Description

{Locker room having unlocking ability for master}

[0001] The present invention relates to an article storage box, and more particularly, it relates to an article storage box capable of easily locking and unlocking a door by adopting a dialing method in which a user can easily change a password, It is convenient to manage the storage box. Especially, in case that the previous user has forgotten the password or can not be contacted for a long time, it is possible to check the password set in the manager's storage box and open the door as needed. To an unlocking function for unloading a master.

In addition to the office furniture, various types of locks are installed in lockers installed in public places such as schools, libraries, waiting rooms, gyms, and saunas.

A mechanical lock device and a digital lock device are installed in the lock device of the present invention. Recently, a number of digital lock devices have been proposed to solve the inconvenience of having a key.

However, in the state where the battery of the digital lock device is discharged, the locking device is unlocked only when the power source is manually supplied to the external terminal. In such a case, if the battery is discharged in this manner, the temporary battery can not be prepared quickly, It took a long time to use it. In addition, when it is applied to a door of a storage box installed in a public place in large quantities, there are a lot of inconveniences for administrators because there are many inquiries about troubles and usage methods as well as user inconvenience.

Due to such a problem of the digital locking device, a mechanical locking device has been actively used as a locking device for a common storage device. In the case of mechanical locks, which are commonly used in common warehouses, dial-type locks are widely used, which can solve the inconvenience that individual users have to carry with them each time.

Such a dial (number wheel) type locking device is characterized in that a plurality of number wheels are stacked on an axis so that when the user rotates the respective number wheels and all of them match the predetermined password, the locked state is released and the door can be opened There have been proposed various types of dial locking devices such as Korean Patent Laid-open Nos. 2006-0100502, 2005-0113005, 2008-0072525, Korean Utility Model Registration No. 0349788, and 0358480. Such a dial type locking device allows the user to confirm the setting of the password in the initial unlocked state, to close the door after closing the door after storing the article, and then to rotate the dial (number wheel) at random to maintain the locked state.

However, there is a case where such a dial type locking device is provided with a separate means for confirming when a user forgets a password. This is because when a confirmation pin is inserted into a pin hole formed at one side of the locking device, , The confirmation pin is inserted into the pin receiving groove formed in the inner rotating body rotated together with the number wheel at a specific position, so that the number wheel is fixed at the corresponding password position, The password can be confirmed. However, if the user who knows the password can not be contacted for a long period of time because the lock can not be contacted for a long time, the lock or the door may be damaged And the like.

On the other hand, the dial type locking device has means for resetting the user's password, which is also possible in the unlocked state of the locking device, in which each inner wheel rotated with each number wheel In this state, the number wheel is rotated, the desired number is set, and the inner wheel is re-bound to each number wheel.

In order to perform the password initial setting and resetting function, the dial type locking device applied to the common use locker is configured such that the locking device is basically enabled only when the locking device is unlocked. The locking device or the door must be broken to open the storage box. In particular, the lock device which is detached from the door and is detached from the door can not be provided with any means for releasing the locking device there was.

In addition, in order to apply various functions such as locking, unlocking, and password change to a single locking device as described above, many internal parts are structured to be complicated and coarse connected, so that the volume of the locking device tends to increase considerably. As a result, this increases the manufacturing cost of the locking device for a common use locker, and the durability of the locking device is structurally inevitably degraded, so that the dial operation is not elaborate and the safety is inevitably lacking.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an apparatus and a method for locking and unlocking a user, If the old user does not remember the password or does not contact the user for a long time and needs to open the door for the next user while the password is set, the administrator immediately releases the lock and the password The present invention also provides a storage box having a lock function for a master which can be reset.

Another object of the present invention is to provide an article storage box having an unlocking function for a master having an excellent durability of a locking device by maintaining a simple and structurally simple connection relationship with a limited space of a main body of a small- .

According to an aspect of the present invention, there is provided an electronic device including a main body, a main body having a main body, a latch for maintaining a locked state or an unlocked state by insertion of the one end into the main body and moving in the axial direction, And a door locking device formed of a plurality of number wheels which are engaged with the outer circumferential surfaces of the respective swivel rotors to rotate the swivel,

FIG. 10 is a cross-sectional view illustrating a process of locking and unlocking a locking device using a user-operating unit, FIG. 11 is a cross-sectional view illustrating a password resetting process of a locking device using a user- FIG. 8 is an exemplary cross-sectional view illustrating a process of unlocking a locking device using an operation part for a master;

Referring to FIG. 10, the lock setting of the locking device by the user is performed when the latch 2 is in the locked state, that is, when one free end is closely fitted to the receiving groove formed in the main body 1 The engagement protrusion 210 formed on the other insertion end 21 of the latch 2 passes through the through groove 321 formed in the sleeve protrusion 32 of the rotation table 3, When the user rotates the number wheel 4 arbitrarily in a state in which the engaging jaw 210 of the wheel 2 has passed through the through groove 321 of the rotating table 3 and the engaging arm portion 41 formed at the upper end of the inner surface of the number wheel 4 And the engaging jaw 210 of the latch 2 is engaged with the sleeve jaw 32 of the rotating table 3 so that the latch 2 Is maintained in the door locking state in which it does not come off the main body 1. [

When the user who knows the password locks the number wheel 4 by rotating the number wheel 4, the locking arm 41 formed at the upper end of the inner circumference of the number wheel 4 The through hole 321 formed in the sleeve protrusion 32 of the swivel base 3 is connected to the insertion end 21 of the swivel 2 The latch 2 is positioned in parallel with the axial direction of the latching jaw 210 so that the latch 2 can be separated from the main body 1, thereby maintaining the unlocked state of the door.

11, when the user wishes to change the password of the lock device, the user can change the password in the unlocked state. In the unlocked state, the user inserts the lock device 2 into the one insertion end 21 so that the engaging protrusions 210 of the insertion end portion 21 are disposed at positions displaced from the through grooves 321 formed in the sleeve tucks 32 of the rotating table 3. [ In this state, when the latch 2 is pressed in the axial direction, the latching jaw 210 of the insertion end portion 21 presses the upper surface of the sleeve jaw 32 of the rotation table 3 downward. The swivel base 3, which is pushed downward by the latching jaws 210 of the latch 2, is moved downward to overcome the elasticity of the support spring 35 provided at the lower end. The engaging portion 31 formed on the outer circumferential surface of the turntable 3 is separated from the engaging arm portion 41 formed on the upper end of the inner circumferential surface of the number wheel 4, And the free wheel 40 extends in the free rotation extension 42 formed at the lower end of the inner circumferential surface of the wheel 4 so that the rotation wheel 3 and the number wheel 4 maintain their power transmission disengaged from each other. In this way, the number wheel 4 which makes the power transmission from the rotation table 3 is released, and the user re-sets the new password. When the resetting of the passwords for the plurality of number wheels 4 is completed, the user removes the external force pressing the latch 2, and the rotation table 3, which is elastically supported by the support spring 35 in cooperation with the removal, The engaging male portion 31 formed on the outer circumferential surface of the number wheel 4 is further engaged with the engaging arm portion 41 formed on the upper end of the inner circumferential surface of the number wheel 4 so that the rotating wheel 3 and the number wheel 4 are held in a state of being constrained to each other The position where the engaging protrusions 210 formed on the insertion end 21 of the latch 2 and the through grooves 321 of the rotating table 3 are aligned in the axial direction coincides with the reset passwords of the number wheel 4 As shown in FIG.

Meanwhile, if the user can not open the storage box because the user has forgotten the password set by the user in a state where the locking device for the storage box using the user, the unlocking process, and the password changing process are free, It is necessary for the master (administrator) to open the storage box of the owner urgently such that the next user is not able to use the storage box, and in such a case, the master key is used to lock the storage box regardless of the set password. (000,111) or to change the password easily. [0154] In addition,

12, the master (master) rotates the key bundle 5 using the master key in the door lock setting state, and rotates the engaging projections 52 The rotation cams 6 on which the engagement grooves 61 are supported are rotated in cooperation with each other. At this time, the rotation cam 6, which has supported the one support end 81 of the movable block 8 by the first support surface 62, rotates while the second support surface 62 having a larger radius of rotation than the first support surface 62 And supports the supporting end 81 of the moving block 8 through the surface 63. [ The moving block 8 which is in close contact with the second supporting surface 63 of the rotating cam 6 overcomes the elastic force of the return spring 82 and slides toward the rotating table 3 on the opposite side The sensing pin 9 which is elastically protruded from the simultaneous moving block 8 by the pressing spring 92 protrudes from the pin guide hole 8a formed in the main body 1 and elastically deforms the outer peripheral surface of the rotating table 3 And pressurized. The plurality of sensing pins 9 rotate the respective number wheels 4 in an arbitrary direction in a state in which the outer circumferential surfaces of the rotating tables 3 are elastically pressed. When the number wheel 4 is rotated in this manner, the rotation table 3 rotates in conjunction with the number wheel 4, and at this time, the rotation table 3 rotates the pin receiving grooves (not shown) formed in the upper end The end of the sensing pin 9 is engaged with the pin 33 and the rotation is blocked so that the pin receiving groove 33 of the rotating table 3 is aligned with the through hole 321 of the sleeve jaw 32 in the axial direction The number wheel 4 connected to the rotation table 3 maintains the state in which the rotation of the number wheel 4 is blocked from the set password. It is possible to easily find the point at which the pin receiving groove 33 of the rotating table 3 is hooked to the detecting pin 9 by rotating each of the number wheels 4 so that the password of the number wheel 4 can be naturally found . When the number wheel 4 is naturally set according to the thus set password, the master rotates the key bundle 5 and the rotation cam 6 again using the master key so as to move the rotation block 3 from the rotation block 3 to the moving block 8, And the detection pin 9 and moves the insertion end 21 of the latch 2 to release the lock. Of course, the master can reset the password or reset (000, 111), as described above, in a state in which the lock is unlocked, thereby maintaining the available state for the next user.
