Abstract
The Submersible Power Device called later the Device or SPD covers the surface of the swimming pool when in upper position but is completely immersed (close to the bottom) when in lower position. Its intention is to protect people (also animals and other objects) from accidentally falling into the swimming pool (upper position), and be a rescue device which can quickly bring a person from any water depth up to the surface of the pool if any dangerous situation arises. When in its lower position the device does not in any way restrain the readiness of the pool for its normal use. The device does not negatively affect safety of the pool.
Description
~D I 5 C L O ~ (J R E 211 6 9 3 3 SPECIF~CATION
(1) This invention relates to the submersible power device installed in the home or public pool which purpose is to protect against accidental falling into the pool when in the upper (surface) position but enabling the use of the pool and becomming the rescue device in emergency when in the lowest (bottom) position.
(1) This invention relates to the submersible power device installed in the home or public pool which purpose is to protect against accidental falling into the pool when in the upper (surface) position but enabling the use of the pool and becomming the rescue device in emergency when in the lowest (bottom) position.
(2) There have been generally two types of the pool cover so far:
a) Piece of canvass, plastic or laminate foil cut according to the shape of the pool. Spread manually over the water surface, and attached to the pool banks when the pool is not in use.
b) Canvass or foil rolled on pulley at one side of the pool, unrolled manually or mechanically over the water surface and then attached to the other three sides of the pool.
As a concequence:
1) Covers of the first category are very difficult to spread if the size of the pool is large or the weather is windy. In order to use the pool the cover has to be removed and then, after the next use, put back in place. The inconvenience of such operation often makes people to give it up completely and it sometimes leads to tragic consequences.
2) Covers of both categories islolate the pool completely from its primary use i.e. SWimming once they are installed and secured. In oder to use the pool again the covers have to be removed or rolled back and then, after the use, put back in place.

3) They are useless when removed from the pool.
(3) Inventive idea:
I have found out that all the three main disadvantages of the existing covers ( i.e. tedious installation, pool isolation from the user when installed, uselessness when removed) can be overcome by the device called The Pool Safety Submersible Power Device, or simply called later in the text The Device which can completely cover the surface of the unused pool but instead of being removed when the pool is about to be used simply submersed and brought to the position at the very bottom of the pool. In this position The Device not only releases the pool for its normal purpose, but additionally becomes a powerful rescuing instrument which by returning to the surface can bring the rescued person to the safety. Special, modular construction of the device allows for easy installation in pools of odd shapes, bottom profiles, and different sizes without any changes done on the pool design and structure. This device is then superior to the so far exlsting pool covers .
21169~3 (4) Description The Device consists of:
1. The Submersible Platform (SP) the frame of which is made of sturdy polymer (polyca-rbonate, l~min~te, fibrous composite, etc) and the area bounded by the frame is filled with the polymeric grate or the mesh (Fig. 1). Size of the eye will determine the speed of the platform in the water - with big eyes, the platform can be moved faster because the water resistance is lower.
The faster the platform travels to the surface of the pool the more a rescue element the Device carries. With the mesh platform the speed will be really slow but less objects will fall to the bottom of the pool. In this case it is more like an ordinary pool cover but much more convenient in use. The frame can be tailored to the shape of the pool. It does not matter then if the pool is of the square, oval or kidney shape (Fig.2).
2. A number of Platform Elevating Modules (PEM) which can move the platform up or down (Fig.3). Each module consists of: a) worm or cone gear, b) Vertical Bolt wit square thread on it (VB) c), Platform Leading Nut (PLN), d) Casing (CS) in which all the former elements are encased (bearings are used to secure the bolt and gears in the casing)(Details a,b,c,d in Fig 3). As the driving shaft (DS) rotates, the worm or cone gear passes the rotation to the Vertical Bolt. The Platform Leading Nut is limited in its horizontal moves by the walls of the Casing (cannot rotate) but is free to move vertically up or down depending on the speed and direction of the rotation of the Vertical Shaft. The frame of the Platform is attached to one side of the Platform Leading Nut so it follows its movements (Fig.4). The walls of the Casing can be lubricated with water resistant grease on inside to facilitate the vertical movement of the Platform Leading Nut.
3. System of Driving Shafts (Fig.5) which passes rotation from the central electric motor placed outside the pool for safety reasons to the gears in all PEM's. If the bottom of the pool is flat the Driving Shafts are straight and placed horizontally at the bottom.
Principle of operation (Fig.6) The electric motor (a) drives the Shafts (b) which rotate the Vertical Bolts of all Platform Elevating Modules (via cone or worm gears)(c). PEM's move the Platform Leading Nuts (d) vertically and they, in turn, move the Platform (e), which is attached to them by means of pivoting or sliding rivets. The speed and direction of moving Platform depends on the speed and direction of the rotation of the driving motor. If all the Platform Leading Nuts are at their upper positions the submersible platform is slightly above the surface of the water and is protecting the people, animals, and objects from falling into the pool.
If all the Leading Nuts are in the lowest position the Platform is at the bottom of the pool. In this location of the Platform a) the pool is ready for use (for swimming), b) in case of emergency (person drowning, etc.) by turning on the motor the Platform can be brought back to the surface along with the rescued person. The Device is then multipurpose. It protects, rescues, and can be quickly transformed from performing one function to another. No fastening, removing, folding, ullwl~pping, etc. is ever involved. Installation of the device is easy as only Platform Elevating Modules have to be attached to the wall of the pool (Detail "e" in Fig 3). The construction allows the electric engine moving the Driving Shafts to be installed outside of the pool, far from the water. The rotation of the engine is passed to the Driving Shaft by set of cone gears (Fig.~).
If the pool bottom is flat and square, the Platform is also flat and square and it might be attached to the Nuts of four Platform Elevating Modules (Fig.7) The Driving Shafts pass the same movement to all worm or cone gears (all gears have the same ratio) and the Platform is uniformly moved up and down from the very bottom to the top and vice versa. Even at the very 21169~3 bottom the Platform covers all the moving parts (driving shafts and gears) preventing from touching them. The number of Elevating Modules depends on the shape and the size of the pool.
The more complicated the shape or the bigger the pool the more PEM's are necessary.
In most of the pools the level of the bottom is far from being uniform. The most popular is that allowing gradual entry on the one side and abrupt (for jumping into the water) on the other.
The Fig 8. shows an example of a small, square pool with part of its bottom being flat and another part sloped. The Device can be constructed in the way which overcomes the problem of different bottom levels. In this situation the Platform consists of as many separate pieces as many levels the bottom has. Gear ratio of the Elevating Modules allows the Platform to be flat at the surface but to assume the bottom profile when in the bottom position (Fig.8 a,b). Because the overall surface of the Platform is bigger at the bottom then at the surface, when the tray approaches the surface its uneven part (non - horizontal) slides under the horizontal part in this way reducing the area. The sloped part of the Platform can slide under the even one thanks to the special sliding rivet connecting th Platform with the Leading Nut of the Elevating Module (fig.9). The Driving Shafts can be sloped thanks to the universal joints installed on them close to the gear boxes of the Elevating Modules (driving shafts always enter the gear box of the elevating module at the straight angle). Because the tray travels more at the deeper part of the pool then at the more shallow one there must be the differences in gear ratios of the relevant devices - the tray has to move faster at (a,b,c,d) and slower at (e,f) (Fig 10 a,b).

(5) Even when the grates of the Platform are large (rescuing aspect of the Device empha-sized) and cannot stop the objects like stones or leaves from falling to the bottom, the light plastic foil cover can be spread on top of it and attached to its edges in order to seal the unused pool. Such cover, unlike the existing ones does not have to be strong and resistant as it is supported by the sturdy Platform in this case.
CONDITIONS: a) The platform can be moved upward or downward only when no people use the pool exept for the emergency situation.
b) The Platform can be stopped only either when completely over the surface or if at the bottom position.

Claims (8)
1. The inventive idea of the Submersible Safety Device: a) protection from falling b) device of rescue c) ease of convertion from a) to b) and vice versa. At its upper position it is a protection device but bringing it to the bottom 1) enables normal utilization of the pool (swimming is not obstructed), 2) the device is becomming a safety tray which by activation (safety button or remote control device) can bring a swimmer to the surface of the pool no matter how deep in the water the drowning person can be.
2. Submersible Platform plastic mesh or grates (louvres) on the sturdy frame designed according to the shape of the pool.
3. Elements of the design which allow to adjust the Platform to the pool bottom profile (Platform segmentation, sliding rivet attachment, adjustable gear ratio of the Elevating Modules).
4. Elevating Module with built-in worm or cone gear. Modular construction of the PEM which allows easy assembly and disassembly of the Device. Only Elevating Module is to be attached to the wall of the pool and thanks to it no changes to the pool design have to be made.
5. Use of universal joints and snap-on extensions on the Driving Shafts which enable custom tailoring according to the pool shape.
6. Cone gear connections of the Driving Shafts which allow the Device to be run from one source of power (one electric motor).
7. Proposed use of plastic materials which prevent from electric shock (electric motor and installation is completely separated from the pool water) as well as from the corrosion of the components in the water.
8. Possible use in any kind of water receptacle not necessarily considered for recreation purposes (like agricultural reservoir, fire protection receptacle, etc.).
