TECHNICAL FIELD OF THE INVENTION
The present invention relates to frames for glasses.
In particular, though not solely, the present invention is directed to an eye glass frame that can be worn on the face and then manipulated to wrap around an elongate object, for example, but not limited to, a wrist or arm.
BACKGROUND OF THE INVENTION
Glasses normally have a pair of arms that are hinged from the frame that holds the lenses of the glasses. The purpose of the hinge, at least in part is to allow folding of the arms substantially into the plane of the frame when not in use. Such hinges are often a weak point of glasses frame design.
There are known arms and hinges that are sprung to give some resilience to the hinge and also account for bending out of the arms.
A problem with many glasses, for example reading or sun glasses, is they are not on the face all the time. Often a user will wear them for only brief periods of time, for example when in the sun, or when reading, but will take them off otherwise. In these situations the user must find a location for the glasses once removed. Placing them on top of the head may interfere with hair, or a hat, or they may simply fall off. Hanging them from places allows them to move and dangle about and may be a nuisance or even a hazard. Taking them off and stowing them in a glasses case can be relatively time consuming, especially if they are on again off again, and then requires the user somehow to retain the glasses case separately. In situations where the user takes the glasses on and off regularly there is a risk they may also put them down. Should they do so, then there is a real chance of forgetting them or leaving them behind. The result is they are not easily on hand when needed again, or worse they may become lost.
There is therefore a need for a glasses frame that can be removed and easily stowed either on the person themselves, or an object of theirs, easily repeatably and in the knowledge they are securely retained until they are needed again. Removal, stowing and then removing and applying to the users face should also be easy and not complicated.
In this specification where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.
It is an object of the present invention to provide an improved eye glass frame or to overcome the above shortcomings or address the above desiderata, or to at least provide the public with a useful choice.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments will now be described with reference to FIGS. 1 through 22.
A glasses frame 1 as shown in FIGS. 1 and 2 consists of a first lens holding portion 3 and second lens holding portion 4. Each of the lens holding portions is capable of holding a lens 2. The lens 2 may be any one or more of a prescription lens, sunglass lens, protective lens, cosmetic lens or otherwise. The lens holding portions 3 and 4 as shown are unitary and completely surrounding the lens 2. In other forms they may be multipart and/or multi-material. In other firms they may only partially surround the lens 2, for example they may be screwed or otherwise fasten to the lens 2. The lens holding portions may be made in variety of materials, for example steel, plastic, alloy or composites or other traditional materials. The lens holding portions may be made in a variety of know techniques for example injection moulding for plastic, or stamping or forging for metals.
Between the portions 3 and 4 is a hinge 5. In this case the hinge consists of a double hinge having pivot points 5A and 5B, which are located either side of a nose piece 13. The nose piece 13 connects each of the portions 3 and 4. The hinge as shown has an axis of movement 10 that is perpendicular to the major surface 11 shown in FIG. 3 of the lens holding portions. This surface may be planar or curved; in FIG. 3 it is curved. In other forms of the invention the hinge may consist of only one hinge point, such as shown in FIG. 6. The hinge may be biased to an open or closed position or both. There may also be a locking mechanism for either open or closed position. Friction may also be employed to lock the hinge in the open, closed, or both positions.
Extending from edges 7 that are distant from the hinge 10 are first arm 6 and second arm 8. The arms are at least in part, and in one embodiment completely, made from a bi-stable material. Such a material holds its elongate form as shown in FIG. 1, but when displaced beyond a certain point, loose that form and will revert to another form, for example a curved or curled form, such as shown in part in FIG. 5, where they are shown wrapped about the wrist 9. The displacement is normally out of the plane of their elongate form and may be initiated at any point along their length, including the ends or the middle. The arms 6 and 8 are preferably parallel to each other in the state shown in FIG. 1 and in addition angled or curved toward each other, as shown in FIG. 3. This angling can help them grip the head of a user. In addition there may be a coating on the bi-stable material for comfort, grip, safety, marking, encapsulation, protection or aesthetics. The coating may be a silicone, rubber or similar material. In the preferred embodiment the bi-stable material is a metal, such as, but not limited to a stainless steel, but may also be a plastic, composite or other material. An activated material that retains one form with energy and another with removal of that energy may also be used. The folding, curving or bending of the arms may also be controlled, for example the arms may have parts that prevent folding 14, and parts that allow folding 15 such as shown in FIG. 8. The arms are sized to fit the user's head and also for the size of object they will fold around when in the folded position. The arms 6 and 8 may also be removable as shown in FIGS. 9 and 10. This may allow replacement due to breakage, resizing needs, or change of look of the arm.
The first or unfolded position of the glasses frame 1 is shown in FIG. 1 for example. In this extended format the glasses 1 can be used by a user and placed on their head, for example to read. In a second or folded position or condition the glasses are folded about the hinge 5 as shown in FIGS. 2, 4 and 6. The arms 6 and 8 are allowed also to fold to then retain the glasses 1 to an elongate object 9, such as a wrist or arm as shown in FIGS. 5 and 7.
In one preferred form of the present invention the first lens holding portion 3 and second lens holding portion 4 move about the hinge 5 to lie side by side each other, for example as shown in FIGS. 2, 4 and 6. In this form the axis of movement 10 is substantially perpendicular to the major surface 11 of the lens 2. Shown in FIG. 4 the hinge 5 may be a multi-element hinge by using an additional hinge portion 17 hinged at pivot points 5A and 5B that extends the hinge 5 to accommodate better folding, this may also form the bridge of glasses 1.
In another form of the present invention the hinge 5 (whether single or multiple element hinge) allows the lens holding portions 3 and 4 to rotate and lie one on top of another as shown in FIGS. 11 and 12 with the arms omitted for clarity and 13 through 21 including the arms 6 and 8. In this embodiment the hinge(s) 5 allow the lens holding portions to displace out of the major surface to lie on top of each other. The hinge 5 is a dual pivoting one, with each pivot having an axis of movement 10 substantially in the plane of the lens holding portions 3 and 4 respectively. A locking mechanism (not shown) may also hold the hinge open (as shown in FIGS. 11A and 12A)—the locking mechanism may be a detent or be biased and require release before folding can occur. The hinge in the embodiment shown resides in a slot 16 in each portion 3 and 4. Other locations for the hinge will now be apparent to a person skilled in the art. The actuation of the hinge 5 is shown in FIGS. 11B and 12B. The closed position is shown in FIGS. 11C and 12C. From here the glasses frame 1 can be attached as earlier described by curling of the arms.
FIGS. 13 through 21 show a minor variation of the glasses frame 1 to that shown in FIG. 11—in this variation the hinge portion 17 is substantially hidden. The hinge portion 17 is shown in FIGS. 14, 16, and 17B when the glasses 1 are partially folded. The hinge axes 18A on the second lens portion 4 and 18B on the first lens portion 3 both lie substantially in the plane of the major surface 11 (for example when unfolded).
When the lens holding portions 3 and 4 are folded as shown in FIGS. 15 and 17C they lie substantially one on top of another. This also provides an element of protection to the lenses 2. The full sequence of unfolded to folded of the lens holding portions 3 and 4 is best seen in FIGS. 17(A) through (C), and in reverse in 18(A) through (C).
The curving, folding or wrapping of the arms 6 and 8 can be seen in FIGS. 19 and 20. The bi-stable material that preferably constitutes them moves to its wrapping position. Shown in FIG. 21 are the glasses 1 folded and wrapped about an elongate object 9, in this case the wrist of a user.
To prepare them for wearing again the glasses 1 are pulled from the wrist and the lens holding portions 3 and 4 unfolded as per FIGS. 18(A) through (C), and the arms 6 and 8 are then pulled straight and they then retain their straightened position. Alternatively the arms 6 and 8 may be straightened first and then the portions 3 and 4 unfolded.
The elongate object 9 the glasses frame 1 can be attached to may be a body part, such as a wrist as shown in FIGS. 5 and 21, or may be an arm, leg or similar. The elongate object 9 may also be a strap, handle or similar, such as for example the strap or handle of a bag. Alternatively the elongate object 9 may be a hook, pipe or other similar object, anything really that is convenient which the user may secure the glasses 1 to when not in use.
There may also be a cover 12 present to cover the lenses 2 when not in use, for example when folded. The cover may be attached to the glasses frame, or may be separate.
In a less preferred form the hinge 5 may have an axis of movement 10 that is in the major surface, thus allowing relative movement again by rotation out of the major surface, such as shown in FIG. 7.
The foregoing description of the invention includes preferred forms thereof. Modifications may be made thereto without departing from the scope of the invention.
