The at least one first floor rail arrangement includes at least one first floor rail and at least one connection and/or functional element, wherein the at least one connection and/or functional element is arranged on an end side of the at least one first floor rail. The at least one first floor rail includes at least one first guide groove extending in the longitudinal direction. The at least one engagement element of the at least one first door leaf of the at least one first door leaf arrangement is inserted into the at least one first guide groove and is guided in the longitudinal direction by the at least one first guide groove.

A locking device for locking a first component to a second component, the device having: a catch element for fastening to the first or second component; a latching unit for fastening to the second or first component; the latching unit comprising a release element; and the release element can be moved between a rest position, which arranges the first latching body in the first latching recess of the catch element and in the receiving opening of the release element, and a release position, which releases the engagement between the first latching body and the first latching recess of the catch element.

The disclosure relates to a locking device for locking a first component to a second component having a catch element for fastening to the first or second component, the catch element comprising a first latching recess; having a latching unit for fastening to the second or first component; the latching unit comprising a first latching body for engagement with the at least one latching recess of the catch element; the latching unit comprising a release element which comprises a first receiving opening for receiving the first latching body; and the release element can be moved between a rest position, which arranges the first latching body in the first latching recess of the catch element and in the receiving opening of the release element, and a release position, which releases the engagement between the first latching body and the first latching recess of the catch element.

A slide-and-swing wing system includes at least one rail profile. At least two wings, each displaceably mounted in the at least one rail profile via two support elements The at least one rail profile has a lateral outlet opening for unlatching a support element of a wing. One wing functions as a door leaf which, with all other wings in the latched state, is pivotable into the remaining opening. A closure mechanism makes it possible to prevent the door leaf from being opened and includes a drive, and also an operating part, via which the drive can be actuated. The door leaf is displaceable, via the drive, in the rail profile in the direction of the adjacent wing to such an extent that no support element of the door leaf is aligned with the outlet opening, thereby preventing a support element from coming out through the lateral outlet opening.

A security panel system that is adapted to protect innocent bystanders from gunfire in the event of a shooting. The security panel system includes a main body having a first rail, a second rail, a panel, and a locking mechanism. The first rail and the second rail may each be mounted adjacent to a window and movably secure a panel therebetween. The panel is movable between an opened position and a closed position. The locking mechanism is configured to secure the panel in the closed position. It should be appreciated that, while the panel is in the closed position, the shooter may not be able to see or fire through the window due to use of the security panel system.

In a high-security sliding-door apparatus for closing and opening a corridor, the door having (a) a door frame having a track and a bi-directional effector, (b) a carriage having track-engaging rollers, (c) a slide plate slidably secured to the carriage and driven by the effector, and (d) a controller controlling slide-plate movement and enabling the door to be continuously closed but not locked, the improvement comprising centering apparatus for relative positioning of the slide plate and carriage, the centering apparatus including (1) a yoke attached to the slide plate at a yoke pivot and having a yoke cam surface thereabove, (2) a carriage-attached yoke-cam follower, and (3) springs having proximal ends attached to the yoke spaced above the yoke pivot and distal ends each attached to the carriage at points offset from the yoke pivot in opposite lateral directions, centering the door with the slide plate when unlocked.

The invention relates to an automatic door system including a first door leaf of a first door leaf arrangement that can be displaced in the longitudinal direction. A floor-side guide rail arrangement extends in the longitudinal direction and includes a first floor rail arrangement. The at least one first door leaf includes an engagement element which is arranged on an underside of the at least one first door leaf. The at least one first floor rail arrangement includes at least one first floor rail and at least one connection and/or functional element, wherein the at least one connection and/or functional element is arranged on an end side of the at least one first floor rail. The at least one first floor rail includes at least one first guide groove extending in the longitudinal direction. The at least one engagement element of the at least one first door leaf of the at least one first door leaf arrangement is inserted into the at least one first guide groove and is guided in the longitudinal direction by the at least one first guide groove.

The invention relates to a locking device for locking a first component, in particular a door leaf, to a second component, in particular to a door frame, having a catch element for fastening to the first or second component, the catch element comprising a first latching recess; having a latching unit for fastening to the second or first component; the latching unit comprising a first latching body for engagement with the at least one latching recess of the catch element; the latching unit comprising a release element which comprises a first receiving opening for receiving the first latching body; and the release element can be moved between a rest position, which arranges the first latching body in the first latching recess of the catch element and in the receiving opening of the release element, and a release position, which releases the engagement between the first latching body and the first latching recess of the catch element.
