Description

Description: TECHNICAL FIELD The present invention relates to a storage structure for a small jet propulsion boat that travels 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. On this ship, there is a demand to have a container for storing tools and food, but the space for the container is limited due to the small size of the hull, and water enters due to the low freeboard. Therefore, the conventional structure does not have a proper storage case.

(Object of the Invention) The present invention has been made to solve such a conventional problem, and provides a convenient container for a small hull without changing the basic shape of the hull. It is an object of the present invention to provide a storage structure for a small jet propulsion watercraft.

(Structure of the Invention) In the present invention, the deck member projects upward on the hull centerline to form a seat base, and the upper end of the seat base is bent inward so that a substantially horizontal receiving surface is formed by the bent part. An opening is formed on the inside of this receiving surface, and a container having a substantially horizontal flange at the peripheral edge and projecting downward from the opening and opening upward,
The flange is overlapped on the receiving surface of the seat base so that it is detachably attached to the seat base, and the seat is arranged so that the bottom surface of the seat abuts on the flange of the storage case via packing. The inside of the storage case is constructed in a watertight structure, the propulsion machine is installed under the storage case, the hood decks are formed on both sides of this seat, and the operation handle is installed on the front side of the seat. .

In the above configuration, since the storage space is configured using the dead space under the seat, it is not necessary to change the basic shape of the hull. In addition, an opening is formed on the upper surface of the seat base, and a storage case that covers the opening and projects downward from the opening and opens upward is detachably attached to the seat base. The inside of the hull and the propulsion machine can be inspected. Further, since the packing has a watertight structure with a packing interposed between the edge of the container and the lower surface of the seat, the watertight function of the container is reliably maintained by the lower surface of the seat.

Furthermore, the weight of a heavy load placed in a luggage compartment and the load of an occupant seated on the seat are supported by the seat base through the flange and the receiving surface. Therefore, the above-mentioned load is received on a wide surface, so that even if a heavy object is put in the case or a large load is applied to the seat, it is possible to sufficiently withstand the strength.

(Embodiment) In FIGS. 1 and 2, a hull 100 has a drainage volume in a portion surrounded by a bottom plate 20, an upper deck 21 formed in front of the center of the hull, and a deck member behind the hull. An engine room 29 is formed in a substantially enclosed manner 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. And this foot deck 30 and seat base
The lower side of 55 is also configured to have a drainage volume.

An openable and closable hatch 28, which is a part of the upper deck, is provided in the center of the hull in front of the seat 50. A handle support portion 61 is formed on the hatch 28 in a protruding manner, and a handle 60 is provided at the upper end portion thereof. The hatch 28 is formed so as to project, and an engine room 29 serving as a buoyancy space is formed below the hatch 28. Also, the person 11 on the seat 50 has his foot on the foot deck 30.
The hull 100 is operated by gripping the handle 60 while it is placed on the top, and from this state, the operator 11 can move the 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,
By propelling water backward from the nozzle 34 that swings horizontally in the stern through the flow path 33 formed on the lower side of the seat 50, a propulsive force and a turning force are generated. A fuel tank 15 is installed on the front side of the engine 14.

The seat 50 is constructed as shown in FIGS. That is, the base 55 of the seat rises from the foot deck 30, and the upper end of the seat 55 is bent inward to form a substantially horizontal edge (receiving surface) 56 of the opening. Further, the opening has a substantially horizontal flange 81 at the peripheral edge thereof, and a storage case 80 opening upward is attached.
The storage case 80 has an edge portion (flange) 81 which is superposed on the edge portion 56 and is connected to the edge portion 56 by a bolt 59.
In the seat 50, a bottom plate 51 is attached to the lower surface of a core material 52 made of a plastic foam material and is covered with a sheet 53. A lower plate 54 is attached to the lower surface of the bottom plate 51 and a storage case 80.
The lid for is configured. A packing 70 is attached to the peripheral portion of the lower plate 54, and the packing 70 is attached to the edge portion of the container 80.
The container 80 is closed by a watertight structure by being crimped onto 81.

A hole for inserting a pin 90 provided on the hull is formed at the lower front end of the seat 50, and a locking mechanism 60 as shown in FIGS. 5 and 6 is provided at the lower rear end. It is provided.
The lock mechanism 60 is composed of a U-shaped hook 58 mounted on a mounting plate 57 on the lower surface of the seat and a locking means mounted on the seat base 55.

The locking means is a substrate 65, a guide member 66 mounted on the substrate 65 and having a groove formed in the central portion, and the guide member 66.
66 has a locking piece 62 that moves in the groove, a guide surface 62a is formed on the upper side of the front end of the locking piece 62, and a locking portion 62b is formed on the lower side thereof. A base portion 63 movably fitted in a guide member 66, an operation member 63 projecting to the rear end portion, and an operation member 64 projecting to the rear end portion are attached to the lower portion. A spring 68, which is held by a holding plate 69 and presses the locking piece 62 forward (to the right in FIG. 5), is attached to the rear end of the guide member 66, and a stopper 67 is attached to the upper surface of the guide member 66. Has been.

In the above structure, when the operating member 64 is pulled by hand from the state of FIG. 5, the locking piece 62 retracts (moves leftward in FIG. 5) and the hook 58 disengages from the locking portion 62b. Lifting the rear end of the seat and pulling it backwards will unlock the pin 90 on the underside of the seat 50, which will remove the seat 50 and place it in the storage compartment 80.
Is released. In order to mount the seat 50, first, the pin 90 at the front end is locked, and when the rear end of the seat is lowered by using that part as a fulcrum, the hook 58 is pressed onto the guide surface 62a, so that the locking piece 62 is fixed. The hook 58 is retracted against the force of the spring 68, and the lower end of the hook 58 is guided by the guide member 66 as shown.
When it reaches the upper position, the locking piece 62 is returned by the spring 68, and the hook 58 is locked by the locking portion 62b. Then, in this state, the stopper 58 blocks the backward movement of the hook 58, and thus the closed state of the container 80 is maintained. In this state, the packing 70 is pressure-bonded to the edge of the container 80, so that the container 80 has a watertight structure.

Since the storage case 80 is formed in the lower part of the seat as a dead space in this way, even a small hull does not affect the basic structure of the hull, and the seat 50 has a function as a lid. Can be easily opened and closed, and the function as a storage case can be fully exerted. Further, an opening is formed on the upper surface of the seat base 55, and a storage case 80 that covers the opening and projects downward from the opening and opens upward is detachably attached to the seat base 55. The inside of the hull and the propulsion machine can be inspected by removing 80. Further, since the packing 70 is interposed between the edge 81 of the storage case 80 and the lower surface of the seat 50 to form a watertight structure inside the storage case 80, the watertight function of the storage case is reliably maintained by the lower surface of the seat.

Further, the heavy load put in the storage case 80 and the load of the occupant 11 seated on the seat 50 are supported by the seat base 55 via the flange 81 and the receiving surface 56, but the seat base 55 is formed substantially horizontally and is The above-mentioned load is received on a wide surface through the overlapped flange 81 and the receiving surface 56. Therefore, even if a heavy part is put in the storage case 80 or a large load is applied to the seat 50, the strength is sufficient. Can withstand.

(Effects of the Invention) As described above, in the configuration of the present invention, since the storage space is configured by utilizing the dead space under the seat, it is not necessary to change the basic shape of the hull, and Since the container is formed so as to open on the upper surface of the seat base formed to project upward in the central portion, there is an advantage that water is unlikely to enter the container. Further, since the storage case is supported by the seat base formed integrally with the deck member, the strength against the weight of the stored items in the storage case is very excellent. Further, an opening is formed on the upper surface of the seat base, and a storage case that covers the opening and projects downward from the opening and opens upward is detachably attached to the seat base. The inside of the hull and the propulsion machine can be inspected. further,
Since the packing has a watertight structure with a packing interposed between the edge portion (flange) of the container and the lower surface of the seat, the lower surface of the seat reliably holds the watertight structure of the container.

Furthermore, the weight of a heavy load placed in a luggage compartment and the load of an occupant seated on the seat are supported by the seat base through the flange and the receiving surface. Therefore, the above-mentioned load is received on a wide surface, and therefore, it is possible to sufficiently withstand the strength even if a heavy object in the case is put in or a large load is applied to the seat.
