Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
121 words
An apparatus comprising: a chassis; a removable enclosure extending around said chassis; and at least one manually actuable latch attached to one of said chassis and enclosure and releasably connectable to the other of said chassis and enclosure, said at least one manually actuable latch comprising: a fixed end fixed to said one of said chassis and enclosure, a movable end opposite said fixed end and releasably connectable to said other of said chassis and enclosure, and at least two flexible cantilevered arms connected together at said movable end and interconnecting said fixed end and said movable end for constraining said movable end to move translationally in an imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 2
Independent Claim
121 words
An apparatus comprising: a chassis; a removable enclosure extending around said chassis; and at least one manually actuable latch attached to one of said chassis and enclosure and releasably connectable to the other of said chassis and enclosure, said at least one manually actuable latch comprising: a fixed end fixed to said one of said chassis and enclosure, a movable end opposite said fixed end and releasably connectable to said other of said chassis and enclosure, and at least two flexible cantilevered arms connected together at said movable end and interconnecting said fixed end and said movable end for constraining said movable end to move translationally in an imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 3
Dependent Claim
51 words
The apparatus of claim 1 wherein said at least one manually actuable latch further includes a third flexible cantilevered arm interconnecting said fixed end and said movable end for constraining said movable end to move translationally in an imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein said movable end includes a locking tab for releasably engaging said chassis, and a manually actuable release lever.
Claim 5
Dependent Claim
32 words
The apparatus of claim 3 wherein said fixed end is fixed to an inner surface of said enclosure, and said manually actuable release lever projects through an opening formed in said enclosure.
Claim 6
Dependent Claim
28 words
The apparatus of claim 4 wherein said enclosure includes a front wall, said fixed end being attached to said front wall, said movable end being movable substantially vertically.
Claim 7
Dependent Claim
19 words
The apparatus of claim 5 wherein there are two said latches disposed adjacent respective ends of said front wall.
Claim 8
Dependent Claim
24 words
The apparatus of claim 6 wherein each of said cantilevered arms taper-down in a dimension perpendicular to the imaginary plane toward said movable end.
Claim 9
Dependent Claim
58 words
The apparatus of claim 1 further including: a guide attached to said removable enclosure; and wherein said movable end of said at least one manually actuable latch is slidably retained by said guide such that said movable end is constrained to move translationally in the imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 10
Independent Claim
114 words
An apparatus comprising: a chassis; a removable enclosure extending around said chassis; and at least one manually actuable latch attached to one of said chassis and enclosure and releasably connectable to the other of said chassis and enclosure, said at least one manually actuable latch comprising: a fixed end fixed to said one of said chassis and enclosure, a movable end opposite said fixed end and releasably connectable to said other of said chassis and enclosure, and at least three flexible cantilevered arms interconnecting said fixed end and said movable end for constraining said movable end to move translationally in an imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 11
Independent Claim
114 words
An apparatus comprising: a chassis; a removable enclosure extending around said chassis; and at least one manually actuable latch attached to one of said chassis and enclosure and releasably connectable to the other of said chassis and enclosure, said at least one manually actuable latch comprising: a fixed end fixed to said one of said chassis and enclosure, a movable end opposite said fixed end and releasably connectable to said other of said chassis and enclosure, and at least three flexible cantilevered arms interconnecting said fixed end and said movable end for constraining said movable end to move translationally in an imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 12
Independent Claim
113 words
An apparatus comprising: a chassis; a removable enclosure extending around said chassis; and at least one manually actuable latch attached to the enclosure and releasably connectable to the chassis, said at least one manually actuable latch comprising: a fixed end fixed to the enclosure, a movable end opposite said fixed end and releasably connectable to the chassis, said movable end having a locking tab for releasably engaging said chassis and a manually actuable release lever, and at least two flexible cantilevered arms interconnecting said fixed end and said movable end for constraining said movable end to move translationally in an imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 13
Independent Claim
113 words
An apparatus comprising: a chassis; a removable enclosure extending around said chassis; and at least one manually actuable latch attached to the enclosure and releasably connectable to the chassis, said at least one manually actuable latch comprising: a fixed end fixed to the enclosure, a movable end opposite said fixed end and releasably connectable to the chassis, said movable end having a locking tab for releasably engaging said chassis and a manually actuable release lever, and at least two flexible cantilevered arms interconnecting said fixed end and said movable end for constraining said movable end to move translationally in an imaginary plane passing through said fixed and movable ends and said cantilevered arms.
Claim 14
Dependent Claim
32 words
The apparatus of claim 10 wherein said fixed end is fixed to an inner surface of said enclosure, and said manually actuable release lever projects through an opening formed in said enclosure.
Claim 15
Dependent Claim
28 words
