Description

445338 V. Description of the invention (1) Background of the invention The present invention relates to a key having a movable drive for 1 week on the key's security lock core and the lock or latch having the lock core. French Patent No. 2, 4 9 2 ^ In No. 8 7 No. 2, a key is described in which the body of the slender flat shape has a body in which a movable actuator such as a ball can move within a limited movement range. The seat of the movable driver is made on a thick part of the key body > on a plane perpendicular to the middle of the key body. It can be opened at both ends, and extends to the large surface of the key body on each side. The ball, which functions as the same movable actuator, has a diameter substantially equal to or slightly less than the thickness of the key body, and the ball is installed therein. In the aforementioned French patent, a positioning element interacting with the movable actuator of the key body may include a fixed rotor pin, in other words a pin pushed by the rotor, without the possibility of axial deviation, and Protrude into the key slot. When the key with the movable driver is fully pushed into the interior of the key slot, the protruding end of the fixed rotor pin is engaged with the inside of the cut made in a straight line on the key body and enters the bottom of the open end of the driver base ; While the key is introduced into its base, the fixed rotor pin slides in the cut made by the straight line, and once the key is fully inserted, the fixed rotor pin penetrates into the interior of the driver base and replaces the movable driver ; The latter protrudes beyond its base and advances a movable rotor pin to a position that allows the rotor to rotate about the stator. The dimensional characteristics of the movable driver are very accurate, which makes the copying of the key installed in it more difficult, and the

Page 6 5 'Explanation of the invention (2) It is almost impossible for a mechanic who duplicates the side of a key with a traditionally designed mechanical duplication key to complete such duplication. As a result, the use of such keys is increased. Of course, in addition to the way of locking between the rotor and the stator by the action of one or more of the movable key drives, it is also possible to provide a variety of other known locking methods by using multiple pairs of rotor and stator pins. At the same time, it interacts with the teeth on the side edge of the key and the hollow sawtooth made on the two large faces of the key body. The key of the aforementioned French patent with a movable drive is generally satisfactory, but nevertheless exhibits three disadvantages. First, the movable driver is located on the thick part of the key, and since it is a ball, its diameter must be small because it must not exceed the thickness of the flat key. However, it is necessary to manufacture the driver base and the full-foot-to-foot stroke end stop, and because of the small size of these components, it causes substantial difficulties. Second, because the driver base is very short, the driver can only have extremely short strokes, and therefore only slightly protrudes from its base when pushed by the fixed rotor pin. As explained in French Patent No. 2, 4 92, 8 72, it is particularly useful for the movable rotor pin associated with the movable drive of the key body, which does not protrude into the interior of the key slot However, it is configured to retract the wall of the key slot 13. If the movable rotor pin does not protrude into the key slot, it is very difficult, or even impossible, to pry the lock. However, because the movable actuator has a very short stroke, the associated movable rotor pin must be flush with the surface of the key slot wall, or the minimum configuration is very important about the key slot.

Page 7 Λ 445338 V. Description of the invention ¢ 3) Withdraw slightly, however, the degree of retraction cannot be greater than expected. Third, in order to allow the fixed rotor pin channel to protrude into the key slot, as As you can see, it is necessary to provide a straight line cut made on one of the two large planes of the key body and protruding from the end-end of the key, whereby the key can be introduced into the movable driver base as much as possible. In the opening. The use of the cut marks reduces the possibility of making hollow grooves on the two large flat surfaces of the key body, and as a result, there are several possible locking methods between the rotor and the stator of the lock core. In French Patent No. 2, 5 2 1, 2 01, the base of the movable driver is made on the main plane of the key body, and preferably at each end, is opened to the two longitudinal sides of the key body. The top of one of the narrow edges. The notch is necessary for the channel of the fixed rotor pin protruding into the key slot, and the notch is made on one of the two longitudinal narrow edges of the key body; The reason for repositioning on two large planes of the key body, and the latter can be applied to four slots hollow throughout its entire surface. Furthermore, the driver base and the driver already have a length that is substantially equal to the width of the key body, and is no longer the same as the thickness of the key body of the French patent mentioned above; please note that the increase of these components The necessary machining allowance for size 1 can be easily obtained. Moreover, the movable driver can also have a longer stroke on its base, so that the configuration of the associated movable rotor pin is in accordance with French Patent No. 2, 4 9 Compared with the corresponding rotor pin described in No. 2, 8 7 No. 2, it can retract quite a bit about the wall of the key slot.

Page 8 ^ 445338 V. Description of the Invention (4) The solution described in F R-A No. 2, 5 2 1, 2 01 is valid and satisfactory. However, as mentioned above, the cutout must be provided for the channel of the fixing pin, which somewhat complicates the manufacture of the key and limits the possibility of using its narrow edge. Furthermore, the movable driver can protrude laterally about the largest lateral dimension of the key; as a result, when the key enters the base, the movable driver has the risk of defining the wall of the rotor base to be hooked; in fact It is necessary to provide a truncated conical surface at this entrance. If the driver should pass through the base, the surface is like forming an inclined surface through which the movable driver can move into its base. The lock core occupies space in the axial direction and above the truncated conical surface provided by the key entry, and can be seen from the outside, whereby we can infer that the key intended to operate the lock core is provided with This is a disadvantage of the key of the movable drive. European Patent No. 154, 7 5 5 describes a key for a security lock core, which is particularly suitable for the operation of a lock or a latch. The key is obtained by processing an elongated flat-shaped key body, which is used to insert the key. In the key slot of the lock rotor, the key body has a height-restricted area at its load end, and at least one cross base is provided thereon, which extends laterally about the longitudinal axis of the key and is substantially parallel to the The middle plane of the key is opened on the opposite narrow edge of the reduced area. The base is suitable for a movable drive capable of transmitting movement within a limited range. The drive uses a lateral end to communicate with the key. An external positioning element interacts with the longitudinal opening of the rotor key slot, and is used to push a movable rotor pin into a position by its opposite lateral end 1 so that the rotor is about the center of the lock.

Page 9 5. Description of the invention (5) The stator rotates. Because of the point, it is no longer necessary to face, or the movable driving key is provided for the purpose of the present invention, and the key end of the key body is retracted from the entrance of the key recording base to provide a positioning element for the positioning element. The channel key is used to copy the key for the user to make a cut. The key is made by a security lock. This key is particularly suitable for this key. The key axis is transmitted across the rotor and the rotor shaft is moved. The rotating device is moved to the base that drives at least one of the formed bases. The purpose is to move the phase actuator of the spoon body to the ground spoon. The key slot has at least two longitudinal actuators. The cut surface has its side; the drive will make the lose, so as to mention that the present invention is derived from the operation of the lock or the latch, and its use is less about a kind of, the key to be inserted into the base of the lock in parallel It is opened on the edge, and the inner side is about the extension, and the narrow sides of the pair are sufficient to limit the range. The driver is more complex with the outside of the key for better security and safety lock. It is the input of the careful rotor by the force σ. The middle of the iron key, the base is suitable for a transverse end element of the key body to interact with the main positioning of the key, and is used to horizontally close the device, thereby moving a movable rotor. The pin is pushed one bit and the lock core rotates one side. The shape of at least one end of the plane axis of the plane and the side of the plane at the end of the cross section and the longitudinal belly with at least one actuator. It is characterized in that at least one axis located on its cross section passing through a lateral edge upper node intersects, the input opening opens the entrance to the 闬 to pass through the superior conical center of the opening area, and the input In the key, in the long flat outer key slot, the longitudinal plane of the key is transverse to at least one longitudinal axis, and its use is centered with the body's longitudinal direction, so that the movable drive is vertical. In the definition part, the key The main body in the drive is less ^ ~~-

Page 10 V. Description of the invention (6) The movable rotor pins interact so as to push them into a position that rotates the rotor about the stator, the correlation between the side profile of the driver and the associated movable pin The position is determined by the positioning element. In a first alternative embodiment of the present invention, the key body is processed at a load-restricted area at the load end thereof, and a base of the movable driver is provided thereon. In another alternative embodiment, the base of the movable driver is provided at the load end of the key body, and it opens at each lateral end into all the longitudinal cuts on the narrow edge of the key body, and the base has The lateral dimension is substantially equal to the height of the key body. This alternative implementation c falls within the general scope of Patent Nos. 2,5 2 1, 201. Preferably, the movable actuator moves according to an axis, and at least one cross section of the movable actuator passes through a plane perpendicular to its displacement axis, and is not generated by rotation about the displacement axis, so that the actuator does not Will turn in its base. For example, the movable actuator has a substantially flat shape, which extends according to the middle plane of the key body. In this example, the driver may have at least one groove on at least one of its two large sides, forming the variation described above, and making an opening in the key body, substantially corresponding to each groove Consistent. In a special form of embodiment, the one or more grooves are manufactured on at least one rib protruding on the larger side of the driver, the rib extending in a plane perpendicular to the longitudinal axis of the key body. Preferably, the driver is machined on at least one of the two parallel groove ribs on its larger surface, consistent with the opening of the opening, and the opening is manufactured on the key body as the movable rotor.

Page 11 dA5338 V. Description of the invention (7) Channel of pin. Preferably, each of the four slots has a generally V-shaped opening facing the flank of the key, so as to define a plurality of possible positions along the V-slope to contact the movable rotor pin, so that the movable rotor pin A change in position 1 causes the rotor to rotate about the stator. According to another feature of the present invention, the base of the driver has a blind recess in the longitudinal direction of the key body. The recess is suitable for the longitudinal extension of the driver. The driver has a lateral dimension smaller than the dimension of the recess. In order to limit the lateral movement of the drive in its base. According to another feature, the reduced area has the same thickness as the remainder of the key body. The advantage lies in the lateral size of the reduced area and the configuration of the movable drive 'and its seat, so that when the drive is completely away from its base, the drive can protrude laterally with respect to the outline of the cross section of the remaining part of the key body. According to another feature, the lateral size of the movable driver is larger than the height of the reduced area and smaller than the height of the key body. Preferably, the key is reversible, while the lateral appearance of the driver and the opening of the key body are symmetrical about the longitudinal axis of the key. The invention also relates to a safety lock core, which includes a rotor and a stator. The rotor has a keyhole with a substantially rectangular portion. The history of the lock core is based on a key with a movable drive as described above. Operation, the lock core has a positioning element consistent with the key slot for interacting with the lateral end of the movable driver, and at least one movable pin is radially fixed in the rotor and opened into the key slot so that Interact with the movable driver

Description of the invention on page 12 ¢ 8) It is characterized in that it has at least one lateral movable pin, which is fixed radially in the rotor and extends to one side of the key slot for passing through the key body One of the openings interacts laterally with the movable driver. In a first alternative embodiment, the positioning element is formed by an inner surface of the stator perforation. In another alternative embodiment, the positioning element is a wedge fixed in a recessed hole in the longitudinal opening of the key slot, and the lateral dimension of the wedge consistent with the key slot is at most equal to the perforation of the stator The height of the remaining space between the inner surface and the narrow edge of the reduced area of the key body. Preferably, the rotor is suitable for accommodating replaceable wedges with different lateral dimensions in order to adjust the drive with respect to the laterally movable pin? Then the outward positioning. According to another feature, the rotor has at least one laterally movable pin located on two parallel planes perpendicular to the longitudinal direction of the key slot for interacting with the laterally outward shape of the movable driver. The advantage is that the lock core has at least one bottom movable pin, which is radially fixed to the rotor and through the lateral movable pin or on the lateral plane near it, and terminates at the bottom of the key slot to communicate with the movable driver. The opposite lateral ends interact. According to another feature, the bottom movable pin is located on a middle plane of the key slot. In another alternative embodiment, the bottom movable pin and the middle plane of the key slot form an acute angle.

O: \ 57 \ 57630.ptc Page 16b 2001.03. 08.018 V. Explanation of the invention (12) is outstanding. The narrow edge of the upper part of the key body 3 has a longitudinal concave groove 3§ on the middle plane of the key body 3, as shown in FIG. In FIG. 3, a lock core 5 has a stator housing 6 and a cylindrical stator 7, which has a cross section in the form of a circular ring, and is processed with a cylindrical perforation 7 denier, and a rotor 4 is embedded therein for rotation. . The rotor 4 has a shape of a rotary lock core and has several axes in common with the stator 7. As shown in Figs. 17 and 18, the rotor 4 has a key slot 8 whose cross section is rectangular and slightly larger than the rectangle of the key body 3, so that the latter can penetrate into the interior of the key slot 8. The keyway 8 is formed by a cross recessed groove that extends the entire length of the rotor 4 and opens through a longitudinal opening 9 to a cylindrical surface outside the rotor 4. The opposite wall of the key slot 8 and the opening 9 constitutes the bottom 8 of the key slot. The bottom 8 is connected to the outer surface of the rotor 4 by two substantially parallel lateral walls. At the entrance to the key slot 8, the rotor 4 has a connector in the form of a protrusion 10 for sliding on the narrow edge k of the upper part of the key body 3 in the four longitudinal grooves 3 (as shown in FIG. 3). ). Now refer to FIG. 4 = show a double lock core = the left-hand part and its right-hand part have exactly the same components: the double lock core component is similar to the single lock core component shown in Figure 3, with Have the same reference numbers. The double lock core here has two stators 7 which are connected by a longitudinal rod 1 1, each stator 7 receiving its own rotor 4. In the traditional method, 'each rotor has an outer peripheral duct (see 12 in Fig. 3), which is used to receive a detent spring 13 to lock each rotor longitudinally in its associated stator. A key block 14 is arranged between two buckle springs 13 to actuate the lock element. The key block 14 has a cylindrical collar, which is the

Page 17 440338 t < ^ ^ 〇 5. Description of the invention (13) The two axially inward pushing ends, the collar has a middle retaining ring 15. The same key block 14 has a pull lever 16 arranged radially about the collar. A slider (not shown) is used to connect / unlock the key block 14 on the rotor 4 as a function of the existence of the key associated with the rotor. In the middle of the connecting rod 11, a perforation 17 is used to fix the lock core, for example on a door. There are multiple locking methods between each rotor 4 and the associated stator 7 so as to form a combination that allows the rotor 4 to rotate only when the appropriate key 1 is introduced into the key slot 8. These locking methods may be provided by movable rotor pins, such as pins 18 and 19 shown in Fig. 9, which are associated with corresponding movable stator pins 20, 21. The movable rotor pins 18, 19 can be slidably inserted into the bases 2 2, 2 3, respectively. The base is radially manufactured in the rotor 4, and each base includes two parts with different diameters, and a ring is defined therebetween. Shaped shoulders 2 2 mesh, 2 3 denier. Each base 22, 2 3 is opened into the interior of the key slot 8 via a smaller diameter portion, and is opened into the cylindrical outer surface of the rotor 4 via its larger diameter portion. Similarly, each pin 18, 19 has two parts with different diameters, corresponding to the diameters of the two parts of the base 2 2, 2 3, especially one part forming a shank and connected to one part, the The part forms a larger diameter head 18, 19 beans. Each of the heads 18 interacts with each other, and 19 counties carry the corresponding stator pins 2 Q, 2 1 = which are in the form of a hollow cover, and can slid into the steering base 2, 4 5 of the stator 7 respectively. in. Each of the stator pins 20, 21 is a spring 26 that elastically pushes the heads 18a, 19 of the rotor pins 18, 19. For the predetermined angular position of the rotor 4 with respect to the stator 7, which is shown in Fig. 9, the bases 2 2, 24 and 23, 25 have axes aligned with each other.

Page 18 ^ H〇 ^ 3 d_ · 4 45 3 3 8___ V. Description of the invention (14) When the key body 3 is not introduced through the key slot 8, the heads 18 of each of the movable rotor pins interact with each other, 19 deniers are individual stator pins 2 0, 2 1 that exert thrust to abut the shoulders 22 2 deniers 2 3 of the individual bases 22, 23. The depth of the larger diameter part of the base 22, 2 3 is greater than the thickness of the head 18 denier and 19, so that the stator pin 2 0, 2 1 penetrates into the base 2 2, 2 3 and is larger. For the diameter part, the diameter of the base 2 4, 2 5 is the same as that of the larger diameter part of the base 2 2, 2 3. As a result, any rotation of the rotor 4 with respect to the stator 7 can be prevented by the stator pins 20, 21. In the circle 4, a plurality of bases 23 are shown along the rotor 4 as movable rotor pins. When the key body 3 is introduced into the key slot 8, it is provided by hollow serrations (not shown) provided on the larger side of the key body 3, or by teeth (not shown) on the narrow edges of the key body 3. (Shown), the movable rotor pin 1 8 and Γ 9 will be pushed backwards and abut the impeachment 26. If the right-hand recording key is not used, the heads of the movable rotor pins 18, 19 are 18 deniers, 19 will protrude into the bases 24, 25 of the stator 7, and will prevent the rotor 4 from rotating about the stator 7. . Only when the key 1 occupies the correct position 1 and all the movable rotor pins interact with the associated hollow serrations, the bearing surface between the rotor pin head and the stator pin will be placed on the cylindrical surface of the rotor It is then possible to turn the rotor about the stator by the action of the blade 2 of the key 1. This hollow sawtooth is shown as c in Fig. 1 of European Patent No. 1, 54, 75 5, which is incorporated herein by reference. The head of the key 1 will now be described in detail, that is, the end of the key body 3 away from the sheet 2. The head of the key 1 has a reduced area 30, in which a cross base 31 is manufactured, with respect to the longitudinal direction of the key and the main body of the key.

Page 19 445338 V. Description of the invention (15) The middle plane of the body 3 extends laterally 13 as shown in Figure 2. The reduced area 3 0 has the same thickness e as the rest of the key body 3, but its height h ( FIG. 1A) is smaller than the height Η of the remaining part of the key body 3. At both ends, the base opens on the narrow edge of the reduced area 30. In the base 31, a movable driver 32 is provided for interacting with a positioning element 33. In Figs. 3, 4 and 9, the element 33 is formed by a wedge or insert fixed in a recessed hole. Formed, and the recess is located on the opening 9 of the keyway 8 of the rotor 4, the insert 3 3 ^ passes through the rib 33 beans with a convex surface on the middle plane of the keyway 8, and the radial direction Ground protrudes toward the inside of the key slot 8, and the convex surface of the convex surface faces the bottom 8 a of the key slot 8, so that the movable driver 32 can be displaced upward at the end of the key leading into the lock core. The outer surface of the insert 33 immediately follows the outer cylindrical surface of the rotor 4, so as not to hinder the rotation of the rotor about the stator. The insert 33 can be fixed by any suitable device on the rotor 4, and can be fixed in the recessed hole of the rotor by close fitting. As shown in FIGS. 3 and 4, the axial locking manner of the rotor 4 with respect to the stator 7 firstly interacts with the stator 7 through a flange 28 located at one end of the rotor, and the second system is fixed by A split elastic ring 1 3 1 in the channel 12 is located on an end of the outer surface of the rotor 4 facing away from the flange 28, and the ring 13 interacts with the remaining ends of the stator 7. As shown in FIGS. 1, 1 A, and 1 @, the reduced area 30 has at least one opening 34 on each of the larger sides 30a, 3 leaves, and opens into the lateral base 31. The opening 3 4 has a shape that is gradually widened toward the outside,

When the recording key 1 guides the lock core, the shaft and the side of the movable rotor lock such as The axes of the pins 19 are relatively aligned. Now referring to FIGS. 5 to 7, the first embodiment of the driveable drive 32 will be described. The drive includes a small, flat piece 35, which extends substantially on the middle plane of the key body 3. The month 35 has raised edges 36 and 36 beans at each lateral end for interacting with the positioning element 33 and a movable rotor pin such as the bottom pin 18, respectively. The sheet 35 further has a longitudinal extension 37 having a lateral dimension 1 smaller than the height of the reduced area 30, and the extension 37 is received in a blind recess of the base 31 to limit the The extent to which the driver 32 slides, and to prevent the driver from falling off from the base 31. However, the lateral dimension of this extension 37 makes the driver 32, when the driver is retracted from its base to the maximum, A portion is exposed from the pedestal 3 丨 beyond the narrow edge of the reduced area. Domain 30 and protrudes laterally with respect to the outline of the cross section of the remaining part of the key body 3. In the manufacture of the key 1, the base 31 The two lateral ends are completely opened to allow the movable driver 32 to be introduced, and then, after the driver is inserted, the driver's extension 3 7 is clamped by the back of the key end material to be clamped. In the base 31, in order to define the blind recess described above. Preferably, the lateral dimension of the driver 32 is substantially larger than the height h of the reduced area 30 and smaller than the size of the key body 3. The height is Η, but the same It is possible to provide a driver with a lateral dimension equal to or even smaller than the height h of the reduced area 30, in which case the movable rotor pin 18 can partially penetrate into the base 3 1 of the driver in.

Page 21 446338 V. Description of the invention (17) The driver 3 2 additionally has a protruding rib 38, 39 on each of the larger sides of the 35, which is substantially perpendicular to one of the longitudinal directions of the key Plane extension. Each of 38, 39 has a groove or cut 40, 41, which has a generally V-shaped opening toward the side wall 30 of the reduced area 30 and 3 0 &, and extends in the lateral direction of the base 31. The grooves 40 and 41 are positioned on the ribs 38 and 39, so as to be substantially consistent with the opening 34, so that the lateral movable rotor pin can pass through the opening 3 4 = and the V -The slopes of the arms are in contact. As shown later, the slope of the V makes it possible to define a number of possible positions in contact with the laterally movable rotor pin.

The grooves 40 and 41 on each side of the driver 32 can be positioned at different heights in the lateral direction. The grooves 40 and 41 exceed at least a part s of the segment, and the segment is defined between two frontmost planes P Γ and P 2 of the cross section of the driver. In other words, the length of the groove is smaller than the length of the driver in the axial direction of the key body. As shown in FIG. 2, the base 3 丨 of the key reduction area 30 has a side contour complementary to the driver 32. Referring again to FIG. 9, it is shown that the driver 32 is located at its maximum protruding position with respect to the reduced area 30 toward the movable rotor pin 18, and the movable rotor pin 18 is located at the bottom 8 of the key slot 8. Each other and is aligned with the lateral direction of the driver 3 2. In this position, the movable actuator 32 bears its lower protruding edge 36 denier on the apex of the convex rib 33 of the positioning wedge 33, and bears on the conical wearing end of the movable pin 18. Their opposite protruding edges are 3 6 each other. Here the protruding edge 3 penetrates into the inside of the base 22 of the rotor pin. The laterally movable pin 19 of the rotor 4 passes through the reduced area 30

Description of the invention (18) The opening 34, and its rounded tip, which is located approximately at the center of the V in the groove of the driver 32, or at the v The bottom of the bevel of the arm. The base for which it is a laterally movable rotor pin is shown in dashed lines of 123. In the alternative embodiment according to FIG. 10, the pin 8 is replaced by the pin n 8, which forms an acute angle g with the middle plane of the key 4 cup 8. The pin η 8 extends to the bottom of the key recording groove 8 ^ 8d 'is used to carry one side of the protruding edge 36b of the driver 32: the lock il8 here has a rounded tip. Therefore, because the tip of the pin 118 does not carry the apex of the protruding edge 36g of the driver 32, the length of the pin Η8 is substantially greater than the length of the pin 丨 8. As shown in FIG. 13, the The positioning wedge 3 3 is replaced by another positioning wedge-1 33 'which has a convex rib of a lower height 3 3§. Therefore, the upper protruding edge 36b of the driver 32—the base w with respect to the reduced area 30 of the key—is positioned at different heights. The movable rotor pin 2 1 8 ′ placed on the plane between the key groove 8 and therefore has a larger length than the pin 18, when the tip of the truncated cone is in contact with the edge 36 of the driver 3 2 , So that the lock can be unlocked. When the driver 32 moves downward with respect to the reduced area 30; the side lock U9 facilitates different positions to contact the groove 41 of the driver 32. In FIG. 13, 'the pins 1 9 and 9 contact the V-slope of the groove 41 approximately halfway. Therefore, 'the pin 119 must have a smaller length than the pin 19 previously described. In the alternative embodiment according to FIG. 14, the bottom pin 318 is inclined at one side of the middle plane ′ 纟 and the upper edge of the driving n32.

Page 23 ^ 4ab 3 3 a 5. Description of the invention [19] Contact in a manner similar to the pin 18 in Fig. 10. The positioning wedges 3 3 and 1 3 3 are convex, the ribs 3 3 are mutually, and the sides of 1 3 3 are provided with fins 33 & 133, which extend in the opposite direction perpendicular to the middle plane of the key slot 8, And used to insert into the connecting base of the rotor. In FIG. 17, the positioning wedges 33 and 133 are omitted, and the inner cylindrical surface of the stator 7 passing through L 7 denier acts as the positioning of the lower protruding end 3 6 a_ of the driver 3 2. element. Then, the driver 32 is located at the position of the maximum downward projection, and its upper end edge 3 is flush with the narrow edge above the key reduction area 30. Therefore, the rotor pin 4 1 8 located on the middle plane of the key slot 8 has a longer length than the pin 2 1 8 described above. After the driver 3 2 is completely moved downward, one side faces the rotor pin 2 1 9 耒. The apex of the inclined surface of the driver 3 2 V-shaped groove 41 is loaded. Therefore, the length of the pin 2 1 9 must be smaller than the length of the pin 1 1 9 described above. Therefore, it can be understood from FIGS. 9 to 8 that the length of the movable rotor pin can be in the reduced area 30 of the key 1 as a function of the height of the positioning element, and can be achieved by the existence of the groove. The key is inserted in a number of different degrees. Similarly, the length of the pin at the bottom of the rotor may vary as a function of the degree of inclination of the pin with respect to the upper edge 36 of the driver 32. Because generally unauthorized persons do not know the extent to which the side lock is inserted into the keypad to reduce the area, it is much more difficult for such persons to duplicate the key. Therefore, with a single driver, it is possible to obtain various positions of the lateral pin and the bottom pin of the rotor; since the height of the positioning element can be changed, the variability can be increased even more.
