Definitions

  • the present invention relates to a swivel fitting, in particular for movable furniture parts on seating or reclining furniture according to the preamble of claim 1 and a piece of furniture.
  • a generic swivel fitting is, for example, from DE 10 2017 110 253 A1 known.
  • two levers can be fixed relative to one another via a clamping mechanism.
  • One of these levers can be attached to a base body or seat part of upholstered furniture, while the second lever serves to fix a pivotably mounted headrest, armrest, footrest or another furniture part pivotably mounted on the base body or seat part of the furniture.
  • the pivotable furniture part can be pivoted from an initial position into a predetermined pivoted position and fixed in this pivoted position.
  • the swivel fitting is designed in such a way that the furniture part to be adjusted can be adjusted from any swivel position without the two levers first having to be swiveled back into the basic position.
  • overload clutches are relatively expensive to manufacture.
  • overload clutch has to be re-engaged at the point at which it disengaged, or at least can only be re-engaged in a shifted grid.
  • DE102017110253 A1 discloses a swivel fitting according to the preamble of claim 1.
  • the object of the present invention is to further develop a swivel fitting of the generic type such that the swivel fitting is also protected against overload in a simple and cost-effective manner.
  • a further object of the invention is to provide a piece of furniture with which the functioning of a piece of furniture with movable components is further improved.
  • the first object is achieved by a swivel fitting with the features of claim 1.
  • the second object is achieved by a piece of furniture with the features of claim 12.
  • the swivel fitting according to the invention has at least one first lever, which is mounted around a force shaft serving as the axis of rotation and can be swiveled out of a basic position by a predetermined angle relative to the latter.
  • the swivel fitting also has a clamping mechanism with which the first lever can be fixed in different angular positions within the predetermined angle relative to the power shaft.
  • This clamping mechanism has a toothed ring disk placed on the power shaft with external teeth formed on the outer edge and a pawl pivotally mounted on the first lever and loaded in the direction of the external teeth, which in a detent position engages with the external teeth of the toothed ring disk.
  • the clamping mechanism also has a first control disk, which is rotatably mounted around the power shaft and with which the at least one pawl can be disengaged from the toothing in an adjustment direction after the predetermined angle has been traversed from the basic position, so that when the pawl is disengaged from the toothing by crossing the predetermined angle in a return direction, the first lever can be pivoted back into the basic position relative to the power shaft.
  • At least one friction disk arranged on the power shaft in a rotationally fixed and axially secured manner is pushed onto the annular gear disk, the annular gear disk is held frictionally on the at least one friction disc up to a predetermined torque against rotation about the axis of rotation.
  • an overload safety device that is easy to assemble and inexpensive in terms of its components is made possible, with which the power shaft is decoupled from the toothed ring disk and thus the power shaft from the first lever in the event of an overload.
  • the first lever can be pivoted relative to the power shaft without damaging the clamping mechanism.
  • an inner peripheral edge of the toothed ring disk is conically shaped and pushed onto a cone arranged on the power shaft.
  • the at least one friction disc is pressed against the annular gear disc on the side of the smaller diameter of the inner peripheral edge of the annular gear disc.
  • the cone arranged on the power shaft and the friction disk press the friction disk arranged non-rotatably on the power shaft and the annular gear disk together in such a way that the predetermined torque defining the overload limit must be exceeded for the relative rotation of the friction disk to the annular gear disk.
  • the resilient pressure force of the friction disk creates friction on the cone and on the contact surface of the toothed ring disk.
  • the predetermined torque can be defined depending on the selected pressure force or coefficient of friction between the contact surface of the toothed ring disk on the friction disk and the predefined cone angle.
  • the cone is formed in one piece on the power shaft, which enables extremely simple assembly.
  • the cone is mounted on the power shaft.
  • the power shaft itself and the cone to be produced as an individual component, for example as a sheet metal element, can be produced very inexpensively.
  • the cone is designed as a radially slotted clamping ring.
  • the cone angle of the cone is between 15° and 35°, particularly preferably between 20° and 30°.
  • a friction disk arranged in a rotationally fixed and axially secured manner is pushed on on both sides of the toothed ring disk.
  • a plurality of toothed ring disks are placed on the power shaft, with a friction disk held non-rotatably on the power shaft being arranged between two toothed ring disks.
  • two toothed ring disks are used with a friction disk arranged between them.
  • the force exerted by the friction disks which are fixed and/or pressed onto the power shaft in a rotationally fixed manner thus creates friction at six contact points (in the case of three toothed ring disks) or four contact points (in the case of two toothed ring disks used), via which the torque provided for the overload protection can be adjusted .
  • the wear and the overload torque can be set in a simple manner via the spring force and pressing depth of the friction discs used and the number of toothed ring discs used.
  • a tab is formed on the first control disk, which extends perpendicularly to the plane of the first control disk axially to the power shaft outwards into a recess provided for this purpose in a recess of the first lever.
  • a recess is formed on an outer edge of the friction disk, in which a switching element is accommodated so that it can pivot about a switching angle in the plane of the friction disk.
  • This switching element also serves as an alternative to the combination of the control pin arranged on the first lever and the recess in the first control disk.
  • the friction disk accommodating the switching element has a thickness, in the axial direction of the power shaft, which is greater than the thickness of the switching element.
  • the at least one friction disk is pressed onto the power shaft with a press fit against the annular gear disk.
  • the friction disk is designed as a plate spring.
  • a switching contour is formed on an outer edge of the friction disk.
  • the predetermined torque up to which the toothed ring disk is frictionally held against rotation about the axis by the at least one friction disk is at least 70 Nm, preferably at least 80 Nm.
  • a particular advantage of the arrangement according to the invention is that the swivel fitting enables a maximum adjustment angle of approximately 250°. This is made possible by the arrangement of the control bolts and the stops as well as the internal structure with the toothed ring disc, the control disc and the pawl.
  • a second lever is coupled to the power shaft in a rotationally fixed manner.
  • the furniture according to the invention is characterized by a swivel fitting as described above.
  • the second lever is part of the adjustable furniture part.
  • top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the swivel fitting, lever, toothed ring disk, pawl, power shaft, cone, selected in the respective figures. the friction disk and the like. These terms are not to be understood as limiting, i.e. these references can change due to different working positions or the mirror-symmetrical design or the like.
  • figure 1 is denoted by the reference numeral 1 as a whole an embodiment of a swivel fitting according to the invention.
  • Such a swivel fitting 1 is used in particular to enable a swiveling movement of movable furniture parts on furniture, such as an armrest 103 or a backrest 102, headrest or footrest of a piece of furniture 100 designed as seating or lying furniture, as is exemplified in figures 27 and 28 is shown.

  • the second lever 3 can also be part of a piece of furniture which is placed directly on the power shaft 6 .
