DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

In the following description, the same numerical references refer to similar elements. The embodiments shown in the figures are preferred, and are namely used for exemplification purposes only.

The present invention was primarily designed as a protective face mask 1 for sports such as paintball; it also has other applications such as military and the like. Thus, the following description should not be construed as limiting only to the enumerated applications, and should be considered on a broader spectrum.

Referring now to drawings, FIG. 1 illustrates mask 1 according to a preferred embodiment of the present invention. As seen on FIG. 2, mask 1 comprises a substantially rigid support frame 7 and a complementary mouth and ear portion 9 that is substantially flexible, and which is either glued on or overmolded onto the substantially rigid support frame 7 via a suitable manufacturing process. The substantially rigid support frame 7 is generally provided for protecting the user and for mounting different components of the face mask, while the more substantially flexible mouth and ear complementary portion 9 protects the mouth and the ear regions of the user.

The substantially rigid support frame 7 is operatively rested against the face of a user, and is appropriately fastened on user's face via a corresponding fastening strap 11, as seen on FIGS. 2 and 9. Moreover, as can be easily understood when referring to FIGS. 2, 9 and FIGS. 17-23, a lens 3 is preferably provided, and is preferably removably mountable onto the substantially rigid frame 7. According to the preferred embodiment of the present invention, lens 3 is transparent to enable a user to properly see through it, and is made of a suitable material such as polycarbonate or other strong materials known in the art.

Lens 3 and frame 7 should be preferably designed so as to comply with ASTM and other norms required in the industry in terms of impact and the like, as required by the given sport for which the protective face mask is intended for. Indeed, generally, a series of tests are carried out on the protective face mask, and the latter is preferably designed so as to ensure a proper retention of the lens, without the penetration of paint from the paintballs, or any other projectile in other applications such as military applications, in the region of the eyes of the wearer as well as other sensitive regions of the wearer's head. The protective face mask according to the present invention should also be designed so as to properly withstand different ranges of temperatures.

As can be also easily understood when referring to FIGS. 2 and 9, the protective face mask according to the present invention is preferably shaped and sized so as to properly cover and shield the face of a given user, namely in the region of the eyes, such as the eyes, the eyebrows, the cheekbones, and other adjacent regions, such as the ears, the temples, and other regions of the face or of the head of the user which may be subject to the impact of paintballs and the like or the penetration of other projectiles in other applications.

As better shown in FIGS. 2 and 9, as well as in FIGS. 26-35, the protective face mask preferably comprises a face engaging element or foam support 5, provided with a corresponding face engaging portion or foam 13, which preferably acts as a cushion between the face of the given user and the substantially rigid support frame 7 of the face mask, and also preferably comprises, as aforementioned, a substantially elastic fastening strap 11 so as to properly and adequately retain the protective face mask in place about the face and/or head of the corresponding user.

Lens 3 is preferably locked into place with a pair of lens lock clips 15. These lens lock clips 15, provided on preferably the left and right sides of the protective face mask 1, respectively lock the lens 3 into place onto the substantially rigid support frame 7. Substantially rigid support frame 7 of the mask is preferably made of nylon or any other suitable material known in the art for its characteristics, and mouth and ear portion 9 is preferably made of Santoprene™ and other material known in the art for elastic characteristics.

An important aspect of the present invention is that the protective face mask also comprises a face engaging element or foam support 5 which is removably mountable onto the protective face mask, preferably onto the substantially rigid support frame 7. Foam support 5 is removably connectable and kept in place on the frame 7 to act as an interface between the mask (and more particularly, the frame thereof) and the face of a user.

Removable and detachable foam support 5 preferably comprises rims 17 shaped and sized so as to be received into corresponding complementary recesses 20 provided along an inner portion of the substantially rigid support frame 7 (FIG. 5). Face engaging element 5 is provided with an engagement means such as orifices 19 to be introduced into corresponding engagement means formed in the support frame 7, such as alignment pins 21 (FIG. 5) projecting from said inner portion of said support frame 7. Face engagement element 5 is provided with face engagement locking means comprising side tabs 23 provided with corresponding holes 25 intended to cooperate with corresponding side holes 27 of the support frame 7 and intended to be securely affixed thereto via corresponding lock buttons 29, so as to securely maintain the foam support 5 in place when it has been properly positioned about the protective face mask, and more particularly the substantially rigid support frame 7. As can be easily understood by a person skilled in the art when referring to the accompanying drawings, and more particularly FIGS. 2 and 9, as well as FIGS. 26-35, once the lock buttons 29 have been used to properly secure the foam support 5 about the mask frame, a pair of lens lock clips 15 are clipped onto the mask, one on each side of said mask 1, so as to properly cover access to said lock buttons 29, and securely maintain the lens 3 in place, as a result of the lens lock clips 15 being shaped and sized so as to cover not only the lock buttons 29, but also cooperate with a corresponding extremity 31 of the lens 3 projecting from a side bar 33 of the mask when appropriately mounted onto the substantially rigid support frame 7, as better shown in FIGS. 2 and 9, as well as in FIGS. 17-23.

According to the preferred embodiment of the present invention, the lens lock clips 15 (FIGS. 2c,d) are provided with corresponding protrusions 35 intended to be inserted through corresponding side slits 37 of the protective face mask, so as to protrude from an inner portion of said mask, and so as to receive corresponding strap clips 39 located on both ends of the fastening strap 11. Protrusions 35 of the lens lock clips 15 comprise female recesses 35a intended to receive corresponding male protrusions 39a extending from the strap clips 39. As can be easily understood by a person skilled in the art when referring to the accompanying drawings and the present description, the design of such lens lock clips 15 and their interaction with the other components of the protective face mask are intended so that a user first requires to properly install and secure the foam support 5 and/or lens 3 onto the support frame 7 before being able to properly connect the strap 11 onto the mask and mounting said mask 1 onto the corresponding user, which is particularly advantageous, in that the mask is intended to ensure that the proper safety features are in place before enabling the user to use said mask. Indeed, for example, if the lock clips 15 are not properly mounted onto the protective face mask, then a user would not be able to clip the corresponding fastening straps clips 39 into said lock clips 15, and to be able to use the protective face mask with corresponding fastening strap.

Furthermore, the provision of such lens lock clips 15 is also particularly advantageous in that they are preferably intended so as to prevent the lens from being dislodged during impact of paintballs and the like.

As previously mentioned, a main function of the lens lock clips 15 is to retain the lens 3 onto the protective face mask, in the preferred manner described above, but also to retain and ensure that the lens 3 remains in place during the impact, or the repeated impacts of paintballs and the like. Without the lens lock clips 15 mounted onto the protective face mask (as seen on FIGS. 17-35), the fastening strap 11 cannot be removably connected onto the protective face mask, and the user would not be able to use the protective face mask. This procedure ensures that the user has undertaken certain preliminary safety measures regarding the mask before using it.

In addition to the above-mentioned foam support 5, the protective face mask according to the present invention comprises temple foam supports 41, as better shown in FIGS. 2, 2a-2e, which are preferably intended so as to ensure also a greater comfort and stability of the mask. More particularly, the protective face mask preferably comprises a pair of temple foam supports 41 (FIGS. 3a-3e), one on each side of mask 1. Temple foam supports 41 are preferably removably mounted onto the mask 1, and more particularly onto a rear extremity of the mouth and ear complementary assembly 9. Each temple foam support 41 comprises a pair of pins 42 projecting from a rear portion thereof, said pair of pins 42 as seen on FIGS. 3a to 3e being removably insertable and clipped into corresponding holes 44 provided along a rear portion of the mouth and ear protective overmolded assembly 9, as can be easily understood when referring to FIGS. 2 and 9. Foam 40 is glued to the face-engaging surface of temple foam supports 41. Other attachment methods of temple foam supports 41 are available to the skilled in the art.

Different suitable materials or foams known in the art can be used for the foam 13 of the foam support 5, and/or on the temple foam supports 41. Preferably, foam 13 and foam of temple support 41 is attached by gluing.

According to another preferred embodiment of the present invention, and as better illustrated in FIGS. 10, 10a and 10b, the protective face mask may be provided with a corresponding visor 43, which is preferably mechanically attached to the foam support 5 by means of protrusions 42 extending from inner surface of visor 43. Said protrusions 42 are adapted to be locked into corresponding slots 47 formed in the face engagement element 5. Visor 43 is not only functional, in that it is intended to protect or shade the eyes of the mask user from sunlight and the like, but also provides the mask with a certain aesthetic style. Furthermore, the provision of such visor 43 can also be intended to protect the lens 3: if the mask is dropped incorrectly onto a surface, visor 43 is shaped in such a way that it will deflect any deleterious blow to lens 3, and is thus intended to protect the lens against scratching and other undesirable effects.

The material used for the frame 45 of the foam support 5 is preferably nylon, or any other suitable material, so as to provide for a substantially rigid frame 45 of the foam support. Visor 43 is preferably made of a more flexible material such as a thermoplastic elastomer or Santoprene™, but may be made of other suitable materials.

An important advantage resulting from the present invention resides in that the foam support 5 is a separate piece that is removably mountable onto the protective face mask, and more particularly the support frame 7. It can be easily interchanged not only to replace foam 13 for either wear or hygienic reasons, but to customize mask 1 for any characteristic trait of a person's face. For example, the same mask 1 can be used during the transition from child to adult by simply swapping foam support 5 from a smaller to a larger size. Removable foam support 5 is advantageous for a same user during one day of use: if one foam support 5 becomes moist due to excessive perspiration, the user may easily replace a wet foam support 5 with a dry foam support 5, thereby resulting in a more enjoyable day of sports.

The foam support 5 and lens 3 according to the present invention are preferably designed so as to be removably mountable and fastened/clipped onto the mask in a “user friendly” manner so as to enable for an easier part replacement without the need of tools except a coin (see FIGS. 17-35).

FIGS. 17-20 illustrate partial schematic representations of a removal of a lens from a protective face mask according to a preferred embodiment of the present invention, wherein FIG. 17 illustrates the declipping of the strap, FIG. 18 illustrates the removal of the lock clip 15, FIG. 19 illustrates the removal of one side at a time of the lens 3, and FIG. 20 illustrates the pushing of the lens 3 out of the frame.

FIGS. 21-23 are partial schematic representations of the installation of the lens onto the protective face mask according to a preferred embodiment of the present invention, wherein FIG. 21 illustrates the insertion of the lens 3 onto the mask, FIG. 22 illustrates the insertion of the lock clip 15 back into place, a portion of the lock clip 15 being inserted behind an extremity 31 of the lens 3 so as to fasten and abut said extremity against the sidebar 33 of the support frame 7, and FIG. 23 illustrates the clipping of the strap 11 back into a corresponding protrusion 35a of the corresponding lock clip 15.

FIGS. 24 and 25 are schematic representations of the installation of a visor 43 onto the protective face mask according to a preferred embodiment of the present invention, wherein FIG. 24 illustrates the insertion of the visor, and more particularly the insertion of corresponding protrusions 42 of said visor 43 into corresponding slots 47 of the foam support 5, and FIG. 25 illustrates the insertion of corresponding o-rings 28 so as to property attach and secure the visor 43 to said foam support 5, as can be easily understood by a person skilled in the art.

FIGS. 26-30 are partial schematic representations of a removal of a foam support 5 onto a protective face mask according to a preferred embodiment of the present invention, wherein FIG. 26 illustrates the declipping of the strap 11, FIG. 27 illustrates the removal of the lock clip 15, FIG. 28 illustrates the turning of the lock button 29 clockwise into the “unlocked” position, FIG. 29 illustrates the pulling of the foam support 5 on one side at a time from the support frame 7 of the mask, and FIG. 30 illustrates the removing of the foam 5 support from the frame 7.

FIGS. 31-35 are partial schematic representations of the installation of a foam support 5 onto a protective face mask according to a preferred embodiment of the present invention, wherein FIG. 31 illustrates the insertion of the foam support 5 into the preferred corresponding four pins 21 projecting from an inner portion of the substantially rigid support frame 7 of the mask, FIGS. 32 illustrates putting the foam support 5 back onto the support frame 7, one side at a time, FIG. 33 illustrates turning the lock button 29 counterclockwise into the “locked position”, FIG. 34 illustrates the removing of the lock clip 15, and FIG. 35 illustrates the declipping of the strap 11.

Thus, in view of the above, it can be easily understood that the installation or removable of the foam support 5, and other components of the protective face mask, such as the lens 3, the visor 43, and the like, are easily carried out in a “user friendly” manner, without the use of specialized tools. For example, a user only requires to remove the strap 11 to be able to remove the corresponding lock clip 15, and thus operate the corresponding lock buttons 29 to properly remove the foam support 5 from the substantially rigid support frame 7 of the mask 1. The operation of the lock buttons 29, namely the operation between the corresponding locked and unlocked positions, can be carried out via a coin-shaped element (not shown) shaped to be insertable into a corresponding recess of the lock button 29. Preferably, the lock buttons 29 are designed so that each one of them be turned in a proper direction, along one quarter of a turn preferably, between corresponding demonstrative icons (see FIG. 28) representing the “unlocked” and “locked” positions.

Foam support 5 can be modified with casings or housings that would enable greater or improved ventilation or that can receive electronics to enable a system of communication with other protective face masks 1. Other applications for foam support 5 are possible as conceived by the skilled in the art.

As better shown in FIGS. 2 and 9, the foam support 5 is preferably provided with a corresponding frame 45 being shaped and sized accordingly to somewhat distance the face and eyes of a given user from the support frame 7 of the mask. Corresponding slots 47 on upper and lower portions of said support frame 45 of the foam support 5 enable improved air circulation between the face of the user and the lens to prevent condensation on the lens, and provide for more comfort. Upper slots 47 of the corresponding frame 45 of the foam support 5 are also intended to receive the projecting fastening pins 42 of a visor 43 according to a preferred embodiment of the present invention, seen on FIGS. 9-16, and the installation of said visor 43 as seen on FIGS. 24 and 25.

Considering that the material used for frame 45 of the foam support 5 is substantially rigid, frame 45 of said foam support 5 is preferably provided with a series of longitudinal slits 48 (FIG. 2a) on an inner portion thereof to provide the foam 5 support with a certain curvature flexibility.

Overmolded complementary mouth and ear portion 9 of the protective face mask is preferably provided with corresponding orifices and grilled portions so as to enable a proper breathing and/or hearing capability to the user of the mask, and preferably comprises distinguishing features so as to provide the mask with a corresponding esthetic profile. For example, the overmolded complementary portion of the mask preferably comprises a pair of rearwardly projecting horns 49 on the front mouth portion of the mask, and also preferably comprises corresponding upper intrusions 51 in the upper portion of the mask so as to be representative of “eyebrows”, or other like features. Preferably also, the color of the material of the substantially rigid support frame 7 of the mask and that of the overmolded complementary portion 9 are different so as to create a visual contrast between the support frame and the corresponding overmolded portion. Thus, it can be easily understood by a person skilled in the art that one may use the technology of overmolding so as to provide the present protective face mask with corresponding overmolded complementary portions which would provide the mask with distinguishable esthetic features, so as to give a particular look to the mask, or to a corresponding family of masks, of a given manufacturer (distributor, wholesaler, etc.) of masks according to the present invention.

Finally, and according to the present invention, the mask and corresponding parts are preferably made of substantially rigid materials, such as hardened polymers, composite materials, and/or the like, whereas other components thereof according to the present invention, in order to achieve the resulting advantages briefly discussed herein, are preferably made of a suitably malleable and resilient material, such as a polymeric material (plastic, etc.), and/or the like, depending on the particular applications for which the mask is intended for and the different parameters in cause, as apparent to a person skilled in the art.

Furthermore, the present invention is a substantial improvement over the prior art in that, by virtue of its design and components, the mask 1 and corresponding parts are simple and easy to use, as well as are simple and easy to manufacture and/or assemble, without compromising the reliability of its functions.
