Definitions

  • the present invention relates to an improved extensible leg designed in particular, but not exclusively, for tables.
  • the level from the floor to the top of a table used by a child is varied as a function of the child's growth in tallness, in order to prevent as far as possible that child's backbone may undergo malformations.
  • the length of table legs should be adjustable within a very wide range, for example of a round 15-20 cm, also on considering the average tallness of different populations.
  • the purpose of the present invention therefore is of fulfilling the above cited requirements by providing a leg for tables which, besides being easily extensible, additionally displays a sturdy structure and a valuable aesthetical appearance.
  • the extensible leg according to the present invention is generally indicated with (10) and is structurally formed by a tube (11) to an end of which a sleeve (12) is applied which is provided with an internal screw-thread (13) ( Figures 4 and 5).
  • Said sleeve (12) is integral with said tube (11).
  • the internal rod (14) and the external sleeve (16) are constrained to each other by means of a coupling means (17) constituted by a base (18) from which two concentric cylindrical portions (19) (the innermost portion) and (20) (the outermost portion), respectively, extend upwards.
  • the portion (19) is higher and is made integral with said rod (14) by means of a coupling of groove-rib type (21), (22).
  • the portion (20) is shorter, and is provided with grooves (23) inside which inner ribs (24) of the external sleeve (16) get engaged.
  • the sleeve (16) is made integral with the extending cylindrical portion (20) of the coupling means (17).
  • the reference numeral (28) indicates a scale applied to tube (11) from which the user can read the leg extension extent ( Figure 1).
  • the leg can be easily adjusted in height by rotating, in either directions, the external sleeve (16) -- consequently, the internal rod (14) -- which will cause the tube (11), which is linked to the rod (14) through the screw-threaded sleeve (12), to translate upwards or downwards.
  • the extension mechanism is of relatively cheap structure and extremely easy to assemble.
  • said extension mechanism is completely hindered to sight by the presence of the external sleeve (16) which, however, is not just a simple aesthetical component, but also performs a structural task, contributing to increase the strength of the overall mechanism.
