Abstract

An eyeglass temple (9) construction is provided that substantially reduces and eliminates slippage of the frame (2) on the nose of the wearer by providing a weight (15) of one-thirty-second to one ounce attached to the rear part (13) of the temple which extends behind the wearer's ears at an angle of at least 55 from the plane formed by the straight section of the temple emanating directly from the eyeglass bridge (6).

Description

EYEGLASSES TEMPLE CONSTRUCTION

SPECIFICATION

BACKGROUND OF THE INVENTION

Field of the Invention. This invention deals basic¬ ally with spectacles and eyeglasses and, more particularly, with the construction of eyeglass temples.

Prior Art. One problem commonly incurred by all users of eyeglasses is that of slippage. This problem becomes particularly acute if the user is active or wearing his eyeglasses in humid weather. Most of the proposed solu¬ tions to this problem deal with the addition of non-skid surfaces, gripping devices and other various structural arrangements of either the eyeglass bridge or temple. Other solutions have proposed the use of weights at the ends of the temples; for example, see U.S. Bidgood Patent 3,768,892, issued October 30, 1973, and entitled "Eyeglasses With Counterbalanced Temple Pieces"; U.S. Bidgood Patent 3,953,114, issued April 27, 1976, and entitled "Cushion Retaining Means For Eyeglasses; and U.S. Pettersson Patent 1,854,060, issued April 12, 1932, and entitled "Spectacles".

However, in all of the prior art samples recited, either the proposed solutions are uncomfortable to the wearer, do not satisfactorily prohibit the slippage of the eyeglasses on the wearer's nose, or are unsightly. OBJECTS OF THE INVENTION

Therefore, it is an object of this invention to provide an eyeglass temple structure that effectively prevents slippage of the glasses on the wearer's nose.

Another object of this invention is to provide an eyeglass structure which is comfortable to the wearer and does not slip on the wearer's nose.

Other objects and advantages of this invention will become apparent from the ensuing descriptions of the invention.

Accordingly, an eyeglass structure is provided having a bridge to which are connected lenses with temples ema- fro either end of the lens frames and extending over and around the ear with the lower portion of the temples being at an angle of at least 55° from the plane formed by the straight section of the temple and provided with weights. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 is a pespective side profile view of one embodiment of the eyeglasses of this invention in position on a wearer's head.

Figure 2 is a cross-sectional view taken along lines 2-2 of Figure 4

Figure 3 is a cross-sectional view taken along lines 3-3 of Figure 4.

Figure 4 is a top perspective view of one embodiment of the eyeglasses. PREFERRED EMBODIMENTS OF THE INVENTION

Referring to Figures 1 and 4, eyeglasses 1 comprise conventional lens frames 2 and 3 which hold lenses 4 and 5 respectively, and are connected together by a typical bridge or nose piece 6. Hingedly attached in a convention¬ al manner at either ends 7 and 8 of frames 2 and 3 are temple members 9 and 10.

Each temple member comprises a straight section 11 which extends outward from frames 2 and 3 and over the wearer's ears 12 and a rear section 13 which is bent down¬ ward from section 11 at an angle "A" of at least 55° from the plane 14 formed by straight section 9 as more clearly seen in Figure 2. Angle "A" is preferably between 60° to 80°, and more preferably between 70° to 80°.

Rear section 13 contains a weight 15 located in the end area 16 of rear section 13. Weight 15 can be con¬ structed from lead or other similar dense materials and,

- \- HE

OMPI for appearances, preferably, is enclosed in plastic 17. Preferably each weight 15 will be between one-thirty- second to three-quarters of an ounce, and, more prefer¬ ably, about three-eights of an ounce for heavier frames and about one-eight of an ounce for lighter frames.

Applicant has found that slippage of bridge 6 on the wearer's nose can only be prevented if weight 15 is posi¬ tioned at rear area 16 which is located at angle "A" of at least 55°. At a lesser angle, weight 15 actually increases slippage in many instances such as when the wearer tilts his head downward. Also at the preferred angle, no additional device or gripping means is necessary to prevent slippage. Furthermore, provided that each weight does not exceed one ounce, at the preferred angle, the amount of weight added is not only not noticeable to the wearer, but actually appears lighter because of the better balance which eyeglasses now achieve on the face of the wearer. In particular, the balance point 17 on eyeglasses has been extended to a position 18 on temples 9 and 10. The exact point of position 18 will depend on the structure and weight of frames 2 and 3, lenses 4 and 5, temples 9 and 10 and weight 15. By extending balance point 17 further away from ends 7 and 8, eyeglasses 1 will rest more stably on the wearer's nose and ears.

There are, of course, other various modifications of the temple structure included within the scope of this invention as defined by the following claims.

Claims

CLAIMSWhat I claim is:

1. Eyeglasses to be worn by a person having ears which comprise:

(a) a lens frame to which is attached lenses; and

(b) two temple members hingedly attached to each side of said frame, respectively, each of said tem¬ ples comprising a straight section extending outward and over said person's ear and a rear section attached to said straight section at an angle of at least 55° from said straight section, each of said rear section having a weight of one ounce or less attached thereto.

2. Eyeglasses according to Claim 1 wherein said preferred angle is between 60° and 80°.

3. Eyeglasses according to Claim 1 wherein said rear section is adjacent to said ear's back side.

4. Eyeglasses according to Claim 2 wherein said weight is between one-thirty-second and three-quarters ounce.

5. Eyeglasses according to Claim 4 wherein said weight is three-eights of an ounce.
