| مستخلص: | The present invention discloses a multi-stage height-adjustable table, including an operation control member and a table leg assembly arranged on the table board. The inner leg of the table leg assembly is sleeved in the hollow outer leg, and the inner leg has a containing groove for accommodating the elastic element. Operate the control element and move the table board according to the manipulation to drive the operation of the actuation unit of the operating wire linked to the table leg assembly. When the wire is operated on the wire, the inner leg can be lifted and lowered in the hollow outer leg. Then manipulate the operating control to make the operating wire in the pay-off state, and the actuation unit will abut one of the positioning parts of the inner leg post to form a position-fixed state, and adjust the height of the table accordingly. |

| Claim: | 2. The height-adjustable table according to claim 1 , wherein the actuation unit is arranged on a side of the hollow outer leg, and the actuation unit includes a limiting member and an adjusting member, the limiting member has a limiting groove, an end of the adjusting member is connected to the limiting member and another end of the adjusting member has an abutting portion for abutting and fixing on one of the positioning positions of the positioning portions, the adjusting member further has a through hole corresponding to the limiting groove, and the operating wire passes through the limiting groove to the through hole to form the connection. |
| Claim: | 3. The height-adjustable table according to claim 1 , wherein the operation control member has a movable pressing plate, and the releasing action of the movable pressing plate controls the actuation unit to abut against one of the positioning portions at one of the positioning positions to form the position-fixed state, the locking action of the movable pressing plate controls the actuation unit to move away from the positioning portions, so the inner leg is positioned within the hollow outer leg to adjust the height of the table board accordingly. |
| Claim: | 4. The height-adjustable table according to claim 1 , wherein the elastic element is a clockwork spring. |
| Claim: | 5. The height-adjustable table according to claim 1 , wherein at least one inner side of the hollow outer leg is arranged with an outer sliding rail, at least one outer side of the inner leg is arranged with an inner sliding rail, and the inner sliding rail is correspondingly assembled in the outer sliding rail, and the inner sliding rail slides relative to the outer sliding rail within the outer sliding rail. |
| Claim: | 6. The height-adjustable table according to claim 1 , wherein number of the operation wires used is the same as number of the table leg assemblies when the number of table leg assemblies are more than two, and the table leg assemblies are both connected to one of the operating control members at the same time, the operating control members simultaneously control the actuation unit to abut against one of the positioning portions at one of the positioning positions to form a stable state to adjust the height of the table board accordingly. |
| Claim: | 7. The height-adjustable table according to claim 1 , wherein number of the operating wire and number of the operation control members used are the same as number of the table leg assemblies, and the operation control members respectively control the actuation unit to abut against one of the positioning portions at one of the positioning positions to form a stable state to adjust the height of the table board accordingly. |
| Claim: | 8. The height-adjustable table according to claim 1 , wherein the operating wire is steel wire. |
| Claim: | 9. The height-adjustable table according to claim 8 , wherein the plurality of positioning portions are formed by guide racks, or the plurality of positioning portions are plurality of guide tooth. |
| Claim: | 10. A height-adjustable table, comprising: a table board; at least one operation control member arranged on a surface of the table board; at least one table leg assembly arranged on the table board, the table leg assembly including a hollow outer leg, an inner leg, an actuation unit and an elastic element; the inner leg being sleeved in the hollow outer leg and the inner leg having a housing for accommodating the elastic element, the inner leg having a plurality of positioning portions on the side, and the actuation unit for abutting against the side of the inner leg and being located at one of the positioning positions of the plurality of positioning portions; and at least one operation wire that connected the operation control member and the actuation unit, the table board being moved according to the manipulation of the operation control member by driving the operation wire to gear the operation of the actuation unit; the actuation unit being away from the positioning portions when the operating wire being pulled, so the inner leg being lifted up within the hollow outer leg; manipulating the operating control member so the actuation unit being abutted against the actuation position of one of the positioning portions to form a position-fixed state when the operating wire being loosen, and the height of the table board being adjusted accordingly; wherein the actuation unit is arranged on a side of the hollow outer leg, and the actuation unit includes a limiting member and an adjusting member, the limiting member has a limiting groove, an end of the adjusting member is connected to the limiting member and another end of the adjusting member has an abutting portion for abutting and fixing on one of the positioning positions of the positioning portions, the adjusting member further has a through hole corresponding to the limiting groove, and the operating wire passes through the limiting groove to the through hole to form the connection. |
| Claim: | 11. A height-adjustable table, comprising: a table board; at least one operation control member arranged on a surface of the table board; at least one table leg assembly arranged on the table board, the table leg assembly including a hollow outer leg, an inner leg, an actuation unit and an elastic element; the inner leg being sleeved in the hollow outer leg and the inner leg having a housing for accommodating the elastic element, the inner leg having a plurality of positioning portions on the side, and the actuation unit for abutting against the side of the inner leg and being located at one of the positioning positions of the plurality of positioning portions; and at least one operation wire that connected the operation control member and the actuation unit, the table board being moved according to the manipulation of the operation control member by driving the operation wire to gear the operation of the actuation unit; the actuation unit being away from the positioning portions when the operating wire being pulled, so the inner leg being lifted up within the hollow outer leg; manipulating the operating control member so the actuation unit being abutted against the actuation position of one of the positioning portions to form a position-fixed state when the operating wire being loosen, and the height of the table board being adjusted accordingly; wherein the operation control member has a movable pressing plate, and the releasing action of the movable pressing plate controls the actuation unit to abut against one of the positioning portions at one of the positioning positions to form the position-fixed state, the locking action of the movable pressing plate controls the actuation unit to move away from the positioning portions, so the inner leg is positioned within the hollow outer leg to adjust the height of the table board accordingly. |
