1. Field of the Invention
The present invention relates to protective sports equipment, and more particularly to protective batting helmets used in baseball and softball.
2. Description of Related Art
Protective helmets are commonly used in various sports to provide protection to a player's head. In baseball, for example, players commonly wear batting helmets to provide protection against wild pitches or foul balls. Offensive players also sometimes wear batting helmets when running the bases to protect against injury from hit or thrown balls.
In lower-level leagues, especially those geared to younger players, protective batting helmets are required to be worn by offensive players whenever they are at-bat or on base. Typically, batting helmets include an inner foam core configured to fit on and protect the wearer's head, with an outer protective shell covering the foam core, with the shell extending further downwardly from the inner core, towards the wearer's neck and shoulders. The inner foam core is typically of a substantially uniform thickness, and surrounds the entire upper portion of the wearer's head, extending from the forehead to the rear of the skull, down the sides of the head, and over the wearer's temples. The outer shell is likewise typically of a uniform thickness, surrounding the inner foam core, extending further down the sides and back of the wearer's head than the foam core. The helmet thus provides generally uniform impact protection to all areas of the wearer's head.
The present invention is directed to a batting helmet having localized impact protection, providing additional impact protection to areas of the helmet, typically to areas corresponding to the most vulnerable areas of the wearer's head, such as the temples, forehead, and crown. The helmet includes a rigid shell, with an attached padded inner core providing generally uniform padding and protection to the wearer's head. Localized protection is further provided at various areas on the helmet by providing additional stiffness or strength to the rigid outer shell in those areas or by including additional padding to the inner core or rigid shell in those areas. Thus, the areas of the helmet having localized protection provide an additional level of impact resistance to better deflect, disperse, or absorb impact in those areas to provide improved protection to the wearer. Because of the localized nature of the impact protection, the present invention can be implemented without substantially increasing the overall size and/or weight of a batting helmet.
In a first exemplary embodiment, a batting helmet having localized impact protection comprises a rigid shell having crown, front, back, left and right portions shaped to cover the respective crown, front, back, left and right portions of a wearer's head. A padded inner core, having a substantially uniform thickness, is affixed within the rigid shell so that the padded core covers and generally conforms to the crown, front, back, left, and right portions of a wearer's head. Additional padding is affixed to at least one of the crown, front, back, left, and right portions of the padded core so that a total thickness of padding in that area exceeds the thickness of the padded core alone. The additional padding thus provides localized impact protection to the corresponding area of the wearer's head by providing additional impact-absorbing material in that area. The rigid shell is formed with concave areas (or raised areas, when viewed from the outside) to conform to the additional thickness of the areas of the inner core having additional padding. In an alternative of this embodiment, the rigid shell is formed with areas having an increased thickness (as compared to the nominal thickness of the rigid shell) such that the increased thickness provides greater protection to the wearer. The rigid shell having increased thickness areas may be used in conjunction with a standard inner core or may be used in conjunction with an inner core having additional padding as just described.
In a second exemplary embodiment, a batting helmet having localized impact protection comprises a rigid shell, with a padded inner core affixed therein to cover the crown, front, back, left and right portions of a wearer's head. Additional padding is affixed to the outer surface of the rigid shell in an area corresponding to at least one of the crown, front, back, left, and right portions of the wearer's head, so that a total thickness of padding in that area exceeds the combined thickness of the rigid shell and padded inner core alone. The additional padding preferably comprises urethane strips or other impact absorbing material. The additional padding thus provides localized impact protection to the corresponding area of the wearer's head. Alternatively, the additional padding may be affixed to the inner surface of the rigid shell.
In a third exemplary embodiment, a batting helmet having localized impact protection comprises a rigid shell, with a padded inner core affixed therein to cover the crown, front, back, left and right portions of a wearer's head. Material having increased stiffness is positioned upon, or integral to, the rigid shell in an area corresponding to at least one of the crown, front, back, left, and right portions of the wearer's head, so that the total stiffness of material in that area exceeds the stiffness of the rigid shell alone. The material having increased stiffness preferably comprises carbon fiber, and is preferably positioned on the rigid shell as an insert, or by molding the material into the rigid shell. Alternatively, the material having increased stiffness may be attached to the outer or inner surface of the rigid shell in the desired areas. The increased stiffness of the rigid shell in those areas thus provides additional, localized impact protection to the corresponding area of the wearer's head.
Additional aspects of the invention, together with the advantages and novel features appurtenant thereto, will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned from the practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
The present invention will be described in greater detail in the following detailed description of the invention with reference to the accompanying drawings that form a part hereof, in which:
While the invention will be described in detail hereinbelow with reference to various exemplary embodiments, it should be understood that the invention is not limited to the specific configurations shown in these embodiments. Rather, one skilled in the art will appreciate that a variety of configurations may be implemented in accordance with the present invention.
A protective batting helmet having localized impact protection in accordance with a first exemplary embodiment of the present invention is depicted in
Rigid shell 12 includes a crown 18, a back 20, a front 22, a left side 24, and a right side 26, defining a front opening 28 corresponding to the area of the wearer's face, and defining the lower opening 14 for placing the shell over a wearer's head. The crown, front, back, and sides further define the inner cavity 16 which generally conforms to the shape of a wearer's head. Left and right ear covers 32a, 32b extend downwardly from the left and right sides 24, 26, respectively to cover the wearer's left and right ears, respectively. Left and right ear openings 34a, 34b through left and right ear covers 32a, 32b, respectively, provide ventilation to the wearer and allow the wearer to hear while wearing the batting helmet. Ventilation apertures 36a, 36b along the upper part of left and right side portions 24, 26, near crown 18, allow air circulation into and out of the helmet to cool the wearer's head. A bill 38 extends outwardly from front portion 22 of rigid shell 12 in the area generally corresponding to a wearer's forehead. Bill 38 is oriented to extend slightly upwardly from horizontal in normal wearing position, with the upper surface 40 of bill 38 shaped slightly convex to divert precipitation to the sides of the helmet. Bill 38 extends outwardly from front portion 22 to protect a wearer's eyes from sunlight and precipitation, without unduly limiting the wearer's upward view.
Protruding areas 42, 44 along the left side 24 and right side 26, respectively, provide space within inner cavity 16 for the placement of additional padding, as will be explained in more detail hereinbelow. The left and right protruding areas 42, 44 extend along the sides of the helmet, from a point generally above and forward of the wearer's ears, and wrap back along the sides to the rear of the helmet. The protruding areas 42, 44 are preferably formed integrally with the rigid shell such that the wall thickness of the rigid shell is substantially uniform, and so that the wall thickness of the rigid shell in a non-protruding area is substantially the same as the wall thickness of the rigid shell in a protruding area. The uniform thickness of the rigid shell walls throughout the rigid shell provides manufacturing advantages in molding and curing the shell.
Preferably, rigid shell 12 is constructed from a rigid, impact resistant material. Most preferably, rigid shell 12 is constructed of a rigid plastic material such as Acrylonitrile Butadiene Styrene (ABS) or polycarbonate. Rigid shell 12 is preferably formed as a unitary piece, including bill 38, using known processes such as molding or casting. Rigid shell 12 may be custom manufactured to accommodate head sizes from extra small (6⅜) to extra large (7½), or may be manufactured to intermediate or one-size-fits-all configurations.
Looking to
As described above, rigid shell 12 includes protruding areas 42, 44 which define spaces in the inner cavity portion of the shell. As can be seen in
Padded inner core 46 is preferably constructed from a semi-rigid, impact absorbing or resilient material, such as rubber or foam. Most preferably, padded inner core is made of expandable polystyrene (EPS) or expanded polypropylene (EPP). As described above with respect to rigid shell 12, padded inner core 46 may be custom manufactured to accommodate head sizes from extra small (6⅜) to extra large (8), or may be manufactured to custom, intermediate or one-size-fits-most configurations. Padded inner core 46 may be affixed to the rigid shell using any method known in the art, such as with glue or fasteners. Preferably the inner core is attached to the rigid shell using an adhesive.
Similar to the padded inner core, the additional padding 52, 54 is preferably constructed from a semi-rigid, impact absorbing or resilient material, such as rubber or foam. Most preferably, the additional padding is made of expandable polystyrene. Preferably, the additional padding is affixed to the padded inner core with an adhesive. Most preferably, the additional padding is formed integrally with the padded inner core.
Other configurations and embodiments are within the scope of the present invention. For example, additional padding may be placed only at the temple areas, or only at the crown area of the helmet. Or, additional padding may be placed at other desired locations, such as at the forehead. These and other variations are contemplated by, and within the scope of, the present invention. Likewise, other additional padding material may be used, such that the additional padding and the padded inner core are of different materials. Or, the additional padding could be positioned on the inside surface of the padded inner core. These variations, too, are within the scope of the present invention.
In addition to the padded inner core and additional padding, the batting helmet may be augmented with various sizes of removable pads attached within rigid shell 12 or to the inner surface of padded inner core 46 to precisely fit the batting helmet to a particular wearer. Any configuration of the helmet may include soft pads or padding at locations within the rigid shell or padded inner core to provide a snug, comfortable fit to the wearer's head as is known in the art.
In an alternative embodiment of the invention as just described with reference to
Furthermore, it should be apparent that the increased thickness of the rigid shell need not be dramatic and may be achieved by any increase in the thickness of the rigid shell beyond normal variations allowed in the manufacture of the shell. For example, normal manufacturing tolerances typically permit the nominal thickness of the rigid shell to vary plus or minus ten thousandths of an inch. Any increase of the thickness of rigid shell beyond that manufacturing tolerance is within the scope of the present invention. Preferably, the thickness of the rigid shell at the areas in which increased localized impact protection is desired is approximately at least 0.5 millimeters greater than the nominal thickness of the rigid shell.
A protective batting helmet having localized impact protection in accordance with a second exemplary embodiment of the present invention is depicted in
Rigid shell 112 includes a crown 118, a back 120, a front 122, a left side 124, and a right side 126, defining a front opening 128 corresponding to the area of the wearer's face, and defining the lower opening 114 for placing the shell over a wearer's head. The crown, front, back, and sides further define the inner cavity 116 which generally conforms to the shape of a wearer's head. Left and right ear covers 132a, 132b extend downwardly from the left and right sides 124, 126, respectively to cover the wearer's left and right ears, respectively. Left and right ear covers 132a, 132b present left and right ear openings 134a, 134b, respectively. A bill 138 extends outwardly from front portion 122 of rigid shell 112 in the area generally corresponding to a wearer's forehead.
As described above with respect to the first exemplary embodiment, rigid shell 112 is preferably made from a rigid material, such Acrylonitrile Butadiene Styrene (ABS) or polycarbonate. And, as described previously, rigid shell 112 may be configured in various sizes as desired.
Looking still to
Of course, other variations and configurations of additional padding are contemplated by the present invention. For example, the additional padding may be placed at other areas on the helmet, such as the crown or top of the helmet. Or the additional padding may be arranged in patterns other than the striped-pattern depicted in the exemplary embodiment. The additional padding need not be in strip form, but may be a pad or block, and may be constructed of a material other than urethane. Additionally, the additional padding may be placed on the inside surface of the rigid shell, and may be used whether or not the helmet also includes a padded inner core, as described above with respect to the first exemplary embodiment. Or, as described above with respect to the first exemplary embodiment, the thickness of the rigid shell may be increased at localized areas, that increased-thickness rigid shell may be used in conjunction with the additional padding as just described. These and other variations are within the scope of the present invention.
A protective batting helmet having localized impact protection in accordance with a third exemplary embodiment of the present invention is depicted in
Rigid shell 212 includes a crown 218, a back 220, a front 222, a left side 224, and a right side 226, defining a front opening 228 corresponding to the area of the wearer's face, and defining the lower opening 214 for placing the shell over a wearer's head. The crown, front, back, and sides further define the inner cavity 216 which generally conforms to the shape of a wearer's head. Left and right ear covers 232a, 232b extend downwardly from the left and right sides 224, 226, respectively to cover the wearer's left and right ears, respectively. Left and right ear covers 232a, 232b present left and right ear openings 234a, 234b, respectively. A bill 238 extends outwardly from front portion 222 of rigid shell 212 in the area generally corresponding to a wearer's forehead.
As described above with respect to the first exemplary embodiment, rigid shell 212 is preferably made from a rigid material, such Acrylonitrile Butadiene Styrene (ABS) or polycarbonate. And, as described previously, rigid shell 212 may be configured in various sizes as desired.
Looking still to
Of course, other variations and configurations of including material having increased stiffness in rigid shell 212 are contemplated by the present invention. For example, the material may be included at other areas of the helmet, such as the crown portion of the helmet. Or, the area of increased stiffness 258 may be achieved by providing an area of rigid shell 212 having an increased thickness (e.g., a thicker portion of Acrylonitrile Butadiene Styrene (ABS) in the desired area) such that the area has a greater stiffness than the other portions of rigid shell 212, with the increased thickness portion extending outwardly or inwardly from rigid shell 212. Or the increased stiffness material may be arranged in patterns along the helmet. And, as described previously, the material may be molded within or upon the rigid shell, or may be adhered to the rigid shell in the desired areas. Additionally, the increased stiffness material may be placed on the inside surface of the rigid shell, and may be used whether or not the helmet also includes a padded inner core. These and other variations are within the scope of the present invention
As can be seen, the invention described herein provides a batting helmet having localized impact protection that provides greater protection to a wearer. Because the added impact protection is localized, the invention does not substantially increase the size or the weight of the overall helmet. Thus, a wearer receives the benefit of localized impact protection without incurring increased overall size and/or weight of the helmet. While the invention has been described in conjunction with various exemplary embodiments, other embodiments or configurations are contemplated by and within the scope of the present invention. It should be understood that the invention described herein includes numerous features that have been described in conjunction with various exemplary embodiments. That those features may be arranged in various combinations, whether or not disclosed in a single embodiment herein, is contemplated by the present invention.
The term “substantially” or “approximately” as used herein may be applied to modify any quantitative representation which could permissibly vary without resulting in a change in the basic function to which it is related. For example, the wall thickness of the rigid shell 12 is described as being substantially uniform, but may permissibly vary from that diameter if the variance does not materially alter the capability of the invention.
While the present invention has been described and illustrated hereinabove with reference to various exemplary embodiments, it should be understood that various modifications could be made to these embodiments without departing from the scope of the invention. Therefore, the invention is not to be limited to the exemplary embodiments described and illustrated hereinabove, except insofar as such limitations are included in the following claims.
This application claims priority to and is a Continuation of U.S. patent application Ser. No. 12/550,514, filed on Aug. 31, 2009, which is incorporated herein by reference in its entirety.
