  • DE 34 01 303 A1 describes a connector for connecting a first component to a known second component, which has a first connecting plate, which with its rear surface is attachable to the first component, and a second connecting plate, which with its rear surface can be fastened to the second component, the first connecting plate being attached has a projection on its front surface, and the second connecting plate has a projection Recess in which the projection of the first connecting plate engages, the Projection and the associated recess to form a supporting projection / recess unit are determined. There are the projections and recesses along two superimposed, elongated areas, and accordingly prevent. the Components from moving toward the pads and rotating.
  • EP 0 866 186 A2 provides that the second connecting plate has a plate thickness, which corresponds at least to the dimension by which the projection is transverse to the first Connection plate protrudes over this; that each projection has an end region in which it has a larger cross section than in its closer to the first connecting plate Area; that each recess increases with increasing distance from the front surface expanded so that the connecting plates touch with their front surfaces; and that the first connecting plate has at least one further projection on its front surface, to form an at least rotation-prevented projection / recess unit is provided.
  • the present invention has for its object the wooden connector of the beginning described genus (see also preamble of claim 1) esp. Avoiding the to improve the aforementioned disadvantages, including significantly reduce manufacturing costs, and yet the structural strength of the connector arrangement (esp. by clear Reduction of surface pressures with the same stress) to increase significantly, whereby at the same time the required extent of milling work with a concealed arrangement by approx. 50% can be reduced, and in the case of an arrangement with a shadow gap, its width is increased / decreased by approx. 50% should be reduced.
  • this object is achieved in that the (at least one) Projection of the first connecting flange integral with the first connecting flange is formed, and from the lower edge of the first connecting flange in the Plane extends or is aligned with the plate plane, the latter technically or geometrically is more appropriate since a plate-shaped structure is three-dimensional, and - strictly speaking - does not form a "level".
  • the plate thickness of both connecting flanges is generally generally i.w. same size and is approx. 6 mm - 12 mm.
  • first connecting flange formed (locking) projection of the first connecting flange i.w. centered on the lower edge of the first connecting flange arranged, and i.a. preferably mirror-symmetrical to the longitudinal center line of the first Connection flange / the wooden connector formed.

  • Unlocking the two connecting flanges can cause the slot-shaped Recessing "legs" of the second connecting flange with a Force component are applied to the outside, it is preferably provided that the Projection of the first connecting flange facing, extending on both sides of the projection End face sections of the first connecting flange, which in the assembled state with the end face sections on both sides of the slot-shaped recess of the second Connection flange
  • the contact surfaces of the two connecting flanges at an angle incline inside the two become the slit-shaped recess of the second connecting flange enclosing "legs" by the vertical force component of the embossed Force pressed inward, and the more the greater this force component is. It unlocking can therefore no longer occur with the described torsion. Rather, this beveling of the end face sections leads to further security unlocking because the two connecting flanges have a tendency to contract.
  • the helix angle is chosen so that the bending stiffness of the "Legs" of the second connecting flange (with permissible load capacity) the horizontal Force component can overcome.
  • the through bores of both fastening flanges are preferably countersunk bores with enlarged recesses for receiving the heads of the rod-shaped connecting means trained because their heads to be connected to each other during the assembly process Components do not have the parallel to the respective connection surface of a connecting flange May stand out area in order to be able to carry out a simple, flawless assembly.
  • connection flanges There are preferably at least some through holes in the connecting flanges formed so that they are at an angle to the respective pad (and thus also to the this parallel surface) to achieve that the connecting means with reduced Shear force (and therefore on tension) are loaded because of rod-shaped connecting means Train are much more resilient than with shear and bending forces Overhung load.
  • the helix angle of the side surfaces of the slot-shaped recess is generally prefers between about 30 ° and 60 °.
