Description

  The present invention relates to a small submersible that is towed from a motor boat, a watercraft, etc. without power, and dives as a pilot who rides in it moves and operates a submersible wing.

  Conventionally, surfing, water skiing, diving and the like have been performed as marine sports performed in the sea, lakes, rivers and the like. However, such marine sports can only be enjoyed on the water or in a limited range in water.

  In view of this, there has been proposed an instrument that can perform both water sliding and underwater observation. For example, as this type of conventional technology, there is a device that can be used for swimming and diving by towing a boat. In this device, a pilot has a towing planing wing in a posture close to prone, and enables underwater diving by a manual operation of the pilot (see, for example, Patent Document 1).

There is also a small water vehicle that rides on a main body formed so that a person can ride in a hungry posture and can see the sea floor from a viewing window while sailing with an engine (see, for example, Patent Document 2). .
Japanese Patent Publication No. 6-509967 (2nd page, FIGS. 1 and 4) JP-A-62-213772 (2nd page, Fig. 1)

  However, in the case of the above-mentioned Patent Document 1, the entire main body in which the left and right gliding wings are integrally formed serves as a gliding wing for water surface navigation and a diving wing for underwater diving. I can't steer. Further, since the rudder is fixed, lateral control by the rudder is impossible. In addition, in the case of this Patent Document 1, since the operator slides with the front face of the operator open, a person is always in a state of water pressure, and it is difficult to perform high-speed sliding or a long-time diving.

  Furthermore, in the case of the above-mentioned Patent Document 2, since it is a water vehicle equipped with an engine, its use is limited to water, and its sportiness is not only within a range where it can be enjoyed on the water, but also has a limited range of action.

  As described above, there is no conventional technique that can easily enjoy marine sports by performing three-dimensional exercises including underwater.

  Therefore, in order to solve the above-mentioned problems, the present invention provides a submersible body formed of a streamlined cross-section outer shell provided with a space for an experienced person to ride inside, and forms a towing part at the front of the submersible body. In addition, the front part of the experience person of the submersible body is formed by a translucent part, submersible wings are provided on the left and right of the submersible body, submerged swirl wings are provided in the vertical direction of the submersible body, and the underwater swirl is provided. The wing and the underwater submersible wing are configured to be operated by the experience person. This experienced person means all humans who ride on towed submersibles.

  Further, a pair of left and right submersible wings in the towed submersible may be provided at the front part of the submersible body, and the submerged swirl wing may be provided at the rear part of the submersible body.

  Furthermore, you may comprise the said submersible wing so that an experience person can operate left and right independently.

  Further, the submersible body may have a positive buoyancy, and a towline for towing the submersible body may be configured to be detachable so as to float when not towed.

  Furthermore, an attachable / detachable part that allows an experienced person to escape may be provided in the upper part of the submersible body, and the attachable / detachable part may be configured to be removed from the interior of the submersible body.

  Further, the outer shell of the submersible body is formed with a streamlined cross section in which a passenger space is formed in the lower part of the experience person, and the experience person of the diving machine body and the front and lower parts of the passenger are made translucent. You may form with the member which has.

  The invention of the present application allows the experience person to get into the main body of the streamlined cross-section by means as described above, and the experience person can dive for a long time in three dimensions by operating the wing while being towed. It will be possible to expand the possibilities of marine sports.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a first embodiment of a towed submersible according to the present invention, FIG. 2 is a plan view of the towed submersible, and FIG. 3 is provided in the towed submersible. FIG. 4 is a perspective view showing another example of the submersible wing shown in FIG. 5 is a drawing of the underwater swirl wing provided in the towed submersible shown in FIG. 1, (a) is a perspective view, and (b) and (c) are plan views showing the operating state of the underwater swirl. It is.

  As shown in FIGS. 1 and 2, the towed submersible 1 according to the first embodiment includes a streamlined submersible body 4 in which a space 3 in which a single experiencer 2 can ride is formed. An outer shell is formed. The streamlined cross section of the submersible body 4 is formed with a buoyancy portion 5 that protrudes from the lower end of the front end to the vicinity of the head of the experiencer 2 from the lower end of the front end to the vicinity of the head of the experiencer 2. It is gently curved backward toward the waist of the experience person 2 and is formed substantially horizontally from the vicinity of the waist to the rear end. In addition, the lower surface is formed substantially horizontally from the lower part of the front end to the vicinity of the head of the experiencer 2, and after being inclined upward from the vicinity of the head of the experiencer 2, it is formed substantially horizontally toward the rear end. .

  On the other hand, as shown in FIG. 2, in plan view, after the tip is hemispherical and formed with almost the same width to the vicinity of the shoulder of the experiencer 2, the width dimension decreases along the body of the experiencer 2, The rear part is formed with substantially the same width. As shown in FIG. 1, only the rear part is open from the vicinity of the head on the lower surface, and the other part is a covered outer shell. Note that the outer surface of the cross section in the front-rear direction and the cross-section in the left-right direction shown in the figure is formed with a curved surface, and the entire structure is streamlined to reduce water resistance. In addition, as shown in the figure, the exercise performance as the submarine is enhanced by adopting a shape that allows the experience person 2 to ride and steer in a hungry posture.

  The buoyancy part 5 is for giving the submersible body 4 positive buoyancy, and is formed in such a size that the towed submersible 1 floats in a state where the experiencer 2 is not riding and towing. ing. Such a front shape of the submersible body 4 is designed to be submerged when a predetermined towing speed is reached or to reduce water resistance during towing. In addition, if the breathing-related function of the experience person 2 is incorporated in this part, the experience person 2 can get in without installing an oxygen cylinder.

  In addition, the opened lower part of the submersible body 4 is a space for the experiencer 2 to get in, and the side view of the state in which the experiencer 2 rides is excluding the lower part of the experiencer 2 as shown in FIG. The other part is covered with the submersible body 4. In this way, the submersible body 4 is formed in a so-called fairing-like form, and covers almost the whole other than the lower part of the experience person 2 who rides in a stomach-like state when towed.

  Further, a tow index clasp 6 serving as a towing portion when towed is provided at the front portion of the submersible body 4. The tow index clasp 6 is provided at a position such that when the towed submersible 1 is towed, the front portion of the submersible body 4 receives water pressure in a preferable state. The towing index clasp 6 is structured such that the tow rope 7 can be removed by an operation of the experience person 2 in an emergency or the like. The removable structure may be configured such that the part 2 that locks the tow rope 7 can be removed from the inside by the experience person 2. What is necessary is just to set suitably the position which provides this towing index clasp 6, and the form of the front part of the submersible body 4 according to the magnitude | size, use conditions, etc. of the towed submersible.

  Moreover, the front lower part (colored part in the figure) of the experience person 2 of the submersible body 4 is formed in the translucent part 8 having translucency. It is structured so that you can see it. For example, by making the field of view of the experience person 2 made of a transparent acrylic resin, it is possible to enjoy watching the surroundings.

  Underwater diving blades 9 (submersible rudder) are provided on the left and right of the front portion of the submersible body 4 so as to protrude from the surface of the submersible body 4. In addition, an underwater swirl wing 10 (vertical rudder) is provided at the rear portion of the submersible body 4 so as to protrude vertically from the upper portion of the submersible body 4. The underwater diving blade 9 is formed in a blade cross-sectional shape, and a force can be generated in the vertical direction by changing its angle. The underwater swirl blade 10 is formed in a rudder cross-sectional shape, and a force can be generated in the left-right direction by changing its angle. In this embodiment, a submersible wing 9 is provided in the front part of the submersible body 4 and a submerged swirl wing 10 is provided in the upper part of the rear part. However, the towed submersible 1 is operated by the experience person 2. Other positions may be used as long as they can be moved in three dimensions.

  As shown in FIGS. 1 and 2, the submersible wing 9 is provided in a portion where the width dimension of the diving machine main body 4 is the widest, and in this figure, the left and right can be operated independently. The submersible wings 9 provided on the left and right are configured such that the experience person 2 can change the respective angles by operating the left and right handles 11 with both hands.

  As shown in FIG. 3, the submersible wing 9 includes a bearing 14 (for example, an oil-free bearing using a polymer material) provided with a rotating shaft 12 provided at a front portion of the submersible body 4. The arm portion 13 and the handle 11 are provided inside the rotating shaft 12. Therefore, when the handle 11 is rotated back and forth, the rear portion of the submersible wing 9 is rotated in the vertical direction around the rotation shaft 12 (indicated by a two-dot chain line in the figure).

  The submersible wing 9 may be changed in size and shape in accordance with the ability of the experience person 2, and by changing the submersible wing 9, it is possible to cope with a wide range of towing speeds and change the difficulty of operation. , Can improve sportiness.

  Note that when the towing speed force is large and the reaction force is large, the operation handle may be provided with a longer arm portion 13 or a hydraulic power assist means. However, it is basically preferable in terms of experience to operate directly without using electricity or hydraulic pressure.

  In this way, by applying a downward force or an upward force to the submersible wing 9, the towed submersible 1 can be submerged or levitated at the will of the experience person 2. Moreover, if the left and right submersible wings 9 are at different angles, the towed submersible 1 can be tilted.

  FIG. 4 shows another example in which the submersible wings 9 are operated. In this example, handles 11 that move the left and right submersible wings 9 are integrally connected. Thereby, since the operation of the underwater diving blade 9 can be limited to only diving or levitation, even an inexperienced person can easily drive.

  As shown in FIGS. 1, 2 and 5 (a), the underwater swirl wing 10 is supported by a submersible body 4 by a bearing 15 (for example, an oil-free bearing using a polymer material) so as to be rotatable. The turning shaft 16 is provided, and the turning shaft 16 is rotated by a turning arm 17 provided at the lower end. The swivel arm 17 is rotated by a swivel cable 18 connected to both ends, and the swivel cable 18 is configured to be pulled at the left and right ends of a swivel bracket 19 provided near the waist of the experience person 2. Yes. The swiveling rope 18 may be a rod-shaped member. The swivel bracket 19 is configured to be rotatable about a shaft 21 supported by a bearing 20 (for example, a non-lubricated bearing using a polymer material), and has an arm portion formed forward. 22 is connected to the operation member 23 worn by the experience person 2. The operation member 23 is a belt-like member that is attached to the waist of the experience person 2. The experience member 2 attaches the operation member 23 to the waist and moves the waist to the left and right, whereby the turning bracket 19 rotates about the shaft 21, and the turning cable 18 connected to the left and right ends by the turning of the turning bracket 19. When the swivel arm 17 is pulled and the swivel shaft 16 is rotated, the underwater swirl blade 10 is rotated.

  Thus, these submersible wings 9 and swirl wings 10 are structures that can be moved by direct manipulation of the experience person 2, and three-dimensional including underwater by operating these diving wings 9 and swirl wings 10. It is structured so that you can exercise freely.

  As shown in FIGS. 5B and 5C, the configuration in which the underwater swirl blade 10 is rotated by the operation member 23 is configured by moving the operation member 23 to the right as shown in FIG. And the swivel arm 17 is swung via the swivel cable 18, whereby the underwater swirl blade 10 can be swung rightward about the swivel shaft 15. Further, as shown in (c), when the operating member 23 is moved to the left, the turning bracket 19 is turned to turn the turning arm 17 through the turning cable 18, whereby the underwater turning blade 10 is turned to the turning axis. It can be turned to the left about 15. In this way, the towing submersible 1 can be turned left or right by applying a leftward or rightward force to the underwater swirl wing 10. Thus, the underwater diving wing 9 and the underwater swirl wing 10 are configured such that the experience person 2 can directly operate them.

  FIG. 6 is a side view showing a usage state of the towed submersible shown in FIG. Although the configuration is schematically shown in this figure, a towed ship may be a motor boat or a water bike that can tow the towed submersible 1. As shown in the figure, in this embodiment, the experiencer 2 wears an oxygen cylinder 24 and a regulator (not shown) and gets into the towed underwater diving machine 1 in a stiff posture. In this towed submersible 1, a towed index clasp 6 provided at the front and a towed ship 25 are connected by a towed rope 7, and a towed type towed by advancing the towed ship 25. The submersible 1 obtains a driving force. W is the water surface.

  In such a towed state, the experience person 2 can dive by operating the underwater diving wing 9 provided at the front part with the handle 11. This diving depth is determined by the shape of the front part of the submersible body 4, the towing speed, the angle of the underwater diving blade 9, and the like. When being towed in this way, the experience person 2 can change the posture of the towed submersible 1 by directly operating the angle between the submersible wing 9 and the underwater swirl wing 10. Specifically, the submersible wing 9 can be submerged or floated by moving the submersible wing 9 in the same direction with both hands, and the towed submersible 1 can be tilted by operating the left and right submersible wings 9 independently. Further, it is possible to turn right or turn left (direction control) by moving the hips left and right and moving the underwater swirl wing 10 left and right.

  Moreover, when being towed while changing its attitude in the water, it is a fairing type underwater vehicle that covers almost the entire experience 2 with the outer shell of the towed submersible 1. Therefore, the resistance of water acting on the experience person 2 can be reduced as much as possible to perform stable underwater navigation, and diving with less fatigue can be performed even for a long time.

  Further, when some trouble occurs while being towed, if the experience person 2 operates the tow indexing clasp 6 and removes the tow rope 7, the towed submersible 1 itself Since it can float up to the water by the positive buoyancy it possesses, even if the experience person 2 feels bad in the water, it can easily float up to the water surface.

  As described above, since the towed submersible 1 can easily perform three-dimensional motion including underwater, enjoy an unusual marine sport for underwater that is not usually a place of activity. It becomes possible. In addition, it can be enjoyed even when used for watching underwater while observing underwater from a range of fields of view that allows you to perform diving with high sportiness during high-speed towing and to see through the surrounding water during low-speed towing. . For example, in addition to new demand as a marine sport that has never existed before, by installing an underwater TV camera in the forefront, it is possible to shoot dynamic underwater video that moves at high speed in the water.

  Therefore, a small underwater vehicle that can be submerged by the submersible wing 9 can be realized, has excellent underwater motion performance, and the submersible itself is streamlined, so that it is possible to dive without excessive physical strength and to get in Leisure products with sportiness can be provided because humans steer themselves. In addition, since it is a towing type that does not have power, it can be provided as a product that can be freely submerged at high speed underwater in a compact, simple and inexpensive manner.
