Definitions

  • the invention relates to a boat with a lowerable and retractable keel according to the preamble of the main claim.
  • keels with a high weight and a correspondingly large draft are used to achieve the stability that prevents capsizing.
  • the movable keel must be at least largely extended due to the necessary stability and to reduce drift.
  • Flat waters can also be sailed with a reduced sail area or under motor. Only a small water depth is required for the berths in the port.
  • Smaller yachts with a retractable keel do not need a berth in the water. They can be brought ashore using a slip and parked there. With a towing vehicle - a passenger car is sufficient for small and medium-sized yachts - even remote areas can be reached. Also coming to the bottom loses its danger, since the yacht becomes free again after catching the keel.
  • a yacht with a lifting keel is known, which is held by means of rubber ropes and can be recovered and lowered by means of a wire rope using a winch.
  • a mounting of a lifting keel is not particularly suitable, since the material of the rubber cables, particularly in the area of their fastening points, can tear due to the high load.
  • material fatigue occurs, which not only reduces the tension, but there is also the risk of tearing.
  • the invention has for its object to provide a boat with a lowerable and retractable keel, a keel with a high weight can be lowered against tensioning elements, and that the dangers due to failure of the tensioning elements are avoided.
  • the keel can be caught up by means of a spindle mounted on the cabin roof, which engages in a threaded part or the like fastened to the lifting keel.
  • the lifting keel is profiled differently in its upper area, which is guided in the lifting keel box, than on the part that can be lowered into the water.
  • the through opening provided in the bottom of the boat, through which the keel is guided, also forms a guide for the keel, which as a metallic part can be adapted very precisely to the profile of the part passed through.
  • Both the lifting keel as well as the swiveling keel and ballast sword can be provided with devices that enable locking in any position.
  • Both the lifting keel and the swiveling keel, for example, screws can be arranged at the upper end, which create a rigid connection between the keel and keel box.
  • the keel can be secured using a synthetic fiber line.
  • the line can be designed so that the line acts as a predetermined breaking point when touching the ground and allows the keel to retreat to avoid damage.
  • the sailboat shown in FIG. 1 has a lowerable and retractable keel 1 designed as a lifting keel, the upper area 2 of which is guided in a keel box 3, hereinafter referred to as the lifting keel box.
  • two compression springs 4 which serve as tensioning elements and are designed as spiral springs, run in the lifting keel box 3.
  • the cabin roof 5 ends with the Lifting keel box 3.
  • a spindle 7 runs in the center of gravity of lifting keel 1, which is rotatably and fixedly attached in the area of the cabin roof 5. At its lower end 8 it engages in the corresponding thread on the lifting keel 1. By turning the spindle 7, the lifting keel 1 can be made up or lowered into the position shown here. Details of the arrangement of the compression springs 4 and the spring channels 10 will be explained in more detail later with reference to FIGS. 4 and 5.
  • the drawing shows the lifting keel 1 completely lowered, the compression springs 4 being maximally tensioned.
  • the total force acting on the lifting keel 1 from the two compression springs 4 can correspond to the dead weight of the lifting keel 1 minus the buoyancy caused by the water.
  • the spindle 7 can thereby be easily operated by hand, for example by means of a crank attached to its upper end.
  • the spindle 7 is designed as a square 9 at its upper end.
  • the spindle 7 is supported in the area of the cabin roof 5 or in the area of the upper end of the lifting keel case 3 by ball thrust bearings.
  • the compression springs 4 are guided in the spring channels 10 provided in the lifting keel.
  • a corresponding spindle channel 11 is provided for the spindle 7.
  • the channels 10 and 11 are tubular and adapted to the diameter of the compression springs 4 and the diameter of the spindle 7.
  • the compression springs 4 can be pre-tensioned when the lifting keel 1 is completely retracted. In addition, there is the possibility of designing the compression springs 4 such that they absorb a greater force when the lifting keel 1 is completely lowered than would be required to lift the lifting keel 1. In the last area, the lifting keel 1 would have to be pressed down by means of the spindle 7 in this case.
  • the section A-B shown in FIG. 2 shows in particular the profile of the upper region 2 of the lifting keel 1 and its remaining profile 13.
  • the lifting keel box 3 has essentially a rectangular profile 14 with two rectangular bulges 15.
  • the tubular channels 10, 11 for receiving the compression springs 4 and the spindle 7 can also be seen.
  • a plurality of laterally arranged screws 16 are provided on the lifting keel box 3, with which the lifting keel can be locked in the fully lowered or any position.
  • FIG 3 a section is shown, which shows the spindle 7 and the upper end of the lifting keel 1 enlarged compared to Figure 1. At the upper end of the spindle channel 11, this has a threaded section 17, in which the spindle 7 engages.
  • FIGS. 4 and 5 show details of the arrangement of the spiral springs used as compression springs 4.
  • the lower end 32 presses against a plate-shaped stop 33 which is rigidly connected to the upper end of the lifting keel box or to the cabin roof via a rod 34 leading vertically upwards.
  • the upper end 35 of the compression springs 4 presses against a stop 36 which is rigidly connected to the lifting keel 1.
  • the stop 36 forms an upper cover of the tubular spring channels 10, while in the embodiment shown in Figure 5, the stop 36 delimits a tube 37, which forms the spring channel 10, which in a manner not shown here is connected to the lifting keel 1.
