Description

[Detailed description of the invention] The present invention is a power take-off (hereinafter abbreviated as PTO) installed in a four-wheel drive transfer, for example, to drive a winch installed in an automobile.・Regarding the PTO control lever for turning off the vehicle inside the vehicle, the PTO control lever can be folded up when not in use so as not to interfere with driving, and can be locked in the folded state.
Regarding the PTO operating lever.

Specially equipped vehicles such as dump trucks and mixer trucks require power for purposes other than driving.
It is taken out from the PTO attached to the transmission etc.
In addition to the above-mentioned specially equipped vehicles, some four-wheel drive vehicles that are configured to be suitable for off-road driving are used for tasks such as lifting and transporting cargo, and for escaping when stuck. Some models are equipped with a winch to do this, but this one extracts the power for the winch from a so-called transfer PTO attached to the four-wheel drive transfer.

The PTO has a built-in clutch that connects the rotational power of the transmission shaft from the transfer shaft to the output shaft of the PTO, or disconnects the power transmission, and this clutch is connected near the driver's seat via a double wire. It can be turned on and off using the provided PTO control lever.

Incidentally, conventional PTO operating levers have generally been of the rotating arm type, with one end rotatably supported on a floor panel or the like, such as a general handbrake lever.

However, if the PTO operating lever is also a rotating arm type as described above, for example, in a four-wheel drive vehicle equipped with a PTO, the gear shift operating lever, transfer operating lever, handbrake lever, and PTO operating lever are It was called Lever,
A large number of very similar levers are placed close together within a limited area near the driver's seat, which not only takes away from the interior living space, but also makes it difficult for inexperienced drivers to perform various operations. The problem was that it was not possible to immediately judge which lever to select, and if the operation of these levers was interfered with, there was a risk that safety would be compromised.

The present invention was devised under the above circumstances, and the PTO operating lever described above is attached to the front wall of the front seat riser, and when it is not needed, it is removed from the way of driving operations and other lever operations. The purpose of the present invention is to provide a PTO operating lever configured so that it can be folded up so that it does not become erect, and can be raised and operated only when necessary.

In order to achieve the above object, the present invention takes the following technical measures.

That is, in the present invention, a wire attached to the front wall of the front seat riser of the driver's seat and connected to the PTO is pulled through a hole provided in the front wall.
A support plate, which is a lever for operating the PTO, and to which one end of the wire is fixed is fixed to the front wall so as to be rotatable around a support shaft extending approximately parallel to the front wall and in the vehicle width direction. The support plate is pivoted to the bracket, and the tip of the support plate has a
It is pivotably mounted around an axis perpendicular to the support shaft, stands up against the front wall and rotates the support plate, and stands approximately parallel to the front wall in the width direction of the vehicle body. The lever body is provided with a lever body that can take a folded state in which it falls down, and the lever body is fixed to the bracket by engaging the tip of a screw screwed into the bracket so as to be able to move forward and backward into the lever body in the folded state. It is characterized in that it is provided with a fixing means.

The front seat riser is provided at the bottom of the seat, and when the passenger is operating the vehicle, the front wall of the front seat riser, the cabin floor, and the passenger's foot extending to the accelerator or brake pedal are connected. A certain space is formed between them.

This invention focuses on the space in the front wall of the front seat riser, and allows the seat to be folded into this area.
A PTO operating lever is provided. Above PTO
The operating lever is not operated during normal driving, and there is no need to operate it in an emergency, so if the lever body is constantly protruding from the floor, it may actually interfere with driving. do not have. Therefore, in the present invention, the PTO lever is formed into a shape that can be installed on the front wall of the front seat riser, and when not in use, the lever can be folded and stored and fixed under the seat so as not to interfere with driving. This is how it was done.

The lever body in the upright state protrudes forward from the seat riser and is integrated with the support plate to function as an operating lever that can be easily rotated up and down by the occupant sitting on the seat. When the lever body is grasped and rotated to pull it up, the support plate also rotates and the operating wire is pulled forward. Furthermore, when the lever body is rotated downward, the operating wire is returned to the rear. This movement of the wire in the front and back direction allows the clutch in the PTO to be engaged.
It can be turned off.

On the other hand, when the lever body is folded and rotated with respect to the support plate, the lever body is folded and stored along the front wall of the seat riser. In this state, the lever body no longer protrudes from the front wall of the seat riser, so it does not get in the way of the feet of the occupant sitting on the seat, and it also prevents the lever body from interfering with the footwells of passengers seated on the seat. It is safe because there is no chance of accidently operating the lever. Also, if the seat riser is in an upright position protruding forward from the front wall, it will get in the way of the occupant's feet, so when it is not needed, remember to store the lever body in the folded state as above, so from this aspect Accidents caused by accidentally operating the PTO control lever when it is not necessary can be almost completely avoided.

Moreover, in the present invention, since a fixing means is provided for fixing the lever body in the folded state with a screw, the lever body can be moved in either the upright/folding direction or the wire pulling/feeding direction. can also be fixed to prevent accidental rotation, further increasing safety when the PTO operating lever is not required.

As described above, according to the PTO operation lever of the present invention, when the lever body is in the upright state, the lever body protrudes forward from the front wall of the seat riser, so it is very difficult for the occupant sitting in the driver's seat to operate the PTO. While the ease of operation has improved, the PTO
When it is not needed, remember to fold the lever body as it will get in the way of driving if it remains in the upright position.Moreover, in the folded state, the lever body will fit along the front wall of the seat riser, making it easy to use when driving a car. The lever body is stored in such a way that there is no hindrance to the operation of the lever, and furthermore, in the stored state, the lever body can be securely fixed by the screw fixing means, thereby increasing safety.

Embodiments of the present invention will be specifically described below with reference to the drawings.

Figure 1 shows an example of a four-wheel drive van type vehicle in which power is extracted from the transfer PTO to operate the winch.

First, the overall configuration of the PTO in this example, the winch operated by the PTO, and the operating system thereof will be explained.

In this type of van type vehicle, the engine 1 is located under the floor in the center of the vehicle body, the transmission 2 is located at the rear of the engine, and the four-wheel drive transmission 3 is located at the rear of the engine.
will be placed. The front wall of the transfer 3 faces an output shaft 4 for driving the front wheels, and the rear wall faces the output shaft 5 for driving the rear wheels.
are connected to a front wheel actuating device 6 and a rear wheel actuating device 7 by drive shafts 8 and 9, respectively. This transfer 3 transfers the rotational power of a transmission shaft from the transmission 2 to an output shaft for driving rear wheels by a transfer operation lever 10 disposed near the driver's seat via a wire W1 such as a double wire. It is possible to select whether to transmit the signal only to the rear wheel drive output shaft 5 or to both the rear wheel drive output shaft and the front wheel drive output shaft 4.

There is also a PTO 1 on the rear of the transfer 3 above.
1 is installed, and its output shaft 12 is
It is connected by a drive shaft 14 to a winch 13 mounted under the floor in the further direction of the PTO 11. This PTO11 has an internal clutch (not shown) installed near the driver's seat.
Using the PTO operating lever 15, the operating wire W2
It is possible to turn it on and off by operating it through the . To operate the winch 13, operate the transmission control lever 16 to shift the transmission to, for example, low gear.
It is sufficient to rotate the PTO operating lever 15 to the "on" side. In addition, in FIG. 1, the reference numeral 17 refers to the above
An operating system is shown that is connected to the PTO operating lever 15 and that automatically releases the PTO clutch by detecting the winding end of the winch cable.

The PTO operating lever of the present invention is attached to the front wall of the front seat riser 18 below the front seat, as shown in FIG. The front wall of the front seat riser is located below the seat, and a certain space is formed between the floor of the vehicle interior and the front wall. This invention focuses on the above-mentioned space from the viewpoint of operability and safety.
A PTO lever device is provided.

2 to 4 show details of the PTO operating lever attached to the front wall of the front seat riser 18.

A bracket 20 having a vertical wall 19 extending forward is fixed to the front wall of the seat riser 18.
The support plate 22 is connected to the support shaft 21 supported by the vertical wall 19 so as to extend substantially parallel to the front wall of the seat riser 18 and in the vehicle width direction.
is rotatably mounted. As shown in FIG. 3, this support plate 22 is formed by bending a plate material into a substantially U-shape, and is formed by bending the plate material into a substantially U-shape.
It is rotatably attached to this vertical wall 19 so as to sandwich it therebetween. This is advantageous because the support plate 22 can be vertically rotated without rattling laterally relative to the vertical wall of the bracket 20. In addition, the second
As shown in the figure, this support plate 22
One end of an operating wire W2 pulled out from a hole 23 formed in the seat riser 18 is coupled to the lower extension of the seat riser 18.

On the other hand, a shaft 25 is attached to the cylindrical bent part 24 formed at the front end of the support plate 22 so as to fit into this part, and the middle part of the front edge of the support plate 22 including this bent part is cut. The shaft 25 is cut out to expose the shaft 25, and the base of the lever body 26 is attached to this. When the shaft 25 is fixed to the support plate 22,
When the lever body 26 is rotatably supported on the shaft 25 and the shaft 25 and the lever body 26 are fixed to each other, the shaft 25 is rotatably supported on the support plate 22. Therefore, the lever main body 26 has a shaft 2 located in a vertical plane extending in the front-rear direction.
It becomes possible to rotate laterally with respect to 5.

In the illustrated example, the pivoting end of the lever body 26 relative to the support plate 22 is placed in an upright state extending vertically forward from the seat riser in a plan view, and in a folded state in which it is located parallel to the seat riser in a plan view. A regulating means 27 is provided for regulating the condition. As clearly shown in FIG. 3, the regulating means 27 includes a planar outer abutting surface 28 and a rear abutting surface located at the same distance from the shaft 25 and perpendicular to each other at the base end of the lever body 26. A plate spring 31 is fixed to the bracket 20, and has a planar action portion 30 that forms a contact surface 29 and can elastically contact the contact surfaces 28 and 29. According to this regulating means, the acting portion 30 and the outer abutting surface 28 or the acting portion 30 and the rear abutting surface 29 come into surface contact with each other, and the elasticity of the leaf spring 31 is released to the maximum. The lever main body 26 is stably held in the upright state shown by solid lines in FIG. 3 and in the folded state shown by phantom lines. In the illustrated example, since the outer contact surface 28 and the rear contact surface 29 are perpendicular to each other, the angle between the upright state and the folded state of the lever body 26 is 90 degrees.
Further, the lever body 26 is elastically biased by the leaf spring 31 in a so-called fulcrum over type, so that when the lever body 26 is rotated to the upright state or close to the folded state, it automatically rotates. It rotates in the direction you want to move it into an upright or folded state. Note that this regulating means is not limited to the configuration shown in the drawings, and may, for example, elastically engage a recess formed on the upper surface of the lever body in the upright state and the folded state to control the rotational position of the lever body. A notch ball (not shown) that can be held may be embedded in a member corresponding to the support plate 22, or a simple stopper may be provided.

Further, a branch piece 32 is provided inside the bracket 20 and extends along and opposite to the upper surface of the lever body 26 in the folded state, and a screw hole 35 provided in the branch piece 32 is inserted into the upper surface of the lever body 26. A fixing means 36 for fixing the lever main body 26 in a folded state by screwing in a thumbscrew 34, for example, having a tip shaft portion that can engage with the formed concave hole 33;
has been configured. By doing this,
When there is no need to use the PTO 11, fold the lever body 26 and
4 is fixed to the bracket along the front wall of the front seat riser 18 by engaging the tip of the lever with the concave hole 33 of the lever.
Inconveniences such as when the lever main body 26 wobbles or is inadvertently rotated toward the upright side due to vibration or the like can be avoided.

How to operate the PTO operating lever with the above configuration is as follows.
It is as follows.

First, the lever main body 26, which is folded and fixed as shown by the imaginary line in FIG.
6 to be able to rotate laterally with respect to the support plate 22, and then rotated upright as shown by the solid line in FIG. At this time, the third
As shown in the figure, since the lever main body 26 does not interfere with the support piece 32 provided with the fixing means 36, the lever main body 26 and the support plate 22 supporting the lever main body 26 can be moved in the vertical direction about the support shaft 21 of the bracket 20. It becomes possible to rotate. As shown in FIG. 2, when the lever body 26 is grasped and pulled upward, the lever body 26 or the support plate 22
rotates as shown by the imaginary line in FIG. 2, and at this time the wire W2 whose end is connected to the lower part of the support plate 22 is pulled. Conversely, when the lever main body 26 is rotated downward from the state shown by the imaginary line as shown by the solid line, the wire W2 is pushed. This wire W2 is as shown in Figure 1.
It is connected to the PTO, so the PTO 11 can be turned on and off by operating the lever described above.

As described above, according to the PTO operation lever of the present invention, when the lever body is in the upright state, the lever body protrudes forward from the front wall of the seat riser, so it is very difficult for the occupant sitting in the driver's seat to operate the PTO. While the ease of operation has improved, the PTO
When it is not needed, remember to fold the lever body as it will get in the way of driving if it remains in the upright position.Moreover, in the folded state, the lever body will fit along the front wall of the seat riser, making it easy to use when driving a car. The lever body is stored in such a way that there is no hindrance to the operation of the lever, and furthermore, in the stored state, the lever body can be securely fixed by the screw fixing means, thereby increasing safety.

Note that the scope of the present invention is not limited to the above embodiments. The shapes of the bracket, support plate and lever body can be changed in various ways as required.
