BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of protective clothing, and more particularly to a protective leg sock.
2. Description of the Related Art
As can be seen by reference to the following U.S. Pat. Nos. 5,005,215; 5,031,247; 5,170,503; 5,173,967; and 5,570,470, the prior art is replete with myriad and diverse protective leg coverings.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient and practical protective leg sock suitable for use when operating a flexible line weed trimmer, such as a “WEEDEATER” trimmer. When using a weed trimmer, there are two final results: a neatly trimmed yard; and legs and shoes that are completely covered with grass, weeds, some poisonous oils, dust and dirt.
This not only ruins the operator's jeans, socks and shoes, but numerous people wear shorts while using a weed trimmer and contract problems with poison ivy, poison oak and other allergies associated with weeds and pollen. Just trying to brush off or clean up clothing or untying shoes are very easy ways to become contaminated.
As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved protective leg sock and the provision of such a construction is a stated objective of the present invention.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the present invention provides a protective leg sock suitable for use when operating a flexible line weed trimmer. The sock includes a tubular leg enclosing portion that has an upper open end that pulls up to just above the knee, and a lower open end that flares out to cover the front top portion and the rear heel portion of the user's shoe. An elastic ring encircles the tube above the lower open end to engage the ankle area and prevent material from entering from the bottom. A cord and spring biased barrel closure secures the tube to the leg just above the knee, and grommets on each side of the tube below the upper end provide ventilation. The sock is preferably made from four mil, diamond embossed, tubular plastic film stock.
