DESCRIPTION OF EMBODIMENTS
The disclosure provides a foldable cover 100, adapted to protect or support a portable electronic device 10. FIG. 1A is a top view illustrating a foldable cover according to a first embodiment of the disclosure. The foldable cover 100 of the embodiment comprises a supporting unit 110, a fixing unit 120, and a connection member 130. The connection member 130 is connected between the supporting unit 110 and the fixing unit 120.
In the embodiment, the connection member 130 is a flexible element. However, in other embodiments, the connection member 130 can be a magnetic element or a locking element. The type of the connection member 130 is not limited thereto.
The supporting unit 110 comprises a plurality of first separations 112, a convergent part 114, and a plurality of first slab-shaped parts 116. Each of the first separations 112 is connected to the convergent part 114, and respectively partitions two adjacent first slab-shaped parts 116. The first slab-shaped parts 116 can be connected to each other through various connecting methods. In the embodiment, two adjacent first slab-shaped parts 116 respectively include a fixing part 116a. Two fixing parts 116a are fixed through a magnetic attraction, so that the supporting unit 110 forms a three dimensional structure so as to support the portable electronic device 10.
As shown in FIG. 1A, the shape of the supporting unit 110 is a rectangle, with two long sides and two short sides. The shapes of the first slab-shaped parts 116 are triangles. In the embodiment, the convergent part 114 is located on a perpendicular bisector of the long side of the supporting unit 110. One of the first separations 112 is simultaneously located on the perpendicular bisector. Of course, the shape of the supporting unit 110 and the first slab-shaped parts 116, and the location of the convergent part 114 are not limited thereto.
The fixing unit 120 is used to place and fix the portable electronic device 10. The portable electronic device 10 can be locked to the edge of the fixing unit 120. In an embodiment, the edge of the fixing unit 120 is flexible. The portable electronic device 10 can be fixed to or separated from the fixing unit 120 by simply bending the portion that locks the fixing unit 120 and the portable electronic device 10. Herein, the other fixing methods of the embodiment are omitted. One skilled in the art can use other fixing methods without departing from the scope of the disclosure.
FIG. 1B is a schematic side view of the foldable cover of FIG. 1A covering a portable electronic device. As shown in FIG. 1B, when the foldable cover 100 of the embodiment protects the portable electronic device 10, the portable electronic device 10 is placed in the fixing unit 120, and the supporting unit 110 covers the portable electronic device 10. At this point, each first slab-shaped part 116 is located on the same surface.
FIG. 1C is a three dimensional schematic view of the foldable cover of FIG. 1A that is folded. FIG. 1D to FIG. 1F are three dimensional schematic views of the foldable cover of FIG. 1A deforming to support the portable electronic device. As shown in FIG. 1C, the first separation 112 is bent along two adjacent fixing parts 116a on the supporting unit 110, so that the two adjacent fixing parts 116a lean against each other.
After the two fixing parts 116a are combined, the supporting unit 110 forms a three dimensional structure (as shown in FIG. 1D), so as to support the portable electronic device 10. In the embodiment, the three dimensional structure that is formed after the supporting unit 110 of the foldable cover 100 is deformed is a pyramid.
As shown in FIG. 1D to FIG. 1F, the supporting unit 110 can form a pyramid to support the portable electronic device 10 so that the user can place the portable electronic device 10 vertically or horizontally onto a table. Since the pyramid that the supporting unit 110 forms after being deformed is not an equilateral pyramid, thus, when different sides of the pyramid with different shapes are placed on the table, the portable electronic device 10 of the fixing unit 120 will prop against the pyramid at different angles.
In the embodiment, two fixing parts 116a are magnetic. When two fixing parts 116a of two first slab-shaped parts 116 are leaned against each other, the two fixing parts 116a will be fixed to each other through attraction, to maintain the pyramid shape. Of course, the fixing parts 116a can also be locked or adhered together, and the method for fixing the fixing parts 116a is not limited thereto.
In addition, since the fixing unit 120 is connected to the supporting unit 110 through the connection member 130, when the supporting unit 110 forms a three dimensional structure, the fixing unit 120 can lean against the surface of the three dimensional structure. Thus, regardless of whether the foldable cover 100 is used to protect or support the portable electronic device 10, the portable electronic device 10 does not need to be removed from the fixing unit 120.
When the foldable cover 100 is used to support the portable electronic device 10, the connection member 130 is bent at different portions to adjust the angle of the portable electronic device (FIG. 1D to FIG. 1E) or the position between the three dimensional structure and the portable electronic device 10 (FIG. 1F), so that the three dimensional structure is closer to the center of the portable electronic device 10.
FIG. 2 is a top view illustrating a foldable cover according to a second embodiment of the disclosure. The only difference between the embodiment of FIG. 2 and the embodiment of FIG. 1 is the type of the fixing unit. As seen in FIG. 2, the fixing unit 220 of the foldable cover 200 of the embodiment comprises an inner surface 222 and an outer surface 224.
The inner surface 222 comprises an inner edge 222a, and three outer edges 222b. The inner edge 222a of the inner surface 222 close to the supporting unit 210 is not connected to the outer surface 224, and the other three outer edges 222b are flexibly connected to the outer surface 224. The shape of the inner surface 222 is a hollow rectangle, and the material of the inner surface 222 is a soft material, such as leather.
When the portable electronic device 10 is put in or taken out of the fixing unit 220, the inner edge 222a of the inner surface 222 of the fixing unit 220 is pulled away from the outer surface 224 of the fixing unit 220. The inner surface 222 will slightly deform so that the portable electronic device 10 can be put in or taken out of the fixing unit 220. When the portable electronic device 10 is located in the fixing unit 220, the portable electronic device 10 is clamped between the inner surface 222 and the outer surface 224 of the fixing unit 220 so that it will not fall out.
FIG. 3A is a top view illustrating a foldable cover according to a third embodiment of the disclosure. As seen in FIG. 3A, the difference between the foldable cover 300 of the embodiment and the foldable cover 100 of FIG. 1A is that the supporting unit 310 of the embodiment further comprises two second slab-shaped parts 317 and a pair of second separations 318. An end of each of the two second separations 318 are connected to each other. The two separations 318 separate parts of the supporting unit 310, so as to divide out two second slab-shaped parts 317.
FIG. 3B is a three dimensional schematic view of the foldable cover of FIG. 3A deforming to support the portable electronic device. As seen in FIG. 3B, the bending along the second separations 318 cause the two slab-shaped parts 317 to be located on different surfaces. This way, the center of gravity of the three dimensional structure that is formed by the supporting unit 310 is moved, so as to increase the stability of the three dimensional structure, or to adjust the angle of the portable electronic device 10. Of course, the supporting unit 310 can also include a plurality of pairs of second separations 318, so as to satisfy different user requirements.
FIG. 4 is a top view illustrating a foldable cover according to a fourth embodiment of the disclosure. As seen in FIG. 4, the supporting unit 310 of the foldable cover 400 of the embodiment provides another type of distribution of the first separations 412, the convergent part 414, and the first slab-shaped parts 416.
In the embodiment, the shape of the supporting unit 410 is a rectangle, with two long sides and two short sides. The convergent part 414 is located on a perpendicular bisector of the short side of the supporting unit 110. One of the first separations 412 is simultaneously located on the perpendicular bisector. It can be seen from the embodiment and the embodiment of FIG. 1A that the alignment and length of the first separations 412, 112 and the shape of the first slab-shaped parts 416, 116, are different based on the different positions of the convergent parts 414, 114.
FIG. 5 is a top view illustrating a foldable cover according to a fifth embodiment of the disclosure. As seen in FIG. 5, the supporting unit 510 of the foldable cover 500 of the embodiment comprises a plurality of first separations 512, a convergent part 514, a plurality of first slab-shaped parts 516, two second slab-shaped parts 517, and a pair of second separations 518.
Each of the first separations 512 is connected to the convergent part 514, and partitions the first slab-shaped parts 516. An end of the two second separations 518 respectively connect to each other, and two second slab-shaped parts 517 are partitioned by two second separations 518. Bending along the second separations 518 can cause two sides of the two slab-shaped parts 517 to be located on different surfaces. This way, the center of gravity of the three dimensional structure that is formed by the supporting unit 510 is moved, so as to increase the stability of the three dimensional structure.
In addition, the fixing unit of the foldable cover 500 of the embodiment further comprises a first locking assembly 540. The first locking assembly 540 is flexibly connected to the supporting unit 510. The portable electronic device 10 comprises a second locking assembly 11, wherein the first locking assembly 540 is used to lock to the second locking assembly 11. When using the foldable cover 500 of the embodiment to protect the portable electronic device 10, the supporting unit 510 of the embodiment covers a face of the portable electronic device 10 by rotating about the first locking assembly 540 as the rotation axis. For example, the supporting unit 510 can cover the screen of the portable electronic device 10, so as to lower the chance of scratching the screen.
The portable electronic device 10 usually comprises a transmission interface 12, so as to transmit data or power. When the using the foldable cover 500 of the embodiment to support the portable electronic device 10, in order to use the portable electronic device 10 at the same time, and perform data transmission or power charging, the locking assembly 540 of the embodiment comprises a first through hole 542.
The supporting unit 510 further comprises a second through hole 519. The first through hole 542 connects through the second through hole 519. When the foldable cover 500 is connected to the portable electronic device 10, the transmission interface 12 is exposed by the first through hole and the second through hole, so that external apparatuses can pass through the first through hole 542 and the second through hole 519 to connect to the transmission interface 12.
