[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. First, a lock having a deadbolt will be briefly described as a specific embodiment with reference to FIG.

A lock body 1 as an outer cylinder and a rotating body 2 as an inner cylinder are always inserted into the lock body 1 from the front. A boss is provided at the rear of the rotating body 2, and the boss is crushed and crimped with the washer and the dead bolt 3 interposed therebetween. In addition, as a means for preventing the rotating body 2 inserted into the lock body 1, a screw is provided at the rear of the rotating body 2 (not shown), and is fastened with a nut via a washer.

Alternatively, a groove is formed inside the lock body 1 at the rear, and a retaining ring is attached to the groove via a spring at the rear portion of the rotating body 2. Some of them jump out at the position (groove) and get caught in the groove.

A specific embodiment of the present invention will be described in detail with reference to FIGS. As can be understood from FIGS. 2 to 4, a cylindrical lock body 1 having lock fixing means as an outer cylinder.
A rotating body 2 having a keyhole 8 into which the key which is unlocked and rotated in the lock body 1 can be inserted when the concave and convex of the inserted key, which is the inner cylinder, and the locking means are aligned. In the existing lock, the rotary body 2 as the inner cylinder has a flange 4 formed on the front side where a key is inserted so as to engage with the spigot portion 7 of the lock body 1 as the outer cylinder. The display window 5 is formed by cutting out a part of the outer peripheral portion of the flange 4. An inner cylinder stopper 9 having an appropriate width for regulating rotation is formed at a diagonal portion of the display window 5.

The display window 5 may be covered with a transparent member that closes the display window. This transparent member can be more reliably visually recognized if it has the function of a convex lens.

A display member 6 'as a display section 6 is fixed to the lock body 1 as shown in FIGS. 4 and 6 so as to correspond to the display window 5 when the rotary body 2 is inserted. I have. In addition, the outer cylinder stopper 10 is formed integrally and substantially diagonally on the spigot-shaped step 7 of the lock body 1. The outer cylinder stopper 10 regulates the rotation of the rotator 2 with the inner cylinder stopper 9 formed on the rotator 2 and engaging with rotation. The display member 6 'has the same function and effect even when a color paint is directly applied to the lock main body 1 without being separately formed.

Further, as shown in FIG. 5, in the 90-degree rotary tablet, a key is inserted into the rotary body 2 and formed on the back side of a portion substantially opposed to the display window 5 of the rotary body 2 so that the key can be rotated 90 degrees. The rotation is restricted by an inner cylinder stopper 9 for restricting rotation and an outer cylinder stopper 10 formed substantially at the center of the lock body 1 so as to face each other. Then, when the key is inserted into the rotating body 2, if the position is the locked state (a), then 90
The rotating body 2 is rotated by the degree key to bring it into the unlocked state (b). As the rotating body 2 rotates, the position of the display portion of the display window 5 formed integrally with the rotating body 2 moves, and the display position changes at the same time as visual confirmation by color, so that the open / closed state can be extremely reliably established. It can be determined.

Next, a 180-degree rotary tablet will be described with reference to FIGS. The 180-degree rotary lock inserts the key into the rotary body 2 and rotates the rotary body 2 from the locked state (a) to the unlocked state (b). As the rotating body 2 rotates, the position of the display portion of the display window 5 formed integrally with the rotating body 2 moves, and the visual confirmation by color is performed in the same manner as the 90-degree rotary lock described with reference to FIG. At the same time, the display position (up and down in this embodiment) changes, so that the open / closed state can be determined very simply and reliably.

Although the specific embodiment has been described above, the rotating body 2 is provided with a rotating body 2 such that the rotating body 2 is stopped when rotated 90 degrees or 180 degrees to the left and right, respectively. The inner cylinder stopper 9 is provided with an outer cylinder stopper 10 on the lock body 1, and in particular, a 180-degree rotary lock is provided on the lock body 7 of the lock body 1 as shown in FIGS. 8 and 9.
The display member 6 ′ which is engaged with the lock member 1 has a semicircular shape of approximately 180 degrees, and halves thereof are, for example, an open blue portion and a closed red portion. The inner cylinder stopper 9 formed on the rotating body 2 has a height that slides on the outer cylinder stopper 10 so that it can rotate about 270 degrees between both ends of the cylinder stopper 10. 1 between the approximately 90 degrees of the play portion 11 and the approximately 90 degrees of the play portion 11
It can rotate by 80 degrees. Therefore, as shown in FIG. 8, it is needless to say that the outer cylinder stopper 10 is formed by providing a cutout portion of approximately 270 degrees including the play portion 11 of about 1/4 circle.

Next, because of the above-described configuration,
A display unit is provided on a lock body 1 of an existing cylinder lock, a rotating body 2 to be inserted into the lock body 1 is provided, and a display window 5 is formed on the rotating body 2 corresponding to the display unit of the lock body 1. So
By inserting the key into the keyhole of the rotating body 2 and rotating it,
When the rotator 2 is rotated, the display window 5 of the rotator 2 is also rotated at the same time, and the visible portion of the display unit of the lock body 1 changes. For example, when the displayed portion is closed, it is red, and when it is open, it is open. It is provided so that a blue display portion appears.

Next, in order to display the display portion 6 as close as possible to the front side by directly displaying the color on the lock body 1, a rotary stopper is formed at the rear portion as shown in FIGS. This can be solved with a 90-degree rotary tablet.
The 80-degree rotary tablet is also realized by the same technical idea. In the case where the display unit 6 for directly displaying a color is a 90-degree rotary tablet, FIGS.
In the case of a 0-degree rotary tablet, it is displayed as shown in FIG.

Also, the display member 6 'shown in FIGS. 8 and 9 is replaced with a display member 6' having a semicircle of approximately 180 degrees which is rotatably provided, as shown in FIGS. In the case where the display unit 6 is opposed to the display unit 6 for approximately 90 degrees, a separate display member 6 ′ is fixed in the arrangement shown in the drawing or directly by color display. An inner cylinder stopper 9 of about 1/4 yen is formed so as to face the outer cylinder stopper, and an outer cylinder stopper 10 of approximately 90 degrees is formed in a portion of the lock body 1 where the display part 6 is removed from the spigot part 7. is there.

In this case, it is impossible to provide the display member 6 'separately and bring the display member 6' closer to the surface than the outer cylinder stopper 10. However, as shown in FIGS. The position (deeper than the outer cylinder stopper), but if this is permissible, it is also possible to adopt the configuration as in this embodiment.

[0024]

According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) The trouble of linking the key and the display mechanism as in the related art can be eliminated, and no space is required.

(2) Since it becomes possible by slightly processing an existing lock, the cost can be reduced.

(3) Since the display position of open / close changes, even if it is impossible to recognize by color even from a distant place, it can be recognized at the position.

(4) In a shared furniture, it is convenient because the open / closed state of the key can be visually recognized when used.

(5) As the management of documents in a company, the open / closed state of the key can be visually confirmed.
