Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fitting in which an open / close detection switch is embedded so that it cannot be seen from the outside.

[0002]

[Prior Art]

 Doors, sliding doors, sliding doors, etc., used in general houses, and rotary doors, such as doors for doors and toilets, are often aesthetically demanded from the viewpoint of design. However, even if it has excellent fire prevention and shielding functions, there are few examples in which it is used as it is as a shielding material used in buildings. The same applies to the anti-theft function. No matter how excellent the theft detection equipment used in buildings, etc. is in terms of functionality, when it is installed and the aesthetic appearance is impaired, the Use is discouraged.

A magnetic sensitive type is a typical one of conventional door open / close detection switches. As shown in FIG. 4, a magnet portion 21 which does not require a drawer cord is attached to the inside of the movable side door 10, and a contact portion 22 which is paired with the magnet portion 21 is attached to the inside of the fixed side door frame 30. . A two-wire type cord 23 is pulled out from the contact portion 22, and one end of the cord 23 is controlled to be turned on / off by the contact portion 22. The other end of the cord 23 is connected to an alarm device such as a buzzer or an input terminal of the centralized monitoring device.

In this type of magnetically sensitive switch 20, when the magnet portion 21 approaches the contact portion 22 within a few mm when the door 10 is closed, the magnetic force acting on the contact portion 22 becomes strong, so that the contact portion 22 becomes stronger. 22 is turned on, and conversely, when the magnet portion 21 separates from the contact portion 22 as the door 10 is opened, the magnetic force acting on the contact portion 22 is weakened and the contact portion 22 is turned off. Therefore, the opening / closing of the door 10 can be detected from the on / off state of the contact portion 22. In this case, the on / off logic of the switch 20 may be reversed in consideration of the disconnection of the code 23 at the time of theft. Further, although the door 10 of this example is a rotary type supported by a hinge 11, a similar switch arrangement is adopted for a slide type.

[0005]

[Problems to be solved by the device]

 However, since the magnet portion 21 and the contact portion 22 of the door opening / closing detection switch 20 described above are attached to the outside of the door 10 and the door frame 30, the appearance is impaired for home use. In particular, when a plastic switch is attached to a wooden or wood-based fitting, the material and the color tone are different, which causes a feeling of strangeness. For this reason, the installation of door open / close detection switches is shunned for home use, and the measures such as theft prevention are currently behind the management system of buildings.

An object of the present invention is to improve such a point and to add an open / close detection function to a wooden or wood-based fitting without impairing its appearance. .

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a fitting for rotatably or slidably supporting a movable shield with a fixed support, wherein a magnet part and a contact part are assembled to a part of the shield. The magnet portion of the magnetic sensitive open / close detection switch is embedded, and the contact portion is embedded in a part of the support.

[0008]

[Action]

 In the fitting according to the present invention, the opening / closing detection switch of the shield is embedded inside the shield and the support so that they are not exposed to the outside. Don't worry about damaging. Moreover, since it has an open / close detection function, it is possible to construct an anti-theft alarm system similar to buildings. The application of this open / close detection switch is not limited to theft prevention. For example, a system that automatically turns on the light in the room when the door is opened, or a system unique to the home where the family member discovers that the sick person or the old person has opened the door of his room for help. It can also be used for systems.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1A and 1B are configuration diagrams showing a first embodiment of the present invention. FIG. 1A is a front view and FIG. 1B is a top view. This example shows a fitting in which a rotary door 10 is rotatably supported by a hinge 11 with respect to a door frame 30 as in FIG. In a normal household fitting, both the door 10 and the door frame 30 are made of wood or a wood-based material. Therefore, in the present invention, all the door open / close detection switches 20 are embedded inside the door 10 and the door frame 30. The place to be buried may be around the door 10, but if it is set near the upper part of the hinge 11 as shown in FIG. 1, since this is near the rotation axis of the door 10, the door 10 will be opened and closed for a long period of time. Also, there is little change in the positional relationship between the magnet portion 21 and the contact portion 22 (interval when closed and vertical position).

On the other hand, as the distance from the rotation axis of the door 10 increases, the detection sensitivity with respect to the rotation angle when the door 10 is opened increases. Therefore, the switch 20 may be embedded in the portion A or the portion B, for example. However, in this case, as the frequency of opening and closing the door 10 increases, the support of the hinge 11 loosens and the door 10 starts to move downward, so that the positional relationship between the magnet portion 21 and the contact portion 22 changes. It needs to be noted. That is, this type of magnetically sensitive open / close detection switch 20 often operates only when the distance between the magnet portion 21 and the contact portion 22 is increased to about 5 mm.

FIG. 2 shows a specific example of a method of embedding the switch 20. Since the wooden or wooden door 10 has the frame member 12 in the peripheral portion, the recess 13 for burying the magnet portion is formed therein. Then, when the magnet portion 21 is fixed to the concave portion 13 by screwing or the like, it is thin on the entire surface of the frame member 12 so as to cover the surface of the concave portion 13 (usually about 0.5 mm, about 3 mm for fire prevention). ) Affix a wooden or wood-based decorative material 14. As a matter of course, the material of the decorative material 14 is the same as the surface of the frame member 12 (the frame member itself or its surface decorative material). By doing so, no discomfort in appearance due to the attachment of the magnet portion 21 occurs.

The same applies to the door frame 30 side. That is, a recess 31 for embedding the contact portion is formed at a position facing the recess 13 of the door 10, and the contact portion 22 is fixed thereto. Then, a drawer cord recess 32 communicating with the recess 31 is formed so as to communicate with the outside of the door frame 30, and the drawer cord 23 is inserted therein and pulled out of the door frame 30. After this, the decorative material 33 is attached to the inner surface of the door frame 30 so as to cover the surface of the recess 31. By doing so, no discomfort in appearance due to the attachment of the contact portion 22 and the withdrawal cord 23 occurs.

FIG. 3 is a front view showing a second embodiment of the present invention. This embodiment exemplifies a fitting that slidably supports a sliding type sliding door (sliding door, sliding door, board door, etc.) 40 with a support having slide grooves 51, that is, a horizontal bar (kamoi, sill) 50. Usually, a plurality of sliding doors 40 of this type are used as a set, and therefore the open / close detection switches 20 are individually installed. In this example, the switch 20A is provided for the sliding door 40A, and the switch 20B is provided for the sliding door 40B.

In this case, the magnet part 21 (A and B are omitted) is embedded in the upper frame of the sliding door 40, and the contact part 22 is embedded in the upper part of the slide groove 51 of the crossbar 50. In this case, the lateral position of the contact portion 22 is set at a position facing the pair of magnet portions 22 at a predetermined closed position of each sliding door 40. Regarding the pullout cord 23, a recess is formed inside the rung 50 up to the middle to pass through it, but at the end, it is pulled out from an appropriate position onto the rung. The embedding method is the same as that described with reference to FIG. 2. Finally, the surface is covered with a decorative material so that it cannot be seen from the outside.

In any of the embodiments described above, when the door 10 or the sliding door 40 is opened by a predetermined angle or a predetermined distance from the closed position, the switch 20 is operated to notify the opening of the door 10. The vessel etc. can perform a predetermined operation. For this reason, it becomes possible to apply functions such as theft prevention to household fittings, and the appearance peculiar to fittings is not impaired. Moreover, the cost of burying the switch at the time of manufacturing a door etc. has an advantage that it is much lower than the cost of mounting this type of switch later.

[0016]

[Effect of the device]

 As described above, according to the present invention, it is possible to add an open / close detection function to a wooden or wood-based fitting which does not attach a foreign member without impairing its appearance. As a result, it becomes possible to build a control or monitoring system with high added value such as theft prevention and electric light control in the home. The present invention can be applied to aluminum-based or resin-based fittings as long as the material does not hinder the use of the magnetic sensitive switch.
