Definitions

  • the invention relates to a piece of seating furniture with a base fixed in the intended use of the piece of seating furniture, a seat unit with a seat surface and a leg unit with leg support surface which is movable relative to the seat unit.
  • the leg unit is displaceable between a stowage position, in which the leg unit is arranged below the seat surface, and a use position, in which the leg unit is arranged in front of the seat, by means of a movement mechanism.
  • leg unit In order to achieve a sufficiently large leg support surface, there are variants that have a separately movable end segment in addition to the leg unit.
  • the leg unit is pivotable relative to the seat unit, in part by means of double-strap mechanisms.
  • the leg unit closes then usually a pivotable end segment.
  • Documents showing such or similar leg segment and end segment designs include, for example DE 20000633 U1 , the BE 100 91 47 A3 , the DE 10 2008 009 234 A1 and the DE 3718645 C2 , In designs that forego an end segment beyond the leg unit, achieving a sufficiently large leg rest area is more difficult to achieve.
  • the DE 10 2005 001 877 A1 proposes for this a mechanism in which the leg unit is variable in size. It can thereby be reduced in the transfer from the use position to the stowed position below the seat. Only so it is possible to ensure a sufficient size of the leg support surface in the use position and a sufficient reduction of the leg unit in the pivoted stowed position.
  • the object of the invention is to develop a piece of furniture generic type to the effect that this allows the displacement of the leg unit between the stowed position and the use position by means of a simple mechanical design, in particular is desired that the corresponding inventive teaching also in seating furniture pieces with little space under the Seat unit is usable.
  • a piece of seating furniture according to the invention provides a sufficiently large leg support surface without having an end segment which can be displaced against it in addition to the leg unit and without the leg unit having to be made variable in size.
  • the movement mechanism is designed to transfer the leg unit from the stowage position in which the leg support surface is oriented substantially horizontally into the use position, in which the leg support surface is likewise in the Is oriented substantially horizontally.
  • the movement mechanism has an intermediate carrier, which is displaceable by means of a pivoting guide relative to the seat unit or the base, wherein the pivoting guide has at least one first pivoting lever between the intermediate carrier and the seat unit or the base.
  • an inventive piece of seating furniture on a sliding guide with a sliding member wherein the sliding member is translationally guided on the intermediate carrier and wherein the leg unit is mounted on the sliding member.
  • a seating piece of furniture is preferably a padded chair or a cushioned sofa.
  • this may have several separately movable leg units.
  • the notion of high direction means a direction orthogonal to a footprint upon which the furniture stands.
  • the indication of the transverse direction means an extension direction which extends horizontally parallel to the front edge of the seat.
  • the furniture longitudinal direction is a direction orthogonal to the furniture transverse direction and furniture vertical direction.
  • the indications "front” and “rear” refer to the furniture longitudinal direction and refer to the perspective of the person sitting on the piece of furniture, whose legs point forward and whose back points to the rear.
  • the peculiarity of the piece of furniture according to the invention is that it is designed to displace the leg rest largely horizontally.
  • the leg rest at least in the stowage position and in the use position, has the essentially horizontal orientation, by which it is to be understood that the leg support surface does not extend more than 25 ° in each case an imaginary horizontal plane is pivoted.
  • the leg unit is aligned substantially horizontally throughout the process of transfer from the storage state to the use state in this sense.
  • leg unit makes it possible to use a comparatively large leg unit, since this does not enforce a comparatively high seat height on the seat piece of furniture as a result of its length, as in known designs.
  • the length of the legrest in the longitudinal direction may exceed the height of the free space below the seat unit. This also makes it possible to dispense with a separately displaceable relative to the leg unit end segment for extending the leg support surface.
  • This movement mechanism has an intermediate carrier which is pivotally provided on the seat unit or the base.
  • the base is thereby formed by those parts of the piece of seating furniture, which always remains fixed to a substrate on which the piece of furniture is on intended transfer of the piece of furniture from the use position in the stowed position and vice versa.
  • it is a frame to which the feet of the piece of furniture are provided.
  • the seat unit can be movable in the manner explained below.
  • the movement of the intermediate carrier along a circular path can alternatively take place relative to the seat unit or the base.
  • the intermediate carrier itself serves for the translational guidance of a sliding member, which is thereby displaceable in the longitudinal direction of the furniture.
  • levers between the intermediate carrier on the one hand and the base or seat unit on the other hand can be used.
  • these levers have a length between their articulation points of not more than 40 cm, preferably not more than 30 cm.
  • the sliding guide which allows the movement of the leg unit relative to the intermediate carrier, preferably allows a displacement of the leg unit relative to the intermediate carrier of at least 10 cm, preferably of at least 15 cm.
  • a sliding guide according to the invention is a guide of the sliding member relative to the intermediate carrier to understand, which is realized in particular by a sliding guide or a roller guide or by another suitable for the production of a translational Relativverlageriana guide.
  • the translational motion is a linear motion.
  • the displacement of the sliding member relative to the intermediate carrier can serve not only the displacement of the leg unit to the front, but also advantageously allows a pivoting movement of the leg unit relative to the intermediate carrier, which will be explained in more detail depending on the configuration of the seat piece of furniture.
  • the carrier as a whole is firmly connected to the first pivot lever and thus follows in terms of its orientation of the pivoting movement. It is advantageous, however, if the first pivot lever is articulated on the one hand about a pivot axis pivotally mounted on the seat unit or the base and on the other hand, only a second pivot axis is pivotally articulated to the intermediate carrier. In this way it can be prevented that the intermediate carrier pivots to the same extent, in which this applies to the pivot lever. It can therefore be displaced by the pivot guide in the sense of a largely maintaining horizontal alignment of the leg unit, without significantly changing its orientation.
  • positive guidance means are preferably provided by which each pivot position of the first pivot lever relative to the seat unit or relative to the base is caused a pivotal position of the intermediate carrier relative to the first pivot lever.
  • Such positive guidance means thus lead to the desired definiteness of the movement of the subcarrier.
  • this movement is such that the intermediate carrier is pivoted in the transfer position of the leg unit from the stowed position to the use position by not more than 20 °.
  • the pivot guide has a second pivot lever which is pivotally mounted about a first pivot axis spaced from the third pivot axis pivotally mounted on the seat unit or the base and on the other hand to a relation to the second pivot axis spaced fourth pivot axis pivotally hinged on pivoting applications.
  • the pivot guide is designed as a double lever pivot guide.
  • the peculiarity which results from the use of the pivoting guide between the base or seat unit on the one hand and the intermediate support on the other hand and the use of the sliding guide is, in particular, that the intermediate support can for the most part always remain below the seat surface.
  • the movement of the intermediate carrier relative to the seat surface or the base is effected by a pivoting guide, which can be hidden very well in front of the user's eyes.
  • said pivot lever are provided on the outside of the seat relative to the transverse direction. Mechanical components that extend to the left and right of the seat to the front edge of the seat, are considered to be aesthetically disadvantageous and also form considerable opportunities to injure themselves.
  • the sliding guide and the pivoting guide are mechanically independent, so that they can be influenced separately by the user.
  • the pivot guide and the sliding guide are operatively coupled to each other, so that adjusts depending on the relative position of the intermediate carrier relative to the seat unit or the base of a dependent relative position of the sliding member to the intermediate carrier.
  • the movement of the intermediate carrier relative to the seat unit or the base along a circular segment-shaped path indirectly also causes the movement of the sliding member relative to the intermediate carrier.
  • the movement of the sliding member takes place in substantially coincident direction with the movement of the intermediate carrier. While the intermediate support is thus displaced to the front to a lesser extent relative to the base or seat unit, the leg unit is simultaneously displaced forward to a greater extent.
  • control lever which is articulated on the intermediate carrier, the sliding member and the base or the seat unit or on one of the pivot lever.
  • this control lever is preferably mounted about a pivotable in vertical axis on the intermediate carrier.
  • this arrangement with a vertical pivot axis of the control lever causes its pivot points for interaction with the sliding member on the one hand or the base, the seat unit or one of the pivot lever on the other hand along a circular arc shape, so that here intermediate lever may be required.
  • Even such a design with intermediate lever or one instead provide sliding is to be understood as articulation in the sense of the above remarks on the control lever.
  • the proposed control lever is pivoted by the relative movement of the intermediate carrier relative to the seat unit or the base and transmits this pivotal movement on the sliding guide, whereby the sliding member is displaced relative to the intermediate carrier.
  • the leg unit has a pivoting mechanism, wherein this pivoting mechanism is adapted to effect depending on the relative position of the sliding member to the extension pivoting of the leg unit relative to the sliding member.
  • the extension can also serve to improve the tilt stability of the leg unit.
  • both the extension and the sliding member between the seat unit and the leg unit extend and thus in the use position of the leg unit depending on the configuration of the piece of seating furniture are visible to the user, it is considered particularly advantageous if walls of the extension surrounding an interior, within which the sliding member is movably arranged.
  • the sliding member is hidden within the extension.
  • a reverse arrangement is conceivable in which the sliding member defines an interior, within which the extension is arranged.
  • the interior does not have to be completely completed.
