Im Patent Nr. 268589 ist eine Bespannung für Liege- Sitz- und Stützflächen aller Art geoffenbart, deren Trag-oder Stütz-bzw. Federelemente in ihrem elastischen Widerstand mittels einer Spannvorrichtung auf verschiedene Belastungsgrössen einstellbar sind. Ein besonderes Kennzeichen der Bespannung nach dem Patent Nr. 268589 besteht darin, dass sie aus stab-, band- oder flächenförmigen mittels einer eigenen vom Liege-, Sitz-, oder Stützrahmen unabhängigen Spannvorrichtung einzeln oder in Gruppen auf verschiedene Belastungsgrössen in sich spannbaren Federelementen besteht, die innerhalb der Liege-, Sitz- oder Stützfläche entweder in Abständen nebeneinander reihenweise oder gitter-bzw. fächer-, stern-, geflechtartig usw. angeordnet und gegebenenfalls in diesen Formen mit einer bestehenden Bespannung oder Polsterung usw.
kombiniert sind, wobei die Federelementreihen aus mindestens einem flexiblen Zugelement mit einem Endanschlag oder einer Verankerung und einer Reihe auf diesem Zugelement aufgereihter Druckelemente bestehen, welche durch eine am Zugelement angreifende Spannvorrichtung unter einen axialen veränderbaren Druck setzbar und dadurch auf den jeweils erwünschten elastischen Widerstand einstellbar sind.
Es ist bekannt, bei einem zusammenrollbaren und straff ausspannbaren Trag-Stütz-oder Zugelement, das aus aneinandergereihten und auf ein Zugelement aufgefädelten Druckgliedern besteht, auch solche zu verwenden, deren Stirnflächen miteinander einen Winkel einschliessen. Durch Verwendung derartiger keilförmiger Druckglieder wird unter anderem ein starrer, tragfähiger und gekrümmter Stock gebildet. Die Druckglieder greifen dabei mit Vorsprüngen in Ausnehmungen benachbarter Druckglieder und sind dadurch im verspannten Zustand gegen gegenseitiges Verdrehen gesichert. Die so gekuppelten Druckglieder gelangen jedoch im ungespannten Zustand ihres Trägers mit ihren Kupplungselementen ausser Eingriff und können sich gegeneinander verdrehen.
Wird darauf der Träger wieder gespannt, so befinden sich die verdrehten Druckglieder in einer Lage, in der ihre Kupplungselemente nicht mehr zusammenarbeiten können, wodurch die Funktion des gesamten Tragelementes in Frage gestellt ist.
Die Erfindung schafft demgegenüber bei einer Bespannung nach dem Patent Nr. 268589, deren Druckelemente zusätzlich mindestens teilweise im Längsschnitt keilförmig ausgebildet, gegen gegenseitige
EMI1.1
wirkungsvollere Sicherung der Druckelemente gegen Verdrehung als bisher erreicht u. zw. gleichgültig, ob die Druckelemente aneinandergepresst oder lose auf ihrem Zugelement sitzen.
Der Erfindungsgegenstand ist in der Zeichnung an Hand eines Ausführungsbeispieles näher veranschaulicht, die einen Vertikalschnitt einer bevorzugten Ausführungsform des Erfindungsgegenstandes in vergrössertem Massstab zeigt.
Der Zeichnung ist zu entnehmen, dass wie beim Patent Nr. 268589 ein Zugelement --64-- vorgesehen ist, das von einer Schraubenfeder--65--umgeben ist, auf der die einzelnen Druckelemente --66-- sitzen.
Jedes zweite (--67, 68, 69--) dieser rohrstückartigen Druckelemente ist mit zueinander keilförmig verlaufenden Stirnflächen versehen, so dass diese beim Zusammenpressen der Druckelemente an den benachbarten Stirnflächen der zylindrisch gestalteten Druckelemente zur Anlage kommen. Dabei erfolgt bei Spannung der Druckelementreihe eine Krümmung derselben im Sinne der eingezeichneten Pfeile, wobei sich auch das vorhandene Hüllmaterial--70--, z. B. Schaumstoff, mitkrümmt.
Um zu verhindern, dass sich die keilförmigen Druckelemente--67, 68, 69--innerhalb des Hüllmaterials --70-- verdrehen, weisen sie erfindungsgemäss radial abstehende Vorsprünge auf, die beim Ausführungsbeispiel der Erfindung Ringe--71, 72, 73--darstellen. Diese sind auf der in der Zeichnung nach unten weisenden Seite schmäler als an den übrigen Stellen des Umfangs.

<Desc / Clms Page number 1>
In patent no. 268589 a covering for reclining, sitting and supporting surfaces of all kinds is disclosed, the carrying or supporting or. Spring elements are adjustable in their elastic resistance by means of a tensioning device to different load sizes. A special feature of the covering according to patent no.268589 is that it consists of rod, band or flat spring elements that can be tensioned individually or in groups to different load sizes by means of their own tensioning device independent of the lying, seat or support frame , which within the lying, sitting or support surface either at intervals next to one another in rows or in a grid or. Fan, star, braid, etc. arranged and, if necessary, in these forms with an existing covering or upholstery, etc.
are combined, wherein the spring element rows consist of at least one flexible tension element with an end stop or an anchorage and a row of pressure elements lined up on this tension element, which can be set under an axially variable pressure by a tensioning device acting on the tension element and thus adjustable to the respectively desired elastic resistance .
It is known to also use those whose end faces form an angle with one another in a rollable and tautly stretchable support, support or tension element, which consists of pressure members strung together and threaded onto a tension element. By using such wedge-shaped pressure members, a rigid, stable and curved stick is formed, among other things. The pressure members engage with projections in recesses of adjacent pressure members and are thereby secured against mutual rotation in the tensioned state. The pressure members coupled in this way, however, come out of engagement with their coupling elements in the untensioned state of their carrier and can twist against each other.
If the carrier is then tensioned again, the twisted pressure members are in a position in which their coupling elements can no longer work together, whereby the function of the entire support element is called into question.
In contrast, the invention creates a covering according to Patent No. 268589, the pressure elements of which are additionally at least partially wedge-shaped in longitudinal section, against each other
EMI1.1
more effective securing of the pressure elements against rotation than previously achieved u. it is irrelevant whether the pressure elements are pressed against one another or sit loosely on their tension element.
The subject of the invention is illustrated in more detail in the drawing using an exemplary embodiment, which shows a vertical section of a preferred embodiment of the subject of the invention on an enlarged scale.
The drawing shows that, as in patent no.268589, a tension element --64-- is provided, which is surrounded by a helical spring --65 - on which the individual pressure elements --66-- sit.
Every second (--67, 68, 69--) of these tubular pressure elements is provided with mutually wedge-shaped end faces, so that when the pressure elements are pressed together they come to rest on the adjacent end faces of the cylindrical pressure elements. In this case, when the row of pressure elements is tensioned, a curvature of the same takes place in the sense of the arrows drawn, whereby the existing covering material - 70--, e.g. B. foam, also curved.
In order to prevent the wedge-shaped pressure elements - 67, 68, 69 - from twisting within the wrapping material --70 -, according to the invention they have radially protruding projections which, in the exemplary embodiment of the invention, form rings - 71, 72, 73 - - represent. These are narrower on the side facing downward in the drawing than at the other points of the circumference.
