Description

description

The invention relates to an actuator drive for moving a movable furniture part,

full

- At least one actuating arm mounted about an axis of rotation for moving the movable furniture part,

- At least one energy storage device for applying force to the actuating arm,

- A transmission mechanism for transmitting a force from the at least one energy storage device to the actuating arm.

Furthermore, the invention relates to a piece of furniture with a furniture body, at least one movable furniture part, in particular a furniture flap, and at least one, in particular exactly two, such actuating arm drive, which is movably mounted relative to the furniture body, in particular about a horizontal axis. Finally, the invention relates to a set of at least two such actuating arm drives.

An actuator drive is already known from EP 2 678 505 B1, in which an adjusting device with an adjusting screw is provided in order to simplify the adjustment of the spring force of the spring device.

The disadvantage of the prior art is that the spring device must already be matched to the conditions on site and only conditionally an adaptation of the spring force is possible through the adjustment device, since excessive modifications of the spring force exceed the load limits of the spring and / or the Restrict the function of the actuating arm. Before assembly, it must therefore be known which forces will act on the spring in order to adapt it to these specific conditions. A spring with suitable spring force must also be present and installed in the assembly of the actuator drive itself. Furthermore, a separate locking device is necessary for the safe operation of the actuating arm without changing the position of the adjusting screw over time, which harbors the risk of reducing the service life in the event of changing loads.

The objectively technical object of the present invention is therefore to provide an actuating arm drive which is improved over the prior art, in which the disadvantages of the prior art are at least partially eliminated, and which is in particular due to a flexible and comfortable spring force adjustment to changing requirements on the actuating arm, in order to be able to deal with the actually prevailing force relationships with little effort, both in the event of changed conditions of the furniture flap, on site during the assembly of the actuating arm drive and during the assembly of the actuating arm drive.

This object is achieved by the features of claim 1.

It is therefore provided according to the invention that the at least one energy storage device has at least two, preferably more than three, receptacles for at least one energy storage device, each of the at least two receptacles depending on a predetermined force to be provided by the at least one energy storage device optionally with an energy storage device can be equipped.

This only makes it possible that shortly before the assembly of the actuator arm drive can be done quickly and reliably commissioning by the optimal number of energy storage on the size of the furniture flap or the weight to be moved per actuator arm drive. A suitable fitting of the actuating arm drive with energy stores is also facilitated in the use position when the actuating arm drive is mounted on the piece of furniture.

Furthermore, it is advantageous that several energy storage devices can be accommodated by the at least two receptacles, which replace a single energy storage device of larger dimensions. This results in a compact and / or flat design of the actuating arm drive, which can also be integrated, for example, in the side walls of a furniture body, benefiting from the small dimensions required for the actuating arm drive. External fastening elements within the furniture body are avoided and a visually appealing

des and simple furniture with actuator drives guaranteed.

For larger loads, the at least two recordings can be equipped with more energy storage and with low loads recordings can remain empty or be emptied. In addition, there is the positive property that the user or the fitter only needs one type of energy storage device for this, with a different number of energy storage devices being placed in the at least two receptacles depending on the weight of the parts to be moved.

The number of energy storage devices to be used is essentially arbitrary. This can be adapted to the properties of the at least one energy store, whereby the at least one energy store should not be too small in order to enlarge the dimension of the actuator drive too much and not be too large in order to still have a reasonable scope for flexible use of the at least to ensure two shots.

As stated at the beginning, protection is also sought after for a piece of furniture with a furniture body, at least one furniture part, in particular a furniture flap, and at least one, preferably exactly two, such actuating arm drive, which is movably mounted relative to the furniture body, preferably about a horizontal axis the first actuating arm drive part of the at least one actuating arm drive is attached to the furniture body and the second actuating arm drive part of the at least one actuating arm drive is attached to the movably mounted furniture part.

As stated at the outset, protection is also sought after for a set of at least two such actuating arm drives, the at least two actuating arm drives having a different number of energy stores.

Advantageous embodiments of the invention are defined in the dependent claims.

According to an advantageous embodiment of the invention it is provided that the energy storage devices provided in the at least one energy storage device are of identical design.

A search for the right combination of different strength energy storage devices for the respective requirement is therefore no longer necessary, since the energy storage devices are designed in the same way.

The actuator drive is user-friendly for the operator and / or fitter by filling the at least two receptacles with a type of energy storage device to assemble and / or to adjust.

According to an advantageous embodiment of the invention it is provided that the at least one energy storage device has a base, preferably mounted on a housing about an axis of rotation, and a bearing device spaced therefrom, the energy storage device provided in the at least one energy storage device between the base and the Storage device are clamped.

As a result, a secure positioning of the at least one energy storage device in the at least one energy storage device is particularly promoted, with no separate holding devices being necessary in a space between the storage device and the base.

According to a preferred embodiment of the invention it is provided that an empty space is arranged on those receptacles of the at least one energy storage device on which no energy storage device is arranged.

This enables a lighter actuator arm drive. In addition, the at least one energy store can be conveniently removed from an arrangement between the base and the bearing device, for example by pushing out the at least one energy store.

According to an advantageous embodiment of the invention it is provided that the energy storage devices provided in the at least one energy storage device can be removed and / or supplied to the at least one energy storage device individually, i.e. independently of adjacent energy storage devices.

[0023] As a result, variable loading of the at least one energy storage device is particularly favored, since energy storage devices can be removed and / or inserted independently of energy storage devices already located in the energy storage device. In addition, it is easier to equip the actuator drive with energy storage devices in the position of use on the furniture.

An advantageous variant consists in that the at least one energy store is designed in the form of a helical spring.

The technical effect of a helical spring is that the energy accumulators take up little space in the actuating arm drive and also ensure a high damping effect and particularly favorable force transmission with a long service life.

It has proven advantageous that the at least two receptacles are designed in the same way.

This enables the user of the actuating arm drive to arrange the at least one energy storage device in any receptacle of the at least two receptacles, thus saving time in filling the at least two receptacles.

The at least two receptacles can easily be filled by the user and / or fitter with the same type of energy storage mechanism with the number of energy storage mechanisms required by the requirements.

The identically designed recordings offer a user-friendly and flexible handling of the actuating arm drive itself and / or during assembly and / or when converting the actuating arm drive.

According to an advantageous embodiment of the invention it is provided that the at least two receptacles are arranged essentially in parallel.

This enables a favored energy storage load and / or transmission of the forces acting during the actuation of the actuator drive in a defined direction.

It has been found to be advantageous that the actuating arm drive comprises a housing, preferably wherein at least one, particularly preferably actuatable from an end face of the housing of the actuating arm drive, adjusting device is provided for setting a spring preload of the at least one energy storage device.

This makes it possible for the magnitude of the force to be applied to the actuating arm to be adjustable in addition to the force which the at least one force storage device produces via the force storage device.

If the storage device is arranged essentially parallel to the end face, a particularly favorable force transmission takes place via the energy storage device located in the energy storage device to the actuating arm.

It has proven to be advantageous that the transmission mechanism comprises an actuating part which is coupled in movement to the actuating arm, in particular in the form of a lever mechanism.

By means of an actuating part, which can represent the transmission mechanism, a force transmission from the at least one energy storage device to the actuating arm is particularly promoted. By using a lever mechanism, lever arms of the lever mechanism can cause a force-saving movement of the actuating arm.

It has been found to be favorable that at least one power transmission lever for power transmission of the actuating part is arranged on the actuating part and the bearing device.

By means of at least one force transmission lever, the force accumulators of the at least one force storage device can transmit the forces particularly favorably to the actuating part and subsequently to the actuating arm.

It is particularly preferably provided that at least one damping device for

Damping of the actuating part and / or the actuating arm is arranged on the housing and / or on the actuating part.

The at least one damping device enables a homogeneous movement of the actuating arm, with jerky movements of the actuating part - which can in particular reduce the service life of the actuating arm drive - are prevented.

According to an advantageous embodiment of the invention it is provided that the control part is designed as a 7-swivel mechanism, and / or is rotatably connected to the housing via at least one axis fixed to the housing, wherein the control part comprises at least one knee, preferably wherein the at least one knee joint can be actuated continuously and / or with an essentially continuous expenditure of force.

This makes it possible to ensure a gentle, controlled and continuous transmission of forces in spite of limited space resources.

[0043] In general, however, the actuating part can also act via more or fewer swivel joints.

[0044] Changing torques are particularly favorably absorbed by an increased number of knees.

It has been found to be favorable that at least one fastening device, which can be actuated preferably from one end face of the housing of the actuating arm drive, is provided for fastening the housing of the actuating arm drive in a recess of the furniture body.

This makes it possible for the actuator drive to be firmly anchored in the furniture and for the actuator drive to be fastened in side walls of the furniture body in a space-saving manner.

It is particularly preferred that in the set with at least two actuating arm drives the at least two energy stores are designed as helical springs of the same type.

However, it can generally also be a different type of springs of the same type.

In the prior art, an energy storage device is used during assembly, which must already be adapted to the circumstances. The solution here offers more flexibility with at least two receptacles and at least one, particularly preferably similar and / or identical, energy storage device, since the energy storage device can be equipped with the necessary tensile or compressive force purely via the amount of similar and / or identical energy storage devices used.

This is particularly user-friendly because the user and / or fitter only has to take the correct number of similar and / or identical energy storage devices, for example from a box, when handling the actuator drive.

This also offers a particularly high degree of flexibility in the use of the actuating arm drive, since one and the same actuating arm drive can be used, for example, with moveable furniture parts of different weights, due to a changed number of energy stores in the existing receptacles.

Apart from the equipping of the energy storage device by an individual number of energy storage devices, the same actuator arm drive can be used for different furniture and different movable furniture parts and also ensures a possible adaptation of the application of force by changing the number of energy storage devices, whereby the movable furniture part with more or less effort is required to move.

A type and a material-specific nature of the at least one energy store such as the number of springs and / or the extensibility and the dimensioning of the at least one energy store are generally arbitrary; however, these are particularly preferably adapted to the properties of the furniture part to be moved, such as weight and / or expansion.

If more energy stores are required, there is no need to dismantle the energy stores already located in the at least two receptacles. If there are too many energy stores in the at least two receptacles, the excess number of energy stores can be removed until the desired force compensation is guaranteed by the remaining energy stores.

In a preferred embodiment it is provided that the housing comprises at least one viewing window, it is preferably provided that at least one film is arranged over the at least one viewing window.

This makes it possible for the user and / or fitter of the actuating arm drive to be able to recognize the number of existing energy stores. This is also possible with an at least partially transparent film arranged over the viewing window, the film reducing contamination of the energy storage device.

The type, shape and position of the at least one viewing window is arbitrary per se. It is preferred that the at least one viewing window is arranged at least partially above the at least one energy storage device.

It is particularly preferred that the at least one energy store is freely accessible through the at least one viewing window from at least one side. This reduces the lateral extent of the actuator drive, since the at least one energy storage device can protrude with a diameter into the at least one viewing window and is not limited by a material of the housing.

Furthermore, it is particularly preferred that the at least one viewing window is covered by a cover made of plastic, glass or a film in order to protect the construction from dirt and / or chips from a side wall and / or the operator and / or fitter from injuries . However, technical implementation without a cover is also possible according to the invention.

The viewing window can comprise round, angular and / or any desired geometries.

According to an advantageous embodiment of the invention it is provided that the furniture body comprises at least one side wall, wherein at least one recess is arranged in the at least one side wall and the first actuator arm drive part is arranged at least partially, preferably completely, in the at least one recess, preferably wherein the at least one recess and / or the first actuating arm drive part is essentially cuboid and the first actuating arm drive part is covered on at least four, preferably on five, sides by a material of the at least one side wall.

This enables a particularly space-saving method of installation and, in addition, an aesthetically pleasing construction and / or an aesthetically pleasing piece of furniture is provided by at least some areas of the actuating arm drive being covered by the at least one side wall.

Fig. 1 shows an actuating arm drive 1 for moving a movable furniture part 2, comprising an actuating arm 4 for moving the movable furniture part 2, an energy storage device 5 for applying force to the actuating arm 4 and a transmission mechanism 6 for transmitting a force from the energy storage device 5 to the Control arm 4.

The actuating arm drive 1 is mounted on the inside on a side wall of a piece of furniture 13 by means of fastening elements, the actuating arm drive 1 being visible through a schematically illustrated opening point.

The energy storage device 5 has six receptacles 9 for energy storage 10. The number of receptacles 9 is generally arbitrary. Particularly preferred, however, is a number of receptacles 9 which ensure both convenience in filling the receptacles 9 with energy storage 10 and the technical benefit of a compact construction of the actuator drive 1.

Two energy stores 10 are arranged in the six receptacles 9 and four receptacles 9 are not equipped with any energy storage mechanism 10. The energy storage devices 10 are designed in a similar and identical manner. The number of energy stores 10 actually present in the receptacles 9 depends on the dimensions of the receptacles 9, the nature of the energy stores 10 (material, strength, etc.) and the properties of the furniture part 2 to be moved.

The shape of the receptacles 9 is arbitrary per se. Particularly preferred, however, are receptacles 9 which are suitable for helical springs 11 and / or ensure the transmission of both tensile and compressive forces between the energy stores 10 and the actuating arm 4.

The two energy accumulators 10 are designed in the form of two helical springs 11.

The movable furniture part 2 of the furniture 13 is arranged with an actuating arm drive 1 for moving the movable furniture part 2.

2 shows the actuator drive 1 without a movable furniture part 2 and furniture 13. The number of fastening elements for the assembly is generally arbitrary.

Four energy accumulators 10 designed in the same way are arranged in the six receptacles 9. The exemplary embodiment shown of the actuating arm drive 1 differs from the exemplary embodiment of the actuating arm drive 1 shown in FIG. 1 only in the number of energy accumulators 10 which are arranged in the receptacles 9.

The six receptacles 9 are designed in the same way and are arranged parallel to one another.

A housing 25 covers the transmission mechanism 6. The housing 25 has a recess, whereby the receptacles 9 and the energy storage mechanism 10 are visible. The shape of the recess is generally arbitrary.

In one embodiment, the housing 25 can also be designed without the recess for aesthetic reasons. A film 29 which covers the at least one viewing window 16 is not shown for reasons of clarity.

The arrangement of the energy storage mechanism 10 in the receptacles 9 is selected to be symmetrical. The

The position of the receptacles 9 filled with the energy storage mechanism 10 can also be selected asymmetrically.

The arrangement and number of energy storage mechanisms 10 can be visually detected via a viewing window 16. The viewing window 16 is arranged essentially above the receptacles 9.

3a shows the actuating arm drive 1 without a front part of the housing 25, whereby the transmission mechanism 6 can be seen. The actuating arm 4 is coupled in terms of movement to the actuating part 7 as a transmission mechanism 6. The control part 7 is designed in the form of a lever mechanism 8.

The lever mechanism 8 has five elbows 12, the five elbows 12 being infinitely variable and actuatable with an essentially continuous expenditure of force. The number of knees 12 is generally arbitrary.

On an end face 26 of the housing 25, an adjusting device 24 for adjusting a force which acts on the adjusting part 7, which is designed in the form of a 7-pivot joint mechanism, can be actuated. A point of application of a 7-pivot kinematics or some other control part 7 on the energy storage device 5 is variably adjustable by the setting device 24, whereby the application of force to the actuating arm 4, in particular in the position of use of the actuating arm drive 1, can be adjusted by a changed acting lever arm. This is indicated by a double arrow in the illustration.

The energy storage device 5 has a base 32 mounted on the housing 25 about an axis of rotation 31 and a bearing device 30 spaced therefrom. The energy storage devices 10 provided in the energy storage device 5 are clamped between the base 32 and the bearing device 30.

The bearing device 30 is arranged essentially parallel to the end face 26. The receptacles 9 are designed as part of the storage device 30.

The control part 7 is rotatably connected to the housing 25 via two axles 27 fixed to the housing. A power transmission lever 14 is arranged for power transmission of the actuating part 7 on the actuating part 7 and the bearing device 30.

The levers of the actuating part 7 and the force transmission lever 14 are designed in two parts, connected via lever axles and connected to the housing 25 via the lever axles.

The actuating part 7 defines the movement of the actuating arm 4, the force transmission lever 14 transmitting the force from the energy storage devices 10 to the actuating part 7.

The embodiment has six energy accumulators 10 in the form of similar and identically designed coil springs 11 which are arranged in the six existing receptacles 9.

3b shows an actuator drive 1 according to the embodiment shown in FIG. 1, the embodiment shown only differing in the missing front part of the housing 25 and in that the actuator drive 1 is not mounted on any furniture part 13 and no movable furniture part 2 is.

An empty space 33 is arranged on those receptacles 9 of the energy storage device 5 on which no energy storage device 10 is arranged. Since the empty space 33 is present, there is no separate spring guide for the energy storage device 10, which is not necessary, in particular due to the structural design of the energy storage device 5.

The energy storage device 10 provided in the energy storage device 5 can be removed from and supplied to the energy storage device 5 individually, that is to say independently of adjacent energy storage devices 10. Since the energy storage devices 10 can be fed individually to the energy storage device 5 of the actuating arm drive 1, the energy storage devices 10 do not have to be removed from or supplied to the energy storage device 5 together, for example, in one package.

In addition to the receptacles 9 of the storage device 30 and possibly receptacles of the ba-

Sis 32 no additional connecting elements are necessary for the arrangement of the energy storage device 10 in the energy storage device. The energy accumulators 10 are arranged on the base via receptacles in the base 32.

The adjusting device 24 can be seen by means of which the magnitude of the force with which the actuating arm 1 can be acted upon can be adjusted.

Furthermore, as in the case shown, a damping device 17 can be provided for damping the movement of the actuating arm 4, in particular for damping the movement of the actuating arm 4 into a closed position and / or into an open end position.

The damping device 17 for damping the actuating part 7 and the actuating arm 4 is arranged on the housing 25 and on the actuating part 7.

Fig. 4 shows an actuator drive 1 according to the embodiment shown in Fig. 2, wherein the front part of the housing 25 is dismantled. The actuating part 7 in the form of a lever mechanism 8 is thus recognizable as a transmission mechanism 6.

The five elbows 12 are arranged between the energy storage device 5 and the actuating arm 4 and can generally be partially, largely or entirely covered by the housing 25.

From an end face 26 of the housing 25 of the actuating arm drive 1, a fastening device 28 for fastening the housing 25 of the actuating arm drive 1 in a recess 23 of the furniture body 18 can be actuated, which cutting elements for fixing the first actuating arm drive part 20 in the recess 23 of the side wall 22 of the Furniture body 18 includes.

The actuating arm drive 1 is shown together with several energy stores 10, which are present in a box 15. Four energy stores 10 are already arranged in the actuator drive 1 and if the actuator drive 1 has to transmit less or more forces, the energy stores 10 can be placed back in the box 15 or removed from the box 15 for reception.

The user and / or fitter does not have to have the appropriate energy storage device 10, but can adjust the total for the energy storage device 10 required forces via a space-saving energy storage device 5 through the ideal number of energy storage devices 10 from the box 15.

Fig. 5a shows a piece of furniture 13 with a furniture body 18, a relative to the furniture body 18 movably mounted movable furniture part 2 and two actuating arm drives 1 for the movable mounting of the movable furniture part 2 relative to the furniture body 18. In the illustration, an actuator 1 is through the movable furniture part 2 in the form of a furniture flap 19 covered.

The movable furniture part 2 can, as in the case shown, be a furniture flap 19 movable about a horizontal axis. The movable furniture part 2 can comprise a frame with a glass insert.

The two actuating arm drives 1 are fastened in two recesses 23.

The actuating arm 4 is mounted about an axis of rotation 3. A rotation about the axis of rotation 3 is initiated by the movable furniture part 2 and follows a defined coupled movement of the movable furniture part 2 and the actuating part 7.

Fig. 5b shows a partially exploded view of four components of the furniture 13. In this and the embodiments described above, the fastening elements include both cutting elements in the form of cutting teeth and pressing elements in the form of substantially parallel to the wall of the recess 6 alignable contact surfaces.

The actuating arm drive 1 comprises a first actuating arm drive part 20 and a second actuating arm drive part 21, the first actuating arm drive part 20 being inserted into a side wall 22 and the second actuating arm drive part 21 being arranged on the movable furniture part 2.
