Abstract
Abstract A pair of rectangular sub-frames are joined together in spaced relationship forming a free standing central core module. The vertical members of each subframe include latch mechanisms extending along their length to support components in cantilevered fashion. The lower portion of the core is enclosed by panels which enclose electrical and fluid accessories leading to outlets in the panels. At least a portion of the front and rear panels are removable to permit free access to the interior of the lower portion. The entire system is quickly subject to dismantling and one core module can be quickly connected to another in tandem forming a multiple system.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
176 words
A laboratory module system having fluid and electrical accessories and outlets incorporated therewith comprising, in combination: a free standing central frame comprised of at least one pair of first and second rectangular sub-frames interconnected to each other in spaced relationship, each of said sub-frames having horizontal top and bottom tube-like members connected to vertical end tube-like members, one or more of said vertical members including latch means extending vertically the length thereof, said central frame having a lower enclosed portion and an upper exposed portion, said lower enclosed portion having vertical panel means and a horizontal shelf at the transition of said upper and lower portions, said shelf extending between said sub-frames, the fluid and electrical accessories and outlets being enclosed within said lower portion and having outlet means through at least one of said panel means or shelf, said vertical panel means having portions thereof detachable from said central frame permitting access to the interior of said lower portion of said central frame, and at least one laboratory components detachably latched to said latch means.
Claim 2
Dependent Claim
176 words
A laboratory module system having fluid and electrical accessories and outlets incorporated therewith comprising, in combination: a free standing central frame comprised of at least one pair of first and second rectangular sub-frames interconnected to each other in spaced relationship, each of said sub-frames having horizontal top and bottom tube-like members connected to vertical end tube-like members, one or more of said vertical members including latch means extending vertically the length thereof, said central frame having a lower enclosed portion and an upper exposed portion, said lower enclosed portion having vertical panel means and a horizontal shelf at the transition of said upper and lower portions, said shelf extending between said sub-frames, the fluid and electrical accessories and outlets being enclosed within said lower portion and having outlet means through at least one of said panel means or shelf, said vertical panel means having portions thereof detachable from said central frame permitting access to the interior of said lower portion of said central frame, and at least one laboratory components detachably latched to said latch means.
Claim 3
Dependent Claim
25 words

Claim 8
Dependent Claim
50 words
The combination according to claim 1 wherein said latch means extends along each lateral face of said vertical members, and said laboratory component extends laterally a distance greater than the spacing of said sub-frames, said component being cantilever supported by said latch means from either sub-frame in either lateral direction.
Claim 9
Dependent Claim
38 words
The combination according to claim 1 wherein said vertical panel means includes an upper portion extending the width of each central frame and affixed to said frame, and a lower portion, said lower portion comprising said detachable portion.
Claim 10
Dependent Claim
41 words
The combination according to claim 8 wherein said bottom tube-like members include an upstanding flange means and said detachable portions of said vertical panel means are seated on the upper surface of said bottom members and indexed against said flange means.
Claim 11
Dependent Claim
33 words
The combination according to claim 9 wherein said detachable vertical panel means includes a first latch portion engageable with said flange means and a second latch portion engageable with said vertical sub-frame members.
Claim 12
Dependent Claim
30 words
