Description
"FRAME FOR SPECTACLES"
FIELD OF THE INVENTION
The present invention concerns a frame for spectacles having two arm- pieces assembled removably on a lens-bearing body, or directly on the lenses. In particular, the frame according to the present invention provides a removable coupling of the arm-pieces to the lens-bearing body without using auxiliary hardware elements and hence the assembly and dis-assembly thereof do not require specific tools. BACKGROUND OF THE INVENTION
Frames for spectacles are known, substantially consisting of two arm-pieces hinged to a lens-bearing body or directly to the lenses.
Frames are also known where the arm-pieces can be detached from the lens-bearing body, or from the lenses, so that the user can replace them individually if they break or malfunction, or simply to modify the aesthetic appearance of the spectacles as desired.
This type of known frames normally provide to assemble the arm-pieces to the lens-bearing body or the lenses by means of screws, normally very small with lengths in the range of some millimeters. Therefore, in order to replace the arm-pieces, the user has to operate with specific and very small tools, with difficulties in manipulation and with the risk of stripping the thread or losing the screws, thus compromising the assembly of the new arm-piece.
These operating difficulties are even more evident when the operations to replace the arm-pieces are performed by elderly persons or persons with visual impairment.
Purpose of the present invention is to achieve a frame for spectacles with arm-pieces that can be detached and re-assembled by any user in a simple and rapid manner, and without the aid of specific tools. The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
SUMMARY OF THE INVENTION
The present invention is set forth and characterized in the main claim, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.
In accordance with the above purpose, a frame for spectacles according to the present invention comprises two ami-pieces assembled removably on a lens-bearing body, or directly on the lenses, of the spectacles.
According to a characteristic feature of the present invention, each arm- piece comprises, at one end, elastic attachment means, while the lens-bearing body, or the lenses, comprises an anchoring means that directly cooperates with the elastic means to determine the releasable snap-in assembly of the arm-pieces on the lens-bearing body, or on the lenses.
With the present invention, thanks to the snap-in assembly of the arm- pieces, small-size auxiliary hardware elements or specific tools that are difficult to use, are therefore not necessary. In this way, any user whatsoever can dis-assemble and re-assemble the arm- pieces autonomously, in a simple and rapid manner and without running the risk of compromising the assembly of the arm-pieces on the lens-bearing body or on the lenses.
BRIEF DESCRIPTION OF THE DRAWINGS These and other characteristics of the present invention will become apparent from the following description of a preferential form of embodiment, given as a non-restrictive example with reference to the attached drawings wherein:
- fig. 1 is a three-dimensional view of a pair of spectacles having a frame according to the present invention;
- fig. 2 is an exploded view of an enlarged detail of fig. 1 ;
- fig. 3 shows a section of the detail in fig. 2, in the assembled condition.
DETAILED DESCRIPTION OF A PREFERENTIAL
FORM OF EMBODIMENT With reference to the attached drawings, a frame 10 according to the present invention for a pair of spectacles 11, comprises a body 12 that supports two lenses 13, prescription lenses or sun lenses, and two arm-pieces 15 assembled at the sides of the body 12, folding with respect to the latter by
means of respective hinges 17.
In particular, each arm-piece 15 comprises, in correspondence with one front end 15a, two elastic elements 20 and 21, terminally conformed as a hook, bent in an L shape and substantially parallel with each other, so as to define an elastic gripper.
In this case, each elastic element 20, 21 is formed by a wire thread bent back on itself so as to define at least two respective rectilinear segments 20a, 20b and 21a, 21b, substantially parallel with each other, connected by a hook- shaped end. The body 12 comprises at the sides, in correspondence with each of the assembly zones of the arm-pieces 15, a first sunken anchoring seating 22 made on a front surface 12a, and a second sunken anchoring seating 23 made on a rear surface 12b.
In particular, each sunken anchoring seating 22, 23 is substantially U- shaped, so as to house inside it the rectilinear segments 20a, 20b and 21a, 21 b of the corresponding elastic element 20, 21 , preventing the latter from accidentally slipping out laterally.
To this purpose, the distance between the elastic elements 20 and 21 when they are inactive is slightly less than the thickness of the body 12 in the coupling zone of the arm-pieces 15, so that the insertion of the elements 20, 21 into the sunken seatings 22, 23 occurs with a forced spreading apart of the elements 20, 21.
The elastic return then determines the stable positioning thereof inside the relative sunken seatings 22, 23. If the user decides to replace one or both the arm-pieces 15, it is then sufficient to reciprocally spread apart the two elastic elements 20 and 21 , so as to free them from the respective anchoring seatings 22 and 23. The action of spreading apart the two elastic elements 20 and 21 can be performed easily by means of a common tool, such as for example a screwdriver, but also by means of any other oblong object that can be inserted between the two elastic elements 20 and 21, in order to apply leverage that allows to overcome the elastic action effected by the two elastic elements 20 and 21.
It is clear, however, that modifications and/or additions of parts may be
made to the frame 10 as described heretofore, without departing from the field and scope of the present invention.
For example, it comes within the field of the present invention to provide that the two housing seatings 22 and 23 can be made directly on the front and rear surfaces of the lenses 13, so as to assemble the arm-pieces 15 directly on the lenses 13.
It also comes within the field of the present invention to provide that the elastic elements 20 and 21 can be of the type inserted under pressure into the seatings 22 and 23, or are provided with knurlings, notches or other workings that improve the coupling thereof with the seatings 22 and 23.
It is also provided by the invention that the sunken seatings are made at the end of the arm-pieces, and that the snap-in attachment elements are provided on the lens-bearing body.
