Definitions
- the invention relates to a damping unit for a sliding element, in particular a movable furniture part, a movable element of a household appliance or a sliding or folding door.
- the damping unit has a linearly guided driver which interacts with an activator connected directly or indirectly to the sliding element and which is coupled to a linear damper, the linear damper having a damping path that is longer than a displacement path of the driver.
- Such sliding elements are, for example, movable furniture parts or movable elements of a household appliance, such as. B. a drawer, also referred to as a drawer, an equipment rack or the like, which are usually mounted on a guide device so that they can be pulled out of a furniture body or household appliance.
- a guide device is also referred to as a pull-out device.
- Movable sliding doors, furniture doors as well as living room doors, which are mounted on a guide rail via guide elements are also to be regarded as sliding elements.
- Folding doors, in which at least a part of the door is movably guided also represent sliding elements, for which the above-mentioned damping unit is suitable.
- the damping units mentioned at the beginning are provided, which dampen a movement of the sliding element into one or more end positions (end positions).
- at least one activator is attached either to the moving sliding element and / or to the guide device guiding this element, which activator interacts with the driver so that a braking force can be transmitted between the damping unit and the sliding element during damping.
- the damping unit can be combined with a retraction device so that it is automatically retracted into at least one end position. From the pamphlet DE 20 2005 014 050 U1 For example, a pull-out guide for furniture parts with a damping unit is known in which the opening movement is damped when the furniture guide is approached to a fully extended position.
- the pamphlet DE 20 2005 009 860 U1 shows a pull-out slide with a so-called touch-latch mechanism, through which the sliding element can be opened by briefly pressing the front panel.
- a draw-in damping is provided.
- a rest position of the front panel can be set by means of an adjustable stop.
- the movement behavior of a damped sliding element is dependent both on the damping properties of the linear damper of the damping unit used, in particular its damping force, and on the mass of the moving sliding element. If transmission elements are arranged between the driver and the linear damper, these also influence the damping behavior. Last but not least, personal preferences are also decisive as to whether stronger or weaker damping is desired for a sliding element. In order to be able to offer a damping unit on the part of the manufacturer that achieves satisfactory damping properties even with sliding elements with different weights and offers the user the option of adapting the damping properties to his own preferences, a damping device that can be adjusted with regard to the damping behavior is desirable.
- the pamphlet DE 10 2013 107 562 A1 describes a pull-out runner with cushioning, where cushioning paths of different lengths can be selected. With a longer damping path, larger masses can also be braked. However, such a change in the overall damping performance achieved is accompanied by a change in the damping path, which is not desirable in every application.
- a damping unit according to the invention is characterized in that the linear damper has a damping path that is longer than a displacement path of the driver and the linear damper has varying damping properties along the damping path.
- the coupling element thus makes it possible to use different sections of the damping path for damping the displacement movement of the driver. This is made possible by the fact that the damping path of the linear damper is longer than the displacement path of the driver. Because of the damping properties that vary along the damping path, the driver thus experiences different degrees of damping depending on the setting of the coupling element.
- a linear damper with cylinder and piston in which the cylinder is at least partially conical.
- the gap between the piston and the cylinder inner wall which changes with the position of the piston, leads to a variation in the damping force depending on the piston position and thus on the damping path.
- channels or projections can be formed in sections in a side wall of the cylinder of the linear damper, which are used to achieve damping properties that vary along the damping path.
- the coupling element fixes the cylinder or the piston rod of the linear damper in at least two different positions in a housing of the damping unit depending on its setting.
- the travel path of the driver corresponds to a different section of the damping path of the linear damper, the sections being displaced relative to one another, but being able to partially overlap.
- a first position for example, a section with less strong damping is used than in a second position.
- more than the two positions mentioned can also be provided as setting options.
- the linear damper can be installed in two different ways, either the cylinder or the piston rod with the mit slave is connected and accordingly the other part, piston rod or cylinder, then interacts with the coupling element.
- the coupling element can serve as a stop for the cylinder or the piston rod of the linear damper or be connected to the cylinder or the piston rod.
- the former is suitable if damping is only provided in one direction of movement and the linear damper has a spring in order to automatically move back into the starting position.
- the adjustability of the coupling element, through which the coupling element provides the at least two different positions of the cylinder or piston rod, can be implemented in different ways.
- the coupling element can be rotatable or pivotable in the housing in the at least two different positions.
- the coupling element can be guided in the housing in a longitudinally displaceable manner, whereby it can be locked in the at least two different positions.
- the locking can e.g. by means of a detent or a bayonet lock.
- the coupling element is coupled to an actuating lever, which is preferably accessible from the outside of the housing. In this way a tool-free and convenient adjustment of the damping effect is made possible.
- the operating lever can e.g. Be part of an adjusting element which is guided in a pivoting and / or sliding movement via at least one guide curve which is formed inside the housing.
- the adjustment element can be connected to the coupling element via a further lever on a side opposite the actuating lever.
- actuation of the actuating lever can be converted into a linear movement of the coupling element.
- the adjusting element is more preferably guided in a self-locking manner. In this way, the various positions into which the coupling element is pushed via the actuating lever are fixed by the linear damper when a force is applied to the coupling element.
- An additional locking device can be omitted.
- an adjusting screw can be provided in order to set the at least two different positions of the coupling element.
- a cabinet is first shown as an example of a piece of furniture 1 with a body 2 and two sliding elements 3, here sliding doors.
- the sliding elements 3 are guided in a horizontally displaceable manner via sliding guides 4.
- damping units 10 are provided, one of which can be seen in the area of the slightly opened, left sliding element 3.
- the damping unit 10 is arranged, for example, in the upper region of the furniture 1, it being possible for an additional or alternative arrangement to also take place in the lower region of the furniture 1.
- Fig. 2 shows the area around the damping unit 10 from FIG Fig. 1 in an enlarged detail view.
- the damping unit 10 is mounted with my housing 11 on the body 2 of the furniture 1.
- the damping unit 10 has a driver 12 which is linearly guided in the horizontal direction, that is to say in the sliding direction of the sliding element 3, and which interacts with an activator 5, which in the present case is arranged on the sliding element 3.
- the damping unit 10 can additionally be provided with a retraction function by means of which the driver 12 and thus the sliding element 3 are actively retracted into the end position with the aid of an energy store, usually a spring.
- a first embodiment of a damping unit 10 is shown, for example in the furniture 1 of Fig. 1 can be used.
- Fig. 3 shows a section of the damping unit 10 in an isometric illustration.
- the damping unit 10 has a housing 11, which is shown open in the present case in order to gain insight into the internal structure of the damping unit 10.
- a driver 12 is arranged displaceably in the longitudinal direction of the housing 11.
- a stationary guide curve 13 is formed in the housing 11.
- the driver 12 has two mutually movable driver arms 121 which, as shown, form a driver fork 122 into which the activator, not visible here, e.g. B. the activator 5 according to Fig. 2 can intervene.
- the driver 12 is coupled to a driver slide 14, wherein it can move in a direction perpendicular to the orientation of the stationary guide curve 13 in a guide curve 15 that moves along with the driver slide 14. This movement, like an angled end area in the stationary guide curve 13, enables the driver 12 to be tilted in order to be able to pick up or release the activator 5.
- the driver 12 moves in the longitudinal direction of the housing 11, however, the driver 12 and the driver slide 14 are coupled to one another.
- the cylinder 161 of the linear damper 16 is consequently moved with the driver 12 in the longitudinal direction.
- the basic principle according to the application can also be implemented with a linear damper in which not the cylinder 161, but rather the piston rod 162 of the damper 16 moves with the driver 12.
- the piston rod 162 is fixed in place relative to the housing 11 when the driver 12 moves.
- it is supported with a head 163 on a first stop 171 of a coupling element 17 which is inserted into the housing 11.
- a connection between the head 163 and the coupling element 17 can also be provided.
- the head 163 can be designed as a ball head, the ball snapping into an undercut recess on the coupling joint 17.
- FIG. 4a and b is the damping unit 10 according to Fig. 3 each shown in a plan view.
- the two Figures 4a and 4b differ in two different (on) positions of the coupling element 17.
- the in Figure 4a The position of the coupling element 17 shown corresponds to that in FIG Fig. 3 shown.
- the coupling element 17 is positioned in a first compartment 111 of the housing 11 which is formed transversely to the direction of displacement of the driver 12. In this position, the piston rod 162 rests with its head 163 on the first stop 171 or is connected with its head 163 to the coupling element 17 in the area of the stop 171.
- the coupling element 17 is shown in a second possible position in which the coupling element 17 is arranged in a second compartment 112 of the housing 111, this second compartment 112 being oriented essentially in the longitudinal direction of the displacement direction. In this position, the coupling element 17 provides a second stop 172 against which the head 163 of the piston rod 162 now rests or to which the head 163 is connected. With the driver 12 in the same position, in the second position of the coupling element 17, the piston rod 162 of the linear damper 16 is in the Figure 4b shown distance ⁇ x from the first position according to Figure 4a retracted.
- damping can take place over the entire displacement path of the driver 12, since the linear damper 16 has a damping path that is at least the distance ⁇ x longer than the displacement path of the driver 12.
- the linear damper 16 also has a damping behavior, where the damping force is not constant along the damping path. For example, it can be provided that the damping force is greater the further the piston rod 162 is pushed into the cylinder 161.
- FIGS Figures 7a to 7c One possible design of the linear damper 16, which shows such damping behavior, is shown in FIGS Figures 7a to 7c shown.
- the driver 12 experiences a greater damping force in every position when the coupling element 17 is in the second position according to FIG Figure 4b compared to the first position according to Figure 4a .
- the damping behavior in particular the damping force that the driver 12 experiences under otherwise identical conditions, can be adjusted here two levels can be set.
- a change between the two settings can take place, for example, by removing the coupling element 17 and reinserting it in the other position.
- the compartments 111, 112 can also be designed so that a change between the two setting positions can take place by pivoting the coupling element 17 without it having to be removed from the housing 11.
- the coupling element 17 then preferably latches in each of the two possible positions.
- a second embodiment of a damping unit 10 is shown.
- the figures each show a section of the damping unit 10 in an isometric illustration.
- a driver 12 with a driver fork 122 which is guided in a stationary guide curve 13 so as to be longitudinally displaceable.
- the driver 12 is connected to a driver carriage 14 which is displaced together with the driver 12 in the longitudinal direction.
- a cylinder 161 of a linear damper 16 is arranged in the driver slide 14.
- a piston rod 162 is connected to a coupling element 17 or rests against it.
- the coupling element 17 is guided displaceably in a guide 113 of the housing 11.
- the coupling element 17 can be moved in the direction of the longitudinal axis of the damping unit 10, that is to say in a direction parallel to the displacement path of the driver 12 and that of the driver slide 14.
- the coupling element 17 is guided axially in the direction of the piston rod 162.
- the piston rod 162 can rest on the coupling element 17 or be connected to it in a compressive and tensile manner.
- the piston rod 162 can in turn have a head 163 which is designed as a ball head, the ball snapping into an undercut recess on the coupling joint 17.
- Locking slots 114 are introduced along the guide 113 transversely to the longitudinal direction of the guide 113. In the present case, two such locking slots 114 are formed, but several such locking slots 114 can also be provided.
- a rectangular locking plate 174 is arranged on the coupling element 17, connected in a rotationally fixed manner to a tool holder 173.
- the tool holder 173 is designed in the manner of the head of an Allen screw.
- the locking plate 174 protrudes on two opposite sides over the outer circumference of the head of the tool holder 173.
- the housing 11 is again shown open. During operation, it is closed off by a housing plate or housing half placed on top, in which a guide for the coupling element 17 is formed analogously to guide 113. This also has correspondingly positioned locking slots analogous to the locking slots 114.
- FIG 5a a position of the coupling element 17 is shown in which the locking plate 174 is immersed in a rear locking slot, not visible in the figure.
- the coupling element 17 is thereby fixed with regard to its movement within the guide 113.
- the locking plate 174 can be rotated out of the corresponding locking slot, as shown in FIG Figure 5b is shown.
- the coupling element 17 is then free for a longitudinal movement in the direction of the guide 113. It can be brought into a front position corresponding to the Figures 5c and 5d is shown, in which with the same position of the driver 12, the piston rod 162 again by a distance ⁇ x from that in the Figures 5a and 5b positions shown of the coupling element 17 is extended.
- Fig. 5d the locking plate 174 is then immersed in the corresponding front locking slot 114 by rotating the coupling element 17 with the aid of the tool holder 173 and the coupling element 17 is thus fixed in the longitudinal direction.
- the bayonet lock-like coupling element 17 shown can also be adjusted via an adjusting screw, the piston rod 162 being moved relative to the cylinder 161 with the driver 12 in the same position by screwing in or unscrewing the adjusting screw.
- a screw locking device can be provided so that the adjusting screw is not adjusted passively and unintentionally. The setting with the aid of an adjusting screw enables a continuous adjustment of the damping properties within a range given by the adjustment range of the screw.
- the coupling element can be designed as a longitudinally displaceable slide which engages in two or more latching positions.
- Various basic positions of the piston rod 162 relative to the cylinder 161 can also be set by means of such a locking slide and the damping behavior can thus be varied in steps.
- FIGS. 5a to 5d show a further exemplary embodiment of a damping unit 10 in a detail in a top view.
- a housing 11 of the damping unit 10 is again shown open in order to be able to show the structure of the damping unit 10.
- a driver 12 which is guided in a longitudinally displaceable manner via a guide curve 13 and which is coupled to a linear damper 16 via a driver slide 14 in a manner not visible here, reference is made to the explanations Fig. 3 referenced.
- the linear damper 16 in turn has a cylinder 161 and a piston rod 162.
- a head 163 arranged at the end of the piston rod 162 is inserted or clipped into a coupling element 17, which is mounted in a guide 113 in the housing 11 so as to be displaceable in the direction of the piston rod 162.
- the coupling element 17 is thus similar to the embodiment of FIG Figures 5a to 5d axially displaceable, the damping effect of the linear damper 16 depending on the position of the coupling element 17 within the guide 113.
- the position of the coupling element 17 within the guide 113 can be set between two different positions by the user via an adjustment element 18 without tools.
- Figure 6a shows the adjusting element 18 in a first position and Figure 6b in a second position.
- Figure 6c Both the coupling element 17 and the adjusting element 18 are removed in order to be able to better represent the design of the housing 11 for guiding both the coupling element 17 and the adjusting element 18.
- the adjusting element 18 is designed in the manner of a two-sided lever which is connected to the coupling element 17 by a coupling lever 181 and in which an actuating lever 182 lying opposite is accessible from the outside as an actuating element through a housing opening.
- guide and locking pins 183 are formed on the adjustment element 18, which interact with guide cams 115 and locking recesses 116.
- the coupling lever 181 is rotatably connected to the coupling element 17.
- the end region of the coupling lever 181 is provided with an eye which is guided over a pin on the coupling element 17.
- the combination of the guide curve 115 and the connection to the coupling element 17, which in turn is guided, causes a combined sliding and pivoting movement of the adjusting element 18 when the actuating lever 182 is moved.
- the adjusting element 18 can be pivoted by actuating the actuating lever 182, but when a force is exerted by the coupling element 17 via the coupling lever 181, the adjusting element 18 blocks so that the set positions, in particular those in Figure 6b position of the adjusting element 18 shown is maintained.
- a piston 164 connected to the piston rod 162 and moving within the cylinder 161 can be seen.
- the interior of the cylinder 161 is filled with a viscous medium, usually a viscous liquid.
- a viscous medium usually a viscous liquid.
- the inner cylinder wall 165 is conical, which is shown exaggerated in the figures shown to illustrate the principle.
- the conicity of the cylinder inner wall 165 means that the gap remaining between the circumference of the piston 164 and the cylinder inner wall 165 is dependent on the position of the piston 164 within the cylinder 161.
- Fig. 8 shows, in the form of a diagram, schematically the dependency of a damping force D on a damping path x of a linear damper suitable for use in the damping unit, for example the one in FIG Figures 7a to 7c illustrated linear damper 16.
- the damping force D is given in percent (%) of a maximum damping force on a vertical axis of the diagram.
- the damping path x is shown in millimeters (mm) on a horizontal axis of the diagram.
- the course of the damping force D as a function of the damping path x is shown in the diagram by a damper curve 20.
- This damper curve 20 shows a linear course of the damper force D as a function of the damping path x.
- the damper curve 20 is, for example, that of the in FIGS Figures 7a to 7c illustrated linear damper 16.
- the position x indicates how far the piston rod 162 has moved out of the cylinder 161.
- the damping force D in the damping curve 20 is only 40% of the maximum value.
- the linear damper 16 When using the linear damper 16 in a damping unit that has a displacement path of its driver 12 of 60 mm, two different sections 21, 22 of the damping path can be used, the first section 21 having a damping path from the range of 0-60 mm and the second section 22 uses a damping path from the range of 20-80 mm.
- the damping force D within the first section 21 is greater than when the driver 12 is in the same position in the second section 22. A greater damping effect is accordingly established.
- the linear damper curve 20 shown as an example is monotonically falling. It goes without saying, however, that even with a damping force that is constant in sections, that is to say with a horizontally running damper curve 20, differently strong damping effects are achieved on average in sections 21 and 22 would. The same effect also occurs in the case of a damper curve that does not run linearly over the entire range or in certain areas, but instead rises or falls in some other way.

Description

Die Dämpfungseinheit weist einen linear geführten Mitnehmer auf, der mit einem direkt oder indirekt mit dem Schiebelement verbundenen Aktivator zusammenwirkt und der mit einem Lineardämpfer gekoppelt ist, wobei der Lineardämpfer einen Dämpfungsweg aufweist, der länger ist als ein Verschiebeweg des Mitnehmers.The invention relates to a damping unit for a sliding element, in particular a movable furniture part, a movable element of a household appliance or a sliding or folding door. The damping unit has a linearly guided driver which interacts with an activator connected directly or indirectly to the sliding element and which is coupled to a linear damper, the linear damper having a damping path that is longer than a displacement path of the driver.
Derartige Schiebeelemente sind beispielsweise bewegbare Möbelteile oder bewegbare Elemente eines Haushaltsgeräts, wie z. B. ein Schubkasten, auch als Schublade bezeichnet, ein Geräteträger o.ä., die üblicherweise an einer Führungsvorrichtung aus einem Möbelkorpus oder Haushaltsgerät herausziehbar gelagert sind. Eine solche Führungsvorrichtung wird auch als Auszugsvorrichtung bezeichnet. Als Schiebelemente sind ebenfalls verfahrbare Schiebetüren, Möbeltüren ebenso wie Wohnraumtüren, anzusehen, die über Führungselemente an einer Führungsschiene gelagert sind. Falttüren, bei denen zumindest ein Teil der Tür verfahrbar geführt ist, stellen ebenfalls Schiebeelemente dar, für die die oben genannte Dämpfungseinheit geeignet ist.Such sliding elements are, for example, movable furniture parts or movable elements of a household appliance, such as. B. a drawer, also referred to as a drawer, an equipment rack or the like, which are usually mounted on a guide device so that they can be pulled out of a furniture body or household appliance. Such a guide device is also referred to as a pull-out device. Movable sliding doors, furniture doors as well as living room doors, which are mounted on a guide rail via guide elements, are also to be regarded as sliding elements. Folding doors, in which at least a part of the door is movably guided, also represent sliding elements, for which the above-mentioned damping unit is suitable.
Zur komfortablen Betätigung solcher Schiebeelemente sind die eingangs genannten Dämpfungseinheiten vorgesehen, die eine Bewegung des Schiebeelements in eine oder mehrere Endlagen (Endpositionen) dämpfen. Zu diesem Zweck ist entweder am bewegten Schiebelement und/oder an der dieses Element führenden Führungsvorrichtung mindestens ein Aktivator angebracht, der mit dem Mitnehmer zusammenwirkt, so dass eine abbremsende Kraft beim Dämpfen zwischen der Dämpfungseinheit und dem Schiebeelement übertragen werden kann. Dabei kann die Dämpfungseinheit mit einer Einzugsvorrichtung kombiniert sein, so dass ein Selbsteinzug in mindestens eine Endlage erfolgt. Aus der Druckschrift
Die Druckschrift
Das Bewegungsverhalten eines gedämpften Schiebeelements ist sowohl von den Dämpfungseigenschaften des verwendeten Lineardämpfers der Dämpfungseinheit, insbesondere seiner Dämpfungskraft, abhängig, als auch von der Masse des bewegten Schiebeelements. Falls zwischen dem Mitnehmer und dem Lineardämpfer Übersetzungselemente angeordnet sind, beeinflussen diese ebenfalls das Dämpfungsverhalten. Nicht zuletzt sind zudem persönliche Vorlieben entscheidend, ob eine stärkere oder schwächere Dämpfung für ein Schiebeelement gewünscht ist. Um von Seiten des Herstellers eine Dämpfungseinheit anbieten zu können, die auch bei Schiebeelementen mit unterschiedlichem Gewicht zufriedenstellende Dämpfungseigenschaften erzielt und auf Seiten des Benutzers die Möglichkeit bietet, die Dämpfungseigenschaften den eigenen Vorlieben anzupassen, ist eine in Hinblick auf das Dämpfungsverhalten einstellbare Dämpfungsvorrichtung wünschenswert.The movement behavior of a damped sliding element is dependent both on the damping properties of the linear damper of the damping unit used, in particular its damping force, and on the mass of the moving sliding element. If transmission elements are arranged between the driver and the linear damper, these also influence the damping behavior. Last but not least, personal preferences are also decisive as to whether stronger or weaker damping is desired for a sliding element. In order to be able to offer a damping unit on the part of the manufacturer that achieves satisfactory damping properties even with sliding elements with different weights and offers the user the option of adapting the damping properties to his own preferences, a damping device that can be adjusted with regard to the damping behavior is desirable.

Es ist daher eine Aufgabe der vorliegenden Erfindung, eine Dämpfungseinheit der eingangs genannten Art zu schaffen, bei der das Dämpfungsverhalten auf einfache Weise unabhängig von der Länge des Dämpfungswegs einstellbar ist.It is therefore an object of the present invention to create a damping unit of the type mentioned at the outset, in which the damping behavior can be adjusted in a simple manner independently of the length of the damping path.
Diese Aufgabe wird durch eine Dämpfungseinheit mit den Merkmalen des unabhängigen Anspruchs gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This object is achieved by a damping unit with the features of the independent claim. Advantageous refinements and developments are specified in the dependent claims.
Eine erfindungsgemäße Dämpfungseinheit zeichnet sich dadurch aus, dass der Lineardämpfer einen Dämpfungsweg aufweist, der länger ist als ein Verschiebeweg des Mitnehmers und der Lineardämpfer entlang des Dämpfungswegs variierende Dämpfungseigenschaften aufweist. Es ist ein einstellbares Koppelelement vorhanden, das dem Verschiebeweg des Mitnehmers wahlweise unterschiedliche Abschnitte des Dämpfungsweges zuordnet.A damping unit according to the invention is characterized in that the linear damper has a damping path that is longer than a displacement path of the driver and the linear damper has varying damping properties along the damping path. There is an adjustable coupling element that optionally assigns different sections of the damping path to the displacement path of the driver.
Das Koppelelement ermöglicht es somit, unterschiedliche Abschnitte des Dämpfungswegs für die Dämpfung der Verschiebebewegung des Mitnehmers einzusetzen. Möglich wird dieses dadurch, dass der Dämpfungsweg des Lineardämpfers länger ist als der Verschiebeweg des Mitnehmers. Aufgrund der entlang des Dämpfungswegs variierenden Dämpfungseigenschaften erfährt der Mitnehmer damit abhängig von der Einstellung des Koppelelements unterschiedlich starke Dämpfungen.The coupling element thus makes it possible to use different sections of the damping path for damping the displacement movement of the driver. This is made possible by the fact that the damping path of the linear damper is longer than the displacement path of the driver. Because of the damping properties that vary along the damping path, the driver thus experiences different degrees of damping depending on the setting of the coupling element.
Um entlang des Dämpfungswegs variierende Dämpfungseigenschaften zu erzielen, wird ein Lineardämpfer mit Zylinder und Kolben eingesetzt, bei dem der Zylinder zumindest bereichsweise konisch ausgebildet ist. Das sich so mit der Stellung des Kolbens verändernde Spaltmaß zwischen dem Kolben und der Zylinderinnenwand führt zu eine Variation der Dämpfungskraft in Abhängigkeit von der Kolbenstellung und damit von dem Dämpfungsweg.In order to achieve damping properties that vary along the damping path, a linear damper with cylinder and piston is used, in which the cylinder is at least partially conical. The gap between the piston and the cylinder inner wall, which changes with the position of the piston, leads to a variation in the damping force depending on the piston position and thus on the damping path.
Zusätzlich können in einer Seitenwand des Zylinders des Lineardämpfers abschnittsweise Kanäle oder Vorsprünge ausgebildet sein, die dazu verwendet werden, entlang des Dämpfungswegs variierende Dämpfungseigenschaften zu erzielen.In addition, channels or projections can be formed in sections in a side wall of the cylinder of the linear damper, which are used to achieve damping properties that vary along the damping path.
Um den Verschiebeweg des Mitnehmers wahlweise unterschiedliche Abschnitte des Dämpfungsweges zuzuordnen, legt das Koppelelement den Zylinder oder die Kolbenstange des Lineardämpfers abhängig von seiner Einstellung in mindestens zwei unterschiedlichen Positionen in einem Gehäuse der Dämpfungseinheit fest. In jeder Position entspricht der Verfahrweg des Mitnehmers einem anderen Abschnitt des Dämpfungswegs des Lineardämpfers, wobei die Abschnitte gegeneinander verschoben sind, aber teilweise überlappen können. In einer ersten Stellung wird so beispielsweise ein in Mittel weniger stark dämpfender Abschnitt genutzt als in einer zweiten Stellung. Es können selbstverständlich auch mehr als die beiden genannten Positionen als Einstellmöglichkeiten vorgesehen sein.In order to optionally assign different sections of the damping path to the displacement path of the driver, the coupling element fixes the cylinder or the piston rod of the linear damper in at least two different positions in a housing of the damping unit depending on its setting. In each position, the travel path of the driver corresponds to a different section of the damping path of the linear damper, the sections being displaced relative to one another, but being able to partially overlap. In a first position, for example, a section with less strong damping is used than in a second position. Of course, more than the two positions mentioned can also be provided as setting options.
Grundsätzlich kann der Lineardämpfer auf zwei unterschiedliche Arten eingebaut sein, wobei entweder der Zylinder oder die Kolbenstange mit dem Mit nehmer verbunden ist und entsprechend der andere Teil, Kolbenstange oder Zylinder, dann mit dem Koppelelement zusammenwirkt.Basically, the linear damper can be installed in two different ways, either the cylinder or the piston rod with the mit slave is connected and accordingly the other part, piston rod or cylinder, then interacts with the coupling element.
Das Koppelelement kann als ein Anschlag für den Zylinder oder die Kolbenstange des Lineardämpfers dienen oder mit dem Zylinder oder der Kolbenstange verbunden sein. Ersteres eignet sich, wenn eine Dämpfung nur in eine Bewegungsrichtung vorgesehen ist und der Lineardämpfer eine Feder aufweist, um selbsttätig wieder in die Ausgangsstellung zu verfahren.The coupling element can serve as a stop for the cylinder or the piston rod of the linear damper or be connected to the cylinder or the piston rod. The former is suitable if damping is only provided in one direction of movement and the linear damper has a spring in order to automatically move back into the starting position.
Die Einstellbarkeit des Koppelelements, durch die das Koppelelement die mindestens zwei verschiedenen Positionen von Zylinder oder Kolbenstange bereitstellt, kann auf verschiedene Weisen umgesetzt sein.The adjustability of the coupling element, through which the coupling element provides the at least two different positions of the cylinder or piston rod, can be implemented in different ways.
Beispielsweise kann das Koppelelement in dem Gehäuse in die mindestens zwei unterschiedlichen Positionen drehbar oder schwenkbar sein. Alternativ kann das Koppelelement in dem Gehäuse längsverschieblich geführt sein, wobei es in den mindestens zwei unterschiedlichen Positionen arretiert werden kann. Die Arretierung kann z.B. mithilfe einer Rastung oder eines Bajonettverschlusses erfolgen.For example, the coupling element can be rotatable or pivotable in the housing in the at least two different positions. Alternatively, the coupling element can be guided in the housing in a longitudinally displaceable manner, whereby it can be locked in the at least two different positions. The locking can e.g. by means of a detent or a bayonet lock.
In einer vorteilhaften Ausgestaltung der Dämpfungseinheit ist das Koppelelement mit einem Betätigungshebel gekoppelt, der bevorzugt von außen am Gehäuse zugänglich ist. Auf diese Weise wird eine werkzeuglose und bequeme Verstellung der Dämpfungswirkung ermöglicht.In an advantageous embodiment of the damping unit, the coupling element is coupled to an actuating lever, which is preferably accessible from the outside of the housing. In this way a tool-free and convenient adjustment of the damping effect is made possible.
Dabei kann der Betätigungshebel z.B. Teil eines Verstellelements sein, das über mindestens eine Führungskurve, die innerhalb des Gehäuses ausgebildet ist, in einer Schwenk- und/oder Schiebebewegung geführt ist. Das Verstellelement kann an einer dem Betätigungshebel gegenüberliegenden Seite über einen weiteren Hebel mit dem Koppelelement verbunden sein. Durch eine kombinierte Schwenk- und Schiebebewegung kann eine Betätigung des Betätigungshebels in eine lineare Bewegung des Koppelelements umgesetzt werden. Weiter bevorzugt ist das Verstellelement selbsthemmend geführt. Auf diese Weise sind die verschiedenen Positionen, in die das Koppelelement über den Betätigungshebel geschoben wird, bei einer Krafteinwirkung auf das Koppelelement durch den Lineardämpfer fixiert. Eine zusätzlich zu betätigende Arretiervorrichtung kann entfallen.The operating lever can e.g. Be part of an adjusting element which is guided in a pivoting and / or sliding movement via at least one guide curve which is formed inside the housing. The adjustment element can be connected to the coupling element via a further lever on a side opposite the actuating lever. By means of a combined pivoting and sliding movement, actuation of the actuating lever can be converted into a linear movement of the coupling element. The adjusting element is more preferably guided in a self-locking manner. In this way, the various positions into which the coupling element is pushed via the actuating lever are fixed by the linear damper when a force is applied to the coupling element. An additional locking device can be omitted.
In einer weiteren Alternative kann eine Stellschraube vorgesehen sein, um die mindestens zwei unterschiedlichen Positionen des Koppelelements einzustellen.In a further alternative, an adjusting screw can be provided in order to set the at least two different positions of the coupling element.

Beim Schließen des Schiebeelements 3 greift der Aktivator 5 in den Mitnehmer 12 ein, der daraufhin die Schließbewegung bis zum geschlossenen Zustand des Schiebeelements 3 dämpft. Dabei kann die Dämpfungseinheit 10 zusätzlich mit einer Einzugsfunktion versehen sein, durch die der Mitnehmer 12 und damit das Schiebeelement 3 aktiv mit Hilfe eines Kraftspeichers, üblicherweise einer Feder, in die Endlage eingezogen wird.When the sliding

Der Mitnehmer 12 ist mit einem Mitnehmerschlitten 14 gekoppelt, wobei er sich in einer Richtung senkrecht zur Ausrichtung der stationären Führungskurve 13 in einer mitbewegten Führungskurve 15 am Mitnehmerschlitten 14 bewegen kann. Diese Bewegung ermöglicht, ebenso wie ein abgewinkelter Endbereich in der stationären Führungskurve 13, ein Verkippen des Mitnehmers 12, um den Aktivator 5 aufnehmen bzw. freigeben zu können. Bei einer Bewegung des Mitnehmers 12 in Längsrichtung des Gehäuses 11 sind der Mitnehmer 12 und der Mitnehmerschlitten 14 jedoch miteinander gekoppelt.The
In einer Aussparung des Mitnehmerschlittens 14 ist ein Lineardämpfer 16 mit einem Zylinder 161 und einer Kolbenstange 162, die im Inneren des Zylinders 161 mit einem Kolben 164 verbunden ist, angeordnet. Bei diesem Ausführungsbeispiel der Dämpfungseinheit 10 wird folglich der Zylinder 161 des Lineardämpfers 16 mit dem Mitnehmer 12 in Längsrichtung verfahren. Es versteht sich, dass das anmeldungsgemäße Grundprinzip auch mit einem Lineardämpfer umgesetzt werden kann, bei dem sich nicht der Zylinder 161, sondern die Kolbenstange 162 des Dämpfers 16 mit dem Mitnehmer 12 bewegt. Beim dargestellten Ausführungsbeispiel ist die Kolbenstange 162 bei Bewegung des Mitnehmers 12 ortsfest relativ zum Gehäuse 11 festgelegt. Zu diesem Zweck stützt sie sich mit einem Kopf 163 an einem ersten Anschlag 171 eines Koppelelements 17 ab, das in das Gehäuse 11 eingesetzt ist. Anstelle eines Anschlags kann auch eine Verbindung des Kopfes 163 und des Koppelelements 17 vorgesehen sein. Beispielsweise kann der Kopf 163 als ein Kugelkopf ausgebildet sein, wobei die Kugel in eine hinterschnittene Mulde am Koppelgelenk 17 einschnappt.A

In beiden Stellungen des Koppelelements 17 kann eine Dämpfung über den gesamten Verschiebeweg des Mitnehmers 12 erfolgen, da der Lineardämpfer 16 einen Dämpfungsweg aufweist, der um mindestens den Abstand Δx länger ist als der Verschiebeweg des Mitnehmers 12. Der Lineardämpfer 16 weist zudem ein Dämpfungsverhalten auf, bei dem die Dämpfungskraft entlang des Dämpfungswegs nicht konstant ist. Beispielsweise kann vorgesehen sein, dass die Dämpfungskraft um so größer ist, je weiter die Kolbenstange 162 in den Zylinder 161 eingeschoben ist. Eine mögliche Ausgestaltung des Lineardämpfers 16, der ein derartiges Dämpfungsverhalten zeigt, ist in den

Bei dieser Ausgestaltung ist das Koppelelement 17 in einer Führung 113 des Gehäuses 11 verschiebbar geführt. Innerhalb der Führung 113 kann das Koppelelement 17 in Richtung der Längsachse der Dämpfungseinheit 10, also in einer Richtung parallel zum Verschiebeweg des Mitnehmers 12 und der des Mitnehmerschlittens 14 bewegt werden. Mit anderen Worten erfolgt die Führung des Koppelelements 17 axial in Richtung der Kolbenstange 162. Je nachdem, ob eine Dämpfung in eine oder beide Bewegungsrichtungen des Mitnehmers gewünscht ist, kann die Kolbenstange 162 am Koppelelement 17 anliegen oder mit diesem druck- und zugbelastbar verbunden sein. Beispielsweise kann die Kolbenstange 162 wiederum einen Kopf 163 aufweisen, der als ein Kugelkopf ausgebildet ist, wobei die Kugel in einer hinterschnittenen Mulde am Koppelgelenk 17 einschnappt.In this embodiment, the
Entlang der Führung 113 sind quer zur Längsrichtung der Führung 113 Arretierschlitze 114 eingebracht. Vorliegend sind zwei derartige Arretierschlitze 114 ausgebildet, es können jedoch auch mehrere derartiger Arretierschlitze 114 vorgesehen sein. Am Koppelelement 17 ist, drehfest verbunden mit einer Werkzeugaufnahme 173, eine rechteckförmige Arretierplatte 174 angeordnet. Die Werkzeugaufnahme 173 ist nach Art eines Kopfes einer Inbusschraube ausgebildet. Die Arretierplatte 174 steht zu zwei gegenüberliegenden Seiten über den äußeren Umfang des Kopfes der Werkzeugaufnahme 173 hervor.Locking

Auch über einen derartigen rastenden Schieber können verschiedene Grundstellungen der Kolbenstange 162 relativ zum Zylinder 161 eingestellt werden und das Dämpfungsverhalten somit in Stufen variiert werden.In a further possible embodiment, the coupling element can be designed as a longitudinally displaceable slide which engages in two or more latching positions.

Ein Gehäuse 11 der Dämpfungseinheit 10 ist wiederum geöffnet wiedergegeben, um den Aufbau der Dämpfungseinheit 10 darstellen zu können. Bezüglich des Grundaufbaus, insbesondere im Hinblick auf einen Mitnehmer 12, der über eine Führungskurve 13 längsverschieblich geführt ist und der in hier nicht sichtbarer Weise über einen Mitnehmerschlitten 14 mit einem Lineardämpfer 16 gekoppelt ist, wird auf die Erläuterungen zu
Der Lineardämpfer 16 weist wiederum einen Zylinder 161 und eine Kolbenstange 162 auf. Ein am Ende der Kolbenstange 162 angeordneter Kopf 163 ist in ein Koppelelement 17 eingelegt oder eingeclipst, das in einer Führung 113 im Gehäuse 11 in Richtung der Kolbenstange 162 verschiebbar gelagert ist. Das Koppelelement 17 ist somit ähnlich wie in dem Ausführungsbeispiel der

Das Verstellelement 18 ist nach Art eines zweiseitigen Hebels ausgebildet, der mit einem Koppelhebel 181 mit dem Koppelelement 17 verbunden ist und bei dem ein gegenüber liegender Betätigungshebel 182 als Betätigungselement durch eine Gehäuseöffnung von außen zugänglich ist.The adjusting
In einem mittleren Bereich sind Führungs- und Arretierstifte 183 am Verstellelement 18 ausgebildet, die mit Führungskurven 115 und Arretiermulden 116 wechselwirken. In seinem Endbereich ist der Koppelhebel 181 drehbar mit dem Koppelelement 17 verbunden. Im dargestellten Beispiel ist der Endbereich des Koppelhebels 181 mit einem Auge versehen, das über einen Stift am Koppelelement 17 geführt ist. Die Kombination der Führungskurve 115 und der Verbindung zum seinerseits geführten Koppelelement 17 bedingt eine kombinierte Schiebe- und Schwenkbewegung des Verstellelements 18 bei Bewegung des Betätigungshebels 182.In a central area, guide and locking
Durch ein Eingreifen der Führungs- und Arretierstifte 183 in die Arretiermulden 116 ist zudem eine Selbsthemmung des Verstellelements 18 gegeben.

Bei Bewegung des Kolbens 164 strömt das viskose Medium zwischen dem Kolben und einer Zylinderinnenwand 165 vorbei, was zur Dämpfung der Bewegung des Kolbens 164 und der Kolbenstange 162 relativ zum Zylinder 161 führt.In the sectional images, a
Als Besonderheit ist die Zylinderinnenwand 165 konisch ausgebildet, was in den gezeigten Figuren zur Veranschaulichung des Prinzips übertrieben dargestellt ist.

Bei vollständig ausgefahrener Kolbenstange 162 im Bild der
Es wird darauf hingewiesen, dass zusätzlich zu der konisch ausgebildeten Zylinderinnenwand 165 auch entlang der Zylinderinnenwand 165 verlaufende Kanäle oder Vorsprünge, die in verschiedenen Bereichen in verschiedener Anzahl oder mit verschiedenen Querschnitt vorhanden sind, eine positionsabhängige Variation der Dämpfungseigenschaften erzielt werden kann.It should be noted that in addition to the conical cylinder

Der Dämpfungsweg x ist in Millimetern (mm) auf einer horizontalen Achse des Diagramms dargestellt. Der Verlauf der Dämpfungskraft D In Abhängigkeit von dem Dämpfungsweg x ist durch eine Dämpferkurve 20 in dem Diagramm eingezeichnet. Diese Dämpferkurve 20 zeigt einen linearen Verlauf der Dämpferkraft D abhängig vom Dämpfungsweg x.The damping force D is given in percent (%) of a maximum damping force on a vertical axis of the diagram. The damping path x is shown in millimeters (mm) on a horizontal axis of the diagram. The course of the damping force D as a function of the damping path x is shown in the diagram by a

Beim Einsatz des Lineardämpfers 16 in einer Dämpfungseinheit, die einen Verschiebeweg ihres Mitnehmers 12 von 60 mm aufweist, können somit zwei verschiedene Abschnitte 21, 22 des Dämpfungswegs genutzt werden, wobei der erste Abschnitt 21 einen Dämpfungsweg aus dem Bereich von 0-60 mm und der zweite Abschnitt 22 einen Dämpfungsweg aus dem Bereich von 20 - 80 mm nutzt. Die beiden Abschnitte 21, 22 sind also um einen Abstand Δx = 20mm voneinander beabstandet, der durch verschiedene Einstellungen des Koppelelements 17 erzielt wird. In jedem Punkt des Verschiebewegs des Mitnehmers 12 ist die Dämpfungskraft D innerhalb des ersten Abschnitts 21 größer als bei gleicher Stellung des Mitnehmers 12 im zweiten Abschnitt 22. Entsprechend stellt sich eine größere Dämpfungswirkung ein.When using the
Die beispielhaft dargestellte linear verlaufende Dämpferkurve 20 ist monoton fallend. Es versteht sich, dass jedoch auch bei einer in Abschnitten konstanten Dämpfungskraft, also bei waagerecht verlaufender Dämpferkurve 20 im Mittel unterschiedlich starke Dämpfungswirkungen in den Abschnitten 21 und 22 erzielt würden. Ein gleicher Effekt tritt auch ein bei einer über den gesamten Bereich oder bereichsweise nicht linear, sondern anderweitig steigend oder fallend verlaufenden Dämpferkurve ein.The
