Description

TITLE: FOLDABLE EYEWEAR FRAME THAT CAN BE TAKEN INTO A STORAGE CONFIGURATION IN WHICH THE TEMPLES PROTECT THE LENS HOLDER PORTIONS

The present invention relates to a foldable eyeglass frame capable of being brought into a storage configuration in which the temples protect the lens holder portions.

Glasses are easily damaged when not worn.

The glasses are then often scratched.

It is therefore necessary to store your glasses in a protective case when they are not worn.

However, it is not always easy to take a case with you, which is otherwise bulky.

Document WO 2018/104593 A1 describes an eyeglass frame that can be transformed into a bracelet.

The lenses are placed in the thickness of the bracelet and thus protected from the risk of scratches.

The aim of the present invention is to propose a new device which makes it possible to avoid the risk of scratches when glasses are not worn.

The present invention relates to a foldable spectacle frame of the type comprising a face comprising two lens-holder portions, hollowed out capable of receiving lenses or comprising lenses, a nose bridge which connects said lens-holder portions and two branches, each mounted on one end of said face.

Characteristically, according to the invention, said frame is able to be brought reversibly from a storage configuration, in which said glass holder portions are superimposed and said branches are parallel and arranged on either side of said portions glass holder, to a configuration of use in which said glass holder portions are aligned on either side of said nose bridge, thus defining said face of said frame and said branches are perpendicular to said face.

According to one embodiment, the frame is, in addition, capable of being brought into an intermediate configuration between said storage configuration and said use configuration; in said intermediate configuration, said glass holder portions are aligned and form said face and said branches extend parallel to said face, on either side of the latter.

In said intermediate configuration, said branches can be spaced apart from said glass-holder portions depending on the thickness of said glass-holder portions.

Although this is not limiting to the invention, said glass holder portions can be pivotally mounted on said nose bridge around axes of rotation parallel to the height of said face.

According to a particular embodiment of the frame of the invention, each of said branches is mounted on one of said glass holder portions via at least one upper and/or lower link, a first end of which is pivotally mounted on the thickness of the upper and/or lower edge of one of said glass holder portions, around an axis parallel to the height of said glass holder portion and the second end of which is pivotally mounted on the thickness of the upper edge and/ or lower of said branch around an axis parallel to the height of said branch.

Advantageously, said link and preferably all the links have a curved portion arranged so that in said configuration of use, said link conforms to the surface of the thickness of the upper and/or lower edge of said frame.

Advantageously, whatever the embodiment, the frame includes deactivatable blocking means for each of said branches in said configuration of use of said frame.

These blocking means can be deactivated to release the branch and allow its movement.

According to a particular embodiment of the deactivatable blocking means, they comprise a cam mounted to rotate on each of said branches around an axis perpendicular to the thickness of said branch, means forming a spring which maintain the free end of said cam in a position away from said branch, according to the height of said branch and a blocking element of said link which allows, in the position of use, to block the upper and/or lower link on the upper and/or lower surface of the thickness of said branch.

Advantageously, said blocking element is arranged on said cam, it comprises a surface forming a stop, arranged facing said link in said configuration of use and a guide surface, opposite said surface forming a stop and said guide surface is shaped to cooperate with said link during the transition from said storage configuration to said use configuration so as to press the free end of said cam against said branch to allow passage of said link over said blocking element.

The spring means are not limited according to the invention.

They may include an elastic blade provided in said branch and extending parallel to the length of said branch.

This blade can be, for example, formed by a longitudinal recess made in the branch.

Advantageously, whatever the embodiment of the invention, said branch comprises means forming a wedge which cooperate with said cam so as to limit the spacing of the free end of the cam relative to said branch.

According to an embodiment combinable with each of the aforementioned embodiments, in said configuration of use, the vertical edge of each of said branches abuts against the vertical edge of one of said glass holder portions.

In this way, the branch is locked in a position which allows the frame to be worn.

Advantageously, the branch is also blocked in a position perpendicular to the face thanks to the blocking element, which can be the aforementioned cam.

For greater clarity, identical or similar elements are identified by identical or similar reference signs throughout the figures.

In reference to the , the particular embodiment of the invention comprises a face 1 and two branches 3.

Face 1 has two glass holder portions 11 which surround a glass 2, a nose bridge 12 which connects the two glass holder portions 11.

On the , the vertical edge 33 of the protective portion 31 of the branch 3 abuts against the vertical edge 13 of the glass holder portion 11.

The branch 3 comprises a portion of lower height which extends behind the protective portion and which is able to come to rest on the ears of the user.

Still with reference to the , the mount comprises an upper link 51, a lower link 52 and a cam 7.

Each link 51, 52 comprises a first end 510, 520 mounted respectively on the upper and/or lower surface of the thickness of the glass holder portion 11.

This first end 510, 520 is pivotally mounted around an axis X parallel to the height of face 1 and passing next to glass 2, close to branch 3.

Each link 51, 52 has a second end 512, 522 mounted on the upper and/or lower surface of the thickness of the protective portion 31 of the branch 3.

This second end 512, 522 is pivotally mounted around an axis (not shown) also parallel to the height of face 1.

Cam 7 is used to lock the links in position when the mount is unfolded in use configuration, as shown in the figure. .

Cam 7 has an end 70 pivotally mounted around an axis Y, perpendicular to the thickness of branch 3.

The other end of cam 7, which is oriented towards face 1, is free to have a movement in the vertical direction, that is to say according to the height of branch 3.

The cam 7 is mounted on the upper surface of the protective portion 31 of the branch 3; it will be more fully described with reference to the .

In reference to the , the cam 7 has on its side located between the branches 3, a blocking and guiding ramp 71.

The ramp 71 has a guide surface 72 which is inclined towards the space located between the branches 3, when the mount is in use configuration.

The ramp 71 has a substantially vertical surface 73 opposite the inclined surface 72.

This vertical surface 73 abuts against the upper link 51, thus cooperating with the vertical edges 33 and 13 to lock the upper link 71 in position and block the branch 3 in a position where it forms an angle of 90° from face 1 .

When the frame is in storage configuration, the locking and guiding ramp 71 is located on the external face of the branches 3, the lens holder portions 11 being arranged in the space located between the branches 3.

On the , we see that the upper link 51 matches the shape of the frame; it therefore includes a curved portion which is superimposed on the thickness of the frame, at the junction of face 1 and branch 3.

In reference to the , branch 3 comprises an elastic blade 35 formed by a recess managed in the thickness of the protective portion 31 of branch 3.

This blade 35 extends longitudinally to branch 3.

The free end 351 of the blade is oriented towards face 1, when the mount is in the usage configuration.

A through opening 37 comprising a shoulder 371 is provided under the upper link 51.

The free end of cam 7 includes a portion housed in opening 37 and which abuts against shoulder 371.

The blade 35 in fact pushes the cam 7; the latter rotates around the Y axis and its free end rises and then abuts against the shoulder 371.

In this position, the upper surface of the cam 7 is substantially aligned with the upper surface of the thickness of the branch 3.

Only the blocking and guiding ramp 71 protrudes above the branch 3 and the upper link 51, thus blocking the branch 3 at 90° from face 1.

The diagram of the shows the mount in intermediate configuration.

The glass holder portions 11 are aligned and form face 1 as in the usage configuration.

The branches 3 are arranged in a plane parallel to the face 1, slightly above the latter due to the curved portion of the links 51, 52

There represents the frame of the invention in storage configuration.

Cams 7 are not shown for the sake of simplification.

In this configuration, the glass holder portions 11 are pivoted towards the same side of the nose bridge 12.

The two glass holder portions 11 are therefore parallel to each other and perpendicular to the nose bridge 12.

Branches 3 are returned relative to the usage configuration.

Thus the portion of reduced height which is arranged behind the face 1 in use configuration is, in the storage position, arranged near the face of the nose bridge 12.

The vertical edges 33 and 13 are both distant from the nose bridge 12.

The branches 3 are parallel to the glass holder portions 11, which are sandwiched between the branches 3.

The folding kinematics of the frame of the invention will now be described with reference to at 6.

The mount is in storage configuration as shown in the .

The user grasps the free end of the branches 3, at the level of the vertical edges 33 and aligns the glass holder portions 11 on either side of the nose bridge 12.

The branches 3 are then aligned above the face 1 formed by the glass-holder portions 11.

He then pulls on the branches 3 so as to separate them from each other and bring them into the intermediate configuration shown on the .

In doing so, the upper link 51 slides on the inclined surface 71 of the ramp 7.

The upper link 51 therefore presses on the cam 7, which crushes on the branch 3 to allow the upper link 51 to pass above the cam 7.

The user then folds branches 3 so that they form a 90° angle with side 1.

The upper link 51 abuts against the vertical surface of the ramp 71 and the vertical sections 13 and 33 abut against each other, thus blocking the branch at 90° from face 1 thanks to the links which hold the assembly and prevent the mobility of the branches around the axes of rotation of the links.

The mount folding movements are the same as those shown above but in reverse order.

To unlock the passage from the intermediate configuration to the storage configuration, the user presses the cam 7 so as to lower the latter and allow the passage of the link 51 over the blocking and guiding ramp 71.

He can then bring the branches into the storage position.

Naturally, the invention is described in the above by way of example.

It is understood that those skilled in the art are able to carry out different variants of the invention without departing from the scope of the invention.
