Definitions
- the invention relates to a device for increasing the buoyancy of a sailing board according to the preamble of claim 1.
- a generic device is known from DE-GM 83 22 936. It serves to increase the buoyancy or the stability of the sail board (or surf board) and essentially consists of inflatable tubes that surround the sail board at the edge. An air chamber can also be arranged essentially on the upper side of the sailing board. The air chambers are attached to the sailboard by means of straps or support surfaces. Devices of this type can be transported in a space-saving manner, but in connection with the sail board offer practically no additional area in order, if desired, to be able to use the sail board as a sailboat for several people or to use it as an aerodynamic wing. In addition, they are difficult to assemble.
- the invention has for its object to develop a device of the generic type so that it allows a conversion of a sailing board into a tilt-resistant watercraft for several people in a simple manner, but it can also generate buoyancy due to its shape and enables aerodynamically carried jumps with the sailing board .
- Such a device can be easily attached to a sail board because it practically only needs to be inflated after insertion of the sail board into the pocket. It then offers at least two people a sufficiently large stable and tilt-stable seating or lying surface, it also forms an aerodynamic wing and it can be transported in a space-saving manner when not inflated.
- the pocket extends from the bow to close to a sword case for a sword of the inserted sailing board and connecting means are provided on the rear part of the sailing board for fastening the mat.
- the connecting means are belts which are passed through foot straps of the sailing board. In this way, one can manage with a pocket that is vehemently short in the longitudinal direction of the sail board, in contrast to a pocket that completely accommodates the sail board. Nevertheless, the connecting means ensure that the sailing board is held securely in the bag without significantly increasing the assembly effort, since foot straps are usually present on a sailing board. If necessary, the mat rests on the foot straps and thus at a distance from the top of the sailing board. This has the advantage that the mat has little or no water contact when driving fast.
- the top view of the inflatable mat can be in the form of a delta surface with a forward swept trailing edge. This helps to reduce the flow resistance in the water.
- the delta shape of the inflatable mat is not only hydrodynamically advantageous, it also generates considerable aerodynamic buoyancy, especially near the ground. This enables higher speeds if the weight of the vehicle is increasingly carried by air instead of water. With the device in the form of a delta-shaped inflatable mat, it is also possible to make significantly more and higher jumps than previously with sail boards, because the sail board, in conjunction with the inflatable mat, acts as an aerodynamic aerofoil.
- a hose can partially run around the circumference of the inflatable mat, which has two legs that form the front profile edge of the delta surface. This facilitates the production of the mat in the form of a delta surface. Furthermore, tubes extending in the longitudinal direction of the delta surface are arranged between the legs of the tube.
- the tubes form tube chambers which are separated by webs which are cut as aerodynamic profiles, so that longitudinal cuts through the inflatable mat result in aerodynamically supporting profiles. This also creates aerodynamic lift.
- the inflatable mat can be glued or welded from airtight material. With this design, it can be easily produced in large numbers.
- the inflatable mat made of canvas or made of PVC-sewn material has chambers in which inflatable tube bodies are arranged. This results in a higher security against escape of air if the chambers are damaged by sharp edges or the like.
- the areas of the mat have upper and lower curved sections, the upper, possibly also the lower curved sections, being connected to one another by a support or covering made of flexible material. This gives the mat a smoother top and possibly also underside as well as a higher level of dimensional stability.
- the inflatable mat may have tabs or eyelets on a sailing rig.
- the sailing rig can either be braced or not.
- a holder for an oar or a motor can be provided at the rear of the inflatable mat. This facilitates control or enables mechanical drive.
- a sail board with steerable fin can be arranged in the pocket of the mat. This also makes steering easier and increases directional stability.
- the mat can have a device for releasably attaching inflatable tubes as body support or splash protection.
- the engine can also drive a propeller rotating in the air. This allows a sail board provided with the device to be driven without.
- the mat can then carry the drive and a wing of an ultralight aircraft. This enables flying as well as take-off and landing on the water with a sail board having the device (without a sailing rig).
- the sail board 1 consists of a sail board 1 and a device in the form of an inflatable mat 2 with a pocket 3 open to the rear on the front part of its underside.
- the sail board 1 is partially inserted into the pocket 3 and clamped therein by the internal pressure of the inflated mat 2.
- the width of the mat 2 is greater than that of the sailing board 1.
- the mat 2 is preferably about three times as wide as the sailing board 1.
- the pocket 3 extends from the front part of the mat 2 to the vicinity of the sword case with a foldable sword 4. The sword 4 can therefore be folded out into the pocket 3 even after the introduction of the sailing board 1.
- additional connecting means 5 can be provided in the rear part between the sailing board 1 and the mat 2.
- straps are advantageously passed through (not shown) foot straps of the sailing board 1 and wrapped around the rear part of the mat. In this way it is ensured that the unchanged rear part of the sailing board has 1 water contact.
- the mat 2 has elongated recesses 6 and 7 which coincide with its longitudinal central axis, of which the recess 6 is used to carry out a mast 8 which is adjustable in the longitudinal direction or the direction of travel and the recess 7 is used to carry the sword 4 of the sailing board 1.
- the mat 2 has the shape of a delta surface with the rear edge swept forward.
- a hose 9 runs around the circumference of the mat 2, which gives the mat the front profile edge of the delta surface. Between the legs of the hose 9 there are hoses 10 to 12 extending in the longitudinal direction, the length of which increases from the outer hoses 10 to the middle hoses 12.
- the individual hose chambers of the mat 2 are separated according to FIG. 3 by webs 13, which are cut as aerodynamic profiles, so that longitudinal cuts through the mat 2 result in aerodynamically supporting profiles.
- the mat 2 can be glued or welded from airtight material in a conventional manner, as has proven itself in air mattresses, inflatable boats or other inflatable hulls. However, it is also possible for the inflatable mat 2 to have chambers sewn from canvas or from PVC-coated material, in which (not shown) inflatable tubes are arranged.
- the mat 2 is provided with a support 14 or a covering made of flexible material, which connects the upper or possibly also the lower curved sections of the tubes of the mat 2 to one another.
- a support 14 or a covering made of flexible material which connects the upper or possibly also the lower curved sections of the tubes of the mat 2 to one another.
- tabs or eyelets 15 can be sewn on, so that the hull can be driven either with an open-ended or an un-aged sailing rig.
- the tabs are sewn on so that the heeling forces of the mast 8 are transmitted to the sailboard 1 via the pocket 3.
- a holder (not shown) for an oar or a motor 17 can be provided, as is e.g. are provided for inflatable boats. It is also advantageous if a fin 16 (FIG. 1) attached to the sailing board 1 can be steered.
- the mat 2 is advantageous to provide the mat 2 as an inflatable boat with additional inflatable hoses as body support or splash guard, which can be detachably attached.
- the hull can be driven in a conventional manner by a motor-driven propeller rotating in the water.
- the driver's seat is indicated at 21 here.
- This flying boat is able to fly in a similar way to an ultralight aircraft.
