Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to an improvement of a steering handle device for a small jet-propelled watercraft.

<Conventional technology and its problems> In general, in small jet-propelled boats that glide freely on the water surface, one operator stands on the floor deck of the boat and holds the boat with both hands. By turning the handlebar, you can control the steering cable that runs from the handle post through the inside of the boat to the stern, and swing the steering cable of the jet propulsion device installed at the stern left and right. It is designed to be moved and steered, but in the conventional boat, the eighth
．． As is clear from Figure 9, the middle grip part (C) of the pair of left and right handlebars (b) that protrudes from the upper rear end of the handle post (a) has an overall V-shaped horizontal shape when viewed from the top. The array is installed in the state.

Therefore, when the boat body (d) turns, the operator holding the grip part (e) is moved sideways.
The pilot's body will be swung around, and the meaning and power of the
This forces the driver into an extremely unstable control position, making it impossible to operate smoothly and stably. In addition, since both sides of the body are held in a gripping position, it is not possible to apply the treading force due to the body weight to the boat body (d) effectively and as desired due to ergonomics, and the so-called quick steering performance is impaired. There are other problems as well.

<Means for Solving the Problems> The present invention is intended to solve these various problems, and for this purpose, a base plate for mounting the handle is attached to the upper rear end of the handle post that stands up from the hull. In a jet propulsion type small watercraft, the handlebar mounting plate is fixedly installed, and the handlebar mounting plate, which exhibits a widening V-shape as a whole when viewed from above, is rotatably supported on the base board by a vertical axis, A pair of handle grips are attached to both the left and right ends of the handlebar so as to stand up on a plane perpendicular to the installation plane of the bar, and to rotate in the front and back direction about the longitudinal axis of the bar.
The first feature is that the mounting plate is adjustable in its undulation angle with respect to the installation plane.Also, based on the premise that the steering wheel device is used for the same jet-propelled small boat, the above-mentioned mounting plate is connected to the front plate that is pivoted to the base plate. , and a rear plate integrally provided with the handlebar, and the pair of plates are connected so as to be freely adjustable in the front and rear directions, and a pair of handle grips are attached to both left and right ends of the handlebar. , stands on a plane perpendicular to the installation plane of the bar, and rotates in the front and back direction around the longitudinal axis of the bar,
The second feature is that the mounting angle with respect to the installation plane can be adjusted.

<Example> Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated example. In FIG. The hull is made of a material such as RP) and has a completely hollow, sealed float structure, and almost the rear half of the hull is defined as a floor deck (11) on which the operator stands. (12) is the engine room configured in the remaining front half, and (13) is the same (handle post that is pivoted to the bow of the hull (10) by a horizontal axis (14) so that it can be raised and lowered around it. Yes, that floor deck (11
), a base plate (15) for mounting the handle is fixedly and integrally supported from below.

The following control handle device is assembled to the base board (15). That is, in Figures 2 to 6, which are extracted and enlarged, (16) is the handlebar (1
7), and the front plate (16a)
and a rear plate (16b), and
A handlebar (17), which has a rearwardly widening V-shape in plan view, is fixedly installed at the rear end of the rear side play 1- (16b) by welding or the like.

Further, the forward folding plate (16a) is joined to the base board (15) from below and is pivotally mounted around a vertical shaft (18) so that it can be steered around the vertical shaft (18). Its vertical axis (18
) lies on the center line (Y-Y) of the hull 10), but there is also a steering cable (19 ) is attached. Needless to say, the terminal end of the cable (19) is connected to the steering nozzle (not shown) in the stern of the boat via the handle boss (13) and the inside of the boat body (10).

(20) are adjustment screw holes provided in a plurality of open rows in pairs on the left and right sides at the rear end of the front plate (16a);
A plurality of sets of adjustment holes (21) matching this are formed correspondingly at the front end of the rear play 1- (16b).

Therefore, by replacing and screwing the fixing pole (22) from the hole (21) to the screw hole (20),
The rear plate (16a) is relative to the front plate (16a).
The connection position of b) can be adjusted in a so-called telescopic manner. In other words, the handlebar (17) attached to the rear plate (16b) can be adjusted to be long or short according to the length (mounting position) (L) that extends rearward from the vertical axis (18). That's why.

However, the installation play 1- (16) of the handlebar (17)
) is a pair of front and rear plates (16a) (1
6b), but it is also possible to create it as a continuous integral piece thereof. In addition, (23) is a notch that defines the rotation angle of the mounting plate (16) with respect to the vertical axis (18), and the forward tilting plate (16a)
It is attached to the front edge of. It is also suggested by the park that (22) exists in multiple pairs, one on the left and one on the left.

The handlebar (17) is made of a round metal pipe material, and male splines (24) and male threads (25) are carved in parallel on the surfaces of both left and right ends thereof. On the other hand, (2
6) is a pair of left and right handle grips that are separate from the handlebar (17), and are also made of a metal round vibe material of a certain length, with a sheath shaft ( 27) are integrally welded in a penetrating state that intersects perpendicularly, and the male spline (27) is attached to the sheath shaft (27).
A female spline (28) is also cut out for mating action with 4).

The sheath shaft (27) of the grip (26) is spline-fitted to the handlebar (17) so that it can be freely inserted into and removed from the handlebar (17). Fixing nut (29) screwed in from the outside
) is fixed and locked so that it cannot be rotated or removed.

In other words, as is clear from Fig. 5.6, the grip (26) stands upright in a plane perpendicular to the installation plane (X-X) of the handlebar (17), and its male spline (2
By changing the fitting position of the female spline (28) with respect to the handlebar (17), the grip (26) rotates in the front-rear direction about the longitudinal axis of the handlebar (17).

This means that it is now possible to adjust.

However, if the configuration is such that the undulation angle (θ) can be adjusted, for example, the seventh
As shown, the surface of the handlebar (17) and the grip (
The sheath shaft (27) and the sheath shaft (26) may be formed into a polygonal or other uneven cross-section that can be replaced with each other. Also, the sheath shaft (27) and the grip (26) can be made into one continuous piece.

Furthermore, the park has set the grip (26) in a horizontal T-shape that intersects with the handlebar (17) when viewed from the front and back direction of the boat (10), but by making it shorter, By attaching a sheath shaft (27) to one end, it can also be mounted in an L-shape that intersects with the handlebar (17). Note that (30) is a washer, and (31) is a grip (26). It is an end cap, and its grip (26) may be integrated with an elastic coating made of rubber, synthetic resin, etc. (not shown).

<Effects of the Invention> In any case, in the present invention, a base plate (15) for attaching the handle is fixedly installed on the upper rear end of the handle post (13) that stands up from the boat body (10), and The handlebar (17
