JPS62125983A - Container structure for small jet propulsion vessel - Google Patents

Abstract

PURPOSE:To provide a water-tight container without modifying the basic profile of a vessel by forming a container opening upward at the underside of a seat, constructing the seat dismountably to serve as a cover for the container and placing a packing on the underface of the seat to achieve a water-tight structure. CONSTITUTION:Upon pulling of an operating member with hand, a hook in an engaging mechanism 60 is disengaged, the rear end of a seat 50 is pulled rearward while lifting, then a pin 90 at the lower front end section of the seat 50 is disengaged so that the seat 50 is dismounted to open a container 80. When fixing the seat 50, the pin 90 at the front end section is engaged to lower the rear end section of the seat around said point, engaging a hook in the engaging mechanism 60 with an engaging section. Since a packing 70 is fitted with pressure at the edge section of the container 80 under said condition, the container 80 will be water-tight. Since the container 80 is constructed while utilizing the dead space at the lower section of the seat, modification of the basic profile of vessel is not required.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a small jet propulsion boat that is primarily a single-person boat that sails at high speed on the sea.

(Prior Art) Recently, small jet propulsion boats, which are small boats equipped with engines and are designed to glide on water, have come into widespread use. There is a demand for this ship to be equipped with storage compartments for storing tools, food, etc., but the small size of the hull limits the space for storage, and the low freeboard makes it difficult to install storage compartments. There are restrictions such as the fact that water easily enters and the structure must be watertight, and for this reason, the conventional structure did not have an appropriate storage space.

(Purpose of the Invention) The present invention was made to solve such conventional problems, and provides a storage container with a watertight structure that is convenient for use in a small boat without changing the basic shape of the boat. The present invention provides a storage compartment structure for a small jet propulsion boat that avoids the above.

(Structure of the Invention) The present invention provides a small jet propulsion boat in which a seat is formed on the hull centerline on the rear side of the center of the hull, a food deck is formed on both sides between it and the side deck, and a seat is provided on the hull centerline. A storage compartment opening upward is formed on the lower side, and a seat is configured to be removable, and the seat forms a lid for the storage compartment, and a gasket is attached to the underside of the seat along the edge of the opening of the storage compartment. The container is constructed with a watertight structure.

In the above configuration, since the dead space under the seat is used, there is no need to change the basic shape of the hull, and the bottom surface of the seat ensures a watertight structure, and the seat can be easily opened and closed by attaching and detaching it. What can you do?

(Example) In FIGS. 1 and 2, the hull 100 has a bottom plate 20
The area surrounded by the upper deck 21 formed on the front side of the center of the hull and the deck member behind it is configured to be a drainage volume, and the bottom plate 20 and the upper deck 21
A substantially sealed engine room is formed in the area surrounded by. Further, a seat 50 is formed to protrude at the center in the width direction on the rear side of the center of the hull, and this seat 50
A hood deck 30 that opens to the stern end is formed between the gunwales 88 and the gunwales 88 on both sides. The lower side of the hood deck 30 and the seat base 55 is also configured to have a drainage volume.

In the center of the hull, in front of the seat 50, there is a hatch 28 that can be opened and closed and forms part of the upper deck.
A handle support part 61 is formed to protrude, and a handle 60 is formed at the upper end of the handle support part 61, and the hatch 28 is formed to protrude, and an engine room 29 serving as a buoyancy space is formed in the lower part of the hatch 28. In addition, the person 11 on the seat 50 places his or her feet on the food deck 30 while holding the handle 6.
The operator 11 controls the boat 100 by grasping the handle 0, and from this state, the operator 11 can shift his weight back and forth and left and right.

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

15 is a fuel tank.

The portion of the seat IM50 is constructed as shown in FIGS. 3 to 6. That is, the base 55 of the seat is the food deck 30.
The upper end is bent to form the edge 56 of the opening.
is formed. A storage container 80 that opens upward is attached to the opening, and its edge 81 is connected to the edge 5.
6 and connected with bolts 59. seat 5
0, a bottom plate 51 is attached to the lower surface of a core material 52 made of plastic foam material, etc., and is covered with a sheet 53, and a lower plate 54 is attached to the lower surface of the bottom plate 51, forming a lid for a storage compartment 80. has been done. A gasket 70 is attached to the peripheral edge of the lower plate 54, and the gasket 70 is crimped onto the edge 81 of the storage compartment 80.
0 is closed with a watertight structure.

At the lower front end of the seat 50 is a bin 90 provided in the hull.
A locking mechanism 60 as shown in FIGS. 5 and 6 is provided at the lower rear end. The locking mechanism 60 consists of a U-shaped hook 58 attached to a mounting plate 57 on the underside of the seat, and a locking means attached to the base of the seat. This locking means is the base plate 65.
It has a guide member 66 that is attached to this substrate 65 and has a groove formed in the center, and a locking piece 62 that moves in the groove of this guide member 66. A locking portion 62b is formed on the lower side of the guide surface 62a1, and a base portion 63 that is movably fitted into the guide member 66 and an operating member protruding from the rear end are formed at the bottom of the locking piece 62. 64 is attached. A spring 68 is attached to the rear end of the guide member 66 and is held by a retaining plate 69 to press the locking piece 62 forward (rightward in FIG. 5), and a stopper 67 is attached to the upper surface of the guide member 66. It is being

In the above configuration, when the operating member 64 is pulled by hand from the state shown in FIG. 5, the locking piece 62 moves backward in the left direction in FIG.
l) Since the hook 58 is released from the locking part 62b, when the rear end of the seat 50 is lifted and pulled backward, the lock of the bin 90 at the lower front end of the seat 50 is released, and the seat 50 is thereby released.
is removed and the storage compartment 80 is opened. To attach the seat 50, first lock the pin 90 at the front end, then lower the rear end of the seat using that part as a fulcrum.The hook 58 is pressed onto the guide surface 62a, and the locking piece 6
2 is moved backward against the force of the spring 68, and the hook 58
When the lower end reaches above the guide member 66 as shown, the locking piece 62 is returned by the spring 68 and the hook 58 is locked by the locking portion 62b. In this state, the hook 58 is prevented from moving backward by the l-flange 67, so that the closed state of the storage compartment 80 is maintained. In this state, the gasket 70 is pressed onto the edge of the storage compartment 80, making the storage compartment 80 watertight.

In this way, since the storage compartment 80 is formed under the seat, which is a dead space, it does not affect the basic structure of the hull even if the hull is small, and the lid can be easily opened and closed. Since it also has a watertight structure, it can fully function as a storage container.

(Effects of the Invention) As explained above, in the configuration of the present invention, since the dead space under the seat is used to configure the storage space, there is no need to change the basic shape of the boat, and the bottom surface of the seat is A watertight structure is ensured, and the storage compartment can be easily opened and closed by attaching and detaching the seat.
