Problems solved by technology

But this solution usually brings about the problem that, while expanding the width of the coverage, one must also live with the fact that the constant forward movement is not in the direction of the slide but in the direction of the circular expansion , so that the front edge of the locking element must be continuously guided downwards, since the element is moving in an arc around the pivot axis

Embodiment Construction

[0020] FIG. 1 shows a passage locking device 1 according to the prior art, namely with a simple sliding door leaf 2 . The base support as the arrangement is provided with a support 3 on which the swing arm 4 and the support arm 15 are articulated. The ends of the swing arm 4 and the support arm 15 both engage in the region of the holding rail 14 to which the sliding door leaf 2 can be fastened. For the sake of clarity, the sliding door leaf is not shown in FIG. 1 . The swing arm 4 has an elongated hole into which the snap-in element of the swing lever 5 snaps. The pivot lever 5 is rotated by the drive device 20 , which then rotates around its drive axis along a semicircular path. FIG. 1 shows the arrangement according to the prior art in the closed state, ie the sliding door leaf 2 has been moved out into the passage path. When the pivot lever 5 is actuated by the drive 20 , the pivot lever first pivots downwards and then moves in the direction of the open position. In thi...

Abstract

Known passage barriers, such as the type which comprise a sliding door with sliding leaves, can be displaced back and forth between an open and a closed position. Said type of passage barriers are often installed next to each other in a large number in entrances of public buildings, in stadiums or event halls. Due to the fact that the siding doors need to be moved completely from the passage when in the open position, the sliding leaf needs to be as small possible in order to open the through-passage as much as possible. The aim of the invention is provide a passage barrier having a narrow sliding leaf which can block the passage to a large extent. To this aim, the claimed passage barrier comprises a sliding leaf on which an additional rotatable leaf is articulated on a rotational leaf axis. The rotating leaf enters into the passage and widens with the sliding leaf in a manner parallel to the withdrawal of the sliding leaf.

Description

technical field [0001] The invention relates to a passage blocking device, which has a fixed support, relative to which a sliding door leaf can be moved at the same time by the simultaneous movement of at least two points of action distributed in the length direction of the sliding door leaf. Shifts between an open position and a closed position. Background technique [0002] Such a channel blocking device is known from German patent application 102008025757A1. Access locks of this type can be used, for example, in the entrance area of ​​public buildings, stadiums or also in conference halls. Depending on the design variants, various sliding door leaves can also be used here. In particular, the sliding door leaf, which is considered to be of high value here, moves out of the area of ​​the passage in a straight line on the most direct possible path and likewise closes the area of ​​the passage again in a straight line as possible. Until now, such an operation was usually c...
