Description:
EXPANDABLE EYEWEAR WITH SNAP-TOGETHER BRIDGE

TECHNICAL FIELD

The present invention deals with improved eyewear having a snap-together bridge feature,

BACKGROUND OF THE INVENTION

Applicant is the owner of U S Patent No 6,253,388 The invention disclosed and claimed in the '388 patent involved eyewear comprised of a pair of lenses, releaseable connectors connected to respective inner ends of the lenses, a pair of temples pivotable to respective outer ends of the lenses and a rigid strap attached between rear ends of the temples . The strap was taught to be positioned below the lenses so as not to interference with a hairdo or helmet . The inner ends of the lenses wer e taught to be releaseably secured together by the connectors, preferably, magnets . To position the eyewear , the lenses are first separated from each other and pivoted outwardly The strap is then wrapped around the back of a user 's head and the lenses pivoted towards each other and secur ed together 1 in fr ont of the eyes , The lenses wer e taught to be instantly separ able for easily putting on and taking off the eyewear, but they are instantly connectabie for a secure and accurate fit .

Fig, 1 depicts the eyewear' generally disclosed and claimed in applicant's '388 patent Specifically, lenses 10 were shown to be preferably mounted in respective frames 14 which are pivoted to temples 12. Connectors 1 1 are attached to respective inner ends of frames 14 Temples 12 are preferably telescoping for fitting different wearers , As noted, temples 12 were taught to be pivoted to the respective outer ends of frames 14 and include hook portion 16 for hooking around a user 's ears. Strap 13 was taught to be positioned below lenses 10 so as to avoid interfering with a hair do or helmet and preferably springy enough to retain its shape when released, but also flexible enough to be bendable to some extent without breaking. Alternatively, strap 13 was taught to be at the same level as temples 12, but at a loss of some advantages The disclosur e of U S Patent No . 6,253,388 is incorporated herein by reference. Fig 2 depicts as oval 50, the head of a user from a perspective above the user facing straight down thereupon., The major axes of user's head 50 are shown from front to back as 21 and side to side as 22, The '388 patent taught, as a preferred embodiment, the ability to alter the length of the strap/temple pieces in the event the user's head along axis 21 was particularly large to minimize the inadvertent separ ation of the lenses by disengagement of connectors 11.. It was found that if a user had a particularly elongated head along axis 21, normal use of the eyewear could result in lenses 10 separating from one another by inadvertent detachment of connector s 11 which would discour age continued use of such eyewear . However , the former 1 eyewear disclosed by applicant had no way to accommodate users whose heads were particularly wide thus having a dimension along axis 22 which is of considerable proportion.

It is thus an object of the present invention to provide eyewear with a snap connector bridge capable of adjustment along both major axes of a user's head to thus provide such eyewear to a greater segment of the using public .

These and further objects will be more readily apparent when considering the following disclosure and appended claims .

SUMMARY OF THE INVENTION

The present eyewear includes a pair of lenses, a pair of releaseable connector s connected to respective inner ends of the lenses, a parr' of temples pivotally connected to respective outer ends of the lenses and a rigid strap connected between rear ends of the temples Ihe strap is generally U-shaped having substantially parallel legs connected to an ar c-shaped base, the substantially par allel legs being connected to r ear- ends of the temples and when worn, the arc-shaped base extends along the back of a user 's head. The strap at its U-shaped base is provided with a telescoping segment for 1 selectively altering the length of the arc-shaped base for altering the spacing between the strap's substantially parallel legs to adjust the strap for varying widths of a user 's head. The inner ends of the lenses ar e teleaseably secur ed together by connector s In use, the lenses are separated from each other and pivoted outwardly, the strap wrapped around the back of a user's head and adjusted for size The lenses are then pivoted towards each other and secured together in front of the user's eyes The lenses are instantly separable for easily putting on or taking off the eyewear, but they are instantly connectable together for a secure and accurate fit.

DETAILED DESCRIPTION OF THE INVENTION

Novel features which are characteristic of the invention, as to organization and method of operation, together with the further objects and advantages thereof will be better understood from the following description considered in conjunction with the accompanying diawings, in which preferred embodiments in the invention are illustrated by way of example It is to be expressly under stood, however, that the dr awings ar e foi illustration description only and are not intended as definitions of the limits of the invention. Ihe various features of novelty which characterize the invention are recited with particularity in the claims

There has been broadly outlined the more important features of the invention in the summary above in order that the detailed description which follows may be better understood, and in order that the present contribution to the ait may be appreciated There are, of course, additional features of the invention that will be described hereinafter and which will form additional subject matter of the claims appended hereto Those skilled in the art will appreciate that the conception upon which this disclosure is based readily may be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the pr esent invention

Certain terminology and derivations thereof may be used in the following description for convenience and reference only, and will not be limiting For example, words such as "upward", "downward", "left" and "right" refer to directions in the drawings to which reference is made unless otherwise stated Similarly, words such as "inward" and "outward" refer to directions toward and away from, respectively, the geometric center of the device or area and designated parts thereof Reference in the singular sense include the plural and vice-versa, unless otherwise stated

As noted previously, applicant has taught in its U S Patent No. 6,253,388, eyewear 1 which includes lenses 10 mounted in respective fr ames 14. Connectors 11 are preferably attached to inner ends of frames 14. Temples 12 are preferably telescopic for fitting different wearers.. As to this later feature, it is noted that telescoping temples 12 assist a wearer whose head, along axis 21 is laiger than nomial Without this telescoping feature, an attempt to wear applicant's eyewear with snap-together bridge could, and oftentimes does, inadveitently lose connectivity at the bridge r esulting in the lenses separating at 32 as shown schematically in Fig 4 A However, despite the telescoping feature described above, if a person's head is somewhat larger than aveiage along axis 22, inadveitent r elease of connectoi s 32 cannot be avoided .

In turning to Fig. 3, eyewear 30 is depicted in a downwardly facing elevational view. Shown are lenses 31 and 33 releasably from one another' at their inner 1 ends through the use of connectois 32, preferably, a pair of magnets embedded within frames surrounding each of said lenses 31 and 3.3 Temple pieces 34 and .35 pivotally extend from the lenses or their frames 31 and 33, respectively and are connected to generally U- shaped strap 36, the str ap being r igid enough to generally r etain its shape when connectois 32 are released and is spiingy enough to be bendable when flexed and rebound when released .

As noted by arrows 41 and 42 in Fig, 3, temple pieces 34 and 35 can telescope with regard to parallel legs 37 and 38 of U-shaped strap 36 thus extending or contracting the distance between lenses 31 and 33 and the arc-shaped base 39 of eyewear 30 along axis 21 (Fig, 2)

Even with this telescoping featuie, it is very common for lenses 31 and 33 to separate as depicted in Fig. 4A paiticulaily if head 50 is unusually wide along axis 22

(Fig . 2) . To account for this contingency, strap 36 is provided with telescoping segment

60, the details of which will be desciibed hereinafter

In wearing eyewear 30, the inner ends of lenses 31 and 3.3 are pivoted with respect to temples 34 and 35 so that they extend outwardly and substantially as extensions to temples 34 and 35 as U-shaped strap 36 is placed around head 50 of a user . Thereupon, lenses 31 and 33 are pivoted with respect to temples 34 and 35 until connector s 32 releaseably attach the lenses to one another as more fully desciibed in the '388 patent.

However, if head 50 of the user is particularly wide (along axis 22 of Fig. 2), lenses 31 and 33 can separate at opening 51 making the present eyewear impractical . When this is experienced, ends 61 and 62 of stiap 36 at arc-shaped base 39 can be separated from one another in the direction of arrows 43 (Fig.. 3). Ideally, bridge 60 having extension pieces 60a and 60b telescope within strap 36, its position being held through friction or through the use of protrusions 64. Thus, as ends 61 and 62 of substantially arc-shaped base 39 of strap 36 pull apart and away from one another, eyewear 30 shown in Fig 4 A is transformed into eyewear 30 of Fig. 4B enabling the eyewear to ideally fit about head 50 of the user thus preventing the inadvertent disengagement of connectors 32 from occurring.

The above disclosur e is sufficient to enable one of or dinary skill in the art to practice the invention, and provides the best of mode of practicing the invention piesently contemplated by the inventor While there is provided herein a full and complete disclosure of the preferred embodiments of the invention, it is not desired to limit the invention to the exact construction, dimensions, relationships or operations as described., Various modifications, alternative constructions, changes and equivalents will readily occur to those skilled in the art and may be employed as suitable, without departing fiom the true spirit and scope of the invention Such changes might involve alternative materials, components, structural arrangements, sizes, shapes, forms, functions, operational features or the like

Therefore, the above description and illustration should not be construed as limiting the scope of the invention, which is defined by the appended claims.
