Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a start/stop lever device for a passenger seat of a transport vehicle that runs on a single track laid on steep slopes in mountainous areas.

[Prior Art] Generally, in mountainous areas, monorail-type transport vehicles are used as equipment for transporting agricultural products such as fruits and cargo such as wood.

Conventionally, this type of transportation vehicle consists of a power vehicle and a truck that is a towed vehicle.The vehicle runs unmanned on a single track by the engine of the power vehicle, and when it reaches the loading/unloading point of cargo, the vehicle is turned off by the power vehicle. The vehicle's brakes are automatically applied to stop the vehicle, and it is not equipped to allow people to board the vehicle, but currently workers and others who dislike walking are boarding the vehicle, so It was dangerous and often resulted in personal injury.

In view of this situation, in recent years, passenger seats with seats have been added to the above-mentioned transport vehicles, and levers for manually operating the automatic stop brakes installed on power vehicles, as well as cargo vehicles, etc. A passenger transport vehicle is equipped with a lever for operating the equipped drum-type emergency stop brake on the passenger seat, and is configured so that each brake can be operated from the passenger seat, allowing safe boarding. Proposed
No., Utsukai No. 60-44860, etc.).

By the way, the above-mentioned transport vehicle often travels on steep slopes in mountainous areas, and while traveling on steep slopes, the body of the passenger is significantly tilted toward the direction of travel or the opposite side with respect to the floor surface of the passenger seat. Therefore, if an unexpected situation were to occur while the driver was in such an unnatural position, it would be highly unlikely that he would be able to not only operate the stop brake lever on the power vehicle, but also operate the emergency stop brake lever on the truck, etc. Therefore, the conventional structure of the brake lever for the passenger seat cannot be said to be sufficient as a safety measure for a passenger-type transport vehicle.

Moreover, in the case of the above-mentioned transport vehicle, after reaching the destination by traveling forward, it travels backward to return to its original location, so if the operating direction of the brake lever is different when traveling forward and when traveling backward, an unexpected situation may occur. In sudden situations, such as during an emergency, it is easy to operate the lever in the wrong direction, and there is a risk that the lever cannot be operated quickly.

[Problems to be Solved by the Invention] The present invention has been made to solve the above problems, and is capable of automatically stopping a power vehicle by tilting one start/stop lever in either direction. In addition to operating two brakes: the brake and the drum-type emergency stop brake of the towed vehicle, the braking force of the emergency stop brake can be increased by tilting the start and stop levers in the same direction. It is an object of the present invention to provide a start/stop lever device for a passenger seat that can immediately respond to situations.

[Means for Solving the Problems] That is, the present invention consists of a power vehicle and a towed vehicle equipped with a passenger seat, and the throttle lever of the engine mounted on the power vehicle is operated to a neutral position, so that a single-rail train can be operated. The vehicle is configured to automatically travel forward or backward on the top of the vehicle, and when the throttle lever is operated to a forward or backward tilt position, a stop brake provided on the power vehicle is activated and the vehicle automatically stops. In addition, the towed vehicle is equipped with an emergency stop brake that is operated via an operating wire and whose braking force can be adjusted according to the traction force of the operating wire, and the passenger seat is equipped with an emergency stop brake that is operated via an operating wire and whose braking force can be adjusted according to the traction force of the operating wire. In a single-rail truck equipped with a start/stop lever for operating a stop brake, the start/stop lever is composed of a main lever and an auxiliary lever, and the main lever and the auxiliary lever are provided so as to be swingable in the same direction. By interposing an intermediate member between both levers, when the main lever is tilted in either direction, the sub-lever is also tilted at a predetermined angle in conjunction with the tilting of the main lever, and thereafter only the main lever is tilted in the same direction. The main lever is connected to an operating wire for operating an emergency stop brake, and the auxiliary lever is connected to an operating wire for operating a throttle lever.

[Function] With the above structure, if an unexpected situation occurs while driving on a steep slope, by tilting the main lever in either direction, the secondary lever will also be tilted at a predetermined angle. I will do it.
Therefore, the emergency stop brake is operated via the operating wire connected to the main lever, and the throttle lever is operated via the operating wire connected to the auxiliary lever. Both the stop brakes are in the braking state.
Even if the main lever is then further tilted in the same direction, the intermediate member interposed between the main and sub levers will absorb the remaining movement, and the secondary lever will not be tilted any further. , only the main lever will be tilted. Therefore, only the operating wire connected to the main lever is pulled more strongly, and the braking force of the emergency stop brake increases. Note that when the main lever is tilted in the opposite direction to the above, the secondary lever will also be tilted by a predetermined angle in the opposite direction, and in this case as well, the emergency stop brake and throttle will be activated in the same way as described above. The levers will each be actuated, and both the stop brake of the motor vehicle and the emergency stop brake of the truck will be in the braking state.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. Reference numeral 1 denotes a single rail made of a rectangular tubular body, which is laid at a predetermined height from the ground by supports 2, and a rack 3 is fixed to the bottom surface of the single rail 1 along its length. .

Reference numeral 4 denotes a power vehicle, and the lower portion includes a wheel portion 5 consisting of two upper wheels and two lower wheels that roll along the single rail 1 while sandwiching the single rail 1 from above and below, and a driving wheel that meshes with the rack 3. 6 are provided by being supported by the side surfaces of the side frames 7, respectively. In addition, 8 is the engine mounted on the power vehicle 4, and 9 is the throttle lever of the engine 8, which is in the forward tilted position shown by the one-dot chain line (the position when the stop brake is activated when traveling forward) or in the rear position shown by the two-dot chain line. When the engine is in the tilted position (the position when the stop brake is activated when traveling in reverse), the throttle valve (not shown) is throttled and the engine 8 is rotated at a low speed, and at the same time the stop brake (not shown) is activated. It's starting to come into braking mode. Further, when the vehicle is in the neutral position (position during running) shown by the solid line, the throttle valve is opened and the engine 8 is in a high speed rotation state, and at the same time, the stop brake is released.

This power vehicle 4 automatically moves on the single rail 1 by transmitting the rotational force to the drive wheels 6 via an automatic centrifugal clutch provided in the power transmission section when the engine 8 is rotated at a predetermined speed or higher. When the vehicle starts moving forward or backward, and reaches the loading/unloading point, the stop levers installed on the power vehicle 4 come into contact with the side stoppers of the single track 1 (not shown). As the throttle lever 9 is rotated, the linked throttle lever 9 rotates from the neutral position to the forward or backward tilt position, and as a result, the throttle valve is throttled and the engine 8 is rotated at a low speed. The centrifugal clutch is disengaged, and at the same time the stop brake is automatically applied to bring the vehicle to a stop.

In addition to the above-mentioned stop brake, the power vehicle 4 is equipped with
A constant speed brake to prevent acceleration exceeding a specified value from being applied to the power vehicle 4, and an emergency stop brake to prevent the power vehicle 4 from running out of control in the event that the constant speed brake etc. malfunctions and the power vehicle 4 is about to run out of control. , and is further equipped with a forward/reverse switching lever for switching the running direction of the power vehicle 4.

The configuration of the power vehicle 4 described above is no different from known ones.

Reference numeral 11 denotes a cart which is a towed vehicle, and the front and rear lower portions of the chassis 12 are comprised of two upper wheels and two lower wheels that roll along the single rail 1 while sandwiching the single rail 1 from above and below. Wheel portions 13 and 14 are provided by being supported by side surfaces of side frames 15 and 16, respectively. Reference numeral 17 denotes a drum-shaped emergency stop brake provided on the side frame 15, which is operated via an operating wire 33, which will be described later, and whose braking force can be adjusted in accordance with the pulling force of the operating wire 33.

Reference numeral 21 denotes a passenger seat provided at the rear end extension of the chassis 12 of the truck 11, and above the floor 22 is a straddle-type seat 23 that faces perpendicular to the traveling direction. It is attached by being supported by a rod 24. Further, reference numeral 25 designates a grip handle for the passenger, which is provided upright at one side end of the floor portion 22 so as to be located on the front side of the seat portion 23 .

In the case of the passenger seat 21 having such a configuration, the passenger faces the handlebar 25 and sits astride the seat part 23, and when climbing or descending a slope, the passenger grips the handlebar 25 and leans his or her body against the seat part 23. Use this as a fulcrum and lean to the right or left so that your body is always vertical. By doing this, even when traveling on a slope, the rider can sit in the same stable seating position as when traveling on flat ground. According to the seat portion 23 having such a structure, by simply turning one's face to the right or left while seated, the user can gaze both forward and backward in the direction of travel.

26 is a start/stop lever installed in the passenger seat 21, and is configured as follows. In other words, the main lever 27 is made of a frame 25', which has an intermediate member 28 made of sheet metal fixed to the grip handle 25, which has an intermediate boss part 27' and a V-shaped base end 28' integrated with the boss part at the lower part. By being pivotally attached to the side surface with a pin, the main lever 27 can be pivoted about the pin, and the main lever 27 is branched in two directions in the front and back direction of the passenger seat 21, and the ends of each branch piece 29a, 29b are These parts are referred to as gripping parts 30a and 30b. and a base end 28' that swings in an arc shape with the pin as a pivot point;
That is, the lower end of the intermediate member 28 is located above the secondary lever 31, which can swing in the same direction as the main lever 27 by pivoting the intermediate portion to the frame 25' below the intermediate member. It is fitted into a V-shaped recess 32 formed on the end surface. 33 is a sleeve plate 3 attached to an intermediate member 28 that swings together with the main lever 27.
4' is an operating wire that connects the fixed metal fitting 34 which is pivotally supported and the actuating part of the emergency stop brake 17. It is inserted into a stopper 35 supported by a pin at a position below the pin so that it can be pulled upward via the fixing metal 34 even in the case of an accident. Also 36
is another operating wire that connects the lower end of the sub-lever 31 and one end of the throttle lever 9. A known push-pull cable that can be pushed and pulled is used for this operating wire 36, so that the throttle lever 9 can be operated no matter which direction the sub-lever 31 is tilted.

37 (Fig. 2) is a spare brake pedal installed on the floor 22, which is connected to the power vehicle 4 via an operating wire 38.
The brake pedal 37 is connected to a stop brake, and braking can also be performed by pressing the pedal 37 against the spring 39.

Since the start/stop lever device is configured as described above, if an unexpected situation occurs while driving on a steep slope, one grip part 30a or 30b of the main lever 27 located near the passenger can be moved in either direction. By tilting the main lever 27, the base end of the intermediate member 28, which is interlocked with the main lever 27, slides along one inner surface 32a of the V-shaped recess 32 of the sub lever 31 and rotates the pivot portion of the lever 27. It moves in a circular arc around the center and tilts the sub-lever 31 by a predetermined angle (FIG. 4). Therefore, the emergency stop brake 17 is activated via the operating wire 33 connected to the intermediate member 28 that interlocks with the main lever, and the secondary lever 3
The throttle levers 9 are each actuated via the operating wires 36 connected to the vehicle 1, and the stop brake of the power vehicle 4 and the emergency stop brake 17 of the truck 11 are both brought into a braking state. Thereafter, even if the main lever 27 is further tilted in the same direction, the sub lever 31 will not be tilted any further, and only the main lever 27 will be tilted. Therefore, only the operating wire 33 is pulled more strongly, and the braking force of the emergency stop brake 17 increases. Note that when the main lever 27 is tilted in the opposite direction to that described above, the base end of the intermediate member 28 slides along the other inner surface 32b of the V-shaped recess 32 of the sub lever 31 and tilts the main lever 27. It moves in a circular arc centered on the pivot portion, and tilts the sub lever 31 at a predetermined angle in the opposite direction to the above.
In this case, as described above, the emergency stop brake 17 and the throttle lever 9 are each operated, and the stop brake of the power vehicle 4 and the emergency stop brake 17 of the truck 11 are both in the braking state.

Note that even if the main lever 27 further tilts and the base end of the intermediate member 28 separates from the concave portion 32 of the sub-lever 31 after the sub-lever 31 is tilted by a predetermined angle, the throttle lever 9 is then kept in the neutral position. The sub-lever 31 will not return to its original position from the tilted position unless it is returned to its original position.

6 and 7 show a second embodiment of the start/stop lever device. That is, the portion above the base end 27'' of the main lever 27 having the gripping portion 30 is pivotally attached to the side surface of the gripping handle 25 by a shaft 41, so that the lever 27 is provided so as to be swingable in the front-rear direction of the transport vehicle. , and the base end 3 extending downward of the sub-lever 31.
The lever 31 is provided so as to be swingable by pivotally connecting the portion above 1' to the shaft 41, and the portion from the pivoting portion to the gripping end is pivoted in both directions in the front and rear directions of the carrier. Form a branch into each branch piece 4
2a, 42b are provided with gripping portions 43a, 43b, and an intermediate member 44 made of an elastic body such as a coil spring is provided between the portion above the pivoting portion of the main lever 27 and each of the branch pieces 42a, 42b of the sub lever 31. , 44, and furthermore, a stopper 4 that restricts each branch piece 42a, 42b from tilting beyond a predetermined angle.
5 and 46 are provided on the side surface of the grip handle 25. Then, the operation wire 33 for operating the emergency stop brake is connected to the base end 27'' of the main lever 27 by rising upward from the end fixed position immediately below the base end, and the base end 31 of the sub lever 31 An operating wire 36 for operating the throttle lever, which can be operated by either the push or pull operation described above, is connected to '.

In the case of the above configuration, by tilting the main lever 27 by tilting the grip portion 30 of the main lever 27 in either direction, the sub lever 31 also moves to the stopper 45 or 46 via the intermediate member 44 made of an elastic body.
It will tilt until it hits . Therefore, as described above, the emergency stop brake 17 and the throttle lever 9 are activated, respectively.
Both the stop brake of the power vehicle 4 and the emergency stop brake 17 of the truck 11 enter the braking state. Then, even if the main lever 27 is further tilted in the same direction against the intermediate member 44 made of an elastic body, the sub lever 27
Since the main lever 1 is restricted by the stopper 45 or 46, it will not be tilted any further, and only the main lever 27 will be tilted. Therefore, only the operating wire 33 is pulled more strongly, and the braking force of the emergency stop brake 17 increases as described above. The above also applies when the main lever 27 is tilted in the opposite direction. The emergency stop brake 1 can also be activated by tilting the grips 43a and 43b of the sub-lever 31.
7 and throttle lever 9 can be operated together.

In the above description, the seat portion 23 of the passenger seat 21 is configured as a straddle structure in which the passenger sits facing perpendicular to the traveling direction, but the structure is not limited to this, and the seating direction, the structure of the seat portion, etc. may be carried out as appropriate.

In addition to providing the passenger seat 21 on an extension of the chassis 12 of the truck 11, the passenger seat 21 may also be provided on a passenger truck separate from the truck, so that the truck and the passenger truck constitute a towed vehicle. It's okay.

Further, the emergency stop brake 17 may be provided not only on the cart 11 but also on a passenger cart.

[Effects of the Invention] As is clear from the above, according to the present invention, by tilting one start/stop lever, two automatic stop brakes for the power vehicle and a drum-type emergency stop brake for the towed vehicle are activated. In addition to being able to operate the brake, by further tilting the start/stop lever in the same direction, the braking force of the emergency stop brake can be increased without interfering with the operation of the stop brake of the power vehicle, so it is possible to We will be able to respond immediately.

Moreover, according to the present invention, the start/stop lever is pivotably mounted so that the brake can be operated by tilting it in any direction, so the lever can be operated whether the lever is moving forward or backward. You can't go wrong with this. Therefore, in the event of an unexpected situation, the lever can be operated quickly.
