Description
- The present invention relates to an attachment assembly for mounting a facemask to a sports helmet in such a way that the facemask will absorb and/or dissipate a very high percentage of impact energy from a ball or other oncoming force.
- Helmets are used in a wide range of sports. Helmets generally serve the same purpose in each sport, which is to protect the wearer's head from injury by providing a buffer zone between the wearer's head and an oncoming ball, puck, club, or other moving object.
- Helmets worn by umpires and catchers in baseball or softball, football players, hockey players, and lacrosse players are well known and typically include a shell having inner and outer surfaces and a padding assembly connected to the inner surface of the shell. Many sport helmets also typically include corresponding facemasks mounted to the helmet. However, conventional facemask mountings provide little, if any, shock absorption. More particularly, when a moving object strikes the facemask, the force is typically transferred directly to the helmet with very little buffering or dampening. The current design of catcher's helmets, for example, transfers a very high percentage of impact energy from the ball directly to the wearer's head. This problem is also present in umpire masks and other helmets that include facemasks.
US 5,956,777 discloses a shock-absorbing facemask assembly for attachment to a sports helmet comprising a facemask and a spring assembly which acts as a shock absorber. - It would be desirable to provide a facemask that is mounted to a helmet such that the facemask can absorb and/or dissipate an increased percentage of impact energy from an oncoming ball, puck, club, or other moving object.
- The object of the present invention is to provide a shock-absorbing facemask attachment assembly for attachment to a sports helmet that provides absorption and dissipation of a high percentage of impact energy from an oncoming object. This shock absorption and dissipation is achieved through an assembly according to claim 1, allowing the facemask to greatly increase the impact absorption and to distribute a large amount of impact energy. The dependent claims are directed to advantageous developments of the invention.
- According to the invention, the shock-absorbing facemask attachment assembly includes a spring assembly in which a first spring has a first end coupled to a helmet and a second end coupled to a housing, and a second spring has a first end coupled to a facemask and a second end coupled to the housing. A third spring may also have a first end coupled to the facemask and a second end coupled to the housing. The springs may be substantially perpendicular to a helmet shell. Any or all of the springs may be coupled to the helmet shell, housing, or facemask with one or more fasteners. Any of the fasteners may include nylon for enhanced flexibility.
- Any of the facemask mounting assemblies described herein may be attached to opposing sides of the helmet shell along opposite edges of a face opening portion of the helmet. In certain embodiments, one or more of the mounting assemblies may be attached to each side of the helmet shell. Alternatively or additionally, one or more of the mounting assemblies may be attached to the helmet shell in a central region above a face opening in the helmet. To highlight the shock-absorbing mechanism of the facemask attachment assembly, the housing and/or any cover portion may be transparent.
- Any of the shock-absorbing facemask attachment assembly embodiments described herein may be applied to catcher's masks, umpire's masks, lacrosse helmets, football helmets, hockey helmets, and any other helmet that includes a facemask.
Regardless of the type of helmet, shock-absorption is greatly improved by using any of the mounting schemes in this invention. -

FIGURE 15 is a side view of a helmet having a shock-absorbing facemask attachment assembly in accordance with an embodiment, not forming part of the invention. - Referring to
FIGS. 1 and 2 , a helmet having a shock-absorbing facemask attachment assembly is indicated generally at 20. Thehelmet 20 ofFIG. 1 is configured as a catcher's helmet; however, the invention can also be applied to other types of helmets, such as, for example, an umpire's helmet and/or mask, a lacrosse helmet, a football helmet, a hockey helmet, and practically any other type of helmet that includes a facemask. The helmet includes ashell 22, a padding assembly (or head support assembly) (not shown), and afacemask 24. - The
shell 22 is a generally hemispherically-shaped head covering, which forms acranial cavity 26 configured to generally cover and protect the upper portion of a user's head. Theshell 22 has a dome-like crown 28, a generally continuouscircumferential side wall 30, first and second earprotective regions protective region 36 that surrounds a wearer's neck. Preferably, thecrown 28,side wall 30, first and second earprotective regions protective region 36 are integrally formed to one another. Alternatively one or more of theseshell 22 regions can be connected together in a non-integral manner. Other types of helmets may differ in terms of the shell configuration. For example, football helmets may not include the neckprotective region 36. - The
shell 22 is formed of a rigid, durable material, preferably, acrylonitrile-butadiene-styrene ("ABS"). Alternatively, theshell 22 can be formed of other materials, such as, for example, a polycarbonate, plastic, aluminum, or other polymers. One example of a commercially-available material having considerable durability is Surlyn® produced by E.I. du Pont de Nemours and Company, 1007 Market St. Wilmington, Delaware 19898 ("DuPont"). Theshell 22 is configured to protect the user's head by resisting, absorbing and distributing impact loads, such as, for example, the impact from a pitched ball, thereby reducing the load transferred to or felt by the user due to an impact. The padding assembly (not shown) is coupled to an inner surface of theshell 22 and may include a plurality of support members configured to dampen, reduce, absorb, and/or dissipate shock resulting from an impact of the helmet with an object, and reduce the shock transferred to, or felt by, the wearer due to an impact. The padding assembly can be formed of a lightweight, cushionable, resilient material, such as a foam material formed of ethyl vinyl acetate ("EVA foam"), or other open or closed cellular or non-cellular foam, a gel, a fluid-filled bladder, a plurality of spherical balls, a plurality of other geometric objects, or an air-filled bladder. - Referring to
FIG. 2 , the facemask 24 includes a plurality of generally vertical andhorizontal bars 38 fitted over a face opening 40 in thehelmet 20 and configured to protect a wearer's face without adversely obstructing the wearer's vision or ability to breathe. Two ormore attachment assemblies 42 anchor the facemask 24 to theshell 22. Thebars 38 of thefacemask 24 are made of a rigid material, such as, for example, ABS, other high-density polymers, such as Surlyn®, aluminum, compo site fiber materials, and combinations thereof. The number, size, shape, and placement of thebars 38 may vary among different embodiments, as theattachment assemblies 42 described herein are adaptable for use with a wide range of facemask 24 configurations. For example, the bars can be formed in other shapes, such as curved shapes, angled shapes, and combinations thereof. Alternatively the facemask may be formed of structures other than bars. For example, the facemask can be a one piece molded structure configured to match the size of the face opening of the helmet. -
FIG. 3 illustrates a force (F) acting upon thefacemask 24. The attachment assemblies 42 (or energy dissipation assemblies) in combination with thefacemask 24 provide absorption and dissipation of a high percentage of impact energy from an oncoming object hitting the facemask, thereby transferring less impact energy to theshell 22. Theattachment assemblies 42 serve as a form of a biasing assembly. Thefacemask 24 is susceptible to being hit from all angles. Consequently, the impact forces are often in directions other than straight back. Although the force (F) illustrated herein is representative of force from an oncoming object, theattachment assemblies 42 described herein are designed to absorb and dissipate energy from multiple directions. - A cross section of the
attachment assembly 42 inFIG. 2 is illustrated inFIG. 4 . Thesame attachment assembly 42 is illustrated inFIG. 5 , showing the effects of the force (F) inFIG. 3 acting upon theattachment assembly 42. In this embodiment, theattachment assembly 42 includes ahousing 44 attached to theshell 22 of thehelmet 20. Arigid insert 46 includes afirst end 48 coupled to thefacemask 24 and asecond end 50 disposed in thehousing 44. Therigid insert 46 is adapted to extend thesecond end 50 further into thehousing 44 in response to a force (F) applied to thefirst end 48.FIG. 6 is a composite view of another embodiment not forming part of the present invention showing the displacement of therigid insert 46 within thehousing 44 in response to the force (F). - Alternatively the displacement of the
rigid insert 46 within thehousing 44 is modeled after a hydraulic piston. For enhanced shock-absorption and energy dissipation, a resilient, compressible cellular material, such as a foam, a resilient sponge-like material, a compressible fluid or agel 52 may be present within thehousing 44 between adistal surface 51 of thesecond end 50 of therigid insert 46 and abottom surface 54 of thehousing 44, as shown inFIG. 7 . - For enhanced shock-absorption of impact forces and dissipation of energy from various directions, at least a portion of the
housing 44 may include a durable, resilient material, such as an elastomer. Additionally or alternatively, at least a portion of therigid insert 46 may include an elastomer. Examples of suitable elastomers include, but are not limited to, Neoprene polychloroprene, available from DuPont, as well as Lexan® EX L polycarbonate resin, available from GE Plastics, One Plastics Ave., Pittsfield, MA 01201 ("GE Plastics"). Not only is Lexan® EXL impact-modified and capable of providing improved flow and notch sensitivity, this resin is also transparent. In certain embodiments, at least a portion of thehousing 44 may be transparent, translucent, semi-transparent or semi-translucent, thus allowing a consumer to view the shock-absorbing system. Other materials suitable for inclusion in theattachment assembly 42 include Surlyn®, for example. Still further, theinsert 46 may be formed of a semi-rigid or generally rigid material. Theinsert 46 andhousing 44 can be configured to enable the insert to change positions within the housing in response to an impact. Alternatively, one or more of the insert and housing can be configured of shock absorbing material to allow for the absorption and dissipation of impact energy with limited relative movement of the insert with respect to the housing. In such an embodiment, the properties of the materials serve to absorb or dissipate energy from an impact. - The
helmet 20 may include at least one of theattachment assemblies 42 on each side of theshell 22 along opposite edges of theface opening portion 40 of thehelmet 20. As illustrated inFIG. 3 , for example, thehelmet 20 may include at least four of theattachment assemblies 42, with at least two of theattachment assemblies 42 positioned on each side of theshell 22 along opposite edges of theface opening 40 in thehelmet 20. Additionally, one or more of theattachment assemblies 42 may be mounted to theshell 22 in a central region above theface opening 40 in thehelmet 20 or in other locations about theshell 22 including above or below thefacemask 24. Overall, thefacemask 24 may be mounted to theshell 22 using at least threeattachment assemblies 42, and may include as many as about tenattachment assemblies 42. One or more of theattachment assemblies 42 may be a conventional attachment assembly known to those skilled in the art, such as a conventional leaf spring system, as illustrated inFIG. 13 . - Another
attachment assembly 42 is illustrated inFIG. 8 . This type ofattachment assembly 42 includes a spring or biasing system. More particularly, thisattachment assembly 42 includes ahousing 56 attached to theshell 22, with at least onespring 58 having afirst end 60 coupled to thefacemask 24 and asecond end 62 disposed in thehousing 56. The at least onespring 58 is adapted to be compressed further toward thehousing 56 in response to a force (F) applied to thefirst end 60. In certain embodiments, two ormore springs 58 may be included in eachattachment assembly 42. Whenmultiple springs 58 are present in anattachment assembly 42, thesprings 58 are suitably substantially parallel to one another. For example, theattachment assembly 42 inFIG. 8 includes threesprings 58 coupled to thefacemask 24 and thehousing 56, with thesprings 58 substantially parallel to one another. Additionally, thebar 38 of thefacemask 24 to which the first ends 60 of thesprings 58 are attached is suitably perpendicular to thesprings 58. Alternatively, the springs can be angled with respect to each other to further enhance the ability of the helmet to absorb or otherwise dissipate energy resulting from impacts with an object such as a ball in multiple directions. -
FIG. 9 is a cross-sectional view of anindividual spring 58 taken along line 9-9 inFIG. 8 . As shown, thefirst end 60 of thespring 58 may be coupled to thefacemask 24 with afirst screw 64 and thesecond end 62 of thespring 58 may be coupled to thehousing 56 with asecond screw 66. Alternatively, the springs or biasing members can be coupled to the facemask or the housing using other types of conventional fasteners, such as, for example, rivets, snap-fit joints, etc. A resilient compressibleintermediate member 68, such as an elastomer, may or may not be positioned within thespring 58 between thefirst screw 64 and thesecond screw 66. One or both of thescrews - The
attachment assembly 42 may also include acover 70 over the portion of thefacemask 24 coupled to thefirst end 60 of the spring or springs 58, as shown inFIG. 8 . Thiscover 70 may serve as a strike or shatter device to prevent damage to the underlying connection. Additionally, thecover 70 may enhance the aesthetic appeal of thehelmet 20. Thecover 70 and/or thehousing 56 may be transparent, translucent, semi-transparent, or semi-translucent. Thecover 70 may also be used to assist in securing thesprings 58 to thefacemask 24. For example, afirst bar 38a of thefacemask 24 may be coupled to thefirst end 60 of thesprings 58 and a second bar 38b of thefacemask 24 may be coupled to thecover 70. -
FIG. 10 provides an exploded view of anattachment assembly 42. Theattachment assembly 42 is a spring or biasing system that includes thehousing 56 attached to theshell 22 of the helmet, adampener 58, acover 74, asleeve 68 and arigid insert 72. Therigid insert 72 can be welded or otherwise fixedly or removably secured to thefacemask 24. Theinsert 72 extends through thesleeve 68 and thecover 74 and into thedampener 58. Thesleeve 68 surrounds a portion of theinsert 74 and is typically formed of a resilient material, such as, for example, a plastic or an elastomer. Thesleeve 68 is positioned adjacent to, but preferably does not extend into, thecover 74. Thesleeve 68 maybe colored or may include a decorative pattern. Thecover 74 surrounds thedampener 58 and extends into thehousing 56. Thecover 74 protects thedampener 58 from binding or otherwise engaging the sleeve or theinner surfaces housing 56. Thedampener 58 is a resilient biasing member that is configured to absorb and/or dissipate energy applied to thefacemask 24 and theinsert 72 from an impact. - A preferred embodiment of the
attachment assembly 42 in accordance with the invention is illustrated inFIGS. 11 and12 . This type ofattachment assembly 42 also includes a spring or biasing system. More particularly, thisattachment assembly 42 includes afirst spring 76 having afirst end 78 coupled to theshell 22 and asecond end 80 coupled to ahousing 82, and asecond spring 84 having afirst end 86 coupled to thefacemask 24 and asecond end 88 coupled to thehousing 82. As shown inFIG. 11 , athird spring 90 may also have a first end coupled to thefacemask 24 and a second end coupled to thehousing 82. Thesprings shell 22 at which they are attached. - As in previous embodiments including spring assemblies, screws may be used to fasten the
springs attachment assembly 42. Alternatively, other conventional fasteners can also be used. More particularly, thefirst end 78 of thefirst spring 76 may be coupled to theshell 22 with afirst screw 92 and thesecond end 80 of thefirst spring 76 may be coupled to thehousing 82 with asecond screw 94. Additionally, thefirst end 86 of thesecond spring 84 may be coupled to thefacemask 24 with athird screw 96 and thesecond end 88 of thesecond spring 84 may be coupled to thehousing 82 with afourth screw 98. Thethird spring 90 may be attached to thefacemask 24 and thehousing 82 in the same manner as thesecond spring 84. Any of thescrews - As shown in
FIG. 12 , the force (F) from an oncoming object hitting thefacemask 24 acts on theattachment assembly 42 in a direction perpendicular to thesprings housing 82 may be transparent to allow a consumer to view the shock-absorbing system. - Conventional attachment assemblies may also be modified to provide a greater shock-absorbing mechanism for attaching a
facemask 24 to ashell 22. For example, the leaf spring attachment assembly inFIG. 13 appears to be a conventional leaf spring assembly. However, theleaf spring 100 itself and/or thescrew 102 securing theleaf spring 100 to theshell 22 may include an elastomeric material to enhance the energy absorption of theattachment assembly 42. Suitable elastomeric materials are described above. - The
attachment assembly 42 may include thehousing 44 positioned on thefacemask 24 and therigid insert 46 mounted to theshell 22, as shown inFIG. 14. FIG. 14 shows two of a total of fourattachment assemblies 42. Thehousing 44 and theinsert 46 are substantially similar to the earlier described embodiments, other than thehousing 44 is mounted to thefacemask 24 rather than theshell 22 and theinsert 46 is mounted to theshell 22. Other quantities of attachment assemblies are also contemplated. - In
FIG. 15 , the shock absorbingattachment assembly 42 may be wholly incorporated within thefacemask 24, such that thehousing 44 is mounted to one ormore bars 38 of thefacemask 24 and therigid insert 46 is mounted toother bars 38 of thefacemask 24. One ormore attachment assemblies 42 may be incorporated within thefacemask 24, and may be mounted to one or more bars 38. Thefacemask 24 may be mounted to theshell 22 using either conventional attachment assemblies or any of theattachment assemblies 42 described herein. Theattachment assembly 42 enables thefacemask 24 to absorb a high percentage of impact energy. - The shock-absorbing
facemask 24 embodiments described herein greatly reduce the amount of impact energy transferred from thefacemask 24 to theshell 22. This accomplishment is achieved through the structural design of theattachment assemblies 42 and/or through the materials used to form theattachment assemblies 42. - While the preferred embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the scope of the invention. For example, while the embodiments described herein are illustrated in a catcher's helmet, the principles of the present invention could also be used for practically any other helmet that includes a facemask. Accordingly, it will be intended to include all such alternatives, modifications and variations set forth within the scope of the appended claims.
