Abstract
Abstract A table more specially in the form of desk has a desk frame (10) that has an oblique element (16) extending in an upward direction, in which there is an arrangement (44 and 59) for adjustment of the height of the top part (21) of the desk. This element (16) accommodates a sliding element (44) which at its top end bears a support member (17 and 18) for the top part (21) of the desk. The latter may be shifted in relation to the support member (17 and 18) and is connected with the desk frame (10) by an adjustment arrangement (23) so that when the top part (21) of the desk is adjusted in height the top part is kept from moving horizontally to any substantial extent in relation to the person using the desk.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A height adjustable table comprising: at least one side frame including a level element adapted to be placed on a floor and a hollow oblique element having an upper portion and connected to the level element to extend obliquely upwardly therefrom; a horizontal table top; at least one table top side support having an upper horizontal surface for supporting said horizontal table top thereon; height adjusting means including a rod connected to said table top side support and located within said hollow oblique element and means for moving said rod within said hollow oblique element to move said side support and table top supported thereon to a desired height relative to said side frame; means for securing said rod and thus said side support and table top at said desired height; and an adjusting device connecting said table top and said side frame for moving said table top laterally on the upper horizontal surface of said table top side support while said side support and table top are moved to said desired height with minimal lateral movement of said table top relative to the side frame.
Claim 2
Dependent Claim
186 words
A height adjustable table comprising: at least one side frame including a level element adapted to be placed on a floor and a hollow oblique element having an upper portion and connected to the level element to extend obliquely upwardly therefrom; a horizontal table top; at least one table top side support having an upper horizontal surface for supporting said horizontal table top thereon; height adjusting means including a rod connected to said table top side support and located within said hollow oblique element and means for moving said rod within said hollow oblique element to move said side support and table top supported thereon to a desired height relative to said side frame; means for securing said rod and thus said side support and table top at said desired height; and an adjusting device connecting said table top and said side frame for moving said table top laterally on the upper horizontal surface of said table top side support while said side support and table top are moved to said desired height with minimal lateral movement of said table top relative to the side frame.
Claim 3
Dependent Claim
47 words
A height adjustable table according to claim, 1 in which said adjusting device comprises at least one link having a first end pivotally connected to the oblique element and a second end pivotally connected to the table top to control said lateral movement of the table top.
Claim 4
Dependent Claim
38 words
A height adjustable table according to claim 2, in which said adjusting device further includes a projection attached to the table top to extend downwardly therefrom, said second end of the link being pivotally connected to the projection.
Claim 5
Dependent Claim
31 words
A height adjustable table according to claim 3, in which said adjusting device is covered by the table top side support so that the adjusting device is not seen from outside.
Claim 6
Dependent Claim
82 words
A height adjustable table according to claim 1, in which said height adjusting means further comprises a spring device connected between the rod and the side frame urging said rod upwardly to easily move the table top side support with the table top relative to the side frame when adjusting height of the table top, and said securing means comprises a locking device situated between the rod and the side frame to stop movement of the rod relative to the side frame.
Claim 7
Dependent Claim
49 words
A height adjustable table according to claim 5, in which said height adjusting means further includes at least two rollers rotationally connected to the rod, said rollers being spaced apart from each other within said hollow oblique member for sliding the rod along the inside of the oblique element.

Dependent Claim
71 words
A height adjustable table according to claim 6, in which said locking device comprises a plurality of notches formed on the rod, a detent situated adjacent and removably-engageable with the notches, and a driving rod connected to the detent whereby when the driving rod is actuated, the detent engaged with one of the notches disengages from the notch to thereby allow the side support and table top to move as desired.
Claim 9
Dependent Claim
33 words
A height adjustable table according to claim 7, further comprising a foot pedal connected to said driving rod for axially shifting said driving rod to engage and disengage said detent from said notches.
