FR2613317A1 - Articulated rudder or fin well, accessory to nautical craft - Google Patents

Abstract

The invention, associated with nautical craft provided with fins, with unshippable rudders, makes it possible to make them pass over a hard surface without them having originally been made specifically for this purpose. It comprises a plate 1 screwed 2, extended towards the outside of the craft, where there is located a pin 3. On this pin 3 there is fixed, in the movable part, a plate 4 for supporting a fin 9, a rudder 9 or their respective well 5 by means of screws 6. A spring 8 mounted on a rod 7 repositions the articulated assembly after the craft has passed over a hard surface. Amongst the most beneficial applications of the invention, mention may be made of passing a sailboard over a springboard; passing a boat over shallows.

Description

 The present invention is an accessory to nautical vessels fitted with fins, removable rudders.

 I1 makes it possible to retract the aileron, the rudder during the passage of the machine on a hard surface.

 In known devices of this kind, a fin, a rudder held by an axis of rotation, in the center of its well. The fall back is then only possible with a location previously prepared for manufacture.

 Such devices remain included in the device and make it specific. installation is final requiring thickness, strength of the machine. They restrict the use of ailerons, rudders defined by the manufacturer.

 The device according to the invention avoids these drawbacks. 11 comprises a plate fixed to the original location of the aileron, of the rudder of the craft.

The other end of the plate, outside the machine, an axis. n mobile part on this axis, a support plate of another fin well, rudder, of the same type, different, or of a fin, of a single rudder.

Maintaining the navigation position is obtained by the weight of the articulated assembly or by a spring.

 The device according to the invention allows easy, rapid disassembly for all types of machine provided with a fin and removable rudder, for the passage of the latter over a hard surface, without their having the specificity of origin. it allows the installation of a fin, uc governai different from the origin, without transformations of the craft.

 the accompanying drawing is a sectional view of the device in the navigation position; said initial.

 As presented, the device comprises a plate (l) secured to the fin well, the rudder of the machine, or even the latter, by screws (2). At the end of the plate (), outside the machine, an axis (3) on which stands e mobile part a support plate (4); forming the joint. To the support plate is fixed a fin well (5), degouverail (5) by screws (6). On both sides of the axis (3), a semicircle rod, two of which ends are fixed to plate (I), crosses the plate as support. Threaded on the title (), a spring gripping sepis on the plate (@) and the articulated part.

 When the aileron, the rudder meet a hard surface, they go up while entraining the articulated part which compresses the spring. As soon as the anthagonistic force, at the own weight of the aticulated assembly or the spring is less than the aileron, the rudder return to the navigation position; said initial.

 The device according to the invention can be installed removed easily, precisely, quickly on all nautical craft provided with removable rudder fins.

Especially so that they can pass over a hard surface. It can be used in the nautical, industrial and domestic fields.

 es particularly interesting applications can be por the passage of a sailboard on a springboard, a boat on a bottom hat. It gives the possibility of fixing a spoiler, a rudder of a mounting different from the origin.
