Abstract: The invention relates to an access lock for the cyclical opening up of a passageway, with a movable support element, the movement of which is transmitted to an arrangement of locking elements which are movable by means of movement of the support element within guide elements, which delimit the passageway, wherein the support element in each case has one or more first and active surfaces which face in opposite directions, and with a locking device for blocking the movement of the support element, the locking device having two bolts which are movable between a locking position and a release position, wherein a first of the bolts in the locking position thereof, bears against the first active surface or against one of the first active surfaces, and the second bolt, in the locking position thereof, bears against the second active surface or against one of the second active surfaces.

Abstract: The invention relates to an access lock for cyclically permitting people to pass through. The access lock has at least two locking elements (12, 14), with each of the locking elements (12, 14) being movable, independently of the respective other locking element (14, 12), on a closed path between a locked position which locks the passage at a locking point and an open position which opens the passage.

Abstract: The invention relates to a method for operating a turnstile for the cyclical release of a passageway, wherein the turnstile comprises a control unit having a data memory and a data processing unit and comprising at least one blocking element that moves between a blocking position that blocks the passageway at a blocking point and a pass-through position that releases the passageway, wherein the at least one blocking element is connected to a moving support (10) in at least one direction of motion, the support comprising a first active surface (16a) or a plurality of first active surfaces (16a), wherein the turnstile comprises a locking device with at least one locking bar (18, 20) that can move between a first and a second end position and is intended to sit against the first active surface (16a) or one of the first active surfaces (16a) in one of its end positions.

Abstract: The invention relates to an access lock (50, 60) for the cyclical opening up of a passageway, with a movable support element (14), the movement of which is transmitted to an arrangement of locking elements (52, 62) which are movable by means of movement of the support element (14) within guide elements (54, 64), which delimit the passageway, wherein the support element (14) in each case has one or more first and active surfaces (18, 20) which face in opposite directions, and with a locking device for blocking the movement of the support element (14), the locking device having two bolts (22, 24) which are movable between a locking position and a release position, wherein a first of the bolts (22) in the locking position thereof, bears against the first active surface (18) or against one of the first active surfaces (18), and the second bolt (24), in the locking position thereof, bears against the second active surface (20) or against one of the second active surfaces (20).

Abstract: The invention relates to a gate for persons for cyclically opening a passage having at least one blocking element connected to a moveable carrier element and moveable from a blocking position blocking passage at a blocking site into a passage position allowing passage, having a blocking device for blocking the movement of the carrier element comprising at least one bar (18, 20) contacting a working surface (16) of the carrier element at least one contact point in a blockage position, the bar (18, 20) being moveable from the blockage position into an open position, the movement thereof at the contact point taking place in a first direction of motion, and the working surface (16) moving in a second direction of motion at the contact point when the carrier element moves.
