Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

Fig. 1 is a perspective view of a portable electronic device mounting device, Fig. 2 is a side view of the portable electronic device mounting device, and Fig. 3 is a front view of the portable electronic device mounting device.

Referring to FIGS. 1, 2 and 3, the portable electronic device mounting device includes a support portion 10 having a back plate formed to be detachably installed in any one of a portable electronic device and a portable electronic device case, A finger mounting portion 30 formed to extend from the upper end of the receiving portion 10 to a height thereof in a height direction so as to be inserted between the fingers; And a body (40) including a part (50).

Here, the portable electronic device and the portable electronic device case will be described in more detail, and the portable electronic device can be used for a mobile phone, a MP3, a PMP, a PDA, a laptop, a mini notebook, a UMPC, a tablet PC, a smart phone, Refers to all portable electronic devices such as portable game devices, electronic dictionaries, and remote controls, and the portable electronic device case means covering and protecting at least one side of the portable electronic device.

The backrest 10 may have various shapes such as a circular shape, an elliptical shape, and a polygonal shape. However, the shape of the back plate 10 may be variously selected, for example, The present invention can be applied to any shape that can be used for applications such as portable electronic devices and portable electronic device cases. Further, as a method used in the known technology, a separate rotating member, a rotating member, a rotating plate, a rotating plate, and the like are additionally attached to the back plate so that the back plate can be rotated or pivoted Of course.

The body (40) is composed of a finger rest (30) and a fixed blade (50). First, the finger mount 30 is formed so as to extend from the upper end of the receiving unit 10 at a predetermined height in the height direction so as to be sandwiched between two adjacent fingers. Here, the two adjacent fingers include thumb, It is preferable to be formed so as to feel the most appropriate grip when the user puts on the index finger, the stop finger, the stop finger and the finger ring.

The fixed wing portion 50 is extended in a shape gradually increasing in width from the upper end surface of the finger mounting portion 30. The fixed wing portion 50 is provided at the upper surface of the fixing portion 30 so as to prevent the two fingers, .

The receiving part 10 and the body 40 are all made of an aluminum material which does not easily change from an external force. In consideration of metal interference in wireless charging, which has recently been used, various known materials such as plastic are used Of course.

Prior to describing a more detailed shape, the direction along the shape will be described in advance.

Referring to the side view shown in FIG. 2, a direction in which the second seating portion 32, which will be described later, is located forward and in the opposite direction to the first seating portion 31, The direction in which the fixed blade portion 50 is positioned is referred to as an upward direction and the direction in which the receiving portion 10 is positioned is referred to as downward.

The finger mount 30 is recessed to be rounded in the height direction from the lower end when viewed from the front. In other words, when viewed from the front, the finger rests 30 are seen in a form similar to the shape of an hourglass. This configuration is suitable for the purpose of fixing two fingers adjacent to the finger mount 30. The finger mount 30 is formed in a shape corresponding to the shape of the finger, And has an effect of being able to be stretched.

When the finger mount 30 is viewed from the side, it is also possible to additionally form a first seating portion 31 which is formed to be recessed to be rounded on the rear side. By forming the first seating portion 31, when the adjacent fingers are fitted to the finger rest 30, the portion between the relatively soft fingers may be in the form of a straight line or may be less pressed or impaired than when the finger is protruded.

At least one second seating portion 32 curvedly embedded along the front surface may be formed on the front surface of the finger mount 30. The second seat portion 32 can be used in conjunction with a separate mounting member.

Since the mounting member includes a column or a hook member having a shape corresponding to the second mounting portion 32, the second mounting portion 32 is attached to the pillar or the hook member, It is possible to mount it by hanging it. For example, in the case where the second seating portion 32 is to be held by the two rows of seating members, two second seating portions 32 corresponding to the respective row shapes are formed on the front side to form two rows of seating members and two 2 seat portion 32 can be coupled to the seat portion 32. Since the seat portion 32 is not easily detached through the engagement, the fixing can be easily continued.

In addition, it is also possible to form the finger mount 30 at a different height. In other words, when the finger is placed on the finger mounting unit 30, the finger mount 30 is rotated in the direction of the arrow F, And the thickness of the fingers is gradually increased from the end to the portion close to the palm of the hand. If the height of the finger mount 30 is gradually increased toward the rear side so as to correspond to the change in the thickness of the finger, a more stable grip feeling can be felt when the finger is inserted.

The fixed blade portion (50) has a reference arc (51) crossing the rear side from the front side of the top side. Referring to FIG. 2, it is characterized in that the width is gradually reduced in both lateral directions around the reference arc 51. The fixed wing portion 50 is formed at a predetermined height on the upper surface of the finger mounting portion 30. The fixed wing portion 50 has a reference arc 51 crossing the rear side from the front side at the upper end face of the fixed wing portion 50 Respectively. The width may be formed to have the same width in both lateral directions around the reference circle 51, or the width may gradually decrease as the width increases in both lateral directions. Therefore, this form not only brings about an aesthetic effect but also can be easily mounted on the floor surface by using the shape of the fixed blade 50 when the mounting device is mounted on the floor without putting it on the fingers.

When the fixed wing portion 50 is viewed from the front side, the fixed wing portion 50 is protruded so as to be rounded with respect to the reference circle 51. That is, it extends along the curved surface of the finger holder 30, and is located at the top in a convex circular shape. However, if the fixed wing portion 50 is viewed from the side, it has the same shape as the fins of a shark, which will be described in detail later with reference to FIG.

Further, if the thickness of the fixed blade portion 50 is set to about 8 to 10 mm, it is also possible to mount it between a majority of the automobile air outlet grilles through the fixed blade portion 50. Referring to Fig. 2, when viewed from the front side of the fixed blade portion 50, with reference to the side edge portion which is the highest point with respect to the side surface and the tip portion which is the highest point with respect to the upper surface side, A first rounding part 57 extending from one side to a side end of the second rounding part 50 to a fourth curved line and a second rounding part 58 extending from the side end part to a pointed- And the other side is constituted by symmetrically symmetrical to the above-described one.

Here, looking at the tip end portion and the second rounding portion 58, it can be seen that the side end portion protrudes somewhat as if an arrowhead is seen. Therefore, if this point is utilized, the side end portion of the automobile air outlet grille can be hooked to the ventilation hole.

Since the interval between the grilles of a typical automobile air outlet grill is about 1 cm, if the width of the thickest portion of the fixed blade portion 50 is set to about 8 to 10 mm, it is possible to insert and mount the grille between the grilles of the automobile air outlet.

4 is an enlarged view showing the fixed blade in detail.

Referring to FIG. 4, the fixed blade 50 will be described in more detail. The fixed blade 50 includes a first extending part 52 formed to be convexly extended from the front side to a first curved line and a second extending part 52 extending from the first extending part 52 A third extended portion 53 formed to extend from the second extended portion 53 up to the second reference point to a tip portion (third reference point) located at the highest position in the fixed wing portion 50, An extension part 54, and a fourth extension part 56 which is concavely extended from the tip part to a fourth reference point rearwardly in a third curved line.

The first reference point, the second reference point, the third reference point, and the fourth reference point are arbitrary points at which the curvature is changed when the stationary vane unit 50 is viewed from the side.

However, the first, second and third curves may be the same, but it is preferable that the first curve, the second curve and the third curve have different curves. In the case of the third curved line, the first extended portion 56 having the third curved line corresponds to a curved line in which the first seating portion 31 of the finger fixing portion 30 described above is recessed and formed to be rounded concavely. A continuous joint portion may be formed in the same curvature up to the first seat portion 31 as an extension.

In addition, the eccentric portion 55 can be covered with the third reference point and the tip end portion. The eccentric part 55 includes an elastic body for covering the outside of the tip end part or a weight having a predetermined weight. When the eccentric part 55 is mounted on the bottom surface without putting the fingers on the finger as described above, It plays a role of weight, and it can also prevent slipping by additionally applying appropriate friction force.

In addition, the tip end portion may have an acupressure effect. When the finger is put on the finger rest portion 30, the leading end portion of the fixed wing portion 50 is located above the finger interstice portion. Therefore, the eccentric part 55 attached to the tip end portion presses the area between the fingers, thereby providing a shiatsu effect. Particularly, in the case of such a chiropractic function, even if a finger located at the finger mount 30 is moved a little, it is possible to apply various positions of the area between the fingers.

5 is a perspective view showing a hinge structure.

5, a hinge 20 is applied between the receiving unit 10 and the finger mounting unit 30, so that the receiving unit 10 and the finger mounting unit 30 can be hinged to each other via the hinge 20 So that they are rotatably coupled to each other. In other words, the male hinge 20 is formed on the receiving portion 10, the female hinge 20 is formed on the finger mounting portion 30, or the female hinge 20 is mounted on the receiving portion 10 to the finger mounting portion 30 And the male hinge 20 is formed to be rotatable with respect to each other. It is most preferable that the male hinge 20 is provided on the receiving portion 10 and the female hinge 20 is formed on the finger mounting portion 30 in consideration of the rotation angle and the stability of the rotation when rotating. In addition, the male hinge 20 may be additionally provided with a bar that can assist the rotation for more rigid and effective hinge engagement. If such a bar is inserted into the female hinge 20 together with the male hinge 20, a more solid rotation can be formed.

In other words, the application of the hinge 20 is for the rotation of the finger rest 30, so that the finger rest 30 is normally stored side by side with the rest 10, The finger mount 30 is rotated in the height direction so that the finger mount 30 can be used as a cradle. However, when the portable electronic device is used as a cradle, the portable electronic device must be supported in a specific direction or shape. Therefore, a stopper structure may be formed on the hinge 20 or a coupling surface of the hinge 20 may be formed of a material having a frictional force. .

Also, in the case of using the eccentric portion 55 as described above, even when the eccentric portion 55 is used as a force applicator, a slight force is applied to the hinge 20 while the finger is being held.

In addition, a body part may be additionally formed on the lower portion of the finger mount 30 to protrude so as to be rounded along the lower portion thereof in order to apply such a hinge structure. Such a body part is for protecting the finger rest 30 according to the rotation of the hinge 20. The finger rest 30 is provided directly on the receiving part 10 because the finger rest 30 is protruded to be convexly rounded, As shown in FIG.

6 is a use state diagram of a portable electronic device mounting apparatus.

Fig. 6 (a) shows a state of a mounting device attached to a case of a portable electronic device, and Fig. 6 (b) shows a state in which the mounting device is held between fingers.

As described above, the mounting device can be attached to the portable electronic device or the portable electronic device case, and the receiving portion 10 becomes an object to be attached. The portable electronic device mounting device attached to the first mounting portion 31 seats between the fingers and the fingers on the first mounting portion 31, thereby increasing the grip feeling so that the portable electronic device is not easily detached from the hand when the portable electronic device is gripped. Also, as can be seen from the shape, it can be installed as a pedestal on the ground as it is attached to the portable electronic device or the case of the portable electronic device to support the portable electronic device or the portable electronic device case, May be coupled to the portable electronic device or the portable electronic device case.

7 is an exploded perspective view of the finger rest.

Referring to FIG. 7, the following will be described. And a hook space (33) penetrating the central portion so that at least one finger can be inserted into the finger mount (30). In other words, in the shape of the above-described finger mount 30, a hook space 33 penetrating the central portion is formed, thereby forming a triangular or square ring shape. Also, the receiving portion 10 may be formed of a disk-like plate material, and the finger receiving portion 30 and the hinge 20 may be rotatable with each other. In this case, the finger mount 30 may be extended to a lower end so that the hinge 20 can be easily attached.

According to this shape, the user can insert a finger into the hooking space 33 or hang a member such as a string, a rope, or another ring so that the user can perform more various mounting operations.

Further, it is possible to further deform the receiving portion 10 to rotate in a three-dimensional range instead of a simple unidirectional rotation, which will be described in more detail with reference to FIG. 8 which will be described later.

Fig. 8 is a perspective view of the portable electronic device mounting device receiving portion fitting structure.

Referring to FIG. 8, the receiving portion 10 may have a plate-like structure of a coupling structure of the first receiving portion 11 and the second receiving portion 12. The bonding of the first and second receiving portions 11 and 12 can be chemically bonded (bond, silicone, adhesive, tape, etc.), but the shape of the first and second receiving portions 11 and 12 can be deformed, Lt; RTI ID = 0.0 > a < / RTI > In the case of chemical attachment, it can be combined with a structure in which a flat surface is attached with a bond, silicone, adhesive, tape or the like to the support part, or in the case of a physical connection, a fitting structure or a rail structure is applied.

A rail 13 is formed at a predetermined depth on the binding surface of the first receiving portion 11 and a shape corresponding to the rail 13 is formed on the lower end surface of the second receiving portion 12. For example, A puller 14 protruding at a predetermined height is formed. It is a matter of course that a variety of known shapes such as a rectangular shape or a saw tooth shape can be applied to the shapes of the rails 13 and the puller 14 that are embedded and protruded. The fuller 14 is coupled to the rail 13 by being engaged with the rail 13. Through such a structure, only the receiving portion having the first receiving portion 11 formed is normally attached to the portable electronic device or the portable electronic device case It is possible to mount the fusing unit 10 on which the puller 14 is formed by fitting the fusing unit. In addition, a stronger coupling force can be provided if the one side of the rail 13 of the first receiving portion 11 is closed by fitting and disassembling in the same direction so that the puller 14 can not be easily disengaged.

However, in the above-described structure, it is difficult for the puller 14 to be fitted and fixed only in a predetermined direction to perform mounting at various angles. In this case, it is possible to apply a rotational coupling structure to the laminated structure of the receiving portion 10.

Fig. 9 is a perspective view of the rotation coupling structure of the portable electronic device mounting device receiving portion.

Referring to FIG. 9, the following will be described. First, between the first and second receiving portions 11 and 12, a rotating ring engaging portion, which is a rotatable engaging portion, is formed. The rotation ring coupling portion is a coupling between the main ring 15 and the rotation portion 16, and the main ring 15 is fitted to the rotation portion 16 so that the rotation ring can be rotated.

More specifically, the main ring 15 is formed in an annular shape and is made of an aluminum material that does not easily change from an external force. In consideration of metal interference in wireless charging, It is needless to say that various known materials can be used. The main ring 15 is formed on the other side of the first receiving portion 11 as an attachment medium such as an adhesive, an adhesive pad or an adhesive tape and is attached to any one of the portable electronic device and the portable electronic device case, A structure in which a coupling terminal is formed and physically attached to a case of a portable electronic device having a corresponding coupling terminal, and a structure in which a main ring 15 is formed together when the portable electronic device case is manufactured .

The first bearing portion 11 may be formed in the same shape as the main ring 15 or may be formed in a circular shape including the main ring 15 and the first bearing portion 11 and the inner space thereof A main ring 15, a first receiving portion 11, and an inner space, and may include a peripheral space. At this time, the central portion, which is the inner space of the main ring 15, is exposed to the outside, and if a printed matter such as a mark is placed on the corresponding portion, advertisement effect can be aimed. In addition, You can see the effect of guiding you to find.

The main ring 15 has a shape corresponding to that of the main ring 15 and covers the upper end of the main ring 15 or a set with the pivot portion 16 which is engaged with the lower end of the main ring 15. The pivot portion 16 is rotatable by engaging with the main ring 15. The turning portion 16 is also formed of the same material as the main ring 15 and may be formed on the second receiving portion 12 or may be formed as a ring-shaped separate member like the main ring 15 and then attached.

Accordingly, when the double rotation coupling structure is applied, only the conventional hinge 20 can be moved in one direction only, but it can be rotated through the rotational coupling between the rotation portion 16 and the main ring 15, It is possible to mount it on the ground.

As described above, the configuration and operation of the portable electronic device mounting apparatus having the finger mounting unit according to the present invention are described in the above description and drawings. However, the present invention is not limited to the above- And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
