Definitions

  • the invention relates to a base frame for tables, benches or the like. With at least two base parts arranged approximately vertically at a distance from one another with projecting support arms, the base parts being connected to one another via an approximately horizontally extending profile piece and being rotatable relative to one another about the longitudinal axis of this profile piece and can be locked in the appropriate positions.
  • An adjustable support device in particular for furniture with four feet, has already become known, one of the pairs of feet being arranged so as to be lockable relative to the other under the action of a friction force that can be canceled.
  • a lateral stop is provided on one of the pairs of feet, against which two movable, self-locking wedges under pressure are effective.
  • Such an adjustable support device is quite complicated in construction and therefore also expensive.
  • it is disadvantageous that the one pair of swiveling feet cannot be connected directly to the table top.
  • Such an adjustable support device can therefore easily be released, so that in turn a not exactly stable table, bench or the like. is created.
  • the invention has therefore set itself the task of creating a structurally simple base frame for tables, benches or the like, which can be easily adapted to uneven floors.
  • the profile piece is connected to one foot part in a torsion-resistant manner and in the area of its other end carries an arm which projects approximately at right angles, which arm can be pivoted relative to the other foot part and can be locked on this foot part, and that the foot parts with the table or Bench plates or slats are firmly connected.
  • This configuration according to the invention provides a very simple possibility of rotating the two foot parts relative to one another.
  • the position that is set in each case is particularly stable since the table or bench tops or slats counteract the adjustment movement, especially since these sheets or slats are twisted about their longitudinal axis during adjustment.
  • FIG. 1 shows an oblique view of a table with a base frame; an oblique view of a table with a base; Fig. 2 is an enlarged view of the connection of the one foot part with the horizontally extending profile piece connecting the two foot parts, with sections of the foot part being cut open for clarity.
  • a table which consists of a base frame 1 and slats 2 arranged on this base frame. Instead of the slats 2, it is of course also possible to provide a plate which extends over the entire surface. The same arrangement is of course also possible for benches and other objects with bases, i.e. wherever an adjustment to compensate for uneven floors is desired.
  • Two base parts 3 and 4 which are arranged at a distance from one another and run approximately vertically and are provided with cantilevered support arms 5, are provided as the base frame.
  • Variously designed feet 6 can be provided on these support arms.
  • the foot parts 3, 4 are connected to one another via an approximately horizontally extending profile piece 7.
  • the two foot parts are around the longitudinal axis of the profile piece 7 rotatable relative to each other and lockable in the corresponding positions.
  • the profile piece 7 is firmly connected to the one foot part 3, this connection being made, for example, by welding or by means of a cross bolt.
  • an arm 9 projecting approximately at right angles is provided, which arm is connected to the profile piece 7 in a rotationally fixed manner.
  • the profile piece 7 is expediently designed as a one-piece tube, it having a circular cross section in the exemplary embodiment shown. Of course, other cross-sectional shapes are also conceivable for this profile piece, it only having to be rotatable relative to the foot part 4.
  • the arm 9 can be welded directly to the profile piece if the arm 9 lies outside a central support 10 of the foot part 4. In the exemplary embodiment shown, however, this arm 9 lies within the carrier 10 designed as a hollow profile, the arm 9 then expediently being fastened to a sleeve 11 which can be pushed onto the profile piece 7. The sleeve 11 is then held by a bolt 12 on the profile piece 7. In this way, simple assembly can also be carried out within the carrier 10, since the arm 9 can be inserted through this carrier 10 and then placed on this profile piece 7 by inserting the profile piece 7. It is then only necessary to provide an opening in the side of the carrier 10 in order to insert the bolt 12.
  • the arm 9 In order to ensure the best possible setting of the two foot parts 3 and 4 relative to one another, the arm 9 must be infinitely adjustable and fixable relative to the foot part 4.
  • the arm 9 can be adjusted relative to the foot part 4 by means of a screw spindle 13.
  • the screw spindle 13 penetrates the carrier 10 and the free end of the arm 9.
  • the screw spindle 13 is by appropriate means, such as. on the screw spindle 13 fixed nuts 14 secured against axial displacement.
  • a threaded part is embedded, for example in the form of a nut 15, through which the screw spindle 13 is guided.
  • the arm 9 is expediently designed as a rectangular hollow profile, the screw nut 15 being inserted into the free end of the arm 9.
  • the arm is expediently dimensioned such that two parallel surfaces of the outside of the screw nut bear against the narrow side walls, so that the nut 15 is held against rotation.
  • the clear width of the arm 9 is somewhat larger than the height of the screw nut 15, so that it can move somewhat transversely to its axial direction. This is necessary because by pivoting the arm 9 within the carrier 10 this arm 9 assumes different angular positions with respect to the screw spindle 13.
  • correspondingly large through holes 16 are provided, through which the screw spindle 13 is guided.
  • a handle 17 is provided at the other end of the Screw spindle 13, in order to bring about the adjustment movement in a simple manner.
  • this could also be designed with a cambered surface and rest with the highest elevations on the inner wall of the arm 9, so that a pivoting movement transverse to the axial direction of the same is also possible.
  • the arm 9 in different ways and also to provide different fastening options for the threaded part used.
  • the threaded part itself does not necessarily have to be designed as a nut 15.
  • eccentric bolts could of course also be provided for the adjustment, which are either mounted in the carrier 10 and supported on the arm 9 or are supported on the arm 9 and are supported on the carrier 10.
  • the arm 9 could of course also be arranged outside the carrier 10, but this is then visible from the outside and may be exposed to the weather.
  • the expedient embodiment is therefore to mount it within the carrier 10.
  • the arm could also be made correspondingly long, so that an adjustment by hand would possibly be conceivable.
  • the carrier 10 of the foot part 4 and the arm 9 would then have to be moved accordingly in opposite directions. It would then be conceivable to provide different locking points in which a mutual locking of the arm 9 and the carrier 10 is possible.
  • the present invention provides a simple adjustment option for adapting to uneven floors, which is particularly useful for furniture, such as tables or benches, which are always set up outdoors. Without lifting the table top or loosening a special connection, the adjustment movements can be carried out by simply actuating a handle with a screw spindle. In addition, the required parts can be attached protected from the weather within a central support of a foot part.
  • this profile piece 7 can also be provided further up on the foot parts 3 and 4, as well as immediately below the table top or the table slats 2. However, for reasons of stability of the table or the bench, attempts are made to arrange this profile piece 7 as deep as possible. At tables, the deep arrangement is very useful because this profile piece 7 can also serve as a footrest there.
  • the base parts 3 and 4 can be produced in a simple manner as one-piece welded constructions by this configuration, which has a significant advantage over the known configurations.
  • the special strength between the foot parts and the table tops or table slats 2 is always guaranteed.
