Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a water supply device for a swimming pool that connects to a water pipe and a water tank to supply water into the pool.

(Prior art) Conventionally, in a pool water supply system, a water supply pipe buried inside a deck is extended into a starting platform that is integrated with the deck, and the water outlet of the water pipe is opened at the surface of the starting platform facing the pool. It is known that the water supply pipes do not run over the decking, making it safer to walk by the pool.
1738 Publication, Utility Model Application Publication No. 113431/1983).

(Problem that the invention aims to solve) By the way, in swimming schools, etc., people often practice basic movements such as flipping, splitting, and closing legs by putting their hands on the edge of the deck, so it is necessary to ensure a long overall length of the edge of the deck. It is preferable that the starting stand is removable due to the nature of the peeling, and the need to prevent deterioration of durability due to the out-of-season natural environment in the case of outdoor peeling.

However, a deck-integrated starting platform in which a water supply pipe buried in the deck portion is extended cannot be removed, and cannot meet the above-mentioned needs.

Of course, it is proposed that a water supply pipe buried in the deck be extended into the removable starting platform.
It is necessary to devise a structure for attaching and detaching the water supply pipe section inside the starting platform and the water supply pipe section buried in the deck section.

The present invention was developed in view of the above-mentioned conventional circumstances, and although its purpose is a starting platform with a part of the water supply pipe installed inside, it is possible to remove the starting platform along with the water supply pipe as necessary. The goal is to make it possible.

(Means to solve the problem) The technical measures taken to solve the above problem are:
An internally hollow starting platform that has an inspection port that can be opened and closed on one side and a communication port on the bottom, a mounting bracket that attaches the bottom of the starting platform to the deck surface, and a recess on the deck surface facing the communication port. a bent water supply pipe having a lower end inserted through the communication port and positioned within the recess and an upper end facing outside from the pool-facing surface of the starting platform; A water supply pipe that stands up from below the deck surface and has its upper end located in a recessed part, and a connecting fitting that connects the upper end of the water supply pipe and the lower end of the water supply bent pipe with the communication port as a work space. It is.

(Function) According to the above technical means, the starting platform having the water supply bent pipe inside is removed by opening the inspection port and releasing the mounting fittings and the connecting fittings by operating from inside the starting platform.

(Effects of the Invention) Since the present invention is configured as described above, the starting platform having the water supply bending pipe therein can be removed together with the water supply bending pipe by operating from inside the start stand.

Furthermore, by covering the concave portion with a cover body after removing the starting platform, the upper end of the water supply pipe rising from below the deck surface can be hidden without protruding above the deck surface, and post-processing is also easy.

(Example) Next, an example of the present invention will be explained based on the drawings _.
1 is a water supply pipe, and 4 is a water supply bent pipe connected to the water supply pipe 1 and housed in the start board B.

The starting platform B has a hollow box shape, and has an inspection port 18 that can be opened and closed on any side except for one side, that is, the surface facing the pool _b1 , and has a communication port _b3 of a desired area on the bottom surface _b2 . The bottom surface B ₂ surrounding the communication port B ₃ is attached to the deck surface A ₁ with a mounting bracket 16 .

The lower end of this mounting bracket 16 is screwed into the screw hole 16b' of a fixing seat 16b with a screw hole 16b' which is fixed flush to _the deck surface _A1 just below the insertion hole 16a opened at the four corners of the bottom surface B2. It consists of a screw rod 16c whose upper end projects into the starting block B from the insertion hole 16a, and a fixing nut 16d and a loosening nut 16e that are screwed onto the screw rod 16c to tighten the four corners of the bottom surface _B2 . There is.

Water supply pipe 1 connects with the water pipe and water tank and connects to the deck surface.
Piping is installed in the space below A ₁ and raised up through the bottom of the recess 3 provided on the deck surface A ₁ facing the communication port B ₃ , and the upper end thereof having the connecting flange 1a is inserted into the recess 3. It is located. The water supply bending pipe 4 is an elbow pipe, has a connecting flange 4a at the lower end, and has an upper end facing outside from the pool facing surface _b1 .

This bent water supply pipe 4 has a box body 5 having a substantially U-shaped cross section fixed to the back side of the mouth of a water discharge port 2 opened on the surface facing the pool _b1 , and a fitting hole 6 opened on the rear surface 5a of this box body 5. Fit and fix the tip to the water supply pipe 1 so that the water supply port 4' faces the water discharge port 2, and the lower end is positioned in the recessed part ₃ through the communication port b3, and the connection flange 4a is connected to the water supply pipe 1.
It is adapted to engage with the connecting flange 1a. A stepped portion 7 is formed in a desired range of the pool-facing surface b _{1 including the water outlet 2} by recessing it one step toward the internal space side of the starting platform B, and a front plate having elongated water supply holes 8 a in multiple steps in the height direction. 8 is fitted into the stepped portion 7 and is secured with a screw 9, thereby preventing direct viewing of the water supply port 4'.

The connecting fitting 19 includes a bolt 19b which is inserted through a hole 19a formed in the connecting flanges 1a and 4a and whose head 19b' is fixed to the lower surface of the connecting flange 1a of the water supply pipe 1.
The connecting flange 1a is screwed onto the threaded rod 19b'',
It consists of a fixing nut 19c for tightening 4a and a locking nut 19d. In the figure, 10 is a water supply operation handle, and 11 is a deck edge.

In this embodiment, when removing the starting platform B having the water supply bent pipe 4 inside, the inspection hole 18 is opened and hands or tools are allowed to enter, and the locking nut 16e of the mounting bracket 16 is tightened in the internal space. , loosen the fixing nut 16d, and use the connection port _B3 to loosen the locking nut 19d and fixing nut 19c of the connection fitting 19.
All you have to do is solve.

After removing the starting platform B, the screw rod 16c of the mounting bracket 16 is pulled out from the fixing seat 16b, and the recessed part 3 is closed with the lid body 12 having leg pieces 12a of the same height as the recessed part 3. The part 3 is covered so that the upper end of the water supply pipe 1 does not get in the way.

FIG. 5 shows a modification of the connection fitting 19, in which a cap nut (described below with reference numeral 19) is used as the connection fitting 19.

In place of the connecting flange 1a at the upper end of the water supply pipe 1, a screw 1b is screwed onto the outer peripheral surface, and the bent water supply pipe 4 is fitted into the water supply pipe 1 by making the pipe diameter slightly smaller without providing the connecting flange 4a at the lower end. A cap nut 19 is screwed onto the screw 1b of the water supply pipe 1.

In this embodiment as well, the connection between the water supply bent pipe 4 and the water supply pipe 1 is released by manually unscrewing the cap nut 19 using the communication port _b3 .
