Abstract (en)
[origin: WO8803069A1] For clamping fire-proof plates (2) in the metallic frame (3) of shaft locks, a device is disclosed having a clamping jaw (8) that can be urged against the periphery (14) of the plate and actuated by a wedge (18) adjustable for this purpose on the thread of a threaded bolt (23) rotatively arranged in the frame (3). The wedge (18) engages the clamping jaw (8) over guide-ways (17, 19). An improved operation of the clamping device should thus be possible, in particular during unclamping.
