A buoy (100) for a lane rope according to the present invention is attached to a rope (R) via a cylindrical section (200) to divide each lane of a swimming pool, is formed from a synthetic resin material, and has formed therein a recessed support section (120) capable of supporting a part of the body.

Description

Technical Field

[0001] The present invention relates to a buoy for a swimming lane rope arranged in a swimming pool or the like. 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 cylindrical portion having a cylindrical shape as a whole and a rope inserted through the center portion; a plurality of wing plates protruding parallel to the rope; and an outer peripheral wall connected to surround the wing plates. Waves generated by people in the swimming pool of each lane are brought into the lane rope buoy and dissipated by the wing plates or the outer peripheral wall.

[0003] However, since the outer side of the lane rope buoy disclosed in Patent Document 1 is a cylindrical shape surrounded by an outer peripheral wall, it is difficult to hold it with hands or put one's arms around it. People in the swimming pool, such as those swimming, walking, or playing in the swimming pool, cannot take a rest by holding on to the lane rope buoy.

[0004] In addition, regarding the lane rope buoy disclosed in Patent Document 2, when a person in the swimming pool holds the buoy with his hand or hangs his arm on the buoy while standing, resting, or about to drown in the swimming pool, the buoy easily rotates, and thus may slip off the lane rope buoy, which is quite dangerous. Therefore, people in the swimming pool, such as those swimming, walking, or playing in the swimming pool, cannot rest in peace by holding the lane rope buoy. Prior art literature Patent Literature

[0005] Patent Document 1: Japanese Registered Utility Model No. 3055245 Patent document 2: Japanese Patent Utility Model Publication No. 50-42584 Summary of the invention Technical Problems to be Solved by the Invention

[0006] In view of the above problems, the present invention provides a swimming lane rope buoy, which allows people in a swimming pool to rest easily by holding it with their hands or hanging their arms. Solutions to the problem

[0007] In order to solve the above problems, a lane rope buoy according to claim 1 of the present invention is attached to a rope via a cylindrical portion to divide each lane of a swimming pool, is formed of a synthetic resin material, and has a concave support portion capable of supporting a part of the body.

[0008] According to the above features, people in the swimming pool can simply take a rest by holding the concave supporting part with their hands or by placing their arms on the concave supporting part.

[0009] Furthermore, in the swimming lane rope buoy according to the second aspect of the present invention, the swimming lane rope buoy has an outer diameter in which a maximum diameter portion is formed where the center side of the concave support portion is smaller than the outer side and the outer diameter is the largest.

[0010] According to the above features, when a person in the swimming pool holds the concave support portion with his hand or puts his arm on the concave support portion, the hand or arm is not likely to deviate from the concave support portion, and the concave support portion can stably support the person in the swimming pool.

[0011] Furthermore, in the swimming lane rope buoy according to the third aspect of the present invention, a soft synthetic resin material is used for blow molding.

[0012] According to the above features, the lane rope buoy is not easily deformed, and people in the swimming pool can easily hold the concave supporting portion with their hands or put their arms on the concave supporting portion.

[0013] Furthermore, in the swimming lane rope buoy according to claim 4 of the present invention, the cylindrical portion is composed of a hard material and a soft material softer than the hard material, and the soft material is arranged on a side facing the rope.

[0014] According to the above features, it is easy for people in the swimming pool to hold the concave support part with their hands or put their arms on the concave support part. Furthermore, according to the above features, since the friction with the rope and the cylindrical part becomes large, it is possible to suppress the movement of the lane rope buoy around the rope (specifically, the rotation of the lane rope buoy around the rope and the lateral displacement of the lane rope buoy along the length direction of the rope). As a result, people in the swimming pool who swim in each lane can hold the lane rope buoy in a stable posture and rest.

[0015] Furthermore, in the swimming lane rope buoy according to claim 5 of the present invention, the cylindrical portion is composed of a hard material and a soft material softer than the hard material, and the soft material is arranged on a side facing the rope.

[0016] According to the above features, it is easy for people in the swimming pool to hold the concave support part with their hands or put their arms on the concave support part. Furthermore, according to the above features, since the friction with the rope and the cylindrical part becomes large, it is possible to suppress the movement of the lane rope buoy around the rope (specifically, the rotation of the lane rope buoy around the rope and the lateral displacement of the lane rope buoy along the length direction of the rope). As a result, people in the swimming pool who swim in each lane can hold the lane rope buoy in a stable posture and rest.

[0017] Furthermore, in the swimming lane rope buoy according to claim 6 of the present invention, the cylindrical portion is made of a soft material.

[0018] According to the above features, it is easy for people in the swimming pool to hold the concave support part with their hands or put their arms on the concave support part. Furthermore, according to the above features, since the friction with the rope and the cylindrical part becomes large, it is possible to suppress the movement of the lane rope buoy around the rope (specifically, the rotation of the lane rope buoy around the rope and the lateral displacement of the lane rope buoy along the length direction of the rope). As a result, people in the swimming pool who swim in each lane can hold the lane rope buoy in a stable posture and rest.

[0019] Furthermore, in the swimming lane rope buoy according to claim 7 of the present invention, the cylindrical portion is made of a soft material.

[0020] According to the above features, it is easy for people in the swimming pool to hold the concave support part with their hands or put their arms on the concave support part. Furthermore, according to the above features, since the friction with the rope and the cylindrical part becomes large, it is possible to suppress the movement of the lane rope buoy around the rope (specifically, the rotation of the lane rope buoy around the rope and the lateral displacement of the lane rope buoy along the length direction of the rope). As a result, people in the swimming pool who swim in each lane can hold the lane rope buoy in a stable posture and rest.

[0021] Furthermore, in the swimming lane rope buoy according to claim 8 of the present invention, rotation inhibiting members are attached to both ends of the cylindrical portion, and the rotation inhibiting members are made of a softer material than a material constituting the cylindrical portion.

[0022] According to the above features, it is easy for people in the swimming pool to hold the concave support part with their hands or put their arms on the concave support part. Furthermore, according to the above features, since the friction with the rope and the rotation suppression member becomes large, it is possible to suppress the movement of the lane rope buoy around the rope (specifically, the rotation of the lane rope buoy around the rope and the lateral displacement of the lane rope buoy along the length direction of the rope). As a result, people in the swimming pool who swim in each lane can hold the lane rope buoy in a stable posture and rest.

[0023] Furthermore, in the swimming lane rope buoy according to claim 9 of the present invention, rotation inhibiting members are attached to both ends of the cylindrical portion, and the rotation inhibiting members are made of a softer material than a material constituting the cylindrical portion.

[0024] According to the above features, it is easy for people in the swimming pool to hold the concave support part with their hands or put their arms on the concave support part. Furthermore, according to the above features, since the friction with the rope and the rotation suppression member becomes large, it is possible to suppress the movement of the lane rope buoy around the rope (specifically, the rotation of the lane rope buoy around the rope and the lateral displacement of the lane rope buoy along the length direction of the rope). As a result, people in the swimming pool who swim in each lane can hold the lane rope buoy in a stable posture and rest.

[0025] In order to solve the above-mentioned problems, in the lane rope buoy of scheme 10 of the present invention, the buoy is installed on the rope via a cylindrical portion to divide the swimming lanes of the swimming pool, is formed of a synthetic resin material, and a locking portion for locking the rope is arranged on the inner side of the above-mentioned cylindrical portion, and the above-mentioned locking portion forms a concave and convex shape in the circumferential direction of the above-mentioned cylindrical portion.

[0026] According to the above features, the stopper portion having a concave-convex shape prevents the rope from moving in the cylindrical portion, effectively preventing the lane rope buoy from rotating. Therefore, people in the swimming pool can rest assured by easily holding the lane rope buoy with their hands or putting their arms on the lane rope buoy.

[0027] Furthermore, in the swimming lane rope buoy according to claim 11 of the present invention, the locking portion includes an inclined wall that inclines inwardly as it becomes farther away from the center of the cylindrical portion.

[0028] According to the above features, when a person in the swimming pool holds the lane rope buoy with his hand or puts his arm on the lane rope buoy, the lane rope buoy is pushed downward as a whole and moves, and the inclined wall is elastically deformed toward the inside, so that the contact area with the rope increases, and the rope is strongly caught by the catch portion, which effectively prevents the lane rope buoy from rotating. Therefore, the person in the swimming pool can rest at ease by easily holding the lane rope buoy with his hand or putting his arm on the lane rope buoy.

[0029] Furthermore, in the swimming lane rope buoy according to claim 12 of the present invention, the cylindrical portion is blow-molded using a synthetic resin material, and a portion of the wall thickness of the cylindrical portion is thinner at the end side than at the center side.

[0030] According to the above-mentioned feature, since the end side with a thinner wall thickness can be flexibly elastically deformed, the rope and the locking portion of the end side can be easily locked, and the locking portion and the rope are in closer contact. Therefore, the rope is strongly locked by the locking portion, and the lane rope buoy can be effectively prevented from rotating. Therefore, the person in the swimming pool can rest at ease by easily holding the lane rope buoy with his hand or putting his arm on the lane rope buoy. Effects of the Invention

[0031] According to the lane rope buoy of the present invention, people in the swimming pool can rest easily by holding it with their hands or putting their arms on it. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 100 Lane Rope Buoy 120 concave support portion 200 cylindrical part R Rope. DETAILED DESCRIPTION

[0034] Hereinafter, embodiments of the present invention will be described using drawings.

[0035] <Implementation Method 1> first, Figures 1 to 3 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 side view of the lane rope buoy 100, Figure 2 (b) is a front view of the swimming lane rope buoy 100, Figure 3 (a) is Figure 2 (a) AA section view, Figure 3 (b) is Figure 3 An enlarged cross-sectional view of the periphery of the end portion of (a).

[0036] The lane rope buoy 100 is a hollow cylindrical body, which has a cylindrical portion 200 in the center through which the rope R can be inserted, and is surrounded by an outer wall 101. Since the interior of the lane rope buoy 100 is hollow, the lane rope buoy 100 can float on the water surface. In addition, the lane rope buoy 100 is bilaterally symmetrical, and the center of gravity is located at the center of the lane rope buoy 100. In addition, the lane rope buoy 100 is blow-molded using a synthetic resin material. As the synthetic resin material constituting the lane rope buoy 100, EVA resin (Ethylen Vinyl Acetate), polyethylene, LDPE (Low-Density Polyethylene), L-LDPE (Linear Low-Density Polyethylene), metallocene polyethylene, polypropylene, elastomer, styrene elastomer or silicon are used, but the present invention is not limited thereto. As long as the lane rope buoy 100 is elastically deformable, any synthetic resin material can be appropriately used. In addition, the lane rope buoy 100 is blow-molded using the synthetic resin material, but the present invention is not limited thereto. The lane rope buoy 100 can also be manufactured by injection molding.

[0037] In addition, the lane rope buoy 100 includes an outer maximum diameter portion 110 having a maximum outer diameter L1, and a concave support portion 120 on the central side having an outer diameter L2 smaller than the outer diameter L1 (L1>L2). The concave support portion 120 is concave so that a person in the swimming pool can hold it with his hand or put his arm on it for support. In addition, since the maximum diameter portion 110 having a larger outer diameter than the concave support portion 120 on the central side is provided, when the person in the swimming pool holds the concave support portion 120 with his hand or puts his arm on the concave support portion 120, the hand or arm is not easy to be separated from the concave support portion 120, and the concave support portion 120 can stably support the person in the swimming pool. Furthermore, by making the outer side the maximum diameter portion 110, at least a part of the outer end of the lane rope buoy 100 is exposed to the water surface even when the person holds the lane rope buoy 100 with his hand or hangs his body on it and sinks. In addition, since the inner end 111 of the maximum diameter portion 110, which is the boundary between the concave support portion 120 and the maximum diameter portion 110, has a larger curvature radius than the outer end 112 and is smoother, when the concave support portion 120 is held by hand or the arm is placed on the concave support portion 120, it will not hurt even if the hand or arm touches the inner end 111.

[0038] In addition, in order to facilitate the people in the swimming pool to hold it with their hands or put their arms on it, the lateral width L3 of the concave support part 120 is 100 to 150 mm (millimeters). In addition, in order to facilitate the people in the swimming pool to hold it with their hands or put their arms on it, the outer diameter of the cylindrical concave support part 120, that is, the diameter L2, is 40 to 60 mm (millimeters). In addition, since the surface of the outer wall 101 of the concave support part 120 is concave and convex, the fingers or arms will not slip. Furthermore, since the concave and convex shape of the surface of the outer wall 101 of the concave support part 120 is smooth, it is easy to hold it with your hands and your hands will not hurt. In addition, the strength of the concave support part 120 is improved by the concave and convex shape of the surface, and even if the concave support part 120 is held by hand and crushed, it is easy to return to its original shape.

[0039] In addition, when the hands or feet of the people in the swimming pool hit the lane rope buoy 100, in order to prevent the maximum diameter part 110 or the concave support part 120 of the lane rope buoy 100 from being elastically deformed and injured, the lane rope buoy 100 is made of a soft synthetic resin material. In addition, since the lane rope buoy 100 is blow-molded from a soft synthetic resin material, the lane rope buoy 100 is easily deformed, and the people in the swimming pool are likely to hold the concave support part 120 with their hands or put their arms on the concave support part 120. In addition, the lane rope buoy 100 is blow-molded, and the wall thickness of the lane rope buoy 100 is thicker at the concave support part 120 than at the outside (maximum diameter part 110). Furthermore, since the concave support part 120 is thick-walled, it is not easy to deform. In addition, the lane rope buoy 100 is hollow and sealed inside by blow molding, so it is easy to return to its original shape even if it is deformed.

[0040] In addition, the lane rope buoy 100 is easily elastically deformed, and in order to effectively prevent injuries even if the hands or feet of people in the swimming pool hit the lane rope buoy 100, the hardness of the lane rope buoy 100 measured by a type A durometer is preferably in the range of 10 to 95. In addition, the hardness of the lane rope buoy 100 is obtained by cutting a part of the lane rope buoy 100 after molding as a test piece and measuring the hardness of the test piece using a type A durometer in accordance with JIS K6253-3.

[0041] In addition, the cylindrical portion 200 is located at the center of the lane rope buoy 100, and the ends 210 on both sides are exposed from the front and back of the lane rope buoy 100. The cylindrical portion 200 extends linearly over the ends 210 on both sides so that the rope R can be inserted therethrough. Figure 3As shown in (b), the tubular portion 200 includes a soft layer 220 facing the inside of the rope R, and a hard layer 230 covering the outside of the soft layer 220. The soft layer 220 and the hard layer 230 extend over the end portions 210 on both sides. The soft layer 220 is formed in a tubular shape so as to surround the rope R, and is formed of a soft synthetic resin material. As the soft synthetic resin material constituting the soft layer 220, EVA resin (ethylene-ethyl acetate copolymer resin), polyethylene, LDPE (low-density polyethylene), L-LDPE (linear low-density polyethylene), metallocene polyethylene, polypropylene, elastomer, styrene elastomer or silicon are used, but the present invention is not limited thereto, and any synthetic resin material can be used as long as it is softer than the synthetic resin material constituting the hard layer 230. In addition, it is best if the hardness of the soft material of the soft layer 220 measured by a type A hardness meter is in the range of 10 to 95.

[0042] In addition, as the hard synthetic resin material constituting the hard layer 230, HDPE (High density polyethylene) is used, but it is not limited to this. As long as it is harder than the synthetic resin material constituting the soft layer 220, it can be composed of any synthetic resin material. In addition, it is best if the hardness of the hard material of the hard layer 230 measured by a type A durometer is in the range of 10 to 95. In addition, the hardness of the soft layer 220 and the hard layer 230 is obtained by cutting a part of the soft layer 220 or the hard layer 230 after molding as a test piece and measuring the hardness of the test piece using a type A durometer based on JIS K6253-3.

[0043] <Implementation Method 2> Then, in Figures 4 to 6 100A of swimming lane rope buoys according to Embodiment 2 of the present invention is shown. Figure 4 This is a perspective view of the entirety of the swimming lane rope buoy 100A. Figure 5 (a) is a side view of the lane rope buoy 100A. Figure 5 (b) is a front view of the swimming lane rope buoy 100A. Figure 6 (a) is Figure 5 (a) BB cross-sectional view, Figure 6 (b) is Figure 6 (a) is an enlarged cross-sectional view of the periphery of the end portion. Figures 1 to 4 The swimming lane rope buoy 100 of the illustrated first embodiment is different only in the configuration of the concave support portion 120A, and the other configurations are the same as the swimming lane rope buoy 100 of the first embodiment, and thus detailed descriptions thereof are omitted.

[0044] The lane rope buoy 100A includes a maximum diameter portion 110A having an outer side with a maximum outer diameter L1, and a concave support portion 120A having an outer diameter L4 smaller than the outer diameter L1 (L1>L4). The concave support portion 120A is concave in shape so that a person in the swimming pool can hold it with their hands or put their arms on it for support. In addition, since the cross-section of the concave support portion 120A is a smoothly curved shape with a depression in the center, it is easy for a person in the swimming pool to hold the concave support portion 120A with their hands or put their arms on the concave support portion 120A. In addition, the lane rope buoy 100A is symmetrical in shape with the center of gravity located at the center of the lane rope buoy 100A. In addition, the diameter of the concave support portion 120A is relatively large. Figure 1 The concave support portion 120 shown is thick, and it is easier to put the arm around it than to hold it with the hand. Moreover, the concave support portion 120A can not only be used to put the arm around it, but also can be used as a pillow to put the neck or head around it.

[0045] In addition, in order to facilitate the people in the swimming pool to hold or put their arms on the concave support part 120A, the lateral width L5 is 100 to 150 mm. In addition, in order to facilitate the people in the swimming pool to hold or put their arms on the concave support part 120A, the outer diameter of the smallest diameter part of the substantially cylindrical concave support part 120A, i.e., the diameter L4, is 80 to 100 mm.

[0046] In addition, the lane rope buoy 100A is a hollow cylindrical body similar to the lane rope buoy 100 of the first embodiment, and is provided with a cylindrical portion 200A in the center through which the rope R can be inserted, and is surrounded by an outer wall 101A. The cylindrical portion 200A has the same structure as the cylindrical portion 200 of the lane rope buoy 100 of the first embodiment, and includes a soft layer 220A facing the inside of the rope R, and a hard layer 230A covering the outside of the soft layer 220A.

[0047] Then, in Figure 7 and Figure 8 1 shows a state where the lane rope buoy 100 of the first embodiment and the lane rope buoy 100A of the second embodiment are attached to the rope R. Figure 7 This is a top view of the swimming lane rope buoy 100 of the first embodiment and the swimming lane rope buoy 100A of the second embodiment attached to the rope R. Figure 8 (a) is Figure 7 CC cross-sectional view, Figure 8 (b) is to Figure 8 (a) is an enlarged cross-sectional view of the periphery of the end portion 210 of the lane rope buoy 100.

[0048] like Figure 7As shown in FIG. 1 , lane rope buoys 100 and lane rope buoys 100A are alternately installed on a long rope R extending in the swimming pool in order to divide each lane M of the swimming pool. Specifically, as shown in FIG. Figure 8 As shown, the rope R is inserted through the cylindrical portion 200 of the lane rope buoy 100 and the cylindrical portion 200A of the adjacent lane rope buoy 100A. The end 210 of the adjacent lane rope buoy 100 and the end 210A of the lane rope buoy 100A abut against each other. Moreover, the people in the swimming pool swimming in each lane M can simply take a rest by holding the concave support portion 120 of the lane rope buoy 100 or the concave support portion 120A of the lane rope buoy 100A, or by hanging their arms. In addition, since the outer end (near the maximum diameter portion) side of the adjacent lane rope buoy is made into the same shape, the design gives a simple impression. Furthermore, the concave support portion (120, 120A) supports the hand or arm as a part of the body of the person in the swimming pool, but the invention is not limited thereto. The concave support portion (120, 120A) can also support any part of the body of the person in the swimming pool so that the person in the swimming pool can rest. Furthermore, the rope R is used as an object for installing the lane rope buoy, but the invention is not limited thereto. Any member such as a wire can be used as long as the lane rope buoy can be installed.

[0049] In addition, since the lane rope buoy (100, 100A) is applied with force by holding it with the hand or by the weight of the person in the swimming pool when hanging it with the arm, the rope R is strongly abutted against the soft layer (220, 220A) of the cylindrical portion 200 in a manner of being sunk. Since the soft layer (220, 220A) is made of a soft material, the friction between the rope R and the soft layer (220, 220A) is increased, so that the rope R can be prevented from rotating relative to the soft layer (220, 220A), and the lane rope buoy (100, 100A) can be suppressed from rotating around the rope R. In addition, the lane rope buoy (100, 100A) can be suppressed from shifting laterally in the length direction of the rope R. As a result, the person in the swimming pool swimming in each lane M can hold the lane rope buoy (100, 100A) in a stable posture to rest.

[0050] In addition, a hard layer (230, 230A) is arranged outside the soft layer (220, 220A). Therefore, when a force is applied to the lane rope buoy (100, 100A), the hard layer (230, 230A) on the outside can suppress excessive deformation of the soft layer (220, 220A) on the inside. As a result, since the soft layer (220, 220A) and the rope R are firmly and strongly abutted, the rotation of the lane rope buoy (100, 100A) can be further effectively suppressed.

[0051] In addition, when the person in the swimming pool does not apply force to the lane rope buoy 100, the rope R and the soft layer (220, 220A) are in contact, but the friction between the two is not strong, so the rope R can rotate relative to the soft layer (220, 220A), and the lane rope buoy (100, 100A) can rotate around the rope R. Figure 7 and Figure 8 In the figure, the lane rope buoy 100 and the lane rope buoy 100A are alternately installed on the rope R, but it is not limited to this. The lane rope buoy 100 and the lane rope buoy 100A can be installed on the rope R in any manner, for example, only one of the lane rope buoy 100 or the lane rope buoy 100A is installed on the rope R, etc.

[0052] In addition, the cylindrical portion (200, 200A) of the lane rope buoy (100, 100A) includes a soft layer (220, 220A) and a hard layer (230, 230A), but the present invention is not limited thereto. The cylindrical portion (200, 200A) may not include the hard layer (230, 230A), and the cylindrical portion (200, 200A) may include only the soft layer (220, 220A), that is, the entire cylindrical portion (200, 200A) may be made of a soft material. Even in this case, since the friction between the rope R and the inner surface of the cylindrical portion (200, 200A) increases, the rope R can be prevented from rotating relative to the soft layer (220, 220A), and the lane rope buoy (100, 100A) can be suppressed from rotating around the rope R. For example, when the entire cylindrical portion (200, 200A) is blow-molded from LDPE (low-density polyethylene) which is a soft material, the resistance with the film wrapped around the surface of the rope R is increased compared to HDPE (high-density polyethylene), so that the lane rope buoy (100, 100A) can be prevented from being laterally displaced in the length direction of the rope R or rotating around the rope R. In addition, by providing the inner surface of the cylindrical portion (200, 200A) with unevenness, when the weight of a person in the swimming pool is applied to the lane rope buoy (100, 100A), the resistance between the cylindrical portion (200, 200A) and the rope R (or a wire, etc.) is increased, so that the lane rope buoy (100, 100A) can be prevented from being laterally displaced in the length direction of the rope R or rotating around the rope R.

[0053] <Implementation Method 3> Then, in Figures 9 to 11 1 shows a swimming lane rope buoy 100B according to a third embodiment of the present invention. Fig. 9 This is a perspective view of the entirety of the swimming lane rope buoy 100B. Fig.10 This is a side view of a lane rope buoy 100B. Fig.11 (a) is Fig.10 DD cross-sectional view, Fig.11 (b) is Fig.11 The enlarged cross-sectional view of the end portion of (a). Figures 1 to 4 The swimming lane rope buoy 100 of the first embodiment shown is different in that it does not include a soft layer and includes a rotation suppressing member 300B, but the other configurations are the same as the swimming lane rope buoy 100 of the first embodiment, and thus detailed descriptions thereof are omitted.

[0054] The structure of the lane rope buoy 100B is the same as that of the first embodiment, but the cylindrical portion 200B of the lane rope buoy 100B does not have a soft layer. In addition, the cylindrical portion 200B is composed of a hard layer 230B extending linearly over the ends 210B on both sides, and the hard layer 230B allows the rope R to be inserted. In addition, rotation suppression members 300B are installed at the ends 210B on both sides of the cylindrical portion 200B.

[0055] The rotation restraining member 300B is made of a synthetic resin material ( Fig.11 In the embodiment, the hard material constituting the hard layer 230B) is made of a softer synthetic resin material, such as Fig.11 As shown in (b), the rotation suppression member 300B includes a cylindrical insertion portion 310B and an end portion 320B. The cylindrical insertion portion 310B is configured to be cylindrical so that the rope R can be inserted therein, and can be inserted into the inner side of the hard layer 230B of the cylindrical portion 200B and installed. Furthermore, if the cylindrical insertion portion 310B of the rotation suppression member 300B is inserted from the end portion 210B side of the cylindrical portion 200B to the inner side of the hard layer 230B, the end portion 320B of the rotation suppression member 300B abuts against the end portion 210B of the cylindrical portion 200B, and thus the rotation suppression member 300B cannot be inserted into the cylindrical portion 200B.

[0056] As the soft material constituting the rotation inhibiting member 300B, EVA resin (ethylene-ethyl acetate copolymer resin), polyethylene, LDPE (low-density polyethylene), L-LDPE (linear low-density polyethylene), metallocene polyethylene, polypropylene, elastomer, styrene elastomer or silicon, etc. are used, but it is not limited to this. As long as it is softer than the synthetic resin material constituting the cylindrical portion 200B, it can be composed of any synthetic resin material. In addition, it is best if the hardness of the rotation inhibiting member 300B measured by a type A hardness meter is in the range of 10 to 95.

[0057] When the lane rope buoy 100B is attached to the rope R, the rope R is inserted through the cylindrical insertion portion 310B and the cylindrical portion 200B of the rotation suppression member 300B. When the person in the swimming pool grabs the lane rope buoy 100B to rest, the force applied to the lane rope buoy 100B by the force of holding it with the hand or the weight of the person in the swimming pool when hanging the arm, the rope R strongly abuts against the cylindrical insertion portion 310B of the rotation suppression member 300B in a manner of being sunk into. Since the cylindrical insertion portion 310B of the rotation suppression member 300B is made of a soft material, the friction between the rope R and the rotation suppression member 300B becomes large, so that the rope R can be prevented from rotating relative to the rotation suppression member 300B, and the lane rope buoy 100B can be suppressed from rotating around the rope R. As a result, the person in the swimming pool can grab the lane rope buoy 100B in a stable posture to rest. Furthermore, since the contact surface with the rope R is worn, maintenance may be required. However, since it is only necessary to replace the rotation restraining member 300B which is a separate body from the cylindrical portion 200B, maintenance is easy.

[0058] The friction between the cylindrical portion 200B and the cylindrical insertion portion 310B of the rotation inhibiting member 300B is stronger than the friction between the rope R and the cylindrical insertion portion 310B of the rotation inhibiting member 300B. Therefore, when a force is applied to the lane rope buoy 100B, the lane rope buoy 100B can be prevented from rotating around the rotation inhibiting member 300B.

[0059] Furthermore, since the rope to which the lane rope buoy of the present invention is attached is arranged so that when the lane rope buoy is subjected to an abnormal load, the hook attached to the outer wall of the swimming pool is removed from the wall before the wire (rope) is broken, the wire (rope) can be prevented from being broken.

[0060] <Implementation Method 4> Then, in Figure 12 to Figure 14 2 shows a swimming lane rope buoy 100 according to a fourth embodiment of the present invention. Fig.12 This is an overall stereogram of a swimming lane rope buoy 100. Fig.13 (a) is a side view of the lane rope buoy 100, Fig.13 (b) is a three-dimensional view showing only the cylindrical portion 200. Fig.14 (a) is a front view of the swimming lane rope buoy 100, Fig.14 (b) is an enlarged front view of the periphery of the cylindrical portion 200.

[0061] The lane rope buoy 100 is a hollow cylindrical body, and has a cylindrical portion 200 in the center through which a rope R can be inserted, and is surrounded by an outer wall 101. Since the interior of the lane rope buoy 100 is hollow, the lane rope buoy 100 can float on the water surface. In addition, the lane rope buoy 100 has a large diameter portion 110 on the outside with the largest outer diameter, and a concave support portion 120 on the central side with an outer diameter smaller than the large diameter portion 110. The concave support portion 120 is concave so that a person in the swimming pool can hold it with his hand or put his arm on it for support. In addition, since the large diameter portion 110 having an outer diameter larger than the concave support portion 120 on the central side is provided, when a person in the swimming pool holds the concave support portion 120 with his hand or puts his arm on the concave support portion 120, the hand or arm is not easy to be separated from the concave support portion 120, and the concave support portion 120 can stably support the person in the swimming pool. In addition, the lane rope buoy 100 has a concave support portion 120, but is not limited to this. As long as a person in the swimming pool can hold the lane rope buoy with his hands or put his arms on the lane rope buoy, it can also be a cylindrical shape without the concave support portion 120, or any other shape.

[0062] The cylindrical portion 200 is located at the center of the lane rope buoy 100, and the ends 210 on both sides are exposed from the front and back of the lane rope buoy 100. The cylindrical portion 200 has an insertion portion 220 surrounded by an outer end portion 280 on the outside, and the insertion portion 220 extends linearly over the ends 210 on both sides so that the rope R can be inserted therethrough. Fig.13 (b) and Fig.14 As shown in FIG. 1 , a stopper wall 231 is provided on the inner side of the cylindrical portion 200, which protrudes further inward than the inner surface 221 of the insertion portion 220. Furthermore, the concave portion surrounded by the stopper walls 231 and the inner surface 221 on both sides constitutes the stopper portion 230. The stopper portion 230 extends linearly over the end portions 210 on both sides. Fig.14 As shown in (b), the inner surface 221 of the insertion portion 220 is continuous in the circumferential direction, but the recessed portion X and the convex portion Y are continuously arranged on the inner surface 221 by the locking wall 231 of the locking portion 230. Therefore, the locking portion 230 forms a concave-convex shape in the circumferential direction of the cylindrical portion 200.

[0063] In addition, the locking wall 231 of the locking portion 230 is an inclined wall that is inclined toward the inner side of the insertion portion 220 as it deviates from the center O of the insertion portion 220 toward the outer end 280. In other words, the outer end 232 side of the locking wall 231 is inclined toward the inner side in a manner close to the center O. Therefore, as shown in the front view of the cylindrical portion 200 Fig.14As shown in (b), when the center of the locking portion 230 is arranged to coincide with the straight line P passing through the center O, the locking wall 231 is inclined in a direction intersecting the straight line P. In addition, the locking wall 231 is an inclined wall inclined inward, but is not limited to this, and can be inclined in any direction. For example, the locking wall 231 can also be formed in a manner parallel to the straight line P. In addition, as Fig.13 As shown in (b) of FIG. 1 , the tubular portion 200 includes a flat portion 201 having no irregularities and a convex protrusion 202 , but the flat portion 201 and the protrusion 202 may be provided in any number.

[0064] In addition, the lane rope buoy 100 is blow-molded using a synthetic resin material. In order to effectively prevent injuries even if the hands or feet of people in the swimming pool hit the lane rope buoy 100, the lane rope buoy 100 uses EVA resin (ethylene-vinyl acetate copolymer resin), polyethylene, LDPE (low-density polyethylene), L-LDPE (linear low-density polyethylene), metallocene polyethylene, polypropylene, elastomer, styrene elastomer or silicon as a synthetic resin material that is easily elastically deformed, but it is not limited to this. As long as the lane rope buoy 100 is elastically deformable, any synthetic resin material can be appropriately used.

[0065] Furthermore, since the cylindrical portion 200 is integrally formed with the entire lane rope buoy 100, the cylindrical portion 200 is also blow-molded using a synthetic resin material. Therefore, the cylindrical portion 200 is formed in a manner of expanding from the center O toward the outer end portion 280 outside, so that the wall thickness of a portion of the cylindrical portion 200 (such as the stopper wall 231, etc.) is thinner on the outer end portion 280 side (such as the outer end 232 of the stopper wall 231) than the wall thickness on the center O side (such as the inner end 233 of the stopper wall 231).

[0066] In addition, the cylindrical portion 200 is integrally blow-molded with the lane rope buoy 100, but the present invention is not limited thereto. The cylindrical portion 200 may be blow-molded separately from the lane rope buoy 100, and then the cylindrical portion 200 and the lane rope buoy 100 are welded to form an integral body. Furthermore, the lane rope buoy 100 and the cylindrical portion 200 are blow-molded, but the present invention is not limited thereto, and they may be manufactured by injection molding.

[0067] Then, in Fig.15 , the swimming lane rope buoy 100 is mounted on the rope R. Fig.15 (a) is a front view of the swimming lane rope buoy 100 in a state where the swimming lane rope buoy 100 is attached to the rope R. Fig.15 (b) is an enlarged front view of the periphery of the cylindrical portion 200.

[0068] like Fig.15As shown, a long strip rope R extending in the swimming pool is inserted into the insertion portion 220 of the cylindrical portion 200 of the lane rope buoy 100 in a manner to divide the swimming lanes of the swimming pool. Generally speaking, the rope R is located at the center O of the cylindrical portion 200, so the lane rope buoy 100 can rotate around the rope R. Moreover, the energy of the waves generated by the people in the swimming pool of each lane is absorbed by the lane rope buoy 100 while rotating, and is effectively consumed and dissipated. In addition, a plurality of lane rope buoys 100 are continuously installed on the rope R, but it is not limited to this, and other components (such as a separate body of the cylindrical portion 200, or a lane rope buoy with an end member 900E described below, etc.) can also be installed at a predetermined interval between the lane rope buoys 100.

[0069] Furthermore, when a person in a swimming pool holds the lane rope buoy 100 with his hand or puts his arm on the lane rope buoy 100 while standing, resting, or nearly drowning in the swimming pool, a force F is applied downward (or toward the center O) to the lane rope buoy 100, and the lane rope buoy 100 is pushed downward (or toward the center O). In this way, the cylindrical portion 200 of the lane rope buoy 100 moves downward toward the rope R located at the center O. Since the locking portion 230 is arranged on the inner side of the cylindrical portion 200, the rope R is locked to the locking portion 230. Furthermore, by applying the force F from the oblique direction, the lane rope buoy 100 rotates along the circumferential direction of the cylindrical portion 200, and the rope R moves in a rolling manner on the inner surface 221 of the insertion portion 220 of the cylindrical portion 200. However, since the locking portion 230 forms a concave-convex shape along the circumferential direction on the inner surface of the cylindrical portion 200, the rope R is prevented from rolling on the inner surface 221 of the insertion portion 220, thereby effectively preventing the lane rope buoy 100 from rotating.

[0070] Furthermore, the locking wall 231 of the locking portion 230 is an inclined wall that is inclined inward as it moves away from the center O of the cylindrical portion 200. Therefore, when the lane rope buoy 100 is elastically deformed to collapse downward (or toward the center O) due to the force F, the locking wall 231 of the locking portion 230 is elastically deformed inward, thereby increasing the contact area with the rope R. As a result, the rope R is strongly locked by the locking portion 230, and the lane rope buoy 100 can be effectively prevented from rotating.

[0071] Furthermore, when the lane rope buoy 100 is elastically deformed in a manner of collapsing downward (or toward the center O) due to the force F, the wall thickness of a portion of the cylindrical portion 200 is thinner on the outer end portion 280 side than on the center O side, so that the outer end portion 280 side is more easily elastically deformed. Furthermore, when a person in the swimming pool holds the lane rope buoy 100 with his hand or puts his arm on the lane rope buoy 100, the cylindrical portion 200 of the lane rope buoy 100 moves downward toward the rope R located at the center O, but since the outer end portion 280 side can be flexibly elastically deformed, the rope R and the stopper 230 on the outer end portion 280 side become easily stuck, and the stopper 230 and the rope R are more closely contacted. Therefore, the rope R is strongly stuck by the stopper 230, and the lane rope buoy 100 can be effectively prevented from rotating.

[0072] In addition, if Fig.15 As shown in (b), the retaining walls 231 on both sides of the retaining portion 230 are constructed in a manner that can contact both sides of the rope R at the same time. For example, the interval between the retaining walls 231 on both sides is equal to or narrower than the width of the rope R. Therefore, the rope R is pressed into the retaining portion 230 and is strongly retained, which can effectively prevent the lane rope buoy 100 from rotating. In addition, the retaining walls 231 on both sides of the retaining portion 230 are constructed in a manner that can contact both sides of the rope R at the same time, but are not limited to this. The interval between the retaining walls 231 on both sides can also be larger than the width of the rope R, so that the retaining walls 231 on both sides of the retaining portion 230 cannot contact both sides of the rope R at the same time. As long as the rope R is retained by one of the retaining walls 231 in the retaining portion 230, the lane rope buoy 100 can be prevented from rotating.

[0073] In addition, a total of four stoppers 230 are arranged on the cylindrical portion 200, and the stoppers 230 are arranged at equal intervals. By arranging four stoppers 230, the rope R can be easily stopped at any stopper 230, so that the rotation of the lane rope buoy 100 can be more effectively prevented. In addition, by arranging four stoppers 230 on the insertion portion 220 of the cylindrical portion 200, Fig.15 In the front view of (b) (i.e., from the viewpoint along the long axial direction of the rope R), the insertion portion 220 is substantially in the shape of a cross. That is, the insertion portion 220 is not in a perfect circular shape, and a portion of the insertion portion 220 has a concave shape that can stop the rope R. In addition, as long as the insertion portion 220 is not in a perfect circular shape and a portion of the insertion portion 220 has a concave shape that can stop the rope R, only one stop portion 230 may be arranged on the cylindrical portion 200, or any number of stop portions 230 may be arranged, which may be more than two.

[0074] <Implementation method 5> Next, refer to Fig.16 , a swimming lane rope buoy 100A according to a fifth embodiment of the present invention will be described. Fig.16The swimming lane rope buoy 100A is an enlarged front view of the cylindrical portion 200A and the surrounding area thereof. The swimming lane rope buoy 100A of the fifth embodiment of the present invention is different in that the cylindrical portion 200A has a locking portion 237A, but is the same as the swimming lane rope buoy 100 of the fourth embodiment in other respects, and therefore detailed description thereof will be omitted.

[0075] like Fig.16 As shown, in the stopper 230A of the tubular portion 200A disposed in the swimming lane rope buoy 100A, a locking portion 237A is formed on the stopper wall 231A. The locking portion 237A is in a shape protruding inward from the stopper wall 231A. Moreover, the locking portion 237A abuts against the outer surface of the rope R engaged with the stopper 230A, and can prevent the rope R from falling off from the stopper 230A to the center O side of the tubular portion 200A. Therefore, the state in which the rope R is engaged with the stopper 230A is maintained more strongly, and the swimming lane rope buoy 100A can be more effectively prevented from rotating. In addition, the locking portion 237A is set at the stopper walls 231A on both sides, but is not limited thereto, and can also be set only at the stopper wall 231A on one side.

[0076] <Implementation Method 6> Next, refer to Fig.17 , a swimming lane rope buoy 100B according to a sixth embodiment of the present invention will be described. Fig.17 This is an enlarged front view of the periphery of the tubular portion 200B of the lane rope buoy 100B. In addition, the configuration of the lane rope buoy 100B of the sixth embodiment of the present invention is different from the configuration of the locking portion 230B of the tubular portion 200B, but the configuration of the lane rope buoy 100 of the fourth embodiment is the same as that of the lane rope buoy 100, so a detailed description is omitted.

[0077] like Fig.17 As shown, a stopper 230B is disposed on the inner side of the cylindrical portion 200B and is formed into a concave shape by being clamped by the stopper walls 231B on both sides. Moreover, since the concave portion XB of the concave part of the stopper 230B and the convex portion YB of the stopper wall 231B are continuously disposed, the stopper 230B forms a concave-convex shape in the circumferential direction of the cylindrical portion 200B. Therefore, the rope R is stopped by the stopper 230B, which can effectively prevent the lane rope buoy 100B from rotating. In addition, the insertion portion 220B of the cylindrical portion 200B is provided with two opposing stopper portions 230B. Fig.17 In the front view (ie, from the viewpoint of the long axial direction of the rope R), the insertion portion 220B is substantially elliptical. Thus, the insertion portion 220B is not a perfect circle, and a portion of the insertion portion 220B has a concave shape that can lock the rope R.

[0078] <Implementation Method 7> Next, refer to Fig.18 , a swimming lane rope buoy 100C according to a seventh embodiment of the present invention will be described. Fig.18 The buoy 100C for swimming lane ropes is an enlarged front view of the periphery of the cylindrical portion 200C of the swimming lane rope buoy 100C. In addition, the structure of the swimming lane rope buoy 100C of the embodiment 7 of the present invention is different from the structure of the locking portion 230C of the cylindrical portion 200C, but the other aspects are the same as the structure of the swimming lane rope buoy 100 of the embodiment 4, so the detailed description is omitted.

[0079] like Fig.18 As shown, on the inner side of the cylindrical portion 200C, there is a stopper 230C which is clamped by the stopper walls 231C on both sides and is formed into a concave shape. Moreover, since the concave portion XC of the concave part of the stopper 230C and the convex portion YC of the stopper wall 231C are continuously arranged, the stopper 230C forms a concave and convex shape in the circumferential direction of the cylindrical portion 200C. Therefore, the rope R is stopped by the stopper 230C, which can effectively prevent the lane rope buoy 100C from rotating. In addition, the insertion portion 220C of the cylindrical portion 200C is provided with three stopper portions 230C. Fig.18 The insertion portion 220C is substantially triangular in shape when viewed from the front (ie, from the viewpoint in the longitudinal direction of the rope R). Thus, the insertion portion 220C is not a perfect circle, and a portion of the insertion portion 220C has a concave shape that can lock the rope R.

[0080] In addition, the insertion portion 220C may include four or more locking portions 230C. In this case, Fig.18 In the front view (i.e., from the viewpoint of the long axial direction of the rope R), the insertion portion 220C is a polygonal shape such as a substantially quadrilateral shape. Fig.18 In the front view (i.e., from the viewpoint in the long axial direction of the rope R), even if the cylindrical portion 200C or the insertion portion 220C is substantially triangular, elliptical, or polygonal, the locking portion 230C also forms a concave-convex shape in the circumferential direction.

[0081] <Implementation Method 8> Next, refer to Fig.19 , a swimming lane rope buoy 100D according to an eighth embodiment of the present invention will be described. Fig.19 (a) is a perspective view showing only the cylindrical portion 200D of the swimming lane rope buoy 100D. Fig.19 (b) is an enlarged front view of the periphery of the tubular portion 200D of the lane rope buoy 100D. In addition, the configuration of the lane rope buoy 100D of the eighth embodiment of the present invention is different from the configuration of the stopper 230D of the tubular portion 200D, but the configuration of the lane rope buoy 100 of the fourth embodiment is the same as that of the lane rope buoy 100, so the detailed description is omitted.

[0082] like Fig.19 As shown in FIG. 2 , a plurality of convex stop walls 231D are partially provided on the inner side of the cylindrical portion 200D. Specifically, as shown in FIG. Fig.19 As shown in (a), a plurality of first stop walls 231D1 are arranged spaced apart from each other. Moreover, each stop wall 231D1 is arranged in the same straight line along the length direction of the cylindrical portion 200D, so that Fig.19 As shown in (b), each stop wall 231D1 overlaps front and back. Fig.19 As shown in (a), the second stopper walls 231D2 are arranged in a plurality of spaces from each other. Moreover, each stopper wall 231D2 is arranged in the same straight line along the length direction of the cylindrical portion 200D, so that Fig.19 As shown in (b), each stop wall 231D2 overlaps front and back. Fig.19 As shown in (a), a plurality of third stop walls 231D3 are arranged spaced apart from each other. Moreover, each stop wall 231D3 is arranged in the same straight line along the length direction of the cylindrical portion 200D, so that Fig.19 As shown in (b), the locking walls 231D3 overlap front and back.

[0083] Moreover, if Fig.19 As shown in (b), the portion that is concave and is sandwiched by the adjacent stop walls 231D becomes the stop portion 230D. When viewed from the front of the cylindrical portion 200D, the concave portion XD of the concave portion of the stop portion 230D and the convex portion YD of each stop wall 231D are continuously arranged, so that the stop portion 230D forms a concave-convex shape in the circumferential direction of the cylindrical portion 200D. Therefore, the rope R is stopped at the stop portion 230D, and the lane rope buoy 100D can be effectively prevented from rotating.

[0084] <Implementation Method 9> Next, refer to Fig. 20 A swimming lane rope buoy 100E according to a ninth embodiment of the present invention will be described. Fig. 20 (a) is an enlarged perspective view of the periphery of the end 210E of the cylindrical portion 200E of the swimming lane rope buoy 100E. Fig. 20 (b) is an enlarged front view of the periphery of the cylindrical portion 200E of the lane rope buoy 100E. In addition, the configuration of the lane rope buoy 100E of the ninth embodiment of the present invention is different in that the cylindrical portion 200E does not have a stopper but has an end member 900E, but the configuration of the lane rope buoy 100 of the fourth embodiment is the same as that of the lane rope buoy 100, and therefore a detailed description thereof is omitted.

[0085] like Fig. 20As shown in (a), the cylindrical portion 200E does not have a stopper, but is configured to be able to mount an end member 900E having a stopper 930E. Specifically, the end member 900E has an insertion portion 920E surrounded by an outer edge portion 980E on the outside, and the insertion portion 920E extends linearly over the end portions 910E on both sides in a manner that allows the rope R to be inserted. Moreover, the end member 900E is inserted from the end portion 210E of the cylindrical portion 200E and mounted inside the cylindrical portion 200E. In addition, the end member 900E is blow molded or injection molded using a synthetic resin material.

[0086] In addition, if Fig. 20 As shown in (b), a stopper wall 931E protruding inward is provided on the inner side of the end member 900E. The concave portion sandwiched by the stopper walls 931E on both sides becomes the stopper portion 930E. When the end member 900E is mounted on the cylindrical portion 200E, the stopper portion 930E is disposed on the inner side of the cylindrical portion 200E. Fig. 20 As shown in (b), in the front view of the cylindrical part 200E, since the concave part XE of the concave portion of the locking part 930E and the convex part YE of the locking wall 931E are continuously arranged, the locking part 930E forms a concave-convex shape in the circumferential direction of the cylindrical part 200E. Therefore, the rope R is locked to the locking part 930E, and the swimming lane rope buoy 100E can be effectively prevented from rotating.

[0087] In addition, the lane rope buoy of the present invention is not limited to the above-mentioned embodiments, and various modifications and combinations are possible within the scope described in the scope of the patent application and the scope of the embodiment, and such modifications and combinations are also included in the scope of the rights.
