However, the present invention is not limited to the embodiments described below, but may be implemented in various other forms, and these embodiments are not intended to be exhaustive or to limit the invention to the precise form disclosed, Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

FIG. 1 is a perspective view showing a protective case for a portable device of the present invention, and FIG. 2 is a side sectional view showing a protective case for a portable device of the present invention.

FIG. 3 is a plan view of a protection case for a portable device according to the present invention, and FIG. 4 is a state diagram illustrating a state in which the protection case for a portable device of the present invention is installed in a portable device.

1 to 4, a protective case for a portable device according to the present invention includes a frame 100 and a gripping member 200.

First, the frame 100 is formed so as to cover the rim of the portable device 10 such as a smart phone, but is stretchable and compact in a small size.

Here, the frame 100 may be enlarged in size by elastic deformation, and is tightly coupled to the periphery of the portable device 10 by elastic restoring force when the frame 100 is engaged with the edge of the portable device 10.

The frame 100 for this purpose has a frame shape in which a hollow 110 is formed so as to pass through in the front and back so that the portable device 10 can be inserted into the center.

When the frame 100 is coupled to the edge of the portable device 10, the inner circumferential surface 120 of the frame 100 may be coupled to the edge of the portable device 10 in close contact with each other.

The front and rear widths of the frame 100 may have a width that can cover a rim portion of the portable device 10 of the corresponding model.

For example, the width of the frame 100 may be equal to or greater than the width of the portable device 10.

The frame 100 may be made of synthetic rubber or silicone rubber having a hardness of 30 to 80 degrees so as to be able to expand to a predetermined size.

Here, the synthetic rubber may be a natural rubber (NR), an acrylonitrile-butadiene rubber (NBR), an ethylene propylene rubber (EPM / EPDM), a butadiene rubber (BR), an isoprene rubber (IR), or a polychloroprene rubber have.

And, silicon can use HTV (High Temperature Vulcanization) or rubber compound series.

At this time, since the frame 100 has a hardness of 30 to 80 degrees, it can be expanded to a size of 10 to 300% in a reduced state.

That is, since the frame 100 has a lower hardness than that of a case for a general portable device 10, it can be expanded to a size of the portable device of the corresponding model.

In addition, the frame 100 may be closely attached to the edge of the portable device 10 while reducing the thickness thereof.

In addition, a connection hole 130 and an operation hole 140 may be formed in the upper, lower, left, and right directions of the frame 100, respectively.

The connection hole 130 is formed to penetrate the inside and the outside of the frame 100 so that the speaker, connection terminal (earphone connector, charger connection portion, etc.) 11 of the portable device 100 can be exposed to the outside as shown in FIG. .

At this time, the connection terminal 11 of the portable device 10 positioned in the same position as the connection hole 130 may be exposed to the outside through the connection hole 130.

The connection hole 130 may be formed in various shapes depending on the shape of the connection terminal 11 of the portable device 10.

The connection hole 130 may be formed by calculating the position of the connection terminal 130 such that the connection terminal 130 is positioned at the same position as the connection terminal when the size of the frame 100 is expanded.

The manipulation tool 140 can be inserted or positioned in the same manner as the manipulation button 12 of the portable device 10 as shown in Fig.

Here, the manipulation tool 140 may be protruded to the outside of the frame 100 so that the user can perform a pressing operation or the like.

Alternatively, the manipulation tool 140 may be formed to penetrate the inside and the outside of the frame 100, or may be displayed by a separate groove, protrusion, pattern, or the like without projecting the manipulation tool 140 out of the frame 100 .

When the size of the frame 100 is enlarged, the manipulation tool 140 may be formed so as to be positioned in the same position as the manipulation button.

For example, when the frame 100 is used in a portable device 10 such as a smart phone, the frame 100 may be formed into a rectangular or rectangular frame having a length in the vertical direction.

In addition, the frame 100 may have different thicknesses for each part so that the frame 100 is closely attached to the edge of the portable device 10 with the same pressure.

For example, when the portable device 10 is a smart phone formed longer in the vertical direction, since the adhesion force between the left and right sides may be different from the close contact force between the upper and lower sides, the thickness of the frame 100 in the left- have.

Of course, the thickness and shape of the frame 100 can be selectively applied depending on the shape and characteristics of the portable device 10. [

The connection hole 130 is located at a portion of the connection terminal 11 disposed at the edge of the portable device 10 and may be formed to be penetrated to the outside so that the connection terminal 11 is exposed to the outside.

The manipulation tool 140 is located at a portion of the manipulation button 12 disposed on the rim of the portable device 10 and may be formed to be pierced or protruded to the outside so that the manipulation button 12 can be manipulated.

Since the frame 100 is closely adhered to the edge of the portable device 10 with a small thickness, it is possible to provide a feeling that the mobile phone case is not used without increasing the volume of the portable device.

In addition, the frame 100 can show the outer shape of the portable device 10 as it is, and is excellent in appearance and can prevent the portable device 10 from being easily detached from the hand because it does not slide on the hand.

In addition, since the frame 100 has adhesive force, it can improve the adhesion with the portable device 100 and can be used semi-permanently because the elastic restoring force is excellent. In the elastic restoring, the volume is reduced to a large extent, And has ease.

The grip member 200 protrudes along the inner circumferential surface 120 of the frame 100 to protect the edge of the portable device 100 and prevent the portable device 100 from being detached from the outside.

Here, the gripping members 200 are positioned at the front and rear of the frame 100, respectively, and engage front and rear edge portions of the portable device 100 in front and rear directions, respectively.

At this time, the gripping member 200 may extend in a shape corresponding to the inner circumferential surface of the frame 100, but the gripping member 200 may be locally formed on the inner circumferential surface of the frame 100.

The gripping members 200 may have a shape in which the width of the gripping members 200 gradually decreases toward the center position of the frame 100.

At this time, the grip member 200 may be horizontally formed so that one end of the grip member 200 exposed in the front-rear direction of the frame 100 is flush with the front and rear surfaces of the frame 100.

2, the grip member 200 may be formed with a sloped surface 210 on one side of the center of the frame 100. As shown in FIG.

The inclined surface 210 is in close contact with the front and rear edge portions of the portable device 10 in the front-rear direction of the frame 100.

The gripping member 200 may be integrally formed with the frame 100 and may be formed of the same material as the frame 100.

That is, since the gripping member 200 is made of synthetic rubber or silicone material, the gripping member 200 can be elastically expanded together with the frame 100 to be in close contact with the front and rear edge portions of the portable device 10.

Stiffeners 300 for reinforcing strength may be inserted into the inner circumferential surface 120 of the frame 100, respectively.

The stiffener 300 may be inserted into each side of the frame 100 while being separated from each other and one end adjacent to the frame 100 may be spaced apart when the frame 100 is expanded in size.

Here, the stiffener 300 may be inserted into the thickness of the frame 100 in a partly divided state.

For example, as shown in FIG. 5, the stiffener 300 may be divided at four corner portions formed by the frame 100.

In this state, when the frame 100 is expanded, the size of the divided portion of the stiffener 300 may be enlarged.

Alternatively, the stiffener 300 may be inserted into two or three sides of the four sides formed by the frame 100 as shown in FIG.

In this case, the remaining two sides of the frame 100 or the divided parts of one side may be enlarged and the size may be enlarged.

The divided portions of the stiffener 300 can be selectively applied according to the shape and characteristics of the portable device 10.

The length and thickness of the stiffener 300 may vary depending on the thickness of the frame 100 and the characteristics of the portable device 10.

The reinforcing member 300 may be made of any one of metal, carbon, and plastic. However, the reinforcing member 300 may selectively use various materials as needed.

Since the stiffener 300 has a higher strength than the frame 100, it can be prevented from being transmitted to the portable device 10 through the frame 100 when an impact of a predetermined force or more is applied from the outside.

As a result, since the present invention can be elastically deformed into a shape corresponding to the outer shape of the portable device 10 using synthetic rubber or silicone material, The feeling of not using the cellular phone case can be given without greatly increasing the volume of the cellular phone 10.

In addition, since the adhesive strength is improved, adhesion with the portable device 10 can be improved, and the appearance of the portable device can be displayed without being easily peeled from the portable device 10.

In addition, since synthetic rubber or silicone material is used, it is possible to prevent the portable device from being easily released from the hand because it does not slip in the hand.

In addition, since the elastic restoring force is excellent, it can be used semi-permanently, and it can be easily stored and carried since the volume of the elastic restoration is sharply reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that various changes and modifications may be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the embodiments described, but should be determined by the scope of the appended claims, and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the invention is indicated by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the present invention should be construed as being included within the scope of the present invention.
