BACKGROUND OF THE INVENTION

The present disclosure relates to storm shelters and other survival habitats. More particularly, the invention disclosed herein relates to modular storm shelters and methods of installing and anchoring them to a substrate, such as the ground and/or a concrete slab and/or a bracket embedded in the ground.

SUMMARY OF THE INVENTION

One object of the present invention is to provide a shelter/container which is stable and immobile when an external force is applied thereon.
The present invention provides a shelter/container including a container body and a connection structure for affixing the container body onto an immovable object. Optionally, the connection structure affixes the container body onto the immovable object via a bracket, wherein the bracket is affixed to the immovable object. More specifically, the connection structure may be adapted for connecting with the bracket by way of threaded connection or buckled connection. More particularly, the connection structure may include a first wing-plate and an adjoining second wing-plate, the first wing-plate being adapted for attachment to the container body, and the second wing-plate being adapted for anchoring to the bracket.
Optionally, the container body may include a mounting block, and with the first wing-plate of the connection structure being adapted for attachment to the mounting block rather than directly to the container body. More particularly, the first wing-plate and the second wing-plate may be essentially adjoining perpendicular plates.
The connection structure may include a connecting rod moveably yoked to the container body, so that it can be moved between a first position and a second position. In one embodiment, when in the first position, the connecting rod is accepted within a connecting-rod sleeve on the bracket so as to prevent lateral displacement of the container body from the immovable object to which the bracket is anchored. And for the second position, the connecting rod is withdrawn from the connecting-rod sleeve to remove such connection. The connection structure may further include a position-limit mechanism for keeping the connecting rod at the first position or the second position. The connection structure may alternatively include a block extending outwardly from the container body; the block may include one or more mounting holes thereon, each accepting a threaded element so as to engage with a connecting-rod sleeve on the bracket.
Optionally, the bracket may be adapted for anchoring containers having different sized “footprints”.
The connection structure may include a plurality of connection structures or sub-structures. Those may be periodically spaced or arranged on the container body.
The container may further include a reinforcement structure. For example, the reinforcement structure may include a plurality of reinforcing ribs; moreover, at least one of the reinforcing ribs may be configured to bridge opposite or adjacent walls of the container body.
The container may further include a container-door retaining structure for maintaining the container door at a closed position. Optionally, the container-door retaining structure may include a locking pin and a locking groove or other passageway, the locking pin being adapted for inserting into the locking groove so as to lock closed the container door. Or the container-door retaining structure may further include a stopping block, standing against the locking pin when the locking pin is inserted into the locking groove.
In comparison with the prior art, the technology and solutions provided by the present invention provide a number of advantages. For example, the disclosed container includes a connection structure for anchoring the container body onto an immovable object (e.g., the ground, wall of a building or a construction such as a concrete slab); when an external force is applied to the container (such as during server weather like a tornado, typhoon or tsunami), the container remains in an anchored position, so that the potential hazard to persons or property can be prevented or minimized.
The immovable object to which the container is anchored may be the ground or an immovable object anchored thereon. Accordingly, since the container disclosed herein is able to be anchored onto the immovable object, the container has good stability when an external force is applied thereon.
Further, the container disclosed herein may include a reinforcement structure configured inside the container body. For example, neighboring walls of the container body may be bridged by one or more reinforcing ribs; or a wall of the container body may be formed with one or more reinforcing ribs which intersect or overlap with each other. Therefore, the force-resistance performance of the container can be enhanced. When an external object crashes into the container, the container body which has good force-resistance performance is not easy to deform. Even if a small degree of deformation occurs, it is too little to cause damage to person or property inside the container.
Further, the shelter provided by the container disclosed herein is configured with a container door having a container-door retaining structure. For example, one or more locking pins may be disposed where the container door is located, for enhancing the locking of the container door. In comparison with an existing container door which is locked only with a conventional lockset, the container door of the disclosed container is further locked by a container-door retaining structure, which is not easily opened by external force. Accordingly, the container disclosed herein provides enhanced safety and reliable shelter for person or property.

(j) rated StormPro361 door frame and hardware system, installed at both ends of the container.
Alternatively, the container body may be manufactured without starting with any pre-existing container. The aforementioned enhancement (and others) may then be incorporated into the original structural rather than added later.
Referring to FIG. 1 and FIG. 2, a container according to one embodiment of the disclosed shelter/container is illustrated. The container includes a container body 100 and a connection structure 200 for anchoring the container body 100 onto an immovable object. The connection structure 200 is adapted for affixing the container body 100 onto the immovable object by way of an anchor base such as a bracket 300, with or without an embedded concrete slab.
The container body 100 is formed by a plurality of walls 101, preferably four walls upstanding from a floor and connecting to a roof. The multiple walls 101 are combined together and reinforced through a frame structure 102, thus forming a reinforced container. The container body 100 has an enclosed interior volume, used for providing shelter for persons and/or property.
The connection structure 200 is affixed onto the container body 100 and is adapted for affixing the container body 100 onto the immovable object via the bracket 300. The immovable object herein refers to the ground, or an object that cannot move or be moved with respect to the ground, such as a wall, a floor of a building or a construction such as a concrete slab embedded in the ground.
The bracket 300 is affixed to the immovable object. As shown in FIG. 2, the bracket 300 is affixed to the immovable object through an anchor bolt or pin 301.
Accordingly, when the connection structure 200 (affixed on the container body 100) connects with the bracket 300 affixed on the immovable object, the container body 100 is anchored onto the immovable object. In this circumstance, the container can be maintained immobile even when a strong external force is applied thereon. Therefore, damage caused to person and property inside the container can be avoided.
In some embodiments, the connection structure 200 is affixed to the frame structure 102 of the container body 100. As shown in FIG. 1, the connection structure 200 is affixed to a bottom frame 1021 of the frame structure 102. It should be noted that, in this embodiment the connection structure 200 is affixed to the bottom frame 1021 of the frame structure 102, which is just for illustration and should not be taken as a limitation to the disclosed shelter/container. In some embodiments, the connection structure 200 may be affixed elsewhere on the frame structure 102. In some embodiments, the connection structure 200 may be affixed to any one of the walls 101 of the container body 100.
In some embodiments, the connection structure 200 may be two or more structures or sub-structures. The two or more connection structures 200 are arranged on the bottom frame 1021 of the container body 100. Further, the two or more structures 200 may be evenly spaced or unevenly spaced. The arrangement and spacing of connection structures may be dictated by the dimensions of the container body, the characteristics of the substratum, the amount of external force anticipated to be encountered, and the level of safety and security being planned for.
In combination with FIG. 3 and FIG. 4, in some embodiments, the connection structure 200 includes a winged connector including a first wing-plate 201 and a second wing-plate 202. The first wing-plate 201 and the second wing-plate 202 are joined. For example, the first wing-plate 201 and the second wing-plate 202 may be an integral structure. The first wing-plate 201 is adapted for connecting with the container body (e.g., the wall 101 or the frame structure 102 of the container body 100). The second wing-plate 202 is adapted for anchoring to the bracket 300.
In some embodiments, the first wing-plate 201 of the connection structure 200 is detachably connected to the container body 100. Specifically, the first wing-plate 201 is detachedly affixed onto the container body 100 via a threaded element 401. The threaded element 401 may be a bolt, a screw, a rivet or any other threaded connection. In addition, the first wing-plate 201 of the connection structure 200 may be detachably connected to the container body 100 by way of buckle connection or any other connection method.
In some embodiments, the frame structure 102 of the container body 100 may be a hollow structure, or the wall 101 of the container body 100 is too thin to provide sufficient structural support for anchoring the container body. In order to improve the strength and structural sufficiency of the connection between the first wing-plate 201 and the container body 100, in some embodiments, the container body 100 includes a mounting block 1031. The mounting block 1031 extends outwardly from the container body at a position corresponding to or aligned with the connection structure 200. The first wing-plate 201 of the connection structure 200 is connected to the mounting block 1031 on the container body 100, rather being directly connected to the container body 100, so as to improve the strength and structural sufficiency of the connection between the connection structure 200 and the container body 100.
In some embodiments, the first wing-plate 201 of the connection structure 200 is permanently connected to the container body 100. Specifically, the first wing-plate 201 may be connected to the container body by way of welding.
The second wing-plate 202 of the connection structure 200 is adapted for affixedly connecting with the bracket 200. Specifically, when the container is placed on the immovable object or at a position close to the immovable object, the second wing-plate 202 of the connection structure 200 is adapted for connecting with the bracket 300. By such way, the container body 100 is affixed on the bracket 300. As the bracket 300 is affixed onto the immovable object, the container body 100 is affixed on the immovable object.
In some embodiments, connection between the second wing-plate 202 and the bracket 300 is realized by a threaded element 402 and a connecting-rod sleeve 302 (as shown in FIG. 1) formed on the bracket 300. In some embodiments, the connection between the second wing-plate 202 and the bracket 300 may be realized by way of buckle connection.
In some embodiments, as shown in FIG. 3, the first wing-plate 201 and the second wing-plate 202 are perpendicular to each other. In some embodiments, the first wing-plate and the second wing-plate may be configured coplanar. When the first wing-plate and the second wing-plate are coplanar, it means that, a mounting surface of the first wing-plate and a mounting surface of the second wing-plate form an angle of 180 degree or are parallel with each other. The mounting surface of the first wing-plate refers to a surface of the first wing-plate in contact with the container body when being affixed on the container body. Similarly, the mounting surface of the second wing-plate refers to a surface of the second wing-plate in contact with the bracket when being affixed on the bracket.
In some embodiments, as shown in FIG. 3 and FIG. 4, the first wing-plate 201 and the second wing-plate 202 are disposed with a rib plate therebetween, for strengthening the connection between the first wing-plate 201 and the second wing-plate 202. As such, cracking or breaking at a portion between the first wing-plate 201 and the second wing-plate 202 due to stress concentration can be prevented.
In addition, the first wing-plate may be configured into a regular shape such as rectangle, arch and so on, or be configured into an irregular shape. The first wing-plate may be configured into a solid structure or a hollow structure with holes or grooves. Similarly, the second wing-plate may be configured into a regular shape such as rectangle, arch and so on, or an irregular shape, and be configured into a solid structure or a hollow structure with holes or grooves.
Referring to FIG. 5 and FIG. 6, a connection structure 200 a according to another embodiment of the disclosed shelter/container is illustrated. The connection structure 200 a includes a connecting rod 201 a, a holding structure 202 a (such as a support cylinder) and a position-limit mechanism 203 a (such as a stop or eyelet outstanding from the container body).
The holding structure 202 a is adapted for yoking the connecting rod 201 a on the container body 100, allowing it to move as needed while maintaining its necessary alignment with other structural elements. When being yoked to the container body 100 via the holding structure 202 a, the connecting rod 201 a is able to rotate around its own axis and move along its axis. Through such movement, the connecting rod 201 a can be moved between a first position and a second position. When the connecting rod 201 a is moved to the first position, as shown in FIG. 5, the connecting rod 201 a engages with the connecting-rod sleeve 302 (as shown in FIG. 1) formed on the bracket 300, so as to prevent lateral displacement of the container 100 on the bracket 300. When the connecting rod 201 a is switched to the second position, as shown in FIG. 6, the connecting rod 201 a withdraws from the connecting-rod sleeve 302 on the bracket 300, thus the container can be moved according to practical demand.
The position-limit mechanism 203 a is adapted for maintaining the connecting rod 201 a at the first position or at the second position.
Referring to FIG. 7, a connection structure 200 b according to another embodiment of the disclosed shelter/container is illustrated. The connection structure 200 b is a block extending outwardly from the container body 100, and includes a bore allowing a pin or threaded element to pass through the block to engage with the connecting-rod sleeve 302 (as shown in FIG. 1) on the bracket 300, thus connecting the connection structure 200 b with the bracket 300. Accordingly, the container body 100 is affixed on the bracket 300.
In addition, in some embodiments, as shown FIG. 8, the bracket 300 is formed with a plurality of the connecting-rod sleeves 302. The multiple connecting-rod sleeves 302 allow the bracket 300 to anchor different containers having different sized bases or “footprints”. In other words, containers having different base dimensions can be anchored onto the immovable object through one common bracket 300. For example, as shown in FIG. 8, the connecting-rod sleeves 302 within the dotted frame are able to connect with a connection structure of a container with a relative small size, while connecting-rod sleeves 302 outside the dotted frame are able to connect with a connection structure of a container with a relative large size. By such way, adaptability of the bracket 300 is improved.
In embodiments recited above, the container body is affixed onto the immovable object by: connecting the connection structure affixed on the container body with the bracket affixed on the immovable object. In other words, the connection structure affixes the container body onto the immovable object through the bracket. In some embodiments, the connection structure may affix the container body onto the immovable object by directly connecting with the immovable object. Specifically, the immovable object is formed with one or more connecting-rod sleeves thereon. The connecting-rod sleeve is adapted to connect with the threaded element 402 (as shown in FIG. 3), or the connecting rod 201 a (as shown in FIG. 5), or the threaded element 402 b (as shown in FIG. 7), so as to affix to the container body onto the immovable object directly.
Accordingly, the container of the disclosed shelter/container is configured with a connection structure thereon for affixing the container body onto an immovable object. As such, the container possesses good stability when an external force is applied thereon.
In order to improve safety and reliability of the container, in some embodiments, as shown in FIG. 9, the container further includes a reinforcement structure 500. The reinforcement structure 500 is disposed inside the container body 100, for improving stability of the container body 100 and enhancing force-resistance of the container body 100.
The reinforcement structure 500 includes one or more reinforcing ribs. Part of the plurality of reinforcing ribs may be configured bridging two neighboring walls 101 of the container body 100. Such as reinforcing ribs 501 as shown in FIG. 9, wherein the reinforcing ribs 501 bridge a top wall and a side wall of the container body 100. The reinforcing rib also can be configured bridging two neighboring side walls of the container body 100.
Part of the plurality of reinforcing ribs may be configured on a same wall. Such as reinforcing ribs 502 as shown in FIG. 9, wherein the reinforcing ribs 502 are arranged on a same wall of the container body 100 and are intersected with each other.
Accordingly, when an external object crashes against the container body 100, the reinforcement structures 500 inside the container body 100 are able to prevent deformation of the container body 100. In other words, the configuration of the reinforcement structure 500 is able to improve the force-resistance of the container body 100. As such, the container body 100 is not easy to deform when a strong external force is imposed thereon. Or, even if there may be a small degree of deformation, the deformation is too small to cause any damage to person or property in the container body 100.
It can be understood that, the container is usually configured with a container door 103 (as shown in FIG. 2) for allowing person or property accessing or leaving the interior volume of the container body 100. When property is placed inside the container body 100, the container door 103 is closed to safeguard the property inside the container body 100. Usually, the container door 103 is closed via a conventional lockset. However, the force the conventional lockset is capable of enduring is relatively small. When an external force is imposed on the container door 103, the lockset is easy to be damaged. As a result, the container door 103 may be opened, and thus may allow damage to person or property inside the container 100.
In order to solve problems as recited above, in some embodiments of the disclosed shelter/container, as shown in FIG. 10, the container further includes a container-door retaining structure 600 for maintaining the container door 103 closed. The container-door retaining structure 600 is inside the container body 100.
Referring to FIG. 10, the container-door retaining structure 600 includes a locking pin 601 and locking slot (not shown in FIG. 10). The locking pin 601 is rotatably engaged to the container door 103, and the locking slot is formed on the door frame 104. The locking pin 601 is adapted for inserting into the locking slot, so as to maintain the container door 103 closed.
The container-door retaining structure 600 further includes a stopping block 602. When the locking pin 601 is inserted into the locking slot, the stopping block 602 stands against the locking pin 601 for stopping movement of the locking pin 601 along a direction of departing from the locking slot, thus preventing the locking pin 601 from getting out of the locking slot.
In addition, the locking slot may be a hole formed on the door frame 104, or a groove formed on the door frame 104. The hole may be a through hole or a blind hole. The locking slot may be in a shape of square or circle. The shape of the locking slot should not be taken as a limitation to the disclosed shelter/container, as long as the locking slot can allow the locking pin 601 being inserted into, and when the locking pin 601 is inserted in the locking slot, the container door 103 is kept at the closed status.
In addition, the container door 103 may be configured with two or more of the container-door retaining structures 600, or just configured with one container-door retaining structure 600.
Accordingly, in the container of the disclosed shelter/container, when the locking pin 601 is inserted into the locking slot, the connection between the container door 103 and the door frame 104 does not just rely on a conventional lockset, but also on the one or more container-door retaining structures 600. As such, the closed status of the container door 103 is more stable and reliable. Specifically, the container-door retaining structure 600 can resist an external force applied on the container door 103 more effectively, thus preventing the container door 103 from being opened or departing from the door frame 104.
