DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an operation key having a function of displaying an applied / unlocked state of a cylinder lock.

[0002]

2. Description of the Related Art A plurality of drive magnets (permanent magnets)
Are arranged on the cylinder lock side, and the display magnet (permanent magnet), which rotates by its own attraction and repulsion with the drive magnet, is attached to the operation key side, and the cylinder key is locked by the operation key. The unlocked state is retained as the rotational directivity of the display magnet, and the locked state is maintained even after the operation key is removed from the cylinder lock by seeing the display magnet through a viewing window provided in the operation key. A magnetic force type unlocking / unlocking confirming device configured to be able to determine the unlocked state is already known in Japanese Patent Application Laid-Open Nos. 63-315779 and 4-38382.

[0003] When the operation key removed from the cylinder lock is carried or stored, the magnetic force of various permanent magnet-equipped articles corresponding to the drive magnet acts as an external force that hinders the holding state of the display magnet. To
In order to prevent the display magnet from inadvertently reversing and the display of the locked state and the unlocked state from being reversed, the first and second magnetic guide plates (7) and (8) are disclosed in JP-A-63-315779. ) Is attached, and the display magnet (5) is adsorbed and held on the display magnet.
Also, a magnet holding plate (4) is attached to the device, and the display magnet (8) is also attracted to the magnet holding plate (4).

[0004]

However, the former magnetic guide plates (7) and (8) and the latter magnet holding plate (4) are all in a fixed state in which the display magnets (5) and (8) are always attracted. Installed and its display magnet (5)
(8) and the drive magnets (13), (14), (8).

Therefore, no matter how strong the drive magnets (13), (14) and (8) on the cylinder lock side are, and how weak the display magnets (5) and (8) are, the magnetic force is set. Is inversely proportional to the square of the distance between the magnetic poles (Coulomb's law), so that the display magnets (5) and (8) are once attracted and held by the magnetic guide plates (7) and (8) and the magnet holding plate (4). Then, even if the display magnets (5) and (8) enter the reverse magnetic field of the drive magnets (13), (14) and (8), the display magnets (5) and (8) will continue to maintain the adsorption state.

That is, in the fixed arrangement of the magnetic guide plates (7) and (8) and the magnet holding plate (4), the display magnets (5) and (8) are to display the applied / unlocked state of the cylinder lock. Rotation operation itself is extremely difficult,
It cannot be provided as a product whose function and quality are stable regardless of use conditions.

In particular, since the former display magnet (5) is made of a flat permanent magnet, its assembly to the operation key (1) by the rotating shaft (6) is indispensable.
Since the magnetic guide plates (7) and (8) must also be formed as flat plates so as to correspond to the entire saw-tooth shape in positioning the display magnet (5), the processing and assembly are extremely complicated, and the mass production effect and light weight are achieved. There are also problems that cannot be achieved.

First, the entire trigger (T) is made of iron or the like.
Although it was explained that it was made from a magnetic material,
As far as possible, the trigger (T) should be
As a magnetic material, only the holding piece (18) which is a part thereof is used.
Even if it is magnetized by fixing and integrating a separate magnetic material,
Arguably good. Further, the display magnet (17) is not limited to the columnar type shown in the illustrated embodiment, but may be a spherical type or a spindle type.

FIGS. 15 to 18 show a second embodiment of the operation key (K) according to the present invention. In this embodiment, the display magnet (17) is moved forward from the holding piece (18) of the trigger (T). The fixed block (31) of (1) is integrally extended, and the hole (32) of the fixed block (31) is formed through the rear surface of the display magnet storage capsule (16).

The fixed block (31) of the trigger (T) which receives the back pressure of the coil spring (25) moves the display magnet (17) to the retractable hole (3) of the storage capsule (16).
Through 2), the display magnet (17) of the operation key (K) after being pulled out from the cylinder lock (L) can be fixedly held in a state in which it is not accidentally inverted by mechanically pressing directly from behind. -ing

In this case, the trigger (T) and its fixed block (31) can be made not only of a magnetic material but also of a non-magnetic material. This is because the display magnet (17) is fixedly held by the lid and the pressing mechanical force of the fixing block (31).

FIGS. 19 to 22 show operation keys (K).
According to the third embodiment, the display magnet (17)
A permanent magnet holding magnet (3
3) is fixedly integrated with the front surface of the holding piece (18) of the trigger (T) in a state of being enclosed in the storage capsule (34).

Then, the accidental reversal of the display magnet (17) after the operation key (K) is extracted is fixed and locked by the suction force of the holding magnet (33), while the operation key (K) is fixed to the cylinder lock ( When inserted into L), the holding magnet (33) is also retracted integrally with the trigger (T), and the holding magnet (33) is separated from the display magnet (17).

FIGS. 23 to 36 show fourth to sixth embodiments of the present invention corresponding to the first to third embodiments, respectively.
In the case of the third to third embodiments, when the trigger (T) is fitted into the knob (12) of the operation key (K) and installed, the trigger (T) is deviated leftward or rightward from the longitudinal center line of the key body (11). On the other hand, in all of the fourth to sixth embodiments, the trigger (T) is used.
Is extended on the longitudinal center line of the key body (11), and is fitted and installed in a knob (12) of the operation key (K). It is also evident from the illustrated embodiment that the hand of the key body (11) is in a so-called San-Germanic state due to its knob (12).

Since the other constructions and operations of the second to sixth embodiments of FIGS. 15 to 36 are substantially the same as those of the first embodiment, FIGS. Only a corresponding symbol is entered, and a detailed description thereof is omitted.

FIGS. 7 to 14 mentioned above illustrate 180-degree application / unlock type cylinder locks (L) which are often found in building doors, drawers of office equipment, and the like. More specifically, when the present invention is applied to such a model, a pair of upper and lower first and second drive magnets (29) and (30) are arranged and arranged on the vertical center line of the key hole (28). .

Then, it is now assumed that both magnetic poles of the first and second drive magnets (29) and (30) are in a phase change state as shown in FIGS. The display magnet (1) is located above the knob (12).
Assuming that 7) is fitted, when the operation key (K) is inserted into the key hole (28), FIG.
As will be apparent from the above, the display magnet (17) displays the unlocked state of the cylinder lock (L), for example, as a green color, by the suction action of the first drive magnet (29) facing the display magnet (17).

Then, from the unlocked state, the operation key (K)
When the cylinder lock (L) is locked by pivoting the cylinder lock (L) by 180 degrees of a constant rotation angle (θ), the display magnet (17) attached to the operation key (K) faces the second lock key (K). Due to the suction action with the drive magnet (30), it rotates by itself as shown in FIG.
The locked state of the cylinder lock (L) is displayed, and the operation key (K) is removed from the cylinder lock (L) at the locked position.

In the process of inserting the operation key (K), the trigger (T) for fixing and holding the display magnet (17), the fixing block (31), and the holding magnet (33) are used as described above. (17), and the magnetic or mechanical fixed holding force of the display magnet (17) is reduced by the first and second drive magnets (29) and (30). Since the magnetic attraction force is extremely weaker than the magnetic attraction force, the display magnet (17) can reliably and stably rotate in a state free from magnetic force.

Further, when the operation key (K) is removed from the cylinder lock (L), in either the locked state or the unlocked state, the display magnet (17) attached to the operation key (K) as described above. ) Is fixed and held irreversibly by the approach of the trigger (T), the fixed block (31), and the holding magnet (33), so that the first and second drive magnets (29) (30) )
However, there is no possibility that the display of the locked state or the unlocked state is reversed.

Next, FIG. 37 shows a 90-degree return type sinter lock (L) which is often found in the doors of automobiles and safes. In this case, the operation key (K) is turned by 90 degrees. After locking, it is possible to pull it out of the cylinder lock (L) by returning it by 90 degrees. However, when the present invention is applied to such a model, the key hole (28) is required. In other words, the left and right pairs of the first and second drive magnets (29) and (30) are arranged and arranged on the orthogonal horizontal center line.

FIGS. 38 and 39 show 90's of various bags.
The lock / unlock type cylinder lock (L) is illustrated as an example. In this case, the operation key (K) is turned by 90 degrees to lock, and then the operation key (K) can be removed at the locked position. However, when the present invention is applied to such a model, the first and second drive magnets (29) and (30) are placed on the vertical center line and the horizontal center line of the key hole (28).
Are arranged one by one.

Then, the operation key (K) of the present invention can be used for any of the models shown in FIGS.
It is possible to display the locked state and the unlocked state in the same manner as described above, and it is also possible to prevent the possibility of an erroneous display while the operation key (K) is being carried or stored.

In particular, depending on the type of bag, the 90-degree application / unlock type cylinder lock (L) may be installed in parallel as a symmetric pair as shown in FIGS. First and second cylinder lock (L1) (L2)
Must be set so that it can be locked and unlocked by one common operation key (K).

When the present invention is applied to such a model, as shown in the seventh embodiment in FIG. 42, the operation key (K) is symmetrically set with the longitudinal center line of the key body (11) as a boundary. A pair of upper and lower display magnets distributed (17a)
(17b) is also fitted and installed in the front end of the knob (12).

Then, the pair of display magnets (17)
a) (17b) is operated by one common trigger (T) so that it can be fixedly held similarly to the first embodiment. Then, in the process of inserting and rotating the operation key (K) into the first cylinder lock (L1) to perform the locking and unlocking, only one of the display magnets (17a) and (17b) is performed. By rotating, the locked state or the unlocked state is correctly displayed, and the remaining one is idle in terms of its function.

The operation key (K) is changed from the first cylinder lock (L1) to the second cylinder lock (L2), and when the second cylinder lock (L2) is locked and unlocked, Conversely, the display magnets (17a) (17
It can be said that only the other of b) rotates and functions to display the locked state or the unlocked state, and the other one is in the playing state.

However, in any case, the display magnets (17a) and (17b) of the operation keys (K) extracted from the cylinder locks (L1) and (L2) are the same as the trigger (T) as in the first embodiment. Thus, the display of the locked state and the unlocked state is not likely to be reversed later.

As shown in FIG. 42, the trigger (T) includes a pair of upper and lower holding pieces (18a) (18b) facing the display magnets (17a) (17b) from behind as shown in FIG. , Its holding piece (18a) (1
8b) and a pair of upper and lower slide guide pieces (20a) (20b) integrally extending rearward from one contact piece (1).
9), and the back pressure by one compression coil spring (25) acts on the pair of holding pieces (18a) (18b) equally.

At this time, instead of setting only the two holding pieces (18a) and (18b) hanging down on the entire trigger (T) or on the middle of the trigger (T) as the magnetic material, the above-described second and third embodiments are used. According to the configuration described above, separate upper and lower pairs of holding magnets (33a) (33b) may be installed in parallel immediately after the two display magnets (17a) (17b), or the two holding pieces (18a) (18b) ), The fixed blocks (31a) and (31b) can be integrally extended forward.

The trigger (T) itself and a coil spring (25) for applying a back pressure to the trigger (T) are separately and independently operated as a plurality corresponding to a pair of upper and lower display magnets (17a) (17b). Key (K) knob (1
