Abstract: A multi-piece safety wheel includes a plurality of circumferentially spaced, interlocking bosses and tabs on the inner rim portion and outer rim portion. In the event of improper disassembly of the wheel with an inflated tire mounted thereon, any failure of the wheel assembly fasteners will result in the outer rim portion separating from the inner rim portion a sufficient distance to vent air pressure from within the tire, at which point the interlocking bosses and tabs resist further movement of the outer rim portion. The outer rim portion is thereby resisted from becoming a potentially dangerous projectile. A method of safely deflating the tire upon improper disassembly of the multi-piece safety wheel is also provided.

Abstract: A skate wheel includes a reusable hub and a replaceable tire. The hub consists of (i) a rim with an integral clamp ring, (ii) an attachable clamp ring that attaches to the rim after a tire is mounted on the rim and (iii) a threaded ring which fastens onto the rim and secures the attachable clamp ring to the rim. Each of the clamp rings includes an inwardly pointing arm. These arms extend into annular grooves on the sides of the tire, to grip the tire and hold it in place on the rim. In a preferred embodiment the outer ring screws onto the rim and in position against the clamp ring, to retain the claim ring on the rim. To replace a worn tire, a user unscrews the outer ring, removes the attachable clamp ring and then removes the old tire from the rim. He then slides a new tire onto the rim, holds the tire in place with the attachable clamp ring and secures that ring in place with the outer ring.

Abstract: This invention provides an improved aircraft wheel rim wherein a demountable tire bead flange has an annular chamfer within the outboard end of the flange bore, and a split lockring which cooperates to maintain the flange on the wheel rim body has an outer surface chamfer which matches the flange bore chamfer, the angle of the flange bore and lockring surface chamfers being determined by the coefficient of friction of the material comprising the wheel rim assembly such that a compressive wedge-locking load force exists at the chamfer joint as may be imposed by inflation of a rim-mounted tire.

Abstract: An off-highway wheel rim has a flange formed with a frustroconical outwardly directed band at its radially inner surface. The band abuts an inwardly directed surface on an upturned edge of the rim so that in the free body state the opposed surfaces diverge. Upon inflation of the tire, the faces are brought into engagement by the pressure forces within the tire to produce face-to-face contact between flange and rim.

Abstract: A driving mechanism having a driver-loose key provided between a rim base and a bead seat band mounted about the rim base of a multi-piece rim which has the rim base, the bead seat band, a pair of side rings and a lock ring. The driver-loose key is cross-shaped with the two portions thereof which are adapted to be inserted into a groove extending in the circumferential direction of the rim base between the rim base and the bead seat band being arc-shaped so as to have substantially the same curvature as that of the groove. With this structure the slippage of the bead seat band on the rim base can be minimized and the durability of the mechanism can be increased.

Abstract: An annular locking ring for use on an aircraft wheel that has a pair of separable wheel sections wherein the locking ring has a lobe section and a leg section. The cross-sectional shape of the leg section has a pair of spaced linear portions that are interconnected at their one ends while the cross-sectional shape of the lobe section has a curvilinear portion and a linearly extending portion that intersects one of the linear portions of the leg section. The curvilinear portion of the lobe section has one end that merges with the other one of the spaced linear portions. The extension of the one linear portion of the leg section makes an acute angle with the linear portion of the lobe portion. Alternatively, the lobe section may have two spaced linear portions separated by the curvilinear portion with one of such linear portions merging with one linear portion of the leg section and with the other one of such linear portions of the lobe section intersecting the other linear portion of the leg section.

An angle of a contact surface formed between the bead seat band and the lock ring is between 30.degree. and 40.degree. relative to an axis of the wheel so that slip at the contact surface between the bead seat band and the lock ring due to a load from a tire can be effectively prevented, while the sufficiency of the strength of each member in the wheel can be ensured.

Abstract: A go-cart vehicle, made from high strength, molded engineering plastics, has a steering shaft tilt assembly which includes a steering shaft (66) slidable in a pivot bushing (70) carried by a bracket (73). The shaft pivots at a U-joint (78) and the bracket (73) pivots at its base. The bracket carries a detent--a cylinder (94) attached to the base (74) of the bracket (73). The cylinder (94) has a number of holes (93) to engage a latch pin (92) which is controlled by a release lever (95) operated by a release button (102). The shaft (66) may be adjusted to varying angles of tilt by moving the latch pin from hole to hole which motion causes the bushing, shaft and bracket to pivot in unison as the shaft slides in the bushing. The vehicle combines a change in caster angle (12) to about 12 degrees with a short, rigid chassis (2) and a live axle (45) to make it possible to turn a sharp corner at speeds of 20 mph or less.

Abstract: A three-piece wheel for vehicle tires for providing a greater positive offset comprising a wheel center, an inner rim and an outer rim wherein the rims are secured at their radially directed bases to a disk mount on the wheel center by a plurality of threaded fastening members. The inner rim defines an elongate curved tire support portion terminating at one end in an inner rim flange and at the other end in a radially directed base. The outer rim is generally T-shaped defining an outer rim flange portion for securing the tire in combination with the inner rim flange on the inner rim, a tire support portion extending over a portion of the inner rim for supporting the tire in combination with the inner rim and a radial base portion disposed inwardly of said tire support portion for supporting said tire support portion and for use insecuring the outer rim to the inner rim and wheel center.

Abstract: An annular ring-shaped run flat device is used in tires to permit continued use of the tire even when the tire is operating at low pressure or is completely deflated. This device is comprised of a rigid section and a non-rigid section. The tire, when it collapses, due to a reduction in pressure, comes to rest on the surface of the non-rigid, resilient, impact resistant section. This device is easy to assemble, can be used with conventional multi-piece rims, is light weight, durable and capable of absorbing impact under both inflated and deflated conditions. The device can also be used as a positive and non-positive bead spacer to prevent dismounting of the tire beads when tire pressure drops.

Abstract: An assembly for mounting tubeless tires on tube type rims. The assembly includes a pair of cooperating annuluses that define respective seating surfaces each of which are adapted for receiving one of the companion beads of the tire. One of the annuluses is telescoped onto the rim and positioned adjacent the rim flange integrally formed with the rim proximate one of its axial end portions. A locking annulus secured to the opposite axial end portion of the rim is adapted for receiving the companion bead and can be readily secured to or removed from the rim for purposes of mounting or demounting the tubeless tire without forcing the beads over a flared flange. The locking annulus may be mounted on a variety of conventional tube type rims while maintaining the bead seating surface at a predetermined spaced location from the rim wall. A suitable pneumatic inner tube inserted in the tire serves to prevent air from escaping the confines of the tubeless tire which may have damaged sealing properties.

Abstract: Two-piece rim for mounting tires, single or dual, on a wheel. The removable bead ring has an axial projection intended for engagement by restraining means mounted on the wheel in the event a tire on said rim is unintentionally deflated. Various forms of restraining means are provided.

Abstract: A rim for tubeless tires is improved by having the outer elastic annular sealing ring housed in a groove located in a conical bearing surface of the fixed locking device forming a thickening of increasing diameter which is firmly connected with the rim base.
