DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a rear gate structure with a rear gate chain in a vehicle carrier.

[Prior Art] Conventionally, in a loading platform such as a truck, in order to facilitate loading and unloading of luggage, a rear gate that is opened by pivoting a lower edge of the loading platform and falling backward is provided at the rear of the loading platform. It is provided.

Further, such a rear gate is provided with handle members projecting laterally on both sides, and the rear gate can be held in an upright closed state by engaging the handle members with the handle hooks on the side wall of the luggage carrier. It is like this.

In addition, chain hooks are provided on both sides of the rear gate, and the rear gate can be placed in a horizontal position by hooking the free end of the rear gate chain where the base end is attached to the fixed part of the luggage carrier part on this chain hook. It can be locked in the required posture, such as open or half-open in a tilted state.

[Problems to be Solved by the Invention] By the way, in the conventional chain hook mechanism as described above, since the proper position of the free end portion of the rear gate chain is simply hooked on the chain hook, the rear gate chain is used to form the rear gate. It is preferable to take measures to prevent the rear gate chain from being inadvertently disengaged from the chain hook while being held in the posture.

The present invention has been made in view of the above problems, and prevents the rear gate chain from being accidentally disengaged from the chain hook when the rear gate is held in a desired posture by using the rear gate chain. An object of the present invention is to provide a rear gate structure with a rear gate chain in a luggage carrier.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a rear gate structure with a rear gate chain in a vehicle carrier of the present invention is a vehicle carrier structure in which a lower edge portion is pivotally attached to a rear part of a vehicle carrier to the rear. It has a rear gate that opens when it falls down,
A rear gate chain for holding the rear gate in a desired posture in the opened state of the rear gate is interposed between the rear gate and the cargo bed portion, and the rear gate is attached to the rear gate so as to maintain the closed state in which the rear gate is erected. A handle member is provided that can engage with the handle hook on the side of the cargo bed by projecting and moving to the side, and the rear gate chain can be attached to and detached from the rear gate chain so that the rear gate chain can be attached to and detached from the rear gate. A chain hook which can be engaged is provided, and a shaft portion of the handle member is fitted into the inside of the chain hook, and the handle is engaged with the handle hook that is laterally projected and moved. The gap between the shaft of the member and the chain hook is made large enough to allow the rear gate chain to come out,
In order to make the gap between the shaft portion of the handle member and the chain hook small so that the rear gate chain does not come out in the disengaged state with the handle hook that is moved backward, It is characterized in that the shaft portion is configured to have large and small diameter shaft portions.

[Operation] In the above-described rear gate structure with the rear gate chain in the vehicle carrier of the present invention, the shaft portion of the handle member with the rear gate is formed with the large and small diameter shaft portions so that the shaft portion of the handle member corresponds to the chain hook. When the handle member is moved outwardly so that it can be engaged with the handle hook, the small diameter shaft portion opposes the chain hook, and the shaft portion of the handle member and the chain Widen the gap with the hook to allow the rear gate chain to come in and out.

Further, when the handle member is disengaged from the handle hook and is moving inward, the small-diameter shaft portion and the chain hook are displaced from each other, and the gap between the handle member shaft portion and the chain hook is narrowed. It is impossible to get in and out of the room. Therefore, in the rear gate open state in which the handle member is located inward, the rear gate chain hung on the chain hook will not come off.

[Embodiment] Referring to the drawings, a rear gate structure with a rear gate chain in a vehicle carrier according to an embodiment of the present invention will be described below. FIG. 1 is a perspective view showing a state in which a handle member is in an inward position, and FIG. Is a perspective view showing a state where the handle member is engaged with the handle hook and is in the outer position,
3 is a side view of the chain hook engaging portion taken along the line III-III of FIG. 1, FIG. 4 is a side view of the chain hook engaging portion taken along the line IV-IV of FIG. 2, and FIG. The figure is V- in Figure 2.
FIG. 5 is a cross-sectional view of the upper edge portion of the rear gate corresponding to the direction of the arrow V, and in each drawing, the same reference numerals indicate substantially similar parts.

By the way, Figs. 1 and 2 show one corner of the rear end of the lid-shaped luggage carrier of a vehicle such as a truck. In the drawings, 1 is a lower edge portion pivotally attached to a rear portion of the luggage carrier to the rear. In the rear gate which is designed to be tilted, the pair of handle members 2 is symmetrically provided at the upper edge portion (or near the upper edge portion) of the rear gate 1.
However, the shaft portion is penetrated by the handle member support metal fitting 3 (see FIG. 5) so that it can be rotated and slid inward and outward, and is provided in the horizontal direction.

The handle member 2 is mounted so as to be always pulled inward via a return spring (coil spring) 4 and a washer 5 between its inner end and the handle member support fitting 3. At the outer end of the handle member 2, a handle portion 2a bent in an L shape is formed.

Therefore, when the rear gate 1 is erected and the handle portion 2a is pulled outward (in the direction of the arrow b) and is rotated in the direction of the arrow a, the handle portion 2a is hooked on the handle hook 7 on the side wall 6 of the bed as shown in FIG. The handle member 2 is engaged with the handle hook 7 so that the rear gate 1 is locked in the closed state.

Further, a cutout window 3a extending from the side to the top is provided on the surface of the handle member support fitting 3, and a chain hook 8 fixed to the rear gate 1 passes below the shaft portion of the handle member 2 from the cutout window 3a. It is provided so that it sticks out. That is, the shaft portion of the handle member 2 is configured so that the chain engaging recess 8a of the chain hook 8 is fitted therein.

The shaft portion of the handle member 2 is a large and small diameter shaft portion having a small diameter shaft portion 2b provided in a part thereof, and when the handle member 2 is positioned inward, the small diameter shaft portion 2b is connected to the chain. As shown in FIG. 3, the rear gate chain 9 is prevented from entering and exiting by narrowing the gap between the entrance and exit 8b of the chain engaging recess 8a without facing the hook 8.

When the handle member 2 moves outward, the small diameter shaft portion 2b of the handle member 2 opposes the chain hook 8 to widen the gap of the entrance / exit 8b of the chain engaging recess 8a as shown in FIG. The rear gate chain 9 can be moved in and out.

Note that FIG. 5 shows the case where the handle member 2 is provided at the upper edge of the rear gate 1, and the housing 10 of the handle mechanism is installed at the upper edge 1a of the rear gate 1.
The handle support fitting 3 is fixed in the housing 10.

Therefore, when the handle member 2 is provided near the inside or outside of the upper edge of the rear gate 1, the installation location of the housing 10 is slightly different, and the structure of the handle hook and the chain hook does not change. Therefore, a description of a specific installation example is omitted.

Next, the operation of this embodiment having the above-described structure will be described. First, when the rear gate 1 is closed and the handle member 2 is engaged with the handle hook 7, as shown in FIG. The small-diameter shaft portion 2b moves outward against the urging force of the return spring 4, and the small-diameter shaft portion 2b is opposed to the chain engaging recess 8a of the chain hook 8 to
As shown in the figure, the gap between the entrances and exits 8b of the chain engaging recess 8a is widened so that the rear gate chain 9 can be inserted and pulled out.

When the handle member 2 is disengaged from the handle hook 7 and the rear gate 1 is opened, the handle member 2 is moved backward by the biasing force of the return spring 4 as shown in FIG. As a result, the small-diameter shaft portion 2b is displaced from the position facing the chain engaging recess 8a of the chain hook 8 to narrow the gap between the entrance and exit 8b of the chain engaging recess 8a, as shown in FIG. The above-mentioned gap is so small that the rear gate chain 9 cannot be inserted and cannot be pulled out.

Therefore, when the rear gate 1 is opened in a tilted or horizontal position, the rear gate chain 9 is locked by the chain hook 8
The rear gate chain 9 cannot be removed because it cannot be pulled out.

As described above, in the present embodiment, the rear gate chain 9 can be put in and out, that is, engaged and disengaged, from the chain hook 8 only when the handle member 2 is moved outward. When the rear gate 1 is hung and used with the rear gate 1 left open, the handle member 2 is inward and the chain hook 8
The rear gate chain 9 that is hung on is not detached.

[Effects of the Invention] As described in detail above, according to the rear gate structure with the rear gate chain in the vehicle carrier of the present invention, the chain hook is provided on the rear gate so that the rear gate chain can be attached to and detached from the rear gate. When the shaft part of the handle member is inserted inside the handle and the handle member protrudes outward and is engageable, the clearance between the handle member shaft part and the chain hook should be large enough to allow the rear gate chain to slip out. In addition, in the disengaged state of the handle member in which the handle member retracts inward, the shaft portion of the handle member has a small gap between the handle member shaft portion and the chain hook so that the rear gate chain cannot be pulled out. Since it is configured with large and small diameter shafts, handle members When the chain is removed from the hook and the rear gate is used with the chain hanging open, the rear gate chain will not be accidentally disengaged, which has the effect of greatly increasing safety in use.
