1. Field of the Invention
The invention relates to a foldable computer mouse, and particularly to a wireless and foldable optical mouse.
2. Description of the Related Art
The computer mouse is a kind of computer pointing device for controlling the movement of the cursor on the screen. To meet the demand of less in size, the spare space is usually reduced and by the conventional technology. A blemish in an otherwise perfect thing is that reducing the size of the mouse will also reduce the contact surface between the mouse and the user. Therefore, the reformed products are produced in order to avoid the above-mentioned disadvantages.
Referring to FIG. 1A, the three-dimensional view of the operational configuration of the conventional portable mouse is illustrated. The portable mouse 100 is a wired mouse including a cable 110, and each side of the housing 102 includes a track respectively. The cover 108 can fit the mouse body 102 with an aid of the track and slide along the track. The two buttons 104 comes into being one part of the mouse body 102. In the FIG. 1A, the cover 108 of the portable mouse 100 slides to the first location and the portable mouse 100 is presented in the operational configuration.
FIG. 1B is a state diagram illustrating the conventional portable mouse, which lies in between the operational configuration and compact form. The location of the cover 108 is between the operational configuration and the compact form. When the cover 108 slides towards the direction 112, the portable mouse 100 is in the operational configuration. On the other hand, when the cover 108 slides towards the direction 114, the top surface of the portable mouse 100 is covered by the cover 108 and the portable mouse 100 is in the compact form.
FIGS. 2A to FIG. 2C illustrate another conventional reducible mouse. FIG. 2A illustrates the three-dimensional view of the conventional foldable computer mouse. FIG. 2B illustrates the three-dimensional view of the compact form of the conventional foldable computer mouse.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 3A is the three-dimensional view of the extension form of the foldable computer mouse according to the preferred embodiment of the present invention. FIG. 3B is a three-dimensional view illustrating another side view of the foldable computer mouse depicted in FIG. 3A. The foldable computer mouse includes the mouse body 302, the sensor 305 and the extension part 308. The bottom of the mouse body 302 includes a receiving space 304 acting as a receiving space to receive and embed the extension part and a bottom contact surface 306. The sensor 305 is disposed on the bottom contact surface 306 for detecting the motion of the mouse relative to the plane. Furthermore, a hinge 310 is disposed on one side of the mouse body 302 and adjacent to the receiving space 304. The mouse body 302 and the extension part 308 are pivotally connected together by the hinge 310. The location of hinge is preferably to be on the top of the side wall close to the user of the mouse body 302. The top surface 320 of the mouse body 302 is used to support the user's palm. At least one button 316 is exposed out of the top surface 320 for operating by users. When the extension part 308 rotates outwards to the predetermined location outside of the accepting space (as shown in 3A), the extension part 308 and the mouse body 302 together form a upper surface 350, and therefore the upper contact surface 350 between the mouse and the users is increased. In other words, the mouse body 302, the top surface 320 and the extension part 308 together can support the user's palm. Accordingly, the upper contact surface 350 between the foldable computer mouse 300 and the users is increased and users' comfort is enhanced.
On the other hand, when the extension part 308 rotates inwards along the direction 314 into the receiving space 304, the size of the foldable computer mouse is reduced for easy storage. At the same time, the sensor 305 is exposed out of the bottom contact surface 306 of the mouse body 302 so that the sensor 305 can continue detecting the motion of the mouse relative to the plane, such as the working surface 402. Therefore, no matter the extension part 308 rotates outwards to the predetermined location or rotates inside the receiving space 304, users can operate the foldable computer mouse 300. In other words, the body 302 and the extension part 308 can rotate relative to the hinge 310 for changing the operational form of the foldable computer mouse. When the extension part 308 rotates to the predetermined location (as shown in 3A), the foldable computer mouse 300 is in an extension form. When the extension part 308 is located inside the receiving space 304, the foldable computer mouse is in a compact form.
The capacity of the receiving space 304 is bigger than the volume of the extension part 308 so that the extension part 308 can be embedded inside the receiving space 304 completely. Therefore, when extension part 308 is located inside the receiving space 304, the foldable computer mouse is in a compact form, and users can still operate the foldable computer mouse 300 as usual. The bottom surface of the receiving space 304 of the foldable computer mouse 300 is a slope, that is to say, the depth of the receiving space 304 turns from deep to shallow. The receiving space 304 extends from the top of the side wall close to the user to the sensor 305. The hinge 310 is located in the deepest spot. The setup of the slope makes use of the spare space of the mouse body 302 efficiently.
Referring to FIGS. 3B, 4A and 4B, FIG. 4A illustrates the lateral view of the extension form of the foldable computer mouse according to the preferred embodiment of the present invention. FIG. 4B illustrates the lateral view of the lifted extension part of the foldable computer mouse. The extension part 308 includes the first side 308a and a second side 308b. The first side 308a is pivotally connected to the mouse body 302 by the hinge 310. The second side 308b is opposite to the first side 308a. When the extension part 308 rotates outwards to the predetermined location, the second side 308b and the bottom contact surface of the mouse body 302 are located on the same plane, such as the working surface 402. In other words, the upper edge of the extension part 308 connects with the top of the side wall of the mouse body 302 close to the user, and the lower edge of the extension part 308 connects with the plane. Therefore, when users operate the foldable computer mouse 300 in the extension form, the pressure from the palm can be distributed to the bottom 306, hinge 310 and the second side 308b and stabilize the structure of the extension form. The computer mouse 300 further includes elastic elements disposed between the upper edge of the extension part 308 and the mouse body 302. The example of the elastic elements is the spring 322 disposed inside the hinge 310 for providing an elasticity which rotates the extension part 308 towards the receiving space 304.
Referring to FIG. 5A, 5B, FIG. 5A illustrates the top view of the compact form of the foldable computer mouse according to the preferred embodiment of the present invention. FIG. 5B illustrates the bottom view of the foldable computer mouse depicted in the FIG. 4A. The extension part 308 of the preferred embodiment is an ergonomic plate. The surface of the ergonomic plate is curved to fit the radian of the palm. The configuration of the ergonomic plate and the shape of the receiving space 304 match substantially. For example, the bottom of the receiving space 304 includes a radian and the radian of the receiving space 304 matches the radian of the ergonomic plate substantially. Another example is the lower edge of the extension part is a pre-design curve, and the receiving space 304 includes the same shape of the pre-design curve substantially. In addition, the bottom of the mouse body 302 further includes an extension receiving space 318, which acts as finger insertion space allowing user's finger insertion to lift the extension part 308. The extension receiving space 318 and the receiving space receiving space 304 are communicated.
The design of the extension part 308 can not only resolve the conflict between the reduced size and the comfort, but also achieve two forms to meet the demands for both short and long operation.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
