Definitions

  • the invention relates to a work or office table with a table frame and a worktop, in which the table frame has a horizontal crossbar with table legs, on the long sides of which a pair of support arms are directed towards the front and rear of the worktop and can be pivoted in pairs in vertical planes , in which the free ends of the support arms are articulated on holding elements and are adjustable perpendicular to the crossbar.
  • a work or office table of this type is known from EP-A-0 364 822 and from unpublished DE-A-40 28 452. With such a table frame, the height and the inclination of the worktop can be changed and the set height and inclination of the worktop can be locked.
  • guide rails with adjustable sliders or slides are required on the underside of the worktop, on which the free ends of the support arms are articulated.
  • additional devices are required to keep the worktop in its assignment to the free ends of the support arms. Overall, this requires a considerable amount of parts on the underside of the worktop.
  • the free ends of the support arms can each be pivoted to a limited extent with a holding element designed as a mounting plate about a horizontal articulation axis running parallel to the cross-beam, in that the mounting plates are directed in pairs towards one another, the articulation axes pointing away from one another Ends of the mounting plates are arranged, that the mounting plates are each provided with an oblong hole directed perpendicular to the cross-member, that in the elongated holes in each case a clamping screw fixedly arranged on the underside of the worktop at predetermined intervals can be adjusted and locked, and that the mutually facing ends of the elongated holes and the opposite ends of the elongated holes in the fastening plates in connection with the clamping screws arranged on the worktop fix the end pivot positions of the support arms.
  • the associated pair of support arms can be pivoted up or down by pulling on the front or rear edge of the worktop or by pressing on the worktop, the height and inclination of the worktop changing. If the worktop has the desired height and inclination, the clamping screws are tightened and the set worktop is locked in place.
  • the fixed arrangement of the clamping screws on the underside of the worktop is achieved in a simple manner by inserting threaded bushes into the underside of the worktop, into which clamping screws provided with a knurled disc are screwed.
  • the design is such that the clamping screws assigned to the front pair of support arms are arranged at a distance from the front edge of the worktop which corresponds to the distance of the clamping screws assigned to the rear pair of support arms from the rear edge of the worktop, and that the distance to the Bottom of the worktop attached clamping screws perpendicular to the crossbar corresponds to the distance between the articulation axes of the mounting plates at the free ends of the support arms set approximately to the middle of the swivel range. In this way, the worktop is supported and carried approximately symmetrically regardless of the setting of the support arms.
  • the pivot mounting of the mounting plates at the free ends of the support arms is carried out in such a way that the free ends of the support arms carry at least two mounting brackets, between which a bearing eye of the mounting plate is pivotally mounted by means of the articulation axis.
  • the articulation can also be carried out in such a way that the fastening plates have two bearing eyes, between which bearing brackets of the support arm halves are arranged and are pivotably mounted on the articulation axis.
  • the limitation of the pivoting movement of the mounting plates at the free ends of the support arms is achieved in a simple manner in that the free ends of the mounting arms have a limit stop which projects into a recess in the bearing eye of the mounting plate which limits the pivoting movement of the mounting plate. Due to the size of the recess, the pivoting range of the mounting plate can be adapted to the pivoting range of the support arms.
  • the pivot bearing of the support arms on the crossbar is designed according to one embodiment so that convexly curved, arc-shaped dovetail or T-bars are attached to the articulation points of the support arms on the crossbar and that each support arm is composed of two shell-shaped support arm halves, which on the Crossbar facing ends form a concave, circular arc-shaped receiving groove for the dovetail or T-bar and enclose it so that the support arm is held captive on the dovetail or T-bar and can be pivoted to a limited extent.
  • an embodiment provides that the long sides of the crossbar are designed as hollow profiles into which inserts are inserted, and that the dovetail or T-webs are screwed through the hollow profiles Insert pieces are screwed.
  • FIG. 1 shows the cross section of the crossbar 10 of a table frame.
  • the crossbar 10 is substantially U-shaped, the side legs being designed as hollow profiles 12 and 13.
  • Connection bracket 11 stiffen the crossbar 10 at the points where table legs 19 are attached.
  • the U-shaped cross-member 10 forms a cable duct which can be closed by means of a cover 18.
  • the support arms 20 are attached to convexly curved, arc-shaped dovetail or T-webs 16, which, as the view according to FIG. 2 shows, are connected to the crossbar 10 by means of screws 33.
  • insert pieces 14 of corresponding cross-section are inserted into the hollow profiles 12 and 13, into which the screws 33 are screwed through the hollow profiles 12 and 13.
  • the support arms 20 are composed of two shell-shaped support arm halves 29 and 29 'with their open sides facing each other and held together with screw connections 21.
  • the support arm halves 29 and 29 ' form at the ends facing the crossbar 10 a concavely curved, arcuate receiving groove for the dovetail or T-bar 16 and enclose it so that the support arm 20 is held captive on the dovetail or T-bar 16 and can be pivoted to a limited extent, as can be seen from the positions of the right supporting arm designated by 20 ′ and 20 ′′ in FIG. 1.
  • the support arm halves 29 and 29 'of a support arm 20 carry molded mounting brackets 22 and 22' at the free ends.
  • the bearing brackets 22 and 22 ' receive a pivot axis 23 and 23' with which a bearing eye 27 and two bearing eyes 27 'of a mounting plate 26 and 26' are articulated with the support arm 20 can be connected.
  • the bearing tabs 22 can enclose the bearing eye 27, as can be seen in FIG. 2, or the two bearing eyes 27 'can include a bearing tab 22' composed of two support arm halves 29 and 29 ', as shown in FIG. 3.
  • This articulation with the articulation axis 23 or 23 ' is designed such that the mounting plate 26 or 26' can be pivoted to a limited extent.
  • the limitation of the pivoting movement of the mounting plate 26 or 26 ' can be achieved by a limit stop 24 which projects into a recess 25 in the bearing eye 27.
  • the recess 25 limits the pivoting movement of the limit stop 24, which is adapted to the pivoting range of the support arms 20.
  • the articulation of the mounting plates 26 and 26 ' takes place in such a way that the front mounting plates 26 and the rear mounting plates 26' are directed towards one another and perpendicular to the crossbar 10.
  • the mounting plates 26 and 26 ' are each provided with an elongated hole 28 and 28'. These slots 28 and 28 'are also aligned perpendicular to the crossbar 10.
  • Clamping screws 32 and 32 ′ are attached to the underside of the worktop 30 in a predetermined assignment, which can preferably be screwed into threaded bushings 31 which are embedded in the underside of the worktop 30.
  • the clamping screws 32 and 32 ' are adjustably guided in the elongated holes 28 and 28' of the associated fastening plates 26 and 26 'and, when tightened, can position the fastening plates 26 and 26' on the worktop 30 lock.
  • the associated articulation axis and the clamping screw are marked with 23 'and 32'.
  • the opposite ends of the elongated holes 28 and 28 'of the front and rear mounting plates 26 and 26' define the uppermost position of the worktop, as shown with the position 20 "of the support arms and the position 30" of the worktop in FIG. 1.
  • the associated positions of the articulation axis and the clamping screw are designated 23 "and 32".
  • the clamping screws 32 are fixed at a distance from the front edge of the worktop 30 which corresponds to the distance of the clamping screws 32 ′ from the rear edge of the worktop 30.
  • the distance of the clamping screws 32 from the clamping screws 32 'perpendicular to the crossbar 10 is selected so that the clamping screws 32 and 32' approximately in the middle of the pivot position of the support arms 20 and 20 'in the middle of the elongated holes 28 and 28' of the associated mounting plates 26th and 26 'stand.
  • the associated support arm pair can be pivoted upwards by pulling on the facing edge of the worktop 30, while the associated pair of support arms is pivoted downward when pressure is applied to the facing edge of the worktop 30.
  • the pairs of support arms are preferably successively in the desired position pivoted to adjust the height and inclination of the worktop 30.
  • the slots 28 and 28 'of the mounting plates 26 and 26', the pivoting movement of the mounting plates 26 and 26 'on the support arms 20 and 20' and the pivoting movement of the support arms 20 and 20 'on the dovetail or T-webs 16 of the crossbar 10 are matched to each other and to the desired height and inclination adjustment of the worktop 30.
