Description
- This application claims priority to U.S. Provisional Patent Application No. 61/497,139, filed Jun. 15, 2011, which is incorporated herein by reference in its entirety.
- The present invention relates generally to portable shelters for use in severe weather conditions.
- Almost everyday in some place of the country, news of severe weather striking a town or residential development is published. Often, non-permanent housing structures, for example mobile homes, are severely damaged and individuals are injured when tornados, hurricanes or other forms of severe weather hit. Equally in more permanent housing structures, structures without an underground basement or cellar leave few areas to take cover and remain protected from severe weather events.
- There is a need for a portable severe weather shelter that is easily and securely installed with respect to mobile home structures and other housing structures without a basement to afford protection during severe weather events.
- An inventive severe weather shelter is disclosed for use by humans to quickly and easily take cover during a severe weather event. In one example, the shelter is retrofitted to an existing housing structure, for example a mobile home or a house with a crawl space which is easily accessible from inside the housing structure. The shelter is secured to the ground between the interior floor of the housing structure and typically a concrete slab or other rigid secure ground surface. The shelter includes a connector having a release portion which provides dual functions of expanding or contracting to ease installation, but also serves as a tear-away safety or release function to sever the shelter's connection to the housing structure. In the event of a severe weather event, one or more occupants of the housing structure can enter and position themselves inside the shelter from inside the housing structure or residence. In the event that the housing structure is separated from its foundation or moorings, the release portion severs to disconnect the shelter from the structure leaving the shelter safely secured in its original installation position on the ground surface.
- In one aspect, a portable severe weather shelter for use in connecting to an existing housing structure supported by a ground surface comprises a shell, a connector and an anchor. The shell defines an interior cavity and an entrance opening in communication with the cavity, the cavity sized and oriented to temporarily accept at least one adult substantially surrounded by the shell. The connector has a release portion and is adapted to connect the shell to the housing structure wherein the release portion is configured to tear under a severe weather event to separate the shell from the housing structure. The anchor device adapted to removably secure the shell to the ground surface.
- In another aspect, method of using a portable severe weather shelter with a housing structure comprising the steps of: positioning a severe weather shelter shell defining an interior cavity and having an entrance opening in communication with the cavity in proximity with a housing structure having an shelter entrance opening; aligning the housing structure shelter entrance opening with the shell entrance opening; and communicatively coupling the housing structure to the cavity by connecting a connector defining a tunnel between the housing structure shelter entrance opening and the shell entrance opening, the connector having a release portion capable of tearing away under severe weather conditions to disconnect the shell from the housing structure.
- These and other aspects will be described in additional detail below.
- The description herein makes reference to the accompanying drawings wherein like reference numerals refer to like parts throughout the several views, and wherein:
-
FIG. 1 is an exploded view of one example of the inventive shelter showing a connector with release and a sleeve; -
FIG. 2 is a side elevational view of the example of the inventive shelter shown inFIG. 1 connected to a housing structure; -
FIG. 3 is an exploded view showing one example of a shroud for circumscribing the example of the inventive shelter shown inFIG. 1 ; and -
FIG. 4 is a perspective view showing the example of the shroud disposed the example of the inventive shelter shown inFIG. 1 . - Referring to
FIGS. 1-3 , an example of an apparatus and method of use for a portable severe weather shelter is illustrated. As further described below, the shelter is of particularly useful when used with existing mobile homes as well as more permanent housing structures without a basement or cellar. The invention has other advantageous uses and applications known by those skilled in the art. - Referring to
FIGS. 1 and 2 , an example of asevere weather shelter 10 having abase 30 is shown in use with anexemplary connector 36 and asleeve 40 attaching the shelter to thefloor 18 of ahousing structure 16. In the preferred example,base 30 includes ashell enclosure 50 havinghead 54,body 56 andtoe box 58 portions defining aninterior cavity 60 as best seen inFIG. 1 . As shown,shell 50 is generally shaped in proportion to a human adult torso and suitable for short periods of time while a severe weather event, for example a severe thunderstorm, tornado warning, hurricane or other event blows over. Although different sizes and shapes may be used,shell 50 andinterior cavity 60 are sized to fit at least one full size adult in a generally lying down position with the head and shoulders toward thehead portion 54 and feet toward thetoe box 58. In alternate examples, shell andcavity 60 could be sized to fit two adults. In other larger examples, more than two adults could be positioned inshelter 10. - As best seen in
FIG. 1 , in the example shown,shell head 54 includes ariser flange 64 generally extending vertically from theshell head 54. Theriser flange 64 is annular and has aperiphery 66 defining a shell entrance opening 70 in communication withinterior cavity 60. For reasons explained below, in the preferred example shown, theperiphery 66 is square having dimensions of approximately 30 inches wide by 30 inches across. In one example,shell 50 further includes adoor 72 that closes off or substantially closes entrance opening 70 to prevent water or other flying debris to entercavity 60. When the shelter is not in use,door 70 may be used to keep out dust, insects and other objects from enteringshell 50. - In the example,
shell 50 further includes abottom surface 74 having a generally planar portion in theshell body 56 and a curved or radiusedportion 80 transitioning upward towardflange 64 as generally shown. On the opposite end towardtoe box 58,bottom surface 74 includes anangled portion 84. Opposite the bottom surface,shell 50 includes anupper surface 90 in the shell body area, arise 96 and a toe boxupper panel 100 leading to anend 104 connecting toangled portion 84. In a preferred example,shell 50 forms an uninterrupted, water and air tight enclosure with the exception ofentrance opening 70. In alternate examples, there may be perforations (not shown) through the shell into thecavity 60 for ventilation. These perforations may include screens or other barriers to keep insects and larger debris out of the interior cavity. -
Door 72 may include a water tight or other seal to close off entrance opening 70 to further protect against the elements. Alternate door examples may include a strong and rigid or flexible mesh or grid preserving ventilation while keeping large debris from enteringcavity 60. Other door and shell shapes and orientations known by those skilled in the art may be used. It is contemplated thatdoor 70 may be connected toflange 64 with a hinge or other mechanical fasteners or connectors which provide a secure connection while being quickly and easily operated in the event of an emergency such as a tornado that strikes with little warning. - In a preferred example,
shell 50 is made from a polymer material that is strong, impact resistant and lightweight allowing an average person to lift and manipulateshell 50 providing for installation to ahousing structure 16 by one person. Suitable polymers may include polyethylene, polypropylene and other polymers known by those skilled in the art. Reinforced composite materials such as fiberglass, carbon fiber, elastomers, thin gauge ferrous and non-ferrous metals and other materials may also be used. In a preferred example,shell 50 is a polymer that is molded or sprayed forming a one-piece, continuous, unitary shell as described above.Shell 50 may in alternate examples be made from multiple pieces secured together by mechanical or other means suitable for the base material used. - In the example illustrated,
shell 50 is used with anexemplary connector 36. In the example,connector 36 includes anupper skirt 110 having aperimeter 112, alower skirt 116 having a perimeter 118 and ashelter release portion 120 positioned between and connected to each skirt. Therespective perimeters 112 and 118 form a throughtunnel 114. When installed as illustrated and generally described below,tunnel 114 is in communication with shellinternal cavity 60 allowing a person to quickly pass throughtunnel 114 and intocavity 60. - In the example, connector upper 110 and lower 116 skirts are fairly rigid and may be made from the same or similar materials as
shell 50 noted above.Lower skirt 116 is sized for alignment with and connection to theriser flange 64 such thattunnel 114 is communicatively coupled with shellinternal cavity 60. As best seen in the example inFIG. 2 , lower skirt perimeter 118 is sized to slightly fit over the outside ofshell head periphery 66 and secured with mechanical fasteners (not shown). A seal (not shown) may be used to close any gaps to keep moisture, debris and insects from entering thetunnel 114 orshell cavity 60. - In the
example connector 36, therelease portion 120 is a flexible, accordion-style bellows 126 type device allowing the release portion to relatively easily expand and contract thereby increasing or decreasing the length ofconnector 36 to accommodate the specific application where theshelter 10 is to be installed. The release portion would further allow some flexibility and adjustment in a transverse direction for misalignment of the respective openings. In the example, bellows 126 is made from a light to medium weight textile fabric or mesh that is coated with a polymer or weather resistant coating (not shown) to keep out moisture and the elements from enteringtunnel 114 andshell cavity 60. As explained below, therelease portion 120 is designed to be capable of tearing under substantial force to allow separation of theupper skirt 110 connected to the housing structure and thelower skirt 116 connected to theshell 50. One example of a suitable material is marketed under the tradename Duro-Dyne. Other materials and constructions having the noted characteristics known by those skilled in the art may be used. - In the example shown in
FIG. 2 ,shelter 10 includes anexemplary sleeve 40 which is used to attach theconnector 36 andbase 30 to ahousing structure 16, typically afloor structure 18. In the example, a typical application forshelter 10 is mobile home having afloor 16 and an exterior surface orskin 22 separated byfloor joists 24 as generally illustrated. The exemplary sleeve for includes aflange 140 defining anupper surface 144 defining a throughopening 150 to be positioned in communication withtunnel 114 andinterior cavity 60. - In a typical but not exclusive application, where occupants of a mobile home desire to have a severe whether
shelter 10, a skilled carpenter or tradesman would cut a through opening orentrance 166 in thefloor 16 and theouter skin 22 in a location where convenient to quickly access and entershelter 10 when severe weather strikes. With a preferred 30 inch by 30 inch opening, removal of a portion of one stud typically positioned on 16 inch centers would be required along with the removal of any insulation. In such an exemplary installation,sleeve 40 is easily positioned under opening 150 with anupper surface 144 in abutting contact with the underside of thefloor 18 and between the remaining adjacent floor joists and with alower portion 146 extending below the floor joists.Sleeve 40 is then secured to thejoists 24 using mechanical fasteners (not shown). Depending on the application and surround housing structure, brackets, connectors, seals and other common securing and sealing devices (all not shown) may be used to provide a secure connection betweensleeve 40 and thehousing structure floor 18 thereby environmentally sealing thesleeve 40 to the housing structure. -
Exemplary sleeve 40 is generally shown as a square ring. Other polygonal and circular shapes, configurations and constructions known by those skilled in the field may be used.Sleeve 40 may be made from the same materials asshell 50, with light gauge sheet steel or aluminum being preferred. Other placements, orientations and methods of securingsleeve 40 tohousing structure 16 known by those skilled in the art may be used. - In the example described above wherein an
access opening 150 is cut into an existingmobile home floor 18, asturdy access door 170 may be installed providing a continuous floor surface and easy actuation to access theshelter 10 in the case of severe weather. Other access schemes known by those skilled in the art may be used. - In the example described and illustrated, it has been shown that the general configuration for
shell 50 being approximately 72 inches in length, slightly below 30 inches wide and 24 inches in total height, and having the head, 54,body 56 andtoe box 58 portions shaped and angularly oriented as generally illustrated, the 30 inch by 30 inch opening in thefloor 18 is sufficient to manipulate and orientshell 50 through the floor opening 166 to position the shell in the space between the housing structureouter skin 22 and theground surface 20 as generally shown inFIG. 2 . The method steps for connecting theshell 50 to thehousing structure 16 are conducted sequentially as generally described above. Other orders for the steps, for example, connecting thesleeve 40 first and then theconnector 36 last may also be used. - Referring to the example in
FIGS. 1 and 2 , ananchor device 180 is used to rigidly secure theshelter shell 50 to aground surface 20, preferably an existing cement slab or pad often used under existing homes and mobile homes as a foundation. In the example,anchor 180 includes twoindependent straps 186 which are positioned around selected portions of the outside ofshell 50 and extend toward theground surface 20. Mountingplates 190 are formed in thestraps 186 or connected thereto to provide a mounting surface generally parallel to theground surface 20. One ormore anchor bolts 196 is used for each mountingplate 190 to rigidly secure the strap around the shell and to theground surface 20. Where the ground surface is concrete, heavy duty anchor bolts are secured in pilot holes (not shown) drilled into the concrete. Suitable examples ofanchor bolts 196 are manufactured under the brand name Hilti. Other fasteners, such as lag bolts with lead anchors, as well as other fasteners known by those skilled in the art may be used. Where no concrete slab is available, other fastening methods and devices suitable for the particular application known by those skilled in the art may be used. Although described an illustrated as twostraps 186, more or less straps may be used as well as other anchoring devices and methods known by those skilled in the art. For example structural members (not shown) and mounting plates (not shown) could be integrally manufactured or molded intoshell 50 negating the need forstraps 186. - As noted, the
shelter 10 andshell 50 are designed of strong lightweight materials and is configured and constructed to be easily transported and installed by an average person in an existing housing structure with minimal effort. Further, theshelter 10 can be removed and relocated to another housing structure should the owner move or it is desirous to transport theshelter 10 to a different location. - In operation, on the onset of severe weather, at least one resident can seek shelter in
shelter 10 throughdoor 170. The individual would pass throughentrance 166,tunnel 114 and entershell cavity 60 throughentrance opening 70. The individual would then manipulate him/herself to a generally lying down position incavity 60. Optionally,shell door 72 would be positioned and/or closed to at least prevent large debris from entering the shell. - In the event that severe weather, for example a tornado strikes, and the
housing structure 16 is dislodged from its moorings, rolled over or blown away,connector release portion 20, being made from a flexible textile material, would tear away allowing thesleeve 40 and upper portion of thebellows 126 to travel with the dislodged housing structure leaving theshell 50 and occupant(s) safe and secure in theshell 50 rigidly connected to theground surface 20 as generally described above. Other release mechanisms allowing emergency detachment ofshell 50 from thehousing structure 16 known by those skilled in the art may be used. - In the event that the owner changes residences or the
shelter 10 needs to be removed, the described and illustrated construction and features render theshelter 10 easily removed and transported for installation at a new location in a similar manner as described. - Additional features can be included to supplement the protection afforded by the
