Definitions

  • the invention relates to a locking device with a housing, a lock cylinder rotatably mounted in this housing, which is provided with a key channel, engages in the at least one locking member under the action of a radially acting locking spring, which by inserting the associated key against the action the locking spring moves from a locking position into an actuating position in which the locking cylinder can be moved into a closed position or into an open position and which, by pulling out the key, returns to a locked position.
  • Locking devices of this type are known, for example, under the name "platelet locking cylinder".
  • plates are radially displaceable and are held in the locked position by a spring.
  • a serrated key can be inserted into the key channel of the locking cylinder and through the locking plate. In the inserted state, it retracts the locking plate radially against the action of the locking springs so that the locking cylinder can be rotated 90 ° in the housing.
  • the key can be removed in the open position and also in the closed position.
  • the key is locked in the intermediate positions. This locking device can only be brought into the open position and into the closed position with the aid of a suitable key.
  • the present invention has for its object to provide a locking device of the type mentioned that it consists of only a few parts, is easy to assemble and only with the help of a key suitable for the locking device from the closed position to the open position and from the open position to the closed position can be brought.
  • lock cylinder is axially displaceable against the action of a return spring and the locking part releases the axial mobility of the lock cylinder when the key is inserted and locks when the key is removed and the lock cylinder by axially shifting and rotating, for example, 90 ° from an open position is movable into a closed position or vice versa and axially engages in both positions with a locking projection in locking recesses.
  • this locking position can only be actuated with the help of a suitable key.
  • the side walls of the locking channel and the side walls of the flat key are provided with longitudinal grooves and ribs, so that only a flat key can be inserted into the key channel, the ribs of which fit into the grooves of the key channel and vice versa.
  • the axial displacement of the locking cylinder is released, so that the locking cylinder can be moved from an open position into a closed position or from a closed position into an open position with a locking projection.
  • the locking device has an essentially cylindrical housing 1 in which a locking cylinder 2 is mounted, for example rotatable through an angle of 90 ° and axially displaceable against the action of a return spring 7.
  • the locking cylinder 2 is provided with a key channel 3 into which a key, in particular a flat key 6, can be inserted.
  • a radially displaceable locking part 4 engages in the key channel 3 and is under the action of a locking spring 5.
  • the locking spring 5 holds the locking part 4 in a locked position, so that the locking cylinder 2 cannot be moved axially. Since the lock cylinder 2 is locked axially into an open position 9 or into a closed position 11 via a locking projection 12, the lock cylinder cannot be rotated either.
  • the locking part 4 is radially displaced against the action of the locking spring 5, so that the locking cylinder 2 can be moved into a closed position or into an open position.
  • 1 shows the closing device in an open position. In this position, the locking pin 13 is retracted and, as shown in FIG. 6, the locking projection 12 is inserted into a locking recess 9 snaps, which is incorporated on the inner wall of the housing 1. If the key 6 has pressed the locking part 4 into the position shown in FIG. 4, the locking cylinder 2 can be pressed with its locking projection 12 against the action of the return spring 7 out of the locking recess 9 and rotated by 90 ° and thereby axially displaced until the locking projection 12 reaches the locking recess 10.
  • the locking pin 13 of the locking cylinder 2 has thus reached the closed position.
  • the locking recess 9 of the open position is connected to the locking recess 10 of the closed position via a curve 11. This ensures that the lock cylinder is axially displaced by turning the key and the lock cylinder 2.
  • the locking cylinder 2 is reduced in diameter in its part 28 facing away from the outside 27 and this reduced part 28 is guided in the bore 29 of a base plate 14 inserted into the housing 1.
  • the locking part 4 In the locked position, the locking part 4 with its locking edges 15 and 16 over the diameter of the bore 29.
  • the return spring 7 is arranged between the base plate 14 and the larger diameter part of the locking cylinder 2, whereby it encompasses the reduced diameter part 23.
  • the locking part 4 releases the axial mobility of the locking cylinder as soon as the key 6 is inserted and the locking edges 15 and 16 of the locking part 4 are retracted so far into the chamber 17 that these edges 15 and 16 can pass through the bore 29 in the base plate 14 .
  • the locking edge 15 shown in FIG. 3 blocks the axial mobility of the locking cylinder 2. If the key 6 is pulled out in the locking device according to FIG. 4, the locking projection 12 which engages in the locking recess 10 prevents the return spring 7 from locking the locking cylinder 2 pushes back and the locking edge 16 prevents the locking cylinder 2 with the locking projection 12 can be pressed out of the locking recess 10.
  • the switching gate 8 shown in FIGS. 6 and 7 is arranged with a latching recess 9 for the open position and a latching recess 10 axially and radially offset for the closed position of the latching projection 12 of the locking cylinder 2.
  • the Locking projection 12 integrally connected to the lock cylinder 2.
  • the locking projection 12 can also be formed by the locking part 4.
  • the locking part 4 is a U-shaped angled sheet metal part, the side walls 22 and 23 of which have a locking edge 15 for the open position and a locking position 16 for the closed position of the free edges Lock cylinder 2 forms.
  • the locking part 4 is inserted into a chamber 17 which is designed as an extension of the key channel 3 and is open on one side in such a way that the inner sides of its side walls 22, 23 are flush with the side walls of the key channel 3.
  • the locking spring 5 is designed as a tongue-like leaf spring connected in one piece to the locking part 4, the free end of which rests on the rear wall 26 of the chamber 17.
  • a ring 21 is pushed onto the reduced diameter part 28 of the locking cylinder, which forms a radial stop for the locking part 4 on the chamber 17 open on one side.
  • This ring 31 has the effect that when the key 6 is pulled out, the locking part 4 is reliably tilted by the locking spring 5 in such a way that the locking edges 15 or 16 reliably reach the locking position.
  • the key 6 is provided with a shaft stop 21 which interacts with a step which a recess 20 is formed. So that only very specific keys fit to the locking cylinders 2, grooves and ribs of different widths and depths are arranged on the side surfaces of the key channel 3 and the key 6, so that each longitudinal guide of the key channel 3 thus formed is assigned certain key profiles.
  • the locking cylinder 2 can also be provided with a pivotable bolt.
  • the locking device according to the invention is particularly suitable for locking window handles.
  • the housing 1 with the link guide 8 can be formed by a corresponding recess in the window handle.
  • the locking device is also suitable, for example, for control cabinets, mailboxes, suitcases and wherever a simple, reliable working locking device that works only with key operation is desired.
