of a dolly carrying a load;
  • Figure 8 is a side elevational view of a variation of a wheel assembly according to the present invention.
  • Figure 9 is a perspective view of a pair of wheel assemblies utilized to render a pallet mobile
  • Figure 10 is a perspective view of four wheel assemblies utilized to render a container mobile
  • Figure 11 is a detailed view of a distal end of one embodiment of a member according to the present invention.
  • Figure 12 is an end view illustrating the transport of an I beam utilizing the wheel assembly of the present invention
  • Figure 13 is an end view illustrating the use of two wheel assemblies to transport a T beam
  • Figure 14 is a side elevational view illustrating transport of sheet material utilizing the dolly of the present invention.
  • Figure 15 is an end view of a pair of wheel assemblies transporting a swivel table
  • Figure 16 is a sectional view thereof.
  • Figure 17 is a perspective view of a modified wheel utilized with the wheel assemblies of the present invention.
  • first wheel assembly 12 and a second wheel assembly 12' as may be best seen in Figures 3, 4 and 5. Since first wheel assembly 12 and second wheel assembly 12' are essentially identical, only one of the wheel assemblies will be described in detail. Where the second wheel assembly is described, similar reference numerals utilizing a prime are employed for components similar to first wheel assembly 12.
  • Wheel assembly 12 includes a frame portion 16 on which is mounted a wheel 18 and which wheel is retained in place by means of retainers 20.
  • the mounting of wheel 18 to frame 16 may be done in a conventional manner and will include at least a first set of bearings although two sets of bearings may be utilized where the dolly is intended to carry heavy loads.
  • wheel 18 has a running surface generally designated by reference numeral 23 and which running surface 23 has a flat portion 25 similar to a conventional wheel or tire and an arcuate portion 27.
  • Frame 16 in the illustrated embodiment, comprises a plate like member and has a first side wall 24 extending outwardly therefrom.
  • Side wall 24 only extends a portion of the height of frame 16 and includes a protective flange 26 extending outwardly towards the outer side while a recess 28 is formed at the bottom thereof for reasons which will become apparent hereinbelow.
  • a second side wall 30 which likewise has a flange 32 extending outwardly and a recess 34 formed at a bottom end thereof.
  • bumper elements 36, 38 and 40 On the interior of frame 16 and at the upper end thereof, there are provided a plurality of bumper elements 36, 38 and 40, again for reasons which will be discussed in greater detail hereinbelow. At the other side wall, there are likewise provided bumpers 42, 44 and 46.
  • an arcuate recess 48 to accommodate a handle member 50 extending thereacross.
  • a member 52 extends diagonally upwardly from a position near the bottom of frame 16. Member 52 has, at distal end 54, a bumper structure 56. An elongated slot 58 is formed in member 52 for reasons which will become apparent hereinbelow.
  • a second member 60 again extends diagonally upwardly.
  • a distal end 62 is provided with a bumper 54 while a elongated slot 66 extends along a portion of a length of member 60.
  • a second handle structure 68 is provided as may be seen in Figures 2 and 6.
  • Handle 68 includes a pair of legs 72 having projections (not shown) which are designed to fit within recesses 28 and 34.
  • An upper portion 74 of handle 68 has a plurality of elongated apertures 76 formed therein which may function to permit the hands of a user to readily grip handle 68 at a convenient location.
  • first wheel assembly 12 and second wheel assembly 12' function as a dolly
  • a rod 78 extends through elongated slots 58, 58', 66 and 66'.
  • dolly 10 may be utilized to carry a load 80.
  • load 80 is placed such that it is supported by members 52, 52', 60 and 60'. This causes the wheel assemblies to pivot outwardly at the lower portion thereof and inwardly at the upper portion thereof such that bumpers 36, 38, 40, 42, 44 and 46 along with the bumpers on second wheel assembly 12' grip the load 80.
  • the load 80 is reasonably well balanced, one end of the load may be held and the load moved by the user.
  • the dolly When the dolly is in an operative position, it will be noted that the wheels 18, 18' run on the arcuate portion 27 of running surface 23.
  • a pair of outrigger legs 82 and 86 having stabilizing wheels 84 and 88 respectively attached thereto may be provided.
  • first wheel assembly 12 and second wheel assembly 12' may be placed on a pallet 92 to enable transport of the pallet.
  • a similar arrangement is illustrated in Figure 10 wherein there are provided four wheel assemblies to move a container 94.
  • a plurality of spikes 96 may be mounted on distal end of members 52 and 60 to provide for more secure gripping of a load which is wood or similar pierceable material.
