Abstract
Abstract An apparatus for docking a data processing unit in which a guide plate extends over a portion of the floor of a housing for receiving the bottom of the unit. Two guide members are disposed at the respective ends of the guide plate for receiving corresponding surfaces formed on said unit. Each of the guide members defines a guide surface that increases in size in a direction toward the rear wall for engagement by the corresponding surfaces of the unit to gradually center and lock the unit in the housing as the unit is inserted into the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A docking apparatus for docking a data processing unit having surfaces defined by diagonal undercuts said docking apparatus comprising a housing having a rear wall, a floor extending from said rear wall, a guide plate extending over a portion of the floor for receiving the bottom of the unit, and two guide members respectively disposed at the ends of said guide plate for respectively receiving corresponding surfaces formed on the unit, each of said guide members defining a guide surface that increases in size in a direction toward said rear wall for respectively engaging the surfaces on the unit to gradually guide the unit to a centered and locked position with respect to said housing.
Claim 2
Dependent Claim
115 words
A docking apparatus for docking a data processing unit having surfaces defined by diagonal undercuts said docking apparatus comprising a housing having a rear wall, a floor extending from said rear wall, a guide plate extending over a portion of the floor for receiving the bottom of the unit, and two guide members respectively disposed at the ends of said guide plate for respectively receiving corresponding surfaces formed on the unit, each of said guide members defining a guide surface that increases in size in a direction toward said rear wall for respectively engaging the surfaces on the unit to gradually guide the unit to a centered and locked position with respect to said housing.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 wherein said guide surfaces of said guide members increase in width in a direction towards said rear wall whereby said guide members center and lock the unit laterally with respect to said housing.
Claim 4
Dependent Claim
38 words
The apparatus of claim 1 wherein said guide surfaces of said guide members increase in height in a direction towards said rear wall whereby said guide members center and lock the unit vertically with respect to said housing.
Claim 5
Dependent Claim
29 words
The apparatus of claim 1 wherein said guide surfaces are formed by diagonal undercuts in said respective guide members which correspond to the undercut surfaces formed on the unit.
Claim 6
Dependent Claim
44 words
The apparatus of claim 4 wherein said guide surfaces of said guide members extend in the respective undercuts of the unit, and surfaces of the unit extend in the respective undercuts of said guide members, in said centered and locked position of the unit.
Claim 7
Dependent Claim
16 words
The apparatus of claim 1 wherein said guide members are formed integrally with said guide plate.
Claim 8
Dependent Claim
38 words
The apparatus of claim 1 further comprising a platform extending over said floor of said housing for receiving said guide plate, and means for advancing said platform towards said rear wall of said housing to complete said docking.
Claim 9
Dependent Claim
31 words
The apparatus of claim 1 wherein the upper surface of each of said guide members adjacent its corresponding guide surface acts as a bearing surface for corresponding surfaces of the unit.
