Description

Lock, in particular lock for box strong.

The invention relates to a lock, in particular to a lock for safe, with the characteristics  listed in the preamble of claim 1.

The lobster locks of the class before cited are well known for the state of the art as well by example by document DE 252 852 which refers to a lock safety with a special closing element.

Locks with plate skewers feature usually what is called a turning channel, which leaves free the opening path for the pivot pin arranged in the lock latch. Only when the channel is open turn the turn pin formed in the latch, that is, only when the turning channel is open you have the possibility of moving the lock latch and therefore open the lock.

The plate skewers present each one in its extreme area facing the pivot pin a recess open at one end, which in the open position of the lock are congruent next to each other forming this Turn channel mode. The unique positioning of the skewers of plates to form the turning channel are achieved by opening the lock using the lock key corresponding to the lock. To the perform a key opening rotation movement corresponding to the lock are the plate gachetas, which are supported with turning movement around an axis of rotation common, to its respective opening position that is characterized because each of the plate skewers is oriented in direction towards the turning pin with its recess made in the end zone on the side of the pivot pin. Only in this open position of the lock are the different skewers of plates arranged next to each other in such a way that the recesses of the plate gachetas form a common turning channel into which the pivot pin arranged in the lock latch, to open the lock.

He is also known for the state of the art that the lock latch is not directly actuated by means of the key pad corresponding to the lock but which serves as a latch actuator. He latch drive element acts in conjunction with the lock latch and moves it with a translation movement according to the direction of rotation of the key of the lock, to its position Locking or opening position. For this the joint action of the actuator element of the latch and the latch is realized in such a way that when the lock is opened, it only operates the latch when the plate skewers have been oriented in the opening position, that is to say that the recesses made in The plate pins leave the turning channel free for the pin turning arranged in the latch. Conversely, when it comes to placing the lock in its closed position the latch moves of the lock by actuating the latch first to its locked position, that is to say by actuation from the latch the latch is moved so that the pin of turn formed in the latch leaves the turn channel formed by the recesses of the plate gachetas. As for the pin of turn has left the turn channel you can turn the skewers of plates to their locked position, that is to their position of repose.

Although the lobster locks of the class described above have been accredited in everyday practice There is still a need for improvement. So for example it especially desires to reduce the manufacturing costs of a lock of this class through a simplified design but while increasing security against handling.

Starting from this, the objective of the invention is to improve a specific lock in the sense that together with the increased safety against tampering present a simplified structure and therefore more economical

To solve this objective, it is proposed with the invention a lock that has the characteristics according to the claim 1.

The actuator of the latch of the lock according to the invention has a locking element which ensures that the latch drive element is positioned in a safe position when the lock is in the closed position. This ensures that the element of latch drive cannot turn involuntarily. He latch drive element lock in position Lock closure presents essentially two advantages. By one part ensures that the drive element of the latch is always in the rest position in the lock position, which ensures that the key of the lock can be introduced in the element of latch drive, to operate the lock. If not there was the blocking element, the actuating element of the latch could for example spin involuntarily because of shaking, so it would not be possible to enter the key to actuate the lock. This inconvenience is overcome by safe position of the drive element of the latch in the locked position by means of the blocking element arranged in the actuation element of the latch. Another advantage of the solution according to the invention is that by blocking the drive element of the latch in the locked position of the lock are also left The plate skewers are positioned in their resting position, immobilized in a safe position. This prevents rotation involuntary of the plate gachetas, which increases the safety against tampering with the lock according to the invention.

The blocking element is made in shape of an elastic stirrup spring. The blocking element performed as a stirrup spring surrounds the neck housing of the key, the so-called key rod, made in the element of latch drive, so that the spring is opened stirrup when the key is inserted into the keyhole and therefore in the key housing provided in the element of latch drive. The opening or separation of the spring stirrup due to the introduction of the key results in the Locking element made as stirrup spring free the latch drive element, which makes it possible the turning movement of the latch drive element. Yes the key is removed in the locked position of the lock, that is it is removed from the housing for the key provided in the element of latch drive, the locking element made as stirrup spring returns to its original position thanks to its elastic embodiment, where the drive element is positioned of the latch in a safe position, that is to say it interlocks with with respect to the lock housing, so that a involuntary rotation movement of the drive element of the latch. The latch drive element is only can turn therefore when the key of the lock is introduced in the lock and therefore in the housing for the key formed in the latch drive element since only then does the blocking element release the element from latch drive.

In this regard and in accordance with a special feature of the invention, it may be provided that the  Locking element carry an encoding. With this realization special security is further increased against manipulation, because thanks to its coding, the element of blocking only releases the latch drive element, when the appropriate lock key is used for coding  of the blocking element. The lock according to the invention therefore offers two levels of security, since the key not only do you have to submit a coding of the pallet according to the assortment of plate skewers but also has to be made according to the coding of the blocking element, otherwise, the latch drive element It cannot be turned out of its interlocking position.

According to the invention, the element of lock made as stirrup spring presents on the sides ends some interlocking extensions that in the position closed the lock fit in some housings of interlocking made in the lock housing. These interlocking extensions made in the stirrup spring they block the turning movement of the drive element of the latch, and they do so while they fit into the housings of interlocking made in the lock housing. To the insert the key of the lock in the key housing carried out on the latch drive element the stirrup spring in the manner described above, which results in the interlocking extensions arranged in the spring of stirrup move out of the interlocking housings made in the lock housing. In this position of the interlocking extensions ie when they no longer fit in the interlocking housings, the interlocking the latch drive element which allows to make the turning movement of the drive element of the latch using the lock key inserted in the latch drive element.

According to another preferred feature of the invention the locking element has a centering in which can fit the end of the lock key on the side of the centering In the event that the blocking element is made as a stirrup spring, this centering is preferably formed by the part of the stirrup spring that joins the two arms together of the stirrup spring, whereby a design of a simple set. For centering purposes the end of the key the lock has a groove on the front side in which fits the stirrup spring part after inserting the key of the lock in the actuation element of the latch. This center ensures that after having the key of the lock is inserted in the drive element from the latch the stirrup spring is centered, and at the same time that the key of the lock introduced in the element of latch drive is oriented in exact position, it is say that even during a turning movement of the key of the lock the lock key pallet coding is always oriented in the correct position in relation to the coding formed by plate skewers. In a way simple but effective, a centering is obtained, the element state of actuation of the latch centered on the housing of the lock between the housing body and the lid, being centered the key of the lock in the drive element of the latch and the stirrup spring being centered by means of the key of the lock.

According to another preferred feature of the invention the latch drive element presents also a stop for the plate skewers. This cap is made preferably as a spike and serves to carry the plate skewers to the starting position when a closing process. In the closed position of the lock the Plate skewers are held securely in position by means of this stop disposed in the drive element of the latch, since after removing the key from the lock the latch drive element is securely fixed in its position by means of the blocking element. In this way effectively prevents a turning movement from occurring involuntary of the plate gachetas.

The proposed design is especially simple because by the state of the art so far only it was known how to keep plate skewers in their origin position by an independent spring system. This additional spring arrangement provided in accordance with the state of the technique can be omitted completely in the design according to the invention since the safe positioning of plate skewers  in the starting position is performed by the drive element of the latch, that is the stop provided therein, the latch drive element safely positioned in the closed position of the lock thanks to the locking element arranged there.

According to another preferred feature of the invention, the latch drive element has a lock washer This lock washer has a hole in slot shape to insert the key of the lock in the key housing provided in the drive element of the latch, and after turning the drive element of the latch results in the keyhole made in the housing of the lock is covered by the inside of the lock. Therefore, after turning the key it is impossible to see the inside of the lock through the keyhole, so that from the outside you can't see how they are arranged the plate skewers in their relative position with each other. Thanks to this measure also increases security against lock manipulation.

The latch drive element It also has a guiding device. This device of guided acts in conjunction with a guided edge made correspondingly with her and arranged in the latch of the lock. For this, the guiding device and the guiding edge are adjusted together so that a movement of translation of the latch caused by the drive element of the latch only begins when due to the turning movement of the key of the lock the skewers of selected plates are oriented correctly in their relative position with each other. With with respect to a lock opening this means that the latch can only be set in motion by the element  latch actuation when plate skewers are positioned in such a way that the recesses made in the Skewers of plates leave free the turning channel for the spike of shaped turn on the latch. Regarding a process of closure, the lock latch first comes out of the lock housing by means of the drive element of the latch, and it does a distance such that the spike formed in the latch leave the turning channel formed by the recesses of the plate skewers. Only when the spike turn the latch has left the turn channel, a new turn additional key also causes a turn of the skewers of plates, whereby the plate skewers are dragged into the form described above by means of the stop provided in the element of latch actuation, and are brought to their resting position characteristic of the closed position of the lock, in which placed in a fixed position thanks to the blocking element arranged in The latch element.

According to another preferred feature of the invention, the stop, the housing, the lock washer and the guiding device of the latch drive element They are made as a common set of one piece. This whole takes care of the support and complete guidance of the key of the lock and is located tamper proof inside the lock housing. This common set can be of plastic for reasons of simplifying construction and mainly for reasons of saving material, being carried out for example as a simple cast iron part. Since everything the support and guidance of the key is done by the aforementioned set, no centering of the lock key is required with respect to the lock housing as usual until now. By this reason, the key of the lock does not require the hole of centering that until now was mandatory, was already necessary in the locks known to the state of the art to house a key centering pin arranged at the bottom of the housing of the lock. Since the design of the lock conforms to the invention allows to give up a centering hole in the key, the key is less complex to manufacture and at the same time It improves its stability.

The lock is characterized by its new latch actuation element having an element of lock used to position the drive element of the latch in the closed position of the lock in the fixed position. This prevents a turning movement from occurring. involuntary of the latch drive element. He blocking element only releases a turning movement of the latch actuator when the key of the lock has been introduced in the lock and therefore in the key housing made in the drive element of the latch. The blocking element can be realized in a way encoded so that the locking of the actuator element of the latch can only be released using the appropriate key to the lock. By such an embodiment, purely optional, achieves a hitherto unknown combination of the beginning of a Skewer plate lock with the principle of a lock of cylinder. The principle of the cylinder lock provides that Only when entering the key are the elements of lock coded in the open position while in the The principle of the lock of skewers only happens to the opening position of the blocking elements, that is to say the plate skewers, when the key of the lock is turned. By optionally provided coding of the element of lock that puts the drive element in a safe position of the latch in the closed position of the lock is achieved Combine the two principles. The lock can therefore be performed in two stages tamper-proof, since with the Introduction of the lock key in the lock only it is possible to release the actuator from the latch if the key carries the coding corresponding to the blocking element. But after unlocking the latch element it is still not possible to open the key. This requires coding. adequate pallet, because only in case of coding suitable of the pallet you can take the plate skewers to your position that leaves the turning channel open. In this configuration optional latch drive element with its element The lock therefore assumes two kinds of functions. On one side the blocking element places the actuating element of the latch fixedly in the closed position of the lock, it is only possible to unlock the drive element of the latch if the key of the lock carries the coding corresponding to the blocking element.

Fig. 12 a detailed view according to detail XII of Fig. 11.

Figs. 1 and 2 show the lock 1 according to a preferred embodiment of the invention, each in an exploded representation, where Fig. 1 shows the lock in a view from the front and Fig. 2 shows the 1 lock in a view from behind.

In the lock 1 shown in Figs. 1 and 2 It is a safe lock, which features a latch 4 and several skewers of plates 5 arranged supported with movement of rotation around a common axis of rotation. The latch 4 and the Plate skewers 5 are housed in a housing that consists of a housing body 2 and a cover 3.

The common axis of rotation for the plate skewers 5 is formed by a bolt 6 formed in the body of the housing 2 as can be deduced especially from Fig. 1. For the arrangement of the plate skewers 5 in a rotating manner these they each have a housing hole 7 by means of which the plate skewers 5 are placed on the pin 6 which forms the common axis of rotation. This relationship can be deduced especially from the
Fig. 1.

To rotate plate skewers 5 to the closing position or opening position serves a key the lock 16, which is composed of a key neck 17 and a key pad 18 formed therein. The key to the lock can be inserted inside lock 1 with the paddle of key 18 ahead through a keyhole 15 made in cover 3. On the inside of the lock, the key neck 17 is housed in a drive element of latch 8. This actuator element of latch 8 is it consists of a set 24, made for example of plastic and a blocking element made as stirrup spring 22, whose Functions will be explained in more detail later.

The assembly 24 is preferably made of one piece as an injected cast iron and consists of a lock washer 13, a housing 12, a guiding device 14 and a spike 11.

The housing 12 is made as a cap closed on one side, and has two slots 25 facing each other and running in the longitudinal direction of the housing 12. The housing 12 in the form of a socket serves to house the key neck 17 of a lock key 16 introduced in lock 1, so that the inside diameter of the socket-shaped housing 12 essentially corresponds with the outer diameter of the neck 17 of the key 16. After insert the key 16 in the lock 1, the key pad 18 which carries the coding of the key 16 penetrates the slots 25 open on one side of the housing in the form of socket 12, and of this mode can come into contact with the encoding 36 facilitated by plate skewers 5.

The housing 12 is held by the side of the casing body rotatably through a guide hole made in the housing body 2, so that in state mounted the lock 1 the latch drive element 8 is rotatably supported around the longitudinal axis of the housing 12 in the guide hole 9. The guide hole 9 it may be surrounded by a raised flange, which has some stop edges 33 and 34 for the key protruding from the slots 25.

The assembly 24 of the drive element of the latch 8 also has a guiding device 14 that acts together with the guide edges 35 made in the latch 4. The guiding device 14 acting in conjunction with the guiding edges 35 of the lock latch 4 takes care that during a turning movement of a key 16 introduced in the housing 12 of the actuator element of the latch 8, the latch comes out or is picked up according to the direction of rotation of the key 16. Pickup of latch 4 is only possible when plate skewers 5 are in the open position as outlined below.

Each of the plate skewers 5 presents in its extreme area opposite bolt 6 which serves as a pivot axis a recess 20 open on one side. As you can see especially by Fig. 1, each of these recesses 20 is made as a torn hole. In the open position of the lock, the different plate skewers 5 are positioned one on another rotated respectively with respect to each other  such that their respective recesses 20 are congruent and they form what is called a turning channel, which leaves the path free opening for a pivot pin 21 arranged in the latch of the lock 4. In the open position of the plate skewers 5 the openings 20 open on one side, of the skewers of plates 5 are oriented in the direction of the pivot pin formed in the latch of the lock 4. In this position of the plate gachettes 5 the opening path for the turn pin 21 to housings 20 of plate gachettes 5, so that due to the actuation of latch 4 by means of the actuator element of the latch 8, can be moved to the left with respect to the drawing plane according to Fig. 2, that is, lock 1 can be opened. If only one of the Plate skewers 5 shown in Figs. 1 and 2 are not in the opening position, then no turning channel is formed open for the turn pin 21, so the latch is not can shift to the left, relative to the plane of the drawing according to Fig. 2. That is, if only one of the skewers of plates 5 is not properly aligned to form the channel of turn, that is not classified, lock 1 is in locked position because latch 4 cannot be moved to the opening position because the pivot pin trips plate skewers 5.

The assembly 24 of the drive element of the latch 8 also has the aforementioned pin 11 which is located in the guiding device 14 of the drive element of latch 8 and which serves as a drag for the lobsters of 5 plates rotatably supported. The purpose of spike 11 is to drag during a closing movement of the key 16 the Skewers of plates 5 rotatably supported, and take them to your starting position to be taken in the closed position of the lock. In this starting position the plate skewers 5 seat against pin 11, the drive element being of latch 8 immobilized in this position, by what the plate skewers 5 are safely retained by the pin 11, that is to say that there is no possibility of a involuntary turning movement of the plate skewers 5. To lock the actuator element of latch 8 in position The lock element 1 is used to close the lock 1 as stirrup spring 22, the arrangement and operation of which will describe later.

The body of the housing 2 carries inside a seat edge 10. This seat edge 10 serves to seat plate 5 skewers at tab level 39 in the bolt 6.

The extreme stops of a closing process are made by means of stop edges 33 and 34 making stops With the key pad.

Stirrup spring 22 serving as an element lock is part of the latch drive element 8, the stirrup spring 22 being supported by the housing 12 of the latch drive element 8. The stirrup spring 22 is formed by two spring arms, which are joined between yes at one end by an elastic part of the stirrup serving as centering 37 to center the stirrup spring 22 by means of the key 16. The stirrup spring 22 has on the side opposite to centering 27 two interlocking extensions 23 that in the closed position of the lock 1 fit in interlocking housings 26 made by the inner face of the cover 3. These interlocking housings 26 are made as notches formed on a bridge 29 as you can see especially by Fig. 2.

In the mounted state of lock 1 the spring of stirrup 22 is placed in the housing 12 of the element of latch drive. Housing 12 has grooves 37 through which the spring arms can pass stirrup 22, which are separated elastically due to widening of stirrup spring 22. In the closed position of lock 1 interlocking extensions 23 of stirrup spring 22 penetrate the interlocking housings 26 formed in the bridge 29. In this position the turning movement of the latch actuator 8. When key 16 is inserted in lock 1, that is in housing 12 provided by the latch drive element 8, widens or opens the stirrup spring 22 by the neck of the key 17 inserted in the housing 12, so that interlocking extensions 23 are driven out of the interlocking housings 26, what which allows a rotational movement of the latch actuator 8. The locked position of the latch drive element 8 is represented in the Fig. 3 to 7, while Fig. 8 to 12 show the position unlocked from latch drive element 8.

As can be seen especially by Fig. 7, in the locked position of the drive element of the latch 8 interlocking extensions 23 penetrate the interlocking housings 26 provided by bridges 29. In change, in the unlocked position, when the stirrup spring 22 has been widened because of the insertion of a key 16 and the Stirrup spring spring 22 arms are separated between yes, interlocking extensions 23 are displaced radially outward, that is to say they stop penetrating the interlocking housings provided by bridges 29, as can be deduced especially from Figs. 10 and 12. In this position unlocked, that is unlocked, of the element of latch drive 8 you have the possibility to turn East.

In latch drive element 8 a bridge 30 is arranged through which the space is rotated cancel for interlocking extensions 23, which can be deduce especially from Fig. 7 and 12.

To be able to drive safely in position the actuation element of the latch 8, it has a housing 38 located therein on the side of the lid. He actuator element of latch 8 is therefore supported on the lock housing, on the one hand by means of the accommodation 12 and on the other by accommodation 38.

Between bridge 30 on one side and the edge of the leading edge of the housing 12 an annular space is formed to interstitium mode in which in the mounted state of the lock 1 the bridges 29 formed by the inner face of the top. This prevents displacement from occurring. involuntary relative of the latch drive element 8 on the one hand and the cover 3 of the lock 1 on the other hand. For further stabilize the position of the drive element of the latch 8 with respect to the cover 3, the cover 3 has on the face inside of two other bridges 28 that in assembled state of the lock 1 surround bridge 30 located in lock washer 13 of latch drive element 8. Bridges 28 they also stabilize the extreme areas of the outside of the mouth of the key 15, as can be deduced especially from the Fig. 2. Bridges also serve in particular to prevent any insight into the lock, and therefore Avoid manipulations.

The bridges 30 arranged in the washer of lock 13 of the latch drive element 8 are each performed in an interrupted manner leaving a hole 32. This The situation is especially shown in Fig. 7 and 12. The separations 32 provided in bridges 30 represent an area of deflection for interlocking extensions 23 of the spring stirrup 22, when they pass from their locked position such as is shown in Fig. 7 to its unlocked position as shows Fig. 12.

Stirrup spring 22 serving as an element lock can carry an encoding that is not represented in the figures, so that they can only be inserted in the housing 12 of the latch drive element 8 those keys that have an encoding 31 corresponding to this stirrup spring coding 22. Therefore only a key provided with the corresponding coding 31 can therefore cause the spring opening to be separated from stirrup 22 and therefore the release of the element of latch drive 8. This embodiment is optional.

Stirrup spring 22 serving as an element Lock fulfills three kinds of functions. On the one hand the interlocking extensions 23 of the stirrup spring 22 serve to position the drive element of the latch 8 in the locked position of the lock, that is to say then there is no possibility of rotating the drive element of latch 8 when interlocking extensions 23 fit  in the interlocking housings made in cover 3. In addition to this, the stirrup spring 22 may be provided with a coding, so it is only possible to pass the spring of stirrup 22 to the unlocked position if the key is used corresponding to the lock, that is when coding 31 performed on the neck of the key 17 corresponds to the stirrup spring coding 22. The stirrup spring 22 it represents with its centering 27 also a centering means for center a key 16 inserted in the lock.

The previous explanations through Figures 1 to 12 serve to describe the invention by means of a example, and therefore should not be considered with character limiter Therefore they are also encompassed by the invention in particular those lock configurations in which the plate pins are not arranged rotatably supported around a common turning channel but they can move in horizontal and / or vertical with a translation movement (upward). It is only essential for the invention that the stirrup spring carries on the side of one of its ends some interlocking extensions that in the position closed the lock fit in some housings of interlocking made in the lock housing. This It also includes those locks in which the skewers of plates are arranged differently than rotating around A common axis of rotation.
