Definitions

  • the present invention relates to a mast for dinghies, sailboats and sailing vessels of any kind, which consists of two laterally spaced, transversely arched to the longitudinal axis outwardly arched or straight mast halves that run together at or below the mast head and on the or reach directly above the mast base, the largest constructive width, the center between the mast halves extending Stag or the luff of the sail creates a vertical tension and transversely between the mast halves spokes carry the transverse forces through the arrangement and number of the dimensional stability of this construction and its static advantage is reached.
  • the execution of the mast profiles preferably and known to have a streamlined shape.
  • Both the spreaders and the mast are subjected to pressure due to the wind forces and the prestressing forces of shrouds and saws.
  • mast and spreaders are as far as possible kept slim.
  • the mast in the usual design in relation to the resistance to buckling has a wide profile and high weight and by its placement in front of the sail, which is held with the luff in a mast track , which adversely affects the wind flow when the boat is on the wind.
  • the air flow enters the sail it comes to a stall and to leeward and leeward vortexes in the area behind the mast.
  • the invention is therefore based on the object to improve the statics by the design of a mast in the manner described above, as well as to take into account a positive flow behavior.
  • the forces resulting from the wind pressure and from the prestressing are transmitted in the form of tensile forces via the mast halves in the form of pressure forces and via spokes and a centrally located stag.
  • the static advantage of the design according to the invention results from the loaded on tensile forces and thus in relation to their slenderness significantly higher loadable spokes. As well as due to the frequency of the arrangement of the spokes or the pressure elements given better distribution of forces over the entire length of the mast halves. Due to the design according to the invention results in a higher stability of the mast in relation to its weight.
  • the half-males are straight or partially straight and the inclination to buckling in a certain direction in this case is due to the asymmetrical (internal) material tensions, respectively in the direction of the convex side of the profile (open, semicircular) profiles of the mash halves and it can be avoided by appropriate arrangement of spokes or pressure elements, in proportion to their frequency, a buckling.
  • the internal spokes drove due to their small, round or flat elliptical cross section to no significant turbulence or air resistance values.
  • the sail can be mounted on the central stag or be hooked in the spokes over the length of the luffing frame in lighter spokes (small dinghies) or can also run freely between the mast top and the mast base (design without central stag).
  • the introduction of the lateral Wmd within the hull of the boat takes place either directly on the mast base mounted on the deck or in addition via shrouds, which in turn can attack deeply lying in the amount of Segelschwe ⁇ unktes on the inner Stag, resulting in a further weight reduction of the entire rig and result in a not insignificant reduction in the center of gravity of the mast and rig.
  • a boat in front view the design of a mast according to the invention of the two mast halves 1, the inner layer 2, which is positively connected to the bow ends 4 and 5 with the mast base and the curved mast halves vertically in Longitudinal span spans.
  • the spokes 3 provide for the tension of the mast halves to each other, transversely and obliquely to the longitudinal axis.
  • Optional shrouds 6 additionally introduce the resulting forces into the hull 7.
  • Fig.2 and Fig.3 represent the profile shapes 8 and 9 of the mast halves in cross-section normal to the longitudinal axis of the mast.

Abstract

L'invention concerne un mât pour véhicules à voile divisé dans le sens latéral en deux profils de mât (moitiés de mât) (1) symétriques, réunis sur ou sous le haut du mât, espacés sur la base du mât, courbés vers l'extérieur en forme d'arc ou s'étendant en ligne droite, le transfert des forces actives s'effectuant par l'intermédiaire d'un étai intérieur (2) et de branches intérieures (3) dont la disposition et le nombre permettent d'obtenir la stabilité de forme et l'avantage statique de cette construction. La division du mât en deux profils permet d'obtenir une amenée directe de la grand-voile (10), la réalisation des moitiés de mât et de leur forme de profil (8), (9) s'effectuant de préférence de manière aérodynamique.
