Definitions
- the invention relates to windproof and waterproof clothing when used by persons who are engaged in active pursuits, such as those involving either work or recreation. Specifically this invention relates to a method for protecting persons from the negative effects of wind or rain, while simultaneously providing means for the hot, moist air generated by their body to vent to the exterior of their clothes so that the vapor doesn't condense inside their clothes and make them wet.
- This problem has been recognized and ventilation systems have been created for clothing that can be opened by various means such as zippers, however in the event of rain these vents must be closed to prevent water from entering into the clothing from the outside and then the moist air created by the body condenses on the interior of the clothing.
- Waterproof clothing has until the present time been constructed either from coated fabric such that it is absolutely windproof and waterproof, or from fabric with a membrane that keeps water (such as rain) from penetrating the fabric from the exterior but which is, to some degree, permeable to vapor such as that created by the human body under exertion.
- neither material allows substantial amounts of heat or moisture to move from the interior to the exterior of clothing constructed from the material. The result is that heat and moisture will accumulate within a very short time when the user is active. This in turn results in overheating, a drop in performance, and the wearer becoming wet from moisture condensing inside the clothing.
- clothing as used in the description of the present invention relates to jackets, trousers, shirts, and headgear.
- Japanese Patent No. 2008038323 Fukuyama Teruyoshi discloses a similar shingled construction to create ventilation, but suffers from the same drawbacks as Jaeger.
- the prior-art techniques attempt to prevent the intrusion of water while allowing for the venting of vapor.
- the prior methods have a number of disadvantages: a) the construction costs of creating the vents using elaborate combinations of materials are prohibitive; b) the shingled construction with multiple layers of materials creates added bulk that feels awkward and constrains movement; c) the amount of air flow through the vents is limited by the various meshes it has to pass through; and d) the designs limit the range of materials that can used to create the clothing.
- JP H09 31728 A discloses a ventilating implement having a plate-like mount attached to a clothing article so as to stop up a vent hole formed in the clothing article.

- CN 201 349 559 Y relates to clothes having apertures and a vent assembly for each aperture.
- US 4 270 227 A teaches an air vent for incorporation in rain-wear comprising a base portion having a hole therein and an elongate member having a passage therethrough in communication with the hole.
- an outerwear clothing article is disclosed having at least one vent forming a passage through the outer shell of the article.
- the vent may have a closure element for selectively restricting a flow through the vent.
- the present disclosure relates to windproof and waterproof clothing for use by persons who are engaged in active pursuits involving either work or recreation as well as other applications in which both waterproofing and breathability are important.
- the present disclosure is related to an apparatus including at least one panel defining one or more apertures and including a flexible material.
- One or more vent assemblies are secured to the at least one panel for each aperture of the one or more apertures.
- Each vent assembly includes a base portion secured to the at least one panel and defining an opening overlapping the each aperture.
- An outer ridge is secured to the base portion and an inner ridge secured to the base portion, the inner ridge being encircled by the outer ridge.
- a cap is secured to the base portion and has an outer perimeter positioned between the inner ridge and the outer ridge, the cap, inner ridge, and outer ridge defining a channel in fluid communication with the opening.
- the base may include a flange for bonding to the panel.
- the outer ridge defines one or more notches, which may be non-uniformly distributed around the outer ridge.
- the outer ridge may extend outwardly from the base more than the inner ridge.
- the perimeter of the cap may be offset from the base a distance less than the extent of the outer ridge outwardly from the base.
- the base defines a plurality of receptacles and the cap has a plurality of posts secured thereto and sized to insert within the receptacles.
- the end portions of the plurality of posts may include a widened portion configured to resist removal of the end portions from the receptacles.

The result is that heat and moisture will accumulate within a very short time when the user is active. This in turn results in overheating, a drop in performance, and the wearer becoming wet from moisture condensing inside the clothing. Conversely in a colder environment, the wearer sweats during active times then the dampness remaining on the wearer's body over chills the body during rest periods. The term clothing as used in the description of the present invention relates to jackets, trousers, shirts, and headgear.
- Other methods have been developed to allow for the venting of wind and waterproof clothing while preventing the intrusion of rain.
US Pat. No. 7,043,767 to Jaeger discloses a ventilation system for clothing utilizing a shingled construction. However, this system is expensive to construct and is very limited in the range of materials that can be used. - Similarly, Japanese Patent No.
2008038323 Fukuyama Teruyoshi - Another method of allowing for ventilation while preventing rain from penetrating is
US Patent Application Publication No. 2010/242149 to Mickle et al. , which discloses a series of vents using spacer materials as baffles to allow air flow while keeping rain water out. This approach, however, is expensive to construct, can only use a limited range of materials and is bulky. - The prior-art techniques attempt to prevent the intrusion of water while allowing for the venting of vapor. But the prior methods have a number of disadvantages: a) the construction costs of creating the vents using elaborate combinations of materials are prohibitive; b) the shingled construction with multiple layers of materials creates added bulk that feels awkward and constrains movement; c) the amount of air flow through the vents is limited by the various meshes it has to pass through; and d) the designs limit the range of materials that can used to create the clothing.

Thevent assembly 30 may secure to a garment or some other device by means of thebase plate 36. -
Fig. 12A and Fig. 12B illustrate thebase portion 32 of thevent assembly 30. Thebase portion 32 may define anouter ridge 38 and aninner ridge 40. Theouter ridge 38 encircles theinner ridge 40. Theridges gutter portion 42. Theridges gutter portion 42. Thegutter portion 42 may be defined as a portion of thebase plate 36 positioned between theridges ridges base plate 36 all have a circular perimeter shape. However, other perimeter shapes may also be used. In the illustrated embodiment, theouter ridge 38 defines one ormore grooves 44 to facilitate drainage of fluids that may collect in thegutter portion 42. Thegrooves 44 may be distributed non-uniformly around theouter ridge 38. For example, thegrooves 44 may only be present in one half of theouter ridge 38. In this manner the un-grooved portion of theouter ridge 38 may be positioned vertically above the grooved portion thereby allowing water to drain from thegutter portion 42 but hindering falling water from entering thegutter portion 42. - As will be described in greater detail below, the
upper portion 34 may mount to the lower portion by means ofreceivers 46 secured to thebase plate 36.

Theaperture 48 is preferably large, e.g. have a diameter larger than 50%, preferably larger than 75%, of the diamter of theouter ridge 38. In the illustrated embodiment, theouter ridge 38 andinner ridge 40 are concentric with each other and theaperture 48 and thereceivers 46 protrude into theaperture 48. However, other configurations may also be used, including eccentric configurations. -
Fig. 13A and Fig. 13B illustrate theupper portion 34 of thevent assembly 30. Theupper portion 34 may define anouter cover 50 that provides a continuous waterpoof area within aperimeter 52. Thecover 50 may haveposts 54 or some other fastening structure extending from a lower surface thereof to enable securement of thecover 50 to thebase portion 32. Theposts 54 may protrude from theouter cover 50 or frompedestals 56 or some other structure secured to a lower surface of thecover 50. - Referring to
Fig. 14 , in the illustrated embodiment, theposts 54 may be inserted into thereceivers 46 in order to fasten theupper portion 34 to thelower portion 32. Theposts 54 may be secured within thereceivers 56 by means of adhesives, an interference fit, or some other means. In the illustrated embodiment, theposts 54 have a wideneddistal portion 58. During insertion one or both of thedistal portion 58 and thereceiver 46 may elastically deform. When thedistal portion 58 emerges from thereceiver 46, one or both of thedistal portion 58 andreceiver 46 may elastically return to approximately their original dimensions such that the wideneddistal portion 58 will resist removal of theposts 54 from wtihin thereceivers 46. In the illustrated embodiment, thereceivers 46 have a tapered, e.g. conical, shape to facilitate insertion of the widened portion. Thereceivers 46 may be formed in amember 60 that protrudes into theaperture 48. When theposts 54 are inserted within thereceivers 46, thepedestals 56 may abut themembers 60. - The
base plate 36 may define aflange 62 extending radially outward therefrom enabling securement of thevent assembly 30 to asheet 64 of material defining an aperture for receiving thevent assembly 30. In the illustrated configuration theflange 62 secures to an inner surface of thesheet 64 and theridges sheet 64 and extend outwardly from an outer surface of thesheet 64. However, other configurations are possible. For example, the lower surface of theflange 62, and additionally or alternatively other areas of thebase plate 36, could secure to the outer surface of thesheet 64. In such embodiments, thesheet 64 may define an aperture that overlaps with theaperture 48 when the vent assembly is installed. - In any of these configurations, the
base plate 36 may secure to thesheet 64 by means of adhesives, stitching, welds (e.g. high frequency or radio frequency welds), or some other bonding technique. Thelower portion 32 andupper portion 34 may be formed of a rigid material or a flexible material. For example, where thevent assembly 30 is incorporated into a garment aflexible vent assembly 30 may facilitate movement of the wearer and reduce the likelihood of thevent assembly 30 tearing out of the garment. However,vent assemblies 30 including a rigid or semirigid material may also be suitable for many applications. Even with a rigid material, thevent assembly 30 can function well with a flexible material in a garment, for example. The vents may be small enough that when strategically placed they do not interfere with movement and comfort. Thevent assembly 30 may be constructed of vinyl, coated urethane, polyvinyl chloride (PVC), or other polymer materials. - The
sheet 64 may be a breathable or non-breathable material. Thevent assembly 30 is particularly useful with materials that are waterproof but not breathable inasmuch as these materials are less expensive than breathable materials. Thesheet 64 may be a flexible material, however rigid and semirigid materials may also be used as thesheet 64. - Referring to
Fig. 15 , theinner ridge 40 has aheight 66, theouter ridge 38 has aheight 68, and theperimeter portion 52 of thecover 50 has an offsetdistance 70 relative to a deepest point of thegutter portion 42. As shown, theheight 68 may be greater than the offsetdistance 70 such that theouter ridge 68 is able to hinder ingress of water under thecover 50. Theheight 66 of theinner ridge 40 may be such that there is a gap between the lower surface of thecover 50 and theinner ridge 40. There may likewise be a circumferential gap between theperimeter 52 of thecover 30 and theouter ridge 38. In this manner,air flow 72 is permitted through theaperture 48, between theinner ridge 40 and thecover 50, and through the gap between theouter ridge 38 and theperimeter 52. - Referring to
Fig. 16 , agarment 74, such as a jacket, windbreaker, pants, or the like may incorporatevent assemblies 30 as described hereinabove in one or more panels of material forming thegarment 74. For example, a garment may includeupper vents 76 andlower vents 78 such that theupper vents 76 are higher than thelower vents 78 when thegarment 74 is worn by a person standing upright. In this manner, convection will tend to draw air through thelower vents 78 and expell air through the higher vents 76. Vents may be placed at other strategic areas, such asvents 80 placed in the armpit area of thegarment 74. As noted herein, eachvent - Referring to
Fig. 17 , in other applications,vent assemblies 30 may be incorporated into atent 82, such as a single-walled tent. In single-walled tents, a single layer of material must provide both a waterproof covering and permit venting for breathing and to reduce condensation on the inner surface of the tent. Accordingly, a panel of thetent 82 may havevents vents vent assembly 30 described herein. As for the embodiment ofFig. 16 , thetent 82 may includeupper vents 84 andlower vents 86 positioned such that theupper vents 84 are vertically above thelower vents 86 when the tent is set up, thereby promoting venting due to convection. - While the preferred embodiments of the invention have been illustrated and described, as noted above, many changes can be made. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
