Definitions

  • the present invention relates to a height-adjustable table.
  • the invention is preferably used in tables for domestic furniture, such as kitchen or living-room tables.
  • the invention can be applied preferably to models of tables that have a single central leg with a floor stand.
  • Such tables have a telescopic central leg, inside which a gas cylinder is provided that can be actuated by a lever. Such a table is described in DE 39 38 496.
  • the aim of the present invention is to provide a height-adjustable table that can be adjusted easily.
  • an object of the present invention is to provide a height-adjustable table provided with reversible locking means that are easy to use.
  • Another object of the present invention is to provide a height-adjustable table that allows to contrast effectively the impulsive thrust of gas cylinders.
  • Another object of the present invention is to provide a height-adjustable table that can be manufactured with known systems and technologies.
  • a height-adjustable table comprising a top supported by at least one leg that is provided with a floor stand and can be extended telescopically, and means for reversible locking of the extension of said at least one leg, said at least one leg comprising a first outer element that is telescopically coupled to a second element arranged inside it, said table being characterized in that said reversible locking means comprise a first jaw and a second jaw that act, during locking, on mutually opposite parts of a same convex portion of said second inner element, said first jaw being connected, by means of a threaded coupling, to a pivot that is rigidly coupled to the hub of an actuation handwheel that is external with respect to said first outer element, said second jaw being arranged between said hub and said first jaw, said second jaw being movable substantially parallel to the axis of said pivot, said pivot drawing, during the locking step, said first jaw onto said second inner element, said second jaw being
  • a height-adjustable table according to the invention is generally designated by the reference numeral 10.
  • the table 10 comprises a top 11, which in this embodiment is preferably circular and is supported by a single central leg 12.
  • Such leg 12 can extend telescopically.
  • the table 10 further comprises means 13, described in greater detail hereinafter, for reversibly locking the extension of the central leg 12.
  • the leg 12 is constituted by a first outer element 15 that is telescopically coupled to a second element 16 that is arranged inside it.
  • the first outer element 15 is a cylinder provided with a through hole 17, which in this embodiment is eccentric.
  • the second inner element 16 constituted by a tubular body 16a, is arranged slidingly in the through hole 17.
  • the first outer element 15 is partially inserted in the upper opening of a hollow post 18 that is arranged vertically and constitutes the end structure by means of which the leg rests on the floor.
  • Such hollow post 18 has a circular floor stand 19 whose maximum width is greater than the maximum width of the post.
  • the tubular body 16a can move with respect to the first outer element 15, which does not move with respect to the floor.
  • the reversible locking means 13 comprise a first jaw 20 and a second jaw 21, which act during locking on mutually opposite parts 22 and 23 of a same cylindrical convex portion of the tubular body 16a.
  • the mutually opposite convex parts correspond to portions of cylindrical surfaces that are mutually opposite with respect to a common diametrical line of the tubular body 16a.
  • Such jaws 20 and 21 are slidingly accommodated inside a cylindrical seat 13a that is formed at right angles to the tubular body 16a inside the outer element 15 and intersects the through hole 17, thus forming an opening for connection to the through hole and therefore allowing the jaws to act on the tubular body 16a.
  • the jaws 20 and 21 are constituted respectively by a first cylindrical bush 24 and a second cylindrical bush 25, both of which have a portion, designated by the reference numerals 24a and 25a respectively, that is shaped complementarily to the contour of a corresponding one of the mutually opposite parts 22 and 23.
  • the first jaw 20 is connected, by way of a threaded coupling, to a pivot 30 that is rigidly coupled to the hub 31 of an actuation hand wheel 32 that is external with respect to the first outer element 15.
  • the pivot 30 passes through the second bush 25, while the first bush is internally threaded complementarily to a thread 33 provided at the end of the pivot 30.
  • the tubular body 16a is also partially contained inside the post 18; a gas cylinder is associated with the tubular body 16a and can be actuated by a valve that is associated by means of kinematic systems with an actuation lever 35 that is arranged below the top 11.
  • Such lever 35 cantilevers out from an end body 36 of the tubular body 16a that acts as a support for the top 11.
  • gas cylinder and the valve with the corresponding kinematic systems are not shown in the figures for the sake of graphic clarity, since they are in any case components that are widely used in the current art and are therefore of a known type.
  • the second bush 25 is internally threaded complementarily to a second thread that is substantially opposite with respect to the first thread 33 and is provided on a corresponding portion of the pivot 30.
  • both bushes are subjected to a translational motion by means of the rotary motion of the pivot.
  • the handwheel 32 is turned, thus making the jaws 20 and 21 move mutually closer until they clamp onto the tubular body 16a, thus contrasting both the axial thrust and any rotation of the tubular body 16a.
  • the present invention provides a height-adjustable table that can be used easily and is provided with reversible locking means whose operation is intuitive and effective.
  • the materials employed may be any according to requirements and to the state of the art.
