Docking mechanism for locking and undocking multiple electronic instruments

1. A docking instrument system comprising:

a lower electronic instrument unit having a top cover;

at least one hook aperture and at least one lift pusher aperture in the top cover;

a button aperture on a side wall of the lower electronic instrument unit;

a sliding hook piece including a button at an end of the sliding hook piece that extends through the button aperture, at least one hook that extends through the hook aperture, and at least one lift pusher that extends from a first part of a flat portion of at least one lifting pushing lever and extends through the lift pusher aperture, wherein the sliding hook piece is slidably attached to the top cover; and the flat portion pivots about a hinge; and

a second part of the flat portion located on one side of the hinge that sides upon a ramp on an interior top surface of the top cover, the ramp causing the lift pusher to move upward on the other side of the hinge when the button is pressed.

2. The docking instrument system of claim 1 , wherein the sliding hook piece comprises:

a generally planar body that is parallel to the interior top surface of the top cover, the hook extending upward from the planar body, and

at least one lifting pushing lever from which the lift pusher extends upward; wherein the lifting pushing lever slide on the lifting means to cause the lift pusher to move upward when the button pressed.

3. The docking instrument system of claim 2 , wherein the lifting pushing lever comprises a flat portion that pivots about a pivot hinge, one part of the flat portion on one side of the pivot hinge supports the lift pusher and a second part of the flat portion on a second side of the pivot hinge engages the lifting means when the button pressed, wherein the flat portion rotates about the pivot hinge as the second part engages the lifting means that causes the lift pusher to move upward.

4. The docking instrument system of claim 3 , wherein the second part of the flat portion slides up the ramp when the button in pressed causing the flat portion to rotate.

5. The docking instrument system of claim 4 , wherein

the interior top surface of the top cover includes at least one retaining rib; and

the sliding hook piece includes at least one spring finger that is spring loaded on the retaining rib to urge the sliding hook piece toward the button aperture.

6. The docking instrument system of claim 5 , wherein the interior top surface of the top cover includes at least one retention tab that each form a slot that holds an edge of the pivot hinge, wherein the retention tab permits the sliding hook piece to be slidably attached to the top cover.

7. The docking instrument system of claim 6 , wherein the generally planar body of the sliding hook piece includes a front strip portion from which the button extends and an opposing back strip portion with flat protrusion or edge;

wherein the flat protrusion or edge is positioned within at least one edge slot formed by at least one edge retention tab that forms from the interior top surface of the top cover; and

wherein the edge retention tab also permits the sliding hook piece to be slidably attached to the top cover.

8. The docking instrument system of claim 1 , further comprising an upper electronic instrument unit that docks on the top cover of the lower electronic instrument unit, wherein the upper electronic instrument unit comprises at least one hook receiving aperture that engages the hook.

9. The docking instrument system of claim 8 , further comprising:

at least one guide pin aperture in the upper electronic instrument unit; and

at least one guide pin that extends upward from the top cover; wherein the guide pin enters the guide pin aperture to align the upper electronic instrument unit with the lower electronic instrument unit.

10. The docking instrument system of claim 8 , further comprising:

feet extending downward from the upper electronic instrument unit; and

feet pockets on the top cover; wherein the feet enter the feet pockets to align the upper electronic instrument unit with the lower electronic instrument unit.

11. The docking instrument system of claim 2 , wherein the sliding hook piece is a generally planar body that is parallel to an interior top surface of the top cover, the generally planar body comprises:

a front strip portion from which the button extends;

an opposing back strip portion with flat protrusion or edge;

opposing back strip portion; and

a hollow central region defined by the front strip portion, opposing back strip portion, and the two side portions.

12. The docking instrument system of claim 11 , wherein

the lower electronic instrument unit has vents in the top cover; and

the hollow central portion is directly under at least one of the vents to permit air flow between the interior of the lower electronic instrument unit and the vents.

13. The docking instrument system of claim 8 , wherein

the lower electronic instrument unit has vents in the top cover;

the upper electronic instrument unit comprises bottom vents on a bottom side that face the top cover;

the sliding hook piece is a generally planar body that is parallel to an interior top surface of the top cover, the generally planar body comprises:

a front strip portion from which the button extends;

an opposing back strip portion with flat protrusion or edge;

two side strip portions that extend between the front strip portion and the opposing back strip portion; and

a hollow central region defined by the front strip portion, opposing back strip portion, and the two side portions.

14. The docking instrument system of claim 1 , further comprising:

an upper electronic instrument unit that docks on the top cover of the lower electronic instrument unit, wherein the upper electronic instrument unit comprises at least one hook receiving aperture that engages the hook and an electronic connector on a bottom side that faces the top cover; and

a lower electronic connector of the lower electronic instrument unit that engages the electronic connector.

15. The docking instrument system of claim 14 , further comprising:

at least one guide pin aperture in the upper electronic instrument unit; and

at least one guide pin that extends upward from the top cover; wherein the guide pin enters the guide pin aperture to align the upper electronic instrument unit with the lower electronic instrument unit and connect the lower electronic connector with the electronic connector.
