Definitions

  • the invention relates to an electromechanical cylinder lock, especially a lock with rotatable locking discs, in accordance with the preamble of claim 1.
  • An aim of this invention is to provide a new improved electromechanical cylinder lock, which has an uncomplicated construction and from which the drawbacks appearing in the known techniques are eliminated.
  • the lock is provided with at least one locking element, which is movable substantially in the radial direction with respect to the inner cylinder from a locking position, in which the locking element is partly located in a recess or the like arranged in the inner cylinder and partly in the lock housing preventing turning of the inner cylinder with respect to the lock housing, into a releasing position of the inner cylinder and vice versa.
  • the lock includes a second locking element movable substantially in the longitudinal direction of the lock housing and which under the influence of the solenoid means is arranged to control radial movements of said first locking element.
  • the second locking element can, with advantage, be an armature member of the solenoid means, or a member operably connected thereto, which under the influence of the solenoid means is arranged to allow movement of said first locking element into a position releasing the inner cylinder.
  • the lock housing is with advantage provided with a channel extending in the longitudinal direction of the inner cylinder one end of which longitudinal channel is connected with a transverse channel extending towards the inner cylinder.
  • the first locking element comprises a number of balls, whereby a separate ball is provided for cooperation with the second locking element and with the inner cylinder, respectively.
  • the locking elements can, in their locking position, with advantage be arranged on the one hand to allow turning of the locking discs by means of the key of the lock into the position for releasing the lock mechanism and on the other hand to prevent turning of the inner cylinder with respect to the lock housing.
  • this makes picking of the lock mechanism more difficult, because in the lock type in question when the lock mechanism is in its releasing position the inner cylinder has to be turned a bit further so that the groove in the lock housing would press the locking bar itself into a position finally releasing the inner cylinder.
  • both the actual lock mechanism and the locking means depending on electric control simultaneously prevent turning of the inner cylinder with respect to the lock housing, which will effectively prevent any attempt to break the lock.
  • FIG. 1 indicates a lock housing of the cylinder lock, inside of which there is an inner cylinder 2 enclosing a stack of locking discs 3 turnable with the key 19 of the lock.
  • Figure 2 shows in addition a locking bar 15 included in the locking mechanism and which, in the locked position, is located partly in a groove 16 in the lock housing 1 and partly in a slot 17 in the inner cylinder 2, thereby preventing turning of the inner cylinder 2 with respect to the lock housing 1.
  • the inner cylinder 2 can be released to turn with respect to the lock housing 1 by turning the locking discs 3 by the key 19 of the lock into a position, in which the peripheral notches 18 included therein line up at the position of the slot 17 to create a uniform channel, into which the locking bar 15 is free to move when pressed thereinto by a bevelled surface 16a in the groove 16.
  • the operation of this kind of cylinder lock with rotatable locking discs is known as such and it is deemed unnecessary to describe it here in any more detail.
  • a solenoid unit 4 Projecting outwardly of the lock housing 1 is a solenoid unit 4 including a solenoid 5, a channel 10 extending in the longitudinal direction of the lock housing and a channel 11 connected thereto and extending in the radial direction with regard to the inner cylinder 2.
  • the solenoid 5 includes a coil arrangement 6 and an armature member 7, which is urged by a spring 8 towards the channel 11.
  • a wire 9 is provided for feeding electric current to the coil arrangement 6.
  • the armature member 7 serves as a locking member movable in the channel 10 extending in the longitudinal direction of the lock housing under the influence of the solenoid 5 and the spring 8 and acts on a locking element 13 located in the radial channel 11.
  • the locking element 13 constitutes a set of balls, preferably made of steel, and here shown as three in number. Using three balls means that a separate ball is provided for cooperation with the inner cylinder 2 and the armature member 7, respectively.
  • the member 7 has the same diameter as one of the balls and its rounded end simulates half a ball.
  • the inner cylinder 2 is provided with a recess 14 arranged to cooperate with the locking elements 7 and 13 so that turning of the inner cylinder 2 with respect to the lock housing 1 can be controlled by means of the solenoid 5 independently of the actual locking mechanism 3 and 15-18 of the lock.
  • the line of balls 13 prevents the locking bar 15 from moving into the notches 18 in the discs 3, since the bar 15 does not receive the necessary urging from the bevelled surface 16a, into its releasing position in which the locking bar 15 is partly located in the slot 17 in the inner cylinder 2 and partly in the channel formed jointly by the peripheral notches 18 in the locking discs 3.
  • the balls 13 and the locking bar 15 together prevent effectively any attempt at a forced turning of the inner cylinder 2 for the purpose of breaking the locking elements 13.
  • Figure 3 shows the situation where there is no voltage applied to the solenoid 5.
  • the inner cylinder 2 has been turned causing the balls 13 to move further into the channel 11 radially away from the inner cylinder 2, the armature member 7 being pushed to the left against the force of the spring 8 by urging from the balls to make room for them in the radial channel 11.
  • turning of the inner cylinder 2 merely takes place against the force of the spring 8 and once this has been overcome, the inner cylinder 2 can turn with respect to the lock housing 1.
  • a single elongate locking element with rounded ends could be used.
  • the actual solenoid arrangements can be implemented in many different ways, for instance so that the coil 6 does not directly act on a locking element movable in the channel 10.
  • some form of coupling may be arranged between the armature member of the solenoid and the locking element for resisting the forces possibly transmitted via the balls 13, whereby a weaker and, thus, also less expensive solenoid could be used.
  • the electromagnetic energisation is used only to augment the spring force and hold the second locking element in a position in which it obstructs radial outward movement of the first locking element.
