Abstract

Abstract A locking and extraction mechanism for a rack mounted component uses a selectively actuable extraction hook slideably retained in a lock block for engaging in a first position of the hook a peripheral edge of the rack mounted assembly. The hook is connected to a handle which is grasped by an operator to enable the rack mounted assembly to be partially withdrawn from the rack and concurrently disconnected from an electrical connector mounted on the rack. Conversely, subsequent to the rack assembly being fully inserted into the rack to make electrical connections with the electrical connector, the hook is longitudinally rotated by a rotation of the handle to a second position wherein the handle is against the face of the rack mounted component to lock the component into the rack while the hook concurrently engages a surface on the lock block to prevent the handle from being withdrawn.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 221 words
A combined lock and extractor comprising a handle selectively positionable between a first position and a second position, a U-shaped hook having one end connected to said handle, a lock block having an aperture extending therethrough, support means for slidably supporting said hook in said lock block to enable a second end of said hook to contact a surface of said lock block within said aperture in said first position of said handle and to pass along an outside surface of said lock block in said second position of said handle and mounting means for mounting said lock block in a support rack adjacent to a rack mounted apparatus located in said support rack whereby said first position of said handle is effective to prevent removal of said rack mounted apparatus from said support rack and said second position of said handle is effective to allow a removal of said rack mounted apparatus from said support rack, said second end of said hook being arranged to contact said rack mounted apparatus in said second position of said handle to transmit a force applied to said handle to said rack mounted apparatus to assist in removing said apparatus from said support rack and said handle being arranged to contact a front face of said apparatus in said first position of said handle.
Claim 2
Dependent Claim 221 words
A combined lock and extractor comprising a handle selectively positionable between a first position and a second position, a U-shaped hook having one end connected to said handle, a lock block having an aperture extending therethrough, support means for slidably supporting said hook in said lock block to enable a second end of said hook to contact a surface of said lock block within said aperture in said first position of said handle and to pass along an outside surface of said lock block in said second position of said handle and mounting means for mounting said lock block in a support rack adjacent to a rack mounted apparatus located in said support rack whereby said first position of said handle is effective to prevent removal of said rack mounted apparatus from said support rack and said second position of said handle is effective to allow a removal of said rack mounted apparatus from said support rack, said second end of said hook being arranged to contact said rack mounted apparatus in said second position of said handle to transmit a force applied to said handle to said rack mounted apparatus to assist in removing said apparatus from said support rack and said handle being arranged to contact a front face of said apparatus in said first position of said handle.
Claim 3
Dependent Claim 30 words
A combined lock and extractor as set forth in claim 1 wherein said mounting means is arranged to mount said lock block above said apparatus and adjacent to said apparatus.
Claim 4
Dependent Claim 32 words
A combined lock and extractor as set forth in claim 2 wherein said aperture has a step for engaging said second end of said hook in said first position of said hook.
Claim 5
Dependent Claim 26 words
A combined lock and extractor as set forth in claim 1 wherein said handle has a major axis substantially perpendicular to a plane of said hook.
Claim 6
Dependent Claim 34 words
A combined lock and extractor as set forth in claim 1 wherein said support means includes a bushing extending through said lock block between said aperture and an outside surface of said lock block.
