Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of LR Industry) The present invention relates to a tailgate I that can be opened and closed at the rear end of a vehicle loading platform.

(Prior art) Conventionally, as shown in Japanese Utility Model Application Publication No. 49-7614 and Japanese Utility Model Application Publication No. 55-135671, the tailgate of a cargo bed has a closed section type IJs with an inner plate and an outer plate. That is, some are configured to define a hollow portion between the inner plate and the outer plate.

In order to open and close this type of tailgate, there is a lock handle that can be accessed on the outer panel side, and a lock handle inside the tailgate (the hollow part defined between the inner panel and the outer panel).
A lock link is provided that is rotated by operating the long handle. When the lock handle is operated in a predetermined direction to rotate the lock link, the tailgate and the cargo platform are unlocked via a push-pull rod connected to the lock link.

However, in such a conventional tailgate, the inner plate and the outer plate are only joined at their peripheral edges, so the strength is weak, and especially the rigidity is low. This is extremely disadvantageous considering that the tailgate 1 on the loading platform becomes fragile and is subject to rough handling. In addition to this, vibrations (shock vibrations) occur on the inner and outer panels while driving, and the mechanical operation of the long link when operating the lock handle. It was undesirable that it would resonate within the hollow part and cause noise.

Furthermore, the workability of the lock link was extremely poor because the work to add more issues was carried out within the narrow hollow space using the extra issue hole opened in the inner plate.

In particular, during this work, there were cases where lock links, extra editions, and hats were dropped into the hollow space, and it took time to retrieve them. .

(Object 1-1 of the invention) The present invention solves the above-mentioned problems, and is excellent in terms of strength, especially rigidity, and 11,v (=
To provide a tailgate 1 for a vehicle loading platform which allows easy operation.

(Structure of the Invention) In order to achieve the above object, in the present invention, the outer plate and the inner plate are each narrowed down at the position of the long handle, that is, the plate surface portion of the outer plate and the inner plate, and the IJ- Four parts are formed and both recessed parts are joined together. Also,
The lock handle is disposed within the outer panel side four parts, while the lock link is disposed within the inner panel side opening 7;
The four parts on the inner plate side are covered with a concealing member.

(Example) In Fig. 1, ■ is the loading platform of the vehicle, and at the rear end,
A tailgate 3 is attached to the opening/closing opening A1 using a hinge 2. As is clear from FIGS. 2 and 3, this tailgate 3 has a closed cross-sectional shape with an outer plate and an inner plate.
In other words, a hollow portion A is defined between the two plates 4.5.

The outer plate 4 and the inner plate 5 are each narrowed down at the central portion of the loading platform in the two lateral directions, and the outer plate 4 has an outer plate side recess 6, while the inner plate 5 has four inner plate side recesses. 7 is formed. The plates 4 and 5 are in contact with each other at the four portions 6.7 (corresponding to the bottom walls of the recesses 6.7), and in this abutting state, they are joined as described below. ing.

A mechanism for opening and closing the tailgate 3 is provided in both the recesses 6.7, and this will be explained with reference to FIG. 4. A long handle 8 is disposed in the outer plate side four parts 6, and a lock link 9 made of a bell crank is arranged in the inner plate side recess 7. Also, a lock handle bracket 1 for holding the lock handle 8 is provided.
0 is arranged on the outer plate side four parts 6 side, while the long link 9
A long link bracket 11 for holding the long link is disposed within the inner plate side recess 7. And both Brakent lO and 11 have both plates 4 and 5 as their gates FIB 6.7
1114 bracket 10.11 using the port 12 and lug l-13 that pass through both plates 4.5 and both brackets l-10 and 11 while sandwiching them in the thickness direction at the bottom wall of
are fixed to both plates 4.5, and as a result, the outer plate 4 and the inner plate 5 are joined at the opening/ink handle 8.

The lock handle 8 has a substantially U-shape as a whole, and includes an operating portion 8a extending substantially parallel to the plate [m of the tailgate] and a pair of legs gBsb extending at right angles from each end of the operating portion 8a. In addition, the Dorukawa Braken l-10 for Ronkutsupe is also U-shaped, and its pairs of legs lOa pass through holes 14 formed in the outer plate 4 and inner plate 5, respectively, and pass through the inner plate. Side recess 7
It extends inward.

The pair of legs 8b of the lock handle 8 is also
, (passes through the 6L hole 14 and extends into the inner plate side four parts 7)
The leg portion 8b of the lock handle 8 is rotated in a direction relative to the leg portion 10a of the bracket 10 for opening/handle.
It is rotatably connected by a pair of pins 15 located on the axial line.

On the other hand, the lock link 9 has a lock link bracket 7.
) 11 is held by a leg portion 11a bent at a right angle toward the inner surface of the tailgate 3 so as to be able to rotate once. As shown in FIG. 5, one end of the - push-pull rod 16 is connected to one leg 9a of the lock link 9, and the other push-pull rod 17 is connected to the other leg 9b. One end is connected.

These push-pull ports 16 and 17 are inserted between the outer panel 4 and the inner panel 5 through through holes 18 formed in the inner panel 5 at the portions corresponding to the side walls of the four inner panel sections 7. It extends into the hollow part A. Of course, this Punshupuru Lot 16
．． 17 are attached to both left and right ends of the tailgate 3.
It is connected to a locked lock 19 (in FIG. 7, only the rod-shaped tip that is engaged with and detached from the loading platform 1 is shown). Note that this long lock 19 is for locking the tailgate 3 to the cargo platform 1 when it is closed, but any conventionally known lock may be used as appropriate. Therefore, detailed explanation thereof will be omitted.

As shown in FIG. 5, the lock link 9 further has a leg portion 9C for being pressed, and by further extending the leg portion 8b of the lock handle 8 from the leg portion 9C. The pressing portion 8C is in contact with the pressing portion 8C. Normally, the lock link 9 is biased by 4=1 in the direction opposite to the direction shown in FIG. 5 by a return spring such as a spiral spring (not shown), and when no other external force is applied, The lock 19 remains in the long state.

Here, the inner plate 5 is lightened over its entire surface, and due to reasons such as welding to the outer plate, etc.
A plurality of punch holes 20 are opened 1-1.

As shown in FIG.
At the same time, it is covered by a plate-shaped concealing member 21 fixed to the inner plate 5 with screws, for example. This concealing member 2
1 may be made of an appropriate material such as plastic or a metal cap, or if the concealing member 21 is large, it is preferable to form a reinforcing heat portion 21a in order to provide strength to the concealing member 21.

In the above-described configuration, in order to listen to the tail games 1 and 3, it is sufficient to grasp the operating portion 8a of the lock handle 8 and pull it up in the direction of the arrow in FIGS. 2 and 6. As a result, the lock handle 8 rotates around the pin 15, and its suppressing portion 8C acts on the pressed leg portion 9c of the lock link 9 as shown in FIG. is rotated in the direction of force 1"I' +jl in the figure, and this slow rotation is transmitted to the lock 19 via the push-pull rod and door 16.17 to open it. Conversely, when closing the tailgate, If you hold the tail case 1 to the closed position, it will lock automatically.

In the above embodiment, the concealing member 21 covers almost the entire surface of the inner plate 5, but it may cover at least the four parts 7 on the inner plate side. Further, the four parts 6.7 of the outer plate 4 and the inner plate 5 may be joined by, for example, welding or riveting. However, as in the embodiment, the lock handle bracket 1-10 and the lock link bracket +-
In manufacturing, the outer plate 4 and the inner plate 5 are joined using the bolts 12 and nuts 13, which also serve as fixing of the i i.
It is advantageous in terms of cost.

(Effects of the Invention) As is clear from the following two paragraphs, the present invention is characterized in that the outer plate and the inner plate are joined not only at their peripheral edges but also at the lock handle position, that is, at their plate surface. As a result, the strength, especially the rigidity, can be increased, and along with this, noise during driving and abnormal noise when operating the lock handle can be prevented.

In addition, the lock link removal work can be carried out under the four inner plate sides, a work space that is largely open on both sides, which is extremely advantageous in terms of workability.
Even if a long link or nut is dropped, it will not fall into the narrow hollow space between the outer plate and the inner plate, but will simply fall onto the work floor, making it easy to recover.

Furthermore, since the long handle is disposed within the four parts on the outer panel side, it does not protrude beyond the four parts on the outer panel side at all, or even if it does, it protrudes only slightly, which is preferable from the standpoint of safety and design.

Of course, the four parts on the inner plate side are covered by the concealing member, so
Unsightly things like lock links are not visible from the outside.
