Abstract

The versatile glasses (or goggles) are fitted with means for adjusting and/or aligning the attachment fittings comprising essentially at least one swivelling adjustment module (7) connected on one side (9) to the frame itself (1) of the optical components (2, 3) and on the other side (12, 13, 14, 24) to at least one attachment fitting (10) adjustable in length and/or direction.

Description

Modular goggles / mask with means for adjusting and / or orienting the attachments without tools.

The present invention relates to modular goggles / mask provided with means for adjusting and / or orienting the fasteners.

In the prior art, glasses have already been produced, the lenses of which are assembled on a frame provided with lateral fasteners, such as for example two lateral branches.

In this technique, the branches are attached directly on hinges to the frame which carries the lenses or optical elements for visual correction and / or eye protection. But, especially in the field of sports and leisure where particularities are linked to each, and also in traditional eyewear, where we have seen the appearance of fashion issues, the number of models that a manufacturer must present to its catalog has grown considerably.

In addition, at the level of each user, it is not uncommon that the latter must have several pairs of glasses, or that he wishes to change the aesthetics of these with fashion, or that he wishes to add optional devices according to the activities or sports he practices.

It is an object of the present invention to provide a means for making a base of glasses modular.

On the other hand, the glasses must be adapted to the conformations of the wearers, but also for the same wearer, to the particularities, for example, of the sport which he practices, knowing that he can practice several of them.

For example, in downhill skiing, the position of the goggles attachments is

REPLACEMENT SHEET chosen on the top of the skull while in slalom, we prefer to have ties under the occiput. In general, the glasses attachments are constituted either by branches at least partially rigid in a longitudinal direction or adjustable telescopically or by a strap, or braid, elastic and flexible which surrounds the rear area of the wearer's skull. In the prior art, the length adjustment of the fasteners is generally ensured by folding or bending the flexible end of the branches of the goggles / masks or telescopically adjustment, or else, by sliding a retaining loop on a strap or braid passing in duplicate on the frame or by CORDAT type retainer (which surrounds the ear to the lower part of the lobe).

However, this adjustment by deformation is unsatisfactory, since it requires for example to remove the glasses and therefore does not allow adaptation according to the situations. On the other hand, the deformations straighten over time and the adjustment can completely mismatch during a sports exercise, which is detrimental. It is an object of the invention to provide a means of adjusting and / or orienting the fasteners without requiring the intervention of either a technician or a tool. In particular, in one embodiment of the invention, the adjustment can even be carried out by the user without removing the glasses or the mask. It is another object of the invention to ensure the folding of the face constituted by the bi-ocular strip without added hinge element, as is the case in the case of frames existing on the market. In this case, certain glasses accessories provided in the invention are also provided with folding means making it possible to reduce the storage volume. It is another object of the invention to remedy disadvantages of the prior art, in particular with regard to the adjustment in length and / or in orientation of the fasteners of the spectacles.

In fact, the present invention relates to modular glasses / masks provided with means for adjusting and / or orienting the fasteners. The invention is characterized in that these means mainly comprise at least one adjustable adjustment module removably linked on one side to the frame itself and on the other hand to at least one fastener adjustable in length and / or direction .

- Figure 14: a perspective view of the adjustment module of Figure 13.

In Figure 1, there is shown a general exploded view of mounting glasses, in an embodiment permitted by the means of the invention. The glasses, also called masks, mainly comprise a frame 1 provided with optical elements 2 and 3, here constituted by protective glasses against the sun and the bad weather. Each optical element is provided with connection means 4 and 5 with an adjustable adjustment module 6 and 7. The adjustable adjustment module 7 comprises fixing means 8 of at least one clip 10a and which are intended to allow to bring together or to move aside the fastener 10a from a reference point of the module. In the rest of the text as well as in the claims, it should be understood that in certain embodiments, the frame can be constituted by another element of the glasses such as the optical element or elements or by an accessory such as a visor. However, for convenience, the term frame has been used to designate in the glasses or mask the junction part between the elements (or the optical element) and the fasteners.

In the embodiment of FIG. 1, the fixing means 8 consist of fixing holes 12, 13, 14

REPLACEMENT which allow the fastener to be brought together or apart which can thus be of constant length. It is possible in this way to adjust the length of the branch which constitutes the fastener 10a, by selecting one or the other of the holes 12, 13 or 14.

The module 7 consists of a molded plastic part, made of a rigid plastic. It is possible to give it forms as varied as possible, in particular chosen according to fashion or use requirements, for example in the case of sports protective glasses or professional protection.

In addition, the adjustable adjustment module 7 has on one side or edge, removable fixing means 9 intended to be adapted to the fixing means of the frame 1 or of the optical element itself.

In Figure 1, other possible fasteners are shown. The optional fastener 11 is constituted by an elastic cord 14 of circular section in the example of FIG. 1.

In general, the fasteners intended for the adjustable adjustment module 6 or 7 are interchangeable and comprise a connecting means constituted by a screw 16 or 17 made of a plastic material, which is fixed on a fixed part 19 or 20 and the threaded end of which protrudes from the assembly 21 or 22 enters one of the fixing holes of choice 12,13, or 14.

Note that the screw head consists of a knurled button 24 disposed inside the glasses, once they are worn by the user. Therefore, no protruding longitudinal part presents a risk in the event of a fall for the user.

On the other hand, the assembly is made in various shades of plastic materials depending on the area or the function of the element. It will be noted here that one of the merits of the invention is to overcome the need to use

REPLACEMENT SHEET metal parts as was the case in the prior art for the connecting or joining parts in particular.

The connection between the fastener and the adjustable adjustment module is provided with means making it possible to stabilize the adjustment of the orientation of the fastener with respect to a reference direction of said adjustable adjustment module. In FIG. 1, it can thus be seen that the vertical face opposite the adjustment module 6 of the fixing means 21 or 22 carries radial notches on a determined angular sector around the axis of the fixing screw. We also note that these radial notches are intended to cooperate with reciprocal notches arranged on the face opposite the module on which is fixed the fixing means considered. Here, due to the perspective representation, only the notches of the module 7 are visible, which engage with the reciprocal notches of the fixing means 16, 18 which are identical to those shown for the fixing means 21 or 22.

When the fixing screw is tightened in a fixing hole 12 or 13 or 14, the notches of the two facing surfaces make it possible to maintain the angular position chosen between the fastener and the adjustable adjustment module.

It is thus possible to adjust both in length and in direction the fasteners relative to the adjustment module

6 or 7.

This adjustment module also allows a removable fixing which makes it possible to exchange different attachments such as the arms 10 or the elastic cord 11.

Note in the drawing, that this concept of adjustment module makes it possible to make the glasses entirely modular.

In particular, it becomes possible to design around a swiveling adjustment module, and according to the embodiment of Figure 1, around two swiveling adjustment modules, a range of manufacturing or sales of

EMENT unique and transformable or modular glasses. We note that the gains in terms of manufacturing speed and costs will be considerable since on a single basis, it is now possible to create various designs of glasses.

In addition, the user can purchase a single base and add useful accessories that he was previously forced to buy on specialized glasses.

Thus, in Figure 1, the glasses can wear two different types of fasteners 10 or 11, as has already been described. However, the optical element 2, 3 can also be interchanged by using the adjustable adjustment modules 6 and 7. In particular, single-glass screens are provided which adapt to the place of the two-glass version shown in Figure 1. It will be noted here that, when the optical elements are constituted by screens, the glasses often take the name of mask.

Likewise, other optional accessories make it possible to compose at will a model adapted to the needs of the user. Note in Figure 1, arch supports 27 and 28 provided with anti-fog channels 29 and 30 to prevent fogging on the optical elements 2 and 3. An interchangeable nose support 32 is also provided which is mounted on the frame 1 removably so as to allow it to be adjusted in position, but also to choose shapes suitable for the user. The adaptation of an adjustable nasal support system makes it possible to adapt the glasses / mask to people of Asian type having a different morphology, without modification of the basic elements (at present, the glasses / mask intended for Asian countries have a nasal support, also called "nose pads", specific to the Asian type).

There are also facings 33 which are clipped onto the REPLACEMENT SHEET frame at the interface between the two optical elements 2 and 3. This interface in one embodiment constitutes a folding articulation which makes it possible, without added hinge element, to fold the glasses (or mask) in order to store them in a reduced volume .

There is also a visor 34 which is mounted above the frame 1. In a particular embodiment, the visor is fixed by clipping onto the existing leg support. In general, according to the invention, the visor fits on lateral protection elements 35 and 36 extended by ears which are intended to be superimposed on the adjustment modules 6 and 7. The lateral protections are of curved shape. so as to connect to the visor 34 which is in general direction in a horizontal plane with respect to the user with the ears which are in general direction in a vertical plane with respect to the user. The lateral protection element 35 is attached to the visor 34 in a removable and / or foldable manner by a hinge in two clipped elements: 37a on an edge of the lateral protection element 35 in the form of an open hook, and 37b on the edge opposite the visor 34 in the form of a cutout in which the hook engages, or vice versa, the elements coming from molding.

The lug 40 which extends the lateral protective element 35 comprises two enveloping and flexible tongues 48 and 39 which are intended to grip on both sides the adjustable adjustment module 7. This method of fixing makes it possible to improve the side protection of the user. In one of the embodiments of the invention, the visor is provided with articulation means in order to be able to fold and to allow its transport in a reduced bulk. Finally, on the lateral protective element 36, ventilation grooves 41 have been shown. They allow the lateral part of the glasses to be ventilated properly. which, in this embodiment, would otherwise be very closed. In Figures 2a to 2c, there are shown three views of an adjustable adjustment module 51 in the embodiment of Figure 1. Figure 2a is an interior side view, that is to say that there is shown the inner side which faces towards the head of the user. This face has a reference direction, represented by the longitudinal axis 50, around which the attachment linked to the module 51 can be oriented. Three holes 56, 57 and 58 make it possible to obtain three adjustment positions and there is shown, with an angle of 45 ° around the reference direction 50, the three notched sectors 53, 54 and 55 which allow the aforementioned angular adjustment.

In Figure 2b, there is shown a front view of the module

51, the edge of which is provided with a hinge 59 intended to come to be removed in a removable manner on the corresponding edge of the frame or directly from the optical element. In Figure 2c, there is shown a top view of the module 51 of Figure 2a, where the identical elements have the same references.

In Figure 3A, there is shown a perspective view of the module 51 in a possible embodiment of rigid molded plastic material. In FIG. 4a, another embodiment of an adjustment module according to the invention has been shown, which incorporates all of the aforementioned possible characteristics, and which adds to them a housing 60 formed on the external face of the module 61. In the housing 60, provision is made for snap-fastening or by locking a removable or non-removable member, which constitutes an additional accessory adapted to the glasses of the invention.

REPLACEMENT SHEET Indeed, in the prior art, it is known, in particular in the practice of certain sports, that assistance devices are necessary, but that they must be worn permanently by the user.

This is the case, for example, of detectors of people buried under an avalanche for skiers. However, there is a special problem which is not currently adequately resolved.

In this kind of sport, safety requires that each skier exposed to the risk of being buried under an avalanche, be equipped with a transponder or a transmitter activated at least after the triggering of the avalanche so that, even if the person is no longer active, the rescuers can identify them.

However, the main problem of this kind of so-called beacon or transponder solution (on radio frequencies or otherwise) is that the port must be permanent and separate and specialized devices are only rarely worn by skiers.

The solution of the invention is precisely to provide an attachment zone for this tag on the glasses themselves, which themselves are never forgotten, since the skier can in no case do without them. This solves the problem of integrating this accessory into its user, an integration that no technical means has so far easily allowed. In addition, the solution of the invention adapts to many other accessories, among which the following may be mentioned without limitation:

- the compass or altimeter for users wishing to have orientation instruments;

an information transmitter comprising a signal receiver transmitted by infrared or herzian channel or otherwise with a detector and a listener, the assembly being housed in the glasses of the invention. To this end, the invention has a housing of sufficient dimensions when it is practiced on the adjustable adjustment module, a solution which it is not possible to take in many other structures of glasses, which are too thin.

The housing 60, shown in a partial section in Figure 3b, comprises means for removable attachment of an accessory of the aforementioned type provided with reciprocal attachment means. Different solutions are possible among the solutions of the prior art that those skilled in the art will be able to adapt to the invention.

In Figure 3b, there is shown a housing 60 having a bearing edge 64 of the accessory, the housing 60 being of round shape, and a notch 62 making it possible to block the accessory, not shown, in rotation, of cylindrical shape corresponding.

The accessory can be glued or welded, if it is an accessory that does not need to be removable. Gluing or welding is carried out on the internal flange 62.

The accessory can be fixed by clipping between the flange 62 and a flange, not shown in flexible plastic, on the periphery at the exit from the housing 60. The accessory is forced in or out by elastic deformation.

The housing also has a flat bottom on which was made in the embodiment of Figure 3a, a groove or slot 63. This slot 63 allows in particular to evacuate the condensation entrained between the bottom of the inserted accessory and the bottom of the housing 60 and again to balance the pressures between the space provided between the bottom of the accessory and the bottom of the housing. This is the case, for example, in air sports or in mountain sports. In Figures 4a and 4b, there are shown adaptations of the housing 60 of Figure 3b. The housing 65 in Figure 4a or 4b is intended for a removable fixing called "quarter of

LOCATION SHEET tower ". Indeed, the cylindrical accessory is provided with a lug, the shape of which is intended to be fitted into the cutout 66 formed on the edge 67 of the housing 65. Under the edge 67, on both sides and d At the other of the cutout 66, a cavity is made in which the lug of the accessory must enter by rotation. At the end of this rotation, the accessory is fixed in the housing 65. It can be removed therefrom by turning the accessory of a reverse quarter turn. The axes of the reference direction 69, which is also taken as the cutting line for the view of FIG. 4b, have been reported in FIGS. 4a and 4b. the regular fixing means 70 aligned on this direction 69.

It is noted that in this embodiment the three holes of the means of the fixing means 70 open onto the external face of the adjustable adjustment module. Finally, there is also shown the removable fixing hinge 71 of the module.

In general, the glasses according to the invention comprise two adjustable adjustment modules on either side of the head of the spectacle wearer. It is therefore clear that the description of a single module does not limit the invention to glasses having only one adjustment module, but on the contrary, can be adapted, as described in Figure 1, to glasses comprising two adjustment modules, one on the right, the other on the left. It is thus clear that, if an accessory is to be inserted on a first adjustable adjustment module, the other adjustment module may or may not have a housing like the housing 60 or 65. If it has, then, two situations can present themselves: - the housing is unoccupied, and in this case, according to the invention the housing is removably closed by a cover not shown in the drawing which makes it possible to protect the opening of the housing from the outside; Moreover,

REPLACEMENT SHEET this cover can also be used to balance the weight of the accessory inserted in the first aforementioned module; - the accommodation and occupied by another accessory.

In Figure 5, there is shown another embodiment of a type of fastener comprising an elastic cord which encloses the skull of the user. Each end of the elastic cord 80 is introduced into a capsule 81 or 82 provided with cord locking means on the one hand, and on the other hand by means of attachment to the above-mentioned adjustable adjustment module.

In Figure 5, the first capsule 81 has been shown disassembled, and the second capsule 82 has been shown assembled.

Each capsule therefore comprises a screw provided with a head 83 and a threaded rod which penetrates into a box 85 provided with means for retaining the cord. When the screw 83, 84 is installed in the box 85, the end of the screw comes out of the capsule and can be used to fix one of the ends of the cord to a hole suitably chosen from the means for fixing the adjustable adjustment module described. especially in Figure 1.

In addition, the external face of each capsule is provided with a notched zone around the axis of the screw and of the screw hole in the box 85. These notches are intended to cooperate with the reciprocal notches arranged on the opposite face. of the module that corresponds to them. In this way, as has already been described, a means has been made making it possible to stabilize the adjustment of the orientation of the fastener on the module on the one hand, and a fixing adjustable in length and removable. .

In Figures 6a to 6c, there is shown a right view, a front view and a left view of a capsule 81. The end 90 of the elastic cord 80 is inserted into the box 85 passing through a baffle 89, 91, 92 here constituted by three ribs forming angles

REPLACEMENT E around the central hole 91 for passage of the fixing and adjusting screw. The box 85 has a through hole on its periphery which allows the cord 80 to exit the capsule. The external face of the box, intended to come opposite the orientable adjustment module already described carries the notched sector 87. Finally, the fastener shown in Figures 1 (fastener 11) and in Figures 5 and 6a to 6c, also includes a cranial support piece intended to be placed behind the skull of the user and which is made of a shock absorbing material pierced with two holes 95 and 96 for passage of the cord 90. So far, an embodiment has been described of the adjustable adjustment module according to which the adjustment and orientation of the fastener relative to the module are obtained by tightening a screw in one of the suitable threaded holes in the module. In particular, the wash like the screw 83 of Figure 5 may include a means to make its constant tightening despite the activities of. the user. Such a means is, in a preferred embodiment constituted by a lug on the junction between the threaded rod 84 and the head 83 of the screw so as to be housed in a clips made on a fixed part such as the edge of the casing 85 or a part not shown of the housing 85 which surrounds the hole 91 for the passage of the screw 84. The clip then blocks the screw in rotation except when exerting a force allowing the abovementioned lug to come out of its clips.

In the following Figures, another embodiment of a swiveling adjustment module according to the invention has been shown. One of the advantages of this embodiment is that it makes it possible to reduce the lateral bulk caused by the screw of the mode described above, and also to allow adjustment and / or orientation of the fasteners without removing the glasses. Such an operation is desired

LOCATION SHEET for example when the user wears the glasses under a ski or motorcycle helmet and needs to lift the glasses for a moment.

In Figures 7a to 7c, there is shown glasses incorporating such an embodiment of modules according to the invention. The frame 100 carries a single lens 101 constituting a window for example for its use on a motorcycle under a protective helmet. It is then necessary to reduce the thickness of the parts of the glasses which are between the helmet and the head of the user.

To this end, the fastener, which here consists of a branch 103, carries a pull bar 104 notched on its upper and lower parts, so as to facilitate its handling, and mounted on elastic means which will be described later. These elastic means make it possible to move the puller towards or away from the orientation adjustment module 102 placed between the frame 100 and the branch 103.

As seen in Figures 8a and 8b, which are detailed views of the branch 103 shown disassembled glasses, we note that the pull tab 104 has been brought closer to the pin 111 of articulation of the branch on the adjustment module 102.

In addition, the pull tab 104 carries on its vertical flank a sector 113, with a function similar to that of the notches 53 of FIG. 6. But the notched sector 113 works axially and cooperates with a notched sector 107 represented in FIG. 7c and carried by the swiveling adjustment module 102.

The elastic means consist of a spring 114, the right end of Figures 8a and 8b is linked to the branch 103 on a housing 115 thereof. The left end of Figures 8a and 8b is linked to the pull tab which slides on the front part 110 of the branch 103. The spring 114 is of flat shape according to the representation in

REPLACEMENT SHEET drawing. In another embodiment, the spring 114 is of cylindrical shape or can also be constituted by a bimetal spring.

In Figure 8a, the pull tab 104 is shown in the open position. In FIG. 7c, the movements (I), (II), (III) and (IV) are shown which it is then possible to give to the branch 103. In fact the latter is articulated by the pin 111 on holes 105 or 106 made on the adjustment module 102. In this way, it is possible to adjust the orientation of the fasteners 103 relative to a reference direction of the glasses. In Figure 9, there is shown a schematic detail explaining the configuration of the adjustment means of the orientation adjustment module in this other embodiment according to the invention. The fastener 120 comprises a pin 128 of elliptical or other cut. The general direction 123 of the clip 120 is aligned with the reference direction 127 linked to the orientation adjustment module of the invention.

The pin 128 is housed in a circular hole 125, the center of which passes through the coincident axes 123 and 127 and which is formed on the rigid plastic plate constituting the adjustment module. The hole 125 has a vertical axis 121.

The latter has not been shown so as not to load the drawing and in addition, the hole 125 is shown in dotted lines. The module also comprises at least one other hole 126, the center of which is the intersection of the axis 124 parallel to the reference direction of the module for adjusting the orientation and of a perpendicular axis 122.

The distances between the pairs of parallel axes mentioned above, respectively 121 and 122 on the one hand, and 127 and 124 on the other hand, are such that the two holes communicate with each other by a communication space. In Figures 10a to 10c, the sequence of

LOCATION SHEET movements making it possible to adjust the length of the fastener 120 away from the axis 121. For this, the pin 128 is passed from hole 125 to hole 126.

In FIG. 10a, the attachment 120 is noted along the section 129. As a result, the pin 128 is linked to the attachment 120 is present in the communication space of the hole 125 in the hole 126. The minor axis of the elliptical section of the pin 128 is chosen so as to allow it to pass through this space.

In Figure 10b, the fastener is lowered by a force represented along the arrow 130 and the pin descends into the hole 126. In Figure 10c, the fastener 120 is shown again aligned 123 on the reference direction of the orientation adjustment module, here along the axis 124 (and no longer 127). It can be seen that the center of the pin has moved back on the axis 122. The distance between the rear of the clip and the center of the hole 125 has therefore been increased by the distance between the two axes 121 and 122.

There is thus a simple means for adjusting the length of the fastener relative to the module for adjusting the orientation. In Figure 11, there is shown an adjustment in a hole, here 126 of the relative orientation of the clip 120 and the orientation adjustment module relative to the reference direction of the latter.

By moving back the pull tab 104 described in the preceding figures, the notches 107 of the module are released from those notches 113 of the pull tab. It then suffices to exert a rotational force along the arrow 131 to ensure adjustment of the orientation of the axis 123 of the fastener relative to the reference direction of the module. To avoid losing the length adjustment, just do not exceed the angle made between this reference direction and the right joining the centers of two holes

REPLACEMENT SOCKET 125 and 126 in communication on the module. It is noted that therefore the notched sectors 113 and 107 must be of half-angle at least equal to this aforementioned angle so as to keep the angular adjustment stable. In Figures 12 to 14, there are shown three views including a section along the axis AA (Figure 13) of a module 150 for adjusting the orientation according to this embodiment of the invention.

The module 150 is produced by a plate of rigid plastic material pierced with a series of holes with vertical axes a, b, c and d aligned on axes 156 and 157 parallel to the reference direction of the module (the line cutting AA). The holes a, b, c, d have the function described in Figures 9 to 11.

A first edge of the module 150 is lined with a notched sector 151 formed by teeth 152 in the general plane of the module. These teeth cooperate with the notched sector of the pull tab mounted on the aforementioned fastener to make stable the adjustment of the relative orientation of! and module.

A second edge of the module 150 carries a removable fixing means such as a hinge 153 which is inserted on a reciprocal fixing member of the frame or directly of the optical element of the glasses.

It is clear that the shapes of the holes 125 and of the pin 128 of the fastener can be modified according to the teachings of the invention. Likewise, their number and arrangement in more than two levels can be selected according to technical circumstances.

The notched upper and lower zones of the pull tab 104 are intended to allow easy manipulation by the user. It is clear that other means can be added, in particular because the adjustment both of the length and of the orientation can be carried out by the user by manipulating the frame without removing the glasses or when the pull tab 104 is inaccessible (case

LOCATION SHEET where the glasses are worn under a helmet and where the clip is therefore inaccessible). Similarly, it is possible to practice an accessory housing as the description in Figure 3b.

The description of the invention relates essentially to glasses proper. It should be recalled that the invention is also applicable to a mask which comprises a single optical block, also called optical strip or optical element or even screen.
