Description

MEMBER OUTS TAKES DOWN DOWN ON A GOGGLES SUPPORT BACKGROUND OF THE INVENTION The present invention relates to an improvement in spectacle frames, and more particularly to a pull-down member attached to a spectacle frame to hold the spectacle frame loosely but comfortably against the wearer's face. It is very inconvenient when the glasses slide down the nose of the user and have to be adjusted continuously on the face of the user. This is not only inconvenient, but particularly dangerous when it comes to safety glasses. If the safety glasses are not placed continuously on the nose of the user to adequately protect the eyes, an accident or something worse may occur due to the flying objects and the waste, because the eyes were not properly protected. This problem of slg glasses down the nose of the user is a very common presentation in warm weather, but also occurs when the user is involved in a physically demanding activity. Under these circumstances a user is more vulnerable to accidents, even when wearing safety glasses, if the safety glasses are not properly placed on the user's face and are not held in that position. The slg of the glasses from the nose of the user can also counteract the positive effect of the ultraviolet protection offered by many spectacle lenses. Eye care professionals, as well as eyeglass wearers, are concerned about the harmful effects that ultraviolet radiation can have on the eyes, and in particular, their possible link with cataracts and other eye diseases. Most optical laboratories offer ultraviolet protection for your lenses. However, if the glasses slip as little as a quarter of an inch (approximately 6 millimeters) down the user's nose, a significant amount of ultraviolet radiation could be incident on the eyes. If the glasses slide as much as 2.54 centimeters down the nose, then almost all of the ultraviolet protection provided by the lenses is ineffective, and virtually all of the ultraviolet light hits the eyes. Approximately 60 percent of the population that wears glasses wear multifocal lenses, such as bifocals, trifocals, and so on. The position of the segments of these multifocal lenses is critical, and varies with the type of lenses, as well as with the position of the user's eyelids in relation to the frame of the lenses. If the user's glasses slide approximately 6 millimeters, the position of a pair of bifocals can be shifted 100 percent from where the segments should be placed. When looking through incorrect segments of multifocal lenses, an individual can not only have an inconvenience, but could be injured due to impaired vision. Also, the displacement of glasses used by athletes presents problems, especially with regard to specialized sports eyewear for fishermen, cyclists, or golfers. With respect to each of these sports, as well as many others, individuals complain about their frames falling or slg down their noses. Fishermen often lose their glasses in the water, golfers can not tolerate the slightest movement of their glasses and cyclists do not like to risk moving their hands to push their glasses back to their position. Accordingly, there are numerous and very real problems associated with the displacement of the glasses from their proper position on the user's face. To rectify these problems, devices such as elastic or elastic bands are attached from one end of a goggle holder to the other end, to hold the glasses on the user's face. However, these elastic bands are often uncomfortable, and often cause the glasses to rub against the user's nose and ears, causing irritation. Also, it is very common that, when one wishes to use these bands or elastic straps, they can not be found or located, because they are not a permanent accessory for glasses. Since these straps or elastic bands are relatively inconspicuous, they are easily lost or misplaced at a time when they are most needed. Although it is not uncommon to see athletes and workers who use these elastic bands, however, there are many inherent drawbacks with their use. The problem of the sliding of the glasses has been solved for many years by the use of what is commonly known as "cable supports" or "corrugated supports". These supports simply wrap around the ear. Originally, these supports were made of metal, but in the most recent years, they have been covered with plastic or silicone, and in some applications they are completely made of plastic. However, the problem with cable supports is that most eyeglass users find them uncomfortable. The reason is simple. The curvature of the cable supports does not match the curvature of the user's ear. Individuals not only have ears of different sizes, but ears of different shapes. Also, the shape of the ear is not a smooth curve. Since the curvature of a cable support is fixed, it can not easily be contoured to the curvature of a user. Also, since the cable supports "wrap around" the user's ear, they tend to exert pressure in some areas, and become loose in other areas. Therefore, cable supports are not an adequate solution to this problem.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the aforementioned problems and drawbacks associated with the elasticised bands and other elements used to retain the glasses on the face. Another object of the present invention is to provide a device that pulls down, that is permanently attached to the frame of the glasses, and that comfortably retains the frame on the face of the user. A further object is to provide a member that is pulled down, that merely touches the user's ears, and that does not wrap around the ears. Still another object of the present invention is to provide a pull-down member, having a series of positions relative to the eyeglass frame, to comfortably accommodate the member that is pulled down for a universe of users, due to the selectivity of the available positions. In accordance with the present invention, the foregoing and other objects and advantages are achieved by goggles having a lens frame and a pair of supports to which an elongated member that is pulled down is attached. The pull-down member is pivotally and zipped to a distal end of each end piece of each support. The member that is pulled down is oriented in any of a series of pivoted positions relative to the end piece, to provide the eyeglasses with a comfortable fit. In one embodiment of the present invention, the downwardly pulling member has a edge with a plurality of notches therein, and an elongated appendage with a contoured edge adapted to rest against the wearer's ear of the glasses. A forcing element is housed inside each end piece, and is placed therein so as to be able to be coupled in a rack fashion with the notched edge of the member being pulled down, and thereby provide the member that is pulled towards down a series of pivotable positions with respect to the end piece.

In a second embodiment of the present invention, the elongated member that is pulled down has an opening defined by a series of teeth, and a slotted bolt having a complementary series of teeth along an external surface thereof, which is it pivotally uses the member that is pulled down on the end piece of each support. The toothed opening of the downwardly pulling member engages with the toothed outer surface of the slotted bolt, such that, by applying an appropriate force, the elongated member that is pulled down can be pivotably mounted and in a pivotal manner. rack in any of several previously determined positions in relation to the end piece. The pull-down member of the present invention will typically be attached to a distal end of the end piece of each eyeglass holder. Other features and advantages of the present invention will become clearer from the following description of the invention, which refers to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, in which like numerals indicate like elements, in Figure 1, a pair of eyeglasses 1 is shown comprising a lens frame 2 for conventional or safety lenses, and a pair of lenses. supports 3 pivotably attached to a proximal end 4 with the lens frame 2. At its distal end 6, each support has an end piece 5 which is configured to extend behind an ear of the user of the eyeglasses 1. An elongated member that pull down 10 is pivotally and zip-linked to each end piece 5 at its distal end 6. The pull-down member 10 is typically made of a soft and flexible material, such as a soft plastic, and it can be placed at different angles in relation to the end piece 5, to comfortably adjust the glasses 1 to the user. Although the member that is pulled down 10 touches a small area of the user's ear, it does not wrap around the ear, which can be uncomfortable. The pivotable placement of the pull-down member 10 around the distal end 6 is shown in general in Figure 1, wherein the pull-down member is shown at maximum angular displacement with the end piece 5 in the position A, and at an intermediate angular displacement from the end piece 5 in position B.

The pull-down member 10 can also pivot pivotably within a recess 12 in the end piece 5 when the pulling member is not used downwardly. When received in recess 12, the member that is pulled down 10 is received completely therein, but nevertheless, may rest on the user's ear on one edge thereof. An arcuate recess 14 may be formed in recess 12, to assist the user in holding the limb that is pulled down when placed within recess 12. Referring to Figure 5, the member that is pulled down 10 includes a disc-shaped core 16 attached to an elongate appendage 18 which is the portion of the member that is pulled downward 10 which is intended to rest against the ear of the user. Typically, the elongate appendage 18 is of a soft and flexible plastic, and the core 16 is made of a harder or more durable plastic, such as polycarbonate plastic. A curved recess 20 (Figure 2) can be formed in the elongated appendage 18, to accommodate the tip of a user's finger, for easy displacement of the member that is pulled downwardly 10 around the distal end 6 of the work piece. end 5. The core 16 has a centrally disposed opening 22, and an outer edge 24 to which the elongated appendage 18 is attached. A core appendage 26 extends from the outer edge 24, and is received in the elongated appendage 18, to better secure the core 16 to the appendage 18. The outer edge 24 also accommodates a series of notches 28 on a portion thereof, which in part accounts for the positions by which the pulling member 10 is moved angularly from the end piece 5. At the distal end 6 of the end piece 5, a disc-shaped opening 30 is formed to accommodate the core 16 of the pull-down member 10. An opening 32 (Figure 3) extends through the distal end 6 in a direction transverse to the disc-shaped opening 30. The transverse opening 32 of the distal end 6 is aligned with the central opening 22 of the core 16, such that a pin 34 can be instantly adjusted through the openings 32 and 22, for retaining the pull-down member 10 at the distal end 6. Extending along the longitudinal axis of each end piece 5, there is a channel 36 (Figure 4) extending to the opening in disk shape 30 at the distal end 6 of the end piece 5. Hosted inside the channel 36, there is a coil spring 38, which is compressed against a ball member 40 positioned at the end of the channel 36, to abut against the edge 24 of the core 16, and thus adapt to engage respectively with the notches 28. Accordingly, by means of the coil spring 38 and the ball 40, a forcing pressure is applied to the core 16 in the edge 24 and in the notches 28, such that, by applying a pivotable movement to the downwardly pulling member 10, the downwardly pulling member can be angularly displaced in different positions relative to the end part. 5, when the ball 40 is forced into the notches 28. In other words, when the ball member 40 is forced into a notch 28 of the core 16, the member that is pulled down is secured in an angular position in relation to the end piece 5, until another pivotable movement is applied to the downwardly pulling member 10, to cause it to move angularly to another position in relation to the end piece 5. A second embodiment The present invention is disclosed with respect to Figures 6 to 9, wherein the like numerals indicate like elements in relation to the first embodiment. Referring to Figures 6 and 7, the second embodiment of the pull-down member is designated by the numeral 100, and includes an elongated appendage 18 attached to a bank 102 of a core 104. The core 104 generally has a disk shape. , and the similar core 16 of the first embodiment typically becomes a hard plastic, such as a polycarbonate plastic. Also as the core 16, the core 104 includes an appendage 26 that extends into the elongated appendage 18. An opening 106 (Figures 6 and 8) is centrally disposed in the core 104, and is defined by a series of teeth 108. A disc-shaped opening 30 is formed in the distal end 6 of the pull-down member 5 (Figure 7), in order to accommodate the core 104 between two spaced disks 109. An additional opening 110 is placed transversely to the opening 30, and extends through each of the disks 109. The central opening 106 of the core 104 is aligned with the opening 110 of the distal end 6, and a slotted pin 112 (FIG. 7) is placed in the opening 110, so as to retaining the pull-down member 100 at the distal end 6 of the end piece 5. Referring to Figures 7, 8, and 9, the slotted pin 12 includes a flattened portion 114 with two spaced legs 116 extending from the portion 114. The legs 1 16 have a cross-sectional configuration that is generally semicircular (Figure 8). Extending along an outer surface 118 of each leg 116, there is a series of teeth 120 which can be engaged with the teeth 108 defining the central opening 106 of the core 104. With the teeth 108 of the central opening 106 engaging the teeth 120 of the slotted pin 112, the pull down member 100 is retained in an angular position relative to the end piece 5. However, if the user pivotably moves the pull down member 100, the teeth 108 that are the teeth 120 are thus uncoupled from the teeth 120, since the pivotable force applied to the pull down member 100 will cause the legs 116 to collapse towards each other, thereby disengaging the teeth 120 from the teeth 108. Once the application of this pivotable force is stopped, the teeth 120 will engage with other teeth 108, with the result that the pull down member 100 moves to Another angular position relative to the end piece 5. Accordingly, by this, the pull down member 100 can be pivotally and rack-mountable relative to the end piece 5. Although the present invention has been described in relation to the particular modalities of the same, the experts in this field will be able to see many other variations and modifications and other uses. Therefore, it is preferred that the present invention is not limited by the specific description herein, but only by the appended claims
