## Background
This application claims the benefit of U.S. provisional application No. 61/867,341, filed Aug. 19, 2013, which is incorporated herein by reference in its entirety.


FIELD OF THE TECHNOLOGY
The present disclosure relates generally to anchor systems, and more particularly to improved shelters and shelter anchor assemblies.
BACKGROUND
Shelters, tents, rapid-deployment shelters, forts and the like typically include sheets of fabric, or other materials, secured to a frame. Often these units are free-standing or are similarly semi-attached to a ground surface or tangential fixture. Typically, guy ropes help anchor the unit to a ground surface. However, positioning the guy ropes on a surface is often a difficult and demanding task, particularly during emergency situations and in uncertain environmental conditions. Further, maintaining a secured and taught connection between the unit and the guy rope to hold the assembly in place is also difficult in demanding environments.
For instance, rapid tactical shelters are used in a variety of demanding on-site scenarios including fire, incident command, communication areas, crime scene investigation, flu vaccination, military deployment and other on-site emergency response spots in a variety of challenging terrains, and environmental conditions. Rapid deployment, with quick and easy set-up and take-down, and securing of such units is often beneficial, if not necessary. Conventional roping, tent pegging, and weight anchor systems have been used to position such units, but these conventional systems fail to provide the simple, rapid, efficient and secure anchor that is needed in these situations. Deployment situations may be, for example, on concrete where pegs are not penetrable, on uneven surfaces or in barren places devoid of structures on which to secure roping and/or at remote locations making transportation of weights impractical.
Therefore, Applicants desire systems and methods for anchor systems and deployment shelters without the drawbacks presented by the traditional systems and methods.
SUMMARY
In accordance with the present disclosure, anchor systems and shelter assembles are provided for securing shelters, forts deployment tents and the like. This disclosure provides an improved anchor system that is convenient, efficient, easily portable and safe for the user, particularly when used for maintaining deployment shelters in a fixed position in a variety of environmental conditions.
In one embodiment of the present disclosure, a system for use with a shelter includes a collapsible anchor, a plurality of parallel engagement apertures, a closure band and a side aperture. Typically, the collapsible anchor has a pair of opposing walls and a pair of opposing sidewalls. The opposing walls and the opposing sidewalls may define a top opening with an anchor cavity. The plurality of parallel engagement apertures may be spaced along an upper portion of the opposing walls. The closure band may be strung between two of the engagement apertures, for instance the closure band may cinch the top opening. The side aperture on a distal end of an upper portion of the sidewall may be adapted to a secure a leader to the anchor.
In some examples, the collapsible anchor includes an inner liner. The collapsible anchor may be a semi-rigid frame. For instance, the semi-rigid frame may be adapted to retain a substance chosen from water and sand. The plurality of engagement apertures may be spaced evenly along the top opening Each of the anchor sidewalls may include a wide lower portion and a narrow upper portion. Typically, the shelter is portable.
In another embodiment of the disclosure, an anchor for securing a shelter to a surface includes a base, a first and second collapsible wall, a third and fourth collapsible sidewall, and at least one inner sidewall. Typically, the base contours flatly on a surface. The first and second collapsible wall may extend upwardly away from the base. Each the sidewall may include a wider lower portion and a narrow upper portion. The at least one inner sidewall may be secured between the first and second collapsible walls, and in some cases partially separate the anchor into at least two compartments. The first and second walls may oppose one another and the third and fourth sidewalls may oppose one another. Further, the first and second walls may be substantially perpendicular to the third and fourth sidewalls.
In some examples, a surface area of an upper face of the anchor is smaller than a surface area of a footprint of the base. The first and second walls and the third and fourth sidewalls may define a semi-rigid frame. The frame may include an enforcement strip. The collapsible walls may include a plurality of parallel engagement apertures. A closure band may be strung between parallel engagement apertures. At least one of the collapsible sidewalls may include a side aperture secures a leader. The inner sidewall may include a flange securing the inner sidewall to the wall.

DESCRIPTION OF EMBODIMENTS
In the following description, like reference characters designate like or corresponding parts throughout the several views. Also in the following description, it is to be understood that such terms as “forward,” “rearward,” “left,” “right,” “upwardly,” “downwardly,” and the like are words of convenience and are not to be construed as limiting terms.
Referring now to the drawings in general and FIGS. 1 and 2 in particular, it will be understood that the illustrations are for the purpose of describing embodiments of the disclosure and are not intended to limit the disclosure or any invention thereto. As best seen in FIG. 1, a shelter 100 and anchor 10 are shown embodied according to the present disclosure. Anchor 10 may include a pair of opposing collapsible walls 12 and a pair of opposing sidewalls 14 with a top opening 18. The anchor 10 may include a plurality of engagement apertures 30 to cinch closed the top opening 18 and side apertures 32 to secure guy leaders 102 between the shelter 100.
As shown in FIG. 1, anchor 10 is generally configured to receive and retain materials, such as water, sand, rock, dirt, bricks and the like, and is typically aligned adjacent to any of the shelters shown and described herein. Anchor 10 includes a base 20, which may include any variety of base linings, inner frames and the like to generally mate with any contour of surface 200. Base 20 may be reinforced for durability to endure dragging and contact with rough surfaces. Further, the sidewall 14 may include a sidewall base 20a that traverses distally away from the base 20 to provide a greater footprint of support on the surface 200. The anchor includes at least a pair of opposing walls 12. As shown in FIGS. 1, 2 and 5, the first and second walls 12 may be constructed of collapsible materials for ease of storage, set-up and carry. Portability of the anchor allows any of the anchor embodiments and examples shown and described herein to be transported to remote and difficult to reach locations, for instance because the anchors are lightweight to carry and collapsible.
The sidewalls 14 are secured adjacent to the walls 12 in any manner, including one piece construction or support edges as shown in the various views. Unexpectedly, Applicants have discovered the onion-like shape defined by the sidewalls and walls creates a unique bladder for filling with unique stability features. As shown in FIG. 2, the sidewall 14 includes a wide lower portion 14a and a narrow upper portion 14b. The lower footprint surface area is thus larger than the upper surface area to provide structural integrity against environmental conditions, for example, severe weather and uneven ground, for instance by lowering the center of gravity of the anchor and expanding the base support to contour with the surface 200. In some examples, the anchor 10 may be constructed from heavy UV, mildew and fire-resistant vinyl and nylon. In other examples, bags filled with materials, such as rocks, dirt and water may be fitted and inserted into the anchor. The anchor 10 is configured for quicker and easier fill, while still being durable, lightweight and easily transportable. The anchor 10 is environmentally friendly as it allows minimal environmental impact in environmentally sensitive areas. Weighted unnatural substances need not be imported for fill and minimal disturbance to the environment is achieved. The anchor 10 is a no-impact anchor that stabilizes and secures shelters without the need for drilling and/or attaching to existing structures.
The perimeter of the upper anchor, i.e. the upper walls 12 and sidewalls 14, generally define the top opening 18 to expose the anchor's bladder. As discussed hereinafter, the anchor may include one bladder or a plurality of segmented, or partially separated, bladders. The bladder may be single lined or include multiple liners for secure handling of a variety of filling materials, which include, but are not limited to, water, rock, dirt and sand. The anchor's ability to hold a variety of filling materials allows the anchor to be carried collapsed and unfilled during a deployment and then to be filled with whatever materials are available on site. The filling materials may be emptied then on-site when leaving the deployment and the anchor collapsed for easy return carry. This allows deployed personnel to minimize the supplies needed and prevents having to carry, often excessively heavy, items for securing the tent or shelter. The upper perimeter may include an enforcement strip 34 and a variety of securement apertures. In some examples, the enforcement strip is reinforced fabric, plastic and the like to provide structural integrity around any of the securement apertures. Side strips 50 may be provided down the sidewalls 14 of the anchor.
Often, in rapid deployment situations, access to materials is limited and shelters may be quickly set-up in a variety of environments. Conventional types of anchors for shelters do not function as multi-use, for example, accommodating a variety of weighted substances such as sand and/or water and/or materials available at the deployment site. Further, conventional types of anchors for shelters do not function in a multitude of unexpected environments, such as, by way of example, shelters set-up on concrete or asphalt in one instance, unlevel ground, remote locations with limited access to either water and/or sand in other deployment instances. Applicant's anchor system accommodates a variety of weighted substances in a variety of deployment conditions.
The anchor includes engagement apertures 30 to generally secure the top opening in a closed position by cinching the opposing walls 12 together. As shown in FIGS. 2 and 3, parallel engagement apertures 30 may be spaced parallel and opposed from one another on the walls 12. Further, the anchor may include side apertures 32 to generally secure guy leaders, and the like, between the anchor 10 and shelter 100. In addition, guy leaders may be secured to fasteners of the engagement apertures as shown herein. Those of ordinary skill in the art having the benefit of this disclosure will recognize that any of the apertures described herein include a variety of sizes, shapes, styles and support backings to generally secure guy leaders, ropes, bands and the like between the anchor 10 and shelter 100. In some examples, the anchor system is a multi-point anchor system adapted so that the apertures may engage the shelter at multiple points. The multiple points may be at more than two corners of the shelter and/or locations between two corners of the shelter.
Anchor 10 includes a bladder to generally receive and retain any variety of filling materials. Certain examples of the anchor 10 includes an individual bladder, while other examples include segmented or partially-segmented bladders. Multiple bladders may be joined to create a double, triple and/or series of bladders. In one example, a bladder may form around a 20 to 40 gallon compartment. Smaller and larger bladder compartments are also within the scope of this invention. FIG. 4 shows one example of a partially segmented anchor having an inner sidewall 16 defining a first outer bladder and a second inner bladder 42. The inner sidewall 16 may have a height to generally segment bladder sections, while other examples include shorter heights or pass through ducts to allow fill material to flow between the bladder compartments. As shown and described herein, the inner sidewall 16 is generally secured between the opposing walls 12. The inner sidewall 16 may include a flange 44 affixed to the opposing walls 12. Further, the bladder may include a bladder liner 46 to generally protect the anchor from fill materials and handling. In some instances where the inner bladder is segmented into compartments, each bladder may be filled with varying materials.
As further shown in FIG. 4, a closure band 36 may be threaded through the opposing engagement apertures 30 and may cinch the top opening closed in an assembled position. In particular examples, the closure band is rigid, while other examples include a semi-elastic band. In addition, the segment 30a of the closure band 36 may be used to attach to a variety of guy leaders and the like, for instance through retainer 38. The retainer 38 may be carabineer, swivel or the like.
Any of the shelters 100 shown or described herein may include a variety of field deployment elements. For instance, the shelter may be light weight for easy carry transport and may include an articulated frame, robust coverings, canopy and canopy features, door openings, lighting features, power features, liners and additional water bladders, anchor weights, and sand bags. The shelters may be any size and multiple shelters may be joined through door openings to create scalable complexes with the advantages of the inventions herein. Particular shelter examples include, but are not limited thereto, a unit with floor space of about fifteen feet by twelve feet and an area of about one hundred and height square feet; a unit with floor space of fifteen feet by eighteen feet and an area of about two hundred and seventy feet; and a variety of other sizes.
In other embodiments, the disclosure includes a shelter kit. In this embodiment, the kit may comprise a shelter 100, e.g. any of the shelters previously shown or described, and a plurality of anchors 10, e.g. any of the anchors shown or described.
In yet another embodiment of the disclosure, included is a method for assembling a collapsed anchor 10 and securing the anchor 10 to a shelter. The method may include carrying the bag anchor 10 collapsed, separating and/or unfolding the walls 12, expanding the anchor 10, aligning the anchor 10 adjacent to a shelter and filling the anchor bladder with a fill materials, e.g. including any of the embodiments previously shown or described.
Numerous characteristics and advantages have been set forth in the foregoing description, together with details of structure and function. Many of the novel features are pointed out in the appended claims. The disclosure, however, is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts, within the principle of the disclosure, to the full extent indicated by the broad general meaning of the terms in which the general claims are expressed. It is further noted that, as used in this application, the singular forms “a,” “an,” and “the” include plural referents unless expressly and unequivocally limited to one referent.
