Description

[0001] The invention relates to a lid adjuster for a piece of furniture. The lid adjuster comprises a housing, an energy accumulator arranged within the housing, a coupling element coupled to the energy accumulator and driven thereby for movement about an output axis, and an actuating arm arranged on the outside of the housing and coupled to the coupling element such that the actuating arm is driven for rotation about an actuating axis.

[0002] Such a lid adjuster is known from EP 3 719 242 A1. The lid adjuster described therein comprises an actuating arm which is pivotably attached to a base element about an actuating axis between an open position and a closed position. A toggle lever mechanism has a first lever and a second lever which are pivotably connected to one another about a pivot axis. Furthermore, an energy accumulator is provided which applies force to the toggle lever mechanism. The energy accumulator acts on the first lever at a first articulation point spaced from the pivot axis and on the second lever at a second articulation point spaced from the pivot axis, the first articulation point and the second articulation point being subjected to force towards one another by the energy accumulator.An adjusting contour arrangement comprising an adjusting contour and a guide element is arranged between the first lever and the adjusting arm. The guide element is movable along the adjusting contour, and the adjusting arm is subjected to force by the first lever via the adjusting contour arrangement in the direction of rotation about the adjusting axis. The adjusting contour is formed on the first lever, and the guide element is attached to the adjusting arm at a distance from the adjusting axis.

[0003] Lid stays are used to hold upward-opening furniture lids in an open position or to move them toward the open position. Lid stays can also be designed to hold a lid in any desired position.

[0004] There are different opening types for furniture lids. With a folding lift fitting, the lid has an upper lid half and a lower lid half. The upper lid half is attached to an upper edge via one or more hinges on the top panel of a furniture carcass and can pivot about a horizontal pivot axis. The lower lid half is attached to the upper lid half via one or more hinges and can pivot about another horizontal pivot axis. When the lid is closed, the two lid halves are arranged vertically one above the other in a common plane. The folding lift fitting engages a lower end of the lower lid half with an actuating arm, whereby the lid is folded when opened so that the two lid halves are pivoted towards each other and move closer together.

[0005] With a tilt-up fitting, the lid is constructed as a single piece and is supported against the furniture body solely by the lid support. Unlike a folding lid, the lid is not hinged to the top of the furniture body. When opened, the lid moves upwards and pivots around a horizontal pivot axis that moves in the room. The lid can be pivoted over the top of the furniture body.

[0006] With a parallel lift fitting, the lid is also constructed as a single piece and is supported against the cabinet body solely by the lid stay. The lid is not hinged to the top of the cabinet body. When opened, the lid slides parallel, meaning it moves upward while always remaining parallel to its original position.

[0007] These different connection types typically require different angle ranges over which an actuator arm must pivot to drive the lid. Therefore, specially adapted lid actuators are usually provided for different opening types.

[0008] Different energy storage devices are used for the three opening types. If only one energy storage device or lid actuator is to be used for all opening types, concessions must be made with regard to the lid's open position or the utilization of the lid actuator's load-bearing capacity. With a folding lift fitting, the opening angle—i.e., the angle of rotation of the actuating arm from the closed position to the open position—is approximately 110°. With a swivel-lift fitting, the opening angle is approximately 140°, and with a parallel lift fitting, it is 155°.

[0009] If a lid fitting is to be used for all three opening types, it must allow an opening angle of 155°. When used as a folding lift fitting, only 110° of this angle is utilized. This means that the energy stored in the energy storage device is not fully utilized, and the usable weight of the lid is reduced. If a lid fitting with an opening angle of only 110° is used as a parallel lift fitting, it cannot fully open the lid, meaning access to the furniture is restricted due to the lid not being fully open.

[0010] The object of the present invention is to provide a lid adjuster which can be used for different opening types by simple adjustments.

[0011] The problem is solved by a lid adjuster for a piece of furniture, comprising a housing, an energy accumulator arranged within the housing, a coupling element coupled to the energy accumulator and driven thereby to move about an output axis, and an actuating arm arranged on the outside of the housing and coupled to the coupling element such that the actuating arm is driven to rotate about an actuating axis. Furthermore, the lid adjuster has a gear arranged on the outside of the housing and via which the actuating arm is coupled to the coupling element such that an input angle of rotation of the coupling element about the output axis is converted into a different output angle of rotation of the actuating arm about the actuating axis.

[0012] The output angle of rotation can be larger or smaller than the input angle of rotation. It is also possible for the output angle to be identical to the input angle of rotation, in which case the gearbox could be omitted.

[0013] The movement of the coupling element around the drive axis can be a translational movement of the coupling element along a circular path or an arc segment of a circle, with the center of the circular path or circle located on the output axis. Alternatively, the coupling element can also rotate around the drive axis.

[0014] Thus, depending on the maximum opening angle of the coupling element and the required opening type, the lid actuator can be adjusted by appropriately dimensioning the gear unit so that the initial angle of rotation of the actuator arm corresponds to the required opening angle of the opening type. Thus, the lid actuator always covers the full required opening angle.

[0015] In this case, the actuating axis of the actuating arm can be arranged parallel, in particular coaxially, to the drive axis of the coupling element.

[0016] The transmission can have a transmission input element that is torsionally rigidly coupled to the coupling element with respect to the drive axis. The transmission can also have a transmission output element that is torsionally rigidly coupled to the actuating arm with respect to the actuating axis. "Torsionally rigid" means that the two interconnected elements rotate together around the corresponding axis without a difference in the angle of rotation. This also means that, for example, the coupling element can be attached to the transmission input element so that it can rotate about a longitudinal axis of the coupling element that is arranged parallel to the drive axis, but rotates with the latter around the drive axis without any deviation in the angle of rotation.

[0017] The transmission input element can be arranged to be rotatable about the drive axis of the coupling element.

[0018] The transmission can be a gear train, such as a planetary gear or spur gear. Linkage gears or lever gears are also conceivable.

[0019] In the case of a planetary gear, the gear has a sun gear, a planet carrier with planet gears rotatably mounted on it and a ring gear, whereby the gear can be arranged on the actuating arm.

[0020] One of the elements from the group consisting of sun gear, planet carrier, and ring gear forms the transmission input element, and another of the elements from the group consisting of sun gear, planet carrier, and ring gear forms the transmission output element. The third element from this group is preferably fixed and non-rotatable, for example, on the housing of the cover actuator.

[0021] In one exemplary embodiment, the planetary carrier forms the transmission input element, and the ring gear forms the transmission output element. The sun gear can be fixed and non-rotatable, for example, attached to the housing.

[0022] In an exemplary embodiment, the actuating arm can have a gear receiving section that forms the ring gear of the gear or is connected to the ring gear. An actuating section protrudes radially from the gear receiving section relative to the actuating axis and is designed to be coupled to a cover of the furniture at an end remote from the gear receiving section. "Radial" here means that the actuating section extends from the inside to the outside, starting from the gear receiving section. The actuating section does not have to run along a straight, imaginary radius.

[0023] The gear receiving section of the actuating arm can be designed in the shape of a plate, wherein, viewed in the direction of the actuating axis of the actuating arm, the ring gear and the planet gears are arranged on one side of the gear receiving section and the planet carrier is arranged on the side of the gear receiving section facing away from this.

[0024] The sun gear can be connected in a rotationally fixed manner with a bolt, which in turn is rotationally fixed to the housing of the cover actuator.

[0025] The actuating arm with the gear can be supported against the housing and / or the energy storage mechanism exclusively via the coupling element and the bolt. This results in defined and simple support as well as simple installation of the actuating arm and gear to the housing. Furthermore, it is possible to modify the fitting for different opening kinematics by mounting different actuating arms and gears. The energy storage mechanism and the remaining elements do not need to be adapted for this. Since the actuating arm and gear are mounted externally to the housing, the cover actuator can be adjusted using simple means. It is also conceivable to mount an actuating arm without a gear.

[0027] The Figures 1 to 6 To illustrate different opening types, show a furniture body 1 with different lids 2 and lid adjusters 3 adapted to the respective opening type. Figures 1 and 2show a folding lift fitting, figures 3 and 4 a swivel fitting and the Figures 5 and 6 a parallel lift fitting.

[0028] The furniture body 1 is identical in design and is shown in a longitudinal section in each case. The furniture body 1 has a bottom panel 4, a top panel 5, a rear panel 6, and a side panel 7, which form a receiving space 8 of the furniture body 1, which can be closed by the lid 2.

[0029] For a folding lift fitting according to the Figures 1 and 2 The lid 2 has an upper lid half 9 and a lower lid half 10. The upper lid half 9 is pivotably attached to an upper edge 11 via a hinge 12 on the top panel 5 of the furniture body 1 about a horizontal first axis A 1. The lower lid half 10 is pivotably attached to the upper lid half 9 about a horizontal second axis A 2 via a hinge 13. In a closed position of the lid 2 according to Figure 1The two lid halves 9, 10 are arranged vertically one above the other in a common plane. The lid actuator 3 has an actuating arm 14 which is pivotably attached to a housing 15 of the lid actuator 3 about an actuating axis S. The actuating arm 14 is further pivotably connected to the lower lid half 10 about a connecting axis V. Within the housing 15, a force accumulator (not shown here) is arranged, via which force is applied to the actuating arm 14 in the direction of rotation about the actuating axis S in such a way that at least over part of the pivoting path of the actuating arm 14, the lid 2 is moved in the direction of Figure 2 When the cover 2 is moved from the open position shown in Figure 1 shown closed position into the Figure 2 In the open position shown, the lid 2 is folded, whereby the two lid halves 9, 10 are pivoted towards each other about the connecting axis V and approach each other.

[0030] In the Figures 1 and 2 For the opening type of the folding lift fitting shown, an opening angle α of approximately 110° is required for an optimal arrangement of the lid 2 in the open position, in which access to the receiving space 8 of the furniture body 1 is largely unrestricted. The opening angle α corresponds to the angle of rotation of the actuating arm 14 from the closed position ( Figure 1 ) for disclosure ( Figure 2 ).

[0031] With the high swivel fitting according to Figures 3 and 4 The lid 2 is formed in one piece and is supported against the furniture body 1 exclusively by the lid support 3. The lid 2 is not pivotably attached to the top panel 5 of the furniture body 1 via hinges like a folding lid. When the lid 2 is opened, it moves upwards and is pivoted about a horizontal axis that moves in the room. In doing so, the lid 2 is partially pivoted over the top panel 5 of the furniture body 1.

[0032] To enable this movement of the lid 2, an actuating arm 14 is provided, similar to the upward pivot fitting, which is pivotably attached to the housing 15 about an actuating axis S. The actuating arm 14 is further connected to a fastening fitting 16 in the form of a coupling arm, which is firmly attached to the lid 2 and pivotably connected about a connecting axis V. Furthermore, the lid adjuster 3 has a guide arm 17, which is pivotably attached to the housing 15 of the lid adjuster 3 about a first guide axis F1. The guide arm 17 is further pivotably connected to the fastening fitting 16 about a second guide axis F2. The actuating arm 14 and the guide arm 17, together with the housing 15 of the lid adjuster 3 and the coupling arm 16, form a trapezoid.

[0033] As with the folding lift fitting, a force accumulator (not shown here) is arranged within the housing 15, via which force is applied to the actuating arm 14 in the direction of rotation about the actuating axis S in such a way that at least over part of the pivoting path of the actuating arm 14 the cover 2 is moved in the direction of the Figure 4 shown open position is subjected to force.

[0034] In order to enable this movement sequence of the cover 2, the actuating arm 14 and the guide receptacle 17 can also be pivotally connected to the cover 2 via the fastening fitting 16 or two separate fastening fittings in such a way that the connecting axis V and the second guide axis F2 are arranged one above the other and not, as in Figure 3 shown one after the other.

[0035] In the Figures 3 and 4For the type of opening of the swivel fitting shown, an opening angle α of the actuating arm 14 of approximately 140° is to be provided for an optimal arrangement of the cover 2 in the open position, in which access to the receiving space 8 of the furniture body 1 is largely unrestricted.

[0036] With a parallel lift fitting according to the Figures 5 and 6 The lid 2 is constructed in one piece, as in the swivel-up fitting, and is supported against the furniture body 1 exclusively by the lid adjuster 3. The lid 2 is not pivotably attached to the top panel 5 of the furniture body 1 like a folding lid. The lid 2 is displaced parallel when opened, ie the lid 2 is moved upwards, always remaining parallel to the starting position.

[0037] In order to enable this movement sequence of the lid 2, the lid fitting 3 has, similar to the up-swing fitting, an actuating arm 14 and a guide arm 17, which, however, do not form a trapezoid as in a up-swing fitting, but are arranged in the form of a parallelogram to one another.

[0038] As with the folding lift fitting, a force accumulator (not shown here) is arranged within the housing 15, via which force is applied to the actuating arm 14 in the direction of rotation about the actuating axis S in such a way that at least over part of the pivoting path of the actuating arm 14 the cover 2 is moved in the direction of the Figure 6 shown open position is subjected to force.

[0039] In the Figures 5 and 6For the type of opening of the parallel lift fitting shown, an opening angle α of approximately 155° is required for an optimal arrangement of the lid 2 in the open position, in which access to the receiving space 8 of the furniture body 1 is largely unrestricted.

[0040] In order to enable the three opening types shown with one and the same energy storage device, as shown in the Figures 7 to 9 shown, a gear 18 is provided that adapts a maximum output angle of rotation of the actuating arm 14 to the required opening angle α. The Figures 7 to 9 show the lid actuator 3 in different views and are described together below.

[0041] Figure 7 shows the gear 18 without a cover, so that the details of the gear 18 can be seen. In the Figures 8 and 9 the housing 15 is shown without a housing side wall 19, so that the energy accumulator 20, which is arranged within the housing 15, is visible.

[0042] The energy accumulator 20 comprises a compression spring 21 in the form of a helical spring. The compression spring 21 is pivotally connected to a base plate 22 of the housing 15 of the lid actuator 3 and pivotally connected to a lever 23. The compression spring 21 is preloaded against the base plate 22 and against the lever 23.

[0043] The lever 23 is pivotally mounted on the base plate 22 about a lever axis H, with the pivot point of the compression spring 21 on the lever 23 being radially spaced from the lever axis H. The compression spring 21 thus urges the lever 23 in the direction of rotation about the lever axis H.

[0044] The lever 23 has an adjusting contour 24 with which the lever 23 is supported against a coupling element 25 and drives the coupling element 25 to move about an output axis T. As will be explained below, the coupling element 25 is movable along a circular arc about the output axis T.

[0045] The coupling element 25 has a roller 26 which is mounted on a bolt 27 so as to be rotatable about a roller axis R. Thus, during a pivoting movement of the lever 23, the roller 26 can roll along the adjusting contour 24 and thus avoid friction losses.

[0046] The coupling element 25 is coupled to the actuating arm 14 via the gear 18 in such a way that an input angle of rotation of the coupling element 25 relative to the output axis T is converted into an output angle of rotation of the actuating arm 14 about the actuating axis S that differs from the input angle of rotation.

[0047] The gear 18 is attached to the actuating arm 14 and is located outside the housing 15 of the cover actuator 3. The gear 18 is designed in the form of a planetary gear and has a sun gear 28, a planet carrier 29, three planet gears 30 and a ring gear 31.

[0048] The actuating arm 14 has a gear receiving section 32 to which the gear 18 is attached. The gear receiving section 32 is plate-shaped. The planet carrier 29 is arranged on a side of the gear receiving section 32 facing the energy accumulator 20. The planet carrier 29 is rotatably mounted on a bolt 33 about the output axis T of the coupling element 25 and the pivot axis S of the actuating arm 14, wherein the output axis T and the actuating axis S are arranged coaxially to one another. The bolt 33 is connected in a rotationally fixed manner to the base plate 22. The bolt 27 of the coupling element 25 is connected to the planet carrier 29, wherein the roller axis H is arranged parallel and spaced from the output axis T and the actuating axis S.

[0049] The planet carrier 29 is also plate-shaped and arranged between the gear receiving section 32 and the power drive 20. The planet carrier 29 is driven in the direction of rotation about the output axis T via the coupling element 25, which is driven by the power drive 20 about the output axis T.

[0050] On the side of the gear receiving section 32 facing away from the power drive 20, the ring gear 31 is fixedly connected to the gear receiving section 32 coaxially to the pivot axis S. The bolt 33 extends through the planet carrier 29 and through the gear receiving section 32 of the actuating arm 14 and extends into the ring gear 31. The planet carrier 29 and the actuating arm 14 are rotatably mounted on the bolt 33. The sun gear 28 is connected to the bolt 33 in a rotationally fixed manner.

[0051] The planetary gears 30 are arranged between the sun gear 28 and the ring gear 31 such that they mesh with the sun gear 28 on the one hand and with the ring gear 31 on the other. The planetary gears 30 are each rotatably mounted on a bolt 34, wherein the bolts 34 are firmly connected to the planetary carrier 29. For this purpose, circular slots 35, 36 are provided in the gear receiving section 32, through which the bolts 34 extend. The slots 35, 36 have a circumferential length such that the planetary carrier 29 can be rotated sufficiently relative to the gear receiving section 32.

[0052] The planet carrier 29 forms a transmission input element of the transmission 18, which is driven in rotation by the coupling element 25. The ring gear 31 forms a transmission output element of the transmission 18, via which the actuating arm 14 is driven in rotation about the actuating axis S. In the illustrated embodiment with the transmission 18 in the form of a planetary gear, the rotational speed or angular speed of the transmission input element (planet carrier) is converted into a faster rotational speed or angular speed of the transmission output element (ring gear). As a result, an input rotational angle of the coupling element 25 relative to the output axis T, which is arranged coaxially to the actuating axis S, is converted into a larger output rotational angle of the actuating arm 14 relative to the actuating axis S.

[0053] Figure 10shows another embodiment of an actuating arm 14 with gear 18. The gear 18 is also designed as a planetary gear. In contrast to the embodiment according to Figures 7 to 9 all elements of the gear 18 are located on one side of the gear receiving section 32, namely on the side facing the energy accumulator 20.

[0054] Figure 11shows a further embodiment of a cover adjuster 3 with a gear 18 in the form of a spur gear. The gear 18 comprises an input spur gear 38, which is driven by the coupling element (not visible here), wherein the coupling element is passed through a slot 37 in the housing side wall 19 from the interior of the housing 15. The input spur gear 38 meshes with an intermediate spur gear 39, which in turn meshes with an output spur gear 40. The input spur gear 38, the intermediate spur gear 39, and the output spur gear 40 are all attached to the housing 15 so as to be rotatable about axes arranged parallel and spaced from one another. The input spur gear 38 is arranged so as to be rotatable about the output axis T, about which the coupling element is moved. The actuating axis S of the actuating arm 14 is arranged parallel and spaced from the output axis T in this embodiment. The output spur gear 40 is connected to the actuating arm 14 in a rotationally fixed manner.

[0055] In principle, other energy storage devices 20 can be used, for example, having other means for storing energy instead of a compression spring 21. Likewise, it is not absolutely necessary for a lever 23 to be provided to drive the coupling element 25. The energy storage device 20 can also act directly on the coupling element 25, for example. Other types of gears 18 are also conceivable, such as a lever gear. Furthermore, the gear 18 can also be designed such that the input angle of rotation of the coupling element 25 is greater than the output angle of rotation of the actuating arm 14.
