Abstract
A telescopic leg for supporting a table-top of a table, the 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 the telescopic leg includes: a plurality of leg members slidingly engaged with each other along the extension axis; the plurality of leg members including a first leg member terminating with the first end, suitable to rest on the floor or be fixed to a base, and a last leg member terminating with the second end and suitable to be fixed to the table-top; wherein the last leg member is an extruded tubular member internally defined by a tubular member inner surface.
Claims13
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 a 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 of leg members 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 of leg members 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, and a second longitudinal plane passing through the central axis and orthogonal to the first longitudinal plane;
- wherein an 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 an entire length of said tubular member projecting from said tubular member inner surface inwardly of the tubular member;
- and wherein
- said main bundle is completely arranged in said first tubular member half, avoiding to be arranged in the second tubular member half,
- wherein said main bundle of ribs is centered with respect to the second longitudinal plane in a specular way with respect to the second longitudinal plane, and the main bundle of ribs is arranged around the intersection between the first tubular member half and the second longitudinal plane;
- wherein the main bundle of ribs is formed by an odd number of parallel ribs, wherein a central rib of bundle of ribs is arranged along the second longitudinal plane;
- and
- wherein each rib of said main bundle of ribs comprises a longitudinal channel, configured for receiving and holding a securing screw in a longitudinal direction for securing the table-top of a table to said last leg member.
