The third gasket 55 is made of an elastic material that transmits light, such as silicone rubber. The third gasket 55 has a main body 550, a first operation portion 551, a second operation portion 552, and a transmission portion 553, as shown in FIGS. 12A and 12B. The main body 550 is formed approximately in the shape of an elliptical cylinder. However, the lower surface of the main body 550 is formed into a curved surface having the same radius of curvature as the surface (lower surface) of the outer peripheral wall 510 of the first housing 51 . Three ribs 559 each having a triangular cross section parallel to the vertical direction protrude from the outer peripheral surface of the main body 550 so as to be arranged at regular intervals along the vertical direction. Furthermore, the body 550 has a first through hole 554 , a second through hole 555 and an indicator groove 556 . The first through hole 554 is formed in a cylindrical shape that vertically penetrates the main body 550 at one longitudinal end of the main body 550 . The second through hole 555 is formed in a cylindrical shape vertically penetrating the main body 550 at the other longitudinal end of the main body 550 . The display groove 556 is formed between the first through-hole 554 and the second through-hole 555 of the main body 550 and has a square tubular shape with an open lower surface. However, the lower portion of the display groove 556 in the vertical direction is connected to the first through hole 554 (see FIG. 12B). The transmissive portion 553 is composed of the bottom wall (upper wall) of the display groove 556 in the main body 550 (see FIGS. 12A and 12C).

The first operation portion 551 is formed in a cylindrical shape. The first operation portion 551 is accommodated in the first through hole 554 of the main body 550 so that the axial direction thereof is aligned in the vertical direction. The second operating portion 552 is formed in a cylindrical shape that is shorter than the first operating portion 551 . The second operation part 552 is accommodated in the second through hole 555 of the main body 550 so that the axial direction thereof is vertically aligned. Also, the third gasket 55 has a first seal portion 55 that seals the first through hole 554 .
7 and a second seal portion 558 that seals the second through hole 555 (see FIG. 12C). The first seal portion 557 and the second seal portion 558 are each formed in the shape of a hollow truncated cone with two open bottoms. The peripheral edge of the large-diameter bottom surface of the first seal portion 557 is coupled to the inner peripheral surface of the first through hole 554 of the main body 550 . The peripheral edge of the small-diameter bottom surface of the first seal portion 557 is coupled to the peripheral surface of the first operating portion 551 . The peripheral edge of the large-diameter bottom surface of the second seal portion 558 is coupled to the inner peripheral surface of the second through hole 555 of the main body 550 . The peripheral edge of the small-diameter bottom surface of the second seal portion 558 is coupled to the peripheral surface of the second operating portion 552 . The tip (lower end) of the first operating portion 551 protrudes downward from the lower surface of the main body 550 through the first through hole 554 (see FIG. 12B). On the other hand, the tip (lower end) of the second operating portion 552 is accommodated in the second through hole 555 and does not protrude downward from the lower surface of the main body 550 (see FIG. 12B). Here, since the first seal portion 557 and the second seal portion 558 are made of an elastic material (silicone rubber), they are elastically deformable. Therefore, the first operating portion 551 and the second operating portion 552 move upward when an upward force is applied, and thereafter, when the upward force is no longer applied, the elasticity of the first seal portion 557 and the second seal portion 558 increases. The force causes it to move downward and return to its initial state (the state shown in FIG. 12C).

The emergency lighting device 3 further includes a fixing member 56 (see FIGS. 5 and 6). The fixing member 56 is made of a metal plate that is resistant to rust, such as a stainless steel plate. The fixing member 56 includes a pentagonal fixing piece 560 whose longitudinal direction is the front-rear direction, a pair of leg pieces 561 that protrude upward from each side of both ends of the fixing piece 560 in the longitudinal direction, and an upper end of each leg piece 561 . It has a pair of mounting pieces 562 protruding so as to face the fixing piece 560 from the bottom. A fixing hole 563 for holding a nut is provided approximately in the center of the fixing piece 560 . A screw insertion hole 564 extends through one end (right end) of each mounting piece 562 (see FIG. 6).

Next, the procedure for assembling the emergency lighting device 3 will be described. However, the description of the work of assembling the emergency light source unit 4 and the control device 6 and the work of attaching the emergency light source unit 4 to the support member 7 will be omitted. Also, the assembly procedures (1) to (8) described below are merely examples, and the order of some assembly operations may be changed.

(1) Attachment of Second Gasket 54 to First Housing 51 First, an operator who performs assembly work attaches the second gasket 54 to the first housing 51 . Specifically, the operator fits the four projections 505 provided on the lower surface of the outer peripheral wall 510 of the first housing 51 into the four fitting holes 542 of the second gasket 54 one by one.

(2) Attachment of Third Gasket 55 to First Housing 51 The operator attaches the third gasket 55 to the first housing 51 by pushing the third gasket 55 into the inside of the projecting wall 518 (FIG. 7). reference). Inside the projecting wall 518 , three ribs 559 provided on the main body 550 are deformed so as to be crushed by the projecting wall 518 . As a result, the inside of the protruding wall 518 is sealed by the third gasket 55 , so that the first operation hole 502 , the second operation hole 504 and the display hole 503 provided in the outer peripheral wall 510 enter the first housing 51 . inundation will be suppressed. The tip (lower end) of the first operating portion 551 of the third gasket 55 protrudes from the surface (lower surface) of the outer peripheral wall 510 through the first operating hole 502 of the first housing 51 (see FIG. 13).

(3) Attaching the emergency light source unit 4 to the first housing 51 The operator inserts the lens body 440 of the emergency light source unit 4 into the window 501 of the first housing 51 through the opening 540 of the second gasket 54. Then, the plurality of ribs 517 of the first housing 51 are fitted into the corresponding fitting grooves 72 of the plurality of fitting grooves 72 of the support member 7 (see FIG. 9). Then, the operator inserts a screw into each of the three screw insertion holes 75 of the support member 7 and inserts each screw into the corresponding screw hole among the screw holes of the three first bosses 515 of the first housing 51. By screwing, the support member 7 is screwed to the first housing 51 . At this time, the two ribs provided on the upper surface of the peripheral wall 541 of the second gasket 54 are deformed by being crushed by the outer collar portion 441 of the lens 44 and the peripheral portion of the window 501 on the outer peripheral wall 510 . As a result, the window 501 of the first housing 51 and the outer flange 441 of the lens 44 are sealed by the second gasket 54, so that the gap between the holder 41 and the window 501 of the first housing 51 is closed and the window is closed. Ingress of water from 501 into the first housing 51 is suppressed. The first operating portion 551, the second operating portion 552, and the transmission portion 553 of the third gasket 55 face the insertion hole 70 of the support member 7 (see FIG. 9).

(4) Attaching the first gasket 53 to the first housing 51 2, the upper end portions of each of the inner walls 514 are press-fitted. Further, the operator presses the tip portion of the second boss 516 of the first housing 51 into the screw insertion hole 5311 of the fixing portion 531 of the first gasket 53 and inserts the second boss 516 into each fitting hole 5312 of the fixing portion 531 . 1 Each projection 519 of the housing 51 is fitted. Thus, the first gasket 53 is attached to the first housing 51 (see FIG. 9).

(5) Connection to the control device The operator presses the pair of power supply wires 80 for the normal power supply into the holes 5320 of the rear wire holding portions 532 of the two wire holding portions 532 of the first gasket 53. Hold (see FIGS. 18 and 19). Also, the operator presses and holds the pair of electric wires 81 for the emergency power supply into the holes 5320 of the front electric wire holding portion 532 of the two electric wire holding portions 532 of the first gasket 53 (see FIG. 18). ). The operator connects one end of the pair of power wires 80 to the input terminal block 603 of the control device 6 . Furthermore, the operator electrically connects one end of the pair of electric wires 81 to the receiving connector 64 of the control device 6 . Here, the control device 6 is accommodated in the housing 5 while being moved to one end (left end) in the longitudinal direction of the housing 5 . Therefore, the emergency lighting device 3 can secure a space for wiring the power supply line 80 and the electric wire 81 between the housing 5 and the control device 6 (see FIG. 19). Due to this space for wiring, the emergency lighting device 3 can improve the workability of the wiring work to the control device 6 .

(6) Incorporation of Control Device 6 into Second Housing 52 The operator accommodates the control device 6 inside the second housing 52 . At this time, the control device 6 is supported by the plurality of ribs 5204 of the second housing 52 (see FIG. 7).

(7) Assembling the housing 5 The operator inserts the tip (upper end) of the first boss 515 of the first housing 51 into the hole 5230 of the fixing part 523 of the second housing 52, and The tip (upper end) of the second boss 516 of 51 is inserted into the hole 5221 of the protrusion 5220 of the second housing 52 (see FIG. 7). At this time, the two wire holding portions 532 of the first gasket 53 are fitted into the corresponding recesses 5231 of the two recesses 5231 of the fixing portion 523 of the second housing 52 . Then, the operator inserts a screw into the hole 5230 of the fixing portion 531 from the upper surface side of the second housing 52 and screws the screw into the screw hole of the first boss 515 . Further, the operator inserts a screw into the hole 5221 of the projection 5220 from the upper surface side of the second housing 52 and screws the screw into the screw hole of the second boss 516 . That is, the first housing 51 and the second housing 52 are screwed together by two screws to form the housing 5 . Here, the pair of first inner walls 513 and the pair of second inner walls 514 of the first housing 51 and the pair of first side walls 521, the pair of second side walls 522 and the fixing portion 523 of the second housing 52 are It is sealed by the frame portion 530 of the first gasket 53 . In addition, the three ribs 5321 of the pair of wire holding portions 532 of the first gasket 53 are deformed so as to be crushed by the recesses 5231 of the fixing portion 523 of the second housing 52 . It seals a pair of recesses 5231 . Therefore, the first gasket 53 suppresses the ingress of water from the interface between the first housing 51 and the second housing 52 .

(8) Attaching the fixing member 56 to the housing 5 The operator puts the pair of mounting pieces 562 of the fixing member 56 on the projecting base portion 524 of the second housing 52, and inserts the screw insertion holes of each mounting piece 562. The screw inserted through 564 is screwed into the screw hole 5241 of the corresponding boss 5240 of the two bosses 5240 of the projecting base portion 524 . The fixing member 56 is attached to the housing 5 so that the fixing piece 560 faces the projection 524 of the second housing 52 (see FIGS. 13 to 16).

The assembly of the emergency lighting device 3 is completed through the procedure described above.

Here, the first operating portion 551 of the third gasket 55 faces the first operating member 6214 of the control device 6, and the second operating portion 552 of the third gasket 55 faces the second operating member 6215 of the control device 6. They face each other (see FIG. 17). Therefore, when the first operating unit 551 moving upward pushes the first operating member 6214 upward, the push button of the push button switch 611 is pushed by the first operating member 6214 to turn on the push button switch 611 . Also, when the second operating portion 552 moving upward pushes the second operating member 6215 upward, the push button of the push button switch 612 is pushed by the second operating member 6215 to turn on the push button switch 612 . In other words, the third gasket 55 seals the inner side of the projecting wall 518 while allowing the first operating member 6214 and the second operating member 6215 of the control device 6 to be pushed. Furthermore, the transmission portion 553 of the third gasket 55 faces the display element 613 and the light receiving element 614 through the insertion hole 70 of the support member 7 and two windows 6216 and 6217 provided in the case 62 of the control device 6. (See FIG. 17). Therefore, the light (green light) emitted by the display element 613 is emitted outside the case 62 through the window 6217 and then transmitted through the transmission portion 553 of the third gasket 55 to be emitted outside the housing 5 . Also, the control signal transmitted from the remote controller reaches the light receiving element 614 through the window 6216 of the case 62 after passing through the transmission portion 553 of the third gasket 55 . In addition, since the transparent portion 553 is formed sufficiently thinner than the main body 550 of the third gasket 55, the light emitted from the display element 613 and the control signal transmitted from the remote controller are attenuated when passing through the transparent portion 553. can be suppressed.

As described above, the second gasket 54 prevents water from entering the first housing 51 through the window 501 . In addition, the third gasket 55 prevents water from entering the first housing 51 through the first operation hole 502, the display hole 503, and the second operation hole 504, as described above. Further, the support member 7 restricts the displacement of the second gasket 54 and the third gasket 55 along the direction (vertical direction) in which the first housing 51 and the support member 7 are arranged. That is, since the displacement of the second gasket 54 is regulated by the support member 7 , the second gasket 54 is prevented from falling off from the peripheral portion of the window 501 of the first housing 51 . Similarly, since the displacement of the third gasket 55 is restricted by the support member 7 , it is prevented from coming off the projecting wall 518 of the first housing 51 . In this manner, the emergency lighting device 3 can simplify the structure of the waterproof first housing 51 .

Here, the support portion 533 of the first gasket 53 is arranged between each first inner wall 513 of the first housing 51 and the case 62 of the control device 6 in the housing 5 to support the control device 6. (See FIG. 17). Therefore, by supporting the control device 6 with the support portion 533 of the first gasket 53 , it is possible to suppress rattling of the control device 6 within the housing 5 .

Next, the procedure for assembling the lighting fixture 1 will be described. However, a description of the work of attaching the emergency power supply unit 9 to the instrument main body 10 is omitted. Also, the assembly procedures (1) to (3) described below are merely examples, and the order of some assembly operations may be changed.

(1) Attachment of Emergency Lighting Device 3 to Fixture Main Body 10 The operator attaches the emergency lighting device 3 to the fixture main body 10 before attaching the regular lighting device 2 .

However, the two power wires 80 (see FIGS. 18 and 19) held by the wire holding portion 532 on the rear side of the first gasket 53 are electrically connected to the power wires of the regular power supply when the lighting fixture 1 is installed. be done.

(3) Attachment of Regular Lighting Device 2 to Fixture Main Body 10 The operator inserts the upper portion of the regular lighting device 2 (the portion above the second fixing portion 241 of the two fixtures 24) into the fixture main body 10. . Then, the operator inserts the shaft of the driver into the recess 2215 of the cover portion 2214 of the right end member 221 , and passes it through the hole 2216 provided in the bottom wall of the recess 2215 . Tighten the mounting screw that is inserted into the . When the operator uses a screwdriver to tighten the mounting screw, the mounting screw is screwed into the screw hole 131 of the mounting piece 130 on the right side of the instrument body 10 . As a result, the second fixing portion 241 of the right fitting 24 is screwed to the right fitting piece 130 of the instrument body 10 . Subsequently, the operator inserts the shaft of the driver into the recess 2215 of the cover portion 2214 of the left end member 221, and passes it through the hole 2216 provided in the bottom wall of the recess 2215. Tighten the mounting screw inserted in 243 . When the operator uses a screwdriver to tighten the mounting screw, the mounting screw is screwed into the nut held in the fixing hole 563 of the fixing member 56 . As a result, the second fixing portion 241 of the left fixture 24 is screwed to the fixing piece 560 of the fixing member 56 . Finally, the operator closes the opening of the concave portion 2215 exposed on the surface of the cover portion 2214 with a tape or the like to cover it.
