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, mole rail-type transport vehicles have been used as equipment to quickly and efficiently transport agricultural products such as fruits, timber, 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 can be moved unmanned on a single track laid at a predetermined height above the ground. It was constructed to be able to travel, and was not designed to allow people to ride on it to prevent accidents.

By the way, when transporting cargo such as fruit using such a transport vehicle, there is at least one space between the loading point and the unloading point.
It is necessary to allocate one worker to another, but currently due to a lack of manpower, one worker is forced to load and unload cargo at both points, and in that case, there is no need for a single worker to load and unload cargo at both points. Traveling on foot is inefficient and highly tiring, so other workers who dislike walking have no choice but to travel in carts without riding facilities, which is extremely dangerous and often results in personal accidents. This resulted in the occurrence of

In view of this situation, in recent years, new bogies with passenger seats have been connected between the power vehicle and the cart (Japanese Patent Application Laid-open Nos. 52-22213 and 60-60058, etc.); This led to the development of a passenger transport vehicle 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, in the above type ■■, the passenger seat is placed close to the rear of the motor vehicle, which not only makes the ride uncomfortable, but also
The installation of a passenger seat increases the distance between the front and rear wheels of the power vehicle and the truck, causing various problems. This was previously proposed in Utility Application No. 100684/1983.

However, these single-rail transport vehicles, including the 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 turned forward or backward by a predetermined angle, the engine speeds down to low speed. When the rail is turned, the centrifugal clutch is disengaged, and the stop brake is in the braking state.This lever can be actuated manually, or the locomotive may be located at an appropriate location between the rails (usually near the start and end points). When it comes into contact with a stopper provided at the top, 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 is even able to do it.

That is, as shown in FIG. 4, the forward/reverse switching lever is made up of a rod-shaped lever A with one end as a grip, and a guide frame C formed with a guide groove for regulating the swinging of this lever.
Lever a is pivoted left and right (back and forth) so that it can be selectively engaged with any of the recesses S, B2 provided in the guide groove, and the lever is moved into the recess by an elastic force (not shown). It is well known that when the switching lever a is engaged in one of the recesses, the motor vehicle moves forward, and when it is inserted into the other recess, it moves backward. be.

[Problem that the invention seeks to solve]

By the way, when operating the forward/reverse switching lever mentioned above, in the type (■■) mentioned above, you can reach out your hand from the passenger seat and perform the required switching operation at any time, but as in the type (2) above, the passenger seat is operated by the power. If you are away from the car, even if you can perform various driving operations from the passenger seat, you will have to get out of the car each time you operate the forward/reverse switching lever, which is extremely troublesome and inefficient.

In view of the above circumstances, the present invention aims to further improve the benefits by enabling the forward/reverse switching lever provided in the power vehicle to be operated not only directly but also remotely from a passenger seat located away from the power vehicle. shall be.

[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 vehicle is characterized in that an inclined surface is brought into contact with the side portion, and the contact portion between the switching lever and the inclined surface is moved by an auxiliary lever for forward/reverse switching provided on the passenger seat.

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

[Function] With the above structure, when changing the traveling direction of the transport vehicle, the forward/reverse switching lever provided on the power vehicle can be switched by an auxiliary lever from a passenger seat located remotely from the power vehicle. This eliminates the need to get off the train each time you want to change the direction of travel.

〔Example〕

Hereinafter, an embodiment of the present invention will be explained with reference to FIGS. 1 to 3. Reference numeral 1 is a single rail made of a rectangular tube body, and is raised to a predetermined height from the ground by a support 2 (usually about 0.5 to 1.2 meters). At the same time, a rack 3 is installed on the underside of the single rail 1.
are fixed along the length. Reference numeral 4 denotes a power vehicle, and upper wheels 5.5 and lower wheels 6, 6, which move along the single rail 1 while sandwiching the single rail 1 from above and below, are provided at the bottom by being supported by a side frame 7. ing. 8 is an engine mounted on the power vehicle 4, 9 is a transmission case, and 10 is a drive wheel pivotally supported on the side frame 7 so as to mesh with the rack 3. The rotation of the engine 8 causes an interlocking mechanism in the transmission case 9. Drive wheel lO through
The power vehicle 4 is caused to travel on the single rail 1 by being transmitted to the vehicle. 11 is the stop/start lever (throttle lever of engine 8), with the one-dot chain line (position when the automatic stop device is activated while driving forward) and the double-dot chain line (position when the automatic stop device is activated while driving in reverse). When the engine is in the position (position), the engine is in a low-speed rotation state, a centrifugal clutch (not shown) is disengaged, and at the same time, a stop brake (not shown) is in a braking state. When the position is in the solid line, the engine is in a high-speed rotation state, the centrifugal clutch is engaged, and the stop brake is released. In addition to the above, although not shown in the figure, this power vehicle 4 has a constant speed brake that prevents acceleration beyond the specified limit from being applied to the power vehicle, and the constant speed brake, etc. has failed and the power vehicle is about to 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 (trolley) connected to the rear of the power vehicle 4 via a connecting rod 13, and the single rail 1 is sandwiched between the upper and lower portions of the chassis 14 at the front and rear lower portions, and the truck is rolled along the single rail 1. Moving upper wheels 15, 15 and lower wheels 16.16
are provided by being supported by side frames 17, respectively, and run on the single rail 1 by the power vehicle 4. Reference numerals 18 and 18 designate luggage racks erected at the front and rear ends of the vehicle chassis 14, and 19 designates brakes provided at the shaft ends of some of the lower wheels 17.

Although only one cart 12 is shown in the figure, the feature of sequentially connecting two or more carts 12 via a connecting rod is to use the forward/reverse switching lever 20 provided on the power vehicle 4 described above. The purpose is to enable operation from a passenger seat 21 provided at a remote location from the power vehicle 4. In addition, the passenger seat 21 is mounted on the cart 1.
Although an example is shown in which the passenger seat is provided at the extended rear portion of the chassis 14 in FIG.

The passenger seat 21 consists of a seat part 23 disposed laterally on a floor part 22, and a grip rod 2 for the passenger that is erected on the side of this floor part.
4, and a Y-shaped auxiliary lever 25 for stopping/starting which is pivoted to a frame 24' provided on the gripping rod so as to be able to swing back and forth, an auxiliary lever 26 for switching forward and backward, and other parts (not shown) of the cart 12. A control mechanism is provided for operating a brake 19 provided on the lower wheel 17 of the vehicle.

The forward/reverse switching lever 20 described above has its base pivoted on a switching shaft 28 protruding from a part of a machine frame 27 of a motor vehicle, and the lever 20 is attached to a guide groove 30 formed in a guide frame 29.
The traveling direction of the power vehicle 4 can be switched forward or backward by swinging it left and right (back and forth) along the groove and dropping into either of the recesses 30a and 30b provided at both ends of the groove. However, the lever 20 is a bullet (not shown).
Therefore, it is constantly energized in the direction of falling downward into the recess.

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. 2, the protrusion 31 provided between the two recesses is shaped like a mountain, and both sides 31' of the protrusion 31 are inclined surfaces. When the switching lever 20 is pushed toward the other recess 30a in the direction of the arrow (A), the chevron-shaped protrusion slides obliquely upward against the urging force, and the switching lever 20 In order to avoid movement in a direction other than the horizontal movement due to push and pull (diagonal vertical direction) at the time of switching, the guide frame 29 is configured to be moved vertically in a parallel state as shown in FIG. The guide frame 29 may be temporarily lowered by the resistance that the protrusion 31 receives when the switching lever 20 is moved in the left and right linear directions by pushing and pulling.

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. Reference numeral 32 denotes a movable plate that is slidably supported in a groove 33 formed in the machine frame 27 so that it can move left and right in a parallel state at the front part of the guide plate 29. A notch 34 is formed in which the edge 34' is a sloped surface that spreads upward, and the movable plate 32 is moved with the switching lever 20 dropped into the notch 34 and one recess 30b of the guide plate 29. ((2) When moved in the direction of the arrow, the lever is moved upward by one side edge 34' and moved in the direction of the (b) arrow, so that the notch 34 of the switching plate is located at the front of the other recess 30a. When the switching lever 20 is positioned in the downward direction, 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; however, 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 transmission shaft 35 transmits the force of the applied push/pull to the other side, and in the embodiment of the present invention, one end of the transmission shaft 35 is connected to the switching auxiliary lever 26 provided beside the passenger seat 21, and the other end is connected to the second side of the transmission shaft 35. In the example shown in the figure, it is directly pivoted to a tongue piece 36 protruding from one side of the switching lever 20, and in the example shown in FIG. The operation of the auxiliary lever 26 is transmitted to the movable plate 32 via the front and rear attached metal fittings 38.

In addition, in the embodiment of the present invention, the transmission shaft seat 21
It is also provided between the operating end 25' of the auxiliary lever 25 provided at When the lever 11 is moved, the stop/start lever 11 is rotated via the transmission shaft 35' toward the position indicated by the one-dot or two-dot chain line as described above.

According to the above configuration, when the stop/start lever 11 is placed at the solid line position in FIG. 1, the motor vehicle 4 travels in one direction. When the stop-start lever 11 comes into contact with a stopper 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 stops. 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 surface 34' and moved laterally to the other recess 3.
0a, and if the stop-start auxiliary lever 25 is operated as described above, the motor vehicle 4 will move in the opposite direction.

〔Effect of the invention〕

According to the present invention, it is possible to switch the forward/reverse switching lever provided on a power vehicle by operating an auxiliary lever provided on a passenger seat located remote from the power vehicle. The direction of movement of the motive vehicle can be changed at a predetermined end-start position or an intermediate stop position without the need for passengers to get off the vehicle.Moreover, according to the present invention, the above-mentioned forward/reverse switching operation can be performed using a single transmission shaft. As well as being able to do
Since it is also possible to directly operate the forward/reverse switching lever provided on the side of the motor vehicle, the operating efficiency of this type of single-rail transport vehicle can be improved.
