"BINOCLE"
The present invention relates to a one-piece molded binocle comprising a substantially planar structure having a first edge provided with a first lens and a second edge provided with a second lens, said structure having a plane passing through said first and second borders and said first and second lenses, said first and second borders being extended one and the other by a junction which connects them to one another, said junction being arranged to be in contact with a holding element intended to be placed on the nose of a user.
Such a binocle is known from the state of the art. It has no branches and is intended to be placed on the nose of a user. In this way, the binocle is supported only on the nose.
It is known that the use of such a binocle is not practical in use since it is not maintained steadily on the nose of the user. In addition, when the user moves with the binocle on the nose, the binocle can easily switch or be moved when the user is moving. Consequently, such a binocle is not practical in use because the user is forced to use it while being as little as possible in motion, which greatly limits the use of such a binocle.
In an attempt to improve the maintenance of the binocle on the nose of the user, it has been proposed to provide a binocle said "pinch nose" which is actually uncomfortable for the user who has to endure a relatively intense pinch. The comfort quality of such a binocle is greatly limited. Other binocles have been developed to avoid the aforementioned problems. The use of a binocle has quickly evolved to the addition of a branch on one side of the structure so that the user can maintain the branch of the binocle and thus keep the binocle on his nose.
Unfortunately, the maneuverability of such a binocle is limited because, with such a configuration, the user is forced to maintain the binocle when he uses it to read. It is obvious that such a binocle is neither comfortable nor practical to use.
There is also a new generation binocle to which is added a holding element. Such a binocle is disclosed in the document KR 2012 000 2025 which describes that the holding member is intended to be placed on the nose of a user. When the binocle is placed on the nose of the user, it has a dorsal face facing the user and a front face facing the surrounding environment. The disclosed holding member is attached to the dorsal surface at the junction of said first and second borders. The holding element comprises two circular elements which are not included in the plane of the binocular structure. The two circular elements have a first position called "parallel" and a second position called "opening". In the first position, the two circular elements are parallel to each other and in the second position, the two circular elements are spaced relative to each other, creating a free space. The user wishing to fix the binocle on his nose must separate the two circular elements in second position so that the nose has access to the created space. Then, the passage from the second position to the first position makes it possible to fix the binocle, by means of the holding element, on the nose.
It is apparent from the aforementioned document that the binocle with the holding element is not comfortable when it is placed on the nose of the user and this because of the presence of the two circular elements that protrude outward of the eyeglasses. Indeed, the user must constantly discard and reconcile the two circular elements to hope that the binocular fits on his nose. Once the binocle resting on the nose, it is not excluded that the two circular elements depart again and do not pinch the nose of the user. The maintenance and stability of such a binocle on the nose of a user can not be guaranteed. Binocular stability is therefore not ensured when the user leans forward or when he is moving.
However, as described above, it is preferable to be able to provide a binocle that is comfortable and stable so that the binocle is maintained on the nose, even when a user is moving. Wearing such a binocle is therefore not practical and reliable in use.
In addition, the reciprocating movement of the two circular elements during use in the long term uses the two circular elements of the holding element disclosed in the document KR 2012 000 2025. The reliability of such a binocle therefore can not be ensured over a long period of time.
In view of the foregoing, the use of a binocular seems at first sight difficult in view of the many limitations of binocles known in the state of the art and for which the aforementioned problems could not be countered until now. At present and in view of the foregoing, it is clear that there is a real need to provide a binocle whose reliability can be ensured over a longer period of time compared to known binocles, which has an ease manipulation without harming the stability of the binocle on the nose of a user, even when it is in motion. This will make it pleasant and practical to wear a binocle. The invention aims to overcome the drawbacks of the state of the art by providing a binocle that is easily manageable, comfortable to use, which is reliable compared to the binoculars of the state of the art and whose maintenance on the nose of a user can be guaranteed for use even when the user is moving.
To solve this problem, it is provided according to the invention, a binocle as indicated at the beginning characterized in that said junction is curved and has a first and a second inflection points.
Thus, the presence of the first and second inflection points at the junction makes it possible to provide a binocle with a particularly flexible curved junction since at each point of inflection there is a change in concavity. The flexibility of the junction makes it possible to adjust the nasal gap situated between the first and second lenses, which has the advantage that the binocular according to the invention can be adapted to any type of nose.
It is thus possible to bring the first and second lenses relative to one another and thus the two points of inflection relative to each other so as to substantially reduce the nasal gap.
In addition, it has been found that the junction having a first and a second inflection point also makes it possible to move the first and second lenses relative to one another so as to adapt again the difference between the first and second lenses.
The binocle according to the invention also has the advantage of being more robust compared to the binoculars of the state of the art because the flexibility of the junction allows it to adopt several orientation thus reducing the risk of breakage.
The binocle according to the invention is thus easily manipulated since it is easy to separate or bring the first and second lenses together without risking breaking the binocle.
In addition, the binocle according to the invention is arranged to be in contact with a holding element which is intended to be placed on the nose of the user.
It has surprisingly been found that the presence of the first and second inflection points allow the holding member to take hold of the binocular structure reversibly. Thus, once attached to said binocle, the holding element is completely integrated in the structure thereof.
In the context of the present invention, it has been found that the integration of the holding element having a predefined planar geometry in the binocular structure allows it to register in the plane of the binocular structure. Since the plane of the structure also passes through said first and second borders and said first and second lenses, the addition of the holding element on the binocle makes it possible to truly confuse the predefined plane geometry of the holding element. with the structure of the binocle. The plane geometry of the binocle is thus defined in the plane of the binocular structure.
When the binocle comprises the holding member, the holding member does not affect or very little the position of the binocular center of gravity. This has the advantage that during the installation of the binocle comprising the holding member, there is no counterweight that could reduce the maintenance of the binocular placed on the nose of the user.
Thus, the binocle according to the invention makes it possible to offer the user comfort in use, reliability and easy maneuverability.
Advantageously, said junction has on one side of the first point of inflection a first junction part and on the other side of the first point of inflection a second junction part and a side of the second point of inflection, said second junction portion and the other side of the second inflection point a third joining portion, said first and third portions of said juncture having an upward concavity, when the binocular is in the ready-to-wear position.
The junction may have three successive curved parts where the first and third parts have a concavity upwards which allows to further increase the flexibility of the binocular junction.
This has the advantage that the user can adjust the nasal gap by placing his fingers on the first and third curved portions which have an upward concavity, which allows to define a hollow portion for the fingers of the user.
In a particularly advantageous manner, the first part of the junction is connected to the first edge of the binocle by means of one of its ends and the third part of the junction is connected to the second edge of the binocle by means of one of its ends. .
In a particular embodiment, said first rim provided with the first lens partially surrounds said first lens and said second rim provided with the second lens partially surrounds said second lens, said first and second rims having a thickness at least greater than that of said first lens. and second lenses.
This preferred mode has the advantage of leaving part of the first and second lenses free to optionally add other binocular structure elements.
In a particularly advantageous embodiment of the device according to the invention, the first and third parts of said junction each have a radius of curvature ranging from 2 to 6 mm, preferably from 3 to 5 mm, more preferably equal to 3 mm.
In addition, a junction with at least one concave part downwards is particularly favorable to the flexibility of the binocular junction, which is preferred in the context of the present invention.
Preferably, said second portion of said junction has a concavity downwards which provides a contact surface for a holding member.
In addition, in a particular embodiment, said second portion of said junction has a radius of curvature ranging from 1 to 3 cm, preferably from 1.5 to 2.5 cm, more preferably from 1.5 to 2 cm, this makes it possible to adjust the curvature of the first and third parts of the junction.
Advantageously, the binocular according to the invention has a first ready-to-wear position in which the binocular is arranged to be placed on the nose of a user and in which the junction is in the rest position where the first and second inflection points are spaced from each other and a second position in which said first edge at least partially covers said second edge and wherein the junction is in the tension position where the first and second inflection points are brought closer together; the other. The advantage of such an embodiment makes it possible to reduce the size of the binocle and store it in a pocket when it adopts the second position. In addition, the nasal gap can still be adapted to wish by directing the binocle from the first position to the second position.
Preferably, said first and second lenses or the first and second borders are each provided with connecting means arranged to engage said holding member to said binocle, which allows to fix a holding member to the binocular structure.
Preferably, said connecting means are selected from the group consisting of fins, protuberances, preferably rigid protuberances, as protuberances in the form of buttons or fungi and their combinations.
Even more preferentially, said binocular according to the invention is made of a material chosen from the group consisting of elastomers, preferably polycarbonate, polyurethane, glass or their combinations.

The invention also relates to a holding element which is intended to be used with the binocular structure according to the present invention, said holding element having a curved shape and comprising a first and a second inflection point.
Advantageously, the holding element according to the invention has on one side of the first inflection point a first portion and on the other side of the first inflection point a second portion and a side of the second point. inflating said second portion, and on the other side of the second inflection point a third portion, said first and third portions having an upward concavity and said second portion having a concavity downwardly.
Thus, the shape of the holding element according to the invention is adapted to the shape of the junction binocle so that its attachment to the binocle is made easy.
Preferably, the holding element according to the invention comprises five curved parts where the first, second and third parts are arranged to be respectively in contact with the first, second and third parts of the junction of the binocle and where the fourth and fifth parts are arranged to be fixed to said binocle by means of said connecting means.
This has the advantage that several parts of the holding element are capable of being fixed to the binocular according to the invention.
Preferably, the holding member is made of material selected from the group consisting of elastomers, preferably polycarbonate, polyurethane, silicone, more preferably thermoplastic elastomers or combinations thereof. Other embodiments of the holding member according to the invention are indicated in the appended claims.

This has the advantage of being able to accommodate said binocle according to the invention when it is in the second position, that is to say when the two points of inflection approach one another. Thus, once housed in the case, the junction binocle according to the invention is slightly under tension which allows to sufficiently maintain the binocular in the case.
Advantageously, the case according to the present invention is provided with the binocular according to the invention, said binocle possibly being provided with the holding element according to the invention and in which the length of said case is less than or equal to that of the binocle in first position such that when the binocle in first position adopts the second position, it can be inserted into said case and thus be sufficiently maintained.

Figure 8 shows a part of the case according to the invention.
In the figures, identical or similar elements bear the same references.
In the context of the present invention, the term "upward concavity portion" should be understood to mean that the relevant portion has a downward-facing bottom and an upward-facing opening.
In the context of the present invention, the term "part having a concavity downwards" should be understood to mean that the part concerned has a bottom oriented upwards and an opening facing downwards.
In the context of the present invention, the term "nasal gap" means the distance between the first lens and the second lens at the junction.
The structure of the binocle 1, illustrated in Figure 1, comprises a first border 2A and a second border 2B which are extended by a junction 4 which connects them to one another. The junction 4 is in contact with a holding member 6 which is intended to be placed on the nose of a user.
The first and second borders 2A, 2B binocle 1 are logically provided with lenses 3A, 3B. The first edge 2A partially surrounds said first lens 3A and the second edge 2B partially surrounds said second lens 3B.
The portions of the first and second edges 2A, 2B which are in contact with the holding member 6 have a thickness at least greater than that of said first and second lenses 3A, 3B.
As shown in FIG. 1, the junction 4 of the binocular 1 is curved and has two points of inflection 8, 9 which give the binocular 1 an advantageous flexibility. This allows the binocular 1 according to the invention to adopt several orientations.
More precisely, the junction 4 has on one side of the first inflection point 8 a first junction portion 4A connected to the first edge 2A and on the other side of the first inflection point 8 is a second junction portion 4B which extends said first portion 4A of the junction 4 binocle 1.
In addition, the junction 4 also comprises on one side of the second inflection point 9, the aforementioned second junction portion 4B and on the other side of the second inflection point 9 a third junction portion 4C which is connected to the second 4C border.
Said first and third parts 4A, 4C of said junction 4 have an upward concavity, when the binocular 1 is in the ready-to-wear position, which corresponds to a position where the two points of inflection are distant one of the other, as shown in Figure 1.
Said second portion 4B of said junction 4 has a concavity downwards.
Thus, the passage between the first part 4A of junction 4 to the second part 4B of junction 4 defines the first point of inflection 8 where the change of concavity takes place and the passage of the second part 4B of junction 4 to the third joining part 4C defines the second point of inflection 9.
According to the embodiment illustrated in FIG. 1, the binocle is in a first position called "ready-to-wear position", which corresponds to a rest position of the junction 4 where the first and second inflection points 8, 9 are distant from each other. In this position, the user only has to place the binocle on his nose.
Advantageously, the flexibility of the binocular 1 according to the invention allows the user to move away if he still wishes the first and second points of inflection 8, 9 relative to each other. In this way, it can spread the first and second borders 2A, 2B to facilitate its placement on the nose.
As can be seen in Figure 1, the first and third parts 4A, 4C of the junction 4 can allow the user to place these fingers in the hollow thus formed to hold the binocle 1 easily.
In a still advantageous manner, the first and third parts 4A, 4C of said junction 4 have a radius of curvature ranging from 2 to 6 mm, preferably from 3 to 5 mm, more preferably equal to 3 mm.
Preferably, said second portion 4B of said junction 4 has a radius of curvature ranging from 1 to 3 cm, preferably from 1.5 to 2.5 cm, more preferably from 1.5 to 2 cm.
The binocular structure 1 can be made of flexible or rigid material. Preferably, the structure may be made of elastomers, for example polycarbonate, polyurethane. It is also possible to provide the binocular structure 1 of glass or any other material to provide a binocular structure 1.
The binocular structure 1 may be made using any known method for manufacturing such a structure, for example by a single-injection technique that directly provides the binocular structure 1 or by an injection technique that allows to manufacture the binocular structure 1 without the lenses 3A, 3B, the latter can be added in a second time. It is then possible to combine several materials together to provide the structure of the binocle 1.
The structure of the binocle is thus molded in one piece which greatly facilitates its manufacturing process.
An advantageous embodiment consists in producing a polycarbonate structure to which glasses are attached. It is also possible to provide a binocle comprising a completely silicone holding element. The holding element 6, illustrated in FIG. 1, has a predefined planar geometry such that it can be fixed to the structure of the binocular 1 according to the invention so as to provide a stable, reliable and comfortable binocle 1 to the use.
In this preferred embodiment, the holding element takes hold at the junction 4 and the first and second borders 2A, 2B of the binocular 1.
As shown in FIG. 1, the holding element 6 has a curved shape and comprises a first and a second inflection point 6F, 6G. At each point of inflection 6F, 6G corresponds to a concavity change which thus has the same advantage as the binocle, in this case an advantageous flexibility which enables it to withstand any possible deformation. The holding element 6 according to this embodiment comprises 5 successive curved portions: a first portion 6A, a second portion 6B, a third portion 6C, a fourth portion 6D and a fifth portion 6E.
The first portion 6A and the third portion 6C of the holding member have an upward concavity and the second portion 6B of the holding member 6 has a concavity downwardly.
The first, second and third parts 6A, 6B, 6C respectively cooperate with the first, second and third parts 4A, 4B, 4C of the junction 4 of the binocular 1 where they can take hold.
The fourth and fifth parts 6D, 6E of the holding element 6 are fixed respectively to the first and second borders 2A, 2B of the binocular 1. The holding element 6 is made of a material selected from the group consisting of elastomers, preferably polycarbonate, polyurethane, silicone, more preferably thermoplastic elastomers or combinations thereof.
Thus the holding element 6 may have the same material as the binocular structure 1. However, the holding element 6 is advantageously manufactured in a softer material than the binocular structure 1 to improve the comfort of the binocular 1 carried by means of the holding member 6, which is intended to be placed on the nose of the user.
According to the present invention, it is particularly advantageous to be able to provide a holding element 6 formed in one piece so as to facilitate its implementation, its integration into the binocular structure 1 and its replacement.
Preferably, the holding element 6 can be fixed at the junction 4, on the first and second lenses 3A, 3B, or on the junction 4 and the first and second lenses 3A, 3B.
Advantageously, the junction 4 according to the invention has a width of between 1 and 8 mm and a thickness of between 0.05 and 1.5 mm.
Figure 2 is a perspective illustration of a binocular 1 according to the present invention and a holding member 6 according to the invention.
The structure of the binocle comprises all the elements presented for the binocle illustrated in FIG. 1 except that connection means 7 are present on the first and second lenses 3A, 3B and that the first and second borders 2A, 2B consequently surround the first and second lenses 3A, 3B.
Said first edge 2A of the binocular 1 provided with the first lens 3A surrounds the latter partially and said second edge 2B of the binocular 1 provided with the second lens 3B partially surrounds said second lens 3B. In this way, a portion of the edge of the first lens 3A faces a portion of the edge of the second lens 3B, at the junction 4 of the binocular.
This allows to leave a free space for two connecting means 7 arranged on the first and second lenses 3A, 3B.
In addition, said first and second edges 2A, 2B have a thickness at least greater than that of said first and second lenses 3A, 3B.
The connecting means 7 are in the form of buttons having a rounded head and a base connecting the head to the corresponding lens. The holding element 6 has the same structure as that described for the holding element shown in FIG.
In this embodiment, it can be seen that the holding member 6 has a plurality of orifices designed to be engaged at the buttons.
When the holding element 6 is positioned on the junction 4 of the binocular 1, the orifices are positioned opposite the buttons which are then threaded into the orifices, forcing the passage of the head so that the bases are housed in the orifices. and that the larger section heads ensure the positioning of the holding element 6 binocle 1. In this way, the shape of the buttons can slightly move the holding element 6 from the front to the back, and conversely, relative to the binocle 1, which further improves the positioning of the binocle on the nose of a user.
It emerges from FIG. 2 that a plane π passes through the structure of the binocle 1 and also the first and second borders 2A, 2B and the first and second lenses 3A, 3B. This figure illustrates the fact that the holding element 6 fits in the plane π of the binocular structure 1 so that it is ideally integrated in the binocular structure 1. This makes it possible to provide a binocular 1 which comprises a holding element 6 whose weight is symmetrically distributed in its structure. Thus, the position of the center of gravity of the binocular 1 is not affected by the presence of the holding element 6. The illustration of FIG. 2 makes it possible to highlight a way in which the product can be presented once it has been put in place. on the market for its sale. The components of the binocle 1, in this case the structure of the binocular 1 and the holding element 6, can be provided separately. In this way, the user can then simply fix the holding element 6 at the junction 4 where it can take hold in the binocular structure 6 to thereby form a binocular 1 ready to be worn.
It is understood that the connecting means may have any other form such as that selected from the group consisting of fins, protuberances as having the shape of mushrooms or combinations thereof.
Advantageously, the connecting means 7 may be in the form of buttons, preferably two in number, which have a rounded head and a base of section smaller than that of the rounded head.
When the connecting means 7 consist of fins and buttons, the displacement of the holding member 7 is even more limited from front to rear relative to the binocle 1. In addition, the presence of fin allows to guide the holding member 6 when attached to the structure of the binocular 1 and the buttons to keep it in position.
The binocle 1 thus developed is easily manageable, stable on the nose of the user, reliable and comfortable to use.
It is understood that the holding element (6) can be fixed to the binocular structure 1 in a reversible manner which allows to replace it easily. This replacement is easily and quickly achievable since it suffices to dislodge the holding element 6 of the connecting means 7. Thus, when the user wishes to change the binocular style, he can simply replace the holding element 6 with a other. The holding element 6 can be in several colors (blue, pink, yellow, green, red, black, etc.) so that the user can have the choice of the color of the holding element 6 Thus, the binocle 1 can have at least two color variations, preferably a series of colors.
Preferably, the holding member 6 can be provided in different sizes, for example three different sizes, to allow the user the choice to select the holding member 6 which is suitable for the size of the user's nose.
Note that in the context of the present invention, the structures of the binocle 1 and the holding element 6 according to the invention advantageously allow to adapt to any type of nose thanks to the flexibility and the maneuverability of the binocular which can so present several orientation.
FIG. 3 illustrates a binocular variant 1 according to the invention which has all the described elements of the binocle 1 illustrated in FIG. 1, except that the connecting means 7 are different.
The illustrated binocle 1 is in a first ready-to-wear position in which the binocular 1 is arranged to be placed on the nose of a user. In this first position of the binocular 1, the junction 1 is in the rest position and the first and second inflection points 8, 9 are distant from each other.
In this embodiment, the connecting means 7 are six in number and are in the form of four fins and two buttons.
The fins 4 facilitate guiding the holding member 6 and limit the movement thereof from front to rear, and vice versa, relative to the binocular.
The buttons are used to engage the holding member 6 and keep it in position.
The structure of the binocular 1 is preferably made of polycarbonate 1 and the holding element 6 of silicone.
Figure 4 illustrates a preferred embodiment of the binocular 1 of Figure 3 when in a second position. As illustrated, the binocular 1 is in a position in which the first edge 2A at least partially covers the second edge 2B and in which the junction 4 is in the tension position where the first and second inflection points 8, 9 are brought closer together. one of the other.
More specifically, in this embodiment, the first border 2A is in a first plane and the second border 2B is in a second plane. The first and second planes being parallel to each other.
The junction 4 of the binocular 4 in tension position is in a third plane which is secant with respect to the first and second planes.
In this embodiment, the binocular 1 according to the invention can be stored in this position, for example in a pocket of a user, which is particularly advantageous.
In addition, when the binocular 1 adopts the second position and the junction 4 is in the tension position, it has been found that the nasal gap between the first and second lenses 3A, 3B is reduced. Thus, the passage from the second position to the first position of the binocle 1 according to the invention makes it possible to adjust the nasal gap at will.
The binocle 1 illustrated may also comprise a holding element 6 according to the invention and have the first and second positions. The holding member 6 may be made of material selected from the group consisting of elastomers, preferably polycarbonate, polyurethane, silicone, more preferably thermoplastic elastomers or combinations thereof.
The material of the holding element 6 has a coefficient of elasticity such that it makes it possible to bring the first and second inflection points 6F, 6G to one another, when the binocular 1 adopts the second position of so that the junction 4 of the binocular 1 is oriented in the position of tension.
In addition and advantageously, the holding element 6 has a coefficient of elasticity such that it contributes to maintaining the binocular 1 in the first position where the junction 4 is in the rest position.
Advantageously, the binocular 1 according to the invention has a first position in which the junction 4 is in the rest position where the first and second inflection points 8, 9 are spaced from each other. The binocle 1 according to the invention also has a second position in which the junction 4 is in the tension position in which the first and second inflection points 8, 9 are brought closer to one another.
Figure 5 illustrates the binocular 1 provided with the holding member 6 shown in Figure 1 and a case 16 according to the invention.
The length of the binocle 1 is defined as the distance between the farthest ends of the binocle in the first position, in the direction of the length of the binocular 1.
Preferably, the binocle has a length of between 8 and 11 cm, preferably 9 cm, more preferably 9.8 cm.
In this embodiment, the case 16 has a length less than or equal to that of the binocular 1.
In this way, the user wishing to store the binocular 1 according to the present invention can maintain the binocular 1 in the first position at the first and third parts 4A, 4C of junction 4 and then slightly close the two points of inflection 8.9 towards each other to reduce the length of the binocular 1 and allow the easy insertion thereof into the case 16 according to the invention. Thus, the binocular 1 then adopts the second position in which the junction 4 is slightly under tension and the first and second inflection points are substantially close to one another.
FIG. 6 illustrates the case 16 of FIG. 5 comprising the binocular of FIG. 5 with the holding element 6.
When the binocular 1 is housed in the case 16 according to the present invention, its entire structure is housed in the case 16 except the junction 4 and the holding member 6 which remain visible.
In this way, to remove the binocular 1 from the case 16, it is sufficient to grip the binocular 1 at the junction 4, preferably at the first and third parts 4A, 4C junction 4.
FIG. 7 illustrates the binocle 1 illustrated in FIG. 3 and therefore comprises all the elements which have been described for this figure except that the connecting means 7 are in the form of 6 buttons arranged on the first and second borders 2A, 2B,
It has been found that this embodiment makes it possible to hold the holding member 6 sufficiently without limiting its movement from the front to the back, and vice versa, relative to the binocle 1. This is advantageous for the user because the binocle 1 according to the invention has an improved maneuverability compared to the state of the art.
The sale of the binocular 1 according to the invention will preferably provide a binocular 1 and at least three holding elements 6 of different colors. In this way, the user can choose the element of maintenance that he wishes.
