An open / close door with a packing is provided to prevent scattering of sewage and odors from the opening, and the open / close door attached to the packing box may impair maintainability. It was designed so that it would not exist.

That is, FIG. 8 is an overall side view of the refuse collection vehicle, and FIG. 9 is a plan view of the same. A luggage box 3 is mounted on a chassis frame 2 extending rearward from the cab 1, and the luggage box 3 A tailgate 4 having a loading device (not shown) built therein is rotatably supported by a hinge 5 and connected to the rear opening. Inside the cargo box 3, a discharge plate 6 for forcibly discharging the dust collected therein is incorporated so as to be slidable in the front-rear direction.

Accordingly, in order to discharge the dust loaded in the cargo box 3, the tailgate 4 is rotated upward to the position shown by the phantom line in FIG. 8, and then the discharge plate 6 is arranged at the rear of the vehicle. It is configured to do this by sliding backwards to the position shown in phantom.

A double-sided open / close door 7 is provided on the front surface of the luggage box 3 to open and close the inspection opening 3a provided therein. The configuration of each open / close door 7 is as follows. Will be described below.

1 and 2 are cross-sectional views taken along the line AA of FIG. 7 showing the front surface of the packing box 3. FIG. 1 shows a state in which the opening / closing door 7 is open to the side of the vehicle, and FIG. Are shown respectively.

Inside the opening / closing door 7, the ends of a U-shaped arm 8 formed by bending a rod-shaped body in a U-shape and an L-shaped arm 9 formed by bending a rod member in an L-shape are pin 10, It is rotatably connected via 11. Here, the connecting point (pin 10) of the U-shaped arm 8 is located near the center of the opening / closing door 7, and the connecting point (pin 11) of the L-shaped arm 9 is located near the wall of the packing box 3. It is like being located.

A first bracket 12 and a second racket 13 are fixed to the inner surface of the front part of the luggage box 3, and the U-shaped arm 8 and the L-shaped arm 9 are attached to the brackets 12 and 13, respectively. The other end is rotatably connected via hinges 14 and 15. Here, the connecting point (hinge 14) of the U-shaped arm 8 is located in front of the vehicle than the connecting point (hinge 15) of the L-shaped arm 9.

Thus, the luggage box 3, the opening / closing door 7 and the two arms 8 and 9 constitute a four-bar rotary chain mechanism, and the opening / closing door 7 connects the hinges 14 and 15 of the two arms 8 and 9. While swinging around the center, it gradually rotates and moves from the front of the vehicle to the sides to open and close. As a result, the opening / closing door 7 can be opened and closed with a smaller width, that is, within the range of the distance W between the front surface of the packing box 3 and the cab 1, and the U-shaped arm 8 and the L-shaped arm 9 are used. As a result, both arms 8 and 9 are prevented from interfering with the side end faces of the luggage box 3 when the opening / closing door 7 is opened / closed.

As shown in FIGS. 3 and 7, the U-shaped arm 8 is provided at two locations in the upper and lower directions of the opening / closing door 7. This is to prevent the opening / closing door 7 from being shaken in the vertical direction. That is, if the pair of U-shaped arms 8 and L-shaped arms 9 are provided below the opening / closing door 7 as described above, the movement of the points X and Y in FIG. 7 can be ensured. The movement of the point U in the figure may be blurred. Therefore, by further providing another U-shaped arm 8 as described above, the movement of this point U can be ensured.

A packing 16 is provided on the inner surface of the peripheral portion of the opening / closing door 7 so as to be bent in a substantially U shape (see FIG. 6), so that when the opening / closing door 7 is closed, the packing 16 is provided. The packing box 3 is in close contact with the front end surface of the packing box 3 to prevent leakage of sewage from the inspection opening 3a.

In this embodiment, in order to ensure the opening / closing operation of the opening / closing door 7, another slide mechanism is provided. This is shown in FIGS. Here, FIG. 4 shows a state in which the opening / closing door 7 is closed, FIG. 5 shows a state in which it is opened to the side of the vehicle, and FIG.

That is, since the upper portion of the opening / closing door 7 is close to the discharge plate 6 and the distance H between the two is considerably short, it is not possible to adopt the above-described configuration using the arms 8 and 9. For this reason, a slide mechanism using the guide rail 17 is provided on the upper part of the opening / closing door 7 in order to ensure the movement of the point Z in FIG.

This mechanism includes a guide rail 17 provided on the upper end surface of the packing box 3 along the width direction of the packing box 3 and two types of moving guide rails 17 that rotate in the guide rails 17 in directions orthogonal to each other. It mainly comprises a roller hinge 20 having rollers 18 and 19 at one end, and an auxiliary arm 21 connecting the projecting end of the roller hinge 20 and the central upper portion of the opening / closing door 7.

The one roller 18 is provided along the lengthwise direction of the guide rail 17 so as to restrict the left and right blurring of the roller hinge 20, and is orthogonal to the roller 18. The other roller 19 which rotates in the direction of rotation is designed to regulate the movement only in the downward direction.

The roller hinge 20 and one end of the auxiliary arm 21 are rotatably connected via a hinge 22, and the other end of the auxiliary arm 21 is rotatably connected to the opening / closing door 7 via a pin 23. ing.

The locus S of the pin 23 is the same as the locus of the pin 11, so that the roller hinge 20 and the auxiliary arm 21 operate in accordance with the movement of the pin 11. That is, the roller hinge 20 and the auxiliary arm 21 and the like supplementarily restrain the movement of the point Z 1 in FIG. 7, and prevent the pin 10, 11 and the like from rattling at the point Z 1.

Therefore, the guide rail 17 and the roller hinge 20 can be eliminated, but in that case, the rigidity of the opening / closing door 7 and the arms 8 and 9 is increased to prevent the point Z from rattling. There is a need.

FIGS. 10 to 17 show a second embodiment, in which an opening / closing door with two foldable packings provided with two parallel support links is provided on the front surface of the packing box 3 to prevent sewage. In addition to preventing the scattering and leakage of foul odors, the opening / closing door attached to the packing box prevents the maintenance performance from being impaired.

One end of a substantially L-shaped support link 33 is fixed to the outer edge of one of the panels 30 b located on the outer side, and the other end of the support link 33 has a pin 34 and a packing box. It is rotatably connected to the outer side surface of 3. In the illustrated embodiment, each opening / closing door 30 is provided with two supporting links 33, but it is needless to say that three or more supporting links 33 may be provided.

Further, guide rails 35 extending in the width direction are provided on both upper and lower end surfaces of the packing box 3, and at the upper and lower sides on the center side of the inner panel 30 a forming the opening / closing door 30, this guide rail 35 is provided. A guide roller 36 is arranged to move inside the guide rail 35 as a guide.

Further, similarly to the first embodiment described above, the packing 16 is provided on the inner surface of the peripheral edge portion of the opening / closing door 30 so as to be bent in a substantially U shape, thereby closing the opening / closing door 30. At this time, the packing 16 is brought into close contact with the front end face of the luggage box 3 to prevent leakage of dirty water from the inspection opening 3a.

As described above, by forming the opening / closing door 30 with the two foldable panels 30a and 30b, it is possible to slide the opening / closing door 30 laterally and open the opening / closing door 30. That is, the opening / closing door 7 can be opened and closed within the range of the distance W between the front of the packing box 3 and the cab 1. As a result, the loadability of the opening / closing door 30 on the chassis 2 can be improved. The guide roller 36 is for smoothing the movement of the opening / closing door 30 along the front surface of the luggage box 3.

The opening / closing door 30 is provided with a lock device 37 for fixing the opening / closing door 30 to the luggage box 3 when closed.

That is, as shown in detail in FIGS. 15 and 16, the lock mechanism 37 is rotatably held in the opening window 30c provided in the opening / closing door 30 via the pin 38 in the direction of pulling toward the front of the vehicle. The handle 39 is mainly composed of a handle 39, a coil spring 40 biasing the handle 39 in the opposite direction to the above, and a lock rod 41 extending vertically from the handle 39. Then, a central rod 43 positioned behind the handle 39 and abutting against the handle 39 and linearly connected via the lock rod 41 and a connecting rod 42 is arranged, and the upper and lower ends of the lock rod 41 are arranged. A lock hole (not shown) is provided on the peripheral wall of the packing box 3 corresponding to the section.

As a result, by pulling the handle 39 forward, the central rod 41 abutting against the handle 39 is pushed rearward and moved, whereby the lock rod 41 is contracted via the connecting rod 42 to move the lock rod 41. The engagement between the end and the lock hole is released, the lock is released by this, and the central rod 41 is returned to the original position by the elastic force of the coil spring 40, and the lock rod 41 is extended through the connecting rod 42. By inserting this end portion into the lock hole, the opening / closing door 30 is locked to the luggage box 3.
