Description

  The present invention relates to a tool for assisting the operation of a breaker for preventing overcurrent, leakage, etc. in a house or the like.

  In a building such as a house where electricity can be used, a breaker is installed to prevent overcurrent, electric leakage, and the like. FIG. 12 shows a configuration of a general breaker 100, in which an earth leakage breaker 101, a safety breaker 102, and an amper breaker 103 are arranged except for some areas. The earth leakage breaker 101 is an apparatus that automatically cuts off electricity when a leakage of electric appliances or indoor wiring is detected, or when a current exceeding a certain level flows. The safety breaker 102 is provided for each of a plurality of circuits divided in the building, and when the use of electricity exceeding the capacity, a short circuit, or the like is detected, only the circuit is cut off and the power failure of the entire building is prevented. Is. The ampere breaker 103 is a device that shuts off when a current exceeding the amount of current contracted with the power company flows. 13A and 13B show a general configuration of the earth leakage breaker 101, which includes a lever switch-like handle 105 that slides up and down, an earth leakage display button 106, and a test button 107. Yes. When the handle 105 is positioned upward as shown by a solid line in FIG. 13B, the handle 105 becomes “ON”, that is, it can be energized. When the handle 105 is positioned downward as shown by a one-dot chain line in FIG. , “OFF”, that is, an electric cutoff state. The electric leakage display button 106 is normally pressed (not protruding), but when electricity is cut off due to electric leakage, it is indicated by a broken line in FIG. It will be in a state protruding. Further, depending on the type of breaker, as indicated by a two-dot chain line in FIG. 13B, the handle 105 trips to a neutral position and cannot be turned “on” unless it is turned off once. If the thing or the earth leakage display button 106 protrudes, the handle 105 may not be turned “on” until the button 106 is pressed.

Since the breaker as described above is usually installed at a high place and is forced to operate in the dark when the electric power is interrupted at night, a tool for assisting the operation is highly necessary. In addition, since it is rarely operated, dust tends to accumulate, and many people are hesitant to touch the handle directly with their hands because of fear of electric shock. The following prior art is disclosed as a solution to such a problem. In this prior art, each handle of the breaker and the drawstring are connected by a predetermined coupling tool, and the drawstring is suspended from the breaker box, and this causes the breaker to be in a “cut” state and a power failure occurs. In addition, the handle can be restored to the “ON” state by pulling the pull string (see Patent Document 1).
Japanese Patent Application No. 11-297182

  However, in the configuration disclosed in Patent Document 1, only the operation of changing the handle from “OFF” to “ON” can be performed. For this reason, after turning off the handle, the handle trips to a neutral position and must be turned “off” before it can be turned “on”, and the handle must be turned “on” only after the earth leakage display button is pressed. For types of breakers that cannot be applied, the application is insufficient or impossible. In addition, since it is often forced to operate in the dark at the time of a power failure, it may be difficult to find the drawstring even if the drawstring is present.

  Therefore, an object of the present invention is to enable a safe and simple operation in a tool that assists the operation of the breaker, adapting to various situations and breaker types.

In order to achieve the above object, a breaker operating rod for assisting operation of a breaker according to the present invention includes a rod-shaped member constituted by two rod-shaped components, and one rod-shaped component is gripped at one end. A first connecting portion that can be connected to the other rod-shaped component is formed at the other end, and the other rod-shaped component is connected to the first connecting portion at one end. The second connecting portion is formed, and includes one roller rotatably supported by a pair of fixed pieces extending in the axial direction at the other end, and provided on the one rod-shaped component member. The first connecting portion and the second connecting portion provided on the other rod-shaped component are connected so that the angle formed between them can be adjusted.

  According to this configuration, when operating the breaker handle, button, etc., the breaker operating rod is applied to the object to be operated, and the breaker operating rod is operated so as to roll the roller. The desired operation can be executed. Thereby, it can be used particularly effectively when the breaker at a high place cannot be reached, and since the hand is not touched directly, the fear of electric shock can be reduced. Furthermore, since it is not necessary to install equipment for each breaker, it is economically superior.

In addition, the bar-shaped member is composed of two bar-shaped structural members, and these bar-shaped structural members are connected so that the angle formed between the adjacent bar-shaped structural members can be adjusted, so that the operability can be improved. For example, by forming a chrysanthemum at the connecting portion of each rod-shaped component member, adjacent rod-shaped component members can be coupled firmly and adjustable in angle.

In the above-described configuration, it is preferable that the light emitting device is fixed to the rod-like member via a predetermined fixing means .

  As described above, since the light emitting device such as the flashlight is fixed to the rod-like member, the operation in the dark can be executed safely.

Moreover, it is preferable that the predetermined fixing means is provided with a means for adjusting a fixing position or a fixing angle of the light emitting device .

  Thereby, the convenience can be further improved.

In any one of the configurations described above, it is preferable that a fluorescent material is disposed on the rod-shaped member .
