Description

Technical Field

[0001] The present invention relates to a mounting structure for mounting a lane rope buoy installed in a swimming competition pool, etc., on a rope, and a buoy group for a lane rope. In addition, the present invention relates to a buoy that can be mounted on a rope for dividing a swimming lane on the water surface or water in a swimming pool (hereinafter collectively referred to as "water surface"). Background Art

[0002] Various lane rope buoys are known in the past. For example, the lane rope buoy disclosed in Patent Document 1 includes a rope through hole in the center for passing a rope and a plurality of wing plates around the rope through hole. A plurality of lane rope buoys are arranged along the rope in the swimming pool to divide each lane. The lane rope buoy floats on the water surface and shakes by receiving waves raised by swimmers in each lane, thereby weakening and eliminating the waves, that is, making swimming easier by "breaking the waves".

[0003] However, there is a problem that a swimmer may turn around and change the swimming direction on the outer wall side of the swimming lane, but after turning around, the swimmer may encounter waves generated when swimming towards him / her, making swimming difficult.

[0004] In addition, in a swimming pool for swimming competitions, many lane ropes are set up to divide the swimming lanes into lanes for each swimmer, and many buoys are installed on each rope (see Patent Document 2). In recent years, in order to reduce and reduce the waves caused by swimmers on the water surface (hereinafter referred to as "wave reduction"), it is required to improve the level of wave reduction function of these buoys.

[0005] Especially in the swimming competition that many players participate in, the swimmers of the competition hope to be able to swim in a stable condition without waves, so as to avoid the adverse effects of the waves on the water surface surging from other (next) swimming lanes.

[0006] In the case of Patent Document 2, the buoy has a shaft tube for inserting a rope in the middle position thereof, and a plurality of wing plates extending outward are formed on the shaft tube, and the wing plates divide the entire space in the buoy into a plurality of small spaces. A circumferential outer wall is formed at the outer edge of the wing plate to connect adjacent wing plates. The outer wall has an annular portion that blocks waves coming from the surface of the swimming pool outside the buoy, and the annular portion forms a window hole that can introduce waves coming from the surface of the swimming pool.

[0007] In the case of the above-mentioned buoy, the wave energy transmitted to the water entering the window hole is consumed by the shaking of the buoy, etc., so the waves caused by the swimmer gradually disappear. The present inventors conducted a detailed study on the shaking of the buoy, and found that there is a possibility of further improving the disappearance of waves by making further improvements. After various trials and errors, the present invention was completed. Prior art literature Patent Literature

[0008] Patent Document 1: Japanese Utility Model Publication No. 61-15920 Patent Document 2: Japanese Utility Model Registration No. 3039436 Summary of the invention Technical Problems to be Solved by the Invention

[0009] In view of the above problems, the present invention provides a swimming lane rope buoy installation structure and a swimming lane rope buoy group that make it easy for swimmers to swim and swim after turning back. In addition, the present invention aims to provide an excellent buoy that can consume the energy of waves propagating on the water surface faster than the prior art by variously designing the structure inside the buoy. Technical solutions for solving technical problems

[0010] In order to solve the above-mentioned problems, the installation structure for installing multiple lane rope buoys on a rope according to Item 1 of the present application is characterized in that: the lane rope buoys are installed on the rope via a cylindrical portion and are connected to the outer wall of the swimming pool to divide each swimming lane, the lane rope buoys are formed of a synthetic resin material, and the gap between at least a portion of the lane rope buoys on the rope side connected to the outer wall of the swimming pool is wider than the gap between at least a portion of the lane rope buoys arranged near the middle of the swimming pool.

[0011] According to the above-mentioned features, the wide gaps between the lane rope buoys on the rope side connected to the outer wall of the swimming pool can allow more waves to overflow into the adjacent lanes, thereby reducing the shaking and turbulence of the water surface, making it easier to swim after turning back. On the other hand, near the center of the swimming pool, since the gaps between the lane rope buoys are narrow, it is difficult for waves to overflow into the adjacent lanes, and there is a moderate sense of resistance, so that the swimmer can feel the weight of the water and it is easier to swim.

[0012] Furthermore, regarding Item 2 of the present invention, the lane rope buoy group having a plurality of lane rope buoys is characterized in that the lane rope buoys are installed on ropes via a tubular portion and connected to the outer wall of the swimming pool to divide each lane, are formed of a synthetic resin material, and have spacers installed between the lane rope buoys.

[0013] According to the above features, on the rope side connected to the outer wall of the swimming pool, since the gaps between the lane rope buoys are widened by spacers, more waves can overflow to adjacent lanes, reducing the shaking or turbulence of the water surface, making it easier to swim after turning back.

[0014] Furthermore, regarding Item 3 of the invention of the present application, the lane rope buoy group having a plurality of lane rope buoys is characterized in that: there are spacers installed between the above-mentioned lane rope buoys so that the gap between at least a portion of the above-mentioned lane rope buoys on the rope side connected to the outer wall of the above-mentioned swimming pool is wider than the gap between at least a portion of the above-mentioned lane rope buoys arranged near the center of the above-mentioned swimming pool.

[0015] According to the above-mentioned features, on the rope side connected to the outer wall of the swimming pool, since the gap between the lane rope buoys is widened by the spacer, more waves can overflow to the adjacent lanes, the shaking and turbulence of the water surface are reduced, and it becomes easier to swim after turning back. On the other hand, near the center of the swimming pool, since the gap between the lane rope buoys is narrow, it is difficult for waves to overflow to the adjacent lanes, there is a moderate resistance feeling, and the swimmer can feel the weight of the water, and it is easy to swim.

[0016] Furthermore, regarding the installation structure of installing multiple lane rope buoys on a rope of Item 4 of the present invention, it is characterized in that: the above-mentioned lane rope buoys are installed on the above-mentioned rope via a cylindrical portion and are connected to the outer wall of the swimming pool to divide each swimming lane, and are formed of a synthetic resin material, and the width of at least a portion of the above-mentioned lane rope buoys arranged near the center of the above-mentioned swimming pool is wider than the width of at least a portion of the above-mentioned lane rope buoys on the rope side connected to the outer wall of the above-mentioned swimming pool.

[0017] According to the above-mentioned features, near the center of the swimming pool, since the width of the lane rope buoys is wide, the gaps between the lane rope buoys are small, so waves are not easy to overflow to the adjacent swimming lanes, and there is a moderate sense of resistance, and the swimmer can feel the weight of the water and swim easily by paddling. On the other hand, on the rope side connected to the outer wall of the swimming pool, since the width of the lane rope buoys is narrow, the gaps between the lane rope buoys are large, so more waves can overflow to the adjacent swimming lanes, the shaking and turbulence of the water surface are reduced, and it becomes easier to swim after turning back.

[0018] Furthermore, regarding the installation structure of installing multiple lane rope buoys on a rope of Item 5 of the present invention, it is characterized in that: the above-mentioned lane rope buoys are installed on the above-mentioned rope via a cylindrical portion and are connected to the outer wall of the swimming pool to divide each swimming lane, and are formed of a synthetic resin material, and the transmittance of at least a portion of the above-mentioned lane rope buoys on the rope side connected to the outer wall of the above-mentioned swimming pool is 2 to 30%, which is higher than the transmittance of at least a portion of the above-mentioned lane rope buoys arranged near the center of the above-mentioned swimming pool.

[0019] According to the above characteristics, near the center of the swimming pool with low permeability, waves are not easy to overflow to the adjacent swimming lanes, and there is a moderate resistance feeling. The swimmer can feel the weight of the water and swim easily by paddling. On the other hand, on the rope side connected to the outside of the swimming pool with high permeability, waves are easy to overflow to the adjacent swimming lanes, and it becomes easy to swim after turning back. In particular, by making the permeability 2 to 30%, the gap between the buoys for the swimming lane ropes can be widened, so that more waves overflow to the adjacent swimming lanes, reducing the shaking or turbulence of the water surface, and making it easy to swim after turning back.

[0020] Furthermore, regarding the installation structure of item 6 of the present invention, in which a plurality of lane rope buoys are installed on a rope, it is characterized in that: the lane rope buoys are installed on the rope via a cylindrical portion and are connected to the outer wall of the swimming pool to divide each swimming lane, and are formed of a synthetic resin material, and the transmittance of at least a portion of the lane rope buoy on the rope side connected to the outer wall of the swimming pool is 3 to 7%.

[0021] According to the above characteristics, on the side of the rope connected to the outside of the swimming pool with high transmittance, waves easily overflow to the adjacent lane, making it easier to swim after turning back. In particular, by setting the transmittance to 3 to 7%, the gap between the buoys for the lane ropes can be widened, allowing more waves to overflow to the adjacent lane, reducing the shaking and turbulence of the water surface, making it easier to swim after turning back.

[0022] Furthermore, in order to solve the above problems, the present invention has the following means. That is, according to a method for embodying the present invention, there is a buoy installed on a rope for dividing the water surface of a swimming pool into swimming lanes, characterized in that it comprises: a central mounting portion, which is arranged in a manner that the rope can be inserted at a central position in the buoy; an outer wall portion, which blocks waves propagating from the water surface of the swimming pool on the outer wall surface and forms an opening that can introduce waves propagating from the water surface of the swimming pool into the space in the buoy; a plurality of wing plates, which connect the outer wall portion to the central mounting portion and are extended in the direction in which the rope extends to divide the space in the buoy into a plurality of spaces; and a connecting portion, which connects the plurality of wing plates to each other and has a water outlet that can discharge the waves introduced into the space in the buoy through the opening; when the volume of a single space separated by at least a pair of adjacent wing plates, the outer wall portion adjacent to the wing plates, and the connecting portion adjacent to the wing plates is set to A1, and when the area of ​​the water outlet associated with the single space is set to B1, the ratio of A1 to B1 is set to an allowable value above a lower limit and below an upper limit.

[0028] Hereinafter, embodiments of the present invention will be described using the drawings.

[0029] <Implementation method 1> first, Figure 1 and Figure 2 A swimming lane rope buoy 100 according to Embodiment 1 of the present invention is shown. Figure 1 This is an overall stereogram of a swimming lane rope buoy 100. Figure 2 (a) is a front view of the swimming lane rope buoy 100, Figure 2 (b) is a side view of the lane rope buoy 100.

[0030] The lane rope buoy 100 is a competition buoy and has the same shape. In addition, the lane rope buoy 100 includes a long cylindrical portion 110 located at the center of the lane rope buoy 100 and through which the rope R can be inserted, a plurality of wing plates 120 protruding from the side 111 of the cylindrical portion 110 in parallel with the rope R, and a wall portion 130 connected to the side end 121 of the wing plate 120 and covering the wing plate 120. In addition, the outer periphery of the lane rope buoy 100 has a diameter of 110 to 150 mm (millimeter). In addition, the diameter of the lane rope buoy 100 is set to 110 to 150 mm (millimeter) because the lane rope buoy 100 of the present invention has a significant effect on the ease of swimming during the turn, especially when used in a speed competition, the effect is large, making the lane rope buoy 100 suitable for the competition rules (refer to "Pool Recognized Rules" Public Interest Incorporated Foundation Japan Swimming Federation 2018). In addition, the competition rules stipulate that the diameter of the lane rope buoy (lane rope buoy) is 50 mm or more and 150 mm or less, and the international swimming pool stipulates 150 mm. In contrast, the lane rope buoy 100 of the present invention has a diameter of 110 to 150 mm.

[0031] In addition, as described later, Figure 4 The gap X between the lane rope buoys 100 on the rope R side connected to the outer wall 910 of the swimming pool 900 shown needs to be set in such a way that waves can easily overflow to adjacent lanes and the lane rope buoys 100 themselves can withstand waves and rotate appropriately to ensure wave-breaking performance.

[0032] Here, if Figure 4 As shown, the height H2 of the gap X between the lane rope buoys 100 is equal to the diameter of the lane rope buoy 100. Moreover, most of the waves passing through the gap X will pass through the area other than the rope R, and the rope R will become an obstacle when the waves pass through. Therefore, the height H1 of the gap X other than the rope R (the height from the rope R or the spacer 800 to the wall portion 130 of the lane rope buoy 100) is closely related to the ease of wave overflow and the appropriate rotation of the lane rope buoy 100. Specifically, the lower the height H1 of the gap X, the easier it is for the wave to cross the gap X or overflow the lane rope buoy 100 to the adjacent lane. On the other hand, if the height H1 of the gap X is too low, the generated waves will exceed the lane rope buoy 100, and the waves flowing from the gap X side into the inside of the lane rope buoy 100 will become too small, and the appropriate rotation of the lane rope buoy 100 cannot be achieved. Therefore, it is necessary to ensure a certain degree of height to prevent the height H1 of the gap X from being too low. In addition, the appropriate rotation of the lane rope buoy 100 is not limited to the case where the lane rope buoy 100 rotates once, and also includes the case where the lane rope buoy 100 rotates several times from the horizontal state to consume the wave energy.

[0033] Here, in the swimming competition rules (refer to the "Swimming Competition Rules" of the Japan Swimming Federation), there is one rope R separating adjacent lanes, and the diameter of the rope R is specified to be greater than 50 mm and less than 150 mm. Therefore, assuming that the diameter of the rope R is the lower limit of 50 mm, in the present invention, the diameter of the lane rope buoy 100 is set to be greater than 110 mm. Accordingly, it can be ensured to a certain extent that the height H1 of the gap X is not too low, and the waves are easily overflowed into the adjacent lanes, and the lane rope buoy 100 itself also withstands the waves and rotates appropriately to ensure the wave-breaking performance. In addition, in the case where the diameter of the rope R is the lower limit of 50 mm, if the diameter of the lane rope buoy 100 is set to be greater than the lower limit of 50 mm and less than 110 mm specified in the competition rules, the height H1 of the gap X becomes too low.

[0034] The wall surface 130 between the adjacent wing plates 120 is formed at an inclination. Moreover, openings 140 are formed on both sides of the inclined portion to form a gap in the wall surface 130, and waves entering from the side enter the inside of the lane rope buoy 100 from the openings 140. Furthermore, a protruding plate 150 is formed on the inner surface of the wing plate 120 in a manner protruding from the surface and parallel to the rope R. Moreover, since the waves flowing in from the openings 140 hit the protruding plate 150, turbulence is more likely to be generated in the lane rope buoy 100.

[0035] In addition, if Figure 2 As shown in (b), one outer end 112 of the cylindrical portion 110 is slightly more recessed inward than the outer end 122 of the wing 120, that is, than the outer end 170 of the lane rope buoy 100. In addition, the other outer end 113 of the cylindrical portion 110 protrudes slightly more outward than the outer end 122 of the wing 120, that is, than the outer end 170 of the lane rope buoy 100. As described below, when a plurality of lane rope buoys 100 are mounted on the rope R for use, the other protruding outer end 113 of the adjacent lane rope buoy 100 is embedded in the one recessed outer end 112 of the adjacent lane rope buoy 100, so that the positions or postures of the adjacent lane rope buoys 100 are maintained without being offset.

[0036] In addition, if Figure 1 and Figure 2 As shown, the partition wall 160 is integrated in the central part of the lane rope buoy 100, and a water hole 161 is formed in the partition wall 160 to allow water to flow in from the front and back. In addition, the six wing plates 120 are arranged at equal intervals, that is, at intervals of 60 degrees, with the cylindrical portion 110 as the center, so that the opposing wing plates 120 are arranged in a straight line. In addition, the number or arrangement of the wing plates 120 is not limited to Figure 1 and Figure 2In addition, at the outer end portion 170 of the lane rope buoy 100, at least half (1 / 2), preferably 2 / 3, and more preferably 4 / 5 of the range from the center of the cylindrical portion 110 to the wall portion 130 is formed along a vertical plane relative to the cylindrical portion 110.

[0037] In addition, the entirety of the lane rope buoy 100 is formed by injection molding a foamed synthetic resin material in order to float on the water. As the synthetic resin material, polypropylene or polyethylene can be used. In addition, as the synthetic resin material, soft materials such as PE (Polyethylene) or EVA (Ethylene Vinyl Acetate) can be used. In addition, the entirety of the lane rope buoy 100 can also be blow-molded by a synthetic resin material. In addition, in order to prevent fading, the lane rope buoy 100 can also be formed by EVA resin colored with an inorganic pigment.

[0038] Second, use Figures 3 to 7 , the installation structure of installing a plurality of lane rope buoys 100 on the rope R will be described. Figure 3 (a) is a top view of a swimming pool 900 in which a plurality of lane rope buoys 100 are installed on a rope R. Figure 4 1 is a side view of a lane rope buoy 100 disposed on the outer wall 910 side of a swimming pool 900. Figure 5 1 is a side view of a lane rope buoy 100 disposed near the center 920 of a swimming pool 900. Figure 6 1 is a side view of a lane rope buoy 100 disposed on the outer wall 910 side of a swimming pool 900. Figure 7 It is a front view of the lane rope buoy 100 in a state of floating on the water surface W of the swimming pool.

[0039] like Figure 3 As shown, each lane (P1, P2, P2) is divided by a rope R connected and stretched to the outer wall 910 on both sides of the swimming pool 900. The rope R is inserted into the cylindrical portion 110 of each lane rope buoy 100, and a plurality of lane rope buoys 100 are connected along the rope R.

[0040] like Figure 4As shown, in the installation structure of the lane rope buoy 100 of the present invention, a spacer 800 is arranged between adjacent lane rope buoys 100 on the rope R side connected to the outer wall 910 of the swimming pool 900. The spacer 800 is formed of a synthetic resin material and has a substantially cylindrical shape. A through hole 810 is provided at the center for the rope R to pass through. The spacer 800 allows the rope R to pass through the through hole 810 and is installed on the rope R. Moreover, on the rope R side connected to the outer wall 910 of the swimming pool 900, the width L1 of the gap between adjacent lane rope buoys 100, that is, the gap between the outer ends 170 of adjacent lane rope buoys 100 is widened by the spacer 800. In addition, the gap between adjacent lane rope buoys 100 is the gap between the outer ends 170 of the adjacent lane rope buoys 100, and is a part of the area S2 between the outer ends 170 of the lane rope buoys 100.

[0041] In addition, by using the spacer 800 which is different from the lane rope buoy 100, if the width of the spacer 800 is appropriately changed, the width L1 of the gap between the lane rope buoys 100 can be easily changed. In addition, when the lane rope buoy 100 is installed and arranged, the outer end surface of the spacer 800 abuts against the end surface (113C side) of the adjacent lane rope buoy 100, and the spacer 800 is interposed between the lane rope buoys 100, so that the adjacent lane rope buoys 100 do not directly contact each other, thereby preventing the lane rope buoys 100 from contacting each other and making the lane rope buoys 100 difficult to rotate, or preventing the lane rope buoys 100 from contacting each other and wearing each other. In addition, the spacer 800 is preferably formed of a synthetic resin material having a higher hardness than the synthetic resin material constituting the lane rope buoy 100. Furthermore, the inner side of the spacer 800 is made harder and smoother than the inner side of the cylindrical portion 110 of the lane rope buoy 100, so that the lane rope buoy 100 is easy to rotate and the cylindrical portion 110 of the lane rope buoy 100 is not easily grinded. Furthermore, the spacer 800 can be formed of polyethylene, and even if it is made of the same raw material as the lane rope buoy 100, the surface hardness can be harder than that of the lane rope buoy 100. The lane rope buoy 100 can be a foamed product formed by foaming, or a non-foamed solid product formed by injection molding, which has a harder surface hardness than a blow-molded product formed by blow molding. In addition, the spacer 800 is not limited to Figure 4The form shown may be a form in which a gap between the lane rope buoys 100 is formed by installing an object, a clip or a washer on the rope, for example, in the cylindrical portion 110. In addition, the shrinkage rate of the lane rope buoy 100 varies depending on the color of the material used, so it is preferable to combine the spacer 800 with other items such as a washer to adjust the gap to match the transmittance per 1m. Specifically, the lane rope for a swimming pool changes color to make a distance of 5m or 10m clear, and lane rope buoys of multiple colors are installed on one lane rope. Since the shrinkage rate of the lane rope buoys of each color is different, the spacer 800 is installed between the lane rope buoys to adjust the distance. When the spacer 800 is installed between the lane rope buoys, the spacer 800 may be installed every one or more lane rope buoys, or the spacer 800 may be installed evenly or unevenly on one lane rope. Furthermore, the spacer 800 and the lane rope buoy 100 are separate bodies, but the present invention is not limited thereto, and a convex portion may be integrally formed at the end of the cylindrical portion 110 and the convex portion may be used instead of the spacer.

[0042] Secondly, if Figure 5 As shown, the spacer 800 is not installed between the adjacent lane rope buoys 100 near the center 920 of the swimming pool 900. Therefore, the width L2 of the gap between the adjacent lane rope buoys 100, that is, the gap between the outer ends 170 of the adjacent lane rope buoys 100 is narrowed. In addition, the gap L1 between the lane rope buoys 100 on the rope R side connected to the outer wall 910 of the swimming pool 900 is wider than the gap L2 between the lane rope buoys 100 arranged near the center 920 of the swimming pool 900 (L1>L2).

[0043] In addition, whether Figure 4 The rope R side connected to the outer wall 910 of the swimming pool 900 is also as shown. Figure 5 In the center 920 side of the swimming pool 900 shown, the lane rope has the same function of eliminating waves with the buoy 100. Specifically, as Figure 7 As shown, the rope R is set near the water surface W, and the lane rope buoy 100 attached to the rope R floats on the water surface W. In this state, the waves generated by the swimmers in the adjacent lanes travel toward the lane rope buoy 100 from the side. In this way, a part of the wave (see W1) shakes the water surface W up and down, and enters the interior of the lane rope buoy 100 from the opening 140 above the water surface W.

[0044] In addition, another part of the wave (see W2) enters the interior of the lane rope buoy 100 from the opening 140 sunk below the water surface W. The wave entering the interior of the lane rope buoy 100 hits the wing plate 120 or the protruding plate 150, and the lane rope buoy 100 is shaken up and down by the force, or the lane rope buoy 100 is shaken around the rope R. In this way, the kinetic energy of the wave is converted into the rotational energy of the lane rope buoy 100 and consumed, and as a result, the wave disappears.

[0045] However, the swimmer may turn around and change the swimming direction on the outer wall 910 side of the swimming pool 900, but the swimmer may hit the waves generated when swimming towards him after turning around, which makes swimming difficult. Moreover, regarding the large waves when the swimmer turns around, compared with using the lane rope to eliminate most of the waves, using the buoy 100 to make a part of the waves overflow to the adjacent lane can reduce the shaking or turbulence of the water surface W, making swimming easier after turning around.

[0046] In this regard, Figure 4 As shown, the width L1 of the gap X between the lane rope buoys 100 on the rope R side connected to the outer wall 910 of the swimming pool 900 is made wider than the width L2 of the gap between the lane rope buoys 100 arranged near the center 920 of the swimming pool 900. On the rope R side connected to the outer wall 910 of the swimming pool 900, since the gap X between the lane rope buoys 100 is set wider, waves are easy to overflow to the adjacent swimming lanes, and the lane rope buoys 100 themselves are easy to rotate, so the wave-breaking performance is also ensured. As a result, in the installation structure of the lane rope buoys 100 of the present invention, the shaking or turbulence of the water surface W is reduced, and it is not easy to be hit by the waves generated by itself after turning back, and it becomes easy to swim after turning back. On the other hand, near the center 920 of the swimming pool 900, since the gap between the lane rope buoys 100 is narrow, the waves are not easy to overflow to the adjacent swimming lanes, there is a moderate sense of resistance, and the swimmer can feel the weight of the water, and it is easy to swim by paddling.

[0047] In addition, the width of the lane rope buoy 100 on the rope R side connected to the outer wall 910 of the swimming pool 900 is the same as the width of the lane rope buoy 100 arranged near the center 920 of the swimming pool 900, but the rope R side connected to the outer wall 910 of the swimming pool 900 is wider than the width L1 of the gap X between the lane rope buoys 100, so the lane rope buoy 100 is easier to rotate and has a high wave-breaking performance. Figure 3As shown, in the swimming pool 900, at a distance L10 from the outer wall 910 along the length direction of the rope R within 15 m (meter), preferably within 7 to 15 m (meter), or preferably within the Vassallo mark, the width L1 of the gap X between the lane rope buoys 100 is made wider than the width L2 of the gap between the lane rope buoys 100 arranged near the center 920 of the swimming pool 900. In addition, in the lane rope buoys 100 occupying 80 to 99% of the distance L10 from the outer wall 910, the width L1 of the gap X between the lane rope buoys 100 is wider than the width L2 of the gap between the lane rope buoys 100 arranged near the center 920.

[0048] In addition, the lane rope buoy set of the present invention includes lane rope buoys 100 and spacers 800. The spacers 800 can widen the gaps between the lane rope buoys 100 on the rope R side connected to the outer wall 910 of the swimming pool 900. As a result, on the rope R side connected to the outer wall 910 of the swimming pool 900, waves easily overflow from the wide gaps between the lane rope buoys 100 to the adjacent swimming lanes, and since the lane rope buoys 100 themselves are easy to rotate, wave-breaking performance is also ensured. As a result, the shaking or turbulence of the water surface W is reduced, and it becomes easy to swim after turning back. On the other hand, near the center 920 of the swimming pool 900, since the gaps between the lane rope buoys 100 are narrow, waves are not easy to overflow to the adjacent swimming lanes, and there is a moderate sense of resistance, and the swimmer can feel the weight of the water and easily swim by paddling.

[0049] Furthermore, when arranging the lane rope buoys 100, the gaps between the adjacent lane rope buoys 100 are set at a portion of at least 8% from the center of the lane rope buoys 100 in the vertical direction, so that more waves can overflow into the adjacent lanes, the shaking or turbulence of the water surface is reduced, and it becomes easier for swimmers to swim after turning back. That is, if Figure 4 As shown, the portion where the central side gap of the lane rope buoy 100 is closed ( Figure 4 The height H3 of the lane rope buoy 100 (where the rope R or the spacer 800 is present) is less than 8% of the height H2 of the lane rope buoy 100. Furthermore, the gap X is set wider at a position further outward than a portion that occupies at least 8% in the vertical direction from the center of the lane rope buoy 100 (a portion of the height H3 that is 8% of the height H2) relative to the height H2 of the lane rope buoy 100. Furthermore, if the gap between the lane rope buoys 100 is set to a position of 8% or more, more preferably 10% in the vertical direction from the center, a moderate amount of waves is blocked by the lane rope buoy 100 to generate a sense of resistance (weight of water), and the effect of making it easy for the swimmer to swim back can be obtained by this moderate resistance.

[0050] In addition, if Figure 5 As shown in the figure, the spacer 800 is not installed near the center 920 of the swimming pool 900, and the width L2 of the gap between the lane rope buoys 100 is narrowed, but the present invention is not limited thereto. If the width L2 of the gap between the lane rope buoys 100 near the center 920 of the swimming pool 900 is narrower than the width L1 of the gap between the lane rope buoys 100 on the outer wall 910 side of the swimming pool 900, for example, the width L2 may be narrower than the width L1 of the gap between the lane rope buoys 100 near the center 920 of the swimming pool 900. Figure 4 The spacer 800 shown is installed between the lane rope buoys 100. In addition, as Figure 5 As shown, near the center 920 of the swimming pool 900, the width L2 of the gaps between the lane rope buoys 100 is uniform, as shown in FIG. Figure 4 As shown, the width L1 of the gaps between the lane rope buoys 100 becomes uniform near the outer wall 910 of the swimming pool 900, but the present invention is not limited thereto. The width of the gaps between the lane rope buoys 100 may gradually widen from the center 920 of the swimming pool 900 to the outer wall 910.

[0051] In addition, if Figure 4 As shown, near the outer wall 910 of the swimming pool 900, the lane rope buoys 100 are continuously arranged in such a manner that the width L1 of the gaps between the lane rope buoys 100 becomes uniform, but this is not limited to this. Near the outer wall 910 of the swimming pool 900, as long as the width L1 of the gaps between at least a part of the lane rope buoys 100 becomes wider, the lane rope buoys other than the lane rope buoys 100 arranged with the width L1 may be arbitrarily arranged and constructed. For example, the lane rope buoys other than the lane rope buoys 100 arranged with the width L1 may be arranged at intervals narrower than the width L1, or may be lane rope buoys of different types. The reason is that even in this case, if the width L1 of the gaps between at least a part of the lane rope buoys 100 becomes wider, the waves are likely to overflow to the adjacent lanes, and the lane rope buoys 100 themselves are likely to rotate, thereby ensuring wave-breaking performance, reducing the shaking or turbulence of the water surface W, and making it easier to swim after turning back. Similarly, as Figure 5 As shown, near the center 920 of the swimming pool 900, the lane rope buoys 100 are continuously arranged in such a manner that the width L2 of the gaps between the lane rope buoys 100 becomes uniform, but this is not limited to this. Near the center 920 of the swimming pool 900, as long as the width L2 of the gaps between at least a portion of the lane rope buoys 100 is narrowed, the lane rope buoys other than the lane rope buoys 100 arranged with the width L2 may be arbitrarily arranged and constructed.

[0052] In addition, if Figure 6As shown in FIG. 1 , on the rope R side connected to the outer wall 910 of the swimming pool 900, the gap between the lane rope buoys 100 is widened to facilitate the passage of waves, and the wave passing rate, i.e., the permeability of the gap, which quantitatively represents the ease of passage of waves, is set to 2 to 30%. Here, the so-called permeability is defined as the ease of passage of waves in adjacent lane rope buoys 100, such as Figure 6 As shown, it is the ratio of the area S2 of the gap X between the swimming lane rope buoys 100 to the area S1 occupied by the swimming lane rope buoys 100 in a side view.

[0053] Specifically, the area S1 occupied by the so-called swimming lane rope buoy 100 is as follows: Figure 6 As shown, in a side view, the area of ​​the quadrilateral portion surrounded by the center line D1 of the adjacent lane rope buoy 100 and the straight line D2 connecting the wall portions 130 on the outside of the lane rope buoy 100 ( Figure 6 In addition, the area S2 of the gap X between the so-called lane rope buoys 100 is as follows: Figure 6 As shown, in a side view, the area of ​​the entire gap X between the outer ends 170 of the adjacent lane rope buoys 100 is ( Figure 6 The area indicated by the diagonal lines in the middle). In addition, the transmittance (%) is obtained by dividing the area S2 by the area S1 and multiplying it by 100. That is, it is derived by the calculation formula: transmittance (%)=(S2÷S1)×100.

[0054] Furthermore, by setting the transmittance of the gap X between the lane rope buoys 100 to 2 to 30% on the rope R side connected to the outer wall 910 of the swimming pool 900, the gap between the lane rope buoys 100 can be widened, so that more waves can overflow to the adjacent lanes, the shaking or turbulence of the water surface can be reduced, and it becomes easier for the swimmer to swim after turning back. Furthermore, if the transmittance of the gap between the lane rope buoys 100 is set to 2 to 10%, preferably 3 to 7%, and more preferably 4 to 5%, a moderate amount of waves is blocked by the lane rope buoys 100 to generate a sense of resistance, and the moderate resistance (weight of water) can achieve the effect of making the swimmer turn back and swim easily.

[0055] In addition, the openings 140 of adjacent lane rope buoys 100 are roughly parallelogram-shaped and are arranged so as to span the gap X between the lane rope buoys 100. By making the overlap between the openings 140 of adjacent lane rope buoys 100 and the gap X at least 0% to 10%, and more preferably 1 to 2%, a moderate amount of waves entering from the openings 140 of the lane rope buoys 100 will overflow into the adjacent lane, reducing the shaking or turbulence of the water surface, and making it easier for the swimmer to swim after turning back. Specifically, the waves entering the openings 140 become turbulent and are damped, and are further damped when passing through the gap X. That is, if the larger openings 141 (see Figure 6 The area of ​​the roughly parallelogram opening) is set to Z0, and the portion where the opening 141 overlaps with the gap X ( Figure 6 The area of ​​the opening 141 (indicated by the oblique lines in the middle) is set to Z1. The best setting of the area Z1 is 0% to 10% of the area Z0, and more preferably 1 to 2%.

[0056] The top 10 swimmers in Japan, who are known as the best swimmers, or swimmers who can swim a few seconds slower than the Japanese record are likely to feel the resistance and weight of the water in the swimming pool through their skin, which can easily affect their swimming competition results.

[0057] On the other hand, Figure 5 As shown, near the center 920 of the swimming pool 900, the spacer 800 is not installed to narrow the width L2 of the gap between the lane rope buoys 100. Therefore, near the center 920 of the swimming pool 900, the transmittance of the gap between the lane rope buoys 100 is reduced only by the narrower width L2 of the gap. That is, Figure 6 The transmittance of the gap between the lane rope buoys 100 on the rope R side connected to the outer wall 910 of the swimming pool 900 is higher than Figure 5 The transmittance of the gap between the lane rope buoys 100 near the center 920 of the swimming pool 900 shown in FIG. As a result, near the center 920 of the swimming pool 900 where the transmittance is low, the waves are not easy to overflow to the adjacent swimming lanes, and there is a moderate resistance feeling, and the swimmer can feel the weight of the water and swim easily. On the other hand, on the rope R side connected to the outer wall 910 of the swimming pool 900 where the transmittance is high, the waves are easy to overflow to the adjacent swimming lanes, and it becomes easy for the swimmer to swim after turning back. In addition, it is best that the difference (T1-T2) between the transmittance (T1) of the gap between the lane rope buoys 100 on the rope R side connected to the outer wall 910 of the swimming pool 900 and the transmittance (T2) of the gap between the lane rope buoys 100 near the center 920 of the swimming pool 900 is 0<(T1-T2)<10, and more preferably 0<(T1-T2)<5.

[0058] <Implementation method 2> Secondly, refer to Figure 8 , the installation structure of the swimming lane rope buoy using the swimming lane rope buoy 100A of the second embodiment of the present invention is described. Figure 8 (a) is a side view showing a state where a plurality of lane rope buoys 100 are installed on the rope R side connected to the outer wall 910 of the swimming pool 900. Figure 8 (b) is a side view showing a state where a plurality of lane rope buoys 100A are attached to a rope R near the center 920 of the swimming pool 900. The lane rope buoys 100A of the second embodiment of the present invention are different in structure in that the lane rope buoys 100A are wider than the lane rope buoys 100 of the first embodiment, but are the same as the lane rope buoys 100 of the first embodiment in other aspects, and therefore detailed description thereof is omitted.

[0059] like Figure 8 As shown in (a), a plurality of lane rope buoys 100 are attached to the rope R connected to the outer wall 910 of the swimming pool. On the other hand, a plurality of lane rope buoys 100A are attached to the rope R near the center 920 of the swimming pool. The configuration of the lane rope buoy 100A is the same as that of the lane rope buoy 100, but the overall length of the lane rope buoy 100A, that is, the width L3 along the extending direction of the rope R is wider than the width L4 of the lane rope buoy 100. Furthermore, since the lane rope buoy 100A and the lane rope buoy 100 differ only in width, when attached to the rope R, the width L2 of the gap between adjacent lane rope buoys 100A is equal to the width L2 of the gap between adjacent lane rope buoys 100.

[0060] Therefore, if Figure 8 As shown in (b), near the center 920 of the swimming pool, since the width L3 of the lane rope buoy 100A is wide, the number of lane rope buoys 100A that can be arranged per unit length along the rope R is reduced, and the gaps between the lane rope buoys 100A are reduced. Figure 8 As shown in (a), on the side of the rope R connected to the outer wall 910 of the swimming pool, since the width L4 of the lane rope buoy 100 is narrow, the number of lane rope buoys 100 that can be configured in each unit length along the rope R increases, and the gaps between the lane rope buoys 100 become more.

[0061] To be more specific, Figure 8 As shown in (b), near the center 920 of the swimming pool, there is a gap of width L2 between two lane rope buoys 100A in each unit length L5 along the rope R. Figure 8As shown in (a), on the rope R side connected to the outer wall 910 of the swimming pool, there is a gap of width L2 between five lane rope buoys 100 in each unit length L5 along the rope R.

[0062] So, like Figure 8 As shown in (b), near the center 920 of the swimming pool, since the width L3 of the lane rope buoys 100A is wide, the gaps between the lane rope buoys 100A are reduced, so that the waves are not easy to overflow to the adjacent lanes, and the waves are eliminated by the lane rope buoys 100A. Figure 8 As shown in (a), on the rope R side connected to the outer wall 910 of the swimming pool, since the width L4 of the lane rope buoy 100A is narrow, the gaps between the lane rope buoys 100A are increased, so that waves are easily overflowed to the adjacent lanes, and the lane rope buoy 100A itself is easy to rotate, so the wave-breaking performance is also ensured. As a result, the shaking or turbulence of the water surface is reduced, and it is not easy to be hit by the waves generated by itself after turning back, and it becomes easy to swim after turning back.

[0063] In addition, if Figure 8 As shown in (a), near the outer wall 910 of the swimming pool 900, lane rope buoys 100A with a width of L4 are continuously arranged in a relatively long range, but it is not limited to this. Near the outer wall 910 of the swimming pool 900, as long as the width L4 of at least a part of the lane rope buoys 100A is narrowed, the lane rope buoys other than the lane rope buoys 100A with a width of L4 may be of any width and structure. For example, the lane rope buoys other than the lane rope buoys 100A with a width of L4 may be configured to be wider than the width L4, or to be of a different type. The reason is that even in this case, if the width L4 of at least a part of the lane rope buoys 100A is narrowed, the waves are likely to overflow to the adjacent lanes, and the lane rope buoys 100A themselves are likely to rotate, thereby ensuring the wave-breaking performance, reducing the shaking or turbulence of the water surface, and making it easier to swim after turning back. Similarly, if Figure 8 As shown in (b), near the center 920 of the swimming pool 900, lane rope buoys 100A with a width L3 are continuously arranged in a relatively long range, but it is not limited to this. As long as the width L3 of at least a part of the lane rope buoys 100A is widened, the lane rope buoys other than the lane rope buoys 100A with a width L3 may be of any width and structure.

[0064] <Implementation method 3> Secondly, refer to Fig. 9 , a swimming lane rope buoy 100B according to a third embodiment of the present invention will be described. Fig. 9The lane rope buoy 100B of the third embodiment of the present invention is identical to the lane rope buoy 100 of the first embodiment except for the number of wing plates 120B, so detailed description thereof will be omitted.

[0065] like Fig. 9 As shown, in the lane rope buoy 100B, a total of five wing plates 120B protruding from the side surface 111B of the cylindrical portion 110B in parallel with the rope R are provided. By reducing the number of wing plates 120B, when the lane rope buoy 100B floats on the water, the lane rope buoy 100B becomes easier to rotate than the lane rope buoy 100 of the first embodiment which has a total of six wing plates 120. In addition, only one of the lane rope buoy 100B of the third embodiment having different numbers of wing plates and the lane rope buoy 100 of the first embodiment may be attached to the rope R, or the lane rope buoy 100B of the third embodiment and the lane rope buoy 100 of the first embodiment may be attached to the rope R in a mixed manner. In addition, the lane rope buoy 100B of the third embodiment has a total of five wing plates 120B, but the present invention is not limited thereto, and the number of wing plates 120B may be set arbitrarily. Furthermore, in the present invention, swimming lane rope buoys having different numbers or types of wings may be used in combination.

[0066] Secondly, refer to Fig.10 and Fig.11 , the swimming lane rope buoy 100C and the spacer 800C according to the fourth embodiment of the present invention are described. Fig.10 This is a perspective view of the entirety of the lane rope buoy 100C and the spacer 800C. Fig.11 (a) is a side view of a state where a spacer 800C is installed on a lane rope buoy 100C. Fig.11 (b) is an AA cross-sectional view and is a cross-sectional view of the periphery of the cylindrical portion 110C. In addition, the configuration of the lane rope buoy 100C of the fourth embodiment of the present invention is different only in the shape of the periphery of one outer end 112C and the other outer end 113C of the cylindrical portion 110C, and the configuration of the lane rope buoy 100 of the first embodiment is the same as that of the lane rope buoy 100, so a detailed description is omitted.

[0067] In the lane rope buoy 100C, the outer end 122C of the wing plate 120C near the cylindrical portion 110C is recessed further inward than the outer end 112C of the cylindrical portion 110C to form a recessed portion 125C. In addition, the outer end 122C of the wing plate 120C near the cylindrical portion 110C is recessed further inward than the outer end 113C of the cylindrical portion 110C to form a recessed portion 125C. By recessing inward, a space can be formed so that the spacer 800C installed in the adjacent lane rope buoy can abut against one outer end 112C or the other outer end 113C of the cylindrical portion 110. The spacer 800C installed in the adjacent lane rope buoy rests on the outer end 122C of the wing plate 120C to prevent the spacer 800C from tilting, and the lane rope buoy 100C can be arranged in a neat arrangement.

[0068] In addition, one outer end 112C and the other outer end 113C of the cylindrical portion 110C of the lane rope buoy 100C are both arranged on the same plane as the outer end 122C of the wing plate 120C, but the present invention is not limited thereto, and one outer end 112C and the other outer end 113C of the cylindrical portion 110C of the lane rope buoy 100C may protrude further than the outer end 122C of the wing plate 120C. The protrusion amounts may be the same or different.

[0069] In addition, the spacer 800C is formed of a synthetic resin material and has a substantially cylindrical shape. It is surrounded by an outer edge portion 801C on the outside and has an insertion portion 820C having a through hole 810C. The insertion portion 820C extends linearly over both end portions in a manner that allows a metal wire to be inserted. In addition, the insertion portion 820C is inserted into the cylindrical portion 110C, and the spacer 800C is installed on the buoy 100C for a swimming lane rope. The spacer 800C has a protrusion 830C on the end side of the insertion portion 820C. The protrusion 830C is not inserted into the cylindrical portion 110C but protrudes outward from the cylindrical portion 110C. In addition, the outer diameter of the protrusion 830C is larger than the outer diameter of the insertion portion 820C, and can be formed in a substantially T-shape when viewed from the side. In addition, the structure of the spacer 800C is similar to Figure 4 The spacer 800 shown is different but has the same effect. Figure 4 The spacers 800 shown are substantially the same, and the spacers 800C are disposed between adjacent lane rope buoys to adjust the width of the gaps between the lane rope buoys.

[0070] Furthermore, by attaching the spacer 800C to the lane rope buoy 100C, the shaft portion of the lane rope buoy 100C can be prevented from being split when the lane rope buoy 100C is stored and wound on a reel. Fig.11As shown in (b), the impact strength or compression strength from the inner surface 802C side of the insertion portion 820C of the spacer 800C toward the outer edge 801C is stronger than the strength from the inner surface 114C side of the cylindrical portion 110C of the swimming lane rope buoy 100C toward the outer surface 115C side. In addition, by increasing the curvature radius of the outer edge 811C of the through hole 810C of the spacer 800C, it is possible to prevent the spacer 800C from being scratched by the wire, and to prevent the spacer 800C from falling off from the cylindrical portion 110C of the swimming lane rope buoy 100C when the swimming lane rope buoy 100C is wound on a reel for storage.

[0071] By making the wall thickness of the insertion portion 820C of the spacer 800C thinner than the wall thickness of the cylindrical portion 110C of the lane rope buoy 100C, when the spacer 800C is attached to the lane rope buoy 100C, the step 108C between the inner surface 802C of the insertion portion 820C of the spacer 800C and the inner surface 114C of the cylindrical portion 110C of the lane rope buoy 100C is small, and the wire is not easily caught. Furthermore, in the cylindrical portion 110C, the inner diameter is partially increased at the portion where the insertion portion 820C of the spacer 800C is inserted, and a concave stripe portion 116C is formed in a shape that is concave from the inner surface 114C of the cylindrical portion 110C. Therefore, when the insertion portion 820C of the spacer 800C is inserted into the groove 116C, the step 108C between the inner surface 802C of the insertion portion 820C of the spacer 800C and the inner surface 114C of the cylindrical portion 110C of the lane rope buoy 100C becomes smaller, and the wire is less likely to get stuck. In addition, the step 109C between the inner surface 114C of the cylindrical portion 110C and the groove 116C is larger than the step 108C.

[0072] In addition, when the rope is stretched, the inner diameter of the cylindrical portion 110C near the center of the lane rope buoy 100C and the inner diameter of the spacer 800C when the spacer 800C is installed can be located on a straight line (the same plane), and the rope becomes less likely to be hooked. In addition, when the spacer 800C is installed on the side of one outer end of the cylindrical portion 110C, the lane rope buoys 100C are arranged and the rope is stretched, the rope hits the inner surface of each spacer 800C, and since the rope is less likely to hit the cylindrical portion 110C of the lane rope buoy 100C, the lane rope buoy 100C is less likely to be damaged. In addition, the structure of one outer end 112C side of the cylindrical portion 110C and the other outer end 113C side is symmetrical on the left and right. Moreover, in Fig.10 and Fig.11 In the figure, the spacer 800C is installed only on the side of one outer end 112C of the cylindrical portion 110C, but the present invention is not limited thereto. The spacer 800C may be installed only on the side of the other outer end 113C of the cylindrical portion 110C, or may be installed on both the outer end 112C and the outer end 113C.

[0073] Since the lane rope buoy 100C and the spacer 800C are both made of polyethylene, they do not need to be sorted when discarded, so they are easy to recycle.

[0074] The cylindrical portion 110C of the lane rope buoy 100C is arranged so that the diameter of the cylindrical portion 110C increases from the center 117C to the outer end 118C. Therefore, it is easy to fall off from the mold during molding. In addition, since the cylindrical portion 110C is arranged so that the diameter of the cylindrical portion 110C increases from the center 117C toward the outer end 118C, it is not easy to get stuck when the lane rope buoy 100C is installed on the wire, etc., so the workability is improved.

[0075] <Implementation method 5> Next, Embodiment 5 which embodies the present invention will be described according to the drawings. Fig.12 The entire buoy 10 of the present embodiment 5 is shown. In addition, the buoy 10 is obtained by integrally molding a foamed synthetic resin material by injection molding, and a material such as a float on water is used to quickly dissipate waves propagating on the surface side of the water stored in the swimming pool or in the water (hereinafter collectively referred to as the "water surface") . As a specific example of the material, polypropylene or polyethylene is included, and the specific gravity of the entire buoy is less than 1. However, when a float is attached to the buoy, the specific gravity of the buoy portion other than the float may be greater than 1.

[0076] like Fig.12 and Fig.13 As shown, the buoy 10 has a cylindrical portion 12 for inserting a rope 11 (indicated virtually) at its central position. The cylindrical portion 12 has an opening 12A extending along the extension direction (arrow 11A direction) of the rope 11 stretched in the swimming pool. By inserting the rope 11 into the opening 12A, the buoy 10 can be mounted on the rope 11, so the cylindrical portion 12 functions as a central mounting portion. Here, the buoy 10 has a point-symmetrical structure based on the center point existing in the cylindrical portion 12. In order to conveniently explain the structure of one side (the left side of the center line 10A), the same symbols are marked for the same structure, and the description of the opposite side (the right side of the center line 10A) is omitted.

[0077] A plurality of (six in this embodiment) wing plates 13 are extended from the outside of the cylindrical portion 12. Specifically, each wing plate 13 is extended only by a predetermined length in the direction of arrow 11A, and extends outward every 60 degrees from the outside of the cylindrical portion 12. A connecting portion 14 connected to each other is provided on each wing plate 13, and a circumferential outer wall portion 15 is formed on the outer edge of the six wing plates 13 to connect the wing plates 13 to each other. The outer wall portion 15, the adjacent connecting portions 14, the adjacent pair of wing plates 13 and the cylindrical portion 12 form a small space (hereinafter referred to as a "separate space" 16) that divides the entire space in the buoy 10 into approximately six equal parts. In addition, the portion connecting the cylindrical portion 12 and the wing plate 13 can be appropriately changed, and the wing plate 13 can be in a form that does not contact the outside of the cylindrical portion 12. In this case, the separate space 16 is formed by the adjacent pair of wing plates 13, the adjacent connecting portions 14 and the adjacent outer wall portions 15.

[0078] In addition, the outer wall 15 is provided with a blocking portion 17 for blocking waves propagating from the swimming pool water surface D1 outside the buoy 10, and the blocking portion 17 is formed with an opening 18 for guiding the waves propagating from the swimming pool water surface D1 into the separate space 16. Specifically, Fig.13 As shown, the blocking portion 17 facing the opening 18 forms a curve along the outer surface of the outer wall portion 15, and further forms the size of the inflow of water entering from the swimming pool water surface D1 on the circumferential surface from the wing plate 13 toward the adjacent wing plate 13. Here, by forming the opening 18 with a large inflow portion E1 with a large inflow and a small inflow portion E2 with a small inflow, the surrounding area of ​​the blocking portion 17 connected to the opening 18 is curved in a manner that the inflow of water from the opening 18 between the large inflow portion E1 and the small inflow portion E2 gradually changes. Furthermore, when the amount of water introduced into the separate space 16 is sufficiently large, the kinetic energy of the waves of the water transferred into the separate space 16 imparts kinetic energy to the pair of wing plates 13, the adjacent connecting portions 14, and the adjacent outer wall portions 15, thereby causing the entire buoy 10 to shake. At this time, the ratio of the opening 18 to the blocking portion 17 can be appropriately set to achieve efficient shaking.

[0079] In addition, three concentric water openings 19 are formed in the connection part 14 connecting the wing plate 13 and the outer wall part 15, and these water openings 19 can pass the waves introduced into the separate space 16. In this case, the water in the separate space 16 on the left is transported to the separate space 16 on the right, and in addition, water is also passed from the separate space 16 on the right to the separate space 16 on the left. In addition, as a structure related to the connection part 14 and the water openings 19, the width of the connection part 14 (that is, the width of the water blocking) and the water passing width of the three water openings 19 can be appropriately set. That is, the ratio can be arbitrarily changed by fixing any one of the width of the connection part 14 and the water passing width of the three water openings 19 and changing the other. For example, the water opening 19 has an opening of 20 to 60%, preferably 25 to 50%, and more preferably 30 to 45% relative to the connection part 14. If the water passage 19 is too open relative to the connecting portion 14, the strength of the entire buoy is reduced, and it may be damaged or deformed when packaged or rolled up during storage. As a result, the inflow of water introduced into the separate space 16 can be adjusted to an appropriate inflow. By appropriately changing the width of the connecting portion 14 and the water passage width of the water passage 19 as described above, the amount of water introduced into the separate space 16 is different, and the kinetic energy of the waves propagating with the water is different, so the shaking amount of the buoy 10 changes, and the degree of wave attenuation of the waves propagating on the water surface changes. In addition, the width of the connecting portion 14 and the position and shape of the water passage 19 can also be appropriately changed beyond this embodiment.

[0080] like Fig.14 As shown, a protrusion 20 is formed on the connection portion 14 for guiding waves into the space inside the buoy 10 through the above-mentioned opening 18. The protrusion 20 functions as a guide for guiding waves in the separate space 16, and a conical surface 20A is formed on a part of the protrusion 20 (in this case, a part on the left and right of the protrusion 20), and the conical surface 20A can guide the waves propagating in the separate space 16 to the water outlet 19. In addition, as long as the protrusion 20 plays a guiding function for guiding waves, it can also be changed to a shape other than a conical surface. In detail, the shape of the protrusion 20 can be arbitrarily changed by changing the height, position and slope of the conical surface of the protrusion 20 that define the shape of the protrusion 20. For example, by arranging the protrusion 20 at the center of the connection portion 14, the amount of water flowing along the surface of the protrusion 20 can be evenly distributed. In addition, for example, the position of the protrusion 20 can be close to one side (one side) in the plurality of water passages 19. Furthermore, the protrusion 20 can also connect adjacent wing plates 13 to each other or become 80 to 100%, preferably 85 to 95% of the length between the wing plates 13. In addition, in order to improve the wave-breaking capability, the height of the protrusion 20 can also be set to any height in the direction of the arrow 11A. In addition, a protruding plate 21 extending parallel to the arrow 11A direction is provided at a position opposite to the opening 18 in the wing plate 13 for reflecting and guiding the waves entering the separate space 16. In this case, the protruding plate 21 is provided at a position opposite to the adjacent wing plate 13, and is connected to the protruding portion 20 located on the outer peripheral side in the plurality of connecting portions 14. The structure of the protruding portion 20 and the protruding plate 21 is used to guide the waves in the separate space 16 to the water passage 19, and the thickness of the protruding plate 21 is preferably set to be substantially the same as the thickness of the protruding portion 20. For example, the wall thickness of the protruding plate is the same as or within 1.5 times that of the wing plate 13, and the width is the same as the length of the wing plate 13.

[0081] In the case of the above-mentioned buoy 10, the blocking portion 17 blocks the waves propagating from the swimming pool water surface D1 outside the buoy 10 and reflects them outside the buoy 10. On the other hand, when the waves propagating from outside the buoy 10 are introduced into the separate space 16 through the opening 18, they hit the wing plate 13, the connecting portion 14, the protruding plate 21, etc. in the separate space 16, thereby generating turbulence in the water in the separate space 16, and the turbulence causes the buoy 10 attached to the rope 11 to shake, rotate, displace, etc. (hereinafter referred to as "shaking, etc."). Furthermore, the waves reflected by hitting the wing plate 13 and the connection part 14 are discharged from the opening 18 and the water passage 19 into the separate space 16 next to the common connection part 14 and the water passage 19. As a result, the waves further generate turbulence by hitting the wing plate 13, the protrusion 20 and the protruding plate 21 in the separate space 16 next to it, and the turbulence causes the buoy 10 attached to the rope to shake, rotate, displace, etc. (hereinafter referred to as "shaking, etc."). The energy of the waves transmitted to the separate space 16 in this way generates turbulence in the water in the separate space 16, and the energy generating the turbulence is consumed in the buoy 10, and as a result, the waves caused by the swimmer are eliminated by the shaking of the buoy 10, etc. In addition, the area of ​​the opening 18 is 40-70%, preferably 50-60%, of the outer wall 15, and the blocking portion 17 is 30-60%, preferably 40-50%, of the outer wall 15. By making the area of ​​the opening 18 larger than the blocking portion 17, the waves are easily turbulent and consumed. Among the waves entering from the opening 18, the waves entering from the opening 18 and the waves hitting the wing plate 13 and rebounding generate turbulence and break the waves, and turbulence is generated on the back side of the blocking portion 17 and break the waves. By making the area of ​​the opening 18 larger than the blocking portion 17, the amount of water increases, and the waves generate complex turbulence and are consumed.

[0082] In addition, in the connection part 14 having the protrusion 20, the waves propagating into the independent space 16 can be smoothly guided to the water passage 19, whereas, in the case where the protrusion 20 is not formed, the propagating waves may not be smoothly guided to the water passage 19. Thus, the protrusion 20 plays a function of guiding the waves introduced into the independent space 16 through the opening 18 to the water passage 19.

[0083] In addition, in the connection portion 15A connecting the outer wall portion 15 and the wing plate 13, as shown in FIG. Fig.15 As shown, at the portion cut in the vertical direction D2 relative to the water surface D1 and in the direction in which the rope extends (the direction of the arrow 11A), a transcending portion (a portion over which waves pass) 22 is formed on one side, and a wave-breaking portion (a portion over which waves do not pass) 23 is formed on the opposite side. Specifically, near the connection portion 15A, the one side and the opposite side of the wing plate 13 are made different in shape from each other, and the transcending portion 22 (in this case, a shape different from the wave-breaking portion 23 and without a convex shape) is roughly flush with the water surface on the swimming pool water surface side D1A, so that waves can easily pass over it, while the wave-breaking portion 23 is formed in a convex shape (a thicker shape) toward the water, so that waves in the water cannot pass over the wave-breaking portion 23.

[0084] In this case, the shapes of the outer ends of the transcending portion 22 and the outer ends of the wave-breaking portion 23 are roughly consistent with the circumferential direction of the outer wall portion 15, and the outer ends of the wave-breaking portion 23 are roughly in the same plane as the outer wall portion 15. In addition, from the perspective of lightweight, the thickness of the wave-breaking portion 23 can be set to be thinner than the thickness of the outer wall portion 15. In addition, the shape, position, size, thickness, etc. of the transcending portion 22 and the wave-breaking portion 23 should not be limited to this form, and can be appropriately changed. In addition, the height of the transcending portion 22 that the wave passes over only needs to be lower than the height of the wave-breaking portion 23. When the buoy 10 is installed on the rope, depending on the stretching of the rope, the transcending portion 22 of the buoy 10 may sink from the water surface side D1A of the swimming pool, but even in this case, the same effect can be achieved.

[0085] As a result, when the wing 13 is placed on the water surface D1, if the overpassing portion 22 is located on the water surface side D1A and the wave-breaking portion 23 is located in the water D1B, when the waves propagating from outside the buoy 10 are introduced into the separate space 16, they easily pass over the overpassing portion 22 and enter the separate space 16, and are reflected by the wave-breaking portion 23. With such a configuration, the waves propagating from the swimming pool water surface D1 outside the buoy 10 easily cause the buoy 10 to shake, etc. In addition, the wall thickness of the convex wave-breaking portion 23 is increased to ensure the strength of the entire buoy 10 and prevent damage during operation of the buoy 10. Fig.12In the separate space 16 of the common water outlet 19 on the left and right sides shown, the protruding portion 22 of the buoy 10 on the left side becomes the water surface side D1A, and the wave-breaking portion 23 becomes the underwater side D1B. Conversely, the protruding portion 22 of the buoy 10 on the right side becomes the underwater side D1B, and the wave-breaking portion 23 becomes the water surface side D1A. This structure is adopted from the viewpoint of eliminating the complexity of determining the direction of the buoy 10 when the buoy 10 is installed on the rope. Here, when the transcending portion 22 is arranged on the side of the portion E1 with a large inflow and the wave-breaking portion 23 is arranged on the side of the portion E2 with a small inflow, waves propagating on the water surface D1 can easily pass over the transcending portion 22 from the side of the portion E1 with a large inflow and enter more into the separate space 16, while the wave-breaking portion 23 on the side of the portion E2 with a small inflow is more reflected, thereby having an effect of improving the wave-breaking function by utilizing the shaking of the buoy 10.

[0086] As described above, even if the overpassing portion 22 of one (right) buoy 10 becomes the underwater D1B side and the wave-breaking portion 23 becomes the water surface D1A, since the overpassing portion 22 of the opposite (left) buoy 10 becomes the water surface D1A and the wave-breaking portion 23 becomes the underwater D1B side, the waves propagating from the swimming pool water surface D1 outside the buoy 10 can easily shake the buoy 10, etc. When the above-mentioned structure is adopted, the waves can be quickly dissipated, and in order to quickly conduct the swimming competition, the next swimmer can start the competition after a short wave dissipation time after the previous swimmer has finished the competition.

[0087] Fig.19 The photo shown shows the situation where the waves propagating on the surface D1 of the swimming pool are not damped just after the swimmer has finished swimming in the lane. Fig. 20 The photo shown shows a situation where after the swimmer has finished swimming in the lane, the waves are eliminated by the buoys 10 installed on the ropes dividing the lane, and the water surface D1 becomes stable. The inventors carefully observed the conditions of the water surface D1 and studied many images, and the following verification results were obtained. That is, the volume of the single space 16 ( Fig.16 The colored part) is set as A1, and the total area of ​​the water outlet 19 ( Fig.18 The colored portion) is set as B1, and the total area of ​​the opening 18 ( Fig.17 The colored part of the image is focused on C1. In this case, the volume of the separate space 16 is approximately one sixth of the total space (excluding the wall portion) in the buoy 10. The total area B1 of the water openings 19 can be calculated by adding up the areas of the three concentric water openings 19. Furthermore, the total area C1 of the openings 18 can be calculated by subtracting one sixth of the total area of ​​the blocking portion 17 from one sixth of the total peripheral area of ​​the buoy 10.

[0088] Moreover, when the ratio of A1 (volume of the separate space 16) to B1 (total area B1 of the water passage 19) is 1000:5 or less (below the lower limit), it can be seen that the attenuation of the waves propagating in the separate space 16 is small, and the attenuation of the waves in the separate space 16 is not sufficient. In addition, when the ratio of A1 to B1 is 1000:15 or more (above the upper limit), it can be seen that the attenuation of the waves propagating in the separate space 16 is small, and the attenuation of the waves in the separate space 16 is not sufficient. In addition, the so-called "wave attenuation is not sufficient" refers to a situation where the wave is not eliminated before a predetermined time (e.g., 1 minute and 30 seconds) has passed after the swimmer has swum, as one of the judgment criteria. On the other hand, the so-called "wave attenuation is sufficient" refers to a situation where the wave is eliminated before a predetermined time (e.g., 1 minute and 30 seconds) has passed after the swimmer has swum. As a result, it was found that the allowable value of the ratio of A1 to B1, which was above the lower limit (1000:5) and below the upper limit (1000:15), was consistent with the allowable value of above the lower limit and below the upper limit based on the wave-breaking related standard (whether or not a prescribed time has passed after the swimmer has finished swimming). In addition, when the ratio of A1 to B1 was within the allowable value of above the lower limit and below the upper limit, it was noted that the wave breaking was sufficient. As a result, it was found that the wave breaking could be further improved if further verification was applied to the ratio of A1 to B1, and various trials and errors were performed. For example, the specified time after the swimmer swims can be set to a shorter specified time, such as 1 minute 20 seconds, in addition to the above-mentioned 1 minute 30 seconds (wave-breaking related benchmark). The shorter the time after the swimmer swims, the higher the wave-breaking function (wave-breaking function). Furthermore, when the prescribed time after the swimmer has swum is set to 1 minute 20 seconds, if the ratio of A1 to B1 is within the permissible value of (1000:6) or more (above the lower limit) and (1000:10) or less (below the upper limit), it can be seen that the wave is sufficiently eliminated. In addition, as a criterion related to wave elimination, other criteria (official criteria or internal criteria, etc.) may be used in addition to whether the prescribed time after the swimmer has swum.

[0089] In addition, as a further study of the conditions of "wave attenuation is not sufficient" and "wave attenuation is appropriate", the following criteria can be found. That is, similar to the above judgment criteria, when the ratio of A1 (volume of the independent space 16) to C1 (total area of ​​the opening 18) is (1000:15) or less (below the lower limit), it can be seen that the attenuation of the waves propagating in the independent space 16 is small, and the attenuation of the waves in the independent space 16 is not sufficient. In addition, when the ratio of A1 to C1 is (1000:25) or more (above the upper limit), it can be seen that the attenuation of the waves propagating in the independent space 16 is small, and the attenuation of the waves in the independent space 16 is not sufficient. As a result, it was found that the allowable value of the ratio of A1 to C1, which was above the lower limit (1000:15) and below the upper limit (1000:25), was consistent with the allowable value of above the lower limit and below the upper limit based on the wave-breaking related standard (whether or not a prescribed time has passed after the swimmer has swum). In addition, when the ratio of A1 to C1 was within the allowable value of above the lower limit and below the upper limit, it was noted that the wave breaking was sufficient. As a result, it was found that the wave breaking could be further improved if further verification was performed on the ratio of A1 to C1, and various trials and errors were performed. For example, when the ratio of A1 to C1 is set to 1 minute 20 seconds (wave-absorption-related standard) after the swimmer has swum, if it is within the permissible value of 1000:17 or more (above the lower limit) and 1000:23 or less (below the upper limit), it can be known that the wave absorption is sufficient. In addition, as the wave absorption-related standard, in addition to whether the prescribed time after the swimmer has swum, other standards (official standards or internal standards, etc.) may be used. As described above, according to the buoy 10 of this embodiment, by quickly consuming the energy of waves on the water surface D1 generated by swimmers or the like swimming in the swimming lane of a swimming pool, it is possible to eliminate the waves propagating on the water surface D1 in a short time.

[0090] In detail, Fig.19 and Fig. 20 As shown in the photo, the swimming pool surface is divided into swimming lanes by pulling ropes, and multiple Fig.12 The buoy shown can provide a swimming pool for swimming competitions with high wave-breaking function. In addition, the present invention is not limited to the above-mentioned embodiment, and various changes can be made. It is not necessary to have six wing plates, and for example, it can also be a structure with five wing plates. In addition, the number of water holes provided in the connection part can be other than three, and in addition to the concentric circle shape, it can also be a plurality of circular holes. In addition, a float can be appropriately installed on the buoy to adjust the position of the buoy in the floating state. In addition, when a plurality of buoys are mounted on a rope, a spacer may be installed between the buoys to ensure that the buoys are spaced apart so that the buoys can slide well with each other. In this case, by installing the spacer close to the cylindrical portion of the buoy, the spacing between the adjacent buoys can be maintained. Of course, it is desirable to appropriately set the spacing between the buoys to prevent waves caused by swimmers in the adjacent lanes from propagating between the buoys. In addition, through Fig.12 The buoy has the above-mentioned point-symmetrical structure, and the left and right buoys have the same structure. As a modification example, it can also be an asymmetric structure other than the point-symmetrical structure.
