Description
KEY AND ASSOCIATED LOCK
The invention relates to a key for locking a lock with at
least one first surface and at least one second surface and
at least one sensing position provided along the
longitudinal extent, at which sensing position on the first
surface at least one first code is provided for reading in
the lock and/or at least one second code is provided on the
second surface for reading in the lock. The invention
furthermore relates to a lock for a key of this type.
Keys of this type with two encoded surfaces are known from
the prior art, specifically as reversible keys in
particular. Reversible keys are keys, the shaft of which
has uniformly arranged profiles, guide grooves,
depressions, elevations or/and notches on both sides. The
key therefore in each case has the same features rotated
about the longitudinal axis thereof and can therefore –
independently of the side of the key which is pointing
upwards – also be introduced into the keyway of the
associated lock cylinder in a rotated fashion, which is not
possible in the case of a normal key which has notches on
one side.
As the codes on reversible keys are identical on both
sides, for the most part in the lock, the codes are read on
each side alternately, in order to reduce the number of
sensing elements. In this context, the term "identical
codes" means that the codes are the same on the
respectively considered surfaces when the key is rotated
about the longitudinal axis thereof.
In reversible keys of this type, the depiction of one side
is sufficient however in order to be able to reproduce the
key. This is disadvantageous with regards to modern
reproduction methods (high-resolution smartphone cameras in
combination with 3D printing), as illegal keys can easily
be brought into circulation.
A further problem is that it would be advantageous in
practice for two locking systems, which in each case have
lock cylinders with reversible keys, to realize
superordinate keys which lock in both locking systems.
Furthermore, in the case of reversible keys with a lateral
groove code, the problem emerges that the individual curves
must be identical on both sides of the key. Limitations for
the realization of the grooves at the key tip result
however: The central position of the tumbler at the key tip
cannot be used, as there would otherwise be an increased
danger of breakage.
It is the object of the invention to overcome this and
further problems, particularly the problem of ease of
copying reversible keys. An option should furthermore be
created, in order to be able to lock a plurality of
different reversible key locking systems using the same
key. Furthermore, the described limitation for the lateral
groove code should be overcome. In addition, the variation
options on the key should be increased, and greater locking
security should be ensured. Identical effects should also
be achieved with regards to the new construction of the
lock.
This and further objects are achieved according to the
invention in that at least one code of the first surface of
the key differs at least at one sensing position from the
second code at the same sensing position on the second
surface, so that to lock the lock, at least the codes at
this sensing position must be read at this sensing position
on both surfaces.
This has the advantage that the codes are different on both
sides of the key and it is consequently substantially more
difficult for unauthorized persons to copy the key.
The solution according to the invention makes it possible
with one key to lock one or more lock cylinders of a
locking system and, if the key is rotated about the
longitudinal axis thereof through 90° to 180°, one or more
lock cylinders of a different locking system. In this case,
it may be provided that a key, which has the same code on
both sides, does not have locking authorization. It may
however also be provided that a key, which has the same
code on both sides, has locking authorization. One
advantage of the solution according to the invention is
that the feature for the authorization to lock a plurality
of locking cylinders does not have to be accommodated in
the locking cylinder of the locking systems, rather it is
realized with at least two or more features on different
surfaces of the key itself. As a result, a key can be
designed, which has a superordinate function in two
different reversible key locking systems, but does not have
the reversible key function itself. This may for example be
a superordinate key for authorized persons, such as fire
brigades, night watchmen, home helps or the like.
A further advantage of the solution according to the
invention, when designing the key with curve codes, is that
due to the different shape of the curves on the two sides
of the key, the central tumbler at the key tip can then
also be used, as it does not have to be milled on both
sides in the form of a groove.
It may be provided according to the invention that at least
one code of the first surface is identical at least at one
sensing position to the code at the same sensing position
on the second surface, so that to lock the lock, at least
the codes at this sensing position only have to be read on
one surface of the key at this sensing position. A
plurality of codes may also be present at a sensing
position, of which codes one or more is realized
identically on all surfaces of the key, and one or more is
realized differently on at least one surface of the key.
According to the invention, it may be provided that, in
addition to the codes mentioned, further codes may be
provided on the surfaces and/or at other locations on the
key. The codes mentioned and/or further codes may
essentially comprise rectilinear, angled or bent,
horizontally or vertically running grooves, channels,
milled sections, notches or elevations, control surfaces,
control paths, recesses, drilled recesses with identical or
different diameters and/or depths, mounted balls, circular
or elliptical segment recesses, spherical-segment-shaped
elevations or recesses, magnetic codes, electronic codes
and/or combinations of these elements.
The invention may provide that the surfaces are key flat
sides of a flat key. The invention may likewise provide
that the surfaces are key narrow sides of a flat key. The
invention may furthermore provide that the first surface is
a key narrow side and the second surface is a key flat
side. The second surface may enclose an arbitrary angle,
particularly approximately 90° or approximately 180°, with
the first surface of the key.
The invention may provide that the codes are formed by
control points provided transversely to the longitudinal
extent of the key and arranged at certain control heights,
wherein the control points are preferably connected to one
another by control grooves.
The invention may provide that at least one control groove
is provided with control points on the first surface and at
least one control groove is likewise provided with control
points on the second surface, wherein the control points of
each control groove are provided at a defined sensing
position in each case, and at least one control point of at
least one control groove has a different control height at
least at one sensing position on the first surface than the
control point of the corresponding control groove at the
same sensing position on the second surface.
The invention may provide that at least one control point
of at least one control groove has the same control height
at least at one sensing position on the first surface as
the control point of the corresponding control groove at
the same sensing position on the second surface. In
particular, the invention may provide that at least six
sensing positions A–F and at least six control heights a–f
are provided.
The invention may provide that at least three control
grooves are provided, of which at least one is constructed
as a deep control groove with deep control points, and the
remaining control grooves are constructed as shallow
control grooves with shallow control points, wherein the
deep control grooves have a larger groove depth than the
shallow control grooves, and the shallow control grooves
run essentially parallel to one another.
The invention may provide that at least three, preferably
five, control heights are provided for at least one of the
control grooves, preferably for the shallow control
grooves.
The invention may provide that the codes are initially
realized identically on both surfaces on at least one
sensing position starting from the key tip in the direction
of the key bow, and are continuously realized differently
from a certain sensing position. It may in particular be
provided that the deep control groove or the shallow
control grooves, starting from the key tip in the direction
towards the key bow only extend up to a certain sensing
position, so that up to this sensing position, at each
sensing position on each surface two shallow and one deep
control groove are provided, and from this sensing
position, at each sensing position only one shallow or two
deep control grooves are provided.
The invention furthermore extends to a lock for keys
according to the invention, comprising a keyway with at
least two sides, with sensing positions provided along the
longitudinal extent of the keyway, wherein at least one
control element for reading at least one code on at least
one surface of the key is provided at each sensing
position, wherein at least one locking element is provided,
which, given an appropriate position of the control
element, can be brought into a released position for
actuating the lock, and wherein control elements for
reading different codes on at least two surfaces of the key
are provided at least at one sensing position on at least
two sites of the keyway.
The invention may provide that control elements for reading
the same code, particularly for reading different features
of the same code, on at least two surfaces of the key are
provided at least at a further sensing position on at least
two sides of the keyway. It may in particular be provided
that the control elements comprise control organs for
engaging in codes, particularly for engaging in control
grooves on the key.
The invention may provide that the control elements
comprise first control organs for engaging in deep control
grooves and second control organs for engaging in shallow
control grooves. It may furthermore be provided that the
control elements for controlling the locking elements have
engaging means, particularly one or more reading grooves,
which interact with the locking element in one or more
positions of the control element in such a manner that the
same can be brought into a release position for actuating
the lock.
The invention may provide that the key is a flat key and/or
the lock is a cylinder lock, particularly a cylinder lock
for accommodating a flat key.
The invention furthermore extends to a system made up of at
least two locks according to the invention or groups of
locks according to the invention and at least one
associated key according to the invention, wherein at least
one first lock or a first lock group reads at least only
the first code on the first surface at least at one
specific sensing position, and at least one second lock or
a second lock group reads at least only the second code on
the second surface of the key at the same sensing position,
so that the key locks the first lock or the first lock
group in a first position and locks the second lock or the
second lock group in a second position.
Further features according to the invention emerge from the
description of the exemplary embodiments, the patent claims
and the drawings.
The invention is explained in more detail in the following
on the basis of non-limiting exemplary embodiments:

view;

Figs 14 - 15 show further schematic illustrations of
the tumblers in the interior of the
cylinder core of a lock according to the
invention;
Fig. 16 shows a schematic three-dimensional
illustration of the tumblers in the
interior of the cylinder core of a lock
according to the invention.
Figs 1a - 1d show cross sections through exemplary
embodiments of conventional keys and keys 1 according to
the invention at a specific sensing position, wherein in
each case a cross section through the key shaft of a
conventional reversible key is depicted on the left side
and a cross section through the key shaft of a key 1
according to the invention is depicted to the right
thereof. The keys 1 have a first surface 2 with first codes
3 and a second surface 2' with second codes 3' in each
case. While the codes 3, 3' of the conventional keys are
realized in such a manner that the keys match when the key
is rotated through 180°, this is not the case for the
exemplary embodiments of the key 1 according to the
invention.
Thus, it makes a difference whether the key is inserted
into the lock in the normal position or in a position
rotated through 180°. In the lock – at least at this
sensing position – both surfaces 2, 2' of the key 1 must be
read.
Figs 2a - 2c show cross sections through exemplary
embodiments of conventional key/lock combinations and
key/lock combinations according to the invention. Fig. 2a
shows a cross section through a conventional lock with a
core 23, which is rotatably mounted in a housing 24, into
which a conventional key 1 is inserted. Control elements
13, 13' are arranged in a displaceable manner on both sides
of the key 1, which control elements interact with locking
elements 14, 14' which engage in housing grooves. The key 1
is a key with a lateral groove code. The lock is realized
in the conventional manner and reads the two shallow
grooves on the side 2 using the control organs 18 and the
deep groove on the other side 2' using the control organ
17'. The position of the deep groove on surface 2 and the
shallow grooves on side 2' is not read, as it is assumed –
owing to the reversible key system – that the codes are the
same on both surfaces 2, 2'.
Fig. 2b shows a cross section through an exemplary
embodiment of a key/lock combination according to the
invention. In this case, the codes in the form of deep
grooves on the surfaces 2, 2' of the key are different and
are also read independently of one another on both sides of
the key. In order to be able to read both codes on each
surface 2, 2', the locking elements 13, 13' engage on both
sides into the deep groove via first control organs 17,
17'.
As the deep groove is at a different position, depending on
the rotation of the key 1, however, the control elements
13, 13' each have two reading grooves 19, 19' for engaging
the locking elements 14, 14'. The locking elements 14, 14'
are therefore activated in two different positions of the
control elements 13, 13' in each case and lock the lock.
Although the key 1 is not a reversible key – as the codes
on surface 2 and 2' are different – the key functions as a
reversible key, as both surfaces of the key are read in
both positions.
Fig. 2c shows an analogous embodiment to Fig. 2b with the
difference that at the illustrated sensing position of the
key 1, the code is not realized by one deep groove per
surface 2, 2' in each case, but rather by two shallow
grooves per surface 2, 2’ in each case. The control
elements 13, 13' each have two control organs 18, 18' for
engaging in the shallow grooves, and each have two reading
grooves 19, 19' for engaging the locking elements 14, 14'.
The locking elements 14, 14' are therefore activated, as in
the exemplary embodiment of Fig. 2b, in two different
positions of the control elements 13, 13' in each case and
lock the lock, although this is not a reversible key.
In an exemplary embodiment which is not illustrated, the
lock has a further mechanical reading logic, particularly
of the locking elements 14, 14', which logic ensures that
the lock from Fig. 2b or Fig. 2c cannot be locked by a
conventional reversible key with identical codes on the
surfaces 2, 2', but rather can be locked exclusively by
means of keys with different codes.
Figs 3a - 3b show an exemplary embodiment of a key 1
according to the invention, which is realized as a flat key
with a key bow 10 and a key tip 20 and two opposite
surfaces 2, 2'. The surfaces 2, 2' are the key flat sides
16, 16'. Sensing positions 4 are provided for both surfaces
2, 2' along the longitudinal extent of the key 1, namely
six sensing positions A – F. A code 3, 3' is located at
each sensing position 4 on both surfaces 2, 2' of the key
1, wherein the first code 3 is provided on the surface 2
and the second code 3' is provided on the surface 2'.
The codes are realized differently on the sensing position
A, and identically on the sensing positions B – F. A lock
which only senses one side of the key, can therefore only
be actuated in one position of the key. In order to be able
to read both codes at the sensing position A, the lock must
be realized in such a manner that it reads both surfaces 2,
2' of the key 1 independently of one another at least at
the sensing position A.
Figs 4a - 4b show a further exemplary embodiment of a key 1
according to the invention, which is realized as a flat key
with a key bow 10 and a key tip 20 and two opposite
surfaces 2, 2'. The surfaces 2, 2' are the key flat sides
16, 16'. Sensing positions 4 are provided for both surfaces
2, 2' along the longitudinal extent of the key 1, namely
six sensing positions A – F. A code 3, 3' is located at
each sensing position 4 on both surfaces 2, 2' of the key
1, wherein the first code 3 is provided on the surface 2
and the second code 3' is provided on the surface 2'.
The codes are realized differently on the sensing position
A, and identically on the sensing positions B – F. In this
exemplary embodiment, the codes 3, 3' are realized as
drilled recesses 21, 21' with a different depth and/or
diameter.
Figs 5a - 5b show a further exemplary embodiment of a key 1
according to the invention, which is realized as a flat key
with a key bow 10 and a key tip 20 and two opposite
surfaces 2, 2'. The surfaces 2, 2' are the key narrow sides
, 15’. Sensing positions 4 are provided for both surfaces
2, 2' along the longitudinal extent of the key 1, namely
six sensing positions A – F. A code 3, 3' is located at
each sensing position 4 on both surfaces 2, 2' of the key
1, wherein the first code 3 is provided on the surface 2
and the second code 3' is provided on the surface 2'. The
codes are realized differently on the sensing position A,
and identically on the sensing positions B – F. In this
exemplary embodiment, the codes 3, 3' are realized as
notches 22, 22' with a different depth and/or extent.
Figs 6a - 6b show the key from Figs 3a – 3b in a detail
view. The key 1 is realized as a flat key with a key tip 20
and two opposite surfaces 2, 2'. The surfaces 2, 2' are the
key flat sides 16, 16'. Sensing positions 4 are provided
for both surfaces 2, 2' along the longitudinal extent of
the key 1, namely six sensing positions A – F.
A code 3, 3' is located at each sensing position 4 on both
surfaces 2, 2’ of the key 1, wherein the first code 3 is
provided on the surface 2 and the second code 3' is
provided on the surface 2'. The codes are realized
differently on the sensing position A, and identically on
the sensing positions B – F.
The codes 3, 3' comprise deep control points 6, 6' and
shallow control points 7, 7' which are connected to one
another by means of a deep control groove 8, 8' and two
shallow control grooves 9, 9' in each case. The deep
control grooves 8, 8' have a larger groove depth than the
shallow control grooves 9, 9'. The shallow control grooves
9, 9’ run substantially parallel to one another.
The control points 6, 6', 7, 7' are arranged at the reading
positions at control heights 5 provided transversely to the
longitudinal extent of the key 1. Six control heights a – f
are provided in this exemplary embodiment. Whilst the
control points 6, 6', 7, 7' at the sensing positions B – F
are identical on both surfaces 2, 2' of the key 1, the deep
control point 6, 6' is arranged at a different control
height 5 on the two surfaces 2, 2' at the sensing position
Figs 7a - 9b show further exemplary embodiments of keys
according to the invention. In these exemplary embodiments,
starting from the key tip 20 to the key bow 10, the deep
control groove 8, 8' initially runs identically on a few
sensing positions on both surfaces 2, 2' of the key 1. From
a specific sensing position, the deep control groove 8, 8'
is realized differently on the surfaces 2, 2'. The shallow
control grooves 9, 9' extend, starting from the key tip 20,
only up to this specific sensing position.
As a result, this means that up to this sensing position,
it is only necessary to read on one side of the key, whilst
from this sensing position, both sides of the key must be
read (as shown in Fig. 2b).
Figs 10a – 12b show further exemplary embodiments of keys
according to the invention. In these exemplary embodiments,
starting from the key tip 20 to the key bow 10, the shallow
control grooves 9, 9' initially run identically on a few
sensing positions on both surfaces 2, 2' of the key 1.
From a specific sensing position, the shallow control
grooves 9, 9' are realized differently on the surfaces 2,
2'. The deep control groove 8, 8' extends, starting from
the key tip 20, only up to this specific sensing position.
As a result, this means that up to this sensing position,
it is only necessary to read on one side of the key, whilst
from this sensing position, both sides of the key must be
read (as shown in Fig. 2c).
Figs 13a - 13b show a schematic illustration of the
tumblers in the interior of the cylinder core of a lock
according to the invention, wherein the key and cylinder
core and housing have not been illustrated for reasons of
clarity. Fig. 13a shows a view into the keyway 11 and shows
the control elements 13, 13', which read the keyway using
control organs 17, 17', 18, 18'. The control elements 13,
13' have reading grooves 19, 19' on the sides, which
interact with locking elements 14, 14'. A plan view of the
keyway 11 is illustrated in Fig. 13b, and the sensing
positions 12 A – F are illustrated. Two control elements
13, 13' are located on both sides of the keyway 11 at each
sensing position, which control elements either have first
control organs 17, 17' for reading the deep grooves on the
key, or second control organs 18, 18' for reading the
shallow grooves. The control elements 13, 13' are
illustrated once more in a position rotated through 90° to
the right and left of the keyway 11. This exemplary
embodiment of the lock is realized for a key as illustrated
in Figs 3a – 3b, as the grooves extend over the entire
length of the key shaft.
A design of the lock for a key as illustrated in Figs 9a –
9b is illustrated in Fig. 14. The deep and shallow grooves
of the key are sensed alternately at the sensing positions
A, B and C. At the sensing positions D, E and F, only the
deep groove is additionally sensed on both sides.
A design of the lock for a key as illustrated in Figs 12a –
12b is illustrated in Fig. 15. The deep and shallow grooves
of the key are sensed alternately at the sensing positions
A, B and C. At the sensing positions D, E and F, only the
shallow grooves are additionally sensed on both sides.
Fig. 16 shows a schematic three-dimensional illustration of
the tumblers in the interior of the cylinder core of a lock
according to the invention, wherein the control elements 13
and 13' are illustrated on both sides of the keyway 11. The
first control organs 17' for sensing the deep groove, and
the second control organs 18 for sensing the shallow
grooves are illustrated in the extracted detail. The
control organs 17, 17', 18, 18' are substantially
cylindrical elevations.
The reading grooves 19, 19' can likewise be seen in the
form of indents with a substantially rectangular cross
section, which serve to interact with the locking element
14, 14', as has been illustrated in Figs 2a – 2c.
The invention is not limited to the illustrated exemplary
embodiments, but rather comprises all embodiments in the
