Title: Furniture element

Description:
BACKGROUND AND SUMMARY OF THE INVENTION 
     Exemplary embodiments of the present invention relate to a furniture element, in particular a shelf or rack. 
     Furniture elements, such as shelves or racks in particular, in which a support plate and a shelf guided thereon and simultaneously movable in rotation and translation are arranged are known, for example, from JP 10318669 or DE 10 2017 106 170 A1. 
     In particular, the support plate described in the latter publication has proven itself in practice. 
     To move the shelf disclosed there, it is necessary to pull a side wall or a handle attached to it to rotate and advance the shelf. 
     Exemplary embodialents of the present invention are directed to further develop a furniture element, such as a shelf or a rack, in such a way that the operation of a movement of the shelf from an initial position to an unloading position or an opening movement of a rack dosed by side walls in the initial position to a position in which shelves of the rack are accessible by a user is further simplified. 
     The furniture element according to the invention, in particular in the form of a base or a rack having at least one layer level, has a carcass or a shelf and a bottom panel. 
     A base in this case means tray floors, turntables, and shelves in household appliances. 
     Support surfaces of the carcass and bottom panel facing one another each have at least one running groove in which rolling elements are guided. 
     The carcass can be moved relative to the bottom panel from an initial position to an intermediate position and further to an open position and back. 
     In the intermediate position, the carcass is rotated relative to the bottom panel in one direction of rotation and displaced in a predetermined direction. 
     A mechanism for opening and/or closing with a force accumulator supporting an opening and/or closing movement of the carcass is arranged on a surface of the bottom panel facing away from the carcass. 
     Such a furniture element is characterized by its easily actuatable opening, where only a small amount of pressure needs to be applied to the carcass of the furniture element to move the carcass from the initial position, supported by the force of the force accumulator, to the opening position. 
     According to an advantageous embodiment variant, the mechanism is arranged on a surface of the bottom panel facing away from the carcass. 
     In accordance with an advantageous further development of the invention, a guide channel is provided in the bottom panel that determines the direction, in which a guide element is displaceably mounted and the mechanism is coupled to the guide element.. 
     In addition, the force accumulator is fixed to the bottom panel and coupled with the guide element to support a sliding movement in the guide channel. 
     As a result, the entire mechanism of the mechanism is mounted under the bottom panel, invisible to the viewer. 
     In accordance with an advantageous further development, the mechanism comprises a pin projecting from the surface of the bottom panel remote from the carcass and a control disk rotatably mounted on the guide element and having a plurality of control elements for controlling movement of the control disk relative to the pin. 
     The pin and the control disk controlled by it ensure structurally simple, reliable control of the opening movement of the carcass of the furniture element. 
     In accordance with a further advantageous further development, the control disk is designed as an annular disk having a central opening surrounding the guide element.. The control elements are arranged, in particular formed, on an annular surface facing the bottom panel. 
     First control elements are preferably designed as circular catch elements spaced at equal angular distance from each other with a recess open towards the center of the control disk. 
     This makes it possible, in particular, to fix the carcass in the position as well as in a predetermined open position. 
     A second control element is preferably designed as a toothed ring arranged between the first control elements and the central opening with teeth arranged at equal angular distance from each other and directed towards the first control elements. 
     The teeth and an imaginary central perpendicular of the recesses of the first control elements are aligned in an angular range of 60 to 120°, particularly preferably approximately at right angles to each other. 
     This makes it possible to control the control disk in a simple manner in such a way that a decoupling of the control disk from the pin caused by pressing the carcass from the initial position against the opening direction is accompanied by a slight rotational movement of the control disk. 
     After subsequent release of the carcass, the opening movement of the carcass can take place, assisted by the force accumulator, with the pin passing between two adjacent first control elements, thus allowing the carcass to be moved further in the opening direction. 
     According to an advantageous embodiment variant of the invention, the force accumulator is designed as a torsion spring. 
     Such torsion springs can he manufactured inexpensively and mounted on the furniture element. 
     According to a preferred further development, the force accumulator, which is designed as a torsion spring, is fixed with a first end to a bore on the surface of the bottom panel facing away from the carcass. 
     This enables the force accumulator to be mounted on the bottom panel in a simple and cost-effective manner. 
     According to a further preferred further development, the force accumulator, which is designed as a torsion spring, is fixed with a second end in a bore in the surface of the guide element facing away from the carcass. 
     To avoid an undesirable increase in the height of the furniture element, the surface of the bottom panel facing away from the carcass has an indentation in which the mechanism is inserted. 
     According to a preferred embodiment variant, the guide element is part of a fixing device for vertically fixing the bottom panel to the carcass of the furniture element, which leads to a reduction in the necessary components of the furniture element. 
     According to a further alternative embodiment variant of the invention, a guide channel is provided in the bottom panel which determines the direction and in which a guide carriage is displaceably mounted. Such a guide carriage serves in particular to further stabilize and further improve the smooth running of such a rotatable furniture element. 
     The displaceable mounting of such a guide carriage in the guide channel of the bottom panel is also conceivable in principle without a mechanism for opening or closing the carcass with a force accumulator supporting an opening and/or closing movement of the carcass. 
     In an alternative embodiment variant, this mechanism for opening and/or closing the carcass with a force accumulator supporting an opening and/or closing movement of the carcass is designed as an ejector or push-to-move mechanism with a plunger coupled to the force accumulator, with which the guide carriage can be pushed away from a starting position along the guide channel. 
     The use of such a push-to-move mechanism makes it possible in particular to design the furniture element without an actuating handle and to initiate the opening movement of the furniture element by pushing it in against the intended opening direction. The use of a push-out mechanism that can be activated in another way is also conceivable. 
     According to a further preferred embodiment variant, the guide carriage is designed as part of a fixing device for vertical fixing of the bottom panel to the carcass. 
     According to a preferred further development, this fixing device has a roller bearing arranged on an underside of the guide carriage facing away from the carcass, having at least two rollers arranged one behind the other in the longitudinal direction of the guide channel. 
     The rollers have circumferential v-shaped grooves into which v-shaped webs project from opposite side walls of the guide channel, which v-shaped webs form running surfaces for the rollers. 
     The interaction of these rollers arranged one behind the other with the v-shaped webs ensures, on the one hand, reliable vertical securing of the guide carriage. 
     In addition, the support width of this translational-rotational mechanism is further increased by the multiple rollers arranged one behind the other, so that reliable guidance is ensured even when using heavier furniture elements, especially in a range of masses above 50 kg, without causing the furniture element to tip. 
     According to a further preferred embodiment variant, a bearing neck projecting into an opening in the support panel is integrally formed on an upper side of the guide carriage facing the carcass of the furniture element in order to rotate the support panel and thus the carcass of the furniture element relative to the bottom panel, and a roiling bearing ring inserted into the opening is fitted onto the bearing neck. 
     According to a further preferred embodiment variant, a stop is arranged on one end face of the guide carriage, which abuts against the plunger of the ejector or push-to-move mechanism when the guide carriage approaches. 
     Such an embodiment variant of the guide carriage allows a small number of components of the bearing.

     DETAILED DESCRIPTION 
     In the following figure description, terms such as top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the furniture element, the carcass, the bottom panel, the guide element, the pin, the control disk, the control element and the like selected in the respective figures. These terms are not to be understood restrictively, i.e., different working positions or the mirror-symmetrical design or the like can change these references. 
     In  FIGS. 1 to 4 , a first variant of a furniture element according to the invention is designated by the reference sign  1 . The furniture element  1  is designed here as a rack having a carcass  3  with a square base and three storage compartments with respective shelves  33  and two side walls  32  closing the carcass  3  laterally. 
     The furniture element  1  further has a bottom panel  2  arranged on the carcass  3 . 
     Support surfaces  21 ,  31  of the carcass  3  and of the bottom panel  2  facing one another have respective running grooves  22 ,  62  in which rolling elements  51  are guided, which serve to support the carcass  3  in a translationally and rotationally displaceabie manner relative to the bottom panel  2 . 
       FIG. 5  shows an alternative embodiment variant of a furniture element  1  according to the invention, wherein the carcass is designed here as a shelf having a support surface  31  which, in conjunction with a bottom panel  2  not visible here, can be moved in rotation and translation relative to the bottom panel  2  likewise in respective rolling elements guided in running grooves not shown here. 
     The operation of a corresponding furniture element is described, for example, in DE 10 2017 106 170 A or in DE 10 2018 108 977 A1. 
     This furniture element can also advantageously be equipped with a mechanism for opening and/or closing described below. 
     As shown in  FIG. 4 , it is also conceivable to form the running grooves  62  of the carcass  3  in a separate support panel  61  attached to the underside of a first shelf  31 . 
     As shown in  FIG. 4 , the roiling elements  51  are preferably mounted in a rolling element cage  5 , which in the embodiment variant shown here is designed as a square-shaped frame corresponding to the base area of the furniture element  1 , having a total of eight rolling elements  51  mounted therein, preferably designed as balls. 
     In this case, the bottom panel  2  together with the rolling elements  51 , the rolling element cage  5  and the support panel  61  or the running grooves  62 , if these are provided in the underside of the first shelf  31 , together form a translational-rotational bearing  6 . 
     With such a translational-rotational bearing  6 , the carcass  3  can be displaced relative to the bottom panel  2 , for example, out of a corner of the room  4  in a direction A and essentially simultaneously rotated by turning about a position-variable axis of rotation from the initial position shown in  FIG. 1  in a direction of rotation R 1  via an intermediate position shown in  FIG. 2  into an open position shown in  FIG. 3 . 
     The proportions of translation and rotation in the overall movement can vary over the course of the movement. 
     To enable the translational movement, the bottom panel  2  comprises a guide channel  23  that predetermines the direction A of the translation and in which a guide element  71  is displaceably mounted. 
     The guide element  71  is preferably part of a fixing device  7  for vertical fixing of the bottom panel  2  to the carcass  3  of the furniture element  1 . 
     In addition to the guide element  71 , which is held rotatably and displaceably in the guide channel  23 , the fixing device  7  has a screw  72  that is fixed in the underside of the lower shelf  31  and, in the case of the support panel  61  arranged between the bottom panel  2  and the carcass  3 , is screwed through a central opening  63  of this support panel  61  into a screw hole provided for this purpose in an upper side of the guide element  71  facing the carcass  3 . 
     The guide channel  23  extends approximately diagonally in the surface of the bottom panel  2 , thereby enabling the carcass  3  of the furniture element  1  to be moved out of a corner of the room  4 . 
     In this context, it is of course also possible to have an overall rotated arrangement of the translational-rotational bearing  6  with a guide channel  23  extending parallel to a side edge of the bottom panel  2 , for example, by means of which a carcass  3  of a furniture element  1  could be displaced forwards away from a rear wall, for example, perpendicularly to the rear wall, and simultaneously rotated. 
     As shown in  FIG. 6 , an opening and/or closing mechanism coupled to the guide element  71  is arranged on a surface of the bottom panel  2  facing away from the carcass  3 , with a force accumulator  9  supporting an opening and/or closing movement of the carcass  3 . 
     In the preferred embodiment variant shown here, the mechanism is designed as a so-called push-to-move mechanism with which, by pressing lightly against a front surface or side wall  32  of the carcass  3 , the mechanism is unlocked from a basic position shown in  FIG. 1  and, after subsequently releasing the carcass  3 , the furniture element  1 , driven by the force accumulator  9 , can be moved from the initial position shown in  FIG. 1  to the intermediate position shown in  FIG. 2 . 
     In addition to the force accumulator  9 , which is fixed to the bottom panel  2  and is preferably in the form of a torsion spring, the mechanism comprises a pin  10 , which projects from the surface of the bottom panel  2  facing away from the carcass  3 , and a control disk  8 , which is rotatably arranged on the guide element  71  and has a plurality of control elements  82 ,  83  for controlling the movement of the control disk  8  relative to the pin  10 . 
     In addition to the embodiment of the force accumulator  9  as a torsion spring, as shown in  FIGS. 6 to 20 , other embodiment variants of a force accumulator  9  are also conceivable. 
     The force accumulator  9  shown in  FIGS. 6 to 20 , which is designed as a torsion spring with a first leg  91  and a second leg  92  bent at an angle relative to the first leg  91 , is fixed, in particular inserted, with a first end  93 , which forms the end of the first leg  91 , in a bore  26  in the underside of the bottom panel  2  facing away from the carcass  3 . 
     A part of a first leg  91  of the torsion spring  9  directly adjoining this first end is thereby placed under a counter web  27  extending from a frame  25  of the bottom panel into an indentation  24  of the bottom panel in such a way that the first end  93  of the force accumulator cannot disengage from its position inserted into the bore  26 . 
     The counter web  27  is preferably designed thinner in the area of its free end  28  than the foot of this counter web  27 , which is dose to the frame  25 . 
     The indentation  24  serves to accommodate the mechanism, which is thus invisibly accommodated in the bottom panel  2  and protected from dirt. This results in a low overall height of the bottom panel  2 . 
     The force accumulator  9 , designed as a torsion spring, is fixed with a second end  94 . which forms the end of the second leg  92 , in a bore  73  in the surface of the guide element  71  facing away from the carcass  3 . 
     As shown in  FIGS. 6 to 20 , the control disk  8  is formed as a ring  81  with a central opening  84  encompassing the guide element  71 . 
     The control elements  82 ,  83  are arranged on an annular surface facing the bottom panel  2 , and in the preferred embodiment variant shown here are integrally formed on the latter. 
     First control elements  82  are designed as circular catch elements spaced at equal angular distance from each other with a recess  85  open towards the center of the control disk  8 , which is bounded by two legs of a respective first control element  82 . 
     An imaginary central perpendicular of the recess  85  is not aligned radially to the center of the opening  84 , but at an angle to it. 
     A second control element  83 , as shown in  FIGS. 6 to 20 , is designed as a toothed ring arranged between the first control element  82  and the central opening  84  with teeth  86  arranged at equal angular distance from each other and directed towards the first control elements  82 . 
     The teeth  86  and an imaginary central perpendicular of the recesses  85  of the first control elements  82  are preferably aligned in an angular range of 60 to 120°, in particular approximately perpendicular to each other. 
     It is also conceivable to attach feet (not shown) to the surface of the bottom panel  2  facing away from the carcass  3 , especially if the bottom panel does not have an indentation  24  shown in  FIG. 6  to accommodate the opening mechanism. 
       FIGS. 7 to 20  now describe an exemplary opening process of a furniture element  1  designed as a rack. 
     In this regard,  FIG. 7  shows an initial position of the carcass  3  of the furniture element  1  shown in  FIG. 1 . As shown here, the control disk  8  is positioned such that one of the first control elements  82  accommodates the pin  10  in its recess  85 . 
     By coupling the control disk  8  to the guide element  71 , a translational movement of the guide element  71  together with the carcass  3  in direction A, shown in  FIG. 2 , is thereby blocked. 
     In the position shown in  FIG. 8 , a user has pressed the carcass  3  slightly in the opposite direction to the direction A. The carcass  3  is then pressed in the opposite direction. 
     In this case, the guide element  71  is pressed together with the control disk  8  in a direction opposite to the direction A, so that the one first control element  82  is moved away from the pin  10 , so that in this position the pin  10  is positioned between the first control element  82  and the second control element  83  formed as a toothed ring, 
     When the carcass  3  is pressed further into the limit switching position, shown in  FIG. 9 , the second control element  83  is pressed into engagement with the pin  10  in such a way that the pin  10  is located between two teeth  86  of the second control element  83 . Further pressing of the carcass  3  is thus prevented. 
     The force accumulator  9 , which is designed as a torsion spring, is in its maximum tensioned position. 
     The user can then release the carcass  3 . As a result of this removal of pressure by the user, the force accumulator  9  in the form of a torsion spring acts and presses the guide element  71  together with the control disk  8  along the guide channel  23  in the direction A. This causes the carcass  3  to move into the intermediate position shown in  FIG. 2 . 
     In the process, a side edge of one of the first control elements  82  abuts against the pin  10 , causing a slight rotation of the control disk  8 . 
     The first control element  82  slides along the pin  10  during further movement with slight rotation of the control disk  8 , as shown it  FIGS. 10 and 11 . 
     After passing the first control element  82 , the pin  10  disengages from the mechanism, thereby releasing the carcass for translational-rotational movement to the intermediate position shown in  FIG. 2 . 
     The release position is shown in  FIG. 12 . 
       FIG. 13  shows the position of the bottom panel  2  in the it position of the carcass  3  shown in  FIG. 2 . The force accumulator  9 , which is designed as a torsion spring, is in its minimum tensioned position. 
     To fully open the carcass  3  from the intermediate position shown in  FIG. 2  to the open position shown it  FIG. 3 , the translational-rotational movement of the carcass  3  is first performed again until the pin  10  moves past the intermediate position shown in  FIG. 14 , in which the pin  10  is still out of engagement with the mechanism, to the position shown in  FIG. 15 . 
     In this process, an outer edge of one of the first control elements  82  abuts the pin  10 , causing the control disk  8  to rotate or align. 
     In the representation shown in  FIG. 16 , the carcass  3  and the control disk are in a position where the pin  10  can slide between two adjacent first control elements  82  in a direction opposite to the direction A. 
     In this position, the force accumulator  9  is unleaded, so that for the further movement of the carcass  3  into the open position, the user must again press against the carcass  3  against the direction A. 
     By pressing against the carcass  3  against the direction A, the pin  10  again gets between two teeth  86  of the second control element  83  when the control disk  8  is pushed further, as shown in  FIG. 17 . 
     The user feels this by the fact that no further movement of the carcass takes place when further pressure is applied, since this is blocked by the contact of the pin  10  with the second control element  83 . 
     If the user then releases the carcass, this removal of pressure in turn activates the force accumulator  9 , which presses the carcass  3  together with the guide element  71  and the control disk  8  in direction A, as shown in  FIG. 18 . 
     As shown in  FIG. 19 , the pin  10  thereby abuts the inner side of a leg of one of the first control elements  82  forming the recess  85 . 
     In this process, the control disk  8  is rotated until the pin  10  is fully engaged in the recess  85  of one of the first control elements  82 , as shown in  FIG. 20 , in this position, the carcass  3  is now completely in the open position, allowing easy access to the shelves  33 . 
     If the carcass  3  is to be transferred back to the closed position, the movement sequence described above runs in the same order. 
     Accordingly, to initiate the movement of the carcass  3  into the closed position, the carcass  3  is unlocked by pressing. 
     This ensures that the carcass  3  cannot leave the end positions without manual operation and is supported into the open or closed position during movement, 
     Alternatively, the mechanism could be designed to optionally have only one locking in one end position and only one support in the opening movement or in the closing movement, 
     With reference to  FIGS. 21 to 30 , an alternative embodiment variant for a translational-rotational mounting of a furniture. element  110  is described. 
     As shown in  FIGS. 21 and 22 , the bottom panel  120  also has running grooves  122  on its support surface  121  facing the support panel  161  for guiding rolling elements  151 , here in the form of balls. The running grooves  162  of the support panel  161  are not shown. 
     The rolling element  251  are also accommodated in s roiling element cage  150  for loss prevention. In contrast to the embodiment shown in  FIG. 4 , the rolling element cage  150  here is circular with several arms extending radially outward. 
     A guide channel  123  is also provided centrally and diagonally to two side edges of the bottom panel  120  which are aligned at right angles to each other. 
     A guide carriage  171  is displaceably mounted in this guide channel  123 . 
     The guide carriage  171 , as part of a fixing device  170 , has on its upper side facing the support panel  161  or the carcass  130  of the furniture element  110  a bearing neck  172  projecting into an opening  163  in the support panel  161 , which is preferably integrally formed on the upper skis of the guide carriage  171 . 
     This bearing neck  172  serves as an axis for a roiling bearing ring  177  inserted into the opening  163  of the support panel  161 , in particular a ball bearing ring, by means of which a simple rotational movement of the support panel  161  relative to the guide carriage  171  and thus relative to the bottom panel  120  is made possible. 
     On the underside of the guide carriage  171  facing away from the support panel  161 , there is a roller bearing having at least two rollers  174  arranged, in particular fixed, one behind the other in the longitudinal direction of the guide channel  123 . 
     Each of these rollers  174  has a circumferential v-shaped groove  175  into which protrude from opposite side wails of the guide channel  123  v-shaped webs  124  forming running surfaces for the rollers  174 . 
     The v-shaped grooves  175  of the rollers  174 , which are guided along the v-shaped webs  124  in the guide channel  123 , result in an extremely stable and constant sequence of the translational-rotational movement of the furniture element  110 . The fixing device  170  is secured against unintentional loosening at the top and bottom in each case by a fixing element, in particular a detachable fixing pin  176 ,  178 . This makes it possible to assemble and disassemble the furniture element in a simple manner. 
     In this embodiment variant, the translational-rotational mounting is also preferably configured such that the guide carriage  171 , analogous to the guide element  71 , moves from an initial position in which the furniture carcass  130  is in an initial position relative to the stationary portion of the furniture item  100 , during an opening movement, moves along the guide channel  123  to opposite ends of the guide channel  123 , and moves from the opposite end of the guide channel  123  back to the initial position to reach an open position, 
     As shown in  FIGS. 21 and 25 to 27 , as an alternative to the mechanism shown in  FIGS. 6 to 40  for opening and/or closing the carcass  3  with a force accumulator  9  assisting an opening and/or closing movement of the carcass  3 , an ejector or push-to-move mechanism  140  with a plunger  142  coupled to a force accumulator  141  is used in the bottom panel  120 . 
     With this ejector or push-to-move mechanism  140 , the guide carriage  171  can be pushed away from an initial position or an open position along the guide channel  123  after activation thereof, thereby initiating the translational-rotational movement of the support panel  161  and thus of the furniture element  110 . 
     As shown in  FIGS. 25-27 , the ejector or push-to-move mechanism  140  is accommodated on an underside of the bottom panel  120 , facing away from the support panel  161 , in a receiving groove  127  provided for this purpose, which here is fixed in its position in the receiving groove  127  by a retaining element  143  formed as a plate. 
     The plunger  142  thereby protrudes into the guide channel  123 , as shown in  FIGS. 26 and 27 . 
     As a result, by approaching the guide carriage  171 , the plunger  142  can be pressed against the force of the force accumulator  141 , for example in the form of a compression spring, into a housing accommodating the force accumulator  141  and pressed into a latching position via a latching mechanism known from the prior art. 
     To activate the push-to-move mechanism  140 , the plunger  142  must be pushed further into the housing from the position shown in  FIG. 5  against an ejection direction, which is carried out by pressing against the carcass of the furniture element  110  against the ejection direction of the push-to-move mechanism  140 . 
     When the push-to-move mechanism  140  is triggered, the guide carriage  171  is pushed away along the guide channel  123 , thus causing the carcass  130  of the furniture element  110  to open. 
     In this case, the plunger  142  interacts with the guide carriage  171  in such a way that not only an opening movement of the carcass  130  of the furniture element  110  from an initial position, but also a closing movement of the carcass  130  of the furniture element  110  is supported, i.e., both directions of movement are supported with only one ejector or push-to-move mechanism  140 . 
     Such an initial position is shown by way of example in  FIG. 28 . In this position, the carcass  130  of the furniture element  110  is positioned in the furniture item  100  in such a way that outer walls of the carcass  130  together with outer wails of the fixed part of the furniture item  100  close the furniture element to the outside. 
     In the open position shown as by way of example in  FIG. 30 , the carcass  130  of the furniture element  110  is positioned in the furniture item  100  in such a way that the two outer walls of the carcass  130  are positioned directly in front of the outer walls of the stationary part of the furniture item  100  and are not accessible from the outside by areas of the furniture element closed by external walls. 
     In both the initial position shown in  FIG. 28  and the open position shown in  FIG. 30 , the guide carriage  171  is in the position shown in  FIG. 25 , as explained above. 
     According to a further preferred embodiment variant, a stop  173  is arranged on one end face of the guide carriage  171  to repel the guide carriage  171 . When the guide carriage  171  approaches the plunger  142  of the ejector or push-to-move mechanism  140 , the stop  173  abuts the plunger  142 . 
     To illustrate the movement of the furniture element  110 ,  FIGS. 23 and 24  show a bottom panel  120  resting on a base  101  of a piece of furniture, on which the support panel  161 , which is attached to the underside of the furniture carcass  130  of the furniture element  110 , is mounted so as to be movable in translation and rotation. Here,  FIG. 23  shows the it position corresponding to a positioning of furniture elements  110  in the initial position shown in  FIG. 28 . 
       FIG. 24  shows a rotated position of the support panel  161  by approximately 65° relative to the base  101  and the bottom panel  120 . 
       FIG. 25  shows the initial position shown in  FIG. 23  from the underside of the bottom panel  120  and the support panel  161 , in which the guide carriage  171  almost completely presses in the plunger  142  of the ejector or push-to-move mechanism  140 . 
       FIG. 26  shows a 5° rotated position of the support panel  161  relative to the bottom panel  120  from the perspective corresponding to  FIG. 25 . In this position, the support panel  161  is translationally displaced by the distance of movement of the plunger  142  from the initial position. 
       FIG. 27  shows the open position of the support panel  161  relative to the bottom panel  120 , which from a vertical view corresponds to the position of the furniture elements  110  in a furniture item of the representation according to  FIG. 30 , in which the furniture element  110  or the support panel  161  have been rotated by 180°. 
     The position of the furniture elements  110  with furniture carcass  130  according to the position shown in  FIG. 29  corresponds to the representation of the support panel  161  relative to the bottom panel  120  and the base  101  in the position shown in  FIG. 24 .
