Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a conveyor mounted on the floor of a cargo compartment of a truck, and a partition which reciprocates in the cargo compartment together with the conveyor, and moves smoothly in the cargo compartment at all times. The present invention relates to a truck cabin partition structure which can sufficiently withstand the impact of collapse of cargo.

[0002]

2. Description of the Related Art In recent years, there has been a truck in which a conveyor device is mounted on the floor of a cargo compartment of a truck so that cargo can be efficiently taken in and out of the cargo compartment. In particular, in the case of a deep cargo compartment, such a conveyor is extremely effective for loading and unloading operations.
The conveyor may be equipped with a partition having a surface orthogonal to the front-rear direction of the cargo compartment.

The prior art will be described with reference to FIGS. 13 and 14 and reference numerals shown therein. First, the partition b reciprocates in the cargo compartment in the front-rear direction with the movement of the conveyor c. Even when a small amount of cargo is stacked in the cargo compartment, the provision of the partition b can prevent inconvenience such that the stacked cargo collapses or falls during transportation. Further, the guide b can be moved while maintaining the vertical state by the guide rails r, r attached to the both side walls w, w of the cargo compartment and the roller member attached to the screen b [FIG. ),
(B)).

[0004]

As described above, the partition b has a structure in which a lower portion thereof is fixed to a constituent member of the conveyor c and moves with the rotation of the conveyor c. The partition b becomes unstable when it moves back and forth in the cargo compartment in the front-rear direction. For this purpose, guide rails r, r for supporting the upper part of the partition b are mounted on both side walls w, w in the width direction of the cargo compartment [FIG.
3 (A), (B)).

A lower portion of the partition b is fixed to a component of the conveyor c, and guide rollers provided on the partition b are supported by guide rails r, r, so that the partition moves while maintaining a vertical state. You can do it.

Incidentally, in the cargo compartment, both side walls w, w facing each other in the width direction of the cargo compartment may not always be exactly parallel due to a machining error or the like generated at the time of manufacturing at a factory. FIG. 14 (A)]. For this reason, the guide rails r, r attached to the both side walls w, w in the cargo compartment cannot similarly be accurately parallelized. For example, even if only one of the side walls w, w of the cargo compartment is manufactured in a state of being inclined at a slight angle θ from the design reference along the front-rear direction, the side walls are no longer parallel. [See FIGS. 14A and 14B].

For this reason, the opposing width of the two guide rails r, r is wide at one end of the cargo compartment, and the opposing width of the two guide rails r, r is narrow at the other end. Have a great adverse effect on In the worst case, the two roller members of the screen strongly contact the guide rails and cannot move (see FIG. 14B).

Alternatively, on the side where the opposing width of the two guide rails r, r is widened, the roller member may come off the guide rails r, r. Further, on the side where the opposing width of the guide rails r, r is narrow, the roller member strongly contacts the guide rails r, r, and the partition cannot move.

Further, in the worst case, even if the partition b is immovable, the conveyor continues to move even if the partition b is immovable. External forces can be applied, which can damage these devices.

[0010] Such a situation occurs because the guide rails r, r are mounted above the both side walls w, w of the cargo compartment. Therefore, in order to prevent such a situation, it is not possible to set a spacer or the like between the side wall w and the guide rail r so that the two guide rails r and r are parallel to each other. However, it is extremely difficult and cumbersome to accurately set the parallelism by such adjusting means.

[0011] Even if the opposite side walls of the cargo compartment are manufactured exactly in parallel, or if the guide rails are accurately mounted on both side walls of the cargo compartment, collisions or collisions may occur during long-term use. In some cases, the cargo may hit both side walls due to the impact of traveling or the collapse of the load inside. Therefore, both side walls are deformed and the guide rail is also deformed. As a result, even though the partition was moving smoothly in the initial stage, the motion may gradually deteriorate.

Further, as a second problem, a screen is provided to prevent the cargo in the cargo compartment from collapsing.
Frequently, cargo collapses when it is suddenly stopped during transportation, and in such a case, the cargo collides vigorously with the partition, and the partition receives a large shock received from the cargo, It often happens that it breaks down and collapses. For that purpose, the partition must be able to withstand the impact load of the collapsed cargo sufficiently.
However, due to the limitations of the cargo compartment, it was difficult to make a large space for reinforcing the partition.

[0013]

Means for Solving the Problems Therefore, the inventor of the present invention has intensively studied to solve the above-mentioned problems, and as a result, the present invention
A partition member is provided between the conveyor mounted on the floor of the cargo compartment of the truck and the two moving column members, and the lower ends of the two moving column members are connected to the conveyor via bases at the lower ends thereof.

According to the first aspect of the present invention, a cargo hold A of a truck is provided.
Of a conveyor C which is mounted on the floor part A _1, a shielding member 12 between the two moving column members 11 is provided, and a through a base 15, 15 at the lower end of the two moving column members 11 Connected to the conveyor C, together with the conveyor C
A partition B reciprocating in the front-rear direction of the partition B, and upper guide portions 13, 13 provided at positions above the moving column members 11, 11 of the partition B and having two guide rollers 13a, 13a rolling on a horizontal plane. And two guide rails 10, 10 installed in parallel with the cargo compartment ceiling 20 in the cargo compartment A, and the guide rollers 13a, 13a
By using a truck cargo room provided with a moving cargo handling device that rolls in the insides 0 and 10, the reciprocating movement of the partition B in the cargo room A in the front-rear direction can always be improved.

To describe the above effect in detail, it is often the case that the cargo compartment A is manufactured with a machining error at the time of manufacturing.
For this reason, the opposing cargo compartment side walls 21 and 21 may not be parallel. However, in the present invention, the two guide rails 10, 10 are attached to the cargo compartment ceiling 20 so as to be parallel to each other, so that, for example, the parallelism with both cargo compartment side walls 21, 21 is incorrect. Even so, it is not affected by such a condition at all. Therefore, the partition B can maintain good reciprocating movement of the cargo compartment A in the front-rear direction at all times.

Further, even if the cargo compartment side walls 21 and 21 of the cargo compartment A are distorted or deformed during a long-term use, the cargo compartment ceiling 20 is hardly affected by the cargo compartment A. Guide rail 1 mounted on ceiling 20
0 and 10 can also prevent the movement of the partition B from deteriorating over a long-term use.

Next, according to a second aspect of the present invention, in the first aspect, a reinforcing roller 1 is provided at an upper portion of the two movable column members 11.
A reinforcing part 14 having a reinforcing rail 14a is mounted to protrude to the rear side of the cargo compartment A, and the reinforcing roller 14a is
By providing a truck cargo room provided with a mobile cargo handling device that rolls inside, the partition B can sufficiently withstand the impact of the cargo in the cargo room A against collapse of the load.

To describe the above effect in detail, when the cargo collapsed on the partition B collides vigorously, the load F from the cargo due to the collision tries to defeat the partition B. However, partition B
Is equipped with a reinforcing portion 14, and the reinforcing portion 14
Is mounted so as to protrude to the rear side of the cargo compartment A when viewed from the partition B.

Therefore, a reaction force R from the guide rail 10 side is applied to the reinforcing roller 14a at the tip of the reinforcing portion 14 so as to resist the partition B which is about to fall down.
It acts as an action opposing the falling direction of the partition B, prevents the partition B from falling, and provides sufficient durability and strength.

Next, a third aspect of the present invention is directed to the first or second aspect.

Occasionally, the traveling rollers 15b, 15b of the base 15 provided at the lower ends of the movable pillar members 11, 11 are connected to the floor A _1.
The movement of the partition B by the conveyor C can be smoothed, and the operation can be quiet.
