Abstract
A lane rope float having higher wave absorbing performance than before is provided. A lane rope float is one that is attached to a rope R via a tubular portion and divides lanes of a pool, and the lane rope float is characterized by: including a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope R, and a wall surface portion that is coupled to side end portions of the blades to cover the blades, in which in an outer end portion of the lane rope float from the center of the tubular portion to the wall surface portion, at least ½ of the range from the center of the tubular portion to the wall surface portion is formed along a vertical plane V2 perpendicular to the tubular portion.
Claims4
A lane rope float that is attached to a rope via a tubular portion and divides lanes of a pool, the lane rope float comprising:
- a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope;
- and
- a wall surface portion that is coupled to side end portions of the blades to cover the blades, wherein
- an opening formed obliquely is formed on the wall surface portion.
A lane rope float that is attached to a rope via a tubular portion and divides lanes of a pool, the lane rope float comprising:
- a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope;
- and
- a wall surface portion that is coupled to side end portions of the blades to cover the blades, wherein
- protruding plates are formed on the blades in parallel with the rope so as to protrude from the inner surface of the blades.
A lane rope float that is attached to a rope via a tubular portion and divides lanes of a pool, the lane rope float comprising:
- a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope;
- and
- a wall surface portion that is coupled to side end portions of the blades to cover the blades, wherein
- the lane rope float being configured such that when a plurality of the lane rope floats is continuously attached to the rope, a void ratio among the lane rope floats within a range of 1 m in side view is 5% or less.
A lane rope float that is attached to a rope via a tubular portion and divides lanes of a pool, the lane rope float comprising:
- a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope;
- and
- a wall surface portion that is coupled to side end portions of the blades to cover the blades, wherein
- the lane rope float being configured to have a specific gravity of 0.4 to 0.6 such that when the lane rope float is attached to a rope installed in a pool, a portion of the lane rope float, above the tubular portion, is located above a water surface of the pool.
