Description

Technical Field

[0001] This invention relates to a furniture drive device for moving furniture components movably supported relative to a furniture body, particularly for moving furniture flaps pivotable about a horizontal axis relative to the furniture body. The furniture drive device includes:

[0002] —The housing, which may be arranged on or within the furniture panel of the furniture body.

[0003] —At least one adjustable arm movably supported relative to the housing, on which a movable furniture component can be fixed, wherein the housing has an end side, and the at least one adjustable arm protrudes through the end side in at least one relative position.

[0004] —At least one spring device, by means of which force can be applied to the at least one adjusting arm.

[0005] —At least one adjusting device for adjusting the force that can be applied to the at least one adjusting arm by the at least one spring device, and

[0006] —At least one display device, which can display force adjustment that can be performed by means of the at least one adjustment device.

[0007] Furthermore, the present invention relates to a type of furniture having a main body and at least one furniture component movably supported relative to the main body, preferably at least one furniture flap pivotable relative to the main body about a horizontal axis in the furniture's use position. Background Technology

[0008] Such a furniture drive mechanism is known from document DE202010005934U1, in which the force adjustment of the adjusting arm can be read through an opening in the housing. This opening is located on the side of the housing. The force adjustment can be operated via an adjusting device. The furniture drive mechanism is arranged on the inner side of the furniture panel of the furniture body.

[0009] The drawback of existing technology is that when a furniture drive mechanism is used within the furniture panel of the main body of the furniture, the assembler and / or operator of the furniture drive mechanism cannot obtain any information regarding force adjustment. Furthermore, when the force adjustment changes, the assembler and / or operator of the furniture drive mechanism cannot determine or read the changed force adjustment. The adjustment of the force adjustment cannot therefore be guaranteed to a sufficient degree, resulting in reduced comfort during the operation of the furniture drive mechanism and / or the furniture. Consequently, precise adjustment of the force cannot be guaranteed in the installation position of the furniture drive mechanism within the furniture. However, the exposed furniture drive mechanism, positioned outside the furniture panel, reduces the storage space of the furniture and also affects the aesthetic appearance of the main body of the furniture. Summary of the Invention

[0010] Therefore, the objective technical task of the present invention is to provide a furniture drive device that is an improvement over the prior art and a piece of furniture having at least one such furniture drive device, wherein at least partially eliminating the disadvantages of the prior art, and its features are particularly in the precisely determinable force adjustment of the at least one adjusting arm in the mounting position of the furniture drive device in the furniture.

[0011] This task is solved by a furniture drive mechanism for moving furniture components movably supported relative to the furniture body, the furniture drive mechanism comprising:

[0012] —The housing, which can be disposed on the furniture panel of the furniture body or disposed within the furniture panel.

[0013] —At least one adjustable arm movably supported relative to the housing, a movable furniture component can be fixed to the adjustable arm, wherein the housing has an end side through which the at least one adjustable arm protrudes in at least one relative position.

[0014] —At least one spring device, by means of which force can be applied to the at least one adjusting arm.

[0015] —At least one adjusting device for adjusting the force that can be applied to the at least one adjusting arm by the at least one spring device, and

[0016] —At least one display device, which can display force adjustment that can be performed by means of the at least one adjustment device.

[0017] The at least one display device is constructed separately from the at least one adjustment device and the at least one display device is readable in the following installation position of the furniture drive device, in which the housing is completely arranged in the furniture panel of the furniture body except for the end side, wherein the housing includes at least one side facing the interior of the furniture drive device, and at least a portion of the at least one display device is arranged on the at least one side facing the interior of the furniture drive device.

[0018] Therefore, according to the present invention, the at least one display device is constructed separately from the at least one adjustment device and the at least one display device is readable in the following installation position of the furniture drive device, in which the housing is completely arranged in the furniture panel of the furniture body except for the end side.

[0019] This allows the operator and / or assembler to precisely adjust the force adjustment in the installation position of the furniture drive unit, without the need to disassemble and reassemble the furniture drive unit, since the force adjustment can be seen from the line of sight when viewed from the front of the furniture body via the at least one display device.

[0020] As detailed at the beginning, protection is also provided for a type of furniture having a furniture body and at least one furniture component movably supported relative to the furniture body, preferably at least one furniture flap pivotable relative to the furniture body about a horizontal axis in the furniture's use position, wherein the furniture has at least one furniture drive device according to the invention, wherein the furniture body has at least one furniture panel preferably arranged vertically, and the housing of the at least one furniture drive device is arranged on or in the furniture panel, and the at least one furniture component is fixed or can be fixed to the at least one adjusting arm of the at least one furniture drive device.

[0021] The term "separately" can be designed such that the components or groups of components of the display device itself can be identified, which, although spatially connected to the adjustment device indirectly or directly (e.g., material-locked) if necessary, is functionally used for the visualization or reading possibility of force adjustment caused by the adjustment device and therefore does not have a functional interaction with the force adjustment itself.

[0022] According to an advantageous design of the invention, the at least one display device is readable in the mounting position of the furniture drive device, at least in the relative position of the at least one adjusting arm protruding through the end side of the housing.

[0023] This enables the adjustment of the force applied to the at least one adjusting arm by the at least one spring device to be comfortably read from the end side of the housing in the at least one relative position of the at least one adjusting arm. This is crucial for user-friendly force adjustment.

[0024] Advantageously, the at least one display device is arranged at least partially on the area of ​​the at least one adjusting arm, preferably within the at least one adjusting arm, which is arranged outside the housing in a relative position at the end side of the at least one adjusting arm protruding through the housing.

[0025] Advantageously, the at least one adjusting arm has at least one adjusting arm opening, wherein the at least one display device is readable through the at least one adjusting arm opening in a relative position where the at least one adjusting arm protrudes through the end side of the housing.

[0026] By arranging the at least one display device on the at least one adjustment arm, the at least one display device can advantageously extend beyond the end side of the housing in at least one relative position, which simplifies the reading of force adjustment for operators and / or assemblers and / or can improve the aesthetic appearance of the furniture drive mechanism.

[0027] According to an advantageous embodiment of the invention, at least one opening is arranged in the end side of the housing, and the at least one display device is at least partially arranged inside the housing and can be read when looking into the housing through the at least one opening.

[0028] The force adjustment inside the housing can be read through the at least one opening, which ensures a compact furniture drive mechanism.

[0029] Advantageously, the housing has two spaced-apart sides that are substantially parallel to each other and arranged transversely to the end sides of the housing, and the at least one display device is at least partially arranged between or in the net width between the two sides.

[0030] This has the positive effect that the at least one display device is protected from contamination and / or prevents debris when installed in furniture.

[0031] Typically, the at least one display device can also extend into the outer area of ​​the housing through the at least one opening.

[0032] An advantageous variation is that the at least one display device is at least partially arranged on the at least one adjustment device, wherein, preferably, the at least one display device is arranged on the end-facing side of the at least one adjustment device, and particularly preferably, between the end-facing side and the at least one adjustment device.

[0033] The structural design of arranging the at least one display device on the at least one adjustment device makes it particularly advantageous to coordinate the adjustment of the force applied to the at least one adjustment arm by the at least one spring device with the force adjustment to be read by the at least one display device.

[0034] If the at least one display device is positioned between the end side and the at least one adjustment device, force adjustment reading can be achieved through the at least one display device in the line of sight direction inclined to the end side.

[0035] Particularly preferably, the at least one display device includes at least one scale and at least one pointer movable relative to the at least one scale, preferably wherein the at least one scale is engraved into at least one component of the furniture drive device or attached to at least one component of the furniture drive device.

[0036] The operator and / or assembler of the furniture drive unit can discern the degree of force adjustment by observing the relative position of the at least one pointer and the at least one scale.

[0037] If the at least one scale mark is attached, then the at least one scale mark can be updated quickly.

[0038] Typically, the scale can be given, for example, by engraving, drawing, and / or by protrusions in the housing material.

[0039] In one embodiment of the invention, the at least one pointer is movable relative to the at least one scale when adjusting the force that can be applied to the at least one adjusting arm by the at least one spring device, and / or the adjustment of the force that can be applied to the at least one adjusting arm by the relative position of the at least one pointer and the at least one scale is readable.

[0040] If the at least one pointer is moved relative to the at least one scale, especially when force is adjusted by the at least one adjusting device, it is particularly advantageous to transfer the force adjustment to the at least one display device, wherein the operator and / or assembler can identify by observing the at least one display device which force is applied to the at least one adjusting arm by the at least one spring device.

[0041] According to a preferred embodiment of the invention, the at least one scale is arranged on at least one preferably transparent film, wherein, preferably, the housing has at least one housing opening on at least one side that is present if necessary, and the at least one film can be mounted or installed on the housing opening, wherein the scale is arranged on the side of the at least one film facing the at least one adjustment device.

[0042] Utilizing at least one thin film, the at least one scale can be installed on the furniture drive mechanism not only in a space-saving manner but also cost-effectively. If the scale points towards the side facing the adjustment device, the force adjustment of the installation position can be read particularly comfortably through the housing opening.

[0043] In an advantageous variant of the invention, at least one scale is provided on at least one pointer movable relative to the housing, and at least one mark is provided on at least one component of the furniture drive mechanism, wherein the at least one pointer is movable relative to the at least one mark when adjusting a force that can be applied to the at least one adjusting arm by the at least one spring device, and / or the adjustment of the force that can be applied to the at least one adjusting arm by the relative position of the at least one mark and the at least one pointer is readable.

[0044] The markings may be given, for example, by sticking, engraving, drawing, and / or by protrusions on a part of the furniture drive mechanism.

[0045] It has been proven advantageous that the at least one pointer is constructed in the form of a preferably stamped sheet or preferably a wire with a thickened portion.

[0046] If the pointer is constructed of sheet metal, a particularly narrow furniture drive can be provided, where the rigid pointer enables a particularly precise display of force adjustment. If the pointer is constructed of wire, it is particularly advantageous to produce a force adjustment display over longer distances, in complex geometries, and / or in locations where the furniture drive is difficult to access, where the weight of the furniture drive can be kept low.

[0047] The material of the at least one pointer is generally arbitrary. Particularly preferred, the pointer is made of metal or plastic.

[0048] Furthermore, it is preferably specified that the at least one pointer is substantially capable of translational or rotational movement.

[0049] According to an advantageous design of the invention, the at least one adjusting device includes an adjusting mechanism, preferably in the form of a tool receiving portion, wherein the force that can be applied to the at least one adjusting arm by the at least one spring device can be adjusted by the adjusting mechanism.

[0050] The force adjustment can be adjusted, for example, using a commercially available screwdriver and / or Allen wrench, via the at least one adjustment device.

[0051] In another embodiment, the at least one display device includes at least one locking device, wherein the at least one locking device can lock or be locked into at least one receiving device, wherein, preferably, the at least one display device includes a transmission part by which the force that can be applied to the at least one adjusting arm by the at least one adjusting device can be converted by the at least one spring device at a transmission ratio, particularly preferably at a transmission ratio of at least 2:1.

[0052] In this context, the term "lock" should be understood as the arrangement of locking devices within or on receiving devices.

[0053] The at least one locking device can lock into the at least one receiving device when the force adjustment is performed, thereby allowing the at least one pointer to move, in particular, along the at least one scale by rotational motion. This eliminates the need for a separate film on which the scale is arranged, as the at least one scale and the at least one pointer can be arranged on the at least one adjusting device.

[0054] The display device can be designed compactly, especially within a large adjustment range of the force adjustment, thanks to the transmission mechanism.

[0055] According to a preferred embodiment of the invention, the housing includes at least one side, preferably facing the interior of the furniture drive device, wherein at least a portion of the at least one display device is arranged on the at least one side, preferably facing the interior of the furniture drive device.

[0056] According to an advantageous design according to the invention, the at least part of the at least one display device exists in the form of at least one scale and / or at least one mark, wherein, preferably, the at least one display device includes at least one pointer movable relative to the at least one scale and / or the at least one mark, preferably arranged between two sides facing the interior of the furniture drive mechanism.

[0057] By means of the at least one scale and / or markings arranged on the side, the user of the furniture drive can, particularly advantageously (especially in the case of a narrow furniture drive where space is limited), read the force adjustment of the at least one adjustment device from the front of the furniture drive via the at least one display device. This can be achieved, for example, particularly advantageously by means of a pointer arranged between the two sides.

[0058] For example, the at least one scale and / or the at least one mark can be arranged on the side facing the interior of the furniture drive mechanism via a film. Particularly preferably, the scale is arranged on the side facing the exterior of the furniture drive mechanism via a film, wherein the at least one scale is oriented towards the interior of the furniture drive mechanism, and in this context, the interior-facing side is designed so wide that the interior-facing side can, for example, be formed by the metal surface of the housing and the film (see...). Figure 7c ).

[0059] In a manner similar to the scale arranged on the side, the kinematics reverses (kinematischeUmkehr) (see... Figure 5b The embodiment of the above is also possible, wherein the at least one scale is arranged on the at least one pointer arranged between two sides of the housing, wherein the at least one pointer is movable relative to the at least one mark, wherein the at least one mark is arranged on at least one component of the furniture drive and / or on the at least one side, preferably facing the interior of the furniture drive.

[0060] The at least one mark and / or the at least one scale can typically be drawn, pasted, engraved, formed by protrusions, etc.

[0061] Particularly preferred is that the at least one furniture component can move relative to the furniture body via the at least one furniture drive device.

[0062] This enables the opening and / or closing of furniture components, with a particular preference for bidirectional movement of the furniture components relative to the main body of the furniture.

[0063] According to a preferred embodiment of the present invention, the housing of the at least one furniture drive device is entirely disposed within the at least one furniture panel of the furniture body, except for the end side.

[0064] In the prior art, when a furniture drive unit is mounted on furniture, the furniture drive unit is arranged on a furniture panel. Multiple storage spaces and / or more compact and aesthetically pleasing furniture are provided by a furniture drive unit integrated into at least one furniture panel, wherein the relative position of at least one adjusting arm also ensures force adjustment of the furniture drive unit in its mounting position within the at least one furniture panel.

Detailed Implementation

[0085] Figure 1 Furniture 26 with a furniture body 2 is shown, wherein furniture 26 has a furniture drive device 1. Furniture body 2 has a vertically arranged furniture panel 5, and the housing 4 of furniture drive device 1 is arranged in furniture panel 5. Typically, furniture drive device 1 can also be arranged on furniture panel 5.

[0086] The movable furniture component 3 is shown in dashed lines for clarity and will not be shown in the following figures; however, it is typically arranged on the furniture drive unit 1. The furniture component 3 is fixed to the adjusting arm 6 of the furniture drive unit 1 by means of a fixing device. The furniture component 3 is movably supported relative to the furniture body 2 and is configured as a furniture flap that is pivotable relative to the furniture body 2 about a horizontal axis 30 in the use position 27 of the furniture 26.

[0087] Furniture component 3 can move relative to furniture body 2 via furniture drive device 1. The housing 4 of furniture drive device 1, except for the end side 7, is completely arranged in the furniture panel 5 of furniture body 2.

[0088] The number of furniture drive units 1, their position in the furniture panel 5, and the number and / or orientation of the furniture panel 5 are generally arbitrary, and the furniture drive units 1 are arranged on the furniture panel.

[0089] The display device 11, which can be seen in the detailed cross-sectional view, is adjustable by a force applied to the adjusting arm 6 by a spring device 9, allowing for reading from a viewing direction substantially from the front of the furniture 26 or substantially perpendicular to the end side 7. The pointer 18 of the display device 11 is located in relative position 28a. Figures 5a to 1 Section 6 details the components of the furniture drive device 1.

[0090] The display device 11 is constructed separately from the adjustment device 10 and can be read in the mounting position 12 of the furniture drive device 1, in which the housing 4 is completely arranged in the furniture panel 5 of the furniture body 2 except for the end side 7.

[0091] Figure 2 and Figure 1 The only difference is that the pointer 18 of the display device 11 exists in a changed relative position 28b. In the relative position 28b, the adjustment selectable by the force applied to the adjusting arm 6 by the spring device 9 is lower than that in the position 28b. Figure 1 The force in the middle (relative position 28a) is due to the pointer 18 moving further toward the end face 7 relative to the scale 17.

[0092] Typically, the pointer 18 is positioned closer to the relative position 28b on the end face 7; however, it can also indicate increased force adjustment. This can be considered using an inverted scale 17. The relative positions 28a and 28b are not limited for the display device 11, and any number of relative positions 28a and 28b, each with different force adjustments, can be implemented.

[0093] Figure 3 and Figure 2 The only difference is the viewing angle from which the furniture panel 5 is viewed from the opposite side. The display device 11 can be read from both sides in a viewing angle that is tilted relative to the vertical line of the end face 7.

[0094] Figure 4 and Figure 3 The only difference is that pointer 18 is repositioned in the first relative position 28a relative to scale 17.

[0095] Figure 5a A furniture drive device 1 is shown for moving a furniture component 3 that is movably supported relative to a furniture body 2. The furniture drive device includes a housing 4 and an adjusting arm 6. The housing may be arranged on or in the furniture panel 5 of the furniture body 2, and the movable furniture component 3 may be fixed to the adjusting arm.

[0096] The housing 4 has an end side 7 through which the adjusting arm 6 protrudes in a plurality of relative positions 8. The furniture drive mechanism 1 includes: a spring device 9 by which force can be applied to the adjusting arm 6; an adjusting device 10 for adjusting the force that can be applied to the at least one adjusting arm 6 by the spring device 9; and a display device 11 by which the force adjustment that can be performed by means of the adjusting device 10 is displayed. The spring device 9 has coil springs, which are shown in a shortened manner to show the spring retainer on which the coil springs are disposed. Typically, the coil springs, however, extend entirely along the longitudinal extension of the spring retainer.

[0097] Typically, the spring device 9 may also include other accumulators, such as fluid accumulators, and is not limited to the use of helical springs. Above the spring device 9 is a damping device 32 for the movement of the damping adjustment arm 6.

[0098] The display device 11 can be read in the mounting position 12 of the furniture drive device 1 at least in the relative position 8 of the end side 7 of the adjusting arm 6 protruding through the housing 4.

[0099] Figure 5b The pointer 18 is shown, wherein a scale 17 is provided on the pointer 18 which is movable relative to the housing 4, and the pointer 18 moves relative to the mark 21 on the film via the adjusting device 10 when force is adjusted. The display device 11 is located on the adjusting arm 6 in the relative position 28b with a low adjusting force of the spring device 9. The mark 21 can also typically be engraved into the housing 4, drawn on, or formed by protrusions and / or recesses of the housing 4.

[0100] The pointer 18 can move relative to the mark 21 when adjusting the force that can be applied to the adjusting arm 6 by the spring device 9. The adjustment of the force that can be applied to the adjusting arm 6 by the spring device 9 can be read by the relative position 28b of the mark 21 relative to the pointer 18.

[0101] Figure 6a and Figure 5aThe only difference is that the pointer 18, in the form of a stamped sheet 18a, is arranged in another relative position 28a relative to the scale 17, thereby allowing the operator and / or assembler of the furniture drive unit 1 to know the increased force adjustment in a line of sight that is substantially perpendicular to or slightly inclined to the end face 7, especially in the installation position.

[0102] Figure 6b and Figure 6a The only difference is that it shows the inverted kinematics, where, with Figure 6a In contrast, the second relative position 28b shows the same point of action of the spring device 9 on the lever mechanism connected to the adjusting arm 6.

[0103] Figure 7a and Figure 7b A furniture drive unit 1 with a complete housing 4 is shown, and the installation of the furniture drive unit 1 in the mounting position 12 in the furniture 26 via the housing is particularly preferred.

[0104] An opening 14 is provided in the end side 7 of the housing 4, and the display device 11 is partially arranged inside the housing 4, because the pointer 18 in the form of a plate 18a is completely arranged inside the housing 4 and the two scales 17 are respectively mounted on the housing 4 from the outside through a thin film 19. The display device 11 can be read when looking into the interior of the housing 4 through the opening 14. The display device 11 can also typically be completely arranged inside the housing 4.

[0105] The housing 4 has two spaced-apart sides 15, which are parallel to each other and arranged transversely to the end sides 7 of the housing 4. The display device 11 is partially arranged between the two sides 15. Typically, the display device 11 may also be arranged entirely within or in the middle of the net width 16 of the sides 15.

[0106] The display device 11 is partially arranged on the adjustment device 10, wherein the display device 11 is arranged on the side of the adjustment device 10 facing the end side 7 and is arranged between the end side 7 and the at least one adjustment device 10.

[0107] exist Figure 7a In this case, the film 19 is opaque and is fixed to the housing 4 by a fixing device. Figure 7b In this case, the graduations 17 are partially adhered from the outside to two sides 15 of the housing 4 through two housing openings 20 on a transparent film 19 made of plastic. The graduations 17 are arranged on the side of the film 19 facing the adjustment device 10. Particularly preferably, the film 19 made of plastic is adhered from the outside to at least one side 15, wherein the graduations 17 are provided on the adhesive side of the film 19.

[0108] Figure 7cThe display device 11 is shown, wherein a scale 17 is provided on one of the two sides 15, and the second housing opening 20 is at least partially not covered by the film 19. The scale 17 is provided on the adhesive side of the film 19, wherein the area of ​​the film on which the scale 17 is arranged is configured to be free of adhesive.

[0109] Typically, the nature, quantity, and positioning of the film 19 are arbitrary. It has proven particularly advantageous to have two opaque plastic films that are adhered from the outside to the two housing openings 20 on both sides, with the scale 17 positioned on the adhesive side.

[0110] Figure 8a A furniture drive unit 1 is shown, which has a display device 11 with two pointers 18 positioned between the sides 15. The pointers, through the relative position between two films 19 (which are partially arranged on two housing openings 20), allow the operator to display from the outside, in the viewing direction of the end face 7 of the furniture drive unit 1, the force of the adjustment arm 6 adjusted by the spring device 9.

[0111] Figure 8b and Figure 8c Shown in the second relative position 28b Figure 8a The second relative position 28b shows a changed force adjustment, which has a reduced force loading on the adjusting arm 6 via the spring device 9.

[0112] exist Figure 8b In this configuration, the pointer 18 is constructed as a stamped sheet metal 18a that is bent in the connection area with the adjustment device. Typically, the pointer 18 may also be made of, for example, injection-molded plastic. The pointer 18 can translate in a direction perpendicular to the movement direction of the end side 7.

[0113] exist Figure 8c The positions of the components involved in the display device 11 and covered by the film 19 are shown in dashed lines.

[0114] The display device 11 includes two scales 17 and two pointers 18 that are movable relative to them, wherein the two scales 17 are attached to the housing 4. Typically, the scales 17 may also be engraved into a part of the furniture drive device 1.

[0115] The pointer 18 can move relative to the scale 17 when adjusting the force that can be applied to the adjusting arm 6 by the spring device 9, and the adjustment of the force that can be applied to the adjusting arm 6 by the spring device 9 can be read from both sides of the end side 7 by the relative positions 28a, 28b of the pointer 18 relative to the scale 17.

[0116] Figure 9A furniture drive device 1 with a display device 11 is shown, wherein the display device 11 includes a plurality of locking devices 24, wherein the locking devices 24 can be locked into a plurality of receiving devices 25. The display device 11 has a transmission section 29, through which the force that can be applied to the adjustment arm 6 by the spring device 9 can be adjusted by the adjustment device 10 at a transmission ratio.

[0117] The display device 11 has a scale 17 arranged on an arc section, wherein the transmission part 29 and the pointer are rotatably constructed in a plane parallel to the end side 7 by means of the adjustment device when the force of the adjustment arm 6 is adjusted.

[0118] In order to adjust the force adjustment, the adjustment device 10 has an adjustment device 23 in the form of a tool receiving part 23a, wherein the adjustment device 23 can be used to set the adjustment of the force that can be applied to the adjustment arm 6 by the spring device 9.

[0119] Figure 10a A view perpendicular to end side 7 is shown according to Figure 9 The furniture drive mechanism has two assembled sides 15. The pointer 18 is arranged relative to the scale 17 such that the relative position 28b is displayed with minimal force applied to the adjusting arm 6 by the spring device 9.

[0120] Figure 10b and Figure 10a The only difference is that the display device 11 exists in the changed relative position 28a, in which the operator of the furniture drive device 1 can read the force adjustment of the lifting arm 6 through a line of sight perpendicular to the end side 7.

[0121] Figure 11 and Figure 9 The only difference is that the display device 11 exists in the relative position 28a. Since the point of action of the spring device 9 on the lever mechanism kinematically coupled with the adjusting arm 6 remains unchanged, there is, for example, a modified movable furniture part 3 with reduced mass. Therefore, the operator or assembler of the furniture drive device 1 can estimate the force required to move the movable furniture part 3 with the aid of the furniture drive device 1.

[0122] The spring device 9 has a shortened helical spring in the diagram so that the spring housing is visible, on which the helical spring is arranged; however, the helical spring typically extends over the entire longitudinal extension of the spring housing.

[0123] Figure 12 and Figure 11The difference lies only in that the force adjustment is achieved by adjusting the device 10, wherein the point of action of the spring device 9 moves downward, and the force adjustment is achieved by adjusting the device, and the display device 11 is present in the relative position 28b to show the operator the changed force consumption for moving the movable furniture part 3.

[0124] The point of action of the spring device 9 on the lever mechanism of the adjusting arm 6 can be adjusted by the adjusting device 10 and is coupled to the force adjustment and display via the display device. The change in force adjustment by the adjusting device 10 changes the torque acting on the adjusting arm 6, thereby changing the force acting on the movable furniture part 3.

[0125] On the furniture drive device 1, a fixing device 31 for fixing the housing 4 is arranged in the recess of the furniture body 2.

[0126] The fixing device 31 includes a rotatably supported operating element and two fixing elements that can descend into the wall of the recess and / or be pressed against the wall. A coupling device is provided in the fixing device 31, which converts the rotational movement of the operating element into the descending movement and / or pressing movement of the two fixing elements. The operating element and the two fixing elements are arranged on the same side of the housing 4 and spaced apart from each other in the longitudinal direction of the housing 4. The number of fixing elements is generally arbitrary.

[0127] Figure 13a A furniture drive unit 1 with an adjustment device 10 is shown, wherein the display device 11 has not yet been assembled.

[0128] Figure 13b and Figure 13c A furniture drive unit 1 is shown, which has a display device 11 mounted in two different relative positions 28a, 28b. A pointer 18 exists in the form of a disc with a receiving device 25. The rotation of the pointer 18 is caused by the interaction between the receiving device 25 and the locking device 24 of the display device.

[0129] and Figure 9 In contrast, a modified transmission unit 29 is fitted. The transmission ratio between the force adjustment via the tool receiving part 23a and the display on the scale 17 via the pointer 18 is generally arbitrary. A transmission ratio of at least 2:1 has proven to be particularly advantageous.

[0130] The pointer 18 is materially locked to the transmission part 29.

[0131] Figure 14aA furniture drive unit 1 is shown, wherein a display device 11 is at least partially arranged in an area within an adjusting arm 6. The adjusting arm 6 is arranged outside the housing 4 at a relative position 8 where the adjusting arm 6 protrudes through the end side 7 of the housing 4. The side 15 of the housing 4 is removed for clarity.

[0132] As can be seen in the detailed view of the adjusting arm 6, the adjusting arm 6 has an adjusting arm opening 13, in which the display device 11, in a relative position 8 (in which the adjusting arm 6 protrudes through the end side 7 of the housing 4), can be read through the adjusting arm opening 13. The adjusting arm opening 13 is arranged on both sides of the adjusting arm 6, thereby allowing for force adjustment by reading the display device 11 on both sides of the adjusting arm 6, and is particularly advantageous for use in the corners of the space within the furniture 26.

[0133] The pointer 18, in the form of wire 18b, has a thickened portion 22 at its free end, wherein the pointer is arranged in a first relative position 28a.

[0134] Figure 14b and Figure 14a The only difference is that the adjusting arm opening 13 is located on the lower side of the adjusting arm 6, wherein... Figure 14a The opening 13 of the adjusting arm continuously guides through both sides of the adjusting arm 6. Typically, the opening 13 of the adjusting arm can also be arranged on only one side of the adjusting arm 6 or on both sides and the underside, so as to display the force adjustment to the operator via the display device 11.

[0135] Typically, another display device 11 may be provided, wherein, for example, a pointer 18 is arranged on the adjustment device 10 and / or a scale 17 is arranged at the housing opening 20.

[0136] Figure 14c A detailed portion of the display device 11 is shown in another relative position 28b, wherein the force adjustment relative to the [other position] is changed by the adjustment device 10. Figure 14a The relative position 28a is shown in the figure.

[0137] Figure 15a The furniture drive mechanism is shown, wherein the adjustment arm opening 13 is arranged on the underside of the adjustment arm 6, thereby ensuring that the force adjustment via the display device 11 is particularly comfortable to read by the operator and / or assembler, especially when the furniture drive mechanism 1 is arranged high on the furniture 26.

[0138] Typically, however, an adjustment arm opening 13 may be arranged on the upper side of the adjustment arm 6, so that a more user-friendly decision regarding the force adjustment can be made, especially when the furniture drive unit 1 is deeply positioned on the furniture 26.

[0139] In the magnified details, it can be seen that the thickened part 22 of the display device 11 shows the increased force acting on the adjusting arm 6 by the pointer 18 being closer to the relative position 28a of the plus sign positioning.

[0140] Figure 15b and Figure 15a The only difference in the details is that the pointer 18 is arranged in another relative position 28b at the opening 13 of the adjusting arm, and in order to simplify force adjustment, an additional scale 17 is arranged on the lower side of the adjusting arm 6.

[0141] The pointer 18 exists in the form of a wire 18b with a thickened portion 22. Typically, the wire 18b may include, for example, a Bowden cable.

[0142] Figure 16a A furniture drive device 1 is shown, which has an adjusting arm 6 supported around a rotation axis for moving a movable furniture part 3, a spring device 9 arranged on a spring retainer for applying force to the adjusting arm 6, and a transmission mechanism in the form of a lever mechanism for transmitting force from the spring device 9 to the adjusting arm 6, wherein the transmission mechanism is arranged on the spring device 9 via a point of action.

[0143] The point of action can be adjusted by an adjustment device 10 for adjusting the position of the point of action, wherein when the point of action changes, a changed torque (not shown for clarity) for moving the movable furniture part 3 is applied to the adjustment arm 6.

[0144] The adjustment device 10 is complete, with the transmission mechanism and adjustment arm 6 partially arranged within the housing 4. A display device 11 is provided separately from the adjustment device 10, wherein the force adjustment of the adjustment arm 6 can be read by the display device 11 at the position of the point of action of the spring device 9.

[0145] Scale 17 is located on the underside of the adjusting arm 6 (not visible in this diagram). Scale 17 may also be omitted, wherein the force adjustment of the adjusting arm 6 is indicated by the relative positioning of the pointer 18 with respect to the adjusting arm 6 or by the adjusting arm opening 13 located on the underside of the adjusting arm 6, wherein the pointer 18 is visible through the adjusting arm opening 13.

[0146] The display device 11 includes a pointer 18 partially arranged within the adjustment arm 6.

[0147] Figure 16b Showing according to Figure 16a The furniture drive device 1, in addition to the pointer 18 arranged on the adjustment device 10, has a thin film 19 with scale 17 arranged on the housing 4 so as to provide the operator and / or assembler of the furniture drive device 1 with a more comfortable display of force adjustment by another display device 11.

[0148] Figure 16c Showing according to Figure 16a The furniture drive device 1 does not have a pointer 18 arranged on the adjustment device 10, wherein the force adjustment is displayed only by a display device 11 arranged on the adjustment arm 6.
