Definitions

  • the invention relates to a face guard for use by athletes.
  • the invention relates especially to a face guard for baseball players, particularly although not exclusively, for young baseball players.
  • the need for certain athletes to wear protective gear to protect the head and face has long been recognized.
  • players wear helmets having face guards to protect the head and facial areas.
  • the face guard of the invention is adaptable to many sports, (e.g., soft ball, racquetball, lacrosse, field hockey); however, the discussion of the related art will focus primarily on practices which relate to use of the invention face guard in connection with baseball. It is to be understood however that the face guard of the invention is not limited to that sport.
  • a baseball player in particular a young player who is just learning the game, is subject to a number of injuries which could be diminished or avoided by a protective face guard.
  • Players often risk being struck by hit or deflected balls, for example by line drives which come directly and quickly off a batter's bat, by ground balls which can bounce off the ground and hit a player's chin or face, or by collision with another player.
  • protective gear allows athletes who wear the protective gear to feel more at ease about performing to the limit of their athletic ability without fear of injury, and as a result develop confidence in their playing ability and become more skilled in the game pursued.
  • a protective face guard is not effective or successful if the player will not wear it.
  • Protective face guards have previously been developed, for example, as illustrated in United States patent No. 3,132,345 of Keith. However, no face guard has proven completely successful for use by baseball players, particularly young players playing in defensive positions.
  • a face guard which requires special cap attachments (for example, of the type shown in the patent of Keith) is cumbersome to put on and remove, and thus is not a practical option.
  • An effective and successful protective face guard must meet several goals.
  • An effective face guard must be easy to put on, take off, and wear.
  • the face guard must not obstruct a player's ability to see and watch a ball, other players or the field.
  • the face guard must also conform to league uniform regulations, which typically require the wearing of a league baseball cap.
  • the face guard should not, therefore, prevent the player from wearing a baseball cap.
  • a cap protects a player's head from the sun, and provides a sun visor.
  • a face guard which requires that the baseball cap be removed or turned backwards on the player*s head hinders the ca 's ability to protect the player. If a protective face guard does not meet these recited goals, a player will not wear the face guard, and thus will not be protected during play.
  • the face guard of the invention is designed for players in defensive positions and is not meant to replace the head gear specially designed for offensive players, catchers and base coaches.
  • a mouth guard is used in conjunction with the face guard of the invention.
  • One advantage of the sports face guard of the invention is that it is easy and convenient to use.
  • Another advantage of the face guard of the invention is its adaptability to the protection of young baseball players, particularly those players playing defensive positions.
  • the face guard of the invention is comprised, according to a first embodiment, of a one-piece lightweight molded mask piece, a forehead pad and a mouth pad both of which are secured to the inside surface of the mask piece, a strap and a mouth guard.
  • the mask piece is formed from a relatively thin plastic material having high impact strength and may be tinted.
  • the uppermost edge of the mask piece resides slightly above the player's head.
  • the lowermost edge of the mask piece resides below the player's chin to cover the player's throat area.
  • the mask piece extends from the temple area of one side of the player's face to the temple area of the opposite side of the player's face.
  • the mask piece instead of being formed of a molded plastic is formed as a matrix of intersecting rod members which provides similar protection as with the face guard of the parent application and preserves all of the described features.
  • a particular feature of the face guard of the invention is that the mask piece is formed with a visor aperture which is sized and positioned to accommodate the insertion of the bill of a regulation baseball cap.
  • the mask piece of the face guard is also formed with a vision aperture such that, when the face guard is worn, the vision aperture is positioned opposite the player's eye area.
  • the vision aperture is somewhat oval shaped to provide the player with an unobstructed forward and substantially unobstructed peripheral view.
  • the lower portion of the vision aperture extends below the player's sight line to a level slightly above the tip of the player's nose so as to guard the player's nose.
  • the vision aperture is sized smaller than the diameter of a baseball at the opening's widest point.
  • the face guard is equipped with a forehead pad and a mouth pad which effectively position the face guard relative to the player's face.
  • the thickness of the pads permits the player to wear glasses when wearing the face guard of the invention, and without experiencing any loss of forward or peripheral vision.
  • the forehead and mouth pads also protect and cushion the player from the impact of blows to the face guard by hit or deflected balls by distributing the impact through the mask piece and the pads.
  • Figure 1 is a front perspective view of the face guard of the invention without a mouth guard.
  • Figure 2 is a front view of the face guard of Figure 1.
  • Figure 3 is a side view of the face guard of Figure 1 with a mouth guard inserted.
  • Figure 4 is a top view of the face guard of Figure 3.
  • Figure 5 is a rear view of the face guard of Figure 1.
  • Figure 6 is a cross-sectional view taken along line 6-6 of Figure 4.
  • Figure 7 is a side view of a player (in dashed lines) wearing the face guard of the invention and illustrated as wearing a mouth guard.
  • Figure 8 is a front elevation view of a second preferred embodiment of the face guard of the invention.
  • Figure 9 is a side elevation view of the face guard of Figure 8 with a wearer (in dashed lines) .
  • Figure 10 is a cross section view taken in the direction of line 10-10 of Figure 8.
  • Figure 11 is an exploded cross sectional view taken in the direction of line 11-11 of Figure 8.
  • the face guard 20 of the invention is generally comprised of a mask piece 22, a strap 46, a forehead pad 50, a mouth pad 52, and a mouth guard 64.
  • Mask piece 22 is preferably formed from a tough, rigid, non-shattering, molded plastic material which can resist and deflect direct hits by a baseball or the like.
  • Mask piece 22 is preferably formed by injection molding.
  • a polycarbonate material such as the polycarbonate material sold under the name LEXANTM, is particularly suitable for making the mask piece 22 because of its high impact strength, its capability for being tinted and for providing a non-reflective exterior surface when molded.
  • a non-reflective exterior surface on mask piece 22 reduces sun and artificial light reflected off the mask piece 22, and tinting reduces harmful sun rays from penetrating the mask piece 22.
  • a tinted mask piece 22 also gives the face guard 20 an aesthetically pleasing appearance.
  • mask piece 22 is assumed to be made of a transparent, non-reflective material.
  • Mask piece 22 has a generally outward curvature so that it guards the player's face and also assists in deflecting balls.
  • Mask piece 22 includes a front portion generally designated 26 and integrally connected side portions generally designated 34, shown from a front view in Figure 2 and from a top view in Figure 4.
  • Side portions 34 include upper regions 36, as indicated in Figures 1-3 and 5-7, which are designed to cover the player's temple areas.
  • Side portions 34 also include lower regions 38 indicated in Figures 2 and 7 which are designed to cover the player's cheek and jaw areas.
  • Side portions 34 also include slots 47 for receiving a strap 46. Slots 47 are oppositely disposed on the upper regions 36 of side portions 34 as seen, for example, in Figures 2, 4 and 5 and are bounded by a beading 24.
  • Integrally molded beading 24 is formed along the periphery of mask piece 22 and around the edges of apertures 40 and 42 and slots 47 and serves to reinforce and to prevent breaking and cracking. Beading 24 also serves to reduce wear to strap 46 by the edges of slots 47. Beading 24 is preferably formed with a round cross section of approximately twice the average thickness of mask piece 22.
  • Strap 46 is fitted with a suitable closing means 48 which may be constructed in any conventional manner but preferably in a manner which permits strap 46 to be adjustable.
  • Strap 46 is illustrated as being formed as a single piece having two ends referred to as the first and second ends. A first end is inserted into a first slot 47 from the outside of mask piece 22 and is pulled through the first slot 47 to and through the opposite slot 47. The first end of strap 46 adjustably attaches to the second end of strap 46 to close strap 46 around the player's head.
  • Strap 46 may also comprise two pieces (not shown) having one strap piece attached to one slot 47, and a second strap piece attached to the opposite slot 47, whereby the free end of the first piece attaches to the free end of the second piece to close strap 46.
  • the closing means 48 for strap 46 permit the strap 46 to be opened, closed and adjusted in an easy and convenient manner, for example, through hook and loop means, e.g., a suitable hook and loop means such as that known in the trade and sold under the name VELCROTM.
  • hook and loop means e.g., a suitable hook and loop means such as that known in the trade and sold under the name VELCROTM.
  • Other means for releasably securing the face guard 20 to the player's head may be employed.
  • Front portion 26 of mask piece 22 includes an upper region 28 which is designed to shield the player's forehead area as best seen in Figure 7.
  • Upper region 28 includes a visor aperture 40, as seen in Figures 1-3 and 5-7.
  • Visor aperture 40 has an elongated curved oval shape and is bounded by the previously referred to beading 24.
  • a significant feature of the invention resides in visor aperture 40 being sized to accommodate the bill or visor of a cap, particularly of a standard, regulation baseball cap, and extends substantially the full width of front portion 26.
  • the player's cap visor shown in dashed lines in Figure 9
  • the player can wear a cap in its intended manner while wearing the face guard 20.
  • the cap visor when inserted into visor aperture 40 also has the effect of substantially stabilizing the face guard 20 on the player.
  • Vision aperture 42 shown in Figures 1-3 and 5-7, is provided in mask piece 22 to form an opening located in front of the eye area of the player when the face guard 20 is worn.
  • Vision aperture 42 is a generally oval shaped opening and is bounded by the previously described beading 24.
  • Vision aperture 42 extends substantially the full width of front portion 26 and has a lower edge 44 which dips to a point slightly above the tip of the player's nose to cover the player's nose.
  • Vision aperture 42 gives the player both unobstructed forward and peripheral vision. The player can thus see both to his right and to his left without turning his head from side to side.
  • a player playing short stop, for example, and wearing the face guard 20 can see the baseline without turning his head from side to side while also watching the batter.
  • distance D of vision aperture 42 ( Figure 2), gives the player the described unobstructed view and is narrow enough so that the ball is prevented from entering the vision aperture 42. So long as the player's view is not obstructed, distance D may be varied slightly according to the size of the ball or other play piece being utilized in the game.
  • a racquetball for example, may require a slightly narrower vision aperture 42 because a racquetball has a smaller diameter.
  • Upper region 28 of front portion 26 of mask piece 22 is also formed with a band portion 39 located below visor aperture 40 and above vision aperture 42.
  • Band portion 39 extends between integrally formed side portions 34 and gives front portion 26 structural strength.
  • Side portions 34 provide unbroken exterior side surfaces and form continuations of the generally outward curvature of the front portion 26 and assist in deflecting any ball hitting mask piece 22.
  • Band portion 39 is preferably formed with additional thickness (not shown) as compared to the other portions of mask piece 22 so as to give band portion 39 additional structural integrity.
  • Front portion 26 also includes lower region 32 designed to guard the player's nose, chin and throat areas. Integrally formed lower region 32 of the mask piece 22 extends between the side portions 34. As best seen in Figure 7, lower region 32 extends below the player's chin to cover the throat area and its outermost edge curves to follow the shape of the player's jaw line.
  • Mask piece 22 includes forehead pad 50 which is formed from a material which both provides cushioning and resilience.
  • a vinyl/nitrile blend of foam-like material has been found to be a suitable material for forehead pad 50 such as, for example, the material sold under the name RUBATEXTM by Rubatex Corporation of Bedford, Virginia.
  • Forehead pad 50 is secured to the inside surface area of upper region 28 of front portion 26, and covers substantially the entire inside surface area of the upper region 28, as seen in Figures 2, 4 and 5.
  • the forehead pad 50 absorbs and cushions the force of an impact and distributes the force throughout pad 50 and mask piece 22 such that the player is protected from the blow.
  • Forehead pad 50 may be adhered or otherwise secured to the inside surface of mask piece 22 by any conventional means which effectively secures pad 50 to mask piece 22 and such that pad 50 will not be dislodged in use.
  • An adhesive, or an adhesive tape, applied between pad 50 and the inside surface of upper region 28 has been found to be a suitable means for securing pad 50 to mask piece 22.
  • thickness T is sufficiently great so that no portion of the player's face protrudes from mask piece 22 either through visor aperture 40 or vision aperture 42. Additionally, thickness T is made sufficient to position the inner surface of mask piece 22 away from the player's face so that while wearing the face guard 20, a player can also comfortably wear eyeglasses without interference with the face guard 20 and without the glasses contacting the mask piece 22, as illustrated in Figure 7.
  • Mouth pad 52 is also included on front portion 26 .
  • Mouth pad 52 is secured to the inside surface of lower region 32 of front portion 26 and is centered below vision aperture 42 ( Figure 2).
  • the manner in which mouth pad 52 is secured to" mask 22, and the material from which the paid 52 is constructed, are similar to those applying to forehead pad 50 as previously discussed.
  • Mouth pad 52 is substantially oval in shape and covers a relatively large surface area of the inside surface of lower region 32. When face guard 20 is worn, the mouth pad 52 should substantially cover the player's mouth, and particularly the teeth. Mouth pad 52 is large enough so that an impact to the player's mouth area will be cushioned and distributed to minimize injury.
  • Teeth guard 66 is inserted into the mouth of the player and is placed between the player' s top and bottom teeth.
  • Plate 68 when worn, rests against the outside of the player*s mouth against the lip area and cushions the player's mouth and teeth areas upon the occurrence of impact or collision with face guard 20.
  • Stem 70 ( Figure 6) extends from plate 68 and tapers at its distal end to terminate with a knob 72 ( Figure 7).
  • Stem 70 of the invention represents a shortened version of the stem found in a conventional mouth guard.
  • Knob 72 and stem 70 are inserted into entrance end 58 and through corresponding channel 56. Knob 72 exits mouth pad 52 at exit end 60 and is inserted through mask piece opening 62, as shown in Figures 6 and 7. When mouth guard 64 is fully inserted into mouth pad 52, stem 70 resides within one channel 56. Knob 72 has a diameter larger than the diameter of channel 56 and mask piece opening 62 so that knob 72, once suitably placed, will secure mouth guard 64 in mouth pad 52 and to mask piece 22. Mouth pad 52, stem 70 and knob 72 are constructed from a material which is somewhat malleable so that knob 72 can be inserted through channel 56 and mask opening 62 which both have smaller diameters than the diameter of knob 72. Stem 70 is placed into the respective upper or lower channel 56 which best positions mouth guard 52 for the player at either a relatively high or low level in mouth pad 50. Having described the invention above in reference to the first embodiment, the description next proceeds to describe the second embodiment.
  • the face guard of the invention according to the second embodiment is illustrated in Figures 8-11.
  • the face guard has the major advantages of those of the first embodiment, and comprises a mask piece made of an open, easily ventilated, mesh comprising intersecting rod members forming the structure of the face guard.
  • the mask piece comprising the second embodiment face guard 80 is bordered by outer edge rod 82.
  • the visor aperture V is bordered by upper visor rod 83 and lower visor rod 84.
  • Vision aperture D is bordered by upper vision rod 86 and lower vision rod 88 with right and left sides bordered by vertical rods 96. It is understood that visor aperture V mates in size and shape that of a cap visor and vision aperture D is preferred to be large enough to provide the previously described front and side vision.
  • the rods may be of any cross sectional configuration, with round being preferred. It is generally preferred
  • the face guard rods be made of molded polycarbonate, but it is recognized that an alternate construction would be a metal wire matrix coated with a resilient material, such as a vinyl plastisol.
  • the mesh openings are all formed so as to prevent passage of the baseball, Softball or other play piece.
  • An enhanced and secure arrangement for releasably mounting the face guard of the invention to the head of the wearer comprises circumferential strap 100, top strap 102 and transverse strap 104 shown in Figure 9.
  • the straps 100, 102, 104 are formed so as to be individually adjustable to properly fit the wearer's head, and to permit donning and removing without having to open a fastening device.
  • the first or forward end of strap 102 is securely attached to outer edge rod 82 at the center of the top portion thereof.
  • the front or forward ends of strap 100 are securely attached to outer edge rod 82 at opposed edge portions essentially adjacent visor aperture
  • Strap 104 (see Figure 9) has a central portion securely attached to strap 102 and lateral side portions attached to strap 100.
  • the visor aperture V of the second embodiment is similarly adapted to allow the visor of a typical baseball cap
  • the overall shape of the face guard 80 is substantially the same in this second embodiment as in the first embodiment, allowing sufficient clearance so as to not contact parts of the wearer's face and being formed with a curvature to deflect an impacting ball.
  • a forehead pad 110 is attached to inner surfaces of the upper portion of face guard 80 and mouth pad 120 is attached to inner surfaces of the lower portion of face guard 80 as in the first preferred embodiment.
  • the means of connection of both forehead and mouth pads 110, 120 is portrayed in exploded view in Figure 11.
