JP6911236B2 - Dial type locking device - Google Patents

Description

The present invention relates to a locking device such as a padlock or a chain lock that unlocks and locks by dial operation.

Padlocks and chain locks include dial-type and key-type ones.

Dial-type padlocks and chain locks have multiple dials in which symbols such as several types of numbers and letters are lined up, and the symbols on the multiple dials form a specific unlocking symbol string that serves as a PIN. Align with the reference position and unlock.
Then, it is locked by breaking it from the state where the unlocking symbol strings are aligned.

Dial-type padlocks and chain locks can be unlocked by anyone who knows the unlocking symbol string, so they can be shared by multiple people.

On the other hand, key-type padlocks and chain locks are unlocked using a key that is paired with the lock, so only the person who has the key can open the paired lock.

In many cases, the key is made of metal and it is possible to make a duplicate key.
If you prepare the required number of duplicate keys, it is possible for multiple people to use a pair of locks jointly.

Patent No. 3558772

Dial-type padlocks and chain locks are unlocked by arranging symbols on the dial and aligning the symbols at reference positions so that they form a specific unlocking symbol sequence.
However, since the number of symbol combinations is finite, even a person who does not know the unlocking symbol string can unlock when all the symbol combinations are performed when the symbol strings are aligned with a specific unlocking symbol string. ..

Further, in order to align the unlocking symbol strings, it is necessary to visually distinguish the symbols of each dial, and the place where the dial lock is used needs to be a bright place where the field of view is not obstructed.

On the other hand, key-type padlocks and chain locks can only be unlocked by the key owner, which has the advantage of crime prevention, but if the key is forgotten or lost, even the lock owner can unlock it. I can't do that.
In order to unlock it, it is necessary to prepare the actual key and the duplicate key again.
In addition, it is troublesome to carry and store the key, and the duplicate key can only be made by a specialist and cannot be easily obtained.

In order to solve these problems, the purpose is to provide a key that can be easily managed and obtained even though it is a dial-type locking device that is difficult to open for those who do not know the unlocking method.

The dial-type locking device of the present invention is a dial lock that unlocks a plurality of marks on the dial portion of the lock according to an arbitrary angle from a reference position, a relative angle, or a position of an arc length at that angle. Yes, a key is used to indicate the unlocking position.

The key indicates the angle between the reference position of the dial lock and the mark on each dial by the angle, the relative angle, or the arc length at that angle, and the size is the dial regardless of the material or shape. It may be flat or three-dimensional as long as the angle can be adjusted in comparison with the lock mark.
If there is a device for displaying an image, the electronic data of the image can also be used as a key.

By making the mark on the lock or key into a shape that allows you to judge the difference in shape and unevenness by touching it with your finger, you can unlock it even in a dark place where you cannot judge by looking at the symbol on the dial.

It is very difficult for a person who does not know the unlocking position to adjust an arbitrary angle, which is an analog amount, for all dials.
Since the reference position on the lock body and the mark on the dial are matched where there is no scale or display, the number of all combinations seems infinite, making it extremely difficult to unlock.
In addition, since the angles of the plurality of dials coincide with each other and the probability of unlocking is very low, the effect on crime prevention is great.

Any angle, relative angle, or arc length at that angle can be used as a key.
It can also be used as a key on paper showing the unlocking position graphically or electronic data of an image, and since the angle does not change even if it is enlarged or reduced, it can also be used as a duplicate key on paper that has been copied and printed. Even if it is copied by hand, it can be used as a master key.
A photograph of the dial at the reference position in the unlocked state can be used as a key to indicate the relative angle of the mark.
In particular, paper and electronic data are easy to carry, hard to lose, and convenient for storage. In addition, electronic data can be sent to another person immediately by using e-mail, and in an emergency, a substitute person can temporarily unlock the lock.

If the mark on the lock and the key can be distinguished by touching it with your finger, align the mark on the dial of the lock with the position of the mark on the key as if you touched it with your finger. By doing so, the angle is adjusted to the unlocking position, and the lock can be unlocked.
It is also convenient for use in places where the dial display is difficult to see or in dark places.

A mode for carrying out the present invention will be described with reference to the drawings.
The materials, shapes, and the like of the components described in the present embodiment are not intended to limit the technical scope of the invention to those alone.

FIG. 1 shows an example of a padlock-type dial lock according to the present invention and a key represented by a plane figure using paper or electronic data.

The lock body 1 includes an inverted U-shaped shackle 15 attached to the upper portion and a body portion 16. The body portion 16 has dials 121, 122, 123, 124, and the dials are marked with marks 131, 132, 133, 134.
Further, a mark 11 indicating a reference position is provided on the body portion located above the dial portion. In this example, marks 131 to 134 are indicated by vertical lines (|), and the reference position 11 is indicated by an inverted triangle (▽).
The mark 132 of the dial 122 of the dial lock 1 is not shown because it is located in a portion that cannot be seen in the drawing.

What is shown on the plane 2 is a key written on a board or paper, and the unlocking position of each dial is shown by using a figure.
The inverted triangle (▽) 21 indicates a reference position, and the straight line 25 drawn from the reference position 21 to the center point 24 is a reference line forming an angle with the straight line indicating the unlocking position. The straight lines 221, 222, 223, and 224 passing through the center point 24 are straight lines indicating the unlocking positions of the dials, and indicate the unlocking positions of the dials at an angle formed by the reference line 25.
Further, the tips of the straight lines 221 to 224 are numbered in the order from the upper side of the dial.
The circles 231 and 232 are concentric circles having different radii around the center point 24, and the radius is preferably a dimension equal to or larger than the radius of the dial lock.

The method of unlocking the padlock type dial lock 1 by using the key 2 of the plane figure is shown. First, the center of the circle of the dial lock 1 and the key 2 is aligned with the concentric circles 231 and 232 as a guide. Next, the reference position 11 of the dial lock 1 is adjusted so as to be located on the line of the reference line 25 passing through the reference position 21 of the key 2.
In a state where the reference position is aligned, the mark 131 of the dial 121 of the dial lock 1 is aligned so as to be located on the line of the straight line 221 indicated by ▲ 1 ▼ of the key 2 of the plane figure, and the dial 121 can be unlocked. To. The mark 132 on the dial 122 is on the line 222 indicated by ▲ 2 ▼, the mark 133 on the dial 123 is on the line 223 indicated by ▲ 3 ▼, and the mark 134 on the dial 124 is on the straight line 224 indicated by ▲ 4 ▼. When all of them are aligned on the line, the dial lock is unlocked and the shackle 15 moves upward.

The mobile terminal 3 is an example in which a key figure is used as electronic data 4 of an image. The unlocking method is the same as the above-mentioned key 2 of the plane figure.

The advantages of Example 1 are shown below.

Only the reference position (▽) and the mark (|) attached to each dial are displayed on the lock.
Since there is no other indication such as a scale on the lock, it is difficult for a person who does not know the unlocking method or the unlocking position to know where to put the mark (|) and unlock it.

Plane-shaped keys printed on paper or board can be easily copied to paper to create a duplicate key. Also, a copy on paper by hand can be used as a master key. For temporary purposes, the duplicate key copied on paper can be disposed of and discarded as paper immediately after use, making it easy to manage the duplicate key.

The key as electronic data of the image can be easily sent to the joint user. For example, when a group uses a warehouse, even if the key owner cannot go to the location due to an urgent need, he / she can send the electronic data to the mobile terminal such as the mobile phone, smartphone, or tablet computer of the person who is coming to the warehouse. Can unlock and use the warehouse.
Since the image data is a figure showing an angle, the angle shown in the figure does not change even if the size is changed by enlarging or reducing the image data, so that the image data can be used regardless of the screen size of the mobile terminal to be displayed.

2 and 3 show examples of a three-dimensional ring-shaped key and a key that approaches the arc length, using the chain lock type and padlock type dial lock according to the present invention.

The chain lock type dial lock 5 shown in FIG. 2 has a structure in which a main body 55 including a dial portion is attached to one end of a wire portion 54, and a connecting portion 56 connected to the main body 55 is attached to the other end. The wire portion 54 may be a chain of chains.
A star-shaped mark 531 is attached to the dial 52 near the reference position 51 of the main body 55, and a crescent-shaped mark 532 is attached to the next dial 52, so that all the dial marks are made into different shapes.
The mark 533 of the third dial 52 is not shown because it is located in a place that cannot be seen in the drawing.

The spiral ring-shaped key 6 shown in FIG. 2 has marks 621, 622, 623, and 624 having the same shape as the mark attached to the reference position 61 and the dial lock.
The star-shaped mark 531 attached to the dial lock 5 corresponds to the mark 621 attached to the key 6, the crescent-shaped mark 532 has the key 6 mark 622, and the diamond-shaped mark 534 has the key 6 mark 624. , Correspond to each.
Since the mark 533 of the dial lock 5 is not visible in the drawing, the mark 623 of the corresponding key 6 is also invisible and is not shown.
Each position of the marks 621 to 624 of the key 6 is arranged at a position that coincides with the angle formed by the marks 531 to 534 of the dial portion with the reference position 51 when the dial lock 5 is in the unlocked state with reference to the reference position 61. ..

A method of unlocking the dial lock 5 using the key 6 is shown.
First, the wire portion 54 of the dial lock 5 is passed through the ring shape of the key 6 by using the spiral gap of the key 6 so that the inverted triangles 51 and 61 indicating the reference positions are oriented in the same direction.
Next, the reference position 61 of the key 6 is aligned with the reference position 51 of the dial lock 5 in the horizontal direction in the drawing.
With the reference position aligned, align the mark 531 of the dial lock 5 with the position of the mark 621 of the key 6, the mark 532 of the dial lock 5 is the mark 622 of the key 6, and the mark 533 of the dial lock 5 is the mark of the key 6. In 623, the dial lock 5 is unlocked when the mark 534 of the dial lock 5 is aligned with the mark 624 of the key 6, and the connecting portion 56 is disengaged from the main body 55 including the dial portion to unlock.

FIG. 3 shows an example in which a three-dimensional ring-shaped keys 800 and 801 and a band-shaped plane figure key 802 are used for a padlock type dial lock 7.
The two keys 800 and 801 have different ring diameters, but at positions that match the angles formed by the reference position 71 and the marks 731, 732, 733, and 734 of each dial 72 when the dial lock 7 is unlocked. Marks 821, 822, 823, and 824 are arranged with reference to the reference position 811 of the key 800. The same applies to the mark attached to the key 801.
The mark 733 attached to the dial lock 7 and the mark 823 attached to the ring-shaped keys 800 and 801 are not shown because they are not visible in the drawing. The unlocking method is the same as the method described with reference to FIG.

The key 802 described on the strip-shaped paper in FIG. 3 indicates the unlocking position using the arc length.
The distance from the reference position 813 shown on the key 802 to the marks 841, 842, 843, and 844 is the angle formed by the reference position 71 of the dial lock 7 at the time of unlocking and the marks 731 to 734 attached to the dial on the surface of the dial portion. It is equal to the distance replaced by the arc length in.
When unlocking, the reference position 71 of the dial lock is aligned with the position of the reference position 813 of the key 802, and this strip-shaped paper is wrapped around the dial portion for use.
The key 7 is unlocked by aligning the marks 731 to 734 of each dial with the positions of the marks 841 to 844 described on the key 802.

The advantages of Example 2 are shown below.

The reference position 51 and the marks 531 to 534 on the dial lock 5 are marked with irregularities, and similarly, the marks 621 to 624 indicating the reference position 61 and the unlocking position of the key 6 are also marked with irregularities.
By touching with a finger so that the shape of the mark attached to each dial can be distinguished, the dial mark can be aligned with the position of the key mark indicating the unlocking position with the feeling of a finger.
In a dark place or the like, the dial lock 5 and the key 6 can be unlocked by aligning the marks with each other with the feeling of a finger without using vision.

The flat key 802 created according to the arc length can be easily copied on a strip of paper by hand to produce a duplicate key.

4 to 10 show examples of the structure of the dial portion according to the present invention. FIG. 4 is an embodiment of the structure of the dial 121 shown in FIG. 1, and a mark 131 is attached to an arbitrary position on the circumference of the dial 121.

5 and 6 are one embodiment of the structure of the dial 52 shown in FIG.
Marks 531 and 532 are added at arbitrary positions on the circumference of each dial 52.

7 to 10 are one embodiment of the structure of the dial 72 shown in FIG. As shown in Japanese Patent No. 3558772 of Patent Document 1 given as a prior art document, a lock gear is provided inside the dial portion to form a double structure so that the unlocking position can be changed. There is.
In this example, the lock gear 76 and the dial 72 have 24 mating ridges.

The advantages of Example 3 are shown below.

The marks 131, 531 and 532 shown in the examples of FIGS. 4 to 6 can be attached at 360 ° on the circumference of the dial without any restriction on the position.
Therefore, the unlocking position of one dial can be set by slightly increasing or decreasing the angle.

Although examples of fitting 24 ridges are shown in FIGS. 7 to 10, there is no limitation on the number of ridges.
The larger the number of ridges, the smaller the increase / decrease of the angle can be adjusted, and it is also possible to use the one with a different number of ridges for each dial.
In Patent Document 1, there is a restriction that the number of ridges matches the number of divisions on the dial surface, and it is necessary to manufacture the dial surface so that the display position and the lock gear do not deviate from each other. There are no restrictions on the positional relationship between the mark on the surface and the lock gear, and it can be manufactured without worrying about accuracy.

11 and 12 show an example in which the camouflage is displayed in the padlock type dial lock according to the present invention, and an example of a key indicating a relative angle.
This example can also be used for chain lock type dial locks.

FIG. 11 shows an example in which numbers 0 to 9 are evenly assigned to each dial. This number is camouflage and does not indicate the unlocking position.
In this embodiment, a boundary between the numbers 9 and 0 is set as a mark indicating the unlocking position. The dial 921 has a mark 931, the dial 923 has a mark 933, and the dial 924 has a mark 934. Is set.
Here, when the marks 931 to 934 come to the unlocking position, it is necessary to shift the reference position 11 by a slight angle so that the center of the number attached to each dial as a camouflage does not come.
Although the mark 932 is set on the dial 922, it is not shown because the mark 932 is arranged in a portion that cannot be seen in the drawing.

FIG. 12 is an example in which an English sentence is written on each dial.
This English text is camouflage and does not indicate the unlocking position.
In this embodiment, a period (・) at the end of the English sentence is set as a mark indicating the unlocking position, and the mark 951 is set on the dial 941, the mark 953 is set on the dial 943, and the mark 954 is set on the dial 944. Has been done.
Although the mark 952 is set on the dial 942, it is not shown because the mark 952 is arranged in a portion that cannot be seen in the drawing.

Both FIGS. 11 and 12 show the key 2 shown in FIG. 1 as a key.
The unlocking method is as described in Example 1.

FIG. 12 shows an example in which Photo 999 is used as a key to indicate the relative angle.
By using the camouflage symbol attached to the dial, it is possible to determine where the mark indicating the unlocking position is based on the relative positional relationship and angle. It can be used as a key by recording the state and position of the symbol at the reference position when the marks on all dials are moved to the unlocking position.
When unlocking, if the state and position of the symbol at the reference position are reproduced according to the recorded image, the mark on the dial is moved to the unlocking position and the lock can be unlocked.

The advantages of Example 4 are shown below.

In the example shown in FIG. 11, by shifting the reference position and the center of the numbers, even if a person who does not know the unlocking method performs all combinations of numbers as a conventional dial lock, the lock cannot be unlocked. ..

In FIG. 12, in addition to the period, for example, the alphabet “s” of the English word “is” can be set as a mark.

In the examples of FIGS. 11 and 12, a person who does not know the unlocking method cannot determine which of the marks 931 to 934 and 951 to 954 to be adjusted to the unlocking position. Even if the key 2 can be obtained illegally, it is difficult to unlock it without knowing the matching mark.

It can be used as a key simply by taking a picture of the state of the dial at the reference position when it is unlocked and saving it as an image. A photograph as a key indicating a relative angle can be treated as electronic data in the same manner as a graphic image.
