Technical field

The present invention relates to a disk tumbler tablet capable of forming a large number of key differences, capable of assembling various types of master keys and grand master key systems, and requires centralized management such as a hotel or a high-rise building. The present invention relates to a disc tumbler suitable for use in a building that has the following characteristics.

Rice field

Background art

Various types of disc tumbler tablets have been manufactured in the past, and the manufacturing process is simpler than that of pin tumbler tablets. Therefore, they are widely used for general door locks, vehicle locks, and the like.

Normally, one disk tumbler lock consists of an outer cylinder and an inner cylinder rotatably housed inside the outer cylinder. The inner cylinder is housed in a disc cartridge urged by a spring to project in the outer cylinder direction, Part of the disc must be inserted into the hole formed in the outer cylinder, and only when the appropriate key is inserted into the keyhole of the inner cylinder, the disc is moved properly and The inner cylinder is moved from the hole to the inside of the inner cylinder, and the inner cylinder and the outer cylinder are released from the fixing force of the disk, allowing the inner cylinder to freely rotate with respect to the outer cylinder. This is transmitted to the outside by means such as locking or unlocking.

In general, these disc tumblers have a smaller number of discs to be inserted into the same cylinder and a larger number of discs to be inserted to reduce the number of key differences in order to facilitate manufacturing. Is secured. In order to obtain more key differences, it is necessary to increase the number of discs to be inserted into the lock cylinder as described above. When setting a master key, it is basically required that there be many key differences. However, when seeking the perfection as a tablet, the strength of the cylinder was inevitably too long and the result was unsatisfactory and could not be obtained. It is widely known that the problem with a single disk tumbler is that it is difficult to increase the number of key differences, and that the range in which the master is assembled is limited.

As a means for obtaining a master key, a method is generally adopted in which the required number of disks set in a lock cylinder are extracted and used as a single change key cylinder.

To explain this example concretely, there are three types of discs to be inserted, and a cylinder is composed of six discs.

(1) 3 2 1 2 3 1

Is a master key disk combination. On the other hand, the change key cylinder has a structure in which any of the above six is removed.

(2) * 2 1 2 3 1

(3) 3 * 1 2 3 1

(4) 3 2 * 2 3 1

(5) 3 2 1 * 3 1

(6) 3 2 1 2 * 1

(7) 3 2 1 2 3 *

Is a disk configuration of a change key for the master key. The * mark indicates that the disk has been removed and the corresponding key hill has not been engraved.

The master key is engraved with the key strength so as to correspond to the [3 2 1 2 3 1〗] disk, so all combinations of the above disks (1) to (7) are properly moved and unlocked. Can be performed. While changing, the change key can only unlock the corresponding one cylinder, but not the other cylinders. The relationship was established.

Power> Shinaga, make a part of the change key that does not engrave the key, and confirm the master key. In this format, if multiple chunks are obtained, by examining them collectively, the notch of the key of the master key can be inferred, and the security effect is impeded irrespective of the precision of the lock. At the same time, there is a problem that the operation to reduce the number of disks to secure the master key deteriorates the resistance to picking.

Regarding this point, the situation is exactly the same for a general pin tumbler that secures the master key by inserting the master pin, and this is also the ability to analogize the master key from multiple change keys. At the same time, there is a danger that the picking resistance will be degraded for all the master key can be used.

In the present invention, it is intended to provide advantages such as high precision, a large number of key differences, mass productivity, ease of assembling a master key, complete prevention of picking, and the like to a single disk tumbler tablet that is easy to manufacture. At the same time, the aim is to eliminate the danger of analogy of the master key from the change key and to supply a single disk tumbler with improved picking resistance.

Disclosure of the invention

A conventional disk tumbler lock used the disk directly for locking between the inner and outer cylinders, and used the height of the key pile to move those disks to an appropriate position.

Therefore, depending on the type of disc inserted and the number of discs inserted, the number of different keys is limited S, and as a general household lock, about six discs are inserted into a single cylinder. Usually, there were about three types of disks.

The theoretical value of the key difference obtained in such a product is about 700, and hereafter, the key difference when the number of disks is increased is

7 discs Approx. 210

8 discs Approx. 6500

9 discs Approx. 1 900 10 discs Approx. 5 900

It is.

Increasing the number of discs increases the power of the key by ³ 'and the situation becomes desirable, but for that purpose, a long lock cylinder must be used, and a practical lock cannot be obtained. . Also, in the conventional product, since the disc is used to fix the inner cylinder and the evening cylinder, rotation given to the inner cylinder without inserting an appropriate key is necessary and sufficient for peaking the disc. It will give some pressure.

In the present invention, the disk is moved by the key pile, and the form of directly fixing the disk between the inner and outer cylinders is released, and a separate fixing means is provided for fixing between the inner and outer cylinders. I did it.

Also, several types of recesses are drilled on the side of the disc (see Fig. 6), and the discs are paired with the recesses facing outward (see Fig. 5). (See Fig. 3).

The fixing means between the inner cylinder and the outer cylinder is accommodated in the inner cylinder, and the fixing projection is fitted into the lock groove of the outer cylinder, and the fixing projection is accommodated in the inner cylinder by the panel. Between the fixing means and the disk, the concave force on the side of the disk ¾ When aligned in a straight line (see Fig. 7), a side bar as a detecting means that fits into all the concaves In addition, a ball shall be installed as a transmission means that always contacts both the sidebar and the fixing means.

According to this, when the concave force ^{s on the} side of the disk is at least outside the aligned position, the side par does not fit, and the ball abutting on the side continues to push up the fixing means, so that the fixing means The fixing projection cannot escape from the lock groove of the outer cylinder. Therefore, the lock is maintained.

When the recesses on the side of the disc are properly aligned as shown in Fig. 7 by using an appropriate key, the side bar will drop s into the aligned recesses, and there will be room between the ball and the fixing means. Is pulled into the inner cylinder by the action of the panel, and the fixing projection is released from the lock groove of the outer cylinder, and unlocking is performed. For example, even if a recess is made only at one location on the side of the disc, if the change of the drilling position is set in three stages, the same three types as the conventional disc can be obtained by itself. If two such recesses are drilled in a single disc, the number of key differences is double that of the conventional one. (Refer to Fig. 6.) It is clear that this is only a few key differences from the conventional product, but as a practically possible product, the recesses on the disk side mentioned above were drilled at two places. Since such discs can be used as a set of two discs (see Fig. 5) in 9 rows (18 discs), it is no exaggeration to say that the number of key differences is practically infinite in practical use.

If two recesses are made in a single disk and they are used as a set of two and aligned and used, one of the two locations must be used to move each disk properly. One of the recesses will be used, so if one of the four recesses of the pair of left and right discs is used at one of the upper and lower left and one at the upper and lower right, the other The lock can be operated without using the keypad. When used in this manner, the combination of the locations of the depressions is one of the four combinations shown in FIGS. 8 to 11.

The symbols on these drawings indicate the location of the recess,

L U is a depression above the left disk

L L is the lower recess of the left disk

R U is recessed above right disc

R L is a depression below the right disk

Respectively.

As is evident from the drawing, the combinations of depressions to be used are LU-RU (Fig. 8), LL-RU (Fig. 9), LL-RL (Fig. 10), LU-RL (Fig. 11). (Fig.) Since there are four ways to operate one lock in this way, using three of them,

(A) Grand master key operation

(B) Master key operation (0 Change key operation

The ability to perform each independently ^! It is easily possible.

For example, if we consider the master key in a typical hotel, assuming a simple situation,

(A) Grand Master Key A single key that locks and unlocks all rooms in the hotel.

(B) Master key A single key that can lock and unlock all rooms on one floor. One key is required for each floor.

(0 change key A key that locks and unlocks only one room.

It is assumed that three types of keys are required at a minimum.

To respond to these with the lock according to the present invention,

(A) Using [LU-RU] shown in Fig. 8 and combining them with the recessed positions common to all hotel rooms, it is possible to properly align all the recesses of [LU-RU]. The key that can be used is the Grand Master key.

(B) Use [RUL] shown in Fig. 9 and make [LL] common to one floor. Since [RU] is set in common for all rooms as described above, if a key that can be properly aligned in all the recesses of this [RU-LL] is the master key, the key All rooms in one door can be locked and unlocked.

(C) Using [LL-RL] shown in Fig. 10 and letting [RL] be different for each floor, and associating one combination of [RL] with one guest room, The key that can properly align all the recesses of [LL-RL] is a change key that can lock and unlock only a single room in all rooms of the hotel.

Further, even if the grand master key, master key and change key are set in this manner, in the case of one disk tumbler according to the present invention, another set of lock operation means is shown in FIG. 11. The combination of [LU-RL] remains untouched, and separate settings are still available.

If the present invention is expressed in another expression, the present invention includes four locks in one lock cylinder (inner cylinder and outer cylinder). A row of discs is installed, and only two of the four rows need to be operated for locking and unlocking operations. In this case, the remaining two rows of discs that are not used do not hinder the operation of the lock, which is completely different from a lock that simply has four rows of disks.

Further, in the present embodiment, an example is shown in which two recesses 24 are formed in one disk 11, but the number of the recesses 24 is arbitrary if necessary in design. In the embodiment, the case where two rows of discs are inserted into the inner cylinder has been described. By inserting only a row of discs, the function as a lock can be completely achieved. Of course.

Further, in the embodiment, the example in which the control means is constituted by a plurality of parts has been described. However, all or a part of these parts can be integrated so that the structure can be further simplified. You.

A further embodiment will be described with reference to FIGS. 12 to 15.

The drawing is a sectional view of a further embodiment of the disc tumbler lock of the present invention.

In the drawing, 3 is an outer cylinder of one disc tumbler, 10 is an inner cylinder, 6a is an outer cylinder 3 An inner cylinder sleeve that rotates integrally with the inner cylinder 10 inside.

The inner cylinder 10 is provided with a keyhole 13 force s at substantially the center thereof, and a disk hole 14 force is formed at right angles to the keyhole 13. In the case of this embodiment, the disk hole 14 is opened in a part of the hole 13, and a plurality of disk holes 14 are formed in parallel with each other. 0 is provided with an opening 15 for receiving the detecting means at right angles to the disc holes 14.

Each disc hole 14 accommodates a disc 31 force s' and is urged in one direction in the disc hole 14 under the action of a spring 12.

The portion of the disc 3 1 located in the keyhole 13 contacts the key ridge of the key 1 inserted in the keyhole 13, whereby the disc 31 is pushed up by the action of the spring 12. The key receiving unit is installed for 32 seconds.

A recess 33 is formed in a side edge 3 1 ′ facing the opening 15 of the disk 31. In the case of the present embodiment, the shape of the recess 33 is a U-shape formed by two sides perpendicular to the side 3 ′ of the disk 31 and one side parallel to the side edge 31 ′. Further, the recesses 33 are formed in two places on the side 31 'of one disk 31.

In the embodiment, the detecting means is composed of an upper moving piece 34 and a lower moving piece 35 which are slidably overlapped with each other. Each of the moving pieces includes indentation protrusions 36 and 37 that indent into the above-described recess 33 and has curved portions 38 and 39 that face each other.

The fixing means 41, which partially penetrates into the lock groove 40 formed in the inner wall of the outer cylinder 3 through the inner cylinder sleeve 6a facing the opening 15 It is accommodated in a depression 42 formed by facing curved portions 38, 39 provided on the piece 35. The transmitting piece 4 3 s is accommodated in the dent 4 2, and the transmitting piece 43 is always in contact with the upper and lower moving pieces 3 4 and 35, and the fixing means 41. .

The upper and lower moving pieces 34, 35 are constantly urged by a panel (not shown) in a direction to move away from the disc 31, and the tendency is transmitted to the fixing means 41 via the transmitting piece 43. Transmitted, fixing means 18 also tend to keep away from disk 3 1 Has been given.

In this way, for one or more disks 3 1 (although the number of disks 3 1 is generally plural according to common sense), each has a single upper moving piece 3 4 and a lower moving piece 3 5, but are pieces 4 3 and the fixing means 4 first force S prepared, these components are sectional shape is as shown in the first FIG. 6, the force ⁵ M preferable to form everything in a bar shape.

The embodiment of the present invention is completed by arranging two sets of the mechanisms formed as described above symmetrically in the inner cylinder 10 of one lock device (see FIGS. 12 to 15). . Of course, the lock can be operated by only one set of the mechanism, and it is optional.

Next, the operation will be described.

FIG. 12 shows the arrangement of internal components in a locked state in which the inner cylinder 10 and the outer cylinder 3 are fixed to each other by the fixing means 41 and the rotation of the inner cylinder is prevented.

In this state, the disc 31 is pushed down in the figure by the spring 12, and the upper moving piece 34 and the lower moving piece 35 are moved in the opening 15 by the action of a panel (not shown). The fixing means 41, which is urged toward the outer cylinder 3 and receives the force via the transmission piece 43, partially falls into the lock groove 40 of the outer cylinder 3.

If the user tries to rotate the inner cylinder 10 without using an appropriate key in this state, the fixing means 41 is pressed by the lock groove 40 of the outer cylinder 3, and the fixing means 41 is inserted into the opening 15 of the inner cylinder 10. The disc 3 1 is not aligned with the recesses 3 3, but the recesses 3 6, 3 7 of the upper moving piece 3 4 or the lower moving piece 35 fall into the recesses 33. And the movement of the disc 31 is stopped on the side 緣 31. Therefore, the fixing means 41 cannot escape from the lock groove 40, and as a result, the outer cylinder 3 and the inner cylinder 10 are fixed to each other, and the undesired rotation of the inner cylinder 10 is completely prevented.

Next, when the appropriate key 1 is inserted into the keyhole 13, the disk 31 is pushed up to an appropriate position by the key 1 as shown in FIG. Able to power 3 3 In the example shown in FIG. 13, the left disk 31 has upper recesses 33, and the other disk 31 has lower recesses 33. When the inner cylinder 10 is rotated from such a state, the fixing means 41 locks the locking groove 40 of the outer cylinder 3. (See Fig. 14) and move into the opening 15. At that time, the indentation protrusions 3 of the left upper moving piece 3 4 facing the recess 3 3 on the left disk 3 1 fall into the recess 3 3 on the left disk 3 1. The recess 37 on the right lower moving piece 3 5 facing the lower right recess 3 3 fits into the lower recess 3 3 on the right disk 3 1 The moving of the fixing means 4 1 is transmitted to the upper moving piece 3 4 on the left and the lower moving piece 35 on the right via the transmitting piece 4 3, as shown in FIG. 13. Both moving pieces move in the direction of the disc 31 by being piled by the action of a panel (not shown), and the shape force of the depression 42 formed by the upper and lower moving pieces 34, 35 is changed and fixed. The means 41 can be completely moved inside the shear line of the outer cylinder 3 and the inner sleeve 6a (see FIG. 15).

Therefore, the inner cylinder 10 is in a state where it can freely rotate, and this state is continued until the fixing means 41 and the force cylinder 40 enter the lock groove 40 next.

For example, in the case of this embodiment, assuming that the inner cylinder can be unlocked and locked by rotating the inner cylinder by 90 degrees, the state shown in FIG. 12 is passed through the states shown in FIGS. 13 and 14. The state shown in FIG. 15 is reached, and the state is further reversed to return to the state shown in FIG.

In this case, at the position shown in FIG. 15, since the fixing means 4 1 abuts on the inner wall of the force outer cylinder 3 and cannot move, the upper and lower moving pieces cannot slide. The key 1 cannot be removed from the keyhole 13 because the projections 36 and 37 are recessed in the recess 33 of the disk 31 and fix the disk 31.

When the operation of the lock is completed and the inner cylinder 10 is returned to the starting position in FIG. 13, the fixing means 4 1 force s' can be intruded into the lock groove 40 of the outer cylinder 3 which faces. Due to the action of a panel (not shown), the upper and lower movable piece slides toward the outer cylinder 3, and the recessed projection of the movable piece escapes from the recess 33 of the disk 31. The operation is transmitted to the fixing means 41 by the transmission piece 43, and the fixing means 41 partially indents into the lock groove 40, and the inner cylinder 10 and the outer cylinder 3 are mutually fixed.

As a result, the disc 31 is disengaged from the upper and lower moving pieces, so that the disc 31 can move freely. At this point, the key 1 is removed from the keyhole 13. Four

And ^five strengths.

In the drawing, the force is shown when the operation is performed by rotating the inner cylinder by 90 degrees, but as is clear from the drawing, the operation can be performed by rotating the cylinder by 180 degrees. First, the key groove 40 is installed at a location other than the one shown in the figure, so that the key 1 can be easily removed at that location. Industrial applicability

As described above, the disc tumbler tablet according to the present invention completely prevents the picking and can easily set a large number of master keys and grand master keys, and thus requires centralized management. Suitable for use as locks in large buildings.
