Abstract
A marker is provided for use in combination with a vehicle wheel for indicating wheel rotation for a truck. The marker fits onto the wheel and turns with the wheel. The marker has a reflective end to allow vision during less visible occasions. The marker is mounted on the wheel stud and when the wheel stud is fastened the wheel marker is pressed between the rim and the wheel nut. The markers reflective end rests on the outer portion of the rim.
Description
WHEEL ROTATION MARKER
FIELD OF THE INVENTION
The present invention relates to a combination of a vehicle wheel and a marker mounted thereon for indicating to a driver of a vehicle that the wheels of the vehicle are properly rotating.
BACKGROUND OF THE INVENTION
When driving a large truck a driver is unable to see the rear tires rotate. Tires occasionally lock due to ice and many other different reasons and when the tires lock a driver has no indication of the problem. The present invention allows the driver to identify whether a tire is rotating or not. A driver will see the device and be able to stop before any permanent damage or injuries occur.
SUMMARY OF THE INVENTION
According to one aspect of the present invention there is provided a combination of a vehicle wheel and a marker for providing visual indication of rotation of the vehicle wheel comprising:
the vehicle wheel having a wheel hub;
a wheel rim having an outer rim edge and a central disk mounted on the hub;
and a plurality of threaded fasteners;
the marker consisting solely of an elongate flat strip of plastics material having a hole at one end arranged to be engaged over a single one of said threaded fasteners of the vehicle wheel;
the strip having a portion thereof at the other end which is formed of a readily visible material;

DETAILED DESCRIPTION
A marker 1 for indicating rotation of a wheel 3 comprises a flexible elongated strip which is sufficiently rigid material so that the marker 1 remains in contact with the rim edge 5 of the rim 7. The marker 1 is a flat strip of nylon material wherein the top side 9A and the bottom side 9B is of constant width and is sufficiently wider that that of the wheel nut 11 so it can be tightened with the wheel nut 11 onto the centre disk 13 of the rim 7. The first edge 15A and the second edge 15B of the marker 1 is sufficiently thin to allow the wheel nut 11 to compress the inner most end 17 of the marker 1.
When the marker 1 is tightened onto the wheel 3 the outer most end 17B rests on the rim edge 5 in order for the reflective material 19 to be visible to the driver of the vehicle. The reflective material 19 is attached to the outer most end 17B of the marker 1.
As the wheel nut 11 is tightened to the center disk 13, the inner most end 17 of the marker 1 is compressed forming a compressed portion 21. The wheel nut 11 is tightened by screwing it onto the wheel stud 23. The inner end 17 has a hole 27 shaped and arranged to fit over the wheel stud 23 of the vehicle, which the wheel stud is inserted through. The marker 1 has a width which is greater than that of the hole 27 by an amount sufficient only to mount on the wheel stud 23. The wheel stud 23 has a wheel stud head 25 which is on the opposing side of the center disk 13.
The center disk 13 has a circular space 29 which the wheel stud 23 is inserted through. The circular space 29 has an outer ridge 31 which enables an 5 exact seal between the stud 23 and the nut 11. As the stud 11 is tightened the compressed portion 21 is clinched such that the required force is communicated through the marker 1 to the wheel stud 23 to hold the wheel in place.
In the second arrangement, the strip is modified so that it is unitary and wholly formed from a readily visible plastics material such as a bright yellow or orange nylon. Thus the outer end is directly visible without the necessity for a reflective strip. In this embodiment also, the strip is not pinched between the wheel nut and the wheel disk but is instead attached by an additional lock nut 30 which pinches the strip at the hole between the wheel nut and the lock nut to hold the strip in place.
Different wheel constructions of course require different length of the strip. Also different hole size is required for different stud diameters. In practice, three styles of wheels are currently commercially available. Two of these require strips of 16 inch length and a width of 1.5 inch and a thickness of 0.125 inch. The hole size is either 1.125 inch or 0.875 inch. In another style, the length is 10 inches and the hole size is 0.75 inch. The material is yellow UV resistant plastic No.
07100001. Only one device is installed on each wheel. The device does not interfere with noticing whether a wheel nut is loose. The device is visible to the driver from the cab but does not encroach on the maximum allowable road width.
While one embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
Figure 5 is a partial horizontal cross section of a second arrangement the present invention mounted on a wheel.
