PAD STRUCTURE
A pad structure is disposed on the bottom of a casing of an electronic device, which includes a skidproof piece and a slide piece. The skidproof piece is used for securing and supporting the electronic device on a plane. When the electronic device is at an oblique angle opposite to the plane, and drags the skidproof piece away from the plane, the slide piece contacts with the plane, and the electronic device is enabled to move on the plane by the slide piece.

This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 097135708 filed in Taiwan, R.O.C. on Sep. 17, 2008 the entire contents of which are hereby incorporated by reference.
BACKGROUND OF THE INVENTION1. Field of Invention
The present invention relates to a pad structure, and more particularly a pad structure disposed on the bottom of a casing of an electronic device.
2. Related Art
For a housing of a common electronic device such as a computer, a host, and a screen, pads are generally disposed at periphery of the casing bottom, which can assist in the firm arrangement of the electronic device on a plane such as a desktop and a floor. The pads also support the electronic device to a certain height, thus avoiding the casing of the electronic device from directly contacting with the desktop or the floor to influence the performance of the electronic device due to the heat generated during the operation.
For example, in a laptop computer, the pad disposed at the bottom of the casing thereof is mainly made of a material having a high friction coefficient, such as rubber and plastic, and secured on the bottom of the casing with a link member such as a screw, or attached to the bottom of the casing in manner of adhesion, such that the laptop computer can be firmly placed on the desktop with the help of the retarding force formed on the desktop due to the friction force of the pad. However, in certain cases, for example, when a salesman shows data to a customer, the retarding force provided by the pads becomes a burden, such that the user has to uplift the whole laptop computer from the desktop, and turn it to show the content on the screen to the customer. Moreover, after showing, the user has to repeat the same action to operate the laptop computer again. Therefore, in the entire process of showing data, the need of frequent turning causes much inconvenience in use, and the inner operation devices, such as Central Processing Unit (CPU), are easily to be damaged due to the shock resulting from the frequent lifting up and putting down of the computer. Or, the computer suffers from the risk of falling off to the floor because of not being held steadily. Moreover, when the user needs to alter the using position temporarily, for example, when the user wants to alter the operation position to an area near the desktop momentarily, the alternation of the operation position also requires the uplift of the whole laptop computer, thereby resulting in the inconvenience in use.
SUMMARY OF THE INVENTIONAccordingly, the present invention is directed to a pad structure, so as to solve the problem that the laptop computer in the prior art cannot be moved momentarily on a desktop.
As embodied and broadly described herein, the pad structure disclosed in the present invention is disposed on the bottom of a casing of an electronic device, and includes a slide piece and a skidproof piece. The skidproof piece is in contact with a plane, and forms a retarding force with the plane by the friction force of the materials. The static friction force of the material of the slide piece is lower than that of the material of the skidproof piece, so that the interference drag formed by the slide piece with the plane is less than that formed by the skidproof piece with the plane.
The skidproof piece is lifted to leave the plane when the casing of the electronic device is slanted, while the slide piece contacts with the plane simultaneously, such that the casing of the electronic device may move on the plane by the slide piece. Therefore, the staying and moving of the electronic device on the plane can be achieved by the difference between the retarding force formed by the skidproof piece and the slide piece with the plane. In this way, a user can easily move the electronic device on the plane.
The present invention will become more fully understood from the detailed description given herein below for illustration only, and thus are not limitative of the present invention, and wherein:
The housing of an electronic device referred in the present invention is, for example, a housing of a common electronic device such as a computer, a host, and a screen, and the examples above are for the purpose of illustration only, instead of limitation.

The pad structure of the present invention can stably place an electronic device on a plane by a skidproof piece, and when the electronic device is required to be moved, the movement on a plane can be achieved by the use of a slide piece, only through slanting and uplifting one side of the electronic device. The structure of the pad structure is simple, and can not only accomplish the object of fixing or moving electronic device on a plane, but also effectively lower the cost of development and production.
Claims
