Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for facilitating lifting (sail-up) of a sail from the water surface when the windsurfing sail falls to the water surface.
[0002]
[Prior art and problems to be solved by the invention]
When enjoying windsurfing on the water, the sail often falls to the surface due to being hit by a strong wind or making an operational error. Especially for beginners who are unskilled in operating techniques, this can happen at a fairly high frequency. Therefore, as shown in FIG. 1, one end of the rope 13 is connected to the control tool (boom) 11 integrated with the sail 10 and the other end of the rope 13 is connected to the mast 12 in case the sail 10 falls to the surface of the water during navigation. The ends are fixed, and a suitable position of the rope 13 is grasped by hand, and sail-up is performed by pulling in an obliquely upward direction (arrow 15) with respect to the board. At this time, it is considered desirable to place both feet on the position 14 in order to balance the body.
[0003]
However, for a sail that has fallen to the surface of the water, in addition to the weight of the sail itself, water accumulates on the upper surface and the lower surface sticks to the water surface due to surface tension. Sustainability that lasts for hours is required. Therefore, the reality is that it is a very difficult task for people and women who do not have enough strength, especially because the enthusiasm for windsurfing is diminished when faced frequently at the beginner's stage. It has also become a cause to hinder.
[0004]
An invention for solving such difficulty in sail-up is described in Japanese Patent Application Laid-Open No. 2000-177690. According to the present invention, a hole is made in a sail, and a cover for securing lift and allowing water to flow out in a certain direction is attached to the hole. However, drilling a hole in a sail is fatal in terms of losing lift for windsurfing using the lift that acts on the sail, and even if a cover is attached to the hole, lift and design are still There is no change in that there is a problem.
[0005]
The present invention has been made to solve these problems, and the purpose of the present invention is to perform sail-up easily without opening a hole in a sail even by a person or a woman who does not have arm strength. It is to provide an apparatus for obtaining.
[0006]
[Means for Solving the Problems]
An apparatus for sail-up according to the present invention, which has been made to solve the above problems,
a) a rod-like member standing on the board;
b) a direction changing tool for passing through a rope fixed to the tip of the rod-shaped member, one end of which is fixed to the rig part;
It is characterized by providing. The “rig part” is a general term for a part (including a sail, a boom, a mast, etc.) above the board.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
In the sail-up device according to the present invention, first, a bar-like member is erected on the board. Next, a direction changing tool for passing through the rope is fixed to the tip of the rod-shaped member. Finally, a rope having one end fixed to the rig portion may be passed through the direction changing tool.
[0008]
Next, a method for using the sail-up device according to the present invention will be described. When the sail falls to the water surface, first, a rope having one end fixed to the rig is passed through a direction changing tool fixed to the tip of a rod-like member standing on the board. Next, the body is oriented so that it is perpendicular to the longitudinal direction of the board, both legs are spread to the width of the shoulder, and stands in front of the rod-like member on the board (position 23 in FIG. 2 is the position of both legs at this time). Is). Thereafter, the rope may be grasped by hand and pulled downward (arrow 26 in FIG. 2) in a direction substantially perpendicular to the board. At this time, in order to balance the body, the bar-shaped member may be grasped with a free hand.
[0009]
【The invention's effect】
When the device for sail-up according to the present invention is used, the rope is pulled downward substantially parallel to the bar-like member erected on the board, so that the rope is pulled obliquely upward with respect to the board as in the conventional case. Therefore, it is easy to put effort into it, so even people and women without strength can easily sail up. In addition, since a downward force is exerted in a direction substantially perpendicular to the board, it is possible to stabilize the unstable board on the water surface and to make sailing easier.
[0010]
Furthermore, when tired during sail-up, the work can be performed while taking a break by grasping the rod-shaped member. Of course, as mentioned above, you may hold it from the beginning to balance your body.
[0011]
Also, when pulling the rope diagonally upward with respect to the board as in the past, it is difficult to balance the body on the board because the direction of the body is parallel to the longitudinal direction of the board (see FIG. 1). Falling into the water (referred to as “sink”) can occur frequently, especially for beginners. However, when the sail-up device according to the present invention is used, the body can be oriented perpendicular to the longitudinal direction of the board (see FIG. 2), so that the body can be easily balanced by opening both feet to the shoulder width. And therefore less likely to accidentally fall into the water during sail-up.
[0012]
【Example】
A first embodiment of a sail-up device according to the present invention will be described. FIG. 2 is a perspective view of windsurfing equipped with the sail-up device of the present embodiment. On the board 20, a base 22 necessary for standing the rod-like member 21 is placed. An enlarged view of the base 22 is shown in FIG.
[0013]
A tubular member (hereinafter referred to as “base tubular member”) 222 having a diameter slightly larger than that of the rod-like member 21 is fixed to the plate-like member 221 constituting the base 22. The plate-like member 221 is rectangular in FIG. 3, but of course, various shapes such as a circle and an ellipse are conceivable. The material used for the plate-like member 221 and the base tubular member 222 may be anything as long as it is lightweight so as not to impair the buoyancy of the board 20 while maintaining the necessary strength (for example, a light metal such as aluminum or plastic). The base 22 is fixed on the board 20 by a belt 223. The belt 223 may be fixed on the board 20 by, for example, attaching the fastener 224 to an appropriate position of the belt 223 and fitting the concave portion and the convex portion of the fastener 224, or by hooking. This may be done by attaching to one end of the belt 223.
[0014]
Next, the rod-like member 21 is inserted into the base tubular member 222 fixed to the plate-like member 221. In this case, by making the diameter of the rod-shaped member 21 substantially the same as the inner diameter of the base tubular member 222, it is possible to prevent the rod-shaped member 21 from dropping from the base tubular member 222 during sail-up. In addition, about the diameter of the said rod-shaped member 21, although depending on the intensity | strength of the material to be used, about 20-50 mm is desirable, for example, in the case of an aluminum pipe. The length is preferably between the user's waist and height from the viewpoint of convenience in use and hindrance to navigation, and further, the boom position at the time of sail-up completion (this is It is most desirable that the height of the user is usually about the height of the chest.
[0015]
As another specification, the rod-shaped member 21 may be inserted into the base tubular member 222 fixed directly to the board 20. As yet another specification, a rod-shaped member 21 may be connected to a joint attached to the board 20 or the plate-shaped member 221 so that the rod-shaped member 21 can be moved in any direction 360 degrees. However, in this case, it is necessary to provide means for fixing the rod-like member 21 in a state where the rod-like member 21 is erected vertically.
[0016]
Subsequently, a ring 25 a as shown in FIG. 4A is fixed to the tip of the rod-shaped member 21 as the direction changing tool 25. Thereafter, a rope having one end fixed to the rig portion may be pulled through the ring 25a. However, when the rope is wet with water, the friction generated between the inside of the ring 25a and the rope is increased, so that a large force may be required when pulling the rope. Therefore, the friction may be reduced by bonding a low friction member (for example, a bead) along the inside of the ring 25a.
[0017]
As another specification of the direction changer fixed to the tip of the rod-shaped member 21, a direction changer 25b including four spheres 251b arranged in two upper and lower stages as shown in FIG. 4B may be used. Good. The four spheres 251b are pierced rotatably by two coaxials 252b. The rope having one end fixed to the rig portion is pulled through the gap 253b formed by the four spheres 251b. As a result, when the rope is pulled, the 1 to 4 spheres 251b that are in contact with the rope also rotate around the shaft 252b at the same time, so that even if the rope is wet with water, the rope is pulled by friction. There is no need for great power. In addition, about the magnitude | size of the clearance gap 253b, it is good to set it as the grade which is substantially the same as the diameter of a rope, or slightly large. This is because if the gap is too large, the rope will be caught in the groove between the spheres 251b, and conversely, the force for pulling the rope will increase.
[0018]
Furthermore, as another specification of the direction changer fixed to the tip of the rod-shaped member 21, a pulley 25c as shown in FIG. 4 (c) may be used.
[0019]
Regardless of which direction change tool described above is used, when the rope that has passed the direction change tool is directly gripped and pulled, the rope will reverse when the hand is released, so the rope will always remain until the sail is finished. Must be held by hand. However, considering the weight of the sail, this places a considerable burden on the hands and arms, so it is desirable to prevent the rope from reversing even if the rope is released during sail-up. Various forms, structures, and materials are conceivable as anti-reverse tools for achieving such an object, but an example is an “easy rig” used for sail setting. . FIG. 5 (a) is a perspective view of an example of an easy rig, and FIGS. 5 (b) and 5 (c) are a side view (b) and a plan view (c) of the same easy rig. The width of the groove of the easy rig 50 is gradually narrowed in the depth direction, and a plurality of irregularities 502 are alternately provided on the inner wall 501. By fitting the hand-drawn rope tightly into the groove of the easy rig 50, it is possible to prevent the rope from returning backward even if the gripped rope is released. The easy rig 50 may be fixed at an appropriate position of the rod-shaped member 21.
[0020]
In addition, when the rope that has passed the direction changing tool is directly grasped and pulled by the hand, the palm may be damaged by the rope or the arm may be fatigued. Therefore, as a second embodiment of the sail-up device according to the present invention, as shown in FIG. 6, a lever 60 capable of temporarily fixing the rope 24 at an appropriate position of the rod-like member 21 erected on the board 20 is provided. Attach and move the lever 60 up and down (arrow 61) to handle the rope 24.
[0021]
It should be noted that, similarly to the case where the rope is directly gripped by the hand and pulled, the above-described anti-reverse device such as the easy rig 50 may be used in this embodiment. It is desirable that the easy rig 50 is fixed at an appropriate position between the tip of the rod-shaped member 21 and the mounting position of the lever 60.
[0022]
Furthermore, as a third embodiment of the sail-up device according to the present invention, as shown in FIG. 7, a second embodiment is provided in which a rope gripping tool and a ratchet are provided below the board 20 or a rod-like member 21 erected on the board 20. The direction changer 70 is fixed, and the rope 24 having passed through the first direction changer 25 and the second direction changer 70 is pulled upward (arrow 71) substantially parallel to the rod-shaped member 21. Also good. According to the present embodiment, even if the hand is released by the action of the rope gripping tool and the ratchet, the rope 24 does not reverse.
[0023]
As another specification of the present embodiment, when a member connected to the release tab of the ratchet is placed on the board 20 and the board 20 is inclined at a certain angle or more during sail-up, the member moves over the board 20. The release tab of the ratchet may be operated by moving. As a result, the rope gripping tool and the ratchet are released, and the rope is free to come off. As a result, the inclination of the board 20 is eliminated, and the possibility that the operator accidentally falls into the water is reduced.
[0024]
In any of the first to third embodiments of the sail-up device according to the present invention, the foam member may be attached to an appropriate position (for example, a sail or a boom) of the rig part. This is because the ratio of the sail that has fallen to the water surface due to the buoyancy of the foam member decreases below the surface of the water, so that less force is required to pull the rope that has passed the direction changer.
[0025]
Furthermore, in any of the first to third embodiments of the sail-up device according to the present invention, the bar-like member is placed on the board except during sail-up so that the bar-like member standing on the board does not hinder navigation. It is better not to leave it standing. Therefore, for example, a storage space may be provided on the board so that the removed bar-shaped member can be stored therein.
