BACKGROUND OF THE INVENTIONRecently, 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 competitiveness. As can be seen in the evolution of computers from desktops to laptops to palmtops and tablets, the reduction in weight and size of hardware has made electronic devices highly portable. In addition, intuitive operation has been a major trend in software engineering. The core spirit of today's industrial development is to employ all applicable hardware and software means to the design and production of electronic devices with which users can interact more conveniently and more intuitively.
Among the aforementioned electronic devices, tablet personal computers, or tablet PCs, feature a good balance between portability and performance and, thanks to their mode of operation that suits people's reading habits, have stepped from the PC market into the market of electronic readers. Hence, tablet PCs have lately been a major product category for a good number of companies and the first choice among consumers wishing to buy the foregoing electronic devices. Now that the main features of tablet PCs are portability and flexibility in operation, most users would carry their tablet PCs with them and are more likely to operate the tablet PCs on the move than they would other electronic devices. Because of that, tablet PCs require more protection.
Currently, the market is supplied with a variety of protective elements for use with tablet PCs. According to the part to be directly protected, these protective elements can be generally divided into the following: protectors for the entire tablet, such as film wraps and protective cases; screen protectors, such as protective adhesive films and screen covers; and protective covers for the back cover of a tablet PC. Protective elements like film wraps and protective adhesive films are chiefly designed to protect tablet PCs from being scratched by a pointed object or by friction and therefore provide little protection against external impact, which nevertheless may easily damage a tablet PC if the part being hit is the screen. In consideration of this, tablet PC users tend to choose a protective element that can protect the screen. Some users prefer a screen cover to a protective case, which covers the entire tablet, as the major protective element, with a view to keeping their tablet PCs easy-to-use and esthetically pleasing. In coping with such preference, screen covers are typically designed to be readily detachable and adaptive to the features of tablet PCs, thus not only allowing a tablet PC to be gracefully used in a stationary state, but also allowing a screen cover to be easily removed from the tablet PC with which it is used and be put aside, so as to restore the structural simplicity and compactness of the tablet PC. However, a screen cover alone cannot protect the back cover of a tablet PC against collision or friction while the tablet PC is being carried around. Further, as screen covers are mostly configured for easy detachment, a screen cover may separate from the tablet PC to be protected should the tablet PC be operated with big hand movements. If, in that case, the user grasps the screen cover only, the tablet PC is very likely to drop to the ground and be damaged. To prevent such accidents, the user must pay extra attention when operating the tablet PC, which is against the aforesaid core spirit of enabling easy and intuitive use of tablet PCs.
In a nutshell, although it is generally desired to use tablet PCs under different circumstances, so far there are no easy and practical solutions that can simultaneously satisfy the different needs to use tablet PCs under various conditions. The issue to be addressed by the present invention is to provide a simple and practical device that serves the purpose.
BRIEF SUMMARY OF THE INVENTIONIn 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.
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.
Another object of 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 protective cover is applicable to a tablet PC and a screen cover of the tablet PC. The tablet PC includes a front cover and a back cover and is provided with a connecting portion adjacent to a lateral edge of the tablet PC where the front cover and the back cover are connected. The screen cover includes a pivot shaft, two bearing seats, a turning rod, and a covering portion. The pivot shaft of the screen cover and the connecting portion can be connected by engagement or attraction therebetween. The two ends of the pivot shaft are respectively and pivotally connected in the bearing seats, and so are the two ends of the turning rod. The turning rod is spaced from the pivot shaft by a gap and has an axis parallel to that of the pivot shaft. The covering portion has one end covering the surface of the turning rod and is turnable about the turning rod so as 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, which is made of a resilient material, has one side 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. Also, the cover body is formed with an opening corresponding in position to each bearing seat of the screen cover. The at least one gripping portion is provided at a periphery of the cover body that is adjacent to the receiving space. More particularly, each gripping portion has a hook-shaped configured formed by the periphery of the cover body extending toward the receiving space. Additionally, 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 is inserted in between the pivot shaft and the turning rod from outside the pivot shaft. This ensures that the pivot shaft will not come off the connecting portion while the screen cover is being turned. When the bearing seats are pivoted simultaneously about the pivot shaft, the turning rod is moved about the pivot shaft outside the fastening portion.
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.
The structure as well as a preferred mode of use, further objects, and advantages of the present invention will be best understood by referring to the following detailed description of some illustrative embodiments in conjunction with the accompanying drawings, in which:
