Conventionally, the line L is generally formed by drawing a line L on the floor surface of the pool P with a water-resistant white paint, or by embedding a white tile in series.

By the way, the competition pool P generally has a 50m × 25m pool based on international rules and a 25m pool based on domestic rules.
There is a pool.

When this 50m × 25m pool is used, for example, as a pool for domestic rules, the 50m pool is to be provided along a course line L along a width direction b orthogonal to the pool longitudinal direction a.
Must be set again, the conventional course line L drawn directly on the floor of the pool must be erased, and a new 25 m course line L must be redrawn. There was a problem that work was actually impossible. Such a problem similarly occurs regardless of whether the floor of the pool P is of a fixed type or of an ascending and descending type.

The present invention has been made in view of the above situation, and has as its object the pool floor is formed so as to be able to ascend and descend, and when setting a course line on this pool floor, a course is required. It is an object of the present invention to provide a course line device such as a pool in which the course line can be set extremely easily regardless of the direction of the line.

[Means for solving the problem]

In order to achieve the above object, according to the present invention, a plurality of line boards are removably mounted on the upper surface of a pool floor configured to be able to move up and down along a pool wall surface, and a plurality of line boards are interconnected. It is premised on a course line device such as a pool that sets a straight course line, and each of these line plates is interposed between a stopper penetrating the pool floor surface and the stopper and the line plate. A washer is attached to the upper surface of the pool floor via a washer.

[Action]

Therefore, in the course line device such as a pool according to the present invention, first, a required number of line plates are linearly arranged in a certain direction and connected, and each of the connected line plates is connected to the fastener and the washer. A course line can be set in an arbitrary direction by attaching or detaching the pool line to or from the pool floor through the interface.

〔Example〕

Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings.

As shown in FIG. 1, a course line device such as a pool according to the present invention includes a pool floor 1 configured to be able to move up and down along a pool wall surface (not shown), and an upper surface of the pool floor 1. It is composed of a plurality of line plates 2 arranged and a stopper 3 for attaching the line plates 2 to the upper surface of the floor 1.

Although not shown, the pool to which the present invention is applied is not limited to any type as long as the pool has various known raising and lowering floors whose floors are controlled to be raised and lowered by driving means such as gears and ropes. The present invention can be applied to a pool that adopts.

In the illustrated embodiment, the pool floor 1 is formed by arranging a number of floor materials 10 in parallel on a support frame (not shown).

The flooring 10 is preferably formed of a hollow member in order to make the pool floor 1 lightweight, and it is desirable to seal the air inside.

The line boards 2 are arranged in the same direction as the axial direction (longitudinal direction a in FIG. 9) of the floor material 10 constituting the pool floor surface 1. In this embodiment, a specific floor is used. Lumber 10a
, Each line plate 2 is attached.

That is, as shown in FIGS. 2 and 3, each of the line plates 2 has a relatively narrow and long main body portion 20 formed to have the same width as that of the conventional course line. Main unit 20
, A hook portion 22 bent at one end (right end in the drawing) of the main body portion 20, and the other end (left end in the drawing) of the main body portion 20 Receiving part 23 formed by bending
And is curved in the shape of an inverted dish in the width direction to provide elasticity.

As shown in FIG. 4, the mounting portion 21 is concavely formed in a circular shape in a plane. In the mounting portion 21, the stopper 3 and a washer 4 described later are interposed. 21
A cross-shaped stopper fitting insertion hole 21a is formed.

In the present embodiment, the above-mentioned stopper insertion hole 21a is formed in a cross shape, but it is needless to say that it can be formed in a single character shape or another shape according to the use.

In the above embodiment, the mounting portion 21 of the line plate 2
Although the case where three are formed is illustrated, the present invention is not limited to this, and for example, two or more can be formed.

Note that, of the line plates 2, the line plate 2 disposed at the end of the pool floor surface 1, that is, at a position facing the pool wall surface.
In FIG. 5, the mounting part 21 or the hook part 22 is not formed, but is formed in a straight line so as not to open between the course line and the pool wall surface. As shown, the front shape is substantially I
The upper locking part 30 and the lower locking part 31
And a shaft portion 32 that connects the upper and lower locking portions 30 and 31.

As shown in FIG. 5, both lower ends of the lower locking portion 31 are bent downward to form a guide portion 31a.
By gripping and rotating the guide portion 31a, the locking operability of the stopper 3 is improved.

As shown in FIGS. 6 and 7, the washer 4 is fitted into the mounting portion 21 of each of the line plates 2 and is formed. A one-character-shaped stopper insertion hole 41 is formed in a direction orthogonal to the part 40.

When the course line L is assembled, the upper locking portion 30 of the stopper 3 is fitted and locked in the concave portion 40, and the locking portion 30 and the shaft portion 32 are respectively fitted in the insertion hole 41. It is configured to be locked.

Note that the washer 4 is not necessarily required when the fastener insertion hole 21a of the mounting portion 21 is formed in a single character instead of the cross shape.

A case where the course line device having the above configuration is assembled along the longitudinal direction of the pool (a direction in FIG. 10) will be described with reference to FIGS. 8 and 9.

First, the required number of line boards 2 are arranged linearly along the longitudinal direction of the pool on the upper surface of the floor material 10 (10a in the illustrated example) constituting the pole floor surface 1, and the hook portions 22 of each line board 2 are arranged.
And the receiving part 23 are connected. At this time, as the line plates 2 disposed at both ends of the course line L, those in which the hook portion 22 or the receiving portion 23 is not formed at the end facing the pool wall surface are used.

The washer 4 is fitted into the fitting 21, and the lower fitting portion 31 of the fitting 3 is checked while the fitting fitting hole 41 of the washer 4 and the fitting fitting hole 21 a of the lower mounting portion 21 communicate with each other. Then, the shaft portion 32 is inserted through the fastener insertion hole 21a and the lower locking portion 31 (see FIG. 8).

In this state, since the guide portion 31a of the lower locking portion 31 protrudes from the lower surface of the floor material 10a, if the guide portion 31a is gripped as it is and the stopper 3 is turned, the lower surface of the floor material 10a The locking portion 31 is brought into contact.

On the other hand, the upper locking portion 30 of the stopper 3 is fitted into the recess 40 of the washer 4 by turning the stopper 3, and the line plate 2 is attached to the pool floor 1 by the stopper 3. Ends.

At this time, since the line plates 2 are formed to have elasticity by being curved in the width direction, each line plate 2 is in close contact with the pool floor surface 1 and both ends of the line plate 2 are turned up by water pressure or the like. Never go up.

In the above embodiment, the case where the course line L is assembled along the longitudinal direction of the pool (the direction of FIG. 10a) has been described as an example.
The rearrangement in the direction of FIG. 10b can be easily performed. In this case, the mounting state of the stopper 3 is released, and the respective line plates 2 are rearranged in the direction of FIG. 10b, whereby the following steps can be assembled.

〔The invention's effect〕
