- Fig. 1 shows part of a lock together with a key 70 inserted therein.
- the lock comprises a cap 10, a plug 20, a blocking bar 30, and validating elements 40.
- the lock further comprises a cap 10, a plug 20, a blocking bar 30, and validating elements 40.
- the cap 10 comprises a housing 50 (see Fig. 2), which has a circular cylindrical opening for receiving the components 20, 30, 40.
- the cap 10 may be arranged fully or partly outside of the housing 50.
- the components 10, 20, 30, 40 can be rotated relative to the housing 50 around the rotation axis 11a, whereby a driver (not shown) unlocks or locks the actual locking mechanism (not shown), e.g. a bolt of a door or the like.
- the plug 20 is configured to receive the key 70 and to carry the blocking and validating components 30, 40.
- the plug 20 comprises a keyway 21, which extends in the insertion direction of the key 70 and which serves for receiving the shank 71 of the key 70.
- the plug 20 has a receiving groove 22, which extends alongside of the plug 20 and which serves for receiving the blocking bar 30 in the unlocked state of the lock.
- the blocking bar 30 is preloaded, such that in the locked state it is pushed into a longitudinal groove 52 formed in the housing 50 opposed to the receiving groove 22. Thereby, rotation of the components 10, 20, 30, 40 with respect to the housing 50 is disabled (see groove 52 in Fig. 2 and 3) .
- the pushing force is e.g. produced by elastic means, e.g. in the form of one or more springs 34 (see Fig. 5) .
- the longitudinal groove 52 extends along a longitudinal
- the plug 20 has slits 23, each being arranged tranversally to the rotation axis 11a and serving for receiving an end portion of a validating element 40, so that the latter can cooperate with the blocking bar 30.
- the validating elements 40 are disc-shaped and rotatably arranged on an axle 11 (see Fig. 2), which is at one end attached to the cap 10 and axially fixed in a hole of the plug 20.
- a side portion 47 of a validating element 40 is configured to contact a support face 25 formed on the plug 20 such that the validating element 40 can be rotated only within a predetermined angle range (see Fig. 2) .
- the validating element 40 comprises a first arm 41, which is configured to contact a coding part of the key 70, and a second arm 42, which is configured to cooperate with the blocking bar 30.
- the validating element 40 includes a protrusion 43, which cooperates with an elastic mean, e.g. a spring such as a coil spring (not shown) .
- the plug 20 includes blind holes 24, which are arranged transversally to the axle 11 and radially offset thereto (see Fig. 2) . Said elastic mean is arranged in a blind hole 24 and acts via the protrusion 43 on the validating element 40 so that the latter is pushed in a specific direction, which, in the example according to Fig. 2, is in the clockwise direction.
- validating element 40 senses the inner side of a key
- validating element 40 has a recess 44, which serves for receiving a ridge portion 31 of the blocking bar 30 (see Fig. 3 and 4) .
- the recess 44 is arranged with respect to the rotation axis 11a such that its shape is mirror symmetrical around an axis 44c which goes through the middle of the recess 44 and the rotation axis 11a.
- the second arm 42 may have one or more
- additional recesses 45, 46 which are "false” recesses having no mechanical function, but making it more difficult for someone who tries to pick the lock by finding the correct position of the validating element 40.
- a recess 45, 46 is provided on each side of the recess 44.
- the false recesses 45, 46 are formed such that a ridge portion 31 can be only partially received therein.
- the depth of the recesses 45, 46 is smaller than the depth of the recess 44 and therefore the blocking bar 30 cannot be fully received in the groove 22 to allow free rotation of the components 10, 20, 30, 40 together with the key 70 to be rotated with respect to the housing 50, and thus the sloping flank 36a or 36b of the blocking bar 30 (see Fig. 5) collides with a side of the longitudinal groove 52.
- the key 70 has a handling part, e.g. a bow, to which the key shank 71 is attached.
- the key shank 71 has a semi-closed profile enclosing at least partially the coding part.
- the key shank 70 has side
- a side portion 73, 74 encloses a coding cavity 73a, 74a, in which the key coding is formed, e.g. in form of one or more coding tracks.
- a coding track extends along the key shank 71 and may have e.g. a wavelike course.
- the coding track may be formed e.g. by a line of successive channel portions and/or ridge portions.
- the side portions 73, 74 prevent that the coding part of the key 70 is visible from outside. This impedes an unauthorized duplication of the key 70 e.g. by producing a copy based on pictures taken from the key 70.
- Fig. 5-7 show an embodiment of the blocking bar 30 in more detail.
- the blocking bar 30 comprises ridge portions 31 and spacer portions 32 arranged therebetween.
- the blocking bar 30 In the locked state of the lock the blocking bar 30 is pushed into the longitudinal groove 52 of the housing 50 by means of the elastics means 34, which are arranged between the plug 20 and the blocking bar 30.
- the latter 30 may have at least one recess 33 for receiving one end of a spring as elastics means 34. The other end may be received in a recess formed in the plug 20.
- Fig. 5 and 6 show two such recesses 33, each being formed in a spacer portion 32.
- the lock includes guiding means configured to guide the blocking bar 30 in its movement.
- the blocking bar 30 includes e.g. pegs 35, which are configured to be received in recesses formed in the plug 20.
- Fig. 5 and 6 show two such pegs 35, each being arranged on a spacer portion 32.
- the lateral side 36 of the blocking bar 30 which is
- each ridge portion 31 of the blocking bar 30 is arranged relative to a reference axis, e.g. the middle axis 30a, along which the blocking bar 30 extends, at a specific position.
- the number of ridge portions 31 and the number of possible positions with respect to the reference axis may be chosen differently, and may be two, three or more. Accordingly, the number of validating elements 40 may be one, two, three or more.
- another blocking bar which is configured to define a lock coding and which comprises e.g. ridge portions 31 at predetermined positions.
- the lock may be configured such that the second blocking bar is arranged opposite to the first blocking bar 30.
- the lock is provided with supplemental elements, which correspond to receiving groove 22, slits 23, blind holes 24 including the elastic means, support face 25, validating elements 40 and groove 52 and which may be arranged e.g. mirror
- Fig. 2 shows e.g. a longitudinal groove 52' which is arranged mirror symmetrically to the median plane and which may serve for receiving the second blocking bar in the locked state.
- the same elements as the validating elements 40 may be used, but arranged on the axle 11 in a mirror
- the validating elements are configured to sense the inner side of the other side portion of the key 70, which in the embodiment of Fig. 2 is the left side portion 73.
- the number of possible coding positions can be increased.
- the recess 44 in the validating element 40 is configured such that a ridge portion 31 can be received therein irrespective of the position of the ridge portion 31 relative to the reference axis 30a. This allows the usage of the same form for all validating elements 40.
- the shape of the recess 44 may e.g. not be completely complementary to the shape of the ridge portion 31. In the present
- each ridge portion 31 of the blocking bar 30 has a rectangular cross-section and the recess 44 has an
- the ridge portion 31 visible therein is arranged at the upmost position with respective to the middle axis 30a of the blocking bar 30.
- the upper part of the ridge portion 31 is slightly spaced away from the wall 44b, whereas the lower part of the ridge portion 31 is adjacent to the wall 44a.
- the validating element 40 has to be rotated a bit in the anticlockwise direction with respect to the position shown in Fig. 3. If the ridge portion 31 is arranged at the middle position with respect to the
- the ridge portion 31 is arranged at the lowermost position with respect to the reference axis 30a, the upper part of the ridge portion 31 is adjacent to the wall 44b, whereas the lower part of the ridge portion 31 is arranged slightly spaced away from the wall 44a
- the first arm 41 of a validating element 40 protrudes into a coding cavity 73a or 74b and follows the coding track of the key 70, whereby it is rotated accordingly around the axle 11.
- a validating element 40 and with it the recess 44 have a specific angular position. If the key 50 does not have the correct coding, then the lock remains in the locked state since at least one recess 44 of the validating elements 40 has not the correct
- the receiving groove 22 in the plug 20 is configured to receive the spacer portions 32 of the blocking bar 30.
- the recesses 44 correctly positioned form together with said receiving groove 22 a receiving space which is substantially complementary to the form defined by the portions 31, 32 of the blocking bar 30.
- the lock is locked again by rotating the key 70 and with it the components 10, 20, 30, 40 into the other direction, so that the blocking bar 30 can slide back into the groove 52.
- Withdrawal of the key 70 causes the validating elements 40 by means of the elastic means in the blind holes 24 to be returned back to the initial position, in which at least one of the recesses 44 is not in the correct positions anymore.
- the embodiment described so far has the advantage that the lock may be configured such that the lock coding is defined uniquely by one or more blocking bars.
- the lock coding is defined uniquely by one or more blocking bars.
