Description

[[TECHNICAL FIELD]]

[0001] The present invention relates to an accessory for a portable electronic device that is provided with a ring for hooking a finger so as to be easy to hold when using a portable electronic device such as a mobile phone or a tablet PC (hereinafter also referred to as a "portable device"). [[BACKGROUND ART]]

[0002] Various types of accessories have been developed that allow a user to easily hold a portable device such as a mobile phone when the user uses the same. As one such accessory, there is an accessory in which a ring-shaped finger hook is provided on the back surface of a portable device. This conventional smartphone ring is rotatably provided on a support portion provided on the accessory main body, but cannot be detached from the accessory main body.

[0003] Patent Document 1 discloses, as an accessory for a portable electronic device that enables a portable electronic device such as a mobile phone to be easily carried or placed, an accessory fixed to a partial region at approximately the center of the back surface of the portable device. This accessory includes a base that has an entrance / exit at one end and a moving path formed on the top surface, a guider disposed inside the base, and a cover for accommodating the guider in the base. Then, a ring-shaped handle is rotatably attached to an upper moving piece, and a connection block having a polygonal swing plate at a lower portion thereof has the swing plate portion inserted into the base, so that the moving piece can move within the moving path. The guider is provided with a plurality of pairs of fastening grooves arranged in the moving direction of the moving piece on two opposing sides of the guider, and the polygonal swing plate is rotatably and temporarily locked in the fastening grooves. This accessory allows the ring-shaped handle portion to be detached from the base, [[PRIOR ART DOCUMENT]] [[PATENT DOCUMENT]]

[0004] [[Patent Document 1]] Japanese National Publication of International Patent Application No. 2018-504797 [Overview of the project] [Problems that the invention aims to solve]

[0005] However, the accessory described in Patent Document 1 uses a ring-shaped handle to tilt a portable device on a table, making the screen easier to view. By rotating the handle 90° and leaving it in that position, the portable device can be tilted in either a portrait or landscape orientation. For this reason, the accessory described in Patent Document 1 has a complex structure, requiring a multi-layered structure, such as installing a guide with fastening grooves in the base to hold the polygonal swing plate of the connecting ring that supports the handle in its rotational position. This inevitably results in a mountain-like protrusion on the back of the portable device. Therefore, even if the connecting block that supports the handle is removed from the base, the accessory causes a mountain-like protrusion in the approximate center of the back of the portable device, resulting in unevenness on the back of the device.

[0006] Therefore, even when attempting to wirelessly charge a portable device equipped with the accessory described in Patent Document 1, the accessory gets in the way, preventing the back of the portable device from being placed on the wireless charger, making wireless charging impossible. Furthermore, when placing the portable device on a table, the accessory gets in the way, making it unstable and causing it to wobble precariously.

[0007] The object of the present invention is to provide an accessory for portable electronic devices that makes it easier to hold the portable electronic device by placing a finger on the ring when using it, and also allows the portable electronic device to be placed on the charging device when wireless charging. [Means for solving the problem]

[0008] The accessory for portable electronic devices according to the present invention is In accessories for portable devices, A flat card holder that attaches to the back of a portable device, The card body that engages with this card holder, It has, The card holder has a flat internal space and a groove on its outer surface that extends from the bottom to the center of the portable device. The card body comprises an upper card plate, a lower card plate, a shaft that fixes the upper and lower card plates parallel to each other with a gap between them, and a ring for gripping a finger that is rotatably attached to the shaft protruding upward from the upper card plate. The card is assembled by inserting the lower card plate into the internal space of the card holder and moving the shaft into the groove. [Effects of the Invention]

[0009] In this invention, the card body can be removed from the card holder by moving the axis of the card body through the groove of the card holder. After the card body is removed, only the card holder remains on the back of the portable electronic device. Furthermore, since the card holder attached to the back of the portable device is flat, when the portable device is placed on a wireless charger which usually has a flat surface, the portable device and the wireless charger can be positioned so that they face each other on their surfaces. As a result, the portable device can be wirelessly charged without any interference from accessories. Furthermore, as described above, since the groove in the card holder is formed to extend from the bottom to the center of the portable electronic device, when the card's axis is moved within the groove and the accessory is assembled, the portable electronic device will attempt to fall when the user holds it with their finger through the ring. However, the axis is locked at the end of the groove and will not move any further, preventing the portable electronic device from detaching from the card and falling. Furthermore, conventional smartphone rings have a thick ring portion and cannot be removed from portable electronic devices, making them incompatible with wireless charging. [Brief explanation of the drawing]

[0010] [Figure 1] (a) is a plan view showing the card holder 3 accessory of this embodiment, and (b) is a front view. [Figure 2] (a) is a plan view showing the card body 2 of the accessory of this embodiment, and (b) is a front view. [Figure 3] (a) is a plan view showing accessory 1 assembled by inserting the card body 2 into the card holder 3, and (b) is a front view. [Modes for carrying out the invention]

[0011] Next, embodiments of the present invention will be described. Figure 1 shows a card holder 3 of accessory 1 of this embodiment. The card holder 3 is flat overall and has a flat space (internal space 3b) inside. The back surface of this card holder 3 is attached to the back surface of a portable device, a smartphone 10, via double-sided tape 4. A groove 3a is formed on the surface of this holder 3, extending from the bottom to the center of the smartphone 10. The thickness of this internal space 3b is, for example, 3 mm or less, and it is preferable to make the card holder 3 as thin as possible by making the thickness of its upper and lower walls as thin as possible while maintaining the necessary strength.

[0012] As shown in Figure 2, in the card body 2 of this embodiment, two flat card upper plates 7 and card lower plates 8 are fixed by a shaft 5 so that they are parallel to each other with a gap between them. A ring 6 for gripping the finger is rotatably provided on the portion of the shaft 5 that protrudes upward from the card upper plates 7. The length of the shaft 5 is, for example, 20 to 30 mm so that it protrudes upward from the card holder 3.

[0013] The accessory 1 is assembled by inserting the lower card plate 8 of the card body 2, configured as described above, into the internal space 3b of the card holder 3. Specifically, the lower card plate 8 of the card body 2 is inserted into the internal space 3a of the card holder 3, and the shaft 5 is inserted into the groove 3a. Then, the shaft 5 is moved towards the center of the smartphone 10 within the groove 3a. As a result, the ring 6 supported at the upper end of the shaft 5 is positioned approximately in the center of the back of the smartphone 10 and is rotatably supported by the shaft 5, making it easier to hold the smartphone 10 when making a phone call using the smartphone 10 by placing a finger on the ring 6. At this time, the upper card plate 7 and the lower card plate 8 sandwich the upper wall of the card holder 3, so the card body 2 can firmly hold the card holder 3 without any looseness, and by holding the card body 2 with a finger on the ring 6, the card holder 3 and the smartphone 10 attached to the card holder 3 with double-sided tape 4 can be securely held.

[0014] Furthermore, since the shaft 5 is locked at the closed end of the groove 3a which is closed near the center of the smartphone 10, even if the load of the smartphone 10 is applied to the card body 2, as long as the ring 6 is held with the fingers, the smartphone 10 will not slip from your hand and fall.

[0015] Then, when wirelessly charging the smartphone 10, the card body 2 is moved to the slot side of the card body 2 in the card holder 3 and removed from the card body 2. In this state, only a flat, thin card holder 3 remains on the back of the smartphone 10, and when the smartphone 10 is placed on the wireless charger, the smartphone 10 faces the wireless charger at a short distance and almost parallel to it. Therefore, wireless charging of the smartphone 10 is possible without any problems.

[0016] The accessory 1 and the card holder 3 shown in Figure 3 have sizes that substantially match the size of the back surface of the smartphone 10. However, the present invention is not limited thereto, and the card holder 3 may have various sizes, for example, the size of the card holder 3 may be half the size of the back surface of the smartphone 10. The card holder 3 has a flat shape, and it is only required that the card holder 3 does not tilt the smartphone 10 when the back side of the smartphone 10 is placed on a flat wireless charger.

[0017] Further, the card holder 3 is fixed to the back surface of the smartphone 10 by the double-sided tape 4. However, the present invention is not limited to double-sided tape, and as long as there is no obstacle to wireless charging, for example, magnets may be arranged at the four corners of the card holder 3 and fixed using such magnets.
