Description

[Detailed description of the device]

[0001]

[Industrial applications]

 As a power source for various devices that use electric appliances in various constructions or leisure activities, it can be used to supply a large amount of power, and can be wrapped around the waist of the human body or hung on the shoulder (hereinafter referred to as wearing on the human body as a whole. ) The power source for portable use.

[0002]

[Prior art]

 In conventional power tools or playground equipment, portable lighting equipment, etc., the battery that serves as the power source for them can easily obtain the desired large power by converting from the commercial power source in the case of fixed equipment. However, most of the equipment used while moving is supplied from the battery, and if it cannot be supplied from the car battery, use a large and heavy secondary battery. They had to either endure the inconvenience or use disposable AA-AA batteries with a short life. Furthermore, as a power source for tools that require a large amount of power, such as large-diameter holes and sanders for grinding, practical work tools cannot be expected to be used continuously. In addition, for camping lights and electric scooters for cashiers, it is impossible to use them for a long period of time. It is not practical because it imposes a burden on the behavior and causes natural overload.

[0003]

[Issues to be solved by the device]

 Since conventional battery-powered tools do not have a small-sized and appropriate large-capacity battery, it is very inconvenient to operate for a long time if the large battery part is carried separately and carried by hand. There was the inconvenience of having to always carry dry batteries or otherwise keep a spare secondary battery charged. Furthermore, when working in high places, it has become an unreasonable struggle to get down to the ground to replace a battery with a small electric capacity each time the power is cut off, or to lift and replace a spare battery.

Further, in working behaviors using electric equipment, the electric power cord is often caught in the work even with an electric drill or an electric sander, so that the power cord is caught in an obstacle and the electric equipment is removed to cause an injury. It may damage nearby equipment, and when suspending work with an electric power tool, there is no place to put the power tool, especially when working in high places, so it must be placed in an unstable position. There were many cases of unexpected disasters and unexpected situations. In addition, the large-capacity batteries currently on the market are heavy and large in blocks, and of course, whether they are for work or leisure, they are poor in operability when handheld, and in a block form, the body is balanced. I feel bad and tired. Therefore, as a power source, a recently developed compact secondary battery with large electric capacity is used, and it is effective for long-term electric work in places where commercial power cannot be obtained or for operating various equipment with large electric capacity. A battery pack is provided.

[0005]

[Means for Solving the Problems]

 Therefore, just as electric workers would hang tools on a belt wrapped around their waists, they installed 20 large 1.2-volt batteries that were recently commercialized and attached them to a part of the belt. These switches can be combined in series or in parallel with a changeover switch so that two types of electric power of 12 volt and 24 volt can be taken out according to the application, so that they can be used by connecting them to electric devices by plugging them. We have devised a belt-type battery pack that can be connected to a charger with the.

[0006]

[Action]

 The belt-type battery pack (12), which was devised and prototyped this time, has 20 rechargeable batteries, 10 of which are connected in series, and 12 V or 24 of which can be connected in series or in parallel by connecting them in series or in parallel. A belt-type battery with an expansion and contraction adjustment tool (6) that can adjust the electrical related parts made into a circuit structure that can be taken out as a bolt to an appropriate length for mounting on the human body, and a buckle (5) that can be easily attached and detached. Careless due to the power cord (11) and its plug (4) connecting between the pack (12) and the equipment that uses this power source, and also because this power cord (11) crosses the space during work. Keep the power cord (11) along your body as much as possible so as not to get caught in foreign matter and damage electric equipment or damage other equipment. Power cord (11) Sabuberuto for free prevention (13), the hook for working instrument al (14) is provided.

[0007]

【Example】

 An embodiment of this invention will be described with reference to the embodiment. Ten small and large-capacity secondary batteries (1) connected in series at 12 volts are used as one unit, and two units are used. These two units can be further connected by a switch (2) as desired. Connect the plug (4) connected to the external device (3) through the switch (2) in series or in parallel to the belt (7) to which the buckle (5) and the expansion adjustment tool (6) are attached. In order to make the secondary battery (1) fit to the belt (7) and the body shape more easily when it is worn on the human body, the secondary battery (1) is attached to the belt (7) by the partition wall (8). A cover (10) for holding and protecting each exposed battery electrode (9) is entirely covered and protected. This cover (10) needs to protect the whole of the secondary battery (1), the partition (8), the belt (7) and the like, and is made longer than the entire length of the continuous partition in order to fit the body shape of the user. Both ends are fixed to the belt (7).

A battery pack (12) having such a structure is attached to a human body, and a plug (4) for connecting to an external device (3) is provided at a tip of a power cord (11) coming out of the battery pack (12). Is attached to connect to the external device (3). Furthermore, since the battery used is a secondary battery, it can be charged from the plug (4) at the tip of the power cord (11) for supplying power from the battery pack (12) to the external device (3). it can. Also, in order not to loosen the power cord (11), put the arm through the plurality of sub-belts (13) in the middle of the power cord (11) to prevent foreign matter from being caught on the power cord (11). In addition, the hook (14) is provided as a practical indispensable element by temporarily hooking a small electric tool that is difficult to place in high places. The material of the sub-belt (13) is a cord or rubber cord, but other than this, a surface fastener may be adopted.

[0009]

[Effect of device]

 Since conventional battery-powered tools have a limited electric capacity, it is inconvenient to constantly charge the spare battery and replace the battery many times. In addition, when working in high places, it was always difficult to get down to the ground to replace the battery every time it ran out, and to lift the spare battery for replacement. In addition, recently, the development of leisure equipment has become brisk, and the need for mobile power sources has increased, and the effect of the battery pack of the present invention is extremely large. Since this battery pack can easily switch between various voltages, the effect that it can be commonly used for various devices is great. In addition, in the conventional electric appliances for work, no consideration has been given to many accidents due to the power cord used in the suspended state. The sub-belt provided in the middle of the power cord prevents the power cord from being distant from the body and prevents accidents caused by hanging the power cord in advance. If you have a problem, you can hang the hook on the belt of the belt-type battery pack of the present invention to temporarily hold it safely, and it can also be used as a hook for a storage bag for small parts. The wide range of effects has been fully demonstrated in the test of prototypes.
