Definitions
- the invention relates to a combination lock with number wheels, where a key secret of the combination lock is adjustable and that with number wheel-side engagement elements are provided, clutch discs, which are on the clutch disc side Engagement elements and the number wheel side Engagement elements are in engagement with the number wheels, and a bolt, which is set with key secret the combination lock can be brought into its release position.
- Such combination locks are used in many ways, e.g. for closing containers such as luggage, furniture The like, but also for windows, doors, flaps etc.
- a disadvantage of these known combination locks is, on the one hand, that mechanical components must be provided by means of which the engagement between clutch discs and Number wheels against the force of towards this engagement acting spring devices can be canceled.
- it occurs in known combination locks of this type by inhibiting this for lifting the procedure provided components comparatively often to unwanted Recoding the key secret. If the Number wheels are then adjusted before unintentionally Newly encoded key secrets must be elaborate Measures are taken to get the combination lock back to be able to use as intended.
- the invention has for its object the above to further develop the generic combination lock in such a way that on the one hand unwanted re-coding is made considerably more difficult are and that on the other hand the number of components of the combination lock can be reduced.
- the clutch disc-side engaging elements on the one hand and / or the number wheel-side engaging elements on the other hand are designed so that the engagement between the number wheel and Clutch disc against the one acting in the direction of this engagement Preload can be canceled, provided that a number on the dial exerted tangential force acting in the circumferential direction thereof that exceeds a predefinable limit force.
- the clutch disc-side engaging elements as rounded or bevelled protrusions and the number wheel side Engagement elements as essentially cylindrical recesses are formed, in which the clutch disc side protruding rounded or bevelled protrusions, when the clutch disc and gear are engaged, is depending on the degree of rounding or chamfering on the clutch disc side Protrusions a resulting Limit force can be specified from which by exerting a tangential force the rounded or beveled on the number wheel Slide the projections out of the recesses on the number wheel side can. The greater the chamfer or rounding off the projections on the clutch disc side, the less the limit force from which the projections slide out the recesses on the number wheel side are made can.
- the number wheel side cylindrical recesses are rounded, by the extent of the rounding or bevels the recesses are ultimately no longer cylindrical have to.
- the application of the tangential force to the number wheel can be relieved if the number wheels on their outer ring Have engagement recesses into which a tip of a Tools, e.g. a ballpoint pen or the like, insertable is to remove the interference between the number wheel and clutch disc required tangential force on the Number wheel to transfer.
- a Tools e.g. a ballpoint pen or the like
- Embodiment of a combination lock according to the invention 1 can be used to securely close a wide variety of containers and devices, e.g. to close Luggage, furniture, doors, windows or the like.
- the combination lock 1 includes a housing 2, number wheels 3, Clutch discs 4, a locking member 5 and a base plate 6th
- the housing 2 and the base plate 6 form a receiving space for the other components of the combination lock 1.
- Combination lock 1 has three number wheels 3, whose Spaced axes of rotation and parallel to each other in the through the housing 2 and the base plate 6 formed receiving space are arranged. Basically, it is possible to use any Number of number wheels 3 to be provided, these also arranged rotatable about a common axis of rotation could be.
- Pivots 7 there are three in the housing 2 Pivots 7 are provided, on each of which a number wheel 3 is rotatably arranged.
- Each number wheel 3 protrudes through an im Housing 2 formed opening 8 from the housing 2 before, so that on the one hand the number wheel 3 can be actuated or rotated and on the other hand, the respective position of the number wheel 3 optically can be perceived.
- Each number wheel 3 has one in the illustrated embodiment corrugated outer ring 9 to the actuation or rotation to facilitate the respective number wheel 3.
- the outer wreath 9 has mutually equally spaced engagement recesses 10 into which a tip of a tool, e.g. one Ballpoint pen or the like, is insertable.
- each number wheel 3 On its facing the respective clutch disc 4 The end face is each number wheel 3 with in the circumferential direction equally spaced engagement wheel-side engagement elements 11 Mistake.
- These engaging elements 11 on the number wheel side are as can be seen in particular from FIG. 3, as rounded, provided with an essentially cylindrical basic shape Recesses 11 formed.
- Each clutch disc 4 is assigned to a number wheel 3 and sits with this number wheel 3 coaxial to this on the respective Pivot 7.
- Each clutch disc 4 has an edge recess 12. Only if the three edge recesses in the illustrated embodiment 12 of the three clutch disks 4 in that shown in Figure 1 Positioned in such a way, why on the three number wheels 3 of the combination lock 1 set its key secret must be, the locking member 5, which by means of a the spring device not shown in the direction its release position is applied from its locked position be brought into its release position since only then a shift of the locking member 5 in the left in Figure 1 Direction is possible. Otherwise there will be a shift of the locking member 5 blocked by locking projections 13th of the locking member 5 against the outer circumferential surfaces 14 of the clutch discs 4 concerns. Only when set on the number wheels 3 The locking projections 13 can be a key secret of the locking member 5 in the edge recesses 12 of the clutch discs 4 penetrate, whereby the locking member 5 in his Release position device.
- each clutch disc On its front side facing the respective number wheel 3 each clutch disc has 4 clutch disc-side engagement elements 15, which, as can be seen in particular from FIG. 3, formed as rounded or bevelled projections 15 are.
- each clutch disc 4 is loaded in their axial direction, so that each clutch disc 4 with its bevelled or rounded projections 15 in the number wheel side rounded Recesses 11 protrudes.
- the number of the projections 15 on the clutch disc side can correspond to the number of recesses 11 on the number wheel side, however, there may also be fewer projections on the clutch disc side 5 can be provided as recesses 11 on the number wheel side.
- the arrangement of the clutch disc-side projections 15 and the number wheel-side recesses 11 is selected so that all projections 15 on the clutch disc at the same time with the number wheel-side recesses 11 in engagement could be.
- the spring preload of the clutch discs 4 ensures that in normal operation of the combination lock Engagement between the number wheel-side recesses and the projections 15 on the clutch disc side are maintained becomes.
