Definitions

  • the invention relates to a swivel fitting for a seat or Lying furniture according to the preamble of claim 1.
  • Swivel fittings of this type are used in particular for slatted frames used with pivotable head and / or foot parts.
  • a Adjustment of the inclination is within the by the notches predetermined angular positions possible.
  • the pivotable section i.e. for swiveling in the swivel lever it must first be swung open until the control part reaches a section of the locking lever without locking and enables reversing into the pivoting position.
  • DE U 88 05 573.6 is a swivel fitting became known in which both the pivot lever, as well as the support lever, but not the locking lever as in cross section U-shaped profiles are formed.
  • the locking lever can however, be pivoted completely into the pivot lever.
  • EP A 681 800 is a genre comparable Swivel fitting has become known, in which the locking lever as is formed in cross section approximately U-shaped profile, the Notches are formed by material deformation. Such one Swivel fitting enables improved lateral stability also a complete pivoting of the locking lever in the Pivoting lever.
  • the classic rack as in the DE U 88 05 573.6 shown, exists in the material deformation formed detents, however, a certain danger of poor engagement and therefore unintentional swiveling under pressure. Also the torsion stability of the U-legs the locking lever is not yet optimal.
  • the support lever can advantageously at least on the supporting End also have an approximately U-shaped configuration.
  • the additional support on the side U-legs causes a high degree of locking security and resilience. Locking is particularly important in the case of sudden stress guaranteed from any intermediate position.
  • the material deformations can be from the outside of the U-shaped Locking lever directed towards the inside which reduce the clear width on the inside.
  • Other material deformations such as individual material blocks or the like would be conceivable. From manufacturing technology For reasons it is important that the material deformation by cold forming on a suitable press can.
  • the support lever is advantageous as a closed cross-section hollow box-shaped profile. This also makes the Support lever additionally stiffened.
  • the control section is particularly useful between the notches the U-legs of the locking lever in a linear guideway guided.
  • the control part comes from the outside not disturbing in appearance.
  • the control part advantageously has a guide section for the Guide in the locking lever and a control section for the change the support lever between the support positions and the pivoting position on.
  • the control section on a Drag hooks must be attached to the support lever in such a way that the Control part dragged along when swiveling the swivel lever becomes.
  • the control section also has a push surface on which the control part when swiveling the swivel lever is pushed through the support lever.
  • Such a control part can also be easily assembled because of the drag hook can only be attached and because no articulated connections by means of axes and the like are required.
  • the spring element can be designed as a leaf spring, one of which End attacks on the outside of the support lever. Conceivable would of course also be a helical compression spring in certain cases, a coil spring or other spring element. If that Control part is made of plastic material, the leaf spring particularly advantageously formed in one piece with the control part his. Finally, the leaf spring also has a noise-reducing one Effect because they play chatter movements when adjusting prevented.
  • the game also has an advantageous effect on the attachment the fitting on the seating or reclining furniture.
  • FIG. 1 there is essentially a pivot fitting 1 from a locking lever 2, on one side on a joint 22 a pivot lever 6 is articulated. Around this joint leaves the pivot lever relative to the locking lever in the direction of arrow a swing. At a distance from the joint 22 is at another joint 23 a support lever 7 articulated on the pivot lever, the free end 28 is held in a control part 8.
  • the locking lever 2 has an approximately U-shaped configuration in cross section with the two U-legs 3, 3 'and a connecting web 4.
  • the pivot lever 6 is also approximately U-shaped in cross section Profile formed, the profile opening the locking lever 2 faces and the locking lever is made narrower than the pivot lever, so that a complete collapse is possible.
  • the support lever 7 is in the embodiment formed as a closed box girder profile, the Width is smaller than the width between the two U-legs 3, 3 '.
  • the box girder profile can be subjected to a bending operation be produced, one on one side Receives butt seam or it can also be used as a seamless box girder profile be trained.
  • the control part 8 is shown in somewhat more detail in FIG. It consists of a guide section 12 and a control section 13.
  • the guide section 12 carries side guides on both sides 16 for linear guidance in a guideway 9 am Locking lever 2.
  • the side guides can be wedge-shaped on one side bevelled to be inserted into the guideway 9 to facilitate.
  • the control section 13 is with a tow hook 14 provided which engages over a support tongue 17 such that an insertion opening 29 remains free. In between is a push surface 15, the function of which will be explained below.
  • On Spring element 18 in the form of one piece with the control part 8 trained leaf spring extends over the entire length of the control section and beyond.
  • the end 21 of this leaf spring is somewhat rounded to the sliding attack on the To improve the surface of the support lever 7.
  • Another advantage the box-shaped support lever is next to the improvement the stiffness also in that the leaf spring on the closed Surface can slide.
  • the locking lever 2 is Provided with notches 5 over the greater part of its total length. These consist of material deformations from the outside are visible as depressions and which are approximately convex Extend elevations against the inside of the U-shaped profile. As can be seen in particular from FIG. 8, the material deformations are not only on the connecting bridge 4, but also on the two U-legs 3, 3 'arranged.
  • the support lever 7 has a locking edge 19, which is such is trained that they also in the lateral area if possible is supported on the catches 5.
  • the front of the support lever is as Shaped bracket 20, which through the insertion opening 29 behind the Drag hook 14 ( Figure 2) in the control section of the control part 8 can be introduced.
  • the leaf spring 18 exercises with its free End 21 a spring force in the direction of arrow b on the support lever out.
  • the control part 8 is in the direction of arrow c in the guideway 9 displaceable.
  • the guideway is on one side formed by a bevel 10 and by a feed 11.
  • Figure 5 corresponds to one determined support position, as shown in Figure 3 is.
  • the bracket 20 is located in the area of the opening 22 on the control section 3.
  • the pivot lever 6 continues swung open, the locking edge 19 releases from the locking position and the bracket 20 slides up against the force of Leaf spring 18.
  • the bracket 20 remains in the towing position, at which the control part 8 is withdrawn.
  • connection fitting 26 or 27 As can be seen from Figures 3 and 4, the free Ends of the pivot lever 6 and the locking lever 2 snap openings 24 or 25 arranged. These snap-in openings serve each to record a connection fitting 26 or 27, as shown in FIG 9 are shown. With the help of these connection fittings fastening the swivel fitting to a slatted frame.
  • the Snap-in openings simultaneously form a swivel joint for the connection fittings.
  • the pivot fitting is preferably made of cold-formed bent parts made of steel, the surface of which appropriately remunerated. In certain cases, however other materials are also conceivable, in particular also those can be processed by injection molding. In such a In this case, the term "material deformation" has no meaning of cold forming, but of deformation in a mold cavity.
