U.S. Patent Application Publication No. 2004/0148679 issued to Garneau teaches a thermally insulated hand glove for use in sporting activities. The hand glove has a main body for enclosing a user's hand, with a palm area having an exposed wall surface being substantially waterproof. A window aperture is made in a fraction of the palm area. A moisture permeable stretchable membrane is applied to fully close the window aperture, so as to provide an air vent system integral to the palm area for promoting moisture outflow generated from the user's hand palm perspiration outwardly from said glove main body, while controlling accidental moisture inflow seepage from outside weather conditions. The stretchable nature of the arcuate membrane pad biases the thumb finger part of the glove to a tilted location overhanging spacedly over the window, thus reducing the likelihood of accidental access of water or snow to the non waterproof membrane pad covering the window. Garneau discloses a palm vent, while the vents of the subject invention are on the fingers, the glove sidewalls and optionally on the back of the hand. Also, the subject invention relates to vents which are covered by a screen which make the shell of the glove non-waterproof along with the use of a waterproof breathable membrane covering the entire hand allowing all areas of the hand to expel water vapor while remaining dry. This results in superior hand warmth while maintaining dryness. In contrast, Garneau uses a waterproof breathable membrane covering just the vent opening, reducing the transmission of water vapor while maintaining the waterproof characteristics of the shell of the glove. The placement of this vent in the palm also makes the glove wear out rapidly as all waterproof breathable membranes are thin and non-abrasion resistant.
U.S. Patent Application Publication No. 2004/0031087 issued to Griesbach, III teaches an elastomeric glove that contains zones of differing water vapor transmission rates. The glove contains at least one liquid and vapor impermeable zone, i.e., “moisture-impermeable ” zone. Such moisture-impermeable zones generally have a Water Vapor Transmission Rate (WVTR) of less than about 1500 g/m.sup.2/24 hours. Further, the glove also contains at least one liquid-impermeable, but vapor-permeable zone, i.e., “breathable” zone. Such breathable zones generally have a WVTR of at least about 250 g/m.sup.2/24 hours. As a result, the glove may sufficiently inhibit liquids and moisture from contacting the hand during use, and allow water vapor that would otherwise accumulate on the skin of a user to escape from the glove, thereby enhancing the comfort of the user's hands during long periods of use. Griesbach, III teaches an elastomeric glove with at least one liquid and vapor impermeable zone. In contrast, the present invention embodies the concept of a water resistant shell with breathable zones wherein multiple open vents covered by a screen render the outer shell non-waterproof but with a breathable waterproof permeable membrane covering the entire hand, allowing moisture to dissipate while keeping hands dry.

U.S. Pat. No. 6,415,447 issued to Frazier teaches an article of clothing, such as a hand covering, and method of making the same which results in a leakproof and breathable article of clothing with good dexterity. The hand covering includes a body cavity for covering a palm and a dorsum of a hand and at least one seamed finger cavity, extending from the body cavity, for covering at least one finger. The finger cavity has a base adjacent the body cavity and a tip opposite the base. A seam extends between and includes the area of the base and the tip. A cut may be made in the hand covering so that a component of a tape sealing machine may be inserted therein to support the seam to be sealed. Once this seam is sealed, the cut is seamed and sealed. The hand covering may therefore be sealed using a single tape sealing machine to effectively seal all seams while minimizing manufacturing costs. Frazier thus teaches a construction method for tape sealing the seams of a glove to make it waterproof and breathable, unlike the focus of the present invention.

Thus, Edwards et al. teaches a ski glove where a portion of the outer shell is fabricated from a material which is permeable to water vapor and impermeable to liquid water. The outer shell of the subject invention is not impermeable to liquid water.SUMMARY OF THE INVENTION
The subject invention includes a glove that provides superior release of water vapor while keeping the hand dry and warm. When an individual is active in cold weather the body increases blood flow to the body extremities to dissipate excess body heat. This makes the hand expel moisture along with the heat. This moisture is trapped in the glove if it is not allowed to pass out into the atmosphere. Once the activity level is reduced the body reduces blood flow back to the body's core to maintain body temperature. The reduced blood flow to the hands lowers the hand temperature.
If the hands remain dry they are able to maintain a comfortable temperature even with less blood supply. If the hands are wet the heat generated from the hand is easily transmitted to the atmosphere. An illustration of this same phenomenon would be the difference in how fast the body becomes chilled in 60 degree water compared to 60 degree air temperature.
The glove of the subject invention keeps hands dry by having a vent on at least one or more fingers. This allows all water vapor to be released from the outer shell of the glove. Several other gloves are produced with a single air vent on the back of the body of the glove. This vent is not adequate to release all of the water vapor produced by the hand during exercise. The vapor builds up in the fingers and condenses into moisture.
The vents of the subject invention are integrated in finger portions including the exterior edges of the glove and optionally on the back of each hand. The vents enhance moisture release on the palm side without interfering with the palm side functionality. The venting system works in conjunction with a waterproof breathable insert around the entire hand. This membrane allows water vapor to pass through while keeping moisture out. The combination of expelling all internally produced water vapor and stopping water from entering the insulation around the hand from outside the glove is a major benefit of the subject invention.
In prior art gloves, water vapor is trapped between the membrane and the outer shell and condenses into moisture. This trapped moisture chills the hands. The combination of a waterproof breathable membrane and placement of multiple strategic air vents of the subject invention is superior to other gloves with waterproof breathable membranes with or without a single air vent.
The present invention discloses a glove having a back side, two exterior edges, and a palm side and having finger, palm and wrist portions and comprising a non-waterproof exterior layer having an interior and being sized to fit a hand; a waterproof, air-permeable interior layer covering the entire interior of the exterior layer; and a plurality of vapor vents passing through the exterior layer and being located on the glove back side on at least some finger portions, optionally located on the glove back side adjacent the wrist portion and located on two finger portions defining the two exterior edges of the glove wherein the location of the vapor vents keeps the palm portion of the palm side free of air vents to facilitate user palm bending.
The detailed description of the present invention is best understood with the accompanying drawings in which:
The subject invention pertains to articles of environmental protective covering worn on the hands and is contemplated to include by non-limiting example, gloves.
The subject invention has a non-waterproof exterior layer; a waterproof air (and water vapor) permeable interior layer covering the entire interior layer of the exterior layer; and a plurality of vapor vents in the exterior layer and in water vapor communication with the interior layer. The air vents are located on portions of the glove, such as at least the finger portions thereof, including the exterior edges of the glove to keep the palm of the glove free of the air vents to facilitate user palm bending while still providing water vapor venting.

In a second embodiment, interior layer 6 can be comprised of any material or materials capable of achieving the desired air and water vapor permeability and liquid (i.e. water) impermeability. In the second embodiment, interior layer 6 may be formed from films, nonwoven webs, nonwovens coated with a film-forming material (e.g., an emulsion coated onto a meltblown web or a laminate comprising spunbond and meltblown webs), combinations thereof, and the like. For example, a film may be constructed with micropores therein to provide breathability. The micropores form what is often referred to as tortuous pathways through the film. Liquid contacting one side of the film does not have a direct passage through the film. Instead, a network of microporous channels in the film prevents liquids from passing, but allows gases and water vapor to pass. Another type of film that may be used is a nonporous, continuous film, which, because of its molecular structure and thickness, is capable of forming a vapor-pervious barrier. Among the various polymeric films that fall into this type include films made from a sufficient amount of polyester, nylon, poly(vinyl alcohol), polyvinyl acetate, ethylene vinyl alcohol, polyurethane, ethylene methyl acrylate, ethylene methyl acrylic acid, and other films that contain hydrophilic components to make them breathable. Without intending to be held to a particular mechanism of operation, it is believed that films made from such polymers have sufficient levels of water solubility to allow transportation of those molecules from one surface of the film to the other. Accordingly, these films may be sufficiently continuous, i.e., nonporous, to make them liquid-impermeable, but still allow for vapor permeability. These films may be single- or multi-layered, and may be formed by extrusion, solvent casting, and other known techniques. The post-formed may also be stretched to achieve the desired thickness dimension.
Next, the physical structure of glove 2 is described in detail to provide reference for the placement of vapor vents 20 there on. More specifically, glove 2 includes glove back side 8 and glove palm side 10. Glove 2 also includes glove finger portions 12, glove palm portion 16 (having optional flexible gripping areas 14 thereon) and glove wrist portion 18.
Vapor vents 20 provide transition of air and water vapor caused by perspiration of the hand of the wearer of glove 2 to the external environment through vapor vents 20 in exterior layer 4 after the perspiration has passed through interior layer 6 in a vapor state. Vapor vents 20 are preferably mesh in structure and are preferably comprised of a flexible organic polymer that allows movement of the user's hand within glove 2, such as, for example, nylon.
Vapor vents 20 are fixedly secured in exterior layer 4 and are in vapor communication with interior layer 6. Vapor vents 20 are located on portions of glove 2 other than glove palm portion 16 of palm side 10 of glove 2. Keeping glove palm portion 16 of palm side 10 of glove 2 free of vapor vents 20 is an important aspect of the present invention in order to facilitate bending of the palm of the hand of the wearer of glove 2 during use. In this regard, vapor vents 20 are preferably located on glove finger portions 12, and most preferably on each of glove finger portions 12. Vapor vents 20 can also be located on glove back side 8 adjacent wrist portion 18. Locating vapor vents 20 on the glove back side adjacent the wrist portion is an optional placement for the vapor vents and may or may not be used depending on the environmental conditions to which the glove is subjected. Additionally, as best shown in
