  Next, an assembly procedure of the emergency lighting device X according to the present embodiment will be described. However, the pair of supports 6 is already attached to the main body 1.

  First, a worker who performs an assembling operation accommodates the lighting unit 4 in the main body 1 and fixes the casing 41 of the lighting unit 4 to the fixing piece 110 of the bottom plate 11 of the main body 1 by screwing (see FIG. 1). . Then, the worker attaches the light source unit 2 to the housing 41 of the lighting unit 4. Here, on the lower surface of the housing 41, two projections 411 that are individually inserted into the two round holes 2110 of the heat radiation member 21 are provided to project downward. That is, the operator positions the fixing portion 211 on the lower surface of the housing 41 by positioning the two protrusions 411 by individually inserting the two protrusions 411 into the two round holes 2110 provided in the fixing portion 211 of the heat radiation member 21. Put on. However, the worker inserts the fixing portion 211 between the fixed portion 12 and the lower surface of the housing 41 so that the fixed portion 12 of the main body 1 is below the heat radiating member 21 (see FIG. 3). Then, the operator turns the light source unit 2 into the lighting unit 4 by screwing the screw inserted into the screw insertion hole 120 of the fixed portion 12 into the first screw hole 2111 provided in the fixing portion 211 of the heat radiation member 21. (See FIG. 3). At this time, the plug connector 26 of the light source unit 2 is electrically and mechanically connected to the receptacle connector 408 disposed behind the central opening 410B of the housing 41. Note that, instead of the round hole 2110, a concave portion into which the projection 411 fits may be provided in the fixing portion 211.

  Subsequently, the worker accommodates the battery unit 3 in the main body 1. When the battery unit 3 is housed in the main body 1, the connector unit 32 of the battery unit 3 communicates with the connector on the receiving side of the lighting unit 4 through the opening 410 </ b> A provided in the housing 41 of the lighting unit 4. And mechanically connected. Here, a recess 412 is provided in a portion near the rear end of the right side surface of the housing 41 (see FIG. 4). Then, the projection 331 of the retaining portion 33 of the battery unit 3 is hooked on the concave portion 412 of the housing 41, so that the battery unit 3 is attached to the housing 41 of the lighting unit 4. The light source unit 2 was attached to the housing 41 of the lighting unit 4 by releasing the hook between the protrusion 331 and the concave portion 412 by pinching and bending the spring piece 330 of the retaining portion 33 with a finger. In this state, the battery unit 3 can be removed from the main body 1 by pulling it out.

  Finally, the operator inserts the pair of mounting springs 7 into the insertion grooves 13 provided on the front and rear sides of the inner peripheral surface of the main body 1, respectively, so that the lower surface of the main body 1 is closed. Is held by the main body 1 (see FIGS. 2C and 7A). As described above, the assembly of the emergency lighting device X according to the present embodiment is completed.

  Next, a procedure for replacing the battery unit 3 of the emergency lighting device X according to the present embodiment will be described.

  The operator performing the replacement work pulls the cover 5 downward against the spring force of the mounting spring 7. When the cover 5 is pulled downward, the mounting spring 7 moves downward in the insertion groove 13 while bending the pair of spring portions 70 toward each other, and the connecting portion 71 contacts the temporary holding portion 15 (temporary holding position). Position) (see FIG. 7B). Here, when the worker pulls the cover 5 downward, the hook portion 130 receives a downward stress from the spring portion 70 of the mounting spring 7, so that the main body 1 is also pulled downward. However, the place where the main body 1 receives the downward force (the hook portion 130) is located farthest in the horizontal plane from the place where the support 6 that supports the main body 1 with respect to the ceiling is fixed. For this reason, when the operator pulls the cover 5 downward, the possibility that the support 6 bends as the main body 1 comes out of the embedding hole is extremely low.

  Then, the operator removes the cover 5 by detaching the connecting portions 71 of the pair of mounting springs 7 from the temporary holding portions 15, and then grips the spring pieces 330 of the retaining portions 33 with fingers to form the protrusions 331 and the concave portions 412. The battery unit 3 is pulled out of the main body 1 in a state where the hook is released. Then, after accommodating the new battery unit 3 in the main body 1, the operator again inserts the mounting spring 7 into the insertion groove 13 and attaches the cover 5 to the lower surface side of the main body 1 by pushing up from below. The replacement of the battery unit 3 is completed as described above.

  By the way, when any trouble or the like occurs in the retaining portion 33 of the battery unit 3, there is a possibility that the battery unit 3 falls off from the main body 1 when the operator pulls down the cover 5. Therefore, in the emergency lighting device X according to the present embodiment, the distance from the lower surface of the main body 1 to the upper surface of the cover 5 when the connecting portion 71 of the mounting spring 7 is temporarily held by the temporary holding portion 15 of the main body 1. It is preferable that d5 be shorter than the height H1 of the battery case 31. Specifically, as shown in FIG. 8, it is preferable that the temporary holding portion 15 is provided at a height position on the inner peripheral surface of the main body 1 that satisfies the above condition (d5 <H1). In other words, even if the battery unit 3 comes off from the main body 1 when the cover 5 is pulled down, if the mounting spring 7 is temporarily held by the temporary holding portion 15 of the main body 1, the battery unit 3 becomes lower than the cover 5. Can be prevented from falling.

  Since the emergency lighting device X according to the present embodiment is configured as described above, the assembling work can be simplified as compared with a configuration in which the cover 5 is screwed to the main body 1 as in the conventional example. it can. Also, in the emergency lighting device X according to the present embodiment, the fixing position of the pair of supports 6 with respect to the main body 1 and the mounting position of the mounting spring 7 with respect to the main body 1 are in the normal direction of the front surface of the main body 1 (vertical direction). It is the most distant positional relationship. For this reason, in the emergency lighting device X according to the present embodiment, since the stress applied to the pair of supports 6 when the cover 5 is pulled down is reduced, there is a possibility that the support of the main body 1 by the supports 6 is released. It can be very low. Further, in the emergency lighting device X according to the present embodiment, since the pair of supports 6 are separately arranged near the battery unit 3 and the lighting unit 4 housed in the main body 1, the heavy battery unit 3 and the The lighting unit 4 can be reliably supported.

  Further, in the emergency lighting device X according to the present embodiment, the mounting spring 7 sets the distance d5 from the front end of the main body 1 to the cover 5 in a state where the connecting portion 71 is held by the temporary holding portion 15 to the battery case. It is preferable that the height of the main body 1 be shorter than the height H1 of the main body 1 along the depth direction (vertical direction).

  If the emergency lighting device X according to the present embodiment is configured as described above, even if the battery unit 3 comes off from the main body 1 when the cover 5 is pulled down, the battery unit 3 is received by the cover 5 and falls. Can be prevented.

  By the way, in the emergency lighting device X according to the present embodiment, two mounting springs 7 need not always be used. For example, as shown in FIGS. 9 and 10, one mounting spring 7 and one engaging portion 52 may be provided on the cover 5. However, the main body 1 is provided with the engaged portion 16 with which the engaging portion 52 is engaged as shown in FIG. That is, the engagement portion 52 and the engaged portion 16 constitute a so-called latch.

  The engaging portion 52 is a so-called striker, and its distal end portion is formed in a square tubular shape using a metal material or a synthetic resin material (see FIGS. 9 and 11). The engaged portion 16 is a so-called catch, and a pair of spring pieces 160 and a connecting piece 161 are integrally formed of the same type of material (metal material or synthetic resin material) as the engaging portion 52 (striker). It is composed. The pair of spring pieces 160 are configured such that the front ends (lower ends) are curved in a substantially U-shape, and the rear ends (upper ends) are connected to the connection pieces 161 (see FIG. 11). The connecting piece 161 is connected to the rear ends of the pair of spring pieces 160 so that the curved portions of the pair of spring pieces 160 face each other. The engaging portion 52 is inserted between the pair of spring pieces 160 from the tip (lower end) side, moves upward while bending the pair of spring pieces 160 away from each other, and finally moves the pair of spring pieces 160. Engage with the tip portion (curved portion) (see FIG. 11). Further, when the cover 5 is pulled down, the engaging portion 52 moves downward while bending the pair of spring pieces 160, and finally rides over the distal end portions of the pair of spring pieces 160, and engages with the engaged portion 16. The engagement is released.
