Definitions

  • Modern hockey helmets typically include a solid, high density polyethylene shell with internal padding for protecting the wearer's head.
  • Hockey helmets also generally include a fit system to aid in properly fitting a helmet on a wearer.
  • many modern helmets include two-piece shells that are longitudinally movable relative to each other, and an internal lateral fit system, for adjusting the fit of the helmet on the wearer's head.
  • An example of such an adjustable helmet is described in U.S. Patent Application No. 12/191 ,000, filed August 13, 2008, which is incorporated herein by reference.
  • Hockey helmets also typically include earpieces for protecting a wearer's ears.
  • these earpieces are attached to the helmet shell via multiple screws, threaded fasteners, and other components such that they are removable (in other helmets, the earpieces are molded as part of the shell and are not removable).
  • Players commonly remove the earpieces to improve the overall comfort of the helmet and to improve communication with other players, coaches, and game officials.
  • players or trainers first need to remove the screws and other components. During this process, the screws, threaded fasteners, or other components frequently fall out of the helmet or into the helmet itself, making the removal process cumbersome.
  • a hockey helmet includes earpieces that are readily removable from the helmet without the need for tools or other objects, and without the need to remove screws or other components.
  • FIG. 1 is a side-perspective view of a hockey helmet including removable earpieces.
  • FIG. 2 is a bottom-perspective view of the helmet shown in Fig. 1 .
  • FIG. 3 is a side-perspective view of the removable earpiece and earpiece retention mechanism of the helmet shown in Figs. 1 and 2.
  • Fig. 4 is a top-perspective view of the removable earpiece and earpiece retention mechanism shown in Fig. 3.
  • FIG. 5 is a rear-perspective view of the removable earpiece and earpiece retention mechanism shown in Figs. 3 and 4.
  • Fig. 6 is a rear view of one element of the retention mechanism shown in Figs. 3-5.
  • Fig. 7 is a side-perspective view of the helmet shown in Fig. 1 with the earpieces removed.
  • a hockey helmet 10 includes a shell 12 having a front region 14, side regions 16, a rear region 18, and a crown region 20.
  • the shell structure includes a foam layer 22 (or a layer of another suitable impact-absorbing material) sandwiched between a thin plastic outer layer 24 and a thin plastic inner layer 26.
  • the foam layer is preferably an expanded polypropylene (“EPP") material but could alternatively be an expanded polyethylene (“EPE”) material, or a combination of these materials, or could be any other suitable energy-absorbing material or combination of materials.
  • EPP expanded polypropylene
  • EPE expanded polyethylene
  • the thin plastic layers 24, 26 may be made of polycarbonate or another suitable material.
  • the thin plastic layers 24, 26 may each be formed from a single piece of plastic or may be formed from multiple pieces of plastic that are molded together. While other materials may be used, for ease of description, an EPP foam layer 22 sandwiched between two polycarbonate layers 24, 26 will be described herein.
  • the inner polycarbonate layer 26 may be partially or entirely omitted, particularly in a helmet in which a relatively thicker outer layer 24 is used.
  • the inner polycarbonate layer 26, for example, may cover only certain regions of the EPP foam 22, such as the front, rear, and lower side regions of the EPP foam 22. Including an inner polycarbonate layer 26 on at least some regions of the EPP foam 22 is generally desirable, as it provides a more stable, better energy-absorbing structure than does a shell that does not include any inner polycarbonate layer 26.
  • Comfort foam or other comfort padding is preferably included on an interior surface of the EPP foam 22 or polycarbonate layer 26 to provide a comfortable fit for the wearer.
  • the polycarbonate layers 24, 26 may be vacuum formed and trimmed to a desired shape, then put into a mold with a pre-molded EPP layer 22 for bonding or fusing the polycarbonate layers 24, 26 to the EPP layer 22.
  • the polycarbonate layers 24, 26 may be placed into an EPP mold and then insert molded or "in-molded" with the EPP foam.
  • the polycarbonate layer or layers may be injection molded and then bonded to a liner of EPP foam.
  • Vacuum forming or insert molding generally are preferred over injection molding, as these processes allow for lighter and thinner plastic layers than does a typical injection molding process. It has been found, for example, that the inner and outer polycarbonate layers 24, 26 may be formed from sheets having a thickness as low as 0.7mm (which may become approximately 2mm thinner after undergoing a vacuum forming and molding process), whereas traditional injection molded helmets typically include a plastic shell having a thickness of approximately 1 .8 to 3mm. Any of the processes described herein, or another suitable process, however, may be used to construct the helmet shell 12.
  • the polycarbonate layers may be formed using combinations of two or more of these processes.
  • the outer layer 24 may be formed using an injection molding process while the inner layer may be formed using a vacuum forming process.
  • the upper regions of the outer layer 24 may be formed using an insert molding process while lower regions of the outer layer 24 may be formed using an injection molding process.
  • the helmet 10 includes a removable earpiece 30 on each side of the helmet 10.
  • the earpiece 30 is preferably made of a plastic material but could be made of any other suitable material.
  • the earpiece 30 may be transparent, translucent, or opaque.
  • the earpiece 30 preferably includes an opening 31 through which sound may be transmitted to the wearer's ear.
  • Each earpiece 30 is removably secured to a retention mechanism 35, which preferably is made of a nylon or plastic material, or another suitable material.
  • the retention mechanism 35 may be embedded within the EPP foam layer 22 during molding of the helmet 10.
  • the retention mechanism 35 alternatively may be an integral part of the plastic portion of the helmet shell itself, particularly if all or part of the shell is a thicker, injection molded component.
  • the helmet shell may be a hybrid including thin, plastic layers on upper regions of the EPP foam, and including thicker, injection molded plastic layers on lower regions of the EPP foam, with the retention features to which the earpieces 30 are attachable integrally molded with the lower injection molded regions.
  • the injection molded lower regions may be bonded or mechanically attached, via rivets or other attachment elements, to the EPP foam layer 22.
  • the retention mechanism 35 may include a single piece or multiple pieces.
  • the retention mechanism 35 includes a first retention element 36 and a second retention element 38 spaced apart from the first retention element 36.
  • the first and second retention elements 36, 38 each include a rail 34 or other suitable retention member projecting into the space between the retention elements 36, 38.
  • the earpiece 30 correspondingly includes a pair of longitudinal openings or channels 32 that slidably engage the rails 34.
  • the rails may be included on the earpiece, and the corresponding channels may be included in the retention elements 36, 38, such that the rails will not be apparent on the shell when the earpieces are removed.
  • one or more of the rails 34 optionally include an opening 40.
  • the earpiece 30 includes arms 42 having tabs or similar structures on inner surfaces thereof for engaging the openings 40 when the earpiece 30 is positioned on the rails 34.
  • Such an arrangement allows the earpiece 30 to snap or click into place such that it remains in position on the rails 34 when the helmet 10 is subjected to contact.
  • Other arrangements such as including
  • corresponding raised ridges or bumps on the rails 34 and on internal regions of the channel-defining portions of the earpiece 30, may alternatively be used to hold the earpiece 30 in position.
  • the earpiece 30 may be attached or removed from the helmet 10 by sliding the channels 32 along the rails 34 in the appropriate direction. If the rails include openings 40 or other mating regions that engage with the arms 42 or other portions of the earpiece 30, a small amount of force will be required to move the earpiece 30 into and out of the fully attached position.
  • Fig. 7 shows the helmet 10 with the earpieces 30 removed from the helmet 10.
  • the retention mechanism 35 may include ear loop supports 50 that define openings through which ear loops 52 may pass.
  • the ear loop supports 50 provide structural anchors to which the ear loops 52 may be secured.
  • the ear loop supports 50 are particularly beneficial when the helmet includes an EPP layer 22 and one or more thin polycarbonate layers 24, 26 (or no polycarbonate layers at all), since the EPP and thin polycarbonate layers 24, 26 do not provide as much structural support for the ear loop attachments as does a thicker, injection molded shell.
  • the ear loop supports 50 which are preferably embedded in the EPP layer 22, provide strong anchors for the ear loops that aid the helmet 10 in meeting certification standards.
  • the retention mechanism 35 optionally further includes threaded fasteners 55 for receiving screws used to attach an optional visor or faceguard (or other component) to the helmet 10.
  • the threaded fasteners 55 are preferably made of a metal material but may be made of any other suitable material.
  • Each threaded fastener is preferably over-molded in a plastic housing 56 that projects outwardly from the retention mechanism 35.
  • the upper, flat surface of each housing 56 acts as a shoulder against which a screw head or attached visor or faceguard may rest.
  • the housings 56 are preferably attached to teeth or arms 57 that aid in resisting rotation of the retention mechanism 35 when screws are threaded into or out of the fasteners 55. Because the retention mechanism 35 is embedded in the EPP foam 22, the threaded fasteners 55 will not fall into the helmet 10 or otherwise move when screws are removed from the fasteners 55.
  • the helmet shell includes three openings or holes 58 on each side of the helmet in which three fastener housings 56 are positioned. Any number of holes 58 may be included but most existing face guards require two or three attachment points on each side of the helmet 10 for connecting the visor or faceguard to the helmet 10.
  • the screws may be threaded out of the fasteners 55 and the openings in the visor or face guard may be aligned with the holes 58. The screws may then be threaded back into the fasteners 55 to secure the visor or face guard to the helmet 10 (in some instances, longer screws than the original helmet screws may be required to accommodate the thickness of a given visor or face guard).
  • Each retention mechanism 35 optionally includes a rear tab 60 or other attachment element including an opening 62 that provides an attachment point for a fitting element in the interior of the helmet.
  • each the tab 60 preferably projects through an opening or slit in the EPP foam 22 into the helmet's interior.
  • a projecting post or similar feature on a fitting element may be secured to the tab 60 by pushing it through the large region of the opening 62 and pulling it into the smaller region of the opening 62.
  • One or more adjustable bands or similar fitting devices may be attached between two fitting elements to provide an adjustable fit system.
  • the helmet features described herein provide for a lightweight helmet that optionally may be molded into one piece as opposed to a traditional two-piece shell.
  • the helmet does not include the gaps that are generally present in a two-piece adjustable shell.
  • a one-piece shell also generally includes fewer moving parts that could potentially come loose, rattle, and so forth.
  • the earpieces 30 are much easier to remove and re-attach than are conventional earpieces, since they do not require tools or other objects to effectuate their removal.
  • One or more of the helmet features described herein may be used in other helmets, such as batters' helmets, pitchers' helmets, catchers' helmets, lacrosse helmets, football helmets, and so forth.
  • a batter's helmet could be constructed by in-molding a layer of EPP foam between a pair of thin polycarbonate layers.
  • attachment of a visor or face guard could be embedded in the EPP foam of the batter's helmet.
