Problems solved by technology

[0003] However, with regard to the lane-marking float disclosed in this patent document 1, since the wing plates and the outer peripheral wall are firmly connected with the central plate, the overall structure becomes difficult to deform, so even the hands or feet of the swimmer It is not easy to bend when the part collides with the float for the lane line, which may cause injury to swimmers
Therefore, the lane-dividing float disclosed in Patent Document 1 does not fully consider how to effectively prevent injuries to swimmers' hands or feet due to collisions.

Embodiment approach 1

[0041] first,figure 1 and figure 2 The float main body 100 for lanes according to Embodiment 1 of this application is shown. figure 1 (a) is an overall perspective view of the float main body 100 for the lane line, figure 1 (b) is a front view of the float main body 100 for the lane line, figure 2 (a) is figure 1 A-A sectional view of (b), figure 2 (b) is a side view of the float main body 100 for lane dividing lines. In addition, the lane-dividing float 300 to be described later is composed of the lane-dividing float main body 100 and the buoy 200 . figure 1 and figure 2 In , the state which removed the buoy 200 from the float main body 100 for lanes is shown. In addition, although the lane-dividing float 300 of the first embodiment is composed of the lane-dividing float main body 100 and the buoy 200, it is not limited thereto, and the lane-dividing float main body 100 is formed by foam molding or blow molding. , or when molding by injecting gas or air, etc., when...

Embodiment approach 2

[0088] Next, in the Figure 5 The float main body 100C for lane lanes of the float for lane lanes which concerns on Embodiment 2 of this invention application is shown in FIG. also, Figure 5 It is a front view of the float main body 100C for lane lanes of the float for lane lanes. In addition, the float for the lane line according to the second embodiment is only compatible with Figure 1 to Figure 4 The lane-marking float 300 according to the first embodiment shown is different from the inner connecting portion 150C in structure, and other structures are the same as the lane-marking float 300 according to the first embodiment, so detailed description thereof will be omitted.

[0089] Such as Figure 5 As shown, the float main body 100C for lanes is provided with an inner connecting portion 150C having a wide portion 151C and a narrow portion 152C narrower than the wide portion 151C inside the outer peripheral wall 130AC. The narrow portion 152C is arranged between the ad...

Embodiment approach 3

[0093] Next, in Figure 6 A float 300D for lanes according to Embodiment 3 of the present application is shown in . also, Figure 6 It is an overall perspective view of the float 300D for the lane dividing line.

[0094] Such as Figure 6 As shown, the lane line float 300D is a hollow cylinder, and has a cylindrical portion 110D through which a rope R can be inserted through the center. Since the inside of the lane-dividing float 300D is hollow, the lane-dividing float 300D can float on the water surface. In addition, the outer peripheral wall 130D of the lane-line float 300D is configured to be elastically deformable inward. In addition, the lane-dividing float 300D is not limited to a cylinder, and may have an arbitrary shape.

[0095] In addition, the lane line float 300D is blow-molded using a synthetic resin material. Furthermore, in the present embodiment, as the synthetic resin material constituting the lane line float 300D, EVA resin (ethylene-vinyl acetate copol...

Abstract

Provided is a lane rope float that does not easily injure a swimmer even should a collision occur with the hands, feet, or the like. The lane rope float (300) is characterized in that each lane in a pool is divided by being mounted to a rope (R) via a cylinder (110) and is formed from a synthetic resin material; the float (300) is provided with, on the periphery of the cylinder (110), a plurality of vanes (120) that protrude parallel to the rope (R), and an outer circumferential wall (130) that covers the vanes (120) and that is connected to side ends (121) of the vanes (120); grooves (160A) are formed between the side ends (121 of the vanes (120) and the outer circumferential wall (130), connection ends (122) of the side ends (121) of the vanes (120) are connected to the outer circumferential wall (130), and the outer circumferential wall (130) can elastically deform toward the vanes (120) so that the grooves (160A) collapse.

Description

technical field [0001] The application of the present invention relates to a float used in lanes of swimming pools and the like. Background technique [0002] In the prior art, various lane-marking floats are known. For example, the lane-marking float disclosed in Patent Document 1 includes: a cylindrical portion through which a rope is inserted through a central portion; a central plate, Extending around the cylindrical portion; a plurality of wings protruding from the central plate parallel to the rope; and an outer peripheral wall connected so as to surround the wings. Then, the waves generated by the swimmers in each lane are introduced into the lane line float, and the waves are dissipated by the wings and the outer peripheral wall. [0003] However, with regard to the lane-marking float disclosed in this patent document 1, since the wing plates and the outer peripheral wall are firmly connected with the central plate, the overall structure becomes difficult to deform,...
