Patent number: 11623481Abstract: A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.Type: GrantFiled: May 18, 2020Date of Patent: April 11, 2023Inventor: Jacqueline Coffin

Patent number: 10994571Abstract: A wheel, typically for use in conjunction with an agricultural irrigation system such as a pivot or wheel line. The wheel has a disc shaped body having a hub to attach to an external frame. The wheel has a plurality of feet attached to the circumference of the body. The feet are generally channel shaped having two ends at either end of the channel. The feet are positioned at the circumference of the body either on the circumference or in indentations or grooves on the circumference such that the ends of the feet overhang the body. Preferably the feet have a space, opening or void between the feet to allow for the passage of snow, mud or other material.Type: GrantFiled: February 27, 2018Date of Patent: May 4, 2021Inventor: Benjamin Jensen Beck

Patent number: 8657215Abstract: A wheel apparatus includes a hub that is configured to be received by an axle of an irrigation system. The wheel apparatus also includes a rim assembly that includes a plurality of substantially flat feet that form a faceted circular arrangement. A support structure is disposed between the hub and the rim assembly to at least partially support the rim assembly. At least one of the substantially flat feet is coupled to at least one of the plurality of spoke structures. The wheel apparatus also includes at least one cleat disposed on an outside surface of at least one of the plurality of substantially flat feet to provide traction to the rim assembly.Type: GrantFiled: November 29, 2011Date of Patent: February 25, 2014Inventor: Benjamin D. Blum

Patent number: 7775610Abstract: A flotation drive wheel is provided for a self-propelled irrigation system such as a center pivot irrigation system, a linear irrigation system or a corner irrigation system. The flotation drive wheel of this invention comprises a hub portion which is directly attached to an associated gearbox of the conventional drive tower. A metal band or plate is welded to the outer periphery of the hub portion of the wheel with a plurality of pivotal flotation shoes being attached to the band or plate. The pivotal shoes include structure for preventing soil from being pushed laterally of the flotation wheel and from being pushed forwardly from the drive wheel. The flotation wheel of this invention substantially eliminates the creation of wheel ruts or tracks.Type: GrantFiled: February 21, 2008Date of Patent: August 17, 2010Inventor: Lynn W. Mettenbrink

Patent number: 6793026Abstract: A wall-climbing robot or mobility platform able to ascend and descend various horizontal and vertical surfaces having a chassis, a rotor rotatable with respect to the chassis, one or more prominences on the rotor, and means for adhering to a surface attached to the prominences. The robot is able to make a transition from horizontal travel to vertical travel. In certain embodiments, the means for adhering to a wall is a pressure sensitive adhesive. In addition, multiple rotor configurations and radio-control are used for remote operation.Type: GrantFiled: November 27, 2001Date of Patent: September 21, 2004Assignee: i Robot CorporationInventor: Thomas L. De Fazio

Patent number: 6443466Abstract: An all-terrain bicycle is comprised of a bicycle frame having a front and a rear fork to which is removably secured a front and a rear wheel. Each wheel has a circular rim which is interconnected to the hub by spokes. The rear wheel has sprockets secured to the central hub and which is interconnected to a driving sprocket by a chain or other such belt-like drive connector. Each of the rims is provided with a surface engaging support shoes assembly to provide support of the bicycle on a surface. Such bicycles are particularly useful for riding on soft and also irregular surfaces which are deformable such as sand, snow or the like.Type: GrantFiled: February 16, 2001Date of Patent: September 3, 2002Assignee: Carl-All, Inc.Inventor: Antoine Trubiano

Patent number: 6099091Abstract: A drive wheel, having a cylindrical surface positioned at a radius from the center of the drive wheel, and a plurality of suction cup members disposed in a spaced apart relationship on the cylindrical surface, useful in a pressurized pool cleaning apparatus.Type: GrantFiled: January 20, 1998Date of Patent: August 8, 2000Assignee: Letro Products, Inc.Inventor: Sanford F. Campbell

Patent number: 5839795Abstract: A variable outer diameter wheel includes a generally cylindrical pipe or drum having four equally spaced penetrating holes or receiving parts in the cylindrical wall, a diaphragm sealing member corresponding to each of the penetrating holes and fitted to the pipe support, and sliders forming a wheel peripheral face so that the sliders can smoothly slide in the penetrating holes. The sliders are pushed or activated and moved outward from the pipe in a direction so the wheel outer diameter is enlarged by compressed air supplied through a passage and a hole provided in an axle which support the wheel. Exhausting the compressed air causes the wheel outer diameter to decrease and restores the wheel to its original size. Variable outer diameter wheels permit safe operation of vehicles on frozen, snow-clad or irregular surfaced roads.Type: GrantFiled: October 24, 1996Date of Patent: November 24, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yutaka Matsuda, Kaoru Shimizu

Patent number: 5366038Abstract: A robot traveling on wall face is capable of advancing or retreating on the wall face in a stable manner with a quick change-over of its traveling direction with the help of a plurality of movable adsorption discs designed for a close contact with the wall face, and a pair of fixed adsorption rods, while commencing to be moved by drive motors. The adsorption force by these movable adsorption discs is constantly so large that no worry of dropping the robot from the wall surface is needed. The frictional resistance of each frictional surface promotes contact between the robot and the wall face. Thereby, the robot works on the wall in a safe manner, instead of human workers.Type: GrantFiled: June 24, 1993Date of Patent: November 22, 1994Assignee: Nishiguchi HidetsuguInventors: Nishiguchi Hidetsugu, Nishiguchi Kenji

Patent number: 4759638Abstract: A wheel comprises a hub 11 and a plurality of ground-engaging pads 16 disposed around and coupled to the periphery of the hub by radial studs 17. Each pad is capable of at least a limited degree of angular displacement about the axis of its stud 17 whereby the hub may turn through such angle relative to any pad currently in ground contact. A resilient stop 30 is associated with each pad to return each pad to its undisplaced position when the pad has moved out of contact with the ground. In an alternative embodiment a resilient member between the hub and the pad serves to both limit angular displacement and return the pad to its undisplaced position.Type: GrantFiled: February 25, 1987Date of Patent: July 26, 1988Inventor: Hugh R. McLaughlin
