The present invention mainly relates to a card key device used for attaching to a door of a hotel room or officetel or apartment entrance. In the door lock system, which is generally used, an open door is automatically closed and automatically locked. When opening it again, only the handle of the locking device should be rotated inside, but from the outside, the key must be used unless it is opened from the inside. If there is an auxiliary key device, there must be a separate external key to operate it only. Is the same if the key is a general mechanical or card key.

In particular, in the case of a card key, the internal structure is complicated, and a lot of force is applied to the card, thereby shortening the use sleep.

However, the present invention allows the auxiliary key device to be opened and closed at the same time as a single card key and at the same time, even when the door is opened automatically, the automatic locking operation is stopped and the door can be freely opened without a key from the outside. In order to open and close and at the same time to operate the locking device as a card key to prevent excessive force is applied to the key of the card to prevent damage of the card key as in the prior art and thus to diversify the function of the card key device. At the same time, in order to achieve the purpose of reducing the force applied to the key on the card, the auxiliary locking device and the main locking device are interlocked. Innovative improvement and reversal of pores in magnet housing and magnetic plate If the above-described according to the accompanying drawings, the configuration and operational effect as that follows.

Inner and outer handles (1) (2) and cover plates (3) (4) and clasps (5) and low barrels (6). In the known card key device, which interlocks with the interlocking portion (5) and connects another quadrangular bar (9) to the subsidiary chain lock operation lever (8) to operate the sublocking device (10). (4) cut the hexadecimal rod (7) connected to the two-handed grip (1) (2) through the hexahedral hole (11) from the outer side of the clasp part (5) to form the inner quadrilateral rod (7 ') and the outer quadrilateral rod ( 7 ") and then form the female threaded portion 12 and the male threaded portion 13 on each cut portion of both quadrangular rods 7 ' and 7 " The outer quadrangular rod 7 "which is retained by the outer handle 2 of the outer cover plate 4 without the rotational force of one quadrangular rod 7 'or 7" being transmitted to the other quadrangular rod 7' or 7 ". ) Is inserted into the square hole 18 of the rotating disc 17 having the locking jaw 15 and the locking projection piece 16. Fill the fixing pin 19 with the hexagonal rod 7 "so that the rotating disc 17 is not separated from the hexagonal rod 7", and then the torsion spring 20 having the extension part 20 'on both sides is outside. The locking projections 16 and the outer cover plate 4 of the rotating disc 17 are inserted into the projection 21 formed in the cover plate 4 so that both extending portions 20 'pass through one side of the cover plate inner projection 21. ) To the inner wall.

A recessed groove 24 is formed in the outer circumferential surface, and a quadrangular rod 7 "is formed in the square hole 28 drilled in the center of the sliding disk 27 having a horn 25 on both sides and a predetermined thickness 26. After passing through, the inner circumferential surface 30 of the insertion groove of the magnet barrel 6 operating piece 29 is configured to be inserted into the recess groove 24.

And the bending end portion 31 is formed in the middle, and one side has an elliptical hole 32 and a lateral elliptical hole 33, the other side has a circular hole 34 in the middle and a long hole 35 on both sides The plate 36 is formed to penetrate the hexahedral rod 7 'through the circular hole 34, the octagonal hole 32 penetrates the octagonal rod 9 of the auxiliary clamping device, and A sliding disc 27 in which a quadrangular bar 7 "penetrates the quadrangular hole 18 so that the tip projection 39 of the connector 38 through which the quadrangular bar 9 penetrates into the square hole 37 is inserted. While forming a certain space 40 between one side and the other side of the operating plate 17, the junction portion 14 of the quadrangular rod 7 must be located in the space 40 and the sliding disk 27 is When sliding, the horn 25 is configured to be inserted into the long hole (35).

Since the internal structure of the magnet barrel 6 is general, a description of the specific configuration is omitted here, but it has a plurality of magnet barrels and balls 42 ', and the two bending connecting rods 60 are formed of the magnet housing body 44. When the tip of the card key 41 pushes the projection 43 of the thin magnetic plate 42 which performs a simple reciprocating motion on both side recesses 61, the connecting shaft 62 is connected to the tip of the connecting rod 60 of the magnetic plate. The working piece 29 of the working piece 29 'which is arranged to be configured to linearly move in the longitudinal direction of the quadrangular bar 7.

In addition, when one or more reverse holes 45, that is, the plurality of magnet through holes 42 'are opened in the magnet housing body 44 having the magnet plate 42 or the magnet holder holes 44', The ball 45 is closed and the former is formed by forming the reverse opening 45 when the former is closed. Reference numeral 50 denotes a key insertion hole, 51 a display plate, 52 a see-through hole, and 53 a spring.

The present invention configured as described above can use two types of keys, one for general use and one for special use.

At this time, when the card key 41 is inserted into the key insertion hole 50, the door is opened and the key 41 is removed. The method of use is the same as in the conventional case, but the inner working is remarkably different from the conventional case. It is different.

That is, when the card key 41 is inserted into the key hole 50, the locking device is released by the arrangement of the internal magnets 46 as in the prior art, but the tip of the card key 41 pushes the protrusion 43 of the magnetic plate 42. When the magnetic plate 42 itself slides lightly on the upper surface of the magnetic enclosing body 44, the working piece 29 connected to the bending section 60 of the magnetic plate 42 also operates. In this case, the sliding disk 27 moves in the longitudinal direction of the quadrangular rod 7 because the operating piece 29 is inserted into the recessed groove 24 in the space 40. In accordance with this, the horns 25 of the humidity disk 27 are caused to be inserted into the holes 35 of the operating plate 36, respectively, but the rotation disk 17 is fixed by the pin 19 4 There is no longitudinal movement of each bar (7).

At this time, it is important that the junction 14 of the quadrangular rod 7 enters the thickness 26 of the sliding disc 27 in accordance with the change of the position of the sliding disc 27 so that the outer quadrangular rod 7 "and the inner side are moved. When the four-sided rod 7 'is interlocked, that is, when one side of the four-sided rod 7' or 7 "rotates, the other side of the four-sided rod 7 'or 7" is also placed in a rotatable state.

At this time, when grasping and turning the outer handle 2, the rotating disc 17 is rotated according to the hexagonal rod 7 is inserted into the octagonal hole 18, but the limit is that the locking jaw 15 is outside It rotates only until it catches the protrusion 23 inside the cover plate, and as described above, the junction portion 14 of the outer quadrangular rod 7 "and the inner quadrangular rod 7 'has the thickness 26 of the sliding disc 27. ), The rotational force of the outer quadrangular rod (7 ") is transmitted to the inner quadrangular rod (7 ') through the four processing 28 of the sliding disk (27).

In this case, the inner quadrangular rod 7 ′ penetrates the octagonal hole 11 of the clasp 5, whereby the clasp 5 is operated and the inner handle 1 is also operated together. The internal operation of the government 5 is well known and its description is omitted here.

Meanwhile, the horns 25 of the sliding disk 27 are inserted into the long holes 35 of the operating plate 36, so that the rotational force of the quadrilateral rod 7 by the operation of the outer handle 2 is obtained through the operating plate 36. The rotating plate 36 is rotated, and the operating plate 36 which rotates around the circular hole 34 is connected to the connector through the tip projection 39 of the connector 38 inserted into the lateral elliptical hole 33. 38) rotates around the quadrilateral hole 37. Therefore, the rotational force of the four-rods 7 causes the rotation of the four-rods 9, and the four-rods 9 are four-holes 10 '. By operating the auxiliary determination device 10 through, after all, it is possible to operate the main determination device 5 and the auxiliary determination device 10 at the same time as one card key.

At this time, the quadrangular bar 9 is penetrated in the longitudinal elliptical hole 32 of the operating plate 36, but the elliptical hole 32 is largely formed in the longitudinal direction. It does not interfere with the rotational movement of 36).

In addition, the display panel 51 attached to the outer end thereof according to the rotation of the quadrangular rod 9 also rotates along the two constructions 52 so that it can be checked from the outside.

Open the door by turning the outer handle (2) as described above, remove the card key 41 from the insertion hole 50, the magnetic plate 42 is restored to the original position by the elastic force of the spring 53 and at the same time Rotation of the rotary disk 17 by the extension 20 'of the torsion spring 20, which is locked by the magnets and pushes the locking projection 16 of the rotary disk 17 As a result, the rotational force restores the outer handle 2 to its original position through the quadrangular rod 7.

Next, the operation in the case of using a special card key will be described.

In the present application, as described above, one or more reverse-order holes 45 are formed in the magnet housing 44 having the magnet plate 42 or the plurality of magnet receiving holes 44 'to form the plurality of magnets 46. When the reverse hole (45) is closed when the opening is closed, the latter is open when the former is closed. If the magnetic design is used to operate only the special card, the magnetic plate (42) is pushed when the special key is inserted into the key hole (50). When the card key device is released, the reverse hole 45 of the magnetic flux plate and the reverse hole 45 of the magnet housing 44 coincide with each other so that the magnet 46 inside thereof hangs the magnetic plate 42. Even if the special card key is removed, the magnetic plate 42 cannot be returned to its original position. Therefore, the card key device always remains unlocked. When this happens, the door can be freely opened without the card key. When the special card key is inserted upside down, the magnet in the card key acting on the magnet 46 in the reverse hole 45 is reversed and the magnet plate 42 is pushed out by pushing the magnet 46 in the reverse hole 45. If the card key is removed, it returns to its original position and is corrected again. If the card key 41 is not present, the door cannot be opened thereafter.

The other actions when using this special card key are the same as when using a general card key. Therefore, the explanation is omitted here. This special card key can be opened and closed from the outside freely without a card key. For example, when you clean a hotel room or use the officetel as an office during the day, you can use it conveniently.

As can be seen from the above, the design of the thin magnetic plate 42 itself slides lightly on the upper surface of the magnetic enclosing body 44, and the quadrangular rod (7 ') (7 ") detachment structure is very simple. As there is no heavy force applied to the key as in the prior art, there is no hand of the card key, and the auxiliary locking device can be opened and closed together as a single card key without a separate auxiliary key. It is a useful design that allows the door to be opened freely without a key.

Of course, as another embodiment of the present invention, the operation plate 36 and the connector 38 and the horn 25 of the sliding plate 27, which are interlocking means of the hexagonal rod 7 and the octagonal rod 9, do not install the auxiliary lock. The device 10 may use a separate mechanical key as in the prior art, and in another embodiment, by omitting the formation of the reverse hole 45 in the magnet barrel 6, and using only one card key of the botto, You can use the card key every time you open the door.
