  As shown in FIGS. 1 and 2, the mainspring winding tool 9 includes a gear 6 meshed with the central shaft 17 of the mainspring 5, one end fixed to the gear 6, and the other end penetrating the casing 4 and projecting outside. The fixed shaft 18, the base piece 19 fixed to the other end of the fixed shaft 18, and the operation handle 20 provided so as to be swingable with respect to the base piece 19 are provided. According to such a configuration, when the user picks the operation handle 20 and rotates it around the fixed shaft 18, the gear 6 fixed to the fixed shaft 18 rotates and the central shaft 17 meshed with the gear 6. The mainspring 5 is wound up by rotating. Further, after the winding of the mainspring 5, the details are not shown in the figure, but the operation handle 20 is tilted so as to form an angle of about 90 ° with respect to the base piece 19, and the recess formed on the front surface of the casing 4 is formed. By storing the flashlight main body 3 in the wall holder 2, the operation handle 20 does not interfere with the wall holder 2 by being housed in the portion 21.

  As shown in FIGS. 2 and 3, the start switch mechanism 10 is in close contact with the peripheral surface of the flywheel 7 and the trigger detector 22 provided so as to be rotatable about the base, and prohibits its rotation or rotation. A brake shoe 23 that is spaced apart from the surface and allows rotation thereof, and a connecting link 24 that connects the trigger detector 22 and the brake shoe 23 are provided. According to such a configuration, the rotation of the trigger detector 22 is transmitted to the brake shoe 23 while the direction of motion is changed by the connecting link 24, so that the brake shoe 23 is in close contact with the peripheral surface of the flywheel 7. They are separated.

  The forget-to-wind prevention mechanism 11 includes a mainspring interlocking link 25 that interlocks with the winding or relaxation of the mainspring 5 and a movable lid 26 that covers or exposes the trigger insertion hole 15. As shown in FIG. 2, the movable lid 26 is a long flat plate-like member, and one end side thereof is formed in an oval shape larger than the trigger insertion hole 15, while the other end side is formed in a substantially rectangular shape. A link insertion hole 27 is formed through. The movable lid 26 configured in this manner is rotatably supported by a support shaft 28 protruding from the bottom surface of the casing 4. Further, the other end of an urging spring 29 having one end fixed to the casing 4 is fixed to a portion of the movable lid 26 on the trigger insertion hole 15 side with the support shaft 28 interposed therebetween. Thus, when no external force is applied, the movable lid 26 is held in a state of covering the trigger insertion hole 15 by rotating by receiving the biasing force of the biasing spring 29 and coming into contact with a positioning rib (not shown). The

  On the other hand, the mainspring interlocking link 25 is a long rod-shaped member, as shown in FIG. 2, and one end side thereof is bent to form a mainspring abutting portion 30 for abutting against the mainspring 5. A lid pressing portion 31 for pressing the movable lid 26 is formed on the other end side. The mainspring interlocking link 25 is rotatably supported by a support shaft 32 protruding from the back surface of the casing 4. Further, the mainspring interlocking link 25 is moved downward on the lid pressing portion 31 side by fixing the other end of the urging spring 33 whose one end is fixed to the casing 4 to the lid pressing portion 31 side from the support shaft 32. Is being energized. With such a configuration, when the mainspring 5 is wound up and the diameter is reduced, the mainspring interlocking link 25 causes the mainspring contact portion 30 to follow the mainspring 5 by the urging force of the urging spring 33, that is, the mainspring contact. It rotates so as to raise the contact portion 30. As a result, the lid pressing portion 31 descends and rotates by pressing the movable lid 26. On the other hand, when the mainspring 5 relaxes and the diameter increases, the mainspring interlocking link 25 causes the mainspring abutting portion 30 to receive a pressing force from the mainspring 5 to resist the urging force of the urging spring 33. It rotates so that the contact part 30 may be lowered. As a result, the lid pressing portion 31 is raised and separated from the movable lid 26.

  FIG. 5 is a view for explaining in more detail how the mainspring interlocking link 25 presses and rotates the movable lid 26, and shows a cross section taken along line AA in FIG. As shown in FIG. 5, the link insertion hole 27 of the movable lid 26 is formed as a guide surface 34 whose one end is inclined, and a portion of the lid pressing portion 31 that contacts the guide surface 34 is formed in an arc shape. As a result, when the mainspring interlocking link 25 rotates and the lid pressing portion 31 descends, the arc-shaped portion of the lid pressing portion 31 comes into contact with the guide surface 34 of the movable lid 26 as shown in FIG. Thereafter, as shown in FIG. 5B, the lid pressing portion 31 is further lowered so that the arc-shaped portion is guided by the guide surface 34, so that the movable lid 26 that receives the pressing force from the lid pressing portion 31. Moves to the right in FIG. 5 against the biasing force of the biasing spring 29. Further, when the mainspring interlocking link 25 rotates from the state of FIG. 5B and the lid pressing portion 31 rises, the movable lid released from the pressing force of the lid pressing portion 31 as shown in FIG. 26 moves to the left by the urging force of the urging spring 29. In this way, the movable lid 26 is rotated in conjunction with the rotation of the mainspring interlocking link 25.

  The wall-hanging holder 2 is for attaching the flashlight body 3 to a wall surface (not shown). As shown in FIG. 1, the wall holder 2 is a casing having an upper opening, and a screw (not shown) is inserted through a screw insertion hole 35 formed in the back surface 2a with the back surface 2a in close contact with the wall surface. It is fixed with. Further, a notch 36 is formed on the front surface 2b of the wall holder 2 for avoiding interference with the grip portion 12 when the flashlight body 3 is mounted. Furthermore, a trigger 37 having a predetermined height is projected from a position inside the bottom portion of the wall holder 2 at a position corresponding to the trigger insertion hole 15 of the flashlight body 3.

  The emergency flashlight 1 configured as described above is in a state in which the flashlight main body 3 is mounted on the wall-hanging holder 2 in normal times other than emergency. That is, as shown in FIG. 1, the flashlight main body 3 is inserted into the wall-mounted holder 2 from the bottom side in a state where the mainspring 5 in the flashlight main body 3 is completely wound up by the mainspring winding tool 9. At this time, the trigger 37 of the wall-mounted holder 2 is inserted into the inside of the trigger insertion hole 15 of the flashlight body 3 and the trigger detector 22 is pushed up, so that the trigger detector 22 rotates with its base end as a fulcrum. . The rotation of the trigger detector 22 is transmitted to the brake shoe 23 via the connecting link 24, so that the brake shoe 23 comes into close contact with the peripheral surface of the flywheel 7 and prohibits its rotation. Thereby, the mainspring 5 meshed with the flywheel 7 through the gear 6 cannot be relaxed and is held in a wound state.

  Here, the trigger 37 can be inserted into the casing 4 from the trigger insertion hole 15 only when the mainspring 5 is completely wound up. More specifically, when the mainspring 5 is not completely wound up, the mainspring 5 relaxes and widens in the casing 4, so that the mainspring interlocking link 25 has the mainspring abutment portion 30 pressed by the mainspring 5. Thus, the mainspring abutting portion 30 is rotated so as to be lowered against the urging force of the urging spring 33. As a result, the lid pressing portion 31 of the mainspring interlocking link 25 is lifted and separated from the movable lid 26, and the movable lid 26 is held in a state of covering the trigger insertion hole 15 by receiving the biasing force of the biasing spring 29. Is done. Therefore, the trigger 37 cannot be inserted into the casing 4. On the other hand, when the mainspring 5 is completely wound up, the mainspring 5 is reduced in the casing 4, and the mainspring interlocking link 25 receives the urging force of the urging spring 33 to follow the reduction of the mainspring 5. It rotates to raise the contact part 30. Accordingly, the lid pressing portion 31 of the mainspring interlocking link 25 is lowered and inserted into the link insertion hole 27 of the movable lid 26. At this time, the movable lid 26 that has received the pressing force from the lid pressing portion 31 rotates counterclockwise as shown in FIG. 3, and the trigger insertion hole 15 is exposed. Thereby, the trigger 37 can be inserted into the casing 4. As described above, when the mainspring 5 is not completely wound up, the trigger 37 of the wall-hanging holder 2 is inserted into the trigger insertion hole 15 of the flashlight main body 3 even if the flashlight main body 3 is to be mounted on the wall-hanging holder 2. Therefore, the flashlight body 3 cannot be mounted on the wall holder 2. As a result, it is possible to prevent malfunction from occurring in an emergency due to an artificial mistake such as forgetting to wind the mainspring 5.

  On the other hand, when the flashlight body 3 is detached from the wall holder 2 in an emergency, the trigger 37 of the wall holder 2 is pulled out from the casing 4 of the flashlight body 3 so that the trigger detector 22 is released from the pushing force of the trigger 37. Then, the state returns to the state shown in FIG. The rotation of the trigger detector 22 is transmitted to the brake shoe 23 via the connecting link 24, and the brake shoe 23 is separated from the peripheral surface of the flywheel 7, so that the flywheel 7 becomes rotatable. As a result, the mainspring 5 meshed with the flywheel 7 via the gear 6 is released from the holding force of the brake shoe 23 and relaxed, and spreads greatly in the casing 4. At this time, the urging force stored in the mainspring 5 is released, the central shaft 17 of the mainspring 5 is rotationally driven, and this rotational driving force is transmitted to the generator via the flywheel 7 to start the generator. To do. The electric power generated by the generator is sent to the battery for charging, and the LED lamp 8 is turned on when electric power is supplied from the battery to the LED lamp 8. Thereby, the LED lamp 8 is turned on simultaneously with the removal of the flashlight main body 3 from the wall holder 2, and the flashlight main body 3 can be used immediately. Also, if necessary, the lighting switch 16 shown in FIG. 1 is turned off to turn off the LED lamp 8, thereby saving power consumption and using the flashlight body 3 for a longer time. In addition, when the battery is discharged, if the spring 5 is released by releasing the mainspring 5 using the mainspring winding tool 9, the generator is activated and the battery is charged. The electric lamp body 3 can be put into a usable state. In addition, if the mainspring winding tool 9 and the lighting switch 16 are used appropriately, the flashlight body 3 can be used other than in an emergency.

  In this embodiment, the LED lamp 8 with low power consumption is used as the illumination lamp according to the present invention. However, the present invention is not limited to this, and an arbitrary illumination device can be used. Further, in this embodiment, a battery is interposed between the generator and the LED lamp 8, but this battery is not an essential constituent element of the present invention, and power may be directly supplied from the generator to the LED lamp 8. Is possible. However, as in this embodiment, of the power generated by the generator, surplus power is supplied to the battery without being supplied to the LED lamp 8, and the illumination switch 16 is operated as necessary to operate the LED lamp 8 Turning off / lighting the lamp has an advantage that the flashlight body 3 can be used for a longer time by using the biasing force released from the mainspring 5.

  The present invention can be applied not only to a flashlight provided with an illumination lamp but also to a crime prevention device that emits an alarm sound at the same time that it is removed from a holder.
