DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of setting a lane (course) for laying a course for practicing or competing (race) such as a canoe or rowing boat on water, and a lane for defining a lane
The present invention relates to a buoy mooring method and structure, and a lane rope used for lane setting.

[0002]

2. Description of the Related Art Lanes (courses) for canoeing, rowing boats, etc. are made as follows. 1.5 m depth at the place where the lane should be set (lake, pond, river, etc.)
It is stretched in parallel with several lane ropes at intervals of the width of the lane (about 9 to 12 m) in water. These lane ropes must be properly spaced (eg 20-25m
Lane buoy is moored. A lane is defined by a number of lane buoys floating on the water.

[0003] Conventional lane setting has been performed as follows.

[0004] In a factory, marking is performed at a position where the lane buoy of the lane rope is to be attached while the lane rope is tensioned in advance. The lane rope is wound around a reel (or a drum) and transported to the setting site of the lane.

[0005] One end of a lane rope is fixed to a winch installed on land, a reel around which the lane rope is wound is placed on a boat, and the boat is advanced along a path to which the lane rope is to be stretched. The worker on the boat rewinds the lane rope from the reel, attaches the rubber tube to the marked position, and wraps vinyl tape on it to secure the rubber tube to the lane rope. A snap clip is attached to the end of the buoy rope tied to the lane buoy, which represents the lane boundary. Attach this snap clip to the lane rope over the vinyl tape. Carry out the above procedure for each marking position while moving the boat. When the required number of lane buoys has been attached to one lane rope, place the lane rope at the specified water depth and anchor it. Stretch using.

At the site where the lane is set, as described above, while the lane rope is rewound, the rubber pipe is attached to the lane rope and the work is fixed with vinyl tape. There is a problem that it takes.

Further, the lane rope is tightly sandwiched from above the rubber tube with the snap clip. When the lane rope is rewound from the reel, the lane rope twists. Along with this, the clip fixed to the lane rope rotates, and the buoy rope tied to the clip becomes entangled with the lane rope. For this reason, after the lane rope was completely rewound, the work was required to correct the twist of the lane rope and loosen the entangled buoy rope.

[0008]

DISCLOSURE OF THE INVENTION An object of the present invention is to simplify the operation at the lane setting site as much as possible.

According to the lane setting method of the present invention, a pair of two positioning pieces are fixed to the lane rope at each location where a lane buoy is to be provided, with an interval enough to allow a connection fitting to be inserted therebetween. Keep it.

At the site, a detachable connecting bracket is loosely and rotatably mounted on the lane rope between a pair of positioning pieces while stretching the lane rope underwater in a place where a lane is to be set. , The buoy rope connected to the lane buoy is connected to the lane rope.

The lane rope is linearly stretched underwater, thereby setting a lane defined by a plurality of lane buoys moored along the lane rope.

The lane rope and the positioning piece are preferably made of stainless steel from the viewpoint of rust prevention.

[0013] The positioning piece is attached to the lane rope in advance at a factory. The lane rope to which the positioning piece is fixed is wound around a reel or the like and transported to the site.

At the site where a lane is to be set, a detachable connecting bracket is mounted between a pair of two positioning pieces while the lane rope is rewound from the reel. The connection fitting has a portion through which the lane rope passes, and there is a slight clearance between the inside of this portion and the outer periphery of the lane rope. Therefore, the connection fitting is rotatable with respect to the lane rope. The positioning piece is larger than the inside of the rope insertion portion of the connection fitting. Therefore, the connection fitting does not go out of the position between the two pieces. The lane buoy is moored by this connection fitting.

Since the positioning piece is fixed to the lane rope in advance, it is not necessary to mount a rubber tube or the like on site, as in the prior art.

[0016] Even if the lane rope is twisted when the lane rope is unwound from the reel to stretch the lane rope, the connecting bracket is rotatable with respect to the lane rope. The buoy rope connected to the lane buoy does not become entangled with the lane rope. As before,
There is no need to unravel the entangled buoy rope.

Both ends of the lane rope stretched underwater are fixed by anchors provided on land or underwater.

In a place where water flows, such as a river, it is difficult to take anchors in water. Therefore, it is advisable to stretch the lane rope by the following method using a horizontal rope.

One end of the horizontal rope is fixed on the land, and the horizontal rope is stretched diagonally or vertically to the waterside toward the water.

[0020] One end of the lane rope is fixed on land, and the lane rope is hung in the middle of the above-mentioned horizontal rope, and then the direction is changed so that the lane rope is linearly inserted into the water where the lane is to be set. Stretch.

According to this method, a lane is set by stretching a plurality of lane ropes so as to be parallel at intervals.

According to this method, at least one end, and in some cases, both ends of the horizontal rope and the lane rope can be fixed on land, so that the rope can be easily fixed.

The present invention also provides a method and structure for mooring a lane buoy.

According to the lane buoy mooring method, two pairs of positioning pieces are spaced apart from each other,
In addition, a fixed lane rope is prepared in advance for each predetermined length in which a lane buoy is to be provided.

The lane rope is stretched underwater in a place where a lane is to be set, and a detachable connecting bracket is loosely and rotatably mounted on the lane rope between a pair of positioning pieces. -Mooring the lane buoy by connecting the buoy rope connected to the buoy to the lane rope.

This lane / buoy mooring method also facilitates on-site work.

The lane buoy mooring structure according to the present invention is a structure made by the above method.

That is, in the mooring structure of the lane buoy, a lane rope is stretched underwater along the boundary of the lane to be set, and a plurality of pairs of the lane rope are spaced apart from each other at a predetermined interval. The positioning piece is fixed, there is a gap between the two positioning pieces in a pair, and a detachable connecting bracket can rotate on the lane rope in the gap between the two positioning pieces in a pair. And the lane buoy is moored by this connection fitting.

The present invention further provides a lane rope used in the above-described lane setting method, lane buoy mooring method and mooring structure.

In this lane rope, two pairs of positioning pieces are spaced apart from each other, and
The buoy is fixed at each position to be moored.

This lane rope is suitable for the method and structure described above.

[0032]

1 and 2 show lanes (courses) of canoeing, rowing boats, and the like set in a practice field such as canoeing and rowing boats provided in lakes, marshes, ponds, rivers, and the like.

A plurality of lanes are provided in water at a depth of about 1.5 m.
The ropes 10 are stretched linearly and parallel to one another at intervals. The end of the lane rope 10 is fixed to a fixed object on land or is moored underwater by an anchor. The interval between adjacent lane ropes 10 defines the width of lane 1, and is about 9 to 12 m.

The lane rope 10 includes a plurality of lane buoys.
40 are moored at appropriate intervals (eg, 20-25 m). That is, the lower end of the buoy rope 41 tied to the lane buoy 40 is tied to the connecting fitting 30, and the connecting fitting 30 is attached to the lane rope 10. In this way, lane buoys moored and arranged on the water
Lane 1 is formed by the arrangement of 40.

Preferably, the lane rope 10 and the connecting bracket 30
The positioning piece 20 described later is made of stainless steel. The buoy rope 41 is also made of stainless steel wire, plated steel wire, synthetic fiber, or hemp or other fibers.

FIGS. 3 and 4 show the structure of the connecting fitting 30 and the state in which the connecting fitting 30 is attached to the lane rope 10. FIG.
Is shown in

The connecting bracket 30 is made of a single elastic wire, and this wire has a hooked portion 31 at one end (this portion is referred to as a hooked portion). It advances and extends almost at a right angle (this portion is referred to as a spring portion 32). The wire is wound twice at the end of the spring portion 32 (referred to as a coil portion 33), and extends in the direction of the hook portion 31 substantially in parallel with the spring portion 32 (this portion is referred to as a base portion 34). The wire bends in a U-shape at the end of the base 34 (this portion is referred to as a U-shaped portion 35A), turns laterally beyond the position of the hook portion 31, and turns around the lower portion of the spring portion 32 (this portion is referred to as a stopper portion 36A). The U-shaped portion 35B is formed again. Finally, the wire extends from the second U-shaped portion 35B parallel to the base 34 (part 37) and is wrapped around the middle of the base 34 at the other end.

A buoy rope is attached to the coil part 33 of the connection fitting 30.
The lower end of 41 is tied.

On the other hand, a pair of two positioning pieces 20 are fixed to the lane rope 10 at a position where the lane buoy 40 is to be moored at a slight interval. The interval between the two positioning pieces 20 is determined by the two U-shaped portions 35A and 35A of the connecting bracket 30.
It is preferable that the width is slightly wider than the interval of B.

The positioning piece 20 is, for example, a short cylindrical metal pipe as shown in FIGS.
It has an inner diameter slightly larger than the diameter of the rope 10. The lane rope 10 is passed through the hole of the positioning piece 20 from one end thereof, and is fixed to the rope 10 by caulking the piece 20.

As shown in FIGS. 7 and 8, if a connecting piece 21 having a cross section close to a U-shape and having one open side is used, the piece 21 can be easily attached and fixed to the rope 10. That is, the rope 10 may be inserted into the piece 21 from the opened mouth of the connecting piece 21 and the piece 21 may be swaged.

Referring again to FIGS. 3 and 4, when the connecting fitting 30 is attached to the lane rope 10, the spring 32
Is pushed in the direction of the base 34, as indicated by the dashed line,
Insert the lane rope 10 into 35A and 35B. When the pressing of the spring portion 32 is stopped, the spring portion 32 returns to the original position by the elastic force, hits the stopper portion 36, and is kept at that position. In this state, the lane rope 10 is held by the U-shaped portions 35A and 35B and the hook 31 and does not fall out of these portions. Of course, two positioning pieces
In the position between 20, the connecting bracket 30 is connected to the lane rope 10
Attached to

The size of the space surrounded by the U-shaped portions 35A and 35B and the hook portion 31 is slightly larger than the diameter of the lane rope 10, and the U-shaped portions 35A and 35B, the hook portion 31 and the lane rope 10 There is a slight clearance between. Therefore, the connection fitting 30 is rotatable (turnable) around the lane rope 10.

The outer diameter of the positioning piece 20 is U-shaped portion 35A,
It is larger than the space surrounded by 35B and the hook 31. Therefore, the connection fitting 30 is regulated so as to be always between the two positioning pieces 20, and does not deviate from this position.

Such a pair of two positioning pieces 20
Are fixed to the lane rope 10 with a length to provide the lane buoy 40.

The setting of the lane is performed as follows.

At the factory, the lane rope 10 is tensioned and the lane rope 10
Mark 40 where to attach. At each of the marked positions of the lane rope 10, two pairs of positioning pieces 20 are fixed with a slight distance from each other.
The lane rope 10 to which the positioning piece 20 is attached is wound around a reel (or a drum) and transported to a lane setting site.

Lane and rope on winch installed on land
With one end of 10 fixed, the reel around which lane rope 10 is wound and lane buoy 40 are placed on the boat, and the boat is advanced along the path where lane rope 10 is to be stretched. The worker on the boat unwinds the lane rope 10 from the reel, and attaches the connection fitting 30 to the lane rope 10 between the two pieces 20 at the place where the pair of positioning pieces 20 are fixed. A lane buoy 40 is connected to the connection fitting 30 by a buoy rope 41. Place the lane buoy 40 attached to the lane rope 10 on the water. This operation is performed for each location where the positioning piece 20 is attached while pulling out the lane rope 10 from the reel.

The lane necessary for one lane rope 10
When the buoy 40 is installed, both ends of the lane rope 10 are fixed with a fixed object on land or an anchor anchored in water while tension is applied to the lane, and the lane rope 10 is fixed at a predetermined depth in the water. Stretch the rope 10. Figure 1 shows the Lane Buoy 40
As shown in (1), they are arranged in a straight line and float on the water surface to form lane 1.

The positioning piece 20 is fixed to the lane rope 10 in advance, and it is only necessary to attach the connecting fitting 30 to the lane rope 10 at the position of the positioning piece 20, so that the lane setting operation is easy.

Even if the lane rope 10 is twisted when the lane rope 10 is unwound from the reel, the connecting bracket
The buoy rope 41 does not become entangled with the lane rope 10 because the 30 is rotatable with respect to the lane rope 10.

A course for practice or competition (race) such as canoeing and rowing is generally formed by stretching a plurality of lane ropes in parallel at appropriate intervals.
Both ends of the plurality of lane ropes can be independently fixed by fixed objects on land or anchors anchored in water, but horizontal ropes can also be used as shown in FIG.

In FIG. 9, one end of a horizontal stretching rope 51 is fixed to a land (eg, a river shore) 50 by a fixing device 52. The anchor 52 is a heavy concrete block or a driving anchor. Winches are provided as needed. The winch is effective in applying tension to the rope 51.

The horizontal rope 51 is stretched diagonally from the land 50 toward the water, and the other end is fixed by an anchor 53 anchored in the water. Similar to the lane rope 10, the horizontal tension rope 51 is tensioned at a depth of about 1.5 m underwater with tension applied thereto. A float 54 is connected near the other end of the horizontal rope 51 by a rope, and the float 54 is floating on the water. From the place where the float 54 is connected, a support rope 55 branches off from the horizontal rope 51 at an appropriate angle and faces the land 50, the end of which is fixed on the land 50 by a fixing device 56. This support rope
55 is also tensioned in water and tensioned. The support rope 55 is not necessarily required.

The horizontal rope 51 may be stretched substantially perpendicularly to the boundary between the land 50 and the water. When making a course on a river, etc., if the opposite shore (the shore opposite to the land 50) is near, fix the other end of the horizontal rope 51 with an anchor 53 instead of fixing it with the anchor 53. You can also. In this case, the support rope 55 will not be needed.

An engaging metal fitting is attached to the horizontal rope 51 in advance at each location where the lane rope 10 is to be stretched. The engaging fitting has a hole or an opening through which the lane rope 10 passes. Preferably, a pulley for improving the lane rope 10 is provided to face the hole or opening. More preferably, the lane rope 10 is freely detachable from the side in the hole or opening of the engagement fitting.

The rope of the main float 57 is tied to the horizontal rope 51 at the place where the engagement fitting is attached. The main float 57 is floating on the water.

One end of the plurality of lane ropes 10 is 50 on land.
Is fixed by a fixing device 58, passes through a hole or an opening of an engagement fitting provided on the horizontal tensioning rope 51, is turned here, and is stretched in parallel. The other end of the lane rope 10 is anchored underwater by an anchor or fixed on land after being locked by a similarly stretched horizontal rope.

The fixing devices 56 and 58, like the fixing device 52, are composed of heavy concrete blocks, driving anchors (pile), etc., and are preferably provided with winches.

The course structure shown in FIG. 9 is made as follows.

An engaging metal fitting is preferably attached to the horizontal rope 51 in advance. A main float rope may be connected to the horizontal rope 51. The pair of two positioning pieces described above may be attached to the horizontal rope 51 at each position where the main float is connected. In this case, the main float can be attached by using the above-mentioned connection fitting.

In any case, one end of the horizontal rope 51 is fixed to the land 50, and the horizontal rope 51 and the main float 57 are fixed.
Are placed on the boat, the boat is moved along the path where the horizontal rope 57 is to be stretched, and the horizontal rope 57 is stretched while attaching the main float 57 to each of the engagement fittings.
The other end of the horizontal rope 57 is fixed by the anchor 53 or on the opposite bank.

The supporting rope 55 is stretched as required.

One end of the lane rope 10 is fixed to the land 50 by a fixing device 58, and the lane rope 10 and the lane rope 10 are fixed.
The buoy 40 is placed on the boat, and the boat advances toward the horizontal rope 51. By pulling the main float 57 or its rope upward, the horizontal rope 51 is pulled upward, and the lane rope 10 is passed through the fitting. Thereafter, the boat is advanced along the path where the lane rope 10 is to be stretched, and the buoy rope 41 of the lane buoy 40 is attached to the positioning piece 20 at each location of the positioning piece 20 as described above.

The other end of the lane rope 10 is fixed by an anchor, or is fixed to the land by being hooked to a horizontal rope 51 already stretched.

The above operation is repeated for a plurality of lane ropes 10.

Finally, use a winch or the like to stretch the rope
Tension is applied to 51, support rope 55 and lane rope 10 to make them tight.

A mark may be made at a place where the engaging metal fitting of the horizontal rope 51 is to be attached, and the attaching metal fitting and the rope of the main float 57 may be attached while the horizontal rope 51 is stretched.

This lane setting method is particularly effective when a lane is set in a place where land can be used, for example, a river. In a river, there is a flow of water, so it may be difficult to take a firm anchor. According to this method, at least one end of the rope is fixed on land, so that the rope can be easily fixed.
