1. Field of the Invention
The present invention relates generally to the field of protective helmets, and in particular, to a new and useful device for releasable attachment of a faceguard to a helmet shell.
2. Background of the Invention
In many sports, it is desirable for participants to wear a helmet shell to protect against head injury as a result of collisions. This is particularly the case in youth sports. It may also be desirable to protect the face by providing a generally cage-like faceguard across the front of the helmet shell. This provides frontal protection while retaining substantial frontal visibility. Such combinations of helmet shells and faceguards may be used in a number of sports, including football, lacrosse, baseball, fast-pitch softball, hockey, and the like.
In the event of injury, the faceguard may impede the ability of medical personnel to render assistance, as they will be unable to directly access the injured player's face to conduct tests and render treatment with the helmet shell and faceguard in place. The presence of a faceguard may also make it difficult to administer emergency aid such as, for example, 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. 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 remove the faceguard from the helmet shell prior to administering treatment. However, such removal tends to be relatively time-consuming and, in an emergency situation, complex. Thus, there is a need for a faceguard attachment system which permits rapid displacement of the faceguard without requiring removal of the entire helmet shell.
U.S. publication no. 2012/0011686 by Duong attempts to address these issues by teaching clips for securing a face mask to an article of head gear, and for releasing the face mask without the need for any special tools or equipment. The reference teaches that the clip may comprise a base and a retaining member that is pivotably coupled to the base. When the retaining member is engaged with the base, structure on the base prevents the retaining member from pivoting open, thus securing the face mask within the clip. To disengage the retaining member and release the face mask from the clip, a user may squeeze or flex a portion of the base, which causes the retaining member to disengage and pivot open.
Among other things, the reference fails to teach a shock stabilizer, or any other piece made of a material softer than the base or retaining member. Thus, upon impact there is no “give” in the device and such is important for allowing for effective absorption of impact.
U.S. publication no. 2010/0251464 by Parisi also attempts to address the problem. The reference teaches 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.
This device relies on a locking-arm-and-latch structure. The locking arm includes an angled head having a half arrowhead profile adapted for receipt through an acceptance slot (see
Thus, a need remains for further advancements in the field of helmet design, in particular for a face guard securing device which provides optimal securement of the face guard to the helmet, but which can be quickly and easily released.
Accordingly, one of the various objects of the invention is to provide a device for effectively securing a faceguard to a helmet.
It is also an object of the present invention to provide a device which allows for quick removal of the faceguard from the helmet.
The present invention is a quick-release face guard retaining device having a cooperating base and a latch.
The base has an overlying portion and an underlying portion. It has an opening in the underlying portion for connecting the device to a helmet by, for example, a screw and T-nut.
There is a grommet located in the opening of the base, the grommet defining a grommet opening. There is, in typical embodiments, a spacer located in the grommet opening. The grommet is typically a shock-absorbing disc. The shock-absorbing disc has a platform base and a raised surface. The raised surface is typically composed of two opposed crescents arranged to accommodate a curvature of the spacer. The grommet is, in certain embodiments, made of SURLYN.
The device also has a shock stabilizer located in a shock stabilizer-receiving groove of the base. The shock stabilizer is of a softer material than the base. For example, the shock stabilizer maybe made of rubber, and the base made from a thermoplastic polymer, such as a hard polycarbonate.
The latch is connected to the base in a hinged manner, and has a hooked part at one end.
The base, shock stabilizer and latch together define a receiving aperture in a closed condition for securing a faceguard wire in the device.
The device also has a clip disposed in between the base and the latch. The clip has curved parts at a first end and at a second end. The clip is secured within a clip-receiving part of the base at the first end and within a clip-receiving part of the latch at the second end. The clip exerts closing forces on the latch and the base, so that, overall, the retaining device is biased to a closed condition.
For added security, the present quick release retaining device may be locked. There is a sliding bar located in a bar-receiving groove of the base. The latch also has a sliding bar receiving groove. The groove of the latch is located such that, when the device is in the closed position, the grooves of the base and the latch are aligned.
The device is in the locked condition when the sliding bar-receiving grooves of the latch and base are aligned, and the sliding bar is located within a common groove formed by the aligned bar-receiving grooves of the latch and the base.
The sliding bar has an opening provided with a pin for enhanced locking. The sliding bar receiving groove of the base is provided with a pin-receiving cavity. The pin and the pin receiving cavity are oriented such that, when the sliding bar is pushed over the latch, the pin slides into the pin-receiving cavity. The pin and the pin-receiving cavity cooperate to provide a resistance to movement of the sliding bar away from the latch. The pin is forced from the pin-receiving cavity upon application of force against the sliding bar greater than the resistance provided by the cooperation of the pin and the pin-receiving cavity
The sliding bar may also be used to set the device in an open condition. The device is set in the open condition by pulling the sliding bar from of the aligned bar-receiving grooves, pulling the latch away from the base, pushing the sliding bar back through the a bar-receiving groove of the base so that it extends underneath the latch, and releasing the latch to rest on the sliding bar.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.
Referring now to the drawings,
As best seen by reference to
The curved portion 16 has a receiving groove Jul. 16, 2014 defined therein which receives a shock stabilizer 22. As seen in
In a typical embodiment, the shock stabilizer 22 is made of a softer material than the material from which the base 12 is made. The relative softness of the shock stabilizer 22 allows for some give, in the event of impact against the faceguard from an axially-opposed force, such as from another helmet or the ground. Preferably, the shock stabilizer 22 is made of rubber and the base 12 is made of a hard polycarbonate. These are non-limiting examples, as the base 12 and shock stabilizer 22 may each be made of any convenient material such that there is a differential in hardness between them.
As seen in
The latch 28 has a hooked part 30. In the locked position, the hooked part 30 presses the faceguard wire against the underlying portion 14 of the base 12 and against the shock stabilizer 22.
Thus, when the hooked part 30 is in contact with the base 12, the latch 28, the base 12, and the shock stabilizer 22 define a receiving aperture 32 for enclosing the wire of a faceguard. In a preferred embodiment, the receiving aperture 32 has an arcuate cross-section. However, it is within the scope of the invention for the receiving aperture 32 to have a cross section of any convenient shape, in accordance with the profile of the particular faceguard wire to be accommodated.
The base 12 and the latch 28 are further secured by a substantiality C-shaped clip 46. As shown in
The retaining device 10 is also provided with a sliding bar 48 located in a bar-receiving groove 50. As best seen in
As noted, the clip 46 exerts constant closing forces on the latch 28 and the base 12, which biases the retaining device 10 in the closed condition. In order to set and maintain the retaining device in an open condition, a user moves the sliding bar 48 out of the aligned bar-receiving grooves 50, 52. The user then pulls the hooked part 30 of the latch 28 away from the underlying portion 14 of the base 12. With the latch 28 in a raised position, the user pushes the sliding bar 48 back through the bar-receiving groove 50 in the overlying portion 18 of the base 12, so that it extends underneath the latch 28. When the latch 28 is released, it rests on the sliding bar 48, leaving the retaining device 10 in the open condition.
As an added feature for securing the sliding bar 48 over the latch 28, the sliding bar 48 has a hole 66 which is provided with a locking pin 68. In operation, when the sliding bar 48 is pushed over the latch, the pin 68 slides into a receiving cavity 70 in the overlying portion 18 of the base 12, and locks into place. This feature provides an additional measure for keeping the latch 28 down, in event of impact against the faceguard. When the sliding bar 48 is deliberately pushed away from the latch 28 with sufficient force, the pin 68 is forced out of the receiving cavity.
Typical embodiments include a grommet 58 located in an opening 78 in the base. The retaining device 10 may be secured to a sports helmet by a screw 100 passed through an opening 56 in the grommet 58. The screw 100 is passed further into a T-nut 110 inside the sports helmet (not shown). The screw 100 and T-nut 110 fix the base 12 to the helmet shell. In certain of these embodiments, there is a spacer 60 located in the opening 56 of the grommet 58.
In typical embodiments, the grommet 58 is shock-absorbing disc having a two-tiered structure, including a platform base 62 and a raised surface 64, as best understood with reference to
