Description

Specification

Double key structure

Technical field

[0001] The present invention relates to a double structure of a key that can be used in any locking device such as a front door, an automobile and a safe.

Background art

[0002] In recent years, car theft crimes have been increasing rapidly, and organized crimes by the thieves are particularly noticeable. Furthermore, the rapid increase in car theft is a problem that may lead to a disadvantage for the entire car insurance policyholder, such as attracting secondary crimes caused by stolen cars and increasing car insurance premiums. The same is true for the sudden increase in damage caused by intrusion into buildings due to picking. About 70% of damage due to intrusion is a serious problem that threatens safe living because ordinary houses are subject to damage. . Therefore, a complicated structure is adopted for the lock, for example, it is impossible to rotate the thumb turn or cam, and the key is difficult to duplicate, such as an automobile key with an inner groove, bias cut, immobilizer, etc. However, the current situation is that these crimes can be dealt with by using dimples in three or more directions for housing, and making the key-key production with a key number restricted more than a certain condition.

[0003] In this way, the key makes it difficult to duplicate, and criminals cannot easily unlock it. Or, even if it is necessary for use by multiple people, such as family members, there may be a problem in that copying becomes difficult. Therefore, if the key is difficult to duplicate and the number of keys held is less than the required number of people, it is generally hidden under a mailbox or flowerpot near the entrance, or by a car. There are many cases in which a single key is shared with the family by attaching it to the bottom of the car body with a magnetic case.

[0004] However, in condominiums such as apartments and condominiums, hidden places are also limited, and the thief searches for a key using this as an odd coin. Retrieval key search is relatively large among the intrusion methods of vacant nests, so even if a lock or key is devised, it makes no sense. In addition, this method may also promote crime.

[0005] When the key itself is stolen or lost, it is necessary to replace not only the key but also the key cylinder in order to prevent intrusion and theft. When a powerful key cylinder is replaced, for example, for automobiles, the doors for starting and for doors, for motorcycles, unlocking for starting and fuel tanks and small containers will become individual keys. In addition, powerful cars and motorcycles are often suspected of being stolen cars, and the price of used cars must be set low, resulting in greater disadvantages for transferors and traders. Furthermore, in the case of automobiles and the like, replacement is extremely difficult and expensive compared to building doors.

[0006] Therefore, various techniques have been developed in order to avoid the automobile theft and the intrusion to the house as described above. For example, in the invention (Japanese Patent Laid-Open No. 2002-364214), the lid and the storage case are locked by a padlock-like dial key type lock mechanism and a cylinder key type lock mechanism. However, in this case, if the hidden place of the key is clearly indicated and the lid is destroyed, the key can be easily obtained. There is also a door double lock (Patent 3447263) in which the key hole of the first lock of the door is covered with an openable / closable lid and the lid is opened by the second lock. However, it is cumbersome to carry the two keys separately, and in the case of loss, etc., it is usually not possible to obtain two keys at the same time. In addition,

There is a vehicle user authentication system that performs dual authentication using biometric information to improve vehicle security (Japanese Patent Laid-Open No. 2003-182528). This user authentication system compares the fingerprint information obtained with the user identification information storage medium power and the user's fingerprint that is actually detected, and releases the door lock of the car when they match. Means and user identification information storage medium power The device is provided with means for comparing the obtained vein pattern information with the actually detected vein pattern of the user and allowing the engine to start when they match. It is. However, a configuration that recognizes fingerprints on the vehicle body side can be difficult to use, such as being unable to pass a key to another person away from the car. Therefore, any of the above-mentioned techniques has proposed a technique for effectively solving the above problems.

In addition, as a synergistic effect of powerful effects, it is not necessary to replace the lock, and it is possible to improve the security level to a certain level without changing to a security door equipped with an advanced locking device. It is also a target.

[0016] Furthermore, according to the double key structure that is effective in the present invention, the mechanism in which the engaging portion protrudes by the input of the personal identification number as the authentication operation is made a mechanical structure, so that the cost performance is excellent. It is possible to provide a double key structure.

[0017] Furthermore, according to the double key structure of the present invention, the protruding mechanism employs a mechanism in which the engaging portion protrudes by the recognition of the user's fingerprint as an authentication operation, so that other than the specific user. It is possible to provide a double-key structure with extremely high crime prevention properties that cannot be used by any person.

BEST MODE FOR CARRYING OUT THE INVENTION

[0018] The double key structure 1 according to the present invention is characterized in that it has a mechanism capable of unlocking and closing a key for the first time by performing a predetermined authentication operation. Hereinafter, an embodiment of a double key structure 1 according to the present invention will be described with reference to the drawings. FIG. 1 (a) and FIG. 1 (b) are perspective views showing a first embodiment of a double key structure 1 according to the present invention, and an engaging portion of a key that fits into a cylinder lock. It shows that 2 has a protruding mechanism for protruding from the main body 3. Fig. 1 (a) shows a state in which the engaging portion 2 protrudes from the main body 3 by the protruding function, and Fig. 1 (b) shows a state in which the engaging portion 2 is stored in the main body 3. Yes. The engaging portion 2 is not particularly limited as long as it is for a cylinder lock.For example, in addition to the standard shape, the engaging portion 2 can have any engaging shape such as reversible, inner groove, bias cut, dimple, and immobilizer. It is possible.

[0020] The main body 3a is provided with a projecting mechanism for projecting the main body force by performing a predetermined authentication operation in the authentication operation unit. In the drawing, an embodiment is shown in which a password input method by the password number operation unit 5a such as a rotary dial is adopted as the authentication method of the authentication operation unit, but the present invention is not limited to this. It is also possible to use a fingerprint recognition method of the user by the fingerprint recognition unit 5b described later. When the password input method is adopted, the password entered in the password operation section 5a is a number, alphabet, or a combination of these in consideration of theft or loss. Therefore, it is desirable to input at least 4 digits. Structurally, it is possible to change the security code mechanically or electronically by using the unlocking mechanism by inputting the security code of other information similar to the conventional dial padlock. It is effective.

[0021] Note that a structure in which the main body 3a is provided with the engaging portion fixing device 7 is also conceivable. The engaging portion fixing device 7 is a device that prevents the engaging portion 2 from being stored due to some impact or malfunction during use. That is, when the key is being used, for example, when the key of the automobile is inserted into the cylinder lock for starting the engine, the engaging portion fixing device 7 is operated in consideration of safety for prevention of danger. The engaging portion 2 can be mechanically locked.

[0022] Further, after use, for example, when the car key is removed from the cylinder lock for starting the engine, the engagement portion 2 recognizes that the cylinder locking force is also removed, and a predetermined time has elapsed. It is also possible to adopt a structure that is automatically stored in the main body later. This powerful structure is effective even if you forget to store the engaging part 2.

[0023] FIG. 1 (c) does not have the engaging portion 2, and a communication portion that communicates with the vehicle body inside the main body 3. In the embodiment, a structure is employed in which the open / close button 10 is operated to communicate with the vehicle body side from the signal transmission unit 11 and to transmit information by the authentication operation to the vehicle body side. Examples of such communication means include infrared communication and radio wave communication. In addition, an authentication operation unit is provided outside the main body 3, and the effectiveness of the operation of the open / close button 10 is determined by recognizing the operation of the authentication operation unit. In the drawing, although an example in which a password input method by a password number operation unit _5a such as a rotary dial is adopted as the authentication method of the authentication operation unit is shown, the present invention is not limited to this. Similarly to the above, it is also possible to adopt a fingerprint recognition method of the user by the fingerprint recognition unit 5b described later.

FIG. 2 (a) is a plan view showing an example of another protruding mechanism in the double key structure 1 that works on the first embodiment. As the protruding mechanism, FIG. This shows a case where a mechanism in which the engaging portion 2 protrudes by recognizing this by the fingerprint recognition portion 5b is shown. The fingerprint recognition unit 5b includes a fingerprint reading unit that collects a fingerprint image using an image sensor, and a comparison determination unit that analyzes the collected fingerprint image and compares it with a stored fingerprint image. Based on the analysis result, it is determined whether or not the force protrudes from the engaging portion 2. As such an image sensor, a general electrostatic capacitance type semiconductor sensor used for biometric authentication (biometric authentication), a direct reading method for scattered light in a finger, and the like can be considered.

[0025] FIG. 2 (b) adopts a mode in which the double key structure 1 that works on the first embodiment communicates with the vehicle body by infrared communication or the like and transmits information by the authentication operation to the vehicle body side. It is a top view which shows the Example of a case. The user is recognized by recognizing the user's fingerprint by the fingerprint recognition unit 5b, and the operation of the open / close button 10 is judged. The fingerprint recognition unit 5b is the same as described above.

FIG. 3 is a perspective view showing a second embodiment of the double key structure 1 according to the present invention. In other words, a key container 3b to which a key is attached, and the key container 3b is provided with a storage part 4 in which the key can be stored, and the engaging part 2 of the key K is locked by performing a predetermined authentication operation. It has a structure with a protruding mechanism for protruding from the container 3b. The key K usually has a locking hole 8 and the handle width is larger than the engagement width. Therefore, the key K is used to fix the existing key K to the storage section 4 of the main body. Is fixed as shown in the figure. The fixing tool 9 can be fixed by screwing so that it can correspond to the shape and positional relationship of the existing locking holes 8 of the key, Condensation on both sides can be considered.

[0027] When the key fixed by the fixing tool 9 is subjected to a predetermined authentication operation, the engaging portion 2 protrudes from the key container 3b by the protruding mechanism. Note that the above-described mechanism is employed for the projecting mechanism that makes use of force.

[0028] The main body 3b has a storage portion 4 that can store the engaging portion 2, and is preferably made of a light material that cannot be easily broken or melted. Therefore, it is conceivable to use a high-strength resin, for example, a composite material using reinforced fiber, or a light alloy having a high specific strength, for example, an aluminum alloy or a titanium alloy. Also, it is ideal to have a structure that cannot be disassembled so that it cannot be removed by disassembling so that it cannot be taken out, or that it cannot be disassembled without a dedicated tool. Is.

[0029] Next, the usage mode of the double key structure 1 that is effective in the present invention having the above-described configuration power will be described in order based on the drawings.

[0030] First, as a preparation stage, if necessary, a storage operation such as a password or a fingerprint necessary for the authentication operation, or an existing key K is set in the key container 3b. When using the open / close lock, first, an authentication operation in the authentication operation unit is performed. For example, when the authentication method is an electronic password input method using the password operation unit 5a, a multi-digit number or alphabet is input from the password operation unit 5a by operating a button. If the authentication method is a mechanical PIN code input method using the PIN number operation unit 5a, the dial is rotated and the dials are arranged on a predetermined number. When the authentication method is a fingerprint recognition method by the fingerprint recognition unit 5b, the fingerprint of the user is brought into contact with the fingerprint authentication unit 5b. After performing such an authentication operation, by operating the protruding button 6, the force for causing the engaging portion 2 to protrude, or the operating of the open / close button 10, enables the use. When the engagement portion fixing device 7 is adopted in the case of a car key or the like, the engagement portion fixing device 7 is operated by considering the safety due to malfunction or the like. Lock 2 so that 2 is not stored in the main body 3a or the key container 3b.

[0031] After use, the engaging portion 2 can be stored in the main body 3a or the key container 3b and carried by a predetermined button operation or the like. After use, for example, when the automobile key is removed from the cylinder lock for starting the engine, the engaging portion 2 is removed from the cylinder locking force. If the structure is such that it is automatically stored in the main body 3 after several tens of seconds, the engaging portion 2 is automatically stored in the main body 3 without performing this operation. It will be.

Industrial applicability

[0032] The double key structure 1 according to the present invention can be applied to keys for locking devices in a wide range of fields such as automobiles, building doors, and safes. It is expected to play a role in reducing the damage caused by building theft.
