Abstract
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.
Claims8
An anti-skid device for enhancing traction on slippery roads comprising:
- a housing defining a cavity and having housing teeth along an inner periphery of the housing;
- at least three arms protruding radially from the housing;
- a hub rotatable within the cavity of the housing by a handle, the hub is configured to extend the at least three arms in a direction outward from the hub when the hub is rotated in a first direction and retract the at least three arms in a direction inward to the hub when the hub is rotated in a second direction opposing the first direction;
- each of the at least three arms having an associated anti-slip element extending from a side surface and being configured to contact a tread surface of the vehicle tire;
- and
- a lock comprising lock teeth configured to lock the hub in relation to the housing to prevent extension of the at least three arms when the anti-slip elements are engaged against the tire tread, wherein the lock comprises a locking element located between the hub and the housing, and the lock is movable between a first position where the lock teeth engage the housing teeth preventing rotation of the hub and a second position wherein the lock teeth are out of contact with the housing teeth allowing rotation of the hub.
