Preferably the anchor rings 326 are attached on the perimeter of thecover 100. More preferably the anchor rings 326 are attached on the exterior of thelip 102. - In the embodiment of
FIG. 4 , theanchor 320 is shown attached to thecover 100 by a plurality ofsteel rods 328. One end of thesteel rod 328 is attached to thecover 100 at theanchor ring 326. Preferably thesteel rod 328 is secured to theanchor ring 326 by abolt assembly 330. Thesteel rod 328 is attached at the opposite end to theanchor 320 at theanchor ring 324. Preferably thesteel rods 328 are secured to the anchor rings 324 on theanchor 320 by a nut andbolt assembly 330. - Preferably the
anchor 320 is constructed of steel. More preferably theanchor 320 is constructed of steel plate. This embodiment of theanchor 320 may be achieved by utilizing the steel remaining from formation of thecover 100. - Looking again to
FIG. 1 , thestorm shelter 10 is shown with aladder 400 affixed to thecover 100. Theladder 400 is used as the means of ingress and egress to thestorm shelter 10. Preferably theladder 400 has four steps. Preferably theladder 400 is installed so that it is suspended downward into the interior of thebase 20. More preferably theladder 400 is suspended at an angle. This installation is preferred as it provides for easier ingress and egress to theshelter 10. Alternatively the steps are constructed to reduce the likelihood of slipping. - Preferably the
ladder 400 is affixed to thecover 100. Theladder 400 is preferably rigid in construction. Theladder 400 is affixed to thecover 100 by a nut and bolt assembly 402. Theladder 400 may havechains 404 attached near amidpoint 403 of the ladder. Preferably thechains 404 are shorter in length than theladder 400. This will allow theladder 400 to be suspended from thecover 100 at an angle less than 90° relative to the cover. Thechains 404 are attached to thecover 100 by ahook assembly 406. The use of ahook assembly 406 will allow for the angle of theladder 400 relative to thecover 100 to be adjusted as needed. - With reference still to
FIG. 1 a ventilation system 500 is shown. The purpose of theventilation system 500 is to allow for fresh air to reach the occupants. In addition, theventilation system 500 is installed in a manner that limits the likelihood of any debris, dust, or water entering during a storm. - Preferably the
ventilation system 500 may be achieved through the use of a coveredroof louver 502. A coveredroof louver 502 is preferred as it minimizes the amount of debris that may enter theshelter 10. Preferably theroof louver 502 is made of steel. More preferably theroof louver 502 is made of steel plate. Preferably theroof louver 502 is welded around a perimeter of a hole cut in thecover 100. This will ensure that theroof louver 502 is stable under stress and eliminate any leakage from the area where the roof louver is attached to thecover 100. Alternatively theroof louver 502 may be attached by a bonding agent. One skilled in the art will recognize theroof louver 502 may be constructed from other materials including plastic or aluminum. - Alternatively the
ventilation system 500 can be achieved by means of a 180°elbow pipe 520 as shown inFIG. 4 . Thepipe 520 is installed through thecover 100 so a first opening of the pipe is located outside of thestorm shelter 10 and faces toward the cover and a second opening of the pipe opens into the interior of the storm shelter. The exterior opening of thepipe 520 preferably includes a screen, not shown, to limit the entry of debris or animals. Preferably thepipe 520 is made of steel. Alternatively thepipe 520 may be made of a rigid plastic material such as PVC. Other alternative embodiments of theventilation system 500 are contemplated such as installing a 180° elbow pipe so that it exits from the side of thestorm shelter 10 through thebase 20 and extends above ground. - Referring again to
FIG. 1 , it is seen how thestorm shelter 10 withintegrated seating 24 would appear after installation and with the preferred embodiments of adoor 200,anchor system 300,ladder 400, andventilation system 500. The majority of the components are prefabricated and fitted to the size requirements of thestorm shelter 10 so that additional work at the installation site is unnecessary. - To achieve the final form as depicted in
FIG. 1 , the installer is first required to excavate a hole in the ground of suitable width to accommodate thebase 20. The hole must also be of suitable depth so that when thestorm shelter 10 is installed only thecover 100 is above ground. Once the excavation is completed thebase 20 is positioned in the ground so that it will be level. - Next the
cover 100 is installed. Preferably thecover 100 comes from the factory with thedoor 200 attached to minimize installation time. First the adhesive 108 or other securing means is applied to theinterior lip 102. Thecover 100 is then lowered onto the base 20 so thelip 102 is securely fastened to the base by the adhesive 108 and a water tight seal is formed. - Once this step is completed, the
anchor system 300 is installed. Theanchors 302 are imbedded into the ground around the perimeter of thebase 20. Next thesteel bands 304 are secured to the four anchors 302. Once secured to theanchors 302 thesteel bands 304 are secured to the anchor rings 308. Thesteel bands 304 are attached by means of thebolt assembly 310. Thesteel bands 304 are secured to thecover 20 so that they have very little slack once installed. - After the
anchor system 300 is secure, the excavated area surrounding thebase 20 is filled with dirt from the original excavation. This dirt is compacted into the area around thebase 20. This is done until the fill dirt is level with thecover 100. Once complete theladder 400 may be installed by attaching it to thecover 100. After theladder 400 is secured at one end by the nut and bolt assembly 402 to thecover 100 thechains 404 are attached to themidpoint 403 of the ladder.
