The swimming pools built
a few dozen years ago were characterised
by their considerable depth.
Lately, however, in view of the fact that
the swimming pool is used for various different
purposes, they tend not to be so deep.
To adapt to this trend, "moveable swimming
pool floors" have been created, consisting
of units made of stainless steel designed
to reduce the depth of the pool without
the great expense that would otherwise be
incurred if the building work of the swimming
pool were to be radically modified.
This is not all. Recently, Patentverwag
Italia, the leader in the swimming pool
equipment sector also started production
of "moveable swimming pool floors"
with adjustable heights.
As a result, two separate types of "moveable
swimming pool floors" are available
on the market: the fixed type and the type
that is height adjustable.
The traditional type of "moveable swimming
pool floor", the one with the fixed
height floor surface, consists of rectangular
parts that are fitted together and have
four or six supports or "legs"
that hold up a surface consisting of a special
moulded polypropylene grating.
The height of the "surfaces" that
are made entirely of stainless steel can
vary from a minimum of 20-30 cm. to a maximum
of 150-180 cm.
Obviously, the moveable swimming pool floor
with adjustable height is a more complex
structure, supported by crossed over uprights
holding a large horizontal surface.
The surface is raised by introducing air
by means of a compressor into a tank.
Under the upward thrust caused by the air
emitted into the tank, the floor lifts to
the height required and previously programmed.
To close the structure, in other words to
lower the floor, the air simply has to be
let out of the tank with the automatic device
with the consequent return of the water
into the tank itself.
The "moveable swimming pool floor"
with adjustable height is used mainly in
swimming pools in which different activities
take place within a short space of time
from each other; for example pools in which
a game of water polo is played first for
which a regulation depth of at least 1.80
m. is required, followed by a course of
aqua gym involving the use of special equipment.
Patentverwag Italia is the leader of this
special market sector and has recently fitted
the public swimming pool in Sori (GE) with
a complex piece of equipment consisting
of a bulkhead and two types of moveable
swimming pool floors, both the fixed type
and the adjustable height type, in order
for the pool to be used to the full.
The "moveable swimming pool floor"
sector is expanding fast as pools are being
used in a more complex and varied way.
Numerous activities take place nowadays
in the pool: from swimming to water polo,
from aqua gym to underwater diving courses,
from swimming courses for children to the
training of athletes.
This is a reality that is evolving and making
the use of "moveable swimming pool
floors" in the two versions described
above almost essential.
