Definitions

  • ABSTRACT A device for separating the lanes in a swimming pool for swimming race and comprising a cable carrying floats shaped as solids of revolution having a hub provided with an axial through-going hole for the cable and with a concave spherical support surface at one end and a convex spherical support surface at the 0pposite end, the middle portion of said hub being connected to a surrounding water breaking peripheral portion having a smaller axial extent than the hub.
  • the invention relates to a device for separating the lanes in a swimming pool for swimming race and comprising a plurality of floats carried by a through-going cable.
  • the swimming pools are usually divided into lanes separated by cables carried by mutually spaced floats.
  • the waves produced by a swimmer in one lane are propagated to the adjacent lanes disturbing the swimmers in these.
  • a device comprising floats formed as bodies of revolution having a hub provided with an axial through-going hole for the cable and with a concave spherical support surface at one end and a convex spherical support surface at the other end, the middle portion said hub being connected to a surrounding wave-breaking peripheral portion having a smaller extend in the axial direction than said hub.
  • the floats which are arranged closely side by side, are mutually pivotable in such a manner that they are forming a flexible bar, which, however, has retained its cable-like characteristics and consequently is easy to handle and the wave-shaped peripheral portions combined with the through-going bar formed by the hubs bring about that the waves produced by the swimmers preclude that the waves can be propagated to the adjacent lanes or under all circumstances they are dampened considerably in the small channels formed between the bodies.
  • the mutual flexibility between the separate floats and the flexibility of the cable as a whole is considerably increased when the throughgoing holes for the cable at their ends are provided with funnel-shaped or conical mouth portions.
  • peripheral portions in the axial direction allows a substantial bending of the cable before the peripheral portions are abutting each other and according to the invention said portions may suitably be tore-shaped, whereby their influence on the waves are the same whatever the direction of the waves towards the cable may be.
  • the device can be produced with a relatively small weight for instance the floats may be made of plast material and may have a hollow hub and/or peripheral portion.
  • the whole row of floats may be held together by the uttermost floats being abutting correspondingly domed metal-discs the outer surfaces of which are limited by retaining members serving to secure the cable to lock-bolts, each of said bolts being provided with a head being so formed and connected to the remaining portion of the bolt that it can be inserted through a key hole-shaped opening in a furnishing on the end-wall of the swimming pool and can be retained therein.
  • FIG. 1 shows an embodiment of the inventive device
  • FIG. 2 is an axial view through two abutting floats
  • F IG. 3 a view corresponding to that of FIG. 2, but with the floats being slightly pivoted relative to one another in such a manner that they no longer are coaxial.
  • the inventive device comprises a cable 1 upon which is suspended a rope of closely arranged floats 2 formed as bodies of revolution and moreover, being shaped as best seen in FIGS. 2 and 3.
  • each float has a substantially sperical, hollow hub 3, which at their ends are provided with spherical support surfaces i.e. at one end with a conical support surface 4 and at the other end with a convex support surface 5.
  • the cable 1 is passed through a through-going axial hole 6 in each float 2, which holes at their ends are funnel-shaped entlarged portions 7 and 8 which are increasing the ability of the floats to turn in axial planes.
  • the floats are free to rotate in radial planes about the cable 1 overcoming the friction between the support surfaces so that they can rotate when influenced by the waves and at the same time as they are exposed to a braking and wave-dampening or wave-calming force.
  • the arriving waves are broken against a hollow peripheral portion 9 which is connected to the middle portion of the hub 2 through a flat annular portion 10. It will be seen that the peripheral portion 9 has a smaller extent in the axial direction than the hub 2 so that they are no hinderance to the bending of the cable such as appears from FIG. 3.
  • the waves are forced through the channels through the floats in which they are divided and dampened.
  • the uttermost floats 2 are abutting correspondingly domed metal-discs 11, the displacement of which towards the end of the cable are limited by retaining members 12.
  • the retaining member 12 is securing the cable to a lock-bolt 13 provided with a head 14 which can be inserted in a key hole-shaped opening in a mounting (not shown) in the end-wall of the swimming pool and can be retained therein as the edges of the narrow portion of the key hole are engaging the grooves 15 in the lockbolt.
  • a turnbuckle 16 Between the retaining member 12 at the right end of the cable in FIG. 1 and a lock-bolt 13 not shown is inserted a turnbuckle 16.
  • the floats need not be hollow plastic bodies, but they can be solid bodies made of a material with a small specific weight.
  • a device for separating the lanes in a swimming pool for swimming race comprising a plurality of floats being suspended from a through-going cable, characterized in said floats being bodies of revolution provided with a substantially spherical hub having an axially through-going hole for the cable and a concave spherical support surface at one end and a convex spherical support surface at the other end, said hub at its middle portion being connected to a surrounding wave-breaking peripheral portion the axial extent of which is less than that of the hub, said peripheral portion being tore-shaped and being connected to said hub through a flat annular portion.
  • each of said lock bolts having a head being so shaped and connected to the remaining part of the respective lock-bolt that it can be inserted through and retained in a key hole-shaped opening in a mounting on the end-wall of the swimming pool.
