Definitions
- the present invention relates to a catamaran type boat, that is to say comprising two hulls or floats assembled by a frame or a passenger compartment.
- the aim of the invention is to allow the realization of a boat of this type arranged so as to suppress the efforts on the connections between the hulls or floats and the frame uniting them, also allowing the floats to struggle in two planes parallel to the plane of symmetry of the ship, independently one from the other, and depending on the shape of the liquid surface, thereby obtaining better overlapping of the waves and better resistance in heavy weather.
- Another object of the invention is to provide a boat of this type arranged so that the cabin provided on the frame connecting the floats, permanently retains a horizontal position.
- the invention relates to a boat combining both qualities of good sea-keeping, speed * and stability of the passenger compartment, particularly suitable for pleasure boats, passenger transport and service (customs, coast guard, weather ship, etc ). •
- the invention is therefore embodied in a catamaran comprising two elongated floats connected together by a beam system carrying a habitacl this beam system being connected to each float by a transverse articulation oriented perpendicular to the longitudinal axis of these floats, characterized in that means constituting a differential are provided between this beam system and each float in order to maintain the axial plane of symmetry of the beam system in an average position relative to the floats.
- the differential system is of the hydraulic type and each time takes up at least one jack interposed between one end of the beam and the float conjugated at this end, the two jacks or sets of jacks provided at the two ends.
- the desired result can be obtained in particular by providing, between the beam system and the floats, double-acting cylinders whose corresponding chambers are connected together.
- the differential system is of mechanical type and it is provided between the ends of the beam system and each float one or more levers, the ends of these levers attacking the beam system being connected together, for example by a spreader, so to achieve the compensation required for maintaining the axial plane of symmetry of the beam system in the aforementioned average position.
- the differential system provided between the beam system and the floats is controlled by a gyroscope, so that the median axial plane of the beam system is kept in a vertical position.
- a gyroscope In the case of a hydraulic differential system, the desired result can be obtained by connecting the chambers of the jacks to a valve device and to a source of liquid, and by controlling this valve device and / or the source of liquid to gyroscope.
- this result can be obtained by providing in the lever system, in particular in the connecting beam associated with the beam system, a length adjusting device which is slaved to a gyroscope.
- the cockpit which forms the useful body of the boat is mounted in an articulated manner on the connecting beam system, in the middle of this system, around a horizontal axis in the plane axial of the boat, position control means being provided between this cockpit and this beam system to maintain this cockpit substantially in a vertical position, whatever the transverse tilting position of the boat and therefore the beam system.
- these means can be controlled by a gyroscopic system.
- a gyroscopic system One can see, for example, between the passenger compartment and the beam system, one or more jacks connected to a valve system and to a source of fluid, the valve system then being able to be controlled by a gyroscopic system.
- the passenger compartment is mounted on the beam system in a position such that its center of gravity is substantially perpendicular to said beam system ”Thus, the forces to be provided by the aforementioned means are relatively low. If this center of gravity of the passenger compartment is also plumb with the articulation axis of this passenger compartment on the beam system, a reduced force must also be provided by the means notably by the jack (s), serving to hold the tackle in a horizontal transverse position.
- the position of the passenger compartment is controlled longitudinally and laterally, and it remains horizontal without requiring a great expenditure of energy, whatever the movements of the sea.
- each float is constituted by a spindle of elongated shape, provided at its front end with a portion raised in the bow.
- Each time zone also carries, towards its rear end, a propeller and a rudder.
- Fig. 1 is a schematic elevation view of a catamaran type boat produced according to the invention.
- Fig. 2 is a corresponding plan view.
- Fig. 3 is a plan view similar to FIG.
- Fig. 4 is a schematic end view showing the lateral control system provided for the passenger compartment.
- Fig. 5 is a detailed view schematically indicating the mode of connection provided between the jacks of a hydraulic type differential.
- references 1 and 2 have designated the flotation elements of the boat, which are constituted by two long spindles raised at the bow-shaped front as indicated in 3. These spindles, of great length, have a tapered shape to provide on the one hand, because of their increased length, a better overlap of the waves and, on the other hand, a higher propulsion speed.
- Each spindle is equipped at its rear end with a propeller 4 and a rudder 5.
- the arrangement of the propeller drive and rudder control members has not been shown in the drawings. The determination of this provision is within the reach of those skilled in the art, who can make a direct application of the technical principles known in this field for the propulsion and steering of existing boats.
- a transverse beam designated by the reference 6 which is mounted by these ends by means of pins 7 in bearings 8 carried by the spindles.
- the axes 7 provided at the ends of the beam 6 are aligned with one another, and they are oriented perpendicular to the longitudinal plane of symmetry of the boat. These axes 7 have, as visible in the drawing, a sufficient length to maintain directional ent fu ⁇ buckets 1, 2 parallel to the longitudinal axis of the boat. They allow at the same time the movement of these fu ⁇ buckets in two vertical planes which are parallel to the axial plane of the boat. If we refer first of all to the embodiment shown in FIGS.
- these two jacks are interconnected in the manner shown diagrammatically in FIG. 5.
- conduits 12 and 13 connect together the corresponding chambers of the jacks.
- FIG. 5 of lines 14 and 15 which can be connected to a valve system associated with a source of liquid.
- a valve system associated with a source of liquid.
- FIG. 3 a mechanical type compensation system.
- One arm of each lever is attacked by a bar 18, which is connected to this lever 16 by one end by means of a hinge 19, while the other end of the bar 18 is hingedly connected in 20 to the corresponding spindle 1, 2.
- the other arms of the two return levers 16 are interconnected by a lifting beam 21.
- the palonni 21 for example a length adjusting device controlled by a gyroscope, so as to vary the length of this lifter and thus the relative positions spindles with respect to the beam 6, in order to maintain the median longitudinal plane of this beam in a vertical position "
- the catamaran according to the invention also comprises a cockpit which forms its useful body and which is shown diagrammatically at 22 in the drawings.
- this passenger compartment is mounted on the transverse beam 6 in the middle of the length of this beam, that is to say in the median longitudinal plane of the boat, by means of an axis 23 oriented along this longitudinal plane.
- This axis is oriented perpendicular to the median axial plane of the beam, that is to say that it normally occupies a horizontal position.
- the passenger compartment is placed in relation to the beam 6 so that its center of gravity is directly above this beam ”
