Definitions
- the present invention relates generally to faceguard systems for protective helmets, and is more particularly directed to a system for releasable attachment of a faceguard to a helmet shell.
- the attachment system incorporates a selectively releasable spring clip incorporating a biasing lockdown leg and a retaining pocket adapted to support a crossbar member of the faceguard. Upon release of the lockdown leg, the crossbar member may be rotated within the retaining pocket and the faceguard may be pivoted relative to the helmet shell.
- helmet shells and faceguards may be used in American football, lacrosse, baseball, fast-pitch softball, rodeo, and the like.
- a faceguard While the presence of a faceguard may be desirable to prevent facial injury, in the event that a player does become injured, the presence of the faceguard may hinder the ability of medical personnel to render assistance. Specifically, with the helmet shell and faceguard in place, emergency personnel will be unable to reach the injured player's face to conduct tests and render treatment. By way of example only, the presence of a faceguard may make it difficult to administer emergency aid such as mouth-to-mouth resuscitation. While access to the player's face may be achieved by removing the entire helmet shell with the faceguard attached, such removal may be undesirable in the event of a suspected brain or spinal injury. Specifically, when such injuries are suspected, the general recommendation is to minimize head and neck movement.
- the present invention provides advantages and alternatives over the prior art by providing a system for operative connection of a faceguard to a helmet shell with the faceguard being held within a selectively releasable clamp operatively secured to the helmet shell. Upon release of the clamp, the faceguard may be rotated away from the user's face so as to permit access by emergency personnel without the need to remove the helmet shell.
- the present invention provides an attachment system adapted to operatively connect a faceguard to a helmet shell.
- the attachment system includes a compressible spring clip operatively engaging an adjustable connector extending outwardly from an exterior surface of the helmet shell such that the spring clip is held in overlying relation to the helmet shell.
- the spring clip is adapted to selectively clamp a bridge member of the faceguard.

- the platform base and the lockdown leg cooperatively define a compressible pocket adapted to cradle the bridge member between the platform base and the lockdown leg.
- the lockdown leg moves in pivoting relation between an open condition in which the bridge member is rotatable within the pocket and a closed condition in which the bridge member is clamped against rotation within the pocket.
- the attachment system further includes a selectively engageable latch structure adapted to hold the lockdown leg in the closed condition, such that upon release of the latch structure, the spring segment urges the lockdown leg away from the platform base to the open condition, such that the bridge member is rotatable within the pocket.

- the raised surface 50 may apply an upward biasing force against the underside of the screw head to aid in forming a locked relation between the spring clip 24 and the underlying helmet shell 12 . That is, the raised surface 50 acts as a wedge which is held in compression between the helmet shell 12 and a downwardly facing surface of the screw head. With the raised surface 50 held in compression between the helmet shell 12 and a downwardly facing surface of the screw head, slippage is minimized between the spring clip 24 and the underlying helmet shell.

Abstract
An attachment system for operative connection of a faceguard to a helmet shell with the faceguard being held within a selectively releasable clamp operatively secured to the helmet shell. The attachment system includes a compressible spring clip held in overlying relation to the helmet shell. The spring clip is adapted to selectively clamp a bridge member of the faceguard. A selectively engageable latch structure holds the spring clip in the closed condition. Upon release of the latch structure, the spring clip is urged to the open condition, such that the faceguard may be rotated away from a user's face.
Description
- This application claims the benefit of provisional application No. 61/166,829, filed Apr. 6, 2009, the contents of which are incorporated by reference as if set forth herein in their entirety.
- The present invention relates generally to faceguard systems for protective helmets, and is more particularly directed to a system for releasable attachment of a faceguard to a helmet shell. The attachment system incorporates a selectively releasable spring clip incorporating a biasing lockdown leg and a retaining pocket adapted to support a crossbar member of the faceguard. Upon release of the lockdown leg, the crossbar member may be rotated within the retaining pocket and the faceguard may be pivoted relative to the helmet shell.
- In many sporting events it is desirable for participants to wear a helmet shell to protect against accidental injury as a result of contact with equipment or other participants during an athletic contest. It may also be desirable to provide a generally cage-like faceguard across a forward portion of the helmet shell to provide the user with frontal protection while nonetheless providing substantial frontal visibility. By way of example only, and not limitation, such combinations of helmet shells and faceguards may be used in American football, lacrosse, baseball, fast-pitch softball, rodeo, and the like.
- While the presence of a faceguard may be desirable to prevent facial injury, in the event that a player does become injured, the presence of the faceguard may hinder the ability of medical personnel to render assistance. Specifically, with the helmet shell and faceguard in place, emergency personnel will be unable to reach the injured player's face to conduct tests and render treatment. By way of example only, the presence of a faceguard may make it difficult to administer emergency aid such as mouth-to-mouth resuscitation. While access to the player's face may be achieved by removing the entire helmet shell with the faceguard attached, such removal may be undesirable in the event of a suspected brain or spinal injury. Specifically, when such injuries are suspected, the general recommendation is to minimize head and neck movement. To avoid moving the player's head under such conditions, it may be necessary to entirely remove the faceguard from the helmet shell prior to administering treatment. However, such removal tends to be relatively time-consuming and complex. In light of such issues, there is a need for a faceguard attachment system which permits rapid displacement of the faceguard without requiring removal of the entire helmet shell.
- The present invention provides advantages and alternatives over the prior art by providing a system for operative connection of a faceguard to a helmet shell with the faceguard being held within a selectively releasable clamp operatively secured to the helmet shell. Upon release of the clamp, the faceguard may be rotated away from the user's face so as to permit access by emergency personnel without the need to remove the helmet shell.
- In accordance with one exemplary aspect, the present invention provides an attachment system adapted to operatively connect a faceguard to a helmet shell. The attachment system includes a compressible spring clip operatively engaging an adjustable connector extending outwardly from an exterior surface of the helmet shell such that the spring clip is held in overlying relation to the helmet shell. The spring clip is adapted to selectively clamp a bridge member of the faceguard. The spring clip includes a platform base, a pivoting lockdown leg disposed above the platform base and a biasing spring segment operatively connecting the platform base and the lockdown leg. The platform base and the lockdown leg cooperatively define a compressible pocket adapted to cradle the bridge member between the platform base and the lockdown leg. The lockdown leg moves in pivoting relation between an open condition in which the bridge member is rotatable within the pocket and a closed condition in which the bridge member is clamped against rotation within the pocket. The attachment system further includes a selectively engageable latch structure adapted to hold the lockdown leg in the closed condition, such that upon release of the latch structure, the spring segment urges the lockdown leg away from the platform base to the open condition, such that the bridge member is rotatable within the pocket.
- In accordance with another exemplary aspect, the present invention provides an attachment system adapted to operatively connect a faceguard to a helmet shell. The attachment system includes a compressible spring clip operatively engaging an adjustable connector extending outwardly from an exterior surface of the helmet shell such that the spring clip is held in overlying relation to the helmet shell. The spring clip is adapted to selectively clamp a bridge member of the faceguard. The spring clip includes a platform base, a pivoting lockdown leg disposed above the platform base and an arcuate spring segment operatively connecting the platform base and the lockdown leg. The arcuate spring segment at least partially surrounds a compressible pocket adapted to cradle the bridge member between the platform base and the lockdown leg. The lockdown leg moves in pivoting relation between an open condition in which the bridge member is rotatable within the pocket and a closed condition in which the bridge member is clamped against rotation within the pocket. The lockdown leg includes a latch acceptance opening disposed adjacent to a distal edge of the lockdown leg. The attachment system further includes a selectively engageable latch structure adapted to hold the lockdown leg in the closed condition. Upon release of the latch structure, the spring segment urges the lockdown leg away from the platform base to the open condition. The latch structure includes a resilient locking arm extending upwardly from the platform base. The locking arm includes a post portion and a distal angled head adapted for snap-in insertion through the latch acceptance opening in the lockdown leg. The angled head includes a chamfered camming surface and an undercut disposed between the post portion and the chamfered camming surface. The chamfered camming surface includes a tool-engaging cavity oriented to face outwardly towards the distal edge of the lockdown leg following insertion through the latch acceptance opening in the lockdown leg.
- In accordance with yet a further exemplary aspect, the present invention provides an attachment system adapted to operatively connect a faceguard to a helmet shell. The attachment system includes a compressible spring clip operatively engaging an adjustable connector extending outwardly from an exterior surface of the helmet shell such that the spring clip is held in overlying relation to the helmet shell. The spring clip is adapted to selectively clamp a bridge member of the faceguard. The spring clip includes a platform base, a pivoting lockdown leg disposed above the platform base and an arcuate spring segment operatively connecting the platform base and the lockdown leg. The arcuate spring segment at least partially surrounds a compressible pocket adapted to cradle the bridge member between the platform base and the lockdown leg. The lockdown leg moves in pivoting relation between an open condition in which the bridge member is rotatable within the pocket and a closed condition in which the bridge member is clamped against rotation within the pocket. The attachment system further includes a selectively engageable latch structure adapted to hold the lockdown leg in the closed condition, such that upon release of the latch structure, the spring segment urges the lockdown leg away from the platform base to the open condition, such that the bridge member is rotatable within the pocket. The latch structure includes a camming screw having a tool-engaging head portion disposed across an upper surface of the lockdown leg. The connector includes a camming lug including partial turn camming tracks adapted to engage the camming screw such that the camming screw is latched in place by compression and rotation within the camming lug.

Rather, the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for purposes of description only and should not be regarded as limiting. Accordingly, the use herein of “including”, “comprising’, and variations thereof is meant to encompass the items listed thereafter and equivalents as well as additional items and equivalents thereof.
- Reference will now be made to the drawings wherein like elements are designated by like reference numerals in the various views. In this regard,
FIG. 1 illustrates anexemplary helmet 10 including ahelmet shell 12 and afaceguard 14. As shown, in the illustrated exemplary construction thefaceguard 14 is held to thehelmet shell 12 at releasable side connections 16 (only one shown) and at one or morefrontal connections 18 disposed at a portion of thehelmet shell 12 generally overlying a user's forehead. Accordingly, during use, both theside connections 16 and thefrontal connections 18 are outside the field of vision of a user and do not interfere with performance. As will be appreciated, while the illustratedhelmet 10 is a style typically used for American football, the present invention is likewise adapted for use with virtually any helmet style as may be desired. - As noted previously, in the event that a user suffers an injury, it may be desirable to displace or remove the
faceguard 14 to permit medical personnel to access a user's face. Moreover, it may be desirable to carryout such displacement or removal without the need to move the user or remove the helmet. - As illustrated, the
faceguard 14 may include abridge member 20 in the form of an upper cross bar which is operatively secured to thehelmet shell 12 at thefrontal connections 18. By way of example only, and not limitation,FIG. 2 illustrates one exemplary arrangement for thefrontal connections 18 used to hold thebridge member 20 of afaceguard 14 in place relative to ahelmet shell 12. As shown, in the exemplary arrangement ofFIG. 2 , thefrontal connection 18 includes a variable tension clasp in the form of alatchable spring clip 24 adapted to hold thebridge member 20 in a cradling relationship. The frontal connection further includes aconnector 26 adapted to secure thespring clip 24 in place at the surface of thehelmet shell 12. - As best seen through joint reference to
FIGS. 2 , 3, and 5, thespring clip 24 has a generally hairpin construction including aplatform base 28 and an overlying spring-biasedlockdown leg 30. An intermediate compressibleU-shaped spring segment 34 extends between theplatform base 28 and thelockdown leg 30 to define a retainingpocket 36 for housing thebridge member 20. TheU-shaped spring segment 34 normally supports thelockdown leg 30 at an open position as shown inFIG. 2 . Accordingly, when thelockdown leg 30 is moved towards theplatform base 28, theU-shaped spring segment 34 will apply a biasing recovery force urging thelockdown leg 30 back towards the neutral open position. - In the illustrated exemplary embodiment, the retaining
pocket 36 has a generally arcuate profile with an internal diameter slightly greater than the outer diameter of thebridge member 20 when thespring clip 24 is in an open i.e., uncompressed condition as illustrated inFIGS. 2 and 5 . Thelockdown leg 30 includes an inwardly projectingprotuberance 38 having a rearward surface which defines a portion of the retainingpocket 36. In this arrangement, the retainingpocket 36 has aforward opening 40 extending generally between the apex of theprotuberance 38 and the opposingplatform base 28. In the illustrated, exemplary arrangement, this opening has a width slightly less than the cross-sectional diameter of thebridge member 20. Accordingly, when the biasingleg 30 is in the open, neutral position, thebridge member 20 may rotate substantially freely within the retainingpocket 36 while nonetheless being blocked from the removal through theforward opening 40. - As will be appreciated, the
bridge member 20 may be inserted or removed through theforward opening 40 by applying an opening force to thelockdown leg 30 and raising thelockdown leg 30 away from theplatform base 28 to widen theforward opening 40. Upon removal of the opening force, thespring clip 24 will thereafter return to the illustrated unbiased state shown inFIGS. 2 and 5 . In this regard, it is contemplated that thespring clip 24 will preferably be formed from a suitable resilient plastic material such as nylon, polypropylene, or the like to facilitate resilient bending and recovery. - As best illustrated in
FIGS. 5 and 6 , theplatform base 28 includes a keyway access opening designated generally as 42 for matedly accepting theconnector 26. In the illustrated arrangement, the keyway access opening 42 includes a largediameter base portion 44 and a retention slot 46 (FIG. 3 ) projecting forward from thebase portion 44. Thus, the head of ascrew 54 forming a part of theconnector 26 may be inserted through the relatively widediameter base portion 44 and may then be moved relative to theplatform base 28 such that the shaft of thescrew 54 resides within theretention slot 46. - In the illustrated exemplary configuration, the
platform base 28 includes a raisedsurface 50 disposed in surrounding relation to theretention slot 46. Thus, when thescrew 54 is moved into theretention slot 46, the raisedsurface 50 may apply an upward biasing force against the underside of the screw head to aid in forming a locked relation between thespring clip 24 and theunderlying helmet shell 12. That is, the raisedsurface 50 acts as a wedge which is held in compression between thehelmet shell 12 and a downwardly facing surface of the screw head. With the raisedsurface 50 held in compression between thehelmet shell 12 and a downwardly facing surface of the screw head, slippage is minimized between thespring clip 24 and the underlying helmet shell. - By way of example only, and not limitation, in the illustrated, exemplary arrangement, the
connector 26 may be in the form of a T-nut 52 which extends through an opening in thehelmet shell 12 in combination with cooperatingscrew 54 which extends in threaded relation into the T-nut 52. Thescrew 54 is accessible for tightening or loosening manipulation through an opening in thelockdown leg 30. As thescrew 54 is advanced into the T-nut 52, the downwardly facing surface of the head of thescrew 54 will press against the raisedsurface 50. This downward pressure, in turn, causes the lower surface of theplatform base 28 of thespring clip 24 to be pressed against the outer opposing surface of thehelmet shell 12. Moreover, the sidewalls andlower legs 56 of the T-nut 52 will spread outwardly so as to further enhance the locking relation between the T-nut 52 and thehelmet shell 12. - As best illustrated through joint reference to
FIGS. 5 , 6, 7, and 8, in the exemplary arrangement, thelockdown leg 30 may be pressed inwardly to establish a latched connection with the underlying platform base 28 (FIGS. 7 , 8). In this latched condition, the openU-shaped spring segment 34 is compressed about the perimeter of thebridge member 20. In this compressed relation, thebridge member 20 is substantially precluded from rotational movement relative to the surrounding surfaces of the retainingpocket 36. At the same time, when thelockdown leg 30 is in the latched condition, the stored energy in theU-shaped spring segment 34 applies a continuous biasing force urging thelockdown leg 30 towards the open neutral condition. - As shown, in the exemplary construction the
lockdown leg 30 has a generally dogleg profile including aproximal platform surface 57 and adistal platform surface 59 disposed forward of the proximal platform surface. Aramp segment 61 extends between theproximal platform surface 57 and thedistal platform surface 59 with an access opening in the ramp segment for manipulation of thescrew 54. Referring toFIGS. 5 and 6 , in the illustrated exemplary embodiment, thelockdown leg 30 includes adepression 60 across a forward edge of thedistal platform surface 59. Thedepression 60 includes a generally flat bottom 62 with twolateral sidewalls rear wall 68 disposed about the bottom 62. As shown, thedepression 60 is open across its forward face. As illustrated, anacceptance slot 70 is disposed across thedepression 60 in transverse orientation to thelateral sidewalls - In the illustrated arrangement, a locking arm designated generally as 74 extends upwardly away from the
platform base 28. As shown, the lockingarm 74 includes anangled head 76 having a half arrowhead profile adapted for receipt through theacceptance slot 70 when thelockdown leg 30 is moved to a closed position. Specifically, as best seen inFIG. 6 , theangled head 76 includes a chamferedface 78 which is adapted to slide in camming action relative to the opposing forward edge of theacceptance slot 70 during insertion. As will be appreciated, during this insertion action, the lockingarm 74 will bend rearwardly and will then snap forward once the insertion is complete. In the fully inserted condition illustrated inFIG. 7 an undercut 80 of theangled head 76 is disposed in locked relation over a ledge defined by the bottom 62 of thedepression 60 forward of theacceptance slot 70. - As best seen in
FIGS. 6 and 8 , in the exemplary arrangement theangled head 76 includes acavity 82. When thelockdown leg 30 is in the locked condition illustrated inFIG. 8 , thecavity 82 faces outwardly away from therear wall 68 of thedepression 60. Thus, thecavity 82 is readily accessible through the open face of thedepression 60. With this arrangement, in the event that it is desired to disengage the locked relationship ofFIG. 8 , an insertion tool such as a ball point pen, screwdriver, or the like, may be inserted linearly into thecavity 82 to apply rearward pressure against theangled head 76. As the rearward force is applied, theangled head 76 moves until the undercut 80 no longer engages the bottom 62 of thedepression 60. Without this latching engagement, the stored energy in theU-shaped spring segment 34 causes thelockdown leg 30 to spring upwardly away from theplatform base 28 to the neutral condition illustrated inFIGS. 5 and 6 . In this condition, thebridge member 20 may then rotate freely within the retainingpocket 36. - Referring jointly to
FIGS. 1 and 9 , the benefit of the present attachment system may be clearly seen. As shown, by disengaging the locked relation of the biasingleg 30 to theplatform base 28, the bridge member is not compressed within the retainingpocket 36 and thefaceguard 14 may be rotated upwardly and away from the player's face so as to permit medical treatment. Moreover, since the locking relationship can be disengaged by a simple linear movement using a tool such as a screwdriver, ballpoint pen, or the like. Substantially no manipulation of the player's head is required. As will be appreciated, this may be particularly beneficial in the treatment of head and spinal injuries during which it is normally advisable to minimize head movement. -
FIGS. 10-12 illustrate another embodiment of the present invention. In these figures, elements corresponding to those previously described are designated by like reference numerals within a 100 series. As shown, in this arrangement, aspring clip 124 holds abridge member 120 of a faceguard (not shown). In the illustrated configuration, thespring clip 124 is secured to thehelmet shell 112 by a pop-out fastener 126 such as a quarter turn cam screw or the like. - As best seen through joint reference to
FIGS. 10 and 11 , a pop-out fastener extends between theplatform base 128 and anoverlying lockdown leg 130 of substantially dogleg profile. As shown inFIG. 12 , one exemplary pop-out fastener 126 includes a T-nut 152 having anut base 184 and a quarterturn cam lug 186 adapted to receive and retain the stem of acamming screw 188. As shown, thecam lug 186 includes generally “J” shaped cam tracks 192 adapted to receive and guide ear members 190 (only one shown) extending outwardly from the stem of thescrew 188. - As described previously in relation to the earlier embodiment, the
spring clip 124 includes aU-shaped spring segment 134. When thelockdown leg 130 is urged towards theplatform base 128, theU-shaped spring segment 134 is placed into compression. The stored potential energy in theU-shaped spring segment 134 thereafter continuously urges the biasingleg 130 away from theunderlying platform base 128 so as to achieve a substantially force neutral condition. - In practice, with the pop out
fastener 126 extending between thehelmet shell 112 and thespring clip 124, thecamming screw 188 may be pressed downwardly and rotated such that theear members 190 follow the cam tracks 192 within thecam lug 186. With thescrew 188 in the fully inserted condition, theear members 190 will reside in opposing relation to stop surfaces 194 (only one shown). In this condition, the biasing force applied by thespring clip 124 will thereafter urge thescrew 188 continuously outward. In this tensioned state, shown inFIGS. 10 and 11 , thespring clip 124 is held securely to theunderlying helmet shell 112. In addition, thebridge member 120 is substantially blocked against rotation. - In the event that it is desired to release the
spring clip 124 from the locked relationship shown inFIGS. 10 and 11 , thescrew 188 may be pressed inwardly and rotated counterclockwise to release the engagement. In this regard, as the screw is rotated, theear members 190 will follow the cam tracks 192 while thescrew 188 is urged outwardly by the stored potential energy in theU-shaped spring segment 134. Thus, thescrew 188 will move back to the position substantially shown inFIG. 12 . In this released condition, thebridge member 120 is no longer clamped. Accordingly, it can be rotated freely so as to permit the faceguard to be rotated away from a player's face without head movement. As will be appreciated, since thescrew 188 is released by a quarter turn, there is substantially no delay in gaining access to the player's face to administer treatment. - Of course, variations and modifications of the foregoing are within the scope of the present invention. Thus, it is to be understood that the invention disclosed and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All of these different combinations constitute various alternative aspects of the present invention. The embodiments described herein explain the best modes known for practicing the invention and will enable others skilled in the art to utilize the invention. the claims are to be construed to include alternative embodiments and equivalents to the extent permitted by the prior art.
