Definitions

  • the invention relates to a lock cylinder with pivotable closure, which is arranged behind the cylinder cover and consists of a closure flap, which closes the insertion opening of the key channel and is pivotable about an axis perpendicular to the longitudinal axis of the cylinder, with one end of a torsion spring on the inside of the Key channel facing surface of the closure flap.
  • Closure flap be cocked in the cylinder, and the whole must be held when attaching the cylinder cover that holds the whole.
  • the quality of the protection achieved by a pivotable closure flap requires a simplification of the assembly, which the large series manufacturing at a competitive price.
  • this object is achieved in a lock cylinder of the type mentioned at the outset in that the second end of the torsion spring projects over the outer surface of the lock cylinder before assembly and, after bending, cooperates with a stop connected to the cylinder.
  • the lock cylinder according to the invention therefore enables the torsion spring, the closure flap and the cylinder cover to be assembled without tensioning the spring; the spring is only tensioned after assembly and fastening of the cylinder cover.
  • Fig. 1 is an exploded perspective view of a lock cylinder according to one
  • Figure 2 is a perspective view of the cylinder shown in Figure 1 after assembly, but before tensioning the spring.
  • Fig. 3 is a view similar to Figure 2 of the cylinder, but with the spring tensioned.
  • the lock cylinder in particular a cylinder core, has an enlarged head 2, into which an axial recess 3 is formed, which opens into the key channel (not shown).
  • a closure flap 4 with two side lugs 5 is arranged, which in two off Take 6 in the head 2 of the cylinder are pivotable.
  • a torsion spring 7 rests with one end 8 on the surface of the closure flap 4 facing the key channel.
  • the se helical, cylindrical torsion spring 7 lies with its axis parallel to the flap axis of rotation and how this is perpendicular to the longitudinal axis of the cylinder.
  • a cylinder cover 9 with an opening 10 for passing the key by bending a fastening tab 11 is mounted, which holds the closure flap 4 and the spring 7 in the recess 3.
  • the second end 12 of the spring 7 When assembling the lock cylinder, the second end 12 of the spring 7 is inserted into an outwardly opening axial slot 13 in the front end of the cylinder head 2; this slot opens at one end into the savings 3 and at the other end on the circumference of the head 2.
  • the length of the end 12 of the spring 7 is dimensioned such that this end protrudes approximately radially or parallel to a radial over the circumference of the head 2 (Fig. 2).
  • the assembly can therefore be carried out by successively inserting the spring 7 up to the stop, the closure flap 4 and the cylinder cover 9 parallel to the longitudinal axis of the lock cylinder 1.

Abstract

Le cylindre (1) comporte dans la partie élargie de sa tête (2) un volet de fermeture (4) monté pivotable et qui ferme l'ouverture d'entrée du canal de la serrure. Le bout (8) d'un ressort de torsion (7) s'appuie sur la face du volet (4) située côté canal de la serrure. L'autre bout (12) du ressort de torsion (7) dépasse avant l'assemblage la face externe du cylindre à travers une fente (13) pratiqueé dans la tête (2) du cylindre (1); après le montage, il est recourbé pour coopérer avec une butée (14) solidaire du cylindre (1). Cette disposition du cylindre facilite son assemblage.
