Description




FIELD OF THE INVENTION




The present invention generally relates to protective headguards for athletics, and more particularly, relates to an impact protective headguard for soccer players.




BACKGROUND OF THE INVENTION




Participants in many sports are increasingly using protective headgear of various kinds. Football players have long worn helmets to protect themselves from blows to the head and face. Sometime later hockey players also began to protect themselves with helmets. More recently recreational bicyclists have perceived the need to use protective headgear and have started to wear helmets in increasing numbers.




Traditionally, soccer players have not worn any protective headgear. This is probably the case for two main reasons. First, soccer players or organizers of the game may not have sensed a need to use headgear because injuries to the head may not have seemed as commonplace as in sports such as football, hockey, and bicycling. Second, soccer is one of the few sports where the head itself is intentionally and legitimately used to strike the ball. This requires considerable muscle coordination and use of the senses of sight and touch. An improperly constructed piece of headgear may hamper a player's ability to head the ball properly.




Recent medical research has demonstrated that head injuries may be more prevalent in soccer than previously thought. Several studies have suggested that soccer players may suffer minor trauma from repeatedly heading the ball. This injury has been analogized to pugilistic dementia, the harm that boxers suffer from repeated strikes to the head in boxing. Alf Thorvald Tysvaer, Head and Neck Injuries in Soccer - Impact of Minor Trauma,


Sports Medicine,


14(3):200-213 (1992). This danger of trauma in soccer may be greater for children. Their skills at heading are less well honed. Their bodies may not be developed enough to withstand or counteract the blow caused by a ball. Id. at 210. Therefore, at least from a safety standpoint, use of headgear by soccer players seems advisable.




The unique demands of the sport of soccer require unique headgear. Although multipurpose protective headgear for sports are being developed, most forms of headgear for use in team sports are intended for one sport and should not be used in other activities.

(May 8, 1996). A brief review of patents for headgear constructed for other sports shows how such headgear would not meet the specialized needs of soccer players. For example, football and hockey helmets are ill-suited for soccer. Their bulk would likely discourage soccer players unaccustomed to helmets from wearing them. In addition this bulk and the hard, sometimes uneven surfaces of such helmets would make it very difficult to control the direction and distance of a headed ball. Finally, other unprotected soccer players might suffer injuries caused by the hard-surfaced headgear of the wearer. See, e.g., U.S. Pat. No. 4,404,690 (hockey helmet).




Other helmets would also not work effectively as soccer headgear. Bicycle helmets are light but would make control of the ball difficult; they are built to withstand one substantial blow; and their ventilation systems would likely not be effective in soccer. See, e.g., U.S. Pat. No. 5,450,631. Wrestling headgear protects the ears and only incidentally, if at all, protects the surfaces of the head. See, e.g., U.S. Pat. No. 5,361,420.




U.S. Pat. No. 4,698,852 illustrates protective headgear specifically designed for use in soccer. This headgear, however, has several shortcomings. The headband shape of the headgear protects only the forehead, neglecting other parts of the head which may be used, properly and improperly, to strike balls. The headband shape moreover creates a ridge at the edge of the headband which may misdirect a headed ball. In addition, the materials and retention system of this headgear likely would cause the headgear to slip up or down on the wearer's head or, if tightened, may strain the wearer's head.




SUMMARY OF THE INVENTION




Generally, the present invention relates a headguard for athletics and in particular soccer players. In accordance with one embodiment of the invention, a protective headguard is provided that includes a central pad for covering a portion of a forehead of a wearer. The central pad has a first side and a second side, and a first and second padded rib extending from each side of the central pad. The distal ends of the first and second padded ribs on each side are connected to form side portions that extend rearward from the central pad for covering sides of the head of the wearer. The headguard further includes a rear pad that covers an occipital bone of the wearer. An adjustment strap system secures the side portions of the central pad to the rear pad.




A method of manufacturing a protective headguard is also provided. The method includes forming a planar pad having a central pad and first and second padded ribs extending from each side of the central pad. Further, the first and second padded ribs on each side are bent to contact a distal end of one of the first padded ribs with a distal end of a respective one of the second padded ribs. The contacted distal ends of respective first and second padded ribs are secured to form a multidimensional pad from the planar pad having side portions extending rearward of the central pad for covering sides of the head of a wearer.




The above summary of the present invention is not intended to describe each illustrated embodiment of the present invention. The figures and the detailed description that follow more particularly exemplify these embodiments.

DETAILED DESCRIPTION




The present invention is believed to be applicable to a number of different sports, and is particularly suited to soccer where players intentionally strike the ball with their head. While the present invention is not so limited, an appreciation of various aspects of the invention will be gained through a discussion of the exemplary embodiments in connection with the examples provided below.





FIGS. 1 and 2

illustrate one exemplary headguard in accordance with one embodiment of the invention. The headguard


10


includes a pad


100


, a head adjustment strap


102


, and a chin strap


104


. The pad


100


typically includes a spine


106


, a front panel


108


, a mid panel


110


, a crown panel


112


, two rear branches


116


, and a rear panel


114


. The front panel


108


and rear panel


110


form branches extending from a central pad portion


107


provided for covering a portion of a wearer's forehead. All of these pieces of padding are typically made of a shock-absorbing material such as foam which dissipates the force to the wearer's head when struck by an object and which is positioned on the headguard


10


to protect the regions of the wearer's head which may strike objects during the course of play. For example, the padding may cover the front, top, back and side areas of a wearer's head. This positioning of the padding is particularly suited for soccer players, who often use these areas of the head when striking a soccer ball.




The padding is typically sufficiently flexible so as to conform to unique head shapes and sizes. The position of the padding may be suitably selected in consideration of the particular environment in which the headguard is worn. For example, when used during the play of soccer, the padding may be positioned to provide a relatively uniform exterior surface over portions of a player's head which generally come in contact with a soccer ball, thus allowing greater control of the ball.




The thickness of the padding may be suitably selected in consideration of the portion of the head on which the padding is to cover as well as in consideration of the particular environment in which the headguard is worn. For example, the thickness of the padding may vary between the top, front, side, and back portions of the padding. Pad thickness around, for example, ⅜ to ⅝ inches, would be suitable for many applications.




The padding may further include apertures, such as channels, holes, or similar features, to circulate air through and ventilate moisture from the headguard. Suitable padding material includes solid and/or laminated foam, formed from plastic, for example.




In the exemplary embodiment, the spine


106


, to which all of the panels attach, runs from the forehead over the crown to the back of the head, just below the occipital bone; the front panel


108


covers generally the forehead and the temples; the mid panel


110


covers generally the front part of the head just above the forehead to the area just above the temples; the crown panel


112


covers the crown of the head, two rear branches


116


run from the crown of the head to the rear panel


114


; the rear panel


114


generally covers the back of the head near the occipital bone.




In this exemplary embodiment, the pad


100


is molded as a unified, generally flat (i.e., planar) piece, as illustrated in FIG.


2


. During assembly, parts of the pad


100


, as will be discussed below, are fastened together to create the multi-dimensional headguard


10


shown in

FIG. 1

from the flat piece of padding. The fastening typically occurs at zeros areas which are areas of thinner foam. Because zero areas are thinner, the overall thickness of the headguard can remain generally uniform even when the zero areas are fastened together in an overlapping position.




The pad


100


may have fabric laminated to the exterior surface and the interior surface of the pad


100


. The exterior fabric typically is durable and provides a surface that allows good control of the ball when heading the ball but is not so tactile that the headguard will grip objects, including the soccer ball, or extremities of other players.





FIG. 3

illustrates a partial exterior view of the pad


100


. In assembling the headguard


10


, the left and right distal ends of the front panel


108


are bent and fastened by stitches or other fastening mechanisms to the left and right distal ends of the mid panel


110


. The fastening occurs at the zero areas


122


of the front and mid panels


108


and


110


, as best illustrated in FIG.


3


. When those portions of the zero areas


122


of the front and mid panel


108


and


110


are fastened together, the headguard


10


curves in a way that conforms to the shape of the forehead and temples.




After fastening the front and mid panels, part


124


of the zero area


122


of each front panel


108


remains open. These remaining exposed portions


124


of the zero areas


122


are fastened to respective zero areas


124


of the crown panel


112


. When the zero areas


122


and


124


at the ends of the front, mid, and crown panels


108


,


110


,


112


are fastened together, the headguard


10


curves in a way that conforms to the shape of the front part of the head.




Open areas where padding does not cover the head provide ventilation and increase the plasticity of the padding. In this embodiment, these open areas are created in two ways. First, front vents


128




a


(shown in

FIG. 1

) are molded into the front and mid panels


108


and


110


and are molded into the crown panel


112


. In addition, front vents


128




b


(shown in

FIG. 1

) are created by seams between the front and mid panels


108


and


110


and between the mid and crown panels


110


and


112


when attached.





FIG. 5

is a rear view of the headguard


10


. As best illustrated in

FIG. 5

, after assembly of the front part of the headguard


10


, the rear panel


114


is fastened to the rear branches


116


. This fastening typically occurs at zero areas


132


on the rear branches


116


(shown in

FIG. 2

) and at the ends of rear ribs


130


(shown in

FIGS. 2 and 4

) located on rear panel


114


. The rear ribs


130


jut out from both the left and right side of the center pad portion


115


of the rear panel


114


that covers the occipital bone. The zero areas


132


of the rear ribs


130


and the rear branches


116


may be fastened in the same way as the zero areas


122


and


124


of the front, mid, and crown panels


108


,


110


, and


112


.




The zero areas of the panels and ribs and branches may, as an alternative to stitching, be fastened by means of an adjustable fastener such as a hook and loop fastener, for example, Velcro™. If this is done, the size and shape of the headguard


10


may be further adjusted to fit the unique sizes and shapes of different heads.




The bottom rear ribs


134


(and/or optionally the top rear ribs) may be molded at an angle to the other ribs as best illustrated in FIG.


2


. When the angled ribs and drawn parallel to the other rear ribs during assembly, the rear panel


114


bulges and increases the cupping of the rear panel


114


to the shape of the occipital bone. In addition, cupping of the rear panel


114


can be increased by making the ends of the rear ribs


130


that attach to the rear branches


116


narrower than the ends that are molded to the center portion


115


or the rear panel


114


. This permits the rear ribs


130


to be drawn closer at the ends attached to the rear branches


116


and causes bulging of the padding at the point where the rear ribs


134


are molded to the center portion


115


. Finally, varying the lengths of the rear ribs


130


may also increase the cupping to accommodate the occipital bone.




As illustrated in

FIG. 5

, gaps between the rear ribs


130


form rear vents


136


which increase ventilation and allow the foam to bend into the rounded shape that conforms to the back of the head without stressing the foam or causing bulging of the foam in unintended spots.




Optionally, the bottom rear rib


134


may be wider than the other ribs. This extra width permits different sized headguards to be made without creating more than one mold. For larger headguards to fit larger heads, the full width of the bottom rear rib


134


may be left intact. For smaller headguards to fit smaller heads, the width of the rib may be reduced in the assembly process.




The rear panel


114


is designed to protect the head from minor blows to the back of the head. Since the back of the head can be vulnerable to injury, this part of the headguard may be relatively thick as compared to the padding thickness of the front and mid panels


108


and


110


, for example.




When the rear branches


116


are attached, two roughly triangular areas


138


and


140


of the headguard, above the rear panel


114


, between the rear branches


116


, and on either side of the spine


106


may remain open as illustrated in FIG.


5


. The corresponding area of the head should be less vulnerable to injury and therefore need less protection. In addition, the openings may increase the ventilation. Loose fitting fabric


118


may cover the entire exterior as shown in

FIG. 6

or some portion of the headguard.




Expansion joints


142


and


144


, shown in

FIGS. 1 and 5

, may positioned to lie just behind the ears on both sides of the head by the front edge of the rear branches


116


and the rear edges of the front, mid, and crown panels


108


,


110


and


112


. The expansion joints


142


and


144


can expand or contract to fit uniquely shaped and sized heads. The head adjustment strap


102


maintains the proper size and fit during play. Elastic fabric may cover the expansion joints


142


and


144


.




In alternative embodiments, various modifications may be made to increase ventilation. For example the triangular areas


138


and


140


above the rear panel


114


may be enlarged; the number of rear ribs


130


may be reduced, the spine


106


may be reduced in width, the crown panel


112


eliminated, the mid panel


110


eliminated, the portion of the front panel


108


covering the temples may be eliminated; or the vents increased in size.




In this embodiment the head adjustment strap


102


(shown in FIGS.


1


and


6


), made of a stretchable material, runs from the forehead to the back of the head. In the forehead area, the adjustment strap


102


may rest in a slight recess


146


in the padding of the front panel


108


as illustrated in FIG.


3


. The recess


146


serves to maintain the position of the adjustment strap


102


. The head adjustment strap


102


runs along the left and right sides of the front panel


108


of the headguard


10


over approximately the top-third of an open area for the ears. The ears are typically recessed in a seam created by the expansion joints


142


and


144


.




As best shown in

FIG. 5

, the head adjustment strap


102


typically runs through two back loops


148


located on the rear panel


114


. The back loops


148


may be pass-throughs which are integrated into the foam/padding during the molding process or may be fabric sewn onto the rear panel


114


. The back loops


148


typically maintain the position of the head adjustment strap


102


so that it runs to a point just below the occipital bone where an adjustable fastener


150


completes the loop of the strap around the head. Mild tension on the head adjustment strap


102


typically holds the headguard


10


in place on the forehead above the brow and below the protrusion on the frontal bone and on the back of the head just below the occipital bone. This location of the strap


102


is desirable because the strap


102


will tend to shift or slide less. As a result, only mild tension on the adjustment strap


102


is typically necessary to keep the headguard in place. This mild tension reduces fatigue associated with a headguard that fits too tightly. The head adjustment strap


102


can expand or contract the expansion joints


142


and


144


and thereby permit the wearer to increase or decrease the size of the headguard


10


to fit the unique characteristics of the wearer's head.




A chin strap


104


may be attached to the headguard


10


to better retain the headguard on the head during play. As illustrated in

FIG. 1

, the chin strap


104


may be attached to the headguard


10


in four places, e.g., to the left and right sides of the rear panel


114


and to the left and right sides of the front panel


108


. This may be done, for example, by running the strap


104


through slots


152


in the rear panel


114


and panel


108


created during the molding process.




In this embodiment, the interior of the headguard which comes in contact with the head typically includes pillows


154


, as best illustrated in

FIGS. 2 and 7

. The pillows


154


are raised portions of the foam separated by interior channels


156


. The channels


156


may run in different directions to create pillows


154


of uniform height but of varying widths with generally three to four sides. The channels


156


may be molded into a v-shape or other shapes that makes the channel


156


wider at the point closest to the head of the wearer, as illustrated in FIG.


7


. This v-shape allows the parts of the headguard


10


to be more easily bent in shapes that conform to the head. It also allows the headguard


10


to be constructed from a thicker piece of foam to enhance the energy adsorbing capabilities of the headguard while still providing the flexibility of a thinner piece of foam which bends more easily into shapes that can conform to the head. The channels


156


also provide ventilation at the point where the headguard rests directly on the head. The channels


156


may advantageously be positioned so that air is directed to the vents to improve circulation.




Ventilation may be further increased in numerous ways as shown in FIG.


7


. First small cloth pieces


158


with adhesive backing or Velcro™, for example, may be attached to the pillows


154


in order to provide a sweat-absorbing layer between the pillows


154


and the head. Second, a light-weight, breathable and washable, inner cloth piece may be worn on the head to provide space between the foam of the pillows


154


and the head. Third, open-cell foam pieces


160


may be located on the interior of the headguard


10


in order to decrease the contact between the pillows


154


and the head. For example, open cell foam pieces


160


may have a v-shaped bottom configured to wedge into v-shaped channels


156


. In this way when an object strikes the headguard


10


, the open cell foam pieces


160


compress and the pillows


154


come in contact with the head and absorb and distribute the impact. Fourth, soft, sweat absorbent cloth may be laminated to the surface of the pillows


154


with the same general effect as the small cloth pieces


158


. Finally, the surface of the pillows


154


may be roughened with cross-hatching


162


to reduce contact between the foam pad


100


and the skin.




Use of the headguard will be described with reference to

FIGS. 1 and 5

. In use, a wearer typically slips the headguard


10


on the head and pulls the headguard


10


down on all sides so that the front of the headguard


10


sits directly above the brow on the forehead. Above each eye, the front vents


128




a


and


128




b


typically run perpendicular to a horizontal line in the middle of the forehead to points on either side of and just short of the crown of the head. The front panel


108


typically fits over the forehead and temple areas and continues to just above the ears. The lower parts of the two expansion joints


142


and


144


are typically positioned on either side of the head just in front of the ears. The rear panel


114


typically covers the occipital bone. By adjusting the tension of the head adjustment strap


102


and snapping the fastener


150


, the headguard


10


may be drawn into and remain in a shape that conforms to the head. If the chin strap


104


is attached, the chin strap


104


can be adjusted so that it does not chafe the neck or the underside of the chin but will prevent the headguard


10


from being displaced from the head during play.





FIG. 8

illustrates an exemplary headguard in accordance with another embodiment of the invention. The headguard


20


includes of a front panel


200


, a rear panel


202


, and two adjustable side fasteners


204


made of elastic or other stretchable material, for example. An optional spine


206


may be provided as illustrated in FIG.


9


. The panels


200


and


202


are typically made of a shock-absorbing material such as foam or padding which dissipates the force to the wearer's head when struck by an object and which is positioned on the headguard


20


to protect the regions of the wearer's head which may strike objects during the course of play. In this example, the panels


200


and


202


cover predominantly the front, part of the sides, and back parts of a wearer's head. If the spine


206


is added, part of the crown of the head may be covered. This positioning of the padding is particularly suited for soccer players, who often use these areas of the head when striking a soccer ball.




The padding in the panels


200


and


202


is typically sufficiently flexible so as to conform to unique head shapes and sizes. The position of the panel padding may be suitably selected in consideration of the particular environment in which the headguard


10


is worn. For example, when used during the play of soccer, the padding may be positioned to provide a relatively uniform exterior surface over portions of a player's head which generally come in contact with a soccer ball, thus allowing greater control of the ball.




The thickness of the padding may be suitably selected in consideration of the portion of the head which the padding is to cover as well as in consideration of the particular environment in which the headguard is worn. For example, the thickness of the padding may vary among the top, front, side, and back portions of the padding. Pad thickness around, for example, ⅜ to ⅝ inches, would be suitable for many applications.




The padding may further include apertures, such as channels, holes, or similar features, to circulate air through and ventilate moisture from the headguard. Suitable padding material includes solid and/or laminated foam, formed from plastic, for example.




In the exemplary embodiment, the front panel


200


covers generally the forehead and at least a portion the temples; the rear panel


202


generally covers the back of the head near the occipital bone; and the spine


206


, if included, attaches to the top of the front panel


200


, runs over the crown to the back of the head, just above the occipital bone, and attaches to the rear panel


202


.




As illustrated in

FIGS. 10

,


12


and


13


, the panels


200


and


202


are each typically molded as generally flat pieces. In assembly, parts of each panel


202


,


204


are fastened together to create the cupped front and rear panels


200


and


202


, shown in

FIG. 8

, that conform to that portion of the head which they cover. The fastening typically occurs at zero areas which are areas of thinner foam. Because the zero areas are thinner than adjacent padding, the overall thickness of the headguard


10


can remain generally uniform even when the zero areas are attached in an overlapping position.




The panels


200


and


202


may have fabric laminated to the exterior surface and interior surface. The exterior fabric typically is durable and provides a surface that allows good control of the ball when heading the ball but is not so tactile that the headguard will grip objects, including the soccer ball, or extremities of other players.




Turning back to

FIG. 10

, the front panel


200


typically includes a center pad


201


and a lower rib


210


and upper rib


212


extending from respective sides of the center pad


201


. On each side the lower and upper ribs


210


and


212


are bent and fastened by stitching or other fastening mechanisms to each other. The fastening occurs at the zero areas


214


of the lower and upper ribs


210


and


212


. To connect the two zero areas


214


of the lower and upper ribs


210


and


212


, the ribs are typically twisted and bent, causing the front panel


200


to change from a relative flat panel to a cupped shape. When the zero areas


214


of the lower and upper ribs


210


and


212


are fastened together, the front panel


200


maintains the cupped shape to better conform to the shape of the forehead and sides of the head.




With reference to

FIG. 10

, open areas or vents


216


and


218


where padding does not cover the head provide ventilation and increase the plasticity of the padding. These open areas


216


and


218


are created in two ways. First, front vents


216


are molded into the lower and upper ribs


210


and


212


. In addition, front vents


218


are created by the seams between the lower and upper ribs


210


and


212


when connected.




Turning now to

FIG. 11

, the front panel


200


may have a ridge


219


on the interior-side of the center pad


201


. When the headguard


10


is worn, this ridge


219


may be positioned just below the frontal bone to inhibit unintended slippage of the headguard


10


from its intended position. In addition, this ridge


219


may be covered with a non-slip material such as suede to further prevent slippage. The top edge


220


of the front panel


200


(and/or the edge


222


of the spine


206


if it is included) may also be tapered to graduate the rise from the exterior surface of the top


221


of the head to the exterior surface of the top edge


220


of the front panel


200


.




The rear panel


202


and assembly thereof will be discussed with reference to

FIGS. 12 and 13

. The rear panel


202


is assembled in a fashion similar to the assembly for the front panel


200


. In this embodiment the rear panel


202


includes a central pad


225


and a flange


227


extending from each side of the center pad


225


. Each flange


227


includes a middle rib


226


extending outward from a respective side of the center pad


225


and having a first end away from the respective side, an upper rib


228


interconnected between the first end and an upper portion of the respective central pad side, and a lower rib


224


interconnected between the first end and a lower portion of the respective central pad side. Zero areas


234


of the lower and upper rear ribs


224


and


228


are fastened to zero areas


234


on the four comers of the center portion


225


of the rear panel


202


in the same way that the zero areas discussed above with respect to the lower and upper ribs


210


and


212


of the front panel


200


are attached.




The zero areas of the front and rear panels


200


and


202


may be fastened by means of an adjustable fastener such as Velcro™, for example. If this is done, the size and shape of the headguard


20


may be further adjusted by the wearers to fit the unique sizes and shapes of different heads. In addition part of the assembly may be left to the wearer and shipping may be made easier.




The lower and upper rear ribs


224


and


228


may be molded at an angle to the middle ribs


226


. When the angled lower rib


224


, for example, is drawn closer to the middle rear rib


226


during assembly, the central pad


225


and ribs bulge and increases the cupping of the rear panel


202


to conform better with the shape of the occipital bone. In addition, cupping of the rear panel


202


can be increased by making the lower and upper rear ribs


224


and


228


shorter than the middle rear ribs


226


. This draws the upper and lower portion of the rear panel


202


inward and bulges the central pad


225


that covers the occipital bone outward.




The gaps between the rear ribs


224


,


226


, and


228


on each side form the rear vents


236


(shown in

FIG. 8

) can allow the foam to bend into the rounded shape that conforms to the back of the head without stressing the foam or causing bulging of the foam in unintended spot, and which can increase ventilation.




The lower rear ribs


224


may be molded to have a wider width than the upper rear ribs


228


. This extra width permits different sized headguards to be made without creating more than one mold. For larger headguards to fit larger heads, the full width of the lower rear ribs


224


may be left intact. For smaller headguards to fit smaller heads, the width of the lower rear ribs


224


may be reduced by cutting or other means in the assembly process.




The rear panel


202


is intended to protect the head from minor blows to the back of the head. Since the back of the head can be vulnerable to injury, this part of the headguard may be relatively thick as compared to the padding of the front panel


204


, for example.




Returning to

FIG. 8

, two side fasteners or straps


204


made of elastic or other stretchable material connect the front and rear panels


200


and


202


. In one embodiment the side fasteners


204


are positioned so that they are located slightly above and behind the ears on each side of the head. The side fasteners


204


may be attached to each panel


200


,


202


through slits


242


molded in the rear edge of the front panel


200


and the side edges of the rear panel


202


. Each side fastener


204


, once passed through each slit


242


, may be sewn or otherwise attached to itself to retain the side fastener


204


firmly to the front and rear panels


200


and


202


. To increase the adjustability of the side fasteners


204


, a sizing mechanism may be added to each side or one side to permit changes in the length of the elastic.




The front and rear panels


200


and


202


may be slightly offset with the lower edge of the rear panel


202


being lower than the lower edge of the front panel


200


. This offset of the rear panel


202


directs the primary line of tension created by the elasticity of the side fasteners from a point just below the occipital bone on the rear of the head to the depression in the forehead just above the brow and below the frontal bone.




Mild tension created by the elasticity of the side fasteners


204


and the give in the panels as they rest on the head of the wearer typically keeps the headguard


10


in place. Only mild tension is typically necessary because the line of tension follows the circumference of the head from a point just below the occipital bone on the rear of the head to the depression in the forehead just above the brow and below the frontal bone. This circumference is typically less than the circumference of the head from the top of the occipital bone to the top of the frontal bone. Therefore the line of tension is usually located in a depressed area which would reduce slippage over the top of the head.




Reduced tension is desirable because it tends to reduce fatigue associated with a headguard that fits too tightly. If a slide mechanism is added to the side fasteners


204


to further increase adjustability, the headguard


20


can further expand or contract and thereby permit the wearer to increase or decrease the size of the headguard to fit the unique characteristics of the wearer's head.




In a further embodiment, a chin strap


244


may be attached to the headguard


20


, as illustrated in

FIG. 15

, to better retain the headguard


20


on the head during play. The chin strap


244


may be attached to the headguard


20


at up to four places. For example the chin strap


244


may be a three strap system which includes two cords


246


running from a rear slot


248


on each front edge of the rear panel


202


to a front slot


250


on each side of the front panel


200


. Attached to the cords


246


may a slide strap


252


. The slide strap


252


may fasten to the cords


246


with Velcro™ or other fastener. For example, the ends of the strap


252


may include either a hook or loop material and inner parts of the strap


252


may include the mating material. The strap ends may be looped around the straps


246


and interconnected to the inner parts using the hook and loop material. The slide strap


252


may be placed on the cords


246


at a position that is comfortable to the wearer and may, for example, be attached at that point with the fastener


254


on both sides of the head. The fastener


254


typically releases if sufficient pressure is applied in order to prevent injury.




Referring back to

FIG. 9

, the optional spine


206


may also connect the front and rear panels


200


and


202


. The spine


206


is typically created along with the front and rear panels


200


and


202


during the molding process in the form of a single flat pad. After assembly, the spine


206


runs from the top of the front panel


200


over the crown of the head to the top of the rear panel


202


. The assembly may be carried out in the same fashion as with the headguard


20


of FIG.


8


. The spine


206


can provide additional protection to the head and may assist in preventing slippage of the headguard over the brow or down the neck.




In an alternate embodiment, the headguards of

FIGS. 8

or


9


may be molded into their final shape through a process such as injection molding. In this manner, assembly, such as stitching zero areas, may be eliminated and the headguard may be molded to a cupped shape that conforms to the head.




The interior of the headguard


20


which comes in contact with the head may include pillows


256


, as illustrated in

FIGS. 8 and 12

. The pillows


256


are raised portions of the foam separated by channels


258


. The pillows


256


may be formed in a similar manner as and have the same general characteristics as the pillows discussed above.




In one embodiment shown in

FIG. 14

, the pillows


256


of the rear panel


202


define a circular or semi-circular depression


240


on the interior-side of the rear panel


202


in the area for covering the occipital bone. The purpose of this depression


240


is to improve retention of the headguard on the head and to disperse energy from a blow to the back of the head away from the top of the occipital bone and to the upper neck and a larger area of the head.




In use, a wearer typically slips the headguard


20


on the head and pulls the headguard


20


down on all sides so that the front panel


200


sits directly above the brow on the forehead. The front vents


216


typically run horizontally on either side of the midpoint of the forehead to a height short of the crown of the head. The front panel


200


typically fits over the forehead and part of the temple areas and continues to just above the ears. The rear panel


202


typically covers the occipital bone and part of the area around it. The side fasteners


204


stretch as the wearer dons the headguard


20


to fit the head of the wearer. If an additional adjustable slide is added to the side fasteners


204


, adjustment can be further enhanced. If the chin strap


244


is attached, the chin strap


244


can be adjusted so that it does not chafe the neck or the underside of the chin but will prevent the headguard


20


from being unintentionally displaced from the head during play.





FIG. 16

illustrates further exemplary headguard in accordance with another embodiment of the invention. The headguard


30


typically includes a front panel


302


, a rear panel


304


, and adjustment strap system, for example, two or more adjustment straps


306


made of elastic or other stretchable material. An optional spine


308


may be provided as illustrated in FIG.


17


.




The panels


302


and


304


are typically made of a shock-absorbing material such as foam which dissipates the force to the wearer's head when struck by an object such as a ball. The foam or padding of the headguard


30


is intended to protect the regions of the wearer's head which may strike objects during the course of play. The foam may have fabric laminated to it on the interior and/or exterior surfaces. In this embodiment, the panels


302


and


304


cover predominantly the forehead, the sides from just below the crown and down to the upper part of the temples, and the back of the wearer's head around the occipital bone. If a spine is added, part of the crown of the head may be covered. This positioning of the padding and the location of open areas in the foam is particularly suited for soccer players, who often use these areas of the head when striking a soccer ball.




The padding in the panels is typically sufficiently flexible so as to conform to unique head shapes and sizes. The position of the padding may be suitably selected in consideration of the particular environment in which the headguard is worn. For example, when used during the play of soccer, the padding may be positioned to provide a relatively uniform exterior surface over portions of a player's head which generally come in contact with a soccer ball, thus allowing greater control of the ball.




The thickness of the padding may be suitably selected in consideration of the portion of the head which the padding is to cover as well as in consideration of the particular environment in which the headguard


30


is worn. For example, the thickness of the padding may vary among the top, front, side, and back portions of the padding. Pad thickness around, for example, ½ to ⅝ inches, would be suitable for many applications. Suitable padding material includes solid and/or laminated foam, foam formed from plastic, for example, and foam laminated with fabric on the interior or exterior surfaces.




As illustrated in

FIG. 18

, the front panel


302


is typically made from a flat piece of foam molded or cut into the proper shape which also can have fabric laminated to either or both sides. Referring now to

FIGS. 16 and 18

, the front panel


302


has two lower ribs


310


,


312


and two upper ribs


314


,


316


emanating from respective sides of a center front pad


318


which typically covers at least part of a wearer's forehead.




On a portion of the exterior surface of each lower rib


310


,


312


is a thinner area or zero area


320


. For the zero areas


320


a thickness for the padding of approximately ⅛ inch would be suitable. The interior surface of each upper rib


314


,


316


may have a receiving depression


322


(shown in

FIG. 19

) which typically corresponds to the size and shape of the zero areas


322


on the lower ribs


310


,


312


. The depth of the receiving depressions


322


typically is about equal to the thickness of the zero areas


320


on the lower ribs


310


,


312


.




In assembly, the upper and lower ribs


310


-


316


are bent so that the zero areas


320


of the lower ribs


310


,


312


align with the receiving depressions


322


of the upper ribs


314


,


318


. The left lower and upper ribs


312


,


316


attach to each other, and the right lower and upper ribs


310


,


314


attach to each other. By bending the ribs


310


-


316


in this fashion, the center front pad


318


is typically pushed outward, and the front panel


302


takes on a cupped shape that more closely conforms to the shape of the human head. The thickness of the padding at points where the zero areas


320


and the receiving depressions


322


overlap is typically about equal to the thickness of the padding thicker portions of front panel


302


.




In order to maintain the cupped shape of the front panel


302


, the upper and lower ribs


310


-


316


on each side may be permanently attached to each other at the overlap of the zero areas


320


and receiving depressions


322


by stitching, or they may be attached by hook and loop fasteners. The hook and loop fasteners may be located on the zero areas


320


and receiving depressions


322


for disposal between these structures. Use of hook and loop fasteners permits easy disassembly of the front panel


302


.




When assembled, the front panel


302


typically defines three vents on either side of the center front pad


318


. A aperture or seam vent


326


is created on each side between the upper and lower ribs


310


-


316


of each side when they are bent and attached. In addition two vents


328


are molded or cut into each of the lower ribs


310


and


312


.




To aid in flexing the pads to conform to the head, channels may be molded into the exterior surface at different locations to create flexing areas


332


,


334


,


336


. One or more channels may, for example, be disposed between each of the upper ribs


314


,


315


and the central pad


318


for increasing flexing between these ribs and the central pad.




A detailed view of an example flexing area


338


is shown in FIG.


20


. The flexing areas


332


,


334


,


336


are located in several spots on the front panel


302


. The flexing areas function as hinges by increasing the ability of the foam to flex and curve in order to conform to the shape of the head.




The padding is thinner at the base of the channels thus increasing the flexibility of the foam generally in the direction opposite the direction of the channels.




The channels allow the padding to bend along the channels. As noted above, a flexing area may consist of one or more channels. If there is more than one, the channels run generally parallel to each other (although non-parallel channels from different flexing areas may intersect). While flexing areas with one to four channels are disclosed, the invention extends to cover flexing areas with more channels.




The channels of the flexing areas


332


,


334


,


336


are molded into the exterior surface of the front panel


302


at points where the front panel


302


desirably curves most severely in order to conform to the shape of the head. For example, the flexing areas


334


are located at the portion of the front panel


302


which typically rests on the part of the head that forms the transition from the forehead to the side of the head. The channels of the flexing areas


332


,


334


typically run at angles to the bottom or top edges of the assembled front panel between 45 and 90 degrees thereby increasing the ability of the front panel to wrap around the head. The channels in flexing areas


332


,


334


may run approximately along the same line as and along side the vents


328


and


326


in the front panel


302


as shown. Another flexing area


336


may surround the frontal bone, which on some wearers protrudes outward.




As best shown in

FIGS. 16 and 18

, the front panel


302


includes four attachment points


340


which serve as locations where the adjustment straps


306


may be attached to the front panel


302


. The attachment points


340


are typically areas where slots


342


-


348


are molded into the foam as shown best in FIG.


18


. Alternatively, the attachment points


340


may be small depressed areas as shown in

FIGS. 21A and 21B

suitable for sewing attachment rings


352


and


354


.




The attachment points


340


with slots


342


-


348


are shown in

FIG. 16

in a fully assembled state and in

FIG. 18

in the unassembled state. The slots


342


-


348


are openings molded or cut through the entire thickness of the padding through which the adjustment straps pass. The slots


342


-


348


may be of varying sizes but must be of a size to permit the adjustment strap


306


to pass through. A slot length of ⅝ to ¾ inches, for example, may be suitable.




To form the assembled front panel


302


of

FIG. 16

, the upper slots


346


,


348


may overlap with slots


350


(shown in

FIG. 18

) located in the zero areas


320


of lower ribs


310


and


312


when the zero areas


320


and the receiving depressions


322


are bent together. When the upper and lower ribs


310


-


316


are joined together in assembly these slots


346


,


348


,


350


align to form one set of upper slots on each side of the front panel


302


as shown in FIG.


16


.




In the alternative embodiment, shown in

FIGS. 21A-B

and


26


, the attachment points


340


are created by attaching, for example, attachment rings


352


,


354


made of fabric, rubber, or other soft material, to the rear edges of the front panel


302


. A depressed area can be molded into the rear edges at the attachment points


340


. The rings


352


,


354


may be attached by sewing the attachment rings


352


,


354


to the ribs


310


and


314


with a piece of fabric


356


. This same sewn seam may also permanently secure the upper and lower front ribs to each other.




Attachment of the adjustment straps


306


to the front panel


302


with rings can permit the adjustment straps


306


, when attached to the attachment rings


352


,


354


to slide up and down along the rings


352


,


354


. This can permit the rear panel


304


to be readily positioned at different heights in relation to the front panel


302


without binding of the adjustment straps


306


.




Referring to

FIG. 22

, the rear panel


304


in the embodiment of

FIG. 16

, includes six rear ribs


360


-


370


integrally formed with a center pad


358


pad during the molding process. Three of the rear ribs


360


-


364


project downward from the center pad


358


and three ribs


366


-


370


project upward. Slots


372


-


382


are located near the ends of the ribs


360


-


370


away from the center rear pad


358


. All slots


372


-


382


in this embodiment run generally parallel to the length of the ribs. All slots


372


-


382


in this embodiment for the rear panel


304


are also approximately the same size as the slots


342


-


348


for the front panel


302


described above.




At certain points slight depressions


384


, in which the adjustment straps may lay, may be molded into the foam to guide the adjustment straps as they cross the rear ribs. These depressions


384


may be of the same depth as the thickness of the adjustment straps


306


. An upper strap


306


shown interweaving through the ribs


366


-


370


of the rear panel


304


is depicted in FIG.


23


. As shown in

FIG. 16

, the lower strap


306


may interweave through the rear panel


304


in the same manner.




In an alternative embodiment illustrated in

FIG. 24

, the rear panel


304


has four ribs


386


-


392


emanating from a center rear pad


359


. Two of the rear ribs


388


,


392


emanate generally horizontally to the left from one side of the center rear pad


359


and the other two


386


,


390


emanate generally horizontally to the right direction from the other side of the center rear pad


359


. At the end of each ribs


386


-


392


a ring may be attached similar to the rings


352


,


354


attached to the rear edge of the front panel


302


. Alternatively, slots


394


may be molded into the foam of the ribs


386


-


392


as shown in FIG.


24


. The slots


394


are typically located near the end of the rear ribs away from the center rear pad


359


. The slots


394


may be positioned at roughly a 90 degree angle to the length of the rib. The slots


394


may be of the same size as the ones described above. At certain points, the adjustment straps


306


cross the exterior or interior surface of the rear panel


304


. At these locations, depressions


396


in which the adjustment straps


306


may be disposed, may be molded into the foam to guide the adjustment straps


306


over the exterior or interior surface of the rear panel


302


.

FIG. 25

shows the interior of this rear panel


304


with the adjustment straps


306


looped through the slots


394


.




The space between the rear ribs of both embodiments form the rear vents


398


which can allow the foam to bend into the rounded shape that conforms to the back of the head without stressing the foam or causing bulging of the foam in unintended spots and can increase ventilation. Unlike the front vents


326


,


328


, the rear vents


398


are typically not filly enclosed by padding.




Similar to the front panel


302


, either rear panel


304


embodiment may have flexing areas


400


integrated into the exterior surface. For example, flexing areas


400


may be formed from one or more channels molded into the padding in an area surrounding the occipital bone as is shown in

FIGS. 22 and 24

. This allows the rear panel


304


to bend more easily and better conform to the protrusion of the occipital bone on the back of the head of most wearers.




The rear panel


304


is intended to protect the head from minor blows to the back of the head. Since the back of the head can be vulnerable to injury, this part of the headguard may be relatively thick.




There are two to four adjustment straps


306


disclosed in this invention. The rear panel


304


with six rear ribs depicted in

FIGS. 22 and 23

works optimally with two adjustment straps. The rear panel


304


with four rear ribs depicted in

FIGS. 24 and 25

works optimally with four adjustment straps


306


. The same front panel


302


may be used with any of the various embodiments of rear panels.

FIGS. 29 and 30

, for example, show the front panel


302


with a four rib rear panel


304


.




The size and shape of and the materials for the adjustment straps


306


may vary. The adjustment straps


306


may be cylindrical, flat, or oblong. They may vary in width from approximately ⅛ to 1 inch. They may be made of material such as rubber, elastic, or any other stretchable material. The adjustment straps


306


disclosed are generally flat on two sides and between ⅜ to ½ inch in width. Use of adjustment straps


306


of a different size and shape would require alteration of the size and shape of the slots.




The two adjustment straps


306


are connected to the rear panel


304


with six ribs as follows and as shown in FIG.


23


. Both adjustment straps


306


are threaded through the slots molded into the ends of the ribs of the rear panel in the same fashion. For example, the adjustment strap


306


for the upper ribs


366


-


370


is passed through the two slots


382


of the middle upper rear rib


368


from the exterior to the interior sides. The middle of the adjustment strap is typically positioned at the midpoint of the two slots


382


of the middle upper rear rib


368


. The adjustment strap


306


is looped back out to pass through the upper right rear slot


376


and upper left


378


rear slot, again from the exterior to the interior side. Equal lengths of the adjustment strap typically extend from both the upper right and left rear ribs


366


,


370


.




Four adjustment straps


306


may be connected to the rear panel with four ribs


386


-


392


as shown FIG.


25


. Each adjustment strap


306


is connected to each of the ribs


386


-


392


in the same way. For example, an adjustment strap


306


is drawn through the slot


394


of the upper left rear rib


392


. (In the place of the slots


394


, rings similar to the attachment rings


352


,


354


described above may also be attached to the rear panel


304


.) After being drawn through the slot


394


, that end of the adjustment strap


306


is folded into a loop and attached permanently to itself by a sewn joint


408


or other attachment means as shown. In the same fashion, each of the remaining three adjustment straps is attached to the remaining three ribs.




Regardless which rear panel


304


embodiment is employed, once the adjustment straps


306


are attached to the rear panel


304


as described above, four ends of the adjustment straps


306


extend from the rear panel


304


and connect to the front panel


302


. As illustrated in

FIGS. 21A and 21B

, to the ends of each upper and lower adjustment strap, a set of hook and loop fabric strips


404


,


406


is attached. For example, a hook fabric strip


404


is attached to one of the flat sides of one of the adjustment straps. At a distance from the end of the adjustment strap, a strip of looped fabric


406


is attached to the same flat sides of the adjustment straps. The distance the strips of hook and loop fabric are located from each other is dependent of the size of the head the headguard is intended to protect. Each end of the adjustment strap is looped through the rings


352


and


354


(or alternatively slots). Each end of the four adjustment straps is attached to the front panel


302


in this way. By varying the point at which the hook and loop fabrics are joined, the straps may be independently adjusted and the fit of the headguard can be adjusted.




Other means of attaching the end of the adjustment straps


306


to the front panel may include slide fasteners instead of hook and loop fasteners. Slide fasteners may slide into place and then lock in position to maintain the fit desired by the wearer.




Turning now to

FIGS. 19 and 25

, to expand sizing capabilities and to improve ventilation, sizing pads


410


-


414


may be attached to the interior of the headgear


30


. These inserts may be attached to the interior surface with hook and loop fasteners. Sizing pads


410


,


412


suitable for the interior of the front panel


302


are shown in

FIG. 19 and a

sizing pad


414


suitable for the rear panel is shown in FIG.


25


. The sizing pads


410


-


414


serve several purposes. By raising the front or rear panel from the head, air space between the head and the panels of the headguard may be created to enhance ventilation. Second, the sizing pads enhance the ability of the headguard to be fitted to the size and shape of the wearer's head. This aids both in retaining the headguard on the wearer's head in achieving a more comfortable fit. Finally, the foam inserts may be easily removed and washed.




The sizing pads


410


-


414


may be made of different materials. Open-cell foam with cloth laminated to one or both sides would function well. The thickness of the sizing pads may vary. Thicknesses from ⅛ to ⅜ inch would be preferable. Multiple pads may be used for both the front and rear panels or a single pad for the front and a single pad for the rear panel may be employed.

FIG. 19

shows an embodiment with multiple pads


410


,


412


for the front panel


302


and

FIG. 25

shows an embodiment with a single pad


414


for the rear panel


304


. The sizing pad


414


on the rear panel


304


is intended to be located beneath the occipital bone thus forming a ridge which is intended to reduce the slippage of the rear panel


304


over the occipital bone when the headguard is worn. The sizing pad


414


may align with lower adjustment straps


306


. Similarly, as shown in

FIG. 19

, the sizing pad


410


located at the center of the interior side of the front panel


302


may form a ridge to prevent slippage of the front panel


302


over the frontal bone when the headguard is worn.




Turning now to

FIGS. 27 and 28

attachment of the sizing pads will be discussed. The sizing pads


410


-


414


may be attached to the interior of the headguard using hook and loop fasteners. A slight depression


416


of approximately ⅛ inch or less in depth is typically molded or cut into the interior side of a panel at the point where the hook and loop fasteners for a sizing pad are to be positioned. The depressions


416


for the hook and loop fasteners are identified by the circular dashed lines in

FIGS. 19 and 25

.




Two methods of attaching the sizing pads are disclosed here and illustrated in

FIGS. 27 and 28

. In

FIG. 27

, the fabric


418


laminated to the sizing pads and the fabric


420


laminated to the interior of the panels may be loop fabric as shown. Circular strips of fabric


422


with loops on both sides may be placed in the circular depressions


416


intended for them. The hooks of the circular strips of fabric


422


attach to the fabric


420


laminated to the interior side of the panel. The sizing pad


412


is placed in proper position and the loop fabric


418


of the sizing pad attaches to the exposed loops of the circular strips as shown in FIG.


27


. To enhance the ability of the sizing pads to conform to the head, channels


424


, as shown in

FIG. 19

, may be permanently pressed into the sizing pads at those locations where the sizing pads bend to conform to the curves of the head.




A second method of attaching sizing pads is shown in FIG.


28


. The key difference in this second method of attachment is that the hook fastener


426


is single-sided and the side faces toward the interior side which attaches to the sizing pad. The other side is attached to the interior side of the panels by adhesive other means.




The chin straps disclosed in earlier embodiments may also be employed with the headguard


30


. Alternatively, a chin strap


428


of stretchable material, for example, elastic or rubber cord, may be provided as shown in FIG.


29


. The two ends of the chin strap


428


may be attached to the front panel


302


of the headguard


30


at two points on the front panel


302


located in a downwardly extending portion or protrusion


430


for covering a temple. Hook and loop fasteners on the end of each cord and on the protrusion


430


may be used to secure the chin strap


428


and ensure that the chin strap


428


detaches from the headguard


30


if sufficient force is applied. The chin strap


428


may release if sufficient pressure is applied in order to prevent injury.




The optional spine


308


runs from the top middle portion of the front panel to the top portion of the rear panel as shown in FIG.


19


. The spine


308


may be of any width depending on the amount of the top part of a head desired to be covered.




In alternative embodiments, front panel


300


may be molded in the shape shown in

FIG. 16

, for example, through a process such as injection molding. This allows the front panel


300


to be formed in a cupped shaped with requiring stitching or otherwise fastening ribs. The rear panel


302


may also be injection molded if desired. The adjustments straps may attach to the front and rear panels in the same fashion as described above.




In use, a wearer typically slips the headguard


30


on the head and pulls the headguard down on all sides so that the front panel should preferably sit directly above the brow on the forehead. A headguard fitted on the head of a wearer is shown in

FIGS. 29 and 30

. As illustrated in

FIGS. 29 and 30

, above each eye, the seam vents run at between 20 to 90 degree angles toward the crown of the head. The other vents


328


run approximately parallel to the seam vents


326


. The front panel


302


fits over the forehead and part of the temple areas and continues to just above the ears. The rear panel


304


covers the occipital bone and part of the area around it. The adjustment straps


306


stretch as the wearer dons the headguard to fit the head of the wearer. The fit of the headguard can be changed by adjusting the adjustment straps


306


. If the chin strap


428


is attached, the chin strap


428


can be adjusted so that it does not chafe the neck or the underside of the chin but will prevent the headguard from being unintentionally displaced from the head during play.




Mild tension created by the elasticity of the adjustment straps


306


and the flexibility in the panels


300


and


302


as they rest on the head of the wearer should be sufficient to keep the headguard in place. Reduced tension is preferred because it will reduce fatigue associated with a headguard that fits too tightly. Only mild tension is typically necessary because the line of tension follows the circumference of the head from a point just below the occipital bone on the rear of the head to the depression in the forehead just above the brow and below the frontal bone. This circumference should be less than the circumference of the head from the top of the occipital bone to the top of the frontal bone. Therefore the line of tension would be located in a depressed area which would reduce slippage over the top of the head. In addition, the ridge formed by the brow should prevent undue slippage over the face.




This line of tension will differ on different users because head shapes and sizes differ. Because of this the headguard typically is adjustable. The headguard disclosed here adjusts in the following ways. First, the rear panel


304


can move up and down and typically left and right in relation to the front panel


302


because the adjustment straps


306


connecting the panels are flexible. This flexibility is enhanced if attachment rings are attached at the rear edge of the front panel


302


. Second, the flexibility of the panels, enhanced by the pliability of the padding, the flexing areas, and the vents


326


, permit greater conformity to the shape of the head and better retention. For example, the rear panel


304


can flex inward in the area underneath the occipital bone thereby fitting the occipital bone. Third, the four adjustable fasteners on the adjustment straps allow increased or decreased tension to be pinpointed. If, for example, too much tension is placed below the occipital bone and the headguard becomes uncomfortable, either the lower adjustment straps can be loosened or the upper straps can be tightened. Finally, the sizing pads can act as additional means for retention and sizing. In some locations tension cannot be directed sufficiently to bend the panels in such a way that improves retention and sizing. For example, in the depressed area between the brow of the head and the frontal bone it may be difficult to depress the front panel sufficiently to achieve optimal retention. By placing a sizing pad in this area, conformity to the head is increased and the ridge formed by such a sizing pad reduces the likelihood the panel will slip over the top of the head.




As noted above, the present invention provides a headguard which may be used in a number of different sports in which impacts to the head may occur. The present invention should not be considered limited to the particular examples described above, but rather should be understood to cover all aspects of the invention as fairly set out in the attached claims. For example, while suitable materials, fasteners, and the like have been disclosed in the above discussion, it should be appreciated that these are provided by way of example and not of limitation as a number of other materials, fasteners, and so forth may be used without departing from the invention. Various modifications as well as numerous structures to which the present invention may be applicable will be readily apparent to those of skill in the art to which the present invention is directed upon review of the present specification. The claims are intended to cover such modifications and structures.
