摘要： A hinge has first and second leaf assemblies pivoted on each other and a link assembly interconnecting the first and second leaf assemblies. At least one of the first and second leaf assemblies has upper and lower mounts forming a cavity in which a respective end of the link assembly is pivoted, and at least one of the mounts of the one leaf assembly is formed with a recess opening into the cavity. According to the invention a body of foaming fire-protection material is provided in the recess so that when heated the body expands and fills the cavity with fire-protective foam.

摘要： A door hinge has first and second leaf assemblies. The first assembly is formed with a longitudinal guide groove. First and second links are connected to each other for relative pivoting about a vertical axis. The first link is pivoted in a longitudinally displaceable slide in the groove. This slide has a length longitudinally of the guide groove and a width transversely of the guide groove. The ratio of the length to the width of the slide is at least 2:1.

摘要： A magnetic lock has a magnetically operable latch having a magnetically repellable or attractable latch element. A magnetic operating device spaced from the latch has a first magnet with a respective magnetic direction and a second magnet with a respective magnetic direction. The first magnet is rotatable between a latched position with its magnetic direction generally parallel to and pointing oppositely to the magnetic direction of the second magnet for contracting a magnetic field formed by the first and second magnets, and a release position generally parallel to and with its magnetic direction pointing the same as the second magnet for extending the magnetic field to and repelling or attracting the latch element.

摘要： A door-operating assembly has an operating device having a device housing and a device magnet and rotatable in the housing about a first axis between a first functional position and a second functional position, and a status indicator that is coupled with the operating device and has an indicator housing and an indicator magnet movable in the indicator housing along the first axis between a first display position and a second display position. The magnets are so oriented that rotation of the device magnet about the first axis from the respective first functional position into the respective second functional position displaces the indicator magnet axially of the first axis from the first display position into the second display position.

摘要： A door-operating assembly has first and second subassemblies each having a housing, a magnet, a sleeve carrying the sleeve and rotatable in the respective housing about an axis, an actuator for rotating the first sleeve about the respective axis, and a rotation limiter restricting rotation of the respective sleeve and magnet. The magnets in a first position repel and push the respective sleeves axially away from each other such that the first rotation limiter is effective in a first direction on the first sleeve and the second rotation limiter is effective in a second rotation direction on the second sleeve. Conversely, the magnets in a second position attract and pull the sleeves axially toward each other such that the first rotation limiter is effective against the first rotation direction on the first sleeve and the second rotation limiter is effective against the second rotation direction on the second sleeve.
