Lounger with swiveling reclining section

Description

[0001] The present invention relates to a reclining piece of furniture with a reclining section that can be pivoted in a horizontal plane between a first position and a second position relative to the support frame of the reclining piece on which the reclining section is mounted. The reclining piece of furniture thus offers two different configurations, allowing the reclining section to be oriented differently as needed. Such a generic reclining piece of furniture is essentially derived from DE 299 19 083 U1.

[0002] Further details of the state of the art can also be found in documents CN 103 892 610 B and DE 44 33 802 A1.

[0003] If, for example, the reclining furniture is part of a larger sofa seating group, where the reclining part of the reclining furniture borders a seat of an adjacent seating unit of the sofa seating group, the difficulty may arise that the side of the reclining part that borders the adjacent seat collides with it when the reclining part is swiveled between the first position and the second position.

[0004] The invention is therefore based on the objective of providing a reclining piece of furniture of the type mentioned at the outset, the reclining part of which can be pivoted without collision, for example when the reclining piece of furniture is part of a larger sofa seating group.

[0005] This problem is solved with a reclining furniture having the features of claim 1.

[0006] A cam guide with two non-parallel guide rails is effectively coupled between the lying surface and the support frame, in each of which a guide element such as a slider or a roller is guided, wherein either the guide rails are attached to the support frame and the guide elements to the lying surface or the guide rails to the lying surface and the guide elements to the support frame.

[0007] Because the guide elements are guided in the two non-parallel guide rails, the lying surface does not pivot around a fixed axis when swiveled, which would otherwise lead to the collision problem described earlier. Instead, because the guide elements are guided in the two non-parallel guide rails, the lying surface rotates around a fictitious axis when it is swiveled between the first and second positions. The position of this fictitious axis changes as the lying surface is swiveled. Thus, depending on the swivel position, the lying surface essentially rotates around a different axis.With a suitable shape, position and alignment of the two guide rails, the fictitious axis of rotation of the reclining section can shift in such a way that the side of the reclining section which borders an adjacent seat section of a larger sofa seating group is pivoted when the reclining section is swivelled in such a way that there is no collision with the adjacent seat section.

[0008] Preferably, the two guide rails are arranged and aligned with each other such that, viewed from above, at least one corner of the reclining section is always located on or within the outline of the support frame, both in the first and second positions of the reclining section and in any pivot positions between the first and second positions. Since at least one corner of the reclining section always remains on or within the outline of the support frame, it cannot undesirably collide with any adjacent seating sections or other components of a larger sofa seating group.

[0009] According to a preferred embodiment, the shape, position, and orientation of one of the two guide rails, viewed from above, can correspond to the path of one of the two guide elements between the first and second positions. Similarly, the shape, position, and orientation of the other of the two guide rails, viewed from above, can correspond to the path of the other of the two guide elements between the first and second positions. To determine the shape, position, and orientation of the two guide rails, one can, for example, first mount two spaced-apart guide elements on the underside of the lying surface. The lying surface can then be moved above the support frame into a position corresponding to the first position of the lying surface.In this state, no guide rails are yet provided on the support frame.

[0010] If the lying section is now manually pivoted from this first position into its second position, for example by 90°, such that at least one corner of the lying section, viewed from above, is always on or within the outline of the support frame, then the two guide elements each describe a path with a specific shape, position, and orientation. If guide rails shaped according to the shapes of the two paths are then attached to the support frame, such that their position and orientation correspond to the respective position and orientation of the respective path, the lying section can subsequently be coupled to the support frame by inserting the guide elements into the respective guide rail.If the lying section is now pivoted on the support frame between its first and second positions, at least one corner of the lying section will necessarily always remain on or within the outline of the support frame in the desired manner, since the two guide rails correspond to the trajectories of the two guide elements in terms of shape, position and orientation, so that at least one corner always remains on or within the outline of the support frame.

[0011] According to a preferred embodiment, one of the two guide rails can run parallel to a short side of the support frame or lying surface, and the other guide rail runs parallel to a long side of the support frame or lying surface, and thus perpendicular to the guide rail running parallel to the short side of the support frame or lying surface. In this case, the two guide rails can advantageously be designed as straight guide rails. However, depending on the position of the two guide elements, they may also describe curved paths, which means that the two guide rails must be designed and arranged according to such curved paths.

[0012] According to a further embodiment, the reclining section may have a head end and a foot end, with the guide rail located closer to the head end than to the foot end. In the first position, the foot end of the reclining section, viewed from above, is on or within the outline of the support frame, whereas in the second position, rotated by 90°, the foot end of the reclining section, viewed from above, is located outside the outline of the support frame. Thus, in the first position, the reclining section can be located entirely above the support frame, whereas in the second position, the foot end of the reclining section cantilevers over the support frame, so that the foot end is, in effect, "in the air".

[0013] To prevent unwanted frictional wear between the lying surface and the support frame due to the pivoting of the lying surface, a further embodiment provides that the lying surface has a glider with a sliding surface on its underside and the support frame has a counter-glider with a counter-sliding surface on its upper side, on which the sliding surface of the glider rests in the first and second positions of the lying surface as well as in any pivoting positions in between. The glider and the counter-glider can, for example, be coated with a material with a low coefficient of friction as the sliding surface and counter-sliding surface, respectively, in order to minimize friction between the glider and the counter-glider and thus reduce wear.

[0014] While both the first and second positions can be defined by the ends of the two guide rails, to prevent overloading the guide elements within the rails when reaching their ends, the reclining furniture can also have a first and a second fixed stop. In the first position, the glider of the reclining section rests against the first stop, and in the second position, against the second stop. Because the glider rests against the respective stop, the reclining section cannot be pivoted beyond the respective position (first or second position), which could otherwise lead to overloading of the guide elements.

[0015] According to a further embodiment, the reclining furniture may also have a first and a second fixed ramp, wherein the sliding surface of the glider of the reclining section runs onto the first ramp before or upon reaching the first position and onto the second ramp before or upon reaching the second position. Thus, if, for example, the reclining surface is pivoted by an operator from its first position to its second position, the sliding surface does not immediately collide with the second stop; rather, the operator receives haptic feedback due to the glider running onto the second ramp, which indicates to the operator that the second stop or the second position is about to be reached.The operator thus knows that the second position will soon be reached and can therefore reduce the force required to swivel the lying section accordingly, so that the glider does not hit the second stop with force, which could otherwise lead to damage to the glider and / or the respective stop.

[0016] Although the stops and the ramp can be designed as separate components, according to a preferred embodiment it can be provided that the first stop is formed integrally with the first ramp and the second stop is formed integrally with the second ramp.

[0017] To enable the lying surface to be pivoted with minimal effort, a further embodiment provides that each guide element comprises a roller, the respective roller being arranged in and guided by an associated guide rail. Additionally, each of the two guide rails can form a guide channel and a slot through which the respective guide element, with its roller leading, extends into the guide channel, the clear width of which is smaller than the diameter of the respective roller. Because the clear width of the slot is smaller than the diameter of the respective roller, the roller is held securely in the guide rail or guide channel.The roller guidance of the guide elements thus not only reduces the friction between the guide elements and the respective guide rails; rather, the lying surface is also secured against lifting forces due to the fact that the rollers are guided in the respective guide rail in a way that prevents them from falling out, so that the lying surface cannot tip over, especially in its second position.

[0018] While the guide rails, stops, and ramps can be attached to the support frame using suitable fasteners such as crossbeams, trusses, or support arms, a preferred embodiment provides that the guide rails, counter-glider, two stops, and / or two ramps are attached to the upper surface of the rectangular plate of the support frame, which forms the rectangular outline of the support frame. According to the invention, this plate not only serves to mount the components to the support frame but also functions as a kind of table or shelf in the second position of the lying surface, since in this position the plate is not completely covered by the lying surface.

[0019] Although the lying surface can be secured against lifting forces by the rollers guided in the guide rails, as explained above, the foot end of the lying section can still be lifted without further measures. Therefore, an arc-shaped slot can be formed in the plate through which a locking element attached to the underside of the lying section extends. At its free end, below the plate, this locking element can have a locking component with a larger cross-sectional dimension than the arc-shaped slot, thus preventing the locking element and, consequently, the lying section from being lifted.Since the locking element in question also describes a specific trajectory curve when the lying part is pivoted between its first and second positions, the arc-shaped slot has a shape that describes the locking element when pivoting between the first and second positions.

[0020] The invention will now be described in the following purely exemplary manner with reference to the figures in which: Fig. 1 shows an embodiment of a reclining furniture according to the invention in a backlit top view, wherein the reclining part is in a first position; Fig. 2 shows the reclining furniture in the position of Fig. 1 in perspective view; Fig. 3 shows the chaise longue of the Fig. 1 shown in a backlit top view, with the reclining section in a second position rotated 90° relative to the first position; Fig. 4 shows the reclining furniture in the position of Fig. 3in perspective view; Fig. 5 shows a cross-sectional view of the two guide rails; and Fig. 6 shows a view of the two stops with the ramp formed integrally with them.

[0021] As the synthesis of Figures 1 to 4As can be seen from the illustration, the reclining furniture 10 according to the invention has a substantially rectangular support frame 12, which is supported at the foot end by supports 14 on the floor and at the head end by hooks 16 on an adjacent seat section (not shown) of a larger sofa seating group to which the reclining furniture 10 belongs. The support frame 12 in turn supports a substantially rectangular reclining section 18 with two short sides 20 and two long sides, which comprises a slatted frame 28 and a cushion 26 resting on it. The slats of the slatted frame 28 are not shown here for clarity, but the slat holders 30 are. In addition, the reclining furniture 10 according to the invention includes a back section or backrest 24, the inclination of which can be adjusted.

[0022] As in particular the overview of the Figures 2 and 4The lying section 18, which can be removed, is pivotably mounted on the support frame 12 by means of a complex cam track 35, which allows the lying section 18 to be moved in a horizontal plane with respect to the support frame 12 between a first position according to the Figure 1 and 2 and a second position according to the Figures 3 and 4to pivot by 90°. The cam guide 35, which will be explained in more detail below, is located closer to the head end 32 than to the foot end 34. In the first position, the foot end 34 of the reclining section 18 is on or within the outline of the rectangular support frame 12, whereas in the second position it is outside the outline of the support frame 12. This is because the cam guide 35 is located closer to the head end 32 than to the foot end 34 of the reclining section 18, allowing the foot end 34 to pivot from the first position into the second position of the reclining section 18, in which the reclining section 18 is freely cantilevered from the support frame 12.

[0023] If the reclining section 18 were mounted on a fixed pivot axis on the support frame 12, contrary to the present invention, the problem would arise that when the reclining section 18 is pivoted, the front corner 22 at the head end 32 of the reclining section 18, which borders an adjacent seating unit, would collide with it. To avoid this, the guide 35 is designed such that the corner 22 of the reclining section 18 is always located on or within the outline of the support frame 12 when it is pivoted.

[0024] The following will now focus in particular on the Figure 1 and 3A possible embodiment of the cam guide 35 is explained. In the embodiment shown here, the cam guide 35 comprises 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.

[0025] Furthermore, the guide track 35 comprises two guide elements 40, 42 attached to the underside of the lying section 18, which are slidably guided in the first and second guide rails 36, 38, respectively. Contrary to the described embodiment, it is also possible to attach the two guide rails 36, 38 to the underside of the lying section 18 and the two guide elements 40, 42 to the top of the plate 13 of the support frame 12.

[0026] If we now consider, for example, the backlit top view of the Fig. 1 , it can be seen that in the first position of the lying part 18 shown, the first guide element 40 is located at the end of the first guide rail 36, which in the top view of the Fig. 1 is located near corner 22. The second guide element 42, on the other hand, is located at the end of the second guide rail 38 that adjoins the first guide rail 36. If the lying part 18 is now moved from the position in the Fig. 1 the first position shown, clockwise in the direction of its in the Fig. 3 When the second position is pivoted as shown, 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 effect that the front corner 22 of the lying section 18 does not collide with an adjacent seat section (not shown) when the lying section 18 is pivoted. Due to the described arrangement of the two guide rails 36, 38, the front corner 22 of the lying section 18 moves along the short side 20 of the support frame 12 during the pivoting of the lying section 18, so that no collision with an adjacent seat section can occur.

[0027] Contrary to the embodiment shown here, in which the two guide rails 36, 38 are straight and perpendicular to each other, the guide rails can also have any shape, position, and orientation. The shape, position, and orientation of the guide rails 36, 38 must be selected such that, given a specific position of the guide elements 40, 42 on the underside of the lying part 18, they correspond to the path of the respective guide element 40, 42 when the lying part 18 is pivoted from its first to its second position.

[0028] To determine the shape, position, and orientation of the two guide rails 36, 38, one can proceed, for example, by first mounting two spaced-apart guide elements 40, 42 on the underside of the lying section 18. The lying section 18 can then be positioned above the support frame 12 in a position corresponding to its first position. If, starting from this first position, the lying section 18 is then pivoted into its second position, for example by 90°, such that corner 22, viewed from above, moves along the short side of the support frame, the two guide elements 40, 42 each describe a path with a specific shape, position, and orientation.If guide rails 36, 38, shaped according to the forms of the two trajectories, are attached to the top of the plate 13 of the support frame 12, such that their position and orientation correspond to the respective position and orientation of the respective trajectory, the lying section 18 can then be coupled to the support frame 12 by inserting the guide elements 40, 42 into the respective guide rails 36, 38. If the lying section 18 is now pivoted on the support frame 12 between its first and second positions, the corner 22 of the lying section 18 is necessarily always kept on the short side of the support frame 12, since the two guide rails 36, 38 correspond in shape, position, and orientation to the previously determined trajectories of the two guide elements 40, 42, so that the corner 22 moves along the short side of the support frame 12.

[0029] Although the previously described cam track 35 guides the pivoting movement of the lying section 18 in the desired manner, ensuring that the front corner 22 of the lying section 18 always remains on or within the outline of the support frame 12, two rod-shaped gliders 48 are attached to the underside of the lying section 18, and in particular its slatted base 28, to prevent the lying section 18, and especially its slatted base 28, from scratching the support frame 12 and especially its plate 13, during pivoting. The sliding surfaces of these gliders rest on the counter-sliding surface of a counter-glider 49, which is attached to the top of the plate 13 of the support frame 12. The two gliders 48 and the counter-glider 49 are aligned with each other such that the counter-glider 49 rests on the counter-glider 48 in both the first and second positions.

[0030] So that the reclining section 18, especially in the second position, according to the Figures 3 and 4To prevent tipping, 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. At the free end of the respective guide element 40, 42, a roller 44, 46 is provided 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 thus held securely in the respective guide rail 36, 38 and, in particular, cannot be pulled out upwards, in order to prevent the lying part 18 from tipping in the second position according to the Figures 3 and 4 can tip over.

[0031] To prevent the lying section 18 from pivoting beyond the first or second position, two stops 50, 52 are attached to the plate 13 of the support frame 12. A slider 48 of the lying section 18 rests against these stops in the first or second position of the lying section 18. In the embodiment shown here, the two stops 50, 52 are each formed integrally with a respective ramp 54, 56, on which the sliding surface of the slider 48 runs shortly before reaching the first or second position.

[0032] The two ramps 54, 56 provide an operator pivoting the lying section 18 not only with haptic feedback indicating that the first or second position of the lying section 18 is about to be reached; rather, the respective glider 48 rests in the first or second position on a bearing plane 64, which extends between the respective stop 50, 52 and the respective ramp 54, 56, see the Fig. 6In the first position, the lying section 18 rests with a glider 48 on both the counter-glider 49 and the bearing surface 66, which is integrally formed with the first stop 50. Similarly, in the second position, the lying section 18 rests with its glider 48 on both the counter-glider 49 and the bearing surface 64, which is integrally formed with the second stop 52. Since the foot end 34 of the lying section 18 is not supported in either the first or the second position, the opposite head end 32 experiences a lifting load. However, this load is transferred as tensile forces via the two guide elements 40, 42 and the rollers 44, 46 provided thereon into the two guide rails 36, 38 and from there to the support frame 12, so that the lying section 18 cannot tip over in either the first or the second position.

[0033] To secure the lying section 18 against lifting loads acting on the foot end 34 of the lying section 18 in either the first or second position, an arcuate slot 62 is further formed in the plate 38. A locking element 66 extends through this slot and is attached to the underside of the lying section 18. The arcuate slot 62 describes the same path as the locking element 66 when the lying section 18 pivots between the first and second positions. The arcuate slot 62 and the locking element 66 are positioned such that the locking element 66, in the first position of the lying section 18, according to Fig. 1 in line with the two points on which one slider 48 rests on the counter-slider 49 or on the bearing surface 64, which is formed integrally with the first stop 50. The slider 48 lies in the second position of the support section 18 in a corresponding manner. Fig. 3in line with the two points on which the glider 48 rests on the counter-glider 49 or on the bearing plane 64, which is formed in one piece with the second stop 52. Reference symbol list
