[Industrial applications]

 The present invention is a sliding sash window or door (hereinafter simply referred to as a window) as a ventilation lock for locking a slightly opened state for ventilation, and an aid for assisting the locking of a crescent lock. The present invention relates to a lock that can be selectively used as a lock.

[0002]

[Prior art]

 Conventionally, a sliding window or the like is generally provided with a crescent lock, which can be locked with the window / window frame body completely closed. However, depending on the season, the windows may be left open for ventilation, but in this state the Crescent lock cannot be locked and a separate lock must be installed.

Even if the crescent lock is locked, by itself, for example, a thin plate-shaped picking tool is inserted from the gap of the window frame body to rotate the sickle part, or the crescent lock is provided. There was a case in which a window was opened in a certain area, a hand was inserted from there, and the sickle was rotated, resulting in unauthorized unlocking.

[0004]

[Problems to be solved by the device]

 As mentioned above, in order to lock the window with the window slightly opened for ventilation, the crescent lock cannot be used and a separate lock must be installed. I was sometimes told.

However, in addition to the crescent lock already provided on the window frame, it is necessary to provide a ventilation lock for locking the window with the window slightly open for ventilation, and to additionally provide an auxiliary lock for the crescent lock. It is necessary to make holes for mounting on the frame, so it takes time and effort to mount the frame, and the cost is high. Even if it increases safety, it is not good to attach three or more locks, including the crescent lock, to one window.

The present invention solves the problems of the above-mentioned conventional locks used for sliding windows and the like. In other words, the object of the present invention is to slide a window that can be locked with the window slightly opened for ventilation, can also be used as an auxiliary lock for the crescent lock, and can easily open the window large. To provide a lock.

[0007]

[Means for Solving the Problems]

 A lock such as a sliding window according to the present invention comprises a horizontally-long locking main plate 1 and a cylinder lock portion 2,

The latching main plate 1 has a serrated portion 3 having a large number of serrated teeth 4 from one side toward the other side at a lower edge portion in a horizontally long vertical state, and an outer side on the other side portion. Forming a seat portion 6 for attaching to the window frame body 5 of

The cylinder lock portion 2 is slidably fitted along the saw-shaped portion 3 of the locking main plate 1, and the cylinder lock portion 2 extends toward the tip of the locking main plate 1 of the cylinder lock portion 2. A locking piece 7 that elastically meshes with the serrated tooth 4 is provided so that the sliding of the locking piece 7 can be locked. Forming a cam portion 10 for forcibly releasing

In addition, the side surface 11 of the locking main plate 1 on the side of the mounting seat portion 6 of the cylinder lock portion 2 abuts on the side surface of the vertical frame portion 12b near the center of the inner window frame body 12. The buffer plate 13 for use is attached.

In the above-mentioned structure, the serrated teeth 4 of the serrated portion 3 are attached because the cylinder locking portion 2 locks the movement of the locking main plate 1 toward the tip end side with the locking piece 7. It goes without saying that it is inclined toward the seat 6 side. In the figure, 14 is a mounting screw hole, 15 is a mounting screw, and 16 is a back plate.

[0012]

[Action]

 a) First, when a lock such as a sliding window according to the present invention (hereinafter referred to as a main lock) is attached to the window frame body 5, the latch main plate 1 is horizontally long so that the serrated portion 3 is the lower edge. In a vertical shape, corresponding to the mounting screw hole 14 of the mounting seat portion 6 on one side thereof, a female screw is provided at a position close to the central vertical frame portion 5b in the lower frame portion 5a of the outer window frame body 5. A hole (not shown) is formed.

Then, by screwing the mounting screw 15 from the mounting screw hole 14 into the female screw hole, the hooking main plate 1 is attached to the lower frame portion 5 a of the outer window frame body 5 in a serrated portion. Fix in a vertically long shape with 3 being the lower edge. After that, the cylinder lock portion 2 may be slidably engaged with the serrated portion 3 of the retaining main plate 1 from the side end portion (see FIG. 1). The attachment of the above-mentioned latching main plate 1 is the same whether it is used as a ventilation lock or an auxiliary lock.

B) When this lock is used as a ventilation lock (see FIG. 4), the window frame body 12 on the inner side of the sliding window is left open at an interval necessary for ventilation, In that state, the cylinder lock portion 2 is slid along the serrated portion 3 of the main plate 1 for latching toward the mounting seat portion 6. When the cylinder lock portion 2 slides in this direction, the locking piece 7 is in a state of being along the inclined surface of the serrated teeth 4 and is not locked and can be freely slid.

Then, the buffer plate 13 attached to the side surface of the cylinder lock portion 2 is brought into contact with the vertical frame portion 15b of the inner window frame body 15, and the duplicate key 9 may be removed. This causes the locking piece 7 in the cylinder lock part 2 to mesh with the serrated teeth 4 of the saw-shaped part 3 due to its elasticity (see FIG. 2), and the cylinder lock part 2 slides in the opposite direction. The movement, that is, the sliding of the locking main plate 1 from the mounting seat 6 side to the tip side is locked.

Therefore, even if the inner window frame body 12 is to be opened further, the cylinder lock portion 2 which is in contact with the window frame body 12 is moved by the engagement of the serrated teeth 4 of the locking piece 7. As long as it is blocked, the inner window frame body 12 cannot slide in the opening direction. This means that the windows could be locked in a state where the windows could not be opened beyond the ventilation interval set earlier.

C) Next, when this lock is used as an auxiliary lock for the crescent lock (see FIG. 5), all the sliding windows are closed, and the crescent lock is locked in that state. The cylinder lock portion 2 of the lock is slid to the mounting seat portion 6 side along the serrated portion 3 of the locking main plate 1 to the full, and the cushion plate 13 on the side surface of the cylinder lock portion 2 is attached to the inner window frame. The key 9 may be removed by bringing the vertical frame portion 15b of the body 15 into contact with the vertical frame portion 15b.

As a result, the locking piece 7 in the cylinder lock portion 2 is elastically engaged with the serrated teeth 4 of the saw-like portion 3 of the locking main plate 1 in the same manner as described above, and the cylinder lock portion 2 is locked. The sliding of the main plate 1 from the mounting seat 6 side to the tip side is stopped.

Therefore, even if an attempt is made to slide the inner window in the opening direction, the cylinder lock portion 2 that is in contact with the vertical frame portion 12b of the inner window frame body 12 cannot slide, so that the window frame body 12 is moved. It cannot be opened and the window can be locked separately from the crescent lock and will function as an auxiliary lock.

D) When the present lock has been used as the above-mentioned ventilation lock or auxiliary lock and is to be unlocked, the master key 9 is inserted into the cylinder lock portion 2 and the rotor portion 8 is rotated, and the lock portion is integrated with it. The locking piece 7 engaged with the serrated tooth 4 of the serrated portion 3 may be disengaged from the serrated tooth 4 against the elasticity by the cam portion 10. As a result, the cylinder lock portion 2 can slide along the serrated portion 3 toward the tip end side of the latching main plate 1, and thus does not act as a ventilation lock or an auxiliary lock and is unlocked. .

E) When it is desired to open the window with the lock attached (see FIG. 6), the lock key 7 is used to unlock the lock piece 7 as in the above unlocking operation. The cylinder lock portion 2 may be slid along the serrated portion 3 toward the front end portion side of the latch main plate 1 and removed. As a result, the window frame bodies 5 and 12 are not locked by the cylinder lock portion 2, so that the window can be opened wide without any trouble.

[0022]

【Example】

 1 to 6 show an embodiment of a lock such as a sliding window according to the present invention, which is composed of a horizontally-long locking main plate 1 and a cylinder lock portion 2.

The latching main plate 1 has a saw-shaped portion 3 having a large number of saw-teeth 4 at a lower edge portion in a horizontally long vertical state, from a tip portion to a portion near the mounting seat portion 6 on the other side. Further, a mounting seat portion 6 is formed on the other side through a rearward step portion, and two mounting screw holes 14 are formed in the mounting seat portion 6. The mounting seat portion 6 is for fixing the latching main plate 1 in a horizontally long vertical shape at a position closer to the vertical frame portion 5b in the lower frame portion 5a of the outer window frame body 5.

The cylinder lock portion 2 is formed by inserting the saw-like portion 3 of the latching main plate 1 into the gap formed between the cylinder lock portion 2 and the back plate 16 so that the cylinder lock portion 2 extends along the saw-like portion 3. It is slidable to all sides.

Further, in the rear portion of the cylinder lock portion 2, the cylinder lock portion 2 can lock the sliding to the front end side of the locking main plate 1 and meshes with the serrated teeth 4 by its own elasticity. A locking piece 7 is provided. Further, a cam portion 10 for forcibly releasing the engagement of the locking piece 7 with the serrated teeth 4 is formed on the rotor portion 8 which can be rotated by the compound key 9.

The side surface 11 of the locking main plate 1 on the side of the mounting seat portion 6 of the cylinder lock portion 2 is for abutting contact with the side surface of the central vertical frame portion 12 b of the inner window frame body 12. A shock-absorbing plate 13 made of synthetic rubber is attached.

In the saw-shaped portion 3, the cylinder lock portion 2 is for locking the movement of the locking main plate 1 toward the tip end side by the locking piece 7, so that the serrated teeth 4 are for mounting. Of course, it is inclined toward the seat portion 6 side. In the figure, 15 indicates mounting screws.

This lock, whether it is used as a ventilation lock or an auxiliary lock, is attached at a lower frame portion 5a of the outer window frame body 5 near the central vertical frame portion 5b. Both locks can be selectively used as long as they are attached to.

[0029]

[Effect of device]

 As is clear from the above, this lock can be used as a sliding window lock, etc., as a ventilation lock that is locked in a slightly opened state for ventilation, and can be used as an auxiliary lock for the Crescent lock with the window closed. It is also possible to open the window completely and easily.

That is, a crescent lock generally provided on a sliding window or the like can be locked with the window completely closed, and cannot be locked with the window slightly opened. In addition, the crescent lock alone could be unlocked relatively easily. However, providing ventilation locks and auxiliary locks in addition to crescent locks requires holes for mounting around the window frame, which requires time and effort for construction. In addition, it is not good to attach three or more locks, including the crescent lock.

On the other hand, this lock can be used as a ventilation lock because it can be locked even when the window is slightly open, and it can be locked even when the window is completely closed. It can also be used as an auxiliary lock. Furthermore, even if the lock is installed once, the cylinder lock part can be pulled out with a duplicate key to fully open the sash window. By providing one lock, the lock can be selectively used and is highly practical. It's a thing. .
