Abstract
Abstract An article of furniture used to support a computer terminal or a similar object having means to continuously adjust in a stepless fashion the table top height through the operation of a single operating lever located just beneath the table top which can be operated from a seated or standing position. Swinging the operating lever in one direction in the horizontal plane releases an adjustable length gas spring controlling table top height, allowing for the raising or lowering of the table top which is followed by the return of the operating lever to its original position which locks gas spring at its new length and rigidly locks the table top at its adjusted height.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
368 words
A table having a continuously adjustable table top comprising: A. a table top; B. a frame; C. a lockable gas spring; D. a pair slides, each slide of said pair of slides having a long slideable member and a fixed member; E. a cantilevered support rigidly fastened to said table top, said cantilevered support being a U-shaped member comprising: 1. a left arm; 2. a back panel; and 3. a right arm; said back panel having a length less than but approximately equal to the width of said table top, and wherein said long slideable member of a first of said pair of slides is fastened vertically to the rear edge of said left arm and said long slideable member of a second of said pair of slides is fastened vertically to the rear edge of said right arm and wherein each of said fixed members of said pair of slides is fastened vertically to said frame; F. a lower spring bracket fastened to said frame and to a lower end of said lockable gas spring, said lower spring bracket for supporting said lockable gas spring, said cantilevered support, said table top and any article placed on said table top; G. an upper spring bracket fastened to the underside of said table top and to an upper end of said lockable gas spring, said upper spring bracket for bearing the upward force of said lockable gas spring against the underside of said table top, and wherein said lower spring bracket is fastened to said frame approximately midway the lateral distance between said fixed members of said pair of slides and wherein said upper spring bracket is fastened to the underside of said table top approximately midway the lateral distance between said long slideable members of said pair of slides thereby aligning said lockable gas spring vertically in a plane perpendicular to said back panel; and H. an unlocking means connected to said lockable gas spring, said unlocking means for controlling the length of said lockable gas spring when displaced to a first position allowing the lengthwise adjustment of said lockable gas spring and when displaced to a second position locking said lockable gas spring at its adjusted length.
Claim 2
Dependent Claim
368 words
A table having a continuously adjustable table top comprising: A. a table top; B. a frame; C. a lockable gas spring; D. a pair slides, each slide of said pair of slides having a long slideable member and a fixed member; E. a cantilevered support rigidly fastened to said table top, said cantilevered support being a U-shaped member comprising: 1. a left arm; 2. a back panel; and 3. a right arm; said back panel having a length less than but approximately equal to the width of said table top, and wherein said long slideable member of a first of said pair of slides is fastened vertically to the rear edge of said left arm and said long slideable member of a second of said pair of slides is fastened vertically to the rear edge of said right arm and wherein each of said fixed members of said pair of slides is fastened vertically to said frame; F. a lower spring bracket fastened to said frame and to a lower end of said lockable gas spring, said lower spring bracket for supporting said lockable gas spring, said cantilevered support, said table top and any article placed on said table top; G. an upper spring bracket fastened to the underside of said table top and to an upper end of said lockable gas spring, said upper spring bracket for bearing the upward force of said lockable gas spring against the underside of said table top, and wherein said lower spring bracket is fastened to said frame approximately midway the lateral distance between said fixed members of said pair of slides and wherein said upper spring bracket is fastened to the underside of said table top approximately midway the lateral distance between said long slideable members of said pair of slides thereby aligning said lockable gas spring vertically in a plane perpendicular to said back panel; and H. an unlocking means connected to said lockable gas spring, said unlocking means for controlling the length of said lockable gas spring when displaced to a first position allowing the lengthwise adjustment of said lockable gas spring and when displaced to a second position locking said lockable gas spring at its adjusted length.
Claim 3
Dependent Claim
13 words
A table as in claim 1 wherein said frame is a vertical wall.
Claim 4
Dependent Claim
103 words
A table as in claim 1 wherein said frame comprises: A. a rear panel assembly; and B. a pair of side panel assemblies, each side of said pair of side panel assemblies connected to one end of said rear panel assembly such that rear panel assembly is supported in a vertical plane with said pair of side panel assemblies extending forward perpendicular to said rear panel assembly, a first side of said pair of side panel assemblies being parallel to a second side of said pair of side panel assemblies and wherein said lower spring bracket is fastened to said rear panel assembly.
Claim 5
Dependent Claim
17 words
A table as in claim 3 wherein said fixed members are fastened to said rear panel assembly.
Claim 6
Dependent Claim
33 words
A table as in claim 3 wherein a first of said fixed members is fastened to said first side and wherein a second of said fixed members is fastened to said second side.
Claim 7
Dependent Claim
74 words
A table as in claim 2 wherein said upper spring bracket is mounted on the underside of said table top at a distance from a rear edge of said table top such that said upper end of said lockable gas spring will be at a distance from said rear edge of said table top such that it is forward of a vertical center line of said long slideable members of said pair of slides.
Claim 8
Dependent Claim
49 words
A table as in claim 6 wherein said lower end of said lockable gas spring is fastened to said lower spring bracket at a distance from said rear panel assembly such that said lockable gas spring will be aligned vertically in a plane parallel to side rear panel assembly.
Claim 9
Dependent Claim
151 words
The table as in claim 7 wherein said lockable gas spring comprises an outer tube and a piston rod and said lockable gas spring is unlocked by rotating said outer tube relative to said piston rod and wherein said locking means comprises a lever at the upper end of said outer tube extending perpendicular to said outer tube and a valve activated by the rotation of said outer tube relative to said piston rod, the lower end of said piston rod being fixed to said lower spring bracket thereby preventing the rotation or axial displacement of said piston rod relative to said lower spring bracket, the upper end of said outer tube being fastened to said upper spring bracket in a manner that permits the rotation of said outer tube relative to said upper spring bracket but inhibits the axial displacement of said outer tube relative to said upper spring bracket.
Claim 10
Dependent Claim
89 words
The table of claim 8 wherein extension force of said lockable gas spring is slightly greater than the combined weight of that portion of said table which is displaced in the vertical direction when the height is adjusted and the weight of an article to be supported by said table, thereby allowing said lockable gas spring to counterbalance the displacement weight and permitting the table top to raise when said lockable gas spring is unlocked and yet permitting an operator to lower said table top by pressing downward thereon.
Claim 11
Dependent Claim
15 words
The table as in claim 9 wherein said lockable gas spring is damped on extension.
Claim 12
Dependent Claim
18 words
A table as in claim 1 wherein said pair of slides is a pair of ball bearing slides.
