Description
Background of the Invention
1. Field of Invention
The present invention relates to objects designed to keep a pair of eyeglasses afloat in the event they are accidentally dropped into water. It also relates to devices designed to enable easy removal or application of eyeglasses, while also providing retention of the eyeglasses on the wearers chest between periods of use.
2. State of the Prior Art
Various types of floats for eyeglasses, or floatable eyeglasses themselves, have been advanced which keep the eyeglasses afloat in the event they are dropped into water. Also various types of retainers have been advanced which retain the eyeglasses on the wearers chest when not in use. Both of these type devices work well for their purposes, but none of them combine a primary purpose of flotation, with a secondary purpose of retention.
U.S. Pat. No. 3,711,190 illustrates a float for spectacles which is a blow molded air cell, having molded loops which are threaded on the temples of a pair of spectacles. Similar devices are illustrated in U.S. Pat. Nos. 3,038,375 and 3,390,938.
U.S. Pat. Nos. 3,740,124 and 3,517,989 illustrate floatable spectacles.
U.S. Pat. No. 4,133,604 illustrates a head band comprising an elastomeric, fabric covered stretch band made adjustable by sliding the temple pieces of eyeglasses into tubular members formed from the end portions of a flat band. This head bands primary purpose is to retain the eyeglasses to the wearers head, when in use. Secondary purposes utilized by the head band are for neck retention when not in use and as a flotation device in case the eyeglasses are dropped into a body of water.
U.S. Pat. No. 2,481,946 illustrates a neck retainer for spectacles having a small tubular member attached to a fabric strap which fits around the neck, and holds the glasses on the chest of the wearer when not in use.
U.S. Pat. No. 4,541,696 illustrates an eyeglass retainer comprising a tubular elastic knit cord made adjustable by sliding the temple pieces of eyeglasses into the tubular ends of the cord.
Brief Summary of the Invention
The present invention is an eyeglass retainer primarily used for floating eyeglasses in the event they are dropped into a body of water. However, the device may be utilized to retain the glasses in place around the wearers neck when the glasses are not in use.
The device comprises an elongated, solid cord. The cord is made from a flexible, buoyant material. This cord is covered with tubular fabric. Two resilient ovals are crimped directly to each end of the cord by clamps. Slipped onto each of the clamps is a small tubular piece of buoyant material. A small resilient spacer is then slipped onto each oval which forms a small opening in which the temple of the eyeglasses are force fed into, forming a snug fit on the temple. However, these spacers may be removed in the event wide templed eyeglasses are used, utilizing the original pair of ovals to slip the wide temples of the eyeglasses into.

Detailed Description of the Drawings
Referring to FIG. 1, a pair of eyeglasses as shown generally at 5 has lenses 6, a main frame 7 for the lenses, and bow pieces or temples, indicated at 8, attached to the main frame of the eyeglasses by hinges in the normal manner. A floatable eyeglass retainer made according to the present invention illustrated generally at 9 is slipped on the temple pieces 8 of the eyeglasses. The eyeglasses are shown floating in water illustrated generally at 10.
Referring to FIGS. 2 and 2A, these illustrate enlarged perspective views showing the assembly of one end of the floatable eyeglass retainer. The retainer preferably comprises an elongated, flexible cord 11. The cord 11 also comprises a buoyant elongated, solid rod 11A which is also flexible. The cord also comprises an outer tubular fabric covering 12. Buoyant materials for such cord 11 are closed cell neoprene foam or closed microcellular cross link polyethylene foam. Still other suitable materials for the invention will become evident and is not limited to the before mentioned material.
Referring to FIG. 2, at each end of the cord 11 a resilient oval 13 is attached directly to the cords end 14 and to the tubular fabric 12, by use of a clamp 15.
Referring to FIG. 2A, the clamp 15 should be affixed whereas approximately one-half of the resilient oval 13 is left out of the clamp 15, as shown only in FIG. 2A. After each clamp 15 is affixed to the cord 11 and tubular fabric -2, a small tubular piece of buoyant material 16 is slipped over the resilient oval 13 and onto the clamp 15. A small resilient spacer 17 is then slipped onto each oval 13.
Referring to FIG. 3, shown is an enlarged side elevational view of one end of the floatable eyeglass retainer, shown generally at 9. After the small resilient spacer 17 is slipped onto each resilient oval 13 a small opening 18 is formed in which the temple piece 8 of the eyeglasses is force fed into.
Turning now to FIG. 4, illustrated is a perspective view of a pair of eyeglasses, shown generally at 5, with a wide temple piece 8. Attached to the eyeglasses temple 8 is one end of the floatable eyeglass retainer, shown generally at 9. The eyeglass retainer is excluding the small resilient spacer 17, shown in FIGS. 2A and 3, in order that the opening formed by the resilient oval 13 can accept the wide temple 8 of the eyeglasses.
