Abstract:
A computer mouse which is collapsible in size is disclosed herein. In one embodiment, the mouse (100) comprises a rigid top cover (200) and a base (300). The cover (200) is pivotally coupled to the base (300) at one end using pins (214,216) located in pin holes (311,312) and arranged for movement selectively to a raised position in which the other end of the cover (200 )is supported by the base (300). To transform the mouse (100 )to a collapsed configuration, the cover (200) is lifted and the base (300) adjusted so that the cover (200 )extends beyond the base (300) which allows the underside of the cover (200 )to collapsed on the base (300) thus reducing the overall size of the mouse (100).
