OBJECT OF THE INVENTION
[0001] The present invention relates to a device initially conceived to protect swimming
pools, but also applicable for covering other type of tanks.
[0002] The device is constituted by a cover attached to some profiles provided with rolling
elements on their ends, thereby facilitating its retraction and positioning using
a reel placed on one end of the pool.
[0003] The device of the invention protects persons and animals from the risks related to
falling into the swimming pool, while keeping the pool clean by preventing the entry
of foreign objects. It also facilitates the extension and retraction of the cover
that forms part of the assembly of the device.
[0004] The reel fixed on one end of the pool allows collecting the cover. It has a profile
on one of its ends that increases the winding diameter, thereby reducing the number
of turns needed to collect the cover.
BACKGROUND OF THE INVENTION
[0005] Devices for covering swimming pools are known that consist of a plastified fabric
cover with a number of transverse profiles that sustain the cover preventing it from
sinking in the water and provided with elements to facilitate its extension and retraction.
[0006] The object of these swimming pool covers is to cover the pools when they are not
used, in order to prevent accidents such as children or animals falling in them.
[0007] Pools are covered by covers of this type in winter to prevent leaves and dirt in
general from falling into the pool.
[0008] Devices of this type are described in patent documents such as document with publication
number
EP0724049, which protects a roll-up covering device for pools with transverse reinforcements
in the form of triangular profiles, the base of the triangle resting on the edge of
the pool. The sides of the profiles have a suitable curvature for allowing the assembly
to be rolled up.
[0009] Patent document with publication number
EP1564347 protects another swimming pool cover with a number of parallel and transverse stiffening
rods and tension cables joined on the sides to facilitate winding it.
[0010] Document
FR2763089, disclosing the features of the preamble of claim 1, describes a roll up cover for
a swimming pool, having a flexible cover with its size and shape adapted to that of
the swimming pool. Reinforcement rods extend across the cover and rest at their ends
on the edge of the pool. A shaft for rolling up the cover is connected at one end
to the cover and to a drive motor. Each reinforcing rod has an opening formed at the
top of the edges of the pool. Rollers are provided to roll on the edges during rolling
und unrolling of the cover.
[0011] Currently known swimming pool covers can be wound using a collection device consisting
of a small machine with a handle, which rolls up the cover and rods on the end bar
with the cover extended on the floor without moving, thereby rolling up the fabric
and the tubes advancing until reaching the end.
[0012] In this way, this device does not move the cover but instead is wound upon itself
together with the profiles and the cloth.
[0013] To execute the winding a person must move along the entire length of the pool. The
winding is performed on the cloth, so that the dirt gathered on it stays there in
the final roll produced.
[0014] In currently known covers, as mentioned above, the ends rest on the edge of the pool
and can be scraped and damaged in the winding action.
[0015] With the device of the present invention the cover is retracted to an end of the
pool, where the fixed reel is placed, so that the dirt is not contained in the collected
roll and the assembly does not scrape against the edge of the pool.
DESCRIPTION OF THE INVENTION
[0016] The device of the invention, as defined by claim 1, is constituted by a swimming
pool cover or the like to be collected, and a reel that remains fixed while the cover
is extended or retracted.
[0017] The cover is made of a single piece and is provided along its entire length of guides
that are attached to rigid transverse profiles.
[0018] The rigid transverse profiles are provided with:
- A lower central groove for connection to the cover guides and insertion on each end
of a protrusion of a profile supporting the rolling elements; and
- Corresponding lateral grooves for inserting, in each end of the transverse profiles,
the lateral protrusions of said profiles supporting the rolling elements. These grooves
can also be used to insert straps that connect the cover to the reel, as well as straps
for pulling and dragging the cover when it is extended.
[0019] The profile supporting the rolling elements is provided with:
- An upper central protrusion for inserting the transverse profile in the central groove;
- Two lateral protrusions in the top part in a clip arrangement for insertion in the
end grooves of the transverse profiles; and
- C-shaped extensions on the ends for inserting the rolling elements.
[0020] The rolling elements facilitate the retraction and extension of the cover with its
stiffening elements to the fixed reel.
[0021] The profile supporting the rolling elements determines a separation between the transverse
profile and the ground that allows the profiles to pass over the edge of the pool,
preventing a direct contact of the transverse profile with the ground and the protrusion
of the pool edge.
[0022] In addition, as the profiles supporting the rolling elements are placed on the ends
of the rigid transverse profiles, they block a possible escape of the cover guides
inserted in the central groove of the transverse profiles.
[0023] The guides are made of the same continuous material of the cover, stuffed with a
stiffening material.
[0024] The cover has straps for attachment to the fixed reel, so that to retract the cover
when it will be removed from the pool it suffices to tie the straps to the drum of
the reel placed on a side of the pool, retracting the cover.
[0025] This action is simplified by the rolling elements, which also prevent the cover from
scraping the edge of the pool.
[0026] The cover is collected by a reel which, in addition to the usual elements provided
in fixed reels such as a stand and a drum, is provided with segments attached to both
ends of the drum in order to reduce the number of turns required to roll up the device
of the invention by increasing the radius of the drum.
[0027] The retracted cover and profiles with rolling elements is very large and cannot be
performed with currently known reels, as the device when rolled up is too large and,
because profiles with their rolling elements are collected on each other in the rolling
operation, the circle produced is irregular. In addition, the weight of the profiles
makes them slide on the downward moving side of the reel, carrying the cover with
them, thereby forming a hanging bulge that unbalances the rolling operation and makes
it impossible.
[0028] For this reason, the reel of the invention is provided with radial segments on the
end of the reel drum, reducing the number of turns to make to a minimum and preventing
the accumulation of material on the drum.
[0029] The reel has a gear reducer driven by a conventional handle or an electric device,
thereby facilitating the winding action.
[0030] In addition, the reel is provided with a clutch system to release the rotation of
the main drum in order to pull on the end of the cover when unwinding and extending
it.

PREFERRED EMBODIMENT OF THE INVENTION
[0032] The device consists at least of the following:
- A cover (1) made of a plastic material of a suitable size for covering the surface
area of a swimming pool, provided with uniformly spaced transverse guides along its
entire length;
- Transverse profiles (2), provided with:
o A central groove (2.1) in which are inserted:
The transverse guides of the cover; and
On the ends of the central groove (2.1), profiles (3) that support rolling elements
through a central protrusion (3.1), which also acts as a stop for the guides, preventing
them from escaping the central groove (2.1).
- The profiles (3) that support the rolling elements, in addition to having the central
protrusion (3.1) and the lateral protrusions (3.2) for attachment to the transverse
profile (2), are provided with corresponding C-shaped end pieces (3.3) for inserting
at least one wheel (4) in each end piece (3.3). Introduced in said end pieces (3.3)
are corresponding grooved flanges in order to lock inside it the shaft of the wheel
(4) that facilitates the motion of the cover and improves its stability.
- A reel (5), its drum (5.1) being provided with segments (6) inserted radially in the
grooves (5.1.1), so that the working radius of the drum is increased by the length
of said segments. The segments (6), which in this example of embodiment are inserted
in the number of four in each end, are easily removable and insertable. The reel (5)
can be transported as it has wheels (5.2) on its base. It includes a gear reducer
that simplifies the action of winding the cover (1). The gear reducer is provided
with a clutch system.
[0033] The clutch system simplifies the action of unwinding the cover (1) by removing a
pin incorporated in said clutch system which, when removed, allows the drum to turn
freely.
[0034] At the time of unwinding the cover, straps are attached joined to a lateral groove
(2.2) of the transverse profile nearest the reel (5). When winding the cover on a
non-solid surface, the transverse profile (2) are partly pressed against the central
space and the wheel (4) will hang and protrude out of the ends of the reel structure,
pressing against each other and repositioning themselves.
[0035] The winding surface will not be circular but instead polygonal, divided into areas
or sides with a concave appearance in which the transverse profiles (2) are positioned.
This characteristic means that when it is unwound the cylinder does not gather momentum,
instead unwinding one by one without requiring a brake to control said momentum.
[0036] In a second example of embodiment, as shown in figure 4, two sets of segments (6)
are inserted in each end of the drum (5.1) at a certain distance from each other,
joined by pairs by means of tubes (7).
