Furniture piece with adjustable worksurface

A furniture piece comprising:

• a worksurface;
• a support frame having a first end, a second end, and an upper surface, the upper surface defining a horizontal plane;
• a linkage for coupling the support frame to the worksurface, wherein the linkage comprises a first arm rotationally coupled to both the support frame and the worksurface, and a second arm rotationally coupled to both the support frame and the worksurface, wherein the first arm is longer than the second arm;
• wherein the linkage is configured to permit movement of the worksurface between a first position wherein the worksurface is substantially parallel to the horizontal plane and a second position wherein the worksurface is located at an angle to the horizontal plane;
• and
• a first pair of legs extending downwardly from the first end of the support frame and a second pair of legs extending downwardly from the second end of the support frame,
• wherein upper ends of the legs in each of the first and second pair of legs are spaced apart from each other by at least 300 mm,
• wherein the linkage further comprises a lockout system for restraining the worksurface in the second position, the lockout system comprising:
• a lockout arm having a first end pivotally coupled to a central portion of the first arm and a second end having a guide protrusion;
• and
• a lockout arm guide positioned in an upper end frame member secured to the worksurface, the lockout arm guide defining a path for the guide protrusion between a first path end and a second path end, the second path end being configured such that the guide protrusion may be releasably retained at the second path end;
• wherein, when the worksurface is in the second position and the guide protrusion is retained at the second path end, the lockout arm prevents the first arm from rotating relative to the upper end frame member, and
• wherein the furniture piece further comprises a latching system for restraining the worksurface in the first position, the latching system comprising:
• a latching bar positioned in a latching bar recess of the upper end frame member, the latching bar having at least one latching protrusion that projects from a lower surface of the upper end frame member;
• and
• at least one latching recess provided in an upper surface of a lower end frame member, wherein, when the worksurface is in the first position, the at least one latching protrusion is received in the at least one latching recess;
• wherein the latching bar is configured to move within the latching bar recess between:
• a latched position in which, when the worksurface is in the first position, the at least one latching protrusion and the at least one latching recess cooperatively retain the worksurface in the first position, and
• an unlatched position.
