Definitions

  • the invention relates to a mast for sailing vehicles with a plurality of mast sections, which are interconnected.
  • Such a mast is out DE 195 35 000 A1 known.
  • the individual mast sections are connected to each other via joints, so that the mast can be folded and transported.
  • Another two-piece sailboat mast is off DE 1 996 852 U1 known.
  • One mast part has a cone there and the other mast part has a counter cone.
  • the two mast parts are connected by that the cone is inserted into the counter cone. As a result, the mast can be made conical overall.
  • the invention has for its object to provide a mast that is suitable for sailboats with a length of at least 9 m and inexpensive to produce.
  • mast sections are formed as base sections, which have the same outer contours and are secured together twist.
  • the mast is thus formed with several identical mast sections. Preferably, even all mast sections, if appropriate, except for a section at the upper end of the mast, provided with the same outer contour.
  • These mast sections can be formed by carbon fiber reinforced plastic (CFRP). You need correspondingly short tools here. Nevertheless, you can also realize larger masts with a length of for example 12 m or more.
  • CFRP carbon fiber reinforced plastic
  • adjacent base sections are connected to each other by a respective plug-in sleeve.
  • the base sections, on the one hand, and the plug-in sleeve used for connecting two base sections, on the other hand, which can also be referred to as "adapters”, can be manufactured separately from one another.
  • the receptacle is held captive in a base portion.
  • the socket can be glued into the base section, for example.
  • the base section preferably has an insertion region in which a sleeve receptacle is arranged.
  • the sleeve receptacle which may also be referred to as an "insert", then receives the receptacle of an adjacent base portion when the two base portions are mated together.
  • the sleeve receptacle can also be manufactured independently of the base portion, which keeps the manufacturing costs low.
  • the sleeve receptacle may for example be glued or otherwise secured in the base section. It is possible to form the sleeve receptacle with an inner contour which corresponds to the outer contour of the plug-in sleeve, so that two adjacent base sections are connected to one another virtually without play.
  • each base portion has openings at predetermined equal positions. These openings can then be provided with the same during the production of the base sections, so that the production costs can be kept low again. If additional openings are required for one or the other base section, these can of course be produced. Incidentally, it is harmless if a base portion is placed at a position of the mast, where an opening would actually not be required.
  • At least one first opening is arranged on a front side and / or a rear side of the base section and at least one second opening is arranged on a lateral side of the base section.
  • the directional information refers to the later intended use, when the mast is mounted in a ship. You can then use the second opening or the second openings as Wantenauslandais, can be passed through the shrouds to stabilize the mast sideways.
  • the first openings on the front or the back can be used to pass traps or stages, for example for sails.
  • the base section preferably has a reinforced wall thickness in the region of the openings. Through an opening arises in principle first of all a weakening of the wall. This weakening can be compensated by increasing the wall thickness again.
  • the base section preferably has an inner profile with two walls running parallel to each other at least in partial areas. Such a configuration allows a simple way to realize a rotation between adjacent base portions with sufficient stability.
  • the socket can then have at least approximately a rectangular cross section, the parallel sides can be supported on the sub-areas.
  • the base portion or the panel can thus be designed so that the largest proportions for the area moment of inertia in the direction of travel and transverse to the direction of travel (when installed) are concentrated at the front and / or back in the corners, so-called "backbones". This has the advantage that holes can be provided at the front and at the sides without unduly weakening the panels.
  • the inner contour can be formed so that inside a torsion-resistant arrangement of receptacles and sleeve receptacle can be introduced.
  • the front backbones are therefore advantageously provided to form a basis for the subregions.
  • each wall has two partial areas which are arranged in the region of its front side and in the region of its rear side. This results in a very effective support against rotation of the base sections against each other.
  • a bulge is provided to the outside between at least two of the partial areas of a wall. This makes it possible to give the mast an aerodynamically favorable profile.
  • This bulge can be designed so that the mast has a cross section in the manner of an ellipse.
  • the base section preferably has a wall reinforcement on at least one partial area of at least one wall. This wall reinforcement is then where the socket acts on the base section. There is an increased mechanical stability of advantage.
  • the reinforcement can be formed by a laminate which is designed in accordance with the expected loads and has the fiber orientations suitable therefor.
  • the wall reinforcement it is preferable for the wall reinforcement to have two material layers which form a space between them.
  • This space can be filled with a filling material. But you can also use this space to form here a channel that can be used for example for a cable.
  • At least one material layer has a fiber-reinforced plastic whose reinforcing fibers run parallel to the longitudinal extension of the base section.
  • a carbon-fiber-reinforced plastic whose reinforcing fibers form a 0 ° layer. Due to this 0 ° position (based on the Longitudinal extent of the base portion), the rigidity and the area moment of inertia of the base portion for large vessels can be adjusted.
  • each base section Preferably, in each case a locking bolt is inserted through each base section.
  • later spreaders can be mounted.
  • the spreader bolt can be arranged with advantage in the region of a plug-in sleeve, which results in increased stability.
  • the base portion of the spigot has a reinforcement.
  • This reinforcement can be formed for example by the plug-in sleeve.
  • the Salingbolzen with the reinforcements thus form a kind of "knot" through which the mast is divided into short buckling lengths.
  • the stability failure is additionally stiffened about the transverse axis, whereby the dimensioning of the profile of the base portion can be easier than would be the case with a continuous, uniform profile.
  • the inclusion of the reinforcements from the connectors in the stiffness consideration and / or design of the mast against stability failure thus forms another feature of the modular rig concept.
  • the spreader pin in the interior of the base portion forms a mounting portion about which an element of the rigging is guided.
  • elements of the rigging such as shrouds or posts but also blocks for traps, provided with loops through which the spigot is inserted.
  • This riveted fittings are dispensable, which often causes the problem of corrosion.
  • Fig. 1a shows a mast 1 for a sailing ship with a length of at least 9 m.
  • the mast is formed of four base sections 2-5.
  • Each base section 2-5 is formed of carbon fiber reinforced plastic (CFRP) and has a length of about 3 meters. This results in a total height of the mast of about 12 m.
  • CFRP carbon fiber reinforced plastic
  • Fig. 1b shows a mast 1 ', which is formed from three base sections 2-4 and another section 6, the base portion 5 of the mast from Fig. 1a replaced.
  • the section 6 can taper towards the tip. It is about 1 to 1.4 m longer than the base section 5.
  • Fig. 1c shows a further mast 1 ", which in turn is formed of four base sections 2-5 and a top part 7, which can also taper upwards and may have a length of up to 3 m be put on.
  • All base sections 2-5 have the same outer contour. This outer contour results from the sectional view of Fig. 2 , which shows a schematic cross section through a base part 3.
  • the base sections 2-5 are assembled twist-proof.
  • the base sections 2-4 each have a plug-in sleeve 8, which is glued into the respective lower base section at the upper end or otherwise connected to the base section.
  • the socket 8 is inserted far enough into the base section. In many cases, it has proven to be sufficient to insert the receptacle 8 with a length of about 300 mm in the base portion.
  • the socket may have a length of, for example, 800 mm, so that about 500 mm are available to be plugged into the adjacent base section.
  • connection between the plug-in sleeve 8 and the base section 2 can also be accomplished by first securing an insert in the base section, for example by gluing, pouring or similar measures, and then connecting the plug-in sleeve 8 to the insert.
  • Fig. 2 shows a schematic section through the base portion 3 with the inserted socket 8 of the base portion.
  • the base portion 3 has a sleeve receptacle 9, which is designed as an insert and fixed in the base portion 3.
  • the sleeve receptacle is glued to the base portion 3, for example, or connected in some other way.
  • the socket 8 and the sleeve receptacle 9 are coordinated so that they interact virtually no play.
  • the plug-in sleeve 8 is "in the correct direction” and the sleeve receptacle 9 "in the correct direction”.
  • the base portion 3 has an egg or ellipse shape in cross section, this shape is not to be understood in the mathematically exact sense. However, this results in an aerodynamically favorable profile.

  • the partial regions 17, 19 are arranged in the region of the front side 10 and the partial regions 18, 20 are arranged in the region of the rear side 11.
  • the partial regions 17, 18 are preferably in one plane.
  • the partial regions 19, 20 are preferably also in one plane.
  • the left side wall 13 has a bulge 21 to the outside. This bulge 21 may be internally provided with a reinforcement 22.
  • the right side wall 14 also has a bulge 23 between the partial regions 19, 20, which may be provided with a reinforcement 24.
  • the left side wall 13 has at the portion 17 on a wall reinforcement, which is formed by the fact that two layers of material 25, 26 are provided, which form an intermediate arm 27 between them.
  • the portion 19 has a wall reinforcement with two layers of material 28, 29, which form a gap 30 between them.
  • the gaps 27, 30 may form a channel, for example, for receiving electrical lines. But you can also be filled with a filling or laminate.
  • the filling compound can be used, for example, to set the moment of inertia in the direction of travel and transverse to the direction of travel.
  • the side walls 13, 14 are simply provided with a larger wall thickness.
  • the profile of the base portion 3 described here is formed of carbon fiber reinforced plastic.
  • CFRP prepregs into a mold, close the mold and pressurize the interior 31 of the base section 3. This pressurization can be done by pressurized fluid, so a liquid or a gas, which can be used to pressurize a hose, which then adheres to the interior of the base portion 3.
  • the individual reinforcements then result from a correspondingly large number of layers of CFRP prepregs. Also by the direction of the reinforcing fibers of CFRP prepregs can be targeted Influence on the rigidity and the base sections and thus of the mast.

  • the spreader can be designed to be mutually pivotable on the spreader pin.
  • a mast which has been assembled with the aid of the described base sections 2, has a number of advantages: on the one hand, it is designed as a modular rig system in which individual parts are easily replaceable. This keeps the manufacturing costs and the stocking costs low. Since each base section 2 has only a limited length, the tooling costs can be kept small.
  • bolts such as the Salingbolzen 33, in which you can hang loops, you get a reliable mounting option for the elements of the rigging, without that you need corrosion-prone fittings.
  • the bolts can be used simultaneously for securing the base sections together, thus fulfilling a double benefit.
  • the form local reinforcements which are formed for example of a glued-sleeve receptacle or insert and receptacle or adapter, with a filled area node similar to "nodules" in the bamboo plant.
  • the mast is divided into short kink lengths.
  • the stability failure around the transverse axis is additionally stiffened. This can make the dimensioning of the profile easier.
  • the inclusion of the reinforcements from the connectors in the stiffness consideration and / or design of the mast against stability failure forms another preferred feature of the modular rig concept.
  • the standardized modular design also offers the advantage that you can adapt the base sections to different requirements without changing the outer geometry. As a rule, different area moments of inertia are required for different sizes of ships.
  • a base portion 2 as a hollow profile, such an adjustment can be achieved simply by adjusting the wall thickness, in other words, by selecting the number of layers of prepregs in connection with the configuration of the "backbones" 27, 29 as hollow chambers or as solid filled with 0 ° layers chambers. This results in an extremely high freedom of design for the formation of the individual base sections 2 or panels or for the combination of individual panels.
