Description

本発明は水上遊具に関し、詳しくは水難を防止する浮上誘導部を備えた水上遊具に関する。 The present invention relates to a water playset, and more particularly to a water playset provided with a floating guide portion for preventing a water accident.

近年、プールや海の水面に浮かぶ水上アスレチックまたは海上ウォーターパーク等と呼ばれる施設が人気となっている。これらの施設は、空気が封入される袋状のマットやスライダー等の遊具をいくつも組み合わせて水面に浮かべ、組み合わせた遊具の上を歩行することや走ることができ、さらに遊具からプールや海に飛び込むことも可能な施設である。これらの組み合わせた遊具の多くはポリ塩化ビニール等で製造され、空気が封入されている。 In recent years, facilities called floating athletics or marine water parks that float on the surface of pools and the sea have become popular. These facilities allow you to float on the surface of the water by combining a number of playsets such as bag-shaped mats and sliders that are filled with air, and you can walk or run on the combined playsets, and from the playsets to the pool or the sea. It is a facility where you can jump in. Most of these combined playsets are made of polyvinyl chloride or the like and are sealed with air.

図８は、下面が平面となっている従来の水上遊具の斜視図である。これは、ビーチマットまたはベッドのマットレスのような略直方体の形状で、このような遊具をつなぎ、また他の遊具と組み合わせて水面に浮かべ、この水上遊具の上を歩いたり、また走ったりすることができる遊具である。 FIG. 8 is a perspective view of a conventional water playset having a flat lower surface. This is a roughly rectangular parallelepiped shape, such as a beach mat or bed mattress, which connects such playsets and floats on the surface of the water in combination with other playsets to walk or run on this water playset. It is a playset that can be played.

この水面に浮かべる遊具は透明でないことが多く遊具の下側に人が潜り込んだ場合は容易に確認できないことや、遊具の下面はほぼ水平になっているためライフジャケットを着用しているとその浮力により遊具の下面に押し付けられ、泳いでも水面上に出ることが難しい場合がある。そのため、水上遊具の下面が水平になっていると水難事故につながる可能性がある。 The playset that floats on the surface of the water is often not transparent, and it is not easy to check if a person sneaks under the playset, and the underside of the playset is almost horizontal, so if you wear a life jacket, its buoyancy It may be pressed against the underside of the playset, making it difficult to get out of the water even when swimming. Therefore, if the lower surface of the water playset is horizontal, it may lead to a water accident.

特許文献１の図７には、水難事故の可能性を防止するため水上浮遊遊具に安全ネットを取り付けた図が開示されている。この安全ネットを取付けることにより、浮遊する水上浮遊遊具の下側に潜り込み水平なシートに妨げられて水面上に浮上できないで溺れるという事故を防止できるとしている。 FIG. 7 of Patent Document 1 discloses a diagram in which a safety net is attached to a floating playset on the water in order to prevent the possibility of a water accident. By installing this safety net, it is possible to prevent an accident in which the player sneaks under the floating water-floating playset and is obstructed by a horizontal sheet and cannot ascend to the surface of the water and drowns.

登録実用新案第３００９９６５号公報Registered Utility Model No. 3099665

しかし、特許文献１の図７に開示された安全ネットは、水上遊具の安全装置としては有効であるが、この安全ネットは構造が複雑で重量も重く水上遊具の下側に設置すると、安全ネットの自重で水上遊具が沈んでしまうという課題がある。 However, the safety net disclosed in FIG. 7 of Patent Document 1 is effective as a safety device for water play equipment, but this safety net has a complicated structure and is heavy, and when installed under the water play set, it is a safety net. There is a problem that the water playset sinks due to its own weight.

本発明は、上記の課題を解決するために、水上遊具の下面が凸部になるように構成し、その凸部に流体、すなわち空気や水が封入または充填されることで、水上遊具の下側に人が潜った場合にも、水上遊具下面の凸部により容易に水面上に出ることができる水上遊具である。 In order to solve the above-mentioned problems, the present invention is configured so that the lower surface of the water playset has a convex portion, and the convex portion is filled or filled with a fluid, that is, air or water, thereby under the water playset. It is a water playset that can easily come out on the water surface by the convex portion on the lower surface of the water playset even when a person dives to the side.

すなわち、柔軟な材料の薄膜で形成された密閉可能な空間の内部に流体が封入および／または充填されて水面に浮かべる水上遊具であって、その水上遊具は下面に凸部を設け、流体である空気が封入される水上遊具上部の水上浮遊部と、流体である水が充填される水上遊具下部の凸部を含む浮上誘導部とを備え、水上浮遊部と浮上誘導部との間に流体を遮断する仕切りを設けたことを特徴とする水上遊具である。
このように水上遊具の下面に凸部を設けることで、水上遊具の下側に人が潜っても容易に水面上に浮上することができる。また、仕切りを設けることで、浮上誘導部に充填された水の動きを抑え、水上遊具の安定化を図ることができる。 That is, it is a water playset in which a fluid is sealed and / or filled in a sealable space formed of a thin film of a flexible material and floats on the water surface, and the water playset is a fluid having a convex portion on the lower surface. It is provided with a floating portion on the upper part of the floating playset in which air is sealed and a floating guiding portion including a convex portion on the lower part of the floating playing equipment filled with water, which is a fluid, and a fluid is introduced between the floating portion on the water and the floating guiding portion. It is a water playset characterized by having a partition to block it.
By providing the convex portion on the lower surface of the water playset in this way, even if a person dives under the water playset, it can easily float on the water surface. Further, by providing the partition, it is possible to suppress the movement of the water filled in the floating guide portion and stabilize the water playset.

また、浮上誘導部の凸部の形状は略円弧柱形状であることを特徴とする。このように構成することで、水上遊具の下面の凸部は、その中央部より水面上へ傾斜しているため、浮力により、容易に水面上へ浮かびあがることができる。 Further, the shape of the convex portion of the levitation guide portion is characterized in that it has a substantially arcuate column shape. With this configuration, the convex portion on the lower surface of the water playset is inclined above the water surface from the central portion thereof, so that the convex portion can easily float on the water surface due to buoyancy.

また、浮上誘導部の凸部の形状は三角柱形状であることを特徴とする。このように構成することで、水上遊具の下面の凸部は、その中央部より水面上へ傾斜しているため、浮力により、容易に水面上へ浮かびあがることができる。 Further, the shape of the convex portion of the levitation guide portion is a triangular prism shape. With this configuration, the convex portion on the lower surface of the water playset is inclined above the water surface from the central portion thereof, so that the convex portion can easily float on the water surface due to buoyancy.

さらに、本発明は、水上遊具の水上浮遊部と浮上誘導部とを分離して形成し、空気が封入される水上浮遊部の下面に水が充填される浮上誘導部を取り付けることを特徴とする。
水上遊具の上部と下部が分離できるので、水上浮遊部を組立てた後、下部の浮上誘導部を取付けることができ、また取り外して水上遊具の水上浮遊部のみで使用することもできる。 Further, the present invention is characterized in that the floating portion on the water and the floating guiding portion of the floating play device are separately formed, and the floating guiding portion filled with water is attached to the lower surface of the floating portion on the water in which air is sealed. ..
Since the upper part and the lower part of the water playset can be separated, the floating guide part at the lower part can be attached after assembling the floating part on the water, or can be removed and used only on the floating part on the water.

また、水上浮遊部と浮上誘導部の周辺に複数のハトメを設け、水上浮遊部と浮上誘導部とに設けられた上下のハトメ同士をロープで結び密着させたことを特徴とする。
このように構成することにより、水上浮遊部と浮上誘導部を別々に製造することができ、空気または水が封入および／または充填された後両者をしっかりと密着させることができる。 Further, a plurality of eyelets are provided around the floating portion on the water and the floating guiding portion, and the upper and lower eyelets provided on the floating portion on the water and the floating guiding portion are tied with a rope and brought into close contact with each other.
With such a configuration, the floating portion on the water and the floating guiding portion can be manufactured separately, and after the air or water is filled and / or filled, the two can be firmly brought into close contact with each other.

また、水上遊具の浮上誘導部下部には水を充填し、浮上誘導部上部には空気を封入して空気層を設けたことを特徴とする。
空気層を設けたことにより、浮上誘導部の重量分だけ浮力を発生させることができ、浮上誘導部の重量により水上浮遊部が沈むことを防止できる。 Further, the lower part of the floating guide portion of the water play device is filled with water, and the upper portion of the floating guide portion is filled with air to provide an air layer.
By providing the air layer, buoyancy can be generated by the weight of the levitation guiding portion, and it is possible to prevent the floating portion on the water from sinking due to the weight of the levitation guiding portion.

また、水上遊具の浮上誘導部に凸部を設け、水上浮遊部と浮上誘導部との間には仕切り膜を設けないことを特徴とする。
このように構成することにより仕切りの材料を抑制することができる。 Further, the floating guide portion of the water play device is provided with a convex portion, and a partition film is not provided between the floating guide portion and the floating guide portion.
With such a configuration, the material of the partition can be suppressed.

以上、本発明によれば、水上遊具の下側に人が潜った場合でも、水上遊具の下面が凸部により傾斜しているため、容易に水面上に浮かびあがることができる。また、浮上誘導部の重量により水上浮遊部が沈むことを防ぐことができる。 As described above, according to the present invention, even when a person dives under the water playset, the lower surface of the water playset is inclined by the convex portion, so that the water playset can be easily floated on the water surface. In addition, it is possible to prevent the floating portion on the water from sinking due to the weight of the floating guiding portion.

本発明の実施形態に係る浮上誘導部に凸部を備えた水上遊具について図面を参照して説明する。 A water playset having a convex portion on a floating guide portion according to an embodiment of the present invention will be described with reference to the drawings.

図１は、本発明の実施形態に係る水上浮遊部と浮上誘導部とを備えた水上遊具を下方から見た斜視図である。図１に示す水上遊具１の水上浮遊部２は、ベッドのマットレスのような略直方体の形状であり、柔軟な材料の薄膜で形成された密閉可能な空間の内部に空気が封入されて水面に浮かべる部分である。水上遊具１の下部には浮上誘導部３が設けられ、その浮上誘導部３には凸部４が設けられている。 FIG. 1 is a perspective view of a water playset including a floating portion on the water and a floating guiding portion according to an embodiment of the present invention as viewed from below. The floating portion 2 on the water of the water playset 1 shown in FIG. 1 has a substantially rectangular parallelepiped shape like a bed mattress, and air is sealed inside a sealable space formed of a thin film of a flexible material to be placed on the water surface. It is a floating part. A levitation guide portion 3 is provided at the lower portion of the water play device 1, and a convex portion 4 is provided at the levitation guide portion 3.

浮上誘導部３は、水上浮遊部２と同じ材料で形成され、人が水上遊具１の下側に潜ったとき、人の浮力または救命胴衣の浮力により、凸部４の傾斜に沿って水面上に誘導させる部分である。水中外皮５は、浮上誘導部３の表面の水中部分の薄膜である。また、浮上誘導部３に流体注入／排出口８が複数設けられている。この流体注入／排出口８から空気または水が封入／充填され、排出される。なお、水上浮遊部２の流体注入／排出口は図示していない（以下の図も同じ）。
図１に示す浮上誘導部３の凸部４は略円弧柱形状であって、この水上遊具１と他の水平遊具を組み合わせて水上アスレチックまたは海上ウォーターパークと呼ばれる施設を構成する。 The levitation guide portion 3 is made of the same material as the water levitation portion 2, and when a person dives under the water playset 1, the buoyancy of the person or the buoyancy of the life jacket is on the water surface along the inclination of the convex portion 4. It is the part that induces to. The underwater exodermis 5 is a thin film of the underwater portion of the surface of the levitation guiding portion 3. Further, the levitation guide portion 3 is provided with a plurality of fluid injection / discharge ports 8. Air or water is sealed / filled and discharged from the fluid injection / discharge port 8. The fluid injection / discharge port of the floating portion 2 on the water is not shown (the same applies to the following figure).
The convex portion 4 of the levitation guiding portion 3 shown in FIG. 1 has a substantially arcuate column shape, and the floating playset 1 and other horizontal playsets are combined to form a facility called a floating athletic or a marine water park.

図１に示す略直方体の水上浮遊部２の他、水上遊具の平面が円形その他の形状であってもよいし、水上遊具の水上面６が水平で歩くようになっている形状のほか、滑り台を備えた遊具、梯子のような遊具、水上面６に山のような凸部を備えた水上遊具等であってもよい。これらの水上遊具の薄膜は、柔軟で流体を遮断する材料であればよく、例えばポリ塩化ビニール等により形成されている。 In addition to the substantially rectangular parallelepiped floating portion 2 on the water shown in FIG. 1, the plane of the water playset may have a circular shape or other shape, the water surface 6 of the water playset may have a shape such that it walks horizontally, and a slide. It may be a playset provided with, a playset such as a ladder, a water playset having a convex portion like a mountain on the water surface 6, and the like. The thin film of these water playsets may be any material that is flexible and blocks fluid, and is formed of, for example, polyvinyl chloride.

水上遊具の水上面６がどのような形状であってもその下面には凸部を形成し、その凸部に水が充填される。水が充填されることによって、下面の凸部は浮力を生じることなく、水上浮遊部２は浮上誘導部３の凸部４が備わっていない状態のように水面に浮かべることができる。 Regardless of the shape of the water upper surface 6 of the water playset, a convex portion is formed on the lower surface thereof, and the convex portion is filled with water. By filling with water, the convex portion on the lower surface does not generate buoyancy, and the floating portion 2 on the water can float on the water surface as if the convex portion 4 of the floating guiding portion 3 is not provided.

なお、水上遊具１の下部に浮上誘導部３を備えたことにより、その重さで上部の水上浮遊部２が沈む場合、下部の浮上誘導部３に全部水を充填しないで、浮上誘導部３の重さ分の浮力が発生するように空気を封入し浮上誘導部３の上部を空気層７としてもよい。
また、上部の水上浮遊部２と下部の浮上誘導部３との間には後述の図３等に示す仕切り９が形成されている。この仕切り９によって、上部の空気および下部の水が移動することなく遮断されるため、水上遊具１が安定化する。 If the floating guide portion 3 is provided in the lower part of the water play device 1 and the upper floating guide portion 2 sinks due to its weight, the lower floating guide portion 3 is not completely filled with water, and the floating guide portion 3 is not filled. Air may be sealed so that the buoyancy corresponding to the weight of the buoyancy is generated, and the upper part of the levitation guide portion 3 may be an air layer 7.
Further, a partition 9 as shown in FIG. 3 or the like, which will be described later, is formed between the upper floating portion 2 on the water and the lower floating guiding portion 3. Since the upper air and the lower water are blocked by the partition 9 without moving, the water playset 1 is stabilized.

通常、これらの水上浮遊部２、浮上誘導部３および仕切り９は一体として製造されるが、水上浮遊部２と浮上誘導部３との仕切り９はなくても構わない。
さらに、水上浮遊部２と浮上誘導部３は別個に分離して製造され、それぞれに空気または水が封入および／または充填された後、水上浮遊部２と浮上誘導部３が組み合わされる形態でもよい。 Normally, the floating portion 2, the floating guiding portion 3, and the partition 9 are manufactured as an integral body, but the partition 9 between the floating portion 2 on the water and the floating guiding portion 3 may not be provided.
Further, the floating portion 2 and the floating guiding portion 3 may be manufactured separately, and the floating guiding portion 2 and the floating guiding portion 3 may be combined after each of them is filled with air or water. ..

図２は、図１に示す水上遊具１の平面図であり、略長方形の形状である。この平面図には、Ａ―Ａ線およびＢ−Ｂ線の切断線があり、図３は図２に示すＡ−Ａ線による断面図であり、図４は図２に示すＢ−Ｂ線による断面図である。図４の断面図は、円弧柱の母線に沿った切断面であるため、その形状は略長方形である。 FIG. 2 is a plan view of the water playset 1 shown in FIG. 1, and has a substantially rectangular shape. In this plan view, there are cutting lines of lines AA and BB, FIG. 3 is a cross-sectional view taken along line AA shown in FIG. 2, and FIG. 4 is taken along line BB shown in FIG. It is a cross-sectional view. Since the cross-sectional view of FIG. 4 is a cut surface along the generatrix of the arc column, its shape is substantially rectangular.

図３に示す切断面は、水面の下方に向かって凸部４が形成されており、その形状は円弧形状である。仮に人が水上遊具１の下側に潜った場合、その人の浮力および救命胴衣を着用していればその浮力も付加される。そのため、上方に浮力が発生するが、浮上誘導部３の下面が円弧形状であるため、水面下にとどまらず、浮力により円弧形状沿って水面上に浮かびあがることができる。
なお、図３に示す人を模した図は、水上遊具１の下側に人が潜った場合でも、円弧形状の傾きに沿って浮かびあがる様子を示す（以下の図６（Ｂ）も同じ）。 The cut surface shown in FIG. 3 has a convex portion 4 formed downward toward the water surface, and the shape thereof is an arc shape. If a person dives under the water playset 1, the buoyancy of the person and the buoyancy of the person wearing a life jacket are also added. Therefore, buoyancy is generated upward, but since the lower surface of the levitation guide portion 3 has an arc shape, it can float on the water surface along the arc shape by the buoyancy, not just below the water surface.
The figure imitating a person shown in FIG. 3 shows a state in which a person emerges along the inclination of the arc shape even when a person dives under the water playset 1 (the same applies to FIG. 6B below). ..

ここで、図３および図４に示すハッチング部は、水が充填されていることを示す（以下の図６（Ｂ）（Ｃ）および図７（Ｂ）のハッチング部も同じ）。浮上誘導部３は、その空間全部に水が満たされておらず空気が封入され空気層７が形成されている。浮上誘導部３の重量分の浮力が発生するように空気が封入されることにより、水上浮遊部２は浮上誘導部３の重量により沈むことを防止できる。
また、水上浮遊部２と浮上誘導部３の間に仕切り９が形成されている。さらに、浮上誘導部３には、流体（水または空気）注入・排出口８が複数設けられている。
なお、切断面は円弧形状であるが、円弧形状でなくても水面に向かって傾斜するような形状、例えば楕円形状であってもよいし、放物線形状でもよい。 Here, the hatched portions shown in FIGS. 3 and 4 indicate that they are filled with water (the same applies to the hatched portions of FIGS. 6 (B) (C) and 7 (B) below). The levitation guide portion 3 is formed with an air layer 7 in which the entire space is not filled with water and air is sealed. By enclosing the air so that the buoyancy corresponding to the weight of the levitation guiding portion 3 is generated, the floating portion 2 on the water can be prevented from sinking due to the weight of the levitation guiding portion 3.
Further, a partition 9 is formed between the floating portion 2 on the water and the floating guiding portion 3. Further, the levitation guide portion 3 is provided with a plurality of fluid (water or air) injection / discharge ports 8.
Although the cut surface has an arc shape, it may have a shape that is not an arc shape but is inclined toward the water surface, for example, an elliptical shape or a parabolic shape.

図５は、浮上誘導部３の凸部４の形状が、三角柱形状である水上遊具１０の斜視図である。三角柱の一つの側面が水上浮遊部２の下面に結合された状態であり、他の２つの側面が凸部４を形成している。また、浮上誘導部３には、流体注入／排出口８が複数設けられている。 FIG. 5 is a perspective view of the water playset 10 in which the shape of the convex portion 4 of the levitation guide portion 3 is a triangular prism shape. One side surface of the triangular prism is connected to the lower surface of the floating portion 2 on the water, and the other two side surfaces form the convex portion 4. Further, the levitation guide portion 3 is provided with a plurality of fluid injection / discharge ports 8.

浮上誘導部３の三角柱の２つの側面がそれぞれ水面に向かって傾斜しており、水上遊具１０の下側に潜った状態でも浮力により凸部４に沿って水面上に浮かびあがることが可能である。
このように、浮上誘導部３に凸部４を設けることにより、水上遊具１０の下側に潜った場合でも水上遊具１０の浮上誘導部３の下面が三角柱形状で、水平ではなく水面に向かって傾斜しているため、容易に水面上に浮上することができる。 The two sides of the triangular prism of the levitation guide portion 3 are inclined toward the water surface, respectively, and even when submerged under the water playset 10, it is possible to float on the water surface along the convex portion 4 by buoyancy. ..
By providing the convex portion 4 on the floating guiding portion 3 in this way, the lower surface of the floating guiding portion 3 of the floating guiding portion 10 has a triangular prism shape even when submerged under the water playing device 10, and is not horizontal but toward the water surface. Since it is inclined, it can easily rise above the surface of the water.

なお、図５の浮上誘導部３の形状の断面図は省略したが、浮上誘導部３は三角柱形状であるため、三角柱の底面に平行な断面図は三角形であり、側面の辺に平行な断面図は長方形である。 Although the cross-sectional view of the shape of the levitation guide portion 3 in FIG. 5 is omitted, since the levitation guide portion 3 has a triangular prism shape, the cross-sectional view parallel to the bottom surface of the triangular prism is a triangle, and the cross section parallel to the side surface. The figure is rectangular.

図６は、（Ａ）水上遊具の平面が円形となる平面図であり、（Ｂ）（Ｃ）円形の中心を通る２つの直交するＡ−Ａ線およびＢ−Ｂ線による断面図である。２つの切断面はいずれも円弧形状であり、浮上誘導部３の凸部４は球の中心を通らない平面で切り取った形状である。
なお、凸部４の水面下への高さは球の半径と同じかそれよりも大きい場合であってもよい。また、球を切り取った形状ではなく、放物面や楕円面を切り取った形状であってもよい。 FIG. 6 is a plan view in which (A) the plane of the water play device is circular, and (B) and (C) are cross-sectional views taken along the two orthogonal lines AA and BB passing through the center of the circle. Both of the two cut surfaces have an arc shape, and the convex portion 4 of the levitation guide portion 3 has a shape cut by a plane that does not pass through the center of the sphere.
The height of the convex portion 4 below the water surface may be the same as or larger than the radius of the sphere. Further, the shape may be a shape obtained by cutting out a paraboloid or an ellipsoidal surface instead of a shape obtained by cutting out a sphere.

図７は、（Ａ）水上浮遊具２と浮上誘導部３が分離された水上遊具３０の平面図であり、（Ｂ）Ａ−Ａ線による断面図である。図７（Ｂ）は、図３に示す断面図が、水上浮遊部２と浮上誘導部３に分離した図である。
水上浮遊具２と浮上誘導部３は分離する形態となっているため、水上浮遊部２と浮上誘導部３とは接着剤１１で固定してもよいし、水上浮遊具２と浮上誘導部３の周辺に複数のハトメ１２を設け、それぞれの上下のハトメ１２をロープ等で縛って結合してもよい。また、接着剤１１とハトメ１２を併用してもよい。
