Definitions

  • the invention relates to a upholstered furniture according to the preamble of claim 1.
  • Such upholstered furniture are for example from the US6341392B1 or the DE801527C known and have a base member and a seat member with a seat cushion, which is connected to the base member.
  • the connection between the base member and the seat member is made by guide elements in a manner that allows the seat member to be reciprocated by a combined translational and rotational movement between a first position and a second position.
  • These are preferably in the first position to a seating position in which the upholstered furniture can be used as seating.
  • the second position is preferably a reclining position that allows the upholstered furniture to be used as a sleeping place. In this case, there is regularly the desire to transfer the upholstered furniture in the simplest possible way from one position to the other position.
  • the upholstered furniture should also offer a stable stability, especially in a lying position.
  • this regularly separate support elements must be swung or extended, or it is necessary to move the entire upholstered furniture or only parts of the upholstered furniture on the floor surface.
  • carpets and the like which lie directly on the floor surface from the front of the upholstered furniture, often have a disturbing effect and must first be removed.
  • the invention is therefore based on the object to provide a upholstered furniture, which can be moved back and forth in a simpler manner from a first position to a second position.
  • the upholstered furniture is designed in such a way that a section arranged at least at the rear part of the seat element undergoes an approximately S-shaped trajectory during the movement from the first position to the second position, which results in a support element arranged on the seat element initially being spaced apart moved from the footprint of the base element corresponding floor level in the direction of the front of the upholstered furniture. Only after exceeding a predetermined distance, the support element lowers to the ground level.
  • the support element is preferably rigidly connected to the seat element.
  • the support element can initially be moved over an obstacle, such as a carpet edge, which is located immediately in front of the seating furniture during the movement.
  • an obstacle such as a carpet edge
  • the support member When the support member is lowered onto the carpet after passing the carpet edge, the support member may move on the carpet as on a normal floor surface.
  • the support element is here preferably designed as a support roller, so that a rolling of the support member on each substrate is possible without it depends on the sliding properties of the support member on the respective substrate.
  • the upholstered furniture preferably has a lower guide element. This is preferably arranged on the base element. Particularly preferred are two lower guide elements, which are arranged in parallel. Two lower guide elements lead to a stabilization of the upholstered furniture.
  • An advantageous design of the upholstered furniture which enables the movement of seat element and support element according to the invention, relates in particular to the design of the guide elements.
  • the design of the guide elements, the relative movement of the seat member to the base member can be selectively influenced, in particular, a superposition of the substantially translational movement of the seat member to the front side, ie forward, by a rotational movement possible. This can be effected in an advantageous manner by curvatures of a guide element.
  • the portion arranged at the rear part of the seat element is a rigid connecting element between the seat element and a guide counter element, which is guided in the lower guide element.
  • the combination of translational with the Rotational movement can be generated by the fact that the translational movement takes place first along a guide element.
  • the arranged on the rear part of the seat member portion is additionally movably coupled to a connecting element.
  • the connecting element in turn is guided with the free end by means of a guide counter-element on the lower guide element.
  • the connecting element is rotated about the guide counter-element, so that in total the section arranged at the rear part of the seat element performs an approximately S-shaped movement.
  • the upholstered furniture preferably has a back element carrying a backrest cushion.
  • This is advantageously hinged to the seat member and the base member such that it is also reciprocated from the first position to a second position by the movement of the seat member in a combined translational and rotational movement relative to the base member.
  • the useful surface of the backrest cushion In the first position, which is advantageously a seating position, the useful surface of the backrest cushion is preferably in a slightly inclined backwards, but substantially upright position.
  • the useful surface of the pad of the back element is preferably in an at least substantially horizontal position.
  • the upholstered furniture in particular the articulated connection of the back cushion with the seat element and the base element is designed so that the back element in the first position has the smallest distance to the back of the upholstered furniture.
  • the first position is preferably an end position of the movement region of the back element.
  • upholstered furniture of the type in question often has to be removed from the wall in order to allow a change in the position of the elements of the upholstered furniture, in particular a transfer from a sitting position to a lying position.
  • this is awkward for the user and thus disadvantageous.
  • the upholstered furniture has a drive for moving the seat element.
  • This drive is preferably a linear drive.
  • spindle drives can be used here, these are characterized in particular by the fact that they can handle comparatively large forces. This also makes it possible, in particular, to change the position of the upholstered furniture, in particular of the seat element, while a person uses the upholstered furniture.
  • Such drives are powerful enough to move the seat member with a lying or sitting on this person.
  • Such, in particular electric drive can also be used in a simple and elegant way, especially if the necessary controls are hidden by cushions attached.
  • the padding element has a footrest element.
  • a foot support element serves to deposit the feet and is preferably also movable back and forth between a use position and a non-use position. In its non-use position, the effective area of the footrest element preferably takes an in Essentially vertical position, while the footrest element occupies a position in particular in its use position, in which the useful surface, at least substantially, is aligned horizontally.
  • the footrest member is preferably attached to the seat member, which has the advantage of moving in concert with the seat member as the seat member is moved.
  • the footrest element is designed such that it can be moved between the use position and the non-use position via one or a plurality of intermediate positions; in a preferred stepless adjustment of the footrest element this is actually an arbitrary multiplicity of intermediate positions.
  • Such intermediate positions have the advantage that in addition to the use position further possible positions are generated in which the feet can be stored in alternative positions.
  • the upholstered furniture preferably has a footrest drive.
  • it can preferably be a linear drive, in particular a spindle drive.
  • the footrest drive serves to move the footrest between its use position and its non-use position.
  • the preferably electric footrest drive preferably has control elements assigned to it, with which it can be actuated independently of the rest of the upholstered furniture, in particular the control of other drives of the upholstered furniture. This allows the user to combine different positions of the foot support member with different positions of the seat member and advantageously also the back member together, which increases the versatility of the upholstered furniture.
  • the upholstered furniture is advantageously designed such that the seat element passes through a third position on its path of movement between the first position and the second position.
  • This third position is preferably a relaxation position.
  • This is understood to mean, in particular, a position in which the useful surface of the seat element or the upholstery of the seat element drops toward the back of the upholstered furniture or falls more sharply than in the first and / or the second position. It is advantageous if the passage through the third position is also performed by the back element, which has a greater inclination of its effective area in the third position than in the first position.
  • the movement between the first position and the second position is preferably a stepless movement, that is to say that an unspecified plurality of corresponding intermediate positions are passed through. This makes it possible, in the selection of the third position by the user of the upholstered furniture, to select a third position which best suits his current needs.
  • each guide element cooperates with at least one guide counter-element.
  • the guide counter element is preferably a guide roller.
  • a particularly advantageous combination of a guide rail with a C-shaped cross section and a guide roller has the particular advantage that the Guide elements may have curvatures. Such curvatures make it easier to realize the movement sequences according to the invention.
  • the lower guide element and the lower guide elements on two opposite bends. These preferably give the guide element an at least approximately S-shaped profile.
  • Such a course makes it possible to bring about the movement of the seat element according to the invention, in particular to ensure that the seat element firstly experiences a lowering of the rear area of its usable area during its forward movement, which is then raised again after passing the rear bend by the guide counter element ,
  • the seat member By raising the rear portion of the seat member, the seat member preferably performs a tilting forward rotational movement, which in particular causes the support member is lowered to the ground level.
  • the lower guide element preferably has an approximately horizontal to the front of the upholstered furniture, possibly slightly sloping course. During the movement over this route section, the support element is preferably already in contact with the ground.
  • a guide rail with a C-shaped cross section and at least one guide roller has the particular advantage that the sequence of movement of at least the rear part of the seat member arranged portion which is arranged in this embodiment to a connecting element, are divided into two parts can. Initially, the arranged portion moves forward parallel to the guide member.
  • the connecting element which is at both ends is movably mounted, forcibly guided by means of a second lower guide counter element, which is also guided in the guide element.
  • a third lower guide counter-element is attached to the connecting element so that it rolls on the latter during the movement along the guide element.
  • the third lower guide counter element is preferably, viewed from the first guide counter element, arranged behind the second lower guide element. This arrangement stabilizes the positive guidance, in particular in the front portion of the guide element.
  • the seat element undergoes a lowering of the rear portion of its effective area during its forward movement, which is based on the fact that the guide element is also lowered towards the front.
  • the guide element can be straight or slightly curved.
  • the first guide counter element abuts against the end boundary of the guide element.
  • the C-shaped guide element is recessed in the region of the second lower guide counter-element upwards, so that the connecting element, with the arranged at the rear of the seat member portion and the arranged second, and optionally third, lower guide counter-element, around the first lower guide member can turn upwards and so continues the approximately S-shaped movement of the arranged portion and thereby lowered the support element to the ground level.
  • a guide aid is mounted on the guide element immediately adjacent to the recess, which supports the second lower guide element at least in sections during the rotational movement of the connecting element.
  • the guide aid which is preferably arranged in front of the recess for the second lower guide counter-element, are provided with a ramp on which the third lower guide counter-element in the last portion of the translational movement initiates the rotational movement of the connecting element by being guided up the ramp ,
  • the upholstered furniture preferably has an upper guide element arranged above the guide element. It is understood that the upholstered furniture advantageously also has two upper guide elements. These are preferably arranged in pairs in the lateral regions of the upholstered furniture in its width direction. The upper guide element or the two upper guide elements are preferably arranged on the seat element. The corresponding guide counter-element is preferably located in the front region of the base element.
  • the upper guide element has a straight course.
  • the upper guide element particularly preferably faces the front side of the upholstered furniture at a greater distance from the useful surface of the seat element than towards the rear side of the upholstered furniture. This results in a slight lowering over the movement path of the seat element, which is advantageous with regard to the overall movement guidance, in particular to the lowered position of the support element in the second position.
  • FIGS. 1 to 11 illustrated exemplary upholstered furniture 1 comprises a base element 2, a seat element 3 and preferably a back element 4.
  • the seat element 3 has, for example, a structural element 20 and a padding element 21.
