Universal and lockable tablet personal computer protective case

Abstract

A universal and lockable tablet PC protective case serves to accommodate an external tablet PC and has a housing, four support pads and a lock assembly. The housing has an upper frame and a lower cover pivotally mounted on the upper frame. The support pads are detachably mounted on four corners of the lower cover. A thickness of each support pad plus a thickness of the tablet PC matches a height of a chamber inside the housing. Each support pad has a curved surface formed in a top of the support pad. The lock assembly locks the upper frame and the lower cover. The support pads are replaceable to provide different types of curved surfaces to accommodate tablet PCs having different shapes. Additionally, as the upper frame is securely locked on the lower cover, it is unnecessary to replace the protective case for insecure locking therebetween.

AI Technical Summary

Benefits of technology

[0007]An objective of the present invention is to provide a universal and lockable tablet PC protective case accommodating tablet PCs having different shapes and solving the loosely locking problem after being used for a long period of time.

[0012]The protective case provides the housing with the height greater than the thickness of the tablet PC and has a support pad mounted on each of the four corners of the inner bottom of the lower cover of the housing. The curved surface formed in the top of each support pad abuts against a corresponding corner of the rear panel of the tablet PC so that the tablet PC can be firmly accommodated inside the housing. Accordingly, users just need to replace the support pads having different thickness and curved surface to accommodate the tablet PC having different size and shape without having to replace the entire protective case. As the upper frame and the lower cover are securely locked to each other by the lock assembly, the upper frame does not easily come off the lower cover after the protective case is used for a long period of time. Accordingly, the protective case does not have to be replaced for sake of accommodation of tablet PC of a new generation or due to reduced locking tightness of the protective case, thereby making the protective case cost effective.

Problems solved by technology

Thus, the second-generation tablet PC fails to be accommodated inside the protective case compatible with the first-generation tablet PC.

After new tablet PC is rolled out and old tablet PC is obsolete, the protective case dedicated to the old tablet PC can no longer be used and ends up as waste of resources.

However, the locking means of the upper frame and the lower cover is not stable enough.

After being operated for a while, the upper frame and the lower cover are oftentimes untightly locked, and there is a chance that a tablet PC inside the protective case is damaged for inadvertently sliding out of the protective case.
