Definitions

  • the innovation relates to a height-adjustable table, in particular a single-column table with a table top, which is assigned telescopic tube parts, which can be moved against each other by a lifting device provided with a blocking device, the blocking device being actuated via a manually operated trigger device.
  • Height-adjustable tables of this type (but also height-adjustable chairs) are known, in which spring arrangements with weight compensation or so-called gas springs serve as energy stores in order to be able to carry out the desired height adjustment.
  • Blocking devices serve to secure the altitude attained in that the force effect of the lifting device is blocked.
  • a lever is provided as the triggering device, which is pivotally mounted below the table top or below the seat surface and with one end e.g. presses on an actuating pin of a valve when the lever is gripped by hand at the other end.
  • the innovation is based on the task of avoiding this disadvantage.
  • the triggering device is provided with a switch button arranged in the table surface.
  • the switch button is designed as a bolt which can be displaced in a hole in the table top and which is operatively connected to the blocking device of the lifting device arranged below the table top. This configuration makes it possible in a very simple manner to fall back on known lifting devices which contain their blocking devices and the release devices for this purpose.
  • a gas spring consisting of a piston / cylinder unit is provided as the lifting device and is equipped with a blocking valve serving as a blocking device, the pin leading downward through the table top can directly actuate a release pin of this blocking valve.
  • the upper end face of the bolt is in alignment with the table surface when not actuated.
  • the smooth, continuous table surface can be maintained.
  • the diameter of the bolt is advantageously adjusted approximately to the diameter of the cylinder of the gas spring, so that its axis is aligned with the axis of the gas spring and with a release pin of the blocking valve which is arranged on the gas spring axis and is pressed by spring force against the bolt.
  • the cylinder of the gas spring is firmly connected to the tubular part connected to the table top and the piston rod to the tubular part fixed to the foot of the table.
  • the bolt protrudes into the upper part of the tube part connected to the table top. It can be guided in a socket arranged in the table top and can be provided with a stop which rests on the underside of the socket. The aligned position of its front side on the table surface can be secured regardless of the position of the trigger pin.
  • the height-adjustable table (1) has a table top (2) which is held on a central base (3).
  • the base (3) consists of a plate-like base (4) which can be set up on the floor and which is firmly connected to a tubular stand sleeve (5).
  • the stand sleeve (5) is provided with a sliding bush (6), in which in turn a sliding tube (7) is guided, into which a bushing (8) is firmly inserted at the upper end, which has a flange (9) on the upper edge of the Slide tube (7) rests, and is firmly screwed to the table top (2).
  • the cylinder (12) of a gas spring known per se is inserted into the sliding tube (7) via two retaining rings (10, 11) and is thus firmly connected to the sliding tube (7).
  • the piston rod (13) of the gas spring protrudes from the bottom of its cylinder (12), and is fixed to the Base (4) and the standpipe (5) connected. If the gas spring therefore comes into action, the piston rod (13) is pushed out of the cylinder (12) at the bottom. As a result, the sliding tube (7), and with it the table top (2), can be shifted up to the end position shown in FIG. 2.
  • the gas spring consisting of the cylinder (12) and the piston rod (13) is provided in its interior in a known manner with a blocking valve, which further displaces the piston rod ( 13) connected but not shown piston inside the cylinder (12) prevented.
  • This blocking valve has a release pin (14) which protrudes upwards from the end of the cylinder (12) facing away from the piston rod (13) and is held in this protruding position by a spring (also not shown).
  • the trigger pin (14) is screwed with a thread into a corresponding thread (15) of a cylindrical bolt (16), the diameter of which is adapted to the inside diameter of the bush (8) so that the bolt (16) easily axially within the bush Can move the axis (17) of the base (3).
  • the bolt (16) is aligned with its upper end face (16a) with the upper side (2a) of the table top, and with this end face (16a) it serves as a switch button for triggering the blocking valve which is arranged inside the cylinder (12) of the gas spring is.
  • the blocking valve is released when an operator presses the end face (16a).
  • the bolt (16) is then moved downward and presses the release pin (14) into the interior of the cylinder (12).
  • the piston rod (13) is then pushed out of the cylinder (12) under the internal pressure of the gas spring. It can be locked in any position via the blocking valve if no longer is pressed onto the end face (16a) of the bolt (16), so that it again assumes the end position shown in FIG. 1 (and FIG. 2) which aligns its end face (16a) with the surface (2a) of the table top (2).
  • the diameter of the bolt (16) is selected to be somewhat larger than the diameter of the cylinder (12).
  • the bolt (16) protrudes with its upper end through a hole (18) in the table top (2). Due to the selected arrangement, it can be guided inwards in the flange bushing which is anyway necessary for fastening the table top (2) to the sliding tube (7) in order to actuate the release pin (14) located there. This results in a compact overall arrangement aligned with the axis (17).
  • the arrangement of the actuating end face (16a) in the middle of the table top (2) - with the selected single-column version - also has the advantage that an aesthetic picture of the table surface can be achieved.
  • the bolt (16) can be provided, at least on its upper side (16a), with a veneer that corresponds to the furner of the table top (2).
  • a veneer that corresponds to the furner of the table top (2).
  • it can also be adapted to other materials. Optical deposition of the surface (16a) by deliberately choosing other materials is also possible.
  • the bolt (16) is provided in the region of its underside with a locking ring (19) which acts as a stop and, in the position of FIGS. 1 and 2, bears against the underside of the bushing (8).
  • This stop can be designed and arranged so that the upper end face (16a) of the bolt (16) is always perfectly aligned with the table surface (2a).
