Description

  

  Federndes Untergestell für     Matratzen    und Möbelpolster.    Die Erfindung betrifft ein     federndes     Untergestell für Matratzen und Möbelpolster,  welches man auseinandernehmen kann. Das  Gestell besteht aus     einem    aus Eisenstäben  lösbar zusammengefügten     untern    und obern  Teil, von welchen der obere am untern Teil  auf-     und        abbeweglich    geführt und ,gegen die  sen abgefedert ist.  



  Das Untergestell ist auf der     Zeichnung     durch mehrere     Ausführungsbeispiele    veran  schaulicht.  



  Es zeigen     Fig.    1, 2 und 3 den     Grundriss,     Aufriss und     Seitenriss    eines aus Eisenröhren  zusammengesetzten Untergestelles.     Fig.    4       zeigt,die        Befestigung    der Stahlfedern an den  Gurten mittels Stoffbändchen.     Fig.5,    6, 7  und 8     stellen    verschiedene, aus Flacheisen       zusammengesetzte        Untergestelle    dar.  



  Beim ersten     Ausführungsbeispiel        weist     der untere Gestenteil Längsstangen a in       Eisenröhrenform    auf, welche am Ende recht  winklig umgebogen sind.     Querstangen    b des  obern Teils sind an den Enden ebenfalls  rechtwinklig umgebogen. Dieselben greifen    über die Enden der untern Längsstangen, so  .dass der obere     Gestellteil    am untern auf- und       abbeweglich    geführt ist.

   Die     Verbindungs-          stangen    c aus Flach- oder Rundeisen ergän  zen die mit ihnen verschraubten Längsstan  gen     a    zu einem Rahmen für die untern Gur  ten     g,    während die Hanf- oder Drahtseile d  mit den Querstangen b einen Rahmen für  die obern Gurten g     bilden.    Diese Seile d  sind durch Ösen f der Querstangen hindurch  geführt, ebenso die weiteren Verbindungs  stangen e, welche vermeiden, dass ,sich die  .den obern-     Gestellteil    ,gegen den untern ab  stützenden Stahlfedern i nach aussen ver  biegen.

   Die Gurten g sind an den Enden       mittels        Laschen    verschiebbar an den Gestell  stangen     befestigt.    An den     Gurten        sind    ferner  Stoffbändchen h angenäht, um die Stahl  federn i daran zu befestigen, so wie dies  in ,der     Fig.    4     gezeigt        ist.     



       Fig.    5     zeigt    ein     Ausführungsbeispiel,    bei  welchem die     Gestellteile    am Kopf- und Fuss  ende durch Flachfedern     kgegeneinander    ab  gestützt sind.     Dabei    bestehen die Längs- und      Querstangen aus Flacheisen; an     .den    Quer  stangen b sind die Flachfedern     durch     Schrauben     l    befestigt.  



  Nach     Fig.    6 sind die     Querstangen    b der       Gestellteile    in der     Mitte    durch     .eine    Längs  stange -     7n    verbunden. Dabei sind an die  Enden der Längsstange zwei Eisenschlau  fen n angeschraubt, mit welchen sie die  Querstangen umfasst.  



  Nach     Fig.7    und 8 sind die beiden     Ge-          stellteile    dadurch aneinander geführt, dass an  den     gegeneinander    abgebogenen Enden der  Stangen Schlitze o angebracht sind, in wel  chen     Stifte    p verschiebbar sind, die an den  Enden     Muttern    aufweisen.  



  Alle Ausführungsbeispiele haben den  Vorteil gegenüber den bekannten Unter  gestellen,     @dass    sie zwecks     Zügelns    und Putzens  leicht und schnell auseinandergenommen wer  den können.



  Spring-loaded base for mattresses and furniture upholstery. The invention relates to a resilient base for mattresses and furniture upholstery, which can be taken apart. The frame consists of an iron rods detachably joined together lower and upper part, of which the upper on the lower part is guided up and down and is cushioned against the sen.



  The base is illustrated on the drawing by several exemplary embodiments.



  1, 2 and 3 show the plan, elevation and side elevation of an underframe composed of iron tubes. Fig. 4 shows the fastening of the steel springs to the belts by means of fabric ribbons. Fig. 5, 6, 7 and 8 represent different bases made of flat iron.



  In the first embodiment, the lower gesture part has longitudinal rods a in the shape of iron tubes, which are bent at right angles at the end. Cross bars b of the upper part are also bent at right angles at the ends. The same reach over the ends of the lower longitudinal rods, so that the upper frame part is guided up and down on the lower part.

   The connecting rods c made of flat or round iron complement the longitudinal rods a screwed to them to form a frame for the lower belts g, while the hemp or wire ropes d with the transverse rods b form a frame for the upper belts g. These ropes d are passed through eyelets f of the cross bars, as are the other connecting bars e, which prevent the.

   The straps g are slidably attached to the frame rods at the ends by means of tabs. On the belts fabric tapes h are also sewn to fasten the steel springs i to it, as shown in FIG.



       Fig. 5 shows an embodiment in which the frame parts at the head and foot ends are supported by flat springs kg against each other. The longitudinal and transverse bars are made of flat iron; The flat springs are attached to the cross bars b by screws l.



  According to Fig. 6, the cross bars b of the frame parts are connected in the middle by .eine longitudinal bar - 7n. Two iron loops are screwed to the ends of the longitudinal rod, with which they encompass the transverse rods.



  According to FIGS. 7 and 8, the two frame parts are guided to one another in that slots o are attached to the ends of the rods bent against one another, in which pins p can be displaced which have nuts at the ends.



  All the exemplary embodiments have the advantage over the known sub-frames that they can be easily and quickly taken apart for the purpose of moving and cleaning.
