Description

Technical Field

[0001] The invention relates to a device for the translational and rotational movement of an object having a planar support area relative to a support area of ​​a carrier panel arranged plane-parallel to the support area plane according to the preamble of claim 1 .

[0002] The device also relates to a piece of furniture or a household appliance. Background Art

[0003] A generic device is known, for example, from DE 10 2017 106 170 A1.

[0004] In DE 10 2017 106 170 A1, a translational-rotational bearing is used to perform translational and rotational movements. The translational-rotational bearing essentially comprises two plates formed with running channels in which balls are guided. The running channels are designed so that they allow translational and rotational movements of one plate relative to the other through a predetermined angle.

[0005] The translational movement of the panels relative to each other and the axial fixing are also allowed by a rectilinear slot provided in one plate, in which the connecting studs attached to the other plate are guided.

[0006] A problem with this design with a large difference between the length and width of the article is that a tilting force is generated when the article is in or near the 90° pivot position, where the article protrudes most over the front edge of the load-bearing panel. In this case, the article may preferably be in the form of a shelf.

[0007] This means that there is a risk of the shelf tilting over the edge of the load-bearing panel, especially when heavier items are placed on the part of the shelf that protrudes over this edge. Summary of the Invention

[0008] The object of the present invention is to further develop a device for the translational and rotational movement of an object having a flat support area relative to a support area of ​​a support panel which is arranged plane-parallel to the support area, wherein the support surfaces of the support areas facing each other have corresponding running channels in which the rolling contact bodies are guided so that tilting forces that occur even in the case of minimal overlap of the object relative to the support panel can be better absorbed.

[0009] This object is solved according to some embodiments of the invention by a device for translational and rotational movement of an object having a planar support area relative to a support area of ​​a carrier panel arranged plane-parallel to the support area.

[0010] The device according to the invention has corresponding running channels for guiding rolling contact bodies on the mutually facing bearing surfaces of the bearing region, wherein the length of the object, viewed in the plane of the bearing surfaces, is greater than its width.

[0011] The running channel is formed so that when a force is applied to the article in a direction defined in the plane of the support area, the article can be moved from a starting position to a final position relative to the carrying panel in a first pivot direction, wherein the article is pivoted relative to the carrying panel through a predetermined angle between 90° and 180° and can be pivoted back to the starting position in a pivot direction opposite to the first pivot direction.

[0012] A connecting column projects from one of the support areas and is movable in a guide rail arranged in the other of the support areas.

[0013] The connecting column is arranged eccentrically on one of the bearing areas.The guide rail is in the shape of an arc with a varying radius of curvature.

[0014] By means of a device designed in this way, in particular the eccentric arrangement of the connecting strut makes it possible to form a larger lever arm for absorbing the tilting forces that occur, compared to a centrally arranged connecting strut.

[0015] In particular, this enables the use of articles having a larger aspect ratio.The aspect ratio is defined as the ratio of the length to the width of the article in the plane of the support area.

[0016] A total rotation of 180° enables items that are longer than they are wide to be inserted consistently in both levels, such as furniture or household appliances or other items.

[0017] Therefore, the effect of the tilting force generated by the support is greatest in such an arrangement with unequal length and width ratios of the articles when rotated through 90°.

[0018] Due to the eccentric arrangement of the connecting strut, the lever arm formed for absorbing the occurring tilting forces is largest when rotated through 90° compared to a centrally arranged connecting strut.

[0019] Thus, the device for translational and rotational movement of the object can also be pivoted by only 90°, for example, so that the amplified support effect according to the invention counteracts tilting. Thus, alternative devices can have a total rotation angle of less than 180°, for example only 90°.

[0020] The carrying of the goods via the rolling contact bodies guided in the running channel also reduces the manufacturing costs and effortlessly increases the robustness and ease of operation of the device.

[0021] Advantageous embodiment variants of the invention are subject matter of the dependent claims.

[0022] According to an advantageous embodiment variant, the connecting studs are equidistant from the opposite longitudinal edges of the article. In other words, the connecting studs are arranged eccentrically in the longitudinal extension of the article and centrally in the support region of the article in the width extension of the article.

[0023] According to a preferred further development, the connecting stud has a cylindrical neck region, from the free end of which a collar extends, the surface of the collar facing the neck region engaging behind a support surface formed in the guide rail.

[0024] The secure connection thus achieved between the object and the carrying panel in a direction perpendicular to the plane of the support area allows a further improvement in the absorption of tilting forces.

[0025] Particularly preferably, the side edges of the curved path of the guide rail of the connecting end are formed with corresponding support surfaces.

[0026] According to an advantageous further development, a plurality of spaced-apart supporting webs aligned perpendicularly to the plane of the bearing surface are formed integrally with the respective supporting surface on the inner edge of the end of the guide rail.

[0027] According to a further preferred embodiment variant, at least one elastic tongue is formed on each of the inner edges of the end portions of the guide rail, which tongue can be pressed from the latched position under the action of a force so as to narrow the channel width of the guide rail in the direction of the guide rail edge, wherein the elastic tongue is integrally formed at the level of the neck region of the connecting column, as viewed perpendicular to the plane of the support surface.

[0028] This provides simple tactile feedback to the user that the item has reached its final location.

[0029] According to a further preferred embodiment variant, the curved path of the guide rail is curved in one direction only.

[0030] Particularly preferably, the end of the guide rail in the region of the transition to the curved path is curved in a direction opposite to the curvature of the curved path.

[0031] According to a further advantageous embodiment variant of the invention, the rolling contact bodies are accommodated in a rolling contact body cage having a plurality of rolling contact body receptacles.

[0032] Particularly preferably, the rolling contact element cage has an annular, closed frame region and a support region. The frame region does not extend beyond the edge of the load-bearing panel at any position of the object from its initial position to its final position, so that the rolling contact elements mounted in this portion of the rolling contact element cage always transfer a portion of the load of the object to the load-bearing panel. The support region extends beyond the edge of the load-bearing panel within a predetermined pivot angle range, thereby further supporting the object and preventing it from tilting on the edge of the load-bearing panel.

[0033] The rolling contact body cage thus also contributes to further stabilization with respect to any tilting forces that occur.

[0034] According to a preferred embodiment variant, the items are formed as shelves having a storage surface.

[0035] The furniture or household appliance according to the invention, in particular a refrigerator or freezer, has a main body on which at least one object as described above is arranged. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In the following description of the drawings, terms such as top, bottom, left, right, front, rear, etc. exclusively refer to the exemplary representation and position of selected items, load-bearing panels, rolling contact bodies, rolling contact body cages, guide rails, connecting posts, and the like in the respective drawings. These terms should not be understood restrictively, i.e., these references may vary due to different operating positions or mirror-symmetrical designs, etc.

[0050] exist Figure 1 In the drawing, reference numeral 2 denotes an item which is preferably designed as a shelf and which is mounted on a carrying panel 3 so as to be simultaneously movable in translation and in rotation about a connecting column 9 which serves as a pivot axis and which can be moved along accurately designed guide rails 8 .

[0051] A simultaneous translational and rotational movement is to be understood here as the superposition of a rotational movement of the object around the connecting post and a translational movement of the object along the guide rail with the connecting post.

[0052] The underside of the item 2 designed as a shelf and the upper side of the carrier panel 3 are designed as bearing areas 4, 5. The bearing surfaces of these bearing areas 4, 5 facing each other each have a running channel 41, 51, in which rolling contact bodies 7, preferably in the form of balls, are guided.

[0053] The running channels 41, 51 introduced into the supporting areas 4, 5 of the object 2 and the carrier panel 3 are designed and introduced distributed on the supporting areas 4, 5 so that when a force is applied to the object 2 in a direction A defined in the plane of the supporting area, the rolling contact bodies 7 move the object 2 from the starting position (in the direction A) with a forcibly guided translational and rotational movement. Figure 3 ) moves to an intermediate position pivoted 90° (in Figure 5 ) to a final position pivoted by a further 90°, in which the object 2 is pivoted by a total of 180° relative to the carrying panel 3 in the first pivot direction R1.

[0054] It is also conceivable to design the running channels 41, 51 so that the article 2 can be moved in a first pivot direction R1 from a starting position to a final position pivoted less than 180°, wherein the final position is reached while the article 2 is rotated at least 90° from its starting position, preferably between 130° and 180°.

[0055] Furthermore, the running channels 41, 51 are designed so that the articles 2 only pass the front edge of the carrying panel 3 (at the Figure 3 ), so that such a device can be installed, for example, in a storage compartment of a piece of furniture 11 or a household appliance 12 that is laterally closed from three sides, as in Figure 12 and Figure 13 Example in.

[0056] Furthermore, the object 2 can be pivoted from this end position back to the starting position in a pivoting direction R2 opposite to the first pivoting direction R1 .

[0057] If you can Figures 1 to 3 It can further be seen in Figure 1 that the length L of the article 2 is significantly greater than the width B of the article 2 when viewed in the plane of the support surface.

[0058] If you can Figure 2 As can be seen further in FIG, connecting posts 9 protrude from the support region 4 of the object 2 .

[0059] In the assembled state of the object 2 , the connecting column 9 is movable on the carrying panel 3 in a guide rail 8 arranged in the support region 5 of the carrying panel 3 .

[0060] The receiving width of the guide rail 8 can be greater than the diameter of the portion of the connecting post 9 that extends into the guide rail 8. This enables the clearance of the connecting post 9 in the guide rail to exceed the structural tolerance.

[0061] In addition, if you can Figure 2 As can be clearly seen in FIG, the connecting column 9 is arranged eccentrically on the support area 4 of the object 2. Therefore, the rotation part of the object 2 is interpreted here as a pivoting movement.

[0062] In the present exemplary embodiment, the connecting studs 9 are positioned such that they protrude eccentrically from the support area 4 of the article 2 in the direction of the longitudinal extension L of the article 2 and are centrally located in the direction of the width extension B. The connecting studs 9 are therefore equidistant from the opposite longitudinal edges 22 , 23 of the article 2 .

[0063] The curved guide rail 8 is designed with a varying radius of curvature. The guide rail 8 essentially consists of a curved path 81 that is preferably curved in only one direction, from which respective ends 82, 83 extend, which, in the transition to the curved path 81, bend in a direction opposite to the curvature of the curved path 81.

[0064] In order to securely connect the carrying panel 3 to the object 2, the connecting post 9 has a cylindrical neck region 91 from the free end of which extends a collar 92, the surface 93 of the collar facing the neck region 91 engaging behind the support surfaces 86, 87 formed in the guide rail 8. Figure 10 The support surfaces 86, 87 are shown by way of example in FIG.

[0065] As can be seen in the detail showing one of the ends 82 , 83 of the guide rail 8 Figures 9 to 11 It can further be seen in that the side edges of the curved path 81 of the guide rail 8 connecting the ends 82, 83 to each other are formed with corresponding support surfaces 86, against which the surface 93 of the collar 92 rests in the final position without play in the event of a tilting force being applied.

[0066] Further support surfaces 86 are formed on the inner edges of the ends 82, 83 of the guide rail 8, which are spaced apart from each other, wherein the support webs 85 are oriented perpendicular to the plane of the bearing surface, as can be easily seen in FIG. Figure 10 and Figure 11 It can be seen in.

[0067] In addition, at least one elastic tongue 84 is formed on each inner edge of the ends 82, 83 of the guide rail 8, which can be pressed toward the edge of the guide rail from the latched position of the connecting column 9 under the action of force, thereby narrowing the channel width of the guide rail 8.

[0068] The elastic tongues 84 are formed perpendicularly to the plane of the bearing surface at the level of the neck region 91 of the connecting stud 9 .

[0069] In a preferred embodiment variant shown here, two such elastic tongues 84 are provided which are forced apart when the connecting post 9 enters one of the ends 82, 83 and which hold the connecting post 9 in this final position after it has been fully retracted, so that the connecting post 9 can only be slid out of this final position by applying a predetermined force sufficient to force the elastic tongues 84 apart.

[0070] In particular, Figure 2 and Figure 8 As shown, the rolling contact bodies 7 are received in a rolling contact body cage 6 having a plurality of rolling contact body receptacles 63 and are retained therein in a captured manner.

[0071] Two slightly differently designed embodiment variants of the rolling element cage 6 essentially comprise an annular closed frame region 61 and a support region 62 .

[0072] In this regard, the frame region 61 is shaped and positioned between the support regions 4, 5 such that it does not protrude beyond the edge of the carrier panel 3 in any pivot position, e.g. Figure 1 、 Figure 3 、 Figure 4 and Figure 5 exemplified.

[0073] In contrast, the supporting region 62 of the rolling contact body cage 6 extends beyond the edge of the load panel 3 in order to additionally absorb tilting forces within a predetermined pivot angle range of the object 2 relative to the load panel 3 .

[0074] For example, Figure 4 and Figure 7 As shown, in which the item 2, which is designed here as a shelf, has minimal overlap with the carrying panel 3 or at most protrudes beyond the front edge of the carrying panel 3, in this pivoted position of the item 2, the support area 62 is arranged below the item 2 in such a way that it can additionally absorb tilting forces.

[0075] Figure 12 and Figure 13 The above device is shown in the furniture 11 ( Figure 12 ) or a preferred application in a household appliance 12 designed as a refrigerator or freezer, wherein the object 2 and the carrying panel 3 are arranged in a body 13, 14 of the furniture or household appliance.

[0076] In this case, a fixedly mounted base 15 is preferably arranged in the body 13, 14 of the furniture 11 or household appliance 12, to which base the carrying panel 3 of the device is fixed. It is also conceivable to fasten the carrying panel directly to the body 13, 14.

[0077] It is also conceivable that the article according to the invention and the carrier panel according to the invention are used in the interior of a motor vehicle, such as a caravan, or in the cockpit or trunk of a car.
