The invention relates to a security grille system (1) for securing a passage at least partly. The security grille (2) is arranged to be brought from an extended state, in which the grille (2) can block the passage at least partly, into a retracted state, in which at least a part of the previously blocked part of the passage is unblocked. The security grille (2) comprises a multiplicity of bars (4), preferably substantially horizontally extending bars (4), connected by means of multiple elongated connecting elements for interconnecting respective bars (4). The security grille system (1) further comprises a chain connected to the grille (2), preferably a chain being flexible in only one dimension and/or being roller chain, and at least one chain limiting (28) member for at least locally limiting movement of the chain (19), e.g. in a direction in which it is flexible, such as to counteract that one or more links of the chain can be substantially moved away from a regular route along which the links move when the grille (2) is moved from its extended state to its retracted state or vice versa.

A safety guard or gate for placement in a frame of an opening to prevent a child or pet from passing though the opening. The present invention includes an adjustable means for adjusting the guard to fit the width of the frame, wherein the adjustable means has a first end and a second end to form an axis along which the means can be adjusted. The invention further includes an attachment means for securing the guard to the frame; and a securing means for securing the adjustable means to the attachment means. The securing means prevents the adjustable means from disengaging from the attachment means along the axis when in a locked position, and allows disengagement and reengagement of the adjustable means in direction that transects the axis when the securing means is in an unlocked position. The present invention further includes methods for using the safety guard, and systems that include elements of the safety guard.

The inventive door comprises two lateral posts (2), a transversal caisson (3) connecting the top ends of the posts and a curtain (10) movable between the closing position thereof, wherein said curtain closes a void formed by posts (2) and caisson (3) and the opening position wherein said curtain is folded up under the caisson (3). According to the invention, said the curtain (10) consisting of two parallel screens (11a, 11b) defining the boundaries of an air cushion and suspended to the top area of the posts. Said curtain (10) comprises at least one lifting strap (20) connecting the lower part of the curtain (10) to a shaft (21) mounted on the caisson (3) and at least one transversal stiffening means built up on each screen (11a, 11b), the lateral edges of each screen (11a, 11b) are applied to the posts in such a way that a lateral surface tight contact is formed.
摘要:
A device for connecting the flexible curtain of a door and its hauling straps having a mechanism connected to a proximately located horizontal reinforcing bar and with a retention mechanism such as a ring for the retaining the hauling strap. The distance between the horizontal reinforcing bar and the ring varies in association with the location of the bar on the curtain.
摘要:
An adjustable security barrier comprising three sections whose relationship to each other can be adjusted to expand or contract the area covered by the security barrier. The barrier uses hidden wedge nuts, with bolts to secure the sections together. The bolts and nuts are inaccessible when the barrier is in the locked position. A sliding rod is adapted to be inserted into a hole in the passageway so that the barrier can be locked into place by the use of a padlock. Hinged mounting plates allow free swinging motion of the barrier. The hinges and mounts are inaccessible when the barrier is in the locked position.
