Abstract

PURPOSE:To facilitate the operation of an operating handle by combining the operating handles for two systems which operate an actuating device for actuating the car body driving part of a specially equipped truck. CONSTITUTION:The joint part 2 of a three-position operating rod 1 which is connected to a three-position operated body, is rotatably fitted to a shaft 5 which is loosely inserted in the intermittently moving hole 4 of an intermittently moving arm 3. And, the joint part 8 of a two-position operating rod 7 which is connected to a two-position operated body in a vehicle, is rotatably fitted to a shaft 6 which is provided on the lower end of the intermittently moving arm 3. The upper part of the intermittently moving arm 3 is rotatably fitted to a shaft 11 on which an operating handly 9 and a supporting frame 10 are rotatably mounted, and a bolt 12 for adjusting the position of the shaft 5 for the three-position operating rod 1, is provided on one side of the intermittently moving arm 3. When the shaft 5 is in a position where it is not engaged with either the right inside or left inside of the hole 4, the three-position operating rod 1 is not moved either rightward or leftward, maintaining a stopped condition by the amount of the interval of space of the hole 4, even while the operating handle 9 is rotated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is to make the operating handle of two systems for operating the actuating device for actuating the vehicle body drive part of a specially equipped truck compact and easy to operate. This relates to an operating nondle device for the purpose of.

Conventional specially equipped trucks, for example, dump trucks, usually use two operating handles to operate the expanded 3-position operated body and the 2-position operated body, resulting in a small seating space for the driver. It is difficult to operate, and the driver has to use two different operating levers.

According to the present invention, the space for the driver's seat is widened, the operation is easy, and the handle device can be made compact.

As shown in FIGS. 1 and 2, the first invention is to connect the joint part 2 of the 3-position actuating rod 1 connected to the 3-position operated body (not shown) in the vehicle to the intermittent movement hole of the intermittent arm body 3. A joint part 8 of a two-position actuating rod 7, which is connected to a shaft 6 provided at the lower end of the intermittent arm body 3 and a two-position operated body (not shown) in the vehicle, is pivotally attached to a shaft 5 that is loosely fitted in the intermittent arm body 3. The upper part of the intermittent arm body 3 is pivoted to a shaft 11 that is pivoted to the operating handle 9 and the support frame 10,
A 3-position operating rod 1 for a 3-position operated object is provided on one side of the intermittent arm body 3.
The shaft 5 is located within the intermittent motion hole 4 and has an adjustment bolt 12 screwed thereon to adjust its range of motion. The adjustment bolt 12 can be fixed with a tightening nut 13, and the 3rd and 2nd position operating rods 1.7 are engaged with locking portions 14 fixed to the support frame 10. .7
The joint 2.8 provided at the rear end may be omitted and the rear end of the operating rod 1.7 may be connected directly to the shaft 5.6. Also 15.16.
17 is a split pin.

The present invention provides a support frame 10 formed in a U shape as described above.
A letter-shaped operating handle 9 is pivoted on a shaft 11, and by grasping the operating handle 9 and rotating it around the shaft 11, the intermittent arm body 3 provided on the operating handle 9 can be moved. When the shaft 5 of the 3-position operating rod 1, which is loosely fitted into the intermittent movement hole 4 formed in the body 3, is engaged with the inner right side or the inner left side of the intermittent movement hole 4, the 3-position operating rod 1 is moved to the right or to the left. Although it is moved to the left, when the shaft 5 engages with the inner right side or the inner left side of the intermittent movement hole 4 and is in the crawling position, the 3-position operating rod 1 does not move to the right or left and the 3-position operating rod 1 does not move to the right or left. 1 maintains a stopped state by the space interval of the intermittent movement hole 4 even when the operating nondle 9 is being rotated, and moves intermittently to the right or left.

Further, when the intermittent actuating body 3 moves to the right or left, the two-position actuating rod 7 provided below the intermittent actuating body 3 also moves to the right or left according to the movement.

To explain the operating state of the present invention with reference to Fig. 3, the 3-position operating rod 1 connected to the 3-position operating type operated body in Fig. 3 is indicated by the upper 3-position (dump) control line; The 2-position operating rod 7 connected to the 2-position operating type operated body is a 2-position operating lever 7 that controls the engine power take-off device (PTO).
PTo) control lines are shown, and the operating status of the intermittent actuator 3 is shown above each line.
), the neutral operation handle is lowered (OFF) in the middle man position (see Figure 3), the operation handle is lowered (OFF) in intermittent arm disconnection, and the operation handle is neutral (OFF) in the 8th position.
N-m-neutral), intermittent arm is OFF
In the C position, the operating handle is raised (ON), the intermittent arm is in contact (ON), and in the D position, the operating handle is returned to neutral (N), and the intermittent arm is in contact (ON). ), and if you return the operating handle further, it will return to the initial position A.

In the second invention, as shown in FIGS. 4 and 5, a 3-position operating rod 1 connected to a 3-position operated object (not shown) is connected below an operating member 18 provided with an operating handle 9. Then, the actuating member 18 and the intermittent arm body 3 are pivotally attached to the support frame 10 by the shaft 11, and the intermittent arm body 3 is moved intermittently: F1. a Vc operating member 18, the ax shaft 5 is facing upward, and the 2-position operating rod 7 connected to the 2-position operated body (not shown) is connected above the intermittent arm body 3, and the intermittent movement hole is Axis 5 of actuating member 18 in 4
This is an operation/handle device characterized in that an adjustment bolt 12 for adjusting the range of motion of the arm is screwed onto the intermittent arm body 3.

In the figure, 19 is a stopper pin that stops the operation of the shaft 5, 21 is a spring provided on the stopper pin, and 21 is a stop ring that guides the stopper pin.

The operating states of the invention of Fang 2 are AlB, C, and D shown in Fig. 6, where A indicates running down, B indicates neutral, C indicates rising, and D indicates neutral, and the operation thereof is explained in the first invention. This is my understanding.

In the second invention, the shaft 5 and the position where the shaft 5 engages with the intermittent movement hole 4 are in the opposite direction to the position shown in FIG. Since the member 18 is connected to the lower side and the two-position operating rod 7 is connected to the upper side of the intermittent arm body 3, the operating state thereof is the same as that of the first invention.

Further, the first and second inventions can be provided not only on the side of the driver's seat but also in an operable range such as near the flame removal lever of the truck, with the handle shaped, the direction of the handle, etc. appropriately formed.

As described above, each of the inventions allows two systems of operation, a 3-position operated body and a 2-position operated body, to be operated with a single operation handle, so not only is the operation extremely easy and safe driving, but also the structure of the present invention In addition to being compact, it can be installed in the narrow space of the driver's seat, and the complexity of operating two operating handles separately as in the past can be omitted, allowing two systems of operation. It has the advantage of being able to operate smoothly with a single operating handle and preventing operational errors.
