Description

[Detailed Description of the Invention] The present invention relates to an improvement in a storage case that can store and carry corded electrical components such as earphones and small microphones when not in use.

Traditionally, when corded earphones and small microphones are stored when not in use, the cords are folded and bundled or wrapped around a reel. and is not protected from external forces. In addition, some methods have been used to store the cords in bags or cases, but it is troublesome to gather the cords together when storing them, and the cords are easily damaged due to wrinkles or tangles. . Furthermore, cases have been considered in which the cord is wound up and stored, but the cord must be folded in half and tied, or the earphones and plug must be placed in the storage area after being wound up, and the above-mentioned drawbacks have not been solved. It's not.

The present invention aims to eliminate the above-mentioned drawbacks and provide a storage case that is easy to store and convenient to carry. The gist of the present invention is that a storage recess for storing electrical components is formed in the inner circumference, a winding part for winding up the cord of the electrical component is formed in the outer peripheral part, and the winding part is stored in the storage recess. a lower case to which a first rotating body is rotatably attached, the first rotating body having a notch for leading out the cord of the electrical component to the winding part; An engaged portion that engages with the provided engaging portion is provided, and the one surface is formed so as to close the storage recess in a state where the engaging portion and the engaged portion are engaged, an upper case in which a second rotating body having a rotational operation part formed on the other surface is rotatably attached so that the operation part can be directly rotated from the outside, and is provided to be openable and closable with respect to the lower case; By closing the upper case with respect to the lower case, the engaging portion and the engaged portion engage with each other, and as the second rotating body rotates, the second rotating body and the second rotating body engage with each other. The electrical component storage case has a cord, in which one rotating body rotates as a unit, and at least the lower case is provided with a plug intake opening for a plug provided in the cord of the electrical component stored in the storage recess. The present invention will be specifically explained below with reference to the illustrated embodiments.

FIG. 1 is a perspective view showing a preferred embodiment of the present invention. In the figure, 1 is a substantially square upper case, and 2 is a lower case of the same shape.Although not shown, the upper and lower cases 1 and 2 are connected so as to be openable and closable by a suitable means such as a hinge. 3 is a rotating plate attached to the upper case 1 so as to be rotatable from the outside, and 4 is a rotating plate attached to the lower case 2 in correspondence with the rotating plate 3. 5 indicates earphones, and 6 indicates a cord. The cord 6 is attached to the rotary plate 4.
A winding frame 4 ₁ is provided for winding up the cord 6. A part of the winding frame 4 ₁ has a notch 4 ₄ through which the cord 6 is passed, and an engagement uneven portion 4 ₂ is provided on the upper surface of the frame 4 ₁ . is formed. The rotating plate 3 is also provided with an uneven portion 3 ₁ that corresponds to and engages with the uneven portion 4 ₂ of the winding frame 4 ₁ . Furthermore, cutouts 1 ₁ and 2 ₃ are provided at the corners of the upper case 1 and the lower case 2, respectively, for receiving the plugs.

FIG. 2 is a sectional view taken approximately along the center line of FIG. In the figure, parts corresponding to those in FIG. 1 are given the same reference numerals. A concave groove is formed on the outer periphery of the rotating plate 3, and an opening with a protruding strip formed on the inner periphery is provided in the upper case 1, and the rotating plate 3 is loosely fitted into the opening. As a result, the rotating plate 3 is connected to the upper case 1.
It is supported and rotatable. A bearing portion 4 ₃ is formed at the center of the rotating plate 4 and loosely fitted into a holed shaft boss 2 ₁ provided at the center of the lower case 2 .
As a result, the rotating plate 4 is supported by the lower case 2 and is freely rotatable about the shaft boss ₂₁ . A pin 3 ₂ is provided at the center of the rotary plate 3, and when the upper case 1 and lower case 2 are closed, the pin 3 ₂ fits into the hole 2 ₂ of the holed shaft boss 2 ₁ of the lower case 2. At this time, the uneven portion 3 ₁ of the rotating plate 3 engages with the uneven portion 4 ₂ of the rotating plate 4. Note that 3 ₃ is a recessed portion for making it easier to rotate the rotary plate 3 with fingers.

Next, how to use this embodiment will be described. First, electrical components such as earphones 5 or a small microphone are stored in the space inside the winding frame 4 ₁ of the rotary plate 4, and the cord 6 is passed through the notch 4 ₄ provided in a part of the winding frame 4 ₁ . Notch 2 provided at the corner of the lower case 2 ₃
Pull cord 6 out through the cord. Therefore, when the upper case 1 is closed, the uneven portion 3 ₁ of the rotating plate 3 and the uneven portion 4 ₂ of the rotating plate 4 engage with each other as described above.
In this state, as shown in _{FIG .}
rotates, and the cord 6 is wound onto the winding frame ₄₁ ,
It is stored in the space between the winding frame ₄₁ and the side wall of the storage case.

In this embodiment, notches 1 1 and 2 ₃ corresponding to each other are provided at the corners of the upper case 1 and the lower case ₂ , respectively.
are provided, upper case 1 and lower case 2.
When the case is closed, a fairly large opening 7 is formed at the corner of the case. Therefore, as shown in FIG. 4, even a fairly large plug 8 can be easily accommodated. In this case, by providing the notches 1 ₁ and 2 ₃ at the corners of the case, it becomes possible to take in the plug 8 with a relatively small notch. Further, depending on the case, it may be sufficient to provide the notch only in the lower case.

As is clear from the above description, according to the present invention, the main body of the corded electrical device is stored in the winding frame, and the upper case is placed over the lower case,
By simply turning the rotating plate from the outside with your fingers, not only is the cord easily wound up, but the plug terminal connected to the tip of the cord is also easily stored, so compared to conventional devices, there is no need to store the electrical components and plugs one by one after winding the cord, making storage extremely easy. Moreover, since the plug closes the opening after storage, the electrical component body is not exposed to dust or iron powder and is protected from external forces. Furthermore, even if the electrical component body abuts against the inner surface of the rotating plate 3 of the upper case 1, the rotating operation part is naturally not overloaded or damaged by overload, allowing smooth operation, no abnormal noise is generated, and the electrical component body or the inner surface of the rotating plate 3 are not damaged. Furthermore, since the electrical component itself acts as a retainer, there is no need to make a knot on the cord, and breakage and damage to the cord can be prevented. Furthermore, the cord does not get wrinkled, and there is no need to fold the cord in half and tie it, so the cord is not damaged. Furthermore, the thickness of the case can be made relatively thin when the upper case is closed, making it convenient to carry in a pocket or the like. Furthermore, if the electric components are first stored and the upper case is then closed, the winding work is then completed, making the work extremely simple.

The present invention is not limited to the above-mentioned embodiments, and can be modified and changed in various ways without departing from the gist described in the claims for utility model registration. For example, the shapes of the upper and lower cases do not necessarily have to be square, and the upper case may be in the form of a lid. The rotary plates 3 and 4 may be engaged by gear fitting or clutch fitting (using sliding resistance). There may be one or more cord cutouts ₄₄ in the winding frame ₄₁ , and the cutouts in the case are not necessarily provided at the corners if the case shape is close to a circle. Furthermore, various methods can be considered for attaching the rotating plates 3 and 4.
