Abstract:
A wheel assembly comprising a wheel disk and a tread member disposed around the wheel disk. The wheel disk can have a substantially conical shape when in an unloaded state, but be flexible such that it can deform under load to optimize and/or maximize contact area between the tread member and a driving surface.
Abstract:
A magnetic roller for being rotatable on a ferromagnetic surface is provided. The magnetic roller includes a roller wheel having an inner space, a magnetic array arrangement and at least one first drive mechanism. Further, the magnetic array arrangement is adapted to be swivelably disposed within the inner space of the roller wheel. The magnetic array arrangement includes a strong adhesion force side and a weak adhesion force side. Furthermore, the first drive mechanism is configured to swivelably drive the magnetic array arrangement. The first drive mechanism swivelably drive the magnetic array arrangement to direct the strong adhesion force side towards the oncoming ferromagnetic surface, and, to direct the weak adhesion force side towards the foregoing ferromagnetic surface to enable the roller wheel to move forward on the ferromagnetic surface.
Abstract:
An improved wheel is disclosed which is capable of traversing small obstacles easily without having to mount over the obstacle. The wheel design includes a wheel hub having an axis of rotation and a wheel rim coupled to the hub by a plurality of spokes. The wheel rim is formed in the shape of an annular sinusoidal wave having a plurality of alternating crests and troughs extending away from a center line by an amplitude. The wheel rim is configured such that the spokes couple to the rim at the center line at an intersection of the crests and troughs. The spokes are separated from each other by a space extending from the wheel rim to the hub.
Abstract:
The present turbine fan rim, turbine fan airless tire and turbine fan hubcap designs are configured to remove air from under the underside of a moving vehicle when rotated in a particular direction, typically in a forward direction. This air movement can create a vacuum below the vehicle, which can create a down force on the vehicle increasing traction between the vehicle's tires and the road surface and lowering the vehicle's center of gravity. This downward force and partial vacuum can thus increase as the rotational velocity of the tires increases, providing greater traction at higher speeds. An additional benefit to these wheel, airless tire, and hubcap designs is the cooling effect that would be created by the flowing air on brake parts that are located near wheels of nearly all vehicles.

Abstract:
A wheel for use on soft granualar surfaces has a circumference having a plurality of concave cavities facing radially outwardly therefrom. The wheel may be used in combination with a cart, dolly, trailer, vehicle or the like.
Abstract:
A variable-diameter wheel 1 includes at least one rim or hub 11 having a predetermined diameter, to which at least one drive axle 14 of the wheel 1 is connected; at least one outer surface external to the hub 11, having a diameter which is greater than the diameter of the hub 11. At least one diameter-variation mechanism 3 is secured to the axle 14 and adapted to vary the actual diameter of the wheel 1 according to the torque applied to the drive axle 14 by at least one propulsion system.
Abstract:
A safety scalpel that incorporates a reusable metal scalpel handle similar in shape and feel to the conventional metal handle preferred by most surgeons, and a disposable blade cartridge that covers the blade before, during and after use, and is easily mounted and released from the scalpel handle. The blade cartridge includes a blade with similar cutting profiles as standard surgical blades, a blade holder that is permanently fixed to the blade, and a blade guard that covers the blade and within which the blade holder is able to slide. The scalpel handle is reusable, while the blade cartridge is disposable. The blade cartridge is attachable and detachable from the scalpel handle.
Abstract:
A removable device for any motor vehicle of which is capable of increasing traction when the drive wheels are trapped in snow, ice or mud.The removable traction device includes a pair of chains being interconnected over the tread surface of a tire and attached to a pair of transversely extending structural bar members on each side of the tire, of which each structural bar member includes a plate member having raised studs on a surface for firmly gripping the rubber wall of tire.Each plate member having threaded rods formed on a surface is connected to a structural part member having holes for receiving therethrough each threaded rod being connected thereby nuts for adjusting and securing a bolt in the width direction of the tire, the bolt passing through a plurality of inverted U-shaped brackets formed on the structural part member and connected by washers and a nut at the opposite lower end of each bar member and to a moving part member, of which a curved metal bar is adapted to be inserted into an opening of the moving part member for tightening and firmly gripping the rubber walls of the tire with the plurality of raised studs formed on each plate member.
Abstract:
A roller wheel assembly for use with golf bag covers or other types of luggage is disclosed. The roller wheel assembly (10) includes a housing (12) and a wheel (14). The housing (10) has an exterior surface (34) and an elongate recessed channel (36). The wheel (14) is elongate and rotatably mourned in the channel (36) of the housing (10) so as to partially protrude beyond the surface (34) of the housing. The wheel (14) includes two circular end plates (42), each having an inner surface (44) and an outer surface (46). A rigid transverse webbing (50) extends radially between the inner surfaces of the end plates, maintaining a planar relationship between the end plates. The webbing includes longitudinal dividers (52) that lie perpendicular to the inner surface of the end plates and run the length of the wheel. The width of the dividers equals the diameter of the end plates, the dividers intersect at the center point of each end plate, and the longitudinal dividers divide the space between the two end plates into a plurality of sections (54). The webbing also includes a plurality of sectors (56), angled with respect to the end plates and located between the longitudinal dividers (52).
