Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the accessory of Patent Document 1 uses a ring-shaped handle to tilt and install the portable device on the table to make the screen of the portable device easier to view. If the handle is rotated 90° and held in that position, the portable device can be selected to be in a vertically long state or a horizontally long state and tilted differently. Therefore, for the accessory of Patent Document 1, it is necessary to install a guide provided with a fastening groove for holding the polygonal swing plate of the connecting ring supporting the handle in its rotating position inside the base. The structure is complex and needs to be a multi-layer structure, and the back surface of the portable device has to be in a shape that bulges like a mountain. For this reason, even if the connecting block supporting the handle is pulled out from the base, due to the accessory, a portion that bulges like a mountain is formed in the approximate center of the back surface of the portable device, and unevenness occurs on the back surface of the portable device.

[0006] Therefore, even when trying to wirelessly charge a portable device equipped with the accessory of this Patent Document 1, the accessory part gets in the way and the back surface of the portable device cannot be overlapped on the wireless charger, making wireless charging impossible. Also, when placing the portable device on the table, the accessory part gets in the way, making it unstable and causing it to be placed in a wobbling state.

[0007] An object of the present invention is to provide an accessory for a portable electronic device that makes it easy to hold the portable electronic device by hanging a finger on a ring during use, and that allows the portable electronic device to be set on a charging device during wireless charging.

Means for Solving the Problems

[0008] An accessory for a portable electronic device according to the present invention is In the accessory for a portable device, a flat card holder attached to the back surface of the portable device, and A card body that engages with this card holder, and has, The card holder has a flat internal space and a groove on the outer surface that extends from the lower part to the center of the portable device. The card body includes a card upper plate, a card lower plate, a shaft that fixes these card upper plate and card lower plate in parallel with a gap therebetween, and a ring for hooking a finger that is rotatably attached to a shaft protruding upward from the card upper plate. It is characterized in that the card lower plate is inserted into the internal space of the card holder, and the shaft is moved into the groove for assembly.

Advantages of the Invention

[0009] In the present invention, since the shaft of the card body moves in the groove of the card holder, the card body can be removed from the card holder. After removing the card body, only the card holder exists on the back surface of the portable electronic device. And since the card holder attached to the back surface of the portable device is flat, usually, when the portable device is placed on a wireless charger having a flat surface, the portable device and the wireless charger can be arranged in a state where they face each other with their surfaces. Therefore, the portable device can be wirelessly charged without interference from accessories. Also, as described above, since the groove of the card holder is formed to extend from the lower part to the center of the portable electronic device, when the shaft of the card body is moved in the groove and the accessory is assembled, when the finger is hooked on the ring and the portable electronic device is held, the portable electronic device tends to fall, but the shaft is locked at the end of the groove and does not move further, so the portable electronic device does not detach from the card body and fall. Note that in a conventional smartphone ring, the ring part has a thickness and cannot be removed from the portable electronic device, so it is not compatible with wireless charging.

Mode for Carrying Out the Invention

[0011] Next, an embodiment of the present invention will be described. FIG. 1 shows the card holder 3 of the accessory 1 according to this embodiment. The card holder 3 is entirely flat plate-shaped and has a flat plate-shaped space (internal space 3b) inside. The back surface of this card holder 3 is attached to the back surface of the smartphone 10, which is a portable device, via a double-sided tape 4. A groove 3a extending from the lower part to the center of the smartphone 10 is formed on the front surface of this holder 3. The thickness of this internal space 3b is, for example, 3 mm or less, and the thickness of the card holder 3 is preferably made as thin as possible while maintaining the necessary strength of the plate thickness of its upper wall and lower wall, so as to configure the card holder 3 to be thin.

[0012] As shown in FIG. 2, in the card body 2 of this embodiment, two flat plate-shaped card upper plates 7 and card lower plates 8 are fixed by a shaft 5 so as to be parallel to each other with a space therebetween. And a ring 6 for hanging a finger is provided rotatably with respect to the shaft 5 at a portion of the shaft 5 protruding upward from the card upper plate 7. The length of the shaft 5 is, for example, 20 to 30 mm in order to protrude upward from the card holder 3.

[0013] The card lower plate 8 of the card body 2 configured as described above is inserted into the internal space 3b of the card holder 3, and the accessory 1 is assembled. That is, the card lower 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 within the groove 3a toward the center side of the smartphone 10. As a result, the ring 6 supported by the upper end portion of the shaft 5 is positioned at approximately the center of the back surface of the smartphone 10 and is rotatably supported by the shaft 5. Therefore, when making a phone call using the smartphone 10, by placing a finger on the ring 6, it becomes easier to hold the smartphone 10. At this time, the upper wall of the card holder 3 is sandwiched between the card upper plate 7 and the card lower plate 8, so the card body 2 can firmly hold the card holder 3 without rattling. If a finger is placed on the ring 6 to hold the card body 2, the card holder 3 and the smartphone 10 attached to the card holder 3 with the double-sided tape 4 can be securely held.

[0014] Further, since the shaft 5 is locked at the closed end of the groove 3a 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 a finger, the smartphone 10 will not leave the hand and fall.

[0015] And when wirelessly charging the smartphone 10, the card body 2 is moved to the insertion port side of the card body 2 in the card holder - 3 and removed from the card body 2. Then, only the flat and thin card holder 3 exists on the back surface of the smartphone 10. When the smartphone 10 is placed on a wireless charger, the smartphone 10 will face the wireless charger approximately parallel with a short distance. For this reason, wireless charging of the smartphone 10 can be performed without any problems.

[0016] The accessory 1 and the card holder 3 shown in FIG. 3 have sizes that approximately match the size of the back surface of the smartphone 10. However, the present invention is not limited thereto, and the size of the card holder 3 can be various sizes, such as half the size of the back surface of the smartphone 10. The card holder 3 has a flat shape, and as long as it does not tilt the smartphone 10 when the back surface side of the smartphone 10 is placed on a flat wireless charger.

[0017] Also, 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 the double-sided tape. As long as there is no obstacle to wireless charging, for example, magnets can be arranged at the four corners of the card holder 3 and fixed using these magnets or the like.
