A protective barrier and a door frame protection system include a bar having an upper section having an outer dimension; a lower section having an inner dimension greater than the outer dimension of the upper section, the lower section configured to receive the upper section; and a shock absorber configured to be positioned within the lower section and around the upper section, the shock absorber having an outer dimension less than the inner dimension of the lower section and an inner dimension greater than the outer dimension of the upper section.

The present invention concerns a motorized door for closing an area (3) at least partially defined by a frame, said Motorized door comprising: (A) a motorized driving mechanism (10) for moving a shutter between an open position (z=1) and a closed position (z=0) in a first direction (α) to close said area defined within said frame and in a second direction (β) to open said area; (B) a detection cell (5, 6) suitable for detecting an accidental event (eI), during the motion of the shutter. The motorized door further comprises a processing unit programmed to trigger a wind related safety function avoiding the yo-yo effect in case strong winds triggered the erroneous detection of an accidental event by the detection cell, said wind related safety function comprising the following steps: (C) a processing unit (CPU): (a) stop the movement of the shutter in the first direction (α), and reverse said movement into the second direction (β) and, after a brief reverse time, Δt, of the order of 0.8 to 3.0 s, (b) stop said movement in the second direction (β) and reverse the movement back into the first direction (α) towards the closed position (z=0) of the shutter.

An opening/closing direction restriction mechanism for a manual shutter device and an opening/closing direction restriction mechanism for a suspended sliding door device. This opening/closing direction restriction mechanism is provided with: a flange fixedly mounted on a fixed shaft; a bracket which is loosely fitted to the fixed shaft and can be integrally rotated with a winding member; and a two-way clutch which can be switched between a reverse rotation inhibited state in which the revolution of a planetary external gear along a winding direction of the winding member is allowed and the revolution of the planetary external gear along an unwinding direction is inhibited, and a forward rotation inhibited state in which the revolution of the planetary external gear along the winding direction of the winding member is inhibited and the revolution of the planetary external gear along the unwinding direction is allowed.

Improvements in the straightness in the vertical plane of a screen panel attached within a rectangular frame structure employing split tubes as its top and bottom edges/struts are described. Areas permitting the straightness of the screen panel to be improved include zip attachment of the screen panel to the split tubes, dependence of teeth orientation, reinforcement of the frame structure using struts, clamping of the split tubes to the frame, and modification of the screen panel, individually or in any combination thereof.
