Pull-out device for a cabinet, especially a corner cabinet

Description

[0001] The present invention relates to a pull-out device for a cabinet, in particular a corner cabinet. Pull-out devices for cabinets, in particular corner cabinets, are used to make the storage space of a cabinet, especially the storage space located in the corner of a corner cabinet, more accessible.

[0002] Pull-out devices for cabinets or corner cabinets with corresponding pull-outs are known from the state of the art.

[0003] EP 1 616 503 A2 shows a corner cabinet with an off-center opening and a one-piece shelf supported by two guide rods that can be moved almost completely out of the interior of the corner cabinet. The movement controlled by the two guide rods defines the outer contour of the one-piece shelf to maximize the shelf area. In this process, parts of the interior of the corner cabinet remain unused.

[0004] WO 2020 / 079643 A1 discloses a pull-out device for a corner cabinet with an off-center opening. The pull-out device comprises two receiving elements that can be arranged side by side in the corner cabinet. The two receiving elements are connected via a drive mechanism comprising a system of guides and pivoting levers. When the first receiving element is pulled out in a first pull-out direction, the second pull-out element is automatically pulled out in a second pull-out direction perpendicular to the first pull-out direction and then moved along the first pull-out direction. The interior space of the corner cabinet is utilized effectively, but the pull-out device has a mechanically complex design.

[0005] EP 3 804 564 A1 discloses a pull-out device for a corner cabinet with a first and a second storage element that can be arranged side by side in the corner cabinet. The first storage element can be moved out of the corner cabinet with a translational movement. The two storage elements are pivotally connected to each other, with the rotational movement being controlled by a control device. The second storage element is rotated 180 degrees during movement. The control device must control a complex movement of the second storage element. Furthermore, parts of the interior of the corner cabinet remain unused.

[0006] Another pull-out device is known from US 2022 / 211174 A1.

[0007] The object of the present invention is to provide a pull-out device for a cupboard, in particular a corner cupboard, as well as a corner cupboard with such a pull-out device, which are constructed in a simple, cost-effective and robust manner and which enable the largest possible shelf area, which makes the best possible use of the interior space of a cupboard, in particular a corner cupboard.

[0008] This object is achieved by a pull-out device for a cupboard, in particular a corner cupboard, having the features of claim 1 and by a corner cupboard with such a pull-out device according to claim 15.

[0009] The pull-out device for a cabinet according to the invention comprises a multi-part shelf that can be moved between a storage position and an extended position. The multi-part shelf has a first shelf section and at least one second shelf section. The pull-out device has a first guide device supporting the first shelf section and a second guide device supporting the second shelf section. The pull-out device further has a coupling device. This is attached to the first shelf section so as to be pivotable about a coupling pivot axis and movably connects the first and second shelf sections to one another.The second shelf section is fixed to the second guide device so as to be pivotable about a pivot axis, and the second guide device is designed to guide the second shelf section in a trajectory curve in the shape of a circular arc during the displacement between the storage position and the extension position.

[0010] The second guide device, which guides the second shelf section along a circular arc-shaped trajectory from the storage position to the extended position, with the second shelf section being pivotably mounted on the second guide device about a pivot axis, allows the extension device according to the invention to be constructed using simple means. At the same time, it enables a design of the first shelf section and the second shelf section that significantly increases the total available shelf area and improves the utilization of the available interior space of a cabinet.

[0011] Preferably, the first guide device and the second guide device each support the first shelf section and the second shelf section on their undersides. This makes the entire shelf surface available for accommodating objects.

[0012] For support from below, it is sufficient if the part of the first and / or second guide device that is directly connected to the first shelf section or the second shelf section, respectively, is arranged on the underside of the respective shelf section. Additional parts or elements of the respective guide devices can also be arranged next to or above the respective shelf section.

[0013] Preferably, in a pull-out device designed for use in a corner cabinet, the first shelf section is designed for storage in a storage area of ​​the corner cabinet, and the second shelf section is designed for storage in a corner area of ​​the corner cabinet adjacent to the storage area. The interior space available in a corner cabinet can be utilized particularly effectively with a pull-out device designed in this way.

[0014] The second guide device preferably has a pivot arm that can be secured to a cabinet so as to be pivotable about a pivot arm pivot axis. By using such a pivot arm as the second guide device, the circular arc-shaped trajectory can be implemented particularly easily. Such a pivot arm can be secured in particular to one of the side walls of a cabinet. The pull-out device can thus also be installed above other built-in components in a cabinet. The pivot arm can alternatively or additionally be secured to the floor of a cabinet. For example, the pivot arm pivot axis can be implemented by a support column of a cabinet, in particular a corner cabinet. The pivot axis, the coupling pivot axis, and the pivot arm pivot axis are aligned parallel to one another and vertically. The pull-out device has a simple design.

[0015] The pivot arm is particularly preferably angled. An angled pivot arm enables the second shelf section to be easily moved along a circular arc-shaped trajectory, in which the pivot arm is arranged, in particular, to encompass a corner cabinet post. This allows the radius of movement or the length of the circular arc-shaped trajectory to be extended.

[0016] More preferably, the pivot arm is arranged above the first guide device. This means that the plane in which the pivot arm is arranged lies above the plane in which the first guide device is arranged. Because the first and second guide devices are arranged on different planes at least in part - at least in the region of the pivot arm of the second guide device - the arrangement of the first and / or the second guide device in the respective plane can be freely selected. In particular, the two guide devices can be arranged such that, viewed from above onto the pull-out device, they cross when the pull-out device is moved from the storage position to the extended position. Due to the arrangement on different planes, a collision of the guide devices does not occur despite such a crossing.

[0017] Furthermore, the pivot arm of the second guide device is particularly preferably angled and, in the storage position of the pull-out device and in a top view of the pull-out device, is arranged to partially encompass the second shelf section. Such an arrangement of the pivot arm ensures that the pivot arm does not sweep over the surface above the second shelf section during movement, even if it is arranged in a plane above it. This prevents a collision of the pivot arm with objects arranged on the second shelf section. In particular, a pivot arm configured in this way can also be arranged in the same plane as the second shelf section.This creates a pull-out device that is particularly compact in height, but which nevertheless allows the first and second guide devices to be arranged at least partially in different planes and thus allows the guide devices to cross each other in plan view when the pull-out device is moved.

[0018] Preferably, the coupling pivot axis is arranged in the central quadrant of a 3x3 matrix that is optimally adapted to the shape of the first shelf section. The 3x3 matrix covers the surface of the first shelf section in a top view with nine equally sized and equally shaped rectangles, preferably squares. The dimensions of the rectangles are adjusted to optimally cover the surface of the first shelf section. The coupling pivot axis is thus arranged in a central area of ​​the first shelf section.

[0019] Advantageously, the distance between the coupling pivot axis and one of the lateral contour lines of the first shelf section is 40% to 60%, preferably 45% to 55%, and particularly preferably 50% of the width of the first shelf section. The width is the shortest distance between the opposing lateral contour lines of the first shelf section through the coupling pivot axis.

[0020] Due to the circular arc-shaped trajectory of the second guide device, the coupling device and the arrangement of the second shelf section on the second guide device so that it can pivot about the pivot axis, the second shelf section is arranged behind the first shelf section in the extended position. The arrangement of the coupling pivot axis in a central region of the first shelf section means that the second shelf section is also arranged approximately centrally behind the first shelf section in the extended position. This allows the space available in a cabinet to be used particularly well. The total shelf area of ​​the pull-out device can thus be maximized. A corresponding arrangement of the first and second shelf sections approximately centrally one behind the other in the extended position also results in an attractive appearance of the pull-out device in the extended position.

[0021] Preferably, the first shelf section is mirror-symmetrical. A symmetrical design of the first shelf section results in an attractive appearance of the pull-out device in the extended position.

[0022] The distance of the coupling pivot axis from a rear contour line of the first shelf section is preferably 90% to 120%, preferably 100% to 110%, of the distance of the coupling pivot axis from the lateral contour line of the first shelf section which is adjacent to the second shelf section in the storage position. In the present arrangement, the orientation of the coupling pivot axis with respect to the depth of the first shelf section determines the possible width of the second shelf section, wherein the width designates the distance between the lateral contour lines of a shelf section in the pull-out position and the depth designates the distance between the front and rear contour lines of a shelf section in the pull-out position. In particular with typical rectangular corner cabinets with corner cabinet dimensions of in particular 60 cm × 120 cm, the space available in the interior of the corner cabinet can be particularly well utilized and the total shelf area can be maximized.In addition, this arrangement allows the distance between the first shelf section and the second shelf section in the extended position to be made particularly small, which gives the pull-out device a high-quality appearance in the extended position.

[0023] Preferably, the coupling device is arranged on the underside of the first and second shelf sections. This prevents the space available on the shelf sections for arranging objects from being compromised by the coupling device.

[0024] Preferably, the second shelf section is rigidly connected to the coupling device. The movements of the first and second shelf sections of a multi-part, in particular two-part, shelf during relocation are determined thereby. The pull-out device installed in a cabinet has precisely the degrees of freedom required for relocation between the storage position and the extended position. The pull-out device is easy to operate. The rigid connection between the coupling device and the second shelf section allows for a simple and robustly constructed pull-out device. The coupling device acts like a drawbar, with which the second shelf section is connected to the first shelf section. The second shelf section follows the first shelf section like a trailer.

[0025] Preferably, the trajectory of the second guide device in the form of a circular arc has an angle of 100° to 140°, preferably 110° to 130°, particularly preferably 125°. In an alternative preferred embodiment, the trajectory of the second guide device in the form of a circular arc has an angle of 100° to 150°, preferably 120° to 140°, particularly preferably 133°. A trajectory in the form of a circular arc with the specified angles enables not only the displacement of the second shelf section but also a partial displacement of the second shelf section out of the interior of the cabinet. In the extended position, the second shelf section can be arranged so that it partially protrudes beyond the plane of an opening, such as a door opening of the cabinet, from the interior. This improves accessibility to the second shelf section.

[0026] Preferably, the pivot axis is arranged in the middle quadrant of a 3x3 matrix optimized for the shape of the second shelf section. The 3x3 matrix covers the surface of the second shelf section in a top view with 9 equally sized and equally shaped rectangles, preferably squares. The dimensions of the rectangles are adjusted to optimally cover the surface of the second shelf section. The pivot axis is thus arranged in a central region of the second shelf section. Such an arrangement enables the design of the second and first shelf sections in such a way that the total shelf area is as large as possible, thus ensuring particularly good utilization of the space available in the interior of a cabinet.

[0027] The pivot axis is preferably arranged in a region around the center of gravity of the second shelf section. The arrangement in a region around the center of gravity of the second shelf section means that the distance of the pivot axis from the center of gravity of the second shelf section is at most half, preferably at most one-third, particularly preferably at most one-fifth of the distance of the center of gravity from the outer contour of the second shelf section, measured by the pivot axis. Firstly, with this arrangement, the second guide device centrally absorbs the forces acting on the second shelf section by objects arranged on the second shelf section. The load on the second shelf section due to tilting moments can thereby be reduced.On the other hand, this arrangement enables the second and first shelf sections to be designed in such a way that the total shelf area is as large as possible and thus a particularly good use of the space available in the interior of a cabinet is achieved.

[0028] In an alternative, preferred embodiment, the pivot axis is arranged outside the outer contour of the second shelf section when viewed from above. This is particularly advantageous when using a second guide device with an angled pivot arm that partially encompasses the second shelf section when the pull-out device is in its storage position and when viewed from above. By arranging the pivot axis outside the outer contour of the second shelf section, the pivot arm can be easily arranged in the same plane as the second shelf section.

[0029] Preferably, the first guide device is designed to guide the first shelf section in a purely linear movement. This enables a particularly simple design of the pull-out device. For example, the pull-out device can be used in a drawer-like installation situation. In this case, the first shelf section can be provided with a corresponding panel on its front side and form a drawer. However, the pull-out device can also be arranged behind a cabinet door of a cabinet, which is typically independent of the pull-out device.

[0030] Particularly preferably, the first guide device is designed as a pull-out guide. A pull-out guide enables a purely linear, translational displacement of the first shelf section from the interior of a cabinet into an area in front of the cabinet. Further particularly preferably, the pull-out guide comprises at least one multi-part telescopic rail. This makes it easy to move the first shelf section completely out of the interior of a cabinet. The pull-out guide can also comprise more than one telescopic rail, in particular two telescopic rails arranged parallel to one another and spaced apart from one another. This makes it easy to create a pull-out guide with increased stability and load-bearing capacity. Further preferably, the pull-out guide is designed as an over-extension.With such an over-extension mechanism, the first shelf section can be moved far enough out of the cabinet's interior that parts of the second shelf section also partially protrude beyond the opening in the extended position. This further improves accessibility to the multi-section shelf in the extended position.

[0031] Preferably, the first guide device is arranged asymmetrically in the direction of the side of the first shelf section facing away from the second shelf section in the storage position. In particular, it is arranged on the side of the coupling pivot axis on the first shelf section facing away from the second shelf section in the storage position. The asymmetric arrangement of the first guide device on the first shelf section enables the coupling device with the coupling pivot axis to be arranged on the first shelf section in a simple manner. This arrangement enables the coupling device to be pivoted about the coupling pivot axis without any risk of collision with the first guide device. The pull-out device can be implemented in a particularly simple manner.

[0032] Particularly preferably, the first guide device comprises an outrigger, via which the first shelf section is secured to the first guide device. The outrigger enables the first shelf section to be connected more centrally to the asymmetrically offset guide device. This enables the first shelf section to be accommodated centrally, in particular closer to the center of gravity of the first shelf section. The tilting moments acting on the first shelf section due to objects standing on the first shelf section are reduced in this arrangement. The first shelf section is designed to be more stable in a simple manner. The extension device has a simpler construction.

[0033] In an alternative, preferred embodiment, the first guide device comprises two pull-out guides arranged parallel to and spaced from each other, with the coupling pivot axes located between the two pull-out guides. This provides a simple way to create a first guide device with increased stability and load-bearing capacity.

[0034] The coupling device is particularly preferably designed such that it is arranged between the first guide device and the first shelf section in the storage position of the pull-out device.

[0035] Further preferably, the coupling device comprises a flat connecting rod. A flat connecting rod can be arranged particularly easily in the storage position between the first guide device and the first shelf section. The pull-out device can be obtained in a simple manner.

[0036] The coupling device further preferably comprises a guide element for the connecting rod. The guide element is preferably arranged on the underside of the first shelf section, in particular adjacent to the outer contour of the first shelf section. The guide element has a sliding surface and forms a collision barrier between the connecting rod and the first guide device. The reliability of the extension device is increased. In particular, the sliding surface is designed to support an underside of the connecting rod. This improves the supporting effect of the coupling device for the second shelf section. Alternatively or additionally, when using a corresponding sliding surface supporting the underside of the connecting rod, the connecting rod can be designed to be particularly flat and yet a sufficient supporting effect of the coupling device for the second shelf section can be achieved.

[0037] Preferably, the first shelf section is rigidly mounted on the first guide device. While the second shelf section is pivotally connected to the second guide device about a pivot axis, the first shelf section can be rigidly connected to the first guide device. The pull-out device has a simpler design. The stability of the pull-out device and the load-bearing capacity of the first shelf section are increased in a simple manner.

[0038] Preferably, the first shelf section has a substantially rectangular basic shape. This allows for the best possible use of the available space in the interior of a cabinet. The total shelf area can thus be maximized.

[0039] Preferably, the first shelf section has a convex portion of the outer contour on its rear side facing the second shelf section in the extended position. Such an outer contour of the first shelf section with a convex portion on the rear side enables the pivoting movement of the second shelf section about the coupling pivot axis from the position arranged next to the first shelf section in the storage position to the position arranged behind the first shelf section in the extended position, while maximizing the total shelf area.

[0040] Preferably, the second shelf section has an outer contour with a concave section on its front side facing the first shelf section in the extended position. A front-side outer contour of the second shelf section with a concave section enables the pivoting movement of the second shelf section about the coupling pivot axis from the position arranged next to the first shelf section in the storage position to the position arranged behind the first shelf section in the extended position, while maximizing the total shelf area.

[0041] InIn an alternative embodiment, the first shelf section has a rectangular contour in the front area in the extension direction, which is followed by a semicircular contour in the rear area in the extension direction. This easily achieves a visually appealing, particularly symmetrical design of the first shelf section, with the outer contour allowing the second shelf section to pivot about the coupling pivot axis relative to the first shelf section and a design of the second shelf section that enables a correspondingly large combined area of ​​the first and second shelf sections.

[0042] Particularly preferably, both the first shelf section on the rear side have an outer contour with a convex section, and the second shelf section on its front side facing the first shelf section in the extended position has an outer contour with a concave section. This allows the gap between the first shelf section and the second shelf section to be reduced in the extended position of the pull-out device. The total shelf surface is enlarged, and the appearance of the pull-out device in the extended position is improved.

[0043] Preferably, the second shelf section is shaped asymmetrically on the rear side facing away from the first shelf section. In this case, the rear side of the second shelf section, in the storage position, is shorter than the front side. This shape maximizes the surface area of ​​the second shelf section and thus the total shelf area.

[0044] The pull-out device preferably has a shelf rail that delimits the multi-part shelf in the region of the respective envelopes of the first shelf section and the second shelf section. A shelf rail serves to protect objects arranged on the shelf from accidentally falling off the shelf. In the previously known pull-out devices with multi-part shelves, the individual shelf sections are each provided with their own shelf rail that delimits the respective shelf section. Such a conventional shelf rail can be made of profiled sheet metal, plastic, or extruded aluminum profiles, the shape of which is adapted to the contour of the respective shelf section to be delimited. In the previously known pull-out devices with multi-part shelves, objects must be arranged on one of the two shelf sections, which limits the possibilities for utilizing the available storage space.In the preferred solution, the multi-part shelf is defined by a single shelf railing assigned to the first and second shelf sections. The shelf railing approximately defines the envelope surrounding the first and second shelf sections, the shape of which, in a top view of the multi-part shelf, continuously changes during movement between the storage position and the extended position.

[0045] The shelf railing, in turn, is designed to continuously change its shape. This makes it flexible. Larger items, in particular, can be arranged across the shelf sections of a multi-part shelf with this type of shelf railing. This improves the utilization of storage space.

[0046] InIn a particularly preferred embodiment, the shelf railing is designed to be variable in length, at least in the area between the first and second shelf sections, in which the shelf railing is not fixed to either of the two shelf sections. This can be achieved by also forming the shelf railing, at least in this area, from an elastically deformable and variable-length material, such as a correspondingly stretchable elastomer. Alternatively or additionally, the shelf railing can also comprise, at least in this area, an arrangement of rigid elements whose orientation and spacing from one another are variable.

[0047] InIn an alternative preferred embodiment, the shelf railing has a constant length. A constant length is also present if the possible change in length is a maximum of 10%, in particular due to manufacturing tolerances and / or the specifically selected connection technology for a shelf railing formed from rigid elements arranged so as to be displaceable relative to one another. Such a shelf railing of constant length is arranged displaceably on the second shelf section relative to the latter. This alternative preferred solution takes advantage of the fact that the multi-part shelf consisting of the first and second shelf sections has wraparound elements with different contours but of constant length when moved between the storage position and the extended position.

[0048] InIn a further preferred embodiment, the pull-out device comprises at least one railing guide fixedly arranged on the second shelf section, wherein the shelf railing is movable relative to the railing guide in the longitudinal direction of the shelf railing. The railing guide guides the shelf railing at a constant height in the direction of gravity, at least when the pull-out device is installed. In particular, the movable guidance is achieved by a suitable selection of the materials of the railing guide and the shelf railing in the form of a sliding bearing. This allows the pull-out guide to be implemented more cost-effectively.

[0049] InIn an alternative, further preferred embodiment, the pull-out device comprises a railing guide arm, which is arranged at one end in a stationary manner on the shelf railing and at the other end on the second shelf section so as to be pivotable about a guide arm pivot axis. Furthermore, such a railing guide arm is variable in length and designed to apply a force to the shelf railing that moves it in the direction of the guide arm pivot axis, i.e., in the direction of the second shelf section, in particular by means of a spring. In particular, the guide arm pivot axis is arranged near a center point of the second shelf section. The pull-out device can also have two or more guide arms. These can be pivotable independently of one another or fixed relative to one another and pivotable together about a common guide arm pivot axis. This provides a pull-out device with less wear.

[0050] The present application also encompasses a pull-out device with both at least one railing guide and at least one railing guide arm.

[0051] The object of the invention is further achieved by a corner cabinet with the above-described pull-out device according to the invention. The corner cabinet has a rectangular interior, approximately half of which is accessible via an opening at the front. The half of the interior located behind the opening forms a storage area, and the adjacent area of ​​the interior forms a corner area, in which the second and first shelf sections of the pull-out device are arranged in the storage position.

[0052] Preferably, the first shelf section is located completely outside the interior of the corner cabinet in the extended position. This makes the first shelf section particularly easy to access. Further preferably, the second shelf section is arranged in the extended position so that it partially protrudes beyond the plane of the opening from the interior. This further improves the accessibility of the shelf in the extended position.

[0053] Preferably, the center point of the circular arc-shaped path is located adjacent to an opening in the corner cabinet. Such a corner cabinet with the pull-out mechanism is particularly simple in construction.

[0054] Further advantages and details of the invention can be found in the following description of the figures with exemplary embodiments of the invention. The figures show schematically: Fig. 1 shows a pull-out device according to the invention in a corner cabinet in the storage position; Fig. 2 shows the pull-out device according to Fig. 1 in a position between the storage position and the extended position; Fig. 3 the illustration according to Fig. 1 with the two-part shelf in the extended position; Fig. 4 to Fig. 6 an alternative embodiment of a pull-out according to the invention in a corner cabinet.

[0055] Parts with the same or similar functions are provided with identical reference numerals where appropriate. Individual technical features of the exemplary embodiments described below can be combined with the features of the independent claims as well as with the features of individual exemplary embodiments described above to form inventive objects.

[0056] Fig. 1shows a plan view of a corner cupboard 2 with the pull-out device 4 arranged therein. The corner cupboard 2 has an interior space 6 that is rectangular in plan. Approximately half of the interior space 6 is accessible via an opening 8 for a corner cupboard door (not shown). Alternatively, the pull-out device can be arranged in the corner cupboard in the manner of a drawer. In this case, the first shelf section 16 forms a drawer. In particular, the first shelf section 16 can be provided with a corresponding panel that covers the opening 8 in the storage position. The half of the interior space 6 arranged behind the opening 8 forms a storage area 10, to which a corner area 12 is connected.

[0057] The pull-out device 4 comprises a multi-part shelf 14, in this case constructed in two parts, with a first shelf section 16 and a second shelf section 18. The first shelf section 16 is connected to the corner cabinet 2 via a first guide device 20 constructed as a pull-out guide 22. The first shelf section 16 is supported on its underside by the first guide device 20. The second shelf section 18 is supported on its underside by a second guide device 24 constructed as a pivot arm 26. The pivot arm 26 is attached to the corner cabinet 2 so as to be pivotable about a pivot arm pivot axis 28. The pivot arm pivot axis 28 is arranged adjacent to the opening 8. The second guide device 24 is designed to guide the second shelf section 18, during a displacement between the storage position and the pull-out position, along a trajectory in the shape of a segment of a circle, the center of which is the pivot arm pivot axis 28.The second shelf section 18 is pivotally connected to the second guide device 24 about a pivot axis 30. The pull-out device 4 further comprises a coupling device 32, via which the first shelf section 16 and the second shelf section 18 of the two-part shelf 14 are connected. The coupling device 32 is fixed to the first shelf section 16 so as to be pivotable about a coupling pivot axis 34.

[0058] The pull-out guide 22 is arranged asymmetrically offset outwards beneath the first shelf section 16. The pull-out guide 22 is arranged beneath that half of the first shelf section 16 which, in the stored position, faces away from the second shelf section 18. The pull-out guide 22 has an outrigger 36, by means of which the first shelf section 16 is secured to the pull-out guide 22. Thanks to the outrigger 36, the asymmetrically arranged pull-out guide 22 nevertheless engages approximately centrally beneath the first shelf section 16. This increases the load-bearing capacity of the first shelf section 16. The pull-out guide 22 is designed as a multi-part telescopic rail and, in particular, as an over-extension rail. The first shelf section 16 is rigidly connected to the first guide device 20. The coupling device 32 is rigidly connected to the second shelf section 18.

[0059] When the two-part shelf 14 is transferred from the storage position to the extended position, the first shelf section 16 is moved in a purely linear movement through the opening 8 of the corner cabinet 2 out of the interior 6 of the corner cabinet 2 via the first guide device 20, designed as a pull-out guide 22. However, the first guide device 20 can also be designed to guide other movements of the first shelf section 16.

[0060] The second tray section 18, connected to the first tray section 16 via the coupling device 32, follows the movement of the first tray section 16 in the manner of a trailer. The second tray section 18 pivots about the coupling pivot axis 34. The coupling device 32 connects the second tray section 18 to the first tray section 16 like a drawbar. Simultaneously, the second tray section 18 is pivoted along a trajectory in the shape of a circular arc by the second guide device 24, designed as a pivot arm 26. The center point of the trajectory in the shape of a circular arc is formed by the pivot arm pivot axis 28 of the pivot arm 26. The second tray section 18 is moved from a position arranged next to the first tray section 16 in the storage position to a position arranged behind the first tray section 16 in the extended position.At the same time, the second tray section 18 is pivoted about the pivot axis 30 relative to the second guide device 24.

[0061] The second guide device 24, designed as a pivot arm 26, describes a circular arc-shaped trajectory with an angle of approximately 125 degrees. This ensures that the second shelf section 18 is not only transferred within the interior 6 from the corner area 12 into the storage area 10, but is also partially moved out of the interior 6 through the door opening 8. The present two-part shelf 14, in particular the second shelf section 18, is in the Fig. 3 The illustrated pull-out position is particularly easy to access. For this purpose, the pull-out guide 22 forming the first guide device 20 is designed as an over-extension. In In the embodiment, this is achieved in that the pull-out guide 22 is a four-part telescopic pull-out.

[0062] When the two-part tray 14 is transferred from the storage position to the extended position, the second tray section 18 is rotated 90 degrees relative to the first tray section 16. At the beginning of the movement, the second tray section 18 undergoes a clockwise pivoting movement in a first movement phase, controlled by the movement of the first tray section 16 and the coupling device 32. In a second phase, the direction of rotation is reversed, and the second tray section 18 undergoes a counterclockwise pivoting movement about the pivot axis 30 relative to the pivot arm 26 forming the second guide device 24.

[0063] The pivot arm pivot axis 28 is arranged adjacent to the opening 8. This makes it possible to transfer the second shelf section 18 with the largest possible shelf surface from the storage position in the corner area 12 of the corner cabinet into the storage area 10 of the corner cabinet and then into the pull-out position. The pivot arm 26 is curved. This allows it to engage around a corner post of the corner cabinet 2 arranged next to the door opening 8 when the pull-out device is in the pull-out position. The pivot arm 26 with the pivot arm pivot axis 28 can be arranged on a side wall of the corner cabinet 2. Alternatively, the pivot arm 26 with the pivot arm pivot axis 28 can be arranged on a support column that is fixed to the floor and / or to a head element of the corner cabinet 2 and / or also to a side wall of the corner cabinet 2.

[0064] Fig. 2shows the corner cabinet 2 with the pull-out device 4 in a position between the storage position and the extended position. It can be seen here how the shape of the first shelf section 16 and in particular of the second shelf section 18 is determined by the rectangular layout of the interior 6 of the corner cabinet 2, as well as the movements of the first shelf section 16 and the second shelf section 18 relative to one another, and in particular of the second shelf section 18 within the interior 6 of the corner cabinet 2. The first shelf section 16 is essentially rectangular. When transferred from the storage position to the extended position, it is guided in a linear movement through the door opening 8 via the first guide device 20, designed as a pull-out guide 22. The dimensions of the first shelf section 16 thus approximately correspond to the dimensions of the storage area 10 of the interior 6 of the corner cabinet 2.The rear corner, which is adjacent to the second tray section 18 in the storage position, has a convex section. As shown in . Fig. 2 As shown, when the pull-out device is moved from the storage position to the extended position, the second shelf section 18 is pivoted relative to the first shelf section 16 via this corner. The opposite rear corner is also convex in the illustrated embodiment, so that the first shelf section 16 is mirror-symmetrical. This design contributes to the high-quality and pleasing appearance of the pull-out device in the extended position.

[0065] The front side of the second shelf section 18 facing the first shelf section 16 is correspondingly concave. This also serves to make the overall shelf surface as large as possible. At the same time, the second shelf section 18 with its concave front side takes up the contour of the first shelf section 16 with its convex back side, so that an attractive appearance is achieved in the extended position. The back side of the second shelf section 18 facing away from the first shelf section 16 is asymmetrical. The right side of the second shelf section 18 in the extended position is shorter than the left side in the extended position. The transitions are designed with curves. This design is chosen so that the overall shelf surface is as large as possible without the second shelf section 18 colliding with the corner cabinet 2 when transferred from the storage position to the extended position.

[0066] This also applies to the design of the front left corner of the second shelf section 18 in the extended position. This corner is bevelled in order to move the second shelf section 18 around the lateral boundary of the opening 8 on the side adjacent to the pivot arm pivot axis 28 and, in particular, to avoid a collision with the corner cabinet post.

[0067] In this case, designs deviating from the design of the first shelf section 16 and the second shelf section 18 shown in the exemplary embodiment are possible. The respective design of the first shelf section 16 and the second shelf section 18, which maximizes the total shelf area, is a function of the arrangement of the pivot axis 30 on the second shelf section 18 and / or the coupling pivot axis 34 on the first shelf section 16. This is also influenced by the arrangement of the center point of the circular segment-shaped trajectory curve.

[0068] The Figures 4 to 6show an alternative embodiment in which the coupling device 32 is implemented by two rods. Both rods are arranged pivotably about the coupling pivot axis 34 on the first shelf section 16. They are spaced apart from each other about respective pivot axes on the second shelf section 18. The rods thus form a triangle with fixed edge lengths and fixed angles. Kinematically, this embodiment does not differ from the aforementioned embodiment according to the Fig. 1 to Fig. 3 . The coupling device 32 remains rigid relative to the second tray section 18 and is only pivotable about the coupling pivot axis 34 arranged on the first tray section 16.

[0069] The Figures 7 to 11 show a further alternative embodiment of a pull-out device 4 installed in a corner cabinet 2. Fig. 7 shows the pull-out device 4 in the storage position. Fig. 11shows the pull-out device 11 in the pull-out position. Fig. 8 to Fig. 10 show various intermediate positions during the movement of the pull-out device 4 from the storage position to the extended position or during the return movement from the extended position to the storage position. The first shelf section 16 has a rectangular contour in the front area, which is followed by a semicircular contour in the rear area. This results in a visually appealing design of the first shelf section 16, which nevertheless allows for good pivotability of the second shelf section 18 about the coupling pivot axis 34 of the coupling device 32.

[0070] In this embodiment, the first guide device 20 has two parallel pull-out guides 22. The pull-out guides 22 are arranged on the underside of the first shelf section 16. This makes it easy to realize a pull-out device 4 that is particularly stable and resilient. In this embodiment, the coupling pivot axis 34 is arranged between the two pull-out guides 22, so that the coupling device 32 can be in the Fig. 7 illustrated storage position between the first shelf section 16 and the pull-out guide 22 arranged between the coupling pivot axis 34 and the second shelf section 18. For this purpose, the coupling device 32 has a particularly flat connecting rod 33. Another embodiment of the first guide device 20, for example with only one pull-out guide 22 as in the embodiments according to Fig. 1 to Fig. 6 , is also possible as an alternative.

[0071] The coupling device 32 of this exemplary embodiment comprises a guide element 35. This forms a sliding surface for the connecting rod 33 of the coupling device 32, which supports the connecting rod 33 on its underside. Furthermore, the guide element 35 forms a collision barrier that prevents the connecting rod 33 from coming into contact with the pull-out guide 22 when the pull-out device 2 is moved from the storage position to the extended position and back. The reliability of the pull-out device 2 is improved. For this purpose, the guide element 35 is arranged on the underside of the first shelf section 16.

[0072] In this embodiment, the second guide device 24 is further formed with a pivot arm 26, which is arranged in the same plane as the second shelf section 18. This ensures that the pivot arm 26 can cross the first pull-out guide 20 when the pull-out device 4 is moved into the pull-out position and does not collide with it. This is shown in the Figures 10 and 11shown. The pivot arm 26 is very strongly angled and its shape takes up the shape of the second shelf section 18. The second shelf section 18 is encompassed by the pivot arm 26 in the storage position. The pivot axis 30 is arranged on the second shelf section 18 outside the outer contour of the latter. The second guide device 24 has for this purpose a support element which is arranged on the underside of the second shelf section 18 and, together with the pivot arm 26, forms the pivot axis 30. The pivot axis 30 or the support element are arranged in the position of the pull-out device 2 at the rear end of the second shelf section 18 facing away from the opening 8. This arrangement of the pivot axis 30 also ensures that the pull-out device 4 in the Fig. 11 shown extended position compared to the embodiments according to Fig. 1 to Fig. 6can be moved even further beyond the level of the opening 8 out of the corner cabinet 2. Accessibility, particularly of the second shelf section 18 in the extended position, is thereby further improved.

[0073] In this embodiment, the drawer guides 22 are designed as five-part telescopic slides. Five-part telescopic slides can be easily created by combining two three-part telescopic slides. The use of five-part telescopic slides allows for a particularly large extension. This is also referred to as over-extension.

[0074] The second shelf section 18 is supported on the corner cabinet 2 by the second guide device 24. Furthermore, the second shelf section 18 is supported on the first shelf section 16 via the coupling device 32 and, in turn, on the corner cabinet 2 via the first guide device 20. The support of the second shelf section 18 via the connecting rod 33 of the coupling device 32 is assisted by the guide element 35, which forms a sliding surface for the connecting rod 33. This allows the loads in the area of ​​the coupling pivot axis 34 to be reduced compared to a solution without such a guide element 35. The load-bearing capacity of the second shelf section 18 is thereby increased.

[0075] In the Fig. 12 to Fig. 16 The drawer guide 4 is in accordance with Fig. 7 to Fig. 11installed in the manner of a drawer in a corner cupboard 2. When the pull-out guide 4 is installed in the manner of a drawer, the arrangement of the second pivot arm 26 of the second guide device 20 in the same plane in which the second shelf section 18 is arranged is particularly advantageous. This makes it possible to achieve a vertically compact design of the pull-out guide 4 and thus of the drawer. In a pull-out guide 2 designed in the manner of a drawer, a panel is arranged on the first shelf section 16. In the storage position, the panel closes at least part of the opening 8 of the corner cupboard 2 in terms of height. In terms of width, the opening 8 is preferably completely closed by the panel.

[0076] Fig. 17 to Fig. 22 show a drawer guide 4 according to Fig. 7 to Fig. 11, which is provided with a shelf railing 38, once in a top view and once in a view obliquely from above, in which the shelf railing 38 can be seen more clearly. The shelf railing 38 comprises both shelf sections 16 and 18. There is no shelf railing between the shelf sections 16 and 18. In particular, large objects can thus be arranged across the multi-part shelf 14, spanning the shelf sections. The space utilization of the pull-out device is improved. In principle, this advantage is achieved at the expense of the fact that small objects can then unintentionally fall off the multi-part shelf 14 in the area between the two shelf sections 16 and 18.

[0077] In the representations of the Fig. 17 to Fig. 19A top view shows that the flexible shelf rail 38 assumes different contours when the pull-out guide 4 is moved. The overall length of the shelf rail 38 remains approximately constant. The shelf rail 38 is fixed in the front area of ​​the first shelf section 16. In the rear area of ​​the first shelf section 16, the shelf rail 38 wraps around different sections on the left and right edges of the first shelf section 16 when the pull-out device 4 is moved between the extended position and the storage position.

[0078] Depending on the design of the shelf railing 38, it can also be fixed to the second shelf section 18. However, this requires that the shelf railing 38 is highly variable in length in the area between the two shelf sections 16 and 18.

[0079] Alternatively, the shelf railing 38 is arranged on the second shelf section 18 so that it can be displaced relative to the latter in its longitudinal direction. For this purpose, railing guides can be arranged at fixed intervals on the outer contour of the second shelf section 18 at specific intervals. These railing guides preferably guide the shelf railing along the contour of the second shelf section 18 as sliding bearings.

[0080] Alternatively or additionally, railing guide arms can be arranged, in particular on the underside of the second shelf section 18, which are arranged at one end in a stationary manner on the shelf railing and at the other end pivotably about a guide arm pivot axis on the second shelf section 18. Such railing guide arms are variable in length and are designed to apply a force to the shelf railing, in particular by means of a spring, which moves it in the direction of the guide arm pivot axis, i.e. in the direction of the second shelf section. Such railing guide arms can also be used to guide the shelf railing 38 along the outer contour of the second shelf section 18 when the pull-out device 4 is moved between the pull-out position and the storage position.
