Abstract

The gear assembly has a casing containing two half gear wheels (4) with different diameters which mutually engage and rotate in an inverted sense. The casing can contain two gears of different diameters and they can have feet (6) on their diameters which are fixed to profiled tubes (7), the feet being identical. The half gear wheel (4) of the tube (7) of the handle (8) pivots on its vertical axis (3) and is actuated in a forward movement. It turns on its vertical axis in an inverted sense of the half wheel gear of the tube and the blade (9) which is automatically moved to the front with the blade closed.

Description

La présente invention concerne un dispositif pour articuler un aviron dans sa partie centrale, afin de créer le même mouvement aux deux extrémités.The present invention relates to a device for articulating an oar in its central part, in order to create the same movement at both ends.

Le sportif pratiquant l'aviron a, pour se déplacer sur son bateau, deux avirons d'une seule pièce chacun. En actionnant ses avirons, il a le visage vers l'arrière de son bateau et le dos vers l'avant. Le fait d'avoir cette position et de ramer le fait reculer.The rowing sportsman has, for moving on his boat, two one-piece oars each. By operating his oars, his face is towards the rear of his boat and his back is towards the front. Having this position and rowing causes it to move backwards.

Le dispositif selon l'invention permet de remédier à cet inconvénient. I1 comporte en effet, selon une première caractéristique, un boîtier dans la partie centrale de l'aviron, dans lequel se trouvent deux demi-roues dentées, sur un axe chacune et de diamètre différent et reversible, de manière à pouvoir monter la poignée de son tube des deux côtés du boîtier ainsi que la palme et son tube de manière à fournir plus ou moins d'efforts.The device according to the invention overcomes this drawback. I1 in fact comprises, according to a first characteristic, a housing in the central part of the rowing, in which there are two toothed half-wheels, on an axis each and of different and reversible diameter, so as to be able to mount the handle of its tube on both sides of the housing as well as the palm and its tube so as to provide more or less effort.

Ce dispositif permet à son utilisateur de se diriger sans être obligé de se retourner et d'être dans le sens marche de son bateau.This device allows its user to navigate without being forced to turn around and be in the running direction of his boat.

Les deux demi-roues dentées sont mises à plat sur une plaque, en ayant chacune son axe. Les parties dentées sont l'une contre l'autre et s'entraînent mutuellement :l'une tourne à gauche, l'autre à droite.The two toothed half-wheels are laid flat on a plate, each having its axis. The toothed parts are one against the other and drive each other: one turns to the left, the other to the right.

Sur les diamètres des roues dentées donnant à l'extérieur du boîtier, les demi-roues dentées sont munies de pattes plates afin de monter le tube de la palme et le tube de la poignée. Ces pattes sont identiques et peuvent recevoir les tubes de la palme ou de la poignée selon l'effort souhaité.On the diameters of the toothed wheels leading to the outside of the housing, the toothed half-wheels are provided with flat lugs in order to mount the palm tube and the handle tube. These legs are identical and can receive the tubes of the palm or the handle according to the desired effort.

Les tubes sont profilés de manière à avoir moins de résistance à l'air et à l'eau. The tubes are shaped so as to have less resistance to air and water.

La palme est montée sur son tube sur le bord d'attaque avec des charnières, elle se ferme en mouvement avant et s'ouvre en mouvement arrière sous la pression de l'eau, retenue par des tirants qui l'empêchent de s'ouvrir totalement.The palm is mounted on its tube on the leading edge with hinges, it closes in front movement and opens in rear movement under the pressure of water, retained by tie rods which prevent it from opening totally.

Les dessins annexes illlustrent l'invention:
La figure 1 représente l'invention vue de dessus
La figure 2 représente l'invention vue de face
La figure 3 représente le mouvement arrière de la palme ouverte
La figure 4 représente la poignée de son tube
La figure S représente le tube en coupe , la palme et son tirant et charnière.The accompanying drawings illustrate the invention:
Figure 1 shows the invention seen from above
FIG. 2 represents the invention seen from the front
Figure 3 shows the backward movement of the open palm
Figure 4 shows the handle of its tube
Figure S shows the sectional tube, the palm and its tie rod and hinge.

En référence à ces dessins, l'aviron comporte un boîtier 1 constitué de deux plaques 2 percées pour la fixation 5 et pour les axes 3. Entre ces plaques 2 viennent les demi-roues dentées 4.With reference to these drawings, the rowing comprises a housing 1 consisting of two plates 2 drilled for the attachment 5 and for the axes 3. Between these plates 2 come the toothed half-wheels 4.

Les demi-roues dentées 4 sont munies sur la partie du diamètre d'une patte 6 donnant sur l'extérieur du boîtier 1.The toothed half-wheels 4 are provided on the part of the diameter with a tab 6 facing the outside of the housing 1.

Sur ces pattes 6 se fixent les tubes 7. On these legs 6 are fixed the tubes 7.

Claims

1 - Device for placing an athlete practicing rowing in the direction of travel of his boat, characterized in that it comprises a housing containing two toothed half-wheels 4, of different diameter meshing one against the another by turning in the opposite direction allowing you to navigate without turning around.

2 - Device for placing a sportsman practicing rowing in the direction of travel of his boat, characterized in that it comprises a housing containing two toothed half-wheels 4, of identical diameter meshing one against the another by turning in the opposite direction allowing you to navigate without turning around.

3 - Device according to claim 1 characterized in that the toothed half-wheels 4 are provided on their diameter with tabs 6 where the profiled tubes 7 are fixed, the tabs 6 being identical.

4 - Device according to claim 1 characterized in that the toothed half-wheel 4 of the tube 7 of the handle 8, pivoting on its vertical axis 3 is actuated forward; rotates on its vertical axis 3 and in opposite direction the toothed half-wheel 4 of the tube 7 of the palm 9, which is automatically in front, the palm 9 closed.

5 - Device according to claim 3 characterized in that, pivoting on its vertical axis 3 is actuated rearward; rotates on its vertical axis 3 and in the opposite direction the toothed half-wheel 4 of the tube 7 of the palm 9.

The palm 9 opens under the pressure of the water and automatically goes back.

6 - Device according to claim 4 characterized in that in that the palm 9 fixed to the tube 7 by hinges it opens under the pressure of water, is retained by tie rods 10 preventing it from opening totally.
