TABLE LIFTER EQUIPPED WITH CONCURRENTLY LINKING ASCENT AND DESCENT MECHANISM

摘要

PURPOSE:To enable a table to be vertically moved upward by making the right and left links move simultaneously at the same speed through a linking member as well as making one end of a link for ascent and descent actuate untouchablly with a lower surface of the table and the upper part of a base case, so as to make a link mechanism conduct its opening and closing motion. CONSTITUTION:A couple of joining bodies 9 are fixed to the fixed side end in the right and left direction on the upper surface 3a of the base 3 of a table lifter 1, and four supporting members 17 are set on the moving side in two lines in the right and left directions at a fixed interval. The joining body 9 and the supporting member 17 are fixed to the lower surface 5a of a table 5 by making them face to a position set on the upper surface 3a of the base 3. A lower sliding axis 27 and an upper sliding axis 29 are set on the supporting member 17, and further a joining member 31 in lateral direction is set. When a pushing force is transmitted to an inner link 49 by a hydraulic cylinder 57, the moving side slides on the upper sliding axis 29 through a sliding body 33 to give the table 5 an ascending force. Then, as one end of the inner link 49 is put in connection by the joining member 31, the sliding can be performed simultaneously on the right and left links at the same speed to enable the ascending force to be given in laterally balance state.
