Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to improvements in steering handle devices for various watercraft.

<Conventional technology and its problems> For example, in a jet-propelled small boat that glides freely on the water surface, one operator stands on the floor of the boat and holds the handle with both hands. By rotating the lever, you can control the steering cable that is routed from the handle post through the inside of the boat to the stern, and swing the steering nozzle of the jet propulsion device installed at the stern in the left and right directions. However, in the conventional watercraft, as is clear from Figures 7 and 8, a pair of left and right handlebars b protrudes from the upper rear end of the handle post a.
In particular, the grip portions c are arranged horizontally in an overall "V" shape when viewed from above.

Therefore, when the boat body d turns, the operator's body is swung around as if the operator's hand holding the grip part c is being carried sideways, which makes the operation posture extremely unstable. If you are forced to do so, you will not be able to operate the vehicle smoothly and stably.
Also, since the grip position opens both sides of the body,
Ergonomically, it is not possible to apply treading force due to body weight to the boat body d effectively and as desired, and there is a problem that the so-called quick steering performance is also inferior.

<Means for solving the problems> In order to solve these problems, the present invention has the following features:
As a control handle device for jet propulsion type boats and other types of watercraft, a base for attaching the handle is fixedly installed at the upper rear end of the handle post that stands up from the hull, and a pair of left and right handle stays are attached to the base from the base. The front end of the handlebar is attached to both the left and right ends of the handlebar mounting plate, which is integrally protruded into an almost "V" shape when viewed from above, and which is rotatably pivoted to the base base on a vertical axis. They are each pivotally connected by joint lights, and the rear end of the handlebar and the rear end of the handle stay are respectively pivotally connected by the handle grip in the upright state, and both grips can be raised and lowered in the front and rear directions. The present invention is characterized in that the handlebar mounting plate is configured to rotate when the handlebar mounting plate is rotated.

<Example> Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated example. FIG. The boat body is made of a material such as fiber-reinforced plastic FRP and has a completely hollow, sealed float structure, and the stern of the boat is defined as a floor 11 on which the operator stands. 12
13 is a handle post pivoted to the bow of the boat by a horizontal shaft 14 so as to be able to raise and lower the engine; for,
A base 15 for attaching the handle is fixedly installed in a backing state.

The following control handle device is attached to the base 15. That is, in FIGS. 2 to 5 extracted from this, reference numeral 16 denotes a pair of left and right handles extending diagonally rearward from both rear ends of the base 15 so as to form an overall substantially "V" shape when viewed from above. Each of the front ends of the stay is joined to the base 15 from below, and is fixed and integrated with a plurality of bolts 17, rivets, or the like.

In that case, it may be possible to fix it by welding means instead of bolts 17 or rivets, but by arranging a large number of mounting holes for bolts 17 in advance, the center line of travel of the hull 10 can be fixed. (Y-
the overhang angle of the stay 16 with respect to Y),
It is preferable to set the overhang length (mounting position) so that it can be changed. 18 is the above stay 1
This is a connecting piece that extends from each rear end of 6.

Further, reference numeral 19 denotes a handlebar mounting plate rotatably mounted on a vertical axis 20 so as to be placed on the upper surface of the base 15, and the vertical axis 20 is aligned with the center line of the boat 10 ( Y-Y) facing above.
21 is a steering cable whose starting end is connected to the mounting plate 1 by means of a ball joint 22.
9, and the terminal end thereof is also connected to a steering nozzle (not shown) in the stern portion of the boat via the handle post 13 and the inside of the boat body 10.

Reference numeral 23 designates a pair of left and right handlebars that extend diagonally rearward from both left and right ends of the mounting plate 19 so as to have an overall approximately "V" shape when viewed from above, and preferably their working lengths are Consists of telescoping adjustable turnbuckles. Each front end of the bar 23 is pivotably attached to the mounting plate 19 by a ball joint 24. 2
5 is a collar inserted into the gap between the ball joint 24 and the mounting plate 19.

Further, reference numeral 26 denotes a pair of left and right handle grips, each of which has a bifurcated connecting piece 27 at its upper end that is pivotally connected to the rear end of the handlebar 23 by a ball joint 28. Similarly, the two-pronged connecting piece 29 at each lower end is pivotally connected to the connecting piece 18 at the rear end of the handle stay 16 by a substantially horizontal horizontal shaft 30 so as to be freely rotatable in the front-rear direction. has been done. In other words, each handle grip 26 is installed in an upright state so as to pivotally connect the handle bar 23 and the handle stay 16 which face each other in a vertical positional relationship. As suggested by the illustration, the ball joints 24, 28 located at the front and rear ends of each handlebar 23 are arranged with axes of action substantially perpendicular to each other.

<Function> Therefore, according to the operating handle device configured as described above, while gripping and holding the handle grip 26 in the upright state with the operating hand, the handlebar mounting plate 19 can be moved along its vertical axis by raising and lowering the wrist. 2
It can be rotated around the fulcrum of 0, and the boat body 10
You will be able to control the

That is, as illustrated in FIG. 6, the pair of left and right handle grips 26 have their lower ends aligned with the horizontal axis 3.
Since it is designed to be able to rise and fall around 0, as you tilt your right wrist, which you are currently holding, forward,
When the left wrist is raised backwards, the handlebar 23 on the right side moves forward, and conversely, the handlebar 23 on the left side moves backward, causing the handlebar mounting plate 19 to move counterclockwise. As a result, the boat body 10 is steered and turned accordingly.

In that case, if the operating length of the handlebar 23 is set to be adjustable as described above, the handlebar grip 26 pivotally connected thereto
This makes it possible to change the standing angle of the vehicle, which is more effective in improving its maneuverability.

Furthermore, in the case of the illustrated example, the handlebar mounting plate 19 is placed on the top surface of the base 15, and the handlebar 23 is disposed above the handlebar stay 16. As long as motion can be generated, the vertical positional relationship may be reversed. It goes without saying that the present invention can be applied not only to jet propulsion type small boats but also to motor boats and other various boats.

<Effects of the Invention> As described above, in the boat control handle device according to the present invention, the base 15 for attaching the handle is fixedly installed at the upper rear end of the handle post 13 that stands up from the boat body 10 due to its structure. , a pair of left and right handle stays 16 from the base 15,
The handlebar 23 is protruded and integrated into an approximately "V" shape when viewed from above, and the handlebar 23 is attached to both left and right ends of the handlebar mounting plate 19, which is rotatably pivoted to the base 15 by a vertical shaft 20. The front ends are each pivotally connected by a ball joint light 24, and the rear end of the handlebar 23 and the rear end of the handle stay 16 are pivotally connected by a handle grip 26 in an upright state. Since the handlebar mounting plate 19 is set to rotate when the grip 26 is raised or lowered in the front-rear direction, all of the problems of the prior art described at the beginning can be solved.

In other words, since the pair of left and right handle grips 26 are pivotally connected to the handle bar 23 and the handle stay 16 so that they can be moved up and down in the front and rear directions, the grips 26 can only be operated by the wrists of the operating hand holding the grips 26. , the boat 10 can be steered stably and easily, and in this position, both sides of the body are kept tight, and the body does not swing around when turning. Furthermore, since the wrist of the operating hand holding the grip 26 is in an erect state, it is possible to effectively apply the force of the body weight to the boat body 10 and to smoothly shift the body weight. Therefore, it can be said that it is useful as a handle device for various types of watercraft, including jet-propelled watercraft that are operated while standing.
