The fastener 5 inserts the first arm 16a of the support spring 16 into the long hole 57 of the bracket 10 and inserts it into the rear end of the hook guide 11, and locks the second arm 16b of the support spring 16 with the other long hole 58. Can be attached.

In the assembled state, the upper end of the shaft 23 protrudes from the upper surface of the cover 24. When the key 40 is inserted into the key groove 42 of the shaft body 23 and rotated left and right, the protrusions 46 of the key 40 alternately engage with the engagement protrusions 35 and 36 of the slider 22, so that the slider 21 Slide back and forth. As described above, the pair of engagement protrusions 35 and 36 is an element of a mechanism that converts a rotational movement into a reciprocating linear movement of the slider.

For example, as shown by a solid line in FIG.
Is rotated in the counterclockwise direction, one surface of the key projection 46 engages with the front engagement projection 35, and the slider 21 moves forward. Therefore, the locking piece 33 is provided with a slit 49 of the cover.
Come down below. This is the locked position of the slider 21.
At this time, when the protruding piece 48 of the knob 13 is placed inside the lock as shown in FIG. 2, the locking piece 33 of the slider is inserted into the locking hole 51 of the protruding piece 48, and the knob 13 is restrained in that state.

On the other hand, when the key 40 is rotated clockwise from the state shown in FIG. 1, the other surface of the projection 46 of the key is engaged with the engagement projection 36 on the rear side, and the slider 22 is retracted. At the same time, the locking piece 33 moves backward from the slit 49 and comes out of the locking hole 51. This state is the open position of the slider 22. In this state, the knob 13 can be freely raised and fall down.

When the slider 22 is in the locked position, the small projection 26a at the front of the base 21 is inside the elongated hole 34, and the small projection 26b at the rear is formed by the rising piece 32 at the rear of the slider 22. It is outside. In this state, as shown in FIG.
6b, and since the slider 22 is pressed by the cover 24, there is no play. When the slider 22 is retracted from that state, the slider 22
Retreats while climbing over the front and rear small protrusions 26a and 26b, and when reaching the rear end, the rear small protrusion 26b is elongated.
4, the front small protrusion 26 a comes to the outside of the front rising piece 31. Therefore, for the user who turns the key 40, a click feeling is given based on the operation, and the operation feeling is good. Also, the slider 22 is stably locked at the open position. The same applies to the case where the slider 22 is advanced from that position.

The front and rear rising pieces 31 and 32 are the cover 2
4 and the base 21 are pressed and held between them, so that the above-mentioned click feeling and locking action are ensured.
The pressing of the rising pieces 31 and 32 by the cover 24 need not always be performed. That is, there may be some gaps at all times, and the slider 22 may be pressed only when the slider 22 gets over the small projections 26a and 26b. Since the front and rear rising pieces 31 and 32 are free at the sides and the upper end, they slightly bend, facilitating the above-mentioned overcoming. However, the material of the slider does not need to be very flexible, and may be ordinary mild steel. The small projections 26a, 2
6b is preferably rounded as shown in FIG.
This makes it easier to get over.

The lock 15 described above has a base 21
Since there are only the four points of the slider 22, the shaft 23, and the cover 24, the number of the locks is smaller than that of the conventional lock, and the assembling work is also simple. Since a spring is not particularly used, complicated labor such as assembling while bending the spring is not required. In addition, since the slider 22 does not reciprocate but reciprocates linearly, the locking hole 52 of the projection 48 of the knob 13 can be reduced. Therefore, since the protruding piece 48 is also small,
3 is easy to turn.

Next, the operation of the entire lock device will be described with reference to FIGS. First, with the fastener 5 slightly tilted and the tip of the hook plate 12 raised,
The lid 2 is put on the main body 1 of the container case. At this time, there may be some gap S. Next, as shown by an arrow P, when the fastener 5 is tilted horizontally, the hook portion at the tip of the hook plate 12 faces the receiver 6. Picking in this state 1
When the hook 3 is rotated by 180 degrees, the hook plate 12 is retracted as shown by the arrow Q, and the hook portion is securely engaged with the receiving member 6 as shown in FIG. 6, and the main body 1 and the lid 2 are sufficiently closed. .

Next, when the knob 13 is turned down as shown by the arrow R in FIG.
The inside enters through the slit No. 4 (49 in FIG. 1). At the same time, the upper end of the shaft body 23 is fitted into the shaft hole 52 of the knob 13,
The upper surface of the shaft 23 is substantially flush with the upper surface of the knob 13. This facilitates the positioning of the knob 13 and the insertion of the key 40. In this state, as shown in FIG.
When the center portion 41 of the key 40 is inserted into the key groove 42 of the shaft 23, the protrusion 46 of the key 40 enters the inside through the notch 53 of the knob 13 and the notch 47 of the cover 24, and
5, 36 can be engaged. Thereafter, as described above, the key 40 is rotated counterclockwise in FIG.
The locking operation is completed by engaging the projection 3 with the projection 48.

When unlocking, after the key 40 is inserted, the engagement between the locking piece 33 and the protruding piece 48 is released by turning the key clockwise. Thereby, the knob 13 can be raised freely. Then, the lid 13 is opened by rotating the knob 13 in the reverse direction to advance the hook plate 12, tilting the fastener 5 to avoid interference with the receiver 6, and then opening the lid 2.

In the above embodiment, the lock 15 is connected to the bracket 1
Since the hook guide 11 is attached to the rear part of the hook, there is an advantage that the hook guide 11 can also be restrained at the time of locking. But hook guide 1
You may make it attach a lock to 1. Further, since the moving direction of the slider is perpendicular to the moving direction of the hook plate, there is an advantage that the rotation of the knob can be reliably restrained. However, they may be in the same direction or in an inclined direction.

Further, in the above-described embodiment, the slider 22
A lock piece 33 is projected from the knob 13, and a lock hole 51 for engaging with the lock piece 33 is provided in the protrusion 48 of the knob 13. However, if desired, a locking hole may be formed in the rising piece 31 of the slider 22 or the like, and the lower end of the protruding piece 48 of the knob 13 may be bent to form an engaging projection that engages with the locking hole. Further, both the slider 13 and the projecting piece 48 may be provided with engaging projections. That is, it is only necessary that the engaging portions of both can engage and disengage in accordance with the forward / backward movement of the slider.

The lock according to the present invention can be used for other purposes such as bags and bags by taking advantage of its simple structure and small number of parts in addition to the lock for fixing the knob of the container case. Can be.
