Abstract

Provided is a multi-function, single-piece handle and modular electronic component incorporating same, and a method of inserting and removing the handle from the modular electronic component. The unitary structure of the handle includes insertion and extraction claws that aid in the insertion and extraction of the modular component from a rack mount upon rotation of the handle to an upward, and vertically extended position respectively. The handle also includes a stowage locking mechanism that maintains the handle in a stowed position on the front of the modular component. A rack locking mechanism is also provided integral with the handle to secure the modular component in its rack mount position. Affirmative user actuation is then required to allow the modular component to be removed therefrom. Outrigging mounting and support legs are also included to add rigidity and strength to the handle to allow it to be used to carry the modular component. By design, the handle may be inserted and removed from the modular component without the use of any tools, and is secured in place without the requirement of any additional hardware.

Claims

1. A handle, comprising:

a central mounting yoke defining a pivot axle and a secondary follower axle thereon, said yoke further defining a pair of insertion claws and an extraction claw adapted to communicate with an external guide locking head;

a carrying surface integrally formed with said yoke; and

a pair of outrigging mounting and support legs integrally formed with said carrying surface in spaced relationship with said yoke, said outrigging mounting and support legs defining supplemental support pivots in axial alignment with said pivot axle.

2. The handle of claim 1, wherein said outrigging mounting and support legs further define removal inhibitor flanges radially extending beyond said supplemental support pivots along a portion of a circumference thereof, said removal inhibitor flanges being adapted to prevent inadvertent removal of said outrigging mounting and support legs when mounted on an external component.

3. The handle of claim 1, wherein said yoke further defines a stowage locking tab extending inwardly perpendicular to an axis of said yoke and adapted to releasably engage a stowage handle locking window on an external component to hold said handle in place thereon.

4. The handle of claim 1, wherein said yoke further defines a switch activation tab extending inwardly perpendicular to an axis of said yoke, said switch activation tab adapted to engage an external engagement switch when positioned in a stowed position on an external component.

5. The handle of claim 4, wherein said switch activation tab includes an activation bumper positioned thereon.

6. The handle of claim 1, wherein said yoke further defines a rack locking mechanism adapted to removably secure a component on which said handle is mounted to a rack mount chassis in which the component is placed.

7. The handle of claim 6, wherein said rack locking mechanism comprises a locking deflection arm flexibly coupled to said yoke at a first end and forming at a second end thereof a ramped insertion surface and an user depression surface, and wherein said yoke accommodates a deflection of said locking deflection arm from a quiescent locking position to a deflected releasing position.

8. The handle of claim 1, wherein said yoke further defines an extended position support surface extending radially beyond said pivot axial, said extended position support surface adapted to prevent said handle from rotating beyond its extended position when installed on an external component and to provide support for carrying the external component.

9. A modular component, comprising:

a housing having a front surface, said front surface defining a first central window having therein two central concave pivot and support surfaces; and

a handle having a central mounting yoke defining a pivot axle and a secondary follower axle thereon, said handle further defining a carrying surface integrally formed with said yoke; and

wherein said pivot axle is pivotally accommodated within said first central window by said two central concave pivot and support surfaces allowing said handle to be rotated between a parallel and a perpendicular position in relation to said front surface, and wherein said secondary follower axles track along a back side of said central concave pivot and support surfaces when said handle is rotated between said parallel and said perpendicular position.

10. The component of claim 9, wherein said front surface further defines a second and a third window in spaced linear relation to said first window, said second and said third windows having therein a convex pivot and support surface and a concave pivot guide surface, and wherein said handle further including a pair of outrigging mounting and support legs integrally formed in spaced relationship with said yoke, said outrigging mounting and support legs defining supplemental support pivots in axial alignment with said pivot axle, said supplemental support pivots are pivotally accommodated within said second and third windows by said convex pivot and support surface and said concave pivot guide surface.

11. The component of claim 10, wherein said outrigging mounting and support legs further define removal inhibitor flanges radially extending beyond said supplemental support pivots along a portion of a circumference thereof, said removal inhibitor flanges being adapted to prevent inadvertent removal of said outrigging mounting and support legs when mounted in said second and said third windows when said handle in said perpendicular position.

12. The component of claim 9, wherein said front panel further defines a stowage handle locking window, and wherein said yoke further defines a stowage locking tab extending inwardly perpendicular to an axis of said yoke and adapted to releasably engage said stowage handle locking window when said handle is in said parallel position.

13. The component of claim 9, wherein said front panel further defines an activation tab window, and wherein said yoke further defines a switch activation tab extending inwardly perpendicular to an axis of said yoke, said switch activation tab adapted to penetrate said activation tab window when said handle is in said parallel position.

14. The component of claim 13, wherein said switch activation tab includes an activation bumper positioned thereon.

15. The component of claim 9, wherein said front surface further defines a rack lock accommodation groove, and wherein said yoke further defines a rack locking mechanism adapted to removably secure said component to a rack mount chassis in which said component is placed when in said parallel position.

16. The component of claim 15, wherein said rack locking mechanism comprises a locking deflection arm flexibly coupled to said yoke at a first end and forming at a second end thereof a ramped insertion surface and an user depression surface, and wherein said yoke accommodates a deflection of said locking deflection arm from a quiescent locking position to a deflected releasing position, said deflection further being accommodated by said rack lock accommodation groove.

17. The component of claim 9, wherein said yoke further defines an extended position support surface extending radially beyond said pivot axial, said extended position support surface adapted to prevent said handle from rotating beyond its extended position and to provide support for carrying said component by engaging a back side of said front surface.

18. The component of claim 9, wherein said housing further includes a bottom surface defining a follower axial insertion window in proximity to said first central window, and wherein said yoke further defines a pair of insertion claws adapted to communicate with an external guide locking head of a rack into which said component is placed, said insertion claws rotating through said follower axial insertion window when said handle is rotated between said parallel and said perpendicular positions.

19. The component of claim 9, wherein said yoke further defines an extraction claw adapted to communicate with an external guide locking head of a rack into which said component is placed to provide mechanical advantage to remove said component when said handle is rotated from a parallel to a perpendicular position.
