Inwardly opening tilting door.

摘要

An inwardly opening tilting door, designed to be mounted in a frame (1) fixed inside the entrance or exit of premises, consisting of a single piece (3) and held by two lateral arms (4) which are each fixed at one end to a tab (12) on the door itself and at the other end to a support (7) provided on the upper corners of the frame (1) itself, each arm (4) being pulled by spring (10). A second arm (14) pivots at an intermediate region of each of the arms (4), closer to the end which pivots on the support (7), said arm (14) sliding in and being guided by a loop (15) fixed to the frame (1) and being pulled by a spring (18) fixed to the corresponding support (7). The door slides by means of rollers (5) in channels defined by vertical shapes (2) joined to the frame (1), the spring (18) acting such that it constantly tends to open the door (3).
