Description

  The present invention is provided between a pair of relatively openable and closable opening / closing member structures constituting an opening / closing member installed in an opening of a building, and detects a relative positional relationship between these opening / closing member structures. The present invention relates to an open / close member state detection apparatus.

The entrance of the building, the sweep-out, or the opening such as a window can be opened and closed by an opening / closing member such as a door or a glass door.
In some cases, it is impossible to visually confirm whether these open / close members are in an open state or a closed state, or whether they are locked or unlocked.

  In order to deal with such problems, conventionally, for example, as shown in Patent Document 1, a permanent magnet is attached to a locking knob that is provided on a door and is rotated, and the surface of the door in the vicinity thereof is mounted.

  On the other hand, since the opening / closing member is installed so as to be relatively movable with respect to the building, detection devices such as the locking knob and magnetic sensor provided integrally with the opening / closing member are also provided independently of the building. There must be.

  Various devices and a power source are necessary to process the detection signal from the magnetic sensor, and these are also required to be integrated with the magnetic sensor, so these are incorporated in one casing.

  Further, when detecting a change in magnetic force accompanying the rotation of the permanent magnet, it is necessary to position the magnetic sensor as close as possible to the locking knob in order to ensure the detection accuracy.

Thus, in order to bring the magnetic sensor close to the locking knob, the magnetic sensor must be incorporated near the end face of the casing.
Further, it is desirable that the magnetic sensor be installed in a predetermined posture with respect to the magnetic field lines of the permanent magnet in order to ensure the operation thereof.

  If the magnetic sensor is incorporated into the casing under such conditions, the positional relationship between them is also fixed.

  By the way, the shape of the opening / closing member of the building varies depending on the position of the building and the application of the opening, and the installation position of the above-described casing with a built-in magnetic sensor may be limited.

  When the installation position of the casing is limited in this way, the positional relationship between the built-in magnetic sensor and the locking knob is also limited, so the magnetic sensor is optimal for magnetic detection with respect to the locking knob. It is assumed that it will not be possible to install in such a state that the versatility is narrowed.

  The present invention has been made as a solution to such problems remaining in the prior art, and between a pair of opening and closing member structures installed in an opening of a building so that the opening can be opened and closed. When detecting the relative positional relationship using a permanent magnet and magnetic detection means, it is possible to detect magnetic changes effectively even when the installation position of the magnetic detection means is limited. Thus, it is an object to be solved to provide a state detecting device for an opening / closing member capable of enhancing the versatility.

  In order to solve the above-described problems, the state detection device for an opening / closing member according to the present invention is provided between a pair of opening / closing member structures that constitute an opening / closing member that is installed in an opening of a building and that is relatively movable. An opening / closing member state detecting device for detecting a relative positional relationship between the opening / closing member constituting body and a permanent magnet attached to one of the opening / closing member constituting body and the other of the opening / closing member constituting body And a magnetic detection means for detecting a change in magnetic force of the permanent magnet accompanying relative movement of the opening / closing member constituting body, wherein the magnetic detection means comprises a plurality of reed switches for detecting the magnetic force of the permanent magnet. These reed switches are characterized in that their respective switching operation directions are arranged so as to be substantially orthogonal within substantially the same plane.

  The open / close member state detection apparatus configured as described above selectively adjusts the reed switch having a different switching direction by adjusting the position of the magnetic detection unit with respect to the permanent magnet at a predetermined installation position. It can be opposed to a permanent magnet.

Here, since the switching direction of each reed switch is different, the sensitivity for detecting the magnetic force of the permanent magnet is also different.
Therefore, by monitoring the sensitivity of magnetic force detection in a plurality of reed switches that are opposed to selection by the permanent magnet, a reed switch with high magnetic detection efficiency can be selected, and the selected reed switch can be selected as the permanent magnet. The magnetic detection means can be installed in a state of being opposed to each other.

  Therefore, even when the installable position changes, stable magnetic detection can be performed by adjusting the direction of the magnetic detection means, so that versatility can be enhanced.

  The opening / closing member structure is a door installed in the opening, and a thumb turn attached to the door. The permanent magnet is attached to the thumb turn, and the magnetic detection is performed at a portion of the door adjacent to the thumb turn. It can be set as the structure to which the means was attached.

  With this configuration, it is possible to detect the locking position and the unlocking position by the thumb turn, and thereby detect the locking and unlocking of the door.

  When the opening / closing member constituting body is a pair of sliding doors, the permanent magnet is attached to one of the sliding doors, the magnetic detection means is attached to the other sliding door, and the sliding doors are closed. In addition, the magnetic force of the permanent magnet can be detected by at least one of the plurality of reed switches.

  With such a configuration, the open / closed state of the sliding door can be detected based on the presence or absence of magnetic detection by the magnetic detection means.

  Then, regardless of whether it is applied to the thumb turn described above or applied to the sliding door, a plurality of reed switches having different magnetic detection directions can be selected as permanent magnets by adjusting the posture of the magnetic detection means. Since it can be made to oppose, stable magnetic detection can be ensured.

  Further, the magnetic detection means includes a light emitter that displays ON / OFF of the reed switch, a control means that is connected to the reed switch and the light emitter and controls light emission of the light emitter, and the light emitter. And it can be set as the structure provided with the storage battery which supplies drive electric power to a control means.

  With such a configuration, the function of the magnetic detection means can be completed by the magnetic detection means alone.

  Further, the state of the opening / closing member can be easily and reliably visually recognized by notifying the state of the opening / closing member based on the presence / absence of light emission of the light emitter and the change in emission color.

On the other hand, a MEMS magnetic sensor can be used as the magnetic detection means.
Then, by adjusting the magnetic detection sensitivity of the MEMS magnetic sensor, it is possible to detect a magnetic force change accompanying a change in the position of the opening / closing member structure, so that the positional relationship between the opening / closing member structure and the magnetic detection means Regardless, the state of the opening / closing member structure can be detected.

  Furthermore, the said permanent magnet can be fixed to the fastening body provided with the adhesion function, and this fastening body can also be attached to the said opening-and-closing member structure.

  By setting it as such a structure, the application to the existing opening-closing member structure can be made easy.

According to the state detection device for an opening / closing member of the present invention, even when the installation position is limited, a plurality of reed switches having different switching directions with respect to the permanent magnet by adjusting the direction of the magnetic detection means Can be selectively opposed to effectively detect the magnetic force of the permanent magnet.
Further, by using a MEMS magnetic sensor as the magnetic detection means, the magnetic detection sensitivity of the MEMS magnetic sensor is adjusted to improve the accuracy of position detection of the permanent magnet, that is, the state detection of the opening / closing member structure. Can do.
Thereby, the range of applicable types of the opening / closing member constituting bodies and the installable positions can be expanded, and the versatility thereof can be enhanced.

FIG.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
In these drawings, reference numeral 1 denotes a state detection device according to the present embodiment, and this state detection device 1 is a door as an opening / closing member structure A that constitutes an opening / closing member that can be opened and closed in an opening of a building. 2, a thumb turn 3 attached to the door 2, and a magnetic detection means 4 attached to the surface of the door 2.

  The thumb turn 3 includes a flat operation portion 3a. A permanent magnet is incorporated in the operation portion 3a, and one side in the radial direction with respect to the rotation center is an S pole and the other side is an N pole.

The magnetic detection means 4 includes a substantially rectangular parallelepiped case C.
A storage recess D is formed in the case C. The storage recess D is divided into upper and lower parts by a partition wall 5, the lower part is a battery storage part D 1, and the upper part is a device storage part D 2.

  The battery storage unit D1 stores a dry battery or a chargeable / dischargeable secondary battery.

  The device storage portion D2 includes a plurality of reed switches 6 (6a, 6b, 6c) as magnetic sensors, a light emitter 7 that is caused to emit light by a detection signal from these reed switches 6, and the reed switch 6 On the basis of the detection signal, a control means 8 for controlling the light emission of the light emitter 7 and a switch 9 for starting them are provided.

  Each of the reed switches 6 (6a, 6b, 6c) is incorporated into the upper surface of the partition wall 5 at both ends in the length direction of the case C, and one reed switch 6a is connected to the case C. The other two reed switches 6b and 6c are incorporated along the width direction of the case C.

Thus, the switching direction of the reed switch 6a is installed so as to be substantially orthogonal to the switching directions of the other two reed switches 6b and 6c.
The other two reed switches 6b and 6c are installed on the substantially same line at a predetermined interval.

In the present embodiment, the light emitter 7 is configured by, for example, an LED, and can selectively emit light in red and blue.
When the magnetic detection is performed in the reed switch 6 (6a, 6b, 6c), the control means 8 emits blue light, and when the magnetic detection is not performed, red light is emitted. Yes.

  As shown in FIG. 2, the state detection device 1 of the present embodiment configured as described above is configured such that the magnetic detection means 4 is attached to the lower side of the thumb turn 3 attached to the door 2. Detects locking and unlocking.

  Here, in the door 2, a door handle 10 is mounted above the thumb turn 3, and a recess 2 a is formed in the door 2 inside the thumb turn 3, whereby the magnetic detection means. The area where 4 can be installed is limited below the thumb turn 3.

  Therefore, the magnetic detection means 4 must be installed with the case C facing up and down along the edge of the door 2.

  On the other hand, when the thumb turn 3 is in a horizontal state, the reed switch 6 must be installed in parallel with the magnetic field lines generated by the thumb turn 3 in order to detect the magnetic force.

  In order to install the magnetic detection means 4 under this condition, one of the reed switches 6b and 6c provided along the width direction of the case C is opposed to the thumb turn 3.

  In the magnetic detection, the distance between the magnetic detection means 4 and the thumb turn 3 must be taken into consideration.

  For this purpose, the switch 9 of the magnetic detection means 4 is operated to activate the control means 8 and the like, and the distance between the magnetic detection means 4 and the thumb turn 3 is reduced.

  When the distance reaches the magnetic detection range, the reed switch 6 performs magnetic detection, and based on the signal, the control means 8 performs the light emission processing of the light emitter 7.

  Accordingly, an appropriate distance of the magnetic detection means 4 with respect to the thumb turn 3 is set.

  For example, in the case where the light emitter 7 is a two-color light emitter as described above, the light emission process is performed by emitting red light in a state where no magnetic detection is performed, and when the magnetic detection is performed. It can also be made to emit blue light.

  If the thumb turn 3 is rotated after the magnetic detection means 4 is installed as described above, the magnetic force lines generated by the thumb turn 3 are also rotated, and the magnetic detection means 4 cannot perform magnetic detection. .

  The rotation position of the thumb turn 3 can be detected by the presence or absence of such magnetic detection. For example, when the magnetic detection is performed, the thumb turn 3 is in a locked state, and the magnetic detection is performed. If there is not, it can be assumed that the thumb turn 3 is in an unlocked state.

  Then, the light emission of the light emitter 7 is controlled in accordance with the presence or absence of the magnetic detection (blue light emission in the locked state and red light emission in the unlocked state) to notify the locked state of the door 2. Can do.

  Further, by adding a communication function to the magnetic detection means 4 and transmitting the above-described locked state to the portable information terminal, the locked state can be confirmed on the go.

On the other hand, when the installation position of the magnetic detection means 4 can be ensured only on the side of the thumb turn 3, the case C is positioned on the side of the thumb turn 3 as shown in FIG. At the same time, the reed switch 6 a disposed along the length direction of the case C is opposed to the thumb turn 3.
Thereby, the magnetic lines of force generated by the thumb turn 3 can be detected.

  FIG. 3 shows another embodiment of the present invention, in which the state detection device 1 is mounted on a pair of sliding doors 11 (11a and 11b).

  In this example, the installation position of the state detection device 1 is limited to a portion where the sliding doors 11 overlap when the sliding doors 11 are closed.

  That is, since the thickness of the frame 12 constituting the sliding door 11 is thin at the portion where the sliding doors 11 overlap, the installation position of the magnetic detection means 4 is limited to the end surface of the frame 12. The magnetic detection means 4 is attached by sticking the case C along the end face.

  Further, the permanent magnet 13 constituting the state detection device 1 is attached to another sliding door 11 so as to face the magnetic detection means 4.

  As described above, in the state detection device 1 of the present invention, even when the mounting positions of the constituent members are restricted, the direction of the magnetic detection means 4 is changed and a different reed switch 6 is selected. Thus, the permanent magnet can be opposed to the permanent magnet, whereby the magnetic force of the permanent magnet can be reliably detected.

  As a result, it is possible to provide an open / close member state detection device 1 that is extremely versatile.

Next, a second embodiment of the present invention will be described with reference to FIGS.
In this embodiment, the permanent magnet 14 is integrally attached to a fastening body 15 provided with an adhesive layer (not shown), and the fastening body 15 is attached to the operation portion 3a of the thumb turn 3 using the adhesive layer. The permanent magnet 14 is attached to the operation part 3a of the thumb turn 3 by being fastened to.

  By adopting such a configuration, it is not necessary to apply a magnetic force to the operation portion 3a itself, and it can be easily applied to the existing thumb turn 3.

Furthermore, a third embodiment of the present invention will be described with reference to FIG.
In this embodiment, instead of the reed switch 6 used in the first embodiment, a MEMS magnetic sensor 16 capable of adjusting the detection sensitivity of the magnetic strength of the permanent magnet 14 is used.

With this configuration, the MEMS magnetic sensor 16 can detect the direction of the magnetic field. For example, by adjusting the threshold value of the magnetic detection sensitivity, it is possible to detect the change in the position of the permanent magnet 14. The posture of the operation unit 3a of the thumb turn 3 can be detected.
Therefore, the freedom degree of the installation position of the said magnetic detection means 4 can be raised.

  The various shapes, dimensions, and the like of the constituent members shown in the embodiments are merely examples, and various changes can be made based on design requirements and the like.
