Abstract

A portable device having a multi-function belt clip assembly includes a leaf spring 16 having a first end 18 and a second end 20; a housing 14 which has a recess 22 to engage the first end 18 of the leaf spring 16; and a belt clip 12 which has a recess 24 which is used to engage the second end 20 of the leaf spring 16, wherein the leaf spring 16 is adapted to hold the belt clip 12 in a closed position. The leaf spring 16 further allows opening the belt clip 12 from the closed position to engage a belt, and to spring closed when the opening of the belt clip 12 is constrained below a predetermined angular displacement 34. The leaf spring 16 enables the belt clip 12 to remain latched in an open position when the opening of the belt clip 12 exceeds the predetermined angular displacement 34.

Claims

1. A multi-function belt clip assembly, comprising:

a leaf spring having a first end and a second end;

a housing having a recess to engage said first end of said leaf spring;

and

a belt clip, having a recess to engage said second end of said leaf spring, wherein said leaf spring is adapted to hold said belt clip in a closed position,

wherein said leaf spring further allows opening said belt clip from said closed position to engage a belt, and spring closed when said opening of said belt clip is constrained below a predetermined angular displacement, and

wherein said leaf spring enables said belt clip to remain latched in an open position when said opening of said belt clip exceeds said predetermined angular displacement.

2. The multi-function belt clip assembly according to claim 1,

wherein said leaf spring flexes in a first direction to maintain said belt clip in a closed position, and further

wherein said leaf spring flexes in a second opposite direction to maintain said belt clip in an open position.

3. The multi-function belt clip assembly according to claim 2,

wherein said belt clip rotates about a pivot, and

wherein said leaf spring applies a force in a first direction at an end of said belt clip about said pivot to maintain said belt clip in a closed position, and

wherein said leaf spring applies a force in a second opposite direction at the end of said belt clip about said pivot to maintain said belt clip in said open position.

4. The multi-function belt clip assembly according to claim 3, wherein opening said belt clip beyond said predetermined angular displacement causes said leaf spring to buckle, thereby causing said leaf spring to flex in said second opposite direction.

5. The multi-function belt clip assembly according to claim 4, wherein said belt clip includes a boss, wherein when said belt clip is being closed said boss initiates a buckling of said leaf spring, thereby causing said leaf spring to spring back into said first direction.

6. A multi-function belt clip assembly, comprising:

a housing;

a belt clip; and

a leaf spring secured at a first end by said housing and secured at a second end by said belt clip,

wherein said leaf spring maintains said belt clip in a closed position when said belt clip is opened to less than a predetermined angular displacement, and further wherein said leaf spring maintains said belt clip in an open position when said belt clip is opened to greater than the predetermined angular displacement.

7. The multi-function belt clip assembly according to claim 6,

wherein said leaf spring flexes in a first direction to maintain said belt clip in said closed position, and further

wherein said leaf spring flexes in a second direction opposite said first direction to maintain said belt clip in said open position.

8. The multi-function belt clip assembly according to claim 7, wherein opening said belt clip to greater than said predetermined angular displacement causes said leaf spring to buckle, thereby causing said leaf spring to flex in said second direction.

9. The multi-function belt clip assembly according to claim 8, wherein said belt clip includes a buckling initiator positioned at a position along said belt clip, wherein said buckling initiator causes said leaf spring which is flexed in said second direction to buckle when said belt clip is being closed, thereby causing said leaf spring to spring back in said first direction.

10. The multi-function belt clip assembly according to claim 6, wherein said housing is a holster to enable carrying a portable device.

11. The multi-function belt clip assembly according to claim 6, wherein said housing contains a portable device.

12. A multi-function belt clip assembly, comprising:

a housing having a pivot;

a belt clip having a first end and a second end, and coupled to said pivot; and

a leaf spring secured at a first end by said housing and secured at said second end by said belt clip,

wherein finger pressure applied to said first end of said belt clip causes said belt clip to open about said pivot, and wherein said leaf spring maintains said belt clip in an open position when said belt clip is opened to greater than a predetermined angular displacement, and

wherein said finger pressure applied to said second end of said belt clip causes said belt clip when in said open position to close about said pivot, wherein said leaf spring maintains said belt clip in a closed position.

13. The multi-function belt clip assembly according to claim 12,

wherein said finger pressure applied to said first end of said belt clip causes said belt clip to open about said pivot, and wherein said leaf spring causes said belt clip to close when said finger pressure is released, and said belt clip is opened to less than the predetermined angular displacement.

14. The multi-function belt clip assembly according to claim 12,

wherein said leaf spring flexes in a first direction to maintain said belt clip in said closed position, and further

wherein said leaf spring flexes in a second direction opposite said first direction to maintain said belt clip in said open position.

15. The multi-function belt clip assembly according to claim 14, wherein opening said belt clip to greater than said predetermined angular displacement causes said leaf spring to buckle, thereby causing said leaf spring to flex in said second direction.

16. The multi-function belt clip assembly according to claim 15, wherein said belt clip includes a buckling initiator positioned at a position along said belt clip, wherein said buckling initiator causes said leaf spring which is flexed in said second direction to buckle when said belt clip is being closed, thereby causing said leaf spring to spring back in said first direction.
