Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a steering device for a small planing boat equipped with a slide mechanism used for moving a handle, a seat, or the like to change its position.

[Prior Art] For example, as a slide mechanism for changing the position of a steering wheel of a small planing boat, there is a slide mechanism described in Japanese Utility Model Laid-Open No. 2-42899. This is constructed so that the slider is arranged in the width direction of the hull and sandwiches the guide member so that the opposite sides of the U-shaped section of the slider are slidably contacted and movable, and the steering shaft is attached to the slider. The position of the steering wheel can be changed. Further, the guide member is provided with a mechanism for forming a long hole in the longitudinal direction, mounting the clamp bolt on the slider by penetrating the long hole, and tightening the clamp bolt to position the steering handle. There is.

[Problems to be Solved by the Invention] However, since the slide mechanism described in the above publication has a structure in which the opposite sides of the slider are slidably contacted with the guide member respectively, the resistance during movement (especially at the start of movement) Is big. Further, the same reason is limited to the case where the moving object is comparatively lightweight, and the moving object becomes difficult when the weight increases. Furthermore, in order to move the slider, it is necessary to provide a certain gap between the opposing side and the guide member, so that the slider is easily rattled.

Further, the conventional positioning mechanism described above is troublesome to operate because the slider is fixed at the fixed position of the guide rail by tightening by rotating the clamp bolt. Moreover, since it is necessary to provide a space required for tightening the clamp bolt by hand, it is difficult to deploy the clamp bolt in a place where the space is limited.

The present invention has been made in view of the above points, and it can be smoothly moved with a small force, the structure is simple and compact, the occupying space is small, there is no rattling, and the operation is simple and constant. It is an object of the present invention to provide a steering device which can be fixed (positioned) in a position and can be easily changed by sliding the position of a steering handle according to a driver's position in a small planing boat in which two people can sit side by side. .

[Means for Solving the Problems] In order to achieve the above-mentioned object, a steering device for a small planing boat according to the present invention comprises: A) a steering wheel, a conversion means for converting a rotational movement of the steering wheel into a reciprocating movement, and The connecting means for connecting the transmitting member for transmitting the reciprocating motion to the steering means is attached to the handle bracket to form one unit, and B) the guide rail disposed in the width direction with respect to the hull is sandwiched, and one side surface thereof is contacted. And a pair of rollers that rotate
A slider having a pair of spring pieces protruding in an arc shape slidably contacting the side surface is formed so as to be movable integrally with each other, and C) the unit is provided via the roller and the slider. It is movably installed.

As described in claim 2, D) a positioning hole is formed in the upper surface or the lower surface of the guide rail, and a positioning pin that can be fitted into the positioning hole and a member for removing the positioning pin are slid in a direction orthogonal to the guide rail. It is preferable that a positioning mechanism that is movable is integrally movable with the roller and the slider.

E) The positioning pin is urged toward the positioning hole via a spring, and a mountain-shaped engaging portion is formed on both side surfaces of the positioning pin, and the positioning pin is disengaged. The member is slidably mounted on the roller and the slider in a direction orthogonal to the guide rail, and F) by pulling the separating member to one side,
It is even more preferable to provide the releasing member with an inclined portion that comes into contact with the chevron-shaped engaging portion and causes the positioning pin to come out of the positioning hole against the spring.

[Operation] According to the steering device of the present invention having the above-described configuration, for example, when two people switch sideways while sitting side by side on a bench seat of a small planing boat, steering is performed at the driver's position. The steering wheel can be easily moved, and when only one person sits in the middle of the bench seat from the balance of a small planing boat to drive, the steering wheel can be easily moved to the middle (driver) position. Can be made. Especially when the steering handle is moved, if the slider is moved by lightly pressing it against the guide rail, the pair of spring pieces of the slider are deformed toward the slider side, and the frictional resistance with the guide rail is reduced. The slider becomes integral with the rolling of the pair of rollers facing each other, and the slider moves smoothly along the guide rail. Also, when moving
Since the slider moves while being supported by the pair of spring pieces and the pair of rollers facing each other, there is no backlash. Further, if the moving operation is stopped when the slider moves to the fixed position, the pair of spring pieces of the slider are restored to the guide rail side and stop.

According to the steering device of the second aspect, the positioning pin is fitted into the positioning hole at a fixed position on the guide rail, and the roller and the slider are fixed. In this state, if the pin detachment member is moved in a specific direction, the pin will come out of the positioning hole and the fixed state will be eliminated, so that the slider can be smoothly moved by pressing it gently against the guide rail. .

According to the steering device of the third aspect, the steering handle is positioned by automatically inserting the positioning pin by the spring force at the position of the positioning hole, and the positioning is easily canceled by pulling the releasing member. , The steering handle can be moved.
