DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The disclosed technology belongs to the field of technology for the structure of a card lock that uses a card to unlock a fully locked lock attached to a door.

<Explanation of the gist> The invention of this application is a book that can be unlocked by moving a dead bolt forward and backward through a square core rod by rotating a thumb turn on the inside of the door or a cylinder lock on the outside of the door. The present invention relates to a card lock which is unlocked by inserting a card having a predetermined number of memory holes of a predetermined size into a predetermined position into a card lock of a case frame having a lock, and in particular, a card lock having a lock on the inside of the case frame. A cover is provided on the back side of the door, and a predetermined number of slideable control bars are set in the loose insertion holes provided in these, so that they are constantly pressed against the card by an elastic spring, and the memory hole of the card is A pair of narrow necks are formed at the bottom of the head of the control bar corresponding to the control bar, and a pair of narrow necks are mutually shifted in phase by 90 degrees in the rotation direction, and a key plate with a rectangular cross section is formed below the necks and is provided at the same level. The key plate is provided with a hole that can be loosely inserted into the neck, and a rotation hole for the connection is provided in the hole, and the key plate is provided with a hole that can be loosely inserted into the neck. The handle is engaged via a cam pin implanted in the boss of the handle provided on the outer surface of the case frame, and furthermore, the cylinder lock is linked to the handle via a gear mechanism. This invention relates to a card lock.

<Prior art> As is well known, various general locks have been developed for use on doors, etc., and most of them are cylinder locks that move the dead bolt forward and backward by inserting and removing a key and rotating it. using things.

However, in this type of cylinder lock type lock in which the dead bolt is moved forward and backward by key operation, unlocking and locking must be done by key operation.

Therefore, the lock only functions as a lock when the lock body and key, including the master key, are inseparably combined, and to that extent, there is a drawback that the lock function will be lost if the key is lost or damaged. According to statistics, there are many problems with locking due to forgetting to press the key, which is an inconvenience that is not desirable in terms of crime prevention.

<Problem to be solved by the invention> To address this problem, a so-called keyless type button lock, which is attached to the door surface and moves the dead bolt forward or backward according to the stored state by button operation, was recently invented by the applicant. It has been devised and put into practical use, and efforts have been made to improve the ease of use.

However, when it comes to permanent locks for rental rooms such as hotels, boarding houses, etc. that are rented for a temporary period, the troublesome point is that you are forced to change the predetermined memory number every time the rental is changed, and also for security reasons. It was hot.

Furthermore, when a contractor enters or leaves the common entrance of a hotel, etc. outside of curfew hours or late at night, employees and managers are forced to open and close the lock each time, creating problems in work management. In business hotels, etc., in particular, business hotels often have to impose strict curfews, etc., which impede the freedom of movement and freedom of work of contractors, and cause troubles from time to time. .

In recent years, with the development of computers, electronic locks and computer locks have been devised for hotels and other facilities that use magnetic cards or punch cards to operate locks by electrical operation. However, the problem was that attaching it to an existing door would be expensive and nearly impossible.

<Purpose of the Invention> The purpose of the invention of this application is to solve the technical problem of key operation and magnetic card operation of the main lock attached to the door based on the above-mentioned prior art, and to solve the problem of manufacturing and carrying of cards. It is easy to open and close not only by users but also by managers of hotels, boarding houses, etc., and it is also possible to open and close common entrances and doors, which will benefit the field of door technology application in the construction industry. Our goal is to provide an excellent card lock.

<Means/effects for solving the problem> In order to solve the above-mentioned problem, the structure of the invention of this application, which is based on the above-mentioned claims, is based on a case frame on the front side of the door and a button on the back side of the door. Remove the king plate from the door, remove the cover on the back of the case frame, reinstall the cover with only a predetermined number of control bars installed inside, and then install the full lock with the dead bolt that can move forward and backward. Rotate the control bar 90 degrees through the position display/conversion groove at the rear end, and use the elasticity of the key memory change plate slidably provided on the case frame to insert the key memory change plate into the corner of the control bar. The control bars are brought into contact with each other and biased to maintain their circumferential orientation, and by the above-described operation, two upper and lower nets set with 90° circumferential phase changes are attached to the upper part of the control bar, and each control bar's corresponding position is Position the mutual posture of the net to the set memorized posture, attach the case frame and bucking plate to the door via screws, and unlock the door from the state where the main lock of the door shows the closed state of the door. To open the door, insert a card with a memory hole corresponding to the orientation of the control bar into the insertion slit of the case frame and push it in. The card will slide along the case frame and the guide panel fixed inside. Then, the card slides, and the heads of the protruding control bars are pushed in one after another through the guide holes, and when the card is stopped inserted, the heads of the control bars corresponding to the set number of memory holes of the card are inserted. The chisel protrudes into contact with the memory hole, and then protrudes again into the memory hole by the elastic spring engaged with the control bar, so that the upper and lower two necks at the bottom of the head of each control bar are adjusted to the width of the key plate. All of the necks are aligned with the narrow notch and correspond to the passing posture, and when the handle attached to the outer surface of the case frame is rotated in the unlocking direction, the cam pin installed in the boss of the handle is rotated. comes into contact with the key plate and slides the key plate against the compression spring, so that the notch of the key plate passes beside the two upper and lower necks of the control bar, and the handle is fully locked. Rotate in the unlocking direction to unlock, while
If a card with a different control bar set position is inserted, the memory hole of that card does not correspond to the set control bar, so the setting control bar will not be inserted and protruded from the memory hole, and the handle cannot be opened. Even when turned in the lock direction, the upper neck of the control bar that does not protrude comes into contact with the shoulder of the notch of the key plate, and the key memory change plate is in surface contact with the corner of the control bar, resulting in The key plate becomes immovable and cannot be unlocked, and when no card is inserted, the lower neck of each protruding control bar engages with the shoulder of the key plate notch, resulting in the same result as described above. Basically, the key plate cannot be slid and cannot be unlocked, and furthermore, a cylinder lock is attached to the case frame so that the lock can be opened by operating the key of the cylinder lock. In this case, after closing the door, you can lock the main lock by turning the thumb on the back of the case frame, and after removing the card from the case frame, all the control bars will protrude and the lower part of the predetermined number of control bars will be locked. The lock becomes locked against the key plate, and by rotating the handle in the opposite direction, that is, in the locking direction, the cam pin rotates in the opposite direction without interfering with the key plate, and the square core rod is rotated in the opposite direction to fully tighten the lock. This is a technical measure that makes it possible to lock the

When the long groove 40 is in a position perpendicular to the long groove 40 by 90 degrees, it interferes with the shoulder 39 and restrains the sliding of the key plate 37, and as shown in FIG. 15, the long groove 40
If the posture is parallel to the shoulder part 39, it will not interfere with the shoulder part 39,
Therefore, the key plate 37 is allowed to slide.

Further, the head 50 of the control bar 43 is partially loosely inserted into the guide hole 42 of the guide panel 41 so that the card 18 can be freely inserted into the case frame 17.
When the control bar 43 is inserted into the slide groove 30 of the control bar 43, the control bar 43 is temporarily pulled inward (to the right side in the figure) as shown in FIG. When the memory hole 26 of the card 18 is in a corresponding attitude with respect to the head 50, the card 18 is plunged into engagement with the memory hole 26 and the card 18 stops sliding.

As shown in FIG. 9, a spring case 52 is provided at the inner end of the handle 22 and is fixed to the case frame 17. A return spring 53 is provided for returning from the dynamic position, and a boss 54 is provided at the tip (on the right side in the figure) of the return spring 53 so as to be rotatable relative to the case frame 17, and is integrated with the handle 22 via a square shaft 62. As shown in FIGS. 19 and 21, a pair of links 55, 55 are provided from the boss 54 in an approximately inverted V-shape upwardly in the drawing, and a left-handed cam pin and a right-handed cam pin are attached to the tips of the links 55, 55. 56 is provided by press-fitting so that the left and right sides can be exchanged freely, and the key plate 3
The cam pin 56 is pushed forward by the cam action against the 19th and 21st cam pins.
As shown in the figure, since the embodiment is right-handed, it is press-fitted into the link 55 on the right side when viewed from the back side.
When it comes into contact with the lower edge of the key plate 37 and rotates clockwise, that is, in the unlocking direction, the key plate 37 is raised against the elastic spring 34 in the drawing.

Therefore, when rotating in the opposite locking direction, that is, to the left, the cam pin 56 engages the key plate 3.
7, and because the cam pin 56 is not press-fitted into the other link 55, it does not interfere with the key plate 37, and there is no problem, and the key plate 37 is raised in the drawing by the elastic spring 34. , descend.

Further, as shown in FIG. 19, a gear 57 is provided at the tip of the boss 54, through which the square core rod 23 is inserted.

Therefore, the handle 22, the spring case 52,

5, 55, cam pin 56, and gear 57 form one block that rotates as the handle 22 rotates.

A cylinder cam 58 is integrally provided inside the cylinder lock 24 (on the right side in FIG. 9) provided under the handle 22 of the case frame 17, and a cylinder gear 59 is provided at the tip of the shaft.
is freely rotatable, and the cylinder gear 5
As shown in FIGS. 9 and 19, 9 forms a gear mechanism together with a gear 57 and is meshed with the same gear ratio.
0 and 60, as shown in FIG. 21, are fitted in a pair of fan-shaped adjustment grooves 61 and 61 bored in the cylinder cam 58 at the center angle of the rotation angle of the square core rod 23, and are arranged in the circumferential direction. It has a predetermined span of play.

As shown in FIGS. 9 and 21, there is a drum-shaped play notch 5 in the center of the boss 54 through which the core rod 23 is inserted.
5' is formed and a square core rod 23 is inserted,
When the handle 22 rotates and the boss 54 begins to rotate, the square core rod 23 rotates after the boss 54 begins to rotate at a certain angle in an idle state.

Therefore, the rotation of the handle 22 that causes the square core rod 23 to rotate does not immediately lead to the rotation of the cylinder lock 24, and the initial rotation of the pins 60, 60 is absorbed by the adjustment grooves 61, 61. Conversely, when a key (not shown) is inserted into the cylinder lock 2 to unlock it, the adjustment grooves 61, 61 have play relative to the pins 60, 60 so as not to interfere with the handle 22. Rotation is play notch 55'
After turning the set angle play through the square core rod 23 individually
It is designed to allow rotation of the

In the above configuration, a predetermined number of control bars 43, 43, . is attached to the door 1, and the control bar 43, 43, 4
3... is caused by the elastic springs 51, 51... to cause the tips 50, 50... to protrude from each guide hole 42 of the guide panel 41, that is, all the heads 5 are in the guide groove 30 in the case frame 17.
0, 50... are in the protruding state, the door 1 is in the released state, the cylinder lock 24 is in the released state, and the dead bolt 6 of the main lock 7 is retracted into the door 1. When closing the door and locking it, as mentioned above, open the handle 2 from the outside.
2 in the locking direction, or the thumb turn 13 from the inside in the locking direction, the cam pin 56
The link 55 on the side where is attached is separated from the key plate 37, and the other link 55 is attached to the cam pin 5.
6, the square core rod 23 rotates and the dead bolt 6 of the main lock 7 rotates upward without opening.
is projected and the main lock 7 is locked.

Of course, in this case, it is possible to insert a master key (not shown) into the cylinder lock 24 and lock it in the same manner as described above through the engagement of the cylinder cam 58 and the cylinder gears 59 and 57 via the pins 60, 60. .

Card 1 for door 1 locked in this way
It is impossible to open the door without using the key 8 or without using a master key (not shown).

That is, after the dead bolt 6 is locked as described above, each of the control bars 43 set in the case frame 17 has its upper end head 50 all protruding into the slide groove 30 by the elastic spring 51. , the lower net 48 of the group of control bars 43 shown in FIGS.
The lower nets 48 of the group of control bars 43 shown in FIGS. 13 and 14 are parallel to and aligned with the notches 40 of the key plate 37. Even if the handle 22 is rotated in the unlocking direction,
The cam pin 56 of the link 55 is connected to the key plate 3.
The notch 40 in FIGS. 15 and 16 allows the key plate 37 to slide against the net 48 on the lower side of the control bar 43. However, since the lower net 48 shown in FIGS. 13 and 14 is in a position perpendicular to the notch 40, it interferes with the shoulder portion 39 and prevents the key plate 37 from being pushed up as a result. Therefore, the handle 29 does not rotate, the square core rod 23 does not rotate, and as a result, the main lock 7 does not rotate, the dead bolt 6 cannot be pulled inward, and the lock cannot be unlocked. becomes.

On the other hand, the inner thumb turn 13 is connected to the square core rod 23, and the cylinder lock 24 is connected to the square core rod 23 via the cylinder cam 58 and cylinder gears 57, 59. When unlocking the cylinder lock 24 from outside using the key, the play notch 55' operates the square core rod 23 regardless of the rotation of the handle 22, so that the link 55 is not operated. Then, the main lock 7 is activated, the dead bolt 6 is retracted, and the door 1 can be released.

For unlocking with the card 18, the memory holes 26, 26...group of the card 18 are the 15th, 1st.
Since the holes are drilled only at positions corresponding to the posture of the control bar 43 shown in FIG.
Insert the card 18 into the 9th insertion slit 19 of 7.
As shown in the figure, when the control bars 43, 43, . ，
50... are pushed in one after another against the compression spring 51 from above.

The control bar 43 shown in FIGS. 15 and 16
Since the heads 50, 50, . . . of the group correspond to the memory holes 26, 26, .
The corresponding head 50 protrudes into the memory hole 26 due to the elastic force of 1, and therefore the 15th and 16th
As shown in the figure, the lower net 48 of the control bar 43
is in a state parallel to the notch 40 of the key plate 37, and is in a posture that allows the key plate 37 to slide.

On the other hand, the control bar 43 shown in FIG. 13 is pressed against the general surface outside the memory hole 26 of the card 18 and takes a pushed position against the elastic spring 51.
Accordingly, as shown, the upper net 49 is lowered into a position aligned with the notch 40 of the key plate 37, so that it is in a parallel relationship with the notch 40, which also allows the key plate 37 to slide. It will be set in a state where it can be done.

Therefore, when the handle 22 is turned in the unlocking direction, the cam pin 56 of one link 55 moves to the key plate 3.
7 and all control bars 4 as described above.
Since the upper and lower necks 48 and 49 of No. 3 are aligned at the same level with the notch 40 of the key plate 37 and are in a parallel posture, the key plate 37 is slid upward against the elastic spring 34,
The square core rod 23 begins to rotate, whereby the dead bolt 6 is retracted and unlocked, and the door 1 is opened.

While the card 18 is in its memory hole 26, 2
6... is inserted into another card lock 12 that does not have a control bar 43 corresponding to the group, the 15th,
The control bar 43 shown in Fig. 16 is pushed in by the general surface of the card 18, and the upper neck 49 is pushed down, so that it is perpendicular to the notch 40 of the key plate 37, and its shoulder 39 interferes. Then, the key plate 37 cannot be slid upward and the lock cannot be unlocked.

Further, the control bar 43 shown in FIGS. 13 and 14 protrudes across the key plate 37 and connects to the lower neck 4.
8 rises to be perpendicular to and at the same level as the notch 40 of the key plate 37, and at the same time its shoulder 39 interferes, making it impossible for the key plate 37 to slide.

Therefore, unless the corresponding control bar 43 and memory hole 26 match each other accurately, the key plate 37 will never be able to slide, and therefore the card 18 and the card It is ensured that the locks 12 are dedicated on a one-to-one basis only.

When the door 1 is opened, the card 18 is pulled out from the card lock 12 and the guide groove 3 is opened.
0 is released, the key plate 37 is returned to its original position by the elastic spring 34, the group of control bars 43 is elastically returned by the elastic spring 51,
The heads 50, 50, . . . project into the guide groove 30, and the handle 22 returns to its neutral position by its return spring 53.

Therefore, in the event of an unexpected accident or when it is desired to change the arrangement of the memory holes 26, 26, etc., the card 18 and the card lock 12 are dedicated on a one-to-one basis as described above. However, depending on the design of the card 18, changing the rows and columns of the memory holes 26, 26, etc. can be easily done without much difficulty.

On the other hand, to change the group of control bars 43 of the card lock 12, open the lid 15 of the bucking plate 11, and the group of control bars 43 protrudes rearward from the window 14 through the insertion holes 29, 29, . . . of the cover plate 28. Apply a screwdriver or the like to the minus groove of the display/conversion groove 45 at the rear end of each shank 44 of the row or column that needs to be changed, rotate it 90 degrees, and turn the screw 48.
Change the direction of 49 by 90 degrees.

By this operation, the control bar 43 group corresponding to the changed storage holes 26, 26... group of the card 18 is set to the upper and lower row nets 48, 49 as shown in FIGS. 15 and 16, and the key plate 3
For the control bar 43 group that does not correspond to
Change the posture of the nets 48 and 49 as shown in Figures 3 and 14 and set them.

In this case, the control bars 43, 43...
Due to the change in posture due to the 90° rotation, the corner portion 47 also changes.
Although the key memory changing plate 33 is rotated by 90 degrees, the linear contact surface 36 of the notch 35 provided on the key memory changing plate 33 comes into contact with the ridge portion of the corner portion 47, so that the key memory changing plate 33 is compressed by a kind of cam action. The control bar 43 slides back and forth by a set stroke against the spring 34, and the contact surface 36 directly presses against the corner surface 47 again, so that the always set attitude of the control bar 43 due to vibrations during handling, etc. Or,
It is maintained so that it does not change due to sliding movement due to insertion and removal of the card 18.

Alternatively, the back plate 27 and the cover 2
It is also possible to remove unnecessary numbers of control bars 43, 43, . . . or add them as shown in FIGS.

In the above-mentioned embodiment, it is not necessarily necessary to display the memory number in the form of characters at the position of each memory hole 26 for the card 18. In order to do this, as shown in FIG. 22, by utilizing the fact that the cover 28 is visible through the window 14 when the cover 15 of the bucking plate 11 is opened, the cover 28 is inserted directly below the position of each insertion hole 29, 29. It is possible to engrave each symbol or number on or display them as appropriate.

Further, in the invention of this application, various embodiments can be adopted, such as omitting the cylinder lock.

It is of course possible to change the design of the card by using a metal product instead of a resin product such as plastic.

<Effects of the Invention> As described above, according to the invention of this application, it is basically possible to use a lock for the door of a hotel, boarding house, etc. without informing the user of the number and allowing the user to enter and exit freely. , no management is required, and
Not only does it have the effect of making it easy to change the memory state, but it also has the excellent effect of allowing the user to easily carry the card in their pocket, commuter pass, etc. without taking up much space.

Further, since the card can be easily manufactured using resin or the like, it has the advantage of being easy to change and replace in terms of cost.

On the other hand, the lock itself can be easily rearranged in a wide variety of ways using a screwdriver, etc.
Another advantage is that there is no need to change the manufacturing of the lock itself.

In addition, there is no need for magnetic devices or wiring in magnetic card locks, electronic locks, etc., and the device can simply be attached to the door, which has the excellent effect of simplifying the overall system structure of the device.

Therefore, by providing a cover on the back and a stopper plate on the inside of the card lock,
An excellent effect is that the control bar attached thereto does not change due to the insertion and removal of the card.

In addition, by providing a head on the top of the control bar and forming two narrow necks below it with different phases of 90 degrees, the key plate can slide relative to the neck, and It is also possible to prevent the card from advancing or retracting due to interference with the shoulder part. Therefore, when the card is inserted into the insertion slit by the combination of these, if all the memory holes of the card are matched, As a result, the key plate can slide freely relative to the neck, and therefore, the card lock can be unlocked only in one-to-one use where the control bar and the memory hole of the card match.

Furthermore, since there are an almost infinite number of possible combinations of the row and column arrangement of the card's memory holes and the corresponding vertical arrangement of the control bar nets, a variety of one-to-one combinations can be made, making mass production possible. However, many card locks can be produced just by combining these, and therefore the same product can be applied to mammoth hotels etc., which has the excellent effect of reducing costs and making handling easier. There is also the effect of being easy.

Further, by providing a key memory changing plate under the key plate and providing a linear abutment surface for the corner portion of the control bar, there is an excellent effect that the set combination of the control bars is not easily disturbed.

In addition, by linking the cylinder lock under the handle via a gear mechanism, there is an excellent effect in that the master key can be used to deal with unexpected situations.
