JPS6047459B2 - Idling operation structure in marine engine control equipment - Google Patents

Description

[Detailed Description of the Invention] The present invention provides a control device (hereinafter simply referred to as a single-lever control device) in which a clutch switching operation and a throttle opening/closing operation of a marine engine can be performed remotely using a single operating lever. The present invention relates to a structure in which idling operation can be performed with only one hand rotating the operating lever.

Single-lever control devices require only one hand (for example, only the left hand)
It is extremely convenient because it allows the clutch and throttle of a marine engine to be operated using the same method.Therefore, several types of inventions and ideas have been made.

However, the idling structure of these control devices were all operated with the other hand (for example, the right hand).
This type of control device is often used in small watercraft such as motorboats, but the smaller the boat, the more it will be shaken by even small waves, and this shaking will require both hands to operate the idling operation. There was a serious drawback in that it was easy to lose balance, which was not only dangerous, but also made it difficult to operate the engine when idling. The main object of the present invention is to provide a structure that allows not only clutch and throttle operation but also idling operation with only one hand rotating the operating lever.

Another object of the present invention is to provide an idling structure in which the thickness of the control device can be made thinner than before by providing the idling operation structure on the control lever side, the control device can be made smaller in size, and the idling structure is more versatile. There is something to do.

Another object of the present invention is to provide a structure that allows accurate idling operations as described above without losing the balance of the body during idling operations.

An embodiment of the present invention will be explained with reference to the drawings.

and the inner circumferential surface 1e of the third protrusion 1e (see FIG. 2).

A spring 27 is fitted between the handle 12 and the finger hook 15 under some compression. The functions and effects of the present invention will be explained below.

Place one hand on the handle 12 of the operating lever 9 and move the lever to C.
When the sliding rod 15 is rotated in the E direction, the sliding rod 15 is pushed in the E direction by the repulsive force of the spring 27, so that the bent portion 16 of the sliding rod touches the inner peripheral surface of the annular convex portion 2b of the clutch shaft 2. 2b'' (
The second protrusion 1h of the casing 1 is fitted into the groove 18 of the slider 17, and the circular protrusion 26 of the operating lever 9 is in a rotatable state (the two protrusions may be separated by some distance). The outer peripheral surface 2b'' of the annular convex portion 2b of the shaft 2 and the first
Since it is fitted into the groove 25 formed between the protrusion 1g and the inner circumferential surface 1g'', only the lever shaft 3 fixed to the rectangular recess 24 of the operating lever 9 by the engagement means 3a can be moved. This rotates the throttle cable actuating member 6 in the G direction to actuate the throttle operating control cable whose one end is connected to the connecting means 6a, and the throttle is rotated at the neutral position of the clutch (not shown). Increase the opening degree to allow idling operation.

In this case, the concave groove 25 and the groove 11C provided in the slider 11 are lined up at the same position, and the circular protrusion 26 of the operating lever 9 smoothly slides within the groove 11C, thereby controlling the rotation of the operating lever. Does not interfere. Return the operating lever 9 to the neutral position (the position shown in FIG. 1) and then move the sliding rod 1 together with the handle 12.
5 is grasped by hooking a finger on the finger hook 15a and pulling it in the F direction, the bent part 16 of the sliding rod comes into contact with the tongue part 11e of the slider 11 and moves the slider in the F direction, Eventually the bending part 1
6 is fitted into the notch 2d of the clutch shaft 2, and the second sliding surface 22 of the slider 17 is the outer peripheral surface 1h of the outer peripheral surface 1h of the second protrusion 1h.
'', and the outer circumferential surface 1h'' has the same circumference as the outer circumferential surface 1e'' of the third protrusion 1e,
The operating lever 9 can be rotated in either direction C or D from the neutral position.

Therefore, as shown in FIG. 2, the throttle cable actuating member 6 is in the G and H directions, and the clutch cable second actuating member 5, which is engaged with the clutch cable first actuating member 4, is in the I and J directions. It can be operated to switch the engine's clutch forward and backward and adjust the throttle opening. Although the illustrated throttle cable operating structure and clutch cable operating structure are only one example of the known structure, the idling structure of the present invention can be used even with other known structures, and the idling structure of the present invention is versatile. It is rich. As mentioned above, with the present invention, the idling of the marine engine and the operation of the clutch and throttle can be done with just one hand, which is more convenient than ever before, and prevents the operator from losing his or her balance even when the waves are high. do not have.

In addition, because the structure does not require idling operation by operating the clutch cable operating member and throttle cable operating member in the control device in the axial direction as in the past, the thickness of the control device can be thin, and the device can be made smaller. This has an excellent effect of not making the cockpit narrow. θ In the embodiment shown in the drawings, the slider 11 is provided with a notch 11b and the second sliding surface 22 of the slider 17 is provided with a substantially mountain-shaped protrusion 22a. The repulsive force of the splash 27 causes the notch 11b
The notch effect is obtained when the operating lever 9 is in the neutral position.

However, it goes without saying that the notch 11b and the protrusion 22a may be omitted.
