## Background
INCORPORATION BY REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of priority to U.S. Provisional Application No. 62/140,842, filed Mar. 31, 2015. The above application is hereby incorporated herein by reference in its entirety and is to be considered a part of this specification.


FIELD
The present teachings relate to a cover for a computer, and more particularly, to a protective cover including a detachable keyboard for a tablet computer.
BACKGROUND
The present teachings are predicated upon providing an improved protective cover for a tablet computer. While promoting portability, some tablet computers can be difficult to grasp and hold, which can lead to damage especially during handling and transporting. Accordingly, protective covers were introduced to protect the tablet computer from damage. For example, a folio-style protective cover can be folded into a closed position to protect at least one side of the tablet computer; however, other parts of the tablet computer can be left exposed and can be susceptible to damage during handling or transporting.
Most tablet computers offer a virtual on-screen keyboard for data input; however, typing on a virtual keyboard can be difficult and cumbersome, especially during prolonged periods. While various external keyboards are available for tablet computers, external keyboards may negate the portability advantage of a tablet computer.
Some protective covers have attempted to integrate a keyboard with a protective cover; however, disadvantages still exist. For example, some integrated keyboards are not separable from the protective cover or the tablet computer, which can undesirably limit versatility of the tablet computer. While some protective covers attempted to provide a detachable integrated keyboard, detaching and subsequently attaching some integrated keyboards can be cumbersome. Moreover, certain protective covers that include integrated keyboards that only allow the integrated keyboard to be used in a single, flat configuration or placed flat on a support surface, which can make typing uncomfortable and cumbersome, especially when used for prolonged periods.
In view of the above, it may be desirable to provide an improved protective cover for a tablet computer. It may be desirable to provide a protective cover for a tablet computer that can protect all surfaces and edges of the tablet computer. It may be attractive to provide a protective cover with an integrated keyboard that can be quickly and easily detached and attached to the protective cover, tablet computer, or both. It may be attractive to have a protective cover with an integrated, detachable keyboard for a tablet computer that can provide for the tablet computer to be used in a variety of configurations. It may be advantageous to provide a protective cover and integrated keyboard for a tablet computer where the integrated keyboard can be angularly positioned on a support surface. It would be desirable to provide an improved cover for a tablet computer that is lightweight, can be mass-produced relatively inexpensively, that has a minimal number of parts, and that is easy to operate.

It is envisioned that the one or more coupling features may also include one or more quick connect features, hook and loop fasteners, detents, etc.
The protective cover and the tablet computer can be used in one or more configurations. For example, the tablet computer can be used in one or more tablet-typing configurations where the front cover, the tablet computer, or both are angularly oriented relative to a support surface. For example, in one or more tablet-typing configurations, the front cover can form an angle with the support surface on the order of about 5 degrees or more, 10 degrees or more, 15 degrees or more, or about 25 degrees or more. In the one or more tablet-typing configurations, the front cover can form an angle with the support surface on the order of about 40 degrees or less, about 30 degrees or less, about 20 degrees or less, about 10 degrees or less, or even about 5 degrees or less. In the one or more tablet-typing configurations, the tablet computer, the back cover, or both can form an angle with a plane extending generally perpendicular to the support surface on the order of about 0 degrees or more, about 5 degrees or more, about 15 degrees or more, about 20 degrees or more, about 30 degrees or more, about 45 degrees or more, or about 60 or more, or even about 70 degrees or more. In the one or more tablet-typing configurations, stand can form an angle with a plane extending generally perpendicular to the support surface on the order of about 0 degrees or more, about 1 degrees or more, or even about 5 degrees or more.
In the tablet-storage configuration, the input side of the front cover can be folded over the front surface of screen of the tablet computer. In the tablet-storage configuration, the front surface or screen of the tablet can be at least partially covered by the front cover, but is preferably fully covered by the front cover.
In the one or more tablet-viewing configurations, the front cover can be removed from the back cover, the tablet computer, or both. In the one or more tablet-viewing configurations, an angle of the tablet computer relative to a support surface or an axis extending generally perpendicular to the support surface can be adjusted any desired angle by moving or adjusting the tablet computer, the stand, or both via the stand hinges. For example, in the one or more tablet-viewing configurations, an angle of the tablet computer relative to an axis extending generally perpendicular to the support surface can be on the order of about 0 degrees or more, about 10 degrees or more, about 20 degrees or more, about 45 degrees or more, about 60 degrees or more, or even 80 degrees or more. In fact, the angle of the tablet computer relative to the axis extending generally perpendicular to the support surface in the one or more tablet-viewing configurations can be any angle providing that the stand, the stand hinges, or both can maintain the weight of the tablet computer. Accordingly, in the one or more tablet-viewing configurations, an angle between the stand and the tablet computer can be any desired angle.
