ABSTRACT:
BACKGROUND OF THE INVENTION
The field of the invention is assemblies for attaching sunglasses to a cap.
People often wear sunglasses and baseball caps while participating in sports or other outdoor activities. When these are separate items the problem is where to store the sunglasses when they are not needed.
Several types of sunglass and cap combinations are known in the prior art. My U.S. Pat. No. 5,778,448 discloses an assembly for attaching sunglasses to a cap by means of clamps and hinges which fits onto the sides of a cap bill and adjusts for width of cap bills by means of interlocking teeth. Said device also has a pressure clamp onto the lenses which allows the lenses to be flipped up underneath the cap bill when not in use and to be flipped down for use. Other U.S. Patents which disclose sunglasses and cap combinations include U.S. Pat. No. 5,422,686 to Kelman et al. , U.S. Pat. No. 5,261,124 to Day, U.S. Pat. No. 5,615,413 to Bower, U.S. Pat. No. 5,471,259 to Cahill, No. 5,208,916 to Kelman, U.S. Pat. No. 5,491,841 to Valletta, U.S. Pat. No. 5,987,640 to Ryder, U.S. Pat. No. 5,930,834 to Toovey, No. 5,826,271 to Garrett, and U.S. Pat. No. 5,819,318 to Tse. None of the known prior art discloses the combination of features found in the present invention.
SUMMARY OF THE INVENTION
The present invention is an assembly which allows the sunglasses to be removably attached to the underside of the bill or the inside rim of the cap by fastener means, and also allows the position of the sunglasses to be adjusted by means of a two-part hinging device.
An advantage of this arrangement is that the assembly is more readily adjustable.
Another advantage is that the assembly is concealed and not visible on the front or sides of the cap bill.
Another advantage is that the assembly can be removed and remounted on any size cap.
Another advantage is that the sunglass lenses can be readily removed and replaced.
Still another advantage is that the hinging device allows the user to vertically adjust the lenses up or down, or to adjust the lenses to any position the wearer desires.
