With the handle 111 correctly positioned in the set position, the positioning pin is positioned to fit the positioning groove. The positioning pin may be provided with an elastic force to maintain the fit in the positioning groove.

The key recognition unit 140 may include a plurality of recognition bars 1410, a recognition bar moving unit, at least one pattern plate 1470, and a rotational force control unit 1480.

The recognition bars 1410 are arranged so that each lower end portion corresponds to the through pattern 12 and the first and second non-through patterns 13 and 14 of the through card key 10, respectively. For example, when the through patterns 12 and the first and second non-through patterns 13 and 14 are combined and arranged in two rows in the longitudinal direction of the through card key 10, the recognition bars 1410 are also arranged in two rows. Each lower end portion is arranged to correspond to the through pattern 12 and the first and second non-through patterns 13 and 14.

Each lower end of the recognition bars 1410 has a size that can be inserted into the through portion 12a of the through pattern 12 and the second through portion 14a of the second non-through pattern 14. In addition, the recognition bars 1410 are formed with protruding pins 1411 on each side thereof. The protruding pins 1411 of the recognition bars 1410 protrude so that they can be inserted into the first, second and third pattern holes 1471, 1472 and 1473 of the pattern plate 1470, respectively.

The recognition bar moving unit is for raising and lowering the recognition bars 1410 independently. The recognition bar moving unit may include a recognition bar guide unit, the recognition bar elastic members 1440, the movable frame 1450, and the movable frame moving unit.

The recognition bar guide unit guides the lifting of the recognition bars 1410. The recognition bar guide part may include a lower frame 1431, a vertical frame 1432, and an upper frame 1434. The lower frame 1431 guides the lifting through the lower ends of the recognition bars 1410. The vertical frame 1432 projects vertically from the lower frame 1431 between the pattern plate 1470 and the recognition bars 1410. In the vertical frame 1432, guide holes 1433 are formed to respectively support the protruding pins 1411 of the recognition bars 1410 so as to be liftable. The upper frame 1434 is coupled with the vertical frame 1432 on the upper side of the lower frame 1431, and guides the upper and lower frames through the upper ends of the recognition bars 1410.

Recognition bar elastic members 1440 are installed on each upper side of the protruding pins 1411 to apply an elastic force in the direction of lowering the recognition bars 1410. For example, the recognition bar elastic members 1440 may be formed of compression coil springs, respectively. In addition, each recognition bar elastic member 1440 is supported by a lower end of the upper frame 1434 and the lower end of the upper side of the protruding pin 1411 while being fitted to the upper end of the recognition bar 1410. By being supported, an elastic force can be applied in a direction to lower the recognition bar 1410.

The movable frame 1450 is disposed to correspond to each lower side of the protruding pins 1411 to elevate the recognition bars 1410 as the lifting operation is performed. That is, in the process in which the movable frame 1450 moves up to the maximum, the recognition bars 1410 are raised as the protruding pins 1411 are all supported and raised by the movable frame 1450. At this time, a compressive force is applied to the recognition bar elastic members 1440, and thus the recognition bars 1410 are in a state of receiving an elastic force in a downward direction.

In this state, when the movable frame 1450 moves downward to the maximum, the recognition bars 1410 are lowered by the restoring force of the elastic members 1440 for the recognition bars. At this time, the recognition bars of the recognition bars 1410 corresponding to the through patterns 12 are lowered until they are inserted into the through parts 12a. The recognition bars corresponding to the first non-hole pattern 13 among the recognition bars 1410 are lowered until they are in contact with the first non-hole parts 13a. The recognition bars corresponding to the second non-hole patterns 14 of the recognition bars 1410 are lowered until they are inserted into and contacted with the second non-hole portions 14a.

The movable frame moving part raises and lowers the movable frame 1450 according to the rotation operation of the handle part 110. The movable frame moving part may include a rotating shaft 1541 and a pair of cams 1462. The rotating shaft 1462 is coupled to the rotation center of the handle 110 and rotates according to the rotation operation of the handle 110. And, the rotating shaft 1541 extends toward the unlocking platform 120. A pair of cams 1462 are provided on the rotating shaft 1541 to elevate the movable frame 1450 while rotating with the rotating shaft 1462.

For example, the cams 1462 are disposed adjacent to both ends of the rotating shaft 1541. In addition, the movable frame 1450 may include a first movable portion 1451 and a pair of second movable portions 1452 in contact with the upper surfaces of the cams 1462, which are disposed to correspond to the lower sides of the protruding pins 1411. It may be made in a connected form. The second movable parts 1452 may be elevated in accordance with the rotation operation of the cams 1462 by maintaining the state in contact with the cams 1462 by the recognition bar elastic members 1440. The cams 1462 raise the movable frame 1450 to the maximum when the portion furthest from the center moves to the top dead center, and lower the movable frame 1450 to the maximum when the portions closest to the center move to the bottom dead center, respectively. do.

First, second, and third pattern holes 1471, 1472, and 1473 are formed in the pattern plate 1470. When the through patterns 12 and the first and second non-through patterns 13 and 14 are combined and arranged in two rows in the longitudinal direction of the through card key 10, two pattern plates 1470 are provided in each row. Correspondingly arranged. The pattern plates 1470 are provided with an elastic force toward the handle part 110 by the elastic member 1476 for the pattern plate.

The first, second, and third pattern holes 1471, 1472, and 1473 have a height of the protruding pins 1411 when the recognition bars 1410 descend, and the through-hole pattern 12 and the first and second non-hole patterns 13. Only when it is positioned in accordance with 14 and the recognition is successful, the pattern plates 1470 guide the protruding pins 1411 to be slidable in the direction of the handle portion 110 by the elastic member 1476 for the pattern plate, respectively.

For example, as shown in FIGS. 5 to 7, the first pattern hole 1471 is connected to the lower end of the first vertical long hole 1471a and the first vertical long hole 1471a to be away from the handle part 110. It may be composed of a first horizontal long hole (1471b) formed. The first horizontal long hole 1471b is positioned to receive the protruding pin 1411 in a state in which a recognition bar corresponding to the through pattern 12 of the recognition bars 1410 is inserted into the through portion 12a, thereby forming the pattern plate 1470. ) Slides toward the handle 110.

The second pattern hole 1472 may be configured as a second horizontal long hole 1472b connected to an upper end of the second vertical long hole 1472a and the second vertical long hole 1472a and formed in a direction away from the handle part 110. . The second horizontal long hole 1472b is positioned to receive the protruding pin 1411 in a state in which a recognition bar corresponding to the first non-hole pattern 13 of the recognition bars 1410 is in contact with the first non-hole part 13a. The pattern plate 1470 slides toward the handle 110.

In addition, the third pattern hole 1473 may be configured as a third horizontal long hole 1473b connected to an upper end of the third vertical long hole 1473a and the third vertical long hole 1473a and formed in a direction away from the handle part 110. Can be. The third horizontal long hole 1473b may accommodate the protruding pin 1411 in a state in which a recognition bar corresponding to the second non-hole pattern 14 of the recognition bars 1410 is inserted into and contacted with the second non-hole portion 14a. By being positioned, the pattern plate 1470 can be slidably moved toward the handle portion 110.

Therefore, as shown in FIG. 5, when the recognition bars 1410 are raised and then lowered as shown in FIG. 6, the through portion 12a and the second non-through portion 14a of the recognition bars 1410 are raised. And only the protruding pins 1411 of those corresponding to the lower side are positioned along the first and third vertical long holes 1471a and 1473a to be received in the first and third horizontal long holes 1471b and 1473b, respectively. The protruding pin 1411 of the one corresponding to 13a is positioned to be received in the second horizontal long hole 1472b without descending along the second vertical long hole 1472a. Then, as shown in FIG. 7, the pattern plate 1470 is slidably moved toward the handle part 110 by the elastic member 1476 for the pattern plate.

The rotational force intermittent part 1480 transmits the rotational force of the handle 110 to the unlocking platform 120 while the pattern plates 1470 slide in the direction of the handle 110.

Referring to FIG. 8, the handle 110 includes a handle 111 having a drive gear 112 formed along an inner circumferential surface thereof, and a driven member coupled to the rotation shaft 1541 on the same plane as the drive gear 112. The gear 113 and the planetary gear 114 meshed with the drive gear 112 and the driven gear 113 between the drive gear 112 and the driven gear 113. When the knob 111 is rotated, the planetary gear 114 meshed with the drive gear 112 rotates to rotate the driven gear 113. Accordingly, since the rotary shaft 1541 can rotate, the rotational force of the handle 111 can be transmitted to the rotary shaft 1541.

The rotational force intermittent part 1480 may include a driven block 1441, a support block 1462, and a drive block 1483. Follower block (1481) is a pair of engaging projections (1481a) formed on a surface facing the handle portion 110 at regular intervals, the unlocking platform 120 is coupled to the opposite surface. When the driven block 1441 rotates, the unlocking platform 120 rotates together.

The support block 1462 is coupled to the pattern plates 1470 and slides together, and rotatably supports the driven block 1441. The drive block 1483 is provided at the end of the rotary shaft 1541 and rotates with the rotary shaft 1541. The driving block 1483 includes a pair of locking grooves 1483a that engage with the locking protrusions 1441a while the pattern plate 1470 slides toward the handle 110.

Referring to Figures 9 to 11, the operation of the rotational force interruption unit 1480 described above is as follows. As shown in FIG. 9, even when the through hole card key 10 is inserted into the key inserting unit 130 or when the recognition of the through card key 10 fails, the drive block is rotated even when the handle 110 is rotated. Since the 1483 and the driven block 1441 are spaced apart from each other, the rotational force of the driving block 1483 is not transmitted to the driven block 1148.

Upon successful recognition of the hole card key 10, as shown in FIG. 10, the pattern plates 1470 are moved in the direction of the handle 110, so that the support block 1462 is moved to the pattern plate 1470. The locking projections 1441a of the driven block 1441 are respectively inserted into the locking grooves 1483a of the driving block 1483 while moving together with each other. In this state, when the handle 110 is rotated, as shown in Figure 11, the driven block (1481) while rotating the unlocking platform 120 is rotated. The rotational force of the unlocking platform 120 may act to release the locking state of the cladding bundle.

The key return actuator 150 may include a pushing pin 151 and a pushing protrusion 152. The pushing pin 151 protrudes from the drive block 1483 toward the support block 1441. The pushing protrusion 152 is pushed by the pushing pin 151 to return the pattern plate 1470 to its original position as the handle 110 is continuously rotated in the same direction while the locking state of the clamping bundle is released. To protrude from the support block 1462.

Referring to the operation of the above-described key return operation unit 150 as follows. With the locking state of the clasp bundle released, when the handle 110 is further rotated in the same direction, as shown in FIG. 12, the pushing pin 151 moves while pushing over the protruding surface of the pushing protrusion 152. Together with the protrusion 152, the support block 1462 is pushed away from the handle 110. As a result, the pattern plates 1470 are returned to their original positions and at the same time, the driving block 1483 and the driven block 1441 are spaced from each other.

In this state, when the handle 110 is continuously rotated in the same direction, the pushing pin 151 moves along the protruding surface of the pushing protrusion 152 while being spaced apart between the driving block 1483 and the driven block 1148. In this state, the movable frame 1450 is raised to the maximum by the cams 1462. In this process, the recognition bars 1410 are raised to separate all from the through card key 10 by the movable frame 1450. Therefore, the user can recover the through-hole card key 10 from the card insertion unit 130.

On the other hand, in the case of including the RFID tag 15 having the access identification information embedded in the through-hole card key 10, although not shown, the locking release device 100 may further include an RFID authenticator. In a state in which the recognition is successful by the key recognition unit 140, the RFID authenticator reads the access identification information embedded in the RFID tag 15, and when the authentication is successful, locks the bundle of locks together with the key recognition unit 140. It acts to release. For example, the RFID authenticator may be configured to restrain the slide movement of the pattern plates 1470 and then release the restraint on the pattern plates 1470 upon successful authentication.

Therefore, only when both of the through patterns 12 and the first and second non-through patterns 13 and 14 of the through card key 10 are recognized successfully and the RFID tag 15 is authenticated successfully, the door is locked. By allowing the state to be released, security can be further enhanced.

An operation example in which the locked state is released by the locking release device 100 having the above-described configuration will be described below.

First, after the hole card key 10 is inserted into the key insertion unit 130 of the locking release device 100, the handle 111 is rotated to rotate the rotating shaft 1541. Then, the cam 1462 which has raised the movable frame 1450 to the maximum rotates and lowers the movable frame 1450. Then, the recognition bars 1410 are lowered by the elastic members 1440 for the recognition bars, respectively. When the movable frame 1450 is maximally lowered, the recognition bars corresponding to the through patterns 12 among the recognition bars 1410 are lowered until they are inserted into the through portions 12a, and the first non-through pattern 13 Recognition bars corresponding to) are lowered until contact with the first non-through part 13a, and recognition bars corresponding to the second non-perforation pattern 14 are inserted into and contacted with the second non-perforation part 14a. Descend.

At this time, the protruding pins 1411 of the recognition bars 1410 are accommodated in the first, 2.3 horizontal long holes 1471b, 1472b, and 1473b of the first, second, and third pattern holes 1471, 1472, and 1473. When positioned, the pattern plates 1470 are slid in the direction of the handle 111 by the elastic member 1476 for the pattern plate, respectively. Accordingly, the driven block 1441 moves to the driving block 1483 so that the locking protrusions 1441a of the Middle East block 1441 are inserted into the locking grooves 1483b of the driving block 1483. When the handle 111 is continuously rotated in the same direction, the unlocking platform 120 rotates while the driven block 1441 is engaged with the driving block 1483 and rotates. Therefore, the locked state of the clasp bundle is released by the unlocking platform 120.

Subsequently, when the handle 111 is continuously rotated in the same direction, the pattern plate 1470 is returned to its original position by the interaction of the pushing pin 151 and the pushing protrusion 152, and the driven block 1441 and the driving block are returned. 1483 are spaced apart. In addition, as the movable frame 1450 is maximally raised by the cams 1462, the recognition bars 1410 are raised to separate all from the through card key 10. Therefore, the user can recover the through-hole card key 10 from the card insertion unit 130.

If, due to the recognition failure, any one of the protruding pins 1411 of the recognition bars 1410, the first, 2.3 horizontal long hole (1471b) of the first, second, third pattern holes (1471) (1472) (1473) If it is not accommodated in (1472b) 1473b, the pattern plates 1470 are incapable of sliding. Accordingly, since the driven block 1441 and the driving block 1483 are kept spaced apart, the rotational force of the handle 111 is not transmitted to the unlocking platform 120 even when the handle 111 is rotated. As a result, the catches are kept locked.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation and that those skilled in the art will recognize that various modifications and equivalent arrangements may be made therein. It will be possible. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
