Abstract

Cijev iz polimernog materijala za prihvat uvlačnih elemenata kao što su kabeli (2, 3), optički kabeli, cijevi i slično, pri čemu unutarnji opseg cijevi ima rebrastu strukturu stvorenu pomoću utora, naznačena time, da je unutarnji glatki opseg cijevipodijeljen aksijalno na djelomične segmente (11),pri čemu djelomični segmenti (11) tvore djelomična područja s glatkom unutarnjom površinom cijevi, tako da oni ne tvore nikakav šiljasti ili zaobljeni rebrasti oblik, koji su međusobno odvojeni pomoću utora (12) raspoređenih aksijalno između djelomičnih segmenata (11), a koji su kao takovi poznati,tako da se kod prodiranja upuhanog komprimiranog zraka ispod uvučenih elementa, kao što su kabeli (2, 3), optički kabeli, cijevi i slično, stvaraju zračni jastuci, i pri čemu omjer dimenzija između djelomičnih segmenata (11) i utora (12) iznosi između 1,5:1 do 5:1. Patent sadrži još 3 patentna zahtjeva.A tube made of polymeric material for receiving retractable elements such as cables (2, 3), optical cables, pipes and the like, wherein the inner circumference of the tube has a ribbed structure created by means of grooves, indicated by the fact that the inner smooth circumference of the tube is divided axially into partial segments (11), where the partial segments (11) form partial areas with a smooth inner surface of the tube, so that they do not form any pointed or rounded rib shape, which are separated from each other by grooves (12) arranged axially between the partial segments (11), and which are known as such, so that when blown compressed air penetrates under the retracted elements, such as cables (2, 3), optical cables, pipes and the like, air cushions are created, and the ratio of dimensions between partial segments (11 ) and the slot (12) is between 1.5:1 and 5:1. The patent contains 3 more patent claims.
