FIELD OF THE INVENTIONThe present invention relates generally to a protective garment having improved access, and more particularly to a water sport garment providing protection from cold water and having an improved access system for entry into or exit from the garment.
BACKGROUNDGarments that provide protection for an individual's body have existed in some form for many years as cold environmental conditions can quickly drain a body of heat. These protective garments generally provide protection in two ways: shielding the body from elements of the cold conditions, such as a shell limiting the ability of a cold breeze to reach a person, and insulating a body from cold temperatures. Because water has a very high thermal conductivity, cold water can be especially dangerous since it can quickly chill a person by stripping away body heat. This is particularly of concern when the exposure to water includes partial or total submersion in the water. In these circumstances, traditional cold weather protective garments are generally ineffective in protecting the person because the water saturates them, which compromises their insulative properties. However, two types of garments have been developed that provide significantly better protection against cold water. The first type of garment acts to seal the water away from the body so that other warm clothing can provide insulation without becoming wet. An example of this type of garment is a dry suit. The second type of garment works by allowing a small layer of water to enter between the garment and the person's body and then trapping the small layer of water so that it can be heated and provide a warm layer next to the person's body. An example of this type of garment is a wetsuit.
Dry suits typically use tight seals on the wrists and neck of the suit to prevent water from entering the space between the suit and the body of the person. These suits can further use incorporated foot booties or have additional tight seals around the ankles to prevent water from entering the space between the suit and the body of the person. The dry suit itself generally includes water impermeable material such as a synthetic rubber and sealed access zippers. However, because zippers do not provide as effective a seal as the water impermeable material, the use of zippers is generally minimized as much as possible (such as a single zipper going across the upper torso from shoulder area to shoulder area), which can make donning a dry suit a difficult chore. Additionally, because the seals around the open parts of the suit must restrict the access of water, they are generally difficult to fit through.
Wetsuits, on the other hand, typically allow some water to enter the space between the suit and the body of the person wearing the suit and then trap that water in the space between the wetsuit and the person's body. To help accomplish this basic goal, most wetsuits include a synthetic rubber material such as neoprene. This synthetic rubber provides some repellency protection from the environmental conditions, but also helps insulate an individual from the cold water by trapping a thin layer of water next to an individual's body. The thin layer of water can be heated by the body and provide a warm layer next to the individual's body. To ensure this insulative feature is effective, wetsuits are typically tight fitting so that there is only a small layer of water next to the body to heat, and have constrictive areas of material around the arm and leg cuffs to help trap this thin layer of water next to the body. However, because the effectiveness of wetsuits depends on this tight fit and constrictive cuffs, they can be very difficult to enter into or exit from, especially because most wetsuits only have a single zipper running from the neck opening of the suit to the mid section area on the front or back of the suit.
As discussed above, both of these types of protective garments, and indeed substantially all water sport protective garments, require a certain amount of mobility and dexterity to enter into or exit from the garments. Access openings are also traditionally kept to a minimum, as they are more susceptible than the garment material for allowing water in. Although the access difficulties of these types of suits do not substantially hinder most adults, they can prevent a child or person with limited mobility from being able to use the protective suit. This in turn may prevent these people from being able to safely participate in many activities in and around water. Thus, a water sport protective garment is desirable where the protective garment provides an improved access system while still maintaining its effectiveness in providing protection from cold water. These and other problems in conventional protective garments are addressed by embodiments of the present invention.
SUMMARYEmbodiments of the present invention provide a water sport protective garment having improved access and being structured to effectively protect a person wearing the garment from cold water when the person is at least partially submerged in the cold water. In one embodiment, the water sport protective garment includes a torso portion, pant-leg portions extending from the torso portion, and non-openable sleeve portions extending from the torso portion. To help facilitate access to the garment, the garment further includes at least one openable seam extending from the torso portion down each of the pant-leg portions such that when the openable seam is opened a section of the torso portion and sections of the leg portions can be displaced.

DETAILED DESCRIPTIONTo address the problems discussed above and other problems, embodiments of the present invention are directed to a water sport garment providing protection from cold water and having an improved access system for entry into or exit from the garment. Some of these embodiments are described below in detail, and in addition, some specific details are shown for purposes of illustrating the inventive principles. However, numerous other arrangements may be devised in accordance with the inventive principles of this patent disclosure. Thus, while the present invention is described in conjunction with the specific embodiments illustrated in the drawings, it is not limited to these embodiments or drawings. Rather, it is intended to cover alternatives, modifications, and equivalents that come within the scope and spirit of the inventive principles set out in the appended claims. Further, well known processes have not been described in detail in order not to obscure the present invention. Thus, the inventive principles are not limited to the specific details disclosed herein.
Throughout this disclosure, the term water sport protective garment is used to describe the garment that is the subject of the present invention. Although this garment may be embodied in many different forms, two of the most common methods of structuring water sport protective garments are as wetsuits and dry suits. It will be noted below in the discussion of the exemplary embodiments of the present invention if a certain embodiment is particularly well suited for either of these types of protective garments.
FIGS. 1 and 2 illustrate front views of a water sport protective garment according to an embodiment of the present invention.FIG. 1 illustrates a first front view of theprotective garment100 in a closed state andFIG. 2 illustrates a second front view of theprotective garment100 in an open state. Although, this exemplary embodiment may be implemented in several types of garments, it may be particularly well suited as a wetsuit because of the lack of sealing around the neck area.
Referring toFIGS. 1 and 2, aprotective garment100 includes atorso portion110,sleeve portions120, and pant-leg portions130. Thesleeve portions110 are integrated with thetorso portion110 and extend from thetorso portion110 to sleeve-ends125. The sleeve-ends125 may just be the end of the sleeve material and simply hemmed. However, the sleeve-ends125 may also include separate material attached to the sleeve material. The sleeve-ends125 may also be formed to have a cuff of thicker material. AlthoughFIGS. 1 and 2 show thesleeve portions110 as relatively long sleeves, thesleeve portions110 may extend only a short distance from thetorso portion110, such as only extending a small distance down the upper arm of a person wearing theprotective garment100, or they may extend for a relatively long distance, such as down to the wrist of a person wearing theprotective garment100. Sleeve seals128 may be arranged at the sleeve-ends125 so as to be integrated with the sleeve-ends125. Additional details about the sleeve seals128 are discussed below with respect toFIG. 3c.
The pant-leg portions130 are also integrated with thetorso portion110 and extend from thetorso portion110 to pant-ends135. Similar to the sleeve-ends125, the pant-ends135 may just be the end of the pant-leg material or include separate material attached to and integrated with the pant-leg material. Further, the pant-end135 may have a hemmed finish or be formed in a cuff arrangement. Additionally, the pant-leg portions130 may extend only a short distance from the torso portion, such as extending a small distance down the upper leg of a person wearing theprotective garment100, or they may extend for a relatively long distance, such as down to the ankle of a person wearing theprotective garment100.
Thetorso portion110 has a front section, a back section, and side sections. Additionally, thetorso portion110 has an upper section that includes aneck opening115 and a lower section. Thesleeve portions120 extend from the upper section of thetorso portion110 and the pant-leg portions130 extend from the lower section of thetorso portion110. Thetorso portion110, thesleeve portions120, and the pant-leg portions130 may include a material that is water impermeable. This material may be a synthetic rubber, such as neoprene.
The system by which theprotective garment100 illustrated inFIGS. 1 and 2 may be accessed includes a plurality of openable seams that extend from the neck opening115 of thetorso portion110 to the pant-ends135 of the pant-leg portions130. In this embodiment, the openable seams may include afirst zipper track150 operable with afirst zipper155 and asecond zipper track151 operable with asecond zipper156. The use of the term “zipper” may refer to a zipper track, a zipper slider, or both mechanisms. Although the openable seam is embodied as a zipper in these embodiments, any type of resealable continuous closure mechanism may be used. In the present embodiment, thefirst zipper track150 extends from theneck opening115 down a first one of the pant-leg portions130 to a first one of the pant-ends135 and thesecond zipper track151 extends from theneck opening115 down a second one of the pant-leg portions130 to a second one of the pant-ends135. Thezippers155 and156 are respectively operable along the first and second zipper tracks150 and151 to provide access to theprotective garment100.
FIG. 1 illustrates theprotective garment100 in a closed state. That is, thezippers155 and156 are operated to fully engage the zipper tracks150 and151. Thezippers155 and156 may be configured to be fully engaged when they are near theneck opening115 as illustrated inFIG. 1 or they may be configured to be fully engaged near the pant-ends135 as illustrated by the phantom lines inFIG. 1. Further,zippers155 and156 may comprise a dual zipper configuration where eachzipper track150 and151 has two sliders operating on it. This dual zipper configuration may allow for additional flexibility in providing access to theprotective garment100.
FIG. 2 illustrates theprotective garment100 in an open state. That is, thezippers155 and156 are operated to fully disengage the zipper tracks150 and151. As shown inFIG. 2, when theprotective garment100 is in an open state, a section of thetorso portion110 and sections of the pant-leg portions130 may be displaced to ease entry into and exit from theprotective garment100. In particular, because sections of the torso and pant-leg portions110,130 can be displaced, a child or person with limited mobility may easily step into the protective garment, put their arms through thesleeve portions120, and zip up thezippers155 and156.
These steps may also be carried out with the help of an assistant such as a parent or friend. If thezippers155 and156 fully disengage the pant-leg portions130 such that the pant-ends135 open, a child or person with limited mobility may be laid in theprotective garment100, insert their arms in thesleeve portions120, and have an assistant engage thezippers155 and156 to zip up theprotective garment100.
As shown inFIGS. 1 and 2, thesleeve portions120 of theprotective garment110 do not open. That is, thesleeve portions120 do not have a separate zipper access system. This is in part because as mentioned above, zippers or other openable seams tend to let in more water than the insulative material itself. Second, zippers can be more costly to implement than just providing fully formed sleeves. Also, children and people with limited mobility generally have an easier time guiding their arms and hands through sleeves than in donning a complete tight fitting garment because they are generally used to inserting their arms through sleeves. Additionally, the sleeves may be formed to fit more loosely on the person and then have cinching mechanisms (discussed with respect toFIGS. 5a-5d) that can help tighten the fit after the person has inserted their arms into thesleeve portions120.
FIGS. 3a-3cillustrate detailed views of embodiments of the pant-ends and sleeve ends.FIG. 3aillustrates a detail view of a pant-end according to an embodiment of the present invention.
Referring toFIG. 3a, each pant-end235 may be structured so that thezipper track250 extends to the end of the fabric. In this configuration, thezipper255 may fully disengage thezipper track250 such that the pant-end235 completely opens up. The configuration of this embodiment may have the advantage of allowing access to persons that may have difficulty guiding their legs through a tight cuff or seal, such as a young child or a person with limited mobility in their legs.
FIG. 3billustrates a detail view of a pant-end according to another embodiment of the present invention. Referring to the embodiment illustrated inFIG. 3b, each pant-end335 may be structured so that thezipper track350 does not extend to the end of the fabric. Thus, in this embodiment, the pant-end335 remains partially closed even when thezipper track350 is completely disengaged. Each pant-end335 may also have a pant-leg seal338 integrally formed with the pant-end335. The pant-leg seal338 may include a rubber or synthetic rubber gasket that limits or completely prevents water from entering the protective garment. In a wetsuit configuration, thisseal338 may also help prevent the thin layer of warmed water from leaving or interchanging with new cold water. The configuration of this embodiment may have the advantage of providing improved sealing functionality and improved warmth. Also, this embodiment may be easier to operate with children that squirm or move while the suit is being donned. That is, it can be very difficult to engage a zipper that is on two separate sections of material, especially when one or both of the sections of material is being displaced by a moving body.
FIG. 3cillustrates a detail view of a sleeve-end and sleeve seal according to an embodiment of the present invention. Referring toFIG. 3c, eachsleeve portion120 may have asleeve seal128 integrally formed with the sleeve-end125. Similar to the pant-leg seal338 shown inFIG. 3b, thesleeve seal128 may be formed of a separate piece of material and attached to the sleeve-end125. Thesleeve seal128 may include a rubber or synthetic rubber gasket that limits water from entering the protective garment. A sleeve-seal128 that completely prevents water from entering the protective garment is necessary for dry suits. On the other hand, in a wet suit configuration, the sleeve-seal128 may help prevent the thin layer of warmed water form leaving or interchanging with new cold water. While this seal may make donning thesleeve portions120 of the protective garment more difficult, it will also make the garment more effective in providing insulating protection. Thus, the use of seals in specific embodiments may be dependent on the physical capabilities of the person the garment is designed for.
FIG. 4 illustrates a front view of a protective garment according to another embodiment of the present invention. The embodiment illustrated inFIG. 4 is similar in many ways to the embodiment illustrated inFIG. 1. Thus, elements that are similarly structured and/or have similar functionality will not be described again. This embodiment may again be better implemented as a wetsuit because of the lack of a seal in the neck and upper torso areas.
Referring toFIG. 4,protective garment400 includes atorso portion410,sleeve portions420 extending to sleeve ends425, and pant-leg portions430 extending to pant-ends435. Theprotective garment400 also includes an access system that features zipper tracks450 and451 operable byzippers455 and456. The operation of this access system is similar to the one discussed above with respect to the embodiment illustrated inFIGS. 1 and 2. In this embodiment, however, the sleeve-portions420 include hand flap folds480 formed adjacent to the sleeve-ends425. The hand flap folds480 may be structured to be able to fold over the corresponding sleeve-ends425 andsleeve seals428 if present. The hand flap folds480 may help improve the overall warmth of theprotective garment400 by protecting the hands of the person wearing theprotective garment400 from direct contact with cold water. Each hand flap fold may be formed by stitching along the sides and end adjacent to the sleeve-end425 while leaving the end facing thetorso portion410 loose. This arrangement allows the flap to be folded over the sleeve-end425 to cover the sleeve-end425. The right sleeve illustrated inFIG. 4 shows thehand flap fold480 in an unused state, while the left sleeve of theprotective garment400 shows thehand flap fold480 folded over the sleeve-end425.
Theprotective garment400 may also include anintegrated hood470. Thehood470 my be integrally formed with a least a section of thetorso portion410 near theneck opening415. As a substantial amount of body heat can be lost through the head, ahood470 may be desirable in situations where the water temperature is especially cold, or there is a likelihood of prolonged exposure to the cold water. Thehood470 may be donned after the person is in theprotective garment400 with thezippers455 and456 fully engaged in a closed state. Additionally, thehood470 may be donned during entry into theprotective garment400.
The pant-leg portions430 of the protective garment may also includebooties490 integrally formed with the pant-ends435. Thebooties490 can be made of a moderately flexible material to fit a variety of foot sizes and may include traction patterns (not shown) on the bottom parts for improved grip while standing or walking. In this embodiment, the zipper tracks450 and451 do not extend all the way to the integrated booties. To don theprotective garment400 withbooties490, a person would have to slip his or her feet into each of the booties, insert their arms into the sleeve portions, and use thezippers455 and456 to fully engage the respective zipper tracks450 and451. Having integratedbooties490 may be advantageous in providing additional warmth, as a pant-leg cuff or seal is not required, and may be helpful in providing general foot protection without the need for separate footwear.
FIGS. 5a-5dillustrate side views of a protective garment showing different configurations of the openable seam according to embodiments of the present invention. Each ofFIGS. 5a-5dillustrate an embodiment similar to the embodiment shown inFIG. 1. However, the embodiments shown inFIGS. 5a-5dillustrate various openable seam or zipper configurations. In addition to illustrating various openable seam or zipper configurations, the embodiments shown inFIGS. 5a-5dinclude acinching mechanism560. The cinching mechanism may allow for a tighter and more customized fit of the wet suit. Although only onecinching mechanism560 is shown in each of these embodiments, a plurality of cinchingmechanisms560 may be present to further customize the fit of each protective garment500.Cinching mechanisms560 may be especially useful where the protective garments are made for children because children tend to quickly outgrow garments that have a set limited size. The cinchingmechanisms560 may include fasteners such as Velcro straps, string ties, buttons, loops, cinchable bungee cords, and the like.
Referring toFIG. 5a, the openable seams orzippers550aare formed on a back section orback panel512 of thetorso portion510 and back sections of the pant-legs530. Here, it may be difficult for a single person with limited mobility to don the suit by himself or herself, but it may be easier if the person has an assistant and can lie face down in the suit to don theprotective garment500a.
Referring toFIG. 5b, the openable seams orzippers550bare formed on a front section orfront panel511 of thetorso portion510 and a front section of the pant-legs530. Here, it may be easier for a single person with limited mobility to don the suit by himself or herself, but the openable seams orzippers550bmay interfere with a use of the suit, such as in surfing where a person typically paddles out to waves with the front part of their torsos on their surfing boards.
Referring toFIG. 5c, the openable seams orzippers550care formed from theneck opening515 partially down the back512 of thetorso portion510 and then continuing down thesides513 of thetorso portion510 and sides of the pant-leg portions530. This configuration may allow for even greater access as compared to the embodiments ofFIGS. 5aand5bbecause a greater section of the torso and pant-leg portions will be displaced, which in turn may make it easier to don theprotective garment500c.
Referring toFIG. 5d, the openable seams orzippers550dare formed from theneck opening515 partially down thefront511 of thetorso portion510 and then continuing down thesides513 of thetorso portion510 and sides of the pant-leg portions530. Again, this configuration may allow for even greater access as compared to the embodiments ofFIGS. 5aand5bbecause a greater section of the torso and pant-leg portions will be displaced, which in turn may make it easier to don theprotective garment500d.
FIG. 6 illustrates a front view of a protective garment according to yet another embodiment of the present invention. The embodiment shown inFIG. 6 is similar to the embodiment shown inFIG. 1. Thus, elements that are similar in both embodiments will not be further described. This embodiment may be implemented as a wetsuit or a dry suit because the neck area could be sealed.
Referring toFIG. 6, theprotective garment600 includes a singleopenable seam650 havingzippers655 and656 that extend from thetorso portion610 of theprotective garment600 down each of the pant-leg portions630 to pant-ends635. Although this embodiment is shown having twozipper sliders655 and656, a single zipper slider configuration is also possible. The openable seam may additionally be a water tight sealed zipper, which is typically used with dry suits to prevent all water from entering the space between theprotective garment600 and the person wearing theprotective garment600. However, because these zippers are often fairly delicate, wetsuits usually use a more robust but less water-proof zipper as a little water entry into the space between the person and theprotective garment600 is allowable.
In addition to having the simplicity of only a singleopenable seam650, this embodiment is advantageous because aneck seal617 may be integrally formed with theneck opening615 such that substantially no water can enter theprotective garment600. This is especially necessary where theprotective garment600 is a dry suit, as all water should be prevented from entering the space between theprotective garment600 and the person. Because of the need for dryness within a dry suit, these types ofprotective garments600 require strong gasket seals on all portions of theprotective garment600 that provide a barrier along the skin of the person wearing theprotective garment600. Theprotective garment600 may also have integrated booties as shown in the embodiment ofFIG. 4.
Having described and illustrated the principles of the invention in embodiments thereof, it should be apparent that the invention can be modified in arrangement and detail without departing from such principles. I claim all modifications and variations coming within the spirit and scope of the following claims.
