Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steering handle lever device which is attached to a steering handle of a snowmobile or a watercraft running or sailing by an engine and which is suitable for use in controlling the speed of the snowmobile or watercraft.

[0002]

[Prior art]

 Generally, in a snowmobile or a watercraft, the operation of adjusting the output or speed is performed by an operation lever attached to a steering handle. The operating lever is rotatably attached to the end of the steering handle, and is installed in the intake passage of the engine by pushing the steering handle with the thumb of the hand or pulling it forward with the index finger or middle finger. The throttle valve is operated to open against the elasticity of the return spring.

In recent years, the output of the snowmobile and the watercraft tends to be set higher in accordance with the demand for higher performance. Therefore, the operating lever is inadvertently careless during habituation or when a beginner is driving. If operated to the maximum opening, the engine may be damaged or operation may be incorrect. To solve such a problem, it is necessary not to operate the engine to the maximum output of the operating lever until you are sufficiently proficient. However, it is not always the case that the same person operates, and drivers with different skills Since it may be maneuverable, it is preferable to be able to adjust the maximum output.

[0004]

[Problems to be solved by the device]

 As described above, the present invention makes it possible to adjust the maximum operated position of the operating lever so that the maximum output of the engine can be adjusted and the adjustment can be easily performed by the driver. Is an issue.

[0005]

[Means for Solving the Problems] The present invention has the above-mentioned problems, and has a supporting member attached to a steering handle and an operating lever pivotally supported by the supporting member, The problem is solved by providing a control means for restricting the operating end, which includes a protrusion provided on one side of the operating lever and a stopper member provided on the other side. Specifically, it has a support member attached to the steering handle, and an operation lever pivotally supported by the support member. The operation lever is provided between the support member and the operation lever. This is solved by providing a control means for the operating end, which is composed of a protrusion and a stopper member provided on the support member. Further, more specifically, the operation end regulating means is provided by providing an adjusting means for advancing and retracting toward either side of either the stopper member or the protrusion.

[0006]

[Action]

 When the operation lever is rotated from the initial position to the limit of the operation range, that is, to the operation end, the protrusion provided on the operation lever and the stopper member provided on the support member come into contact with each other, and the driver operates the operation lever to move it. Even if the above operating force is applied, the operating force will not be transmitted to the throttle valve. Therefore, if the play of the operating wire is adjusted appropriately, the opening of the throttle valve will be smaller than the full opening even if the operating lever is operated to the fully open position.

Further, if the adjusting member is provided on either the stopper member or the protrusion, the position where the stopper member and the protrusion contact each other is changed, and the gap between the operation lever and the handle grip can be easily operated at hand. Change.

【Example】

 The present invention will be described below with reference to the illustrated embodiments. In the figure, reference numeral 10 is a steering handle for a snow vehicle, which comprises a handle pipe 11 made of steel pipe. Reference numeral 12 denotes a hard rubber handle grip fitted to both ends of the pipe 11. A lever device 20 for controlling the output of the engine is provided inside the handle grip 12. The lever device 20 has an operation lever 21 extending substantially in the same direction as the handle grip 12 for opening and closing a throttle valve (not shown) interposed in the intake passage. In the figure, S is the distance from the handle grip 12 when the operating lever 21 is operated to the maximum extent.

The lever device 20 supporting the operation lever 21 has a support member 22 attached to the steering handle 10. The support member 22 is composed of two upper and lower members 22y 1 and 22z 2 made of synthetic resin, and they are fastened by bolts (not shown) in a form of pressing the handle pipe 11 from above and below. The operation lever 21 is rotatably supported at its root by a pivot 23 with respect to its support member 22. Reference numeral 30 denotes a control means of the operation end for restricting the operation range of the operation lever 21, and in particular, adjusts a rotation angle from the initial position to the operation end, that is, an operation angle. Is performed by the adjusting means 31.

The operating lever 21 is made by injection-molding synthetic resin, has an inverted U-shaped cross section as shown in FIG. 2, has leg portions 21a, 21a on both sides, and a driver's back portion 21b. It is structured so that the finger of "A" is pulled toward the handle grip 12 side. That is, the operation lever 21 has its legs 21a, 21a penetrated by a pivot 23, and is attached to the support member 22 by the pivot 23. Further, the regulating means 30 is provided between the leg portions 21a, 21a for regulating the operating range of the operating lever 21.

Reference numeral 24 is an operation wire made of Bowden wire, and an inner wire 24b thereof is connected to the operation lever 21 through a Tyco metal fitting 24a provided at one end, and the other end is connected to an unillustrated throttle valve of an engine. It is connected. Further, a male screw portion is formed at an end portion of the outer cable 24c supported by the support member 22 as an adjusting means for adjusting the play of the operation wire. It is fixed by 24d. Thus, if the lock nut 24d is loosened and the male screw portion is rotated to advance and retreat, the length of the outer cable 24c is changed, the sliding range of the inner wire 24b is changed, and the so-called play amount is increased. Can be adjusted. Note that this method of adjusting the size of play is not new.

The regulating means 30 includes a stopper member 33 supported by a support portion 22 a extending from one end of the support member 22 to the handle grip 12 side, and a protrusion 32 formed on a part of the operation lever 21. When the operating lever 21 is operated more than expected, the protrusion 32 comes into contact with the stopper member 33 and is prevented from rotating further.

The protrusion 32 is formed integrally with the operation lever 21, and has a substantially semicircular cylindrical surface that protrudes toward the stopper member 33. That is, as shown in FIG. 2, the leg portions 21a of the operating lever 21 are formed so as to project in a pin shape on the inner side of each leg portion 21a, 21a.

The stopper member 33 includes the support portion 22a and several members supported by the support portion 22a. That is, it is fitted in a groove 22f (FIG. 2) formed along the longitudinal direction of the handle pipe 11 formed in the support member 22, is slidably supported, and is screwed into the adjustment bolt 22d. ing. A through hole is formed in the support portion 22a, and a bush 22c with a collar is fitted therein, and further, the bush 22c rotatably supports the adjusting bolt 22d. The adjustment bolt 22d is prevented from coming off by the circlip 22e and is prevented from moving in the axial direction. The tip portion of the adjusting bolt 22d is rotatably fitted in a through hole provided in the support member 22, so that the support is stable and the rotation is smoothly performed. In addition, a coil spring 22j presses it to one side so that it does not generate noise when the vehicle vibrates.

As described above, the adjustment bolt 22d is prevented from moving in the axial direction, and the stopper member 33 is prevented from rotating by the groove 22f. As a result, the stopper member 33 is adjusted. When the adjusting bolt 22d forming the means 31 is pivotally operated, the adjustment bolt 22d is smoothly advanced and retracted in the longitudinal direction of the handle pipe 11, in other words, with respect to the protrusion 32. Therefore, the moving end of the protrusion 32 can be adjusted.

The operation and operation of this embodiment will be described. The solid line in FIG. 1 shows a state in which the operating lever 21 is not operated and is returned to the initial position by being pulled by the return spring of the throttle valve (not shown). From this state, the operating lever 21 is operated to rotate in the operating direction (the direction in which the operating wire 24 is pulled), and when it reaches the operating end, the operating lever 21 projects as shown by the two-dot chain line in the figure. The child 32 contacts the stopper member 33, and further rotation is blocked. Therefore, even if a further operating force is applied to the operating lever 21, the force is not transmitted to the operating wire 24, so that unnecessary strong tension is not applied to the operating wire 24. Further, in this state, if the play of the operation wire 24 is adjusted so that the throttle valve is fully opened, it is possible that the throttle lever is not fully opened even though the operation lever 21 is operated to the maximum position. It will not occur.

Next, the adjustment of the distance S between the operation lever 21 and the handle grip 12 when the operation lever 21 is rotated to the operation end will be described. The size of the interval S is adjusted according to the driver's preference and skill, and is also adjusted to change the opening of the throttle valve when the operation lever 21 is operated to the operation end.

This adjustment is made by an adjusting means 31 which is part of the regulating means 30. That is, the adjustment bolt 22d is rotated by a screwdriver or other tool. When the adjustment bolt 22d is turned with a screwdriver or other tool to advance the stopper member 33 toward the protrusion 32, the protrusion 32 abuts the stopper member 33 at a relatively small rotation angle, and the initial position of the operation lever 21 is changed. The operating angle from the time to contacting the stopper member 33 is reduced. On the contrary, if the stopper member 33 is moved away from the protrusion 32 (to the right in the figure), the operating angle of the operating lever 21 increases.

In the above embodiment, the operating lever 21 is arranged in front of the driver and is operated by the fingers other than the thumb in the direction of pulling it toward the handle pipe 11 side. The concept is not limited to this, and is a concept that can be applied to and includes a type in which the operation lever 21 is arranged on the driver side and is operated in the direction of pressing the handle pipe 11 side with the thumb.

Further, in the above-described embodiment, the protrusion 32 and the stopper member 33, which form the control means of the operation end, are provided on the operation lever 21 and the support member 22, respectively, but the relationship is not limited to this. On the contrary, if the protrusion 32 is provided on the support member 22 and the stopper member 33 is provided on the operation lever 21 side, it goes without saying that it is included in the concept of the present invention.

[0021]

[Effect of device]

 As described above, since the operating end of the operating lever 21 is regulated by the regulating means 30 as described above, even after the operating lever 21 reaches the operating end, even if the operating lever 21 is fully operated, the rotation is controlled by the regulating means 30. The movement is restricted, and the operation force does not reach the operation wire or other transmission means. That is, the throttle valve cannot be opened any further. Therefore, the restricting means 30 can restrict the opening range of the throttle valve and adjust the maximum output of the engine.

Further, if the regulating means 30 is provided with the adjusting means 31, the maximum operating position of the operating lever 21 can be adjusted at the portion of the steering handle 10 close to the hand, so that the adjusting operation is easy. There is.

If the adjusting means 31 forming the restricting means 30 is arranged inside the operating lever 21 having an inverted U-shaped cross section, the adjusting mechanism is not exposed to the outside and the appearance can be improved. Further, if the adjusting bolt 22d forming the adjusting means 31 is oriented substantially in the same direction as the operating lever 21, the adjustment handle 22 is exposed to the side of the steering handle 10, so that adjustment is facilitated.
