Abstract
Abstract An electronic equipment drawer assembly which has a readily replaceable faceplate assembly mounted on a printed circuit board which in turn, slides into the drawer. To ensure damage does not occur to the printed circuit board, when the drawer is opened or closed by a force applied to the faceplate, the unit is designed so that such a force is transferred directly to the drawer and not through the printed circuit board to the drawer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
An electronic equipment drawer comprising: a cabinet having an opening in its front; a drawer slideably mounted in said cabinet through said opening for movement into or out of the cabinet; and having a front facing the opening in the cabinet; said drawer including opposed sets of tracks for slideably retaining a plurality of circuit boards, said sets of opposed tracks being disposed orthogonal to the direction of movement of the drawer; a faceplate for covering said front of the drawer, the faceplate being mounted on one of the plurality of circuit boards and moveable with said one circuit board as said one circuit board is slid along one of said sets of opposed tracks so that portions of the faceplate are slid into contiguous arrangement with the front of the drawer, whereby a force applied to the faceplate for inserting the drawer is substantially transferred directly to the surface of the front of the drawer and not to said one circuit board.
Claim 2
Dependent Claim
163 words
An electronic equipment drawer comprising: a cabinet having an opening in its front; a drawer slideably mounted in said cabinet through said opening for movement into or out of the cabinet; and having a front facing the opening in the cabinet; said drawer including opposed sets of tracks for slideably retaining a plurality of circuit boards, said sets of opposed tracks being disposed orthogonal to the direction of movement of the drawer; a faceplate for covering said front of the drawer, the faceplate being mounted on one of the plurality of circuit boards and moveable with said one circuit board as said one circuit board is slid along one of said sets of opposed tracks so that portions of the faceplate are slid into contiguous arrangement with the front of the drawer, whereby a force applied to the faceplate for inserting the drawer is substantially transferred directly to the surface of the front of the drawer and not to said one circuit board.
Claim 3
Dependent Claim
83 words
An electronic equipment drawer as defined in claim 1 which is further characterized by: the faceplate and the drawer having mating pairs of keys and keyholes which extend parallel to the tracks so that they slideably engage each other when said one circuit board is inserted in the drawer, whereby a force applied to the faceplate to pull out the drawer is substantially transferred directly through the mating pairs of keys and keyholes to the drawer and not to said one circuit board.
Claim 4
Dependent Claim
78 words
An electronic equipment drawer as defined in claim 2 further characterized by: each of the plurality of circuit boards is slideably inserted into the drawer from one side thereof along the opposed sets of tracks with the leading edge of each board first and the trailing edge last, and the mating pairs of keys and keyholes are located substantially adjacent the leading and trailing edges of the faceplate when said one circuit board is inserted in the drawer.
Claim 5
Dependent Claim
60 words
An electronic equipment drawer as defined in claim 3 further characterized by: the faceplate includes a side portion which extends rearwards from the trailing edge of the faceplate beyond said one circuit board and perpendicular to the face of the faceplate so as to prevent damage to said one circuit board when a pulling force is applied to the faceplate.
Claim 6
Dependent Claim
32 words
An electronic equipment drawer as defined in claim 4 further characterized by: the faceplate is mounted in parallel spaced relationship to said one circuit board by a plurality of spacers located therebetween.
Claim 7
Dependent Claim
47 words
An electronic equipment drawer as defined in claim 5 characterized by: means for latching said one circuit board in an inserted position in the drawer so as to maintain contact between the mating pairs of keys and keyholes when a sideward force is applied to the faceplate.
