The invention relates to a furniture drive for moving a furniture part that is mounted movably relative to a furniture body, in particular a furniture flap that is pivotable about a horizontal axis relative to the furniture body. The furniture flap includes:
Furthermore, the invention relates to a piece of furniture with a furniture body and at least one furniture part mounted movably relative to the furniture body, preferably at least one furniture flap that is pivotable about a horizontal axis relative to the furniture body in a position of use of the piece of furniture.
Such a furniture drive is already known from the specification DE 20 2010 005 934 U1, in which a force adjustment of an actuating arm can be read via an opening in a housing. Here, the opening is arranged on a side face of the housing. The force adjustment can be manipulated via an adjusting device. The furniture drive is arranged on an inside of a furniture panel of a furniture body of a piece of furniture.
A disadvantage of the state of the art is that an installer and/or operator of the furniture drive cannot generate any information at all about a force adjustment when using the furniture drive inside the furniture panel of the furniture body. Furthermore, it is not possible for the installer and/or operator of the furniture drive to determine or rather read the altered force adjustment when the force adjustment is altered. An adjustment of the force adjustment cannot thereby be guaranteed to a sufficient degree, which results in reduced convenience in operating the furniture drive and/or the piece of furniture. A precise adjustment of the force adjustment is thereby not guaranteed in an installed position of the furniture drive in the piece of furniture. However, locating a furniture drive exposed, outside of the furniture panel, on the one hand reduces the storage space of the piece of furniture and on the other hand impairs the aesthetic appearance of the furniture body.
The objective technical problem of the present invention is therefore to specify a furniture drive that is improved compared with the state of the art and a piece of furniture with at least one such furniture drive, in which the disadvantages of the state of the art are at least partially rectified, and which are characterized in particular by a precise, determinable force adjustment of the at least one actuating arm in an installed position of the furniture drive in the piece of furniture.
Thus, according to the invention, the at least one display device is formed separately from the at least one adjusting device and can be read in an installed position of the furniture drive, in which the housing is arranged completely, except for the end face, in the furniture panel of the furniture body.
It is thereby made possible for the first time for an operator and/or installer to be able to adjust the force adjustment precisely in the installed position of the furniture drive, wherein it is not necessary to dismantle and re-assemble the furniture drive, since the force adjustment is visible via the at least one display device from a viewing direction from the front onto the furniture body.
As stated at the beginning, protection is also sought for a piece of furniture with a furniture body and at least one furniture part that is mounted movably relative to the furniture body, preferably at least one furniture flap that is pivotable about a horizontal axis relative to the furniture body in a position of use of the piece of furniture. The piece of furniture has at least one such furniture drive, and the furniture body has at least one, preferably vertically arranged, furniture panel and the housing of the at least one furniture drive is arranged on or in the furniture panel. The at least one furniture part is fastened or can be fastened on the at least one actuating arm of the at least one furniture drive.
The term “separately” is to be interpreted such that a distinct display device component or component assembly can be identified which, although in spatial terms, can possibly be connected indirectly or directly (such as in a material-bonding manner) to the adjusting device, in functional terms the display device serves for the visualization or rather read capability of the force adjustment brought about by the adjusting device and thus has no functional interaction with the force adjustment per se.
According to an advantageous design of the invention, the at least one display device can be read in the installed position of the furniture drive at least in the relative position in which the at least one actuating arm protrudes through the end face of the housing.
It is thereby made possible for the adjustment of the force that can be exerted on the at least one actuating arm by the at least one spring device, in the at least one relative position of the at least one actuating arm, to be readable conveniently via the end face of the housing. This is of vital importance for a user-friendly adjustment of the force adjustment.
Advantageously, the at least one display device can be arranged at least partially on a region of the at least one actuating arm, preferably within the at least one actuating arm, which is arranged outside the housing in the relative position in which the at least one actuating arm protrudes through the end face of the housing.
It has proved to be advantageous for the at least one actuating arm to have at least one actuating arm opening, wherein the at least one display device can be read through the at least one actuating arm opening in the relative position in which the at least one actuating arm protrudes through the end face of the housing.
Through an arrangement of the at least one display device on the at least one actuating arm, the at least one display device can particularly advantageously protrude beyond the end face of the housing in at least one relative position, wherein it is made easier for the force adjustment to be read by an operator and/or installer and/or an aesthetic appearance of the furniture drive can be improved.
According to an advantageous embodiment of the invention, at least one opening is arranged in the end face of the housing and the at least one display device is arranged in the interior of the housing at least in regions and can be read by looking through the at least one opening into the interior of the housing.
Reading the force adjustment in the interior of the housing is made possible through the at least one opening, wherein a compact furniture drive can be guaranteed.
It has proved to be advantageous for the housing to have two side faces spaced apart from one another, which are arranged substantially parallel to one another and in each case transversely relative to the end face of the housing, and wherein the at least one display device is arranged between or in a clear width between the two side faces at least in regions.
This has the positive effect that the at least one display device is protected from dirt and/or from shavings during an installation in a piece of furniture.
In general, the at least one display device can, however, also protrude through the at least one opening into an outer region of the housing.
An advantageous variant consists of the at least one display device being arranged at least partially on the at least one adjusting device, wherein it is preferably provided that the at least one display device is arranged on a side of the at least one adjusting device facing the end face, particularly preferably between the end face and the at least one adjusting device.
The constructive design of an arrangement of the at least one display device on the at least one adjusting device particularly promotes a coupling of the adjustment of the force, which can be exerted on the at least one actuating arm by the at least one spring device, with the force adjustment to be read via the at least one display device.
If the at least one display device is located between the end face and the at least one adjusting device, reading the force adjustment via the at least one display device in the case of a viewing direction obliquely in relation to the end face is made possible.
It is particularly preferred for the at least one display device to comprise at least one scale and at least one indicator that is movable relative thereto, preferably wherein the at least one scale is engraved into at least one part of the furniture drive or is glued onto at least one part of the furniture drive.
An operator and/or installer of the furniture drive can see a size of the force adjustment from a position of the at least one indicator relative to the at least one scale.
If the at least one scale is glued on, the at least one scale can be quickly renewed.
In general, the scale can also, for example, be carved into, painted on and/or provided by embossments in the material of the housing.
In an embodiment of the invention, the at least one indicator is movable relative to the at least one scale when the force that can be exerted on the at least one actuating arm by the at least one spring device is adjusted and/or the adjustment of the force that can be exerted on the at least one actuating arm by the at least one spring device can be read from a position of the at least one indicator relative to the at least one scale.
If, through a force adjustment, in particular in the case of a force adjustment via the at least one adjusting device, the at least one indicator is moved relative to the at least one scale, a transmission of the adjustment of the force onto the at least one display device is made possible in a particularly advantageous manner, wherein an operator and/or installer can see by looking at the at least one display device what force is applied to the at least one actuating arm by the at least one spring device.
According to a preferred embodiment of the invention, the at least one scale is arranged on at least one, preferably transparent, film, and preferably the housing has at least one housing opening, preferably on at least one possibly present side face, to which the at least one film can be affixed or is affixed, wherein the scale is arranged on a side of the at least one film facing the at least one adjusting device.
With at least one film, the at least one scale can be affixed to the furniture drive both in a space-saving manner and cost-effectively. If the scale faces in the direction of the side facing the adjusting device, in the installed position the force adjustment can be read particularly conveniently by looking through the housing opening.
In an advantageous variant of the invention, at least one scale is arranged on at least one indicator that is movable relative to the housing and at least one marking is provided on at least one part of the furniture drive. The at least one indicator is movable relative to the at least one marking when the force that can be exerted on the at least one actuating arm by the at least one spring device is adjusted and/or the adjustment of the force that can be exerted on the at least one actuating arm by the at least one spring device can be read from a position of the at least one marking relative to the at least one indicator.
The marking can, for example, be glued on, engraved in, painted on and/or provided by embossments in a part of the furniture drive.
It has proved to be advantageous for the at least one indicator to be in the form of a preferably punched metal sheet or a wire, preferably with a thickening.
If the indicator is formed as a metal sheet, a particularly narrow furniture drive can be provided, wherein a rigid indicator makes a particularly precise display of the force adjustment possible. If the indicator is formed as a wire, a display of the force adjustment can be generated particularly advantageously over long distances, complex geometries and/or in positions of the furniture drive that are difficult to access, wherein a weight of the furniture drive can be kept low.
The material of the at least one indicator is generally as desired. The indicator is particularly preferably formed of metal or plastic.
Furthermore, preferably the at least one indicator is substantially movable in a translational manner or rotatable.
According to an advantageous design of the invention, the at least one adjusting device comprises a readjusting device, preferably in the form of a tool holder, wherein the adjustment of the force that can be exerted on the at least one actuating arm by the at least one spring device is adjustable via the readjusting device.
Through the at least one adjusting device, the force adjustment can be adjusted using a commercially available screwdriver and/or Allen key, for example.
In a further embodiment, the at least one display device comprises at least one catching means, wherein the at least one catching means can catch or is caught in at least one receiving means. Preferably, the at least one display device comprises a transmission via which an adjustment of the force that can be exerted on the at least one actuating arm by the at least one spring device by means of the at least one adjusting device can be transmitted with a transmission ratio, particularly preferably with a transmission ratio of at least 2:1.
By the term “to catch” is meant in this context an arrangement of the catching means in or on the receiving means.
In the case of an adjustment of the force adjustment, the at least one catching means can catch in the at least one receiving means, as a result of which the at least one indicator can be moved, in particular by a rotational movement, along the at least one scale. A separate film, on which the scale is arranged, is thereby not needed as the at least one scale and the at least one indicator can be arranged on the at least one adjusting device.
Through a transmission, the display device can be designed compactly, in particular in the case of large adjustment ranges of the force adjustment.
According to a preferred embodiment of the invention, the housing comprises at least one side face, preferably turned towards the interior of the furniture drive. At least one part of the at least one display device is arranged on the at least one side face that is preferably turned towards the interior of the furniture drive.
According to an advantageous design of the invention, the at least one part of the at least one display device is present in the form of at least one scale and/or at least one marking.
Preferably, the at least one display device comprises at least one indicator that is movable relative to the at least one scale and/or the at least one marking, and is preferably arranged between two side faces that are turned towards the interior of the furniture drive.
Because of the arrangement of the at least one scale and/or marking on the side face, a user of the furniture drive can read the force adjustment of the at least one adjusting device via the at least one display device particularly advantageously from the front side of the furniture drive because of a larger viewing angle (which is limited in particular in the case of narrow furniture drives). This can be realized particularly advantageously, for example via an indicator arranged between two side faces.
For example, the at least one scale and/or the at least one marking can be arranged via a film on the side face that is turned towards the interior of the furniture drive. Particularly preferably, the scale is arranged via a film on the side face that is turned towards the exterior of the furniture drive. The at least one scale is oriented in the direction of the interior of the furniture drive—in this context, the side face that is turned towards the interior is to be designed so wide that the side face that is turned towards the interior can be formed, for example, by a metal surface of the housing and the film (cf.
Analogously to a scale arranged on the side face, the kinematically inverse embodiment is also possible (cf.
The at least one marking and/or the at least one scale can generally be painted on, glued on, engraved in or formed by embossments etc.
It is particularly preferred that the at least one furniture part is movable relative to the furniture body by the at least one furniture drive.
This makes an opening and/or closing of the furniture part possible, wherein in particular a bidirectional movement of the furniture part relative to the furniture body is particularly preferred.
According to a preferred embodiment example of the invention, the housing of the at least one furniture drive is arranged completely, except for the end face, in the at least one furniture panel of the furniture body.
In the state of the art, the furniture drive is arranged on the furniture panel during the installation of the furniture drive on the piece of furniture. More storage space and/or a more compact and more aesthetic piece of furniture is provided by furniture drives integrated into the at least one furniture panel, wherein reading the force adjustment even in the installed position of the furniture drives within the at least one furniture panel is guaranteed in at least one relative position of the at least one actuating arm.
Further details and advantages of the present invention are explained in more detail below by means of the description of the figures with reference to the embodiment examples represented in the drawings. There are shown in:
For reasons of clarity, a movable furniture part 3 is indicated in dashed lines and does not appear in the following figures; however, it is generally arranged on the furniture drive 1. The furniture part 3 is fastened on the actuating arm 6 of the furniture drive 1 via fastening means. The furniture part 3 is mounted movably relative to the furniture body 2 and formed as a furniture flap that is pivotable about a horizontal axis 30 relative to the furniture body 2 in a position of use 27 of the piece of furniture 26.
The furniture part 3 is movable relative to the furniture body 2 by the furniture drive 1. The housing 4 of the furniture drive 1 is arranged completely, except for the end face 7, in the furniture panel 5 of the furniture body 2.
The number of furniture drives 1, the position in the furniture panel 5 and the number and/or orientation of the furniture panels 5 on which the furniture drives 1 are arranged are generally as desired.
In the detail section, a display device 11 can be seen which makes it possible to read a force adjustment of the force that can be exerted on an actuating arm 6 by a spring device 9, with the viewing direction substantially from the front onto the piece of furniture 26 or rather substantially normal to the end face 7. An indicator 18 of the display device 11 is present in a relative position 28a. The components of the furniture drive 1 are explained in more detail in
The display device 11 is formed separately from the adjusting device 10 and can be read in an installed position 12 of the furniture drive 1, in which the housing 4 is arranged completely, except for the end face 7, in the furniture panel 5 of the furniture body 2.
In general, however, any relative position 28b in which the indicator 18 is located closer to the end face 7 can display an increased force adjustment. An inverted scale 17 can take this situation into account. The relative positions 28a, 28b do not limit the display device 11, wherein any number of relative positions 28a, 28b is possible each with different force adjustments.
The housing 4 has an end face 7, through which the actuating arm 6 protrudes in a plurality of relative positions 8. The furniture drive 1 has a spring device 9, with which a force can be exerted on the actuating arm 6, an adjusting device 10 for adjusting the force that can be exerted on the at least one actuating arm 6 by the spring device 9, and the display device 11, with which a force adjustment that can be carried out by means of the adjusting device 10 is displayed. The spring device 9 has spiral springs, which are represented shortened in order to see the spring holders on which the spiral springs are arranged. However, in general, the spiral springs extend fully over the longitudinal extension of the spring holders.
However, in general, the spring device 9 can also comprise other types of energy store, such as fluid energy stores, and is not limited to the use of spiral springs. A damper device 32 for damping a movement of the actuating arm 6 is arranged above the spring device 9.
The display device 11 can be read in the installed position 12 of the furniture drive 1, at least in the relative position 8 in which the actuating arm 6 protrudes through the end face 7 of the housing 4.
The indicator 18 is movable relative to the markings 21 when the force that can be exerted on the actuating arm 6 by the spring device 9 is adjusted. The adjustment of the force that can be exerted on the actuating arm 6 by the spring device 9 can be read from a position 28b of the markings 21 relative to the indicator 18.
An opening 14 is arranged in the end face 7 of the housing 4 and the display device 11 is arranged in the interior of the housing 4 in regions, since the indicator 18 in the form of a metal sheet 18a is arranged completely inside the housing 4 and two scales 17 have been affixed to the housing 4 from the outside in each case via a film 19. The display device 11 can be read when looking through the opening 14 into the interior of the housing 4. The display device 11 can generally also be arranged completely inside the housing 4.
The housing 4 has two side faces 15 spaced apart from one another, which are arranged parallel to one another and in each case transversely relative to the end face 7 of the housing 4. The display device 11 is arranged between the two side faces 15 in regions. In general, the display device 11 can also be arranged completely between or in a clear width 16 of the side faces 15.
The display device 11 is arranged partially on the adjusting device 10, wherein the display device 11 is arranged on a side of the adjusting device 10 facing the end face 7 and between the end face 7 and the at least one adjusting device 10.
In
In general, the nature, number and positioning of the films 19 is as desired. Two non-transparent plastic films, which are glued on both sides from the outside above two housing openings 20, have proved to be particularly advantageous and the scale 17 is located on the adhesive side.
In
In
The display device 11 comprises two scales 17 and two indicators 18 that are movable relative thereto, wherein the two scales 17 are glued onto the housing 4. In general, the scales 17 can also be engraved into a part of the furniture drive 1.
The indicators 18 are movable relative to the scales 17 when the force that can be exerted on the actuating arm 6 by the spring device 9 is adjusted and the adjustment of the force that can be exerted on the actuating arm 6 by the spring device 9 can be read from the positions 28a, 28b of the indicators 18 relative to the scales 17 from both sides of the end face 7.
The display device 11 has a scale 17 arranged on a segment of a circle, wherein the transmission 29 and an indicator is formed rotatable in a plane parallel to the end face 7 in the case of a force adjustment of the actuating arm 6 by the adjusting device.
In order to adjust the force adjustment, the adjusting device 10 has a readjusting device 23 in the form of a tool holder 23a, wherein the adjustment of the force that can be exerted on the actuating arm 6 by the spring device 9 is adjustable via the readjusting device 23.
In the representation, the spring device 9 has shortened spiral springs, in order to make the spring supports, on which the spiral springs are arranged, visible; however, the spiral springs generally extend over the entire longitudinal extension of the spring supports.
The point of contact of the spring device 9 on the lever system of the actuating arm 6 can be adjusted via the adjusting device 10 and is coupled to the force adjustment and to the display via the display device. Through an alteration of the force adjustment via the adjusting device 10, an altered torque acts on the actuating arm 6, as a result of which the force acting on the movable furniture part 3 is altered.
A fastening device 31 for fastening the housing 4 in a recess of the furniture body 2 is arranged on the furniture drive 1.
The fastening device 31 comprises a rotatably mounted actuating element and two fastening elements that can be countersunk in a wall of the recess and/or pressed onto the wall. A coupling device is provided in the case of the fastening device 31 with which a rotational movement of the actuating element can be converted into a countersinking movement and/or into a pressing-on movement of the two fastening elements. The actuating element and the two fastening elements are arranged on the same side of the housing 4 and spaced apart from one another in a longitudinal direction of the housing 4. The number of fastening elements is generally as desired.
Compared with
The indicator 18 is connected to the transmission 29 in a material-bonding manner.
In a detail view of the actuating arm 6, it can be seen that the actuating arm 6 has an actuating arm opening 13, wherein the display device 11 can be read through the actuating arm opening 13 in the relative position 8 in which the actuating arm 6 protrudes through the end face 7 of the housing 4. The actuating arm opening 13 is arranged on both side faces of the actuating arm 6, as a result of which the force adjustment can be read via the display device 11 on both sides of the actuating arm 6 and can be used particularly advantageously in the case of pieces of furniture 26 in corners of a room.
The indicator 18 in the form of a wire 18b has a thickening 22 on a free end, wherein the indicator is arranged in a first relative position 28a.
In general, a further display device 11 can be provided, wherein, for example, on the adjusting device 10, indicator 18 and/or a scale 17 is arranged on the housing opening 20.
In general, however, an actuating arm opening 13 can also be arranged on an upper side of the actuating arm 6, in order, in particular in the case of furniture drives 1 located deep in the piece of furniture 26, to make it possible to determine the force adjustment in a user-friendly manner.
In the enlarged detail section it can be seen that the thickening 22 of the display device 11 displays an increased force acting on the actuating arm 6 through the spring device 9 through the relative position 28a, in which the indicator 18 is located closer to a plus sign.
The indicator 18 is present in the form of a wire 18b with a thickening 22. In general, the wire 18b can comprise a Bowden cable, for example.
The point of contact is adjustable via an adjusting device 10 for adjusting the position of the point of contact, wherein in the case of an altered point of contact, an altered torque acts on the actuating arm 6 for moving the movable furniture part 3 (not represented for reasons of clarity).
The adjusting device 10 is arranged completely inside the housing 4, the transmission mechanism and the actuating arm 6 are arranged in it in regions. A display device 11 that is separate from the adjusting device 10 is provided, wherein the force adjustment of the actuating arm 6 via the position of the point of contact of the spring device 9 can be read via the display device 11.
A scale 17 is arranged on the underside of the actuating arm 6 (not visible in the representation). In general, the scale 17 can also be dispensed with, wherein the force adjustment of the actuating arm 6 is displayed by a relative positioning of the indicator 18 in relation to the actuating arm 6 or the actuating arm opening 13 located on the underside of the actuating arm 6, wherein the indicator 18 is visible through the actuating arm opening 13.
The display device 11 comprises an indicator 18 arranged within the actuating arm 6 in regions.
