Description

AN IMPROVED PORTABLE ELECTRONIC DEVICE

FIELD OF INVENTION

[0001] The present invention relates to an improved portable electronic device. More specifically, the present invention is related to a multi-purpose slide-able base enabled to function as a protective cover and an input device for the portable electronic devices.

BACKGROUND

[0002] The portable electronic devices (PEDs) are generally lightweight devices powered by electricity or battery. The portable electronic devices are typically capable of communication and data processing applications; such devices mainly include notebook and tablet computers (e.g., the Apple® iPad™), Personal Digital Assistants (PDAs), and smart phones etc. These portable electronic devices (PEDs) are in trend widely because of their computing power and multi-applicability in almost every field of human life for e.g. education, business, medical, aviation, entertainment etc.

[0003] There are many types of portable electronic devices (PEDs) that differ on the basis of many factors such as technology, size, application and their portability. For the ease of consumers, the portable electronic devices (PEDs) are improving day by day. The portable electronic devices of prior art are versed with many useful features such as playing audio and videos, inter-operability, intra- operability, data computing, data transfer media such as Bluetooth and many more.

[0004] There are many limitations of the conventional portable electronic devices for e.g. in laptop cum table computer and in other similar devices both keyboard and table computer (screen) are vulnerable to mechanical damages and dust. The keyboards are of bulky size having keypad in which the keys are almost flat. In desktop computers, it is difficult to keep screen above keyboard (downside) and in tablets with attachable keyboards, it is also a very chance of losing the keyboard. Further, it is difficult to separate table from laptop (keyboard) hence they cannot solely use as tablet.

[0005] There are few prior art references which provide solution to the above mentioned problems as follows:

[0006] Reference 1 is a US patent application no. 20140262876 Al titled "combined cover, keyboard and stand for tablet computer with reversible connection for keyboard and reading configuration". The prior art reference discloses a protective cover with a housing and a latch mechanism in which the latch is slide-ably coupled to the housing and hingeably coupled to a back portion of the housing such that the latch is configured to rotate, via the hinge coupling, from a closed position to an open position.

[0007] Reference 2 is a US patent no. 5,375,076 titled "Combined notepad and notebook computer". The prior art reference discloses a combined notebook and notepad computer having housing, a removable keyboard and a pivotable stand connected to said main housing.

[0008] Reference 3 is a US patent no. 8,369,074 titled "Keyboard device for use with tablet personal computer". The prior art reference discloses a keyboard device for use with a tablet personal computer includes a base body and an upper cover. The base body includes a handle and plural keys. The handle is integrally formed with the base body. The upper cover has a receptacle for accommodating the tablet personal computer.

[0009] Reference 4 is a US patent no. 7,206, 198 titled "Portable computer with handle-cum- stand". The prior art reference discloses a portable computer includes a main body and a handle. The handle can be used to serve as both a carrying handle for the computer and as a stand for holding the computer in a convenient position for use on a desk.

[0010] However, despite of the advancement offered by the features disclosed the prior art, a need remains for further improvements, particularly with regard to manageability and lock-ability of portable electronic devices and the input media. The portable electronic devices are also susceptible to damage due to their portable nature and because they are often carried or used in locations where extreme temperatures, dust or other particles, vibration or physical impact is likely. Another disadvantage, due to existing attachable keyboards and covers, the thickness of tablet or other portable electronic device increases as they covers both the side (screen as well as back) and hence become inconvenient to carry. Also, mostly portable electronic devices require separate arrangement for stand to stabilize it and it in turn creates a restriction to use on multi -positions. Further, in existing portable electronic devices attached with keyboard, screen cannot keep horizontal without detaching it from keyboard.

[0011] The existing portable electronic devices are arranged to swivel over the keyboard or a like input media for viewing from different angles. However, their rotating neck or arms are not rigid hence venerable to mechanical jerk.

[0012] In view of aforementioned, it is required to provide a portable electronic device that can overcome the limitations and disadvantages of the prior arts.
