corresponds to

If the connecting body 15 is allowed to swing a little, it can be inserted into the insertion recess 5 more smoothly.

When the connecting body 15 is inserted into the insertion recess 5, it is pushed through the door against the force of the spring 4, and the slider 3 is pushed into the case 2.

Then, the slider 3 moves the lock ball 13 through the locking groove 11 in the guide groove 12 in the direction of the arrow.

When the lock ball 13 reaches near the center on the back side of the guide groove 12, the slider 3 stops, so pushing the door is stopped.

When the door is released, the slider 3 slides outward from the case 2 due to the force of the spring 4, but the lock ball 1
3 engages with the engagement recess A of the guide groove 12, and the slider 3 is locked within the case 2.

On the other hand, when the slider 3 slides inward of the case 2,
Since it moves the retaining ball 8 into the interior of the case through the support hole 7, the engaging ball 8 moves out of the recess 14 and into the inner surface of the case 2 and the bottom plate 9.

The retaining ball 8 that has come out of the recess 14 is pressed by the inner surfaces of the case 2 and the bottom plate 9, a part of which protrudes into the insertion recess 5, and fits into the connection recess 16 of the connecting body 15, causing the connecting body 15 to slide. Connect to 3.

Therefore, the door is fixed to the box body via the locking device 1 and maintained in a closed state.

To open the door, push the door again, move the slider 3 against the force of the spring 4, and move the lock ball 13 into the engagement recess A.
from there to the guide slope B side.

The lock ball 13 moves along the guide slope B, and when the lock ball 13 reaches the end of the guide slope, the door stops, so pushing the door is stopped.

When the door is released, the slider 3 moves the case 2 under the force of the spring 4.
The lock ball 13 reaches the frontmost position of the guide groove 12 as shown in FIG. 4, the slider 3 stops, and a part of the door is separated from the mouth of the box body.

Also, when the slider 3 slides outward from the case 2,
The retaining ball 8 inserted into the support hole 7 also moves to the recess 1.
4, the engagement ball 8 can be located almost entirely within the depth of the support hole 7 and the recess 14, and the coupling body 15 is released.

After that, open the door by hand after separating it from the opening of the box body using the slider 3.

That is, the slider 3 slides outward from the case 2,
When the door is separated from the box body, the connecting body 15 is already completely released from the locking device 1, and there is no resistance at all to separating the connecting body 15 from the slider 3 via the door, and the door is opened. There is no risk of shock to the box body.

In the case of a lid that can be rotated upwards, when the lid is pushed, the slider 3 lifts the lid, and from then on the lid can be opened by hand.

In this embodiment, the supporting part 6 formed on the bottom wall of the four insertion parts 5 is pushed by the tip of the connecting body 15, but as shown in FIG. The insertion recess 5 and the connecting body 15 can be locked together if they can be locked to each other.

The locking mechanism 10 for locking the slider 3 does not need to be limited to the embodiment, and may be any mechanism as long as it can be locked by pressing the slider 3 and unlocked by pressing it again. There is a mechanism disclosed in the official gazette.

This has a hook-shaped rotating plate with a slightly raised tongue and one end pivoted, and when the slider is pushed, a pin installed on the hook rotates the rotating plate and is caught on it, causing the slider to move. lock.

When the slider is pressed again, the tongue of the rotating plate overlaps the pin and releases the slider, and the slider is pushed out of the case by the spring as the pin passes under the rotating plate.

Furthermore, the locking mechanism disclosed in Japanese Utility Model Application Publication No. 52-144917 can also be used.

In this method, a protrusion is provided on the inner surface of the cylindrical body, and an engaging shaft made of a round bar is inserted into the cylindrical body.
As shown in the figure, a guide groove having an engaging recess and a guide slope is formed in an annular shape, and the guide groove is provided with a groove extending toward the back of the cylindrical body in the axial direction of the retaining shaft.

When this is used in the present invention, the retaining shaft is attached to the slider so as to be rotatable, and the cylindrical body is fixed to the bottom plate 9.

When the slider is pushed, the engagement recess of the engagement shaft catches on the protrusion of the cylindrical body, locking the slider and closing the door.

When the slider is pushed again, the guide slope hits the protrusion of the cylindrical body, the retaining shaft rotates, the protrusion is positioned in the groove in the axial direction, the retaining shaft is released, and the retaining shaft is retained by the spring. The mating shaft and slider are pushed out, separating a portion of the door from the box body.

As described above, the device of the present invention connects or releases the connecting body 15 fixed to the door or lid with the slide of the slider 3 to open and close the door, etc.
The connecting body 15 is connected to the slider 3 by a retaining ball 8 attached to the slider 3.

The engagement ball 8 is only inserted into the support hole 7 and can easily move in the depth direction of the support hole 7 without resistance, and the engagement ball 8 can be inserted by its own weight or by the connecting body 15. By moving the slider 3 from the recess 5 to the recess 14 side,
When the connecting body 15 is separated from the slider 3, there is almost no resistance when the connecting body 15 is separated from the slider 3.

Therefore, the door can be opened and closed quietly even when the box body is sensitive to shocks like an auto rack.

The retaining ball 8 inserted into the support hole 7 of the slider 3 is
Since the diameter of the support hole 7 on the side of the insertion recess 5 is made small so that it cannot pass through the insertion recess 5 side, even if the connecting body 15 is separated from the inside of the insertion recess 5, the engagement ball 8 will not come off. Moreover, since the connecting recess 16 is closed at least on the distal end side of the connecting body 15, the connecting body 15 can be held and released reliably.
