Definitions

  • the invention relates to a support frame for height-adjustable tables, in particular for CAD systems, in which the upper part carrying the table top can be raised or lowered with respect to the lower part resting on the floor by means of telescopic adjustment elements, with additional guides for the upper part and lower part Upper part are provided.
  • a cover plate is attached to the upper part, which is guided laterally in the direction of adjustment of the two parts on the lower part.
  • a box-like part is attached to the underside of the upper part, which is vertically displaceable in a second box attached to the lower part, a telescopic adjusting member being provided within the box-like part of the upper part.
  • the table top is divided, only a narrow strip being adjusted parallel to the floor by the box-like part.
  • the remaining part of the table top is pivotally connected to this narrow strip and rests in its area facing away from the narrow strip on the upper part of the supporting frame, so that when the narrow strip is raised, the table top is inclined, the degree of inclination depending on the extent of the lifting.
  • the box-like guide therefore needs almost no absorption of tilting forces, such a box-like guide being suitable for absorbing tilting forces only to a limited extent, since it tends to jam or pike in particular when the inner box is extended.
  • the invention has for its object to provide a training of the type mentioned, by means of which support frames for tables in particular with free cantilevered table tops can be achieved, which are able to carry high loads.
  • this object is achieved in that, as additional guides on the underside of the upper part, spaced from this, a cross member is attached via rigidly attached, rigid suspensions, the lateral ends of which are guided along guides on the lower part in the adjustment direction of the two parts.
  • an additional table level when arranged above the actual table top, the latter can be supported on the cross member via one or more beams that protrude above the upper part.
  • transverse forces exerted on the additional table level are introduced essentially directly into the lower part of the supporting frame via the cross member.
  • the upper part supporting the table top can be raised or lowered by means of telescopic adjustment members relative to the lower part resting on the floor, and in which the cable routing to and from electrical or electronic devices below
  • the cable duct can be separated by parallel, mutually displaceable plates that run parallel to the adjusting device and in the longitudinal direction of the table, one of which is connected to the lower part and the other to the upper part.
  • the further cable duct can be arranged in the plane of the lifting mechanism for the upper part arranged outside the cable duct located under the table top, a deflection device, for example a deflection plate, being provided at its lower end for guiding the cables into the cable duct located below the table top.
  • a deflection device for example a deflection plate
  • a recess can be provided in the two plates in the upper area, which recesses lie one above the other in the lowered state of the table, the recesses towards the lifting device being covered by an extension of the deflection device extending in the direction of adjustment.
  • the width of the extension measured in the adjustment direction can correspond approximately to the height adjustment path of the additional table level.
  • the cable duct arranged below the table top can be closed to the outside by two removable cover panels that can be displaced parallel to one another in the adjustment direction. This is easy access to the cables is always given, the adjustment movement of the two parts of the support frame is not hindered and the cables cannot be damaged by the fact that they can somehow get into a gap and then be squeezed there.
  • the cable duct arranged below the table top can be closed on its underside by a profile rail, preferably a U-profile rail, which connects the plate arranged on the lower part and the cover panel arranged on the lower part.
  • This profile rail on the one hand achieves a termination of the cable duct, thereby preventing cables from hanging out of the cable duct at the bottom and being damaged there, and on the other hand stiffening the cable duct, since the profile rail bends the plate or cover plate arranged on the lower part prevented.
  • Fig. 1 shows a table provided with the support frame according to the invention.
  • Fig. 2 is a front view of the table of FIG. 1 with the front cover of the cable duct removed.
  • FIG. 3 is an illustration analogous to FIG. 2, but with complete removal of the covers on the supporting frame.
  • Fig. 4 is a section along line IV-IV of Fig. 2nd
  • FIG. 5 illustrates a section along line V-V of FIG. 2.
  • Fig. 6 graphically shows a section, etc. that area in the transition between the upper cable duct and the cable duct located below the table top.
  • a support frame for a table which consists of a lower part 2 and an upper part 3 height-adjustable relative to this lower part by means of a lifting device 14.
  • a table top 4 is attached to the upper part 3, etc. via horizontally projecting table top supports 5.
  • Foot supports 6 are provided on the lower part 2 for support in the same direction as the table top supports.
  • the carriers 8 can be telescopically extended or shortened to achieve the height adjustability.
  • Both the lifting device 14 and the lifting device provided in the supports 8 are conventional lifting devices and can be used, for example, with screw spindles, pressure-resistant cables and the like. be educated.
  • a cable duct is provided below the table top 4 and is covered at the front by means of a cable duct cover 9.
  • the cable duct cover 9 consists of two plates 9 ', 9 ⁇ , of which one, 9', on the lower part 2 and the other, 9 ⁇ , is attached to the upper part 3.
  • the two cover plates run parallel to each other in the direction of adjustment of the two parts and slide against each other.
  • an upper cable duct 10 is provided, which is closed to the front by means of a removable cable duct cover 10 'and to the rear by means of a rigid cable duct cover 10'.
  • the upper cable duct 10 is open from above via an elongated hole 13 in the additional table level 7.
  • the elongated hole 13 runs in the direction of the viewer, so that the screen can be adjusted in the direction of the viewer and away from it.
  • a cross member 15 is rigidly attached via suspensions 16, which is additionally guided via lateral guides 17 on the lower part 2.
  • the cable duct located below the table top 4 is delimited to the lifting device 14 or to the cross member 15 and its lateral guides 17 by means of parallel slidable plates 19 'and 19', which form the rear cable duct boundary 19.
  • one, 19 ' is on the lower part 2 and the second, 19 ⁇ , attached to the upper part 3, so that when the upper part is adjusted in height with respect to the lower part, the two plates move towards one another analogously to the cable duct cover 9.
  • a rear cover 20 is provided, which is formed in an analogous manner by parallel plates 20 ', 20', which are mutually parallel in the stroke direction, of which again a plate, 20 ', on the lower part and the another plate, 20 ⁇ , is attached to the upper part. It is thus covered both the lifting device and the cable duct so that a reliable conclusion is always given by the sliding plates.
  • the cable duct cover 9 is removable to make the cable duct located below the table top 4 accessible.
  • sockets 21 are provided for cables 22, the cable duct located below the table top 4 being connected to a horizontally running cable duct 28, with which the cables laterally to adjacent tables and the like. can be performed.
  • a lateral cable passage 11 is provided in the cable duct located below the table top 4 and a lateral cable passage 12 in the cable duct.
  • the cable duct located below the table top 4 is closed off by a lower cover profile 30, which profile also prevents the cables from sagging downwards.
  • the upper cable duct 10 is in the plane of the guides 17 or the cross member 15 and the suspensions 16, whereas the cable duct located below the table top 4 lies in front of this plane and is separated from the guide by the cover 19 is.
  • a cable deflection 23 is provided at the lower end of the rear cover 10 ⁇ of the upper cable duct 10, which has an extension 24 which runs parallel to the cable duct boundary 19 and on this is led along.
  • a cable duct 29 is provided, through which the cables are deflected forwardly into the cable duct located below the table top 4.
  • the plates 19 'and 19 ⁇ have recesses 26 and 25, respectively, the recess 26 in the lower plate 19' for the guide 17th is covered by the plate 19 ⁇ attached to the upper part 3 and the recess 25 in the plate 19 ⁇ is closed at the rear by an extension 24 of the cable deflection 23, thereby preventing the cable from escaping to the guide 17.
  • the provision of the recesses 25, 26 in both plates of the cover 19 is necessary because the height adjustability of the additional table level 7 must also be given when the upper part of the support frame carrying the table top 4 is in the completely lowered position.
  • the recesses 25 and 26 are approximately congruent one above the other.
  • the cable passage 29 is then at the lower region of the recesses 25 and 26, and when the additional table plane 7 is raised, in the upper region thereof.
  • the horizontal cable duct 28 which is accessible from above by horizontal displacement of the table top 4, is formed in the area of the passage of the upper cable duct 10 by two mutually directed C-profiles, the gap between the two C-profiles both the upper cable duct 10 and the cables 22 are passed through.
  • the two C-profiles are connected to one another at the bottom, as a result of which a closed cable duct is created.
  • the C-profiles are attached with their lateral ends to the upper part 3 of the support frame 1, and thus connect the side parts of the upper part of the support frame.
  • the side parts of the lower part of the support frame are rigidly connected to each other by the plates 19 'and 20' attached to it.
  • the upper part of the support 8, which is connected to the additional table level 7, is guided either in the table top 4 or in the part of the upper part 3 that supports it.
  • the rear boundary that is to say the rear C profile of the horizontal cable duct 28, can also be used for the guidance.
  • the cables 22 guided in the cable duct located below the table top 4 are guided on the one hand via the cable duct 29 into the upper cable duct 10 and from there through the slot 13 to the additional upper table level and on the other hand through a cable duct 27 provided in the table top to the top the table top, on which the operating devices of the EDP or CAD system, ie a keyboard, a tray or the like, is then located.
  • the support frame With the design of the support frame according to the invention, it is thus possible to achieve high adjustment ranges of the table top 4.
  • CAD systems for example, it is necessary for the operator to operate the operating devices both while sitting and standing.
  • adjustment ranges of the order of 40 cm occur.
  • an additional adjustability of the additional table level 7 is to be achieved in order to be able to easily adapt the workplace to the individual needs of the person operating it.
  • the height adjustment is carried out via conventional organs, which u. Like. are operated. Since this height adjustment is conventional, the lifting devices have not been shown in detail.
