Description

  The present invention relates to an open / close detection device in which, for example, a main body is attached to one of a set of two windows and a detected body is attached to the other, and the main body detects the movement of the detected body when the window is opened and closed. .

  Conventionally, a magnetic proximity switch capable of monitoring the opening and closing of a door has been proposed as a device for detecting the opening and closing of a window or a door (see Patent Document 1). This magnetic proximity switch is configured so that a switch body is attached to a door frame, a magnet body is attached to a door, and one surface of the magnet body and one surface of the switch body face each other when the door is closed. When the door is closed, the magnetic flux of the magnet body close to the door passes through the reed switch provided in the switch body, and the contact of the reed switch is closed. When the door is opened, the magnet body is separated, so that the magnetic flux does not pass through the reed switch and the reed switch contact is opened. In this way, the magnetic proximity switch can detect the opening and closing of the door.

  In addition, a wireless crime prevention system that detects opening and closing of windows has been proposed (see Patent Document 2). In this wireless security system, a wireless transmitter is attached to the side edge of one window frame body of two windows, and the side edge of the other window frame body or the window glass is permanently attached to this wireless transmitter. A magnet is attached. Thereby, the wireless crime prevention system can detect opening and closing of the window by the magnetic flux as in the magnetic proximity switch described above.

  Here, since the magnetic proximity switch and the wireless security system detect opening / closing of the window by the magnetic flux of the magnet, it is necessary to accurately position the positional relationship with the magnet at the time of installation.

  Regarding the positioning of the mounting position, a transmitter that can easily set and check the mounting position has been proposed (see Patent Document 3). This transmitter does not transmit an unnecessary warning signal in the construction mode by switching between the construction mode and the warning mode. Thereby, it is supposed that it can confirm at the time of construction whether an attachment position is appropriate.

  However, the transmitter is designed to check whether the installation position is appropriate by checking the operation by opening and closing the window after installation. It was time-consuming to re-install and check the operation.

Japanese Patent Laid-Open No. 10-12109 Japanese Patent No. 2775611 JP 2004-353205 A

  In view of the above-described problems, an object of the present invention is to provide an open / close detection device that can easily make an appropriate positional relationship with an object to be detected at the time of installation, and to improve the convenience of installation.

A mounting surface to be mounted, and the fixing means is disposed on both the inner side of the mounting surface side and the opposite surface side of the housing case; and the case side engagement provided on the main body. An urging portion configured to be symmetric with respect to both ends of the mounting surface when viewed from the front, and urged toward the case side engagement portion toward the main body side. More strongly from the opposite surface toward the mounting surface The Configure case side engagement portion so as to energize, on a rear surface of the accommodating case, characterized in that said a closing detection device provided with a position confirmation means for confirming the positional relationship between the detection object.

The first structure and the second structure may be configured by relatively opening and closing structures such as windows and windows, windows and window frames, doors and door frames, drawers and drawer storage frames.
The housing case can be formed in various shapes such as a front view rectangle, a front view square, and a front view hexagon.

With the above configuration, the position can be confirmed by the position confirmation means, and the positional relationship between the detected object and the open / close detection device can be appropriately installed. Therefore, it is not necessary to perform the troublesome work of checking the operation by attaching it for the time being, and starting again if it is inappropriate, and can be easily installed.
Further, the center of gravity of the entire open / close detection device can be brought closer to the mounting surface side.

As an aspect of the present invention, the position confirmation means can be configured by a hole formed in the back surface of the housing case.
Thus, for example, the detection object is temporarily attached or permanently attached, and the accommodation case is attached in a state where the detection object is visible from the hole, or the accommodation case is temporarily attached or permanently attached, and the hole part The detected object can be attached to a position facing the hole while checking the detected object. Therefore, the positional relationship between the detected object and the hole can be easily made appropriate.
Further, if the position of the detection means provided in the main body is made to correspond to the hole in this aspect, the storage case does not block between the detected object and the detection means, so that the detection accuracy by the detection means is improved. Can do.

  Further, as an aspect of the present invention, a fitting convex portion that protrudes toward the rear surface and fits into the hole portion is provided on the back side of the main body, and the detection means can be disposed at an inner position of the fitting convex portion. .

  Thereby, the positional relationship between the detection means and the detection target can be easily made appropriate. In addition, it is possible to prevent the distance between the detection means and the detected body from being increased by the thickness of the member constituting the back portion of the storage case, and when the detection means and the detected body are closest to each other The distance between the two can be shortened.

Further, as an aspect of the present invention, one side surface of the housing case may be an attachment surface that is attached to the structure, and the position confirmation unit may be provided symmetrically in both end directions of the attachment surface when viewed from the front.
As a result, the open / close detection device can be attached in accordance with various open / close directions and arrangements, and the positional relationship can be easily made appropriate regardless of the attachment.
For example, if the opening / closing detection device is attached to a sash of a pair of doors that opens to the left and right, when the attachment surface is on the left side, a storage case can be attached to the sash from the right side, and the main body can be stored from the front. Conversely, when the attachment surface is on the right side, the housing case can be attached to the sash from the left side, and the main body can be housed from the front. At this time, since the fixing means is symmetrical in both directions of the mounting surface (that is, symmetrical in the vertical direction in this example), even if the storage case is mounted upside down, the main body is stored in the storage case with the vertical direction as it is. can do.

As an aspect of the present invention, the detection means can be constituted by a reed switch.
Thereby, an opening / closing detection apparatus can be manufactured at low cost.

  According to the present invention, it is possible to provide an open / close detection device capable of easily making an appropriate positional relationship with a detected object at the time of installation, and to improve the convenience of installation.

  As shown in FIG. 6, the urging unit 62 and the urging unit 72 are disposed to face each other in the left-right direction. Here, FIG. 6A shows a cross-sectional view taken along the line AA in FIG. 5, and FIG. 6B shows a cross-sectional view taken along the line BB in FIG.

  As shown in FIG. 4, the urging portion 72 includes an elastic plate 73 provided at the front side end of the extraction window 75 portion provided on the right side surface 71 so as to hang down from the front surface to the back surface, and the elastic plate 73. As shown in FIG. 6, the back surface side end of the projection portion 74 is formed with a convex portion 74 that is projected inward. The elastic plate 73 is formed so as to be slightly inclined inward toward the end where the convex portion 74 is provided. For this reason, the urging | biasing part 72 can urge | bias the main body 10 accommodated firmly. The urging portion 72 is integrally formed with the housing case 40 made of resin.

  Like the urging portion 72, the urging portion 62 includes an elastic plate 63 provided on the extraction window 65 and a convex portion 64, and the position of the convex portion 64 in the front and back direction is the same as that of the convex portion 74. However, the protruding height H <b> 1 in the width direction of the convex portion 64 is formed to be lower than the protruding height H <b> 2 of the convex portion 74. The elastic plate 63 has the same thickness and size as the elastic plate 73, and the elastic force generated by the elastic plate 63 is the same as the elastic force generated by the elastic plate 73. Yes.

  Due to the difference between the protrusion height H1 and the protrusion height H2, the main body 10 is more strongly biased toward the adhesive attachment portion 57 attached to the sash 3b. As a result, the center of gravity of the entire open / close detection device 8 can be brought closer to the adhesive attachment portion 57 side regardless of whether the main body 10 is stored in the upper or lower direction with respect to the storage case 40.

  Thus, the convex portions 64 and 74 function as a case side engaging portion, and the concave portion 18 functions as a main body side engaging portion, and the main body 10 is accommodated by the case side engaging portion and the main body side engaging portion. A fixing means for fixing to 40 is configured.

  On the upper surface 51 of the housing case 40, a groove 52 and a hole 53 are provided in a straight line in the front and back direction at the center position in the width direction. A groove 52 and a hole 53 are also provided on the lower surface 54 of the housing case 40. The groove 52 and the hole 53 are provided symmetrically on the upper surface 51 and the lower surface 54. The light guide 35 of the main body 10 is positioned in the groove 52 and the push button 39 of the main body 10 is positioned in the hole 53 in a state where the main body 10 is stored in the storage case 40.

  With the above configuration, it is possible to provide the open / close detection device 8 that can be attached to an appropriate position corresponding to various open / close directions and arrangements.

  Specifically, as shown in FIG. 1, when the adhesive is fixed to the left side surface of the sash 3b, the left back window 2 and the right front window 3 are closed as shown in the perspective view of FIG. Then, the adhesive attachment portion 57 (see FIG. 2) of the housing case 40 is lightly applied to the left side surface of the sash 3b.

  Then, as shown in FIG. 5, the permanent magnet 7 is positioned so that the permanent magnet 7 can be seen in the position confirmation hole 83 when viewed from the front, and the permanent magnet 7 is attached and fixed to the glass 2a. Thereby, the permanent magnet 7 can be easily affixed and fixed to an appropriate position.

  Next, a double-sided tape is affixed to the adhesive attachment portion 57, and the housing case 40 is affixed and fixed to the left side surface of the sash 3b. At this time, the position confirmation hole 83 and the permanent magnet 7 face in the front-rear direction by positioning so that the permanent magnet 7 can be seen in the position confirmation hole 83 when viewed from the front, and attaching and fixing the housing case 40. It is possible to face the front face without any deviation in the vertical and horizontal positions. This positioning can also be easily performed visually.

  Further, as indicated by an arrow in FIG. 2, the main body 10 is inserted into the housing case 40 so that the convex portion 64 and the convex portion 74 are fitted into the concave portion 18, as shown in the vertical right side view of FIG. 8. The main body 10 is fixed to the housing case 40.

  When fixed, the reed switch accommodating convex portion 26 of the main body 10 is positioned in the position confirmation hole 83, and the reed switch 31 is positioned therein. For this reason, the position of the reed switch 31 is the position facing the permanent magnet 7. At this time, the outer surface of the reed switch housing convex portion 26 and the outer surface of the back surface 81 of the housing case 40 are located on substantially the same plane and are flush with each other. With this flush configuration, even when the back surface 81 of the storage case 40 is brought close to the permanent magnet 7, the reed switch housing convex portion 26 protrudes from the back surface 81 to the back side when the main body 10 is stored, and the permanent magnet 7. Can be prevented from touching.

  Further, since the reed switch housing convex portion 26 protrudes from the position confirmation hole 83 to the back side (permanent magnet 7 side), the thickness of the back surface 81 of the housing case 40 is between the reed switch 31 and the permanent magnet 7. Therefore, the reed switch 31 and the permanent magnet 7 can be brought close to each other.

  In the example shown in the drawing, a certain interval is provided between the reed switch accommodating convex portion 26 and the permanent magnet 7, but they may be further brought close to each other so as not to contact each other. The closer the distance is, the higher the reliability of opening / closing detection.

  If the opening / closing detection device 8 is attached to the sash 3b and the left back window 2 or the right front window 3 is opened as shown in the perspective view of FIG. 9, the permanent switch that is close to the reed switch 31 of the opening / closing detection device 8 is used. The magnet 7 is separated, and opening / closing can be detected.

Furthermore, when the left side is the front and the right side is the back, the housing case 40 is turned upside down as shown in the perspective view of FIG. 10, and the left side surface is turned upside down on the right side surface of the sash. It is possible to fix the adhesive mounting portion 57 located at the position with a double-sided tape.
Also in this case, the permanent magnet 7 and the open / close detection device 8 can be attached and fixed to the windows 2 and 3 by making the positional relationship between the permanent magnet 7 and the reed switch 31 easily suitable by the mounting method described above.

  In this way, regardless of the arrangement of the window or door to be attached, the orientation of the accommodation case 40 is appropriately set and bonded and fixed, and the main body 10 is provided with the open / close detection device 8 that can be accommodated in the accommodation case 40 in the same orientation. Can be provided. The reed switch accommodating convex portion 26 can be positioned in the position confirmation hole 83 without changing the orientation of the main body 10 even if the orientation in which the accommodating case 40 is bonded and fixed to the window or door changes.
