BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a striker cover for a striker provided on a vehicle floor for locking a back door, and more particularly to a striker cover opening / closing device for opening and closing the cover in conjunction with the back door.

[0002]

2. Description of the Related Art In a vehicle provided with a box-shaped body 1 as shown in FIG. 3, a back door (double-opening type in the illustrated example) 2 for opening and closing the body 1 is provided at a rear end opening thereof. As a back door, there is a so-called one-touch type back door which is automatically locked when the door is closed. The one-touch type back door is usually provided with a striker 3 at the rear end of the vehicle floor 11 and a lock member (not shown) at the lower end of the back door 2 as shown in FIG. When the door 2 is closed, the lock member engages with the striker 3. The striker 3 is generally installed in a concave portion 12 formed in the floor 11 because the striker 3 protrudes from the floor 11 and becomes an obstacle during loading.

[0005] Incidentally, loading on the box-shaped body 1 is shown in FIG.
As shown in (A), a pallet 9 loaded with goods is often carried into the body 1 from the lifter 8 using the lifter 8. In this case, as shown in FIG. 5 (B), the wheel 90 of the pallet 9 is
2 and the pallet 9 may be difficult to move. For this reason, a striker cover that covers the recess 12 provided with the striker 3 is used.

[0004]

However, since the striker cover hinders the entry of the door lock member, the striker cover must be opened and closed each time the door is opened and closed. It is extremely troublesome.

Accordingly, an object of the present invention is to provide a striker cover opening / closing device in which a striker cover is opened in conjunction with a door when the door is closed, and the striker cover is closed in conjunction with the door when the door is opened. It was done.

[0006]

Apparatus of the present invention Means for Solving the Problems] has its front edge the striker cover 5 which covers the striker 3 installed in the recess 12 of the vehicle floor 11, as shown in FIG. 1
At the center, the back door 2 having the lock member 4 is tilted rearward while being flipped up and mounted rotatably.
A cam that forms a rising slope , receives the free end 51 of the striker cover 5 when the back door is closed, guides the free end 51 up and down as the back door 2 is closed and opened, and raises and lowers the striker cover 5. A guide member 6 having a surface 61 is provided.

[0007]

As shown in FIG. 2, when the back door 2 approaches the closed position when the door is closed, the lower end of the cam surface 61 of the guide member 6 is attached to the free end (rear end) 51 of the striker cover 5 , and
Engage to receive . When the back door 2 is further closed, the free end 51 is guided by the cam surface 61,
The striker cover 5 rises while sliding on the top, and stands up.
This enables the lock member 4 to be fitted to the striker 3.

When the door is opened, as the back door 2 is opened, the free end 51 of the striker cover 5 is guided by the cam surface 61 of the guide member 6 by its own weight and descends.
The striker cover 5 falls down and is closed. This makes it possible to smoothly carry the pallet from the lifter into the vehicle.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1A, a rear opening of a box-shaped body 1 of a vehicle is opened and closed by a pair of left and right back doors 2 of a double-opening type. Left and right back door 2
Has the same structure and lock mechanism, and only the right side will be described below.

A recess 12 is formed in the rear end of the vehicle floor 11 at a position slightly to the right in the center in the width direction as shown in FIGS. 1B and 2, and the striker 3 is fixed in the recess 12. . The striker cover 5 is installed in the recess 12 provided with the striker 3 so as to cover the same. The striker cover 5 has a front edge connected to a front edge of the recess 12 by a hinge 55, and the striker cover 5 has a rear end 51.
Is a free end and can be flipped up and rotated freely. The free end 51 of the striker cover 5 is bent downward in a C-shaped cross section.

On the other hand, on the inner surface of the back door 2, FIG.
As shown in (A) and FIG. 1 (C), a reinforcement 7 is provided in the vertical direction at a position near the open / close end. At the lower part of the reinforcement 7, there is provided a lock member 4 which engages with the striker 3 when the door is closed to lock the door.

Further, a guide member 6 is fixed to the back door 2 at a lower portion of a side surface of the reinforcement 7 on the door mounting side. The lower half of the guide member 6 protrudes forward from the reinforcement 7, and its front edge is inclined rearward.
The cam surface 61 is an inclined surface that rises while being inclined.
The positional relationship between the guide member 6 and the striker cover 5 is such that the lower end of the cam surface 61 of the guide member 6 abuts on the free end 51 of the striker cover 5 when the door 2 is closed. The cam surface 61 has a gentle concave curved surface.
The lower end corner 611 of the cam surface 61 is formed in a rounded shape, and the corner 611 is slightly lower than the free end 51 of the striker cover 5 that forms a curved surface when the door is closed. come in contact with the
To receive this .

In the striker cover opening / closing device configured as described above, when the back door 2 is closed, the lower end 611 of the cam surface 61 of the guide member 6 comes into contact with the free end 51 of the striker cover 5. When the back door 2 is further closed and the door end moves forward while pivoting, the free end 51 of the striker cover 5 becomes a cam surface 61 as shown in FIG.
The slider cover 5 is guided by this and moves upward while sliding upward, and the striker cover 5 stands up. Then, the lock member 4 enters the recess 12 from behind, and the back door 2 is locked by fitting with the striker 3.

Next, when the door is opened, the door lock is released by pulling the door handle, and the back door 2 is opened. At this time, the free end 51 of the striker cover 5 is lowered by its own weight along the cam surface 61 of the guide member 6 to close the recess 12 and become flush with the floor surface.

Therefore, the pallet 9 (FIG. 5) has its wheels 9
0 is smoothly carried into the vehicle body from the lifter 8 without falling into the recess 12.

As shown in FIG. 2, the striker cover 5 is installed such that the standing posture 5 'when the back door 2 is completely closed is inclined backward. The lower end surface of the striker cover 5 abuts on the edge portion 14 of the floor 11 at a position 5 ° standing up to about 10 ° before the vertical,
Further standing is regulated. This is to prevent the striker cover 5 from falling forward beyond the vertical position due to inertia when the back door is closed.

As means for preventing the striker cover 5 from falling forward, a hinge 55 serving as a rotation center of the striker cover 5 is used.
Alternatively, a spring may be provided on the striker cover 5 to urge the closing direction rotational force.

While the striker cover opening / closing device for the right back door striker has been described above, the left device has the same structure.

[0019]

According to the present invention, as described above, the striker cover interlocks with the opening and closing of the back door, opens when the back door is closed, enables the door to be locked, and opens when the back door is opened. Since the door is closed, loading into the vehicle can be performed smoothly. As described above, since the striker cover is automatically opened and closed, it is not necessary to manually operate the striker cover every time the door is opened and closed, and the workability is greatly improved.
