Embodiments of the invention are generally related to devices for protecting the wearer's head from impact and protecting others from the wearer's head. Embodiments are capable of being used for many different sporting activities, including those that take place in or out of the water.
Although various types of protective sports headgear are known, there remains a need for improved protective sports headgear. Concussions and other head injuries are problematic in a multitude of sports. Additionally, there are many sports where it is not practical for one to wear a bulky or heavy helmet.
In the sport of water polo, the headgear that is traditionally worn by players provides very little to no protection for the wearer. Water polo is a contact sport, and concussions and head injuries occur with some frequency. Additionally, the traditional headgear is not buoyant and may sink to the bottom of the pool where a water polo match is being played if it is knocked loose.
The systems, methods and devices of the disclosure each have several innovative aspects, no single one of which is solely responsible for the desirable attributes disclosed herein.
According to one embodiment, a protective sports headgear device includes: an inner layer of material which includes a first side which contacts a wearer's head and a second side which contacts at least one layer of padding material; an outer layer of material has an internal side which contacts the at least one layer of padding material and an external side that provided the outer surface of the headgear device; and an edge seals the inner layer to the outer layer so they are joined together such that the at least one layer of padding material is retained within the inner layer and outer layer material.
According to one embodiment, a protective sports headgear device includes at least one layer of covering material and at least one layer of padding material wherein the at least one layer of padding material is composed of a plurality of panels, wherein each panel is connected to at least one other panel.
According to one embodiment, a protective sports headgear device includes at least one layer of covering material and at least one layer of padding material, wherein the covering material is configured to substantially surround at least one of the larger faces of the padding material, and wherein both the padding material and the covering material are configured to substantially cover a human head when in use.
According to one embodiment, a method is provided for manufacturing a protective sports headgear device. The method includes providing a padding material formed from a plurality of individual padding panels that are affixed to one another; providing an inner covering material and an outer covering material, where each of the covering materials have edges, combining the inner covering material, the padding material and the outer covering material together; and joining the edges of the inner covering material and the edges of the outer covering material such that the padding material is retained between layers of inner covering material and outer covering material.
These figures are provided for illustrative purposes and the embodiments are not limited to the specific implementations illustrated in the figures.
Any feature or combination of features described herein are included within the scope of the present disclosure provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this description, and the knowledge of one skilled in the art. In addition, any feature or combination of features may be specifically excluded from any embodiment of the present disclosure. For purposes of summarizing the present disclosure, certain aspects, advantages, and novel features of the present disclosure are described herein. Of course, not necessarily all such aspects, advantages, or features will be present in any particular embodiment of the present disclosure.
Embodiments presented herein are by way of example and not by way of limitation. The intent of the following detailed description, although discussing exemplary embodiments, is to be construed to cover all modifications, alternatives, and equivalents of the embodiments as may fall within the spirit and scope of the disclosure.
One embodiment relates to a protective sports headgear device for water sports, such as water polo. The headgear device may be shaped similar to a conventional water polo cap, but include at least one layer of padded material within the device. For example, one embodiment of a protective sports headgear device may be suitable for wearing on a person's head while that person is engaged in the sport of water polo, wrestling, or other sports. The protective sports headgear device can include an inner covering layer that directly contacts the head of the wearer and an outer covering layer that can be made from a variety of fabrics, including a blend made from polyester and polybutylene terephthalate (PBT). Additionally, the outer covering layer may incorporate decorative designs, team logos, or player numbers.
Embodiments of the protective sports headgear device can further include one or more inner layers of a material or materials that reduce, dampen, or disperse impact forces acting on the head of the wearer. The inner layers may also reduce, dampen or disperse impact forces delivered by the head of the wearer against other individuals. This force reduction, dampening, or dispersion may be accomplished by an inner layer of material that reduces the maximum force felt by the wearer's head during a collision with another body or object. Such material may work by spreading out the applied force over a longer duration than if the collision had taken place without the headgear. Alternatively, this reduction or dispersion of force can be accomplished by a material which spreads the force out over a larger area than if the collision had taken place without the headgear, thereby reducing the maximum pressure asserted on the head at a specific point. This force reduction, dampening, or dispersion can also be accomplished through a rate-dependent, or viscoplastic, material that adapts to different types of impacts.
By reducing, dampening, or dispersing impact forces imparted onto the wearer's head, embodiments of the protective sports headgear device may reduce the risk of head injuries sustained by the wearer. The protective sports headgear device may also reduce the risk of concussions sustained while engaged in various sports by further protecting the wearer's head from various sports traumas. Embodiments may be especially useful in water polo where head injuries are prevalent due to the lack of protective headgear that works efficiently in the water and complies with various rules regarding allowable headgear. Water polo is a sport where heavy or cumbersome headgear is problematic due to the fact that players must constantly support their own weight in the water by treading water. Thus, heavy headgear may weigh a player down, causing the player to have to expend much more energy to stay above water. Further, if headgear is loose-fitting or cumbersome, the headgear can get in the way of the water polo player because the player needs to be able to put their head underwater at times and move underwater with ease. If headgear is loose-fitting or cumbersome, it can create a lot of drag when a player tries to make quick movements in the water. Additionally, a loose-fitting headgear can create a lot of resistance for a player putting their head underwater due to the concave shape of the headgear acting as a parachute of sorts and quickly filling with water. Moreover, traditional protective sports headgear such as helmets may contain parts that are susceptible to corrosion when regularly exposed to water and chlorine.
In some embodiments, the protective sports headgear device may be made to be buoyant so it can float on the surface of the water when not being worn. Traditional water polo headgear is not buoyant and may cause a player to lose their cap during a match if the cap sinks below the water's surface. Embodiments of the protective sports headgear device may be constructed from different buoyant materials which can prevent the headgear from sinking in water. Some embodiments of this protective sports headgear device will balance buoyancy with drag and resistance to entering water. Some embodiments will focus on one characteristic over the others or will try to optimize all characteristics. However, some of these characteristics may not be present or may be de-emphasized in some embodiments.
The padding material 13 can be disposed somewhere between the outer covering material 12 and the inner covering material 11. However, there can also be embodiments where there is only one of either the outer covering material 12 or the inner covering material 11. In such embodiments, the padding material 13 can be disposed on either side of the covering material and can either be the outer layer or the inner layer. In some embodiments, the protective sports headgear device 10 may cover more of the wearer's forehead region than traditional water polo headgear. This may allow the protective sports headgear device 10 to protect more of the wearer's forehead. This may also help protect other players from injury due to contacting the wearer's forehead.
In one non-limiting embodiment, the outer covering material 12 of the protective sports headgear device 10 will, together with the inner covering material 11, surround and encompass the padding material 13 of the headgear. The outer covering material 12, the inner covering material 11, and the padding material 13 can be formed in a substantially hemispherical shape that generally conforms to the shape of a human head. The outer covering material 12 may be composed of a substantially soft or pliable material in order to mitigate the force applied by the headgear to another body or object in the case of a collision between the head wearing the headgear and a body or object. A person of skill in the art will recognize that the outer covering material 12 of the protective sports headgear device 10 may be made from any number of materials, including but not limited to, polyesters, soft or hard plastic, a rubber, nylon, lycra, neoprene, or some other natural or synthetic material or some combination thereof. In some embodiments, the outer covering material 12 may be made of more resilient materials such as hard plastics or metals. Additionally, a set of ear-guards 20 can be provided on both sides of the headgear. These ear-guards 20 can protect the wearer's ears from trauma caused by elbows, hands, heads, sports balls, or any other type of object or body-part that could otherwise contact the ears if it were not for the ear-guards 20. The ear-guards 20 will be discussed more below with respect to
The padding material 13 layer may be composed of a substantially smooth surface with a plurality of raised surfaces (not shown) disposed on the smooth surface. These raised surfaces may be similar to small plateaus that are arranged in a pattern over one surface of the padding material 13 layer. The raised pad surfaces can be shaped and arranged to allow the padding material 13 layer, and therefore the protective sports headgear device 10, to more easily flex, bend, fold, stretch, or to conform to the wearer's head. The raised pad surfaces can also be in the form of ridges. Further, the raised pad surfaces can provide for a padding material 13 layer that uses less material but still provides substantially the same protection and cushioning. These raised surfaces or ridges also may not be of the same height as all the other raised surfaces or ridges. Thus, in some embodiments, these raised surfaces or ridges result in a raised surface of variable thickness relative to the substantially smooth surface. In other embodiments, the substantially smooth surface may be replaced with a surface that is not substantially smooth and has valleys or cuts formed in it. Thus, there may be a surface that has both raised ridges formed on it and valleys formed into it. These embodiments can provide for less material in the places that need to flex, bend, fold, stretch, or conform to the wearer's head more without sacrificing too much padding material.
The padding material 13 layer may contain a bladder or other fluid retaining portion so that at least part of the padding material 13 layer can be filled with fluid. This can also be accomplished by having two layers of padding material, where one of those layers is capable of being filled with and retaining a fluid. The fluid-filled padding layer/portion can provide for a better fit by adjusting the amount of fluid in the fluid-filled padding layer or portion. Additionally, the fluid-filled padding layer/portion can provide additional padding that helps to dissipate, dampen, or disperse forces caused by collisions. One of skill in the art will appreciate that the fluid-filled padding layer/portion can be filled with a variety of different gasses and liquids, including but not limited to, air, water, or some other specific liquid or gas or combination of fluids that have desirable properties.
Additionally, any one or multiple of the layers may include a waterproof or protective coating. One of skill in the art will appreciate that this coating may be applied by using a spray, powder coating, paint, or some other application method or combination thereof. The waterproof or protective coating can help prevent corrosion or degradation of any of the materials that may occur due to exposure to water, chlorine, or other chemicals.
In certain embodiments, one or more layers of padding material 13 may be made from a buoyant material. This buoyant material can help the entire headgear to float in water. Thus, if the protective sports headgear device is dislodged during play, it will remain floating in the water so that it can be easily retrieved by a player. The padding material 13 and the covering materials can be formed and cut such that they generally conform to the shape of a human head. One of skill in the art will appreciate that this headgear can be made with many different cuts and dimensions in order to fit various sized heads.
Additionally, in some embodiments, there may be another layer of padding material 13 disposed between the plastic layer 14 and the outer covering material 12 layer. This additional layer of padding material 13 could provide the added benefit of having additional padding which could additionally reduce an impact force felt by the wearer of the protective sports headgear device 10. Further, layering rigid materials with soft materials can provide for additional and predetermined force-dampening properties. Providing additional layers of padding or material may be used to surround or encapsulate the plastic layer so that is can provide protection for a user, but still be comfortable and safe for sports play.
One of skill in the art will appreciate that many different designs incorporating different numbers or configurations of padding panels will be appropriate to fit different sizes and shapes of heads. In certain embodiments, the protective sports headgear device 10 may be specifically tailored to fit one person's head or a small group of people's heads which may require a much more specific design that does not need to be as adaptable. On the other hand, it may be advantageous to have a protective sports headgear device 10 that can fit over as broad a range of heads as possible, in which case, the padding panel design of the protective sports headgear device 10 would need to be highly adaptable. Furthermore, it may be advantageous to use a padding panel configuration such that the protective sports headgear device 10 could be used by dogs or pets to reduce the risk of head injury. It may also be advantageous to form the padding 13 layer for the protective sports headgear device 10 out of a small number of panels or even a singular piece of padding for ease of manufacturing or to reduce costs associated with production. In certain embodiments, the protective sports headgear device 10 comprises a small number of panels or single panel of padding where those padding panels are themselves formed to match the shape of a person's head through 3d-printing or some other automated method of forming padding panel shapes that are more specialized than cutting shapes from a sheet of padding. Additionally, for each number of panels, there can be a variety of different corresponding designs. For example, although
The joints 121 can use a variety of different types of connectors, including but not limited to, stitching, adhesive, elastic connections, rigid connections, bonding, liquid seams, any combination thereof, or any other method of joining two materials. The joints 121 function as connections between the padding panels 113A-G. The joints 121 can be flexible, or the joints can also be rigid to provide more structure and support for the protective sports headgear device 10.
Although
The protective sports headgear device 10 can be created through a method of manufacturing that involves creating a layer of padding material from individual padding panels and connecting those panels by joints. This method of manufacturing the protective sports headgear device can allow for a manufacturing process that is more adaptable than other manufacturing processes. In this way, many different sizes and shapes of protective sports headgear devices can be created without as much lost time or extra costs as would be associated with other methods of manufacturing.
In certain embodiments, the protective sports headgear device comprises ear-guards 20.
An embodiment of a protective sports headgear device 10 that includes goggles 31 is advantageous because goggles 31 can protect the wearer's eyes. Goggles 31 can further provide protection from the harmful rays of the sun as well as provide prescription vision correction where it is otherwise impractical to wear glasses, such as while playing water polo. This inventive design provides a way for the wearer to wear goggles 31 as part of their protective sports headgear without having to worry about the goggles 31 slipping or falling off and sinking to the bottom of the pool. The goggles 31 may be secured to the protective sports headgear device 10 through many different ways, including but not limited to, clips, Velcro, fasteners, buckles, buttons, slots formed in the peripheral sides of the protective sports headgear device 10, or slots formed in the ear-guards 20, or any combination thereof or a variety of other ways. Additionally, the protective sports headgear device 10 can include one, both, or neither of the facemask 30 or goggles 31.
In embodiments where the padding material is not made from a buoyant material, other parts of the protective sports headgear device may be made from a buoyant material such as the covering materials, the ear guards, the ties, the joints, or the hem. In embodiments where the ties are buoyant but the rest of the protective sports headgear device does not float, the ties can remain above the surface while the rest of the protective sports headgear device acts as an anchor. Additionally, in embodiments where neither the protective sports headgear device nor the ties are made out of a buoyant material, buoyant attachments may be added to the ties. These attachments can aid players in visually locating dislodged protective sports headgear devices and could be similar to fishing bobbers. In these embodiments, the protective sports headgear device may not be as susceptible to being pulled into a gutter in a pool by water currents while still being able to be seen and retrieved by the players.
In other embodiments where the protective sports headgear device does float, there may be attachments added to the ties that are dense enough to be substantially not buoyant and act as anchors for the ties. These anchors can help prevent the protective sports headgear device from being pulled into a gutter in a pool by water currents while the protective sports headgear device is still able to float and therefore be seen and retrieved by the players. In many of these embodiments, the protective sports headgear device can also resist being pulled into a gutter by water currents due to its convex shape combined with the ties/attachments helping to keep a substantially open shape about the headgear. This open convex shape can act to resist movement through water, where for example, there is a current pulling the ties/attachments but not affecting the rest of the protective sports headgear device in the same way.
A person of skill in the art will recognize that the buoyant materials herein could encompass many different materials, including but not limited to, EVA foams, polyethylene foams, polyurethane foams, urethane foams, polystyrene, other closed-cell structure foams, and other materials, polymers or composites, or a combination thereof. Additionally, the term buoyant material can also be used to describe combinations of materials or layers or portions of materials that together achieve buoyancy. For example, although a certain plastic may not be buoyant itself, when it is formed as a pocket that is filled with air, the pocket may then become buoyant. Thus, for simplicity, the term buoyant material may be used to describe combinations of materials or layers or portions of materials such as this pocket.
As shown in
It should be understood that this arrangement of pads is not the only possible arrangement, and that the padding panels 213C and 213D can begin or end either closer to the anterior or posterior of the device in other embodiments. For instance, the right panel 213A can substantially cover the right side of a person's head, or the left panel 213B can substantially cover the left side of a person's head. In certain embodiments, the first center panel 213C can substantially cover the top, anterior portion of a person's head. In certain embodiments, the second center panel 213D can substantially cover the top, posterior portion of a person's head.
In certain embodiments, the protective sports headgear device 210 comprises the gap 215 disposed between the first center padding panel 213C and the second center padding panel 213C. In certain embodiments, the gap 215 acts as a shape accommodation portion that can expand, contract, or otherwise shift or transform in order to allow the headgear device 210 to accommodate heads of different shapes and sizes. The gap 215 can be a space or opening between padding panels. In some embodiments, the gap 215 does not comprise a gap in fabric or covering materials. That is to say, in certain embodiments, there may be covering material or fabric surrounding the gap 215. The gap 215 can allow the padding panels 213C and/or 213D to move in relation to one another. For example, the gap 215 may allow the padding panel 213D to move backwards and/or upwards to accommodate the shape of the wearer's head. In certain embodiments, the gap 215 allows padding panel 213D to move backwards and/or upwards to accommodate long-hair that is held behind the head. The gap 215 can allow the protective sports headgear device 210 to accommodate long-hair that is held in a swim cap at the back and/or top of the wearer's head. The gap 215 can allow the protective sports headgear device 210 to accommodate a variety of shapes of heads. In certain embodiments, the gap 215 can increase in size when the wearer puts the protective sports headgear device 210 on their head. In certain embodiments, the fabric surrounding the padding pieces 213A-D can stretch to allow the padding pieces 213A-D to move in relation to each other.
In an alternate embodiment, the gap may be a shape accommodation portion that is filled with an elastic material. In this embodiment the back end of the first center padding panel is connected to the front end of the second center padding panel through a stretchable or elastomeric material that allows the two center padding panels to move in relation to one another. In certain embodiments, the elastic material may allow the first center padding panel to move backwards and/or upwards to accommodate the shape of the wearer's head. In certain embodiments, the substantially elastic material allows the second center padding panel to move backwards and/or upwards to accommodate long-hair that is held behind the head. The substantially elastic material can allow the protective sports headgear device to accommodate long-hair that is held in a swim cap at the back and/or top of the wearer's head by stretching over the bulk caused by the hair. In certain embodiments, the substantially elastic material can increase in a length or width dimension when the wearer puts the protective sports headgear device on their head. In certain embodiments, the fabric surrounding the padding pieces may also stretch to allow the padding pieces to move in relation to each other.
In another embodiment, the shape accommodation portion can comprise an overlap between the first and second center padding panels. In this embodiment, a portion of the back of first center padding panel can overlap a portion of the second center padding panel. Alternatively, a portion of the front of the second center padding panel can overlap a portion of the first center padding panel. This overlap can allow the padding panels to move relative to one another when the wearer places the protective sports headgear device on their head. The overlap between the center padding panels can allow the protective sports headgear device to stretch and expand to accommodate for various head/hair sizes and shapes. The overlap can allow the headgear device to stretch and expand with minimal to no gap between padding panels. In this way, the overlap between the center padding panels can provide increased protection.
In another alternate embodiment, the protective sports headgear device comprises a hole or aperture in the accommodation portion that allows the wearer to put their hair through the hole. In this way, the hole or aperture can allow the protective sports headgear device to accommodate wearers with long hair. The hole or aperture can also allow the protective sports headgear device to expand or contract in certain directions to accommodate different sized heads. In certain embodiments, the headgear device comprises multiple holes or apertures. The multiple holes or apertures can allow the protective sports headgear device to expand or contract in certain directions to accommodate different sized heads. The multiple holes or apertures can also allow for venting or air flow through the protective sports headgear device.
In still another embodiment, the protective sports headgear device can comprise removable and/or replaceable padding panels. In some embodiments, the hem of the protective sports headgear device comprises at least one separable portion, which can be separated by the wearer with a reasonable amount ease. This separable portion can comprise Velcro, hooks and loops, snaps, or some other means of fastening two fabrics together. A user can separate this separable portion such that there is a portion of the outer covering material that is not connected to the inner covering material. In certain embodiments, the stitching between panels can comprise at least some separable portion which can be separated by the wearer with a reasonable amount ease. This separable portion can comprise Velcro, hooks and loops, snaps, or some other fastening component or components. A user can separate this separable portion such that there is a portion of the outer covering material that is not connected to the inner covering material. In certain embodiments, the protective sports headgear device can comprise a pouch. The pouch can be a pouch formed by the inner covering material and outer covering material. The pouch can be made to receive one or more padding panels. In certain embodiments, replaceable padding panels can be inserted into the protective sports headgear device through an opening made by separating a separable portion between the outer covering material and the inner covering material.
In certain embodiments, the accommodation portion can comprise a hole or aperture. In certain embodiments, the protective sports headgear device comprises three padding panels. In certain embodiments with three padding panels, the first padding panel can substantially cover the right side of a person's head, the second padding panel can substantially cover the left side of a person's head, and the third padding panel can substantially cover the top-center and back-center of a person's head. In certain embodiments with three padding panels, the third padding panel can comprise an expandable portion. The expandable portion can be capable of expanding, straightening out, or stretching when the user puts the protective sports headgear device on their head. In certain embodiments, the expandable portion can comprise an accordion or zig-zag shaped portion of padding material. In certain embodiments, the expandable portion can allow the third padding panel to stretch to accommodate the shape of a person's head and/or their hair. In certain embodiments with three padding panels, the protective sports headgear device can comprise a hole or aperture. In certain embodiments with three padding panels, the protective sports headgear device can comprise removable and/or replaceable padding panels. In certain embodiments with three padding panels, the protective sports headgear device can comprise substantially elastic portions.
In certain embodiments, the protective sports headgear device 210 can comprise any of the features or combinations of features described above for embodiments of the protective sports headgear device 10 that do not have the specific configuration of three or four padding panels as described in connection with the protective sports headgear device 210. For example, the protective sports headgear device 210 can comprise features or combinations of features including, but not limited to, a facemask, goggles, padding material comprising Poron-XRD, padding material with a plurality of raised surfaces or ridges, padding material layer that includes a bladder, waterproof or protective coatings, buoyant padding material, multiple padding material layers, a hard plastic padding material layer, or joints that connect padding panels.
In certain embodiments, the protective sports headgear device 210 can comprise designs, pictures, logos, words, numbers, or other ornamentations, decorations or designations. In certain embodiments, these ornamentations, decorations or designations can be applied to or integrated into the outer covering material. For example, this could be accomplished through methods including, but not limited to, dye sublimation, silk-screening, or other similar processes. In certain embodiments, these ornamentations, decorations or designations can be integrated into the protective sports headgear device 210 in another way. For example, the protective sports headgear device 210 could comprise a design underneath the outer covering material such that it were visible through the outer covering material. This could allow for materials to be used that could otherwise be degraded by sunlight and/or chlorine if it were on the outside of the protective sports headgear device 210.
The foregoing description details certain embodiments of the invention. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the invention can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the invention with which that terminology is associated. The scope of the invention should therefore be construed in accordance with the appended claims and any equivalents thereof.
