(54) СКЛАДНАЯ МАЧТА ПАРУСНОГО СУДНА(54) FOLDING MAST OF A SAILING SHIP

1one

Изобретение относитс к парусным судам в частности к конструкци м мачт.The invention relates to sailing vessels, in particular to structures of masts.

Известна складна мачта парусного судна , содержаща -нижнюю часть и соединенную с ней иУарнирно верхнюю часть с приводом дл ее поворота, включающим несущее стержневое звено и сто щий такелаж 1.The folding mast of a sailing vessel is known, comprising a lower part and an upper part connected to it and the upper part with a drive for turning it, including a supporting pivot link and standing rigging 1.

Недостатком известной складной мачты вл етс то, что верхн часть мачты имеет значительную длину, в результате чего при заваливании мачты она имеет большие деформации, что приводит к трудоемким и небезопасным операци м, св занным с установкой мачты. Кроме этого, указанный недостаток ограличивает применение известной мачты на крупных судах.A disadvantage of the known folding mast is that the upper part of the mast is of considerable length, as a result of which, when the mast is collapsed, it has large deformations, which leads to time-consuming and unsafe operations associated with the installation of the mast. In addition, this drawback restricts the use of a known mast on large vessels.

Целью изобретени вл етс снижение массы, обеспечение безопасности и облегчение работ при заваливании мачты.The aim of the invention is to reduce weight, ensure safety and facilitate the work when the mast is collapsed.

Указанна цель достигаетс тем, что мачта снабжена опорой с тросом, причем верхний конец несущего стержневого звена щарнирно св зан с верхней частью мачты , а его нижний конец соединен шарнирн.о с опорой, установленной с возможностью скольжени вдоль нижней части мачты.This goal is achieved in that the mast is provided with a support with a cable, with the upper end of the supporting rod link being hinged to the upper part of the mast, and its lower end is connected by a hinge with a support installed with the possibility of sliding along the lower part of the mast.

причем трос опоры св зан с приводом, расположенным вдоль мачты.wherein the support cable is connected to a drive located along the mast.

На фиг. 1 изображено парусное судно со складной мачтой; на фиг. 2 - то же, вид с кормы.FIG. 1 depicts a sailing vessel with a collapsible mast; in fig. 2 - the same view from the stern.

The folding mast is held by the rigging 9.

Claims

15, the upper part of the mast 3 rises forward to the bow of the vessel and loads the supporting pivot link 5 connected with it by a hinge 4. The declination of the upper part 3 comes along with the lowering of the lower support 7 held by the cable 8 along the mast. to the required position, the overall height of the vessel is reduced and the vessel can pass under a bridge of an appropriate height. If, however, it is necessary to pass under a very low bridge, then in this case a second operation is carried out to incline the mast I, already aft in the usual order. The restoration of the upper part of the 3 masts is performed in the reverse order. The use of the invention makes it possible to significantly simplify the process of lowering the mast, eliminate hand and unsafe labor, ensure passage under the bridge under small sails, and shorten the duration of the entire voyage. Claims The folding mast of the ship's parasol contains the lower part and the upper part connected to it pivotally with a drive for its rotation, including a supporting pivot link and stand rigging, characterized in that, in order to reduce weight, ensure safety and facilitate work when rolling up mast, it is provided with a support from the troso.m, the upper end of the supporting rod link is hinged to the upper part of the mast, and its lower end is pivotally connected to the support installed with the possibility of sliding along the lower part mast, wherein the support cable is coupled to the drive raspolozhenny.m along the mast.
