Description

【０００１】
【産業上の利用分野】
この発明は、競艇場に於ける緩衝部を有する消波装置に関し、詳しくはレ−ス艇が一斉に航走する競艇場水面に設けられている公知の消波装置よりも、大きなうねりや、小さな波をも消波可能な競艇場に於ける緩衝部を有する消波装置に関する。
【０００２】
【従来の技術】
競艇場に於ては、競争水面を６隻のレ−ス艇が約８０ｋｍ／ｈの高速度で楕円形を描きながら所要回数一斉に航走して競争する。従って、これらレ−ス艇が航走して造波する引き波の外に、風等の自然条件により発生する波が岸壁、その他の競艇場内の機器に衝突し、跳ね返って来た返し波等により各レ−ス艇の航走の障害となり、各レ−ス艇の転覆の原因となる場合がある。
【０００３】
前述の通り、各レ−ス艇は、約８０ｋｍ／ｈの高速度で航走するので、コ−ナ部のタ−ンの際各レ−ス艇は横滑りして岸壁、ポ−ル、塔、その他の機器に衝突したり、又安定を失ってレ−ス艇から投出された選手は、岸壁又はこれらの機器に衝突して負傷し、最悪の場合は死亡事故に至る事がある。
【０００４】
（１）公知の競艇場に於ける消波装置に於いては、図１３に示す通り、断面三角形競争水面側消波本体と、断面三角形岸壁側消波本体とを連結金具を介して連結して形成されたＵ字形消波空間内に、該競争水面側消波本体表面板を乗越えて来た波を該Ｕ字形消波空間内に落下させ、該Ｕ字形消波空間内に落下させて巻き込みながら消波させ、該Ｕ字形消波空間の底部に設けられた消波開口部から水中に導き、それでも消波されない波を該断面三角形岸壁側消波本体の表面板を乗越えて来た波と共に岸壁側に導いている。
【０００５】
（２）前述の該断面三角形競争水面側消波本体と、該断面三角形岸壁側消波本体とを連結して組立てた消波装置の各ブロックは、長手方向に比較的短く製作されていた。
【０００６】
（３）そして、該消波装置の該断面三角形競争水面側消波本体に設けられる緩衝部は、三角形の緩衝部取付金具を介して固着している。
【０００７】
【発明が解決しようとする課題】
前述の通り、公知の消波装置に於ては、次の様な諸欠点が生じた。
（１）前述の通り、公知の競艇場に於ける消波装置（特公昭５４−３５８０９号、同６１−３９８３３号、発明者浜村敏夫、この発明者の亡兄）に於ては、図１３に示す通り、断面三角形競争水面側消波本体と、断面三角形岸壁側消波本体とを連結金具を介して連結して形成されたＵ字形消波空間内に、該競争水面側消波本体の表面板を乗越えて来た波を該Ｕ字形消波空間内に落下させて巻込みながら消波させ、該Ｕ字形消波空間の底部に設けられた消波開口部から水中に導き、それでも消波されない波を該断面三角形岸壁側消波本体の表面板を乗越えて来た波を岸壁側に導いている。
しかし、部品を連結パイプ、連結金具等を介して一体に連結する構成なので、構造的に弱点があり、部品点数が増加し、その結果製造工程が複雑となり、所望競艇場への運搬、競争水面上での組立、取付工事等が厄介で非能率であった。
【０００８】
（２）又、公知の競艇場に於ける消波装置に於ては、コ−ス側及び該岸壁側略断面三角形形中空体との間に、Ｕ字形消波空間が形成されるので、波の抵抗を受け易く、大きなうねりは当然のこと、小さな波でも揺れて充分な消波効果が得られなかった。
【０００９】
（３）更に、公知の競艇場に於ける消波装置は、図１３に示す通り、緩衝部がコース側略断面三角形中空体の傾斜面から延長する様に設けられているので、競争水面のコースから外れたレース艇が該緩衝部に衝突した場合、斜め上方に導かれるのでレース艇の安定性が損なわれ、効果的な緩衝効果が得られなかった。
【００１０】
（４）加えて、公知の消波装置の連結部が多く、その連結部が脆弱となるので、その部分を補強する必要があった。
【００１１】
【発明を解決するための手段】
この発明は、前述の公知の競艇場の消波装置の諸欠点を除去するもので、その第１要旨は、表面長手方向に複数の略鋸歯状消波段部と波落下用開口部とを形成し、且つ、表面長手方向所要間隔でそれと直交する様に形成された連結金具嵌合用Ｕ字形凹部とを有する傾斜板と、該傾斜板の後端部から下方に延長し、中間部に段部を形成し、該段部を挟んで夫々波通過用開口部を形成した波落下面と、該波落下面の下端部から水平に延長し、且つ、一定間隔で波落下用開口部を形成した底板と、該底板の先端から直角下方に延長する垂直片と、該傾斜板の先端部から該段部に向かって一体に設けられた水平補強板と、該水平補強板の下面に一体に設けられた浮力体と、該傾斜板の両端部に一体に設けられた側板とを有する略断面傘形コース側中空体と；波落下面の後端部から延長する水平面を除いて該略断面傘形コース側中空体と同一の構成を有し、該略断面傘形コース側中空体と対称的に連結される略断面傘形岸壁側中空体と；該コース側及び岸壁側中空体との該連結金具嵌合用Ｕ字形凹部内に嵌合され、該コース側及び岸壁側中空体とを一体に連結する山形角パイプと、該山形角パイプの水平面上で長手方向に直交して一体に設けられたシリンダと、該シリンダ内に収納され、最奥部の壁に後端部が貫通固定されたボルトと、該シリンダ内に部分的に摺動自在に嵌合され、後端部が該ボルトの前端部に連結されたピストンと、後端部が該シリンダ内の最奥部の壁に固着し、該ボルトの周囲に巻回され、且つ、前端部が該ピストンの後端部に固着された圧縮スプリングと、下端が該ピストンの前端部と一体でそれと鈍角を形成するＬ字形枠体と、該鈍角Ｌ字形枠体の長手方向に一体に固着されたガード・レイルとを有し、且つ、該圧縮スプリングを介してコース側に常時付勢される緩衝部と；該シリンダ上で長手方向に一定間隔で固着されたＣ形鋼と；該略断面傘形コース側中空体と該略断面傘形岸壁側中空体とを対称的に連結して一体とされた消波体の底板に突設された垂直片により形成された逆Ｔ字形フィンとから成る競艇場に於ける緩衝部を有する消波装置である。

【００１３】
前述の通り、公知の消波装置に於ける断面三角形岸壁側消波本体の底部に形成されるＵ字形消波空間を形成していた。この特許出願に係る発明に於ては、このＵ字形消波空間を廃止し、同一の構成を有するコ−ス側及び岸壁側略断面傘形中空体とを対称的に連結して設けられる消波体とし、その略鋸歯状消波段部と波落下用開口部とにより該コ−ス側略断面傘形中空体内に導びき、水中に落下させて消波し、大きな波（うねり）と小さな波とを効果的に消波する競艇場に於ける緩衝部を有する消波装置である。

【００２６】
【発明の作用】
前述の構成を有するこの発明の競艇場に於ける緩衝部を有する消波装置１０は、波落下面の後端部から延長する水平面を除いて同一な構成を有するコ−ス側及び岸壁側略断面傘形中空体とを対称的に連結して設けられる消波装置の底部に形成されたＵ字形消波空間を廃止し、略鋸歯状消波段部と波落下用開口部とにより該コ−ス側略断面傘形中空体内に導びき、水中に落下させ消波し、大きな波（うねり）と小さな波とを効果的に消波する競艇場に於ける緩衝部を有する消波装置である。
【００２７】
【発明の効果】
（１）前述の通り、この発明の競艇場に於ける緩衝部を有する消波装置１０は、波落下面１４の後端部から延長する水平面１２ｃを除いて、コ−ス側と岸壁側との略断面傘形中空体Ａ、Ｂとが同一の構成を有するものであるから、製作の際の金型の製作が容易となるので、従って製作、運搬、組立等も極めて容易となる。
【００２８】
（２）そして、図１１、１２に示す通り、競艇場のコ−ス側水面からの波は、該コ−ス側略断面傘形中空体Ａの該傾斜板１２の表面長手方向に複数の略鋸歯状消波段部１２ａ、１２ａの抵抗により部分的に消波され、該波落下用開口部１２ｂ、１２ｂから該傾斜板１２の下側に導かれ、且つ、該水平補強板２０からその長手方向に導かれて水中に落下して消波され、更に該波通過用開口部１４ｂから該波落下面１４を経て底部に落下し、且つ、該傾斜板１２の表面を越えた波も該波落下面１４を経て底部に落下して消波される。
【００２９】
（３）更に、該傾斜板１２の下側、該波落下面１４の裏側及び該水平補強板２０の上面とで形成された該波導入空間部Ｅに於て、該波通過用開口部１４ｂ、１４ｂから排出されない波は、該略断面傘形コ−ス側中空体Ａの長手方向両端に導びかれて水中に落下させて消波される。
【００３０】
（４）しかも、該コ−ス側略断面傘形中空体Ａによっても消波されず、該略断面傘形中空体Ｂを越える波は、該傾斜板１２によって消波され、前記（２）、（３）記載の通り、該波通過用開口部１４ｂから該三角形波導入空間部Ｅ内に導かれた波も、該略断面傘形岸壁側中空体Ｂの長手方向両端に導びかれ、水中に落下して消波される。
【００３１】
（５）公知の消波装置の底部に突設状態で形成されたＵ字形消波空間を廃止したので、従来コ−ス側水面から受けるうねりの抵抗が少なくなる。
【００３２】
（６）加えて、競艇場の水深に応じて該コ−ス側及び該岸壁側略断面傘形中空体Ａ、Ｂの底面に突出された該垂直片１８、１８により形成される該逆Ｔ字形フィンＣの高さを調節する必要がある場合、該逆Ｔ字形フィンＣの該ボルト１８ｂを外して、所要の高さを有するＬ字形鋼１９ａと交換して再び螺合すれば、極めて容易に交換可能となり、該逆Ｔ字形フィンＣの高さ調節も容易となる。
【００３３】
（７）コーナ部のターンの際レース艇は横滑りして該緩衝部 F に衝突した場合、公知の緩衝部 f に相違して該緩衝部 F が該圧縮スプリング２８ b により常時コース側に付勢されているので、水平に作動してレース艇へ加わる衝撃が吸収され、該レース艇が復帰し、その安定性が損なわれるので操縦している選手の安全を図ることが出来る。

【００３４】
（８）更に、該逆Ｔ字形フィンＣが船舶特にボ−トに於けるセンタ−・ボ−ド又はウエイト・バランサとして機能するので浮遊状態で設けられる消波装置１０の安定に役立つものである。

[Industrial applications]
The present invention relates to a wave canceling device having a buffer portion in a boat racetrack, and more specifically to a wave canceling device having a greater swelling than a known wave breaking device provided on the water surface of a boat racetrack where race boats run simultaneously. The present invention relates to a wave canceling device having a buffer in a boat racetrack capable of breaking even small waves.
[0002]
[Prior art]
At the racetrack, six racing boats race in the elliptical shape at a high speed of about 80 km / h at the required number of times on the competition surface. Therefore, in addition to the wake created by the racing boats, the waves generated by natural conditions, such as wind, collide with the quay and other equipment in the racetrack, and return waves, etc. This may hinder the sailing of each raceboat and cause each raceboat to capsize.
[0003]
As described above, since each boat sails at a high speed of about 80 km / h, each boat slides sideways at the turn of the corner to pier, pier, and tower. Athletes thrown from a race boat after colliding with other equipment or losing stability and colliding with a quay or these equipment may be injured and, in the worst case, lead to death.
[0004]
(1) In its at the in wave dissipating device known Motorboat field, as shown in FIG. 13, connected through the triangular sectional competition waterside wave dissipating body, the connecting fitting and triangular section dockside wave-absorbing body In the U-shaped wave-dissipating space formed as above, the wave that has climbed over the surface plate of the competing water-side wave-dissipating main body is dropped into the U-shaped wave-dissipating space, and is dropped into the U-shaped wave-dissipating space. The wave was guided while being entangled, and was guided into the water through the wave-dissipating opening provided at the bottom of the U-shaped wave-dissipating space. It leads to the quay along with the waves.
[0005]
(2) Each block of the wave absorber assembled by connecting the above-mentioned triangular cross-section competing water surface side wave-dissipating main body and the above-mentioned triangular cross-section quay side wave-dissipating main body was manufactured to be relatively short in the longitudinal direction.
[0006]
(3) The buffer provided on the wave-eliminating body on the water surface side on the triangular cross section of the wave-absorbing device is fixed via a triangular buffer mounting bracket.
[0007]
[Problems to be solved by the invention]
As described above, the known wave absorber has the following disadvantages.
(1) As described above, FIG. 13 shows a known wave canceling device in a boat racetrack (Japanese Patent Publication Nos. 54-35809 and 61-39833, the inventor Toshio Hamamura, and the inventor's brother). As shown in the figure, the competing water surface side wave-dissipating body is formed in a U-shaped wave-shaping space formed by connecting the cross-section triangular competing water-side wave-dissipating body and the cross-sectional triangular quay side-side wave-dissipating body via a connection fitting. The waves that have climbed over the surface plate are dropped into the U-shaped wave-dissipating space, and are wave-damped while being entangled. The waves are guided into the water from the wave-dissipating opening provided at the bottom of the U-shaped wave-dissipating space. Waves that are not waved are guided over the surface plate of the main body on the quay side on the triangular quay side to the quay side.
However, since the components are integrally connected via connecting pipes, connecting brackets, etc., there are structural weak points, the number of components increases, and as a result, the manufacturing process becomes complicated, and transportation to a desired boat racetrack and competitive water surface are required. The above assembly and installation work were troublesome and inefficient.
[0008]
(2) Further, in a known wave-breaking device at a boat racetrack, a U-shaped wave-breaking space is formed between the course side and the quay side substantially triangular hollow body. It was easy to receive the resistance of the waves, and of course large swells were shaken, and even small waves were not able to obtain a sufficient wave-eliminating effect.
[0009]
(3) Further, as shown in FIG. 13 , the known wave-breaking device in a racetrack has a buffer portion extending from an inclined surface of a hollow body having a substantially triangular cross section on the course side. When a racing boat off the course collides with the buffer, the boat is guided diagonally upward, so that the stability of the racing boat is impaired and an effective buffering effect cannot be obtained.
[0010]
(4) In addition, there are many connecting portions of the known wave canceling device, and the connecting portions are weakened, so that the portions have to be reinforced.
[0011]
[Means for Solving the Invention]
The present invention eliminates the above-mentioned drawbacks of the known wave canceling device for a racetrack. The first gist of the present invention is to form a plurality of substantially sawtooth wave breaking steps and a wave drop opening in the longitudinal direction of the surface. An inclined plate having a U-shaped recess for connecting fittings formed at a required interval in the surface longitudinal direction so as to be orthogonal thereto, and extending downward from a rear end of the inclined plate, and a stepped portion at an intermediate portion. Was formed, and a wave dropping surface formed with a wave passing opening portion with the step portion interposed therebetween, and a horizontal wave extending from a lower end portion of the wave falling surface, and a wave dropping opening portion was formed at regular intervals. a bottom plate, and a vertical piece extending perpendicularly downward from the front end of the bottom plate, a horizontal reinforcing plate provided integrally toward the stepped portion from the tip of the inclined plate, integral with the lower surface of the horizontal reinforcing plate A substantially section-shaped umbrella-shaped course-side hollow having a provided buoyant body and side plates integrally provided at both ends of the inclined plate When; it has the same configuration as the cross-sectional schematic representation umbrella course side hollow bodies except horizontal plane extending from the rear end portion of the wave falling surface, substantially coupled and symmetrically cross-sectional schematic representation umbrella course side hollow bodies An angled square pipe fitted into the U-shaped recess for fitting the fitting with the course-side and quayside hollow bodies, and connecting the course-side and quayside hollow bodies together. A cylinder integrally provided perpendicular to the longitudinal direction on the horizontal plane of the angled square pipe, a bolt housed in the cylinder, and a rear end portion of which is fixedly penetrated to the innermost wall; A piston having a rear end connected to a front end of the bolt and a rear end fixed to the innermost wall in the cylinder; And a compression spring having a front end fixed to the rear end of the piston and a lower end fixed to the piston. An L-shaped frame integrally formed with the front end of the ton and forming an obtuse angle with the front end of the ton; a guard rail integrally fixed in a longitudinal direction of the obtuse-angle L-shaped frame; and a course formed through the compression spring. A buffer section constantly urged to the side; a C-shaped steel fixed at regular intervals in the longitudinal direction on the cylinder; a substantially umbrella-shaped course-side hollow body and a substantially umbrella-shaped quayside hollow body; symmetrically connected a wave dissipating device having at buffer section in Motorboat field consisting of an inverted T-shaped fins formed by vertical pieces are butt set to the bottom plate of the wave dissipating body that is integrated.
[0012]
Its second gist, the height of the reverse T-shaped fins formed by said vertical piece is butt set to the bottom plate with the course side and該岸wall schematic sectional umbrella hollow body, if desired, adjusted This is a wave canceling device having a buffer portion in a flexible boat racetrack.
[0013]
As described above, the U-shaped wave-dissipating space formed at the bottom of the wave-dissipating body having a triangular cross-section in a known wave absorber is formed. In the invention according to this patent application, the U-shaped wave-eliminating space is abolished, and a noise-suppressing space provided by symmetrically connecting the course-side and quay-side hollow umbrella-shaped hollow bodies having the same configuration is provided. The corrugated body is guided into the hollow body having a substantially umbrella-shaped cross section on the course side by the substantially serrated wave-breaking step portion and the opening for wave fall, and is dropped into water to extinguish the wave, and a large wave (undulation) is generated. This is a wave breaking device having a buffer portion in a boat racetrack that effectively breaks waves.
[0014]

【The invention's effect】
(1) As described above, in the boat racetrack according to the present invention, the wave breaking device 10 having the buffer portion is provided on the course side and the quay side except for the horizontal surface 12c extending from the rear end of the wave falling surface 14. Since the umbrella-shaped hollow bodies A and B having substantially the same cross section have the same configuration, it is easy to manufacture a mold at the time of manufacture, and therefore, the manufacture, transportation, assembly and the like are extremely easy.
[0028]
(2) As shown in FIGS. 11 and 12, the waves from the water surface on the course side of the boat racetrack have a plurality of waves in the longitudinal direction of the surface of the inclined plate 12 of the hollow body A having a substantially umbrella-shaped cross section on the course side. Waves are partially eliminated by the resistance of the substantially sawtooth-shaped wave-dissipating step portions 12a, 12a, guided to the lower side of the inclined plate 12 from the wave-falling openings 12b, 12b, and extended from the horizontal reinforcing plate 20 to the longitudinal direction. It is guided in the direction, falls into the water, is wave-dissipated, and further falls from the wave passage opening 14b through the wave falling surface 14 to the bottom, and the wave that has passed over the surface of the inclined plate 12 is also the wave. It falls to the bottom through the falling surface 14 and is eliminated.
[0029]
(3) Further, in the wave introduction space E formed by the lower side of the inclined plate 12, the back side of the wave falling surface 14, and the upper surface of the horizontal reinforcing plate 20, the wave passage opening 14b is formed. , 14b are guided by both ends in the longitudinal direction of the umbrella-shaped course-side hollow body A and dropped into water to be eliminated.
[0030]
(4) Moreover, the waves are not canceled by the course-side hollow umbrella-shaped hollow body A, and the waves passing through the hollow umbrella-shaped hollow body B are canceled by the inclined plate 12, and the above-mentioned (2) As described in (3), the wave guided into the triangular wave introduction space E from the wave passage opening 14b is also guided to both ends in the longitudinal direction of the substantially umbrella-shaped quay-wall-side hollow body B, It falls into the water and is extinguished.
[0031]
(5) Since the U-shaped wave-breaking space formed in a projecting state at the bottom of the known wave-breaking device is eliminated, the resistance of the undulation from the conventional course-side water surface is reduced.
[0032]
(6) In addition, the inverse T formed by the vertical pieces 18, 18 protruding from the bottom surfaces of the umbrella-shaped hollow bodies A, B on the course side and the quay side according to the water depth of the boat racetrack. When it is necessary to adjust the height of the fin C, it is extremely easy to remove the bolt 18b of the inverted T fin C, replace it with an L-shaped steel 19a having a required height, and screw it again. And the height of the inverted T-shaped fin C can be easily adjusted.
[0033]
(7) the race boat when corners of the turn is skidding when colliding with the buffer unit F, always urged course side the buffer unit F differ in the known buffer portion f is by the compression spring 28 b As a result, the shock acting on the race boat when it is operated horizontally is absorbed, the race boat returns, and its stability is impaired, so that the safety of the maneuvering athlete can be improved.

[0034]
(8) Further, since the inverted T-shaped fin C functions as a center board or a weight balancer in a ship, especially in a boat, it is useful for stabilizing the wave absorber 10 provided in a floating state. .
