Adjustable work surface

A height-adjustable work surface assembly comprising:

• a movable work surface;
• a frame extending from beneath the work surface in order to provide support for the work surface, the frame having a sleeve directed downward from beneath the work surface;
• a leg adjustably received within the sleeve of the frame, the leg having a cavity located therein;
• a movable rack having a series of outwardly extending teeth is positioned within the cavity, an end of the rack having an angled surface;
• an interlocking block having teeth opposing the rack in order to mate with the teeth of the rack at a given position, the block being positioned adjacent the rack;
• a wedge slidably engaged with the end of the rack, the angled surface of the rack corresponding to an angled upper surface of the wedge;
• a first fastening mechanism extending through the sleeve and the leg, and movably fastened to the block in order to secure the block in a given position against the rack;
• and
• a second fastening mechanism extending through the sleeve and the leg and movably fastened to the wedge in order to secure the wedge in a given position against the end of the rack;
• whereby the work surface height may be adjusted by the relative positioning of the leg within the sleeve of the frame as determined by the relative positioning of the block along the length of the rack and the wedge against the end of the rack.

A height-adjustable work surface assembly comprising:

• a moveable work surface;
• a frame extending from beneath the work surface in order to provide support for the work surface, the frame having a sleeve directed downward from beneath the work surface, the sleeve having an aperture and a slot extending thereacross, the aperture being located above the slot;
• a leg adjustably received within the sleeve of the frame, the leg having a cavity located therein and a slot extending along an upper portion of the first leg and through the cavity, the slot being in communication with the aperture within the sleeve of the frame;
• a movable rack having a series of outwardly extending teeth is positioned within the cavity, the rack having a centrally located slot extending therein, the slot being in communication with the slot of the leg and the aperture of the first sleeve, the lower end of the rack having an angled surface;
• an interlocking block that mates with the teeth of the rack, the block having an aperture that is in communication with the slots of the rack and the leg and the first aperture of the sleeve;
• a wedge slidably engaged with the end of the rack, the wedge having an aperture in communication with the slot of the sleeve and having an angled upper surface positioned against the lower end of the rack, the angled surface of the rack corresponding to the angled surface of the wedge;
• and
• first and second fastening mechanisms received within the first and second apertures of the frame, respectively, the first fastening mechanism removably fastened through the first aperture of the frame, the slots of the leg and the rack, to the aperture of the interlocking block, the second fastening mechanism removably fastened through the slot of the frame to the aperture within the wedge whereby the work surface height may be adjusted by the relative positioning of the leg within the sleeve of the frame as determined by the relative positioning of the block along the length of the rack and the wedge against the lower end of the rack.

A horizontally-adjustable work surface assembly comprising:

• a work surface having a top surface and a bottom surface;
• a frame extending from beneath the work surface in order to provide support for the work surface, the frame including at least one leg attached thereto;
• a first rail attached to the frame, the first rail including an aperture on an end thereof;
• a second rail attached to the work surface, the first rail and the second rail being movable relative to one another;
• and
• a lock member attached to the bottom surface of the work surface adjacent an end of the work surface and directly adjacent an end of the second rail, the lock comprising a body and a latch member, the latch member adapted to be received within the aperture of the first rail.
