Definitions

  • the invention relates to a method for producing a frame connected by means of transverse strips longitudinal strips frame for a slatted frame, according to the preamble of claim 1, and a mounting device for carrying out the method according to the preamble of claim.
  • Slatted frames typically have a frame consisting of longitudinal strips connected to one another by means of transverse strips, on which frame the slats forming the slatted base, extending substantially parallel to the transverse strips, are arranged.
  • the frame for the slatted frame is mainly produced manually or semi-automatically.
  • Prefabricated longitudinal and transverse ledges are made using different gauges assembled to the frame and connected together.
  • the joining of the longitudinal and the transverse strips is typically done by dowels and gluing. Several steps are required for this. First, dowel holes must be drilled in the end faces of the transverse strips and at the corresponding points in the longitudinal sides of the longitudinal strips. Then glue is placed in the dowel holes, one dowel is used at each connection point and the individual parts are pressed together until the glue has set. In addition, it is known to additionally secure the compounds by screws, or to connect the longitudinal and transverse strips by means of screws.
  • screw holes having different diameters in the longitudinal and in the transverse strips must be drilled at the corresponding locations, wherein the screw holes in the longitudinal strips must be countersunk.
  • the laths which have been elaborately prepared with dowels and / or screw holes, must be positioned precisely relative to one another, and be connected to one another under great manual labor.

In addition, the individual steps are associated with a variety of ergonomically unfavorable Bück- and lifting activities.
  • the invention is therefore based on the object to develop a method and a mounting device for the production of frames for slatted frames, which eliminate the disadvantages of the prior art.
  • brackets can be set so that each bracket is connected with its one half with a longitudinal and with its other half with a cross bar and so holds the strips together.
  • screw holes can be drilled through the longitudinal strips through the front side into the transverse strips.
  • the inventive method has over the prior art has the advantage that the cross bars no longer need to be manually held in place by the spring load, which greatly simplifies the production of solid connections between longitudinal and transverse bars.
  • An advantageous embodiment of the invention provides that the two stops are arranged on a base frame in a substantially vertical direction spaced from each other, and the second, upper stop is upwardly displaceable against a spring load and comprises means for holding the second, upper longitudinal bar, so that it does not fall off.
