Description

[Detailed description of the device] [Industrial applications]

The present invention is mainly used by being attached to a horizontal frame of a sliding window and serves as an auxiliary lock.
The present invention relates to an auxiliary lock with an alarm that emits an alarm sound when a window is opened in a locked state.

[Prior art]

Conventionally, there have been many proposals other than the idea of Japanese Utility Model Publication No. 56-29492 as an auxiliary lock for a sliding window formed by rotatably attaching a locking body to an attachment plate. In addition, as a device having auxiliary lock means and alarm means
No. 59-104290 device is proposed.

[Problems to be solved by the device]

In the former conventional example, since there is no alarm means, it is not possible to intimidate the bandits, and it is delayed for the family members to detect the invasion of bandits, and there is a problem that a sufficient crime prevention effect cannot be obtained. there were. Further, in the latter conventional example, the upper hook and the lower hook are spread and installed between the window frame and the window mounting frame to serve as an auxiliary lock, which must be removed each time the window is opened. However, there is a problem that the operation is troublesome. In addition, the main body has a built-in reed switch, and a magnet is attached to the window glass.If the window frame just touches the main body, no alarm will be issued, and the window will be opened so that bandits can enter. Since the main body comes off and an alarm is issued by the reed switch after that, there is a problem that it is easy to allow a bandit to enter, and the discovery of a family member is delayed. Further, in this type of auxiliary lock with alarm, no consideration was given to battery replacement.

[Means for Solving the Problems]

In order to solve the above problems, the present invention provides an auxiliary lock with an alarm in which a locking body is rotatably attached to an attachment plate, and the locking body has a sounding body that emits an alarm sound. A switch for ringing the sounding body is provided on one side, an insertion hole is formed in the peripheral surface, and a button-type battery supported by a holder is removably inserted into the insertion hole. is there.

[Action]

The present invention is constructed as described above, and in order to use it, the attachment plate (2) is attached to the outer frame (13) of the outer glass door (13).
It may be attached to a) with an adhesive tape (8) or screws.
The position of attachment to the horizontal frame (13a) is the vertical frame (14a) of the glass door (14) with the tip of the locking body (1) inside when the window is closed.
May be in contact with each other, or may be in a slightly separated position as shown in FIG. In the case of the position shown in FIG. 1, the window can be locked with the window slightly opened. When unlocked, the lock body (1) is placed upright as shown in FIG. 2 [A]. Further, in order to bring it into the locked state, as shown in FIG. 2 [B], the locked body (1) is tilted to be in a horizontal state. When trying to open the window in this state, the vertical frame (14a) of the inner glass door (14) abuts against the tip of the lock body (1) and cannot be opened, and the switch (4) provided at the tip Is pressed and the sounding body (5) sounds. When replacing the battery, pull the end of the holder (12) to take out the button battery (11) and replace it.

【Example】

Next, an embodiment of the present invention will be described with reference to the drawings. According to the present invention, a lock body (1) and an attachment plate (2) are pivotally and detachably attached by a shaft (6). When the lock body (1) and the attachment plate (2) are detachably and pivotally attached to each other, the glass door on the right side when viewed from the inside is outside (the above-mentioned

If the locking body (1) is removed and the lock body is pivoted to the left and right, the explanation can be made in the opposite case. Inside the lock body (1), a sounding body (5) such as a piezoelectric buzzer, a control circuit (not shown) for controlling the sounding of the sounding body (5), and a battery (11) as a power source of the control circuit. Is housed, a switch (4) for ringing the sounding body (5) is provided so as to project from the tip, and an inclined notch (3) is provided at the rear end. When the present invention is attached to the horizontal frame (13a) of the glass door (13), the outer glass door to which the lock body (1) is attached is in a state where the lock body (1) is upright (unlocked state). (13)
And between the inner glass door (14) that abuts the lock body (1), the lock body (1) falls down and abuts the glass surface of the inner glass door (14) due to some shock ( (See Fig. 4), if the glass door (14) or (13) is closed, the inside of the vertical frame (14a) abuts against the inclined notch (3) at the rear end of the locking body (1), and the locking body ( A force is exerted in the direction causing (1), and it can be closed as usual. The attachment plate (2) is provided with screw holes (7) (7) for attachment and an adhesive tape (8) is attached to the back surface. The reference numeral (9) is a cushioning material such as rubber, which absorbs a shock when the glass door (14) collides. A battery insertion hole (10) is formed on the upper surface of the lock body (1), and the button type battery (11) supported by the holder (12) is inserted therein. . The battery insertion hole (10) may be provided on the circumferential surface of the lock body (1), that is, on the upper surface as well as on both side surfaces or the lower surface. The sounding body (5), once the switch (4) is turned on,
The alarm sounds intermittently every 1 second and stops after 30 seconds. Further, the intermittent cycle of the alarm sound may be gradually increased. Various structures are conceivable for maintaining the lock body (1) in the upright state and the horizontal state, and any structure may be adopted.

[Effect of device]

As described above, according to the present invention, it is possible to lock the glass door with the glass door slightly open, and if a bandit tries to enter from there and further opens the glass door, a switch is pressed and an alarm sound is immediately issued. Since it will be emitted, you can threaten and repel the bandits before the glass door opens so that the bandits can intrude, and the family members can swiftly cope with illegal intrusion, so keep the glass door open with confidence. There is an extremely excellent effect that Further, the present invention has an advantage that the above-mentioned high crime prevention effect can be obtained by a simple operation, since the locking and unlocking can be performed only by rotating the locking body. Furthermore, since the insertion hole is formed in the peripheral surface of the locking body and the button type battery supported by the holder is removably inserted in the insertion hole, the battery can be replaced very easily.
There is an effect that the locking body can be made thin.
