 Conventionally, as a crescent locking method, a crescent with a key has been on the market, but the loss of the key makes it impossible to lock the lock and the trouble of key operation causes the theft accident due to the unlocking. For example, a house has many windows, each of which has a crescent, but in a crescent without a key, an intruder from the outside opens a part of the window glass, Open the window by opening and enter the house.

[0003] Therefore, a so-called keyed crescent, which has a key on the crescent for the purpose of preventing this, is widely used, but since there is a key on each of many windows, it is a heavy burden to open and close windows everyday. Moreover, if the keyholes are different, the number of keys will increase, and moreover, it is routine that the locked / unlocked window actually remains unlocked due to the loss of the key. Therefore, in order to improve this, a slide key was attached near the crescent and the crescent was locked and unlocked by operating the slide piece as a locking member, but this type of crescent has a key. Since the location is fixed and the outside intruder knows the location of the sliding key, the current situation is that an intrusion accident often occurs through a window.

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

In FIGS. 1 to 6, X is a crescent with a dial lock (hereinafter referred to as “crescent”). The Crescent X can be roughly divided into the main components, the case main body, the operation lever rotatably attached to the case main body, the dial member incorporated in the case main body, and the disengagement from the dial member. Further, it comprises a locking plate for locking or unlocking the operation lever. Therefore, the main parts of these constituent elements will be mainly described below.

First, 1 is a case body fixedly mounted on the side wall Y of the sash. The case body 1 is formed in a long box shape with one side opening. The form of the case main body 1 is not particularly limited, but it is formed at least at both ends or the peripheral end of the case main body 1 and has a mounting portion 2 for fixing the case main body 1 to the side wall Y of the window or sash. A mounting portion 3 for mounting an operation lever, which is formed at the central portion of the case body 1 or a portion from the central portion and which constitutes a part of the dial locking / unlocking mechanism, is required.

Thus, a through hole or a male screw hole 5 for the sash mounting screw 4 is formed at an appropriate portion of the mounting portion 2. Further, a relatively large diameter central hole 6 is formed in the mounting portion 3.

Although not necessarily required in this embodiment, for example, a lid mounting portion is formed to project at an appropriate location on the inner wall surface of the case body 1, and one side of the case body 1 is attached to the lid mounting portion. A lid that closes all or part of the opening 7 may be attached.

Reference numeral 12 is an operation lever that is rotatably fitted in the case body 1. The operation lever 12 is provided with an operation knob portion 13, a fitting projection shaft 14 that is connected to the tip portion of the operation knob portion 13 and is fitted into the center hole 6 of the case body 1, and the fitting projection shaft 14. 14, a semi-arcuate engagement piece 19 that engages with a hook-shaped crescent receiving metal fitting 15 that is connected to the upper side of 14 and that is attached to face the side wall Y of the window or sash.

Thus, the fitting projection shaft 14 is formed with a female screw hole 16 for a fixing tool, and an engaging plate 17 having an arc-shaped engaging cutout portion 17 a at a peripheral end is screwed into the female screw hole 16. It is fixed to the insertion end surface of the fitting projection shaft 14 via a male screw 18.

In this embodiment, the engagement plate 17 is fixed to the fitting projection shaft 14 by the fastener 18, but the fitting projection shaft 14 does not necessarily have the female screw hole 16 formed therein. It is also possible to further connect a small-diameter projection to the above and to fix the engaging plate 17 to the fitting projection shaft 14 by crimping the tip of the projection.

Next, 20 is rotatably attached to a shaft 21 projecting toward the one side opening 7 at a central portion or a portion from the central portion in the case main body through a central axial hole 22. It is a dial member. As shown in FIG. 1, the dial member 20 is provided inside the case body 1 separately from the operation lever 12.

In this embodiment, the dial member 20 has a dial operation portion 24 having dial indicators 23 such as “1” to “0” provided on the annular outer wall surface and one side surface of the dial operation portion 24.

And a recess 27 for releasing the locking plate in the shape of a semi-circle formed in the portion.

Reference numeral 28 denotes a washer, and the dial member 20 is pivotally supported on the case body 1 by using the washer 28 by crimping the tip end portion of the shaft 21, and a part of the peripheral body portion thereof is shown in FIG. It is exposed from the window portion or the cutout portion 8 of the case body 1.

Next, reference numeral 30 denotes a disk-shaped rotor that is axially supported by the shaft 21 of the case body 1 so as to face the engagement driving portion 25 of the dial member 20. The rotor 30 has a shaft hole 31 for the shaft 21 of the case body 1 at the center thereof, and one side surface 30a of the dial member 20 facing the engagement drive portion 25 is engaged with the drive claw 26 of the dial member. The driven claw 32 is formed to project. Further, on the peripheral side portion of the rotor 30, there is formed a locking plate relief recess 33 similar to the recess 27 formed in the dial member 20.

In this embodiment, the combination of the dial member 20 and the rotor 30 is illustrated. However, instead of the rotor 30, the rotor is provided with “1” to “0” on the annular outer wall surface. A second dial member having a dial mark 23 such as the above may be used, and a part of the peripheral body portion of the second dial member may be exposed from the window portion or the cutout portion 8 of the case body 1.

Next, 40 is pivotally supported in the case main body 1 so that the engaging head is located between the dial member 20 and the engaging plate 17 of the operating lever 12, and the engaging head is locked when it is locked.

Thus, the locking plate 40 has one end rotatably supported by the second shaft 41 provided at a portion from the side wall at the center of the case body 1, and the engaging head portion corresponding to the free end thereof. Reference numeral 42 denotes a jaw 42a that engages with the engaging cutout portion 17a of the engaging plate 17 when the dial locking / unlocking mechanism is locked, and is formed on the opposite side of the jaw 42a, and the dial locking / unlocking mechanism is used for unlocking. The dial member 20 and the rotor 30 sometimes have a head portion 42b that engages with the escape recesses 27 and 33, respectively.

Finally, 50 is a spring member that constantly urges the locking plate 40 in one direction so that the locking plate 40 can be fitted into the recesses 27 and 33 of the dial member and the rotor when unlocked. is there. The spring member 50 is wound around the second shaft 41, one end of which is in contact with the inner wall surface 1a of the side wall of the case body 1, while the other end is in contact with the peripheral side surface of the locking plate 40.

In the above structure, the crescent X is appropriately fixed to the side wall Y of the sash by the sash mounting screw 4 through the through hole or the male screw hole 5 of the case body 1.

When the operating lever 12 of the crescent X engages with the sash's crescent receiving metal fitting 15 and the dial locking / unlocking mechanism is locked, as shown in FIG. 4, the drive engaging portion of the dial member 20 is engaged. 25 and the respective peripheral side surfaces of the rotor 30. The head 42b of the head 42 is pressed against the peripheral side surfaces of the rotor 25 by the spring force of the spring member 50, and the jaw 42a of the head 42 is the operating lever. The twelve engaging plates 17 are engaged with each other so as to enter the engaging notches 17a. Therefore, the operating lever 12 cannot be rotated in the disengagement direction A 1.

Then, when the dial member 20 is rotated in one direction based on the personal identification mark (number, pattern, etc.), the driving claw 26 of the dial member 20 engages with the driven claw 32 of the rotor, and the rotor 30 is unlocked. Rotate to the sign position. On the other hand, when the dial member 20 is turned in the opposite direction and the unlocking mark is aligned with the position of the index (not shown), the head 42b of the engaging head 42 of the locking plate 40 is moved to the spring member 50 as shown in FIG. By the spring force of the dial member 20, the dial member 20 is fitted into the relief recess 27 and the recess 33 of the rotor 30 in such a manner as to straddle the jaws 42a of the engaging head 42 of the locking plate 40. The bar 12 is disengaged from the engagement notch 17a of the engagement plate 17. Therefore, the operation lever 12 can be rotated in the direction of the arrow A to release the engagement from the crescent receiving fitting 15.

In order to lock, the engagement piece 19 of the operation lever 12 is engaged with the crescent receiving fitting 15, and then the dial member 20 may be arbitrarily rotated.
