Definitions

• the invention relates to the technical sector of water filtration in swimming pools.
• the part immersed in water may have arrangements acting as a staircase.
• the part immersed in water has a generally rounded shape, incorporating the stair treads and receiving the filtration system.
• This part immersed in water is connected to the above-ground part, which receives the suction and discharge means.
• the part immersed in water is not integrated into the pool panels, but is arranged in superposition of the latter, which must be shaped to delimit a rounded surface corresponding to that of the staircase.
• the object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
• the problem which the invention proposes to solve is to produce a filtering staircase shaped to be mounted directly with adjacent panels constituting the swimming pool basin, bypassing the problem of sealing, while having the objective of achieving a staircase whose cost is particularly reduced, and which can easily and quickly be installed, while keeping a very high filtration efficiency, with the possibility of adding additional functions.
• a filtering staircase for swimming pools has been designed and developed, characterized by the combination of the following arrangements:
• the body of the staircase delimits a hollow closed volume obtained by rotational molding to form a reservoir whose front face has steps
• the reservoir is in communication with the water in the basin, the reservoir has internal arrangements capable of allowing the mounting of a filtration system in communication with the water contained in said reservoir,
• the face of the body opposite that showing the steps, has arrangements for mounting and fixing a box obtained by rotational molding and in which the suction and discharge means are mounted in combination with the filtration system,
• the body laterally has arrangements for fixing the adjacent panels constituting the swimming pool basin.
• the entire filtering staircase is produced by rotational molding, a technique perfectly known to a person skilled in the art, but which has never been used for the production of a filtering staircase.
• This rotational molding technique proves to be particularly advantageous for the envisaged application, since a perfectly sealed tank is directly obtained during manufacture, in which the filtration means can be mounted, in combination with specific arrangements .
• the internal arrangements, for mounting the filtration system are constituted by ribs formed in the bottom of the reservoir, directly during rotational molding, said ribs allowing, in combination, the support of a support plate having connecting members, with the filtration system as such.
• connection members consist of an elbow pipe disposed between two ribs, one end of the pipe emerging from the plate to be connected to the base of at least one support receiving a filter bag, the other end of said pipe, opening at the level of the tank connection arrangements, with the box receiving the pumping means.
• the upper part of the support receiving the filter bag (s) is tightly connected, in a sole, it even made integral in a sealed manner, with a chimney formed at the upper level of the tank, in communication with an access hatch closed by a removable cover.
• the pipe mounted in the plate and connected to the filtration system, is connected at the suction outlet of the pump, the outlet of which is connected to a pipe opening at one of the staircase steps of the tank.
• the arrangements for mounting and securing the box receiving the suction and discharge pump consist, on the one hand, of props formed during rotational molding of the tank and on which said box is supported and, on the other hand, by a centering preform cooperating in an opening formed in the box, said preform, which constitutes a hollow body, receiving the suction and discharge pipes.
• Another problem which the invention proposes to solve is to be able to integrate other functions into the filtering staircase.
• one of the steps has, at its horizontal face, directly during rotational molding, ribs delimiting hollow spaces, to be in communication with an air intake connected by a pipe to a member arranged in the technical box, said step receiving a microperforated plate.
• the arrangements for fixing the adjacent panels are constituted by lateral wings in the thickness which are embedded metal inserts adapted to receive fasteners.
• the front face of the tank, at the steps has a U-shaped flange , receiving a screwing support, covered with a seal, for fixing a liner cut to the U shape, and fixed in the support by means of screws covered with a protective strip.
