Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operating system switching device used when two operating sections are selectively used to operate one driven section.

[Prior Art] When one controlled object is remotely controlled from two locations separated from each other, for example, when controlling the engine from two locations on the bridge and the cabin in a small ship, or when controlling the engine from two locations on the bridge and the cabin in a construction vehicle, When controlling the engine, hydraulic valves, etc. from two locations outside the vehicle, a mechanical remote control device using a push-pull cable is generally used.

In such cases, conventional methods have been used to connect two operating levers in series with the driven part, but in this way, when one operating lever is operated, the other operating lever and the push-pull cable between them are disconnected. Since they are moved at the same time, not only does a large operating force be required, but the durability of push-pull cables and the like is likely to be impaired.

As a solution to the above problem,
A switching device as seen in Publication No. 8 was proposed. In other words, this prior art connects two input cables led to two operating sections to a latch member made in a special shape, and connects a switching lever prepared separately from the operating sections. By switching and setting the movement position of the latch member using the latch member, only the selected one of the input cables is configured to move the driven portion.

[Problem 8 to be Solved by the Invention] However, the above-mentioned prior art has a problem in operability because the switching lever must be operated each time the operating system is switched. Furthermore, since a switching lever and a switching cable connected to the lever are separately required, installation on a ship or the like is time-consuming, requires a large number of parts, and is expensive.

Therefore, an object of the present invention is to provide an operating system switching system that can eliminate the switching lever that requires switching each time when changing the operating system, facilitates operation, and eliminates the need for switching cables, etc. The goal is to provide equipment.

[Means for Solving the Problems] In order to achieve the above object, the present invention employs the following configuration. That is, a guide part provided on the base body, a pair of movable racks provided movably along the guide part and parallel to each other with gear parts facing each other;
An intermediate gear that meshes with the gear portions of both racks and can roll in the longitudinal direction of each rack, a first operating force transmission member connected to one rack, and a second operating force transmission member connected to the other rack. An operating force transmitting member, an interlocking member that transmits the relative movement of the intermediate gear in the longitudinal direction of the rack to the driven part, and a stopper for stopping the movement of the other rack when the one rack moves. It is equipped with

As the locking means, a locking mechanism having the following configuration may be used. In other words, this locking mechanism includes a guide groove that is provided in a substantially U-shape across both racks and has openings at both ends facing the rack, and a guide groove that is provided in a substantially U-shape across both of the racks, and when the rack is stopped at a predetermined reference position with respect to the base body. An engagement recess provided at a position corresponding to the opening of the guide groove, and an engagement of each rack when the rack is accommodated in the guide groove so as to be movable along the groove and is at the reference position. When one rack is biased in the direction of engagement with the recess and moves, this rack is disengaged from the engagement recess and is pushed into the guide groove, causing the other rack to engage. and a locking member that is pressed toward the recess to prevent movement of the other rack.

Moreover, as another aspect of the movement stopping means, a stopper may be provided at a position facing the longitudinal end surface of the rack, so that the rack can be moved only in one direction.

[Function] In the device of the present invention having the above configuration, when one rack (first rack) is moved by the first operating force transmission member, the intermediate gear rotates as the rack moves and rotates in the same manner as this rack. move in the direction. At this time, the other rack (
The second rack) is subjected to a force in the opposite direction, but is kept stationary by the detent means. That is, when the above locking mechanism is adopted, when the first rack moves, one end of the locking member in the guide groove is pushed into the guide groove, and the other end of the locking member is pushed into the second end. Since it is pressed toward the engagement recess of the rack, movement of the second rack is prevented. When the intermediate gear rolls in the longitudinal direction of the rack as the first rack moves, the movement of the intermediate gear is transmitted to the driven part via the interlocking member.

When the second rack is moved by the second operating force transmission member, the movement of the first rack is blocked, and the intermediate gear rotates as the second rack moves. Move in the same direction as the rack. Therefore, similarly to the above, the movement of the intermediate gear is transmitted to the driven part via the interlocking member.

The guide portion 94 is provided with a pair of movable racks 96 and 97. These movable racks 96 and 97 are held movably along guide walls 91 and 92, with gear portions 98 and 99 facing each other and parallel to each other. The distal end portion of the core 102 of a χ tushable cable 101 serving as a first operating force transmission member is connected to one rack 96. The end of the outer tube 103 of the push-pull cable 101 is fixed to the base body 90 by a stopper 104. This stopper 104 is fixed at an appropriate position in one of the plurality of mounting holes 105 provided on the base body 90 for position adjustment. The other end of this push-pull cable 101 is connected to the first operating section 4
It is connected to the throttle output terminal of No.2.

The other rack 97 is connected to a distal end portion of a core 109 of a push-pull cable 10B serving as a second operating force transmission member. The end of the outer tube 110 of the push-pull cable 108 is connected to the base body 9 by a stopper tti.
Fixed to 0. This stopper lll is also fixed at any suitable position in the hole 112 for a plurality of attachments for position adjustment. The other end of this push-pull cable 10g is connected to the throttle output end of the second operating section 52.

An intermediate gear 115 is engaged with the gear portion 98.99 of the movable rack 96.97 so as to be rotatable in the longitudinal direction of the rack 96.97. The support shaft 11B of this intermediate gear 115 is inserted into a long hole 117 provided in the base body 90, and the intermediate gear 115 is guided along this long hole 117 together with the support shaft 11B! ! 91.92 so that it can be moved in the longitudinal direction.

is provided.

If the push-pull cables tot,...tea connected to the operating section 42.52 are of the pull-to-open type, the switch 21 shown in FIG. Stopper 184 at the other end,
115 may be provided.

Next, the operation of the engine control system 10 including the two types of switching devices 20 and 21 configured as described above will be explained.

Lever 41 of operating part 42.52 as shown in FIG.
．． 51 to the neutral position, shift lever 1 of engine 13
4 is in the neutral position, and the throttle lever 15 is in the idling position.

As shown in FIG. 8, the lever 4 of the first operating section 42
1 to F, the first cable 3 for shift control
As the core 36 of No. 5 moves in the bushing direction, one of the racks 30 slides to the right in the drawing. When one rack 30 begins to move in this manner, one roller 78 in the locking mechanism 71 is disengaged from the engagement recess 85, and the roller 78 is moved into the guide groove 85 as shown in FIG.
Pushed into 0. For this reason, the other roller 79 remains fitted in the engagement recess 86 and cannot be moved, so the rack 3
1 is stopped.

As described above, only one rack 30 is attached to the guide wall 23.
When moving forward along the rack 30, the intermediate gear 54 meshing with the rack 30 moves in the same direction as the rack 3o. Therefore, when the second link 62 rotates clockwise in the drawing via the first link 61, the core 67 of the shift control cable 66 is pushed, and the shift lever 14 enters the forward position. In addition, if the lever 41 is returned to the N position,
The roller 78 can be fitted into the engagement recess 85 again.

As shown in FIG. 9, when the lever 41 is rotated to the F2 direction, the core 102 of the throttle control cable 101 moves in the bushing direction, causing one rack 96 of the throttle switching device 21 to move forward. do. At this time, an opposite force acts on the other rack 97, but this rack 97 is prevented from retreating by the stopper 135, so it is held at the initial position.

When one rack 96 moves forward along the guide wall 91 by the above operation, the intermediate gear 115 meshing with this rack 96 moves in the same direction as the rack 96. Therefore, when the second link 123 rotates via the first link 122, the throttle control cable 127
core 128 moves, and the throttle lever 15 is rotated.

As shown in FIG. 10, when the lever 41 of the first operating section 42 is pushed down to B1, the core 36 of the first cable 35 for shift control is pulled, causing one rack 3
0 slides to the left in the drawing. At this time, the lock mechanism 7
1, one of the rollers 78 is disengaged from the engagement recess 85, and the roller 78 is pushed into the guide groove 80, thereby stopping the other rack 31 from moving.

When one rack 30 retreats along the guide wall 23 in this way, the intermediate gear 54 also retreats, and the second link 62 rotates counterclockwise in the figure, thereby pulling the core 67 of the shift control cable 66. , the shift lever 14 enters the reverse position.

When the lever 41 is rotated in the 82 direction as shown in FIG. 11, the core 1 of the throttle control cable 101
02 moves in the bushing direction, one rack 96 of the throttle switching device 21 moves forward, and the intermediate gear 115 moves in the same direction as the rack 96.

Therefore, the second link 1 via the first link 122
23 moves, the core 128 of the throttle control cable 127 moves, and the throttle lever 15 moves.

The above operations are all performed using the first operating section 42, but exactly the same operations are performed using the second operating section 5.
You can also do it in 2.

That is, as shown in FIG. 12, the second operating section 52
When the lever 51 is pushed down in the F2 direction via the forward position F1, the second rack 31 is moved in each switching device 20.21.
．． 97 moves along the guide wall 24° 92, and the first rack 3 is moved by the roller 78 and the stopper 134.
By stopping the movement by 0.96, the shift control cable 66 and the throttle control cable 127 are driven. Other basic operations are performed by the first operating section 42.
The same is true for

Furthermore, as shown in FIG. 13, when the lever 51 of the second operating section 52 is pushed down to B2 via the reverse position B, the second rack 31.97 moves and the first rack By stopping the movement of 30.96,
The shift control cable 66 and the throttle control cable 127 are driven.

As described above, according to the control system 10 of this embodiment, even if either the first operating section 42 or the second operating section 52 is operated, the shift lever 14 and the throttle lever 1
Can operate 5. In other words, when one of the operating parts 42, 52 is operated, the other does not become interlocked, so the lever operation does not become heavy and the durability of the push-pull cable etc. is not impaired. Moreover, since there is no need for a switching lever for selecting either one of the operating sections 42, 52, the effort of operating the switching lever can be saved, and a cable for the switching lever is also unnecessary.

Note that instead of the single-lever remote control type operating section 42, 52 in the above embodiment, a two-lever remote control type operating section may be adopted in which shifting and throttle are performed using separate levers.

[Effects of the Invention] As described above, according to the present invention, when the lever of any one of the two operating sections is operated, the operating system is automatically switched. No switching operation is required. Therefore, the operation is extremely simple, and the switching operation from one operating system to the other operating system can be performed extremely smoothly. Moreover, since switching levers, switching cables, etc. can be eliminated, the number of parts can be significantly reduced compared to conventional products, and costs can be reduced, and it is also easy to make rattan into the hull of a ship.
