[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the rotary handle of the beauty device of the present invention will be described below with reference to the drawings. This rotating handle is configured such that a handle 4 connected to a vertical portion 2 of a main housing 1 constituting a beauty tool such as a hair dryer 6 as shown in a simplified form in FIG. 10 can be rotated 180° from either the left or right direction by a rotating hinge structure 3 as shown in FIG. 9 and can be freely folded. This is preferably applied to a thermal beauty device in which the main housing 1 is formed into a rod shape, and below, an example in which it is applied to a hair dryer 6 will be described, but it can also be implemented in beauty devices such as hair irons and hair brushes, whose descriptions are omitted, as well as electric skin care beauty devices and electric massage beauty devices.

[0020] <First Example> The outline of the rotary handle of the beauty device according to this embodiment is that the handle 4 is rotatably connected to the vertical part 2 of the rod-shaped main body housing 1 which constitutes the core of a general hair dryer 6 (FIG. 10). The rotary hinge structure 3 provided on the connection surfaces 20, 40 of the vertical part 2 and the handle 4 is composed of a first hinge component 3A fixed to the vertical part 2 and a second hinge component 3B rotatably fixed to the handle 4 (FIG. 2). The second hinge component 3B is provided with a shaft part 35 with a rotation transmitting part 36, while the first hinge component 3A is provided with an insertion hole 31 through which the shaft part 35 is inserted, and a rotation transmitting stopper 33 which can move within a predetermined range by the rotation transmitting part 36 coming into contact with the outer periphery of the insertion hole 31 is provided, and the handle 4 is configured to be rotatable to a predetermined position in either the left or right direction S or R (FIGS. 1 to 9).

[0021] The inside of the second hinge construct 3B including the shaft portion is formed as a hollow portion 36 that penetrates the middle, and a conductor 50 that connects the base 41 on the handle 4 side and the base 21 on the vertical portion 2 side is inserted into the hollow portion 38 of the second hinge construct 3B (FIG. 7). When this wiring conductor 50 is inserted into the second hinge construct 3B, if the handle 4 rotates 180° or more (up to 360°) in either the left or right direction S, R, there is a risk that the conductor 50 will be twisted, so it is preferable to set it so that it will rotate up to 180°.

[0022] The handle 4 of this hair dryer 6 is formed in a cylindrical shape with respect to the cylindrical vertical part 2 that protrudes vertically and is fixed to the rod-shaped main body housing 1. The handle 4 and the vertical part 2 are each formed by joining two halves (see FIG. 11). The connection surfaces 20, 40 of the vertical part 2 and the handle 4 are formed on inclined surfaces cut at an angle of 45° in the axial direction K (see FIG. 1, FIG. 2, FIG. 7, FIG. 11). Therefore, as shown in FIG. 9, the handle 4 can be rotated by 180° in the left direction S diagonally and can also be rotated by 180° in the right direction R diagonally, and when the handle 4 is rotated 180° and folded, the main body housing 1 and the handle 4 are arranged in parallel (FIG. 10C). When the vertical portion 2 is embodied in a cylindrical shape, the handle 4 is also preferably embodied in a cylindrical shape of the same shape.

[0023] The rotary hinge structure 3 shown in Figs. 1 to 7 and Figs. 11 to 15 will be described. The rotating hinge structure 3 shown enlarged in Figures 4A, 14 and 15 is composed of a first hinge component 3A fixed to the vertical portion 2 side of the main housing 1, and a second hinge component 3B fixed to the handle 4 side so as to be freely rotatable, and is provided on the inclined surface 20 of the vertical portion 2 and 40 of the handle 4 (see Figure 11).

[0024] 1, which shows the second hinge structure 3B of the rotary hinge structure 3, is a combination of a rotary plate 30b, which has a rotary cylindrical shaft 35 at its center from which a convex rotation transmission part 36 protrudes obliquely upward, and two cylindrical parts 30b' for receiving two bullet-shaped convex parts 37, which are provided at 180° opposite positions below the rotary cylindrical shaft 35, and a base plate 30a to which the convex parts 37 are biased by a spring as an elastic member 39 and fixed with a screw. A through hole 30a' through which the wiring conductor 50 is inserted is drilled in the center of the base plate 30a (see FIG. 7). This second hinge structure 3B is fixed to the opening center part 41 of the inclined flat connection surface 40 of the handle 4. The first hinge component 3A is provided with a fixed plate 30c having a through hole 31 in the center through which the rotating cylindrical shaft portion 35 is inserted, and two recesses 32 in which the bullet-shaped protrusions 37 are fitted, which are provided at positions 180° opposite each other across the central through hole 31, and a rotation-transmitted stopper 33 is provided on the upper surface of the recesses. An upper block 34' having a curved groove portion 34 is fixed to the upper surface of the fixed plate 30c, and the rotation-transmitted stopper 33 is configured to be movable within a range in which both ends 33a of the curved groove portion 34 are abutted against it and the movement is restricted (see FIG. 12). The first hinge component 3A having the above configuration is fixed and attached to the opening center portion 21 of the inclined flat connection surface 20 of the vertical portion 2 of the main body housing 1.

[0025] Therefore, when the handle 4 is rotated to the left S or right R, the rotation transmitting part 36 comes into contact with the rotation transmitted stopper 33 and moves, and then the bullet-shaped convex part 37 biased by the elastic member 39 fits into the concave part 32, stopping the handle 4 at a rotation angle of 180°, and further rotation of the handle 4 in the same direction is restricted. At that time, the loaded elastic member 39 smoothly controls the movement of the rotation transmitted stopper 33, which comes into contact with and moves with the rotation transmitting part 36 of the second hinge construct 3B.

[0026] A plastic rotating cylindrical shaft portion 35 having a protruding rotation transmission portion 36 provided on the outer periphery is provided approximately at the center of the second hinge component 3B. On the other hand, the first hinge component 3A is provided with an insertion hole 31 through which the rotating cylindrical shaft portion 35 is inserted. The rotation transmitting portion 36 abuts against the end portion 33a of the rotation transmitting stopper 33, and the handle 4 is positioned to stop at an angle of 180° to either the left or right. A curved groove portion 34 that restricts the movement of the rotation transmitting stopper 33 is formed in the first hinge component 3A of the rotating hinge structure 3. A rotation-transmitted stopper 33 movable within a predetermined range is provided near the outer periphery of the insertion hole 31 of the first hinge component 3A. This rotation-transmitted stopper 33 is made of metal, plastic, or rubber resin. By changing the size, shape and movable range of the rotation transmitted stopper 33, the rotation angle of the handle 4, which will be described later, can be changed.

[0027] More specifically, the upper block 34' having the curved groove 34 as shown in Fig. 12 is fixed to the upper surface of the fixed plate 30c at the outer periphery of the rotating cylindrical shaft 35 inserted into the through hole 31 as shown in Fig. 4A and Fig. 1. The curved groove 34 is formed along the outer periphery of the rotating cylindrical shaft 35 so as to have an opening angle of about 120° with the rotating cylindrical shaft 35 as the center. The rotation-transmitting stopper 33 inside the curved groove portion 34 is set to be movable within the curved groove portion 34 at a position facing the convex rotation-transmitting portion 36 across the rotating cylindrical shaft portion 35.

[0028] Therefore, by rotating the handle 4, which is arranged in a straight line relative to the vertical part 2 as shown in Fig. 10A, in the left direction S, the convex rotation transmitting part 36 of the rotating cylindrical shaft part 30 comes into contact with one end part 33a of the rotation transmitted stopper 33, and the other end part 33a of the rotation transmitted stopper 33, which has been pushed forward, is stopped at the end position of the curved groove part 34 (Fig. 6B). At this time, the rotated handle 4 traces a trajectory (symbols A→B→C→D→E in Fig. 9) as shown on the left side of Fig. 9, and is folded and stopped at a position rotated 180° left (see Fig. 10). Similarly, when the handle 4, which is arranged in a straight line relative to the vertical part 2 as shown in Fig. 10A, is rotated in the right direction R, the convex rotation transmitting part 36 of the rotating cylindrical shaft part 30 comes into contact with one end part 33a of the rotation transmitted stopper 33, and the other end part 33a of the rotation transmitted stopper 33, which has been pushed forward, is stopped at the end position of the curved groove part 34 (Fig. 6A). At this time, the rotated handle 4 traces a trajectory (symbols A → F → E in Fig. 9) as shown partially in the right side of Fig. 9, and is folded and stopped at a position rotated 180° to the right (see Fig. 10). Thus, the handle 4 can be rotated from the top dead center to the bottom dead center due to the interference of the movable rotation transmission stopper 33 which is located at an opposing position of 180° to the convex rotation transmission part 36 of the rotating cylindrical shaft part 35, and is configured to be folded up to a predetermined position while rotating diagonally in either the left or right direction S, R with respect to the axial direction K of the main housing 1.

[0029] <Second Example> In this embodiment shown in Fig. 16, the second hinge component 3B of the rotary hinge structure 3 of the first embodiment described above is fixed to the vertical portion 2' of the main body housing 1, and the first hinge component 3A is rotatably fixed to the handle 4', and similar to the first embodiment described above, the handle 4 can be rotated and folded in either the left or right direction. That is, this embodiment can also be preferably implemented by attaching the second hinge component 3B described above to the central opening 21' of the inclined connection surface 20' of the vertical portion 2' as shown in Fig. 16, and attaching the first hinge component 3A to the central opening 41' of the inclined connection surface 40' of the handle 4', and the handle 4' can be rotated and folded freely in either the left or right direction. Of course, the wiring conductor 50 can be inserted into the hollow portion 38 of the second hinge structure fixed to the vertical portion 2, thereby improving the reliability of rotation. The configurations of the first hinge component 3A and the second hinge component 3B are similar to those of the first embodiment described above, and therefore a description thereof will be omitted.

[0030] Although the embodiments have been described above based on the drawings, it should be noted that the present invention is not limited to the illustrated examples, and includes the range of design modifications and application variations that would normally be made by a person skilled in the art, provided that the scope does not deviate from the technical concept of the present invention.
