Abstract

The safety basket (1) consists of connected shaped rods and fixing screws (2) for the motor shaft casing (3). The propeller (4) is under the motor shaft casing and is connected to the motor shaft (5). The grid formed by the basket is so designed that suction and outflow criteria to ensure low-energy operation are met.

Description

Die Erfindung betrifft eine Vorrichtung als Schutzeinrichtung bei Betrieb von Außenbordmotorschrauben, die universell für unterschiedliche Außenbordmotorschraubentypen anwendbar ist.The invention relates to a device as a protective device when operating outboard motor screws, which is universally applicable for different outboard motor screw types.

Schutzeinrichtungen für den Betrieb von Außenbordmotorschrauben in mehrflügeliger Ausführung sind nicht bekannt und nicht im Einsatz, die den Kontakt und die Berührung der Außenbordmotorschraube mit Fremdkörpern, insbesondere Menschen und Tieren, die bei Betrieb von Außenbordmotorschrauben an­ gezogen werden können, verhindern.Protective devices for the operation of outboard motor screws in multi-wing design are Not known and not in use that have the contact and touch of the outboard motor screw Foreign bodies, especially humans and animals, that operate when using outboard motor screws prevent can be pulled.

Vorrichtungen vor motorgetriebenen Schiffsschrauben im Wasser sind als Strömungsleitkammern zur Messung der Antriebsenergiemengen oder zur Verbesserung der Strömungsverhältnisse bekannt.Devices in front of motor-driven propellers in the water are used as flow guiding chambers Measurement of the amount of drive energy or known to improve the flow conditions.

Bei der Erfindung handelt es um eine Schutzvorrichtung in Form eines Korbes aus Profilstäben zur Ver­ meidung ungewollter Berührungen im Außenbordmotorbetrieb.In the invention, it is a protective device in the form of a basket made of profiled bars for Ver Avoid unwanted touches in outboard engine operation.

Mit dem Sicherheitskorb für Außenbordmotorschrauben in Wasserfahrzeugen im Anspruch 1 wird der hinreichende Schutz vor Berührungen, Unfällen und Schäden erreicht. Die Auswertung bisheriger Unfälle mit Menschen im Badebetrieb, die zunehmend auftreten, hat zu der Schutzvorrichtung in korbähnlicher Ausführung vor Außenbordmotorschrauben geführt.With the safety cage for outboard engine screws in watercraft in claim 1 adequate protection against contact, accidents and damage has been achieved. The evaluation of previous accidents With people in the bathing establishment who increasingly appear, the protective device has become more basket-like Version guided in front of outboard motor screws.

Der Schutz vor Berührung einer Außenbordmotorschraube ist mit dem Sicherheitskorb als Profilstabkon­ struktion gelöst, der den Einfluß von außen auf die motorgetriebene Schraube verhindert. Gleichzeitig ist mit dem Anspruch 2 der Sicherheitskorb so ausgebildet, daß die Energieverluste, die durch den Strö­ mungswiderstand vor der Schraube auftreten, minimal sind. Die Sicherheitskorbkonstruktion ist als weitmaschig und geschlossene Einrichtung ausgebildet, so daß das Berühren der Außenbordmotor­ schraube durch Fremdkörper, insbesondere durch Menschen, Tiere und Pflanzen verhindert wird.Protection against touching an outboard motor screw is with the safety cage as a profile rod structure solved, which prevents the external influence on the motor-driven screw. At the same time formed with the claim 2 of the safety cage so that the energy losses caused by the current resistance in front of the screw are minimal. The safety cage construction is as wide-meshed and closed facility designed so that touching the outboard motor screw is prevented by foreign bodies, in particular by people, animals and plants.

Der Anspruch 3 wird dadurch realisiert, daß die Profilstäbe des Sicherheitskorbes ellipsenförmig im Querschnitt ausgebildet sind und sich in der Anordnung den Sog- und Abströmverhältnissen optimal an­ passen. Ein Profilstab des Sicherheitskorbes wird in seiner Längsrichtung, entsprechend der Nutzung des ellipsenförmigen Querschnittes für eine Reduzierung der Energieverluste, in sich verdreht. The claim 3 is realized in that the profile bars of the safety cage in the shape of an ellipse Cross section are formed and the arrangement optimally adjusts to the suction and outflow conditions fit. A profile bar of the safety cage is in its longitudinal direction, according to the use of the elliptical cross section for a reduction of energy losses, twisted in itself.  

Das Ausführungsbeispiel eines Sicherheitskorbes für den Betrieb von Außenbordmotorschrauben ist in der Zeichnung dargestellt.The embodiment of a safety cage for the operation of outboard motor screws is in shown in the drawing.

Fig. 1 und 2 zeigen in zwei Ansichten den Sicherheitskorb (1) aus längs- und querverbundenen Profil­ stäben und die Befestigungsschrauben (2) am Motorschaft. Die Außenbordmotorschraube (4) ist unter dem Motorschaft (3) angeordnet und mit der Welle (5) zum Motor verbunden. Fig. 1 and 2 show two views of the safety cage (1) of longitudinal and transverse rods connected profile and the attachment screw (2) on the motor shaft. The outboard motor screw ( 4 ) is located under the motor shaft ( 3 ) and connected to the shaft ( 5 ) to the motor.

Claims (3)

1. Der Sicherheitskorb für Außenbordmotorschrauben, der der Abweisung von ungewollten Kontakten bedingt durch Sogwirkung und der Unfallverhütung für Menschen, Tiere und sonstige Fremdkörper dient, ist so ausgebildet, daß eine korbähnliche Vorrichtung aus einem Geflecht von Profilstäben dem Motorschaft universell angepaßt und sicher befestigt ist.1. The safety cage for outboard engine screws, the rejection of unwanted contacts due to suction and accident prevention for people, animals and other foreign bodies is designed so that a basket-like device made of a mesh of profile bars Motor shaft is universally adapted and securely attached. 2. Der Sicherheitskorb für Außenbordmotorenschrauben hat eine derartige Ausbildung, daß die geome­ trische Gitterausführung in Längs- und Querrichtung die strömungsgünstigen Kriterien mit Sog- und Abströmverhältnissen im Fahrbetrieb berücksichtigt und einen energiearmen Betrieb garantiert.2. The safety cage for outboard motor screws has such a design that the geome trical grid design in the longitudinal and transverse directions the aerodynamic criteria with suction and Flow conditions in driving operation are taken into account and low-energy operation is guaranteed. 3. Das Profil der einzelnen Gitterstäbe des Sicherheitskorbes ist nach den Strömungskriterien bestimmt und weist annähernd einen ellipsenförmigen Querschnitt aus. Die Profilstäbe des Sicherheitskorbes sind in sich so verdreht ausgeführt, daß eine Anpassung an die Strömungsverhältnisse erfolgt.3. The profile of the individual bars of the safety cage is determined according to the flow criteria and has an approximately elliptical cross section. The profile bars of the safety cage are designed to be twisted in such a way that they are adapted to the flow conditions.
