Definitions

  • the invention relates to a telescopic table frame for supporting a tabletop of a table at a working height, which is designed for fastening table legs, in particular for height-adjustable table legs of an office table.
  • Known table frames consist of several metal profiles welded together to form a preferably closed profile frame, which forms a table plane that extends essentially horizontally in the installed position, on which a table top is attached on top and to which table feet that extend vertically in the installed position and thus transversely to the table plane are also attached are, which support the table against the floor, so extend between the table frame and the floor.
  • the table legs can be designed either as a T or as an L design in order to implement different installation situations and to improve the tipping stability with larger table loads.
  • the tabletops of office tables usually have a width or depth between 1000-1200mm and different lengths, preferably 2000-2500mm. Since the table frames are usually opposite the table top step back, the outer dimensions of the table frames are correspondingly smaller.
  • the table legs are preferably designed as height-adjustable lifting columns with 2-3 telescopic elements that can be slid into one another like a telescope.
  • the height is normally adjusted by an electric motor with a worm gear, which engages in a spindle built into the lifting columns via a claw coupling.
  • Such a table or the table frame must have a defined lateral and longitudinal rigidity for the table, which is specified in EN 527-2 and -3, in the specifications of the office standards committee in DIN technical report no. 147 and in other internationally valid standards are. This specifies a test procedure for work tables and office cabinets to determine the strength and durability of moving parts.
  • the telescopic elements of the height-adjustable lifting columns are connected to one another by traverses, which are located in the space below the table top, for example at knee height, and restrict the user's legroom.
  • a disadvantage is the high storage costs for different table variants and sizes, because these usually have to be prefabricated and welded and insofar as a relatively large amount of storage space is required for different-sized table frames for different-sized table tops.
  • the object of the invention is to at least partially avoid these disadvantages and to provide a table frame which at least partially avoids the disadvantages mentioned above and in particular reduces the storage costs for different sizes and variants.
  • the telescopic table frame according to the invention is designed to be telescopically displaceable, comprising correspondingly or complementarily designed profiles, comprising at least one first receiving profile for the longitudinally displaceable receiving of at least one further insert profile.
  • the invention is not limited to a profile with only two relatively movable profiles, so three or more profiles can definitely be used.
  • the table frame is designed for longitudinal adjustment, i.e. it includes longitudinally adjustable longitudinal profiles, which are preferably offset to one another are adjustable, so does not include parting planes extending along a common plane.
  • the table frame also includes one or more cross members extending perpendicularly to the longitudinal members, generally parallel to the edges of the table top.
  • the crossbeams are preferably designed to be longitudinally adjustable, although this is usually not the case for reasons of stability.
  • the cross beams can be located as head profiles at the ends of the longitudinal beams. These cross members can be, for example, simple angle or rectangular profiles.
  • crossbeams can also be designed and/or mounted asymmetrically if, for example, the lifting columns are not aligned with the central longitudinal axis of the table top.
  • the telescopic table frame according to the invention comprises two longitudinally adjustable longitudinal profiles which, for example, can form a rectangular frame with the crossbeams or head profiles.
  • two longitudinally adjustable longitudinal profiles which, for example, can form a rectangular frame with the crossbeams or head profiles.
  • This modular construction of the telescopic table frame according to the invention from individual components enables both the realization of a large number of different telescopic table frames and the compact packaging of the individual parts before assembly.
  • the profiles of the table frame is designed as a closed square profile, particularly preferably with a diameter of 40 x 40 mm of the receiving profile body, in which insert profiles with a size of 35 x 35 mm can be used in a longitudinally displaceable manner.
  • a wall thickness of 2mm using metal profiles has proven to be particularly useful.
  • the particular advantage of this preferred embodiment is that the table frame in the collapsed state, i.e. in the fully inserted or compressed state, has a size to be transported on a standard Euro pallet with a length of 120 cm and only during assembly to the Table frame is extended to the required length to carry the table top.
  • the attachment means for attaching the table frame to the underside of the table top are preferably designed so that they realize not only this attachment, but at the same time also fix the table frame in the desired position. This is preferably done using screws that can be introduced into openings in the table frame, ie openings that are aligned in certain positions in such a way that the fastening screws or fastening means can be pushed through.
  • the table frame is preferably designed for the fastening means or screws to be pushed through, in particular through the profiles into the underside of the tabletop.
  • the individual parts of the table frame are preferably made of metal profiles, in particular with a material thickness of 1.5 to 2 mm.
  • the table frame is self-supporting and inherently rigid frame, which defines a bearing surface for the table top, preferably extending horizontally.
  • the longitudinal direction extends along the X-axis
  • the transverse direction along the Y-axis
  • the height adjustment is along the Z-axis.
  • the present embodiment includes a telescopic table frame 2, which is length-adjustable in the longitudinal axis of the table.
  • the telescopic table frame 2 carries a short table top 4, shown in dashed lines, with a length of approximately 1.2 m.
  • a short table top 4 shown in dashed lines, with a length of approximately 1.2 m.
  • table feet 6, 8 At the two front ends of the telescopic frame 2 are height-adjustable, i.e. also telescopically extendable table feet 6, 8, which are continuously adjustable from a lowered position at a working height of about 60cm above the floor to a raised position at a working height of about 1.2m , which preferably takes place via electric motors which are arranged in the columns of the table bases 6, 8 and each drive a spindle accommodated in the table bases via a claw coupling.
  • the telescopic table frame 2 is shown in the maximum collapsed position for a relatively short table top 4 with a length of about 1.2 m.
  • the same telescopic frame 2 is in an extended position for a relative to the embodiment according to FIG figure 1 shown significantly longer tabletop 12 of about 2 m in length.
  • the telescopic frame 2 comprises two telescopically extendable longitudinal profiles 14, 16, which are spaced apart from each other by a distance of about 50 cm and which are connected to one another at the front ends via longitudinal profiles extending transversely to the longitudinal axis (crossbeams) 18, 20 to form a closed frame the tops of the profiles 14, 16, 18, 20 define a support surface for the tabletop 4.
  • the head profiles 18, 20 initially loose and are brought up to the assembly of the telescopic table frame 2.
  • the telescopic table frame 2 is screwed to the tabletop 4, 12.
  • the head profiles 18, 20 are then brought up to the telescopic table frame 2 and also screwed to the table top 4, 12.
  • the telescopic table frame 2 is additionally clamped to the table top so that the table has even more stability.
  • mounting plates 22, 24 are arranged with four through-holes for fastening bolts for the table legs 6.8. These mounting plates 22, 24 are preferably welded between the longitudinal profiles 14, 16 and on the head profiles 18, 20.
  • lifting columns can also be used in which the electric motor is housed in a motor box attached to the upper end of the lifting column and then acts from there, for example via a claw coupling, on a spindle in the lifting column, causing it to be adjusted.
  • the motor housing can be attached to the mounting plate or directly to the longitudinal profiles 14, 16.
  • the synchronous control of the electric motors for adjusting the table height takes place via a circuit box 10 arranged in the middle between the spaced longitudinal profiles 14, 16 for accommodating a circuit, which is connected via cables to the two electric motors in the table legs 6, 8 and a switch, not shown.
  • the telescopic table frame 2 is compared to that in FIG figure 1 shown in the fully collapsed position figure 2 shown in the more extended position, in which the longitudinal profiles 14, 16 are spaced apart and the slide-in profiles 26, 28 accommodated in these connect the longitudinal profiles 14, 16 with one another, the separation of the longitudinal profiles 14, 16 taking place in different planes.
  • the telescopic table frame 2 is optimized for the long tabletop 12 with a length of approximately 2 meters.
  • FIG 3 shows a further embodiment of a table frame according to the invention in its individual parts.
  • the longitudinal profiles 14, 16 are connected at the right end to the mounting plate 24, for example welded.
  • the mounting plate 24 is not flush with the tops of the rails 14,16 but is offset downwardly and outwardly, ie overhanging the ends of the rails 14,16, by small amounts.
  • the head profile 20 is an angle profile in which the vertical leg becomes wider towards the middle. It has a clamping slot 30 near and parallel to its edge.
  • the table frame is designed identically or as a mirror image at its other end, but this does not need to be discussed in more detail for the sake of simplicity.
  • figure 4 shows a similar embodiment in the assembled state, with the protruding edge of the mounting plate 24 is inserted into the clamping slot 30.
  • screws are passed through the four fastening holes on the lifting column and in the mounting plate 24 and screwed into the table top. These screws now pull the mounting plate towards the table top.
  • the head profile 20 is also clamped between the mounting plate 24 and the table top.
  • figure 5 shows the same embodiment in a modified assembly. Here the mounting plate 24 is shifted to the end of the clamping slot 30 . If the head profile 20 is now attached symmetrically to the underside of the table top, the lifting column is no longer directed towards the central longitudinal axis of the table top.
  • Such an embodiment generally also requires a correspondingly asymmetrical design of the table base at the lower end of the lifting column.
