Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to a small jet propulsion boat that is a single-seater and sails at high speed on the sea.

(Prior Art) In recent years, small jet propulsion boats which are engine-equipped small boats and are designed to slide on water have been widely used. This ship glides on the surface of the water and performs various operations (exercises) such as sudden start and sudden turn. When maneuvering, the operator on the seat stands on both foot decks and leans the hull by moving the weight back and forth, left and right, but at this time the seat should be as small as possible to protect the inside of the operator's knees. It is desirable to extend it in the front-back direction.
On the other hand, a handle and a cover body projecting upward are provided on the front side of the seat. In this case, the locking tool of this cover body is located at the rear end portion of the cover body. A configuration for protection is also required. Then, it is necessary to achieve such various requirements in a small boat body having a limited space.

(Object of the Invention) The present invention has been made to solve such a conventional problem, and is a small jet propulsion boat provided with a function of protecting a locking tool at a rear portion of a cover body in a small boat body. Is provided.

(Structure of the Invention) According to the present invention, a straddle-type seat is formed in the center of the hull in the width direction, operating handles are installed on the front side of the hull, and foot decks are formed on both sides of the seat, and the seat is removable. A deck member that is configured as possible and that is joined to the bottom plate to form the hull front part is composed of an upper deck and a cover body attached to the upper surface of the deck member, and an opening is formed on the upper surface of the upper deck. Is attached to the upper deck upper surface so as to cover this opening,
The cover body extends from the lower rear side to the lower front side of the operating handle, and a locking member of the cover body is provided at a rear end portion of the cover body, and a front end portion of the seat covers the locking body. It is abutted on the rear end of the.

In the above configuration, the locking member at the rear end portion of the cover body is covered and protected by the front end portion of the seat, and the front end portion of the seat is in contact with the rear end portion of the cover body. Receives the force generated as the weight of the occupant moves through the department.
Since this cover body extends from the lower rear side to the lower front side of the operating handle, this force can be received by a wide surface, and its deformation can be suppressed. Further, since the deck member is divided into upper and lower parts and the inside of the boat can be inspected only by removing the upper cover body, it is not necessary to remove the entire deck member for inspection, and the inspection work can be easily performed.

(Embodiment) In FIGS. 1 and 2, a hull 100 includes a ship bottom plate 10, an upper deck 21 formed in front of the center of the hull, and a portion surrounded by a deck member behind the hull 100 as a drainage volume. An engine room that is substantially sealed and is formed in a portion surrounded by the bottom plate 20 and the upper deck 21. A seat 50 is formed so as to project from the center of the hull in the widthwise center of the hull, and a foot deck 30 that opens to the stern end is formed between the seat 50 and the gunnels 88 on both sides. The foot deck 30 and the lower side of the seat 50 are also configured to have a drainage volume.

In the center of the hull, on the front side of the seat 50, an openable and closable hatch 28, which is a part of the upper deck, is provided. The hatch cover 28, which is a cover body, is formed with a handle support portion 61 protruding from the upper end portion thereof. Handle 60 is formed on this hatch 28
The engine room 29 is formed so as to project and is a buoyancy space below the engine room 29. In addition, the person 11 on the seat 50 puts his / her feet on the foot deck 30 and operates the above handle 60.
The hull 100 is gripped to steer the hull 100, and the operator 11 stands up from this state and can move his / her weight back and forth and left and right.

A propeller (not shown) is rotated by the engine 14 in the engine room to suck water from the water suction port 32 at the bottom of the ship,
A turning force and a propulsive force are generated by injecting water backward from a nozzle 34 that swings horizontally in the stern through a flow path 33 formed on the lower side of the seat 50. 15 is a fuel tank.

The base 58 of the seat is formed by rising from the foot deck 30,
The seat 50 is removably attached to the upper end of the seat 50 through packing 70 by appropriate locking tools 60 and 90. The packing 70 is for sealing the storage case 80 formed in the lower portion of the seat, and therefore, it is not necessary to provide the storage case 80 when the storage case 80 is not formed.

On the front side of the seat 50, a hatch cover 28 of the engine room 29 extends from the rear lower side of the handle 60 to the lower front side and is formed so as to project upward. The hatch cover 28 is opened and closed by a hinge 51 at its front end portion. It is mounted on the hatch combing 27 of the deck 21, and a locking tool 52 for holding the closed state is mounted on the rear end portion. A locking tool 53 for locking the locking tool 52 is attached to the rear side of the hatch combing 27 of the upper deck 21.

A front wall 56 of the seat is recessed at the front end of the seat 50 and a recess 57 is formed on the front side thereof.
2,53 is located. That is, when the seat 50 is attached, the locks 52 and 53 are covered by the seat 50, and are not exposed to the external force from the operator 11 or the like moving on the seat and cannot be seen from the outside. Both sides of the recess 57 are
An extension portion 55 is formed by extending a side portion of the seat 50, and the extension portion 55 is configured to contact the side surface of the hatch cover 28 and the upper deck 21 below the hatch cover 28. Just like the seat 50, an appropriate cushion material may be filled inside the extension portion 55.

In the above structure, the seat 50 is attached and detached in the vertical direction by the fasteners 60 and 90. Then, with the seat 50 removed, the latches 52, 53 are unlocked, and the hatch cover 28 is rotated around the hinge 51 to open as shown by the phantom line in FIG.
Work such as repair of the engine 14 is performed through the opening formed by the hatch combing 27. Further, after closing the hatch cover 28, the seat 50 is lowered from above and attached by the fasteners 60, 90, and the fasteners 52, 53 are located in the recess 57 formed by the front wall 56 and extended. The portion 55 comes into contact with both sides of the rear portion of the hatch cover 28. Therefore, when the driver 11 sits on the seat 50 and moves his / her weight forward while driving, the inside of the knee hits the extension 55, and the knee is protected.

In this way, the front end of the seat 50 protects the locking member of the hatch cover 28 that can be opened and closed, and the extensions 55 on both sides of the front end of the seat 50 protect the knees of the operator 11. .

(Effects of the Invention) As described above, in the configuration of the present invention, the locking member at the rear end of the cover body is covered and protected by the front end of the seat, and the front end of the seat is located at the rear end of the cover body. Due to the contact, the cover body receives a force generated as the weight of the occupant moves through the front end of the seat. Since this cover body extends from the lower rear side to the lower front side of the operating handle, this force can be received by a wide surface, and its deformation can be suppressed. Further, since the deck member is divided into upper and lower parts and the inside of the boat can be inspected only by removing the upper cover body, it is not necessary to remove the entire deck member for inspection, and the inspection work can be easily performed.
