It is sectional drawing which shows the back attachment part of the covered cover.

As shown in Figure 1 to 9, the smartphone protective case 1 according to an embodiment of the present invention includes a cover 10 and the housing 20.

The housing 20 includes a substantially concave recess in which a smartphone is housed, and is made of polycarbonate (PC) to have good durability. When the smartphone is housed in the housing 20, the front face of the smartphone with the touch panel is exposed forward through the recess and the back face of the smartphone is in contact with the recess bottom of the housing 20. [ A hole (s) is formed on the back side of the housing 20 to expose the camera and / or the flashlight on the back side of the smartphone. The housing 20 may also be configured to expose various devices located at the top, bottom and / or sides of the smartphone, such as an antenna, earphone jack, charging port, volume control, and / On the upper, lower, and / or both sides of the frame.

The cover 10 includes a rear cover portion 12 and a front cover portion 14 which are connected to each other in parallel by a flexible connection portion 13. The rear cover part 12 and the front cover part 14 are spaced apart from each other by a predetermined distance except for a region where the connection part 13 is present. The rear cover part 12 is always located on the rear side of the housing 20 in which the smartphone is accommodated, and the front cover part 14 is in the first state shown in FIGS. 1 to 5B, that is, the cover is closed. In the state, it is positioned to cover the front of the smartphone accommodated in the housing 20.

The connection portion 13 has flexibility so as to allow the rotation of the front cover portion 14 with respect to the rear cover portion 12. The rotation of the front cover portion 14 allows the connection of the front cover portion 14, The front of the smartphone that has been screened by can be exposed. The cover open state, which can expose the front face of the smartphone, can be defined by various rotation angles and positions of the front cover part 14. [ For convenience of description, the front cover portion 14 is rotated to form 180 degrees with respect to the rear cover portion 12, that is, the front cover portion 14 and the rear cover portion 12 are the same. A state located on the plane is defined as a second state, that is, a cover fully open state (shown in FIGS. 6 and 7).

The rear cover part 12 includes a back surface attachment part 122 attached to the back surface of the housing 20 and a back surface unattached part 124 that is not attached to the back surface of the housing 20. At this time, the backside unattached portion 124 is connected to the connecting portion 13 in an intermediate region including one side edge of the backside cover portion 12. [ The rear surface attachment portion 122 is formed so as to enclose the other end, the upper end, and the lower end of the rear surface attachment portion 124 except for one end in a form. The rear cover part 12 is connected to the connection part 13 at one side edge of the backside unattached part 124. Therefore, the connection portion 13 connects the backside unattached portion 122 and the front side cover portion 14 among the backside cover portions 12.

As will be described in detail below, the front cover part 14 is entirely made of an austenitic stainless steel sheet, more preferably STS 304 thin plate as a reinforcing core material, while the connecting part 13 has a stiffness, And is made of only a leather outer shell and a lining fabric without a reinforcing core so as to have flexibility allowing the rotation of the front cover portion 14 with respect to the cover portion 12. [ The front cover 14 can smoothly rotate within a range of about 360 degrees through the deformation of the connection portion 13 to selectively cover the front surface of the smartphone housed in the housing 20. [ The rear cover portion 12 includes a hinge line 123 parallel to the connection portion 13 at a boundary between the rear surface attachment portion 122 and the rear surface attachment portion 124.

The back non-attaching portion 124 is rotated by the hinge line 123 to form a predetermined first angle (a °) with the back surface attaching portion 122 while the back non-attaching portion 124 is engaged with the connecting portion 13, the cover 10 forms a tripod that tilts the smartphone housed in the housing when the front cover 14 is at a second predetermined angle b ° with respect to the front cover 14, It is defined as a smartphone stand state, that is, a third state. In the process of making the stand state, when the smartphone is housed in the housing, due to the weight of the smartphone, the angle between the back-side non-attachment portion 124 and the back- ).

The backside unattached portion 124 has a stiffness including an austenitic stainless steel thin plate, more preferably a STS 304 thin plate as a reinforcing core, like the front cover portion 14. The rear unbonded portion 124 and the frontal cover portion 14 which form two sides of the three sides of the tripod have rigidity by an austenitic stainless steel thin plate applied as a reinforcing core member, (122) is made of a lining fabric, a leather outer shell, and an EVA (Ethylene Vinyl Acetate) cushion layer without a reinforcing core, but is attached to the rigid housing (20).

The front cover part 14 is connected to the connection part 13 at one corner, and has a first bending rib 142 bent at an opposite corner thereof to be bent substantially vertically. The first bending ribs 142 are formed by vertically bending a portion extending from the other edge of the front cover portion 14 to a substantially rectangular shape. It is needless to say that the first bending rib 142 includes a part of the austenitic stainless steel sheet included in the front cover part 14. [ The first bending rib 142 is in contact with the first side 21 of the housing 20 in a first state in which the front cover 14 covers the front of the smartphone, ) Without any distortion for a long period of time. The first bending rib 142 is disposed on the second side 22 of the housing 20 in which the smartphone is housed in a stand state in which the cover 10 stands on a tripod shape of the smartphone, And functions to support the tilted state. At this time, the first side surface 21 of the housing 20 and the second side surface 22 of the housing 20 are opposed to each other.

In addition, the rear non-attachment portion 124 of the rear cover portion 12 is provided with a second bending rib 1242 on one side of the corner, which is erected with one side of the hole formed in the connecting portion 3 as an axis. The two bent ribs 1242 are formed by bending the portions protruding from the rear non-attachment portion 124 having rigidity by the austenitic steel thin plate and have rigidity similarly to the rear non-attachment portion 124. The second bending ribs 1242 are formed on the side surface of the housing 12 in a general state in which the rear unbonded portion 1242 is in contact with the back surface of the housing 20 regardless of exposure or occlusion of the front surface of the smartphone. So that the housing 12 is maintained in a fixed position.

The front cover portion 14 includes an austenitic stainless steel thin plate having a thickness of approximately 0.3 mm in almost all the areas except for the portion where the view window 143 is provided. Further, the backside unattached portion 124 includes an austenitic stainless steel thin plate in the lamination cross section over the entire area. On the other hand, the connecting portion 13 is made of a flexible material without an austenitic stainless steel sheet so as to allow the rotation of the front cover portion 14 with respect to the rear cover portion 12. [ The back surface attachment portion 122 may be made of a flexible material so that it can be easily attached to the housing 20, for example, by an adhesive. Since the austenitic stainless steel thin plate applied to the cover 10 is almost non-magnetic, the influence of the electromagnetic waves or electromagnetic waves can be minimized. In addition, the austenitic stainless steel sheet is excellent in elastic restoring property and contributes greatly to keeping the cover 10 in its original shape without permanent deformation.

The view window 143 is made of transparent plastic, more specifically, a transparent member formed of a transparent carbonic resin material. The user can confirm the caller identification, the call reception and the rejection, and the device status while the front cover part 14 covers the front touch panel of the smart phone through the view window 143. [

Referring to FIG. 10, the laminated cross section of the front cover portion 14 includes a lining fabric H as a lower layer and a synthetic leather outer shell L including, for example, polyurethane (PU) as the uppermost layer. And an austenitic stainless steel thin plate (I) laminated on the lining fabric (H) and an EVA (I) laminated on the austenitic stainless steel thin plate (I) are arranged between the lining fabric (H) The cushion layer J is interposed. On the EVA layer (J), a leather outer cover (L) is laminated. The EVA cushion layer J provides excellent cushioning and excellent gripping property to the front cover part 14 and the austenitic stainless steel thin plate I, more specifically the STS 304 thin plate I, 14). In addition, the STS 304 thin plate (I) is formed to have a thickness of about 0.3 mm, and has elastic recovery properties against twisting, and has almost no thermal expansion or heat shrinkage. The characteristics of this STS 304 thin sheet I contribute greatly to keeping the original shape of the smartphone case 1 intact over time. In addition, the STS 304 thin sheet I minimizes the influence of electrons or electromagnetic waves, as described above.

On the other hand, the front cover part 14 is provided with an opening through which the lining fabric H, the STS 304 thin plate I, the EVA cushion layer J and the synthetic leather sheath L are sequentially passed through to form the view window 143 . The opening is formed in the end surface of the EVA cushion layer J with a size larger than that of the first opening O1 located over the end face of the lining fabric H and the STS 304 thin plate I, A second opening O2 forming a step between the openings O1 and O2; And a third opening (O3) formed so as to include an inclined surface inclined inwardly in a cross section of the synthetic leather shell (L).

A transparent member (K) formed of a carbonic resin material is inserted into the opening to form the view window (143). The transparent member K includes a first portion k1 sandwiched by the first opening O1 and a second portion k2 protruding outwardly in a size larger than the first portion O1 and sandwiched by the second opening O2. (k2). The outer protruding portion of the second portion is embedded between the leather outer shell L and the STS 304 thin plate I below the third opening O3 in contact with the end surface of the EVA cushion layer J. [ The edges of the transparent member K are not covered with the outer skin L of the leather so as to be exposed to the outside and thus there is no fear that a clearance is formed between the transparent member K and the opening. The leather covering (L) includes an inclined surface that is inclined toward the transparent member (K) to reduce a sharp step.

Referring to FIG. 11, the laminated cross section of the back non-attachment part 124 includes a leather outer shell L including a lining fabric H as a lower layer and a polyurethane as a top layer. An austenitic stainless steel thin plate (I) is interposed between the lining fabric (H) and the leather outer cover (L). . Unlike the front cover portion 14, the EVA cushion layer is omitted. The omission of the EVA cushion layer in the rear unbonded portion 14 helps smooth connection with the connecting portion 13, helps smooth rotation of the rear unbonded portion 14, and reduces the cost increase due to unnecessary material increase.

Referring to FIG. 12, the laminated cross section of the connection part 13 includes a leather jacket L including a lining fabric H as a lower layer and a polyurethane as a top layer. It is preferable that the leather covering L is directly laminated on the lining cloth H but it is also conceivable to add a layer having flexibility between the leather covering L and the lining cloth H,

Referring to FIG. 13, the laminated cross section of the back attachment part 122 includes a lining fabric H as a lower layer and a synthetic leather outer shell L including polyurethane (PU) as the uppermost layer. An EVA cushion layer (J) is interposed between the lining fabric (H) and the leather outer cover (L). The EVA cushion layer J may be directly laminated on the liner fabric H and the austenitic stainless steel sheet I may be omitted for easy attachment to the housing of the rear surface attachment portion 122 It is good.

Both the back cover portion 12 and the front cover portion 14 are provided with the leather covering L on the side where the smartphone protection case is placed so that the protection can be prevented even if the smartphone is placed on a slippery side . At this time, the EVA cushion layer J, which can be provided right under the leather outer cover L, plays a role of improving the grip feeling and cushion feeling of the smartphone protective case, and also helps the leather outer cover L to suppress the jamming of the smartphone hobo case .
