Definitions

  • the present invention relates to an ear protector for a hockey or lacrosse helmet.
  • Ear protectors are often made of a clear material in order to minimize their visual impact and thus provide a resemblance between recreational players and those with high skill level who do not wear ear guards. Such ear protectors include the features of the preamble of claim 1.
  • ear protectors For many years, the design of the ear protectors has not evolved because the United States ASTM norms required the presence of a protective foam piece covering the portion of the ear protector that may contact the ear due to an impact to the ear protector. Hence, prior ear protectors are transparent with a piece of foam of approximately 2mm in thickness affixed to the inner bottom portion of the ear protector.
  • the small foam piece of 2 mm in thickness is not presumed to offer great protection and the most frequent injury is a cut induced by the edges of the ear protector which are more or less sharp depending on the design of the piece and the rigidity of the material used.
  • Document US 2006/0212998 discloses an ear protector comprising a support member, a rigid protective outer cover and an inner pocket.
  • the inner pocket is formed of resilient material attached to the inner periphery of the support member.
  • U.S. Publication 2009/0188022 discloses a hockey helmet comprising an outer shell made of first and second plastic materials having respective first and second flexibilities. The second flexibility is greater from the first flexibility.
  • the outer shell has a front portion, a top portion, left and right portions comprising respective left and right projections extending downwardly in front of the respective left and right ears, a back portion and an occipital portion.
  • One of the left and right sections, the left and right projections, occipital portion or the front portion is partially made of the second plastic material overmolded onto the first plastic material while remaining of the outer shell is made of the first material only.
  • this reference does not relate to an ear protector.
  • a feature of the invention to diminish the risk of cutting by eliminating the sharp edges of the ear protector by providing a soft material (e.g. thermoplastic elastomer (TPE)) on a ear protector body made of a clear rigid material (e.g. polycarbonate (PC)), the soft material covering a portion of the bottom edge of the ear protector.
  • a soft material e.g. thermoplastic elastomer (TPE)
  • a ear protector body made of a clear rigid material (e.g. polycarbonate (PC)
  • an ear protector for a hockey or lacrosse helmet as specified in claim 1.
  • Figures 1 and 2 illustrate a head of a hockey or lacrosse player.
  • the head comprises a crown region CR, left and right side regions LS, RS, a top region TR, a back region BR and an occipital region OR.
  • the crown region CR has a front part that substantially corresponds to the forehead and a top part that substantially corresponds to the front top part of the head. In fact, the crown region CR generally corresponds to the frontal bone region of the head.
  • the left and right side regions LS, RS are approximately located above the ears of the player.
  • the occipital region OR substantially corresponds to the region around and under the external occipital protuberance of the head.
  • FIGS 3 and 4 show an adjustable helmet 10 for receiving the head of the hockey or lacrosse player.
  • the helmet 10 extends along a longitudinal axis A-A and comprises a front shell 12 and a rear shell 14 interconnected together.
  • the front shell 12 and rear shell 14 may be made of a relatively rigid material, such as polyethylene, NYLON, polycarbonate materials, thermoplastics, or thermosetting resins or any other suitable material.
  • the front and rear shells 12, 14 include a plurality of ventilation apertures that provide the added comfort of allowing air to circulate around the head of the player.
  • the front shell 12 has a first top portion for facing at least partially the top region TR of the player's head, a front portion for facing at least partially the crown region CR of the player's head, and left and right side portions extending rearwardly from the front portion for facing at least partially the left and right side regions LS, RS of the player's head.
  • the rear shell 14 has a second top portion for facing at least partially the top region TR of the player's head, a rear portion for facing at least partially the back and occipital regions BR, OR of the player's head, and left and right side portions extending forwardly from the rear portion for facing at least partially the left and right side regions LS, RS of the player's head.
  • the front shell 12 overlays left and right front inner pads 15, 16 while the rear shell 14 overlays left and right rear side inner pads 18, 20 and a rear top inner pad 22.
  • the left and right front inner pads 15, 16 face the crown region CR and face at least partially the left and right side regions LS, RS.
  • the left and right rear side inner pads 18, 20 at least partially face the left and right side regions LS, RS.
  • the rear top inner pad 22 faces the back and top regions BR, TR of the head.
  • the inner pads 15, 16, 18, 20, 22 may be made of shock absorbing materials such as expanded polypropylene (EPP) or expanded polyethylene (EPE). Other materials can also be used.
  • the front inner pads 15, 16 have a three-dimensional external configuration that matches the three-dimensional internal configurations of the front shell 12 and are mounted to the front shell 12 by any suitable means such glue, stitches, tacks, staples or rivets.
  • the left and right rear side inner pads 18, 20 and rear top inner pad 22 have three-dimensional external configurations that match the three-dimensional internal configurations of the rear shell 14 and are mounted to the rear shell 14 by any suitable means, such as glue, stitches, tacks, staples or rivets.
  • the helmet 10 may also comprise left and right comfort pads 24, 26 facing the left and right side regions LS, RS and located just above the ears and left and right comfort pads 28, 30 facing the left and right temple regions of the head.
  • the helmet 10 may further comprise left and right comfort pads 25, 27 located just above the ears and between the front and rear shells 12, 14.
  • the comfort pads 24, 25, 26, 27, 28, 30 may be made of soft materials such as polyvinyl chloride (PVC) or such a foam sold under the trade-mark PORON XRD. Other materials can also be used.
  • PVC polyvinyl chloride
  • Other materials can also be used.
  • the comfort pads 24, 25, 26, 27, 28, 30 may be affixed on the inner surface of the corresponding inner pads or shells by any suitable means, such as glue or an adhesive layer.
  • the helmet 10 also comprises left and right ear protectors 32 (32L: 32R) for protecting the ears of the player.
  • the ear protector 32 has a front portion 34, a top portion 36, a rear portion 38, a bottom portion 40 with a bottom edge 42, an inner side 44 and an outer side 46.
  • the rear portion 38 may comprise a rear extension 41 with a slot 43 extending along an axis generally parallel to the axis A-A.
  • the front portion 34 may also comprise a front extension 45 with one or two apertures 47.
  • the ear protector 32 may also comprise a central aperture 48 defined by an internal peripheral edge 50 and being adapted to be located generally adjacent the external auditory canal of the player's ear such that sounds may be more easily detected by the player.
  • the inner side 44 may define a recessed region 60 for facing the player's ear.
  • the ear protector 32 can be understood to have a generally curved arrangement proximate the player's ear such as to permit a comfortable fit or such that the recessed region 60 generally surrounds the player's ear.
  • the ear protector 32 may also be understood to present a raised region 70 along the outer side 46 of the ear protector 32, wherein the raised region 70 can generally be seen as being opposed to the recessed region 60.
  • the ear protector 32 shown in Figures 10 to 12 is made of a first clear rigid material and of a second softer material that is overmolded onto portions of the first material for covering at least partially specific portions of the ear protector 32.
  • a substantial part of the ear protector 32 is made of an ear protector body 132 being made of the first, relatively rigid, clear material, such as polycarbonate (PC), acrylic, clear polymer, polypropylene, SURLYN TM , or styrene-butadiene copolymer (SBC).
  • the ear protector body 132 has a bottom portion 140 with a bottom edge 142, an inner side 144 and an outer side 146 and an internal peripheral edge 150.
  • clear material cover a material for which one can see through the material (e.g. transparent material; translucent material).
  • the first material is polycarbonate (PC) having for example the following properties: tensile strength between 55MPa (8,000psi) and 83MPa (12,000psi) and Rockwell hardness between 70R and 121R.
  • the maximum temperature of the polycarbonate (PC) may be 121C° (250°F) and its minimum temperature may be -40C° (-40°F).
  • FIGS. 10 to 12 which show the ear protector 32 with the second soft material
  • at least a portion of the ear protector 32 is made of the second soft material that is overmolded onto the first material while the remaining of the ear protector 32 is made of the first material only.
  • the terms "soft material” cover a material that offers a greater flexibility and better shock absorbing properties that the first material.
  • the second material is more flexible than the first material and thus has a "softer feel" than the first material.
  • the second material may be selected in the group consisting of thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), polypropylene and medium density polyethylene (MDPE).
  • TPE thermoplastic elastomer
  • TPU thermoplastic polyurethane
  • MDPE medium density polyethylene
  • the second material may be made of medium density polyethylene such as MDPE 50.
  • the second material may be made of a thermoplastic elastomer (TPE) such as PEBAXTM 5533.
  • the second material may be polypropylene 7633U.
  • the second material is thermoplastic elastomer (TPE) having a durometer hardness between 40 Shore A and 60 Shore A.
  • the second material is overmolded onto the first material for covering at least partially the bottom edge 42.
  • the part of the bottom edge 42 that is made of the second material generally corresponds to the portion that is adapted to be generally adjacent the player's ear.
  • at least a portion of the bottom edge 42 is made of the second material overmolded onto the first material while remaining of the ear protector body 132 is made of the first material only.
  • the second material may also be overmolded onto other portions of the ear protector body 132 such that specific portions of the ear protector 32 are made of the second material overmolded onto the first material while remaining portions of the ear protector 32 are made of the first material only.
  • the overmolding of the second material onto the first material may be done such that at least a portion of the ear protector body 132 is covered on both the inner side 44 and the outer side 46 by the second material while the remaining of the ear protector body 132 may be covered on one side only. As such, a "sandwiched" arrangement can be seen between the first material and the second material in the portion of the ear protector body 132 which is covered on both sides by the second material.
  • the second material may be overmolded onto the first material for covering the inner and outer sides 144, 146 of the bottom edge 142 of the ear protector body 132 and for covering at least partially the inner side 144 of the ear protector body 132.
  • the portion of the inner side 44 that is made of the second material overmolded onto the first material generally corresponds to the portion that is adapted to be generally adjacent the player's ear such that the portion located below the central aperture 48 is substantially made of the second material overmolded onto the first material.
  • the overmolding of the second material onto the first material may imply that at least a portion of the inner side 144 and the internal peripheral edge 150 is covered by the second material (note the exposure of the internal peripheral edge 150 on Figure 8 in comparison to Figure 11 wherein the internal peripheral edge 50 has been covered with second material).
  • the outer side 146 of the ear protector body 132 is not at all covered by second material, thus permitting the overmolding of the second material onto the first material without a "sandwiched" arrangement.
  • such an arrangement can be adopted for the overmolding of the second material onto the first material for covering at least partially the internal peripheral edge 50 defining the central aperture 48 as best shown in Figure 11 .
  • the second material may be overmolded onto the first material such that only a portion of the inner side 144 of the ear protector body 132 is covered by the second material.
  • a portion of the recessed region 60 of the inner side 44 may be overmolded with second material such that the second material is thick enough to provide a substantial clearance between the player's ear and the internal peripheral edge 150.
  • the internal peripheral edge 150 may or may not be overmolded with second material. In embodiments wherein the internal peripheral edge 150 is not overmolded with second material, the clearance provided by the thickness of the second material may suffice to prevent contact between portions of the ear which would otherwise be likely to contact the internal peripheral edge 150 in the absence of second material.
  • the bottom edge 142 may comprise at least one indented region 160 for receiving the overmolded second material onto the first material such that once the second material has set onto the first material, the first material and the second material may define a flush arrangement between one another such that the bottom edge 42 of the ear protector 32 does not present significant discontinuities (see figures 10 and 11 ).
  • the overmolding of the second material onto the first material may present a discontinuous arrangement on the bottom edge 42 of the ear protector 32.
  • a flush arrangement between the second material and the first material may still be accomplished depending on the overmolding specifications.
  • second material overmolded onto the first material
  • a single portion of second material may be overmolded onto the first material such as to cover all areas of the ear protector 32 which are likely to cause an injury to the player due to sharper edges present therein.
  • the second material can be overmolded onto the first material as a single piece such as to cover both the internal peripheral edge 150 and the bottom edge 142 of the ear protector body 132.
  • any portion of the ear protector 32 may be covered by (or made of) the second material as to provide added comfort to the player's ears and to reduce the likelihood of injury thereto.
  • the overmolding of the second material onto the first material near the central aperture 48 of the ear protector 32 on the inner side 44 of the ear protector may extend to more than the internal peripheral edge 50 of the central aperture 48 of the ear protector 32 such that a substantial portion of the ear protector 32 that is adapted to generally face, receive or surround the player's ear is made of the second material overmolded onto the first material while the remaining of the ear protector 32 is made of the first material only.
  • Overmolding techniques provide a simple, cost-efficient and quick means of mass-producing the ear protector 32.
  • the ear protector 32 is produced in a dual-injection shell mold that includes two cavities.
  • a molding core closes with the first cavity and the first material of the ear protector 32 is injected into the mold.
  • the core ear protector body 132
  • the ear protector body 132 is then inserted into the second cavity and the second material is injected for overmolding where appropriate.
  • two cores are used such that both cavities can be used at the same time.
  • the two cavities are in one wall and the two cores are mounted on a platform in a way that they can both be inserted into the cavities at the same time.
  • the first cavity/core combination is molding the first material
  • the second cavity/core is overmolding the second material on a previously-molded layer of first material.
  • the completed outer shell the one that had been undergoing the overmolding step
  • the platform pivots such that the other, semi-completed, shell inserts into the second cavity.
  • the first cavity receives the now-empty core.
  • the first and second materials are selected based on a number of factors. For the first material, characteristics determining its ability to protect the player's ear from impact may be of interest. For the second material, one concern may be the physical feel of the material. Many other characteristics such as flexibility, tensile strength, hardness, density and cost may be considered in selecting the first and second materials.
  • the materials are also selected based on their suitability for overmolding.
  • the materials may be selected for their ability to adhere to one another.
  • the second material has a higher melting point such that it slightly melts the surface of the first material during overmolding. It is understood that the second material must have a melting point equal or higher.
  • the melting points of the first and second materials will be similar and in a non-limiting embodiment, the melting points of the respective materials are within 75°C of each other.
  • the two materials are selected from the same family as materials from the same family tend to be more compatible.
  • the ear protector 32 may be used for an adjustable helmet where the player can expand or contract the size of the helmet 10 by pushing or pulling the front and rear shells 12, 14 in relation to each other.
  • the ear protector 32 is thus affixed to the front shell 12 via affixing means passing through the apertures 47 and movement of the rear shell 14 relative to the rear extension 41 is allowed by the longitudinal slot 43. Because the rear extension 41 must be mounted between the rear shell 14 and inner rear pads 18, 20, the use of a first material that allows reducing the thickness of the rear extension 41 will allow to reduce the overall thickness of the helmet sides or to increase the thickness of the padding protection.
  • the thickness of the rear extension 41 may be about 1.5mm. If SURLYN TM is used for the first material, the thickness of the rear extension 41 may be about 2.5mm.
