Abstract:
A rotatable component of a vehicle wheel, especially, a vehicle tire or tire rim, includes, on a portion thereof which is preferably an outwardly visible portion, a pattern at least partially formed in an annular shape comprised of a composition of at least one contrast element serving as a reference and at least one group of further contrast elements.
Abstract:
A fiber reinforced plastic bicycle wheel rim having an aerodynamic section is formed of two mating halves, without additional structural reinforcing members, using laminations of layers of unidirectional fibers crossing one another and having semicircular layers of non-crossing fibers orientated parallel to a point of tangency, the non-crossing layers being proximate tire well apexes and the spoke bed, including, in a preferred embodiment, a lamination of machinable materials at the braking surfaces.
Abstract:
A rim structure for a bicycle wheel that includes, at its periphery, an annular channel designed to receive a tire, such channel being demarcated by an upper bridge devoid of openings with the exception of the valve opening, and two lateral flanges, such flanges having end butts for gripping the tire. The upper bridge has a narrow and recessed central rim well demarcated by a base and two lateral walls, the rim well being bordered by two bead seats that are oblique from the rim well towards the flanges. The invention is also related to a wheel having such a rim and a wheel equipped with a tire mounted without an air tube and having such a rim.
Abstract:
A motor vehicle sheet-steel wheel rim (30, 50), including axially, from the inner side to the outer side, an inner hook (4), an inner seat (5), a connecting zone (7), a mounting groove (9), a hump (11), an outer seat (5) and an outer hook (13), the rim being intended to be joined to a wheel disc (2) under the mounting groove (9), wherein with the rim having a given thickness E in mm at the mounting groove (9), the connecting zone (7) includes a zone (Z5, Znull4) of thickness E1 in mm such that: E/3null0.5 mmnullE1nullE/3 mm; and E1null0.7 mm.
Abstract:
Wheel for bicycles, motor cycles, mopeds, or motor cars, including a rim (11) defining a strip (14) which can cooperate with a respective braking element (15). On the strip (14) there is at least a circumferential seating (16), cooperating in coordination with the braking element (15), in which there is material with a high friction coefficient (17).
Abstract:
A rim for a bicycle wheel with tubeless tyre comprises a radially inner peripheral wall, a radially outer peripheral wall, two circumferential side walls which connect the inner and outer peripheral walls and form two ribs which extend beyond the outer peripheral wall, for anchorage of a tubeless tyre. The inner and outer peripheral walls have two holes facing one another, within which an intermediate tubular element is mounted, connected to which is a valve body of a standard type normally used for bicycle wheels provided with inner tubes.
Abstract:
The present invention provides an improved wheel and tire for simulating the appearance of a larger-diameter wheel mounted within a low-profile tire. The wheel has an inboard side and an outboard side. The outboard side includes a wide outer flange which extends around the outer circumference of the wheel. The outer flange and/or the outboard face of the wheel is preferably detachable from the remainder of the wheel. The inboard side may include a wide inboard flange which is preferably detachable. The flanges preferably cover a substantial portion of the wall of the outer tire within which the wheel is mounted. A design, preferably comprised of, for example, a plurality of protrusions, indentations, and slits, extends across at least a portion of the outboard face of the wheel, including the outboard face of the extended outer flange.
Abstract:
A wheel assembly for child bicycles includes a rim made of Polypropylene and includes two shoulder portions with a groove located therebetween. An annular tire made of Thermoplastic Elastomers which is compatible with the Polypropylene. The tire is engaged with the groove and the shoulder portions of the rim.
Abstract:
A rim for mounting tubeless tires, particularly for bicycles, motorcycles and mopeds, constituted by a profiled element which is curved in a circular fashion and is symmetrical with respect to a centerline plane (P), said profiled element forming an outer annular seat (2) and an inner annular seat which are divided by an annular partition provided with slots arranged opposite the nipples (6) associated with the spokes of said rim, a tire of the tubeless type being associated with said outer annular seat so as to form a pressure chamber. The rim comprises closure elements that engage said slots in order to hermetically separate said outer annular seat from said inner annular seat.
Abstract:
A bicycle wheel rim has spaced-apart annular tire retaining walls, and a reinforced base wall interconnecting the tire retaining walls. The base wall includes left and right corner parts, and an intermediate part extending between the corner parts. The intermediate part has a vaulted portion, which is vaulted radially, and is formed with spoke mounting holes, which are distributed between the vaulted portion and the corner parts.
