Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a shutter curtain device that adjusts the amount of ventilation in a radiator for a rear engine bus. More specifically, the present invention relates to a device that allows a shutter curtain to be easily operated from the rear of a bus.

Particularly in large automobiles, an intake shutter curtain is usually installed in front of the radiator in order to adjust the amount of air taken into the radiator during the winter.
In the case of a rear engine bus, the radiator is usually mounted on the rear side of the vehicle, and the curtain is operated by opening and closing an inspection door on the side of the vehicle. However, this type of operation has the following various drawbacks depending on the specifications of the vehicle. FIG. 1 is a schematic plan view of the rear part of a conventional rear engine bus. An engine 2 and a radiator 3 are mounted on the rear side of the vehicle body 1. A fan 5 is driven by the engine 2 through a V-belt 4, and the radiator It is configured to take in air at 3. An inspection door 6 is attached to the side of the vehicle body 1 so as to be openable and closable. A shutter curtain 7 is attached to open and close the front surface of the radiator 3.

Therefore, when opening/closing the shutter curtain 7 at the time of the vehicle start-up inspection, the inspection door 6 is opened.
In many cases, the inspection door 6 cannot be opened sufficiently because the inspection door 6 may interfere with an adjacent vehicle.

Further, as shown in FIG. 2, if there is a sound insulating device 8 such as a sound absorbing duct or a storage space in front of the radiator 3, it is troublesome to operate the curtain 7 itself.

Another problem is that when the radiator 3 is mounted on the right side of the vehicle, when the driver operates the curtain 7 on the road, he opens the inspection door 6 on the right side, which is often dangerous.

The above drawback is due to the structure in which the shutter curtain in front of the radiator is manually operated directly from the inspection door side, and the present invention provides a structure that eliminates this drawback.

In order to achieve the above object, the configuration of the present invention is such that a working door is provided at the rear end of an undercover that forms a storage chamber for a radiator provided at the rear of a rear engine bus, and a work door is provided in a manner that can be opened and closed, and a shutter provided in the front of the radiator is provided. The present invention is characterized in that the rope for operating the tar curtain can be operated by opening the work door.

Next, embodiments of the present invention will be described with reference to the drawings. 3 to 5, a radiator 3 is housed in a space 11 between an undercover 9 and an upper cover 10 of the rear engine bus, and a shutter curtain 7 is mounted on a reel 7a in front of the radiator 3. The rope 12 is arranged to be wound around the rope 12 and unwound by the rope 12. A rope 12 is pulled out below the shutter curtain 7 and guided by rollers 13, and is guided by an undercover 9.
The rope 12 is fixed by hooking a knot 12a provided on the rope 12 itself to a hook 15 fixed near the opening 16a for the work door 9a, which is provided at the rear end, that is, below the rear bumper 14 so as to be openable and closable. .
Further, a hole 18 is provided in the lower rear panel of the bus rear door 16 to engage with a stopper 17 of the work door 9a, so that the work door 9a is fixed. The stopper 17 can be rotated integrally with the opening/closing knob 9b of the work door 9a.

The above-mentioned rope 12 is guided by the roller 13 and hooked with the knot 12a on the hook 15 of the undercover 9 to determine the opening degree of the shutter curtain 7. Just wrap it around the hook 19. In this way, the pulled out part of the rope 12 is connected to the work door 9a.
Although it is configured to be locked to a hook 15 provided on a nearby undercover 9, another winding hook 19 may be provided on the same cover 9 and used to wind up the excess rope 12. .

In the present invention, a working door 9a is provided at the rear of the undercover 9 below the radiator 3, preferably under the rear bumper 14, and the undercover 9 is further provided with a working door 9a.
Place the hook 1 near the opening 6a of the work door 9a.
5 is fixed, a rope 12 connected to the shutter curtain 7 can be locked thereto, the work door 9a is opened from the rear of the vehicle, and the rope is operated to open the shutter curtain. The feature is that the opening degree of 7 can be adjusted.

Therefore, according to the present invention, the opening degree of the shutter curtain 7 can be easily adjusted by opening the work door 9a below the bumper and operating the rope 12 there. After all, according to the present invention, there is no need to insert a hand or the like into the front of the radiator 3 when opening and closing the shutter curtain 7, so there is no need to open and close the door 6 on the side of the vehicle.
The drawbacks of the conventional device as described above can be completely avoided, and it can also be implemented without problems even in vehicles equipped with a noise reduction device such as a noise reduction duct 8 on the front of the radiator 3.

Rope 12 and undercover 9 in the present invention
Although it has been explained that the locking is done by the knot of the rope 12 and the hook 15 of the undercover 9,
This locking means is not limited to this, and the gist of the present invention can be achieved with any type of locking means.
