Definitions

  • the invention relates to a lockable lifting device according to the preamble of claim 1 and a length-adjustable gas spring for such a lifting device according to the preamble of claim 11.
  • the cylindrical outer surface of the housing of the gas spring is guided directly in a guide bush connected to the guide tube.
  • the gas spring is therefore not only a load-bearing and length-adjustable element, but also a guiding and rotating element. Since the piston rod in the base plate of the guide tube is not only freely rotatable but also fastened radially with sufficient play, the gas spring can align itself according to any changing load directions of the seat surface or table top, so that there is no risk of jamming.
  • the seals surrounding the piston rod of the gas spring are not loaded on one side, so that the gas spring also does not leak and can therefore not function.
  • the gas spring is thus softly supported laterally relative to the tubular column, so that no jamming between the piston rod and the cylinder on the one hand and between the cylinder and the tubular column on the other hand can occur.
  • Blockable lifting devices of this type have long proven themselves in practice on a large scale.
  • the housing of the gas spring is attached to the underside of the chair seat or the table top by means of a clamping device comprising a cylindrical upper section of the housing of the gas spring, as described, for example, in DE-C-19 31 012 (corresponding to US Pat. No. 3,711,054) ) or from DE-A-28 36 666 (corresponding to US-A-4 283 033) is known. It is also known to provide a connection between the housing of the gas spring and the underside of the chair seat or the table top, the gas spring with a conical fastening section which is inserted under pressure in a suitably designed hub on the underside of the chair seat or the table top becomes.
  • This configuration has the advantage that the connection between the chair seat or table top and the lifting device can be produced very easily, which is particularly advantageous for the dispatch of such furniture in disassembled condition and its subsequent assembly at the dealer or end user.
  • a conical configuration of the fastening section is known from DE-U-70 19 918 (corresponding to US-A-3 790 119).
  • conical plug-in connections there is a risk that the fastening section and the corresponding hub will eat due to the constant load, i.e. can practically no longer be detached from one another, and in particular cannot be detached without the aid of tools by means of which the surface of the guide tube which can be displaced relative to the guide tube Gas spring housing has been damaged.
  • a chair with a telescopic lifting device which consists of a guide tube attached to a chair cross or the like and an inner telescopic tube attached to the seat.
  • a length-adjustable gas spring is arranged in the lifting device, the housing of which is received by the inner telescopic tube, while its piston rod is fastened to the bottom of the lower guide tube.
  • the housing of the gas spring rests with its upper edge against a stop sleeve which is permanently attached to the upper part of the inner telescopic tube which is fastened in the seat.
  • the housing is interlocked by pins.
  • Secured which engage in a corresponding annular recess in the upper end region of the housing of the gas spring.
  • the housing of the gas spring itself is arranged in a laterally oscillating manner in the inner telescopic tube.
  • the invention is therefore based on the object of designing a lifting device of the generic type while maintaining all advantageous properties with little effort so that the gas spring can be detached from the chair seat or the table top in a simple manner.
  • an additional tube is made part of the housing of the gas spring, which can be connected in a simple manner to the chair seat or the table top by means of a particularly conical fastening section with the corresponding fastening element, for example a conical hub.
  • a particularly conical fastening section with the corresponding fastening element, for example a conical hub.
  • the actual gas spring which therefore only requires a simple, cylindrical, untreated housing on its outer surface, is then pulled out of the additional tube after the one fastening element the bottom of which is loosened.
  • the housing and the tube are connected radially to one another, the housing and the tube together contribute to the lateral strength, that is to say the bending strength, of the entire lifting device.
  • the measures according to claim 2 which at the same time ensures that the lifting device can remain very slim.
  • the measures according to the invention likewise significantly increase the safety of the overall device.
  • the measures of claim 3 ensure that no punctiform pressures occur between the housing of the gas spring and the additional tube, which measures can be used at the same time according to claim 4 that a sliding body for actuating the actuating plunger is held.
  • a length-adjustable gas spring which can be used in a lockable lifting device according to the invention is protected in the embodiment according to the invention as an independent tradable good.
  • From DE-U-19 61 656 is a blockable lifting device for the stepless adjustment of chair seats or the like.
  • known which consists of two telescopically guided tubes, the lower guide tube is connected to a base frame, while the upper tube made in the guide tube is inextricably linked to a support plate arranged under the seat.
  • a length-adjustable gas spring is arranged, the upper end of which is screwed to the plate mentioned. Your piston rod is screwed to a bottom plate of the guide tube.
  • This configuration had been developed into the generic lifting device according to DE-C-19 31 012. Since there is not a fastening section of the gas spring itself or the like in the generic manner with the chair seat. can be connected, this known embodiment could not provide any suggestions with regard to the solution according to the invention.
  • the blockable lifting device shown in the drawing for stepless adjustment of seats or table tops has a lower guide tube 1, which is essentially cylindrical, but in its lower region has a downwardly conically tapering section 2, which is received in a corresponding hub 3 of a base frame 4 is used.
  • the guide tube 1 is provided near its lower end with a base plate 5 which has an opening 7 which is concentric with the central longitudinal axis 6 of the entire lifting device and thus also the guide tube 1.
  • a length-adjustable, hydraulically or pneumatically lockable gas spring 8 is provided, the cylindrical housing of which is located in the upper region of the guide tube 1 and protrudes upwards from it, while its piston rod 10 protrudes downwards from the housing 9 and with the Base plate 5 is detachably connected.
  • the free end of the piston rod 10 is formed with a reduced-diameter pin 11, on which an axial ball bearing 12 is arranged, the upper race 13 of which is supported against the collar 14 formed at the transition between the pin 11 and the piston rod 10, while the lower race 15 is supported against the base plate 5.
  • a locking ring 16 is attached to the pin, which holds the thrust ball bearing 12 in the position shown, even if the lower race 15 is not supported against the base plate 5.
  • the pin 11 passes through the opening 7 with a sufficient radial play of a few tenths to a millimeter, so that the piston rod 10 is not radially clamped relative to the guide tube 1.
  • a washer 17 is pushed onto the pin 11, the diameter of which is larger than the diameter of the opening 7.
  • a securing element 18 is pushed, so that the piston rod 10 of the gas spring 8 is axially fixed but releasable with the guide tube 1 is connected.
  • the continuous circular cylindrical housing 9 of the gas spring 8 is arranged in a tube 20 with a sliding fit, which is also circular cylindrical over its essential length, ie the radial play between the housing 9 and the tube 20 is a few hundredths to a maximum of 1 or 2 tenths of a millimeter.
  • the game is just such that the housing 9 of the gas spring 8 can be inserted into or pulled out of the tube 20, but at the same time the housing 9 is radially guided and held in the tube 20.
  • This tube 20 which forms a detachable part of the gas spring 8, is provided in its upper region, projecting beyond the housing 9, with a conically tapering fastening section 21, which is used to produce a fixed plug connection which is easy to manufacture an appropriately designed hub 22 is used, which is attached to the underside of a chair, armchair, table top or the like.
  • a sleeve 23 is arranged in the tube 20 in accordance with the tapering of the tube 20, which sleeve is thus axially fixed in the direction of the fastening section 21.
  • the housing 9 of the gas spring 8 is supported axially firmly against this sleeve 23.
  • the housing 9 is held axially in the tube 20 by means of a releasable fastening element 24.
  • This can be a so-called claw, i.e. a ring provided with resilient projections, which can be relatively easily pushed into the tube 20 in one direction, that is to say, against the housing 9, but opposes an opposite movement in that he grips the pipe like a barb.
  • a sufficient effort for example by means of a screwdriver, it can be easily removed downwards, whereby the connection between the housing 9 and the tube 20 is broken in a simple manner.
  • fasteners including screw connections, can also be used.
  • This tube 20, which forms a detachable part of the gas spring 8, is mounted in the usual manner axially displaceably in the guide tube 1, for which purpose this is provided in its upper region with a guide bush 25 made of a suitable plastic.
  • the guide tube 1 and the tube 20 are made of steel.
  • the sleeve 23 consists of a softer material, for example die-cast zinc.
  • Length adjustments of the gas spring 8 and thus height adjustments of the entire lifting device are carried out by actuating an actuating plunger 26 of the gas spring 8 which protrudes from the upper end facing away from the piston rod 10 and which is pressed into the housing 9 to enable the corresponding length adjustments.
  • an upward protruding from the latter protruding body 27 is arranged in the conically tapered fastening section 21, which abuts against the actuating plunger 26 with a contact surface 28.
  • This sliding body 27 is further provided with retaining fingers 29 which engage resiliently behind a corresponding ring 30 on the sleeve 23, as a result of which the sliding body 27 is secured against the actuating plunger 26 against inadvertent falling out or pulling out of the fastening section 21 while at the same time the play surface 28 is largely free from play is.
  • the actuation is carried out by means of a pivotable actuation lever, not shown, which is mounted in the hub 22 in the usual manner and which comes to bear against the outer surface 31 of the sliding body 27, as is known for example from DE-U-70 19 918 (corresponding to US-A-3 790 119) is known.
  • an annular collar 32 is formed on the piston rod outlet end of the gas spring, preferably on the guide and sealing plug usually present there, over which the fastening element 24, which is designed as an elastic clamping ring, is pushed. Subsequently, this collar 32 is flanged to the outside, so that this fastening element 24 is connected to the gas spring 8 so that it cannot move.
  • the assembly of the gas spring 8 in the tube 20 is facilitated to the extent that after inserting the gas spring 8 into the tube 20 only with a soft hammer, such as a rubber hammer or the like. must be struck on the pin 11 of the piston rod 10 in order to fully drive the cylindrical housing 9 of the gas spring 8 into the tube 20 and to bring the fastening element 24 into the locking position shown in the drawing.
  • the fastening element 24 can also be open on one side and pushed transversely under the collar 32. Such a configuration would make it easier to replace the fastening element 24 after the gas spring 8 has been removed from the tube 20.
  • the tube 20 can also have a non-circular cross-section, in particular thus be of polygonal design. In such a case, it should have at least a triangular cross section, expedient configurations having a hexagonal or octagonal cross section. In such a case, the guide bushing 25 should have a correspondingly adapted cross section. If in this way the tube 20 together with the gas spring 8 were made non-rotatable relative to the guide tube 1, the axial ball bearing 12 could of course also be omitted.
  • FIGS. 3 and 4 A further embodiment is shown in FIGS. 3 and 4, FIG. 3 showing some details of the gas spring 8 used.
  • This is constructed in the same way as in the embodiments according to FIGS. 1 and 2 in principle as it is shown and described in DE-C-1812 282 (corresponding to US Pat. No. 3,656,593).
  • a sealing and guide bushing 33 At its piston rod outlet end 10, it has a sealing and guide bushing 33, which can be made in one piece or - as in the present case - in two parts.
  • a multi-lip seal 34 abutting against the piston rod 10 is arranged, which abuts against the piston rod 10.
  • a sealing ring 35 is arranged in it, which bears against the cylindrical housing 9 of the gas spring 8, so that a gas-tight closure is provided here.
  • the cylindrical housing 9 of the gas spring 8 has an edge 36 flanged over this sleeve 33.
  • the sleeve 33 has a sleeve-like section 37 which projects outward from the housing 9 and surrounds the piston rod 10.
  • This sleeve-like section 37 in turn has an undercut 38 adjacent to the edge 36.
  • a so-called claw is arranged as a fastening element 24, which is formed from a ring 39 with resilient projections 40 projecting outwards.
  • This fastener 24 is made of spring steel.
  • the projections 40 are inclined outwards against the direction of insertion 41, so that they can cling to the inside wall of the tube 20 like barbs against the direction of insertion 41.
  • the ring 39 is held axially on the sleeve-like section 37 by means of a locking ring designed as a toothed ring 42, the radially inwardly projecting resilient teeth 43 are held and secured in the undercut 38.
  • the fastening element 24 can thus be mounted and held axially by simply sliding it on and then sliding the toothed ring 42 onto the sleeve-like section 37.
  • the sleeve-like section has - as can be seen in FIG. 3 - two diametrically opposed, mutually parallel flat surfaces 44 which extend to the edge 36 and whose distance corresponds to a standard distance for an open-end wrench.
  • the ring 39 of the fastening element 24 is provided with two associated contact surfaces 45, so that the fastening element 24 is attached in a rotationally fixed manner on the sleeve-like section 37.
  • the sealing and guide bushing 33 with the section 37 is of course fixed in the gas spring 8 in a rotationally fixed manner.
  • a groove 47 (that is, a thread-like incision) is provided which extends several times with a slope.
  • the gas spring 8 By turning the gas spring 8 relative to the tube 20 by means of a wrench which engages the surfaces 44 of the sleeve-like section 37 directly outside the tube 20, the gas spring 8 can be screwed out of the tube 20 due to the engagement of the resilient projections 40 in the groove 47 will.
