Description

The technical field to which the invention belongs

The invention relates to a locking device comprising a locking cylinder, a key and a tamper protection device, wherein the locking cylinder contains a cylinder core installed in the housing, and a separating gap is made between the housing and the cylinder core according to the restrictive part of paragraph 1 of the claims. In addition, the invention relates to a key, in particular for use with a locking device according to the invention.

State of the art

Numerous keys and locking systems are known from the prior art, which are designed with increased protection against burglary. For example, from DE 699 04 408 T2 a key with a movable pin is known, as well as a protective rotary cylinder and a lock equipped with them.

According to the solution disclosed there, a key is to be provided for the security swivel cylinder, the copying of which is difficult due to the presence of a movable pusher, whereby the user obtains increased security of the lock.

Since criminals are constantly looking for new ways to open locking systems, it is necessary to constantly improve the keys and locking systems. Therefore, in particular, the anti-tamper devices should be constantly improved in terms of protection against drilling and/or against pulling out.

Disclosure of the essence of the invention

From the foregoing, it is an object of the present invention to provide an improved locking device that includes a locking cylinder, a key, and a tamper-proof device. Furthermore, it is an object of the invention to provide an improved key which is particularly suitable for use with said improved locking device.

This problem is solved by means of a locking device, a locking cylinder, a key and an anti-tamper device according to the combination of features disclosed in paragraph 1 of the claims. The key solution is the subject of claim 13.

The dependent claims contain at least preferred embodiments and improvements.

In accordance with this, a locking device is proposed, which includes a locking cylinder, a key and an anti-tampering device, while the locking cylinder contains a cylinder core installed in a housing, and a separating gap is made between the housing and the cylinder core.

Said separating gap is made in such a way or has such dimensions that the cylinder core can rotate in the housing during the opening process. In this case, a separating gap should not be understood as an excessively large gap, on the contrary, separating gaps are often also called interfaces.

According to the invention, the tamper protection device comprises at least one security pin, which is movably mounted in the security pin channel, said security pin channel comprising a housing section and a cylinder core section.

In the locking position of the locking device, the security pin is at least partially located in the body section in the channel of the security pin in such a way that the separating gap is blocked. To obtain the open position of the locking device, the protective pin under the action of the key inserted into the cylinder core and at least one magnetic element made on the body or in the body of the key can completely move into the cylinder core section in the channel of the protective pin and unlock the separating gap.

The locking position of the locking device may also be the closed position of the locking device.

The tamper protection device comprises at least one security pin, at least one security pin channel, and at least one magnetic element made on the key body.

The channel of the protective pin is preferably designed so that it is located at least partially in the core of the cylinder and at least partially in the housing. In accordance with this, the channel of the protective pin contains a section of the body and a section of the cylinder core. The housing section and the cylinder core section are oriented relative to each other in such a way that they form a single channel of the protective pin. The housing section and the cylinder core section are preferably coaxial with each other to form a protective pin channel. A separating gap is made between the housing section and the cylinder core section.

In the locking position of the locking device, the security pin is located at least partially on the housing section in the channel of the security pin. In addition, the safety pin in the blocking position is additionally provided on the cylinder core portion, so that the safety pin passes through the separating gap and blocks it. In the locked position, the safety pin is preferably located mostly in the region of the cylinder core. The section of the cylinder core in the channel of the protective pin is preferably large, i.e. longer than the section of the body in the channel of the protective pin.

The locking position of the locking device refers to the completely closed state of the locking device, i.e. to a locked state. The locking position is also to be understood as a position in which the key is not yet fully inserted into the key channel of the locking cylinder.

Due to the design of the locking device according to the invention, an effective tamper protection device is provided, which makes it possible to increase the reliability of the locking device.

The security pin has, for example, a circular cross section. In one preferred embodiment of the invention, the security pin is made of steel. In one particularly preferred embodiment of the invention, at least one security pin is made of hardened steel.

In this case, the security pin can essentially consist of two main parts. The first part is preferably that part of the security pin which, in the locking position of the locking device, is located on the body section. The other or second part of the safety pin in the blocking position of the locking device is essentially in the region of the cylinder core. This second part may have a larger cross section than the first part of the security pin. Preferably, the magnetic element of the security pin is provided on the second part of the security pin.

The security pin preferably has a shape which, together with the complementary shape of the channel of the security pin, allows positioning of the security pin.

Under the action of the magnetic element made on the body or in the body of the key, the protective pin can move. In particular, the security pin can move in the direction of the magnetic element or, in other words, be attracted to it. Preferably, the safety pin is fully retracted into the cylinder core, whereby the separating gap is no longer blocked and thus released.

The cylinder core portion is preferably closed in the direction of the key channel in the cylinder core. On the other hand, the cylinder core portion in the protective pin channel is open towards the housing portion, so that the protective pin is suitably movable. In this case, the channel of the security pin is preferably not accessible from the side of the key channel. Thus, direct external action on at least one security pin from the side of the key channel is impossible. This provides additional protection against tampering.

In addition, at least two security pins may preferably be provided. In this case, said at least two security pins preferably have the same magnetic polarity. Said at least two security pins may each contain one magnetic element.

In another embodiment of the invention, the security pins themselves can be made in the form of magnetic elements. Both security pins preferably comprise a single-pole magnet or are designed as a single-pole magnet.

In the locking position of the locking device, the use of at least two security pins with the same magnetic polarity is preferred, since both security pins repel each other. Thus, under the action of the magnetic repulsive force, the security pins in the locked position are held on the body section of the corresponding channel of the security pin. In this case, the repulsive magnetic force can be used as an additional force to hold the protective pins on the housing section in the channel of the protective pin.

Preferably, at least two security pins are in the form of a north pole magnet and/or comprise a north pole magnet.

When installing two guard pins, the first guard pin can be preloaded by means of a spring, with the preload acting in the direction of the body section in the guard pin channel. To do this, a spring can be installed in the area of the cylinder core in the channel of the protective pin. This spring may advantageously rest on a portion of the cylinder core covering a section of the cylinder core in the protective pin channel. In this case, the spring is preferably installed in the upper channel of the protective pin.

In another guard pin channel, preferably the lower guard pin channel, no spring is required because the downward orientation of this guard pin channel guides the corresponding guard pin down by gravity, and thus it slides towards the housing part in the guard pin channel .

A key, in particular a reversible key, which in particular cooperates with a locking cylinder comprising at least two security pins of the same magnetic polarity, comprises at least two magnetic elements which have the same magnetic polarity.

The magnetic elements of the key, in particular the reversible key, have a polarity preferably opposite to that of the security pins. The security pins preferably comprise a north pole magnet or are a north pole magnet. Each magnetic element of the key is preferably in the form of a south pole magnet.

When the reversible key is inserted into the locking cylinder, both security pins are retracted, since they have a first magnetic polarity, towards the magnetic elements, which have a second polarity. The two security pins are thus retracted in the direction of the key, in particular in the direction of the reversible key, whereby the separating gap is unlocked.

The magnetic elements of the key are preferably made in the form of single-pole magnets. In one particularly preferred embodiment of the invention, the magnetic elements of the key, in particular the reversible key, are in the form of south pole magnets.

At the end of the key body facing the key head, at least one magnetic element may be provided. In other words, the magnetic element may be provided at the end of the key body which points in the direction of the key head or key ring.

Thus, since the magnetic element is preferably provided near the key head or key ring, the security pin can only be moved after the key body has been substantially inserted into the key channel provided in the cylinder core.

In this case, it should be indicated that the security pin does not interact with the coding element of the key. In particular, said at least one security pin does not create additional coding for the locking device. The security pin serves solely to protect against unauthorized intervention, in particular to protect against drilling and/or pulling and/or knocking out and/or opening with a pick.

Also, in particular, it should be pointed out that said at least one security pin is not a coding element. Known keys contain mechanical and/or electronic coding in the form of cutouts and/or drilled grooves and/or electronic elements. The key profile also serves as an encoding element.

This coding is checked in the locking cylinder. If the profile and other coding elements of the key match the profile of the locking cylinder, the key can be inserted. In addition, with corresponding key cutouts, the coding pins in the locking cylinder are positioned so that the core of the locking cylinder can be rotated. In this case, in known locking devices, coding is carried out due to the fact that cutouts or drilled grooves are located at different depths and/or in different places of the key.

The locking device according to the invention may contain additional coding elements. However, the security pins described are not to be understood as part of such encoders.

In one embodiment of the invention, the cylinder core, as described above, is provided with a security pin that serves as an anti-pull feature. This pull-out protection element forms a form-fitting connection between the cylinder core and the body of the locking cylinder. A form-fitting connection cannot be overcome by means of a mechanical aid, since said at least one security pin is located in a security pin channel closed on the side of the key channel. Direct contact with the pull-out protection element (protective pin) is prevented. Since the pull-out protection element (protection pin) can also be designed to protect against drilling, additional possible interference becomes more difficult.

The key of such a locking device may be a cylinder key or an English key or a reversible key.

At least one magnetic element is preferably provided in a coding-free area of the key body, in particular free of holes and/or recesses. In other words, the magnetic element is made on a section of the key body where there is not a single hole and/or not a single notch.

The at least one magnetic element is preferably provided outside of the grooves or cutouts intended to encode the key. Such an arrangement of at least one magnetic element in a coding-free area ensures that there is no kinematically locked connection between the key body and the security pin, so that the key can move further in the axial direction.

On both wide sides of the key body, at least one magnetic element can be provided. In this case, it is preferable that at least two magnetic elements are installed at equal distances to the nose of the key and/or to the back of the key.

Alternatively, the at least two magnetic elements may be positioned at different distances to the nose of the key and/or to the back of the key.

In this case, both magnetic elements, for example, in the presence of only one security pin, can more effectively, i.e. with increased force, act on this safety pin.

If two security pins are provided, due to different distances from the magnetic elements to the nose of the key and/or to the back of the key, each magnetic element can have a different effect on the corresponding security pin.

In another embodiment of the invention, at least one magnetic element is provided on the back of the key. In one particularly preferred embodiment of the invention, at least one first magnetic element can be provided on the back of the key and at least one second magnetic element on the side of the key body opposite the back of the key. Due to this variable position of the at least one magnetic element, the security pin can also be mounted in the variably aligned channels of the security pin. If at least one magnetic element is provided on the back of the key, it is preferable to provide that the security pin runs perpendicular to the longitudinal direction of the key body.

At least one safety pin can be installed in the channel of the safety pin with preload. In particular, the security pin is preloaded in such a way that, in the locking position of the locking device, it is pushed towards the housing section in the channel of the security pin. In one particularly preferred embodiment of the invention, at least one security pin can be installed in the channel of the security pin, preloaded by a spring. Due to the applied preload force, the protection against tampering, in particular the protection against drilling and/or the protection against pulling out, is increased.

At least one security pin may be provided on the side of the locking cylinder facing the cylinder cover and/or the key channel opening. If at least one security pin is provided in the vicinity of the cylinder cover or the security rosette, or thus in the vicinity of the opening of the key channel, the security pin can only be actuated after the key body has been almost completely inserted into the key channel and then moved in the direction of the area cylinder core in the protective pin channel.

In one embodiment of the invention, the axis of the security pin channel may extend parallel to the longitudinal direction of the key channel opening. The axis of the channel of the security pin is to be understood as the longitudinal axis of the channel of the security pin. The longitudinal direction of the key channel opening is to be understood as the direction with the greatest extent of the cross section of the key channel opening. Thus, the axis of the security pin channel and the longitudinal direction of the key channel opening preferably run parallel to each other.

In addition, the axis of the security pin channel in this embodiment preferably extends perpendicular to the longitudinal axis of the key channel. The longitudinal axis of the key channel is to be understood as the axis of the key channel, which defines the direction of movement or the direction of insertion of the key body.

In another embodiment of the invention, the axis of the security pin channel can extend perpendicularly, in particular at right angles to the longitudinal direction of the key channel opening and perpendicular to the longitudinal axis of the key channel. Such an embodiment of the invention is preferred, in particular if at least one magnetic element is provided in the back or on the back of the key body.

The tamper protection device may be provided with two security pins, each of which is movably mounted in a respective channel of the security pin. The two channels of the security pins are preferably arranged parallel to each other. In a particularly preferred embodiment of the invention, both security pin channels are parallel to each other and substantially perpendicular to the longitudinal axis of the key channel.

In one possible embodiment of the invention, both security pin channels run parallel to each other and substantially mirror-symmetrical to the longitudinal direction of the key channel opening.

The term "essentially mirror-symmetrical" in this case should be understood such an arrangement of the channels of the protective pins, in which they have a minimum deviation from parallelism to each other and/or from the distance to the axis of symmetry. The presence of two security pins, made with the possibility of activation under the action of the magnetic elements of the key, in turn, increases protection against tampering.

Since the at least one security pin can only be actuated if the key body is almost completely inserted into the key channel, it can be ensured that the magnetic elements can only be actuated after numerous standardized decoding operations have been carried out.

The key of the locking device according to the invention comprises known coding elements, which first of all cause, for example, the movement of the pins of the body, so that the key body can be gradually inserted into the key channel, and when the key body is almost completely inserted, the security pin can be actuated, due to which ensures that the separating gap is unlocked.

Another, in particular, additional independent aspect of the invention relates to a key, which serves in particular for use with the locking device according to the invention.

The specified key is made, in particular, in the form of a reversible key, which contains two discrete magnets with the same polarity.

In a reversible key suitable for use in a locking device according to the invention, it is necessary to have two independent magnets so that they can interact with the magnetic polarity of at least two security pins.

Discrete magnets can be formed, for example, using a microcoil. In this case, a battery can be installed in the head of the key according to the invention in order to enable the activation of m and k coils.

In addition, discrete magnets can be formed using piezoelectric elements.

In one particularly preferred embodiment of the invention, the discrete magnets are in the form of single pole magnets. Particularly preferred are discrete south pole magnets.

In another embodiment of the invention, the key may consist of two halves. The dividing line between the halves of the key in this case runs from the head of the key to the spout of the key along the entire length in the longitudinal direction of the corresponding opening of the key channel.

Both halves of the key are respectively magnetized.

FIG. 5b: the embodiment of FIG. 5a with the key inserted.

In the following description, the same reference signs are used for the same and similarly functioning elements.

Implementation of the invention

FIG. 1a and 1b show a first embodiment of a locking device 10 according to the invention.

FIG. 1a shows the locking position of the locking device. In this case, the key is not inserted into the locking cylinder.

FIG. 1b shows the body 52 of the key 50. In this case, the body 52 of the key is inserted into the channel 32 for the key.

The locking device 10 includes a locking cylinder 20, a key 50 and an anti-tamper device. The locking cylinder 20, in turn, includes a cylinder core 30 mounted in the housing 40. Between the housing 40 and the cylinder core 30, a separating gap 25 is provided. The presence of the separating gap 25 allows the cylinder core 30 to be rotated in the housing.

In addition, the security pin 35 can be seen. The security pin 35 is movably mounted in the channel 41 of the security pin. The channel of the protective pin contains section 45 of the housing and section 46 of the core of the cylinder. In this case, the section 46 of the core of the cylinder in the channel 41 of the protective pin is made in the core 30 of the cylinder. The housing section 45 in the security pin channel 41, on the other hand, is located in the housing 40. The housing section 45 and the cylinder core section 46 are arranged coaxially with each other, thus forming the security pin channel 41. It can be seen that the section 45 of the body is significantly smaller than the section 46 of the cylinder core.

In the locked position shown, the guard pin 35 is also located in the housing portion 45, with the guard pin 35 extending from the cylinder core portion 46 through the separating gap 25 and protruding into the housing portion 45. The security pin 35 is provided in a portion of the locking cylinder 20 facing the cylinder cover 22 or the key channel opening 33 . Therefore, the security pin 35 can only be activated after the key body 52 has been largely inserted into the key channel 32 .

As shown in FIG. 1b, the key body 52 is inserted into the key channel 32. The protective pin 35 is acted upon by the magnetic force of the magnetic element 60. The protective pin 35 is shifted or attracted in the direction of the magnetic element 60. As a result, the protective pin 35 is located only in the cylinder core portion 46 in the channel 41 of the protective pin. In this way, the separating gap 25 is no longer blocked by the safety pin 35, so that the cylinder core 30 is released and can be rotated.

FIG. 2a and 2b show a second embodiment of a locking device 10 according to the invention, in which the locking device 10 closely resembles the embodiment shown in FIG. 1a and 1b.

The only difference is the spring 28 installed in the channel 41 of the protective pin, in particular in the area 46 of the cylinder core in the channel 41 of the protective pin. The spring 28 presses the security pin 35 towards the housing section 45 in the channel 41 of the security pin. Thus, in the lock position shown in FIG. 2a, the safety pin is pressed against the housing portion 45 by the force of the spring. This increases the effectiveness of protection against tampering.

On the other hand, in FIG. 2b shows that the key body 52 with the magnetic element 60 is inserted into the key channel 32. The protective pin 35 moves under the action of magnetic forces in the direction of the magnetic element 60. In this case, the spring 28 is compressed. The dimensions of the spring 28 and the security pin 35 are chosen so that both the compressed spring 28 and the security pin 35 can fit completely on the cylinder core section 46 in the channel 41 of the security pin during the open position of the locking device 10.

The separating gap 25 in the position shown in FIG. 2b is released so that the cylinder core 30 in the housing 40 can be rotated.

FIG. 3a shows the key 50 of the locking device 10 according to the invention. It can be seen that the magnetic element 60 is provided at the end of the key body 52 facing the key head 51 (not shown) or the neck 56 of the key. In other words, the magnetic element is provided at the end of the key body 52 opposite to the key nose 53 . The body 52 of the key on the wide sides 55 of the key contains cutouts 58. In addition, the coding elements 59 can be seen on the back 54 of the key.

As shown in longitudinal section in FIG. 3b, on the side 57 of the key body 52 opposite the key back 54, a magnetic element may well be provided. In this case, the magnetic elements are made at equal distances to the spout 53 of the key. In alternative embodiments of the invention, the magnetic elements can be provided on the wide sides 55 of the key and at varying distances to the nose 53 of the key and/or to the back 54 of the key.

FIG. 4a shows another embodiment of a locking device 10 according to the invention. In this case, the key 50 contains a magnetic element 60 on both wide sides 55, although in this case only one wide side 55 of the key can be seen.

The magnetic element 60, in turn, is made at the end of the body 52 of the key, opposite the spout 53 of the key. FIG. 4a, a partial section can be seen which shows that the locking cylinder 20 comprises a cylinder cover 22. In addition, you can see the security pin 35. It is installed in the channel 41 of the security pin, while in FIG. 4a, it can be seen that the security pin 35 is located in the housing section 45 in the channel 41 of the security pin. In this case, the separating gap 25 is blocked.

The axis A of the channel of the security pin is parallel to the longitudinal direction LE of the hole 33 of the key channel. On the side of the locking cylinder 20, shown without a section, another security pin is also provided with a corresponding security pin channel (not shown). In this case, the axis A of the channel 41 of the security pin runs perpendicular to the longitudinal axis L of the channel 32 for the key.

FIG. 5a shows another embodiment of a locking device 10 according to the invention. FIG. 5a, the key is not inserted in the key channel 32. Thus, in FIG. 5a shows the locking position of the locking device 10.

Two security pins 35 can be seen, each of which is provided in a respective channel 41 of the security pin. The channel 41 of the security pin, more specifically its section 46 of the cylinder core, is closed in the direction of the channel 32 for the key. This is provided by the cylinder core portion 36 located between the key channel 32 and the cylinder core portion 46 . Thus, the security pins 35 are inaccessible from the key channel 32 side.

Upper security pin 35, i. e. the security pin 35 above the key channel 32 is preloaded by the spring 28. The spring 28 presses the security pin 35 upwards towards the housing portion 45. For the bottom safety pin 35, i.e. made under the key channel 32, no such preloading is required because the safety pin 35 slides down by gravity towards the housing section 45.

It should be understood that each of the two security pins 35 comprises a first part 37 and a second part 38. The first parts 37 serve in particular to insert the corresponding security pin 35 into the housing section 45. In order to effect rotation of the cylinder core 30, the end sides 39 of the guard pins 35 are suitably chamfered.

The second parts 38 are somewhat wider. In this case, the shape of the second parts 38 of the protective pins 35 influences the positioning of the pin 35 in the channel 41 of the protective pin, in particular in the region 46 of the cylinder core.

In addition, respective magnets 34 are provided in the second parts 38. These magnets 34 have the same magnetic polarity, in particular north polarity. Thus, the magnets 34 and the security pins 35 in the locking position shown are further repelled from each other, so that the repulsive force further presses the security pins 35 into their positions in the housing portions 45.

FIG. 5a also shows that the axes of the channels 41 of the security pins run essentially parallel to each other. The axes of the channels 41 of the security pins are arranged perpendicular to the longitudinal axis of the key channel and also perpendicular to the longitudinal direction of the hole 33 of the key channel.

FIG. 5b shows the locking device 10 with the key 50 inserted, which in this case is a reversible key.

The key 50 contains two magnetic elements 60. The magnetic elements 60 have the same magnetic polarity. In this case, the magnetic polarity of the magnetic elements 60 of the key 50 is opposite to the magnetic polarity of the magnets 34 of the security pins 35. Accordingly, the security pins 35 or their magnets 34, when the key 50 is inserted into the key channel 32, move in the direction of the key 50. In this case, the magnetic attraction force overcomes the preload force of the spring 28 as well as the gravity force of the lower safety pin 35. For this reason, the separating gap 25 is released.
