Description

FIELD OF THE INVENTION

The invention relates to a high reliability lock with a key with a given beard and several levers installed in the lock box.

In addition, the invention relates to a key for a high-security lock with a die, a rod and a beard, on which a key code is placed in the form of ledges.

State of the art

There are several options for high reliability locks for installation, for example, in safes. A disadvantage of many known types of locks is the possibility of penetrating through the hole from the side of the castle into the internal cavity of the castle with a suitable tool for actuating the suvald. Therefore, it is necessary to make the lock holes as small as possible, which leads to the manufacture of keys that are also small in size. For already known locks, it is also necessary to have, along with the key, for directly locking the lock an additional key to activate the migration of the levers to a new type of locking.

Disclosure of invention

The objective of the present invention is the creation of a lock of increased reliability with the ability to make the holes of the lock as small as possible or the obvious simplification of the manipulations for reconfiguring the levers.

This task in the first embodiment of the invention is solved by the fact that a double-beard key is provided as the only means for activating and reconfiguring the levers and actuating the locking mechanism.

The lock according to the invention can be actuated with only one key. This key serves, on the one hand, to actuate the locking mechanism and, on the other hand, to reset the levers without using any additional tools, and the key simultaneously performs the task of initiating the reset. Since the key can be removed from the lock in the reset position, the lock can also be released in this position.

It is additionally provided that the hole provided for inserting the key into the lock has a diameter of 9.5 mm to 11 mm. So, for example, in the manufacture of safes, this size range gives the advantage of the need to provide only a small hole in the safe door. Only at the very late stage, due to the manufacturing features, it is necessary to determine which lock will be installed in the safe - the lock according to the invention, a combination lock or an electronic lock. This makes it possible to make a hole for inserting the key in the lock box and the corresponding hole in the safe door is also of a special small size, which significantly increases reliability, since a unlocking tool is also small and the manipulation with it is much more difficult. The size of 9.5 mm corresponds, according to statistics, to the minimum specified value, the size of 11 mm corresponds to the additional condition that, for security reasons, the size of such a hole should not exceed 100 mm ² .

A possible solution to such a lock with one single key for actuating the locking mechanism of the lock and reconfiguring the suvald involves the use of an asterisk as a structural element for reconfiguring the suvald and / or controlling the locking function.

Such an asterisk is a multifunctional structural element and many functions. The asterisk performs, along with the immediate locking function, with the corresponding key manipulation, also the function of reconfiguring the levers in several operations and, as a compact structural element, part of the functions that the key or beard of the key usually performs and that go beyond the usual locking when interacting with levers. Such a lock in combination with the corresponding key can provide the possibility of realizing the beginning of the reconfiguration of the key, for example, by turning it in the opposite hole direction.

It is envisaged that the sprocket has a latch fork designed to manipulate the deadbolt of the lock and / or a tuning cam intended for reconfiguring the level lever. By means of a plug, a directly locking function is realized, i.e. when you turn the sprocket with a key, the lock is unlocked and locked through the locking mechanism. The cam is a structural element for the reconfiguration of levers.

Being, according to the invention, the main structural element of the lock, the sprocket has, on its back, with respect to the direction of insertion of the key, parts, the latch fork and the permutation cam and is a single unit with the latch fork and the permutation cam.

It is directly provided that the fork of the heck is transverse to the radial direction of the sprocket. With the appropriate rotation of the sprocket with a key, the latch fork unlocks or locks the locking mechanism of the lock and moves the latch.

It is further provided that the permissive cam is located on the sprocket mainly in the radial direction, i.e. has the shape of an arc curve.

When the latch fork transfers the rotational moment from the action of the key to the latch via its longitudinal side, the permutation cam located in the radial direction on the sprocket shifts the individual structural elements to the corresponding position when the lock reconfiguration function is activated, which will be discussed in more detail below.

In another embodiment of the invention, it is provided that the permissive cam is located relative to the axis in front of the fork and / or relative to the radial direction of the sprocket behind the fork of the heck. This means, on the one hand, that the latch fork is located relative to the radial direction of the sprocket behind the permutation cam. On the other hand, this means that, relative to the axis, the permutation cap is located at a greater distance than the fork of the heck from the plane of the sprocket. This provides, on the one hand, a free and independent actuation when locking and reconfiguration of the levers, on the other hand.

In addition, it is provided that the asterisk provides the necessary alignment for the free entry of the key. This is mainly about one or more beveled chamfers integrated into the asterisk, which provide automatic key alignment. This solution may eliminate the need for alignment in the form of a drilled hole in the key rod and pin from the side of the lock box. This, in spite of the presence of the provided centering drilled hole, mainly does not lead to a decrease in the strength of the material with the risk of damage then in the form of cracks, dents, etc.

Concerning the rearrangement of the suvald, it is provided that, in order to initiate the function of reconfiguring the lock to the unlocking position, a longitudinally positioned shifting retainer having a spring on a side facing the box wall serves as a spring.

Turning the key does not directly affect the permutation latch. It is proposed to place a permutation eye activated by a permutation cam in front of the permutation latch. To do this, the key, if necessary, rearrange the suvald turn against the usual direction of opening the lock. In this case, an asterisk, or rather, a permutation cam, squeezes the rotary permutation eye from its position, thereby activating the permutation eye and the latch.

In this case, the permutation latch in the unlocked position provides the possibility of setting the locking eye in the working position, the implementation of which corresponds to the permutation latch. The locking eye goes into the permutation latch, which completes the process of initiating the reset.

In another advantageous embodiment of the invention, it is provided that a spring element is coupled to the levers, which enables the positioning of the individual levers. Instead of individual springs, a compact and easily mounted structural element is provided in the form of a leaf spring acting on all the levers simultaneously and holding them in a neutral position so that the key can be easily inserted into the lock.

In addition, for positioning the suvald, the installation of a guide made according to the levers is proposed. In a preferred embodiment of the invention, such a guide is a pin integrated in the lid of the lock box. When mounting the lock box, the pin takes up a place corresponding to the position of the leveling pad.

When making levers, they provide holes corresponding to the pin, serving the forced direction of the levers when they move around the pin.

The side jumpers provided in the keyhole as a protection in the direction of movement of the key perform a dual function, being at the same time an effective obstacle to the levers.

In another embodiment of the invention, it is provided that the levers in the keyhole area for the key have inserts for limiting the size of the lock well.

In addition, the object of the invention according to the second embodiment related to the key is solved in such a way that the key beard has protrusions on both sides, the diameter of the key beard measured between the maximum protruding edges of the protrusions is from 9.5 mm to 11 mm.

Thus, the key encoding is performed in the most compact way, in which it is located similarly to conventional keys with a double beard on the key beard. The maximum diameter of the key beard is from 9.5 mm to 11 mm, and the maximum diameter is understood as the distance between two or more maximally protruding edges of the protrusions of the beard located on both opposite sides of the key beard. At the same time, the hole provided for introducing the key in the lock box and in the corresponding door can be made as small as possible, which significantly increases reliability, since the unlocking tool must also be as small as possible, which makes it difficult to manipulate it. The size of 9.5 mm corresponds, according to statistics, to the minimum specified value, the size of 11 mm corresponds to the additional condition that, for security reasons, the size of such a hole should not exceed 100 mm. An advantage of the key according to the invention is also that the protrusions are located on both sides of the key beard, and thus the key is a double beard key. Due to its small size, the key can be easily inserted into the levers, since no space is required for the part of the key shaft between both halves of the beard. Thus, the key according to the invention can be used both for locking and for initiating a reconfiguration of the key.

In addition, it is provided that the key beard is made integrally with a part of the key shaft. In this case, it is, for example, a key with a coupling mechanism, i.e. about a key with a rod divided into two parts, one part being a beard and the other a key die. Both parts of the rod are connected to each other by a coupling mechanism. The fact that the key beard and the corresponding part of the key shaft are a single unit, provides to a large extent the necessary key strength with a relatively small size.

Another advantage of the compact double-bit key size is its low-cost production capability. It is possible, for example, to make a key beard and part of its shaft as a single structural element by powder injection molding. The manufacture of a relatively small beard and the corresponding part of the key shaft by powder injection molding can greatly reduce the manufacturing time or the number of work steps necessary for this. The invention is distinguished, in particular, in that a lock of increased reliability is created that meets the most stringent safety requirements and is particularly suitable for use in safe doors. The key used to lock the lock simultaneously performs the function of resetting the levers. Thanks to this, there is no need for a special hole on the front or rear wall of the lock box for the tool for reconfiguring levers. The lock can be released already in the reset position if the key can be removed from the lock in the reset position. In this case, the migration process can be completely completed only when using the appropriate key with the previously valid code. In this case, the asterisk performs part of the functions usually performed simultaneously by several structural elements of the castle. This primarily relates to the migration of the levers and to the initialization of the migration, as well as to the migration of the lock to a new type of locking. The asterisk in this case is to a certain extent a continuation of the key, imitating it as a drive for unlocking a lock or a latch and being the main structural element of the mechanism for reconfiguring levers. To do this, on the front side of the sprocket are locking and permutation cams. This turns the asterisk into a multifunctional structural element, eliminating, in particular, the need to use a special key for reconfiguration in the future. Reconfiguration is initiated in this case by turning the key against the usual direction of unlocking the lock.

Due to its compactness, the key according to the invention meets the highest safety requirements, being a double-bit key. This key has protrusions on both sides, and the ends of the protrusions as far as possible from each other are at a distance from 9 mm to 11.5 mm. Moreover, the key according to the invention meets, on the one hand, the requirements of strength and, on the other hand, has a particularly small size, which makes it possible to make a corresponding hole behind the lock, for example, in the wall of the safe is also correspondingly small in size and, thus, the ability to increase reliability .

The implementation of the invention

Figure 1 shows the part of the key with a double beard 7, including a segment 11 of the key shaft 10 and the next beard 12 with the end face 43 of the key shaft 10. Some of the protrusions of the key bar 12 are indicated by the numbers 13, 14, 18, 56, 57 and 58 . Moreover, on the side 59 of the beard 12, the protrusion of the beard 14 and the protrusion of the beard 13 on the opposite side 60 are maximally distant from each other. The distance between the protrusions 13 and 14, which are most distant from each other in this embodiment of the invention, is from 9.5 mm to 11 mm. In other words, the diameter of the key beard 12 relative to each pair of protrusions as distant from each other as possible, in this case the protrusions 13 and 14, lies in the range of the indicated sizes, which are advantageous in terms of strength and, on the other hand, safety. Additionally, this diameter is indicated by 42, 42 '.

Figure 2 shows the back side 6 of the sprocket 3 with both main structural elements - a fork of the latch 4 for activating the function of reconfiguring the lock and the permutation cam 5 for reconfiguring the levers. Moreover, on the axis side 45, the permutation cam 5 is removed from the plane of the sprocket 3 at a greater distance than the fork of the latch 4.

Figure 3 shows a view of the sprocket 3 from the direction of insertion of the key relative to the front side 22. On the front side 22 there is a link 23. The numbers 16 and 17 indicate the centering devices for the inserted key, which is not shown here.

Figures 4, 5 and 6 schematically depict the mechanisms in the activation phase of reconfiguring the lock to a new unlock code. An advantageous option is to use a single key to activate the migration and its implementation. This key is indicated by the number 7 and in FIG. 4 it is already in the turned position for the usual unlocking of the lock in the activation phase of the reset. In this case, the permutation cam 5 drives the permutation eye 20 on the sprocket 3 in the direction of the arrow 46. The permutation latch 8 is in the normal position, the output of the locking eye is blocked, the shoulder 47 of the permuting latch blocks the shoulder 48 of the locking eye 21.

Figure 5 shows the activation of the permutation eyelet 20 and then the permutation latch 8. The permutation latch 8 is displaced in the direction of the arrow 9. The spring 15 of the permutation latch 8 serves as a support for the structural element on the wall of the lock box. The locking eye 21 can go with his shoulder 48 into the locking recess 49 or into the permutation latch 8.

Figure 6 shows the triggered locking eye 21; the reconfiguration phase in this case is completed, and the key 7 can be turned back to the main position, which is not shown here.

Figures 7-10 show the phase of reconfiguring the lock to a new unlock code. 7, the key 7 is shown in the insertion position in the lock. A spring 32, depicted as a leaf spring 37, is located at the end of the box 2 of the lock 1, which is turned away from the latch 29 and is located. The spring 32, 37 holds the levers, which were rearranged with the key in the neutral position, and are closed by the levers 24, constantly in this position. The numbers 33 and 34 indicate two inserts that serve to reduce the size of the hole 35 for the key 7 and, thereby, to complicate the use of an unexpected manipulation tool.

In Fig.8 shows the key 7 after turning about 70 ° compared with the position in Fig.7. Heck 29 is in the locked position. The levers covered by the upper levers 24, lowered to the key 7 and sorted for the current locking. The number 27 denotes the hole in the leveling lever 24, which, in conjunction with the pin integrated in the box cover, serves to force the leveling lever 24.

In Fig.9 shows the lock 1 after turning the key about 135 °, the latch 29 is in the unlocked position, the implementation of the reset is not possible.

Figure 10 shows the activation of the reconfiguration by turning the key 7 against the unlocking direction by about 80 ° and again to its original position. After that, the key 7 is rotated further than with the usual unlocking of the lock until it stops (approximately 180 °) and can be removed from the lock. A new key with the appropriate encoding can be inserted into the lock, and lock 1 can be locked. The reconfiguration is thereby completed.

11 shows the lid 31 of the lock box 2. A pin 30 is integrated perpendicular to the cover 31 as a guide for the suvald not shown here. A key hole 30 is located next to the pin 30 and the key has two shutters 50, 51, which simultaneously serve as protection against manipulations, preventing penetration of the dumps not shown here.
