AI Technical Summary

Technical Problem

Existing sail storage devices fail to smoothly raise the sail when a lateral force acts on the sail due to wind, causing the batten to get caught in the mesh of the net body.

Method used

A batten guide device with a batten guide rope connecting the boom holding rope and the boom, sandwiching the inner side of the batten from both sides parallel to the mast, preventing the batten from getting caught during sail raising.

Benefits of technology

The device allows the sail to be raised without the batten getting caught, even when a lateral force acts on the sail due to wind.

Abstract

To provide a batten guide device for a sail capable of hoisting the sail without having the batten being caught even when lateral force is working on the sail by the wind when hoisting or bringing down the sail.SOLUTION: A sail 5 is capable of being hoisted without having a batten 4 attached to the sail 5 being caught by batten guide ropes 6 since the batten guide ropes 6 are attached to hold the inner side from a rear end unit of the batten 4 from both the right and the left to be almost in parallel with a mast even when lateral force is working on the sail by the wind when the sail 5 is being hoisted.SELECTED DRAWING: Figure 2

Description

Technical Field

[0001] The present invention relates to a batten guide device for a sail.

Background Art

[0002] Conventionally, when lowering a sail, even if a lateral force acts on the sail due to wind, the sail guide, which is entirely composed of a net body, prevents the sail from protruding to the side of the boom, and the sail can be smoothly stored on the boom. There is known a sail storage device (see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the sail storage device of Patent Document 1, when raising the sail, if a lateral force acts on the sail due to wind, the tip of the batten, which is shorter than the sail guide, gets caught in the mesh of the sail guide, which is entirely composed of a net body, and there is a problem that the sail cannot be smoothly raised. An object of the present invention is to provide a batten guide device for a sail that can pull up the sail without the batten getting caught even when a lateral force acts on the sail due to wind when raising the sail.

Means for Solving the Problems

[0005] As a means for solving the above problems, the batten guide device for a sail of the present invention is a yacht including a mast, a boom attached to the lower side of the mast, a boom holding rope extending from the tip of the mast and holding the rear end of the boom, and a sail to which a batten is attached, characterized in that a batten guide rope connecting the boom holding rope and the boom is attached so as to sandwich the inner side of the rear end of the batten from both the left and right sides substantially parallel to the mast.

Effect of the Invention

[0006] According to the present invention, when raising the sail, even when a lateral force acts on the sail due to the wind, the sail can be pulled up without the batten getting caught.

Embodiment for Carrying Out the Invention

[0008] An embodiment of the batten guide device for a sail according to the present invention will be described with reference to the drawings, but it is not limited to only the embodiments described below. FIG. 1 is a side view showing a batten guide device for a sail in a state where the sail is lowered. On both the left and right sides of the boom 2, batten guide rope boom attachment portions 7 are respectively provided inside the rear ends of the battens 4 attached to the sail 5, and left and right batten guide ropes 6 extending upward substantially parallel to the mast 1 from the respective batten guide rope boom attachment portions 7 are connected to batten guide rope boom holding rope connection portions 8 provided on the boom holding rope 3.

[0009] FIG. 2 is a side view showing a batten guide device for a sail in a state where the sail is raised. When listing Sale 5, even when a lateral force acts on the sail due to the wind, since the batten guide ropes 6 are attached so as to sandwich the inner side of the rear end portion of the batten 4 from both the left and right sides substantially parallel to the mast, the batten 4 attached to the sail 5 can pull up the sail 5 without getting caught on the batten guide ropes 6.

Claims

【Claim 1】 In a yacht comprising a mast, a boom attached below the mast, a boom retaining cable extending from the tip of the mast and holding the rear end of the boom, and a sail to which battens are attached, a batten guide cable connecting the boom retaining cable and the boom is attached so as to sandwich the inside of the rear end of the batten from both the left and right sides substantially parallel to the mast. A batten guide device for the sail, characterized in that.
