Description

  The present invention relates to a safety light for a cut cone mounted on an upper part of a truncated cone-shaped cut cone disposed on a road construction site or the like.

  Conventionally, a truncated cone-shaped cut cone placed on a dark construction site such as a night road construction site is equipped with a safety light 1 as shown in FIG. Visibility is enhanced.

  Such a security light 1 is mounted on the top surface portion of a cut cone 2 in which a circular through hole 2a as shown in FIG. 6 is formed.

  As shown in FIG. 6, the security light 1 includes a columnar insertion portion 12 that can be fitted into the through-hole portion 2 a of the cut cone 2, and a bottom surface portion 11 a having a diameter larger than the diameter of the columnar insertion portion 12. And an exposed portion 11 having

  The insertion portion 12 is provided with a convex portion 12a. The convex portion 12a is aligned with the position of the concave portion 2b formed on the top surface portion of the cut cone 2, and the insertion portion 12 is cut from the through-hole portion 2a to the cut cone 2. If the whole of the safety light 1 is slightly rotated after that, even if the cut cone 2 falls down for some reason, it is possible to prevent the safety light 1 from coming off the cut cone 2.

  Inside the exposed portion 11, a light emitting device having a configuration as shown in FIG. In FIG. 7, reference numeral 22 denotes a power supply device. The power supply device 22 stores the power output from the solar cell 21 in a chargeable / dischargeable battery 23, and the power output from the battery 23 is used for the light emission control device 25, LED, and the like Is supplied to the light emitter 24.

  The light emission control device 25 controls the blinking of the light emitter 24 using the power supplied from the power supply device 22. Here, the configurations of the light emission control device 25 and the power supply device 22 are the same as those used in the safety light for cut cones already sold by the applicant of the present application under the name of “Solara (registered trademark) radio selenite”. The configuration is the same as that of the device and the power supply device.

  In the conventional safety light 1 having the above-described configuration, the power generated by the solar battery 21 is stored in the battery 23. Therefore, the security light 1 can be operated over a long period of time.

  However, if the amount of power output from the solar cell 21 decreases due to a cloudy day or the like, the amount of power stored in the battery 23 decreases and the operation of the safety light stops. In such a case, it is necessary to replace the battery 23 stored in the safety light 1 with a battery that is sufficiently charged elsewhere.

  In such a case, in the conventional example, as shown in FIG. 8, the lid member 13 locked to the bottom of the insertion portion 12 by the convex portion 13 a is removed from the insertion portion 12, and the inside of the insertion portion 12 is removed. The stored battery holder 14 is taken out from the insertion portion 12, and the stored battery is replaced with a new charged battery.

  As shown in FIG. 9, the battery holder 14 is supported inside the insertion portion 12 by a recess 12b formed in the insertion portion 12 and two support legs 12c. Further, the convex portion 13 a of the lid member 13 engages with the protrusion 12 d formed on the bottom portion of the insertion portion 12 to lock the lid member to the bottom portion of the insertion portion 12. The battery holder 14 is sandwiched between the lid member 13 locked to the bottom of the insertion portion 12 and the bottom surface portion 11a (see FIG. 8) of the exposed portion 11 on the opposite side. In this way, with the battery holder 14 sandwiched between the lid member 13 and the bottom surface portion 11a, the battery housed in the battery holder 14 and the power supply device 22 disposed in the exposed portion 11 (see FIG. 7). The electrical connection is maintained.

  Here, in the conventional example configured as described above, when the battery 23 accommodated in the battery holder 14 is replaced, the lid member 13 locked to the bottom of the insertion portion 12 is removed and then inserted. It is necessary to take out the battery holder 14 inside the portion 12 from the insertion portion 12 and replace the stored battery.

  Such a battery replacement operation is performed outdoors, such as on a road where a cut cone is installed, with an operator standing.

  When the worker performs such a battery replacement operation, the worker usually holds the insertion portion 12 of the safety light removed from the cut cone with one hand H2, as shown in FIG. The battery 23 housed in the battery holder 14 is replaced while the cover member 13 is held with the hand H1. At this time, the worker performs the battery replacement work while holding the battery holder 14 with his / her finger, and often the lid member 13 falls from the worker's hand H1 and falls on the road.

  When such a situation occurs, the lid member 13 is small and lightweight, so it rolls over the road and enters a side groove or hits a running car and is lost. There were many times.

  If the lid member 13 is lost as described above (see FIG. 10B), the battery holder containing the new battery cannot be fixed inside the insertion portion 12. There was a problem that the lamp itself could not be used.

  That is, the conventional safety light has a problem that the lid member is easily lost when the battery is replaced, and in such a case, the safety light itself becomes unusable.

  In order to solve the above problems, the present invention is a truncated cone-shaped cut cone placed on a road construction site or the like, and has a circular through-hole at the center of the top surface of the cone. In a safety light for a cut cone having a built-in light emitter and a power source, the safety light is disposed at a columnar insertion portion that can be fitted into a through hole portion of the cut cone, and an upper portion of the insertion portion. A battery that detachably accommodates the battery that constitutes the power source at the center of the bottom surface of the exposed portion. The holder is fixed so as to extend downward, and is a cylindrical member that constitutes the insertion portion, and has a bottomed cylindrical shape that has a bottom portion and can store the battery holder therein. On the opening side of the upper part of the battery case, the dew It is characterized in that the engagement portion engaged detachably to the bottom portion of the part is arranged. Here, the battery holder may be provided with a string-like member that can be held between the battery holder and the battery stored when the battery is stored.

  According to the present invention, when replacing the battery stored in the interior, two separate components can be formed, and the two batteries are securely held in both hands. Since the replacement can be performed, it is possible to provide a safety light for a cut cone that can be replaced without risk of losing the components.
