Mast for sailing vehicles

Abstract

Described is a mast for sailing vehicles being divided in a lateral direction into two mirror symmetrical mast profiles (mast halves) ( 1 ), which merge at or under the top of the mast, which are placed apart on the base of the mast, and which are curved outward to form arcs or run in a straight manner, wherein the acting forces are transferred via an inner stay ( 2 ) and inner spokes ( 3 ), so that the stability of the construction is achieved with their arrangement and number and static advantage is achieved. A direct flow onto the mainsail ( 10 ) is enabled by the division of the mast into two profiles, wherein the design of the mast halves and the profile shape thereof ( 8 ), ( 9 ) are preferably carried out in an aerodynamic manner.

1 . Mast for a sailing vehicle, characterized in that a division of the mast in a lateral direction results in two mirror-image mast halves, which merge at a mast top and are apart from one another at a mast base, forming curved or straight mast halves ( 1 ), and the transfer of acting forces takes place through an inner stay ( 2 ) and inner spokes ( 3 ). 
     
     
         2 . The mast according to  claim 1 , characterized in that a design and an arrangement of the mast halves and its profile form is carried out in a streamlined form. 
     
     
         3 . The mast according to  claim 1 , characterized in that the mast halves are in each case provided with a straight or a partially straight design, and that they merge inclined to each other at the mast top or below the mast top. 
     
     
         4 . The mast according to  claim 1 , characterized in that instead of the stay ( 2 ), the luff of the main sail transfers vertical tension with a simpler construction. 
     
     
         5 . The mast according to  claim 1 , characterized in that the central stay is provided with a guide rail for accommodation of the mast slider (of the luff). 
     
     
         6 . The mast according to  claim 1 , characterized in that the profile ( 8 ) of the mast halves is maintained open for a light design and provided with a light material or sail canvas inside a covering ( 11 ). ( FIG. 2 ) 
     
     
         7 . The mast according to  claim 1 , characterized in that each (open) profile of the mast halves faces with its concave side outward, and that the mast halves are supported and connected to each other by pressure elements. 
     
     
         8 . The mast according to  claim 1 , characterized in that a strip of canvas is mounted in order to improve wind guidance and to enlarge a sail area, respectively, on rear edges throughout an entire length of the mast halves. 
     
     
         9 . The mast according to  claim 1 , characterized in that adjustable guide profiles are mounted in order to improve wind guidance throughout an entire length of the mast halves. 
     
     
         10 . The mast according to  claim 1 , characterized in that a profile ( 9 ) of the mast halves is designed in a streamlined and high-strength form as a strutted hollow profile. 
     
     
         11 . The mast according to  claim 1 , characterized in that the mast is mounted in a fixed manner on a boat body and that resulting forces are introduced directly through a mast base ( 5 ) into a hull. 
     
     
         12 . The mast according to  claim 1 , characterized in that the mast is mounted rotatably. 
     
     
         13 . The mast according to  claim 1 , characterized in that the mast is mounted pivotably. 
     
     
         14 . The mast according to  claim 1 , characterized in that the mast is mounted rotatably and pivotably. 
     
     
         15 . The mast according to  claim 1 , characterized in that when a rotatable (and pivotable) execution is used, the beam is firmly connected to a mast construction and it swivels during a rotation. 
     
     
         16 . The mast according to  claim 1 , characterized in that a design of the mast halves is realized by an aluminum extruded profile or by carbon materials and laminates. 
     
     
         17 . The mast according to  claim 1 , characterized in that a design is realized by (plastic/carbon) laminates in a composite construction. 
     
     
         18 . The mast according to  claim 1 , characterized in that a design of spokes is realized in a simple construction as a round profile, with wire or rope articles having an optimal construction as a streamlined flat material manufactured from steel carbon materials/laminates or from plastic materials. 
     
     
         19 . The mast according to  claim 1 , characterized in that pressure elements are additionally attached to spokes between the mast halves for high and varying loads.
