Description

[Detailed Description of the Invention] [Industrial field of application] This invention follows an ascending / descending movement of a pool floor through an opening that opens when an arm connecting a vertically movable pool floor and a drive device moves up and down. The present invention relates to a blindfold device in a pool floor elevating device that can be automatically hidden.

[Prior Art] Conventionally, a pool having a pool floor that can be raised and lowered is well known, and most of the pool floors are guided up and down by a drive device using a gear or a chain.

In a pool having such a pool floor, a drive unit, a wheel group, and a chain may be installed underground, and in this case, the pool floor and the drive unit are connected via an arm. The arm is moved up and down along the vertically long slit-shaped openings formed at the four corners of the pool wall.

However, since the pool is often used by children, etc., if the above-mentioned opening is left open,
There is a problem that the above-mentioned children may be injured by putting limbs or the like in the opening, which is dangerous.

As means for solving such a problem, a vertically elongated rubber plate is attached to both sides of the vertically elongated slit-shaped opening to blind the opening, and the above-mentioned configuration is provided along the gap between the facing surfaces of the rubber plate. A means of raising and lowering the arm can be considered.

[Problems of conventional technology]

However, in the above-mentioned conventional solving means, there is a problem that the rubber plate is easily deteriorated by sliding contact with the arm, and the limbs enter through the gap formed between the facing surfaces of the rubber plate. Therefore, there was a problem that it was not a fundamental solution.

The present invention has been made in view of the present situation, and an object thereof is a safe pool floor elevating device capable of automatically closing the opening portion by following up and down movements of the pool floor. In order to provide a blindfold device.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, a blindfold device in a pool floor lifting device guides a narrow and long shutter plate, a drum for winding the shutter plate, and the shutter plate. It consists of a guide roller and
One end of the shutter plate is connected to an arm that connects the pool floor and the drive device, and the shutter plate is configured to conceal the opening portion where the arm moves up and down as the pool floor moves up and down. To do.

[Action]

Therefore, in the blindfold device according to the present invention, when the pool floor moves up and down, the shutter plate, one end of which is connected to the arm, moves up and down following the up and down movement of the arm, and automatically. The opening is hidden.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings.

As shown in FIG. 1, a pool floor lifting / lowering device according to this embodiment includes a pool floor 1 that is vertically movable along a pool wall surface W, and a drive device 2 that lifts / lowers the pool floor 1.
And a blindfold device 3 arranged in the drive mechanism 2.

As shown in FIG. 2, the pool floor 1 includes a support frame 10 formed of a channel material having a substantially U-shaped cross section, and a large number of long floor materials 11 juxtaposed on the support frame 10. It is configured.

The support frame 10 is sufficient if it is formed to have a predetermined strength, but it is preferable to select a material that can reduce the weight as much as possible.

Although not shown, the floor material 11 has a hollow portion, and the hollow portion is sealed so that buoyancy is generated on the floor.

As shown in FIG. 1, the drive device 2 includes a chain 20 connected to a support frame 10 forming the pool floor 1, and the chain 20.
And a drive mechanism 22 for driving a drive wheel 21a in the wheel group 21, and the chain 20 and the wheel group 21 excluding the drive mechanism 22
Is located below the four corners of the pool edge,
The drive mechanism 22 is housed in a drive chamber (not shown) formed below the peripheral edge of the pool.

In addition to the drive wheel 21a, the wheel group 21 is configured to include a pair of sprocket wheels 21b and 21c that are vertically arranged and intermediate tension wheels 21d and 21e.

Therefore, in the drive device 2, the swing of the pool floor 1 when the pool floor 1 is moved up and down can be significantly reduced, and the swing and the vertical movement of the pool floor 1 during use can be effectively controlled. At this time, by arranging the steady rest roller R as shown in FIG. 2 at the peripheral edge of the pool floor 1, it is possible to effectively prevent the pool wall W and the pool floor 1 from being damaged.

The drive mechanism 22 includes a motor 22a as shown in FIG.
A speed reducer 22b, and a drive shaft 22c that transmits the controlled rotation to the drive wheel 21a.

The motor 22a and the speed reducer 22b are connected to the sprocket wheels 22e and 22f via a chain 22d, and the torque limiter 22 is provided between the speed reducer 22b and the drive shaft 22c.
g is provided, and the drive shaft 22c has an encoder 22h.
Is attached.

As shown in FIG. 3, the blindfold device 3 includes the wheel group 21.
A shutter plate having a narrow width and a long length, which is disposed in a frame 23 in which the
30, a drum 31 that winds the shutter plate 30, a guide roller 32 that guides the shutter plate 30, and a face plate 33 that also functions as a decorative plate with which the shutter plate 30 is slidably contacted. There is.

By forming the shutter plate 30 with the spring steel material in this manner, it is possible to prevent the deterioration for a long period of time, as compared with the case where the shutter plate 30 is formed with a rubber plate, for example.

Further, the drum 31 is biased in the direction in which the shutter plate 30 is wound up.

A pair of guide rollers 32 are arranged on the face plate 33 side.

The shutter plate 30 of the blindfold device 3 configured in this way is
One end is connected to the other end of the arm 26 connected to the pool floor 1, and the other end is connected to, for example, a spring (not shown) that biases the shutter plate 30 in the winding direction. As the arm 26 moves up and down together with the pool floor 1, the shutter plate 30 is pulled or pushed back by the arm 26 to automatically hide the gap A between the face plates 33, 33 on which the arm 26 moves up and down. . Of course, in this invention, even if the spring is not connected to the other end of the shutter plate 30,
Since the shutter plate 30 slides as the arm 26 moves up and down, no problem occurs.

Therefore, the gap between the face plates 33, 33 is not exposed to the outside, and safety can be ensured without the concern that children will accidentally put their hands or feet in the gap and be injured.

(Effect of the device) The blindfold device in the pool floor lifting device according to the present invention is
As described above, the opening through which the arm necessary for raising and lowering the pool floor is guided is configured to automatically close following the vertical movement of the pool floor, so children etc. Since no limbs can be put in, safety can be greatly improved.
