Description

Description of the invention

The invention relates to the field of water filtration in swimming pool baths and more precisely relates to 2 filtering ladders for swimming pool baths.

Currently, there are many technical solutions that allow water filtration in swimming pool baths. Filtration is carried out with the help of one or more filters, the installation of which is generally combined with the pumping system of water intake and supply.

It was proposed, for example, to combine the installation for pumping and filtering water in one compact 70 block, which is mounted together with the panels forming the pool bath. One part of the block, including the filtering device, is located under water, and the other part, including the intake and pumping devices, is mounted outside the pool and combined with the aforementioned filtering device.

Such a solution is offered, for example, in the description of the patent EP-A-0145619. Part 79 immersed in water can include devices that simultaneously perform the function of ladder steps.

At the same time, for reasons of convenience, the consumer often wants to have a classic ladder in the pool bath, as a rule, of round shape, located on the edge of the bath! swimming pool There are stairs, bearing in mind their shape, they are more like stairs NOVEL.

It was also proposed to create a ROMAN filtering ladder based on the specified principle mentioned in patent EP-A-0145619. The submersible part has a rounded shape and combines the steps of the ladder with a filtering device. This submersible part is connected to the location above the ground level by a suction and injection device. The submersible part is not built into the panels of the pool, but is located on top of the latter and is designed in accordance with the rounded surface of the stairs.

After the installation and fastening of two parts of the stairs relative to the panels of the pool, between the back surface of the stairs and the front surface of the figured panels, there remains a free space, Ho) which is filled with water. Leaves and other impurities can accumulate in this space, which can lead to serious problems related to pool care.

Patent EP-A-0279140 can also be cited, which describes a module consisting of a pre-assembled kit made of polyester reinforced resin and including a ladder with several steps, M 30 of which provides a technical space and a tank for filtration. However, such a module is difficult to manufacture. In addition, problems may also arise during its operation! with sealing.

The purpose of the invention is to eliminate these shortcomings in a simple, reliable, efficient and rational way. M

The task of the invention is to obtain a filtering ladder that allows you to mount it directly together with the adjacent panels that make up the bath of the pool, characterized by reliable sealing, low cost, easily and quickly installed, ensuring high efficiency M of filtration and allowing to endow it with other functions.

To solve this problem, a filter ladder for a swimming pool bathroom was developed, which is distinguished by the fact that: "- the body of the ladder! forms a closed hollow volume, obtained by the method of rotational molding Z 70 (rotomoulding), for arranging a tank in it, c - the tank communicates with the bathroom, c" - the body contains internal devices, devices for installing systems! filtering, which communicates with the water in the tank, - on the side of the body, opposite to the one where the steps are located, there are means for mounting and 45 fastening of technical chambers, made by the rotomoulding method, in which devices for water intake and injection are mounted, combined with the filtering system , -and - on the side wall of the case there are devices for fastening adjacent panels of baths! swimming pool

The filter ladder is completely manufactured by the rotomoulding method, which is well known to specialists, but which has never been used for the production of a filter ladder. The technique of rotomoulding -I 20 turned out to be especially preferable in solving the given task, since it immediately

And" gives a completely hermetic tank, in which it is possible to mount filtering devices, combined with specific devices.

To solve the task of equipping the tank with a simple filtering system, internal devices are a problem! hardness, formed on the bottom of the tank directly when it was made, and which serve as a support for the bearing plates! with the connecting armature of the actual system

In the second version of implementation, a hollow space is provided at the bottom of the tank, formed from the back side of the stairs, which is limited by a raised bottom relative to the support base, which has an O shape and is hollow inside, while the raised bottom passes at the same level with the descent slots, 60 formed in thick counter march, and the inner hollow part is filled with light material, ensuring alignment with the raised bottom. The hollow space of the tank, bounded by a raised bottom, is blocked by a supporting technical chamber formed by a number of stiffening elements.

To solve problems! securing the device relative to the tank for the installation and fastening of chambers containing a suction and heating pump, represented, on the one hand, by racks formed during the rotomoulding of the tank on which the specified chamber rests, and, on the other hand, by a centering element interacting with a hole formed in the chamber, and the centering element is a hollow casing in which suction and discharge pipes are placed.

The second task that the invention solves is to give the filtering ladder other functions.

For this purpose, one of the steps at the level of its horizontal surface is equipped directly during rotomoulding with ribs limiting the hollow space in order to ensure air intake through a pipe connected to the device located in the technical chamber, and this step 7/0 is equipped with a microperforated plate

To solve the problem of fixing the ladder in the whole length of the panels that form the bath of the pool, the provision of devices for fixing the adjacent panels, which are the side edges, in the body of the enclosures! metal inserts for the introduction of fasteners.

To solve the problem of installing a ladder, combined with a film that covers the inner part of the pool bath, on the front side of the tank, at the level of the steps, an O-shaped flange is installed, which is covered with material for a screw connection and a gasket for attaching the film, cut in the form of I and fixed with the help of screws, covered with a protective baguette (wooden bar).

According to the second feature, one of the counter marches is equipped with a rotomoulding device for installing, at least 2 mm, one searchlight.

"

As shown in the drawings, the housing of 1 filter ladder! forms a closed hollow volume, sv) obtained by the rotomoulding method, which fulfills the function of a reservoir and. On the front side of the tank. there are steps 15. In particular, in the plan view (Fig. 3), the body 1 has a semicircular shape as a whole, and in cross-section angular profile (fig. 5). In addition, there is 1 staircase in the building! directly when formed, a cavity 1s is provided for placing systems in it! filtering, which will be described later. ј5" For greater rigidity of the body, 1 is provided in it! during its manufacture, a number of horizontal Ia and vertical Te stiffness elements. ш- On the wall of the second case 1, opposite to the one where the steps 16 are located, provide! devices for І5" installation and fastening of technical cameras! 2, obtained by the rotomoulding method. This chamber has the overall shape of a parallelepiped. Devices from the side! walls 17 are racks 19, obtained by sh-shaped housing, protruding beyond the surface of the wall 1st. These racks 19 are two corner consoles on which the camera 2 is located. The wall 17 of the housing 1 also has a centering element at the level of the upper part, of a strictly rectangular shape, adapted for interaction with an additional hole formed in the camera 2. the centering element 1p is a hollow casing and allows you to install and lay suction TA and discharge TC pipes, which are mounted, as indicated below, in a combined with a filtration system and a pumping system.

F) The filtration system includes, at least, one filter capacity C (fig. 7), located in a glass 4 of cylindrical shape.

So the filtering device is connected to the supporting plate 5, which rests on two ribs 141 and Id2, because the formation is at the bottom of the tank. This bearing plate 5 is connected to the suction pipe TA by means of a curved pipe 6 located between two ribs 141 and 192.

One end to the pipes! passes through the plate 5 and is connected to the base of the glass 4, in which the filter capacity 3 is located, by means of a mesh fitting.

The other end 66 of pipe 6 exits at the level of the centering element 10. This is the end of pipe 6B! 6, coming out of 65 of the centering element 1, is hermetically attached with any lime and suitable methods to the pumping system located in the technical chamber.

More specifically, the suction pipe TA is connected to the intake device of the pump 7 located in the technical chamber 2. The pump mainly works at two speeds.

The discharge pipe TK is connected to the corresponding intake device of the pump 7 and with the help of a hermetic connection to the pre-installed nozzle 8 inside the tank 1a and ends in the form of a nozzle at the level of one of the counter-stairs.

The upper part of the glass 4 with the filter capacity Z is hermetically connected to the pillow 9, which in turn also has a rigid hermetic connection with the entire 1s, which carries the exclusive function of the equalizing capacity (pipe). 70 Thus, the entire filtration system (C and 4) is placed inside the tank and communicates with the pool water, which enters the tank through hole 11, equipped, for example, with a foam separator. That hole 11 is formed, for example, at the level of the upper counter march of the stairs.

Water from the pool fills the tank, and through hole 11, passes through filter 3, so! then absorbed by pump 7 through pipes 6 and TA and supplied by the same pump through pipes TKy 8.

It is obvious that tank 1 and chamber 2 can have different water filtration and pumping systems according to the above conditions. Cavity 1c in the form of an equalizing capacity communicates with an inspection hatch 1), closed by a seed cover 10.

Teaching that the body of stairs 1 and the technical chamber 2 are made by rotomoulding method, and specifically that the body of stairs 1 is filled in the form of a hollow element, the indicated chamber 2 is absolutely hermetically sealed relative to the body of stairs 1.

As indicated, body 1 fulfills the function of a reservoir and is therefore constantly filled with water coming from the baths! swimming pool In order to avoid the possible spread of microbes, etc., it is important to establish water recirculation and, therefore, avoid its stagnation. For this purpose, there are special devices at the bottom of the tank. with

As shown in fig. 11, 12 and 13, the bottom of the tank is a hollow container 1аі1 formed from the back! ladder, which determines the raised bottom 1a2 relative to the supporting i) base 1a3, which has an O-shaped shape and is hollow inside. The raised bottom 142 is absolutely smooth and located in a horizontal plane at the level of the bottom step of the stairs, so that it was located on the same line with the descent slots and formed in the depth of the corresponding counter march. The inner space of the support base 1aZ is filled with a light foam material M, which is covered, for example, with a layer of binding solution, also completely smooth, located at the level of the raised bottom 1a2. "Mr

On top of the raised bottom there is a grid (K) connected to the discharge pipeline. This grid forms jets of water, which wash away dirt, etc., from the bottom of the tank and remove it through slots 1 to 5 in the bath of the pool in order to filter them by recirculation. "Mr

These devices make it possible to avoid the stagnation of water and the development of bacteria, etc. in this way. at the bottom of the tank.

As already mentioned, the raised bottom 1a2 is formed due to the hollow element 1a1. In these conditions, so that the rigidity of the tank does not decrease, the hollow container is equipped with a supporting technical box 18, which is formed by a row of 18a rigidity elements. The supporting technical box 18 is fixed at the level of the 1st building of the ladder! by any known and adequate means.

And according to the second feature, one of the steps 15 is equipped at the level of the horizontal surface, and directly during production, with elements of rigidity 101, which limit the field of space with those to ensure the supply of air through the intake device connected with the help of pipes! 12 with the device located in the technical chamber 2. The step 106, equipped with stiffening elements 161, is equipped with a microperforated plate 13.

It is also planned to equip at least one counter-march device for

Sh - installation of at least one searchlight (PE) (fig. 1). The front side of the case 1 of the ladder at the level of steps 15 is equipped with an O-shaped flange. In the sole of the flange 1k, a groove 1k1 is formed, in which the material 14 for fastening the screws is fixed with the help of glue, closed with a gasket 15. Such devices allow you to fix the facing film І, і» cut in the form of ОО, with the help of screws, which are screwed in as indicated material 14. Baguette 16 is placed on top of the screw fastening.

As shown in fig.va, the material 14 for fastening the screws is preferably attached not in the groove, but outside, that is, inside the tank. there is no question of tightness as regards the angles of connections of various elements of the fastening material. (F, Finally, on the front wall of the housing 1 there are side edges, in which metal inserts are inserted for hermetically attaching the ladder block to the second panels P, which form the bath of the pool.

It is also possible to equip a section along the outer peripheral case of 1 ladder! with metal inserts for fastening vertical, distributed sections of trays for concreting.

It is obvious that the technical chamber 2, in which the pumping unit is located, is hermetically closed with the sealing cap 17.

The main advantages of the device, according to the invention, are as follows: - the use of the rotomoulding method allows you to get a ladder in the form of a completely hermetic 65-volume hollow element, - low cost of production,

- the possibility of enabling other functions,

- the possibility of hermetically assembling the filtering ladder unit together with the other panels of the pool baths.
