10206443
The disclosure relates in general to camouflage patterns and methods of making the same, and more particularly to camouflage patterns having multiple microterrain pattern zones.
Camouflage techniques are used to obscure objects for the purpose of decreasing or preventing detection. One camouflage technique involves constructing objects having certain surface patterns. These patterns are designed to blend into the environment and conceal the object from visual detection.
Camouflage patterns were initially developed for military applications in WWI to conceal troops and equipment from detection by enemy forces. Eventually, the use of camouflage spread to civilian use as hunters recognized the benefits of camouflage to conceal themselves and their equipment from wildlife. Other outdoor enthusiasts, such as paint ball players, bird watchers, and other nature enthusiasts also commonly use camouflage.
Initially, camouflage patterns used by hunters were similar to the early military patterns of randomly arranged colored splotches. Later, as printing and photography techniques improved, camouflage patterns were developed that incorporated the colors and imagery of a particular environment. As a result, camouflage patterns moved from simple patterns having only a handful of color variations, generally green, brown, or grey, to a wide assortment of patterns targeted to a particular environment and even to a particular season. For example, a camouflage pattern designed for a timber forest in the fall season may contain elements having brown, orange, and yellow. In contrast, a camouflage pattern designed for a timber forest in the winter season may contain elements having brown and white.
Many modern camouflage patterns include photorealistic images of a particular environment. These patterns generally contain high quality images of a single perspective of the vegetation and/or background flora and fauna. These patterns are most effective in concealing a hunter when the perspective displayed in the pattern matches the perspective in the surrounding environment (i.e., the background and/or foreground).
For example, a photorealistic pattern including reed stalks is most effective when the hunter is standing amongst reed stalks. These patterns, however, lose their effectiveness when the hunter moves to a nearby location having a different type of vegetation in which reed stalks are not prevalent. In that situation, the reed stalk pattern causes the hunter to stand-out, rather than blend into his or her surroundings.
Accordingly, patterns that mimic a specific environment with high detail, as do many photorealistic patterns, are inherently less suited to other environments or even to different areas within a target environment.
Accordingly, it would be an advance in the state of the art to provide a camouflage pattern for outdoor garments and hunting equipment that is highly effective in obscuring an individual across a range of microterrains within a larger target environment.
In one embodiment, a camouflage system includes a camouflage surface having a plurality of segments. The camouflage surface includes a first pattern disposed on a first segment of the plurality of segments, the first pattern comprising a depiction of a first microterrain of a natural environment, a second pattern disposed on a second segment of the plurality of segments, the second pattern comprising a depiction of a second microterrain of the natural environment, and a third pattern disposed on a third segment of the plurality of segments, the third pattern comprising a depiction of a third microterrain of the natural environment. The first microterrain differs from the second microterrain and the second microterrain differs from the third microterrain.
In another embodiment, a camouflage system including a surface including a first pattern disposed on a first portion of the surface. The first pattern includes a depiction of a first position of a first microterrain of a natural environment. The surface includes a second pattern disposed on a second portion of the surface. The second pattern includes a depiction of at least one of the first microterrain and a second microterrain of the natural environment.
In another embodiment, a method of creating a camouflage fabric is presented. The method comprises applying to a fabric a first microterrain pattern extending in a first direction along the fabric, a second microterrain pattern extending in the first direction along the fabric, a third microterrain pattern extending in the first direction along the fabric, a first transition region between the first microterrain pattern and the second microterrain pattern, and a second transition region between the second microterrain pattern and the third microterrain pattern. The method includes cutting a plurality of segments from the fabric, wherein the plurality of segments are randomly selected to include at least a portion of each of the first microterrain pattern, the second microterrain pattern, and the third microterrain pattern, and joining at least two of the plurality of segments.
The invention will be more fully understood by referring to the following Detailed Description of Specific Embodiments in conjunction with the Drawings, of which:
The invention is described in preferred embodiments in the following description with reference to the Figures, in which like numerals represent the same or similar elements. Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.
Referring to
Within a particular target environment, a camouflage pattern mimicking any one of images 104, 108, or 112 will be highly effective at obscuring an object when viewed in a microterrain having the vegetation depicted in the image 104, 108, or 112, respectively. However, when viewed in a different region of the landscape (that is, within a different microterrain), having different vegetation, such as when camouflage depicting the cattails of image 104 is worn in a region having a microterrain predominated by the grasses of image 108, or the vegetation of image 112, the obscuring capability of the camouflage is severely reduced or, in extreme cases, completely eliminated. In some scenarios, such a mismatch in appearance, even between microterrains of a particular target environment, will cause the camouflage to highlight, as opposed to obscure, an object.
This can be particularly problematic as a hunter, or other individual wearing camouflage, is very likely to move about within a particular area. If the camouflage is narrowly suited to only a single microterrain of the area, as the individual moves about the area, potentially passing through a number of other microterrains, the camouflage's effectiveness will be severely reduced when the camouflage is present within those other microterrains.
Nearly every possible terrain in which camouflage may be utilized incorporates a number of different microterrains. In a city, for example, where law enforcement or the military may require camouflage, microterrains may include those predominated by buildings, vehicles, or park foliage. In a general hunting environment, different microterrains may be predominated by conifer trees, hardwood trees, grass, and water, for example. When utilizing camouflage within a particular target environment, it is generally always possible to identify a number of different microterrains that each have an overall appearance that are markedly different from one another. The difference in appearance between microterrains can make the design of camouflage difficult, as the camouflage must perform equally well in all microterrains. Camouflage that is only satisfactory for a single microterrain may become entirely inoperable when the camouflage is positioned in a different microterrain that may be only feet away.
Without limitation, a microterrain may include a common type of environment identified within a particular target area, such as a sage or sagebrush environment, a grass or grassy plain environment, a leaf environment, a woodlands environment, a brush environment, a rock environment, a pine environment, a marsh environment, or a desert or desert plain environment. The visual attributes of a particular microterrain of a target environment may also be affected by a season in which the microterrain may be depicted. For example, a microterrain of a “fall season” woodlands environment depiction may contain leaves, for example, having brown, orange, red and other fall colors; a microterrain of a “winter season” woodlands environment may contain, for example, bare trees with no leaves and white snow; and a microterrain of a “summer season” woodlands environment may contain, for example, green leaves with little or no twigs or bark. Additionally, the visual attributes of a given environment may vary even within a particular microterrain. For example, within a particular woodland microterrain containing, for example, particular types of trees, different visual attributes may be present when viewing the microterrain from different positions, such as a height of 6 feet (wherein the visual attributes would be predominated by tree trunk structures), a height of 14 feet (wherein the visual attributes would be predominated by tree limbs and thicker branches), and a height of 22 feet (wherein the visual attributes would be predominated by thin branches and leaves). Similarly, a micro terrain including corn stalks may have different visual attributes, such as disc corn, stubble corn, and/or standing corn. Accordingly, it is explicitly contemplated in the present disclosure that different positions within a microterrain (referred to herein as micropositions), though occupying the same approximate location and belonging to the same microterrain, may have different visual attributes and that those different visual attributes may be utilized in generating a camouflage pattern in accordance with the present disclosures. In various implementations, a single camouflage pattern configured in accordance with the present disclosure may depict a number of different micropositions within the same microterrains. Alternatively, a camouflage pattern may be generated depicting a number of micropositions selected from a number of different microterrains.
The present system and method, therefore, provides for the creation of camouflage that incorporates elements from a plurality of microterrains (and, potentially, micropositions of those microterrains) of a particular target geographical region. By depicting a number of microterrains and micropositions, the resulting camouflage can be utilized to provide an obscuring function in a number of different microterrains that are likely to be present within the target geographical region. In one implementation of the present system, various zones of a camouflage pattern may predominantly depict elements from a particular microterrain, as described below. In some cases, to facilitate blending between the different zones of the camouflage pattern, a zone that is targeted towards depicting elements from a first microterrain, may depict a small number of elements from other microterrains. This blending can serve to soften the borders between the different regions of the fabric where the different microterrain elements are depicted.
The present camouflage system can be utilized to generate camouflage patterns that may be utilized in conjunction with any clothing, equipment, or object to which the camouflage pattern is to be applied. In the present disclosure, a number of examples describe the present system in terms of camouflage clothing. However, it is to be understood that the present camouflage system may be utilized to camouflage non-clothing objects, such as weapons, hunting equipment, camping equipment, footwear, and the like.

In the example depicted in
The arrangement of the camouflage patterns 104, 108, and 112 on the clothing set 200 each operate to obscure a different portion of the clothing set, depending upon the microterrain in which the hunter is present. When worn by a hunter standing in or near a microterrain predominated by cattails and reeds, for example, the zone 206 configured with the first pattern 104 effectively obscures the hunter's feet and lower legs. Likewise, the zone 208 configured with the second pattern 108 effectively obscures that portion of the hunter when the hunter stand in a microterrain predominated by grasses. Finally, the zone 210 configured with the third microterrain pattern 112 effectively obscures that portion of the hunter when the hunter stands in a microterrain predominated by that type of vegetation. It should be noted that, with respect to the garment depicted in
Unlike prior art camouflage, which is generally consistent from head to toe, the present camouflage comprises multiple zones, each zone being tailored to specific types of microterrains that may be encountered by a hunter on a particular trip or series of outings, where the series of trips may lead the hunter to multiple microterrains in multiple seasons, for example. The zones are selected and configured to provide enhanced obscuring performance when in the field. In certain embodiments, the zones are distinguished from one another by the types of vegetation predominantly displayed within the zone, where the vegetation is associated with a particular microterrain (or microposition) of a target geographic region.
When in the field, hunters are generally visible from a variety of different locations because they move across different areas and assume different positions, such as crouching, kneeling, sitting, and standing, in one trip, or from trip to trip. While traditional camouflage will effectively obscure a hunter primarily in one location (and presuming that the hunter's camouflage is matched to that location), the clothing set 200 is, in one embodiment, designed to effectively obscure at least one portion of the hunter at all times in a number of microterrains within a larger target environment (e.g., a wetlands environment). This results in at least a portion of the body being hidden from view and, thereby, the breaking up and obscuring of the hunter's human form. In different scenarios, depending on the background and foreground perspectives, only one of zones 206, 208, and 210 may be fully obscured. While only a portion of the hunter is obscured, the shape of the human body is broken up and hidden. By hiding the human form, the present camouflage hides the pattern that alerts animals.

In one embodiment, the jacket and pants of clothing sets 200, 300, 400, and 500 are configured as distinct garments. In another embodiment, the jacket and pants of clothing sets 200, 300, 400, and 500 are configured as a single garment. In one embodiment, the clothing sets 200, 300, 400, and 500 consist of a jacket only. In one embodiment, the clothing sets 200, 300, 400, and 500 consist of a pair of pants only. In one embodiment, the clothing sets 200, 300, 400, and 500 consist of one or more of a jacket, a pair of pants, a hat, a pair of gloves, and a scarf.
In one embodiment, the patterns on clothing sets 200, 300, 400, and 500 that mimic images 104, 108, 112, and 318 can be photorealistic images. In one embodiment, the patterns on clothing sets 200, 300, 400, and 500 that mimic the microterrains of images 104, 108, 112, and 318 can be semi-photorealistic images, such as drawings, sketches, or other artistic renderings designed to replicate, mimic, or intimate the visual attributes of a particular microterrain or microposition within a microterrain. In one embodiment, the patterns on clothing sets 200, 300, 400, and 500 that mimic the microterrains of images 104, 108, 112, and 318 can be a combination of photorealistic images and semi-photorealistic images that may depict a particular scene or a collection of artifacts from a particular microterrain or microposition within a microterrain. As used herein, photorealistic means high resolution, photo quality, lifelike images where details smaller than ¼ inch can be discerned. As used herein, semi-photorealistic means medium resolution images where only features greater than ¼ inch can be discerned. In other implementations, though, non photorealistic or semi-photorealistic images may be utilized. In that case, the patterns, although not depicting specific objects or items, may include patterns and/or shapes that are tailored to mimic elements or scenes from a particular microterrain.
In one embodiment, the patterns on clothing sets 200, 300, 400, and 500 that mimic the microterrain of images 104, 108, 112, and 318 are configured on the clothing set by printing. In various embodiments, the patterns are configured by screen printing, roller printing, air brushing, jet printing, digital printing, block print, or any other suitable printing technologies, or a combination thereof.
In one embodiment, the patterns on clothing sets 200, 300, 400, and 500 that mimic images 104, 108, 112, and 318 are configured on the clothing set by attaching a synthetic layer printed with the pattern to the garment material that forms the clothing set.
In one embodiment, the patterns on clothing sets 200, 300, 400, and 500 that mimic the microterrain of images 104, 108, 112, and 318 are all formed on a single, continuous piece of fabric, cut, and formed into a clothing set. In another embodiment, the different patterns, mimicking the microterrains of images 104, 108, 112, or 318, are each printed on a separate piece of fabric, cut, and combined to form a clothing set.

Multiple images or patterns, each depicting or representative of a microterrain within the target environment, are captured from the target environment at step 1004. In general, the multiple images or patterns will depict or represent prominent microterrains or micropositions within the larger, target environment. When the target environment is wetlands, for example, the microterrains may include those predominated by cattails and/or reeds nearby a lake, stream, or other body of water, grasses, and fencerows of vegetation. Alternatively, when the target environment is an urban environment, the microterrains may be predominated by portions of a building, elements of one or more cars, trucks, or other vehicles, elements from a city park or landscaping around a building, and the like. Generally, the microterrains represent common visual scenes likely to be found in a particular target environment. Depending upon the implementation, a single image or representation of the target environment may be captured or generated and then subdivided to generate the multiple images or patterns of step 1004. Alternatively, a plurality of separate images or patterns may be captured or generated to depict each of the target environment's microterrains.
In some cases, a secondary environment to the original target environment is also identified at step 1006. The secondary environment is generally different from the target environment. In various embodiments, the secondary embodiment can be wetlands, woodlands, western plains, or urban environments.
If a secondary environment is identified, an image, representation, or pattern is captured or generated from the secondary environment from a microterrain thereof at step 1008. Alternatively, multiple images or patterns may be captured or generated from the secondary environment, each depicting different microterrains or micropositions within a microterrain.
A pattern is created from each image or pattern of the target and secondary environments (if a secondary environment is utilized) at step 1010. Once the patterns for each image are created, the individual patterns are joined together to form a camouflage pattern in step 1011 that includes elements from each individual pattern. As such, the final camouflage pattern will include images, patterns, or representations of a number of different microterrains and/or different micropositions within one or more microterrains. The camouflage pattern is then printed on a substrate at step 1012. In one embodiment, the pattern is printed by screen printing, roller printing, air brushing, jet printing, or digital textile printing. In different embodiments, the substrate is the material used to form a garment, attached to the material used to form a garment, is applied to other objects, such as weapons, tents, backpacks, binoculars, or other outdoor equipment, or is attached to the surface of a hunting accessory.
The substrate is incorporated into an article at step 1014. In various embodiments, the substrate is incorporated into a garment, tent, hunting accessory, vehicle, structure, building, or any other item to be obscured. The method ends at step 1016.
In certain embodiments, when constructing a camouflage garment, the garment is cut from a single length of fabric, where the fabric comprises at least 3 distinct zones depicting microterrains of a particular target environment or different micropositions within one or more microterrains. Each zone can be an image or other representation of elements found in a particular microterrain within the target environment. A microterrain type may be, without limitation, a common type of scene identified within a larger environment, such as a sage scene, a grass scene, a leaf scene, a woodlands scene, a brush scene, a rock scene, a pine scene, a marsh scene, or a desert scene. The visual attributes of a particular microterrain of a target environment may also be affected by a season in which the microterrain may be depicted or the micropositions within the microterrain. For example, a “fall season” woodlands microterrain depiction may contain leaves, for example, having brown, orange, red and other fall colors; a “winter season” woodlands microterrain depiction may contain, for example, bare trees with no leaves and white snow; and a “summer season” woodlands microterrain depiction may contain, for example, green leaves with little or no twigs or bark. Similarly, different micropositions within a microterrain may have different visual attributes.
Referring to
In the depicted embodiment, the section 1100 includes 4 distinct patterns or zones (1102, 1104, 1106, 1108) that run along the section 1100. In other embodiments, the section 1100 contains 3 to 6 patterns or zones depicting different microterrains that run along the section 1100. In one embodiment, the patterns are equal widths. In other embodiments, the width of one terrain pattern is greater than the width of another terrain pattern.
In one embodiment, each pattern depicts a different microterrain of a larger, target environment. For example, terrain pattern 1102 may be an image of a first microterrain predominated by a first type of vegetation, terrain pattern 1104 may be an image of a second microterrain predominated by a second type of vegetation, terrain pattern 1106 may be an image of a third microterrain predominated by a third type of vegetation, and terrain pattern 1108 may be an image of a fourth microterrain predominated by a fourth type of vegetation. In other embodiments, terrain pattern 1102, 1104, 1106 and 1108 may depict any combination of microterrain from a particular target environment.
In one embodiment, each terrain pattern seamlessly transitions into the adjacent terrain pattern. For example, terrain pattern 1102 seamlessly transitions into terrain pattern 1104 at transition region 1112, terrain pattern 1104 seamlessly transitions into terrain pattern 1106 at transition region 1114, terrain pattern 1106 transitions into terrain pattern 1108 at transition region 1116. For purposes of clarity, a seamless transition means that one terrain pattern transitions, or blends, into the next without a discernible break, line or seam. In other words, if terrain pattern 1102 depicts a sage microterrain and terrain pattern 1104 depicts a grass microterrain, transition region 1112 will contain both sage elements and grass elements. The portion of the transition region 1112 adjacent to the terrain pattern 1102 will contain primarily sage elements and the portion of the transition region 1112 adjacent to the terrain pattern 1104 will contain primarily grass elements. The center of the transition region 1112 will contain an equal mix of sage and grass elements. In this way, the smooth transition between terrain pattern 1102 and terrain pattern 1104 across transition region 1112 seamlessly blends the two terrain patterns together.
In various embodiments, the transition region is between about 2 inches and about 18 inches. In one embodiment, the transition region is about 8 inches. In one embodiment, the transition region is about 6 inches. In one embodiment, the transition region is about 4 inches.
In one embodiment, the image is seamless along the entire physical length of the fabric, of which section 1100 is a portion. In other words, the pattern continues along the entire physical length of the fabric without a discernible break, line or seam. In one embodiment, the pattern repeats along the length of the fabric. The pattern seamlessly transitions between each repeat segment.
In other implementations, however, transition between patterns (e.g., terrain patterns 1102, 1104, 1106, and 1108) are abrupt with no transition region present between the patterns.
The section 1100 may be created by screen printing, roller printing, air brushing, jet printing, digital printing, any other fabric printing technologies, or a combination thereof.
In another implementation, each microterrain pattern includes elements from the other microterrains being depicted in the camouflage patterns.
As depicted in
In one implementation, the depicted elements in each zone (e.g., zones 1152, 1154, and 1156) in camouflage pattern 1150 are selected to include 10% of the elements from the other microterrains in the camouflage pattern 1150 and the remaining elements from the target microterrain. Accordingly, in pattern 1150, zone 1152 will include 80% of its elements from the sage brush microterrain, 10% of its elements from the long grass microterrain, and 10% of its elements from the foliage microterrain. This approach ensures that each zone in a particular camouflage pattern is predominated by elements from a particular microterrain, but includes some elements from the other depicted microterrains.
In some cases, these percentages can be adjusted so that in a particular pattern, zones that are further away from one another include fewer elements from one another, whereas zones that are more proximate to one another may share a greater number of elements.

In various embodiments, multiple print assemblies 1214 are used to print an image on the fabric 1206. Each print assembly comprises a pressure roller, a print roller, and a reservoir. A print assembly may be provided for each color to be applied to the fabric. In some embodiments, between 2 to 6 print assemblies 1214 are used to apply the image to the fabric.
Referring to
In one embodiment, the surface of the print roller 1210 comprises copper etched with the patterns to be printed. In one embodiment, the diameter of the print roller is between 4 and 18 inches. In one embodiment, the diameter of the print roller is about 8 1/32 inches.
Garment segments are cut from the fabric after the terrain patterns have been applied to the fabric. Referring to
As the various garment segments are cut from the fabric 1506, the segments are cut from different offsets of the repeat pattern. For example, for the legs sections cut from terrain pattern 1102, the offset on the repeat pattern results in a different pattern on each segment depicted in
Referring to
In this embodiment, each garment segment type (legs, left arm, right arm, body) is each cut from at least two terrain patterns. For example, the pant legs 1604 are cut from various locations that cover, in different instances, all four terrain patterns. In this embodiment, at least 3 terrain patterns will be included in each pant leg 1606. The location of each segment 1604 is shifted to cover different microterrain patterns. The combination of the four microterrain patterns, 1102, 1104, 1106, and 1108, with the repeat pattern results in garment segments that comprise a combination of microterrain patterns and with a highly unique pattern.
In other implementations, the location and orientation of each segment or portion of a clothing item that may be cut from the fabric may be randomized or varied according to a suitable positioning algorithm. The randomization (or positioning algorithm) can be selected to ensure that each portion of a particular clothing garment (e.g., pant leg 1606, arm, chest, or collar) includes a varying amount of one or more of the available microterrains on the fabric. As such, each portion of a garment (e.g., the legs, arms, chest, or collar) can include not only a different number of microterrain patterns (e.g., one or more), but also a varying amount of each microterrain pattern. A similar variation in pattern could be achieved, for example, by cutting the portions of the garment from an underlying camouflage pattern wherein the pattern depicted thereon is at least somewhat randomized (see, for example, the pattern depicted in
Referring to
Additional transition regions at the ends of each repeat section are created at step 1710 if desired. These transition regions seamlessly blend the end of one repeat segment with the beginning of the next repeat segment if desired. The size of a repeat segment matches the size of the print roller used to apply the repeat segment to fabric, where the length of a repeat segment is equal to the circumference of the print roller and the width of the repeat segment is equal to the printable width of the roller. In one embodiment, the repeat segment is etched into the copper surface of the print roller. In other embodiments, the repeat segment is loaded into a computer-controlled print system of an ink jet fabric printing system.
The repeat segment is printed repeatedly and continuously onto a length of fabric at step 1712. Garment segments are cut out of the printed fabric at step 1714. In one embodiment, the garment segments cut from the fabric comprise a full garment such that the garment comprises a pattern corresponding to every microterrain of the plurality of microterrains originally selected. The method ends at step 1716.
