Abstract
The present invention is a mouse having a clickable scrolling wheel that includes a locking capability that is activated only when a user performs a clicking operation on the scroll wheel. In one embodiment, when the scroll wheel is depressed downward during a clicking operation, a slat element connected to the scroll wheel engages a non-movable slot, and the scroll wheel is prohibited from scrolling. When the user releases the scroll wheel, the slat element disengages from the slot and the scrolling operation of the scroll wheel is again available. In an alternative embodiment, depressing the scroll wheel during a clicking operation temporarily breaks an electrical connection associated with the scrolling operation of the scroll wheel, so that movement of the scroll wheel about its axis while depressed has no control functionality.

5. A pointing device with a clickable wheel, for controlling an image on a display device, comprising:
-
at least one slat element mounted coaxially to an axle of the wheel, said slat element including a plurality of slats extending in a direction outward from said axle;
at least one slotted element having a slot situated beneath said axle, said slot being aligned with one of said plurality of slats when the wheel is in an at-rest position;
wherein when the wheel is clicked, one of said plurality of slats engages the slot of said at least one slotted element, thereby preventing rotational movement of the wheel about the axle; and
wherein when the wheel is unclicked, the wheel is biased upward so that none of said plurality of slats engage the slot of said at least one slotted element, thereby allowing rotational movement of the wheel about the axle.
