Abstract

Auksetyczna sprężyna, zwłaszcza do mebli tapicerowanych jaka zawiera osiowo symetryczny szkielet, który w rzutach prostokątnych ma kształt kokardy o bokach tworzących kąty wklęsłe. Szkielet sprężyny zawiera co najmniej cztery osiowo-symetryczne, wklęsłe ramiona. Sposób wytwarzania formatki tapicerskiej z auksetyczną sprężyną, zwłaszcza do mebli tapicerowanych przebiega tak, że w pierwszym kroku wytwarza się pojedyncze sprężyny nadając ich szkieletowi grubość wszystkich ramion od 3 mm do 5 mm, następnie sprężyny łączy się w macierze z wystającymi poziomymi fragmentami ramion (1) sklejając je przy użyciu kleju silikonowego, a uformowane formatki sprężyn auksetycznych umieszcza się na arkuszu filcu o grubości do 5 mm, na którego obwodzie umieszcza się prostopadłościenne ograniczniki wykonane z pianki poliuretanowej o sztywności od 4 do 8 kPa, oraz grubości równej wysokości sprężyny, a na taką konstrukcję nakłada się arkusz filcu o podobnych właściwościach jak arkusz filcu dolnego i przykleja się go do ramki wykonanej z pian poliuretanowych za pomocą kontaktowego kleju dyspersyjnego.Auxetic spring, especially for upholstered furniture, which contains an axially symmetrical frame, which in rectangular projections has the shape of a bow with sides forming concave angles. The spring frame includes at least four axially symmetrical concave arms. The method of producing upholstery mats with an auxetic spring, especially for upholstered furniture, proceeds in such a way that in the first step individual springs are made, giving their skeleton the thickness of all arms from 3 mm to 5 mm, then the springs are combined in the matrix with protruding horizontal arm fragments (1) gluing them using silicone glue, and formed auxetic spring forms are placed on a felt sheet up to 5 mm thick, on the perimeter of which rectangular stops made of polyurethane foam with a rigidity of 4 to 8 kPa, and thickness equal to the height of the spring, and on such a structure is applied a felt sheet with similar properties as the bottom felt sheet and glued to a frame made of polyurethane foams with the help of contact dispersion adhesive.
