摘要:
A bicycle wheel includes a rim, a tire and a tire retainer. The rim has an annular bridge and a pair of annular flanges with tire retaining ridges. The annular flanges extend outward from the annular bridge to define an annular space. The tire has a pair of annular bead portions that are engaged with the tire retaining ridges of the rim, respectively. The tire retainer is disposed within the annular space. The tire retainer has a support body that is disposed between the bead portions of the bicycle tire. The support body has an axial width that is dimensioned such that the bead portions of the bicycle tire are prevented from disengaging from the tire retaining ridges of the wheel rim, respectively, while the bicycle tire is disposed in the annular space.

The present invention provides a solid light weight nylon foam rod of a particular diameter that is fused together to form a continuous ring that is of a specified circumference, to provide a seal between the inner beads of a standard bicycle tire so when air is pumped through the air valve it creates an air lock between the inner tire area and the nylon foam surface. When mounted on a standard bicycle wheel rim with a standard bicycle tire will create a tubeless bicycle wheel.

A cycle wheel with an axis of rotation and having a median plane perpendicular to the axis, the wheel comprising a rim and a pneumatic tire, in which: the rim includes an upper bridge and at least one left lateral flange extending from the upper bridge and extending radially outward so as to move away from the axis, the upper bridge including a stop positioned on the same side as the left lateral flange in relation to the median plane, so that the left lateral flange and the stop demarcate a left channel, the left channel having, along a radial plane, an opening having an amplitude, a length greater than the opening, the pneumatic tire comprising a casing and at least one non-deformable left bead which, along a radial plane, has a length, a thickness less than the length of the bead, the length of the bead being greater than the amplitude of the opening, the thickness of the bead being less than or equal to the amplitude of the opening; the surface area of the bead cross section being less than the surface area of the channel cross section, and the bead having a transverse modulus between 50 Mpa and 2000 Mpa.
摘要:
An elastomeric tire for mounting onto a rim that is manufactured by casting or molding methods to include an interior arch shaped cavity that is centered under the tire tread to have at least one hundred forty (140) degrees and not more than one hundred eighty (180) degrees of arc, and with the cavity arch duplicated around the tire exterior, below the tire tread. A uniform tire wall thickness is provided that is selected for a particular anticipated load as the tire will carry, the tire supporting the load in compression, and provides ride and wear characteristics are comparable to an appropriately pressurized pneumatic tire carrying a like load, and which tire of the invention interior arch shaped cavity can be pressurized to add to its inherent load supporting character to safely support even greater loads.
摘要:
A vehicle tire wheel has a tire (31) and a rim (32) with elastic members (39) formed on left and right side flange pares (37). The tire (31) is mounted to the rim (32) so that the elastic members (39) cone in contact with left and right side bead parts (35) of the tire (31). The elastic members reduce undesirable force exerted on the left and right side bead parts (35) from the rim (32).

A wheel for working the fields comprises a wheel body comprising a pair of flanges and a spacer, and a tyre cover, generally annular, comprising two side walls, a tread connecting the side walls to one another and an opening opposite to the tread. The tyre cover is mounted on the wheel body in such a way that the spacer is positioned across its opening. The flanges are arranged in such a way as to block the side walls of the tyre cover against the spacer in the vicinity of the opening.
摘要:
A tire for a cycle having a substantially toroidal shape, the tire including a tread adapted to be in contact with the ground, a base adapted to be fixed on the peripheral portion of a cycle rim, and two sides connecting the tread and the base, a lip having a height h greater than twice its thickness e and projecting from the upper portion of each of the two sides, in the vicinity of the tread. The height of the lip is greater than 15% of the width S of the tire in an inflated state. The lips can be constituted by the non-attached extension of the tread and, in particular, by a ply of material affixed to the top of the tire and whose edges are left free on a height greater than 15% of the width of the tire, or each lip can be arranged on an intermediate element adhered on the sides and/or the base of the tire, the intermediate element being capable of being a ring including an annular channel open towards its periphery and two lips projecting from each side of the channel.
摘要:
A puncture resistant tube tor a bicycle tire fitted to a rim of a bicycle wheel includes a tube body inserted into the bicycle tire along a tube insertion recess formed within the bicycle tire and an elastic recess depressed into the tube body adjacent to the portion of the bicycle tire to be fitted to the rim. When the portion of the bicycle tire to be fitted to the rim is shrunk by external force, elastic force is accumulated in the portion of the tube body surrounding the elastic recess while the elastic recess is being shrunk. When the bicycle tire is completely fitted to the rim, the elastic recess is restored to the original shape thereof by the accumulated elastic force, whereby the portion of the tire fitted to the rim is restored to the original shape thereof.
