Description

  The present invention relates to an amusement pool that is used by filling a square cylindrical wall standing on the peripheral edge of a bottom plate with air.

  As a playground equipment for allowing children to play with water casually, an air-injected simple play pool has existed for a long time, and has been used in places such as the yard of a house or a schoolyard of a kindergarten. As a general type of such a pool for play, a side wall is provided on the periphery of the bottom sheet as shown in Patent Documents 1 and 2, and the side wall is formed into a donut shape, that is, an internal hollow cylindrical bag. Those formed and stacked in a plurality of stages are widely used.

  However, in the game pools shown in Patent Documents 1 and 2, air supply / exhaust ports are provided in each of the cylindrical bags stacked in a plurality of stages, and air must be injected and discharged for each bag. Therefore, there is an inconvenience that it takes time and effort to use and clean up. Incidentally, in order to avoid the above-mentioned inconvenience, it is conceivable to form the side wall portion of the game pool with one cylindrical bag, but in this case, another new problem occurs. That is, in order to make the water stored in the pool for play into a depth that a child can enjoy normally, and to withstand the water pressure of the stored water, it is necessary to make the side wall part a certain size. Along with this, the diameter dimension of the side wall part must be lengthened. However, such a cylindrical side wall portion has a long diameter portion, and the center portion in the height direction corresponding to the diameter portion has an arc shape bulging most outward. It will be very difficult to get over the side wall by itself. For this reason, the side wall of the play pool is desired to have a rectangular parallelepiped shape with a rectangular side surface.

  However, if a rectangular parallelepiped side wall is simply formed with a relatively soft synthetic resin sheet, when the internal pressure increases when air is injected, the outer wall and the inner wall gradually expand outward in an arc shape. In the end, the side wall cannot be maintained in a rectangular parallelepiped shape.

  Therefore, the invention disclosed in Patent Document 3 can be applied as a technique for solving such a problem. In other words, the present invention relates to an air cell of an air mat. The ends of the upper sheet 18 and the lower sheet 19 that form the wall of the air cell body 2 are welded at the center in the height direction of the air cell body 2, Each end of the suspension 22 is welded together at the joint of a sheet. And since this suspension 22 is horizontally extended in the height direction center part on the inner surface of the outer wall and the inner wall of the air cell body 2, when the air cell body 2 is filled with air, the suspension 22 is stretched. The thickness of the air cell body 2 can be maintained at the length of the suspension 22. In this respect, certainly, if the technique disclosed in Patent Document 3 is diverted to the side wall of the play pool, both sides of the side wall of the play pool are prevented from bulging in an arc shape, and the side wall is substantially rectangular. It may be possible to maintain the shape.

  However, when this technology is diverted to the side walls of the game pool, the following another problem occurs. That is, when the side wall is expanded by air, the suspension is pulled with a considerable force in the horizontal direction by the internal pressure of the side wall. At this time, like the suspension shown in Patent Document 3, if it is welded to the joint portion of the sheet forming the cell body, the tension is concentrated on the joint portion. May be broken. In particular, in the case of a game pool, water is stored inside, so that it is affected by water pressure, and moreover, since a player hits a side wall or puts a hand on it, a human pressure is applied.

  Therefore, in view of the above problems, the present invention maintains the cross-sectional shape in a substantially rectangular shape by the shape-retaining member even if the inside of the rectangular cylindrical wall that is the side wall portion of the game pool is filled with air, An object of the present invention is to provide a game pool in which the rectangular cylindrical wall is not easily damaged by the pressure in the cylindrical wall or the tension of the shape holding member.

  In order to achieve this object, the present invention provides an amusement pool in which an internal hollow rectangular tube wall is provided on the periphery of a bottom plate, and the rectangular tube wall is filled with air. The square cylindrical wall is provided with a mounting seat opposed to each other in the center in the height direction of each of the inner surface of the outer wall and the inner wall that forms the wall, and a shape holding member is bridged between the mounting seats of the outer wall and the inner wall. When the inside is filled with air, the shape holding member is stretched so that the cross section of the rectangular tubular wall is held in a substantially rectangular shape. Note that the term “cuboid” here means “substantially rectangular parallelepiped”, and includes those in which each surface constituting the rectangular parallelepiped is a little arc.

  The mounting seat according to claim 1 includes a horizontally long belt-like base plate portion having a predetermined width, and an upright plate portion extending in a vertical direction of the base plate portion at a center in the width direction of the base plate portion. The base plate portion is bonded to the inner surface of the rectangular tubular wall, and the shape holding member is attached to the upright plate portion.

  Furthermore, the mounting seat according to claim 2 is configured such that the seal portion is the standing plate portion by overlapping both ends in the width direction of the horizontally long rectangular belt-like member and sealing each other, and the portion other than the standing plate portion The one side of the folded part is used as the base plate part, and the other side is used as a sticking plate part for the belt-like sheet.

  In the game pool according to the present invention, it is desirable that a cylindrical drainage passage formed so as to penetrate between the outer wall and the inner wall at the lower end of the square cylindrical wall.

  The pool for play according to the present invention has a cross-section of the rectangular tubular wall substantially reduced by a shape holding member spanned in the rectangular tubular wall when the inside of the rectangular tubular wall serving as the side wall portion is filled with air. It can be held in a rectangular shape. In addition, since the shape holding member is attached to the square cylindrical wall via the mounting seat, the influence of the square cylindrical wall on the shape holding member is reduced, and the water pressure and the external pressure applied to the square cylindrical wall are reduced. The influence is also reduced, and as a result, the rectangular tubular wall is less likely to be damaged.

  Hereinafter, an embodiment of a game pool according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a game pool, and FIG. 2 is a plan view showing a part of the game pool in a cutaway manner. As shown in these drawings, the game pool of the present embodiment includes a bottom plate 1, an internal hollow rectangular tube wall 2 standing on the periphery of the bottom plate 1, and an interior of the rectangular tube wall 2. And a shape-retaining member 4 that is attached via an attachment seat 3.

  The said baseplate 1 is a member which comprises the bottom face of the pool for play, and is formed with the rectangular-shaped thermoplastic resin sheet. Specifically, the bottom plate 1 is formed by forming a foamable vinyl chloride sheet having a thickness of 9 mm into a rectangle having a size of 4300 mm × 3000 mm. Furthermore, the upper surface of the bottom plate 1 is formed on a rough surface with fine irregularities. In this way, the bottom plate 1 has a relatively thick 9 mm as a sheet, and since a foamed vinyl chloride resin excellent in flexibility is selected as the material, the bottom plate 1 plays in the play pool. It is possible to reduce the burden on the legs of the player. Moreover, even if there is a foreign substance such as a stone below the bottom plate 1, the material of the bottom plate 1 functions as a cushion and absorbs the foreign object feeling, so that the discomfort given to the player can be minimized. Furthermore, since the upper surface of the bottom plate 1 is rough, it is possible to prevent a player from accidentally sliding in the game pool. A drain port 6 is formed at one corner of the bottom plate 1.

  The said square cylindrical wall 2 is a member which surrounds the baseplate 1 and comprises the wall of a play pool, and is formed so that an inside can be filled with a thermoplastic resin sheet as a square cylindrical bag. . Further, the bottom surface of the rectangular tubular wall 2 is heat-welded to the upper surface of the peripheral edge of the bottom plate 1, thereby forming a water storage portion 7 capable of storing water inside the bottom plate 1 and the rectangular tubular wall 2. doing. Here, the structure of the rectangular tube-like wall 2 will be further described. The rectangular tube-like wall 2 is formed in a rectangular tube shape by heat-welding a 9-mm-thick vinyl chloride sheet at various places. Specifically, as shown in FIGS. 3 and 4, an outer wall sheet 8 a disposed on the outer side of the square tubular wall 2, an inner wall sheet 8 b disposed on the inner side, and an upper sheet 8 c that closes the upper part. In addition, the end portions of the lower sheet 8d that close the lower surface are connected to each other by heat welding 9a, 9b, 9c, 9d to form a substantially rectangular parallelepiped shape. In addition, this square cylindrical wall 2 is formed in a size in which the inner method of the outer wall sheet 8a and the inner wall sheet 8b is 500 mm and the height is 350 mm. Further, the rectangular tubular wall 2 is bent at substantially right angles at the four corners of the bottom plate 1 in accordance with the shape of the bottom plate 1, and has a rectangular frame shape in plan view. In addition, the square cylindrical wall 2 is formed into a rectangular shape in plan view, and the inside is a single communication-like air chamber. Therefore, if air is filled from one place, the whole is filled with air. It will be. Further, four corners of the rectangular tube-shaped wall 2, that is, portions where the respective portions 2a, 2b, 2c, 2d constituting the rectangular tube-shaped wall 2 are adjacent to each other are provided with strip-shaped seal sheets 10a, 10b, 10c and 10d are welded to reinforce the corners of the square cylindrical wall 2. Further, the welding position of each sheet has a four-layer structure. That is, at the joint portion of adjacent sheets, two narrow strip-shaped sealing members 11a and 11b are welded to the outer side surface, and one narrow strip-shaped sealing member 11c is welded to the inner side surface and adjacent to each other. The sheets to be connected are connected. Thereby, the connection between the sheets is strengthened, and even if the square tubular wall 2 receives a strong impact, the joint portion of each sheet is difficult to break.

  At the lower end of the edge portion of the rectangular tubular wall 2d, two air supply / exhaust ports 13 and 14 to which an air pump can be attached and one safety release valve 15 for suppressing excessive air intake are provided. . Incidentally, here, two air supply / exhaust ports 13 and 14 are provided. This is because when one of the air supply / exhaust ports fails, the other air supply / exhaust port can be used preliminarily. Is taken into consideration. Further, as a function of the safety release valve 15, when air is injected into the rectangular tubular wall 2, if the internal pressure reaches 14.8 kpa, the safety release valve 15 is automatically opened. The structure allows air to escape. Thereby, inconveniences such as excessive supply of air into the rectangular tubular wall 2 to burst the rectangular tubular wall 2 are eliminated. A cover 16 made of the same material as the seat forming the rectangular tubular wall 2 is mounted in front of the air supply / exhaust ports 13 and 14 and the safety release valve 15. Specifically, the cover 16 is made of a rectangular sheet material of a size that can conceal the air supply / exhaust ports 13 and 14 and the safety release valve 15, and the upper end of the back surface of the cover 16 is thermally welded to the square cylindrical wall 2d. Yes. The cover 16 can be rotated forward from this heat welded portion. Further, a laterally U-shaped hook-and-loop tape 17a is attached to the peripheral edge portion of the back surface of the cover 16, and a hook-and-loop fastener tape 17b is attached to the outer surface of the square tubular wall 2d. The surface fastener tape 17a of the cover 16 and the surface fastener tape 17b of the square tubular wall 2d are matched to conceal the air supply / exhaust ports 13 and 14 and the safety release valve 15. On the other hand, when air is supplied to or discharged from the rectangular tubular wall 2, the air supply and exhaust ports 13, 14 can be used by releasing the cover 16 from the hook-and-loop fastener tape 17b and opening it forward. Further, a drainage passage 18 used for draining water stored in the game pool is provided at the lower end of the corner of the rectangular tube-like wall 2b. As shown in FIGS. 3 and 4, the drainage passage 18 is formed in a cylindrical shape penetrating between the outer wall sheet 8 a and the inner wall sheet 8 b of the square tubular wall 2. A plug 19 is engaged with each of the opening portions at both ends of the discharge passage 18. Incidentally, since the drainage passage 18 is formed of a soft synthetic resin material, the drainage passage 18 is also folded together when the air pool is drawn out and folded. Therefore, the drainage passage 18 does not get in the way when the play pool is stored. A plurality of handles 20, 20... Used for transporting the game pool are provided at appropriate positions on the outer side surface of the rectangular tubular wall 2.

  The attachment seat 3 is for mounting a shape holding member 4 to be described later, and is opposed to the center in the height direction of each of the inner surface of the outer wall sheet 8a and the inner surface of the inner wall sheet 8b forming the square tubular wall 2. Is arranged. Further, the attachment seat 3 is provided in a circular shape so as to make a round around each of the inner surface of the outer wall sheet 8a and the inner surface of the inner wall sheet 8b. Here, the attachment seat 3A shown in FIG. 3 is the first embodiment, and the attachment seat 3A is formed of a vinyl chloride resin sheet having a transverse T-shape in cross section. That is, the mounting seat 3 </ b> A is formed by a base plate portion 25 made of a horizontally long belt plate, and an upright plate portion 26 extending in the vertical direction of the base plate portion 25 at the center in the width direction of the base plate portion 25. Yes. Then, the base plate portion 25 of the attachment seat 3A is thermally welded (adhered) to the inner surfaces of the outer wall sheet 8a and the inner wall sheet 8b of the rectangular tube-like wall 2, thereby the attachment seat 3A welded to the outer wall sheet 8a. The upright plate portion 26 and the upright plate portion 26 of the attachment seat 3A welded to the inner wall sheet 8b are in a state of facing each other. On the other hand, the mounting seat 3B shown in FIG. 4 is the second embodiment, and this mounting seat 3B is also formed of a horizontally long strip as in the first embodiment. However, this band plate is formed of a band plate whose dimension in the width direction is longer than that of the band plate serving as the base plate portion 25 of the mounting seat 3A of the first embodiment. Then, this band plate is heat-welded (sealed) with the both ends in the width direction being overlapped with each other by a predetermined dimension, and the band plate is once formed into a ring shape having a cross-sectional shape (FIG. 5A). Incidentally, the heat-welded portion of the band plate is the upright plate portion 26 of the attachment seat 3B. After that, the respective portions on both sides of the upright plate portion 26, which is a welded portion of the ring-shaped band plate, are bent and folded (FIG. 5B). And the side in which the standing board part 26 does not exist becomes the base board part 25 heat-welded (adhered) to the inner surface of the square cylindrical wall 2 among the folded parts. That is, the base plate portion 25 is welded to the inner surfaces of the outer wall sheet 8a and the inner wall sheet 8b of the square tubular wall 2 so that the mounting seat 3B is attached to the inside of the square tubular wall 2 in an opposing manner. Become. On the other hand, of the folded portions, the side where the upright plate portion 26 exists is a sticking plate portion 27 of the seal member 29. That is, although the sticking plate part 27 exists on both sides of the upright plate part 26, a seal made of a horizontally long strip extending over both the sticking plate part 27 on both sides and the inner surface of the outer wall sheet 8a or the inner surface of the inner wall sheet 8b. It is welded by the members 29 and 29. Thereby, the standing plate part 26 of the attachment seat 3B welded to the outer wall sheet 8a and the standing plate part 26 of the attachment seat 3B welded to the inner wall sheet 8b are in a state of facing each other.

  The shape holding member 4 is a horizontally long belt-like sheet made of a strong synthetic fiber fabric, and the dimension in the width direction of the mounting seats 3 and 3 facing each other in the inner wall sheet 8b and the outer wall sheet 8a. It is formed slightly longer than the inner method between the tips of the upright plate portions 26 and 26. Then, after each of the both ends in the width direction of the shape maintaining member 4 is slightly bent, the bent end portions are sewn to the upright plate portions 26 and 26 of the seats 3 and 3. Further, the shape holding member 4 is disposed in each of the portions 2a, 2b, 2c, 2d constituting the rectangular tube-shaped wall 2, and the shape holding members 4 adjacent to each other at the corners of the rectangular tube-shaped wall 2 are arranged. It is sewn with overlapping ends. Thereby, the inside of the rectangular tube-shaped wall 2 is divided into two vertically by the shape holding member 4. However, since the shape retaining member 4 has a plurality of through holes 30, 30..., When air is injected into the square tubular wall 2, the air is entirely inside the square tubular wall 2. Will be spread out. When air fills the inside of the square tubular wall 2, the shape retaining member 4 is stretched and the interval between the outer wall sheet 8a and the inner wall sheet 8b of the square tubular wall 2 is increased by a certain amount or more. It is regulated so that it does not come off, and finally the cross-sectional shape of the rectangular tubular wall 2 is held in a substantially rectangular shape.

  Next, a method of using the game pool according to the present embodiment configured as described above will be described. When not in use, the pool for play is usually stored in a folded state with its rectangular tube wall 2 being evacuated. And when using a pool for play, after expanding the folded pool for play in a flat place, the cover 16 of the rectangular tube-shaped wall 2 is opened, and either of the air supply / exhaust ports 13 and 14 is used. Air is supplied into the square tubular wall 2 using an air pump. When the square tubular wall 2 expands with this supply, the shape retaining member 4 is gradually pulled in the horizontal direction in the square tubular wall 2, and finally in the square tubular wall 2. It will be kept taut. Thereby, it can prevent that the center part of the height direction of the outer wall sheet | seat 8a and the inner wall sheet | seat 8b of the square cylindrical wall 2 bulges outside in circular arc shape, and, by extension, the cross-sectional shape of the square cylindrical wall 2 is made. It can be held in a substantially rectangular shape. At this time, the shape holding member 4 is mounted in the rectangular tube-like wall 2 via the attachment seat 3, and the base plate portion 25 of the attachment seat 3 directly heats the inner surface of the square tube-like wall 2. Since it is welded, the load due to the tension of the shape holding member 4 is reduced with respect to the sheet forming the square cylindrical wall 2, and as a result, the square cylindrical wall 2 is prevented from being damaged. In particular, in the case of the attachment seat 3 </ b> B shown in FIG. 4, the base plate portion 25 is not only welded to the inner surface of the rectangular tube-shaped wall 2, but is also sealed to both the sticking plate portion 27 and the inner surface of the rectangular tube-shaped wall 2. Since the members 29 and 29 are welded, the tension of the shape maintaining member 4 can be received more firmly. Furthermore, the part which both the base board part 25 and the sticking board part 27 of the attachment seat 3B are facing is not welded. Therefore, as shown in FIG. 4, in the state where the shape holding member 4 is tight, the base plate portion 25 and the sticking plate portion 27 are separated so as to release the strong tension of the shape holding member 4. To do. Therefore, according to the attachment seat 3B, the burden due to the tension of the shape holding member 4 can be further reduced. After filling the square tubular wall 2 with air so that the play pool can be used, water is poured into the water storage section 7 surrounded by the bottom plate 1 and the square tubular wall 2. At this time, the water depth is determined according to the age of the player, etc., but as a guideline, it is preferably 20 cm for a 1-year-old child, 25 cm for a 2-year-old child, and 30-35 cm for a 3-year-old child or older. Although not shown, since lines indicating the water depth are printed at two locations on the inner wall sheet 8b of the square tubular wall 2, it is possible to confirm whether or not an appropriate water depth has been reached according to these lines. Then, when the play in the play pool is finished and drained from the play pool, the drainage port 6 formed in the bottom plate 1 and the drainage passage 18 formed in the lower end of the rectangular tubular wall 2b. Is used. Among these, the drain port 6 of the bottom plate 1 can be drained by removing the plug capped with the drain port 6. On the other hand, the drainage passage 18 formed in the rectangular tubular wall 2 can be drained by removing the plug 19 capped at the opening and connecting a drainage hose thereto. Thus, since the drainage point is provided in two places, the drainage port 6 and the drainage channel 18, in the play pool, the drainage can be drained very efficiently. When the drainage in the game pool is finished, the air filled in the rectangular tube-like wall 2 is removed. This is automatic if the pins formed in the air supply / exhaust ports 13 and 14 are rotated. Will be exhausted. When the air in the rectangular tube-like wall 2 is completely removed, the game pool is folded to an appropriate size, and the folded game pool is rolled up and fastened with a band or the like to be stored compactly. be able to.
