Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a continuous water marking system for forming a long water course used for canoe competitions and the like.

[Conventional technology and its issues]

Along with the spread of outdoor sports, water sports such as canoeing, kayaking, and boating are becoming more popular. For example, canoe competitions are usually 9m wide.
Create about 10 lanes with a length of 500 to 1000 m,
Ranking will be determined by the navigation time within these lanes. What is important in conducting such water sports is to accurately form the course (lane), and the lanes are usually spaced at regular intervals (for example, 25 m).
It is divided into sections by placing floating signs (floats) on the water.

Traditionally, this type of water beacon was constructed by setting anchors at regular intervals on the bottom of a lake, river, bay, etc., securing a rope to each anchor, and floating a float connected to the top end of the rope on the water surface. was. However, with this configuration, an anchor is installed on the bottom of the water for each float, which requires a great deal of time and effort to set up and remove the course, and the topography of the bottom of the water can easily shift the anchor position, making it difficult to keep track of the lane. It is difficult to set the width accurately and constant. Furthermore, this configuration cannot respond to changes in water depth (water surface level), so the float's position may fluctuate dramatically, such as the float being submerged or rising excessively, or being blown away by wind or water currents.
There was a problem in that it easily interfered with competition management.

The present invention was devised to solve these shortcomings, and its purpose is to create a system in which the lane width is constant at any position regardless of changes in water depth, and all floats rise in an orderly manner. It is an object of the present invention to provide a continuous water marking system of this kind that can form a course and is also extremely easy to install and remove.

[Means to solve the problem]

In order to achieve the above object, the present invention includes at least two sets of parent floats having parent float sinkers suspended by ropes, and a required number of lane float sinkers arranged between the parent floats and each having a lane float sinker suspended by a rope. It is equipped with a lane float and an immersed rope with low elongation and almost zero weight underwater, the immersed rope has both ends guided to the land and is submerged by an underwater anchor at a portion outside the parent float to give tension, The structure is such that a parent float dipstick and a lane float dipstick are tied to this immersed rope.

In addition, in this invention, each float is defined as follows.

``Lane floats'' are landmarks for water athletes, markings on the water that separate each lane to clarify lane width and determine lane length. The "parent float" is a float for setting the underwater depth of the immersed rope, which is a means for arranging lane floats at predetermined intervals.

As the immersed rope, it is preferable to use a synthetic fiber rope that has low elongation and almost zero weight underwater, as well as relatively high tensile strength and elastic modulus.

Further, a spring-type locking fitting is preferably used as a means for connecting the parent float dipstick or lane float dipstick to the immersed rope.

Furthermore, it is also suitable to connect a pendant float to the underwater anchor via a rope. In the present invention, a "pendant float" is a water sign indicating the presence and position of an underwater object, particularly an underwater anchor.

This invention is applicable to canoes, kayaks, boats,
It can be used not only for competitions such as sailing, but also as a means for forming various divisions for water skiing, long distance swimming, etc.

[Action]

The immersed rope is forcibly submerged in water by underwater anchors at both sides in the longitudinal direction of the lane, thereby providing the desired tension. Between the underwater anchors, the immersed rope is set to a predetermined underwater depth by the balancing action of the parent float having a large buoyancy and the paired parent float sinker. Since the weight of the immersed rope in water is almost zero, it does not sag abnormally due to its own weight in the water, and a stable horizontal resting state is formed.

In this state, lane float dips are tied to the immersed rope at regular intervals, and lane floats are tied to the lane float dips via ropes, so each lane float is maintained at a moderate and equal amount. It sag and maintains a constant width at any position, and this characteristic does not change even if the water surface level changes.

Each lane float is supported by an immersed rope stretched underwater by an underwater anchor and a parent float sink, so there is no need for troublesome construction work such as installing underwater anchors, and each lane float assembly is The buoyancy of the immersed rope and the rope length are sufficient, and no complicated adjustments are required.Furthermore, when using spring-type locking fittings, it is possible to easily connect the immersed rope to the parent float sink, lane float sink, or underwater anchor. Since fulcrum formation and separation can be performed with a single touch, installation and removal work can be made easier and more efficient.

When a pendant float is attached to an underwater anchor via a rope, it is possible to immediately judge on the water surface whether the installation position of the underwater anchor and the tension of the immersed rope are appropriate, making it easier to adjust the tension. can be done.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 illustrate an embodiment of a continuous water beacon system according to the present invention.

In the drawing, the first lane A and the second lane B
It only shows. Reference numeral 1 designates an immersed rope, which is passed to both banks 12a and 12b to take the anchor.
It is wound up on winches 14a and 14b installed on foundations 13a and 13b provided on bases 13a and 12b. 2a,
2b is two underwater anchors on the left and right, 3a and 3b are multiple (two in the drawing) parent floats, 4a to 4x
is a number of lane floats.

The above-mentioned immersed rope 1 is used for arranging lane floats to be described later at specified intervals, and has a suitable characteristic of low elongation. The reason for this is that if elongation occurs over time due to creep or structural elongation, the tension will fluctuate, and the tension must be adjusted by operating the winches 14a, 14b each time.

Furthermore, it is appropriate that the immersed rope 1 has almost zero weight underwater. The reason for this is that metal ropes such as wire ropes have a small elongation but a large weight underwater, which causes abnormal sagging (sag), and the length of the rope that connects the lane floats each time depends on the position of the sagging catenary. This is because it would be necessary to change the height or use various types of lane floats with different buoyancy. In other words, this worsens work efficiency and increases costs.Also, as lane floats of different sizes and shapes coexist, the appearance of the course deteriorates, and when sailing near the edge of the lane, the oar This is because it may cause collisions, etc., which poses a problem in terms of competition management.

Further, it is desirable that the immersed rope 1 has relatively high tensile strength and elastic modulus from the viewpoint of ease of tension control and reduction of necessary diameter to suppress blowing by water flow. Taking these points into consideration, the immersed rope 1 is most preferably a synthetic fiber rope belonging to aromatic polyamide, ultra-high molecular weight polyethylene, or aromatic polyester.

The underwater anchors 2a and 2b are for forcibly submerging the immersed rope 1 into the water to generate a desired tension, and are connected to the parent float 3, respectively.
At a position closer to the shore than a and 3b, the fulcrum M ₁
It is connected to immersed rope 1 by.

The parent floats 3a and 3b are the underwater anchors 2
The parent float sinkers 5a, 2b are located inside the parent floats 5a and 2b, respectively, via the parent float ropes 30 at the bottom.
An assembly is constructed by suspending 5b. This assembly sets the underwater depth of the immersed rope 1, and the size and shape of the parent floats 3a and 3b are selected so that they have a considerably large buoyancy commensurate with the calculated tension of the immersed rope. Float sinker 5a, 5
B is also made to have a considerably heavy underwater weight for the same reason. The parent floats 5a and 5b are fulcrums.
The immersed rope 1 is connected to the immersed rope 1 by M ₂ , and the immersed rope 1 is thus stretched at a constant water depth (for example, 2 m) between the inner sides of the underwater anchors 2a and 2b, as shown in FIG.

The lane floats 4a to 4x are arranged at regular intervals (for example, 25 m) between the parent floats 3a and 3b to determine the lane length, and also to partition each lane A and B to determine the lane width. It is something. Each of the lane floats 4a to 4x has the same buoyancy, and the lane float rope 40 has a length equal to the water depth of the immersed rope 1.
One assembly is constructed by connecting the lane float sinkers 6a to 6x via the lane floats 6a to 6x. Each of the lane float sinkers 6a to 6x is for stabilizing the lane floats 4a to 4x, and therefore, it is preferable that their weight in water is about 1/2 of the buoyancy of the lane floats 4a to 4x. and,
Lane float sinker 6a to 6x for each assembly
is connected to the immersed rope 1 by a contact _M3 .

The underwater anchors 2a, 2b, the main float sinkers 5a, 5b and the lane floats 6a to 6x may be made of ropes to connect the immersed rope 1 to the fulcrums _M1 , _M2 , and _M3 .
The spring-type locking fitting 7 shown in Figs. 5a to 5c is preferably used. That is, the spring-type locking fitting 7 is made of a bent wire, and two arms 71 and 72 extend from a spring part 70 at the upper end. One arm 71 branches into two, descends, and then bends upward to connect the upper end of the rope to the attachment part 71.
The other arm 72 is pressed against the stopper 711 by the elasticity imparted by the spring portion 70. A hook portion 720 for holding the immersed rope is formed at the lower end of the arm 72. The opening side of the hook portion 720 is in contact with the mounting portion 710.
and the stopper 711 faces a bifurcated receiving portion 712 between them.

Therefore, as shown by the imaginary line, by moving the arm 72 away from the stopper 711 against the elasticity of the spring section 70, the hook section 720 protrudes outward. In this state, the immersed rope 1 is crossed over the hook part 720 and the pressure of the arm 72 is released, so that the immersed rope 1 crosses the hook part 720.
and the forked receiving portion 712 to form a fulcrum.

Note that in this embodiment, the underwater anchor 2
Each of a and 2b has a chain 20 in contact with the bottom of the water at its lower part, and a hanging rope 21 is connected to its upper part.
Pendant floats 9a, 9b are connected to the upper ends of the pendant ropes 8a, 8b.

The pendant ropes 8a, 8b and the pendant floats 9a, 9b have buoyancy that applies a predetermined tension to the immersed rope 1 when they float above the water surface, and the lengths of the pendant ropes 8a, 8b are set accordingly. I'll keep it. As a result, submergence of the pendant floats 9a and 9b indicates insufficient tension in the immersed rope 1, and conversely, excessive floating indicates an excessive tension state in the immersed rope 1. It is possible to correct the tension of the rope 1 to an appropriate level. Of course, the winches 14a and 14b
If side tension detection can be performed, the pendant floats 9a, 9b and pendant ropes 8a, 8b
can be omitted.

The parent floats 3a, 3b have bracket parts 31, 31 on both sides of the lower part as shown in Fig. 4, to which the upper end of the parent float rope 30 is connected, and the lower end has a spring type locking fitting as shown in Fig. 4a. It is inserted through and connected to the spring part 70 of 7, and the parent float sinker 5
a and 5b are removably connected to the mounting portion 710 of the spring-type locking fitting 7 by ring chucks 10a and 10b.

The lane floats 4a to 4x each have an upper end connected to the lower part of the lane float rope 40 as shown in FIG. The lane float dippers 6a to 6x are inserted and connected to the mounting portion 710 of the spring-type locking fitting 7 using a ring chuck or a dip rope 41.
is connected to.

The immersed rope 1 has fulcrums M 1 , 1 and ₂ with respect to the underwater anchors 2a and 2b, the parent float sinkers 5a and 5b, and the lane float sinkers 6a to 6x.
It is appropriate to form the indicating portion 18 using paint, tape, etc. at the portions corresponding to M ₂ and M ₃ . It goes without saying that synthetic fiber ropes are also suitable for each rope such as the parent float rope 30, the lane float rope 40, and the pendant ropes 9a, 9b.

Note that what is shown is an example of the present invention, and if the lane length is large, several parent float assemblies may be arranged not only on both sides but also in the middle area. Further, the anchor for the immersed rope 1 does not necessarily have to be land, but may be an anchored ship.

[Effect of the embodiment]

To obtain a competition course using the continuous water marking system of the present invention, prepare underwater anchor assemblies, parent float assemblies, lane float assemblies, and immersed ropes 1 for the required number of lanes. It is installed as shown in the figure, and the installation method and procedure are arbitrary.

That is, when assembling on land, the underwater anchors 2a, 2b and the parent float sinks 5a, 5 are placed in advance at predetermined positions on the immersed rope 1.
b. The lane floats 6a to 6x are connected using spring-type locking fittings 7. This can be done by simply gripping the arms 71 and 72, protruding the hook part 720 outward, placing the instruction part 18 of the immersed rope 1 on the hook part 720 so that it is located on the hook part 720, and releasing the gripping force. It is extremely simple. After this work, the immersed rope 1 is guided from one shore to the other shore, and the winches 14a, 14
A desired tension may be applied to the immersed rope 1 using b.

Another method is a floating assembly method. This may be done, for example, by the following procedure. That is, first, the immersed rope 1 is guided to the winches 14a, 14b on both banks 12a, 12b, and the immersed rope 1 is tensioned appropriately.
In this state, set the parent float assembly and lane assembly to immersed rope 1.

This can be done, for example, by first joining the left and right parent float assemblies and then setting the lane float assemblies in the desired order.
As shown in FIG. 6, these sets are carried out by sailing the work boat 15 loaded with the above-mentioned assemblies along the immersed rope 1, and using the indicator 18 as a guide, use the hook 16 to hold the immersed rope 1 on the water surface. It is easy because all you have to do is pull it up, operate the spring-type locking fitting 7 attached to the assembly as described above, attach the indicator part 18 of the immersed rope 1, and then repeat the process of dropping the assembly onto the water surface. be. At this time, even if the parent float assembly and the immersed rope 1 are connected, the immersed rope 1 is located horizontally at a shallow water depth, so the operation of connecting the lane float sinkers 6a to 6x is easy.

When the above work is completed, the area between the parent float assemblies on both sides of the immersed rope 1 is maintained at a constant water depth by the upward and downward pulling of the parent floats 3a, 3b and the parent float sinkers 5a, 5b, but the area outside the parent float assemblies, i.e., closer to the shore, remains unstable.

Therefore, next, underwater anchors 2a and 2b are set on the immersed rope 1. This setting can also be performed by the above-mentioned operation, whereby the immersed rope 1 receives the large underwater weight of the underwater anchors 2a, 2a, is forcibly pulled downward, and connects to the winches 14a, 14b side with the fulcrum _M1 as the boundary. Parent Sediment 3a,
Tension is generated on each side of 3b. This tension state can be immediately known by visually observing the pendant floats 8a, 8b, and the winches 14a, 14
An appropriate tension can be set by driving b.

This completes the installation of one continuous water sign, and the required number of lanes will be formed by performing the above operations in sequence.

The course obtained as described above has the following characteristics.

Since the water depth position of the immersed rope 1 is accurately determined by the parent floats 3a and 3b on both sides and the parent float dips 5a and 5b, the lane floats 4a to 4 attached to the immersed rope 1 are
4x alignment is good.

Since the immersed rope 1 has low elongation and almost zero weight underwater, it is easy to maintain a horizontal stationary state in the water, and each lane float 4a to 4x has a uniform floating state, and the lane float sinks 6a to 6x The flying height is always controlled to a suitable level, and it looks very good.

Immersed rope 1 is underwater anchor 2a, 2
Since a good tension is applied by b and the tension is stably maintained, it is possible to suppress the blowing of the lane floats 4a to 4x and the parent floats 2a and 2b, and also to prevent fluctuations in water depth in the depth direction. Since this can be automatically followed, there will be no change in the level of floating of the float.

When a rope with relatively high tensile strength and elastic modulus is used as the immersed rope, the elongation of the rope is further suppressed and the diameter of the rope can be made smaller, which reduces the disturbance of the course due to water flow.

[Effect of idea]

According to the present invention explained above, each float can always be kept stationary on the water surface with a constant floating amount regardless of the water depth, and can be maintained in regular positions lined up in an orderly manner, so the lane width suitable for various water sports can be adjusted. It is possible to form an accurate course, and since there is no need to install an anchor on the bottom of the water, the course can be formed and removed very easily, providing excellent effects.
