The first end (17A) and the second end (17B) of the reinforcement are arranged one upon the other so as to form an overlap.

A firm-grip rim includes two walls, an internal ring, an external ring and two flanges. The walls extend in an annular manner. The internal ring is formed between the walls. The external ring extends around the internal ring and includes two lateral portions connected to the walls respectively. Each of the flanges extends outward from a corresponding one of the walls in a radial direction so that there is a corner between it and a corresponding one of the lateral portions of the external ring. Each of the flanges includes an internal side formed with a grip device.

A bicycle rim may control the two beads of the tire with separate bead channels for each bead and a center bridge extending between the two bead channels. A bicycle assembly comprises a bicycle rim having an attachable annular strip formed separately from the bicycle rim and attached to the bicycle rim along a center line of the center channel. The annular strip comprises a set of strip sidewalls and a center section extending between the strip sidewalls, wherein the strip sidewalls are spaced at less than the channel width such that the strip forms a pair of bead channels in cooperation with the channel first outer sidewall and channel second outer sidewall.

A two-piece rim and tire assembly. The tire is held to the rim by fasteners extending through flanges integral with the tire main body and then into the rim. Further, the outer edges of the rim clinchably mount the tire main body thereto. A flexible overhanging portion extends outwardly of the tire main body minimizing dirt and mud accumulation on the tire and rim. A bearing is held within the rim by a ring.

A bicycle rim has rim a pair of rim flanges that defines a tire channel. A rim strip extends across the tire channel. The rim strip includes a pair of flange bumpers configured to cover the rim flanges. The flange bumpers each define a flange channel in which one of the rim flanges is received. A pair of safety humps define corresponding tire seating sections where a tire is seated when inflated. The rim strip further includes a drop seal that seals with the beads of the tire to facilitate seating of the tire during inflation.

A system. The system includes a one-piece wheel, a tire mounted to the wheel, and an antiroll off assembly. The wheel defines an axis of rotation and includes a disc portion which defines a central opening, and a rim portion which is connected to the disc portion and defines first and second flange portions, first and second seat portions and a well portion. The anti-roll off assembly is positioned in the well portion and includes a band, a plurality of filler assemblies connected to the band and a coupler assembly configured to adjust a tension force applied to the band. The coupler assembly includes a first trunnion in contact with the band and having a first threaded opening, a second trunnion in contact with the band and having a second threaded opening, and a threaded member threadedly engaged with the first threaded opening and the second threaded opening.

A wheel rim retainer includes an annular unit, a first end connecting member movably coupled at one end of the annular unit, and a second end connecting member movably coupled at an opposed end of the annular unit. The annular unit includes a plurality of hinged members movably coupled with each other in an edge-to-edge manner, wherein each of the hinged members has a width larger than a width of the wheel well. The second end connecting member is detachably coupled with the first end connecting member for encircling the hinged members around a hub surface of a wheel rim to cover a wheel well thereof so as to prevent a bead of a tire falling at the wheel rim when the tire is deflated.

A vehicle wheel comprising a wheel rim having first and second sidewalls defining a rim trough and an opening extending through a portion of the wheel rim, a tire having a tire bead positioned in the rim trough in engagement with the first sidewall, and a bead lock positioned in the rim trough adjacent the tire bead. The bead lock is movable between a locked position and an unlocked position. The bead lock includes an actuator positioned in the opening with a portion accessible from outside the rim, and a band positioned in the rim trough with two free ends movable relative to each other and a side edge engaged with the tire bead. The side edge includes a cut out that creates a recessed edge that is not engaged with the tire bead.

A transient heating burner including at least two burner elements each including a distribution nozzle configured to flow a first fluid and an annular nozzle surrounding the distribution nozzle and configured to flow a second fluid, the burner also including a controller programmed to independently control the flow of the first fluid to each distribution nozzle such that at least one of the distribution nozzles is active and at least one of the distribution nozzles is passive, wherein flow in an active distribution nozzle is greater than an average flow to the distribution nozzles and flow in a passive distribution nozzle is less than the average flow to the distribution nozzles, wherein the first fluid contains a reactant that is one of fuel and oxidant and the second fluid contains a reactant that is the other of fuel and oxidant.

A beadlock to secure a tire to a wheel. The beadlock comprises a first grip element and a second grip element. The first grip element is welded to the outer rim of a wheel. A bead of the tire is positioned over the first grip element. The second grip element has a plurality of rib elements angularly spaced around its periphery. The second grip element is secured to the first grip element such that the ribs grip the bead to hold it in place and secure the tire to the wheel.
