Definitions

  • the present invention relates in general to a swimming pool covering assembly, for covering a swimming pool when it is not in use, e.g. in the evening or in winter.
  • a covering assembly generally comprises a covering tarpaulin, usually made of synthetic material, which is supported by a system of mutually substantially parallel support beams installed at regular distances, the ends of which rest on the edge of the swimming pool.
  • swimming pool covering assemblies are known per se in practice. When the swimming pool is going to be used, the covering assembly is removed, e.g. by rolling it up.
  • the covering assembly When in use, the covering assembly has different functions. One function is to prevent dirt and leafs from ending up in the swimming pool.
  • the swimming pool covering assembly also has a safety function: although it is not intended that people walk over the swimming pool covering assembly, it must be able to withstand that; particularly, the swimming pool covering assembly must prevent playing children from falling into the water. In this context, it is of importance that the free end of the swimming pool covering assembly is fastened under tension to the fixed world. In practice, it often appears to be difficult to fix the swimming pool covering assembly correctly to the fixed world.
  • Figure 1 schematically shows a top view of a swimming pool covering assembly 1, comprising a covering tarpaulin 2 which is supported by a plurality of support beams 3, which are substantially parallel and which have their ends resting on an edge of a swimming pool, which is not shown in figure 1 for the sake of simplicity.
  • the covering tarpaulin 2 can be made out of one piece, or can be formed by separate strips having their side edges attached to the support beams.
  • the covering assembly 1 When the covering assembly 1 is not in use, it is rolled up in a roll-up direction which is perpendicular to the longitudinal direction of the support beams 3, which usually is the longitudinal direction of the swimming pool.
  • the roll-up direction is indicated in figure 1 by the arrow 4.
  • a storage space for storing the rolled-up tarpaulin is schematically indicated.
  • a drum for rolling up the tarpaulin 2 is present in that storage space.
  • the tarpaulin is rolled up from the opposite free end 5.
  • the covering assembly has a fixed end in or near the storage space 8, i.e.
  • the covering assembly in figure 1, it is to say that, at this fixed end, the covering assembly is permanently attached with respect to the fixed world.
  • the opposite free end 5 In order to be able to handle forces in the roll-up direction 4, the opposite free end 5 must be fastened to the swimming pool edge when the swimming pool covering assembly 1 is going to be used, and there must be a bias tension in the covering tarpaulin 2.
  • FIG. 2 schematically shows a side view of the free end 5 of the swimming pool covering assembly 1.
  • the last support beam which is indicated as end beam 13, lies entirely on the swimming pool edge 6.
  • the end beam 13 has a substantially triangular transverse contour with rounded corners.
  • One or more tightening belts 14 are attached to the end beam 13.
  • Each tightening belt 14 has a fastening bracket 15 or the like at its free end, by which that tightening belt 14 can be fastened to a fastening point 16 attached to the swimming pool edge 6 or to the floor.
  • this fastening point 16 is implemented as a hook.
  • the fastening point is countersinkable in the floor or swimming pool edge, or attached in a space countersunk in the floor or swimming pool edge, which can be covered by a removable lid, which however is not shown in figure 2 for sake of simplicity.
  • the tightening belt 14 is attached without tension to the fastening point 16, i.e. at the time of fastening there is no tension in the tightening belt 14.
  • the tightening belt 14 After the tightening belt 14 has been fastened to the fastening point 16, the tightening belt 14 must be put under tension. To that end, according to a further aspect of the present invention, one rotates the end beam 13 around its longitudinal axis, in the same direction as one would rotate the end beam 13 for rolling up the swimming pool cover in order to remove it, as indicated by the arrow P1 in figure 2. However, this rolling-up is now counteracted by the fastened tightening belt 14, which winds itself around the end beam 13 and therewith becomes taut, whereby the covering tarpaulin 2 also becomes taut, as indicated by the arrow P2 in figure 2.
  • the end beam 13 is at least at one end thereof provided with an engagement part for a power tool 50 (figures 5 and 6A-B).
  • Figure 3 schematically shows a perspective view of an end of the end beam 13, the head-end face of which is indicated with the reference number 31.
  • the engagement part 32 is implemented as a hexagonal profile, onto which an open-end wrench or the like can engage.
  • an engagement part with an internal engagement profile could also be used.
  • a tetragonal profile or an octagonal profile could be used, or a profile with even more side faces, but as the number of profile faces increases, the profile faces become smaller and the chance of damaging the profile corners is greater when exerting a great force.
  • the end beam 13 is provided with a driving shaft 33, in this case concentric with the engagement part 32, which driving shaft 33 is provided with key ways 34 on which a known per se roll-up machine can engage in order to roll up the swimming pool cover, which roll-up machine is however not shown in figure 3.
  • the end beam 13 could be provided with a tetragonal hole, and the driving shaft could be part of the roll-up machine (male/female reversal).
  • the swimming pool covering assembly further comprises coupling means 40 accomplishing a rotation-locking coupling between the end beam 13 and one of the other support beams 3, in the example shown the next support beam 3 neighbouring the end beam 13. That next end beam will hereinafter also be referred to by the phrase neighbour beam 43.
  • the figures 4A and 4B show schematic longitudinal sections of the neighbour beam 43.
  • the neighbour beam 43 is at least partly hollow, and has a head-end face 42 with a hole 41.
  • the locking means 40 comprise a telescopic locking bar accommodated in the neighbour beam 43, reaching through the hole 41 in the end face 42 of the neighbour beam 43.
  • the locking bar 44 is provided with a coupling member 45, which is suitable for coupling with the engagement part 32 of the end beam 13.
  • the coupling member 45 is implemented as a ring with an internal hexagonal profile, fitting to the hexagonal profile of the engagement part 32 of this exemplary embodiment.
  • the ring-shaped coupling member 45 is permanently attached on this end of the locking bar 44, in such a way that the centre line of the coupling ring 45 is substantially perpendicularly directed with respect to the centre line of the locking bar 44.
  • the locking bar 44 is implemented telescopically, with which is meant that the locking bar 44 contains at least two bar parts 44a and 44b fitting into each other, which can move with respect to each other in the longitudinal direction.
  • a first locking bar part 44a is at least partially hollow
  • the second locking bar part 44b is located inside the first hollow locking bar part 44a, and, if desired, can be implemented hollow or solid.
  • the two locking bar parts 44a and 44b can also rotate with respect to each other around the longitudinal axis.
  • the locking bar 44 is provided with a transverse plate 46 projecting beyond the contour of the locking bar 44, the transverse dimension of this plate 46 being larger than that of the hole 41.
  • the locking bar 44 i.e. in this case the second locking bar part 44b, is provided with a knee joint 47.
  • Figure 4A shows the locking bar 44 in a stowed-away state, wherein the locking bar 44 is located entirely inside the hollow neighbour beam 43, wherein only the coupling eye 45 projects outside the hollow neighbour beam 43.
  • the locking bar 44 is in this stowed-away state when the swimming pool covering assembly is fully rolled up.
  • the swimming pool covering assembly is used to cover the swimming pool, and has been brought under tension in the way as described before by rotating the end beam 13, the locking bar 44 is pulled out from the hollow neighbour beam 43.
  • the knee joint 47 has passed the hole 41 in the end face 42 of the hollow neighbour beam 43, the locking bar 44 can be pivoted with respect to the neighbour beam 43, as illustrated in figure 4B and in figure 5.
  • the end plate 46 prevents the locking bar 44 from being completely pulled out from the neighbour beam 43.
  • the coupling eye 45 at the end of the locking bar 44 can now be applied over the engagement part 32 of the end beam 13. In this case, the precise mutual distance between the end beam 13 and the neighbour beam 43 plays no role, because the locking bar is telescopic.
  • the open-end wrench 50 (or other tool) can be taken away from the engagement part 32.
  • the tension force in the tightening belt 14 wants to make the end beam 13 rotate, but the end beam 13 cannot rotate because then the long locking bar 44 would have to rotate along, and this is counteracted by the weight of the neighbour beam 43.
  • a transverse hole can be made through which a lock, such as a padlock or the like, can be arranged to prevent the coupling eye 45 from being pulled off the engagement part 32 at an unexpected moment by a not-anticipated force acting on the locking bar 44 from the outside.
  • a lock such as a padlock or the like
  • a swimming pool covering assembly comprising:
  • the tightening belt 14 is a loose tightening belt, which in use has to be fastened to the fastening point 16 and to the end beam 13; a disadvantage of loose tightening belts, however, is that they tend to get lost.
  • the tightening belts 14 are permanently mounted in a space sunk in the floor or swimming pool edge 6, and that, in use, they have to be fastened to the end beam 13.
  • the coupling member 45 is connected to the locking bar 44 by means of a ratchet mechanism, or that the coupling member 45 itself is provided with a ratchet mechanism.
  • the coupling member 45 can then be coupled to the engagement part 32 of the end beam 13 before the tarpaulin is tightened (force P1 in figure 2) with the tool 50.
  • the end beam 13 then has more freedom than 60° rotational positions.
  • the power tool 50 has been described as a loose open-end wrench for acting on an engagement part 32 implemented as a hexagonal profile.
  • the end beam 13 is hollow, provided with an end plate with a hole in it, and in the end beam 13 a shaft is accommodated, which is provided with a knee joint at an end, all these issues in a similar way as described with reference to the neighbour beam 43 and the locking bar 44, on the understanding that the shaft in the end beam 13 does not need to be telescopic.
  • this shaft is pulled out from the end beam, pivoted over approximately 90° by means of the knee joint in it, and then this end beam can function as lever for rotation of the end beam.
  • said shaft and the hole in the end plate of the end beam 13 can be provided with corresponding profiles, or a stop for said shaft can be arranged on that end plate.
