Therefore, in the lid device for a pool or the like according to the present invention, during use of the pool or the like, the support pillars are removed from the screw holes, and the lid is lowered on the floor of the pool or the like, and the pool or the like is used. If not, the support columns are screwed into the screw holes of the lid fitted in the opening of the pool or the like, respectively, and the support columns are rotated via the connecting members connected to the pulleys attached to these support columns. By moving the lid, the lid is raised to the upper end of the opening of the pool or the like.

〔Example〕

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

As shown in FIG. 1, in this embodiment pool 1
An opening 1a for storing water or the like is formed in a concave cross section. A lid 10 is fitted in the opening 1a so as to be able to move up and down along the wall surface 1b of the pool 1.

When the pool 1 is used, the lid 10 is located at the bottom of the pool 1.
The pool 1 is lowered to 1a and is used as a floor of the pool 1. At four corners of the pool 1, as shown in FIGS. 2 and 3, support pillars 20 penetrate when the pool is not used. Screw holes 10a are provided. In the figure, reference numeral 11
The cap 11 is detachably screwed into the screw hole 10a.

The lid 10 has a large number of floor members 12 formed of a synthetic resin, an aluminum material or a stainless steel material and formed in a rectangular cylindrical shape, and a support member disposed on the lower surface of the group of the floor members 12.
At 13 they are integrally connected and assembled.

At this time, the number of the floor members 12 that can provide a floor area slightly smaller than the area of the opening 1a is juxtaposed.

The unit for connecting the floor member 12 and the supporting member 13 integrally is connected by known means such as welding or bolts and nuts 14.

Of course, although not shown, the floor material 12 can be closed at both ends with an appropriate cap body, and when the lid body 10 is raised and lowered, air is sealed inside each floor material 12 so that the lid body 10 in water can be closed. By configuring so that the weight cancels out with the buoyancy to become substantially “zero”, it is also possible to configure so that the labor required for raising and lowering the lid 10 can be further reduced.

The support column 20 is screwed onto the lid 10, and is configured so that the lid 10 can be moved up and down by rotating the lid.

That is, as shown in FIG. 4, the support column 20 is formed by connecting a plurality of (two in this embodiment) separable support tubes 21 and 22.

Also, screw threads 21 engraved on the outer periphery of the support tubes 21 and 22 are provided.
In this embodiment, a and 22a are described as taking square screws as an example in consideration of the convenience of transportation of the support tubes 21 and 22. However, it is a matter of course that a mountain screw may be used instead. is there.

By forming the support column 20 in the form of a tubular body in this way, it is advantageous because it has a greater stress against bending than a simple rod-shaped body, and by being freely connectable, it is easier to transport and handle it. It is convenient.

On the other hand, a sliding member 23 is detachably attached to the lower end of the support tube 21 on the lower end side.

The sliding member 23 has a spherical lower end, and is fitted with the concave spherical portion of the seat 2 attached to the bottom 1c of the pool 1 to reduce the sliding resistance when the support column 20 rotates. It is configured to be. In addition, as a material to be used for the sliding member 23 having a small sliding resistance, a fluororesin, for example, Teflon (trade name) is suitable, and a bearing can also be used.

Further, the seat 2 has a plate body 2a having a concave spherical portion at the center fixed to the bottom 1c of the pool 1 where the support column 20 is erected via anchor bolt nuts 2b and 2c. ing. Of course, if the desired durability can be expected,
Alternatively, the corresponding position of the bottom 1c of the pool 1 may be simply recessed.

At the upper end of the support tube 21 on the lower end side thus configured,
The lower end of the support tube 22 is screwed.

That is, a female screw 21b is provided on the inner periphery of the upper end of the support tube 21 on the lower end side.
A male screw 22b that is screwed to the female screw 21b is formed on the outer periphery of the lower end of the support tube 22 on the upper end side, and the two screws 21b, 22b are screwed together. Thus, the upper and lower support tubes 21 and 22 are integrally connected.

On the other hand, a pulley 30 is detachably attached to the upper end of the support tube 22 on the upper end side.

That is, a spline joint 22c is formed on the outer periphery of the upper end of the support tube 22 on the upper end side, and the spline joint 22c
A pulley 30 is detachably mounted on the vehicle.

The pulley 30 has a spline joint 30 at its center.
The spline coupling portion 30a and the spline coupling portion 22c are detachably coupled to each other, so that the pulley 30 is detachably mounted on the upper end of the support tube 22 on the upper end side.

The pulley 30 has a groove 30b formed in a V-shaped cross section on the outer periphery thereof, and a connecting member 40 such as a wire rope is wound twice in this groove 30b so that a slip does not occur. Is equipped.

By the way, the pulley 30 around which the connecting member 40 is wound
Is attached to the upper end of each of the support columns 20, respectively,
Therefore, when one pulley 30 is turned, the other pulleys 30 are also turned synchronously.

As means for rotating the pulley 30, either manual operation using a gear or power operation using a portable motor can be applied.

Next, a case where the lid 10 is raised to a predetermined position by the lid device such as the pool configured as described above will be described.

As shown in FIG. 1, after removing the caps 11 from the screw holes 10a provided at the four corners of the lid 10 placed on the bottom 1c of the pool 1, the support pillars 20 are respectively inserted into the screw holes 10a. Screw.

Next, a pulley 30 is mounted on the upper end of each support column 20, and one connecting member 40 is wound between each pulley 30 in a state of being wound twice.

Then, one pulley 30 is turned by an appropriate turning means.

Thereby, each support column 20 rotates synchronously, and as a result, the lid 10 moves up along the support column 20. At this time, since the sliding member 23 is provided at the lower end of each support column 20,
Each support column 20 can be synchronously rotated with a small rotation operation force.

After the lid 10 is raised to a predetermined position in this way, the connecting member 40 wound around the pulley 30 at the upper end of each support column 20 is removed, and each pulley 30 is connected to each support column 20.
By removing the top 1 from the upper end, the lid 1 can close the opening 1a of the pulley 1.

When lowering the lid 10 again from the predetermined raising position, the lid 10 can be easily lowered to the bottom 1c of the pool by performing the operation in the reverse order.
