Has been done.

[0004]

[Problems to be solved by the device]

 With the portable container containing the above-mentioned identification, the rescuer knows the name, address, contact information, sex, age, blood type, presence or absence of a person who has encountered a disaster or accident, and promptly takes appropriate measures. However, there is a problem in that it is of little use to the wearer himself in the event of a disaster or accident.

Therefore, it is conceivable to attach a light emitting element such as the above-mentioned penlight to a portable container so that an object can be seen even in the dark or to notify a rescuer of the whereabouts of the portable person. It is also effective to attach a whistle to call the rescuer's attention. However, when the light emitting element is mounted on the portable container in this way, even if the light emitting element and the battery for supplying power to the light emitting element are indispensable, a switch for turning the light emitting element on and off Since it is necessary to attach a mechanism and an external operation unit for operating the switch mechanism, it is very difficult to form a small portable container with good portability.

Therefore, the present invention solves the above-mentioned problems, and a problem thereof is to provide a novel light-emitting device that can accommodate a light-emitting element, a battery, and a switch mechanism in a compact manner even in a small portable container with good portability. It is intended to provide a technology capable of constructing a portable container that is useful not only for rescuers but also for portable users by constructing a device and attaching the light emitting element to the portable container for identification as described above. . Another object of the present invention is to realize a new portable item which can notify the whereabouts of the wearer by both light and sound by attaching a whistle to the above-mentioned carrying container.

[0007]

[Means for Solving the Problems]

At the same time, a first connecting member having an insertion hole configured to insert the first electrode of the power source in a state where the first accommodating member and the second accommodating member are screwed together, and the first accommodating member. Is movably accommodated in the axial direction thereof, is conductively connected to the second terminal of the light emitting element, and moves in the same direction as the first connecting member moves in a direction opposite to the power source. Of the second connecting member configured in Is electrically connected to the second electrode of the power source in a state in which the first housing member and the second housing member are screwed together, and the contact surface facing the second connection member is connected to the power source. A third connecting member provided on the side, and an urging unit that urges the first connecting member and the second connecting member toward the power source side, and completes the first accommodating member and the second accommodating member. The first electrode pushes the first connecting member in a direction opposite to the power source so that the second connecting member and the third connecting member are separated from each other when screwed into the first housing member. By loosening the screwed state between the second housing member and the second housing member, the pressing state of the first electrode with respect to the first connecting member is relieved to bring the second connecting member and the third connecting member into contact with each other. It is a light-emitting device characterized by the above.

According to this means, when the first accommodating member and the second accommodating member are screwed together by the screw structure, when both are deeply screwed together, the first connection is made by the first electrode inserted into the insertion hole. The member is pressed and moves to the side opposite to the power source, and the second connecting member also moves in the same direction accordingly, so that the second connecting member and the third connecting member are separated from each other. Therefore, the circuit between the light emitting element and the power source is not configured, and the light emitting element is turned off. When the screwed state of the two is loosened, the pressing force of the first electrode is reduced, the first connecting member returns to the power source side, and the second connecting member moves to the power source side by the urging means and becomes the third connecting member. Upon contact, the light emitting element lights up.

According to this means, since the first connecting member and the second connecting member are arranged at the concentric position, these structures can be configured compactly and can be easily accommodated in the shaft-shaped device.

Further, when the screw structure is elastically mounted between the first connecting member and the second connecting member and the screwed state of the screw structure is loosened by a predetermined amount or more, the second connecting member is connected to the first connecting member. On the other hand, it is preferable to provide second urging means for moving the power source to the side opposite to the power source. According to this procedure, when the screwed state of the first connecting member and the second connecting member is loosened by a predetermined amount, the second connecting member is moved to the side opposite to the power source with respect to the first connecting member. The second connecting member is separated from the third connecting member again, and the light emitting element is turned off.

Further, it is preferable that the second accommodating member is provided with a sheet accommodating portion that accommodates a sheet-shaped member. According to this means, it is possible to store the sheet on which the identification etc. is written in the second storage portion, and it can be used as a portable container for emergencies.

Further, it is preferable that the third connecting member is screwed into the inside of the first accommodating member. According to this means, the position of the third connecting member can be easily changed depending on the degree of screwing. Therefore, the light emitting element is turned on / off and the first housing member and the second housing member are screwed together. The correspondence can be easily adjusted.

Further, it is preferable that the second accommodating member is provided with a whistle structure part having a blow-in port at an end thereof on the side opposite to the accommodating side of the power source. According to this means, it is possible to call the rescuer's attention in an emergency etc. by making a sound using the whistle structure section.

Both the first containing member 20 and the second containing member 40 are made of a conductor. The lithium battery 30 includes a first electrode 31 protrudingly formed on the upper end and a second electrode 32 formed on the outer peripheral surface of the battery body. The lithium battery 30 is inserted into the accommodation hole 44 in a state in which a resin sheet 50 on which an identification such as the name, address, contact information, sex, age, blood type, and anamnesia of the carrier is written is wound around the outer peripheral surface. ing. The lithium battery 30 is in conductive contact with the second housing member 40 at the lower end 32 a of the second electrode 32.

FIG. 2 is an enlarged view of the upper portion of the above embodiment. The light emitting portion 11 of the light emitting element 10 is inserted into the insertion hole 22 of the first accommodating member 20 from the accommodation hole 23 side, and the light emitting element 10 is formed by the step formed between the insertion hole 22 and the accommodation hole 23. Engaged. The first terminal 12 of the light emitting element 10 extends in the axial direction of the first accommodating member 20 and is inserted into a vertical groove 24a formed on the outer peripheral surface of the first connecting member 24 made of a conductor. Carbon grease is filled in the inside of the vertical groove 24a so that electrical continuity between the first terminal 12 and the first connecting member 24 is always ensured. A cylindrical sleeve 25 made of an insulating material is fixed to the outer periphery of the first connecting member 24.

A second connecting member 26 made of a conductor is fitted on the outer peripheral surface of the upper portion of the sleeve 25, and the sleeve 25 and the second connecting member 26 are configured to be slidable in the axial direction. A step 25a is formed on the lower outer peripheral surface of the sleeve 25, while a step 26a is formed on the outer peripheral surface of the intermediate portion of the second connecting member 26 and a step 26b is formed on the inner peripheral surface thereof. The outer surface of the lower expanded portion and the inner surface of the expanded portion of the second connecting member 26 below the step 26b are just fitted together.

A coil spring (biasing means) 27 is mounted between the bottom surface of the light emitting portion 11 of the light emitting element 10 and the step 25 a of the second connecting member 25. Here, the coil spring 27 is made of a conductor. Between the step 26b of the second connecting member 26 and the step 25a of the sleeve 25, a coil spring (second biasing means) 28 of about 1 to 2 turns is mounted.

An electrode insertion hole 24b is formed in the center of the first connection member 24 from the lower end thereof in the axial direction, and the first electrode 31 of the lithium battery 30 is inserted into the electrode insertion hole 24b. Has been done.

A third connecting member 29 made of a ring-shaped conductor is screwed into the female screw 23 a of the first accommodating member 20. A male screw 29a is formed on the outer circumference of the third connecting member 29, and concave grooves 29b are formed at two opposing positions on the lower end surface of the third connecting member 29. The groove 29b is for engaging the tip of a driver for screwing the third connecting member 29.

In the state of FIG. 2 in which the threaded portion 41 of the second housing member 40 is completely screwed into the lower end portion of the first housing member 20, the housing 48 is housed by the packing 48 attached to the outer periphery of the base of the threaded portion 41. The hole 23 and the accommodation hole 42 are sealed. In this state, the first electrode 31 of the lithium battery 30 is pushed upward with the first connecting member 24 inserted in the electrode insertion hole 24b, and this pushing force is applied to the spacer 25, the coil spring 26, and the Since the second connecting member 26 is pushed upward against the elastic force of the coil spring 27 by being applied to the coil spring 27 via the second connecting member 26, the lower end portion of the second connecting member 26 and the third connecting member 26 are connected. The member 29 is not in contact with the upper end surface (opposing surface) of the member 29, but is apart therefrom.

The first terminal 12 of the light emitting element 10 is conductively connected to the first electrode 31 of the lithium battery 30 via the first connecting member 24, and the second terminal 13 of the light emitting element 10 is a coil spring. It is conductively connected to the second connecting member 26 via 27. On the other hand, the second electrode 32 of the lithium battery 30 contacts the second housing member 40 at the lower end 32a, the second housing member 40 contacts the first housing member 20 at the screwing portion 41, and the first housing member 40 20 is in contact with the third connecting member 29 inside. Therefore, the third connecting member 29 is conductively connected to the second electrode 32 via the first accommodating member 20 and the second accommodating member 40.

In the state of FIG. 2 described above, since the second connection member 26 and the third connection member 29 are separated from each other, the first electrode 31 and the second electrode 32 of the lithium battery 30 and the first electrode of the light emitting element 10 are separated. The circuit formed between the terminal 12 and the second terminal 13 is open, and the light emitting element 10 does not light.

Next, as shown in FIG. 3, when the screwed state between the first housing member 20 and the second housing member 40 is slightly loosened, the first electrode 31 of the lithium battery 30 pushes it upward. In the first connecting member 24, the pushing force from the first electrode 31 is reduced or released by the first electrode 31 moving slightly downward in the electrode insertion hole 24b. It moves downward together with the sleeve 25, and accordingly, the second connecting member 26 also descends and comes into contact with the upper end surface of the third connecting member 29. When the second connecting member 26 and the third connecting member 29 come into contact with each other in this manner, the circuit is closed and the light emitting element 10 is turned on.

Next, as shown in FIG. 4, when the screwing state of the first housing member 20 and the second housing member 40 is further loosened, the first electrode 31 of the lithium battery 30 is further lowered and the first connection is made. The member 24 and the sleeve 25 also descend, but the elastic force applied to the second connecting member 26 of the coil spring 27 weakens accordingly, and eventually the elastic force of the coil spring 28 relatively increases, so that the first connecting member The second connecting member 26 moves upward with respect to 24 and the sleeve 25 by the elastic force of the coil spring 28. Therefore, the lower end portion of the second connecting member 26 and the upper end surface of the third connecting member 29 are separated from each other again, and the light emitting element 10 is turned off.

In the above-described embodiment, the second connecting member 26, the coil spring 27, and the inner surface of the first housing member 20 correspond to the first electrode 31 of the lithium battery 30 and the electrode insertion hole of the first connecting member 24. Although they are formed so as not to come into contact with each other when inserted in 24b, in order to ensure completeness, insulation is provided between the second connecting member 26 and the coil spring 27 and the inner surface of the first accommodating member 20. It is desirable to form layers.

In this embodiment, the inscription is wrapped around the outer periphery of the main body of the lithium battery 30 and inserted into the accommodation hole 42 of the second accommodation member 40, and the first accommodation member 20 and the second accommodation member 40 are screwed together. As a result, it can be used as a portable container for storing identification documents in case of emergency, and it can inform the rescuer of the identity information of the carrier in the event of a disaster or accident. Also, since it can be used as a whistle that can be blown by blowing air through the blow-in port 47, the rescuer's attention can be called when the person is trapped in various places during a disaster. Further, by turning on the light emitting element 10, it is possible to illuminate the hand even in the dark, and it can also be used as a signal light for alerting a rescuer.

In this embodiment, when the first housing member 20 and the second housing member 40 are tightly screwed together as shown in FIG. 2, the light emitting element 10 is turned off, and as shown in FIG. Since the light emitting element 10 can be turned on by loosening the screwed state, the light emitting element 10 can be operated by the screwing structure for accommodating the identity information, and the operability is good and Since it is not necessary to separately provide an operation switch for turning on and off the light emitting element 10, the entire device can be made compact.

In particular, if the screwed state is further loosened from the above lighting state, the light can be surely turned off as shown in FIG. 4, so that the light is turned on only within a predetermined screwed state range. Therefore, there is no fear of inadvertently continuing to turn on the light due to loosening of the screwed part, and battery consumption can be prevented.

Since the third connecting member 29 is screwed into the female screw 23 a formed continuously inside the first accommodating member 20, the position can be freely adjusted in the axial direction. It is possible to easily perform the adjustment work between the screwed state of the first housing member 20 and the second housing member 40 and the lighting / extinguishing state of the light emitting element 10. For example, the rotation angle of the screwed portion from the light-off state shown in FIG. 2 to the light-on state shown in FIG. 3 is 90 to 120 degrees, and the light-off state shown in FIG. It is preferable that the rotation angle before the start is about 360 degrees.

Further, since the female screw 23a of the first housing member 20 is also a female screw with which the screwing portion 41 of the second housing member 40 is screwed, the structure is simple and the manufacturing cost can be reduced. Further, since the first connecting member 24 and the second connecting member 26 are arranged concentrically with each other, even the small and thin shaft-shaped device as described above can be easily incorporated, and at the same time, the mutual connection can be achieved. Insulation between them is also easy.
