Abstract

A laptop computer is designed to be used lying on the user's lap. Because there is an obvious need to make the computer smaller, it is becoming increasingly less comfortable to use the computer on the lap. The problem is that humans have to change body positions frequently, but a small computer can lie on the lap essentially in one position. In particular, it requires the user to keep his legs in the same position all the time. Thus, there is a need for an improvement that would allow the user of a laptop computer to change his legs position while using the computer. A second problem addressed here is that when a laptop is used on the lap, there is no flat space to hold a sheet of paper or a booklet that the user may need to look at.

Improvement to the ease of use of a laptop computer

    A laptop computer is designed to be used lying on the user's lap. Because there is an obvious need to make the computer smaller, it is becoming increasingly less comfortable to use the computer on the lap. The problem is that humans have to change body positions frequently, but a small computer can lie on the lap essentially in one position. In particular, it requires the user to keep his legs in the same position all the time. Thus, there is a need for an improvement that would allow the user of a laptop computer to change his legs position while using the computer. A second problem addressed here is that when a laptop is used on the lap, there is no flat space to hold a sheet of paper or a booklet that the user may need to look at.

    The main idea of the invention is to equip the laptop computer with an extendible base. With a wider and deeper base, the user can move the legs, holding them in different positions under the computer, use more flat space for holding paper documents. Let's refer the dimensions of the laptop as W (width) and D (depth). An extendible base can be implemented in several ways:

Two hard sheets (for example 1mm of aluminium), each of dimensions W/2 by D can be installed at the bottom of the laptop so that they slide out to the two sides of the computer. If, for example, a sheet slides out 50% of its size, then the width of the base is increased by W/4 on each side, thus increasing the width by W/2 or 50%. On a typical laptop with W=12" this amounts t...
