Tumbler mouse

1. Technical Field

The present disclosure relates to mice, and particularly, to a tumbler mouse for desktop computer, notebook and etc.

2. Description of Related Art

A mouse is a hand-held, button-activated pointing/inputting device used in a computer. The mouse directs an indicator to move in a computer screen, and is configured for selecting operations or texts or graphics. However, this kind of the mouse usually has limited functions and lacks creativity.

Therefore, there is a room for improvement within the art.

Many aspects of mouse can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, the emphasis instead being placed upon clearly illustrating the principles of the present mouse. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 is an exploded, isometric view of a tumbler mouse according to an exemplary embodiment.

FIG. 2 is an assembled view of the tumbler mouse shown in FIG. 1 .

FIG. 3 is a partially cross-sectional view of the tumbler mouse shown in FIG. 2 .

FIG. 4 is a schematic view of the tumbler mouse lying on a support surface.

FIG. 5 is a schematic view of the tumbler mouse standing on the support surface shown in FIG. 4 .

FIG. 6 is a partially cross-sectional view of the tumbler mouse according to another exemplary embodiment.

FIG. 1 and FIG. 2 show an exemplary embodiment of a tumbler mouse 100 including an upper housing 10 , a lower housing 30 , and a balancing weight 50 .

The upper housing 10 includes a first curved wall 12 . A button 14 and a roller 16 are formed at one end of the first curved wall 12 . The buttons 14 can operate menu and etc. The roller 16 can turn pages and etc.

The lower housing 30 includes a wall 32 and a second curved wall 34 connecting to the wall 32 . The wall 32 and the second curved wall 34 define a receiving chamber 38 for accommodating the balancing weight 50 , electronic components (not shown) and etc. One or more symmetric plates 39 are secured on an inside surface of the second curved wall 34 and accommodated in the receiving chamber 38 . The balancing weight 50 can be positioned by the plates 39 .

Referring to FIG. 3 , the balancing weight 50 can be made of metal, and includes a planar surface 52 and an arcuate surface 54 opposite to the planar surface 52 . The planar surface 52 can abut the plates 39 . The arcuate surface 54 can match with the first curved wall 12 and the second curved wall 34 . Thus, the balancing weight 50 can be secured in the tumbler mouse 100 . The weight of the balancing weight 50 should heavy enough so that when the tumbler mouse 100 is in a standing condition (shown in FIG. 5 ), the tumbler mouse 100 can sway as a tumbler. However, when the tumbler mouse 100 is pressed on a support surface 90 (shown in FIG. 4 ) by an external force, the tumbler mouse 100 can not automatically stand up.

Referring to FIGS. 4 and 5 , in assembly, the balancing weight 50 is positioned by the plates 39 . One portion of the arcuate surface 54 matches with the second curved wall 34 . Thus, the balancing weight 50 is secured in the lower housing 30 . The upper housing 10 is assembled on the lower housing 30 . The arcuate surface 54 matches with the first curved wall 12 . Thus, the balancing weight 50 is secured in the tumbler mouse 100 .

When the tumbler mouse 100 is placed on the support surface 90 in a lying condition (shown in FIG. 4 ), a support point 322 is defined at a junction of the second curved wall 34 and the wall 32 . An imaginary plane 40 , which passes through the support point 322 and is perpendicular to the support surface 90 , is defined. The tumbler mouse 100 is divided into a main portion 60 and a swaying portion 80 by the imaginary plane 40 .

The balancing weight 50 makes the tumbler mouse 100 have a center of gravity 70 located in the main portion 60 . The center of gravity 70 is positioned so when the tumbler mouse 100 is pressed towards the support surface 90 by an external force, the tumbler mouse 100 can not automatically stand up.

However, the positioning of the center of gravity 70 also assures that when the tumbler mouse 100 is stood vertically on the support surface 90 at a contacting point 122 , a distance between the center of gravity 70 and the contacting point 122 L 3 is less than any distances L 1 and L 2 from the center of gravity 70 to the first curved wall 12 or second curved wall 34 . With this weight balance 50 , the tumbler mouse 100 can sway around the contacting point 122 as a tumbler.

The tumbler mouse 100 can sway as a tumbler on the support surface 90 , and when is pressed on the support surface 90 by an external force, the tumbler mouse 100 can not automatically stand up. Operators can use the tumbler mouse 100 as an input device. When the operators apply a force to drive the tumbler mouse 100 to stand up, the tumbler mouse 100 can sway as a tumbler on the support surface 90 again. Therefore, the tumbler mouse 100 is not only as an input device but also as a toy. The tumbler mouse 100 can bring enjoyment to work.

It is to be understood, the plates 39 can be omitted, the balancing weight 50 can be attached to the lower housing 30 by adhesive 41 (shown in FIG. 6 ) according to another exemplary embodiment. In addition, the plate 39 may adopts other configuration function as latching plate to fix the balancing weight 50 in the chamber 38 .

It is to be understood, the upper housing 10 and the lower housing 30 can be seemed as an integral a housing, correspondingly, the first curved wall 12 and the second curved wall 34 can be seemed as an integral curved wall.

It is to be understood, however, that even through numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
