[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door tightening confirmation device capable of remotely confirming door tightening such as sliding windows.

[0002]

2. Description of the Related Art Generally, when going out of a house, it is necessary to check whether the shoji of each window (for example, a sliding window) is completely closed or locked (crescent). It is troublesome and complicated to check. In particular, if the number of windows is large or it is not a one-story house, it will take much more time to check.

Therefore, recently, as a part of home automation, a device (window closed state confirmation device) capable of confirming whether each window is closed at the entrance or living room without going to each window has been put into practical use. .. Further, a device for checking whether the crescent is in a locked state (locked state confirmation device) has been proposed.

Conventionally, as a window closed state confirmation device, a magnet is provided on the shoji side of the window, and a reed switch is provided on the frame side. Whether the window is open or closed by the cooperation of the magnet and the reed switch. What to detect is known.

As a lock state checking device for a lock (crescent), a device using electromagnetic waves and a device for mechanically checking the locked state by a sensor such as a limit switch have been proposed.

[0006]

Since the conventional window closed state checking device detects only the closed state of the window, it cannot confirm the locked state of the crescent, which is a problem in crime prevention. Therefore, it is conceivable to install the window closed state confirmation device and the lock state confirmation device together with each window.
However, the conventional locking state confirmation device has the disadvantages that the electronic circuit is complicated and expensive, and that the window frame (sash) structure and the mechanical mechanism are complicated, which makes manufacturing and maintenance difficult.

In view of the above circumstances, an object of the present invention is to simplify the structure, reduce the cost, improve the easiness of maintenance, and surely confirm the door tightening state from a remote position. To provide.

[0009]

According to the present invention having the above-described structure, when both shoji screens are in the open state (including the case where one shoji screen is in the open state), the handle lock mechanism works and the handle cannot be rotated in the locking direction. When both the shoji screens are closed, the closed state detecting means operates to generate a mechanical or electrical trigger signal. The lock release means automatically releases the handle lock mechanism by this trigger signal. For the first time, the handle can be rotated and locked.

As described above, the present crescent provided with the above-mentioned handle lock mechanism can be locked only when the shoji (window) is completely closed, and the present invention is the locking operation of the crescent. Use to confirm the door lock state of the shoji (window).

That is, the posture of the reflecting surface is changed and positioned at a predetermined position in accordance with the rotation of the crescent handle in the locking direction. The change in the attitude of the reflecting surface is detected by the detecting means.

The confirming means judges the door tightening state based on the detection result of the detecting means and notifies the judgment result through the notifying means. That is, when the detecting means detects that the reflecting surface is positioned at a predetermined position, the confirming means determines that the door is completely locked (the shoji is closed and the crescent is locked). Then, the judgment result (complete door tightening) is notified through the notification means. Further, when the detecting means detects that the reflecting surface is not positioned at the predetermined position,
The confirmation means determines that the door locking is incomplete, and notifies the determination result (incomplete door locking) via the notification means.

As described above, the present invention uses the crescent that can be locked only when the shoji (window) is completely closed, and uses the reflecting mirror and the detection means to determine whether the crescent is in the locked state. Since the confirmation means notifies the door lock state via the notification means based on the detection result, it is easy to reduce the cost and improve the maintainability. Can be achieved.
Further, since the reflective surface is provided on the handle, it can be easily cleaned and repaired, and the door lock state of the shoji (window) can be surely confirmed remotely from the notification means.

Therefore, the structure can be simplified, the cost can be reduced and the easiness of maintenance can be improved, and the door lock state of the shoji (window) can be surely confirmed remotely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The door tightening confirmation device according to the present embodiment is applied to a sliding window 9 having an inner shoji 1 and an outer shoji 5, as shown in FIG. 2, and the chain is locked only when the shoji 1 and 5 are completely closed. The lockable state (the open / closed state of the window 9 and the locked state of the crescent 10) is confirmed by using the crescent 10 which can be applied.

Specifically, as shown in FIG. 2 and FIG. 9, the present door tightening confirmation device is provided on the crescent 10 and the handle 21 of the crescent 10, and the posture is determined according to the rotation of the handle 21 in the locking direction. A reflecting surface (61) for changing the angle, a detecting means 65 for detecting the posture of the reflecting surface (61), a door closing state based on the detection result of the detecting means 65, and a notifying means (91) for the determination result. Confirmation means (8)
1) and are included.

Here, the crescent 10 is provided with a handle lock mechanism, a closed state detecting means, and a lock releasing means, and as shown in FIG. 4, the handle 21 is chained only when both the shoji 1 and 5 are completely closed. It is formed so that it can be rotated in the locking direction to engage with the locking member 51 on the side of the shoji screen 5 for locking.

First, a general configuration of the crescent 10 and the like will be described with reference to FIGS. 3 and 4. The crescent 10 includes a main body 11 fixed to the inner shoji 1 and a handle 21 (grip portion 22, hook portion 2) rotatably attached to the main body 11.
3) and is fixed to the vertical frame 2 of the inner shoji 1 (glass 3).

On the other hand, a locking member 51 is fixed to the vertical frame 6 of the shoji screen 5 (glass 7) in correspondence with the crescent 10 as shown in FIG. This locking member 51 is shown in FIG.
As shown in FIG. 5, a base end portion 53 for fixing to the vertical frame 6 provided on the left side of the plate 52, a locking portion 54 engageable with the hook portion 23 of the handle 21, and a closed state detecting means described later. And a detection plate 55 that is inclined and forms a part. Therefore, the both doors 1 and 5 are closed as shown in FIG. 4, and the handle 21 (grip portion 22) is rotated to engage the hook portion 23 with the locking portion 54, whereby locking can be achieved. Also,
It can be unlocked by separating both 23 and 54.

However, in the above structure, the handle 2 is irrespective of the open / closed state of the shoji 1 and 5 as in the conventional crescent.
1 can be rotated in the locking direction, and the crescent 10 can be locked even when the shoji screens 1 and 5 are in the half-opened state, and the purpose (that is, confirmation of door locking using the crescent 10) cannot be achieved. ..

Therefore, in the present invention, the handle lock mechanism, the closed state detecting means and the unlocking means are provided so that the crescent 10 can be locked only when the shoji 1 and 5 are completely closed.

That is, the handle lock mechanism of the handle 21 is provided when both the shoji screens 1 and 5 are in the open state (including the case where one shoji screen is in the open state. The same applies hereinafter), that is, when the shovel is not completely closed. This is to negate the rotation operation in the locking direction, that is, to make it impossible, and comprises the vertically movable plate 31, the sliding piece 42 and the spring 43 shown in FIG. Further, the closed state detecting means includes the trigger pin 45 integrated with the sliding piece 42 provided on the crescent 10 (main body 11) side, the detection plate 55 integrated with the locking member 51, and the spring 43. That is, in this embodiment, the crescent 10 and the locking member 51 are
It is formed to mechanically and automatically detect the completely closed state of both shoji 1 and 5 via and. Of course, other mechanical, electrical and electronic configurations may be used.

On the other hand, the lock releasing means automatically releases the handle lock mechanism (31, 42, 43) when the trigger pin 45 is displaced, that is, when the trigger signal is output. The movable plate 31, the sliding piece 42, and the spring 43 are formed. In other words, in this embodiment, the handle lock mechanism, the closed state detecting means, and the unlocking means have a skillful organic and integrated structure in which the components also serve as the respective components, thereby achieving downsizing and cost reduction.

Hereinafter, such components will be described in detail with reference to FIGS. In FIG. 5, the main body 11 includes bolt holes 11A and 11A for fixing the inner shoji 1 and a stop pin 25.
Hole 12h for inserting and square hole 12H for guiding the sliding piece 42
And a space for accommodating the cam body 15, the vertically movable plate 31 and the like are formed inside.

The handle 21 has a pin hole 24 (key groove 24
The pin 25 (key 26, small-diameter portion 27, corner portion 28) is inserted into A) and is rotatably attached to the main body 11. Reference numeral 12 is a pair of leaf springs that apply a certain resistance to the handle 21, and the plate 13 with the hole 14 is the leaf spring 12
To guide. The cam body 15 having the pin 17 has a square hole 1
By inserting the corner portion 28 of the pin 25 into the pin 6, the handle 21 is rotated to be rotated by the same angle as the handle 21. The pin 17 is fitted in the horizontal groove 33 of the vertically movable plate 31 and the circular arc groove 36 of the guide plate 35. Note that 38 and 38 are holes for fixing bolts to the main body 11.

Therefore, the handle 21, the cam body 15,
The upper and lower movable plates 31, the guide plate 35, etc. are attached to the main body 11
When the handle 21 is rotated counterclockwise (locking direction) in FIG.
The pin 17 is guided by the arc groove 36 and rotates together with the handle 21. Then, since the pin 17 is fitted in the horizontal groove 33, the vertically movable plate 31 moves up and down as the cam body 15 rotates.

Here, in order to negate the pivoting operation of the handle 21 in the locking direction, the downward movement of the vertically movable plate 31 may be prevented. That is, in this embodiment, the upper and lower movable plates 31 are formed so as to contact the upper surface 42U of the sliding piece 42 biased in the protruding direction by the spring 43 in a normal state (both shoji 1, 5 are open). .. That is, as shown in FIG. 6, the handle lock mechanism (31, 42, 43) is configured.

Next, when the shoji 1 and 5 are closed from the state shown in FIG. 3 to the state shown in FIG. 4, the trigger pin 45 abuts against the detection plate 55 integral with the locking member 51 and the urging force of the spring 43. It is moved so as to push the sliding piece 42 back into the main body 11 against. That is, it is understood that the detection plate 55 and the trigger pin 45 cooperate with each other to automatically detect the closed state of both the sliding doors 1 and 5 based on the pushing displacement amount of the trigger pin 45.
That is, the closed state detection means (45, 55) is formed,
A trigger signal (displacement of the trigger pin 45) is output.

In this way, when the trigger signal is generated, the sliding piece 42 is pushed into the main body 11 against the biasing force of the spring 43, as shown in FIG. At this time, the relative positional relationship between the vertically movable plate 31 and the sliding piece 42 is such that the lower end portion 32D of the vertically movable plate 31 is located outside the sliding piece 42 as shown in FIG. Further, the vertical movable plate 31 is provided with a vertical groove 34 having a width dimension larger than the diameter of the trigger pin 45.

Therefore, in the state shown in FIG. 7 in which the sliding piece 42 is pushed into the main body 11 by the trigger signal, the handle lock mechanism is automatically released, and if the handle 21 is rotated in this state. Can be locked. That is,
It is understood that the up-and-down movable plate 31, the sliding piece 42, and the spring 43 constitute lock releasing means.

Here, as shown in FIG. 3, consider a case where both the shoji 1 and 5 are in the released state. In this state, since the trigger pin 45 is free, the sliding piece 42 is projected in the main body 11 by the urging force of the spring 43 and is in the state shown in FIG. The lower end 32D of the vertically movable plate 31 has a sliding piece 42.
The position is constrained to (upper surface 42U). That is, the handle lock mechanism works. Therefore, it is impossible to rotate the handle 21 in the counterclockwise direction, that is, the locking direction in FIG. Therefore, it is possible to completely prevent the erroneous operation of operating the handle 21 itself to lock the doors 1 and 5 in the open state and the incomplete closure.

Next, when the two shoji screens 1 and 5 are completely closed as shown in FIG. 4, the inner shoji screen 1 forms a closed state detecting means.
The trigger pin 45 on the side contacts the detection plate 55 on the side of the shoji screen 5 and is pressed by the pressing force F shown in FIG.
Is pushed in the X direction against the biasing force of the spring 43. That is, the trigger signal is generated by the displacement of the trigger pin 45.

When this trigger signal is output, the sliding piece 42 (upper surface 42U) integral with the trigger pin 45 is shown in FIG.
As shown in, the upper and lower movable plates 31 come off from the lower end portion 32D. That is, the handle lock mechanism is automatically released.
Therefore, when the handle 21 is rotated in this state, the pin 17 of the cam body 15 is guided to the circular arc groove 36, and the vertical movable plate 31 can be lowered via the horizontal groove 33. This is because the width dimension of the vertical groove 34 is larger than the diameter of the trigger pin 45. Here, the hook portion 23 of the handle 21 can be locked by engaging the locking portion 54 of the locking member 51.

Therefore, it is possible to operate the lock with both shoji 1,5.
Only when is completely closed. In other words,
Since the locking operation can be executed only in the completely closed state, the fact that it can be executed guarantees that both the shoji screens 1 and 5 are completely closed.

Since the handle lock mechanism of the crescent 10 has a mechanical structure of the vertically movable plate 31, the sliding piece 42 and the spring 43, the structure is simple and stable operation for a long period is guaranteed.

The trigger signal of the crescent 10 is
Trigger pin 45 on the side of the internal shoji 1 and detection plate 5 on the side of the external shoji 5
It is generated by directly detecting the actual closed state of both shoji 1 and 5 by the engagement with 5, so that the malfunction is eliminated and the reliability is high.

The handle lock mechanism, the closed state detecting means, and the unlocking means of the crescent 10 are composed of the upper and lower movable plates 31, the sliding piece 42, the trigger pin 45 integrated therewith,
Since the spring 43 and the like are organically and integrally configured,
Miniaturization and cost reduction are possible, and high-speed and reliable responsiveness is demonstrated.

Further, the sliding piece 4 when the closed state is detected
Since the lock is locked by the displacement of 2, the rotation of the cam body 15 by the operation of the handle and the vertical movement of the vertically movable plate 31, the selection range of the lock detection signal generator used as the detection means of home automation can be expanded, and the size can be reduced. Etc. is also useful.

By the way, the reflecting surface is provided on the handle 21 of the crescent 10 as shown in FIGS.
The posture is changed according to the rotation of the handle 21 in the locking direction. This reflecting surface is formed so that the reflectance of the light beam emitted from the light emitting element (66) of the detecting means 65 is significantly higher than that of the peripheral member. In this embodiment, the reflecting surface is formed by the reflecting mirror 61 having an arcuate mirror surface. The reflecting mirror 61 is attached to a mounting portion 22a formed at the tip of the handle portion 22 of the handle 21.

The detecting means 65 has a reflecting surface (reflecting mirror 6
It is a means for detecting the posture change of 1), and is the upper frame 9U of the window 9.
The light emitting element (in this embodiment, the light emitting diode 6
6) and a light receiving element (phototransistor 67 in this embodiment). Here, the light emitting diode 66 is formed so that light can be emitted toward the reflecting mirror 61 when the inner door 1 and the outer door 5 are completely closed. On the other hand, the phototransistor 67 is provided when both the shoji screens 1 and 5 are completely closed, the handle 21 of the crescent 10 is locked, and the reflecting mirror 61 is positioned at a predetermined position (locking corresponding position) shown in FIG. Further, it is arranged so as to receive the light emitted from the light emitting diode 66 and reflected from the mirror surface of the reflecting mirror 61.

The detecting means 65 is provided with reed switches 68a, 68b and magnets 69a, 69b for more surely detecting the open / closed state of the shoji screens 1, 5. Here, the magnet 69a (69b) is
As shown in FIG. 8, the upper frame 8 (4) of the external shoji 5 (inner shoji 1)
It is attached using an adhesive. Further, the reed switches 68a and 68b are provided on the window upper frame 9U which faces the magnets 69a and 69b when both the shoji 5 and 1 are completely closed.
It is provided in the part.

Therefore, when the shoji 5, 1 are completely closed, the reed switches 68a, 68b face the magnets 69a, 69b, respectively.
It is closed by the magnetic forces of a and 69b.

By the way, the detecting means 65 is configured to be driven and controlled by the control device 81 shown in FIG.
The control device 81 has a CPU, a ROM, a RAM, etc., a light emitting diode drive circuit 82, a signal receiving circuit 83,
Reed switch input circuit 84, monitor input / output circuit 8
5. The external input / output circuit 86 is included. Specifically, the light emitting diode 66 of the detecting means 65 is configured to be driven and controlled by a light emitting diode drive circuit 82 to emit and turn off light. In addition, the phototransistor 67
When the reflected light from the reflecting mirror 61 is detected, the detection signal is received by the signal receiving circuit 83. Further, when the reed switches 68a and 68b are closed, the closing signal is input to the reed switch input circuit 84. The monitor input / output circuit 85 is connected to the display circuit 92 of the monitor device 91, the motion sensor 96, and the like. Further, the external input / output circuit 86 includes a security device 98.
(External input / output circuit 99 etc.) is connected.

Further, the confirming means is constructed so as to judge the door lock state of the window 9 (shoji 1, 5) based on the detection result of the detecting means 65 and notify the judgment result via the notifying means.
In this embodiment, the confirmation means is the control device 8 described above.
It is formed by utilizing a part of the functions of 1. The notification means is formed of the monitor device 91. The monitor device 91 is installed in a living room, an entrance, or the like (a living room in this embodiment), and has a display circuit 92, a human sensor 96, and a standby lamp 93, a screen lamp 94, and a lock lamp 95 connected to the display circuit 92. And so on.

Next, the operation of this embodiment will be described based on the flowchart shown in FIG. When a person approaches the periphery of the monitor device 91, a human sensor 96 built in the monitor device 91 sends a signal of person detection to the control device 81 (step ST10). In response to this, the control device 81
Turns on the standby lamp 93 via the display circuit 92 of the monitor device 91 (ST12). Next, when both reed switches 68a and 68b are closed, the control device 81 lights the closing door lamp 94 through the monitor input / output circuit 85, the display circuit 92, etc.
Notify that 5 is completely closed (ST14, ST
16, ST18).

The control device 81 is a monitor device 91.
The human detection signal from the
When a closing signal is input from 8a and 68b, the light emitting diode 66 is caused to emit light (ST20). At this time, if the crescent 10 is not locked, the reflecting mirror 61 is not positioned at the locking corresponding position shown in FIG. Therefore, the light emitted from the light emitting diode 66 is not incident on the reflecting mirror 61 and therefore is not incident on the phototransistor 67.

In response to this, confirmation means (control device 81)
Turns off the lock lamp 95 of the monitor device 91 to notify that the crescent 10 is not in the locked state (that is, door locking is incomplete) (ST22, 30). When the crescent 10 is locked, the reflecting mirror 61 is positioned at the position corresponding to the locking, so that the light emitted from the light emitting diode 66 and reflected by the reflecting mirror 61 is incident on the phototransistor 67 and the phototransistor 67. Is turned on (ST22). In response to this, confirmation means (8
In 1), the locking lamp 95 is turned on to notify that the crescent 10 is in the locked state (that is, the door is completely locked) (ST24).

If both reed switches 68a and 68b are not closed in step ST14, the controller 81
Turns off the shut-off lamp 94 and the lock lamp 95 of the monitor device 91 to notify that the window 9 (shoji 1, 5) is not completely locked (ST26, ST28, ST).
30).

In step ST10, the motion sensor 9 is detected.
6 does not turn on (that is, when there is no person around the monitor device 91), the reed switches 68a. When 68b is closed, the obstruction lamp 94 is turned on and the locking lamp 95 is turned off (ST32, ST34, ST36, ST3).
8, ST30). In addition, both reed switches 68a, 68
When b is not closed, both the obstruction lamp 94 and the lock lamp 95 are turned off.

According to this embodiment, however, the crescent 10 that can be locked only when the windows 9 (shoji 1, 5) are completely closed is used, and whether or not the crescent 10 is in the locked state. This is optically detected by the cooperation of the reflecting mirror 61 and the detection means 65, and the confirmation means (8
In 1), the door tightening state is notified via the notifying means (91), so that the structure is not complicated and the cost can be easily reduced. Further, since the reflecting mirror 61 is provided on the handle portion 22 of the handle 21, mirror surface cleaning and repair can be easily performed. As a result, it is possible to reliably confirm the door lock state of the window 9 (shoji 1, 5) from the remote via the notification means (91).

Therefore, the structure can be simplified, the cost can be reduced and the easiness of maintenance can be improved, and the locked state of the window 9 (shoji 1, 5) can be surely confirmed from a remote place.

Further, since the reflecting mirror 61 and the detecting means 65 can be attached to the shoji screen (1, 5) or the like, which is relatively unaffected by the shoji screen size, the applicability can be expanded. In particular, since the magnets 69a and 69b are attached to the upper frame (8, 4) of each shoji (5, 1) using an adhesive, the assembly is further facilitated.

In the above embodiment, the control device 8
1 is provided, but there are a large number of windows 9 (hence, the detecting means 65) for confirming the door lock, and each detecting means 65 is divided into several blocks depending on the arrangement relationship (for example, the first floor and the second floor). (Portion), a control device [for example, control devices 81 (A) and 81 (B) as shown in FIG. 11] may be provided for each block. This makes it possible to reduce costs without complicating the wiring. In this case, both control devices (81
A, 81B) are connected. Further, when the detection means 65 is installed in each of a plurality of rooms, a control device (not shown) may be provided in each room.

Further, the reflecting mirror is attached to the handle portion 2 of the handle 21.
The detecting means 65 is formed by the reflecting mirror 61 attached to
Has a high reflectance for the light emitting element (66) of the handle 21
If the posture is changed according to the rotation direction of the lock of
It may be formed in any way.

Further, although the notifying means is composed of the monitor device 91, any structure may be adopted as long as it can notify the door tightening state. For example, the notifying means may be configured to notify the door closing state by voice.

Further, for example, the reed switch 68 at night.
When a and 68b are opened, the warning lamp should sound (or the security device 98 should be notified).
You may comprise.

Further, although the light emitting element of the detecting means 65 is formed of the light emitting diode 66, it may be formed of other light emitting element (eg, phototube). Although the phototransistor 67 is used as the light receiving element, other known light receiving elements may be used.

Furthermore, the closed state detecting means, the unlocking means, etc. of the crescent 10 have a mechanical structure. However, these may have an electrical / electronic structure or a structure combining these with a mechanical structure. Can also be implemented. Also,
Although the trigger pin 45 has a conical shape, the shape of each constituent element including the trigger pin can be arbitrarily selected and implemented. Further, the application target is not limited to the sliding window. Furthermore, it can be implemented even if a conventional lock mechanism for locking after locking is provided.
