Description

  The present invention relates to a hook rosette for installing a lighting fixture on a ceiling and supplying power to the installed lighting fixture.

  Due to the recent improvement in performance of fire alarms, it is possible to cover the entire room with a single fire alarm if it is a room of about 10 tatami mats. It is desirable to install a fire alarm at the highest position in the center of the room. And the optimal installation place which satisfy | fills this condition is the ceiling center of a room. However, a hooking closet for hanging the main lighting is often installed in the center of the ceiling of the room, and a fire alarm cannot often be installed in the center of the ceiling. In such a case, in order to avoid interference with the hooked rosette, the fire alarm cannot be installed at a desired position, other than by shifting the installation position of the fire alarm.

  In addition, it is extremely rare that a power source other than the power source for lighting is provided on the ceiling, and even if the space for installing the fire alarm can be secured, the power source for the fire alarm cannot be secured. In many cases, you have to give up. Such a problem is a common problem that occurs not only when the fire alarm is installed in the center of the ceiling, but also when it is installed at any position on the ceiling.

Therefore, Patent Document 1 proposes a home security device that is interposed between an outlet with a locking groove fixed to the ceiling and an outlet with a locking piece shape provided in a hanging lighting fixture. Has been.
Japanese Patent Laying-Open No. 2001-250182 ([0011], FIG. 1)

  However, the home security device disclosed in Patent Document 1 is interposed between a locking grooved outlet (hanging rosette) and a lighting fixture, and the lighting fixture is not directly attached to the hooking rosette. Can not. That is, the technique disclosed in Patent Document 1 is intended to interrupt a fire alarm between an existing hook rosette and a lighting fixture. On the other hand, an object of the present invention is to provide a hook rosette in which a fire alarm means is built in in advance.

  The hook rosette of the present invention is a hook rosette capable of fixing a lighting fixture to the ceiling and capable of supplying power to the fixed lighting fixture. There is provided a fire notification section including a detection means for detecting both or one and a notification means for emitting both or one of sound and light based on a detection result of the detection means.

  The hook rosette of the present invention has a locking portion that can lock and release the locking claw provided on the fixture interposed between the lighting fixtures, and is locked to the locking portion. A power supply terminal electrically connected to the locking claw can be provided. Further, the fire notification unit can be provided with a communication unit capable of transmitting a signal to an external device based on a detection result of the detection unit. Further, a standby power source for the fire notification unit can be provided. Furthermore, it is possible to adopt a wiring structure in which electric power is always supplied to the fire alarm unit regardless of whether or not electric power is supplied to the lighting fixture.

  By simply fixing the luminaire to the ceiling using the hook rosette of the present invention, both the luminaire and the fire alarm can be installed at the same time, and it is not necessary to separately secure a power source for the fire alarm. Furthermore, it is not necessary to interrupt a separate fire alarm between the hook rosette and the lighting fixture.

  Hereinafter, an example of an embodiment of the hooking rosette of the present invention will be described with reference to the drawings. FIG. 1 is a bottom view of the hooking rosette 1 of this example. FIG. 2 is a cross-sectional view showing the internal structure of the hooking rosette 1 of this example. FIG. 3 is a side view showing the usage state of the hooking rosette 1 of this example.

  The configuration of the hooking rosette 1 of this example can be roughly divided into a main body case 2, a locking part 3, a terminal block 4 and a fire alarm part 5. As can be understood from FIGS. 1 and 3, the main body case 2 is formed of a synthetic resin and has a substantially disk-shaped appearance. Further, as shown in FIG. 2, a screw hole 10 for fixing the main body case 2 to the ceiling is formed on the upper surface of the main body case (a surface facing the ceiling when in use). The hook rosette 1 is fixed to the ceiling by screwing a screw (not shown) inserted into the screw hole 10 into the ceiling (see FIG. 3). In addition, a wiring hole 11 is formed in the center of the upper surface of the main body case for drawing a wiring (not shown) laid on the back of the ceiling and connected to a commercial power source through a switch or the like into the main body case 2. Yes.

  Further, a terminal block 4 is provided in the vicinity of the wiring hole 11, and the wiring drawn from the wiring hole 11 is connected to the terminal block 4. In addition, a pair of substantially arc-shaped locking portions 3 are provided in opposed states on both outer sides in the radial direction of the wiring hole 11. On the other hand, as shown in FIG. 1, an insertion hole 12 having substantially the same shape as the locking portion 3 is formed on the bottom surface of the main body case 2, and the locking portion 3 is connected to the main body case 2 via the insertion hole 12. It communicates with the outside. Then, the lighting fixture 30 can be hooked and hung on the rosette 1 by locking the locking claw (not shown) of the fixture 31 (FIG. 3) provided in the lighting device 30 to the locking portion 3. . Specifically, a pair of locking claws are projected from the mounting tool 31, and the locking claws are fitted into one end of the corresponding locking portion 3 through the insertion hole 12, and the engaged hook is engaged. When the pawls are rotated toward the other ends of the respective locking portions 3, the locking claws are locked to the locking portions 3. As a result, the luminaire 30 is fixed to the hooked rosette 1 via the fixture 31. However, since such a locking structure is standardized and is obvious to those skilled in the art, further description thereof is omitted. However, in order to fix the lighting fixture to the hooking rosette 1, the fixture interposed between the two may be separate from the lighting fixture. In particular, attachments that are compatible with ceiling-type lighting fixtures are often separate from the lighting fixtures. However, it will be apparent from the above description and the following description that the fixing structure and the connecting structure between the fixture and the lighting device are not essential matters of the present invention.

  Refer to FIG. 2 again. A power terminal (not shown) that is electrically connected to the terminal block 4 is provided on the inner surface of each locking portion 3, and the locking claw is locked to the locking portion 3 as described above. If it does, both will contact physically and a latching claw and a power supply terminal will conduct | electrically_connect. Furthermore, the latching claw is electrically connected to the power supply unit of the lighting fixture 30 via the cable 32 (FIG. 3). As described above, when the locking claw is locked to the locking portion 3, the lighting fixture 30 is hooked via the fixture 31 and suspended from the rosette 1, and power is supplied to the suspended lighting fixture 30. In FIG. 4, the wiring block diagram at the time of installing the lighting fixture 30 on a ceiling using the hook rosette 1 of this example is shown.

  Reference is again made to FIG. On the opposite side of the terminal block 4 across the wiring hole 11, a fire alarm unit 5 is provided. The fire notification unit 5 emits a sound when a detection means (not shown) (a temperature sensor in this example) that outputs a detection signal when heat of a predetermined temperature is detected and a detection signal output from the temperature sensor are input. And a notifying means (in this example, a buzzer 5a). These temperature sensor and buzzer 5a constitute a single unit. Furthermore, the fire alarm unit 5 is electrically connected to the terminal block 4, and power necessary for operating the temperature sensor and the buzzer 5 a is supplied via the terminal block 4.

  However, the detection means of the fire alarm unit 5 can be replaced with a smoke sensor that detects smoke and outputs a detection signal. Moreover, it can also be replaced with a thermal smoke sensor that detects both heat and smoke and outputs a detection signal. Moreover, it can also be set as the structure which alert | reports abnormality by light, making a notification means into a fluorescent lamp, a light bulb, LED, etc. Here, the thermal smoke sensor may be one in which the thermal sensor and the smoke sensor are integrated, or may be constituted by a separate thermal sensor and smoke sensor.

  In preparation for an emergency, the main body case 2 can be provided with a standby power source for the fire alarm unit 5. In addition, the fire notification unit 5 may be provided with a communication unit that transmits a signal to an arbitrary external device. For example, a communication unit including a signal generation unit that generates a predetermined signal based on the detection result of the detection unit and a signal transmission unit that transmits the signal generated by the signal generation unit in a wired or wireless manner can be provided. By providing such a communication means, a signal can be transmitted to a predetermined external device based on the detection result of the detection means, and the device can be notified of the abnormality. Further, the hooking rosette of the present invention in which the fire alarm unit having the communication means is provided in a plurality of rooms, and centralized management is performed by connecting the hooking rosette and the centralized management device by wire or wirelessly. It is also possible to do this. A specific system for realizing such centralized management can be easily realized by using or applying an existing management system used for centrally managing a plurality of fire alarms.

  Furthermore, as shown in FIG. 1, a slit 13 is formed on the bottom surface of the main body case 2 so that heat and smoke generated in the room can be detected early and reliably by the detection means. Further, a buzzer sound discharge hole 14 for discharging the sound generated by the buzzer 5 a (FIG. 2) to the outside of the main body case 2 is also formed on the bottom surface of the main body case 2. However, the slit 13 and the buzzer sound emitting hole 14 can also be formed on the upper surface or side surface of the main body case 2.

  In the wiring shown in FIG. 4, the lighting fixture 30 and the fire alarm unit 5 share the power source 40 and the terminal block 4. Therefore, when the power is turned off to turn off the lighting fixture 30, the power supply to the fire alarm unit 5 is cut off in conjunction with this. Therefore, the wiring can be changed so that power is always supplied to the fire alarm unit 5 regardless of whether the lighting fixture 30 is turned on or off. For example, as shown to Fig.5 (a), the 1st power supply 40a and 1st terminal block 4a for lighting fixtures, and the 2nd power supply 40b and 2nd terminal block 4b for fire alarm parts are provided separately. In this case, even if the first power supply 40a is turned on / off to turn on / off the lighting fixture 30, the fire notification unit 5 is always supplied with power from the second power supply 40b. Further, as shown in FIG. 5B, only the power source 40 is shared while leaving the first terminal block 4a and the second terminal block 4b of FIG. 5A, and the power source 40 and the first terminal block 4a By providing the switch 50 between them, it is possible to always supply power to the fire alarm unit 5 regardless of whether the lighting fixture 30 is turned on or off. Here, the switch 50 may be a wall surface switch interposed between the power source 40 and the first terminal block 4a, or provided inside the main body case 2 and turned on by operating the wall surface switch or other switches. It may be a relay to be turned off, a semiconductor switch, a mechanical switch, or the like. Of course, the wiring shown in FIGS. 5A and 5B is an example. In short, any wiring that supplies power to the fire alarm section regardless of whether or not power is supplied to the lighting apparatus may be used, and the wiring is not limited to a specific wiring. 5 (a) and 5 (b), the same reference numerals as those in FIGS. 1 to 4 indicate the same configuration.
