Abstract

A key-free mouse includes a top cover and a bottom cover connected to each other through a pivotal connection of locking pins to locking slots. The locking pins and the locking slots are respectively provided at inner side of the top and the bottom covers at front and rear ends of a longitudinal axis thereof, so that the top cover is pivotally turnable about the longitudinal axis by a predetermined degree relative to the bottom cover to actuate a left or a right switch provided in the mouse. Elastic elements such as springs are provided in the mouse separately at predetermined positions for providing the top cover with suitable supporting elasticity to recover from a pivotally turned and laterally inclined position.

Claims

1. A key-free mouse, comprising a top cover and abottom cover connected to each other to define an internal space for receiving a circuit board therein;

said top and said bottom covers being provided in an inner side preferably at front and rear ends of a longitudinal centerline thereof with two locking pins and two locking slots, respectively, so that a longitudinal pivot axis A-A′

is defined between a front set and a rear set of said locking pin and said locking slot that engage with each other to connect said top cover to said bottom cover, and said top cover being adapted to pivotally turn about said pivot axis A-A′

by a predetermined degree relative to said bottom cover; and

said top cover being provided in an inner surface at positions corresponding to a left and a right switches provided on said circuit board with a left and a right strip having a predetermined length, such that when said top cover is pivotally turned about said pivot axis A-A′ and

becomes laterally inclined, either said left or said right strip is brought to press against an elastic key provided on each of said left and said right switches to make said mouse.

2. The key-free mouse as claimed in claim 1, wherein said left and said right strips respectively have an elastic element of a predetermined elasticity connected thereto for providing a supporting elasticity needed for said top cover to recover from a pivotally turned and laterally inclined position.

3. The key-free mouse as claimed in claim 1, wherein said locking slot provided at the front end of said bottom cover has an elastic element of a predetermined elasticity provided therein to locate below said locking pin at the front end of said top cover for providing a supporting elasticity to said front locking pin when said top cover is pivotally turned.

4. The key-free mouse as claimed in claim 2, wherein said elastic elements are springs.

5. The key-free mouse as claimed in claim 3, wherein said elastic element is a spring.

6. The key-free mouse as claimed in claim 1, wherein said bottom cover includes a left and a right side wall that respectively have a middle section with an increased height.

7. The key-free mouse as claimed in claim 1, wherein said locking slot provided at the front end of said bottom cover is provided at a top with a guiding bevel, via which said locking pin provided at the front end of said top cover easily slips into said front locking slot under a minor pressure.
