This present invention relates to an anti-skid device adapted to being mounted on tyres of the vehicle wheels to provide traction and wheel to ground contact enhancement in snowy and icy conditions. The device includes a central hub from which protrudes radially three arms which are extended at the outer end by anti-slip components transversally embracing the tread of the tyre. The inner area of the anti-slip components in contact with the tread is designed to increase friction to prevent circumferential displacement of the anti-skid device. When the car is moving a horizontal depression is formed at tyre-ground contact and this provokes a change in wheel radius. Integrated springs follows the depression by moving radially inwards to ensure that the anti-skid device stays attached to the tyre even when an anti-slip component is at the ground contact point at the bottom of wheel. A fastening handle integrated into the hub secures the device on the wheel by simultaneously tightening the arms radially inwards.

A traction enhancing device for a vehicle includes a plurality of spikes that is coupled to and extends from an outer face of a panel that is bendable and configured to conform to a circumference of a tire. A plurality of first straps and a plurality of second straps are coupled to a first edge and a second edge of the panel, respectively. Each second strap and an associated first strap are configured to loopedly position around the tire and a rim of a vehicle. Each of a plurality of first couplers and each of a plurality of second couplers are coupled to a respective first strap and a respective second strap, respectively, distal from the panel. Each second coupler is positioned to couple to an associated first coupler to couple the panel to the tire, positioning the spikes to insert into a substrate to increase traction of the tire.

Illustrative embodiments of systems and methods for improving traction of a bicycle are disclosed. The invention described are traction loops comprised of a strap having projections extending therefrom. The loops are fastened around the width of the tire using a fastening device. The loops may be easily applied and removed to provide the rider with flexibility to use the loops on slicker surfaces and remove them when riding on drier surfaces. The loops may further be easily stored on the bike when not in use.

An airless flexible tire comprising a belt, drive lugs, and traction lugs. The drive lugs extend inwardly from the belt and form annularly spaced, rigid, high torque points. The traction lugs extend outwardly from the belt and are annularly offset from the drive lugs so as to form flexible sections that deflect radially inwardly when the tire engages the ground. Each traction lug has an effective height as a function of its actual height, the angle that the traction lug extends relative to a radial axis, the angle of the traction lug's distal surface, and the amount the tire deflects radially inwardly near the traction lug so as to at least partially equalize a rolling radius of the wheel to reduce torque generated near the high torque points.

The cleaning device is for cleaning the inner surface of pipes. The method is for manufacturing the cleaning device and the use is of a vehicle anti-skid chain for cleaning the inner surface of a pipe. The cleaning device has a sleeve, to which are attached studded chains composed of steel links and surface hardened.

This present invention relates to an anti-skid device adapted to being mounted on tyres of the vehicle wheels to provide traction and wheel to ground contact enhancement in snowy and icy conditions. The device includes a central housing 2 from which protrudes radially three arms 3 which are extended at the outer end by anti-slip components 10 transversally embracing the tread of the tyre. The anti-skid device have a locking mechanism that consists of a locking element 24 with teeth engaging with teeth on the inner circumference of the housing 2. A handle 16 integrated into the hub 4 interfaces with the locking element 24 to securely maintain the locked status when the device is mounted onto the wheel.

A detachable chain apparatus for use with a vehicular tire is provided. The chain apparatus includes a plurality of chain assemblies disposed on the vehicular tire, each chain assembly having an elongated cable extending through a pair of slider members to create a first end loop portion proximate the first slider member, a second end loop portion proximate the second slider member, and an intermediate parallel cable portion of the elongated cable between the pair of slider members disposed on a tread portion of the vehicular tire, a plurality of sleeves rotatably mounted to the intermediate parallel cable portion of the elongated cable, and an elastic strap coupled to both the first and second end loop portions of the elongated cable. Tension in the elastic strap secures both the first and second end loop portions of the elongated cable within an interior of the tire.

A tire traction device can include a strap configured to extend around at least a portion of a vehicle tire; and a traction plate. The traction plate can have a lower surface adapted to sit on a circumferential portion of the vehicle tire, an upper surface opposite to the lower surface, a channel configured to receive the strap, and one or more paddles extending upward from the upper surface. Other features, embodiments, and kits, and related methods are also described.
