Definitions

  • the present invention has for its object to enable the slalom to be practiced.
  • the present invention has for its object to make it an easy matter to arrange the pulleys at such distance from the pylon as to ensure complete security or, looked at from another standpoint, to allow arranging a greater number of pylons on the shore or arranging certain pylons relatively nearer to the shoe, i.e. over shallower water so as to facilitate installation.
  • a system allowing for the practice of waterskiing or ski-yorring by towing via an endless-type cable driven and guided along a closed circuit above the water by means of pulleys, and to which endless cable are fixed the conventional tow-lines, this system being characterized by the face that the pulleys are supported by pylons through the medium of non-rigid connections, that is to say through the medium of an articulated or flexible connection, equilibrium of each pulley being the result of the pull exerted by the endless cable, on the one hand, and that exerted via the articulated or exible connection.
  • the invention provides for a method of operation of a system enabling the practice of water-skiing or ski-yorring and comprising an endless-type towing cable, characterized by the fact that at least two speeds are used for the endless cable, one of which is substantially equal to the minimum speed needed to maintain buoyancy of the skier on the surface of the water.
  • FIG. 1 is a schematic plan view of the complete installation
  • FIG. 2 is an illustration showing a supporting pylon in elevation
  • FIG. 3 shows, in elevation, a supporting and tensioning ylon
  • FIG. 4 illustrates, in elevation, a supporting pylon which also provides tractive power.
  • a path of triangular shape has been chosen for the endless tow cable 1, there being two pylons 2 and 3 on the bank 4 and one pylon 5 with submerged foundations.
  • the cable is carried by pulleys 6, 7 and 8, the method of suspension of which is described with reference to FIG. 2.
  • the pulley 8 is carried by the arm 9, upon which is articulated, at 10, a cranked lever 1-1, the arm 12 of which constitutes a block for the tension roller 13.
  • This roller 13 can be adjusted by means of a screw 18 which is articulated about the arm 9 and which cooperates with a nut integral with the cranked lever 11, thus enabling the pulley 8 to be adjusted relative to the two runs of the cable 1.
  • This method of adjustment is not shown in detail, being well-known per se and of current application.
  • the bracing guys for the pylon have been designated by the numeral 19.
  • the distance between pulleys 13 and 16 will usually be relatively greater than shown in FIG. 2.
  • the pylon Z is similar to the pylon 5 except in respect to the winch 20 which serves to adjust the cable 21 and which is mounted on a counterweight 22 free to slide along vertical guides 23.
  • winch 20 By means of winch 20 the position of the counterweight 22 can be changed to accommodate changes of length of cable 1 due to temperature changes or stretching under tension.
  • This apparatus serves to tension the cable 1.
  • the pulley 7 is of the twin-groove type, one groove 25 taking the cable 1, while the other groove 26 accommodates the movement-transmitting endless cable 27.
  • the pulley is supported by the arm 28, the complete supporting arrangement being the same as that described under reference numerals 11 to 19 in FIG. 2.
  • the cable 27 passes over the pulley 30 via counterrollers 29, it being possible to interpose a speed-reduction unit (not shown) between the pulley 30 and the motor 24.
  • the rollers 29 are carried by a link 31 the end of which is slidable, say via a box-threaded sleeve screwed on to a threaded rod 32.
  • This or any other equivalent system allows adjusting the plane defined by the two runs of the cable 27 relative to the plane of the groove 26.
  • the motor is carried by the pylon 3 on a bracket 33 which is slidable along vertical guides 34. If required, the counterweight 35 may be added to contribute to tensioning of the cable 27.
  • a take-0E pontoon or raft 36 is provided, and is preferably located directly upstream of a pulley (in this instance pulley 7) relative to the direction of travel of the cable 1, as indicated by the arrow F.
  • the device is operated at two speeds at least, one of which is just suflicient to provide the necessary buoyancy for the skier on the surface of the water during the time required for the other skiers to seize hold of their respective tow-lines.
  • the normal sporting speed or speeds are the adopted.
  • speed is reduced to the connecting-up speed, to allow the skiers to relinquish hold at will, either at the nearest point to the shore or on passing in front of the pontoon.
  • an endless tow cable a plurality of pylons, open sided pulley means supported from said pylons in driving relation with said tow cable with the open side of said pulleys downward for driving and guiding said tow cable, tow lines attached to said tow cable, tensioning means associated with one of the pylons, flexible means to connect the pulleys to the pylons, whereby the equilibrium of each pulley is the result of the pull exerted by said endless tow cable tensioned by said tensioning means and of the reaction of said flexible connecting means, and a driving pulley operatively connected to one of the open sided pulleys, a pair of guide rollers mounted on the corresponding pylon, driving means vertically slidably mounted on the corresponding pylon, and an endless driving cable engaging said driving pulley and driven by said driving means, a portion of said endless driving cable being guided into a path in a plane parallel to said corresponding corresponding corresponding pylon
  • an endless tow cable a plurality of pylons open sided pulley means supported with the open side downward for driving and guiding said tow cable from said pylons in driving relation with said tow cable, tow lines attached to said tow cable, and tensioning means associated with one of the pylons and including a tensioning pulley to tension said cable, flexible means to connect the pulleys supported from the other pylons to the corresponding pylons, whereby the equilibrium of each pulley is the result of the pull exerted by said endless tow cable tensioned by said tensioning means and of the reaction of said flexible connecting means, the tensioning means for the endless cable comprising a connecting cable anchored at one extremity to the corresponding pylon, and engaging a roller on said tensioning pulley, a roller on said corresponding pylon over which said connecting cable is passed, a counterweight attached to the other extremity of said connecting cable by a winch mounted on said
  • an endless tow cable a plurality of pylons, open sided pulley means supported from said pylons arranged to form the tow cable into a polygonal course, said pulley means being in driving relation with said tow cable, the open side of said pulleys being disposed downward for driving and guiding said tow cable, tow lines attached to said tow cable, and tensioning means associated with one of the pylons and including a tensioning pulley to tension said cable, flexible means to connect the pulleys supported from the other pylons to the corresponding pylons, whereby the equilibrium of each pulley is the result of the pull exerted by said endless tow cable tensioned by said tensioning means and of the reaction of said flexible connecting means, and a driving pulley operatively connected to one of the open sided pulleys, a pair of guide rollers mounted on the corresponding pylon, driving means vertically slidably mounted on
