Abstract
A handle having a handle body, a latching arm, and a pivot block is provided. The handle body has a release finger and a pivot leg. The latching arm is slideably secured to the handle body. The pivot block is connectable to a device having at least one movable component. The pivot block is also connected to a first portion of the pivot leg so as to allow the handle body to rotate in the pivot block about the first portion between a first position and a second position. The first position is a locked position and the second position is a latched position.
Claims6
A pluggable cartridge, comprising:
- a first wall;
- a second wall, said first and second walls having a bottom edge;
- a printed circuit card being housed within and protected by said first and second walls so as to be moveable with respect to said bottom edge;
- a pivot block secured to said first wall;
- a handle movably connected to said pivot block so as to be movable between a first position and a second position, a portion of said handle being attached to said printed circuit card by an articulated mechanical linkage such that movement of said handle to said first position causes said printed circuit card to move to a position proximate said bottom edge and such that movement of said handle to said second position causes said printed circuit card to move a position remote from said bottom edge;
- and
- a latching arm slideably secured to said handle, said first position defining a locked position having a portion of said handle lockably engaged with said pivot block, and said second position defining a latched position having a portion of said latching arm slid toward said pivot block so as to be latchably engaged with said pivot block.
A method of securing and unsecuring a pluggable cartridge in a structure, comprising:
- moving a handle to a first position, said handle being connected to a first movable portion of said pluggable cartridge, said first movable portion of said pluggable cartridge being secured in a first desired position when in said first position;
- sliding said pluggable cartridge into said structure until said first movable portion is in a facial spaced relationship with a portion of said structure;
- depressing a release arm of said handle to unsecure said first movable portion from said first desired position;
- and
- moving said handle to a second position to move said first movable portion to a second desired position, said second desired position being defined by said first movable portion being seated in said portion of said structure, said second position being configured to secure said second movable portion of said pluggable cartridge in said second desired position.
