摘要:
A traction aid apparatus for a motor vehicle wheel. The apparatus has an elongated main body; a first securing member located at the first end or near the first end of the elongated main body and projecting downwardly comprising a surface for engaging a first side wall of the motor vehicle tire; a second securing member projecting from the elongated main body comprising a surface for engaging a second side wall of the motor vehicle tire opposite the first side wall of the motor vehicle tire, a tension mechanism connected to the elongated main body or the second securing member; and a flexible wheel engaging member that is configured to pass through an aperture in the motor vehicle wheel to the tension mechanism to secure the traction aid apparatus to the motor vehicle wheel.

Disclosed herein a system and device for providing traction for car wheels in situations in which a vehicle may be stuck or immobilized. The device or system, or Flexible Traction Track, is designed to assist a motor vehicle operator to successfully recover from being stranded off paved road surfaces such as sand, dirt, mud, gravel, ice or snow. The basic elements and features of the preferred embodiment include two tracks providing traction, connected by cables to enable proper place around or under the tire. During use, section one (1) is positioned against the front (leading) edge of a (spinning) tire mounted on any of the powered wheel (axel), between the tire and the ground cover or surface. Once section one (1) and three (3) have been bridged by section two (2) around a tire, the operator may then successfully drive over the terrain.

A mobility device for moving an object across a surface having a non-planar obstruction to allow movement of the object over the obstruction. The mobility device has a walking wheel assembly and an attachment mechanism. The walking wheel assembly has at least two wheels and an offset camshaft. The offset camshaft has a lobe associated with each wheel. The lobes are in a non-linear relationship such that one wheel is a leading wheel and one wheel is a trailing wheel. The offset camshaft allows the leading and trailing wheels to pivot upward and downward independent of each other. The attachment mechanism attaches the walking wheel assembly to the object. The mobility device can include a deflector assembly having a pair of deflector arms that are pivotally connected to a cam-axle which is attached to the offset camshaft to help guide the mobility device over non-planar areas.

A universal rotating module is provided. The universal rotating module comprises a main body including a first portion and two second portions; a main shaft passing through the through groove to pivotally connected to the main body; two bearings sleeved on and pivotally connected to the second portions along the second direction, respectively; two rollers pivotally connected to the second portions along a third direction, respectively; two hemispherical casings fixed to the two bearings, respectively. The first portion includes a through groove extending along a first direction, and the two second portions protrude from opposite sides of the first portion along a second direction, respectively. Each of the hemispherical casing includes a through hole at the top, and a portion of each of the rollers is exposed out of the corresponding through hole.

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.

The invention relates to a shield-shaped side-wall protection element for a vehicle tire and to a protective device for vehicle tires. In order to provide a side-wall protection element for vehicle tires that can optimally protect a tire side wall under rough conditions, that can be produced economically, and is easy to install, the invention provides a shield-shaped side-wall protection element for a vehicle tire, comprising a radially inner base, an outer edge, which forms the radially outer end and which extends in a circumferential direction, and with a shield segment, which extends from the outer edge at least to the base, wherein the outer edge is at least partially offset axially inward from the base). The protective device for vehicle tires according to the invention comprises a plurality of shield-shaped side-wall protection elements arranged overlapping in the manner of shingles in a circumferential direction.
