Description

【０００１】
【発明の属する技術分野】
この発明に係る可動床式プール用滑り込み防止壁は、床面の一部を昇降自在な可動床とした可動床式プールにおいて、上記可動床を上昇させた状態時に、この可動床と該可動床以外の床面（例えば、固定床）との境界部に生じる隙間開口から、人や物が滑り込むことを防止するのに利用する。
【０００２】
【従来の技術】
近年、健康増進や運動能力の向上等を図るべく、スイミング或は水中での各種エクソサイズを行うことが、老若男女を問わず人気を博している。このようなスイミング等を行うためのプールには、予め所望量の水を貯留している。しかしながら、この貯留した水の深さを、例えば大人の身長に合わせた場合には、子供がスイミングや各種水中エクソサイズを行う場合に深過ぎてしまい、安全管理上、好ましいものではない。逆に、子供の身長に合わせて水深を調節した場合、大人にとっては浅過ぎて所望のエクソサイズを行えない等の不都合を伴う。
【０００３】
このような不具合を解消するためには、上記スイミング等を行う者（グループ）等の身長を勘案して、適宜水深を調節すれば良いが、水の給排水に伴う手間等が増大する等、新たな不具合が生じてしまう。
【０００４】
上述したような不具合をいずれも解消すべく、例えば図１０に示すように、プール１の中に、ジャバラ式支柱や索条或いはエアシリンダ等の流体圧シリンダを用いて昇降自在とした可動床２を設ける技術が提案され、又、実際に使用されている。このような可動床２を備えたプール１においては、身長の低い者（グループ）が使用する場合には上昇させた状態の可動床２部分（図９の下端部分）を使用し、身長の高い者が使用する場合には固定床３部分（図９の上半部）で使用する。これにより、上述したような不具合が解消される。
【０００５】
ところが、上述したような従来の可動床式のプール１においては、床面の一部を可動床２とすることに起因して、以下のような新たな不具合が生じる。すなわち、可動床２を上昇させた場合、この可動床２と上記固定床３との境界部分において、図１１に示すような開口４が生じることが避けられない。このような開口４が生じた場合、当該開口４から遊泳者やプール内に存在する物が滑り込む虞れがある。上記開口４を介して人や物が滑り込んだ場合、これに気づかないまま作業者等が可動床２を昇降（特に、下降）させると、人身事故（人が滑り込んだ場合）や物損事故（人或いは物が滑り込んだ場合）等の大事故に繋がってしまう。
【０００６】
このような事故の発生を防止するためには、図１２に示すように、上記開口４部分を塞ぐための滑り込み防止壁５を設けることが効果的であり、又、実際に実施されている。この滑り込み防止壁５は、可動床２が最大限上昇した場合の高さに合致する高さを有する壁板６の上端部を、上記可動床５の裏面に固定することで構成されている。このような滑り込み防止壁５を設置することにより、上述した事故を未然に防ぐことができる。
【０００７】
【発明が解決しようとする課題】
ところが、上述したような滑り込み防止壁５を設けた場合、新たに、以下のような不都合が生じる。すなわち、上記滑り込み防止壁５を設けた場合、図１３に示すように、この滑り込み防止壁５に対向する固定床３部分に滑り込み防止壁５を収納するための収納部７を設ける必要がある。この収納部７の深さＤは、上記滑り込み防止壁５の高さＨと同等以上としておく必要がある。このように、上記滑り込み防止壁５設置部分に対応する個所に収納部７を凹設することに伴い、可動床式プール１の製造コストが増大してしまう。しかもこの収納部７は、可動床２の上昇時にはデッドスペースとなるため、利用効率と言った面からも改善の余地がある。上記収納部７の深さＤを小さくすれば製造コストの低減を果たせるが、この場合には可動床２の昇降範囲が小さくなってしまい、却って、可動床式プール１の使い勝手が悪化してしまう。
【０００８】
この発明に係る可動床式プール用滑り込み防止壁は、上述のような不都合を解消すべく創案したもので、その目的とするところは、上記滑り込み防止壁を設けた可動床式プールを建設する際に、上記滑り込み防止壁を収納するための収納部の深さを小さく抑えることにより、製造コストを低廉化することにある。更には、上記製造コストの低減とともに、滑り込み防止機能をより確実にすることも目的とする。
【０００９】
【課題を解決するための手段】
上記目的を達成するために、この発明に係る可動床式プール用滑り込み防止壁は、請求項１に記載したように、床面の一部を昇降自在な可動床とした可動床式プールの上記可動床と該可動床以外の床との境界部に生じる隙間から、人及び／又は物が滑り込むことを防止するための可動床式プール用滑り込み防止壁であって、上下方向に亙って複数に分割された壁板と、上下方向に隣り合う各壁板の上下方向に亙る相対移動を自在とするスライド機構とを備え、上記可動床の最下降時には、上側の壁板と下側の壁板とが重畳する状態で、これら各壁板が上記プールの床面に凹設した収納部に収納自在とされ、上記可動床が該可動床以外の床よりも上昇した状態時には、上側の壁板と下側の壁板との、上記スライド機構による相対移動により、上記隙間を閉鎖自在としたことを特徴とするものである。
【００１０】
尚、上記スライド機構としては、請求項２に記載したように、上下に隣り合う各壁板のうちの一方の壁板に上下方向に亙って形成された、少なくとも一のガイド部と、上記各壁板のうちの他方の壁板に形成された、上記ガイド部に沿って移動自在な係合部と、から構成することができる。より具体的には、例えば請求項３に記載したように、前記ガイド部をあり溝とし、前記係合部を、上記あり溝に遊嵌する係合キーとすることができる。
【００１１】
又、請求項４に記載した発明は、上記請求項１に記載した発明を限定したもので、上記滑り込み防止壁を、上下方向に亙って二分割された第一、第二の壁板から構成している。そして、上記可動床の最下降時には、上記スライド機構により、上記第一の壁板と第二の壁板とが重畳する状態で、これら各壁板が上記プールの床面に凹設した収納部に収納自在とされ、上記可動床が当該可動床以外の床よりも上昇した状態時には、この可動床に連結した第一の壁板と第二の壁板との、可動床の上昇量に応じた相対移動によって上記隙間を閉鎖自在としている。
【００１２】
上記請求項４に記載した構成の場合においても、上記スライダ機構は前述した各種構成を採用できる。特に、請求項５に記載したように、前記スライド機構を、前記可動床の裏面にその一端を固定された第一の壁板の上端部にその上端を固定された、少なくとも一の鉛直ガイドと、前記第二の壁板の下端部にその下端を固定され、上記鉛直ガイドに沿って昇降自在なスライダと、から構成することができる。
【００１３】
この発明に係る可動床式プール用滑り込み防止壁は、上述のように構成されるため、滑り込み防止壁の不使用時（可動床の最下降時）には、上下に隣り合う壁板（請求項４に記載した発明の場合、第一、第二の各壁板）が重なった状態で収納部に収納される。このため、上記収納部の深さを従来構造の半分程度にできる。この結果、可動床式プールの製造コストを低減できる。尚、上記滑り込み防止壁の滑り込み防止機能を確実なものとするために、例えば各壁板を高剛性の部材により製造する。これにより、プール内の水圧やプール利用者の接触等によって滑り込み防止壁が揺れ動き、上記隙間が現れることを防止し、当該滑り込み防止機能を確実なものとできる。
【００１４】
更に、上記滑り込み防止機能をより一層確実なものとするためには、以下のように構成することが効果的である。すなわち、請求項６に記載したように、少なくとも一の壁板を少なくとも上記プールの可動床非設置部分側に向けて支承する支承部材を備えて成る滑り込み防止壁支承機構を設ける。この滑り込み防止壁支承機構としては、請求項７に記載したように、上記滑り込み防止壁支承機構を構成する支承部材を、その上端を上記可動床の下面に固定の部分に固設され、その下端に上記壁板の裏面に接触可能に設けられたローラとした構成や、請求項８に記載したように、上記滑り込み防止壁支承機構を構成する支承部材を、上下方向に隣り合う各壁板のうちの下側の壁板の上端部に設けられ、上側の壁板に向けて突出するとともに、この上側の壁板若しくはこの壁板に並設された部材に接触可能な第一のローラと、上記上側の壁板若しくはこの壁板に並設された部材の下端部に設けられ、上記上側の壁板に向けて突出するとともに、この上側の壁板に接触可能な第二のローラと、を備えた構成を採用できる。このような滑り込み防止壁支承機構を設けることにより、上記滑り込み防止機能をより一層確実なものとできる。
【００１５】
【発明の実施の形態】
以下、添付図面に示す実施の形態例に基づき、この発明を詳細に説明する。本形態例に係る可動床式プール用滑り込み防止壁は、前記図１０に示すように、床面の一部を昇降自在な可動床２とした可動床式プール１の上記可動床２と固定床３との境界部に生じる隙間開口４（図１１参照）から、人や物が滑り込むことを防止するための可動床式プール用滑り込み防止壁に関する。このような本形態例に係る可動床式プール用滑り込み防止壁においては、図１乃至図２に示すように、上記滑り込み防止壁８を、上下方向に亙って二分割された第一、第二の壁板９、１０から構成している。そして、上記可動床２の最下降時には、図１（Ａ）に示すように、次述するスライド機構１１（図２）により、上記第一の壁板９と第二の壁板１０とが重畳する状態で、これら各壁板９、１０が上記プール１の床面に凹設した収納部１２に収納自在とされる。一方、上記可動床２が固定床３よりも上昇した状態時には、図１（Ｂ）に示すように、前記可動床２に連結した第一の壁板９と上記第二の壁板１０とが、上記スライド機構１１による相対移動により、前記隙間４を閉鎖する。
【００１６】
尚、上記スライド機構１１は、図２（Ａ）に示すように、上下に隣り合う各壁板のうちの一方の壁板である第一の壁板９に上下方向に亙って形成された、１対のガイド部であるあり溝１３、１３と、他方の壁板である第二の壁板１０に形成された、上記あり溝１３、１３に遊嵌（係合）するとともにこれらあり溝１３、１３に沿って移動自在な係合部である係合キー１４、１４と、から構成することができる。但し、上記スライド機構１１としては、図２（Ｂ）、或いは後述する図４乃至図６に示すように、壁板９、１０の相対移動（昇降）を可能とするとともに、容易に離脱することのない構成であれば、他にも種々の構成のものを採用できる。上記図２に示した構成は、第一の壁板９に形成したガイド溝１５、１５と、第二の壁板１０に、上記ガイド溝１５、１５に沿う移動自在に設けられたローラ１６、１６とによって、上記スライド機構１１を構成したものである。
【００１７】
本形態例に係る可動床式プール用滑り込み防止壁８は、上述のように構成されるため、滑り込み防止壁８の不使用時（可動床の最下降時）には、この滑り込み防止壁８を、上下に隣り合う第一、第二の各壁板９、１０が重なった状態で収納部１２に収納することができる。このため、可動床２の昇降量を同じとした場合に収納部１２の深さｄを従来構造の半分程度（ｄ≒Ｄ／２）にできる。この結果、収納部１２を凹設することによるデッドスペースの増大や製造コストの低減を図れる。尚、各壁板９、１０を高剛性の部材によって製造することにより、滑り込み防止壁８の滑り込み防止機能を確実なものとすることができる。すなわち、プール１内の水圧やプール利用者の接触等によって滑り込み防止壁８が揺れ動いて、上記隙間開口４が現れることを防止し、当該滑り込み防止機能を確実なものとできる。尚、図３に示した第二形態例は、滑り込み防止壁８を構成する第一、第二の各壁板９、１０の配設状態を、上記第一形態例とは逆にしたものである。その他の構成並びに作用は、上記第一形態例と同様である。
【００１８】
【実施例】
次に、この発明を具体化した実施例について説明する。図４乃至図７は、この発明の第一実施例の構造を示している。尚、上述した各形態例と同等部分には同一符号を付して重複する説明を省略若しくは簡略化する。本実施例においては、上記滑り込み防止壁８を、上下方向に亙って二分割された第一、第二の壁板９、１０から構成している。但し、図示の構造の場合、上記滑り込み防止壁８は、それぞれ単一の壁板９、１０を図１０に示すプール１の長手方向（図１０の左右方向）に亙って設けているわけではなく、例えばその長さ寸法（横寸法）が１００cm程度のものを、上記長手方向（図１０の左右方向）に亙って複数枚ずつ（例えば２５ｍプールの場合、２５枚）設ける。そして、上記可動床２の最下降時には、図６に示すように、スライド機構１１により、上記第一の壁板９と第二の壁板１０とが重畳する状態で、上記プール１に凹設した収納部１２に収納自在としている。一方、上記可動床２が固定床３よりも上昇した状態時には、前記スライド機構１１により、図５に示すように、前記可動床２に連結した第一の壁板９と上記第二の壁板１０とが相対移動して前記隙間４を閉鎖自在としている。
【００１９】
本実施例の場合、上記スライド機構１１は、以下のように構成している。すなわち、上記可動床２の裏面にその一端（図５、図６の上端）を固定された第一の壁板９の上端（図５、図６の上端）にその上端を固定された一の鉛直ガイド２２と、前記第二の壁板１０の下端部に固定され、上記鉛直ガイド２２に外嵌して該鉛直ガイド２２に沿って昇降自在なスライダ２３と、を備えることにより構成されている。尚、上記第一、第二の各壁板９、１０のそれぞれの高さは、互いにほぼ等しくするとともに、鉛直ガイド２２の長さを適宜設定することにより、第一、第二の各壁板９、１０を、図５に示す状態と図６に示す状態との間で昇降自在としている。
【００２０】
更に、本実施例に係る可動床式プール用滑り込み防止壁８は、上記滑り込み防止機能をより一層確実なものとすべく、図５、図６に示すように、支承部材を備えた防止壁支承機構を設けている。すなわち、上端を前記可動床２の下面に固設した延出部材２６の下端に、前記第二の壁板１０の裏面（図５、図６の右面）に接触可能なローラ２５を設けている。このローラ２５は、通常の状態（第二の壁板１０に遊泳者等による力が作用していない状態で、図５、図６に示す状態）では、第二の壁板１０に接触しないが、遊泳者がキックする等によって第二の壁板１０にその表面側（図５、図６の左側）から裏面側（図５、図６の右側）に向かう力が加わった場合に、第二の壁板１０の変位に伴って両者が接触し、この力を支承する。上記ローラ２５が、特許請求の範囲に記載した支承機構を構成する支承部材である。尚、上記第一の壁板９にも遊泳者のキック等による力が加わるが、この場合、第一の壁板９が隙間開口４の閉鎖を解除されるほどに変位することは、上記スライダ２３等の存在よる剛性向上によって防止される。
【００２１】
本実施例に係る可動床式プール用滑り込み防止壁８は、上述のように構成されるため、従来構造に比較して、滑り込み防止壁８を収納するための収納部１２を従来構造の半分程度の深さにできる。すなわち、可動床２を下降させ、滑り込み防止壁８を収納部１２に収納した状態においては、図６に示すように、第一、第二の壁板９、１０が互いに重なり合った状態である。このため、上記収納部１２の深さｄを、これら互いにほぼ等しい高さを有する各壁板９、１０の高さに見合う深さｄ（≒Ｄ／２）に抑えることができる。この結果、収納部１２を設けることに伴って生じるデッドスペースの発生を抑制できるとともに、滑り込み防止壁を設けた可動床式のプールの製造コストを低減できる。
【００２２】
又、上述したように、遊泳者がキックする等によって第二の壁板１０にその表面側から裏面側に向かう力が加わった場合でも、上記支承部材であるローラ２５によって上記力を支承することができるため、耐久性の向上及び滑り込み防止機能の向上を図ることができる。
【００２３】
次に、図８乃至図９は、この発明の第二実施例を示している。本実施例の場合、支承機構を除いて、前述した第一形態例と同様に構成している。上記滑り込み防止壁支承機構は、上記第一実施例におけるローラ２５を１対設けた構造である。すなわち、前記第二の壁板１０の上端部に、前記延出部材２６に向けて突出し、この延出部材２６に接触可能な第一のローラ２７を設けるとともに、上記延出部材２６の下端部に上記第二の壁板１０に向けて突出し、この第二の壁板１０に接触可能な第二のローラ２８を設けている。このように構成すれば、滑り込み防止壁８の内外いずれの方向から力が加わった場合でも、この力を支承でき、耐久性と滑り込み防止機能とのより一層の向上を図ることができる。尚、上記延出部材２６が特許請求の範囲に記載した壁板に並設された部材に相当する。又、上記図９（Ａ）は、可動床２の最下降状態を示しているわけではなく、上昇途上若しくは下降途上の状態を示している。更に、本実施例におけるスライダ機構は、前述した形態例のごとき構成である。その他の構成並びに作用は、上述した第一実施例と同様である。
【００２４】
尚、上記防止壁支承機構は、図示のようなローラに限定されるものではなく、壁板を支承可能な部材であれば、いずれの部材でも採用できる。例えば、当該壁板に作用する外力を受けるパイプ材、板材等を壁板に接触或いは、外力の作用に伴って接触自在に設けておくことができる。或いは、上記可動床２の上昇に伴って第二の壁板１０の下端部を支持する支持部材（例えば、長尺な鉄棒材）を、第二の壁板１０の裏面下端部に送り出すようにしても良い。又、上記壁板９、１０としては、図示の例に限定されることはなく、或る程度の剛性を有し、且つ軽量化を達成できる金網等によって構成することができる。
【００２５】
【発明の効果】
この発明に係る可動床式プール用滑り込み防止壁は、上述のように構成され作用するため、滑り込み防止壁の設置に伴う収納部の設置の際に、この収納部の存在によって生じるデッドスペースを小さく抑えることができる。又、この結果、滑り込み防止壁を設けた可動床式のプールの製造コストを低廉化することができる。しかも、支承機構を付設することにより、滑り込み防止機能を従来と同等かそれ以上にすることができ、効果的な滑り込み防止壁を安価に設置可能となる。従って、危険回避に果たす役割が大きい。

BACKGROUND OF THE INVENTION
The slip-prevention wall for a movable floor pool according to the present invention is a movable floor pool in which a part of the floor surface is a movable floor that can be moved up and down, and when the movable floor is raised, the movable floor and the movable floor It is used to prevent a person or an object from slipping through a gap opening formed at a boundary portion with a floor surface other than the floor surface (for example, a fixed floor).
[0002]
[Prior art]
In recent years, swimming and underwater exercises are gaining popularity regardless of age or gender in order to improve health or improve athletic performance. A desired amount of water is stored in advance in a pool for performing such swimming. However, when the depth of the stored water is adjusted to the height of an adult, for example, it is too deep when a child performs swimming or various underwater exercises, which is not preferable in terms of safety management. On the other hand, adjusting the water depth according to the height of the child is accompanied by inconveniences such as being too shallow for an adult to perform desired exercise.
[0003]
In order to eliminate such problems, the water depth should be adjusted as appropriate in consideration of the height of the person (group) who performs the above swimming, etc. Will cause trouble.
[0004]
In order to eliminate any of the above-described problems, for example, as shown in FIG. 10, the movable floor 2 can be moved up and down by using a fluid pressure cylinder such as a bellows-type column, rope or air cylinder in a pool 1. A technique for providing the above has been proposed and is actually used. In the pool 1 provided with such a movable floor 2, when a person (group) with a short height uses it, the movable floor 2 portion in the raised state (the lower end portion in FIG. 9) is used, and the height is high. When used by a person, it is used on the fixed floor 3 (the upper half of FIG. 9). Thereby, the problems as described above are eliminated.
[0005]
However, in the conventional movable floor pool 1 as described above, the following new problems occur due to the movable floor 2 being part of the floor surface. That is, when the movable floor 2 is raised, it is inevitable that an opening 4 as shown in FIG. 11 is generated at the boundary between the movable floor 2 and the fixed floor 3. When such an opening 4 is generated, there is a possibility that an object existing in the swimmer or the pool slips from the opening 4. When a person or an object slips through the opening 4, if an operator raises or lowers (especially descends) the movable floor 2 without being aware of this, a personal injury (when a person slips) or a property damage accident (person Otherwise, it may lead to a major accident.
[0006]
In order to prevent the occurrence of such an accident, as shown in FIG. 12, it is effective to provide a slip-in prevention wall 5 for closing the opening 4 portion, and is actually implemented. The slip-in prevention wall 5 is configured by fixing an upper end portion of a wall plate 6 having a height that matches a height when the movable floor 2 is raised to the maximum to the back surface of the movable floor 5. By installing such a slip-in prevention wall 5, the above-mentioned accident can be prevented in advance.
[0007]
[Problems to be solved by the invention]
However, when the slip-in prevention wall 5 as described above is provided, the following inconvenience occurs anew. That is, when the slip-in prevention wall 5 is provided, as shown in FIG. 13, it is necessary to provide a storage portion 7 for storing the slip-in prevention wall 5 in the fixed floor 3 portion facing the slip-in prevention wall 5. The depth D of the storage portion 7 needs to be equal to or greater than the height H of the slip-in prevention wall 5. As described above, as the storage portion 7 is recessed at a location corresponding to the installation portion of the slip-in prevention wall 5, the manufacturing cost of the movable floor pool 1 increases. Moreover, since the storage portion 7 becomes a dead space when the movable floor 2 is raised, there is room for improvement in terms of utilization efficiency. If the depth D of the storage portion 7 is reduced, the manufacturing cost can be reduced. In this case, however, the ascending / descending range of the movable floor 2 is reduced, and the usability of the movable floor pool 1 is deteriorated. .
[0008]
The slip-prevention wall for a movable floor pool according to the present invention was devised to eliminate the above-described disadvantages, and the object is to construct a movable floor pool provided with the slip-prevention wall. In addition, the manufacturing cost can be reduced by suppressing the depth of the storage portion for storing the slip-in prevention wall. Furthermore, it aims at making the anti-slip | skid prevention function more reliable with the reduction of the said manufacturing cost.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the slip-preventing wall for a movable floor pool according to the present invention is the movable floor pool according to the first aspect, wherein a part of the floor surface is a movable floor that can be raised and lowered. A sliding floor for a movable floor type pool for preventing a person and / or an object from slipping from a gap generated at a boundary portion between the movable floor and a floor other than the movable floor, and a plurality of sliding walls in the vertical direction. And a slide mechanism that allows relative movement in the vertical direction of each wall plate adjacent in the vertical direction, and when the movable floor is at the lowest position, the upper wall plate and the lower wall are provided. In a state where the plates overlap each other, these wall plates can be stored in a storage portion recessed in the floor surface of the pool, and when the movable floor is raised above the floor other than the movable floor, the upper wall Due to the relative movement of the plate and the lower wall plate by the slide mechanism, It is characterized in that it has a closeable clearance.
[0010]
In addition, as the slide mechanism, as described in claim 2, at least one guide portion formed over one wall plate in the vertical direction on each wall plate adjacent to the upper and lower sides, and the above An engaging portion that is formed on the other wall plate of the wall plates and is movable along the guide portion. More specifically, for example, as described in claim 3, the guide portion can be a dovetail groove, and the engagement portion can be an engagement key loosely fitted in the dovetail groove.
[0011]
In addition, the invention described in claim 4 is a limited version of the invention described in claim 1, and the slip-preventing wall is divided into first and second wall plates that are divided into two in the vertical direction. It is composed. When the movable floor is at its lowest position, the slide mechanism causes the first wall plate and the second wall plate to overlap each other so that each wall plate is recessed in the floor of the pool. When the movable floor is raised above the floor other than the movable floor, the first floorboard and the second wallboard connected to the movable floor are in accordance with the amount of lift of the movable floor. The gap is freely closed by relative movement.
[0012]
Also in the case of the configuration described in claim 4, the slider mechanism can employ the various configurations described above. In particular, as described in claim 5, the slide mechanism includes at least one vertical guide whose upper end is fixed to an upper end portion of a first wall plate whose one end is fixed to the back surface of the movable floor. The slider has a lower end fixed to the lower end portion of the second wall plate and is movable up and down along the vertical guide.
[0013]
Since the slip-prevention wall for the movable floor pool according to the present invention is configured as described above, when the slip-prevention wall is not used (when the movable floor is at the lowest position), the wall plates adjacent to each other vertically In the case of the invention described in No. 4, the first and second wall plates) are stored in the storage portion in a state of overlapping. For this reason, the depth of the said accommodating part can be made into about half of the conventional structure. As a result, the manufacturing cost of the movable floor pool can be reduced. In order to secure the anti-slip function of the anti-slip wall, for example, each wall plate is manufactured from a highly rigid member. This prevents the slip-in prevention wall from swaying due to the water pressure in the pool, the contact of the pool user, or the like, thereby preventing the above-described gap from appearing, thereby ensuring the slip-in prevention function.
[0014]
Furthermore, in order to further ensure the slip-in prevention function, it is effective to configure as follows.

【Example】
Next, an embodiment embodying the present invention will be described. 4 to 7 show the structure of the first embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the part equivalent to each form example mentioned above, and the overlapping description is abbreviate | omitted or simplified. In this embodiment, the slip-in prevention wall 8 is composed of first and second wall plates 9 and 10 which are divided into two in the vertical direction. However, in the case of the illustrated structure, the slip-in prevention wall 8 is not provided with a single wall plate 9, 10 over the longitudinal direction of the pool 1 shown in FIG. 10 (the left-right direction in FIG. 10). For example, a plurality (for example, 25 in the case of a 25 m pool) having a length dimension (lateral dimension) of about 100 cm is provided along the longitudinal direction (left-right direction in FIG. 10). When the movable floor 2 is at the lowest position, as shown in FIG. 6, the slide mechanism 11 is recessed in the pool 1 with the first wall plate 9 and the second wall plate 10 superimposed on each other. The storage unit 12 can be stored freely. On the other hand, when the movable floor 2 is raised above the fixed floor 3, the slide mechanism 11 causes the first wall plate 9 and the second wall plate connected to the movable floor 2 as shown in FIG. 10 is relatively moved so that the gap 4 can be closed freely.
[0019]
In the case of the present embodiment, the slide mechanism 11 is configured as follows. That is, the upper end is fixed to the upper end (the upper end in FIGS. 5 and 6) of the first wall plate 9 whose one end (the upper end in FIGS. 5 and 6) is fixed to the back surface of the movable floor 2. It comprises a vertical guide 22 and a slider 23 that is fixed to the lower end of the second wall plate 10 and that is externally fitted to the vertical guide 22 and can be moved up and down along the vertical guide 22. . The first and second wall plates 9 and 10 are substantially equal in height to each other, and the length of the vertical guide 22 is set as appropriate, so that the first and second wall plates are appropriately set. 9 and 10 are movable up and down between the state shown in FIG. 5 and the state shown in FIG.

Further, the movable floor pool slip-in prevention wall 8 according to the present embodiment has a prevention wall support provided with a support member as shown in FIGS. 5 and 6 in order to further ensure the above-mentioned slip-in prevention function. A mechanism is provided. That is, the roller 25 that can contact the back surface of the second wall plate 10 (the right surface in FIGS. 5 and 6) is provided at the lower end of the extending member 26 whose upper end is fixed to the lower surface of the movable floor 2. . The roller 25 does not contact the second wall plate 10 in a normal state (the state shown in FIGS. 5 and 6 in a state in which no force is applied to the second wall plate 10 by a swimmer or the like). When a force is applied to the second wall plate 10 from the front surface side (left side in FIGS. 5 and 6) to the back surface side (right side in FIGS. 5 and 6) due to a kick by a swimmer, etc. As the wall plate 10 is displaced, both come into contact and support this force. The roller 25 is a support member constituting the support mechanism described in the claims. In addition, although the force by a swimmer's kick etc. is added also to said 1st wall board 9, in this case, the displacement of the 1st wall board 9 so that closure of the clearance opening 4 is cancelled | released is said slider It is prevented by the rigidity improvement due to the presence of 23 etc.
[0021]
The movable floor pool slip-in prevention wall 8 according to the present embodiment is configured as described above, and therefore the storage portion 12 for storing the slip-in prevention wall 8 is about half of the conventional structure compared to the conventional structure. Can be as deep as possible. That is, in a state where the movable floor 2 is lowered and the slip-in prevention wall 8 is stored in the storage portion 12, the first and second wall plates 9, 10 overlap each other as shown in FIG. For this reason, the depth d of the storage portion 12 can be suppressed to a depth d (≈D / 2) corresponding to the heights of the wall plates 9 and 10 having substantially the same height. As a result, it is possible to suppress the occurrence of dead space that accompanies the provision of the storage portion 12, and it is possible to reduce the manufacturing cost of a movable floor pool provided with a slip-in prevention wall.
[0022]
Further, as described above, even when a force is applied to the second wall plate 10 from the front surface side to the back surface side due to kicking by the swimmer, the force is supported by the roller 25 as the support member. Therefore, it is possible to improve the durability and improve the slip-in preventing function.

In the case of the present embodiment, the configuration is the same as that of the first embodiment described above except for the support mechanism. The slip-in prevention wall support mechanism has a structure in which a pair of rollers 25 in the first embodiment is provided. That is, a first roller 27 is provided at the upper end portion of the second wall plate 10 so as to project toward the extending member 26 and be in contact with the extending member 26, and the lower end portion of the extending member 26. A second roller 28 that protrudes toward the second wall plate 10 and is capable of contacting the second wall plate 10 is provided. If comprised in this way, even if force is added from the inside or outside direction of the slip-in prevention wall 8, this force can be supported, and the further improvement of durability and a slip-in prevention function can be aimed at. The extending member 26 corresponds to a member arranged in parallel with the wall plate described in the claims. Further, FIG. 9A does not show the lowest lowered state of the movable floor 2 but shows a state of rising or falling. Furthermore, the slider mechanism in the present embodiment has a configuration as in the above-described embodiment. Other configurations and operations are the same as those of the first embodiment described above.
[0024]
