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.
Before embodiments of the invention are explained in detail, it is to be understood that the invention is in no way limited in its application to the details of construction and/or the arrangements of the components set forth in the following description or illustrated in the drawings. 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,
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 a bridge member 20 in the form of an upper cross bar which is operatively secured to the helmet shell 12 at the frontal connections 18. By way of example only, and not limitation,
As best seen through joint reference to
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 the bridge member 20 when the spring clip 24 is in an open i.e., uncompressed condition as illustrated in
As will be appreciated, the bridge member 20 may be inserted or removed through the forward opening 40 by applying an opening force to the lockdown leg 30 and raising the lockdown leg 30 away from the platform base 28 to widen the forward opening 40. Upon removal of the opening force, the spring clip 24 will thereafter return to the illustrated unbiased state shown in
As best illustrated in
In the illustrated exemplary configuration, the platform base 28 includes a raised surface 50 disposed in surrounding relation to the retention slot 46. Thus, when the screw 54 is moved into the retention slot 46, 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.
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 the helmet shell 12 in combination with cooperating screw 54 which extends in threaded relation into the T-nut 52. The screw 54 is accessible for tightening or loosening manipulation through an opening in the lockdown leg 30. As the screw 54 is advanced into the T-nut 52, the downwardly facing surface of the head of the screw 54 will press against the raised surface 50. This downward pressure, in turn, causes the lower surface of the platform base 28 of the spring clip 24 to be pressed against the outer opposing surface of the helmet shell 12. Moreover, the sidewalls and lower legs 56 of the T-nut 52 will spread outwardly so as to further enhance the locking relation between the T-nut 52 and the helmet shell 12.
As best illustrated through joint reference to
As shown, in the exemplary construction the lockdown leg 30 has a generally dogleg profile including a proximal platform surface 57 and a distal platform surface 59 disposed forward of the proximal platform surface. A ramp segment 61 extends between the proximal platform surface 57 and the distal platform surface 59 with an access opening in the ramp segment for manipulation of the screw 54. Referring to
In the illustrated arrangement, a locking arm designated generally as 74 extends upwardly away from the platform base 28. As shown, the locking arm 74 includes an angled head 76 having a half arrowhead profile adapted for receipt through the acceptance slot 70 when the lockdown leg 30 is moved to a closed position. Specifically, as best seen in

As described previously in relation to the earlier embodiment, the spring clip 124 includes a U-shaped spring segment 134. When the lockdown leg 130 is urged towards the platform base 128, the U-shaped spring segment 134 is placed into compression. The stored potential energy in the U-shaped spring segment 134 thereafter continuously urges the biasing leg 130 away from the underlying platform base 128 so as to achieve a substantially force neutral condition.
In practice, with the pop out fastener 126 extending between the helmet shell 112 and the spring clip 124, the camming screw 188 may be pressed downwardly and rotated such that the ear members 190 follow the cam tracks 192 within the cam lug 186. With the screw 188 in the fully inserted condition, the ear members 190 will reside in opposing relation to stop surfaces 194 (only one shown). In this condition, the biasing force applied by the spring clip 124 will thereafter urge the screw 188 continuously outward. In this tensioned state, shown in
In the event that it is desired to release the spring clip 124 from the locked relationship shown in
