Description

Die Erfindung betrifft ein Bett nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a bed according to the preamble of claim 1.

Aus der DE 202 00 975 U1 ist ein höhenverstellbares Bett mit einer in der Höhe verstellbaren Auflagefläche und einer Mehrzahl von die Auflagefläche umgebenden Rahmenteilen bekannt. Die Auflagefläche liegt auf einem Tragteil auf, das über einen Anschlussflansch geführt in der Höhe verstellbar ist. Der Anschlussflansch weist eine Mehrzahl von Löchern auf, in die eine ortsfest angeordnete Raste eingreifen kann. Nachteilig an dem bekannten Bett ist, dass eine Führung vorgesehen sein muss und die Mittel zur Höheneinstellung zusätzlich an dem Bett angebracht werden müssen, was den Material- und Kostenaufwand erhöht.From the DE 202 00 975 U1 a height-adjustable bed with a height-adjustable support surface and a plurality of frame parts surrounding the support surface is known. The support surface rests on a supporting part, the height of which is adjustable via a connecting flange. The connecting flange has a plurality of holes into which a stationary catch can engage. The disadvantage of the known bed is that a guide must be provided and the means for height adjustment must also be attached to the bed, which increases the material and cost.

Aus der US 2 234 562 A ist ein höhenverstellbares Bett mit einer Auflagefläche und mit einer Mehrzahl von Rahmenteilen bekannt. Die Rahmenteile bilden zusammen einen Gitterrahmen, wobei zwischen einer oberen Verbindungsstange und einer unteren Verbindungsstange parallel und in einem Abstand zueinander verlaufende Streben vorgesehen sind. Als Streben sind zum einen Begrenzungsstreben vorgesehen, die eine Mehrzahl von Nuten aufweisen, so dass die Auflagefläche unter Eingreifen in die Nuten in der Höhe verstellbar angeordnet sein kann. Zum anderen sind Begrenzungsstreben ausgebildet, die in Längsrichtung in einer Mehrzahl der Begrenzungsstrebe verlaufende Schrägflächen aufweisen, die stufig voneinander abgesetzt sind. Diese sind ebenfalls dazu geeignet, die Auflagefläche in einer bestimmten Höhe, nämlich in Höhe des Absatzes zu halten.From the US 2,234,562 A A height-adjustable bed with a support surface and a plurality of frame parts is known. The frame parts together form a lattice frame, with an upper connecting rod and a lower connecting rod struts running parallel and at a distance from one another are provided. On the one hand, limiting struts are provided as struts, which have a plurality of grooves, so that the support surface can be arranged to be adjustable in height while engaging in the grooves. On the other hand, limiting struts are designed which have inclined surfaces running in the longitudinal direction in a majority of the limiting strut and which are set apart from one another in steps. These are also suitable for keeping the support surface at a certain height, namely at the height of the heel.

Aus der DE 203 07 464 U1 ist keine Höhen- und Tiefenbegrenzung für eine Auflagefläche bekannt.From the DE 203 07 464 U1 There are no known height and depth limitations for a support surface.

Aus der DE 10 2017 120 085 A1 ist ein Kinderbett mit einer Auflagefläche und einer Mehrzahl von Rahmenteilen bekannt. Die Rahmenteile weisen jeweils parallel zueinander verlaufende Streben auf, so dass ein Gitterrahmen gebildet ist. Ein vorderes Rahmenteil weist an gegenüberliegenden Endbereichen eine Begrenzungsstrebe mit einer oberen Verdickung auf. Hierdurch wird verhindert, dass das vordere Rahmenteil nicht vollständig abgesenkt werden kann.From the DE 10 2017 120 085 A1 A children's bed with a support surface and a plurality of frame parts is known. The frame parts each have struts that run parallel to one another, so that a grid frame is formed. A front frame part has a limiting strut with an upper thickening at opposite end regions. This prevents the front frame part from being able to be lowered completely.

Aufgabe der vorliegenden Erfindung ist es daher, die Höheneinstellung eines Bettes auf einfache und sichere Weise zu verbessern.The object of the present invention is therefore to improve the height adjustment of a bed in a simple and safe manner.

Zur Lösung dieser Aufgabe weist die Erfindung die Merkmale des Patentanspruchs 1 auf.To solve this problem, the invention has the features of patent claim 1.

Der besondere Vorteil der Erfindung besteht darin, dass auf einfache und sichere Weise eine Höheneinstellung einer Auflagefläche des Bettes ermöglicht wird. Die Höheneinstellung kann zur Höhenbegrenzung und/oder zur Tiefenbegrenzung der vorzugsweise eine Matratze aufnehmenden Auflagefläche dienen. Das vordere Rahmenteil kann in der Tiefe begrenzt werden, so dass ein Ausfallschutz bei einer Öffnungsstellung des vorderen Rahmenteiles vorliegt, wenn es sich insbesondere um ein Kinderbett handelt. Grundgedanke der Erfindung ist es, dass Bestandteile des Bettes selbst, nämlich Streben des als Gitterbett ausgebildeten Bettes als Mittel zur Höhenein- und/oder Höhenverstellung bzw. Höhenbegrenzung genutzt werden. Bestimmte vertikal verlaufende Streben der Rahmenteile des Bettes weisen als Begrenzungsstrebe en eine Verdickung auf, derart, dass ein stirnseitiges Ende dieser Verdickung als Anschlagfläche dient, beispielsweise für die Auflagefläche oder einer zusätzlichen Klemmeinrichtung. Das Erscheinungsbild des Bettes wird hierdurch nicht beeinträchtigt. Die Verdickung weist lediglich eine größere Quererstreckung auf als ein Restabschnitt derselben Strebe. Die Quererstreckung der Verdickung an dem Ende desselben ist so groß gewählt, dass das Ende dieser Verdickung eine entsprechende Anschlagfläche bildet.The particular advantage of the invention is that the height of a support surface of the bed can be adjusted in a simple and safe manner. The height adjustment can be used to limit the height and/or to Serve to limit the depth of the support surface, which preferably accommodates a mattress. The front frame part can be limited in depth so that there is protection against failure when the front frame part is in the open position, especially if it is a child's bed. The basic idea of the invention is that components of the bed itself, namely struts of the bed designed as a crib, are used as a means for height adjustment and/or height limitation. Certain vertical struts of the frame parts of the bed have a thickening as limiting struts, such that a front end of this thickening serves as a stop surface, for example for the support surface or an additional clamping device. This does not affect the appearance of the bed. The thickening merely has a larger transverse extent than a remaining section of the same strut. The transverse extent of the thickening at the end thereof is chosen to be so large that the end of this thickening forms a corresponding stop surface.

Nach der Erfindung weist die Begrenzungsstrebe in einem oberen Bereich derselben eine ober Verdickung auf mit einer an einem unteren Ende derselben angeordneten Anschlagfläche. Hierdurch wird eine Höhenbegrenzung für die Auflagefläche geschaffen einerseits. Wenn die Begrenzungsstrebe mit der oberen Verdickung an dem vorderen Rahmenteil angeordnet ist, wird hierdurch eine Tiefenbegrenzung für das vordere Rahmenteil gebildet, so dass die maximale Öffnungsstellung des vorderen Rahmenteils, beispielsweise eines Schiebegitters, festgelegt ist. Ein unerwünschtes Herausfallen des Kindes im Öffnungszustand des vorderen Rahmenteils kann somit entgegengewirkt werden.According to the invention, the limiting strut has an upper thickening in an upper region thereof with a stop surface arranged at a lower end thereof. On the one hand, this creates a height limit for the support surface. If the limiting strut with the upper thickening is arranged on the front frame part, this creates a depth limit for the front frame part, so that the maximum opening position of the front frame part, for example a sliding grille, is fixed. An undesirable fall out of the child when the front frame part is open can thus be counteracted.

Nach der Erfindung weist die Begrenzungsstrebe in einem unteren Bereich derselben eine untere Verdickung auf mit einer an einem oberen Ende derselben angeordneten Anschlagfläche. Hierdurch wird eine Tiefenbegrenzung der Auflagefläche bewirkt. Kommt die Auflagefläche mit einer Randkante zur Anlage an die Anschlagfläche der Verdickung, befindet sich die Auflagefläche in der tiefsten Stellung. Bei Vorliegen einer oberen Verdickung und einer unteren Verdickung der Begrenzungsstrebe kann somit die Auflagefläche zwischen der Höhenbegrenzung und der Tiefenbegrenzung in der Höhe verstellt bzw. eingestellt werden, wenn zusätzlich die Klemmeinrichtung an der mindestens eine Strebe unter Festlegung der Auflagefläche in der Höhe befestigt ist.According to the invention, the limiting strut has a lower thickening in a lower region thereof with a stop surface arranged at an upper end thereof. This limits the depth of the Support surface causes. If the support surface comes into contact with an edge against the stop surface of the thickening, the support surface is in the lowest position. If there is an upper thickening and a lower thickening of the limiting strut, the height of the support surface between the height limit and the depth limit can be adjusted or adjusted if the clamping device is also attached to the at least one strut to fix the height of the support surface.

Nach einer Weiterbildung der Erfindung weist die Verdickung eine größere Quererstreckung in Richtung quer zu der langgestreckten Begrenzungsstrebe auf als ein Restabschnitt der Begrenzungsstrebe, wobei der Restabschnitt der Begrenzungsstrebe vorzugsweise die gleiche Quererstreckung aufweist wie die weiteren Streben der Rahmenteile. Durch die erhöhte Quererstreckung wird ein gewünschter Höheneinstellbereich der Auflagefläche bzw. des vorderen Rahmenteils vorgegeben.According to a further development of the invention, the thickening has a larger transverse extension in the direction transverse to the elongated limiting strut than a remaining section of the limiting strut, the remaining section of the limiting strut preferably having the same transverse extension as the other struts of the frame parts. Due to the increased transverse extension a desired height adjustment range of the support surface or the front frame part is specified.

Nach einer Weiterbildung der Erfindung weist die Begrenzungsstrebe des vorderen Rahmenteils auf einer der Auflagefläche zugewandten Innenseite eine Schrägfläche auf, die sich in Richtung des oberen Endes der Begrenzungsstrebe verjüngt. Auf diese Weise besteht nur eine Verdickung in einem solchen Bereich, der die Öffnungsstellung des vorderen Rahmenteils bestimmt. Die Schließstellung des vorderen Rahmenteils wird nicht durch eine Verdickung gestört, da das obere Ende der Begrenzungsstrebe eine kleinere Quererstreckung aufweist als das untere Ende derselben.According to a further development of the invention, the limiting strut of the front frame part has an inclined surface on an inside facing the support surface, which tapers towards the upper end of the limiting strut. In this way, there is only a thickening in an area that determines the opening position of the front frame part. The closed position of the front frame part is not disturbed by a thickening, since the upper end of the limiting strut has a smaller transverse extension than the lower end of the same.

Nach einer Weiterbildung der Erfindung ist eine Klemmeinrichtung vorgesehen, mittels derer die Höhe der Auflagefläche stufenlos in einem Bereich zwischen dem als Anschlagfläche dienenden unteren Ende der oberen Verdickung und/oder dem als Anschlagfläche dienenden oberen Ende der unteren Verdickung der Begrenzungsstrebe festlegbar ist. Die Klemmeinrichtung kann lösbar mit dem Rahmenteil des Bettes verbunden sein.According to a further development of the invention, a clamping device is provided, by means of which the height of the support surface can be set continuously in an area between the lower end of the upper thickening serving as a stop surface and / or the upper end of the lower thickening of the limiting strut serving as a stop surface. The clamping device can be detachably connected to the frame part of the bed.

Nach einer Weiterbildung der Erfindung umfasst die Klemmeinrichtung ein erstes Klemmelement und ein mit demselben verbindbaren zweiten Klemmelement, wobei zumindest eines dieser Klemmelemente eine an den Durchmesser der Streben bzw. des Restabschnitts der Begrenzungsstrebe angepasste Ausnehmung aufweist. Vorteilhaft kann hierdurch eine stabile und einfache Verklemmung von vorzugsweise zwei benachbarten Streben erfolgen.According to a further development of the invention, the clamping device comprises a first clamping element and a second clamping element which can be connected to the same, at least one of these clamping elements having a recess adapted to the diameter of the struts or the remaining section of the limiting strut. This advantageously allows stable and simple clamping of preferably two adjacent struts.

Nach einer Weiterbildung der Erfindung ist das erste Klemmelement innenseitig des Rahmens angeordnet zur Bildung eines Auflagers für die Auflagefläche. Das zweite Klemmelement ist außenseitig des Rahmens angeordnet, wobei beide Klemmelemente Bohrungen aufweisen zum kraftschlüssigen Verspannen derselben. Als Befestigungsmittel ist vorzugsweise eine Schraube vorgesehen, die von außen des Bettes unter Eingreifen entsprechender Bohrungen des äußeren und inneren Klemmelementes in Schraubeingriff bringbar ist, so dass die beiden Klemmelemente miteinander verspannt werden. Die beiden Klemmelemente sind somit kraftschlüssig durch eine Schraubverbindung miteinander verbunden. Die Handhabung bei der Befestigung des Klemmelementes kann hierdurch vereinfacht werden.According to a further development of the invention, the first clamping element is arranged on the inside of the frame to form a support for the support surface. The second clamping element is arranged on the outside of the frame, with both clamping elements having holes for non-positive clamping the same. A screw is preferably provided as a fastening means, which can be brought into screw engagement from the outside of the bed by engaging corresponding bores in the outer and inner clamping elements, so that the two clamping elements are clamped together. The two clamping elements are thus non-positively connected to one another by a screw connection. The handling when attaching the clamping element can be simplified in this way.

Nach einer Weiterbildung der Erfindung ist das erste Klemmelement fest mit der Auflagefläche verbunden, so dass die Anzahl der losen Klemmelemente verringert werden kann.According to a further development of the invention, the first clamping element is firmly connected to the support surface, so that the number of loose clamping elements can be reduced.

Nach einer Weiterbildung der Erfindung weist die Verdickung der Begrenzungsstreben eine Länge in einem Bereich zwischen 25 % und 45 % der Länge der Begrenzungsstrebe auf, so dass hierdurch eine vorwählbare maximale Höhenverstellung gegeben ist.According to a further development of the invention, the thickening of the limiting struts has a length in a range between 25% and 45% of the length of the limiting strut, so that this provides a preselectable maximum height adjustment.

Zur Lösung der Aufgabe weist die Erfindung eine Klemmeinrichtung für das Bett auf, die als Zusatzteil für ein herkömmliches Bett, vorzugsweise mit Rahmenteilen auf vertikalen Streben, verwendbar ist.To solve the problem, the invention has a clamping device for the bed, which can be used as an additional part for a conventional bed, preferably with frame parts on vertical struts.

Ein höhenverstellbares Bett ist vorzugsweise als ein Kinderbett 1 ausgebildet, das vier aufrechte Rahmenteile 2, 3 aufweist, und zwar zwei gegenüberliegende stirnseitige Rahmenteile 2 und zwei gegenüberliegende längsseitige Rahmenteile 3. Die Rahmenteile 2, 3 weisen jeweils eine Anzahl von parallel zueinander und in einem Abstand a zueinander verlaufenden Streben 4 auf. Während die stirnseitigen Rahmenteile 2 neben die Streben 4 verbindenden Verbindungsstangen 5 auch aufrechte Standpfosten 6 aufweisen, die senkrecht zu denselben verlaufen, weisen die längsseitigen Rahmenteile lediglich Verbindungsstangen 7 auf, die die Streben 4 der längsseitigen Rahmenteile 3 begrenzen. Die Rahmenteile 2, 3 verlaufen in der Montagestellung in vertikaler Richtung. Die Rahmenteile 2, 3 bilden einen Rahmen und umgeben eine Auflagefläche 8 des Kinderbettes 1, die vorzugsweise als eine Brettfläche ausgebildet ist, auf der eine Matratze ablegbar ist.A height-adjustable bed is preferably designed as a child's bed 1, which has four upright frame parts 2, 3, namely two opposite front frame parts 2 and two opposite longitudinal frame parts 3. The frame parts 2, 3 each have a number of parallel to each other and at a distance a mutually extending struts 4. While the front frame parts 2, in addition to the connecting rods 5 connecting the struts 4, also have upright support posts 6 which run perpendicular to them, the longitudinal frame parts only have connecting rods 7 which delimit the struts 4 of the longitudinal frame parts 3. The frame parts 2, 3 run in the vertical direction in the assembly position. The frame parts 2, 3 form a frame and surround a support surface 8 of the child's bed 1, which is preferably designed as a board surface on which a mattress can be placed.

Nach einer nicht dargestellten alternativen Ausführungsform der Erfindung kann die Auflagefläche 8 auch als ein Lattenrost ausgebildet sein.According to an alternative embodiment of the invention, not shown, the support surface 8 can also be designed as a slatted frame.

Im vorliegenden Ausführungsbeispiel ist ein vorderes längsseitiges Rahmenteil 3' des Kinderbettes 1 verschwenkbar an den zugeordneten Standpfosten 6 gelagert, so dass es von einer in Figur 1 dargestellten Nutzungsstellung in eine in Figur 2 dargestellte Freigabestellung verbringbar ist, in der das Kind auf die Auflagefläche 8 auf- oder von derselben absetzbar ist.In the present exemplary embodiment, a front longitudinal frame part 3 'of the child's bed 1 is pivotally mounted on the associated support post 6, so that it is supported by an in Figure 1 shown usage position into one in Figure 2 The release position shown can be moved, in which the child can be placed on or off the support surface 8.

Zur Einstellung der Höhe h der Auflagefläche 8 ist eine Klemmeinrichtung 9 vorgesehen, die im Wesentlichen ein erstes Klemmelement 10 und ein zweites Klemmelement 11 aufweist, die mittels einer Verschraubung an zwei benachbarten Streben 4 der Rahmenteile 2, 3 verspannbar sind. Das erste Klemmelement 10 ist auf einer der Auflagefläche 8 zugewandten Seite des Rahmenteils 2, 3 angeordnet, während das zweite Klemmelement 11 auf einer der Auflagefläche 8 abgewandten Seite des Rahmenteils 2, 3 angeordnet ist. Das erste Klemmelement 10 ist somit innenseitig des durch die Rahmenteile 2, 3 gebildeten Rahmen des Kinderbettes 1 und das zweite Klemmelement 11 außenseitig desselben Rahmens angeordnet. Wie aus Figur 5 ersichtlich ist, verläuft das Rahmenteil 2, 3 in einer vertikalen Erstreckungsebene E.To adjust the height h of the support surface 8, a clamping device 9 is provided, which essentially has a first clamping element 10 and a second clamping element 11, which can be clamped to two adjacent struts 4 of the frame parts 2, 3 by means of a screw connection. The first clamping element 10 is arranged on a side of the frame part 2, 3 facing the support surface 8, while the second clamping element 11 is arranged on a side of the frame part 2, 3 facing away from the support surface 8. The first clamping element 10 is thus arranged on the inside of the frame of the child's bed 1 formed by the frame parts 2, 3 and the second clamping element 11 is arranged on the outside of the same frame. How out Figure 5 As can be seen, the frame part 2, 3 runs in a vertical extension plane E.

Das erste Klemmelement 10 und das zweite Klemmelement 11 sind jeweils leistenförmig ausgebildet und weisen eine Länge I auf, die größer ist als die Summe aus dem lichten Abstand a benachbarter Streben 4 und einem doppelten Durchmesser der Streben 4. In der Festlegposition bzw. Verriegelungsstellung der Klemmeinrichtung 9 umfassen die beiden Klemmelemente 10, 11 somit die zwei benachbarten Streben 4 von Rahmenteilen 2, 3.The first clamping element 10 and the second clamping element 11 are each strip-shaped and have a length I that is greater than the sum of the clear distance a between adjacent struts 4 and twice the diameter of the struts 4. In the fixing position or locking position of the clamping device 9, the two clamping elements 10, 11 thus include the two adjacent struts 4 of frame parts 2, 3.

Damit die benachbarten Streben 4 annähernd vollständig von den Klemmelementen 10, 11 in Umfangsrichtung umschlossen sind, weisen die Klemmelemente 10, 11 jeweils eine Nut 12, 13 auf, deren Kontur an die Form der Streben 4 angepasst sind. Die benachbarten Streben 4 werden somit unter Anlage der Nuten 12, 13 vollständig von den Klemmelementen 10, 11 umgeben.So that the adjacent struts 4 are almost completely enclosed by the clamping elements 10, 11 in the circumferential direction, the clamping elements point 10, 11 each have a groove 12, 13, the contour of which is adapted to the shape of the struts 4. The adjacent struts 4 are thus completely surrounded by the clamping elements 10, 11 with the grooves 12, 13 in contact.

Im vorliegenden Ausführungsbeispiel weisen die Klemmelemente 10, 11 jeweils die Nuten 12, 13 gleicher Kontur, nämlich im Querschnitt halbkreisförmiger Kontur, auf.In the present exemplary embodiment, the clamping elements 10, 11 each have the grooves 12, 13 of the same contour, namely a semicircular contour in cross section.

Nach einer nicht dargestellten alternativen Ausführungsform der Erfindung kann auch lediglich das erste Klemmelement 10 zwei Nuten aufweisen, während das zweite Klemmelement 11 keine Nut aufweist. Alternativ können die Nuten des ersten Klemmelementes 10 und des zweiten Klemmelementes 11 auch eine unterschiedliche Nuttiefe bzw. Kontur aufweisen.According to an alternative embodiment of the invention, not shown, only the first clamping element 10 can have two grooves, while the second clamping element 11 has no groove. Alternatively, the grooves of the first clamping element 10 and the second clamping element 11 can also have a different groove depth or contour.

Dadurch, dass das erste Klemmelement 10 auf der Innenseite des Rahmens angeordnet ist, bildet es ein Auflager bzw. Anschlag für die Auflagefläche 8. In Abhängigkeit von der Anordnung der Klemmeinrichtung 9 kann somit die Auflagefläche 8 stufenlos in der Höhe h eingestellt werden. Im vorliegenden Ausführungsbeispiel sind allen Rahmenteilen 2, 3 mit Ausnahme des vorderseitigen Rahmenteils 3' Klemmeinrichtungen 9 zugeordnet. Den stirnseitigen Rahmenteilen 2 sind jeweils eine einzige Klemmeinrichtung 9 und dem längsseitigen hinteren Rahmenteil 3 zwei Klemmeinrichtungen 9 zugeordnet, wie insbesondere aus Figur 1 ersichtlich ist.Because the first clamping element 10 is arranged on the inside of the frame, it forms a support or stop for the support surface 8. Depending on the arrangement of the clamping device 9, the height h of the support surface 8 can thus be adjusted continuously. In the present exemplary embodiment, all frame parts 2, 3 are assigned clamping devices 9 with the exception of the front frame part 3 '. The front frame parts 2 are each assigned a single clamping device 9 and the longitudinal rear frame part 3 is assigned two clamping devices 9, as shown in particular Figure 1 is visible.

Das erste Klemmelement 10 und das zweite Klemmelement 11 sind vorzugsweise gleich groß ausgebildet, wobei mittels der Nuten 12, 13 Anlagefläche an benachbarte Streben 4 vorgesehen sind. Das erste Klemmelement 10 und das zweite Klemmelement 11 bilden somit Klemmbacken, die durch Zusammenfügen in einer bestimmten Höhe die Höhe h der Auflagefläche 8 vorgeben.The first clamping element 10 and the second clamping element 11 are preferably of the same size, with contact surfaces on adjacent struts 4 being provided by means of the grooves 12, 13. The first clamping element 10 and the second clamping element 11 thus form clamping jaws which, when joined together at a certain height, specify the height h of the support surface 8.

Im vorliegenden Ausführungsbeispiel weisen das erste Klemmelement 10 und das zweite Klemmelement 11 jeweils eine Bohrung 14, 15 auf, die vorzugsweise zwischen den Nuten 12, 13 der jeweiligen Klemmelemente 10, 11 angeordnet sind. Die Bohrungen 14, 15 fluchten in der Montagestellung zueinander, so dass in der Montagestellung ein Ende des Schaftes 17 der Befestigungsschraube 16 durch die Bohrung 15 des zweiten Klemmelementes 11 durchsteckbar und in die Bohrung 14 des ersten Klemmelementes 10 einsteckbar ist. Die Bohrung 14 des ersten Klemmelementes 10 weist ein Innengewinde auf, mit dem die Befestigungsschraube 16 in Eingriff bringbar ist. Die Bohrung 15 des zweiten Klemmelementes 11 weist einen solchen Durchmesser auf, dass der Schaft 17 der Befestigungsschraube 16 mit Spiel einsetz- und durchsteckbar ist. Die Befestigungsschraube 16 weist einen Kopf 18 auf, der einen größeren Durchmesser aufweist als die Bohrung 15 des zweiten Klemmelementes 11. Auf diese Weise kann mittels eines beispielsweise Inbuswerkzeugs 19 die Befestigungsschraube 16 in Schraubeingriff mit dem ersten Klemmelement 10 verbracht werden, wobei das erste Klemmelement 10 und das zweite Klemmelement 11 unter Einschluss der benachbarten Streben 4 miteinander verspannt werden. Nach erfolgtem Verspannen aller vier Klemmeinrichtungen 9 in der gleichen Höhe h kann die Auflagefläche 8 unter Anlage derselben an den ersten Klemmelementen 10 eingesetzt werden.In the present exemplary embodiment, the first clamping element 10 and the second clamping element 11 each have a bore 14, 15, which are preferably arranged between the grooves 12, 13 of the respective clamping elements 10, 11. The bores 14, 15 are aligned with one another in the assembly position, so that in the assembly position one end of the shaft 17 of the fastening screw 16 can be pushed through the bore 15 of the second clamping element 11 and inserted into the bore 14 of the first clamping element 10. The bore 14 of the first clamping element 10 has an internal thread with which the fastening screw 16 can be brought into engagement. The bore 15 of the second clamping element 11 has such a diameter that the shaft 17 of the fastening screw 16 can be inserted and pushed through with play. The fastening screw 16 has a head 18 which has a larger diameter than the bore 15 of the second clamping element 11. In this way, by means of an Allen tool 19, for example, the fastening screw 16 can be brought into screw engagement with the first clamping element 10, the first clamping element 10 and the second clamping element 11 is clamped together, including the adjacent struts 4. After all four clamping devices 9 have been clamped at the same height h, the support surface 8 can be inserted into contact with the first clamping elements 10.

Nach einer alternativen Ausführungsform der Erfindung kann zumindest eine Strebe 4' der jeweiligen Rahmenteile 2, 3 eine Verdickung 20 aufweisen, die als Anschlag für die Klemmeinrichtung 9 dient. Wie aus Figur 4 ersichtlich ist, kann die Klemmenrichtung 9 mit dem ersten Klemmelement 10 und dem zweiten Klemmelement 11 beispielsweise an einem unteren Ende der Verdickung 22 angesetzt werden, wobei die Anschlagfläche der Verdickung 20 einer bestimmten Höhe der Auflagefläche 8 zugeordnet ist. Insbesondere kann hierdurch eine Maximalhöhe der Auflagefläche 8 vorgegeben werden. Unterhalb des Anschlags der Verdickung 20 kann die Höhe der Auflagefläche 8 stufenlos verstellt werden. Vorteilhaft kann somit die Auflagefläche 8 in vorgesehene Höhen eingestellt werden.According to an alternative embodiment of the invention, at least one strut 4 'of the respective frame parts 2, 3 can have a thickening 20, which serves as a stop for the clamping device 9. How out Figure 4 As can be seen, the clamping direction 9 with the first clamping element 10 and the second clamping element 11 can be placed, for example, at a lower end of the thickening 22, the stop surface of the thickening 20 being assigned to a certain height of the support surface 8. In particular, this allows a maximum height of the support surface 8 to be specified. Below the stop of the thickening 20, the height of the support surface 8 can be infinitely variable be adjusted. The support surface 8 can thus advantageously be adjusted to the intended heights.

Nach einer alternativen Ausführungsform der Erfindung können die Bohrungen 14, 15 der Klemmelemente 10, 11 jeweils als Durchgangsbohrung ohne Innengewinde vorgesehen sein. Zum Verspannen der Klemmelemente 10, 11 ist eine Flügelmutter vorgesehen, die an einem freien Ende der Befestigungsschraube 16 aufschraubbar ist.According to an alternative embodiment of the invention, the bores 14, 15 of the clamping elements 10, 11 can each be provided as a through bore without an internal thread. To clamp the clamping elements 10, 11, a wing nut is provided, which can be screwed onto a free end of the fastening screw 16.

Vorzugsweise bestehen die Rahmenteile 2, 3 bzw. Streben 4 aus einem Holzmaterial. Auch die Klemmelemente 10, 11 bestehen aus einem Holzmaterial.The frame parts 2, 3 and struts 4 preferably consist of a wooden material. The clamping elements 10, 11 also consist of a wooden material.

Die Klemmelemente 10, 11 dienen als Mittel zur Höhenverstellung. Das innenseitig angeordnete erste Klemmelement 10 dient als Tragemittel, auf dem die Auflagefläche 8 in der Montagestellung aufliegt. Zusätzlich bilden das erste Klemmelement 10 und das zweite Klemmelement 11 Anschlussmittel, die an dem jeweiligen Rahmenteil 2, 3 bzw. an zwei benachbarten Streben 4 derselben Rahmenteile 2, 3 befestigbar sind. In der Montageposition sind das erste Klemmelement 10 und das zweite Klemmelement 11 fest miteinander verbunden.The clamping elements 10, 11 serve as means for height adjustment. The first clamping element 10 arranged on the inside serves as a support means on which the support surface 8 rests in the assembly position. In addition, the first clamping element 10 and the second clamping element 11 form connection means which can be fastened to the respective frame part 2, 3 or to two adjacent struts 4 of the same frame parts 2, 3. In the assembly position, the first clamping element 10 and the second clamping element 11 are firmly connected to one another.

Nach einer alternativen Ausführungsform der Erfindung können die Klemmelemente 10, 11 auch eine größere Länge aufweisen, so dass beispielsweise drei oder mehr Streben 4 in einer horizontalen Ebene teilweise oder vollständig umschlossen werden. Hierdurch ist die Auflagefläche des ersten Klemmelementes 10 vergrößert, so dass beispielsweise die Anzahl der Klemmeinrichtungen 9 an einem längsseitigen Rahmenteil 3 verringert werden kann.According to an alternative embodiment of the invention, the clamping elements 10, 11 can also have a greater length, so that, for example, three or more struts 4 are partially or completely enclosed in a horizontal plane. As a result, the contact surface of the first clamping element 10 is enlarged, so that, for example, the number of clamping devices 9 on a longitudinal frame part 3 can be reduced.

Nach einer weiteren in den Figuren 6 bis 15 dargestellten Ausführungsform des Kinderbettes 1' befindet sich an den gegenüberliegenden stirnseitigen Rahmenteilen 2 eine Begrenzungsstrebe 4", die zum einen die obere Verdickung 20 und zum anderen eine untere Verdickung 21 aufweist.After another one in the Figures 6 to 15 In the illustrated embodiment of the child's bed 1', there is a limiting strut 4" on the opposite front frame parts 2, which has, on the one hand, the upper thickening 20 and, on the other hand, a lower thickening 21.

Gleiche Bauteile bzw. Bauteilfunktionen der Ausführungsbeispiele sind mit den gleichen Bezugsziffern versehen.The same components or component functions of the exemplary embodiments are provided with the same reference numbers.

Ein oberes Ende der Begrenzungsstrebe 4" ist mit der oberen Verbindungsstange 7 und ein unteres Ende der Begrenzungsstrebe 4" mit der unteren Verbindungsstange 7 verbunden, vorzugsweise in der gleichen Weise wie die anderen Streben 4 mit den jeweiligen Verbindungsstangen 7.An upper end of the limiting strut 4" is connected to the upper connecting rod 7 and a lower end of the limiting strut 4" is connected to the lower connecting rod 7, preferably in the same way as the other struts 4 are connected to the respective connecting rods 7.

Wie besser aus Figur 12 ersichtlich ist, weist die obere Verdickung 20 an einem unteren Ende 22 derselben eine Anschlagfläche 23 auf, an die das zweite Klemmelement 11 anschlägt, wenn sich die Auflagefläche 8 in der maximal einstellbaren Höhe befindet. Die untere Verdickung 21 derselben Begrenzungsstrebe 4" weist an einem oberen Ende 24 eine Anschlagfläche 25 auf, an die das zweite Klemmelement 11 in der untersten Stellung der Auflagefläche 8 zur Anlage kommt. Zwischen der oberen Verdickung 20 und der unteren Verdickung 21 erstreckt sich ein Restabschnitt 26 der Begrenzungsstrebe 4", der die gleiche Formgebung aufweist wie die weiteren Streben 4 des Bettes 1'. Die obere Verdickung 20 dient zur Höhenbegrenzung der Auflagefläche 8. Die untere Verdickung 21 dient zur Tiefenbegrenzung der Auflagefläche 8. Im vorliegenden Ausführungsbeispiel weist die obere Verdickung 20 eine Länge IO und die untere Verdickung 21 eine Länge IU auf, die in einem Bereich von 25 % bis 45 % einer Länge I1 der Begrenzungsstrebe 4" entspricht. Im vorliegenden Ausführungsbeispiel entspricht die Länge IO der oberen Verdickung 20 180 mm, die Länge IU der unteren Verdickung 21 245 mm und eine Länge IR des Restabschnitts 26 150 mm. Der Querschnitt des Restabschnitts 26 ist - wie bei den Streben 4 - kreisförmig, beispielsweise mit einem Durchmesser d1 von 16 mm, ausgebildet. Die obere Verdickung 20 und die untere Verdickung 21 sind im Querschnitt vieleckförmig, beispielsweise rechteckförmig, im vorliegenden Ausführungsbeispiel quadratisch ausgebildet. Die Quererstreckung d2 der oberen Verdickung 20 und unteren Verdickung 21 beträgt im vorliegenden Fall 24 mm.How better looking Figure 12 As can be seen, the upper thickening 20 has a stop surface 23 at a lower end 22 thereof, against which the second clamping element 11 abuts when the support surface 8 is at the maximum adjustable height. The lower thickening 21 of the same limiting strut 4" has a stop surface 25 at an upper end 24, against which the second clamping element 11 comes into contact in the lowest position of the support surface 8. A remaining section extends between the upper thickening 20 and the lower thickening 21 26 the limiting strut 4", which has the same shape as the other struts 4 of the bed 1'. The upper thickening 20 serves to limit the height of the support surface 8. The lower thickening 21 serves to limit the depth of the support surface 8. In the present exemplary embodiment, the upper thickening 20 has a length I O and the lower thickening 21 has a length I U , which is in a range of 25% to 45% corresponds to a length I 1 of the limiting strut 4". In the present exemplary embodiment, the length I O of the upper thickening corresponds to 20,180 mm, the length I U of the lower thickening corresponds to 21,245 mm and a length I R of the remaining section corresponds to 26,150 mm The cross section of the remaining section 26 is - as with the struts 4 - circular, for example with a diameter d1 of 16 mm. The upper thickening 20 and the lower thickening 21 are polygonal in cross section, for example rectangular, square in the present exemplary embodiment. The transverse extent d2 of the upper thickening 20 and lower thickening 21 is 24 mm in the present case.

Wie aus Figur 11 zu ersehen ist, sind die ersten Klemmelemente 10 durch Verschraubung 27 mit der Auflagefläche 8 verbunden. Das erste Klemmelement 10 und das zweite Klemmelement 11 weisen jeweils die halbkreisförmigen Nuten 12 bzw. 13 auf mit einem solchen Radius (im vorliegenden Ausführungsbeispiel 8 mm), dass beim Verspannen des ersten Klemmelementes 10 mit dem zweiten Klemmelement 11 die benachbarten Streben 4 bzw. im vorliegenden Ausführungsbeispiel der Restabschnitt 26 der Begrenzungsstrebe 4" mit der benachbarten Strebe 4 unter Formschluss miteinander verspannt sind. Es handelt sich bei dem ersten Klemmelement 10 und dem zweiten Klemmelement 11 um die gleichen Klemmelemente wie bei der ersten beschriebenen Ausführungsform. Der Unterschied besteht lediglich darin, dass das erste Klemmelement 10 mittels der Verschraubung 27 fest an der Auflagefläche 8 angebracht ist. Die Verspannkraft zwischen den beiden Klemmelementen 10, 11 erfolgt in Querrichtung der Streben 4 bzw. der Begrenzungsstrebe 4". Die Klemmelemente 10, 11 weisen jeweils zwei Nuten 12 bzw. 13 auf.How out Figure 11 As can be seen, the first clamping elements 10 are connected to the support surface 8 by a screw connection 27. The first clamping element 10 and the second clamping element 11 each have the semicircular grooves 12 and 13 with such a radius (8 mm in the present exemplary embodiment) that when the first clamping element 10 is clamped with the second clamping element 11, the adjacent struts 4 and 1, respectively In the present exemplary embodiment, the remaining section 26 of the limiting strut 4" is clamped together with the adjacent strut 4 in a form-fitting manner. The first clamping element 10 and the second clamping element 11 are the same clamping elements as in the first described embodiment. The only difference is that that the first clamping element 10 is firmly attached to the support surface 8 by means of the screw connection 27. The bracing force between the two clamping elements 10, 11 takes place in the transverse direction of the struts 4 or the limiting strut 4". The clamping elements 10, 11 each have two grooves 12 and 13, respectively.

Wie aus Figur 11 zu ersehen ist, erfolgt die Höheneinstellung der Auflagefläche 8 mittels an drei Seiten des Rahmens angeordneter Klemmeinrichtung 9. Die Klemmeinrichtung 9 ist an gegenüberliegenden stirnseitigen Rahmenteilen 2 und an dem rückseitigen Rahmenteil 3 angeordnet. Das vorderseitige Rahmenteil 3 weist keine Klemmeinrichtung auf. Es besteht aus einem in vertikaler Richtung verschiebbaren bewegbaren Rahmenteil 3`.How out Figure 11 As can be seen, the height of the support surface 8 is adjusted by means of a clamping device 9 arranged on three sides of the frame. The clamping device 9 is arranged on opposite front frame parts 2 and on the rear frame part 3. The front frame part 3 has no clamping device. It consists of a movable frame part 3` that can be moved in the vertical direction.

Das vordere Rahmenteil 3` weist an gegenüberliegenden Endbereichen 28 jeweils eine Begrenzungsstrebe 4‴ auf, die in einem oberen Bereich eine Verdickung 29 aufweisen. Die Verdickung 29 weist auf einer der Auflagefläche 8 zugewandten Innenseite eine Schrägfläche 30 auf, die sich in Richtung des oberen Endes der Begrenzungsstrebe 4‴ verjüngt. An einem unteren Ende der Verdickung 29 ist eine Anschlagfläche 31 vorgesehen, die eine solche Quererstreckung aufweist, dass beim geführten Herunterbewegen des vorderen Rahmenteils 3' von einer in Figur 6 dargestellten Schließstellung in eine in Figur 8 dargestellte Öffnungsstellung die Anschlagfläche 31 auf die Auflagefläche 8 zur Anlage kommt. Das vordere Rahmenteil 3' ist somit in der Öffnungsstellung durch die Verdickung 29 begrenzt. Die Verdickung 29 ermöglicht somit eine Tiefenbegrenzung des vorderen Rahmenteils 3', was einen Ausfallschutz für das in dem Bett 1' befindliche Kind bietet. Das vordere Rahmenteil 3' ist in üblicher Weise längsverschieblich in der Höhe geführt gelagert. Die Verdickung 29 kann im Bereich der Anschlagfläche 31 ebenfalls vieleckförmig oder rechteckförmig oder quadratisch ausgebildet sein.The front frame part 3 'has a limiting strut 4' at opposite end regions 28, which have a thickening 29 in an upper region. The thickening 29 has an inclined surface 30 on an inside facing the support surface 8, which tapers towards the upper end of the limiting strut 4‴. At a lower end of the thickening 29, a stop surface 31 is provided, which has such a transverse extension that when the front frame part 3 'is moved downwards from an in Figure 6 shown closed position into an in Figure 8 Open position shown, the stop surface 31 comes into contact with the support surface 8. The front frame part 3 'is thus limited in the open position by the thickening 29. The thickening 29 thus enables the depth of the front frame part 3 'to be limited, which offers fall protection for the child in the bed 1'. The front frame part 3 'is mounted in the usual way so that it can be moved longitudinally in height. The thickening 29 can also be polygonal or rectangular or square in the area of the stop surface 31.

Wie aus Figur 10 ersichtlich ist, ist die Quererstreckung der Anschlagfläche 31 so groß, dass beim Herunterlassen des vorderen Rahmenteils 3` die Anschlagfläche 31 an der Auflagefläche 8 anschlägt. Die Auflagefläche 8 stellt somit einen Bezugspunkt für die Öffnungsstellung des vorderen Rahmenteils 3' her. Vorteilhaft ist hierdurch die Öffnungshöhe durch eine Länge IO' der Verdickung 29 festgelegt. Unabhängig von der mittels der Klemmeinrichtung 9 eingestellten Höhe der Auflagefläche 8 wird beim Verbringen des vorderen Rahmenteils 3' in die Öffnungsstellung stets die gleiche Öffnungshöhe hO eingestellt. Die Öffnungshöhe hO ist definiert durch den vertikalen Abstand des vorderen Rahmenteils 3' in der Schließstellung und in der Öffnungsstellung. Die Länge IO' der Verdickung 29 entspricht somit der Öffnungshöhe hO. Nach einer alternativen Ausführungsform der Erfindung kann die Klemmeinrichtung 9 auch derart ausgebildet sein, dass sie mit lediglich einer einzigen Strebe 4 oder mit mehr als zwei Streben 4 verbunden ist, wobei innenseitig, also innerhalb des Rahmens des Bettes, ein Vorsprung gebildet wird, auf der die Auflagefläche 8 aufliegt, dies vorzugsweise an mindestens drei Rahmenseiten. Im vorliegenden Ausführungsbeispiel sind die ersten Klemmelemente 10 an der Auflagefläche 8 befestigt, so dass die Höhe der jeweiligen Klemmeinrichtungen 9 an den unterschiedlichen Rahmenseiten vorgegeben ist. Die Bedienperson muss lediglich das zweite Klemmelement an den drei Rahmenseiten mit dem ersten Klemmelement 10 verspannen, so dass eine feste Verbindung zwischen den Streben 4 und der die Matratze aufnehmenden Auflagefläche 8 gegeben ist.How out Figure 10 As can be seen, the transverse extent of the stop surface 31 is so large that when the front frame part 3' is lowered, the stop surface 31 hits the support surface 8. The support surface 8 thus creates a reference point for the open position of the front frame part 3 '. As a result, the opening height is advantageously determined by a length I O 'of the thickening 29. Regardless of the height of the support surface 8 set by means of the clamping device 9, the same opening height h O is always set when the front frame part 3 'is moved into the open position. The opening height h O is defined by the vertical distance of the front frame part 3 'in the closed position and in the open position. The length I O 'of the thickening 29 therefore corresponds to the opening height h O. According to an alternative embodiment of the invention, the clamping device 9 can also be designed in such a way that it is connected to only a single strut 4 or to more than two struts 4, with a projection being formed on the inside, i.e. within the frame of the bed the support surface 8 rests, preferably on at least three frame sides. In the present exemplary embodiment, the first clamping elements 10 are fastened to the support surface 8, so that the height of the respective clamping devices 9 is predetermined on the different frame sides. The operator only has to clamp the second clamping element on the three frame sides with the first clamping element 10, so that there is a firm connection between the struts 4 and the support surface 8 that accommodates the mattress.

Das erfindungsgemäße Bett kann insbesondere für Beistell- und/oder Anstellbetten oder Stubenwagen eingesetzt werden, wobei vorzugsweise eine Seite des Bettes mittels des vorderen Rahmenteils, das vorzugsweise als Schiebegitter ausgebildet ist, zumindest teilweise geöffnet werden kann.The bed according to the invention can be used in particular for side and/or additional beds or bassinets, wherein preferably one side of the bed can be at least partially opened by means of the front frame part, which is preferably designed as a sliding grille.
