Abstract
Abstract A vertically adjustable, retrofittable work station including a first pair of vertically oriented, spaced rails (5) having engaging teeth (10) protruding therefrom so as to be stationarily mounted on an existing wall panel (1) of a conventional work station, a second pair of vertically oriented rails (6) individually, slidably, interlockingly disposed in the first pair of rails (5), a pair of support brackets (3) having engaging teeth (17) protruding therefrom so as to be individually mounted on the second pair of rails (6), a work surfaces (4) supported by the support brackets (3), a pair of interconnecting channels (7, 8) for respectively interconnecting the first and second pairs of rails (5,6), and a drive mechanism coupled between the interconnecting channels to move the channels toward or away from each other so as to attendantly displace the work surface (4).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A vertically adjustable, work station adapted to be mounted to a wall panel, comprising: (a) a pair of horizontally spaced, vertically oriented support rails secured to said panel; (b) a work surface; (c) a pair of support brackets for supporting said work surface; (d) a first pair of elongate, vertically oriented, rails horizontally displaced from one another and adapted to be individually and stationarily mounted to the support rails; (e) a second pair of elongate, vertically oriented, rails individually slidably mounted to said first pair of rails; (f) means for individually mounting said support brackets and thus said work surface to said second pair of rails; (g) a first elongate, horizontally oriented, channel member interconnecting said first pair of rails; (h) a second elongate, horizontally oriented, channel members interconnecting said second pair of rails; and (i) drive means coupled between said first and second channel members for selectively displacing said channel members towards or away from each other to attendantly vertically displace the work surface.
Claim 2
Dependent Claim
165 words
A vertically adjustable, work station adapted to be mounted to a wall panel, comprising: (a) a pair of horizontally spaced, vertically oriented support rails secured to said panel; (b) a work surface; (c) a pair of support brackets for supporting said work surface; (d) a first pair of elongate, vertically oriented, rails horizontally displaced from one another and adapted to be individually and stationarily mounted to the support rails; (e) a second pair of elongate, vertically oriented, rails individually slidably mounted to said first pair of rails; (f) means for individually mounting said support brackets and thus said work surface to said second pair of rails; (g) a first elongate, horizontally oriented, channel member interconnecting said first pair of rails; (h) a second elongate, horizontally oriented, channel members interconnecting said second pair of rails; and (i) drive means coupled between said first and second channel members for selectively displacing said channel members towards or away from each other to attendantly vertically displace the work surface.
Claim 3
Dependent Claim
71 words
The work station of claim 1, wherein each of said support rails includes one of a plurality of slots and a plurality of teeth-like protrusions vertically disposed therealong and each of said first rails includes another of said plurality of slots and said plurality of teeth-like projections vertically disposed therealong wherein said protrusions are insertable into said slots to stationarily individually mount said first pair of rails to said support rails.
Claim 4
Dependent Claim
69 words
The work station of claim 1, wherein each of said second rails includes one of a plurality of slots and a plurality of teeth-like protrusions vertically disposed therealong and each of said support brackets includes another of said plurality of slots and said plurality of teeth-like projections vertically disposed therealong wherein said protrusions are insertable into said slots to stationarily individually mount said support brackets to said second rails.
Claim 5
Dependent Claim
84 words
The work station of claim 1, wherein said drive means comprises: an elongate vertically extending drive screw rotatably secured to one of said first and second channel members; a threaded nut fixedly secured to another of said first and second channel members, said drive screw being threadedly engaged with said nut; and mean for rotating said drive screw relative to said nut such that said drive screw and said nut move toward or away from one another to attendantly vertically displace the work surface.
Claim 6
Dependent Claim
46 words
The work station of claim 1, wherein each of said rails of said first and second pairs of rails are substantially C-shaped and wherein said second pair of rails are individually slidably interconnected to said first pair of rails with a substantially frictionless member interlocked therebetween.
Claim 7
Dependent Claim
31 words
The work station of claim 1, further comprising a slide support for providing support to said first and second channel members when said channel members are driven by said drive means.
Claim 8
Dependent Claim
111 words
The work station of claim 6, wherein said slide support comprises: a vertically oriented slide plate fixedly connected to one of said first and second channel members and having flanges on opposing sides thereof; a substantially frictionless member fixedly connected to each of said flanges; a vertically oriented bearing bracket fixedly connected to another of said first and second channel members and having receiving portions on opposing sides thereof, said frictionless members being individually slidable disposed in said receiving portions of said bearing bracket so as to distribute the torsional forces associated with said drive means such that said first and second members can be smoothly, vertically displaced from one another.
