20080216364 | Isokinetic snow displacing device - A handrail article containing integral nodes continuously spaced along the axis of the rail at approximate hand spacing to reduce muscle torque strain and fatigue (Isokinetics) resulting from strength applied to overcome sliding of hand grip while sustaining balance during travel on stairways. A non-obvious application of the article is to mobile hand railings as may be found on boats, public transportation, ladders and physical rehabilitation equipment. | 09-11-2008 |
20090139115 | HINGE APPARATUS - Various exemplary embodiments are provided of hinge apparatus, which may be used, for example, to hingedly connect upper and lower frame members of a device or tool. In one embodiment of a hinge apparatus, first and second linking members each include a base portion, sidewalls, and flange portions. The flange portions define sets of openings configured to receive a portion of a first connector, for selectively adjusting the angular orientation of the upper frame member relative to the lower frame member in an open, ready-for-use configuration. The linking members include connector openings configured to receive a portion of a second connector. When the first connector is not engaged with any set of openings, the upper frame member is pivotably movable relative to the lower frame member about the second connector to a closed, collapsed configuration in which the upper frame member is alongside the lower frame member. | 06-04-2009 |
20090139116 | WHEEL ASSEMBLIES - Various exemplary embodiments are provided of wheel assemblies and tires. In one exemplary embodiment, a wheel assembly generally includes first and second wheel pieces attachable to each other. The first and second wheel pieces may include respective first and second rim portions. Each of the first and second rim portions may include an arced portion that defines only a portion of a circumference of a rim, such that the arced portions collectively define the circumference of the rim when the first and second wheel pieces are attached. The first and second wheel pieces may be slidably engagable in a first axial direction that is substantially parallel to a rotational axis of the wheel assembly. The first and second wheel pieces may be slidably disengagable in a second axial direction that is generally opposite the first axial direction. | 06-04-2009 |
20090320331 | Snow shovel with spring loaded shovel head - The manually powered wheeled-levered shovel/launcher device for the purpose of snow removal, which has a handle, and shovel shaft pivoted to the handle at one end and a snow shovel head at the other end of the shovel shaft. A collapsible foldable wheel assembly acts as a fulcrum is attached to the device for easy handling a snow load. The shovel head is able to tilt downward against a spring-loaded mechanism for the purpose of altering the launch direction from upward direction due to centrifugal force around the wheel resting on the ground to forward direction when a sudden force downward is applied on the handle. | 12-31-2009 |
20100192423 | WHEELED SHOVELS - Various exemplary embodiments are provided of wheeled shovels. In one exemplary embodiment, a wheeled shovel generally includes a wheel assembly having an axle and a wheel. The wheeled shovel also includes a frame having an upper portion and a lower portion. The frame may be disposed relative to the axle such that the axle is operable as a fulcrum about which the frame may pivot. A handle may be disposed at about the upper portion of the frame. A shovel blade may be disposed at about the lower portion of the frame. The wheel assembly, frame, handle, and shovel blade may be cooperatively configured so as to enable the wheeled shovel to throw a load of material generally upwardly and forwardly away from the shovel blade in response to a sufficient force applied to the handle for pivoting the frame relative to the axle with a recoil generated through the fulcrum at the axle. | 08-05-2010 |
20110296718 | SNOW REMOVAL TOOL WITH CURVED SCOOP - A tool for manually moving snow and other loads includes a curved scoop having a leading edge and a trailing edge and a frame with handles attached to the curved scoop. The tool is balanced approximately midway between the leading edge and trailing edge when the scoop is loaded to facilitate adjustment of depth of cut and unloading. The scoop may also be temporarily deformed in response to manual application of torsional force via the handles in order to help accommodate unbalanced loads. A rope or cable can be connected to the handles. Wheels may be attached to the frame to facilitate movement over dry ground. Various removable edge members disposed on the leading edge of the scoop may be used depending on the material being loaded. Further, side panels attached to the frame may be used to enhance load capacity. | 12-08-2011 |
20140338231 | METAL SHOVEL BLADE - A snow shovel blade is provided. The snow shovel blade is a stamped metal body with a generally planar portion, a curved portion, and two opposed lateral, depending sidewalls. The sidewalls are supporting sidewalls. | 11-20-2014 |
20150089846 | WHEELED SCOOPER - A wheeled scooper is provided. The wheeled scooper reduces the time and effort needed in collecting, transporting and dumping materials. The scooper provides an elongated handle that may be transversely and forwardly pivotably connected to a collector member. The collector member may provide a front opening to a collection space defined by a front edge. The scooper may provide a set of wheels rotatably mounted near a lower rear portion of the collector member so that a user can control the elongated handle to steer the scooper over a supporting surface and easily scoop, transport and dump material into its collection space by means of the positionable front edge. | 04-02-2015 |
