Description
Federungseinheit
Die vorliegende Erfindung betrifft eine Federungseinheit zur Verwendung in einem Polster.
Es ist bei der Herstellung von Polstern wie z. B. für Betten, Divans, Chaiseslongues, Sofas, Lehnstühlen und dergleichen üblich, eine vorfabrizierte Federungseinheit, deren Achsen parallel zueinander verlaufen, zu verwenden, welche Einheit eine Vielzahl von mit der Hilfe von aus Draht bestehenden Umfangsrahmen, in einer dimensional stabilen Einheit miteinander verbundenen Polsterfedern aufweist. Ein erster derartiger Umfangrahmen ist auf dem äusseren Windungsabschnitt jeder am Umfang angeordneten Feder, an einem Ende dieser befestigt, und ähnlicherweise ist ein zweiter derartiger Umfangsrahmen am anderen Ende jeder am Umfang angeordneten Feder befestigt, wobei die Befestigung der Rahmen an die Federwindungen mittels geeigneter Befestigungsorgane durchgeführt wird.
Die Herstellung der genannten Umfangsrahmen erfordert spezialisierte Verformungsmaschinen, welche zusammen mit der grossen Anzahl der erforderlichen Befestigungsorgane die Herstellungskosten der Vorrichtung in unzulässigem Masse erhöhen.
Ziel der vorliegenden Erfindung ist, durch das Weglassen der Umfangsrahmen und durch die Verwendung von anderen, weniger kostspieligen Methoden, die Herstellungskosten der in Polstern zu verwendenden, zur dimensionellen Stabilisierung der ganannten Vorrichtungen bestimmten Federungseinheiten, herabzusetzen.
Gemäss der vorliegenden Erfindung ist eine Federungseinheit vorgesehen, welche durch eine Vielzahl von untereinander verbundenen Polsterfedern, deren Achsen parallel zueinander verlaufen gekennzeichnet ist, wobei am Umfang der Einheit an entgegengesetzten Enden der Federn Schienen vorgesehen sind, welche die Endwindungen der genannten Federn aufnehmen.
Nachstehend wird eine Ausführungsform des Erfindungsgegenstandes anhand einer Zeichnung noch näher erläutert.
Es zeigt:
Fig. 1 eine schaubildliche Ansicht eines Teils einer erfindungsgemässen Federungseinheit,
Fig. 2 eine schaubildliche Ansicht einer ersten Ausführungsform einer zum Verbinden der Enden der am Umfang der Einheit befindlichen Federn bestimmten Befestigungsschienen,
Fig. 3 eine schaubildliche Ansicht einer zweiten Ausführungsform einer Befestigungsschiene sowie die einer Befestigungsklemme,
Fig. 4 eine schaubildliche Ansicht einer dritten Ausführungsform einer Befestigungsschiene.
Eine, beispielsweise für einen Sitz bestimmte Einheit weist im wesentlichen die Form einer viereckigen Schachtel auf und besteht aus vier parallelen Reihen, von denen jede fünf Polsterfedern 2 aufweist (Einfachheit halber sind in Fig. 1 nur drei Federn gezeigt).
Die Federn 2 sind vertikal angeordnet. Benachbarte Federn jeder Reihe sind bei ihren oberen und unteren Enden mittels von vier oberen und vier unteren, die Reihen überquerenden, gewickelten Drähten (nicht dargestellt) in einer konventionellen Art untereinander verbunden.
Gemäss der Erfindung ist der Umfang der Einheit bei entgegengesetzten Enden der Federn mittels der Schienen 3 gebildet. Acht derartige Schienen sind vorgesehen, um die Endwindungen der am Umfang befindlichen Federn, entlang der acht Kanten der schachgelförmigen Vorrichtung, aufzunehmen und einzugrenzen. Jede der genannten Schienen ist aus synthetischem Kunststoffmaterial nach einem Ausstossverfahren hergestellt und weist einen U-, V-, L-förmigen oder irgendeinen anderen Querschnitt auf, welches die Aufnahme der genannten Endwindungen zwischen den beiden Schenkeln der Schiene ermöglicht.
Die Windungen können entlang der Schienen mit verschiedenen Methoden in Stellung gehalten werden. In einer ersten Ausführungsform (Fig. 2) sind die, die Windungen aufnehmenden Schenkel 3a, 3b der Schienen 3 entlang dieser in voneinander im Abstand angeordneten Stellungen zusammengeschweisst (wie mit 4 angedeutet),um dieEntkuppelung der Schienen 3 von den Federn zu verhindern.
In einer zweiten Ausführungsform (Fig. 3) sind die Schienen 3 an die Windungen mit Metallklemmen 5 befestigt. In einer dritten Ausführungsform (Fig. 4) ist die Befestigung mit dem schraubenförmig entlang der ganzen Länge aller Schienen 3, nach der Aufnahme der Windungen, gewickelten Drahtes gewährleistet.
In einer vierten Ausführungsform (nicht dargestellt) sind die Schienen so ausgebildet, dass die Schenkel eine klemmende Wirkung auf die zwischen ihnen aufgenommenen Windungen ausüben und dass keine zusätzlichen Befestigungsmethoden erforderlich sind.
Suspension unit
The present invention relates to a suspension unit for use in a cushion.
It is used in the manufacture of upholstery such as B. for beds, divans, chaise longues, sofas, armchairs and the like common to use a prefabricated suspension unit, the axes of which are parallel to each other, to use, which unit a plurality of with the help of wire perimeter frames, connected together in a dimensionally stable unit Has upholstery springs. A first such circumferential frame is attached to the outer coil portion of each circumferential spring, at one end thereof, and similarly a second such circumferential frame is secured to the other end of each circumferential spring, the attachment of the frames to the spring coils being carried out by means of suitable fasteners becomes.
The production of said peripheral frames requires specialized deformation machines which, together with the large number of fastening elements required, increase the production costs of the device to an inadmissible degree.
The aim of the present invention is, by omitting the peripheral frames and by using other, less expensive methods, to reduce the manufacturing costs of the suspension units intended to be used in cushions for the dimensional stabilization of the aforementioned devices.
According to the present invention, a suspension unit is provided which is characterized by a plurality of interconnected upholstery springs, the axes of which run parallel to one another, with rails being provided on the circumference of the unit at opposite ends of the springs which accommodate the end turns of the said springs.
An embodiment of the subject matter of the invention is explained in more detail below with reference to a drawing.
It shows:
1 shows a diagrammatic view of part of a suspension unit according to the invention,
2 is a perspective view of a first embodiment of a fastening rail intended for connecting the ends of the springs located on the periphery of the unit;
3 shows a diagrammatic view of a second embodiment of a fastening rail and that of a fastening clamp,
4 shows a perspective view of a third embodiment of a fastening rail.
A unit intended, for example, for a seat is essentially in the form of a square box and consists of four parallel rows, each of which has five cushion springs 2 (only three springs are shown in FIG. 1 for the sake of simplicity).
The springs 2 are arranged vertically. Adjacent springs of each row are connected at their upper and lower ends by means of four upper and four lower coiled wires (not shown) crossing the rows in a conventional manner.
According to the invention, the circumference of the unit is formed by means of the rails 3 with opposite ends of the springs. Eight such rails are provided to receive and contain the end turns of the peripheral springs along the eight edges of the checkered device. Each of said rails is made of synthetic plastic material by an ejection process and has a U-, V-, L-shaped or any other cross-section which enables the said end turns to be received between the two legs of the rail.
The coils can be held in place along the rails by a variety of methods. In a first embodiment (Fig. 2) the legs 3a, 3b of the rails 3 receiving the windings are welded together along these in spaced-apart positions (as indicated by 4) to prevent the rails 3 from being uncoupled from the springs.
In a second embodiment (FIG. 3) the rails 3 are attached to the windings with metal clamps 5. In a third embodiment (FIG. 4), the fastening is ensured with the helically wound wire along the entire length of all rails 3 after the windings have been taken up.
In a fourth embodiment (not shown) the rails are designed so that the legs exert a clamping effect on the turns received between them and that no additional fastening methods are required.
