  However, when releasing the locked state of the shade and the main body, the shade is rotated in the circumferential direction contrary to the case where the shade is fixed. When this shade is rotated, one end edge of the insertion hole presses the side portion of the operation plate hanging downward from the insertion hole from the insertion hole in the rotation direction, and there is a concern that the operation plate may be caught in the insertion hole. The If the operation plate is caught in the insertion hole in this way, not only the operation plate is damaged, but also the stress propagates to the microswitch and the microswitch may be damaged.

  The present invention was made in order to solve the problem in releasing the fixed state of the cover and the main body in the conventional emergency lighting apparatus as described above, and its purpose is to perform inspection in releasing the fixed state of the cover and the main body. It is an object of the present invention to provide an emergency lighting apparatus that can be appropriately released without damaging a switch or the like.

  An emergency lighting apparatus according to the present invention includes: a storage battery; a charging circuit for receiving the supply of commercial power and charging the storage battery; a light source that is turned on when power is supplied from the storage battery; A lighting circuit for supplying electric power from the storage battery to the light source; a switch for causing the lighting circuit to perform control for supplying electric power from the storage battery to the light source instead of charging the storage battery when the commercial power source is not shut off; A case containing a charging circuit, a lighting circuit, and a switch; a main body in which the case and the storage battery are disposed; an operation piece configured to protrude from the case in the direction of gravity due to its own weight; It is attached by turning in one direction so as to cover the main body from the operation piece side of the case, and it is unlocked by turning in the direction opposite to the above direction, corresponding to the position of the operation piece A cover in which a hole is formed; the operation piece protrudes from the case by its own weight, and the movable range in one direction that moves when the operation piece is released from the home position is fixed from the home position. And a hole formed in the case so that a position larger than the movable range in the opposite direction to the home position becomes a home position.

  The main body is attached in a state of protruding from an attachment surface such as a ceiling, or attached in a state of not protruding. The operation piece is called a knob or a lever and is operated by hand. The operation of the lighting circuit for supplying power from the storage battery to the light source when the commercial power source is not shut off according to the operation of the operation piece enables inspection when necessary. Besides the operation of the operation piece, the lighting circuit is allowed to supply power from the storage battery to the light source by an instruction by wired communication or by an instruction by wireless communication from a remote controller. The home position means a position where the operation piece protrudes from the case by its own weight when the main body is attached to a mounting surface such as a ceiling. The light source accepts a halogen light bulb, an LED, or the like.

  In the emergency lighting apparatus according to the present invention, in the case of rotation to release the fixed state of the cover and the main body, before the end of the hole in the cover exceeds the movable range of the operation piece, A stopper for stopping the rotation is provided.

Charging.

  In the emergency lighting apparatus according to the present invention, the operation piece protrudes from the hole formed in the case by its own weight, and in this hole, the operation piece moves in one direction when moving from the home position when the operation piece protrudes. Since the home position is the position where the range is larger than the movable range in the direction opposite to the direction of fixing from the home position, it is formed on the cover when the cover is rotated in the direction of unlocking. The formed hole moves to abut against the operation piece and moves the operation piece. However, since this movable range is large, the operation piece rotates around the rotation axis and retracts to the inside of the case. Thus, it is possible to avoid the problem that the operation piece is caught in the hole formed in the cover. For this reason, it is possible to appropriately release the cover without damaging the operation piece or the switch.

  The emergency lighting apparatus according to the present invention, in the case of rotation to release the fixed state of the cover and the main body, before the end of the hole in the cover exceeds the movable range of the operation piece, presses the operation piece, Since the stopper for stopping the rotation is provided, the operation piece and the switch can be appropriately prevented from being damaged without being pushed beyond the movable range of the operation piece.

  In the emergency lighting apparatus according to the present invention, when the lighting circuit detects that the switch is turned on and off in a predetermined sequence by operating the operation piece, the light source is turned on for a predetermined time specified in the inspection mode, and the rechargeable battery thereafter. Therefore, it is convenient that the light source is turned on for a predetermined time and the rechargeable battery is subsequently charged without continuing to operate the operation piece.

  Hereinafter, embodiments of an emergency lighting apparatus according to the present invention will be described with reference to the accompanying drawings. In each figure, the same components are denoted by the same reference numerals, and redundant description is omitted. As shown in FIG. 1, the emergency lighting apparatus according to the embodiment is provided with a storage battery box 20 and a unit case 30 in a main body 10 which is a bottomed cylindrical container.

Connected to an AC power source (AC 100 V) via an AC connector 11 provided on the main body 10, a charging circuit 31 that charges the storage battery 21 in the storage battery box 20, a lamp 44 is turned on based on the power of the storage battery 21, and an inspection or the like Are provided with a lighting circuit 33 for controlling in various cases, a remote control module 35 for the lighting circuit 33 to communicate with the remote control, and a wired communication connector 34 for the lighting circuit 33 to communicate with the main operation panel or the like through a wired line. ing.

  The lighting circuit 33 is connected to a micro switch 46 and a charge monitor LED 47 and a lamp monitor LED 48. As shown in FIG. 4, the micro switch 46 is turned on and off by operation of a knob 49 that is an operation piece protruding in the direction of gravity from the hole 45 of the unit case 30.

  The configuration relating to the micro switch 46 and the knob 49 is shown in FIGS. The micro switch 46 is mounted on a printed circuit board 51 on which the charging circuit 31 and the like are mounted. A button portion 52 is provided on the surface side, and a spring 53 is provided on the button portion 52. The spring 53 hangs downward in a slope shape from the upper portion of the button portion 52, and is configured to be separated from the housing of the microswitch 46 as it goes downward, and is suspended in a U-shape at the foremost portion. A lower portion 54 is provided.

  The knob 49 is suspended from the suspended portion 54 through a hole 49 a formed in the upper portion of the knob 49, and the tip of the knob 49 is inserted into the hole 45 of the unit case 30. The hole 49a formed in the upper part of the knob 49 is formed long in the vertical direction, and the suspension part 54 is inserted into the long hole 49a, so that the tip side (lower end part) of the knob 49 is on the upper side (such as the ceiling). The knob 49 enters the unit case 30 by being pushed in the direction), and the knob 49 is suspended from the hole 45 of the unit case 30 by its own weight when the distal end side (lower end) of the knob 49 is freed. By pulling the knob 49 in a state where the knob 49 is suspended, the spring 53 extends linearly, and a part of the spring 53 touches the button portion 52 to turn on the micro switch 46. Further, by releasing the knob 49 from the pulled state, the shape of the spring 53 is restored and a part of the spring is separated from the button part 52, and the micro switch 46 is turned off. A frame 45a is provided around the inside of the unit case 30 in the hole 45 to prevent the knob 49 from coming off when the knob 49 moves in the vertical direction.

  A bottomed cylindrical cover 60 is covered from the opening side of the main body 10. As shown in FIG. 1, a hole 61 through which light emitted from the lamp 44 is emitted is formed at the center of the surface of the cover 60, and a charge monitor LED 47, a lamp monitor LED 48, a knob 49, and a remote controller are formed on the surface. Holes 64, 65, 66, and 67 are formed at positions corresponding to the modules 35, respectively.

  As shown in FIG. 6, engagement claws 63, 63 are provided on the inner wall portion of the cover 60 at opposing positions by diameter. As shown in FIG. 10 and FIG. 2, inverted L-shaped engagement grooves 12 and 12 are formed on the side of the main body 10 at positions corresponding to the engagement claws 63 and 63. 63 and 63 are reverse U-shapes, and are configured to slide while sandwiching the lower edge 12a of the engaging grooves 12 and 12 extending in the lateral direction. For this reason, when the cover 60 is put on the main body 10 to be coupled and fixed, as shown in FIG. 10, the marks M of the main body 10 and the marks M of the cover 60 are aligned and the engaging claws 63 and 63 are engaged. The cover 60 is pressed to the main body 10 side (ceiling side) so as to be aligned with the starting end of the grooves 12, 12, the cover 60 is in contact with the opening edge of the main body, and the cover 60 is on the main body 10 side (ceiling side). When the cover 60 can no longer be moved, the cover 60 is rotated in the fixing direction (the direction of arrow A in FIGS. 1 and 10).

  When the cover 60 is put on the main body 10 and pressed to the main body 10 side (ceiling side) in the mounting operation of the cover 60 described above, the knob 49 is located near the hole 66 of the corresponding unit case 30. The unit case 30 is pressed into the unit case 30 through the hole 45 in the unit case 30. When the cover 60 is rotated in the fixing direction (the direction of arrow A in FIGS. 1 and 10), the positions of the hole 45 of the unit case 30 and the hole 66 of the cover 60 are overlapped, and the knob 49 protrudes from these holes. According to the rotation, the knob 49 protrudes from the hole 66 of the cover 60 to the outside by its own weight. When the cover 60 is further rotated in the fixing direction (the direction of the arrow A in FIGS. 1 and 10), the engaging claws 63 and 63 come into contact with the end of the engaging grooves 12 and 12 and cannot be rotated. At this time, the hole 45 of the unit case 30 and the hole 66 of the cover 60 are positioned corresponding to each other, and the state shown in FIG. 7 is exhibited.

  When the attachment is completed, the knob 49 is in the home position in the hole 45 of the unit case 30. Here, as shown in FIG. 5, the movable range Lb from the home position HP when the knob 49 protrudes to the direction of movement when the lock is released (in the direction of arrow B) is the above-mentioned direction when the knob 49 is fixed from the home position HP. A position that is larger than the movable range La in the direction opposite to the (arrow B direction) (arrow A direction) is set to the home position HP. That is, the knob 49 is not located in the center position in the hole 45 of the unit case 30 but is located unevenly on the fixed release side (right side in FIG. 5).

  In order to release the cover 60, the cover 60 is rotated in the direction of arrow B in FIGS. At this time, the hole 66 formed in the cover 60 moves and contacts the knob 49 to move the knob 49. Since this movable range is large, the knob 49 moves as shown in FIG. Accordingly, the vicinity of the suspension portion 54 that is a rotation shaft rotates around the rotation center and retracts to the inside of the unit case 30, so that the trouble that the knob 49 is caught in the hole 66 of the cover 60 can be avoided.

  Further, when the cover 60 is rotated in the direction of arrow B, which is the fixing release direction, the engaging claws 63 and 63 abut against the side edge 12b near the corners of the engaging grooves 12 and 12, and the rotation is stopped. This stop position is a position before the end of the hole 66 in the cover 60 presses the knob 49 beyond the movable range Lb of the knob 49, and the side edge 12b in the vicinity of the corners of the engaging grooves 12, 12. Constitutes a stopper.

  In the emergency lighting fixture configured as described above, the unit case 30 and the storage battery box 20 are housed and fixed in the main body 10, the reflector 41 is attached to the unit case 30, and the lamp 44 is fitted in the lamp socket 43. . The cover 60 is put on and fixed to the main body 10 as described above to complete the emergency lighting fixture as shown in FIG.

  When the unit case 30 and the storage battery box 20 are housed and fixed in the main body 10, the charging circuit 31 receives AC 100 V via the connector 11 to create a DC voltage, and starts charging the storage battery 21. Further, the lighting circuit 33 detects the disconnection of the commercial power source that arrives at the connector 11, and when the commercial power source is disconnected, executes the control for supplying the power of the storage battery 21 to light the lamp 44.

  Further, as shown in the flowchart shown in FIG. 8, the lighting circuit 33 detects the charged state based on the potential of the storage battery 21 (S11), and continues the state (full charge, uncharged, etc.) in the charge monitor LED 47. Displayed by lighting or flashing (S12). Further, normality or a lamp-out state of the lamp 44 is detected by passing a current through the lamp 44 (S13), and the state (normal or lamp-out state) is displayed on the lamp monitor LED 48 by continuous lighting or blinking (S14). ).

  The lighting circuit 33 performs processing shown in the flowchart shown in FIG. 9 in addition to the above operation. That is, the presence / absence of an instruction from the remote control via the remote control module 35 is detected (S21), the presence / absence of an instruction from the main operation panel via the wired communication connector 34 is detected (S22), and the micro switch 46 is turned on. (S23). If YES in steps S21 and S22, it is detected whether the instruction is a periodic inspection instruction or a monitor instruction of the state of the storage battery 21 or the lamp 44 (S24).

  When it is detected in step S24 that it is an instruction for periodic inspection, the power of the storage battery 21 is supplied and the lamp 44 is turned on for a predetermined time, and then the lighting is stopped and charging of the storage battery 21 is started. The necessary state (lighting state of the lamp 44 and charging state of the storage battery 21) information is transmitted via the remote control module 35 or the wired communication connector 34 (S25).

  If it is detected in step S24 that the instruction is to monitor the state of the storage battery 21 or the lamp 44, the state information detected by the flowchart of FIG. 8 is transmitted via the remote control module 35 or the wired communication connector 34 (S26). On the other hand, as shown in FIG. 3, the main operation panel and the remote control include a control unit 70, an operation unit 71 such as a key, a display unit 72 such as an LCD, and a communication unit (for those corresponding to the main operation panel). In the case of a wire communication unit and a remote control compatible unit, a wireless communication unit) 73 is connected. The control unit 70 receives the above information via the communication unit 73, displays the information on the display unit 72, and can conveniently know the state of the storage battery 21 and the state of the lamp 44 remotely.

  On the other hand, when it is detected in step S23 that the micro switch 46 is turned on, the power of the storage battery 21 is supplied to turn on the lamp 44 (S27). Subsequent to this step S27, it is detected whether the micro switch 46 is turned off (S28), the lighting of the lamp 44 is stopped, and charging of the storage battery 21 is started (S29). Next, it is detected whether the microswitch 46 is turned on or off in a predetermined pattern (S30). Here, the predetermined pattern is, for example, a case where ON / OFF is repeated a predetermined time (for example, 5 times) within a predetermined time (for example, 5 seconds).

  If on / off of the predetermined pattern as described above cannot be detected in step S30, the process returns to step S21. As a result of the processes in steps S27, S28, and S29, the lamp 44 is turned on only when the knob 49 is pulled, so that the inspector can perform a desired manual check. On the other hand, in step S30, when the on / off state of the predetermined pattern as described above is detected in step S28, the power of the storage battery 21 is supplied and the lamp 44 is turned on for a predetermined time (S31) and then turned on. The control is resumed to stop and charge the storage battery 21 (S32). Thus, the micro switch 46 is turned on and off in a predetermined pattern by a predetermined operation of the knob 49 by an inspector, and it is convenient that a periodic inspection of continuous lighting for a predetermined time can be realized.
