A mechanism for dual-height tables, counters, or the like, in which the top lifts and pivots upward and outward on pairs of links attached to the top and to link housings attached to the table or counter base. Each pair of links comprises a pivot link and a locking link. The pivot link has holes at each end which ride on pins or the like attached to a bracket on the top and the pivot link housing on the bottom. The locking link is similarly arranged at the top, with a hole for a pin attached to a bracket. The bottom end of the locking link has an elongated slot, through which a pin is inserted to fasten the locking link to the locking link housing. When the top is in the lowered position, the pin is in the end of the slot closest to the end of the locking link. As the top is raised, both links pivot on the pins in the link housings. When the top has reached its most-forward pivot position, the locking link rests on a forward stop. The locking link is then slid downward into a locking pocket in its housing, the pin moving upward in the slot until it rests on the top of the slot and the top of the table is horizontal. At this point the top is rigidly supported and locked in the forward/upward position.

A mechanism for adjustably supporting a planar surface in a raised or lowered position over a support frame, comprising: a) a locking link housing attached to the support frame, having pivot pin means for pivotally holding the end of a link by passing through a slot therein, stop means for preventing a link pivoted on the pivot pin means from pivoting beyond a chosen vertical angle; and pocket means for holding a link against pivoting, located in the locking link housing relative to the pivot pin means such that when the link is pivoted on the pivot pin and is stopped by the stop means at the chosen vertical angle., the link is aligned with the pocket means; b) pivot link housing means for pivotally holding an end of a pivot link, attached to the support frame, having pivot pin means for pivotally holding the link in the pivot link housing by passing through a hole in said link and through said pivot link housing means; c) an elongated pivot link, having holes adjacent to each end thereof, one end of the pivot link being pivotally attached to the pivot link housing means by having the pivot pin means of the pivot link housing means pass through the hole therein, such that the pivot link is movable from a first lowered position to a second raised position by pivoting said link on said pivot pin means of the pivot link housing means; d) an elongated locking link, having a hole adjacent one end, and a slot adjacent the other end, the end of the locking link having the slot being pivotally and slideably attached to the locking link housing by having the pivot pin means of the locking link housing pass through the slot therein, such that the locking link is movable from a first lowered position to a second raised locked position by pivoting the link on the pivot pin when said pin is in the end of the slot nearest the end of the link until the locking link rests on the stop means of the locking link housing, then lowering the end of said link into the pocket means of the locking link housing by sliding said pivot pin through said slot until said pivot means rests on the opposite end of said slot; e) a first bracket means, pivotally attached to the pivot link by a pivot pin means passing through the hole in said pivot link adjacent to the end opposite the end attached to the pivot link housing, having means for attaching the first bracket means to the planar surface; f) a second bracket means, pivotally attached to the locking link by a pivot pin means passing through the hole in said locking link, having means for attaching the second bracket means to the planar surface; such that when the pivot link housing and locking link housing are attached to the support frame and the first and second brackets are attached to the planar surface, the planar surface is movable from a first, lower position to a second, higher position and locked in place in said higher position by pivoting the pivot link and locking link from their first position to their second position, then lowering the locking link into the pocket means of the locking link housing.
