  • the outer contact end of the cursor 4 is preferably made tapered like a wedge or with a V-shape and has a rounded apex both around an axis perpendicular to the plane subtended by the V-shaped section and according to an axis parallel to said plane, in this case the curvature radius being relatively big so that the arch of the apex is flatter with respect to that around the axis perpendicular to the plane subtended by the V-shaped section .
  • the cursor 4 , the corresponding guide and the spring are advantageously housed in the lock case 1 and the cursor protrudes out through a matching cutout of the front side of said case.
  • the spring 3 is made by a leaf which has a V or L shape by making an electrically conductive contact surface with the conductive core of the radial pin locking the core 17 in the sheath 21 and in the rod 14 and making an electric contact with said core 17.
  • the cursor 4 cooperates with its free end with an electrically conductive contact surface formed by a plate 20 which, in the illustrative embodiment, is shaped as a channel with rectangular section and which is supported on the stop plate 18 of the jamb by a frame made of material electrically insulating and resistant to high temperatures, such as for example ceramic porcelain.
  • Said frame 19 is fastened on the back side of the stop plate 18 and is provided with threaded holes passing through two opposite sides of the same, in which threaded grub screws which penetrate with the tips into corresponding notches of the two upper and lower transverse walls of the contact terminal with channel-like section 20 can be engaged.
  • An embodiment variant provides that the plate 20 and the corresponding frame have circular shape.
  • the hole for fastening the frame and the plate 20 can be easily made by using a drill bit of suitable diameter, whereas a non-round shape would require more complex and long operations than only making the hole.

Abstract

L'invention concerne une combinaison d'au moins une, de préférence deux ou plusieurs poignées lumineuses. Chaque poignée (6) desdites deux poignées comprend un élément de prise (66) qui, pour au moins en partie, est constitué d'un élément de lampe (12). La source lumineuse de chaque poignée peut être commandée pour émettre le rayonnement lumineux avec une fréquence prédéterminée indépendamment des sources des autres poignées. L'invention concerne un dispositif de fermeture d'accès comprenant un élément de paroi mobile pouvant se déplacer vers une position coïncidant avec l'ouverture de passage dudit accès et à une position au moins partiellement décalée par rapport à l'ouverture de passage dudit accès, ledit élément de paroi mobile étant pourvu de ladite combinaison de poignée lumineuse et/ou d'une ou de plusieurs lampes combinées aux faces dudit élément de paroi mobile. L'invention comprend également un système d'alarme incendie doté d'au moins une porte coupe-feu, ladite porte comportant au moins un vantail muni de ladite combinaison de poignée lumineuse et/ou une ou plusieurs lampes combinées aux faces dudit vantail.
