Description

The present invention relates to a signal lamp using a dry battery, a structure of a battery holder for supplying power by attaching a battery to a flashlight or other device, and a signal lamp including the battery holder. More specifically, the AA battery (hereinafter referred to as “AA battery”) and the AA battery (hereinafter referred to as “AA battery”).
Both of these relate to applicable battery holders and signal lamps. Note that the dry battery includes not only a disposable dry battery but also a rechargeable battery having the same size as the AA battery and the AA battery.

In general, lighting devices such as a signal light and a flashlight used for traffic guidance by police officers and guards use a single battery as a power source. This is because a single battery has a large weight, and an AA battery has a small power, so the number of the batteries increases, and the device itself becomes heavy. In such devices, battery exhaustion is the biggest problem, but it is important to secure a spare battery especially for a signal light that is generally used for a long time outdoors. A dry battery is a power source that is relatively easy to obtain, but if the required number of AA batteries are not available when needed, the device itself cannot be used. On the other hand, AA batteries are used in a wide range of equipment other than lighting equipment, and are easier to obtain than AA batteries.

Focusing on this point, a prior art has been proposed for enabling use of a battery having a different standard in a single device. For example, the spacer for a dry battery described in Patent Document 1 is a battery that can be used with a flashlight for a single battery by inserting the single battery into a spacer having the outer dimensions of the single battery. Moreover, the battery seating structure described in Patent Document 2 is provided with an electrode that deforms in accordance with the overall length of the battery in a case that can hold a plurality of standard batteries. On the other hand, the multi-standard battery-compatible flashlight described in Patent Document 3 includes a battery loading cylinder having battery holding pieces corresponding to batteries of different diameters and a mechanism for moving the negative electrode contact terminal according to the length of the battery. Yes. Furthermore, the flashlight described in Patent Document 4 allows replacement of batteries from a single type to a single type by changing a sleeve corresponding to the standard of the battery.

However, the dry cell spacer according to Patent Document 1 is a separate part from the battery, and there is a risk of losing it with the equipment even when it is not needed. The battery seating structure according to Patent Document 2 is a structure in which a battery is loaded perpendicularly to its axis, so that a battery housing portion is provided in a cylindrical handle portion such as a signal light or a flashlight. Is difficult to apply. The multi-standard battery-compatible flashlight according to Patent Document 3 has a structure in which a battery loading cylinder having a complicated structure is housed, so that the cost is high and breakage or malfunction is likely to occur due to impact or the like. The flashlight according to Patent Document 4 has a problem that the sleeve needs to be replaced according to the battery standard, and the handling becomes complicated.

The present invention was created for the purpose of solving the problems of the prior art,
In general, a signal lamp or flashlight in which AA batteries are used, a battery holder structure that can also use AA batteries without using special separate parts and complicated internal structures, and a signal light having the same It is an issue to provide. In the first place, commercial signal lights and flashlights are assumed to be used outdoors for a long time, and it is assumed that AA batteries are difficult to obtain immediately. In many cases, it is considered that the problem of running out of the battery can be solved by providing compatibility with the battery.

  In order to solve such a problem, the invention described in claim 1 is a structure of a battery holder for supplying power by attaching a battery to a signal light, a flashlight or other device using a dry battery, and at least one end of the battery holder is supplied. A battery housing cylinder that is fixed to the apparatus main body and whose other end can be sealed with a cap, a positive electrode plate that is provided so that a positive electrode of the battery abuts on one end side of the battery housing cylinder, and a spring-shaped current-carrying body on the cap A negative electrode plate provided so that the negative electrode of the battery is in contact with the battery, and the battery housing cylinder can hold an AA battery or an AA battery in parallel by a plurality of holding bodies provided on the inner surface thereof. The positive electrode plate can contact the positive electrode of one AA battery or two AA batteries in parallel, and the negative electrode plate can contact the negative electrode of one AA battery or two AA batteries in parallel. Featuring a configuration with possible contacts

  Further, the invention described in claim 2 is the structure of the battery holder according to claim 1, wherein the holding body is a strip-shaped convex portion, and the battery housing cylinder is provided on the inner surface at equal intervals. The eight holders can hold one AA battery or two AA batteries in parallel.

  The invention described in claim 3 is the structure of the battery holder according to claim 1 or 2, wherein the positive electrode plate can be fitted with a positive electrode of a single battery on its surface. It is characterized by comprising a positive electrode holder provided with side holes into which the positive electrode of each AA battery can be fitted to the left and right of the center hole.

  Further, the invention described in claim 4 is the structure of the battery holder according to any one of claims 1 to 3, wherein the negative electrode plate has eight pole projections on the surface of a plate body made of a current-carrying member. It is characterized by being circularly arranged at intervals.

  The standard sizes of the diameter and height (length) of the dry cell are 26.2 mm and 50.0 mm for the AA batteries, and 14.5 mm and 50.5 mm for the AA batteries, respectively. That is, the diameter of the AA battery is slightly more than half that of the AA battery, and the difference in height (length) is only 0.5 mm. Therefore, two AA batteries arranged in parallel can be accommodated in a battery housing cylinder having an inner diameter slightly larger than the diameter of one AA battery. In addition, when the positive electrode of the battery is fixed in contact with the positive electrode plate of the battery holder, the negative electrode plate that contacts the negative electrode of the battery has a mechanism that absorbs the difference in height (length) between the AA batteries and the AA batteries. If provided, the battery can be energized regardless of which battery is loaded.

  According to said structure, the cap of an other end side can be removed and a battery can be loaded in a battery accommodating cylinder, and the front-end | tip of the several holding body provided in the inner surface of a battery accommodating cylinder follows the outer periphery of a single battery. By arranging the AA batteries, it is possible to hold the AA batteries. On the other hand, when the AA batteries, which are a little more than half the diameter of the AA batteries, are arranged side by side, the outer periphery fits between two adjacent holding bodies Is held. When the positive electrode of the AA battery is fixed in contact with the positive electrode plate, the negative electrode plate in contact with the negative electrode of the battery compresses the spring-like current-carrying member, and the height (length) is slightly shorter. When the positive electrode is fixed to the positive electrode plate, the spring-shaped current-carrying body extends due to its elasticity, so that the negative electrode plate also comes into contact with the negative electrode of the battery. State. The batteries to be loaded may be one AA battery and two AA batteries arranged in parallel, or by extending the battery housing cylinder, two AA batteries and four AA batteries arranged in parallel may be connected in series. Furthermore, the number of batteries can be further increased by combining the same units.

  In addition, even when the number of batteries in series is increased by making the holding body into eight strip-shaped convex portions provided at equal intervals on the inner surface of the battery housing cylinder, All of the batteries are also stably held by the holding body, and it is possible to prevent loose contact in the battery housing cylinder due to vibration or the like during use of the device, thereby causing poor contact.

  In addition, the positive electrode plate is provided with a positive electrode holding body provided with side holes into which the positive electrode of each AA battery can be fitted to the left and right of the central hole into which the positive electrode of the AA battery can be fitted. Therefore, when the AA battery is loaded, the positive electrode is fixed by the center hole, and when the AA battery is loaded in parallel, the positive electrode of each AA battery is fixed by the side hole. It is prevented that the positive electrode is displaced from the positive electrode plate due to vibration or the like at the time of use, causing poor contact.

  Sealing the other end of the battery housing cylinder with the cap attached with the negative electrode plate may be either a fitting type or a screw-in type, but both the AA batteries and AA batteries are loaded, the vicinity of the center of the negative electrode of the battery It is desirable that the negative electrode plate abuts securely. Here, by configuring the negative electrode plate so that eight pole protrusions are circularly arranged at equal intervals on the surface of a plate body made of a current-carrying member, all the pole protrusions are also loaded when a single battery is loaded, Even when AA batteries are loaded in parallel, at least one of the pole protrusions will surely contact the negative electrode.

  According to the structure of the battery holder according to the present invention, power can be supplied regardless of whether the AA battery or AA battery is loaded. Even when two batteries are not available, if there is a required number of AA batteries, it is possible to load them and continue using the device. Compared to AA batteries, it is relatively easy to obtain and reserve AA batteries, which are often stocked, can be used, especially when used outdoors or in emergency situations. It contributes to the improvement of safety by using signal lights and flashlights.
