BG63826B1 - Key with a mobile pusher, lock and door lock - Google Patents

Abstract

The key (1) for a protective cylinder (5) with a body (3) with an elongated flat shape penetrates into the channel (8) of the rotor (4) of the cylinder (5). Parallel to the middle plane of the body (3) of the key (1) there is a transverse socket (31), which houses a movable pusher (32), which has the ability to move a limited distance and interacts with one of its transverse ends (36a) with positioning element (33). The element (33) is external to the key and is located in line with the channel (8) of the rotor (4) so as to transversely displace the pusher (32), which pushes the movable pin (18) of the rotor (4) in a position allows the rotation of the rotor (4) relative to the stator (7). The movable pusher (32) has lateral formations (40, 41) on the lateral edge of its cross-sections through planes perpendicular to the longitudinal axis of the body (3) of the key (1), in whose sides (30a, 30b) there is a slot (34 ) protruding into the socket (31) of the pusher (32). The side formations of the pusher (32) interact through the slot (34) with a movable pin (19) of the rotor (4), so as to push it into a position allowing its rotation relative to the stator (7). The relative position between the side formations (40, 41) of the pusher (32) and the associated movable pin is determined by the positioning element (33).

Description

Technical field

The invention relates to a key with a movable push, a lock and a lock that are intended for use in everyday life.

BACKGROUND OF THE INVENTION

FR 2, 492,872 discloses a key with an elongated, flat-shaped body having a socket in which a movable pusher, such as a ball, can be moved. The movable pusher socket is made in the thick part of the key body perpendicular to its median plane. It can be opened at both ends and extended from either side to either side of the key body. The ball, which acts as a movable pusher, has a diameter equal to or slightly smaller than the thickness of the body of the key in which it is located.

The known solution also includes a positioning element that interacts with the movable pusher of the key body and consists of a fixed rotary pin, which pin is carried by the rotor without axial deflection and enters the inside of the key channel. When the key with a movable push rod is inserted into the groove of the cartridge, the fixed rotor pin has a projecting end that engages in the interior of a rectangular notch in the body of the key, at the bottom of which one of the edges of the pusher socket extends. During the insertion of the key into the groove, the fixed rotor pin slides into the rectangular notch and, with the key fully inserted, the fixed rotor pin penetrates the inside of the pusher socket and displaces the movable pusher. The latter extends beyond the socket and pushes the movable rotor pin into a position that allows the rotor to rotate relative to the stator.

The presence of a movable push rod with very precise dimensions greatly complicates duplication of the key and makes it practically impossible for masters using conventional machines to reproduce the key profile. The result is increased security for the owner of such a key. In addition to the wedge between the rotor and the stator, due to the presence of the movable pusher or pushers, a variety of other known wedges can be used through pairs of rotor and stator pins that interact with both the notches on the profile edge of the key and the holes made on both sides of the key body.

The key with the mobile pusher described in the French patent works satisfactorily. With this known key, the movable pusher is located at the thickness of the key and since it has the form of a ball, its diameter must be small in order not to exceed the thickness of the key. This necessitates the construction of the push-in socket and the restraints to be of very precise dimensions, which in practice is difficult precisely because of the small size of the elements.

Due to the small length of the pusher socket, its travel is extremely small and it protrudes just short of the socket when pushed by the pin of the stationary rotor. As explained in the patent FR 2,492, 872, for a movable rotor pin connected to the movable push of the key, it is good not to project inside the channel of the cartridge, but to be inwards against the wall of the channel of the cartridge. Opening it with a pin on the cylinder of the cartridge is extremely complicated or even impossible if the pins of the movable rotor do not protrude inside the cartridge. However, due to the low travel of the movable pusher, it is essential that the connected pin of the movable rotor be level with the surface of the cartridge wall or at least slightly inward.

In order to allow the fixed rotor pin that extends inside the groove of the cartridge to pass, a rectangular groove of length from the end of the key to the opening of the movable pusher socket must be made on one of the flat sides of the key. The presence of this groove reduces the possibility of pits on the two large surfaces of the key and consequently reduces the number of possible wedges between the rotor and the stator of the cylinder.

A patent is known in FR 2, 521, 201, according to which the socket of the movable pusher is made in the main plane of the key body and opens preferably from each end to one of the two longitudinal narrow edges of the key body. The groove required to pass the fixed rotor pin projecting into the inside of the cartridge groove is made on one of the longitudinal narrow edges of the key body and thus the two side surfaces of the key body are free and thus can to make indentations. In addition, the pusher socket and the pusher have a length equal to the width of the key body, and not, as in the previous French patent, the thickness of the key body. The larger dimensions of these elements allow for greater variations in machining. Also, the movable pusher has a longer stroke in the socket so that the associated pin of the movable rotor can be positioned substantially inward relative to the wall of the cartridge groove compared to the corresponding pin described in patent FR 2,492,872.

The known solution described in вΕΑ 2,521,201 is useful and satisfactory. However, it requires the grooves mentioned above for the passage of the fixed pin, which complicates the manufacture of the key and limits the possible use of its narrow edges. In addition, the movable pusher can be projected laterally relative to the maximum transverse size of the key and as a result there is a danger that the movable pusher will touch the walls that define the rotor socket when the key enters it. In practice, a conical surface must be provided to allow the movable pusher to slide to its socket. Such a conical surface on the side of the key entry takes up the space on the axis and is visible from the outside, which makes it possible to understand that the key has a movable push.

Also known is EP 154,755, which describes a key lock having an elongated, flat shape for penetration into the groove of the cylinder cartridge, the body of the key having at its front end a zone of limited height in which there is at least one transverse socket extending transverse to the longitudinal axis of the key and parallel to the median plane of the key body open to the opposite narrow edges of the reduced zone. A movable pusher with a movable distance capability and intended to interact through one of its transverse ends with a positioning element external to the key and in a line with a longitudinal groove of the rotor cartridge groove to push with the opposite transverse end of the movable pusher pin to a position that allows the rotor to rotate relative to the cylinder stator. This avoids the use of a conical surface at the inlet of the socket of the key or grooves for the passage of the positioning element, due to the presence of the reduced area at the front end of the body of the key.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a key with a movable push-button, a lock and a lock, which will further complicate duplication of the key and give greater security to the user.

The problem is solved by a key with a movable pusher, which has a body with an elongated flat shape that penetrates the groove of the rotor of the lock. The key body is provided with at least one transverse socket positioned transversely to the longitudinal axis of the key body and parallel to its median plane, with exits on opposite narrow sides of the key. At least one movable pusher with the possibility of limited displacement transversely to the longitudinal axis of the body of the key is housed in the transverse socket, the movable pusher being able to interact, with respect to the direction of displacement, at one of its transverse edges with a positioning element, external for the key and located in line with the rotor key groove so that the movable pusher is displaced transversely to the longitudinal axis of the body of the rotor key to push the rotor internal movable pin into position HY rotation relative to the stator of the lock. According to the invention, the movable pusher has at least one lateral rib extending laterally and perpendicularly to the longitudinal axis of the key body, which lateral rib has approximately V-shaped notches formed on at least one lateral edge thereof. The planes of these notches intersect the longitudinal axis of the key body in at least one location of the portion located between the two transverse end ribs of the movable pusher. The key body has at least on one side at least one opening projecting into the transverse socket of the movable pusher. The movable push rod fins are able to interact through the openings with at least one lateral movable pin - to push it into a position allowing the rotor to rotate relative to the stator. In this case, the relative position between the lateral ribs of the movable pusher and the contacting lateral movable pins is determined by the positioning element.

Typically, the key body has at its front end a reduced height zone in which is located the transverse socket of the movable push.

The movable push rod socket is located at the front end of the key body and has outlets in a longitudinal groove formed on the narrow sides of the key body, the movable push and cross socket having a height equal to the height of the key body.

The movable pusher has the ability to move along an axis and at least one cross section thereof - through a plane perpendicular to the axis of displacement that is not caused by rotation about that axis of displacement, so that the movable pusher is deprived of the ability to rotate in its transverse socket .

Typically, the movable push rod is generally flat in shape, extending in the direction of the median plane of the key body.

The movable push has at least one side rib with cutouts on at least one of its two side surfaces, and at least one opening made in the body of the key in one line with each cut.

It is advantageous that the cutout (s) are (are) made in at least one lateral rib projecting on the lateral surfaces of the movable pusher, with each lateral rib located in a plane perpendicular to the longitudinal axis of the key body.

According to one embodiment, the movable pusher has at least one of its side surfaces two parallel side ribs with cutouts, in a line with which there are openings formed in the body of the key for the side movable pins of the rotor.

Each cutout is approximately V-shaped, open to the side surfaces of the key, and a plurality of possible contact positions with the lateral movable pin of the rotor are determined along the slope of one arm of the V-cut, allowing the position of that pin to be varied - for making the rotor rotate relative to the stator.

The movable pusher transverse socket has a blind hole in the longitudinal direction of the key body housing a longitudinal extension of the movable pusher whose lateral size is smaller than that of the blind bore - to limit the lateral movement of the movable pusher in the socket his.

The reduced height area has the same thickness (s) as that of the rest of the key body.

The transverse dimension (h) of the reduced height zone is determined to allow the movable pusher to be projected transversely with respect to the contour of that cross-section so as to resemble the body of the key when that movable pusher is in a position positioned transverse to the maximum elongated transverse socket, which position is determined by the location of the movable pusher and the transverse socket.

It is possible that the transverse size of the movable pusher is greater than the height (h) of the reduced height area and smaller than the height (H) of the key body.

The key is reversible, with the lateral ribs of the movable pusher and the openings in the body of the key symmetrical to the longitudinal axis of the key.

The invention also relates to a lock comprising a stator and a rotor in which a rectangular groove is formed - for a key with a movable push. The lock also includes a positioning element arranged in line with the keyway and interacting with the transverse end of the movable push rod and with at least one internal movable pin and a lateral movable pin mounted in radially arranged inner and outer sockets shaped in the rotor and extending in the key channel - to provide interaction with the movable pusher. According to the invention, the lock is provided with at least one lateral movable pin radially mounted in the rotor and extending to one lateral surface of the keyhole and communicating through a hole in the body of the key with cutouts of the side ribs of the movable pusher.

According to an embodiment, the positioning member is a surface of the inner cylindrical opening of the stator.

The positioning element may be an insert (or wedge) mounted in a recess in the keyway. The transverse dimension of the positioning element in line with the keyway is at most equal to the height of the space remaining between the surface of the inner cylindrical opening of the stator and the narrow sides of the area with a reduced height of the body of the key.

According to the invention, the rotor is configured to accommodate interchangeable positioning elements of various transverse dimensions to adjust the position of the lateral ribs of the movable push rod relative to the internal movable pins.

It is appropriate for the rotor to have at least one lateral movable pin in two parallel planes perpendicular to the longitudinal direction of the key groove interacting with the lateral ribs of the movable pusher.

It is advantageous to have at least one internal movable pin radially mounted in the rotor in a transverse plane passing through or adjacent to the rotor and terminating at the bottom of the key groove and interacting with the edge of the movable pusher.

The internal movable pin may be located in the median plane of the keyway.

The internal movable pin may be located at an acute angle with the median plane of the keyway.

Typically, the lateral movable pin is located at the end of the rotor, which is farther from the channel inlet.

The invention also relates to a lock which is provided with a lock according to the invention.

The advantages of the invention lie in the features of the key-forming elements as well as in the key of the key, which has made it extremely difficult to duplicate the key. In this way, greater security for the user is achieved. The movable pusher moves along an axis and at least one of its cross-sections moves through a plane perpendicular to its displacement axis, which motion is not caused by rotation about said displacement axis, so that the pusher is deprived of the possibility of rotation in the socket your own, which increases security when using the lock. Advantageous is the presence on the side surfaces of two parallel ribs with cut-outs according to one of the variants, as well as the presence of openings made in the body of the key - for the passage of the movable pins of the rotor, which increase many times the possible combinations for fixing the rotor, which increases the security of the user.

Examples of carrying out the invention

Figures 1 to 18 show one in a dimensional embodiment of the invention. Figure 1 shows a key 1, which in the standard case consists of a flat part 2 intended for gripping by the wearer and a body 3 whose shape is flat. The cross-section of the key body 3 is substantially rectangular with two side parallel parallel surfaces 3a, 3b and two narrow sides defining the upper 3c and lower 3b narrow sides of the body 3 of the key 1, these narrow sides 3c, 3d being slightly protruding, as seen in Figure 1. The upper, narrow side 3c of body 3 of key 1 has a longitudinal groove Ze formed in the median plane of body of key 3, as shown in FIG. 2.

FIG. 3 shows a lock 5 having a housing 6 in which a stator 7 is arranged, with a cross-section in the form of a ring in which a rotor 4 is mounted in the inner cylindrical opening 7a. The rotor 4 has a cylindrical shape with a common geometric axis. with stator 7 which is stationary. As can be seen in FIG. 17 and 18, rotor 4 has a channel 8 for the key 1, which channel 8 has a rectangular cross section and is slightly wider than the body 3 of the key 1 so that the latter can penetrate into the channel 8. This channel 8 for the key 1 is formed by a transverse groove extending along the entire length of the rotor 4 and open to its outer cylindrical surface through a longitudinal recess 9. The wall of the channel 8 for the key 1 against the longitudinal recess 9 represents the bottom 8a of the channel 8 for the key 1. This the bottom 8a is in contact with the outer surface of the rotor 4 with the help of two parallel with indeterminate walls 8b - Fig. 17 and 18. At the inlet of channel 8 for key 1, the rotor 4 has a projection in the form of a protrusion 10 that slides into the longitudinal groove Ze on the upper right side 3c of the body 3 of the key 1 (see Fig. 3).

In FIG. 4 shows a double lock with identical elements on its left and right. The elements of the double lock, which are similar to the elements of the single lock shown in Fig. 3, are indicated by the same numbers. The double lock has two stators 7 that are connected to a longitudinal rod 11. Each stator 7 contains a corresponding rotor 4. In a conventional manner, each rotor 4 has an external channel (indicated by 12 in Fig. 3), where with a zigher ring 13, longitudinally, the rotor 4 is fixed to the associated stator 7. In this case, a switch 14 is actuated between the two locking rings 13 which actuates the locking elements. The switch 14 is formed with flanges supported on the two axial ends of the rotors 4, as well as a medially projecting inward portion 15. In addition, the switch 14 has an actuating pin 16 extending radially to its flanges. A carrier (not shown) engages / cleaves switch 14 to / θτ rotors 4, depending on the presence or absence of a key in the corresponding rotor 4. In the middle of the longitudinal rod 11 there is an opening 17 for fixing the lock, for example, to a door.

Several locks are provided between each rotor 4 and the corresponding stator 7 so that a combination is formed which allows the rotor 4 to be rotated only when a suitable key 1 is inserted into the groove 8. These locks are provided by the internal and lateral movable pins of the rotor 4, as shown in FIG. 9, the internal movable pins 18 and the lateral movable pins 19, which are connected to the respective external movable pins 20, 21 of the stator 7. The internal and lateral movable pins 18, 19 of the rotor 4 are mounted with the possibility of sliding into corresponding ext further sockets 22, 23 made radially in the rotor 4, each inner socket 22, 23 having two sections of different diameters forming an annular step 22a, 23a. Each inner socket 22, 23 is open at its smaller diameter section to the inside of the channel 8 for the key 1 and through the larger diameter section to the outer cylindrical surface of the rotor 4. Each inner and lateral pivot pin 18, 19 there are two parts of different diameters corresponding to the two sections of the inner sockets 22, 23, in particular a stem-forming part and connected to a larger-diameter chapter 18a, 19a. Each head 18a, 19a is supported internally by a corresponding outer movable pin 20, 21 of the stator 7, which pin is formed by a hollow cup sliding into an outer radial socket 24, 25 of the stator 7. Each outer movable pin 20, 21 of the stator 7 is pressed elastically from a spring 26 to the head 18a, 19a of the inner and lateral movable pin 18,19 of the rotor 4. At a certain position of the rotor 4 with respect to the stator 7, as shown in FIG. 9, the axes of the inner and outer sockets 22 , 24 and 23, 25 respectively of rotor 4 and stator 7 are in the same line.

When the body 3 of the key 1 is not inserted into the groove 8, the head 18a, 19 of each internal movable pin 18, 19 of the rotor 4 is pressed by the corresponding outer movable pin 20, 21 of the stator 7 to the annular step 22a, 23a of the corresponding inner socket 22, 23. The depth of the section having a larger diameter of the inner socket 22,23 is greater than the thickness of the head 18a, 19a, so that the outer movable pin 20, 21 of the stator 7, when pressed, has penetrated in the larger diameter section of the inner socket 22, 23, with the diameter of the outer radial socket 24.25 being one kav to that of the section with a larger diameter of the inner socket 22, 23. As a result, any rotation of the rotor 4 relative to the stator 7 is blocked by the outer movable pins 20, 21 of the latter. Figure 4 shows a plurality of internal sockets 23 for movable pins in the rotor 4.

When the body 3 of the key 1 enters the groove 8, the inner and lateral movable pins 18, 19 of the rotor 4 are pushed back against the springs 26 of the holes (not shown) on the side surfaces of the body 3 of the key 1 or by the notches on the narrow sides of the body. 3 of the key 1. If the correct key is not used, the head 18a, 19a of the inner and lateral movable pins 18,19 of the rotor 4 protrudes into the outer socket 24, 25 of the stator 7 and blocks the rotation of the rotor relative to the stator 7. Only when key 1 occupies a suitable position and all internal and lateral the movable pins 18,19 of the rotor 4 interact with the corresponding wells, the surface between the heads of the inner and lateral movable pins 18,19 and the outer movable pins 20, 21 will be positioned on the cylindrical surface of the rotor 4 and then it will be possible to rotate it relative to stator 7 when exposed by the user to the flat part 2 of key 1. Similar wells are shown in FIG. 1 of EP 154, 755, in the prior art.

The invention also relates to the particular shaping of the key head 1, in particular the end of the body 3 of the key remote from the flat portion 2, of the key 1. The key head 1 has an area of reduced height 30 in which a transverse socket 31 extends extending transverse to the longitudinal direction of the key and thus in the median plane of the body 3 of the key 1. As can be seen from FIG. 2, the area with reduced height 30 has the same thickness as that of the rest of the body of the key 3, but the height its h (Fig. 1 A) is reduced compared to the height H of the rest o t body 3 of key 1. At both ends, the transverse socket 31 is open to the narrow sides of the reduced height zone 30.

In the transverse socket 31, as shown in FIGS. 3, 4 and 9, there is a movable pusher 32 that interacts with a positioning element 33 representing a wedge or insert mounted in a dead opening in the channel 8 for the rotor key 1. 4. This positioning element 33, in this case, an insert, is projected radially inside the channel 8 for the key 1 by a rib 33a, which has a convex surface in the middle plane of the channel 8 for the key 1, facing the projection 8a of the channel 8 for the key 1, for allow vertical displacement of the movable pusher 32 at the end of insertion of the key into the lock. The outer surface of the positioning element insert 33 closely follows the outer cylindrical surface of the rotor 4 so that it does not interfere with rotation of the stator 7. The positioning element insert 33 is properly secured to the rotor 4, in particular by tensioning in its blind hole.

As can be seen in Figs. 3 and 4, the fixation of the rotor 4 with respect to the stator 7 is provided, firstly, by a flange 28 located at one end of the rotor 4 and interacting with the stator 7, and secondly by a zucker ring 13 engaged in the groove. 12 on the outer surface of the rotor 4 to its distal end from the flange 28, with this zigzag ring 13 interacting with the end of the stator 7.

As can be seen from FIGS. 1A, 1B and 1B, on each of the side surfaces 30a, 30b of the reduced size zone 30 of the key 1 there is at least one opening 34 to the transverse socket 31. The openings 34 have an outwardly extending shape, e.g. a truncated cone shape whose axis is in line with the axis of a lateral movable pin of the rotor 4, for example pin 19, when the key 1 is inserted into the lock.

The movable pusher 32 is disclosed in detail in FIGS. 5 to 7 as a first exemplary embodiment. It includes a plate 35 located in the median plane of the body 3 of the key 1, with at each transverse end a plate 35 having a protruding edge 36a, 36b intended to interact respectively with the positioning element 33, in this case the insert, and the inner movable pin of the rotor. 4, for example pin 18. In addition, the plate 35 has a longitudinal extension 37 whose transverse dimension L is less than the height h of the reduced height zone 30, and this longitudinal extension 37 enters a blind hole in the transverse socket 31 limiting the distance of sliding movable push pin 32 and the same thus limiting it from projecting out of the transverse socket 31. The transverse dimension of this extension 37 is determined to allow the movable pusher 32 to extend partially out of the transverse socket 31 beyond the narrow sides of the reduced height zone 30, and is projected transversely to the contour of the cross-section and to the rest of the body 3 of the key 1 when the pusher is pulled out of its socket to the maximum extent.

In the manufacture of key 1, the transverse socket 31 is fully open at both transverse ends to allow the movable pusher 32 to be mounted, and after its installation, the longitudinal extension 37 of the pusher is pressed into the transverse socket 31 from the end of the key to shaped that deaf hole.

Preferably, the movable pusher 32 has a transverse dimension substantially larger than the height h of the reduced height zone 30 and less than the height H of the rest of the key body 3, but it is also possible for the pusher to be transverse a size equal to or even less than the height h of the reduced height zone 30, in which case the inner movable pin 18 of the rotor 4 may partially penetrate the transverse socket 31 of the movable pusher 32.

On each side surface of the plate 35, the movable pusher 32 additionally has a projecting side rib 38, 39 arranged in a plane substantially perpendicular to the longitudinal plane of the key 1. Each side rib 38, 39 has a cut or cut 40, 41 with V- shaped with an opening to the side walls 30a and 30b of the reduced height 30 area and extending transversely to the transverse socket 31. The recesses 40 and 41 are arranged on the side ribs 38 and 39 so that they are in line with the openings 34 to allow the side movable pins 19 of the rotor 4 to k interact with the slope of one arm of the V-section 40, 41 through the openings 34. The slopes of the V-section 40, 41 make it possible to determine a plurality of possible positions of contact with the side movable pins 19 of the rotor 4.

The notches 40 and 41 on each side of the movable pusher 32 may be positioned at different heights in the transverse direction. The notches 40 and 41 extend at least over part s of the segment formed between the two end planes P1 and P2 of the cross section of the movable pushbutton 32. In other words, the length of the cutouts is shorter than that of the movable pushbutton 32 in axial direction of body 3 of key 1.

As can be seen from FIG. 2, the transverse socket 31 of the reduced height zone 30 of the key 1 has a profile corresponding to that of the movable pusher 32.

Figure 9 shows that the movable pusher 32 is projected maximum relative to the reduced height zone 30 to the internal movable pin 18 of the rotor 4, which is located at the bottom 8a of the channel 8 for the key 1 and is in line with the transverse direction with the push-rod 32. In this position, the push-rod 32 is supported with its lower protruding edge 36a on the tip of the convex edge 33a of the positioning element 33-insert, and with the opposite protruding edge 36b - on the conical tip of the inner movable pin 18. Here, 36b penetrates the interior of the interior socket 22 of the rotor inner pin 18 18. The rotor 4 lateral pin 19 extends through the opening 34 of the reduced height zone 30 and touches its rounded tip in the center of the V neck 41 of the pusher 32 or at the bottom on the slope of the shoulder of the neckline. The socket for the other lateral movable pin of the rotor 4 is shown with a dashed line and is indicated by position 123.

An alternative embodiment is shown in Figure 10. The inner movable pin 18 is replaced by a pin 118 forming an acute angle with the median plane of the channel 8 for the key 1. This internal movable pin 118 also extends to the bottom 8a of the channel 8 for the key 1 and is supported on one side of the protruding rib 3bb. the movable pusher 32. The inner movable pin 118 has a rounded tip. Its length is substantially greater than that of the inner movable pin 18 because the tip of the inner movable pin 118 is not supported by the tip of the protruding rib 3bb of the movable pusher 32.

In FIG. 13 the positioning element 33 insert or wedge - is replaced by another type of positioning insert 133 which has a convex rib 133a of smaller height. Therefore, the upper protruding edge 3bb of the movable pusher 32 is positioned at a different height relative to the transverse socket 31 of the reduced height 30 of the key 1. Thus, the inner movable pin 218 of the rotor 4, which is located in the median plane of the channel 8 for the key 1 , is longer than the inner movable pin 18 to allow the lock to be unlocked when its conical tip contacts the edge 16b of the movable pusher 32.

By moving the movable pusher 32 down over the reduced height zone 30, the lateral movable pin 119 contacts the cutout 41 of the movable pusher 32 in a different position. In FIG. 13, the lateral movable pin 119 is in contact with half of the slope of the V-section 41. Therefore, the lateral movable pin 119 should be shorter than the lateral movable pin 19 referred to in the previous exemplary embodiment of the invention.

According to another alternative embodiment shown in FIG. 14, a modified inner movable pin 318 is used, which is inclined relative to the median plane of the channel 8 for the key 1 and is in contact with the rib 3bb of the movable pusher 32, similar to the inner movable pin 118 shown in Fig. 10.

The positioning elements 33 and 133, in this case inserts, have longitudinal ribs 33,133b on each side of the convex rib 33a, 133a, which are arranged in opposite directions perpendicular to the median plane of the channel 8 for the key 1, and serve to enter a connected socket on the rotor 4.

In FIG. 17 the positioning elements 33 and 133, in this case inserts, are omitted, and for the positioning element for the lower rib 36a of the movable pusher 32, the surface of the inner cylindrical opening 7a of the stator 7 serves. The movable pusher 32 extends as far down as the edge of its upper end. 3bb is equal to the upper narrow edge of the reduced height zone 30 of the key 1. Therefore, the inner movable pin 418 of the rotor 4, which is located in the median plane of the channel 8 for the key 1, must be longer than mentioned in the previous one. example internal movable pin 218 .

When the movable pusher 32 is completely moved down, the lateral movable pin 219 of the rotor 4 is supported on the top of the slope of the V-shaped cutout 41 of the movable pusher 32. Therefore, the lateral movable pin 219 must be shorter than the analogous pin 119 according to the previous example. .

9 to 18 it is apparent that the length of the movable pins of the rotor 4 may vary in the area of reduced height 30 of the switch 1, depending on the height of the positioning element 33,133, in particular inserts, due to the cutouts 40, 41, which define a plurality of different degrees of insertion of the pins in the key 1. The length of the lateral movable pins 19, 219 of the rotor 4 may vary in the same way as a function of the inclination of the pins relative to the upper rib 36b of the movable push 32. this way of becoming an unauthorized person It is more difficult to duplicate the key, as it cannot know the degree of entry of the lateral movable pins 19, 219 in the reduced height zone 30 of the key 1. In this way, multiple positions for the lateral movable pins are obtained with one movable pusher 32. pins 19, 219 and internal movable pins 18, 218 of rotor 4. In addition, the height of the positioning element 33,133 is variable according to the various embodiments.

Fig. 8 shows a movable pusher 132 in accordance with another alternative embodiment. The elements of the movable pusher 132 are similar to the elements of the movable pusher 32 according to the examples described above, which is why they are marked with the same positions but plus 100. The movable pusher 132 differs from the pusher 32 only in that the notches 140 and 141 have V- a truncated base or a C-shaped with divergent side arms. Here, the truncated base of the V-shape is slightly inclined relative to the transverse direction of the movable pusher 132.

Figures 19 to 24 illustrate another embodiment of the invention. The elements, which are similar to the elements of Figures 1 to 7, bear the same positions plus 200. On each side surface of the tile 235 of the movable pusher 232 there are a pair of parallel side fins 238, 258, and 239, 259, respectively. notches 240, 260, are 241, 261. Like the notches 40 and 41 of the movable pusher 32, the cutouts of the movable pusher 232 are V-shaped, with one arm more inclined than the other relative to the median plane of the movable pusher 232. Preferably is the side ribs 238 and 239 located on either side of the movable pusher 232 to be m in one plane perpendicular to the longitudinal axis of the key 1. Similarly, the side ribs 258 and 259 on each side of the movable pusher 232 are arranged in a plane perpendicular to the axis of the key 1. Preferably, the notches 240 and 260 of the two respective side ribs 238, 258, which are located on the same side of the movable pusher 232, are in opposite directions. In other words, the longer arm of the V-section 240 is oriented downwards and the longer arm of the V-section 260 is oriented upwards.

The body 203 of the key 1 has a socket 231 in the reduced height zone 230, the cross section of which is correspondingly to the movable pusher 232.

The protruding ribs 36a and 36b of the movable pusher plate 35 are not shown in the movable pusher 232. The ribs 238, 239, 258 and 259 extend transversely beyond the edges of the plate 235 to serve as points of contact with the internal movable pins. 518 of the rotor 4. Compared to the example shown in Fig.24 with Fig.7A, it is seen that the ribs 36a and 36b of the movable pusher 32 are replaced by protruding parts 238a, 239a and 238b, 239b, at the transverse edges of the side ribs 238, 258 of pusher 232. The transverse edges of the ribs form a lower longitudinal groove 262a and upper longitudinal groove 262b.

A transverse groove 263a and 263b is formed between each pair of side ribs 238, 258 on one side of the movable pusher 232.

As shown in FIG. 25, the inner movable pin 518 is supported at the upper end 239b of the lateral rib 239 of the movable pusher 232, and the lateral movable pin 219 is supported at the top of the cutout 241 of the same lateral rib 239. A dashed line is shown the position of the inner socket 122 of another internal movable pin of the rotor 4, which is inclined relative to the median plane of the channel 8 for the key 1 on the side against the socket 22. The internal movable pin (not shown) located in the socket 122 may be designed to interact with upper transverse end 258b of s the cutting edge 258 located in a plane parallel to the plane of the side edge 239.

Although not shown, the movable pusher 232 can be used equally well with the other locks illustrated in Figures 9 to 17.

The openings 234 of the reduced height zone 230 of the key 1 are not shown in FIG. 19, but can be seen in Fig. 25.

FIGS. 26 and 27 illustrate an alternative embodiment of the movable pusher according to FIGS. 21 to 25. FIG. 26 and 27, the elements of the movable pusher 332 are similar to the elements of the movable pusher 232, and are therefore designated by the same numbers plus 100. According to the exemplary embodiment, the movable pusher 332 differs from the pusher 232 in that the upper longitudinal groove 262a and the lower longitudinal groove 262b of the movable pusher 232 are replaced by a convex surface 362a, 362b located between the respective lateral edges of the side ribs (without marking) of the movable pusher 332. In Fig. 26 it is seen that the inner movable pin 518 is supported in a projection 518. and the surface 362b of the movable pusher 332, while the lower convex surface 362a of the movable pusher 332 is supported at the surface of the inner cylindrical opening 7a of the stator 7.

Another alternative embodiment of the movable pusher 32 is illustrated in Figures 28 to 29. On them, elements similar to those of the movable pusher 232 bear the same designations plus 200. The lateral ribs 438, 439 and 458, 459 of the movable pusher 432 have a common shape identical to that of the lateral ribs 138 and 139 of the movable pusher 132 illustrated in FIG. As in the previous exemplary embodiment, the movable pusher 432 has, at both transverse ends of the plate 435, protruding edges 436a and 436b intended to interact, respectively, with a positioning element and an internal movable pin of the rotor 4 (not shown).

The action of the lock according to figures 1 to 3, 5 to 7 and 9 is as follows.

When the body 3 of the key 1 is pulled out of the channel 8 for the key 1 of the rotor 4, the latter becomes immobile with respect to rotation about its axis relative to the stator 7, due to the fact that the outer movable pins 20, 21, as explained above, partially issue in the internal sockets 22, 23 of the associated internal movable pins 18,19. The inner ends of these internal movable pins 18,19 are in the form of a truncated cone or are rounded, as shown in FIG. 9, and protrude into the interior of channel 8 for key 1.

When the body 3 of the key 1 is inserted into the channel 8 for the key 1 in order to rotate the rotor 4 and activate the lock, it will cause the internal movable pins 18 to be retracted into their respective internal sockets 22, 23.

Shortly before the end of the insertion of the key 3 body 1 into the key channel 8, determined by the moment the arm 2a of the key 1 body 3 rests (FIG. 3) on the rotor face 4, the movable pusher 32 enters contact through its lower protruding rib 36a with a convex portion 33a of the positioning element 33 (FIG. 9), made as an insert or wedge. Then the movable pusher 32 adopts the position illustrated in FIG. 9, with its upper rib 36 extending from the transverse socket 31 of the reduced height zone 30, pushing back the inner movable pin 18 of the rotor 4 at a distance sufficient to displace the contact surface between the inner movable pin 20 and the inner movable pin head 18a. 18 at the boundary surface between the rotor 4 and the stator 7. At the same time, at this position at the end of insertion of the key, the lateral movable pin 19 will be pushed back from the slope of the V-notch 41 of the movable pusher 32 to a position that allows rotation of years 4. In the position at the end of insertion of the key, all other internal movable pins 18 located on the rotor 4 interact with the associated recesses in the body 3 of the key 1 to allow rotation of the rotor 4. It is now possible by exercise torque on the flat part 2 of the key 1 to rotate the rotor 4 relative to the stator 7 and to activate the lock.

It should be noted that when insertion of key 1 into channel 8, the movable pusher 32 may extend beyond the narrow sides 3c and 3d of the body 3 of the key 1. There are sloping sides x on the ribs 36a and 36b that allow positioning of the key 1 in Channel 8.

It is very difficult to open the lock of the lock according to the invention due to the presence of many radially arranged pins in all directions and the system of the movable push 32 at the end of the key 1.

Although the invention has been described in connection with many specific embodiments, it is readily apparent that it is not limited to them and that it encompasses all the technical equivalents of the agents described together with their combinations, if the latter fall within the scope of the invention.
