Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a single-lever engine control device used to control the throttle or shift of an engine of, for example, a small boat.

[Prior Art] An engine control device for a small boat is, for example, a top-mounted single-lever control device a shown in FIG.
The housing C is installed in a dash hood b of a cabin or the like with the head of the housing C protruding. Therefore, in this case, there are problems with the appearance, and the position of the operating lever d tends to be high, making it difficult to operate. For this reason, there is a tendency to prefer a control device e of the flanche mount type shown in FIG. 11 in which only the operating lever d projects toward the upper surface of the dash board b.

[Problem to be solved by the invention] However, the flush mount type control device e requires the operation lever \-d to be inserted into the hole f provided in the dash hood b, and also requires the rotation of the operation lever 1-d. center g
is located quite below the dash board b, so the hole f
The operating lever d cannot be moved over the desired rotation axis unless the length in the front and rear direction is considerably large.

In addition, if it is necessary to provide an operation section for warm-up operation, in the case of a top-mounted control device a, is it possible to provide the operation section for warm-up operation on the rotating shaft of the operation lever d? In the flush-mount type control device e, the parts other than the operating lever d are hidden inside the dashboard 1'b, so it is difficult to provide an operating section for warm-up operation.

Therefore, it is an object of the present invention to provide a flannel mount type that allows the center of rotation of the operating lever to be mounted on a dash hood, etc. (=1).
The goal is to make it possible to get close to the surface. Still another object of the present invention is to enable an operating section for warm-up operation to be disposed on the mounting surface even in the case of a flush mount type.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a housing fixed to the inside of the mounting surface, a drive shaft rotatably provided in the housing, and a drive shaft provided in the housing. A drive unit that moves the engine control cable in a pull or push direction in conjunction with the drive shaft, an operating lever that is rotatable around a support shaft located near the mounting surface, and this operating lever. A force transmitting means for transmitting the rotational force of the drive shaft to the drive shaft is provided.

In addition, the warm-up slide part side is inserted into the axial hole provided in the drive shaft so as to be movable in the axial direction, and there is also a hole on one end (= one side) near the operation lever. A pusher portion side is provided that protrudes and engages with the end of the slide member so that the other end can press the slide member.

[Operation] When the operating lever is rotated, the drive shaft is rotated via the force transmission means, and the engine control cable is operated by the drive mechanism in the housing. The support shaft, which is the center of rotation of the operation lever, is located at a different position from the drive shaft provided on the housing, and can be placed sufficiently close to the mounting surface. The warm-up slide member inside the drive shaft can be operated from the mounting surface of the dash board or the like.

[Embodiment] An embodiment of the present invention applied to shift and throttle control of a small marine engine will be described below with reference to FIGS. 1 to 9.

As shown in FIG. 1, the housing consists of a housing main body 2 that is open on the negative side, and a cover plate 3 that closes the opening of the housing main body 2. The housing is fixed via a base 5 to a dash hood 6 of the driver's seat, that is, a control device mounting surface. More specifically, the base 5 is fixed to the top plate 8 by screws 7, and the base 5 is fixed to the top plate 8 by screws 7.

It is rotatably mounted on a support shaft 28 provided on the base 5 via two sliding bearings.

The first gear 2] and the second gear 27 constitute a force transmission means for transmitting the rotational force of the operating lever 25 to the drive shaft 20. The diameter of the second gear 27 is greater than the diameter of the first gear 21. Therefore, even if the operating lever 25 and the second gear 27 are rotated by a relatively small angle, the rotation angle of the first gear 21 and the drive shaft 20 can be made large. The operating lever 25 passes through a longitudinally elongated hole 31 formed in the top plate 8 and the decorative cover 9, and protrudes to the upper surface side of the dash hoard 6. A grip 25a is provided at the upper end of the operating lever 25.

An axial through hole 32 provided in the center of the drive shaft 20
A warm-up slide member 33 is inserted through the warm-up slide member 33 so as to be movable in the axial direction. The end portion 34 of the slide member 33 protrudes outward from the end surface of the drive shaft 20. This slide member 33 can be pushed in the axial direction by a warm-up operation mechanism 36. The operating mechanism 36 includes a kite 38 fixed to the base 5 by screws 37, a push member 39 provided to be movable in the vertical direction in the drawing along the kite 38, and a compression spring that biases the push member 39. It is composed of 40 parts. The end portion 34 of the slide member 33 is inserted into a recess 41 provided in a portion of the push member 39. The slide member 33 is inserted into this recess 41 only when the push member 39 is pushed down.
A cam 42 is provided that presses the shaft in the axial direction.

Further, a long hole 43 is provided in the intermediate portion in the length direction of the push member 39.
A member 44 is inserted into the elongated hole 43 to provide a steady rest for the three push members. A rubber cover 4 which also serves as an operation part is attached to the upper end of the three push parts 43.
5 or watertightly coated.

A clutch pin 46 that projects in the radial direction is provided at the other end of the slide member 33. This clutch pin 46 is inserted through a long hole 47 formed in the drive shaft 20. The clutch pin 46 can move in the axial direction of the drive shaft 20 along the elongated hole 47. This clutch pin 46 is removably engaged with a recess 52 of a drive-side gear member 51, which will be described later. Slide member 33
is constantly urged toward the recess 4 by a compression spring 48.

On the other hand, a drive-side gear member 51 is disposed on the outer circumference of the drive shaft 20. This drive-side gear member 51 is formed with a recess 52 into which the tip of the clutch pin 46 can fit. This drive side gear member 51 is connected to the drive shaft 20
However, when the clutch pin 46 is fitted into the four parts 52, the drive side gear member 51
rotates together with the drive shaft 20.

A drive side tooth portion 54 is provided in a part of the drive side gear member 5 in the circumferential direction. Further, the drive gear member 51 is provided with recesses 55, 56, and 57 at three locations in the circumferential direction, located on the opposite side of the drive tooth portion 54. These four parts 55, 56, and 57 engage with a click member 60 supported on the housing body 2 side. This click member 6o
is biased toward the gear member 5 by the spring 6, and any one of the recesses 55, 56, and 57
By engaging elastically in a certain position, a feeling of movement can be obtained.

Further, as shown in FIGS. 1 and 4, ring-shaped lock plays 1 and 6B are provided between the opposing surfaces of the drive-side gear member 51 and the gear case]5.

A drive shaft 20 is inserted through a hole in the center of the long plate 1/63. At the edge of the lock play 1.63, there is a locking portion 65 (a first locking portion) bent toward the gear case 15 side.
) and a second locking portion 66 (see FIG. 4) bent toward the gear member 51 side. The first locking portion 65 is positioned in such a manner that it can enter the window 68 formed in the gear case 15 only in neutral (N In position), which will be described later.

Further, the second locking portion 66 has a length such that it always engages with the hole 70 of the gear member 51 regardless of the position of the lock plays 1 and 63. Lock plate 63 and gear case 1
A compression spring 71 is housed between the gear members 5 and 5, and forces the lock plate 63 toward the gear member 5.

A driven gear member 73 that meshes with the driving tooth portion 54 is provided. The driven gear member 73 is rotatably supported in a bearing hole 74 formed on the inner surface of the housing body 2. This driven side gear member 73 has a driven side toothed portion 76 that meshes with the driven side toothed portion 54, and curved surfaces 77 and 78 formed on both sides of this toothed portion 76. The curved surfaces 77° and 78 are formed to have approximately the same curvature as the outer circumferential surface of the drive side gear member 51. As will be described later, the driven gear member 73 rotates in conjunction with the driving gear member 51 only when the driven tooth 76 is in mesh with the driving tooth 54.

Further, a first drive member 81 is fixed to the driven gear member 73 by a port 80. The first drive member 81 is connected to the tip side of a push-pull cable 82 for shifting.

As shown in FIG. 4, a drive arm 85 and a shaft 86 are attached to the end 20a of the drive shaft protruding from the gear case 15.
Fixed by A roller 87 is attached to the tip of the drive arm 85. and roller 87
The cam member 88 is also driven via. The cam member 88 has a cam groove 90 with which the roller 87 rolls. The shape of the cam groove 90 corresponds to the trajectory drawn by the roller 87 when the drive arm 85 rotates.

A pin 92 is cut out on the lower end side of the cam member 88 in the figure.
An intermediate portion of the second drive section 4493 is pivotally connected via this pin 92. One end side of the second drive part shaft 93 is connected to the housing main body 2 through a shaft 95 provided on the support member 94.
It is rotatably supported.

The free end side of the second drive unit 93 is connected to the tip side of a push-pull cable 97 for the throttle. Therefore, when the cam member 88 moves in the direction shown in the drawing, the second drive member 93 reciprocates as the cam member 88 moves.

Next, the operation of the apparatus of the above embodiment will be explained.

The operating lever 25 is in the neutral position (N position) shown in FIG.
, the click member 60 or the drive side gear member 51
It fits into the four parts 56 of. In this state, the drive-side tooth portion 54 is meshing with the driven-side tooth portion 76, and the roller 87 of the drive arm 85 is positioned exactly at the center of the cam groove 90 of the cam member 88. In this N position, the shift cable 82 connected to the first drive unit 81 is
Maintain the shift of the institution in a neutral position.

The throttle cable 97 connected to the second drive member 9B sets the throttle opening of the engine to the minimum (idling position).

Move the operating lever 25 to the forward position (F position) shown in FIG.
When tilted down, the drive shaft 20 rotates in the opposite direction to the rotation direction of the operating lever 25 via the second gear 27 and the second gear 2, so the drive side gear member 51 rotates via the clutch pin 46
or rotate. Therefore, the driven side teeth 76 meshing with the driving side teeth 54 rotate in conjunction with each other, and the first drive member 81 rotates clockwise in FIG. 6. This pushes the cable 82 and shifts the engine to forward position. At the same time, the click portion +[' 60 enters the recess 55, and the resulting sense of movement allows the operator to know that the driver has entered the forward position (N position). Also, from the N position to the F position, the drive arm 85
Since the roller 87 moves along the cam groove 90, the cam member 88 does not substantially move up and down.
The drive part control 93 does not rotate. Therefore, the throttle cable 97 is not driven and no throttle control is performed.

When the operating lever 25 is tilted from the F position toward the A position shown in FIG. The rotation of the side gear member 73 stops. Therefore, the rotation of the first drive unit 81 is stopped, and the shift cable 8
2 maintains the engine shift in the forward position. On the other hand, since the roller 87 of the drive arm 85 pushes the cam member 88 downward by 1", the cam member 88 moves in the vertical direction in the figure according to the position of the roller 87, and the second drive member 93 rotates. do.

From the Zunawaji F position to the A position, press the operating lever 2.
The amount of rotation of the second drive part 93 changes depending on the rotation position of the second drive part 93, and the amount of push of the throttle cable 97 changes accordingly, making it possible to adjust the throttle opening degree.

Contrary to the above, when the operating lever 25 is returned in the order of A→F-+N positions, each member moves in the opposite direction to the above, returning to the original neutral state.

On the other hand, when the operating lever 25 is pushed down to the R position in Fig. 2,
The drive shaft 20 rotates via the gears 2 and 27, and the first drive unit 81 rotates via the drive side gear member 5, which rotates in the opposite direction to the above, and the shift cable 82 rotates.
is moved in the pull direction and shifted to the engine or reverse position. At the same time, the click member 60 engages with the four portions 57 to produce a sense of motion, allowing the operator to know that the R position has been entered. At this time as well, the roller 87 is connected to the cam groove 90.
, the cam portion +A88 does not substantially move, and therefore the throttle cable 97 is not driven.

Furthermore, if the operating lever 25 is not tilted to the reverse B position, the driven side tooth portion 76 will disengage from the driving side first moving portion 54, so the rotation of the first driving portion 81 will stop, and the engine shift will be maintained in reverse. Ru. On the other hand, since the roller 87 or the cam member 88 is pushed in the vertical direction, the throttle cable 97 moves in the pushing direction according to the angle of the drive arm 85. Conversely, when the operating lever 25 is returned to the B-R-N position, each member moves in the opposite direction to the above and returns to the original neutral position.

Further, according to the device of this embodiment, only throttle control can be performed for warm-up operation.

That is, as shown in FIG.
When the rubber cover 45 of the push member 39 is pushed with a finger when the push member 39 is in the position, the slide member 33 is pushed in by the cam surface 42, and the clutch pin 4 is pushed along the elongated hole 47 (FIG. 4).
6 is also moved in the same direction. As a result, the clutch pin 46 separates from the four portions 52 and disengages from the drive gear member 51. At the same time, the first part of Rock Play 1.63
The engaging part 65 enters the window part 68 of the gear case 15. The second locking portion 66 of the lock plate 63 is connected to the drive side gear member 5.
While remaining engaged with the hole 7o of 1, the drive side gear part +
, I5] are in a state where their rotation is prevented by the gear case 15.

When the operating lever 25 is tilted in the direction shown in FIG.
o rotates and the drive arm 85 also rotates. Therefore, the cam member 88 slides in the vertical direction according to the amount of rotation of the drive arm 85 (the position of the roller 87), and only the second drive section 93 is driven, so that only the throttle cable 97 can be controlled. . Therefore, only throttle control can be performed, for example, during warm-up or when taking out the PTO output. Note that when the operating lever 25 is returned to the N position, the clutch pin 46 and spring 48.71
It automatically enters the four parts 52 due to the repulsive force, and the drive side gear member 51 and the drive shaft 20 are integrated again.

As described above, the device of this embodiment has a flannel mount type that is completely hidden behind the housing 1, the support shaft 28, or the dash board 6, so it has a good appearance. Since the operating lever 25 rotates around the support shaft 28 disposed near the inner surface of the dungeons 1 and 6, even if the length of the hole 31 in the front and rear direction for inserting the operating lever 25 is relatively short. The rotation range of the operating lever 25 can be widened. Moreover, since the first gear 21 with a small diameter is rotated via the second gear 27 with a large diameter, the rotation angle of the drive shaft 20 can be made larger than the rotation angle of the operating lever 25. I can do it. However, the ratio of the diameters of the gears 21 and 27 and the size relationship of the gear diameters are not limited to the embodiment, and in short, the control lever 2
5 and the rotation angle ratio of the drive shaft 20 can be set quite freely. In addition, push the sliding member 33 for warming up provided on the drive shaft 20 from inside the dash board.
, 113 can be easily operated.

In addition, by fixing the housing through the base 5 having a plurality of angle adjustment holes,
The angle at which the insert 1 is taken with respect to the dash board 6 can be set arbitrarily. For this reason, the slope of the dash board 61 and the cable 82
．． The entry direction of the 97 can be selected, making it easy to store the 71 Ujinku 1 in a narrow dash board.

In the above embodiment, the force transmission means is gear 2].

27, or a chain and sprocket may be used instead of gears.

[Effects of the Invention] According to the present invention, the housing and the rotating shaft portion of the operation lever can be completely housed on the back side of the mounting surface of the dungeon port 1, etc., and the appearance is improved. Further, the warming-up operation section can be arranged so that it can be operated from the top side of the dash board or the like.
