Abstract
Abstract A mechanism for supporting a rack mounted electronic module during both storage and access is disclosed. The mechanism includes side-by-side pais of scissor-like two-bar linkages. Each of the front and rear ends of the mechanism includes four pivot points: on the rear end of the mechanism the two top pivot points are pivotally coupled to the rear of the rack while the two bottom pivot points support a rolling member that rolls vertically along the rack rear wall; on the front end of the mechanism the two top pivot points are pivotally coupled to the rear of the module while the two bottom pivot points support a rolling member that rolls vertically along the module rear wall.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
A rack mounted electronic module support mechanism, comprising: a plurality of two-bar linkages pivotally interconnected for forming an extensible mechanism having front and rear ends; a rear Panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said rear panel; a front panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said front panel; a rear roller pivotally secured to two bottom ends of two of said two-bar linkages; a front roller pivotally secured to two bottom ends of two of said two-bar linkages; said front roller rolling on a surface of said front panel and said rear roller rolling on a surface of said rear panel for maintaining said front and rear panels substantially parallel as said rollers roll along said panels while said mechanism is being extended.
Claim 2
Dependent Claim
146 words
A rack mounted electronic module support mechanism, comprising: a plurality of two-bar linkages pivotally interconnected for forming an extensible mechanism having front and rear ends; a rear Panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said rear panel; a front panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said front panel; a rear roller pivotally secured to two bottom ends of two of said two-bar linkages; a front roller pivotally secured to two bottom ends of two of said two-bar linkages; said front roller rolling on a surface of said front panel and said rear roller rolling on a surface of said rear panel for maintaining said front and rear panels substantially parallel as said rollers roll along said panels while said mechanism is being extended.
Claim 3
Dependent Claim
16 words
The mechanism of claim 1 wherein said front panel includes means for supporting an electronic module.
Claim 4
Dependent Claim
32 words
The mechanism of claim 2 wherein said means for supporting an electronic module includes openings for receiving an extension of said electronic module and locating said electronic module on said front panel.
Claim 5
Dependent Claim
186 words
A rack mounted electronic module support mechanism, comprising: N pair of two-bar linkages, the bars of each two-bar linkage being pivotally intercoupled at their single pivot point; the two-bar linkages of each pair of two-bar linkages coupled in a side-by-side relationship; ones of each of said pair of two-bar linkages pivotally intercoupled at corresponding ends for forming an extensible mechanism having front and rear ends; a rear panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said rear panel; a front panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said front panel; a rear roller pivotally secured to two bottom ends of two of said two-bar linkages; a front roller pivotally secured to two bottom ends of two of said two-bar linkages; said front roller rolling on a surface of said front panel and said rear roller rolling on a surface of said rear panel for maintaining said front and rear panels substantially parallel as said rollers roll along said panels while said mechanism is being extended.
Claim 6
Dependent Claim
186 words
A rack mounted electronic module support mechanism, comprising: N pair of two-bar linkages, the bars of each two-bar linkage being pivotally intercoupled at their single pivot point; the two-bar linkages of each pair of two-bar linkages coupled in a side-by-side relationship; ones of each of said pair of two-bar linkages pivotally intercoupled at corresponding ends for forming an extensible mechanism having front and rear ends; a rear panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said rear panel; a front panel having two pivot points for pivotally securing two top ends of two of said two-bar linkages to said front panel; a rear roller pivotally secured to two bottom ends of two of said two-bar linkages; a front roller pivotally secured to two bottom ends of two of said two-bar linkages; said front roller rolling on a surface of said front panel and said rear roller rolling on a surface of said rear panel for maintaining said front and rear panels substantially parallel as said rollers roll along said panels while said mechanism is being extended.
