[0001] The invention relates to a cover system for a swimming pool and a method for covering
a swimming pool.
[0002] Swimming pools are commonly covered when not in use, for example in winter season.
A known system for covering a swimming pool is to displace a flexible cover, e.g.
a PVC sheet, over the swimming pool. The edge of the flexible cover is then anchored
to the perimeter of the swimming pool with suitable fastening means.
[0003] The disadvantage of this technique is that the flexible cover tends to form a central
concavity under its own weight. This concave arrangement leads to rainwater stagnation
and unsatisfactory hygiene. It is also unsafe especially for children that may remain
trapped in the central, concave portion, in particular when the flexible cover is
wet and slippery.
[0004] These disadvantages, according to the invention, are solved by a system for covering
a swimming pool, comprising a flexible cover adapted to be displaced over the swimming
pool and floating, inflatable support means to be placed on the water of the swimming
pool and under said flexible cover, wherein said support means, when inflated, are
adapted to push upwards a portion of the flexible cover, thus resulting in a substantially
convex arrangement of said cover.
[0005] Said floating, inflatable support means are preferably in the form of one or more
cushions filled with pressurized air.
[0006] If more than one cushion are provided, the cushions are preferably aligned at the
centre of the swimming pool and following its longitudinal axis. Each cushion is preferably
secured to the next by suitable means, for example an elastic.
[0007] In a preferred embodiment, said air cushion(s) is/are fitted with watertight valves
for pressurized air supply, to allow on-site inflation. Both the cover and the air
cushion(s) may be made of PVC with, if appropriate, a suitable coating.
[0008] The perimetral edge of the flexible cover is anchored with suitable means, which
are known per se.
[0009] According to the invention, a method for covering a swimming pool comprises the steps
of:
- a) providing at least one floating, inflatable support means on the water of the swimming
pool;
- b) providing a flexible cover over the swimming pool, so that said support means remain
under the cover, and anchoring the perimetral border of said flexible cover with suitable
means;
- c) inflating said support means, so that they push upwards a portion of the flexible
cover, thus resulting in a convex arrangement of said cover.
[0010] Step a) is preferably performed with the inflatable support means partially inflated,
so that they easily float on the water surface. During step c), they are fully inflated
to push upwards the cover leading to the aforesaid convex arrangement of the same.
[0011] The invention provides easy mounting and hygienic, safe operation. In particular,
the convex arrangement of the cover, having substantially a central region raised
with respect of the perimetral region, avoids rainwater stagnation and the risk of
falling and remaining trapped on the cover, especially for children.
[0012] The invention is now described with greater detail and referring to the figures showing
a preferred embodiment, wherein:
Fig. 1 is a cutout view of a cover for swimming pool, in operation, according to the
invention;
Fig. 2 is a top view of the cover of Fig. 1.
[0013] Referring to the figures, a swimming pool 1, filled with water, is covered with a
flexible PVC sheet 2 which is secured, along the perimetral border, with suitable
fastening means 3.
[0014] A floating air cushion 4 is provided, which maintain a central portion of the flexible
sheet 2 in a raised position, with respect to the perimetral region, as shown by Fig.
1.
[0015] Water level of the swimming pool is shown as W. The flexible sheet 2, under the pushing
action of the floating air cushion 4, remains in a substantially convex arrangement
as shown.
[0016] Referring to Fig. 2, two cushions 4 and 5 are provided, according to the length of
the swimming pool. Cushions 4 and 5 are secured each other by an elastic 6 fitted
into suitable rings or handles 7. Each cushion 4, 5 is fitted with a watertight valve
8 for the connection of an air supply tube 9. Air cushions 4, 5 can also be made of
PVC.
[0017] It should be appreciated that a suitable number of floating cushions may be used,
namely one or more cushions, depending on the length of the swimming pool. Preferably,
the air cushions cover substantially the whole length of the swimming pool and are
placed in the centre, over the longitudinal axis, as seen in Fig. 2.
[0018] It should also be noted that the size and shape of the air cushions 4, 5 may vary
according to the needs. For example they may be realized in a variety of shapes for
different swimming pools.
[0019] The fastening means 3 are realized according to known technique. For example, the
cover edge is folded and welded to form an anchoring slot, and said slot is secured
by a metal ring which in turn is fixed to suitable anchoring means. This however pertains
to known technique, and is not further described.
[0020] Referring to Fig. 2, the method for covering the swimming pool 1 comprises the following
steps.
- a) Air cushion 4, 5 are placed on the water of the swimming pool. During this step,
the cushions 4, 5 may be partially filled with air, so that they can easily float.
- b) The flexible cover 2 is displaced over the swimming pool and the perimetral region
of said cover 2 is anchored to the border of the swimming pool in a suitable manner.
- c) Air is fed through the air pipes 9 connected to valves 8, so that the cushions
4, 5 are inflated, until the flexible cover 2 has the substantially convex arrangement
of Fig. 1.
[0021] The invention thus achieves the afore mentioned purposes, namely a hygienic and safe
covering of a swimming pool.
