Description

TECHNICAL LOCK HAVING A FUNCTION OF AUTOMATIC LOCKING

The present invention relates to a locking device having an automatic locking function installed on the porch of an office or a house and used for crime prevention, and minimizes the lock box area by efficiently using a limited space of a lock box, and provides a solenoid device. It is possible to simultaneously operate the vandal latch and the locking latch at the same time, so that it is easy to use and separates the driving arm of the vandal latch and the driving shaft of the driving arm so that it can run idle at the time of correction so that unnecessary load is not applied inside the lock box. However, this resulted in the effect of double locking, which also plays a role of corrective maintenance of the half moon clasp, thereby improving security and enhancing the convenience of use, thereby making it versatile and versatile.

In general, basic door locks are installed in home or office doors to prevent outsiders from entering.

A conventional door lock installed as described above has a disadvantage in that its security is not only simple in structure, but also easily released by those who have a certain level of common sense about the door lock.

Therefore, in the home or office, the electronic electronic door lock is additionally installed to increase security.

As described above, the digital door lock additionally installed and used in the door is that the locking latch is inserted into the groove of the door outer frame to keep the door locked and at the same time, the locking latch is released from the groove formed in the door frame to release the door locking state. It consists of two types:

That is, as shown in FIGS. 8A and 8B, the electric lock 10 is first externally (outdoor), and the external lock 13b is internally controlled (not shown) as the automatic locking switch 18 maintains the pressed state. Fixed so that it cannot be rotated by), that is, the internal control device is released when a predetermined electrical signal is received from the outside, and then the half handle 14 is locked by rotating the outer handle 13b in one direction. It is constructed on the principle of being inserted into the device box 11 and unlocked.

On the other hand, in the interior (indoor) there is a specification equipped with a one-operation opening mechanism (PANIC function) depending on the product, but once the illustrated product loosens the internal control device by turning the inner rotation knob (15) and press the inner knob (13a) to rotate It is organized in such a way as to be freed.

Figure 9 shows another example of the conventional electrostatic locking device when looking at the structure of the half moon clasp 23 is inserted into the lock box 21 by the rotation of the half moon clasp drive arm 22, but at the time of the locking clasp (24) is not operated to maintain the corrected state, when receiving an electrical signal from the outside, by moving the locking latch operating port 25 by the electromagnet to rotate by pressing the external handle (not shown in the opposite side of the drawing) half moon latch driving arm The locking latch driving arm 27 is rotated by the locking latch connecting piece 26 via the locking latch operating port 25, and the locking latch 24 is released.

On the other hand, since the electric lock 20 of FIG. 9 has a structure in which the locking latch 24 protrudes and is fixed as the door is closed and the automatic locking switch 28 is pressed, in some cases, the door is automatically closed before the door is closed. Since the switch 28 is pressed first and the locking latch 24 protrudes, a situation in which the door itself does not close is often caused, which causes damage to the electric well 200 itself and the door.

In addition, the manual lock switch 29 and the related mechanisms that can be switched manually and automatically in proximity to the automatic lock switch 28 are mounted inside the lock box 21, the lock latch return spring (30) And accordingly, the mechanism is also located on the upper side of the stand alone, resulting in excessively complex interior of the lock box 21 may cause frequent breakdowns, and in particular to install such structures requires a separate installation space Therefore, in the end, the size of the lock device box 21 should be large, and if the size is large in this way, there is a problem that lacks compatibility, which is larger than the general standard used.

In addition, the electrostatic well 20 of FIG. 9 is also used to connect the inner and outer handles with one shaft 31, and therefore, the one-operation opening mechanism cannot be mounted, and when the door is opened from the inside, the example of FIGS. 8A and 8B. As shown in the figure, the inside knob is turned and then the knob is rotated to open the door.

If we summarize the problems of the conventional electric well currently used,

First: In view of the domestic reality, which is sensitive to crime prevention measures and installs an auxiliary key separately from the main entrance key, only one locking clasp or half moon clasp acts as a corrective mechanism.

Second: In order to add multi-function to the limited space inside the lock box, the structure becomes complicated, which causes the failure.

Third: In order to accommodate the multifunction, the size of the lock box is too large than the general standard commonly used in Korea,

Fourth: In the case of the fixed handle type, there is a high risk of being released or breaking the lock box when forcibly opening.

Fifth: it was difficult to install the one-operation opening mechanism from the inside.

The present invention is configured to the same size as the lock device box generalized in the domestic in a predetermined size, but to efficiently use the space to accommodate the multi-function, to quickly escape to the outside in case of emergency such as fire and the user It is intended to provide a locking device that enables the one-operation opening function for convenience, and prevents unnecessary overloading due to the idling structure when the locking device is not damaged or released by physical shock or overload from the outside. .

At this time, the half moon clasp 132 connected to the pull plate 130 by the connecting piece 133 is pulled and pulled back into the lock box 111, while the interlocking arm located at the top by the rotation of the driving arm 121. By moving the rotation 171, the locking claw 172 is pulled by the interlocking arm 171 is pulled into the lock box 111 to retreat and at the same time the latch claws 182 formed in the locking mechanism 180 It is caught by the latching jaw 173 to stop the locking latch 172 inside the lock box 111.

On the other hand, the pressing projection 175 formed on the locking latch 172 is a state of pressing the key pressing plate pressing piece 113b formed on one side of the key pressing plate 113, as shown in Figure 4a, the key pressing plate 113 By pressing in conjunction with the pressing piece (112a) connected to the hinge shaft of 115 keeps the solenoid 112 to be continuously operated.

By rotating the outer handle 102b formed on the outer body 101b as described above, the vandal latch 132 and the locking latch 172 are simultaneously formed from the receiving groove (not shown) formed in the door frame (not shown) by one operation. By moving away, the door can be opened and closed.

As described above, when the half moon clasp 132 and the lock clasp 172 are pulled and pulled back into the lock box 111 to retreat, and the outer handle 102b is placed in the opened state, the order as shown in Figs. The stopper releasing tool 151 formed on the stopper shaft 152 is temporarily horizontally moved while the driving arm 121 rotates forward and moves the horizontal retaining piece 141 at the interval to move the horizontal retainer 140 toward the door frame. Keep it as

On the other hand, in the state where the stopper release mechanism 151 is horizontally maintained as described above, as shown in FIG. 6, the vandal latch 132 is caused by the impact of the return spring 134 formed between the vandal latch 132 and the pulling plate 130. ) And the pulling plate 130 is moved together by the connecting piece 133 of the vandal clasp 132 while being protruded toward the door frame, at this time, the horizontal holding portion 140 and horizontally maintained by the pulling plate 130 The stopper release tool 151 simultaneously moves to the front of the stopper 150.

As shown in FIG. 6A, the stopper releasing tool 151 moved to the front of the stopper 150 in an instant as described above is used to move the pulling plate 130 and the horizontal supporter 140 due to the impact of the return spring 134. By disengaging the stopper 150 from the release catcher 161, the release release piece 160 is formed on one side of the catch release release 160 while the release release release 160 is moved to the door frame side as shown in FIG. ) By touching the detent release piece 181 formed in the locking mechanism 180 holding the lock detent 172, the detent detent piece 182 is released from the detent jaw 173 and at the same time the spring 174 By protruding toward the door frame by) will be in the first locked state as shown in FIG.

In addition, as described above, while the locking latch 172 moves toward the door frame by the release of the locking hole 180 and the spring 174, the release protrusion 176 formed on the locking latch 172 as shown in FIG. 6C. The key press release piece 114 is touched to release the other end of the key press release piece 114 pushes the pressing piece 112a formed in the solenoid 112 to stop the operation of the solenoid 112. .

In addition, the key pressing plate 113 is connected to the pressing piece 112a by the hinge shaft 115, and the pressing piece 112a formed on the solenoid 112 is released and at the same time the key pressing piece 113a. As the formed key press plate 113 is also moved, the key press piece 113a is separated from the drive shaft connecting key 122 and at the same time the drive shaft connecting key 122 is separated from the key groove 120a so that the drive shaft 120 and the driving arm ( Since the driving shaft 120 is only idling, the driving shaft 120 and the driving arm 121 are separately operated.

On the other hand, look at the state of use of the present invention installed in a place frequented by a person, such as an office as follows.

First, the present invention should open the door. This is because it has been described above, so briefly described, the outer handle 102b formed on the outer body 101b when the password stored in operation by operating the button 104 installed on the outer body 101b is matched and the solenoid 112 is operated. By rotating the drive shaft 120 is driven to rotate the drive arm 121 to release the half moon clasp 132 and the locking clasp 172 in the locked state to release.

In the unlocked state as described above, the manual switching switch 190 formed at one side of the locking device box 111 is rotated so as to be downward toward the latch release mechanism 160.

Therefore, as shown in FIG. 7, when the manual automatic switching switch 190 faces downward, the latch release mechanism 160 is caught by the manual automatic switching switch 190 and no longer moves, thereby causing the locking latch 172 to be removed. By not contacting the clamp release piece 181 of the locking fasteners 180 which are being locked, it is not possible to release the locking holes 180, which is released by the rotational operation of the first driving arm 121, thereby locking the inside of the lock box 111. The locking latch 172 in the retracted state continues to be locked by the latching jaw 173 to the latch releasing piece 181 to remain in the unlocked state so that the rotation of the driving arm 121 is not affected at all. .

As described above, the locking latch 172 is held and stopped so that the half-clasp is driven by the driving arm 121 according to the rotation of the inner and outer handles 102a and 102b at frequent places when a person enters and exits. Only 132 can be operated to open and close the door.

Therefore, after the use of the manual automatic switching switch 190 as described above, by opening the door to the manual automatic switching switch 190 formed on one side of the lock box 111 to face upward in the original state. The door can be corrected using 172.

As described above, the present invention is a locking device having an automatic locking function which is installed in places such as homes or offices where access is not frequent, and used for crime prevention, and efficiently uses a limited space of the lock box. Minimize the area of the lock box, and enable the operation of opening the vandal latch and the locking latch at the same time by the solenoid device to ease the use and to separate the driving arm of the vandal latch and the driving shaft of the driving arm. In order to prevent unnecessary loads inside the lock box, the half moon clasp is also kept locked, which has the effect of double locking, which plays a role of correction, improving security and increasing convenience and versatility.
