Description of the Related Art Conventionally, there is a water vehicle that is propelled by an accelerating / decelerating operation while an occupant sitting on a seat provided on a rear portion of a deck steers a steering handle provided on a front portion of the deck. In such a water vehicle, the hull is composed of a hull and a deck, a steering handle for steering is provided at the front side portion of the deck, and a seat for a passenger to ride on the rear side portion of the deck is provided. And a space for movement is provided on the deck (see, for example, Patent Document 1).

In this water vehicle (small jet propulsion boat), a blue work is formed on the outer peripheral portion of the deck except the rear side portion, and a seat is also provided on the front portion of the steering handle on the upper surface of the deck. And the part between the part provided with the steering handle and both seats on the upper surface of the deck and the blue work is formed on a flat floor surface. For this reason, the passenger | crew can move along a planar floor surface.
Japanese Patent Publication No. 2769330

  However, in the above-described conventional water vehicle, since a large weir-shaped blue work is formed in addition to the rear side portion at the outer peripheral edge portion of the deck, the portion formed in a planar shape on the upper surface of the deck The area is less. For this reason, the range in which the occupant can move becomes narrow and difficult to move on the deck, or when the top surface of the deck is used as a space for placing luggage, the space becomes narrow and loadability decreases. Or

  In addition, when the water vehicle is subjected to waves and water accumulates on the deck, the water can be discharged only from the rear part of the deck, resulting in poor drainage. In addition, when a crew member gets into a water vehicle from underwater, the blue work becomes in the way, so there is a problem that it can only be boarded from the rear side where the blue work is not formed, and the front part of the steering handle on the upper surface of the deck is also seated Therefore, there is a problem that it is difficult to provide an intake port for taking outside air into the engine room.

  The present invention has been made in order to cope with the above-described problems, and the purpose of the present invention is to allow an occupant to freely move on the upper surface of the deck and to improve the loadability and drainage on the upper surface of the deck. It is to provide a water vehicle.

  In order to achieve the above-mentioned object, the structural feature of the water vehicle according to the present invention is that a hull is composed of a hull disposed on the lower side and a deck disposed on the upper side, and a steering handle is provided on the upper surface of the deck. And a straddle-type seat, an engine and a jet pump are provided in the boat body, and the water vehicle is driven by operating the jet pump by driving the engine. Thus, a base-like steering seat base is provided at the central portion of the upper surface of the deck, and a steering handle and a straddle seat are provided above the steering seat base.

  In the water vehicle according to the present invention configured as described above, since the blue work provided in the conventional water vehicle is not provided, the substantially planar portion on the upper surface of the deck can be widened. For this reason, the range of movement of the occupant on the upper surface of the deck is widened, and the occupant can easily move on the deck while the water vehicle is anchored. As a result, the water vehicle can be used not only for propulsion but also for fishing, such as fishing on the deck in a stopped state. In addition, since the place for placing luggage etc. on the upper surface of the deck becomes wider, for example, when fishing with the water vehicle stopped on the surface of the water, it is often placed with box-like items such as fishing gear and cooler boxes. become able to.

  Furthermore, since the substantially planar portion of the upper surface of the deck is formed up to the periphery of the deck, even if the water vehicle is subjected to waves, the water of the waves can be drained from any part of the outer periphery of the deck. . This prevents water from accumulating on the deck and ensures high drainage. In addition, when no fence or the like is provided on the outer peripheral edge of the deck, when the occupant gets on the water vehicle from underwater, it can be boarded from any part around the water vehicle. In addition, the substantially planar shape in the present invention means not only a complete plane but also a surface with some unevenness, and there may be unevenness that does not hinder the occupant to move or place an object. To do.

  Another structural feature of the water vehicle according to the present invention is that an intake port for taking outside air into the engine room in which the engine is accommodated is provided in front of the steering seat base. According to this, since the intake port can be opened in the traveling direction of the water vehicle, it is easy to introduce outside air into the engine room. In addition, since the air intake vent is located above the top surface of the deck, water can enter the engine room from the air intake vent even when the deck is exposed to waves or water temporarily accumulates on the top surface of the deck. It becomes difficult to do.

  Still another structural feature of the water vehicle according to the present invention is to prevent air from entering the engine room by separating air and water between the air inlet and the engine room. A water separation structure is provided. As this water separation structure, various structures can be used. For example, the flow path through which the air flows is once extended upward from the intake port and then directed to the lower engine room, and water is formed in the intake port. When the water enters the water, the water can return to the inlet side without passing over the upper end of the flow path, or can flow to the lower deck side. In addition, a water separation structure can be configured by providing a filter that allows air to pass but does not allow water to pass through the intake port. According to this water separation structure, it is possible to more reliably prevent water from entering the engine room.

  Still another structural feature of the water vehicle according to the present invention is that the distance from the front end of the steering seat base to the front end of the hull is determined from the rear end of the steering seat base to the rear end of the hull. The distance is longer than that. According to this, since the seat on which the occupant sits is located at the rear side of the water vehicle, when the water vehicle is propelled, the tip of the heel is positioned upward, the balance of the water vehicle is improved, and the speed feeling is improved. A certain promotion becomes possible. In addition, when an air inlet is provided on the front surface of the steering seat base, the distance from the air inlet to the front end of the hull is increased, so that water does not easily enter the air inlet.

  Still another structural feature of the water vehicle according to the present invention is that a grip portion is provided in the vicinity of the steering wheel at the upper portion of the steering seat base so that the occupant can grip it when moving on the deck. According to this, since the grip can be held when the occupant moves on the deck, the occupant can easily move in a stable posture on the deck. In this case, it is preferable that the grip portion is formed of a handrail such as a handrail made of a pipe or a rod or a lever-like one and is installed in a place where the hand can be easily gripped.

  Still another structural feature of the water vehicle according to the present invention is that the grip portion is provided at a position lower than the steering wheel. According to this, the grip portion does not block the sight of the occupant during the operation of the water vehicle.

  Still another structural feature of the water vehicle according to the present invention is that a rail portion made of a tubular member or a rod-like member is provided in a predetermined portion of the peripheral portion of the deck. According to this, it is easy for passengers to move on the deck without losing the area of the substantially planar portion on the top surface of the deck, or when the luggage is loaded on the deck, the fall of the luggage is prevented. can do. In addition, a holder for attaching a wakeboard, a fishing rod, a mirror or the like can be attached to the rail portion. In addition, this rail part may be provided in the perimeter of the peripheral part of a deck, and may be provided in a part.

  Still another structural feature of the water vehicle according to the present invention is that a front side portion of the steering seat base portion on the upper surface of the deck includes a concave portion recessed downward from the upper surface of the deck and a lid body covering the upper surface opening of the concave portion. Is provided with a receiving portion. The front part inside the hull is usually a dead space where no engine, pump, etc. are installed. It is possible to effectively use the dead space without damaging it. This accommodating part can be used in order to accommodate an anchor, a ladder, or the like.

  Further, another structural feature of the water vehicle according to the present invention is that the lower end portion of the recess in the housing portion is positioned below the draft line of the hull, and the lower end portion of the recess is externally provided. This is because a water introduction path through which water can be introduced into the recess is communicated. According to this, when an object is not accommodated in an accommodating part, it can be used as a ginger for storing the fish which collected water in the recessed part. In addition, a detachable stopper is attached to a portion of the introduction path that opens to the concave portion, and water is prevented from entering the concave portion when an object is accommodated in the accommodating portion.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 5 show a water vehicle 10 according to the embodiment.

  In addition, a space is provided between the front end portions of the rail portions 25a and 25b so that the occupant can pass therethrough, and the front portion of the rib portion 24 is slightly ahead of the portion where the front end portions of the rail portions 25a and 25b are located. Are formed with a pair of grooves 24a and 24b to which water on the deck 11b can be discharged and a ladder 23 can be attached. FIG. 9 shows a state in which the ladder 23 is attached to the groove portions 24a and 24b. By attaching the ladder 23 in this manner, the occupant is transferred to the ladder 23 and enters the water from the upper surface of the deck 11b, or from the water. It can go up on the upper surface of the deck 11b.

  Further, the rail portions 25a and 25b are used as a backrest and a holder for fixing a fishing rod when the occupant relaxes on the upper surface of the deck 11b with the water vehicle 10 stopped on the water. Or can be used for Furthermore, it can also be used for attaching a mirror or a wakeboard for the driver sitting on the seat 13 to look backward. Further, as shown in FIG. 3, groove portions 24 c and 24 d similar to the groove portions 24 a and 24 b are also formed on both side portions of the rear end portion of the rib portion 24. A plurality of grooves 24e for drainage are formed while maintaining the above.

  Although not shown, an engine is provided in the center of the bottom portion in the hull 11, and a crankshaft extends rearward in the hull 11 from the rear of the engine. An impeller shaft is connected to the crankshaft, and the impeller shaft is connected to a jet propulsion device provided at the stern of the hull 11. The impeller shaft is connected to an impeller attached to the inside of the jet propulsion device, and transmits the rotational force of the crankshaft driven by the engine to the impeller to rotate the impeller.

  The jet propulsion device further includes a water introduction port that opens to the bottom of the hull 11 and an injection nozzle that opens to the stern, and causes the water introduced from the water introduction port to be injected from the injection nozzle by the rotation of the impeller. Propulsion is generated in the hull 11. And the steering nozzle 26 is attached to the rear part of the injection nozzle. The steering nozzle 26 is connected to the steering handle 15 by an operation wire, and swings left and right in accordance with the operation of the steering handle 15. Further, a ladder 27 for switching the traveling direction of the water vehicle 10 between the front and the rear is attached to the rear of the steering nozzle 26.

  In addition, at the rear end of the hull 11a of the hull 11, a substantially U-shaped reboarding step comprising a pair of substantially vertical portions extending upward with a space therebetween and a horizontal portion connecting both ends of the substantially vertical portions. 28 is attached. The reboarding step 28 is biased upward by a spring, but is configured to descend in a substantially horizontal direction by applying a load downward, and is lowered when the occupant gets on board from underwater. Used. Further, in the center of the rear portion of the steering seat base portion 12, there is provided an attachment portion 12a comprising a pair of rod-like portions extending in parallel to the rear portion and a ring-like portion formed at the tip thereof.

  In the above configuration, when driving the water vehicle 10, the driver and the passenger can board the boat. The driver holds the grip of the steering handle 15 with the start switch (not shown) installed in the vicinity of the steering handle 15 turned on, and moves the throttle lever provided in the vicinity of the grip to the grip side. By moving it, the jet propulsion device is driven, and a jet flow is ejected from the ejection nozzle, and the water vehicle 10 starts to travel.

  In this case, the closer the throttle lever is to the grip side, the faster the engine rotates and the water vehicle 10 is propelled at a higher speed, and the further away the throttle lever is from the grip, the engine rotates slower and the water vehicle 10 runs at a lower speed. Further, by rotating the steering handle 15 clockwise in plan view, the steering nozzle 26 rotates to the right and the water vehicle 10 turns to the right, and the steering handle 15 rotates counterclockwise in plan view. By rotating, the steering nozzle 26 rotates to the left, and the water vehicle 10 turns to the left. During this time, the occupant can drive the water vehicle 10 in an easy posture while sitting on the seat 13 and the auxiliary seat 14. At that time, the passenger sitting on the auxiliary seat 14 can maintain a stable state by gripping the grip portions 14 a and 14 b provided at the lower portion of the auxiliary seat 14.

  When the propelling water vehicle 10 is subjected to waves, the water does not collect on the upper surface of the deck 11b but flows from a predetermined portion of the outer peripheral portion of the deck 11b to the water surface. Even if a small amount of water remains on the upper surface of the deck 11b, the water falls from the grooves 24a, 24b, 24c, 24d, and 24e onto the water surface. In addition, when a mirror is attached to the rail portion 25a or the rail portion 25b, the driver can confirm the rear with the mirror without looking back.

  In addition, the water vehicle 10 can be stopped on the water for fishing or swimming. In this case, the anchor is accommodated in the concave portion 21a of the accommodating portion in advance, and the water vehicle 10 is maintained in the stopped state by taking out the anchor from the concave portion 21a and throwing it into the water. At this time, the occupant can move in a stable posture on the deck 11 b by holding the handrail 18. Further, it is possible to fish by sitting on the deck 11b with the rail portions 25a, 25b as a backrest, or by fishing with a fishing rod fixed to the rail portions 25a, 25b via a holder.

  In addition, the fish that has been caught can be stored in the recess 21a by collecting water in the recess 21a by removing the stopper of the recess 21a that has become empty. When swimming, jump into the water from the top of the deck 11b, or take out the ladder 23 from the recess 21b of the housing portion and attach it to the tip of the hull 11 as shown in FIG. You can go underwater. When going out of the water, the ladder 23 may be used to climb on the deck 11b, or it may be climbed directly from the peripheral edge of the deck 11b on the upper surface of the deck 11b.

  In addition, when a wakeboard is attached to the rail portion 25a or the rail portion 25b in advance and the wakeboard is used, first, the wakeboard is removed from the rail portion 25a or the rail portion 25b and the end portion of the rope to be used Is attached to a mounting portion 12 a provided at the rear end of the steering seat base 12. Next, the wakeboard is floated on the water, and one of the occupants gets on the wakeboard with a grip connected to the tip of the rope. Then, another person among the occupants steers and propels the water vehicle 10.

  As described above, when the water vehicle 10 is being propelled, outside air is taken into the engine room from the intake port 16a through the cowl 16 and the flexible hose 19, and at this time, water is taken into the intake air together with the air. Even if it enters the cowl 16 from the mouth 16a, the water is prevented from entering the flexible hose 19. For this reason, water does not enter the engine and the engine drive is not hindered or the engine is not damaged. The deck 11b can also be used as a space for loading various kinds of luggage.

  Furthermore, as another method of using the upper surface of the deck 11b, as shown in FIG. 10, stand-type seats 29a and 29b may be attached to the rear side of the lid 22 of the housing portion in the front side portion of the deck 11b. it can. In this case, a screw hole for attaching a bolt is provided in the deck 11b, a bolt insertion hole is provided in the lower part of the sheets 29a and 29b, and the bolt hole is passed through the bolt insertion hole of the sheets 29a and 29b. The sheets 29a and 29b are fixed to the deck 11b by being screwed together. According to this, not only the seat 13 and the auxiliary seat 14 but also the seats 29a and 29b can be seated and relaxed.

  As described above, in the water vehicle 10 according to the present embodiment, the portion other than the central side portion where the steering seat base 12 is provided on the upper surface of the deck 11b is formed in a substantially flat shape, and therefore, on the upper surface of the deck 11b. The planar portion can be widened. For this reason, the movement range on the upper surface of the deck 11b by the occupant is widened, and the movement is easy. Moreover, since the place where the luggage | load etc. on the upper surface of the deck 11b is put becomes large, when fishing on the water vehicle 10, many box-shaped things, such as a fishing tackle and a cooler box, can be put side by side.

  Further, the planar portion of the upper surface of the deck 11b is formed up to the peripheral edge of the deck 11b, and only the rib portion 24 protruding slightly upward is formed on the peripheral edge. Even if it receives a wave, the water of the wave can be drained from any part of the outer peripheral edge of the deck 11b. For this reason, it is prevented that water accumulates on the deck 11b. Further, when the occupant gets into the water, it can be boarded from any part of the water vehicle 10. In particular, when the occupant gets in from the rear side of the water vehicle 10, it is possible to get in easily by using the reboarding step 28.

  In addition, since the intake port 16a for taking outside air into the engine room is provided in the cowl 16 constituting the front surface of the steering seat base 12, the intake port 16a can be opened toward the traveling direction of the water vehicle 10, This facilitates the introduction of outside air into the engine room. Further, since the intake port 16a is positioned above the upper surface of the deck 11b, even if the water vehicle 10 is subjected to waves and water accumulates on the upper surface of the deck 11b, water enters the engine room from the intake port 16a. It becomes difficult to do.

  Further, a water separation structure for separating air and water entering the intake port 16a and preventing water from entering the engine room is provided with an air flow path directed upward from the intake port 16a into the cowl 16. The flexible hose 19 is configured such that the position of the upper end opening 19a is higher than the intake port 16a. For this reason, even if water enters the intake port 16 a, the water flows below the cowl 16 without entering the flexible hose 19. This can reliably prevent water from entering the engine room.

  Further, since the distance from the front end of the steering seat base 12 to the front end of the hull 11 is longer than the distance from the rear end of the steering seat base 12 to the rear end of the hull 11, The distance to the front end portion of the body 11 is increased, and water is less likely to enter the intake port 16a. Further, since the handrail 18 that can be gripped when the occupant moves on the deck 11b is provided in the vicinity of the steering handle 15 in the upper part of the cowl 16, the occupant can easily move on the deck 11b by grasping the handrail 18. Become.

  Furthermore, since the rail portions 25a and 25b are provided on the front side portion of the peripheral portion of the deck 11b, it is easy to move the occupant on the deck 11b, or when a load is loaded on the deck 11b It is possible to prevent the load from falling. Moreover, since the accommodating part which consists of the accommodation recessed part 21 and the cover body 22 was provided in the front side part in the upper surface of the deck 11b, the ladder 23, an anchor, etc. can be accommodated in the part which becomes a dead space originally. Further, the lower end of the recess 21a of the housing recess 21 is positioned below the draft line of the hull 11, and a water inlet 21c is provided at the lower end of the recess 21a. Since it was made to communicate with the water introduction path which can introduce water into the recessed part 21a from the outside, water can be stored in the recessed part 21a and used as a ginger.

  FIG. 11 shows a water vehicle 10a according to another embodiment of the present invention. In this water vehicle 10a, the handrail 18a is attached horizontally so as to surround the front surface, not the outer peripheral portion of the windshield 17a. The handrail 18a is disposed at a position lower than the steering handle 15c. The configuration of the other parts of the water vehicle 10a is the same as that of the water vehicle 10 described above. Accordingly, the same parts are denoted by the same reference numerals and the description thereof is omitted. Since the water vehicle 10a is thus configured, the handrail 18a does not block the driver's field of view during driving. Other functions and effects of the water vehicle 10a are the same as those of the water vehicle 10 described above.

  Further, the water vehicle according to the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, in the embodiment described above, the rib portion 24 is formed on the peripheral portion of the deck 11b. However, the rib portion 24 is not provided, and the peripheral portion of the deck 11b can be flat. According to this, the drainage of the upper surface of the deck 11b is further improved. Moreover, in embodiment mentioned above, although rail part 25a, 25b part is provided in the front part side part of the peripheral part of the deck 11b, this rail part 25a, 25b part may be abbreviate | omitted, and it is in other parts.
