<p>PROBLEM TO BE SOLVED: To mass-produce desks with height-adjustable top plates by simple work at a low cost by enlarging withstanding load of telescopic legs and increasing design degree of freedom.SOLUTION: The desk is configured to adjust the height of a top plate 1 by changing the full length of telescopic legs 7. Each telescopic leg 7 includes: a stationary leg 2 fixed to the top plate 1 and having a cylinder part 4 with a lower-end opening; an extension leg 3 having a flange part 9 at a lower end of an insertion rod part 8 that is extractably inserted in the cylinder part 4; and an adjustment cylinder 10 in which the insertion rod part 8 is inserted. The height of the top plate 1 is adjusted by changing the full length of the telescopic legs 7 by the adjustment cylinders 10 to be inserted into the insertion rod parts 8.</p> |
