Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, a mold-piece eyeglass structure is created by an optically transparent and resilient monthly veneer. The structure includes a front portion with a pair of juxtaposed generally planar viewing portions joined together by a bridge having a notch to accommodate a person's nose. A pair of temples extend rearward from the outer edges of the corresponding viewing portions of the front, and the spacing width of the temples is at the apex less than or equal to the width of the head of the person wearing the sunglass structure. . The sunglass structure has a low profile and the viewing width is approximately equal to or slightly wider than the width of the temple.

The present invention relates to structures, such as sunglasses, made from molded pieces of optically transparent and resilient material.

'', available sunglasses typically consist of a spectacle frame made of wire or plastic, a pair of tinted lenses held within the frame, and a pair of tinted lenses hinged to each side of the frame. Contains the vine. Although various sizes and shapes have been proposed for sunglasses over the years, there have been very few changes to the basic structure of sunglasses. Although the basic structure of the sunglasses accomplishes its intended purpose, it is fairly complex and expensive to manufacture, as it involves manufacturing and assembling a number of separate parts.

It is true that various proposals have been made to provide molded sunglass frames with an opening in the front for loading tinted lenses. Although these various proposals eliminate the need for a hinge, they still require the assembly of many parts because the eyepiece must be loaded into the frame.

It is an object of the present invention to provide a sunglass structure that is simple in design and easy to manufacture.

Another object of the present invention is to provide a sunglass structure that is both stylish and durable.

Another object of the present invention is to provide a single-dimensional sunglass structure that accommodates various head sizes.

It is also an object of the present invention to provide a sunglass structure that is easy to store and carry when not in use.

The foregoing and other objects of the present invention include a veneer of optically transparent resilient material formed with a front portion having a pair of juxtaposed generally planar viewing portions. This is accomplished in a particularly exemplary embodiment of a sunglass structure. The viewing parts are joined together by a bridge defining a cutout at the bottom that fits a person's nose. The structure also has a pair of temples formed therein, each temple extending from the upper edge of a corresponding viewing portion in the rearward direction of the front portion. The temples are spaced atop and at a distance less than or equal to the width of the person's head so that the elasticity of the material presses the temples against both sides of the person's head to hold the structure in place. There is.

According to one aspect of the present invention, the width of the viewing portion is such that the margin portion is wider than the width of the temple portion, so that the overall sunglass structure has a low profile and an image of a luxury product, and its storage is difficult. becomes easier.

The foregoing objects, other objects, features, and advantages of the present invention will become apparent from a consideration of the following detailed description taken in conjunction with the accompanying drawings.

Referring to the drawing, there is shown a mold piece sunglass structure 4 made of a veneer of optically transparent and resilient material. The material can be colored or dyed to reduce the intensity of light passing through the material. Examples of materials that may be advantageous in the construction of such structures include polymers such as polymethyl methacrylate, polyethyl methacrylate, polymethyl acrylate, butyl methacrylate, amyl methacrylate, and related copolymers. Generally, any transparent, resilient, and sufficiently durable material can be used for the Zanglas structure of the present invention. The material must also exhibit these impact resistance properties required for sunglasses, and must be free of substantial optical distortion in the viewing area (mentioned briefly).

The single-piece sunglass structure 4 includes a pair of juxtaposed generally planar surfaces connected together by a bridge section 20 that defines a cutout on the bottom side of the bridge section 20 to fit the folds of the person wearing the sunglasses. It is formed by a front part 8 having a shaped viewing part 12,16. A temple 28.32 extends rearwardly from the outer edge of the individual viewing portion 12.16. Vine part 28
, 32 are generally parallel to each other, but slightly slightly, as best shown in FIG. It's bent. The separation of the temples 28,32 is selected to be slightly below the width of the average wearer's head.

For structural integrity and ease of manufacture, the front section 8
, the upper edge of the temple 28, 32 and the front part 8, the temple 28
．． The bottom edges of 32 are each shaped to define a generally continuous unbroken line. That is, no sharp breaks or angles are formed between the front part 8 and the temples 28, 32 on either the top or bottom edges of the structure.

The width of the front part 8 is approximately the same as the width of the temple at the point where it is joined to the front part, or is larger in parts of the edges. Advantageously, the width of the front section is between 3/4 inch and 11/4 inch. Furthermore, the upper edge 36 of the front portion and the two edges 40, 44 of the front portion of the temple portion are such that when the structure is placed upside down on a flat surface, contact with that surface will occur only at the upper edge. 36, 40, and 44 to define one overall surface.

Approximately 0 thickness for comfort when wearing sunglasses and to ensure that the sunglasses stay in place
, 31 tyn (1/B inch) of the structure, approximately 32,688 to 36.320 kg/ca (
450,000 to 500,000 p, s,
The elastic modulus of i) is selected.

In the case of the sunglass structure defined above, sunglasses (or safety glasses) are provided which are robust, attractive and easy to manufacture. The structure has a low profile that facilitates storage and provides a premium appearance. The top and bottom edges of the structure are generally continuous, unbroken lines, which facilitates manufacturing while maintaining structural integrity. It should be understood that this is just one example of applying the principles of. Those skilled in the art will be able to devise numerous modifications and alternative structural arrangements without departing from the technical spirit and scope of the present invention.
The following claims are intended to cover such modifications and structural arrangements.
