EP0959203A2 - Swimming pool gutter, specially from ceramic material - Google Patents

Abstract

The noise generated by overflow water slopping over the gutter side wall (3) nearest the swimming pool (10) is reduced by providing an articulated, angled and/or sloping support (9) on the inside of this wall for the grate (6), so that overflow water runs down the inside of the wall. The gutter is preferably made from ceramic material and is assembled from individual blocks to form a U-shaped gutter open on the top side. The gutter side wall nearest the pool is higher than the side wall (2) furthest from the pool. The gutter is covered by a grate resting on top of the side wall furthest from the pool and a support region on the inside of the opposite side wall.

Description

The invention relates to a swimming pool gutter, in particular made of ceramic Material as described in the preamble of claim 1.

It is already known to use pool heads of swimming pools and the like to provide such a swimming pool channel arranged all around the pool, in which the overflow water is collected, in the splash water tank passed and returned to the pool after cleaning or filtering. These swimming pool channels are mainly made of ceramic manufactured, the pool gutter stones used for this in one piece Made of ceramic material and one behind the other for formation the swimming pool gutter.

For reasons of hygiene, it is especially intended for the public Baths the amount of water in circulation increased more and more, per Unit of time to be able to clean more pool water. This is done via the Water flowing down the pool near the pool is collected in the swimming pool gutter and through drain openings formed in the bottom of the swimming pool channel fed to the splash water tank of a central pumping and cleaning station, from where the water returns to the pool after appropriate cleaning is returned.

In the past, water circulation rates of around 1 - 3 m ³ / hour per m were sufficient, but efforts are being made in modern pools to work with larger amounts of water circulation rates, namely up to 9 m ³ / hour per m. In conventional gutter systems, however, the outflowing pool water leads to annoying noise, which is mainly due to the fact that the water flowing out over the side wall of the pool gutter stone breaks in its flow and falls like a waterfall onto the bottom of the pool gutter.

The object of the invention is therefore a swimming pool gutter in particular ceramic pool gutter stones with those caused by the overflow water create less noise, so that even at higher Amounts of water in circulation do not simultaneously increase circulation noise occurs. This task is to be carried out with a structurally simple and above all that ceramic building principle can be solved.

This object is achieved by the characterizing features of the patent claim 1 solved, expedient embodiments by the subclaims are described.

With the measures according to the invention it is advantageously achieved that even with increased water circulation and thus increased amount of water, which over the upper edge of the side wall near the basin flowing overflow water in particular flows off in the area of the shoulder adhering to the channel wall So it does not break and falls like a waterfall with increased noise the bottom of the pool gutter falls.

It is particularly advantageous here if the one serving as a support for the grate Shoulder of each swimming pool gutter stone in its longitudinal direction like this is broken down tooth-like that open channels for the outflow of the overflow water arise. It is expedient to cross-section the open channels Rectangular or trapezoidal with straight or rounded sides to train, the latter channels preferably from the inside out decrease their clear width so that the bulk of the overflow water as close as possible to the side wall near the basin, and sticking to it flows out.

A similarly positive effect can also be achieved if you look at the cross section of the open channels according to the shape of a symmetrical hammer head trains. Here too the bulk of the overflow water becomes immediate on the side wall near the basin, there are channels that extend there.

Another option for dampening the overflow water is then given if the shoulder of each swimming pool gutter stone that serves as a support for the grate in its longitudinal direction by spaced apart closed channels is broken down, which expediently can be round, trapezoidal or semicircular in cross section. It should be noted here that with the last-mentioned cross-sectional shapes the closed channels extend from the side wall to the inside of the gutter stone taper to favor adherence of the overflow flow.

Another way to silence the overflow water received, the measure is that following the for the grate as a support serving surface of the shoulder of the side wall near the pelvis an inclined surface for the outflow of the overflow water to the channel bottom. Here the inclined surface should be at least larger with the vertical Include 12 °, especially greater than 15 °, with a range of 25 ° to 40 °, in particular from 30 ° to 35 ° is preferred.

Furthermore, the overflow flow is influenced favorably in that the transition between the shoulder surface and the adjacent one Side part of the side wall near the pool is formed by a curve, which have a radius in the range of 5-15 mm, in particular 6-9 mm can particularly preferably have 7.5 mm, whereby the grate advantageously in a small distance, in particular about 4 mm from the side wall near the pool is held. But it is also possible to at least make this transition to form two wavy adjoining curves, one of which the curve near the basin has a radius in the range of 5 - 15 mm, in particular 6 - 8 mm and particularly preferably 7.5 mm and the other curve a radius of 2 - 15 mm, in particular of 4 - 8 mm, preferably 4.5 mm having.

A further favorable influence on the overflow flow is achieved if the support area of the shoulder for the grate opposite the horizontal Bottom of the grate is formed inclined downward, so that it only points or lines on the shoulder, the maximum Distance between the inclination of the support area and the bottom of the grate 1 to 2 mm, preferably about 1 mm.

Furthermore, it can be advantageous in terms of production technology as a support for the Rust-supporting shoulder of each swimming pool gutter stone as a separate insert to train. For this purpose, the side wall near the basin can be an in Have longitudinal recess of the gutter, in which the insert strip can be inserted in a positive and / or non-positive manner. The recess is expediently dovetail-shaped for this purpose, the insert strip also made of plastic or another non-ceramic Material can exist.

Finally, the water drainage noise can be reduced by using a grate in the support area on the bottom and front has at least some of its grate bars support nubs. Another The combination would be able to dampen the water overflow noise a swimming pool gutter without a special shoulder for supporting a grate train and instead to provide the grate with support feet.

The conventional swimming pool gutter stone 1 shown in FIG. 1 has one essentially U-shaped cross section, which is limited by two opposite side gutter side walls 2 and 3 and the gutter bottom 4, in which drain openings 5 are arranged approximately in the center of the floor. The with 6 designated grate from transverse parallel grate webs 7 and longitudinal support rods 8 is on the one hand on the upper edge of the tank distant Channel wall 3 and, on the other hand, is supported on a shoulder 9 the gutter wall 2 near the basin, which serves as a support for the grate 6. How illustrated by arrows, pool water flows from a pool 10 over one upper edge 11 of the gutter side wall 2 near the basin into the interior of the gutter and falls on the channel bottom 4, resulting in corresponding overflow noises leads. Roughly the same situation applies to the conventional swimming pool gutter stone 2 to.

According to newer knowledge, the overflow noises become annoying that with increased water circulation and thus an increased amount of water, the The water flow flows over the upper edge 11 of the channel wall 2 near the basin especially in the area of the shoulder 9 no longer on the channel wall adheres, but breaks off and thus the overflow water like a waterfall falls on the bottom 4 of the channel 1. The latter is the conventional one Pool gutter stones given in FIGS. 1 and 2.

In contrast, the present invention achieves noise reduction of the Overflow water, even with increased water circulation, as in the following is described in more detail:

3 is therefore the shoulder 9, which serves as a support for the grate 6, in individual shoulder sections broken down in the longitudinal direction of the gutter stone, in particular in tooth-like members or projections or lamellae, the individual sections in FIG. 4 being designated by 12. Between Shoulder sections 12, which together serve as supports for the grate 6, remain Spaces 13 which form open channels and for the drain of the Serve overflow water from the pool. Here the water flows out of the Basin 10 over the upper rounded edge 11 of the channel wall near the basin 2 and flows around the shoulder sections essentially like a bridge pier 12 by draining most of the water through the channel-like spaces 13 flows downwards and thus on the channel wall, i.e. the inner surface the gutter wall 2 near the pool adheres and is thus a waterfall-like Impact of the water on the channel bottom 4 is avoided. Each after execution, a small amount of water flows over the shoulder sections 12, but this flowing water remains stuck as a residual amount and this does not result in a waterfall-like splashing of the water. The width the broken down shoulder sections 12 and the width of the intermediate distances 13 are chosen appropriately, in line with the Water circulation quantities per unit of time and length and the design of the gutter stone as well as the rust formation if necessary.

5, the shoulder 9 remains as a continuous Preserved bar on the gutter wall 2 near the pool, but are in the bar spaced openings 14 through which the Overflow water flows down to the channel bottom 4 and thus quasi the shoulder sections 15 remaining between the openings 14 in the manner of a bridge arrow flows around and thus on the inner surface of the channel wall near the basin 2 remains liable. Any overflow water, which as a residual amount over the Shoulder 9 runs is of such a small amount that it is on the inner surface of the Channel wall 2 sticks and therefore no waterfall effect occurs. As well as in the case of the shoulder sections 12 and spaces 13 are also in In the case of the opening 14, the opening cross sections can be chosen as desired, if for one sufficient drainage is provided across the gaps so that the remaining Support sections for the support of the grate 6 like a pier flow around.

7 shows a structurally different solution compared to FIGS. 3 to 6, in that an inclined surface 16 following the shoulder-like support surface 9 connects, through which the water is then directed towards the channel bottom 4 becomes. Here is the angle that the inclined surface 16 with the vertical includes, at least greater than 12 °, but in particular greater than 15 °, preferred ones Angle that encloses the inclined surface with the vertical in the area from 25 ° to 40 °, in particular in the range from 30 ° to 35 °.

3 to 8 is indicated by the solid arrows that the Overflow water due to the shape of the swimming pool gutter as a result Breakdown of the support shoulder 9 or connection of an inclined surface to the Shoulder 9 adheres to the inner surface of the inner channel wall 2 and thus no waterfall-like impact on the floor 4 takes place.

9 shows a detail in the region of the upper edge of the channel wall near the basin 2, the transition from the upper edge 11 to the shoulder 9 by a Rounding 17 is formed, which has a radius of 7.5 mm, in particular but in a range of 5 - 15 mm, and particularly preferably in the range from 7 to 7.5 mm. This results in a with the support of the grate 6 18 designated free space to the opposite inner surface 19 of the channel wall 2, which means that the overflow water is no longer essentially on the grate 6, but the grate 6, which due to the rounding 17 in is kept a certain distance from the inner surface 19, flows around, namely flows through the free spaces between the grating webs 7, that is, these flows around like a bridge pier and runs downwards. Here is the free one Gap 18 between grate 6 and inner surface 19 preferably in the range of 2 - 15 mm, especially in the order of about 4 mm, which also it is ensured that the overflow water on the inner surface of the pool Channel wall 2 adheres and no longer falls like a waterfall Channel bottom 4 hits. This training according to FIG. 9 is also related useful with the embodiments of FIGS. 3 to 8, namely especially with increased water circulation, because then there is a free space between the grate 6 and the inner surface of the channel wall near the basin 2 is guaranteed, which in connection with FIGS. 3 to 8 measures underlined and supplemented.

It is also expedient if the edge denoted by 20 is also rounded is formed, which favors the sticking of the water flow. It it goes without saying that the effect increases with increasing radius, ie the Noise reduction still increases.

Fig. 10 shows an embodiment in which an alternative to the rectangular 4, the shoulder members 12 'trapezoidal are shaped and preferably increase in width from the inside out. This creates protrusions between the shoulder sections 12 ' 12 'corresponding to trapezoidal channels 13' which in the area near the Inner surface of the channel wall 2 near the basin has the largest channel cross section have, the channel width decreases towards the outside. Here, the Side surfaces of the channels straight (Fig. 10) or rounded (Fig. 10a) formed his. This is a maximized channel cross-section for the outflow of overflow water given in the area of the inner surface of the channel wall 2. These embodiments are particularly suitable for increased amounts of water in circulation. Of course, the embodiment can be modified, the The principle is that the channel cross section is maximized in the area the channel wall 2 is achieved in that for the support of the grate responsible projections 12 'increase in width from the inside out and thus the channel width of the spaces 13 ', which are used for the drain of the water is available, in the area of the inner surface designated 19 the channel wall 2 is the largest.

', erreicht wird. Spiegelbildlich dazu besitzen die mit 12'' bezeichneten Vorsprünge einen entsprechenden Querschnitt.Another alternative embodiment with respect to FIG. 4 is shown in FIG. 11. Here too, the aim is that the channel cross-section is greatest in the area as close as possible to the channel wall 2, which is indicated by a cross-section of the open channels in the form of a symmetrical hammer head, designated 13

'is achieved. As a mirror image of this, the projections denoted by 12 ″ have a corresponding cross section.

FIG. 12 shows an alternative to the embodiment according to FIGS. 5 and 6, the openings here, as modified from FIG. 6, no longer having a round cross section, but a cross section that extends from the inside to the outside, that is to say from the inner surface of the channel wall 2 tapers away, so that the larger drainage width of the channel is in the region of the channel wall 2. The openings can expediently have a trapezoidal cross section (14 ') or semicircular cross section (14 ) or the like.

Fig. 13 finally shows a modification of the one-piece ceramic version the support shoulder as an insert component, which is manufactured separately and subsequently inserted in a corresponding recess in the swimming pool gutter stone is, for example, dovetailed or executed accordingly can be. The attachment is made by positive or non-positive or by both, ie positive locking and gluing and the like. This possibility has the advantage that the support shoulder, which according to the embodiments 3 to 6 or 10 to 12 can be made of plastic or other material can be made. The water flows here through the gaps between the shoulder sections as through the dashed arrow F is marked. The dovetail-shaped recess in the channel wall 2 is designated 21, in which the designated 22 separate insert strip is inserted.

13 is also an advantageous variant of a transition between the Support area of the shoulder 9 and the adjacent side part of the pool near Side wall 2 shown. This is defined by at least two contiguous waves Rounding 17 'and 17' 'formed. Here, the pool near Rounding 17 'a radius of 5-15 mm, preferably 7.5 mm, and the other rounding 17 '' a radius of 2-15 mm, preferably 4.5 mm. Hereby is advantageously achieved that the support area serving for the grate 6 the shoulder 9 opposite the horizontal underside of the grate down is inclined so that it is only punctiform or linear on the Shoulder rests and the water drain over the support shoulders through the Rust is only slightly disturbed.

As already stated, the alternative measures can be taken individually as well can also be used in combination. For example, in one embodiment FIG. 3 shows the rounding relationships according to FIG. 9 or partly from Fig. 9, can be realized, for example, for the embodiment according to Fig. 7 applies. Of course, the embodiments can be in one piece, So ceramic with the swimming pool gutter or as a separate one Insert part according to FIG. 13 may be provided.

Tests have shown that in particular with embodiments in which the support shoulders have a slight inclination, significant noise reduction are achievable, and this applies to both conventional as well as for all pool gutter stones shown here.

Finally, tests in connection with the embodiment of the Fig.10 that there are particularly favorable values if the outer dimension of the projecting shoulder sections 12 ', which is denoted by f, 13.5 mm and the sections i between them are about 6 mm. The dimension g, i.e. the Width between the shoulder sections 12 'in the region of the channel wall 2 is 12 mm, where h is 7 mm.

FIG. 14 shows an embodiment in section through a side wall near the pool, a grid with support knobs is placed on the support shoulder. The The grate 6 'is in this case connected to a base by support knobs 6' 'formed on the bottom Ring shoulder 9 supported in the form of a continuous bar on the channel wall 2, so that the grate is kept at a distance. The lateral spacing takes place via laterally formed or formed support knobs 6 '' '. The water flow thus takes place in the area between the grate and the channel wall Space.

Figures 15 and 16 show an embodiment in which the grate 6 '' '' on the one hand rests or is supported on the upper edge of the side wall 3 remote from the basin is and on the other hand in the area of the side wall 2 near the pool with 22 designated support feet, which are arranged separately or formed on the grate can, is supported. The support feet 22 are supported on the pelvic floor 4 from. The water flow with the advantages according to the invention is indicated by arrow 23 featured. Of course, if necessary, the grate can also be in the area the side wall away from the basin is supported by support feet and the like his. In this case, the shoulder 9 is not necessary.
