Description

FIELD OF THE INVENTION

This invention is related to a back protective cover for a tablet device.

BACKGROUND ART

One of the accessories for a tablet device placed on the market by Apple Inc. is a touch-screen cover which can be attached to and detached from the tablet device by means of a built-in magnet and can protect a touch screen of the tablet device. Further, the touch-screen cover functions as a keyboard stand when folded, and thus, is very convenient.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

The above-mentioned touch-screen cover is very convenient as noted above, however, the inventor of the present invention has found, while using it, that the touch-screen cover sometimes comes off the tablet device when grasping only the touch-screen cover and lifting it. In order to prevent the problem of coming off of the touch-screen cover, making the magnet more powerful or fixing the touch-screen cover to the tablet device with an adhesive or the like might be effective. However, since one of the attractive features of the touch-screen cover is that it can be easily detached when it is not needed, making the touch-screen cover difficult to come off by such methods will detract the attractive feature of the touch-screen cover.

Such a problem arises not only in the combination of the tablet device made by Apple Inc. and the above-mentioned touch-screen cover for this tablet device but also in a combination of a tablet device other than the tablet device made by Apple Inc. and a touch-screen cover attachable to and detachable from this tablet device.

The present invention is made in view of such a circumstance and provides a back protective cover for a tablet device which can prevent a touch-screen cover from coming off the tablet device.

Means to Solve the Problem

According to the present invention, a back protective cover which covers a back of a tablet device is provided, the back protective cover comprising a separation preventing section which is configured to cover an attaching/detaching section of a touch-screen cover of a detachable type, the touch-screen cover covering a touch screen of the tablet device, so as to prevent separation between the touch-screen cover and the tablet device.

While a back protective cover is sometimes attached to a back of a tablet device in order to prevent a casing of the tablet device from being scratched, the inventor of the present invention has found that a problem of coming off of a touch-screen cover can be prevented by using a back protective cover that is provided with a separation preventing section shaped to cover an attaching/detaching section used in attaching the touch-screen cover to the tablet device, and has completed the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a state in which a back protective cover according to an embodiment of the present invention is attached to a tablet device to which a touch-screen cover has been attached, where (a) is a plan view, (b) is a back view and (c) is a side view.

FIG. 2 is a sectional view taken along line A-A in FIG. 1 (a).

FIG. 3 is an enlarged view of region B in FIG. 2.

EMBODIMENTS FOR CARRYING OUT THE INVENTION

Hereafter an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The following embodiment is only for illustrative purposes and the scope of the present invention is not limited to the one illustrated by the following embodiment.

As shown in FIGS. 1 to 3, a touch-screen cover (e.g., “iPad Smart Cover”) 3 is provided on a touch-screen side of a tablet device (e.g., “iPad2”) 1. The touch-screen cover 3 is of a detachable type and comprises a main section 3a configured to cover a touch screen (not shown) of the tablet device 1 and an attaching/detaching section 3b configured to allow the touch-screen cover 3 to be detachably attached to the tablet device 1. The attaching/detaching section 3b has a built-in magnet and the attaching/detaching section 3b is fixed to a side surface of the tablet device 1 by means of magnetic force. The main section 3a is rotatable with respect to the attaching/detaching section 3b at a hinge portion 3c, so that the main section 3a can be opened and closed with the attaching/detaching section 3b fixed to the tablet device 1.

A back protective cover 5 is provided on a back side of the tablet device 1. The back protective cover 5 is of a detachable type and comprises a main section Sa configured to cover a back surface (and side surfaces) of the tablet device 1 and a separation preventing section Sb which extends from the main section Sa. The main section Sa can be fixed to the tablet device 1. The separation preventing section Sb is bent so as to surround the attaching/detaching section 3b and prevents the attaching/detaching section 3b from being separated from the tablet device 1. Therefore, by using the back protective cover S of this embodiment, the touch-screen cover 3 never comes off the tablet device 1 even if only the touch-screen cover 3 is lifted, and thus, the problem of falling of the tablet device 1 or the like can be prevented. Further, in a case of using a back protective cover without the separation preventing section Sb, a surrounding area of the attaching/detaching section 3b is exposed so that the tablet device 1 may be scratched in the area, however, by using the back protective cover S of this embodiment, which has the separation preventing section Sb, the surrounding area of the attaching/detaching section 3b is also covered by the back protective cover S, and thereby the problem of scratching can be prevented.

The back protective cover S is preferably made of polycarbonate. With this material the back protective cover S can be transparent, so that a logo and the like provided on the back surface of the tablet device 1 can be visually recognized in a state where the back protective cover S is attached.
