Definitions

  • Protective helmets are worn in many situations to protect the head from injury that can result from impact with a static or dynamic object. Such helmets are often worn by players of various sports. For example, baseball players typically wear helmets when they are batting to protect their head from the pitched baseball.
  • Fig. 1A is a top perspective view of a first embodiment of a faceted protective helmet.
  • Fig. 1 B is a front view of the protective helmet of Fig. 1A.
  • Fig. 2A is a top perspective view of a second embodiment of a faceted protective helmet.
  • Fig. 2B is a side view of the protective helmet of Fig. 2A.
  • Fig. 3A is a side view of a third embodiment of a faceted protective helmet.
  • Fig. 3B is a top perspective view of the protective helmet of Fig. 3A.
  • Fig. 4 is a schematic view of a syntactic material that can be used to form an outer shell of a protective helmet.
  • the helmets include faceted outer surfaces that reduce the potential for normal impacts and therefore dissipate energy that might otherwise be transmitted to the wearer's head.
  • Figs. 1A and 1 B illustrate a first embodiment of a protective helmet 10, which can be configured as a sports helmet.
  • the helmet 10 generally comprises an outer shell 12 that is sized and configured to surround a wearer's head from the base of the skull to the forehead and from one ear to the other.
  • the outer shell 12 is sized and configured to surround all but the wearer's face.
  • the helmet 10 can also include a relatively soft inner liner (not shown) that includes one or more flexible and/or resilient pads that provide cushioning to the head and dissipate energy from impacts.
  • the outer shell 12 is generally rigid and can be made of any material that provides impact protection to the wearer.
  • the shell 12 is made of a polymeric material that is approximately 1 to 4 mm thick. The polymeric material that is used can depend upon the application of the helmet and the level of protection that is required.
  • the shell 12 is made of a long fiber thermoplastic (LFT) material.
  • LFTs are desirable because they provide high levels of protection like continuous fiber reinforced composites but can be processed using traditional plastics molding equipment. Therefore, parts can be manufactured at medium- to high-volume rates with excellent consistency and repeatability.
  • Long fibers e.g., fiber lengths of about 3 mm to 50 mm
  • LFT materials are formed by hot melt-impregnating continuous reinforcing fiber into a thermoplastic resin.
  • the mixture can be cooled and formed (e.g., chopped) into discontinuous reinforcing fiber pellets.
  • the amount of thermoplastic resin can be approximately 50 to 99 weight % of the LFT material and the amount of continuous reinforcing fiber (and once cut into the discontinuous reinforcing fiber) can be approximately 0.1 to 50 weight % of the LFT material.
  • Example thermoplastic resins include polyamide, acrylonitrile butadiene styrene (ABS), polyphenylene sulfide, polypropylene, poly ether ether ketone, poly ether ketone, polyethylene, poly butylene terephthalate, poly ethylene terephthalate, polyoxymethylene, and combinations (mixtures) thereof.
  • Example reinforcing fibers include carbon, glass, aramid, polypropylene, polyethylene, basalt, poly ⁇ diimidazo pyridinylene (dihydroxy) phenylene ⁇ , natural fibers such as flax, kenaf, bamboo, jute, sisal, and combinations (mixtures) thereof.
  • the outer shell 12 is made of a non-reinforced polymer material.
  • a non-reinforced polymer material examples include polyamide, ABS, polyphenylene sulfide, polypropylene, poly ether ether ketone, poly ether ketone, polyethylene, poly butylene terephthalate, poly ethylene terephthalate, polyoxymethylene, or combinations (mixtures) thereof.
  • the outer shell 12 is made of a syntactic material that comprises a plurality of microspheres (also referred to as cenospheres or microballoons) that are compounded with a thermoplastic resin.
  • a syntactic material 90 that comprises microspheres 92 compounded with a resin 94.
  • the microspheres 92 are small, hollow spherical elements having an interior void 96 that is enclosed by a thin outer shell 98. Because much of the volume of the microspheres 92 is void space (e.g., air), the microspheres and the syntactic material 90 are very lightweight.
  • the syntactic material 90 has a density of approximately 0.3 to 0.9 g/cc and the microspheres 92 comprise approximately 30% to 35% of the material by volume percentage.
  • the microspheres 92 have a nominal outer diameter of approximately 0.1 mm to 1 .0 mm and the shells 98 have a thickness of approximately 20 ⁇ to 200 ⁇ .
  • the microsphere shells 98 can be made of substantially any material that can be formed (e.g., blown) into a very small hollow sphere.
  • the microsphere's shells 98 can be made of a polymeric, ceramic, glass, or metal material.
  • the resin 94 can comprise a polymeric resin.
  • the resin is a thermoplastic resin comprising an olefin, such as polypropylene, polyethylene, or combinations (mixtures) thereof.
  • the thermoplastic resin can comprise an engineered polymer, such as polyamide, polyether ether ketone (PEEK), polyether ketone (PEK), polyethyleneimine (PEI), polyphenylene sulfide (PPS), or combinations (mixtures) thereof.
  • the protective helmet 10 can be used in substantially any context.
  • the helmet 10 is used to protect the wearer's head during sports activities.
  • the helmet 10 takes the form of a baseball batting helmet that includes one or more ear flaps 14 and a sun visor 16.
  • the helmet 10 could be configured for use in other sports, including football, hockey, lacrosse, field hockey, polo, bicycling, motorsports, and the like.
  • the helmet 10 could be configured for non-sports applications, including military and combat applications.
  • the outer surface 18 of the shell 12 comprises a plurality of facets 20 that lie in non-parallel planes.
  • the facets 20 are generally planar (i.e., not curved) and reduce the likelihood that a projectile will impact the shell 12 from a normal (perpendicular) direction. Accordingly, such projectiles will have the tendency to skirt or skip across the surface 18 of the shell 12.
  • each facet 20 defines a similar geometric shape.
  • each facet 20 is triangular and therefore includes three linear sides. In such cases, the triangles can have three equal angles (equilateral triangle), two equal angles (isosceles triangle), or no equal angles (scalene triangle).
  • the groups of facets 20 define multifaceted prisms on the surface 18 of the shell 12, such as the hexagonal, six-facet prism 22 highlighted in Fig. 1A and/or the pentagonal five-facet prism 24 highlighted in Fig. 1 B.
  • the prism 22, 24 defines a raised central point 26 that is formed by the corners of the facets 20 that define the prism.
  • each facet 20 has a nominal dimension of approximately 1 to 3 inches. In the example embodiment of Figs. 1 A and 1 B, in which the facets 20 are triangular, this dimension can be the length of one or more sides of the triangles. In other embodiments, in which the facets are not triangular, the nominal dimension can be a maximum dimension (length or width) of the facet.
  • the outer surface 18 of the shell 12 can comprise approximately 80 to 150 facets 20.
  • the facets 20 can extend across much of the outer surface 18 of the shell 12 but not all of it. In the embodiment of these figures, the facets 20 do not extend to the ear flaps 14 or the sun visor 16.
  • the outer shell 12 also includes ventilation openings 28 that enable air to reach the head and heat and vapor to escape the helmet 10.
  • the openings 28 are configured as elongated linear slits that extend along the length of the sides (edges) of two or more facets 20.
  • the shell 12 includes four such openings 28 arranged in a spaced configuration near the top of the shell.
  • the outer shell 12 also includes ear openings 30 that are formed in the ear flaps 14.
  • the ear openings 30 have a general teardrop shape in which at least one edge of the openings 30 is curved.
  • Figs. 2A and 2B illustrate a further embodiment of a protective helmet 40.
  • the helmet 40 is similar in many ways to the helmet 10 shown in Figs. 1A and 1 B. Therefore, the helmet 40 generally comprises an outer shell 42 that can be made of one of the materials described above in relation to the outer shell 12.
  • the outer shell 42 includes ear flaps 44 and a sun visor 46 and comprises an outer surface 48 that has a plurality of facets 50 that define multifaceted prisms 52 that each includes a raised central point 54 formed by the corners of the facets.
  • the outer shell 42 further includes ventilation openings 56 and ear openings 58.
  • the outer shell 40 includes facets 50 that extend across the ear flaps 44.
  • the ear openings 58 are triangular instead of being teardrop shaped.
  • Figs. 3A and 3B illustrate yet another embodiment of a protective helmet 60.
  • the helmet 50 is similar in many ways to the helmet 40 shown in Figs. 2A and 2B. Therefore, the helmet 60 generally comprises an outer shell 62 that can be made of one of the materials described above in relation to the outer shell 12.
  • the outer shell 62 includes ear flaps 64 and a sun visor 66 and comprises an outer surface 68 that has a plurality of facets 70 that define multifaceted prisms 72 that each includes a raised central point 74 formed by the corners of the facets.
  • the outer shell 62 further includes ventilation openings 76.
  • openings 76 of the helmet 60 are arranged in an alternative pattern in which six ventilation openings 28 are arranged in an "X" pattern that is visible from the top and rear of the helmet (see Fig. 3B).
  • the "X" pattern is formed by two crossed lines of openings 28, with each opening being arranged with its longitudinal axis aligned with its line.
  • the helmet 60 includes facets 70 that extend across the sun visor 66.
  • the helmet 60 has an alternative ear opening pattern in which each ear flap 44 includes a first or primary ear opening 78 and a second or secondary ear opening 80.
  • the first ear opening 78 is larger than the secondary ear opening 80.
  • the primary ear opening 78 is triangular while the secondary ear opening is elongated and linear.
  • the inner surface of the outer shell 12 can either be faceted in a similar manner to the outer surface 18 or can be smooth similar to conventional helmets. Regardless, it is reiterated that a relatively soft inner liner comprising one or more flexible and/or resilient pads can be provided within the shell to cushion the wearer's head and/or dissipate direct or rotational force.
