Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a pool floor that is submerged in a pool and used to change the depth of the pool.

(Prior Art) In the case of conventional pool floors, the length of the legs is fixed, so while it is possible to adjust one type of depth, it is impossible to adjust other depths. Ta.
For example, a pool floor as seen in Utility Model Publication No. 49-836 has already been proposed, but the height of this pool floor can be adjusted by adjusting the opening degree of its legs. It is said that it can be adjusted. However, since the legs of this pool floor are formed into a triangular shape by a single plate, it is certainly possible to finely adjust the apex by adjusting the opening degree of the legs. However, this is just a fine adjustment for the level difference in the top surface of the floor that tends to occur when multiple pool floors are installed, and the purpose is different from the height adjustment of 10 cm or 20 cm that is considered in this invention. It is. Therefore, as described in the above-mentioned publication, in order to make the inside of the pool a desired depth, it is necessary to stack a plurality of pool floors on top of each other. By the way, in recent years, swimming pools have become more popular, and for example, as shown in Figure 7, there is a pool P that is deep near the diving board and becomes shallower as it moves away from the diving board. As shown by the imaginary lines in the figure, swimming schools have partially shallow pools that can be used by many people at the same time, depending on the situation, not only adults but also children who are not yet able to swim. There is a strong desire to do so. In such a case, pool P
It is necessary to adjust the bottom of the pool to a depth of at least 10 cm, but this cannot be done with conventional pool floors with fixed leg lengths. That is, with the conventional pool floor, it is not possible to form a necessary shallow horizontal surface within the pool P.

Alternatively, as shown by the imaginary line in FIG. 8, even if a relatively deep pool P can be used as appropriate depending on the game content, if the length of the legs of the pool floor is fixed. However, it is necessary to prepare multiple types of pool floors with different heights, which is inefficient in terms of cost and storage space.

In order to solve the above problems,
Publication No. 38352 proposes a "pool auxiliary stand" in which the base ends of the legs can be folded toward the top plate. In this ``swimming pool auxiliary stand,'' the leg installation board is movable in and out of the screen body, so that the height and inclination of the top plate can be adjusted.

By the way, this type of "pool floor" is used by being submerged in the pool, and must be stable against waves and the like that occur within the pool. In other words, water currents and waves are generated in a pool due to the movement of many people, and this type of "pool floor" must be made so that it does not move even when subjected to the force of such water currents and waves. It is. On this point, the "pool auxiliary stand" mentioned in the above publication only supports a top plate that has a large area and is susceptible to waves and other forces using extremely thin legs, even though the height is adjustable. Therefore, it is very easy to move when submerged in a pool.

(Problems to be solved by the invention) This invention was made in view of the above-mentioned circumstances, and the problem to be solved is to easily adjust the depth of various types of pools. To provide a pool floor that is stable in a pool and has a simple structure.

(Means for Solving the Problems) The means taken by the present invention to solve the above-mentioned problems are explained using the reference numerals used in the examples. 10 are connected to each other and fixed under the top plate 10. A pool floor 100 includes a plurality of plastic base bodies 20, which are connected to each other and fixed under the top plate 10. a bottom portion 26 integral with the bottom portion 26 having an opening 20a;
The screen body 20 is formed into a roughly box-like shape, and the outside and the screen body 2
The leg portion 21 has an opening 21a that communicates with the inside of the leg portion 21.
A swimming pool floor 100 is characterized in that an auxiliary leg part 40 for adjusting the height can be selectively fitted to each leg part 21.

Next, this means will be sequentially explained according to specific examples shown in the drawings.

As shown in FIGS. 1 and 2, the pool floor 100 according to the present invention has a plurality of top plates 10 shown enlarged in FIG. A plurality of script bodies 20 are fixed under these pool floors 100 by joining them together.

Each upper plate 10 is made of plastic, and has a large number of linear anti-slips 14 formed on its upper surface, and as shown in FIGS. 3 and 6, in the longitudinal direction of its lower side. is a hanging side part 12 for preventing slippage to be locked to a fixed angle 30 to be described later.
and a central locking side portion 13 that is further connected and fixed via a connecting member 15.

As shown in FIGS. 4 and 5, the script body 20 is approximately box-shaped, and has four inverted triangular side walls and a bottom portion 26 integrally formed of plastic. That is, this script body 20 is
It has a box shape with four inverted triangular side walls and a bottom 26 that are open at the top to form a large storage space for pool water. Pool water is allowed to enter through holes 23 and the like. Also, this script font 20
When the pool floor 100 is taken out from the pool P, the water inside is discharged from the large opening 20a formed in the bottom 26, and air enters through the through hole 23 to facilitate the discharge of this pool water. It is something.

A plurality of cylindrical legs 2 are provided at the lower end of this script body 20.
1 is formed, and an opening 2 of each leg 21 is formed.
By fitting the rubber cap 22 into the pool floor 1a, the rubber cap 22 is attached to the pool floor 10.
This prevents the 0 from slipping when submerged in the pool P. Further, each leg 21 has a constant diameter in the vertical direction, and furthermore, the auxiliary leg 4 described later
0 is chamfered to make it easier to fit. On the other hand, through holes 23 are formed at the same position on the four sides of each script body 20, and an intrusion prevention bar 31 can be inserted into these through holes 23.

Further, at the upper end of the script body 20, a central locking side 1 is provided in a direction perpendicular to the longitudinal direction of the upper plate 10.
A stop portion 24 having a small protrusion 24a that receives the fixed angle 30 and is forcibly fitted onto the fixed angle 30 is formed to protrude upward. A gap 25 is formed for forced fitting. Also,
The bottom part 26 of this script body 20 is in a horizontal state, and a part thereof has a large opening 2 for ingress and evacuation of pool water, as shown in FIG.
0a is formed.

When adjusting the height of the pool floor 100, as shown in FIG.
The auxiliary legs 40 made of plastic are fitted and fixed. These auxiliary legs 40 are cylindrical, and their upper ends fit into the outer periphery of each leg 21, and their upper end surfaces are connected to the bottom 26 of the script body 20.
After being positioned by abutting against it, it is fixed by means such as screws 41, for example. Of course, each auxiliary leg 4
The inner diameter of the upper end of the pool P is made to match the outer diameter of each leg 21, and by preparing a wide variety of auxiliary legs 40 with different lengths, it is possible to It is now possible to handle various shapes. Note that a rubber cap 22a is fitted to the lower end of each auxiliary leg portion 40.

(Embodiment and operation) First, the method of assembling this pool floor 100 will be explained with reference to FIG. 6.

(a) After attaching the side plate 11 to the fixed angle 30 with the connecting member 15 fixed in a predetermined position in advance, a plurality of (in this example, five) upper plates 10 are sequentially inserted into the connecting member 15. to form the top plate. Then, both the left and right short sides are joined by a guide plate.

(b) Next, each script body 20 is attached by positioning and engaging the central locking side portion 13 of each top plate 10 with the central notch of the locking portion 24 projecting upward, and also inserting the fixed angle 30 into the gap 25. After the hanging sides are forcefully fitted, the floor 100 for the pool is completed by fixing the script body 20 to the top plate using fixing means such as screws.

In this way, the pool floor 100 is completed by fixing three sets of six screen bodies 20 in total to the five upper plates 10.

A method of using the pool floor 100 configured as described above will be explained below. This pool floor 1
Of course, if the 00 is submerged in the pool P, the depth of the pool P can be adjusted by itself, that is, without using the auxiliary legs 40.
When this pool floor 100 is submerged in the pool P, the pool water enters the base body 20 through the large opening 20a provided at the bottom 26 of the base body 20, and the air flows through the through hole formed in the side wall. 23, the work of sinking the pool floor 100 can be done within a single hour. And the pool floor 100 submerged in the pool P in this way
The pool P is stable in the pool P because all the screen bodies 20 formed in a roughly box shape contain pool water. That is, this pool floor 100 has a large inertia due to the water that has entered into each of the floor bodies 20.
It is stable and is not affected much by the water currents and waves that occur within the pool P.

In addition, if it is desired to form a shallower bottom part in the pool P than the bottom part formed by the pool floor 100 that does not use the auxiliary legs 40 as shown in FIG. The auxiliary leg parts 40 of the same length may be fitted and fixed to each leg part 21, respectively. Of course, in this case, the length of each auxiliary leg portion 40 is selected so that the top plate 10 of the pool floor 100 has a required height within the pool P. As a result, bottom surfaces with different depths are formed at the bottom of the pool P as shown by the imaginary lines in FIG.

In addition, when the bottom surface of the pool P is inclined as shown in FIG. 7, the same pool floor 100
Even in such a case, the auxiliary legs 40 of different lengths of the legs 21 located on the left and right or front and back of the pool P may be fitted together so that each top plate 10 is horizontal in the pool P. . When making this height adjustment, it is advisable to not only use auxiliary legs 40 of different lengths as described above, but also consider the installation location of the pool floor 100 itself. Considering the installation location of the pool floor 100 in this way,
This is effective, for example, when the angle of inclination is not constant, such as at the bottom of the pool P shown in FIG. By doing so, a bottom portion having a constant depth as shown by the imaginary line in FIG. 7 is formed.

Note that the upper plate 1 constituting the pool floor 100
Since a large number of anti-slip elements 14 are formed on the top surface of the device 0, even if the top plate 10 is made of plastic, the person riding on it can use it without his or her feet slipping. . Also,
Each of the leg bodies 20 is connected by an intrusion prevention cover 31, and this intrusion prevention bar 31 prevents a swimmer from sneaking under the upper board 10. Furthermore, each script body 20 has a through hole 23 formed on its side surface, and an opening 23 is formed on the lower side of the script body 20.
a is formed to allow water to enter and drain into the screen body 20 in a good condition. The supply and drainage of water to and from the pool becomes smooth, and the pool floor 100 can be taken in and out of the pool within a short period of time.

(Effect of the invention) As explained above, the pool floor 1 according to the invention
00 has each script body 20 roughly box-shaped so that it can hold a large amount of water, so when it is submerged in the pool P, it is stable and is not affected by waves etc. It can be installed so that it does not move easily. and,
If the auxiliary legs 40 are appropriately fixed to each leg 21 of this pool floor 100, the pool floor 100
The bottom of the pool P can be easily adjusted to various depths without changing the basic configuration of the pool P.
Further, in order to enable this depth adjustment, a plurality of legs 21 are formed at the lower part of the script body 20, and the auxiliary legs 40 are simply fitted and fixed to these legs 21. Therefore, the structure can be extremely simple, and it can be manufactured integrally from plastic.

Furthermore, as explained in "Assembling method" (a) and (b) of the above-mentioned (modes of implementation and operation), the installation work of the script body 20 is simple, so on-site assembly is possible, and transportation is easy. Since only the script body 20 can be packed separately, it can be transported extremely efficiently.
