Abstract

A head covering or helmet pads are removably attached to the outer surface of an existing sport's helmet. The pads are constructed to conform to the contours of the outer surface of the helmet. The pads are made from layers of thermoplastic material structured to absorb both shock and acoustic waves that may cause concussive type injuries. The thermoplastic may be an open-cell foam material selected from the group consisting of neoprene, polyethylene, silicon, urethane, silicon/urethane blend.

Description

CROSS-REFERENCE TO RELATED APPLICATION
• This application is a continuation in part of U.S. utility application Ser. No. 13/854,893, filed Apr. 1, 2013, now U.S. Pat. No. 8,826,468, wherein such application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/638,922, filed Apr. 26, 2012.
BACKGROUND OF THE INVENTION
• 1. Field of the Invention
• The present invention generally relates to protective sportswear, and particularly to supplemental external helmet pads for a sports helmet.
• 2. Description of the Related Art
• Protecting athletes from disabling injury has long been a primary focus for practitioners in the field of sports medicine and manufacturers of protective sportswear. The prevention of concussion injuries has been especially a target of discussion in view of recent findings regarding the long-term effects of such injuries. Athletes participating in sports, such as football, hockey, cycling, baseball, etc., whether professional or amateur, typically are required to wear helmets for protection in violent collisions or blows to the head. Waves (shock and acoustic) propagated by the aforementioned collisions and blows are thought to cause stress to the brain that may consequently produce concussions. Heretofore, helmets have been designed to protect the athlete from the effects of shock waves. No attention has been given to the effect of acoustic waves as a causative factor in concussive injuries. The need for a protective system that could be applied to existing helmet structure and that would be effective to absorb both shock and acoustic waves would be accepted eagerly in the art. Thus, helmet pads solving the aforementioned problem are desired.
SUMMARY OF THE INVENTION
• The present invention is drawn to helmet pads that are removably attached to the outer surface of an existing helmet. The pads are constructed to conform to the contours of the outer surface of the helmet. The pads are structured to absorb both shock and acoustic waves. Each pad is constructed of layers of different thermoplastic foam materials, and includes layers designed to collapse to help absorb shock waves and acoustic waves that might otherwise produce head injuries resulting in stress to the brain.
• Accordingly, the invention presents protective pads that can be quickly and easily attached to the outer surface of a conventional sports helmet. The pads provide supplemental protection against impacts that may cause concussive type injuries. The invention provides for improved elements thereof in an arrangement for the purposes described that are inexpensive, dependable and fully effective in accomplishing their intended purposes.
• These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
• FIG. 1 is an environmental, perspective view of helmet pads according to the present invention.
• FIG. 2 is a partially exploded perspective view of helmet pads according to the present invention.
• FIG. 3 is an end view, in section, of a helmet pad according to the present invention.
• Similar reference characters denote corresponding features consistently throughout the attached drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
• Referring toFIGS. 1-3 of the drawings, thehelmet pads10 include a top pad11 and twoside pads13. The pads are adapted to be removably attached to theouter surfaces12 of aconventional sports helmet14. This arrangement permits the pads to be instantly adaptable to existing sport helmets without modification of the helmet structure. As indicated above, thepads10 are designed to conform to the contours of thehelmet14 and may be configured in various patterns to cover the entire exterior surface of thehelmet14. Although, as illustrated, thehelmet14 is generally of the type used in football, it should be recognized that thepads10 may be designed for any type (lacrosse, skating, cycling, etc.) of sports helmet. As presently contemplated, the pads will have a thickness ranging from 0.040 to 0.050 inches depending on the type of sport for which they are used.
• As best seen inFIG. 3, eachpad10 is encased in a shell or outer layer16 having abase16a. The shell is fabricated from a suitable material, such as a silicon closed cell sponge, that would permit the shell to be painted or designed with school or team logos and/or colors, if desired. Alternatively, the shell or outer layer16 may also be fabricated from other suitable materials of open cell construction, such as neoprene, polyethylene, silicon, urethane, silicon/urethane blend or the like. An example of a urethane open cell foam is PORON® or PORON® XRD®, an open cell urethane foam material produced by Rogers Corporation, Rogers, Conn. 06263. An outer layer of polypropylene or the like18 is positioned immediately below the shell16. First and second crumple zones are defined at20 and22. Thecrumple zones20 and22 are fabricated from polyvinyl chloride, or other suitable material that is extruded into a honeycombed configuration having alternating inverted V-shaped structures24 encapsulated therein, the vertex of the V-shaped structures being formed asthick fingers24aextending in opposite directions and thin,angled legs24b, joining each finger to the next. The thin legs are engineered to fracture or crumple upon impact exceeding a predetermined threshold of force. The V-shaped structures24 are fabricated from high-density polyethylene or the like, and are aligned against each other to create a folding zone when impacted. Thecrumple zones20 and22 create a stable platform that will absorb an impact equal to 250 lbs. of kinetic momentum before crumpling. Lesser impacts will produce no crumpling. A layer of high-density foam material26, e.g., polyurethane, is disposed below and adjacent to thecrumple zone22 to absorb acoustical shock waves and limit exposure thereof to the helmet.Reference character28 indicates an adhesive layer that is disposed along the exterior surface of the base of thepad10, whereby the pad may be easily attached to the surface of thehelmet14. Theadhesive layer28 may be covered with conventional, removable release paper (not shown) when thepad10 is not in use. It is further contemplated that the open cell materials, such as neoprene, polyethylene, silicon, urethane, silicon/urethane blend, may be used for any or all of the aforementioned polymers; that is, polypropylene, polyvinyl chloride, high-density polyethylene or closed cell silicon or urethane.
• 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.
