Description

DEVICE FOR MOVABLE COVERAGE, PARTICULARLY FOR SWIMMING POOLS Description of the invention The present invention relates to a movable cover device, in particular, for swimming pools, play areas or the like, and more particularly, for swimming pools of average-sized swimming, such as private swimming pools. Movable cover devices for swimming pools are known from US Patent 3 854 149 and 3 209 373. Mobility is to cause the cover itself to move from a position in which it forms a cover over the swimming pool to a position in which the roof forms a shelter from the sun or rain over a terrace or the like, formed in the proximity of the pool. The structure described in US Pat. No. 3,854,149 is of the rotary type. The cover is formed of articulated panels. To put the device in the shelter position, it is necessary to install support columns. According to US Pat. No. 3,209,373, the cover itself is supported by rotating arms. In the shelter position, the structure is unstable, particularly in the presence of wind.

REF: 27586 The Soviet patent 318 237 describes a movable cover device for stadiums. Each cover panel is supported by two oscillating arms that form a deformable parallelogram. Such a device is very expensive to produce if good results are required in terms of operational quality, stability, safety and reliability. The object of the invention is therefore to propose a movable cover device which is simple, stable and reliable. According to the invention, the movable cover device for swimming pools, play areas or the like, comprises a roof which is movable between a collapsed position in which it covers, in a substantially sealed manner, a first region, the which can be a swimming pool, play area or similar, and an elevated position in which the roof covers, at a certain height, a second region which is displaced cor. Regarding the first region, the roof has a first edge on the side closest to the first region and a second one. : edge opposite the first c :: e, the device also buy me a structure that cer.e a joint with the ground and a joint z z r. the ceiling at a distance from the second edge, and having, starting from the articulation. with the ground, a guide ::: cr.erai that goes from the security, na ***** region to the first region when the roof is in the down position, is characterized by support means to support the roof in the vicinity of the second edge, when the roof is in the raised position, the roof is spaced apart from the support means when it is in the folded position. The support means can and preferably are permanently arranged at a certain distance from the first region such as a swimming pool. I dont know use when the roof is in the down position. In the raised position, the roof is stabilized by the support means. This makes it possible to provide the roof in such a way that it consists of a relatively heavy and / or bulky assembly or assembly, capable of covering a swimming pool or the like, which has a relatively large size and which has for example, the appearance of a conventional roof. A relatively heavy structure is capable, due to its own weight of closing in a substantially sealed manner, the periphery of the first region when the roof is in the down position. Therefore, it is possible to protect the first region from the intrusion of small animals or insects. If the roof is opaque, the development of algae and other phenomena due to light due to light are prevented. particular, due to the fot = ir.rresis. < Preferably, the device comprises means for lifting the second edge of the roof to its defined position by the support means. It is advantageous if the lifting means consist of a winch or the like 5 coupled to a traction cable that extends between the roof and a position close to the support means, so that when pulling the cable, the roof, the which is initially in the depressed position, is pulled along a path that leads the second edge 10 towards the support means, with a spontaneous rotation of the rotating structure which also causes the elevation of the first edge. Therefore, it is essentially sufficient to operate the lifting means in order to cause the roof to move from its lowered position to its raised position. Other characteristics and advantages of the invention will arise further from the following description related to a non-limiting example. In the attached drawings: Figures 1 and 2 are schematic perspective views showing the device according to the invention with the roof in the raised position and in the folded down position respectively; -3 Figures 3, 4 and 5 are schematic cross-sectional views showing the device of the Figures 1 and 2 in the lowered position, in the intermediate position during an operation and in the elevated position respectively; Figure 6 is a perspective, cut-away view of the support means; and Figure 7 is a side elevation view of the support means when the roof is in the raised position. In the example shown in Figures 1 to 5, the movable cover device 1 comprises a roof 2, which the device allows to move between a collapsed position (Figures 2 and 3) in which the roof 2 forms a closure on a first region, which in this example consists of a rectangular swimming pool 3, and an elevated position (Figures 1 and 5) in which the roof 2 is a shelter from the sun or from the bad weather above the second such region as a terrace 4 adjacent a terminal 20 longitudinal ß of the pool 3 ne swimming. In the example is: ranc, the roof 2 has the ::: c of a convincing roof. r: n two oblique panels closed at each end by a triangular vertical wall 3.

The roof is made of an opaque material and comprises a rectangular lower peripheral edge 9, designed and sized to be supported in a substantially sealed manner on the rectangular periphery 11 of the swimming pool 3. The periphery 11 includes the edge 6 mentioned above. If necessary, a sealing joint can be adjusted to the edge 9 of the roof to rest against the periphery 11 of the swimming pool 3 when the roof 2 is in the lowered position. It is also conceivable that the lower edge 9 is large enough to surround the periphery 11 of the swimming pool 3 and lean for example on concrete, mosaic pavement environments formed around the swimming pool 3. It is preferred, as shown in the illustrated example, that the raised position and the lowered position of the roof 2 be parallel to each other, but it is also conceivable, for example, in the case of a roof with a single roof panel, that the The last one is horizontal in the lowered and inclined position in the raised position. The device comprises an articulated structure formed in this example by two parallel rotating columns 12 comprising a first articulation 13 with the edge 6 of the pool 3 ne swimming and a second articulation 14 with the roof 2. the joints 13 and 14 < 3 have parallel axes with edge 6 of the swimming pool. With respect to a vertical plane P (Figure 3) parallel with the axes of the joints 13 and 14 and passing through the center of gravity G of the roof 2, the joint axis 5 is located to be displaced towards a first edge 16 of the roof 2. The first edge 16 of the roof 2 is which moves over the swimming pool 3 when the roof 2 moves from one to the other of the elevated and folded positions. The result of the above is that the weight of the roof 2 tends to cause the latter to rotate towards the terrace 4 around the joints 14. When the roof 2 moves from its lowered position to the raised position, the pillars 12 move from a position lying on the 3 swimming pool, shown in Figure 3, to an erected position shown in Figure 5, in which the columns 12 support, more particularly, the region of the first edge 16 of the roof 2. Resilient means or springs 15, produced for example in the form of gas cats, they fit between columns 12 and the ground and drive the columns 12 towards the extended position. In the example shown, the plane Q (Figure 5) passing through the axes of the joints 13 and 14 is inclined towards the terrace 4 when the roof 2 is located. in the raised position. By means of this arrangement, the roof 2 can, in the collapsed position, cover a swimming pool having a width of for example 5 meters, without the roof 2 being positioned at an excessive height in the raised position. It can be seen in effect in Figure 3, that due to the inclination of the plane Q, the columns 12 do not need to extend over the entire width of the swimming pool 3 when the roof 2 is in the down position. Furthermore, in the example shown, the inclined arrangement of the plane Q is made even more beneficial by tilting the roof panel facing the swimming pool 3, because the inclination of the plane Q allows the hinge shaft 14 to be placed higher. The distance between the axes 13 and 14 is thus increased by a given distance between the peripheral lower edge 9 of the roof 2 and. terrace 4 when the roof is in the elevated position. It would have been possible to produce the inclination of the plane Q with straight columns 12 arranged with an inclination when the roof 2 is in the raised position. In the example shown, it has been preferred to give the rotary columns 12 a flexed or curved centigrade with a substantially vertical lower section and an inclined upper section 17, the second region 4? E being a way which corresponds to the inclination of the panel 7. of the roof 2 when the roof 2 is in the raised -a-position. Thus, the roof 2 in the raised position is spliced against the upper section 17 of the columns 12. This reinforces the stability. In addition, the columns 12 whose visible lower section is vertical, are in most of the cases preferred from the aesthetic point of view. The device according to the invention further comprises means 18 for supporting the roof 2, when it is in the raised position, in the region of its second edge 19, opposite the first edge 16. The second edge 19 is which moves on the terrace 4 when the roof 2 moves from one to the other of its elevated and folded positions. The means 18 comprise a stationary pole or mast 21 which is secured to the ground in a position adjacent to the edge of the second region 4 (terrace) which is far from the first region (swimming pool) 3.

As shown in Figures 1 and -5, the roof 2 is supported by the pest mast 21 when it is in the raised position in the region of its second edge 13.

When the roof 2 is in the down position, trie the roof, and in particular the second edge 19, be separated from the pole or mast 21. The device ie a certain movable also buy me means to pull the arm 19 towards the mast 21 / to lift the second r. ? substantially to the party top of the mast 21 c arcr is it necessary to raise the ternr from the folded position of Figures 2 and 3 to the elevated position of Figures 1 and 5. The lifting means comprise a winch 22 (Figures 3 to 5) having the ability to be put into operation manually or by an engine, the manual method is preferred due to its reliability and simplicity. On the winch 22 one of the ends of a cable 23 is wound which extends as far as the region of the edge 19, which should be brought closer to the mast 21 when the roof is in the raised position. Between the winch 22 and the edge 19 of the roof, the cable 23 passes over a return pulley 24 in the upper part of the mast 21 and through a mobile support or carriage 26 mounted in such a way that it moves freely along the mast 21, which is formed as a lane for this car or mobile support (see Figure 6). The carriage 26 and a bracket 27 fixed to the edge of the roof 2 carry pulleys 28 and 29 respectively, by means of which the cable 23 makes several forward and backward travels between the carriage 26 and the bracket or bracket 27. The end 31 of the cable which is remote from the winch 22 is coupled, in the example shown, to the carriage 26. The upper part of the mast 21 also carries an automatic coupling device 32 of the type attached to the rear of the camier.es and the bracket or bracket 27 carries a coupling ring 33 compatible with the automatic coupling device 32. A release control 34 extends from the automatic coupling device 32 to a point which is easily accessible to an operator, for example, at a height 1.5 meters above the mast 21. On the floor surface of the terrace 4 a slit 36 is also provided, which extends between the base of the mast and the edge 6 of the swimming pool 3. The slit 36 is placed in the same vertical plane as the one followed in the bracket 27 when the roof moves from the raised position to the lowered position or vice versa. Now, the operation of the covering device according to the invention will be described. When the roof 2 is in the down position (Figures 2 and 3), the columns 12 are in the position extended above the swimming pool 3. The carriage 26 on the one hand and the bracket or gusset 27 with pulleys 29 on the other hand are retracted into the slot 36 in the floor surface of the deck 4, also as are trames cable forming the gasket between the carriage 26 and the bracket or bracket 27. In order to make the roof 2 move to the raised position, it is sufficient to operate the winch 22 in the direction of wire pull 23. The second edge 19 of the roof 2 is also pulled into the mast 21 and this drives the columns 12 to rotate up to its joint 13 with the ground as shown in Figure 4. this compresses the springs 15. During lifting, the carriage 26 itself assumes, at all times, a height position along the mast 21 such that it is in equilibrium with respect to the various forces or vertical components of force acting on it. When the cable 23 has been sufficiently wound for the length of the cable, the lengths or lengths between the pulleys 28 and 29 are minimal, the pulleys 29 carried by the roof 2 are located substantially below the pulleys 28 of the carriage 26, which is located substantially in the upper part of the mast 21. The end of the movement causes the coupling of the ring 33 in the automatic coupling 32 to end in the situation shown in Figure 7. In the raised position, it is the tension of the cable 23 which holds mainly the second edge 19 of the roof 2 at the desired height. This function of fixing the cable 23 is provided by the winch 22, which is normally designed to oppose any unwinding movement of the cable 23 under the effect of the tension in the cable 23. The coupler 32, 33 has a safety function for cases of rupture of the cable 23. The coupling 32, 33 further has a function of horizontal immobilization of the edge 19 with respect to the mast 21. In order to cause the roof 2 to move to the lowered position, the release of the coupling 32, 33 by means of the control 34 and then the winch 22 is put into operation in the unwinding direction. As the cable is unwound, the edge 19 of the roof loses height and at the same time the springs 15 propel the rotary columns 12 towards their extended position. The reverse movement of the previously described one occurs until the depressed position is obtained, as shown in Figures 2 and 3. The invention is, of course, not limited to the example described and illustrated. There could be at least two masts such as 21 and / or two cables capable of being driven by the same winch or by two different winches capable of being synchronized. It is also possible to replace the mast 21 by a fixed structure on an existing structure such as a facade or a similar structure. In particular, in the case where there are at least two masts, the number ie rotating columns could be reduced to only one. 5? there are several columns, these could be joined by transverse pieces that have, in particular, the purpose of synchronizing them better in their rotation around the joint 13 with the ground. The carriage, such as 26, is not indispensable and it would be possible to connect the cable directly from the top of the mast or similar to the roof, such as 2. The disadvantage would then be that the cable does not sink when the roof is in place. the downcast position. It is not essential to fix the roof 2 in the raised position. It is also possible to fix it with means other than those with the automatic coupling described and illustrated. For example, the edge 19 of the roof could, when sliding along the mast at the end of the movement towards the elevated position, pass over an asymmetrical projection, from which it could not be subsequently separated by itself as long as the winch does not is put into operation in the unwinding direction. When such a movement of the winch occurs, springs such as 15 push the columns 12 towards the extended position, separate the roof 2 from the mast 21 and thus separate the edge 19 from the projection provided along the mast. Other means could be that the projection can be retracted by means of an accessible control at the base of the mast face freeing the edge 19 of the roof when the operator wishes to carry out a return maneuver from the roof 2 to the folded position. In the case in which there is only one rotating column, its articulation with the roof can be of the ball joint type to allow adjustment of the roof inclination, by means of two independently controlled winches, each one associated with one of the two fixed masts. Between each fixed mast and the roof, each wire preferably extends in a vertical plane that passes through the center of the ball joint. It is possible to increase the stability of the assembly or assembly by means of two jacks mounted between the rotating column and the roof in an oblique position on each side of the rotating column. It is noted that, in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it refers. Having described the invention as above, property is claimed as contained in the following
