    The invention relates to a device for rowing in the viewing direction with a handle lever and a distance from the handle lever mounted rudder, which is connected to the handle lever via a coupling in the manner of an opposing four-bar linkage, and with a Anlenklager for the rudder and the handle lever receiving , via the handle lever about a pivot axis extending substantially in the direction of travel pivoting rocker.
    For rowing in the direction of view, a handle lever separated from the rudder is used, which is in a drive connection with the rudder, which allows a reversal of motion, so that the rudder blades are displaced forward in a return movement into the delivery in the event of a travel in the direction of travel. For this purpose, it is known to connect the spaced apart from the handle lever on a rocker rudder with the handle lever via a coupling in the manner of an opposing four-bar linkage. The storage of the handle lever and the rudder on a rocker, which is mounted ver-pivotable about an axis extending in the direction of travel, is necessary to ensure the immersion of the rudder blades into the water and their extraction from the water when the handle lever from the display for the Draft lifted and lowered again at the end of the train. A twisting of the rudder blades at the end of the train to return the rudders near the water surface in the display and then rewind for the train is possible, but only with a disproportionate design effort.
    The invention is therefore based on the object, a device for rowing in the line of sight of the type described in such a way that with relatively simple constructive measures up and turning the rudder blades is possible. 2
    The invention solves this problem by the fact that the rudder comprises a rotatably mounted about its axis in a bearing body rudder rod, via which the rudder is articulated to the rocker and connected to the coupling of the four-bar linkage, and that on the rudder rod a rotary drive with a in the Bearing body slidably guided actuator attacks, which is supported on a pivot axis forming the rocker carrier.
    By the rotatable mounting of the rudder blade-bearing rudder rod about its axis, a simple condition for the up and turning of the rudder blade is first created. It therefore only requires a corresponding rotary drive for the rudder rod as a function of the rudder movement. This determined by the altitude of the handle lever dependency makes use of the invention, by the pivotal movement of the handle lever and the rudder receiving rocker is used with respect to the supporting carrier for the rotary drive.
    For this purpose, the rotary drive is provided with a slidably guided in the bearing body for the rudder rod actuator, which is supported on the support for the rocker and therefore does not join the pivotal movement of the rocker, so that the displacement of the actuator relative to the bearing body for the rotary drive of the rudder rod be utilized can. Accordingly, if the handle lever is lowered and thus pulled the rudder blade due to the pivotal movement of the rocker out of the water, the supported on the carrier actuator is advanced against the bearing body and rotated the rudder rod in the sense of twisting off the rudder blade on the rotary drive. When lifting the handle lever is reversed because of the opposite direction of pivoting movement of the rocker and the direction of displacement of the actuator relative to the bearing body with the effect that the rudder blade is turned on again for the passage.
    Thus, the system of the actuator on the support for the rocker can be ensured at least during the decisive for the blade rotation pivotal movement of the rocker, the actuator can be acted upon in the sense of a system on the carrier with a return spring. In addition, since the rotational positions of the rudder blades 3 are predetermined for the up and turning, the rudder rod between two rotational stops in the bearing body can be rotatably mounted, whereby the two rotational positions of the rudder blade are determined constructively.
    In order to derive a rotational movement for the rudder rod from the adjusting movement of the bearing member displaceably mounted in the bearing member for the rudder rod, the rotary drive for the rudder rod from a rack and pinion drive with a formed by the actuator, mesh with a ring gear of the rudder rack. If the rocker pivoted via the hand lever relative to the carrier receiving the rocker and thus moved the actuator relative to the bearing body, so requires the sliding movement of the rack a corresponding rotation of the rudder rod relative to the bearing body and thus a change in the rotational position of the rudder blade. Another way to implement the sliding movement of the actuator in a rotational movement of the rudder rod, results when the rotary drive for the rudder rod provided between the bearing body and the rudder rod knee lever drive, the knee joint is supported via a tab on the actuator. About the tab thus the toggle lever drive is applied, which ensures due to its articulation on the rudder rod for the respective rotational movement of the rudder blade. Because of the resulting by the toggle lever gear ratio advantageous design conditions are present, especially since the crowded space, the crowded space in the region of the bearing body and its Anlenklagers can be advantageously used.
    The swing angle of the rocker relative to its carrier is limited in one direction by the carrier itself, but not in the opposite sense of pivoting. So that the rudder bars can not be lowered arbitrarily far into the water, it is therefore recommended to limit the swing angle of the rocker. For this purpose, a limiting cylinder can advantageously be articulated between the rocker and the carrier, via which a damped stop can be ensured. 4
    In the drawing, the subject invention is shown, for example. Show it

    Fig. 8 shows a section along the line VIII-VIII of FIG. 6 on a larger scale and
    9 is a representation corresponding to FIG. 8 of a design variant of a rotary drive.
    When rowing in the direction of view, it is necessary that the rudder 1 is moved in opposite directions to the handle lever 2, with which the rudder t is operated. In Fig. 3, the movement of the handle lever 2 is indicated with the associated rudder positions during a passage. The rowboat itself, which has two hulls 3, which is not required by any means, is conventionally equipped with a rolling seat 4 and a footrest 5, so that the handle levers 2 can be handled as usual in the skull, but viewed in the direction of travel 6. About a reverse gear 7, the handle lever 2 is connected to the rudder 1, so that in the dashed lined display of the handle lever 2, the rudder 1 is pivoted in the direction of travel 6 forward against the bow and moves during the passage to the rear against the rear. The Zugende the rudder 1 is indicated by dash-dotted lines. 5
    In Fig. 4, the reverse gear 7 between the handle lever 2 and the rudder 1 is shown in more detail. The Anlenklager for the rudder 1 and the handle lever 2 are denoted by 8 and 9 and determine the basis for an opposing four-bar linkage, the coupling 10 connects the handle lever 2 with the rudder 1. Accordingly, if the handle lever 2 is pivoted clockwise in the Anlenklager 9, the rudder 1 is rotated counterclockwise in Anleklager 8.
    The rudder blade 11 should be rotated at the end of the train when pulling out of the water in the shown in Fig. 1 wacky rotational position to be pivoted in the extended position again in the unfolded position of FIG. From FIGS. 1 and 2 it can be seen that the respective sheet position depends on the pivot position of the rudder 1 with respect to a pivot axis extending in the direction of travel 6. To enable this necessary for the rudder pivoting of the rudder 1, the Anlenklager 8 and 9 are provided for the rudder 1 and the handle lever 2 shown in FIGS. 4 to 6 on a rocker 12, which extends about an approximately in the direction of travel 6 pivot axis 13th is mounted pivotably on a support 14. The carrier 14 can be clamped by means of clamping screws 15 to a dash-dotted line longitudinal spar 16 of the hulls 3. Therefore, the rocker 12 can be pivoted relative to the carrier 14 via the handle lever 2 in order to pull the rudder 1 out of the water or to dive into it.
    Thus, when lifting and lowering the handle lever 2 as shown in FIGS. 1 and 2, the rudder blade 11 accordingly turned off and on, the rudder rod 17 is rotatably supported about its axis in a bearing body 18 which is rotatably mounted in the Anlenklager 8 and on the the coupling 10 of the reverse gear 7 attacks. The bearing body 18 forms a guide 19 for an actuator 20 of a rotary drive 21, which rotates the rudder rod 17 in response to the pivotal position of the rocker 12. For this purpose, the actuator 20 is supported on a stop 22 of the carrier 14 and is pressed by means of a return spring 23 against this stop 22. Thus, if the handle lever 2 is lowered from the position for the passage of FIG. 2 in the position for retrieving the rudder 1 of FIG. 1, 6, the actuator 20 abuts the stop 22 of the carrier 14 and is shown in FIG. 5 and 7 advanced in the bearing body 18. About this travel the rotary actuator 21 can be operated.
    According to FIGS. 7 and 8, the rotary drive 21 comprises a toggle lever drive 24 hinged on the one hand to the bearing body 18 and on the other hand to the rudder rod 17, the knee joint 25 of which is connected to the actuator 20 via a lug 26. When lowering * the handle lever 2 and the associated lifting of the rudder blades 11 thus the knee joint 25 is bent over the actuator 20 upwards, resulting in a corresponding rotation of the rudder rod 17 with the result after that the rudder blades 11 in the position Fig. 1 are turned off. When lifting the handle lever 2, the actuator 20 via the return spring 23 * sensibly acted upon with the effect that the rudder rod 17 is rotated back over the rotary drive 21 in the position for the untwisted rudder blade 11. At least in this unfolded rotational position of the rudder blades 11, the rudder bars 17 are to be supported against rotation, so that the rudder blades 11 can not avoid the water pressure. For this purpose, a corresponding stop 27 is provided for the rudder rod 17, as shown in FIG. 8 can be removed.
    In contrast to the rotary drive 21 of FIGS. 7 and 8, the rotary drive 21 according to FIG. 9 has a rack drive, in which the actuator 20 forms the rack 28, which cooperates with a ring gear 29 of the rudder rod 17. Also in this case, the rotational movement of the rudder rod 17 and thus the rudder blade 11 in response to the displacement of the actuator 20th
    In order to prevent a deeper lowering of the rudder 1, a swing limit can be provided for the rocker 12. In the case of the illustrated embodiment, this pivot limiting is formed by a limiting cylinder 30 which is articulated between the rocker 12 and the carrier 14.
