Definitions

  • the invention relates to a cylinder lock, which can find application in the field of light industry, especially in the field of the locking devices with high security for residential houses, public and other buildings, cabinets, safes, and others where is required high burglary resistance.
  • the typical double cylinder lock comprises a housing with inner and outer cylinder cores mounted therein, said housing is suitable to be mounted transversely through the lock box, as between both cylinder cores in the housing there is freely mounted rotating cam to drive the elements of the lock.
  • the said cam represents a solid ring ;
  • This part of the housing is usually the thinnest and therefore the weakest, because it is suited to accommodate the rotation of the said cam. If this part of the housing can be broken, then the entire outer half of the cylinder lock can be removed, unless there were taken specific measures in the construction of the cylinder lock to resist this threat.
  • Cylinder lock is known from EP 0759492, where both cylinder cores are protected against withdrawal by special cam construction, consisting of two parts fixed each other and covering the inner edges of both cylinder cores, which makes pulling of both cylinder cores impossible when applying axial force.
  • both cam parts In the area of the ring both cam parts have engaging grooves which are longitudinally situated to the cylinder lock, as the groove in the first part is formed on the outer cylindrical surface of the ring, and in the second part - on the inner cylindrical surface.
  • the groove in the cam's first part is inversely realized, so that the cam's second part passing over the first part couples therein forming closed ring, which by its protruded inwards periphery covers the inner edges of both cylinder cores through respective ring channels formed therein.
  • the cam is cross divided into two parts, so that by their fixing each other by means of a spring pin passing through the longitudinal holes in the tooth, they form an entire cam.
  • the inner cylindrical surface of the second engaging part of the cam in the tooth area is extended outwards in order to facilitate the assembly.
  • Said cylinder lock has a disadvantage - shaping of both composite parts of the cam requires additional milling, lathe and other operations, which increases the cost and complicate the assembly procedure.
  • the present invention seeks to provide a cylinder lock, resistant to the above mentioned attacks by providing an axial connection of both cylinder cores of the cylinder lock by means of a composite cam with simple and effective technological design that ensures easy installation and lower costs for the cam production.
  • cylinder lock with a composite cam consisting of two parts, which in assembled state represents a ring with a tooth as the said parts are fixed each other, at first in the ring area, so that form the closed ring which by its protruded inwards periphery covers the inner edges of the cylinder cores of the cylinder lock through respective ring channels and second - in the area of the tooth, where the said parts are connected each other by spring pin passing through the longitudinal holes formed therein, so that complimenting each other the parts form an entire cam rotated through a switch transmitting to the cam the rotary motion of respective cylinder core by the right key inserted therein.
  • the said parts of the cam are identical while assembling they are mirror symmetrical to the cam axis, whereby in the area of the ring both parts are interlocked around a transmitting plate by means of two identical locking teeth formed thereon, that engage in respective radial holes formed in the parts of the cam whereby after the parts interlocking both locking teeth are arranged symmetrically to the axis of the cam.
  • the locking tooth has front radial surface for fixing upon the radial hole and back surface which passes smoothly towards the outer surface of the transmitting plate, in order to facilitate the installation.
  • a profile hole in the transmitting plate to engage with the switch, through which there is transmitted rotary motion from the respective cylinder core to the cam.
  • a channel covering the transmitting plate by interlocking of both parts of the cam.
  • the radial hole and the said channel are realized in the respective part of the cam symmetrically to the central plane passing through the cam axis.
  • the advantage of the cylinder lock with a composite cam in accordance with the invention consists in that the said cam providing axial ly connection of both cylinder cores is an assembly of two identical parts which reduces its production cost.
  • both parts' interlocking proposed in the construction facilitates the assembly of the cam at first, and second - makes the construction technological effective, as the transmitting plate which realize the interlocking serves at the same time also for transmission of the rotary motion from the cylinder core to the cam.

Abstract

L'invention porte sur une serrure à cylindre possédant une came composite et qui est applicable au domaine de l'industrie légère, spécialement au domaine des dispositifs de verrouillage de haute sécurité pour les maisons résidentielles, les bâtiments publics et autres bâtiments, les armoires, coffres-forts et autres objets. La came composite (1), qui est composée de deux parties identiques (4), représente à l'état assemblé un anneau (2) possédant une dent (3). Les parties (4) de la came (1) sont verrouillées l'une à l'autre, en premier lieu autour d'une plaque de transmission (5) qui est engagée, par des dents de verrouillage (6), dans des trous radiaux (10) des parties (4), de sorte qu'elles forment l'anneau fermé (2), lequel, par sa périphérie en saillie vers l'intérieur, couvre les bords intérieurs de noyaux de cylindre (15, 16) de la serrure à cylindre au moyen de canaux annulaires respectifs (18). En second lieu, les deux parties (4) sont assemblées l'une à l'autre dans la région de la dent (3) par une goupille élastique (13) qui passe à travers des trous longitudinaux (14) formés dans ces parties, de telle sorte que, en se complétant mutuellement, les parties (4) forment une came complète (1) qui tourne sous l'action d'un commutateur (17), par la rotation de l'un des noyaux de cylindre (15, 16).
