Definitions
- the invention relates to a spring base for in particular a mattress of a sleeping, sitting or lying furniture according to the preamble of claim 1.
- the underslung mentioned here is an elastic and / or resilient support for mattresses or similar upholstery of beds, berths, couches, armchairs or the like.
- the invention has for its object to provide a spring base for a particular mattress of a sleeping, sitting or lying furniture, which ensures improved spring characteristics and a more uniform support of the mattress.
- a suspension to solve this problem has the features of claim 1. Accordingly, it is envisaged that the spring arms are guided around the bottom and bottom of the spring strips at least some pairs of spring bars up around. While it was previously common practice that the spring arms led straight up to receive the mattress be, or that the spring arms between the individual spring strips of a pair of spring strips are passed through up to a common spring plate, the invention now goes another way by the spring arms between the spring strips of each pair of spring strips first led down and then outside the spring strips of a each spring bar pairs are guided around upwards for receiving the mattress. As a result, relatively long spring arms can be created, which has a large spring travel over the spring travel largely constant spring characteristic.
- the support points of the support elements move apart with the mattress base, whereby the support of the mattress is distributed uniformly over its surface.
- the support members each have a suspension which extends between the spring strips of a spring strip pair and the suspension in the region of the respective pair of spring strips at least two spring arms are assigned. With a suspension several spring arms can be connected to a spring strip pair simultaneously. In addition, by the suspension takes place a coupling of the spring arms to the respective suspension.
- the suspension of the support elements has at least two supports, which act from above on the spring strip pair for fixing the support elements on the spring strips. In this case, a support is assigned for each spring bar of the respective spring bar pair.
- the supports can be fastened to spring strips having different flexural strengths in their cross section, wherein the spring strips are rotatable along their longitudinal axis to change the spring properties of the support elements. Due to a non-circular cross-sectional shape or due to a specific choice of material, the spring strips may have varying moments of resistance depending on the orientation (rotation about the longitudinal axis). Depending on their relative position to the support elements or to the supports, the spring strips have different bending characteristics, whereby the support elements receive different spring properties. This allows a further individualization of the suspension behavior of the spring suspension.
- At least one pair of spring strips at least one spring arm is guided upwards around each spring strip.
- a plurality, preferably two spring arms are guided around each spring strip at least some pairs of spring strips upwards. It becomes the spring effect the support elements distributed more homogeneously over the entire mattress surface and increases the spring action of each support element.
- the support elements each have a suspension which extends downwardly between the spring strips of a spring strip pair and the suspension in the region of the respective spring strip pair at least two spring arms are assigned.
- the suspension between the spring strips of a pair of spring strips preferably extends to below the spring strips.
- the spring arms then extend in the opposite direction transversely to the spring strips to the outside. With a suspension several spring arms can be connected to a spring strip pair simultaneously. In addition, by the suspension takes place a coupling of the spring arms to the respective suspension.
- a plurality of, preferably two support plates are assigned to an outer end of the respective spring arm.
- these support plates assigned to the ends of the respective spring arm serve as a support surface for the mattress.
- the spring arms are connected to the support plates height adjustable with the suspension of the support elements.
- the spring properties of the support elements can be changed individually. For example, a selected area of the mattress can be increased by adjusting the support elements.
- the height adjustment of the support plate, which are in fixed relation to the spring arms, is done by converting the spring arms on the suspension.
- the spring arms are connected to the suspension such that the spring arms, preferably equally all spring arms of a suspension, can be connected in several positions with the suspension. These positions correspond to different heights of the support plates relative to the spring strips.
- the suspension of the support elements has at least two supports, which are latched from above onto the spring strip pair for fixing the support elements on the spring strips.
- a support is assigned for each spring bar of the respective spring bar pair.
- a further embodiment of the invention provides that the connection between the spring arms and the suspension is formed by a flexible connecting profile piece.
- This connecting profile piece is located between the at least two spring arms and the suspension. Due to the special nature of the connecting profile piece, the force acting on a spring arm, transmitted in a special way to the other spring arm or on the suspension. For example, can be achieved by an appropriate choice of the connecting profile piece that the movement of the spring arms is coupled. This allows a flexible and individual design of the support elements and thus the spring characteristics of the spring base.
- the spring strips with a non-circular cross section is assigned in each case a ring which is rotatably mounted in the suspension.
- This ring creates a connection or a transition between the non-circular cross-section of the respective spring bar and the suspension.
- a rotation of the spring bar is made possible with its associated ring with respect to the suspensions.
- the respective ring can be manually or motor driven adjustable.
- the spring strips 10 and the pairs of female pairs 11 are mounted with opposite ends on two parallel longitudinal bars, not shown.
- the longitudinal bars extend in the longitudinal direction of the spring base or the mattress arranged thereon.
- the spring strips 10 and the spring strip pairs 11 extend transversely to the longitudinal beams.
- the longitudinal beams are interconnected by transverse bars, not shown, so that the longitudinal beams with the cross beams form a rigid, rectangular frame, for example a bed frame.
- the spring strips 10 and the spring strip pairs 11 are at their opposite ends in the Fig. 4 and 5 illustrated bearing body 12 connected to the longitudinal beams.
- the bearing body 12 serve to elastically or hingedly connect the ends of the spring strips 10 and the spring strip pairs with the longitudinal beams.
- the ends of the spring strips 10 and female pairs 11 can also be attached to the longitudinal members with any differently configured bearing bodies. It is conceivable in the spring base according to the invention but also a rigid connection of the ends of the spring strips 10 and the female pairs 11 with the longitudinal beams.
- the spring strips 10 of the spring strip pairs 11 are connected to one another in the region between the longitudinal bars. This additional connection is made by supporting elements 13, 50, 60, 70, 80th
- the Fig. 1 to 6 show various embodiments of fully or partially elastic or semi-rigid and after a compression in the original shape automatically returning support members 13, 50, 60, 70, 80.
- the support elements 13, 50, 60, 70, 80 couple the relevant spring strips 10 of a spring strip pair 11 together.
- the spring strips 10 and the female pairs 11 thus act in the manner of a continuous over the entire surface of the spring base. Local deflections of the spring strips 10 and the spring bar pairs 11 and thereby caused discontinuous course of the suspension with localized depressions are avoided in this way.
- the support elements 13, 50, 60, 70, 80 cause local deformations of individual spring strips 10 and female pairs 11, in particular vertical deflection of the spring strips 10 and the pairs of female pairs 11, 11 are transferred to adjacent female connectors 10 and female pairs. Adjacent spring strips 10 or adjacent spring strip pairs 11 thus take part in the deflection of individual spring strips 10 or spring strip pairs 11, preferably only partially. This results in a continuous, continuous transition to adjacent spring strips 10 and female pairs 11 and thus evenly distributed on the surface of the spring support deformation of the support elements 13, 50, 60, 70, 80 in particular vertical loads individual spring strips 10 and female pairs and / or slats 10.
- FIG. 1 illustrated support member 13 has four support plate 14, two spring arms 15, a suspension 16 and two supports 17.
- the entire support element 13 is in one piece and consists of an elastic material, preferably plastic. It can also be made from any other flexible material.
- Each spring strip pair 11 has a plurality of support elements 13.
- the entire spring base has a plurality of preferably identical support elements 13.
- the support elements 13 are fastened to the spring strip pairs 11, and preferably between the spring strips 10 of a spring strip pair 11.
- the attachment is such that the support members 13 either fixed at certain locations on the spring strips 10 of the spring strip pair 11 or slidably mounted on the spring strips 10 of the pairs of female pairs 11 are fastened.
- the two supports 17 of the support element 13 are each brought into contact with the upper side 19 of the two spring strips 10 of a spring strip pair 11. Due to the elongated curved shape of the supports 17, these fit in a form-fitting manner to the upper side 19 of the spring strips 10 of the spring strip pair 11.
- the supports 17 surround the top 19 of the spring strips 10 of the spring strip pair 11 partially.
- the attachment of the supports 17 at the top 19 is carried out either via a latching connection, a clamp connection or similar connection mechanisms.
- the two supports 17 are connected via the suspension 16, which extends between the spring strips 10 of the spring strip pair 11.
- the suspension 16 can either continue the curved shape of the two supports 17, in which the two supports 17 are joined together in a U-shape or they can be formed as a web extending between the two spring strips 10 of the spring strip pair 11 down.
- the connection between the supports 17 and the suspension 16 is such that the two supports 17 are flexibly connected to the suspension 16, preferably merge into one another.
- the spring arms 15 are also attached.
- the two spring arms 15 extending starting from the suspension 16 and the shape of the curved support 17 continuing between the two spring strips 10 of the respective spring strip pair 11 in opposite directions and transverse to the spring strips 10 under the spring strips 10 of the spring strip pair 11 around outwards; similar in form to the Greek letter ⁇ (omega).
- the two spring arms 15 have a curved shape, whereby the spring arms 15 extend from below the pair of spring strips 11 in opposite directions outwards and then upwards, so that they extend beyond the tops 19 of the spring strips 10.
- the spring arms 15 are thereby guided around the two parallel spring strips 10 from the underside of the pair of spring strips 11 in a mirror-image course outside.
- the spring arms 15 are attached to the suspension 16 so that they are flexible up and down movable.
- the two are in opposite directions extending spring arms 15 independently movable.
- the two spring arms 15 are also coupled to one another via their common suspension 16 such that their spring movements can correspond, in particular the spring movements are at least partially transmitted.
- Each of the spring arms 15 is divided or branches into two spring arm 18, which in turn extend obliquely upward from each other.
- Each spring arm 18 is integrally connected at its free end to one of the support plates 14.
- the support plates 14 at each end of the four spring arm 18 are flat plates which are aligned parallel to the plane spanned by the spring strips 10 and female pairs 11 and are at a distance above this level.
- the four support plates 14 are the same shape, but can also be designed differently.
- the spring arm 18 are attached to a longitudinal side 21 of the support plate 14. The longitudinal side 21 opposite the free longitudinal side facing the spring strip pair 11. However, the support plates 14 can also take any other orientation.
- the surfaces 22 of the individual support plates 14 are such that they can accommodate the mattress.
- the underside of the mattress enters with the surfaces 22 of the support plate 14 in contact. Thereby, the weight of the mattress is transferred to the surface 22 and thus to the support plate 14 and to the entire support member 13.
- Characterized in that four support plates 14 are assigned to the support member in the present embodiment the force acting on the individual support plate 14 weight of the mattress is reduced.
- the force acting on the surface 22 of the support plate 14 weight of the mattress is uniformly transmitted to the spring arms 15 of the support members 13.
- the spring arms 15 counteract the weight of the mattress in a resilient manner. Depending on the weight of the mattress or after loading the mattress and after relieving the mattress, the spring arms 15 move up and down.
- the support elements move back to their original position. Because the present exemplary embodiment of the support element 13 has four support plates 14, each having a spring arm part 18, the support element 13 can absorb or counteract local stresses on the mattress. The transmitted by the weight of the mattress on the spring arms 15 spring force continues to be transmitted to the spring strips 10 of the pair of spring strips 11. This results in a light, cross-section suspension of the entire suspension, resulting in increased sleeping comfort. According to personal wishes and requirements, the support elements 13 can be moved freely on the spring strips 10 of the spring strip pair 11.
- Fig. 2 is a side view of the support member 13 is shown. So that the support elements 13 can be fixed on the spring strips 10 of the spring strip pair 11 and do not slip unintentionally along the spring strips 10, the support member 13 can be fixed at fixed positions. These fasteners serve latching means 23, which are located on the undersides 24 of the two supports 17.
- the locking means 23 are formed as hooks which extend parallel to the spring strips 10 along the support 17. For attachment of the supports 17 with the spring strips 10, the locking means 23 are brought with their counterparts, not shown, on the spring strips 10 in connection. This connection can be such that the support elements 13 are assigned to a fixed location on the spring strips 10 or remain displaceable along the spring strips 10.
- the locking means 23 prevent not only a slight slippage along the spring strips, but also a rotation of the support members 13 to the spring strips 10 of the spring strip pair 11 around.
- each spring arm 15 and the U-shaped lower part 36 of the suspension 16 each have an additional web 37.
- the spring force acting on the spring arms 15 is additionally transmitted to the U-shaped lower part 36 of the suspension 16.
- the two spring arms 15 with each other communicate, ie the spring action of a spring arm 15 is transmitted to the other spring arm 15.

- equivalent components as in the embodiment in the Fig. 1 and Fig. 2 provided with identical reference numerals.
- connection profile piece 25 which connects the spring arms 15 to the suspension 16 and thereby gives the support member 13 particular spring properties.
- the connecting profile piece 25 is integrally connected to the lower part 36 of the suspension 16 on the one hand and the two spring arms 15 joining together.
- the spring arms 15 and the suspension 16 form a shape that is similar to that of the inverted capital letter "T".
- the connecting profile piece 25 acquires special spring properties.
- the spring arms 15 act together resiliently. In a one-sided load of the support member 50 by a single spring arm 15, this burden on the connection profile piece 25 on the other arm 15 acts.
- connection profile piece 25 thus the spring effects of the two spring arms 15 are coupled together.
- embodiments of the connecting profile piece 25 are also conceivable which counteract a coupling of the two spring arms 15.
- the connecting profile piece 25 thus, the spring action of the entire support member 50 can be preset. It is conceivable, for example, that the support elements 50 in the head, foot or lumbar region have different connection profile pieces 25, since these areas have a different load.

Description
Die Erfindung betrifft eine Unterfederung für insbesondere eine Matratze eines Schlaf-, Sitz- oder Liegemöbels gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a spring base for in particular a mattress of a sleeping, sitting or lying furniture according to the preamble of claim 1.
Bei der hier angesprochenen Unterfederung handelt es sich um ein elastisches und/oder federndes Auflager für Matratzen oder ähnliche Polsterungen von Betten, Schlafkojen, Liegen, Sesseln oder dergleichen.The underslung mentioned here is an elastic and / or resilient support for mattresses or similar upholstery of beds, berths, couches, armchairs or the like.
Es sind verschiedene Unterfederungen der oben genannten Art bekannt. Die Unterfederungen unterscheiden sich im Wesentlichen in ihrer Federcharakteristik. So offenbaren die Dokumente
Der Erfindung liegt die Aufgabe zugrunde, eine Unterfederung für insbesondere eine Matratze eines Schlaf-, Sitz- oder Liegemöbels zu schaffen, die eine verbesserte Federcharakteristik und eine gleichmäßigere Abstützung der Matratze gewährleistet.The invention has for its object to provide a spring base for a particular mattress of a sleeping, sitting or lying furniture, which ensures improved spring characteristics and a more uniform support of the mattress.
Eine Unterfederung zur Lösung dieser Aufgabe weist die Merkmale des Anspruchs 1 auf. Demnach ist es vorgesehen, dass die Federarme unten und außen um die Federleisten mindestens einiger Federleistenpaare herum nach oben geführt sind. Während es bisher üblich war, dass die Federarme direkt nach oben zur Aufnahme der Matratze geführt werden, oder dass die Federarme zwischen den einzelnen Federleisten eines Federleistenpaars hindurch nach oben zu einem gemeinsamen Federteller geführt werden, geht die Erfindung nun einen anderen Weg, indem die Federarme zwischen den Federleisten eines jeden Federleistenpaars zunächst nach unten geführt und dann außen um die Federleisten eines jeden Federleistenpaars herum nach oben zur Aufnahme der Matratze geführt werden. Dadurch können relativ lange Federarme geschaffen werden, die über einen großen Federweg bei über den Federweg weitestgehend gleichbleibender Federcharakteristik verfügt. Außerdem rücken die Auflagepunkte der Stützelemente mit der Matratzenunterseite auseinander, wodurch die Abstützung der Matratze gleichmäßiger über ihre Fläche verteilt wird. Es ist außerdem vorgesehen, dass die Stützelemente jeweils eine Aufhängung aufweisen, die sich zwischen den Federleisten eines Federleistenpaars erstreckt und der Aufhängung im Bereich des jeweiligen Federleistenpaares mindestens zwei Federarme zugeordnet sind. Mit einer Aufhängung können gleichzeitig mehrere Federarme an einem Federleistenpaar verbunden werden. Außerdem findet durch die Aufhängung eine Kopplung der Federarme an der jeweiligen Aufhängung statt. Weiter ist es erfindungsgemäß vorgesehen, dass die Aufhängung der Stützelemente mindestens zwei Auflager aufweist, die von oben auf das Federleistenpaar zur Fixierung der Stützelemente auf die Federleisten wirken. Dabei ist für jede Federleiste des betreffenden Federleistenpaar ein Auflager zugeordnet. Dadurch, dass die Auflager auf zwei nebeneinanderliegenden Federleisten eines Federleistenpaars aufliegen, wird die Kraft, die von der Matratze auf die Auflageteller und die Federarme wirkt, auf das Federleistenpaar übertragen. Gemäß einem weiteren Merkmal ist es vorgesehen, dass die Auflager an in ihrem Querschnitt unterschiedliche Biegefestigkeiten aufweisenden Federleisten befestigbar sind, wobei die Federleisten entlang ihrer Längsachse zur Veränderung der Federeigenschaften der Stützelemente verdrehbar sind. Die Federleisten können aufgrund einer unrunden Querschnittsform oder aufgrund einer bestimmten Materialwahl je nach Orientierung (Verdrehung um die Längsachse) sich ändernde Widerstandsmomente aufweisen. Abhängig von ihrer relativen Position zu den Stützelementen bzw. zu den Auflagern besitzen die Federleisten verschiedene Biegecharakteristiken, wodurch die Stützelemente unterschiedlich Federeigenschaften erhalten. Dies ermöglicht eine weitere Individualisierung des Federungsverhaltens der Unterfederung.A suspension to solve this problem has the features of claim 1. Accordingly, it is envisaged that the spring arms are guided around the bottom and bottom of the spring strips at least some pairs of spring bars up around. While it was previously common practice that the spring arms led straight up to receive the mattress be, or that the spring arms between the individual spring strips of a pair of spring strips are passed through up to a common spring plate, the invention now goes another way by the spring arms between the spring strips of each pair of spring strips first led down and then outside the spring strips of a each spring bar pairs are guided around upwards for receiving the mattress. As a result, relatively long spring arms can be created, which has a large spring travel over the spring travel largely constant spring characteristic. In addition, the support points of the support elements move apart with the mattress base, whereby the support of the mattress is distributed uniformly over its surface. It is also contemplated that the support members each have a suspension which extends between the spring strips of a spring strip pair and the suspension in the region of the respective pair of spring strips at least two spring arms are assigned. With a suspension several spring arms can be connected to a spring strip pair simultaneously. In addition, by the suspension takes place a coupling of the spring arms to the respective suspension. Further, it is inventively provided that the suspension of the support elements has at least two supports, which act from above on the spring strip pair for fixing the support elements on the spring strips. In this case, a support is assigned for each spring bar of the respective spring bar pair. Due to the fact that the supports rest on two adjacent spring strips of a pair of spring strips, the force which acts from the mattress on the support plates and the spring arms is transferred to the pair of spring strips. According to a further feature, it is provided that the supports can be fastened to spring strips having different flexural strengths in their cross section, wherein the spring strips are rotatable along their longitudinal axis to change the spring properties of the support elements. Due to a non-circular cross-sectional shape or due to a specific choice of material, the spring strips may have varying moments of resistance depending on the orientation (rotation about the longitudinal axis). Depending on their relative position to the support elements or to the supports, the spring strips have different bending characteristics, whereby the support elements receive different spring properties. This allows a further individualization of the suspension behavior of the spring suspension.
Es ist des Weiteren vorgesehen, dass außen um jede Federleiste herum mindestens einiger Federleistenpaare wenigstens ein Federarm nach oben geführt ist. Es ist jedoch auch denkbar, dass mehrere, vorzugsweise zwei Federarme um jede Federleiste mindestens einiger Federleistenpaare nach oben geführt werden. Es wird so die Federwirkung der Stützelemente homogener über die gesamte Matratzenfläche verteilt und die Federwirkung jedes einzelnen Stützelements erhöht.It is furthermore provided that at least one pair of spring strips at least one spring arm is guided upwards around each spring strip. However, it is also conceivable that a plurality, preferably two spring arms are guided around each spring strip at least some pairs of spring strips upwards. It becomes the spring effect the support elements distributed more homogeneously over the entire mattress surface and increases the spring action of each support element.
Bei einer bevorzugten Ausgestaltung der erfindungsgemäßen Unterfederung ist es vorgesehen, dass die Stützelemente jeweils eine Aufhängung aufweisen, die sich zwischen den Federleisten eines Federleistenpaars nach unten erstreckt und der Aufhängung im Bereich des jeweiligen Federleistenpaares mindestens zwei Federarme zugeordnet sind. Dabei erstreckt sich die Aufhängung zwischen den Federleisten eines Federleistenpaars vorzugsweise bis unterhalb der Federleisten. Von einem unteren Teil der Aufhängung erstrecken sich dann die Federarme in entgegengesetzter Richtung quer zu den Federleisten nach außen. Mit einer Aufhängung können gleichzeitig mehrere Federarme an einem Federleistenpaar verbunden werden. Außerdem findet durch die Aufhängung eine Kopplung der Federarme an der jeweiligen Aufhängung statt.In a preferred embodiment of the invention, it is provided that the support elements each have a suspension which extends downwardly between the spring strips of a spring strip pair and the suspension in the region of the respective spring strip pair at least two spring arms are assigned. In this case, the suspension between the spring strips of a pair of spring strips preferably extends to below the spring strips. From a lower part of the suspension, the spring arms then extend in the opposite direction transversely to the spring strips to the outside. With a suspension several spring arms can be connected to a spring strip pair simultaneously. In addition, by the suspension takes place a coupling of the spring arms to the respective suspension.
Gemäß einer anderen vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, dass einem äußeren Ende des jeweiligen Federarms mehrere, vorzugsweise zwei Auflageteller zugeordnet sind. Dazu kann es vorgesehen sein, dass diese den Enden des jeweiligen Federarms zugeordneten Auflageteller als Auflagefläche für die Matratze dienen. Indem jedem Federarm mehrere Auflageteller zugeordnet sind, wird eine besonders gleichmäßige Abstützung der Matratze durch die Auflagerteller geschaffen.According to another advantageous embodiment of the invention, it is provided that a plurality of, preferably two support plates are assigned to an outer end of the respective spring arm. For this purpose, it may be provided that these support plates assigned to the ends of the respective spring arm serve as a support surface for the mattress. By each spring arm associated with several support plates, a particularly uniform support of the mattress is created by the support plates.
Erfindungsgemäß ist es außerdem vorgesehen, dass die Federarme mit den Auflagetellern höhenverstellbar mit der Aufhängung der Stützelemente verbunden sind. Dadurch können die Federeigenschaften der Stützelemente individuell verändert werden. So kann zum Beispiel ein ausgewählter Bereich der Matratze durch Verstellung der Stützelemente erhöht werden. Die Höhenverstellung der Auflageteller, welche in festem Bezug zu den Federarmen stehen, erfolgt durch ein Umsetzen der Federarme an der Aufhängung. Die Federarme sind derart mit der Aufhängung verbunden, dass die Federarme, vorzugsweise gleichermaßen alle Federarme einer Aufhängung, in mehreren Positionen mit der Aufhängung verbunden werden können. Diese Positionen entsprechen verschiedenen Höhen der Auflageteller relativ zu den Federleisten.According to the invention, it is also provided that the spring arms are connected to the support plates height adjustable with the suspension of the support elements. As a result, the spring properties of the support elements can be changed individually. For example, a selected area of the mattress can be increased by adjusting the support elements. The height adjustment of the support plate, which are in fixed relation to the spring arms, is done by converting the spring arms on the suspension. The spring arms are connected to the suspension such that the spring arms, preferably equally all spring arms of a suspension, can be connected in several positions with the suspension. These positions correspond to different heights of the support plates relative to the spring strips.
Gemäß einer Weiterbildung der Unterfederung ist es vorgesehen, dass die Aufhängung der Stützelemente mindestens zwei Auflager aufweist, die von oben auf das Federleistenpaar zur Fixierung der Stützelemente auf die Federleisten aufgerastet sind. Dabei ist für jede Federleiste des betreffenden Federleistenpaar ein Auflager zugeordnet. Durch das Aufrasten von oben werden die Auflager bei Belastung der Stützelemente auf die Federleisten gedrückt und so auf demselben sicher gehalten. Durch dieses Aufrasten der Auflager auf den Federleisten lassen sich diese Auflager und damit die gesamten Stützelemente entlang der Federleisten verschieben. Die Auflager können aber auch frei auf den Federleisten liegen. Dadurch, dass die Auflager auf zwei nebeneinanderliegenden Federleisten eines Federleistenpaars aufliegen, wird die Kraft, die von der Matratze auf die Auflageteller und die Federarme wirkt, auf das Federleistenpaar übertragen.According to one embodiment of the spring base, it is provided that the suspension of the support elements has at least two supports, which are latched from above onto the spring strip pair for fixing the support elements on the spring strips. In this case, a support is assigned for each spring bar of the respective spring bar pair. By Aufrasten from above the supports are under load of the support elements on the Pressed spring strips and so kept safe on the same. This Aufrasten the supports on the spring strips can be these supports and thus move the entire support elements along the spring strips. But the supports can also lie freely on the spring strips. Due to the fact that the supports rest on two adjacent spring strips of a pair of spring strips, the force which acts from the mattress on the support plates and the spring arms is transferred to the pair of spring strips.
Eine weitere Ausgestaltung der Erfindung sieht es vor, dass die Verbindung zwischen den Federarmen und der Aufhängung von einem flexiblen Verbindungsprofilstück gebildet ist. Dieses Verbindungsprofilstück befindet sich zwischen den mindestens zwei Federarmen und der Aufhängung. Durch die besondere Beschaffenheit des Verbindungsprofilstücks wird die Kraft, die auf einen Federarm wirkt, in besonderer Weise auf den anderen Federarm bzw. auf die Aufhängung übertragen. So kann beispielsweise durch eine entsprechende Wahl des Verbindungsprofilstücks erreicht werden, dass die Bewegung der Federarme gekoppelt ist. Dies ermöglicht eine flexible und individuelle Ausgestaltung der Stützelemente und somit der Federeigenschaften der Unterfederung.A further embodiment of the invention provides that the connection between the spring arms and the suspension is formed by a flexible connecting profile piece. This connecting profile piece is located between the at least two spring arms and the suspension. Due to the special nature of the connecting profile piece, the force acting on a spring arm, transmitted in a special way to the other spring arm or on the suspension. For example, can be achieved by an appropriate choice of the connecting profile piece that the movement of the spring arms is coupled. This allows a flexible and individual design of the support elements and thus the spring characteristics of the spring base.
Außerdem ist es erfindungsgemäß vorgesehen, dass den Federleisten mit einem unrunden Querschnitt jeweils ein Ring zugeordnet ist, der drehbar in der Aufhängung gelagert ist. Dieser Ring schafft eine Verbindung bzw. einen Übergang zwischen dem unrunden Querschnitt der jeweiligen Federleiste und der Aufhängung. Dadurch wird ein Verdrehen der Federleiste mit dem ihr zugeordnetem Ring in Bezug zu den Aufhängungen ermöglicht. Dem Grad der Verdrehung entsprechend ändert sich das Biegeverhalten der Federleiste und somit die Federwirkung der Stützelemente. Der jeweilige Ring kann manuell oder motorisch angetrieben verstellbar sein.In addition, it is inventively provided that the spring strips with a non-circular cross section is assigned in each case a ring which is rotatably mounted in the suspension. This ring creates a connection or a transition between the non-circular cross-section of the respective spring bar and the suspension. As a result, a rotation of the spring bar is made possible with its associated ring with respect to the suspensions. According to the degree of rotation, the bending behavior of the spring bar and thus the spring action of the support elements changes. The respective ring can be manually or motor driven adjustable.
Es ist für die Unterfederung des Weiteren erfindungsgemäß vorgesehen, dass der jeder Federleiste zugeordnete Ring in mindestens zwei, vorzugsweise vier verschiedene Federwirkungen aufweisende Positionen individuell verdrehbar ist. Durch ein gleichermaßen erfolgendes Verdrehen der den Federleisten des jeweiligen Federleistenpaares zugeordneten Ring kann die Elastizität aller Stützelemente des Federleistenpaares gleichermaßen verändert werden. Durch einzelnes, individuelles Verdrehen des nur einer Federleiste eines jeweiligen Federleistenpaares zugeordneten Rings können die Federeigenschaften der Stützelemente dieses Federleistenpaares voneinander abweichen. Dies ermöglicht eine individuelle und personenspezifische Optimierung des Komforts der Unterfederung.

The spring base has a plurality of, preferably identically designed spring strips 10. Two spring strips 10 are each a spring strip pair 11th grouped. The spring base has a plurality of preferably equally trained pairs of spring strips 11. The individual spring strips 10 as well as the pair of
Die Federleisten 10 bzw. die Federleistenpaare 11 sind mit gegenüberliegenden Enden an zwei parallelen, nicht dargestellten Längsholmen gelagert. Die Längsholme erstrecken sich in Längsrichtung der Unterfederung bzw. der darauf angeordneten Matratze. Demgegenüber verlaufen die Federleisten 10 bzw. die Federleistenpaare 11 quer zu den Längsholmen. Vorzugsweise sind die Längsholme durch nicht gezeigte Querholme miteinander verbunden, so dass die Längsholme mit den Querholmen einen starren, rechteckigen Rahmen, beispielsweise einen Bettrahmen, bilden. Die Federleisten 10 bzw. die Federleistenpaare 11 sind an ihren gegenüberliegenden Enden durch in den
Erfindungsgemäß sind die Federleisten 10 der Federleistenpaare 11 im Bereich zwischen den Längsholmen miteinander verbunden. Diese zusätzliche Verbindung erfolgt durch Stützelemente 13, 50, 60, 70 ,80. Die
Das in
Jedes Federleistenpaar 11 weist mehrere Stützelemente 13 auf. Somit verfügt die gesamte Unterfederung über eine Vielzahl von vorzugsweise gleichen Stützelementen 13.Each
Die Stützelemente 13 werden an den Federleistenpaaren 11 befestigt, und zwar bevorzugt zwischen den Federleisten 10 eines Federleistenpaars 11. Die Befestigung erfolgt derart, dass die Stützelemente 13 entweder fest an bestimmten Stellen auf den Federleisten 10 des Federleistenpaars 11 oder gleitend verschiebbar auf den Federleisten 10 der Federleistenpaare 11 befestigt werden. Dabei werden die beiden Auflager 17 des Stützelements 13 jeweils mit der Oberseite 19 der beiden Federleisten 10 eines Federleistenpaares 11 in Kontakt gebracht. Durch die länglich gekrümmte Form der Auflager 17 passen sich diese formschlüssig an die Oberseite 19 der Federleisten 10 des Federleistenpaars 11 an. Somit umschließen die Auflager 17 die Oberseite 19 der Federleisten 10 des Federleistenpaars 11 teilweise. Die Befestigung der Auflager 17 an der Oberseite 19 erfolgt entweder über eine Rastverbindung, eine Klemmverbindung oder ähnliche Verbindungsmechanismen.The
Die beiden Auflager 17 sind über die Aufhängung 16, die sich zwischen den Federleisten 10 des Federleistenpaars 11 erstreckt, verbunden. Die Aufhängung 16 kann dabei entweder die geschwungene Form der beiden Auflager 17 fortführen, in dem die beiden Auflager 17 in einer U-Form zusammenfügt werden oder sie können als Steg ausgebildet sein, der sich zwischen den beiden Federleisten 10 des Federleistenpaars 11 nach unten erstreckt. Die Verbindung zwischen den Auflagern 17 und der Aufhängung 16 ist derart, dass die beiden Auflager 17 flexibel mit der Aufhängung 16 in Verbindung stehen, vorzugsweise ineinander übergehen.The two
An der Aufhängung 16 sind außerdem die Federarme 15 befestigt. Die beiden Federarme 15 erstrecken sich ausgehend von der Aufhängung 16 und die Form der geschwungenen Auflager 17 fortführend zwischen den beiden Federleisten 10 des betreffenden Federleistenpaares 11 in entgegengesetzte Richtungen und quer zu den Federleisten 10 unter den Federleisten 10 des Federleistenpaars 11 herum nach außen; in der Form dem griechischen Buchstaben Ω (Omega) ähnlich. Dabei verfügen die beiden Federarme 15 über eine gebogene Form, wodurch sich die Federarme 15 von unterhalb des Federleistenpaars 11 in entgegengesetzte Richtungen nach außen und dann nach oben erstrecken, so dass sie bis über die Oberseiten 19 der Federleisten 10 reichen. Die Federarme 15 sind dadurch von der Unterseite des Federleistenpaares 11 in einem spiegelbildlichen Verlauf außen um die beiden parallelen Federleisten 10 herumgeführt. Die Federarme 15 sind derart an der Aufhängung 16 befestigt, dass sie flexibel auf- und abbewegbar sind. Dabei sind die beiden sich in entgegengesetzte Richtungen erstreckenden Federarme 15 unabhängig voneinander bewegbar. Die beiden Federarme 15 sind jedoch über ihre gemeinsame Aufhängung 16 auch derart miteinander gekoppelt, dass ihre Federbewegungen korrespondieren können, insbesondere die Federbewegungen sich zumindest teilweise übertragen.On the
Jeder der Federarme 15 teilt sich auf bzw. verzweigt sich in zwei Federarmteile 18, die sich wiederum schräg voneinander nach oben erstrecken. Jedes Federarmteil 18 ist an seinem freien Ende mit einem der Auflageteller 14 einstückig verbunden.Each of the
Die Auflageteller 14 an jedem Ende der vier Federarmteile 18 stellen flache Platten dar, die parallel zu der von den Federleisten 10 bzw. Federleistenpaare 11 aufgespannten Ebene ausgerichtet sind und sich mit Abstand über dieser Ebene befinden. Die vier Auflageteller 14 sind formgleich, können jedoch auch unterschiedlich beschaffen sein. Zur Material- bzw. Gewichtsreduzierung weisen die Auflageteller 14 Löcher 20 auf. Die Federarmteile 18 sind an einer Längsseite 21 der Auflageteller 14 befestigt. Die der Längsseite 21 gegenüberliegende freie Längsseite ist dem Federleistenpaar 11 zugewandt. Die Auflageteller 14 können jedoch auch jede mögliche andere Orientierung einnehmen.The
Die Oberflächen 22 der einzelnen Auflageteller 14 sind derart beschaffen, dass sie die Matratze aufnehmen können. Die Unterseite der Matratze tritt dabei mit den Oberflächen 22 der Auflageteller 14 in Kontakt. Dadurch wird die Gewichtskraft der Matratze auf die Oberfläche 22 und somit auf die Auflageteller 14 bzw. auf das gesamte Stützelement 13 übertragen. Dadurch, dass im vorliegenden Ausführungsbeispiel vier Auflageteller 14 dem Stützelement zugeordnet sind, reduziert sich die auf den einzelnen Auflageteller 14 wirkende Gewichtskraft der Matratze. Die auf die Oberfläche 22 der Auflageteller 14 wirkende Gewichtskraft der Matratze wird gleichmäßig auf die Federarme 15 der Stützelemente 13 übertragen. Die Federarme 15 wirken der Gewichtskraft der Matratze in einer federnden Art und Weise entgegen. Je nach Gewicht der Matratze bzw. nach Belastung der Matratze und nach Entlastung der Matratze bewegen sich die Federarme 15 auf und ab. Wirkt keine Kraft auf die Auflageteller 14, bewegen sich die Stützelemente zurück in ihre Ausgangsposition. Dadurch, dass das vorliegende Ausführungsbeispiel des Stützelements 13 vier Auflageteller 14 mit jeweils einem Federarmteil 18 aufweist, kann das Stützelement 13 lokale Belastungen auf der Matratze abfedern bzw. entgegenwirken. Die durch die Gewichtskraft der Matratze auf die Federarme 15 übertragene Federkraft überträgt sich weiter auf die Federleisten 10 des Federleistenpaars 11. Dadurch kommt es zu einer leichten, bereichsübergreifenden Federung der gesamten Unterfederung, was zu einem erhöhten Schlafkomfort führt. Den persönlichen Wünschen und Anforderungen entsprechend können die Stützelemente 13 frei auf den Federleisten 10 des Federleistenpaars 11 verschoben werden.The

Dazu werden die beiden Federarme 15 mit den Auflagetellern 14 relativ zu dem Auflager 63 herab- bzw. heraufgesetzt.

Somit ist das Stützelement 70 in drei diskrete Positionen höhenverstellbar.

Um die Federwirkung der Unterfederung zu ändern, können die Federeigenschaften der einzelnen Federleisten 10 verändert werden. Dazu weisen die Federleisten 10 beispielsweise in Längsrichtung unterschiedliche Materialien mit unterschiedlicher Biegecharakteristik auf. Im hier dargestellten Ausführungsbeispiel besitzen die Federleisten 10 einen unrunden Querschnitt 33. Dieser unrunde Querschnitt ist im gezeigten Ausführungsbeispiel elliptisch mit einer langen Achse 82 und einer kurzen Achse 83. Durch diesen unrunden Querschnitt 33 der Federleisten 10 lässt sich ihre Biegefestigkeit durch Verdrehung um ihre Längsachse 34 ändern. Je nachdem, wie die Federleisten 10 um ihre Längsachse 34 verdreht sind, weisen die Federleisten 10 ein weiches oder hartes Biegeverhalten auf.In order to change the spring action of the spring base, the spring characteristics of the individual spring strips 10 can be changed. For this purpose, the spring strips 10, for example, in the longitudinal direction of different materials with different bending characteristics. In the embodiment shown here, the spring strips 10 have a
Sind die unrunden Federleisten 10 entlang ihrer Längsachse 34 so verdreht, dass die lange Achse 82 der Federleisten 10 senkrecht zu der von dem Federleistenpaar 11 aufgespannten Ebene ausgerichtet ist, weisen die Federleisten 10 bei Belastung eine große Biegefestigkeit auf. Wenn hingegen die unrunden Federleisten 10 entlang ihrer Längsachse 34 derart verdreht sind, dass die kurze Achse 83 der Federleisten 10 senkrecht zu der von dem Federleistenpaar 11 aufgespannten Ebene ausgerichtet ist, schwingen die Federleisten 10 bei Belastung relativ weich.If the non-round spring strips 10 are rotated along their
Damit die einen unrunden Querschnitt 33 aufweisenden Federleisten 10 bzw. Federleistenpaare 11 relativ zu dem Stützelement 80 verdreht werden können, ist jeder Federleiste 10 des Federleistenpaars 11 im Bereich jedes Stützelements 80 ein Ring 31 zugeordnet. Die Ringe 31 weisen jeweils eine unrunde Aufnahme 35 auf, mit der die unrunden Federleisten 10 formschlüssig aufgenommen werden können. Außerdem weisen die Ringe 31 jeweils ein nicht dargestelltes rundes Verbindungsteil auf, die formschlüssig, um die Längsachse 34 drehbar in Aussparungen des Auflagers 84 des Stützelements 80 gelagert sind. Das Auflager 84 ist derart ausgestaltet, dass es die runden Verbindungsteile der Ringe 31 umschließt.So that a

Somit lassen sich über das Verdrehen der Federleisten 10 nur bestimmter Federleistenpaare 11 verschiedene Federwirkungen für den Kopf-, Lenden- und/oder Fußbereich einstellen.
