- A swimming pool comprising a tank is known in the art. This tank comprises a bottom drain connected to a water treatment plant for treating the water contained in the swimming pool. This treatment plant comprises a pump that draws water from the tank via the bottom drain. For example, the existing bottom drains have a square or circular shape of different sizes according to the flow rate of the water that is drawn from the swimming pool.
- A grate is also known to be used to cover the bottom drain. The grate prevents objects and/or possibly swimmers that use the swimming pool from getting caught in the bottom drain.

- That is, the suction force exerted by the pump of the treatment plant connected to the bottom drain of the prior art swimming pool may potentially cause a part of the body of a user of the swimming pool to be sucked in and trapped in the bottom drain. Children are most exposed to the risk of being trapped in the bottom drain, due to their small size.
- The safety problem of prior art bottom drains is even more serious if the grate is removed or damaged.
- Whenever a person gets caught in the bottom drain, if not promptly rescued, he/she may drown.
- Therefore, the technical purpose of the present invention is to provide a modular element for at least partially defining a bottom drain of a tank that can obviate the problems of the prior art.
- In particular, an object of the present invention is to provide a modular element adapted to at least partially define a bottom drain through which water can be efficiently drawn from the swimming pool tank, while preventing objects and/or parts of the body of users of the swimming pool from being trapped and/or suctioned.
- A further object of the present invention is to provide a kit for building a bottom drain of a tank of a swimming pool, comprising at least one pair of modular elements.
- The aforementioned technical purpose and objects are substantially fulfilled by the modular element and the kit comprising the technical features as disclosed in one or more of the accompanying claims.
- The modular element as described herein, in addition to defining a bottom drain that affords efficient suction and recirculation of the water in the tank of a swimming pool, ensures a safety level for use of the swimming pool according to the requirements of UNI EN 13451-3 and UNI EN 16713-2 standards.

main body 2 has a cut-offportion 27 proximate to thetop 22. This cut-offportion 27 is configured to project out of said wall of the tank and is removable to define asuction port 271 configured to provide fluid communication between the throughchannel 23 and the tank. In other words, once theinsert portion 26 of themain body 2 has been inserted into the wall of the tank, the cut-offportion 27 that projects out of the wall of the tank is removed to define thesuction port 271. - For example, if the
insert portion 26 is inserted into a bottom of the tank, this cut-offportion 27 is configured to project out of such bottom of the tank. - Preferably, the cut-off
portion 27 extends along the first direction X-X to define a second height H2 ranging from 10 to 60 mm, more preferably of 35 mm. - It should be noted that, when the hydraulic circuit is connected in fluid communication with the through
channel 23, the tank is in fluid communication with this hydraulic circuit via thesuction port 271. - This
suction port 271 has a first dimension of 5 to 10 mm, preferably 8 mm. Advantageously, this specific dimension of thesuction port 271 prevents objects and/or limbs of users of a swimming pool from being caught insuch suction port 271. - Due to this dimension of the

Thesecond zone 232 and theintermediate zone 233 are located at theinsert portion 26 of themain body 2. - Preferably, one side of the
first zone 231 coincides with the first dimension of thesuction port 271. In other words, one side of thefirst zone 231 has a dimension of 5 to 10 mm, preferably 8 mm, as the first dimension of thesuction port 271. - Still preferably, the

side wall 28 has a thickness of 4 mm. - Still preferably, the anchor means of the
main body 2 are formed of one piece with theside wall 28 of themain body 2. - Still preferably, the anchor means
comprise fins 29 projecting away from theouter surface 282 of theside wall 28. If the wall of the tank is made of concrete and theinsert portion 26 of themain body 2 is inserted before the concrete sets, the concrete sets around thefins 29, thereby anchoring themain body 2 to the wall of the tank. - According to the preferred embodiment of the invention, the
side wall 28 of themain body 2 comprises throughcavities 283 at theinsert portion 26 of themain body 2. These throughcavities 283 assist the anchor means in keeping themain body 2 stuck in the wall of the tank. That is, again, if the wall of the tank is made of concrete and theinsert portion 26 of themain body 2 is inserted before the concrete sets, the unset concrete fits into the throughcavities 283 and sets inside such throughcavities 283, thereby anchoring themain body 2 to the wall of the tank. - Still according to the preferred embodiment of the invention, the
insert portion 26 of themain body 2 is contiguous to the cut-offportion 27 of themain body 2. Advantageously, since in use the cut-offportion 27 of themain body 2 is removed to define thesuction port 271, the cut-offportion 27 being contiguous to theinsert portion 26, thesuction port 271 will be level with the wall of the tank in which themain body 2 is inserted. In other words, if theinsert portion 26 is inserted into a bottom of the tank, thissuction port 27 defines the bottom level of the tank of the swimming pool. - The present invention also relates to a kit for building a bottom drain of a tank of a swimming pool. This kit is also suitable for the formation of a feed line of the swimming pool tank.
- This kit comprises at least one pair of
modular elements 1. Eachmodular element 1 of the pair ofmodular elements 1 corresponds to themodular element 1 as described herein. - This kit comprises at least one connecting
element 3. For example, the kit comprises a connectingelement 3 for each pair ofmodular elements 1 of the kit. As a further example, if the kit comprises threemodular elements 1, the kit comprises two connectingelements 3. - Each connecting
element 3 is configured to connect a respective pair ofmodular elements 1 so that the throughchannels 23 of themodular elements 1 of such pair ofmodular elements 1 will be in fluid communication with each other to at least partially define the bottom drain of a tank of a swimming pool. In other words, in use, each connectingelement 3 is interposed between a respective pair ofmodular elements 1. - Preferably, each connecting
element 31 comprises a respective throughchannel 31. When a connectingelement 3 connects a respective pair ofmodular elements 1, the throughchannels 23 of saidmodular elements 1 are in fluid communication with each other via the throughchannel 31 of said connectingelement 3. - Preferably, each connecting
element 31 has the same shape as the throughchannel 23 of themodular element 1. - It should be noted that the suction ports, defined by removing the cut-off
portion 27 of eachmodular element 1 of the kit, have a first dimension of 5 to 10 mm, preferably 8 mm, respectively. Also, the sum of the second dimensions of eachsuction port 271 defined using themodular elements 1 of the kit is about 1 m. In other words, a suction line is also defined by the kit. Therefore, the suction line so defined has a rectangular shape with a first side with a dimension of 5 to 10 mm, preferably 8 mm, and a second side having a length of 1 m. - According to the preferred embodiment of the invention, the kit comprises a
closure element 4 designed to be connected to amodular element 1 at arespective end modular element 1 to at least partially close a connectingopening channel 23 of thismodular element 1. Preferably, theclosure element 4 completely closes a connectingopening channel 23 of themodular element 1 to which it is connected. - Preferably, each
closure element 4 has the same shape as the throughchannel 23 of themodular element 1. - It should be noted that, if a swimming pool tank has a suction line defined by the
modular elements 1, this suction line meets the requirements as defined by the UNI EN 13451-3 and UNI EN 16713 standards. In order to fulfill the requirements of these standards, obstruction tests must be carried out. Thus, these obstruction tests were carried out on the suction line defined by themodular elements 1. In particular, the suction line analyzed has a rectangular shape with a first side of 8 mm and a second side of 1 m. The obstruction tests were carried out by applying an oval 285 x 90 mm obstruction device with an elastomeric foam plate simulating the consistency of a human body, along this suction line. The test was carried out by simulating a maximum suction flow rate of 14,40 cubic meters/h and applying a vacuum of 90 kPa. The obstruction device came off the suction line with a force considerably lower than 300 N, which is the maximum value allowed for the test to be passed. The force value was measured using a precision digital dynamometer. - Therefore, the suction line defined by the
modular elements 1 in a tank of a swimming pool, ensures an adequate level of safety of use of the swimming pool itself.
