BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat structure excellent in waterproofness and cushioning property, which is used in small boats and the like.

[0002]

2. Description of the Related Art Conventionally, there are some small boats such as jet propulsion boats gliding on water which are provided with a seat body composed of a cushion body, but these may be wet by splashes of water or rain during traveling. Many. In order to exert a good cushioning property, the cushion material of the seat body discharges air by receiving a compressive force and sucks air when restoring, but when sucking this air, water is absorbed. Will also inhale. In order to prevent this, for example, in Japanese Utility Model Publication No. 53-24799, the cushion material is hermetically sealed with an outer skin and an air bag is connected, and the air discharged by the compressive force is sent into the air bag. It proposes a structure that does not suck in the air.

[0003]

In the above structure, the air bag and the recess for containing the air bag are largely projected to the lower side of the seat body, so that the space below the seat body becomes a dead space. is there. In order to reduce the dead space, it is conceivable to thin the entire cushion material, but doing so may impair the cushioning property.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and it is possible to make the seat body exhibit a good cushioning property and to make a space below the seat body no dead space. It is intended to provide a seat structure for a ship or the like.

[0005]

SUMMARY OF THE INVENTION The present invention is a seat body which is placed on a seat pedestal such as a hull and the outer surface of a cushion material is covered with a watertight outer skin and a bottom plate.
An annular packing is provided between the seat base and the bottom plate of the seat body, and a sealed space is formed below the bottom plate in the hull of the portion surrounded by the packing. The bottom plate is formed with a through hole for ventilation that connects the closed space and the inside of the seat body.

The seat base is formed by projecting the deck upward on the center line of the hull, and a container casing that forms the closed space is fitted into the seat base. The container casing opens upward and the upper end peripheral edge. It is preferable that a flange is formed in the portion, the flange is placed on the peripheral portion of the opening, and the seat body is placed on the flange via the packing.

The cushion material is composed of an upper core material made of open-celled soft plastic foam material and a lower core material made of closed-cell plastic foam material. The lower core material is formed on the bottom plate. A configuration may be used in which a through hole that communicates with the above through hole is formed.

[0008]

In the above structure, the outer surface of the core member is covered with the bottom plate and the outer cover in a watertight structure to form the seat body, and the inside of the seat body communicates with the closed space below. , The air only reciprocates between the inside of the seat body and the closed space, it is possible to prevent the intake of water from the outside, and the seat body has a good cushioning property because the air flows in and out due to the compression force. Can be demonstrated. Further, since the space below the seat body is a closed space, it can be effectively used as a storage case and does not become a dead space.

[0009]

1 to 3, a hull member 11 forming a ship bottom plate and a deck member 12 forming a deck are integrally formed by FRP or the like, and they are joined to each other at a peripheral edge portion 13 to form a hull 1 Is configured. Inside the hull 1, an engine 9 is installed in an engine room 90 on the front side of a partition wall 95, and an impeller 92 that is rotationally driven by the engine 9 is installed at the stern of the water jet 9
By sucking water from the bottom of the ship by rotating in the flow path of 2,
By propelling water from the nozzle 93 at the stern end in a predetermined direction, propulsion and turning forces are generated.

A seat member 6 is formed on the deck above the center line of the hull 1 at the rear of the central portion, and a seat base 6 is formed by recessing both sides of the seat base 6. The outer side thereof is further erected and the gun flannel 5 is formed. The upper edge 6 of this seat base 6
The seat body 3 is placed on the seat body 1, and the operation handle 2 installed on the handle base 60 is provided on the front side of the seat body 3. The handle base 60 is installed on the engine hatch 66 and is attached to the seat body 3. A person who sits down puts his foot on the foot deck 4 and holds the operation handle 2 to drive.

The core material 31 of the seat body 3 is composed of a cushion material formed by molding a continuous foamed soft plastic foam material such as urethane foam into a predetermined shape, and the core material 31 is made of a vinyl sheet or the like. In addition to being covered with a waterproof cover 32, a bottom plate 33 is arranged on the lower surface of the core material 31, so that the outer surface of the core material 31 is covered with a watertight structure. The bottom plate 33 has a flange 37 protruding downward at the peripheral edge thereof, and a through hole 35 is formed at an appropriate position.

An opening is formed inside the upper edge 61 of the seat base 6, and the container casing 8 is inserted into the opening from above. It is mounted on the edge 61. Then, the lower surface of the bottom plate 33 of the seat body 3 is placed on the upper surface of the flange 81 at the upper edge portion via the packing 7, and the bottom surface of the bottom plate 33 is prevented from coming off by an appropriate means (not shown). Sealed to form a closed space. This packing 7 is adhered to the lower surface of the bottom plate 33,
Further, in the installed state of the seat body 3, the flange 37 projecting downward covers the outer peripheral portion of the packing 7 to prevent water from being directly hit on the packing 7.

FIG. 4 shows another embodiment of the present invention, in which the core material of the seat body 3 is an upper core material 36 made of a cushion material formed by molding a continuous foamed soft plastic foam material such as urethane foam into a predetermined shape. And a lower core material 39 made of a closed-cell plastic foam material. Then, a communication hole 38 communicating with the through hole 35 of the bottom plate 33 is formed in the lower core material 39, and the upper core material 36 is formed.
And the inside of the container casing 8 are in communication with each other. Other configurations are the same as those in the above embodiment.

In the configurations shown in FIGS. 2 and 3, a person sits on the seat body 3, puts his / her feet on the foot deck 4, grips the operation handle 2, and drives the hull 1 to run. At this time, a compressive force from above due to the weight of the person is applied to the seat body 3, whereby the air in the core material 31 is discharged into the container casing 8 through the through hole 35,
When the compressive force is released, the air in the container casing 8 is returned to the inside of the core material 31 by being restored by the elasticity of the core material 31, and such an action is repeated, so that good cushioning properties are exhibited. become. The seat body 3
The packing 7 on which is mounted also exhibits some cushioning effect. Also, while the seat body 3 is often splashed with water while sailing, as described above, the air is always in contact with the core material 3.
Since the air is not sucked from the outside only by reciprocating between 1 and the inside of the container casing 8 which is a closed space, it is possible to reliably prevent water from entering the core material 31.

Further, in the above-mentioned structure, since a storage compartment is formed on the lower side of the seat body 3, a dead space does not occur inside the seat body 3, and the space is effectively used. Further, in the configuration of FIG. 4, since the core material is composed of the upper core material 36 that exhibits soft elasticity and the lower core material 39 that exhibits hard elasticity, the elasticity as a whole is relatively hard. As described above, the upper core member 36 allows air to flow between the upper casing 36 and the container casing 8 through the through hole 35 and the communication hole 38, and therefore, the same operational effect as described above is exhibited.

In the above embodiment, only the case where the container is arranged under the seat main body is shown, but if the space is a closed space that does not allow water to enter from the outside, a container other than the container can be arranged. Good. The present invention is not limited to the small boat as shown in the above-mentioned embodiment, but can be similarly applied as long as the seat body may be splashed with water.

[0017]

As described above, according to the present invention, the outer surface of the core member is covered with the bottom plate and the outer cover in a watertight structure to form the seat body, and the inside of the seat body is located below the core body. Since it communicates with the closed space, air simply reciprocates between the inside of the seat body and the closed space.
Intake of water from the outside is prevented, and since the seat body allows air to flow in and out due to the compressive force, the seat body can exhibit good cushioning properties.
Furthermore, since the space below the seat body is a closed space,
It can be effectively used as a storage case and does not become a dead space.
