MULTI-LAYERED GARMENT
A garment comprising at least two layers, wherein the first layer (1) is a protective shell, the second layer (4) is an insulating layer. The insulating layer (4) has a thickness sufficient to form predefined holes each capable of holding a volume of air.
The present invention relates to garments, more specifically to garments suitable for outdoor use and especially jackets suitable for outdoor use at various levels of activity and weather conditions.
There is a constant need in the market for jackets for outdoor enthusiasts that are truly light weight and comfortable across an extreme spectrum of climates, environments and uses.
At most places, weather shifts quickly, a warm evening can turn suddenly cold, and blue skies can quickly turn to rain. The body's climate can fluctuate at an even faster rate as internal temperature and perspiration levels vary during even moderate physical training. These constantly varying conditions create a need for persons being outdoor to manage his/her own personal climate. Until now persons working out or in other ways being active outdoor, have had to shed layers, bring extra layers, tie jackets around their waist, or toss them to the side in order to deal with the various climates they encounter during an outdoor activity. This effectively encumbers and slows down the outdoor person and especially outdoor athletes, and reduces their performance, comfort, and enjoyment.
The present invention introduces a micro-climate system to provide the wearer an improved capability to regulate their own personal climate, i.e. moisture and temperature, across a variety of outdoor conditions and activities—all within one garment, such as a jacket.
Many types of multilayered garments exist on the market today.
U.S. Pat. No. 4,292,769 describes an anti exposure inflatable structure suit designed for airmen. This structure is designed with spaced inflatable cavities and water vapour openings to prevent water from entering through the structure next to the body. Perspiration can get trapped under the structure next to the body and cannot escape creating an excessively wet environment within the jacket. The suit is breathable only at the outer layer and does not influence the internal moisture or temperature, that is, there is no ability to regulate the micro-climate around the body.
U.S. Pat. No. 7,013,489 describes a light weight jacket with a sealed air polymer cellular thermal layer. It is water impermeable and offers thermal protection and water buoyancy. This garment is multipurpose and intended for nautical work and outdoor use. These designs are intended for extreme climates. However, this solution is not lightweight and is therefore not applicable for a range of physical activities. As it is intended for nautical work, it is not breathable, as moisture will get locked into the suit next to the body, and there is no ability to regulate the micro-climate around the body.
Jackets and outerwear such as the above, are built for use within a specific climate spectrum, e.g. for warm and sometimes rainy weather the jacket should be waterproof and not insulated. In extremely cold and dry weather, the jacket should be heavily insulated and breathable but not water resistant. Jackets have had to be built this way to keep the jacket wearer comfortable when in that specific climate. The ability for a single jacket to provide protection, performance and comfort in a broader range of climates has been limited due to the lack of innovative materials and designs specifically targeting the micro-climate that is created by the body's' natural perspiration and heat generated around the torso.
The term “micro-climate” as it is used here, can be defined by temperature, humidity and airflow around the torso. By regulating the micro-climate around the torso, the jacket wearer can adjust to changing weather conditions as well as activity levels, e.g. more intense activities will introduce more heat and moisture in the micro-climate.
Jackets on the market today have limited versatility, because they have been designed with a specific climate in mind, e.g. the cold/dry jackets would not function well when it's warm/rainy. Because the external climate and the micro-climate within the jacket are constantly changing, the wearer is often either too warm, too cold, or too sweaty, leaving them uncomfortable as there is little opportunity to adjust their micro-climate beyond the traditional means of venting zippers—or simply removing the jacket.
It is an object of the present invention to create a garment such as a jacket that allow the wearer to adjust the micro-climate around the body, and to control his\her personal temperature, airflow and humidity at any given time. This is obtained by a jacket that provides a dramatically and surprisingly expanded range of performance, comfort and versatility.
A jacket according to the invention provides the wearer the ability to adjust the climate (temperature, airflow, humidity) within the jacket via a new design that employs four elements, that when combined, provide an improved range of comfort to consumers. The elements are:
-
- A first layer, preferably in the form of a breathable protective shell. The shell acts as a barrier against the elements (wind & water), while allowing the jacket to “breathe” and release excessive moisture/humidity created by the wearer. Further the protective shell does not have to be breathable, any type of outer shell can be used.
- A mechanical ventilation system that utilizes the natures' elements. This system is designed with air flow ports, on the exterior shell of the jacket that can be opened or shut via zippers to allow the wearer to regulate the flow of air into and through the jacket. If you're cold, you use your body's natural heat generation to warm up. If you're warm, you use natures' elements, that is flowing of cool air, to cool down.
- A second layer, preferably in the form of an insulation layer, for example a fleece layer, that sits next to the exterior shell that features exaggerated air cells, i.e. articulated holes, that vary in size and spacing in the insulation layer in relation to the torso and moisture levels. The exaggerated air cells allow a larger amount of air to be captured and used in combination with the fleece to provide a substantial level of insulation vs. the cold. The exaggerated air cells also allow the wearer to regulate temperature and humidity by engaging the natural flow of air—that enters through the air flow ports to quickly vent and purge the warm air and excess humidity that gets trapped in the exaggerated air cells. The air cells can be of any shape and size.
A third layer, preferably in the form of a mesh liner that is either hung or attached, that separates the insulation layer from the body. The mesh liner provides additional opportunities, to capture insulating air, provide greater air circulation and breathability capabilities, and as a vehicle to transport moisture away from the body.
If the garment does not have a mesh liner the edges of the air cells can be sewn to the outer protective shell.
The micro-climate system according to the invention works as follows. The combination of the above four elements elements allows the jacket wearer to effectively regulate the micro-climate inside the jacket.
When the wearer is cool/cold, e.g. when the wearer is in an inactive situation in a cold environment, the air flow ports are closed completely—no air flows into the jacket, the air is captured in the insulation layer, in the exaggerated air pockets, and in the pockets created by the mesh liner. The wearer gains maximum insulating value from the captured air and effectively regulates the climate within the jacket. Moreover when wearer is cold and air flow ports are closed the wearer maintains better moisture and temperature balance via the windproof/breathable shell.
When the wearer is warm, e.g. when the wearer is engaged in an aerobic or physical situation, the air flow ports are opened to their fullest, the air flow purges the warm/humid air from inside the jacket. The warm/moist air that was captured in the exaggerated air cells is quickly replaced with fresh, cool air that has entered through the air flow ports. The mesh liner facilitates the flow of air around the whole of the interior of the jacket. The combination of air flow ports, exaggerated air pockets and the mesh liner allows this climate adjustment to happen almost instantly.
In all situations, the mesh liner acts as a moisture transport vehicle, wicking the moisture away from the body/next to skin layer.
The invention and terms used in the above will now be further explained by way of the attached drawings of an exemplary embodiment of a garment according to to the invention.
A garment according to the invention is made of a combination of layers having different properties. This is particularly beneficial for the use in jackets, but it can also be used in other garments used outdoor, such as jackets, pants, overalls or one piece suits or in apparel such as tents, emergency shelters, blankets or sleeping bags. In the below description of the drawings, we will refer to a jacket according to one embodiment of the invention, but it will be obvious to the reader is that the description will apply also to any other use of the invention as explained above.
The holes can also be described as exaggerated air cells, varying in size and spacing. The holes are provided throughout the jacket having sizes and patterns adapted to expected amount of moisture and heat generated on various places on the torso. For example, the back side of the jacket form a V in relation to the amount of moisture generated in this area. The holes provided in the insulating layer 4 are substantially larger than what is known from commercially available outdoor jackets at the time of filing, enabling the capture of a larger volume of heated air in the jacket.
The holes can be of any shape, but are preferably round, square or polygonal.
The air cells 5 allow a larger amount of air to be captured and used in combination with the insulating layer to provide a substantial level of insulation vs. the cold. The air cells 5 also allow the wearer to regulate temperature and humidity by venting is and purging the warm air and excess humidity by engaging the air flow ports 3. The insulation layer 4 can for example be made of fleece, woollen fleece, tangled wool or any other material capable of forming a material with a sufficient thickness to form air cells 5.
The jacket 8 according to the invention is provided with a front zipper 9 and air flow ports 3 in the form of zippers. The air flow ports 3 are arranged to be easily reachable for the user of the jacket, see
On the jacket as shown on
Holes 5 forming the exaggerated air cells are provided in the insulating layer 4 on the torso in a predefined pattern, where larger holes are made in areas of the jacket covering areas of the torso more likely to sweat heavily and smaller holes in areas with less sweat. The larger holes will facilitate transportation of sweat away from the torso during heavy workout. If the user is slowing down, the jacket will give an improved insulation of the body as the holes are able to hold a substantial amount of hot air flowing out from the torso, between the exterior shell 6 and the mesh liner. As the back usually emits more heat, it is advantageous to provide larger holes on the back, enabling a more extensive emission of heat and humidity. On the front of the torso, the body emits less sweat and the need for transport of sweat away from the body is less significant, while it is advatageous to isolate the inner organs by minimising the flow of air away from the body. To reflect this, it is advantegeous to have fewer and, if this is found profitable, smaller holes 5.
The presentation in
In one example of the embodiment, the larger holes are about 30 mm in diameter, the medium sized holes are about 20 mm in diameter and the smaller holes are about 13 mm in diameter. In other embodiments, not shown here, other dimensions can be used.
The suit according to an embodiment of the invention is provided with an exterior breathable shell 6 and a front zipper 9, as shown on
Garments according to the present invention has a number of advantages over other garments in the marketplace. The air flow ports is a simple and efficient mechanical ventilation system that uses natures' elements. The exaggerated air cells in a fleece fabric provide a substantially larger ability to hold air in the layers of a garment. The micro-climate system according to the invention presents a unique combination of a protective shell, air flow ports, exaggerated air cells in a fleece material and a mesh liner.
While the best effects of micro-climate control will be realized while combining all four elements, it is possible to combine some of the elements in unique combinations to deliver similar results.
It is also conceivable that a garment according to the invention can be realized through other elements that would provide enhanced insulation properties and increased air flow such as other combinations of insulation and air pockets, other synthetics, down, etc, combinations of air flow ports, insulation and exaggerated air pockets or liners that enhance air flow while providing exaggerated air pockets for insulation. However, for the garment or apparel according to the invention to work in an efficient manner, the garment should be provided with at least one breathing layer, at least one insulating layer being able of forming air cells having the properties described above and preferably at least one layer being able of transporting humidity and to some extent hold air inside the air cells of the insulating layer.
The outermost breathable layer can be a simple textile functioning as a windstopper. It can also be a more advanced material also providing water repellent and/or vapour permeable properties. In some applications of the invention, it is beneficial to provide an outermost layer including several layers, for example a textile covered with one or more membranes with different properties or a layer where one or more textiles are adhedered to each other with or without one or more membranes.
This invention can be broadened to provide similar benefits in other applications such as technical outerwear, e.g. insulated jacket and pants, uninsulated jackets and pants, as normal outerwear, e.g. jackets and pants, as mid-layers in jackets, pants and one piece suits, as base-layers in underwear, jackets and pants, as sportswear such as jackets, shirts and pants. It can also be applied to gloves, hats and footwear or infant apparel, such as playsuits, outerwear, hats, gloves, booties and one-piece bodysuits.
Furthermore, the concept could be adapted for use beyond apparel in areas such as tents, emergency shelters, blankets or sleeping bags.
