Description

i The invention relates to a hidden lock of robust design, realizing

a closure in four

directions and in five points.

  Many types of hidden locks of robust design are manufactured in the world. For the realization of the lock mechanisms most similar to the present invention, what is characteristic is that these mechanisms close and open only in one direction. with the so-called deadbolt Different types of such "sturdy design hidden locks" are commercially available. The common feature of sturdy design hidden locks, which are part of the state of the art and are commercially available, is that all these types of locks lock in the same direction as the basic lock. practical, it has been found that these locks do not withstand the various burglary methods at the doors, since the doors can be opened for example by using crowbars or systems

lifting.

  Due to the aforementioned drawbacks

  As hidden closers of a robust design, it is a widely used practice in the world to install so-called several security locks of different types in the doors in order to complete the

  sturdy design hidden lock.

  This practice widely used in the world, which consists of mounting, next to the basic lock

  other locks known as security locks

  rity, however, does not, as is known, provide corresponding security against burglary opening of the door, since, in accordance with common practice, the other individual security locks mounted next to the lock concealed robust design are mounted together on the same side of the door

than the hidden lock.

  Practice has shown that different systems

  keyholes, mounted on the same side of the door, do not resist violent burglary methods since the doors can be opened for example using

  Presser feet or lifting device

  In addition to other break-in methods which are also known, the side of the door is sawed, on which the concealed lock of robust design and the locks are mounted.

  security, which opens the door.

  The object of the present invention is to arrange such a concealed closure of robust design, which closes in four directions and at five points and is able, by means of the use of a single lock mechanism, to produce a blocking in four directions in the opening housing, i.e. to realize

  blocking with the latch bolt of the simultaneous lock

  in five points by actuating a

only key.

  Blocking of any door in at least two directions has already been resolved in accordance with

  the state of the art, for example in the case of

  rures of cupboards or armored doors In the case of locks of cupboards, the blocking is carried out in general with a rod extending in the vertical direction, the opening with a key in the case of armored doors

  releasing only the deadbolt, which blocks the elements

  closing elements moved separately.

  We do not know a built-in structure of robust design, which closes in four directions,

  in five points, and who can assume multiple functions

multiple indicated below.

  9 As is known, the role of the latch bolt, which is traditionally used in doors, is to lock without the use of a

  key or other actuation systems in the sheet-

  lure of the door, against the pressure of a res-

  sort The latch turn latch can usually be released using a key or a ratchet, possibly by means of a button.

  such an embodiment of the lock bolt, in the-

  which, to promote the locking of the latch bolt, a drive tongue is used, which is mounted

in the block of the latch bolt.

  The novelty of the present invention lies in the

  fact that the lock latch can be turned

  separately on both sides, so that a space can be simultaneously reserved for other components inside the lock To achieve this objective, we install, instead of the

  usual known rod of the latch bolt a fork if-

  killed on the rod of the latch bolt, which makes it possible to provide a corresponding free space around the rod of the latch bolt for the split ratchet nut,

  which activates the bolt of the lock.

  The subdivided ratchet nut, which actuates the latch bolt, is arranged so as to include an external blocking system In door locks, the role of the latch bolt is traditionally to prevent the opening of the lock

  from the outside ratchet or the outside button.

  The solution from the construction point of view is essentially based on the fact that two independently actuated ratchet nuts are used, which guarantees that, in the case of a rotation of the square or of the shaped groove, formed in the follower, the latch turn latch and also possibly also the deadbolt of the lock can be actuated by means of transmission elements Thanks to the use of the subdivided ratchet follower, one of the following can be made independent the other the opening from the inside and the opening from the outside using a ratchet or a button. In the solutions according to the invention, the novelty lies in the fact that the mechanism fixing the ratchet nut can be rotated or adjusted, before mounting the lock, in the direction of a blocking to the right or a blocking to the left From this point of view, the arrangement of the mechanism fixing the ratchet nut near entes a character of novelty. In the case of doors fixed by means of the use of an auxiliary bolt and a corner of the latch bolt, which block the latch bolt of the lock, it is usual that the actuation of the pawl or of the button is prevented from outside and a problem is that the lock bolt must resist illegal attempts to break in between the door and the housing Indeed, when the door is closed, the bolt

  is lowered into the front plate of the

  nism of the lock and therefore cannot be hooked because the latch bolt of the lock is stuck in cooperation with its corner In the arrangement according to the invention, a novelty lies in the fact that the corner fork, which cooperates with the auxiliary bolt, must be able to block the fork of the latch bolt by a wedge action using the wedge

  of the latch bolt, which cooperates with this fork.

  * It is intended that the actuation of the deadbolt of the built-in lock according to the invention is carried out using a cylindrical insert or by means of the interior button, the arrangement of the fork actuating the deadbolt being of usual type, that is to say that the fork can be actuated directly by means of the square located in this fork or else by means of the bore having another shape and formed in the

  fork or using the button.

  The actuation of the locking linkage directed in several directions occurs simultaneously during the actuation of the deadbolt In locks

  of traditional cupboards, in general one can action-

  Locking linkages in two directions simultaneously, whereas in the case of armored cabinets, locking links can be operated in three directions without the deadbolt or simultaneously with the deadbolt There are also solutions,

  in which the linkages are actuated

  automatic lesson and only the closed position

  is fixed with the lock The deadbolt of the ser-

  rure can also constitute in itself a point of fixation

  tion In the case of cabinet locks, the lock mechanism actuates two linkages From the point of view of the lock mechanism according to the invention, a novelty consists in that the problem consisting in being solved as well moving the deadbolt in different directions than moving

  linkages in different directions are pos-

  sibles during the actuation of the deadbolt of the lock, simultaneously with the use of the same actuator With regard to the solution of this problem, the invention provides a novelty from the construction point of view by the fact that discs are used which move the bars and are mounted on the disc which moves the linkages and is connected to the

deadbolt of the lock.

  No lock is known, the operation of which

  allows the release of the deadbolt activated by the

  of a cylindrical threaded insert of the lock, and of the linkage The novelty of the solution lies in

  actuation of the deadbolt using the cy-

  the threaded indrique of the lock or of the interior button or else in the actuation of the locking linkage directed in several directions, together with

actuation of the deadbolt.

  A simultaneous recoil is planned, controlled by a click

  quet, deadbolt and a release of that deadbolt or the deadbolt linkage

(actuation in case of panic).

  Two standards are currently known which prescribe

  Also write, for locks, several functions or grouped functions, making it possible to eliminate the multiple blocking of the lock mechanism for example in the danger position, using a single movement from the inside. standard prescriptions, a novelty of the embodiment of the lock mechanism according to the invention lies in the fact that the other end of the arm, which cooperates with the ratchet nut and actuates the latch bolt, can be connected to the emergency actuation arm mounted on the fork which moves the deadbolt, when this fork is in the closed state Consequently, the actuation arm of the deadbolt, which is driven in forced displacement by the f ouotot , drives the bolt in the open position and simultaneously drives in the open position the fork, which moves the deadbolt, under the effect of the rotation of the actuating arm

  mounted on the fork moving the deadbolt.

  As a result, the deadbolt of the lock and the locking linkages, which are connected to it, are

  brought to the base-open position.

  Consequently, the present invention relates to a hidden lock of robust design, which closes

  in four directions and in five points and in the box

  third of which are fixed a stop support, screw housings, a support axis, a guide for the

  bolt, and in which the plate fixing the

  cylindrical serves the lock is arranged in the bowl

  tier, a spring from the corner of the latch bolt is fixed with a fixing ring on a screw housing; locking bolts are forced into the latch

  frame located in the housing, the half bolt mechanism

  lathe, which constitutes the latch bolt of the lock, is constituted by a head, an insert, a fixing bolt, an axis of the latch bolt, a support for a spring of the latch bolt, this spring, a split adapter socket and a rod of the latch bolt, an insert of the ratchet nut is arranged in the hole of the ratchet nut connected to a rotary ratchet, the mechanism which actuates the latch bolt, is constituted by a spring, arms actuating the latch bolt, fixing rings and

  furthermore a shoulder pin mounted on the buoy support

  tee and an upper arm moving the latch bolt, the actuating element of the deadbolt of the lock mechanism is formed by a fork, which moves the locking spring and includes spacers or emergency actuation arms , and the pawl fixing system includes a mechanism consisting of an insert for fixing the ratchet nut, the axis of this insert, a

fixing bolt and a spring.

  The novelty from the construction point of view of the hidden lock of robust design according to the invention, which closes in four directions, consists in that the mechanism of the corner of the latch bolt comprises a fork, on which a corner insert of the latch bolt is mounted by means of a corner bolt

  bolt, that in addition the mechanism of the half bolt

  tower is a mechanism formed by the meeting of the rod

  of the latch bolt made in the shape of a fork, of the

  emerges from the corner plate of the latch bolt, and from the shoulder bolt, that in addition the mechanism, which moves the bars, is formed by the disc, which is mounted on the insert of the ratchet nut and moves the bars, by the plates, which move the bars, and by a connecting bolt, that in addition the components, which actuate the latch turn, are supplemented by springs, by arms, which actuate the latch bolt, and by fixing rings, and that in addition the mechanism for fixing the ratchet nut is formed by fixing arms and

by a shoulder bolt.

  The most important advantages of the farm-

  robust hidden design, in accordance with the invention

  tion, which closes in four directions are the following

  doors: The door can be locked in all directions using the lock mechanism, which is operated using a single key;

  This lock meets the static and dy-

  namics for all locks; This lock meets the requirements prescribed in the standards of different countries, with regard to its opening in a panic case;

  From the point of view of protection against an ef-

  fraction, this lock solves in a new way the fixing of the latch bolt and the limitation of the opening of the pawl, thanks to the subdivided arrangement

of the follower.

  In the bore of the abutment support 2 is located the shoulder pin 40, which includes the upper arm 39

  actuating the latch turn in the space 1 / f of the box

  tier 1 is arranged the mechanism constituted by the fork 37 moving the deadbolt, the support forming a spacer 36 and the emergency actuation arm 38, the locking in position of this mechanism being guaranteed by the locking spring 42 mounted on the deadbolt 35 The mechanism consisting of the 1st arm 43 for fixing the ratchet nut, the 2nd arm 44 for fixing the ratchet nut, the shoulder bolt 45, the insert

  46 for fixing the ratchet nut, the fixing bolt

  The complete lock mechanism, constituted in the manner indicated above, is closed by the closure plate 61 with the aid of a screw fixing. In FIGS. 2 a to 2 g, there is shown the lock mechanism mounted in accordance with the invention, the components of which have been

  already described in detail during the description

  tion of Figure 1 The other components shown in Figures 2 a to 2 g are as follows: In Figure 2 g, there is shown in the assembled state the arm 51 for releasing the attachment of the nut, the housing 52 of the fork bolt 53, this

  bolt, release arm 54, spring 55

  release release, spring 56 of the bolt half

  tion 64 is provided at the lower part of the front plate 63 of the lock mechanism -as visible

  in FIG. 2 a In FIGS. 2 a to 2 g, we have represented

  felt the 65-68 screws used as other fasteners.

  In FIGS. 3 a to 3 g, the metal has been shown.

  lock mechanism in the assembled state, the latch bolt and

  the components operating this U-bolt being shown

  felt in a heightened way by a thick line in the basic position The representation in the position of

  base is identical to the device shown in f i-

  gures 2 a to 2 g, and the use of a thick line to represent

  raising the representation in the basic position aims to represent these components in the basic position, that is to say the closed position, relative to the

  open position shown in Figures 4 a to 4 g.

  The components, which have been brought out in FIGS. 3 a to 3 g, operate in the following way: When the ratchet nut 18 is rotated clockwise or counterclockwise of a watch, the arm 9 for actuating the half-bolt moves in the direction of the rear face of the lock mechanism and the arm 9, which actuates the latch turn, simultaneously pulls the latch mechanism backwards U-turn, which is constituted by the rod 27 of the U-bolt, the head 20 of the U-bolt, which is mounted on this rod, the insert 21 of the U-bolt, the fixing bolt 22, l axis 23

  of the latch bolt and the split adapter sleeve 26.

  In FIGS. 4 a to 4 g, the po-

upper actuation position.

  When the force turning the ratchet nut 18 is removed, the spring 25, which is supported by the guide 41 of the latch bolt, pushes the latch mechanism back to its initial basic position It is then brought back to the operating state shown

in Figures 3a to 3g.

  In FIGS. 5 a to 5 g, the metal has been shown.

  lock mechanism in the assembled state, in which case the subdivided ratchet nut, which actuates the bolt of the lock, is shown in a raised manner by a thick line, in the case where the blocking mechanism is

open state.

  The split ratchet nut, which operates

  the latch turn latch, works respectively

  with a blocking on the outside On the fi-

  gures, we can see, for example in the position of

  base, the system, which blocks the ratchet nut subdi-

  aimed 18 and allows specific actuation or rotation

  particular part of the two elements of the whole

  ratchet follower 18 formed by two followers (see the

  description of Figures 3 a to 3 g) During the compression of the upper edge of the fixing insert 46 of the ratchet nut, which rotates around the axis 47 of the nut, in

  direction of the lock mechanism, the mechanism con-

  held by the 1st fixing arm 43 of the click nut

  quet, which is connected to the shoulder bolt 45, the 2nd fixing arm 44 of the ratchet nut and the shoulder bolt 45 also moves from said basic position, and the rear edge of the 1st arm of attachment 43 of the ratchet follower snaps into the keyway of a member of the ratchet follower 18 Therefore, the ratchet follower 18 cannot rotate from the direction corresponding to one side of the assembly of lock This operating state is represented in FIGS. 6 a to 6 g, which represent the lock assembly in the assembled state, the split ratchet nut, which actuates the latch bolt of the lock, being represented by a way enhanced by a thick line, in the case where the lock assembly is

  in its interior blocking state.

  In FIGS. 7 a to 7 g, there is shown from

  way enhanced by a thick line the follower

  subdivided quet, which activates the latch turn of the ser-

  rure, when the lock assembly is in the state of

external blocking. We can see in Figure 1 that the mechanism consisting of the 1st arm

  fixing 43 of the ratchet follower, by the 2nd fixing arm 44 of the follower to

  ratchet and by the shoulder bolt 45, can also be

  lement mounted by being pivoted by 180, in the fixing insert 46 of the ratchet nut, by means of the withdrawal of the

  fixing bolt 48 The purpose of this mounting is to

  see adjusting the position K of the fixing arm 43 of the ratchet follower in the lock, according to the desired side of the closure, and so as to be able to thus block the subdivided ratchet follower 18, taking

account of the above.

  In FIGS. 8 a to 8 g, the metal has been represented.

  lock mechanism in the assembled state, the position in the open state of the auxiliary latch bolt, which blocks the latch bolt of the lock, and of the corner of the latch bolt being shown in a raised manner using a

  thick line In the figures, the

  latch bolt mechanism (see Figures 3 a to 3 g) and in addition the plate 28 of the corner and the plate 29 of the corner of the

  U-bolt, which are mounted on the men-

  of the latch bolt, and in addition there is shown, in the basic position, the mechanism of the corner of the latch bolt, which is constituted by the fork 31 of this corner, the spring 32, the insert 33 and the bolt 34 When closing the door, the counter plate E, which is fixed in the door frame, pushes the mechanism of the corner of the latch bolt against the spring 32 of the corner of the latch bolt, under the effect of the displacement of the insert 33 from the corner of the latch bolt, in the mechanism of the lock In this position, the spring 28 of the plate 29 of the corner of the latch bolt lifts this plate, this rotation taking place around the bolt with shoulder 30 in the hollowed out part of the fork 31 of the corner of the latch bolt This entails that the attempted break-in, which would be carried out by driving a tool between the door and the frame of the door and by means a backflow of the latch bolt mechanism, would remain unsuccessful due to the fact that the plate 29 of the corner of the latch bolt remains in the position fixing the head 20 of the latch bolt This fixed position is represented in FIGS. 9 a to 9 g The mechanism of the latch bolt can be released from this fixed position, in the way

  described with reference to Figures 3 a to 3 g.

  In Figures l Oa to Og, there is shown the mechanism of the lock in the assembled state, the fork, which actuates and moves the deadbolt of the lock, the

  disc, which is connected to the lock mechanism and

  places the bars, and the plates, which connect to this disc and move the bars, being represented by a thick line in the open base position The purpose of the actuation is to cause the blocking bar extending in several directions, which is operated

  simultaneously during the blocking operation On the fi-

  gures i Qa à l Og, we have represented in the basic position

  the deadbolt 35, the fork 37 moving the deadbolt

  mant, the locking spring 42, the disc 12 which is connected

  strung to deadbolt 35 and moves the bars, and

  in addition to the mechanism connected to the disc mentioned above

  deny place by connecting bolts 17, and constituted by the 1st plate 13 which moves a bar, the 2nd plate

  which moves a bar and the 3rd plate 16, which

* places a bar In the case of a fork rotation

  37, which moves the deadbolt in the opposite direction to the ai-

  guilles of a watch (out of approximately 110), the fork 37, which moves the deadbolt 35, brings the latter out of the lock. Consequently, the application profile provided on the deadbolt 35 rotates, jointly with the disc groove 12, which moves the bars, in the

  clockwise therefore the first

  first plate 13, which moves the bars, moves in

  the direction facing away from the front plate of the mete

  lock mechanism, the 2nd plate 14, which moves a bar, goes up and the 3rd plate 16, which moves a bar, goes down The mentioned rotation of 110 of the

  fork 37, which moves the bars, is symmetrical

  only 55 to the right and 550 to the left, relative to the vertical axis of the lock mechanism Ces

  external positions are fixed by the block spring

  cage 42 and consequently the fork 37 of the locking spring blocks, in the application profile, which extends respectively over 450 to the right and to the left with respect to the vertical axis of symmetry of the deadbolt

  , this bolt in the open or closed position and the

  canism, which connects to it and moves the bars.

  This closed state is shown in the figures

  lia à llg As can be seen in the figures, the pro-

  deadbolt wire 35 supports the head 20 of the half-bolt

  turn when the deadbolt is in its closed position, and thus the head 20 of the half-turn bolt forms the fifth point of closure in the case of a blocking of the lock mechanism The lock mechanism can be released from the position blocked, by turning the fork 37, which moves the deadbolt, in the opposite direction (clockwise) The swivel fork 37 can be rotated using the rotary button, which is installed in the groove (cavity)

  of the fork 37 which moves the deadbolt.

  In Figures 12 a to 12 g, there is shown the lock mechanism, which has been brought out by means

  with a thick line the completely blocked position, that is

  i.e. a position corresponding to the actuation of the

  locking linkage that extends in several directions

  and is operated jointly during

actuation of the deadbolt.

  In Figures 13 a to 13 g, there is shown

  opening the lock from the operating position

  defect not shown in Figures 12 a to 12 g, by

  through a push-forming drive

  evening T of the insert in the form of a cylindrical rod By means

  of a rotation of the drive member forming

  evening T and anticlockwise - which can be done from the outside of the door using a key -, the drive member T rotates the fork 37, which moves the deadbolt, clockwise This action

  causes the release of the deadbolt, described in ref-

  Reference to Figures 11a to 1g The upper arm 39, which cooperates with the bolt of the deadbolt 35 and moves the latch bolt, rotates around the shoulder axis 40, and the upper arm 39, which moves the latch bolt ,

  comes in the open position of the latch bolt.

  When the organ continues to rotate

  drive forming pusher T in opposite direction to the ai-

  watch watch, this organ pushes back the shoulder

  adjoining upper arm 39, which moves the bolt half

  turn, the rod of which pushes the rod 27 of the latch bolt backwards and consequently brings the mechanism of the

  latch in the open position.

  In Figures 14 a to 14 g, there is shown

  this position, i.e. the opening of the half bolt

  turn of the lock from the position shown in FIGS. 13 a to 13 g, in which the deadbolt is open, thanks to the use of a cylindrical insert, or the open position of the bolt

the lock.

  In FIGS. 15 a to 15 g, the particular operation of the lock mechanism is illustrated, that is to say the simultaneous operation of withdrawal of the bolt

  turn around and release the deadbolt or the trin-

  deadbolt glery, which is triggered by a ratchet or a button (operation in the event of panic, i.e. complete opening of the lock by means of a single movement) During rotation of the ratchet nut 18, which can be actuated by means of a button or a ratchet, clockwise

  or in the opposite direction, arm 9, which activates the half bolt

  turn, moves towards the rear wall of the met

  lock mechanism (opening direction) Under the effect of this action: a) the latch bolt mechanism moves in the direction

  of the opening (see Figures 3 a to 3 g), and simultaneously

  ment, b) the emergency actuation arm 38, which is mounted

  in the lock and is keyed onto the fork 37

  placing the deadbolt, turns clockwise

  watches of a watch; during simultaneous rotation

  actuating arm 38 and fork 37 displaced

  erasing the deadbolt, the lock mechanism opens (see figures 12 a to 12 g); in the case of the use of the last mentioned system, the closing mechanism can be brought from the fully locked position to the fully open position by means of the single movement described above; this corresponds to the requirements for opening in the event of panic.

Claims (1)

CLAIM   Hidden lock of robust design, which closes in four directions and at five points and in the housing (1) of which are fixed a stop support (2), screw housings (3,4,5), a pin support   (7), a guide (41) for the latch bolt, and in the-   which; the plate fixing the cylindrical insert of the ser-   rure is arranged in the housing, and the spring (32) of the corner of the latch bolt is fixed with a ring of   fixing (11) on a screw housing; block bolts   cage are force-fitted into the deadbolt (35) located in the housing (1), and the mechanism of the half-turn bolt, which constitutes the half-turn bolt of the lock, consists of a head, an insert (21) , a fixing bolt (22),   an axis (23) of the latch bolt, a support (24) of a spring   out (25) of the latch bolt, this spring, a closed socket   due for adaptation (26) and a rod (27) of the latch bolt; an insert (19) of a ratchet follower (18) is disposed in the bore of the ratchet follower connected to a rotary pawl, and the mechanism which actuates the latch bolt, is constituted by a spring (10), arms (9) actuating the latch bolt, fixing rings (11) and in addition a shoulder pin (40) mounted on the stop support and an upper arm (39) moving the latch bolt; the deadbolt actuating element of the lock mechanism is formed by a fork, which moves the locking spring (42) and comprises spacers (36) or emergency actuating arms (38), and the ratchet fixing system comprises a mechanism consisting of an insert (46) for fixing the ratchet nut, the axis   (47) of this insert, a fixing bolt (48) and a res-   spell (49), characterized in that the mechanism of the corner of the latch bolt comprises a fork (31), on which an insert (33) of the corner of the latch bolt is mounted by means of a bolt (34) from the corner of the latch bolt, that in addition the latch bolt mechanism is a mechanism constituted by the union of the rod (27) of the latch bolt made in the form of a fork, of the spring (28) of the plate (29) of the corner of the latch bolt, and of the shoulder bolt (30), that in addition the mechanism, which displaces the bars, is formed by the disc (12) which is mounted on the insert (19 ) of the ratchet nut and moves the bars, by the plates (13,15,16), which move the bars, and by a connecting bolt (17), that in addition the components, which   operate the latch bolt, are supplemented by   spells (10,58), by arms (9,57), which activate the latch bolt, and by fixing rings (11), and   that in addition the fixing mechanism of the clicker   quet is formed by fixing arms (43,44) and by a shoulder bolt (45).
