2. Description of the Related Art FIG. 6 shows an example of a structure of a rear portion 52 of a conventional garbage truck 51. A slide cover 1 is attached to an opening of a tailgate 53 of a rear portion 52 of the garbage box 51 of the refuse collecting vehicle 51. When collecting the refuse, an operator, as shown by a chain double-dashed line in FIG. The slide cover 1 is opened, and the collected dust is put into the packing box from here. The slide cover 1 is closed when the vehicle moves.

This slide cover 1 is shown in FIGS. 7 and 8.
As shown in Fig. 3, the rolled stainless steel plate is formed into a "V" shape, and has a predetermined width on both side edges parallel to each side edge and perpendicular to the plate surface of the slide cover 1. The reinforcing member 2 is provided.

As shown in FIG. 7, fixed pins 3 projecting outward in the horizontal direction are provided at both ends of the upper edge of the slide cover 1, and each fixed pin 3 has a "head" as shown in FIG. It is rotatably attached to one end of an arm 4 having a V shape. The other end of the arm 4 is rotatably attached to a rotary shaft 5 on the vehicle body side. Then, as shown in FIG. 7, the other end of the tension spring 6 having one end hooked to the front part of the vehicle is connected to the "V-shaped" vehicle front side upper surface of the arm 4, The spring 6 constantly urges the arm 4 to pull forward around the rotation shaft 5. Therefore, the slide cover 1 attached to the arm 4 is also always urged so as to be pulled forward and upward.

Below the both side edges of the slide cover 1 is shown in FIG.
10 to 10, a roller shaft 8 to which a roller 7 for sliding the slide cover 1 is attached is attached.

The roller shaft 8 is supported by a bearing unit 60 fixed to the inner surface of the slide cover 1, and is mounted so as to be slidable parallel to the plate surface of the slide cover 1 and horizontally.

The outer end of each roller shaft 8 projects from a hole provided in the reinforcing member 2, and the projecting portion has
A roller 7 is slidably fitted along the roller shaft 8.

On the other hand, as shown in FIG. 9, the side pillar 54 of the tailgate has a U-shaped horizontal cross section, and its opening surface faces the inside of the tailgate 53. Has been done. The roller 7 is fitted on the side pillar 54, and when the slide cover 1 is opened and closed, the roller 7 rolls along the inner wall of the side pillar 54, and the slide cover 1 is fitted on both side pillars of the tailgate. It can slide smoothly along 54, 54.

A spring 57 is fitted between the stepped portion 55 of the roller shaft 8 and the side plate 56 of the bearing unit 60 so that the roller shaft 8 is always urged outward.

At the positions where the axial center of the roller shaft 8 intersects with the side pillars 54 of the tailgate 53 when the slide cover 1 is completely closed and completely opened, the side pillars are respectively located. Opposing wall 59 of the opening surface of 54
A fixing hole 58 having a diameter into which the end of the roller shaft 8 can be inserted,
58 is provided, and in each state where the slide cover 1 is completely opened and closed, the roller shaft 8 slides outward due to the urging force of the spring 57, and the roller 7 remains restrained in the side column 54. The end of the roller shaft 8 passes through the inside of the roller 7 and is inserted into the fixing hole 58, so that the slide cover 1 is fixed.

In order to release this fixed state, the roller shaft 8 must be slid inward against the urging force of the spring 57, and the end of the roller shaft 8 must be pulled out from the fixing hole 58 of the side column 54. The slide mechanism of the roller shaft 8 provided for that purpose, that is, the lock (and release) mechanism of the slide cover 1 will be described below.

At the inner end of the roller shaft 8, a link mechanism 4 including two members 41 and 42 as shown in FIG.

[0014]

By the way, the dust collecting vehicle 51 provided with the lock mechanism for the slide cover 1 having the above-described structure has the following problems.

That is, when the slide cover 1 is opened, the lever 44 of the lock mechanism is located above the opening of the tailgate, and the operator places his / her foot on the protrusion or the like at the rear of the luggage carrier and rides on the vehicle. When the operator takes the position of the lever 44 and the supporting rod 45, the operator holds the lever 44 or the supporting rod 45 and is still riding on the garbage collecting vehicle 51.
If you move the car at a slow speed, you will be in a position that will not hinder you from taking a stable figure. Moreover, this garbage truck 51 has a short travel distance from one collecting place to the next collecting place.

Therefore, there is a case where an operator holds the slide cover 1 open, holds the slide cover 1 by the lever 44 or the supporting rod 45 of the lock mechanism, rides on the vehicle, and moves as it is.

However, even though the speed of the vehicle is slow and the distance traveled is short, it is, of course, extremely dangerous for the operator to ride the vehicle in the above-described manner and move as it is. . Further, if the vehicle is moved while the slide cover 1 is open, the dust in the luggage box may fly out.

Therefore, an object of the present invention is to provide a structure in which the operating means of the lock mechanism at the time of opening and closing the slide cover of the tailgate opening provided at the rear of the luggage box of the refuse collection vehicle does not come out to the outside of the slide cover. The purpose of the present invention is to provide a slide cover for a garbage truck so as to prevent the worker from performing the above dangerous actions.

[0019]

In order to solve the above-mentioned problems, a first aspect of the present invention comprises a lock mechanism inside a slide cover provided at a tailgate opening of a dust container truck, and The lock mechanism swings an open housing toward an opening provided in the slide cover and a locking portion including a fixing member and an engaging member that locks between the fixed positions of the slide cover and the luggage box. The lock releasing portion is provided freely and is fixed to the housing, and has a pressing member for pressing the engaging member to unlock the engaging member.

In this slide cover, by inserting a hand through the opening and swinging the casing up and down, the pressing member fixed to the casing presses the engagement member, and the engagement is performed. The locking or unlocking of the fixed member that engages with the member is performed. This allows the slide cover to be locked and unlocked.

A second aspect of the present invention is the slide cover of the refuse collecting vehicle of the first aspect, wherein the engaging member is rotatably attached to a bracket provided on the inner surface of the slide cover, and the urging means is provided. The lock member is urged to engage with the fixing member, and the lock is released by inserting a hand into the housing through an opening provided in the slide cover and swinging the housing.
