Abstract

An anti-theft/slipping device comprises a hub (1) and three radially extending arms (10, 11 and 12) which are disposed at an angle to each other and are bent to extend over the periphery of a vehicle wheel. Two arms (10 and 11) are permanently mounted on the hub and the third arm (12) is releasably mounted to permit removal of the device. By providing one of the arms with a short radial extension 18, the device can be used as a vehicle security device. Alternating bent-over portions of the arms can be provided with outwardly facing serrations to form snow-grips.

Description

SPECIFICATION Devices for fitting to vehicle wheels This invention relates to devices for fitting to vehicle wheels.
According to the invention a device for fitting to a vehicle wheel comprises a central hub and three arms which extend from the hub at an angle to each other and are bent at their outer end to locate over the periphery of a wheel, two of said arms being permanently mounted on said hub and the third arm being releasably mounted on the hub so that it can be removed from the hub to permit the device to be removed from a vehicle wheel.
To facilitate carriage of the device when it is not mounted on a vehicle wheel, one of the two arms which are permanently mounted on the hub is pivotally mounted on the hub so that it can be rotated from its operative position in which it abuts a stop to an inoperative position in which it lies adjacent the other arm. When in its operative position the inner end of the pivotal arm advantageously defines a gap with the end of the other of the two arms, through which gap the third arm passes with a close fit in order to lock the three arms in their angular orientation.
The device of the invention may be adapted to -be used as a vehicle security device in which case the third arm may be locked in position by a key operated lock and one of the arms may be provided at its outer end with a short radial extension so that it is effectively longer than the other two arms. Hence any attempt to drive away a vehicle having a device in accordance with the invention mounted on one of its wheels would at least cause a clatter due to the outer end of the longer arm periodically coming into contact with the road surface.
The device of the invention may be adapted to be used for improving the grip of a vehicle wheel in snowy or icy conditions, in which case the portions of the arms extending over the periphery of the wheel may have outwardly directed serrations provided for example on separately formed strips welded to the arms. In this adaptation of the device the third arm may be secured to the hub by the'over-centre clamp.
One device in accordance with the invention and adapted to be used as a vehicle security device will now be described by way of example with reference to the accompanying drawings, in which Figure 1 shows a front view of the device, and Figure 2 shows a side view of the device.
The device comprises a central hub 1 formed from two circular plates 2 and 3 spaced from each other by spacer members 4 and 5 welded to one of the plates 2 and 3 and secured together by bolts 6 and 7. Three arms 10,11 and t2 extend from the hub 1 at an angle of 1200 to each other about the centre of the hub. At their outer ends the arms 10, 11 and 12 are bent through an 'L' shape so that they can be fitted over a vehicle tyre with one limb of the 'L' extending across the tread and the other limb of the 'L' extending down the inside wall of the tyre. It will be appreciated therefore that in use of the device the hub 1 will cover the wheel hub and so prevent access to the wheel nuts.Also by making the device of a strong material such as stainless steel and ensuring that any releasable securing devices such as threaded bolts are accessible only from that side of the hub which faces the wheel hub, unauthorized removal of the device from a vehicle is extremely dificult.
The arms 10 and 11 are permanently mounted on the hub 1 and extend in the space between the hub plates 2 and 3. The arm 10 is fixed against movement relatively to the hub 1 by welding it to one of the plates and also by the bolt 6 which passes through it. The arm 11 is pivotally mounted between the plates 2 and 3 on pivot bolt 1 3 so that it can be pivoted from its operative position shown in the drawings to a position in which it lies adjacent to the arm 10 to facilitate carriage of the device when not in use. In its operative position the arm 11 abuts against radial shoulder 14 provided by spacer member 5.
The arm 12 is releasably mounted on the hub 1 so that it can be removed from the hub 1. The arm 1 2 is a sliding fit between the two plates 2 and 3 and in its operative position shown in the drawings is a close fit between the radial shoulders 15 and 1 6 of the spacer members 4 and 5 and between the inner ends of the arms 10 and 1 which are cut so that they provide a parallel sided channel for the arm 12. The arm 12 thus extends diametrically across the hub 1 between the plates 2 and 3 and projects a short distance beyond the hub 1. A hole 17 is provided in the projecting portion of the arm for receiving a padlock to lock the arm 12 to the hub 1. It will be appreciated that when the arm 12 is fitted it prevents pivotal movement of the arm 11 so that the latter is also effectively locked in position.
The road engaging surface of the vehicle wheel to which the device is fitted is the ends of the arms 10, 11 and 12. The arm 10 is provided with a radial extension 18 so that it is effectively longer than the other two arms. Any attempt to drive away the vehicle will at least therefore cause a clatter.
The device is fitted to a vehicle wheel with the arm 12 removed and with the arm 11 pivoted away from the arm 10 so that the outer ends of the arms 10 and 11 fit over the tyre at approximately 1200. The arm 12 is then slid into position between the plates 2 and 3 and locked with the padlock.
