Abstract

The apparatus consists of a buoy 1 equipped with a bottom 2 which is in part rigid, and with flippers 13, 14. Seated, squatting, or upright, the user imparts with the aid of the hands or the feet alternate impulses which control at will displacement and orientation in the manner of palmipeds. As it is possible for a number to move about, without hindrance, in swimming pools, and to collide with one another, they constitute a beneficial and engaging game.

Description

 The present invention relates to a nautical device driven by muscular pigs.

 It is intended for small trips, and more particularly for nautical games on bodies of water with limited surface area.

 The innovation lies in the simplified propulsion system allowing the easy evolution of a circular boat equipped with fins, devoid of protuberance, roughness, or hard part that can injure or deteriorate.

 The accompanying drawings show by way of nonlimiting example one of the embodiments.

 Figure 1 is a vertical section in the center.

 Figure 2 is a top plan view.

 In this version, the device consists of an inflatable buoy (1) provided with a flexible bottom.

 The boat thus formed can be used on both sides, with or without the accessories. The drawn side is the one with the bottom in the low position. If the opposite side was used, the bottom would occupy the dotted line in figure 1. The weight of the accessories and the user bends the bottom, providing a seat for the rigid part (2) whose flat upper face carries the housings (3) ( 4) (5).

Figure 1, axes of the platforms (6) (7) (8) Figure 2, swiveling.

 The central housing (3) receives the axis of the platform (6) carrying the user. The housings (4) (5), Figure 1, are intended for the axes of two small platforms (7) (8), Figure 2, receiving the feet of the user for standing use.

 Two elastic return (9) (10), Figure 1, each have their ends fixed, one on the platform (6), the other on the buoy (1).

 Two elastic return (11) (12), Figure 2, each have their ends fixed, one on each platform, the other on the bottom (2).

 Two fins (13) (14), of appropriate dimensions, shapes and flexibility, are secured in diametrically opposite positions, under the buoy, by their front parts (15) (16), Figure 2.

 They carry, slits on their curved part marrying the buoy to allow or facilitate their deployment.

 Here is a non-exhaustive description of some ways to operate this device, without, or with the various accessories.

 On the central platform, the seated or squatting user transmits horizontal pulses in one direction, then in the other, using his hands.

 The light buoy, therefore containing only a minimal inertia, compared to that concealed by the weight of the user, describes alternating rotations of measured amplitudes, causing the fins (13) (14) to travel.

 As shown in Figure 1, the palm (13) opens under the pressure of water, and works while the opposite palm (14), which is the dead time, folds under the boat, and vice versa .

 These movements executed, at will, at various speeds and amplitudes, regulate the displacement, the direction, the gyration, in the manner of palmipeds.

 The elastic bands (9) (10) absorb the jolts at the end of the stroke, and restore energy to the next pulse.

 With the elastic disconnected, the user can orient himself in any direction, regardless of the trajectory of the device.

 If the user is standing on the platform, he transmits the impulses to the buoy through apparatus such as: ski poles, guardrails, ropes, etc.

 In another way of actuating the device then provided with two small platforms (7) (8), the standing user "walks" while helping himself with the swinging of his arms, and, twists of his body to transmit to the boat, the required pulses, the elastic bands (11) (12) fulfilling their role.

 The device can also be used in a more sporty way, without platforms, feet placed on the rigid part (2). In this case the user transmits directly to the boat. the alternating, more or less accentuated rotations of his body.

 Being able to evolve in groups, without incident, on swimming pools, and, colliding, they constitute an attractive game.

 The use of this device putting 3 cofltribution most of the muscles, in particular, those solicited by the torsions of the body is very beneficial, ± t, can be of service in physiotherapy of functional rehabilitation.

 Silent, it can, provided with a suitable seat on the platform, be used by the waterfowl hunter who can instantly, with a free hand, or with the feet, orient himself to shoot.

 However, the shapes, dimensions, arrangements, number of different elements, as well as the materials used for their manufacture, may vary within the limit of equivalents, without changing the general conception of the invention which has just been described.

Claims (4)

 1) Circular nautical apparatus characterized in that a part including the user, which is heavier, imposes on the other mobile part, the lighter buoy (1), rotations of alternating directions, all the more effectively as their difference weight is important.  2) Device according to claim 1 characterized in that the boat is provided with appropriate fins (13) (14) diametrically opposite  3) Device according to claims 1 and 2 characterized in that the boat carries on a rigid central part (2) the housings (3) (4) (5) of axes of platforms (6) (7) ( 8) swiveling.  4> Device according to claims 1 2 3 characterized in that the boat is provided with tackles such as: guardrail, ski poles, ropes to transmit to the buoy the impulses of the user standing on the platform.
