Extension table
An extension table ( 2 ) comprises a plurality of extension rails ( 4, 6 ) along the table ( 2 ) for adjusting a dimension of the table ( 2 ), wherein an extension rail ( 4 ) of the plurality of extension rails ( 4, 6 ) comprises, laterally disposed relative to each other, a middle part ( 4 b ); a first outer part ( 4 a ) connected to a first section ( 10 ) of the table ( 2 ) and slidable relative to the middle part ( 4 b ), a second outer part ( 4 c ) connected to a second section ( 12 ) of the table ( 2 ) and slidable relative to the middle part ( 4 b ), wherein the middle part ( 4 b ), the first outer part ( 4 a ), and the second outer part ( 4 c ) of the extension rail ( 4 ) each comprises an identically designed profile ( 106 ).
1 . An extension table comprising a plurality of extension rails along said table for adjusting a dimension of said table, wherein each of said plurality of extension rails comprises:
one or more middle parts;
a first outer part fixed to a first section of said table and slidable relative to said one or more middle parts;
a second outer part fixed to a second section of said table and slidable relative to said one or more middle parts;
wherein each of said one or more middle parts, said first outer part, and said second outer part of said extension rail are laterally disposed relative to each other and have an identical profile,
wherein said profile defines a main space and a wall, and wherein the wall extends along a top of the main space, a bottom of the main space, and a side of the main space,
wherein said profile defines a closed tubular reinforcing section located above or below the main space,
wherein said profile of said first outer part and said profile of said one or more middle parts contains a sliding member located within the main space, and the main space comprising an opening in a direction away from the wall extending along a side of the main space,
wherein the opening of each profile faces in a same direction, and
wherein each of said sliding member is fixed to said profile wall of an adjacent profile through the opening of the main space in which the sliding member is located.
2 . The extension table of claim 1 , wherein said profile is made from bent sheet metal.
3 . The extension table of claim 1 , wherein said closed tubular structurally reinforcing section is located above said space for containing the respective sliding member.
4 . The extension table of claim 1 , wherein said first section of said table is fixed to said first outer part through said tubular structurally reinforcing section of said profile of said first outer part and said second section of said table is fixed to said second outer part through said tubular structurally reinforcing section of said profile of said second outer part.
5 . The extension table of claim 1 , wherein said profile comprises, on the same lateral side on which said space is open, a pair of opposing vertical protrusions for keeping said sliding member in said space.
6 . The extension table of claim 1 , wherein said profile comprising a plurality of middle parts, wherein each middle part is slidable with respect to an adjacent middle part.
7 . The extension table of claim 1 , wherein the closed tubular reinforcing section has a square cross section.
