Definitions

  • the present invention relates in general to safety helmets and more particularly to helmets for cyclists and in-line skaters.
  • Various different types of safety helmets have been designed for sporting activities where participants are apt to encounter collisions with objects and other participants. In many of these sporting activities, the participants are apt to be exercising strenuously whereby they perspire, especially on the tops of their heads.
  • sporting helmets are provided with spaces inside the helmet and vents to allow heat to radiate from the head of the wearer and air to flow through the helmet especially in moving sporting activities such as cycling and in-line skating. As more and more vents are placed in the helmet, the strength and structural integrity of the helmet is reduced thereby reducing the safety factor provided to the wearer.
  • the present invention is directed to a helmet construction including an inner, heavily vented, integrally molded core or liner constructed of a material that need not be strong enough to withstand the direct blows that are to be protected against by a safety helmet and an outer shell that fits over the core member with minimum vents such as in the front, back and top thereof, which with the core defines multiple continuous channels from the front to the back of the helmet for permitting maximum ventilation through the helmet while retaining strength and rigidity sufficient to withstand heavy blows to the helmet.
  • the inner core is formed of continuous ribs extending from the front to the back of the helmet with the top and bottom surfaces of the ribs rounded to minimize the contact between the ribs and both the head of the wearer and the outer shell.
  • Fig. 1 is a perspective view of a safety helmet in accordance with the present invention.
  • Fig. 2 is an exploded view of the inner core and shell of the safety helmet shown in Fig. 1.
  • Fig. 3 is a side elevational view of the safety helmet shown in Fig. 1 , the opposite side elevational view being a substantial mirror image thereof.
  • Fig. 4 is a bottom view of the helmet of Fig. 3.
  • Fig. 5 is a cross-sectional view of the helmet of Fig. 3, taken along line 5-5 in the direction of the arrows.
  • Fig. 6 is an enlarged view of that portion of the structure shown in Fig. 5 surrounded by the line 6-6.
  • Fig. 7 is a view similar to Fig. 3 of an alternative embodiment with the outer shell partially broken away to illustrate the air flow through the helmet.
  • Fig. 8 is a top view of the preferred embodiment of the present invention with the front of the helmet on the right.
  • Fig. 8A is an enlarged cross-sectional view of a portion of the structure shown in Fig. 8 at the front of the helmet taken along line AA in the direction of the arrows.
  • Fig. 8B is an enlarged view of a portion of the structure shown in Fig. 8 at the back of the helmet taken along line BB in the direction of the arrows.
  • Fig. 8C is a view similar to Fig. 6, but showing a cross- sectional view taken through the cross arch 50' extending between ribs of the core 10.
  • Fig. 9 is a sectional view of the helmet of Fig. 8 taken along line 9-9 in the direction of the arrows.
  • Fig. 10 is a front view of the helmet of Fig. 8.
  • Fig. 11 is a back view of the helmet of Fig. 8.
  • Fig. 12 is an elevational sectional view of the helmet shown in Fig. 8 taken along line 12-12 in the direction of the arrows.
  • Fig. 13 is an enlarged view of a portion of the structure shown in Fig. 9 delineated by line 13-13.
  • Fig. 14 is an enlarged view of the upper end of the stabilizing device shown in Fig 9 but separated from the helmet and with the cap member slightly displaced laterally from its attaching position.
  • While the present invention can take a number of different forms applicable to safety helmets designed specifically for certain sporting activities, the preferred embodiment is designed for cycling, in- line skating and auto and motorcycle racing and will be described with reference thereto.
  • the safety helmet A in accordance with the present invention includes an inner, heavily vented, integrally molded core or liner 10 and an outer shell member 70.
  • the core member 10 includes a lower support ring or oval 12 having front and back portions 14 and 16 and right and left side portions 18 and 20.
  • the lower support ring 12 has a flat top surface portion 22 extending around the helmet and on which the shell 70 is positioned. While the flat top surface 22 can lie in one plane for appearance purposes, it preferably follows an undulating contour including a depression 24 substantially in the middle of the front half of the core 10.
  • a lower semi-cylindrical guard ring 28 extends rearwardly, substantially horizontally below the upwardly rearwardly inclined portion 26 of the ring 12.
  • a plurality of spaced apart ribs 40 extend upwardly in arches 42 from the front of the support ring 12 to a high point about half way toward the back 16 of the ring 12 and then follow slightly downwardly curved sections 44. As shown in Figs. 5 and 6, the ribs 40 have rounded lower surfaces 46a and upper surfaces 46b which follow the contour of the inside surface of the shell 70. Alternatively, the upper surface shown as 46b' can be rounded to increase the open space for air flow through the helmet.
  • the ribs 40 which are typically spaced on the order of 3/8 of an inch provide elongate, substantially unobstructed channels 48 from the front 14 to the back of the core 16 for free flow of ventilation from the front to the back of the helmet.
  • the core includes at least one cross-arch 50 extending from side 18 to side 20 of the ring 12 and integrally connected to each of the ribs 40.
  • the cross-arch 50 has a vertical cross-sectional dimension 52 which is substantially less than the vertical cross-sectional dimension 54 of the ribs 40 to permit air to flow below the bottom of the cross-arch 50 over the wearer's head and above the top of the cross arch 50.
  • a reinforcing infrastructure can be included in the ring 12, ribs 40 and cross-rib 50 to provide additional strength, stability and lateral rigidity to the core 10 as disclosed in U.S. Patents 5,119,506 and 5,481 ,762.
  • the outer shell 70 which is typically formed of foam material stronger and more rigid then the material of the lower support ring 12 includes a lower flat surface 72 for intimate mating contact with a flat top surface portion 22 of the support ring 12 and an upwardly arched crown extending over the top of the inner core 10 in engaging contact with the top surface of the ribs 40.
  • the inner core 10 and the outer shell 70 are secured together by an adhesive bonding agent such as an epoxy adhesive like two part DP 100 manufactured by 3M.
  • the outer shell 70 has a front opening 76 in the form of a central substantially rectangular opening 76a and on opposite sides thereof two scoop shaped openings 76b and arched openings 78 at the back right and left sides.
  • the outer shell 70 includes an upwardly backwardly tapered opening 82 such that air flows not only into the helmet and over the wearer's head through the channels 48 and out the arched opening 78 and 80 at the back of the helmet but out through the tapered opening 82.
  • high velocity air over the top of the helmet helps to evacuate the air from inside the helmet through the top opening 82 and out the back openings 78 and 80.
  • the top surface of the ribs 40 can be angled upward to help direct air out the openings.
  • the wearer's head typically makes only narrow line contact with the lower curved surfaces of the ribs 40 thereby maximizing the surface of the wearer's head not in the contact with the helmet core 10 thereby permitting maximum radiation and evaporation of perspiration on the wearer's head. Heat will be able to radiate away from the wearer's head in a more direct path where it can be carried away by air flow between the bottom of the inner core 10 and the bottom surface of the shell 70. It has been discovered that this minimum line contact not only permits maximum radiation and evaporation of perspiration but at the same time holds the wearer's hair in place.
  • a helmet constructed in accordance with this invention distributes the structural foam more evenly throughout the helmet.
  • the structural material selected for the elements of the helmet can provide a strong and stable outside structural portion that can withstand high impacts with other obstacles without fracturing or breaking and at the same time provide a lower strength less expensive inner core.
  • the inner core 10 can be made of a resilient material to provide a more comfortable fit on the wearer's head.
  • the outside surface of the outer shell 70 can be provided with suitable decoration or can be provided with a thin outer layer which can be separately silk-screened and placed on the outer shell 70 as described in U.S. Pat. 4,993,082.
  • FIGs. 8-12 in which the reference numbers with a prime (“'") refer to similar elements as identified with unprimed numbers in the earlier figures, show the preferred embodiment of the invention and with additional openings in the top of the shell 70.
  • air flows into the helmet through the front opening 76' between the ribs 40'.
  • the ribs 40' At the front opening 76', the ribs 40' have forwardly projecting portions 41' on the top of which the outer shell 70' rests.
  • the ribs 40' have a rearward extension 41" on the top of which the outer shell 70' rests.
  • the outer shell 70' and the lower portion ring portion 12' of the inner core 10' have an outer layer or micro shell 98' and 99', respectively, covering such as of polycarbonate about 0.03 inch thick which can be [insert] molded when the outer shell 70' and the ring portion 12' are molded.
  • the outer shell 70' has three separate sets of openings 92', 94' and 96' located from the front to the back of the helmet, respectively, between the ribs. Underneath the central portion of the set of openings
  • the rear attaching straps (not shown) of the helmet are mounted.
  • the cross rib 50' extending between the individual ribs 40' has a lower surface upwardly curved from the sides of the ribs 40' and an upper surface that is in contact with the inside surface of the outer shell 70.
  • the inner core 10 is made of expanded polystyrene having a density of 4 to 6 lbs/ft 3 , preferably 5 Ibs/fr 3
  • the outer shell 70 is made of EPS having a density of 5 to 8 lbs/ft 3 , preferably 5.5 lbs/ft 3
  • the inner core 10 and the outer shell 70 can also be made of expanded polypropolene (EPP).
  • EPP expanded polypropolene
  • the inner core has seven ribs 40 each 3/8" in width and 1/2" in height with the channels 48 therebetween being 3/8" wide.
  • the helmet includes a sizing and stabilizing device 110 best illustrated in Figs. 9-14.
  • the stabilizing device 110 includes a stem 111 , the upper end of which is held in the helmet and the lower portion of which divides into a Y with lower extending portions 112, which are slidably, adjustably attached to buckle members 113.
  • the lower ends of the lower portions 112 have a slot 114 with a series of enlargements 114' to receive a pin member 115 (shown in phantom) inside of the buckle members 113 so that relative movement between the lower portions 112 of the stem and the pin 115 of the buckle members 113 along the length of the slot 114 will adjust the vertical distance from the buckle members 113 to the top of the stem 111 to fit different wearers' heads.
  • each of the buckle members 113 include a pair of parallel closely spaced apart slots 116, through which a strap 117 can be looped back on itself for forming an adjustable loop 117' using VELCRO ® hook and loop type fasteners and with the other end of the strap 117 attached such as by similar hook and loop type fasteners to a patch 118 on the inside of the sides of the helmet, typically with patch 118 located behind a removable cushion pad 119 which is shown in Fig. 12 and which engages the head of the wearer.
  • a connecting strap 121 extends between the two buckle members 113.
  • the straps 117 and/or 121 can be elastic or include elastic portions which help the stabilizing device 110 provide a close fit of the safety helmet A to the wearer's head.
  • the lower portions 112 of the stem 111 are curved in an arch both vertically and laterally going around behind the wearer's head so that the buckle members 113 and straps 117 and 120 extend around the occipital region of the wearer's head. Either or both of the straps 117 and
  • the 120 can be elastic or include elastic portions for resilient fitting of the stabilizing device 110 on the head of the wearer.
  • the helmet includes a cylindrical channel 122 with an enlarged diameter 122 at its upper end through the lower portion
  • the upper end 111' of the stem 111 of the stabilizing device 110 has a plurality of parallel protruding ribs 123.
