Description

Title of the invention: Eye protection mask Technical field of the invention

[0001] The invention relates to an eye protection mask intended to protect the eyes, such as a ski mask. The eye protection mask is particularly intended to protect the eyes against sunlight and / or against projectiles during sporting activities. The invention relates in particular to an eye protection mask of the "frameless" type, that is to say, an eye protection mask comprising a screen covering a frame arranged behind the screen. Prior art

[0002] To protect the eyes from the sun and / or from projectiles during an activity, it is common to wear eye protection equipped with a transparent or translucent protective lens. Wearing such a mask is particularly recommended for snow sports such as skiing or snowboarding, but also for mountain biking, motorcycling, or activities involving high-speed projectiles, such as shooting. Such a mask fits snugly against the face around the eyes and thus provides particularly effective eye protection.

[0003] Frameless eye protection masks, commonly referred to by the English term "frameless," are known in particular. Such masks comprise a protective screen covering the front of a frame arranged behind the screen. Thus, from a frontal view, that is, when looking at the wearer of such a mask face to face, the frame is completely hidden behind the screen, and only the screen is visible. Such a mask offers an enlarged field of vision and has a distinctive aesthetic appearance. Publication WO2012178049A1 discloses such a mask.

[0004] Attaching such a protective screen to the frame is complex. In particular, the prior art fastening methods for attaching the protective screen to the frame are relatively bulky. Consequently, the protective screen is positioned quite far from the face to allow sufficient space for these fastening methods. This negatively impacts the aesthetic appearance of such masks and their field of vision. Furthermore, the prior art fastening methods are relatively fragile and can be easily damaged, for example, during handling of such a mask or if the user falls. The screen could then detach from the frame accidentally or unintentionally, exposing the user's face to the external environment, potentially causing injury. Presentation of the invention

[0005] The object of the invention is to provide an eye protection mask that remedies the above disadvantages and improves upon known eye protection masks of the prior art.

[0006] More specifically, a first object of the invention is a frameless eye protection mask that is particularly robust, compact, and simple to manufacture. Summary of the invention

[0007] The invention relates to an eye protection mask comprising a frame and a screen system attached to the frame, the screen system comprising a first screen and a support attached to the first screen, the first screen covering the front of the frame and the support, the support comprising: - a front surface fixed against a rear face of the first screen, - a retaining surface extending substantially parallel to the first screen at the rear of the first screen, the retaining surface and an outer edge of the first screen together forming a radial groove cooperating with the mount to retain the screen system to the mount.

[0008] The support may further include a rear surface extending opposite the mount, the retaining surface extending between the front surface of the support and the rear surface of the support.

[0009] The mount may include a radial groove, the retaining surface being inserted into the radial groove.

[0010] The retention surface can extend along at least 50%, preferably at least 80%, of an outer edge of the screen.

[0011] The retaining surface may include at least one notch, and the mount may include at least one protrusion of a shape complementary to the shape of at least one notch, the at least one protrusion being fitted into at least one notch.

[0012] At least one notch may include a narrowed entry.

[0013] At least one notch may include: - at least one initial notch formed on a portion of the retaining surface intended to extend around the nose, - at least one second notch formed on a portion of the retaining surface intended to extend opposite a cheekbone, and - at least a third notch formed on a portion of the retention surface intended to extend opposite the front.

[0014] The retention area can extend at least: - in a lower part of the support designed to extend opposite the cheekbones and around the nose, - in an upper part of the support intended to extend opposite the forehead, - in a left lateral part of the support intended to extend opposite an outer side of the left eye, and - in a right lateral part of the support intended to extend opposite an outer side of the right eye.

[0015] The frame may be more deformable than the screen system, only the frame being intended to deform in order to assemble or disassemble the screen system to the frame.

[0016] The mask may include an elastic band configured to hold the eye protection mask on a person's head, the elastic band being attached to the frame.

[0017] The entire outer edge of the first screen can be seen from outside the mask.

[0018] The screen system may include a second screen extending parallel to the first screen at the rear of the first screen, the second screen being held by the support. Presentation of the figures

[0031] Figure 1 illustrates an eye protection mask 1 according to an embodiment of the invention. The eye protection mask 1 is intended to protect the eyes from the sun and / or projectiles during the practice of a sporting activity such as a snow sport like alpine skiing or snowboarding, mountain biking, motorcycling, or an activity in which high-speed projectiles are used, such as shooting. When used for snow sports, such a mask may be called a "ski mask".

[0032] The eye protection mask 1, hereafter referred to simply as "mask 1", comprises a transparent or translucent protective screen 2 through which a user can observe the environment. The screen 2 thus extends into the field of vision of a mask wearer, and in particular with respect to both of the user's eyes. The screen 2 may, in particular, be tinted to darken the perception of the environment and thus protect the mask wearer from sunlight. Alternatively, the screen 2 may be transparent to simply protect the eyes from splashes without darkening the perception of the environment. The screen 2, which may also be called "lens", is preferably made of plastic, in particular polycarbonate.

[0033] The mask 1 is of the "frameless" type. Only the lens 2 is directly visible when the mask 1 is viewed from the front, i.e., from the perspective of [Fig. 1]. The mask 1 therefore preferably comprises a smooth front surface, not locally covered by any part of the frame or any other structural element intended to hold the lens. The mask 1 thus does not include any folds or recesses on its front surface at the interface between the lens 2 and such a structural element. This prevents particles from accumulating in such recesses. The lens 2 is therefore particularly easy to clean and offers a distinctive aesthetic appearance.

[0034] As an aside, assuming that the screen 2 is sufficiently transparent, it is still possible to distinguish components of the mask 1 other than its screen 2 by looking through the screen. A mask of which part of the frame is visible, in front view, only through the screen 2 is nevertheless considered a "frameless" mask within the meaning of the invention.

[0035] The mask 1 is intended to be placed against the face around the eyes. According to the front view as shown in [Fig. 1], the screen 2 comprises a roughly rectangular shape with a notch to fit around the nose. The screen 2 comprises an outer edge 3, or contour 3, formed in particular by: - ​​an upper edge 4 extending opposite the forehead, - two lower edges 5A, 5B on either side of the notch contouring the nose, and extending opposite the cheekbones, and - lateral edges 6A, 6B extending substantially vertically on the sides of the eyes. Preferably, at least 80% of the outer edge 3 of the screen, or even at least 90% of the outer edge 3 of the screen, could be visible. According to the embodiment presented, the outer edge 3 of the screen 2 is fully visible from outside the mask 1, that is to say, 100% of the outer edge 3 of the screen is visible and not covered by a structural element of the mask.

[0036] According to a top view, illustrated in [Fig. 2], it can be seen that the mask 1 has a rounded shape, designed to conform to the shape of the head and face of the wearer of the mask. In general, the screen 2 can, for example, have the shape of a portion of a cylinder of revolution, or even the shape of a portion of a sphere.

[0037] The longitudinal axis X is defined as the line of sight of a mask wearer when looking straight ahead. The longitudinal axis is a horizontal axis, oriented from back to front. The vertical axis Z is defined as the axis along which a mask wearer extends when standing upright. The vertical axis Z is perpendicular to the longitudinal axis X. The vertical axis Z is oriented from bottom to top. Finally, the transverse axis Y is defined as the axis perpendicular to the X and Z axes, and oriented from left to right from the viewpoint of a mask wearer 1. The X, Y, and Z axes form an orthogonal coordinate system. For a given point P on the outer edge 3 of the screen 2, the radial axis R is defined as the axis that is both parallel to the screen 2 at the point P considered and perpendicular to the outer edge 3 at the point P. The radial axis R is oriented in a centrifugal direction.

[0038] As can be seen in Figures 2 and 3, the mask 1 comprises a frame 7 supporting the screen 2. The frame 7 is equipped with an elastic band (not shown) intended to pass behind the head or behind a helmet to hold the mask 1 against the wearer's face. The elastic band has a first end attached to a left edge of the frame 7 and a second end attached to a right edge of the frame. More specifically, the frame 7 comprises a body 8 and two fastening means 9, left and right, cooperating with the two ends of the elastic band. The two fastening means 9 are integrated into the body 8. The elastic band passes through the body 8 via two slots 10, left and right, provided for this purpose. The frame 7 advantageously includes a circumferential support surface 11, made of a flexible material capable of deforming upon contact with the face. As explained previously, the frame 7 is frontally covered by the screen 2. By "frontally" we understand that the frame 7 is covered by the screen when viewed from the front.

[0039] Advantageously, the frame 7 also includes ventilation means 12, for example in the form of one or more grilles, fixed to the body 8 or formed directly in the body 8. The ventilation means 12 can, for example, be arranged at the level of an upper and / or a lower part of the frame 7, between the screen 2 and the support surface 11. The ventilation means 12 prevent the formation of fog on the screen 2.

[0040] The frame body 8 of the frame 7 is advantageously made of a flexible and elastic material. The bearing surface 11 can thus be formed directly on the frame body 8. The frame body 8 can therefore be designed to rest directly against the face. Alternatively, the bearing surface 11 can be formed in a separate element from the frame body 8 and attached, for example, by gluing, to the frame body 8. Such an attached element can, for example, be made of foam or fabric.

[0041] According to one embodiment, the body 8 of the frame may be made of thermoplastic polyurethane (TPU). The material constituting the body may have a hardness between 80 and 90 Shore A measured according to ASTM D2240.

[0042] A means of attaching the screen 2 to the mount 7 is now described according to an embodiment of the invention, with reference to Figures 4 to 10. The screen 2 is attached to the mount 7 by means of a screen support 13, hereafter referred to simply as "support 13". The support 13 is illustrated in [Fig. 4]. The screen 2 is illustrated in [Fig. 5]. The assembly formed by the screen 2 and the support 13 is called the "screen system 14". The screen system 14 is illustrated in [Fig. 6]. In particular, the screen 2 is attached to an external face of the support 13. The screen 2 can thus be described as the external screen.

[0043] The screen 2 covers the front not only of the mount 7 as explained previously, but also of the support 13. Thus, the support 13 does not extend radially beyond the outer edge 3 of the screen. The support 13 is therefore invisible when viewed from the front from outside the mask 1, or only visible through the screen 2. As we will see later, the support 13 is also invisible when observing the mask 1 from the sides since it is covered by the mount 7. The support 13 has a general shape that largely follows the shape of the outer edge 3 of the screen 2. The support 13 includes, in particular, a closed line delimiting a central opening closed by the screen 2. According to the embodiment shown, the line followed by the support 13 is uninterrupted and therefore follows the entire outer edge 3 of the screen. According to one embodiment, the support could extend only along a portion of the outer edge 3 of the screen 2, preferably over at least 50% of the length of the outer edge 3, or even at least 80% of the length of the outer edge 3. According to another embodiment, the support 13 could be formed of several support elements, separated from each other along the outer edge 3 of the screen 2.

[0044] The support 13 is preferably a single-piece element, preferably made of plastic, for example, a plastic element obtained by molding. The support 3 may be made of a thermoplastic polymer such as acrylonitrile butadiene styrene (ABS), polycarbonate (PC), or a mixture of these two materials.

[0045] The support 13 is attached to the screen 2. In particular, the support 13 comprises a front surface 15 fixed against a rear face 16 of the screen 2. Preferably, the front surface 15 of the support 13 is bonded to the rear face 16 of the screen 2. According to one embodiment, the support 13 and the screen 2 could be attached together differently, for example by interlocking or by welding. Alternatively, the support 13 and the screen 2 could even form a single monolithic part.

[0046] A first zone ZI of the rear face 16 of the screen 2, against which the front surface 15 of the support 13 is fixed, is identified by dashed lines in [Fig. 5]. This first zone ZI is located from the outer edge 3 of the screen 2 by a non-zero distance DI, for example, at least 5 mm. Between the first zone ZI and the outer edge 3 of the screen 2, the rear face 16 includes a second zone Z2. The second zone therefore has a non-zero width. The screen rests directly against the mount 7, in particular against the body 8 of the mount 7, via its second zone Z2. The second zone Z2 of the screen 2 thus makes it possible to mask the mount 7 in the front view of the mask 1. In other words, the second zone Z2 of the screen covers at least part of an outer face of the mount.

[0047] Figure 7 illustrates, by means of a cross-sectional view along a median plane PM, a part of the Screen system 14. The median plane PM is identified in [Fig. 6]. It is a plane parallel to the X and Z axes, passing through a center of the mask 1. The front surface 15 of the support 13 includes a recessed area 18 framed by an inner rim 19 and an outer rim 20. The rims 19 and 20 rest directly against the rear face 16 of the screen 2. The recessed area 18 creates a free volume 21 between the rear face 16 of the screen 2 and the support 13. This free volume 21 is designed to receive adhesive for attaching the screen 2 to the support 13. This allows the surface of the screen receiving adhesive to be contained, thus preventing adhesive from leaking onto a useful area of ​​the screen. Advantageously, the edges 19 and 20 rest against the screen along its entire perimeter, without interruption. The bead of adhesive used to fix the support 13 to the screen 2 thus follows a closed and continuous line.This improves the stability of the 13 support on the screen. 2. Alternatively, a self-adhesive strip, for example a self-adhesive seal, could be placed in the recessed area 18, between the screen 2 and the support 13. According to one embodiment, the front surface 15 could include discontinuities. As a note, the screen 2 can advantageously be tinted at least in the areas Z1 and Z2 in order to conceal the support 13 and the mount 7.

[0048] The support 13 also includes a retaining surface 23, extending parallel to the front surface 15, and offset rearward relative to the front surface 15. The retaining surface 23 also extends parallel to the screen 2. The retaining surface 23 cooperates with the mount 7, in particular with the body 8 of the mount 7, to retain the screen system 14 to the mount. In particular, a reaction force of the retaining surface 23 against the body 8 of the mount 7 prevents the screen system 14 from detaching from the front of the mount 7.

[0049] The retaining surface 23 extends further to the rear than the front surface 15. Thus, a radial groove 22 is formed between the retaining surface 23 of the support 13 and the outer edge 3 of the screen 2. As will be seen later, the body 8 includes a front wall 28 inserted inside this radial groove 22. Notably, the arm of the radial groove 22 formed by the screen 2 is taller than the arm of the radial groove 22 formed by the support 13. This allows the screen 2 to fully cover not only the support 13 but also the mount 7.

[0050] According to another approach, the support 13 comprises a base 24 fixed to the screen, and a wing 25 extending from the base 24 parallel to the screen 2 towards the outer edge 3 of the screen. The wing 25 thus extends radially in a centrifugal direction. The base 24 comprises the front surface 15 of the support, and the wing 25 comprises the retaining surface 23.

[0051] The retaining surface 23 extends along the outer edge 3 of the screen, preferably along at least 50% of the length of the outer edge 3 of the screen, or even at least 80% of the length of the outer edge 3 of the screen. The more the retaining surface 23 extends along a significant proportion of the outer edge 3 of the screen, the better the retention conferred by the interaction of this retaining surface with the mount 7. In one embodiment, the retaining surface 23 extends 360° around the screen 2. A retaining surface extending along a significant proportion of the outer edge 3 of the screen thus makes it possible to consider a retaining surface with a low height along the radial axis R and / or the use of a more flexible and therefore more comfortable material for the body 8 of the mount 7.

[0052] Preferably, the retention surface 23 extends at least: - in a lower part 31 of the support intended to extend opposite the cheekbones and around the nose of a wearer of mask 1, - in an upper part 32 of the support intended to extend opposite the forehead of the wearer of the mask 1, - in a left lateral part 33 of the support intended to extend opposite an outer side of the left eye on the forehead of the mask wearer 1, and - in a right lateral part 34 of the support intended to extend opposite an outer side of the right eye of the forehead of the mask wearer 1. The screen system 14 is thus retained to the frame 7 on its various sides, which allows for a homogeneous and robust retention of the screen system 14.

[0053] The support 13 also includes a rear surface 26 extending opposite the mount 7, in particular opposite the body 8 of the mount 7. The rear surface 26 extends parallel to the screen 2. The rear surface 26 may be, at least locally, in contact with the mount 7. The rear surface 26 may also extend, at least locally, to a non-zero distance from the mount, as shown in [Fig. 8]. The distance D2 separating the front surface 15 from the rear surface 26 of the support may preferably be less than or equal to 5 mm, or even less than or equal to 3 mm. The support 13 is therefore particularly compact along the longitudinal axis X. The rear surface 26 and the retaining surface 23 of the support are two opposite faces of the wing 25. The rear surface 26 faces the rear of the mask 1, and the retaining surface 23 faces the front. The rear surface 26 is generally flat.In the event of an axial force exerted on the screen 2, a large contact area is thus obtained between the mount 7 and the support 13, and the support 13 is not at risk of being damaged.

[0054] As can be seen in Figures 8 and 9, the body 8 of the mount 7 includes a radial groove 27. The radial groove 27 extends parallel to the radial axis R around the entire circumference of the mount 7. This radial groove 27 is formed by a front wall 28 and a rear wall 29 extending parallel to the front wall 28. The wing 25 of the support 13 is inserted into the radial groove 27 of the mount. Thus, the support 13 is masked by the mount 7 on the sides of the mask 1. Since the retaining surface 23 of the support is formed on the wing 25, the retaining surface 23 is therefore also inserted into the radial groove 27 of the mount.

[0055] A front face of the front wall 28 of the mount bears, or is capable of bearing, against the second zone Z2 of the rear face 16 of the screen 2. A rear face of the front wall 28 bears, or is capable of bearing, against the retaining surface 23 of the support. Advantageously, the thickness of the front wall 28 is substantially equal to the distance separating the retaining surface 23 of the support from the rear face 16 of the screen. A front face of the rear wall 29 bears, or is capable of bearing, against the rear surface 26 of the support. The radial groove 27 advantageously has a constant width around the perimeter of the mount 7.

[0056] With reference to Figures 4, 6, and 9, it can be seen that the retaining surface 23 of the support comprises a set of notches 35. The body 8 of the mount 7 comprises a set of protrusions 36 whose shape complements the shape of the notches 35. Each protrusion 36 of the mount is thus fitted into a notch 35 of the support. This improves the retention of the screen system 14 to the mount 7. The notches 35 are local interruptions in the retaining surface 23, and indeed the only interruptions in the retaining surface 23. The protrusions 36 are arranged at the bottom of the radial groove 27, specifically between the front 28 and rear 29 walls of the mount.

[0057] All the notches 35 can have identical shapes and all the protrusions 36 can have identical shapes. In particular, as illustrated in [Fig. 10], each notch 35 advantageously includes a narrowed inlet 37, that is, an inlet 37 narrower than the bottom 38 of the notch 35. The engagement of the protrusion 36 inside the notch 35 thus requires elastic deformation of the protrusion 36 and / or the notch 35. Such a device further improves the retention of the screen system 14 on the frame 7 without compromising the overall size of the mask 1.

[0058] According to the embodiment presented, the retaining surface 23 comprises seven notches 35 spaced apart from each other. Four notches are formed in the lower part 31 of the support and three notches are formed in the upper part 32 of the support.

[0059] More specifically, support 13 comprises: - a first notch 35A formed on a portion of the retention surface intended to extend around the nose, particularly to the right of the nose of the mask wearer, - a second notch 35B formed on a portion of the retention surface intended to extend opposite the right cheekbone of the mask wearer, - a third notch 35C formed on a portion of the retention surface intended to extend opposite the forehead, notably substantially above the right eye of the mask wearer,

[0060] - a fourth notch 35D formed on a portion of the retention surface intended to extend opposite the forehead, particularly above the nose, - a fifth notch 35E formed on a portion of the retention surface intended to extend opposite the forehead, particularly substantially above the left eye of the mask wearer, - a sixth notch 35F formed on a portion of the retention surface intended to extend opposite the left cheekbone of the mask wearer, and - a seventh 35G notch formed on a portion of the retention surface intended to extend around the nose, particularly to the left of the nose of the mask wearer. Body 8 comprises seven protrusions 36 positioned opposite the seven notches.

[0061] Alternatively, the number of notches 35 and the corresponding number of protrusions 36 could be different. Preferably, the mask comprises between five and ten notches and the same number of corresponding protrusions, so as to obtain good retention of the screen system 14 to the mount 7, while maintaining a simple assembly between these two elements.

[0062] The screen system 14 is advantageously attached to the frame 7 in a removable, i.e., reversible manner. In particular, the screen system 14 can be assembled and disassembled from the frame 7 by the user of the mask 1 without the use of any tools. Advantageously, the mask 1 can be supplied with several screen systems 14 of identical shape. Such screen systems can be distinguished from one another by the opacity of their screen (for example, to adapt to different climatic or visibility conditions) and / or by their aesthetic appearance, or even be identical to each other so as to serve as replacement parts. Screen systems 14 can also be marketed independently of the frame 7 to allow mask users to replace their screen.

[0063] Advantageously, the frame body 8 of the frame 7 is more deformable than the screen system 14. In particular, the frame body 8 of the frame 7 may be made of a less rigid plastic material than the plastic material used for the support 13. The screen system 14 can be considered a rigid assembly compared to the frame body. Thus, only the frame 7 is designed to deform in order to assemble or disassemble the screen system from the frame. The flexibility of the frame body 8 of the frame 7 is therefore used both to provide comfortable support for the frame 7 on the face and to allow the assembly and / or disassembly of the screen system 14. For example, the frame body 8 may have a tensile strength of 40 MPa or less according to ASTM D412. The support 13 may have a tensile strength of 50 MPa or more according to ASTM D638.

[0064] Figure 11 illustrates an embodiment in which the mask 1 includes a second screen 40. The second screen 40 can be attached to the support 13, at the rear of the previously described screen 2, referred to as the "first screen 2". The second screen 40 preferably extends parallel to the first screen 2, at a non-zero distance from the first screen 2. An air gap is thus formed between the first and second screens. This air gap acts as a thermal barrier and prevents fogging in the mask 1. The first screen 2 therefore constitutes a front screen, and the second screen 40 constitutes a rear screen.

[0065] The support 13 advantageously comprises a bearing surface 41 (identified in [Fig. 8]) extending around a rear periphery of the support 13, against which the second screen 40 is fixed, for example by gluing. The bearing surface 41 is formed on a rear face of the base 24. The bearing surface 41 is recessed forward relative to the rear surface 26 described previously. A rear face of the second screen 40 can thus extend substantially in line with the rear surface 26. The body 8 of the mount may optionally include a tab 42 covering an outer edge of the second screen. The second screen 40 can be fixed to the support 13 by means of glue or by means of an adhesive tape 43 such as a self-adhesive strip as shown in [Fig. 11]. Thus, the support 13 serves not only to hold the first screen 2 but also the second screen 40.The second screen 40 has a surface area strictly smaller than the surface area of ​​the first screen 2. The first screen 2 extends more radially than the second screen 40.

[0066] Finally, thanks to the invention, we have a simple eye protection mask 1 that is easy to manufacture and use. The means for attaching the screen system 14 to the frame 7 extends radially and is thus particularly compact in the axial direction. This allows the screen 2 to remain close to the face and provides a wide field of vision.
