Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a locking device for an aviation container. More specifically, it relates to improvement of a door locking metal fitting, which is commonly called "French drop".

(Prior Art) With reference to FIG. 3, a description will be given of the structure of a French dropper that has been widely used for locking doors of aviation containers (FIG. 4). Reference numeral 1 is a front plate of a lock, and a handle 3 is rotatably mounted in a vertical groove 2 of the front plate 1 by a pin 4. On the back surface of the front plate 1, a slider receiver 5 supports a slider 8 having a rod 7 on a head 6. The slider 8 has a bottomed tubular portion 8b at its center, and a coil spring 9 and a spring receiver 10 (FIG. 3 (b)) inside the tubular portion 8b.
And a pair of pin receivers 11 and 11 of the spring receiver 10 are inserted.
A pin 12 is inserted between them to engage with a hole at the tip of the handle 3.

The slider 8 integrated with the handle 3 is sandwiched between the rear surface of the front plate 1 and the slider pressing pin 13 of the slider receiver 5, and is vertically slidable.

In the French dropper having the above-described structure, the slider 8 is moved up and down by rotating the handle 3 up and down about the pin 4, and at the same time, the rod 7 integral with the slider 8 appears and disappears, and the frame member 15 It is designed to be locked and unlocked.

The conventional drop of France constructed in this way is the third
Even in the locked state as shown in Fig. (A), the face piece to which the French drop is attached (the door 18 in this embodiment)
When a downward load is applied to the frame, the French drop rod 7 and the frame 15 are disengaged (dashed line in FIG. 4).

(Problems to be Solved by the Invention) The present invention is intended to solve the defect of the conventional French drop. That is, a latch is provided on the French drop side, and a latching device that locks with the latch is provided on the locked body side,
By locking the latch and the latch at the same time when the French drop is locked, the locked body and the locked body are integrated at the time of locking to prevent the French drop from coming off.

(Means for Solving the Problem by the Invention) A slider having a rod fixed to the top is provided on the rear surface of the front plate so as to be slidable up and down, and a cylindrical portion having a bottom is projectingly provided on the rear surface of the slider. Incorporate a coil spring and spring receiver, and pivot the tip of the handle to the spring receiver with a pin.
Further, in the French drop in which the handle is pivotally attached to both sides of the vertical groove of the front plate with a pin, on the slider side a little from the line connecting the pin of the handle and the axis of the pin, and the distance r between the pins and the axis of the pin. The lower end of a bifurcated hook having a vertically long upper part is fitted into a hole formed at a side surface position of the handle on an arc defined by a radius r'or smaller, and the bifurcated hook is attached. The engaging member that engages with the upper hooking portion of the above can be engaged and disengaged by following the operation of the handle with respect to the engaging member.

(Embodiment) FIG. 1 shows a locking device A according to the present invention. The locking device A of the present invention is pivoted by inserting the lower end of a vertically long bifurcating hook from both sides into the holes 14, 14 provided on both sides of the handle 3 of the French lock having the conventional structure shown in FIG. I support you. In this case, the pivotal support position of the bifurcated metal fitting 16 with respect to the handle 3 is a distance r or less between the axis of the pin 4 supporting the handle 3 and the axis of the pin 12 on the spring bearing 10 side. It is desirable that it is on the circumference of a circle having a radius r ', and to the right of the line connecting the axis of the pin 4 and the axis of the pin 12 in FIG. 1, that is, on the slider side. Reference numeral 17 is a latching tool that engages and disengages the upper part of the bifurcated metal fitting 16 and is L-shaped and fixed to the frame body 15.

When the handle 3 is rotated upward from the position shown in FIG. 1 around the pin 4 by hand, the bifurcated metal fitting 16 moves upward by a substantially distance 2r, and is disengaged from the hook 17 (see FIG. 1). Dashed line).

(Operation) In order to unlock from the locking body shown in FIG. 1, 1) When the handle 3 is rotated upward, the slider 8 is lowered downward, and at the same time, the rod 7 integrated with the slider 8 is also lowered downward.

2) At the same time, the bifurcated metal fitting 16 is pushed up to release the engagement with the hook 17, and the bifurcated metal fitting 16 is manually tilted to the left in the figure.

3) Thus, the door 18 can be opened.

4) In the case of locking, it is possible to perform the reverse operation of the above 1) to 3).

(Effect) In the locked state, the French drop mounting side (door side) and the frame side, which is the locked side, are integrated by the engagement of the bifurcated hook 16 and the hook 17, so that even the French drop is possible. Even if the mounting side of is displaced downward, the frame body 15 also follows.
That is, the vertical displacement is restricted, and the locked state of the French drop is perfectly maintained.

Further, it is needless to say that the lateral displacement is restricted by the engagement of the bifurcated hook 16 and the hook 17.
