[0001] Arrangement for moving at least one cover element
[0002] The present invention relates to an arrangement for moving at least one cover element, preferably a door or folding door, according to the features of the preamble of claim 1.
[0003] Furthermore, the invention relates to a furniture part with such an arrangement.
[0004] Arrangements of the above-mentioned type are used to store or lower doors or hinged doors of a piece of furniture, such as a kitchen or living room cupboard, in a space-saving manner into a section or cavity of the piece of furniture, so that the door(s) do not disturb an operator in an open position and the interior of the piece of furniture is freely accessible.
[0005] In order to move the door(s) from a cavity into an open position, a combination of a translational and a rotational movement around a pivot axis is necessary, whereby the movement of the door(s) is usually initiated and controlled by an operator.
[0006] When moving the door(s) from a retracted or lowered position to an open position, and vice versa, it is usually necessary to deflect the door(s) by an angle of 90°.
[0007] From the prior art, such as from patent specification EP 2740870 B1, arrangements are known which comprise a type of guide rail and guide frames by means of which a folding door is guided from a retracted position to an open position. A disadvantage of such solutions is that the deflection function is only available for folding doors with at least two leaves or cover elements.
[0008] Another disadvantage is that the operator must exert force on the door(s) during the reversing phase to overcome a certain frictional resistance of the guide elements. At the same time, this means that the operator must actively perform an action to swing the door(s).
[0009] Furthermore, unpleasant friction noises or jamming may occur due to the guide elements rubbing against each other, particularly as the use or service life of the arrangement increases.
[0010] The object of the present invention is therefore to provide an arrangement which is improved compared to the prior art and which increases the operating comfort for the operator, enables a gentle, noiseless and component-friendly deflection movement and whose function is given both for doors with one and with several leaves.
[0011] Furthermore, a furniture part with such an improved arrangement is to be specified.
[0012] This object is achieved by the features of claims 1 and 1 .
[0013] The arrangement for moving at least one cover element, preferably a door or folding door, relative to a fixed piece of furniture, which has at least one, preferably shaft-shaped, cavity for receiving the cover element and at least one interior space, which can be covered at least in part by the cover element, has at least one guide device for the translational movement of the cover element within the cavity, at least one support movable along the guide device and at least one pivoting device, wherein the cover element can be pivotally mounted on the support about a pivot axis parallel to the support by means of the pivoting device, and wherein the arrangement has at least one deflection device which is designed such that a translational movement of the cover element along the guide device can be converted into a pivoting movement about the pivot axis,wherein the at least one deflection device comprises at least one delay device.,
[0014] A first major advantage of the arrangement according to the invention is the automatic initiation of the deflection or pivoting of the at least one cover element or the door(s) by the deflection device in the direction of the closed position of the door(s), in which closed position the door(s) cover at least part of the interior of the furniture part.
[0015] The deflection of the door(s) is advantageously carried out without any effort by the operator, which increases user-friendliness.
[0016] The deflection movement is initiated by an impulse in the direction of the closed position, whereby the impulse is initiated by the deflection device.
[0017] In other words, the deflection device is an angular momentum or moment sensor or angular momentum or moment initiator.
[0018] A second major advantage of the invention is that no guide elements or the like are necessary for the deflection of the door(s), since the deflection device converts the translational movement of the door(s) into a pivoting movement by means of an impulse.
[0019] Since there are no guide elements, advantageously no friction noises and / or jamming or the like can occur during the deflection phase.
[0020] Furthermore, the at least one delay device enables a smooth and controlled closing movement of the door(s).
[0021] On the one hand, this avoids any impact noises that may occur, for example, when the door(s) are completely closed.
[0022] On the other hand, this allows for a more gentle operation of the components, which in turn enables the door(s) to move smoothly over the long term.
[0023] An automatic, controlled and smooth movement of the door ( s ) also increases the ease of use.
[0024] A piece of furniture can, for example, be a single cupboard in a wall unit with several cupboards, whereby, for example, a hollow space can be arranged between two cupboards into which the front doors of the cupboards can be lowered.
[0025] The deflection device is preferably aligned in relation to the furniture part in such a way that it extends in the depth direction of the cavity and / or its movable and / or displaceable components are movable at least in the depth direction.
[0026] The interior of the furniture part is essentially the storage space usable by an operator. To guide the door(s), particularly in a translational direction parallel to at least one side wall of the furniture part, a combination of guide rails and at least one support movable therealong, particularly a vertical support or beam, is preferably provided.
[0027] To stabilize the at least one support and / or the door(s) and / or to ensure low-friction and / or controlled movement of the support and / or the door(s), various combinations of bearings, rollers, guide rails, stiffeners or the like can be used.
[0028] The at least one pivoting device, such as a hinge, serves, for example, to pivot the door(s) in a stable and / or controlled manner about a pivot axis.
[0029] The pivot axis is preferably substantially a vertical axis which may run parallel to the support.
[0030] The pivot axis is generally translationally displaceable, i.e. it can, for example, move with the at least one pivoting device and / or the at least one support when the door(s) move.
[0031] The movement of the pivot axis may depend on the design of the individual elements, such as the pivot device and / or the support and / or the relative arrangement of the individual elements to one another.
[0032] Further advantageous embodiments of the invention are defined in the dependent claims. It is particularly preferred that the deceleration device has at least one stop, preferably movable over a limited distance.
[0033] The limited path within which the at least one stop is movable preferably runs at least parallel to the translational direction of movement of the door(s) and / or the guide device.
[0034] The at least one stop can be understood, for example, as a protruding step or nose.
[0035] It is particularly preferred that the deceleration device comprises at least one damping device, preferably comprising at least one damper.
[0036] It is particularly preferred that the delay device comprises at least one spring element with which at least one force can be exerted on the cover element in the direction of a completely retracted position of the cover element in the cavity.
[0037] In the fully retracted position, the at least one cover element, such as the door or folding door, is located substantially completely in the cavity and / or in the lowest possible position, which is delimited, for example, by a rear wall of the furniture part or by an ejection element and / or another delimiting component.
[0038] The at least one spring element has at least one return function, which at least briefly pulls or pushes the cover element toward the fully retracted position. The return function of the spring element can assist the pivoting process and / or move the at least one cover element toward the closed position.
[0039] In a preferred embodiment, the at least one spring element can be designed such that a completely closed position of the door(s) is achieved, so that the spring element has a closing function.
[0040] The spring element can therefore also have a closing function in addition to the reset function.
[0041] For example, the closing function can be achieved by a relatively strong or stiff spring of the spring element.
[0042] However, it is also possible that the closing function can be achieved by another mechanism, such as extending the spring element and / or increasing the distance between the connection points of the spring element.
[0043] It can also be provided that the deceleration device has at least one stop and / or a damping device and / or a spring element.
[0044] It is preferably provided that the deceleration device has at least one receiving element for at least one stop and / or at least one damping device and / or at least one spring element.
[0045] It is preferably provided that the deceleration device has a deceleration device plate that can be fastened to the furniture part, by means of which the deceleration device can be fastened at least indirectly to the furniture part. The fastening of the deceleration device and / or the deceleration device plate to the furniture part can be positively and / or materially connected and / or by means of screws or the like.
[0046] The receiving element and / or the delay device plate can, for example, comprise at least one receiving cylinder for the spring element and / or the damping device.
[0047] It is particularly preferred that the deflection device has at least one hook element which can be arranged on the cover element, preferably offset from the pivot axis, and which can be brought into engagement with the delay device, preferably by means of at least one driver lug.
[0048] It is preferably provided that the deflection device has at least one driver device to which the at least one hook element is or can be connected pivotably about the pivot axis, preferably by means of an axis element.
[0049] The hook element can be regarded as a rotationally mounted lever arm which engages with the delay device at least temporarily, in particular at the moment the deflection device imparts an impulse to the cover element in the direction of the closed position.
[0050] Particularly preferably, the mutual engagement of the driver device and the delay device takes place by means of the driver nose of the hook element of the driver device and the stop of the delay device.
[0051] It is particularly preferred that the driver device is fastened or can be fastened at least to the cover element, for example in a form-fitting and / or material-fitting manner. It is preferred that the driver device has a driver plate fastened or can be fastened to the cover element for fastening the driver device to the cover element.
[0052] The deceleration device and / or the driver device can be fastened to the furniture part and / or to at least one cover element, for example, by means of screws, nails, bolts or the like.
[0053] Protection is also sought for a furniture part with at least one, preferably shaft-shaped, cavity for receiving a cover element, preferably a door or folding door, at least one interior space which can be covered at least in part by the cover element, and an arrangement for moving the cover element relative to the furniture part.
[0054] It is particularly preferred that the at least one delay device is attached to a side wall of the furniture part delimiting the cavity.
[0055] It is particularly preferred that the at least one driver device is fastened to the cover element.
[0056] It is particularly preferred that the furniture part has at least one ejection device for ejecting the cover element from the cavity, in particular from a fully retracted position or a partially retracted position into an open position.
[0057] Particularly preferably, the at least one ejection device is arranged in the region of the cavity opposite the deflection device, i.e., preferably in the rear region of the cavity. Preferably, the at least one ejection device is attached to a side wall of the furniture part that delimits the cavity.
[0058] The at least one ejection device can preferably be activated by an operator exerting force, in particular pressure. This means that the ejection process can preferably be initiated by exerting pressure on the ejection device.
[0059] The ejection device may also have a damping function.

[0072] Figure 1 shows an embodiment of a furniture part 3 with an arrangement 1 for moving at least one cover element 2 or a door, relative to the fixed furniture part 3, which has at least one, preferably shaft-shaped, cavity 4 for receiving the cover element 2 and at least one interior space 5, which can be covered at least in part by the cover element 2, wherein the arrangement 1 has at least one guide device 6 for the translational movement of the cover element 2 within the cavity 4, at least one support 7 movable along the guide device (6) and at least one pivoting device 8, wherein the cover element 2 by means of the pivoting device
[0073] 8 is pivotally mounted on the support 7 about an imaginary pivot axis 9 parallel to the support 7 , and wherein the arrangement 1 has at least one deflection device 10 which is designed such that a translational movement of the cover element 2 along the guide device 6 is converted into a pivoting movement about the pivot axis
[0074] 9 is convertible, wherein the at least one deflection device 10 comprises at least one deceleration device 11.
[0075] In this embodiment of a furniture part 3 with an arrangement 1, the cover element 2 is in an open position 32.
[0076] In this embodiment of a furniture part 3, which can also be part of a larger piece of furniture, such as a wall unit or a fitted kitchen, the at least one delay device 11 is fastened to a side wall 22 of the furniture part 3 delimiting the cavity 4.
[0077] The cavity 4 is not necessarily completely surrounded by side walls 22, but can also be open on several sides.
[0078] In this embodiment, the furniture part 3 has an ejection device 23 for ejecting the cover element 2 from the cavity 4, wherein the ejection device 23 is advantageously and / or expediently arranged in the region of the cavity 4 opposite the deflection device 10 and wherein the ejection device 23 is fastened to a side wall 22 of the furniture part 3 delimiting the cavity 4.
[0079] The following figures and the associated descriptions relate to the exemplary embodiment of a furniture part 3 and / or an arrangement 1 shown in Figure 1. To avoid repetition, the differences from the exemplary embodiments already described will be discussed primarily. Otherwise, the above description of the first exemplary embodiment of a furniture part 3 and / or an arrangement 1 also applies, where applicable, to the figures described below.
[0080] Figures 2 and 3 show an embodiment variant of a deflection device 10, wherein Figure 3 is an exploded view of the arrangement 1 shown in Figure 2.
[0081] In this embodiment of a deflection device 10, the deceleration device 11 has at least one damping device 13 and at least one spring element 14.
[0082] With the spring element 14, at least one force can be exerted on the cover element 2 in the direction of a completely retracted position 30 of the cover element 2 in the cavity 4.
[0083] In this embodiment of a deflection device 10, the deceleration device 11 has two stops 12, which are preferably movable over a limited path and which are essentially movable together with the damping device 13 and / or the spring element 14.
[0084] In the exploded view of the embodiment variant of Figure 3, it can be clearly seen that the at least one stop 12 is arranged on the damping device 13 and / or on the spring element 14.
[0085] In this embodiment of a deflection device 10, the deceleration device 11 has at least one receiving element 15 for at least one stop 12 and / or at least one damping device 13 and / or at least one spring element 14.
[0086] In this embodiment of a deflection device 10, the deceleration device 11 has a deceleration device plate 16 which can be fastened to a furniture part 3 and by means of which the deceleration device 11 can be fastened at least to the furniture part 3.
[0087] In this embodiment of a deflection device 10, the deflection device 10 has at least one hook element 17 arranged on the cover element 2, preferably offset from the imaginary pivot axis 9, which can be brought into engagement with the delay device 11, preferably by means of at least one driver lug 18.
[0088] In this embodiment of a deflection device 10, the deflection device 10 has at least one driver device 19, to which the at least one hook element 17 is or can be connected, preferably by means of an axis element 20, pivotably about the pivot axis 9.
[0089] In this embodiment of a deflection device 10, the driver device 19 can be fastened at least to the cover element 2.
[0090] In this embodiment of a deflection device 10, the driver device 19 has a driver plate 21 that can be fastened to the cover element 2 for fastening the driver device 19 to the
[0091] Cover element 2 on .
[0092] Figure 4 shows a plan view of an embodiment variant of a deflection device 10 and Figure 5 shows a plan view of a representation of a deflection mechanism corresponding to the deflection device 10 shown in Figure 4.
[0093] The mechanism illustrated in Figure 5, in which the landing of a boat anchor on the lake bed creates an impulse on the boat and the boat pivots around the anchor point, is intended to reflect the mechanism of the pivoting movement of the cover element 2 shown in Figure 4 in relation to the furniture part 3 or the side wall 22, wherein the mechanism is initiated by the deflection device 10 by means of an impulse.
[0094] The systems shown in Figures 4 and 5 are therefore similar in terms of their pivoting mechanisms, the landing of the anchor on the seabed corresponding to the point in time at which the driving lug 18 of the driving device 17 hits the at least one stop 12 of the deceleration device 11, and an impulse is given, as a result of which the boat pivots around the anchor point or as a result of which the cover element 2 pivots around the pivot axis 9 and in the direction of the closed position 33 due to its inertia.
[0095] Generally speaking, a sudden deceleration converts the mass inertia of the boat or the cover element 2 into a rotational movement.
[0096] Figure 6 largely shows the embodiment of a furniture part 3 with an arrangement 1 already shown in Figure 1 in a perspective view and the deflection device 10 contained therein in a close-up. Since the cover element 2, to which the driver device 19 is theoretically advantageously attached, has been omitted in this figure, the deflection device 10 is more clearly visible.
[0097] Figures 7 to 13 show perspective views of a sequence of movement of a cover element 2 from a fully retracted position 30 to a closed position 33.
[0098] In the exemplary embodiment of an arrangement 1 shown in these figures, it is conceivable that the ejection device 23 can be activated by exerting pressure, so that the cover element 2 can be moved from the fully retracted position 30 into a partially retracted position 31 and further into an open position 32. This process corresponds to the transition from Figure 7 to Figure 8 and further to Figure 9.
[0099] In this embodiment, the translational movement of the cover element 2 takes place in particular by means of the carrier 7, which is directly pushed by the ejection device 23 and is movable along at least one guide device 6.
[0100] If the cover element 2, as shown in Figure 10, is positioned substantially outside the cavity 4, the angular momentum is generated by the deflection device 10, so that the cover element 2 is pivoted about a pivot axis 9 in the direction of the closed position 33. The pivoting process corresponds to the transition from Figure 10 to Figure 12 and further to Figure 13, wherein the closed position 33 is reached in the sequence - last Figure 13.
[0101] Figures 14 to 20 now show plan views of the movement sequence shown in Figures 7 to 13 of an arrangement 1 or a cover element 2 from the fully retracted position 30 into the closed position 33.
[0102] The position of Figure 14 corresponds to that of Figure 7, the position of Figure 15 to that of Figure 8, the position of Figure 16 to that of Figure 9, etc.
[0103] In these figures, particular attention is paid to the detailed states and / or relative positions of the ejection device 23 and / or the deflection device 10.
[0104] In Figure 14 (corresponds to Figure 7), the cover element 2 is in the fully retracted position 30, with the carrier 7 being in the lowest possible position of the cavity 4, the lowest possible position being limited by a maximally retracted ejection element 24.
[0105] In a preferred embodiment of the ejection device 23, in the fully retracted position 30, a spring or the like provided for ejection is locked in a pre-tensioned state, which lock can be unlocked, for example, by applying pressure, so that the ejection element 24, after unlocking, carries out a pushing movement on the cover element 2 and / or the carrier 7.
[0106] In the fully retracted position 30 shown in Figure 14, all sub-elements are at rest, including the cover element 2, the ejection device 23 and the deflection device 10.
[0107] This means that the deceleration device 11 of the deflection device 10, in particular the at least one damping device 13 and / or the at least one spring element 14, is preferably in a relaxed state. In Figure 15 (corresponds to Figure 8), the cover element 2 is in a partially retracted position 31 after being ejected by the ejection device 23, wherein the cover element 2 has already been partially pushed out of the cavity 4 in a translational manner.
[0108] In this position, the ejection device 23 and / or the deflection device 10 is preferably in a relieved and / or relaxed state.
[0109] In Figure 16 (corresponds to Figure 9), the cover element 2 is now in an open position 32 and essentially at a time at which the angular momentum is transmitted by the deflection device 10.
[0110] In this embodiment of an arrangement 1, the angular momentum is initiated by abutments and / or mutual engagement of the driver nose 18 of the hook element of the driver device 19 with the at least one stop 12 of the deceleration device 11.
[0111] Due to the angular momentum, the cover element 2 pivots about a pivot axis 9 in the direction of the closed position 33, which essentially corresponds to the transition from Figure 16 to Figure 17.
[0112] During the pivoting movement or during the transition from Figure 16 to Figure 17, the damping device 13 and / or the spring element 14 is loaded and / or tensioned, which is illustrated by the different lengths of the damping device 13 and / or the spring element 14.
[0113] This means that the mutual abutment and / or engagement of the hook element 17 and the driving nose 18 can be dampened by means of the damping device 13 and / or by means of the spring element 14.
[0114] In this way, a smoother pivoting movement of the cover element 2 can be achieved.
[0115] By means of the damping device 13 and / or the spring element 14, a restoring effect can also be achieved, whereby the cover element 2 can be moved more easily in the direction of the closed position 33 and / or into the closed position 33.
[0116] Figure 18 shows a further open position 32, which follows the position of Figure 17 and is closer to the closed position 33 and wherein the delay device 11 has in particular a damping function.
[0117] The position of Figure 18 is followed by that of Figure 19, wherein the delay device 11 in Figure 19 has at least one reset function. This means that the delay device 11 retracts the driver device 19 by a certain distance toward the fully retracted position VS by means of the engagement of the stop 12 and the driver lug 18.
[0118] The position of Figure 19 is followed by one of Figure 20, wherein the cover element 2 is now in the closed position 33 and covers the interior 5 of the furniture part 3.
[0119] Here, the deceleration device 11, in particular the damping device 13 and / or the spring element 14, is in a relieved and / or relaxed state.
[0120] During the pivoting process of the arrangement 1 according to the sequence of Figures 14 to 20 (corresponds to the sequence of Figures 7 to 13), the cover element 2 is pivoted and moved in translation through an angle of 90°.
[0121] It is also possible for the at least one cover element 2 to be multi-part and / or multi-leaf, wherein, for example, in the case of the double-leaf or folding door, at least one spreading unit can also be provided.
[0122] It is also conceivable that the arrangement 1 comprises further drive units for moving the cover element 1.
