Description

[Detailed description of the invention]

[Industrial Application Fields] The present invention relates to clothing with an electrical circuit formed thereon, such as a shirt, jacket, pants, hat, etc., to perform a predetermined electrical function, such as a radio receiving circuit. Regarding. It is something that [Background of the Invention] For example, electrical devices such as radios and wireless receivers are usually used as independent devices, and electrical devices such as clock radios that form part of multifunctional devices are also known. However, even in such a multifunctional device, the electric circuits constituting the electric equipment are provided on an independent board and incorporated into the housing. However, a device in which the material itself of a member having other functions is used as a substrate in an electric circuit has not yet been developed.

[Objective of the Invention 1] The present invention has been made in view of the above points, and its purpose is to use cloth, which is a material for clothing, as a circuit board and to form an electric circuit thereon. According to
To provide clothing with an electric circuit that has the function of an electrical device that exhibits a predetermined electrical function without impairing the original function of the clothing. [Means for achieving the object] In order to achieve the above object, the present invention provides a shirt. A wiring pattern is formed by fixing a conductive member to the front or back side of clothing such as a jacket, pants, hat, etc., and a circuit component member that forms an electric circuit for performing a predetermined electrical function is attached. The present invention is characterized in that the wiring and at least the connection portion between the wiring and the circuit component member are waterproof protected by a resin protective film. [Function] With this configuration, it becomes possible to provide an electric circuit directly to the fabric as a material for clothing. Therefore, for example, if a wireless receiver circuit is formed directly on clothing that is always worn during work, such as the uniform or hat of a person who performs special work that requires carrying a wireless device,
This makes it possible to prevent such devices from being left unattended due to carelessness or the like. Further, similar electric circuits can also be formed in clothing worn by people in occupations such as nurses who need to receive emergency calls at all times. Particularly in recent years, fashion has become more diversified, and various things have come to be used as patterns on clothing. Therefore, an electric circuit can be formed on the surface of a shirt, jacket, etc., either as it is or with some design. For example, if a radio receiving circuit is formed on the surface of a shirt or the like in a state where it can actually be received, radio reception becomes possible, and the shirt becomes fashionably novel and has a unique design aesthetic. Recently, the parts that make up electric circuits have become smaller, lighter, and more highly integrated, and circuit components such as wiring and capacitors can be easily formed by printing and other means. This has made it easier to attach to clothing,
Moreover, various electric circuits can be formed with a relatively simple configuration. Therefore, if the function as an electrical device is important, the circuit configuration may be miniaturized, and if fashion is important, the circuit configuration may be designed. Since it is used as clothing, it must be washed with the electric circuit attached, so at least the wiring and the contact points between the wiring and the circuit components must be completely liquid-tight. Must be retained. However,
Since the parts that need to be kept liquid-tight are protected by a resin protective film, sufficient washing fastness is exhibited, and even after repeated washing, the electrical circuit will not break down and will remain durable. improves. [Example J] Hereinafter, an example of the present invention will be described in detail based on the drawings. First, FIG. 1 shows a shirt in which an AM radio receiving circuit is formed, and FIG. 2 shows an equivalent circuit of this radio. In the figure, ■ indicates an antenna section, Z and 3 indicate a capacitor, and 4 indicates a coil. Radio waves received by the antenna 1 are amplified by a high frequency amplification section 5 and a low frequency amplification section 6, and then transmitted to the earphone 7. , it is possible to receive a single voice of a predetermined frequency. A button battery 8 is attached to supply power to this radio circuit. Furthermore, predetermined wiring 9 including a ground line is routed between each of these circuit components 1 to 8. Here, the AM radio reception circuit configured as described above uses the shirt 10 as a circuit board and is formed directly on the surface of the shirt 10. Therefore, this shirt 10 is made of H&fiber fabric with good electrical insulation properties. Therefore, the configurations of the circuit components 1 to 8 and the wiring 9 formed on the surface of the shirt body 10 are shown below. First, among the circuit components 1 to 8, capacitors 2 and 3 have a configuration as shown in FIG. That is, shirt 1
A waterproof protective layer 11 is provided on the surface of 0, and a conductive layer 12 is formed on this waterproof protective layer 11 by applying a conductive paint such as silver paste. A dielectric layer 13 is laminated on the dielectric layer 13 by applying a dielectric paint made of titanium oxide paste or the like, and a conductive layer 14 is laminated on the dielectric layer 13. Terminals 12a and 14a are drawn out from one conductive layer 12 and the other conductive layer l4, respectively, and these terminals 12a and 14a are connected to wiring 9. moreover,
This uppermost conductive layer 14 is covered with a waterproof protective layer 15, and as a result, the conductive layer 12, dielectric layer 13, and conductive layer 1 are covered with a waterproof protective layer 15.
4 is completely sealed between the waterproof protective layer 11, Is. Here, waterproof protective film 11. 1
Item 5 must not only be made of a material with good electrical insulation properties, but also have excellent moisture resistance, sufficient fastness to washing, and good flexibility. Although silicone resin is most convenient for this purpose, it goes without saying that other types of resins can also be used as long as they have the properties described above. Next, the antenna section 1, coil 4, and wiring 9 are configured as shown in FIG. That is, these antenna parts 1,
A waterproof protective film 20 made of silicone resin or the like is formed on the coil 4 and the wiring 9 as described above, and a conductive paint is applied on this waterproof protective film 20 to form the conductive wire portion 2.
1 is formed, and this conducting wire portion 2l is covered with a waterproof protective film 22. Alternatively, as shown in FIG. 5, the antenna 1, coil 4, and wiring 9 can be connected by using a cable 23 whose core wire is inserted into a resin tube and sewing this cable 23 with thread 24. It can be formed. When the cable 23 is used in this manner, it is not necessary to provide a waterproof protective film as described above since the cable 23 is itself waterproof. In addition, as shown in FIG. 1 as A section, B section, and C section, at the intersections of the wiring 9,
Although it is necessary to interpose an insulating layer between the upper and lower wiring lines to maintain insulation between them, as is clear from FIG. 22, and the cable 23 as shown in FIG.
When using 9, 9 and 9, it is not necessary to interpose an insulating layer between the upper and lower wiring lines 9 and 9, as there will be no electrical short circuit even if they are overlapped, but if necessary, An insulating layer may be interposed between the two. On the other hand, both the high frequency amplification section 5 and the low frequency amplification section 6 are constructed of IC circuit components, and as shown in FIG.
The main body portion 30a is fixed to the surface of the shirt 10 by adhesive or other means, and the lead portion 30b is extended along the surface of the shirt IO. A waterproof protective film 31 is previously formed on the surface of the shirt 10 at the position where the lead portion 30b is installed. In this state, a conductive adhesive 32 is applied between the tip portion of the lead portion 30b and the end portion of the wiring 9, and a waterproof protective film 33 is laminated on this connection portion. As a result, as is clear from FIG. 7, a terminal connection portion can be formed. Furthermore, the button battery 8 is detachably attached to the shirt 10. For this purpose, as shown in FIG. 8, hooks 40a and 40b connect button battery 8 and wiring 9.
It is used as a point of contact between That is, the terminals 8a and 8b of the button battery 8 are connected to the hooks 40a and 8b, respectively.
40b is connected to the male side member, and the female side member is connected to the wiring 9. Therefore, these hooks 40a, 40
By engaging and disengaging b, the button battery 8 can be attached to and detached from the shirt 10. In addition, these hooks 40a, 40
When both hooks b are attached, the radio or the radio will be ON, and when at least one of them is detached, it will be OFF, so these hooks 4ro a and 40b are the radio's O.
It also serves as a switch for performing N and OFF operations. Further, the earphone 7 is also connected to the wiring 9 in the same manner as the button battery 8. This embodiment is constructed as described above, and an AM radio receiving circuit is formed on the shirt 10, so that the original function of clothing and the radio as an electric device are integrated. You will be able to form things. Therefore, by wearing this shirt and connecting the button battery 8 and earphone 7 to the circuit, the user can receive radio waves. The antenna section 1, coil 4, and other wiring 9 are formed in a designed manner, and the waterproof protective film 22 covering the conductor section 21 or the covering tube of the cable 23 is colored in a desired color. Furthermore, by coloring the waterproof protective film 15 that forms the outer skin layer of the capacitors 2 and 3 in a desired color, the entire circuit can be used as a design without impairing its function as a radio. It becomes a debt. Moreover, even if the electric circuit described above is not specially designed, the circuit itself constitutes a novel pattern on clothing. Here, when forming an electric circuit directly on clothing such as a shirt 10, the issues are waterproofness when worn in the rain, waterproofness during washing, and washing fastness. However, among the components that make up this electrical circuit, the conductive and dielectric parts are not exposed to the outside and are protected by a waterproof protective film, so even if you wear them in the rain or wash them repeatedly, Even if the radio is used under harsh conditions such as heavy rain, the parts that make up the circuit will not be damaged and the radio will maintain its durability. Here, is it preferable to prevent the earphones 7 and the button battery 8 from being immersed in washing water during washing? 40b, these members can be removed when washing. In the embodiments described above, earphones may be used or, for example, a thin plate-like speaker may be attached. The speaker may be detachably attached using, for example, a hook-and-loop fastener. In addition, in order to enable volume adjustment and tuning, electrical parts such as variable resistors and variable capacitors may be attached.2 These variable parts may be formed using fasteners as accessories for clothing. It is also possible. Furthermore, in addition to radios, circuits constituting various electrical devices, such as light-emitting circuits for light-emitting diodes, can also be formed on clothing. It is sufficient that a circuit having a predetermined electrical function is formed on the top of the garment, and the circuit may be formed on jackets, pants, hats, etc. in addition to shirts. For example, if a radio receiving circuit is installed in the hat worn by nurses, they will be able to receive emergency calls at all times, and nurses will also be able to perform special tasks that require carrying a radio. If a direct wireless receiving circuit is formed on clothing that is always worn during work, such as a worker's uniform or hat, it can be used for various purposes, such as preventing devices from being left unattended due to carelessness. It comes to have. [Effects of the Invention 1] As explained above, the present invention uses the front or back side of clothing as a substrate for an electric circuit, and forms a wiring pattern by fixing a conductive member thereto, and also performs a predetermined electrical function. It is equipped with a circuit component that forms an electric circuit for performance, and the above-mentioned wiring and at least the connection between this wiring and the circuit component are waterproof and protected by a resin protective film, so it can be used as clothing. This clothing can be made to function as a predetermined electrical device without impairing its original function.
