Description

    FIELD OF THE INVENTION
  • [0001]
    The present invention generally relates to a protective bag, and more particularly to a protective bag for a portable electronic device.
  • DESCRIPTION OF THE RELATED ART
  • [0002]
    With the development of technology, various portable electronic devices, such as a multimedia player (MP3, MP4 and so on), a cell phone, a personal digital assistant (PDA), a hand-held game console, an electronic book (E-book), a tablet personal computer (tablet PC), a netbook, a notebook and so on, have become an integral part of modern life to many people. To compare with the traditional desk PC, a main advantage of the portable electronic device is easy to get carried. Therefore, in recent years, we can see people operating the portable electronic devices anytime and anywhere.
  • [0003]
    In the above mentioned portable electronic devices, some are the hand-held game consoles, which comprise two bodies and these two bodies can be folded/unfolded relative to each other. One body has a pure screen and the other has another screen and a plurality of buttons. Also, for the netbooks and the notebooks, a screen and a keyboard are configured on two bodies, which can be folded/unfolded relative to each other. Accordingly, the screen can be supported by the other body to stand with an adjustable inclination, and thus the user can hold the device or put on a table to watch videos or operate.
  • [0004]
    Many users may use a protective sheath or a protective bag for the convenience of protecting and carrying the portable electronic device. Currently, there are two main design types about the commercial protective sheaths and the protective bags. In the first design type, one side edge of the sheath or the protective bag can be opened, and users must unzip a zipper or unlock a fastener to open the side edge to take the portable electronic device out of the protective sheath or bag to use, and that is inconvenient.
  • [0005]
    In contrast, in the second design type, three adjacent side edges of the protective sheath or bag are sealed with a zipper, the user can unzip the zipper to directly unfold the sheath or bag, and then the user may put the portable electronic device on an inner surface of the protective sheath or bag to use directly. Besides, there may has two elastic tapes, bands or belts disposed on the inner surface for banding or hanging two corners of the screen body of the portable electronic device, so as to avoid the protective sheath or bag directly dumping backward to collide with other things after being unfolded.
  • [0006]
    However, the screen body of the portable electronic device is getting thinner, and thus the screen body is not as easily to be banded tightly as usual. Hence, the elastic tapes, bands or belts may loosely hang on the screen body and thus the sight is affected when the screen body is flipped upward. Further, the elastic tapes, bands or belts may fall from the corners of the screen body when the screen body is flipped upward to a large angle, for example over 120 degrees. Moreover, in recent years, a gap between two bodies of the portable electronic device is designed to be narrower and narrower, and thus the elastic tapes. bands or belts are improper to band the screen body.

Referring to FIG. 1, FIG. 2 and FIG. 3 first, the protective bag 100 of the present invention may use to contain a portable electronic device 200, wherein the portable electronic device 200 has a first body 210 and a second body 220 pivoted to the first body 210.
  • [0029]
    In the present embodiment, the portable electronic device 200 as illustrated herein is a notebook. Besides, the part of the notebook disposed with the keyboard is the first body 210 as illustrated in this embodiment, which is capable of being carried on a carrying surface 300, while the part of the notebook disposed with the screen is the second body 220 as illustrated in the present embodiment, which is capable of being folded relative to the first body 210 for covering the first body 210, or unfolded relative to the first body 210 for standing on the carrying surface 300. Further, in other non-illustrated embodiments, the portable electronic devices may also be practiced to a netbook, a hand-held game console or the other kinds of portable electronic devices having two bodies capable of being folded or unfolded relative to each other.
  • [0030]
    The protective bag 100 comprises a first covering plate 110, a second covering plate 120 and at least a connecting component 130 connected between a first side edge 112 of the first covering plate 110 and a second side edge 122 of the second covering plate 120. In addition, the first covering plate 110 may further has a first fastener 114 disposed opposite to the first side edge 112, while the second covering plate 120 may further has a second fastener 124 disposed opposite to the second side edge 122. In this embodiment, the protective bag 100 comprises only one connecting component 130 connected between a middle portion of the first side edge 112 and a middle portion of the second side edge 122. However, in other non-illustrated embodiments, the protective bag may comprise two connecting components connected between where adjacent to two ends of the first side edge and where adjacent to two ends of the second side edge, or a plurality of connecting components arranged averagely between the first side edge and the second side edge.
  • [0031]
    Moreover, as illustrate in FIG. 3, the first covering plate 110 and the second covering plate 120 may be folded relative to each other about the connecting component 130 formed as a shaft, so as to form a containing space 102 for containing the portable electronic device 200. Herein, the first covering plate 110 covers a bottom surface 212 of the first body 210, the second covering plate 120 covers a rear surface 222 of the second body 220, and the first fastener 114 and the second fastener 124 are capable of fastening together, so as to hold the portable electronic device 200 between the first covering plate 110 and the second covering plate 120. Thereafter, as illustrated in FIG. 4, the bottom surface 212 may be carried on the carrying surface 300 via the first covering plate 110, and the second covering plate 120 may stand on the carrying surface 300 with a support provided by the connecting component 130 or lean against the rear surface 222 after users unlock the first fastener 114 and the second fastener 124 and then unfolded the second body 220 relative to the first body 210.
  • [0032]
    In detail, in the present embodiment, the first fastener 114 and the second fastener 124 may be formed from a zipper set. Furthermore, each of the first covering plate 110 and the second covering plate 120 may be a plastic plate, the connecting component 130 may be a U-shaped plastic flat spring, and the first covering plate 110, the second covering plate 120 and the component 130 may be integrally formed by injection molding or thermoforming. However, in the other embodiments, the first covering plate 110, the second covering plate 120 and the component 130 may be connected by a manner such as fastening, attaching with adhesive, screwing, riveting and so on. As illustrated in FIG. 4, when a user is unfolding the second body 220 relative to the first body 210 after the first fastener 114 and the second fastener 124 are unlock (i.e. after the zipper set is unzipped), the second covering plate 120 is unfolded relative to the first covering plate 110 about the connecting component 130 by the second body 220, and thus the connecting component 130 is elastically deformed. At this time, the second covering plate 120 leans against the rear surface 22 with an elastic restoring force provided by the connecting component 130, so as to stand on the carrying surface 300. Therefore, the second covering plate 120 is not only sightlier in use, but also not likely to dump backward to collide with other things after being unfolded.
  • [0033]
    Furthermore, in the other non-illustrated embodiments, each of the first covering plate and the second covering plate may be made from a metal material or any other solid material capable of letting the connecting component deform elastically and being rotated about the connecting component with the elastic restoring force provided by the connecting component. Besides, the connecting component can further be a metal flat spring, a torsion spring, a spiral spring, any other elastic component with the same functions or a combination thereof. In addition, a range of motion of an angle formed between the first covering plate 110 and the second covering plate 120 is ranged from 0 degree to 150 degrees, so as to avoid forming an elastic fatigue of the elastic component due to an unfolded angle between the first covering plate 110 and the second covering plate 120 is too lager.
  • [0034]
    It should be noted that a free angle of the elastic component may be preset as larger than 0 degree, for example 15 degrees as illustrate in FIG. 5. In such instance, the second covering plate 120 is unfolded automatically relative to the first covering plate 110 as long as the first fastener 114 and the second fastener 124 are unlocked, and thus it is convenient for users not only taking the portable electronic device 200 out of the protective bag 100 but also unfolding the first body 210 relative to the second body 220. As a result, the protective bag 100 is more convenient in use.
  • [0035]
    Moreover, referring to FIG. 6 and FIG. 7, the connecting component 130 may also be a shaft with a close fit structure commonly used in current notebooks. Hence, as illustrate in FIG. 6, an included angle between the first covering plate 110 and the second covering plate 120 may be maintained with a friction provided by the close fit structure of the connecting component 130. In another word, the second covering plate 120 may stand on the carrying surface 300 with a support provided by the connecting component 130.
  • [0036]
    FIG. 8 illustrates a perspective view of a shaft with a close fit structure connecting the first covering plate and the second covering plate according to an embodiment of the present invention, and FIG. 9 illustrates a cross-sectional view of the shaft with the close fit structure as illustrated in FIG. 8. Referring to FIG. 8 and FIG. 9 together, in a preferred embodiment, the connecting component 130 can comprise at least a shaft 132, a first metal sheet 134, and a second metal sheet 136. As illustrated in FIG. 8, in the present embodiment, the connecting component 130 comprises two shafts 132, and each of the shafts 132 is a combination of a nut N and a bolt B, so as to form the close fit structure, wherein a tightness provided by the shafts 132 may be adjusted by tightening or releasing the bolts B with the nuts N. Besides, each of the shafts 132 may provide a torque ranged from 3.5 to 5.5 kgf-cm. In addition, a range of motion of an angle formed between the first metal sheet 134 and the second metal sheet 136 may be ranged from 0 degree to 345 degrees.
  • [0037]
    The first metal sheet 134 is fastened to the first covering plate 110, the second metal sheet 136 is fastened to the second covering plate 120, and both of the shafts 132 are pivoted between a side edge of the first metal sheet 134 distant from the first covering plate 110 and a side edge of the second metal sheet 136 distant from the second covering plate 120. The detail structures of the second metal sheet 136 and the connection between the second covering plate 120 and the second metal sheet 136 are described herein after, while the detail structures of the first metal sheet 134 and the connection between the first covering plate 110 and the first metal sheet 134 are omitted herein due to similar to that of the second metal sheet 136.
  • [0038]
    In detail, referring to FIG. 9, the second covering plate 120 in the present embodiment may further have an inner surface 126, an outer surface 128, a first dent D1 formed on the inner surface 126, a second dent D2 formed on the outer surface 128 and a slit S extending from the inner surface 126 to the outer surface 128. Besides, the second metal sheet 136 in the present embodiment comprises a first folded plate P1, a second folded plate P2, a main plate P3, and a pivoting portion PP, wherein the pivoting portion PP comprises a connecting plate P4 and two circular folded plates P5 (as shown in FIG. 8). The first folded plate P1 is embedded within the second dent D2. The second folded plate P2 is connected between the first folded plate P1 and the main plate P3 and embedded within the slit S, i.e. the second folded plate P2 passes through the second covering plate 120. Part of the main plate P3 is embedded within the first dent D1, and the other part of the main plate P3 is extended outside of the second covering plate 120. The connecting plate P4 is connected between a side edge of the main plate P3 opposite to the second folded plate P2 and the two circular folded plates P5.
  • [0039]
    Besides, each of the shafts 132 is fitted into one of the circular folded plates P5 of the first metal sheet 134 and a corresponding one of the circular folded plates P5 of the second metal sheet 136. Thus, the first covering plate 110 and the second covering plate 120 may be folded and unfolded relative to each other by the connecting component 130. It should be noted that since the tightness provided by the shaft 132 may be adjusted by tightening the bolt B with the nut N, the second covering plate 120 may stand on the carrying surface 300 with a support provided by the connecting component 130. Furthermore, as illustrated in FIG. 8, in the present preferred embodiment, the connecting plate P4 (illustrated in FIG. 9) of the second metal sheet 136 may have a gap G formed between the circular folded plates P5 (illustrated in FIG. 9), and both of the circular folded plates P5 (illustrated in FIG. 9) of the first metal sheet 134 are located within the gap G, and vice versa. In addition, as illustrated in FIG. 9, each of the first covering plate 110 and the second covering plate 120 may further comprise a plurality of enforcing rods R protruding from the bottom surfaces of the first dent D1 and the second dent D2 and passing through the first folded plate P1 and the main plate P3, so as to tightly fasten the first folded plate P1 and the main plate P3 on the first covering plate 110 and the second covering plate 120 respectively.
  • [0040]
    However, in the other non-illustrated embodiments, the structure of at least one of the first metal sheet and the second metal sheet as illustrated in FIG. 8 and FIG. 9 for fastening to the first covering plate and/or the second covering plate may further be replaced by a manner such as melt bonding, fastening, attaching with adhesive, screwing, riveting or a combination thereof. Furthermore, the connecting component may further be practiced by a gear wheel structure, a structure screwed with nuts or other pivot structures commonly used in current notebooks as well. Besides, the first fastener may further be a crochet belt of a Velcro®, a male snap button of a snap button set, a permanent magnet, a hook or a pin, while the second fastener may further be a velour belt of the Velcro®, a female snap button of the snap button set, a ferromagnetic material, a locking aperture or a inserting aperture, and vice versa. Alternatively, the first fastener and the second fastener may be permanent magnets with opposed polarities as well.
  • [0041]
    Referring to FIG. 4 again, it should be noted that the connecting component 130 and the first covering plate 110 and the second covering plate 120 made from solid materials may damage the bottom surface 212 and the rear surface 222 of the portable electronic device 200 in use, and thus the protective bag 100 is recommend to comprise an inner material layer 140. The inner material layer 140 covers the inner surfaces 126 of the first covering plate 110, the second covering plate 120 and the connecting component 130 (for simplifying the figure, the inner surfaces of the first covering plate 110 and the connecting component 130 are not illustrated in FIG. 4) for separating the portable electronic device 200 from the first covering plate 110, the second covering plate 120 and the connecting component 130, and is made from fiber cloth or other materials not likely to damage surfaces of the portable electronic device. Besides, the protective bag 100 may further comprise a lining cushioning material layer 150 disposed between the inner material layer 140 and the inner surfaces 126.
