A telescopic leg (1) for supporting a table-top (3) of a table, said leg (20) defining an extension axis (A), a first end (4) of the leg (1), and a second end (5) of the leg (1), opposite the first end (4), wherein the length of the leg (1) between the first end (4) and the second end (5) is adjustable between a minimum length and a maximum length, wherein said telescopic leg (1) comprises a plurality of leg members (10,20,30) slidingly engaged with each other along the extension axis (A); said plurality of leg members comprising a first leg member (10) terminating with said first end (4), suitable to rest on the floor or be fixed to a base, and a last leg member (30) terminating with said second end (5) and suitable to be fixed to said table-top (3); wherein said last leg member (30) is an extruded tubular member internally defined by a tubular member inner surface (81); said tubular member (30) defining a central axis (T) substantially parallel to said extension axis (A), and a first longitudinal plane (CI) passing through said central axis (T); wherein the intersection between said first longitudinal plane (CI) and the tubular member (30) defines a first tubular member half (30′) and a second tubular member half (30″); wherein said tubular member (30) comprises a main bundle (70) of longitudinal reinforcing ribs (71, 72, 73) extending throughout the entire length of said tubular member (30) projecting from said tubular member inner wall (81) inwardly (80) of the tubular member (30); and wherein said main bundle (70) is completely arranged in said first half of tubular member (30′). |

1. A telescopic leg for supporting a table-top of a table, said leg defining an extension axis, a first end of the leg, and a second end of the leg, opposite the first end, wherein the length of the leg between the first end and the second end is adjustable between a minimum length and a maximum length, wherein said telescopic leg comprises:
a plurality of leg members mutually slidingly engaged along the extension axis; said plurality comprising a first leg member ending with said first end, suitable to be rested or secured to a fixed surface or a base, and said plurality comprising a last leg member ending with said second end and suitable to be secured to said table-top; wherein said last leg member is an extruded tubular member internally defined by a tubular member inner surface; said tubular member defining a central axis substantially parallel to said extension axis, and a first longitudinal plane passing through said central axis; wherein the intersection between said first longitudinal plane and the tubular member defines a first tubular member half and a second tubular member half; wherein said tubular member comprises a main bundle of longitudinal reinforcing ribs extending throughout the entire length of said tubular member projecting from said tubular member inner wall inwardly of the tubular member; and wherein said main bundle is completely arranged in said first tubular member half. |
