Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a lock confirmation device.

[Prior Art] Conventionally, a lock confirmation device described in Japanese Utility Model Laid-Open No. 62-99768 has been proposed. This lock confirmation device is provided with an actuator provided on the hinge mounting side of a shoji that opens and closes by a hinge to bias the shoji in the opening direction, a switch that interlocks with the opening and closing operation of the shoji, and an open state of the shoji connected to the switch. And a notification device for displaying the closed state.

[Problems to be Solved by the Invention] However, in the above-described conventional lock confirmation device, a complicated actuator is attached to the door frame so that it is housed in the case while being backed up by a spring, and a switch such as a limit switch is installed. It needs to be attached to the door frame. Therefore, the structure of the device itself and the structure for attaching it to the door frame are complicated.

Further, the conventional lock confirmation device can be applied only to hinged doors having hinges, and cannot be applied to sliding doors.

An object of the present invention is to make it possible to confirm locking of a door in various forms with a locking confirmation device having a simple structure as well as a mounting structure.

[Means for Solving Problems] The present invention provides a lock confirmation device for locking a door housed in an opening frame of a building by engaging a first engaging member and a second engaging member. , Elasticity that is compressed between the door and the opening frame when the door is closed and elastically deforms to become a packing between the door and the opening frame, and also has a switching element that is turned on / off by the deforming operation. A body is provided with the door on at least one of the opening frames, and has a locking determination means for determining locking based on the ON / OFF state of the switching element.

[Operation] When the door is opened and the first engagement member and the second engagement member are not engaged with each other in the unlocked state, the switching element included in the elastic body is in an unlocked equivalent state (for example, Off state).

Further, in the unlocked state in which the first engaging member and the second engaging member are not engaged even when the door is closed, the elastic body is temporarily provided between the opening frame and the opening frame as the door is closed. Although it is elastically deformed by being squeezed, it immediately pushes the door back to the open side with a resilient recovery habit. Therefore, as a result, the switching element included in the elastic body forms the same unlocking state (for example, the off state) as described above.

In the locked state in which the door is closed and the first engaging member and the second engaging member are engaged with each other, deformation of the elastic body that is pinched between the opening frame and the door is closed. The state is continuously maintained. Therefore, the ON / OFF state of the switching element included in the elastic body is switched from the above state in association with the deformation operation of the elastic body, and a lock-equivalent state (for example, an ON state) is formed.

Therefore, the lock determination means determines the lock when the door is closed and locked by the ON / OFF states of the switching elements (1) to (4), and unlocks otherwise.

Therefore, according to the present invention, the locking determination data can be collected only by providing the elastic body having the switching element on at least one of the door and the opening frame. Therefore, it is possible to confirm the locking of the door in various forms with the locking confirmation device having a simple structure as well as a mounting structure.

[Embodiment] FIG. 1 is a sectional view showing a main part of a sliding door to which a locking confirmation device of the present invention is applied, FIG. 2 is a perspective view showing a locking portion of the sliding door, and FIG. 3 is a locking confirmation. FIG. 4 is a block diagram showing an example of an electric circuit of the device, and FIG. 4 is a free state of the elastic body (a state corresponding to unlocking).
5 is a schematic view showing another structural example of the elastic body, FIG. 6 is a front view showing a building to which the present invention is applied partially broken, and FIG. 7 is a lock of the present invention. It is sectional drawing which shows the principal part of the hinged door to which the confirmation apparatus was applied.

As shown in FIG. 6, the building 10 has four sliding doors 12 housed in a window opening frame 11 and a display panel 13 of a home security system provided in the room.

Two sliding doors 12A and 12B adjacent to each other in the left half area and the right half area of the window opening frame 11 are locked by a crescent lock 14. As shown in FIG. 2, the crescent lock 14 includes a rotary engagement member (first engagement member) 16 rotatably supported by a frame member 15A of one sliding door 12A and the other pulling lock. Fixed engaging member (second engaging member) fixed to the frame member 15B of the door 12B 1
It is configured to have 7 and.

When the crescent lock 14 is locked, the two sliding doors 12A, 12A adjacent to each other in the center of the opening frame 11 are butted against each other. Further, at this time, as the rotary engagement member 16 of the crescent lock 14 is rotated deeper in the engagement direction with the fixed engagement member 17, the fixed engagement member 18 is formed by the inclined engagement surface 18 thereof.
17 is pushed in the closing direction of the sliding door 12. As a result, the two sliding doors 12B on both the left and right sides are pressed against the vertical frame 19 side of the opening frame 11 when the crescent lock 14 is locked.

Here, at least one of the left and right vertical frames 19 of the opening frame 11,
An elastic body 20 as shown in FIGS. 1 and 4 is fixed by adhesion or the like to a portion where the sliding door 12 abuts when the sliding door 12 is closed. The elastic body 20 is formed by integrally molding a base portion 21 made of insulating rubber (for example, EPDM) and a switching element 22 made of conductive rubber (for example, a mixture of EPDM and conductive carbon). However, in the practice of the present invention, the elastic body and the switching element need not be integrally molded. The elastic body 20 can elastically compressively deform in a direction in which the pair of switching elements 22 are in contact with each other, and separate the pair of switching elements 22 in a free state. That is, the elastic body 20 is configured such that when the sliding door 12 is closed, the sliding door 12 and the opening frame 11 are closed.
It is elastically deformed by being pinched between them and the switching element 22 is turned on / off by the deformation operation.

Further, a transmission device 23 is fixed to a portion of the opening frame 11 near the elastic body 20. As shown in FIG. 3, the transmitter 23 has a power supply 24 and a transmitter 25, and is coded into a code specific to the opening frame 11 under the condition that the switching element 22 of the elastic body 20 is turned on. Outputs locking radio signal.

On the other hand, the display panel 15 of the home security system is the receiving unit.
26, a CPU (locking determination means) 27, and a display unit 28 are incorporated. The receiver 26 wirelessly receives the locking radio signal. The CPU 27 includes a serial-parallel conversion unit 29 and a comparison unit 3
0, a code signal storage unit 31, a control unit 32, an output unit 33. The conversion unit 29 encodes the reception signal received by the reception unit 26 and converts it into a reception code signal P. On the other hand, the code signal storage unit 31 presets and stores each code signal Q corresponding to each opening frame or each room of the building 10. Comparison unit 30
Compares the received code signal P with the stored code signal Q,
The comparison result is transmitted to the control unit 32. The control unit 32 identifies which opening frame or room door the received code signal P corresponds to, and determines whether the door is locked in each opening frame. This determination information is transferred from the output unit 33 to the display unit 28, and the locked state of each door is displayed on the display unit 28.

Next, the operation of the above embodiment will be described.

When the sliding door 12 is opened and the pivotal engagement member 16 and the fixed engagement member 17 are not engaged with each other in the unlocked state, the switching element 22 included in the elastic body 20 is in the unlocked equivalent state ( Off state).

Further, in the unlocked state in which the rotary engagement member 16 and the fixed engagement member 17 are not engaged even if the sliding door 12 is closed, the elastic body 20 is temporarily closed when the sliding door 12 is closed. Opening frame 11
Although it is elastically deformed by being pinched between and, immediately after that, the sliding door 12 is pushed back to the opening side by elastic recovery habit. Therefore, the switching element 22 included in the elastic body 20
As a result, the same unlocking state (off state) as described above is formed.

In the locked state where the sliding door 12 is closed and the rotary engaging member 16 and the fixed engaging member 17 are engaged with each other, when the sliding door 12 is closed, a pinching force is applied between the sliding door 12 and the opening frame 11. The deformed state of the elastic body 20 thus maintained is continuously maintained. Therefore, the on / off state of the switching element 22 included in the elastic body 20 is switched from the above state in association with the deformed state of the elastic body 20 to form a locking equivalent state (on state).

Therefore, the CPU (locking determination means) 27 determines whether the sliding door 22 is turned on or off depending on the ON / OFF states of the switching elements 22.
When 12 is closed and locked, it is judged to be locked, otherwise it is judged to be unlocked.

Thus, according to the above embodiment, the sliding door 12 and the opening frame 11
The locking determination data can be collected only by providing the elastic body 20 including the switching element 22 on at least one of the above. Therefore, the locking of the sliding door 12 can be confirmed by the locking confirmation device having a simple structure as well as a mounting structure.

Further, according to the above embodiment, even when the opening frame 11 is provided with two or more crescent locks 14, a single switching element 22 is used.
Can confirm the locking of all Crescent tablets 14.

Further, in the above-mentioned embodiment, the elastic body 20 can also function as a packing between the opening frame 11 and the sliding door 12 by being provided over the entire length above and below the vertical frame 19 in the opening frame 11. However, in the practice of the present invention, the elastic body may be provided on at least one of the door and the opening frame, and may be provided only on a part in the vertical direction.

Further, the elastic body used in the embodiment of the present invention, like the elastic body 40 shown in FIG. 5, turns on the pair of switching elements 41 in the unlocking equivalent state (free state) and locks corresponding state (deformed state). ), The pair of switching elements 41 may be turned off.

Further, the lock confirmation device of the present invention can also be applied to an entrance lock as shown in FIG. In the figure, 51 is a door frame, 52 is a door, 53 is a dead bolt (first engaging member), 54 is a recess (second engaging member), and 55 is substantially the same elasticity as the elastic body 20. It is the body.

Further, in the implementation of the present invention, the output signal of the wireless transmission device is not limited to the radio wave signal and may be an infrared signal or the like.

In addition, a lithium battery, a solar battery, or the like is used as a power source of the wireless transmission device.

Further, in the implementation of the present invention, the state of the switching element may be transferred to the lock determination means by wire.

Further, according to the present invention, not only can the door lock be confirmed, but also the occurrence of a crime can be prevented by issuing an alarm sound when an intruder breaks the glass screen or the like to open the crescent lock or the like.

[Effects of the Invention] As described above, according to the present invention, it is possible to confirm the locking of a door in various forms with a locking confirmation device having a simple structure and mounting structure.
