Definitions
- the present invention relates to an actuator for driving a movably mounted furniture part of a piece of furniture with the features of the preamble of claim 1 and a piece of furniture with at least one such actuator.
- actuators for driving movably mounted furniture parts of a piece of furniture with energy accumulators the springs or spring assemblies of which have guide devices to avoid buckling movements of the springs when the energy accumulator is compressed, are known.
- guide devices arranged in the interior of the spring in the form of rods arranged, for example, in an interior formed by the spring are known. Since the distance between the base parts, between which the spring is arranged, is limited in a fully compressed position of the energy storage device - and thus the possible stroke of such an energy storage device - is limited by such internal rods serving to guide the spring, such a guide cannot be over the extend the entire length of the spring to be supported. For this reason, such energy accumulators usually and necessarily have additional external guide devices in the form of, for example, cup-shaped or pot-shaped spring bearings, which enclose the spring on the outside over a large area.
- a disadvantage of actuators known from the prior art with energy stores as described above is the inadequate support of the spring by the guide device arranged in the interior of the spring. This can result in buckling of the spring and inadequate guidance of the energy storage device when it is compressed, for example. Such inadequate guidance can also have a negative effect on the spring characteristic and the efficiency of the energy store.
- energy accumulators of actuators known from the prior art have additional structural measures on, which lead to increased labor and material input as well as to an increased space requirement of such an energy storage device (and thus of the actuator).
- Such inadequate guidance of the spring of an energy store can also lead to undesirable noise development when the actuator is actuated, since a buckling spring can drag along an internal or external guide.
- the object of the present invention is therefore to provide an actuator that is improved over the prior art and a piece of furniture with at least one such actuator.
- the set object is achieved by an actuator with the features of claim 1 and a piece of furniture with at least one such actuator.
- Advantageous embodiments of the invention are defined in the dependent claims.
- the guide device is designed in such a way that it supports the at least one spring against buckling of the spring over the entire length of the spring and in every position of the spring which results from a relative movement of the at least two base parts to one another, in each Compression position of the energy storage device, with which a position of the spring is connected in each case, a secure guidance of the spring can be guaranteed even with great pretension and great spring hardness.
- the guide device supports the spring during compression in such a way that the spring is essentially only deformed along the longitudinal axis of the spring and the spring moves radially or laterally to the direction of movement of the relative movement of the at least two base parts be prevented.
- Such a guide can have a positive effect on the spring characteristic of the spring and these run particularly linear, for example.
- the efficiency of the spring or the energy store can also be optimized, since an essentially straight relative movement of the at least two base parts can be converted into an essentially straight compression or expansion movement of the spring. In this way, a compact and efficient energy store can be provided.
- Such a guide device can also contribute to reducing disruptive noises when the actuator is actuated, since it is often possible to avoid sudden buckling of the spring (s).
- the length of the guide device can be adapted to the length of the at least one spring. This makes it easy to achieve that the spring is supported against buckling over its entire length in every position, but the possible change in length of the spring - and thus the possible stroke of the energy storage device - is not restricted by the guide device.
- the guide device can be guided at least partially through one of the base parts during the relative movement of the at least two base parts.
- This allows the spring to be supported over its entire length in any position of the spring and in any position of the two base parts with respect to one another.
- This also allows the length of the guide device to be easily adapted to the length of the spring.
- it is thereby possible to achieve guidance of the relative movement of the two base parts with respect to one another and thus, for example, with a suitable design of the guide device, enable linear guidance of the relative movement of the base parts.
- the actuator has a housing and the guide device can be guided through one of the base parts in a direction facing an interior of the housing. This enables a particularly compact design of the energy store and thus of the actuator can be achieved because when the actuator is actuated, no parts of the guide device or the energy store protrude from the actuator housing.
- a base part of the energy store can be mounted on the housing in a fixed or pivotable manner.
- the actuating drive has a transmission mechanism for applying force to the at least one actuating arm through the energy store and the transmission mechanism - preferably directly - interacts with the base part through which the guide device can at least partially be guided.
- the transmission mechanism can be used to set the transmission ratio of the force transmitted from the energy store to the actuating arm.
- the guide device consists of a first material - preferably a plastic - at least in the areas facing the spring, which differs from a second material from which the spring is formed.
- friction values between the guide device and the spring, especially the inner area of the spring can be optimized and the generation of noise when the spring and the guide device come into contact can thus also be reduced.
- the guide device can for example be made of a plastic such as polyoxymethylene (POM). It is also possible that the guide device is made of a metal material and has a corresponding coating in the areas facing the spring.
- the guide device has sleeve parts that correspond to one another, the sleeve parts being arranged on the base parts and projecting from them and an at least partial overlap in the circumferential direction and / or in the radial direction in each position of the at least two base parts that can be moved relative to one another exhibit.
- the sleeve parts that correspond to one another can basically be formed by two axially displaceable parts, which can be at least partially nested in one another or arranged in an engaging manner. By arranging the sleeve parts on the base parts, it can be ensured that the sleeve parts follow the movements of the base parts.
- the sleeve parts can also each be designed in one piece with a base assigned to the guide device. Such a base can also serve to support (abutment) the springs. A play of about 0.1 millimeter can be provided in the radial direction between the sleeve parts.
- the sleeve parts have a longitudinal guide in the form of at least one groove formed on one sleeve part and a profile web corresponding to this and formed on the other sleeve part.
- the support of the spring provided by the guide device can be increased and the space required by the guide device inside the spring can also be minimized.
- the guide device has at least one - preferably bolt-shaped - guide element and at least one guide opening for the guide element, the at least one guide element being arranged on one of the base parts and the at least one guide opening corresponding to the guide element being formed in the other base part.
- the guide element can extend through a guide opening in any relative position of the base parts of an energy storage mechanism in the assembled position, that is to say with an energy storage mechanism installed in the actuator.
- a guide device designed in this way can also guide the relative movement of the base parts with respect to one another.
- the guide element can be arranged at least partially in one of the sleeve parts or is formed by one of the sleeve parts.
- Such a guide element can Reinforcement of corresponding sleeve parts are used.
- a guide element which corresponds to a guide opening in the other base part and can be passed through it can also be formed by one of the sleeve parts.
- a sleeve part formed around the area of a guide opening can also serve to guide a guide element.
- At least one sleeve part of the guide device and / or at least one guide element of the guide device can be guided at least partially through at least one guide opening formed in the other base part in at least one position of the at least two base parts that can be moved relative to one another.
- a particularly stable guide device which supports the spring over the entire length of the spring in every position of the spring and in every relative position of the two base parts to one another against buckling of the spring, while simultaneously guiding the base parts to one another, can be achieved.
- a further spring can be arranged coaxially in the interior of the at least one spring.
- the bandwidth and size of the force that can be provided by the energy store can be increased and the actuator can also be better adapted to a furniture part to be driven.
- the dimensions of the energy store and thus of the actuator can also advantageously be reduced as a result.
- the further, coaxially arranged spring can have a direction of winding opposite to that of the external spring.
- the shape of the guide device essentially corresponds to the inner contour of the at least one spring.
- the inner contour of the spring can essentially correspond to a cylinder jacket and the guide device can thus essentially have a cylindrical cross section. In this way it can be achieved, for example, that the spring is supported against buckling radially in all directions and over the entire length of the spring.
- a play of 0.1 to 1 millimeter, preferably about 0.3 mm, can be provided between the guide device and the inner contour of the springs.
- Protection is also desired for a piece of furniture with at least one actuator as described above and a furniture part movably mounted on it.

- the first sleeve parts 12 are arranged on the first base part 7 and the second sleeve parts 13 are arranged on the second base part 8.
- the guide elements 17 in the form of the bolt elements 22 are arranged on the first base part 7 and pass through guide openings 18 formed in the second base part 8, the sleeve parts 13 also serving to guide the guide elements 17 (see on FIG Figure 3b ).
- the actuator 1 is shown in a second pivot position, which corresponds to a closed position of a furniture part 2 of a piece of furniture 3 driven by the actuator 1.
- the energy store 5 is in a second compression position, which is characterized in that the length L1 of the springs 6 and the length L2 of the guide device 9 essentially has a minimum value.
- the two base parts 7, 8 are therefore essentially at a minimal distance from one another.
- the length L2 of the guide device 9 arranged in the interior of the springs 6 can be adapted to the length L1 of the springs 6, the springs 6 can also be supported against buckling over their entire length L1 in this second compression position of the energy accumulator 5
- the stroke of the energy store 5 - or the minimum possible distance between the two base parts 7, 8 - is not limited by the guide device 9.
- part of the guide device 9 can be guided through the second base part 8 in a direction facing the interior of the housing 10, with the guide element 17 configured as a bolt element 22 specifically passing through the guide openings 18 configured in the second base part 8.

- the sleeve parts 12 have radially protruding profile webs 16 which correspond to grooves 15 in the sleeve parts 13.
- the sleeve parts 12 also have extensions running in the longitudinal direction for the formation of guide elements 17, which in the assembled state of the energy store 5 (see for example FIG Figures 8a-8c and Figures 9a-9c ) engage in the sleeve parts 13 arranged on the other base part 8.
- guide elements 17 which in the assembled state of the energy store 5 (see for example FIG Figures 8a-8c and Figures 9a-9c ) engage in the sleeve parts 13 arranged on the other base part 8.
- the guide device 9 - as mentioned - has guide elements 17, which extend in the longitudinal direction of the springs 6, 19 when the energy store 5 is installed and which can be passed through guide openings 18 formed in the second base part 8 (in this embodiment) .

- the springs 6, 19 of the energy accumulator 5 shown here are designed in the form of spiral springs, which can be arranged coaxially (that is, nested) with respect to one another, and are shown compressed for reasons of illustration.
- Figures 5a and 5b each show an embodiment of a guide device 9 with different lengths L2 of the guide device 9.
- the guide device 9 has sleeve parts 12, 13 which correspond to one another and which are each formed in one piece with a base 20 or a further base 21.
- the sleeve parts 12 of the base 20 have recesses in the form of the grooves 15, into which the radially protruding profile webs 16 of the sleeve parts 13 of the further base 21 can engage.

Description
Die vorliegende Erfindung betrifft einen Stellantrieb zum Antrieb eines bewegbar gelagerten Möbelteils eines Möbels mit den Merkmalen des Oberbegriffs des Anspruchs 1 und ein Möbel mit zumindest einem solchen Stellantrieb.The present invention relates to an actuator for driving a movably mounted furniture part of a piece of furniture with the features of the preamble of
Aus dem Stand der Technik sind Stellantriebe zum Antrieb bewegbar gelagerter Möbelteile eines Möbels mit Kraftspeichern, deren Federn bzw. Federpakete Führungsvorrichtungen zur Vermeidung von Knickbewegungen der Federn bei einer Kompression des Kraftspeichers aufweisen, bekannt. Dabei sind auch im Inneren der Feder angeordnete Führungsvorrichtungen in Form von beispielsweise in einem von der Feder ausgebildeten Innenraum angeordneten Stäben bekannt. Da durch solche der Führung der Feder dienenden innenliegenden Stäbe der Abstand der Basisteile, zwischen welchen die Feder angeordnet ist, in einer vollständig komprimierten Stellung des Kraftspeichers - und somit der mögliche Hub eines solchen Kraftspeichers - limitiert ist, kann sich eine solche Führung nicht über die gesamte Länge der zu stützenden Feder erstrecken. Aus diesem Grund weisen solche Kraftspeicher üblicher- und notwendigerweise zusätzliche außenliegende Führungsvorrichtungen in Form von beispielsweise Becher- bzw. Topf-förmigen Federlagern, welche die Feder außen großräumig umschließen, auf.From the prior art, actuators for driving movably mounted furniture parts of a piece of furniture with energy accumulators, the springs or spring assemblies of which have guide devices to avoid buckling movements of the springs when the energy accumulator is compressed, are known. In this case, guide devices arranged in the interior of the spring in the form of rods arranged, for example, in an interior formed by the spring, are known. Since the distance between the base parts, between which the spring is arranged, is limited in a fully compressed position of the energy storage device - and thus the possible stroke of such an energy storage device - is limited by such internal rods serving to guide the spring, such a guide cannot be over the extend the entire length of the spring to be supported. For this reason, such energy accumulators usually and necessarily have additional external guide devices in the form of, for example, cup-shaped or pot-shaped spring bearings, which enclose the spring on the outside over a large area.
Nachteilig an aus dem Stand der Technik bekannten Stellantrieben mit wie zuvor beschriebenen Kraftspeichern ist dabei die unzureichende Abstützung der Feder durch die im Inneren der Feder angeordnete Führungsvorrichtung. Dadurch kann es zu einem Ausknicken der Feder und einer unzureichenden Führung des Kraftspeichers bei beispielsweise einer Kompression desselben kommen. Eine solche mangelhafte Führung kann sich auch negativ auf die Federkennlinie und die Effizienz des Kraftspeichers auswirken. Um eine hinreichende Führung zu gewährleisten, weisen Kraftspeicher von aus dem Stand der Technik bekannten Stellantrieben zusätzliche bauliche Maßnahmen auf, welche zu erhöhtem Arbeits- und Materialeinsatz sowie zu einem erhöhten Raumbedarf eines solchen Kraftspeichers (und somit des Stellantriebs) führen. Eine solche unzureichende Führung der Feder eines Kraftspeichers kann auch zu unerwünschter Geräuschentwicklung bei Betätigung des Stellantriebs führen, da eine ausknickende Feder an einer innen- bzw. auch außenliegenden Führung entlangschleifen kann.A disadvantage of actuators known from the prior art with energy stores as described above is the inadequate support of the spring by the guide device arranged in the interior of the spring. This can result in buckling of the spring and inadequate guidance of the energy storage device when it is compressed, for example. Such inadequate guidance can also have a negative effect on the spring characteristic and the efficiency of the energy store. In order to ensure adequate guidance, energy accumulators of actuators known from the prior art have additional structural measures on, which lead to increased labor and material input as well as to an increased space requirement of such an energy storage device (and thus of the actuator). Such inadequate guidance of the spring of an energy store can also lead to undesirable noise development when the actuator is actuated, since a buckling spring can drag along an internal or external guide.
Aufgabe der vorliegenden Erfindung ist es daher, einen gegenüber dem Stand der Technik verbesserten Stellantrieb und ein Möbel mit zumindest einem solchen Stellantrieb anzugeben.The object of the present invention is therefore to provide an actuator that is improved over the prior art and a piece of furniture with at least one such actuator.
Insbesondere sollen die oben genannten Nachteile hinsichtlich der Geräuschentwicklung, des Raumbedarfs und der Effizienz behoben werden.In particular, the above-mentioned disadvantages with regard to noise development, space requirements and efficiency are to be eliminated.
Die gestellte Aufgabe wird durch einen Stellantrieb mit den Merkmalen des Anspruchs 1 und ein Möbel mit zumindest einem solchen Stellantrieb gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.The set object is achieved by an actuator with the features of
Dadurch, dass die Führungsvorrichtung derart ausgebildet ist, dass sie die zumindest eine Feder über die gesamte Länge der Feder und in jeder Stellung der Feder, welche sich durch eine Relativbewegung der zumindest zwei Basisteile zueinander ergibt, gegen ein Ausknicken der Feder abstützt, kann in jeder Kompressionsstellung des Kraftspeichers, mit welcher jeweils eine Stellung der Feder verbunden ist, eine sichere Führung der Feder selbst bei großen Vorspannungen und großen Federhärten gewährleistet werden. Sind die Federn als Spiralfedern ausgebildet, so wird durch die Führungsvorrichtung die Feder bei einer Kompression derart abgestützt, dass sich die Feder im Wesentlichen nur entlang der Längsachse der Feder verformt und radiale bzw. seitlich zur Bewegungsrichtung der Relativbewegung der zumindest zwei Basisteile gerichtete Bewegungen der Feder verhindert werden. Eine solche Führung kann sich positiv auf die Federkennlinie der Feder auswirken und diese beispielsweise besonders linear verlaufen. Auch kann dadurch die Effizienz der Feder bzw. des Kraftspeichers optimiert werden, da eine im Wesentlichen geradlinig verlaufende Relativbewegung der zumindest zwei Basisteile in eine im Wesentlichen geradlinig, also frei von Ausknickungen verlaufende Kompressions- oder Expansionsbewegung der Feder umgesetzt werden kann. So kann ein kompakter und effizienter Kraftspeicher bereitgestellt werden. Auch kann eine solche Führungsvorrichtung zur Verminderung von störenden Geräuschen bei Betätigung des Stellantriebs beitragen, da sich oft schlagartig auftretenden Ausknickungen der Feder(n) vermeiden lassen.Because the guide device is designed in such a way that it supports the at least one spring against buckling of the spring over the entire length of the spring and in every position of the spring which results from a relative movement of the at least two base parts to one another, in each Compression position of the energy storage device, with which a position of the spring is connected in each case, a secure guidance of the spring can be guaranteed even with great pretension and great spring hardness. If the springs are designed as spiral springs, the guide device supports the spring during compression in such a way that the spring is essentially only deformed along the longitudinal axis of the spring and the spring moves radially or laterally to the direction of movement of the relative movement of the at least two base parts be prevented. Such a guide can have a positive effect on the spring characteristic of the spring and these run particularly linear, for example. The efficiency of the spring or the energy store can also be optimized, since an essentially straight relative movement of the at least two base parts can be converted into an essentially straight compression or expansion movement of the spring. In this way, a compact and efficient energy store can be provided. Such a guide device can also contribute to reducing disruptive noises when the actuator is actuated, since it is often possible to avoid sudden buckling of the spring (s).
Dabei kann vorteilhaft sein, dass Länge der Führungsvorrichtung an die Länge der zumindest einen Feder anpassbar ist. Dadurch kann einfach erreicht werden, dass die Feder in jeder Stellung über ihre gesamte Länge gegen ein Ausknicken abgestützt wird, die mögliche Längenänderung der Feder - und somit der mögliche Hub des Kraftspeichers - jedoch nicht durch die Führungsvorrichtung beschränkt wird.It can be advantageous that the length of the guide device can be adapted to the length of the at least one spring. This makes it easy to achieve that the spring is supported against buckling over its entire length in every position, but the possible change in length of the spring - and thus the possible stroke of the energy storage device - is not restricted by the guide device.
Weiter kann dabei vorteilhaft sein, dass die Führungsvorrichtung bei der Relativbewegung der zumindest zwei Basisteile zumindest teilweise durch eines der Basisteile hindurchführbar ist. Dadurch lässt sich ein Abstützen der Feder über ihre gesamte Länge in jeder Stellung der Feder und in jeder Stellung der zwei Basisteile zueinander einfach ermöglichen. Auch kann sich dadurch die Länge der Führungsvorrichtung einfach an die Länge der Feder anpassen. Zudem kann sich dadurch eine Führung der Relativbewegung der zwei Basisteile zueinander erreichen lassen und so beispielsweise bei geeigneter Ausbildung der Führungsvorrichtung eine Linearführung der Relativbewegung der Basisteile ermöglicht werden.It can furthermore be advantageous that the guide device can be guided at least partially through one of the base parts during the relative movement of the at least two base parts. This allows the spring to be supported over its entire length in any position of the spring and in any position of the two base parts with respect to one another. This also allows the length of the guide device to be easily adapted to the length of the spring. In addition, it is thereby possible to achieve guidance of the relative movement of the two base parts with respect to one another and thus, for example, with a suitable design of the guide device, enable linear guidance of the relative movement of the base parts.
Dabei kann auch vorteilhaft sein, dass der Stellantrieb ein Gehäuse aufweist und die Führungsvorrichtung aus einem der Basisteile in eine einem Innenraum des Gehäuses zugewandte Richtung hindurchführbar ist. Dadurch kann eine besonders kompakte Bauform des Kraftspeichers und somit des Stellantriebs erreicht werden, da bei einer Betätigung des Stellantriebs keine Teile der Führungsvorrichtung bzw. des Kraftspeichers aus dem Gehäuse des Stellantriebs hervortreten. Dabei kann ein Basisteil des Kraftspeichers zum Gehäuse feststehend bzw. schwenkbar an diesem gelagert sein.It can also be advantageous that the actuator has a housing and the guide device can be guided through one of the base parts in a direction facing an interior of the housing. This enables a particularly compact design of the energy store and thus of the actuator can be achieved because when the actuator is actuated, no parts of the guide device or the energy store protrude from the actuator housing. A base part of the energy store can be mounted on the housing in a fixed or pivotable manner.
Dabei kann auch vorteilhaft sein, dass der Stellantrieb einen Übertragungsmechanismus zur Kraftbeaufschlagung des wenigstens einen Stellarms durch den Kraftspeicher aufweist und der Übertragungsmechanismus - vorzugsweise direkt - mit dem Basisteil, durch welchen die Führungsvorrichtung zumindest teilweise hindurchführbar ist, zusammenwirkt. Der Übertragungsmechanismus kann dabei der Einstellung des Übersetzungsverhältnis der vom Kraftspeicher auf den Stellarm übertragenen Kraft dienen.It can also be advantageous that the actuating drive has a transmission mechanism for applying force to the at least one actuating arm through the energy store and the transmission mechanism - preferably directly - interacts with the base part through which the guide device can at least partially be guided. The transmission mechanism can be used to set the transmission ratio of the force transmitted from the energy store to the actuating arm.
Es kann von Vorteil sein, dass die Führungsvorrichtung zumindest in der Feder zugewandten Bereichen aus einem ersten Material - vorzugsweise aus einem Kunststoff - besteht, welches von einem zweiten Material, aus welchem die Feder ausgebildet ist, abweicht. So können sich beispielsweise Reibungswerte zwischen der Führungsvorrichtung und der Feder, speziell dem Innenbereich der Feder, optimieren lassen und so auch eine Geräuschentwicklung bei Kontakt der Feder und der Führungsvorrichtung verringern lassen. Die Führungsvorrichtung kann beispielsweise aus einem Kunststoff, wie etwa Polyoximethylen (POM) ausgebildet sein. Ebenso ist es möglich, dass die Führungsvorrichtung aus einem Metallwerkstoff gefertigt ist und in der Feder zugewandten Bereichen eine entsprechende Beschichtung aufweist.It can be advantageous that the guide device consists of a first material - preferably a plastic - at least in the areas facing the spring, which differs from a second material from which the spring is formed. For example, friction values between the guide device and the spring, especially the inner area of the spring, can be optimized and the generation of noise when the spring and the guide device come into contact can thus also be reduced. The guide device can for example be made of a plastic such as polyoxymethylene (POM). It is also possible that the guide device is made of a metal material and has a corresponding coating in the areas facing the spring.
Weiter kann es vorteilhaft sein, dass die Führungsvorrichtung miteinander korrespondierende Hülsenteile aufweist, wobei die Hülsenteile an den Basisteilen angeordnet und von diesen abstehend ausgebildet sind und in jeder Stellung der zumindest zwei relativ zueinander bewegbaren Basisteile einen zumindest teilweisen Überlapp in Umfangsrichtung und/oder in radialer Richtung aufweisen. Die miteinander korrespondierenden Hülsenteile können dabei grundsätzlich von zwei axial zueinander verschiebbaren Teilen, welche sich zumindest teilweise ineinander verschachtelt oder eingreifend anordnen lassen, ausgebildet sein. Durch eine Anordnung der Hülsenteile an den Basisteilen kann sichergestellt werden, dass die Hülsenteile den Bewegungen der Basisteile folgen. Die Hülsenteile können auch jeweils einstückig mit einer der Führungsvorrichtung zugeordneten Basis ausgebildet sein. Eine solche Basis kann zudem der Abstützung (Widerlager) der Federn dienen. Zwischen den Hülsenteilen kann dabei in radialer Richtung ein Spiel von etwa 0,1 Millimeter vorgesehen sein.Furthermore, it can be advantageous that the guide device has sleeve parts that correspond to one another, the sleeve parts being arranged on the base parts and projecting from them and an at least partial overlap in the circumferential direction and / or in the radial direction in each position of the at least two base parts that can be moved relative to one another exhibit. The sleeve parts that correspond to one another can basically be formed by two axially displaceable parts, which can be at least partially nested in one another or arranged in an engaging manner. By arranging the sleeve parts on the base parts, it can be ensured that the sleeve parts follow the movements of the base parts. The sleeve parts can also each be designed in one piece with a base assigned to the guide device. Such a base can also serve to support (abutment) the springs. A play of about 0.1 millimeter can be provided in the radial direction between the sleeve parts.
Dabei kann vorteilhaft sein, dass die Hülsenteile eine Längsführung in Form von zumindest einer an einem Hülsenteil ausgebildeten Nut und eines mit dieser korrespondierenden, am anderen Hülsenteil ausgebildeten Profilstegs aufweisen. Dadurch kann sich die von der Führungsvorrichtung bereitgestellte Abstützung der Feder erhöhen lassen und sich auch der von der Führungsvorrichtung im Inneren der Feder benötigte Raumbedarf minimieren lassen.It can be advantageous that the sleeve parts have a longitudinal guide in the form of at least one groove formed on one sleeve part and a profile web corresponding to this and formed on the other sleeve part. As a result, the support of the spring provided by the guide device can be increased and the space required by the guide device inside the spring can also be minimized.
Auch kann vorteilhaft sein, dass die Führungsvorrichtung zumindest ein - vorzugsweise bolzenförmiges - Führungselement und zumindest eine Führungsöffnung für das Führungselement aufweist, wobei das zumindest eine Führungselement an einem der Basisteile angeordnet ist und die mit dem Führungselement korrespondierende zumindest eine Führungsöffnung im anderen Basisteil ausgebildet ist. Das Führungselement kann dabei in jeder Relativstellung der Basisteile eines Kraftspeichers in Montagelage, also bei im Stellantrieb eingebautem Kraftspeicher, durch eine Führungsöffnung hindurchreichen. Auch kann durch eine so ausgebildete Führungsvorrichtung eine Führung der Relativbewegung der Basisteile zueinander erreicht werden.It can also be advantageous that the guide device has at least one - preferably bolt-shaped - guide element and at least one guide opening for the guide element, the at least one guide element being arranged on one of the base parts and the at least one guide opening corresponding to the guide element being formed in the other base part. The guide element can extend through a guide opening in any relative position of the base parts of an energy storage mechanism in the assembled position, that is to say with an energy storage mechanism installed in the actuator. A guide device designed in this way can also guide the relative movement of the base parts with respect to one another.
Grundsätzlich kann dabei vorteilhaft sein, dass das Führungselement zumindest teilweise in einem der Hülsenteile anordenbar ist oder von einem der Hülsenteile ausgebildet ist. So kann ein solches Führungselement der Verstärkung von miteinander korrespondierenden Hülsenteilen dienen. Auch kann ein mit einer Führungsöffnung im anderen Basisteil korrespondierendes und durch diese hindurchführbares Führungselement von einem der Hülsenteile ausgebildet sein. Ein um den Bereich einer Führungsöffnung ausgebildeter Hülsenteil kann auch der Führung eines Führungselements dienen.In principle, it can be advantageous that the guide element can be arranged at least partially in one of the sleeve parts or is formed by one of the sleeve parts. Such a guide element can Reinforcement of corresponding sleeve parts are used. A guide element which corresponds to a guide opening in the other base part and can be passed through it can also be formed by one of the sleeve parts. A sleeve part formed around the area of a guide opening can also serve to guide a guide element.
So kann es auch von Vorteil sein, dass zumindest ein Hülsenteil der Führungsvorrichtung und/oder zumindest ein Führungselement der Führungsvorrichtung in zumindest einer Stellung der zumindest zwei relativ zueinander bewegbaren Basisteile zumindest teilweise durch zumindest eine im anderen Basisteil ausgebildete Führungsöffnung hindurchführbar ist. Dadurch kann eine besonders stabile Führungsvorrichtung, welche die Feder über die gesamte Länge der Feder in jeder Stellung der Feder und in jeder Relativstellung der zwei Basisteile zueinander gegen ein Ausknicken der Feder abstützen, bei gleichzeitig erfolgender Führung der Basisteile zueinander, erreicht werden.It can also be advantageous that at least one sleeve part of the guide device and / or at least one guide element of the guide device can be guided at least partially through at least one guide opening formed in the other base part in at least one position of the at least two base parts that can be moved relative to one another. As a result, a particularly stable guide device, which supports the spring over the entire length of the spring in every position of the spring and in every relative position of the two base parts to one another against buckling of the spring, while simultaneously guiding the base parts to one another, can be achieved.
Grundsätzlich kann es von Vorteil sein, dass zwischen den Basisteilen nur innenliegende Führungsvorrichtungen angeordnet sind. Dadurch lässt sich ein besonders raumsparender Kraftspeicher und somit ein besonders raumsparender Stellantrieb bereitstellen.In principle, it can be advantageous that only internal guide devices are arranged between the base parts. This makes it possible to provide a particularly space-saving energy store and thus a particularly space-saving actuator.
Auch kann von Vorteil sein, dass im Inneren der zumindest einen Feder eine weitere Feder koaxial anordenbar ist. Dadurch kann sich die Bandbreite und Größe der vom Kraftspeicher bereitstellbaren Kraft erhöhen lassen und auch der Stellantrieb auf ein anzutreibendes Möbelteil besser anpassen lassen. Auch können sich dadurch die Abmessungen des Kraftspeichers und somit des Stellantriebs vorteilhaft verkleinern lassen. Die weitere, koaxial angeordnete Feder kann dabei einen der außenliegenden Feder entgegengesetzten Windungssinn aufweisen.It can also be advantageous that a further spring can be arranged coaxially in the interior of the at least one spring. As a result, the bandwidth and size of the force that can be provided by the energy store can be increased and the actuator can also be better adapted to a furniture part to be driven. The dimensions of the energy store and thus of the actuator can also advantageously be reduced as a result. The further, coaxially arranged spring can have a direction of winding opposite to that of the external spring.
Auch kann es von Vorteil sein, dass die Form der Führungsvorrichtung im Wesentlichen der Innenkontur der zumindest einen Feder entspricht. Die Innenkontur der Feder kann dabei im Wesentlichen einem Zylindermantel entsprechen und die Führungsvorrichtung somit im Wesentlichen einen zylindrischen Querschnitt aufweisen. Dadurch kann beispielsweise erreicht werden, dass eine Abstützung der Feder gegen ein Ausknicken radial in alle Richtungen und über die gesamte Länge der Feder erfolgt. Dabei kann zwischen der Führungsvorrichtung und der Innenkontur der Federn ein Spiel von 0,1 bis 1 Millimeter, vorzugsweise etwa 0,3mm, vorgesehen sein.It can also be advantageous that the shape of the guide device essentially corresponds to the inner contour of the at least one spring. The inner contour of the spring can essentially correspond to a cylinder jacket and the guide device can thus essentially have a cylindrical cross section. In this way it can be achieved, for example, that the spring is supported against buckling radially in all directions and over the entire length of the spring. A play of 0.1 to 1 millimeter, preferably about 0.3 mm, can be provided between the guide device and the inner contour of the springs.
Schutz wird auch begehrt für ein Möbel mit zumindest einem wie zuvor beschriebenen Stellantrieb und einem bewegbar an diesem gelagerten Möbelteil.Protection is also desired for a piece of furniture with at least one actuator as described above and a furniture part movably mounted on it.
