Description

Fingerprint reader lock for chest of drawers}

The present invention relates to a drawer locking device for furniture having a multi-stage storage drawer, and more specifically, a knob assembly having a fingerprint recognition unit exposed to the front of the furniture and a fixing support positioned inside the furniture are combined with each other to Fingerprint recognition for drawers in which the eccentric driving pin of the knob assembly in the drawer is rotated through fingerprint detection by the fingerprint recognition unit, and locking and unlocking of the multi-stage drawers are made at once by rotating and elevating the driving pin. It's about the locking device.

Generally, a desk drawer for storing various items is provided at the bottom of an office or home desk or table, and various shapes, sizes and purposes such as office drawers for various documents and items, side tables, or home drawers such as closets. The chest of drawers with the is widely used.

This drawer is equipped with a relatively simple type of locking means for security, and is applied in the form of simultaneous locking and simultaneous unlocking of the entire multi-stage drawer rather than individual locking means for each drawer.

That is, a conventional lock means for a drawer is a conventional lock having a rotation shaft that rotates at a predetermined angle by a key operation, as in Registration Utility Model No. 20-0173791, and a hook installed on the rotation shaft to switch to the locked position and the unlocked position. Consisting of a lock body made of a sieve, and a lock fixing portion that holds the hook when the hook body is in the locked position and releases the lock when the hook body is in the unlocked position, and the hook body is a rotating arm part extending in the radial direction of the rotation axis And, it consists of a hook portion bent in a right angle direction from the rotating arm portion and a hook formed at the end thereof, and the lock fixing portion is installed on the inner wall surface of the furniture body, and consists of a hook of the hook portion and a circular pin to hold and release the hook. Door locks for furniture have been devised and registered.

In addition, in the case of Registration Patent No. 10-1659229, a furniture body with an accommodation space formed therein, and a plurality of drawers that are inserted into the furniture body in multiple stages, and a drawer protruding more than one side of the drawers. A locking member that is fixed to the drawers and extends vertically in the interior of the furniture, and a main shaft that moves up and down along the extension direction, and is fixed to the main shaft to prevent the movement of the locking member according to the vertical movement of the main shaft. A drawer safety locking device including a blocking member that restrains and a drawer cabinet having the same have been devised and registered.

In particular, by actively improving the existing structure in which only a simple locking function was granted, such as in the recent Patent Registration No. 10-1730417, a single drawer is pulled out even in a state of unlocking by key operation to collectively lock other drawers. Induction of locking with individual drawers configured so that a series of actions related to locking can be controlled more accurately and quickly, as well as preventing falling accidents caused by the center of gravity being concentrated forward. An optional fall prevention chest of drawers has been devised and registered.

In this way, in the case of the existing locker for drawers, it is configured to simultaneously lock and unlock the drawers composed of multiple stages, and the locking means is designed and prevented from invading or loss of the available space inside the drawer. It can be said that it is characteristic to apply.

However, the existing locker for drawers is composed of a key box and keys mounted on the furniture body, and there is a hassle to always carry the above keys, and when a large number of drawers must be managed or used. In addition to having to carry and store all of the above keys, as well as requiring separate markings with a similar key structure, there is a great deal of hassle in use.

In particular, small and light types of keys are likely to be easily lost, and if the key is lost or damage occurs, the above locking device cannot be unlocked. Therefore, it is inevitable to call a key expert or damage the locking device. It is uneconomical, and when the drawer is locked, it must be unlocked with a key, so it is very inconvenient, such as having to take the key to the location where the key is located or the key is stored, and a large number of people need security. In the case of using in common, it is extremely inconvenient for a large number of users to use it, such as each user has a separate key or has to borrow a key each time.

In addition, due to the characteristics of drawers where the importance of storage items is relatively low, the above locking device has a simple locking structure, so that the locking device can be forcibly damaged and unlocked by using tools other than the user, and sometimes similar types. Since it is impossible to keep the locked state continuously and stable, such as unlocking the locked state by using the key of, it has an irrationality that cannot be used at all for the purpose of storing expensive items or important items.

Korea Registered Utility Model 20-0173791 (Registered December 21, 1999) Korean Patent Registration 10-1659229 (Registered on September 13, 2016) Korean Patent Registration 10-1730417 (registered on April 20, 2017)

The present invention improves the above-described problem, and combines a knob assembly having a fingerprint recognition unit exposed to the front of the furniture and a fixed support positioned inside the furniture to detect the knob assembly through the fingerprint recognition unit. The fixed state between the lock and the fixed support is released, and the eccentric driving pin of the knob assembly in the drawer is rotated and lifted by artificially rotating the unlocked knob assembly. By configuring the unlock to take place at a time,

It is an object of the present invention to provide a fingerprint recognition lock device for a drawer so that a drawer can be unlocked or locked easily through the user's own fingerprint and the registered user's fingerprint without carrying and storing the key as in the past. will be.

The present invention for achieving the above object is, an expansion flange portion having an assembly hole is formed on one side of a fixing support that is inserted outwardly through the drawer from the inside of the drawer, and a knob assembly having a fingerprint recognition pad exposed on the front side thereof. The rotating shaft part protruding to one side is inserted into the inside of the fixed support,

A fixing holder to which the fingerprint recognition pad and the identification circuit board are coupled is inserted and fixed into the knob assembly, and a rechargeable battery, a driving circuit board, and an actuator located in the rotation shaft are sequentially inserted into one side of the circuit board. At the end of the actuator, an eccentric rotation protrusion is formed protruding, and the eccentric rotation protrusion is inserted into a locking groove formed in a protruding pin inserted through a through hole formed in the rotation shaft, and the end of the rotation shaft protruding through the fixed support is to one side. A driving coupling member having an eccentric protruding driving pin is fixedly formed, and a locking hole is formed in the fixing support so as to coincide with the through hole of the rotating shaft portion,

The raised pin is inserted into the through hole and the locking hole at the same time, so that the knob assembly is non-rotated from the fixed support, and when the registered fingerprint is detected by the fingerprint recognition pad, the eccentric rotation rotates through the operation of the actuator. As the protrusion causes the protrusion pin to descend and is separated from the locking hole, manual rotation of the knob assembly is made, and the driving pin lifts and lowers the intermittent operation rod coupled to the inner side of the drawer so as to be elevated. Is to unlock or allow the locked state to be established.

The present invention enables simultaneous locking and unlocking of the drawers of the drawer cabinet quickly and effectively through the user's own fingerprint recognition without carrying or storing the unlocking tools such as keys, so it is very easy to use and efficient use. Since multiple fingerprint registration methods can be applied, it is possible to register other users in addition to the user himself, so that designated users can freely use the common drawer, and the cost is increased compared to the existing drawer lock because it has a relatively simple configuration. It is very economical because it is not large, and it can be used continuously without replacing the battery through periodic charging of the built-in rechargeable battery, so it has very excellent efficiency.

First, the present invention is a tube-shaped fixing support 200 that is inserted outwardly through the drawer from the inside of the drawer 300, and is exposed to the front of the drawer 300 to be inserted and coupled to the fixing support 200. Consisting of a knob assembly 100, an expansion flange portion 202 having an assembly hole 201 is formed on one side of the fixing support 200 so that the expansion flange portion 202 is in close contact with the inner surface of the drawer 300 In this state, the fixing support 200 can be firmly attached and fixed to the inside of the drawer 300 using the assembly hole 201.

In addition, the knob assembly 100 is a fingerprint recognition pad 110 is exposed on the front, one side of the knob assembly 100 is a rotating shaft portion 101 to be inserted into the inside of the fixed support 200 Is formed to protrude long, so that the rotation shaft portion 101 of the knob assembly 100 is inserted and coupled to the fixed support 200, the knob assembly 100 is gripped and the cabinet 300 is manually It is possible to arbitrarily rotate the knob assembly 100 from the front.

Particularly, a fixed holder 130 to which the fingerprint recognition pad 110 and the recognition circuit board 120 are coupled is inserted and fixed inside the knob assembly 100, and the fingerprint recognition pad 110 and the recognition circuit board 120 determines whether the registered fingerprint is the same as the registered fingerprint and stores the user's fingerprint to be registered, and the fingerprint recognition pad 110 and the identification circuit board 120 are the fixed holder 130 After inserting the fixing holder 130 from the front of the knob assembly 100 to the inside in a fixed state, inserting a separate fastening bolt from the rear surface of the knob assembly 100 and screwing into the fixing holder 130 By being configured to be coupled, the fixed holder 130 is rigidly fixed to the knob assembly 100 and the fingerprint recognition pad 110 and the identification circuit board 120 in the fixed holder 130 are maintained in a stable and close fixed state. It can be.

In addition, before the fixing holder 130 is coupled, the rechargeable battery 140 and the driving circuit board 150 are inserted into the knob assembly 100, and the rotary shaft portion 101 on one side of the knob assembly 100 A separate actuator 160 is inserted inside.

At this time, the charging terminal (not shown in the drawing) formed on the driving circuit board 150 is exposed from the knob assembly 100 so that power is applied from the outside through a charging cable, and the rechargeable battery 140 is repeatedly When a fingerprint registered by the fingerprint recognition pad 110 and the recognition circuit board 120 is detected, the actuator 160 may be charged through the rechargeable battery 140 and the driving circuit board 150. It operates automatically by receiving power.

Then, one side of the actuator 160 is operated so that the eccentric rotation protrusion 161 protruding from the end is rotated, and one end of the eccentric rotation protrusion 161 is inserted into a separate protruding pin 170 As such, the projection pin 170 is inserted from the outside through the through hole 102 formed in the rotation shaft portion 101 into the inner side of the rotation shaft portion 101, and a locking groove ( Since 171 is formed, the eccentric rotation protrusion 161 can be inserted.

Therefore, when one side of the actuator 160 is rotated by driving, the eccentric rotation protrusion 161 is also rotated so that the eccentric rotation protrusion 161 slips in the locking groove 171 of the protruding pin 170. At the same time, the projection pin 170 is in a linear motion up and down, and the tip of the projection pin 170 repeatedly moves from the through hole 102 of the rotation shaft portion 101 as the projection pin 170 moves up and down. Up and down haunting operation is performed.

In particular, as the spring 180 is elastically held on the lower side of the protruding pin 170, the protruding pin 170 is configured to be lifted more elastically.

Subsequently, a square protrusion 103 and a screw coupling part 104 are sequentially formed at the end of the rotation shaft 101 so that only the square protrusion 103 and the screw coupling part 104 protrude through the fixed support 200 The square protrusion 103 is coupled with a separate drive coupling unit 190, and then the washer 194 and the fixing nut 195 are sequentially coupled to the screw coupling unit 104 to be fixed. .

At this time, a fastening hole 193 having an 8-way groove 192 is formed in the center of the driving coupler 190, and one side of the driving coupler 190 is for coupling the driving pin 191 The deflection protrusion 196 is formed, and the assembly position for the driving pin 191 can be adjusted according to the coupling direction of the fastening hole 193 to the square protrusion 103 using the 8-way groove 192 It is configured to do. Therefore, it is possible to adjust the initial assembly height of the driving pin 191 by the coupling direction of the driving coupling unit 190 to the square protrusion 103.

That is, it is applied to drawers of various shapes and sizes by adjusting the initial assembly height of the driving pins 191, and in the case of a small drawer cabinet that does not require a large amount of rotation of the driving pins 191 Alternatively, the initial assembly height of the driving pin 191 is variously changed according to the characteristics of the drawer to be applied, such as a large drawer in which the rotational descending amount of the driving pin 191 should be maximum, so that the rotational descending amount of the driving pin 191 is appropriate. You will be able to change and assemble.

Subsequently, a limiting protrusion 204 of a certain section to interfere with the deflection protrusion 196 of the driving coupling unit 190 is protruded on one side of the fixing support 200, and the deflection protrusion 196 The knob assembly 100 due to mutual interference between the deflection protrusion 196 and the limiting protrusion 204 when the knob assembly 100 including the drive coupling unit 190 rotates due to the limiting protrusion 204 located within the rotation radius. ), the rotation direction and rotation amount and rotation angle may be limited.

In particular, by forming a locking hole 203 to coincide with the through hole 102 of the rotating shaft portion 101 described above in the fixed support 200, a protruding pin protruding from the through hole 102 of the rotating shaft portion 101 (170) is to be inserted into the inside of the locking hole 203, but when the projection pin 170 is raised, it is located inside the locking hole 203 on the upper side of the projection pin 170, and the knob assembly ( A fixed state in which 100 cannot be rotated from the fixed support 200 will be produced, and when the protruding pin 170 descends, the protruding pin 170 is separated from the lower side of the locking hole 203 and the fixed support ( The rotation of the knob assembly 100 with respect to 200 can be made freely.

Therefore, when the fingerprint recognition lock device of the present invention touches the user's fingerprint registered on the central fingerprint recognition pad 110 of the knob assembly 100 located in front of the drawer 300 as shown in FIGS. 6 and 7 When the internal identification circuit board 120 determines whether or not the fingerprint is registered, and if the fingerprint is registered, the actuator 160 is rotated by supplying power to the actuator 160.

Subsequently, when the eccentric rotation protrusion 161 in an elevated state by the rotational operation of the actuator 160 is rotated in the downward direction, the protruding pin 170 coupled with the eccentric rotation protrusion 161 descends together. As the protruding pin 170 is separated from the assembly hole 201 of the fixing support 200, a free rotational state with respect to the knob assembly 100 is achieved.

Thus, when the user rotates in one direction while holding the knob assembly 100, the rotation shaft part 101 inserted into the fixed support 200 rotates together, and by the rotation of the rotation shaft part 101 The driving pin 191 of the driving coupler 190 located at one end of the fixed support 200 may also be rotated downward within a range that does not interfere with the limiting protrusion 204 of the fixed support 200.

Therefore, as shown in Fig. 8, the fingerprint recognition locking device of the present invention is fixedly installed on the drawer 300, and fixed with the knob assembly 100 while the driving pin 191 of the driving coupler 190 is located on the upper side. The support 200 is fixed to the protruding pin 170, and the driving pin 191 has a system located at the top of the intermittent operation table 310 vertically positioned on the side of each drawer 301 in the drawer 300. It is just assembling to be inserted on the zip pin 311.

Accordingly, when the driving pin 191 of the driving coupler 190 is in the initial raised state, the intermittent operation table 310 will also be in an elevated state, and the intermittent pin 312 protruding from one side of the intermittent operation table 310 In the case of, since it is located inside a lower locking groove (a symbol in the drawing is omitted) of each drawer 301, a locked state for each drawer 301 is achieved.

Here, the explanation of the operation of the intermittent operation table 310 and the locking pin 311 and the lower locking groove of the intermittent pin 312 and the drawer 301 is the same as that of the conventional key box and the elevating intermittent structure using a key. I will explain it clearly.

Therefore, in a state in which the driving pin 191 is located on the upper side and the protruding pin 170 protrudes upward, all of the drawers 301 are locked by the intermittent pin 312 by the rise of the intermittent operating table 310. It will remain in the state of being.

In such a state, when a user authorized to use, that is, a user whose fingerprint is registered, touches a finger on the fingerprint recognition pad 110 in the knob assembly 100 protruding toward the front of the drawer 300, the actuator automatically detects the fingerprint. 160 is a rotational operation, and the rotation shaft portion 101 and the fixed support 200 of the knob assembly 100 are unlocked from each other by the lowering protruding pin 170 by the rotational operation of the actuator 160. Will come true.

Therefore, the user grips the knob assembly 100 and rotates it manually, and the drive coupling unit 190 that was coupled to the square protrusion 103 of the rotating shaft portion 101 by the rotation of the knob assembly 100 The rotation of and downward rotation of the driving pin 191 occurs, and as the locking pin 311 of the intermittent operation table 310 that interferes with the driving pin 191 is lowered, the lowering of the intermittent operation table 310 is Of course, since the lower locking pin 312 is departed downward from the lower locking groove of the drawer 301, the locked state for all the drawers 301 can be quickly released.

Subsequently, in the case of attempting to recreate the locked state for the drawer 301, the knob assembly 100 in the rotated state is rotated in the reverse direction so that the driving pin 191 of the driving coupler 190 rotates upward again. The intermittent operation table 310 is raised, and the intermittent pin 312 of the intermittent operation table 310 is again positioned in the lower locking groove of the drawer 301 to lock all the drawers 301, and the fingerprint The actuator 160 is operated by a locking signal that lightly touches the recognition pad 110 to raise the lowered protruding pin 170 again, and the rotation shaft portion 101 and the fixed support 200 of the knob assembly 100 If) are fixed to each other, the locked state is established for the locking device.

Therefore, the fingerprint recognition lock device for a drawer of the present invention locks and unlocks the drawer of the drawer at the same time by using a registered user's fingerprint. It is excellent in convenience in use and it is necessary to carry or store a separate key, etc. It is not very efficient.

The configurations shown in the embodiments and drawings as described above are only the most preferred embodiment of the present invention, and do not represent all the technical spirit of the present invention, so various equivalents and modifications that can replace them It should be understood that there may be examples.
