Definitions

  • the invention relates to a table, in particular a writing or office machine table with a cable duct which extends substantially below the surface of the table top along the rear edge thereof.
  • the cable duct below the surface of the table top. In this position, it is usually provided with an upper cover, which has suitable outlet openings for cables and can be moved, opened or lifted in such a way that the cable duct is accessible from above in order to be able to plug device plugs into sockets fastened to its base. If the table is against a wall and is chained to neighboring tables, you have to bend over the entire table surface to be able to see the bottom of the cable duct and the sockets attached there. In addition, such cable ducts accessible from above very often lead to short circuits when coffee or a flower vase is poured out on the table and the liquid penetrates from above or below into one of the sockets installed on the bottom of the cable duct.
  • the invention is therefore based on the object of creating a table of the type mentioned at the beginning, in which the cable duct is more accessible and at the same time the risk of short circuits is substantially reduced.
  • the table top can be lowered at least with its rear edge in front of the cable duct and this is accessible through a front opening.
  • Tables are known in which the table top can be adjusted in height or pivoted in such a way that the rear edge is lowered relative to its normal position. So far, however, this fact has not been used to access the cable duct from the front.
  • a front opening of the cable duct has the advantage that sockets attached to its rear wall are clearly visible from the front, liquid spilled on the table surface does not penetrate into the front access opening of the cable duct, which is covered at the top, and, if this should happen, not immediately the level of Cable ends and contacts reached in the sockets attached to the rear wall of the cable duct.
  • the cable duct is particularly easily accessible if it is sufficient to swivel the table top to expose its front opening. In individual cases, however, a vertical movement of the table top, possibly combined with an additional slight inclination to the rear, can have the advantage that the objects lying on the table do not need to be cleared away if the cable duct is to be made accessible.
  • the table shown has a table top 10 which is movably mounted and guided on a table frame 12.
  • the table top 10 is divided into a lower part 14 and an upper part 18 which is pivotably mounted thereon via a joint 16 with a horizontal axis.
  • the table frame 12 consists of two legs 20 arranged on the lateral edge edges of the table top 10, the upper ends of which are located behind the table top and the lower ends of which rest on the floor approximately perpendicularly below the front edge of the table top.
  • these In the upper area about 3/4 of the height of the legs 20, these have the shape of an arc, the center of which is located approximately at the front edge of the table top 10.
  • the radius can e.g. 67.3 cm.
  • the legs Towards the lower end, which in the example is slightly set back from the front edge of the table top, the legs extend in a straight line with an essentially tangential connection to the upper circular arc.
  • legs 22 extend obliquely backwards and downwards on the legs 20, which extend to approximately perpendicularly below the rear edge of the table.
  • the upper ends of the legs 20 are connected to one another by a flexurally and torsionally rigid cable duct 24, which forms a traverse.
  • 3 shows a cross section through the cable duct 24.
  • the legs 20 be an extruded profile made of an aluminum alloy and be firmly connected to the upper ends of the legs 20 by means of adapters.
  • the profile is closed at the bottom, rear and essentially also at the top.
  • the upper side is expediently covered with a plate 26, which corresponds to the upper part 19 of the table top 10, so that there is a uniform surface impression from the front edge to the rear edge of the plate 26.
  • the cable duct 24 has an opening which is accessible from the front and which can be closed by a front wall 28 in the form of a pivotable flap hinged at the bottom, a slot in the front of which remains open in the closed state, through which cable can be led out of the cable duct 24.
  • These cables extend upwards through a gap between the cover plate 26 and the table plate 10 onto the table surface.
  • Sockets 30 for device plugs are attached to the inside of the rear wall of the cable duct.
  • the legs 20 curved in a circular arc are firmly connected to a concentrically curved toothed rack 32, which could also be referred to as a segment of a ring gear.
  • 4 has a substantially T-shaped cross section, so that it can be engaged by two angled ends of a gear housing.
  • the two gearboxes one of which is located next to each table leg 20, together form the lower part 14 of the table top 10.
  • the arcuate rack 32 on the back of which the angled, circularly curved ends of the gearbox either slidable directly or with the interposition of a layer
  • the material 34 is in sliding contact, thus constituting an arc-shaped guide for the lower part 14 of the table top 10.
  • the play-free engagement of the driving gearwheels 36 mounted in the gearbox housings in the toothed rack 32 also ensures play-free engagement on the rear side of the rack 32.
  • the driving gearwheels 36 are stored approximately in the middle of the guided arc length of the table top lower part.
  • plastic rollers 38 shown in FIG. 5 can be rotatably mounted on the lower part 14 near its lower ends, which are supported on the radially inner surface of the legs 20 when the table top 10 is subjected to very high loads.
  • a screw 40 mounted in the tabletop lower part 14 is rotated from the front of the table via a crank (not shown) according to FIG. 5.
  • the worm 40 drives a worm wheel 42 and thus a gearwheel which is non-rotatably seated on its shaft and which meshes with an intermediate gear 44 which in turn meshes with the driving gearwheel 36.
  • the shaft of the worm wheel 42 extends between the two gear housings in front of the table legs 20, so that in both gear housings, which together form the table lower part 14, gear wheels 36 driving synchronously are driven via intermediate wheels 44.
  • the worm drive 40, 42 ensures because of its self-locking that the table top 14 in a position set by means of the crank on the curved rack 32 remains locked, regardless of how high the table top is loaded.
  • the tabletop upper part 18 is pivoted by hand about the hinge axis 16 relative to the lower part 14.
  • an arcuate row of holes can be attached to the latter, which come into flight when the upper part 18 is pivoted with a locking bolt mounted thereon.
  • a rod 46 is rotatably mounted at its upper end on the upper part 18, which in a first variant is provided with a series of holes into which a locking bolt 48 mounted on the lower part 14 can be inserted.
  • the rod 46 can be a toothed rack or threaded spindle which is held by a counter-pressure bearing 50 in engagement with a toothed or worm wheel 52 which e.g. is to be fixed or released in a non-rotatable manner by means of a releasable clutch or brake, a spring-loaded detent ball 54 engaging in the gearwheel 52 generating a certain rotational resistance.
  • the table top 10 pivots according to the arrows shown in FIG. 1 with its rear edge upwards or below, while its leading edge remains essentially at the same level.
  • a slope of the table surface falling from back to front of about 8 to 10 ° is sufficient.
  • the front opening of the cable duct 24 can be exposed, e.g. Insert the device plug into the sockets 30 installed on the rear wall of the cable duct from the front of the table.
  • the back of the table can stand against a wall and can be chained to the side of other tables. After the table top 10 has been pivoted back into a central horizontal position, the cable duct 24 is again essentially inconspicuously below the work surface of the table.
  • the shape of the table legs shown allows a lightweight construction with sufficient load-bearing capacity, which gives the person working on the table a lot of freedom of movement.
  • the table could, however, also have essentially closed side walls with arch-shaped guides attached to their inner sides, the center of which lies near the front edge of the table top.
  • a more or less closed rear wall could be provided, which connects the side walls or legs to one another.
  • Another drive could also be provided for the movement of the lower part 14 along the curved guide 32.
  • a worm engages directly in a worm wheel seated on the shaft of the driving gear wheels 36.
  • a gear can also be provided for pivoting the table top part 18 about the hinge axis 16.
  • the toothed or worm wheel 52 could be driven in rotation, and preferably again by means of a crank from the front of the table.
  • the drive could also be derived from one of the gears of the transmission 36-44, it being possible to ensure by means of a coupling device that only the driving gears 36 and the gear or worm wheels 52, which are also arranged in pairs, are driven via the worm 40.
  • both the gears 36 and the toothed or worm gears 52 are driven simultaneously via the worm 40, the speeds being selected by a suitable choice of the gear ratios such that the pivoting movement of the table top part 18 about its leading edge is compensated for by the simultaneous pivoting about the hinge axis 16, so that essentially only a vertical movement of the table top part takes place.
