This invention relates to the field of motor vehicles. More specifically, anti-skid devices and tire chain traction devices.
Many states require the motorist to carry and put on snow tire chains when weather conditions become icy or snowed over. In addition to hefty fines and endangering oneself and other motorists, drivers that install chains improperly or not at all, risk property damage and even death. The embodiment of this invention is to provide the vehicle operator a convenient and safe method of deploying snow tire chains in hazardous winter conditions. Millions of dollars are spent annually due to vehicle accidents wherein the motorist slid into a vehicle or another vehicle slid into the motorist. This apparatus is designed to resolve some common problems motorist are tasked with when installing standard snow tire chains. The apparatus is designed to throw chains between the tire and road surface producing significantly more traction than the standard snow tire chain. While standard snow tire chain manufacturers continue to evolve with different designs and methods to install chains, this apparatus eliminates all of the hassle and difficulty of putting on chains. This apparatus is engaged by manually lowering the apparatus handle.
Many motorists complain of having to install standard snow tire chains in poor weather conditions. The complaints range from cold numb hands to the difficulty of getting the chains installed properly. For commercial drivers, the complaint is a loss of time having to stop sometimes for thirty to forty-five minutes or more to install tire chains. Motorists complain of replacing lost chains, struggling in the dark to install chains in adverse weather conditions, chains breaking loose and wrapping around the vehicle axle and vehicle damage as a result of broken chains. This apparatus can be deployed in under two minutes. The apparatus is always with the vehicle and require no storage. This apparatus is designed to be a convenient and simple solution to manually deploying snow tire chains.
In the field of motor vehicles and transportation, there is a problem when ice and snow conditions exist that cause loss of vehicle traction and skidding of vehicles. To address this problem, traction devices have been added to vehicles that use tire chains in order to improve traction and prevent skidding. In addition to the problem of decreased vehicle traction, another problem is the lengthy amount of time for a vehicle operator to put on or to engage the vehicle traction devices. There have been many U.S. patents issued in this field to address these problems in years past. Although, there are specific problems involved in the current state of technology available to solve these problems. The most common problem with existing solutions is that they require the vehicle to have or use a pneumatic system. This invention is a non-pneumatic and non-electrical apparatus and is engaged by a manual operation of a handle. Another problem with existing solutions is that the chain wheels do not allow the tire chains to flex on harsh road conditions. This causes stress on the device and can cause the device or chain wheel to break. This invention incorporates a unique spring link or other flexible material to allow this flexibility. Provided is a list of known U.S. patents issued in this field that have attempted to address the loss of traction and loss of time for engagement of traction devices in prior years:
The embodiment of this invention is to provide the vehicle operator a convenient and safe method of deploying tire chains in hazardous winter conditions. Prior to this invention, vehicle operators solve this problem by manually placing standard tire chains around the tires, installing an alternative traction cover over the tires, installing a pneumatically operated chain traction system, or installation of studded tires. This apparatus is designed to resolve common chain failures. Too often the chains are not secured properly, causing the chains to come off. Improperly installed chains can cause damage to the vehicle. Drivers from time to time drive on dry roads with chains causing the vehicle to slide when braking. During cold and freezing weather conditions, a driver may elect not to put on chains because of the effort and time required to install standard snow tire chains. Standard snow tire chains can come loose and on occasion wrap around the axle. This method reduces the amount of time the vehicle operator spends outside the vehicle, reducing traffic fatalities and other safety concerns associated with the lengthy stays outside the vehicle in inclement weather. The apparatus allows the operator to manually engage or disengage tire chains in one minute or less.
There are other automatic tire chain devices, however the majority of these devices require motors or pneumatic braking systems and are cost prohibitive for most independent commercial truck operators. These motorized and pneumatic systems age and leak air, resulting in the unit not returning to a complete disengaged position. The result of this aging is dragging chains. At speed the dragging chains run over by the tire destroy the unit. Shearing off metal and resulting in the loss of the chain wheel. This apparatus is binary, engaged or disengaged, solving the issue of dragging chains. Other devices require the motorist to be in motion when attempting to deploy the automatic chain system. This apparatus can be engaged when a vehicle is motionless or stuck providing instant traction. This apparatus is designed for quick engagement and similarly quick disengagement on any vehicle. This invention provides the motorist a simple, reliable, convenient, cost-effective method of deploying tire chains on hazardous streets and highways without exposing themselves for prolonged periods of time to weather and risk of accidents. The apparatus eliminates all of the hassle and difficulty associated with putting on standard snow tire chains. The motorist manually lowers and locks the apparatus handle to engage the tire chains. Contrastingly, the motorist unlocks and raises the handle to disengage the tire chains.
In one embodiment, the apparatus handle in a manually lowered lock position, including a plurality of levers and springs, locks the chain wheel to the inside wall of the vehicle tire. When the vehicle is in motion the chain wheel engaged with the inside surface of tire wall will rotate, throwing sections of chain under the tire.
In another embodiment, the apparatus handle in a manually raised unlock position, including a plurality of levers and springs, unlocks the chain wheel disengaging from the inside wall of the vehicle tire. When the vehicle is in motion the chain wheel disengages and releases chain sections allowing a plurality of springs and levers to lift up the chain wheel to an unlocked disengaged position.
The foregoing and other features of the invention are hereinafter described in greater detail with reference to the accompanying drawings.
