Abstract

Przedmiotem zgłoszenia jest mechanizm samohamujący rolety, który charakteryzuje się tym, że środkowa część walcowego elementu (1) umieszczona jest wewnątrz skrętnej sprężyny (5), której jeden koniec (5') osadzony jest w spiralnym kanałku tulejowej części tulei zewnętrznej (4), a drugi jej koniec umieszczony jest w otworze usytuowanym w bocznej powierzchni środkowej części walcowego elementu (1) obok jego końca, który zakończony jest zatrzaskowymi ząbkami, przy czym koniec walcowego elementu (1) ma wykonane wybranie (9), a za nim pierścieniowe odsadzenie z co najmniej jednym wyjęciem i łukowym wypustem, za którymi na środkowej części tego walcowego elementu (1) wykonany jest obwodowy kanałek pod zagięcia odsadzeń tulejowej części tulei zewnętrznej (4), a ponadto na końcu walcowego elementu (1) osadzona jest tuleja wewnętrzna (3), której wewnętrzne czoło ma wykonane co najmniej jedno wyjęcie pod wypust (T2) pierścieniowego odsadzenia walcowego elementu (1) i co najmniej jedno łukowe odsadzenie pod wyjęcie tego odsadzenia, a na bocznej zewnętrznej powierzchni tulei wewnętrznej (3) osadzona jest tuleja zewnętrzna (4) z pierścieniowym zewnętrznym kołnierzem na zewnętrznym jej czole, za którym na zewnętrznej powierzchni jej tulejowej części wykonane są równolegle usytuowane względem siebie podłużne rowki, a na jej tulejowej części wykonany jest spiralny kanałek, zaś czoło tulejowej części posiada wyjęcia i odsadzenia z zagięciami, przy czym długość [L4] osiowego otworu tulejowej części tulei zewnętrznej (4) jest co najmniej równa sumie długości [L3] środkowej części tulei wewnętrznej (3) i dwukrotności długości [L1] wyjęć pierścieniowego odsadzenia walcowego elementu (1) [L4 ≥ L3 + 2*L1].The subject of the application is a self-locking mechanism for a roller blind, which is characterized in that the central part of the cylindrical element (1) is placed inside a torsion spring (5), one end (5') of which is mounted in a spiral channel of the sleeve part of the outer sleeve (4), and its other end is mounted in an opening located in the side surface of the central part of the cylindrical element (1) next to its end, which is terminated with snap-in teeth, wherein the end of the cylindrical element (1) has a recess (9) and behind it an annular shoulder with at least one recess and an arc-shaped projection, behind which a circumferential channel is made on the central part of this cylindrical element (1) for the bends of the shoulders of the sleeve part of the outer sleeve (4), and furthermore, at the end of the cylindrical element (1) an inner sleeve (3) is mounted, the inner face of which has at least one recess for the projection (T2) of the annular shoulder of the cylindrical element (1) and at least one arc-shaped projection a shoulder for removing this shoulder, and on the lateral outer surface of the inner sleeve (3) an outer sleeve (4) is mounted with an annular outer collar on its outer front, behind which on the outer surface of its sleeve part there are longitudinal grooves arranged parallel to each other, and on its sleeve part there is a spiral channel, and the front of the sleeve part has recesses and recesses with bends, wherein the length [L4] of the axial hole of the sleeve part of the outer sleeve (4) is at least equal to the sum of the length [L3] of the central part of the inner sleeve (3) and twice the length [L1] of the recesses of the annular cylindrical shoulder of the element (1) [L4 ≥ L3 + 2*L1].
