Abstract

PURPOSE:To make furling, unfurling and turning operations on two lengthwise and crosswise sails ever so easy, by making these sails turnable simultaneously with operation of a turning rope in a way of using the rotary shaft installed along a mast in common. CONSTITUTION:A rotary shaft 2 extending in vertical directions is rotatably supported by both upper and lower receiving blocks 3 and 4 installed in a mast 1a. And, on this rotary shaft 2, a support block 5 is locked as having it situated in just below the upper receiving block 3 while a power box 6 is also locked as having it situated just above the lower receiving block 5, respectively. In addition, an upper boom 7 for horizontal sail use is projectingly installed in the support block 5, while a lower boom 8 for horizontal sail use is rotatably supported on the power box 6, and a boom 9 for vertical sail use is attached to the poer box 6 in a state of being locked. And, the other end of a turning rope 12, whose one end is connected to both tip ends of the horizontal sail upper boom 7, is connected to an expansion machine 13. Then, when the turning rope 12 operates for expansion or contraction motion, these horizontal sail upper and lower booms 7 and 8 and the vertical sail boom 9 all turn round simultaneously.

Description

[Detailed description of the invention]

[Industrial Application Field 1] The present invention relates to a sailing device for a sailing ship equipped with vertical sails and horizontal sails. [Prior Art] Sailing ships equipped with vertical sails and horizontal sails have been known for a long time, but the expansion and contraction of the sails and turning operations are performed manually, and sailing ships equipped with power-driven sailing devices have been known for a long time. The ship is equipped with either vertical sails or horizontal sails, and there is no known sailing ship equipped with a power-driven sailing device that allows the sails to be freely extended and retracted and to turn both vertically and horizontally.

[Problem to be solved by the invention 1] If the sailboat is only equipped with either vertical sails or horizontal sails, there is a problem that the range of use of the sailboat will be limited depending on the wind direction angle, and the sailboat must always maintain stable sailing. It was difficult to expect this, and there was a demand for a sailing ship equipped with a sailing device that could freely deploy and retract the vertical and horizontal sails and turn without relying on direct manual operation. [Means for Solving the Problems] The present invention has been made in view of the above points, and its purpose is to assemble both vertical and horizontal sails on one rotating shaft,
To provide a sail rigging device for a sailing ship that can perform the turning operation at the same time and can extend and retract the vertical sail and the horizontal sail separately. Therefore, the above-mentioned object of the present invention is to rotatably support a rotating shaft extending in the vertical direction on a mast, fix a support stand and a power box at the upper and lower positions of this rotating shaft, and have the support stand oriented in the left-right direction. At the same time, an upper boom for side sails is provided protrudingly provided, and one end of a slewing cable that is connected to each telescoping machine and extends and contracts in opposite directions is connected to both ends of the upper boom for side sails, and the above-mentioned power box is connected to the power box. A lower boom for side sails is rotatably attached in correspondence with the upper boom for side sails, and a boom for vertical sails is protruded orthogonally to the lower boom for side sails, and the upper boom for side sails and the upper boom for side sails are connected to each other. A horizontal sail that can be retracted onto the lower boom is supported between the lower boom and the lower boom for the horizontal sail is connected to a first motor provided in the power box, while The upper end side of the vertical sail is supported on the support base, and the lower end side of the vertical sail is expanded and retracted onto the vertical sail boom via a traveling body that is attached vertically to the vertical sail boom and is freely movable. This is accomplished by a sailing device for a sailing ship, which can be freely mounted, and the traveling body is provided in the power box and coupled to a second motor.

In this case, a drum 22 is fixed on the lower boom 8 for side sails coaxially with the boom 8,
Both end portions 22a of this drum 22 function as auxiliary drum parts around which the support rope 17 is wound, and when the lower side sail boom 8 is rotated in forward and reverse directions by power means to be described later, the support rope 17 and the winding rope are By the reeling and reeling action opposite to that of the sail 18, the side sail 16 can be reeled into and unwound onto the drum 22 to be expanded and retracted. Further, the vertical sail 23 is stretched between the support base 5 and the vertical sail boom 9, and its upper end portion is supported on the support base 5 by a plurality of upper connecting ropes 24, and its lower end portion is supported by a plurality of lower connecting cables 24. It is supported by a running body 26 by a connecting cable 25. The traveling body 26 is provided vertically along the vertical sail boom 9 so as to be freely movable, and the lower connecting cable 25a located at the forefront of the lower connecting cables 25 is attached to the traveling body 26, and the lower connecting cable 25a located at the rearmost part of the lower connecting cable 25 The connecting cables 25b are connected to the power box 6 using fixing fittings 27 and 28, respectively, and the intermediate lower connecting cable 25 is connected to the traveling body 26 using a ring 29 so that it can freely slide relative to the running body 26. There is. Therefore, the traveling body 2 is
6 travels back and forth, the vertical sail 23 can be expanded and contracted along the vertical sail boom 9. In the case shown in Figure 1, a deployment cable is used as the traveling body 26, and the deployment cable is connected to a pulley 31 supported on one side of the boom 9 for vertical sails and a power box 6. The hook is passed between the drive drum and the drive drum provided inside, and both ends of the hook are connected to different positions on the drive drum after being wrapped around the drive drum, and the hook can be used in the forward or reverse direction of the drive drum.
