ABSTRACT:
TECHNICAL FIELD
This invention relates to a spectacle frame.
BACKGROUND ART
It is understood that many spectacles, whether optical glasses worn on a daily basis or sun glasses, are already known. Now, when someone wears spectacles, it sometimes happens that he has to temporarily take them off, while he nevertheless wishes to keep them within hand reach.
At that occasion, one will often have a tendency to put the spectacles in the bottom of a pocket. Besides the fact that it is possible to find in the latter objects that are likely to damage the lenses of the spectacles, it sometimes proves uneasy to withdraw them. Such an operation may furthermore prove particularly difficult, e.g. when practising sports that require wearing gloves, such as ski or cycling. In addition, while doing so, it often occurs that some movements, even the mere fact of bowing down, cause these spectacles to accidentally and involuntarily slide out off the pocket. The spectacles then fall onto the floor, which often results in damaging them or, when the fall is not noticed immediately, in merely losing them.
It is obvious that, in all the preceding cases, it is assumed that the person wearing the spectacles has also put on a garment provided with an easily accessible pocket, which is not always the case, especially in the case of sportswear.
Another solution then consists in providing the frame with a string each end of which is connected to one side of the spectacles. Thus, when they are no longer needed, it is possible to take off one's spectacles, which remain hanging at one's neck, being retained by the string. Though this solution is widely spread, it is however no ideal one, since it is possible for the string to pass over one's head and for the spectacles to thus drop onto the floor. In addition, a connection between the string and a side of the spectacles is in most cases brought about by means of a running-type knot the grip of which has, in the course of time, a tendency to loosen, with the consequences one can imagine.
From the Japanese document JP-07 244260 it is known a spectacle frame capable of being fixed to a metallic support. Such a frame includes, on the front face, fixing means of a magnetic kind that are in the shape of one or several protrusions, either inserted against the frame or moulded during the manufacturing of the latter. These protrusions are provided with an end of a magnetic kind capable of entering into contact with a metallic support, in order to ensure the fixing of the spectacle frame on the latter. One should note that these magnetic ends are arranged in a plane substantially arranged at the front side of the curvature of the lenses, so that the latter are protected only when the spectacle frame is fixed on a metallic support providing a strictly planar surface, which is seldom the case.
SUMMARY OF THE INVENTION
Therefore, the present invention overcomes the aforementioned drawbacks, this by means of a spectacle frame capable of being fixed, in particularly temporarily, on a receiving support that may be of a largely varying nature, such as a garment, a dashboard of a vehicle, a frame of a bicycle, etc. This device is of a relatively easy design and particularly efficient in use.
To this end, the invention relates to a spectacle frame characterized in that it is provided with means of a magnetic kind for the fixing on a support.
According to a first embodiment, the fixing means of a magnetic kind includes at least one magnet associated to the spectacle frame. This advantageously allows to fix the spectacles on any kind of ferrous support.
The invention also relates to bases for receiving such a spectacle frame, which bases are aimed at being inserted against any support, such as a garment, the frame of a bicycle, etc., such a base therefore including adequate means for the fastening to this support.
Finally, the magnetic fixing means can be in the shape of a combination, on the one hand, of a spectacle frame at least one of the components of which is made of a magnetic or non-magnetic ferrous metallic material or includes a part made of such a material and, on the other hand, of a magnetic base including adequate means for the fastening to a support.
The invention also relates, independently, to such magnetic bases for receiving spectacle frames.
The advantages resulting from the present invention reside in that it is possible to take off one's spectacles, in order to quickly, efficiently and strongly fix them temporarily on a support of a ferrous kind, such as a frame of a bicycle, or on a base made integral, through adequate means, with any support, such as a dashboard of a vehicle, a bicycle, a garment or the like.
One should note that the fixing means of a magnetic kind are so designed as to allow a particularly efficient connection between any support and the spectacle frame, so that the risks of sliding and falling on the ground, with the consequences this involves, are particularly reduced.
Further aims and advantages of the present invention will become clear during the following description that relates to an embodiment that is given only by way of an indicative and non-limiting example.
