Definitions

  • the present invention relates to a lane divider for swimming areas, particularly for swimming pools.
  • swimming pools and particularly competition pools have a plurality of lane dividers that extend for the entire length of the pool for the purpose of thus delimiting the lanes along which the swimmers can swim without the risk of getting in each other's way.
  • dividers are removable and can also serve to separate various activities which may be taking place simultaneously in the same pool.
  • removable dividers can be used to divide a pool into different portions for the various types of activities, assigning to various swimmers those parts of the pool reserved for a given activity. They can also be used to prevent beginner swimmers from venturing into the deep end, particularly in large-sized pools.
  • the lane dividers of the prior art are generally made up of a plurality of floating elements arranged along a cable, which is usually made of steel and covered with a protective sheath.
  • floats which are generally made of a plastic material and have various shapes such as spheroidal shapes, disc-like shapes, cylindrical shapes and other shapes.
  • each lane divider The floats of each lane divider are usually in contact with each other and have a diameter approximately ranging between 5 cm and 15 cm.
  • the ends of the lane dividers are removably fastened by means of snap-hooks to anchoring devices on the sides or bottom of the swimming pool.
  • a further drawback of known lane dividers consists in the fact that because of their weight, additional buoys are often required about every 2 m.
  • a further drawback of prior-art lane dividers consists in the fact that the steel cables of the lane dividers have to be constantly kept tensioned, as swimmers lean on and hold onto the dividers and the floating discs tend to move into the central area of the steel cables.
  • a loose lane divider tends to change its position in turbulent water and under windy conditions and also not to stay afloat in the correct position.
  • a further drawback of known lane dividers consists in the fact that as the floating discs slide freely on the steel cable, two contiguous sliding discs can pinch a swimmer's skin.
  • JP 2003 340482 A discloses the technical characteristics present in the preamble of claim 1.
  • the aim of the present invention is to realize a lane divider, particularly for swimming pools, which does not need to be constantly kept tensioned or at the least requires less tensioning with respect to known dividers.
  • a further aim of the present invention is to realize a lane divider for swimming pools which prevents two contiguous floating elements from moving close to each other and thus from possibly "pinching" the skin of swimmers.
  • Another aim of the present invention is to realize a lane divider for swimming pools which limits the need to use steel cables, the ends of which could wound the skin of swimmers.
  • a further aim of the present invention is to realize a lane divider for swimming pools which is light in weight and easily removable from the water for storage on a winding storage trolley.
  • Another aim of the present invention is to realize a lane divider for swimming pools which is highly reliable, relatively simple to realize, and at competitive costs compared to the prior art.
  • a system for realizing lane dividers for swimming pools comprising modular elements, each of which having a first and a second longitudinal end and at least one seat.
  • the modular elements are mutually interconnected one after the other by respective connectors, each one comprising a shank having at least one head placed at one of its axial ends.
  • the head of each connector is also oscillatably housed in the seat of the adjacent modular element.
  • the present invention further comprises one or more of the following preferential characteristics.
  • the oscillation between the head of the connector and the seat of the modular element allows the connector to move within a solid angle.
  • said at least one seat of each modular element is positioned inside it, close to one of the longitudinal ends.
  • each modular element comprises two of said seats.
  • each connector comprises two heads placed on its respectively opposite axial ends.
  • each modular element comprises at least two half-shells interconnected to one another by means of mutually coupling members.
  • said mutually coupling members comprise at least one ring nut which is coupleable to a respective cylindrical sleeve provided in at least one of the two axial ends of the modular element.
  • the ring nut is threaded internally and can be screwed on a corresponding thread present on the outer surface of the cylindrical sleeve, or vice versa.
  • the ring nut has an inner diameter that is larger than an outer diameter of the head of the connector.
  • At least one portion of said seat is located inside the cylindrical sleeve.
  • said seat comprises a stop wall facing an axially inner surface of the head of the connector, a perimeter wall arranged around a peripheral surface of the head and a bottom wall facing an axially external surface of the head.
  • the bottom wall is convex in shape and the head is substantially flat.
  • each head of the connector has a substantially truncated-cone shape adapted to be housed in the corresponding seat of the modular element in such a manner as to enable an articulated coupling.
  • one or more of said modular elements comprises at least one floating element inside it.
  • said at least one floating element has, in a section which is perpendicular to a longitudinal geometric axis of the modular element, a polygonal perimetral profile that is for example square-shaped.
  • the modular element and the connector are made of a plastic material, preferably polycarbonate.
  • At least one of the two half-shells comprises a plurality of openings in fluid communication with the inside of the modular element.
  • said mutually coupling members comprise coupling elements integral with the half-shells and mutually coupleable by a snap fit.
  • the connector is integral with said modular element.
  • said modular elements are substantially cylindrical in shape.
  • the use of modular elements that are mutually connected by means of connectors makes it possible to avoid the use of steel cables that extend for the entire length of the divider.
  • a swimming pool lane divider that is lighter in weight and more manageable with respect to known types of lane dividers comprising a steel cable is thus made available.
  • the lane divider according to the invention indicated in its entirety by the reference number 1, comprises modular elements 10, 20, each having a first and a second longitudinal end 11a, 11b, 21a, 21b.
  • the divider 1 further comprises connectors 30, each one having a shank 31 having at least one head 32a, 32b placed at one of its axial ends.

  • the shank 31 and the heads 32a, 32b of the connector 30 also prove to be aligned along said longitudinal geometric axis.
  • each connector 30 is oscillatably housed in at least one seat 12a, 12b, 22a, 22b defined inside the adjacent modular element 10, 20.
  • an articulated coupling is realized which is capable of enabling the dividers to be wound onto a winding roller (not illustrated in the figures) when they are being removed from the water.
  • the seat 12a, 12b, 22a, 22b is positioned inside each modular element 10, 20, close to the longitudinal end 11a, 11b, 21a, 21b so as to facilitate the insertion of the head of the connector 30.
  • each modular element 10, 20 comprises, at one of the two longitudinal ends 11a, 11b, 21a, 21b, a seat for the head of the next connector, whereas at the other longitudinal end, the connector is integral with it, for example fashioned as one piece with the same modular element.
  • the connector has a shank 31 protruding outwards from the modular element and it ends with a single head adapted to be coupled oscillatably in the sole seat of the next module.
  • each modular element 10, 20 comprises two seats 12a, 12b, 22a, 22b placed at the respective axially opposite ends 11a, 11b, 21a, 21b.
  • Each connector 30 comprises two heads 32a, 32b placed on the axial ends of the shank 31.
  • Each modular element 10, 20 consists of two half-shells 10a, 10b, 20a, 20b interconnected to one another by means of mutually coupling members.
  • the mutually coupling members comprise at least one ring nut 15 which is coupleable to a cylindrical sleeve 14a, 14b provided outside of one of the two axial ends 11a, 11b, 21a, 21b of the modular element 10, 20.
  • a cylindrical sleeve 14a, 14b protrudes from each one of the two axial ends 11a, 11b, 21a, 21b of the modular element 10, 20.
  • the ring nut 15 is threaded internally and can be screwed on a corresponding thread present on the outer surface of the cylindrical sleeve 14a, 14b, or vice versa. In this manner, the ring nut mounted on the cylindrical sleeve makes it possible to keep the two half-shells 10a, 10b, 20a, 20b joined together so as to form the modular element 10, 20.
  • the ring nut 15 has an inner diameter that is larger than the outer diameter of the head 32a, 32b of the connector 30, so as to enable the passage of the head 32a, 32b and the shank 31 of the connector 30 for the insertion in the respective seat 12a, 12b, 22a, 22b.
  • the head 32a, 32b of the connector 30 is passed through the ring nut 15.
  • the head 32a, 32b of the connector 30 is then inserted in the portion of seat 12a, 12b, 22a, 22b of one of the two half-shells 10a, 10b, 20a, 20b and then the second half-shell is fitted on the first half-shell.
  • the remaining part of the head of the connector thus proves to be housed in the seat defined between the first and the second half-shell.
  • the ring nut 15 is screwed onto the cylindrical sleeve 14a, 14b, which in this manner keeps the two half-shells joined together and the head firmly inside the seat provided in the modular element.
  • At least one portion of the seat 12a, 12b, 22a, 22b is located inside the cylindrical sleeve 14a, 14b.
  • Each seat 12a, 12b, 22a, 22b has, in the area which is closest to the respective longitudinal end (11a, 11b, 21a, 21b), a stop wall 17 that faces an axially inner surface of the head 32a, 32b of the connector 30, so as to act against it when a pulling action is applied along the divider 1.
  • a bottom wall 19 is opposite the stop wall 17 and it faces an axially external end surface of the head 32a, 32b of the connector 30. The bottom wall 19 is suited to acting against the head 32a, 32b of the connector 30 when the divider is subjected to a compressing action along its own longitudinal extension.
