TWO-WAY PROTECTIVE PAD CONSTRUCTION
A protective pad including a rigid shell bounded by a perimeter and a gasket engaging the perimeter so that forces applied to the shell are dissipated through the gasket before transferring to a wearer of the protective pad. The rigid shell cooperates with the gasket to provide a trampoline effect or two way spring. This effectively absorbs shock from forces generated by the opponent, so that the wearer and a colliding opponent both encounter reduced forces. The shell can bow outwardly to form a cavity above the wearer when the gasket is placed adjacent the wearer, which can prevent the rigid shell from bottoming out against the wearer upon impact. The protective pad can be implemented in a thumb protector including a stopper disposed between adjacent rigid shells covering proximal and distal portions of a digit. The stopper can engage the shells and effectively prevent hyperextension of the digit.

The present invention relates to protective equipment that shields forces, which are exerted on a wearer, and more particularly, to a multi-layered padding construction that provides minimal bulk and impediment to movement, yet maximizes protective coverage and protection to both the wearer, and optionally another person impacting the protective equipment.
Protective padding is used to protect its wearer from injury or from experiencing an impact due to applied forces. The increased popularity of physical sports has increased the need for personal protective padding. Sporting activities, such as hockey, lacrosse, baseball, basketball, football, soccer, biking, motorcycling and other activities all can lead to falls, collisions and impacts, which can cause pain, injury and damage to unprotected parts of the body.
Conventional protective padding, however, uses “one-way” padding constructions. This means they are primarily designed to protect the wearer of the padding. During a collision or check, the pad makes contact with an external object, for example, an opponent, another player, the ice, the ground, boards or another object. The padding typically includes a layer of plastic sandwiched between and directly contacting layers of foam. The padding helps reduce pressure on the wearer by distributing the impact force over a large area. The two foam layers act as a cushion and provide comfort; however, they frequently attain their compression limit, bottoming out and doing little to attenuate further transferred impact forces.
This usually is not much of an issue because injuries are the result of pressure. Pressure is a specific amount of force over a given area. Therefore, as the contact area increases, the pressure decreases, and so does the risk of injury. For the wearer of the protective padding during a collision, the impact is spread over a large surface due to the plastic layer. The plastic layer alleviates pressure from the wearer, for example, their appendages or joints, by deflecting impact energy toward the edge of the plastic layer. The wearer may feel the pressure from the impact, but it typically is not enough to cause injury.
The reason the present protective padding described above works for the wearer, is the same reason that it is ineffective for protecting opponents or other players during collisions with the wearer of the protective padding. When dealing with impacts and the related forces, a relevant axiom is that for every action there is an equal and opposite reaction. Conventional protective padding is frequently implemented in shoulder pad or elbow pad caps. Typically, these caps are rounded in contour. Usually, the surface of the object with which the cap collides—be it another player, person or object—many times is flat or convex. Accordingly, the force exerted by the cap on that surface is concentrated at a single point, which is usually a small contact area on the surface of the other player or person impacting the wearer of the protection padding. The foam, as mentioned above, does not provide much cushioning between the wearer and the other player or person, particularly where the force exceeds the compressive strength and the foam bottoms out. With this reduced shock absorption, the player or person impacting or being impacted by the wearer of the protective padding usually experiences a great deal of pressure in a very localized area. As a result, that other player or person can be injured by the impact, even though the wearer of the protective padding is not injured.
SUMMARY OF THE INVENTIONA protective pad is provided including a layered pad having a rigid protective shell joined with a base or gasket. The gasket, which optionally can be constructed from a high density compliant material, substantially surrounds and contacts the perimeter of the shell. The shell is elevated a distance above the base and/or the wearer, generally in a central region of the pad so that a cavity is formed therebetween. Forces generated from an impact with the pad and/or shell are transmitted primarily through the shell to the gasket, and from there to wearer's body. This can dissipate the impact forces, cushion the blow and absorb energy, thereby providing protection to the wearer, as well as the person or item impacting the wearer.
In one embodiment, the protective pad includes a rigid shell bounded by a perimeter and a gasket engaging the perimeter so that forces applied to the rigid shell are dissipated through the gasket. The rigid shell cooperates with the gasket to provide a trampoline effect or two way spring, which can protect both the wearer and the person or item impacting the wearer effectively absorbing the energy and/or dissipating the impact forces.
In another embodiment, the gasket can define an open gasket recess or ring, generally bounded by a boundary wall and a support shelf. The rigid shell perimeter can rest on the support shelf in the gasket recess. An outer edge of the rigid shell can be placed adjacent and/or abut the boundary wall.
In still another embodiment, the support shelf can be of a predetermined thickness and width to accommodate the perimeter and/or edge of the rigid shell, and effectively absorb shock generated by impacts to the rigid shell.
In yet another embodiment, the protective pad can include an inner layer, optionally constructed from low density foam. The inner layer can be configured to engage the wearer. The rigid shell can bow outwardly to form a cavity above the wearer, and generally between the shell and the inner layer, when the gasket is placed adjacent the wearer. The dimension of the cavity and distance from the inner layer and/or wearer can be preselected to prevent the rigid shell from bottoming out against the wearer upon impact.
In even another embodiment, the rigid shell and gasket, and optionally the inner layer, cooperate to ensure that impacts to the shell are spread over the entire surface of the shell, which in turn enables the shell to utilize more of the available gasket on the protective pad, thereby protecting both the wearer and an opponent engaging the wearer during the impact.
The protective pad herein is well suited for a variety of protective equipment, for example, shoulder pads, elbow pads, knee pads, shin guards, wrist pads, gloves, thumb protectors, digit protectors, leg pads, ankle pads and even body armor. Moreover, the protective pad described herein optionally can maintain pad weight in acceptable range, facilitate player movement, reduce the amount of plastic and shell size, increase impact time, and decrease impact pressure.
In a further embodiment the protective pad can be implemented in a thumb protector (which includes any protectors for the thumb and/or any digit) to both protect the wearer's digit from blows and to prevent hyperextension of the digit. In such a construction, the protective pad can include a proximal rigid shell and a distal rigid shell, separated by a gap. The shells can be further joined with a gasket assembly including a region of flexure. The region of flexure can be configured to overlap a joint of the user's digit.
In still a further embodiment, the thumb protector can include a separate and independent stopper disposed between the proximal and distal rigid shells. The stopper can be engaged by the respective proximal and distal rigid shells, thereby stopping movement relative to one another, and preventing hyperextension or overextension of a digit with which the protective pad is associated.
In still yet a further embodiment, the thumb protector protective pad can include a proximal rigid shell and a distal rigid shell, separated by a gap. The shells can be further joined with one or more gaskets. The shells and gaskets can be isolated or independent from one another, generally attached to a thumb or digit gusset, and independently moveable. The shells and gaskets can be configured to include the components of the other protective pads herein.

The protective pad 20 can include an outer layer, or a cushion layer 30. The cushion layer can be secured to a rigid shell 50 and/or a gasket 40. Generally, the outer layer or cushion layer can be constructed from a low density foam or other compliant material. By low density foam or low density compliant material, it is meant that the foam/compliant material has a density generally of about 0.02 grams per cm3 to about 0.09 grams per cm3, optionally, less than 0.07 grams per cm3, further optionally about 0.045 grams per cm3. The particular foam or compliant material can be constructed from low density ethyl vinyl acetate (EVA), polyurethane, or open pore polystyrene. The outer cushion layer 30 can be constructed from foams or other materials that deform under pressure, thus absorbing some of the force generated by an impact. As a result, the impact on the player transferred through the pad is lessened because of the deformation of the compressible material absorbing some of the overall shock of the impact.
The outer cushion 30 layer can generally be enveloped or covered with a covering. The covering can be a fabric, woven or non-woven, such as Lycra®, spandex, vinyl, polyester, nylon or some other generally soft, pliable lightweight material. Although not shown, the covering can be glued, stitched, cemented or otherwise secured with fasteners to the outer cushion layer. The outer cushion layer 30 can include a stitching channel 32 (
The outer cushion layer 30 can be of a predetermined thickness. This predetermined thickness can be a minimum thickness mandated by the particular rules of the sport in which the protective pad is used. As shown in
The outer layer 30 and any optional covering thereof can further be joined with the shell 50. The shell 50 can be constructed from a rigid or semi-rigid, self-supporting, generally slightly deformable materials such as high density polyethylene, polypropylene, polycarbonate, metals, laminates, polyesters and polyamide materials. Generally, the rigid shell can be a variety of thicknesses, for example, it can be about 0.5 mm to about 5 mm, optionally about 1 mm to about 3 mm and further optionally about 2 mm in thickness. Of course, the thicker the piece, the more weight that is added to the protective pad.
The shell 50 can generally be contoured so that it is of a relatively low profile and follows the contours of the body part which is designed to protect. The shell 50 generally can include a convex, exterior surface 52 and a concave inner surface 53. The shell 50 also can be constructed to be bounded by an outer edge 54. Depending on the particular configuration, the outer edge generally can conform to the boundary wall 42, also referred to as a “ring” of the gasket, as described further below. The shell 50 also can include a zone of engagement 56 which is the region around the perimeter 57 of the shell that engages the gasket 40 directly. More particularly, the zone of engagement 56 is a region where the interior surface, for example the concave angled or other interior surface 53 of the shell 50 engages or lays upon the support shelf 41 of the gasket 40. The zone of engagement 56 can extend about 3 mm to about 10 mm, or more inward from the outer edge 54. The zone of engagement is usually sized so that it fits substantially entirely within the ring or boundary wall 42 of the gasket 40.
Optionally, the zone of engagement 56 can be constructed so that it transitions to a stepped or angled portion 58 (
The shell can terminate at the shell edge 54. The shell edge can correspond closely to the edge 37 of the overlying cushion or outer layer 30. Indeed, the two elements can be coterminous so that they closely fit adjacent or abut the boundary wall 44.
Referring to
As shown in
Generally, the pad 20 can include the inner layer or liner 60. This inner layer 60 can be constructed from a low density compliant material, such as a low density foam. This low density foam or low density compliant material can be an EVA or polyurethane foam generally ranging in density from about 0.03 grams per cm3 to about 0.9 grams per cm3, optionally about 0.045 grams per cm3. The inner layer can have a durometer of about 55 Shore OO. The inner layer can be joined with the gasket 40 and positioned adjacent a lower surface 46 of the gasket. This inner layer 60 can be of any desired thickness, for example, it can be about 1 mm to about 15 mm, 2 to about 10 mm, and optionally about 6 mm in thickness. The thickness can be uniform across the entire layer, or the thickness can follow the contour of the gasket to reduce in bulk and improve upon pressure distribution.
Optionally, the inner layer 60 can be of a laminate construction with a fabric covering its interior and exterior sides. The fabric can be Lycra®, or any other suitable fabric for engagement against a wearer's skin or clothing. As shown in
Turning now to
The support shelf 41 of the gasket 40 generally is transversely oriented, for example, perpendicular to, the boundary wall or ring 42. The boundary wall 42 can extend upwardly from the support shelf 41 to the upper surface 45 of the gasket 40. At the transition from the boundary wall 42 to the upper surface 45, the boundary wall can be rounded for a gentle transition to the upper surface. Indeed, the entire ring or boundary wall 42 can be of a generally rounded or angled configuration from the shelf to the upper surface if desired. Optionally, the support shelf can transition from a first, lower level, upward to a second higher level of the upper surface via the boundary wall. The upper surface 45 can extend outwardly, away from the boundary wall 42 so that it does not overlap or extend over the support shelf.
The support shelf 41, as shown in
The support shelf 41 can be of a predetermined thickness D9 (
As shown in
The gap D3 (
The gasket 40 optionally can be constructed to have a margin 47 that extends around the gasket from the boundary wall 42 to the outer edge 49A of the gasket. This margin 47 can generally be referred to as the outer width of the gasket surrounding the shell 50. As shown in
Generally, the gasket 40 can be constructed from a high density compliant material. The high density compliant material can be foam, such as expanded polypropylene foam, ethyl vinyl acetate (EVA), polyurethane, or open pore polystyrene or other foams, thermoplastic polyurethane, gels and the like. By high density compliant material or high density foam, it is meant that the material/foam has a density generally of about 0.05 grams per cm3 to about 0.30 grams per cm3, optionally, greater than 0.05 grams per cm3, further optionally greater than 0.10 grams per cm3, even further optionally about 0.15 grams per cm3 or greater, depending on the application.

Another embodiment of the protective pad is shown in
Generally the gasket 240 can be substantially similar to the gaskets 40 and 140 above. The shell 250 can be separated into first shell portion 250A and second shell portion 250B. The first shell portion 250A can also be referred to as the proximal shell portion while the portion 250B can be referred to as the distal shell portion. The shells making up these portions can be substantially identical to the other shells described in connection with the other protective pads herein. Generally the distal shell portion 250B can be configured to cover and provide protection for the distal phalanx while the proximal shell 250A provides protection for the proximal phalanx. Each of the respective proximal and distal shells 250A and 250B can include the interior and exterior surfaces. The interior surface 253 can be generally concave. The shells can also include an outer edge 254 like the other pads noted above.
The gasket 240 can be similar to the gaskets of the embodiments above with several exceptions. For example, the gasket 240 can include a support shell or portion 241 that is bounded by a boundary wall or ring 242. The boundary shell in this embodiment, however, can extend entirely under respective proximal and distal shell portions 250A and 250B so that the inner surfaces 253 thereof are in contact with the shell 241 across substantially all the underside of the respective shell portions. Of course, however, there can be gaps established between the interior surface 253 and the support shell 241 in particular locations are desired.
The forward edge 256A of the proximal shell portion 250A and the rear edge 256B of the distal shell 250B can be however unbounded by the boundary wall or ring 242. Generally as shown in
Returning to the gasket 240 shown on
One exception is that the base 245 can include a zone or region of flexion. Within the zone or region of flexion, a stopper 280 can be located. The zone of flexion can include one or more gaps 248A that are established between the stopper 280 and in particular the proximal 256A and distal 256B surfaces of the stopper 280, relative to the edges 241A and 241B. These gaps can be anywhere from 0.01 m to 2 mm, or other distances depending on the particular application. The gaps can extend from a lateral side of the gasket 240 to a medial side of the gasket 240. The zone of flexion can allow the portion of the gasket 240 associated with the proximal shell 258 to flex or move about the region of flexion 248 relative to the portion of the gasket associated with the distal shell 250B. Generally there is no fixed pivot in the region of flexion 248, rather the shell can flex somewhat dynamically in multiple different locations of the gasket, particularly in the margin 247. Without a designated, specific point of pivot, the thumb protector can accommodate a variety of different length and oriented and configured thumbs of a variety of different wearers.
The zone of flexion 248 as shown above also can be joined with the stopper 280. Again the stopper can be constructed monolithically from a single piece construction with the remainder of the gasket 240. The stopper 280 can extend from the margin 247 on a medial side of the thumb protector pad to a lateral side of the protector pad. The stopper itself can include an exterior surface 283 and an interior surface 284 opposite the exterior surface. Generally the interior surface 284 can be flush with the interior surface of the remainder of the gasket while the exterior surface 283 can be flush with and/or extend above the proximal 250A and distal 250B shells.
The stopper is illustrated in
In operation, the thumb protector 220 can operate to prevent hyper or over extension of the digit, for example the thumb, in which the thumb protector is implemented. For example, as shown there, the thumb protector is shown in a partially flexed state in solid lines. In that configuration, a first gap G1 is established between the edge 256B of the distal shell 250B and the front or forward surface 281 of the stopper 280. Further, a second gap is optionally established between the forward edge 256A of the proximal shell 250A and the rear surface 283 of the stopper 280. The gaps 248A and 248B respectively open up between the portions of the gasket adjacent the stopper 280.
When the thumb, however, is forced rearwardly in the direction of the arrows as shown toward a hyper extended or over extended state, the gap G1 and optional gap G2 are closed so that the respective edges 256B contacts the surface 281 of the stopper 280 and the edge 256A contacts the rear surface 283 of the stopper 280. This collision or engagement of the respective proximal and distal shells 250A, 250B of the stopper surfaces stops or impairs the rearward motion of the digit within the glove to which the protective pad 220 is associated so that that digit does not hyperextend. The forces of the edges impacting the surfaces of the stopper 280 can also be transmitted through these proximal and distal shells to the respective boundary walls 242 to further decrease the likelihood of hyper extension.

The distance D6 can be substantially greater than the distance D8 (

Another difference between the cushion layer 130 of this embodiment and the embodiment above concerns the edges or perimeter of the that layer. For example, as shown in
Another embodiment of the protective pad is shown in
The protective pad can be incorporated into a finger or thumb portion of a protective glove 202. The protective pad 220 can be attached to the finger portion or thumb portion using any conventional means, for example, via stitching, gluing, adhering, radio frequency welding and/or fastening. The protective pad 220 can include a gasket 240 and rigid shell 250. The gasket 240 can be joined to one or more inner layers (not shown) which are further attached to the finger or thumb portion 202 of the glove.
The gasket 240 can be substantially similar to that of the gaskets 40 and 140 above. The shell 250 (
Generally, the distal shell portion 250B can be configured to cover and provide protection for the distal phalanx while the proximal shell 250A can be configured to cover and provide protection for the proximal phalanx. Each of the respective proximal and distal shells 250A and 250B can include interior and exterior surfaces. The interior surface 253 of each can be generally concave. The shells each can also include an outer edge 254 like the other protective pads in the embodiments above.
The gasket 240 can be similar to the gaskets of the embodiments above with several exceptions. For example the gasket 240 can include a support shelf or portion 241 that is bounded by a boundary wall or ring 242. The boundary shelf in this embodiment, however, can extend entirely under the respective proximal and distal shells 250A and 250B so that the inner surfaces 253 of the shells thereof are in contact with the shelf 241 across substantially all the underside of the respective shells 250A and 250B. Optionally, gaps or cavities can be established between the interior surface 253 of the shells 250A and 250B and the support shelf 241 in particular locations as desired.
The forward edge 256A of the proximal shell 250A and the rear edge 256B of the distal shell 250B can be unbounded by the boundary wall or ring 242. As shown in
Returning to
One exception is that the base 245 can include a zone or region of flexion 248. Within the zone or region of flexion, a stopper 280 can be located. The zone of flexion, and more generally, the gasket 240, can include one or more gaps 248A and 248B established between the stopper 280, and in particular, the proximal 281 and distal 282 surfaces of the stopper 280 relative to the edges 241A and 241B of the shelf or gasket. These gaps can be anywhere from 0.01 mm to 2.0 mm, or other distances depending on the particular application. The gaps can extend from a lateral L side of the gasket 240 to a medial M side of the gasket 240. The zone of flexion can allow the portion of the gasket 240 or base 245 associated with the proximal shell 250A to flex or move about the region of flexion, and/or relative to the portion of the gasket 240 or base 245 associated with the distal shell 250B.
As illustrated, there is no fixed pivot in the region of flexion 248, rather the shell flexes generally dynamically, in multiple different locations of the gasket, particularly in the margin 247. Without an isolated and specific pivot point, the thumb protector can accommodate a variety of different length and configured thumbs or digits to accommodate multiple users. Optionally, if desired, the zone of flexion can be replaced with one or more dedicated pivot points, with the gasket parts or shell connected via one or more pins or fasteners.
The zone of flexion 248 as shown above also can be joined with the stopper 280. The stopper 280 can be constructed with the remainder of the gasket 240, monolithically from a single piece construction. The stopper 280 can extend from the margin 247 on a medial side M of a protective to a lateral side L of a protective pad. The stopper itself can include an exterior surface 283 and an interior surface 284 opposite the exterior surface. Generally, the interior surface 284 can be flush with the interior surface of the gasket, while the exterior surface 283 can be flush with and/or extend above the proximal shell 250A and distal 250B shell.
The stopper 280, as illustrated in
In operation, the thumb protector 220 can operate to prevent hyper or over extension of a thumb or digit. As shown in
When the thumb is forced rearwardly in the direction of the arrows as shown, toward a hyperextended or overextended state, gap G1 and gap G2 are closed so that the distal shell and its edge 256B contacts the distal surface 282 of the stopper 280, and the proximal shell and its edge 256A contacts the proximal surface 281 of the stopper 280. This collision or engagement of the respective proximal and distal shells 250A, 250B with the stopper surfaces stops or impairs the rearward motion of the digit within the glove, so that digit is not hyperextended. The forces of the edges impacting the surfaces of the stopper 280 can also be transmitted through these proximal and distal shells to the respective shelf 24 and/or boundary walls 242, as well as the margin and gasket in general (as discussed with the other embodiments herein), to further decrease the likelihood of hyperextension.
Optionally, the protective pad in the thumb protector described immediately above can be modified so that the respective gaps 248A and 248B of the gasket 240 are eliminated. In this construction, the proximal and distal shells 250A and 250B, and in particular the edges 256A and 256B, can rest immediately adjacent and/or in contact with the stopper 280. In this construction, the protective pad operates similar to the protective pads of the other embodiments herein. The shells and the boundary walls 242 as well as the shelf 241 operate and transmit forces similar to the other protective pads described herein. Further optionally, the thumb protector described immediately above can be modified so that it is more of a fixed nonmoving non-flexing construction with a unitary rigid shell. For example as shown in
The thumb protector 320 can also optionally include a cavity defined between the interior of the shell 350 and the shell 341 or generally the gasket 340. Further optionally, the shell 350 can be supported by a support ridge or projection 345 and this projection 345 can extend upwardly from the casket 340 as shown. The shell can include a recess or other area 352 configured to interact with and/or engage the ridge 345 effectively, the ridge, recess or area 352 of the shell 350. This can provide additional optional support, enforce transmission capabilities of the protective pad 320.
A method for assembling the protective pad of the embodiments above will now be described. To begin, the gasket of the protective pad can be compression molded to obtain a desired shape. The gasket may or may not be lined with a material for cosmetic purposes. If it is, the material can be sewn, glued, radio frequency welded or otherwise attached to the outer surfaces of the gasket. The rigid shell material is molded, optionally injected molded, and cut to the desired dimensions. It can be covered with an outer protective layer or foam as described above, and an inner lining if desired as well. These components can be held together with an adhesive cement or other fastening mechanism. The shell, along with the outer cushion layer and optional lining cover can be sewn to the gasket along the inner edges or in the zone of attachment and/or the ring. With these components constructed, the inner layer or liner, which also can be lined with a material as described above, can be added to the underside of the gasket and stitched together along an outer perimeter. If desired, the nylon binding can be added to the edge of the gasket and inner layer to conceal the junction and interface between these elements.
The protective pad of the current embodiments can be used to attenuate forces or absorb shock caused by a person or player applying a force via impact to a wearer of a protective pad. Generally, in use the method includes the wearer donning the protective pad. For example, with reference to
The gasket and shell effectively cooperate to absorb the shock generated by the applied force. It can be said that these elements generally provide a trampoline effect or two-way spring effect so that the wearer and the colliding opponent both encounter a reduced amount of force. Further, the effective duration of the forces and impact exerted on the wearer, and likewise felt by the opponent contacting the protective pad is spread out over a greater amount of time, which in turn causes a decrease in the peak force felt by the wearer and the opponent.
As an example, reference is made to
In effect, the protective pad of the embodiments herein accomplishes two things. First, it slows down the impact and thereby provides a cushion to the impact. Second, it also provides a means to absorb the impact energy, and thus provide shock absorption. Generally, the cushioning relates to the amount of deceleration during impact or how much the impact is slowed which is typically measured in units of gravity (Gs). The shock absorption is the amount of energy absorbed by the material, and in this case, by the combination of the outer cushion layer, the shell and the gasket. The gasket, when constructed from higher density compliant materials such as foams or other materials can absorb even more impact energy.
To test the efficiency of the protective pad of the present embodiments, two basic shoulder caps were constructed. The first was a conventional shoulder cap construction including a first outer layer of soft EVA foam, an inner or second layer of soft EVA foam, with a plastic shell sandwiched therebetween, with no space between the foam and the plastic. The second protective pad was constructed like that shown in
The protective pad of the current embodiments repeatedly performed better than the conventional pad in two ways. First, the impact duration was increased as shown in
As shown in
The protective pad may be used in many applications, such as in athletic gear and apparel, protective clothing and protective barriers. Objects that may be protected using an item comprising a protective pad of the current embodiments include all parts of the human body such as the elbows, shoulders, head, neck, arms, wrist, hands, thumbs, digits, chest, torso, groin, legs, back, buttocks, knees, shins, ankles and feet. Items that may comprise the protective covering include shoulder pads, elbow pads, helmets, neck braces, wrist pads, gloves, thumb protectors, body armor, shoes, body garments, leg pads, knee pads, shin pads, ankle pads and jackets. Any athletic gear and apparel, protective clothing or protective barrier known in the sports and industrial protective covering industry may be protected.
