Definitions

  • the invention relates to an electromagnetically controlled lock with a locking bolt having locking contours, with a locking device which has locking contours which are in the locked position of the locking bolt with its locking contours and come out of engagement when the electromagnet is energized, and with a locking bolt actuation.
  • Locks of the aforementioned type are installed, for example, in steel cabinets of security levels A and B (cf. VDMA standard sheet 24 992 from January 1990). There they are part of a convertible electromagnetic code lock.
  • the minimum requirements for such locks include the following (loc. Cit. 1 and 2 clause 4.1): The lock bolt must be blocked in the locked position. If a convertible electromagnetic code lock is used - a multi-lock lock, a combination lock or a convertible mechanical code lock is also permissible - only one with a six-digit setting code and real 1 million setting options with indirect locking is permitted - manual bolt actuation -. It must not be possible to open the lock via the battery contacts, due to a power failure, by applying voltage to the lock components or due to vibrations in the steel cabinet.
  • the locking device consists of a pivot arm arranged parallel to the lock bolt, which on the one hand has a groove for receiving an angle connected to the lock bolt, and on the other hand has a recess with which the pivot arm engages in an opening of a pivotable anchor plate of the electromagnet. If the lock is closed mechanically, a finger presses against the anchor plate and this against the electromagnet. In this position - the armature plate lies on the electromagnet - the swivel movement for the arm is released, the locked position between the arm and the angle is released, the lock bolt is locked under the action of a spring.
  • the lock can also be actuated electrically by energizing the electromagnet.
  • the excitation of the electromangent also causes the armature plate to pivot in contact with the electromagnet, thus releasing the pivot arm and triggering the closing movement described. De-energization of the electromagnet brings the lock back to its original position.
  • the well-known lock can thus be operated both mechanically and electrically.
  • the electrical actuation is not influenced by the mechanical actuation and vice versa, apart from the fact that the mechanical or electrical actuation is sufficient for the locking of the lock; To exclude the lock, both the electromagnet must be de-energized and the mechanical actuation must be in the starting position.
  • the known lock does not meet the above requirements for installation in steel cabinets of security levels A and B.
  • the invention has for its object to provide a lock with the features mentioned above so that at least the above requirements for installation in steel cabinets of security levels A and B are met.
  • this object is achieved in that the lock bolt has the locking contours on its inner end face, that at least two locking elements movable against it by a holding force in the direction of the electromagnet and attractable by it are provided in the locking device, each with at least one of the locking contours is provided, and that the electromagnet excited after entering a code successively disengages the locking contour with the lock bolt actuation.
  • the electromagnet is expedient in the region of the central axis of the lock bolt and mirror-symmetrical to the central axis, the two are each provided with a locking contour which is formed in the lock bolt in the opposite way to the locking contour, equipped with an anchor plate and movable against the action of a spring in the direction of the electromagnet Locking elements arranged.
  • an electromagnet and four crosswise arranged anchor plates can be provided, whose path of movement forms an angle of ⁇ 45 ° with the central axis.
  • the lock bolt is extended like a fork on its inner end face and has the locking contours on the inside of the fork.
  • Anchoring plates arranged at the same angle on a circle can also be arranged in the end view.
  • the lock bolt then consists of a three-dimensional fork or a hollow cylinder.
  • a plurality of electromagnets can also be provided, which are arranged either one behind the other or next to one another in the direction of movement of the lock bolt.
  • Each electromagnet includes two locking elements, in the locking contours of which locking contours of the lock bolt engage, which in turn is extended like a fork.
  • the electromagnets can be excited simultaneously or successively depending on partial codes or different codes.
  • the movement of the anchor plates does not have to be straight, but rather can take place on a circular path.
  • the formation of the lock is construction and security related.
  • the housing dimensions can be easily selected like that of a combination lock; Interchangeability is therefore given.
  • the lock can be used for right and left door hinges. Otherwise, the above-mentioned minimum requirements for a lock for installation in steel cabinets of security levels A and B are met.
  • the electromagnet has a guide, via which it can be moved in succession in the direction of the locking elements when the lock bolt is actuated.
  • the distance of the electromagnet from the blocking elements is successively reduced to a minimum. If the electromagnet is excited, it takes along the blocking element located in its vicinity, which can be equipped with one of the armature plates or can itself be made of ferromagnetic material. Since the air gap between the electromagnet and the blocking element is small in this process, the electrical energy required is low.
  • the electronic lock chosen as an exemplary embodiment has a housing 1 which is closed by a cover 2.
  • a lock bolt 3 emerges from the housing 1 on its end face, and an emergency lock slide 4 on the opposite end end.
  • the bottom of the housing 1 is penetrated by four fastening screws 5 provided at the corners for fastening, for example, in the door of a steel cabinet.
  • the floor is also penetrated by a drive shaft 6, via which the bolt is actuated manually.
  • a cam disk 7 is connected to the drive axle 6.
  • An upper control cam 8 is formed in the cam disk 7 on its upper side.
  • a wedge ring-shaped stop 10 protrudes above the upper side.
  • the cam plate is in the area of the fastening screws 5 7 recessed.
  • a lower control cam 9 is embedded in the underside of the cam disk 7.
  • a cam disk collar 11 is formed on the underside of the cam disk 7. With the aid of the cam disc collar 11, the cam disc 7 is guided in a housing guide flange 12 formed onto the bottom of the housing 1.
  • the cam disc collar 11 is provided with two parallel surfaces 13. On each of the parallel surfaces 13 is one of two coil springs 14 which are attached to the bottom of the housing 1 and penetrate the housing guide flange 12. The parallel surfaces 13 and the spiral spring 14 cause a locking of the cam collar 11 at 0 ° and 180 °.
  • the guide pin 15 is fastened to a stop plate 16.
  • the stop plate 16 is arranged below the cover 2. It surrounds the area of the housing guide flange 12 in a U-shape.
  • the stop plate 16 is fastened on the lock bolt 3: on the front side of the housing 1, from which the lock bolt 3 emerges, it has two incisions 17 parallel to this end side. In each of the incisions 17 a projection 18 is formed on the lock bolt 3. Two locking contours 19 are also provided on the lock bolt 3 facing away from the end face.
  • Rotation of the drive axle 6 is transmitted to the cam disk 7 via a keyway 21 provided in the cam disk collar 11.
  • the guide pin 15 moves on a quarter of the upper control cam 8, which is designed as a semicircle ring in this area. If the locking contours 19 are released from their contact with opposite locking contours on a locking device at the end of the quarter circle in a manner yet to be described, the lock bolt 3 is released closed. After the quarter turn, the guide pin 15 travels along a practically linear part of the upper control cam 8 running close to the housing guide flange 12 and closes the lock bolt 3.
  • the upper control cam 8 - like the stop 10 - is arranged mirror-symmetrically to the longitudinal central axis 22 of the lock bolt 3.
  • the lower control curve 9 is also mirror-symmetrical, but with respect to a perpendicular 24 to the longitudinal central axis 22.
  • the view of the lower control curve 9 is mushroom-shaped.
  • a guide pin 25 surrounded by a sleeve engages in the lower control curve 9.
  • the guide pin 25 is fastened to a guide piece 26.
  • the guide piece 26 is U-shaped in the view and surrounds the housing guide flange 11. It is guided along a guide 27 provided in the perpendicular 24 to the longitudinal central axis 22 on the bottom of the housing 1.
  • a magnet 30 is attached to the guide piece 26.
  • the magnet 30 consists of a magnetic core 31 and a magnetic coil 32.
  • the magnetic coil 32 is connected via strands 33 to electronics, not shown.
  • the magnet 30 can be moved together with the guide piece 26 parallel to the guide 27 along a further perpendicular 34 to the longitudinal central axis 22 of the lock bolt 3.
  • the locking device 23 is provided in the form of two locking elements 35 on both sides of the magnet 30.
  • Each locking element 35 is formed by a profile piece that is movable relative to and with the magnet 30.
  • Each locking element 35 has a receptacle for an anchor plate 36.
  • Each locking element 35 also has a locking contour 37 opposite the locking contour 19 on the lock bolt 3.
  • the magnet 30 and the locking elements 35 are penetrated by a guide pin 38 which is arranged perpendicular to the longitudinal central axis 22.
  • a spring 39 By means of a spring 39, the locking elements 35 are kept pressed outwards - away from each other.
  • the spring 39 is arranged around the guide pin 38.
  • the solenoid 32 is energized. In its initial position shown in FIGS. 1 and 2, the magnet 30 bears against the lower locking element 35. If the magnet coil 32 is excited, the magnet 30 holds the lower anchor plate 36 and with it the associated locking element 35. If the drive shaft 6 is now rotated when the magnet coil 32 is excited, the guide pin 25 slides in the lower control cam 9, namely in one half of the foot of the mushroom-shaped part. The magnet 30 is thereby moved towards the upper locking element 35. If the air gap between the magnet 30 and the upper anchor plate 36 is small enough, the latter is attracted; the associated upper locking element 35 is also connected to the magnet 30.
  • the electronic lock still has the emergency lock slide 4.
  • the emergency lock slide 4 On the side of the locking elements 35 facing the lock bolt 3, the emergency lock slide 4 is provided with contours 40 which are arranged mirror-symmetrically to the longitudinal central axis 22 and are directed towards the locking elements 35.
  • Associated oppositely identical contours 41 have each of the locking elements 35 in the region of its side adjacent to the wall of the housing 1. If the emergency lock slide 4 can be pulled out of the housing 1, for example by actuating an associated key, the locking elements 35 are guided in the direction of the longitudinal central axis 22 via the contours 40 and 41 coming into contact. This also disables the locking contours 19 and 37; the lock bolt 3 can be excluded.
  • the lock can be used wherever rooms, cupboards or the like. be locked, especially for safes and steel cabinets.
