Definitions

  • the invention relates to a swimming bath pool according to the preamble of claim 1.
  • Such a swimming bath pool having a retaining wall is known from DE-A-2517337.
  • Said known retaining wall is at its lower edge pivotally connected to the opposing side walls of the swimming bath pool.
  • This known retaining wall is shiftable between a vertical, upright position to extend above the water level, and a substantially horizontal, retracted position to lie substantially flat with one of its side walls with the surface of the swimming bath bottom, to be received in a recess in said swimming bath bottom.
  • the known retaining wall is locked in its upright position by retention between cam-shaped stopper elements on each respective side wall of the swimming bath pool which, viewed in the longitudinal direction of the retaining wall, can engage with both sides of said retaining wall at its upper edge.
  • the known retaining wall is hollow, and can be filled with water or air respectively. By replacing the water by air, or visa versa, the retaining wall can be swung between its upright, active position and its retracted, inactive position.
  • a disadvantage of this known retaining wall is its rather poor connection with the structure of the swimming bath pool. On the one hand this yield a relative week and flexible retaining wall, which is a disadvantage for swimmers which use the retaining wall as an abutment for their feet if they turn around while fast swimming in a straight direction between the retaining wall and the opposing side wall of the swimming bath pool. Apart from that, for swimming competition, lines will be connected to the retaining wall and the opposing side wall of the swimming bath pool to divide the pool in several delimited tracks.
  • the known retaining wall due to its poor connection to the structure of the swimming bath pool, will give too much flexural displacement in the centre part, such that the length of the tracks is not the same, and the pool can not be used for tournaments.
  • connection of the retaining wall could be eliminated by increasing the flexural stiffness of the retaining wall itself, however this calls for a larger volume of the retaining wall, demanding further structural elements, such that increasing its flexural stiffness yields a substantial rise of capital investments and such a stiffening can not avoid a further disadvantage of this known retaining wall; in its upright, active position, its pivoting elements and its retainer elements will be relatively high loaded by for instance movements of the water, pressure differences due to differing water levels at both sides of the retaining wall, swimmers climbing on the retaining wall and diving there from, as well as the tension forces from the lines dividing the pool in several tracks.
  • the tension forces from such lines are typically 600 kilogram for each line or even higher, while a typical pool with a width of 25 m., there will be ten tracks, such that there are nine lines connected to the retaining wall amounting to about 6.000 kilogram tension forces to be carried by two pivots and two retaining elements.
  • this known retaining wall can for instance be eliminated on the basis of the understanding which is provided by NL-A-7207667, describing a retaining wall which is pivotally connected at its lower edge to the swimming bath pool, while at its upper edge being pivotally connected to a floating body.
  • This floating body can be levelled between a position projecting above the water level and a position in which the floating body is received within a recess in the underwater bottom, by means of pulling cables which can be lengthened or shortened.
  • the retaining wall follows the movements of the floating body.
  • Such a combination of retaining wall and a floating body connected thereto at each upper edge is used to, for instance to close the swimming pool, seal an outdoor part of the pool from an indoor part of the pool.
  • This known combination demands for a floating body with a relatively large volume, and a complicated and expensive mechanical drive system.
  • the retaining wall from this known combination is not loaded by swimmers or lines or whatsoever, since it is only in use when the pool is out of use.
  • the present invention is concerned with eliminating or decreasing the drawbacks of the retaining wall as indicated in the preamble, without the need for using additional floating bodies to maintain the small volume necessary for having a retaining wall such as is present with the retaining wall as indicated in the preamble or even to decrease the space consumption in the combination with a less complicated drive system to move the retaining wall between its retracted and projecting, upright position, respectively.
  • the present invention suggests, a retaining wall as indicated in the accompanying claim 1.
  • the retaining wall will have a substantial increased stiffness, such that flexural displacement of the retaining wall will be kept to a minimum under the load of swimmers, tension forces from lines, etc are decreased. Furthermore, there is a more even load distribution over the connecting- and retaining elements between the retaining wall and the swimming bad pool, such that those elements can be cheaper and demand less maintenance, while serving greater durability.
  • the connecting- and retaining elements can be continuous elements, extending over the complete swimming bath bottom, but can also be individual elements with a spacing of for instance one to four metres. Since there are no provisions necessary at the top of the side walls of the swimming bath pool, it can have a more attractive and safer design.
  • the retaining wall is integrated in a bridging part extending between parts of the swimming bath bottom at a higher and a lower level.
  • the retaining wall according to the invention can be used in combination with a swimming bath bottom of which the level is adjustable (a so-called adjustable floor), for which purpose the retaining wall can be connected to the adjustable part of the swimming bath bottom, and can be received in a recess in that movable part of the swimming bath bottom if in its retracted position.
  • a swimming pool with an adjustable floor is illustrated in EP-A-0532079, of applicant.
  • a swimming bath 1 having a rectangular building plan is shown. From the bottom 2 thereof, a retaining wall 3 extends upwards to above the water level 10.
  • FIG. 2 shows a more detailed view of the structure of the retaining wall 3 and the fastening thereof to the bottom 2.
  • the active position of the retaining wall 3 is shown by means of solid lines; the inactive position thereof by means of dash-dotted lines.
  • the retaining wall 3 is of hollow construction. Obviously, the wall 3 can also be of solid construction.
  • the retaining wall 3 tapers slightly from its base which is hingedly connected to the bottom 2 to its opposite free end.
  • a recess 4 is provided in the bottom 2, the profile section of which recess 4 corresponds to the profile section of the retaining wall 3.
  • the retaining wall 3 is provided with a hinge 9 along a longitudinal edge, which hinge 9 is connected to the bottom 2 at the upper longitudinal boundary of the recess 4, as shown.
  • a rubber sealing strip 5 is attached to the longitudinal edge opposite the hinge 9, at the base of the retaining wall 3. Said sealing strip runs in line with the respective side wall of the retaining wall 3. As is shown, said rubber sealing strip 5 seals off the gap between the underside of the retaining wall 3 and the bottom of the recess 4, in order to prevent, for example, swimmers from reaching the underside of the retaining wall 3. As a result of its flexible properties, the rubber strip or flap 5 will automatically fold against the base of the retaining wall 3 when the latter is hinged to its inactive position indicated by dash-dotted lines in Figure 2.
  • a drive arm 6 projects from the base of the retaining wall 3, which drive arm is bent at right angles at its end, as shown. Said drive arm is located, for example, halfway along the length of the hinge 9. Another fastening point can also be selected for the drive arm 6. It is likewise possible to use more than one drive arm 6, for example depending on the load and the deformation of the parts. Near the free end of the arm 6, a drive cable 7 is attached, which is guided, via a guide wheel 11, to a drive element, not shown in any more detail here, for example a hydraulic or pneumatic cylinder.
  • the degree of hinging of the retaining wall 3 about the hinge 9 from the inactive to the active position shown in Figure 2, is limited by a blocking element 8 which, in the position shown in Figure 2, interacts with the drive arm 6 in a blocking manner.
  • said blocking element 8 is integrated in the bottom 2.
  • the blocking element can also be adjustable in order to adjust the degree of swing of the retaining wall 3 about the hinge 9.
  • a protective rubber strip 12 is provided on the side of the recess 4 opposite the hinge 9, in order to prevent swimmers from hurting themselves.
  • the section of the bottom 2 which section is on the right-hand side in the drawing, is constructed at a lower level.
  • Said section can also be constructed, for example, to be adjustable in height. This height adjustment can be effected in any conventional way, for example as described in DE-A-25 56 026, reference being made in particular to Figure 1 thereof.
  • Said Figure 1 shows that the height-adjustable section of the bottom adjoins the fixed section of the bottom by means of a hinged flap. Said flap seals any gap between the upper side of the lower section of the bottom and the underside of the higher section of the bottom.
  • the retaining wall 3 can also be hingedly connected to a height-adjustable section of the swimming bath bottom 2.
  • FIG. 3 and 4 show an alternative embodiment of the present invention.
  • a swimming bath pool 1 with a bottom part 14 at a lower level and a bottom part 15 at a higher level.
  • the height of the bottom part 15 is adjustable. Therefore, this part 15 has floating capacity and is retained by pulling cables 17.
  • the bottom part 15 is at a lower level.
  • a bridging part or flap 13 extends between the bottom parts 14, 15. With the flap 13, it is impossible for swimmers to swim below the bottom part 15.
  • Such a flap 13, which can slide or ride with each lower edge over the bottom part 14, and is pivotally connected to the bottom part 15, is known as such from NL-A-7411696.
  • said bridging part 13 is pivotally connected to an adjustable floating body with its upper edge.
  • the bridging part 13 is an integral part with the retaining wall 3.
  • this combination of bridging part 13 and retaining wall part 3 can swing with respect to the bottom part 15 and can slide with respect to said bottom part 15 as well, viewed in the direction from the upper edge to the lower edge and vice versa.
  • the retaining wall part 3 is provided with slide guides 19, which are evenly distributed over the length of the retaining wall part 3.
  • those guides 19 have a pitch of one to four metres.
  • slots 18 are provided, which are registered with the guides 19.
  • a link 20 projects trough each slot 18.
  • a spring element 21 biasses the link 20 to its retracted position within the bottom part 15. With its end projecting from the bottom part 15, each link 20 is rotatable/swingable at 22 connected to a respective guiding element. Therefor, there is a pivotable slight connection 16 between the bottom part 15 and the retaining wall part 3. With pulling cables 24, 25, the retaining wall part 3 can be locked in its extended position (figure 3).
  • an actuating arm 23 is connected to the combination below the bottom part 15, projecting from the bridging part 13. Said arm 23 is at its free end coupled to a pulling cable 24. By pulling the pulling cable 24, the combination can be swiftled in the direction of arrow A. For return, a pulling cable 25 is connected to the bridging part 13 in the vicinity of its lower edge.
  • a structure as illustrated in figure 2 and 3 of NL-A-7411696 could be adopted to.
