Definitions
- the invention relates to watercraft, in particular sailing boats or yachts, which at the bottom one from the bottom of the watercraft down have a protruding keel to stabilize the boat.
- the movable keel is supported under load, for. B. a start, in the direction of travel, the X direction, by tilting on a front and a rear point opposite the keel shaft, the one point on the height of the ship's floor or the lower end of the keel shaft, and the other place at the top of the movable keel.
- the keel shaft must be so stable that it is able to absorb such burdens, and on the other hand must also be fully extended condition of the keel a comparatively large coverage in Extend direction between keel and keel shaft remain. So that in usually only an extendability of the keel up to a maximum of 60% of the clear height of the keel shaft reached. Nor can any deepening in the keel shaft Bridges must be installed, since the shaft remains free for the movable keel part got to.
- the properties of the boat improve with increasing Keel length, and on the other hand, with increasing keel depth, the one in the lower The area of the keel existing weight due to lead insert etc. the smaller fail, the longer the keel is, so that with extension of the keel that too Total weight of the boat drops, which is largely due to the weights in the keel is co-determined.
- Keel shaft for example the height between the bottom of the boat hull and the upper deck to achieve the greatest possible extension length
- the keel according to the invention can be as large as the ship's height with a lifting height be built and thus reaches unusual depths. This is made possible by a so-called “fixed keel”, which extends from the ship's deck to below the Longstrip is enough, and a “lifting keel” that encloses the fixed keel and on slides along this.
- the lifting and fixed keels form a rigid unit, so that only horizontal ones Support forces in the ship deck and horizontal and vertical support forces in the ship's floor must be introduced.
- lifting and Fixed keel be positively connected so that the Lifting device (spindle) is only used during the lifting and lowering process. All, even the very high forces in contact with the ground can be carried over the keel and the keel shaft into the ship's bottom. With the keel extended can a direct connection between by locking with contact pressure Lifting keel and ship's bottom can be reached, which also makes the sliding Connection between the lifting and fixed keel is relieved. By the breakdown the keel in several columns results in several parallel to each other acting sliding layers between the lifting and fixed keels and thus an inexpensive one Relationship between length and distance. Large forces can be precisely (without Game) are transmitted over a short length.
- This keel also allows an execution that is not up to the ceiling, but only up to an intermediate height, e.g. B. a table top is performed.
- the entire height, from the ship floor to the table floor, can then be as Lifting height can be used.
- Disassembly (maintenance) is carried out via a recess in the ship's deck through which the keel, after removing the outer ballast (wing keel), pulled out can be.
- the materials known in shipbuilding such as aluminum, steel, stainless steel, be used.
- the keel system is then broken down into its main parts, described and shown in the drawing.
- It consists of one or more columns arranged parallel to each other 12a, 12b, 12c, which are arranged vertically and in the inner contours of the Fit the lifting keel.
- the fixed keel 11 is attached with the upper end to the upper bearing 41 and hangs on this freely in the keel shaft 4 or sliding in the lifting keel 21.
- the fixed keel 11 ends at the bottom in the area of the ship's bottom 3, or protrudes this out what depending on the desired minimum and maximum keel depth is set.
- the lifting keel 21 is by the part of the fixed keel 11 projecting below the ship's floor.
- lifting keel 21 can be retracted as far as possible, then one is shorter fixed keel to be provided.
- the lifting keel 21 is within the keel shaft 4 through the fixed keel 11 out. A full extension of the lifting keel 21 is then not possible.
- the lifting keel 21 is guided by means of plastic slide rails 13. These are attached to the rigid corners of the fixed keel 11 and act on the equally stiff corners of the lifting keel 21, which are at the intersection of it Keel outer skin 22 with the keel webs 23 result.
- Lifting keel 21 and fixed keel 11 thus form a rigid unit that only by means of vertical and horizontal support forces are supported on the upper and lower bearings must become.
- the fixed keel 11 also serves as a lateral guide 57 for the spindle, to reduce its kink length and is used for the installation of the lock 61 utilized.
- the lifting keel 21 consists of an outer shell 22 and inner, in particular essentially vertical, from left to right continuous webs 23. Bei Smaller keels would not require webs 23.
- a sleeve 24 for supporting the lifting keel 21 on the lower bearing 31 provided.
- ballast 25 and 26 At the lower end there is ballast 25 and 26.
- ballast 26 It is mostly used as an outer ballast 26 in various forms (also torpedo-like) produced.
- the cavity 28a, 28b, 28c located inside the keel can also, up to one certain height, to be filled with ballast.
- this inner ballast 25 is only attached to the floor to create a free space to create between the ballast and the lifting keel walls for the fixed keel walls with the keel drawn in, reach to the lifting keel bottom.
- a threaded spindle 52 is also located at the lower end of the lifting keel connected.
- the lifting keel 21 is by means of fixed keel 11 and the lower bearing 31 guided, raised and lowered with the spindle 52 and over the lock 61st or the sleeve 24 connected to the ship against impacts (accident).
- Any known type of lifting device can be used. As an example described a spindle.
- the spindle 52 is on the upper bearing 41 and on the bottom of the lifting keel 21st attached. To reduce the kink length, a lateral guide 57 in Festkiel 11 are provided.
- the spindle 52 can be operated by means of a hand crank 55a or an electric motor be operated above the upper camp.
- a braking device prevents unwanted rotation of the spindle 52.
- An elastic intermediate element 55c is intended to prevent forces from entering the spindle be initiated when the lifting keel 21 by means of locking 61 with the ship connected is.
- a cladding tube 53 in the lower area and a bellows 54 in the upper area protect the Spindle in front of sea water.
- the spindle 52 is only in the keel position during the lifting process the lock, actively loaded.
- the lock 61 enables one in any position (recess 27) direct, in particular positive connection between lifting keel 21 and Fixed keel 11 and in the extended position a connection between lifting keel 21 and ship floor 3.
- the latch 61 consists of a mechanical device that is operated manually or operated mechanically (hydraulic, electrical) and thereby a round or wedge-shaped bolt 62, which is arranged in the fixed wedge 11, in therefor provided recesses 27 of the lifting keel 21 drives.
- the lock 61 is attached within the fixed keel 11.
- the bolt 62 is by means of a two-armed Angle lever 63 operated manually from the upper bearing 41 with a rod 64.
- the uppermost recess 27 in the lifting keel 21 is made so that the underside Bevel of the bolt 62 the edge of the lifting keel (sleeve 24) to the lower bearing 31 of the Presses ship floor.
- the lower bearing 31 is formed on the ship's floor 3, in particular in one piece. It is divided into a horizontal surface 32 for vertical forces and one vertical surface 33 and 34 for horizontal forces.
- the horizontal surface 32 is part of the loadbearing floor 3, which in the Keel shaft 4 protrudes like a lug, and an elastic pad.
- the vertical surface consists of a vertical edge of the ship floor 34, supplemented with an elastic 4-point keel support (Fig. 8a), the one elastic sliding layer 33 comprises.
- the horizontal bearing surface 32 prevents one The lifting keel 21 falls out.
- the elastic 4-point support of the vertical bearing surface 33 holds the outer one Surface of the lifting keel 21 free from contact with the ship's bottom 3. This protects the antifouling paint.
- the front and rear of the lifting keel 21 rests rigidly on the vertical bearing 34, since the elastic layer, which previously ensured the distance, pressed together becomes.
- the upper bearing 41 is formed by a false ceiling 42 or 43, which is supported on the keel shaft.
- the camp takes everyone horizontal and vertical support forces of the fixed keel part 11 and the spindle 52 on. It can also serve as a control panel for the drive elements 55 Serve spindle and lock 61.
- the keel shaft 4 envelops all parts of the keel and covers the opening in the ship's floor 3. It consists of a hollow column that extends from the ship's floor 3 to to the ceiling 2 or only up to the table top 42.
- It has a rectangular 4a or oval cross section adapted to the shape of the keel 4b.
