It is in a state of extending downward in the vertical direction Y. Further, the plate 31 is located behind the rear end edge (tip edge) 90a of the tailgate 90 in the front-rear direction X.
That is, the plate 31 intersects (crosses up and down) the load receiving surface 91 on the rear side of the rear end edge 90a of the tailgate 90, and when the rear part of the vehicle is visually recognized from the rear of the vehicle, the plate 31 is the tailgate 90. It functions as a member that covers the trailing edge 90a (see FIG. 7).

When the stopper device 10 is in the carry-in / out position (see FIGS. 10 and 11), the plate 31 is in the carry-in / out position (down position) and covers the rear end edge 90a of the tailgate 90 from above (of the tailgate 90). It is a state in which the trailing edge 90a straddles the front-rear direction X), and is hung between the ground surface G and the load receiving surface 91 of the tailgate 90.
At this time, the plate 31 functions as a slope plate that contributes to improving the workability of loading and unloading the load B between the ground surface G and the load receiving surface 91.

Next, each component of the stopper device 10 will be described.

The fixing plate 11 is attached to the rear end of the tailgate 90 as shown in FIG.

In addition, the rotation is restricted by the chain 50 and it is located in the upright position.
When the tailgate 90 is in the open position and the plate 31 is in the upright position (see FIG. 6), the upper portion 41 of the plate is in a state of protruding above the load receiving surface 91 of the tailgate 90, and is a stopper (load stop) for the luggage B. Functions as. The lower plate 42 is in a state of extending downward from the load receiving surface 91 of the tailgate 90. That is, the plate 31 is located at the carry-in / out position (down position) when the tailgate 90 is at the ground clearance position (carry-in / out height position), and may be positioned by rotating to the upright position. Can not.
Although various states can be taken as the orientation of the plate 31 in the upright position (inclination angle α2 with respect to the load receiving surface 91), the load receiving surface 91 (base end side surface 91b of the load receiving surface) and the plate of the tailgate 90 in the open position It is more preferable that the angle α2 formed with the upper portion 41 (plate body 31 m) is an acute angle (see FIG. 6).
When the tailgate 90 is in the open position and the plate 31 is in the upright position, the colored display part on the front side surface 31s of the plate 31 and the character display part such as "working" are easily visible from the rear of the vehicle, and cargo handling work is in progress. It functions as a warning sign to that effect.
Further, when the tailgate 90 is in the open position and the plate 31 is in the upright position, at least a part of the tailgate 90 is located behind the trailing edge (tip edge) 90a of the tailgate 90, that is, outside the tailgate 90. Further, the plate 31 is in contact with the trailing edge 90a of the tailgate 90. That is, when the plate 31 is in the upright position, the trailing edge 90a of the tailgate 90 is covered by the plate 31 from the rear side in the front-rear direction X. That is, the plate 31 functions as a member that shields the rear end edge 90a of the tailgate 90 from the rear side of the vehicle when in the upright position.

The carry-in / out position (down position) is the position of the plate 31 when the stopper device 10 is in the carry-in / out position.
When the tailgate 90 of the plate 31 descends from the loading platform height position (see FIG. 3) to the ground clearance position, the contact member 60 comes into contact with the ground surface G during the movement. During the descending operation after the contact member 60 comes into contact with the ground clearance G, the plate 31 rotates from the upright position to the carry-in / out position in the prone direction R4 (see FIGS. 6 and 10) described later, and the tailgate 90 When it reaches the ground clearance position, it is located in the carry-in / out position (down position).
When the tailgate 90 is at the ground clearance and the plate 31 is at the loading / unloading position (see FIG. 10), the upper plate 41 is along the load receiving surface 91, and the lower plate 42 is along the ground surface G. is there. That is, the plate 31 is in a state of covering the trailing end edge 90a of the tailgate 90 from the upper side, and is in a state of a gentle ascending slope from the ground surface G side toward the load receiving surface 91 side, and the load receiving surface 91 and the ground surface G It functions as a slope plate hung between and.

The storage position is the position of the plate when the stopper device is in the storage position.
When the plate 31 is rotated in the storage direction (in the same embodiment, the same direction as the prone direction R4) from the upright position to the storage position while the rotating plate 12 is located at the storage position, the plate 31 is moved to the storage position. When it reaches, it comes into contact with a locking member (not shown) and is located at the storage position shown in FIG.
The plate 31 in the storage position is such that when the stopper device 10 is in the storage position (that is, the rotating plate 12 is in the storage position) (see FIG. 5), the lower portion 42 of the plate is the tailgate 90 rather than the second shaft body 22. It will be in the state of being located 90b on the base end side of. Further, at this time, in the present embodiment, the upper end edge 31a of the plate is in contact with the load receiving surface 91.
In this state, when the tailgate 90 is moved to the closed position and the luggage compartment 80 is closed (see FIGS. 1 and 2), the tip side of the rotating plate 12 extends downward in the vertical direction Y, and the plate In 31, the extended portion 31e (in other words, the lower portion 42 of the plate) extends downward in the vertical direction Y.
As will be described later, the position C of the center of gravity of the plate member 30 is below (the other side) of the plate 31 in the vertical direction H from the position of the second shaft body 22.
Therefore, when the plate member 30 is in the stowed position, the center of gravity of the plate member 30 is located below the second shaft body 22 in the vertical direction Y, and the plate member 30 is excellent in stability as a stowed state. There is.

As shown in FIGS. 6 and 11, the contact member 60 is installed on the lower end edge (lower end edge 31b of the plate 31) of the pair of extension portions 31e formed on both sides of the plate 31 in the vehicle width direction W. There is. That is, the contact member 60 is composed of a pair of contact members 60, 60 attached to both side ends of the plate 31 in the vehicle width direction W.
The contact member 60 includes a contactor 61 that comes into contact with the ground surface G and a shaft member 62 that supports the contactor 61.
The shaft member 62 is a rod-shaped member installed on the lower end edge of the extension portion 31e so as to extend in the vehicle width direction W.
The contactor 61 is attached to the shaft member 62 in a state of being rotatable around a rotation axis in the vehicle width direction W. In the present embodiment, the contactor 61 is formed of a cylindrical roller, and is attached to an end portion of a rod-shaped shaft member 62 on the outer side in the vehicle width direction.
Further, the contactor 61 is provided with a contact surface 61a that can move along the ground surface G in a state of being in contact with the ground surface G on the outer circumference thereof (the cylindrical outer circumference of the cylindrical roller).
The contactor 61 is rollable, and the contact surface 61a of the contactor 61 is a smooth surface.
Therefore, in the lowering operation of the tailgate 90, which will be described later, the contactor 61, which comes into contact with the ground surface G in the middle of the operation, can smoothly move (roll) along the ground surface G. ..
As the configuration for realizing smooth movement of the contactor 61 with the ground surface G, various configurations such as rolling and sliding can be mentioned.
That is, the contact surface (outer peripheral surface of the cylindrical roller) of the contact member 60 with the ground surface G of the contact member 60 has a rolling kinematic pair (rotating kinematic pair) configuration that rolls with respect to the ground surface G. The configuration is not limited to this, and a sliding kinematic pair configuration may be used as long as it can smoothly move along the ground surface G in contact with the ground surface G.
The contactor 61 used in the present embodiment has a rough road surface or the like, and can be said to be preferable as a contactor for the stopper device 10.
Since a well-known configuration can be used as the mounting structure of the contactor 61, the illustration and description are omitted here.

When the tailgate 90 descends from the loading platform height position to the ground clearance position, the contactor 61 of the contact member 60 comes into contact with the ground clearance G in the middle of its operation.
During the subsequent lowering operation of the tailgate 90, the contactor 61 is maintained in contact with the ground surface G.
As the tailgate 60 descends, the plate 31 rotates in the prone direction R4 relative to the tailgate 90, and rotates from the upright position to the loading / unloading position (prone position) (see FIG. 10). ..
As the plate 31 rotates in the prone direction R4, the contactor 61 in contact with the ground surface G gradually rolls and moves backward in the front-rear direction X along the ground surface G.
By the way, the ground surface G at the loading / unloading site of the luggage B may be a rough surface such as an asphalt road surface or an unpaved road surface.
In this regard, if the contactor 61 of the contact member 60 that first contacts the ground surface G among the members that are moving downward during the descending operation of the tailgate 90 is rotatable, the ground surface G is on a rough surface. Even if there is, it can move smoothly along the ground surface G at the same time as it comes into contact with the ground surface G, preventing the plate 31 from getting caught in the rough ground surface G, and the plate member 30 is used during use. It rotates smoothly in the prone direction R4 toward the position.

The position C of the center of gravity of the plate 31 (see FIGS. 6 and 10) is below the position of the second shaft body 22 in the vertical direction H of the plate 31.
Therefore, with the tailgate 90 in the loading platform height position (open position) (see FIG. 3), the plate 31 is rotated in the upright direction R3 to position the plate 31 in the upright position as shown in FIG. (Move the stopper device 10 to the load stop position) and when the plate (load stop plate) 31 is in the upright position, the center of gravity C of the plate 31 is in the connection position with the rotating plate 12 (the tip portion 12a of the rotating plate 12). It is located below the vertical direction. At this time, the center of gravity position C is located below the tip edge 90a of the tailgate 90 in the vertical direction.
Therefore, when the plate 31 is rotated in the standing direction R3 and reaches the standing position, it autonomously rotates in the standing direction R3 by the action of gravity based on its own weight, and is positioned at the standing position by the rotation regulation by the chain 50. Will be done.
The plate member 30 includes a contact member 60 installed on an extension portion 31e extending downward thereof and a lower end edge (other end edge) 31b thereof, and by providing these configurations, the center of gravity is more reliably and clearly defined. The position C is arranged below the plate with respect to the second shaft body 22.
If the center of gravity position C is below the plate of the second shaft body 22, the stopper device 10 is stored in a stable state when the stopper device 10 is moved to the storage position and the tailgate 90 is closed (FIGS. 1 and 1). (See FIG. 2), when the plate member 31 is positioned in the upright position with the stopper device 10 in the loading position, the plate member 31 is reliably positioned in the upright position in cooperation with the chain 50. With the plate member 31 of the present embodiment, these effects can be obtained more reliably.
The position C of the center of gravity shown in FIGS. 5 and 10 is a position shown for convenience of explanation.

The chain (fastening member) 50 is a member that fastens the fixing plate 11 and the plate 31. More specifically, one end of the chain 50 is fixed to the upper side surface of the fixing plate 11, and its multi-end is fixed to the back side surface of the plate 31 (the surface opposite to the front side surface 31s).
The upper side surface of the fixing plate 11 is, for example, a surface that faces upward when the tailgate 90 is in the open position.
More specifically, the chain 50 is a member that regulates the rotation range of the plate 31 that rotates in the standing direction R3 from the loading / unloading position side (down position side) toward the standing direction side, and is a member of the standing direction R3. The rotation range is regulated by the chain 50 up to the upright position.
In the description of the present embodiment, the rotation direction opposite to the standing direction R3 is referred to as a prone direction R4 (see FIG. 6).
Regarding the rotation range of the plate 31 on the R4 side in the prone direction, it is sufficient that the plate can rotate to the loading / unloading position. Therefore, the rotation range of the prone direction R4 may be restricted by the carry-in / out position, or may be rotatable from the carry-in / out position to a predetermined position further rotated in the prone direction R4.

As described above, the plate member 30 can be retrofitted to the tailgate 90 and can be easily removed after mounting, so that the plate member 30 is excellent in maintainability.
That is, the stopper device 10 according to the present invention can also be installed in a tailgate provided with a conventional stopper.

Next, a method of using the tailgate 90 of the vehicle equipped with the stopper device 10 of the present embodiment will be described.

Here, the work of carrying out the luggage B from the luggage compartment 80 with the tailgate 90 closed (see FIG. 1) as a starting point will be described as an example.
The operation of the opening / closing elevating device 99 that rotates the tailgate 90 will not be described.

First, the operator activates the opening / closing elevating device 99 to rotate the tailgate 90 in the closed position shown in FIG. 1 to the open position shown in FIG.
As a result, the load receiving surface 91 of the tailgate 90 is substantially parallel to the ground surface (loading / unloading height surface) G, and is positioned flush with the floor surface of the loading platform 81.
When the rotation of the tailgate 90 to the open position (loading platform height position) is completed, the stopper device 10 is in the storage position (see FIG. 3).

Next, the operator grips, for example, the rotating plate 12 and the plate member 30 of the stopper device 10, rotates the rotating plate 12 in the usage direction R2 (see FIG. 5), and rotates the plate member 30 in the upright direction R3. Rotate to (see FIG. 6) to position the stopper device 10 in the loading position (see FIG. 6).

When the stopper device 10 is positioned at the load-holding position, the plate (load-stopping plate) 31 is positioned at the upright position as shown in FIG.
The plate 31 in the upright position moves such luggage B when luggage B on the tailgate 90 attempts to move rearward (that is, outside the tailgate 90) through the trailing edge (tip edge) 90a. Functions as a stopper to stop.
For example, when the luggage B of the loading platform 81 is placed on the trolley D (see FIG. 6), one of the luggage B approaches the tailgate 90 during the work of moving one or more luggage onto the tailgate 90. It may move, but if the stopper device 10 is in the load-holding position and the plate 31 is in the upright position, the load B will move outward beyond the trailing edge 90a of the tailgate 90. Is prevented.

By the way, the plate 31 is arranged outside the trailing edge 90a of the tailgate 90 when in the upright position. Therefore, the entire load receiving surface 91 of the tailgate 90 can be used as an area on which the load B is placed.
Further, the load receiving surface 91 of the tailgate 90 is also a work area for the cargo handling operator, but as in the stopper device 10 of the present embodiment, the plate 31 (see FIG. 6) located in the upright position is outside the load receiving surface 91. If it is installed so as to be located, for example, an operator during cargo handling work can more reliably prevent the plate 31 from being unknowingly stepped on. If the cargo handling operator is prevented from stepping on the plate 31, the standing position of the plate 31 is more reliably secured, and the luggage B is more reliably prevented from falling from the tailgate.

Focusing on the fact that the tailgate 90 is positioned at the ground clearance position (loading / unloading height position) and the load is loaded / unloaded from the ground surface G (see FIG. 9), the trailing edge of the tailgate 90 90a is a part located on the flow line of the cargo to be carried in and out. That is, since the luggage B is moved so as to cross the rear end edge 90a at the time of loading and unloading, the rear end edge 90a has a relatively thin structure. It is considered that the thinner the thickness, the smaller the step between the ground surface and G and the load receiving surface 91 of the tailgate 90, which makes it easier to carry in and out the load. However, if the trailing edge 90a of the tailgate 90 is thinned, it tends to be difficult to see.
In particular, since the tailgate 90 in the open position (see FIG. 6) is almost horizontal, the height position of the line of sight of the operator or a third party is one with the height position of the tailgate 90 (rear end edge 90a). In this state, when the direction of the tailgate 90 (especially the trailing edge 90a of the tailgate 90) is visually recognized, it is difficult to visually recognize the presence of the tailgate 90, and a sense of distance from the tailgate 90 (especially). Perspective) may be difficult to grasp.
In this respect, the stopper device 10 of the present embodiment includes a plate member 30 having a plate 31 that is in an upright state when the load is stopped, and the plate 31 in the upright position is conspicuous and extremely visible. Are better. Even if the height position of the line of sight is the height position of the trailing edge 90a of the tailgate 90, the plate member 30 can be reliably visually recognized.
If the plate member 30 can be easily visually recognized, it is possible to visually recognize that the vehicle is in the process of cargo handling at a place relatively distant from the vehicle in the process of cargo handling, and pedestrians approaching the vehicle inadvertently or Third parties such as bicycle and motorcycle drivers can be reduced to a minimum. If the number of people who approach carelessly can be reduced, the workability of cargo handling work can be improved.
Further, since the plate member 30 is also a member that covers the rear end edge 90a of the tailgate 90 from the rear, direct contact between the rear end edge 90a of the tailgate 90 and an object such as luggage is prevented, and the rear end edge 90a of the tailgate 90 is prevented. The impact applied to contact objects such as luggage from the edge 90a is reduced.

When the work of carrying out the luggage B in the luggage compartment 80 onto the tailgate 90 is completed, the tailgate 90 at the loading platform height position (open position) is then lowered to the ground clearance position, and finally above the ground. It is lowered to the height position (see FIG. 9).
By the way, when the tailgate 90 is lowered toward the ground clearance position, the contactor 61 of the contact member 60 of the plate member 30 of the stopper device 10 first comes into contact with the ground clearance G in the middle of the operation.
The ground surface G is often a rough surface such as a weathered asphalt road surface, but like the stopper device 10 of the present embodiment, a contactor 61 whose first contact portion with the ground surface G is rollable and easy to move is used. With the contact member 60 having the contact member 60, even if the ground surface G is a rough surface, it is possible to prevent the lower end portion 31b of the plate 31 from being caught on the ground surface G.
Therefore, the operation of lowering the tailgate 90 toward the ground clearance position can be smoothly performed.
Further, the plate 31 of the plate member 30 that rotates to the carry-in / out position (down position) as the tailgate 90 descends is smoothly rotated. Further, since the chain 50 is used as a member for positioning the plate 31 of the plate member 30 in the upright position, when the plate 31 rotates in the prone direction R4 in conjunction with the lowering operation of the tailgate, the movement is moved. Not disturbed.
That is, the tailgate 90 at the height of the loading platform can be smoothly moved to the height above the ground, and the plate member 30 at the upright position can be smoothly moved to the loading / unloading position.

When the tailgate 90 is moved to the ground clearance position, the luggage B on the tailgate is then carried out to the ground clearance G.

By the way, as described above, in the tailgate 90 provided with the stopper device 10 of the present embodiment, when the tailgate 90 is moved to the ground clearance position, the contactor 61 comes into contact with the ground surface G during the operation. The plate 31 of the plate member 30 autonomously rotates to the loading / unloading position (prone position) shown in FIG. 10 by the force (force opposite to gravity) received by the contactor 61 from the ground clearance G. In other words, the plate 31 rotates in the prone direction R4 toward the carry-in / out position in conjunction with the lowering operation of the tailgate 90.
Therefore, when the descent of the tailgate 90 to the ground clearance position is completed, the work of carrying out the luggage B to the ground clearance G can be started immediately.

When loading and unloading the luggage B between the tailgate 90 and the ground surface G, the luggage B passes through the trailing edge (tip edge) 90a of the tailgate. More specifically, the luggage B passes over the trailing edge (tip edge) 90a of the tailgate.
In addition, the luggage passes over the plate 31 located in the prone position (carry-in / out position). In the case of the luggage B shown in the present embodiment, the luggage B passes while rolling and moving on the plate 31.
In this regard, the plate 31 of the stopper device 10 of the present embodiment is a thin plate-shaped steel member, and is a long plate-shaped member extending in the vehicle width direction W, and has flexibility. is there.
Therefore, when the luggage B passes over the plate 31, the plate 31 bends according to the weight of the luggage B. Immediately after the movement of the tailgate 90 to the ground clearance is completed, it is assumed that there are some steps between the load receiving surface 91 and the plate 31 of the tailgate 90 and between the plate 31 and the ground clearance G. However, the plate 31 is bent by the weight of the luggage B passing over the plate 31 in the loading / unloading work, and the luggage B can be moved smoothly.

The loading work of carrying the luggage B on the ground into the load receiving surface 91 of the tailgate 90 and further carrying the luggage B on the tailgate into the luggage compartment 80 of the vehicle is a work in which the above-mentioned carrying-out work is performed in the reverse direction. Therefore, a detailed description of the loading operation will be omitted here.

When the loading of the load B into the luggage compartment 80 is completed, the stopper device 10 (see FIG. 6) in the load stop position is moved to the storage position (see FIG. 5).
As a result, the entire stopper device 10 is located inside the load receiving surface 91 of the tailgate 90, and when the tailgate 90 is rotated to the closed position, the entire stopper device 10 becomes the luggage compartment 80. It is stored.

The above-mentioned unloading work is a description of the work of unloading the luggage B of the luggage compartment 80 to the ground surface G.
By the way, the tailgate 90 can be a carry-out destination (carry-in / out destination) of the luggage B on the tailgate 90 as long as the surface can be brought into contact with the tip edge 90a.
For this reason, at a cargo handling work site such as a distribution warehouse, luggage may be carried out on a platform (carry-in / out height position) that is one step higher than the ground.
In this case, the height of the descending destination in the descending operation of the tailgate 90, that is, the height of the platform floor surface (loading / unloading height surface) (loading / unloading height position) is not the height of the ground on which the vehicle travels. , The height of the platform is one step higher than the ground.
Then, in this case, only a part of the tailgate 90 (for example, the rear end including the trailing edge 90a) is brought into contact with the platform, and most of the tailgate 90 floats in the air outside the platform. Become in a state.
Even when loading and unloading the luggage B on such a platform, the contact member 60 of the stopper device 10 located at the loading / unloading position is arranged behind the tailgate 90 at the open position in the vehicle front-rear direction. The plate member 30 operates smoothly as in the case where the tailgate 90 is lowered to the ground surface G.
