Abstract

PURPOSE:To open a cleavage upon furling of a sail to expose a mast so that the furing of the sail is simplified, by forming the cleavage in a cylindrical section from the lower end to the top section of the cylindrical section. CONSTITUTION:The top end of a cylindrical section 2 formed in the rough 11 of a sail 1 is opened so that a top end opening 24 is formed, and a cleavage 25 is formed in the cylinder section 2 on one side of the cylindrical section in a radial direction. Further, there is provided a coupling means 3 or a slide fastener for opening and closing the cleavage 25. When the sail is furled, the slider 33 of the coupling means 3 is drawn up while a sail halyard 14 is slacked, to open the top end opening 24 so that, when the sail 1 is drawn down while a mast A is exposed, the sail is directly drawn right down. Further, furling ropes 16, 17 which are threaded through leaf clingles 15, 15 are attached to a boom C so that the furling of the sail may be rapidly carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a yacht sail support structure in which a cylindrical portion is provided in the luff, and a mast can be accessed by passing the mast through the cylindrical portion.

``Prior Art'' Conventional sail support structures for sailboats are shown in, for example, Figures 1 to 3, as can be seen in the catalog published by Yamaha Motor Co., Ltd. There is something like the one shown in the figure.

That is, a cylindrical part (2) is formed on the luff (11) which is the front edge of the sail (1), and the upper end of the cylindrical part (2)
1), and its cylindrical part (22) has no cracks and is bag-shaped, and the mast (A) is inserted through the opening (23) at the top end to support the sail (1). It is configured, and when you get the sale (1), you can move the square I・(
The same goes for removing the sail (1) by inserting the tip of the mast (A) through the 1-1 opening (23) by folding A). Must have (
A) was rotated and the sail (1) was wrapped around it.

However, with such conventional sail support structures,
The upper end of the cylindrical part (22) of the cylindrical part (2) is closed with the cap (21), and the sail (1) cannot be pulled straight down directly, so rotate the mass (A). Not only is it time consuming and dangerous to operate the sail, but when the sail is furled, the sail (1) is biased against the mast (A), creating a vortex (B) behind the mast (A) as shown in Figure 3. ◇ ``Purpose of the Invention'' The present invention was created by focusing on these conventional problems, and although it has a structure in which a cylindrical part is provided in the luff of the sail and the mast is inserted through it, the sail can be lowered straight down to make it easier to fold the sail. The purpose is to solve problem 1 by preventing the sail from being biased against the mast.

"Structure of the Invention" In order to achieve the above object, in the present invention, the upper end of the cylindrical part of the sail is open, and the upper end of the cylindrical part is opened on the - side of the radial direction from the lower end of the cylindrical part. This sail support structure is characterized by forming a crack across the length of the sail, and providing a connecting means for opening and closing the crack. ''It is made to be able to protrude from the two wheels, and when the sail is being hoisted, the mast can be protruded by listening to the cracks, making it easier to hoist the sail.

"Embodiments" Various embodiments of the present invention will be described below based on the drawings. Note that the same reference numerals as in the conventional example will be used for fH1i, and redundant explanation will be omitted.

Figures 4 to 7 show the first embodiment of the present invention in 71 pages, in which the cylindrical part (2
)' two wheels are opened to open an upper end opening (24) and a crack (25) is formed on one side of the radial direction of the cylindrical part (2), and the crack (25) which is a slide fastener is opened and closed. Coupling means (3) are provided.

The coupling means (3) is connected to a fastener part (31) having engaging W claws on both sides along the crack (25) and "1" between one end.
It consists of a detachable engagement part (32) at one end that opens and closes the crack 1j (25) at position 24) and a slider (33) that engages and disengages the fastener part (31). When the control (12), which is the do side of the sail (1), is stretched -1=-, the ice lamp (12a) and the rear end (12b) fixed to the boom (C) C'l) and (c2) with ropes, and a sail halyard (14) is connected to the peak (13) which is the upper end of the sail (1).
The sail barrier (14) enters the inside of the mast (A) via a pulley (At) fixed to the mast (A), hangs downward, and is fixed to the end of the mast (A). The cleat (A2) is pulled out from the vicinity of the cleat (A2).
2) It can be fixed by wrapping it around.

In the middle of the sail (1), there are leaf cringles (+5), (15), which are holes for the rope to be inserted during sail tightening.
・ is provided.

-j In the sail support structure of a yacht having the following configuration, when raising the sail (1), there is no need to align the mast (, A), and the slider (33) of the coupling means (3) -1
Move the end to the detachable engaging part (32) and attach the fastener part (31).
) and separate the upper end attachment/detachment retaining part (32),
After opening the crack (25), wrap the mast (A) in the second part of the cylindrical part (22), connect the upper end detachable engaging part (32) into one body, and then pull down the slider (33). At the same time, if you connect the sail barrier 1'' (14) to the peak (13) and pull the sail halyard (14) from below near Cree I (A2), the state shown in Figure 5 will be obtained, and the sail halyard ( 14) and move the slider (33) to i+i.
When the sail (1) is pulled down to the end of the 1st seam (25), the sail (1) can be pulled up and stretched as shown in Figure 4.

When retracting the sail, pull the slider (33) of the coupling means (3) while loosening the sail halyard (u), open the opening (24) at one end, and lower the sail (1) while letting the mast (A) protrude. ) can be pulled directly into the sail, and the furling rope (113) is attached to the reef cringle (15), (15) in an appropriate position as shown in Figure 6.

(17) is inserted and fixed to the boom (C), the sail can be quickly retracted. Since the sail (1) is not biased against the mast (A), as shown in Figure 7, when the sail is retracted, a large depression is created on the back of the mass I (A).
The air flow is not disturbed, the efficiency of the sail (1) is not extremely reduced, and sailing is not hindered.

In this embodiment, the coupling means (3) is -811 and IJ (25)
Since it is provided over the entire length from the -1 end to the upper end, there is an advantage that the sail (1) can be pitched without lowering the mast (A).

Figure 8 shows a second embodiment, in which a pulley (A3) is provided to guide the sail halyard (14) that pulls up the peak (13) of the sail (1) to the outer surface of the mast (A). ,
The sail halyard (14) is suspended from the crease (A2) at the top end of the mast (A) without passing it through the inside of the mast (A).

According to this embodiment, the sail halyard (14) is massed)
Since it does not pass through the inside of (A), it has the advantage that the structure of (A) can be simplified.

FIG. 9 shows a third embodiment, in which the crack (25) is provided only in the lower part of the cylindrical part (2).

In this embodiment, although it is difficult to raise the sail (1) without collapsing the mast (A), there is no problem in hoisting the sail, and the crack (25) is connected to the connecting means (3). ) can be kept to a minimum and the cost amplifier can be suppressed.

In each of the above embodiments, a slide fastener was used as the connecting means (3) for opening and closing the crack (25), but fasteners, buttons, so-called Velcro fasteners, and even sewing the rope to the crack (25) were used as the connecting means (3). ) Various types of connection methods can be used, such as erecting the bridge.

"Effects of the Invention" According to the sail support structure for a yacht according to the present invention, a crack is provided in the cylindrical part of the sail, and a coupling means is arranged therein to make it possible to open and close the sail without wrapping it around the mast. This makes it extremely easy to furlough the sail, and when furled, the sail is not biased against the mast, which stabilizes the air flow and dramatically reduces the efficiency of the sail. A sail support structure for a yacht that is safe and efficient can be achieved without causing the sail to sag.
