Abstract

The invention relates to a device making it possible to propel a craft by acting directly on the water with the aid of two paddles, the device making it possible to convert a simple oscillating movement due to the action of the user into simultaneous beating of the paddles in opposite directions. It consists of a box 1 containing three bevel gears 2 and 3. The gear 2 is secured to a shaft 4 passing through the box. This shaft is moved with an oscillating movement by means of an adaptable arm 8, this arm serving to transmit the human force. The two gears 3 are secured to two coaxial shafts 5 passing through the box 1 and to which the paddles are fixed. A rotational movement of the gear 2 drives the rotational movement, in opposite directions, of the gear 3, giving rise to the beating of the paddles. The device is connected by means of a support 7 to the craft. The support 7 has the complementary role of making it possible to change the immersion depth of the device and of changing its orientation. The device according to the invention is particularly intended for propelling craft, some of which may be designed specially for this type of propulsion.

Description

La présente invention concerne un dispositif pour propulser des embarcations,utilisant la force humaine et agissant directement sur l'eau à l'aide de palmes. The present invention relates to a device for propelling boats, using human force and acting directly on the water using fins.

Le dispositif selon l'invention permet de produire,à partir d'un mouvement d'oscillation simple d'un bras sur lequel s'exerce la force humaine,un battement alternatif et de sens opposé de deux palmes immergées. The device according to the invention makes it possible to produce, from a simple oscillation movement of an arm on which human force is exerted, an alternating and opposite direction beat of two immersed palms.

Selon une forme de réalisation préférentielle,la force humaine est transmise par un bras agissant directement sur 3'arbre d'un engrenage conique contenu dans un boitier.Cet engrenage satellite entraine à l'intérieur du boitier 2 engrenages coniques,chacun de ces engrenages planétaires étant solidaire d'un arbre.Ces 2 arbres coaxiaux traversent le boitier et supportent les palmes.L'effet de l'engrenage conique satellite et des engrenages coniques planétaires est de produire des mouvements de rotation de sens opposé des arbres coaxiaux,provoquant le battement des palmes. According to a preferred embodiment, human force is transmitted by an arm acting directly on the shaft of a bevel gear contained in a housing. This satellite gear drives inside the housing 2 bevel gears, each of these planetary gears being integral with a shaft. These 2 coaxial shafts pass through the housing and support the fins. The effect of the satellite bevel gear and the planetary bevel gears is to produce opposite rotational movements of the coaxial shafts, causing the beat palms.

Selon une variante,la force est transmise par un bras agissant directement sur l'un des arbres supportant les palmes.L'engrenage satellite,tournant librement sur un axe solidaire du boitier,a pour seul objet de transmettre la force au second arbre coaxial en l'animant d'un mouvement de rotation de sens opposé à celui solidaire du bras sur lequel s'exerce la force humaine. Alternatively, the force is transmitted by an arm acting directly on one of the shafts supporting the fins. The satellite gear, freely rotating on an axis integral with the housing, has the sole purpose of transmitting the force to the second coaxial shaft by animating it with a rotational movement in a direction opposite to that secured to the arm on which human force is exerted.

On the outside part of each of these trees (5) is fixed a palm (6). On the inside part of each a shaft (5) is fixed to a planetary bevel gear (3).

Le mouvement de rotation communiqué à l'engrenage satellite(2) provoque la rotation des engrenages planètaires(3),animant les 2 arbres(5)supportant le-s palmes(6) de mouvements de rotation de sens opposé. The rotational movement communicated to the satellite gear (2) causes the planet gears (3) to rotate, animating the 2 shafts (5) supporting the fins (6) with opposite direction rotational movements.

Le dispositif de mise en mouvement des palmes est relié par un support(7) à l'embarcation.Ce support a pour role principal de transmettre la force de poussée des palmes à l'embarcation et pour role complémentaire de permettre de régler la profondeur d'immersion du dispositif,son inclinaison et son orientation par rapport à l'axe de l'embarcation pour la diriger. The device for setting the fins in motion is connected by a support (7) to the boat. The main role of this support is to transmit the pushing force from the fins to the boat and for the complementary role of allowing the depth of the boat to be adjusted. immersion of the device, its inclination and its orientation relative to the axis of the boat to direct it.
