Description

OPTICAL INSERT FOR MASK

The present invention relates to an optical insert for use within a mask and to be converted into a conventional bezel.

A ski mask, motorcycle or even free fall can tolerate the wearing of eyeglasses, which is not the case for a full face respirator with a screen, a diving mask, or even a diver's mask that require well heard to be waterproof.

The wearing of prescription glasses in a ski mask presents an increased risk of injury in the event of a fall by the presence of branches or even platelets. It is very unpleasant to damage his daily eyeglasses during a sport or during the execution of his work. The price of a frame and glasses can be very expensive according to the corrections and the treatments of these last ones. It is also unpleasant to be handicapped for several days for the ordering and the realization of a new pair of glasses, or at least having to return regularly to the optician to settle them.

Wearing prescription glasses when practicing sports, especially mountain bikes or motorbikes, causes abnormal wear, premature aging of the frame and lenses, due to the presence of sweat or projection of external elements, such as mud and dust.

It is of course possible to wear contact lenses for the practice of a sport, but it is not easy to put back or reposition a lens in the mountains, moreover in bad weather or when practicing activity. underwater.

In order to solve the aforementioned drawbacks, many optical inserts are commercially available. The majority of these optical inserts are kept close to the visor of the mask in which it is placed. This positioning is not suitable for obtaining good vision, as explained below.

To make a pair of glasses, it is recommended that the prescription is correct, that the glasses used are faithful and adapted to the prescribed prescription, that the glasses are perfectly centered in the glasses and that the glasses are well adjusted on the face of the glasses. 'user.

Note that a correction of a glass is prescribed for a standardized glass-eye distance of 13 millimeters and a standardized dihedral angle of 5 degrees between the average plane of a glass and the plane of the front face of a pair of glasses. or even having a slight curvature, so that the front face of a pair of glasses is almost flat.

It should also be noted that glasses are produced according to the user's morphology, such as pupillary distance and pupillary height. The optician therefore determines the optical center of the glasses on the nose of the user, by measuring the positioning of the pupils relative to the positioning of the frame on the face of the user. This positioning of the optical center is achieved by lateral and vertical measurements of the pupils on the glasses, as well as a measurement of the glass-horny distance.

A positioning of an optical insert against a visor is therefore not optimal, on the one hand because the shape of the insert matches that of the visor, the optics therefore have a dihedral angle between the average plane of a glass and the plane of the frontal face, important, and secondly because the glass-eye distance is not respected according to the prescription, these inserts are therefore removed from the eye of the order of 30 millimeters.

Thus, a large dihedral angle between the average plane of a glass and the plane of the front face, of an optical insert, accumulated with a distance glass-distant eye, causes a deformation of the important vision.

In the case where the glasses of an optical insert would be produced centered according to its positioning in a mask model, set on the face of the user by a conscientious optician, the glass-eye distance would not be respected in any case and this even optical insert would certainly not be suitable for another mask model having a different shape so a different face positioning.

This positioning against the visor also limits the ventilation around the lenses, which promotes the formation of mist. It is also important to note that the majority of commercially available optical inserts are narrower than a common pair of spectacles, which implies, given their positions in the mask, that compared to the standard glass-eye distance, the visual field is significantly reduced, which increases the discomfort of these devices.

Note also that commercially available optical inserts are positioned according to the type and shape of the mask used, and not according to the morphology of the user's face, as for a common pair of glasses. These positions facing the visor of a mask and not according to the morphology of the user can ensure proper optical centering of the glasses relative to the eyes of the user.

The present invention thus proposes a new type of optical insert, making it possible to overcome the aforementioned drawbacks.

Thus, the optical mask insert according to the invention comprises a front face which comprises a structure adapted to receive glasses and at least one retaining profile extending from the periphery of the front face towards the outside, namely intended to extend towards the inner periphery of the structure of a mask, while it comprises a nasal support.

According to a preferred embodiment, the nasal support is a nose-bridge.

According to one embodiment, at least one holding profile is connected to the structure by a removable fixing means.

According to features, at least one holding profile extends from the upper end or from at least one of the lateral ends of the end face.

Let us add that an average plane of a glass and the average plane of the frontal face make a dihedral angle between 0 and 15 °.

Note that the average plane of at least one retaining profile and the mean plane of the end face make a dihedral angle between 0 and 45 °, preferably between 0 and 30 °, more preferably between 0 and 15 °, while the mean planes of the profile and the front face intersect on one end of the front face.

According to one embodiment, the structure is partially circled, namely intended to surround a portion of the upper periphery and a portion of the inner periphery of a glass facing the nose.

Note that the front face has a radius of curvature of between 15 and 45 centimeters, preferably between 20 and 30 centimeters, said radius of curvature being perpendicular to the mean plane of the front face.

According to a preferred embodiment, the retaining profile is composed of two longitudinal sections extending from the upper center of the structure upwards.

It should be added that the invention also relates to a kit comprising the optical insert according to the invention, with branches or a branch system comprising a fastening means corresponding to that of the front face. Other features and advantages of the invention will become apparent from the description which follows with reference to the accompanying drawings which are given by way of non-limiting examples.

Figures 1 to 4 are views of the optical insert according to the invention, according to one embodiment.

FIG. 1 is a rear view,

Figure 2 is a sectional view along A-A of Figure 1.

Figure 3 is a top view.

Figure 4 is a rear view, the holding profile being disengaged.

Figures 5 and 6 are views of an optical kit comprising a front face of the optical insert according to the invention / a holding profile and a branch system.

Figure 5 is an exploded rear face view of the optical kit.

Figure 6 is a rear view of a front face of the optical insert according to the invention, assembled to a branch system.

Thus, an optical insert (1) according to the invention is intended to be inserted in a mask, advantageously maintained at the inner periphery of the mask structure, by at least one holding profile (5) advantageously adapted to the type of mask. mask used, while it is adapted to rest on the nose of the user by the presence of a nasal support (6).

In other words, an optical insert (1) according to the invention comprises a front face (2) equipped with a structure (3) adapted to receive glasses (4) and at least one retaining profile (5). extending from the periphery of the end face (2) and intended to be directed towards the inner periphery of the structure of a mask, preferably intended to extend advantageously in the direction of the upper end of a mask or intended to to extend towards the lateral ends of a mask, while it comprises a nasal support (6).

It is understood that in the following description, the optical insert (1) according to the invention is in the use position, namely the upper end of the front face (2) directed upwards, while the nasal support (6) is directed downwards.

Note that a nasal support (6) includes a nose-saddle, a pair of pads, or overinjection or a molded portion adapted to rest on the nose, at the bridge of the structure, preferably a nose-saddle that marries uniformly the shape of the nose.

The presence of the nasal support (6) makes it possible to position the front face (2) of the optical insert (1) according to the invention, in an equivalent way, even identical to the positioning of a front face of a conventional pair of spectacles on the face of the user.

This particular positioning for an optical insert makes it possible to place the lenses optimally or even perfectly in relation to the eyes of the user, respecting the optical centering of the lenses, at least at a glass-eye distance close to or equal to the value standard of 13 millimeters.

Remember that the optical center of a glass is made according to the structure of the front face (2) and the morphology of the user.

In the case of the invention, the optical centering of the glasses (4) to be positioned in the structure (3) of the front face (2) is thus formed according to the shape of the structure (3) of the front face (2). ) and the morphology of the user, and not according to the form or type of mask used.

Thus, once the glasses (4), adapted to the user, positioned on the front face (2) of the optical insert (1) according to the invention, the latter can be used in different models, types or forms of mask, without having to change the lenses or having to keep a mask model especially for glasses adapted to the user.

According to one characteristic, the front face (2) has a radius of curvature of between 15 and 45 centimeters, preferably between 20 and 30 centimeters, said radius of curvature being perpendicular to the mean plane (B) of the end face (2).

According to the preceding characteristic, a radius of curvature close to, or even equivalent to, or equal to that of a front face of a common sight glass, does not cause any distortion of the vision, according to the prescription glasses.

In other words, the optical insert according to the invention has a dihedral angle between the mean plane of a glass (4) and the mean plane (B) of the front face (2) between 0 and 15 ° .

The structure for receiving glasses, an optical insert is commonly circled, namely is intended to surround the entire periphery of the glasses.

The structure (3) of an optical insert (1) according to the invention can be rimmed, half-rimmed or even partially rimmed.

A half-circled structure (3) is intended to surround substantially half of the periphery of a glass (4), namely to surround three sides of a glass (4), in general the entire upper periphery and a part of the outer periphery, as well as part of the inner periphery of a glass, in correspondence of the nose.

A structure (3) half-circled or partially circled uses a lens fixing technology at its periphery by a wire of synthetic or metallic material, commonly called "Nylor" assembly.

A structure (3) rimmed or half-rimmed does not allow in most cases to change the size of glasses according to the size of a face.

According to the illustrated embodiment, the structure (3) of the optical insert (1) according to the invention is partially encircled, ie is intended to surround an upper part, as well as an inner part of the periphery of the glasses ( 4).

According to the previous embodiment, the specific form of the structure (3) makes it possible to modulate the size and shape of the glasses (4) according to the size of the user's face, namely a man, a woman , or even a child.

Recall that the optical insert (1) comprises at least one holding profile (5) which extends from the periphery of the end face (2) to the inner periphery of the structure of a mask.

According to one embodiment, at least one holding profile (5) extends from the upper end (2a) of the end face (2), namely from the upper end of the structure (3), towards the high, namely intended to extend towards the upper periphery of a structure of a mask.
