Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a passenger seat in a single-gauge passenger vehicle, in which a forward/reverse switching lever provided on a power vehicle is provided at a position remote from the power vehicle. This invention relates to a device that can be operated more remotely.

[Prior art]

Traditionally, monorail-type transport vehicles have been used as equipment to quickly and efficiently transport agricultural products such as fruits, wood, and other cargo in mountainous areas where walking is difficult, including hilly areas. A transport vehicle usually consists of a power vehicle and a cart connected to it, and by driving an engine mounted on the power vehicle, it travels on a single track laid at a predetermined height above the ground. It was configured to run unmanned, and was not designed to accommodate a human passenger to prevent accidents.

By the way, when transporting cargo such as fruit using such a transport vehicle, it is necessary to have at least one worker at each loading point and unloading point. Workers who are forced to load and unload cargo at both of the above points are inefficient and tiring to walk between the two points, so other workers who dislike walking are required to do so. They had no choice but to travel in carts without passenger facilities, which was extremely dangerous and often resulted in accidents resulting in personal injury.

Therefore, in view of this situation, in recent years, a new truck with a passenger seat has been connected between the power vehicle and the cart (Japanese Patent Application Laid-Open No. 52-22213, Japanese Patent Application Laid-Open No. 60-60058, etc.). This led to the development of passenger-type transport vehicles that allowed workers to board the vehicle by installing a passenger seat on the connecting rod that connected the vehicle and the cart (such as Utility Model Publication No. 1983-44860). However, the above format is
Since the passenger seat is placed close to the rear of the power vehicle, not only is the ride uncomfortable, but the distance between the front and rear wheels of the power vehicle and truck becomes longer due to the passenger seat, which causes various problems. Therefore, the inventors of the present invention previously proposed in Utility Model Application No. 100684/1983 that a passenger seat is provided at the rear of a cart, away from the motor vehicle.

However, these single-rail transport vehicles, including the ones mentioned above, are equipped with a stop/start lever (throttle lever) on the side of the machine frame of the motor vehicle that can be moved forward and backward, and the lever can be moved up and down perpendicular to the rail. When the stop brake is released and the engine rotates at high speed, the centrifugal clutch is engaged and the engine moves forward (reverse).When the lever is rotated forward or backward by a predetermined angle, the engine rotates at low speed. As a result, the centrifugal clutch is disengaged, and the stop brake is in the braking state.This lever can be operated manually, or it can be operated by the locomotive at a suitable location between the rails (usually near the end/start point). When it hits a stopper, it can automatically rotate forward or backward. In addition, to change the direction of movement of the transport vehicle, manually swing the forward/reverse switching lever provided on a part of the machine frame of the motor vehicle to the right or left (back and forth) along the guide groove of the guide frame. He has made it possible for you to do it.

That is, as shown in FIG. 4, the forward/reverse switching lever includes a rod-shaped lever a with one end as a grip portion, and
It consists of a guide frame c in which a guide groove b is formed to restrict the swinging of the lever, and the lever a is selectively engaged with either recess b ₁ or b ₂ provided in the guide groove b by swinging from side to side (back and forth). At the same time, the lever is biased by a bullet (not shown) in the direction of the arrow to fall into the recess, and when the switching lever a is engaged with one of the recesses, the power vehicle It is well known that the object moves forward, and when it enters another recess, it moves backward.

[Problem that the invention seeks to solve]

By the way, when operating the forward/reverse switching lever, with the type described above, you can reach out your hand from the passenger seat and perform the required switching operation at any time. Even if you can perform other driving operations from the passenger seat, you must get out of the vehicle each time you operate the forward/reverse switching lever, which is extremely troublesome and inefficient.

In view of these circumstances, the present invention not only directly controls the forward/reverse switching lever provided in the above-mentioned power vehicle, but also
The purpose of this system is to enable remote control from a passenger seat located away from the power vehicle, thereby further improving its benefits.

[Means for solving problems]

In order to achieve the above object, the present invention provides a forward/reverse switching lever which is provided on the side of the motor vehicle and is biased downward in the recess of the guide frame, so that the formation direction of the guide groove provided in the guide frame is The above-mentioned switching lever is made by having an inclined surface in contact with the side part, and pressing the contacting part between the switching lever and the inclined surface with an auxiliary lever for forward/reverse switching provided on the passenger seat via a push/pull transmission shaft. It is characterized by moving it to another recess.

The above-mentioned sloping surface is either on both sides of the protrusion facing the concave part of the guide frame, or on the front part of the guide frame and facing the notch of the movable plate that is moved in the direction of forming the guide groove. It is formed on either side.

[Effect]

With the above configuration, when changing the traveling direction of the transport vehicle, the forward/reverse switching lever provided on the power vehicle is operated by an auxiliary lever from a passenger seat located remotely from the power vehicle. This makes it possible to eliminate the need to get off the train each time the direction of travel is changed.

When the engine is in the position shown by the dotted chain line (the position when the automatic stop device is activated while traveling in reverse), the engine rotates at low speed and the centrifugal clutch (not shown) is disengaged, and at the same time the stop brake (not shown) is activated. state. When the position is in the solid line, the engine rotates at high speed, the centrifugal clutch is engaged, and the stop brake is released. Although not shown in addition to the above, this power vehicle 4 has a constant speed brake for preventing acceleration beyond a specified value from being applied to the power vehicle, and a failure of this constant speed brake, etc., which causes the power vehicle to almost run out of control. It is equipped with an emergency stop brake to prevent the vehicle from running out of control.

Reference numeral 12 denotes a truck connected to the rear of the power vehicle 4 via a connecting rod 13, and a single rail 1 is sandwiched between the top and bottom of the chassis 14 at the front and rear lower portions of the platform 14, and a truck rolls along the single rail 1. Moving upper wheels 15,1
5 and lower wheels 16, 16 are provided by being supported by side frames 17, respectively, and the motor vehicle 4 runs on the single rail 1. Reference numerals 18 and 18 indicate luggage racks erected at the front and rear ends of the vehicle chassis 14, and 19 indicates brakes provided at the shaft ends of some of the lower wheels 17.

Although only one cart 12 is shown in the figure, two or more carts can be connected sequentially via a connecting rod. The feature of the present invention is that the forward/reverse switching lever 20 provided in the power vehicle 4 described above can be operated from a passenger seat 21 provided remote from the power vehicle 4. . Furthermore, although the above-mentioned passenger seat 21 is shown as being provided at the extended rear portion of the chassis 14 of the cart 12,
This passenger seat may be provided on a separate trolley or on a following cargo truck.

The passenger seat 21 consists of a seat part 23 disposed laterally on a floor part 22, a grip rod 24 for the passenger erected on the side of the floor part, and a frame 2 provided on the grip rod.
4', an auxiliary lever 25 for stop/start in a Y-shape pivoted so as to be able to swing forward and backward, an auxiliary lever 26 for switching forward and backward, and a brake 19 provided on the lower wheel 17 of the cart 12 (not shown). There are several operating levers and the like.

The forward/reverse switching lever 20 described above has a switching shaft 28 whose base protrudes from a part of the machine frame 27 of the motor vehicle.
The lever 20 is pivoted to the guide frame 29, and the lever 20 is pivoted to the left and right (back and forth) along a guide groove 30 formed in the guide frame 29, and the lever 20 is pivoted to the guide frame 29, and the lever 20 is pivoted to the guide frame 29.
The direction of movement of the motor vehicle 4 can be switched forward or backward by setting the regulation state in which the levers 20 and 30 are depressed. It is being energized.

However, in the present invention, the switching lever 20, which is biased downward in the recess, is moved from side to side by applying a pushing/pulling force from one side of the lever via a transmission shaft, which will be described later. 30a and 30b, and in the embodiment shown in FIG.
is mountain-shaped and both sides 31' are inclined surfaces, and when the switching lever 20 is pushed toward the other recess 30a in the direction of the arrow (A), it tilts against the urging force. While sliding upward, it passes over the mountain-shaped protrusion 31 and moves from the other recess 30b, and when the lever 20 is pulled in the opposite direction of the arrow (A), the lever is moved from the recess 30a to 30b. It is.

In order to avoid the switching lever 20 from moving in a direction other than the horizontal movement by pushing and pulling as described above (diagonal vertical direction) when switching, the second
In the figure, the guide frame 29 is configured to move up and down in a parallel state, and the guide frame 29 is temporarily lowered by the resistance that the protrusion 31 receives when moving in the left and right linear directions by pushing and pulling the switching lever 20. It's good.

While the above is an example in which the switching lever 20 is directly operated by a transmission shaft described later, FIG. 4 shows another embodiment in which the force of the transmission shaft is indirectly applied to the switching lever 20. That is, the protrusion 31 between the recesses 30a and 30b formed in the guide frame 29 of the switching lever 20 fixed on the machine frame 27 has a U-shape as in the general example shown in FIG. 32
is a movable plate that is slidably supported in a groove 33 formed in the machine frame 27 so as to be able to move left and right in a parallel state at the front part of the guide plate 29, and the movable plate has an open upper part and has left and right side edges. A notch 34 is formed with 34' as an upwardly expanding slope, and when the switching lever 20 is dropped into the notch 34 and one recess 30b of the guide plate 29, the movable plate 3
2 in the direction of the arrow (B), the lever moves upward by one side edge 34' in the direction of the arrow (B), and the notch 34 of the switching plate moves in front of the other recess 30a. When the switching lever 20 is pushed downward, the switching lever 20 falls into the recess 30a and the direction of movement is changed.

Since the transmission shaft 35 is well known, detailed illustrations and explanations will be omitted, but the inner wire in a flexible outer tube with both ends fixed is connected from one side by a rod exposed from both ends of the outer tube. The force is transmitted to the other side by the applied push/pull, and the transmission shaft 35 is connected to the switching auxiliary lever 26 provided beside the passenger seat 21 in the embodiment of the present invention.
In the example shown in FIG. 2, the other end is directly connected to a tongue piece 36 protruding from one side of the switching lever 20, and in the example shown in FIG. Due to the need to change the direction of the bell crank 3
The operation of the auxiliary lever 26 is transmitted to the movable plate 32 via the front and rear attached metal fittings 38.

In the embodiment of the present invention, the other transmission shaft 35' is connected between the stop/start lever 11 on the side of the power vehicle 4 and the operating end 25' of the auxiliary lever 25 provided on the passenger seat 21. Therefore, when the auxiliary lever 25 is rotated to an angle where it comes into contact with either of the front and rear protrusions 39a and 39b provided on the gripping rod 24, the stop/start is activated via the transmission shaft 35'. As described above, the lever 11 rotates toward the position indicated by the one-dot or two-dot chain line.

According to the above configuration, the stop/start lever 11 is moved to the first position.
When placed at the solid line position in the figure, the motor vehicle 4 travels in one direction, and when the motor vehicle 4 reaches a predetermined point, the lever 11 comes into contact with a stopper (not shown), or
When the stop/start auxiliary lever 25 provided on the passenger seat 21 is rotated by a predetermined angle, the stop/start lever 11 is returned to the chain line position and the motor vehicle is stopped. Next, when the auxiliary lever 26 for forward/reverse switching provided in the passenger seat 21 is moved to the other side, the force is directly transmitted to the switching lever 20 via the transmission shaft 35 in the example shown in FIG. 20 moves over the slope 31' of the protrusion 31 in the guide frame 29 to the other recess 30a, and in the example of FIG.
The lever 20 is pushed up by the inclined surface 34' and moves laterally to the other recess 30.
If the stop/start auxiliary lever 25 is operated as described above, the motor vehicle 4 will move in the opposite direction.
