Definitions

  • the present invention relates to a catamaran that can be dismantled to save space, is easy to transport and easy to assemble.
  • Catamarans are very popular with water sports enthusiasts. However, classic catamarans, like many other boats, are difficult to transport due to their size. In order to get the boat to the water, transport with a motorized vehicle or trailer is usually required. This requires the catamaran to be loaded and secured for transport. After the excursion, the catamaran must be loaded again, secured and transported back. Unless the catamaran remains permanently in the water at a pier, an excursion with the catamaran that often only lasts a few hours requires an enormous amount of time in advance and afterwards for loading, securing and transport to the mooring as well as for loading, Secure and transport back from the pier required. There is also a financial outlay for the means of transport, such as renting or maintaining a trailer/transport vehicle.
  • the catamaran must of course be stored safely even when it is not in use, which requires a suitable storage room or storage area, which requires additional financial outlay.
  • this describes DE 25 34 336 A1 dismountable catamaran and kayak hulls.
  • the hulls are split lengthwise, with the top and bottom parts being able to be tightly screwed together.
  • the upper and lower parts of two hulls can be stored one inside the other due to their slightly different sizes.
  • the catamaran does not have a reduced length due to the above-mentioned division of the hulls in the longitudinal direction, i.e., as with classic catamarans, a special means of transport is required for transport, e.g. a vehicle with a trailer. necessary.
  • the DE 33 43 662 A1 describes a sports boat with catamaran hulls that can be dismantled for transport.
  • the boat also includes various floor parts, spans, a trunk tray and a bow hood. Even if the boat described can basically be dismantled and therefore requires less space than when assembled, its space requirement is still very high, particularly due to the trunk liner, the bow hood and the fact that the hulls cannot be dismantled, so that for transporting the boat on land requires special means of transport.
  • setting up and dismantling the boat requires a time investment that will exceed the duration of a comparatively short boat trip, ie the ratio of the required effort to the actual benefit needs to be improved.
  • the DE 101 51 178 C2 describes a catamaran whose two hulls can each be dismantled into three parts, with the outer parts of each hull being able to be accommodated by its central part.
  • Each hull has the shape of a prismatic cylinder section, with the longitudinal section through each hull being a circular section.
  • Both Hulls can be connected using crossbars that are inserted into eyelets located on the hulls.
  • the AT 501 895 A4 describes a collapsible catamaran with two hull bodies and a frame connecting them. Since the two hull bodies and the frame cannot be dismantled, the catamaran requires a lot of space for storage and transport, even when folded.
  • the DE 198 11 492 A1 describes a so-called adventure boat that is built like a catamaran.
  • the adventure boat has two floating bodies that are arranged parallel to each other and form the boat hull, each consisting of two parts and connected to each other by means of two crossbars.
  • a deck extends between the two floating bodies, in which there is a recess for an observation cabin.
  • This is a transparent container that is open from above and arranged between the two floating bodies.
  • a ballast tank that can be filled with water and is preferably U-shaped is also used to ensure sufficient swimming stability.
  • the FR 1 150 577 A describes a catamaran whose two hulls are held together by various rigid struts.
  • the US 3,613,136 A describes a catamaran that can be made into the form of a trailer for transportation purposes.
  • the GB 2 213 435 A describes a multihull boat whose hulls are spaced apart by cross members.
  • the crossbars can be used for space-saving storage of the Boat folded and arranged parallel to the hulls, which can be moved towards each other.
  • the object of the present invention to provide an alternative catamaran that can be dismantled, which overcomes the aforementioned disadvantages known from the prior art and is characterized in particular by a small space requirement when disassembled.
  • the dismantled catamaran should also offer a high level of comfort in that it has a low weight, can be assembled and dismantled quickly and easily, and can be transported and/or is characterized by good driving characteristics on the water.
  • Both fuselage elements are preferably built in mirror images of one another.
  • the bow-side sub-element is connected to the rear-side sub-element via an articulated connection, in particular a hinge.
  • the bow-side sub-element and the rear-side sub-element which preferably have the same length, can be moved towards one another by means of the articulated connection in such a way that both of them come to rest on one another with one of their long sides and accordingly have a smaller space requirement in terms of length.
  • a corresponding compact storage of the sub-elements is also possible if they are not connected to one another via an articulated connection, but rather are detachably connected or to be connected, for example by entering into a positive connection, for example by being hooked into one another.
  • this connection takes place without further aids such as screws or the like.
  • the term "arrangable" means that something is or can be arranged.
  • the wording means that the at least one spacer, which can be arranged with a first end on the first fuselage element and with the opposite second end on the second fuselage element, means that the spacer can be or will be arranged between the two fuselage elements.
  • a spacer in the sense of the invention is in particular a non-elastic longitudinal element, for example a cylindrical or cuboid-shaped longitudinal element, for example made of wood.
  • a “rope” is understood to mean any type of rope.
  • the at least one spacer can be arranged with its first end in a recess in the first fuselage element and with its opposite second end in a recess in the second fuselage element, the recesses in the fuselage elements being adapted to receive one end of a spacer, for example, by having a substantially identical cross section perpendicular to their longitudinal central axis, which is minimally larger in the case of the recess as the cross section of the spacer.
  • the connection of the fuselage elements with the spacer is a plug-in connection that can be made easily, quickly and without the use of tools.
  • the catamaran according to the invention preferably has not just one spacer, but rather several, for example two, three, four or five spacers, with each of these spacers optionally being able to be arranged with its first end on the first hull element and with the opposite second end on the second hull element , in particular in recesses that are located in both fuselage elements and are each adapted to receive one end of one of the spacers.
  • the first spacer is arranged or can be arranged between the bow-side sub-elements of both hull elements and the second spacer between the stern-side sub-elements of both hull elements.
  • the catamaran according to the invention has one, two or more spacers, it is preferred that the spacers are each arranged at right angles to the two parallel-aligned hull elements on these or in recesses in them.
  • the at least one spacer or, in the case of several spacers, one of them can have an opening in which a mast can be arranged.
  • the catamaran according to the invention is suitable as a sailing catamaran.
  • the opening in the spacer is preferably arranged so that it is at the same distance from both ends of the spacer and runs perpendicular to its longitudinal central axis.
  • the stability of the catamaran according to the invention results in particular from a combination of one or more spacers and the at least two tension connections, which each run between the two hull elements.
  • tension connections are made by ropes.
  • the catamaran has at least two tension connections which run on opposite sides of the at least one spacer between the hull elements and are releasably connected to them. Both clamping connections preferably run parallel to both at right angles mutually arranged fuselage elements. One of the two tension connections therefore runs at right angles between the bow-side sub-elements of both fuselage elements, the other tension connection runs at right angles between the rear-side sub-elements of both fuselage elements.
  • the ropes or ropes forming the tension connection can, for example, be attached with their respective ends to the fuselage elements, for example by being guided around the circumference of the fuselage elements and knotted to themselves or by being knotted to hooks, eyes, pins, etc. which are arranged on the fuselage elements.
  • the catamaran according to the invention preferably has at least two further tensioning connections, one tensioning connection running between the bow-side sub-element of the first hull element and the stern-side sub-element of the second hull element and the other tensioning connection between the bow-side sub-element of the second hull element and the Rear partial element of the first fuselage element runs.
  • the two further clamping connections therefore do not run at right angles between the two fuselage elements, but at an angle other than a 90° angle. Since both further tension connections run from the front part of one sub-element to the rear part of the other sub-element, they cross between the two fuselage elements.
  • the catamaran according to the invention has a further tension connection which runs above or below the spacer, which supports the mast arranged in an opening in the spacer.
  • This additional tension connection additionally stabilizes the mast.
  • a particular advantage of the catamaran according to the invention is the shape of the two hull elements.
  • Both the two bow-side sub-elements and the two rear-side sub-elements have a cross-sectional area perpendicular to their longitudinal central axis, which corresponds to a right-angled trapezoid, the cross-sectional area of the bow-side sub-elements being perpendicular to their longitudinal central axis in a bow-side first part of each of the two bow-side sub-elements in the direction of Bugs rejuvenated.
  • the bow-side first part of the bow-side sub-elements of both hull elements extends from the bow of the catamaran by a few centimeters, for example by up to 10, up to 20 or up to 30 cm towards the stern.
  • the cross section of the partial elements perpendicular to their longitudinal central axis corresponds to a right-angled trapezium at every point, possibly with the exception of the outermost bow, which can also taper very pointedly and accordingly forms a straight line in cross section.
  • the cross-sectional area of the rectangular trapezoid in the bow-side first part of both bow-side sub-elements preferably increases continuously in the direction of the stern, up to a point from which the cross-sectional area perpendicular to the longitudinal central axis of the bow-side sub-element remains constant as the distance to the stern decreases.
  • the part of the bow-side sub-element in which the cross-sectional area perpendicular to the longitudinal central axis of the bow-side sub-element remains constant as the distance to the stern decreases, is also referred to as the second part of the bow-side sub-element.
  • the second part of the bow-side sub-element preferably has a cross section perpendicular to its longitudinal central axis, which corresponds to the cross section of the rear-side sub-element perpendicular to its longitudinal central axis.
  • the bow-side and the stern-side sub-elements of both fuselage elements can be arranged in such a way that they are arranged congruently with one end face each, while their longitudinal center axes form a straight line.
  • the two hull elements When the catamaran is assembled, the two hull elements are arranged so that the acute angle of the trapezoidal cross-sectional area of both hull elements points downward, i.e. in the opposite direction of the optional mast.
  • the side of the trapezoid which is arranged at right angles to the two adjacent parallel sides, points upwards, i.e. in the direction of the mast.
  • this side When the catamaran is lying on the water, this side is parallel to the water surface.
  • the special hull shape of the two partial hulls of a catamaran according to the invention brings about excellent driving characteristics, in particular optimal displacement of the water, and makes a keel or a centerboard unnecessary. Accordingly, a catamaran according to the invention has no keel and no centerboard, which benefits the desired low overall weight of the catamaran.
  • the catamaran according to the invention is preferably characterized by an extremely low total weight of ⁇ 60 kg. Preferably none of the individual parts weigh more than 10 kg. The catamaran is therefore particularly easy to transport due to its low weight.
  • the catamaran according to the invention can also be stored extremely compactly. Because all sub-elements of the two fuselage elements have an unchanged cross section of a rectangular trapezoid perpendicular to their longitudinal central axis at least over a large part of the length of each sub-element or over the entire length of each sub-element, the sub-elements can be arranged in such a way that two side surfaces of each sub-element are on the Side surfaces of another partial element come to rest.
  • the catamaran according to the invention preferably has a length of approximately 1.20 m, a width of approximately 0.80 m and a height of approximately 0.50 m with a space-saving arrangement of the sub-elements.
  • the catamaran is so compact that it can be transported when disassembled, for example on a bicycle trailer or in the trunk of a car. Both the space problem when storing a catamaran when it is not in use and the problem of cumbersome transport of a catamaran are solved by the present invention. But even in embodiments in which the catamaran according to the invention is larger and the sub-elements are therefore, for example, twice as long, i.e. have a length of 2.40 m, the catamaran can be stored in an extremely space-saving manner compared to catamarans known from the prior art.
  • the catamaran Regardless of the size of the catamaran according to the invention, it is advantageous that it can be quickly assembled or disassembled without the use of tools.
  • the average time it takes two people to set up a boat is less than 30 minutes, including setting up a sail.
  • the catamaran according to the invention in addition to the previously described optional mast it also has a sail, for example with a sail area of 6 m 2 .
