BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an external view of a trailer provided with a taillight mechanism according to the present invention. The trailer 1 has a loading platform 1A large enough to mount an agricultural machine mounted on a chassis 2 (see FIG. 2). The towing member 1B provided in front of the vehicle is hung by a towing member provided on a towing vehicle 3 such as a truck to be towed. At the rear of the vehicle body of the trailer 1, a tail light 5 described later is provided.
Is arranged.

FIG. 2 is a side view showing a lower rear portion of the loading platform 1A. In the drawing, the loading platform 1A selects between a horizontal state and a tilting state via a support shaft 4 provided on a chassis 2 forming a vehicle body. Supported to be able. A tail light 5 that can be raised and lowered with respect to the surface of the loading platform 1A is provided in the lower portion of the loading platform 1A and near the rear end. The taillight 5 is supported by a taillight mounting portion 6A provided on a lamp bracket 6 having a plate member 6B capable of covering an upper portion of the taillight 5.

The front end of the trailer 1 on the vehicle body front side (the side indicated by the symbol F in FIGS. 1 and 2) of the trailer 1 is integrated with a swing lever 7 to be described later, and the lamp bracket 6 is positioned on the surface of the loading platform 1A. It is provided to be able to undulate. The swing lever 7 is pivotally supported by a base shaft 8 provided on the loading platform 1A, and the lamp bracket 6 is attached to a swing end. The swinging end of the swinging lever 7 is connected to one end in the extension direction of a pulling wire 9 serving as a connecting member.

The pulling wire 9 is connected to a spring 11 which is an elastic body, while bypassing a roller 10 provided on the loading platform 1A. The other end of the spring 110 is fixed to one end of the adjustment bolt 13 fastened to the bracket 12 fixed to the chassis 2, and has a habit of expanding the pulling wire 9 except at the time of maximum contraction. Thus, the swing lever 7 can swing clockwise in FIG. The roller 10 is installed at a position higher than the support shaft 4 of the carrier 1A when the carrier 1A is in the horizontal state, and at the same position as or lower than the support shaft 4 when the carrier 1A is tilted. It is positioned as follows. By setting the installation position of the roller 10, the tension of the pulling wire 9 is changed by changing the amount of expansion and contraction of the spring 11 connected to the end of the pulling wire 9 bypassing the roller 10. . The tension of the pulling wire 9 when the carrier 1A is in a horizontal state is adjusted by the amount of advance and retreat of the adjusting screw 13 on the side to which one end of the spring 11 is connected. Such adjustment is performed to set the standing state of the lamp bracket 6 and is performed to apply to the pulling wire 9 a tension that allows the taillight 5 to be exposed from the surface of the loading platform 1A.

Since the present embodiment is configured as described above,
When the bed 1A is in the horizontal state, the state shown in FIG. 2 is set. That is, when the swinging lever 7 swings clockwise due to the extension of the pulling wire 9 due to the habit of the spring 11, the lamp bracket 6 rises from the surface of the loading platform 1A in conjunction with the swinging lever 7, and the taillight 5 is moved. It is exposed to the outside. The lamp bracket 6 in the raised state is
As long as the bed 1A is in the horizontal state, the extension of the pulling wire 9 is maintained, so that the taillight 5 can satisfactorily warn the following vehicle.

On the other hand, when the bed 1A is tilted, the state shown in FIG. 3 is obtained. In other words, when the loading platform 1A is tilted, the height of the roller 10 around which the traction wire 9 is detoured decreases, and the spring 11 contracts maximally due to the decrease in the distance between the roller 10 and the adjustment screw 13, and further traction is performed. The wire 9 will not be pulled. For this reason, the pulling wire 9 which has been in the extended state is loosened, and the swing lever 7 is allowed to swing freely.
Thus, the lamp bracket 6 can swing using its own weight in the counterclockwise direction, which is the opposite direction to the swing direction that has been regulated, so that the tail lamp 5 is turned down below the loading platform 2. be able to. When the tail light 5 is in a prone state, the plate member 6B of the lamp bracket 6 is connected to the loading platform 1A.
A part of the surface. Thereby, since the taillight 5 can be prevented from becoming a protrusion on the surface of the loading platform 1A, it is possible to easily carry in and out of the agricultural work machine.

Next, another embodiment of the present invention will be described with reference to FIGS. 4 and 5, the same components as those shown in FIG. 2 are denoted by the same reference numerals. The embodiment shown in FIGS.
The habit of always accommodating the lamp bracket 20 under the carrier 1A is imparted to the lamp bracket 20 to which is attached, and the lamp bracket 20 is towed when the carrier 1A is set in a horizontal state against this habit. , So that the lamp bracket 20 is exposed below the loading platform. That is, FIG. 4 shows a case where the loading platform 1A is in a horizontal state, and in FIG.
Reference numeral 0 denotes a mounting portion 20A for the tail light 5 provided at the rear end in the front-rear direction of the vehicle body, and a swing lever 21 and a pulling wire 9 provided at the front end.
Is provided at one end in the extension direction. Lamp bracket 2
0 is rotatably supported by the chassis 2 around a point where the swing lever 21 is disposed as a fulcrum.
It is integrated with. The swing lever 21 can be interlocked with the lamp bracket 20 by integrating the base end thereof with the lamp bracket 20.
And a return spring 22 bridged between them.
The return spring 22 has a habit of rotating the swing lever 21 clockwise in FIG. 4 so that the lamp bracket 20 is always accommodated in the lower part of the carrier 2.

Below the fulcrum of the lamp bracket 20, one end of the pulling wire 9 is connected. As in the embodiment shown in FIG.
0 and is connected to the spring 11. In this case, the connection position between the pulling wire 9 and the lamp bracket 20 is:
The lamp bracket 20 resists the clockwise rotation of the lamp bracket 20 caused by the return spring 22.
Is positioned at a position where it can be rotated counterclockwise.

Since the present embodiment has the above configuration,
When the bed 1A is in the horizontal state, the state is as shown in FIG. That is, when the pulling wire 9 is expanded by the habit of the spring 11, the return bracket 22 rotates the lamp bracket 20 which is about to rotate clockwise in the counterclockwise direction. As a result, the lamp bracket 20 raises the lamp mounting portion 20A downward of the carrier 1A, and
To the outside. In the lamp bracket 20 raised below the loading platform 1A, the extension of the pulling wire 9 is maintained as long as the loading platform 1A is in a horizontal state, so that the taillight 5 can give a good warning to the following vehicle. .

On the other hand, when the bed 1A is tilted, the state shown in FIG. 5 is obtained. That is, when the carrier 1A is tilted, the height of the roller 10 around which the traction wire 9 is detoured is reduced, and the distance between the roller 9 and the adjustment screw 11 is reduced, so that the spring 11 contracts to the maximum, and further traction is performed. The wire 9 will not be pulled. For this reason, the pulling wire 9 which has been in the extended state is loosened, and the swing lever 7 is allowed to swing freely. Accordingly, the swing lever 21 is moved by the habit of the return spring 22.
Can be rotated clockwise, so that the lamp bracket 20 is accommodated in the lower part of the loading platform 1A in conjunction with this. When the lamp bracket 20 is accommodated in the lower portion of the loading platform 1A and the tail lamp 5 is retracted from the outside, there is no member that protrudes outward from the lower portion of the loading platform 1A.
The situation where the taillight 5 is damaged when A is tilted is eliminated.

As described above, according to the first and second aspects of the present invention, when the bed of the trailer is horizontal to the vehicle body, the taillight is pulled by the connecting member so as to protrude above the bed, and when the trailer is tilted. Since the vehicle is accommodated in the cargo bed, the taillight does not become a hindrance when the agricultural work machine enters or exits, and it is also possible to satisfactorily warn the following vehicle during traveling. In particular, the connecting member is a pulling wire, and when the loading platform is horizontal to the vehicle body, the loading platform is separated from the vehicle body, so that the pulling wire connected at one end to the vehicle body is pulled, and the tail light is generated by the attractive force. . In addition, when the carrier is tilted, the carrier approaches the vehicle body, so that the pulling force of the pulling wire is loosened, and the taillight is laid down by the elastic force so as to be accommodated in the carrier. With a simple configuration that is linked to the setting of the horizontal and tilting states of the loading platform without the need for
This makes it possible to ensure safety during traveling and simplify the work of mounting on a carrier.

According to the third and fourth aspects of the present invention, when the taillight is provided on the lower surface of the loading platform, the taillight is urged by the elastic force of the elastic body so as to be always held upward, that is, housed in the loading platform. Have been. When the carrier is horizontal with respect to the vehicle body, the taillight is generated below the carrier due to the attractive force of the connecting member (traction wire), and the attractive force of the connecting member (traction wire) is loosened when the carrier tilts. Since the taillight is laid down by the elastic force so as to be accommodated in the loading platform, the configuration required for raising and lowering the taillight does not need to be a configuration requiring a special driving source, and it can be used in any of the horizontal and tilting states of the loading platform. By simply adopting a simple structure that is linked only, particularly when the bed is tilted, it is possible to prevent the tail light that has occurred up to that time from being turned down and prevent the damage due to the tilt of the bed.
