Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small jet propulsion boat that sails at high speed on the sea.

[Conventional technology]

2. Description of the Related Art Recently, small jet propulsion boats, which are small boats equipped with an engine and run on water, have been widely used. This boat glides on the water surface and performs various operations (exercises) such as sudden start and sharp turn. Therefore, if there is no skill of the operator, the ship will overturn and fall. After the water falls, the pilot re-embarks on the boat, but requires some assistance when climbing from underwater to the hull. However, in this kind of small hull, if a projection is formed on the hull, it will be an obstacle for a rapidly moving operator,
There is also a restriction on the mounting position from a functional aspect.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and enables a passenger who has fallen in water to easily re-board, without disturbing the pilot, and propelling a small jet propulsion. It is an object of the present invention to provide a small jet propulsion boat that does not impair the function of the boat.

[Means for solving the problem]

According to the present invention, a pair of right and left standing walls extending in the length direction of the hull and a rear wall extending in the hull width direction so as to connect the rear ends of the standing walls are formed by projecting the deck member upward on the hull center line. In a small jet propulsion boat having a seat portion having a pair of left and right foot decks formed on both sides of the seat portion, and an outer end of the foot deck projecting upward to form a bulwark, the standing wall of the seat portion is provided. A handle is provided at a position where a passenger sitting on the seat can take a hand, and a handle for the hand is provided on the hull inside the standing wall around the hand. It is formed so as to be recessed.

In the above configuration, a handle is provided on both side standing walls of the seat section formed inside the foot deck, and this is installed at a position where the passenger sitting on the seat section can reach, so that the passenger holds the posture during sailing Can be used to In addition, the handle part for hanging the hand formed on this handwork,
Because it was recessed inside the hull than the standing wall around the handle,
The advantage that the amount of protrusions protruding outside the hull from the surrounding standing wall can be reduced, and when a passenger moves on the foot deck, the effects can be prevented from getting in the way and the weight can be easily moved. There is.

〔Example〕

In FIGS. 1 to 3, the hull 10 includes a bottom plate 20 and a side plate.
A portion surrounded by the upper deck (deck member) 21 and the stern plate 70 formed on the front side of the hull 80 and the hull is configured to have a drainage volume, and is surrounded by the bottom plate 20 and the upper deck 21. A substantially closed engine room is formed in the portion. In the rear part, a seat 50 is formed so as to protrude in the center part in the width direction of the boat, a foot deck 30 is formed on both sides of the seat 50, and a deck wall 89 on which both side deck members of the foot deck 30 protrude upward. A bulwark 88 is formed by the ship side plate 80. The foot deck 30 and the lower side of the seat 50 are also configured to have a drainage volume.

An upper deck 21 inside the foot deck 30 (on the hull center line side) protrudes upward to form a seat portion. The seat portion has an inverted U-shaped base having a transverse cross-sectional shape that is extended upward, and a seat 50 made of a cushion material or the like installed on the base. Handles 40 are attached to standing walls 55 (standing walls on the side of the foot deck 30) 55 on both sides of the seat portion. As shown in FIGS. 4 to 6, the handle 40 comprises an annular flange 41 and a main body 42 inside the flange 41.
The main body 42 has a concave portion 43 and a protrusion 44 formed by an edge of the concave portion (hand-holding portion) 43. The handle 40 is attached to an opening 56 formed in the upright wall 55 by a screw 45 at a flange 41 in a watertight structure.

A handle support 61 is formed on the upper deck 21 so as to protrude, and a handle 60 is formed at an upper end thereof. The deck 21 where the handle support 61 is provided is formed so as to protrude, and a buoyancy space is formed therebelow. An engine room is formed. The operator 11 on the seat 50 drives the hull 10 by gripping the handle 60 with his feet on the foot deck 30.

The propeller (not shown) rotates by an engine in the engine room to suck water from a water suction port at the bottom of the hull, and passes through a flow path formed below the seat 50, from a nozzle 71 that swings in the horizontal direction at the stern. Is injected rearward to generate a turning force and a propulsion force.

In the above configuration, when the person 11a underwater climbs on the hull 10, as shown in FIGS. 2 and 5, the hand 12 is reached from the water to lock the hand 12 to the handle 40, and this is used as a clue. You only have to go up. In the case of a two-seater, the person 11a who has ridden on the rear seat can also hold the body by putting his / her hand on the handle 40 over the seat 50. In the above configuration, the handle 40 has an inner end located inside the outermost surface of the upright wall 55 so that the outer surface of the handle 40 and the outermost surface of the upright wall 55 are located substantially on the same plane. Opening 56 of standing wall 55
To the surface of the standing wall 55 (outermost surface)
Hardly protrude from the foot deck 30, so that there is no hindrance when the operator 11 moves on the foot deck 30. Furthermore, the handle 40 of the hull 10 is located near the center in the width direction,
Even when a person applies a force to the handle, the lateral stability is maintained because no large lateral tilt force is applied to the hull, and the handle 40 is not directly affected by the waves when sliding. Therefore, there is no problem of increasing the propulsion resistance. Also, because the handle 40 is composed of a separate member from the hull 10,
When forming the hull 10, there is no problem of forming a draft for forming the handle 40, so that the production of the hull does not become difficult, and the handle 40 is freely formed so as to be easy to handle. Can be designed.

〔The invention's effect〕

As described above, according to the present invention, a handle is provided on both side standing walls of the seat portion formed inside the foot deck, and this is installed at a position where a passenger sitting on the seat portion can reach the hand. It can be used by passengers to maintain their posture. In addition, since the handle portion formed on the handle for hanging the hand is recessed inside the hull from the standing wall around the handwork, it is possible to reduce the amount of the handwork protruding outside the hull from the surrounding standing wall. It is possible to prevent a passenger from getting in the way when a passenger moves on the foot deck, and there is an advantage that the weight can be easily shifted.
