Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a perspective view showing the best mode for carrying out the invention according to the present application.
A portable information device case (hereinafter simply referred to as a case) 1 shown in FIG. 1 is a protective and decorative case that is detachably attached to the portable information terminal 21 shown in FIG.

The portable information terminal 21 has a rectangular display unit 23 on the front surface 22 a of the terminal body 22. The shape of the terminal body 22 is a flat, substantially rectangular parallelepiped shape having a rounded periphery. A front surface 22 a of the terminal main body 22 is a flat surface, and most of it is an area of the display unit 23. On the other hand, most of the back surface of the terminal main body 22 including the central portion is a flat surface, and a portion outside the flat portion is formed of a smooth curved surface. An operation button 24 is provided at one end of the front surface 22a of the terminal main body 22, and an earpiece 25 is provided at the other end. A connector 26 is provided at the center of the end of the terminal main body 22 on the side where the operation buttons 24 are provided, and microphones 27L and 27R and speakers 28L and 28R are provided on the left and right sides, respectively. Further, a silencer switch 29, a volume key 30, and the like are provided on the side of the terminal body 22.
The portable information terminal 21 can be used as a computer, a media player, a game machine, a media storage device, a personal digital assistant (PDA), or a communication device (for example, a mobile phone, an Internet browsing device, a GPS navigation device). The display unit 23 has a touch screen function, and various operations of the portable information terminal 21 can be performed by touching the display unit 23.

  The case 1 includes a case body 2 that covers at least the back surface of the portable information terminal 21, a ring-shaped support leg 3 having one end connected to the case body 2, and the case body 2 and the support leg 3. A biaxial hinge mechanism 4 that is pivotally coupled around a first axis (A1) parallel to the back surface (flat portion) of the first and second axes (A2) perpendicular to the back surface; ,have.

  The case body 2 includes a portion (hereinafter referred to as a case body rear surface portion) 5 that covers the back surface of the portable information terminal 21 and a portion (hereinafter referred to as a case) that covers and fits the peripheral portion of the portable information terminal 21. (Referred to as the body periphery). The case body peripheral edge portion 6 has cutout portions at various locations so that the case 1 is not interfered with the microphones 27L and 27R, the speakers 28L and 28R, the silencer switch 29, the volume key 30 and the like when the case 1 is attached to the portable information terminal 21 7 is formed (see FIG. 4).

  The biaxial hinge mechanism 4 is provided at a position overlapping the center of gravity of the portable information device 21 on the case body back surface portion 5. The range of relative rotation around the first axis (A1) of the case 1 and the support leg 3 is 90 °, and the rotation angle around the first axis (A1) is 0 ° (a state where the support leg 3 is completely tilted). The posture is autonomously held at 90 ° (a state where the support leg 3 is completely raised). Moreover, the relative rotatable range of both around the second axis (A2) is 360 °, and the posture is autonomously held every 90 °.

  The case body back surface portion 5 is formed with a recess 8 for accommodating the support leg 3 in a tilted state. The depth dimension of the recessed part 8 is selected so that the side surface of the support leg 3 slightly protrudes from the case body back face part 5 in a state where the support leg 3 is accommodated.

  The support leg 3 is selected so that its inner diameter dimension can be loosely fitted to the finger F of the user's hand. The outer periphery of the support leg 3 is provided with a metallic luster decoration 9 by metal plating.

  The case 1 configured as described above has the support leg 3 raised by rotating the support leg 3 around the first axis (A1) with respect to the case body 2 (see FIGS. 1B and 1C). It is possible to change the state to the state shown in FIG. 1 or to the state (shown in FIG. 1A), and by raising the support leg 3, as shown in FIG. 2 and FIG. It can be used as a simple stand for using the portable information terminal 21 while being inclined. With the support leg 3 raised, the installation angle of the portable information terminal 21 can be adjusted by rotating the support leg 3 by 90 ° around the second axis (A2). Since the biaxial hinge mechanism 4 connecting the case body 2 and the support leg 3 is provided at a position overlapping the center of gravity of the portable information device 21 on the case body back surface portion 5, the portable information device can be used when used as a simple stand. 21 can be stably supported by the support leg 3. Further, when not used as a stand, the support leg 3 can be folded down and folded compactly, so that portability is good.

  Further, according to the case 1, the shape of the support leg 3 is a ring shape, and the inner diameter dimension of the support leg 3 is selected so as to be loosely fitted to the finger F of the user's hand. Thus, the portable information terminal 21 can be used with one hand while the finger is passed through the support leg 3. According to this usage mode, the portable information terminal 21 can be used in a state of being connected to the user's hand. Accordingly, it is possible to prevent an accident in which the hand slips unexpectedly and drops the portable information terminal 21 while the portable information terminal 21 is used in a one-handed state. Moreover, since it is not necessary to use much gripping force while the portable information terminal 21 is used in a one-handed state, the fatigue of the user can be reduced. Moreover, since the metallic luster decoration 9 by metal plating is given to the outer peripheral part of the support leg 3, when using the support leg 3 with a finger | toe, the aesthetic appearance which is carrying out a metal ring is exhibited.

  In the above example, the outer periphery of the support leg 3 is decorated with metallic luster by metal plating. However, as illustrated in FIG. 6, a decoration 9 made of crystal glass or jewelry may be applied to the support leg 3. . Moreover, a metal may be used for the material of the support leg 3 itself, and the gloss finish or mat finish may be given to the surface.
