Title
(DE) VORRICHTUNG ZUM EINSPANNEN FEUERFESTER PLATTEN IN METALLISCHE RAHMEN VON SCHIEBERVERSCHLÜSSEN.
(EN) DEVICE FOR CLAMPING FIRE-PROOF PLATES IN METALLIC FRAMES OF SHAFT LOCKS
(FR) DISPOSITIF DE SERRAGE DE PLAQUES IGNIFUGES DANS LE CADRE METALLIQUE D'ENCLENCHEMENTS A ARBRES.
Abstract
(EN)
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.

(FR)
Un dispositif de serrage de plaques ignifuges (2) dans le cadre métallique (3) d'enclenchements à arbres comprend une mâchoire de serrage (8) qui peut être pressée contre la périphérie (14) de la plaque et qui est actionnée par une pièce en coin (18) ajustable à cet effet sur le filetage d'un boulon fileté (23) agencé rotatif dans le cadre (3). La pièce en coin (18) s'engage dans la mâchoire de serrage (8) par des rainures de guidage (17, 19). On doit ainsi obtenir un meilleur fonctionnement du dispositif de serrage, en particulier lors du desserrage.
