Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lever-type lock used for windows, doors, etc. that can be rotated and opened and closed.

[0002]

[Prior art]

 Some houses and offices use simple lever-type locks to lock windows and doors. A conventional lever-type lock has a fixed portion that is fixed to a window that rotates and opens and closes, an operation lever portion, and an engagement portion that engages with a window frame by rotating the operation lever portion. And a latch that is rotatably supported by the fixed portion.

[0003]

[Problems to be solved by the device]

 For windows with glass, the lever lock can be easily unlocked by partially breaking the glass near the lever lock and rotating the latch operating lever. For this reason, it was difficult to say that burglars could easily enter the site and had sufficient effect in crime prevention.

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

[0005]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above-mentioned object is such that a fixed part for fixing to a window or the like which is rotated and opened and closed, an operation lever part and a window frame etc. are engaged by rotating the operation lever part. A lever-type lock having an engaging portion and a latch rotatably supported by the fixed portion, wherein a locking device is provided with a dial-type padlock, and the locking member locks the bolt-on member of the dial-type padlock. A part is provided on the fixed part.

[0006]

[Action]

 With the unlocking member unlocked and pulling out the locking member, rotate the window etc. to close it. Then, the operation lever portion is rotated to engage the latch engaging portion 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.

[0007]

【Example】

 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 which is rotated and opened and closed by a screw. . The latch 12 has an engaging portion 13 that engages with the window frame 21, and an operation lever portion 14 that rotates the latch 12. The above is a well-known structure.

In this embodiment, the dial padlock 15 is integrally attached to the base of the operation lever portion 14, and the fixed portion 11 is provided with the tip of the barbing member 16 of the dial padlock 15 for locking. A locking portion 11a including a groove or a hole is provided. A knob portion 17 is attached to the lid member 16 in order to facilitate the operation of the lid member 16. Here, the dial type padlock 15 is one that can lock the pinning member 16 in a state in which the pinning member 16 is rotated at an arbitrary angle from the hole 15a side of the dial type padlock 15. In this embodiment, a dial 18 is used which can be locked by turning the dial 18 even when the barbing member 16 is inserted in alignment with the locking portion 11a of the fixed portion 11. In addition, in FIG. 2, 22 indicates the inside and 23 indicates the outside.

Next, the operation will be described. FIG. 4 shows a state in which the window 20 can be opened and closed, and the squeezing knob portion 17 is pulled to separate the tip of the bolt member 16 from the hole 15a of the dial padlock 15 (see FIGS. 2 and 3). When the window 20 is locked, the operation lever portion 14 is turned in the direction of the arrow B from the state of FIG. 4, and the engaging portion 13 is engaged with the window frame 21 as shown in FIGS. 1 and 2 (a). Let Then, as shown in FIGS. 2 (b) and 3, the knob portion 17 is turned 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 push the barbing member 16. Insert the tip of the into the locking portion 11a. Then, when the dial 18 is properly turned, the bolt member 16 is locked. When opening the window 20, if the dial 18 is set to a preset number, the lock of the bolt member 16 is released. Therefore, the operating lever portion 14 can be rotated by pulling the knob portion 17 downward to separate the tip of the bolt member 16 from the locking portion 11a and turning the bolt member 16 toward the dial type padlock 15.

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 number of the preset dial 18 is known. If it is not, the operation lever portion 14 cannot be rotated, and the security performance is extremely high. If, for example, a dial padlock whose number can be changed freely is used, the number can be remembered 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 padlock 15, but using the key causes problems such as storage and loss of the key. In this respect, the dial-type padlock 15 does not cause such a problem.

[0011]

[Effect of device]

 The lever-type lock according to the present invention not only provides a very simple structure and high security effect, but also does not require a key, so there is no need to worry about storage or loss, and it is extremely easy to handle.
