Definitions

  • the invention relates to a security lock for security containers with a lock bolt arranged to be longitudinally displaceably guided in a lock housing, in particular by a wrench, to which a locking mechanism is assigned, which has a plurality of tumbler plates arranged parallel to one another and connected to the housing in one piece by a common, orthogonal to the lock bolt Axis through the different stages of the beard key are pivotable (rotating tumbler), the tumbler plates on the common pivot axis facing away from each z.
  • a security lock for security containers with a lock bolt arranged to be longitudinally displaceably guided in a lock housing, in particular by a wrench, to which a locking mechanism is assigned, which has a plurality of tumbler plates arranged parallel to one another and connected to the housing in one piece by a common, orthogonal to the lock bolt Axis through the different stages of the beard key are pivotable (rotating tumbler), the tumbler plates on the common pivot axis facing away from each z.
  • the tour channels successive tumbler plates depending on the levels of the key bit are offset from each other and the tumbler plates have control curves for the levels of the beard of the beard key or the like, in which the levels of the beard of the beard key or the like engage, such that by turning the beard key or the like, all Tour channels can be brought into a congruent position for the purpose of entry of the tour pin, whereupon the lock bolt can be moved longitudinally through the beard steps of the beard key or the like.
  • the bolt In the case of security locks for safes or other security containers, the bolt is normally locked with a beard step of e.g. B. moves as a wrench.
  • the other beard levels of the beard key move the tumbler plates, which block the bolt in its locked position in the rest position or when actuated with a wrong key.
  • the key In order to move a bolt in the open position, the key must first be turned through an initial angle so that the beard steps of the beard key can move the tumbler plates in the open position.
  • the control curve of the bolt, in which the beard step of the beard key engages, which moves the bolt, is designed such that the bolt is not yet moved during the rotation of the key by an initial angle.
  • the tumbler plates are arranged in the lock according to their position and coding.
  • the lock bolt has a locking element referred to as a "touring pin”, which is connected in one piece to the lock bolt and opposite the front edges (locking edge) of the tumbler plates in the lock.
  • each tumbler plate has a slot-shaped recess in the front edge, which is referred to as a "tour channel” and which is so large that the tour pin can be inserted into the tour channel with little play.
  • the tour channel of each tumbler plate is positioned by the beard steps of the key belonging to the lock via a control curve on each tumbler plate so that the tour pin and the tour channel lie opposite one another. In this position the lock bolt can be brought into the open position with the tour pen. If the key is incorrect, the tour pin hits the locking edge of the relevant tumbler plate.
  • auxiliary tools are used to move the tumbler plates into the open position.
  • scanning an attempt is made to find the position of the tumbler plates in which the tour pin can be inserted into the respective tour channel of the respective tumbler plate that is being scanned, that is to say the tour pin and the tour channel lie opposite one another.
  • the invention has for its object to turn off the "scanning" in a security lock of the required type and thereby significantly increase the security of the lock.
  • a tumbler plate In the package of tumbler plates that form the locking mechanism, e.g. B. a tumbler plate, the front edge of which is somewhat closer to the tour pin than with the other tumbler plates.
  • This tumbler plate which is slightly closer to the tour pin, is defined as a "locking tumbler plate”.
  • a contact between the tour pin and one of the other tumbler plates is only possible if this blocking tumbler plate is in the open position.
  • This locking tumbler plate controls a locking mechanism such that the other tumbler plates are blocked just before the locking tumbler plate is in the open position. It is then no longer possible to scan the other tumbler plates using the tour pen.
  • the invention is applicable if it is ensured that the other tumbler plates can be used with the correct one (suitable) key can be swiveled into the open position before blocking. All tumbler plates except for the locking tumbler plate can be provided on the same end face facing away from the center of pivoting with deceptive catches which are of identical design and lie in the same angular pattern.
  • Claims 3 to 5 describe a way to block the tumbler plates.
  • an angle lever is provided, which is controlled by a projection of the locking tumbler plate, such that the angle lever with a locking nose shortly before the locking tumbler plate is pivoted into the open position, engages in a locking catch of the other tumbler plates and these locking tumbler plates against blocking pivoting or movement.
  • This screening can be similar to the illusion screening on the blocking edge of the Tumbler plates should be formed.
  • the locking grid should be located at a different location on the tumblers, such as possibly a deception grid. The advantage of this locking grid over the illusion grid is that it can be uniform and has no palpable differences, such as z. B. is possible through the tour channel in the deception grid in other constructions.
  • the angle lever is arranged between two stops. This means that the angle lever cannot be pushed sideways by unauthorized persons.
  • a blocking pin is arranged which can enter a side slot, the slot opening into a window through which the tour pin extends.
  • Claim 8 describes an embodiment in which the locking tumbler plate is provided with a lateral, outwardly opening slot which opens into the recess for the control curves of the tumbler plate.
  • a resilient area is created so that unauthorized persons cannot exert any deforming force on the angle lever via the locking tumbler plate. Rather, the tumbler plate springs back into its original position immediately.
  • Pin 13 assumes a stop function here so that the resilient area of the locking tumbler cannot be overloaded. In the event of greater use of force, the resilient area of the locking tumbler bends around pin 13. This manipulation has little effect in the front area of the locking tumbler.
  • a security lock according to the invention for security containers can be provided with any number of tumbler plates, preferably one, but possibly also several locking tumbler plates.
  • a locking mechanism consists only of a locking tumbler plate, which is arranged below, that is, on the lock bottom, and z. B. from more than five tumbler plates.
  • Locking tumbler plates and tumbler plates can be made of brass, while the lever and the lock housing as well as the lock bolt itself can be made of steel.
  • the reference numeral 1 denotes a lock bolt, which in all of the embodiments shown in the drawing is arranged longitudinally displaceably in a one-piece lock housing 2 made of steel.
  • the castle ceiling is not shown for reasons of simplification.
  • the lock bolt 1 is fixed by spaced housing Pins 3 and 4 guided.
  • the reference numerals 5 and 6 denote screw bushings which extend orthogonally to the lock housing base and are integrally connected thereto and with which the lock cover, not shown, is detachably connected by screws, also not shown.
  • the screw bushing 6 is arranged with its center on the longitudinal center axis 7 of the lock bolt 1 and serves as a bearing and pivot axis for a locking mechanism 8 consisting of a plurality of plane-parallel arranged tumbler plates and preferably a locking tumbler plate 8. For reasons of simplification, only one tumbler plate was shown in the drawing 9 and a locking tumbler plate 10 arranged above it.
  • the locking mechanism 8 usually consists of a locking tumbler plate 10 and several, for. B. seven tumbler plates 9, which are all arranged plane-parallel to each other and the screw bush 6 as use common swivel axis.
  • all tumbler plates 9 and the locking tumbler plate 10 each have a bore with which they are pushed over the screw bushing 7 with a slight play, that is to say they can easily be pivoted about the screw bushing 6.
  • the locking tumbler plate 10 can face a concrete lock at the bottom, ie the inside of the lock housing base, while the tumbler plates are arranged above.
  • the reference numeral 11 designates a locking angle enlarging lever as described in detail in the German utility model G 92 03 393.8 which goes back to the applicant and which is positively coupled to the lock bolt 1 and via a longitudinal slot 12 and an orthogonal projection from the housing base, in one piece with it connected pin 13 forms a backdrop guide. However, pin 13 still performs a stop function here.
  • the reference numeral 14 denotes a double bit of a beard key, not shown in detail.
  • the reference numerals 15 and 16 denote tour channels which open out on the end faces 18 and 19 opposite a tour pin 17. All tumbler plates and all locking tumbler plates 10 have such slit-shaped tour channels 15 and 16, which are all of the same size and with a suitable beard key through the beard steps of the double bit 14 in the z. B. from Fig. 3 apparent position to each other, in which the tour pin 17 is able to slide into the topped channels 15 and 16 by corresponding longitudinal displacement of the lock bolt 1 by means of the key.
  • the width of the tour pin 17 is slightly smaller than the width of each tour channel 15 or 16, so that the tour pin 17 can slide easily into the tour channels 15, 16 when the lock bolt 1 is moved axially by a suitable wrench 14.
  • the tour pin 17 is arranged orthogonally to the lock bolt 1 and connected to it in one piece.
  • the reference numeral 20 denotes recesses in the tumbler plates 9 and the locking tumbler plates 10, which have control curves for the different levels of the key bit 14.
  • a control projection 22 is connected on one side to the locking tumbler plate 10 on its end face 18, with which a pawl 23 designed here as an angle lever can be controlled, which pawl can be pivoted to a limited extent with an eye 24 on the screw bushing 5.
  • the pawl 23 has two arms 25 and 26, which are arranged at right angles to one another in the illustrated embodiment, but can also have a different shape.
  • the arms 25 and 26 are material here designed in one piece with the eye 24, the eye 24 having a bore, not shown in detail, with which the pawl 23 is pivotally mounted on the screw bushing 5.
  • the pivoting range of the arm 26 is limited by two stops 27 and 28 which extend parallel to one another and orthogonally to the lock bottom.
  • a locking lug 29 is integrally connected, which protrudes by about 90 degrees to the longitudinal center axis of the arm 25 in the direction of the locking mechanism 8 and is designed such that it can engage in a locking mechanism 30.
  • the locking mechanism 30 is arranged on all tumbler plates 9, specifically on the front side facing the arm 25, and is of the same size and shape in all tumbler plates 9.
  • the locking lug 29 extends over the entire height of the locking mechanism 8 consisting of the tumbler plates 9 and the locking tumbler plate 10. In this way it is possible for the locking lug 29 to be able to block all tumbler plates 9 together and simultaneously against a pivoting movement around the screw bushing 6.
  • the locking nose 29 can be conically tapered in the direction of the locking catch 30 in order to facilitate entry and thus a positive connection when blocking.
  • the reference numeral 31 designates a pin which is connected in one piece to the lock case 1 and projects orthogonally with its longitudinal axis therefrom and the length of which is dimensioned such that it corresponds at least to the thickness of the entire locking mechanism 8.
  • All tumbler plates 9 and the locking tumbler plate 10 have recesses 32 through which the tour pin 17 passes, which is also so long that it corresponds to at least the total thickness of the locking mechanism 8 from all tumbler plates 9 and at least one locking tumbler plate 10.
  • the pin 31 is arranged next to the tour pin 17, the tour pin 17 lying in the embodiment shown on the longitudinal center axis 7 of the lock bolt 1.
  • the radius that delimits the end face 18 of the locking tumbler plate 10 is somewhat larger than the radius that delimits the end face 19 of the tumbler plate 9. This has the following consequences: If a security lock according to the invention shown in the drawing is opened with a suitable key 14, the beard steps control the tumbler plates 9 via the control cams in such a position that the tour channels 15 lie congruently one above the other, that is to say the tour pin 17 can slide axially into the tour channels 15.
  • the locking lug 29 enters the locking catch 30 of the tumbler plates 9 in a form-fitting manner.
  • the locking mechanism 30 of the tumbler plates 9 is congruently pivoted one above the other in such a way that the locking nose 29 blocks all tumbler plates 9, ie the entire package from all tumbler plates 9, against further pivoting. This is done in that through the beard steps on the control projection 22 of the locking tumbler plate 10 the arm 26 of the pawl 23 is pivoted and thus the arm 25 is pivoted in the blocking position.
  • the design and arrangement has been made so that the locking tumbler plate 10 is not yet fully open in this pivoted position (Fig. 2). Only a further turning of the appropriate key 14 (FIG.
  • the end faces 19 of the tumbler plate 9 prevent the bolt 7 from being axially displaceable. Manipulation with intrusion tools is not possible because the tumbler plates 9 are blocked by the locking lug 29 of the pawl 23 and can no longer be pivoted.
  • the pawl 23 is loaded by a spring 34 against the locking direction.
  • the locking catch 30 can be designed uniformly and have no palpable differences (all teeth and all gaps are of the same size and of the same shape).
  • all the tumbler plates 9 and / or the blocking tumbler plate 10 can be attached to the end faces 18 and 19 opposite the tour pin 17, which can be of identical or different design.
  • the locking tumbler plate 10 is located below the other tumbler plates.
  • the locking tumbler plate 10 controls a pawl 23 which, as in the other embodiments, is loaded against the restoring force of a spring 34.
  • the locking tumbler plate 10 is provided on its upper left end face, as seen in the drawing plane, with a locking catch 30 into which the locking lug 29 of the pawl 23 can engage.
  • the shifting of the tumbler plates 9 is prevented by unauthorized manipulation, as described in connection with the above embodiment.
