Abstract

The length of the segments can be varied according to the angles of the segments. The length is altered after removing a lock by using the user's muscular force against spring force. The length of at least one segment - for the pelvis, thighs, bottom - can be varied by replacing, lengthening the segment but by not dismantling the slatted mattress grid. At least one segment has lateral struts (A,B) each of which is divided into two parts (A',A'').

Description

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1 sowie eine Vorrichtung zu dessen Durchführung. Vorrichtungen zum Auflegen von Matratzen, die heute überwiegend federnde Latten als Träger- und Federungselemente aufweisen und in diesem Fall als Lattenroste bezeichnet werden, werden meist als ein einziges Segment oder auch als zwei Segmente gefertigt, im letzteren Fall ist ein kleines Segment zum Tragen von Kopf und Hals ausgelegt und gegenüber dem größeren Teil abwinkelbar. Bei diesen beiden Ausführungsformen kann der gleiche Rost problemlos für eine Vielzahl von Körpergrößen eingesetzt werden.The invention relates to a method according to the preamble of claim 1 and a Device for carrying it out. Devices for laying mattresses that are today predominantly have resilient slats as support and suspension elements and in this case as Slatted frames are usually referred to as a single segment or as two segments manufactured, in the latter case a small segment is designed for carrying the head and neck bendable towards the larger part. In these two embodiments the same can be done Rust can be easily used for a variety of body sizes.

In neuerer Zeit werden zusätzlich Roste angeboten, die in eine größere Anzahl von Segmenten aufgeteilt sind. Beispielsweise ist jeweils ein Segment zum Tragen von Kopf, Rumpf, Becken, Oberschenkel und Unterschenkel mit Fuß vorgesehen. Die Verstellung der Winkel der Segmente gegeneinander wird meist durch einen Elektromotor vorgenommen; in diesem Fall wird der Rost als Motorrahmen bezeichnet. Bei diesen segmentierten Rosten tritt das von Stühlen her bekannt Problem aufs daß die Segmente des Möbels den jeweiligen Körpersegmenten angepaßt werden muß, wie bei den Bürostühlen die Sitzhöhe der Länge von Unterschenkel mit Fuß und Schuh angepaßt wird.In recent times, additional grates are offered, which are in a larger number of segments are divided. For example, a segment for carrying the head, trunk, pelvis, Thigh and lower leg provided with foot. Adjusting the angle of the segments against each other is usually done by an electric motor; in this case the grate is called Designated engine frame. The problem known from chairs arises with these segmented gratings so that the segments of the furniture must be adapted to the respective body segments, as with the office chairs the seat height is adjusted to the length of the lower leg with foot and shoe.

Bei Rosten stellt sieh insbesondere das Problem, daß die Länge des Beckensegments für eine individuelle Abstimmung der Stärke von Bauch und Oberschenkeln angepaßt werden sollte und daß die Lange des Oberschenkelsegments der Länge des Oberschenkels angepaßt werden sollte. Weiterhin sollte die Segmentlänge auch mit den Segmentwinkeln variieren, da beispielsweise der Leib des Benutzers bei Anwinkeln von Rumpfsegment und Oberschenkelsegment gegenüber dem Beckensegment eingezwängt wird.The problem with rusting is that the length of the pelvic segment for one individual adjustment of the strength of the abdomen and thighs should be adjusted and that the length of the thigh segment should be adjusted to the length of the thigh. Furthermore, the segment length should also vary with the segment angles, since for example the Body of the user when the torso segment and thigh segment are angled towards the Pelvic segment is squeezed.

Aufgabe der Erfindung ist die Schaffung eines Verfahrens zum Anpassen eines gattungsgemäßen Rostes an variierende Anforderungen und Gegebenheiten sowie eine Vorrichtung zur Durchführung des Verfahrens. Ziel der Anpassung sind insbesondere ein hoher Liegekomfort und/oder das Erreichen vorgegebener gesundheitlicher Ziele. Die Aufgabe wird dadurch gelöst, daß die Länge der jeweiligen Segmente in Abhängigkeit von den jeweiligen Bedingungen variiert wird und durch eine Sitz- oder Liege-Vorrichtung zur Durchführung des Verfahrens, die dadurch gekennzeichnet ist, daß die Länge mindestens eines der Segmente in der Längsrichtung in der Vorrichtung variierbar ist. Diese Anpassung ist im Detail recht komplex und kann auf vielfältige Weise gemäß Kennzeichnung in den Unteransprüchen erreicht werden. Diese berücksichtigen die folgenden Aspekte:The object of the invention is to provide a method for adapting a generic Rust to varying requirements and conditions as well as a device for implementation of the procedure. The aim of the adaptation is in particular a high level of comfort and / or that Achieve predetermined health goals. The object is achieved in that the length of the respective segments depending on the respective conditions is varied and by a Sitting or lying device for performing the method, which is characterized in that the length of at least one of the segments can be varied in the longitudinal direction in the device. This adjustment is quite complex in detail and can be done in a variety of ways according to labeling can be achieved in the subclaims. These take into account the following aspects:

- Those segments are named for which length adjustment is particularly important.
- Lateral frame elements of the segment, hereinafter referred to as spars, are depending on Request extended or shortened.
- An easy to implement extension method is to cut open the bars and move the parts apart. In this case the problem is solved that the slats too move apart and that there is a space in which the mattress cannot lie.
- Solutions must be specified for a suitable drive that extends the segments or shortened
- The setting can also be made when the user is lying on the grate; this is particular important under the aspects of speed, convenience and - if the attitude after subjective criteria - reliability, the desired and technically possible To achieve lying quality.
- If the setting is made according to objective criteria, these must be named and the possibility of Creating realization.
- The advanced process is simple, cheap, manageable and safe.

Die durch die Unteransprüche erbrachten Merkmale und Vorteile lassen sich wie folgt zusammenfassen:The features and advantages provided by the subclaims can be as follows sum up:

1. Naming those segments in which length adjustment is particularly important
2. Creation of a smooth and stable extension of the bars of a segment,
3. Cover the resulting gap between the slats in such a way that the smoothness remains preserved, and
4. Setting the segment length according to the user's subjective criteria in such a way that the User - analogous to the adjustment of the segment angle - lies on the mattress and grate and the Segment lengths adjusted to satisfaction

Bevorzugte Merkmale sind im folgenden dargelegt.Preferred features are set out below.

1. The segments for which a length setting is particularly important are based on Statements from users and based on physiological considerations. In relation on the pelvic segment, in addition to complaining about squeezing when bending the trunk and Note the thigh segment that if the pelvic segment is too large, the pelvis forward slips and tilts with respect to the spine, resulting in increased pressure and Tensile stresses on the intervertebral discs of the lumbar spine leads. A length adjustment of the Thigh segment is important because the thigh length is the same to those Body measurements that vary the most. A segment length that is too long leads to a segment length that is too long Pressure in the back of the knee, a length that is too small leads to high heel pressure. Furthermore is a Setting the length of the fuselage segment is important. Is the top of this segment not on the shoulder blades, the head becomes without using a pillow overstretched or unsupported.
2. Each spar of a segment to be extended is cut into preferably two part spars divided, then both partial spars are reconnected by a device, the one Longitudinal displacement of the spars, d. H. in the longitudinal direction of the grate and thus a Enlargement and subsequent shrinking of the segment in the longitudinal direction of the body allowed. This device can be formed by two coaxial tubes. But there is less friction Arrangement in which the device of a partial spar by rollers or balls opposite the Device of the other horn is guided, as is known from the guidance of sliding doors is. It is particularly advantageous to use a gas spring that not only performs the task of guiding, but also that of force generation and blocking can take over.
3. From DE-GM 90 12 719.6 an arrangement is known with which gaps between slats can be closed. Here, slats are connected to spars using adhesive fasteners, so that the slats can be easily removed and modified to match the spar dimensions. However, the setting cannot be made here when the user is lying on the grate. In particular, the arrangement according to the invention is developed by the following features:
On at least one slat, which is fastened to one of the partial spars, one or more plates are fastened, which rest on the or the next slat of the other partial spar, without being fastened there. As a result, the gap is closed even with varying distances between the partial spars. The spring behavior of the segment is improved if the plate is designed to be resilient in the longitudinal and / or transverse direction.
Instead of using slabs, the gap can also be covered with slats that protrude beyond the intersection of the partial spars. This can be achieved by attaching inwardly open rails to the partial spars, which protrude beyond the intersection of the partial spars, one rail encompassing the other. The slats run in the rails, with all slats in a segment being connected to one another by resilient elements such as elastic bands. If the distance between the partial spars is increased, then distribute the slats evenly in the rails and prevent the formation of a gap between the slats. Alternatively, the rails of the two partial spars can be arranged one above the other and thus pass over one another when the distance between the partial spars is reduced. In this case the slats are fixed in the rails; This avoids costly technical solutions, whereby a step in the grate must be accepted for guiding the slats in the rails without tilting.
Another alternative arrangement for closing the gap is to span the gap with a stretchable material, e.g. B. with an elastic textile belt. The problem that the stretchable material has to stretch very much, which most materials are not designed for, is addressed as follows. The belt is stretched diagonally across the gap, e.g. B. from the left foot-side to the right head-side part spar, so that the belt already has a large initial length and the additional length of 10 cm required by increasing the distance between the part spars only leads to a relative elongation of the order of 10%. Another advantage of the diagonal tension is that the belt can be attached to the strong bars and not to the weak slats.
Another approach is to stretch continuously stretchable material between the skirting board and the top bar of the grate, which is deflected at the respective ends of the segments in the direction of the adjacent segment and thus always runs in the plane of the segments. It is advantageous to design the deflection elements as resilient rods in order to maintain the spring character of the grate at the segment boundaries as well as to provide slats as additional spring elements in the fields of the segments. The main advantage of this arrangement is that the elongation of a segment affects all of the material and so results in little stretch. Extending a segment by 10 cm only creates an approximately 5% relative elongation of the material.
4. The final step relates to the setting of the segment length on the body data of the user and the segment angle. In the technically simplest case, this is done analogously to Adjusting the headboard angle of a simple two-part grate: The user stands next to the Bed and adjusts the angle according to an estimate, lies down on the bed, tests the setting and then correct them several times if necessary. However, it is experience that the user corrects frequently omits because of the cumbersome procedure and with only a rough adjustment to his Satisfies needs. With modern motor beds, on the other hand, he can adjust when lying down make very sensitive and easy.

Analog ist es Zielstellung des Verfahrens der Längenverstellung der Segmente, die Verstellung im Liegen nach subjektiver sensorischer Kontrolle des Benutzers vorzunehmen. Dies wird der Alternative vorgezogen, den Rost zunächst auf die Körperdaten einzustellen und die sich aus der Winkeländerung ergebende Korrektur durch eine Kopplung von Winkeländerung und Längen änderung vorzunehmen. Zum einen ist diese Kopplung technisch schwierig zu bewerkstelligen, wenn sie auch durch ein mechanisches Getriebe oder durch eine Umrechnung in einem Mikroprozessor denkbar ist. Zum anderen schränkt sie die Handlungsfreiheit des Benutzers ein, ein Abweichen von der Norm aufgrund eines geänderten Bedürfnisses ist schwierig.Similarly, the aim of the method of length adjustment of the segments, the adjustment in the Lying to be done after subjective sensory control of the user. This will be the Alternatively preferred to first adjust the grate to the body data and which results from the Correction resulting in change in angle by coupling angle change and lengths make change. For one thing, this coupling is technically difficult to achieve, if it also through a mechanical gear or through a conversion in a microprocessor is conceivable. Secondly, it restricts the user's freedom of action, a deviation from the norm due to a changed need is difficult.

Zur Realisierung der Längeneinstellung im Liegen nach subjektiver Kontrolle wurde zunächst eine motorgetriebene Verstellung in Betracht gezogen. Dies verursacht aber zum einen zusätzliche Kosten und zum anderen zusätzliche Arbeitsgänge bei der Einstellung. Zur Winkeleinstellung des Rücken-, Oberschenkel- und ggf. Unterschenkel-Segments kommen typischerweise die Längeneinstellungen des Becken- und Oberschenkel-Segments hinzu; dadurch wächst die Wahrscheinlichkeit, daß manche Benutzer überfordert werden oder aus anderen Gründen die Möglichkeiten des Rostes nicht voll nutzen.To realize the length adjustment while lying down after subjective control, one was first motorized adjustment considered. On the one hand, however, this causes additional costs and, on the other hand, additional work steps when hiring. For angle adjustment of the back, Thigh and possibly lower leg segment typically come the length settings of the Pelvic and thigh segments added; this increases the likelihood that some Users are overwhelmed or for other reasons the possibilities of the grate are not fully use.

Daher wird eine Anordnung vorgesehen, die folgendes Verfahren ermöglicht. Die Segmente sind in der Länge verstellbar, normalerweise ist aber die Verstellmöglichkeit blockiert und das Segment in der Lange fixiert. Beim Anpassen auf die Daten eines neuen Benutzers, bei Änderung der Anpassung oder bei Änderung der Segmentlänge aufgrund einer Winkeländerung wird die Blockierung aufgehoben und das Segment wird durch Zunahme des Drucks durch den Benutzer vergrößert oder wird bei Abnahme des Drucks durch Federwirkung verkleinern. Es läuft also ein Regelvorgang ab, als dessen Stellgröße der Hautdruck wirkt.An arrangement is therefore provided which enables the following method. The segments are in the length is adjustable, but the adjustment is usually blocked and the segment in Tall Hendrik fixed. When adapting to the data of a new user, when changing the adaptation or when the segment length changes due to a change in angle, the blocking becomes canceled and the segment is enlarged or increased by increasing user pressure will decrease when the pressure decreases due to spring action. So there is a control process the skin pressure acts as its manipulated variable.

Dieser Regelvorgang kann prinzipiell durch technische Drucksensoren realisiert werden, die nach einen Soll/Istwert-Vergleich Elektromotoren zur Längenänderung ansteuern. Einfacher ist es aber, den Druck durch den Körper direkt auszunutzen, um die Segmentlänge wunschgemäß einzustellen. Insbesondere ist es dabei möglich, durch Körperbewegungen (wie dem Vorschieben des Beckens oder durch Herunterdrücken des Unterschenkels) den Anlagedruck einfach, direkt und ohne Erlernen einer besonderen Handhabung zu beeinflussen.In principle, this control process can be implemented by technical pressure sensors that follow Control a setpoint / actual value comparison of electric motors to change the length. But it is easier take advantage of the body's pressure directly to adjust the segment length as required. In particular, it is possible through body movements (such as pushing the pelvis forward or by pressing the lower leg) the system pressure simply, directly and without learning to influence a special handling.

Voraussetzung dieses vorteilhaften Verfahrens ist eine Leichtgängigkeit der Längenverstellung der Segmente, so daß zur Verstellung in die eine Richtung nur geringe Federkräfte und zur Verstellung in die andere Richtung nur geringe Muskelkräfte notwendig sind. Dies wird durch die Anordnungen zu den Schritten 1. und 2. geleistet, insbesondere durchA prerequisite for this advantageous method is that the length adjustment of the Segments, so that only slight spring forces for adjustment in one direction and for adjustment in the other direction only minimal muscle strength is necessary. This is due to the arrangements to steps 1 and 2, in particular by

- the ball bearing of the connecting elements between the partial spars,
- The smooth, continuous textile covering between the head and foot strips, the little friction generated for the mattress on top
- The low-friction deflection of the textile covering at the segment boundaries
- the insertion of a friction-reducing layer between the grate and mattress.

Fig. 1 zeigt das Segment eines Lattenrostes mit Holmen A und B und Latten C. Die Holme sind durch Schnitte D und D′ aufgetrennt, so daß Holm A in die Teilholme A′ und A′′ zerfällt. Beide Teilholme sind durch eine Vorrichtung E zum Verschieben in Längsachsen-Richtung der Holme verbunden, die durch kugelgelagerte Schienen ähnlich einer Schieberür-Aufhängung realisiert sein kann. Daneben sind die beiden Teilholme durch je eine Feder F, z. B. eine Spiralfeder oder eine Gasfeder verbunden, welche die Teilholme und damit die Teilsegmente G und G′ auseinanderschieben, wenn eine Blockierung gemäß weiter oben erfolgter Erläuterung aufgehoben wird. Die auseinandergeschobenen Teilsegmente sind in Fig. 2 dargestellt. Fig. 1 shows the segment of a slatted frame with spars A and B and slats C. The spars are separated by cuts D and D ', so that spar A breaks down into the partial spars A' and A ''. Both partial spars are connected by a device E for moving in the longitudinal axis direction of the spars, which can be realized by ball-bearing rails similar to a sliding door suspension. In addition, the two partial spars are each by a spring F, z. B. connected a coil spring or a gas spring, which push the partial spars and thus the sub-segments G and G 'apart when a blockage is released according to the explanation given above. The part segments pushed apart are shown in FIG. 2.

Die Fig. 3 bis 6 zeigen Ausführungsformen zum Abdecken der Lücken in der Lattenfläche. In Fig. 3 sind zwei Platten H und H′ auf einer Latte C des rechten Teilsegments befestigt und liegen auf einer Latte C′ des linken Teilsegments auf, so daß sie auf dieser Latte gleiten können, wenn das Segment vergrößert oder verkleinert wird. Eine gesonderte Vorrichtung E zum Verschieben wie eine Schiebetür-Aufhängung ist in Fig. 3 nicht vorgesehen, zwei biegestabile Gasfedern F und F′ übernehmen gleichzeitig die Aufgaben des Führens und des Auseinanderdrückens der Teilsegmente. In Fig. 4 sind elastische Gurte I und I′ diagonal über die Lücke in der Lattenfläche gespannt, diese übernehmen wie bereits dargelegt neben dem Stützen der Matratze gleichzeitig die Aufgabe, das Segment zu verkleinern. In Fig. 5 sind in einer Schnittzeichnung Schienen K und K′ gezeigt, die an den Teilholmen A′ und A′′ befestigt sind. Dabei hat Schiene K einen größere lichte Höhe als K′, so daß K die Schiene K′ umfaßt und beim Verkleinern des Segments K′ in K hineingleitet. In den Schienen liegen Latten C, die durch eine elastische Schnur L miteinander und mit den Endlatten M verbunden sind, so daß sieh die Latten bei Änderung der Segmentgröße gleichmäßig mit dem bereits dargelegten Vorteil in den Schienen verteilen. In Fig. 6 ragen die Schienen K und K′ ebenfalls über die Holme hinaus. Schiene K ist aber nahe der Oberkante von Teilholm A′ befestigt und Schiene K′ nahe der Unterkante von Teilholm A′′, so daß die Schienen bei Verkleinerung des Segments übereinander vorbeigeführt werden; die Latten C sind hier in den Schienen fixiert. FIGS. 3 to 6 show embodiments for covering the gaps in the bar surface. In Fig. 3, two plates H and H 'are attached to a crossbar C of the right sub-segment and lie on a crossbar C' of the left sub-segment so that they can slide on this crossbar when the segment is enlarged or reduced. A separate device E for moving like a sliding door suspension is not provided in Fig. 3, two flexurally stable gas springs F and F 'take over the tasks of guiding and pushing apart the sub-segments. In Fig. 4, elastic straps I and I 'are stretched diagonally across the gap in the slatted surface, these take over, as already explained, in addition to supporting the mattress at the same time the task of reducing the segment. In Fig. 5 rails K and K 'are shown in a sectional drawing, which are attached to the partial bars A' and A ''. Here, rail K has a greater clear height than K ', so that K comprises the rail K' and slides into K when the segment K 'is reduced. In the rails there are slats C, which are connected to each other and to the end slats M by an elastic cord L, so that when the segment size is changed, the slats are distributed evenly in the rails with the advantage already described. In Fig. 6, the rails K and K 'also protrude beyond the spars. Rail K is fastened near the upper edge of partial spar A 'and rail K' near the lower edge of partial spar A '', so that the rails are passed over one another when the segment is reduced; the slats C are fixed here in the rails.

Fig. 7 zeigt einen vollständigen Lattenrost mit den Segmenten N für Unterschenkel und Fuß, Oberschenkel O, Becken P, Rumpf Q und Kopf R. Das Oberschenkel-Segment N ist in der Länge variabel eingezeichnet, es wird durch eine Feder vergrößert und vom Benutzer durch Herabdrücken des Unterschenkels verkleinert; hier kann die Ausführungsform der Fig. 3 mit der Gasfeder E eingesetzt werden. Das Becken-Segment ist ebenfalls als variabel eingezeichnet, es wird durch eine Feder verkleinert und vom Benutzer durch Vordrücken von Becken und Oberschenkeln vergrößert; anstatt der prinzipiell möglichen Ausführungsform der Fig. 4 ist hier eine Feder F′ eingesetzt, die am Bettgestell S befestigt ist. Die Auflagefläche ist hier nicht durch Latten sondern durch ein elastische Tuch T realisiert, das an den Endlatten des Unterschenkel-Segments U und des Kopf-Segments U′ befestigt ist. Zum Umlenken des Tuches sind an den Enden der Segmente federnde Stangen V bis V′′′ angeordnet. Zusätzlich sind Latten W angeordnet, die bei großen Spannweiten und Belastungen das Tuch abstützen. Benachbarte Segmente sind durch Gelenke X miteinander verbunden, Fig. 8 zeigt dies im Detail. Fig. 7 shows a complete slatted frame with the segments N for lower leg and foot, thigh O, pelvis P, trunk Q and head R. The thigh segment N is shown in variable length, it is enlarged by a spring and by the user Lowering of the lower leg reduced; the embodiment of FIG. 3 with the gas spring E can be used here. The pelvic segment is also shown as variable, it is reduced by a spring and enlarged by the user by pushing forward the pelvis and thighs; instead of the principle possible embodiment of FIG. 4, a spring F 'is used here, which is attached to the bed frame S. The support surface is not realized here by slats but by an elastic cloth T, which is attached to the end slats of the lower leg segment U and the head segment U '. To deflect the cloth resilient rods V to V '''are arranged at the ends of the segments. In addition, slats W are arranged, which support the fabric with large spans and loads. Adjacent segments are connected to one another by joints X; FIG. 8 shows this in detail.

Die dargestellte Anordnung ist mit den weiter oben aufgezeigten Verfahrens- und Vorrichtungs merkmalen zur automatischen bzw. durch den Körperdruck ausgelösten Längenversteilung ausstattbar.The arrangement shown is with the method and device shown above features for automatic length distribution or triggered by body pressure equipable.

Statt einer Ausführung, bei der sämtliche Segmente gegeneinander winkelmäßig verstellbar sind, sind auch Anordnungen möglich, bei der ein oder mehrere Segmente in zueinander fester Winkellage stehen.Instead of an embodiment in which all segments are angularly adjustable relative to each other arrangements are also possible in which one or more segments are in a fixed angular position to one another stand.

Der Rost ist ohne Auflagematratze dargestellt und bei geeigneter Auslegung der Auflageflächen auch ohne weiteres ohne Matratze verwendbar. Die Einstellbedingungen können zur Berücksichtigung dieses Aspektes auch entsprechend der jeweiligen Auflage variiert werden, wobei z. B. der Dicke der Auflageteile Rechnung getragen wird.The grate is shown without a mattress and with a suitable design of the support surfaces can be used without a mattress. The setting conditions can be taken into account this aspect can also be varied according to the respective edition, z. B. the thickness of the Support parts is taken into account.
