Abstract

PURPOSE: To surely confirm locking of a handle, so as to improve the security by providing such an arrangement that a magnet or the like attached to the handle is located in proximity with a sensor provided to a stationary frame, when the handle is locked. CONSTITUTION: A locking handle 20, made of nonmagnetic materials and incorporating a magnet (or a magnetic material) 26 in its locking part at the front end thereof, is attached to a fixture 22 in a vertical frame 16 so as to be turnable about a shaft 23. A sensor 27 such as a proximity switch or a reed switch is attached to an auxiliary frame 13, which is attached thereto with a handle receiver 24 made of nonmagnetic materials. With this arrangement, when the handle 20 is turned so as to allow a locking part 20a to abut against the handle receiver 24 in order to lock the locking part 20 to the latter, the magnet 26 is made to approach the sensor 27 which therefore becomes operable. With this arrangement, the sensor 27 will not operate unless locking is made by the handle 20, even though a window body 14 is closed. That is, since the sensor 27 operates only when locking is made by the handle 20, it is possible to confirm locking.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for checking whether a door is closed in a window or door such as a vertical opening window, a horizontal opening window, or a casement window.

(Prior Art) Home security systems that centrally monitor door locks, etc. are becoming popular in recent homes for crime prevention. The conventional door lock confirmation device has a fixed frame l as shown in Fig. 5.
For example, a sensor 4 such as a reed switch is attached to the upper frame 2 (3 is a vertical frame), and the upper frame 6 (8) of the window or door body 5 is attached.
is a stile. ), and the sensor 4 is connected to a central monitoring controller (not shown) via a wire 9, and if the window or door body 5 is closed, the sensor 4 is activated, and the sensor 4 is connected to the Display is performed using a display element.

(Problem to be solved by the invention) However, according to this conventional device, even if you forget to lock the door, if the window or door is closed, the sensor 4 will be activated, and it will be possible to confirm that you have forgotten to lock the door. There was a problem that it wasn't there.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a door 1 tightness confirmation device that is attached to a handle receiving portion of a fixed frame of a window or door, and that is installed in the vicinity of a magnet or a magnetic material. It consists of an activated sensor and a magnet or magnetic body attached to a locking handle attached to the window or door body, and has a structure in which the sensor is activated by the magnet or magnetic body being close to the sensor when the handle is locked. It is something.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3, taking a casement window as an example. FIG. 1 is a cross-sectional view of a casement window, and lO is a fixed frame fixed to the opening of a building, which is made up of a vertical frame 11 and a horizontal frame 12 made of aluminum or resin profiles, etc., combined in a rectangular shape. . In the fixed frame IO of this embodiment, an auxiliary frame 13 made of the same profile material as described above for attaching the window main body 14 is attached to the opposite surface of the vertical frame 11.

The window body 14 is made up of vertical frames 15, 16 and a horizontal frame 17 made of the same material as the fixed frame 10, assembled in a rectangular shape, and a panel 18 is attached inside. The window body 14 is attached so that it can be opened and closed freely, and a locking handle 20 made of a non-magnetic material such as zinc die-casting is attached to the other vertical stile 16, and a metal fitting 22 is attached to the vertical stile 16 with a fixing device 21 such as a screw. It is rotatably mounted around a shaft 23. Reference numeral 24 denotes a handle holder made of a non-magnetic material such as zinc die-casting, which is attached to the auxiliary frame 13 with a fixing device 25 such as a screw (see Figs. 2 and 3). Hashi 1~ru 20
Rotate the locking part 20a at the tip of the handle holder 2.
The structure is such that it can be locked by making contact with 4.

Therefore, in the present invention, a magnet (or magnetic material) 26 is built in the locking part 20a at the tip of the handle 20, and a part 13a of the auxiliary frame 13 having a rectangular cross section to which the handle holder 24 is attached. A sensor 27 such as a leet switch or a proximity switch is built in. Then, as shown in FIG. 2, the locking portion 20a of the handle 20
In the unlocked state where the magnet 26 is not in contact with the sensor 27, the sensor 27 is not activated.On the other hand, as shown in FIG. In the locked state in which the magnet 20a is brought into contact with the handle holder 24 and locked, the magnet 26 approaches the sensor 27, so that the sensor 27 is activated. The sensor 27 is wired through a coat 28 housed in the auxiliary frame 13 without being exposed to the outside, and is connected to a controller (not shown).

With this configuration, the sensor 27 does not operate when the window body 14 is closed, and the sensor 27 operates only when the handle 20 is used to lock the door, so that it can be confirmed whether the window is locked or not.

Note that in this embodiment, the sensor 27 and the magnet 26
are built into the auxiliary frame 13 and the handle 2o, respectively.
Unlike conventional models, no component parts are exposed, making it visually appealing.

Note that in order to incorporate the magnet 26 and the sensor 27 into the handle 20 and the auxiliary frame 13, the handle 20 and the auxiliary frame 13 must be
does not necessarily have to have a hollow cross-sectional shape, but may have a structure in which the magnet 26 and sensor 27 cannot be seen from the indoor side. For example, as shown in FIG.
0b may be formed into a U-shape in cross-section, and the magnet 26 may be attached by fitting or by attaching the magnet 26, and the handle receiver 24 of the auxiliary frame 13 may be attached by forming the portion 13b into an L-shape or a U-shape, etc. The sensor 27 may be attached to the portion 13b by bonding, adhesive bonding, or the like. Further, the present invention can be applied to a horizontal sliding window, a set-up window or a door, and in the case of a horizontal sliding window, the handle 2o having the magnet 26 is attached to the horizontal stile 17 of the window body 14, sensor 27
will be attached to the horizontal frame 12 of the fixed frame IO.

In addition, when implementing the present invention, windows or doors, fixed frames,
Various modifications and additions may be made to the specific structure, shape, etc. of the handle, its receiving portion, sensor, magnet, etc.

(Effects of the Invention) As described above, in the present invention, the sensor is activated when a magnet or the like is placed close to the sensor when the handle is locked. Since the sensor will not operate unless the door is locked, it can be confirmed whether the handle is locked or not, improving crime prevention.
