Description

Description: TECHNICAL FIELD The present invention relates to a magnetic card type switch which can be turned on by a magnetic card, or the switch can be kept on and off, and the switch casing can be opened.

BACKGROUND ART Conventionally, a device for locking or unlocking a lock using a magnetic card, for example, is known.
This is disclosed as a "lock structure" in JP-A-41391. The configuration includes a slider movable from a locked position to an unlocked position by inserting a magnetically encoded magnetic card, and a slider slidable in a direction perpendicular to the sliding direction of the slider within the slider. A lock plate is provided for locking the slider having a magnet lock pin and a hole provided along the slider, the lock having a hole that protrudes from the slider and is received when the slider is in the locked position.

However, according to the above-mentioned conventional example, when a mechanism in the lock casing (in this case, the knob of the door) is broken and the inside needs to be inspected, or when it is desired to change the magnetic code of the magnet lock pin. However, there is a disadvantage that it is difficult to open the casing, that is, to disassemble the casing, and it is very troublesome to perform such operations.

As another conventional example, there is a "casing for a card lock" disclosed in Japanese Patent Application Laid-Open No. 2-28658 to solve the above-mentioned disadvantages of the conventional example. According to this, a lower casing attached to a wall or the like of a building, an upper casing detachably attached to the lower casing, and a coupling engagement means for coupling and coupling the upper casing to the lower casing are included. The slider accommodated in the space limited to the above is slid by inserting a regular magnetic card coded magnetically into the casing to turn on a switch for locking and unlocking the lock. In some cases, at the same time, the casing is easily disassembled by releasing the engagement by the connecting engagement means in conjunction with the movement of the slider.

However, according to this conventional example, in order to maintain the ON state of the switch, the state in which the magnetic card is inserted must be maintained. That is, when the card is removed, the switch is automatically turned off. Therefore,
When this switch device is applied to, for example, the on / off operation of a certificate, instead of the on / off operation of a lock, it is troublesome to hold the on state of the certificate, and it is not practically applicable. There was a disadvantage. Also, disassembling the casing involves an extra operation that the switch must be turned on at the same time, so even if you lend a magnetic card to a third party to turn on the switch, for example, In addition, there is a disadvantage that the casing may be disassembled, the internal mechanism may be tampered with, or the magnetic code may be changed.

15 to 19 show various magnetic cards used by being inserted into the switch assembly. FIG. 15 shows an on-key card 31, FIG. 16 shows an off-key card 32, and FIG. 17 shows a momentary key card 33. FIG. 18 shows an open key card. Each card has a bend cutting line 6 in FIG.
-6 along the (same as section line 5b-5b of the lock plate 7 of FIG. 2), i.e. in positions corresponding to the positions of the lock plate 7 _{'a 1, c 2, a 2} , a 3 ' An S-pole magnet indicated by a “plain pattern” or an N-pole magnet indicated by a “black-painted pattern” is embedded as needed (the polarity is indicated by the side of the magnet embedded in each card near the magnet lock pin 21 when the card is inserted). FIG. 19 shows an on / off dual-purpose key card 35 in which an on-key card 31 and an off-key card 32 are combined.

Next, the operation of the magnetic card type switch will be described.

First, the on-key card 31 shown in FIG. 15 (buried magnets of N, S, N, and N poles are arranged at each of the positions “a ₁ , c ₂ , a ₂ , a ₃ ”) to turn the switch 24 on. 6) is inserted into the inside of the assembly through the card insertion hole 1a on the left side in FIG. 6 until it comes into contact with the contact portion 9f of the second slider 9-2. At this time,
The cross section of the card in FIG. 6 is along the cutting line 6-6 in FIG. 15, and the same applies to the following drawings.

Then, as shown in FIG. 6, both sliders 9-1 and 9-
2, the magnet lock pins 21a ₁ , 21c ₂ ,
21a ₂ and 21a ₃ respectively correspond to the respective embedded magnets at the corresponding positions of the on-key card 31. Therefore, the lock pins 21a ₁ , 21c ₂ , 21a ₃
6 correspond to the buried magnets having different polarities, respectively, and are further pulled downward in FIG. 6 to maintain the same position as in FIG. 5, but only the lock pin 21a ₂ corresponds to the buried magnet having the same polarity and is repelled. As a result, the second slider 9-2 is unlocked by the lock plate 7, that is, is in a slidable state.

Accordingly, when the on-key card 31 is further pushed in against the coil spring 13, the second slider 9-2 slides backward together with the on-key card 31 to reach the position shown in FIGS. 7 and 8. Accordingly, the lock pins 21c ₂ , 21a ₂ , and 21a ₃ respectively correspond to the respective positions “c ₂ ,
a ₂ , a ₃ ”to each position“ c ₃ , a ₃ , a ₄ ”. However, since the through holes are not provided at the positions “c ₃ , a ₃ ” of the lock plate 7, the lock pins 21 c ₂ , 21 a ₂ cannot move down. However, the corresponding position of the lock pin 21a ₃ of the rightmost "a _4" since the through-holes 8a ₄ is provided, the lock pin 21a ₃ is attracted to the buried magnet different polarities of the card 31 pores Go falls into 8a _4, second slider 9-2 by the which is locked (held) in the backward slide position via the lock pin 21a _3.

At this time, as shown in FIGS. 7 and 8, the switch switching section 12a presses the switch 24 to switch to the switch-on state. At the same time, from the window 1g, the green part 12 of the plate 12
c is switched and the switch-on state is displayed.

Next, even if you remove the card 31, all lock pins
21a ₁ , 21c ₂ , 21a ₂ , and 21a ₃ are subsequently attracted to the magnetic plate 5, and the state similar to that of FIG. 8 is maintained. Therefore, the switch-on state is maintained.

Next, the switch-on holding state shown in FIG. 8 is released to make the switch-off state. First, an off-key card 32 shown in FIG. 16 (N at each position “a ₁ , c ₂ , a ₂ , a ₃ ”)
Buried magnets of S, S, and S poles) are inserted until they come into contact with the contact portion 9f at the backward sliding position as shown in FIG. Then, only the rightmost lock pin 21a ₃ is the card
32 because it corresponds with embedded magnets of the same polarity exit the hole 8a ₄ of the lock plate 7 to rebound, whereby the second slider 9-2 is slidable state is unlocked condition.

Therefore, when the card 32 is removed from the state shown in FIG. 9, the second slider 9-2 also returns to the state shown in FIG. 5 by sliding back to the left by the spring force of the coil spring 13. At this time, as shown in FIG. 5, the locking pin 21a ₂ plunged second slider 9-2 through hole 8a ₂ again is locked again in the initial position. Therefore, the switch 24 is turned off, and the red portion 12b indicating the switch-off state is displayed again on the window 1g.

Next, the switch 24 is turned on (that is, not kept on) only when the card is inserted. This includes the momentary key card 33 shown in FIG. 17 (positions “a ₁ , c ₂ ,
a ₂ , a ₃ ”, respectively, buried magnets of N, S, S, and S poles) are inserted until they come into contact with the contact portion 9f as shown in FIG. Then, the two right lock pins 21a ₂ and 21a ₃ repel and move upward in correspondence with the embedded magnets of the same polarity of the card 33.
Accordingly, the lock pin 21a ₂ is brought out of the hole 8a ₂ of the lock plate 7, whereby the second slider 9-2 is slidable state is unlocked condition.

Therefore, when the momentary key card 33 is further pushed in and slid backwards together with the second slider 9-2, the moment reaches the position shown in FIG. 11, which is almost the same as the case of FIG.
Accordingly, the switch 24 is turned on as in the case of FIG. 8, and the green portion 12c is displayed in the window 1g.

However, in the case of FIG. 11, the rightmost lock pin
21a ₃ when moved position from the "a _3" to "a _4", it does not move fall into the hole 8a ₄ while being repelled by the same polarity of the buried magnet above as card 33. Accordingly, when the card 33 is removed from the state shown in FIG. 11, the second slider 9-2 is not held at the ON position, but is slid to the left integrally with the removal movement of the card 33 by the spring force of the coil spring 13. Then, it returns to the state of FIG. When the card 33 is completely removed, the lock pin 21a ₂ is again put on the lock plate 7.
Lock the second slider 9-2 moves falls into the hole 8a _2. At the same time, of course, the switch 24 is turned off and the red portion 12b is displayed on the window 1g.

That is, according to the momentary key card 33, the switch 24 can be turned on only while the card is being inserted.

Next, when the inside of the built-in body breaks down or the combination of the lock pins (that is, the magnetic code) is changed,
The operation of removing only the cover casing 1 while leaving the mounting casing 22 as it is will be described. To do this, first, after removing the pair of screws 23 in FIG. ₁ , the open key card 34 shown in FIG. 18 (in each position “a ₁ , c ₂ , a ₂ , a ₃ ”, S,
Buried magnets of N, N and S poles) are inserted until they come into contact with the contact portion 9f as shown in FIG. Then, all the lock pins repel and move upward in correspondence with the embedded magnets of the same polarity of the card 34. Therefore, in particular, the lock pins 21a ₁ and 21a _{2 respectively} come out of the holes 8a ₁ and 8a ₂ of the lock plate 7, whereby the first and second sliders 9-1 and 9-2 are unlocked and slid, respectively. State. at the same time,
The lock pin 21c ₂ moves upward and the upper end thereof is moved to the first slider 9
Since engages the guide hole 9c ₂ -1 guide portion 9a, both 2
The slider 9-1 and 9-2 will be integrally slidable state via the lock pin 21c _2.

Therefore, when the open key card 34 is further pushed in and slid backward together with the sliders 9-1 and 9-2, the position shown in FIGS. 13 and 14 is reached. This allows
The engagement pin 11 of the first slider 9-1 comes out of the engagement hole 22a. Therefore, the cover casing 1 is gripped and
1h, the cover casing 1 can be easily removed by rotating the engagement recess 22d around the engagement portion, and repair of the failure or change of the magnetic cord can be performed.

In FIG. 14, since all the lock pins remain repelled upward, they do not fall into the through holes of the lock plate 7. Therefore, since the state shown in FIG. 14 cannot be maintained, the cover casing
It is necessary to remove and reattach. .

When the cover casing 1 is attached and returned, the open key card 34 is removed. Then, both sliders 9-
The slide pins 1 and 9-2 also return together with the card 34, the engagement pins 11 return to the engagement holes 22a, and all the lock pins 21 return to the state shown in FIG. After that, the screw 23 is mounted again.

When the on / off combined key card 35 of FIG. 19 is inserted into the assembly in the direction of the arrow `` ON '' in FIG. 19, the switch-on holding state can appear similarly to the above-mentioned on-key card 31, and vice versa. When inserted into the assembly in the direction of the arrow “OFF”, the holding state of the switch-off state can appear as in the case of the off-key card 32. In other words, there is an advantage that one card can perform both on and off functions.

2, the position of the through hole 8 of the lock plate 7,
It is clear that the number of lock pins 21 and the insertion position thereof can be changed as appropriate. For example, when the lock plate 7 is used without changing the position of the through hole 8 in the lock plate 7 in FIG. 2, the polarity of the lock pin 21 and the magnetic cards 31 to 35 are all reversed from those in the above embodiment. Is also good.

As still another example, each lock pin 21 at the position “c ₂ , a ₂ , a ₃ ” cannot change its position, but the lock pin 21 at the position “a ₁ ” for locking the first slider 9-1. the lock pin 21 may be arranged in more than two locations is good or position changed to any position "b ₁ to e _1" instead of the position "a _1", "a ₁ to e _1".

Further, of all the positions corresponding to the second slider 9-2, the position “c ₂ , where the lock pin 21 is already disposed,
a _2, a ₃ 'position with a through-hole 8 other than _{"b 2, b 3, d 2} , d 3,
e _2, e ₃ "in may be arranged additional locking pin.

Therefore, even if the lock plate 7 is assumed to be of one type, an enormous number of magnetic codes can be set, and by simply changing the number, arrangement, and magnet polarity of the lock pins with the same device, It is possible to sell magnetic card switches with different magnetic codes to a number of different customers. If the position of the through hole 8 of the lock plate 7 is changed, it can be applied to a larger number of customers.

Further, in the above embodiment, the switch 24 was kept off before the magnetic card was inserted for the first time. However, the present invention is not limited to this, and depending on the application, the switch 24 may be turned on first before the card is inserted. Of course, it may be in the holding state. In this case, by inserting the magnetic card first, the switch can be switched to OFF or OFF without holding.
