Description

[DESCRIPTION] [Invention Title] ACCESSORY FOR MOBILE DEVICE [Technical Field] [1] The present disclosure relates to an accessory for a mobile device that is used by being attached to a mobile device or a casing that surrounds the mobile device. Background Art [2] With the proliferation of mobile devices such as smartphones or tablet PCs, various types of accessories for a mobile device have been proposed. Appropriate accessories, such as finger rings or card holders, are most often used by users, as necessary, by being coupled to rear surfaces of the mobile devices or mobile device casings. [3] A comparatively initial accessory has a coupling surface coupled to an outer peripheral surface of the mobile device casing, and a double-sided tape having a bonding force is provided on the coupling surface, such that the accessory is bonded and coupled to the outer peripheral surface of the mobile device casing by means of the double-sided tape. A coupling method using the double-sided tape advantageously provides an excellent coupling force and is easy to use. However, in case that the accessory bonded and coupled to the mobile device casing is detached, the bonding force of the double-sided tape significantly decreases, which makes it difficult to couple the detached accessory to the mobile device casing again. That is, the coupling method using the double-sided tape in the related art has a fatal drawback in that it is difficult to attach or detach the accessory, as necessary. Further, there is also a problem in that it is not easy to perform a process of detaching the coupled accessory and attaching a new accessory. Έ ď [5] Meanwhile, recently, a mobile device casing, which is equipped with a magnet, and an accessory, which has a coupling surface on which a magnet with an opposite polarity is disposed to be coupled to the magnet of the mobile device casing by a magnetic force, have been proliferated and proposed to provide a shape in which the accessory may be quickly and easily coupled to the mobile device casing. [6] However, in the case of the accessory having the coupling structure using the magnet, because a force applied in a vertical direction in which different poles pull each other is strongly applied because of the nature of the magnet, a coupling force applied in the vertical direction is high, but a coupling force applied in a lateral direction by an external force is low, which causes a problem in that a coupling state of the mobile device and the accessory cannot be stable. [7] In addition, because the accessory having the coupling structure using the magnet needs to have the magnet, a thickness or volume of the accessory increases, and the accessory cannot provide a special function, which causes a problem in that the accessory is necessarily implemented so that an auxiliary accessory, such as a Griptok, a finger ring, a handle, or a card holder, needs to be additionally provided. [Disclosure] Technical Problem [8] A first object of the present disclosure is to propose an accessory for a mobile device implemented to have a thin, compact structure that uses a magnetic force as a means for allowing the accessory to be coupled to a mobile device or a mobile device casing. [9] A second object of the present disclosure is to propose an accessory for a mobile 3 device, which is capable of being coupled to a mobile device or a mobile device casing by means of a magnetic force, serving to allow a user to mount the mobile device and hold the mobile device with fingers even in a state in which no auxiliary accessory is Ŷ 10 present, and having an excellent function as a mobile device accessory.

[10] A third object of the present disclosure is to propose an accessory for a mobile device, which is capable of being easily attached to or detached from a mobile device or a mobile device casing and providing a more stably coupled state in a state in which the accessory is coupled to the mobile device or the mobile device casing.

[55] An accessory 100 for a mobile device proposed by the present disclosure includes a first body 110 and a second body 120.

[56] The first body 110 is formed to be attachable, by a magnetic force, to a mobile device or a casing 200 configured to surround the mobile device. For example, as described below, the first body 110 may be implemented in a shape in which a first magnet part 112 made by coupling a plurality of unit magnets is assembled to a magnet holder 111 so that the first body 110 is attached to the casing 200 by the magnetic force.

[57] In this case, an accessory coupling magnet 210, which has a polarity opposite to a polarity of the first magnet part 112 of the first body 110, may be installed on the mobile device, which is coupled to the first body 110 by the magnetic force, or installed on the casing 200 configured to surround the mobile device. ٠, ï 1 ٦ For example, in case that the first magnet part 112 is configured as an N-pole magnet, the accessory coupling magnet 210 may be configured as an S-pole magnet. In addition, in case that the first magnet part 112 is configured as an S-pole magnet, the accessory coupling magnet 210 may be configured as an N-pole magnet. That is, the first magnet part 112 and the accessory coupling magnet 210 may be respectively an N-pole and an S-pole or conversely may be respectively an S-pole and an N-pole. In addition, in case that the first body 110 is implemented in the shape in which the first magnet part 112 made by coupling the plurality of unit magnets is assembled to • the magnet holder 111, a galvanized steel sheet or a metal steel sheet 112a made of stainless (SUS) or the like may be further provided between the magnet holder 111 and the first magnet part 112, for example. The metal steel sheet 112a serves to generate a more stable magnetic force by boosting a magnetic force of the first magnet part 112. In this case, the magnet holder 111 may have a finishing film 113 to close an insertion groove 111d into which the first magnet part 112 is inserted. The second body 120 is connected to the first body 110 so as to be rotatable relative to the first body 110 by a hinge 130. That is, the second body 120 may be connected to the first body 110 through the hinge 130 and moved to be relatively rotatable at a predetermined angle 0 by the hinge 130 in a state in which the first body 110 is attached. to the mobile device or the casing 200 configured to surround the mobile device. In addition, the second body 120 is formed to accommodate at least a part of the first body 110. That is, the second body 120 may have a body accommodation portion 121 to accommodate the first body 110, as described below.

[62] Therefore, as the first body 110 and the second body 120 relatively rotate about the hinge 130, the first body 110 may be accommodated in the second body 120 or withdrawn from the second body 120 in the state in which the first body 110 is attached 3 to the mobile device.

[63] As described above, the structure in which the first body 110 is accommodated in the second body 120 or withdrawn from the second body in the state in which the first body 110 is attached to the mobile device may allow the accessory 100 for a mobile device to have a simple, compact structure, minimize an increase in volume of the mobile device, and provide a compact structure and improved gripping properties even in the state in which the accessory 100 for a mobile device is attached to the mobile device.

[64] In addition, as the first body 110 and the second body 120 relatively rotate about the hinge 130, an angle between the second body 120 and the mobile device varies, or the angle <semantics>θ<annotation encoding="application / x-tex">\theta< / annotation>< / semantics> between the second body 120 and the casing varies. Therefore, as illustrated in FIG. 10, the second body 120 may serve to support the mobile device and serve as a handle, which is gripped by the user's hand, by using the angle <semantics>θ<annotation encoding="application / x-tex">\theta< / annotation>< / semantics> between the second. body 120 and the mobile device.

[65] The hinge 130 includes a first part 131, a second part 132, and a hinge shaft 133.

[66] The first part 131 is coupled to the first body 110. In this case, the structure in which the first part 131 is coupled to the first body 110 is not specially limited. For example, it is possible to apply a coupling structure selected from a group consisting of an interference-fit coupling structure using a protrusion and a groove, a coupling structure using a bolt and a nut, and a coupling structure using a bonding agent or a bonding film.

[67] In this regard, FIG. 2B illustrates a coupling structure using rivets 134 as a structure in which the first part 131 and the first body 110 are coupled. That is, the first body 110 and the first part 131 of the hinge 130 are coupled as the rivets 134 penetrate first fitting holes 131c formed in the first part 131 and are inserted into and fixed to rivet ďΤ fixing grooves 111b formed in the first body 110.

[68] In this case, the first part 131 of the hinge 130 includes a first hinge shaft connection portion 131a into which the hinge shaft 133 is inserted, a first wing portion 131b seated on a hinge seating portion 111a of the first body 110, and the first fitting holes 131c.

[69] The second part 132 is coupled to the second body 120. For example, a coupling structure, which is identical to a coupling structure between the first part 131 and the first body 110, may be applied as a coupling structure between the second part 132 and the second body 120. 2.

[70] However, as illustrated in FIG. 2B, the second part 132 of the hinge 130 may include second hinge shaft connection portions 132a into which the hinge shaft 133 is inserted, and a second wing portion 132b disposed on and coupled to the body accommodation portion 121 of the second body 120. That is, the second wing portion 132b of the second part 132 has a shape and a size corresponding to those of the first body 110 and is disposed on the body accommodation portion 121 of the second body 120, such that the second part 132 and the second body 120 may be coupled.

[71] As described above, the second wing portion 132b having the shape and the size corresponding to those of the first body 110 may maximize an area of a portion tightly attached to the second body 120, such that a more secure coupled state may be implemented between the first part 132 and the first body 120.

[72] In this case, for example, a bonding film 140 may be disposed on the body accommodation portion 121, or a bonding agent may be applied onto the body accommodation portion 121 so that the body accommodation portion 121 and the second wing portion 132b are coupled.

[73] FIGS. 3A and 3B are perspective views illustrating an accessory for a mobile device according to a second embodiment proposed by the present disclosure when viewed 1 from one side and the other side.

[74] FIG. 4A is an exploded view illustrating a bottom side of the accessory for a mobile device in a state in which all components of the accessory for a mobile device in FIG. 3A are disassembled.

[75] FIGS. 4B and 4C are a perspective view and a bottom perspective view illustrating a state in which all the components of the accessory for a mobile device in FIG. 3A are disassembled.

[76] FIG. 5 is an exploded plan view illustrating a state in which all the components of the accessory for a mobile device in FIG. 3A are disassembled.

[77] With reference to FIGS. 3 to 5, in the accessory 100 for a mobile device according to the second embodiment of the present disclosure, the first magnet part 112 is provided on the first body 110, and a second magnet part 122a is provided on the second body 120.

[78] The first magnet part 112 is disposed along a circumference or an elliptical or polygonal rim on the first body 110 and assembled to the magnet holder 111. In this case, for example, the first magnet part 112 may be disposed to have a structure in which a plurality of arcuate unit magnets are alternately disposed and define a circumference shape so that N-poles and S-poles apply attractive forces to one another: In this case, the magnet holder 111 has the insertion groove 111d into which the first magnet part 112 is inserted.

[79] The second magnet part 122a is formed in a linear shape extending in a longitudinal direction of the second body 120. Therefore, the second body 120 has a second magnet part accommodation groove 122 that accommodates the second magnet part 122a.

[80] The second magnet part 122a may serve as a kind of guide magnet to allow the second 23 body 120 to be coupled to an exact position on the mobile device or the casing 200, which is configured to surround the mobile device, in order to maintain a stable fixed state. Therefore, an accessory guide magnet 220 may be installed on the mobile device or the casing 200 configured to surround the mobile device, and the accessory guide magnet 220 may be installed at a position corresponding to the position of the second magnet part 122a and have a polarity opposite to the polarity of the second magnet part 122a.

[81] In addition, the accessory guide magnet 220 may be formed in a linear shape so as to be consistent with the shape of the second magnet part 122a, such that the second body 120 may be more smoothly coupled to an exact position by the second magnet part 122a.

[82] In addition, in case that the second magnet part 122a is configured as an N-pole magnet, the accessory guide magnet 220 may be configured as an S-pole magnet. In addition, in case that the second magnet part 122a is configured as an S-pole magnet, the accessory guide magnet 220 may be configured as an N-pole magnet. That is, the second magnet part 122a and the accessory guide magnet 220 may be respectively an N-pole and an S-pole or conversely may be respectively an S-pole and an N-pole.

[83] Meanwhile, the first magnet part 112 may be disposed on the second body 120 so as to be positioned to be closer to the hinge 130 than the second magnet part 122a to the hinge 130. That is, because the first magnet part 112 is disposed to be closer to the hinge 130 than the second magnet part 122a to the hinge 130, the first body 110 may be withdrawn from the second body 120 by a smaller amount of force, in comparison with a case in which the second magnet part 122a is disposed to be closer to the hinge 130 than the first magnet part 112 to the hinge 130, in case that the first body 110 is withdrawn from the second body 120 and relatively rotated about the hinge 130. ٠. Therefore, the first body 110 and the second body 120 may more smoothly rotate relative to each other. 4

[84] The hinge 130 includes the first part 131, the second part 132, and the hinge shaft 133.

[85] The first part 131 is coupled to the first body 110. In this case, the structure in which the first part 131 is coupled to the first body 110 is not specially limited. For example, it is possible to apply a coupling structure selected from a group consisting of an interference-fit coupling structure using a protrusion and a groove, a coupling structure using a bolt and a nut, and a coupling structure using a bonding agent or a bonding film.

[86] In this regard, FIG. 4B illustrates an interference-fit coupling structure using protrusions 111b and the first fitting holes 131c as the structure in which the first part • 131 and the first body 110 are coupled. That is, the coupling between the first body 110 and the first part 131 of the hinge 130 is achieved by the coupling between the protrusion 111b formed on the first body 110 and the first fitting hole 131c formed in the first part 131.

[87] In this case, the first part 131 of the hinge 130 includes the first hinge shaft connection portion 131a into which the hinge shaft 133 is inserted, the first wing portion 131b seated on the hinge seating portion 111a of the first body 110, and the first fitting holes 131c.

[88] The second part 132 is coupled to the second body 120. For example, a coupling structure, which is identical to the coupling structure between the first part 131 and the first body 110, may be applied as the coupling structure between the second part 132 and the second body 120. 1

[89] In this regard, in FIGS. 4B and 4C, a bracket 141 and first grooves 124a and a second groove 123b of the second body 120 are provided to couple the second part 132 and ١ ٠; 9; 1 the second body 120.

[90] Specifically, the second groove 123b is formed in a hinge accommodation portion 123 formed in one surface of the second body 120. The second groove 123b communicates with the first groove 124a formed in a bracket accommodation portion 124 formed in the other surface of the second body 120 to be described below. Therefore, the first groove 124a and the second groove 123b communicate with each other and define a passageway penetrated by protruding coupling portions 141a of the bracket 141.

[91] The protruding coupling portion 141a of the bracket 141 penetrates the first groove 124a and the second groove 123b, such that an end of the protruding coupling portion 141a is exposed to the outside of the second groove 123b. The end of the protruding coupling portion 141a is coupled, in an interference-fit manner, to a second fitting hole 132c formed in the second part 132 of the hinge 130, such that the second body 120 and the second part 132 are coupled.

[92] In this case, the second part 132 of the hinge 130 includes the second hinge shaft connection portion 132a into which the hinge shaft 133 is inserted, the second wing portion 132b seated on the hinge accommodation portion 123 of the second body 120, and the second fitting hole 132c.

[93] Meanwhile, the first part 131 and the second part 132 may overlap each other in the state in which the first body 110 is accommodated in the second body 120.

[94] That is, in the state in which the first body 110 is accommodated in and overlaps the second body 120, the first part 131 and the second part 132 are not coupled to outer surfaces thereof, but the first part 131 and the second part 132 are disposed between the first body 110 and the second body 120 and overlap each other. Therefore, based on the hinge shaft 133, the first part 131 and the second part 132 may be implemented. b r ٠. as simple structures with minimized volumes and connect the first body 110 and the second body 120, such that a stable coupling structure may be implemented between the first body 110 and the second body 120, an aesthetic appearance of the accessory 100 for a mobile device may be improved, and a more compact structure may be implemented. In addition, at least a part of the first part 131 of the hinge 130 is covered by the first body 110 in the state in which the first body 110 is accommodated in the second body 120. That is, the accessory 100 for a mobile device has a structure in which the first part 131 of the hinge 130 is covered by the first body 110 even in a state in which the accessory 100 is not attached to the mobile device or the casing 200 of the mobile device, such that the accessory 100 is implemented to have a structure in which only the hinge shaft 133 is simply visible to the outside. Therefore, it is possible to further improve an aesthetic appearance of the accessory 100 for a mobile device. In addition, the structure in which at least a part of the first part 131 is covered by the first body 110 as described above may advantageously minimize an influence on the hinge 130, such as external contaminants, humidity, or a change in temperature, thereby more stably maintain durability and performance of the hinge 130.

[97] Meanwhile, the hinge seating portion 111a of the first body 110 for mounting the hinge 130 at the exact position may be formed in a debossed shape.

[98] The hinge seating portion 111a of the first body 110 may allow a process of coupling the first body 110 and the hinge 130 to be more easily performed during a process of assembling the accessory 100 for a mobile device. The hinge seating portion 111a may eliminate a step difference between the first body 110 and the coupled portion when the first body 110 and the first part 131 of the hinge 130 are coupled, such that a more stably coupled state may be provided between the first body 110 and the first part 131. In addition, the hinge seating portion 111a advantageously achieves a more compact structure by improving spatial utilization between the components of the accessory 100 for a mobile device.

[99] In this case, guide stepped portions 111c may be formed at two opposite sides of the hinge seating portion 111a. The guide stepped portion 111c may allow the first part 131 of the hinge 130 to be more easily seated on the hinge seating portion 111a during the process of assembling the accessory 100 for a mobile device, thereby improving the efficiency in manufacturing the accessory 100 for a mobile device.

[100] The second body 120 includes the body accommodation portion 121 and the hinge accommodation portion 123.

[101] The body accommodation portion 121 is configured to accommodate the first body 110 and formed on one surface of the second body 120 while having a size and a shape corresponding to the size and the shape of the first body 110. The body accommodation portion 121 may minimize a step difference or a change in volume that may occur between the first body 110 and other portions of the second body 120, except for the body accommodation portion 121, in the state in which the first body 110 is accommodated in the second body 120, thereby improving the structural stability of the accessory 100 for a mobile device and implementing a compact external •. appearance.

[102] The hinge accommodation portion 123 is a portion to which the second part 132 of the hinge 130 is coupled, i.e., a portion that accommodates and surrounds the hinge 130 together with the hinge seating portion 111a of the first body 110 in the state in which the first body 110 is accommodated in the second body 120.

[103] Therefore, the hinge accommodation portion 123 may allow the process of coupling the second body 120 and the hinge 130 to be more easily performed during the process . 1 of assembling the accessory 100 for a mobile device. The hinge accommodation portion 123 may eliminate a step difference between the second body 120 and the coupling portion when the second body 120 and the second part 132 of the hinge 130 are coupled, such that a more stably coupled state may be provided between the second body 120 and the second part 132. In addition, the hinge accommodation portion 123 advantageously achieves a more compact structure by improving spatial utilization between the components of the accessory 100 for a mobile device.

[104] In addition, two opposite sides of the hinge accommodation portion 123 may be formed as inclined surfaces 123a to allow a relative rotation between the first body 110 and the second body 120 may be more smoothly performed by a relative rotation between the first part 131 and the second part 132 of the hinge 130, such that the hinge may be more conveniently mounted on the second body 120.

[105] In this case, the body accommodation portion 121 and the hinge accommodation portion 123 may be formed in one surface of the second body 120 and communicate with each other. Therefore, the hinge accommodation portion 123 may be formed in one surface of the second body 120 and overlap a part of the body accommodation portion 121, such that the process of manufacturing the accessory 100 for a mobile device may be simplified, and a portion where a thickness of the second body 120 is entirely reduced may be minimized, thereby minimizing a phenomenon in which the rigidity for performing the function of the second body 120 deteriorates.

[106] In addition, the second body 120 may have a structure including a long side and a short side. That is, for example, the second body 120 has a rectangular shape having long sides and short sides in a plan view. In addition, in the rectangular shape having the long sides and the short sides as illustrated in FIG. 4, one short side may be formed as a straight short side, and the other short side may have a semi-circular round shape. 1

[107] In this case, the hinge accommodation portion 123 may be formed to be opened toward one short side of the second body 120. The structure in which the hinge accommodation portion 123 is opened toward one short side of the second body 120 as described above may have an advantage in that the first part 131 of the hinge 130 smoothly rotates to an obtuse angle range relative to the second part 132 even in case. that the first body 110 and the second body 120 rotate about the hinge 130 relative to each other, and an angle between the first body 110 and the second body 120 is which is an obtuse angle range.

[108] Meanwhile, the second body 120 is formed in a plate shape, and the second magnet part accommodation groove 122 is formed in one surface of the second body 120, together with the body accommodation portion 121, and accommodates the second magnet part 122a. The bracket accommodation portion 124 is formed in the other surface, i.e., a rear surface of one surface in which the hinge accommodation portion 121 is formed, and the bracket 141 configured to more stably couple and fix the hinge 130 to the second body 120 is installed in the bracket accommodation portion 124.

[109] In this case, in order to accommodate the bracket 141, a rim of the bracket accommodation portion 124 is formed to be slightly larger in thickness than other portions of the other surface of the second body 120, and the thickness may define an inclined surface 126, as illustrated in FIG. 3A, so that the rim of the bracket accommodation portion 124 is softly connected to the other surface of the second body 14 120.

[110] In addition, an auxiliary accessory installation portion 125 for installing an auxiliary accessory 160 may be formed in the other surface of the second body 120. As illustrated in FIG. 5, in the accessory 100 for a mobile device according to the second embodiment of the present disclosure, the auxiliary accessory 160 configured as a 40 • Griptok including an expansion socket 161 and an upper end cap 162 is provided as an example.

[116] With reference to FIGS. 6 to 8, in comparison with the accessory 100 for a mobile device according to the second embodiment, in the accessory 100 for a mobile device according to the third embodiment of the present disclosure, a bracket 142 formed on the second body 120 is disposed on the body accommodation portion 121, which is formed in one surface of the second body 120, together with the first body 110. In this case, the bracket 142 includes a bracket body 142a accommodated in the body accommodation portion 121, and a hinge coupling portion 142b formed on one side rim of the bracket body 142a so that the hinge 130 is coupled to the hinge coupling portion 142b.

[117] In the third embodiment, the bracket 142 configured to more stably couple the hinge 130 to the second body 120 is installed in the body accommodation portion 121 of the second body 120. Specifically, in the accessory 100 for a mobile device according to the third embodiment, the bracket 142 is disposed on the second body 120 first, and then the second part 132 of the hinge 130 is coupled to the hinge coupling portion 142b. Thereafter, the first body 110 is coupled and assembled to the first part 131 of the hinge 130.

[118] In this case, for example, a bonding film (not illustrated) may be disposed on the body accommodation portion 121, or a bonding agent may be applied onto the body accommodation portion 121 so that the body accommodation portion 121 and the bracket 142 are coupled.

[119] As in the third embodiment, in case that the bracket 142 is provided in the body accommodation portion 121 of the second body 120, the bracket accommodation portion 124 may be excluded without being separately formed in the other surface of the second body 120, unlike the second embodiment, such that the process of manufacturing the accessory 100 for a mobile device may be simplified, and the accessory 100 for a mobile device having a simpler shape may be implemented.

[120] In addition, in the accessory 100 for a mobile device according to the third embodiment, the bracket accommodation portion 124 may be excluded without being separately formed in the other surface of the second body 120, the accessory 100 for a mobile device, which has an entirely constant thickness, may be implemented in comparison with the accessory 100 for a mobile device according to the second embodiment.

[121] In the accessory 100 for a mobile device according to the third embodiment, the hinge 130 includes the first part 131, the second part 132, and the hinge shaft 133.

[122] The first part 131 is coupled to the first body 110. Because the structure in which the first part 131 and the first body 110 are coupled to each other may be applied in the same way as in the second embodiment, a description thereof will be omitted.

[123] The second part 132 is coupled to the hinge coupling portion 142b of the bracket 142 disposed in the body accommodation portion 121 of the second body 120.

[124] Specifically, bracket protrusions 142c are formed on the hinge coupling portion 142b so as to be coupled to the second part 132 of the hinge 130, and the second fitting holes 132c are formed in the second part 132. Therefore, the coupling between the second body 120 and the second part 132 of the hinge 130 is achieved by the coupling between the protrusion 142c formed on the bracket 142 and the second fitting hole 132c formed in the second part 132.

[125] In this case, the second part 132 of the hinge 130 includes the second hinge shaft connection portion 132a into which the hinge shaft 133 is inserted, the second wing portion 132b seated on the hinge accommodation portion 123 of the second body 120, and the second fitting hole 132c.

[126] Meanwhile, as illustrated in FIGS. 7B, 7C, and 8, in the accessory 100 for a mobile device according to the third embodiment of the present disclosure, the auxiliary accessory 160 configured as the Griptok including the expansion socket 161 and the upper end cap 162 is provided as an example.

[133] FIG. 11A is a perspective view illustrating an accessory for a mobile device according to a fourth embodiment proposed by the present disclosure when viewed from one side.

[134] FIG. 11B is a conceptual view illustrating a state in which a finger ring part and a first body of the accessory for a mobile device in FIG. 11A are respectively rotated about hinges and have predetermined angles with respect to a second body.

[135] FIG. 11C is a conceptual view illustrating a bottom side of the accessory for a mobile device in FIG. 11A in a state in which the finger ring part and the first body are respectively rotated about the hinges and have predetermined angles with respect to the second body.

[136] FIG. 11D is a conceptual view illustrating a state in which all components of the accessory for a mobile device in FIG. 11A are disassembled.

[137] FIG. 11E is a conceptual view illustrating a cross-section taken along line A-A' of the . ŧ, accessory for a mobile device in FIG. 11A.

[138] With reference to FIGS. 11A, 11B, 11C, 11D, and 11E, in an accessory 300 for a mobile device, a second body 320 has a through-hole 327 formed at a position corresponding to a vicinity of a center of the first body 310 in a state in which a first body 310 is accommodated. A finger ring assembly 360 is installed in the through- hole 327 of the second body 320 and has a finger ring 363 configured to be rotatable in a direction of a rear surface of a surface in which the first body 310 is accommodated. ٠,

[139] That is, in the accessory 300 for a mobile device, the first body 310 is configured to relatively rotate about a hinge 330 on one surface of the second body 320, and the finger ring 363 is configured to relatively rotate about a finger ring hinge part 362 of the finger ring assembly 360 on the other surface of the second body 320. Therefore, the accessory 300 for a mobile device may allow the user to conveniently grip or fix, with the hand, a mobile device by means of the finger ring 363 of the finger ring assembly 360.

[140] The finger ring assembly 360 includes a finger ring bracket 361, the finger ring hinge part 362, and the finger ring 363. · • .

[141] The finger ring bracket 361 is installed on an inner peripheral surface of the through- hole 327 formed in the second body 320 and configured to be rotatable in a lateral direction about a central axis of a center of the through-hole 327. That is, the finger ring bracket 361 is tightly attached to and mounted on the inner peripheral surface of the through-hole 327 and configured to rotate in the lateral direction parallel to the second body 320 in the state in which the finger ring bracket 361 is mounted in the through-hole 327. Therefore, the finger ring bracket 361 may allow the finger ring 363 to be positioned at various positions parallel to the second body 320 in a state in which the finger ring 363 is withdrawn from the finger ring bracket 361, such that the user may more conveniently grip or hold, with the hand, the mobile device by means of the finger ring 363 and fix the mobile device. In this case, the finger ring bracket 361 may have an O-ring mounting groove 361a formed in an outer peripheral surface thereof in order to implement both a stably tightly attached state and a smooth rotational motion state between the finger ring bracket 361 and the inner peripheral surface of the through-hole 327 of the second body 320. The finger ring bracket 361 may have an O-ring 361b inserted into the O-ring mounting groove 361b.

[143] The finger ring hinge part 362 is formed at one side of the finger ring bracket 361 and has a shape protruding upward. Two opposite sides of the finger ring hinge part 362 are coupled to and overlap a part of the finger ring 363 and connected to the finger ring 363 so that the finger ring 363 may relatively rotate about the finger ring hinge part 362 on the other surface of the second body 320. Therefore, a hinge connection structure with the finger ring 363 is achieved by a hinge shaft pin 362a that penetrates a part of the finger ring 363 in the lateral direction in the state in which the two opposite sides of the finger ring hinge part 362 are coupled to and overlap a part of the finger ring 363. In this case, a pinhole 363a is formed in a part of the finger ring 363 coupled to overlap a part of the finger ring 363 so that the hinge shaft pin 363a penetrates the pinhole 363a laterally.

[144] The finger ring 363 is coupled to the finger ring hinge part 362 and disposed in parallel with the second body 320 or configured to be rotatable in the direction of the rear surface of the surface of the second body 320 in which the first body 310 is accommodated. Therefore, the finger ring 363 may allow the user to more conveniently grip a mobile device (not illustrated) or fix the mobile device (not ١, ٠. illustrated) on the finger in the state in which the accessory 300 for a mobile device is mounted. In this regard, in case that the user uses the mobile device mounted with the accessory 300 for a mobile device, the user rotates the second body 320 relative to the first body 310 from the first body 310 to grip or fix the mobile device with the hand. In this state, when the user holds the second body 320 with the hand and grip or fix the mobile device, the coupling force of the coupled portion of the magnet is decreased on the basis of the principle of the lever in which a distance between the hinge 330, which is a support point, and the contact portion of the second body with the user's finger, which is a force point, becomes longer than a distance between the first body 310, which is a point of action, and a magnet coupling portion with the mobile device casing and the support point because of a size of the second body 320 relatively larger than a size of the first body 310. For this reason, the accessory 300 for a mobile device may be separated from the mobile device, or the coupled state may be weakened. However, in case that the user holds the finger ring 363 with the hand or inserts the finger into the finger ring 363 in order to grip or fix the mobile device with the hand in the state in which the user relatively rotates the finger ring 363 about the finger ring hinge part 362 when the user uses the mobile device mounted with the accessory 300' for a mobile device, the above-mentioned principle of the lever is applied in a reverse way. Therefore, the coupling force between the first body 310 and the mobile device casing may be stably maintained, such that the user may more conveniently grip or fix the mobile device with the hand.

[147] The accessory 300 for a mobile device has the hinge 330 configured to connect the first body 310 and the second body 320. Because the description of the hinge 330 is identical to the description of the hinge 130 of the above-mentioned accessory for a ,1 : ,, mobile device of the second embodiment, the description will be omitted. In addition, because the descriptions of a bracket 341 installed on a rear surface of a portion of the second body 320 to which the hinge 330 and the second body 320 are coupled, a bracket accommodation portion 324 on which the bracket 341 is installed, and an inclined surface 326 formed at a periphery of the bracket accommodation ٠, portion 324 are identical to the descriptions of the bracket, the bracket accommodation portion, and the inclined surface of the accessory for a mobile device of the above- mentioned second embodiment, the descriptions will be omitted. Meanwhile, in case that the first body 310 is implemented in the shape in which the first magnet part 312 made by coupling the plurality of unit magnets is assembled to the magnet holder 311, a galvanized steel sheet or a metal steel sheet 312a made of stainless (SUS) or the like may be further provided between the magnet holder 311 and the first magnet part 312, for example. The metal steel sheet 112a serves to generate a more stable magnetic force by boosting a magnetic force of the first magnet part 112. In this case, the magnet holder 311 may have a finishing film 313 to close an insertion groove 311d into which the first magnet part 312 is inserted. In addition, a second magnet part 322a is provided on the second body 320 and linearly extends in the longitudinal direction. The second magnet part 322a may serve as a kind of guide magnet to allow the second body 320 to be coupled to an exact position on the mobile device or the casing (not illustrated), which is configured to surround the mobile device, in order to maintain a stable fixed state. Therefore, an accessory guide magnet (not illustrated) may be installed on the mobile device or the casing configured to surround the mobile device, and the accessory guide magnet may be installed at a position corresponding to the position of the second magnet part 322a and have a polarity opposite to the polarity of the second magnet part 322a. •

[150] In this case, a metal pad 322aa may be provided between the second magnet part 322a and the second body 320, and a second magnet part finishing film 322c may be provided on an outer surface of the second magnet part 322a.

[151] Meanwhile, as illustrated in FIG. 11E, the second body 320 may have a close contact protrusion 327a formed on an inner peripheral surface of the through-hole 327, which is in contact with an outer peripheral surface of the finger ring bracket 361, and configured to more stably fix the finger ring bracket 361. In this case, the close contact protrusion 327a may be formed at a position corresponding to the position at which the O-ring mounting groove 361a of the finger ring bracket 361 is formed so that the close contact protrusion 327a may be tightly attached to the O-ring 361b, which is provided in the O-ring mounting groove 361a of the finger ring bracket 361, and press the O-ring 361b.
