Definitions

  • the invention relates to keels for boats, motor or sail, these boats therefore comprising at least one submerged longitudinal element, hereinafter called “keel”, intended to ensure the boat good sailing qualities.
  • the object of the present invention is to remedy all of these drawbacks by proposing a boat comprising at least one keel the efficiency of which can vary depending on the speed of the boat, the material existence of which is subject to change (it that is to say that the keel is not constituted by a permanent and permanent structure and that therefore it may or may not ensure a role of keel depending on the circumstances).
  • the present invention also aims at a boat with at least one keel, the characteristic of which is to be substantially less fragile than a conventional keel.
  • the present invention also aims a boat with at least one keel whose characteristic is to be of a relative cost (compared to the total cost of the boat) significantly lower than that of a conventional keel.
  • the present invention also aims at a boat with at least one keel, the characteristic of which is that it is easier to assemble than that of a conventional keel.
  • the boat comprises at least one keel essentially constituted by an elongated capacity formed of a flexible, deformable and waterproof material, and it is characterized in that this keel comprises at least one opening. admission of water provided in the wall of the elongated capacity constituting it, facing the bow of the boat and kept open.
  • the water stopping pressure reigns in the keel as soon as the boat is driven in forward speed, said keel then being at least partially filled with water.
  • this water intake opening is located towards the rear part of the elongated capacity.
  • the elongated capacity is provided with at least one air discharge orifice of dimensions much smaller (in proportions of about 1 to 10) than those of the intake opening of water.
  • this air discharge orifice is situated opposite the water intake opening, that is to say that, in the case where said water intake opening is situated towards the rear of the elongated capacity, the air discharge orifice is situated towards the front of the capacity lying down.
  • the water intake opening can advantageously be arranged in the form of a scoop kept open by stiffening, at least partially, around the opening the material constituting the elongated capacity.
  • the invention consists, apart from the arrangements which have just been mentioned, in certain other arrangements, which are preferably used at the same time, and which will be more explicitly discussed below.
  • the boat shown in FIG. 1 comprises a hull 1 fitted with propulsion means 2 (constituted for example by an "in board” motor 2 a and a Z-shaped transmission 2 b ).
  • propulsion means 2 constituted for example by an "in board” motor 2 a and a Z-shaped transmission 2 b ).
  • the boat may have a flat bottom 1 a and be provided with a keel generally designated by the reference numeral 3.
  • This keel 3 is essentially constituted by an elongated capacity 4 formed from a flexible deformable and waterproof material.
  • Means are provided to make the stop pressure of the water reign in this elongated capacity 4 as soon as the boat 1 is in motion (forward) , said elongated capacity 4 then being at least partially filled with water.
  • the means 5, to make prevail in the elongated capacity 4 the water stop pressure as soon as the boat is in motion, are constituted by a water intake opening 6 formed in the wall of the elongated capacity 4, facing the bow of the boat, and kept open.
  • This water intake opening 6 is preferably located towards the rear part of the elongated capacity 4.
  • the elongated capacity 4 can be provided with at least one air discharge orifice 7 of dimensions much smaller than those of the water intake opening 6; this air evacuation orifice 7 can be arranged in the part of the elongated capacity 4 which is situated opposite the water intake opening 6.
  • the air evacuation orifice 7 is located towards the front part of the elongated capacity 4.
  • the retraction means can be of different natures and it is advantageous to have recourse to elastic means constituted by the flexible material constituting the elongated capacity 4, a flexible material which is then chosen from a material having elastic properties.
  • FIGS. 6 and 7 in which the same reference numerals designate the same members as in FIG. 2, a particular arrangement of the invention has been illustrated which allows, even when the boat is stopped, to have available 'a keel with a certain rigidity.
  • the keel of the boat has a low rigidity due solely to the gas pressure which prevails in the enclosure 8.
  • the keel has a higher rigidity, corresponding to the stopping pressure of the water which is equal to the gas pressure prevailing in the enclosure 8, said enclosure 8 therefore seeing its volume reduced to a lower value.
  • the water intake opening 6 it can advantageously be arranged in the form of a scoop kept open by stiffening, at least partially, around the opening proper 6 the material constituting the elongated capacity. 4.

Claims (8)

1. Boot mit wenigstens einem Kiel (3), der im wesentlichen durch einen langgestreckten Hohlkörper (4) aus weichem, verformbarem und wasserdichtem Material gebildet ist, dadurch gekennzeichnet, daß der Kiel (3) wenigstens eine, in der Wand des den Kiel (3) bildenden langgestreckten Hohlkörpers (4) angeordnete Wassereintrittsöffnung (6) aufweist, die zum Bug des Boots hin gerichtet ist und offengehalten ist, wodurch der Gesamtwasserdruck im Kiel herrscht, sobald das Boot mit einer Vorwärtsgeschwindigkeit angetrieben wird, wobei der Kiel dann wenigstens teilweise mit Wasser gefüllt ist.
2. Boot nach Anspruch 1, dadurch gekennzeichnet, daß die Wassereintrittsöffnung (6) im hinteren Teil des langgestrecken Hohlkörpers (4) angeordnet ist.
3. Boot nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Wassereintrittsöffnung mit rückflußverhindernden Mitteln versehen ist, die verhindern, daß das im langgestreckten Hohlkörper enthaltene Wasser durch die Schwerkraft abfließt.
4. Boot nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß der langgestreckte Hohlkörper (4) mit wenigstens einer Luftaustrittsöffnung (7) von kleineren Abmessungen als denen der Wassereintrittsöffnung versehen ist.
5. Boot nach Anspruch 4, dadurch gekennzeichnet, daß die Luftaustrittsöffnung (7) im langgestreckten Hohlkörper (4) der Wassereintrittsöffnung (6) entgegengesetzt angeordnet ist.
6. Boot nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß Retraktionsmittel vorgesehen sind, damit
― der langgestreckte Hohlkörper (4) eine ganz oder teilweise zurückgezogene Position im Boot einnimmt, wenn der Gesamtwasserdruck null oder vernachläßigbar ist, und damit
― der langgestreckte Hohlkörper (4) eine Kiels ausüben kann, wenn der Gesamtwasserdruck einen hinreichenden kritischen Wert erreicht.
7. Boot nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, daß im Inneren des langgestreckten Hohlkörpers (4) ein aufgeblähter Behälter (8) vorgesehen ist, der ein Gas eines solchen Druckes enthält, daß
― nahezu der gesamte Inhalt des langgestreckten Hohlkörpers (4) mit diesem aufgeblähten Behälter (8) ausgefüllt ist, wenn der Gesamtwasserdruck null oder vernachlässigbar ist, und daß
― nahezu der gesamte Inhalt des langgestreckten Hohlkörpers mit Wasser ausgefüllt ist, wenn der Gesamtwasserdruck einen hinreichenden kritischen Wert erreicht.
