Surfing wave-making apparatus and surfing practice facility equipped with the same

Abstract

To provide a surfing wave-making apparatus that is capable of making the so-called tubular plunging breakers which are suitable for surfing, and which have continuous crests ranging from a collapse stage to a stage immediately before collapse. The present invention comprises: a container body 110 that is open at the front thereof, is equipped with at least a bottom part, and is capable of trapping water in part of the inner space thereof; and a moving track 120 that allows the container body 110 to travel thereon and that is equipped with a slope surface track 121 and an in-pool track 123. The container body 110 falls along the slope surface track 121, plunges into water of the pool as a result of free-fall motion, and travels on the in-pool track 123 in the container body 110 decelerates, only the water held inside is thrust forward in the form of an isolated traveling wave 202 so as to produce a plunging breaker suitable for surfing.

1 . A wave-forming apparatus for producing a wave for surfing in a play area of a pool, comprising:
 a container body having at least a bottom plate capable of at least temporarily capturing water on the bottom plate;   a moving track including a slope track for moving the container body in which the container body moves along from a start position above a draft waterline of the pool to a lower position where at least a part of the container body sinks under the draft waterline of the pool; and an in-pool traveling track for moving the container body forward in a state that at least a part of the container body sunk in the pool facing the play area;   wherein the container body moves forward on the slope track and the in-pool traveling track in a state where the front surface of the container body faces the play area, and discharges the water captured by the container body toward the play area ahead.   
     
     
         2 . A wave-forming apparatus according to  claim 1 , wherein the movement of the container body in the moving track is a free fall movement on the slope. 
     
     
         3 . A wave-forming apparatus according to  claim 1 , wherein the container body comprises only a bottom plate, and the bottom plate has a slope bottom such that the front side in the advancing direction is low and the rear side is high. 
     
     
         4 . A wave-forming apparatus according to  claim 1 , wherein the container body comprises a bottom plate and a back plate. 
     
     
         5 . A wave-forming apparatus according to  claim 3  wherein the container body comprises side plates. 
     
     
         6 . A wave-forming apparatus according to  claim 3 , wherein the container body comprises a detachable weight, and the weight of the container body can be adjusted by providing the detachable weight on a part of the container body. 
     
     
         7 . A wave-forming apparatus according to  claim 1 , further comprising a lane partition wall built along the side of the traveling lane for the container body in the in-pool traveling track. 
     
     
         8 . A wave-forming apparatus according to  claim 1 , wherein the movement of the container body in the moving track adds an acceleration movement by a catapult mechanism or an acceleration movement using an elastic body provided at the position on the slope track can also be combined in addition to the free-falling movement on the slope. 
     
     
         9 . A wave-forming apparatus according to  claim 1 , wherein a plurality of container bodies are provided, and the container bodies are arranged in a row in a width direction so as to face the front surfaces of the respective containers with respect to the play area. 
     
     
         10 . A wave-forming apparatus according to  claim 1 , wherein the container body is a singular, but the width of the container corresponds to the width of the wave to be generated, and further comprising one or plural of inner partition plates provided so as to be orthogonal to the front surface in the container body. 
     
     
         11 . A wave-forming apparatus according to  claim 1 , further comprising a return traction device for pulling back the container body to a starting position again after being dropped along the slope track of the moving track,
 wherein the return traction device is provided with a connection line attached to a part of the container body, and a driving force for pulling up the connection line and pulling back the container body to the starting position above the draft waterline of the pool.   
     
     
         12 . A wave-forming apparatus according to  claim 1 , wherein the moving track employs a rail mechanism along the track as a rail type moving track. 
     
     
         13 . A wave-forming apparatus according to  claim 1 , wherein a wheel is provided between the bottom surface of the container body and the moving track. 
     
     
         14 . A surfing activity facility comprising:
 a pool and a wave-forming apparatus according to  claim 1  installed in the pool;   wherein the bottom surface of the pool is devised as including:
 a flat part following the range where the container body moves, and 
 a slope part of an upward gradient is provided in the vicinity of the start position of a play area following the flat part, 
   wherein the slope part has angle given to a moving direction in which the container body moves.   
     
     
         15 . A surfing activity facility according to  claim 14 , wherein the slope portion has a skew and has a substantially triangular shape having a vertex so as to face the container body direction.
