Said connection devices may also be arranged inside the boat hull. The linear guiding (11) is substantially comprised of a shaft (12) extending in parallel to the longitudinal axis of the boat inside or outside the hull (11a). On said axis (12) are guided by sliding and/or rolling one or a plurality of suspension elements (13) connected to one or a plurality of outriggers (1).

Description

Die Erfindung betrifft ein Ruderboot mit wenigstens einem bootsfesten Rudersitz und diesem zugeordneten, in Bootslängsrichtung verschiebbaren Gleitausleger mit damit bewegungsstarr gekoppeltem Stemmbrett.The invention relates to a rowing boat with at least one rudder seat fixed to the boat and associated with it, which can be moved in the longitudinal direction of the boat, with a rigidly coupled stretcher board.

Ein derartiges Ruderboot ist aus der britischen Patentschrift 607158 bekannt. Dort ist die Einheit aus Auslegern und Stemmbrettern in insgesamt drei Linearführungen geführt, von denen zwei seitlich und eine weitere unterhalb der Stemmbretter angeordnet sind. Derartige Führungen kann man nicht mit ausreichend genauer Parallelität herstellen. Beim Rudern kommt es daher zu erheblichen Reibungsverlusten in den Führungen bzw. die Gleitausleger verklemmen zwischen den Führungen.Such a rowing boat is known from British Patent 607158. There the unit consisting of brackets and stretcher boards is guided in a total of three linear guides, two of which are arranged on the side and another below the stretcher boards. Such guides cannot be produced with sufficiently precise parallelism. When rowing, there is therefore considerable friction loss in the guides or the sliding boom jams between the guides.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, das gattungsgemässe Ruderboot so auszubilden, dass es sich für alle Typen von Ruderbooten einschliesslich mehrrümpfiger Boote leicht rudern lässt und die Gefahr des Verkantens oder Verklemmens der Gleitausleger ausgeschaltet ist.In contrast, the invention has for its object to design the generic rowing boat so that it is easy to row for all types of rowing boats including multi-hulled boats and the risk of jamming or jamming of the sliding boom is eliminated.

Diese Ausgabe wird mit den im Anspruch 1 gekennzeichneten Merkmalen gelöst. Demnach wird die lineare Längsbewegung des Gleitauslegers von einer einzigen Linearführung, z. B. einer Schiene, über beispielsweise kugel- oder gleitlagergeführte Elemente, Rollen oder dgl. präzise geführt. Da bei dem hier angewandten Prinzip des linear geführten Schlittens das seitliche Führungsspiel minimal ist, ist erfindungsgemäss die Gefahr der Verkantung praktisch ausgeschlossen. Bereits dadurch wird ein gleichmässiger Bewegungsablauf beim einzelnen Ruderer unterstützt.This issue is solved with the features characterized in claim 1. Accordingly, the linear longitudinal movement of the sliding arm of a single linear guide, for. B. a rail, for example, guided by ball or slide bearing elements, rollers or the like. Precisely. Since the lateral guide play is minimal in the principle of the linearly guided slide used here, the risk of canting is practically excluded according to the invention. This alone supports an even movement of the individual rower.

Gemäss einer weiteren Ausgestaltung mit wenigstens zwei gekoppelten Gleitauslegern oder auch mit ein oder mehreren Gruppen von Gleitauslegern innerhalb eines Bootes genügt es, wenn ein derartiger Gesamtausleger wenigstens an beiden Enden an der Linearführung gelagert ist. Neben einer Verbilligung der Konstruktion ist damit auch eine Gewichtsreduzierung erzielbar.According to a further embodiment with at least two coupled sliding arms or also with one or more groups of sliding arms within a boat, it is sufficient if such a total arm is mounted on the linear guide at least at both ends. In addition to making the construction cheaper, a weight reduction can also be achieved.

Die beim Gesamtausleger die Bewegungskopplung realisierenden Verbindungseinrichtungen können im Rahmen der Erfindung leicht lösbar ausgeführt sein. Durch die Bewegungskopplung wird die Einstellung der einzelnen Ruderer auf den Mannschaftsrhythmus wesentlich erleichtert. Die Verbindungseinrichtung kann dabei entweder zwischen ausserbordigen Abschnitten der Gleitausleger und/oder innerhalb des Bootsrumpfes angeordnet sein.The connection devices that implement the motion coupling in the overall boom can be designed to be easily detachable within the scope of the invention. The coupling of movements makes the adjustment of the individual rowers to the team rhythm much easier. The connecting device can either be arranged between extra-large sections of the sliding boom and / or within the boat hull.

Dabei kann es besonders bei mehrrümpfigen Ruderbooten, aber auch bei Ruderbooten mit zweireihiger Sitzplatzanordnung zweckmässig sein, die Gleitausleger mehrerer Reihen oder auch von Sitzgruppen verschiedener Reihen miteinander zu koppeln. Die Linearführung wird zweckmässig als eine zur Bootslängsachse parallel verlaufende Welle oder Schiene realisiert, die innerhalb oder ausserhalb des Bootsrumpfes angeordnet ist. Dabei sind längs der Welle oder Schiene rollend oder gleitend gelagerte Aufhängungselemente geführt, woran die Gleitausleger befestigt oder aufgehängt sind. Statt mit geschlossenen Lagern-Kugelbüchsen oder Gleitbuchsen-kann die lineare Führung auch mit Stützrollen bewerkstelligt werden. Diese sind in einem das Schienenprofil der Linearführung umschliessenden Käfig derart angeordnet, dass sie wenigstens alle horizontalen Kräfte aufnehmen können, die über den Ausleger und den Käfig auf die Linearführung einwirken. Führungsspiel und Reibungsverlustewerden dabei weitgehend vermieden, da die einzige Linearführung die Verwindungen des Ruderboots beim Rudern nicht mitmacht.It can be particularly useful in multi-hulled rowing boats, but also in rowing boats with a two-row seat arrangement, to couple the sliding arms of several rows or of seating groups of different rows with each other. The linear guide is expediently implemented as a shaft or rail which runs parallel to the longitudinal axis of the boat and is arranged inside or outside the hull. In this case, suspension elements are mounted in a rolling or sliding manner along the shaft or rail, to which the sliding arms are attached or suspended. Instead of using closed bearings - ball bushings or sliding bushes - the linear guidance can also be achieved with support rollers. These are arranged in a cage enclosing the rail profile of the linear guide in such a way that they can absorb at least all horizontal forces which act on the linear guide via the cantilever and the cage. Guide play and friction losses are largely avoided, since the only linear guide does not take the twists of the rowing boat into account when rowing.

Für einen ordnungsgemässen Ruderbetrieb ist es erforderlich, dass die Gleitauslegerbewegungen stets in einer im wesentlichen horizontalen Ebene ablaufen. Nach einer weiteren Ausgestaltung wird dies - bei gleichzeitiger Entlastung und Vereinfachung der Linearführung - verwirklicht, dass seitlich am Aufhängungselement Stützrollen zur vertikalen Abstützung des Gleitauslegers angebracht sind. Andererseits ist es auch möglich, dass die vertikale Abstützung der Gleitausleger entweder von der Linearführung oder von den Stemmbrettern übernommen wird. Letztere sind dazu zweckmässigerweise mit Stützrollen ausgestattet.For proper rowing, it is necessary that the sliding boom movements always take place in a substantially horizontal plane. According to a further embodiment, this is achieved - with simultaneous relief and simplification of the linear guide - that support rollers are attached to the side of the suspension element for vertical support of the sliding arm. On the other hand, it is also possible that the vertical support of the sliding boom is taken over either by the linear guide or by the stretcher bars. The latter are expediently equipped with support rollers for this purpose.

Gemäss einer weiteren erfindungsgemässen Ausgestaltung ist vorgesehen, dass in einer Ausgangstellung des oder der Gleitausleger die Abstände zwischen Rudersitz und Stemmbrett verstellbar sind, und dass entsprechend dieser Verstellung die Dolle auf dem Gleitausleger verschiebbar angebracht ist. Dadurch lässt sich der Rudersitz und/oder das Stemmbrett so verschieben und einstellen, dass jeder Ruderer seine Beine voll ausstrecken kann. Wird beispielsweise der Rudersitz längs der Bootslängsachse um eine bestimmte Strecke aus der Normalstellung verschoben, dann ist es vorteilhaft, wenn auch die Dolle auf dem Gleitausleger parallel um die gleiche Strecke verschiebbar ist. Zu diesem Zweck is nach einer Weiterbildung auf dem Gleitausleger eine Führungsschiene derart angeordnet, dass darin die Dolle um den maximalen Abstand verschoben werden kann, der dem Beinlängenunterschied zwischen dem grössten und kleinsten Ruderer entspricht. Mittels Festzieh- und Konterhebeln im Bereich der Dolle lässt sich eine solche Einstellung vom Rudererplatz aus bequem vornehmen.According to a further embodiment according to the invention, it is provided that in a starting position of the sliding boom (s), the distances between the rudder seat and stretcher board are adjustable, and that, according to this adjustment, the oarlock is slidably mounted on the sliding boom. This allows the rudder seat and / or the stretcher to be moved and adjusted so that each rower can fully extend his legs. If, for example, the rudder seat is moved a certain distance from the normal position along the longitudinal axis of the boat, then it is advantageous if the oarlock on the sliding boom can also be moved in parallel by the same distance. For this purpose, according to a further development, a guide rail is arranged on the sliding boom in such a way that the oarlock can be moved therein by the maximum distance which corresponds to the difference in leg length between the largest and smallest rowers. Such a setting can be conveniently carried out from the rowing place by means of tightening and locking levers in the area of the oarlock.

Zur Erleichterung der Unterbringung und des Transports sind die erfindungsgemässen G leitausleger mit Stemmbrett schnell einbau- une herausnehmbar und mittels Gelenkelementen klappbar ausgeführt.To facilitate storage and transportation, the sliding booms according to the invention can be quickly installed and removed with a stretcher and are designed to be foldable by means of articulated elements.

Durch die Koppelung der Gleitauslegerzu einem Gesamtausleger sind alle seitlichen Druck- und Zugkräfte so aufeinander ausgerichtet, dass sie sich weitgehend aufheben. Dadurch sind die Belastungen der Lager und damit die Anforderungen an die Biegesteifigkeit der Linearführung derart vermindert, dass diese leichtgewichtig hergestellt werden kann. Ausserdem werden Kugel- und Rollenlager eingespart, die andernfalls an jedem Ruderplatz vorgesehen werden müssten, um die erforderliche Laufruhe bei geringen Reibungsverlusten zu verwirklichen.By coupling the sliding booms to form an overall boom, all lateral compressive and tensile forces are aligned so that they largely cancel each other out. As a result, the loads on the bearings and thus the requirements for the bending stiffness of the linear guide are reduced in such a way that it can be manufactured in a lightweight manner. In addition, ball and roller bearings are saved, which would otherwise have to be provided at each rowing position in order to to achieve the required smoothness with low friction losses.

In der Praxis hat sich gezeigt, dass bei Einsatz eines Gesamtauslegers, der mittels z. B. Kugelbüchsen mit eingebautem Selbstausgleich von Fluchtungsfehlern längs der Linearführung geführt ist, die erforderliche Geradheitstoleranz zwischen den beiden entgegengesetzten Enden befindlichen Lagern (im Beispiel ca. 6 m - 60 m) ohne weiteres eingehalten werden kann. Im Bereich zwischen den beiden Gesamtauslegerendlagen können je nach Gleitausleger- und Bootsbeschaffenheit einfache Stützrollen genügen. Bei Verwendung von Lagern aus Kugelbüchsen auf einer Welle oder fluchtenden Wellenstükken, sollten diese Lager gummielastisch schwimmend eingebaut werden. Das «Schwimmen» der Lager gleicht statisch bedingte Verspannungen aus und verhindert, dass die Lagerbelastung die zulässigen Werte überschreitet; es darf jedoch nicht dazu führen, dass der Gesamtausleger ins Schwimmen kommt.In practice it has been shown that when using a full boom, which by means of z. B. Ball bushings with built-in self-compensation of misalignments along the linear guide, the required straightness tolerance between the two opposite ends of the bearings (in the example about 6 m - 60 m) can be easily maintained. In the area between the two total boom end positions, depending on the nature of the sliding boom and boat, simple support rollers can suffice. When using bearings made of ball bushings on a shaft or aligned shaft pieces, these bearings should be installed in a rubber-elastic floating manner. The "floating" of the bearings compensates for static stresses and prevents the bearing load from exceeding the permissible values; however, it must not cause the entire boom to swim.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Es zeigt:

  • Fig. eine Draufsicht auf ein erfindungsgemässes Ruderboot,
  • Fig. 2 eine Schnittansicht längs der Linie 11-11 der Fig.1,
  • Fig. 3 eine Schnittansicht längs der Linie III-III in Fig. 2.
An exemplary embodiment of the invention is explained in more detail below with reference to the drawing. It shows:
  • 1 shows a plan view of a rowing boat according to the invention,
  • 2 shows a sectional view along the line 11-11 of FIG. 1,
  • 3 shows a sectional view along the line III-III in FIG. 2.

Gemäss Fig. 1 umfasst das erfindungsgemässe Ruderboot verschiebbar angebrachte Gleitausleger 1 mit ausserbordigen Seitenflächen 2 und mit den Gleitauslegern 1 jeweils starr verbundenen Stemmbrettern 3. Ferner ist ein in seiner Stellung einstellbarer Rudersitz 4 vorgesehen, der während der Ruderfahrt bezüglich des Bootsrumpfes 11a ortsfest arretiert ist. Der-in Fahrtrichtung F gesehen - hintere Gleitausleger ist als Doppelausleger mit zwei Seitenflächen 2 auf jeder Seite des Bootes ausgebildet, wodurch die Möglichkeit zum Skullen anstelle vom Riemenrudern gegeben ist. Ferner sind die Seitenflächen 2 an ihren Rändern parallel zur Fahrtrichtung mit Dollen 5 versehen, die in Führungsschienen 6 verschiebbar aufgenommen sind. Neben der Führungsschiene 6 dient zur Positionierung der Dolle 5 in Bootlängsrichtung ferner ein Festziehhebel 7 und ein entsprechender Konterhebel 8. Diese beiden Hebel sind zweckmässigerweise so ausgebildet, dass der Ruderer sie von seinem Sitz 4 aus bequem betätigen kann. Die Stemmbretter 3 sind zur Förderung des Bewegungsablaufs beim Rudern um eine Stange 9 schwenk- oder klappbar.1, the rowing boat according to the invention comprises slidably mounted sliding booms 1 with extra-sided side surfaces 2 and stretcher bars 3 each rigidly connected to the sliding booms 1. Furthermore, a rudder seat 4 which is adjustable in its position is provided, which is locked in place with respect to the boat hull 11a during the rowing trip. The - seen in the direction of travel F - rear sliding boom is designed as a double boom with two side surfaces 2 on each side of the boat, which gives the possibility of sculling instead of oar rowing. Furthermore, the side surfaces 2 are provided at their edges parallel to the direction of travel with oarlocks 5, which are slidably received in guide rails 6. In addition to the guide rail 6 serves to position the oarlock 5 in the longitudinal direction of the boat a tightening lever 7 and a corresponding counter lever 8. These two levers are expediently designed so that the rower can operate them comfortably from his seat 4. The stretcher bars 3 can be swiveled or folded around a bar 9 to promote the movement sequence when rowing.

Die Stemmbretter 3 umfassen ferner eine weitere Stange 10, die als Auflage für die Fersen der Ruderer dient.The stretcher bars 3 further comprise a further rod 10, which serves as a support for the heels of the oarsmen.

Gemäss Ausführungsbeispiel nach Fig. ist eine Linearführung 11 innerhalb des Bootsrumpfes 11a angeordnet und umfasst im wesentlichen eine innere, durchgehende Welle 12, die von in Abständen voneinander angeordneten Stahlummantelungen oder Stahlhülsen 12a umgeben ist, sowie käfigartige Aufhängungselemente 13, worin auf den Stahlhülsen 12a laufende Rollen 14 eingeschlossen sind. Vorzugsweise sind die Innenwette 12 aus Kunststoff, z. B. G FK, und die Hülsen bzw. Ummantelungen aus Stahl, Metall oder dgl. hergestellt. Derart ausgebildete Innenwellen als Kern der Linearführung 11 sorgen für eine elastische Kompensation statischer Verspannungen zwischen Ausleger 1 und Bootsrumpf 11a, während die im Verhältnis zur Kunststoffwelle 12 weitgehend verformungsfesten Metallhülsen bzw. -ummantelungen 12a eine präzise Längsführung der Gleitausleger 1 garantieren. Die Rollen 14 sind innerhalb des Aufhängungselements 13 spielarm angelenkt.According to the exemplary embodiment according to FIG. 1, a linear guide 11 is arranged inside the boat hull 11a and essentially comprises an inner, continuous shaft 12, which is surrounded by steel casings or steel sleeves 12a arranged at intervals from one another, and cage-like suspension elements 13, in which rollers running on the steel sleeves 12a 14 are included. The inner bet 12 are preferably made of plastic, e.g. B. G FK, and the sleeves or jackets made of steel, metal or the like. Internal shafts designed in this way as the core of the linear guide 11 ensure elastic compensation of static tension between the jib 1 and boat hull 11a, while the metal sleeves or sheaths 12a, which are largely resistant to deformation in relation to the plastic shaft 12, guarantee precise longitudinal guidance of the sliding boom 1. The rollers 14 are articulated within the suspension element 13 with little play.

Ferner sind weitere Rollen 15 an den Gleitauslegern 1 angelenkt und in horizontalen Führungsschienen 16 lauffähig aufgenommen, die jeweils in Randbereich des Bootsrumpfes 11a sich in Bootslängsrichtung erstreckend angeordnet sind. Die horizontalen Führungsschienen 16 sind derart ausgebildet und angeordnet, dass sie ein Verlassen der entsprechenden Horizontalebene durch die Rollen 15 verhindern.Furthermore, further rollers 15 are articulated on the sliding arms 1 and are run in horizontal guide rails 16, each of which is arranged in the edge region of the boat hull 11a and extends in the longitudinal direction of the boat. The horizontal guide rails 16 are designed and arranged in such a way that they prevent the rollers 15 from leaving the corresponding horizontal plane.

Die Kopplung der Bewegungen zweier oder mehrerer Gleitausleger 1 ist gemäss vorliegendem Beispiel mittels einer flächigen Verbindungseinrichtung 17 realisierbar. Sie kann - je nach Anforderung - mittels punktiert angedeuteter Befestigungselemente 26 entfernt und wieder angebracht werden.According to the present example, the movements of two or more sliding arms 1 can be coupled by means of a flat connecting device 17. Depending on requirements, it can be removed and reattached by means of dotted fastening elements 26.

Gemäss Fig. 2 ist eine steife Stange 18 über beispielsweise Schweisspunkte 27 bewegungsschlüssig mit den Auslegern 1 verbunden. Eine die Stange 18 auf jeder Gleitauslegerhöhe unterbrechende Verriegelung 19 ermöglicht eine bewegungsmässige Ver- bzw. Entkopplung der einzelnen Gleitausleger 1. Die Stange 18 stellt somit eine weitere Möglichkeit zur Kupplung einzelner oder aller Gleitausleger 1 miteinander dar.2, a rigid rod 18 is connected to the brackets 1 in a movement-locking manner via, for example, welding points 27. A lock 19, which interrupts the rod 18 at each level of the sliding arm, enables the individual sliding arms 1 to be coupled or uncoupled in terms of movement. The rod 18 thus represents a further possibility for coupling individual or all sliding arms 1 to one another.

Zur Förderung der Entspannung des Ruderers beim Anziehen seiner Beine in die Auslage ist die Zwischenschaltung einer weichen Feder 20 in die steife Stange 18 zweckdienlich: sie fördert die Bewegung des Ruderers in die Auslage, stabilisiert so seinen Ruderrhythmus und kann damit die Harmonie beim Mannschaftsrudern fördern. Beim Gleiten der Beine des Ruderers in die Rücklage wird die weiche Feder 20 ausgelenkt und gespannt. Um dabei kurz vor Erreichen der Rücklageendstellung für den Gleitausleger 1 eine stossfreie Abbremsung zu gewährleisten, ist eine weitere, harte Feder 21 gemäss Ausführungsbeispiel mit der weichen Feder 20 in Serie geschaltet, wobei erst bei Erreichen der Rücklageendstellung z. B. durch eine überlagerte Stahlsehne (nicht gezeigt) ausgelenkt wird.To promote the relaxation of the rower when putting his legs on the display, the interposition of a soft spring 20 in the rigid rod 18 is useful: it promotes the movement of the rower in the display, thus stabilizing his rowing rhythm and can thus promote harmony when team rowing. When the rower's legs slide into the reserve, the soft spring 20 is deflected and tensioned. In order to ensure shock-free braking for the sliding boom 1 shortly before the end position of the reserve is reached, a further, hard spring 21 according to the exemplary embodiment is connected in series with the soft spring 20. B. is deflected by a superimposed steel chord (not shown).

Gemäss Fig. 3 kann das Ruder der Körperbeschaffenheit des Ruderers angepasst werden, indem das Längenverhältnis des Ruderinnenhebels 22 zum Aussenhebel 23 über einen den Ruderholm umgebenden, mehrstufigen Dollenring 24 (Mehrfachdollenring) variierbar ist. Der Erleichterung des Transports und der Unterbringung dient schliesslich ein als Scharnier mit Konsole ausgebildetes Klappelement 25. Eine zweckmässige Klappbewegung ist mit dem runden Pfeil gemäss Fig. 3 angedeutet.According to FIG. 3, the rudder can be adapted to the rower's physical condition by varying the length ratio of the inner rudder lever 22 to the outer lever 23 via a multi-stage oar ring 24 (multi-oar ring) surrounding the oar spar. Finally, a folding element 25 designed as a hinge with a console serves to facilitate transport and accommodation. A purpose moderate folding movement is indicated by the round arrow according to FIG. 3.
