It is said that

An embodiment of the invention is shown in FIGS. 1 to 8. That is, this electric shaver case has a flat box shape consisting of an upper case 1 and a lower case 2, and the peripheral edges of the cases 1 and 2, except for one end 3, are tapered 4 so that they can be stored in a handle or a travel bag, etc. One end 3 is provided with a rib 3b on the periphery of the surface 3a to sink the surface 3a to form a recess, and a push operation part (PUSH) 5 for opening and closing is provided flush with the surface 3a. There is. Further, as shown in FIG. 2, the lower surface of the lower case 2 is formed with a bulging support plate 6, and small hemispherical feet 1 are protruded from the four corners of the support plate 6. In this way, the appearance of the case resembles that of a leather case. The upper case 4 is formed by molding a resin material, and the top plate 8 has a taper 4 in a U-shape when viewed from the top except for the one end 3 side, and at the same time has an inner wall formed on the back surface corresponding to the taper 4. Taper 4' sinking in the direction
is displayed. A cushion plate 9 is attached to the central portion of the back surface of the top plate 8, that is, the portion surrounded by the taper 4'. The lock pawl 10 is extended outward from the central edge of the concave surface 3a' of the one end 3 of the upper case 1, and grooves 11 and 11' are formed inward along both sides of the lock pawl 10. is made to have flexure due to resin elasticity, and a push operation part 5 is formed in the middle part thereof. One end 3 of upper case 1
A hinge plate 13 corresponding to the height of the lower case 2 extends outward from the opposite end 12 facing the lower case 2, and a cylindrical shaft 14 is formed so as to protrude inward at its tip. An opening regulating surface 15 is formed on. The lower case 2 is also molded with resin in the same way as the upper case 1, and a U-shaped taper 4 corresponding to the taper 4 of the lower case 2 is formed inside the bottom plate 16, and the support plate 6 is molded with a U-shaped taper 4 corresponding to the taper 4 of the lower case 2. A corresponding recess 11 is formed in the center surrounded by the taper 4, and a notch 18 into which the push operation part 5 of the upper case 1 enters is formed at one end 3, and the lower part of the notch 18 is formed. A locking recess 19 into which the lock pawl 10 locks is formed inside as shown in FIG.

Further, the opposite end 20 opposite to this one end 3 is the upper case 1.
A recess 21 that is recessed inward of the case to accommodate the hinge plate 13 of the
The edge 23 of the bottom bottom 22 is used as a stopper 23 in an open state (FIG. 7), and the bottom plate 1 is held at both ends of the end 20.

1 and aligned with the insertion hole 25, and is assembled by press-fitting the rotating shaft 26 into the insertion hole 25 and the cylindrical shaft 14,
When the lid is closed, the push operation part 5 fits into the notch 18, and the lock pawl 10 locks into the locking recess 19 with resin elasticity, and when the lid is opened, it rotates around the rotating shaft 26 and engages with the stopper 23. The maximum opening amount is regulated by the collision with the surface 15.

On the other hand, a support base 11 for positioning an electric shaver 27 is attached to a recess 17 in the center of the bottom plate of the lower case 2.

This support base 11 is made of an elastic material such as rubber, and corresponds to the shape of the T-shaped reciprocating electric shaver to be positioned. There is a U-shaped rib 29 for positioning the rear end 21b of the electric razor 27, a mounting rib 31 for the hair removal brush 30 near the rear end on one side, and a power cord 32 (charging AC adapter) on the other side. The positioning ribs 34 of the plugs 33 are integrally formed. The brush mounting lip 31 consists of a box frame part 31a that surrounds and supports one side of the handle part 30a of the brush 30, and a pair of side parts 31b and 31c that hold and prevent the brush from falling down. Further, the plug positioning rib 34 is made up of a pair of side parts 34a and 34b that sandwich the rear side of the main body of the plug 33, and a protrusion 34c that engages with the front end surface 33b, which is the side from which the plug blade 33a protrudes. . FIG. 4 shows the electric shaver 27 in its stored state, with the head 27a attached to the pillow part 2.
8, the rear end portion 27b is placed in the U-shaped rib 29 and positioned, the brush 30 is placed in the brush mounting rib 31 and the power cord 32 is placed in the plug positioning rib 34, and the curled portion 32a is placed in the position. It is positioned in a U-shape by extending it along the letter-shaped taper 4 and having its inner side supported by the outer peripheral surface of the outer side 34b1 of the plug positioning rib 34, the outer peripheral surface of the pillow part 28, and the outer side 31b of the brush mounting rib 31, respectively. be done.

That is, the cord storage portion 35 has a taper of 4//. It is formed by the inner surface of the lower case 2 and the rib group of the support base 11. When the electric shaver 27 etc. is stored and the upper case 1 is closed, the electric shaver 27 is closed by the cushion plate 9 of the upper case 1.
Press and fix.

Further, as shown in FIG. 6, a U-shaped rib 29 is located behind the lock pawl 10 that is locked in the locking recess 19, so that it serves as a support to prevent damage when excessive external force is applied to the push operation part 5. . Because of this structure, this electric shaver case has the following features.

That is, (1) the electric shaver 27 is located in the center of the lower case 2, the cord 32 is stored around it in a U-shape, and the cord 32 is placed in the lower part of the upper case 1 corresponding to the U-shaped portion of the cord storage section 35; Since each side of case 2 is formed into a tapered shape, cases 1 and 2 can be opened by closing both cases 1 and 2.
The volume of the cord storage part 35 can be reduced, unnecessary wobbling of the cord 32 can be prevented, and the entire case can be downsized. Note that the taper 4' of the upper case 1 may be omitted.
1, an electric shaver 21 is placed here, and ribs 28, 29, 31,
34, a space is provided between the lips 28, 29, 31, 34 and the inner surface of the case, either in the entire area or in the corner (for example, in a U-shape), and the cord 32 is placed in this space. A cord storage portion 35 is formed between the ribs 11 and the inner surface of the case, so that a cord-dedicated holding member is not required and the case structure is simplified.

(3) If the rib 29 of the support base 11 is located behind the lock pawl 10 located on the lower case 2 when the lid is closed and the push operation part 5 for unlocking is pushed in more than necessary, the lock pawl 10 will be removed from the rib. 29, it is possible to prevent the lock pawl 10 from being damaged due to unnecessary pushing of the push operation section 5 and external force impact.

(4) It also serves as a holding rib for the cleaning brush mounting rib 31.

Since the outer side part 31b also served as the positioning of the cord 32,
The support stand 11 functions to position the cord 32 and hold the brush.
Can be used for both purposes, reducing the number of ribs. (5) As shown in Fig. 8a, the hinge rotation shafts 26 of the upper case 1 and lower case 2 are located at the lower part of the side wall of the lower case 2, which is different from when they are located at the upper part as shown in Fig. 8b. In comparison, when the case is opened, the center of gravity of the upper case 1 is located at the bottom, which increases stability.
The entire case rarely falls forward.

(6) Since the rotating shaft 26 is inserted from the side surface of the lower case 2 and supported by a hinge, assembly is easy and the holding strength is high. (7) As shown in Fig. 8c, the taper 4 is provided at the bottom of the lower case 2 on the hinge side, so compared to the case where the taper 4 is formed as shown in Fig. 8d, when the case is opened, the entire The primary inclination angle α1, α2 when
Since α1 < α2, it is easy to return (P is the grounding point).

(8) Since a taper 4 is formed on the outer periphery of the cases 1 and 2, and only one end 3 is flat and the push operation part 5 is provided as a recess, the rib 3b makes it easy to put your finger on it, and only the operation part 5 is flat. The design is simple and easy to use, both in appearance and feel, and the operation section is easy to understand.

Further, even if the case is put into a bag or the like, external force is not easily applied to the operation part 5, so that it can be prevented from being opened unexpectedly. As described above, in the electrical appliance case of the present invention, since the cord storage part is formed between the rib for positioning the electrical appliance and the inner peripheral surface of the case body, it is not necessary to separately configure a cord supporting member. This has the advantage that the case structure can be simplified while ensuring the positioning of instruments, and can be made smaller and cheaper.
