Modular pool comprising a support structure placed around a containment basin for the water and comprises a plurality of metal plates, joined together, which comprise a base for resting on the ground, an upright at least partially above ground, and lateral edges provided with a reinforcement flange. The pool also comprises fixing elements fixed to the base of the metal plates and anchored to the ground, a waterproofing layer placed to coat a bottom and a lateral surface of the containment basin, and a surface finish layer placed to cover the waterproofing layer.

The invention discloses a pool body, including: a pool inner wall including a side wall and a bottom wall which are connected, the side wall and the bottom wall of the pool inner wall forming a water holding cavity for storing a fluid; an additional chamber arranged on the pool inner wall; and an additional pipeline built into the additional chamber. The invention can save the space in the pool.

A prefabricated self-supporting module for making building structures, more particularly swimming pools, is provided. The module comprises a matrix made of foamed material and a supporting structure made of metal coupled to the matrix. The supporting structure made of metal may be embedded in the matrix made of foamed material (internal supporting structure) and/or cover the matrix made of foamed material (external supporting structure). Thanks to the provision of the supporting structure made of metal, the module is self-supporting, and it does not need any further reinforcements of reinforced concrete. Thanks to the provision of the supporting structure made of metal, the module can be used for making structural supporting elements such as floors, side walls, and so on. This module can be completely made and finished in the factory, so that the steps to be carried out on the construction site are extremely limited, with consequent economic saving.

A pool, preferably a plunge pool, that can be prefabricated and on site installed in a short space of time is provided. The pool is integrally formed, resulting in a unitary pool shell having a floor, one or more sidewalls connected to the floor, a surface, such as a step or bench, extending from at least one of the sidewalls; and a peripheral wall extending from the surface to the floor.

The present invention provides a above ground pool, comprising a flexible pool body. The flexible pool body comprises: a polygonal bottom sheet that comprises a plurality of edge portions; and a plurality of side sheets, each side sheet comprising a pool sidewall portion and a pool bottom portion, and each of the pool sidewall portions and each of the pool bottom portions being in the shape of an isosceles trapezoid. Each of pool sidewall portion comprises a first upper-base portion, a first lower-base portion and a first middle portion defined between the first upper-base portion and the first lower-base portion, and each of the pool bottom portion comprises a second upper-base portion, a second lower-base portion and a second middle portion defined between the second upper-base portion and the second lower-base portion. The first lower-base portion and the second lower-base portion coincide to define a junction of the pool sidewall portion and pool bottom portion. The first middle portions of the side sheets are successively connected to form a side wall of the above ground pool and the second middle portions are successively connected to form an outer ring of the bottom of the above ground pool. The second upper-base portions of the pool bottom portions are respectively connected to the edge portions of the bottom sheet. In the above ground pool of the present invention, joints are moved to a side wall of the swimming pool or the bottom of the swimming pool as much as possible, thereby reducing the length of joints passing through a heavily stressed area to the greatest extent, simplifying production processes, reducing costs, and reducing the probability of water leakage from the above ground pool.

A swimming pool wall having a drainage groove. The side wall (2) of the swimming pool and the drainage groove (10) are formed from a single piece of material. The slope wall (4) of the drainage groove (10), which is linked to the side wall (2) of the swimming pool, directly adjoins the swimming pool overflow edge (3).

Speed reduction gear comprising two intermediate transmission lines, in particular for a turbine engine, comprising an input line (12) and an output line that is driven by the input line via said intermediate transmission lines, said intermediate transmission lines being substantially parallel, characterized in that said reduction gear comprises means for distributing loads between said intermediate lines, said load distribution means comprising swiveling coupling means (30) for rotatably coupling one end of the input line, and oil-damping means (40, 50) for damping radial movements of an opposite end of the input line.

A portable kiddie pool includes a main basin including a floor and a perimeter wall defining a perimeter of the pool, the floor including a radial groove that extends towards the perimeter of the pool, a fountain basin disposed above the floor within a perimeter of the perimeter wall, the fountain basin including at least one fountain opening, and tubing that extends at a first end from the perimeter of the pool through the radial groove of the floor to a second end that operably connects to the at least one fountain opening of the fountain basin, the tubing including a fitting configured to connect to a pressurized water source such that water from the pressurized water source flows from the pressurized water source through the tubing and to the fountain opening of the fountain basin.
