Abstract

The subject of the invention relates to a nautical appliance with inflatable float. It is constituted by the combination, on the one hand of the drive transmission with sealed shaft, and on the other hand the steering gear for controlling the rudder 28 with the arm connected to the rudder bar and likewise sealed connection rod, and finally by the functional profile of the pneumatic float with pointed stem. It is intended to constitute a small craft to be used for providing aquatic instruction for children, with vibration-damping peripheral pneumatic protection from collision, as well as a small craft to be used for pleasure on calm water surfaces (lakes, ponds, the sea, swimming pools, etc) after adding a second sealed compartment onto the float in accordance with standards in force.

Description

 The object of the invention relates to a nautical device with an inflatable float.

 It is intended to constitute a boat for the use of an aquatic merry-go-round for children, with peripheral pneumatic protection, buffering shock absorber as well as a boat for the use of a ride on calm water (lakes, ponds, ponds, swimming pools, etc.) addition of a second waterproof compartment on the float corresponding to the standards in force.

 I1 is known of such merry-go-round devices, but the means of transmission of propeller power, steering and also of protection presented multiple maneuvers with regard to the controls, handling, safety and propulsion speed, and especially the tightness of the transmissions.

 The device according to the invention eliminates these drawbacks and makes it possible to produce a light boat, perfectly balanced and protected with a float profile facilitating the advance and protection, but above all with a simplified transmission and a gourvernail with improved control.

 It is made up of the combination, on the one hand of the drive transmission with sealed shaft, and on the other hand the steering linkage of the rudder with arm connected to the lifter and traction rod also sealed, and finally by the functional profile of the float pneumatic with pointed bow.

In the appended drawings given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows seen in elevation and in longitudinal section the boat as a whole.

 Figures 2 and 3 show the constructive detail of the wheelhouses of the gourvernail and the power transmission to the propeller.

 Figures 4 and 5 are elevational and plan views of the boat.

 The boat, FIGS. 1, 2, 3, 4, is constituted by a hull 1 and an inflatable peripheral float with prow 3 shaped in a point.

 The transmission of the driving force from the engine 4 to the propeller 5 is effected by a shaft 6 with a clutch element 7 by notching of the "balonnette" type connecting it by translation with the counterpart 8.

 This contact clutch element is keyed onto the shaft 9 secured to the propeller 5.

 Sector 9 of the drive shaft is concentric with a cylindrical casing 10 bearing bearings 11, 12 with double conical seals 13, 14, 15, 16. Ball bearings 17, 18 complete this assembly. There is therefore a total seal and at each of the immersed ends 19 or at the bottom of the shell 20, FIGS. 1, 3.

 The steering, Figures 1, 2 is constituted by a flywheel 21 is transmitted by the vertical shaft 22 and the stirrup 23, with transmission arm 24 to the spreader 25. This spreader tows in the front and rear directions, arrows A and B , the rod 26 which by the stirrup 27 varies the position of the rudder 28 by rotation around the fixed point 29.

 The amplitude of this swiveling around the fixed point 29 is maximum and corresponds to the amplification of the translation A B. The rod 26 slides in a protective casing 30 provided with cable glands or sealing points at each of its ends 31, 32 immersed or at the bottom of the hull.

 The buoyancy of the machine and its maneuverability are improved and its direct transmission with contact clutch give this boat maximum useful effect.

 However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, as moreover the materials used for their manufacture, without thereby changing the general design of the invention which has just been described.

Claims (2)

 10 Nautical craft device with inflatable float designed to create an aquatic ride for children with peripheral pneumatic protection, shock absorber and stabilizer, as well as a boat for use on a ride on calm water (lakes, ponds, ponds, swimming pools etc ...) after adding a second sealed compartment on the float to the standards in force, characterized by the combination on the one hand of the drive transmission with motor (4) shaft (6), clutch element by contact and notching (7, 8)) connected to the shaft (9) driving the propeller (5) and sealed by a double O-ring (13, 14, 15, 16), on the other hand by the wheelhouse of the rudder constituted by a flywheel (21) integral with the vertical shaft (22) of the stirrup (23), of the transmission arm (24) connected by articulation to the lifter (25) effecting front or rear traction on the rod (26 ) connected to the rudder (28) and concentric with the sealing casing (30) provided that the float inflates ble (2) comprises a bow (3) shaped as a point.  20 Device according to claim 1, characterized in that the sealing casing (10) in the axis of which the concentric motor shaft (9) rotates comprises a seal (11) with double O-rings (13, 14) and (15, 16) as well as a ball bearing (17,18).  3) Device according to claim 1 characterized in that the transmission shaft or rod (26) connecting the lifter (25) to the rudder (28) with transmission stirrup (27) integral with the rudder (28) swiveling around its fixed point (29) is concentric in its sector of exit from the hull to a cylindrical protective casing (30) with seals (31,32) at each of its immersed ends or at the bottom of the hull.
