| 280470300 | Single wheel vehicle | 36 |
| 20100320709 | Hand truck - The hand truck is configured for the carriage of large, heavy, generally cylindrical buckets of wallboard compound, paint, etc. The handlebars include one or more latch bars extending therebetween, with each latch bar having a fixed bale latch. The latch bars and bale latches are configured so that when a standard material bucket is placed on the platform when the platform is resting on the surface, the bale of the bucket will clear the bale latch when the bale is swung rearwardly toward the handlebars. However, when the truck is tilted rearwardly for transport, the bucket tilts forwardly and the bale catches on the bale latch, thereby securing the bucket on the truck. When the truck is repositioned with the platform resting on the surface, the handlebars swing toward the upper edge of the bucket to provide sufficient slack to allow the bale to be removed from the bale latch. | 12-23-2010 |
| 20110049823 | DEVICE FOR MOVING LARGE CONTAINERS - Devices and methods of using such devices to move containers are disclosed herein. A device may include a first piece with a wheel adjacent one end and a second piece attached to the first piece at a pivotal connection.

| 20120205884 | TRACTION DEVICE AND APPARATUS WITH FOLDABLE FRAME - An apparatus for traversing loose, granular material includes a frame and a rotatable traction device connected to the frame. The outer surface of the rotatable traction device includes spaced apart curvilinear or angular traction ridges and spaced apart curved or angular valleys, each valley being between a pair of adjacent traction ridges, thereby forming curved or angular shovel-like elements. Each shovel-like element has a leading curved or angular surface and a confining curved or angular surface. Rotation of the rotatable traction device results in rotation of the shovel-like elements through the loose, granular material. Each shovel-like element enfolds a portion of the loose, granular material bordering the leading curved or angular surface of the shovel-like element, and the confining curved or angular surface of the shovel-like element confines at least part of the enfolded portion of the material, thereby confining and restricting displacement of the enfolded portion of the material. | 08-16-2012 |
| 20140291949 | Device and Method to Move a Bale of Agricultural Material - A device to move material comprises a front frame comprising an axle extension, a wheel connected to the front frame via an axle connected to the axle extension, and two arms rotatably connected to the front frame via hinges, each arm rotatable about an axis that is substantially perpendicular to a length of the front frame and a length of the each arm so as to define an arm closing swinging direction and an arm opening swinging direction for the each arm. The device further comprises two handles, each handle connected to an end of each of the two arms, and a plurality of gripping extensions connected to the two handles, wherein each arm comprises at least two of the gripping extensions located at an arm closing swinging direction of the each arm. | 10-02-2014 |

| 20080246240 | Wheelbarrow stabilizer with improved load distribution - A device for stabilizing and supporting wheelbarrows which maintains the balance and increases the resistance of a system (wheelbarrow) including an angled monolithic body which is made up of two arms which define a triangular shape, whose ends have holes for the insertion of affixing means to affix to the leg of a wheelbarrow. In one embodiment, one of said arms makes up an arched area along most of its length which generates two points of support, a first point of support defined on the end of the joint affixing with the leg of the wheelbarrow and a second point of support defined in the area near where the two arms meet to define that angle. The arched area of the arm, positioned substantially horizontally and defining the two points of support, absorbs deformation, and also absorbs the load applied to the element, bringing more stability to the wheelbarrow on flat or irregular surfaces, providing a stabilizer comprised by each leg. | 10-09-2008 |

The kit has a pair of axles, a pair of wheels, and a sleeve. To form a single-wheeled wheelbarrow, an axle is inserted through a first axle bracket, through a wheel, and then through a second axle bracket. A pin is inserted through a hole at the tip of the axle. To form a double-wheeled wheeled barrow, a first axle is inserted through a first wheel and then through a first axle bracket. A second axle is inserted through a second wheel and then through a second axle bracket. A sleeve holds the ends of both the axles. Pins are utilized for locking the axles with the corresponding axle brackets or sleeve. In the single-wheeled configuration the second wheel, second axle, and sleeve can be stored on the wheelbarrow. | 08-12-2010 |
| 20110101635 | ONE-HAND OPERATION CONVERSION AND TORQUE CONTROLLER FOR WHEELBARROW HANDLES - The “ONE-HAND OPERATION CONVERSION AND TORQUE CONTROLLER FOR WHEELBARROW HANDLES” added to a wheelbarrow, on one hand, offers single hand operability and maneuverability, and on the other hand offers added benefits to dual-handed users. The wheelbarrow can easily be converted from dual to single-handed operation and then back again with this said unit. This is completed by adding a centrally mounted handle to cross support(s) which are attached to the two longitudinally extending handles of the said wheelbarrow. When the center handle is attached, one-hand operation is achieved by the load balancing capabilities of the said handle and its mounting orientation. The center handle is formed into or mounted to the cross support(s) that are mounted or formed into the existing longitudinal handles. The unit size dimensions and mounting method are arbitrary and will be made to fit the circumstances of mounting position and cross support material. The cross support(s) material and the handle material are of variable rigid form. The cross support mounts are variably rigid and can be adapted to fit the form of the said cross support(s) as well as conformed to the shape of the said wheelbarrows longitudinal handles. The cross support(s) offer the user an ergonomically padded contact area. This contact area can be used to apply a force by means of the upper thigh area when the wheelbarrow is in use under heavy load. While under heavy load a user is often subjected to high stresses by the wheelbarrow under tipping conditions and this creates a torque to reside between the users' hands/arms and the wheelbarrow handles. In order to help overcome this moment affect, the wheelbarrow cross member(s) handle conversion kit has been extended to offer increased torque and roll control. These said extensions are either in line, above, below or in some relative angle of placement to the center mounted cross support(s). | 05-05-2011 |
