Definitions

  • the present invention relates to a swivel fitting, in particular for adjustment segments on furniture according to the preamble of claim 1, and a piece of furniture.
  • Such swivel fittings are used in furniture, in particular in upholstered furniture, for example sofas, armchairs or beds, in order to be able to swivel various adjustment segments such as armrests, headrests or the like relative to a body of the furniture.
  • Such swivel fittings usually have locking or latching mechanisms that enable such a swivel fitting to be fixed in intermediate positions.
  • the spring is supported with a first end on one in the sides of the cover, which in turn is rotatably coupled to a first lever, while a second end of the spring is rotatably coupled to the second lever.
  • the object of the present invention is to further develop a swivel fitting of the generic type in such a way that no second lever is necessary to support the spring.
  • the pivot fitting according to the invention has a first lever which is pivotably mounted on a bearing shaft.
  • the swivel fitting also has a fixing mechanism with which the lever can be fixed in different angular positions within a predetermined angle relative to the bearing shaft.
  • the swivel fitting also has a spring for transmitting a torque to the lever.
  • the first end of the spring is coupled to the lever and a second end of the spring is non-rotatably coupled to the bearing shaft.
  • a support element to which the first end of the spring is coupled, projects from a side of the first lever facing the spring.
  • this support element can be designed as a pin protruding in the direction of the spring.
  • the support element is also conceivable to design the support element as a portion of a lever head of the lever that projects in the direction of the spring.
  • the section can be bent out of the material of the lever head or integrally formed thereon.
  • the support element is designed as an end, projecting in the direction of the spring, of a retaining bolt of a latching pawl of the fixing mechanism that is pivotably mounted on the first lever.
  • the latching pawl is in a latching position of the swivel fitting in engagement with a toothing of the bearing shaft for the rotationally fixed fixing of a second lever or a furniture segment that can be pivoted relative to the first lever.
  • the bearing shaft has a central opening in which a bolt is received.
  • the second end of the spring is preferably designed as a polygonal receptacle.
  • the bolt has a first neck section designed as a polygon, which is received in a rotationally fixed manner in the second end of the spring designed as a polygonal receptacle.
  • the bolt has a second neck section designed as a polygon which is received in a rotationally fixed manner in the central opening of the bearing shaft designed as a polygonal receptacle.
  • the second end of the spring is coupled in a simple manner to the bearing shaft in a rotationally fixed manner via the bolt.
  • a polygon is formed on a bearing shaft as an extension of the central opening and is received in a rotationally fixed manner in the second end of the spring, which is designed as a polygonal receptacle.
  • the bolt has a cylindrical neck section which is received in a cylindrical central opening in the bearing shaft and in this case only serves to axially fix the spring on the swivel fitting.
  • the furniture according to the invention with a body and an adjustment segment held pivotably on a body is characterized in that the adjustment segment is attached to the body via at least one pivot fitting as described above.
  • the reference numeral 1 denotes an embodiment variant of a swivel fitting according to the invention. All design variants Such a swivel fitting 1 are used in particular to swivel adjustment segments 82 relative to a furniture body 81 of a piece of furniture 8, as shown in FIG Figure 15 is shown by way of example.
  • the lever arm 21 of the first lever 2 (and, if present, the lever arm 31 of the second lever 3) has several bores that allow screws to pass through for fastening the lever 2, 3 to parts of the furniture 8 that can be pivoted relative to one another .
  • the first lever 2 is designed in two layers in all of the illustrated embodiments, with a fixing mechanism 7, for example in the form of a latching mechanism, being received between lever heads 22 of the first lever 2 that are cranked away from one another.
  • a fixing mechanism 7 for example in the form of a latching mechanism
  • the shown first variant of a swivel fitting 1 according to the invention has, in addition to the first lever 2, a second lever 3, a spring 4, preferably in the form of a spiral spring, which is attached via a bolt 5 on a side of the lever head 22 of the first lever 2 facing away from the second lever 3 is arranged.
  • the bolt 5 has a head 54 which rests on an outside of the spring 4 facing away from the first lever 2.
  • the bolt neck which in the variant shown here consists of a cylindrical neck section 51 and two polygonal neck sections 52, 53, penetrates in the assembled state a second end 42 of the spring designed as a polygonal receptacle, an opening 63 of a bearing shaft 6 and an opening in one Disk 12, the bolt 5 together with the disk 12, the components of the swivel fitting 1 axially to an axis of rotation D of the first lever 2 and the Bearing shaft 6 fixed.
  • the head 54 of the bolt 5 covers at least the second end 42 of the spring 4, which is designed as a polygonal receptacle.
  • the bearing shaft 6, which is partially received in the lever head 22, has a first radial toothing 61 for non-rotatable fixation in a toothed ring 32 of the second lever 3, as well as a second radial toothing 62 received within the lever head 22, which is coupled to the fixing mechanism 7.
  • the fixing mechanism 7 serves to fix the first lever 2 in different angular positions within a predetermined angle ⁇ relative to the bearing shaft 6.
  • axial toothing can also be used as a coupling-in form fit between components.
  • a clamping mechanism based on a frictional connection is also conceivable.
  • a support element 11 designed as a pin protrudes from the lever head 22.
  • the first end 41 of the spring 4 embodied here as a spiral spring, is hook-shaped with an end piece 43 bent at an angle, or else in an arcuate outlet that engages around the support element 11 in the functional position.
  • the second end 42 of the spring 4 is designed here as a polygonal receptacle in which a polygonal first neck section 53 of the bolt 5 is received.
  • the second end 42 of the spring 4 is thus rotatably coupled to the bearing shaft 6 and the first end 41 of the spring 4 is supported on the support element 11 on the first lever 2, so that a corresponding torque of an unintentional pivoting of the first lever 2 relative to the bearing shaft 6 and thus in the case of a second lever 3 arranged non-rotatably on the bearing shaft 6 counteracts this.
  • the in Figure 2 The exemplary fixing mechanism 7 shown has two latching pawls 71, 72 which are pivotably mounted on the lever head 22 of the first lever 2 via retaining bolts.
  • One of these retaining bolts extends outward through a bore in the lever head 22 in the direction of the spring 4 and thus forms the support element 11 for the first end 41 of the spring 4.
  • the latches 71, 72 serve to fix the swivel fitting 1 in a predetermined latching position or to release the bearing shaft 6 relative to the first lever 2 when the swivel fitting 1 moves back.
  • a polygon 64 formed on the bearing shaft 6 protrudes from the lever head 22 of the first lever 2 in extension of the central opening 63 and rotatably in the end 42 of the spring 4 designed as a polygonal receptacle is recorded.
  • the bolt 5 merely serves to axially fix the spring 4 on the first lever 2.
  • the end of the bearing shaft 6 facing away from the spring 4 is in turn coupled non-rotatably to a second lever 3 via the first radial toothing 61, as shown in FIG Figure 6 is shown.
  • FIGS. 7 and 8th show an embodiment of a swivel fitting 1 with only the first lever 2.
  • the bearing shaft 6 protrudes from the lever head 22 on the side of the first lever 2 facing away from the spring 4 so far that the radial toothing 61 is positioned outside the lever head 22, so that a corresponding coupling element of an adjustment segment of a piece of furniture can be connected directly to this radial toothing 61.
  • the support element 11 is designed as a pin which projects in the direction of the spring 4 and is mounted on the lever head.
  • the support element 11 is also conceivable to design the support element 11 as a section of a lever head 22 of the lever 2 protruding in the direction of the spring 4.
  • a polygon 65 of the bearing shaft 6 designed as a polygon or toothed ring protrudes from the lever head 22 in the direction of the spring 4.
  • the central opening 63 of the bearing shaft 6 is again designed as a polygon, in particular as a square, and serves to accommodate the second neck section 52 of the bolt 5, which is designed as a square.
  • Figure 10 shows an example of the coupling of the first end 41 of the spring 4 via the bent end piece 43 to the support element 11 on the lever head 22 of the first lever 2.
  • FIGS. 9 and 10 Another embodiment variant shown of a pivot fitting 1 shows two lever arms 2, 3, corresponding to the embodiment variant of the pivot fitting 1 shown in FIGS. 9 and 10.
  • the bearing shaft 6 At its end facing the spring 4, the bearing shaft 6 in turn has an end piece 64 that matches the shape of the polygon receiving the second end 42 of the spring 4 and that connects to a polygon 65 of the bearing shaft 6 which is designed as a polygon or a toothed ring and which faces the spring 4 protrudes from the lever head 22 of the first lever 2.
  • FIGS. 13 and 14th finally show an embodiment variant of a swivel fitting 1 according to the invention, which essentially corresponds to that in Figure 11 and 12 the embodiment variant shown, only without a second lever 3.
  • the Figure 15 shows an exemplary structure of a piece of furniture 8 and a body 81 and an adjustment segment 82 pivotably held on the body 81, the adjustment segment 82 being pivotably held on the body 81 of the piece of furniture 8 via such a pivot fitting 1.
