GB2530009A - An Improved Forehead And Eyebrow Spectacle Structure - Google Patents

Abstract

An adjustable spectacle structure comprises a head band 4 attached to a member 2 which supports a pair of spectacles. A second member 1 is attached by hinges 11 or may slide through fasteners 9. Both members contact the forehead of a wearer, the lower member 2 sitting just above the eyebrows, with the other at mid forehead with a space between the two members. A decorative item may be fitted between the two members.

AN IMPROVED

FOREHEAD AND EYEBROW SPECTACLE STRUCTURE

INTRODUCTION

PURPOSE AND BACKGROUND

To create an improved type of spectacle structure with a more secure and comfortable configuration than prior models of this type of spectacle which did not need to contact the nose in any way.

Such earlier models which this applicant pioneered had many various patents granted in many different nations. This earlier models were designed to fit the human head appearing as a headband structure and fitting just at or adjacent the eyebrows and may be counterbalanced by weights at the posterior tip ends of the temples.

Description

The drawings on pages 6 to 9 of this application illustrate various views of embodiments of the improved structure featuring additional contact with the mid forehead cranial supraorbital process eyebrow area by means of an upwards extension from the sides giving a cosmetically attractive effect of a third large eye on the forehead.

The upper band I and lower 2 may be connected with a very thin and flexible geometric design 10 figure 2 such as a circle oval, or any other shapes in order to provide increased surface area contact on the mid forehead. This central forehead large eye or boat like opening provides a space for geometric figures or artistic decorative designs within it, an optional styling fashion feature. The large oval or eye shape shown and described could be altered without affecting the functions described.

The upper forehead contact member 1 May be an upside down version of the lower member 2. Member 1 may or may not be hinged and may slide forwards or backwards through fasteners 9, depending on the amount of the wearer's forehead angle from vertical. This angle or slope does not vary to any great degree in females as much as in larger male heads with thicker supraorbital processes larger, greater eyebrow overhangs and more vertex distance of the lenses from the wearers eyes.

This sliding action is possible since bands 1 and 2 are joined at the forehead sides by clips 9 and also joined by the soft plastic covers of the temple members 4 as in figure 11. Member 2 below is fixed to fastener 9 whereas member 2 may pass slidably through said fastener 9. Both 1 and 2 may be fixed with 1 directly above 2 and no adjustment feature but then more than one model may be needed for forehead slope variations.

Two hinges on each sidell will be needed for convenient folding for insertion into spectacle cases if both 1 and 2 are housed in the temple members 4. Figures 7, 10, and 11.

In figure 6 the lower member 2 continues back to the tip end counter balance. The upper member 1 will end at the last inch or so of the temple posteriorly to allow for a rearward sliding action adjustment. If folding is required then hinges 11 figure 6 are to be provided on member 2.

Fig.11 shows cross sections with member 1 ending before the counter balance.(4A, 4B, & 4C). Hinges may be used in the lower members only if there is a sliding tab 6 on the upper member 1 see tab 6 figures 4, 6 and 9. Then only member 2 with a hinge 11 on each side in the area below the tab will continue on posteriorly through the soft side piece tubing to the tip end counter balance as in figure 6.

The addition of an upper member as in this application for patent represents is the structure illustrated in all figures. The device cannot not move up because of the lower member 2 which may be worn by suspending it just above the nose in the profile space between it and the overhanging eyebrow Figures 1, 2, 3 and 5. Also it cannot move downwards because of the firm forehead contact above by member 1.

The result is a very secure non slip and comfortable feeling for the wearer. The material used may be of springy metal being very thin on the order of in the case of stainless steel or titanium about six tenth of a millimetres plus or minus three tenth varying with the width required.

Certain springy plastics could be injection molded with increased varying different thicknesses compared to metal, depending on the type of plastic being used.

Adjustments if needed are simple, being accomplished with a sliding action by moving the upper member 1 forwards or posteriorly as required inside of the sidepieces by pulling forward at the central forehead portion or by pulling or pushing posteriorly on the tab 6 of figure 6 or 9 depending on which model is used.

Skin prespiration and normal skin oils are the primary causes of slipping for all traditional front heavy nose contacting spectacles. These two factors however actually help to make this device work better.

The increased contact area with the forehead and brow skin which is normally moist and oily makes this device work more efficiently because of surface tension which will even hold a metal coin in place on the forehead without slipping or falling off. The increased contact area added by the upper member 1 is an added reason for such a comfortable fit. The increased lifting power enables this device to easily handle the extra weight of subnormal visual aids or the newer Google glasses presently being developed.

Figure 8 illustrates an optional further addition 12 which makes forehead contact still higher for both an optional decoration and as a method of increasing skin surface contact as above described. It may be larger or smaller than illustrated and be more than one with possibly other different geometric or designer shapes to accomplish the greater skin contact size higher on the forehead. Altering shapes or the number of shapes provided affects the fit only by increasing or decreasing the amount of skin contact. Larger configurations would increase surface tension more than smaller ones and may be even higher or the forehead. 4.

Page 11 Figure 12 illustrates a basic simple model with no counter balance, basic metal with a thick plastic coating, no adjustable features with members 1 and 2 being fixed, a fixed clip 7 with flip up or fold back features containing a round shaft connecting the lenses. Fasteners 9 holds members 1 and 2 together as above explained but are located as shown by 9b figure 2 further from the head than 9a figure 1.

From a top view fasteners figure 9. 9b would be located just posterior to 9 where 1, and/or 2 bend outwards before the second bend going back to hinges 11.

Reference Number Key 1. Upper member 2. Lower member 3. Spectacle lens rims and bridge 4. Temple sidepiece member 5. Metal Tip and or counterbalance 6. Tab for upper member 1 anterior-posterior sliding adjustment located just above the hinges of lower member 2 7. Connecting double swivel clip permitting tilt angle adjustments of the spectacle lenses (pantoscopic angle) and or vertex distance from the eyes to prevent long lashes from touching lenses. Figure 7. The shape of this connecting clip may be different than illustrated herein depending on the type of connection required.

8. Optional decoration 9. Clip connecting the fixed lower 2 and the moveable sliding upper 1 together as one adjustable working unit.

10. Optional decorative and functional design or shape to further increase surface tension of the skin. It may be of another shape and more than one.

11. Hinge on lower 2 and upper 1 or on only the lower member 2 if a tab 6 is used.

12. Optional decorative and functional geometric or designer shape or shapes attached above and secured at the top of member I if desired for extra holding and surface tension. These may be bent or angled if necessary for better forehead contact if needed. The location of any figures above the upper member provides contact even higher on the forehead and in an area heretofore which has been inaccessible. This location by this patent if granted could be very popular in India for forehead jewellery as well.
