The loading platform exhibits an operating posture that occupies the ground in a state of protruding behind the loading platform when loading and unloading the cargo, and exhibits a retracting posture that does not occupy the ground behind the loading platform when the cargo is not loaded and unloaded.
That is, when the loading platform changes its posture from the retracted posture to the operating posture, the loading platform moves to the space behind the loading platform. Therefore, when the loading platform is in the retracted position, the space behind the loading platform is vacant, and people can come and go and things can be placed.
However, if the loading platform is changed to an operating posture that projects to the rear of the loading platform in such a state, the loading platform may come into contact with people or objects.
Therefore, according to this aspect, since the light beam irradiating device for irradiating the light beam indicating the area of the ground occupied by the consignment pedestal behind the vehicle, the light irradiating device is placed in the area occupied by the consignment pedestal in the operating posture on the ground. By irradiating the light beam, the person on the rear side of the vehicle can see the ground irradiated with the light beam and recognize in advance that the cradle is moving. Therefore, before the consignment stand is deployed in the operating posture, the surrounding people are alerted and can evacuate from the vicinity of the area. In addition, the operator who loads and unloads the cargo can confirm whether or not an object exists in the area irradiated with the light beam before the cargo receiving table is in the horizontal operating posture.
If an object exists in the area irradiated with the light beam, the object (obstacle) is exposed to the light beam, so that the worker notices the existence of the object and removes (moves) the object. Can be done. If an object exposed to light cannot be removed, the worker can take safety measures such as moving the vehicle and changing the location where the cargo loading and unloading work is carried out. By irradiating the light beam with the light beam irradiating device, the operator can make such a judgment, and the situation where the consignment stand comes into contact with a person or an object can be avoided, which is extremely safe.

Hereinafter, description will be given with reference to the drawings.
As shown in FIGS. 1A, 1B, and 2B, the vehicle 1 has a packing box 2 mounted on a vehicle body 1a (loading platform). A bumper device 3 and a load receiving platform elevating device 4 are attached to the rear portion of the vehicle body 1a. The load receiving platform elevating device 4 has a parallel link mechanism 4a. The base side (front end side) of the cargo cradle elevating device 4 is attached to the vehicle body 1a, and the cargo cradle 7 on which luggage can be placed is attached to the front end side (rear end side) which is a free end.

The parallel link mechanism 4a includes a drive cylinder 5, and the height position of the load receiving table 7 is set between the height of the ground G and the floor surface (not shown) of the load box 2 according to the expansion and contraction of the drive cylinder 5. You can change it with. Further, a drive cylinder (not shown) is provided at a portion of the parallel link mechanism 4a to which the load receiving table 7 is connected. By driving the drive cylinder (not shown), the posture of the load receiving table 7 can be switched between the upright state (retracted posture) and the horizontal state (operating posture).

Here, the operating posture refers to a state in which the load receiving table 7 is in a horizontal state and is arranged between the floor surface height of the packing box 2 and the ground G. Further, the retracted posture refers to a state in which the load receiving table 7 has moved from between the floor height of the packing box 2 and the ground G.
The load receiving platform elevating device 4 having the parallel link mechanism 4a is well known in the past, and other detailed description thereof will be omitted.

A light irradiation device 8 (safety device) is provided on the upper part (kamoi portion) of the packing box 2. The light irradiation device 8 is composed of an LED lamp, and for example, an "LED drawing lamp" manufactured by Koito Manufacturing Co., Ltd. can be adopted.

As shown in FIGS. 1A and 1B, the light irradiation device 8 irradiates the irradiation light 9. The irradiation light 9 is irradiated from the light irradiation device 8 to a predetermined range. As shown in FIG. 1 (b), the range of the irradiation light 9 is the same as or slightly larger (wider) than the area occupied by the cradle 7 in the operating posture.

That is, the light beam irradiating device 8 can irradiate a region having the same size as the region occupied by the consignment 7 arranged on the ground G, or a region slightly wider than the region occupied by the consignment 7. .. In other words, as shown in FIG. 2, the irradiation light 9 irradiated from the light irradiation device 8 spreads over the light irradiation area 10 of the ground G, and the area of the light irradiation area 10 is such that the cradle 7 in the horizontal posture is on the ground. Same as or slightly larger than the area occupied on G.

In the present embodiment, as a preferred embodiment, an example is shown in which the light irradiation area 10 is the same as or slightly larger than the area occupied by the consignment 7 on the ground G, but the light irradiation area 10 is the consignment 7. It may be smaller than the area occupied by.

When the light irradiation area 10 coincides with the area occupied by the consignment 7 on the ground G, the contour of the light irradiation area 10 indicates the boundary between the area occupied by the consignment 7 on the ground G and other areas. .. That is, as long as it is outside the light irradiation region 10 in this case, even if the load receiving table 7 in the standby posture changes its posture to the operating posture, it does not come into contact with the load receiving table 7.

Further, "slightly" means about plus or minus 30% or less of the area occupied by the consignment 7 on the ground G. Actually, rather than matching the area occupied by the consignment 7 on the ground G with the area irradiated by the irradiation light 9, or making the area irradiated by the irradiation light 9 slightly narrower, the irradiation light 9 It is preferable for safety that the irradiated area is slightly wider.

The light ray irradiating device 8 can irradiate a light ray having directivity, and draws a character in the light ray irradiation range 10a as shown in FIG. 3A, or draws a character as shown in FIG. 3B. Irradiate the ground G arbitrarily, such as irradiating the irradiation range 10b with light rays in a frame shape and drawing a frame in the light beam irradiation range 10b, or irradiating the entire area of the light beam irradiation range 10c with light rays as shown in FIG. 3C. Characters and shapes can be drawn. Further, in FIGS. 3 (a) to 3 (c), the light ray irradiating device 8 may irradiate a blinking light ray and indicate a character or a shape drawn on the ground G by the blinking light ray.

In the present embodiment, the light beam irradiating device 8 starts irradiating light rays at the same time when the power of the load receiving platform elevating device 4 is turned on. That is, the light irradiation device 8 starts irradiating the irradiation light beam before the load receiving table 7 in the retracted posture changes (deploys) the posture to the operating posture in the horizontal state. Then, when the consignment pedestal 7 exhibits an operating posture, the light irradiation device 8 stops the irradiation of the irradiation light. As described above, the timing of starting and stopping the irradiation of the irradiation light 9 of the light irradiation device 8 is configured to be linked with the operation of the load receiving platform elevating device 4. According to the irradiation instruction, it is possible to irradiate the ground (light ray irradiation area 10) in the area occupied by the loading platform 7 in the operating posture with the irradiation light beam.

Here, the irradiation of the irradiation light 9 of the light irradiation device 8 and the stop of the irradiation may be performed manually by providing a dedicated switch regardless of the operation of the loading platform elevating device 4.
Further, the light irradiation device 8 may constantly irradiate the irradiation light 9.

In the present embodiment, an example in which the light beam irradiating device 8 irradiates the irradiation light beam 9 according to the area (area) occupying the ground G when the consignment table 7 is arranged on the ground G has been described. Reference numeral 9 is the widest range of the maximum area of the trajectory drawn by the cradle 7 when the cradle 7 changes its posture from the retracted posture to the operating posture (the widest projected onto the ground G of the cradle 7 when the cradle 7 moves up and down. Area).

That is, as shown in FIGS. 4 (a) to 4 (c), the load receiving table 7 rotates around a connecting member 6 (a portion fixed to the vehicle body 1a (loading platform) side) integrated with the vehicle body 1a. , Move from the floor height of the packing box 2 (FIG. 4 (a)) to the ground G (FIG. 4 (c)). At that time, when the load receiving table 7 comes to the height position (predetermined height position) of the rotation center of the parallel link mechanism 4a (FIG. 4B), the end side 7a of the load receiving table 7 is from the vehicle body 1a. Most prominent. That is, there is almost no difference in the positions in the front-rear direction (parts A and C projected on the ground G) of the end side 7a of the load receiving table 7 at the height positions shown in FIGS. 4 (a) and 4 (c). However, as shown in FIG. 4B, when the load receiving table 7 reaches the height position of the rotation center of the parallel link mechanism 4a, the end side 7a is a position where the portion B is projected beyond the position where the portion A is projected. Protrudes backwards.

Therefore, if a person or an object approaches the vehicle body 1a from the B portion of the ground G, the cradle 7 comes into contact with or collides with the person or object when the cradle 7 reaches the height position of the connecting member 6. It ends up.
Therefore, the irradiation range of the light beam irradiating device 8 is expanded to at least the B portion of the ground G (the movement locus of the loading platform 7 and the maximum protruding range of the receiving platform 7 to the rear of the vehicle 1).
That is, the irradiation light 9 is irradiated to the area OB projected in plan view onto the ground G of the loading platform 7 in the operating posture at the height position of the rotation center (connecting member 6) of the parallel link mechanism 4a. Here, the O portion is a portion near the rear portion of the vehicle body 1a, is a front end portion of the projection region of the load receiving table 7, and indicates the position of the irradiation light beam emitted by the light beam irradiating device 8 on the most side of the vehicle body 1a.

As a result, it is possible to prevent a person or an object from entering the range of the movement locus drawn by the load receiving table 7 when ascending or descending, and it is possible to avoid a situation in which the person or an object comes into contact with or collides with the load receiving table 7. That is, it is preferable that the light irradiation device 8 irradiates not only the OA region in the front-rear direction of the vehicle 1 but also the OB region with the irradiation light 9.

The magnitude relationship between the area OA and the area OC changes depending on the floor height of the consignment 7 and the height of the connecting member 6, but the area OB is always larger than the area OA and the area OC. That is, if the region OB is irradiated with the irradiation light 9 and no person or object enters the region OB, the cradle 7 that moves up and down does not come into contact with or collide with anything.

In the present embodiment, the light irradiation device 8 is provided in the lintel portion (upper part) of the packing box 2, but the installation position of the light irradiating device 8 may be other than the lintel portion of the packing box 2. There is no. For example, the light irradiation device 8 may be provided on the threshold portion (lower part) of the packing box 2, the bumper device 3, the license plate (not shown), and the vehicle body 1a (chassis frame).

Further, in the present embodiment, an example in which one light irradiation device 8 is provided is shown, but a plurality of light irradiation devices 8 may be provided. For example, it may be provided in some (multiple locations) of the lintel portion and the threshold portion of the packing box 2, the bumper device 3, the license plate (not shown), the vehicle body 1a (chassis frame), and the like.

The color of the irradiation light 9 is arbitrary and may be any color. When a plurality of light beam irradiation devices 8 are provided, the color types of the irradiation light rays may be aligned to a single color, or different colors may be used for each.

In the present embodiment, the case where the load receiving table 7 moves up and down by the parallel link mechanism 4a and switches between the horizontal posture and the standing position has been described. However, the load receiving table 7 is a vertical lifting type and an underfloor retractable type. However, the present invention can be implemented in the same manner. The vertical elevating type is a type in which the load receiving table 7 moves up and down along a support column provided on the vehicle (vehicle body 1a or packing box 2). The vertical posture of the load receiving table 7 to the horizontal posture (or vice versa) may be manually performed. The underfloor retractable type is a type in which the loading platform is stored (retracted) below the vehicle body 1a (loading platform) and protrudes rearward during operation.
