Description

Technical Field

[0001] The present invention relates to an accessory for a portable device that is used by being attached to a portable device or a case surrounding the portable device.

Background Art

[0002] With the widespread use of portable devices such as smartphones and tablet PCs, various accessories for portable devices have been proposed. Most of such accessories, such as finger rings and card cases, are used in a form where a user couples an appropriate accessory to the back surface of the portable device or the case of the portable device as needed.

[0003] Relatively early accessories were of a form in which a coupling surface to be coupled to the outer peripheral surface of the case of the portable device was formed, a double-sided adhesive tape having adhesive force was provided on the coupling surface, and the accessory was adhesively coupled to the outer peripheral surface of the case of the portable device via the double-sided adhesive tape. However, although the coupling method using a double-sided adhesive tape has the advantages of excellent coupling force and convenient use, when the accessory adhesively coupled to the case of the portable device is removed, the adhesive force of the double-sided adhesive tape is significantly reduced, making it difficult to re-couple the removed accessory to the case of the portable device.

[0004] That is, the conventional coupling method using a double-sided adhesive tape has a fatal drawback that it is difficult to attach and detach the accessory as needed, and there is a problem that the operation of removing the coupled accessory and attaching a new accessory is not easy.

[0005] On the other hand, in recent years, cases for portable devices equipped with magnets, and accessories in which magnets of opposite polarity are arranged on the coupling surface so as to be magnetically coupled with the magnet of the case of the portable device, have become widespread, and a form that allows the accessory to be quickly and easily coupled to the case of the portable device has been proposed.

[0006] However, accessories with such magnetic bonding structures have a problem where, due to the properties of magnets, a strong vertical force acts between opposite poles attracting each other, resulting in a strong bonding force in the vertical direction, but a weak bonding force due to external forces acting from the side, leading to an unstable bond between the portable device and the accessory.

[0007] Furthermore, accessories with a magnetic bonding structure have the drawback that, because they must contain magnets, the accessories themselves become thicker and bulkier, and cannot perform any special function on their own. Therefore, they must always be designed to include auxiliary accessories such as grip tocks, fingerings, handles, or card cases. [Overview of the project] [Problems that the invention aims to solve]

[0008] The first objective of the present invention is to provide an accessory for a portable device that utilizes magnetic force as a means of achieving attachment to a portable device or a case for a portable device, while having a thin and compact structure.

[0009] A second objective of the present invention is to provide a portable device accessory that has excellent functionality as a portable device accessory, as it has a magnetic coupling function to a portable device or a case for a portable device, while also being able to perform a stand function for the portable device and a gripping function using the user's fingers, even without auxiliary accessories.

[0010] A third object of the present invention is to provide an accessory for a portable device that is easy to attach to and detach from a portable device or a case for a portable device, and that provides a more stable connection when attached to the portable device or a case for a portable device. [Means for solving the problem]

[0011] The accessory for portable devices proposed in the present invention includes a first body formed to be attachable to a portable device or a case surrounding the portable device by magnetic force, and a second body connected to the first body by a hinge so as to be rotatable relative to the first body and formed to house at least a portion of the first body, wherein the first body and the second body rotate relative to each other with respect to the hinge, causing the first body to be housed in the second body while attached to the portable device or to be pulled out from the second body, and the angle between the second body and the portable device or between the second body and the case changes as the first body and the second body rotate relative to each other with respect to the hinge.

[0012] The first body is provided with a first magnet portion, and the second body is provided with a second magnet portion. The first magnet portion is arranged along the circumference of the first body or along the edge of an ellipse or polygon, and the second magnet portion is formed in a linear shape extending in the longitudinal direction of the second body.

[0013] The first magnet portion is located closer to the hinge in the second body than the second magnet portion.

[0014] The hinge includes a first part that is coupled to the first body and a second part that is coupled to the second body, and the first part and the second part overlap when the first body is housed in the second body.

[0015] It includes a first part that is coupled to the first body and a second part that is coupled to the second body, wherein at least a portion of the first part is shielded by the first body when the first body is housed in the second body.

[0016] The first main body is further formed in the form of an incised hinge mounting portion for securing the hinge in place.

[0017] The second body includes a body housing portion formed to accommodate the first body and a hinge housing portion formed to accommodate the hinge, and the body housing portion and the hinge housing portion are formed to communicate with each other.

[0018] The second body includes a long side and a short side, and the hinge housing is formed to open to one end face side of the second body.

[0019] The second main body is further provided with a bracket on the back of the main body housing or the hinge housing for connecting with the hinge.

[0020] The second body is formed in a plate shape, with a body housing section formed on one side for housing the first body, and an auxiliary accessory mounting section formed on the other side.

[0021] The second body has a through hole formed at a position corresponding to the center of the first body when the first body is housed in it, and a fingering assembly is installed in the through hole, which is formed in the second body so as to be rotatable in the direction of the back surface of the surface in which the first body is housed.

[0022] The fingering assembly may include a fingering bracket installed on the inner circumferential surface of the through hole and configured to rotate laterally with the center of the through hole as its central axis, with a fingering hinge portion formed on one side to which the fingering is rotatably coupled, and a fingering coupled to the fingering hinge portion and positioned parallel to the second body, or formed in the second body to rotate toward the rear surface of the surface in which the first body is housed. [Effects of the Invention]

[0023] The effects of the present invention obtained by the above-described solution are as follows:

[0024] According to the present invention, it is possible to realize an accessory for a portable device that has a coupling structure utilizing magnetic force, as well as a thin and compact structure, by the configuration of a first main body formed to be attachable to a portable device or a case surrounding the portable device by magnetic force, and a second main body coupled to the first main body by a hinge so as to be rotatable relative thereto.

[0025] In addition, while utilizing the magnetic coupling function for the portable device or the case of the portable device, it is possible to realize an accessory with excellent functionality that can perform both the stand function for the portable device and the gripping function using the user's finger in a composite manner by the second main body itself, without applying any separate auxiliary accessory.

[0026] Furthermore, the accessory for a portable device can be easily attached to and detached from the portable device or the case by magnetic force, and can provide a more stable coupled state when coupled with the portable device or the case of the portable device.

[0035] Figure 2b is a perspective view of all the components of the portable device accessory shown in Figure 1, disassembled.

[0036] Figure 2c is a conceptual diagram showing the components of the first main body of the portable device accessory shown in Figure 1 in a disassembled state.

[0037] The portable device accessory 100 proposed in this invention includes a first main body 110 and a second main body 120.

[0038] The first main body 110 is formed to be attachable to a portable device or a case 200 surrounding a portable device by magnetic force. The first main body 110 may, for example, be configured such that it can be attached to the case 200 by magnetic force, by incorporating a first magnetic section 112 in which a plurality of unit magnets are coupled to a magnet holder 111, as will be described later.

[0039] In this case, an accessory-attaching magnet 210 having an opposite pole to the pole of the first magnetic part 112 of the first main body 110 may be installed on the portable device or the case 200 surrounding the portable device, which is connected to the first main body 110 by magnetic force.

[0040] For example, if the first magnetic part 112 is made of a north-pole magnet, the accessory coupling magnet 210 may be made of a south-pole magnet. Also, if the first magnetic part 112 is made of a south-pole magnet, the accessory coupling magnet 210 may be made of a north-pole magnet. In other words, the first magnetic part 112 and the accessory coupling magnet 210 may be north-pole and south-pole, respectively, or conversely, south-pole and north-pole, respectively.

[0041] Furthermore, if the first main body 110 consists of a first magnet section 112 in which a plurality of unit magnets are coupled to a magnet holder 111, a metal sheet 112a, such as zinc or stainless steel (SUS), may be further provided between the magnet holder 111 and the first magnet section 112. Such a metal sheet 112a boosts the magnetic force of the first magnet section 112, resulting in a more stable magnetic force. Here, the magnet holder 111 may be provided with a finishing film 113 to finish the insertion groove 111d into which the first magnet section 112 is inserted.

[0042] The second body 120 is connected to the first body 110 by a hinge 130 so as to be rotatable relative to it. That is, the second body 120 is connected to the first body 110 via the hinge 130, and the first body 110 can move relative to it by a predetermined angle (θ) via the hinge 130 while the first body 110 is attached to a portable device or a case 200 surrounding the portable device.

[0043] Furthermore, the second body 120 is formed to accommodate at least a portion of the first body 110. That is, the second body 120 may have a body housing portion 121, as described later, that can accommodate the first body 110.

[0044] Therefore, as the first body 110 and the second body 120 rotate relative to each other with respect to the hinge 130, the first body 110 is either housed in the second body 120 or pulled out from the second body 120 while attached to the portable device.

[0045] Thus, the structure in which the first main body 110 is housed in the second main body 120 while attached to the portable device, or pulled out from the second main body, makes the structure of the portable device accessory 100 itself simple and compact, minimizes the increase in the volume of the portable device even when the portable device accessory 100 is attached to the portable device, and provides a compact structure and improved grip.

[0046] Furthermore, as the first body 110 and the second body 120 rotate relative to each other with respect to the hinge 130, the angle (θ) between the second body 120 and the portable device or between the second body 120 and the case changes. Therefore, the second body 120 has the advantage of being able to function as a stand for the portable device by utilizing the angle (θ) between the second body 120 and the portable device, as shown in Figure 10, and also being able to function as a handle that can be gripped by the user's hand.

[0047] The hinge 130 includes a first part 131, a second part 132, and a hinge shaft 133.

[0048] The first part 131 is coupled to the first body 110. Here, the structure to which the first part 131 is coupled to the first body 110 is not particularly limited, and a coupling structure selected from the group consisting of, for example, a press-fit coupling structure using protrusions and recesses, a coupling structure using bolts and nuts, and a coupling structure using adhesive or adhesive film can be applied.

[0049] In connection with this, Figure 2b discloses a coupling structure using a rivet 134 as a coupling structure between the first part 131 and the first body 110. That is, the coupling between the first body 110 and the first part 131 of the hinge 130 is achieved by inserting the rivet 134 through the first insertion hole 131c formed in the first part 131 and into the rivet fixing recess 111b formed in the first body 110, thereby fixing it in place.

[0050] Here, the first part 131 of the hinge 130 includes a first hinge shaft connecting portion 131a into which the hinge shaft 133 is inserted, a first wing portion 131b that is placed on the hinge mounting portion 111a of the first body 110, and a first insertion hole 131c.

[0051] The second part 132 is joined to the second body 120. The joining structure between the second part 132 and the second body 120 can be the same as the joining structure between the first part 131 and the first body 110, for example.

[0052] However, as shown in Figure 2b, the second part 132 of the hinge 130 may consist of a second hinge shaft connecting portion 132a into which the hinge shaft 133 is inserted, and a second wing portion 132b which is positioned and coupled to the body housing portion 121 of the second body 120. That is, the coupling between the second part 132 and the second body 120 is achieved by forming the second wing portion 132b in the second part 132 with a shape and size corresponding to the first body 110 and positioning it in the body housing portion 121 of the second body 120.

[0053] In this way, the second wing portion 132b, which is formed in a shape and size corresponding to the first body 110, maximizes the area of ​​the part that is in close contact with the second body 120, thereby enabling a stronger bond between the first part 132 and the first body 120.

[0054] Here, the main body housing section 121 may, for example, have an adhesive film 140 for bonding with the second wing section 132b, or an adhesive may be applied to it.

[0055] Figures 3a and 3b are perspective views of a portable device accessory according to the second embodiment proposed in the present invention, viewed from one side and the other side.

[0056] Figure 4a is an exploded view showing the bottom view of all the components of the portable device accessory shown in Figure 3a, when they have been disassembled.

[0057] Figures 4b and 4c are perspective views and bottom perspective views, respectively, of the portable device accessory shown in Figure 3a, in a disassembled state.

[0058] Figure 5 is an exploded view showing all the components of the portable device accessory shown in Figure 3a in a disassembled state.

[0059] Referring to Figures 3 to 5, in the accessory 100 for portable devices according to the second embodiment of the present invention, the first main body 110 is provided with a first magnetic part 112, and the second main body 120 is provided with a second magnetic part 122a.

[0060] The first magnet section 112 is arranged along the circumference of the first body 110, or along the edge of an ellipse or polygon, and is incorporated into the magnet holder 111. Here, the first magnet section 112 may be arranged in a circumferential shape, for example, with multiple arch-shaped unit magnets arranged alternately with north and south poles acting attractively towards each other. Here, the magnet holder 111 has an insertion groove 111d into which the first magnet section 112 is inserted.

[0061] The second magnet portion 122a is formed in a linear shape extending in the longitudinal direction of the second body 120. Therefore, the second body 120 has a second magnet portion housing groove 122 for housing such a second magnet portion 122a.

[0062] The second magnetic portion 122a acts as a kind of guide magnet, enabling the second main body 120 to be coupled to a fixed position on the portable device or the case 200 surrounding the portable device and maintain a stable fixed state. Therefore, an accessory guide magnet 220 having the opposite pole to the second magnetic portion 122a may be installed on the portable device or the case 200 surrounding the portable device at a position corresponding to the position of the second magnetic portion 122a.

[0063] Furthermore, the accessory guide magnet 220 is formed in a linear shape to match the shape of the second magnet portion 122a, which allows the second magnet portion 122a to perform its fixed-position coupling function of the second main body 120 more smoothly.

[0064] Furthermore, if the second magnetic part 122a is made of a north-pole magnet, the accessory guide magnet 220 may be made of a south-pole magnet. Also, if the second magnetic part 122a is made of a south-pole magnet, the accessory guide magnet 220 may be made of a north-pole magnet. In other words, the second magnetic part 122a and the accessory guide magnet 220 may be north-pole and south-pole, respectively, or conversely, south-pole and north-pole, respectively.

[0065] On the other hand, the first magnet portion 112 may be positioned closer to the hinge 130 on the second body 120 than the second magnet portion 122a. That is, by positioning the first magnet portion 112 closer to the hinge 130 than the second magnet portion 122a, when the first body 110 is pulled out from the second body 120 and rotates relative to the hinge 130, the first body 110 can be pulled out from the second body 120 with less force than when the second magnet portion 122a is positioned closer to the hinge 130 than the first magnet portion 112, which has the advantage of allowing the relative rotation between the first body 110 and the second body 120 to occur more smoothly.

[0066] The hinge 130 includes a first part 131, a second part 132, and a hinge shaft 133.

[0067] The first part 131 is coupled to the first body 110. Here, the structure to which the first part 131 is coupled to the first body 110 is not particularly limited, and a coupling structure selected from the group consisting of, for example, a press-fit coupling structure using protrusions and recesses, a coupling structure using bolts and nuts, and a coupling structure using adhesive or adhesive film can be applied.

[0068] In connection with this, Figure 4b discloses a crimp-fit ​​coupling structure using a projection 111b and a first insertion hole 131c as a coupling structure between the first part 131 and the first body 110. That is, the coupling between the first body 110 and the first part 131 of the hinge 130 is achieved by coupling the projection 111b formed on the first body 110 with the first insertion hole 131c formed on the first part 131.

[0069] Here, the first part 131 of the hinge 130 includes a first hinge shaft connecting portion 131a into which the hinge shaft 133 is inserted, a first wing portion 131b that is placed on the hinge mounting portion 111a of the first body 110, and a first insertion hole 131c.

[0070] The second part 132 is joined to the second body 120. The joining structure between the second part 132 and the second body 120 can be the same as the joining structure between the first part 131 and the first body 110, for example.

[0071] In connection therewith, referring to Figures 4b and 4c, the bracket 141 and the first recess 124a and second recess 123b of the second body 120 are provided for connecting the second part 132 and the second body 120.

[0072] Specifically, a second recess 123b is formed in the hinge housing portion 123 formed on one surface of the second body 120. This second recess 123b communicates with a first recess 124a formed in the bracket housing portion 124 formed on the other surface of the second body 120, which will be described later. Therefore, the first recess 124a and the second recess 123b communicate to form a passage through which the protruding coupling portion 141a of the bracket 141 passes.

[0073] The protruding coupling portion 141a of the bracket 141 penetrates the first recess 124a and the second recess 123b, with its end exposed to the outside of the second recess 123b. The end of such a protruding coupling portion 141a is interlocked into the second insertion hole 132c formed in the second part 132 of the hinge 130, thereby achieving the connection between the second body 120 and the second part 132.

[0074] Here, the second part 132 of the hinge 130 includes a second hinge shaft connecting portion 132a into which the hinge shaft 133 is inserted, a second wing portion 132b which is placed on the hinge housing portion 123 of the second body 120, and a second insertion hole 132c.

[0075] Alternatively, with the first main body 110 housed in the second main body 120, the first part 131 and the second part 132 may overlap.

[0076] In other words, the first part 131 and the second part 132 are not joined to each other's outer surfaces when the first body 110 is housed and overlapping with the second body 120, but rather are positioned between the first body 110 and the second body 120 so that they overlap each other. Therefore, the first part 131 and the second part 132 are realized with a simple structure with the volume minimized using the hinge shaft 133 as a reference, and a stable connection structure between the first body 110 and the second body 120 can be realized to connect the first body 110 and the second body 120, improving the aesthetics of the portable device accessory 100 itself and enabling a more compact structure.

[0077] Furthermore, when the first body 110 is housed in the second body 120, at least a portion of the first part 131 of the hinge 130 is shielded by the first body 110. In other words, the portable device accessory 100 has a structure in which the first part 131 of the hinge 130 is shielded by the first body 110 even when it is not attached to the portable device or the case 200 of the portable device. This achieves a structure in which only the hinge shaft 133 is simply visible from the outside, thereby further improving the aesthetic appeal of the portable device accessory 100 itself.

[0078] Furthermore, a structure in which at least a portion of the first part 131 is shielded by the first body 110 has the advantage of minimizing the impact of external contaminants, humidity, temperature changes, etc. on the hinge 130, thereby enabling more stable maintenance of the durability and performance of the hinge 130.

[0079] On the other hand, the first main body 110 may have a hinge mounting portion 111a for fixed position mounting of the hinge 130 formed in an engraved form.

[0080] The hinge mounting portion 111a of the first body 110 facilitates the joining process between the first body 110 and the hinge 130 during the assembly process of the portable device accessory 100. When joining the first body 110 and the first part 131 of the hinge 130, it eliminates the step difference between the joining portion and the rest of the first body 110, thereby providing a more stable connection between the first body 110 and the first part 131. Furthermore, the hinge mounting portion 111a has the advantage of increasing the utilization of space between components of the portable device accessory 100, thereby achieving a more compact structure.

[0081] Here, guide steps 111c may be formed on both sides of the hinge mounting portion 111a. Such guide steps 111c can make it easier to place the first part 131 of the hinge 130 onto the hinge mounting portion 111a during the assembly process of the portable device accessory 100, thereby improving the manufacturing efficiency of the portable device accessory 100.

[0082] The second body 120 includes a body housing section 121 and a hinge housing section 123.

[0083] The main body housing section 121 is configured to house the first main body 110 and is formed on one surface of the second main body 120 to have a size and shape corresponding to the size and shape of the first main body 110. Such a main body housing section 121 improves the structural stability of the portable device accessory 100 and enables a compact appearance by minimizing any steps or volume changes that may occur between the first main body 110 and other parts of the second main body 120 other than the main body housing section 121 when the first main body 110 is housed in the second main body 120.

[0084] The hinge housing portion 123 is the part to which the second part 132 of the hinge 130 is connected, and is the part that houses and surrounds the hinge 130 together with the hinge mounting portion 111a of the first body 110 when the first body 110 is housed in the second body 120.

[0085] Therefore, the hinge housing 123 facilitates the joining process between the second body 120 and the hinge 130 during the assembly process of the portable device accessory 100, and when joining the second body 120 and the second part 132 of the hinge 130, it eliminates the step difference between the joining part and the rest of the second body 120, thereby providing a more stable connection between the second body 120 and the second part 132. In addition, the hinge housing 123 has the advantage of increasing the degree of space utilization between the parts of the portable device accessory 100, thereby achieving a more compact structure.

[0086] Furthermore, both sides of the hinge housing 123 are made of inclined surfaces 123a, which allows for smoother relative rotation between the first body 110 and the second body 120 due to the relative rotation of the first part 131 and the second part 132 of the hinge 130, and makes it easier to attach the hinge to the second body 120.

[0087] Here, the main body housing section 121 and the hinge housing section 123 are formed to communicate with each other on one surface of the second main body 120. Therefore, on one surface of the second main body 120, the hinge housing section 123 can be formed overlapping a part of the main body housing section 121, which simplifies the manufacturing process of the portable device accessory 100, minimizes the area where the overall thickness of the second main body 120 is reduced, and minimizes the phenomenon of reduced rigidity necessary for the second main body 120 to perform its function.

[0088] Furthermore, the second body 120 may have a structure that includes a long side and a short side. That is, from a planar viewpoint, the second body 120 may be formed in the shape of a rectangle having a long side and a short side. Also, as shown in Figure 4, in such a rectangular shape having a long side and a short side, one short side may be formed in a straight line and the other short side may be formed in a semicircular shape.

[0089] Here, the hinge housing 123 may be formed to open to one short side of the second body 120. In this structure, where the hinge housing 123 opens to one short side of the second body 120, even when the first body 110 and the second body 120 rotate relative to each other with respect to the hinge 130 and the angle between them falls within the obtuse angle range, the first part 131 of the hinge 130 rotates smoothly relative to the second part 132 within the obtuse angle range.

[0090] On the other hand, the second body 120 is formed in a plate shape, and on one surface, a second magnet part housing groove 122 is formed together with the body housing part 121 to house the second magnet part 122a, and on the back surface of the surface on which the hinge housing part 121 is formed, i.e., the other surface, a bracket housing part 124 is formed where a bracket 141 is installed to more stably connect and fix the hinge 130 to the second body 120.

[0091] Here, the edge of the bracket housing portion 124 is formed to be slightly thicker than other parts on the other side of the second body 120 so as to accommodate the bracket 141, and an inclined surface 126 as shown in Figure 3a is formed so that this thickness smoothly connects with the other side of the second body 120.

[0092] Furthermore, an auxiliary accessory mounting section 125 for mounting an auxiliary accessory 160 may be formed on the other side of the second main body 120. In the accessory 100 for portable devices according to the second embodiment of the present invention, an auxiliary accessory 160 consisting of a grip tock including an expansion socket 161 and an upper end cap 162 is exemplified, as shown in Figure 5.

[0093] Figures 6a and 6b are perspective views of a portable device accessory according to the third embodiment proposed in the present invention, viewed from one side and the other side.

[0094] Figure 7a is an exploded view showing the bottom view of all the components of the portable device accessory shown in Figure 6a, when they have been disassembled.

[0095] Figures 7b and 7c are perspective views and bottom perspective views, respectively, of the portable device accessory shown in Figure 6a, in a disassembled state.

[0096] Figure 8 is an exploded view showing all the components of the portable device accessory shown in Figure 6a in a disassembled state.

[0097] Referring to Figures 6 to 8, the portable device accessory 100 according to the third embodiment of the present invention, compared to the portable device accessory 100 according to the second embodiment, has a bracket 142 formed on the second body 120 which is arranged together with the first body 110 in a body housing portion 121 formed on one surface of the second body 120. Here, the bracket 142 consists of a bracket body portion 142a that is housed in the body housing portion 121 and a hinge coupling portion 142b formed on one side edge of the bracket body portion 142a to which the hinge 130 is coupled.

[0098] In the third embodiment, a bracket 142 for more stably connecting the hinge 130 to the second body 120 is installed in the body housing portion 121 of the second body 120. Specifically, in the portable device accessory 100 according to the third embodiment, the bracket 142 is first placed on the second body 120, then the second part 132 of the hinge 130 is connected to the hinge connection portion 142b. After that, the first body 110 is connected to the first part 131 of the hinge 130 to assemble the accessory.

[0099] Here, the main body housing section 121 may be provided with, for example, an adhesive film (not shown) or an adhesive may be applied as a means for connecting it to the bracket 142.

[0100] As in the third embodiment, when the bracket 142 is provided in the main body housing portion 121 of the second main body 120, another bracket housing portion 124, as in the second embodiment, does not need to be formed on the other side of the second main body 120 and can be omitted. This has the advantage of simplifying the manufacturing process of the portable device accessory 100 and enabling the realization of a portable device accessory 100 with a simpler shape.

[0101] Furthermore, in the third embodiment, the portable device accessory 100 does not have another bracket housing portion 124 formed on the other side of the second main body 120, and can be omitted. Therefore, compared to the portable device accessory 100 of the second embodiment, it is possible to realize a portable device accessory 100 that has the same overall thickness.

[0102] In the accessory 100 for a portable device according to the third embodiment, the hinge 130 includes a first part 131, a second part 132, and a hinge shaft 133.

[0103] The first part 131 is coupled to the first body 110. The structure by which the first part 131 and the first body 110 are coupled can be applied in the same way as in the second embodiment, so a description of that will be omitted.

[0104] The second part 132 is connected to the hinge joint 142b of the bracket 142, which is located in the body housing portion 121 of the second body 120.

[0105] Specifically, a bracket projection 142c is formed on the hinge joint portion 142b for connection with the second part 132 of the hinge 130, and a second insertion hole 132c is formed on the second part 132. Therefore, the connection between the second body 120 and the second part 132 of the hinge 130 is achieved by the connection between the projection 142c formed on the bracket 142 and the second insertion hole 132c formed on the second part 132.

[0106] Here, the second part 132 of the hinge 130 includes a second hinge shaft connecting portion 132a into which the hinge shaft 133 is inserted, a second wing portion 132b which is placed on the hinge housing portion 123 of the second body 120, and a second insertion hole 132c.

[0107] On the other hand, in the accessory 100 for portable devices according to the third embodiment of the present invention, an auxiliary accessory 160 consisting of a grip tock including an expansion socket 161 and an upper end cap 162 is exemplified, as shown in Figures 7b, 7c, and 8.

[0108] Figure 9 is a perspective view showing a portable device accessory according to the first embodiment proposed in the present invention, equipped with various auxiliary accessories.

[0109] Figure 10 is a perspective view showing an accessory for a portable device according to the first embodiment proposed in the present invention, with an auxiliary accessory attached to the portable device.

[0110] Referring to Figures 9 and 10, the portable device accessory 100 proposed in the present invention can be installed in various forms on the other side of the second main body 120. In the portable device accessory 100 of the second and third embodiments described above, an auxiliary accessory 160 consisting of a grip tock including an expansion socket 161 and an upper end cap 162 is exemplified.

[0111] Furthermore, the portable device accessory 100 proposed in the present invention can be fitted with auxiliary accessories such as a handle 163 formed on the other side of the second body 120, a card case 164 formed parallel to the long side direction and an elastic band 164a formed parallel to it, and a card case 165 formed parallel to the short side direction of the second body 120, as shown in Figures 9 and 10.

[0112] Figure 11a is a perspective view from one side of a portable device accessory according to the fourth embodiment proposed in the present invention.

[0113] Figure 11b is a conceptual diagram showing the fingering portion and the first body of the portable device accessory shown in Figure 11a rotating relative to their respective hinges to form a predetermined angle with respect to the second body.

[0114] Figure 11c is a conceptual diagram showing a bottom view of the fingering portion and the first body of the portable device accessory shown in Figure 11a, rotated relative to their respective hinges to form a predetermined angle with respect to the second body.

[0115] Figure 11d is a conceptual diagram showing all the components of the portable device accessory shown in Figure 11a in a disassembled state.

[0116] Figure 11e is a conceptual diagram showing the A-A' cross-section of the portable device accessory shown in Figure 11a.

[0117] Referring to Figures 11a, 11b, 11c, 11d, and 11e, in the portable device accessory 300, the second body 320 has a through hole 327 formed at a position corresponding to the center of the first body 310 when the first body 310 is housed in it. A fingering assembly 360, which includes a fingering ring 363 formed to be rotatable in the direction of the back of the surface in which the first body 310 is housed, is installed in the through hole 327 of the second body 320.

[0118] In other words, in the portable device accessory 300, one side of the second body 320 is configured such that the first body 310 rotates relative to the hinge 330, and the other side of the second body 320 is configured such that the fingering 363 rotates relative to the fingering hinge portion 362 of the fingering assembly 360. Therefore, the portable device accessory 300 can be easily gripped or secured in the hand by the fingering 363 of the fingering assembly 360.

[0119] The fingering assembly 360 includes a fingering bracket 361, a fingering hinge 362, and a fingering 363.

[0120] The fingering bracket 361 is installed on the inner circumferential surface of the through hole 327 formed in the second body 320 and is formed to be rotatable laterally around the center of the through hole 327 as its central axis. That is, the fingering bracket 361 is fitted tightly to the inner circumferential surface of the through hole 327 and is formed to rotate laterally parallel to the second body 320 while fitted to the through hole 327. Therefore, the fingering bracket 361 allows the fingering 363 to be positioned in various positions parallel to the second body 320 when the fingering 363 is pulled out from the fingering bracket 361, so that the user can more easily grip or hold and secure the portable device using the fingering 363.

[0121] Here, the fingering bracket 361 may have an O-ring mounting groove 361a formed on its outer surface, and an O-ring 361b may be inserted into the O-ring mounting groove 361b, so as to achieve both a stable contact state and a smooth rotational movement state between the fingering bracket 361 and the inner circumferential surface of the through hole 327 of the second body 320.

[0122] The fingering hinge portion 362 is formed in a shape that protrudes upward from one side of the fingering bracket 361. The fingering hinge portion 362 is connected such that both sides overlap with a portion of the fingering 363, and the fingering 363 is connected to the fingering 363 so that the fingering 363 rotates relative to the fingering hinge portion 362 on the other side of the second body 320. Thus, the fingering hinge portion 362 is connected such that both sides overlap with a portion of the fingering 363, and a hinge shaft pin 362a penetrates a portion of the fingering 363 laterally, thereby achieving a hinge connection structure with the fingering 363. Here, a pinhole 363a is formed in the portion of the fingering 363 that is connected so as to overlap with a portion of the fingering 363, so that the hinge shaft pin 363a penetrates from the side.

[0123] The fingering 363 is coupled to the fingering hinge portion 362 and positioned parallel to the second body 320, or it is formed to be rotatable in the direction of the back of the surface on which the first body 310 is housed in the second body 320. Thus, the fingering 363 allows the user to more easily grasp or secure a portable device (not shown) with the portable device accessory 300 attached to their finger or the like.

[0124] In connection with this, when a user uses a portable device to which the portable device accessory 300 is attached, if the user holds the second body 320 in their hand while the second body 320 is rotated relative to the first body 310 in order to grasp or secure the portable device, the relative size of the second body 320 compared to the first body 310 causes the distance between the hinge 330, which is the fulcrum, and the part of the second body to which the user's fingers make contact, to be greater than the distance between the magnetic coupling part between the first body 310, which is the point of application, and the fulcrum. Due to the lever principle, the coupling force of the magnetic coupling part decreases, causing the portable device accessory 300 to separate from the portable device or the coupling to weaken.

[0125] However, when a user uses a portable device to which the portable device accessory 300 is attached, if the user holds the portable device in their hand or inserts their fingers while the fingering 363 is rotated relative to the fingering hinge portion 362 in order to grasp or secure the portable device, the lever principle described above is applied in reverse. This has the advantage that the bonding force between the first main body 310 and the case of the portable device is stably maintained, allowing the user to grasp or secure the portable device more easily.

[0126] The portable device accessory 300 is equipped with a hinge 330 that connects the first main body 310 and the second main body 320. The description of the hinge 330 is the same as the description of the hinge 130 of the portable device accessory of the second embodiment described above, so it will be omitted. Furthermore, the description of the bracket 341 installed on the back of the portion of the second main body 320 where the hinge 330 and the second main body 320 are joined, the bracket housing portion 324 in which the bracket 341 is installed, and the inclined surface 326 formed around the bracket housing portion 324 are the same as the description of the bracket, bracket housing portion and inclined surface of the portable device accessory of the second embodiment described above, so it will be omitted.

[0127] On the other hand, if the first main body 310 consists of a first magnet section 312 in which a plurality of unit magnets are coupled to a magnet holder 311, a metal sheet 312a, such as zinc or stainless steel (SUS), may be further provided between the magnet holder 311 and the first magnet section 312. Such a metal sheet 112a boosts the magnetic force of the first magnet section 112, resulting in a more stable magnetic force. Here, the magnet holder 311 may be provided with a finishing film 313 to finish the insertion groove 311d into which the first magnet section 312 is inserted.

[0128] Furthermore, the second main body 320 is provided with a second magnetic portion 322a that extends linearly in the longitudinal direction. Such a second magnetic portion 322a acts as a kind of guide magnet, enabling the second main body 320 to be coupled to a fixed position on the portable device or a case (not shown) surrounding the portable device and maintain a stable fixed state. Therefore, an accessory guide magnet (not shown) having an opposite pole to the second magnetic portion 322a may be installed on the portable device or the case surrounding the portable device at a position corresponding to the position of the second magnetic portion 322a.

[0129] Here, a metal pad 322aa is provided between the second magnet portion 322a and the second main body 320, and a second magnet portion finishing film 322c may be provided on the outer surface of the second magnet portion 322a.

[0130] On the other hand, as shown in Figure 11e, the second body 320 may have a contact projection 327a formed on the inner surface of the through hole 327 that abuts the outer surface of the fingering bracket 361 to more stably fix the fingering bracket 361. Here, the contact projection 327a may be formed at a position corresponding to the position where the O-ring mounting groove 361a of the fingering bracket 361 is formed, so that it can tightly contact and pressurize the O-ring 361b provided in the O-ring mounting groove 361a of the fingering bracket 361.

[0131] The foregoing is merely illustrative, and any person with ordinary skill in the art to which the present invention pertains can make various modifications without departing from the scope of the described embodiments and the technical idea. The aforementioned embodiments can be realized individually or in any combination. [Explanation of symbols]
