[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a float that is inserted into a course rope of a swimming pool, and is related to improvement of a wave canceling effect.

[0002]

[Prior art]

 A conventional course rope float has a rim formed on the outer edge of the side plate at the end of the hemispherical curved surface with a boss formed in the center, and a plurality of blades are provided on the inner side of the rim and the outer side of the hemispherical curved surface to allow water to flow through the side plate. It is known that a float half body with a hole is assembled by fitting a hollow sphere with a through hole at the center inside the hemispherical curved surface of a pair of half bodies with side plates facing each other. Kaihei 5-200 bulletin).

The float is assembled by forming a water passage hole and a window hole and a small hole located outside the water passage hole in the side plate at the end of the hemispherical curved surface of the float half body, and at the outer end of each blade. A lateral hook protruding from the side plate is formed on the side plate, and the back side projection of the hook piece inserted through a pair of hemispherical window holes with the side plates facing each other turns into a small hole in the other hemisphere when the hemispheres rotate in opposite directions. It is a matter of engagement.

Since such floats cannot be separated unless they are rotated in opposite directions, the normal state of the floats was maintained even when a strong impact was received. In addition, a large number of course ropes are inserted and the buoyancy of the hollow sphere separates the course on the water surface, and the float rotation centered on the course rope can reduce the contact impact of swimmers.

[Problems to be solved by the device]

 However, the above-mentioned conventional float is not always sufficient in terms of the wave-dissipating action of reducing the energy of the wave propagating to the adjacent course. In other words, the vane, which has a surface almost perpendicular to the wave propagation direction, reflects the wave and only absorbs the energy by the rotation of the float. Further, regarding the assembling structure, the assembling by the engagement of the back side protrusion of the hook piece with the small hole has a restriction on the die manufacturing and the forming. The purpose of this invention is to obtain a float having a high wave-dissipating effect and a float having a highly productive assembly structure.

[Means for Solving the Problems]

 This invention has an inner bottomed cylindrical body having a bottom surface and a course rope insertion hole at the center of the bottom surface and accommodating a buoyancy body, an outer cylindrical body concentric with the inner bottomed cylindrical body, and an inner inner cylindrical body. A plurality of blades installed on the radial surface from the concentric cylinder axis extending over the bottom cylinder and the outer cylinder, and one cylinder end of the outer cylinder, the back end of the blade, and the inner bottomed cylinder. A float that is assembled by accommodating the buoyancy body by stacking two float halves, each of which is composed of a side plate having a plurality of water passage holes and connecting the cylindrical ends of the body, and the side plates are stacked together. A pool course characterized by having a plurality of wave-dissipating holes that are vertically long in the direction parallel to the cylinder axis on the cylindrical surface of the body or on the cylindrical surface of the outer cylindrical body and the cylindrical surface of the inner bottomed cylindrical body. It is a rope float. Also, when assembling the float, the horizontal hooks provided on the outside of the rear end of the vane of the float half-body protruding from the side plate are used as the crosspieces that divide the water passage holes in the side plate of the other float. It is a matter of suspension.

[Embodiment]

 The invention will be described with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing the float of the embodiment separated into two float halves and a buoyant body. FIG. 2 is a side view of the float half with the lower half shown in cross section. In the drawing, the center line of the alternate long and short dash line in Fig. 1 is vertically offset at the point X, and the two float halves have exactly the same shape.

In both figures, 2 in the two float halves 1A, 1B are an inner bottomed cylindrical body, 3 are outer cylindrical bodies, 4 are vanes, 5 are side plates, and these are integrally made of thermoplastic resin. It is molded. Further, 6 is a hollow buoyant body that is resin blow molded. A rope insertion hole 22 is provided in the center of the bottom surface 21 of the inner bottomed cylindrical body 2 of the float half body 1B, and a vertically long wave-eliminating hole 23 is provided in the cylindrical surface of the float 1B in a direction parallel to the rope. Has been. The holes provided on the bottom surface 21 are water passage holes. As seen in the float half 1A, the wave-dissipating through holes 23 are provided on the entire circumferential surface of the cylinder, and the buoyant body 6 is housed inside the inner bottomed cylindrical body 2 as shown in the drawing.

As seen in the float half body 1B, the outer cylindrical body 3 is arranged concentrically with the inner bottomed cylindrical body 2, and a wave-eliminating through hole 31 which is vertically long in the direction parallel to the rope is provided on the outer periphery thereof. Many are set up. Eight vanes 4 are arranged between the outside of the inner bottomed cylinder 2 and the inside of the outer cylinder 3 along the radial plane from the axis.

As seen in the float half 1A, the end portion of the inner bottomed cylindrical body 2, the end portion of the outer cylindrical body 3 and the end portion of the vane 4 are connected by the side surface plate 5, and the side surface plate 5 A large number of water passage holes 51 are provided in the. One of the water passage holes 51 is defined by the end portion 41 of the blade 4, and the other one is a crosspiece 52. The end part 41 is provided with a lateral hook piece 42 projecting outward from the side plate, and when it is overlapped with the float half body 1B of the assembly partner, the projecting hook piece 42 will pass the water of the float half body 1B. When the float halves 1A and 1B are rotated into the holes, they are engaged with the crosspieces of the float half 1B.

[Effect of device]

 According to this invention, in addition to the fact that the vanes reflect waves to the adjacent course as in the case of the conventional float, the vanes are either on the cylindrical surface of the outer cylinder or on both cylindrical surfaces of the outer cylinder and the inner bottomed cylinder. In addition, since a large number of vertically long wave-dissipating holes are provided in the direction perpendicular to the wave propagation direction, that is, in the direction parallel to the cylindrical axis, the wave-dissipating effect is significantly improved compared to the conventional float. Also, since the two float halves are assembled by the engagement of the horizontal hook piece and the crosspiece, the degree of freedom of engagement is higher than the engagement with the small hole in the conventional float, and the mold production is successful. Shape productivity has improved.
