Abstract

The bridge structure (1) is for dismantlable water-, land- or ice-borne recreational craft. It has a rectangular top frame, pref. of round or oval section light alloy, strengthened by intermediate struts either side of an parallel to the craft centreline. Transverse brackets for connection to hulls, runners etc. run between struts angled downwards and inwards/outwards from frame corners and crossbar middle respectively. The front brackets have two bolt holes each; the rear brackets, one. The bolts are a close fit in the holes and screw into bushes flush with the hull.

Description

fftei çav'Y'' z ) zuzu>L tal r' lr Sportgerätebrücke für erlaubare Schwimm-Straßen- oder Eis- 1. fftei çav'Y '' z) zuzu> L tal r 'lr Sports equipment bridge for permitted swimming, street or ice 1.

Die Erfindung betrifft eine Sportgerätebrücke aus Leichtmetall nach der Oberbegriff des Patentanspruchs I.The invention relates to a sports equipment bridge made of light metal the preamble of claim I.

Es sind bereits Sportgerätebrücken,zum Beispiel bei Doppelpumpfbooten bekannt,die ausschliesslich für ein bestimmtes gerät ausgelegt sind und bei denen die Querstreben mit den Längsstreben über formstabile Winkelsteife,rechtwinklige Eckmulfen zu verbinden sind, vorzugsweise durch Ineinanderstecken,wobei die entsprechenden Verbindungen jeweils durch mehrere über den Mulfenumlang verteilte Schrauben gesichert werden müssen.Da üblicherweise mindestens zwei Schrauben pro Strebenende als erforderlich angesehen werden,ergeben also sich bei vier Eckmuflen insgesamt sechzehn Schraubverbindungen,die beim Aufbauen sorgfältig festgezogen und beim Abbauen wieder gelöst werden müssen.There are already sports equipment bridges, for example on double pump boats known, which are designed exclusively for a specific device and where the cross struts with the longitudinal struts via dimensionally stable angular stiffeners, right-angled Eckmulfen are to be connected, preferably by plugging into each other, the corresponding Connections are each secured by several screws distributed over the length of the mulch Since usually at least two screws per strut end as required are viewed, so there are a total of sixteen screw connections with four corner sockets must be carefully tightened when assembling and loosened again when dismantling.

Aufgabe der Erfindung ist die Schaftung einer demgegenüber verbesserten Sportgerätebrücke,welche eintach,sowie bei geringerem Zeitaufwand aui-und abzubauen ist und für verschiedene Sportgeräte zu verwenden ist.Erreicht wird dies durch die kennzeichnenden Merkmale des Patantanspruchs I.The object of the invention is the shaft of a comparatively improved Sports equipment bridge, which is easy to assemble and dismantle with less expenditure of time and can be used for various sports equipment. This is achieved by the Characteristic features of claim I.

Durch den Erfindungsgegenstand wird erreicht,das lediglich die Brücke als gesamtes mit den dafür vorgesehenen Buchsen zu verbinden ist,was eine enorme Zeit-und Arbeitsersparniss bedeutet.Durch die Brückenkonstruktion,die eine feste Einheit darstellt,und so ausgebildet ist, das sie völlig verwindungslest ist und einen starren Rahmen bildet, Mittcls sechs schraubbolzen ann diese Sportbrücke absolut test und steil mit dem jeweiligen Sportgerätuntersatz verbunden werden.The subject of the invention achieves that only the bridge as a whole is to be connected to the designated sockets, which is an enormous one Time and labor saving means. Due to the bridge construction, which is a solid Represents unity, and is designed so that it is completely torsion-resistant and Forms a rigid frame, with six bolts absolutely attached to this sports bridge test and steep can be connected to the respective sports equipment base.

Diese eine Brückenkonstruktion kann also für Doppelrumpfboote, Segelbrettkatamarane(Surfcat),Eissegler mit Kufen anstatt Rümpfen, sowie als Strandsegler mit Reiten verwendet weiden.This one bridge construction can therefore be used for double-hulled boats, sailing catamarans (surfcats), ice sailors graze with runners instead of hulls, as well as used as sand yachts with riding.

Die vordere Brückenstrebe dient mittels aufgeschraubten Gummibolzen zur Aufnahme des teilbaren Mastes,während die hintere Querstrebe zur Aufnahme des Ruders dient.The front bridge strut is used by means of screwed-on rubber bolts to accommodate the divisible mast, while the rear cross strut to accommodate the Rudder is used.

Die Spritzdecke ist zwischen Quer-und Längsstreben in bekannter Weise eingehangt.The spraydeck is between the transverse and longitudinal struts in a known manner hung.

Durch die konstruktiven Merkmale nach dem patentanspruch I wird erreicht,das die der Sportgerätebrücke eigene Stabilität voll und mittels sechs Schraubbolzen auf das Sportgerät übertragen werden kann.The structural features according to claim I achieve that the stability inherent in the sports equipment bridge fully and by means of six screw bolts can be transferred to the sports equipment.

Die Erfindung ist nachstehend anhand der Zeichnung näher erläutert.The invention is explained in more detail below with reference to the drawing.

Es zeigen: Fig.I ein Ausführungsbeispiel einer Sportgerätebrücke auf einem Segelbrettdoppelrumpfboot(Surfcat).They show: FIG. 1 an exemplary embodiment of a sports equipment bridge a sailboard double hull boat (Surfcat).

Fig.2 einen Bereich von Fig.I in demgegenüber vergrößerter Darstellung, Fig.3 eine chematische Darstellung der Sportgerätebrücke.von vorne, bzw.hinten,in Draufsicht,sowie Seitenansicht.FIG. 2 shows an area of FIG. Fig. 3 a chemical representation of the sports equipment bridge. From the front and rear, in Top view and side view.

Wie sich am besten aus Fig.I ergibt,kann diese Sportgerätebrücke für verschiedene Spoertgeräte verwendet werden,da die für die Schraub-bzw.Bcestigungsbolzen vorgesehenen Buchsen versenkt,also nicht vorstehend in die Sportgeräte oder Schwimmkörper eingelassen sind.As can best be seen from Fig.I, this sports equipment bridge for Different Spoertgeräte are used, as those for the screw or fastening bolts provided sockets sunk, so not protruding into the sports equipment or floats are let in.
