COMBINATION SWIMMING POOL. AND BOMB SHELTER Original Filed Sept. 21, 1960 5 Sheets-Sheet 5 SOR (50h INVENTORS JAMES R. TAYLOR ARTHUR J. BARKER Uite States Patent Cfiice hlldd id Patented Jan. 21, 1964 The present invention relates to a novel structure which can be utilized both as a swimming pool for an individual home, for example, and which could be readily converted for use as a bomb shelter. The present application is a continuation of an application Serial No. 57,- 540, filed September 21, 1960, and now abandoned.

The principal object of the present invention is the provision of a swimming pool structure which can normally be utilized for swimming but upon short notice may be converted to a suitable bomb shelter for occupancy during and after a bombing attack which may include radiation fall-out. The invention permits individual families to make an investment in a structure which can serve both as a swimming pool and a bomb shelter thereby encouraging the construction, use and maintenance of these faciL ities which would add to the health, enjoyment and security of the population.

in carrying out the invention, it is proposed to provide a more or less conventional swimming pool structure including a foldable cover normally maintained at one end or side of the pool which may be quickly and readily moved into place over the entire pool to convert the pool into a dwelling, providing shelter against radiation fallout as well as against weather.

The invention also contemplates provision of a swimming pool structure in which one or more Walls form a common wall of a bomb or fall-out shelter, and/ or storage bunkers in which food, clothing, medical supplies, fuel, etc, may be stored and to which access may be had from the interior of the pool in time of emergency.

A further object of the invention is the provision of a novel swimming pool structure of the type mentioned having a surge tank in the drain line for the swimming pool whereby a substantial amount of water in the pool can be quickly drained for rapid conversion of the interior of the pool to a shelter structure for persons during or after a bombing attack, the surge tank being connected to the usual draining system for gradually draining into the public sewage system.

Still another object of the invention is the provision of a pool structure having laterally extending portions at the bottom thereof to prevent raising of the pool by hydrostatic pressure in the soil in the event the pool has been drained.

in the form of the invention, the swimming pool struc ture is provided with a concrete compartment to one side of the pool and well beneath the upper level thereof and having entranceways thereto, preferably at the deep end of the pool structure, and in another form of the invention, a relatively shallow portion of the pool is provided, the bottom wall of which comprises the roof and end wall of a bomb or fall-out shelter and storage compartment located beneath the shallow portion of the pool, which compartment preferably has an entranceway at one side of the pool structure and which is partially or substantially entirely located beneath the water in the pool so that the water in the pool affords protection from overhead blasts and fall-out. Preferably, means are provided in the compartment for utilizing water in the pool for living Within the compartment.

Referring to the form of the invention shown in FIGS. 1 through 6, a swimming pool Pl is shown which may be located adjacent to a home and which may be used as a swimming pool by the occupants of the home or it can be converted, when necessary, to a bomb shelter in which the home occupants can survive during and following a bombing attack. In the form shown, the pool is constructed in an excavation in the earth and is of concrete suitably waterproofed in a conventional manner. Although the pool shown is beneath the ground level, it could be more or less above the ground with suitable supporting means thereabout.

The pool includes the usual sloping bottom having a shallow portion 2th: which is connected by a fairly steep slope 2% with a deep portion 20c. Preferably a stairway Ztld is formed at one side of the pool leading from portion 29a to portion 260 and suitable guard lines 202 are provided as shown. The pool includes a shallow end wall 21, two parallel side walls 22; and 23, and a deep end wall 24. The bottom structure of the pool includes laterally projecting ledges 2% preferably sloping upwardly on the undersides, for anchoring the pool against upwardly directed hydrostatic pressure therebeneath to prevent heaving of the pool when it is empty, the sloping undersides of the flanges facilitating the escape of water from beneath the pool structure.

The

sides

22 and 23 extend beyond wall 24 and coop erate with the lattter to form the ends and one side of a compartment 25 located in an excavation adjacent to the deep end of the pool, the details of which compartment are described more fully hereinafter.

On the outer side of wall 23 and well below the ground level is a rectangular bomb or fall-out shelter compartment 26 which is formed of concrete, and wall 23 forms one wall thereof and has

doorways

27 and 23 formed therethrough by which persons may enter and leave the compartment from the deep end of the pool. Preferably, hand operated blower mechanisms 30 are provided within the compartment and include vent pipes 39a leading above ground to suitable intake hoods 3% through which air may be brought into the compartment. These devices are conventional and the details thereof are not essential to the understanding of the invention. Additionally, compartment 26 may have a bench therein, or other minimal, waterproof furnishings.

Reverting to the construction and purpose of cornpartment 25', partitions are provided which form

separate bunkers

25a, 25b, and 250 for living supplies, fuel oil and

water tanks

32 and 33, for example, and food, tools, medical supplies, clothing, etc.

Tanks

32 and 33 have valved discharge pipes 32:: and 33a attached thereto which extend through openings in wall 24 by which water and oil can be drawn from the respective tanks by persons in the deep end of the pool, as required.

Bunker 250, which is relatively large as shown, is utilized for the storage of food, medicines, clothing, etc. as indicated generally at 35, wall 2-4 having an opening or doorway normally closed by a tapered removable waterproof door 36 through which access may be had to bunker 25c. Preferably, a ladder 37 is attached to wall 24 to provide means for swimmers to climb from the deep end of the pool, or in the event the pool is used as a shelter to afford means of access to door 36 when 'it is necessary to gain access to materials in the bunker.

Preferably, the top of compartment 25 is closed by a plate 39 which rests thereon. in the form of the invention shown, a diving board 443 is attached to the pool structure and it projects over plate 39 and into the pool, as seen in FIG. 1.

The deep portion 2dr: of the pool includes a dry well 42 from which water is pumped by a hand pump stowed in bunker 25c and which well may serve as a toilet when the pool is used as a shelter, suitable sanitizing chemicals being provided in chamber 25 for use in the toilet. The pool is emptied through a drain pipe 43 which discharges into a surge tank 44 located principally beneath the level of the bottom of pool 29c and which is connected by a pipe 4-5 including trap 45a to the public drainage sewer .system. Preferably, the pool is provided with an overflow pipe 4-6 at the deep end which discharges into tank 44 and which maintains a normal level of water in the pool, as seen in FIG. 6, which is usual practice in swimming pools. Pipe 4-3 is controlled by a valve 43a which is actuated by a hand wheel 43b locatedabove the ground surface.

The capacity of the surge tank 44 is such that when valve 43a is opened, a substantial portion of the water in the pool flows intotank 44 within a relatively short time whereby should an emergency arise for using the pool as a bomb shelter, the water can be rapidly discharged from the pool to make it usable as a bomb shelter by reason of surge tank 44 which retains a portion of the water in the event the public sewage system is overloaded from other pool drainage.

In the form of the invention. shown, the pool is filled with water through a supply pipe 4-? which is controlled by a hand operated valve d8. It is to be understood that the usual chlorinating and purif ing or filter system is desirably utilized with the pool, but since such systems are well known, they are not shown here.

The top of the pool is adapted to be quickly closed by a foldable cover indicated generally at 5% and which cover comprises a plurality of panels Eda, 5%, sec, Edd, Stle and 59 hinged to one another as described more fully hereinafter so that they may be folded and normally retained in compact form over cover plate 39. These cover panels are preferably each formed of an upper and lower sheet, the upper sheet having a transversely downwardly extending ridge Silg'along one edge which engages with the lower sheet, and the lower sheet having an upwardly extending trans-verse ridge 58h at the opposite edge engaging the upper sheet and which ridges space the sheets so as to accommodate hydrogen rich radiation shielding material 51, such as polyethylene, to minimize penetration of dangerous dosages of radia- 4 tion through the panels. The adjoining panels are connected with one another by hinge means, the alternate of which hinge means has rollers 6% which ride in tracks or grooves 22:: and 23a formed longitudinally in the tops of the

pool side walls

22 and 23, respectively. The rollers 69 include axles 61 which are journaled in hinge brackets 62 attached to the bottom plates of the cover panels to permit the adjoining edges of the panels to swing upwardly, as clearly seen in FIG. 13. The other hinge means comprises hinge plates 64 and pins 65 journaled therein so that the edges of the panels joined by these hinges may swing downwardly about the hinge.

The space between panels Stlb and Ella, and Slld and 5 3a are closed by a flapper plate 66 pivoted at 66a to an inset in the panel so that the plate extends over the adjoining panel when the cover is in its closed position as shown in FIG. 4, for example, and which raises to a vertical position when the cover is folded back, as shown in FIG. 1. The hinges between plates Stla and 5-21), and Ella and 56d are covered by transverse extensions of the top plates along one edge. Preferably, transverse grooves Silk are formed in the panels to drain off water which may seep around the cover plates.

Preferably, a flexible material, such as plastic 67 is attached to overhanging side edges of the panels and falls into place alongside the pool wall, as shown in FIG. 14, to prevent entrance of rain, snow and wind into the shelter formed by the pool structure.

It will be seen that by the construction shown, the nonwheeled hinges 64, 65 can be raised as the cover is moved toward the right hand end of the pool structure as shown in FIG. 1, so that the cover folds accordion-fashion over plate 39 as it is rolled on the rollers 69.

Another form of the invention is shown in FIGS. 7 through 11 and it comprises a pool formed in an excavation in the earth and includes a bottom which has a gradually sloping shallow section 1439a, an intermediate sharply sloping section Ittlllb and a relatively flat deep section idtlc. The pool includes side walls 101, m2 and end walls 193 and 104 all of which are formed of waterproofed concrete in a conventional manner.

A shelter chamber N5 is formed beneath wall sections ltlda and 1%?) which form the ceiling and one end wall of this shelter. The bottom of the shelter is formed by an extension lllild of bottom ltlllc, and preferably, the shelter includes a rectangular concrete section fillSa which is enclosed on all but one side which is open to the section immediately beneath wall ltltla. Access is had to shelter 1% through entrance 1% formed at one side of the pool, which opens into a vestibule of a stairway it")? constructed in a well 198 descending along the side of the pool. The stairwell has an entrance 3.69 which may have a railing around three sides thereof, as shown in FIG. 7.

Compartment ltrs 'a may have suitable seating or sleeping accommodations, and suitable hand operated ventilating air pumps or blowers 3d are provided.

in order to provide water from the pool for the occupants of shelter 95, a pipe and spigot ill is imbedded in wall 36%; and has one end o ening 'ato the lower part of pool lt t c.

A cover 112, likecover 55 is provided which is nor mally folded over a platform ll?) formed at one end of the pool and to which a board 114 may be attached.

Pool 1% may be drained and filled by operation of hand valves 116 and 117 in the normal fashion and the pool may be equipped with the conventional chlorinating and filtrating system, but which are not shown.

in the form of the invention just described, it is desirable to maintain the water in the pool during its use as a bomb shelter, although cover 112 may be closed, as shown in FIGS. 7 and 8, to protect the water from excessive radiation. It will be seen that the water in the pool alfords elfective protection against etlects of radiation and also cushions blast shocks of bombs. Furthermore, water from the pool can be utilized for living and is readily available to pipe 111 as desired, provided, however, it does not contain excessive radioactive materials.

It will be seen that by our invention we have provided a swimming pool structure which may serve as an effective bomb shelter and which costs but slightly more than a standard swimming pool. The fact that the structure has a dual purpose, one of which is highly desirable to most families and the other of which would ordinarily e deemed to be a doubtful investment of capital although of great importance in the event of a bomb attack, should encourage persons to make the investment therefor which will be highly desirable in either phase of its use.

While we have described but two forms of the invention, it is apparent that the two embodiment of the invention show the concept of combining a bomb shelter with a swimming pool in a unique manner such that one common structure is achieved having a cover over the pool of such construction that radioactive contamination of the water in the pool is prevented and wherein in the one embodiment the water in the swimming poolserves to protect the occupants of the bomb shelter at any time of the year as needed from the harmful effects of radiation from above, however it will be obvious to those skilled in the art that numerous modifications, alterations and deviations may be made without departing from the spirit or scope of the invention as defined by the following claims.
