OUTERWEAR FOR SPORTS PLAYED ON ICE
Disclosed is outerwear for sports played on ice. The outerwear having an outer shell and one or more gripper sections positioned on the outer shell. The one or more gripper sections being made from a material with a coefficient of kinetic friction on ice that is greater than the coefficient of kinetic friction between the outer shell and ice. Raised portions, in the form of three-dimensional geometric shapes, can be positioned on or integrated with the gripper sections to provide additional gripping ability. In the event of a fall on the ice, the gripper sections will come into contact with the ice surface to slow the wearer down compared to if the user fell without the gripper sections.
The present invention generally relates to outerwear for sports played on ice. More specifically, the present invention relates to outerwear having one or more sections of material that can slow the forward momentum of the wearer on the ice when the section comes into contact with the ice.
BACKGROUND OF THE INVENTIONRecent advances in equipment technology and conditioning of athletes have dramatically increased the speed in which some ice sports are played. In addition, new sports, such as short track speed skating and ice cross downhill, have athletes in close contact with one another at very fast speeds. Although these factors cannot be solely blamed for the increased number of serious injuries in such sports, they have definitely played a role.
Hockey is one sport where the number of head injuries due to players hitting the boards at a high rate of speed has increased over the years, and has become a concern for most parents of youngsters playing the sport. In an effort to stop an icing call in the sport, players routinely find themselves racing at full speed towards the end boards. If the player catches an edge or loses his or her balance, they can find themselves on the ice sliding towards the boards with no way to stop. Moreover, since modern day hockey equipment and uniforms are designed to be lightweight, the outer shell of the equipment is often made from nylon or a similar material, which has a low coefficient of kinetic friction when on ice. As such, the speed in which the athlete was moving when the fall occurred is essentially the same velocity in which they hit the boards.
In an effort to combat such injuries, the padding worn by players has been improved to absorb more energy in the event of a collision. However, the padding does not cover all areas of the player's body, thus leaving some areas exposed. Moreover, the padding and equipment worn by the player does very little to protect a player when the athlete hits the boards with one or more parts of their body being in an awkward position and vulnerable to injury. In this case, the player's body will still hit the board with full force, thus often leading to serious injury.
U.S. Pat. No. 3,835,470 provides an article of clothing that is designed to slow a skier down in the event of a fall by providing spikes on the skiers outfit, which dig into the snow to slow and eventually stop the skier. Such outfits would not be suitable for sports, such as hockey and short track speed skating, since any elements that dig into or damage the ice surface in an effort to slow the athlete down creates a safety concern for other athletes in the game.
Accordingly, there is a need to develop ways to slow down the forward momentum of an athlete in the event of a fall on ice without damaging the ice surface in the process.

These and other features, aspects and advantages of the present invention will become better understood with regard to the following description and accompanying drawings wherein:
The following description is of an embodiment by way of example only and without limitation to the combination of features necessary for carrying the invention into effect.
The present invention is directed to outerwear for sports played on ice. The outerwear having an outer shell and one or more gripper sections positioned on the outer shell. The gripper sections being made from a material with a coefficient of kinetic friction on ice that is greater than the coefficient of kinetic friction between the outer shell and ice.
The present invention will be described with reference to hockey uniforms. However, it should be understood that similar gripper sections could be applied to outerwear worn in other sports played on ice, such as, but not limited to, speed skating, ringette, broomball, bandy and ice cross downhill. In each of these sports, the ability to slow a person down that has fallen on the ice improves the safety of the sport. The specific locations and shapes of the gripper sections on the outerwear and preferred design of the raised portions on the gripper sections may be specific to sport being played. For example, in short track speed skating it may be advantageous to position the gripper sections along the lateral sides of the outerwear, since most falls happen when the skater is rounding the corners and their body is at an acute angle to the ice.
As shown in
The performance of the outer shell (2) can be enhanced by including materials that have properties, which enhance the durability of outerwear. For example, the nylon threads used to make the outer shell (2) can be coated with a material that makes the outer shell resistant to rips and cuts. In addition, the fibers used to construct the outer shell (2) can be woven in such a pattern that the outerwear (1) has improved properties, such as being wind resistant or breathable.
As shown in
The gripper sections (3) can be integrated into the outerwear (1), so that the gripper sections (3) are part of the finished product. Alternatively, individual premade gripper sections (3) can be manufactured to be added to outerwear originally sold without such sections (3). In this case, the gripper sections (3) are provided with an adhesive backing that allows the sections (3) to be attached to the outerwear (1). In another embodiment, the gripper sections (3) may be sewn onto the outerwear (1).
A variety of natural and synthetic materials may be used as the gripper sections (3). For example, natural or synthetic rubbers, polymers and other textiles, besides nylon, can be manufactured to provide a coefficient of kinetic friction that is higher than the material of the outerwear. Of these, rubber compounds, either natural or synthetic, are preferred due to their high coefficient of kinetic friction with ice, their compressive properties, low cost and resiliency in cold temperatures. A rubber compound comprising natural rubber and silica will provide a coefficient of kinetic friction on ice that is sufficient to slow down the forward momentum of the wearer in the event of a fall compared to if the wearer were to fall on the ice with the same velocity wearing only the outerwear (1). Other examples of rubbers suitable for use in designing the gripper sections (3) include, but are not limited to: natural rubber; isoprene rubber; butadiene rubber; butyl rubber; chlorobutyl; styrene butadiene rubber; silicone (and fluorosilicone rubber); ethylene acrylic; hydrogenated nitrile rubber; polychloroprene; nitrile rubber; polyurethane rubber; chlorinated polyethylene; epichlorhydrin; ethylene propylene rubber; polysulphide rubber; polynorbornene rubber; tetra-fluoroethylene/propylene, and combinations of any two or more of these.
Although the mere addition of one or more gripper sections, as described above, to outerwear will decrease the forward momentum of the wearer in the event of a fall, the effectiveness of the gripper sections can be improved by making the gripper sections with a rough outer surface and/or by including raised portions on the gripper sections. The texture of the outer surface of the gripper section can be roughened by integrating regular or irregular-shaped bits of material on the outer surface of the gripper section. In most cases, the material used for roughening the outer surface of the gripper section will be the same as the gripper section itself. However, the effectiveness of the gripper section may be improved by making the roughened surface from a softer compound.
The effectiveness of the gripper sections (3) in slowing down a wearer of the outerwear (1) of the present invention in the event of a fall on ice can also be improved by including raised portions (4) on the gripper sections (3). These raised portions (4) can be provided on a gripper section (3) with or without a roughened outer surface. As with the roughened outer surface, the raised portions (4) can made from the same material as the gripper section (3) or from a material with different physical properties. However, it is preferred that the raised portions (4) are made from a material will not damage the surface of the ice in the event of a fall. As this would pose an additional safety concern to the other players or athletes on the ice.
The raised portions (4) can be provided in a variety of different shapes and sizes depending upon the application and the sport being played. For example, the raised portions (4) can be provided on the gripper sections (3) in geometric shapes or a combination of a number of different geometric shapes, such as, but not limited to, nubs, cones, cubes, ellipsoids, cylinders, cuboids and rhombohedrons (see
In an effort to improve the ability of the gripper sections (3) to slow a wearer down in the event of a fall, the raised portions (4) are preferably made of a material that is resilient, but flexible, to allow the raised portions (4) to deform when in contact with the ice surface. Natural rubber, natural rubber with silica and synthetic rubbers have or can be designed to have these properties. The deformability of the raised portions (4) will allow for a greater surface area of material having a coefficient of kinetic friction on ice that is greater than the coefficient of kinetic friction between the outer shell (2) and ice to make contact with the ice.
For the purposes of this discussion, locations on the outerwear of the present invention will be described using the international standard for anatomical directions, wherein anterior means towards the front of the body, posterior means the back of the body, superior means toward the head or upper part of a structure, inferior refers to the lower part of a structure or away from the head, proximal means closer to the trunk while distal is away from the trunk, medial refers to a structure toward the midline of the body and lateral away from the midline. Intermediate describes a position between the medial and lateral areas of the structure.
With reference to
Hockey pants (20) can be provided with the gripper sections (3) partially or completely encircling the pants (20) in the vicinity of the openings for the user's legs. Alternatively, as shown in
The outerwear (1) of the present invention can also include hockey socks (30)(
Similarly, gripper sections (3) with, or without, raised portions (4) can also be provided on hockey gloves (40). In particular, gripper sections (3) positioned on the cuff (45) and/or the dorsal region (46) of the glove (40) will provide some gripping ability, in the event of a fall, without interfering with the overall function of the glove. Although providing gripper sections (3) on hockey socks (30) and hockey gloves (40) will be less effective than gripper sections (3) placed on other parts of the hockey uniform at slowing the wearer down in the event of a fall, it will have some positive impact in the overall performance of the outerwear (1).
The present invention has been described with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
