Description

Description: TECHNICAL FIELD The present invention relates to a deck structure of a small planing watercraft that rides on a deck and grips a steering wheel to travel.

[Conventional technology]

This type of small planing boat has high speed and excellent maneuverability.As a conventional hull structure, for example, an engine is mounted in an engine room formed inside the hull and a propulsion unit is installed at the rear of the bottom of the hull. A structure has been adopted in which the outboard motor is attached to the rear part of the hull, and the steering wheel attached to the front part of the deck is gripped for steering.

Both the deck and hull are generally made of plastic (FR
Propeller or water jet propulsion machine is used as the propulsion machine. In the case of water jet propulsion machine, steering by changing the direction of the injection nozzle (steering handle) to the left or right. You can

Further, the rear deck structure is a fin type in which fin portions projecting upward on both sides are formed and a riding floor for riding in a standing posture is mainly formed between the fin portions, or a saddle projecting upward in the center portion. For example, a riding seat type in which a seat portion of a mold is formed and step portions are formed on both sides of the seat portion is adopted.

In addition, in this type of small planing boat, it often rides from the water, in which case it is common to get on the handle and climb up from the rear of the deck.

In FIG. 7, an opening 29 is formed on the upper surface of the armrest 14.
The elbow pad 15 is attached to the armrest so as to be rotatable about the hinge 30 between an open position indicated by a chain double-dashed line and a closed position shown in the drawing.

The operation lever 28 is provided inside the armrest 14.
Are rotatably supported about a shaft 31. A knob 32 is attached to the tip of the operation lever 28. By rotating the operation lever 28 in the direction of arrow A, the arm portion 33 at the other end is rotated in the direction of arrow B, and the arm portion 33 is rotated. The tilt angle (vertical tilt) θ of the tilt nozzle 35 of the water jet propulsion device 21 can be adjusted via the control cable 34 connected to the tip.

The elbow pad 15 is openably and closably attached to the armrest portion 14 formed in a part of the gunnel, and the elbow pad 1 is provided in the armrest portion 14.
5 is provided with an operation lever 28 for adjusting the tilt angle of the water jet propulsion device 21 provided at the rear of the ship bottom or opening / closing the lid 19A of the trunk room 19 provided at the deck rear 17 (FIG. 1). Is configured to do.

With such an open / close-type elbow pad 15, the operation lever 2
The structure for covering 8 is provided on either the left or right side or both sides.

The water jet propulsion device 21 is connected to the engine 20.
A propeller (rotary blade) 37 and a stator (fixed blade) 38 which are rotationally driven by a shaft 36 (see FIG. 3).
A duct 39 for accommodating the propeller 37 and the stator 38 to form a cylindrical water flow path, a steering nozzle 40 rotatably attached to the rear end of the duct 39 so that the steering nozzle 40 can rotate right and left, The tilt nozzle 35 is attached to the end of the nozzle so as to be vertically rotatable. The propeller 37 applies backward kinetic energy to the water coming from the water inlet 42 of the ship bottom, and each nozzle 4
It is configured to receive propulsive force by being injected from the stern through 0 and 35.

In this case, the steering handle 10 (FIGS. 1 to 3) is rotated to control the left-right direction angle of the steering nozzle 40 via a link mechanism or a control cable (not shown). (Steering) is possible.

Further, the vertical angle (tilt angle) θ of the tilt nozzle 35
The angle of attack of the hull 1 during traveling can be controlled by adjusting.

Although FIG. 7 exemplifies the operation lever 28 for adjusting the tilt angle θ of the water jet propulsion device 21, instead of this,
Alternatively, together with this, a lid 19 of the trunk room 19 is provided as an operating lever provided in the armrest 14 on the opposite side.
An operation lever for opening and closing A can be similarly arranged.

According to the embodiment described above, the following operational effects can be achieved.

Since the steering wheel 10 projectingly arranged above the floor 6 is grasped for steering, the livability at the time of traveling can be improved not only for one passenger but also for two passengers. We obtained a small planing boat that allows us to enjoy leisure travel even more.

(ii) Since the gun flannel on both sides of the small planing boat 6 is lowered to provide the entrances / exits 16 and 16 and the knee pads 22 are joined to the lower surface of the entrances / exits 16 and 16, the dive into the water and the deck from the water The deck structure of a small planing boat that was easy to get on was obtained.

(iii) Also, the cockpit floor 6 is provided on the front part 7 of the deck.
Since the protruding portion 8 projecting above is formed and the steering handle is attached to the steering shaft 9 which is rotatably supported in the protruding portion 8, the cockpit floor 6 can be sufficiently wide and the operation can be improved. The habitability of passengers and passengers could be further improved.

(iv) Further, since the armrest portions 14 are formed at positions corresponding to both sides of the bench seat 5 of the gun flannel portion, and the elbow pad 15 is provided on the upper surface of the armrest portions 14, the comfortability during traveling can be further improved. did it.

(v) Since the drain ports 26 leading from the cockpit floor 6 to the outside of the hull are provided in the deck sidewalls on both sides of the cockpit floor 6, even if water enters the cockpit floor 6, this should be drained immediately. I was able to.

(vi) Since the grip 23 is provided on the side surface of the projecting portion 8 of the deck front portion 7, the grip 23 can be used when getting on the deck from the water.
A deck structure was obtained in which it was possible to support the body by grasping the knee pad and holding the knee pad on the knee pad and supporting the body.

(vii) The elbow pad 15 is attached to the armrest portion 1
4 is attached to be openable and closable, and an operating lever 28 covered with the elbow pad 15 is provided in the armrest portion 14 to adjust the tilt angle of the water jet propulsion device 21 or open / close the trunk lid 19A. Since it is configured so that it can be carried out, the operating lever 28 can be installed without requiring an extra space, in a sealed state near the seat and in a state where the elbow pad 15 is opened and can be easily operated.

As the steering handle 10, a round handle, a bar handle, or the like can be freely used in addition to the concave-shaped handle as illustrated.

Further, the width of the projecting portion 8 protruding from the deck front portion 7 to the upper side of the cockpit floor 6 can be freely selected, and in some cases, it may be as wide as the width of the deck. can do.
