The present invention relates to an attachment assembly for mounting a facemask to a sports helmet in such a way that the facemask will absorb and/or dissipate a very high percentage of impact energy from a ball or other oncoming force.
BACKGROUND OF THE INVENTIONHelmets are used in a wide range of sports. Helmets generally serve the same purpose in each sport, which is to protect the wearer's head from injury by providing a buffer zone between the wearer's head and an oncoming ball, puck, club, or other moving object.
Helmets worn by umpires and catchers in baseball or softball, football players, hockey players, and lacrosse players are well known and typically include a shell having inner and outer surfaces and a padding assembly connected to the inner surface of the shell. Many sport helmets also typically include corresponding facemasks mounted to the helmet. However, conventional facemask mountings provide little, if any, shock absorption. More particularly, when a moving object strikes the facemask, the force is typically transferred directly to the helmet with very little buffering or dampening. The current design of catcher's helmets, for example, transfers a very high percentage of impact energy from the ball directly to the wearer's head. This problem is also present in umpire masks and other helmets that include facemasks.
Neither the design of conventional facemask mounts nor the materials used in conventional facemask mounts provide much impact absorption. It would thus be desirable to provide a facemask that is mounted to a helmet such that the facemask can absorb and/or dissipate an increased percentage of impact energy from an oncoming ball, puck, club, or other moving object.
SUMMARY OF THE INVENTIONThe present invention presents a shock-absorbing facemask attachment assembly that provides absorption and dissipation of a high percentage of impact energy from an oncoming object. This shock absorption and dissipation is achieved through a mounting configuration and/or mounting materials that allow the facemask to greatly increase the impact absorption and to distribute a large amount of impact energy.
In one embodiment, the shock-absorbing facemask attachment assembly includes a housing attached to a helmet shell with an insert positioned in the housing, modeled after a hydraulic piston. The insert has a first end coupled to a facemask and a second end disposed in the housing. The insert is adapted to extend the second end further into the housing in response to a force applied to the first end. At least a portion of the insert may include an elastomer. Similarly, at least a portion of the housing may include an elastomer. The housing may include a compressible fluid or gel positioned between a distal surface of the second end of the insert and a bottom surface of the housing, such that the fluid or gel is compressed when a force is exerted on the facemask.
In another embodiment, the shock-absorbing facemask attachment assembly includes a housing attached to a helmet shell with a spring positioned in the housing. The spring has a first end coupled to a facemask and a second end disposed in the housing. The spring is adapted to be compressed further toward the housing in response to a force applied to the first end. One or more fasteners may be used to mount the spring to the facemask and/or to the housing. One or more of the fasteners may include nylon for greater flexibility. A compressible intermediate member may be positioned within the spring.
A bar of the facemask may be coupled to the first end of the spring, with the bar substantially perpendicular to the spring. A cover may be positioned over the portion of the facemask coupled to the first end of the spring. Additionally, a first bar of the facemask may be coupled to the first end of the spring while a second bar may be coupled to the cover.
More than just one spring may be included in each mounting assembly. For example, at least two springs, or at least three springs, may be coupled to each housing and the facemask. When multiple springs are present in a mounting assembly, the springs may be substantially parallel to one another.
In yet another embodiment, the shock-absorbing facemask attachment assembly includes a spring assembly in which a first spring has a first end coupled to a helmet shell and a second end coupled to a housing, and a second spring has a first end coupled to a facemask and a second end coupled to the housing. A third spring may also have a first end coupled to the facemask and a second end coupled to the housing. The springs may be substantially perpendicular to the helmet shell. Any or all of the springs may be coupled to the helmet shell, housing, or facemask with one or more fasteners. Any of the fasteners may include nylon for enhanced flexibility.
Any of the facemask mounting assemblies described herein may be attached to opposing sides of the helmet shell along opposite edges of a face opening portion of the helmet. In certain embodiments, one or more of the mounting assemblies may be attached to each side of the helmet shell. Alternatively or additionally, one or more of the mounting assemblies may be attached to the helmet shell in a central region above a face opening in the helmet. To highlight the shock-absorbing mechanism of the facemask attachment assembly, the housing and/or any cover portion may be transparent.
Any of the shock-absorbing facemask attachment assembly embodiments described herein may be applied to catcher's masks, umpire's masks, lacrosse helmets, football helmets, hockey helmets, and any other helmet that includes a facemask. Regardless of the type of helmet, shock-absorption is greatly improved by using any of the mounting schemes in this invention.
