Abstract
An article of clothing includes a waterproof inner fabric layer and an outer fabric layer. An outer opening is defined in the outer fabric layer and is selectively opened and closed by a standard zipper. A portion of the inner fabric layer extends between the edges of the outer opening and defines an inner opening. The inner opening is selectively opened and closed by a water-resistant zipper. Venting material extends between the edges of the inner opening and allows air to flow through the inner opening when both the inner and outer openings are opened.
Description




FIELD OF THE INVENTION




The present invention relates to a garment ventilation system particularly for use on motorcycles or similar vehicles where it is desirable for the garment to be changeable from a waterproof configuration to a ventilated configuration, and where protection from abrasive injury is of concern.




BACKGROUND OF THE INVENTION




It is known in the art to provide a waterproof garment for protection from rain or vehicle spray when riding in inclimate weather on motorcycles or other open-air vehicles. These garments are typically made of impermeable materials such as various plastics or GORTEX™ brand breathable, waterproof fabric. It is also well known in the art to provide a durable, abrasion resistant garment for protection from abrasive injuries that may result due to a fall from a motorcycle or similar vehicle. These garments have typically been made of leather or other heavy materials that resist tearing.




In order to provide a versatile garment that is both waterproof and protective, manufacturers typically use a combination of materials such that one portion of the garment provides abrasion resistance and another portion of the garment is waterproof. It is also well known in the art to provide vents on the garment promoting airflow through the garment when water impermeability is not a concern in order to cool the wearer of the garment. Many prior art garments provide the above listed properties but often the combined demands of an effective ventilation system and water impermeability create modestly effective, difficult to use, and poorly fitting garments.




The goal of the present invention is to provide a garment that is abrasion resistant, waterproof, and well ventilated. A further goal of the present invention is for the ventilation system of the garment to be easily adjusted while operating a vehicle such as a motorcycle and for the fit of the garment to be modifiable based on the degree of ventilation desired.




SUMMARY




The present invention provides an article of clothing having an outer fabric layer with an outer opening and an inner fabric layer with an inner opening coupled to the outer fabric layer. The inner fabric layer is substantially waterproof and a water-resistant closure is coupled to the inner fabric layer along the inner opening.




In one embodiment, the outer fabric layer of the article of clothing is made of an abrasion-resistant nylon, and the inner fabric layer is made of a waterproof polymer-coated nylon. The inner opening is preferably aligned with the outer opening and the water-resistant closure may be movable between an open position, which allows air to pass through the inner opening, and a closed position, which substantially prevents water from passing through the inner opening. The water-resistant closure is preferably a water-resistant zipper. Venting material having several small holes may be secured to the inner fabric layer and may cover a portion of the inner opening to allow air to flow through the interior of the jacket.




The article of clothing may be made by forming an outer opening in an outer fabric layer and forming an inner opening in an inner fabric layer. The inner fabric layer may be attached to the outer fabric layer such that it extends across the outer opening. A water-resistant closure may be provided to selectively open and close the inner opening. The inner opening may be aligned with the outer opening and venting material may be attached such that it extends across the inner opening.




Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims, and drawings.

DETAILED DESCRIPTION





FIGS. 1 and 2

illustrate a motorcycle jacket


8


including the ventilation system of the current invention embodied in a jacket sleeve


10


. The sleeve


10


includes an outer layer in the form of an abrasion-resistant fabric


14


defining an outer opening


18


. An inner layer in the form of a waterproof fabric


22


extends across the outer opening


18


and defines an inner opening


26


. A layer of venting material


28


extends across the inner opening


26


and includes a plurality of holes (not shown). An outer closure in the form of a standard zipper


30


is adapted to close the edges


34


of the outer opening


18


, and an inner closure in the form of a water-resistant zipper


38


is adapted to close the edges


42


of the inner opening


26


.




The sleeve


10


is preferably constructed such that the abrasion-resistant fabric


14


protects the wearer in case of a fall but is not necessarily water impermeable. The abrasion-resistant fabric


14


may include natural materials such as leather, recently developed synthetics, or other suitable materials offering similar wear protection. The waterproof fabric


22


is preferably adapted to be comfortable and non-abrasive as it may often come into direct contact with the wearer's skin. The waterproof fabric


22


and abrasion-resistant fabric


14


are generally stitched together such that they form one continuous jacket


8


in the traditional configuration. However, the current invention is readily adaptable to the style of jackets having a removable inner liner that either zips to, or is otherwise removably attached to the outer layer based on the degree of weather protection desired. In the current embodiment the inner and outer openings


26


,


18


of the ventilation system are located on the medial portions of each jacket sleeve


10


and are oriented in a substantially longitudinal direction with respect to the sleeves


10


. It should be apparent to one of ordinary skill in the art that the ventilation system disclosed herein may be located or orientated in a number of ways on the jacket


8


or any other article of clothing where selective water-impermeability and air-permeability is desired without escaping the scope and spirit of the current invention.




The standard zipper


30


includes joinable rows of zipper teeth


44


and a zipper closure


46


that may be used to engage and disengage the rows of zipper teeth


44


, selectively converting the outer opening


18


between the opened and closed configuration. In a highly preferred embodiment the edges


34


of the outer opening


18


extend from a position generally associated with the center of a wearers upper arm to the terminal end or cuff


50


of the jacket sleeve


10


. The outer opening


18


most preferably includes two zipper closures


46


such that the outer opening


18


may be opened from either end and selectively adjusted to a plurality of partially opened configurations.




The waterproof fabric


22


is coupled to and extends across the outer opening


18


of the abrasion-resistant fabric


14


allowing the edges


34


of the outer opening


18


to separate when the zipper teeth


44


are not engaged. The inner fabric layer


22


also substantially completely lines the interior of the sleeve


10


and jacket


8


such that the entire jacket


8


is substantially waterproof. When the outer opening


18


is closed, the inner fabric layer


22


is gathered and folded such that it lies between the outer fabric layer


14


and the wearer's arm.




In the illustrated embodiment, the inner opening edges


42


are substantially aligned with the outer opening edges


34


and extend generally from an area associated with the middle of a wearer's upper arm to the middle of a wearer's forearm. The water-resistant zipper


38


includes joinable rows of specially designed water-resistant zipper teeth


52


and a water-resistant zipper closure


54


that may be used to selectively engage the rows of water-resistant zipper teeth


52


. Adjusting the water-resistant zipper


38


converts the inner opening


26


from the opened, ventilated configuration to the closed, waterproof configuration and vice-versa. Although the current embodiment of the invention includes one water-resistant zipper


38


, additional closures may be added or substituted as desired (e.g., by another water-resistant closure such as a zip-lock closure).




The section of venting material


28


extending across the inner opening


26


includes a plurality of holes allowing substantially unrestricted flow of air therethrough while preventing large debris from entering the interior of the sleeve


10


. The venting material


28


is generally stitched to each inner opening edge


42


and is preferably configured such that an excess of venting material


28


allows the inner opening edges


42


to be spread apart when opened, facilitating additional airflow through the inner opening


26


. When the inner opening


26


is closed the venting material


28


folds substantially in half forming a pleat that lies beneath the surface of the waterproof fabric


22


.





FIG. 3

illustrates another embodiment of the current invention in the form of a leg


58


of otherwise traditional motorcycle riding pants. In this embodiment, an outer opening


62


is defined in an abrasion-resistant fabric


60


and extends from an area substantially associated with a wearer's hip and continues to a pant cuff


66


nearest the wearer's foot. An inner opening


70


is substantially aligned with the outer opening


62


and extends from an area substantially associated with the middle of a wearer's thigh to the middle of a wearer's shank. In this embodiment, the construction of the inner opening


70


and outer opening


62


is substantially the same as the previously described embodiment in the form of a sleeve


10


. The outer opening


62


is selectively closed with a standard zipper


74


including engageable rows of zipper teeth


78


. A waterproof fabric


82


extends between the outer opening edges


86


allowing the edges


86


to separate when the outer opening


62


is opened. Two zipper closures


90


associated with the outer opening


62


are adapted for varying the configuration of the outer opening


62


from fully closed, to fully open, or to a plurality of partially open positions. The inner opening


70


is selectively closed with a water-resistant zipper


94


including engageable rows of water-resistant zipper teeth


98


, a water-resistant zipper closure


100


is used to engage or disengage the rows of water-resistant zipper teeth


98


, however additional closures may be added or substituted as desired (e.g., by another water-resistant closure such as a zip-lock closure). Venting material


102


having a plurality of small holes (not shown) extends between the inner edges


106


of the inner opening


70


and allows air to flow therethrough.




Both the standard zippers


30


,


74


of the outer openings


18


,


62


and the water-resistant zippers


38


,


94


of the inner openings


26


,


70


are easily and efficiently opened and closed with one hand. This is especially important when the garments are used on motorcycles because it allows the wearer to safely and conveniently adjust the openings while riding.




It is well known in the art that a certain amount of “billowing” typically occurs in motorcycle apparel under normal operating conditions. Billowing results when turbulent air passes through the garment either intentionally through vents, or unintentionally through inadequate garment closures (e.g. loose cuffs, waistbands, necklines, etc.) causing the material of the garment to flap. Billowing is often annoying and distracting to a rider, as such, it is generally preferred to minimize billowing in motorcycle garments. However, billowing also greatly increases airflow through a garment and is thus an effective method for cooling the rider in hot weather. The ventilation system of the current invention as embodied in either a motorcycle jacket sleeve


10


or pant leg


58


offers a unique solution for adjusting the amount of billowing based on the amount of airflow and subsequent cooling that is desired. While the specific configuration of zipper closures may vary between the sleeve


10


and the pant leg


58


, both embodiments have similar a similar degree of adjustability; therefore only the sleeve


10


is discussed below.




The zipper closures


46


of the outer opening


18


are configured such that when the outer opening


18


is in the fully closed configuration one of the zipper closures


46


is at an upper end of the opening


18


, near the wearer's shoulder, and the other zipper closure


46


is at a lower end of the opening


18


, near the wearer's wrist. In this first configuration the jacket sleeve


10


has a minimum diameter throughout its length, in particular, the cuff


50


is substantially snug around the wearer's wrist, preventing airflow into the sleeve


10


. The combination of a snug fit at the cuff


50


and a minimum diameter throughout the sleeve


10


results in a minimum amount of billowing of the jacket


8


. The first configuration is ideal for high-speed travel in cold to mild temperatures or any travel involving rain. The snug fit of the cuff


50


also prevents the sleeve


10


of the jacket


8


from moving up the wearer's arm.




If more billowing is desired the wearer may adjust the zipper closures


46


such that both closures


46


are located near the cuff


50


of the sleeve


10


. This will disengage the zipper teeth


44


along the entire length of the outer opening


18


except for a small portion near the wearer's wrist. In this second configuration the central portion of the sleeve


10


has a maximum diameter and may flap freely in the wind, aiding in the circulation of air within the jacket. The cuff


50


remains snug around the wearer's wrist or ankle preventing the entry of air or water therethrough. The second configuration is ideal for slightly elevated temperatures where a small degree of circulation within the garment is desired and water impermeability may still be of concern.




To increase air ventilation further, the inner opening


26


may be opened allowing outside air to freely enter the garment. This third configuration is ideal for high speed riding in hot temperatures where a snug fit of the cuff


50


is important to keep the sleeve


10


from shifting but a higher amount of ventilation is desired. When a snug fit of the cuff


50


is not required, such as during slower riding, and a maximum amount of ventilation is desired, both zipper closures


46


may be moved to the upper end of the outer opening


18


. In this fourth configuration the sleeve


10


, including the cuff


50


is fully expanded throughout its length, allowing air to flow directly into the sleeve


10


through the loosely fitting cuff


50


. The inner opening


26


may or may not be opened in the fourth configuration to increase or decrease the amount of ventilation accordingly. A further function of the fourth configuration is that it allows for easy donning and removal of the garment because the sleeves


10


and cuffs


50


are fully expanded along their lengths such that a wearer may easily pass his or her hands through the sleeves


10


and cuffs


50


of the jacket


8


.
