DE102009004039A1 - Shroud fastener for sail-surfer rigs, has belt system fixed from outside by mast pocket and sail, and loop winding mast within mast pocket for transferring transverse forces from bracing - Google Patents

Abstract

The fastener has shrouds (5) connected with a fastening point before a mast pocket in approximately 3/4 of pole height. A belt system is fixed from outer side by a mast pocket (1.1) and a sail (1). Forces from a forestay (4) and the shrouds are received by two tension flanges (6.2) and a transverse belt (6.4) of a belt system (6) such that the tension flanges stay in operative connection with a mast head (3.1) and/or a sail head (1.2) at the transverse belt in an area. A loop (6.1) winds a mast (3) within the mast pocket for transferring transverse forces from bracing.

Description

The The invention relates to a Wantbefestigung for sailors Riggs, which these as with a guyed rigged rigging on sailing equipment with Forestay and shrouds are mountable.

Sailing Surfer Riggs opposite the usual Sailboat rigging in front of the sail on a mast pocket in which the mast is inserted during assembly. The Sailors Rig will be from the Operator held by a boom and to control the surfboard panned on all sides. However, there are also applications where such rigs in upright and not tiltable to windward or leeward Position installed on other sailing or / and watercraft are. As examples can here the following products are called: "Ma-Jet", sailing technology, Stuttgart A) and "K3", Lipro GmbH, Alfdorf B). The advantage of using a surfer rig is in the cheap Price of sails from mass production and the efficient sailing aerodynamics, with the rig almost as rigid wing acts. Thus, you can dinghies, which are often complex in dinghies, Liekstrecker, Traveler, etc. omitted. This results in another Advantage, namely the simple operation, what for Marketing in grassroots sport is important.

at o. g. Example A), the mast by means of a U-shaped strut supported. This is at the boom-neckline the mast pocket and mounted on both sides of the hull. In upright Riggposition and strong wind blowing but the upper 2/3 of the sail and becomes uncontrollable. In contrast, can be a sailor Rigg tilt and stabilize strongly to windward.

At the Example B) was therefore the mast with a saling and various wires exhausted, but this significantly increases the complexity and rapid Mounting conflicts.

So it makes sense to clamp the mast conventionally with forestay and shrouds. When surfing rigging, however, it is necessary to have an opening in the mast pocket provided on top of the mast and there a corresponding Fitting for the connection of forestay and shrouds to install. Such a fitting with eyelet could be attached to the mast by means of rivets or screws. It stands but contrary to that, in particular surfer-carbon masts very notch sensitive are and drill holes to break. something similar would one Too strong clamping of the fitting on the mast effect. Another one Problem is the very narrow mast pockets modern surf sails, what should reduce the water absorption in case of fall. Thus could any Mast fittings only be mounted after stretching the sail, as they are not in fit the mast pocket. However, this is extremely impractical for the assembly and it is also to ensure that the fitting high forces of several 100 kg, including a clamp extremely tight would have to sit.

• – Eignung zur Aufnahme großer Kräfte in Längs- und Querrichtung des Masts in ca. ¾ der Masthöhe
• – Das Befestigungsmittel soll bei kleiner Masttasche anwendbar sein
• – Vermeidung von Kerbwirkung am Mast
• – Nur geringer Ausschnitt in der Masttasche
• – Einfache Montage

Thus, the inventive task to find a solution for attachment of forestay and shrouds on a sailurfer mast with the following characteristics:

• - Suitable for absorbing large forces in the longitudinal and transverse direction of the mast in approximately ¾ of the mast height
• - The fastener should be applicable to a small mast pocket
• - Avoidance of notch effect on the mast
• - Only a small section in the mast pocket
• - Easy installation

The inventive solution exists from a belt system that can be mounted on the rig from the outside is and in about ¾ of the mast height has a wrap around the mast and from there over two drawstrings left and right of the mast pocket to an anchorage at the top of the mast runs. The straps are preferably made of polyester mesh with a cross section of about 25x1.5 mm. In the clamped state, they rest against the mast pocket, so that the air flow around the sail hardly disturbed becomes. The o. G. Mastumschlingung consists of a cross belt of about 40 × 1.5 mm, the best pulled several times around the mast, rotatably mounted and Z. B. is secured with a Velcro or clamp. The Assembly is very easy to perform. The two pull straps are connected at the lower end with the cross belt; located at the front a stable loop with a shackle for forestay and shrouds. The pull straps and strap are with the cross belt either sewn, riveted or glued.

Of the Cross belt penetrates the mast pocket between the mast and the pocket seam on two vertical slots. In this area is only a slight tension present, as the larger forces in the sail act further back. The air force in the sail becomes essentially taken up by the windward, which extends to the mast in the longitudinal direction Exerting pressure; in the transverse direction, only the air force acts. It sits down the longitudinal load as pulling forces in the two Zuggurten from, with o. Loop with the cross strap in the direction of Luvwant. This will cause the leeward Tension belt over pulled the slightly curved mast end, being part of the train transferred by friction to the mast and so on the masthead is relieved.

The suitability of the invention for use even in a tight mast pocket is ensured by the fact that no fittings must be attached to the mast. Also, the inventor avoids because of the wide circulation and the play storage of the cross belt notch effect on the mast.

As mentioned above, the cross belt is pulled around the mast through slots in the mast pocket and subsequently z. B. secured with Velcro. The transverse belt thus forms a movable ring, which the mast loosely encloses. Thus, the belt system can remain on the sail even when disassembling the mast and rolled up together with the lath sail.

forestay and shrouds need only during assembly in the loop on Sled in a crossbelt to become. As a result of fixed in certain mast height by the cross belt Base forestay and shrouds have constant lengths, so the pressure point of the sail - important for the boat trim remains in the same position.

The The invention is illustrated and described by figures, it shows

1 shows an overview of the relaxation of a sailurfer rig by means of forestay ( 4 ), Shrouds ( 5 ) and the belt system according to the invention ( 6 ). The rig consisting of sails ( 1 ), (mast bent at sail mounting) 3 ) and boom ( 2 ) is replaced by forestay ( 4 ) and shrouds ( 5 ) held. These are approximately ¾ of the mast height with a loop ( 6.1 ) of the belt system ( 6 ), so that the rig also with larger wind strength - in addition led by the sail sheet ( 7 ) - little can blow out.

The mast ( 3 ) is via the mast foot joint ( 8th ) with the hull ( 9 ) releasably secured. By means of the joint ( 8th ), the rig - similar to surfboards - can be laid flat, which is used for rigging. In addition, this function is solved by solving a Want ( 5 ) in an emergency, z. As in storm, advantage. When rigging from the laid flat state, the two shrouds ( 5 ) at the hull ( 9 ) and on the loop ( 6.1 ) by shackle ( 6.3 ) attached. The forestay ( 4 ) is also fixed there with one end, while the other end is used by train to erect the rig. When the vertical rigging position is reached, the forestay ( 4 ) on the hull ( 9 ) are latched.

As can be seen from the drawing, the belt system ( 6 ) of two tension belts ( 6.2 ), each on one side of the sail ( 1 ), as well as a transverse strap ( 6.4 ). The pull straps ( 6.2 ) connect the Wantbefestigungspunkt - as a loop ( 6.1 ) - with the masthead ( 3.1 ), so that the forces from Vorstag ( 4 ) and shrouds ( 5 ) can settle.

In 2 is the belt system ( 6 ) in detail. The longitudinal straps ( 6.2 ) left and right of the sail ( 1 ) end in the lower part in the loop ( 6.1 ), which has a shackle ( 6.3 ). At this are forestay ( 4 ) and shrouds ( 5 ) attached. As described above, take the longitudinal straps ( 6.2 ) from Vorstag ( 4 ) and shrouds ( 5 ) resulting forces in the direction of gearing. The transversely acting force component of the air force is essentially transmitted via the transverse belt (FIG. 6.4 ) from the mast ( 3 ) on the Luvwant ( 5 ) transfer. The cross belt ( 6.4 ) wraps around the mast ( 3 ), as in 3 shown in more detail. The mast wrap is made by longitudinal cuts ( 1.4 ) in the mast pocket ( 1.1 ), through which the transverse belt ( 6.4 ) to be led.

The cross belt ( 6.4 ) has a safety belt ( 6.5 ), which is designed here as Velcro backing. As an alternative security devices come z. B. clamp or buckle solutions in question. The upper ends of the longitudinal straps ( 6.2 ) by a length-adjustable sheet ( 6.6 ) - as a tension element of the straps ( 6.2 ) - with the masthead ( 3.1 ) connected. There - depending on the version - or on the sail head ( 1.2 ), the transmission of the longitudinal forces takes place. Instead of the sheet ( 6.6 ) are also other clamping devices z. B. integrated with the straps ( 6.2 ) possible.

In sailing operation causes a stronger load the Luvwant ( 5 ), that the loop ( 6.1 ) together with the cross belt ( 6.4 ) moves towards the windward side. The rotational movement of the belt ( 6.4 ) is possible because its wrap around the mast ( 3 ) Game has. The displacement of the loop ( 6.1 ) results in a lower load on the mast top ( 3.1 ) as described above.

Will the mast ( 3 ) when disassembling from the mast pocket ( 1.1 ), the belt system ( 6 ) on the sail ( 1 ) and to be rolled up with this (see above). When retrofitting rigs, it is thus only a small amount of time, the clamping sheet ( 6.6 ) at the mast top ( 3.1 ) to install. If the clamping sheet ( 6.6 ) on the sail head ( 1.2 ) hinged, eliminates any additional installation work.

3 shows side view ( 3a ) and section ( 3b ) in the region of the transverse belt ( 6.4 ). The wrap around the mast ( 3 ) is separated by two small slots ( 1.4 ) in the mast pocket ( 1.1 ). In 3a is indicated by arrows, as the main tensile forces on the pocket seam ( 1.3 ) and the front area of the sail ( 1 ) to distribute. The maximum tension on the sail ( 1 ) in the axis masthead ( 3.1 ) and mast base (see bow / tendon). In contrast, the mast pocket ( 1.1 ) little loaded, so from the slots ( 1.4 ) can not crack. Below the cross belt ( 6.4 ) is the loop ( 6.1 ) arranged the shackle ( 6.3 ). With this are forestay ( 4 ) and shrouds ( 5 ) connected.

From the sectional drawing in 3b it can be seen that the transverse belt ( 6.4 ) the mast ( 3 ) wraps around several times, with a belt securing ( 6.5 ) z. B. is provided as a Velcro strip. Other backups with just one wrap are of course possible as well. As described above, the transverse strap ( 6.4 ) when loaded, turn in the direction of the windward edge, with the forces acting on both tie-down straps ( 6.2 ).
