Protective cover capable of fastening pivot shaft of screen cover of tablet PC

Abstract

The present invention is to provide a protective cover capable of fastening a pivot shaft of a screen cover of a tablet PC, wherein the pivot shaft is connectable to a connecting portion between front and back covers of the tablet PC, so that the screen cover can be turned about the pivot shaft to cover the front cover. The protective cover includes a cover body having one side concavely provided with a receiving space for receiving and protecting the back cover, at least one gripping portion having a hook-shaped configuration formed by the periphery of the cover body for hooking to the peripheral edge of the tablet PC after the back cover is received in the receiving space, and a fastening portion formed by an extension of the periphery of the cover body for fastening the pivot shaft while the screen cover is being turned about the pivot shaft.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a protective cover, more particularly to a protective cover capable of fastening a pivot shaft of a screen cover of a tablet PC, wherein the protective cover includes a cover body having one side concavely provided with a receiving space for receiving and protecting a back cover of the tablet PC, and a fastening portion formed by an extension of the periphery of the cover body for fastening the pivot shaft while the screen cover is being turned about the pivot shaft to cover a front cover of the tablet PC.BACKGROUND OF THE INVENTION[0002]Recently, with the significant advancements in hardware and software technologies and the continuous improvement of ergonomics, the research and development of electronic devices are no longer focused only on such performance indicators as operation speed. The provision of better user-device interaction is nowadays an even more important issue in the development of industrial competitivene...

Benefits of technology

[0006]In view of the aforementioned shortcomings of the conventional protective elements for use with tablet PCs, the inventor of the present invention incorporated years of practical experience into extensive research and development and finally succeeded in creating a protective cover that can fasten a pivot shaft of a screen cover of a tablet PC. With the assistance of the present invention, one can operate a tablet PC conveniently and intuitively while holding the tablet PC or its screen cover at any desired position.

[0007]It is an object of the present invention to provide a protective cover capable of fastening a pivot shaft of a screen cover of a tablet PC. The protective cover is applicable to a tablet PC, wherein the tablet PC includes a front cover and a back cover and is provided with a connecting portion. The connecting portion is adjacent to a lateral edge of the tablet PC where the front cover and the back cover are connected. A screen cover has a pivot shaft that is connectable to the connecting portion by engagement or attraction therebetween, so that the screen cover can be turned about the pivot shaft to cover or not cover a screen on the front cover. The protective cover includes a cover body, at least one gripping portion, and a fastening portion. The cover body is made of a resilient material such as polycarbonate (PC), polyvinyl chloride (PVC), or polyethylene terephthalate (PET). One side of the cover body is concavely provided with a receiving space for receiving the back cover and thereby protecting the back cover from being scratched or indented by an external force which may otherwise rub against or hit the back cover. The cover body is formed with an aperture corresponding in position to each part of the tablet PC that is configured for interaction with the outside, such as the parts where a loudspeaker, a camera lens, various pushbuttons, and various peripheral connectors are respectively provided. The at least one gripping portion is provided at a periphery of the cover body that is adjacent to the receiving space. More specifically, each gripping portion has a hook-shaped configuration formed by the periphery of the cover body extending toward the receiving space. In addition, each gripping portion corresponds in shape to the peripheral edge of the tablet PC and can hook to the peripheral edge of the tablet PC after the back cover is received in the receiving space, thus connecting the cover body and the back cover as a single piece. The fastening portion is provided on the cover body, corresponds in position to the connecting portion, and is formed by an extension of the periphery of the cover body. Once the cover body and the back cover are connected as a single piece, the fastening portion fastens the pivot shaft of the screen cover, ensuring that the pivot shaft will not come off the connecting portion while the screen cover is being turned.

[0009]Hence, even if the user takes hold only of the screen cover while using the tablet PC and thus causes the tablet PC to swing, the pivot shaft is prevented from coming off the connecting portion. Consequently, the tablet PC is kept form damage which may otherwise occur if the tablet PC is dropped to the ground. In other words, with the assistance of the protective cover, the user may hold the tablet PC or the screen cover at any desired position when using the tablet PC. Furthermore, due to its easy installation and removal, the protective cover can be temporarily detached, even along with the screen cover, if the tablet PC is used in a stationary state, e.g., when used in a bedroom or study of the user's home. This allows the tablet PC to be operated in its most compact form. When it is desired to carry the tablet PC around or use the tablet PC during commute or in a place where people come and go, the tablet PC, the screen cover, and the protective cover can be readily put together to provide enhanced protection for the tablet PC. It is also feasible to connect the protective cover directly to the tablet PC in the absence of the screen cover. Therefore, the protective cover can be used in different combinations and has more flexibility in use than a protective case designed to cover the entire tablet PC. Moreover, the protective cover may come with different external designs so that users can show their personal styles with the protective covers they choose.
