Description

Mobile Mouse {Mouse for computer}

The present invention relates to a computer mouse that is easy to move, and more particularly, by laying a ball on the bottom of the mouse and the mouse to move the cloud by the ball to minimize friction with the bottom surface to have a precise and smooth movement It relates to a computer mouse.

The mouse for a computer relates to an input device for allowing a cursor on a monitor to move by detecting a movement of the mouse by a track ball or an optical sensor formed at the bottom of the center and converting the mouse into an electrical signal.

Therefore, to smoothly work, the movement of the cursor must be finely adjusted. To this end, various efforts are being made to facilitate the movement of the mouse.

In other words, the method of forming a smooth lubricating surface on the bottom of the mouse or by using a smooth mouse pad to minimize the friction between the mouse and the bottom is generally used. However, the bottom of the mouse is slid from the bottom surface. The movement is to have a closed end that can not be considered to some degree of friction, and when the mouse is used for a long time, the lubricating surface is worn out, the movement is not good, and in severe cases, the mouse has to be discarded.

The present invention has been made in order to facilitate the movement of the mouse to enable precise computer work, the present invention is composed of an upper case and a lower case and a computer mouse having a cloud device on the bottom of the lower case outer part of the mouse Forming a ball housing with a through hole in the lower, and embedded in the ball housing to enable the ball movement of the mouse, and then covered with a cap and provided with a plurality of cloud devices configured to prevent the ball from being separated To provide a mouse.

The present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view for showing the configuration of the present invention, the present invention forms a plurality of ball housing 110 in the lower case so that the bottom surface of the mouse 1 can be supported in a stable and balanced state from the bottom surface And, the ball housing 110 has a ball 120 to enable the rolling movement of the mouse.

At this time, one end of the lower portion of the ball 120 should be exposed in the ball housing 110, but must maintain a protruding state than the bottom of the mouse (1).

To this end, the through hole 111 is formed below the ball housing 110, and the inclined surface 111 a is formed around the through hole 111 to facilitate the exposure and rotation of the ball 120.

The cap 130 is a means for preventing the ball 120 from being separated from the ball housing 110, it is coupled by the cap coupling means of the ball housing 110.

The cap coupling means of the ball housing 110 is most preferably to be screwed by a screw 112 formed on the outer peripheral surface of the ball housing 110 and the screw portion formed on the inner peripheral surface of the cap 130 as shown in FIG. Various well-known coupling methods can also be utilized within the structure and the range which does not deviate from the scope of the present invention.

1 to 3 illustrate a first embodiment of the present invention, since the first embodiment of the present invention has a structure in which one ball 120 rotates in the ball housing 110 and the side surface of the ball 120. The upper portion is in contact with the cap 130 or the ball housing 110, the friction is generated, which may be inconvenient for sensitive mouse users.

Therefore, the present invention further proposes a rolling device having the same structure as that of the second embodiment and the third embodiment by further improving the first embodiment of the present invention.

First, as shown in FIGS. 4 to 5, the second embodiment forms another ball 121 at the top of the ball 120 to minimize the friction of the ball 120. By reducing the friction applied to the facilitate the rotation of the ball (120).

However, even in the case of the second embodiment, the friction applied to the side of the ball 120 has no way to solve the side having a ball coupled to enable the rolling motion as shown in the third embodiment shown in Figures 6 and 7 The bearing 125 and the upper bearing 126 are fixed to the inner circumferential surface of the ball housing 110 and the inner circumferential surface of the cap 130b to minimize the friction with the ball 120 to facilitate the rotation of the ball 120.

In the present invention, the ball 120 to be in direct contact with the bottom surface in the rolling motion should have a good friction force, so it is preferable to use a metal ball or rubber beads made of rubber coated material in the case of Example 1 ball 120 Since only one) is used, it is preferable to use a material having a smooth surface, that is, a metal ball or a plastic ball, in order to avoid friction in the ball housing 110.

However, in the case of Embodiments 2 and 3, since the frictional force can be minimized by another ball inside the ball housing 110, the ball 120 is preferably rubber coated or a material having a large friction coefficient. Of course, the ball 121 used to support the ball 120 inside the ball housing 110 or the ball coupled to the bearings 125 and 126 is preferably made of a material having a low coefficient of friction.

As described above, the mouse 1 of the present invention is supported from the bottom surface by the ball 120 protruding into the plurality of ball housings 110 formed in a balanced position, so that the ball 120 has a sense of stability as well. Since it moves along the cloud movement, it can move very smoothly and precisely.

As described above, the present invention allows a plurality of balls to be formed on the bottom of the mouse and the ball moves to the ball by rolling, thereby minimizing friction between the mouse and the bottom surface, thereby enabling precise and smooth movement of the mouse. It is to have a comfortable and efficient computer operation is possible.
