However, the base end of the input shaft 31 is a non-blind sleeve that accommodates the spline portion at the tip of the connecting shaft 21, and the input shaft 31 is tightened by locking from the outer periphery via a ring 31a and a pole 31b. (Figure 4).

The first to fourth bevel gears 32a, 32b...
The first bevel gear 32a is attached to the input shaft 31, and the second bevel gear 32b is attached to the output shaft 33 perpendicular to the input shaft 31.

The input shaft 31 and the output shaft 33 each have a bearing 3
It is rotatably supported on the casing 32 via bearings 33a, 33a. However, the bearing 31d that pivotally supports the tip of the input shaft 31 is housed in a male-threaded bearing holder 34 that is screwed into the cap member 34a, and the bearing holder 34 is movable and adjustable in the axial direction of the input shaft 31. Moreover, it can be locked with a lock nut 34b. Bearings 33a, 33

A tumbler portion 40 is connected to the tip of the output shaft 33 via a mounting bracket 40a.

The tumbler section 40 stores four tumblers 41, 41, etc. for setting setting numbers, and the tumblers 41, 41...
... are removable from the case 42 together with the back cover 43. Each of the tumblers 41, 41, etc. is engraved with a scale of 100 equal parts, and by setting a predetermined setting number, the tumblers 41, 41, etc. move in and out of the bold 44 when driven to rotate in a predetermined rotation direction via the output shaft 33. , forming a so-called -100 million conversion code lock.

The bolt 44 is engaged with a rotary plate L1 that is interlocked with the bolt mechanism L..., and as long as the bolt 44 protrudes from the case 42, the bolt mechanism L... can be unlocked. First, it is assumed that the bolt mechanism can unlock L...- only when the bold 44 is retracted into the case 42.

Two sets of combination lock devices having such a configuration are arranged one above the other and installed in a moving box B of a storage (FIGS. 2 and 5). At this time, each gear box 30 and the tumbler section 40.
are installed in the space S between the front panel B1 and the shelf D2 that stores the safe deposit box, and are connected to the dial operation section 10 via the joint unit 20 and the connecting shaft 21, respectively. . Further, on the side of the space S facing the fixed box body A, a lock mechanism L... is protruded and an opening/closing lid S1 is provided. However, the lock mechanism at this time, L
...are two sets of tumblers 40.400 bold 44
．． It has two rotary plates L1 and Ll that engage with the respective bolds 44, and can be unlocked only when neither of them engages with the corresponding bold 44.

Since the input shaft 31 and output shaft 33 of the gear box 30.30 are perpendicular to each other, the tumbler portion 40.40
Both can be installed so that the back cover 43 is located in the immediate vicinity of the opening/closing cover S1 (Fig. 1). Therefore, the movable box body B is separated from the fixed box body A, and a passage C is created between them.
If , access to the tumbler part 40.40 is as follows.
It's extremely easy.

The joint unit 20 linearly connects the output shaft 13 of the dial operation section 10 and a connecting shaft 21 that is connected to the input shaft 31 of the gear box 30 by spline connection (FIGS. 1 and 3).

If the bolt 27 tightening the slit 23a of the output block 23 is loosened, the connecting shaft 21 and the output block 23 can be rotated relative to each other, so the worm 25 is rotated in this state, and the worm wheel 26, the connecting shaft 21 is connected to the joint unit 20.
Only can be driven rotationally. At this time, connecting shaft 1
3 and the joint unit 20 are the input side block 22
Since they are fixedly connected unless the bolt 27 tightening the slit 22a is loosened, the relative rotation between the output shaft 13 and the connecting shaft 21 can be adjusted by rotationally driving the worm 25.

On the other hand, the output shaft 13 is connected to the dial operation section 10,
The connecting shaft 21 is connected to the input shaft 31 of the gear box 30, and the latter is further connected to the tumbler section 40 via the output shaft 33 of the gear box 30, so that the joint unit 20 is , the scale section 12 of the dial operation section 10 and the tumbler 41.41 of the tumbler section 40.
This means that accurate scale adjustment can be made between... After completing the scale adjustment, it is sufficient to tighten the bolt 27 corresponding to the slit 23a of the output block 23 to lock the relative rotation between the output block 23 and the connecting shaft 21, and then the joint unit 20
By operating the dial operation section 10, the entire
It rotates together with the output shaft 13 and the connecting shaft 21.

The rotation of the input shaft 31 in the gear box 30 is caused by the first rotation,
Output shaft 33 via second bevel gears 32a, 32b
However, at this time, the fourth and third bevel gears 3
2d and 32c also form a rotation transmission path between them at the same time. On the other hand, the third and fourth bevel gears 32c and 32d move in the axial direction via the bearing holder 34 and the adjustment shaft 35, respectively, to adjust the depth of meshing with other bevel gears. The first
Even if the second bevel gears 32a, 32b are worn and the backlash between them becomes excessive, this effect can be easily eliminated. Moreover, at the same time, the magnitude of the required rotational torque when operating the dial operating section 10 can also be set appropriately.

Another embodiment of the joint box 20 may be constructed by a combination of an upper block 28 and a lower block 29 (FIG. 6). The total number of parts can be reduced. Further, the worm wheel 26 may be fitted onto the output shaft 13 of the dial operation section 10 instead of the connecting shaft 21. In this case, the connecting shaft 21 may be fixedly connected to the joint unit 20. good.

Note that the joint unit 20 generally has a connecting shaft 21
It is sufficient that the relative angle between the output shaft 13 and the connecting shaft 21 can be arbitrarily adjusted within the range of the spline pitch angle θ (FIG. 4).

Further, the present invention is not limited to an open/close storage consisting of a fixed box A and a movable box B, but can be widely applied to any other type of storage using a combination lock device. It shall be possible. For example, the fixed box A may also be movable (and what is stored inside is not limited to a safe deposit box, but also a rack for simply storing documents, etc.).
It may be a drawer, shelf, etc. Furthermore, gear box 3
It goes without saying that two or more 0 may be used in series, and two or more bending points may be provided in the rotation transmission path between the dial operation section 10 and the tumbler section 40.

As described in detail, according to the present invention, a gear box in which the input shaft and the output shaft are orthogonal to each other is interposed between the dial operation section and the tumbler section, thereby creating a rotation transmission path between the two. By bending the tumbler part at a right angle, the tumbler part can be installed at a location convenient for access, and therefore, the setting number can be easily changed without creating any extra dead space in the space in which the tumbler part is stored. In addition, part of the bevel gear built into the gearbox can be adjusted by moving in the axial direction, making it possible to appropriately adjust the backlash and required rotational torque between the input and output shafts. This has the excellent effect of allowing easy dial operation and a proper feeling of use.
