EP1205382B1 - Holding arrangement for the deck of a sailboat - Google Patents

Abstract

The deck retaining mechanism for a sailing vessel with a hull (C) and a mast (M) passing through the deck (P) and fastened to the hull at keel level consists of stops (B) fixed to the mast just above deck level and connected by adjustable screws to a thrust plate (I') on the deck round the mast. The screws are adjusted to counteract the lifting force on the deck applied by mast rigging lines (D) passing through pulleys (R).

Description

The present invention relates to decked sailing boats.

The masts of decked sailing boats can be placed either on the deck, either on the keel. However, a mast exerts strong compression on its seated.

If, as shown in Figure 1, a mast M rests on the support above a P bridge, it is necessary, to avoid sinking of the P bridge, to transfer the compression of the bridge to the keel Q using a part E called mast tackle. The mast base, bridge, pedestal and keel stabilizes so the P bridge at a fixed position relative to the Q keel.

In addition, in many cases, halyards, hale-bas or others elements D of the current rigging extending along the mast M are returned along bridge P by means of deflection pulleys R struck on a plate I forming the mast base. When the boat is under sail, these elements D of the current rigging are subjected to high tension and the force F applied to pulleys R has a component F1 parallel to the mast M which tends to lift bridge P.

In the case shown in Figure 1 of a mast M placed on a bridge P, the components F1 of the forces exerted by the elements D of the current rigging on the pulleys R are taken up by the mast M on which the pulleys are fixed, sometimes by means of the mast base or the stern collar. The epontail E serves to avoid the penetration of the bridge P under the pressure exerted by the mast M. The compression force of the mast is greater than the component of the forces exerted by the halyards which tends to raise the bridge.

By cons, in the case shown in Figure 2 of a mast M resting at bottom of the hull on the keel Q, this mast M freely crosses the deck P, and a plate of stambrai l 'fixed on this one, by an opening O called passage mast hole. There is therefore no link between the P bridge and the M mast and the bridge can so go up if an F1 pull is exerted upwards due to the elements D of the current rigging passing through the idler pulleys R.

To avoid this phenomenon, it is known to hold bridge P in the vicinity of the mast M by means of tie rods integral with the mast or the mast foot.

In the example shown on the left side of Figure 2, the T1 tie rods (only one of which is shown) consist of a cable or rod (monofilament) and a rigging screw fixed along the mast between the plate I 'and the mast foot Z integral with the keel Q. The rigging screw compensates for the tolerances of manufacturing between bridge P and the mast foot Z and ensuring fine adjustment.

Alternatively, as shown on the right side of Figure 2, the tie rods T2 can be fixed between the plate I 'and part of the mast M about 20 to 50 cm below the P deck.

This tie-rod retainer is expensive because it requires each pulling a turnbuckle and means of fixing the tie, on the one hand on the mast M or the mast foot Z, and on the other hand on the stage plate I 'through Pont P. In addition, it is unsightly since, located under the bridge, it is visible from inside the boat, usually a habitable part of it. Finally, it is inconvenient to use since the adjustment of the tie rods is done inside of the volume delimited between the deck and the hull while the standing rigging ensuring the mast is held relative to the hull is adjusted from the outside.

In addition, in a sailing boat, the standing rigging ensuring the holding the mast relative to the hull also exerts tensile forces on the chainplates to which it is attached.

The chain stays and lower shrouds are fixed either on the liston of the boat, either on deck in a retracted position towards the longitudinal axis of this one.

The forces exerted on these CA chainplates by the H shrouds and the lower shrouds BA, although they are generally taken up by a partition CL (as shown in Figure 1) or a T3 tie rod (as shown in figure 2), contribute with the aforementioned elements of the current rigging to the lifting the bridge.

Of course, this problem of lifting the bridge by the shrouds does not arise in the case of a non-guyed mast, planted in the hull, as described for example in document DE 18 663.

The invention aims, in the case of a mast crossing the bridge, to overcome disadvantages of the devices of the prior art thanks to a particularly simple, inexpensive and aesthetically satisfactory which allows to oppose the lifting of the bridge under the effect of the efforts likely to be exerted in particular by the running and / or standing rigging.

To this end, the invention relates to a bridge retaining device for sailing boat, said bridge being crossed by at least one mast and capable of to be subjected, in the vicinity of said mast, to lifting forces, characterized in that said device comprises at least one stop means for said bridge mounted on said mast above said bridge.

• FIG. 7 is a partial perspective view illustrating a mast fitted with the bridge retaining device of the second embodiment of FIGS. 5 and 6.

Referring to Figures 3 and 4, a sailing boat includes a hull C closed by a bridge P that crosses, by a stern opening O a mast M whose foot Z is supported and is fixed, at the bottom of the shell C, on the keel Q of it. Typically, a stage plate is crossed by mast M and fixed to bridge P by screws or bolts (not shown). On the stern plate I 'are hung pulleys of return R used to return elements of the current rigging to deck P extending along the mast M, for example halyards D for the establishment a jib and / or a mainsail.

In addition to the H stays and BH lower shrouds of the standing rigging of the M mast are fixed to CA chain locks. The padlocks can be attached to a partition or a tie rod (as shown in Figures 1 and 2) contributing to resume the efforts of the standing rigging.

In order to prevent the lifting of the P bridge under the effect of the component F1 of the force F applied to each pulley R by the tension exerted on the corresponding halyard D and / or under the effect of the forces exerted by the CA chain locks, the M mast is equipped laterally with two means of stop B. As shown in FIG. 3, these two stop means B can be identical and symmetrically arranged on either side of the mast relative to a longitudinal plane of symmetry of the boat. According to the needs, the retaining device may include only one stop means B or more than of them.

Each stop means B comprises a massive piece 1 made secured to the mast M, for example by riveting. Part 1 is pierced between its upper and lower faces of a threaded bore substantially parallel to the mast M and in which is received a screw 2 whose lower end is in support against the stage plate I 'and thus serves as a stop for the bridge P when the latter is subjected to the aforementioned F1 forces. By moving the screw 2 by compared to part 1, it is thus possible to finely adjust the position of the bridge P along the mast M, at the stern passage O.

In FIGS. 5 to 7, the same reference signs have been used as in Figures 3 and 4 to designate corresponding elements.

In this second embodiment, there are also provided two bridge stop means B1 and B2, but these are arranged on the faces front and rear of the mast M and their fixed part 1 is constituted by an element which is generally present on most sailing boats.

Thus the fixed part 1 of the stop means B1, on the rear side of the mast, is made up of a jack-up, part which by definition must be very resistant and perfectly secured to the mast M just above the pont P. This downhaul socket 1 is provided with an axial threaded bore receiving screw 2 to form a stop means opposing the lifting from P. bridge

Likewise, on its front face, opposite to the jack of low, the mast M of a sailing boat is generally equipped with a rail 3 along which can slide a carriage (not shown) intended to receive the end of a pole (not shown). A stopper is arranged at the lower end of the rail 3 to limit the travel of the outrigger carriage. Insofar as this stop of outrigger carriage is placed at a suitable distance from bridge P, it can therefore, by providing a tapped bore to receive the screw 2, constitute the fixed part 1 of the second stop means B2 as shown in FIG. 6.

The bridge restraint described above has many advantages over the solutions of the prior art.

Thus, compared to the tie rod solution of Figure 2, it eliminates the need for expensive adjusting turnbuckles, anchoring means in the stage plate the and on the mast M or the foot of mast Z, and corresponding machining. The device thus makes it possible to use, under the bridge, a fixed lining around the mast, without fittings outside the profile mast, giving a better finished cabin interior.

The bridge restraint described above is of a construction particularly simple and inexpensive using one or more screws standard, for example of the BTR type, much less expensive than turnbuckles. The masting and dismasting of the boat are greatly facilitated because all parts of the bridge retainer against lifting are protruding above it. In addition, the settings are not lost when the mast is removed because dismasting does not involve any intervention on the screws 2.

It goes without saying that the embodiments described are only examples and we could modify them, in particular by substitution technical equivalents, without departing from the scope of the invention.

Thus, for example, that one or both stop means B1 and B2 of the second embodiment can be combined with one or more stop means B of the first embodiment.

The adjusting screw 2 can be immobilized in the desired position by relative to the fixed part 1, for example by a lock nut.

More generally, the adjustment of the position of the bridge relative to the mast is not limited to the use of a screw and any means providing the same adjustment function could be substituted for it.
