However, most of the forces arising during use and acting on the fabric 14 are taken care of not by the bolts 40 but by the cords 34 inside the fabric 14.
  • Figure lb shows the attachment of the side shield is shown in greater detail. Although the enlargement only concerns the lower attachment point 30, the construction of the upper attachment point 32 is similar in its basic principle. The angle of the attachment point 32 relative to the vertical portion of the boat's side can vary considerably, according to construction of boat. In addition the contact surface area between the boat's side 24 and side shield 10 can vary consider- ably according to different types of boat.

  • Natural-rubber-based Hypalon fabric for example, or some other fabric material that is sufficiently durable for the purpose, can be used as the fabric material in the side shield.
  • the material inside the elastic structure of the side shield can be preferably foam plastic. Foam plastic has closed cells, so that if it is wetted it does not absorb water, which would lead to a great additional weight for the side shield.
  • the cellular structure of foam plastic contains a large amount of air space, which improves its buoyancy and reduces weight.
  • the structure of a side shield manufactured from foam plastic means that the puncturing of the surface material will have practically no effect on the load-bearing capacity of the side shield, unlike traditional air-filled side shields.
  • the elastic struc- ture used in the side shield can also be of some other material suitable for the purpose, which does not absorb water into itself.
  • the elastic structure of the side shield according to the invention can also consist of several different materials. The different materials can have, for example, different elas- ticities, which will affect the properties of the side shield. The different materials can form different zones inside the side shield, which have mutually differing properties.

  • attachment plate 38 is tightened against the side of the boat, so that the fabric 14 remains in mechanical compression between the attachment plate 38 and the side of the boat. The fabric will then remain between the attachment plate and the side of the boat mostly with the aid of friction.
  • Each attachment plate covers the entire length of the side shield, i.e. it is continuous over the entire length of the side shield. So that excessive force will not be directed through the bolts to the holes in the fabric, there is a cord running inside the fabric, parallel to the longitudinal direction of the side shield.
  • the open fabric runs doubled between the attachment plate and the boat's side, so that the unified fabric forms a closed pleat 36 outside the attachment point, which is the loop 36 in the cross-sectional image according to Figure lb.

  • the relation of the length S to the height H can vary between the attachment points, for example, at attachment point 30 the relation can be 12 %, whereas at attachment point 32 the relation can be 15 % .
  • a sufficiently large contact surface area will ensure sufficient friction at the attachment points between the fabric and the attachment plates and the side of the boat. Differing from the figures, in some embodiments the number of pleats in the fabric can be two or more.
  • a continuous cord 34 runs longitudinally along the pleat 36.
  • the cord 34 is glued between the double-folded fabric, at the fold.

  • two pleats 36 are preferably formed, because both open ends of the fabric 14 are pleated at the attachment point 32.
  • Cords 34 are also placed in both pleats 36.
  • An air bag 28 is installed between the elastic structure 26 and the side 24 of the boat. In the air bag is a connection, with a valve at the end of it, to the inside of the boat. With the aid of this, the air bag is filled in connection with the installation of the side shield, so that the fabric becomes tight and crease-free, according to Figure 2.
  • the tensioning prevents movement of the elastic structure inside the fabric during sailing or under strain.
  • the air bag can be attached to the side of the boat, for example, by gluing. The location of the air bag between the boat's side and the elastic structure facilitates the manufacture of the elastic structure considerably. In addition, the maintenance of the air bag will be easier when required.
  • the overall elasticity of the side shield can also be adjusted with the aid of the degree of filling of the air bag, by adding air to, or letting it out of the air bag.
  • the main vertical shape of the cross-section of the side shield is that of the gunwale, so that it does not take up as much space laterally as the round shape according to the prior art. Thus, the boat's deck space is saved for other purposes.

  • the shape of the cross-section of the side shield can deviate considerably, but its main shape is always rectangular in the vertical direction. The possibility for many different shapes of cross-section also provides freedom for boat-specific design.

  • the higher stern part is intended to improve the buoyancy of the boat and through that its operational reliability in emergencies.
  • the side shield will float the boat. Thanks to the higher stern part of the side shield, the boat's engines will then remain above the water surface, so that when the boat is righted the engines will still be in operating condition. With the aid of this property, the boat can achieve a better Solas classification.
  • the side shield in displacement-hull boats the side shield comes above the water surface, or at least near to the water surface, so that in normal operating situations its buoyancy effect will be small. If the boat's hull is damaged, the side shield will be able to keep the boat afloat.

  • the side shield according to the invention can be used in all applications, in which there is a possibility to attach it.

Abstract

L'invention se rapporte à une protection latérale (10) pour un bateau (12) dans des situations de mise au sec et d'amarrage. La protection latérale selon l'invention comprend une structure élastique (26) configurée de façon à être placée à l'extérieur dudit bateau (12), sur le côté (24) du bateau (12), dans le but d'atténuer une énergie d'impact. La protection comprend aussi un tissu (14) placé sur le dessus de la structure élastique (26) pour maintenir la structure élastique (26) en position, ledit tissu (14) étant par ailleurs configuré de façon à être attaché au dit côté (24) du bateau (12) avec l'aide d'au moins une corde (34) appartenant à la protection latérale (10) depuis au moins un point de fixation (30, 32). Le tissu (14) est placé en double de sorte à former au moins un pli (36) parallèle à la direction longitudinale de la protection latérale (10) à au moins un desdits points de fixation (30, 32). En outre, chacune desdites cordes (34) est agencée à l'intérieur de chacun desdits plis (36), dans le sens longitudinal, de sorte à bloquer le pli à chaque point de fixation (30, 32) et à distribuer la contrainte uniformément sur le tissu (14), avec l'aide de chaque pli (36) et de chaque corde (34).
