DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
My invention relates to a traction augmentation device for mounting about a movable boss to augment the traction in the footprint of engagement between the boss and an interactive surface thereopposite when the interactive surface drives or is driven by the boss in the movement thereof. The boss may be a generally square or round plate-shaped boss such as a brake pedal in the cab of a vehicle, a generally elongated or oblong plate-shaped boss such as the sole of a shoe, a generally cylindrical wheel-shaped boss such as the ground engaging wheel of a vehicle, or any other structure of similar nature which is operatively engaged with an interactive surface thereopposite, such as a ground surface thereopposite, a machine surface thereopposite, or even the sole of a shoe thereopposite in the case of a brake pedal, to drive or be driven by the surface in the movement thereof. In each instance, the structure, e.g., the boss, is operatively circumposed relatively radially outwardly about an axis of a carrier on which the boss is operatively supported, such as the arm of a brake pedal, the top of a shoe, or the axle of a wheel, and is connected to one end of the carrier so as to have relatively axially inwardly and axially outwardly oriented sides thereon, relative to the carrier. The boss has a central portion thereof which is intrapositioned across the end of the carrier so as to have a face on the axially outwardly oriented side thereof, and an outer peripheral portion thereof which is circumposed about the central portion thereof and has a generally annular surface on the axially inwardly oriented side thereof. In addition, the boss has an outer periphery circumposed about the flange portion thereof which is interposed between the axially inwardly oriented annular surface of the flange portion and the face of the boss.
Depending on its function, the boss will engage the interactive surface at the outer periphery thereof, such as in the case of the wheel of a vehicle, or it will engage the interactive surface at the face thereof, such as in the case of a shoe sole or a brake pedal. Furthermore, the boss and the interactive surface will engage with one another over a so-called "footprint" of engagement therebetween, and accordingly, the inventive traction augmentation device is commonly adapted so that when mounted on the boss, it will operatively interpose traction elements between the boss and the interactive surface over the area of the footprint therebetween.
BACKGROUND OF THE INVENTION
The traction augmentation art is crowded with a wide variety of devices for the purpose. And many of the devices have seen commercial use. Many have also functioned well for the purpose. But all have suffered from the fact that mounting them on the boss has been a cumbersome process, usually involving a plurality of steps, including a step in which two or more components of the device are fastened together to releasably secure the device about the boss. In the so-called "tire chain art" in particular, this has always been a troublesome problem inasmuch as each tire is commonly engaged with a ground surface thereunder, and to mount the device, it is often necessary either to first lift the tire away from that surface, using a jack under the vehicle, or to first interengage the device between the tire and the surface, by driving the vehicle over it, and then to reach around the outer periphery of the tire to the posterior side thereof, to fasten or otherwise secure the device about the tire before the vehicle can be driven away on that tire. Often too, a further adjustment must be made in the device after the vehicle has traveled a predetermined distance, to assure that the device is tightly engaged about the tire and coaxially aligned with the axle of the wheel. Further adjustments may also be needed at a later time to assure that the device remains tightly engaged about the tire, and is still coaxially aligned with the axle of the wheel.
What is needed then is a device which is mountable so simply on the t
