Definitions

  • the present invention relates to a reclining piece of furniture with a reclining part that can be pivoted in a horizontal plane between a first position and a second position with respect to the support frame of the reclining furniture on which the reclining part is mounted.
  • the reclining furniture therefore offers two different configurations, which enable the reclining part to be aligned differently depending on your needs.
  • the reclining furniture is part of a larger couch seating group in which the reclining part of the reclining furniture adjoins a seat part of an adjacent seating unit of the couch seating group, the difficulty may arise that that side of the reclining part that adjoins the adjacent seating part collides with it if the lying part is pivoted between the first position and the second position.
  • the invention is therefore based on the object of providing a reclining piece of furniture of the type mentioned, the reclining part of which can be pivoted without collision if the reclining piece of furniture is, for example, part of a larger couch seating area.
  • a link guide with two non-parallel guide rails is effectively coupled between the reclining part and the support frame, in each of which there is a guide element such as a glider or a roller is guided, with either the guide rails being attached to the support frame and the guide elements to the lying part or the guide rails to the lying part and the guide elements to the support frame.
  • the lying part does not pivot about a fixed axis of rotation when pivoting, which would otherwise result in the collision problem described above. Due to the fact that the guide elements are guided in the two non-parallel guide rails, the lying part is rotated about a fictitious axis of rotation when the lying part is pivoted between the first position and the second position, with the position of the said fictitious axis of rotation shifting, when the lying part is pivoted. The lying part therefore always rotates around a different axis of rotation, depending on the pivoting position.
  • the fictitious axis of rotation of the reclining part can be shifted in such a way that that side of the reclining part that adjoins an adjacent seat part of a larger couch seating group is pivoted when the reclining part is pivoted in such a way that there is no collision with the adjacent seat part.
  • the two guide rails are arranged and aligned with one another in such a way that at least one corner of the lying part, viewed in plan view, is always on or within the outline of the support frame, both in the first and second positions of the lying part as well as in any pivoting positions between the first and second positions. Since the at least one corner of the reclining part always remains on or within the outline of the support frame, it cannot undesirably collide with any adjacent seat parts or other components of a larger couch seating group.
  • the shape, position and orientation of a guide rail of the two guide rails can correspond to the trajectory of a guide element of the two guide elements between the first position and the second position and the shape, position and orientation of the other of the two guide rails can also viewed in plan view correspond to the trajectory of the other of the two guide elements between the first position and the second position.
  • the shape, position and orientation of the two guide rails one can, for example, proceed in such a way that two spaced-apart guide elements are first mounted, for example, on the underside of the lying part. The lying part can then be brought into a position above the support frame that corresponds to the first position of the lying part. In this state, no guide rails are yet provided on the support frame.
  • the two guide elements each describe one Trajectory that has a specific shape, location and orientation. If guide rails corresponding to the shapes of the two path curves are now attached to the support frame in such a way that their position and orientation correspond to the respective position and orientation of the respective path curve, the lying part can then be coupled to the support frame by placing the guide elements in the respective guide rail can be inserted.
  • the lying part is now pivoted on the support frame between its first and its second position, then in the desired manner the at least one corner of the lying part always remains on or within the outline of the support frame, since the two guide rails have the same shape, position and orientation Trajectories of the two Guide elements correspond, so that the at least one corner always remains on or within the outline of the support frame.
  • one of the two guide rails runs parallel to a short side of the support frame or the lying part and the other of the two guide rails runs parallel to a long side of the support frame or the lying part and thus perpendicular to that guide rail which is parallel runs to the short side of the support frame or the lying part.
  • the two guide rails can advantageously be designed as straight guide rails. Depending on the position of the two guide elements, however, they may also describe curved paths, which means that the two guide rails must be designed and arranged according to such curved paths.
  • the lying part has a head end and a foot end, with the link guide being located closer to the head end than to the foot end.
  • the foot end of the lying part In the first position, the foot end of the lying part is located on or within the outline of the support frame when viewed from above, whereas in the second position, pivoted through 90°, the foot end of the lying part is located outside the outline of the support frame when viewed from above.
  • the lying part In the first position, the lying part can be located completely above the support frame, whereas in the second position the lying part projects with its foot end over the support frame, so that the foot end is, so to speak, "in the air”.
  • the lying part has a slider with a sliding surface on its underside and the support frame on its top has a counter slider with a counter sliding surface on which the sliding surface of the slider rests both in the first and second positions of the lying part as well as in any pivoting positions in between.
  • the slider and the counter-slider can, for example, be coated with a material with a low coefficient of friction as a sliding surface or counter-sliding surface in order to keep the friction between the slider and the counter-slider and thus wear low.
  • Both the first position and the second position can be defined by the ends of the two guide rails;
  • the reclining furniture can also have a first and a second fixed stop, with the slider of the reclining part in the first position with the first stop and in the second Position comes into contact with the second stop. Because the slider rests against the respective stop, the lying part cannot be pivoted beyond the respective position (first position or second position), which could otherwise result in overstressing of the guide elements.
  • the reclining furniture further has a first and a second fixed ramp, the sliding surface of the slider of the lying part before or when reaching the first position on the first ramp and before or when reaching the second position runs onto the second ramp. If, for example, the lying surface is pivoted by an operator from its first position into its second position, the sliding surface does not suddenly impact the second stop; Rather, the operator receives haptic feedback due to the slider running onto the second ramp, which informs the operator that the second stop or the second one will soon be reached position is announced. The operator therefore knows that the second position will soon be reached and can therefore reduce the force required to pivot the lying part accordingly so that the glider does not strike with force against the second stop, which would otherwise damage the glider and/or the respective stop could lead.
  • the stops and the ramp can be designed as separate components; According to a preferred embodiment, however, it can be provided that the first stop is formed in one piece with the first ramp and the second stop is formed in one piece with the second ramp.
  • the guide elements each comprise a roller, the respective roller being arranged in an associated guide rail and guided by it.
  • the two guide rails can each form a guide channel and a slot through which the respective guide element extends with its roller ahead into the guide channel and whose clear width is smaller than the diameter of the respective roller. Because the clear width of the slot in question is smaller than the diameter of the respective roller, it is held captively in the guide rail or in the guide channel.
  • roller guidance of the guide elements not only reduces the friction between the guide elements and the associated guide rails; Rather, due to the fact that the rollers are captively guided in the respective guide rail, the lying surface is also secured against lifting forces, so that the lying surface cannot tip over, especially in the second position.
  • the guide rails, the stops and the ramps can be attached to the support frame using suitable fastening means such as cross beams, trusses or support arms; According to a preferred embodiment, however, it can be provided that the support frame has a rectangular plate which forms the rectangular outline of the support frame, with the guide rails and / or the counter slider and / or the two stops and / or the two on the top of this plate ramps are attached.
  • the plate in question not only serves to attach the components in question to the support frame, but also serves as a kind of table or storage surface in the second position of the lying surface, since in this position the plate is not completely covered by the lying surface .
  • the lying surface can be secured against lifting forces by the rollers that are captively guided in the guide rails;
  • an arcuate slot can be formed in the plate, through which a securing element attached to the underside of the lying part extends.
  • the securing element can have a securing part at its free end below the plate, which has a larger cross-sectional dimension than the arcuate slot, so that the securing element and thus the lying part cannot be lifted. Since the securing element in question also describes a specific trajectory when the lying part is pivoted between its first and second positions, the arcuate slot has a shape that describes the securing element when pivoting between the first and second positions.
  • the reclining furniture 10 has a substantially rectangular support frame 12, which is supported on the one hand at the foot end via supports 14 on the floor and on the other hand at the head end by means of hooks 16 on an adjacent seat part (not shown) of a larger couch seating group, to which the Reclining furniture 10 belongs.
  • the support frame 12 in turn supports a substantially rectangular lying part 18 with two short sides 20 and two long sides, which includes a slatted frame 28 and a cushion 26 resting thereon.
  • the slats of the slatted frame 28 are not shown here for the sake of clarity, but the slat holders are 30.
  • the reclining furniture 10 according to the invention includes a back part or a backrest 24, the inclination of which can be adjusted.
  • the lying part 18 is pivotally mounted on the support frame 12, by means of a complex link guide 35, which allows the lying part 18 in a horizontal plane with respect to the support frame 12 between a first position according to Figures 1 and 2 and a second position according to Figures 3 and 4 to pivot by 90°.
  • the link guide 35 which will be explained in more detail below, is located closer to the head end 32 than to the foot end 34.
  • the foot end 34 of the lying part 18 is in the first position on or within the outline of the rectangular support frame 12, whereas it is in the second position outside the outline of the support frame 12.
  • the link guide 35 is designed so that the corner 22 of the lying part 18 is always on or within the outline of the support frame 12 when it is pivoted.
  • the link guide 35 includes two non-parallel guide rails 36, 38, which are attached to the top of a rectangular plate 13 of the support frame 12.
  • the first guide rail 36 runs parallel to the short side 20 of the support frame 12, which adjoins the adjacent seat part (not shown here), whereas the second guide rail 38 runs parallel to the long side of the support frame 12 and thus perpendicular to the first guide rail 36.
  • the guide link 35 includes two guide elements 40, 42 attached to the underside of the lying part 18, which are slidably guided in the first and second guide rails 36, 38, respectively. Contrary to the embodiment described, it is also possible to attach the two guide rails 36, 38 to the underside of the lying part 18 and the two guide elements 40, 42 to the top of the plate 13 of the support frame 12.
  • the first guide element 40 is located at the end of the first guide rail 36, which is shown in the top view of the Fig. 1 located near corner 22.
  • the second guide element 42 is located at the end of the second guide rail 38, which adjoins the first guide rail 36.
  • the lying part 18 is starting from the in the Fig. 1 shown first position clockwise in the direction of its in the Fig. 3 shown second position pivoted, the first guide element 40 in the first guide rail 36 is moved to the opposite end of the first guide rail 36 and the second guide element 42 in the second guide rail 38 is moved to the opposite end of the second guide rail 38.
  • This displacement of the two guide elements 40, 42 has the desired result that the front corner 22 of the lying part 18 does not collide with an adjacent seat part (not shown) when the lying part 18 is pivoted. Due to the described Arrangement of the two guide rails 36, 38, the front corner 22 of the lying part 18 moves along the short side 20 of the support frame 12 during the pivoting of the lying part 18, so that there can be no collision with an adjacent seat part.
  • the guide rails can also have any shape, position and orientation.
  • the shape, position and orientation of the guide rails 36, 38 must be chosen so that, given the position of the guide elements 40, 42 on the underside of the lying part 18, they correspond to the trajectory of the respective guide element 40, 42 when the lying part 18 is out of its first position is pivoted into its second position.
  • the procedure can be, for example, that first, for example, two spaced-apart guide elements 40, 42 are mounted on the underside of the lying part 18.
  • the lying part 18 can then be brought into a position above the support frame 12 that corresponds to the first position of the lying part 18. If the lying part 18 is now pivoted from this first position into its second position, for example by 90 °, so that the corner 22, viewed in plan view, moves along the short side of the support frame, the two guide elements 40, 42 each describe a trajectory , which have a specific shape, location and orientation.
  • the lying part 18 can then be used can be coupled to the support frame 12 by inserting the guide elements 40, 42 into the respective guide rail 36, 38 become. If the lying part 18 is now pivoted on the support frame 12 between its first and second position, the corner 22 of the lying part 18 always remains in the desired manner on the short side of the support frame 12, since the two guide rails 36, 38 have the same shape , position and orientation correspond to the previously determined path curves of the two guide elements 40, 42, so that the corner 22 moves along the short side of the support frame 12.
  • the previously explained link guide 35 guides the pivoting movement of the lying part 18 in the desired manner so that the front corner 22 of the lying part 18 always remains on or within the outline of the support frame 12; So that the lying part 18 and in particular its slatted frame 28 does not scratch the support frame 12 and in particular its plate 13 when pivoting, two rod-shaped sliders 48 are attached to the underside of the lying part 18, which rest with their sliding surface on the counter-sliding surface of a counter-glider 49, which on the top of the plate 13 of the support frame 12 is attached.
  • the two sliders 48 and the counter-slider 49 are aligned with one another in such a way that the counter-slider 49 rests on the counter-slider 48 both in the first and in the second position.
  • the two guide rails 36, 38 each form a guide channel 58 and a slot 60 extending along the respective guide rail 36, 38, through which the respective guide element 40, 42 extends into the guide channel 58.
  • a roller 44, 46 arranged in the respective guide channel 58, the diameter of which is larger than the clear width of the slot 60.
  • the respective roller 40, 46 is therefore captive in the respective guide rail 36 , 38 held and in particular cannot be pulled out upwards to prevent the lying part 18 from being in the second position according to Figures 3 and 4 can tip.
  • two stops 50, 52 are also attached to the plate 13 of the support frame 12, on which a slider 48 of the lying part 18 is in the first or in the second position of the lying part 18 is present.
  • the two stops 50, 52 are each formed in one piece with a respective run-up slope 54, 56, on which the sliding surface of the slider 48 runs shortly before reaching the first or second position.
  • an operator pivoting the lying part 18 not only receives haptic feedback to the effect that the first or second position of the lying part 18 is about to be reached; Rather, the respective slider 48 rests in the first or second position on a bearing level 64, which extends between the respective stop 50, 52 and the respective run-up slope 54, 56, see the Fig. 6 .
  • the lying part 18 rests with a slider 48 both on the counter slider 49 and on the bearing surface 66, which is formed in one piece with the first stop 50.
  • the lying part 18 rests in the second position with its slider 48 both on the counter slider 49 and on the bearing level 64, which is formed in one piece with the second stop 52.
  • an arcuate slot 62 is also formed in the plate 38, through which a securing element 66 extends. which is attached to the underside of the lying part 18.
  • the arcuate slot 64 describes the same trajectory as the securing element 66 when pivoting the lying part 18 between the first and second positions.
  • the arcuate slot 62 and the securing element 66 are located such that the securing element 66 is in the first position of the lying part 18 according to Fig. 1 is in alignment with the two points on which one slider 48 rests on the counter slider 49 or on the bearing level 64, which is formed in one piece with the first stop 50.
  • the slider 48 lies in the second position of the lying part 18 Fig. 3 in alignment with the two points on which the slider 48 rests on the counter slider 49 or on the bearing level 64, which is formed in one piece with the second stop 52.
