[Detailed description of the device]

[0001]

[Industrial application] The present invention is a window that can be opened and closed by rotating it.
The present invention relates to a lever type lock used for doors and the like.

[0002]

2. Description of the Related Art In some houses and offices, a simple lever lock is used to lock windows and doors. A conventional lever-type lock has a fixing portion that is fixed to a window that rotates and opens and closes, an operating lever portion, and an engaging portion that engages with a window frame or the like by rotating the operating lever portion. And a latch rotatably supported on the fixed portion.

[0003]

[Problems to be Solved by the Invention] In windows with glass, the lever lock can be easily unlocked by partially breaking the glass near the lever lock and rotating the operating lever of the latch. it can. For this reason, it was difficult to say that burglars could easily enter and that it had a sufficient effect on crime prevention.

An object of the present invention is to provide a lever type lock with high crime prevention.

[0005]

In order to achieve the above object, the structure of the present invention comprises a fixed portion fixed to a window which is rotated and opened and closed, and a latch which is rotatably supported by the fixed portion.
And a dial lock that locks the rotation of this latch.
For example, latch includes an engagement portion engaged with such window frame, the latch
A lever-type lock having a rotating operation lever portion , wherein the dial lock has a lock on the latch.
The axis of the ear is in the direction in which the operating lever extends.
Uni integrally provided, wherein the fixing unit may locking portion for locking the bolt member of the combination lock digits set.

[0006]

[Operation] With the unlocking member unlocked and with the locking member pulled, the window or the like is rotated and closed. And
The operating lever portion is rotated to engage the engaging portion of the latch with the window frame or the like. Therefore, the bolt member is turned toward the locking portion provided on the fixed portion, and the tip of the bolt member is inserted into the locking portion. Then, when the dial is properly turned, the bolt member is locked.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The lever type lock 10 has a fixed portion 11 and a latch 12 rotatably supported by the fixed portion 11, and the fixed portion 11 is fixed to a window 20 that is rotated and opened and closed by a screw. . The latch 12 includes an engaging portion 13 that engages with the window frame 21, and an operation lever portion 1 that rotates the latch 12.
4 and. The above is a well-known structure.

In this embodiment, a dial-type padlock 15 is integrally attached to the base of the operation lever portion 14,
The fixing portion 11 is provided with a locking portion 11a including a locking groove or hole into which the tip of the dial member 16 of the dial type padlock 15 is inserted. In addition, the bolt 16
In order to facilitate the operation of the bolt member 16, a knob portion 17 is attached. Here, the dial type padlock 15 includes a dial type padlock 15 in which
The thing which can lock the bolting member 16 in the state rotated by the arbitrary angle from the hole 15a side is used. In this embodiment, a dial 18 is used which can be locked by turning the dial 18 even in a state where the barbing member 16 is inserted in alignment with the locking portion 11a of the fixed portion 11. In addition,
In FIG. 2, reference numeral 22 indicates the inside and 23 indicates the outside.

Next, the operation will be described. FIG. 4 shows a window 20
With the knob 17 open, the tip of the bolt member 16 is pulled to the hole 15a of the dial padlock 15.
(See FIG. 2 and FIG. 3) FIG. When the window 20 is locked, the operation lever portion 14 is changed from the state shown in FIG.
Is rotated in the direction of arrow B to engage the engaging portion 13 with the window frame 21 as shown in FIGS. 1 and 2A. Therefore, as shown in FIGS. 2B and 3, the knob portion 17 is rotated so that the tip of the barbing member 16 corresponds to the locking portion 11a of the fixing portion 11, and then the tabbing portion 17 is pushed upward to move the barbing member 16. The tip of the is inserted into the locking portion 11a. Then, when the dial 18 is properly turned, the barbing member 16 is locked. When the window 20 is opened, if the dial 18 is set to a preset number, the lock of the bolt member 16 is released. Therefore, if the knob 17 is pulled downward to separate the tip of the barbing member 16 from the locking part 11a and the barbing member 16 is rotated in the direction of the dial padlock 15, the operation lever part 14 can be rotated.

Since the dial-type padlock 15 is incorporated in the lever-type lock 10 as described above, even if the glass near the lever-type lock 10 is partially broken, the preset dial number of the dial 18 must be known. For example, the operation lever portion 14 cannot be rotated, and the crime prevention performance is extremely high. In addition,
If, for example, a dial-type padlock 15 whose number can be changed freely is used, the number will not be forgotten by matching the numbers throughout the house. By the way, it is conceivable to attach an ordinary key to the crescent instead of the dial type padlock 15, but when the key is used, problems such as storage and loss of the key occur. In this respect, the dial-type padlock 15 does not cause such a problem.

[0011]

[Effects of the Invention] The lever-type lock according to the present invention has an extremely simple structure and a small number of parts, resulting in high cost.
Moreover , not only is the effect of high crime prevention obtained, but since a key is not required, there is no need to worry about storage or loss, and it is extremely easy to handle. Also, the dial lock is attached to the latch,
The axis of the dial of the dial lock extends the operation lever section.
Since it is installed integrally so that it is oriented in the
