20130026812 | SKATEBOARD WHEEL MODIFICATION APPARATUS - The present invention concerns a method and apparatus for the securing a secondary outer wheel surface to a primary skateboard wheel so as to change the performance characteristics of said skateboard. The apparatus is further directed to allowing a user to remove or secure said second wheel without the use of customized tools or devices. The present invention is also directed to securing a secondary wheel surface in a manner that prevents the primary wheel from impeding the motions of the skateboard. Through the use of the present invention, a user can customize the performance characteristics of the skateboard without the necessity of replacing wheels | 01-31-2013 |
20140175856 | SKATE WHEEL FOR MANUAL SKATING APPARATUS - A skate wheel for manual skating apparatus includes a structural body, an outer cover and an inner cover. The structural body is formed in an annular shape and has an outer annular surface and an inner annular surface. The outer annular surface has a plurality of ridges formed thereon. The outer cover is coupled on the outer annular surface to cover the ridges and the inner cover is held on the inner annular surface for covering thereof. Through the uneven surface formed by the ridges, separation of the outer cover can be prevented. A structure with a harder inner side and softer outer side also can be formed. When this structure is used for skate wheels of a manual skating apparatus, durability increases and shock absorption effect enhances, thus can provide longer lifespan and improved comfort, and protect users to meet use requirements. | 06-26-2014 |
20140319899 | WHEEL FOR SPORTS EQUIPMENT - A wheel for a skateboard, roller skate or the like has a radial surface arranged to provide contact with the ground, said radial surface comprising areas of at least a first material and areas of a second material, said second material having at least one mechanical property differing from that of the first material. The first and second materials are arranged in such a way that they form a pattern on the radial surface which varies around the circumference of the wheel. This enables the adaptation of the behavior of the wheel in a very flexible way. | 10-30-2014 |

The truck comprises a base plate and a yoke having a body portion with an aperture through it. There is a bearing member in the yoke next to the aperture. A post is mounted in the base plate and extends through the aperture in the yoke. A novel resilient grommet with a bearing surface on its face is mounted on the post and engages the bearing member in the yoke to restrict arcuate movements of the yoke. A novel wheel bearing is also disclosed which incorporates paired ball bearing casings with bell-shaped members on the outside of each casing slideably meeting each other inside a skate wheel where the bells self adjust the bearings to accommodate imperfections in the bearing seat levelness, bearing seat spacing, axle diameter and axle straightness. | 11-20-2014 |
20150042147 | WHEEL - A wheel comprising a hub and a tire. The hub has an outer tire receiving portion having a largest width smaller than a largest width of the tire. The hub and tire can also include a continuous interface surface. | 02-12-2015 |
301500305 | Mounting on axle or skate | 2 |
20130009448 | WHEEL DEVICE FOR SKATE BOARD OR ROLLLER SKATE - Disclosed is a wheel device for a skate board or a roller skate. A wheel includes a single central hub having an exterior wall and a bore for the housing of rollers, the rollers providing the connection with the hub of a truck; and a tread removably mounted on the exterior wall of the hub. A shoulder of the tread includes a first support face and a second support face, the two faces being parallel to each other and perpendicular to the common axis. The tread is locked in rotation and in axial position on the hub by means of locking screws, including heads abut against the second support face of the shoulder, the screws traversing the shoulder from side to side and attaching on the connecting means of the hub. | 01-10-2013 |
20140054952 | APPARATUS AND METHODS FOR QUICKLY RELEASING A HUB-AND-WHEEL ASSEMBLY - The disclosure provides apparatus and methods of use and manufacture pertaining to a quick release hub-and-wheel assembly. In one embodiment, the hub-and-wheel assembly includes interior and exterior sleeves disposed about a rotatable locking ring that is biased to a latched position. The assembly also includes a quick release wheel having a latch that is configured to temporarily displace a latch-engagement mechanism on the locking ring from the latched position to an unlatched position such that the latch is captured by the latch-engagement mechanism when the latch-engagement mechanism returns to the biased, latched position. The locking ring also includes a manual latch-release mechanism configured to again temporarily displace the latch-engagement mechanism such that the wheel latch is released, allowing the wheel to be removed. Other embodiments are also disclosed. | 02-27-2014 |
301500306 | Hub having tire retention means | 3 |
20080303337 | MECHANICAL FASTENER FOR POLYURETHANE WHEELS - Wheels including one or more retention elements for affixing a polyurethane tire to a hub of the wheel are disclosed. The polyurethane tires of the wheels disclosed are manufactured separate from the hub and affixed to the hub via the retention elements thereby enabling additional manufacturing processes for the polyurethane tires and reuse of the hub portion of the wheels. Such manufacturing processes also allow for more complex polyurethane tire design and combinations of polymers to produce composite wheels allowing for increased comfort and durability. The wheels are particular suitability for use with industrial vehicles, such as lift trucks. | 12-11-2008 |
20160136509 | Roller - A roller includes a rim assembly and a tire assembly. The tire assembly includes a support ring and a tire mounted at the periphery of the support ring. The support ring and the rim assembly are detachably connected by a buckle structure. The buckle structure includes a plurality of elastic accommodating parts disposed on the inner side of the supporting ring, and a plurality of buckling parts disposed at the rim assembly. The elastic accommodating parts and the buckling parts are detachably connected. The elastic accommodating parts protrude out of the inner side of the support ring, and two ends of each elastic accommodating part are separately provided with a protruding first limiting block and a protruding second limiting block. The buckling parts are limited by the first limiting blocks and the second limiting blocks. The rim assembly and the tire assembly of the roller are detachably connected. | 05-19-2016 |
