Definitions

  • the present invention relates to headgear having a faceguard that is provided with shock-absorbing means, and to a shock absorber suitable for use as the shock-absorbing means.
  • the protective headgear is simply a rigid facemask with cushioning padding on the outer frame that is held against the area around the wearer's face.
  • the traditional headgear do mitigate the effect of impacts to the head and neck to some extent, they do not reduce the risk of head or neck injury to the desired degree.
  • protective headgear having shock-absorbing elements between the faceguard portion and the head-engaging portion of the headgear have been proposed in the prior art to further reduce the risk of injury.
  • none of the prior art headgear with shock-absorbing faceguards have been widely adopted. The need remains for a shock absorber for use with the faceguard of headgear that is robust enough, compact enough, unobtrusive enough, and adaptable enough for large scale adoption.
  • the present invention is directed to a shock absorber and a headgear that employs the shock absorber.
  • the headgear includes a faceguard and a head-engaging member.
  • the shock absorber supports the protective faceguard relative to the head-engaging member.
  • the shock absorber includes a support structure, a guide rod, a sliding member, and a resilient member.
  • the support structure is adapted for rigid attachment to either the head-engaging member or the faceguard.
  • the guide rod is supported by the support structure in a fixed position relative to the support structure.
  • the guide rod has first and second end portions, a length, and a longitudinal axis. The guide rod is supported by the support structure near the end portions of the guide rod.
  • the sliding member is guided by the guide rod for rectilinear movement in a direction parallel to the longitudinal axis of the guide rod.
  • the movement of the sliding member is confined between the ends of the guide rod.
  • the sliding member is adapted for rigid attachment to either the head engaging-member or the faceguard depending upon which of these is the one to which the support structure is attached.
  • the resilient member acts on the sliding member to bias the sliding member toward one end of the guide rod.
  • the resilient member is a coil spring that is provided on the guide rod between the sliding member and the second end portion of the guide rod and biases the sliding member toward the first end portion of the guide rod.
  • the support structure is attached to the head-engaging member and the sliding member is attached to the faceguard.
  • the sliding member When an object impacts the faceguard, the sliding member is pushed from one end of the guide rod toward the other end resulting in the compression of the coil spring.
  • the resilient member in this case the coil spring, can absorb at least a portion of the impact energy of the object and cushion the blow to the faceguard.
  • the headgear of the present invention includes a head-engaging portion and a faceguard.
  • the head-engaging portion is made of first and second enclosed frames.
  • the first frame is larger and designed to surround the wearer's face.

  • the second frame surrounds the wearer's face and appears roughly concentric with the first frame when viewed from the front in relation to the wearer's face.
  • the second frame is spaced apart from the first frame such that it is farther from the wearer's face as compared to the first frame.
  • the second frame is connected to the first frame by pairs of L-shaped bars. Each pair of L-shaped bars supports a shock absorber in a protected location between the first and second frames of the head-engaging portion.
  • the faceguard includes an enclosed frame that surrounds the wearer's face when viewed from the front in relation to the wearer's face.
  • the frame of the faceguard is larger than the second frame of the head-engaging portion and envelops the second frame of the head-engaging portion when viewed from the front in relation to the wearer's face.
  • the faceguard includes a first plurality of bars that are substantially parallel to the sagittal plane of the wearer's body and a second plurality of bars that are parallel to the transverse plane of the wearer's body. These pluralities of bars are attached to the frame of the faceguard such that they are positioned in front of the wearer's face and can thus provide protection to the wearer's face. The pluralities of bars are positioned to provide complete protection to the entire frontal area of the wearer's head.
  • the frame of the faceguard is attached to the plurality of shock absorbers.
  • the support structure of shock absorber is rigidly attached to a corresponding pair of the L-shaped bars while the sliding member is rigidly attached to the frame of the faceguard.
  • the shock absorber or the headgear could be configured such that the sliding member is attached to the head-engaging portion and the support structure of the shock absorber is attached to the faceguard.
  • the attachments between the shock absorber and the head-engaging portion or the attachment between the shock absorber and the faceguard or both could be made flexible instead of rigid as long as the attachment means used is resilient and strong enough to withstand the punishment it would be expected to receive.

  • (1) Field of the Invention
  • The present invention relates to headgear having a faceguard that is provided with shock-absorbing means, and to a shock absorber suitable for use as the shock-absorbing means.
  • (2) Description of Related Art, Including Information Disclosed Under 37 C.F.R. Sections 1.97 and 1.98
  • The health effects of concussions, including repeated minor concussions, suffered by athletes engaged in sports where there is a substantial risk of severe impacts to the athlete's head and face have become a major concern to the athletes, sports teams, governing bodies of sports leagues, and the public in recent years. Impacts to the head may also cause neck injuries that are sometimes severe enough to cause the athlete to become paralyzed. This is particularly a concern with impacts directed frontally toward the face. Athletes in such sports have traditionally worn protective headgear in the form of a hard helmet with a facemask rigidly attached to the helmet. Soft cushioning pads are provided inside the helmet around the wearer's head excluding the facial area. In some other sports, for example baseball, the protective headgear is simply a rigid facemask with cushioning padding on the outer frame that is held against the area around the wearer's face. Although the traditional headgear do mitigate the effect of impacts to the head and neck to some extent, they do not reduce the risk of head or neck injury to the desired degree. Accordingly, protective headgear having shock-absorbing elements between the faceguard portion and the head-engaging portion of the headgear have been proposed in the prior art to further reduce the risk of injury. However, none of the prior art headgear with shock-absorbing faceguards have been widely adopted. The need remains for a shock absorber for use with the faceguard of headgear that is robust enough, compact enough, unobtrusive enough, and adaptable enough for large scale adoption. The need also remains for headgear that can effectively incorporate such a shock absorber. There is also a need for headgear that will keep the shock absorber well protected. None of the prior art headgear are seen to teach or suggest the unique features of the present invention or to achieve the advantages of the present invention that will become apparent from the description and drawings that follow.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
  • The present invention is directed to a shock absorber and a headgear that employs the shock absorber. The headgear includes a faceguard and a head-engaging member. The shock absorber supports the protective faceguard relative to the head-engaging member. The shock absorber includes a support structure, a guide rod, a sliding member, and a resilient member. The support structure is adapted for rigid attachment to either the head-engaging member or the faceguard. The guide rod is supported by the support structure in a fixed position relative to the support structure. The guide rod has first and second end portions, a length, and a longitudinal axis. The guide rod is supported by the support structure near the end portions of the guide rod. The sliding member is guided by the guide rod for rectilinear movement in a direction parallel to the longitudinal axis of the guide rod. The movement of the sliding member is confined between the ends of the guide rod. The sliding member is adapted for rigid attachment to either the head engaging-member or the faceguard depending upon which of these is the one to which the support structure is attached. The resilient member acts on the sliding member to bias the sliding member toward one end of the guide rod. In the illustrated example, the resilient member is a coil spring that is provided on the guide rod between the sliding member and the second end portion of the guide rod and biases the sliding member toward the first end portion of the guide rod. In the illustrated example, the support structure is attached to the head-engaging member and the sliding member is attached to the faceguard. When an object impacts the faceguard, the sliding member is pushed from one end of the guide rod toward the other end resulting in the compression of the coil spring. Thus, the resilient member, in this case the coil spring, can absorb at least a portion of the impact energy of the object and cushion the blow to the faceguard.
  • The headgear of the present invention includes a head-engaging portion and a faceguard. The head-engaging portion is made of first and second enclosed frames. The first frame is larger and designed to surround the wearer's face. The first frame is the closest to the wearer's face. The second frame surrounds the wearer's face and appears roughly concentric with the first frame when viewed from the front in relation to the wearer's face. The second frame is spaced apart from the first frame such that it is farther from the wearer's face as compared to the first frame. The second frame is connected to the first frame by pairs of L-shaped bars. Each pair of L-shaped bars supports a shock absorber in a protected location between the first and second frames of the head-engaging portion. The faceguard includes an enclosed frame that surrounds the wearer's face when viewed from the front in relation to the wearer's face. The frame of the faceguard is larger than the second frame of the head-engaging portion and envelops the second frame of the head-engaging portion when viewed from the front in relation to the wearer's face. The faceguard includes a first plurality of bars that are substantially parallel to the sagittal plane of the wearer's body and a second plurality of bars that are parallel to the transverse plane of the wearer's body. These pluralities of bars are attached to the frame of the faceguard such that they are positioned in front of the wearer's face and can thus provide protection to the wearer's face. The pluralities of bars are positioned to provide complete protection to the entire frontal area of the wearer's head. The frame of the faceguard is attached to the plurality of shock absorbers.
  • In the illustrated embodiment, the support structure of shock absorber is rigidly attached to a corresponding pair of the L-shaped bars while the sliding member is rigidly attached to the frame of the faceguard. The shock absorber or the headgear could be configured such that the sliding member is attached to the head-engaging portion and the support structure of the shock absorber is attached to the faceguard. Also, the attachments between the shock absorber and the head-engaging portion or the attachment between the shock absorber and the faceguard or both could be made flexible instead of rigid as long as the attachment means used is resilient and strong enough to withstand the punishment it would be expected to receive.
  • Accordingly, it is an object of the invention to provide a shock absorber for a faceguard that has a sliding member that does not extend beyond the support structure of the shock absorber so that the sliding member is not in a vulnerable position.
  • It is another object of the invention to provide a shock absorber for a faceguard that is robust.
  • It is yet another object of the invention to provide a shock absorber for a faceguard that is compact.
  • It is yet another object of the invention to provide a shock absorber for a faceguard that is unobtrusive.
  • It is yet another object of the invention to provide a shock absorber for a faceguard that is adaptable to a wide variety of applications.
  • It is yet another object of the invention to provide a headgear that provides a protected mounting location for mounting a shock absorber for a faceguard.
  • These and other objects of the present invention will become apparent from the description below and the drawings.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
  • Referring to FIGS. 1-9, the present invention is directed to a shock absorber 100 and headgear 200 that employs a shock absorber such as, for example, the shock absorber 100. The headgear 200 includes a faceguard 202 and a head-engaging member 204. The shock absorber 100 supports the protective faceguard 202 relative to the head-engaging member 204. The shock absorber 100 includes a support structure 102, a guide rod 122 or 132, a sliding member 142, and a resilient member 152. The support structure 102 is adapted for rigid attachment to either the head-engaging member 204 or the faceguard 202. The guide rod 122 or 132 is supported by the support structure 102 in a fixed position relative to the support structure 102. The guide rod 122, 132 has first and second end portions, a length, and a longitudinal axis. The guide rod 122, 132 is supported by the support structure 102 near the end portions of the guide rod. The sliding member 142 is guided by the guide rod 122, 132 for rectilinear movement in a direction parallel to the longitudinal axis of the guide rod. The movement of the sliding member 142 is confined between the ends of the guide rod 122, 132. The sliding member 142 is adapted for rigid attachment to either the head-engaging member 204 or the faceguard 202 depending upon which of these is the one to which the support structure is attached. The resilient member 152 acts on the sliding member 142 to bias the sliding member toward one end of the guide rod 122, 132. In the illustrated example, the resilient member is a coil spring 154 or 156 that is provided on the guide rod 122, 132 between the sliding member 142 and the second end portion of the guide rod and biases the sliding member 142 toward the first end portion of the guide rod 122, 132. In the illustrated example, the support structure 102 is attached to the head-engaging member 204 and the sliding member is attached to the faceguard 202. When an object impacts the faceguard 202, the sliding member 142 is pushed from one end of the guide rod 122, 132 toward the other end resulting in the compression of the coil spring 154, 156. Thus, the resilient member 152, in this case the coil spring 154, 156, can absorb at least a portion of the impact energy of the object and cushion the blow to the faceguard 202. The movement of the sliding member 142 is limited to a portion of the length of the guide rod 122, 132. The movement of the sliding member 142 is limited to rectilinear motion in a direction parallel to the longitudinal axis of the guide rod 122, 132.
  • The headgear 200 of the present invention includes a head-engaging portion 204 and a faceguard 202. The head-engaging portion 204 is made of first and second substantially enclosed frames 206 and 208, respectively. The first frame 206 is larger than the second frame 208 and is designed to surround the wearer's face. The first frame 206 is the closest to the wearer's face. The second frame 208 surrounds the wearer's face and appears roughly concentric with the first frame 206 when viewed from the front in relation to the wearer's face. The second frame 208 is spaced apart from the first frame 206 such that it is farther from the wearer's face as compared to the first frame. The second frame 208 is connected to the first frame 206 by pairs of L-shaped bars 210. Each pair of L-shaped bars 210 supports a shock absorber 100 in a protected location between the first and second frames of the head-engaging portion 204. The faceguard 202 includes a substantially enclosed frame 212 that surrounds the wearer's face when viewed from the front in relation to the wearer's face. The frame 212 of the faceguard 202 is larger than the second frame 208 of the head-engaging portion 204 and envelops the second frame 208 of the head-engaging portion 204 when viewed from the front in relation to the wearer's face. The faceguard 202 includes a first plurality of bars 214 that are substantially parallel to the sagittal plane of the wearer's body and a second plurality of bars 216 that are parallel to the transverse plane of the wearer's body. These pluralities of bars 214, 216 are attached to the frame 212 of the faceguard 202 such that they are positioned in front of the wearer's face and can thus provide protection to the wearer's face. The pluralities of bars 214, 216 are positioned to provide complete protection to the entire frontal area of the wearer's head. The frame 212 of the faceguard 202 is attached to the plurality of shock absorbers 100.
  • In the illustrated embodiment, the support structure 102 of shock absorber 100 is rigidly attached to a corresponding pair of the L-shaped bars 210 while the sliding member 142 is rigidly attached to the frame 212 of the faceguard 202.

One or both of the guide rods 122 and 132 could be configured to provide a second shoulder or flange (not shown) near their second end portions 126, 136 such that the second ends 157 and 161 of the springs 154 and 156 bear against that second shoulder or flange rather than against the second endplate 108. Thus, the second ends 157 and 161 of the springs 154 and 156 may bear indirectly against the support structure 102.
  • In the illustrated embodiment, a plurality of tabs 218 are provided on the frame 212 of the faceguard 202. Each of the tabs 218 has a hole 220 that is engaged by a respective fastener 150 to secure the sliding member 142 of a respective shock absorber 100 to the faceguard 202. The first plurality of bars 214 may also be attached to one or more of the second plurality of bars 216. It is also possible to make the tabs 218 integral with the sliding member 142, while using a fastener 150 to secure the sliding member 142 to the frame 212 or any of the pluralities of bars 214, 216. The head-engaging member 204 is provided with padding (not shown) for engagement with the wearer's head.
  • In the illustrated embodiment, first and second tubular sleeves 219 and 222 are provided at the openings 144 and 146, respectively, to give a greater bearing surface between the sliding member 142 and the guide rods 122 and 132 so as to reduce tilting of the sliding member relative to the guide rods, thus reducing the possibility of the sliding member 142 jamming on the guide rods. The first and second tubular sleeves 219 and 222 are in engagement with the openings 144 and 146, respectively. The first and second tubular sleeves 219 and 222 are identical to simplify manufacture. Each of the first and second tubular sleeves 219 and 222 has a first portion 224, 226, respectively, and a second portion 228, 230, respectively. Each of the first and second tubular sleeves 219 and 222 has an annular flange 232, 234, respectively, located intermediate its first portion 224, 226 and its second portion 228, 230. The guide rod 122 extends through the first sleeve 219, and the guide rod 132 extends through the second sleeve 222.
  • The first portion 224 of the first sleeve 219 fits into the opening 144 of the sliding member 142 with the flange 232 of the sleeve 219 abutting the sliding member 142. The second portion 228 of the first sleeve 219 fits into the space between the coils of the spring 154 and the portion of the guide rod 122 that is of the second diameter. The first end 155 of the coil spring engages the flange 232 of the sleeve 219 to bias the sliding member 142 toward the first end portion 124 of the guide rod 122. Thus, the spring 154 indirectly bears against the sliding member 142.
  • The first portion 226 of the second sleeve 222 fits into the opening 146 of the sliding member 142 with the flange 234 of the sleeve 222 abutting the sliding member 142. The second portion 230 of the second sleeve 222 fits into the space between the coils of the spring 156 and the portion of the guide rod 132 that is of the second diameter. The first end 159 of the coil spring 156 engages the flange 234 of the sleeve 222 to bias the sliding member 142 toward the first end portion 134 of the guide rod 132. Thus, the spring 156 indirectly bears against the sliding member 142.
  • The illustrated headgear is particularly suited for use by a baseball catcher or umpire. In use, the headgear 200 is secured to the wearer's head using straps (not shown) or the like in the conventional manner. Padding (not shown) is provided between the wearer's head and the head-engaging portion 204. The padding and straps must be applied in such a way so as to not interfere with the relative movement between the head-engaging portion 204 and the faceguard 202. Normally, the springs 154, 156 of the shock absorber 100 will bias the sliding member 142 into contact with the first endplate 106. When an object impacts the faceguard 202, the sliding member 142 is pushed toward the endplate 108, which causes the springs 154, 156 to be compressed between the sliding member 142 and the endplate 108. Thus, the springs 154, 156 absorb at least a portion of the impact energy of the object rather than transmitting it to the wearer's head.
  • It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
