Description
FRAMELESS SPECTACLES OR SUNGLASSES BACKGROUND OF THE INVENTION This invention relates to spectacles or sunglasses and more particularly sunglasses of the frameless type.
Many different types of spectacles or sunglasses have been used in the past. Generally such sunglasses comprise a metal, plastic or even wooden frame which is generally foldable. Glass or plastic transparent lenses are secured within the frames so that the lenses are interposed over the eyes where the glasses are placed on the wearer's face. The glasses are generally tinted to filter out unwanted light rays.
Such conventional sunglasses are generally heavy and, therefore, provide some degree of discomfort to the wearer. Recently, a type of unstructured plastic glasses with various tints has been introduced in which a strap extending around the back of the head is used to hold the glasses in place. The strap, however, presents complications to the use of such glasses.
There is a need for lightweight, inexpensive and easy-to-use sunglasses or spectacles. SUMMARY OF THE INVENTION
In accordance with the present invention, sunglasses or spectacles for use in protecting a person's eyes comprises an elongated, transparent sheet formed so that in its unstressed state it assumes a roll-like shape and when unrolled it tends to roll back upon itself. The sheet includes a temple section on each end, a nose bridge section and an eye section located between the nose bridge section and each respective temple section. The nose bridge section is arranged to fit over the wearer's nose to properly align the sheet so that the eye sections extend in front of the wearer's eyes. The temple sections are arranged to exert pressure (as a result of the sheet tending to roll up) against the wearer's temples to hold the sunglasses in place. The sunglasses or spectacles are lightweight, inexpensive and will return to a roll configuration for ease of storing when not in use. The sheet may be tinted or provided with a layer of sunscreening material for filtering out the unwanted light rays.
The features of this invention, both as to its organization and operation, will be best understood from the following description taken in conjunction with the accompanying drawings in which like parts are given the same reference letters throughout the several figures. BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a perspective view of a sheet of transparent material which, when formed into a flexible roll with memory, provides frameless sunglasses or spectacles in accordance with the present invention;
Figure 2 is a perspective view of the sheet of Figure 1 in a roll-lik configuration; and
Figure 3 is a perspective view of the sunglasses or spectacles of th present invention in place on a person's face.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, the .sunglasses or spectacles of th present invention comprise an elongated, resilient, transparent sheet 1 having a nose bridge section 12 and a pair of eye sections 14 and 1
' disposed on either side of the nose bridge section. Temple sections 18 an
20 are formed on the ends of the sheet 10 for engaging the temples of th wearer to hold the sheet 10 in place on the wearer's face as will b explained in more detail.
The sheet 10 is formed into a roll-like shape (in an unstressed state depicted in Figure 2 so that the sheet has memory and will tend to wra around itself and return to the roll shape. The sheet 10, when unrolled an placed upon a person's face as illustrated in Figure 3, will generally follo the contours of the wearer's face with the nose bridge 12 serving to align th sheet with the eye sections 14 and 16 extending in front of the wearer's eye and the temple sections applying an inward pressure against the wearer' temples to hold the glasses or sheet 10 in place. The pressure applied b the temple sections, while sufficient to normally hold the glasses in place, i insufficient to cause discomfort to the person wearing the glasses.
The sheet 10 may conveniently be cut (e.g. by a die) from a roll sheet of a suitable transparent (e.g. thermosetting) plastic such as Mylar® ( trademark of the Dupont Corporation) having an appropriate thickness, e. 700 gauge or 7 millimeter (mm), to cause the temple sections to appl
sufficient pressure to the wearer's temples to hold the glasses in plac without causing discomfort. A layer, such as a sheet of a suitable tintin material, may be added to the Mylar® sheet to provide the desired color shading. For example, I have found that a sheet of Scotchtint® (a tradema of the 3M company) of a suitable color may be secured to the Mylar® by th self adhesive on the Scotchtint®. The combined sheet of Mylar® an Scotchtint® may then be formed into a roll as shown in Figure 2 and heate (e.g. in air or water at a temperature of about 60°C) for a sufficient amount time (e.g. 2-4 minutes) to cause the sheet to be set. When the heat removed, the sheet will return to the roll-like shape with a memory explained above.
There have thus been described novel frameless sunglasses spectacles which are light in weight, inexpensive, convenient to wear a simple to store. Various modifications will become apparent to those skill in the art, without involving any departure from the spirit and scope of invention as set forth in the appended claims.
Claims (12)
