Description

TECHNICAL FIELD

This invention relates to a winch and more particularly to a wheel winch to be used as a specific component with a vehicle wheel. The vehicle wheel of course is a necessary component to facilitate motion of a vehicle. Sometimes however additional components are necessary to assure motion of a vehicle wheel when the vehicle gets immobilized such as when a vehicle is trapped in mud, snow or such other undesirable conditions. This is a situation of utmost concern particularly because of the safety implications for the vehicle as well as any persons that may be traveling in the vehicle. This ongoing concern for safety dictates that vehicles from time to time require the use of a winch to assist in freeing a vehicle from such conditions. Thus motorist have to consider various alternatives to assure that when such conditions exists they can immediately address the situation. One of the popular alternatives for motorist in this situation is the use of wheel winch mechanisms and the like.

Such devices are normally mountable to the vehicle wheels. Additionally, they may be power driven devices and frequently are even hand driven. Still further they are likely associated with more than one wheel on the vehicle, and frequently permanently mounted on at least one wheel. These wheel devices can be quite complicated and are expensive and not always easy to use.

Accordingly it is desirable to have a device that can be used on one wheel of the vehicle that is uncomplicated in its construction thereby making it inexpensive and easy to use.

BACKGROUND ART

Attempts have been made to provide devices to facilitate wheel winch assemblies. One such device is illustrated in U.S. Pat. No. 6,095,451. In this arrangement two of the vehicle wheels must be used. The wheel winch of this invention includes a plurality of spaced brackets which are fastened to the surface of the drive wheel of the vehicle. The brackets include a plurality of retractable fingers which are provided to engage and support a rope thereon. Still another bracket is attached to a non-drive wheel of the vehicle. This bracket cooperates with the brackets on the drive wheel and the rope, to facilitate the action of the winch and accomplish its objective when in operation. Another apparatus is disclosed in U.S. Pat. No. 4,778,126. This invention discloses a wheel winch having a first hub assembly attached to a drive wheel of the vehicle and a second hub assembly fixedly attached to a non-drive wheel of the vehicle. The first and second hub-assemblies cooperate with a cable to facilitate the winch action of the invention. Although devices such as these may achieve the desired result these kinds of structures may be considered somewhat complex. Additionally they require that two wheels of the vehicle be used to accomplish the desired result, and frequently has portions permanently fixed to the vehicle. Thus the commercial viability remains to be seen. Therefore there is an ongoing need for a wheel winch that is uncomplicated structurally, and low in cost while still providing a safe method for aiding in pulling a vehicle from a mired condition.
